PR cli/21688: Detect aliases when issuing python/compile/guile commands (and fix last commit)
My last commit fixed a regression that happened when using
inline/multi-line commands for Python/Compile/Guile, but introduced
another regression: it is now not possible to use aliases for the
commands mentioned above. The fix is to almost revert the change I've
made and go back to using the 'struct cmd_list_element *', but at the
same time make sure that we advance the 'cmd_name' variable past all
the whitespace characters after the command name. If, after skipping
the whitespace, we encounter a '\0', it means that the command is not
inline. Otherwise, it is.
This patch also expands the testcase in order to check for aliases and
for trailing whitespace after the command name.

PR cli/21688: Fix multi-line/inline command differentiation
This bug is a regression caused by the following commit:
604c4576fdcfc4e7c28f569b3748a1b6b4e0dbd4 is the first bad commit
commit 604c4576fdcfc4e7c28f569b3748a1b6b4e0dbd4
Author: Jerome Guitton <guitton@adacore.com>
Date: Tue Jan 10 15:15:53 2017 +0100
The problem happens because, on cli/cli-script.c:process_next_line,
GDB is not using the command line string to identify which command to
run, but it instead using the 'struct cmd_list_element *' that is
obtained by using the mentioned string. The problem with that is that
the 'struct cmd_list_element *' doesn't have any information on
whether the command issued by the user is a multi-line or inline one.
A multi-line command is a command that will necessarily be composed of
more than 1 line. For example:
(gdb) if 1
>python
>print ('hello')
>end
>end
As can be seen in the example above, the 'python' command actually
"opens" a new command line (represented by the change in the
indentation) that will then be used to enter Python code. OTOH, an
inline command is a command that is "self-contained" in a single line,
for example:
(gdb) if 1
>python print ('hello')
>end
This Python command is a one-liner, and therefore there is no other
Python code that can be entered for this same block. There is also no
change in the indentation.
So, the fix is somewhat simple: we have to revert the change and use
the full command line string passed to process_next_line in order to
identify whether we're dealing with a multi-line or an inline command.
This commit does just that. As can be seen, this regression also
affects other languages, like guile or the compile framework. To make
things clearer, I decided to create a new helper function responsible
for identifying a non-inline command.
Testcase is attached.

MIPS: Fix XPA base and Virtualization ASE instruction handling
Correct a commit 7d64c587c15f ("Add support for the MIPS eXtended
Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization
ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.
For example this source assembles successfully as shown below:
$ cat xpa.s
mfhc0 $2, $1
$ as -32 -mips32 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1'
$ as -32 -mips32r2 -o xpa.o xpa.s
$ objdump -d xpa.o
xpa.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <.text>:
0: 40420800 mfhc0 v0,c0_random
...
$
To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table. Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).
Now the same source is correctly rejected unless the `-mxpa' option is
also used:
$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1'
$ as -32 -mips32r2 -mxpa -o xpa.o xpa.s
$
Add test cases for XPA base and XPA Virtualization ASE instructions.

MIPS/opcodes: Correctly combine ASE flags for ASE_MIPS16E2_MT calculation
Correct a commit 25499ac7ee92 ("MIPS16e2: Add MIPS16e2 ASE support")
disassembler bug with the handling of the ASE_MIPS16E2_MT combination
ASE flag, where the calculation uses MIPS ABI Flags directly rather than
calculated internal ASE flags. Consequently code does not correctly set
the ASE_MIPS16E2_MT flag when the MIPS16e2 ASE flag and the MT ASE flag
come from different sources, i.e. one from the BFD chosen and the other
one from MIPS ABI Flags.
Fix this by using internal ASE_MT and ASE_MIPS16E2 flags in a separate
subsequent step, factored out to a dedicated function for use with
future combination ASE flags. Adjust the `mips16e2@mips16e2-mt-sub.d'
test case accordingly, where the MT flag comes from the BFD selected for
the disassembler and the MIPS16e2 flag comes from the ELF binary itself.

MIPS/GAS: Clear the ASE_MIPS16E2_MT flag for recalculation
Correct a commit 25499ac7ee92 ("MIPS16e2: Add MIPS16e2 ASE support") GAS
bug with the handling of the ASE_MIPS16E2_MT combination ASE flag, which
is not correctly calculated as `.set nomips16e2' and `.set nomt'
pseudo-ops are processed. This leads to code like:
$ cat foo.s
.set nomt
evpe
.align 4, 0
$ cat bar.s
.set nomips16e2
dvpe
.align 4, 0
$
to successfully assemble where it should not:
$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o foo.o foo.s
$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o bar.o bar.s
$ objdump -m mips:16 -d foo.o
foo.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <.text>:
0: f027 6700 evpe
...
bar.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <.text>:
0: f026 6700 dvpe
...
$
This happens because ASE_MIPS16E2_MT once set in `mips_set_ase' is never
cleared. Fix the problem by clearing it there before it is calculated
based on the ASE_MT and ASE_MIPS16E2 flags, making assembly fail as
expected:
$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o foo.o foo.s
foo.s: Assembler messages:

Expression completer should not match explicit location options
This commit fixes a mismatch between what "print" command completer
thinks the command understands, and what the command actually
understands.
The explicit location options are understood by commands that take
(linespecs and) explicit locations as argument. I.e, breakpoint
commands, and "list". For example:
(gdb) b -source file.c -function my_func
So for those commands, it makes sense that the completer
completes:
"b -sour[TAB]" -> "b -source "
"b -functi[TAB]" -> "b -function "
etc.
However, completion for commands that take expressions (not
linespecs/locations) as arguments, such as the "print" command, also
completes the explicit location options, even though those switches
aren't really understood by these commands. Instead, "-foo" is
understood as an expression applying unary minus on a symbol named
"foo" (think "print -1"):
(gdb) p -func[TAB]
(gdb) p -function [RET]
No symbol "function" in current context.
The patch fixes this by having the expression_completer function
bypass the function that completes explicit locations.
New regression tests included.

[ARC] Fix handling of cpu=... disassembler option value
There is a bug in handling of cpu=... disassembler option in case there are
other options after it, for example, `cpu=EM,dsp'. In this case `EM,dsp' is
treated as an option value, and strcasecmp reports is as non-equal to "EM".
This is fixed by using disassembler_options_cmp function, which compares string
treating `,' the same way as `\0'.
This function also solves a problem with option order in parse_option.
Previously, if several option had same prefix (e.g. fpud, fpuda), then the
longer one should have been compared first, otherwise when longer option is
passed it would be treated as a short one, because
CONST_STRNEQ ("fpud", "fpuda")
would be true. The order of options was correct for ARC, so there were no
bugs per se, but with disassembler_option_cmp there is no risk of such a bug
being introduced in the future.

bfd: prevent all but undef weak syms from becoming dynamic in sparc.
Prevent sparc backend making symbols dynamic unless they are undefined
weak. Use R_SPARC_RELATIVE for the symbols which are not dynamic in PIC.

[AArch64] Only override the symbol dynamic decision on undefined weak symbol
This fix is an adaption of the x86-64 PR ld/21402 fix to AArch64.
After the generic code deciding one symbol is not dynamic, AArch64 backend
only overrides the decision on undefined weak symbols.

[AArch64] Remove duplicated code when handling some GOT relocations types
There are quite a few duplicated code supporting several GP based
relocation types. They are:
BFD_RELOC_AARCH64_LD64_GOTOFF_LO15
BFD_RELOC_AARCH64_MOVW_GOTOFF_G0_NC
BFD_RELOC_AARCH64_MOVW_GOTOFF_G1
These relocation types are supposed to be used for large memory model PIC/pic
mode under which we will have an initialized GP register points to the base of
GOT table, then these relocations are supposed to put the distance between GOT
entry and GOT table base address into the related instructions.
So, the parameters required to calculate the relocation should be the same as
BFD_RELOC_AARCH64_LD64_GOTPAGE_LO15 etc, all of them are require the GOT entry
address and GOT table base address to perform the relocation.
This patch has removed those duplicated code when handling above listed
relocation types, grouped them with others as relocation types that are
require GOT table base address during performing relocation, reused the
existed GOT handling code.
The relocation calculation for these types before and after this patch should be
identical.

Author: Doug Gilmore <Doug.Gilmore@imgtec.com>

Fix PR 21337: segfault when re-reading symbols.
Fix issue exposed by commit 3e29f34.
The basic issue is that section data referenced through an objfile
pointer can also be referenced via the program-space data pointer,
although via a separate mapping mechanism, which is set up by
update_section_map. Thus once section data attached to an objfile
pointer is released, the section map associated with the program-space
data pointer must be marked dirty to ensure that update_section_map is
called to prevent stale data being referenced. For the matter at hand
this marking is being done via a call to objfiles_changed.
Before commit 3e29f34 objfiles_changed could be called after all of
the objfile pointers were processed in reread_symbols since section
data references via the program-space data pointer would not occur in
the calls of read_symbols performed by reread_symbols.
With commit 3e29f34 MIPS target specific calls to find_pc_section were
added to the code for DWARF information processing, which is called
via read_symbols. Thus in reread_symbols the call to objfiles_changed
needs to be called before calling read_symbols, otherwise stale
section data can be referenced.
Thanks to Luis Machado for providing text for the main comment
associated with the change.

MIPS: Add Imagination interAptiv MR2 MIPS32r3 processor support
Add support for the Imagination interAptiv MR2 MIPS32r3 processor with
the MIPS16e2 ASE as per documentation, including in particular:
1. Support for implementation-specific interAptiv MR2 COPYW and UCOPYW
MIPS16e2 instructions[1], for assembly and disassembly,
2. Support for implementation-specific interAptiv MR2 SAVE and RESTORE
regular MIPS instructions[2], for assembly and disassembly,
3. ELF binary file annotation for the interAptiv MR2 MIPS architecture
extension.
4. Support for interAptiv MR2 architecture selection for assembly, in
the form of the `-march=interaptiv-mr2' command-line option and its
corresponding `arch=interaptiv-mr2' setting for the `.set' and
`.module' pseudo-ops.
5. Support for interAptiv MR2 architecture selection for disassembly,
in the form of the `mips:interaptiv-mr2' target architecture, for
use e.g. with the `-m' command-line option for `objdump'.

objfile_per_bfd_storage non-POD
A following patch will want to add a std::vector to
objfile_per_bfd_storage. That makes it non-trivially
constructible/destructible. Since objfile_per_bfd_storage objects are
allocated on an obstack, we need to call their ctors/dtors manually.
This is what this patch does. And then since we can now rely on
ctors/dtors being run, make objfile_per_bfd_storage::storage_obstack
be an auto_obstack.

Eliminate make_cleanup_obstack_free, introduce auto_obstack
This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.
These changes in the parsers may not be obvious:
- obstack_init (&name_obstack);
- make_cleanup_obstack_free (&name_obstack);
+ name_obstack.clear ();
Here, the 'name_obstack' variable is a global. The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts. I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.
The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases. I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

Fix PR 13402
Fix incorrect adjustment of diff relocs when relaxing, and thus the
resulting source line to address mismatch.
Fix two issues when adjusting diff relocs to account for
deleted bytes.
1. Don't adjust the difference if the end address is the shrinked
insn's address i.e. use < instead of <=. The relaxation code deletes
count bytes from or after shrinked_insn_address, so the difference
between start_address and end_address should remain unchanged in this
case.
2. Adjust the reloc addend if the difference is to be adjusted and
symval + reloc addend is past the shrinked insn address. This is
because for a typical sym1 - sym2 diff reloc, sym1 is .text +
irel->r_addend, and the addend should be reduced to account for the
shrinked insn.
For example, assume the reloc value is .text + 0x8 with .text = 0, the
diff value in the object file = 0x4, and shrinked_insn_address = 0x4
with count = 0x2. Then the existing code writes 0x2 into the object
file to account for the deleted bytes, as shrinked_insn_address lies
between 0x8 and 0x8 - 0x4 = 0x4, but leaves the addend as is. The next
time the reloc is looked at, the code sees if a shrinked_insn_address
lies between 0x8 and 0x8 - 0x2 = 0x6, instead of 0x6 and 0x4. If there
happens to be one, then the diff value in the object file ends up
getting reduced again.

darwin: Do not add a dummy thread
Starting a process on macOS/Darwin currently leads to this error:
/Users/simark/src/binutils-gdb/gdb/darwin-nat.c:383: internal-error: void darwin_check_new_threads(struct inferior *): Assertion `tp' failed.
with the corresponding partial backtrace (sorry, taken with lldb,
because well, gdb is broken :)):

The issue was introduced by commit
"Share fork_inferior et al with gdbserver"
because it changed the place where the dummy thread (pid, 0, 0) is added,
relative to the call to the init_trace_fun callback. In this callback, darwin
checks for new threads in the program (there should be exactly one) in order to
update this dummy thread with the right tid. Previously, things happened in
this order:
- fork_inferior calls fork()
- fork_inferior adds dummy thread
- fork_inferior calls init_trace_fun callback, which updates the dummy
thread info
Following the commit mentioned above, the new thread is added in the
darwin-nat code, after having called fork_inferior (in
darwin_create_inferior). So gdb tries to do things in this order:
- fork_inferior calls fork()
- fork_inferior calls init_trace_fun callback, which tries to update
the dummy thread info
- darwin_create_inferior adds the dummy thread
The error happens while trying to update the dummy thread that has not
been added yet.
I don't think this dummy thread is necessary for darwin. Previously, it
was fork_inferior that was adding this thread, for all targets, so
darwin had to deal with it. Now that it's done by targets themselves,
we can just skip that on darwin. darwin_check_new_threads called
indirectly by init_trace_fun/darwin_ptrace_him will simply notice the
new thread and add it with the right information.
My level of testing was: try to start a process and try to attach to a
process, and it seems to work somewhat like it did before. I tried to
run the testsuite, but it leaves a huge amount of zombie processes that
launchd doesn't seem to reap, leading to exhaustion of system resources
(number of processes).
gdb/ChangeLog:
* darwin-nat.c (darwin_check_new_threads): Don't handle dummy
thread.
(darwin_init_thread_list): Don't update dummy thread.
(darwin_create_inferior, darwin_attach): Don't add a dummy thread.

MIPS/LD/testsuite: mips-elf-flags: Add MIPS ABI Flags handling
Complement commit 351cdf24d223 ("[MIPS] Implement O32 FPXX, FP64 and
FP64A ABI extensions") and add optional MIPS ABI Flags handling to
`good_combination' in the `mips-elf-flags.exp' test script. This lets
callers of this procedure request to examine MIPS ABI Flags in addition
to the `e_flags' member of the ELF file header so as to verify that
flags are merged correctly by LD. The presence of further arguments
triggers this verification, in which case `readelf' is called with the
`-A' option additionally specified and the ISA member, the ISA Extension
member and the ASEs member will be examined as per the arguments.
Unlike with `readelf -h' output consider a failure to retrieve the
member requested a test case failure rather than an unresolved result.
This is because unlike with the `e_flags' member of the ELF file header
which is always there in any valid ELF file the MIPS ABI Flags structure
is optional in LD output and the absence of this structure when expected
is surely a bug in LD.
ld/
* testsuite/ld-mips-elf/mips-elf-flags.exp (good_combination):
Add an `args' final argument and examination code for `readelf
-A' output. Update procedure description accordingly.

MIPS/LD/testsuite: mips-elf-flags: Use `remote_exec' to call `readelf'
For ELF file header flag verification done in `good_combination' in the
`mips-elf-flags.exp' test script the version of `readelf' built along
with the rest of binutils has to be used rather than any such executable
already present on the build system, so that flags recognized by the
tool match those supported by LD being tested. Use `remote_exec' as
elsewhere in the LD test framework and also with GAS and LD used here,
getting and arranging for extra reporting of `readelf' calls included in
test logs on this occasion as well.

and ignores data from any ELF program or section headers present. Use
`readelf -h' rather than `readelf --headers' then to obtain data for
examination, avoiding unnecessary processing to extract this extraneous
information.

latter's 32-bit instructions are concerned and consequently can only be
considered a MIPS II ISA implementation (with vendor extensions).
This fixes an LD testsuite failure:

LD: Fix .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX
Correct .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX targets,
complementing commit dc74becf498f ("ld: Add tests for -Ur") and commit
da614360f520 ("ld: Add tests for .startof.SECNAME/.sizeof.SECNAME") with
subsequent updates, and in reference to commit cbd0eecf261c ("Always
define referenced __start_SECNAME/__stop_SECNAME") and commit
7dba9362c172 ("Rewrite __start and __stop symbol handling").
These targets set the STT_OBJECT type for non-function symbol
references, according to `elf_frob_symbol' code in gas/config/obj-elf.c:
/* The Irix 5 and 6 assemblers set the type of any common symbol and
any undefined non-function symbol to STT_OBJECT. We try to be
compatible, since newer Irix 5 and 6 linkers care. However, we
only set undefined symbols to be STT_OBJECT if we are on Irix,
because that is the only time gcc will generate the necessary
.global directives to mark functions. */
if (S_IS_COMMON (symp))
symbol_get_bfdsym (symp)->flags |= BSF_OBJECT;
if (strstr (TARGET_OS, "irix") != NULL
&& ! S_IS_DEFINED (symp)
&& (symbol_get_bfdsym (symp)->flags & BSF_FUNCTION) == 0)
symbol_get_bfdsym (symp)->flags |= BSF_OBJECT;
and consequently entries in the symbol table listing from `readelf'
produced with these tests do not match the NOTYPE pattern expected,
causing test suite failures:
FAIL: ld-elf/sizeofa
FAIL: ld-elf/sizeofc
FAIL: ld-elf/startofa
FAIL: ld-elf/startofc
specifically with the `mips-sgi-irix5' and `mips-sgi-irix6' targets.
Given that it does not matter for the feature covered by these tests
whether the type of the symbols produced is STT_NOTYPE or STT_OBJECT
adjust the problematic cases to accept either type, removing the
failures observed.

record-full: Remove unused function netorder16
clang shows this warning:
/home/emaisin/src/binutils-gdb/gdb/record-full.c:2344:1: error: unused function 'netorder16' [-Werror,-Wunused-function]
netorder16 (uint16_t input)
^
Remove this function, which, AFAIK, has never been used. Note that GCC
doesn't warn about this, because the function is marked as inline.
According to gcc's man page, it should ideed not warn:
-Wunused-function
Warn whenever a static function is declared but not defined or a non-inline static function is unused. This warning is enabled by -Wall.
So it's probably not a GCC bug that it doesn't find this unused function, but a
different definition of "unused".
gdb/ChangeLog:
* record-full.c (netorder16): Remove.

vec: Silence -Wunused-function warnings on clang
clang has a too aggressive (or broken, depends on how you want to see
it) -Wunused-function warning, which is triggered by the functions
defined by DEF_VEC_* but not used in the current source file. Normally,
it won't warn about unused static inline functions defined in header
files, because it's expected that a source file won't use all functions
defined in a header file it includes. However, if the DEF_VEC_* macro
is used in a source file, it considers those functions as defined in the
source file, which leads it to think that we should remove those
functions. It is therefore missing a check to see whether those
functions are resulting from macro expansion. A bug already exists for
that:
https://bugs.llvm.org//show_bug.cgi?id=22712
It's quite easy to silence this warning in a localized way, that is in
the DEF_VEC_* macros.

* common/diagnostics.h: Define macros for GCC.
(DIAGNOSTIC_IGNORE_UNUSED_FUNCTION): New macro.
* common/vec.h: Include diagnostics.h.
(DIAGNOSTIC_IGNORE_UNUSED_VEC_FUNCTION): New macro.

[ARM] Add linker support for ARMv8-R
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in the linker.
=== Patch description ===
This patch is composed of 3 changes:
1) The main change is the addition of the logic for merging a file whose
Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are
merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into
ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to
merge merge with ARMv8-R. Note that merging only occurs if the two
profiles are identical or one is S (Application or Realtime) and the
other is R.
2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop
are updated according to capabilities of ARMv8-R and their BFD_ASSERT
updated to reflect that the logic is valid for ARMv8-R.
3) 2 build attribute merging tests are added to test the first change.

[ARM] Add support for ARMv8-R in assembler and readelf
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.
=== Patch description ===
Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.
Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.

[ARM] Remove ARMv6S-M special casing
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to remove special casing for ARMv6S-M
autodetection.
=== Motivation ===
Currently, SWI and SVC mnemonics are enabled for ARMv4T and successor
architectures with extra checks in the handler function (do_t_swi) to
give an error message when ARMv6-M is targeted and some more special
casing in aeabi_set_public_attributes. This was made to exclude these
mnemonics for ARMv6-M unless the OS extension is in use.
However this logic is superfluous: there is already code to check
whether an instruction is available based on the feature bit it is part
of and whether the targeted architecture has that feature bit. This
patch aims at removing that unneeded complexity.
=== Patch description ===
The OS extension is already limited to the ARMv6-M architecture so all
this patch does is redefined availability of the ARM_EXT_OS feature bit
to not be present for ARM_ARCH_V6M. ARM_ARCH_V6SM does not need any
change either because it already includes ARM_EXT_OS.
The patch also make sure that the error message that was given by
do_t_swi when SWI/SVC is unavailable is still the same by detecting the
situation in md_assemble.

[GOLD] PowerPC64 tocsave
This adds support to gold for the tocsave relocs already supported by
ld.bfd. R_PPC64_TOCSAVE relocs are part of a scheme to move r2 saves
to the prologue of a function rather than in each plt call stub. We
don't want a compiler to always emit the r2 save, as this would be
wasted if the calls turned out to be local. See the tocsave*.s in

x86: Support Intel IBT with IBT property and IBT-enable PLT
To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
#define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002
#define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)
are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.
GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.
The followings changes are made to the Procedure Linkage Table (PLT):
1. For 64-bit x86-64, PLT is changed to
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
...
PLTn: endbr64
push namen_reloc_index
bnd jmp PLT0
together with the second PLT section:
PLTn: endbr64
bnd jmp *GOT[namen_index]
nop
BND prefix is also added so that IBT-enabled PLT is compatible with MPX.
2. For 32-bit x86-64 (x32) and i386, PLT is changed to
PLT0: push GOT[1]
jmp *GOT[2]
nop
...
PLTn: endbr64 # endbr32 for i386.
push namen_reloc_index
jmp PLT0
together with the second PLT section:
PLTn: endbr64 # endbr32 for i386.
jmp *GOT[namen_index]
nop
BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.
GOT is an array of addresses. Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section. The function, namen, is called via the
ENDBR instruction in the second PLT entry. GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.
2 linker command line options are added:
1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

environ-selftests: Ignore -Wself-move warning
clang gives this warning:
..../gdb/unittests/environ-selftests.c:139:7: error: explicitly moving variable of type 'gdb_environ' to itself [-Werror,-Wself-move]
env = std::move (env);
~~~ ^ ~~~
Ignoring the warning locally is the right thing to do, since it warns
about behavior we want to unit test, while an explicit self-move in
real code would likely be a mistake that we'd want to catch.
To avoid cluttering the code with preprocessor conditionals, this
commit adds the file common/diagnostics.h, in which we can put macros
used to control compiler diagnostics.

Use noncapturing subpattern/parens in gdb_test implementation
This is the portion of gdb_test which performs the match against
the RE (regular expression) passed to it:
return [gdb_test_multiple $command $message {
-re "\[\r\n\]*($pattern)\[\r\n\]+$gdb_prompt $" {
if ![string match "" $message] then {
pass "$message"
}
}
In a test that I've been working on recently, I wanted to use
a backreference - that's the \1 in the the RE below:
gdb_test "info threads" \
{.*[\r\n]+\* +([0-9]+) +Thread[^\r\n]* do_something \(n=\1\) at.*}
Put into English, I wanted to make sure that the value of n passed to
do_something() is the same as the thread number shown in the "info
threads" Id column. (I've structured the test case so that this
*should* be the case.)
It didn't work though. It turned out that ($pattern) in the RE
noted above is capturing the attempted backreference. So, in this
case, the backreference does not refer to ([0-9]+) as intended, but
instead refers to ($pattern). This is wrong because it's not what I
intended, but is also wrong because, if allowed, it could only match a
string of infinite length.
This problem can be fixed by using parens for a "noncapturing
subpattern". The way that this is done, syntactically, is to use
(?:$pattern) instead of ($pattern).
My research shows that this feature has been present since tcl8.1 which
was released in 1999.
The current tcl version is 8.6 - at least that's what I have on my
machine. It appears to me that mingw uses some subversion of tcl8.4
which will also have this feature (since 8.4 > 8.1).
So it seems to me that any platform upon which we might wish to test
GDB will have a version of tcl which has this feature. That being the
case, my hope is that there won't be any objections to its use.
When I looked at the implementation of gdb_test, I wondered whether
the parens were needed at all. I've concluded that they are. In the
event that $pattern is an RE which uses alternation at the top level,
e.g. a|b, we need to make $pattern a subpattern (via parens) to limit
the extend of the alternation. I.e, we don't want the alternation to
extend to the other portions of the RE which gdb_test uses to match
potential blank lines at the beginning of the pattern or the gdb
prompt at the end.

[ARM] Rework Tag_CPU_arch build attribute value selection
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to rework the Tag_CPU_arch build attribute
value selection to (i) match architecture or CPU if specified by user
without any need for hack and (ii) match an architecture with all the
features used if in autodetection mode or return an error.
=== Motivation ===
Currently, Tag_CPU_arch build attribute value selection assumes that an
architecture is always a superset of architectures released earlier. As
such, the logic is to browse architectures in chronological order of
release and selecting the Tag_CPU_arch value of the last one to
contribute a feature used[1]/requested[2] not contributed by earlier
architectures.
[1] in case of autodetection mode
[2] otherwise, ie. in case of -mcpu/-march or associated directives
This logic fails the two objectives mentionned in the Context section.
First, due to the assumption it does an architecture can be selected
while not having all the features used/requested which fails the second
objective. Second, not doing an exact match when an architecture or CPU
is selected by the user means the wrong value is chosen when a later
architecture provides a subset of the feature bits of an earlier
architecture. This is the case for the implementation of ARMv8-R (see
later patch).
An added benefit of this patch is that it is possible to easily generate
more consistent build attribute by setting the feature bits from the
architecture matched in aeabi_set_public_attributes in autodetection
mode. This is better done as a separate patch because lots of testcase'
expected results must then be updated accordingly.
=== Patch description ===
The patch changes the main logic for Tag_CPU_arch and
Tag_CPU_arch_profile
values selection to:
- look for an exact match in case an architecture or CPU was specified
on the command line or in a directive
- select the first released architecture that provides a superset of the
feature used in the autodetection case
- select the most featureful architecture in case of -march=all
The array cpu_arch_ver is updated to include all architectures in order
to make the first point work.
Note that when looking for an exact match, the architecture with
selected extension is tried first and then only the architecture. This
is because some architectures are exactly equivalent to an earlier
architecture with its extensions selected. ARMv6S-M (= ARMv6-M + OS
extension) and ARMv6KZ (ARMv6K + security extension) are two such
examples.
Other adjustments are also necessary in aeabi_set_public_attributes to
make this change work.
1) The logic to set Tag_ARM_ISA_use and Tag_THUMB_ISA_use must check the
absence of feature bit used/requested to decide whether to give the
default value for empty files (see EABI attribute defaults test). It was
previously checking that arch == 0 which would only happen if no feature
bit could be matched by any architecture, ie there is no feature bit to
match.
2) A fallback to a superset match must exist when no_cpu_selected ()
returns true. This is because aeabi_set_public_attributes is called
again after relaxation and at this point selected_cpu is set from the
previous execution of that function. There is therefore no way to check
whether the user specified an architecture or CPU.
3) Tag_CPU_arch lines are removed from expected output when the
detected architecture should be pre-ARMv4, since 0 is the Tag_CPU_arch
value for pre-ARMv4 architectures and default value for an absent entry
is 0.

[ARM] Allow Thumb division as an extension for ARMv7
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to allow ARMv7 to be selected in automatic
architecture selection in presence of Thumb division instructions.
=== Motivation ===
any-idiv.d and automatic-sdiv.d testcases in GAS testsuite expect
autodetection code to select ARMv7 in presence of Thumb integer
division. However, the definition of ARM_AEXT_V7 and thus ARM_ARCH_V7 do
not contain these instructions and the idiv extension is only available
for ARMv7-A and ARMv7-R. Therefore, under the stricter automatic
detection code proposed in the subsequent patch of the series ARMv7 is
refused if a Thumb division instruction is present.
=== Patch description ===
This patch adds a new "idiv" extension after the existing one that is
available to all ARMv7 targets. This new entry is ignored by all current
code parsing arm_extensions such that it would be unavailable on the
command-line and remain a purely internal hack, easily removed in favor
of a better solution later. This is considered though by the subsequent
patch reworking automatic detection of build attributes such that ARMv7
is allowed to match in present of Thumb division instructions. For good
measure, comments are added in all instances of code browsing
arm_extensions to mention the expected behavior in case of duplicate
entries as well as a new testcase.

[ARM] Rework selection of feature bits to base build attributes on
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to set the feature bits on which to decide
what the build attributes should be according to the mode
(autodetection, user specified architecture or CPU, or
-march/-mcpu=all).
=== Motivation ===
Currently, the flags variable which is used to determine the build
attribute is constructed from the instruction used (arm_arch_used and
thumb_arch_used) as well as the user specified architecture or CPU
(selected_cpu). This means when several .arch are specified the
resulting feature bits can be such that no architecture provide them
all and can thus result in incorrect Tag_CPU_arch. See for instance
what having both .arch armv8-a and .arch armv8-m.base would result in.
This is not caught by the testsuite because of further bugs in the
Tag_CPU_arch build attribute value selection logic (see next patch in
the series).
=== Patch description ===
As one would expect, this patch solves the problem by setting flags
from feature bits used if in autodetection mode [1] and from
selected_cpu otherwise. The logic to set arm_ext_v1, arm_ext_v4t and
arm_ext_os feature bits is also moved to only run in autodetection mode
since otherwise the architecture or CPU would have a consistent set of
feature bits already.

[ARM] Simplify Tag_DSP_extension selection logic
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to simplify the logic to decide whether to
set Tag_DSP_extension.
=== Motivation ===
To decide whether to set Tag_DSP_extension, the current code was
checking whether the flags had DSP instruction but the architecture
selected for Tag_CPU_arch did not have any. This was necessary because
extension feature bit were not available separately. This is no longer
necessary and can be simplified.
=== Patch description ===
The patch change the logic to set Tag_DSP_extension to check whether any
DSP feature bit is set in the extension feature bit, as per the
definition of that build attribute. The patch also removes all
definitions of arm_arch which is now unneeded.

[ARM] Keep separation between extensions and architecture bits throughout execution
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to keep the distinction between
architecture feature bits and extension ones after parsing has occured.
=== Motivation ===
This distinction is necessary to allow the Tag_CPU_arch build attribute
value to be exactly as per the architecture of the selected CPU. With
mixed architecture and extension feature bit, it is impossible to find
an architecture with an exact match of feature bit and the build
attribute value logic must then select the closest match which might not
be the right architecture. The previous patch in the patch series makes
the distinction possible when parsing -mcpu and .cpu directives but the
distinction gets lost after. Similarly feature bits contributed by
extensions in -march or .arch_extensions directive are mixed together
with architecture extensions.
=== Patch description ===
The patch adds new feature bit pointer for extension feature bits.
Information from the parsing regarding extensions can then be kept
separate in those. This requires adapting arm_parse_extension to deal
with two feature bits, allowing the architecture bits to be marked as
const. It also requires extra care when setting cpu_variant and
selected_cpu because the extension bits are optional since there might
not be any extension in use.
Note that contrary to cpu feature bits, the extension feature bits are
made read/write and are always dynamically allocated. This allows to
unconditionally free them in arm_md_post_relax added for this occasion,
thereby fixing a longstanding memory leak when arm_parse_extension was
invoked (XNEW of ext_fset without corresponding XDELETE).
Introduction of arm_md_post_relax is necessary to only free the
extension feature bits after aeabi_set_attribute_string has been called
for the last time.

[ARM] Separate extensions from architectures in arm_cpus
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to distinguish for a CPU the feature bits
coming from its architecture from the feature bits coming from
extension(s) available in this CPU.
=== Motivation ===
This distinction is necessary to allow the Tag_CPU_arch build attribute
value to be exactly as per the architecture of the selected CPU. With
mixed architecture and extension feature bit, it is impossible to find
an architecture with an exact match of feature bit and the build
attribute value logic must then select the closest match which might not

=== Patch description ===
The patch creates a new field in the arm_cpus table to hold the feature
set for the extensions available in each CPU. The existing architecture
feature set is then updated to remove those feature bit. The patch also
takes advantage of all the lines being changed to reindent the whole
table.
Note: This patch *adds* a memory leak due to mcpu_cpu_opt sometimes
pointing to dynamically allocated feature bits which is never freeed.
The subsequent patch in the series solves this issue as well as a
preexisting identical issue in arm_parse_extension. The patches are kept

Use '::iterator' instead of '::const_iterator' on environ.c (and fix breakage on early versions of libstdc++)
Even though C++11 supports modifying containers using a const_iterator
(e.g., calling the 'erase' method of a std::vector), early versions of
libstdc++ did not implement that. Some of our buildslaves are using
these versions (e.g., the AArch64 buildslave uses gcc 4.8.8), and my
previous commit causes a breakage on them. The solution is simple:
just use a normal iterator, without const.

C++ify gdb/common/environ.c
As part of the preparation necessary for my upcoming task, I'd like to
propose that we turn gdb_environ into a class. The approach taken
here is simple: the class gdb_environ contains everything that is
needed to manipulate the environment variables. These variables are
stored in an std::vector<char *>, which can be converted to a 'char
**' and passed as argument to functions that need it.
The usage has not changed much. As per Pedro's suggestion, this class
uses a static factory method initialization. This means that when an
instance is created, it is initially empty. When needed, it has to be
initialized using the static method 'from_host_environ'.
As mentioned before, this is a preparation for an upcoming work that I
will be posting in the next few weeks or so. For that work, I'll
probably create another data structure that will contain all the
environment variables that were set by the user using the 'set
environment' command, because I'll need access to them. This will be
much easier with the class-ification of gdb_environ.
As noted, this has been regression-tested with the new version of
environ.exp and no regressions were found.

.gdb_index writer: close the file before unlinking it
We should close the file before unlinking because on MS-Windows one
cannot delete a file that is still open.
I considered making 'gdb::unlinker::unlinker(const char *)'
'noexcept(true)' and then adding
static_assert (noexcept (gdb::unlinker (filename.c_str ())), "");
but that doesn't really work because gdb::unlinker has a gdb_assert,
which can throw a QUIT if/when the assertion fails. 'noexcept(true)'
would cause GDB to abruptly terminate if/when the assertion fails.

On noMMU platforms, the following code gets compiled:
child_stack = xmalloc (STACK_SIZE * 4);
Where child_stack is a gdb_byte*, and xmalloc() returns a void*. While
the lack of cast is valid in C, it is not in C++, causing the
following build failure:
../nat/linux-ptrace.c: In function 'int linux_fork_to_function(gdb_byte*, int (*)(void*))':
../nat/linux-ptrace.c:273:29: error: invalid conversion from 'void*' to 'gdb_byte* {aka unsigned char*}' [-fpermissive]

gdb: Use -Werror when checking for (un)supported warning flags
In warning.m4, we pass all the warning flags one by one to the compiler
to test if they are supported by this particular compiler. If the
compiler exits with an error, we conclude that this warning flag is not
supported and exclude it. This allows us to use warning flags without
having to worry about which versions of which compilers support each
flag.
clang, by default, only emits a warning if an unknown flag is passed:
warning: unknown warning option '-Wfoo' [-Wunknown-warning-option]
The result is that we think that all the warning flags we use are
supported by clang (they are not), and the compilation fails later when
building with -Werror, since the aforementioned warning becomes an
error. The fix is to also pass -Werror when probing for supported
flags, then we'll correctly get an error when using an unknown warning,
and we'll exclude it:
error: unknown warning option '-Wfoo' [-Werror,-Wunknown-warning-option]
I am not sure why there is a change in a random comment in
gdbserver/configure, but I suppose it's a leftfover from a previous
patch, so I included it.

* configure: Re-generate.
* warning.m4: Pass -Werror to compiler when checking for

gdb: Pass -x c++ to the compiler
Because we are compiling .c files containing C++ code, clang++ complains
with:
clang: error: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated
If renaming all the source files to .cpp is out of the question, an
alternative is to pass "-x c++" to convince the compiler that we are
really compiling C++. It works fine with GCC too.

extract/store integer function template
This patch converts functions extract_{unsigned,signed}_integer
to a function template extract_integer, which has two instantiations. It
also does the similar changes to store__{unsigned,signed}_integer,
regcache::raw_read_{unsigned,signed}, regcache::raw_write_{unsigned,signed},
regcache::cooked_read_{unsigned,signed},
regcache::cooked_write_{unsigned,signed}.
This patch was posted here
https://sourceware.org/ml/gdb-patches/2017-05/msg00492.html but the
problem was fixed in a different way. However, I think the patch is still
useful to shorten the code.

Rewrite __start and __stop symbol handling
This arranges for __start and __stop symbols to be defined before
garbage collection, for all target formats. That should allow the
COFF and PE --gc-sections to keep a singleton orphan input section,
a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF
treatment of keeping all input sections associated with a __start or
__stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained.
.startof. and .sizeof. symbols are deliberately not defined before
garbage collection, so these won't affect garbage collection of
sections.
The patch also ensures __start, __stop, .startof. and .sizeof. symbols
are defined before target size_dynamic_sections is called, albeit
with a preliminary value, so that target code doesn't need to cope
with a symbol changing from undefined at size_dynamic_sections to
defined at relocate_section.
Also, a number of problems with the testcases have been fixed.

For some pc-relative relocations we want to allow them under PIC mode while

relocation against such symbol.
SYMBOL_REFERENCES_LOCAL should be used and is more accurate than the original

arc: Select CPU model properly before disassembling
Enforce CPU model for disassembler via its options, if it was specified in XML
target description, otherwise use default method of determining CPU implemented
in disassembler - scanning ELF private header. The latter requires
disassemble_info->section to be properly initialized. To make sure that
info->section is set in all cases this patch partially reverts [1] for ARC: it
reinstates arc_delayed_print_insn as a "print_insn" function for ARC, but
now this function only sets disassemble_info->section and then calls
default_print_insn to do the rest of the job.
Support for CPU in disassembler options for ARC has been added in [2].

[AArch64] Allow COPY relocation elimination
As discussed at the PR, this patch tries to avoid COPY relocation generation
and propagate the original relocation into runtime if it was relocating on
writable section. The ELIMINATE_COPY_RELOCS has been set to true and it's
underlying infrastructure has been improved so that the COPY reloc elimination
at least working on absoluate relocations (ABS64) on AArch64.
BFD linker copy relocation elimination framwork requires the backend to always
allocate dynrelocs for all those relocation types that are possible to introduce
copy relocations. This is for adjust_dynamic_symbol hook to be able to get all
symbol reference information. Should one symbol is referenced by more than one
relocations, if there is any of them needs copy relocation then linker should
generate it.

Don't use print_insn_XXX in GDB
This is a follow-up to
[PATCH 0/6] Unify the disassembler selection in gdb and objdump
https://sourceware.org/ml/binutils/2017-05/msg00192.html
that is, opcodes is able to select the right disassembler, so gdb
doesn't have to select them. Instead, gdb can just use
default_print_insn. As a result, these print_insn_XXX are not used
out of opcodes, so this patch also moves their declarations from
include/dis-asm.h to opcodes/disassemble.h. With this change,
GDB doesn't use any print_insn_XXX directly any more.

Fix register selection in var-access.exp
The new test var-access.exp causes FAILs on i686. This is because the
test chooses the wrong name for DWARF register number 1: It uses
"edx" (which corresponds to DWARF register number 2), but should have used
"ecx" instead.
Also, the current logic in var-access.exp does not correctly distinguish
between a 64-bit and a 32-bit program on an x86-64 target. It uses the
64-bit register names for both.
These problems are fixed. In order to address the latter, the convenience
macros is_*_target are exploited where appropriate.

Introduce gdb::byte_vector, add allocator that default-initializes
In some cases we've been replacing heap-allocated gdb_byte buffers
managed with xmalloc/make_cleanup(xfree) with gdb::vector<gdb_byte>.
That usually pessimizes the code a little bit because std::vector
value-initializes elements (which for gdb_byte means
zero-initialization), while if you're creating a temporary buffer,
you're most certaintly going to fill it in with some data. An
alternative is to use
unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);
but it looks like that's not very popular.
Recently, a use of obstacks in dwarf2read.c was replaced with
std::vector<gdb_byte> and that as well introduced a pessimization for
always memsetting the buffer when it's garanteed that the zeros will
be overwritten immediately. (see dwarf2read.c change in this patch to
find it.)
So here's a different take at addressing this issue "by design":
#1 - Introduce default_init_allocator<T>
I.e., a custom allocator that does default construction using default
initialization, meaning, no more zero initialization. That's the
default_init_allocation<T> class added in this patch.
See "Notes" at
<http://en.cppreference.com/w/cpp/container/vector/resize>.
#2 - Introduce def_vector<T>
I.e., a convenience typedef, because typing the allocator is annoying:
using def_vector<T> = std::vector<T, gdb::default_init_allocator<T>>;
#3 - Introduce byte_vector
Because gdb_byte vectors will be the common thing, add a convenience
"byte_vector" typedef:
using byte_vector = def_vector<gdb_byte>;
which is really the same as:
std::vector<gdb_byte, gdb::default_init_allocator<gdb_byte>>;
The intent then is to make "gdb::byte_vector" be the go-to for dynamic
byte buffers. So the less friction, the better.
#4 - Adjust current code to use it.
To set the example going forward. Replace std::vector uses and also
unique_ptr<byte[]> uses.
One nice thing is that with this allocator, for changes like these:
-std::unique_ptr<byte[]> buf (new gdb_byte[some_size]);
+gdb::byte_vector buf (some_size);
fill_with_data (buf.data (), buf.size ());
the generated code is the same as before. I.e., the compiler
de-structures the vector and gets rid of the unused "reserved vs size"
related fields.
The other nice thing is that it's easier to write
gdb::byte_vector buf (size);
than
std::unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);
or even (C++14):
auto buf = std::make_unique<gdb_byte[]> (size); // zero-initializes...
#5 - Suggest s/std::vector<gdb_byte>/gdb::byte_vector/ going forward.
Note that this commit actually fixes a couple of bugs where the current
code is incorrectly using "std::vector::reserve(new_size)" and then
accessing the vector's internal buffer beyond the vector's size: see
dwarf2loc.c and charset.c. That's undefined behavior and may trigger
debug mode assertion failures. With default_init_allocator,
"resize()" behaves like "reserve()" performance wise, in that it
leaves new elements with unspecified values, but, it does that safely
without triggering undefined behavior when you access those values.

Always define referenced __start_SECNAME/__stop_SECNAME
Currently, linker will define __start_SECNAME and __stop_SECNAME symbols
only for orphaned sections.
However, during garbage collection, ELF linker marks all sections with
references to __start_SECNAME and __stop_SECNAME symbols as used even
when section SECNAME isn't an orphaned section and linker won't define
__start_SECNAME nor __stop_SECNAME. And ELF linker stores the first
input section whose name matches __start_SECNAME or __stop_SECNAME in
u.undef.section for garbage collection. If these symbols are provided
in linker script, u.undef.section is set to the section where they will
defined by linker script, which leads to the incorrect output.
This patch changes linker to always define referenced __start_SECNAME and
__stop_SECNAME if the input section name is the same as the output section
name, which is always true for orphaned sections, and SECNAME is a C
identifier. Also __start_SECNAME and __stop_SECNAME symbols are marked
as hidden by ELF linker so that __start_SECNAME and __stop_SECNAME symbols
for section SECNAME in different modules are unique. For garbage
collection, ELF linker stores the first matched input section in the
unused vtable field.

Fix bit-/byte-offset mismatch in parameter to read_value_memory
The function read_value_memory accepts a parameter embedded_offset and

read/write_pieced_value: Improve logic for buffer allocation
So far the main loop in read_pieced_value and write_pieced_value is
structured like this:
(1) Prepare a buffer and some variables we may need;
(2) depending on the DWARF piece type to be handled, use the buffer and
the prepared variables, ignore them, or even recalculate them.
This approach reduces readability and may also lead to unnecessary copying
of data. This patch moves the preparations to the places where sufficient
information is available and removes some of the variables involved.

Fix handling of DWARF register pieces on big-endian targets
For big-endian targets the logic in read/write_pieced_value tries to take
a register piece from the LSB end. This requires offsets and sizes to be
adjusted accordingly, and that's where the current implementation has some
issues:
* The formulas for recalculating the bit- and byte-offsets into the
register are wrong. They just happen to yield correct results if
everything is byte-aligned and the piece's last byte belongs to the
given value.
* After recalculating the bit offset into the register, the number of
bytes to be copied from the register is not recalculated. Of course
this does not matter if everything (particularly the piece size) is
byte-aligned.
These issues are fixed. The size calculation is performed with a new
helper function bits_to_bytes().

write_pieced_value: Transfer least significant bits into bit-field
On big-endian targets, when targeting a bit-field, write_pieced_value
currently transfers the source value's *most* significant bits to the
target value, instead of its least significant bits. This is fixed.
In particular the fix adjusts the initial value of 'offset', which can now
potentially be nonzero. Thus the variable 'type_len' is renamed to
'max_offset', to avoid confusion. And for consistency, the affected logic
that was mirrored in read_pieced_value is changed there in the same way.

read/write_pieced_value: Respect value parent's offset
In the case of targeting a bit-field, read_pieced_value and
write_pieced_value calculate the number of bits preceding the bit-field
without considering the relative offset of the value's parent. This is
relevant for a structure variable like this:
struct s {
uint64_t foo;
struct {
uint32_t bar;
uint32_t bf : 10; /* <-- target bit-field */
} baz;
} s;
In this scenario, if 'val' is a GDB value representing s.baz.bf,
val->parent represents the whole s.baz structure, and the following holds:
- value_offset (val) == sizeof s.baz.bar == 4
- value_offset (val->parent) == sizeof s.foo == 8
The current logic would only use value_offset(val), resulting in the wrong
offset into the target value. This is fixed.

* dwarf2loc.c (read_pieced_value): Respect parent value's offset
when targeting a bit-field.

PR gdb/21226: Take DWARF stack value pieces from LSB end
When taking a DW_OP_piece or DW_OP_bit_piece from a DW_OP_stack_value, the
existing logic always takes the piece from the lowest-addressed end, which
is wrong on big-endian targets. The DWARF standard states that the
"DW_OP_bit_piece operation describes a sequence of bits using the least
significant bits of that value", and this also matches the current logic
in GCC. For instance, the GCC guality test case pr54970.c fails on s390x
because of this.
This fix adjusts the piece accordingly on big-endian targets. It is
assumed that:
* DW_OP_piece shall take the piece from the LSB end as well;
* pieces reaching outside the stack value bits are considered undefined,
and a zero value can be used instead.

write_pieced_value: Fix size capping logic
A field f in a structure composed of DWARF pieces may be located in
multiple pieces, where the first and last of those may contain bits from
other fields as well. So when writing to f, the beginning of the first
and the end of the last of those pieces may have to be skipped. But the
logic in write_pieced_value for handling one of those pieces is flawed
when the first and last piece are the same, i.e., f is contained in a
single piece:
< - - - - - - - - - piece_size - - - - - - - - - ->
+-------------------------------------------------+
| skipped_bits | f_bits | / / / / / / / / / / |
+-------------------------------------------------+
The current logic determines the size of the sub-piece to operate on by
limiting the piece size to the bit size of f and then subtracting the
skipped bits:
min (piece_size, f_bits) - skipped_bits
Instead of:
min (piece_size - skipped_bits, f_bits)
So the resulting sub-piece size is corrupted, leading to wrong handling of
this piece in write_pieced_value.
Note that the same bug was already found in read_pieced_value and fixed
there (but not in write_pieced_value), see PR 15391.
This patch swaps the calculations, bringing them into the same (correct)
order as in read_pieced_value.

Remove val_print_type_code_int
Now that print_scalar_formatted is more capable, there's no need for
val_print_type_code_int. This patch removes it in favor of
val_print_scalar_formatted.

Simplify print_scalar_formatted
This unifies the two switches in print_scalar_formatted, removing some
now-redundant code. Now scalar types are never converted to LONGEST,
instead printing is done using print_*_chars, operating on the byte
representation.

mips-tdep.c: Remove MAX_REGISTER_SIZE usage
mips_eabi_push_dummy_call is storing the address of a struct in a
buffer that must have the same of the confisued/set ABI register size.
Add a define for the maximum ABI size and use it to size the local
buffer. Also rename the 'regsize' local to 'abi_regsize' for clarity.

.gdb_index prod perf regression: mapped_symtab now vector of values
... instead of vector of pointers
There's no real reason for having mapped_symtab::data be a vector of
heap-allocated symtab_index_entries. symtab_index_entries is not that
large, it's movable, and it's cheap to move. Making the vector hold
values instead improves cache locality and eliminates many roundtrips
to the heap.
Using the same test as in the previous patch, against the same gdb
inferior, timing improves ~13% further:
~6.0s => ~5.2s (average of 5 runs).
Note that before the .gdb_index C++ifycation patch, we were at ~5.7s.
We're now consistenly better than before.

.gdb_index prod perf regression: Estimate size of psyms_seen
Using the same test as the previous patch, perf shows GDB spending
over 7% in "free". A substantial number of those calls comes from
insertions in the psyms_seen unordered_set causing lots of rehashing
and recreating buckets. Fix this by computing an estimate of the size
of the set upfront.
Using the same test as in the previous patch, against the same gdb

.gdb_index prod perf regression: find before insert in unordered_map
"perf" shows the unordered_map::emplace call in write_hash_table a bit
high up on profiles. Fix this using the find + insert idiom instead
of going straight to insert.
I tried doing the same to the other unordered_maps::emplace calls in
the file, but saw no performance improvement, so left them be.
With a '-g3 -O2' build of gdb, and:
$ cat save-index.cmd
set $i = 0
while $i < 100
save gdb-index .
set $i = $i + 1
end
$ time ./gdb -data-directory=data-directory -nx --batch -q -x save-index.cmd ./gdb.pristine

Introduce "set debug separate-debug-file"
I helped someone figure out why their separate debug info (debug
link-based) was not found by gdb. It turns out that the debug file was
not named properly. It made me realize that it is quite difficult to
diagnose this kind of problems. This patch adds some debug output to
show where GDB looks for those files, so that it should be (more)
obvious to find what's wrong.
Here's an example of the result, first with an example of unsuccessful lookup,
and then a successful one.

gdbarch: Remove displaced_step_free_closure
The displaced_step_free_closure gdbarch hook allows architectures to
free data they might have allocated to complete a displaced step.
However, all architectures using that hook use the
simple_displaced_step_free_closure provided in arch-utils.{c,h}, which
does a simple xfree. We can remove it and do an xfree directly instead
of calling the hook.

Include <signal.h> on gdbserver/fork-child.c (and fix regressions)
Hi,
This is another obvious patch that fixes a thinko from my previous
startup-with-shell series. We should conditionally include <signal.h>
on gdb/gdbserver/fork-child.c because gdbserver will be putting the
inferior's terminal on the correct mode after the call to
fork_inferior, and for that it needs to ignore SIGTTOU.
This patch fixes a bunch of regressions happening on AArch64 that were
reported by Yao.

Fix possible bug when no args have been provided to the executable
Hi,
This bug is related to:
<https://sourceware.org/ml/gdb-patches/2017-06/msg00216.html>
On stringify_argv, we have to check if args[0] is not NULL before
stringifying anything, otherwise we might do the wrong thing when
trimming the "ret" string in the end. args[0] will be NULL when no
arguments are passed to the inferior that will be started.

[ARC] Corrected conditions for dynamic sections creation.
Fixed conditions to create the dynamic sections.
Previously there would be times where the dynamic sections would not be created
although they were actually required for linking to work.
Issue found through OpenADK build, more precisely the ublicb testsuite package.

[ARC] Fixed condition to generate TEXTREL.
TEXTREL was being generated even when relocatable .o files had the .rela.text
section. Now it is limitted only to dynamic object files that still have them.
Nevertheless, our target aborts in those cases due to architecture limitations
where icache is not coherent with dcache, and to force this coherence expensive
kernel level support would be needed.

[ARC] Fixed TLS for IE model.
In the case of static relocation, the GOT entries are fixed at link time
and are set by the linker.
In order to compute the right TLS offset it is necessary to add TCB_SIZE
to the offset, just in case the dynamic linker is not expected to be
executed (static linked case).
This problem does appear in dynamic linked applications, as the dynamic
linker is adding this TCB_SIZE by operating the TCB block structure.
Problem revealed in GLIBC with static linking.

[ARC] Don't convert _DYNAMIC@ to _GLOBAL_OFFSET_TABLE_
Historically the arc abi demanded that a GOT[0] should be referencible as
[pc+_DYNAMIC@gotpc]. Hence we convert a _DYNAMIC@gotpc to a GOTPC reference to
_GLOBAL_OFFSET_TABLE_.
This is no longer the case and uClibc and upcomming GNU libc don't expect this
to happen.

[bfd][arm] Don't assert on suspicious build attributes in input file
It's generally a bad idea to use assertions to validate our idea of
what an input file looks like. We need to be as liberal as possible
in what we accept with respect to standards and conservative with what
we produce.
Currently, if gcc is used to produce an assembler file which contains
only data, but the FPU is set to fpv4-sp-d16 and mfloat-abi=hard, then
the following attributes will be set in the output:
.cpu arm7tdmi
.eabi_attribute 27, 1 @ Tag_ABI_HardFP_use
.eabi_attribute 28, 1 @ Tag_ABI_VFP_args
.eabi_attribute 20, 1 @ Tag_ABI_FP_denormal
.eabi_attribute 21, 1 @ Tag_ABI_FP_exceptions
.eabi_attribute 23, 3 @ Tag_ABI_FP_number_model
.eabi_attribute 24, 1 @ Tag_ABI_align8_needed
.eabi_attribute 25, 1 @ Tag_ABI_align8_preserved
.eabi_attribute 26, 2 @ Tag_ABI_enum_size
.eabi_attribute 30, 6 @ Tag_ABI_optimization_goals
.eabi_attribute 34, 0 @ Tag_CPU_unaligned_access
.eabi_attribute 18, 4 @ Tag_ABI_PCS_wchar_t
There is then no .fpu directive to cause Tag_FP_arch to be set,
because there are no functions containing code in the object file. If
this object file is assembled by hand, but without -mfpu on the
invocation of the assembler, then the build attributes produced will
trigger an assertion during linking.
Thinking about the build attributes, the combination of a
single-precision only implementation of no floating-point architecture
is still no floating-point architecture. Hence the assertion on the
input BFD in the linker makes no real sense.
We should, however, be more conservative in what we generate, so I've
left the assertion on the output bfd in place; I don't think we can
trigger it with this change since we never merge the problematic tags
from a perversely generated input file.
* elf32-arm.c (elf32_arm_merge_eabi_attributes): Remove assertion
that the input bfd has Tag_FP_ARCH non-zero if Tag_ABI_HardFP_use
is non-zero. Add clarifying comments.

Implement proper "startup-with-shell" support on gdbserver
This patch implements the proper support for the "startup-with-shell"
feature on gdbserver. A new packet is added, QStartupWithShell, and
it is sent on initialization. If the host sends a
"QStartupWithShell:1", it means the inferior shall be started using a
shell. If the host sends a "QStartupWithShell:0", it means the
inferior shall be started without using a shell. Any other value is
considered an error.
There is no way to remotely set the shell that will be used by the
target to start the inferior. In order to do that, the user must
start gdbserver while providing a shell via the $SHELL environment
variable. The same is true for the host side.
The "set startup-with-shell" setting from the host side is used to
decide whether to start the remote inferior using a shell. This same
setting is also used to decide whether to use a shell to start the
host inferior; this means that it is not really possible to start the
inferior using different mechanisms on target and host.
A documentation patch is included, along with a new testcase for the
feature.

Share fork_inferior et al with gdbserver
This is the most important (and the biggest, sorry) patch of the
series. It moves fork_inferior from gdb/fork-child.c to
nat/fork-inferior.c and makes all the necessary adjustments to both
GDB and gdbserver to make sure everything works OK.
There is no "most important change" with this patch; all changes are
made in a progressive way, making sure that gdbserver had the
necessary features while not breaking GDB at the same time.
I decided to go ahead and implement a partial support for starting the
inferior with a shell on gdbserver, although the full feature comes in
the next patch. The user won't have the option to disable the
startup-with-shell, and also won't be able to change which shell
gdbserver will use (other than setting the $SHELL environment
variable, that is).
Everything is working as expected, and no regressions were present
during the tests.

Move parts of inferior job control to common/
This commit moves a few bits responsible for dealing with inferior job
control from GDB to common/, which makes them available to gdbserver.
This is necessary for the upcoming patches that will share
fork_inferior et al between GDB and gdbserver.
We move some parts of gdb/terminal.h to gdb/common/common-terminal.h,
especifically the code that checks terminal features and that are used
to set job_control accordingly.
After sharing parts of gdb/terminal.h, we also to share the two
functions on gdb/inflow.c that are going to be needed by the
fork_inferior rework. They are 'gdb_setpgid' and the new
'have_job_control'. I've also taken the opportunity to give a more
meaningful name to "inflow.c" on common/. Now it is called

[Patch, ARM] Relax the restrictions on REG_SP under Thumb mode on ARMv8-A
For Thumb mode, since ARMv8-A, REG_SP is allowed in most of the places in
Rd/Rt/Rt2 etc while it was disallowed before ARMv8-A, and was rejected through
the "reject_bad_reg" macro and several scattered checks.
This patch only rejects REG_SP in "reject_bad_reg" and several related places
for legacy architectures before ARMv8-A. I have checked those affected instructions
, all of them qualify such relaxations.
Testcases adjusted accordingly.
* ld-sp-warn.d was written without .arch and without -march options passed.
By default it assumes all architectures, so I deleted the REG_SP warning
on ldrsb as it's supported on ARMv8-A. There are actually quite a few
seperate tests on other architectures, for example ld-sp-warn-v7.l etc.,
so there the test for ldrsb on legacy architectures are still covered.
* sp-pc-validations-bad-t has been extended to armv8-a.
* strex-bad-t.d restricted on armv7-a.
* Some new tests for REG_SP used as Rd/Rt etc added in sp-usage-thumb2-relax*.

ld: Allow section groups to be resolved as part of a relocatable link
This commit adds a new linker feature: the ability to resolve section
groups as part of a relocatable link.
Currently section groups are automatically resolved when performing a
final link, and are carried through when performing a relocatable link.
By carried through this means that one copy of each section group (from
all the copies that might be found in all the input files) is placed
into the output file. Sections that are part of a section group will
not match input section specifiers within a linker script and are
forcibly kept as separate sections.
There is a slight resemblance between section groups and common
section. Like section groups, common sections are carried through when
performing a relocatable link, and resolved (allocated actual space)
only at final link time.
However, with common sections there is an ability to force the linker to
allocate space for the common sections when performing a relocatable
link, there's currently no such ability for section groups.
This commit adds such a mechanism. This new facility can be accessed in
two ways, first there's a command line switch --force-group-allocation,
second, there's a new linker script command FORCE_GROUP_ALLOCATION. If
one of these is used when performing a relocatable link then the linker
will resolve the section groups as though it were performing a final
link, the section group will be deleted, and the members of the group
will be placed like normal input sections. If there are multiple copies
of the group (from multiple input files) then only one copy of the group
members will be placed, the duplicate copies will be discarded.
Unlike common sections that have the --no-define-common command line
flag, and INHIBIT_COMMON_ALLOCATION linker script command there is no
way to prevent group resolution during a final link, this is because the
ELF gABI specifically prohibits the presence of SHT_GROUP sections in a
fully linked executable. However, the code as written should make
adding such a feature trivial, setting the new resolve_section_groups
flag to false during a final link should work as you'd expect.

ELF/BFD: Hold the number of internal static relocs in `->reloc_count'
Correct a commit e5713223cbc1 ("MIPS/BFD: For n64 hold the number of
internal relocs in `->reloc_count'") regression and change internal
relocation handling in the generic ELF BFD linker code such that, except
in the presence of R_SPARC_OLO10 relocations, a section's `reloc_count'
holds the number of internal rather than external relocations, making
the handling more consistent between GAS, which sets `->reloc_count'
with a call to `bfd_set_reloc', and LD, which sets `->reloc_count' as it
reads input sections.
The handling of dynamic relocations remains unchanged and they continue
holding the number of external relocations in `->reloc_count'; they are
also not converted to the internal form except in `elf_link_sort_relocs'
(which does not handle the general, i.e. non-n64-MIPS case of composed
relocations correctly as per the ELF gABI, though it does not seem to
matter for the targets we currently support).
The n64 MIPS backend is the only one with `int_rels_per_ext_rel' set to
non-one, and consequently the change is trivial for all the remaining
backends and targets.

C++ify breakpoint class hierarchy (destructors only)
Breakpoints are currently in a limbo state between C and C++. There is
a pseudo class hierarchy implemented using struct fields. Taking
watchpoint as an example:
struct watchpoint
{
/* The base class. */
struct breakpoint base;
...
}
and it is instantianted with "new watchpoint ()". When destroyed, a
destructor is first invoked through the breakpoint_ops, and then the
memory is freed by calling delete through a pointer to breakpoint.
Address sanitizer complains about this, for example, because we new and
delete the same memory using different types.
This patch takes the logical step of making breakpoint subclasses extend
the breakpoint class for real, and converts their destructors to actual
C++ destructors.
Regtested on the buildbot.

commit 3b0871f44a3402f4e1e811ae81c8ba1293c1c7be

Create struct type for longjmp breakpoint
The longjmp kind of breakpoint has a destructor, but doesn't have an
associated structure. The next patch converts breakpoint destructors from
breakpoint_ops::dtor to actual destructors, but to do that it is needed
for longjmp_breakpoint to have a structure that will contain such
destructor. This patch adds it.
According to initialize_breakpoint_ops, a longjmp breakpoint derives
from "momentary breakpoints", so eventually a momentary_breakpoint
struct/class should probably be created. It's not necessary for the
destructor though, so a structure type for this abstract kind of
breakpoint can be added when we fully convert breakpoint ops into
methods of the breakpoint type hierarchy.
It is now necessary to instantiate different kinds of breakpoint objects
in set_raw_breakpoint_without_location based on bptype (sometimes a
breakpoint, sometimes a longjmp_breakpoint), so it now uses
new_breakpoint_from_type to do that. I also changed set_raw_breakpoint
to use it, even though I don't think that it can ever receive a bptype
that actually requires it. However, I think it's good if all breakpoint
object instantion is done in a single place.

(is_tracepoint_type): Change return type to bool.
(is_longjmp_type): New function.
(new_breakpoint_from_type): Handle longjmp kinds of breakpoints.

Introduce and use new_breakpoint_from_type

Use the ELF class to determine the word size for FreeBSD core notes.
FreeBSD ELF cores contain data structures with that have two different
layouts: one for ILP32 platforms and a second for LP64 platforms.
Previously, the code used 'bits_per_word' from 'arch_info', but this
field is not a reliable indicator of the format for FreeBSD MIPS cores
in particular.
I had originally posted this patch back in November because process
cores for FreeBSD MIPS contained an e_flags value of 0 in the header
which resulted in a bfd_arch which always had 'bits_per_word' set to
32. This permitted reading o32 cores, but not n64 cores. The feedback
I received then was to try to change n64 cores to use a different
default bfd_arch that had a 64-bit 'bits_per_word' when e_flags was zero.
I submitted a patch to that effect but it was never approved. Instead,
I changed FreeBSD's kernel and gcore commands to preserve the e_flags
field from an executable when generating process cores. With a proper
e_flags field in process cores, n64 cores now use a 64-bit bfd_arch and
now work fine. However, the change to include e_flags in the process
cores had the unintended side effect of breaking handling of o32
process cores. Specifically, FreeBSD MIPS builds o32 with a default
MIPS architecture of 'mips3', thus FreeBSD process cores with a non-zero
e_flags match the 'mips3' bfd_arch which has 64 'bits_per_word'.
From this, it seems that 'bits_per_word' for FreeBSD MIPS is not likely
to ever be completely correct. However, FreeBSD core dumps do
reliably set the ELF class to ELFCLASS32 for cores using ILP32 and
ELFCLASS64 for cores using LP64. As such, I think my original patch of
using the ELF class instead of 'bits_per_word' is probably the simplest
and most reliable approach for detecting the note structure layout.

PPC64_OPT_LOCALENTRY
ELFv2 functions with localentry:0 are those with a single entry point,
ie. global entry == local entry, and that have no requirement on r2 or
r12, and guarantee r2 is unchanged on return. Such an external
function can be called via the PLT without saving r2 or restoring it
on return, avoiding a common load-hit-store for small functions. The
optimization is attractive. The TOC pointer load-hit-store is a major
reason why calls to small functions that need no register saves, or
with shrink-wrap, no register saves on a fast path, are slow on
powerpc64le.
To be safe, this optimization needs ld.so support to check that the
run-time matches link-time function implementation. If a function
in a shared library with st_other localentry non-zero is called
without saving and restoring r2, r2 will be trashed on return, leading
to segfaults. For that reason the optimization does not happen for
weak functions since a weak definition is a fairly solid hint that the
function will likely be overridden. I'm also not enabling the
optimization by default unless glibc-2.26 is detected, which should
have the ld.so checks implemented.

Later CPU generations added optional operands to the ipte/idte

supported the optional operands only with the specific hardware

Regression-tested with on s390 and s390x. Committed to mainline.

[ARC] Allow CPU to be enforced via disassemble_info options
Currently print_insn_arc relies on BFD mach and ELF private headers to
distinguish between various ARC architectures. Sometimes those values are not
correct or available, mainly in the case of debugging targets without and ELF
file available. Changing a BFD mach is not a problem for the debugger, because
this is a generic BFD field, and GDB, for example, already sets it according to
information provided in XML target description or specified via GDB 'set arch'
command. However, things are more complicated for ELF private headers, since
it requires existing of an actual ELF file. To workaround this problem this
patch allows CPU model to be specified via disassemble info options. If CPU is
specified in options, then it will take a higher precedence than whatever might
be specified in ELF file.
This is mostly needed for ARC EM and ARC HS, because they have the same
"architecture" (mach) ARCv2 and differ in their private ELF headers. Other ARC
architectures can be distinguished between each other purely via "mach" field.
Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid
ARC CPU name as supported by GAS. Note that this creates a seeming redundancy
with objdump -m/--architecture option, however -mEM and -mHS still result in
"ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual
effect on disassembler.

[ARC] Add arc-cpu.def with processor definitions
This patch extracts ARC CPU definitions from gas/config/tc-arc.c (cpu_types)
into a separate file arc-cpu.def. This will allow reuse of CPU type definition
in multiple places where it might be needed, for example in disassembler. This
will help ensure that gas and disassembker use same option values for CPUs.
arc-cpu.def file relies on preprocessor macroses which are defined somewhere
else. This for example multiple C files to include arc-cpu.def, but define
different macroses, therefore creating different structures.

[ARC] Implement compatible function for ARC BFD architectures
The general rule for bfd_arch_info_type->compatible (A, B) is that if A and B
are compatible, then this function should return architecture that is more
"feature-rich", that is, can run both A and B. ARCv2, EM and HS all has same
mach number, so bfd_default_compatible assumes they are the same, and returns
an A. That causes issues with GDB, because GDB assumes that if machines are
compatible, then "compatible ()" always returns same machine regardless of
argument order. As a result GDB gets confused because, for example,
compatible(ARCv2, EM) returns ARCv2, but compatible(EM, ARCv2) returns EM,
hence GDB is not sure if they are compatible and prints a warning.

So far we only had an instruction flag which made an arbitrary number

allowing 2 optional arguments. Hopefully we won't need more than that
in the future. So far there will be only a single use of optparm2.

Add unit test to gdbarch methods register_to_value and value_to_register
This patch adds one unit test for gdbarch methods register_to_value and
value_to_register. The test pass different combinations of {regnu, type}
to gdbarch_register_to_value and gdbarch_value_to_register. In order
to do the test, add a new function create_new_frame to create a fake
frame. It can be improved after we converted frame_info to class.
In order to isolate regcache (from target_ops operations on writing
registers, like target_store_registers), the sub-class of regcache in the
test override raw_write. Also, in order to get the right regcache from
get_thread_arch_aspace_regcache, the sub-class of regcache inserts itself
to current_regcache.

Restrict alpha_convert_register_p
This patch restricts alpha_convert_register_p from
"TYPE_LENGTH (type) != 8" to "TYPE_LENGTH (type) == 4", because,
- we have check "TYPE_LENGTH (valtype) == 4" in alpha_register_to_value
and alpha_value_to_register,
- alpha lds and sts instruction access 4 bytes,
- comments "It might need to convert the [float] register into the
corresponding [integer] type (see Alpha)" and integer is 4-byte on
alpha,
I think it is the right restrict condition to "TYPE_LENGTH (valtype) == 4".

Use disassemble.c:disassembler select rs6000 disassembler
Nowadays, rs6000 disassembler is selected in different ways in

opcodes:
case bfd_arch_rs6000:

Use disassemble.c:disassembler select h8300 disassembler
opcodes/disassble.c:disassembler select h8300 disassembler like this,
if (mach == bfd_mach_h8300h || mach == bfd_mach_h8300hn)
disassemble = print_insn_h8300h;
else if (mach == bfd_mach_h8300s

disassemble = print_insn_h8300s;
else

which is the same as what gdb/h8300-tdpe.c does,

Delegate opcodes to select disassembler in GDB
This patch changes GDB to use disassembler selected by opcodes in
default, so that we don't have to duplicate the selection logic again
in GDB side. For example, gdb/score-tdep.c has
static int
score_print_insn (bfd_vma memaddr, struct disassemble_info *info)
{
if (info->endian == BFD_ENDIAN_BIG)
return print_insn_big_score (memaddr, info);
else
return print_insn_little_score (memaddr, info);
}
and opcodes/disassemble.c has the same logic,
case bfd_arch_score:
if (big)
disassemble = print_insn_big_score;
else
disassemble = print_insn_little_score;
This patch removes the logic in GDB and calls
opcodes/disassemble.c:disassembler in default to select disassembler.

Refactor disassembler selection
Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only. However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd. This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).

Cleanups to FreeBSD/mips native register operations.
Compare against the "raw" PC register number instead of the cooked
register number when determining if a register was handled by
PT_GETREGS. Previously the register fetch/store operations only tried
PT_GETREGS to fetch any individual register. The result was that
fetching or storing an individual register not covered by PT_GETREGS
(such as floating point registers) did not work.
While here, remove an early exit to simplify the code flow from the
PT_GETREGS / PT_SETREGS case, and add a getfpregs_supplies similar to
getregs_supplies to describe the registers supplied by PT_GETFPREGS
and PT_SETFPREGS.

gdb: Document vMustReplyEmpty remote packet
Add mention of the vMustReplyEmpty to the remote serial protocol
documentation. It is important that this packet be treated in the same
fashion as any other unknown 'v' packet, and I have tried to reflect
this in the description of the packet, it is not simply the case that we
_must_ return the empty string for this packet.
As the intention is that we should treat this packet as unknown then an
argument could be made that we should not document it, however, for
someone implementing a gdbserver from scratch, seeing an undocumented
packet arrive from gdb is confusing, and will probably cause them to
have to read the code in order to check how this packet should be
handled, which is not ideal.

Print Rust unsized array types a bit more nicely
It's a bit difficult to create an unsized array type in Rust, but if
you do, right now ptype will show something like "[u8; ]". It really
should print "[u8]", though, which is what this patch implements.
This is part of PR 21466.
Built and regtested on x86-64 Fedora 25. I'm checking this in.

binutils: remove sparc64/mips64 workaround in objcopy build notes merge code
This patch removes a workaround recently installed in objcopy that
avoided removing duplicated notes in targets for which the number of
internal relocations may be bigger than the number of external
relocations. With the recent fixes in sparc64 and mips64, this
workaround is no longer necessary.

Use watchpoint's language when re-parsing expression
PR rust/21484 notes that watch -location does not work with Rust:
(gdb) watch -location a
syntax error in expression, near `) 0x00007fffffffe0f4'.
update_watchpoint tries to tell gdb that the new expression it creates
has C syntax:
/* The above expression is in C. */
b->language = language_c;
However, update_watchpoint doesn't actually use this language when
re-parsing the expression.
Originally I was going to fix this by saving and restoring the
language in update_watchpoint, but this regressed
gdb.dlang/watch-loc.exp, because the constructed expression actually
has D syntax (specifically the name is not parseable by C).
Next I looked at directly constructing an expression, and not relying
on the parser at all; but it seemed to me that upon a re-set, we'd
want to reparse the type, and there is no existing API to do this
correctly.
So, in the end I made a hook to let each language choose what
expression to use. I made all the languages other than Rust use the C
expression, because that is the status quo ante. However, this is
probably not truly correct. After this patch, at least, it is easy to
correct by someone who knows the language(s) in question.
Regtested by the buildbot.

MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count'
Revert parts of commit fee24f1c5bfe ("objdump improvements for mips
elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and
make the `->reloc_count' member of `struct bfd_section' hold the actual
number of internal relocations stored in its `->relocation' vector. To
do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count'
to the actual number of internal relocations retrieved and discard
`mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc'
and their corresponding target macros. Contrary to the description of
`mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes
generic relocation processing code happy and satisfies the "merge notes
section" binutils test case.
Add extra binutils test cases to expand the coverage of the generic
"merge notes section" test case, now passing with the n64 ABI, across
the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in
target configuration, and also to verify correctness of the relocations
produced. Conversely, do not provide any additional test cases for the
original issue addressed with the commit referred:
- objdump would display only 1/3 of the total number of relocations,
because it used the external relocation count, but each external
relocation is brought in as 3 internal relocations.
as n64 ABI relocation processing with `objdump -r' and `objdump -R' is
already widely covered across the GAS and LD test suites.

gdb: fix TYPE_CODE_ARRAY handling in sparc targets
gdb has a special type (TYPE_CODE_ARRAY) to support the gcc extension
(https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html).
TYPE_CODE_ARRAY is handled incorrectly for both (32- and 64-bit) modes
on Sparc machines.
Tested on sparc64-linux-gnu and sparc-solaris (32- and 64-bit mode).
6 tests ( from gdb/testsuite/gdb.base/gnu_vector.exp) failed on
sparc64-Linux and on sparc-Solaris in 32- and 64-bit mode. Now all
these tests passed. gdb/testsuite/gdb.base/gnu_vector.exp has 117
different cases for small (and not small) arrays and structures.
No regressions.

garbage collect debug sections when no alloc sections are kept
The pr20882 testcase fails on a number of targets that add attribute
or note sections to object files, and the default linker script says
those sections should be kept. This patch changes --gc-sections to
drop debug and special sections like .comment when no SEC_ALLOC
section in an object file is kept. The assumption is that debug
sections are describing code and data that will become part of the
final image in memory.
* elflink.c (_bfd_elf_gc_mark_extra_sections): Don't keep
debug and special sections when no non-note alloc sections in an

Fix test failure with Rust 1.18 and 1.19
With Rust 1.18 and 1.19, I saw some test suite failures. They were
all of the same form -- Box seems to be qualified in the output now,
like:
print box_some
$64 = core::option::Option<alloc::boxed::Box<u8>>::Some(0x7ffff6c21018 "\001\000")
... where the test was expecting Option<Box<u8>>.

Mark debug sections referenced by kept debug sections
If a debug section is referenced by a kept debug section, it should
also be kept.
Some targets, like mips, keep input files when there are some special
sections, like .gnu.attributes, even if input file is unused otherwise.
In this case, all debug sections are kept. The new test will fail on
such targets. We can either fix those targets or XFAIL the test.

Add alias command to cmd_list_element
When we add alias command, we call add_alias_cmd and pass the alias name
and command name. This implicitly requires the command and its prefix
commands are already added to cmdlist. This may not be true, for example,
add_com_alias ("tty", "set inferior-tty", class_alias, 0);
"inferior-tty" command is added to setlist, but setlist may not be added
to cmdlist (It depends on the order of related _initialize_XXX functions
called) so that we can't find "set inferior-tty" from cmdlist.
This patch fixes this problem by passing cmd_list_element of "inferior-tty"
to add_alias_cmd, so that cmd_list_element of "inferior-tty" doesn't have
to be reachable from cmdlist at that moment.

non_ir_ref_dynamic
dynamic_ref_after_ir_def is a little odd compared to other symbol
flags in that as the name suggests, it is set only for certain
references after a definition. It turns out that setting a flag for
any non-ir reference from a dynamic object can be used to solve the
problem for which this flag was invented, which I think is a cleaner.
This patch does that, and sets non_ir_ref only for regular object
references.

* bfdlink.h (struct bfd_link_hash_entry): Update non_ir_ref
comment. Rename dynamic_ref_after_ir_def to non_ir_ref_dynamic.

MIPS16e2: Add MIPS16e2 ASE support
Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:
1. A new ELF ASE flag to mark MIPS16e2 binaries.
2. MIPS16e2 instruction assembly support, including a relaxation update
to use LUI rather than an LI/SLL instruction pair for loading the
high part of 32-bit addresses.
3. MIPS16e2 instruction disassembly support, including updated rules for
extended forms of instructions that are now subdecoded and therefore
do not alias to the original MIPS16 ISA revision instructions even
for encodings that are not valid in the MIPS16e2 instruction set.
Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops. Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.
Parts of this change by Matthew Fortune and Andrew Bennett.

MIPS16/GAS: Improve [32768,65535] out-of-range operand error diagnostics
Improve out-of-range operand error diagnostics for invalid values in the
[32768,65535] range used for a signed 16-bit immediate, making the
message consistent with that used for other invalid values, e.g.:
foo.s:1: Error: operand 2 must be an immediate expression `addiu $2,$gp,32768'
foo.s:2: Error: invalid operands `lw $2,32768($gp)'
vs:
foo.s:3: Error: operand 3 out of range `addiu $2,$gp,-32769'
foo.s:4: Error: operand 2 out of range `lw $2,-32769($gp)'
This case does not currently trigger however, for two reasons.
First, for regular MIPS and microMIPS assembly in the case of no match
caused by `match_int_operand' here, the function is always called again
from `mips_ip' via `match_insns', `match_insn' and then `match_operand'
for the same opcode table's entry with `lax_match' set to TRUE, in which
case the attempt to match succeeds and no error is issued.
Second, in the case of MIPS16 assembly no call to `match_int_operand' is
made at all for signed 16-bit immediates, because such immediates are
currently only matched with extensible instructions, and these are
handled in `match_mips16_insn' via `match_expression' directly rather
than via `match_operand'.
This will change for MIPS16 code with MIPS16e2 support introduced, where
non-extensible instructions accepting signed 16-bit immediates will be
added, so make the case work well right from the start:
foo.s:1: Error: operand 3 out of range `addiu $2,$gp,32768'
foo.s:2: Error: operand 2 out of range `lw $2,32768($gp)'

* config/tc-mips.c (match_int_operand): Call
`match_out_of_range' before returning failure for 0x8000-0xffff

MIPS16/GAS: Improve non-constant operand error diagnostics
Improve operand error diagnostics for non-constant expressions used for
a 16-bit immediate, making the message more descriptive and indicating
the offending operand, e.g.:
foo.s:1: Error: invalid operands `lui $2,foo-bar'
will show as:
foo.s:1: Error: operand 2 must be constant `lui $2,foo-bar'
This case does not currently trigger however, for two reasons.
First, for regular MIPS and microMIPS assembly in the case of no match
caused by `match_int_operand' here, the function is always called again
from `mips_ip' via `match_insns', `match_insn' and then `match_operand'

MIPS/GAS: Improve bignum operand error diagnostics
Improve bignum operand error diagnostics for cases where a constant
would be accepted and report them as range errors, also indicating the
offending operand and instruction, e.g.:
$ cat bignum.s
addiu $2, 0x10000000000000000
break 0x10000000000000000
$ as -o bignum.o bignum.s
bignum.s:1: Error: bignum invalid
bignum.s:2: Error: operand 1 must be constant `break 0x10000000000000000'
$
now show as:
$ as -o bignum.o bignum.s
bignum.s:1: Error: operand 2 out of range `addiu $2,0x10000000000000000'

MIPS16/GAS: Improve non-immediate operand error diagnostics
Improve non-immediate operand error diagnostics for extensible MIPS16
instructions and make it match corresponding regular MIPS and microMIPS
handling, e.g:
$ cat addiu.s
addiu $4, $3, $2
$ as -o addiu.o addiu.s
addiu.s: Assembler messages:
addiu.s:1: Error: operand 3 must be an immediate expression `addiu $4,$3,$2'
$ as -mips16 -o addiu.o addiu.s
addiu.s: Assembler messages:
addiu.s:1: Error: invalid operands `addiu $4,$3,$2'
$
To do so observe that for extensible MIPS16 instructions and a non-PC
relative operand this case is handled by an explicit OT_INTEGER check in
`match_mips16_insn' returning a failure right away and consequently
preventing a call to `match_expression' from being made. As from commit
d436c1c2e889 ("Improve error reporting for register expressions"),
<https://sourceware.org/ml/binutils/2013-08/msg00134.html>, however the
check has become redundant as `match_expression' now only ever returns
success for OT_INTEGER argument tokens, and a special case of an OT_CHAR
`(' token already handled by `match_mips16_insn' just ahead of the
`match_expression' call. Previously it also returned success for OT_REG
argument tokens.
Let the call to `match_expression' always happen then, yielding the same
failure for the affected cases, however with more accurate diagnostics
provided by the call making reporting consistent:
$ as -mips16 -o addiu.o addiu.s
addiu.s: Assembler messages:
addiu.s:1: Error: operand 3 must be an immediate expression `addiu $4,$3,$2'
$
gas/

OT_INTEGER check before the `match_expression' call.

MIPS16/GAS: Improve disallowed relocation operand error diagnostics
Improve disallowed relocation operand error diagnostics for MIPS16 code
and make it match corresponding regular MIPS and microMIPS handling,
e.g:
$ cat sltu.s
sltu $2, %lo(foo)
$ as -o sltu.o sltu.s
sltu.s: Assembler messages:
sltu.s:1: Error: operand 2 must be constant `sltu $2,%lo(foo)'
$ as -mips16 -o sltu.o sltu.s
sltu.s: Assembler messages:
sltu.s:1: Error: invalid operands `sltu $2,%lo(foo)'
$
To do so call `match_not_constant' from `match_mips16_insn' whenever a
disallowed relocation operation has been noticed, like `match_const_int'
does, making reporting consistent:
$ as -mips16 -o sltu.o sltu.s
sltu.s: Assembler messages:
sltu.s:1: Error: operand 2 must be constant `sltu $2,%lo(foo)'

Complement commit 919731affbef ("Add MIPS .module directive") and update

`.set' and like the respective command-line option the use of the

corresponds to the respective command-line option.

Avoid exponential behavior in rust_evaluate_subexp
The STRUCTOP_STRUCT case in rust_evaluate_subexp would evaluate its
LHS, and then, if it did not need Rust-specific treatment, it would
back up and re-evaluate the entire STRUCTOP_STRUCT part of the
expression using evaluate_subexp_standard. This yields exponential
behavior and causes some expressions to evaluate extremely slowly.
The fix is to simply do the needed work inline.
This is PR rust/21483.

Fix rust_dump_subexp_body
rust_dump_subexp_body was not correct in a couple of cases. While
debugging the bug I was really interested in, this caused a crash.
This patch fixes the problems. No test case because, IIRC there
generally aren't tests for expression dumping.

MIPS/GAS: Unify GP-relative percent-ops
For a reason that is unclear commit d6f165938798 ("Support for MIPS16
HI16/LO16 relocations"),
<https://sourceware.org/ml/binutils/2005-02/msg00332.html>, which has
added support for the R_MIPS16_GPREL relocation, has spelled its
corresponding MIPS16 percent-op as `%gprel', rather than `%gp_rel' which
is how its regular MIPS counterpart is spelled. To make assembly code
sharing easier between the regular MIPS and the MIPS16 ISA make both
percent-op spellings acceptable in both kinds of code now.
Parts of this change by Matthew Fortune.

bfd: fix the deletion of relocs in sparc64
This patch fixes the deletion of relocations in BFD sections in
sparc64 targets.
A specialized `_bfd_set_reloc' function is provided that updates the
internal canon_reloc_count(sec) counter instead of sec->reloc_count.
Additionally, the `write_relocs' callback in elf64-sparc is adapted to
use the canon_reloc_count to traverse `sec->orelocation'.
Tested in sparc64-linux-gnu targets.
Fixes an existing failure in the merge-notes objcopy test.
No regressions.

x86-64: Improve PLT generation and synthetic PLT symbols
On x86-64, the procedure linkage table (PLT) is used to
1. Call external function.
2. Call internal IFUNC function. The best implementation is selected
for the target processor at run-time.
3. Act as the canonical function address.
4. Support LD_AUDIT to audit external function calls.
5. Support LD_PROFILE to profile external function calls.
PLT looks like:
PLT0: push GOT[1]
jmp *GOT[2]
nop
PLT1: jmp *GOT[name1_index]
push name1_reloc_index
jmp PLT0
GOT is an array of addresses. Initially the GOT entry of name1 is
filled with the address of the "push name1_reloc_index" instruction.
The function, name1, is called via "jmp *GOT[name1]" in the PLT entry.
Even when lazy binding is disabled by "-z now", the PLT0 entry may
still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for
canonical function address.
When linker is invoked with "-z bndplt", a different PLT layout in .plt
is used:
PLT0: push GOT[1]
bnd jmp *GOT[2]
nop
PLT1: push name1_reloc_index
bnd jmp PLT0
nop
together with a second PLT section, .pl.bnd:
PLT1: bnd jmp *GOT[name1_index]
nop
where the GOT entry of name1 is filled with the address of the push
instruction of the corresponding entry in .plt.
1. With lazy binding, when the external function, name1, is called the
first time, dynamic linker is called via PLT0 to update GOT[name1_index]
with the actual address of name1 and transfers control to name1
afterwards.
2. PLT is also used to call a local IFUNC function, name1, run-time
loader updates GOT[name1_index] when loading the module.
This patch
1. Remove PLT layout configurations from x86-64 backend_data.
2. Add generic, lay and non-lazy PLT layout configurations to x86-64
link_hash_table. Generic PLT layout includes the PLT entry templates,
information how to update the first instruction in PLT and PLT eh_frame
informaton, which are initialized in x86-64 setup_gnu_properties, based
on "-z bndplt" and target selection. PLT section alignment is also set
to PLT entry size for non-NaCl target.
3. Remove elf_x86_64_create_dynamic_sections. create_dynamic_sections
isn't always called, but GOT relocations need GOT relocations. Instead,
create all x86-64 specific dynamic sections with alignment to their entry
size in x86-64 setup_gnu_properties, which initializes elf.dynobj, so
that x86-64 check_relocs can be simplified.
4. Rewrite elf_x86_64_get_synthetic_symtab to check PLT sections against
all dynamic relocations to support both lazy and non-lazy PLTs.
There is no change in PLT. The only externally visible change is the
improvement of synthetic PLT symbols for .plt.got.

i386: Improve PLT generation and synthetic PLT symbols
On i386, the procedure linkage table (PLT) is used to
1. Call external function.
2. Call internal IFUNC function. The best implementation is selected
for the target processor at run-time.
3. Act as the canonical function address.
4. Support LD_AUDIT to audit external function calls.
5. Support LD_PROFILE to profile external function calls.
PLT looks like:
PLT0: push GOT[1]
jmp *GOT[2]
nop
PLT1: jmp *GOT[name1_index]
push name1_reloc_index
jmp PLT0
GOT is an array of addresses. Initially the GOT entry of name1 is
filled with the address of the "push name1_reloc_index" instruction.
The function, name1, is called via "jmp *GOT[name1]" in the PLT entry.
Even when lazy binding is disabled by "-z now", the PLT0 entry may
still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for
canonical function address.
1. With lazy binding, when the external function, name1, is called the
first time, dynamic linker is called via PLT0 to update GOT[name1_index]
with the actual address of name1 and transfers control to name1
afterwards.
2. PLT is also used to call a local IFUNC function, name1, run-time
loader updates GOT[name1_index] when loading the module.
This patch
1. Remove PLT layout configurations from i386 backend_data.
2. Add generic, lay and non-lazy PLT layout configurations to i386
link_hash_table. Generic PLT layout includes the PLT entry templates,
information how to update the first instruction in PLT and PLT eh_frame
informaton, which are initialized in i386 setup_gnu_properties, based
on PIC and target selection. PLT section alignment is also set to PLT
entry size for non-NaCl/VxWorks target.
3. Remove elf_i386_create_dynamic_sections. create_dynamic_sections
isn't always called, but GOT relocations need GOT relocations. Instead,
create all i386 specific dynamic sections in i386 setup_gnu_properties,
which initializes elf.dynobj, so that i386 check_relocs can be simplified.
4. Rewrite elf_i386_get_synthetic_symtab to check PLT sections against
all dynamic relocations to support both lazy and non-lazy PLTs.

Make import libraries relocatable objects
For ELF targets --out-implib currently generates an executable file
(e_type is ET_EXEC) despite the file being expected to be linked against
some other object file to make an executable later. It seems therefore
more sensible to make the import library a relocatable object file
(e_type set to ET_REL).
Incidentally, as dicted by requirement 8 of
"ARM v8-M Security Extensions: Requirements on Development Tools"
(document ARM-ECM-0359818) version 1.0, import libraries generated when
using --cmse-implib *must* be relocatable object file so this commit
also adds an assert there in case the type of ELF import library is
changed again in the future.

Rearrange gdb/configure.nat to make it simpler and less redundant
The previous commit introduced gdb/configure.nat, but it was just a
copy-and-past (with the necessary adjustments) from the files under
gdb/config/. We can do better than that.
Instead of using one big 'case' statement that matches the
${gdb_host_cpu} and then match each ${gdb_host}, it is possible to
remove a lof of redundancy by matching the most common ${gdb_host}'s
first, setting the common variables for each, and then proceed to
matching specific ${gdb_host}'s and ${gdb_host_cpu}'s. In other
words, reverse the order of the 'case's and take advantage of the fact
that a lot of parameters are the same for each host.
This commit was tested on x86_64 without regressions.

* configure.nat: Rearrange 'case' statements to match
host before cpu.
commit 21ea5acdd1bcfe89984b16b5bac730050c5cf05e

Introduce "gdb/configure.nat" (and delete "gdb/config/*/*.mh" files)
Due to my ongoing work to make it possible for gdbserver to start the
inferior using the shell, I had to share the fork_inferior function
under the "nat/" directory. In order to do that, I created a new file
and put the function there; however, this meant that I now had to
update some of the *.mh files (under "gdb/config") and add the new
file as a dependency to be built natively. Bleh...
After talking a bit to Pedro about this, the idea came up to write a
new "gdb/configure.nat" file, a la "gdb/configure.tgt", which would
concentrate all of the native settings for each host/system. I
decided to tackle this issue.
The patch is simple. All of the previous Makefile variables that were
being declared inside the *.mh files are now inside "gdb/Makefile.in",
and "gdb/configure" is responsible for AC_SUBST'ing them. The
definitions of these variables were put inside "gdb/configure.nat", so
now they're shell variables. For excerpts of Makefile code, one must
create a file under "gdb/config/${gdb_cpu_host}" and reference it on
the "nat_extra_makefile_frag" variable.
It should now be easier to update the native dependencies of hosts in
this single file.
This has been tested on x86_64 without regressions.
gdb/ChangeLog:
2017-05-06 Sergio Durigan Junior <sergiodj@redhat.com>
* Makefile.in: Remove "@host_makefile_frag@". Add variables
NAT_FILE, NATDEPFILES, NAT_CDEPS, LOADLIBES, MH_CFLAGS, XM_CLIBS,
NAT_GENERATED_FILES, HAVE_NATIVE_GCORE_HOST. Add

gdb: Disable -Werror for -Wmaybe-uninitialized
Newer GCCs are triggering false-positive -Wmaybe-uninitialized
warnings around code that uses gdb::optional:
https://sourceware.org/ml/gdb-patches/2017-05/msg00118.html
Using std::optional wouldn't help, it triggers the same warnings:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80635
Initializing the variables to quiet the warning would defeat the
purpose of gdb::optional. Making the optional ctor memset its storage
would be a pessimization. Wrapping gdb::optional's internals with
"#pragma GCC diagnostic push/ignored/pop" doesn't work, we'd have to
wrap uses of gdb::optional instead, which I think would get unwieldy
and ugly as we start using gdb::optional more and more.
The -Wmaybe-uninitialized warning is documented as producing false
positives (unlike -Wuninialized), so until we find a better
workaround, disable -Werror for this warning. You'll still see the
warning when building gdb, but it won't cause a build failure.
Tested by building with gcc 4.8.5, 5.3.1, and gcc trunk (20170428).

Fix get_core_register_section leak, introduce thread_section_name
This plugs a leak introduced in the previous change to
get_core_register_section, which removed an xfree call that is
actually necessary because the 'section_name' local is static.
From [1] it looks like the reason the variable was made static to
begin with, was just "laziness" to avoid having to think about freeing
it on every function return path:
https://sourceware.org/ml/gdb-patches/2005-03/msg00237.html
The easiest to fix that nowadays is to use a std::string.
I don't see a need to xstrdup the section name in the single-threaded
case though, and also there's more than one place that computes a
multi-threaded section name in the same way. So put the section name
computation in a wrapper class with state.

Fix PR21404 - assertion fail when calculating symbol size
Fix a host of problems related to adjustment of
symbol values and sizes when relaxing for avr.
1. Adjust symbol size first before adjusting symbol
value. Otherwise, a symbol whose value just got adjusted to the
relaxed address also ends up getting resized. See pr21404-1.s.
2. Reduce symbol sizes only if their span is below an
alignment boundary. Otherwise, the size gets decremented once when the
actual instruction is relaxed and padding bytes are added, and again
when the padding bytes are deleted (if padding ends up being unnecessary).
pr21404-2.s addresses that, and this bug is really the root cause of PR21404.
3. Adjust all symbol values before an alignment boundary.
Previous code did not adjust symbol values if they fell in the
would-be padded area, resulting in incorrect symbol values in some
cases (see pr21404-3.s).
4. Increase symbol sizes if alignment directives require so.
As pr21404-4.s shows
.global nonzero_sym
L1:
jmp L1
nonzero_sym:
nop
nop
.p2align 2
.size nonzero_sym, .-nonzero_sym
The two nops satisfy the 4 byte alignment at assembly time and
therefore the size of nonzero_sym is 4. Relaxation shortens
the 4 byte jmp to a 2 byte rjmp, and to satisfy 4 byte alignment
the code places 2 extra padding bytes after the nops, increasing
nonzero_sym's size by 2. This wasn't handled before.
If the assembly code does not have any align directives, then the
boundary is the section size, and symbol values and sizes == boundary
should also get adjusted. To handle that case, add a did_pad variable
and use that to determine whether it should use < boundary or <= boundary.
Also get rid of reloc_toaddr, which is now redundant. toaddr is now not
adjusted to handle the above case - the newly added
did_pad variable does the job.
pr21404-{5,6,7,8} are the same testcases written for local symbols, as
the code handles them slightly differently.

MIPS16/GAS: Relax 32-bit non-PIC PC-relative synthetic instructions
Implement the relaxation of MIPS16 PC-relative synthetic LA, DLA, LW and
LD instructions to an equivalent sequence of instructions produced where
the address operand requested is out of range, absolute or requires
linker relocation, for ABIs that use 32-bit addressing and non-PIC code.
The sequence generated uses the register specified for the destination
operand as a temporary and begins with LI to load the high 16-bit part
of the address, then continues with SLL by 16 bits to move that part
into place and finally completes with a suitable operation corresponding
to the synthetic instruction used, one of: 2-argument ADDIU, 2-argument
DADDIU, absolute LW, and absolute LD respectively, providing the low
16-bit part of the address. All instructions use the extended encoding.
As a special exception accept absolute addresses for relaxation even in
PIC code.
For example:
la $2, 0x12345678
produces code as:
li $2, 0x1234
sll $2, $2, 16
addiu $2, 0x5678
would.
Where linker relocation is required emit an R_MIPS16_HI16 relocation on
the initial LI instruction and an R_MIPS16_LO16 relocation on the final
operation.
For example (where `foo' is not local):
lw $3, foo
produces code as:
li $3, %hi(foo)
sll $3, $3, 16
lw $3, %lo(foo)($3)
would.
Emit assembly warnings as appropriate where this new relaxation triggers
in the `nomacro' mode or for an instruction manually placed in a branch
delay slot in the `noreorder' mode. Refrain from relaxation where an
explicit instruction size suffix has been used and in the `noautoextend'
mode.

MIPS16/GAS: Fix absolute references with PC-relative synthetic instructions
Complement commit 88a7ef168927 ("MIPS16/GAS: Restore unsupported
relocation diagnostics") and also propagate constant expressions, either
already reduced from absolute symbol references or created from literals
in the first place, used as a PC-relative operand with the MIPS16 LA,
LW, DLA and LD synthetic instructions to relaxation, matching the way
forward absolute symbol references have been handled as from the commit
referred and letting relaxation produce any necessary relocations, if
possible, for the absolute value requested to be reproduced at the run
time.
Call `symbol_append' for any expression symbol created for the purpose
of MIPS16 relaxation as with constant expressions now propagated from
earlier on such symbols may make it through and have R_MIPS16_PC16_S1
relocations emitted against, and therefore need to appear in the symbol
table produced.

RISC-V: Change CALL macro to use ra as the temporary address register
e.g.
1: auipc ra, %pcrel_hi(symbol)
jalr ra, %pcrel_lo(1b)(ra)
The use of ra instead of t1 for address construction provides an
opportunity for a microarchitecture to elide the write of the
destination address, and instead read the target address as an
immediate spread across the fused auipc+jalr pair. The link
register ra in the jalr overwrites the target address temporary.
2017-05-01 Michael Clark <michaeljclark@mac.com>
* riscv-opc.c (riscv_opcodes) <call>: Use RA not T1 as a temporary
register.

RISC-V: Allow 32-bit BFD to handle 64-bit objects
We've been telling people that the riscv32-* and riscv64-* toolchains
are exactly the same, but it turns out we were lying: the riscv32-* BFD
doesn't handle 64-bit objects. This fixes that difference, so the ports
are actually the same.

Change field separator in gdbarch.sh
The fields in the description of the gdbarch interface are separated
using colons. That becomes a problem if we want to use things like
std::vector in it. This patch changes the field separator to use
semicolons instead.
I think there's very little chance we'll ever want to use a semicolon in
one of the fields, but if you think another character would be more
appropriate, let me know.
gdb/ChangeLog:
* gdbarch.sh: Use semi-colon as field separator instead of colon.

Make environ.exp run on all platforms (and create info-program.exp)
This has been on my TODO list for a while. There's a really old bug
about this (PR testsuite/8595), and there was no reason for
environ.exp to be specific for hppa* targets. So this patch removes
this constraint, modernizes the testcase, and cleans up some things.
Most of the tests remained, and some were rewritten (especially the
one that checks if "show environment" works, which is something kind
of hard to do).
As a bonus, I'm adding a separated info-program.exp file containing
all the tests related to "info program" that were present on
environ.exp.
Tested locally, everything still passes.

Make various lm_info implementations inherit from a base class
The lm_info structure is used to store target specific information about
mapped libraries. It is currently defined as an opaque type in solist.h
and a pointer to it is included in solist, the target-agnostic object
representing a loaded shared library. Multiple targets define their own
implementation of lm_info.
In anticipation of using C++ stuff (e.g. vector) in the lm_info objects,
we first need to avoid different definitions of classes with the same
name (which violates the one definition rule). This patch does it by
having a base class (lm_info_base) from which all the specific lm_info
derive. Each implementation is renamed to something that makes sense
(e.g. lm_info_aix for AIX). The next logical step would probably be to
derive directly from so_list, it's not really obvious, so I'll keep that
for another day.
One special case is the Neutrino (nto) support. It uses SVR4-style
libraries, but overrides some methods. To do that, it needed to have
its own copy of SVR4's lm_info structure in nto-tdep.c, because it was
just not possible to put it in solib-svr4.h and include that file. Over
time, that copy got out of sync, which is still the case today. I can
only assume that the lm_addr function in nto-tdep.c is broken right now.
The first field of the old lm_info was a pointer (gdb_byte *), whereas
in the new lm_info it's an address in the inferior (CORE_ADDR). Trying
to use that field today probably results in a crash. With this
refactor, it's now possible to put lm_info_svr4 in solib-svr4.h and just
include it. I have adapted the code in nto-tdep.c to that it builds,
but it's probably not correct. Since I don't have the knowledge nor
setup to try this on Neutrino, somebody else would have to fix it. But
I am confident that I am not making things worse than they already are.

Standardize darwin's lm_info
Darwin's lm_info structure is used a little bit differently than the
other solib implementations. The other implementations first allocate
an so_list object, then instanciate their specific lm_info structure,
and assign it to so_list::lm_info.
The Darwin implementation allocates both at the same time
(darwin_so_list). This patch changes it to be like the others, so that
we'll be able to do some generalizations later.
gdb/ChangeLog:
* solib-darwin.c (struct darwin_so_list): Remove.
(darwin_current_sos): Allocate an so_list object instead of a
darwin_so_list, separately allocate an lm_info object.

Fix overload resolution involving rvalue references and cv qualifiers.
The following patch fixes several outstanding overload resolution problems
with rvalue references and cv qualifiers in the test suite. The tests for
these problems typically passed with one compiler version and failed with
another. This behavior occurs because of the ordering of the overloaded
functions in the debug info. So the first best match "won out" over the
a subsequent better match.
One of the bugs addressed by this patch is the failure of rank_one_type to
account for type equality of two overloads based on CV qualifiers. This was
leading directly to problems evaluating rvalue reference overload quality,
but it is also highlighted in gdb.cp/oranking.exp, where two test KFAIL as
a result of this shortcoming.
I found the overload resolution code committed with the rvalue reference
patch (f9aeb8d49) needlessly over-complicated, and I have greatly simplified
it. This fixes some KFAILing tests in gdb.exp/rvalue-ref-overload.exp.

Add missing incref when creating Inferior Python object
The test py-inferior.exp fails when using a debug build of Python 3.6. I don't
see it failing with my system's default Python, but it might be related to the
different memory allocation scheme used when doing a build with pydebug.
The issue is that we are missing a Py_INCREF in
inferior_to_inferior_object. The PyObject_New function initializes the
object with a refcount of 1. If we assume that this refcount
corresponds to the reference we are returning, then we are missing an
incref for the reference in the inferior data.
The counterpart for the incref that corresponds to the reference in the
inferior data is in py_free_inferior, in the form the gdbpy_ref instance.
Here's how I can get it to crash (with some debug output):
$ ./gdb -nx -ex "set debug python 1"
(gdb) add-inferior
Added inferior 2
(gdb) python infs = gdb.inferiors()
Creating Python Inferior object inf = 1
Creating Python Inferior object inf = 2
(gdb) remove-inferiors 2
py_free_inferior inf = 2
infpy_dealloc inf = <unknown>
(gdb) python infs = None
Fatal Python error: Objects/tupleobject.c:243 object at 0x7f9cf1a568d8 has negative ref count -1
Current thread 0x00007f9cf1b68780 (most recent call first):
File "<string>", line 1 in <module>
[1] 408 abort (core dumped) ./gdb -nx -ex "set debug python 1"
After having created the inferiors object, their refcount is 1 (which
comes from PyObject_New), but it should be two. The gdb inferior object
has a reference and the "infs" list has a reference.
When invoking remove-inferiors, py_free_inferior gets called. It does
the decref that corresponds to the reference that the gdb inferior
object kept. At this moment, the refcount drops to 0 and the object
gets deallocated, even though the "infs" list still has a reference.
When we set "infs" to None, Python tries to decref the already zero
refcount and the assert triggers.
With this patch, it looks better:
(gdb) add-inferior
Added inferior 2
(gdb) python infs = gdb.inferiors()
Creating Python Inferior object inf = 1
Creating Python Inferior object inf = 2
(gdb) remove-inferiors 2
py_free_inferior inf = 2
(gdb) python infs = None
infpy_dealloc inf = <unknown>

MIPS/GAS: Fix `.option picX' handling with relaxation
Correct the handling of `.option pic0' and `.option pic2' GAS pseudo-ops
in relaxation and use the setting of `mips_pic' (which these directives
control) as at the time a relaxed frag has been created rather than the
final `mips_pic' setting at the end of the source file processed.
To do so record whether `mips_pic' is NO_PIC or not in the frag itself
and use this information throughout relaxation instead of `mips_pic' to
decide which of NO_PIC or SVR4_PIC to produce machine code for, fixing
code generation and removing a possible fatal failure reproducible with:
$ as -32 --relax-branch -o option-pic-relax-3.o option-pic-relax-3.s
option-pic-relax-3.s: Assembler messages:
option-pic-relax-3.s:7: Warning: relaxed out-of-range branch into a jump
option-pic-relax-3.s: Internal error in cvt_frag_to_fill at .../gas/write.c:490.
Please report this bug.
$
using the test source included, due to a buffer overrun in filling the
variable part of a frag.
Likewise use the `fx_tcbit2' flag of a BFD_RELOC_16_PCREL_S2 fixup to
handle the simple case of substituting an out of range unconditional
branch with an equivalent absolute jump in NO_PIC code.
Retain the current way of VXWORKS_PIC use, which commit 41a1578ed17c

[gdbarch] New method "execute_dwarf_cfa_vendor_op" and migrate SPARC to it
Recently a feature called "return address signing" has been added to GCC to
prevent stack smash stack on AArch64. For details please refer:
https://gcc.gnu.org/ml/gcc-patches/2017-01/msg00376.html
GDB needs to be aware of this feature so it can restore the original return
address which is critical for unwinding.
On compiler side, whenever return address, i.e. LR register, is mangled or
restored by hardware instruction, compiler is expected to generate a
DW_CFA_AARCH64_negate_ra_state to toggle return address signing status.
DW_CFA_AARCH64_negate_ra_state is using the same CFI number and
therefore need to be multiplexed with DW_CFA_GNU_window_save which was designed
for SPARC.
A new gdbarch method "execute_dwarf_cfa_vendor_op" is introduced by this patch.
It's parameters has been restricted to those only needed by SPARC and AArch64
for multiplexing DW_CFA_GNU_window_save which is a CFI operation takes none
operand. Should any further DWARF CFI operation want to be multiplexed in the
future, the parameter list can be extended. Below is the current function
prototype.
typedef int (gdbarch_execute_dwarf_cfa_vendor_op_ftype)
(struct gdbarch *gdbarch, gdb_byte op, struct dwarf2_frame_state *fs);
DW_CFA_GNU_window_save support for SPARC is migrated to this new gdbarch
method by this patch.

MIPS/readelf: With `-A' also dump GOT in static binaries
A static, non-relocated global offset table will be embedded in static
binaries produced from objects containing any kind of GOT relocations,
generally PIC code. All symbols will have been resolved in static link
in such binaries making all GOT entries local and their values final as
there is no run-time load processing further performed.
Dump such GOT with `readelf -A' like already done with regular GOT, to
make it easier to examine static code that uses accesses via the GOT
pointer. There will be no dynamic segment or section in a static binary
to get the GOT pointer (DT_PLTGOT) from, so use section headers to find
a `.got' section instead.

MIPS/readelf: Simplify GOT[1] data availability check
Unavailable data is handled gracefully in MIPS GOT processing done by
`print_mips_got_entry', so all that is needed in special GOT[1] handling
is to verify whether data can be retrieved for the purpose of the GNU
marker check done with `byte_get'. Remove the extra error reporting
code then, introduced with commit 75ec1fdbb797 ("Fix runtime seg-fault

Don't memset non-POD types: struct btrace_insn
struct btrace_insn is not a POD [1] so we shouldn't be using memset to

Use list-initialization instead, wrapped in a "pt insn to btrace insn"
function, which looks like just begging to be added next to the
existing pt_reclassify_insn/pt_btrace_insn_flags functions.

So, VECs (given it's C roots) rely on memcpy/memcpy of VEC elements to
be well defined, in order to grow/reallocate its internal elements
array. This means that we can only put trivially copyable types in
VECs. E.g., if a type requires using a custom copy/move ctor to
relocate, then we can't put it in a VEC (so we use std::vector
instead). But, as shown above, we're violating that requirement.
btrace_insn is currently not trivially copyable, because it contains
an enum_flags field, and that is itself not trivially copyable. This
patch corrects that, by simply removing the user-provided copy
constructor and assignment operator. The compiler-generated versions
work just fine.
Note that std::vector relies on std::is_trivially_copyable too to know
whether it can reallocate its elements with memcpy/memmove instead of
having to call copy/move ctors and dtors, so if we have types in
std::vectors that weren't trivially copyable because of enum_flags,
this will make such vectors more efficient.

[GAS/ARM] Fix expansion of ldr pseudo instruction
The LDR rX, =cst pseudo-instruction suffers from two issues for loading
integer constants in Thumb mode:
- movs is used if the constant and register can be encoded using that
instruction which leads to unexpected behavior due to its flag-setting

doc: Improve documentation about MI thread output
I noticed that the documentation on how the info about threads is output
in MI is duplicated and not up to date. The duplication is between the
"GDB/MI Thread Information" page and the -thread-info result
description.
I improved the "GDB/MI Thread Information" page a bit and referred to it
in the -thread-info doc. This way, the -thread-info doc is more precise
(it did not mention the "threads" and "current-thread-id" attributes)
and concise.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Information): Add missing
fields, re-word some things.
(GDB/MI Thread Commands): Describe fields found in the output of
-thread-info, remove description of fields in the
thread output tuple, replace with a cross-reference to "GDB/MI
Thread Information".

Remove dead code and "current" field from MI thread output doc
The MI documentation says that -thread-info output contains a "current"
field in the current thread tuple, with the value "*". Current GDB
master does not do this, and I couldn't find any GDB version that did.
I suspect that it was never the case.
The code that would correspond to this in print_thread_info_1 is
essentially dead code. The calls to uiout->text end up in
mi_out::do_text, which is empty.
This patch removes the documentation bit and the dead code. This
"current" field is not necessary, since -thread-info outputs a
"current-thread-id" field.
gdb/ChangeLog:
* thread.c (print_thread_info_1): Remove dead code.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Commands): Remove "current" field
from -thread-info output.

Simplify regcache_restore
This patches removes the 2nd argument of regcache_restore, because it
is only called by regcache_cpy. In regcache_cpy, if regcache_restore
is called, dst is not readonly, but src is readonly. So this patch
adds an assert that src is readonly in regcache_restore.
regcache_cook_read read everything from a readonly regcache cache
(src)'s register_buffer, and register status is from ->register_status.

Skip PIE indirect5 and indirect6 tests on i386
On i386, since GOT reference is needed to access global symbols in PIE,
those symbols are made dynamic. Crash happens when there is a reference
to the same global symbol with a different symbol type in a shared
object. Since mixing different types of the same symbol doesn't work in
general, this patch skips those tests on i386 as well as compiles non-PIE
indirect5 and indirect6 tests with $NOPIE_LDFLAGS and $NOPIE_CFLAGS.

$NOPIE_CFLAGS to non-PIE indirect5 and indirect6 tests. Skip

ELF/LD: Always consider STB_LOCAL symbols local
Do not require forced local (STB_LOCAL) symbols to have a definition in
a regular file to be considered to resolve local to the current module,
matching `elf_link_renumber_local_hash_table_dynsyms'. In the absence
of a regular definition any reference to a STB_LOCAL symbol will have to
be garbage collected along with the undefined symbol itself, or the link
will eventually fail. Either way the symbol concerned is not going to
be external.

Handle symbol defined in IR and referenced in DSO
We need to make an IR symbol visible if it is defined in an IR object
and referenced in a dynamic object. When --as-needed is used, since
linker removes the IR symbol reference of the dynamic object if the
dynamic object isn't needed in the first pass, the IR definition isn't
visible to the dynamic object even if the dynamic object becomes needed
in the second pass. Add dynamic_ref_after_ir_def to bfd_link_hash_entry
to track IR symbol which is defined in an IR object and later referenced
in a dynamic object. dynamic_ref_after_ir_def is preserved when restoring
the symbol table for unneeded dynamic object.

Fix removing inferiors from within "thread apply" commands
This patch fixes an internal error exposed by a test that does
something like:
define kill-and-remove
kill inferiors 2
remove-inferiors 2
end
# Start one inferior.
start
# Start another inferior.
add-inferior 2
inferior 2
start
# Kill and remove inferior 1 while inferior 2 is selected.
thread apply 1.1 kill-and-remove
The internal error looks like this:
Thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677)):
[Switching to inferior 1 [process 20677] (gdb/testsuite/outputs/gdb.threads/threadapply/threadapply)]
[Switching to thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677))]
#0 main () at src/gdb/testsuite/gdb.threads/threadapply.c:38
38 for (i = 0; i < NUM; i++)
src/gdb/inferior.c:66: internal-error: void set_current_inferior(inferior*): Assertion `inf != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/threadapply.exp: kill_and_remove_inferior: try kill-and-remove: thread apply 1.1 kill-and-remove (GDB internal error)
There are several problems around this area of the code. One is that
in do_restore_current_thread_cleanup, we do a look up of inferior by
ptid, which can find the wrong inferior if the previously selected
inferior exited and some other inferior was started with a reused pid
(rare, but still...).
The other problem is that the "remove-inferiors" command rejects
attempts to remove the current inferior, but when we get to
"remove-inferiors" in a "thread apply THR remove-inferiors 2" command,
the current inferior is the inferior of thread THR, not the previously
selected inferior, so if the previously selected inferior was inferior
2, that command still manages to wipe it, and then gdb restores the
old selected inferior, which is now a dangling pointer...
So the fix here is:
- Make make_cleanup_restore_current_thread store a pointer to the
previously selected inferior directly, and use it directly instead
of doing ptid look ups.
- Add a refcount to inferiors, very similar to thread_info's refcount,
that is incremented/decremented by
make_cleanup_restore_current_thread, and checked before deleting an
inferior. To avoid duplication, a new refcounted_object type is
added, that both thread_info and inferior inherit from.

Make inferior::detaching a bool, and introduce scoped_restore::release()
I left making inferior::detaching a bool to a separate patch, because
doing that makes a make_cleanup_restore_integer call in
infrun.c:prepare_for_detach no longer compile (passing a 'bool *' when
an 'int *' is expected). Since we want to get rid of cleanups anyway,
I looked at converting that to a scoped_restore. However,
prepare_for_detach wants to discard the cleanup on success, and
scoped_restore doesn't have an equivalent for that. So I added one --
I called it "release()" because it seems like a natural fit in the way
standard components call similarly-spirited methods, and, it's also
what the proposal for a generic scope guard calls it too, AFAICS:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4189.pdf
I've added some scoped_guard unit tests, while at it.

gdb_xml_parser: make data fields private and make more functions methods
This patch makes the data fields of gdb_xml_parser private, and makes
more functions be gdb_xml_parser methods. This is mostly for better
encapsulation.
Some free functions have their parsing-related guts converted to
methods, while the free functions remain, as they're used as expat
callbacks. Now their only job is to be small shims that restore back
the gdb_xml_parser type, defer work to the corresponding method, and
make sure C++ exceptions don't cross expat.
More C++-fycation of the XML parsers built on top of gdb_xml_parser
could follow, but this was my stopping point.

gdb::optional unit tests
I thought I'd add some unit tests to make sure gdb::optional behaved
correctly, and started writing some, but then thought/realized that
libstdc++ already has extensive testing for C++17 std::optional, which
gdb::optional is a subset of, and thought why bother writing something
from scratch. So I tried copying over a subset of libstdc++'s tests
(that ones that cover the subset supported by gdb::optional), and was
positively surprised that they mostly work OOTB. This did help shake
out a few bugs from what I was implementing in the previous patch to
gdb::optional. Still, it's a good chunk of code being copied over, so
if people dislike this copying/duplication, I can drop this patch.

More gdb::optional features
Currently we can't use gdb::optional<T> as function return type,
because gdb::optional's copy ctor is deleted. For example, with:
gdb::optional<int> function ()
{
gdb::optional<int> opt;
....
return opt;
we get:
src/gdb/foo.c: In function â??gdb::optional<int> foo()â??:
src/gdb/foo.c:75:10: error: use of deleted function â??gdb::optional<T>::optional(const gdb::optional<T>&) [with T = int]â??
return opt;
^
In file included from src/gdb/foo.c:68:0:
src/gdb/common/gdb_optional.h:53:3: note: declared here
optional (const optional &other) = delete;
^
I started by fixing that, and then ran into another missing feature,
also fixed by this patch.
The next feature I'm missing most from gdb::optional<T> compared to
std::optional<T> is construction/move/assignment from a T, instead of
having to default construct an gdb::optional and then use
optional::emplace(....).
For example:
gdb::optional<std::string> function ()
{
gdb::optional<std::string> opt;
std::string str;
...
opt.emplace (std::move (str));
return opt;
vs
gdb::optional<std::string> function ()
{
std::string str;
...
return str;
The copy/move ctor/assign methods weren't initialy implemented because
std::optional supports construction from a type U if U is convertible
to T too, and has rules to decide whether the ctors are
explicit/implicit based on that, and rules for whether the ctor should
be trivial or not, etc., which leads to a much more complicated
implementation.
If we stick to supporting copy/move construction/assignment of/to an
optional<T> from exactly only optional<T> and T, then all that
conversion-related complication disappears, and we still gain
convenience in most use cases.
The patch also makes emplace return a reference to the constructor
object, per C++17 std::optional, and adds a reset method, againt
because std::optional has one and it's trivial to support it. These
two changes are a requirement of the gdb::optional unit testing patch
that will follow.

C++-ify gdb/xml-support.c a bit to eliminate cleanups
Basically convert cleanups to destructors in gdb_xml_parser and

Make inferior a class with cdtors, and use new/delete
struct inferior became a non-POD when enum_flags was made a non-POD,
so we should be allocating/destroying inferiors with new/delete, etc.

Note: this commit makes all boolean fields of inferior be "bool",
except the "detaching" field. That'll require more work, so I split
it to a separate patch.

watch_command_1: Fix dangling frame access
While working on some changes to switch_to_thread, I inadvertently
make switch_to_thread call reinit_frame_cache more frequently, even
when the thread didn't change. This exposed a latent bug in
watch_command_1, where we're referencing a frame after
creating/inserting breakpoints, which potentially calls
reinit_frame_cache if it needs to install breakpoints with a different
thread selected.
Handle this similarly to how it's already handled in other similar
cases. I.e., save any frame-related information we might need before
creating a breakpoint.

fork-child.c: Avoid unnecessary heap-allocation / string copying
The previous change to fork-child.c converted the argv building from
an alloca-allocated array of non-owning arg pointers, to a std::vector
of owning pointers, which results in N string dups, with N being the
number of arguments in the vector, and then requires manually
releasing the pointers owned by the vector.
This patch makes the vector hold non-owning pointers, and avoids the
string dups, by doing one single string copy of the arguments upfront,
and replacing separators with NULL terminators in place, like we used
to. All the logic to do that is encapsulated in a new class.
With this, there's no need to remember to manually release the argv
elements with free_vector_argv either.

* fork-child.c (execv_argv): New class.

XCNEW gdbarch_tdep in rl78 and rx
"struct gdbarch_tdep" is XNEW'ed in rl78 and rx, so the memory is not
cleared. As the result, tdep->rl78_psw_type is never initialized
properly.
struct gdbarch_tdep *tdep = gdbarch_tdep (gdbarch);
if (tdep->rl78_psw_type == NULL)
{
tdep->rl78_psw_type = arch_flags_type (gdbarch,
"builtin_type_rl78_psw", 1);
The bug is found by my unit test in the following patch.

* rl78-tdep.c (rl78_gdbarch_init): Use XCNEW instead of XNEW.
* rx-tdep.c (rx_gdbarch_init): Likewise.

breakpoint.c: bp_location (the array) shadows bp_location (the type)
The bp_location array has the same name as the "struct bp_location",
type preventing refering to the structure without the "struct" inside
breakpoint.c. I.e., we must write:
"new struct bp_location;"
instead of:
"new bp_location"
Rename the array and the associated variables/functions to avoid the
shadowing.

Create gdb_termios.h (and cleanup gdb/{,gdbserver/}terminal.h)
As requested, I'm sending this as a separate patch because it is ready
to be included as-is.
The idea here is that both gdb/terminal.h and gdb/gdbserver/terminal.h
share the same code, which is responsible for setting a bunch of
defines on based on the presence of termios.h and a few other headers.
This simple patch just moves this common code to common/gdb_termios.h
and makes the necessary adjustments on both GDB and gdbserver so that
they can use this new header. It also implements the some header
checks on common/common.m4.
As a bonus, gdb/gdbserver/terminal.h can be removed because it's now
empty.
Built on x86_64, no regressions found.

This removes make_cleanup_delete_event_location and instead changes

dead, because "location != NULL" can never be true in that branch; but

gdb: Move DJGPP/go32 bits to their own tdep file
I posit that this makes them easier to find.
The other day while working on the wchar_t patch, I had a bit of
trouble finding the DJGPP/go32 tdep bits. My initial reaction was
looking for a go32-specific tdep file, but there's none.
Confirmed that a --host=i586-pc-msdosdjgpp GDB still builds
successfully and includes the i386-go32-tdep.o object.
Confirmed that an --enable-targets=all build of GDB on x86-64
GNU/Linux includes the DJGPP/go32 bits too.

Teach GDB that wchar_t is a built-in type in C++ mode
GDB is currently not aware that wchar_t is a built-in type in C++
mode. This is usually not a problem because the debug info describes
the type, so when you have a program loaded, you don't notice this.
However, if you try expressions involving wchar_t before a program is
loaded, gdb errors out:
(gdb) p (wchar_t)-1
No symbol table is loaded. Use the "file" command.
(gdb) p L"hello"
No type named wchar_t.
(gdb) ptype L"hello"
No type named wchar_t.
This commit teaches gdb about the type. After:
(gdb) p (wchar_t)-1
$1 = -1 L'\xffffffff'
(gdb) p L"hello"
$2 = L"hello"
(gdb) ptype L"hello"
type = wchar_t [6]
Unlike char16_t/char32_t, unfortunately, the underlying type of
wchar_t is implementation dependent, both size and signness. So this
requires adding a couple new gdbarch hooks.
I grepped the GCC code base for WCHAR_TYPE and WCHAR_TYPE_SIZE, and it
seems to me that the majority of the ABIs have a 4-byte signed
wchar_t, so that's what I made the default for GDB too. And then I
looked for which ports have a 16-bit and/or unsigned wchar_t, and made
GDB follow suit.

Fix PR c++/21323: GDB thinks char16_t and char32_t are signed in C++
While the C++ standard says that char16_t and char32_t are unsigned types:
Types char16_t and char32_t denote distinct types with the same size,
signedness, and alignment as uint_least16_t and uint_least32_t,
respectively, in <cstdint>, called the underlying types.
... gdb treats them as signed currently:
(gdb) p (char16_t)-1
$1 = -1 u'\xffff'
There are actually two places in gdb that hardcode these types:
- gdbtypes.c:gdbtypes_post_init, when creating the built-in types,
seemingly used by the "x /s" command (judging from commit 9a22f0d0).
- dwarf2read.c, when reading base types with DW_ATE_UTF encoding
(which is what is used for these types, when compiling for C++11 and
up). Despite the comment, the type created does end up used.
Both places need fixing. But since I couldn't tell why dwarf2read.c
needs to create a new type, I've made it use the per-arch built-in
types instead, so that the types are only created once per arch
instead of once per objfile. That seems to work fine.
While writting the test, I noticed that the C++ language parser isn't
actually aware of these built-in types, so if you try to use them
without a program that uses them, you get:
(gdb) set language c++
(gdb) ptype char16_t
No symbol table is loaded. Use the "file" command.
(gdb) ptype u"hello"
No type named char16_t.
(gdb) p u"hello"
No type named char16_t.
That's fixed by simply adding a couple entries to C++'s built-in types
array in c-lang.c. With that, we get the expected:
(gdb) ptype char16_t
type = char16_t
(gdb) ptype u"hello"
type = char16_t [6]
(gdb) p u"hello"
$1 = u"hello"

C++-fy and prepare for sharing fork_inferior
As a preparation for the next patch, which will move fork_inferior
from GDB to common/ (and therefore share it with gdbserver), it is
interesting to convert a few functions to C++.
This patch touches functions related to parsing command-line arguments
to the inferior (see gdb/fork-child.c:breakup_args), the way the
arguments are stored on fork_inferior (using std::vector instead of
char **), and the code responsible for dealing with argv also on
gdbserver.
I've taken this opportunity and decided to constify a few arguments to
fork_inferior/create_inferior as well, in order to make the code
cleaner. And now, on gdbserver, we're using xstrdup everywhere and
aren't checking for memory allocation failures anymore, as requested
by Pedro:

IMO this refactoring was very good to increase the readability of the
code as well, because some parts of the argument handling were
unnecessarily confusing before.

This patch fixes the issue by deleting thread_info object if it is
deletable, otherwise, mark it as exited (by set_thread_exited).
Function set_thread_exited is shared from delete_thread_1. This patch
also moves field "refcount" to private and methods incref and
decref. Additionally, we stop using "ptid_t" in
"struct current_thread_cleanup" to reference threads, instead we use
"thread_info" directly. Due to this change, we don't need
restore_current_thread_ptid_changed anymore.

Class-ify ptid_t
I grew a bit tired of using ptid_get_{lwp,pid,tid} and friends, so I decided to
make it a bit easier to use by making it a proper class. The fields are now
private, so it's not possible to change a ptid_t field by mistake.
The new methods of ptid_t map to existing functions/practice like this:
ptid_t (pid, lwp, tid) -> ptid_build (pid, lwp, tid)
ptid_t (pid) -> pid_to_ptid (pid)
ptid.is_pid () -> ptid_is_pid (ptid)
ptid == other -> ptid_equal (ptid, other)
ptid != other -> !ptid_equal (ptid, other)
ptid.pid () -> ptid_get_pid (ptid)
ptid.lwp_p () -> ptid_lwp_p (ptid)
ptid.lwp () -> ptid_get_lwp (ptid)
ptid.tid_p () -> ptid_tid_p (ptid)
ptid.tid () -> ptid_get_tid (ptid)
ptid.matches (filter) -> ptid_match (ptid, filter)
I've replaced the implementation of the existing functions with calls to
the new methods. People are encouraged to gradually switch to using the
ptid_t methods instead of the functions (or we can change them all in
one pass eventually).
Also, I'm not sure if it's worth it (because of ptid_t's relatively
small size), but I have made the functions and methods take ptid_t
arguments by const reference instead of by value.
gdb/ChangeLog:
* common/ptid.h (struct ptid): Change to...
(class ptid_t): ... this.
<ptid_t>: New constructors.
<pid, lwp_p, lwp, tid_p, tid, is_pid, operator==, operator!=,

Fix Windows gdb build failure with Python 2 support
GDB fails to build for Windows host with Python 2 support enabled due
to PyFile_FromString's second argument being of type char * and being
passed a (const) string literal. This parameter is input only so this
commit fixes the issue by casting to char *.

ptid_{lwp,tid}_p: Remove unnecessary checks
The calls to ptid_equal in ptid_lwp_p and ptid_tid_p that compare the
argument to minus_one_ptid and null_ptid are not necessary. The calls
in question are:
if (ptid_equal (minus_one_ptid, ptid)
|| ptid_equal (null_ptid, ptid))
return 0;
minus_one_ptid is { .pid = -1, .lwp = 0, .tid = 0 }
null_ptid is { .pid = 0, .lwp = 0, .tid = 0 }
If the ptid argument is either of them, the statements
return (ptid_get_lwp (ptid) != 0);
and
return (ptid_get_tid (ptid) != 0);
will yield the same result (0/false).

* common/ptid.c (ptid_lwp_p, ptid_tid_p): Remove comparison with
minus_one_ptid and null_ptid.

-Wwrite-strings: Fix Solaris "set procfs-file"
Compiling GDB with -Wwrite-strings flags this code in gdb/proc-api.c:
static char *procfs_filename = "procfs_trace";
as needing a cast. However, this variable is a command variable, and
as such it's incorrect to initialize it to a literal, since when you
use the corresponding set command, gdb frees the old string...
I didn't manage to fully build Solaris gdb (fails for other reasons),
but I confirmed that the system GDB on Solaris 11 crashes when running
this command:
(gdb) set procfs-file foo
Segmentation Fault (core dumped)
So I don't think this commit can make it worse than the status quo.
gdb/ChangeLog:
2017-04-05 Pedro Alves <palves@redhat.com>
* proc-api.c (procfs_filename): Don't initialize
procfs_filename.
(prepare_to_trace): Assume procfs_filename is non-NULL.
(_initialize_proc_api): Give procfs_filename a default value here.

-Wwrite-strings: Some constification in gdb/breakpoint.c
The main motivation here is avoiding having to write a couple casts
like these:
if (!arg)
- arg = "";
+ arg = (char *) "";
in catch_exception_command_1 and catch_exec_command_1.
That requires making ep_parse_optional_if_clause and
check_for_argument take pointers to const strings. I then tried
propagating the resulting constification all the way, but that was
spiraling out of control, so instead I settled for keeping const and
non-const overloads.

-Wwrite-strings: execute_command calls with string literals
This is ugly, but it's just making the uglyness explicit.
All these places would better be calling some API function directly
instead of going through execute_command & friends...

call.

-Wwrite-strings: Add a PyArg_ParseTupleAndKeywords "const char *" overload
-Wwrite-strings flags code like:
static char *keywords[] = {"command", "from_tty", "to_string", NULL };
as needing "(char *)" casts, because string literals are "const char []".
We can get rid of the casts by changing the array type like this:
- static char *keywords[] = {"command", "from_tty", "to_string", NULL };
+ static const char *keywords[] = {"command", "from_tty", "to_string", NULL };
However, passing the such array to PyArg_ParseTupleAndKeywords no longer
works OOTB, because PyArg_ParseTupleAndKeywords expects a "char **":
PyArg_ParseTupleAndKeywords(PyObject *args, PyObject *kw,
const char *format,
char *keywords[], ...);
and "const char **" is not implicitly convertible to "char **". C++
is more tolerant that C here WRT aliasing, and a const_cast<char **>
is fine. However, to avoid having all callers do the cast themselves,
this commit defines a gdb_PyArg_ParseTupleAndKeywords function here
with a corresponding 'keywords' parameter type that does the cast in a
single place.

-Wwrite-strings: Wrap PyGetSetDef for construction with string literals
Unfortunately, PyGetSetDef's 'name' and 'doc' members are 'char *'
instead of 'const char *', meaning that in order to list-initialize
PyGetSetDef arrays using string literals requires writing explicit
'char *' casts. For example:
static PyGetSetDef value_object_getset[] = {
- { "address", valpy_get_address, NULL, "The address of the value.",
+ { (char *) "address", valpy_get_address, NULL,
+ (char *) "The address of the value.",
NULL },
- { "is_optimized_out", valpy_get_is_optimized_out, NULL,
- "Boolean telling whether the value is optimized "
+ { (char *) "is_optimized_out", valpy_get_is_optimized_out, NULL,
+ (char *) "Boolean telling whether the value is optimized "
"out (i.e., not available).",
NULL },
- { "type", valpy_get_type, NULL, "Type of the value.", NULL },
- { "dynamic_type", valpy_get_dynamic_type, NULL,
- "Dynamic type of the value.", NULL },
- { "is_lazy", valpy_get_is_lazy, NULL,
- "Boolean telling whether the value is lazy (not fetched yet\n\
+ { (char *) "type", valpy_get_type, NULL,
+ (char *) "Type of the value.", NULL },
+ { (char *) "dynamic_type", valpy_get_dynamic_type, NULL,
+ (char *) "Dynamic type of the value.", NULL },
+ { (char *) "is_lazy", valpy_get_is_lazy, NULL,
+ (char *) "Boolean telling whether the value is lazy (not fetched yet\n\
from the inferior). A lazy value is fetched when needed, or when\n\
the \"fetch_lazy()\" method is called.", NULL },
{NULL} /* Sentinel */
We have ~20 such arrays, and I first wrote a patch that fixed all of
them like that... It's not pretty...
One way to make these a bit less ugly would be add a new macro that
hides the casts, like:
#define GDBPY_GSDEF(NAME, GET, SET, DOC, CLOSURE) \
{ (char *) NAME, GET, SET, (char *) DOC, CLOSURE }
and then use it like:
static PyGetSetDef value_object_getset[] = {
GDBPY_GSDEF ("address", valpy_get_address, NULL,
"The address of the value.", NULL),
GDBPY_GSDEF ("is_optimized_out", valpy_get_is_optimized_out, NULL,
"Boolean telling whether the value is optimized ", NULL),
{NULL} /* Sentinel */
};
But since we have C++11, which gives us constexpr and list
initialization, I thought of a way that requires no changes where the
arrays are initialized:
We add a new type that extends PyGetSetDef (called gdb_PyGetSetDef),
and add constexpr constructors that accept const 'name' and 'doc', and
then list/aggregate initialization simply "calls" these matching
constructors instead.
I put "calls" in quotes, because given "constexpr", it's all done at
compile time, and there's no overhead either in binary size or at run
time. In fact, we get identical binaries, before/after this change.
Unlike the fixes that fix some old Python API to match the API of more
recent Python, this switches to using explicit "gdb_PyGetSetDef"
everywhere, just to be clear that we are using our own version of it.

-Wwrite-strings: Constify word break character arrays
-Wwrite-strings flags several cases of missing casts around
initializations like:
static char *gdb_completer_command_word_break_characters =
" \t\n!@#$%^&*()+=|~`}{[]\"';:?/>.<,";
Obviously these could/should be const. However, while at it, there's
no need for these variables to be pointers instead of arrays. They
are never changed to point to anything else.
Unfortunately, readline's rl_completer_word_break_characters is
"char *", not "const char *". So we always need a cast somewhere. The
approach taken here is to add a new
set_rl_completer_word_break_characters function that becomes the only
place that writes to rl_completer_word_break_characters, and thus the
single place that needs the cast.

-Wwrite-strings: Don't initialize string command variables to empty string
-Wwrite-strings flags these initializations as requiring a cast.
However, these variables are command variables, and as such point to
heap-allocated memory. The initial allocation is always done when the
corresponding command is registered. E.g.,:
dprintf_function = xstrdup ("printf");
add_setshow_string_cmd ("dprintf-function", class_support,
&dprintf_function, _("\
Set the function to use for dynamic printf"), _("\
Show the function to use for dynamic printf"), NULL,
update_dprintf_commands, NULL,
&setlist, &showlist);
That's why we never reach a bogus attempt to free these string
literals.
So, just drop the incorrect initializations.

Initialize gdb::optional empty payload to quiet false -Wmaybe-uninitialized warnings
Commit ecfb656c37b982 ("dwarf2read.c: Make dir_index and
file_name_index strong typedefs") added a use of gdb::optional that
triggers bogus -Wmaybe-uninitialized warnings:
GCC trunk is complaining like this:
../../binutils-gdb/gdb/dwarf2read.c: In function void read_formatted_entries(bfd*, const gdb_byte**, line_header*, const comp_unit_head*, void (*)(line_header*, const char*, dir_index, unsigned int, unsigned int)):

../../binutils-gdb/gdb/dwarf2read.c:17779:65: error: fe.file_entry::name may be used uninitialized in this function [-Werror=maybe-uninitialized]
While some older GCCs are complaining like this:
../../binutils-gdb/gdb/dwarf2read.c: In function void read_formatted_entries(bfd*, const gdb_byte**, line_header*, const comp_unit_head*, void (*)(line_header*, const char*, dir_index, unsigned int, unsigned int)):

callback (lh, fe.name, fe.d_index, fe.mod_time, fe.length);
Looking around the web, I see that boost's optional implementation
triggers this kind of issue often too. See:
http://www.boost.org/doc/libs/1_63_0/libs/optional/doc/html/boost_optional/tutorial/gotchas/false_positive_with__wmaybe_uninitialized.html
I noticed that replacing the gdb::optional uses with real C++17
std::optional uses against GCC 7/trunk makes the warnings go away.
Looking at the implementation, AFAICS, libstdc++ always initializes
its "empty" union payload member (_M_empty, which is defined as an
empty class, like ours). I.e., all payload types have this ctor:
struct _Optional_payload.....
{
constexpr _Optional_payload()
: _M_empty() {}
The constexpr makes a diference too. Without it, GCC7 still warns.
So I'm applying the same treatment to our gdb::optional.

PR ld/21233: Avoid sweeping forced-undefined symbols in section GC
Complement commit 902e9fc76a0e ("PR ld/20828: Move symbol version
processing ahead of GC symbol sweep"), commit b531344c34b0 ("PR
ld/20828: Reorder the symbol sweep stage of section GC") and commit
81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced
local with section GC"), and prevent symbols forcibly entered in the
output file with the use of the `--undefined=' or `--require-defined='
linker command line options or the EXTERN linker script command from
being swept in section garbage collection and consequently recorded in
the dynamic symbol table as local entries. This happens in certain
circumstances, where a symbol reference also exists in one of the static
input files, however only in a section which is garbage-collected and
does not make it to the output file, and the symbol is defined in a
dynamic object present in the link.
For example with the `i386-linux' target and the `pr21233.s' and
`pr21233-l.s' sources, and the `pr21233.ld' linker script included with
this change we get:
$ as -o pr21233-l.o pr21233-l.s
$ ld -shared -T pr21233.ld -o libpr21233.so pr21233-l.o
$ as -o pr21233.o pr21233.s
$ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so
$ readelf --dyn-syms pr21233
Symbol table '.dynsym' contains 2 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 00000000 0 OBJECT LOCAL DEFAULT UND bar
$
which makes the run-time `bar' dependency of the `pr21233' executable
different from its corresponding link-time dependency, i.e. the presence
of `libpr21233.so' and its `bar' symbol is required at the link time,
however at the run time a copy of `libpr21233.so' without `bar' will do.
Similarly with `--undefined=' and EXTERN which do not actually require
the reference to the symbol requested to be satisfied with a definition
at the link time, however once the definition has been pulled at the
link time, so it should at the dynamic load time.
Additionally with the `mips-linux' target we get:
$ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so
ld: BFD (GNU Binutils) 2.28.51.20170324 assertion fail .../bfd/elfxx-mips.c:3861
$
as the target is not prepared to handle such a local dynamic symbol.
With this change in effect we get:
$ readelf --dyn-syms pr21233
Symbol table '.dynsym' contains 2 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 00000000 0 OBJECT GLOBAL DEFAULT UND bar
$
instead, for both targets.

this library has not been used as the default library since FreeBSD
5.0 (2003) and 4.11 (2005). Thread support for modern FreeBSD binaries
is provided via "normal" LWP support in core files and the native
FreeBSD target.

dwarf2read.c: C++fy lnp_state_machine
While I was looking at the file, I noticed that this struct could be
nicely converted to a class. As I was progressing, I ended up moving
all state machine actual internal state manipulation to methods of
lnp_state_machine, essentially decoupling DWARF parsing from state
tracking. I also noticed that the lnp_reader_state doesn't really
serve any good use, so that's eliminated in the process.

Make sect_offset and cu_offset strong typedefs instead of structs
A while ago, back when GDB was a C program, the sect_offset and
cu_offset types were made structs in order to prevent incorrect mixing
of those offsets. Now that we require C++11, we can make them
integers again, while keeping the safety, by exploiting "enum class".
We can add a bit more safety, even, by defining operators that the
types _should_ support, helping making the suspicious uses stand out
more.
Getting at the underlying type is done with the new to_underlying
function added by the previous patch, which also helps better spot
where do we need to step out of the safety net. Mostly, that's around
parsing the DWARF, and when we print the offset for complaint/debug
purposes. But there are other occasional uses.
Since we have to define the sect_offset/cu_offset types in a header
anyway, I went ahead and generalized/library-fied the idea of "offset"
types, making it trivial to add more such types if we find a use. See
common/offset-type.h and the DEFINE_OFFSET_TYPE macro.
I needed a couple generaly-useful preprocessor bits (e.g., yet another
CONCAT implementation), so I started a new common/preprocessor.h file.
I included units tests covering the "offset" types API. These are
mostly compile-time tests, using SFINAE to check that expressions that
shouldn't compile (e.g., comparing unrelated offset types) really are
invalid and would fail to compile. This same idea appeared in my
pending enum-flags revamp from a few months ago (though this version
is a bit further modernized compared to what I had posted), and I plan
on reusing the "check valid expression" bits added here in that
series, so I went ahead and defined the CHECK_VALID_EXPR macro in its
own header -- common/valid-expr.h. I think that's nicer regardless.
I was borderline between calling the new types "offset" types, or
"index" types, BTW. I stuck with "offset" simply because that's what
we're already calling them, mostly.

dwarf2read.c: Make dir_index and file_name_index strong typedefs
This should help catch mistakes related to mixing the 1-based DWARF
indexes with 0-based std::vector indexes, since the new types do not
implicitly convert to anything.
The change in read_formatted_entries relates to the fact that doing
the seemingly simpler:
- uintp = &fe.dir_index;
+ uintp = (unsigned int *) &fe.dir_index;
would be undefined C/C++. So to address that, I made the function
extract the form before assigning to the file_entry. It felt natural
to use gdb::optional for "do I have this value", and this is what
motivated the previous patch that added the missing observer methods
to gdb::optional.

dwarf2read.c: Some C++fycation, use std::vector, std::unique_ptr
This starts off as replacing a couple custom open coded vector

off of that. I.e., use new/delete instead of XCNEW/xfree, add
ctors/dtors/initializers where appropriate. And then use
std::unique_ptr instead of cleanups. Some functions became methods,
and in a couple spots, some single-use callback functions that would
have to be tweaked anyway are converted to lambdas instead.

Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX
Mark an ALLOC section, which should be placed in special memory area,
with SHF_GNU_MBIND. Its sh_info field indicates the special memory
type. GNU_MBIND section names start with ".mbind" so that they are
placed as orphan sections by linker. All input GNU_MBIND sections
with the same sh_type, sh_flags and sh_info are placed in one output
GNU_MBIND section. In executable and shared object, create a
GNU_MBIND segment for each GNU_MBIND section and its segment type is
PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is
aligned at page boundary.
The assembler syntax:
.section .mbind.foo,"adx",%progbits
^ 0: Special memory type.
|
'd' for SHF_GNU_MBIND.
.section .mbind.foo,"adx",%progbits,0x1
^ 1: Special memory type.
|
'd' for SHF_GNU_MBIND.
.section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2
^ 2: Special memory type.
|
'd' for SHF_GNU_MBIND.

gdbserver: Clear .deps on clean
In some situations, the dependency tracking files in .deps can refer to
source files that were removed or renamed, leading to errors like:
make: *** No rule to make target `version.c', needed by `version.o'. Stop.
This patch makes the clean target clear the .deps directory, which gives
the user a chance to recover from the error wihtout knowing about the
internals of the build system.
It is already done for GDB. See here for more details:

ld: Support ELF GNU program properties
From .note.gnu.property section in each ELF input, we build a list of
GNU properties if .note.gnu.property section isn't corrupt. The unknown
properties are ignored. All property lists in relocatable inputs are
merged into an output property list. When -z stack-size=N is used and
N isn't 0, the GNU_PROPERTY_STACK_SIZE property will be merged with or
added to the output property list. .note.gnu.property section is
generated in output from the output property list.

gdbserver: Suffix generated C files with -generated
I noticed that there were some missing files in gdbserver's gitignore
(some generated register format .c files). Of course the easy fix would
be to add those files to .gitignore, but I think we can do a better job,
so that we don't have to worry about adding generated files to
.gitignore or the clean Makefile target.
I suggest naming all generated source files -generated.c. This way, we
can use a single rule in .gitignore and do a "rm -f *-generated.c" to
clean them up.
New in v2:
- Don't rename version.o and xml-builtin.o

commit 662659a1a582af14aa45a458005e2a4df514b6d7
Author: Iain Buclaw <ibuclaw@gdcproject.org>

Fix classification of `module.type' in D lexer.
The two-tier lexer in gdb/d-exp.y, which resolves fully qualified names
missed a case where `module.type' was not being classified as one token.
And so when the grammar takes over, it matched the remaining tokens
against the rule `TypeExp . IdentifierExp', where we were expecting to
instead match cast expression `( TypeExp ) UnaryExpression'.
Adding a case for TYPE_CODE_MODULE in type_aggregate_p means that
classify_inner_name will get a chance to lookup the symbol.
This was noticed when using `watch -l', and got the rather confusing
response:
A syntax error in expression, near `) 0x0add4e55'.
So it's been included in the testsuite, along with another test that
does effectively the same expression, but explicitly.

* d-exp.y (type_aggregate_p): Treat TYPE_CODE_MODULE as being
aggregate-like.
gdb/testsuite/ChangeLog:
* gdb.dlang/watch-loc.c: New file.

Add a prologue analysis that recognizes all instructions that may happen in
compiler-generated prologue, including various stores, core register moves,
subtraction and ENTER_S instruction that does a lot of prologue actions through
microcode.
Testcases cover various prologue scenarios, including instructions that are
spread across multiple 16-bit encodings (for example there are 7 encodings of
store instruction).

arc: Add disassembler helper
Add disassembler helper for GDB, that uses opcodes structure arc_instruction
and adds convenience functions to handle instruction operands. This interface
solves at least those problems with arc_instruction:
* Some instructions, like "push_s", have implicit operands which are not
directly present in arc_instruction.
* Operands of particular meaning, like branch/jump targets, have various
locations and meaning depending on type of branch/target.
* Access to operand value is abstracted into a separate function, so callee
code shouldn't bother if operand value is an immediate value or in a
register.
Testcases included in this commit are fairly limited - they test exclusively
branch instructions, something that will be used in software single stepping.
Most of the other parts of this disassembler helper are tested during prologue
analysis testing.

gdb/cp-name-parser.y: Eliminate make_empty, use cplus_demangle_fill_component
The demangler exports the cplus_demangle_fill_component function that
clients should use to initialize demangle_component components that
use the "s_binary" union member. cp-name-parser.y uses it in some
places, via the fill_comp wrapper, but not all. Several places
instead use a GDB-specific "make_empty" function. Because this
function does not call any of the demangler "fill" functions, we had
to patch it recently to clear the allocated demangle_component's
"d_printing" field, which is supposedly a "private" demangler field.
To avoid such problems in the future, this commit switches those
places to use "fill_comp" instead, and eliminates the "make_empty"
function.

about rvalue references, and a change to make it use
cplus_demangle_fill_component more ran into an assertion because of
this.

Fix gdb_xml_debug/gdb_xml_error ATTRIBUTE_PRINTF use
The declarations of gdb_xml_debug and gdb_xml_error are passing "0" as
"first-to-check" argument to ATTRIBUTE_PRINTF, as if they were va_args
functions. Consequently, the arguments to gdb_xml_debug /
gdb_xml_error aren't being checked against the format strings.
With that fixed, a couple obvious bugs are exposed, both fixed by this

Remove some unnecessary inferior_ptid setting/restoring when fetching/storing registers
Now that the to_fetch_registers, to_store_registers and
to_prepare_to_store target methods don't rely on the value of
inferior_ptid anymore, we can remove a bunch of now unnecessary setting
and restoring of inferior_ptid.
The asserts added recently in target_fetch_registers and
target_store_registers, which validate that inferior_ptid matches the
regcache's ptid, must go away. It's the whole point of this effort, to
not require inferior_ptid to have a particular value when calling these
functions.
One thing that I noticed is how sol-thread.c's ps_lgetregs and friends
use the current value of inferior_ptid instead of what's passed as
argument (ph->ptid), unlike proc-service.c's versions of the same
functions. Is it expected? I left it like this in the current patch,
but unless there's a good reason for it to be that way, I guess we
should make it use the parameter.

* fbsd-tdep.c (fbsd_corefile_thread): Don't set/restore
inferior_ptid.

Remove constness of libdir in do_start_initialization
The patch "Fix memory leak in python.c:do_start_initialization"
(https://sourceware.org/ml/gdb-patches/2017-03/msg00407.html) introduced a
compilation error on some platforms:
../../binutils-gdb/gdb/python/python.c: In function bool do_start_initialization():
../../binutils-gdb/gdb/python/python.c:1556:16: error: invalid conversion from const void* to void* [-fpermissive]

Fix memory leak in python.c:do_start_initialization
When intializing Python the path to the python binary is build the
following way
progname = concat (ldirname (python_libdir), SLASH_STRING, "bin",
SLASH_STRING, "python", (char *) NULL);
This is problematic as both concat and ldirname allocate memory for the
string they return. Thus the memory allocated by ldirname cannot be
accessed afterwards causing a memory leak. Fix it by temporarily storing
libdir in a variable and xfree it after concat.

gas: xtensa: make trampolines relaxation work with jumps in slots other than 0
add_jump_to_trampoline assumes that jump instruction is in slot 0,
when it's in other slot that results in fixup that references NULL symbol,
which results in segfault later in xtensa_make_cached_fixup.
Search for the non-NULL symbol in the tc_frag_data.slot_symbols and check
that there's exactly one such slot.
xtensa_relax_frag for RELAX_TRAMPOLINE reassigns fixup from the original
instruction with jump to generated jump in the trampoline frag, but does not
fix its fx_r_type or fx_size. That results in "undecodable fix" or
"fixup not contained within frag" error messages during relaxation.
Fix both these fields.

Remove lwp -> pid conversion in linux_nat_xfer_partial
The linux_nat_xfer_partial does a conversion of inferior_ptid: if it's
an LWP (ptid::lwp != 0), it builds a new ptid with the lwp as
the pid and assigns that temporarily to inferior_ptid. For example, if
inferior_ptid is:
{ .pid = 1234, .lwp = 1235 }
it will assign this to inferior_ptid for the duration of the call:
{ .pid = 1235, .lwp = 0 }
Instead of doing this, this patch teaches the inf-ptrace implementation
of xfer_partial to deal with ptids representing lwps by using
get_ptrace_pid.
Also, in linux_proc_xfer_spu and linux_proc_xfer_partial, we use ptid_get_lwp
instead of ptid_get_pid. While not strictly necessary, since the content of
/proc/<pid> and /proc/<lwp> should be the same, it's a bit safer, because:
- some files under /proc/<pid>/ may not work if the <pid> thread is
running, just like ptrace requires a stopped thread. The current
thread's lwp id is more likely to be in the necessary state (stopped).
- if the leader (<pid>) had exited and is thus now zombie, then several
files under "/proc/<pid>" won't work, while they will if you use
"/proc/<lwp>".
The testsuite found no regression on native amd64 linux.
gdb/ChangeLog:
* inf-ptrace.c (inf_ptrace_xfer_partial): Get pid from ptid
using get_ptrace_pid.
* linux-nat.c (linux_nat_xfer_partial): Don't set/restore
inferior_ptid.
(linux_proc_xfer_partial, linux_proc_xfer_spu): Use lwp of
inferior_ptid instead of pid.

Wrap locally used classes in anonymous namespace
Both aarch64-tdep.c and arm-tdep.c defines a class instruction_reader, which
violates ODR, but linker doesn't an emit error. I fix this issue by wrapping
them by anonymous namespace, but I think it is better to apply this for all
locally used classes.
If it is a good idea to put locally used class into anonymous namespace, we
should document this rule into GDB coding convention, or even GCC coding
convention. Note that anonymous namespace has been used in GCC but GCC
coding convention doesn't mention the it.

windows: Use ptid from regcache in register fetch/store
Use the ptid from the regcache so we don't depend on the current value
of the inferior_ptid global.
Also, change how the current thread is passed to sub-functions. The
windows_fetch_inferior_registers function sets current_thread then calls
do_windows_fetch_inferior_registers, which reads current_thread. This
very much looks like passing a parameter through a global variable. I
think it would be more straightforward to pass the thread as a
parameter.
gdb/ChangeLog:
* windows-nat.c (do_windows_fetch_inferior_registers): Add
windows_thread_info parameter and use it instead of

Add rvalue reference tests and docs
This patch adds tests for the initial rvalue reference support patchset. All
of the new tests are practically mirrored regular references tests and, except
for the demangler ones, are introduced in new files, which are set to be
compiled with -std=gnu++11. Tested are printing of rvalue reference types and
values, rvalue reference parameters in function overloading, demangling of
function names containing rvalue reference parameters, casts to rvalue
reference types, application of the sizeof operator to rvalue reference types
and values, and support for rvalue references within the gdb python module.

Add rvalue references to overloading resolution
This patch introduces changes to rank_one_type() dealing with ranking an rvalue
reference type when selecting a best viable function from a set of candidate
functions. The 4 new added rules for rvalue references are:
1) An rvalue argument cannot be bound to a non-const lvalue reference parameter
and an lvalue argument cannot be bound to an rvalue reference parameter.
[C++11 13.3.3.1.4p3]
2) If a conversion to one type of reference is an identity conversion, and a
conversion to the second type of reference is a non-identity conversion, choose
the first type. [C++11 13.3.3.2p3]
3) An rvalue should be first tried to bind to an rvalue reference, and then to
an lvalue reference. [C++11 13.3.3.2p3]
4) An lvalue reference to a function gets higher priority than an rvalue
reference to a function. [C++11 13.3.3.2p3]
This patch is not exactly correct. See c++/15372 for tracking overload
resolution bugs.

Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

Add -file-list-shared-libraries MI command
This change adds the MI equivalent for the "info sharedlibrary"
command. The command was already partially documented but ignored as
it was not implemented. The new MI command works similarly to the CLI
command, taking an optional regular expression as an argument and
outputting the library information.
I included a test for the new command in mi-solib.exp.

Fix spurious FAILs with examine-backward.exp
The test case examine-backward.exp issues the command "x/-s" after the end
of the first string in TestStrings, but without making sure that this
string is preceded by a string terminator. Thus GDB may spuriously print
some random characters from before that string, and then the test fails.
This patch assures that TestStrings is preceded by a string terminator.

readelf: Don't error on .debug files with NOBITS .dynamic section.
The fix for PR binutils/17512 added a check for the dynamic segment being
inside the actual ELF file. If not an error message would be produced:
readelf: Error: the dynamic segment offset + size exceeds the size of the file
Unfortunately for separate debuginfo files it is common for the dynamic
segment not being inside the file because the .dynamic section is NOBITS.
Since the check is done unconditionally in process_program_headers and
process_program_headers is always called (to setup dynamic_addr in case
it is needed). The error is produced on any operations done on any .debug
file (even if no program headers or the dynamic segment is used).
If there are section headers then a cross check is done to see if the
.dynamic section is NOBITS in which case dynamic_addr is set to zero
without a warning or error (which is then checked first before any
operation on the dynamic segement is done).
Move the check for the dynamic segment being inside the actual ELF file
after the cross check with the section headers to suppress the error for
.debug files.
binutils/ChangeLog:
* readelf.c (process_program_headers): Move dynamic_addr check
after .dynamic section cross check.

s390: Fix displaced-stepping certain relative branch insns
On s390x targets GDB can not handle displaced stepping correctly for some
relative branch instructions, such as cij (compare immediate and branch
relative). When setting a breakpoint on such an instruction and
single-stepping over it, the branch is never taken. This is because the
check in s390_displaced_step_fixup for relative branch instructions is
incomplete.
Instead of completing the list of relative branch instructions to check
against, this patch just treats relative branches and non-branching
instructions in the same way and adjusts the PC with the negated
displacement in both cases.
gdb/ChangeLog:
* s390-linux-tdep.c (is_rsi, is_rie): Remove functions.
(s390_displaced_step_fixup): Cover relative branches with the

Nick pointed out that I hadn't documented the new -mfpu option
neon-vfpv3 and mentioned that some others were missing.
Having looked through the list only one (neon-fp16) really should be
documented; the other two entries in the real table should not be

This patch adds the missing entries and notes in the main table that

DT_TEXTREL vs IFUNC
If you should somehow link non-pic objects into a PIE or shared
library, resulting in an object with DT_TEXTREL (text relocations)
set, and your executable or shared library also contains GNU indirect
functions, then you're in trouble. To apply dynamic relocations
ld.so will make the text segment writable. On most systems this will
make the text segment non-executable, which will then result in a
segfault when ld.so tries to run ifunc resolvers when applying
relocations against ifuncs.
This patch teaches PowerPC ld to detect the situation, and warn.

PR remote/21188: Fix remote serial timeout
As Gareth McMullin <gareth@blacksphere.co.nz> reports at
<https://sourceware.org/ml/gdb-patches/2017-02/msg00560.html>, the
timeout mechanism in ser-unix.c was broken by commit 048094acc
("target remote: Don't rely on immediate_quit (introduce quit
handlers)").
Instead of applying a local fix, and since we now finally always use
interrupt_select [1], let's get rid of hardwire_readchar entirely, and
use ser_base_readchar instead, which has similar timeout handling,
except for the bug.
Smoke tested with:
$ socat -d -d pty,raw,echo=0 pty,raw,echo=0
2017/03/14 14:08:13 socat[4994] N PTY is /dev/pts/14
2017/03/14 14:08:13 socat[4994] N PTY is /dev/pts/15
2017/03/14 14:08:13 socat[4994] N starting data transfer loop with FDs [3,3] and [5,5]
$ gdbserver /dev/pts/14 PROG
$ gdb PROG -ex "tar rem /dev/pts/15"
and then a few continues/ctrl-c's, plus killing gdbserver and socat.

Big-endian targets: Don't ignore offset into DW_OP_stack_value
Recently I fixed a bug that caused a DW_OP_implicit_pointer with non-zero
offset into a DW_OP_implicit_value to be handled incorrectly on big-endian
targets. GDB ignored the offset and copied the wrong bytes:
https://sourceware.org/ml/gdb-patches/2017-01/msg00251.html
But there is still a similar issue when a DW_OP_implicit_pointer points
into a DW_OP_stack_value instead; and again, the offset is ignored. There
is an important difference, though: While implicit values are treated like
blocks of data and anchored at the lowest-addressed byte, stack values
traditionally contain integer numbers and are anchored at the *least
significant* byte. Also, stack values do not come in varying sizes, but
are cut down appropriately when used. Thus, on big-endian targets the
scenario looks like this (higher addresses shown right):
|<- - - - - Stack value - - - - - - ->|
| |
|<- original object ->|
|
| offset ->|####|
^^^^
de-referenced
implicit pointer
(Note how the original object's size influences the position of the
de-referenced implicit pointer within the stack value. This is not the
case for little-endian targets, where the original object starts at offset
zero within the stack value.)
This patch implements the logic indicated in the above diagram and adds an
appropriate test case. A new function dwarf2_fetch_die_type_sect_off is
added; it is used for retrieving the original object's type, so its size
can be determined. That type is passed to dwarf2_evaluate_loc_desc_full
via a new parameter.
gdb/ChangeLog:
* dwarf2loc.c (indirect_synthetic_pointer): Get data type of
pointed-to DIE and pass it to dwarf2_evaluate_loc_desc_full.
(dwarf2_evaluate_loc_desc_full): New parameter subobj_type; rename

Fix arm process record for some instructions
I look at some fails in gdb.reverse/solib-precsave.exp in -mthumb,
they are caused by some bugs on decoding these three instructions,
uxtb, ldr and mrc. This patch adds unit tests against these three
instructions, and fix these bugs by re-organizing the code to match
the table in ARM ARM.

inf-ptrace: Do not stop memory transfers after a single word
When inf_ptrace_xfer_partial performs a memory transfer via ptrace with
PT_READ_I, PT_WRITE_I (aka PTRACE_PEEKTEXT, PTRACE_POKETEXT), etc., then
it currently transfers at most one word. This behavior yields degraded
performance, particularly if the caller has significant preparation work
for each invocation. And indeed it has for writing, in
memory_xfer_partial in target.c, where all of the remaining data to be
transferred is copied to a temporary buffer each time, for breakpoint
shadow handling. Thus large writes have quadratic runtime and can take
hours.
Note: On GNU/Linux targets GDB usually does not use
inf_ptrace_xfer_partial for large memory transfers, but attempts a single
read/write from/to /proc/<pid>/mem instead. However, the kernel may
reject writes to /proc/<pid>/mem (such as kernels prior to 2.6.39), or
/proc may not be mounted. In both cases GDB falls back to the ptrace
mechanism.
This patch fixes the performance issue by attempting to fulfill the whole
transfer request in inf_ptrace_xfer_partial, using a loop around the
ptrace call.

PR gdb/21220
* inf-ptrace.c (inf_ptrace_xfer_partial): In "case
TARGET_OBJECT_MEMORY", extract the logic for ptrace peek/poke...

An optional parameter TEST has been added to get_hexadecimal_valueof in commit:

This patch adds a similar optional parameter to other related methods that

linux-nat: Exploit /proc/<pid>/mem for writing
So far linux_proc_xfer_partial refused to handle write requests. This is
still based on the assumption that the Linux kernel does not support
writes to /proc/<pid>/mem. That used to be true, but has changed with
Linux 2.6.39 released in May 2011.
This patch lifts this restriction and now exploits /proc/<pid>/mem for
writing to inferior memory as well, if possible.

Add asserts in target_fetch/store_registers
We are currently assuming that regcache->ptid is equal to inferior_ptid
when we call target_fetch/store_registers. These asserts just validate
that assumption. Also, since the following patches will change target
code to use regcache->ptid instead of inferior_ptid, asserting that they
are the same should ensure that our changes don't have any unintended
consequences.
gdb/ChangeLog:
* target.c (target_fetch_registers, target_store_registers): Add
assert.

Introduce regcache_get_ptid
This patch introduces the regcache_get_ptid function, which can be used
to retrieve the ptid a regcache is connected to. It is used in
subsequent patches.

testsuite: Disable backslash_in_multi_line_command_test for old DejaGnus
I noticed that backslash_in_multi_line_command_test in
gdb.base/commands.exp failed on our RHEL6 servers. I traced it to the
old version of DejaGnu (1.4.4). I have found that instead of receiving
the expected:
"print \\\nargc\n"
gdb received:
"print argc\n"
thus breaking the test and its purpose. Versionof DejaGnu < 1.5 mess
up sending "\\\n", it somehow gets replaced with a space. I found that
the following commit in DejaGnu fixed the issue:
http://git.savannah.gnu.org/cgit/dejagnu.git/commit/lib/remote.exp?id=3f39294f5cd6802858838d3bcc0ccce847ae17f2
Even though the commit is almost 10 years old, the following release of
DejaGnu was only in 2013, which is why we still have systems with the
old code.
If the DejaGnu version is < 1.5, we just skip the test.
gdb/testsuite/ChangeLog:
* gdb.base/commands.exp (backslash_in_multi_line_command_test):
Skip for versions of DejaGnu < 1.5.

testsuite: Introduce dejagnu_version
The next patch will require checking the DejaGnu version. There is
already a test that does this,
gdb.threads/attach-many-short-lived-threads.exp. This patch introduces
a new procedure, dejagnu_version, and makes that test use it.
The version number is "right-padded" with zeroes, to make sure that we
always return a triplet (major, minor, patch).
The procedure does not consider the DejaGnu versions from git. For
example, if you used DejaGnu from its current master branch, the version
would be "1.6.1-git", meaning that 1.6.1 will be the next release. I
figured we'll cross that bridge when (and if) we get there.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (dejagnu_version): New proc.
* gdb.threads/attach-many-short-lived-threads.exp (bad_dejagnu):
Use dejagnu_version.

Merge libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.
While integrating the d_printing recursion guard change into gdb I
noticed we forgot to initialize the demangle_component d_printing
field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}.
As is done in cplus_demangle_fill_{component,builtin_type,operator}.
It happened to work because in gcc all demangle_components were
allocated through d_make_empty. But gdb has its own allocation
mechanism (as might other users).

c++/8218: Destructors w/arguments.
For a long time now, c++/8218 has noted that GDB is printing argument types
for destructors:
(gdb) ptype A
type = class A {
public:
~A(int);
}
This happens because cp_type_print_method_args doesn't ignore artificial
arguments. [It ignores the first `this' pointer because it simply skips
the first argument for any non-static function.]
This patch fixes this:
(gdb) ptype A
type = class A {
public:
~A();
}
I've adjusted gdb.cp/templates.exp to account for this and added a new
passing regexp.

ld: Track changes to default region LMA even for empty sections
Given a linker script fragment like this:
SECTIONS {
. = 0x1000;
.text : AT(0x100) { *(.text) }
.data : AT(0x200) { *(.data) }
.rodata : AT(0x300) { *(.rodata) }
}
and an input file containing sections, '.text', '.data.1', and
'.rodata', then we'd expect the linker to place '.text' and '.rodata' in
the obvious way, and the '.data.1' orphan section would be located after
the '.data' section (assuming similar section properties).
Further, I believe that the expectation would be that the LMA for the
orphan '.data.1' section would start from 0x200 (as there is no '.data'
content).
However, right now, the LMA for '.data.1' would be 0x101, following on
from the '.text' section, this is because the change in LMA for the
'.data' section is not noticed by the linker, if there's no content in
the '.data' section.
What can be even more confusing to a user (though the cause is obvious
once you understand what's going on) is that adding some content to
'.data' will cause the orphan '.data.1' to switch to an LMA based off of
0x200.
This commit changes the behaviour so that an empty section that is in
the default lma region, and sets its lma, will adjust the lma of the
default region, this change will then be reflected in following sections
within the default lma memory region.
There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features. For now I've set the test to ignore these targets.

ld: better handling of lma region for orphan sections
When picking an lma_region for an orphan section we currently create a
new lang_output_section_statement_type and then populate this with the
orphan section.
The problem is that the lang_output_section_statement_type has a prev
pointer that links back to the previous output section. For non-orphan
output sections, that are created in linker script order, the prev
pointer will point to the output section that appears previous in linker
script order, as you'd probably expect.
The problem is that orphan sections are placed after processing the
linker script, and so, in the case of an output section created for an
orphan input section, the prev pointer actually points to the last
output section created.
This causes some unexpected behaviour when the orphan section is not
placed after the last non-orphan section that was created.
For example, consider this linker script:
MEMORY {
TEXT : ORIGIN = 0x200, LENGTH = 0x10
RODATA : ORIGIN = 0x400, LENGTH = 0x10
}
SECTIONS {
.text : {*(.text) } AT>TEXT
.data : AT(0x300) { *(.data) }
.rodata : { *(.rodata) } AT>RODATA
}
If we are processing an orphan section '.data.1' and decide to place
this after '.data', then the output section created will have a prev
pointer that references the '.rodata' output section. The result of
this is that '.data.1' will actually be assigned to the RODATA lma
region, which is probably not the expected behaviour.
The reason why '.data.1' is placed into the lma region of the '.rodata'
section is that lma region propagation is done at the time we create the
output section, based on the previous output section pointer, which is
really just a last-output-section-created pointer at that point in time,
though the prev point is fixed up later to reflect the true order of the
output sections.
The solution I propose in this commit is to move the propagation of lma
regions into a separate pass of the linker, rather than performing this
as part of the enter/exit of output sections during linker script
parsing.
During this later phase we have all of the output sections to hand, and
the prev/next points have been fixed up by this point to reflect the
actual placement ordering.
There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features. For now I've set the test to ignore these targets.

X86: Add pseudo prefixes to control encoding
Many x86 instructions have more than one encodings. Assembler picks
the default one, usually the shortest one. Although the ".s", ".d8"
and ".d32" suffixes can be used to swap register operands or specify
displacement size, they aren't very flexible. This patch adds pseudo
prefixes, {xxx}, to control instruction encoding. The available
pseudo prefixes are {disp8}, {disp32}, {load}, {store}, {vex2}, {vex3}
and {evex}. Pseudo prefixes are preferred over the ".s", ".d8" and
".d32" suffixes, which are deprecated.

Fix PR18360 - internal error when using "interrupt -a"
If you do "interrupt -a" just while some thread is stepping over a
breakpoint, gdb trips on an internal error.
The test added by this patch manages to trigger this consistently by
spawning a few threads that are constantly tripping on a conditional
breakpoint whose condition always evaluates to false. With current
gdb, you get:
~~~
interrupt -a
.../src/gdb/inline-frame.c:343: internal-error: void skip_inline_frames(ptid_t): Assertion `find_inline_frame_state (ptid) == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/interrupt-while-step-over.exp: displaced-stepping=on: iter=0: interrupt -a (GDB internal error)
[...]
.../src/gdb/inline-frame.c:343: internal-error: void skip_inline_frames(ptid_t): Assertion `find_inline_frame_state (ptid) == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/interrupt-while-step-over.exp: displaced-stepping=off: iter=0: wait for stops (GDB internal error)
~~~
The assertion triggers because we're processing a stop for a thread
that had already stopped before and thus had already its inline-frame
state filled in.
Calling handle_inferior_event_1 directly within a
"thread_stop_requested" observer is something that I've wanted to get
rid of before, for being fragile. Nowadays, infrun is aware of
threads with pending events, so we can use that instead, and let the
normal fetch_inferior_event -> handle_inferior_event code path handle
the forced stop.
The change to finish_step_over is necessary because sometimes a thread
that was told to PTRACE_SINGLESTEP reports back a SIGSTOP instead of a
SIGTRAP (i.e., we tell it to single-step, and then interrupt it quick
enough that on the kernel side the thread dequeues the SIGTOP before
ever having had a chance of executing the instruction to be stepped).
SIGSTOP gets translated to a GDB_SIGNAL_0. And then finish_step_over
would miss calling clear_step_over_info, and thus miss restarting the
other threads (which in this case of threads with pending events,
means setting their "resumed" flag, so their pending events can be
consumed).
And now that we always restart threads in finish_step_over, we no
longer need to do that in handle_signal_stop.
Tested on x86_64 Fedora 23, native and gdbserver.

Fix PR 21218: GDB dumps core when escaping newline in multi-line command
With commit 3b12939dfc2399 ("Replace the sync_execution global with a
new enum prompt_state tristate"), GDB started aborting if you try
splitting an input line with a continuation char (backslash) while in
a multi-line command:
(gdb) commands
Type commands for breakpoint(s) 1, one per line.
End with a line saying just "end".
>print \
(gdb) 1 # note "(gdb)" incorrectly printed here.
>end
readline: readline_callback_read_char() called with no handler!
$
That abort is actually a symptom of an old problem introduced when
gdb_readline_wrapper was rewritten to use asynchronous readline, back
in 2007. Note how the "(gdb)" prompt is printed above in the "(gdb)
1" line. Clearly it shouldn't be there, but it already was before the
commit mentioned above. Fixing that also fixes the readline abort
shown above.
The problem starts when command_line_input passes a NULL prompt to
gdb_readline_wrapper when it finds previous incomplete input due to a
backslash, trying to fetch more input without printing another ">"
secondary prompt. That itself should not be a problem, because
passing NULL to gdb_readline_wrapper has the same meaning as passing a
pointer to empty string, since gdb_readline_wrapper exposes the same
interface as 'readline(char *)'. However, gdb_readline_wrapper passes
the prompt argument directly to display_gdb_prompt, and for the
latter, a NULL prompt argument has a different meaning - it requests
printing the primary prompt.
Before commit 782a7b8ef9c096 (which rewrote gdb_readline_wrapper to
use asynchronous readline), GDB behaved like this:
(gdb) commands
[....]
>print \
1
>end
(gdb)
The above is what this commit restores GDB back to.
New test included.

Fix PR tui/21216: TUI line breaks regression
Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make
ui_file a class hierarchy") regressed the TUI's command window.
Newlines miss doing a "carriage return", resulting in output like:
~~~~~~~~~~~~~~~~~~
(gdb) helpList of classes of commands:
aliases -- Aliases of other commands
breakpoints -- Making program stop at certain points
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Before the commit mentioned above, the default ui_file->to_write
implementation had a hack that would defer into the ui_file->to_fputs
method. The TUI's ui_file did not implement the to_write method, so
all writes would end up going to the ncurses window via tui_file_fputs
-> tui_puts.
After the commit above, the hack is gone, but the TUI's ui_file still
does not implement the ui_file::write method. Since tui_file inherits
from stdio_file, writing to a tui_file ends up doing fwrite on the
FILE stream the TUI is "associated" with, via stdio_file::write,
instead of writing to the ncurses window.
The fix is to have tui_file override the "write" method.
New test included.

Fix "layout reg" crash
Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make

regs", that leads gdb to crash when issuing:
./gdb ./a.out -ex 'layout regs' -ex start
From the backtrace, it's caused by this 'delete' on tui_restore_gdbout():

714 delete gdb_stdout;
The problem is simply that the commit mentioned above made the ui_file
that gdb_stdout is temporarily set to be a stack-allocated
string_file, while before it used to be a heap-allocated ui_file. The
fix is simply to remove the now-incorrect delete.
New test included, which exercises enabling all TUI layouts, with and
without execution. (This particular crash only triggers with
execution.)

amd64-mpx: initialize BND register before performing inferior calls.
This patch initializes the BND registers before executing the inferior
call. BND registers can be in arbitrary values at the moment of the
inferior call. In case the function being called uses as part of the
parameters BND register, e.g. when passing a pointer as parameter, the
current value of the register will be used. This can cause boundary
violations that are not due to a real bug or even desired by the user.
In this sense the best to be done is set the BND registers to allow
access to the whole memory, i.e. initialized state, before pushing the
inferior call.

Certain insns have restrictions on fields. For example, the insn

register as its destination and that register cannot appear in
either of the base or index reg fields. This holds even when the RA0

gas: Emit name, comp_dir and producer strings in .debug_str.
Putting the name, comp_dir and producer strings in the .debug_str section
makes it possible to share them across CUs. This saves a small amount of

it easier for tools like rpm debugedit to adjust the source paths when
generating separate debuginfo files.

GAS: Fix bogus "attempt to move .org backwards" relaxation errors
Fix a commit 6afe8e98a664 ("internal error for backwards .org"),
<https://www.sourceware.org/ml/binutils/2008-06/msg00212.html>,
GAS regression that caused legitimate code to fail assembly with an
"attempt to move .org backwards" error.
For example with the `mips-linux' target we get:
$ cat org.s
.set mips16
la $2, foo
.org 0x1000
.align 2
foo:
.half 0
$ as -o org.o org.s
org.s: Assembler messages:
org.s:3: Error: attempt to move .org backwards
$
where the location pointer is obviously not moved backwards with `.org'.
The cause is positive `stretch' in relaxation due to a PC-relative ADDIU
instruction (produced from the LA macro used) getting expanded from 2 to
4 bytes as `foo' is noticed to be out of range for the short encoding.
This in turn triggers logic in `relax_segment' which concludes in the
processing of an `rs_org' frag produced that the location pointer is
moved backwards while in fact only the amount to space forward to the
location requested has shrunk, resulting in a negative growth of the
frag.
Correct the bad logic then and instead verify that the fixed part of an
`rs_org' frag has not overrun the location requested, as per the comment
already included with the error message:
/* Growth may be negative, but variable part of frag
cannot have fewer than 0 chars. That is, we can't
.org backwards. */
which accurately describes the regression scenario. Move the comment
ahead the conditional noted, for clarity.
Add generic and MIPS test cases for the `.org' pseudo-op, including the
test case discussed though not integrated with the offending commit in
particular, adjusted to work across all targets.

GDB: Add support for the new set/show disassembler-options commands.
This commit adds support to GDB so that it can modify the disassembler-options
value that is passed to the disassembler, similar to objdump's -M option.
Currently, the only supported targets are ARM, PowerPC and S/390, but
adding support for a new target(s) is not difficult.

x86: fix handling of 64-bit operand size VPCMPESTR{I,M}
Just like REX.W affects operand size of the implicit rAX/rDX inputs to
PCMPESTR{I,M}, VEX.W does for VPCMPESTR{I,M}. Allow Q or L suffixes on
the instructions.
Similarly the disassembler needs to be adjusted to no longer require
VEX.W to be zero for the instructions to be valid, and to emit proper
suffixes.
Note, however, that this doesn't address the problem of there being no
way to control (at least) {,E}VEX.W for 32- or 16-bit code. Nor does it
address the problem of the many WIG instructions not getting properly
disassembled when VEX.W=1.

Nios2 dynobj handling fixes
A number of places in elf32-nios.c created dynamic sections but didn't
set the hash table dynobj. That meant we could have duplicate dynamic
sections connected to a number of bfds, so size_dynamic_sections
didn't properly discard or allocate contents.
Also, the entire set of dynamic sections was created in check_relocs
on seeing GOT relocs, when only .got related sections are needed,
probably done to hide segfaults later in finish_dynamic_sections.
The patch fixes these issues and makes the assembler emit errors when
nios2 lacks the necessary pc-relative relocs for subtraction
expressions, rather than silently generating bad code.
eg. ld-elf/merge. I've also tidied uses of elf32_nios2_hash_table and
elf_hash_table.

PowerPC addpcis fix
This came up because I was looking at ld/tmpdir/addpcis.o and noticed
the odd addends on REL16DX_HA. They ought to both be -4. The error
crept in due REL16DX_HA howto being pc-relative (as indeed it should
be), and code at gas/write.c:1001 after this comment
/* Make it pc-relative. If the back-end code has not
selected a pc-relative reloc, cancel the adjustment
we do later on all pc-relative relocs. */
*not* cancelling the pc-relative adjustment. So I've made a dummy
non-relative split reloc so that the generic code handles this, rather
than attempting to add hacks later in md_apply_fix which would not be
very robust. Having the new internal reloc also makes it easy to
support
addpcis rx,sym@ha
as an equivalent to
addpcis rx,(sym-0f)@ha
0:
The patch also fixes overflow checking, which must test whether the
addi will overflow too since @l relocs don't have any overflow check.
Lastly, since I was poking at md_apply_fix, I arranged to have the
generic gas/write.c code emit errors for subtraction expressions where
we lack reloc support.

Don't make dynamic .data.rel.ro SEC_READONLY
I'd made this dynamic section read-only so a flag test distinguished
it from .dynbss, but like any other .data.rel.ro section it really
should be marked read-write. (It is read-only after relocation, not
before.) When using the standard linker scripts this usually doesn't
matter since the output section is among other read-write sections and
not page aligned. However, it might matter in the extraordinary case
of the dynamic section being the only .data.rel.ro section with the
output section just happening to be page aligned and a multiple of a
page in size. In that case the output section would be read-only, and
live it its own read-only PT_LOAD segment, which is incorrect.

ARC naughtiness causing assertion fail at elf-strtab.c:302
This patch fixes a number of issues in the ARC backend.
- The ARC size_dynamic_sections was trashing dynamic section contents,
in particular the .gnu.version_d contents. Those versions
definitions are therefore lost so they do not drain from the strtab,
resulting in assertion failures.
- The code attempting to set DT_TEXTREL was completely bogus.
- The ARC finish_dynamic_sections would segfault on trying to set
sh_entsize for .rela.plt if that section had been discarded.
- arc_create_dynamic_sections wouldn't have ever created dynamics
sections, which was just as well since the places it was called were
way too late to create dynamic sections. Its usefulness then
devolved down to finding just one dynamic section. All the others
packaged into a struct were unused.
- .interp wasn't set for PIEs.
* elf32-arc.c (struct dynamic_sections): Delete.
(enum dyn_section_types): Delete.
(dyn_section_names): Delete.
(arc_create_dynamic_sections): Delete.
(elf_arc_finish_dynamic_sections): Don't call the above. Don't
segfault on discarded .rela.plt section.
(elf_arc_size_dynamic_sections): Formatting. Don't call
arc_create_dynamic_sections. Don't allocate memory for sections
handled by the generic linker. Correct code finding relocs in
read-only sections. Set SEC_EXCLUDE on zero size .got,
.got.plt, and .dynbss sections. Do set .interp for pies.

readelf: Correct version flag formatting
Remove a trailing space or a leading pipe character from version flags
printed with `readelf --version-info'.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
$
which includes an unnecessary space after `BASE'; both call sites
already provide suitable separation from output that follows. Also if
only unknown flags were present, then lone `| <unknown>' would be
printed.

readelf: Fix incorrect "Version definition past end of section" message
Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.")
`readelf --version-info' regression that caused "Version definition past
end of section" to be always printed at the end, even with good section
data.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:

000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
Version definition past end of section
$
The cause is the `if (idx + ent.vd_next <= idx)' condition introduced to
ensure forward progress, which however always triggers for good version
definition section data as the last entry will have its `vd_next' value
set to 0.
Adjust the condition then, to say `if (idx + ent.vd_next < idx)' instead
and to ensure forward progress limit the number of entries processed to
the size of the version definition section, removing the problematic
message from output quoted above, while ensuring the original PR 17531
test case is still handled gracefully.
Add a suitable test case so that we have `readelf --version-info'
coverage; due to the lack of infrastructure needed to run the linker in
the `binutils' test suite and limited justification to implement it add
a new `readelf.exp' script to the `ld' test suite instead, intended to
gather any `readelf' test cases that require the linker to be run. If
ever we decide to have linker infrastructure added to the `binutils'
test suite, then the script can be moved between the test suites.

x86: also correctly support TEST opcode aliases
Opcodes F6/1 and F7/1 are aliases of F6/0 and F7/0 in all modes. This
complements commit 8b89fe14b5 ("X86: Decode opcode 0x82 as opcode 0x80
in 32-bit mode"), just that here 64-bit mode is also covered.

MIPS/BFD: Remove duplicate NewABI JALR relocation handling
Remove separate original NewABI JALR relocation handling, introduced
with commit d06471104a83 ("relax jalr $t9 [R_MIPS_JALR symbol] to bal
symbol"), <https://sourceware.org/ml/binutils/2003-03/msg00394.html>,
and only used by LD with the `--relax' option specified, and rely solely
on `mips_elf_perform_relocation' code, which has been introduced with
commit 1367d393bb74 ("On the RM9000 convert jal to bal if in range"),
<https://www.sourceware.org/ml/binutils/2004-12/msg00088.html> and since
made more complete, across all the three ABIs.
Also remove the `--relax' option, now irrelevant, from the tests added
with the former commit.

MIPS/BFD: Discard ineligible JALR relocations right away
Discard R_MIPS_JALR and R_MICROMIPS_JALR relocations associated with
jumps that cannot be converted to an equivalent branch right away in
`mips_elf_calculate_relocation' rather than letting them through to
`mips_elf_perform_relocation'. This includes cross-mode jumps which
need to flip the ISA bit or jumps to a misaligned location that cannot
be encoded with a branch, in addition to preemptible symbol references
already handled.
Cross-mode jumps are actually already rejected as the conversion is made
in `mips_elf_perform_relocation', so in this case this change only saves
some processing. Jumps to a misaligned location are however converted,
with bits causing misalignment lost, making resulting code functionally
different even if the lone effect is avoiding an address error exception
with an instruction fetch at the jump destination requested.
Add test cases suitable, also including GAS verification to confirm that
the JALR relocations explicitly requested have indeed been output in the
intermediate objects used.

S/390: Add support for new cpu architecture - arch12.
This adds support of new instructions to the S/390 specific parts.
The important feature of the new instruction set is the support of
single and extended precision floating point vector operations.
Note: arch12 is NOT the official name of the new CPU. It just
continues the series of archXX options supported as alternate names.
The archXX terminology refers to the edition number of the Principle
of Operations manual. The official CPU name will be added later while
keeping support of the arch12 for backwards compatibility.
No testsuite regressions.
Committed to mainline.

Use gdb::function_view in iterate_over_symtabs & co
I wanted to pass a lambda to iterate_over_symtabs (see following
patch), so I converted it to function_view, and then the rest is
cascaded from that.
This gets rid of a bunch of single-use callback functions and
corresponding manually managed callback capture types
(add_partial_datum, search_symbols_data, etc.) in favor of letting the
compiler generate them for us by using lambdas with a capture. In a
couple cases, it was more natural to convert the existing function
callbacks to function objects (i.e., operator(), e.g.,
decode_compound_collector).

Introduce gdb::function_view
This commit adds a new function_view type. This type holds a
non-owning reference to a callable. It is meant to be used as
callback type of functions, instead of using the C-style pair of
function pointer and 'void *data' arguments. function_view allows
passing references to stateful function objects / lambdas with
captures as callbacks efficiently, while function pointer + 'void *'
does not.
See the intro in the new function-view.h header for more.
Unit tests included, put into a new gdb/unittests/ subdir.

readelf: Restore a lost new line in version information
Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.")
`readelf --version-info' output formatting regression where a dropped
new line caused section header information from the `.gnu.version_d'
version definition section to be printed on the same line as this
section's first entry.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
Version definition past end of section
$
Add the new line then, to get:
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)
000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo

$
instead.

PR ld/20828: Move symbol version processing ahead of GC symbol sweep
Complement commit b531344c34b0 ("PR ld/20828: Reorder the symbol sweep
stage of section GC") and commit 81ff47b3a546 ("PR ld/20828: Fix linker
script symbols wrongly forced local with section GC") and move symbol
version processing ahead of the symbol sweep stage of section GC, all in
`bfd_elf_size_dynamic_sections', so that version symbols created stay in
the global scope and are not output as local symbols to the dynamic
symbol table in the presence of corresponding symbol definitions pulled
from a DSO involved in a link.
Consolidate the whole of symbol version processing into a single block
from all parts scattered across the function and rearranging the local
variables used as necessary, however leaving the setting of dynamic
entries associated with the DT_VERDEF, DT_VERDEFNUM, DT_VERNEED and
DT_VERNEEDNUM tags and the SEC_EXCLUDE flag for unused `.gnu.version'
section in the original places.
With the rearrangement of code blocks `Elf_Internal_Verneed *t' would
shadow the previous definition of `struct bfd_elf_version_tree *t', so
rename the former variable to `vn'.

GAS: Consistently fix labels at the `.end' pseudo-op
Fix a functional regression with the `.end' pseudo-op, introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, and commit
dcd410fe1544 ("GNU as 2.14 on IRIX 6: crashes with shared libs"),
<https://sourceware.org/ml/binutils/2003-07/msg00415.html>, which caused
symbol values for labels placed between the end of a function's contents
and its terminating `.end' followed by one of the alignment pseudo-ops
to be different depending on whether either `-mdebug', or `-mno-pdr', or
neither of the command-line options is in effect, be it implied or
specified.
Given debug-label-end.s as follows and the `mips-linux' target we have:
$ cat debug-label-end.s
.text
.globl foo
.globl bar
.align 4, 0
.ent foo
foo:
nop
.aent bar
bar:
.insn
.end foo
.align 4, 0
.space 16
.globl baz
.ent baz
baz:
nop
.end baz
.align 4, 0
.space 16
$ as -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
9: 00000004 0 FUNC GLOBAL DEFAULT 1 bar
$ as -mdebug -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
9: 00000010 0 FUNC GLOBAL DEFAULT 1 bar
$ as -mno-pdr -o debug-label-end.o debug-label-end.s
$ readelf -s debug-label-end.o | grep bar
8: 00000010 0 FUNC GLOBAL DEFAULT 1 bar
$
The reason is the call to `md_flush_pending_output', which in the case
of `mips*-*-*' targets expands to `mips_emit_delays', which in turn
calls `mips_no_prev_insn', which calls `mips_clear_insn_labels', which
clears the list of outstanding labels. That list is in turn consulted
in `mips_align', called in the interpretation of alignment directives,
and the labels adjusted to the current location.
A call to `md_flush_pending_output' is only made from `s_mips_end' and
then only if `-mpdr' is in effect, which is the default for `*-*-linux*'
and some other `mips*-*-*' targets. A call to `md_flush_pending_output'
is never made from `ecoff_directive_end', which is used in place of
`s_mips_end' when `-mdebug' is in effect. Consequently if `-mno-pdr' or
`-mdebug' is in effect the list of outstanding labels makes it through
to any alignment directive that follows and the labels are differently
interpreted depending on the command-lines options used. And we want
code produced to be always the same.
Call `md_flush_pending_output' unconditionally then in `s_mips_end' and
add such a call from `ecoff_directive_end' as well, as long as the macro
is defined. While `ecoff_directive_end' is shared among targets, the
only one other than `mips*-*-*' actually using it is `alpha*-*-*' and it
does not define `md_flush_pending_output'. So the semantics isn't going
to change for it and neither it has to have its `s_alpha_end' updated
or have code in `ecoff_directive_end' conditionalized.

even if right now this likely is only a latent bug.

DWARF-5: DW_FORM_data16
DWARF-5 has new form DW_FORM_data16. The problem is that GDB cannot pass
16-byte constant as a constant value as that would require GDB to use GCC
extension __int128.
Formerly such data was coded as DW_FORM_block* so GDB still decodes
DW_FORM_data16 like DW_FORM_block*.

DWARF-5 has .debug_rnglists which is somehow similar to .debug_ranges.
This patch converts dwarf2_ranges_read to dwarf2_ranges_process which can work

It also simplifies dwarf2_record_block_ranges which can benefit from it.

PR gdb/16188: Verify PTRACE_TRACEME succeeded
This patch fixes PR gdb/16188, which is about the fact that
fork_inferior doesn't verify the return value of the "traceme_fun"
callback. On most targets, this callback is actually a wrapper to a
ptrace call that does a PTRACE_TRACEME on the forked GDB process that
will eventually become the inferior.
Thanks to Pedro, this second version of the patch is simpler and more
more logical. Basically, two helper functions are added:
trace_start_error and trace_start_error_with_name. The former can be
used when there is a customized error message to be printed to the
user. The latter works like perror_with_name, so you just need to
pass the function that error'd.
Both helper functions mentioned above do basically the same thing:
print the error message to stderr and call _exit, properly terminating
the forked inferior.
Most of the patch takes care of guarding the necessary system calls
against errors on the "traceme_fun" callbacks. It is not right to
call error on these situations, so I've replaced these calls with the
proper helper function call.
Regression-tested on BuildBot.

GAS: Add ECOFF `.aent' pseudo-op support
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op
respectively as follows[1]:
"
.aent name, symno Sets an alternate entry point for the current
procedure. Use this information when you want
to generate information for the debugger. It must
appear inside an .ent/.end pair."
and[2]:
"
.aent name [,symno]
Sets an alternate entry point for the current procedure. Use this
information when you want to generate information for the debugger.
This directive must appear between a pair of .ent and .end directives.
(The optional symno is for compiler use only. It refers to a dense
number in a .T file (symbol table).)"
Copy the approach from `s_mips_ent' then and add `.aent' support to the
`.ent' pseudo-op handler shared between the ELF and ECOFF object file
format backends, by setting BSF_FUNCTION for the symbol requested.

Memory Protection Keys for Userspace (PKU aka PKEYs) feature.
Native and remote debugging are covered by this patch.
The XSAVE area is extended with a new state containing
the 32-bit wide PKRU register. The new register is added to
amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also,
respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to
X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set
it supports.

commit a1fa17ee1556b0175afb081a7b8a13710246307a
Author: Michael Sturm <michael.sturm@intel.com>
Date: Tue Mar 22 16:26:09 2016 +0100
Add target description for avx-avx512.
Add a dedicated target description for the feature combination
avx-avx512 as implemented by certain IA CPU models.
The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared
the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers
displayed as undefined on CPUs that only implemented
X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue.
This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is
replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode.

Rename target descriptions to reflect actual content of description.
To better reflect the actual feature set covered by the IA target
descriptions, the existing descriptions are renamed. Each feature of
the extended state is added to the name of a description or xstate mask
starting from AVX.
For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux,
while amd64-avx-linux remains unchanged.
Likewise, the corresponding xstate masks are changed, e.g. from
X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK.

Change xstate_bv handling to use 8 bytes of data.
The size of the state-component bitmap as specified in
Intel(R) 64 and IA-32 Architectures Software Developer's Manual,
Chapter 13.4.2 is 8 bytes.
So far, the data types used for xstate_bv_p (gdb_byte*),
clear_bv (unsigned int) and tdep->xcr0 (uint64_t) were
inconsistent. But, since the xstate components were still
fitting into a single byte, the code still worked
as expected.
However, with the addition of the PKU feature (bit 9),
using one byte for the bitmap will no longer be sufficient.
This patch changes related code to use 64 bit data types
consistently and changes read/write acces of the XSAVE
header in the xsave buffer to use the endianess-aware
functions extract_unsigned_integer and store_unsigned_integer.
This is required to make sure that eventual differences
in endianess between host and target are taken care off.

2016-04-18 Michael Sturm <michael.sturm@intel.com>
* i387-tdep.c (i387_supply_xsave): Change type
of clear_bv to ULONGEST. Replace gdb_byte *xstate_bv_p

and store_unsigned_integer to read/write its value from
the xsave buffer.
(i387_collect_xsave): Replace gdb_byte *xstate_bv_p
with ULONGEST initial_xstate_bv and use
extract_unsigned_integer/store_unsigned_integer to
read/write its value from the xsave buffer.
Change type of clear_bv to ULONGEST.

bfd: Rename Chunk and S3Forced
The direct references in objcopy kind of look like a hack to me, so
I'm calling these symbols internal too. Certainly they aren't named
and documented as a public BFD symbol today anyway.
So ... give these bfd-internal symbols with external linkage a _bfd_
prefix to avoid collisions in the global symbol namespace.
While at it, give them names that more closely match the corresponding
option name that toggles them.
Also while at it, fix a few related comment typos.

bfd: Improve lookup of file / line information for errors
When looking up file and line information (used from the linker to
report error messages) if no symbol is passed in, then use the symbol
list to look for a matching symbol.
If a matching symbol is found then use this to look up the file / line
information.
This should improve errors when looking up file / line information for
data sections. Hopefully we should find a matching data symbol, which
should, in turn (we hope) match a DW_TAG_variable in the DWARF, this
should allow us to give accurate file / line errors for data symbols.
As the hope is to find a matching DW_TAG_variable in the DWARF then we
ignore section symbols, and prefer global symbols to locals.

before trying to fine matching file and line information.

bfd/dwarf: Improve use of previously loaded dwarf information
When parsing DWARF data in order to report file/line type error messages
we perform section placement to make section addresses unique within
relocatable object files.
Currently, if we reuse previously loaded (and cached) dwarf data then we
neglect to perform section placement, the result is that the section
addresses will not be unique, and we might, incorrectly associate an
address with the wrong debug information, and so report an incorrect
file and line number.
Further we neglect to check that that bfd for which we are looking up
debug information is actually the bfd for which the previous debug
information was loaded, it is possible that we will reuse previously
loaded debug information for a different bfd.
And finally, due to following of gnu_debuglink links in one bfd to
another, the process of checking that the cached debug information is
valid requires us to track the original bfd in the cached debug
information. The original debug information here is either the bfd that
we're interested in, not the bfd we finally load the debug information
from.
bfd/ChangeLog:
* dwarf2.c (struct dwarf2_debug): Add orig_bfd member.
(_bfd_dwarf2_slurp_debug_info): If stashed debug information does
not match current bfd, then reload debug information. Record bfd
we're loading debug info for in the stash. If we have debug
informatin in the cache then perform section placement before
returning.

ld: Add additional checking for warnings/errors in testsuite
This commit adds new actions to the run_cc_link_tests mechanism in the
linker testsuite.
Previously this procedure could take a parameter containing a regular
expression that would be matched against warnings from the linker.
After this commit the warnings parameter is removed, instead, the
actions list can contain the actions 'warning', 'error',
'warning_output', or 'error_output'. The action names are chosen to
match the actions already present in the run_dump_test procedure.
These new actions allow for the current warning checking, but also allow
for checking of errors using a regular expression. More interestingly,
the *_output actions allow for the warning/error patterns to be placed
in a separate file.
The small number of tests that make use of the warning parameter have
been updated to the new mechanism. Later commits will make use of the
new features added in this commit.
ld/ChangeLog:
* testsuite/lib/ld-lib.exp (run_cc_link_tests): Add warning,
error, warning_output, and error_output actions. Remove separate
warnings parameter.
* testsuite/ld-elf/shared.exp (build_tests): Updated to use
'warning' action.

hppa -z relro again
I misunderstood the hppa alias problem. File offsets of segments need
to be such that no page is mapped twice with different permissions.

LD: vfinfo: Make clever formatters consistent WRT function name reporting
Remove an inconsistency in linker error message processing causing that
it depends on the ability to infer the name of the originating source
file whether or not the name of the offending function is repeated by
clever formatters for each issue reported within the function.
Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an
example and the `powerpc-linux' target we have:
$ as -gdwarf2 -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
vs:
$ as -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
tocopt.o: In function `_start':
(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
Similarly with the `mips-linux' target and this source:
$ cat jal-global-multi-overflow.s
.text
.set noreorder
.space 0x2000
.align 4
.globl foo
.ent foo
foo:
jal bar
nor $0, $0
jal bar
nor $0, $0
.end foo
.space 0x1ff0
.align 4
.globl bar
.ent bar
bar:
jal foo
nor $0, $0
jal foo
nor $0, $0
.end bar
$ as -o jal-global-multi-overflow.o jal-global-multi-overflow.s
$ ld -Ttext 0x1fffd000 -e foo -o jal-global-multi-overflow jal-global-multi-overflow.o
jal-global-multi-overflow.o: In function `foo':
(.text+0x2000): relocation truncated to fit: R_MIPS_26 against `bar'
jal-global-multi-overflow.o: In function `foo':
(.text+0x2008): relocation truncated to fit: R_MIPS_26 against `bar'
jal-global-multi-overflow.o: In function `bar':
(.text+0x4000): relocation truncated to fit: R_MIPS_26 against `foo'
jal-global-multi-overflow.o: In function `bar':
(.text+0x4008): relocation truncated to fit: R_MIPS_26 against `foo'
$
Not only this is inconsistent, but it causes output clutter as well with
redundant information.
The cause for this is a check in `vfinfo' the intent of which is to
print the function heading whenever (among others) the name of the
source file has changed, which however does not take into account a
situation where the name couldn't have been established both now and
previously.
Adjust the check then for this situation, yielding:
$ as -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
and:
$ as -o jal-global-multi-overflow.o jal-global-multi-overflow.s
$ ld -Ttext 0x1fffd000 -e foo -o jal-global-multi-overflow jal-global-multi-overflow.o
jal-global-multi-overflow.o: In function `foo':
(.text+0x2000): relocation truncated to fit: R_MIPS_26 against `bar'
(.text+0x2008): relocation truncated to fit: R_MIPS_26 against `bar'
jal-global-multi-overflow.o: In function `bar':
(.text+0x4000): relocation truncated to fit: R_MIPS_26 against `foo'
(.text+0x4008): relocation truncated to fit: R_MIPS_26 against `foo'
$
respectively instead. Adjust the test suite accordingly.

PowerPC/BFD: Convert `%P: %H:' to `%H:' in error messages
Remove an inconsistency in BFD linker error messages across the PowerPC
backends, where in the presence of line information the `%P: %H:' format
sequence makes the first error message produced for any given function
different from subsequent ones.
Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an
example and the `powerpc-linux' target we have:
$ as -gdwarf2 -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
ld: tocopt.o: In function `_start':
tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
ld: tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
where the first error message does not have the source file name
prefixed with the linker program executable's name, i.e. `ld:', whereas
the second error message does, as would any subsequent.
This is because with a multiple-line error message such as `%H' produces
`%P' only prints the program executable's name on the first line and not
any later ones. Also the PowerPC backend is the only part of BFD which
uses `%P' along with one of the clever `%C', `%D', `%G', `%H' format
specifiers. And last but not least this breaks a GNU Coding Standard's
requirement that error messages from compilers should look like this:
source-file-name:lineno: message
also quoted in `vfinfo' code handling these specifiers.
Convert `%P: %H:' to `%H:' in error messages across the PowerPC backends
then, yielding:
$ as -gdwarf2 -o tocopt.o -a64 tocopt.s
$ ld -o tocopt -melf64ppc tocopt.o
tocopt.o: In function `_start':
tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction.
tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction.
$
instead, making it consistent and matching the GNU Coding Standard's
requirement.

This adds an event that is emitted just before GDB presents a prompt

Big-endian targets: Fix implptrpiece.exp
The test case implptrpiece.exp accesses the second byte of the short

btrace: Use binary search to find instruction.
Currently, btrace_find_insn_by_number will iterate over all function call
segments to find the one that contains the needed instruction. This linear
search is too slow for the upcoming Python bindings that will use this
function to access instructions. This patch introduces a vector in struct
btrace_thread_info that holds pointers to all recorded function segments and
allows to use binary search.
The proper solution is to turn the underlying tree into a vector of objects
and use indices for access. This requires more work. A patch set is
currently being worked on and will be published later.

btrace: preserve call stack on function switch
On 64-bit FC25, the _dl_runtime_resolve function uses a conditional branch to
'call' a particular variant optimized for that system:
(gdb) disas _dl_runtime_resolve_avx_opt
Dump of assembler code for function _dl_runtime_resolve_avx_opt:
0x00007ffff7deeb60 <+0>: push %rax
0x00007ffff7deeb61 <+1>: push %rcx
0x00007ffff7deeb62 <+2>: push %rdx
0x00007ffff7deeb63 <+3>: mov $0x1,%ecx
0x00007ffff7deeb68 <+8>: xgetbv

0x00007ffff7deeb75 <+21>: bnd je 0x7ffff7def4a0 <_dl_runtime_resolve_sse_vex>
End of assembler dump.
When computing the function-level trace, btrace treats this as a switch from
_dl_runtime_resolve_avx_opt to _dl_runtime_resolve_sse_vex. We know that we
switched functions but we can't really say in which caller/callee relationship
those two functions are.
In addition to preserving the indentaion level, also preserve the caller
information. This is a heuristic since we don't really know. But at least in
this case, this seems to be the right thing to do.
This fixes a fail in gdb.btrace/rn-dl-bind.exp on 64-bit FC25.

Fix gdb.linespec/explicit.exp
This patch addresses timeout failures i noticed while testing aarch64-elf.
FAIL: gdb.linespec/explicit.exp: complete unique function name (timeout)
FAIL: gdb.linespec/explicit.exp: complete non-unique function name (timeout)
FAIL: gdb.linespec/explicit.exp: complete non-existant function name (timeout)
FAIL: gdb.linespec/explicit.exp: complete unique file name (timeout)
FAIL: gdb.linespec/explicit.exp: complete non-unique file name (timeout)
The timeouts were caused by an attempt to match a bell character (x07) that
doesn't show up on my particular test setup.
The bell character is output whenever one tries to complete a pattern and there
are multiple possible matches. When there is only one possible match, GDB will
complete the input pattern without outputting the bell character.
The reason for the discrepancy in this test's behavior is due to the use of
"main" for a unique name test.
On glibc-based systems, GDB may notice the "main_arena" symbol, which is
a data global part of glibc's malloc implementation. Therefore a bell character
will be output because we have a couple possible completion matches.
GDB should not be outputting such a data symbol as a possible match, but this
problem may/will be addressed in a future change and is besides the point of
this particular change.
On systems that are not based on glibc, GDB will not see any other possible
matches for completing "main", so there will be no bell characters.
The use of main is a bit fragile though, so the patch adds a new local function
with a name that has a greater chance of being unique and adjusts the test to
iuse it.
I've also added the regular expression switch (-re) to all the
gdb_test_multiple calls that were missing it. Hopefully this will reduce the
chances of someone wasting time trying to match a regular expression (a much
more common use case) when, in reality, the pattern is supposed to be matched
literally.

Make gdb.arch/i386-biarch-core.exp more robust
This test attempts to load a x86 core file no matter what target
architectures the tested GDB supports. If GDB doesn't know how to handle
a i386 target, it is very likely the core file will not be recognized.
In this case we should still attempt to load a core file to make sure GDB
doesn't crash or throws an internal error. But we should not proceed to
try to read memory unconditionally.
This patch makes the test check for proper i386 arch support in GDB and bails
out if i386 is not supported and the core file format is not recognized.
This addresses the spurious aarch64-elf failures i'm seeing for this test.

Do not send queries on secondary UIs
This is a follow-up to
https://sourceware.org/ml/gdb-patches/2017-02/msg00261.html
This patch restricts queries to the main UI, which allows to avoid two
different problems.
The first one is that GDB is issuing queries on secondary MI channels
for which a TTY is allocated. The second one is that GDB is not able to
handle queries on two (CLI) UIs simultaneously. Restricting queries to
the main UI allows to bypass these two problems.
More details on how/why these two problems happen:
1. Queries on secondary MI UI
The current criterion to decide if we should query the user is whether
the input stream is a TTY. The original way to start GDB in MI mode
from a front-end was to create a subprocess with pipes to its
stdin/stdout. In this case, the input was considered non-interactive
and queries were auto-answered. Now that front-ends can create the MI
channel as a separate UI connected to a dedicated TTY, GDB now
considers this input stream as interactive and sends queries to it.
By restricting queries to the main UI, we make sure we never query on
the secondary MI UI.
2. Simultaneous queries
As Pedro stated it, when you have two queries on two different CLI UIs
at the same time, you end up with the following pseudo stack:
#0 gdb_readline_wrapper
#1 defaulted_query // for UI #2
#2 handle_command
#3 execute_command ("handle SIGTRAP" ....
#4 stdin_event_handler // input on UI #2
#5 gdb_do_one_event
#7 gdb_readline_wrapper
#8 defaulted_query // for UI #1
#9 handle_command
#10 execute_command ("handle SIGINT" ....
#11 stdin_event_handler // input on UI #1
#12 gdb_do_one_event
#13 gdb_readline_wrapper
trying to answer the query on UI #1 will therefore answer for UI #2.
By restricting the queries to the main UI, we ensure that there will
never be more than one pending query, since you can't have two queries
on a UI at the same time.
I added a snippet to gdb.base/new-ui.exp to verify that we get a query
on the main UI, but that we don't on the secondary one (or, more
precisely, that it gets auto-answered).
gdb/ChangeLog:
* utils.c (defaulted_query): Don't query on secondary UIs.

Remove some ui_out-related cleanups from Python
This patch introduces a bit of infrastructure -- namely, a minimal
std::optional analogue called gdb::optional, and an RAII template
class that works like make_cleanup_ui_out_tuple_begin_end or
make_cleanup_ui_out_list_begin_end -- and then uses these in the
Python code. This removes a number of cleanups and generally
simplifies this code.
std::optional is only available in C++17. Normally I would have had
this code check __cplusplus, but my gcc apparently isn't new enough to
find <optional>, even with -std=c++1z; so, because I could not test
it, the patch does not do this.

Eliminate interp::quiet_p
This commit removes interp::quiet_p / interp_quiet_p /
interp_set_quiet, because AFAICS, it doesn't really do anything.
interp_quiet is only ever checked inside interp_set nowadays:
if (!first_time && !interp_quiet_p (interp))
{
xsnprintf (buffer, sizeof (buffer),
"Switching to interpreter \"%.24s\".\n", interp->name);
current_uiout->text (buffer);
}
I did a bit of archaelogy, and found that back in 4a8f6654 (2003), it
was also called in another place, to decide whether to print the CLI
prompt.
AFAICS, that condition is always false today, making that if/then
block always dead code. If we remove that code, then there are no
interp_quiet_p uses left in the tree, so we can remove it all.
There are two paths that lead to interp_set calls:
#1 - When installing the top level interpreter. In this case,
FIRST_TIME is true.
#2 - In interpreter_exec_cmd. In this case, the interpreter is always
set quiet before interp_set is called.
Grepping a gdb.log of an x86_64 GNU/Linux run for "Switching to
interpreter" (before this patch) doesn't find any hits.
I suspect the intention of this message was to support something like
a "set interpreter ..." command that would change the interpreter
permanently. But there's no such command.
Tested on x86_64 Fedora 23.

Command abbreviation in define
When defining a new macro, "command" is not recognized as an alias for
"commands":
(gdb) define breakmain
Type commands for definition of "breakmain".
End with a line saying just "end".
>break main
>command
>echo "IN MAIN\n"
>end
(gdb)
There is a special case for while-stepping, where 'ws' and 'stepping' are
recognized explicitely. Instead of adding more special cases, this change
uses cli-decode.
gdb/ChangeLog:
* cli/cli-decode.c (find_command_name_length): Make it extern.
* cli/cli-decode.h (find_command_name_length): Declare.
* cli/cli-script.c (command_name_equals, line_first_arg):

(build_command_line): Make args a constant pointer.

Command names: make them case sensitive
Case-insensitive search for command names is an obscure undocumented
feature, which seems to be unused, is not tested and not quite
consistent. Remove it.

* cli-decode.c (lookup_cmd_1, lookup_cmd_composition):
Remove case-insensitive search.

bfd: Fix objdump --dynamic-reloc for SPARC 64-bit to show symbol names.
Fixes ld/testsuite/ld-elf/shared.exp "Build libpr16496b.so".
The root cause is in bfd/elf64-sparc.c, elf64_sparc_slurp_one_reloc_table(),
bfd_get_symcount() was used for dynamic mode as well. The fix is to use
bfd_get_dynamic_symcount().
This has been tested with sparc64-linux-gnu, and it does not introduce any
regressions.

Fix ptype of single-member Rust enums
While looking into PR rust/21097, I found that ptype of a
single-element enum in Rust did not always format the result properly.
In particular, it would leave out the members of a tuple struct.
Further testing showed that it also did the wrong thing for ordinary
struct members as well.
This patch fixes these problems. I'm marking it as being associated
with the PR, since that is where the discovery was made; but this
doesn't actually fix that PR (which I think ultimately is due to a
Rust compiler bug).
Built and regtested on x86-64 Fedora 25, using the system Rust
compiler. I'm checking this in.

C++-fy struct interp/cli_interp/tui_interp/mi_interp
- The interp->data field disappears, since we can put data in the
interpreter directly now. The "init" method remains in place, but
it now returns void.
- A few places check if the interpreter method is NULL before calling
it, and also check whether the method returns true/false. For some
of those methods, all current implementations always return true.
In those cases, this commit makes the C++-fied method return void
instead and cleans up the callers.
Tested on x86_64 Fedora 23.

only initialized after the base constructor is called. Since the
gdb_disassembler_test object is created on the stack, "verbose" has
garbage at that point. If the gargage is non-zero, then we end up
with the gdb_disassembler_test's stream incorrectly pointing to
gdb_stdout.

: gdb_disassembler (gdbarch,
(verbose ? gdb_stdout : &null_stream),
gdb_disassembler_test::read_memory),
specifically in this line:
(verbose ? gdb_stdout : &null_stream),
"verbose" has not been initialized yet, because the order of
initialization is base classes first, then members. I.e. "verbose" is
only initialized after the base constructor is called. Since the
gdb_disassembler_test object is created on the stack, "verbose" has
garbage at that point. If the gargage is non-zero, then we end up
with the gdb_disassembler_test's stream incorrectly pointing to
gdb_stdout.

MIPS/BFD: Respect the ELF gABI dynamic symbol table sort requirement
Ensure all local symbols precede external symbols in the dynamic symbol
table.
No local symbols are expected to make it to the dynamic symbol table
except for section symbols already taken care of, so this is really a
safeguard only against a potential BFD bug otherwise not so harmful,
which may become a grave one due to a symbol table sorting requirement
violation (see PR ld/20828 for an example). This means however that no
test suite coverage is possible for this change as code introduced here
is not normally expected to trigger.
Logically split then the part of the dynamic symbol table which is not
global offset table mapped, into a local area at the beginning and an
external area following. By the time `mips_elf_sort_hash_table' is
called we have the number of local dynamic symbol table entries (section
and non-section) already counted in `local_dynsymcount', so use it to
offset the external area from the beginning.

`max_local_dynindx'.
(mips_elf_sort_hash_table): Handle it.
(mips_elf_sort_hash_table_f) <GGA_NONE>: For forced local

Move "tee" building down to interpreter::set_logging_proc
This patch gets rid of this hack in mi_set_logging:
/* The tee created already is based on gdb_stdout, which for MI
is a console and so we end up in an infinite loop of console
writing to ui_file writing to console etc. So discard the
existing tee (it hasn't been used yet, and MI won't ever use
it), and create one based on raw_stdout instead. */
By pushing down responsibility for the tee creation to the
interpreter. I.e., pushing the CLI bits out of handle_redirections
down to the CLI interpreter's set_logging_proc method.
This fixes a few leaks that I spotted, and then confirmed with
"valgrind --leak-check=full":

One is fixed by transfering ownership of the log file to the tee. In
pseudo-patch, since the code was moved at the same time:
- out = new tee_file (curr_output, false, logfile.get (), false);
+ out = new tee_file (curr_output, false, logfile.get (), true);
The other is this bit in mi_set_logging:
else
{
+ delete mi->raw_stdout;
I tried to split the leak fixes to a smaller preparatory patch, but
that was difficult exactly because of the tee hack in
handle_redirections -> mi_set_logging.

Fix "-gdb-set logging redirect on" crash
This commit fixes a "-gdb-set logging redirect on" crash by not
handling "logging redirect on" on the fly.
Previous discussion here:
https://sourceware.org/ml/gdb-patches/2017-01/msg00467.html
Code for handling "logging redirect on" on the fly was added here:
https://sourceware.org/ml/gdb-patches/2010-08/msg00202.html
Meanwhile, MI gained support for logging, but flipping redirect "on"
on the fly was not considered. The result is that this sequence of
commands crashes GDB:
-gdb-set logging on
-gdb-set logging redirect on
Program received signal SIGSEGV, Segmentation fault.

The handling of redirect on the fly is not really a use case we need
to handle, IMO. Its inconsistent (other "set logging foo" commands
aren't handled on the fly), and complicates the code significantly.
Instead of complicating it further for MI, go back to the original
idea of warning, only:

Reuse buffers across gdb_pretty_print_insn calls
gdb_pretty_print_insn allocates and destroys a couple local buffers
each time it is called, which can be many times when disassembling a

holds the buffers and making gdb_pretty_print_insn a method of that
class, so that the buffers can be reused across calls.

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.
- mem_fileopen -> string_file
mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack. This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)
string_file's internal buffer is a std::string, thus the "string" in
the name. This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.
- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone
The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer. This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside. With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.
Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.
With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.
- New ui_file::printf, ui_file::puts, etc. methods
These simplify / clarify client code. I considered splitting
client-code changes, like these, e.g.:
- stb = mem_fileopen ();
- fprintf_unfiltered (stb, "%s%s%s",
- _("The valid values are:\n"),
- regdesc,
- _("The default is \"std\"."));
+ string_file stb;
+ stb.printf ("%s%s%s",
+ _("The valid values are:\n"),
+ regdesc,
+ _("The default is \"std\"."));
In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc.. I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".
- gdb_fopen replaced with stack-based objects
This avoids the need for cleanups or unique_ptr's. I.e., this:
struct ui_file *file = gdb_fopen (filename, "w");
if (filename == NULL)
perror_with_name (filename);
cleanups = make_cleanup_ui_file_delete (file);
// use file.
do_cleanups (cleanups);
is replaced with this:
stdio_file file;
if (!file.open (filename, "w"))
perror_with_name (filename);
// use file.
- odd contorsions in null_file_write / null_file_fputs around when to
call to_fputs / to_write eliminated.
- Global null_stream object
A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.
- TUI's tui_sfileopen eliminated. TUI's ui_file much simplified
The TUI's ui_file was serving a dual purpose. It supported being used
as string buffer, and supported being backed by a stdio FILE. The
string buffer part is gone, replaced by using of string_file. The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

Add back gdb_pretty_print_insn
ui_file_rewind is a ui_file method that only really works with mem
buffer files, and is a nop on other ui_file types. It'd be desirable
to eliminate it from the base ui_file interface, and move it to the
"mem_fileopen" subclass of ui_file instead. A following patch does
just that.
Unfortunately, there are a couple references to ui_file_rewind inside
gdb_disassembler::pretty_print_insn that were made harder to eliminate
with the recent addition of the gdb_disassembler wrapper.
Before the gdb_disassembler wrapper was added, in commit
e47ad6c0bd7aa3 ("Refactor disassembly code"), gdb_pretty_print_insn
used to be passed a ui_file pointer as argument, and it was simple to
adjust that pointer be a "mem_fileopen" ui_file pointer instead, since
there's only one gdb_pretty_print_insn caller.
That commit made gdb_pretty_print_insn be a method of
gdb_disassembler, and removed the method's ui_file parameter at the
same time, replaced by referencing the gdb_disassembler's stream
instead. The trouble is that a gdb_disassembler can be instantiated
with a pointer any kind of ui_file. Casting the gdb_disassembler's
stream to a mem_fileopen ui_file inside
gdb_disassembler::pretty_print_insn in order to call the reset method
would be gross hack.
The fix here is to:
- make gdb_disassembler::pretty_print_insn a be free function again
instead of a method of gdb_disassembler. I.e., bring back
gdb_pretty_print_insn.
- but, don't add back the ui_file * parameter. Instead, move the
mem_fileopen allocation inside. That is a better interface, given
that the ui_file is only ever used as temporary scratch buffer as
an implementation detail of gdb_pretty_print_insn. The function's
real "where to send output" parameter is the ui_out pointer. (A
following patch will add back buffer reuse across invocations
differently).
- don't add back a disassemble_info pointer either. That used to be
necessary for this bit:
err = m_di.read_memory_func (pc, &data, 1, &m_di);
if (err != 0)
m_di.memory_error_func (err, pc, &m_di);
... but AFAIK, it's not really necessary. We can replace those
three lines with a call to read_code. This seems to fix a
regression even, because before commit d8b49cf0c891d0 ("Don't throw
exception in dis_asm_memory_error"), that memory_error_func call
would throw an error/exception, but now it only records the error
in the gdb_disassembler's m_err_memaddr field. (read_code throws
on error.)
With all these, gdb_pretty_print_insn is completely layered on top of
gdb_disassembler only using the latter's public API.

Big-endian targets: Don't ignore offset into DW_OP_implicit_value
When a variable's location is expressed as DW_OP_implicit_value, but the
given value is longer than needed, which bytes should be used? GDB's
current logic was introduced with a patch from 2011 and uses the "least
significant" bytes:
https://sourceware.org/ml/gdb-patches/2011-08/msg00123.html
Now consider a sub-value from such a location at a given offset, accessed
through DW_OP_implicit_pointer. Which bytes should be used for that? The
patch above *always* uses the last bytes on big-endian targets, ignoring
the offset.
E.g., given the code snippet
const char foo[] = "Hello, world!";
const char *a = &foo[0];
const char *b = &foo[7];
assume that `foo' is described as DW_OP_implicit_value and `a' and `b'
each as DW_OP_implicit_pointer into that value. Then with current GDB
`*a' and `*b' yield the same result -- the string's zero terminator.
This patch basically reverts the portion of the patch above that deals
with DW_OP_implicit_value. This fixes the offset handling and also goes
back to dropping the last instead of the first bytes on big-endian targets
if the implicit value is longer than needed. The latter aspect of the
change probably doesn't matter for actual programs, but simplifies the
logic.
The patch also cleans up the original code a bit and adds appropriate test
cases.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-op-stack-value.exp: Adjust expected result of
taking a 2-byte value out of a 4-byte DWARF implicit value on
big-endian targets.
* gdb.dwarf2/nonvar-access.exp: Add more comments to existing
logic. Add test cases for DW_OP_implicit.
gdb/ChangeLog:
* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): For
DWARF_VALUE_LITERAL, no longer ignore the offset on big-endian
targets. And if the implicit value is longer than needed, extract
the first bytes instead of the "least significant" ones.

btrace: allow recording to be started (and stopped) for running threads
When recording is started for a running thread, GDB was able to start tracing
but then failed to read registers to insert the initial entry for the current
PC. We don't really need that initial entry if we don't know where exactly we
started recording. Skip that step to allow recording to be started while
threads are running.
If we do run into errors, we need to undo the tracing enable to not leak this
thread. The operation did not complete so our caller won't clean up this
thread.
For the BTRACE_FORMAT_PT btrace format, we don't need that initial entry since
it will be recorded in the trace. We can omit the call to btrace_add_pc.
gdb/
* btrace.c (btrace_enable): Do not call btrace_add_pc for
BTRACE_FORMAT_PT or if can_access_registers_ptid returns false.
(btrace_fetch): Assert can_access_registers_ptid.
* record-btrace.c (require_btrace_thread, record_btrace_info): Call
validate_registers_access.

MIPS: Add options to control branch ISA checks
Complement commit 9d862524f6ae ("MIPS: Verify the ISA mode and alignment
of branch and jump targets") and add GAS and LD options to control the
checks for invalid branches between ISA modes introduced there, to help
with some handwritten code lacking `.insn' annotation for labels used as
branch targets and code produced by older versions of GCC which suffers
from the issue with branches to code that has been optimized away,

`.insn'"), <https://gcc.gnu.org/ml/gcc-patches/2016-11/msg01061.html>.

Fix PTRACE_GETREGSET failure for compat inferiors on arm64
When running a 32-bit ARM inferior with a 32-bit ARM GDB on a 64-bit
AArch64 host, only VFP registers (NT_ARM_VFP) are available. The FPA
registers (NT_PRFPREG) are not available so GDB must not request them, as
this will fail with -EINVAL. This is most noticeably exposed when running

Change method of loading .py files in Python tests
With my debug build of Python (--with-pydebug), many tests fails because
of the same issue. Python scripts are loaded by the tests using this
pattern:
(gdb) python exec (open ('file.py').read ())
This causes Python to output this warning:
__main__:1: ResourceWarning: unclosed file <_io.TextIOWrapper name='file.py' mode='r' encoding='ANSI_X3.4-1968'>
and the test to fail because of that extra output. Instead of using the
open + read + exec trick which leaks the file and causes the warning,
why not just source the files?
(gdb) source file.py
This patch changes this, and standardizes the test names of the tests I
touched to "load python file" (some of them were empty, others were
overly complicated).

Harden tests that deal with memory regions
Exercising aarch64-elf with a custom debug stub i noticed a few failures in
both gdb.base/breakpoint-in-ro-region.exp and gdb.base/memattr.exp:
FAIL: gdb.base/breakpoint-in-ro-region.exp: create read-only mem region covering main

FAIL: gdb.base/memattr.exp: mem 2 and 4 were deleted
FAIL: gdb.base/memattr.exp: mem 2-4 were deleted
These failures don't show up with gdbserver or native gdb on Linux because
they don't export any memory maps, therefore the vector of memory regions is
empty.
Outside of that scenario, we can't guarantee the absence of memory regions
reported by the target upon a connection. In our particular target, we
provide a memory map and the memory regions vector ceases to be empty.
With a non-empty memory regions vector, manipulating memory regions will cause
gdb to be more verbose and output text. For example:
memattr.c:require_user_regions
/* Otherwise, let the user know how to get back. */
if (from_tty)
warning (_("Switching to manual control of memory regions; use "
"\"mem auto\" to fetch regions from the target again."));
memattr.c:create_mem_region
if ((lo >= n->lo && (lo < n->hi || n->hi == 0))
|| (hi > n->lo && (hi <= n->hi || n->hi == 0))
|| (lo <= n->lo && ((hi >= n->hi && n->hi != 0) || hi == 0)))
{
printf_unfiltered (_("overlapping memory region\n"));
return;
}
In my particular case i got both of the above messages.
In order to fix this, i've moved the delete_memory proc from
gdb.base/memattr.exp to a new file lib/memory.exp and made lib/gdb.exp
load that file.
For both gdb.base/breakpoint-in-ro-region.exp and gdb.base/memattr.exp the
patch clears all existing memory regions after running to main. That way we
are guaranteed to have a clean state for memory regions so the tests can
exercise whatever they want and have an expected output pattern.

Big-endian hosts: Fix "set architecture cris"
The all-architectures-1.exp test case currently yields 66 FAILs on s390x,
because the "set architecture" command fails each time when attempting to
switch to "cris", "crisv32", or "cris:common_v10_v32". Actually, the
command would succeed if the endianness had been set to "little" before.
Instead, the test case sets the endianness to "auto", which results in
"big" on s390x.
So on x86_64:
(gdb) set endian auto
The target endianness is set automatically (currently little endian)
(gdb) set architecture cris
warning: A handler for the OS ABI "AIX" is not built into this configuration
of GDB. Attempting to continue with the default cris settings.
The target architecture is assumed to be cris
But on s390x:
(gdb) set endian auto
The target endianness is set automatically (currently big endian)
(gdb) set architecture cris
Architecture `cris' not recognized.
See also the test results for s390x and ppc64be:
https://sourceware.org/ml/gdb-testers/2016-q4/msg05150.html
https://sourceware.org/ml/gdb-testers/2016-q4/msg05713.html
Indeed, cris_gdbarch_init in cris-tdep.c returns a failure unless the
user-specified endianness is "little". Other architectures usually ignore
the user-specified endianness and return a valid gdbarch anyhow, even if
they can not really cope with the given endianness.
This patch removes the check in cris-tdep.c and forces little-endian byte
order instead.
gdb/ChangeLog:
* cris-tdep.c (cris_gdbarch_init): Remove check for
info.byte_order and force it to BFD_ENDIAN_LITTLE.

Refactor gdb.reverse/insn-reverse.c
Changes in v2:
- Renamed arch-specific files to insn-reverse-<arch>.c.
- Adjusted according to reviews.
This patch prepares things for an upcoming testcase for record/replay support
on x86. As is, gdb.reverse/insn-reverse.c is divided into sections guarded by
a few #if blocks, and right now it only handles arm/aarch64.
If we move forward with requiring more tests for record/replay on different
architectures, i think this has the potential to become cluttered with a lot
of differing arch-specific code in the same file.
I've broken up the main file into other files with arch-specific bits
(insn-reverse-<arch>.c). The main file will hold the generic pieces that will
take care of calling the tests.
The arch-specific c files are then included at the top of the generic c file.
I've also added a generic initialize function since we need to run pre-test
checks on x86 to make sure the rdrand/rdseed instructions are supported,
otherwise we will run into a SIGILL.
The arch-specific files will implement their own initialize function with
whatever makes sense. Right now the aarch64 and arm files have an empty
initialization function.
Does this look reasonable?

2017-01-26 Luis Machado <lgustavo@codesourcery.com>

Fix crash when loading a core with unexpected register section size
When loading a core without an executable like so:
$ gdb --core core
for example often the gdbarch won't contain the
iterate_over_regset_sections method. For example on ARM.
This will generate a call to get_core_register_section with a NULL regset
like at corelow.c:628
get_core_register_section (regcache, NULL, ".reg", 0, 0, "general-purpose", 1);
However a check for REGSET_VARIABLE_SIZE in get_core_register_section
assumes that regset is != NULL thus leading to a crash with this backtrace:
(gdb) bt
#0 0x000000000065907b in get_core_register_section
(regcache=regcache@entry=0x2c26260, regset=regset@entry=0x0,
name=name@entry=0xdbf7b2 ".reg", min_size=min_size@entry=0,
which=which@entry=0, human_name=human_name@entry=0xdbac28
"general-purpose", required=1)
at ../../gdb/corelow.c:542
#1 0x0000000000659b70 in get_core_registers (ops=<optimized out>,
regcache=0x2c26260, regno=<optimized out>) at ../../gdb/corelow.c:628
#2 0x000000000076e5fb in target_fetch_registers
(regcache=regcache@entry=0x2c26260, regno=regno@entry=15)
at ../../gdb/target.c:3590
Note that commit: f962539ad23759 ("Warn if core file register
section is larger than expected") introduced this issue.
Thus releases > 7.8.2 are affected.
Also, this would have been caught by gdb.base/corefile.exp but the
problem is that this triggers only if the core dump is missing some data
so that it's not recognized as a linux core dump, or it's not a linux core
dump and the core file register section is larger than expected.
So if you just create a core and read it on linux with ARM the osabi is
detected properly and iterate_over_regset_sections is present and so the
problem is not triggered.
Thus creating a linux test for this with a crafted core that meets the
problem requirements is non-trivial.
This patch fixes this crash by adding a check for regset existence before
running the condition.
gdb/ChangeLog:
* corelow.c (get_core_register_section): Check for regset
existence before checking for REGSET_VARIABLE_SIZE.

Don't throw exception in dis_asm_memory_error
Hi,
GDB calls some APIs from opcodes to do disassembly and provide some
call backs. This model makes troubles on C++ exception unwinding,
because GDB is a C++ program, and opcodes is still compiled as C.
As we can see, frame #10 and #12 are C++, while #frame 11 is C,
#10 0x0000000000544228 in memory_error (err=TARGET_XFER_E_IO, memaddr=<optimized out>) at ../../binutils-gdb/gdb/corefile.c:237
#11 0x00000000006b0a54 in print_insn_aarch64 (pc=0, info=0xffffffffeeb0) at ../../binutils-gdb/opcodes/aarch64-dis.c:3185
#12 0x0000000000553590 in gdb_pretty_print_insn (gdbarch=gdbarch@entry=0xbbceb0, uiout=uiout@entry=0xbc73d0, di=di@entry=0xffffffffeeb0,
insn=0xffffffffed40, insn@entry=0xffffffffed90, flags=flags@entry=0,
C++ exception unwinder can't go across frame #11 unless it has
unwind table. However, C program on many architectures doesn't
have it in default. As a result, GDB aborts, which is described
in PR 20939.
This is not the first time we see this kind of problem. We've
had a commit 89525768cd086a0798a504c81fdf7ebcd4c904e1
"Propagate GDB/C++ exceptions across readline using sj/lj-based TRY/CATCH".
We can fix the disassembly bug in a similar way, this is the option one.
Since opcodes is built with gdb, we fix this problem in a different
way as we did for the same issue with readline. Instead of throwing
exception in dis_asm_memory_error, we record the failed memory
address, and throw exception when GDB returns from opcodes disassemblers.

Disassembly unit test: disassemble one instruction
This patch adds one unit test, which disassemble one instruction for
every gdbarch if available. The test needs one valid instruction of
each gdbarch, and most of them are got from breakpoint instruction.
For the rest gdbarch whose breakpoint instruction isn't a valid
instruction, I copy one instruction from the gas/testsuite/gas/
directory.
I get the valid instruction of most gdbarch except ia64, mep, mips,
tic6x, and xtensa. People familiar with these arch should be easy
to extend the test.
In order to achieve "do the unit test for every gdbarch", I add
selftest-arch.[c,h], so that we can register a function pointer,
which has one argument gdbarch. selftest.c will iterate over all
gdbarches to call the registered function pointer.

Refactor disassembly code
This patch addes class gdb_disassembler, and refactor
code to use it. The gdb_disassembler object is saved
in disassember_info.application_data. However,
disassember_info.application_data is already used by
gdb for arm, mips spu, and scm-disasm. In arm and mips,
.application_data is gdbarch, but we can still get gdbarch
from gdb_disassember.
The use of application_data in spu is a little bit
complicated. It creates its own disassemble_info, and
save spu_dis_asm_data in .application_data. This will
overwrite the pointer to gdb_disassembler, so we need
to find another place to save spu_dis_asm_data. I
extend disassemble_info, and put "id" there.

Use dwarf assembler in gdb.dwarf2/implptr-64bit.exp
This patch adds a DW_OP_implicit_value in dwarf assembler, and uses
dwarf assembler in implptr-64bit.exp. Using dwarf assembler in
implptr-64bit.exp exposes some limitations in dwarf assembler,
- some variables are not evaluated in the caller's context, so we
can not pass variable to assembler, like this
Dwarf::assemble $asm_file {
cu {
version $dwarf_version
addr_size $addr_size
is_64 $is_64
} {
}
and
{DW_AT_type :$struct_label "DW_FORM_ref$ref_addr_size"}
this limitation is fixed by adding "uplevel" and "subst".
- dwarf assembler doesn't emit DW_FORM_ref_addr for label referencing.
this limitation is fixed by adding a new character "%",
{ type %$int_label }
this means we want to emit DW_FORM_ref_addr for label referencing.
- we can't set the form of label referencing offset in dwarf assembler.
Nowadays, dwarf assembler guesses the form of labels, which is
DW_FORM_ref4. However, in implptr-64bit.exp, both DW_FORM_ref4
and DW_FORM_ref8 is used (see REF_ADDR in implptr-64bit.S). This
patch adds the flexibility of setting the form of label reference.
Both of them below are valid,
{DW_AT_type :$struct_label}
{DW_AT_type :$struct_label DW_FORM_ref8}
the former form is the default DW_FORM_ref4.
I compared the .debug_info of objects without and with this patch
applied. There is no changes except abbrev numbers.

Handle DW_OP_GNU_implicit_pointer in dwarf assembler
DW_OP_GNU_implicit_pointer refers to a DIE with an offset of different
sizes in different dwarf versions. In v2, the size is the pointer size,
while in v3 and above, it is the ref_addr size. This patch fixes
dwarf assembler to emit the correct size of offset. We've already fixed
this size issue in gdb,

PR ld/20828: Reorder the symbol sweep stage of section GC
Complement commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols
wrongly forced local with section GC") and move the symbol sweep stage
of section GC from `elf_gc_sweep' to `bfd_elf_size_dynamic_sections',
avoiding the need to clear the `forced_local' marker, problematic for
targets that have special processing in their `elf_backend_hide_symbol'
handler. Set `mark' instead in `bfd_elf_record_link_assignment' and,
matching changes from commit 3bd43ebcb602 ("ld --gc-sections fail with
__tls_get_addr_opt"), also in PowerPC `__tls_get_addr_opt' handling
code, removing a:
FAIL: PR ld/20828 dynamic symbols with section GC (version script)
test suite failure with the `score-elf' target.
The rationale is it is enough if symbols are swept at the beginning of
`bfd_elf_size_dynamic_sections' as it is only in this function that the
size of the GOT, the dynamic symbol table and other dynamic sections is
determined, which will depend on the number of symbols making it to the
dynamic symbol table. It is also appropriate to do the sweep at this
point as it is already after any changes have been made to symbols with
`bfd_elf_record_link_assignment', and not possible any earlier as calls
to that function are only made just beforehand -- barring audit entry
processing -- via `gld${EMULATION_NAME}_find_statement_assignment'
invoked from `gld${EMULATION_NAME}_before_allocation' which is the ELF
handler for `ldemul_before_allocation'.

PowerPC dynamic relocations
This patch fixes a number of issues with powerpc dynamic relocations.
1) Both ppc and ppc64 were emitting more dynamic symbols and
relocations than necessary, due to not supporting static linker
resolution of tls_index entries for __tls_get_addr_opt. This meant
that any @got@tlsgd or @got@tlsld reloc needed to make their symbols
dynamic and generate dptmod and dtprel relocs for the dynamic linker.
That would have been passable, but what happened was that practically
all @got relocations resulted in their symbols being made dynamic and
dynamic relocations emitted against the GOT entries. (Mostly visible
on ppc32 executables since ppc64 gcc really only uses @got style
relocs for TLS.)
2) The PowerOpen syntax was not supported with __tls_get_addr_opt.
DTPMOD/DTPREL relocs on tls_index TOC entries did not use the trick of
forcing dynamic symbols and relocations so those entries always
resulted in the full __tls_get_addr processing. gcc doesn't use the
PowerOpen syntax for TLS, and normally such code would be optimized to
TLS IE or LE so the impact of missing this support was minimal.
3) In an executable, relocations against GNU indirect functions always
used the value of their PLT stub. While this is correct, it is
better in some cases to use a dynamic relocation. An extra dynamic
relocation can mean that calls via function pointers need not bounce
through the PLT stub at runtime.
The patch also tidies the PLT handling code in ppc32
allocate_dynrelocs. Allocating PLT entries after other dynamic relocs
allows the PLT loop to omit special handling for undefined weak
symbols, and that in turn allows the loop to be simplified.

where dynamic relocs are preferable. Allow ifunc too.

tls_index entries resolvable at link time for

Fix Py_DECREF being executed without holding the GIL
When the gdbpy_ref objects get destroyed, they call Py_DECREF to
decrement the reference counter of the python object they hold a
reference to. Any time we call into the Python API, we should be
holding the GIL. The gdbpy_enter object does that for us in an
RAII-fashion.
However, if gdbpy_enter is declared after a gdbpy_ref object in a
function, gdbpy_enter's destructor will be called (and the GIL will be
released) before gdbpy_ref's destructor is called. Therefore, we will
end up calling Py_DECREF without holding the GIL.
This became obvious with Python 3.6, where memory management functions
have asserts to make sure that the GIL is held. This was exposed by
tests py-as-string.exp, py-function.exp and py-xmethods. For example:
(gdb) p $_as_string(enum_valid)

Fix python-interactive with Python 3.6
New in v2:
- Define PyMem_RawMalloc as PyMem_Malloc for Python < 3.4 and use
PyMem_RawMalloc in the code.
Since Python 3.4, the callback installed in PyOS_ReadlineFunctionPointer
should return a value allocated with PyMem_RawMalloc instead of
PyMem_Malloc. The reason is that PyMem_Malloc must be called with the
Python Global Interpreter Lock (GIL) held, which is not the case in the
context where this function is called. PyMem_RawMalloc was introduced
for cases like this.
In Python 3.6, it looks like they added an assert to verify that
PyMem_Malloc was not called without the GIL. The consequence is that
typing anything in the python-interactive mode of gdb crashes the
process. The same behavior was observed with the official package on
Arch Linux as well as with a manual Python build on Ubuntu 14.04.
This is what is shown with a debug build of Python 3.6 (the error with a
non-debug build is far less clear):
(gdb) pi

Make gdb.python/python.exp more robust
I noticed gdb.python/python.exp failing on aarch64-elf like so:

This particular test expects the line number for func1 to be 19, hardcoded.
In my aarch64-elf tests gdb thinks func1 is at line 20, making the test fail.
The following patch addresses this by reading the line number information from
GDB and comparing it against the python decoded symtab information.

Add command to erase all flash memory regions
Changes in v4:
- Replaced phex call with hex_string.
Changes in v3:
- Addressed comments by Pedro.
- Output of memory region size now in hex format.
- Misc formatting fixups.
- Addressed Simon's comments on formatting.
- Adjusted command text in the manual entry.
- Fixed up ChangeLog.
- Renamed flash_erase_all_command to flash_erase_command.
Changes in v2:
- Added NEWS entry.
- Fixed long lines.
- Address printing with paddress.
Years ago we contributed flash programming patches upstream. The following
patch is a leftover one that complements that functionality by adding a new
command to erase all reported flash memory blocks.
The command is most useful when we're dealing with flash-enabled targets
(mostly bare-metal) and we need to reset the board for some reason.
The wiping out of flash memory regions should help the target come up with a
known clean state from which the user can load a new image and resume
debugging. It is convenient enough to do this from the debugger, and there is
also an MI command to expose this functionality to the IDE's.

objdump: Better objdump section headers in wide mode
When displaying the section headers table using objdump (-h), the column
containing the section header name is currently fixed at 13 characters.
A section name that is longer than 13 characters will overflow the
column causing the table to become miss-aligned.
In this commit I change the behaviour so that _in wide mode_ (-w -h) the
section name column is dynamically resized to fit the longest section
name we plan to display. In wide mode the column still retains a
minimum width of 13 characters.
In non-wide more the behaviour is completely unchanged.
While I was changing the dump_headers function I have unified the two
printf lines that handled the different address widths into a single
printf, the address width is now passed into printf using the '*' field
width format character.
binutils/ChangeLog:
* objdump.c (dump_section_header): Extract max section name length
from data parameter, use this when formatting output.
(find_longest_section_name): New function.
(dump_headers): Calculate longest section name when in wide mode,
reformat to unify printing of header line.
ld/ChangeLog:
* testsuite/ld-elf/eh-frame-hdr.d: Update expected results.

The following change replaced an include of gregset.h by
an include of <sys/procfs.h>:

Date: Thu Aug 11 12:01:22 2016 +0100
Subject: Fix fallout from gdb/20413's fix
(x32: linux_ptrace_test_ret_to_nx: Cannot PTRACE_PEEKUSER)
Unfortunately, this broke gdbserver on Android, because that file
does not exist on this platform. This patch fixes the issue by
conditionalizing its include with HAVE_SYS_PROCFS_H (which we check
both in gdb/configure and gdbserver/configure).
gdb/ChangeLog:
* nat/linux-ptrace.c: Only include <sys/procfs.h> if
HAVE_SYS_PROCFS_H is defined.
Tested by rebuilding gdbserver on arm-android and GNU/Linux.

PR ld/20828: Fix linker script symbols wrongly forced local with section GC
Fix a generic ELF linker regression introduced with a chain of changes
made to unused input section garbage collection:
- commit 1a766c6843ce ("Also hide symbols without PLT nor GOT
references."),
<https://sourceware.org/ml/binutils/2011-09/msg00076.html>,
- commit 1d5316ab67e1 ("PR ld/13177: garbage collector retains zombie
references to external libraries"),
<https://sourceware.org/ml/binutils/2011-10/msg00161.html>,
- commit 6673f753c019 ("Fix PR 12772, garbage collection of dynamic
syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>,
causing the garbage collection of unused symbols present in a DSO
involved in a link to make identically named symbols ordinarily defined
(i.e. not hidden or PROVIDEd) by a linker script local, even though the
latter symbols are supposed to be global as if no DSO defined them as
well.
This is because linker script assignments are processed very late as
`lang_process' proceeds, down in the call to `ldemul_before_allocation',
which is made after the call to `lang_gc_sections' to do input section
garbage collecting. Consequently if unused, then any such DSO-defined
symbol has already been garbage-collected and internally marked local.
It would ordinarily be removed from dynamic symbol table output, however
a linker script assignment correctly replaces its original definition
with the new one and enters it into the dynamic symbol table produced as
it is supposed to be exported. The original local marking is however
retained making the symbol local in the dynamic symbol table and
therefore not available externally. This also causes a sorting problem
with the MIPS target, which does not expect non-section local dynamic
symbols to be output and produces an invalid binary.
Fix the problem then, by removing the `forced_local' marking for the
offending case and add suitable test cases. First to verify that unused
symbols ordinarily defined with linker script assignments remain
exported in the context of input section garbage collection whether or
not a DSO defining identically named symbols is present in the link.
Second that a linker version script still correctly retains or removes
such symbols as requested.

PR gas/20649: MIPS: Fix GOT16/LO16 reloc pairing with comdat sections
Correct a regression from commit 8614eeee67f9 ("Traditional MIPS
patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>,
which caused symbols in linkonce or what is these days known as comdat
sections to be treated as external for the purpose of PIC relocation
generation even if their binding remains STB_LOCAL. This in turn
disabled GOT16/LO16 relocation pairing with references to such symbols,
as no complementing LO16 relocation is expected for external GOT16
references in the o32 ABI, which ultimately leads to link errors, e.g.:
ld: comdat-reloc.o: Can't find matching LO16 reloc against `foo' for R_MIPS_GOT16 at 0x24 in section `.text.bar[bar]'
as with the LD test case included with this change.
Revert the special case for symbols in comdat sections then, making code
actually match `adjust_reloc_syms' as indicated in its explanatory
comment, and adjust calling code accordingly. Also bring back the
corresponding description of what now is `s_is_linkonce', lost with
commit 5f0fe04bc550 ("Improved MIPS16/MIPS32 code intermixing for

Remove magic numbers in m68k-dis.c:print_insn_arg
When I inspect the return values of disassmblers, I happen to see
various -1/-2/-3 magic numbers are used in m68k-dis.c. This patch
is to replace them with enum.
-1 and -2 is "clearly documented" in print_ins_arg's comments, but
-3 isn't. In fact, -3 is returned when FETCH_DATA returns false,
which means memory error (because fetch_data return 0 on memory
error). So I name enum PRINT_INSN_ARG_MEMORY_ERROR for -3.
This patch is a refactor patch, doesn't affect any functionality.

Remove dead serial_interface_lookup calls
By inspecting the serial_add_interface calls, I found that the serial
interface names that we have today are:
- hardwire
- terminal
- pipe
- tcp
- event
The calls to serial_interface_lookup with any other names are most
likely leftovers which can be removed since these serial interfaces
don't exist anymore. The commits that removed the "pc" and "parallel"
interfaces are respectively:

Return -1 on memory error in print_insn_msp430
Disassemblers in opcodes return -1 on memory error, but msp430 doesn't
follow this convention. If I change GDB not to throw exception in
disassemble_info.memory_error_func and rely on the return value of
disassembler, I'll get the following output.
(gdb) disassemble 0x0,+8
Dump of assembler code from 0x0 to 0x8:
0x00000000: .word 0xffff; ????
0x00000002: .word 0xffff; ????
0x00000004: .word 0xffff; ????
0x00000006: .word 0xffff; ????

Remove cleanups from execute_gdb_command
This replaces a cleanup in execute_gdb_command with an instance of
std::string.
Testing showed that this originally missed a cleanup that was returned
by prevent_dont_repeat. This version of the patch changes
prevent_dont_repeat to return a scoped_restore rather than a cleanup.

Use scoped_value_mark in dwarf2_evaluate_loc_desc_full
This changes dwarf2_evaluate_loc_desc_full to use scoped_value_mark.
Note that this function previously called do_cleanup using the same
cleanup multiple times. I had thought this was buggy, but re-reading
make_my_cleanup2 indicates that it is not. Nevertheless it is
surprising, and at least one of the calls (the one that is completely
removed in this patch) seems to have been done under the assumption
that it would still have some effect.

Add scoped_value_mark
This adds a scoped_value_mark class, that records the value mark in
the constructor and then calls value_free_to_mark in the destructor.
It then updates various spots in gdb to use this class, rather than a
cleanup.
It would be better overall to replace "struct value *" with a
shared_ptr, maybe eliminating the need for this class (watchpoints
would perhaps need some new mechanism as well). However, that's
difficult to do.

Introduce and use gdb::unlinker
This introduces a new class, gdb::unlinker, that unlinks a file in the
destructor. The user of this class has the option to preserve the
file instead, by calling the "keep" method.
This patch then changes the spots in gdb that use unlink in a cleanup
to use this class instead. In one spot I went ahead and removed all
the cleanups from the function.
This fixes one latent bug -- do_bfd_delete_cleanup could refer to
freed memory, by decref'ing the BFD before using its filename.

Use class to manage BFD reference counts
This introduces a new specialization of gdb::ref_ptr that can be used
to manage BFD reference counts. Then it changes most places in gdb to
use this new class, rather than explicit reference-counting or
cleanups. This patch removes make_cleanup_bfd_unref.
If you look you will see a couple of spots using "release" where a use
of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next
patch.
I think this patch fixes some latent bugs. For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.
I'm not 100% certain that the macho_symfile_read_all_oso change is
correct. The existing code here is hard for me to follow. One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.

Add gdb_ref_ptr.h
This adds a new gdb_ref_ptr.h, that implements a reference-counting
smart pointer class, where the user of the class supplies a
reference-counting policy object.
This class will be used in the next patch, which changes most explicit
BFD reference counts to use this new type. Meanwhile, this patch
changes gdbpy_ref to be a specialization of this new class.
This change required adding new nullptr_t overloads some operators in
gdb_ref_ptr.h. I suspect this was needed because some Python header
redefines NULL, but I'm not certain.

Change type of encoding argument to gdbpy_extract_lazy_string
This changes gdbpy_extract_lazy_string's "encoding" argument to be a

Change event code to use gdbpy_ref
This changes the event code in the Python layer to use
gdbpy_ref, simplifying the logic in many places.
It also changes evpy_emit_event not to steal a reference to its
argument. This is simpler to do now that gdbpy_ref is in use;
it's also a reasonable cleanup in its own right. While doing this I
realized that evpy_emit_event should not be calling gdbpy_print_stack
(all the outermost callers do this if needed), so I removed this as
well.

Introduce py-ref.h
This patch introduces class gdbpy_ref, which is a sort of smart
pointer that owns a single Python reference to a PyObject. This class
acts a bit like unique_ptr, but also a bit like shared_ptr (in that
copies do what you might expect); I considered going solely with
unique_ptr but it seemed quite strange to have a unique_ptr that
actually manages a shared resource.
Subsequent patches use this new class to simplify logic in the Python
layer.

Update help of the "frame" command
The help message of the "frame" command states that nothing is printed
if the command is executed from the command file or user-defined
command. My testing leads me to think that this is not true (at least
today).
(gdb) bt
#0 bar (n=17) at test.c:9
#1 0x00000000004006e0 in foo (v=17) at test.c:13
#2 0x00000000004006f0 in main () at test.c:21
(gdb) frame
#0 bar (n=17) at test.c:9
9 baz(n);
(gdb) define foo
Type commands for definition of "foo".
End with a line saying just "end".
>frame 1
>end
(gdb) foo
#1 0x00000000004006e0 in foo (v=17) at test.c:13
13 bar(v);
This patch simply removes that bit from the help message. I didn't find
anything corresponding to this in the documentation that needs to be
fixed.
The behavior change corresponding to this documentation change was done
in commit b00771232fab861fb31e42dfd5f6643ba1b43cc9.

[ARC] Add new linker emulation for nps
The arc700 nps variant uses some specific named sections to
facilitate its CMEM based instructions, which operate on memory
regions fixed at specific addresses.
This commit adds the arclinux_nps emulation, which is based on the
arclinux emulation. The new emulation uses the OTHER_SECTIONS
variable in the emulation parameters script to provide symbols
mapping to various locations in the CMEM space on nps.
The accompanying test ensures that all symbols are provided at the
correct address in the linker script.

[GOLD] Fix tests for powerpc64
PowerPC64 defines .TOC. rather than _GLOBAL_OFFSET_TABLE_, and
what's more, doesn't define it at all unless referenced. For ELFv1
ABI the symbol isn't normally referenced, so modify the test to accept
.TOC. as a variant of _GLOBAL_OFFSET_TABLE_ and 0 or 1 occurrences.
copy_test_relro as written doesn't need copy relocs on PowerPC64.
PowerPC64 is always PIC. So, modify copy_test_relro to test that the
existing vars are in fact read-only directly by deliberately causing a
sigsegv, and add another couple of vars that do cause copy relocs even
when PIC.
* testsuite/ver_test_8.sh: Accept .TOC. in lieu of

Fix inferior memory reading in GDBServer for arm/aarch32
Before this patch, some functions would read the inferior memory with
(*the_target)->read_memory, which returns the raw memory, rather than the
shadowed memory.
This is wrong since these functions do not expect to read a breakpoint
instruction and can lead to invalid behavior.
Use of raw memory in get_next_pcs_read_memory_unsigned_integer for example
could lead to get_next_pc returning an invalid pc.
Here's how this would happen:
In non-stop:
the user issues:
thread 1
step&
thread 2
step&
thread 3
step&
In a similar way as non-stop-fair-events.exp (threads are looping).
GDBServer:
linux_resume is called
GDBServer has pending events,
threads are not resumed and single-step breakpoint for thread 1 not installed.
linux_wait_1 is called with a pending event on thread 2 at pc A
GDBServer handles the event and calls proceed_all_lwps
This calls proceed_one_lwp and installs single-step breakpoints on all
the threads that need one.
Now since thread 1 needs to install a single-step breakpoint and is at pc B
(different than thread 2), a step-over is not initiated and get_next_pc
is called to figure out the next instruction from pc B.
However it may just be that thread 3 as a single step breakpoint at pc
B. And thus get_next_pc fails.
This situation is tested with non-stop-fair-events.exp.
In other words, single-step breakpoints are installed in proceed_one_lwp
for each thread. GDBserver proceeds two threads for resume_step, as
requested by GDB, and the thread proceeded later may see the single-step
breakpoints installed for the thread proceeded just now.
Tested on gdbserver-native/-m{thumb,arm} no regressions.

target_read_memory.
* linux-arm-low.c (get_next_pcs_read_memory_unsigned_integer): Likewise.

[D] Fix crash when debug expression enabled.
While casting works as expected with expression debugging turned off,
this seems to be an indication that the D language parser function is
doing something wrong in the building of the expression.
Without changing the grammar, using UNOP_CAST_TYPE is the right thing to
do here, as the TypeExp handler has already wrapped the type around a
pair of OP_TYPE opcodes.
gdb/ChangeLog:
* d-exp.y (CastExpression): Emit UNOP_CAST_TYPE.
gdb/testsuite/ChangeLog:
* gdb.dlang/debug-expr.exp: New file.

Fix PRU GAS for 32-bit hosts
The PRU GAS port I originally submitted does not build on 32bit hosts.
This patch fixes it by aligning md_number_to_chars's definition with
the global declaration in tc.h.

Run more ld tests when not native
Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only. Even
when a test needs to run, it's good to compile and link to exercise
the linker. So that's what this patch does. I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's
much simpler to just link with $CC.
This does mean that a cross build with cross-compiler installed but
no cross C-library will give lots of failures. If that turns out to
be too annoying, I guess we can write a tcl procedure to detect it and
not run all the extra tests.

Return 'int' rather than 'unsigned short' in avrdis_opcode
avrdis_opcode return type is unsigned short, but -1 at the end of
this function is returned. Additionally, print_insn_avr doesn't
handle when -1 (in case of memory error) is returned from
avrdis_opcode.
This patch changes avrdis_opcode returning int indicating the error,
and adds a new argument for instruction we got on success. The
opcode is 16-bit, so I change local variables type to uint16_t,
and include "bfd_stdint.h" as a result. On memory error,
print_insn_avr returns -1, which is a common convention among most
of print_insn_$ARCH functions.

link_hash_copy_indirect and symbol flags
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among
other things, modified _bfd_elf_link_hash_copy_indirect to not copy
ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt
and pointer_equality_needed when setting up an indirect non-versioned
symbol pointing to a non-default versioned symbol. I didn't notice at
the time, but the pr18720 testcase fails on hppa-linux with
"internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933
in elf32_hppa_relocate_section".
Now hppa-linux creates entries in the plt even for local functions, if
they are referenced using plabel (function pointer) relocations. So
needs_plt is set for foo when processing pr18720a.o. When the aliases
in pr28720b.o are processed, we get an indirection from foo to
foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol
that is used after that point, no plt entry is made for foo and we
bomb when relocating the plabel.
As shown by the hppa-linux scenario, needs_plt should be copied even
for non-default versioned symbols. I believe all of the others ought
to be copied too, with the exception of ref_dynamic. Not copying
ref_dynamic is right because if a shared lib references "foo" it
should not be satisfied by any non-default version "foo@FOO".

copying one flag, ref_dynamic, when versioned_hidden.

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

MIPS16: Simplify extended operand handling
Simplify extended operand handling and only specially process immediates
which require bit shuffling, using the generic operand insertion and
extraction handlers for the '<' (5-bit shift amount) operand code in
particular. Require the least significant bit of all extended operand
forms to be (artificially) set to 0 for their special processing to
trigger.

MIPS16/GAS: Clean up invalid unextended operand handling
Bail out right away when an unextended instruction encoding is required
either with the use of a `.t' suffix or by means of `.set noautoextend',
however an operand supplied requires the extended instruction form to be
used.
This is to avoid messing up with the internal state of the assembler,
even though no actual failures are known to happen as a result. Add
test cases for the situation concerned.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Remove "extended" BREAK/SDBBP handling
Remove special casing for the `6' operand code used for the embedded
trap code of the BREAK and the SDBBP instructions to support supposedly
extended forms of these instructions.
According to all versions of the MIPS16 ASE specifications these
instructions are not extensible [1][2][3][4][5][7][8][10][11], and as
from revision 2.50 of the MIPS16e ASE specifications it has been further
clarified what was previously implied, that non-extesiable instructions
when preceded with an EXTEND prefix must cause a Reserved Instruction
exception [5][6][9][10].
Therefore supposedly extended BREAK and SDBBP instructions do not serve
their purpose anymore as they do not cause a Bp and a Debug exception
respectively and supporting these forms in disassembly only causes
confusion.

Do not allow any explicitly coded EXTEND instruction to be automatically

Fix more cases of improper test names
I noticed more occurrences of improper test names. The rather mechanical,
tedious and large patch below addresses, hopefully, most of the leftover cases.
As usual, another pair of eyes is welcome to check if missed something or did
an invalid substitution.
This patch also fixes the prepare_for_testing calls to pass proper test names.

hppa-linux-gnu-ranlib: libcpp.a: File format not recognized
This stops an --enable-targets selection affecting the main target in
regards to forcing 64-bit archives. It also means mips64 and s390x
will revert to binutils-2.25 and binutils-2.26 behaviour of not
forcing 64-bit archives at least in the common case when plugins were
enabled.

[msp430] Sync tc-msp430.c with devices.csv
This patch syncs the generated data structure in tc-msp430.c with the
latest version of devices.csv released by TI.
My understanding is that the devices being removed were "invalid spins",
so can't be being used by anyone, and never will be. Current web
searches related to these devices return no relevant results.
Built and tested (no regressions) as follows:
Configured with: --target=msp430-elf --disable-gdb
Test variations:
msp430-sim/-mcpu=msp430
msp430-sim/-mcpu=msp430x
msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either
msp430-sim/-mhwmult=none
msp430-sim/-mhwmult=f5series

Fix problem where version script causes predefined hidden symbol to be defined twice.
When creating a predefined hidden symbol like _GLOBAL_OFFSET_TABLE_, gold
was incorrectly letting a version script add a version to the symbol,
resulting in two copies of the symbol, both STB_LOCAL, but one of which
was grouped in the globals part of the symbol table.

Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

Support aligning text section from odd addresses
Previously, the alignment directives were not correctly supported
in the text section when current alignment was only 1 byte (i.e.,
when the address was odd). Since there are no 1-byte instructions
in RISC-V, this patch resolves the bug by writing a zero byte to
obtain 2-byte alignment, at which point a 2-byte NOP can be used
to obtain 4-byte alignment.

Avoid creating symbol table entries for registers
Instructions like "jal t0, foo" were erroneously creating symbol table

reordering instruction alternatives so that t0 is first attempted to
be parsed as a register, rather than as a symbol.

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains
Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).
Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

Fix this by making the functions involved in setjmp/longjmp as
noexcept, so that the compiler knows it doesn't need to emit the
_Unwind_SjLj_Register / _Unwind_SjLj_Unregister calls for C++
exceptions.
Tested on x86_64 Fedora 23 with:
- GCC 5.3.1 w/ DWARF-based exceptions.
- GCC 7 built with --enable-sjlj-exceptions.

Set emacs default mode for the GDB directory to C++
Since GDB has switched to C++ but the file names are still .c emacs does
not load the proper mode when opening files in the gdb directory.
This patch fixes that by enabling c++ mode.
This patch also fixes indentation tweaks as discussed in this thread:
https://sourceware.org/ml/gdb-patches/2016-12/msg00074.html
Indent with gdb-code-style.el included and the .dir-locals.el is as such:
namespace TestNameSpace {
class test
{
public:
test test() {}
int m_a;
};
struct teststruct
{
int a;
}
}
gdb/ChangeLog:
* .dir-locals.el: Set c++ mode for the directory and set indent
properly.
* gdb-code-style.el: Set c-set-offset 'innamespace as a safe value
to be used in .dir-locals.el.

MIPS16/opcodes: Respect ISA and ASE in disassembly
Limit MIPS16 instruction disassembly according to the ISA level and ASE
set selected, as with the regular MIPS and microMIPS instruction sets.
Retain the property of `objdump -m mips:16' disassembling all MIPS16
instructions however, regardless of any ISA level recorded in the binary
examined.
To validate the disassembler use the GAS test suite for its convenience
of running tests across multiple ISAs, even though placing the tests in
the binutils test suite would be more appropriate. Adjust the single
binutils test which depends on 64-bit instruction disassembly to have
the ISA level required actually recorded in the binary examined.

MIPS16: Switch to 32-bit opcode table interpretation
Switch to 32-bit MIPS16 opcode table entry interpretation, similar to
how the microMIPS opcode table is handled, for both the `match' and
`mask' fields, removing special casing for JAL and JALX instructions and
their `a' and `i' operand codes throughout, while retaining automatic
processing of extendable opcodes in assembly and disassembly.
In assembly disallow size enforcement suffixes as appropriate: `.t' for
both 32-bit instructions and macros and `.e' for macros only, making
macro handling consistent with the microMIPS instruction set.
In disassembly fully decode EXTEND prefixes prepended to unsupported
instruction encodings (according to the ISA selection) rather than
dumping them as hexadecimal data along with the following instruction,
removing all special casing for the EXTEND prefix and making its
handling rely on its opcode table entry, except where it is considered a
part of an extendable instruction.

Re-work RISC-V gas flags: now we just support -mabi and -march
We've decided to standardize on two flags for RISC-V: "-march" sets the
target architecture (which determines which instructions can be
generated), and "-mabi" sets the target ABI. We needed to rework this
because the old flag set didn't support soft-float or single-float ABIs,
and didn't support an x32-style ABI on RISC-V.
Additionally, we've changed the behavior of the -march flag: it's now a
lot stricter and only parses things we can actually understand.
Additionally, it's now lowercase-only: the rationale is that while the
RISC-V ISA manual specifies that ISA strings are case-insensitive, in
Linux-land things are usually case-sensitive. Since this flag can be
used to determine library paths, we didn't want to bake some
case-insensitivity in there that would case trouble later.
This patch implements these two new flags and removes the old flags that
could conflict with these. There wasn't a RISC-V release before, so we
want to just support a clean flag set.

Rework RISC-V relocations
Before this commit we didn't cleanly support CFI directives because the
internal offsets used to get relaxed which broke them. This patch
significantly reworks how we handle linker relaxations:
* DWARF is now properly supported
* There is a ".option norelax" to disable relaxations, for when users
write assembly that can't be relaxed (if it's to be later patched up,
for example).
* There is an additional _RELAX relocation that specifies when previous
relocations can be relaxed.
We're in the process of documenting the RISC-V ELF ABI, which will
include documentation of our relocations
https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md
but we expect that this relocation set will remain ABI compatible in the
future (ie, it's safe to release).
Thanks to Kuan-Lin Chen for figuring out how to correctly relax the
debug info!

MIPS/opcodes: Only call `bfd_mips_elf_get_abiflags' if BFD64
Complement commit 5e7fc731f80e ("MIPS/opcodes: Also set disassembler's
ASE flags from ELF structures") and fix an `--enable-targets=all' GDB
build regression on 32-bit hosts where the MIPS target is a secondary:
../opcodes/libopcodes.a(mips-dis.o): In function `set_default_mips_dis_options':
mips-dis.c:(.text+0x906): undefined reference to `bfd_mips_elf_get_abiflags'
collect2: error: ld returned 1 exit status
make[2]: *** [gdb] Error 1
by avoiding making a call to the `bfd_mips_elf_get_abiflags' function,
which is not available, because there is no MIPS/ELF BFD included in
32-bit BFD builds. This call is only made from a conditional code block
guarded by a check against `bfd_target_elf_flavour', which is dead in
such a configuration, however cannot be optimized away by the compiler.
Also some other MIPS BFDs may be available, such as a.out, ECOFF or PE,
so the disassembler has to remain functional.

* mips-dis.c (set_default_mips_dis_options) [BFD64]: Only call

MIPS/opcodes: Also set disassembler's ASE flags from ELF structures
Respect any ASE flags recorded in ELF file structures for the purpose of
selecting instructions to be disassembled, preventing code from being
hex-dumped even though having been clearly indicated as valid at the
assembly time. Use date from the MIPS ABI flags structure if present,
and otherwise there may be an MDMX ASE flag set in the ELF file header.
For backwards compatibility only set extra flags and do not clear any,
preserving all previously set by the architecture selected to be
disassembled for.

ld: aarch64: fix TLS relaxation where TCB_SIZE is used
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for
ilp32. During relaxation, ld goes to do a replace:
bl __tls_get_addr => add R0, R0, TCB_SIZE
But actual implementation is:
bfd_putl32 (0x91004000, contents + rel->r_offset + 4);
Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32.
The possible fix for it is:
bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4);
But ilp32 also needs w-registers, so it's simpler to put proper
instruction in #if/#else condition.
There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new
tests added for ilp32 mode to test it.

Fix edge cases in orphan section placement.
There were still some cases I found where orphan section placement
was screwy -- where the script has no output section description for
either .data or .bss, a .bss orphan section ends up getting placed
before the .data section. In addition, if there is an output section
description for a data section not named .data (e.g., .rela.dyn),
the orphan .bss gets placed before it. This patch cleans that up,
by tracking the last allocated section even as we're adding orphans.
I've also improved segment layout in the absence of a PHDRS clause.
A zero-length NOBITS section will no longer force a new segment
when followed by a PROGBITS section.

RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite

Fix problems with bss handling in linker scripts.
PR 16711 noted that gold allocates file space for BSS sections when using
a linker script. I've fixed that by rewriting set_section_addresses and
set_section_list_addresses to track the file offset separate from the
current virtual address, so that BSS sections do not move the file offset.
Now, if a series of BSS sections come at the end of a segment, we do not
allocate file space; but if a script forces them into the middle of a
segment, we will still allocate file space (matching Gnu ld behavior).
I've also added a warning when that happens.
That exposed another problem where orphan .bss sections were sometimes
placed in the middle of a segment. For example, if the script mentions
the .got section, but both .data and .bss are orphans, gold would put
both .data and .bss in front of .got. I've fixed that by ensuring that
orphan BSS sections are always placed after all other allocated sections.
It also exposed a problem where the SUBALIGN property is not handled
properly. The ld manual clearly states that it should override input section
alignment, whether greater or less than the given alignment, but gold would
only increase an input section's alignment. Gold would also place the output
section based on its original alignment before the SUBALIGN property took
effect, leading to a misaligned output section (where the input section
was properly aligned in memory, but was not aligned relative to the start
of the section), in violation of the ELF/gABI spec. I've fixed that by
making sure that the SUBALIGN property overrides the internal alignment of
the input sections as well as the external alignment of the output section.
This affected the behavior of script_test_2, which was written to expect
a misaligned section.
The net effect is, I think, improved compatibility with the BFD linker.
There are still cases where orphan placement differs, but the differences
should be rarer and less important. ALIGN and SUBALIGN behavior is closer,
but still not an exact match -- I still found cases where ld would create
a misaligned output section, and where gold will properly align it.

The cause is that we want to access some builtin types in gdbarch init, but
it is not initialized yet. I fix it by creating the type when it is to be
used. We've already done this in sparc, sparc64 and m68k.

Add test that exercises all bfd architecture, osabi, endian, etc. combinations
This adds a test that exposes several problems fixed by earlier
patches:
#1 - Buffer overrun when host/target formats match, but sizes don't.
https://sourceware.org/ml/gdb-patches/2016-03/msg00125.html
#2 - Missing handling for FR-V FR300.
https://sourceware.org/ml/gdb-patches/2016-03/msg00117.html
#3 - BFD architectures with spaces in their names (v850).
https://sourceware.org/ml/binutils/2016-03/msg00108.html
#4 - The OS ABI names with spaces issue.
https://sourceware.org/ml/gdb-patches/2016-03/msg00116.html
#5 - Bogus HP/PA long double format.
https://sourceware.org/ml/gdb-patches/2016-03/msg00122.html
#6 - Cris big endian internal error.
https://sourceware.org/ml/gdb-patches/2016-03/msg00126.html
#7 - Several PowerPC bfd archs/machines not handled by gdb.
https://sourceware.org/bugzilla/show_bug.cgi?id=19797
And hopefully helps catch others in the future.
This started out as a test that simply did,
gdb -ex "print 1.0L"
to exercise #1 above.
Then to cover both 32-bit target / 64-bit host and the converse, I
thought of having the testcase print the floats twice, once with the
architecture set to "i386" and then to "i386:x86-64". This way it
wouldn't matter whether gdb was built as 32-bit or a 64-bit program.
Then I thought that other archs might have similar host/target
floatformat conversion issues as well. Instead of hardcoding some
architectures in the test file, I thought we could just iterate over
all bfd architectures and OS ABIs supported by the gdb build being
tested. This is what then exposed all the other problems listed
above...
With an --enable-targets=all, this exercises over 14 thousand
combinations. If left in a single test file, it all consistenly runs
in under a minute on my machine (An Intel i7-4810MQ @ 2.8 MHZ running
Fedora 23). Split in 8 chunks, as in this commit, it runs in around
25 seconds, with make -j8.
To avoid flooding the gdb.sum file, it avoids calling "pass" on each
tested combination/iteration. I'm explicitly not implementing that by
passing an empty message to gdb_test / gdb_test_multiple, because I
still want a FAIL to be logged in gdb.sum. So instead this puts the
internal passes in the gdb.log file, only, prefixed "IPASS:", for
internal pass. TBC, if some iteration fails, it'll still show up as
FAIL in gdb.sum. If this is an approach that takes on, I can see us
extending the common bits to support it for all testcases.

Compile gdb.perf/skip-prologue.c with and without debug info
gdb.perf/skip-prologue.exp is intended to measure the performance of
skipping prologue with prologue analysis by setting breakpoints.
However, if program is compiled with debug info, GDB is smart to
skip prologue by line table from debug info, so prologue analysis
is not exercised at all.
This patch adds a parameter COMPILE to specify compiling with
debug information, otherwise, it is compiled without debug
information.

Fix crash when disassembling invalid range on powerpc vle
I got a report of a gdb crash for vle and further investigation showed an
attempt to disassemble an invalid memory range. I tracked the crash down
to the code in get_powerpc_dialect, where we fail to make sure we have a
valid section pointer before dereferencing it.
There is no such problem for rs6000-based disassembling.

Hurd: In the CLI, use parse_thread_id instead of global_thread_id_to_ptid
Follow-up to commit 14f6890677849172a4b13779acd9089c9baa3a81.

Hurd, C++: kern_return_t vs. error_t
GNU/Hurd uses its own "typedef enum __error_t_codes error_t;"
([glibc]/sysdeps/mach/hurd/bits/errno.h), contrary to the default
"typedef int error_t;" ([glibc]/stdlib/errno.h).
The Mach/Hurd RPCs return kern_return_t values, for which, upon assigning them
to an error_t variable, GCC in C++ mode tells us "error: invalid conversion
from 'kern_return_t {aka int}' to 'error_t {aka __error_t_codes}'". Instead of
casting all these RPC return values to "error_t", just use "kern_return_t"
variables:

Assert on lval_register
This patch adds asserts where the value's lval must be lval_register.
This triggers an error in frame_register_unwind because VALUE_REGNUM
is used but value's lval is not lval_register.
This also reveals a design issue in frame_register_unwind, that is
arguments addrp and realnump are mutually exclusive, we either use
addrp (for lval_memory), or use realnump (for lval_register). This
can be done in a separate patch.

Add support for VCMLA and VCADD advanced SIMD complex number instructions.
The command line option is -march=armv8.3-a+fp16+simd for enabling all
instructions.
In arm-dis.c the formatting syntax was abused a bit to select between
0 vs 90 or 180 vs 270 or 90 vs 270 based on a bit value instead of
duplicating entries in the opcode table.

PowerPC64 dot-symbol compatibility bugfixes
Lots of fixes for the compatibility code that handles linking of
-mcall-aixdesc code (or that generated by 12 year old gcc) with
current ELFv1 ABI code.
1) A reference to a dot-symbol in an object file wasn't satisfied by a
function descriptor in later object files.
2) The as-needed code had bit-rotted; Shared libs now need a strong
reference to be counted as needed.
3) --gc-sections involving dot-symbols was broken, needing
func_desc_adjust to be run early and lots of other fixes.

Support an "unlimited" number of user-defined arguments
New in v2:
- A few adjustments / simplifications were possible now that we
require C++11:
. Use std::unique_ptr to make the user_args_stack std::vector own
its elements:
static std::vector<std::unique_ptr<user_args>> user_args_stack;
. use vector::emplace_back to construct elements directly in the
corresponding vectors.
. use std::to_string instead of adding a gdb::to_string
replacement.
- Now includes a test.
Docs/NEWS are unchanged from v1 and have already been approved.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I recently wrote a user-defined command that could benefit from
supporting an unlimited number of arguments:
http://palves.net/list-active-signal-handlers-with-gdb/
E.g., 'info signal-dispositions 1 2 3 4 5 6 7 8 9 10 11'
However, we currently only support up to 10 arguments passed to
user-defined commands ($arg0..$arg9).
I can't find a good reason for that, other than "old code with hard
coded limits". This patch removes that limit and modernizes the code
along the way:
- Makes the user_args struct a real C++ class that uses std::vector
for storage.
- Removes the "next" pointer from within user_args and uses a
std::vector to maintain a stack instead.
- Adds a new RAII-based scoped_user_args_level class to help
push/pop user args in the stack instead of using a cleanup.
gdb/ChangeLog:
2016-12-02 Pedro Alves <palves@redhat.com>
* NEWS: Mention that user commands now accept an unlimited number
of arguments.
* cli/cli-script.c: Include <vector>.

Test user-defined gdb commands and arguments stack
We're missing a test that makes sure that arguments to user-defined
commands are handled correctly when a user-defined command calls
another user-defined command / recurses.
The following patch changes that code, so add such a test first so we
can be confident won't be breaking this use case.

Fix PR 20559 - "eval" command and $arg0...$arg9/$argc substitution
It'd be handy to be able to iterate over command arguments in
user-defined commands, in order to support optional arguments
($arg0..$argN).
I thought I could make it work with "eval", but alas, it doesn't work
currently. E.g., with:
define test
set $i = 0
while $i < $argc
eval "print $arg%d", $i
set $i = $i + 1
end
end
we get:
(gdb) test 1
$1 = void
(gdb) test 1 2 3
$2 = void
$3 = void
$4 = void
(gdb)
The problem is that "eval" doesn't do user-defined command arguments
substitution after expanding its own argument. This patch fixes that,
which makes the example above work:
(gdb) test 1
$1 = 1
(gdb) test 1 2 3
$2 = 1
$3 = 2
$4 = 3
(gdb)
New test included, similar the above, but also exercises expanding
$argc.
I think this is likely to simplify many scripts out there, so I'm
adding an example to the manual and mentioning it in NEWS as well.

PR symtab/16264 - support DW_AT_main_subprogram
This patch adds support for DW_AT_main_subprogram.
This is PR symtab/16264.
DW_AT_main_subprogram is used to mark a program's entry point. GCC
can emit this, and I hope to change the Rust compiler to emit it as
well.
GDB already supports an older, pre-DWARF 4 convention adopted by
FORTRAN compilers, namely to emit DW_AT_calling_convention for the
"main" function. However, I think this support in GDB had a small
bug, in that it seems to rely on the DW_AT_name being read before
DW_AT_calling_convention. This patch fixes this as well.
Built and regtested on x86-64 Fedora 24 and the buildbot. New test
case included.

the de facto standard of naming command entry point functions

Add unit test to aarch64 prologue analyzer
We don't have an effective way to test prologue analyzer which is
highly dependent on instruction patterns in prologue generated by
compiler. GDB prologue analyzer may not handle the new sequences
generated by new compiler, or may still handle some sequences that
generated by very old compilers which are no longer used. The
former is a functionality issue, while the latter is a maintenance
issue.
The input and output of prologue analyzer is quite clear, so it
fits for unit test. The input is series of instructions, and the
output are 1) where prologue end, 2) where registers are saved.
In aarch64, they are represented in 'struct aarch64_prologue_cache'.
This patch refactors aarch64_analyze_prologue so it can read
instructions from either real target or test harness. In unit
test aarch64_analyze_prologue_test, aarch64_analyze_prologue gets
instructions we prepared in the test, as the input of prologue
analyzer. Then, we checked various fields in
'struct aarch64_prologue_cache'.

Class-ify ui_out_table
This patch makes a class out of the ui_out_table structure, the
structure responsible for managing the generation of an UI table.
To simplify the ui_out_table object, I changed it so that it can only be
used for generating a single object. Instead of clearing the header
list when starting a new table, we an ui_out_table when starting a
table and delete it when we're done. Therefore, the checks:
if (uiout->table->flag)
if (!uiout->table->flag)
are respectively replaced with
if (uiout->table != nullptr)
if (uiout->table == nullptr)
Note: I removed the check at the beginning of ui_out_begin, because
there is an equivalent check at the beginning of verify_field.
New in v2:
- use "enum class" for ui_out_table::state and update references.

Simplify ui-out level code
Now that we use a vector to store the levels, we don't have to keep a
separate level field in ui_out to keep track of the current level. We
can efficiently derive it from the vector size. That causes a little
change in the meaning of the level, as in they are now 1-based instead
of 0-based (the initial level has the "id" 1 now), but it shouldn't
change anything in the behavior.
Additionally, push_level and pop_level don't really need to return the
new level, making them return void simplifies the code a bit.
Finally, the ui_out_begin/ui_out_end callbacks in the ui_out_impl
interface don't need to be passed the level, it's never actually used.

Replace hand-made linked list of ui_out_hdr by vector and iterator
Instead of keeping pointers to first, last and current ui_out_hdr in
ui_out_table, we can use an std::vector and an iterator. Direct random
access of to vector helps make get_next_header a bit nicer by avoiding
iterating on all the headers. append_header_to_list is also a bit
simpler.
Also, using unique_ptr inside the vector allows expressing the ownership
of the ui_out_hdr objects by the ui_out_table object, and it simplifies
the destruction.
gdb/ChangeLog:
* ui-out.c (struct ui_out_hdr) <next>: Remove.
(struct ui_out_table) <header_first, header_last, header_next>: Remove.
<headers, headers_iterator>: New fields.

Fixup testcases outputting own name as a test name and standardize failed compilation messages
Changes in v3:
- Adjusted some testcases where the message "failed to compile" was not unique.
Changes in v2:
- Addressed comments from reviewers.
- Fixed spurious whitespaces.
- Changed compilation failure messages that included source/binary paths to
ones that are short and deterministic.
---
Another bit of cleanup to the testsuite. We have a number of tests that are
not honoring the rule of not outputting their own name as a test name.
I fixed up all the offenders i could find with the following regular
expression:
"(xfail|kfail|kpass|fail|pass|unsupported|untested) ([A-Za-z0-9]+|\\\$(.)*testfile(.)*)\.exp$"

Fix test names starting with uppercase output by basic functions
The following patch is based on the previous patch i sent and handles cases of
test names that start with an uppercase letter. Test names should start with
lowercase unless it starts with the name of a technology, architecture, ISA
etc.
This first patch addresses cases of test names output explicitly via xfail,
kfail, kpass, fail, pass, unsupported, untested and also names set with the
pattern "set test" and "set testname".

Fix calculation of synthetic symbol sizes (ppc64)
The attached patch fixes a problem where nm displays bogus information for
synthetic symbol sizes when --size-sort is used.
This happens because the synthetic symbols (dot symbols for ppc64) are
generated based on their non-dot symbols. The generation process doesn't copy
over the ELF-specific bits of the regular non-dot symbols.
When --size-sort is used, the code attempts to access the symbol size from
the ELF-specific bits and ends up reading gargabe, causing the size to be
displayed incorrectly.
With the patch, i can see dot and non-dot symbols having the same size with
--size-sort.
This doesn't fix the fact that we don't display size information for synthetic
symbols without --size-sort, which i may address in the future.

Use std::string in ui_out_table
Use std::string for the id field of the ui_out_table object.
I found that all users of ui_out_table_begin passed a non-NULL value to
the tblid parameter, so we don't have to worry about the NULL case. I
changed the tblid parameter to be a std::string while at it.

Use new/delete instead of malloc/free-based functions
The following patches introduce C++ vectors and strings as fields of the
various ui_out structures. We therefore need to use new/delete so that
their contructor/destructor is called. I find it simpler to change all
the allocations in a separate preliminary patch, rather than in each
individual patch.

Makefiles: Disable suffix rules and implicit rules
Since we don't use suffix rules nor implicit rules in gdb, we can
disable them. The advantage is a slightly faster make [1].
Here are some numbers about the speedup. I ran this on my trusty old
Intel Q6600, so the time numbers are probably higher than what you'd get
on any recent hardware. I ran "make" in the gdb/ directory of an
already built repository (configured with --enable-targets=all). I
recorded the time of execution (average of 5). I then ran "make -d" and
recorded the number of printed lines, which gives a rough idea of the
number of operations done.
I compared the following configurations, to see the impact of both the
empty .SUFFIXES target and the empty pattern rules, as well as running
"make -r", which can be considered the "ideal" case.
A - baseline
B - baseline + .SUFFIXES
C - baseline + pattern rules
D - baseline + .SUFFIXES + pattern rules
E - baseline + make -r
config | time (s) | "make -d"
-----------------------------
A | 5.74 | 2396643
B | 1.19 | 298469
C | 2.81 | 1266573
D | 1.13 | 245489
E | 1.01 | 163914
We can see that the empty .SUFFIXES target has a bigger impact than the
empty pattern rules, but still it doesn't hurt to disable the implicit
pattern rules as well.
There are still some mentions of implicit rules I can't get rid of in
the "make -d" output. For example, it's trying to build .c files from
.w files:
Looking for an implicit rule for '/home/simark/src/binutils-gdb/gdb/infrun.c'.
Trying pattern rule with stem 'infrun'.
Trying implicit prerequisite '/home/simark/src/binutils-gdb/gdb/infrun.w'.
and trying to build Makefile.in from a bunch of extensions:
Looking for an implicit rule for 'Makefile.in'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.o'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.c'.
Trying pattern rule with stem 'Makefile.in'.
Trying implicit prerequisite 'Makefile.in.cc'.
... many more ...
If somebody knows how to disable them, we can do it, but at this point
the returns are minimal, so it is not that important.
I verified that both in-tree and out-of-tree builds work.
[1] Switching from explicit rules to pattern rules for files in
subdirectories actually made it slower, so this is kind of a way to
redeem myself. But it the end it's faster than it was previously,
so it was all worth it. :)

PR20886, looping in ppc64_elf_size_stubs
The PR20886 binary is large enough that there are two stub sections
servicing .text (which is 88M). It so happens that between one
iteration of sizing and the next that one stub section grows while
the other shrinks. Since one section is always growing, the loop
never terminates.
This patch changes the algorithm to not update previous size on
shrinking, once we go past a certain number of iterations.

Move computed value's frame id to piece_closure
Nowadays, we set computed value's frame id, which is a misuse to me.
The computed value itself doesn't care about frame id, but function
value_computed_funcs (val)->read (or read_pieced_value) cares about
which frame the register is relative to, so 'struct piece_closure' is
a better place to fit frame id.
This patch adds a frame id in 'struct piece_closure', and use it
instead of using computed value's frame id.

gas: fix CBCOND diagnostics for invalid immediate operands.
This patch fixes two problems in the SPARC assembler:
- The diagnostic message
Error: Illegal operands: Immediate value in cbcond is out of range.
is incorrectly issued for non-CBCOND instructions that feature a
simm5 immediate field, such as MPMUL, MONTMUL, etc.
- When an invalid immediate operand is used in a CBCOND
instruction, two redundant error messages are issued to the
user, the second due to a stale fixup (this happens since
commit 85024cd8bcb93f4112470ecdbd6c10fc2aea724f).
Some diagnostic tests for the CBCOND instructions are also
included in the patch.
Tested in both sparc64-linux-gnu and sparcv9-linux-gnu targets.

Optimize byte-aligned copies in copy_bitwise()
The function copy_bitwise used for copying DWARF pieces can potentially
be invoked for large chunks of data. For instance, consider a large
struct one of whose members is currently located in a register. In this
case copy_bitwise would still copy the data bitwise in a loop, which is
much slower than necessary.
This change uses memcpy for the large part instead, if possible.

* dwarf2loc.c (copy_bitwise): Use memcpy for the middle part, if
it is byte-aligned.

Fix copy_bitwise()
When the user writes or reads a variable whose location is described
with DWARF pieces (DW_OP_piece or DW_OP_bit_piece), GDB's helper
function copy_bitwise is invoked for each piece. The implementation of
this function has a bug that may result in a corrupted copy, depending
on alignment and bit size. (Full-byte copies are not affected.)
This rewrites copy_bitwise, replacing its algorithm by a fixed version,
and adding an appropriate test case. Without the fix the new test case
fails, e.g.:
print def_t
$2 = {a = 0, b = 4177919}
(gdb) FAIL: gdb.dwarf2/nonvar-access.exp: print def_t
Written in binary, the wrong result above looks like this:
01111111011111111111111
Which means that two zero bits have sneaked into the copy of the
original all-one bit pattern. The test uses this simple all-one value
in order to avoid another GDB bug that causes the DWARF piece of a
DW_OP_stack_value to be taken from the wrong end on big-endian
architectures.
gdb/ChangeLog:
* dwarf2loc.c (extract_bits_primitive): Remove.
(extract_bits): Remove.
(copy_bitwise): Rewrite. Fixes a possible corruption that may
occur for non-byte-aligned copies.

Fix PR12616 - gdb does not implement DW_AT_data_bit_offset
The DW_AT_data_bit_offset attribute was introduced by DWARF V4 and
allows specifying the offset of a data member within its containing
entity. But although the new attribute was intended to replace
DW_AT_bit_offset for this purpose, GDB ignores it, and thus GCC still
emits DW_AT_bit_offset instead. See also
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71669.
This change fixes GDB's lack of support for DW_AT_data_bit_offset and

gdb: Use C++11 std::chrono
This patch fixes a few problems with GDB's time handling.
#1 - It avoids problems with gnulib's C++ namespace support
On MinGW, the struct timeval that should be passed to gnulib's
gettimeofday replacement is incompatible with libiberty's
timeval_sub/timeval_add. That's because gnulib also replaces "struct
timeval" with its own definition, while libiberty expects the
system's.
E.g., in code like this:
gettimeofday (&prompt_ended, NULL);
timeval_sub (&prompt_delta, &prompt_ended, &prompt_started);
timeval_add (&prompt_for_continue_wait_time,
&prompt_for_continue_wait_time, &prompt_delta);
That's currently handled in gdb by not using gnulib's gettimeofday at
all (see common/gdb_sys_time.h), but that #undef hack won't work with
if/when we enable gnulib's C++ namespace support, because that mode
adds compile time warnings for uses of ::gettimeofday, which are hard
errors with -Werror.
#2 - But there's an elephant in the room: gettimeofday is not monotonic...
We're using it to:
a) check how long functions take, for performance analysis
b) compute when in the future to fire events in the event-loop
c) print debug timestamps
But that's exactly what gettimeofday is NOT meant for. Straight from
the man page:
~~~
The time returned by gettimeofday() is affected by
discontinuous jumps in the system time (e.g., if the system
administrator manually changes the system time). If you need a
monotonically increasing clock, see clock_gettime(2).
~~~
std::chrono (part of the C++11 standard library) has a monotonic clock
exactly for such purposes (std::chrono::steady_clock). This commit
switches to use that instead of gettimeofday, fixing all the issues
mentioned above.

Normalize names of some source files
Most tdep/nat files are named:
<cpu>-<os>-tdep.c
<cpu>-<os>-nat.c
A few files do not respect this scheme. This patch renames them so that
they are consistent with the rest of the files. It builds fine with
--enable-targets=all, but that doesn't test the nat files. I can only
hope that my grep skill is good enough.

Makefiles: Flatten and sort file lists
I find the big file lists in the Makefiles a bit ugly and not very
practical. Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle. As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).
I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order. The diffs will be much clearer and merge
conflicts will be easier to resolve.
A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.
I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect. I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.
Running the patch through the buildbot found that gdb.base/default.exp
started to fail. The languages in the error message shown when typing
"set language" have changed order. We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.
New in v2:
- Change ordering style, directories go at the end.
- Cleanup gdbserver's and data-directory's Makefile as well.
- Add comments at top of Makefiles about the ordering.
- Remove wrong trailing backslahes.
- Fix test gdb.base/default.exp.
gdb/ChangeLog:
* Makefile.in: Add comment about file lists ordering.

Delete duplicate target short-cuts to dynamic sections
We'd like to have the elf_link_hash_table srelplt field rather than
some private target field used to save short-cuts to a PLT relocation
section. This save a little space but mainly is so that the generic
ELF code can access the field. Ditto for other dynamic sections.

gas,opcodes: fix hardware capabilities bumping in the sparc assembler.
When the assembler finds an instruction which is part of a higher
opcode architecture it bumps the current opcode architecture. For
example:
$ echo "mwait" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
However, when two instructions pertaining to the same opcode
architecture but associated to different SPARC hardware capabilities
are found in the input stream, and no GAS architecture is specified in
the command line, the assembler bangs:
$ echo "mwait; wr %g0,%g1,%mcdper" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
{standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr".
... and it should'nt, as WRMCDPER pertains to the same architecture
level than MWAIT.
This patch fixes this by extending the definition of sparc opcode
architectures to contain a set of hardware capabilities and making the
assembler to take these capabilities into account when updating the
set of allowed hwcaps when an architecture bump is triggered by some
instruction.
This way, hwcaps associated to architecture levels are maintained in
opcodes, while the assembler keeps the flexibiity of defining GAS
architectures including additional hwcaps (like -Asparcfmaf or the
v8plus* variants).
A test covering this failure case is included.

Create subobject value in pretty printer
Nowadays, we create a value of subobject in pretty printer with 'address'
being used,
value = value_from_contents_and_address (type, valaddr + embedded_offset,
address + embedded_offset);
set_value_component_location (value, val);
/* set_value_component_location resets the address, so we may
need to set it again. */
if (VALUE_LVAL (value) != lval_internalvar
&& VALUE_LVAL (value) != lval_internalvar_component
&& VALUE_LVAL (value) != lval_computed)
set_value_address (value, address + embedded_offset);
value_from_contents_and_address creates a value from memory, but the
value we are pretty-printing may not from memory at all.
Instead of using value_from_contents_and_address, we create a value
of subobject with the same location as object's but different offset.
We avoid using address in this way. As a result, parameter 'address'
in apply_val_pretty_printer is no longer needed, we can remove it in
next step.
We've already had the location of the 'whole' value, so it is safe
to assume we can create a value of 'component' or 'suboject' value
at the same location but with different offset.

This reverts commit b19753ce31da347605dfa903c6fd2158e2444f0d.
As it turns out, GCC (and the assembler) needs additional work in
order to support negative GOT offsets in 64-bit sparc. This is
breaking TLS Local Dynamic in position-independent code.

libiberty: demangler crash with missing :? or fold expression component.
When constructing an :? or fold expression that requires a third
expression only the first and second were explicitly checked to
not be NULL. Since the third expression is also required in these
constructs it needs to be explicitly checked and rejected when missing.
Otherwise the demangler will crash once it tries to d_print the
NULL component. Added two examples to demangle-expected of strings
that would crash before this fix.
Found by American Fuzzy Lop (afl) fuzzer.

libiberty: Fix some demangler crashes caused by reading past end of input.
In various situations the cplus_demangle () function could read past the
end of input causing crashes. Add checks in various places to not advance
the demangle string location and fail early when end of string is reached.
Add various examples of input strings to the testsuite that would crash
test-demangle before the fixes.
Found by using the American Fuzzy Lop (afl) fuzzer.
libiberty/ChangeLog:
* cplus-dem.c (demangle_signature): After 'H', template function,
no success and don't advance position if end of string reached.
(demangle_template): After 'z', template name, return zero on
premature end of string.
(gnu_special): Guard strchr against searching for zero characters.
(do_type): If member, only advance mangled string when 'F' found.
* testsuite/demangle-expected: Add examples of strings that could
crash the demangler by reading past end of input.

Makefile: Replace explicit subdir rules with pattern rules
When adding a .c file in subdirectory (e.g. mi/), the current practice
is to add an explicit rule, such as:
mi-cmd-break.o: $(srcdir)/mi/mi-cmd-break.c
$(COMPILE) $(srcdir)/mi/mi-cmd-break.c
$(POSTCOMPILE)
I find it a bit verbose and cumbersome. Since we now require GNU make,
we can change those rules with pattern rules, one for each subdirectory.
For example, the following rule works for all files under mi:
%.o: $(srcdir)/mi/%.c
$(COMPILE) $<
$(POSTCOMPILE)
Those pattern rules assume that the source and target files have the
same stem (foo.c and foo.o). In one case, common-agent.o is generated
from common/agent.c, to avoid a conflict with the agent.o in gdb/. In
this case, I kept the explicit rule, which takes precedence over the
pattern rule. We could also rename common/agent.c to
common/common-agent.c to get rid of the special case and still avoid the
clash, as it is done with common/common-regcache.c, for example.
This strategy was the least intrusive I found, as it only requires
changing the rules, not the target names.
I also considered two other solutions, which I did not like because I
would have had to change target names a bit everywhere.
- Replicate the source directory structure in the build directory,
which would generate common/agent.o from common/agent.c. However,
something was not right with the dependency tracking (the .deps
directory). It's probably not hard to fix, but I did not
investigate further.
- Name the object files after the directory they are in, so that
common/agent.c would generate common_agent.c.
GDBserver can benefit from the same treatment, but I'll do it in another
patch.
Built-tested with --enable-targets=all.
New in v2:
- Regroup pattern rules for .c -> .o compilation in a single place.
- Add comment about common-agent.o.

Makefile: Replace old suffix rules with pattern rules
As mentioned here [1], suffix rules are obsolete and have been
superseeded with pattern rules. People (myself included, before writing
this patch) are more likely to know what pattern rules are than suffix
rules.
AFAIK, .SUFFIXES targets are only used for those rules, and can be
removed as well.
New in v2:
- Replace rule in gdbserver/Makefile.in as well.

Remove code that checks for GNU/non-GNU make
Since GNU make is now required to build GDB, we can remove everything
that checks whether the current make implemention is the GNU one or
not. I simply removed the @GMAKE_TRUE@ prefixes and removed the whole
lines that were prefixed with @GMAKE_FALSE@.
I removed the code in the configure scripts that set those variables.
I also removed the following bits from the configure scripts:
AC_CHECK_PROGS(MAKE, make): GNU make already defines a MAKE variable
internally to be used when invoking Makefiles recursively. I don't see
this variable being used anywhere else (in scripts for example), so I
think it's safe for removal.
AC_PROG_MAKE_SET: This macro defines a SET_MAKE output variable, which
is meant to be used in Makefiles to define the MAKE variable when
using an implementation of make that doesn't already define it.
Since we are now requiring GNU make, we don't need it anymore.
Plus, I don't see SET_MAKE being used anywhere, so I don't think it
was actually doing anything...
gdb/ChangeLog:
* Makefile.in: Remove @GMAKE_TRUE@ prefixes and removes lines
prefixed with @GMAKE_FALSE@. Update comment related to non-GNU
make.

Document new hard requirement on GNU make
As discussed in [1], it would be benificial for the GDB project to start
requiring GNU make to build its software. It would allow using useful
GNU-specific constructs, such as pattern rules. It would also allow
removing the alternative code paths in the Makefiles (guarded by
GMAKE_TRUE/GMAKE_FALSE), simplifying the Makefile code.

gdb/ctf.c: Get rid of mkdir redefinition

The problem is the '#define mkdir ...'
Fortunately, we can just remove it, since gnulib's sys/stat.h
replacement already takes care of the Windows mkdir prototype quirk:
~~~
/* mingw's _mkdir() function has 1 argument, but we pass 2 arguments.
Additionally, it declares _mkdir (and depending on compile flags, an
alias mkdir), only in the nonstandard includes <direct.h> and <io.h>,
which are included above. */

# if !GNULIB_defined_rpl_mkdir
static int
rpl_mkdir (char const *name, mode_t mode)
{
return _mkdir (name);
}
~~~
That's sys_stat.in.h, part of the sys_stat module, which we explictly
pull in nowadays. It wasn't being pulled when this macro was added:
https://sourceware.org/ml/gdb-patches/2013-03/msg00736.html

gdb/ada-lang.c: one malloc -> unique_ptr<[]>
Switching gdb to use gnulib's C++ namespace mode reveals we're calling
malloc instead of xmalloc here:

We're unconditionaly using the result afterwards -- so it's not a case
of gracefully handling huge allocations.

new[] and unique_ptr<[]> instead, while at it.

Stash frame id of current frame before stashing frame id for previous frame
This patch ensures that the frame id for the current frame is stashed
before that of the previous frame (to the current frame).
First, it should be noted that the frame id for the current frame is
not stashed by get_current_frame(). The current frame's frame id is
lazily computed and stashed via calls to get_frame_id(). However,
it's possible for get_prev_frame() to be called without first stashing
the current frame.
The frame stash is used not only to speed up frame lookups, but
also to detect cycles. When attempting to compute the frame id
for a "previous" frame (in get_prev_frame_if_no_cycle), a cycle
is detected if the computed frame id is already in the stash.
If it should happen that a previous frame id is stashed which should
represent a cycle for the current frame, then an assertion failure
will trigger should get_frame_id() be later called to determine
the frame id for the current frame.
As of late 2016, with the "Tweak meaning of VALUE_FRAME_ID" patch in
place, this actually occurs when running the
gdb.dwarf2/dw2-dup-frame.exp test. While attempting to generate a
backtrace, the python frame filter code is invoked, leading to
frame_info_to_frame_object() (in python/py-frame.c) being called.
That function will potentially call get_prev_frame() before
get_frame_id() is called. The call to get_prev_frame() can eventually
end up in get_prev_frame_if_no_cycle() which, in turn, calls
compute_frame_id(), after which the frame id is stashed for the
previous frame.
If the frame id for the current frame is stashed, the cycle detection
code (which relies on the frame stash) in get_prev_frame_if_no_cycle()
will be triggered for a cycle starting with the current frame. If the
current frame's id is not stashed, the cycle detecting code can't
operate as designed. Instead, when get_frame_id() is called on the
current frame at some later point, the current frame's id will found
to be already in the stash, triggering an assertion failure.
Below is an in depth examination of the failure which lead to this change.
I've shortened pathnames for brevity and readability.
Here's the portion of the log file showing the failure/internal error:
(gdb) break stop_frame

Examination of the code in frame_info_to_frame_object(), which is in
python/py-frame.c, is key to understanding this problem:
if (get_prev_frame (frame) == NULL
&& get_frame_unwind_stop_reason (frame) != UNWIND_NO_REASON
&& get_next_frame (frame) != NULL)
{
frame_obj->frame_id = get_frame_id (get_next_frame (frame));
frame_obj->frame_id_is_next = 1;
}
else
{
frame_obj->frame_id = get_frame_id (frame);
frame_obj->frame_id_is_next = 0;
}
I will first note that the frame id for frame has not been computed yet. (This
was verified by placing a breakpoint on compute_frame_id().)
The call to get_prev_frame() causes the the frame id to (eventually) be
computed for the previous frame. Here's a backtrace showing how we
get there:
#0 compute_frame_id (fi=0x10e2810)
at gdb/frame.c:496
#1 0x0000000000724a67 in get_prev_frame_if_no_cycle (this_frame=0xe5a760)

#3 0x000000000072516b in get_prev_frame_always (this_frame=0xe5a760)

at gdb/frame.c:2303
#5 0x00000000004eb471 in frame_info_to_frame_object (frame=0xe5a760)
at gdb/python/py-frame.c:381
For this particular case, we end up in the else clause of the code above
which calls get_frame_id (frame). It's at this point that the frame id
for frame is computed. Again, here's a backtrace:
#0 compute_frame_id (fi=0xe5a760)
at gdb/frame.c:496
#1 0x000000000072203d in get_frame_id (fi=0xe5a760)
at gdb/frame.c:539
#2 0x00000000004eb50d in frame_info_to_frame_object (frame=0xe5a760)
at gdb/python/py-frame.c:390
The test in question, dw2-dup-frame.exp, deliberately creates a broken
(cyclic) stack. So, in this instance, the frame id for the prev
`frame' will be the same as that for `frame'. But that particular
frame id ended up in the stash during the previous frame operation.
When, just a few lines later, we compute the frame id for `frame', the
id in question is already in the stash, thus triggering the assertion
failure.
I considered two other solutions to solving this problem:
We could prevent get_prev_frame() from being called before
get_frame_id() in frame_info_to_frame_object(). (See above for the
snippet of code where this happens.) A call to get_frame_id (frame)
could be placed ahead of that code snippet above. I have tested this
approach and, while it does work, I can't be certain that
get_prev_frame() isn't called ahead of stashing the current frame
somewhere else in GDB, but in a less obvious way.
Another approach is to stash the current frame's id by calling
get_frame_id() in get_current_frame(). This approach is conceptually
simpler, but when importing a python unwinder, has the unwelcome side
effect of causing the unwinder to be called during import.
A cleaner looking fix would be to place this code after code
corresponding to the "Don't compute the frame id of the current frame
yet..." comment in get_prev_frame_if_no_cycle(). Sadly, this does not
work though; by the time we get to this point, the frame state for the
prev frame has been modified just enough to cause an internal error to
occur when attempting to compute the (current) frame id for inline
frames. (The unexpected failure count increases by roughly 130
failures.) Therefore, I decided to place it as early as possible
in get_prev_frame().
gdb/ChangeLog:
* frame.c (get_prev_frame): Stash frame id for current frame
prior to computing frame id for previous frame.

Make gdb.PendingFrame.read_register handle "user" registers.
The C function, pending_framepy_read_register(), which implements
the python interface gdb.PendingFrame.read_register does not handle
the so called "user" registers like "pc". An assertion error is
triggered due to the user registers having numbers larger than or
equal to gdbarch_num_regs(gdbarch).
With the VALUE_FRAME_ID tweak in place, the call to
get_frame_register_value() can simply be replaced by a call to
value_of_register(), which handles both real registers as well as the
user registers.

* python/py-unwind.c (pending_framepy_read_register): Use

Change meaning of VALUE_FRAME_ID; rename to VALUE_NEXT_FRAME_ID
The VALUE_FRAME_ID macro provides access to a member in struct value
that's used to hold the frame id that's used when determining a
register's value or when assigning to a register. The underlying
member has a long and obscure name. I won't refer to it here, but
will simply refer to VALUE_FRAME_ID as if it's the struct value member
instead of being a convenient macro.
At the moment, without this patch in place, VALUE_FRAME_ID is set in
value_of_register_lazy() and several other locations to hold the frame
id of the frame passed to those functions.
VALUE_FRAME_ID is used in the lval_register case of
value_fetch_lazy(). To fetch the register's value, it calls
get_frame_register_value() which, in turn, calls
frame_unwind_register_value() with frame->next.
A python based unwinder may wish to determine the value of a register
or evaluate an expression containing a register. When it does this,
value_fetch_lazy() will be called under some circumstances. It will
attempt to determine the frame id associated with the frame passed to
it. In so doing, it will end up back in the frame sniffer of the very
same python unwinder that's attempting to learn the value of a
register as part of the sniffing operation. This recursion is not
desirable.
As noted above, when value_fetch_lazy() wants to fetch a register's
value, it does so (indirectly) by unwinding from frame->next.
With this in mind, a solution suggests itself: Change VALUE_FRAME_ID
to hold the frame id associated with the next frame. Then, when it
comes time to obtain the value associated with the register, we can
simply unwind from the frame corresponding to the frame id stored in
VALUE_FRAME_ID. This neatly avoids the python unwinder recursion
problem by changing when the "next" operation occurs. Instead of the
"next" operation occuring when the register value is fetched, it
occurs earlier on when assigning a frame id to VALUE_FRAME_ID.
(Thanks to Pedro for this suggestion.)
This patch implements this idea.
It builds on the patch "Distinguish sentinel frame from null frame".
Without that work in place, it's necessary to check for null_id at
several places and then obtain the sentinel frame.
It also renames most occurences of VALUE_FRAME_ID to
VALUE_NEXT_FRAME_ID to reflect the new meaning of this field.
There are several uses of VALUE_FRAME_ID which were not changed. In
each case, the original meaning of VALUE_FRAME_ID is required to get
correct results. In all but one of these uses, either
put_frame_register_bytes() or get_frame_register_bytes() is being
called with the frame value obtained from VALUE_FRAME_ID. Both of
these functions perform some unwinding by performing a "->next"
operation on the frame passed to it. If we were to use the new
VALUE_NEXT_FRAME_ID macro, this would effectively do two "->next"
operations, which is not what we want.
The VALUE_FRAME_ID macro has been redefined in terms of
VALUE_NEXT_FRAME_ID. It simply fetches the previous frame's id,
providing this id as the value of the macro.

Distinguish sentinel frame from null frame.
This patch replaces the `current_frame' static global in frame.c with
`sentinel_frame'. It also makes the sentinel frame id unique and
different from the null frame.
By itself, there is not much point to this patch, but it makes
the code cleaner for the VALUE_FRAME_ID changes in another patch.
Since we now allow "navigation" to the sentinel frame, it removes
the necessity of adding special cases to other parts of GDB.
Note that a new function, get_next_frame_sentinel_okay, is introduced
in this patch. It will be used by the VALUE_FRAME_ID changes that
I've made.
Thanks to Pedro Alves for this suggestion.

Extend test gdb.python/py-recurse-unwind.exp
This patch modifies the unwinder (sniffer) defined in
py-recurse-unwind.py so that, depending upon the value of one of its
class variables, it will take different paths through the code,
testing different functionality.
The original test attempted to obtain the value of an undefined
symbol.
This somewhat expanded test checks to see if 'pc' can be read via
gdb.PendingFrame.read_register() and also via gdb.parse_and_eval().
gdb/testsuite/ChangeLog:
* gdb.python/py-recurse-unwind.c (main): Add loop.
* gdb.python/py-recurse-unwind.py (TestUnwinder): Add calls
to read_register() and gdb.parse_and_eval(). Make each code
call a separate case that can be individually tested.
* gdb.python/py-recurse-unwind.exp (cont_and_backtrace): New
proc. Call cont_and_backtrace for each of the code paths that
we want to test in the unwinder.

Fix PR20789 - relaxation with negative valued diff relocs
Fix issues with diff relocs that have a negative value
i.e. sym2 - sym1 where sym2 is lesser than sym1.
The assembler generates a diff reloc with symbol as start of section
and addend as sym2 offset, and encodes assembly time difference at
the reloc offset.
The existing relaxation logic adjusts addends if the relaxed insn lies
between symbol and addend. That doesn't work for diff relocs where
sym2 is less than sym1 *and* the relaxed insn happens to be between
sym2 and sym1.
Fix the problems by
1. Using signed handling of the difference value (bfd_signed_vma instead
of bfd_vma, bfd_{get,set}_signed_xxx instead of bfd_{get,set}_xxx).
2. Not assuming sym2 is bigger than sym1. It instead computes the actual
addresses and sets the lower and higher addresses as start and end
addresses respectively and then sees if insn is between start and end.
3. Creating a new function elf32_avr_adjust_reloc_if_spans_insn to
centralize reloc adjustment, and ensuring diff relocs get adjusted
correctly even if their sym + addend doesn't overlap a relaxed insn.
It also removes a redundant variable did_pad. It is never set if
did_shrink is TRUE, and the code does a early return if did_shrink is
FALSE.

gdb: update gnulib to pull in C++ namespace support fixes
I've been experimenting with making use of gnulib's C++ namespace support:
https://www.gnu.org/software/gnulib/manual/html_node/A-C_002b_002b-namespace-for-gnulib.html
That stumbled on a few gnulib issues, which I've fixed upstream:
[PATCH] Fix gnulib C++ namespace support and std::frexp
https://lists.gnu.org/archive/html/bug-gnulib/2016-11/msg00039.html
[PATCH] Fix real-floating argument functions in C++ mode

[PATCH] C++: "#define timeval rpl_timeval" -> typedef in GNULIB_NAMESPACE
https://lists.gnu.org/archive/html/bug-gnulib/2016-11/msg00058.html

Delete gdb::unique_ptr/gdb::move
Now that we require C++11 and all uses of gdb::unique_ptr and
gdb::move are gone, let's remove their definitions...
With my lazy hat on, I repurposed the header for "generally useful
unique_ptr specializations", and left gdb::unique_xmalloc_ptr in
there. Not sure whether we it'd be better move it out of the gdb
namespace or leave it be. I left it because it's less work and avoids
disrupting yet-unmerged patches that use it.

bitfield-parent-optimized-out: Fix struct definition
The "struct S" type in bitfield-parent-optimized-out.exp is declared to
have a size of 4 bytes but to hold two 4-byte members: an int-based
bitfield and a 4-byte int. Also, both members have the same
data_member_location 2, causing them to overlap and to reach 2 bytes
beyond the structure's boundary.
This is fixed by increasing the structure size to 8 and setting the
first and second member's data_member_location to 0 and 4, respectively.

btrace: read entire aux buffer
The data_head of a perf event data buffer grows indefinitely. Users are
expected to compute data_head % data_size to find the location inside the perf
event data buffer.
The aux_head of a perf event aux buffer wraps around and always stays within the
perf event aux buffer.
Well, at least that's the behaviour for BTS and PT - where BTS uses the data
buffer and PT the aux buffer.
GDB does not read beyond data_head or aux_head. This is OK for BTS but wrong
for PT. It causes only a portion of the trace to be considered by GDB. In the
extreme case, the buffer may appear (almost) empty.
Thanks to Tim Wiederhake <tim.wiederhake@intel.com> for reporting the anomaly.
Change it to read the entire aux buffer for PT. The buffer is initially zero so
any extra zeroes we read before aux_head wraps around the first time will be
ignored when searching for the first PSB packet in order to synchronize onto the
trace stream.

* nat/linux-btrace.c (perf_event_read): Allow data_head < size.

[AArch64] Add ARMv8.3 instructions which are in the NOP space
This patch adds support for a subset of the ARMv8.3 pointer authentication
instructions: XPACLRI, PACIA1716, PACIB1716, AUTIA1716, AUTIA1716, PACIAZ,
PACIASP, PACIBZ, PACISP, AUTIAZ, AUTIASP, AUTIBZ, AUTIBSP.
These are aliases to HINT #0x7, HINT #0x8, HINT #0xa, HINT #0xc, HINT #0xe,
HINT #0x18, HINT #0x19, ..., HINT #0x1f respectively.

Use unique_xmalloc_ptr in Python code
This changes some utility functions in the Python code to return
unique_xmalloc_ptr, and then fixes up the callers.
I chose unique_xmalloc_ptr rather than std::string because at a few
call points the xmalloc'd string is released and ownership transferred
elsewhere.
This patch found a few existing memory leaks. For example,
py-unwind.c called gdbpy_obj_to_string but never freed the result.
Built and regression tested on the buildbot.

gdb/testsuite: Introduce "proc_with_prefix"
While adding new tests to gdb.base/commands.exp, I noticed that the
file includes a bunch of individual testcases split into their own
procedures, and that none have ever been adjusted to use
with_test_prefix. Instead, each gdb_test/gdb_test_multiple/etc
invocation takes care of including the procedure name in the test
message, in order to make sure test messages are unique.
Simon convinced me that using the procedure name as prefix is not that
bad of an idea:
https://sourceware.org/ml/gdb-patches/2016-10/msg00020.html
This commit adds an IMO simpler alternative to
with_test_prefix_procname added by that patch -- a new
"proc_with_prefix" convenience proc that is meant to be used in place
of "proc", and then uses it in commands.exp. Procedures defined with
this automatically run their bodies under with_test_prefix $proc_name.
Here's a sample of the resulting gdb.sum diff:
[...]
-PASS: gdb.base/commands.exp: break factorial #3
-PASS: gdb.base/commands.exp: set value to 5 in test_command_prompt_position
-PASS: gdb.base/commands.exp: if test in test_command_prompt_position

tui-winsource: Allocate for actual lines only
The logic for allocating a TUI source window's content buffer allocates

tui-disasm: Fix line buffer size calculation
The code that fills the TUI disassembly window content first calculates
the maximum full length of a displayed disassembly line. This

so the bug does not cause any run-time failures, but unnecessary
confusion for the reader. This patch fixes the calculation.

tui-disasm: Fix window content buffer overrun
A user reported a GDB crash with TUI when trying to debug a function
with a long demangled C++ method name. It turned out that the logic for
displaying the TUI disassembly window has a bug that can cause a buffer
overrun, possibly overwriting GDB-internal data structures. In
particular, the logic performs an unguarded strcpy.
Another (harmless) bug in tui_alloc_source_buffer causes the buffer to
be two lines longer than needed. This may have made the crash appear
less frequently.
gdb/ChangeLog:
* tui/tui-disasm.c (tui_set_disassem_content): Fix line buffer
overrun due to unchecked strcpy.
gdb/testsuite/ChangeLog:
* gdb.base/tui-layout.c: New file.
* gdb.base/tui-layout.exp: Use tui-layout.c, to ensure that the
disassembly window contains very long lines.

Fix some error-handling bugs in python frame filters
While writing a Python frame filter, I found a few bugs in the current
frame filter code. In particular:
* One spot converts a Python long to a CORE_ADDR using PyLong_AsLong.
However, this can fail on overflow. I changed this to use
get_addr_from_python.
* Another spot is doing the same but with PyLong_AsUnsignedLongLong; I
changed this as well just for consistency.
* Converting line numbers can print "-1" if conversion from long
fails. This isn't fatal but just a bit ugly.
I've included a test case for the first issue. The line number one
didn't seem important enough to bother with.

get_addr_from_python. Check for errors when getting line number.

Remove parameter valaddr from la_val_print
Nowadays, we pass both val and return value of
value_contents_for_printing (val) to la_val_print. The latter is
unnecessary. This patch removes the second parameter of la_val_print,
and get valaddr in each language's implementation by calling
value_contents_for_printing. Since value_contents_for_printing calls
value_fetch_lazy, I also make VAL non-const.
Note that
- I don't clean up the valaddr usages in each language's routines,
- I don't remove valaddr from apply_ext_lang_val_pretty_printer, and
extension language ops apply_val_pretty_printer.
They can be done in followup patches.

Use get_frame_register_value instead of deprecated_frame_register_read
This patch calls get_frame_register_value instead of
deprecated_frame_register_read, so that we can pass
value_contents_for_printing to val_print. Both
get_frame_register_value and deprecated_frame_register_read call
frame_unwind_register_value indirectly, so no functionality is changed

Eliminate agent_expr_p; VEC -> std::vector in struct bp_target_info
After the previous patch, we end up with these two types with quite
similar, and potentially confusing names:
typedef gdb::unique_ptr<agent_expr> agent_expr_up;
/* Pointer to an agent_expr structure. */
typedef struct agent_expr *agent_expr_p;
The latter is only necessary to put agent_expr pointers in VECs. So
just eliminate it and use std::vector instead.

'struct agent_expr *' -> unique_ptr<agent_expr>
This patch makes the gen_* functions return a unique_ptr instead of
raw pointer:
typedef gdb::unique_ptr<agent_expr> agent_expr_up;
and then adjusts the codebase throughout to stop using
make_cleanup_free_agent_expr.
The cond_bytecode and cmd_bytecode fields of struct bp_location are
owning pointers, so they're changed to be unique_ptr's instead of raw
pointers.

Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls. Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers. And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.
The stopping point was once gdb built again. These doesn't seem to be
a way to reasonably split this out further.
Maybe-not-obvious changes:
- demangle_for_lookup returns a cleanup today. To get rid of that,
and avoid unnecessary string dupping/copying, this introduces a
demangle_result_storage type that the caller instantiates and
passes to demangle_for_lookup.
- Many methods returned a "char *" to indicate that the caller owns
the memory and must free it. Those are switched to return a
std::string instead. Methods that return a "view" into some
internal string return a "const char *" instead. I.e., we only
copy/allocate when necessary.

Use ui_file_as_string in gdb/compile/
Using ui_file_as_string would imply changing a few prototypes to pass
around source and object file names as std::string. Instead of that,
wrap those two in a new class. This ends up eliminating a small
wrinkle: get_new_file_names and compile_object_load have swapped
parameters. The former takes "source, objfile", while the latter
takes "objfile, source".

Clean up tracepoint.h/c:collection_list
Noticed we could do this while working on the expression_up change.
The main goal here was getting rid of the
encode_actions_and_make_cleanup / do_clear_collection_list cleanups.
While at it, uncrustify the code:
- Make collection_list a C++ class, with data members private (and
thus renamed m_...).
- Make related functions be member methods.
- Use std::vector instead of an open coding a vector implementation.
- Use std::sort instead of qsort.
- Rename the "list" member of collection_list, which is an incredibly
obfuscating name.
- Rename a couple other things here and there for clarify.
- Use "bool" more.

Introduce ui_file_as_string
ui_file_as_string is a variant of ui_file_xstrdup that returns a
std::string instead of a xmalloc'ed char *. The idea is using the new
function to eliminate "make_cleanup (xfree, ...)" cleanups
throughout.
Following patches will make use of this.

'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:
typedef gdb::unique_malloc_ptr<expression> expression_up;
and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.
Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.
[1] - I'd like to set the rule that types named with an "_up" suffix
are unique_ptr typedefs.
Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects. Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

breakpoint.c:commands_command_1 constification and cleanup
This is constification needed for next patch. Adjust
commands_command_1 to use std::string too because the "arg" parameter
is currently overwritten and then passed to make_cleanup. The
constification alone would trigger a compile error in the make_cleanup
call otherwise (passing const char * to void * parameter). Using
std::string gets rid of the cleanup in the first place, resulting in
simpler code.

Check for truncated registers in process_g_packet
While investigating an unrelated issue in remote.c I noticed that the
bound checking for 'g' packets was bogus:
The previous code would only check that the first byte of the register
was within bounds before passing the buffer to regcache_raw_supply.
If it turned out that the register in the 'g' packet was incomplete
then regcache_raw_supply would proceed to memcpy out-of-bounds.
Since the buffer is allocated with alloca it's relatively unlikely to
crash (you just end up dumping gdb's stack into the cache) but it's
still a bit messy.
I changed this logic to check for truncated registers and raise an
error if one is encountered. Hopefully it should make debugging
remote stubs a bit easier.

arc/nps400: Validate address type operands correctly
When we match against an address type operand within an instruction it
is important that we match exactly the right address type operand early
on, during the opcode selection phase. If we wait until the operand
insertion phase to check that we have the correct address operand, then
it is too late to select an alternative opcode. This becomes important
only when we have multiple opcodes with the same mnemonic, and operand
lists that differ only in the type of the address operands.
This commit fixes this issue, and adds some example instructions that
require this issue to be fixed (the instructions are identical except
for the address type operand).

set default-directory in dwarf-browse
I've been using dwarf-mode.el again recently and I found it mildly
annoying that the mode doesn't set default-directory. Setting it
means that operations in the dwarf-browsing buffer default to the
directory holding the object file being investigated.
This bumps the version number as well so that updating it via the
package manager works properly.

ld: Allow EXCLUDE_FILE to be used outside of the section list
Currently the EXCLUDE_FILE linker script construct can only be used
within the input section list, and applied only to the section pattern
immediately following the EXCLUDE_FILE. For example:
*.o (EXCLUDE_FILE (a.o) .text .rodata)
In this case all sections matching '.text' are included from all files
matching '*.o' but not from the file 'a.o'. All sections matching
'.rodata' are also included from all files matching '*.o' (incluing from
'a.o').
If the user wants to restrict the inclusion of section '.rodata' so that
this too is not taken from the file 'a.o' then the above example must be
extended like this:
*.o (EXCLUDE_FILE (a.o) .text EXCLUDE_FILE (a.o) .rodata)
However, due to the internal grammar of the linker script language the
snippet 'EXCLUDE_FILE (a.o) .text' is parsed by a pattern called
'wildcard_spec'. The same 'wildcard_spec' pattern is also used to parse
the input file name snippet '*.o' in the above examples. As a result of
this pattern reuse within the linker script grammar then the following
is also a valid linker script construct:
EXCLUDE_FILE (a.o) *.o (.text .rodata)
However, though the linker accepts this without complaint the
EXCLUDE_FILE part is silently ignored and has no effect.
This commit takes this last example and makes it a useful, valid,
construct. The last example now means to include sections '.text' and
'.rodata' from all files matching '*.o' except for the file 'a.o'.
If the list of input sections is long, and the user knows that the file
exclusion applies across the list then the second form might be a
clearer alternative to replicating the EXCLUDE_FILE construct.
I've added a set of tests for EXCLUDE_FILE to the linker, including
tests for the new functionality.

ld: Create test object files based on source file name
When creating object files during testing, base the name of the object
file on the name of the source file, rather than using dump0.o,
dump1.o, etc. There's a few places where we have multiple source
files with the same name but in different directories, in these cases,
even after this change, we still add a numerical suffix to make the
object file names unique. So if we have 'foo/src.s' and 'bar/src.s',
we will create object files 'src.o' and 'src1.o'.
Update the few tests that hard code the object file name into the
expected test results.

ld/xc16x: This target does not support -shared
Add the xc16x-elf target to the list of targets that do not support
the -shared option. Being missing from this list was causing the
linker to add '-z norelro' to the link line of many tests, which in
turn caused these tests to fail.

[ARC] Fix ldbit test on 32-bit systems
The long immediate operand chosen for one of the ldbit tests is
equivalent to a small negative value that would fit inside an s9
operand, leading to the assembler to choose an unexpected (but
legitimate) encoding of the instruction on 32-bit systems, and
therefore causing the test to fail. This commit fixes the test by
changing the offending limm value so that it can no longer be
interpreted as an s9 operand.
gas/ChangeLog:
* testsuite/gas/arc/nps400-6.s: Change ldbit tests so that
limm operands are out of the range of an s9, in order to fix
the test.
* testsuite/gas/arc/nps400-6.d: Updated to match new expected
output.

arc: Change max instruction length to 64-bits
The current handling for arc instructions longer than 32-bits is all
handled as a special case in both the assembler and disassembler.
The problem with this approach is that it leads to code duplication,
selecting a long instruction is exactly the same process as selecting a
short instruction, except over more bits, in both cases we select based
on bit comparison, and initial operand insertion and extraction.
This commit unifies both the long and short instruction worlds,
converting the core opcodes library from being largely 32-bit focused,
to being largely 64-bit focused.
The changes are, on the whole, not too much. There's obviously a lot of
type changes but otherwise the bulk of the code just works. Most of the
actual functional changes are to code that previously handled the longer
48 or 64 bit instructions. The insert/extract handlers for these have
now been brought into line with the short instruction insert/extract
handlers.
All of the special case handling code that was previously added has now
been removed again. Overall, this commit reduces the amount of code in
the arc assembler and disassembler.

A few masks were incorrect, there were opcode bits that lives outside of
the instruction mask, the effected instructions are decode1, zncv, and
efabgt.
Previously these instructions would assemble and disassemble correctly,
and a correctly encoded binary should behave no differently. The only
difference would be seen in a few incorrectly encoded binaries,
previously these would have decoded to the above instructions, while now
they will not.

Remove GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION
Both of them are used in conversion. We can remove them since the
conversion is done.
There are many architectures only have one breakpoint instruction,
so their gdbarch methods breakpoint_kind_from_pc and
sw_breakpoint_from_kind look very similar. Instead of macro, we
use template "template <size_t, const gdb_byte *> struct bp_manipulation"
for these architectures. In order to use template, I also change
breakpoint instruction of type "static const gdb_byte[]" to
"constexpr gdb_byte[]", and rename them to ARCH_break_insn.

New gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kind
This patch adds two gdbarch methods breakpoint_kind_from_pc and
sw_breakpoint_from_kind, and uses target_info.placed_size as "kind"
of the breakpoint. This patch updates the usages of
target_info.placed_size.
The "kind" of a breakpoint is determined by gdbarch rather than
target, so we have gdbarch method breakpoint_kind_from_pc, and we
should set target_info.placed_size out of each implementation of
target to_insert_breakpoint. In this way, each target doesn't have
to set target_info.placed_size any more.
This patch also sets target_info.placed_address before
target_insert_breakpoint too, so that target to_insert_breakpoint
can use it, see record_full_insert_breakpoint.
Before we call target_insert_breakpoint, we set
target_info.placed_address and target_info.placed_size like this,
CORE_ADDR addr = bl->target_info.reqstd_address;
bl->target_info.placed_size = gdbarch_breakpoint_kind_from_pc (bl->gdbarch, &addr);
bl->target_info.placed_address = addr;
return target_insert_breakpoint (bl->gdbarch, &bl->target_info);
target_insert_breakpoint may fail, but it doesn't matter to the "kind"
and "placed_address" of a breakpoint. They should be determined by
gdbarch.

gdbarch_breakpoint_from_pc doesn't return NULL
gdbarch_breakpoint_from_pc doesn't return NULL except for
ia64_breakpoint_from_pc, and we checked its return value in three

ppc_linux_memory_remove_breakpoint, gdbarch_breakpoint_from_pc never

Fix dwarf_expr_context method regressions
This fixes some regressions found in the patch to convert
dwarf_expr_context to use methods. Specifically:
* get_base_type could erroneously throw; this was rewritten to move
the size checks into the only spot needing them.
* Previously the "symbol needs frame" implementation reused th
"cfa" function for the get_frame_pc slot; this reimplements
it under the correct name.
* Not enough members were saved and restored in one implementation
of push_dwarf_reg_entry_value; this patch fixes this oversight
and also takes the opportunity to remove an extraneous structure
definition.

BFD: Fix double BFD_FAIL calls in `bfd_default_reloc_type_lookup'
Break out of the outer switch statement once the inner switch for the
BFD_RELOC_CTOR relocation has been processed, preventing double BFD_FAIL
calls from being made, once from the inner switch and then again from
the default case of the outer switch.
Noticed with a `-Wimplicit-fallthrough' build error reported by a recent
GCC version:

gdb/doc: Remove mention of vCont's default actions
Discussion with qemu folks suggests that the vCont description could
be even simpler and clearer. Given we now say:
For each inferior thread, the leftmost action with a matching
thread-id is applied.
There's really no need to even talk about "default" actions, which
raises doubts about whether "default" is special in some way (it's
not).

gdb: Require C++11
Use AX_CXX_COMPILE_STDCXX to detect if the compiler supports C++11,
and if -std=xxx switches are necessary to enable C++11.
We need to tweak AX_CXX_COMPILE_STDCXX a bit though. Pristine
upstream AX_CXX_COMPILE_STDCXX appends -std=gnu++11 to CXX directly.
That doesn't work for us, because the top level Makefile passes CXX
down to subdirs, and that overrides whatever gdb/Makefile may set CXX
to. The result would be that a make invocation from the build/gdb/
directory would use "g++ -std=gnu++11" as expected, while a make
invocation at the top level would not.
So instead of having AX_CXX_COMPILE_STDCXX set CXX directly, tweak it
to AC_SUBST a separate variable -- CXX_DIALECT -- and use '$(CXX)
(CXX_DIALECT)' to compile/link.
Confirmed that this enables C++11 starting with gcc 4.8, the first gcc
release with full C++11 support.
Also confirmed that configure errors out gracefully with older GCC
releases:
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features by default... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=gnu++11... no

checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with +std=c++11... no
checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -h std=c++11... no
configure: error: *** A compiler with support for C++11 language features is required.

make[1]: *** [configure-gdb] Error 1
make[1]: Leaving directory '/home/pedro/brno/pedro/gdb/mygit/cxx-convertion/build-gcc-4.7'
If we need to revert back to making C++11 optional, all that's
necessary is to change the "mandatory" to "optional" in configure.ac
and regenerate configure (both gdb and gdbserver).

Make gdb.base/foll-exec.exp test pattern more general
Testing a powerpc toolchain running gdbserver on the other end i noticed a
failure in gdb.base/foll-exec.exp. Turns out gdb is outputting a slightly
different pattern due to the presence of debug information.
--
foll-exec is about to execlp(execd-prog)...^M
Continuing.^M
process 21222 is executing new program: gdb.d/outputs/gdb.base/foll-exec/execd-prog^M
^M
Catchpoint 2 (exec'd gdb.d/outputs/gdb.base/foll-exec/execd-prog), _start () at ../sysdeps/powerpc/powerpc32/dl-start.S:32^M
--
Notice the presence of source file information.
Now, on my local machine, i get this:
--
foll-exec is about to execlp(execd-prog)...^M
Continuing.^M
process 9285 is executing new program: gdb/testsuite/outputs/gdb.base/foll-exec/execd-prog^M
^M
Catchpoint 2 (exec'd gdb/testsuite/outputs/gdb.base/foll-exec/execd-prog), 0x00007ffff7dd7cc0 in ?? () from /lib64/ld-linux-x86-64.so.2^M
--
So the output differs slightly and the testcase is actually expecting only
the second form with the "in" anchor.
This patch removes the "in" pattern and lets the test match both kinds of
output.

Fix gdb.base/maint.exp regressions
This commit fixes these regressions:
FAIL: gdb.base/maint.exp: mt set per on for expand-symtabs
FAIL: gdb.base/maint.exp: maint set per-command on
caused by commit 1e3b796d58ac ("Change command stats reporting to use
class").
gdb.log shows that the command stats are now printing garbage:
(gdb) mt set per on
Command execution time: -6.-419590 (cpu), 1467139648.-7706296840 (wall)
Space used: 9809920 (-33276528 for this command)
(gdb) FAIL: gdb.base/maint.exp: mt set per on for expand-symtabs
while there should have been no output at all.
The stats printing is done from within the scoped_command_stats's
destructor, depending on whether some flags in the object are set.
The problem is simply that scoped_command_stats's ctor misses clearing
those flags on some paths.
Since scoped_command_stats objects are allocated on the stack, whether
you'll see the regression simply depends on whatever happens to
already be on the stack space the object occupies.

btrace: bridge gaps
Most of the time, the trace should be in one piece. This case is handled fine
by GDB. In some cases, however, there may be gaps in the trace. They result
from trace decode errors or from overflows.
A gap in the trace means we lost an unknown amount of trace. Gaps can be very
small, such as a few instructions in the same function, or they can be rather
big. We may, for example, lose a few function calls or returns. The trace may
continue in a different function and we likely don't know how we got there.
Even though we can't say how the program executed across a gap, higher levels
may not be impacted too much by it. Let's assume we have functions a-e and a
trace that looks roughly like this:
a
\
b b
\ /
c <gap> c
/
d d
\ /
e
Even though we can't say for sure, it is likely that b and c are the same
function instance before and after the gap. This patch is trying to connect
the c and b function segments across the gap.
This will add a to the back trace of b on the right hand side. The changes are
reflected in GDB's internal representation of the trace and will improve:
- the output of "record function-call-history /c"
- the output of "backtrace" in replay mode
- source stepping in replay mode
will be improved indirectly via the improved back trace
I don't have an automated test for this patch; decode errors will be fixed and
overflows occur sporadically and are quite rare. I tested it by hacking GDB to
provoke a decode error and on the expected gap in the gdb.btrace/dlopen.exp
test.
The issue is that we can't predict where we will be able to re-sync in case of
errors. For the expected decode error in gdb.btrace/dlopen.exp, for example, we
may be able to re-sync somewhere in dlclose, in test, in main, or not at all.
Here's one example run of gdb.btrace/dlopen.exp with and without this patch.

It worked nicely in this case but it may, of course, also lead to weird

It works best when the gap is small and the trace pieces are long.

btrace: preserve function level for unexpected returns
When encountering a return for which we have not seen a corresponding call, GDB
starts a new back trace from level -1, i.e. from the level of the first function
in the trace.
In the presence of trace gaps, this may cause some rather big jump.
(gdb) record function-call-history /c 192, +8
192 sbrk
193 brk
194 __x86.get_pc_thunk.bx
195 brk
196 __kernel_vsyscall
197 [disabled]
198 __kernel_vsyscall
199 brk
200 sbrk
This doesn't help to make things more clear. Let's remain on the same level
instead.
(gdb) record function-call-history /c 192, +8
192 sbrk
193 brk
194 __x86.get_pc_thunk.bx
195 brk
196 __kernel_vsyscall
197 [disabled]
198 __kernel_vsyscall
199 brk
200 sbrk
In this case it will look like we were able to connect the trace parts across
the disabled gap. We were not. More work is required to achieve this.
In the general case, the function-call history for the two trace parts won't
match. They may be off by a few levels or they may be entirely different. All
this patch does is to preserve the indentation level of the record
function-call-history command.
The disabled gap is caused by a sysenter not returning to the next instruction.

I've seen this on 32-bit Fedora 23. I have not investigated what causes this
and whether we can avoid the gap in the first place. Let's first try to make
GDB handle such gaps more gracefully.

btrace: update tail call heuristic
An unconditional jump to the start of a function typically indicates a tail
call.
If we can't determine the start of the function at the destination address, we
used to treat it as a tail call, as well. This results in lots of tail calls
for code for which we don't have symbol information.
Restrict the heuristic to only consider jumps as tail calls that switch
functions in the case where we can't determine the start of a function. This
effectively disables tail call detection for code without symbol information.

btrace: allow leading trace gaps
GDB ignores trace gaps from decode errors or overflows at the beginning of the
trace. There isn't really a gap in the trace; the trace just starts a bit
later than expected.
In cases where there is no trace at all or where the trace is smaller than
expected, this may hide the reason for the missing trace.
Allow leading trace gaps. They will be shown as decode warnings and by the
record function-call-history command.

Also add a warning when decoding the trace and print the instruction number
preceding the trace gap in that warning message. It looks like this:

Get pending events in random
Nowadays, we select events to be reported to GDB in random, however
that is not enough when many GDBserver internal events (not reported
to GDB) are generated.
GDBserver pulls all events out of kernel via waitpid, and leave them
pending. When goes through threads which have pending events,
GDBserver uses find_inferior to find the first thread which has
pending event, and consumes it. Note that find_inferior always
iterate threads in a fixed order. If multiple threads keep hitting
GDBserver breakpoints, range stepping with single-step breakpoint for
example, threads in the head of the thread list are more likely to be
processed and threads in the tail are starved. This causes some timeout
fails in gdb.threads/non-stop-fair-events.exp when range stepping is
enabled on arm-linux.
This patch fixes this issue by randomly selecting pending events. It
adds a new function find_inferior_in_random, which iterates threads
which have pending events randomly.

gas/arc: Don't rely on bfd list of cpu type for cpu selection
In the ARC assembler, when a cpu type is specified using the .cpu
directive, we rely on the bfd list of arc machine types in order to
validate the cpu name passed in.
This validation is only used in order to check that the cpu type passed
to the .cpu directive matches any machine type selected earlier on the
command line. Once that initial check has passed a full check is
performed using the assemblers internal list of know cpu types.
The problem is that the assembler knows about more cpu types than bfd,
some cpu types known by the assembler are actually aliases for a base
cpu type plus a specific set of assembler extensions. One such example
is NPS400, though more could be added later.
This commit removes the need for the assembler to use the bfd list of
machine types for validation. Instead the error checking, to ensure
that any value passed to a '.cpu' directive matches any earlier command
line selection, is moved into the function arc_select_cpu.
I have taken the opportunity to bundle the 4 separate static globals
that describe the currently selected machine type into a single
structure (called selected_cpu).

PR 20569, segv in follow_exec
The following testcases make GDB crash whenever an invalid sysroot is
provided, when GDB is unable to find a valid path to the symbol file:
gdb.base/catch-syscall.exp
gdb.base/execl-update-breakpoints.exp
gdb.base/foll-exec-mode.exp
gdb.base/foll-exec.exp

gdb.threads/non-ldr-exc-2.exp
gdb.threads/non-ldr-exc-3.exp
gdb.threads/non-ldr-exc-4.exp
gdb.threads/thread-execl.exp
The immediate cause of the segv is that follow_exec is passing a NULL
argument (the result of exec_file_find) to strlen.
However, the problem is deeper than that: follow_exec simply isn't
prepared for the case where sysroot translation fails to locate the
new executable. Actually all callers of exec_file_find have bugs due
to confusion between host and target pathnames. This commit attempts
to fix all that.
In terms of the testcases that were formerly segv'ing, GDB now prints
a warning but continues execution of the new program, so that the
tests now mostly FAIL instead. You could argue the FAILs are due to a
legitimate problem with the test environment setting up the sysroot
translation incorrectly.
A new representative test is added which exercises the ne wwarning
code path even with native testing.
Tested on x86_64 Fedora 23, native and gdbserver.

Make symfile_add_flags and objfile->flags strongly typed
This makes these flag types be "enum flag" types. The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.
This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:
@@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)

reinit_frame_cache ();
- if ((flags & SYMFILE_NO_READ) == 0)
+ if ((add_flags & SYMFILE_NO_READ) == 0)
set_initial_language ();
}
Above, "flags" are objfile flags, not symfile_add_flags. So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...
I moved the flags definitions to separate files to break circular
dependencies.

gdb: Coalesce/aggregate (async) vCont packets/actions
Currently, with "maint set target-non-stop on", that is, when gdb
connects with the non-stop/asynchronous variant of the remote
protocol, even with "set non-stop off", GDB always sends one vCont
packet per thread resumed. This patch makes GDB aggregate and
coalesce vCont packets, so we send vCont packets like "vCont;s:p1.1;c"
in non-stop mode too.
Basically, this is done by:
- Adding a new target method target_commit_resume that is called
after calling target_resume one or more times. When resuming a
batch of threads, we'll only call target_commit_resume once after
calling target_resume for all threads.
- Making the remote target defer sending the actual vCont packet to
target_commit_resume.
Special care must be taken to avoid sending a vCont action with a
"wildcard" thread-id (all threads of process / all threads) when that
would resume threads/processes that should not be resumed. See
remote_commit_resume comments for details.
Unlike all-stop's remote_resume implementation, this handles the case
of too many actions resulting in a too-big vCont packet, by flushing
the vCont packet and starting a new one.
E.g., imagining that the "c" action in:
vCont;s:1;c
overflows the packet buffer, we split the actions like:
vCont;s:1
vCont;c
Tested on x86_64 Fedora 20, with and without "maint set
target-non-stop on".
Also tested with a hack that makes remote_commit_resume flush the vCont
packet after every action appended (which caught a few bugs).

gdbserver: Leave already-vCont-resumed threads as they were
Currently GDB never sends more than one action per vCont packet, when
connected in non-stop mode. A follow up patch will change that, and
it exposed a gdbserver problem with the vCont handling.
For example, this in non-stop mode:
=> vCont;s:p1.1;c
<= OK
Should be equivalent to:
=> vCont;s:p1.1
<= OK
=> vCont;c
<= OK
But gdbserver currently doesn't handle this. In the latter case,
"vCont;c" makes gdbserver clobber the previous step request. This
patch fixes that.
Note the server side must ignore resume actions for the thread that
has a pending %Stopped notification (and any other threads with events
pending), until GDB acks the notification with vStopped. Otherwise,
e.g., the following case is mishandled:
#1 => g (or any other packet)
#2 <= [registers]
#3 <= %Stopped T05 thread:p1.2
#4 => vCont s:p1.1;c
#5 <= OK
Above, the server must not resume thread p1.2 when it processes the
vCont. GDB can't know that p1.2 stopped until it acks the %Stopped
notification. (Otherwise it wouldn't send a default "c" action.)
(The vCont documentation already specifies this.)
Finally, special care must also be given to handling fork/vfork
events. A (v)fork event actually tells us that two processes stopped
-- the parent and the child. Until we follow the fork, we must not
resume the child. Therefore, if we have a pending fork follow, we
must not send a global wildcard resume action (vCont;c). We can still
send process-wide wildcards though.
(The comments above will be added as code comments to gdb in a follow
up patch.)

gdb: Free inferior->priv when inferior exits
(Where "exits" includes being killed or detached.)
Nothing is clearing inferior->priv currently. This is a problem if we
change the inferior's process_stratum targets in a single debug
session. This field is currently only used by darwin-nat.c, but a
follow up patch will make remote.c use it too. Without the fix,
remote.c might end up mistaking the priv object allocated by
darwin-nat.c with its own.

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration

extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':

Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid

Fixed by casting pid_t to long and printing it as such.

This apparently is due to - man gcc - -fsplit-stack:
When code compiled with -fsplit-stack calls code compiled without
-fsplit-stack, there may not be much stack space available for the
latter code to run. If compiling all code, including library code,
with -fsplit-stack is not an option, then the linker can fix up these
calls so that the code compiled without -fsplit-stack always has
a large stack. Support for this is implemented in the gold linker in
GNU binutils release 2.21 and later.

Convert dwarf_expr_context_funcs to methods
This patch converts the function pointers in dwarf_expr_context_funcs
into methods on dwarf_expr_context, and then updates the various
implementations and callers to follow.
NB this patch uses "override" (which caught a couple of renaming bugs
during development) -- but this is C++11, so this patch at least has
to wait for Pedro's patch that adds the OVERRIDE macro.
After this patch it would be possible to do one more, that makes
various members of dwarf_expr_context "protected"; but I haven't done
this.

Some cleanup removal in dwarf2loc.c
This removes some cleanups and manual allocation handling in
dwarf2loc.c with std::vector. Note that this patch has a case where
the vector would normally fall into the "use gdb::unique_ptr"

I moved the initialization into the constructor call, for further
code savings.

Use RAII to save and restore scalars
This patch replaces many (but not all) uses of

Fix symbol table file name on AIX
When xlc -qfuncsect or gcc -ffunction-sections options is used in AIX,
each function csect is associated with each psymtab, so each psymtab
will have it's corresponding filename entries set.
If the pst filename isn't set then we will be seeing the below output
when we set a breakpoint.
(gdb) br main
Breakpoint 1 at 0x10000374: file _start_ , line 18.
With the fix it will be.

gdb: no longer define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS
My gnulib fix at:
https://lists.gnu.org/archive/html/bug-gnulib/2015-11/msg00010.html
was merged upstream meanwhile and our gnulib copy now includes it.
As a concidence, Kevin was telling me today that these macros are
causing a build problem on FreeBSD:
common/common-defs.h:47:0: error: "__STDC_CONSTANT_MACROS" redefined [-Werror]
#define __STDC_CONSTANT_MACROS 1
/usr/include/sys/cdefs.h:408:0: note: this is the location of the previous definition
#define __STDC_CONSTANT_MACROS
(and a similar error for __STDC_LIMIT_MACROS)
The problem seems to be that we should be defining these input macros
before including any system header, but, we're not.
So let's just revert e063da67902e ([C++] Define __STDC_CONSTANT_MACROS
/ __STDC_LIMIT_MACROS for stdint.h). If this causes a problem
somewhere, we can re-define the macros higher up in the file, before
system headers are included.

2016-10-18 Pedro Alves <palves@redhat.com>
* common/common-defs.h (__STDC_CONSTANT_MACROS)
(__STDC_LIMIT_MACROS): Delete.

I tried building gdb with G++ 4.7 and CXX="g++ -std=gnu+11", and that
tripped on a build error:

Updating gnulib to current master fixes it, since it brings in this
fix:
http://lists.gnu.org/archive/html/bug-gnulib/2016-04/msg00000.html
Our last update was in August 2015. This doesn't bring in much added
baggage, it's mostly bug fixes. It pulled in the "limits-h" module as
automatic dependency, and given that looks potentially useful I added
it to the set of modules we require.
Tested on x86_64 Fedora 23, with g++ 4.7 and g++ 5.3, native and gdbserver.

Introduce gdb::unique_ptr
Many make_cleanup uses in the code base are best eliminated by using a
"owning" smart pointer to manage ownership of the resource
automatically.
The question is _which_ smart pointer.
GDB currently supports building with a C++03 compiler. We have
std::auto_ptr in C++03, but, as is collective wisdom by now, that's
too easy to misuse, and has therefore been deprecated in C++11 and
finally removed in C++17.
It'd be nice to be able to use std::unique_ptr instead, which is the
modern, safe std::auto_ptr replacement in C++11.
In addition to extra safety -- moving (i.e., transfer of ownership of
the managed pointer between smart pointers) must be explicit --
std::unique_ptr has (among others) one nice feature that std::auto_ptr
doesn't --- ability to specify a custom deleter as template parameter.
In gdb's context, that allows easily creating a smart pointer for
memory allocated with xmalloc -- the smart pointer then knows to
release with xfree instead of delete. This is particularly
interesting when managing objects allocated in C libraries, and also,
for C++-fying parts of GDB that interact with other parts that still
return objects allocated with xmalloc.
Since std::unique_ptr's API is quite nice, and eventually we'd like to
move to C++11, this patch adds a C++03-compatible smart pointer that
exposes the subset of the std::unique_ptr API that we're interested
in. An advantage is that whenever we start requiring C++11, we won't
have to learn a new API. Meanwhile, this allows continuing to support
building with a C++03 compiler.
Since C++03 doesn't support rvalue references (boost gets close to
emulating them, but it's not fully transparent to user code), the
C++03 std::unique_ptr emulation here doesn't try hard to prevent
accidentally moving, which is where most of complication of a more
thorough emulation would be. Instead, we rely on the fact that GDB
will be usually compiled with a C++11 compiler, and use the real
std::unique_ptr in that case to catch such accidental moves. IOW, the
goal here is to allow code that would be correct using std::unique_ptr
to be equally correct in C++03 mode, and, just as efficient.
The C++03 version was originally based on GCC 7.0's std::auto_ptr and
then heavily customized to behave more like C++11's std::unique_ptr:
- Support for custom (stateless) deleters. (Support for stateful
deleters could be added, if necessary.)
- unique_ptr<T[]> partial specialization (auto_ptr<T> does not know
to use delete[]).
- Support for all of 'ptr != NULL', 'ptr == NULL' and 'if (ptr)'
using the safe bool idiom to emulate C++11's explicit bool
operator.
- There's no nullptr in C++03, so this allows initialization and
assignment from NULL instead (std::auto_ptr allows neither).
- Variable names un-uglified (ie., no leading __ prefix everywhere).
- Formatting made to follow GDB's coding conventions, including
comment style.
- Converting "move" constructors done differently in order to truly
support:
unique_ptr<Derived> func_returning_unique_ptr (.....);
...
unique_ptr<Base> ptr = func_returning_unique_ptr (.....);
At this point, it no longer shares much at all with the original file,
but, that's the history.
See comments in the code to find out more.
I thought of putting the "emulation" / shim in the "std" namespace, so
that when we start requiring C++11 at some point, no actual changes to
users of the smart pointer throughout would be necessary. Putting
things in the std namespace is technically undefined, however in
practice it doesn't cause any issue with any compiler. However,
thinking that people might be confused with seeing std::unique_ptr and
thinking that we're actually requiring C++11 already, I put the new
types in the "gdb" namespace instead.
For managing xmalloc pointers, this adds a gdb::unique_xmalloc_ptr<T>
"specialization" with a custom xfree deleter.
No actual use of any smart pointer is introduced in this patch.
That'll be done in following patches.
Tested (along with the rest of the series) on:
- NetBSD 5.1 (gcc70 on the compile farm), w/ gcc 4.1.3
- x86-64 Fedora 23, gcc 5.3.1 (gnu++03)
- x86-64 Fedora 23, and gcc 7.0 (gnu++14)

Make sure the architecture is `bfd_arch_i386' before handling the `set
mpx' and `show mpx' commands, avoiding the issue with `i386_mpx_enabled'
interpreting `gdbarch->tdep' according to the `struct gdbarch_tdep'

it may have a different layout and cause GDB to crash or at least

This is a regression caused by commit cda6c55bd399 (Turn wchar
iterator into a class). The problem is that iconv_t is now exposed in
gdb/charset.h, while before it was only used in gdb/charset.c.
gdb/charset.c, under #ifdef PHONY_ICONV, does:
#undef iconv_t
#define iconv_t int
So it seems the simplest is to use 'int' in the header file too.

[ARC] Disassembler: fix LIMM detection for short instructions.
The ARC (short) instructions are using a special register number to
indicate is the instruction uses a long immediate (LIMM). In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions. However, for the ARCv2 processors,
this LIMM indicator is 0x1E.
This patch fixes the LIMM detection for ARCv1 ISA and adds two tests.

Convert tid_range_parser and get_number_or_range to classes
This converts tid_range_parser and get_number_or_range to be classes.
The various tid_range_parser_* and get_number_or_range_* functions
become methods on the respective classes. Then it updates the users
to follow.
The rationale for the change is that this provides better
encapsulation. For example, this forced me to think of a better
interface between tid_range_parser and get_number_or_range, since the
former peeked into the latter's internals a bit too much. That ended
up resulting mostly in these two not-just-straight-1-1 changes:
void
-tid_range_parser_skip (struct tid_range_parser *parser)
+tid_range_parser::skip_range ()
{
...
- tid_range_parser_init (parser, parser->range_parser.end_ptr,
- parser->default_inferior);
+ m_range_parser.skip_range ();
+ init (m_range_parser.string (), m_default_inferior);
}
and:
/* If we successfully parsed a thread number or finished parsing a
thread range, switch back to assuming the next TID is
inferior-qualified. */
- if (parser->range_parser.end_ptr == NULL
- || parser->range_parser.string == parser->range_parser.end_ptr)
+ if (!m_range_parser.in_range ())
{
For the same reason (encapsulation), this moves the enum
tid_range_state definition to within the tid_parser class's scope,
since that is private implementation detail.
While at it, switch to use "bool" for booleans.

Fixup gdb.python/py-value.exp for bare-metal aarch64-elf
I noticed that testing aarch64-elf gdb with a physical board
ran into issues with gdb.python/py-value.exp. Further investigation showed
that we were actually trying to dereference a NULL pointer (argv) when trying
to access argv[0].
Being bare-metal, argv is not guaranteed to be valid. So we need to make sure
argv is sane before accessing argv[0].
The following patch fixes up the test program to check for a NULL argv and also
improves the testcase a bit so it doesn't have to work with a hardcoded argc
value.
Regression-tested on x86-64 Ubuntu 16.04.
gdb/testsuite/ChangeLog:
2016-10-12 Luis Machado <lgustavo@codesourcery.com>
* gdb.python/py-value.c (main): Check if argv is NULL before using it.
* gdb.python/py-value.exp (test_value_in_inferior): Don't use hardcoded
argc values.
Add 1 to argc so we guarantee distinct initial/modified argc values.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.
binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address. If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

Always descend into output section statements in lang_do_assignments
See https://sourceware.org/ml/binutils/2016-07/msg00091.html
This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols
that ought to remain global.
The difficulty with always descending into output section statements
is that symbols defined by the script in such statements don't have
a bfd section when lang_do_assignments runs early in the link process.
There are two approaches to curing this problem. Either we can
create the bfd section early, or we can use a special section. This
patch takes the latter approach and uses bfd_und_section. (Creating
bfd sections early results in changed output section order, and thus
lots of testsuite failures. You can't create all output sections
early to ensure proper ordering as KEEP then stops empty sections
from being stripped.)
The wrinkle with this approach is that some code that runs at
gc-sections time needs to be made aware of the odd defined symbols
using bfd_und_section.

S/390: Move binary start to 16M.
Turned out that by moving the binary start to 256M I've hit a case with
potentially a lot of aliasing in the branch target buffer between
binaries and shared libs. So moving on.
Tested on s390x. No regressions.

MIPS64: Adjust cfi* testcases.
The CFI* testcases fail on MIPS64 because the augmentation string does
not match the regexp. This is because MIPS64 doesn't use the default of
4 for DWARF2_FDE_RELOC_SIZE which ends up as "b" in the augmentation
string. MIPS64 uses the address size which is 8 resulting in "c".
Adding c to the regexp fixes a couple of them. Others also need
adjustments in the FDE header lines due to different
sizes/offsets.

Remove v850_dbtrap_breakpoint_from_pc
v850 has two functions to install to gdbarch_breakpoint_from_pc,
and it selects one according to info.bfd_arch_info->mach. However,
we can select the kind/length of breakpoint instruction inside
v850_breakpoint_from_pc by gdbarch_bfd_arch_info (gdbarch)->mach.
This patch is to do that, and remove v850_dbtrap_breakpoint_from_pc.

Auto-generated dependencies for rx-parse.o and rl78-parse.o
I noticed a while ago that the rx-elf gas gprel test regressed for no
apparent reason. It turns out that the problem was rx-parse.y using
BFD_RELOC_RX_* values, which may change when other targets add new
relocs. If rx-parse.o doesn't depend on bfd.h, it won't be recompiled.

python: accept address and explicit locations in gdb.decode_line
The gdb.decode_line python function is documented to support the same location

Instead of creating a linespec location directly, create the location via
string_to_event_location_basic.

Pass link_info to _bfd_merge_private_bfd_data
Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker

for --fatal-warnings support before I decided a better way was the
patch commit 4519d071.

Remove Java support
This patch removes the Java support from gdb. gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.
Built and regtested on x86-64 Fedora 24.

mips-tdep: Make FCRs always 32-bit
Fix a regression from commit f8b73d13b7ca ("Target-described register
support for MIPS"),
<https://sourceware.org/ml/gdb-patches/2007-05/msg00340.html>,
<https://sourceware.org/ml/gdb-patches/2007-06/msg00256.html>, which
caused Floating Point Control Registers (FCRs) to be shown as 64-bit
with 64-bit targets.
This came from the legacy register format where all raw registers
matched the width of the architecture regardless of their actual size.
The correct size was then set in `mips_register_type' for cooked
registers presented to the user, which in the case of FCRs meant the
cooked size was always forced to 32 bits, reflecting their actual
hardware size, even though the raw format carried them in 64-bit
quantities on 64-bit targets. The upper 32 bits carried in the raw FCR
format have always been don't-cares, not actually retrieved from
hardware and never written back.
With the introduction of XML register descriptions the layout of
previously defined raw registers has been preserved, so as to keep
existing register handling code unchanged and make it easier for GDB and
`gdbserver' to interact with each other whether neither, either or both
parties talking over RSP support XML register descriptions. For the
XML-described case however `mips_register_type' is not used in raw to
cooked register conversion, so any special cases coded there are not
taken into account.
Instead a new function, `mips_pseudo_register_type', has been introduced
to handle size conversion, however lacking the special case for FCRs for
the Linux and the now defunct IRIX target. The correct size has been
maintained for embedded targets however, due to the bundling of FCRs
with the embedded registers under the `rawnum >= MIPS_EMBED_FP0_REGNUM +
32' condition.
Add the missing case to `mips_pseudo_register_type' then, referring to
the FCR indices explicitly, and observing that between
`MIPS_EMBED_FP0_REGNUM + 32' and `MIPS_FIRST_EMBED_REGNUM' there is an
unused register slot whose contents are ignored so with the removal of
embedded FCRs from under that condition we don't have to care about it
and we can refer to the embedded registers starting from
MIPS_FIRST_EMBED_REGNUM instead.
Add a test case too so that we have means to check automatically that
the correct user-visible size of FCRs is maintained.

Fix PR11094: JIT breakpoint is not properly recreated on reruns

This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.
If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):
(gdb) maint info breakpoints
Num Type Disp Enb Address What
[...]
-8 jit events keep y <PENDING> inf 1
[...]
But that's incorrect. GDB should have managed to recreate the JIT
breakpoint's location for the second run. So the problem is
elsewhere.
The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:
static int
jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
struct jit_program_space_data *ps_data)
{
[...]
if (ps_data->cached_code_address == addr)
return 0;
[...]
delete_breakpoint (ps_data->jit_breakpoint);
[...]
ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);
Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.
The test that was originally added for PR11094 doesn't trip on this
because:
#1 - It doesn't test the case of the JIT descriptor's address _not_
changing between reruns.
#2 - And then it doesn't do "maint info breakpoints", or really
anything with the JIT at all.
#3 - and even then, to trigger the problem the JIT descriptor needs
to be in a separate library, while the current test puts it in
the main program.
The patch extends the test to cover all combinations of these
scenarios.

Fix a few gdb.base/jit-simple.exp problems
I noticed that we sometimes get this:
(gdb) print &__jit_debug_descriptor
$1 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
[...]
(gdb) run
[...]
Starting program: build/gdb/testsuite/outputs/gdb.base/jit-simple/jit-simple
Unsupported JIT protocol version 4 in descriptor (expected 1)
Breakpoint 2, main () at src/gdb/testsuite/gdb.base/jit-simple.c:36
36 return 0;
(gdb) print &__jit_debug_descriptor
$2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.
Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.
The test doesn't catch any of this because it doesn't compare
before/after addresses.
And then notice the "blah 1" test messages. "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time. :-)
The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run". However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded. (This is an old problem out of scope of this series.) If
that happens, then GDB ends up using the wrong symbols for the program
that it spawns, reads the JIT descriptor out of the wrong address,
finds garbage, and prints that "unsupported version" notice.
Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

The .exp patch is an obvious typo fix I think. The regex was written to

the purpose of this testfile.
gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

Allow DW_OP_GNU_uninit in dwarf_expr_require_composition
In DWARF expression handling, some operators are required to be either
at the end of an expression or followed by a composition operator. So
far only the operators DW_OP_reg0-31 were allowed to be followed by
DW_OP_GNU_uninit instead, and particularly DW_OP_regx was not, which is
obviously inconsistent.
This patch allows DW_OP_GNU_uninit after all operators requiring a
composition, to simplify the code and make it more consistent. This
policy may be more permissive than necessary, but in the worst case just
leads to a DWARF location description resulting in an uninitialized
value instead of an error message.

* dwarf2expr.c (dwarf_expr_require_composition): Allow
DW_OP_GNU_uninit.
(execute_stack_op): Use dwarf_expr_require_composition instead of

arc: Remove annoying debug message
The logging message is called too often - once for each register when it's
value has to be evaluated. This floods the screen for commands like "info

think that removing it is preferable.

Simplify i386, amd64 and x32 expedite registers
Nowadays, there are a lot of duplication about
i386/{i386, amd64, x32}*-expedite in features/Makefile. However,
in features/Makefile, we have
echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
>> $(outdir)/$*.tmp
which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite. In x86 expedite registers, we
use the former now, but it will be much simpler if we use the latter.
This is what this patch does. This patch removes them, and defines
three generic expedite. Re-run 'make GDB=/path/build/gdb all' to
regenerate regformats/*.dat files, and they are not changed.

Fold arithmetic integer expressions
Commit b751e639 regressed arm linux kernel builds, that have an
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& ~ (((0x1 << 0xc) - 0x1))))
<= (0x1 << 0xc)), HYP init code too big or misaligned)
Due to some insanity in ld expression evaluation, the integer values
0x1 and 0xc above are treated as absolute addresses (ie. they have an
associated section, *ABS*, see exp_fold_tree_1 case etree_value) while
the expression (0x1 << 0xc) has a plain number result. The left hand
side of the inequality happens to evaluate to a "negative" .text
section relative value. Comparing a section relative value against an
absolute value works since the section relative value is first
converted to absolute. Comparing a section relative value against a
number just compares the offsets, which fails since the "negative"
offset is really a very large positive number.
This patch works around the problem by folding integer expressions, so
the assert again becomes
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& 0xfffffffffffff000))
<= 0x1000), HYP init code too big or misaligned)
* ldexp.c (exp_value_fold): New function.

Add test for user context selection sync
This patch adds a test to verify that events are sent properly to all
UIs when the user selection context (inferior, thread, frame) changes.
The goal of the C test file is to provide two threads that are stopped with the
same predictable backtrace (so that we can test frame switching). The barrier
helps us know when the child threads are started. Then, scheduler-locking is
used to bring each thread one by one to the position we expect them to be
during the test.

Emit inferior, thread and frame selection events to all UIs
With this patch, when an inferior, thread or frame is explicitly
selected by the user, notifications will appear on all CLI and MI UIs.
When a GDB console is integrated in a front-end, this allows the
front-end to follow a selection made by the user ont he CLI, and it
informs the user about selection changes made behind the scenes by the
front-end.
This patch addresses PR gdb/20487.
In order to communicate frame changes to the front-end, this patch adds
a new field to the =thread-selected event for the selected frame. The
idea is that since inferior/thread/frame can be seen as a composition,
it makes sense to send them together in the same event. The vision
would be to eventually send the inferior information as well, if we find
that it's needed, although the "=thread-selected" event would be
ill-named for that job.
Front-ends need to handle this new field if they want to follow the
frame selection changes that originate from the console. The format of
the frame attribute is the same as what is found in the *stopped events.
Here's a detailed example for each command and the events they generate:
thread
------
1. CLI command:
thread 1.3
MI event:
=thread-selected,id="3",frame={...}
2. MI command:
-thread-select 3
CLI event:
[Switching to thread 1.3 ...]
3. MI command (CLI-in-MI):
thread 1.3
MI event/reply:
&"thread 1.3\n"
~"#0 child_sub_function () ...
=thread-selected,id="3",frame={level="0",...}
^done
frame
-----
1. CLI command:
frame 1
MI event:
=thread-selected,id="3",frame={level="1",...}
2. MI command:
-stack-select-frame 1
CLI event:
#1 0x00000000004007f0 in child_function...
3. MI command (CLI-in-MI):
frame 1
MI event/reply:
&"frame 1\n"
~"#1 0x00000000004007f9 in ..."
=thread-selected,id="3",frame={level="1"...}
^done
inferior
--------
Inferior selection events only go from the console to MI, since there's
no way to select the inferior in pure MI.
1. CLI command:
inferior 2
MI event:
=thread-selected,id="3"
Note that if the user selects an inferior that is not started or exited,
the MI doesn't receive a notification. Since there is no threads to
select, the =thread-selected event does not apply...
2. MI command (CLI-in-MI):
inferior 2
MI event/reply:
&"inferior 2\n"
~"[Switching to inferior 2 ...]"
=thread-selected,id="4",frame={level="0"...}
^done
Internal implementation detail: this patch makes it possible to suppress
notifications caused by a CLI command, like what is done in mi-interp.c.
This means that it's now possible to use the
add_com_suppress_notification function to register a command with some
event suppressed. It is used to implement the select-frame command in
this patch.
The function command_notifies_uscc_observer was added to extract
the rather complicated logical expression from the if statement. It is
also now clearer what that logic does: if the command used by the user
already notifies the user_selected_context_changed observer, there is
not need to notify it again. It therefore protects again emitting the
event twice.
No regressions, tested on ubuntu 14.04 x86 with target boards unix and
native-extended-gdbserver.

PR 20627: Use resume_stop to stop lwp
Commit 049a8570 (Use target_continue{,_no_signal} instead of target_resume)
replaces the code stopping lwp with target_continue_no_signal in
target_stop_and_wait, like this,
- resume_info.thread = ptid;
- resume_info.kind = resume_stop;
- resume_info.sig = GDB_SIGNAL_0;
- (*the_target->resume) (&resume_info, 1);
+ target_continue_no_signal (ptid);
the replacement is not equivalent, and it causes PR 20627. This patch
is just to revert that change.

jit_breakpoint_re_set() is specific by trying to insert a breakpoint into the
main executable, not into a shared library. During attachment GDB thinks it
needs to use 'breakpoint always-inserted' from
breakpoints_should_be_inserted_now() as a newly attached thread is
'thread_info->executing' due to 'lwp_info->must_set_ptrace_flags' enabled and
the task not yet stopped. This did not happen before the 'bad commit' above
which adds tracking of such thread.
GDB then fails to insert the breakpoints to invalid address as PIE executable
gets properly relocated during later phase of attachment. One can see in the
backtraces below:
-> jit_breakpoint_re_set_internal()
later:
-> svr4_exec_displacement()
One can suppress the initial breakpoint_re_set() call as there will be another
breakpoint_re_set() done from the final post_create_inferior() call in
setup_inferior().
BTW additionally 'threads_executing' cache bool is somehow stale (somewhere is
missing update_threads_executing()). I was trying to deal with that in my
first/second attempt below but in my final third attempt (attached) I have
left it as it is.
First attempt trying not to falsely require 'breakpoint always-inserted':
https://people.redhat.com/jkratoch/rhbz1375553-fix1.patch
Reduced first attempt:
https://people.redhat.com/jkratoch/rhbz1375553-fix2.patch
The third attempt suppresses breakpoint insertion until PIE executable gets
relocated by svr4_exec_displacement(). Applied.

This is triggered by this check in display_debug_frames (dwarf.c):
case DW_CFA_restore:
if (opa >= (unsigned int) cie->ncols
|| opa >= (unsigned int) fc->ncols)
reg_prefix = bad_reg;
cie->ncols is number of registers referenced in the CIE which is 15 due
to r14 being given as return address column. So for the CFA_restore of
r15 a "bad register" is being printed while the same rule on r14 is ok.
The reason for this check is to prevent wild memory accesses when
reading input with corrupted register values while accessing the
col_type/col_offset arrays. However in that case r15 is a perfectly
valid register. It just happens not to be mentioned in the CIE. Hence
restoring the CIE rule for r15 should end up with the default rule which
is DW_CFA_undefined.
This probably wasn't observed on other platforms because they either do
not use CFA_restore (x86-64) or do not issue CFA_restore on registers
with a higher number than the return address column.

Small improvements to the remote protocol manual
I was reading the gdb RSP manual recently and I found a number of
small problems in the documentation. This patch attempts to improve
these areas. Specfically:
* The term "memory breakpoint" is used only in this section of the
manual, and there inconsistently. I found this term confusing --
initially I thought it might be a watchpoint. This patch changes it
to use the term "software breakpoint", which is used in the rest of
the manual.
* The z0 packet didn't document how "kind" was written. And, it had a
stray link to the architecture-specific protocol details node. This
patch moves this link to a better spot.
* The z1 patch didn't document that it accepts cmd_list.
* I couldn't find any text saying what response is given to a command
like vCont in non-stop mode. The answer is that OK is sent, and
then a stop reply is sent as a notification. This patch adds a note
about this.
* The "create" stop reply did not document that the "R" argument is
ignored.
* The "W", "X", and "w" packets did not document how the "AA" part is
formatted.
* The %Stop notification example said "%%Stop", but I think this is
incorrect.
2016-09-28 Tom Tromey <tom@tromey.com>
* gdb.texinfo (Packets) <z0>: Use "software breakpoint" rather
than "memory breakpoint". Further document "kind". Move
protocol-details link earlier.
<z1>: Document the cmd_list argument. Fix typo.
<g>: Remove incorrect sentence.
(Stop Reply Packets): Document "OK" response to requests when in
non-stop mode.
<swbreak>: Use "software breakpoint" rather than "memory
breakpoint".
<create>: Document that "R" is ignored.
<W, X, w>: Document formatting of "AA".
(Notification Packets): Use "%Stop", not "%%Stop".

PowerPC .gnu.attributes
This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker. I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings. This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

gdb: Replace operator new / operator new[]
If xmalloc fails allocating memory, usually because something tried a
huge allocation, like xmalloc(-1) or some such, GDB asks the user what
to do:
.../src/gdb/utils.c:1079: internal-error: virtual memory exhausted.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
If the user says "n", that throws a QUIT exception, which is caught by
one of the multiple CATCH(RETURN_MASK_ALL) blocks somewhere up the
stack.
The default implementations of operator new / operator new[] call
malloc directly, and on memory allocation failure throw
std::bad_alloc. Currently, if that happens, since nothing catches it,
the exception escapes out of main, and GDB aborts from unhandled
exception.
This patch replaces the default operator new variants with versions
that, just like xmalloc:
#1 - Raise an internal-error on memory allocation failure.
#2 - Throw a QUIT gdb_exception, so that the exact same CATCH blocks
continue handling memory allocation problems.
A minor complication of #2 is that operator new can _only_ throw
std::bad_alloc, or something that extends it:
void* operator new (std::size_t size) throw (std::bad_alloc);
That means that if we let a gdb QUIT exception escape from within
operator new, the C++ runtime aborts due to unexpected exception
thrown.
So to bridge the gap, this patch adds a new gdb_quit_bad_alloc
exception type that inherits both std::bad_alloc and gdb_exception,
and throws _that_.
If we decide that we should be catching memory allocation errors in
fewer places than all the places we currently catch them (everywhere
we use RETURN_MASK_ALL currently), then we could change operator new
to throw plain std::bad_alloc then. But I'm considering such a change
as separate matter from this one -- it'd make sense to do the same to
xmalloc at the same time, for instance.
Meanwhile, this allows using new/new[] instead of xmalloc/XNEW/etc.
without losing the "virtual memory exhausted" internal-error
safeguard.
Tested on x86_64 Fedora 23.

Close gdbserver in mi_gdb_exit
In commit 6423214f (testsuite: Don't use expect_background to reap
gdbserver), we override gdb_exit in lib/gdbserver-support.exp, so
that we can close gdbserver first. However, we don't close gdbserver
in mi_gdb_exit. This makes a problem in my aarch64 mulit-arch testing,
in which I run some mi tests, mi-watch.exp for example, in different
variations (aarch64 and arm),
Schedule of variations:
junor0-2
junor0-2-arm/-marm
junor0-2-arm/-mthumb
When the test is done in the first variation (aarch64), test case is
recompiled for arm, but GDBserver with aarch64 program is still
running. When the second variation is started, GDB loads arm program,
but GDBserver still loads aarch64 program because the old GDBserver
process is using it. We'll get,
47-target-select remote junor0-2:2350^M
&"warning: Selected architecture arm is not compatible with reported target architecture aarch64\n"^M
&"warning: Architecture rejected target-supplied description\n"
This patch fixes this problem by closing GDBserver in mi_gdb_exit.

arc: New Synopsys ARC port
ARC is a family of licensable processors developed by Synopsys.
This is an initial patch that doesn't yet support some of the features, that
are already available in Synopsys' fork of GDB, namely:
* longjmp support
* signal frame handling
* prologue analysis
* Linux targets support
* native Linux support
ARC cores are configurable and extensible, which means from debugger
perspective that some registers and debug capabilities are optional, therefore
it is up to the GDB stub to determine exact list of register available on
target and supply it to GDB via XML target descriptions. List of registers
that is known to GDB and is required is intentionally kept small to simplify
requirements to GDB stub and implementation of a GDB client.

PR gdb/20604 - fix "quit" when an invalid expression is used
This fixes PR gdb/20604. The bug here is that passing an invalid
expression to "quit" -- e.g., "quit()" -- causes gdb to enter a
non-functioning state.
The immediate problem is that quit_force resets the terminal before
evaluating the expression. However, it seemed to me that it doesn't
really make sense to pass the quit_force argument to kill_or_detach
(which passes it to to_detach), first because conflating the exit
status for "quit" and the signal to pass when detaching doesn't make
sense, and second because to_detach implementations generally only
accept a constant here, while "quit" accepts an expression. So, I
removed that.
As an aside, I think the "detach SIGNO" functionality is not
documented.
Built and regtested on x86-64 Fedora 24.

[AArch64] Add SVE condition codes
SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

[AArch64][SVE 28/32] Add SVE FP immediate operands
This patch adds support for the new SVE floating-point immediate
operands. One operand uses the same 8-bit encoding as base AArch64,
but in a different position. The others use a single bit to select
between two values.
One of the single-bit operands is a choice between 0 and 1, where 0
is not a valid 8-bit encoding. I think the cleanest way of handling
these single-bit immediates is therefore to use the IEEE float encoding
itself as the immediate value and select between the two possible values
when encoding and decoding.
As described in the covering note for the patch that added F_STRICT,
we get better error messages by accepting unsuffixed vector registers
and leaving the qualifier matching code to report an error. This means
that we carry on parsing the other operands, and so can try to parse FP
immediates for invalid instructions like:
fcpy z0, #2.5
In this case there is no suffix to tell us whether the immediate should
be treated as single or double precision. Again, we get better error
messages by picking one (arbitrary) immediate size and reporting an error
for the missing suffix later.

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch

This patch adds most of the new SVE addressing modes and associated

makes the changes easier to read.

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[AArch64][SVE 23/32] Add SVE pattern and prfop operands
The SVE instructions have two enumerated operands: one to select a
vector pattern and another to select a prefetch operation. The latter
is a cut-down version of the base AArch64 prefetch operation.
Both types of operand can also be specified as raw enum values such as #31.
Reserved values can only be specified this way.
If it hadn't been for the pattern operand, I would have been tempted
to use the existing parsing for prefetch operations and add extra
checks for SVE. However, since the patterns needed new enum parsing
code anyway, it seeemed cleaner to reuse it for the prefetches too.
Because of the small number of enum values, I don't think we'd gain
anything by using hash tables.

[AArch64][SVE 20/32] Add support for tied operands
SVE has some instructions in which the same register appears twice
in the assembly string, once as an input and once as an output.
This patch adds a general mechanism for that.
The patch needs to add new information to the instruction entries.
One option would have been to extend the flags field of the opcode
to 64 bits (since we already rely on 64-bit integers being available
on the host). However, the *_INSN macros mean that it's easy to add
new information as top-level fields without affecting the existing
table entries too much. Going for that option seemed to give slightly
neater code.

[AArch64][SVE 13/32] Add an F_STRICT flag
SVE predicate operands can appear in three forms:
1. unsuffixed: "Pn"
2. with a predication type: "Pn/[ZM]"
3. with a size suffix: "Pn.[BHSD]"
No variation is allowed: unsuffixed operands cannot have a (redundant)
suffix, and the suffixes can never be dropped. Unsuffixed Pn are used
in LDR and STR, but they are also used for Pg operands in cases where
the result is scalar and where there is therefore no choice to be made
between "merging" and "zeroing". This means that some Pg operands have
suffixes and others don't.
It would be possible to use context-sensitive parsing to handle
this difference. The tc-aarch64.c code would then raise an error
if the wrong kind of suffix is used for a particular instruction.
However, we get much more user-friendly error messages if we parse
all three forms for all SVE instructions and record the suffix as a
qualifier. The normal qualifier matching code can then report cases
where the wrong kind of suffix is used. This is a slight extension
of existing usage, which really only checks for the wrong choice of
suffix within a particular kind of suffix.
The only catch is a that a "NIL" entry in the qualifier list
specifically means "no suffix should be present" (case 1 above).
NIL isn't a wildcard here. It also means that an instruction that
requires all-NIL qualifiers can fail to match (because a suffix was
supplied when it shouldn't have been); this requires a slight change
to find_best_match.
This patch adds an F_STRICT flag to select this behaviour.
The flag will be set for all SVE instructions. The behaviour
for other instructions doesn't change.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

Previously:

This patch reports an invalid floating point constant unless the
operand is obviously a register.
The FPIMM8 handling is only relevant for SVE. Without it:

tested by the final patch.

[AArch64][SVE 08/32] Generalise aarch64_double_precision_fmovable
SVE has single-bit floating-point constants that don't really
have any relation to the AArch64 8-bit floating-point encoding.
(E.g. one of the constants selects between 0 and 1.) The easiest
way of representing them in the aarch64_opnd_info seemed to be
to use the IEEE float representation directly, rather than invent
some new scheme.
This patch paves the way for that by making the code that converts IEEE
doubles to IEEE floats accept any value in the range of an IEEE float,
not just zero and 8-bit floats. It leaves the range checking to the
caller (which already handles it).

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64][SVE 01/32] Remove parse_neon_operand_type
A false return from parse_neon_operand_type had an overloaded
meaning: either the parsing failed, or there was nothing to parse
(which isn't necessarily an error). The only caller, parse_typed_reg,
would therefore not consume the suffix if it was invalid but instead
(successfully) parse the register without a suffix. It would still
leave inst.parsing_error with an error about the invalid suffix.
It seems wrong for a successful parse to leave an error message,
so this patch makes parse_typed_reg return PARSE_FAIL instead.
The patch doesn't seem to make much difference in practice.
Most possible follow-on errors use set_first_error and so the
error about the suffix tended to win despite the successful parse.
gas/
* config/tc-aarch64.c (parse_neon_operand_type): Delete.
(parse_typed_reg): Call parse_neon_type_for_operand directly.

Keep reserved bits in CPSR on write
In patch https://sourceware.org/ml/gdb-patches/2016-04/msg00529.html
I cleared reserved bits when reading CPSR. It makes a problem that
these bits (zero) are written back to kernel through ptrace, and it
changes the state of the processor on some recent kernel, which is
unexpected.
In this patch, I keep these reserved bits when write CPSR back to
hardware.

Avoid -Wduplicated-cond warnings in gdb/python
I tried building gdb with -Wduplicated-cond. This patch fixes the
simpler issue that was found.
In Python 3, "int" and "long" are synonyms, so code like:
else if (PyLong_Check (obj))
...
else if (PyInt_Check (obj))
.... will trigger this warning. The fix is to conditionalize the
PyInt_Check branches on Python 2.
Tested by rebuilding, with both version of Python, on x86-64 Fedora 24.

ld: Extend documentation for EXCLUDE_FILE
There was a gap in the documentation of EXCLUDE_FILE that could cause
confusion to a user. When writing an input section specifier like this:
*(EXCLUDE_FILE (somefile.o) .text .text.*)
this could mean one of the following:
1. All '.text' and '.text.*' from all files except for 'somefile.o',
or
2. All '.text' from all files except 'somefile.o', and all '.text.*'
sections from all files.
It turns out that the second interpretation is correct, but the manual
does not make this clear (to me at least). Hopefully this patch makes
things clearer.

Pedro pointed out a regression happening on gdb.mi/mi-exec-run.exp,

gdb: Fix build breakage with GCC 4.1 and --disable-nls
Ref: https://sourceware.org/ml/gdb-patches/2016-09/msg00203.html
The std::{min,max} patch caused build failures when configuring GDB
with with --disable-nls and using GCC 4.1.
The reason is this bit in common/gdb_locale.h:
#ifdef ENABLE_NLS
...
#else
# define gettext(Msgid) (Msgid)
...
#endif
This causes problems if the <libintl.h> header is first included at
any point after "gdb_locale.h".
Specifically, the gettext&co declarations in libintl.h:
extern char *gettext (__const char *__msgid)
__THROW __attribute_format_arg__ (1);
end up broken after preprocessing:
extern char *(__const char *__msgid)
throw () __attribute__ ((__format_arg__ (1)));
After the std::min/std::max change to include <algorithm>, this now
happens with at least the GCC 4.1 copy of <algorithm>, which includes
<libintl.h> via <bits/stl_algobase.h>, <iosfwd>, and
<bits/c++locale.h>.
The fix is to simply remove the troublesome *gettext and *textdomain
macros, leaving only the _ and N_ ones.

2016-09-19 Pedro Alves <palves@redhat.com>
* common/gdb_locale.h [!ENABLE_NLS] (gettext, dgettext, dcgettext,

bfd: allow negative offsets to _GLOBAL_OFFSET_TABLE_ in elf64 SPARC
The code compiled with the -fpic model in SPARC uses 13-bit signed
immediate PC-relative loads to fetch entries from the GOT table. In
theory this would allow using a GOT table (.got section) containing up
to 1024 entries in elf32 or 512 entries in elf64.
However, in elf64 sparc GNU targets _GLOBAL_OFFSET_TABLE_ is always
placed at the beginning of the .got section, making it impossible to use
negative offsets. This limits the usage of -fpic to GOT tables
containing a maximum of 257 entries in elf64.
This patch activates an optimization that is already used in sparc-elf32
also in sparc-elf64, that sets _GLOBAL_OFFSET_TABLE_ to point 0x1000
into the .got section if the section size is bigger than 0x1000.

Consolidate target_mourn_inferior between GDB and gdbserver
This patch consolidates the API of target_mourn_inferior between GDB
and gdbserver, in my continuing efforts to make sharing the
fork_inferior function possible between both.
GDB's version of the function did not care about the inferior's ptid
being mourned, but gdbserver's needed to know this information. Since
it actually makes sense to pass the ptid as an argument, instead of
depending on a global value directly (which GDB's version did), I
decided to make the generic API to accept it. I then went on and
extended all calls being made on GDB to include a ptid argument (which
ended up being inferior_ptid most of the times, anyway), and now we
have a more sane interface.
On GDB's side, after talking to Pedro a bit about it, we decided that
just an assertion to make sure that the ptid being passed is equal to
inferior_ptid would be enough for now, on the GDB side. We can remove
the assertion and perform more operations later if we ever pass
anything different than inferior_ptid.
Regression tested on our BuildBot, everything OK.
I'd appreciate a special look at gdb/windows-nat.c's modification
because I wasn't really sure what to do there. It seemed to me that
maybe I should build a ptid out of the process information there, but
then I am almost sure the assertion on GDB's side would trigger.

The problem is that the std::min/std::max function templates use the

the compiler can't automatically deduce which template specialization
to pick from the arguments' types.
Fix that by specifying the specialization we want explicitly.

[ARC] Disassemble correctly extension instructions.
For each MAJOR-MINOR opcode tuple, we can have either a 3-operand, or
2-operand, or a single operand instruction format, depending on the
values present in i-field, and a-field.
The disassembler is reading the section containing the extension
instruction format and stores them in a table. Each table element
represents a linked list with encodings for a particular MAJOR-MINOR
tuple.
The current implementation checks only against the first element of
the list, hence, the issue.
This patch is walking the linked list until empty or finds an opcode
match. It also adds a test outlining the found problem.

testsuite: Disable ccache
There were always various problems with compatibility with ccache:
https://bugzilla.redhat.com/show_bug.cgi?id=488863
https://bugzilla.redhat.com/show_bug.cgi?id=759592
https://sourceware.org/ml/gdb-patches/2009-02/msg00397.html
IMO in a summary ccache finds more a benefit of faster compilation despite the
debug info is no longer exactly the same (as without ccache).
Although for example in this case ccache helped to find a real GDB bug:
https://sourceware.org/ml/gdb-patches/2015-01/msg00497.html
For the GDB testcases ccache has (IMO) no real performance advantage and it
just brings heisenbugs - false FAILs - from time to time:
Breakpoint 1, main () at gdb/testsuite/gdb.base/vdso-warning.c:21^M
21 return 0;^M
(gdb) PASS: gdb.base/vdso-warning.exp: run: startup
->
Breakpoint 1, main () at gdb/testsuite/gdb.base/hbreak-unmapped.c:21^M
21 return 0;^M
(gdb) FAIL: gdb.base/vdso-warning.exp: run: startup
So I find most safe and easy to just disable ccache for all testsuites.

gas: improve architecture mismatch diagnostics in sparc
Merely dumping the mnemonic name in "architecture mismatch" errors may
not provide enough information to determine what went wrong, as the same
mnemonic can be used for different variants of an instruction pertaining
to different architecture levels.
This little patch makes the assembler to include the instruction

gas: detect DCTI couples in sparc
Before SPARC V9 the effect of having a delayed branch instruction in the
delay slot of a conditional delayed branch was undefined.
In SPARC V9 DCTI couples are well defined.
However, starting with the UltraSPARC Architecture 2005, DCTI
couples (of all kind) are deprecated and should not be used, as they may
be slow or behave differently to what the programmer expects.

Fix for gdb.server/non-existing-program.exp test case
The test checks to make sure GDB exits cleanly if there is
no valid target binary. Currently, ppc and S390 fail on this
test. The function target_post_create_inferior () calls
linux_post_create_inferior () which calls the architecture
specific functions s390_arch_setup () and ppc_arch_setup ()
which make ptrace calls to access the architecture specific
registers. These ptrace calls fail because the process does
not exist causing GDB to exit on error.
This patch checks to see if the initial ptrace (PTRACE_TRACEME, ...)
call returned a status of TARGET_WAITKIND_EXITED indicating the
target has already exited. If the target has exited, then the
target_post_create_inferior () is not called since there is no
inferior to be setup. The test to see if the initial ptrace
call succeeded is done after the ptrace (PTRACE_TRACEME, ...)
call and the wait for the inferior process to stop, assuming
it exists, has occurred.
The patch has been tested on X86 64-bit, ppc64 and s390. If
fixes the test failures on ppc64 and s390. The test does not
fail on X86 64-bit. The patch does not introduce any additional
regression failures on any of these three platforms.

S/390: Add alternate processor names.
This patch adds alternate CPU names which adhere to the number of the
architecture document. So instead of having z196, zEC12, and z13 you
can use arch9, arch10, and arch11. The old cpu names stay valid and
should primarily be used.
The alternate names are supposed to improve compatibility with the IBM

Fix false FAIL on gdb.base/stap-probe.exp, due to ICF optimization
GCC 6's ICF optimization pass is making the declaration of 'm1' and
'm2', on gdb.base/stap-probe.c, to be unified. However, this leads to
only one instance of the probe 'two' being created, which causes a
failure on the testsuite (which expects a multi-location breakpoint to
be inserted on the probe).
This patch fixes this failure by declaring a dummy variable on 'm1',
and using it as an argument to m1's version of probe 'two'. Since we
do not care about the contents of the functions nor about the
arguments of each probe 'two', this is OK.

Pass HWCAP to ifunc resolver
On various GNU Elf architectures, including AArch64, ARM, s390/s390x,
ppc32/64, and sparc32/64, the dynamic loader passes HWCAP as a parameter
to each ifunc resolver. Currently there is an open glibc Bugzilla that
requests this to be generalized to all architectures:
https://sourceware.org/bugzilla/show_bug.cgi?id=19766
And various ifunc resolvers already rely on receiving HWCAP. Currently
GDB always calls an ifunc resolver without any arguments; thus the
resolver may receive garbage, and based on that, the resolver may decide
to return a function that is not suited for the given platform.
This patch always passes HWCAP to ifunc resolvers, even on systems where
the dynamic loader currently behaves otherwise. The rationale is
that (1) the dynamic loader may get adjusted on those systems as well in
the future; (2) passing an unused argument should not cause a problem
with existing resolvers; and (3) the logic is much simpler without such
a distinction.

(elf_gnu_ifunc_resolve_addr): Pass HWCAP to ifunc resolver.

* gdb.base/gnu-ifunc.exp: Add test to verify that the resolver
received HWCAP as its argument.

new-ui command: gdb internal errors if input is already pending
I noticed that if input is already pending on the new-ui TTY, gdb
internal-errors.
E.g., create /dev/pts/2, and type anything there (even just <return>
is sufficient).
Now start GDB creating a new UI on that TTY, while at the same time,
running a synchronous execution command. Something like:
$ gdb program -ex "new-ui console /dev/pts/2" -ex "start"
Back on /dev/pts/2, we get:
(gdb) .../src/gdb/event-top.c:360: internal-error: double prompt
A problem internal to GDB has been detected,
further debugging may prove unreliable.
While the main UI was waiting for "start" to finish, gdb kepts pumping
events, including the input fd of the extra console. The problem is
that stdin_event_handler doesn't restore the current UI back to what
it was, assuming that it's only ever called from the top level event
loop. However, in this case, it's being called from the nested event
loop from within maybe_wait_sync_command_done.
When finally the "start" command is done, we reach the code that
prints the prompt in the main UI, just before starting the main event
loop. Since now the current UI is pointing at the extra console (by
mistake), we find ourselves printing a double prompt on the extra
console. This is caught by the assertion that fails, as shown above.
Since other event handlers also don't restore the UI (e.g., signal
event handlers), I think it's better if whatever is pumping events to
take care to restore the UI, if it cares. That's what this patch
does. New test included.

Support 128-bit IEEE floating-point types on Intel and Power
Now that all the prerequisites are in place, this commit finally adds support
for handling the __float128 type on Intel and Power, by providing appropriate
platform-specific versions of the floatformat_for_type callback.
Since at this point we do not yet have any indication in the debug info to
distinguish different floating-point formats of the same length, we simply
use the type name as hint. Types named "__float128" get the IEEE format.
In addition to handling "__float128" itself, we also recognize "_Float128"
and (on Power) "_Float64x", as well as the complex versions of those.
(As pointed out by Joseph Myers, starting with GCC 7, __float128 is just
a typedef for _Float128 -- but it's good to handle this anyway.)
A new test case does some simple verification that the format is decoded
correctly, using both __float128 and "long double" to make sure using both
in the same file still works. Another new test verifies handling of the
_FloatN and _FloatNx types supported by GCC 7, as well as the complex
versions of those types.
Note that this still only supports basic format decoding and encoding.
We do not yet support the GNU extension 'g' suffix for __float128 constants.
In addition, since all *arithmetic* on floating-point values is still
performed in native host "long double" arithmetic, if that format is not
able to encode all target __float128 values, we may get incorrect results.
(To fix this would require implementing fully synthetic target floating-
point arithmetic along the lines of GCC's real.c, presumably using MPFR.)

Add gdbarch callback to provide formats for debug info float types
At this point, all TYPE_CODE_FLT types carry their floating-point format,
except for those creating from reading DWARF or stabs debug info. Those
will be addressed by this commit.
The main issue here is that we actually have to determine which floating-
point format to use. Currently, we only have the type length as input
to this decision. In the future, we may hopefully get --at least in
DWARF-- additional information to help disambiguate multiple different
formats of the same length. For now, we can still look at the type name
as a hint.
This decision logic is encapsulated in a gdbarch callback to allow
platform-specific overrides. The default implementation use the same
logic (compare type length against the various gdbarch_..._bit sizes)
that is currently implemented in floatformat_from_length.
With this commit, all platforms still use the default logic, so there
should be no actual change in behavior. A follow-on commit will add
support for __float128 on Intel and Power.
Once dwarf2read.c and stabsread.c make use of the new callback to
determine floating-point formats, we're now sure every TYPE_CODE_FLT
type will always carry its format. The commit therefore adds asserts
to verify_floatformat to ensure new code will continue to always
provide formats, and removes the code in floatformat_from_type that
used to handle types with a NULL TYPE_FLOATFORMAT.

Add missing format for built-in floating-point types
Many callers of init_float_type and arch_float_type still pass a NULL
floatformat. This commit changes those callers where the floatformat
that is supposed to be use is obvious. There are two categories where
this is the case:
- A number of built-in types are intended to match the platform ABI
floating-point types (i.e. types that use gdbarch_float_bit etc.).
Those places should use the platform ABI floating-point formats
defined via gdbarch_float_format etc.
- A number of language built-in types should simply use IEEE floating-
point formats, since the language actually defines that this is the
format that must be used to implement floating-point types for this
language. (This affects Java, Go, and Rust.) The same applies for
to the predefined "RS/6000" stabs floating-point built-in types.

Remove TYPE_NOSIGN "char" hack
init_type (and arch_integer_type) currently use a special hack to set the
TYPE_NOSIGN flag if the type name is exactly "char". This commit moves the
hack up to the callers of those routines.
The special case currently can hit only for types created from dwarf2read,
but read_base_type actually implements the "char" check itself, so it is
redundant to do it in init_type as well. (Note that stabsread.c and the
other type readers always pass NULL as name to init_type, so the special
case can never hit for those.)
A few other cases create pre-definded types with a hard-coded name of "char";
the commit simply moves setting the TYPE_NOSIGN flag to those places.
No functional change intended.

Unify init_type and arch_type interface and helpers
This adds a number of helper routines for creating objfile-owned types;
these correspond 1:1 to the already existing helper routines for creating
gdbarch-owned types, and are intended to be used instead of init_type.
A shared fragment of init_float_type and arch_float_type is extracted into
a separate subroutine verify_subroutine.
The commit also brings the interface of init_type in line with the one for
arch_type. In particular, this means removing the FLAGS argument; callers
now set the required flags directly. (Since most callers use the new
helper routines, very few callers actually need to set any additional
flags directly any more.)
Note that this means all the TYPE_FLAGS_... defined are no longer needed
anywhere; they will be removed by a follow-on commit.
All users of init_type are changed to use on of the new helpers where
possible. No functional change intended.

Fix PR ld/20545 - relaxation bugs in avr backend
Prior to the patch, addends for relocs were being adjusted even if
they went beyond an alignment boundary. This is wrong - to
preserve alignment constraints, the relaxation logic adds as many padding
bytes at the alignment boundary as was deleted, so addends beyond the
boundary should not be adjusted. avr-prop-7.s reproduces this
scenario.
Also, prior to this patch, the relaxation logic assumed that the addr
parameter pointed to the middle of the instruction to be deleted, and
that addr - count would therefore be the shrinked instruction's
address. This is true when actually shrinking instructions.
The alignment constraints handling logic also invokes the same logic
though, with addr as the starting offset of padding bytes and
with count as the number of bytes to be deleted. Calculating the
shrinked insn's address as addr - count is obviously wrong in this
case - that offset would point to count bytes before the last
non-padded byte. avr-prop-8.s reproduces this scenario.
To fix scenario 1, the patch adds an additional check to ensure reloc addends
aren't adjusted if they cross a shrink boundary. The shrink boundary
is either the section size or an alignment boundary. Addends pointing
at an alignment boundary don't need to be adjusted, as padding would
occur and keep the boundary the same. Addends pointing at section size
need to be adjusted though, as no padding occurs and the section size
itself would get decremented. The patch records whether padding
occured (did_pad) and uses that to detect and handle this condition.
To fix scenario 2, the patch adds an additional parameter
(delete_shrinks_insn) to elf32_avr_relax_delete_bytes to distinguish
instruction bytes deletion from padding bytes deletion. It then uses that to
correctly set shrinked_insn_address.

Fix PR19927: Avoid unwinder recursion if sniffer uses calls parse_and_eval
This fixes the problem exercised by Kevin's test at:
https://sourceware.org/ml/gdb-patches/2016-08/msg00216.html
This was originally exposed by the OpenJDK Python-based unwinder.
If an unwinder attempts to call parse_and_eval from within its
sniffing method, GDB's unwinding machinery enters infinite recursion.
However, parse_and_eval is a pretty reasonable thing to call, because
Python/Scheme-based unwinders will often need to read globals out of
inferior memory. The recursion happens because:
- get_current_frame() is called soon after the target stops.
- current_frame is NULL, and so we unwind it from the sentinel frame
(which is special and has level == -1).
- We reach get_prev_frame_if_no_cycle, which does cycle detection
based on frame id, and thus tries to compute the frame id of the new
frame.
- Frame id computation requires an unwinder, so we go through all
unwinder sniffers trying to see if one accepts the new frame (the
current frame).
- the unwinder's sniffer calls parse_and_eval().
- parse_and_eval depends on the selected frame/block, and if not set
yet, the selected frame is set to the current frame.
- get_current_frame () is called again. current_frame is still NULL,
so ...
- recurse forever.
In Kevin's test at:
https://sourceware.org/ml/gdb-patches/2016-08/msg00216.html
gdb doesn't recurse forever simply because the Python unwinder
contains code to detect and stop the recursion itself. However, GDB
goes downhill from here, e.g., by showing the sentinel frame as
current frame (note the -1):
Breakpoint 1, ccc (arg=<unavailable>) at py-recurse-unwind.c:23
23 }
(gdb) bt
#-1 ccc (arg=<unavailable>) at py-recurse-unwind.c:23
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
That "-1" frame level comes from this:
if (catch_exceptions (current_uiout, unwind_to_current_frame,
sentinel_frame, RETURN_MASK_ERROR) != 0)
{
/* Oops! Fake a current frame? Is this useful? It has a PC
of zero, for instance. */
current_frame = sentinel_frame;
}
which is bogus. It's never correct to set the current frame to the
sentinel frame. The only reason this has survived so long is that
getting here normally indicates something wrong has already happened
before and we fix that. And this case is no exception -- it doesn't
really matter how precisely we managed to get to that bogus code (it
has to do with the the stash), because anything after recursion
happens is going to be invalid.
So the fix is to avoid the recursion in the first place.
Observations:
#1 - The recursion happens because we try to do cycle detection from
within get_prev_frame_if_no_cycle. That requires computing the
frame id of the frame being unwound, and that itself requires
calling into the unwinders.
#2 - But, the first time we're unwinding from the sentinel frame,
when we reach get_prev_frame_if_no_cycle, there's no frame chain
at all yet:
- current_frame is NULL.
- the frame stash is empty.
Thus, there's really no need to do cycle detection the first time we
reach get_prev_frame_if_no_cycle, when building the current frame.
So we can break the recursion by making get_current_frame call a
simplified version of get_prev_frame_if_no_cycle that results in
setting the current_frame global _before_ computing the current
frame's id.
But, we can go a little bit further. As there's really no reason
anymore to compute the current frame's frame id immediately, we can
defer computing it to when some caller of get_current_frame might need
it. This was actually how the frame id was computed for all frames
before the stash-based cycle detection was added. So in a way, this
patch reintroduces the lazy frame id computation, but unlike before,
only for the case of the current frame, which turns out to be special.
This lazyness, however, requires adjusting
gdb.python/py-unwind-maint.exp, because that assumes unwinders are
immediately called as side effect of some commands. I didn't see a
need to preserve the behavior expected by that test (all it would take
is call get_frame_id inside get_current_frame), so I adjusted the
test.

Handle DW_OP_form_tls_address
Currently gdb supports DW_OP_GNU_push_tls_address, but not
DW_OP_form_tls_address. I think it would be better if the toolchain
as a whole moved to using the standard opcode, and the prerequisite to
this is getting gdb to recognize it.
GCC can sometimes emit DW_OP_form_tls_address for emultls targets. As
far as I know, nobody has ever tried this with gdb (since it wouldn't
work at all).
I don't think there's a major drawback to using a single opcode for
all targets, because computing the location of a thread-local is
already target specific.
This is PR gdb/11616.
I don't know how to write a test case for this; though it's worth
noting that there aren't explicit tests for DW_OP_GNU_push_tls_address
either -- and if I change GCC, these paths will be tested to the same
extent they are now.

Detect broken ptrace in gdb_skip_float_test
We recently found a ARM kernel ptrace bug
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-May/431962.html
Details can be found in the comment in gdb_skip_float_test. We can
skip floating point tests if the kernel bug is detected.
This patch adds more code in gdb_skip_float_test to detect the broken
ptrace on arm-linux. Such detection should be done at the beginning
of the test, because it starts a fresh GDB, so change the test cases
to invoke gdb_skip_float_test at the beginning of test, and use its
return value afterwards.
Since gdb_skip_float_test becomes a gdb_caching_proc, so it can't
have an argument, this patch also removes argument "msg", which isn't
useful.

Share target_wait prototype between GDB and gdbserver
This commit moves the target_wait prototype from the GDB-specific
target.h header to the common target/target.h header. Then, it
creates a compatible implementation of target_wait on gdbserver using
the_target->wait, and adjusts the (only) caller (mywait function).
Pretty straightforward, no regressions introduced.
gdb/gdbserver/ChangeLog:
2016-09-01 Sergio Durigan Junior <sergiodj@redhat.com>
* target.c (mywait): Call target_wait instead of
the_target->wait.
(target_wait): New function.

Use target_continue{,_no_signal} instead of target_resume
This commit implements a new function, target_continue, on top of the
target_resume function. Then, it replaces all calls to target_resume
by calls to target_continue or to the already existing
target_continue_no_signal.
This is one of the (many) necessary steps needed to consolidate the
target interface between GDB and gdbserver. In particular, I am
interested in the impact this change will have on the unification of
the fork_inferior function (which I have been working on).
Tested on the BuildBot, no regressions introduced.

Fix lwp_suspend/unsuspend imbalance in linux_wait_1
This patch fixes imbalanced lwp_suspend/unsuspend calls caused by the
premature choosing of another event for fairness.
select_event_lwp would switch the event before a call to
unsuspend_all_lwps, thus it would be called with the wrong event.
This caused an assertion failure: unsuspend LWP xx, suspended=-1 when
testing gdb.threads/non-stop-fair-events.exp with ARM range stepping in
GDBServer.
This patch moves the switch of event after the unsuspend/unstop calls.
No regressions, tested on ubuntu 14.04 ARMv7 and x86.
With gdbserver-native.

PowerPC VLE sh_flags and p_flags
ELF section sh_flags SHF_PPC_VLE was being set based on arch/mach,
which meant all code sections in an object file has the flag or all
lacked it. We can do better than that. Only those code sections
where VLE is enabled ought to have the flag, allowing an object file
to contain both VLE and non-VLE code.
Also, ELF header p_flags PF_PPC_VLE wasn't being set, and segments
were being split unnecessarily.

Dynamic TLS GOT entries would not be relocated.
Forgot to set should_relocate to TRUE in case of GOT and TLS relocations of
undefined symbols for shared libraries.
In dynamic libraries if symbol is not known the instruction relocation would

A test was created to detect similar future mistakes.

xtensa: Avoid designated inits, for C++ compliance
C++ does not officially support designators in initializer lists. Thus
some compilers may issue errors when encountering them. Modern versions
of GCC seem to allow them by default, as a GCC extension, even though
the GCC documentation explicitly states otherwise: "[...] This extension
is not implemented in GNU C++." But some older GCC versions (like
4.4.7) did indeed emit an error instead, like this:
.../gdb/xtensa-config.c:219: error: expected primary-expression before
â??.â?? token
This patch removes the only such instance I've seen when building with
'--enable-targets=all'.
gdb/ChangeLog:
* xtensa-tdep.h (XTENSA_GDBARCH_TDEP_INSTANTIATE): Replace
designated initializer list by plain initializer list, for C++
compliance.

powerpc ld configure
This fixes a few problems in the powerpc ld configury.
1) Using powerpc*le-* to test for powerpcle and powerpc64le would
incorrectly match a target triple like powerpc-apple-elf.
2) In the same vein, *64* could match 64 in the user supplied MANUF-OS
part of the target triple.
3) tooldir vars were missing, and some target aliases would result in
ridiculous values for those tdir_* vars given.
4) Since 2016-04-25, BE support was added automatically when asking
for an LE target. If that is a good idea, then so is adding LE
support when asking for BE.
* configure.tgt (powerpc*-*-linux* et al): Rewrite, adding LE
support for BE. First output all target endian configury
values, then opposite endian. Handle more tooldirs. Fix
bogus matches with strings in MANUF-OS part of target triple.

Sync proc_service definition with GLIBC
GLIBC BZ#20311 [1] proc_service.h install patch also remove 'const'
attributes from ps_get_thread_area and comment #15 discuss why to remove
the const attribute (basically since it a callback with the struct
ps_prochandle owned by the client it should be able to modify it if
it the case).
On default build this is not the issue and current g++ does not trigger
any issue with this mismatch declaration. However, on some bootstrap
build configuration where gdbserver is build with gcc instead this
triggers:
error: conflicting types for 'ps_get_thread_area'
This patch fixes it by syncing the declaration with GLIBC.

Test case to detect recursive unwinding in Python-based unwinders.
This test case verifies that GDB will not attempt to invoke a python
unwinder recursively.
At the moment, the behavior exhibited by GDB looks like this:
(gdb) source py-recurse-unwind.py
Python script imported
(gdb) b ccc
Breakpoint 1 at 0x4004bd: file py-recurse-unwind.c, line 23.
(gdb) run
Starting program: py-recurse-unwind
TestUnwinder: Recursion detected - returning early.
TestUnwinder: Recursion detected - returning early.
TestUnwinder: Recursion detected - returning early.
TestUnwinder: Recursion detected - returning early.
Breakpoint 1, ccc (arg=<unavailable>) at py-recurse-unwind.c:23
23 }
(gdb) bt
#-1 ccc (arg=<unavailable>) at py-recurse-unwind.c:23
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
[I've shortened pathnames for easier reading.]
The desired / expected behavior looks like this:
(gdb) source py-recurse-unwind.py
Python script imported
(gdb) b ccc
Breakpoint 1 at 0x4004bd: file py-recurse-unwind.c, line 23.
(gdb) run
Starting program: py-recurse-unwind
Breakpoint 1, ccc (arg=789) at py-recurse-unwind.c:23
23 }
(gdb) bt
#0 ccc (arg=789) at py-recurse-unwind.c:23
#1 0x00000000004004d5 in bbb (arg=456) at py-recurse-unwind.c:28
#2 0x00000000004004ed in aaa (arg=123) at py-recurse-unwind.c:34
#3 0x00000000004004fe in main () at py-recurse-unwind.c:40
Note that GDB's problems go well beyond the fact that it invokes the
unwinder recursively. In the process it messes up some internal state
(the frame stash) leading to display of (only) the sentinel frame in
the backtrace.

Allow resetting an empty inferior-tty
This patch allows the user to set the inferior-tty to "empty", in order
to come back to the default behaviour of using the same tty as gdb is
using.
This is already supported in MI (and tested in gdb.mi/mi-basics.exp).
I added a new test, set-inferior-tty.exp, where I test only the setting
and unsetting of the parameter. It would be nice to actually test that
the inferior output properly goes to the separate tty, but that will be
for another day.

* infcmd.c (set_inferior_io_terminal): Set inferior terminal to
NULL if terminal_name is an empty string.
(_initialize_infcmd): Make the argument of "set inferior-tty"
optional, mention it in the help doc.

Fix for gdb.base/pc-fp.exp.
It is my understanding that GDB used to require each architecture to
define a Frame Pointer (fp). However, this functionality was deprecated
some time ago so the call to setup the fp_reg was changed to deprecated
(set_gdbarch_deprecated_fp_regnum). It should have been removed from the
Power code.
That said, the code "set_gdbarch_deprecated_fp_regnum
(gdbarch, PPC_R0_REGNUM + 1);" sets up register r1 as the frame pointer.
Register r1 is no longer used to hold the frame pointer on Power. By
removing the fp definition for Power in GDB, it causes GDB to fall back
to the call get_frame_base_address (frame) which returns the correct value
depending on the specific senario but most of the time is the DWARF
canonical frame address.

Fix PR20494 - User input stops being echoed in CLI
This patch fixes a problem that problem triggers if you start an
inferior, e.g., with the "start" command, in a UI created with the
new-ui command, and then run a foreground execution command in the
main UI. Once the program stops for the latter command, typing in the
main UI no longer echoes back to the user.
The problem revolves around this:
- gdb_has_a_terminal computes its result lazily, on first call.
that is what saves gdb's initial main UI terminal state (the UI
associated with stdin):
our_terminal_info.ttystate = serial_get_tty_state (stdin_serial);
This is the state that target_terminal_ours() restores.
- In this scenario, the gdb_has_a_terminal function happens to be
first ever called from within the target_terminal_init call in
startup_inferior:
(top-gdb) bt
#0 gdb_has_a_terminal () at src/gdb/inflow.c:157
#1 0x000000000079db22 in child_terminal_init_with_pgrp () at src/gdb/inflow.c:217
[...]
#4 0x000000000065bacb in target_terminal_init () at src/gdb/target.c:456
#5 0x00000000004676d2 in startup_inferior () at src/gdb/fork-child.c:531
[...]
#7 0x000000000046b168 in linux_nat_create_inferior () at src/gdb/linux-nat.c:1112
[...]
#9 0x00000000005f20c9 in start_command (args=0x0, from_tty=1) at src/gdb/infcmd.c:657
If the command to start the inferior is issued on the main UI, then
readline will have deprepped the terminal when we reach the above, and
the problem doesn't appear.
If however the command is issued on a non-main UI, then when we reach
that gdb_has_a_terminal call, the main UI's terminal state is still
set to whatever readline has sets it to in rl_prep_terminal, which
happens to have echo disabled. Later, when the following synchronous
execution command finishes, we'll call target_terminal_ours to restore
gdb's the main UI's terminal settings, and that restores the terminal
state with echo disabled...
Conceptually, the fix is to move the gdb_has_a_terminal call earlier,
to someplace during GDB initialization, before readline/ncurses have
had a chance to change terminal settings. Turns out that
"set_initial_gdb_ttystate" is exactly such a place.
I say conceptually, because the fix actually inlines the
gdb_has_a_terminal part that saves the terminal state in
set_initial_gdb_ttystate and then simplifies gdb_has_a_terminal, since
there's no point in making gdb_has_a_terminal do lazy computation.

gdbserver_spawn "" rather than gdbserver_spawn ${binfile}
Hi,
I happen to see gdbserver is spawned like this in gdb.log,
spawn /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2346 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.s

erver/connect-stopped-target/connect-stopped-target /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/connect-stopped-target/connect-stopped-t
arget
as we can see, there are two instances of connect-stopped-target or
connect-stopped-target in the command line spawning gdbserver, but
none of these gets parameters from command line. In these two
tests, gdbserver is spawned via "gdbserver_spawn ${binfile}". However,
the argument of gdbserver_spawn is the argument passed the child
inferior, not the program itself.
# Start a gdbserver process running SERVER_EXEC, and connect GDB
# to it. CHILD_ARGS are passed to the inferior.
#
# Returns the target protocol and socket to connect to.
proc gdbserver_spawn { child_args } {
set target_exec [gdbserver_download_current_prog]
GDBserver gets the program via last_loaded_file, which is set by
gdb_file_cmd. In each test, we don't need to pass ${binfile}.

[AArch64] Add V8_2_INSN macro
For consistency with the previous two patches, this one
adds a macro for the two ARMv8.2 table entries. Both table
entries need a non-null aarch64_op field.
I haven't added macros for the RAS and STAT_PROFILE entries
since there's only one of each. The series isn't getting
rid of braced entries altogether, so I've only looked at
replacing things that occur more than once.

[AArch64] Add OP parameter to aarch64-tbl.h macros
Nick recently wrapped most of aarch64-tbl.h entries in macros
like CORE_INSN. These new macros assumed that the aarch64_op
"op" field of aarch64_opcode is 0 and that the new "verifier"
field is NULL.
However, there are a lot of CORE, SIMD and FP insns whose table
entries need a nonzero aarch64_op field, so these entries
continued to use a braced list instead of a macro. This makes
the table entries less consistent and means that there are still
quite a few braced entries that need to be updated when making
further changes to the aarch64_opcode structure.
I think the number of entries that need a nonzero aarch64_op
field is high enough to justify having an explicit aarch64_op
entry for all CORE, SIMD and FP entries. This patch adds
one and updates all existing uses of the macros. A following
patch makes more use of the macros.
I've followed existing practice by using 0 instead of OP_NIL
for empty aarch64_op fields. Empty fields are still the norm
and you need to know what the fields are when reading the table
anyway, so it was hard to justify an additional patch to replace
all 0 op fields with OP_NIL.

* aarch64-tbl.h (CORE_INSN, __FP_INSN, SIMD_INSN): Add OP parameter.

Fix PR gdb/20505 - Make vDSO detection work with core files
Loading a core dump that was either generated on a system running
pristine glibc master, or on a Fedora/RHEL system with LD_DEBUG=unused
set in the environment, solib-svr4.c:svr4_current_sos fails to filter
out the vDSO, resulting in:

...
The problem is that gdbarch_vsyscall_range does not support core
inferiors at all.
When live debugging, we're finding the vDSO's start address with
auxv/AT_SYSINFO_EHDR, and then we find the vDSO's size by look for the
corresponding mapping, by parsing /proc/PID/maps. When debugging a
core dump, we can also determine the starting address from
auxv/AT_SYSINFO_EHDR. However, we obviously can't read the core
mappings out of the host's /proc. But we can instead look for a
corresponding load segment in the core's bfd.

This test only collects the PC, and thus expects to only see one
register in the output of -trace-frame-collected. However, while on
the 64-bit ABI gdb only exposes 64-bit $pc/$rip (register 16 above),
on x32, GDB exposes 32-bit $eip as well, as a pseudo-register
(register 204 above). Thus, collecting $pc/$rip automatically always
collects $eip as well.

x32: gdb: Fix 'call' insn relocation with qRelocInsn
Running the fast tracepoints tests against x32 gdbserver exposes a
latent bug. E.g.,:
(gdb)
continue
Continuing.
Reading /media/sf_host-pedro/gdb/mygit/build-ubuntu-x32/gdb/testsuite/outputs/gdb.trace/change-loc/change-loc-2.sl from remote target...
Thread 1 "change-loc" received signal SIGSEGV, Segmentation fault.
func4 () at /home/pedro/gdb/src/gdb/testsuite/gdb.trace/change-loc.h:24
24 }
(gdb) FAIL: gdb.trace/change-loc.exp: 1 ftrace: continue to marker 2
The test sets a fast tracepoint on a shared library. On x32, shared
libraries end up loaded somewhere in the upper 2GB of the 4GB address
space x32 has access to. When gdbserver needs to copy an instruction
to execute it in the jump pad, it asks gdb to relocate/adjust it, with
the qRelocInsn packet. gdb converts "call" instructions into a "push
$<2GB-4GB addr> + jmp" sequence, however, the "pushq" instruction sign
extends its operand, so later when the called function returns, it
returns to an incorrectly sign-extended address. E.g.,
0xfffffffffabc0000 instead of 0xfabc0000, resulting in the
segmentation fault.
Fix this by converting calls at such addresses to "sub + mov + jmp"
sequences instead.

x32: Avoid unsigned long when installing fast tracepoint jump pads
We're casting through unsigned long to write a 64-bit immediate
operand of movabs (the comment said movl, but that was incorrect).
The problem is that unsigned long is 32-bit on x32, so we were writing
fewer bytes than necessary.
Fix this by using an 8 byte memcpy like in other similar places in the
function.

x32 Fast tracepoints: Customize jump pad address
MAP_32BIT is ignored on x32, meaning the jump pad can end up somewhere
between 2GB and 4GB, too far away from the executable for 5-byte
relative jumps (JMP rel32). So on x32, try explicitly placing the
jump pad near the middle of the available address space.

Fix for powerpc-power.exp gdb regression test for Power 9

Additionally the ppc test is missing the new Power 9 instructions as
well as a large number of older instructions. Additionally, some
instruction names have changed or been deleted. This patch
fixes the test failures and completely updates the test to make it
consistent with the supported Power 9 instructions listed in:

The patch fixes the record support of Hardware Transactional Memory
instructions on Power. It also solves a large number of unexpected failures
from gdb.reverse testcases sigall-precsave.exp and sigall-reverse.exp that
occur on distros which glibc uses HTM instructions.

sim: unify symbol table handling
The common sim tracing code already handles loading and tracking of
symbols from the target program so that it can show symbol info in
trace/disassembly calls. Once we touch up the trace code and add a
few API callbacks, ports don't need to do loading and searching of
symbol tables themselves anymore.

[GDB] Fix builds broken by proc-service changes.
GLIBC BZ#20311 introduced a change to install proc_service.h so that gdb
didn't have to use the version it embeds in gdb_proc_service.h. The
embedded version is guarded by HAVE_PROC_SERVICE_H and
gdb_proc_service.h has a number other of includes and definitions, all
of which are uncondional except for an include for gregset.h. This is
only included if HAVE_PROC_SERIVCE_H is not defined.
This causes a build failure when cross compiling gdb with the latest
glibc because type definitions in gregset are used independently of
HAVE_PROC_SERIVCE_H. In particular, they are used in gdb_proc_service.h
when PRFPREGSET_T_BROKEN is set.
The error messages on the failure are
----
binutils-gdb/gdb/gdb_proc_service.h:173:9: error: â??gdb_fpregset_tâ?? does

----
This patch moves the include for gregset.h to before the code guarded by
HAVE_PROC_SERIVCE_H, so that it is always included. This is enough to
fix the build.

The error is caused by the access to (*inp)[9] if 9 is out of its bounds.
However [1] looks odd to me, because if strncmp returns true (non-zero),
the following check "(*inp)[9] == ','" makes no sense any more. I
suspect it was a typo in the code we meant to "strncmp () == 0". Another
problem in the code above is that if *inp is "operator,", we first
increment *inp by 9, and then increment it by one again, which is wrong
to me. We should only increment *inp by 8 to skip "operator", and go
back to the loop header to decide where we stop.
gdb:

* location.c (explicit_location_lex_one): Compare the return
value of strncmp with zero. Don't check (*inp)[9]. Increment

The current machs.h mixes common enums with Blackfin-specific defines.
This causes us troubles with header inclusion order such that we can't
drop the old SIM_CPU typedef (which is duplicated in common code). By
splitting the two up, we can unwind this dependency chain, and drop the
old typedef. It also fixes building with older gcc versions.

[AArch64] Reject -0.0 as an 8-bit FP immediate
parse_aarch64_imm_float was accepting -0.0 even though that's not
a valid immediate for any instruction. The FPIMM0 caller rejected
it, but the FPIMM one would silently treat it as -2.0.
This patch rejects -0.0 and adds testcases to illegal.[sd].
Before the patch, the final error emitted for illegal.s was:
Error: cannot do 16-byte relocation
which was matched by:
[^:]*:569: Error: .*
The error was reported against the last line of the file rather than
the instruction that required the reloc. Adding more instructions
meant that the line number also changed.
Reporting against the wrong line isn't good from a QoI perspective
but isn't what I'm trying to fix here. Until it's fixed, I thought
it would be better to adjust the match to be against an end-of-file
comment rather than against whatever the last instruction happens to be.

at link time in a shared library.

Fix PR gdb/19187 (process record over a fork causes internal error)
Right after a fork is detected, we detach breakpoints from the child

inferior_ptid pointing at the child process, but leaves the breakpoint
marked inserted (in the parent).
The problem is that record-full.c always deletes all knowledge of the
breakpoint. Then when we later really delete the breakpoint from the
parent, we fail the assertion, since the breakpoint is unexpectedly
not found in the record-full.c breakpoint table.
The fix is simply to not forget about the breakpoint if we're
detaching it from a fork child.

MIPS/BFD: Actually produce short microMIPS LA25 stubs
For the case where a function which requires an LA25 stub is at the
beginning of a section we use a short sequence comprised of a LUI/ADDIU
instruction pair only and prepended to the associated function rather
than using a trailing jump to reach the function. This works by
checking for the offset into section of the function symbol being 0.
This is however never the case for microMIPS function symbols, which
have the ISA bit set. Consequently the short LA25 sequence is never
produced for microMIPS functions, like with the following example:
$ cat la25a.s
.abicalls
.global f1
.ent f1
f1:
.set noreorder
.cpload $25
.set reorder
.option pic0
jal f2
.option pic2
jr $31
.end f1
.global f2
.ent f2
f2:
jr $31

$ cat la25b.s

where `.pic.f1' could omit the trailing jump and the filler NOP and just
fall through to `f1'.
Correct the problem by masking out the ISA bit from microMIPS functions,

There is no need to do anything for MIPS16 functions, because if any
LA25 stub has been generated for such a function, then it is only
required for an associated call thunk only, which is regular MIPS code
and the address of which, with the ISA bit clear, is returned by
`mips_elf_get_la25_target'.
This problem has been there since the beginning of microMIPS support:

MIPS/BFD: Set the ISA bit in microMIPS LA25 stub references
Fix a linker regression introduced with commit 9d862524f6ae ("MIPS:
Verify the ISA mode and alignment of branch and jump targets") causing a
build failure in microMIPS glibc where the `zdump' tool fails to link:
.../timezone/zdump.o: In function `yeartot':
.../timezone/zdump.c:758:(.text+0x62): Jump to a non-instruction-aligned address
.../timezone/zdump.c:758:(.text+0x76): Jump to a non-instruction-aligned address
.../timezone/zdump.c:768:(.text+0x112): Jump to a non-instruction-aligned address
.../timezone/zdump.c:774:(.text+0x1b8): Jump to a non-instruction-aligned address
.../timezone/zdump.c:774:(.text+0x1cc): Jump to a non-instruction-aligned address
collect2: error: ld returned 1 exit status
make[2]: *** [.../timezone/zdump] Error 1
The cause of the failure is the stricter check introduced with the said
change for jump and branch targets tripping on the address of microMIPS
LA25 stubs. Despite being microMIPS code these stubs do not have the
ISA bit set throughout the relocation calculation process, because they
have their address set to the memory offset into the stub section they
are placed in.
The `mips_elf_la25_stub' structure does not carry ISA mode information,
but there is no need to extend it, because the ISA mode can be inferred
from the original symbol, which will have STO_MICROMIPS annotation, so
use that instead to set the ISA bit appropriately. Also only LA25 stubs
associated with microMIPS symbols need to have the ISA bit set, because
other LA25 stubs are made with regular MIPS code, even if associated
with a MIPS16 symbol (in which case they are needed by a call thunk only
rather than the MIPS16 function proper).

Support setting thread names (MS-Windows)
This is done by catching an exception number 0x406d1388 (it has no
documented name, though MSDN dubs it "MS_VC_EXCEPTION" in one code
example), which is thrown by the program. The exception record
contains an ID of a thread and a name to give it.
This requires rolling back some changes in handle_exception(), which
now again returns more than two distinct values. The new
HANDLE_EXCEPTION_IGNORED value means that gdb should just continue,
without returning the thread ID up the stack (which would result in
further handling of the exception, which is not what we want).

The fall-through in Target_sparc::Relocate::relocate for

up calling target_terminal_ours, which incorrectly always installs the
current UI's input_fd in the event loop... That is, code like this:
old_chain = make_cleanup_restore_target_terminal ();
target_terminal_ours_for_output ();
fprintf_unfiltered (mi->event_channel, "library-loaded");
...
do_cleanups (old_chain);
The fix is to move the add_file_handler/delete_file_handler calls out
of target_terminal_$foo, making these completely no-ops unless called
with the main UI as current UI.

Fix PR mi/20431 - Missing MI prompts after sync execution MI command (-exec-continue, etc.) errors
gdb 7.11 introduced an MI regression: a failing MI sync execution
command misses printing the MI prompt, and then all subsequent command
miss it too:
$ gdb-7.11.1 -i=mi
[...]
p 1
&"p 1\n"
~"$1 = 1"
~"\n"
^done
(gdb) <<< prompted ok
-exec-continue
^error,msg="The program is not being run." <<< missing prompt after this
print 1
&"print 1\n"
~"$2 = 1"
~"\n"
^done <<< missing prompt after this
gdb 7.10.1 behaved correctly, even with "set mi-async on":
-exec-continue
^error,msg="The program is not being run."
(gdb) <<< prompted ok
etc.

Merge async and sync code paths some more
[...]
The problem is that when an exception is thrown, we leave the prompt
state set to PROMPT_BLOCKED, and then mi_execute_command_input_handler
doesn't print the prompt. It used to work because before that patch,
we happened to skip disabling stdin if the current target didn't do
async (which it never does before execution).
I was surprised to find that this bug isn't caught by the testsuite,
so I made a thorough test that tests all combinations of pairs of:
- a failing synchronous execution command
- a failing non-execution command
- a non-failing command

Fix PR gdb/18653: gdb disturbs inferior's inherited signal dispositions
gdb's (or gdbserver's) own signal handling should not interfere with
the signal dispositions their spawned children inherit. However, it
currently does. For example, some paths in gdb cause SIGPIPE to be
set to SIG_IGN, and as consequence, the child starts with SIGPIPE to
set to SIG_IGN too, even though gdb was started with SIGPIPE set to
SIG_DFL.
This is because the exec family of functions does not reset the signal
disposition of signals that are set to SIG_IGN:
http://pubs.opengroup.org/onlinepubs/7908799/xsh/execve.html
Signals set to the default action (SIG_DFL) in the calling process
image are set to the default action in the new process
image. Signals set to be ignored (SIG_IGN) by the calling process
image are set to be ignored by the new process image. Signals set to
be caught by the calling process image are set to the default action
in the new process image (see <signal.h>).
And neither does it reset signal masks or flags.
In order to be transparent, when spawning new child processes to debug
(with "run", etc.), reset signal actions and mask back to what was
originally inherited from gdb/gdbserver's parent, just before execing
the target program to debug.

the process is a 32-bit arm one or 64-bit aarch64 one, and get the
right gdbarch. However, in the process of parsing auxv (in
inf_ptrace_auxv_parse), the size of int and data pointer of
target_gdbarch is used. If debug program exists (in most of cases),
target_gdbarch is already set according to the debug program, which
is arm in my case. Then, GDB can parse auxv successfully. However,
in gdb.base/attach-pie-noexec.exp, the debug program is removed,
target_gdbarch is aarch64 when GDB parse auxv, so GDB can't parse
it successfully.
Instead of using auxv, we check the return value of ptrace NT_ARM_VFP.
If the program is an arm process, NT_ARM_VFP is OK, otherwise, error
is returned.
Additionally, we only return tdesc_arm_with_neon for arm process,
because neon is mandatory on ARMv8.

gas: avoid spurious failures in non-ELF targets in the SPARC testsuite.
Many of the existing sparc tests fail in non-ELF targets (coff and
a.out) due to spurious differences in the expected results:
- Unlike ELF, a.out text sections are aligned to 2**3 and padded
accordingly. The padding instruction is a `nop' (01 00 00 00).
- Likewise, coff text sections are also aligned to 2**3 and padded
accordingly. However, the padding instruction in these targets is an
`illtrap 0' (00 00 00 00).
- Unlike ELF, a.out and coff binaries don't contain hardware
capabilities bits that could be used by BFD to determine the opcodes
architecture corresponding to the instructions encoded in the
objects (v9, v9a, v9b, v9c, etc). Consequently, in both a.out and
coff tests we would need to pass proper `-m sparc:vXXX' options when
invoking objdump before comparing results.
In order to fix these issues, the most obvious solution would be to have
three variants of .d files per impacted test. For example, for save.d
we would have: save-elf.d, save-aout.d and save-coff.d. Using the
`#source' directive, a single save.s file would provide the input for
all of them. However, this approach has the following problems:
- The #target and #notarget .d directives are very limited: they use
globs instead of regular expressions, and thus it is not possible (or
too messy) to use them to discriminate between elf, coff and a.out
sparc targets.
- It adds little or no value to have variants of all these tests for all
the target types, and it would be a burden to maintain them. Actually
the features tested in the spuriously failing tests (relatively modern
sparc instructions, registers and asis) are not really found in
running coff or a.out sparc systems.
This patch changes sparc.exp so it will run these tests only in
ELF-targets, using the more standard `is_elf_format' from
binutils-common.exp instead of the ad-hoc (and less convenient, as it
must be called before _every_ single elf-only test) sparc_elf_setup.
Incidentally, the patch also fixes the #name entry for save-args.d.

MIPS/GAS: Implement microMIPS branch/jump compaction
Convert microMIPS branches and jumps whose delay slot would be filled by
a generated NOP instruction to the corresponding compact form where one
exists, in a manner similar to MIPS16 JR->JRC and JALR->JALRC swap.
Do so even where the transformation switches from a 16-bit to a 32-bit
branch encoding for no benefit in code size reduction, as this is still
advantageous. This is because a branch/NOP pair takes 2 pipeline slots
or a 2-cycle completion latency except in superscalar implementations.
Whereas a compact branch may or may not stall on its target fetch, so it
will at most have a 2-cycle completion latency and may have only 1 even
in scalar implementations, and in superscalar implementations it is
expected to have no worse latency as a branch/NOP pair has. Also it
won't stall and therefore take the extra latency cycle in the not-taken
case.
Technically this is the same as MIPS16 compaction: for the qualifying
instruction encodings the APPEND_ADD_COMPACT machine code generation
method is selected where APPEND_ADD_WITH_NOP otherwise would and tells
the code generator in `append_insn' to convert the regular form of an
instruction to its corresponding compact form. For this the opcode is
tweaked as necessary and the microMIPS opcode table is scanned for the
matching updated instruction. A non-$0 `rt' operand to BEQ and BNE
instructions is moved to the `rs' operand field of BEQZC and BNEZC
encodings as required.
Unlike with MIPS16 compaction however we need to handle out-of-distance
branch relaxation as well. We do this by deferring the generation of
any delay-slot NOP required to relaxation made in `md_convert_frag', by
converting the APPEND_ADD_WITH_NOP machine code generation to APPEND_ADD
where a relaxed instruction is recorded. Relaxation then, depending on
actual code produced, chooses between either using a compact branch or
jump encoding and emitting the NOP outstanding if no compact encoding is
possible.
For code simplicity's sake the relaxation pass is retained even if the
principle of preferring a compact encoding to a 16-bit branch/NOP pair
means, in the absence of out-of-range branch relaxation, that a single
compact branch machine code instruction will eventually be produced from
a given assembly source instruction.

Fix PR server/20414 - x32 gdbserver always crashes inferior
Debugging an x32 process with an x32 gdbserver always results in:
(gdb) c
Continuing.
Program received signal SIGSEGV, Segmentation fault.
0xf7de9600 in _dl_debug_state () from target:/libx32/ld-linux-x32.so.2
(gdb)
Looking at the remote debug logs reveals the problem, here:
Packet received: T05swbreak:;06:a0d4ffff00000000;07:b8d3ffff00000000;10:0096def701000000;thread:p7d7a.7d7a;core:1;
^^^^^^^^^^^^^^^^
The underlined value is the expedited value of RIP (in little endian).
But notice that 01 in 0x01f7de9600, while gdb says the program stopped
at 0xf7de9600. 0x01ffffffff is over 32 bits, which indicates that
something wen't wrong somewhere in gdbserver.
The problem turns out to be in gdbserver's x86_get_pc / x86_set_pc
routines, where "unsigned long" is used assuming that it can fit a
64-bit value, while unsigned long is actually 32-bit on x32. The
result is that collect_register_by_name / supply_register_by_name end
up reading/writing random bytes off the stack.
Fix this by using explicit uint64_t instead of unsigned long.
For consistency, use uint32_t instead of unsigned int in the 32-bit
paths.

PR python/20190 - compute TLS symbol without a frame
PR python/20190 arose from an exception I noticed when trying to use
the Python unwinder for Spider Monkey in Firefox.
The problem is that the unwinder wants to examine the value of a
thread-local variable. However, sympy_value rejects this because
symbol_read_needs_frame returns true for a TLS variable.
This problem arose once before, though in a different context:
https://sourceware.org/bugzilla/show_bug.cgi?id=11803
At the time Pedro and Daniel pointed out a simpler way to fix that bug
(see links in 20190 if you are interested); but for this new bug I
couldn't think of a similar fix and ended up implementing Daniel's
other suggestion:
https://sourceware.org/ml/gdb-patches/2010-07/msg00393.html
That is, this patch makes it possible to detect whether a symbol needs
a specific frame, or whether it just needs the inferior to have
registers.
Built and regtested on x86-64 Fedora 24.

Fix PR gdb/20287 - x32 and "gdb_static_assert (sizeof (nat_siginfo_t) == sizeof (siginfo_t))"
Building an x32 gdb trips on a static assertion:
In file included from .../src/gdb/common/common-defs.h:71:0,
from .../src/gdb/nat/amd64-linux-siginfo.c:21:
.../src/gdb/common/gdb_assert.h:26:66: error: size of array â??never_defined_just_used_for_checkingâ?? is negative
extern int never_defined_just_used_for_checking[(expr) ? 1 : -1]
^
.../src/gdb/nat/amd64-linux-siginfo.c:113:1: note: in expansion of macro â??gdb_static_assertâ??
gdb_static_assert (sizeof (nat_siginfo_t) == sizeof (siginfo_t));
^
The problem is that the way nat_siginfo_t is defined, it can only
match the host's siginfo_t object when gdb is built as a 64-bit
program.
Several bits of nat_siginfo_t are off:
- nat_siginfo_t's _pad field's definition is:
int _pad[((128 / sizeof (int)) - 4)];
while /usr/include/bits/siginfo.h has:
# define __SI_MAX_SIZE 128
# if __WORDSIZE == 64
# define __SI_PAD_SIZE ((__SI_MAX_SIZE / sizeof (int)) - 4)
# else
# define __SI_PAD_SIZE ((__SI_MAX_SIZE / sizeof (int)) - 3)
# endif
and __WORDSIZE == 32 for x32. This is what causes the size of
nat_siginfo_t to be wrong and the assertion to fail.
- the nat_clock_t type is incorrect for 64-bit. We have this:
/* For native 64-bit, clock_t in _sigchld is 64bit aligned at 4 bytes. */
typedef long __attribute__ ((__aligned__ (4))) nat_clock_t;
however, /usr/include/bits/siginfo.h has:
# if defined __x86_64__ && __WORDSIZE == 32
/* si_utime and si_stime must be 4 byte aligned for x32 to match the
kernel. We align siginfo_t to 8 bytes so that si_utime and si_stime
are actually aligned to 8 bytes since their offsets are multiple of
8 bytes. */
typedef __clock_t __attribute__ ((__aligned__ (4))) __sigchld_clock_t;
# define __SI_ALIGNMENT __attribute__ ((__aligned__ (8)))
# else
typedef __clock_t __sigchld_clock_t;
# define __SI_ALIGNMENT
# endif
So we're currently forcing 4-byte alignment on clock_t, when it
should only be so for x32, not 64-bit.
The fix:
- Leaves nat_siginfo_t strictly for the 64-bit ABI.
- Adds a new typedef for the siginfo type that ptrace uses
(ptrace_siginfo_t). An x32 gdb always gets/sets an x32 siginfo_t
type with PTRACE_GETSIGINFO/PTRACE_SETSIGINFO.
- Uses this new ptrace_siginfo_t type instead of nat_siginfo_t as the
intermediate conversion type.

without setting the target triplet to i686-?-?.
Instead use is_amd64_regs_target to distinguish between x86_64 and ia32 ISA.

Handle correctly passing a bad interpreter name to new-ui
When a bad interpreter name is passed to new-ui, such as:
(gdb) new-ui bloop /dev/pts/10
A partially created UI is left in the UI list, with interp set to NULL.
Trying to do anything that will print on this UI (such as "start") will
cause a segmentation fault.
Changes in v2:
- Use with_test_prefix to namespace test procedures
- Give an explicit stable test name
- Add a "bad terminal path" test
- Remove useless runto_main
- Add missing intro comments
I did not factor out the pty spawn, as there is some magic involved I
don't quite understand. But it wouldn't bring that much anyway.

linux-procfs: Handle lowercase "t (tracing stop)" state
Since Linux 2.6.33, /proc/PID/status shows "t (tracing stop)", with
lowercase 't'. Because GDB is only expecting "T (tracing stop)", GDB
can incorrectly suppress errors in check_ptrace_stopped_lwp_gone:
1578 if (!check_ptrace_stopped_lwp_gone (lp))
1579 throw_exception (ex);

btrace: Resume recording after disconnect.
This patch allows gdbserver to continue recording after disconnect. On
reconnect, the recorded data is accessible to gdb as if no disconnect happened.
A possible application for this feature is remotely examine bugs that occur
at irregular intervals, where maintaining a gdb connection is inconvenient.

Fix ARMv8.1/v8.2 for hw watchpoint and breakpoint
The problem here is ARMv8.1 (and ARMv8.2) define a
different debug version than ARMv8 (7 and 8 respectively).

PR rust/20162 - fix gdb regressions caused by rust 1.10
PR rust/20162 started life as a reminder to test gdb with versions of
rust after 1.8; but now concerns some gdb regressions seen with rust
1.10 ("beta") and 1.11 ("nightly").
The failures turn out to be a discrepancy between how rustc emits
DWARF and how gdb interprets it. In particular, rustc will emit DWARF
like:
<2><bc>: Abbrev Number: 9 (DW_TAG_structure_type)
<bd> DW_AT_name : (indirect string, offset: 0x46a): HasMethods
<c1> DW_AT_byte_size : 4
...
<3><cc>: Abbrev Number: 11 (DW_TAG_subprogram)
...
<df> DW_AT_name : (indirect string, offset: 0x514f): new
gdb wants to see a separate top-level DW_TAG_subprogram that refers to
this one via DW_AT_specification; but rustc doesn't emit one. By my
reading of DWARF 4 5.5.7, this is ok, and gdb is incorrect here.
Fixing this involved a new case in scan_partial_symbols, and then a
further change in process_structure_scope to account for the fact
that, in Rust, such functions are not methods and should not be
attached to the structure type.
Next, it turns out that rust is emitting bad values for
DW_AT_linkage_name, e.g.:
<db> DW_AT_linkage_name: (indirect string, offset: 0x422): _ZN7methods8{{impl}}3newE
The the "{{impl}}" stuff is apparently some side effect of a change to
the compiler's internal representation. Oops!
This also had a simple fix -- disregard these mangled names.
With these changes, there are no regressions in the gdb Rust tests
with either 1.10 or 1.11. 1.9, the stable release, is still pretty
broken, but I think there's nothing much to do about that.
These changes are a bit hackish, but no worse, I think, than other
kinds of quirk handling already done in the DWARF parser. I have
reported all the rustc bugs upstream. I plan to remove these hacks
from gdb some suitable time after they have been fixed in released
versions of Rust.

FAIL: gdb.trace/mi-trace-frame-collected.exp: ctf: -trace-frame-collected
In ctf metadata, "num" in "tsv" is defined as unint32_t,

Support vCont s and S actions with software single step
GDBserver with software single step should be able to claim supporting
vCont s and S actions, so that GDB knows the remote target can do
single step. It doesn't matter to GDB that the single step in the
remote target is done via hardware or software.

Use reinsert_breakpoint for vCont;s
This patch is to teach GDBserver using software single step to handle
vCont;s. Simply speaking, if the thread's resume request is resume_step,
install reinsert breakpoint at the next pcs when GDBserver is about to
resume threads. These reinsert breakpoints of a thread are removed,
when GDBserver gets an event from that thread and reports it back to
GDB.

Enqueue signal even when resuming threads
Nowadays, we only enqueue signal when we leave thread pending in
linux_resume_one_thread. If lwp->resume->sig isn't zero (GDB wants
to resume with signal), we pass lwp->resume->sig to
linux_resume_one_lwp.
In order to reduce the difference between resuming thread with signal
and proceeding thread with signal, when we resume thread, we can
enqueue signal too, and proceed thread. The signal will be consumed in
linux_resume_one_lwp_throw from lwp->pending_signals.

Make reinsert_breakpoint thread specific
This patch makes reinsert_breakpoint thread specific, which means we
insert and remove reinsert_breakpoint breakpoints for a specific
thread. This motivation of this change is that I'll use
reinsert_breakpoint for vCont;s on software single step target, so that
GDBserver may insert one reinsert_breakpoint for one thread doing
step-over, and insert one reinsert_breakpoint for another thread doing
vCont;s. After the operation of one thread is finished, GDBserver must
remove reinsert_breakpoint for that thread only.
On the other hand, reinsert_breakpoint is used for step-over nowadays.
GDBserver inserts reinsert_breakpoint, and wait only from the thread
doing step-over. After the step-over is done, GDBserver removes the
reinsert_breakpoint. If there is still any threads need step-over, do
the same again until all threads are finished step-over. In other words,
reinsert_breakpoint is globally thread specific, but in an implicit way.
It is natural to make it explicitly thread specific.

Create sub classes of 'struct breakpoint'
Nowadays, there are three types of breakpoint in GDBserver,
- gdb breakpoints,
- reinsert breakpoints, used for software single step,
- other breakpoints, used for tracepoint,
but we only have one 'struct breakpoint' for all of them. Some fields
are only useful to one type of breakpoint. For example, cond_list
and command_list are only used by gdb breakpoints, while handler is
only used by other breakpoints.
This patch changes 'struct breakpoint' to a base class, which has fields
needed by all breakpoint types, also add three sub-classes to
'struct breakpoint' to these three types of breakpoints.

Pass breakpoint type in set_breakpoint_at
Nowadays, set_breakpoint_at creates breakpoint of type
other_breakpoint, but we also use set_breakpoint_at
in set_reinsert_breakpoint to create breakpoint, so that
we have to overwrite the breakpoint type like this,
bp = set_breakpoint_at (stop_at, NULL);
bp->type = reinsert_breakpoint;
which looks not very good. This patch changes set_breakpoint_at
to receive breakpoint type. Since set_breakpoint_at is
used in many places, I rename it to set_breakpoint_type_at, and wrap
it with set_breakpoint_at, and pass other_breakpoint. In this way,
we can call set_breakpoint_type_at with reinsert_breakpoint in
set_reinsert_breakpoint too, and code looks cleaner.

Without XML support in GDB, it can't parse xml sent by GDBserver, and has
to fall back to the oldest arch. However, GDBserver doesn't know this
(IMO, this is a defect in RSP), and still choose the right target
description to create regcache and 'g' packet. If the port only has
one target description or coincidentally two sides choose the same
target description, there is no such issue. Otherwise, GDB is broken
on read registers.
This patch is to skip gdbserver tests if XML is not support and the
target has multiple target descriptions.

Build gdb.opt/inline-*.exp tests at -O0, rely on __attribute__((always_inline))
A test recently added to gdb.opt/inline-cmds.exp fails for
arm-none-eabi targets because -O2 leads to instructions to be
reordered widely.
I guess it might have made sense years ago to enable optimization in
these tests, but I fail to see the need for that nowadays.
Using -O0 while relying on __attribute__((always_inline)), which is
already used in the tests [1] [2], avoids this sort of trouble, while
still exercising the inlining-related use cases that are the focus of
these tests.
I think that nowadays we can safely assume that all compilers we care
about support __attribute__((always_inline)) or similar.
[1] - Except one spot that missed it.
[2] - Note that the .exp files make sure the frames that should have
been inlined are indeed inlined, with "info frame".

MIPS: Verify the ISA mode and alignment of branch and jump targets
Verify that the ISA mode of branch targets is the same as the referring
relocation, so that an attempt to produce a branch between instructions
encoded in different ISA modes each causes an error rather than silently
producing non-functional code. Make sure that no symbol or addend bits
are silently truncated: terminate with an error if the relocation value
calculated cannot be encoded in the relocatable field of a branch; for
REL targets also applying to any intermediate addend.
Also make jump target's alignment verification consistent with that for
branches.
This change will require an update to some obscure handcoded assembly
sources which make branches to labels placed at data objects, however
for microMIPS code only. These labels will have to be updated with the
`.insn' directive for containing code to assemble and link successfully.
Such code is broken as any such labels have always been required by the
microMIPS architecture specification[1][2] to be annotated this way for
correct interpretation, and with our old code missing `.insn' directives
caused labels to present different semantics depending on whether they
were referred with branch (ISA bit ignored) or other relocations (ISA
bit respected).
Enforcing these checks however will ensure errors in building software,
like mixed regular MIPS and microMIPS code links with branches between,
will be diagnosed at the build time rather than causing odd run-time
errors such as intermittent crashes. It will also let cross-mode BAL
instructions be converted to JALX instructions, with a separate change.

It can be initialized with values greater than 0x80000000, which don't fit in a
signed int. Further it appears to be used as a set of bit flags where unsigned
int is more typical.

ld: Restore file offset after a plugin fails to claim a file
When using the plugin interface to claim an input file the claim method
from (possible) many plugins can be called on an input file. If these
claim methods read content from the input file then the file offset
stored in the underlying file descriptor will change.
As we share a file descriptor between the plugin interface (created with
dup in ld/plugin.c:plugin_object_p) and the input bfd object, then any
changes to the file offset in the file descriptor will effect the bfd
object. Also, as the changes to the file offset did not originate from
calls through the bfd interface, but instead came from the plugin
directly, then the bfd will not be aware that the file offset has
changed. This is a problem as the bfd library caches the file offset.
If the plugin decides not to claim an input file then, currently, we
leave the bfd in a state where the actual file offset is out of sync
with the cached file offset.
This problem came to light after a recent commit
7d0b9ebc1e0079271a7c7737b53bc026525eab64 (Don't include libbfd.h outside
of bfd, part 6) however, I don't believe that commit actual introduces
the bug, it just exposed the existing issue.
This commit solves the problem by backing up and restoring the file
offset for the file descriptor of the input file. The restore is only
done if the plugin does not claim the input file, as it is in this case
that the bfd library might be used again to try and identify the
unclaimed file.
ld/ChangeLog:
* plugin.c (plugin_call_claim_file): Restore the file offset after
an unsuccessful attempt to claim a file.
* testplug.c (bytes_to_read_before_claim): New global.
(record_read_length): New function, sets new global
bytes_to_read_before_claim.
(parse_option): Handle 'read:<NUMBER>' option.
(onclaim_file): Read file content before checking for claim.
* testsuite/ld-plugin/plugin-30.d: New file.
* testsuite/ld-plugin/plugin.exp: Add new test.

GDB testsuite: Escape paths used in regular expressions
This patch fixes problems with a few GDB testsuites when executing in a
path that contains special characters (e.g. "++"). When such paths are
used as a regular expression, the regular expression parser will choke
and cause the tests to fail. This patch uses string_to_regexp to
escape strings that will be used as regular expressions, in order to
sanitize path names used in expect scripts.

MIPS/GAS: Don't convert PC-relative REL relocs against absolute symbols
Don't convert PC-relative REL relocations against absolute symbols to
section-relative references and retain the original symbol reference
instead. Offsets into the absolute section may overflow the limited
range of their in-place addend field, causing an assembly error, e.g.:
$ cat test.s
.text
.globl foo
.ent foo
foo:
b bar
.end foo
.set bar, 0x12345678
$ as -EB -32 -o test.o test.s
test.s: Assembler messages:
test.s:3: Error: relocation overflow
$
With the original reference retained the source can now be assembled and
linked successfully:
$ as -EB -32 -o test.o test.s
$ objdump -dr test.o
test.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <foo>:
0: 1000ffff b 0 <foo>
0: R_MIPS_PC16 bar
4: 00000000 nop
...
$ ld -melf32btsmip -Ttext 0x12340000 -e foo -o test test.o
$ objdump -dr test
test: file format elf32-tradbigmips
Disassembly of section .text:
12340000 <foo>:
12340000: 1000159d b 12345678 <bar>
12340004: 00000000 nop
...
$
For simplicity always retain the original symbol reference, even if it
would indeed fit.
Making TC_FORCE_RELOCATION_ABS separate from TC_FORCE_RELOCATION causes
R_MICROMIPS_PC7_S1, R_MICROMIPS_PC10_S1 and R_MICROMIPS_PC16_S1 branch
relocations against absolute symbols to be converted on RELA targets to
section-relative references. This is an intended effect of this change.
Absolute symbols carry no ISA annotation in their `st_other' field and
their value is not going to change with linker relaxation, so it is safe
to discard the original reference and keep the calculated final symbol
value only in the relocation's addend.
Similarly R6 R_MIPS_PCHI16 and R_MIPS_PCLO16 relocations referring
absolute symbols can be safely converted even on REL targets, as there
the in-place addend of these relocations covers the entire 32-bit
address space so it can hold the calculated final symbol value, and
likewise the value referred won't be affected by any linker relaxation.
Add a set of suitable test cases and enable REL linker tests which now
work and were previously used as dump patterns for RELA tests only.

MIPS/GAS: Keep the ISA bit in the addend of branch relocations
Correct a problem with the ISA bit being stripped from the addend of
compressed branch relocations, affecting RELA targets. It has been
there since microMIPS support has been added, with:

<https://sourceware.org/ml/binutils/2011-07/msg00198.html>, ("MIPS:
microMIPS ASE support") and R_MICROMIPS_PC7_S1, R_MICROMIPS_PC10_S1 and
R_MICROMIPS_PC16_S1 relocations originally affected, and the
R_MIPS16_PC16_S1 relocation recently added with commit c9775dde3277
("MIPS16: Add R_MIPS16_PC16_S1 branch relocation support") actually
triggering a linker error, due to its heightened processing strictness
level:
$ cat test.s
.text
.set mips16
foo:
b bar
.set bar, 0x1235
.align 4, 0
$ as -EB -n32 -o test.o test.s
$ objdump -dr test.o
test.o: file format elf32-ntradbigmips
Disassembly of section .text:
00000000 <foo>:
0: f000 1000 b 4 <foo+0x4>
0: R_MIPS16_PC16_S1 *ABS*+0x1230
...
$ ld -melf32btsmipn32 -Ttext 0 -e 0 -o test test.o
test.o: In function `foo':
(.text+0x0): Branch to a non-instruction-aligned address
$
This is because the ISA bit of the branch target does not match the ISA
bit of the referring branch, hardwired to 1 of course.
Retain the ISA bit then, so that the linker knows this is really MIPS16
code referred:
$ objdump -dr fixed.o
fixed.o: file format elf32-ntradbigmips
Disassembly of section .text:
00000000 <foo>:
0: f000 1000 b 4 <foo+0x4>
0: R_MIPS16_PC16_S1 *ABS*+0x1231
...
$ ld -melf32btsmipn32 -Ttext 0 -e 0 -o fixed fixed.o
$
Add a set of MIPS16 tests to cover the relevant cases, excluding linker
tests though which would overflow the in-place addend on REL targets and
use them as dump patterns for RELA targets only.

BFD: Let targets handle relocations against absolute symbols
Fix a generic BFD issue with relocations against absolute symbols, which
are installed without using any individual relocation handler provided
by the backend. This causes any absolute section's addend to be lost on
REL targets such as o32 MIPS, and also relocation-specific calculation
adjustments are not made.
As an example assembling this program:
$ cat test.s
.text
foo:
b bar
b baz
.set bar, 0x1234
$ as -EB -32 -o test-o32.o test.s
$ as -EB -n32 -o test-n32.o test.s
produces this binary code:
$ objdump -dr test-o32.o test-n32.o
test-o32.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <foo>:
0: 10000000 b 4 <foo+0x4>
0: R_MIPS_PC16 *ABS*
4: 00000000 nop
8: 1000ffff b 8 <foo+0x8>
8: R_MIPS_PC16 baz
c: 00000000 nop
test-n32.o: file format elf32-ntradbigmips
Disassembly of section .text:
00000000 <foo>:
0: 10000000 b 4 <foo+0x4>
0: R_MIPS_PC16 *ABS*+0x1230
4: 00000000 nop
8: 10000000 b c <foo+0xc>
8: R_MIPS_PC16 baz-0x4
c: 00000000 nop
$
where it is clearly visible in `test-o32.o', which uses REL relocations,
that the absolute section's addend equivalent to the value of `bar' -- a
reference to which cannot be fully resolved at the assembly time,
because the reference is PC-relative -- has been lost, as has been the
relocation-specific adjustment of -4, required to take into account the
PC+4-relative calculation made by hardware with branches and seen in the
external symbol reference to `baz' as the `ffff' addend encoded in the
instruction word. In `test-n32.o', which uses RELA relocations, the
absolute section's addend has been correctly retained.
Give precedence then in `bfd_perform_relocation' and
`bfd_install_relocation' to any individual relocation handler the
backend selected may have provided, while still resorting to the generic
calculation otherwise. This retains the semantics which we've had since
forever or before the beginning of our repository history, and is at the
very least compatible with `bfd_elf_generic_reloc' being used as the
handler.
Retain the `bfd_is_und_section' check unchanged at the beginning of
`bfd_perform_relocation' since this does not affect the semantics of the
function. The check returns the same `bfd_reloc_undefined' code the
check for a null `howto' does, so swapping the two does not matter.
Also the check is is mutually exclusive with the `bfd_is_abs_section'
check, since a section cannot be absolute and undefined both at once, so
swapping the two does not matter either.
With this change applied the program quoted above now has the in-place
addend correctly calculated and installed in the field being relocated:
$ objdump -dr fixed-o32.o
fixed-o32.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <foo>:
0: 1000048c b 1234 <bar>
0: R_MIPS_PC16 *ABS*
4: 00000000 nop
8: 1000ffff b 8 <foo+0x8>
8: R_MIPS_PC16 baz
c: 00000000 nop
$
Add a set of MIPS tests to cover the relevant cases, including absolute
symbols with addends, and verifying that PC-relative relocations against
symbols concerned resolve to the same value in the final link regardless
of whether the REL or the RELA relocation form is used. Exclude linker
tests though which would overflow the in-place addend on REL targets and
use them as dump patterns for RELA targets only.

objcopy/strip: Add option --remove-relocations=SECTIONPATTERN
The objcopy and strip tools make use of the bfd library to manipulate
the state of the input file (to produce an output file). Within the
input file (for ELF at least), relocations are held within a section,
and so, if the user wanted to remove the relocations, but keep the
section to which the relocations would have been applied, it is tempting
to think that specifying the name of a relocation section to objcopy's
--remove-section option might do what you want, for example:
objcopy --remove-section=.rela.text input.elf output.elf
However, this does not work. The reason is that when the input file is
loaded, relocations are not managed as sections, but are, instead,
loaded as data associated with the section to which the relocations
would be applied. In our example above the relocations in '.rela.text'
are held as data on the section '.text' once 'input.elf' is loaded.
One task that objcopy and strip do is copy the relocations from the
input file to the output file if the section is also being copied from
the input file to the output file.
This commit adds a new command line option for objcopy and strip,
--remove-relocations, which can be used to remove the relocations, while
keeping the section that the relocations would have been applied to, for
example:
objcopy --remove-relocations=.text input.elf output.elf
in this case the section '.text' will appear in both 'input.elf' and
'output.elf', but any relocations in 'input.elf' that apply to '.text'
will not be present in 'output.elf'.
I have also added a special case to the handling of --remove-section
that spots if a user tries to remove a relocation section (currently
this is done by spotting the '.rela.' or '.rel.' prefix) and forwards
the request to --remove-relocations.
As with --remove-section and --only-section the --remove-relocations
option supports the '!' prefix on the section-patterns it takes to allow
for sections to be specifically not matched.
There are tests for all the new functionality.

objcopy/strip: Allow section patterns starting with '!'.
For symbol matching, prefixing a pattern with '!' will indicate a
non-matching pattern, however, this is not the case for section
patterns. As a result it is not possible to say "apply this action to
all sections except ...".
With this commit the objcopy and strip tools now support '!' prefix for
section patterns, so we can say:
objcopy --remove-section="*" --remove-section="!.text*"
Which will remove all sections, except those matching the pattern
'.text*'.

PR python/15620, PR python/18620 - breakpoint events in Python
This patch adds some breakpoint events to Python. In particular,
there is a creation event that is emitted when a breakpoint is
created; a modification event that is emitted when a breakpoint
changes somehow; and a deletion event that is emitted when a
breakpoint is deleted.
In this patch, the event's payload is the breakpoint itself. I
considered making a new event type to hold the breakpoint, but I
didn't see a need. Still, I thought I would mention this as a spot
where some other choice is possible.

use user_breakpoint_p in python code
I noticed that bppy_get_visibility and gdbpy_breakpoint_created
implemented their own visibility checks, but subtly different from
user_breakpoint_p. I think the latter is more correct, and so changed
the Python code to use it.
I suspect there isn't a decent way to test this, so no new test.

Rearrange Python breakpoint node in documentation
I noticed that the Python breakpoint documentation was ordered a bit
oddly. It documented the constructor; then the stop method; then the
watchpoint constants (used for the constructor); then various other
methods and attributes; then the other constants used by the
constructor; and then finally some more methods and attributes.
This patch rearranges the node a little to move the constants to just
after the constructor and before the other methods and attributes.

Fix PR cli/18053
PR cli/18053 concerns a couple of minor bugs in the JIT debuginfo
support. First, jit-reader-load should use filename completion and
support tilde expansion. Second, the help for jit-reader-unload is
incorrect. While working on this I also realized that
jit-reader-unload should use the no-op completer, so I've included
that as well.
Built and regtested on x86-64 Fedora 23. A completer test for
jit-reader-load is included, but not a tilde-expansion test, as I
couldn't think of a reliable way to test that.

MIPS/opcodes: Address issues with NAL disassembly
Address issues with the disassembly of the NAL assembly idiom and R6
instruction introduced with commit 7361da2c952e ("Add support for MIPS
R6.") and then further tweaked with commit b9121b573e2e ("Add in a JALRC
alias and fix the NAL instruction."). As from R6 this instruction has
replaced the encoding of `bltzal $0, . + 4' as the solely supported form
of the former BLTZAL instruction for the regular MIPS ISA.
The instruction is marked as an alias only in our regular MIPS opcode
table, making it fail to disassemble in R6 code if the `no-aliases'
machine option has been passed to `objdump':
$ cat test.s
.text
foo:
nal
$ as -mips64r6 -o test.o test.s
$ objdump -dr --prefix-addresses --show-raw-insn -M no-aliases test.o
nal.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <foo> 04100000 0x4100000
...
$
This is because the `bltzal' entry has been marked as pre-R6 only in the
opcode table and there is no other opcode pattern to match.
Additionally the changes referred made NAL replace the equivalent
`bltzal $0, . + 4' instruction in disassembly, unless the `no-aliases'
machine option has been used, in legacy code. Seeing NAL, especially in
its updated form lacking the branch target argument, in the disassembly
of such code may be confusing to people. This is because unlike with
EHB only used in R2 and newer code -- the machine encoding of which we
anyway always disassemble to its corresponding current architecture's
mnemonic rather than its legacy meaning of `sll $0, $0, 3' -- BLTZAL has
been indeed used in legacy code. Even though `bltzal $0, . + 8' and its
machine code encoding (0x04100001) -- which is not equivalent to NAL and
still disassembles as BLTZAL -- has been the predominant form as opposed
to NAL's `bltzal $0, . + 4' (0x04100000), it makes sense to always keep
the old form in disassembly, while still accepting `nal' in assembly.
Remove the alias marking then from the the `nal' instruction pattern,
making it always match for R6 code, even with the `no-aliases' option.
And move the entry beyond the `bltzal' entry, making the latter one take
precedence for legacy binary code, while letting the former still match
any `nal' mnemonic in source code assembled for a legacy target.
Add a suitable test case to the GAS test suite. While the change
affects the disassembler more than the assembler, so placing the test
case in the binutils test suite might be more appropriate, the intent is
also to verify that `nal' is still accepted by GAS for legacy targets,
plus we have test infrastructure available in the GAS test suite for
automatic multiple ISA level testing, which we lack from the binutils
framework.

PR python/19293 - invalidate frame cache when unwinders change
PR python/19293 notes that when a Python unwinder is disabled, the
frame cache is not invalidated. This means that disabling an unwinder
doesn't have any immediate effect -- but in my experience it's often
the case that I want to enable or disable an unwinder in order to see
what happens.
This patch adds a new gdb.invalidate_cached_frames function and
arranges for the relevant bits of library code to call it. I've only
partially documented this function, considering a warning sufficient
without going into all the reasons ordinary code should not call it.
The name of the new function was taken from a comment in frame.h next
to reinit_frame_cache.
No new test as I think the updates to the existing test are sufficient
to show that the code is working as intended.
