Change language name in LC_IDENTIFICATION of bn_BD and bn_IN from “Bengali” to “Bangla”
[BZ #14925]
* locales/bn_BD (LC_IDENTIFICATION): Change language name in
“title” and “language” from Bengali to Bangla.

conformtest: Disable si_value expectation for XPG42.
This patch corrects the conform/ expectations for sys/wait.h not to
expect si_value for XPG4.2.
Tested for x86_64.

manual: Rewrite the section on widths of integer types.
The manual contradicted itself by saying the number of bits in an
integer type needed to be computed, and then listing a number of
macros that later standards provided for exactly that. The entire
section has been reworked to provide those macros first, while
preserving the documentation of CHAR_BIT and the associated examples
within that context.
* manual/lang.texi
(Computing the Width of an Integer Data Type): Rename section
to "Width of an Integer Type". Remove inaccurate statement
regarding lack of C language facilities for determining width
of integer types, and reorder content to improve flow and
context of discussion.
manual: Update @standards for [__]va_copy.
The ISO version in which va_copy was introduced is made explicit, and
__va_copy is given @standards. The description is updated to be more
clear about the origins of each macro, and the reader is informed
these macros are now provided by the compiler (information previously
embedded in a Texinfo @comment).
* lang.texi (va_copy): Change standard from ISO to C99.
(__va_copy): Add standard and header annotation.
Update description for clarity of origins and current use.
[AArch64] Optimized memcmp.
This is an optimized memcmp for AArch64. This is a complete rewrite
using a different algorithm. The previous version split into cases
where both inputs were aligned, the inputs were mutually aligned and
unaligned using a byte loop. The new version combines all these cases,
while small inputs of less than 8 bytes are handled separately.
This allows the main code to be sped up using unaligned loads since
there are now at least 8 bytes to be compared. After the first 8 bytes,
align the first input. This ensures each iteration does at most one
unaligned access and mutually aligned inputs behave as aligned.
After the main loop, process the last 8 bytes using unaligned accesses.
This improves performance of (mutually) aligned cases by 25% and
unaligned by >500% (yes >6 times faster) on large inputs.
* sysdeps/aarch64/memcmp.S (memcmp):
Rewrite of optimized memcmp.
Remove __qaddr_t.
bits/types.h defines a type __qaddr_t that is not used anywhere in
glibc. It doesn't appear to be widely used outside glibc either
(judging by codesearch.debian.net, where hits are generally copies of
definitions of this type, not uses), so it seems appropriate to remove
this type, which this patch does.
Tested for x86_64.
* posix/bits/types.h (__qaddr_t): Remove.
Fix uc_* namespace (bug 21457).
The standard members of ucontext_t, in all standard versions with that
type, are uc_link, uc_sigmask, uc_stack and uc_mcontext.
The uc_* namespace is mostly reserved for additions to the structure.
However, in XPG4.2, it's only reserved when <ucontext.h> is included,
not when <signal.h> is included, while <signal.h> is required to
define ucontext_t (but not allowed to make visible other symbols from
<ucontext.h>). Thus, nonstandard members should avoid uc_* names.
Some already do use __uc_*, but others don't; most architectures (all
except ia64, I think) have a member uc_flags and some have additional
members beyond that.
This patch makes nonstandard members have an __ prefix unless
__USE_MISC is defined. Members whose names indicate they are solely
padding / reserved for future use are renamed unconditionally to use
the __glibc_reserved1 naming convention.
This is part of the preparation for a revised version of the
mcontext_t / sigcontext patch to be able to eliminate all 13 of the
miscellaneous XFAILs in conform/Makefile, rather than only 11 of them
as at present (at least one further fix on top of this one will be
needed for that as well).
Tested for x86_64, and with build-many-glibcs.py.

aarch64: Optimized memcpy for Qualcomm Falkor processor
This is an optimized implementation of the memcpy routine that gives a
significant gain in performance for all sizes of copies on the
Qualcomm Falkor processor. A detailed rationale of the implementation
is written in a comment in the patch.
This implementation improves time for copies up to 128 bytes by up to
15% and for larger copies by up to 35% in the glibc
microbenchmark. The memcpy-random benchmark sees improvements in all
sizes in the range of 13%-18%.
Here are the full numbers extracted from the glibc microbenchmark
using the commands:

New macro.
Do not use __ptr_t.
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *. void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.
Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net). I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.

Fix XPG4.2 bits/sigaction.h namespace (bug 21899).
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.
This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.
For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round. This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.
For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.
(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)
Tested for x86_64, and with build-many-glibcs.py.

Consistently use uintN_t not u_intN_t everywhere.
This patch changes the remaining uses of the old nonstandard u_intN_t
types in glibc to use the C99 uintN_t instead, except for the
definitions of those typedefs and the tests of them in the c++-types
test. This follows the previous such fix for libm, and being
consistent in using uintN_t makes sense as a global cleanup.

Remove __long_double_t.
sys/cdefs.h has a macro __long_double_t used in two places in glibc.
long double is a standard part of C since C89; there is no need for
such an alias for it. This patch removes that macro and uses long
double directly everywhere. As an implementation-namespace,
undocumented symbol, it should not be considered part of the API for
users, and codesearch.debian.net shows no sign of it being used
outside glibc in a way that would break with this patch.

Consistently use uintN_t not u_intN_t in libm.
This patch changes libm code to make consistent use of C99 uintN_t
types instead of sometimes using those and sometimes using the older
nonstandard u_intN_t names. This makes sense as a cleanup in its own
right, and also facilitates merges to GCC's libquadmath (which gets
the types from stdint.h and so may not have u_intN_t available at
all).

Fix tgmath.h for __int128 (bug 21686).
When a tgmath.h macro is passed a double argument and an argument of
type __int128, it generates a call to a long double function (although
the result still gets converted to type double). __int128 is similar
enough to integer types that it should be handled consistently like
them, so always like double for these macros rather than sometimes
like double and sometimes like long double. This patch fixes the
logic accordingly and makes gen-tgmath-tests.py generate tests for
__int128.
Tested for x86_64 and x86.

Fix tgmath.h for bit-fields (bug 21685).
The tgmath.h macros produce errors for bit-field arguments, because
they apply sizeof and typeof to the arguments. This patch fixes them
to use unary + systematically before using sizeof or typeof on
arguments that might be bit-fields (note that __real__ of a bit-field
is still a bit-field for this purpose, since it's an lvalue).
gen-tgmath-tests.py is extended to add tests for this case.
Tested for x86_64.
