[PATCH,V6 04/10] libctfframe: add the CTF Frame library

Indu Bhagat indu.bhagat@oracle.com
Tue Aug 2 08:04:46 GMT 2022


From: Weimin Pan <weimin.pan@oracle.com>

[Changes from V5]
 - testuite fixes for various warnings on x86_64-linux.
 - libctfframe testsuite now uses recursive makefiles for building the
   test programs.  This keeps the test machinery simple.  These tests
   use the host compiler to build the tests.
 - The test programs in libctfframe testsuite now use dejagnu pass () /
   fail () methods.
[End of changes from V5]

[No changes in V4]

[Changes from V3]
 - Bugfixes around endian flipping code.
 - ctf_frame_find_fre () API now performs the checks according to the
   type of FDE:
   For CTF_FRAME_DESCRIPTOR_ENTRY_TYPE_ADDRINC: return the entry where
   (PC >= fre_start_addr)
   For CTF_FRAME_DESCRIPTOR_ENTRY_TYPE_ADDRMASK: return the entry where
   (PC & MASK >= MASK)
 - Additional testcases for CTF Frame encoder and endian flipping.
[End of changes from V3]

[Changes from V2]
 - consistent use of terminology around CTF Frame and its components.
 - Added testsuite for CTF frame decoder.
[End of changes from V2]

[Changes from V1]
 - bugfixes

libctfframe is a library that allows you to:
- decode a .ctf_frame section
- probe and inspect a .ctf_frame section
- encode (and eventually write) a .ctf_frame section.

This library is currently being used by the linker, readelf, objdump and
the unwinder.

The file include/ctf-frame-api.h defines the user-facing APIs for decoding,
encoding and probing .ctf_frame sections. A set of error codes together
with their error message strings are also defined.

Endian flipping is performed automatically at read and write time, if
cross-endianness is detected.

PS: libctfframe/configure has NOT been included in the patch.  Please
regenerate.

+#
+# Of course, Automake must honor this variable whenever it calls a

+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.

+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative

+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
