Subject: [PATCH,RFC 3/7] libctfframe: add the CTF Frame library
Date: Mon, 9 May 2022 10:41:27 -0700 [thread overview]
Message-ID: <20220509174127.3905875-1-indu.bhagat@oracle.com> (raw)
[PS: this patch does not include the auto-generated libctfframe/configure to
manage the size issues of the patch file.]
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 and objdump.
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.
ChangeLog:
* Makefile.def: Add libctfframe as new module with its
dependencies.
* Makefile.in: Regenerated.
* binutils/Makefile.am: Add libctfframe.
* binutils/Makefile.in: Regenerated.
* configure: Regenerated.
* configure.ac: Add libctfframe to host_libs.
* libctfframe/Makefile.am: New file.
* libctfframe/Makefile.in: New file.
* libctfframe/aclocal.m4: New file.
* libctfframe/config.h.in: New file.
* libctfframe/configure.ac: New file.
* libctfframe/ctf-frame-error.c: New file.
* libctfframe/ctf-frame-impl.h: New file.
* libctfframe/ctf-frame.c: New file.
include/ChangeLog:
* ctf-frame-api.h: New file.

+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# 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
+# $top_srcdir/$ac_aux_dir/missing
+# 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.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
