GCC's config/ChangeLog since the last time this merge was done
(in the binutils-gdb commit 0b4d000cc4) is included at the
end of this commit message.
It is worth noting that the binutils-gdb commit 301a9420d9
added the file config/debuginfod.m4 which is not present in GCC's
config/ directory. This file is preserved, unmodified, after this
commit.
In order to regenerate all of the configure files, I configured with
--enable-maintainer-mode, and built the 'all' target. I then did the
same thing on a source tree without this patch, and only committed
those files that changed when this patch was added.

This patch addresses the multitude of bug reports about resource exhaustion
in libiberty's name demangling code. It adds a limit to the amount of
recursion that is allowed, before an error is triggered. It also adds a
new demangling option to disable this limit. (The limit is enabled by
default).

When trying to run the update-gnulib.sh script in gdb, I get this:
Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.
Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22. It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import. And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.
For autoconf, the 2.69 version is universally available, so it's an easy
choice. For automake, different distros and distro versions have
different automake versions. But 1.15.1 seems to be the most readily
available as a package. In any case, it's easy to build it from source.
I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case. They only specify a
lower bound for the acceptable version of automake/autoconf. That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version). In our case, we force people to use a
specific version anyway. For the autoconf version, we have the check in
config/override.m4 that enforces the version we want. It will be one
less thing to update next time we change autotools version.
I hit a few categories of problems that required some changes. They are
described below along with the chosen solutions.
Problem 1:
configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see:
configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
Solution 1:
Adjust the code based on the example at that URL.
Problem 2 (in zlib/):
Makefile.am: error: required file './INSTALL' not found
Makefile.am: 'automake --add-missing' can install 'INSTALL'
Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './AUTHORS' not found
Makefile.am: error: required file './COPYING' not found
Makefile.am: 'automake --add-missing' can install 'COPYING'
Solution 2:
Add the foreign option to AUTOMAKE_OPTIONS.
Problem 3:
doc/Makefile.am:20: error: support for Cygnus-style trees has been removed
Solution 3:
Remove the cygnus options.
Problem 4:
Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
Solution 4:
Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
already defined earlier).
Problem 5:
doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 5:
Rename .texinfo files to .texi.
Problem 6:
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 6:
Remove the hack at the bottom of doc/Makefile.am and use
the info-in-builddir automake option.
Problem 7:
doc/Makefile.am:35: error: required file '../texinfo.tex' not found
doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex'
Solution 7:
Use the no-texinfo.tex automake option. We also have one in
texinfo/texinfo.tex, not sure if we should point to that, or move it
(or a newer version of it added with automake --add-missing) to
top-level.
Problem 8:
Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
Makefile.am:131: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
Solution 8:
Use subdir-objects, that means adjusting references to some .o that will now
be in config/.

Provides defines used to determine whether glibc obstacks are
compatible. Generally speaking, 32-bit targets won't need to use
obstack.o from libiberty if glibc is used, while 64-bit targets will,
until glibc gets the new obstack code.

Building libiberty on Android currently fails with the error message
shown below. This was discovered by trying to build GDBserver
for Android, which stopped building after libiberty became
a GDBserver dependency.
Here is the error message:
[...]/getpagesize.c:64:1: error: redefinition of 'getpagesize'
In file included from /[...]/getpagesize.c:34:0:
/[...]/usr/include/unistd.h:171:23: note: previous definition of 'getpagesize' was here
And looking at the definition, one can see that it defined as
a static inline function...
static __inline__ int getpagesize(void) {
extern unsigned int __page_size;
return __page_size;
}
... which explains why the AC_CHECK_FUNCS test failed to detect
the function, since there is no associated symbol to be linked in.
This patch prevents getpagesize.c to be compiled in by hard-coding
the fact that getpagesize is available on android hosts.
libiberty/ChangeLog:
* configure.ac: Set AC_CV_FUNC_GETPAGESIZE to "yes" on
Android hosts.
* configure: Regenerate.
Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted. So we end up initializing properly
at the top only to reset it at the end all the time.
