I get some changes when running `autoreconf -vf` in the gdb directory,
fix that.
I did a bisect, it appears to have been introduced in this commit, not
sure why we haven't spotted that before.

This patch changes the GDB build system in order to use libtool to
link the several built executables. This makes it possible to refer
to libtool libraries (.la files) in CLIBS.
As an application of the above,
BFD now refers to ../libbfd/libbfd.la
OPCODES now refers to ../opcodes/libopcodes.la
LIBBACKTRACE_LIB now refers to ../libbacktrace/libbacktrace.la
LIBCTF now refers to ../libctf/libctf.la
NOTE1: The addition of libtool adds a few new configure-time options
to GDB. Among these, --enable-shared and --disable-shared, which were
previously ignored. Now GDB shall honor these options when linking,
picking up the right version of the referred libtool libraries
automagically.
NOTE2: I have not tested the insight build.
NOTE3: For regenerating configure I used an environment with Autoconf
2.69 and Automake 1.15.1. This should match the previously
used version as announced in the configure script.
NOTE4: Now the installed shared objects libbfd.so, libopcodes.so and
libctf.so are used by gdb if binutils is installed with
--enable-shared.
Testing performed:
- --enable-shared and --disable-shared (the default in binutils) work
as expected: the linked executables link with the archive or shared
libraries transparently.
- Makefile.in modified for EXEEXT = .exe. It installs the binaries
just fine. The installed gdb.exe runs fine.
- Native build regtested in x86_64. No regressions found.
- Cross build for aarch64-linux-gnu built to exercise
program_transform_name and friends. The installed
aarch64-linux-gnu-gdb runs fine.

Move the 64-bit bfd logic out of bfd/configure.ac and into bfd64.m4
under config so it can be shared between all the other subdirs.
This replaces want64 with enable_64_bit_bfd which was already being
declared, but not used directly.
These dirs don't use automake, so use AC_CONFIG_MACRO_DIRS to specify
../config as a search dir for m4 macros. This allows removal of a lot
of hand-written m4_include's from acinclude.m4 files, and simplifies
use of `aclocal` or `autoreconf` as manual -I is not needed.
Any code using AC_DEBUGINFOD from this dir is using -I../config when
running aclocal, so an explicit include on pkg.m4 is unnecessary:
aclocal will find the pkg.m4 in this dir just as easily. This is
seen in the only two dirs that use AC_DEBUGINFOD (binutils & gdb)
as their aclocal.m4 already has m4_include on config m4 files.
The include as written only works if aclocal is run on a dir that is
at the same level of config/. Any other depth will fail.
./
|-- config/
|-- binutils/ # works
|-- gdb/ # works
`-- sim/ # works
`-- <port>/ # fails
It fails even if AC_DEBUGINFOD itself isn't used:
sim/bfin/ $ aclocal -I../../config
aclocal-1.15: error: ../../config/debuginfod.m4:8: file '../config/pkg.m4' does not exist
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/.
Problem 9:

This is the previously mentioned patch to get rid of
unstructured/ioctl-based procfs support in procfs.c. Given that support
for structured procfs was introduced in Solaris 2.6 back in 1997 and
we're just removing support for Solaris < 10, there's no point in
carrying that baggage (and tons of support for IRIX and OSF/1 as well)
around any longer.
Most of the patch should be straightforward (removing support for
!NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks).
Only a few points need explanations:
* <sys/syscall.h> was already included unconditionally in most places,
so there's no need to have guards in a few remaining ones.
* configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so
NEW_PROC_API detection for those in configure.ac can go.
* I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1.
Theoretically, it would be better to include <procfs.h> on Solaris
(which includes that define), but that breaks the build over
<procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux.
* I've regenerated syscall_table[] in proc-events.c with a small script
from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no
traces of older Solaris versions and other OSes left.
* prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX
doesn't use procfs.c any longer, so all related code can go.
The patch was generated with diff -w so one can easier see changes
without being distracted by simple reindentations.
So far, it has only been compiled and smoke-tested on
amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and
x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3
vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on
Solaris 10 etc.), but it's enough to get a first impression how much
cleanup is possible here.

config/i386/xm-cygwin.h, config/rs6000/xm-rs6000.h
(HAVE_SIGSETMASK): Remove.
* aclocal.m4, config.in, configure
(AC_FUNC_SETPGRP): Add.
* aclocal.m4, configure, config.in: Regenerated.
* inflow.c (gdb_setpgid): Get rid of NEED_POSIX_SETPGID and
SETPGRP_ARGS. Always use setpgid if it is available, fall back on
setpgrp if it isn't. Use SETPGRP_VOID (defined by autoconf) to
distinguish between the two setpgrp flavours.
* config/xm-sysv4.h, config/arm/xm-linux.h,
config/i386/xm-i386aix.h, config/i386/xm-sco.h,
config/i386/xm-linux.h, config/i386/xm-ptx.h,
config/m68k/xm-linux.h, config/powerpc/xm-linux.h,
config/sparc/xm-linux.h, config/sparc/xm-sun4sol2.h,
config/ia64/xm-linux.h (NEED_POSIX_SETPGID): Remove.
* config/rs6000/xm-rs6000.h (SETPGRP_ARGS): Remove.
* Makefile.in: Add GDBTK_CFLAGS - this is now used to hold
-fwritable-strings when compiling with Tk8.1.
* configure.in: Add GDBTK_CFLAGS, set it to -fwritable-strings for
Tcl/Tk8.1 & greater.
* acinclude.m4: Move the rest of the defines to find Itcl, Itk &
Tix from aclocal.m4 to here.
* aclocal.m4: regenerate.
* configure: regenerate.
* gdbtk-hooks.c (x_event): Tcl_ObjGetVar2 was removed from
Tcl8.1. Use Tcl_GetVar2 instead.
* gdbtk-hooks.c (gdbtk_trace_find): Fix up call to
Tcl_GlobalEvalObj for Tcl/Tk 8.1.
* gdbtk-hooks.c (gdbtk_trace_start_stop): Call to Tcl_EvalObj was
inefficient, replace with call to Tcl_GlobalEval.
* gdbtk.c: Don't swap out the Tcl_Alloc calls in gdbtk.c. We took
care of that in Tcl itself for 8.1.
* gdbtk.c: Remove const from the script string since Tcl8.1 has
taken to scribbling sentinals into strings passed to it again...
* gdbtk-cmds.c (wrapped_call): Change declaration of 1st arg from
char * to PTR to eliminate warning.
* gdbtk-cmds.c (perror_with_name_wrapper): Ditto
