Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

While trying to build gdb on latest openSUSE Tumbleweed, I noticed the
following warning,
checking for makeinfo... makeinfo --split-size=5000000
configure: WARNING:
*** Makeinfo is too old. Info documentation will not be built.
then I checked the version of makeinfo, it said,
======
$ makeinfo --version

After digging a little bit, it became quite obvious that a dot is
missing in regexp that makes it impossible to match versions higher than
7.0, and here's the solution:
- | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9][0-9])' >/dev/null 2>&1; then
+ | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9]\.[0-9])' >/dev/null 2>&1; then
However, Eli pointed out that the solution above has another problem: it
will stop working when Texinfo 10.1 will be released. Meanwhile, he
suggested to solve this problem permanently. That is, we don't care
about the minor version for Texinfo > 6.9, we only care about the major
version.
In this way, the problem will be resolved permanently, thanks to Eli.
libctf/ChangeLog:
* configure: Regenerated.
* configure.ac: Update regexp to match versions higher than 7.0.

The libctf testsuite uses Tcl try/catch to trap run_output errors. This
is only supported in reasonably recent Tcls, so we detect the lack of
try/catch and suppress the testsuite via an Automake conditional in its
absence.
But this turns out not to work: Automake produces a check-DEJAGNU target
regardless of the value of this conditional and sticks it in an
unconditionally-executed part of the makefile, so the testsuite gets
executed anyway, and fails with a nasty-looking syntax error. We can't
disable it by taking "dejagnu" out of AUTOMAKE_OPTIONS, because if you
do that Automake stops you using RUNTEST, RUNTESTFLAGS and other
variables users would expect to work.
So move to disabling the testsuite from inside the testsuite itself,
importing the value of the former Automake conditional as a Tcl variable
and exiting very early in default.exp if it's false.
* configure.ac (TCL_TRY): No longer an Automake conditional.
Rename to...
(HAVE_TCL_TRY): ... this.
* Makefile.am: Drop TCL_TRY.
(development.exp): Set have_tcl_try.

This patch is essentially a revert of
commit-id: 8818c80cbd4116ef5af171ec47c61167179e225c
(libctf: Add ZSTD_LIBS to LIBS so that ac_cv_libctf_bfd_elf can be true)

The configure check for ELF support in BFD uses the AC_TRY_LINK. If

The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

This avoids a recursive make into the doc subdir and speeds up the

It's been a long time since most of this was written: it's long past
time to put it in the binutils source tree. It's believed correct and
complete insofar as it goes: it documents format v3 (the current
version) but not the libctf API or any earlier versions. (The
earlier versions can be read by libctf but not generated by it, and you
are highly unlikely ever to see an example of any of them.)

Checking for linker versioning by just grepping ld --help output for
mentions of --version-script is inadequate now that Solaris 11.4
implements a --version-script with different semantics. Try linking a
test program with a small wildcard-using version script with each
supported set of flags in turn, to make sure that linker versioning is
not only advertised but actually works.
The Solaris "GNU-compatible" linker versioning is not quite
GNU-compatible enough, but we can work around the differences by
generating a new version script that removes the comments from the
original (Solaris ld requires #-style comments), and making another
version script for libctf-nonbfd in particular which doesn't mention any
of the symbols that appear in libctf.la, to avoid Solaris ld introducing
corresponding new NOTYPE symbols to match the version script.

The address sanitizer contains a redirector that captures dlopen calls,
so checks for dlopen with AC_SEARCH_LIBS will always conclude that
dlopen is present when the sanitizer is on. This means it won't add
-ldl to LIBS even if needed, and the immediately-following attempt to
actually link with -lbfd will fail because libbfd also needs dlsym,
which ASAN does *not* contain a redirector for.
If we check for dlsym instead of dlopen, the check works whether ASAN is
on or off. (bfd uses both in close proximity: if it needs one, it will
always need the other.)

Right now, these libraries hardwire -L../intl -lintl on a few fixed
platforms, which works fine on those platforms but on other platforms
leads to shared libraries that lack libintl_* symbols when configured
--with-included-gettext, and/or static libraries that contain libintl as
*another* static library. If we instead use the LIBINTL variable
defined in ../intl/config.intl, this gives us the right thing on all
three classes of platform (gettext in libc, gettext in system libintl,
gettext in ../intl/libintl.a).. This also means we can rip out some
Darwin-specific machinery from configure.ac and also simplify the Cygwin
side.
This also means that the libctf testsuite (and other places that include
libbfd, libopcodes or libctf) don't need to grow libintl dependencies
just on account of those libraries (though they still need such
dependencies if they themselves use gettext machinery).

This complex morass inherited from libopcodes, which endeavours to
implement the effect of specifying ../bfd/libbfd.la in _LIBADD without
actually doing so, appears to be working around a libtool bug which as
far as I can see is no longer present (i.e., the install directory no
longer appears in -L arguments in libtool link-mode invocations, so
there is no danger of picking up old libbfds or other dependent
libraries).
Replaced with a simple reference to libbfd.la in the appropriate place.
Also adjusted things a little more so that libctf.la and libctf-nobfd.la
are self-contained, even when linking statically. This opens up the
possibility of running libtool to link against libctf from inside the
(upcoming) testsuite.

We gettextize under our package name, which we change to a more
reasonable 'libctf'. Our internationalization support is mostly
provided by ctf-intl.h, which is a copy of opcodes/opintl.h with
the non-gettext_noop N_() expansion debracketed to avoid pedantic
compiler warnings.
The libctf error strings returned by ctf_errmsg are marked up for
internationalization.

This adds the core deduplicator that the ctf_link machinery calls
(possibly repeatedly) to link the CTF sections: it takes an array
of input ctf_file_t's and another array that indicates which entries in
the input array are parents of which other entries, and returns an array
of outputs. The first output is always the ctf_file_t on which
ctf_link/ctf_dedup/etc was called: the other outputs are child dicts
that have the first output as their parent.

This lets other programs read and write CTF-format data.
Two versioned shared libraries are created: libctf.so and
libctf-nobfd.so. They contain identical content except that
libctf-nobfd.so contains no references to libbfd and does not implement
ctf_open, ctf_fdopen, ctf_bfdopen or ctf_bfdopen_ctfsect, so it can be
used by programs that cannot use BFD, like readelf.
The soname major version is presently .0 until the linker API

operating systems have a qsort_r that has a different prototype
but which still has a pair of pointers in the right places (the last two
args are interchanged): so use AC_LINK_IFELSE to check for both
known variants of qsort_r(), and swap their args into a consistent order
in a suitable inline function. (The code for this is taken almost
unchanged from gnulib.)
(Now we are not using AC_LIBOBJ any more, we can use a better name for
the qsort_r replacement as well.)

- Use of nonportable <endian.h>
- Use of qsort_r
- Use of zlib without appropriate magic to pull in the binutils zlib
- Use of off64_t without checking (fixed by dropping the unused fields
that need off64_t entirely)
- signedness problems due to long being too short a type on 32-bit
platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be
used only for functions that return ctf_id_t
- One lingering use of bzero() and of <sys/errno.h>
All fixed, using code from gnulib where possible.
Relatedly, set cts_size in a couple of places it was missed
(string table and symbol table loading upon ctf_bfdopen()).
