    libiberty: Fix build with GCC < 7

    Tobias reported on IRC that the linker fails to build with GCC 4.8.5.
    In configure I've tried to use everything actually used in the sha1.c
    x86 hw implementation, but unfortunately I forgot about implicit function
    declarations.  GCC before 7 did have <cpuid.h> header and bit_SHA define
    and __get_cpuid function defined inline, but it didn't define
    __get_cpuid_count, which compiled fine (and the configure test is
    intentionally compile time only) due to implicit function declaration,
    but then failed to link when linking the linker, because
    __get_cpuid_count wasn't defined anywhere.

    The following patch fixes that by using what autoconf uses in AC_CHECK_DECL
    to make sure the functions are declared.

    libiberty: Fix pex_unix_wait return type

    The recent warning patches broke Solaris bootstrap:

    /vol/gcc/src/hg/master/local/libiberty/pex-unix.c:326:3: error: initialization of 'pid_t (*)(struct pex_obj *, pid_t,  int *, struct pex_time *, int,  const char **, int *)' {aka 'long int (*)(struct pex_obj *, long int,  int *, struct pex_time *, int,  const char **, int *)'} from incompatible pointer type 'int (*)(struct pex_obj *, pid_t,  int *, struct pex_time *, int,  const char **, int *)' {aka 'int (*)(struct pex_obj *, long int,  int *, struct pex_time *, int,  const char **, int *)'} [-Wincompatible-pointer-types]

          |   ^~~~~~~~~~~~~
    /vol/gcc/src/hg/master/local/libiberty/pex-unix.c:326:3: note: (near initialization for 'funcs.wait')

    While pex_funcs.wait expects a function returning pid_t, pex_unix_wait
    currently returns int.  However, on Solaris pid_t is long for 32-bit,
    but int for 64-bit.

    This patches fixes this by having pex_unix_wait return pid_t as
    expected, and like every other variant already does.

    Bootstrapped without regressions on i386-pc-solaris2.11,
    sparc-sun-solaris2.11, x86_64-pc-linux-gnu, and
    x86_64-apple-darwin23.1.0.

    c++: mangle function template constraints

    Per https://github.com/itanium-cxx-abi/cxx-abi/issues/24 and
    https://github.com/itanium-cxx-abi/cxx-abi/pull/166

    We need to mangle constraints to be able to distinguish between function
    templates that only differ in constraints.  From the latter link, we want to
    use the template parameter mangling previously specified for lambdas to also
    make explicit the form of a template parameter where the argument is not a
    "natural" fit for it, such as when the parameter is constrained or deduced.

    I'm concerned about how the latter link changes the mangling for some C++98
    and C++11 patterns, so I've limited template_parm_natural_p to avoid two
    cases found by running the testsuite with -Wabi forced on:

    template <class T, T V> T f() { return V; }
    int main() { return f<int,42>(); }

    template <int i> int max() { return i; }
    template <int i, int j, int... rest> int max()
    {
      int sub = max<j, rest...>();
      return i > sub ? i : sub;
    }
    int main() {  return max<1,2,3>(); }

    A third C++11 pattern is changed by this patch:

    template <template <typename...> class TT, typename... Ts> TT<Ts...> f();
    template <typename> struct A { };
    int main() { f<A,int>(); }

    I aim to resolve these with the ABI committee before GCC 14.1.

    We also need to resolve https://github.com/itanium-cxx-abi/cxx-abi/issues/38
    (mangling references to dependent template-ids where the name is fully
    resolved) as references to concepts in std:: will consistently run into this
    area.  This is why mangle-concepts1.C only refers to concepts in the global
    namespace so far.

    The library changes are to avoid trying to mangle builtins, which fails.

    Demangler support and test coverage is not complete yet.

        libiberty: Use x86 HW optimized sha1

    broke Solaris/x86 bootstrap with the native as:

    libtool: compile:  /var/gcc/regression/master/11.4-gcc/build/./gcc/gccgo -B/var/gcc/regression/master/11.4-gcc/build/./gcc/ -B/vol/gcc/i386-pc-solaris2.11/bin/ -B/vol/gcc/i386-pc-solaris2.11/lib/ -isystem /vol/gcc/i386-pc-solaris2.11/include -isystem /vol/gcc/i386-pc-solaris2.11/sys-include -fchecking=1 -minline-all-stringops -O2 -g -I . -c -fgo-pkgpath=internal/goarch /vol/gcc/src/hg/master/local/libgo/go/internal/goarch/goarch.go zgoarch.go

    gccgo: fatal error: Killed signal terminated program go1

    As is already done in a couple of other similar cases, this patches
    disables hwcaps support for libiberty.

    Initially, this didn't work because config/hwcaps.m4 uses target_os, but
    didn't ensure it is defined.

    Tested on i386-pc-solaris2.11 with as and gas.

    libiberty: Use x86 HW optimized sha1

    Nick has approved this patch (+ small ld change to use it for --build-id=),
    so I'm commiting it to GCC as master as well.

    If anyone from ARM would be willing to implement it similarly with
    vsha1{cq,mq,pq,h,su0q,su1q}_u32 intrinsics, it could be a useful linker
    speedup on those hosts as well, the intent in sha1.c was that
    sha1_hw_process_bytes, sha1_hw_process_block functions
    would be defined whenever
    defined (HAVE_X86_SHA1_HW_SUPPORT) || defined (HAVE_WHATEVERELSE_SHA1_HW_SUPPORT)
    but the body of sha1_hw_process_block and sha1_choose_process_bytes
    would then have #elif defined (HAVE_WHATEVERELSE_SHA1_HW_SUPPORT) for
    the other arch support, similarly for any target attributes on
    sha1_hw_process_block if needed.

    [PATCH v3] libiberty: Use posix_spawn in pex-unix when available.

    Hi,

    This patch implements pex_unix_exec_child using posix_spawn when
    available.

    This should especially benefit recent macOS (where vfork just calls
    fork), but should have equivalent or faster performance on all
    platforms.
    In addition, the implementation is substantially simpler than the
    vfork+exec code path.

    Tested on x86_64-linux.

    v2: Fix error handling (previously the function would be run twice in
    case of error), and don't use a macro that changes control flow.

    v3: Match file style for error-handling blocks, don't close
    in/out/errdes on error, and check close() for errors.

    c++: constrained hidden friends [PR109751]

    r13-4035 avoided a problem with overloading of constrained hidden friends by
    checking satisfaction, but checking satisfaction early is inconsistent with
    the usual late checking and can lead to hard errors, so let's not do that
    after all.

    We were wrongly treating the different instantiations of the same friend
    template as the same function because maybe_substitute_reqs_for was failing
    to actually substitute in the case of a non-template friend.  But we don't
    actually need to do the substitution anyway, because [temp.friend] says that
    such a friend can't be the same as any other declaration.

    After fixing that, instead of a redefinition error we got an ambiguous
    overload error, fixed by allowing constrained hidden friends to coexist
    until overload resolution, at which point they probably won't be in the same
    ADL overload set anyway.

    And we avoid mangling collisions by following the proposed mangling for
    these friends as a member function with an extra 'F' before the name.  I
    demangle this by just adding [friend] to the name of the function because
    it's not feasible to reconstruct the actual scope of the function since the
    mangling ABI doesn't distinguish between class and namespace scopes.

4a50820ee8 libiberty, ld: Use x86 HW optimized sha1
The following patch attempts to use x86 SHA ISA if available to speed
up in my testing about 2.5x sha1 build-id processing (in my case on
AMD Ryzen 5 3600) while producing the same result.
I believe AArch64 has similar HW acceleration for SHA1, perhaps it
could be added similarly.

Note, seems lld uses BLAKE3 rather than md5/sha1.  I think it would be
a bad idea to lie to users, if they choose --buildid=sha1, we should
be using SHA1, not some other checksum, but perhaps we could add some other
--buildid= styles and perhaps make one of the new the default.

Tested on x86_64-linux, both on Intel i9-7960X (which doesn't have
sha_ni ISA support) without/with the patch and on AMD Ryzen 5 3600
(which does have it) without/with the patch.

d0ac1c4488 Bump to autoconf 2.69 and automake 1.15.1
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:

c20a064233 Configury changes for obstack optimization
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.

	* configure.ac: Get size of size_t.
