70b043845d libsanitizer: Use SSE to save and restore XMM registers
Use SSE, instead of AVX, to save and restore XMM registers to support

32377c1019 Fix PR 62157: disclean in libsanitizer not working
So what is happening is DIST_SUBDIRS contains the conditional
directories which is wrong, so we need to force DIST_SUBDIRS
to be the same as SUBDIRS as recommened by the automake manual.

OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
Also now make distclean works inside libsanitizer directory.

    [sanitizer] No THREADLOCAL in qsort and bsearch

    qsort can reuse qsort_r if available.
    bsearch always passes key as the first comparator argument, so we
    can use it to wrap the original comparator.

    tsan: avoid extra call indirection in unaligned access functions

    Currently unaligned access functions are defined in tsan_interface.cpp
    and do a real call to MemoryAccess. This means we have a real call
    and no read/write constant propagation.

    Unaligned memory access can be quite hot for some programs
    (observed on some compression algorithms with ~90% of unaligned accesses).

    Move them to tsan_interface_inl.h to avoid the additional call
    and enable constant propagation.
    Also reorder the actual store and memory access handling for
    __sanitizer_unaligned_store callbacks to enable tail calling
    in MemoryAccess.

    Depends on D107282.

    tsan: optimize test-only barrier

    The updated lots_of_threads.c test with 300 threads
    started running for too long on machines with low
    hardware parallelism (e.g. taskset -c 0-1).
    On lots of CPUs it finishes in ~2 secs. But with
    taskset -c 0-1 it runs for hundreds of seconds
    effectively spinning in the barrier in the sleep loop.

    We now have the handy futex API in sanitizer_common.
    Use it instead of the passive spin loop.
    It makes the test run only faster with taskset -c 0-1,
    it runs for ~1.5 secs, while with full parallelism
    it still runs for ~2 secs (but consumes less CPU time).

    Depends on D107131.

    [sanitizer] Fix __sanitizer_kernel_sigset_t endianness issue

    setuid(0) hangs on SystemZ under TSan because TSan's BackgroundThread
    ignores SIGSETXID. This in turn happens because internal_sigdelset()
    messes up the mask bits on big-endian system due to how
    __sanitizer_kernel_sigset_t is defined.

    Commit d9a1a53b8d80 ("[ESan] [MIPS] Fix workingset-signal-posix.cpp on
    MIPS") fixed this for MIPS by adjusting the __sanitizer_kernel_sigset_t
    definition. Generalize this by defining __SANITIZER_KERNEL_NSIG based
    on kernel's _NSIG and using uptr[] for __sanitizer_kernel_sigset_t.sig
    on all platforms.

Libsanitizer: merge from master.
Merged from revision b638b63b99d66786cb37336292604a2ae3490cfd.

The patch successfully bootstraps on x86_64-linux-gnu and
ppc64le-linux-gnu. I also tested ppc64-linux-gnu that exposed:
https://reviews.llvm.org/D80864 (which is fixed on master).

Abidiff looks happy and I made UBSAN and ASAN bootstrap on
x86_64-linux-gnu.

I'm planning to do merge from master twice a year, once now and
next time short before stage1 closes.

I am going to install the patches as merge from master is obvious
and I haven't made anything special.

e8e66971cd Add `--with-toolexeclibdir=' configuration option
Provide means, in the form of a `--with-toolexeclibdir=' configuration
option, to override the default installation directory for target
libraries, otherwise known as $toolexeclibdir.  This is so that it is
possible to get newly-built libraries, particularly the shared ones,
installed in a common place, so that they can be readily used by the
target system as their host libraries, possibly over NFS, without a need
to manually copy them over from the currently hardcoded location they
would otherwise be installed in.

In the presence of the `--enable-version-specific-runtime-libs' option
and for configurations building native GCC the option is ignored.

22e0527251 Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).
This patch updates GCC to use autoconf 2.69 and automake 1.15.1.
(That's not the latest automake version, but it's the one used by
binutils-gdb, with which consistency is desirable, and in any case
seems a useful incremental update that should make a future update to
1.16.1 easier.)

The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf.  Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree.  Autoconf 2.69 has Go support, so
local copies of that support are removed.  I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update.  Changes to how automake generates
runtest calls mean quotes are removed from RUNTEST definitions in five
lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm,
libphobos, libvtv; some others have RUNTEST definitions without
quotes, which are still OK); libgo and libphobos also get
-Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST
do not generate automake warnings.

Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory).  Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.

While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers.  Specifically, most of those warnings
were of the following form (example from libgfortran):

Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: 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.

I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed.  In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.

I've tested this with native, cross and Canadian cross builds.  The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.
