[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

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.

tsan in some cases starts ignoring interceptors and only calls the
intercepted functions. But for realpath the behavior for NULL second argument
was only handled in the interceptor and intercepted function was the one
found by dlsym which is often one that doesn't handle NULL as second argument.
Fixed by using dlvsym with "GLIBC_2.3" if possible for intercepted function
and don't emulate behavior in the wrapper.

[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.

The Linux kernel has removed the interface to cyclades from
the latest kernel headers[1] due to them being orphaned for the
past 13 years.
libsanitizer uses this header when compiling against glibc, but
glibcs itself doesn't seem to have any references to cyclades.
Further more it seems that the driver is broken in the kernel and
the firmware doesn't seem to be available anymore.
As such since this is breaking the build of libsanitizer (and so the
GCC bootstrap[2]) I propose to remove this.

As mentioned in the PR, SIGSTKSZ is no longer a compile time constant in
glibc 2.34 and later, so
static const uptr kAltStackSize = SIGSTKSZ * 4;
needs dynamic initialization, but is used by a function called indirectly
from .preinit_array and therefore before the variable is constructed.

die with:

The change in major version (and the increment from Darwin19 to 20)
caused libtool tests to fail which resulted in incorrect build settings
for shared libraries.
We take this opportunity to sort out the shared undefined symbols state
rather than propagating the current unsound behaviour into a new rev.
This change means that we default to the case that missing symbols are
considered an error, and if one wants to allow this intentionally, the
confiuration for that case should be set appropriately.
Three existing cases need undefined dynamic lookup:
libitm, where there is already a configuration mechanism to add the
flags.
libcc1, where we add simple configuration to add the flags for Darwin.
libsanitizer, where we can add to the existing extra flags.

In `GetGlobalSizeFromDescriptor` we use `dladdr` to get info on the the
current address. `dladdr` returns 0 if it failed.
During testing on Linux this returned 0 to indicate failure, and
populated the `info` structure with a NULL pointer which was
dereferenced later.
This patch checks for `dladdr` returning 0, and in that case returns 0
from `GetGlobalSizeFromDescriptor` to indicate failure of identifying
the address.
This occurs when `GetModuleNameAndOffsetForPC` succeeds for some address
not in a dynamically loaded library. One example is when the found
"module" is '[stack]' having come from parsing /proc/self/maps.

Glibc has recently introduced changed to the mode field in ipc_perm
in commit 2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this
means that the mode field no longer has the same size.
This causes an assert failure against libsanitizer's internal copy
of ipc_perm. Since this change can't be easily detected I am adding
arm to the list of targets that are excluded from this check. libsanitizer
doesn't use this field (and others, it in fact uses only 1 field) so this check
can be ignored.
Padding bits were used by glibc when the field was changed so sizeof and offsets
of the remaining fields should be the same.

In FDPIC mode, we set -fPIE unless the user provides -fno-PIE, -fpie,
-fPIC or -fpic: indeed FDPIC code is PIC, but we want to generate code
for executables rather than shared libraries by default.
We also make sure to use the --fdpic assembler option, and select the
appropriate linker emulation.
At link time, we also default to -pie, unless we are generating a
shared library or a relocatable file (-r). Note that static link is
not supported as it requires specifying the dynamic linker because the
executable still has to relocate itself at startup.
We also force 'now' binding since lazy binding is not supported.
We should also apply the same behavior for -Wl,-Ur as for -r, but I
couldn't find how to describe that in the specs fragment.

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.

[PowerPC][tsan] Update tsan to handle changed memory layouts in newer kernels
In more recent Linux kernels with 47 bit VMAs the layout of virtual memory
for powerpc64 changed causing the thread sanitizer to not work properly. This
patch adds support for 47 bit VMA kernels for powerpc64.
Tested on several 4.x and 3.x kernel releases.
Regtested/bootstrapped on ppc64le-linux with kernel 4.14; applying to
trunk/8.3.

When shadow stack from Intel CET is enabled, the first instruction of all
indirect branch targets must be a special instruction, ENDBR.
lib/asan/asan_interceptors.cc has
...
int res = REAL(swapcontext)(oucp, ucp);
...
REAL(swapcontext) is a function pointer to swapcontext in libc. Since
swapcontext may return via indirect branch on x86 when shadow stack is
enabled, as in this case,
int res = REAL(swapcontext)(oucp, ucp);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This function may be
returned via an indirect branch.
Here compiler must insert ENDBR after call, like
call *bar(%rip)
endbr64
I opened an LLVM bug:
https://bugs.llvm.org/show_bug.cgi?id=38207
to add the indirect_return attribute so that it can be used to inform
compiler to insert ENDBR after REAL(swapcontext) call. We mark
REAL(swapcontext) with the indirect_return attribute if it is available.
This fixed:

As mentioned in <http://gcc.gnu.org/ml/gcc/2018-03/msg00133.html>
the bogus adjustment to 160 from 144 (which is reverted here),
is a single-token commit in upstream r301307, an attempt to
correct a failed build due to an upstream change to compile the
runtime with D_FILE_OFFSET_BITS=64. The correct fix is here:
just use the right include. Yes, user-struct-stat64-as-stat is
actually 160 for MIPS o32 and I hear user-struct-stat is also
160 for n32. There are additional fields appended for
user-struct-stat! I guess for MIPS it's as bad as it gets for
mixing up kernel and user struct stat. The context of the patch
doesn't show that in the #else there's the correct include, the
one for <asm/stat.h> to get the kernel-struct-stat. If you
can't compile it, IMHO the kernel headers are just too old; 3.2
is fine for example.

When one uses ld.gold to build gcc, the thread sanitizer doesn't work,
because gold is more conservative when applying TLS relaxations than
ld.bfd. In this case a missing initial-exec attribute on a declaration
causes gcc to assume the general dynamic model. With ld.bfd this gets
relaxed to initial exec when linking the shared library, so the missing
attribute doesn't matter. But ld.gold doesn't perform this optimization
and this leads to crashes on tsan instrumented binaries.
See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78294
and: https://sourceware.org/bugzilla/show_bug.cgi?id=20805
The fix is easy, just add the missing attribute.
