Jakub Jelinek 2379cbb94b libsanitizer: On aarch64 use hint #34 in prologue of libsanitizer functions 
When gcc is built with -mbranch-protection=standard, running sanitized
programs doesn't work properly on bti enabled kernels.

This has been fixed upstream with
https://github.com/llvm/llvm-project/pull/84061

The following patch cherry picks that from upstream.

For trunk we should eventually do a full merge from upstream, but I'm hoping
they will first fix up the _BitInt libubsan support mess.

YunQiang Su 557dbbac8e Sanitizer/MIPS: Use $t9 for preemptible function call 
Currently, almost all of the shared libraries of MIPS, rely on $t9
to get the address of current function, instead of PCREL instructions,
even on MIPSr6. So we have to set $t9 properly.

To get the address of preemptible function, we need the help of GOT.
MIPS/O32 has .cpload, which can help to generate 3 instructions to get GOT.
For __mips64, we can get GOT by:

lui $t8, %hi(%neg(%gp_rel(SANITIZER_STRINGIFY(TRAMPOLINE(func)))))
daddu $t8, $t8, $t9
daddiu $t8, $t8, %hi(%neg(%gp_rel(SANITIZER_STRINGIFY(TRAMPOLINE(func)))))

And then get the address of __interceptor_func, and jump to it

ld $t9, %got_disp(_interceptor" SANITIZER_STRINGIFY(func) ")($t8)
jr $t9

Solaris as apparently doesn't accept %function and requires @function

Jakub Jelinek 28219f7f99 libsanitizer: merge from upstream (c425db2eb558c263) 
The following patch is result of libsanitizer/merge.sh
from c425db2eb558c263 (yesterday evening).

Bootstrapped/regtested on x86_64-linux and i686-linux (together with
the follow-up 3 patches I'm about to post).

BTW, seems upstream has added riscv64 support for I think lsan/tsan,
so if anyone is willing to try it there, it would be a matter of
copying e.g. the s390*-*-linux* libsanitizer/configure.tgt entry
to riscv64-*-linux* with the obvious s/s390x/riscv64/ change in it.

Wei Mi f35db108b9 Import the asan runtime library into GCC tree 
This patch imports the runtime library in the GCC tree, ensures that
-lasan is passed to the linker when -faddress-sanitizer is used and
sets up the build system accordingly.

ChangeLog:

	* configure.ac: Add libsanitizer to target_libraries.
	* Makefile.def: Ditto.
	* configure: Regenerate.
	* Makefile.in: Regenerate.
	* libsanitizer: New directory for asan runtime.  Contains an empty
	tsan directory.

gcc/ChangeLog:

	* gcc.c (LINK_COMMAND_SPEC): Add -laddress-sanitizer to link
	command if -faddress-sanitizer is on.

libsanitizer:

	Initial checkin: migrate asan runtime from llvm.
