Since the sanitizer merge in commit r15-5164-gfa321004f3f628 of GCC
which entails LLVM commit 61a6439f35b6de28ff4aff4450d6fca970292fd5, GCCs
bootstrap is broken on s390 -m31. This is due to commit
ec68dc1ca4d967b599f1202855917d5ec9cae52f which introduces stricter type
checking which is why GCC bootstrap fails with
```

The culprit seems to be that we don't check for equality of type sizes
anymore but rather whether the types are indeed the same. On s390 -m31
we have that `sizeof(int)==sizeof(long)` holds which is why previously
the checks succeeded. They fail now because
```
size_t => unsigned long
ssize_t => long
ptrdiff_t => int
::SSIZE_T => __sanitizer::sptr => int
::PTRDIFF_T => __sanitizer::sptr => int
```
This is fixed by mapping `SSIZE_T` to `long` in the end.
```
typedef long ssize;
typedef sptr ssize;
```

We aren't the master repository for the sanitizers and clearly upstream introduces various extensions in the code. All we care about is whether it builds and works fine with GCC, so -pedantic flag is of no use to us, only maybe to upstream if they cared about it (which they clearly don't). The following patch removes those and fixes some whitespace nits at the same time. 2024-11-25 Jakub Jelinek <jakub@redhat.com> PR sanitizer/117732 * asan/Makefile.am (AM_CXXFLAGS): Remove -pedantic.

While compiling libsanitizer for aarch64-linux-gnu, I noticed the new warning:
```
../../../../libsanitizer/asan/asan_interceptors.cpp: In function ‘char* ___interceptor_strcpy(char*, const char*)’:
../../../../libsanitizer/asan/asan_interceptors.cpp:554:6: warning: ‘if constexpr’ only available with ‘-std=c++17’ or ‘-std=gnu++17’ [-Wc++17-extensions]

```
So compile-rt upstream compiles this as gnu++17 (the current defualt for clang), so let's update it
to be similar.
Build and tested on aarch64-linux-gnu.

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. 2024-09-05 Jakub Jelinek <jakub@redhat.com> * sanitizer_common/sanitizer_asm.h: Cherry-pick llvm-project revision 1c792d24e0a228ad49cc004a1c26bbd7cd87f030. * interception/interception.h: Likewise.
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 Upstream-Commit: 0a64367a72f1634321f5051221f05f2f364bd882 libsanitizer * interception/interception.h (substitution_##func_name): Use macro C_ASM_TAIL_CALL. * sanitizer_common/sanitizer_asm.h: Define C_ASM_TAIL_CALL for MIPS with help of t9.
The recent libsanitizer import broke the build on Solaris/SPARC with the native as: /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol "__sanitizer_internal_memset" is used but not defined /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol "__sanitizer_internal_memcpy" is used but not defined /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol "__sanitizer_internal_memmove" is used but not defined Since none of the alternatives considered in the PR worked out, this patch checks if the assembler does support symbol assignment, disabling the code otherwise. This returns the code to the way it was up to LLVM 16. Bootstrapped without regressions on sparc-sun-solaris2.11 (as and gas) and i386-pc-solaris2.11 (as and gas). 2023-11-23 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> libsanitizer: PR sanitizer/112563 * configure.ac (libsanitizer_cv_as_sym_assign): Check for assembler symbol assignment support. * configure: Regenerate. * asan/Makefile.am (DEFS): Add @AS_SYM_ASSIGN_DEFS@. * Makefile.in, asan/Makefile.in, hwasan/Makefile.in, interception/Makefile.in, libbacktrace/Makefile.in, lsan/Makefile.in, sanitizer_common/Makefile.in, tsan/Makefile.in, ubsan/Makefile.in: Regenerate.
Solaris as apparently doesn't accept %function and requires @function instead.

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.
