* compiler-rt: avoid segfaults when re-exec'ing with ASLRDimitry Andric2023-11-222-6/+7
| | | | | | | | | | | | | | | | | After 930a7c2ac67e ("compiler-rt: re-exec with ASLR disabled when necessary") and 96fe7c8ab0f6 ("compiler-rt: support ReExec() on FreeBSD"), binaries linked against the sanitizer libraries may segfault due to procctl(2) being intercepted. Instead, the non-intercepted internal_procctl() should be called. Similarly, the ReExec() function that re-executes the binary after turning off ASLR should not call elf_aux_info(3) and realpath(3), since these will also be intercepted. Instead, loop directly over the elf aux info vector to find the executable path, and avoid calling realpath(3) since it is actually unwanted for this use case.

| | | | | | | | | | | | | | | | | | | | | | | | | [builtins][Mips] Un-break FreeBSD build of __clear_cache Commit 674a17e9bbe8 ("MIPS/compiler_rt: use synci to flush icache on r6") completely removed the OS-specific guards under the guise of "For pre-r6, we can use cacheflush libc function, which is same on Linux and FreeBSD." However, the code in question had guards for Linux and OpenBSD, not Linux and FreeBSD, and FreeBSD does not have a cacheflush libc function as claimed, so this was neither the statement they intended to make nor was it sufficient justification for making the code completely unconditional. Whilst the upcoming FreeBSD 14 release has dropped support for MIPS, FreeBSD 13 has support for it. Fix this by only calling cacheflush on the OSes where it was previously called, and not on other OSes where it either definitely isn't available (FreeBSD) or is unknown (any other OS than the three mentioned in this commit). This is only needed for MFC'ing, as mips has been removed from 14-CURRENT. PR: 271047 MFC after: immediately

However, they were also moved to before the inclusion of system headers which can optionally define them. If any of those system headers then actually defined any of the `HWCAP` macros, it would result in a redefinition error.
