| | | | | | | | | | | | | | | | | | | | | | | | | [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

| | | | | | | | | | | | | | | | | | | | [compiler-rt] Include system headers before optionally defining HWCAP macros In https://reviews.llvm.org/D141285 the optional definitions of `HWCAP` macros were moved to before their usage. 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. Move the system header includes to just before the optional definitions, to avoid this problem.

| | | | | | | | | | | | | | | | | As reported by Ronald, adding the out-of-line LSE atomics helpers for aarch64 to compiler-rt was not sufficient to link programs using these, as they also require a __aarch64_have_lse_atomics global. This is initialized in compiler-rt's lib/builtins/cpu_model.c, roughly similar to the x86 CPU model and feature detection in that file. Since upstream does not yet have a FreeBSD specific implementation for getting the required information, add a simple one that should work for now, while I try to get it sorted with the LLVM people.

To address this, add implementations for the functions from compiler-rt to the system compiler support libraries, e.g. libcompiler_rt.a and and libgcc_s.so. This also needs a small fixup in compiler-rt's atomic.c, to ensure that 32-bit mips can build correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reapply r230021 (by ed): Add a workaround to prevent endless recursion in compiler-rt. SPARC and MIPS CPUs don't have special instructions to count leading/trailing zeroes. The compiler-rt library provides fallback rountines for these. The 64-bit routines, __clzdi2 and __ctzdi2, are implemented as simple wrappers around the compiler built-in __builtin_clz(), assuming these will expand to either 32-bit CPU instructions or calls to __clzsi2 and __ctzsi2. Unfortunately, our GCC 4.2 probably thinks that because the operand is stored in a 64-bit register, it might just be a better idea to invoke its 64-bit equivalent, simply resulting into endless recursion. Fix this by defining __builtin_clz and __builtin_ctz to __clzsi2 and __ctzsi2 explicitly. Reapply r276851: Update compiler-rt to trunk r224034. This brings a number of new builtins, and also the various sanitizers. Support for these will be added in a later commit. Notes: svn path=/projects/clang1100-import/; revision=363773

* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-20354-0/+24972
This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
