| | | | | | | | | | | | | | | | | | | | | | | | | | | Implement computeHostNumHardwareThreads() for FreeBSD This retrieves CPU affinity via FreeBSD's cpuset(2) API, and makes LLVM respect affinity settings configured by the user via the cpuset(1) command. In particular, this allows to reduce the number of threads used on machines with high core counts, which can interact badly with parallelized build systems. This is particularly noticable with lld, which spawns lots of threads even for linking e.g. hello_world! This fix is related to PR48193, but does not adress the more fundamental problem, which is that LLVM by default grabs as many CPUs and/or threads as possible.

| | | | | | | | | | | | | | | | | | landed upstream: For llvm's internal function which retrieves the number of available "hardware threads", use cpuset_getaffinity(2) on FreeBSD, so it will honor processor sets configured by the cpuset(1) command. This should make it possible to avoid e.g. lld creating a huge number of threads on a machine with many cores, even for linking simple programs. This will also be submitted upstream.

| | | | | | | | | | | | | | | | | | | | [X86] SSE4_A should only imply SSE3 not SSSE3 in the frontend. SSE4_1 and SSE4_2 due imply SSSE3. So I guess I got confused when switching the code to being table based in D83273. Fixes PR47464 This should fix builds with -march=amdfam10 emitting SSSE3 instructions such as pshufb, which lead to programs crashing with SIGILL on such processors.

| | | | | | | | | | | | master 2e10b7a39b9, the last commit before the llvmorg-12-init tag, from which release/11.x was branched. Note that for now, I rolled back all our local changes to make merging easier, and I will reapply the still-relevant ones after updating to 11.0.0-rc1.

| | | | | | | | | | | | | | | | | | | | | getMainExecutable: Fix hand-rolled AT_EXECPATH for older FreeBSD Once we hit AT_NULL, we need to bail out of the loop; not just the enclosing switch. This fixes basic usage (e.g. `cc --version`) when AT_EXECPATH isn't present on older branches (e.g. under emu-user-static, at the moment), where we would previously run off the end of ::environ.

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
