Rafael Espindola a72e2a9037 Bring r314809 back. ... But now include a check for CPU_COUNT so we still build on 10 year old versions of glibc. Original message: Use sched_getaffinity instead of std:🧵:hardware_concurrency. The issue with std:🧵:hardware_concurrency is that it forwards to libc and some implementations (like glibc) don't take thread affinity into consideration. With this change a llvm program that can execute in only 2 cores will use 2 threads, even if the machine has 32 cores. This makes benchmarking a lot easier, but should also help if someone doesn't want to use all cores for compilation for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@314931 91177308-0d34-0410-b5e6-96231b3b80d8		2017-10-04 20:27:01 +00:00
