Hi All, The landed patch https://reviews.llvm.org/D38481 introduced the usage of CPU_COUNT defined in glibc sched.h header. I failed to find this symbol in sched.h of glibc version 2.5-24, so compilation just fails. /home/dolphin/merge-from-upstream-area/ws/pristine/lib/Support/Threading.cpp: In function 'unsigned int llvm::hardware_concurrency()'...

...his breaks at least on Centos 6.4 which is derived from REHL 6. This appears to break on anything REHL 6 (or earlier) derived. I think this patch needs to be reverted. Thoughts?
