Chandler Carruth c6ece6bf3b Disable the use of std::call_once on PowerPC due to an apparent bug in ... libstdc++ (or in compilers, or somewhere, I can't track it down) that causes unittests that use INITIALIZE_PASS to crash. The analysis I've been able to do is that inside libstdc++'s implementation of std::call_once, it uses pthread_once, and when that returns an error code it throws std::system_error which then eventually calls std::terminate. Hopefully some of the folks who work on PPC can try to sort out what's going on here. Until then, they'll have to use the fallback implementation. llvm-svn: 271821		2016-06-05 02:46:01 +00:00
