David Blaikie	41026cffab	Update the non-pthreads fallback for RWMutex on Unix ... Tested this by #if 0'ing out the pthreads implementation, which indicated that this fallback was not currently compiling successfully and applying this patch resolves that. Patch by Andy Chien. llvm-svn: 220969	2014-10-31 17:02:30 +00:00
Mark Seaborn	83fd697a96	Fix RWMutex to be thread-safe when pthread_rwlock is not available ... lib/Support/RWMutex.cpp contains an implementation of RWMutex that uses pthread_rwlock, but when pthread_rwlock is not available (such as under NaCl, when using newlib), it silently falls back to using the no-op definition in lib/Support/Unix/RWMutex.inc, which is not thread-safe. Fix this case to be thread-safe by using a normal mutex. Differential Revision: http://llvm-reviews.chandlerc.com/D2892 llvm-svn: 202570	2014-03-01 04:30:32 +00:00
Charles Davis	e7f14dfdb8	Now to chant the magical incantation that will exorcise the System library ... from LLVM forever: grep -lR "llvm/System" * | grep -v .svn | xargs sed -ie 's#llvm/System#llvm/Support#g' llvm-svn: 120314	2010-11-29 19:44:50 +00:00
