Description
After #6511 and #7040, rustc is ready to use LLVM completely threadsafely.
All that's missing is to stop passing the --disable-threads
and --disable-pthreads
flags to LLVM's configure script. Once this is done, the lock-enabling code in trans should be uncommented as well.
This is a simple change, but requires the bots to rebuild LLVM (which has caused problems in the past). @brson has some other LLVM patches to integrate, and this would fit nicely with those.
