[PATCH] D26930: Teach optimizer that pthread_self does not trap. It can be speculatively executed.

[Joerg Sonnenberger via llvm-commits]

joerg added a comment.

Well, readnone functions are safe to speculatively execute. The question is if pthread_self() does qualify for it, since strictly it does read global memory. My problem with this change is that this seems to add a very stricted form of readnone in a non-systematic and adhoc fashion.
