[PATCH] D32782: Add pthread_self function prototype and make it speculatable.

[Joerg Sonnenberger via Phabricator via llvm-commits]

joerg added a comment.

Strictly speaking, the glibc attribute violates the specification of const. I.e. we could turn a call for pthread_self() into a once() initialised static variable and that transform would be valid under the const rules. That clearly doesn't reflect the intention...

That said, I do believe it is fully reasonable to make pthread_self() speculatible by default as long as it can be turned off and is properly documented.
