[PATCH] D47672: [Headers] Add _Interlocked*_HLEAcquire/_HLERelease

[Hans Wennborg via Phabricator via cfe-commits]

hans added a comment.

It sounds like adding proper support for HLE prefixes is a largeish project.

ctopper, rnk: Do you think it would be worth adding inline asm versions (with the xacquire/release prefixes) of these intrinsics in the meantime? It would inhibit optimizations but be better than the current state of not having the intrinsics at all.
