[PATCH] D99434: [TSAN] Honor acquire failure mode on AtomicCAS

[Dmitry Vyukov via Phabricator via llvm-commits]

dvyukov added a comment.

Also I wonder if we could first evaluate CAS and then use either mo or fmo accordingly, so that we don't over-synchronize on failure if mo is stronger than fmo.
