[PATCH] D52416: Allow FP types for atomicrmw xchg

[Alex Bradbury via Phabricator via llvm-commits]

asb added reviewers: asb, jyknight.
asb added a comment.

I should probably plan to reflect support for this in my in-flight cmpxchg patch (which adds target-independent support for late lowering of cmpxchg in the same way I added it for atomicrmw). [incidentally - reviews on that patch would be very welcome...]

Adding James Y Knight as a reviewer here too.
