[PATCH] D23020: [ValueTracking] bitreverse, sin, cos are safe to speculatively execute

[Matt Arsenault via llvm-commits]

arsenm added a comment.

Needs tests. Bitreverse is definitely OK, but I'm not sure about sin/cos. The math function handling is a mess and they might need to be assumed to set errno (although I don't see why this is the case since the libcall can work for targets with this problem)
