[PATCH] D149587: InstSimplify: Simplifications for ldexp

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

Drop dead code, add strictfp and FMF todo. I looked into merging with simplifyFPOp, but it would multiply the complexity of the patch. I also don't necessarily agree we have adequate information to fold these given denormal input exceptions exist and the denormal mode is dynamically changeable
