[PATCH] D116952: [ConstantFolding] Flush folded denormals to zero when using fastmath

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Does "original operation" mean what hardware would do? Not all targets support flushing denormals to zero. Even within X86, SSE can flush denormals to zero, but X87 can't.
