[PATCH] D43142: Experimental pass to convert all floating point operations to the equivalent constrained intrinsics

[Cameron McInally via Phabricator via llvm-commits]

cameron.mcinally added a comment.

I don't think this will work. The ConstantFolder could fold away traps early in the IRBuilder. We also wouldn't catch the FNeg/FSub case either.

I think Clang would need to explicitly generate the constrained intrinsics.
