[PATCH] D50913: [FPEnv] Don't need copysign/fabs/fneg constrained intrinsics

[Cameron McInally via Phabricator via llvm-commits]

cameron.mcinally added a comment.

It looks like an explicit FNEG operation isn't going to fly. I propose we drop that pursuit and continue forward with a constrained FNEG intrinsic.

I suppose the best plan of action would be to add constrained COPYSIGN and FABS intrinsics too, so that the whole set is uniform. Does anyone feel strongly otherwise? If not, I'll close this Diff and work on a patch to put them in place.
