[PATCH] D53157: Teach the IRBuilder about constrained fadd and friends

[Kevin P. Neal via Phabricator via cfe-commits]

kpn updated this revision to Diff 207829.
kpn added a comment.

I was convinced in email that having the constrained intrinsics take fast math flags could be useful in some circumstances. The example that was given was that perhaps FMA contraction could be requested. So, when generating constrained intrinsics the fast math flags and the FP metadata is now handled exactly the same as in non-constrained mode. I've updated the documentation to warn about that when turning constrained mode on and off.

I was also a little worried about having CreateConstrainedFPBinOp() handle fast math flags differently from CreateBinOp(). Now they're the same.
