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

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

kpn updated this revision to Diff 176432.
kpn added a comment.

I've changed the patch so that calls to CreateFAdd() et al will give you constrained intrinsics if they are enabled. This required adding functions to enable/disable constrained-as-default plus calls to deal with the rounding mode and exception handling for contrained intrinsics.

I've left the independent create constrained functions to make it dead easy to move them out of the header and avoid inlining bloat.

I'm not dealing with any fast math flags or metadata currently. I'm not sure they make sense in a constrained context, or at least I haven't seen anyone argue they must be in place for an initial implementation.
