[PATCH] D69275: Add constrained int->FP intrinsics

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

kpn updated this revision to Diff 231300.
kpn added a comment.

Update for review comments. Use MERGE_VALUES node. Eliminate hacks to avoid x86 custom lowering. This means more x86 target support.

I have not addressed the algorithm issues pointed out by Ulrich. So far I'm trying to just get the existing algorithms converted for strict use. Would it make sense to hold off on algorithm changes until another patch?
