[PATCH] D54121: [FPEnv] Add constrained FCMP intrinsic

[Cameron McInally via Phabricator via llvm-commits]

cameron.mcinally added a comment.

I'm working on the changes that we discussed, but they're pretty invasive. A prospective patch is coming soon, but I wanted us to start thinking about how we'll handle these intrinsics at the SelectionDAG level. There are no CMP ISD nodes (also, what does legalization look like??), so this will likely be a significant change.
