andrew.w.kaylor added a comment.

To clarify, I was suggesting a single intrinsic with quiet/signaling encoded in the predicate. I think the IR definition is a bit cleaner this way and it maps to both the IEEE specification and at least the most common way (I think) this is implemented in x86 hardware and probably others. That said, if doing it this way makes the implementation more complicated I could go along with separate intrinsics and ISD opcodes.
