[PATCH] D139314: ValueTracking: Teach canCreateUndefOrPoison about FP ops

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

Should I mention this doesn't produce poison in LangRef?

I also think it's extremely broken that we have both lround and llround (same with rint). Why isn't this one overloaded intrinsic? Why did it blindly copy the libm's i-don't-know-how-big-integers-are naming?
