[PATCH] D43739: [ValueTracking] Teach cannotBeOrderedLessThanZeroImpl to handle vector constants.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I'd like to go ahead and get this in. I have another follow up patch to teach cannotBeOrderedLessThanZeroImpl to walk through ExtractElement too. The original place I saw this was two fabs on elements extracted from a vector.

But I think you're probably right that we should probably improve pattern matching for FP here.
