[PATCH] D104408: AMDGPU/GlobalISel: Treat undef as KnownNeverNaN

[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic added a comment.

This is required to match splat that was padded with undef into clamp D90052 <https://reviews.llvm.org/D90052>. When undef is used to pad with element that does not affect the result we interpret it in a way to clamp other elements.
