[PATCH] D152798: [AMDGPU][ValueTracking] Handle amdgcn intrinsics that cannot create poison

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

The nice thing to do would be to route this through a TTI hook.

Also I would argue that no target intrinsics can produce poison. Arithmetic poison ultimately exists because of the desire to tolerate different edge case handling on different targets, but target instructions should be well defined
