[PATCH] D107859: [AMDGPU] MachineLICM cannot hoist VALU

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

This might be a silly question but I have to ask it: why do we have implicit uses of exec in the first place, if we have to keep teaching passes to ignore them? (Maybe we could only add the implicit uses later in the pass pipeline, which control flow intrinsics are lowered to explicit exec mask manipulations?)
