[PATCH] D54855: [AMDGPU] An exp must be branched over if exec=0

[Nicolai Hähnle via Phabricator via llvm-commits]

nhaehnle added a comment.

This should already be fixed in trunk. Trunk has a function TII->hasUnwantedEffectsWhenEXECEmpty to cover this, and this patch simply shouldn't apply.

I vaguely recall you complained about those changes I made and backed them out of the Vulkan branch because of some pixel shader case where some bad lowering happened? I don't remember the details right now.
