[PATCH] D118975: [AMDGPU] Allow hoisting of some VALU compare instructions

[Nicolai Hähnle via Phabricator via llvm-commits]

nhaehnle added a comment.

I suspect that V_CNDMASK uses are fairly common, and those implicitly mask with EXEC as well.

This also doesn't address more complex cases like

  %0 = V_CMP ...
  %1 = V_CMP ...
  %2 = S_OR %0, %1
  V_CNDMASK lhs, rhs, %2

though perhaps the change is good as-is for now.
