[PATCH] D119696: [AMDGPU] Improve v_cmpx usage on GFX10.3.

[Thomas Symalla via Phabricator via llvm-commits]

tsymalla added a comment.

It would probably make sense to only insert the pattern if Exec is not only not written but not implicitly used by a VALU instruction between the cmp and the saveexec - otherwise, the VALU will be executed with the wrong exec mask.
