[PATCH] D129073: [AMDGPU] Combine s_or_saveexec, s_xor instructions.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIOptimizeExecMasking.cpp:830-831
+
+  Changed |= optimizeOrSaveexecXorSequences();
+  Changed |= optimizeVCmpxAndSaveexecSequences();
 
----------------
Why do you need to collect every instance in the function before processing them? Each of these can be handled standalone?
