[PATCH] D144162: [AMDGPU] Replace LegacyDA with Uniformity Analysis in AnnotateUniformValues

[Sameer Sahasrabuddhe via Phabricator via llvm-commits]

sameerds added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUAnnotateUniformValues.cpp:81
 void AMDGPUAnnotateUniformValues::visitBranchInst(BranchInst &I) {
-  if (DA->isUniform(&I))
+  if (!UA->hasDivergentTerminator(*I.getParent()))
     setUniformMetadata(&I);
----------------
I am not sure we should be doing this. Smells like a bug in the UA!
