[PATCH] D150438: [LLVM][Uniformity] Improve detection of uniform registers

[Ruiling, Song via Phabricator via llvm-commits]

ruiling added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstructions.td:423
   let hasSideEffects = 1;
+  let IsNeverUniform = 1;
 }
----------------
I think ``SI_IF` and `SI_ELSE` also need this flag being set, but it can be done in a separate change with proper tests.
