[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/Target/AMDGPU/AMDGPUAtomicOptimizer.cpp:379
+    BroadcastI = B.CreateBitCast(Insert, Ty);
+  } else if (Ty->getPrimitiveSizeInBits() == 32) {
+    BroadcastI = B.CreateCall(ReadFirstLaneIntrinsic, PHI);
