[PATCH] D60834: [AMDGPU] Uniform values being used outside loop marked non-divergent

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/Target/AMDGPU/AMDGPUISelDAGToDAG.cpp:92
+    // inside the loop but is non-uniform for uses outside the loop, without
+    // it here ISel doesn't get this information from DA
+    AU.addRequiredID(LCSSAID);
----------------
A little more about why it doesn’t get this information would be good
