[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUISelDAGToDAG.cpp:1569-1570
                                                   SDValue &Offset) const {
+  if (Subtarget->enableFlatScratch())
+    return false;
