[PATCH] D128681: [AMDGPU][ScheduleDAG] Check for CopyToReg PhysReg clobbers in pre-RA-sched

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/ScheduleDAGRRList.cpp:1311
+    // Allow multiple uses of same def
+    if (Node && LiveRegDefs[*AliasI]->getNode() == Node)
+      continue;
----------------
Do you really want to insert it if Node is nullptr?
