[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: lib/Target/AMDGPU/SIPeepholeSDWA.cpp:910
+  MachineInstr *MICI = MRI->getUniqueVRegDef(CarryIn->getReg());
+  if (MICI != &MI)
+    return;
----------------
This check is not needed. findSingleRegUse() already did it.
