+          while (Val.getValueType() != MemVT &&
+                 Val->getOpcode() == ISD::BITCAST)
+            Val = Val.getOperand(0);
----------------
Val.getOpcode()


================
Comment at: lib/CodeGen/SelectionDAG/DAGCombiner.cpp:12798
+        // peek through bitcasts

+          StVal = StVal.getOperand(0);
----------------
StVal.getOpcode()
