================
Comment at: lib/Target/X86/X86ISelLowering.cpp:39302
+        OpVT.is128BitVector() &&
+        InVec.getOperand(0).getValueType().is128BitVector()) {
+      unsigned ExtOp = InOpcode == X86ISD::VZEXT ? ISD::ZERO_EXTEND_VECTOR_INREG
----------------
getValueType() -> getSimpleValueType()
