================
Comment at: llvm/lib/CodeGen/SelectionDAG/LegalizeVectorTypes.cpp:5798
       N->getConstantOperandVal(2) == 0)
-    return SubVec;
+    return DAG.getNode(ISD::INSERT_SUBVECTOR, SDLoc(N), VT, InVec, SubVec,
+                       N->getOperand(2));
----------------
Given that no other tests have changed, I assume that `getNode` returns `SubVec` if `SubVec.getValueType() == InVec.getValueType()` ?
