================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:7986
+  return DAG.getLoad(
+      VT, dl, DAG.getEntryNode(), DAG.getMemBasePlusOffset(CPIdx, Lookup, dl),
+      MachinePointerInfo::getConstantPool(DAG.getMachineFunction()), Alignment);
----------------
`Lookup` needs a sextOrTrunc to the target's pointer type.
