================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:7987
+      CA, getPointerTy(TD),
+      TD.getPrefTypeAlign(VT.getTypeForEVT(*DAG.getContext())));
+  Align Alignment = cast<ConstantPoolSDNode>(CPIdx)->getAlign();
----------------
The Type for the alignment needs to be the type of the elements in `CA` which is based on what data type is used for the `Table` SmallVector.
