craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:1858
+  return isOperationLegalOrCustomOrPromote(Opc, ScalarVT) ||
+         isOperationCustom(Opc, ScalarVT);
 }
----------------
Do we still need the `|| isOperationCustom(Opc, ScalarVT)`?
