================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:1857
   EVT ScalarVT = VecVT.getScalarType();
-  return isOperationLegalOrCustomOrPromote(Opc, ScalarVT);
+  return isOperationLegalOrPromote(Opc, ScalarVT) ||
+         isOperationCustom(Opc, ScalarVT);
----------------
Can we use `isOperationLegalOrCustomOrPromote`?
