================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:11201
+bool isVMV_V_X_VLOfConstant(SDValue N, APInt &SplatVal) {
+  auto *C = dyn_cast<ConstantSDNode>(N->getOperand(1));
+  if (C && N.getOpcode() == RISCVISD::VMV_V_X_VL) {
----------------
It may cause assertion error when N has exactly one operand.
