================
Comment at: llvm/lib/Target/X86/AsmParser/X86AsmParser.cpp:3927-3928
+  if ((Opcode == X86::PREFETCHIT0 || Opcode == X86::PREFETCHIT1)) {
+    for (unsigned i = 0; i < Inst.getNumOperands(); i++) {
+      const MCOperand &MO = Inst.getOperand(i);
+      if (!MO.isReg() || MO.getReg() == X86::NoRegister)
----------------
How about `Inst.getOperand(X86::AddrBaseReg)`?
