[LLVMdev] AsmParser for backend

[Jonathan]

Hi,

I try to create a backend to support AsmParser, but it hasn't the red part as below. I find the Mips has this. Do you know how to make it appear?

  void convertToMCInst(unsigned Kind, MCInst &Inst, unsigned Opcode,
                       const SmallVectorImpl<MCParsedAsmOperand*> &Operands);

                                unsigned VariantID = 0);

  enum OperandMatchResultTy {
    MatchOperand_Success,    // operand matched successfully
    MatchOperand_NoMatch,    // operand did not match
    MatchOperand_ParseFail   // operand matched but had errors
  };
  OperandMatchResultTy MatchOperandParserImpl(
    SmallVectorImpl<MCParsedAsmOperand*> &Operands,
    StringRef Mnemonic);
  OperandMatchResultTy tryCustomParseOperand(
    SmallVectorImpl<MCParsedAsmOperand*> &Operands,
    unsigned MCK);

#endif // GET_ASSEMBLER_HEADER_INFO
