Ah, I see what you are doing now. Hmm, you'd like to generate a mnemonic-ID and its macros for each opcode, wouldn't you? Even though, it seems waste of memory that we have both opcode and mnemonic-ID, can you integrate that? for example, you can use insn->opcode.value instead of checking each opcode bytes.
Thank you,
