That seems like a good plan to separate these tasks. I will implement this in
the next patchset. Thank you

Based on the info I have, I think a reasonable approach to integration of this
series would be:
- Add this line in mips-defs.h
#define ASE_MXU 0x02000000
- In main switch, use this segment
if (ctx->insn_flags & ASE_MXU) {
decode_opc_special2_mxu(env, ctx);
} else {
decode_opc_special2_legacy(env, ctx);
}
That way, you would be able to add MXU code without specifying CPU that
supports it. This will enable you to focus on MXU, which is a serieoous task
anyway. Hopefully, a CPU will be added at some later date.
Thanks,
Aleksandar
