it seems a bit different from what I use in nebulam2, it seems that it generates a func for each instruction variation (register and flags), while for m2 I only generate 1 variation, and use a struct to hold the pointers to the src and dst operands, that requires extra work on decoding, I don't know if it's faster or slower.

I should work some day on making the DSP alu ops not to compute the flags always, actually the code to compute flags is twice as big as the code to just compute the result (that will be a very nice speedup).
