I thought the way Generator worked was that it emulated instructions with C functions (generated at compile time) invoked by a sequence of CALL instructions (in the native processor language.)

It could probably do flag optimization by having different functions for each instruction which calculate different combinations of flags (or none at all.)

I'm not really sure, though. Email James and see what he says :) And then post the answer here ;)
