(This from listening to the netbsd lits.) Or, as I commented to you a while back (if I remember right) you just put in the right mapping for the in/out class of instructions instead of whatever grossness the ix86 has. e.g. on the ARM, everything is memory mapped, and doesn't need special classes of instructions to handle I/O, so just have it ldrb/strb/ldr/str (in the same order of the quoted list of macros above) and it will DTRT I guess what I'm saying is that yes, its not totally MI, but its probably not as bad as being totally MS (machine specific), either.
