- Taniwha 6y agowell except for push/pop, and all the microcoded stuff. IMHO the x86 has been successful because it started out semi-RISCy - no indirect addressing modes, no auto inc/dec, only one memory access per instruction - (except for push/pop and the microcoded segment stuff). It means either an instruction goes to completion, or it faults, there's no state change to undo if something takes a TLB miss - compared with a 68k etc it's an easy implementation
