- no. both have a register (they actually got 16 or more, but 1 is enough).
- so D0 on 68k, R0 or whatever in PPC. where's the prob ?
-
- the prob is will it be possible to mix 68k and PPC code and how...
-
- I'd compile all for 68k except medium time critical routines, I'd compile
- those for both (if there was an option to execute one of both dependent
- on which cpu you run. if if... all a question of interface, not of
- "is it possible". it is all possible).
-
- more timie critical routines in asm for 68k, mega-time critical
- routines in asm for both cpus.
-
- : result in some PPC register, it will not have to be in d0 under 68k emulation when it gets
