I don't think that will be much of an issue. There are a few cases in which CF is different from classic 68k (try comparing the address register indirect with postincrement or predecrement addressing modes on CF and classic 68k for A7, if you want a very nice example); but such issues can be worked around by either not using them at all, or just by using them only in certain circumstances (though I don't think that will be possible for the above example). It will just boil down to making sure the compiler does that, and to making sure the assembler refuses to create opcodes that behave too differently on both architectures; this is much easier to accomplish than trying to avoid that the compiler makes mistakes in the optimizer, like it currently does. -- Fun will now commence -- Seven Of Nine, "Ashes to Ashes", stardate 53679.4 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
