Palm OS 5.0 codegen

[<Pet...@ot...>]

The recent 'Some underutilized m68k instructions' conversation made me
think of some issues regarding code generation for Palm OS 5.0.

From what I understand, the ARM base 68k emulator has very different
performance characteristics than a real 68000 chip.  Has there been any
thought to generating code specifically targeted at the OS5 emulator?

Specifically, I'm thinking that the emulator probably has a fairly large
instruction dispatch penalty.  Where the 68000 chip often rewards a
compiler for using two small instructions (e.g. addq) I suspect that the
emulator will penalize this.
