    Let me be more clear. My program has to run on every Palm OS <5 and
every device. Are there some instructions which I can use to accelerate on
m515 for example? If they are, I can use conditions (if's) to specify the
correct instruction set to use on every CPU class.

All of the DragonBall 68K CPUs have the same 68000-based core. There are no instruction sequences that will optimize things for a particular DragonBall CPU.


Since 68K code is emulated on the ARM-based devices, optimizing that code to run as fast as possible on the real 68K-devices is the best move there, with a possible bias towards having fewer instructions, since there is emulation overhead per instruction fetch.
