Hi,

I have added some ARM assembler routines to the FPC RTL for division and string operations. This should speed up some things on GP2X, GBA and NDS (allthough the latter 2 already can do division through the BIOS).

Just seen on svn and... WOW!


+ Assembler implementation of mod/div.
Improves amount of divides from about 230000/s to about 2400000/s on
ARM920T, 200MHz.

I guess you've made these benchmarks on your brand-new GP2X :D

However, that's just great for NDS too, because only GBA uses bios funcs

Yes, indeed. By the way, the GP2X emulates the GBA rather well, so I am playing a bit with FPC4GBA these days too.

Any way I could get going on FPC for Gp2x? I *love* optimizing routines :)
