That's very inefficient, there are better ways...
Thanks for having a look at it. The Problem is that i also can't use '/', otherwise it wants to link to __aeabi_uidiv . That leads to some Problems, so i'll try to find some better math solution and if that fails i maybe try it the assembler way...
modulo would be "%" btw,
return a%b;
but this might generate external functions too... hmm, try -Os as option?
Ciao, Marcus
% and / both lead to external dependencies here... maybe the euclidean algorithm helps, because -Os would need ugly changes to configure i guess.
