    Changing compiler optimization

    Does anyone know what optimization (if any) the compiler performs, or if it's possible to change it?

    I know that gcc itself supports different levels of optimization with the -On flag, but is it possible to do this when compiling for target phones to make it optimise for speed (loop unrolling, etc) ?

    From what I've seen about thi subject it seems that it's not a good idea to try this. Appaently the branched version of GCC used by Symbian doesn't do optimisations properly, and can cause problems. It's a shame as it means all Symbian apps are underperforming in terms of size and speed.
