Could you please explain why -Os instead of -O2 or -O3 ?? that's really puzzling me.
...-Os is the apple recommended optimization, which I've been using lately (but haven't really done any testing vs. -O3)...basically keeps code small while doing -O2+ levels of optimization, which I think is a win for ppc's...I need to start playing with adding in the auto-vectorization, see if we get any wins there...
