...-Os is preferred for optimized builds over -O2 or -O3,
Why? the GCC manual says that -Os is for "optimising for size", which isn't exactly optimising for speed. If code size has such a positive impact on speed, does that mean that the PowerPC caches are small and/or the bus of the main RAM is slow ?
Btw, -Os disables most alignment optimisations. I thought that most processors are quite sensitive to alignment; is that belief outdated?
