That's not true. Yes, -Os stands for size. However code size _can_
translate to performance increase. Think about cache footprint, etc.
Smaller code means more can fit in the cache. It also results in a
smaller DRAM footprint for thinks like shared libraries, etc.
Yes. In fact, -Os has been shown in many benchmarks to be just as good
if not occasionally superior in efficiency to -O2.
