[BusyBox] Why is it so bad...?

[Tom Cameron]

Hello all,
	I was reading through the GCC man page, wondering what horrible
things '-O3' did to code, so as to make most people shy away from it.  I
have compiled kernels and programs with this option (instead of -Os or -O2),
and have had no problems.  What is the difference between these options?
What does -Os do?  Has anyone run any performance/size/stability tests on
each?  anyone have comments?  Let me know please, as this is quite
interesting to me (performance is everything with the project I'm currently
working on).  Thanks in advance!
