Subject: Optimisations


Hello,

When browsing through the GCC manual, I noticed that -Ox is only explained
up to -O3.
Recently I downloaded and installed mplayer, which compiled some files with
-O9.

Does anybody know what those other levels of optimisations mean? (what they
implement?)
Or where they are documented?

This might be slightly offtopic, but I just wondered about it.
It might be usefull for some functions that have to run on my board.

Jan
