: Of course, it's documented.  Here's a fragment from gcc's Info docs:
:   `-O3'
:        Optimize yet more.  `-O3' turns on all optimizations specified by
:        `-O2' and also turns on the `inline-functions' option.

Yes, I knew this. But it doesn't say it is the *only* difference, does
it? It explains that -O3 turns on all optimizations specified by -O2,
and that it also turns on the -finline-functions option, but it might
not be the only difference. Or am I being too suspicious?

I guess we have to look at the sources to be sure.
