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. -- Groeten, Michel. http://www.cs.vu.nl/~mdruiter \----/==\----/ \ / \ / "You know, Beavis, you need things that suck, \/ \/ to have things that are cool", Butt-Head.
