Yeah, I'm pretty bad at spotting wrong code generation when the only clue I'm given is "somewhere in the archive, -O3 may be doing the wrong thing." :) If you have specific knowledge that the same code which triggers ICEs on m68k when built with -O3 also causes wrong code generation on i386, please share it so we can warn maintainers. If you mean that there is some other bug in gcc-4.0 which causes wrong code generation when using -O3 in some other circumstances, then that's bad, but I don't see how holding up testing transitions for it is a very effective strategy if we don't even know which code is being built wrong. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world. vorlon@debian.org http://www.debian.org/
