Re: [gentoo-dev] Re: GCC3.1 bootstrap fails

I've managed to get a working system up and running on gcc-3.1. I used the 
1.3-gcc3.1 stage1 tarball with the following optimizations:-
-march=athlon-tbird -mmmx -m3dnow -O3 -pipe (no -fomit-frame-pointer). The 
mmx and 3dnow flags are obviously only cosmetic at this stage but there 
was no problem with -O3.
There was that problem with xfree, which I could solve by using 
-march=i686 -O3 -pipe (again no -fomit-frame-pointer and -O3 caused no 
problems).
Since -fomit-frame-pointer used to work everywhere with gcc-2..95.x, I 
find it somewhat strange that it should b0rk out with gcc-3.1. It's maybe 
because of changes in the compiler itself, or maybe because of the 
software itself - which the earlier compiler let through without any fuss.
The second looks more likely because my regular optimization flags (for 
the system builds as well as world builds) are -march=-athlon-tbird -mmmx 
-m3dnow -O3 -pipe -fomit-frame-pointer and there's absolutely no problem.
I have yet to compile  qt and kde and going by what I've seen about these 
builds vis-a-vis gcc 3.1 I just might have to go easy again on the 
optimization flags a bit (like I did for xfree).
