my make.conf contains commented out entries for all cpus i used before. i use '-march' to allow compiler to choose optimal instructions for my cpu.

i think at some point gentoo started to recommend to not use '-O3' but use '-O2', because gcc since some version may generate incorrect code with '-O3'. that was the time i switched to '-O2' but i cannot find the recommendation now to link to it.

i remember when i took out my hard drive on which i compiled gentoo with '-march pentium3' from pentium3 machine and booted a pentium2 machine with it.

i thinx it booted okay, then gnome2 programs and gnome itself were crashing with illegal instruction errors.

Random stupidity — I like to tinker with things. A few months ago I had decided to rebuild most of my system with -Ofast to see what would break. (If anyone's interested, very little breaks right away, but you get a lot of subtle bugs and crashes that show up apparently at random.) Well, I rebuilt *almost* everything with sane CFLAGS, but I missed the qtdeclarative package. I just spent hours trying to analyze why Lagrange kept crashing on my machine whenever I enabled or disabled a certificate...
