Hi,

When I installed a new version of Portage, I noticed the pentium4 flag is
not used anymore in make.conf. Now I wondered if I had to reinstall
everything

I tried a test (which was mentioned in the Gentoo weekly newsletter), and
my machine passed. The test can be found here:

http://article.gmane.org/gmane.linux.gentoo.user/44339

Does this mean everything is ok? Or only my python?

My CFLAGS were:

CFLAGS="-O3 -march=pentium4 -funroll-loops -fprefetch-loop-arrays -pipe"

My gcc version is:

gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r1, propolice)

Thanks in advance!

I'm not sure if the sse2 instruction issues were fixed in 3.2.3.
I'm fairly certain they're fixed in 3.3.x.

I'd say that if it ain't broken, don't fix it.
