Thank you menschmeier,
I am looking for gcc4 optimisation. It is on Options That Control Optimization
I was allready reading the gentoo wiki, but it is nothing about gcc 4 new use flags, and the link on the forum on that wiki have plenty of flags they can make things faster, but unreliable in some cases.
In the gcc4 manual, we can read: | Quote: | -ftree-vectorize
Perform loop vectorization on trees. |
and nothing more. So it is impossible to know if this option will do any good and if it will be safe. I thing it is because it is no warning of any kind, but it is only what I am thinking.

gentoo-wiki.com is no official source of information and not part of the Gentoo project.
Everything that belongs into the *.gentoo.org domain is official.
As for emerge -e system twice, this makes no sense.

At which time a sticky thread about this will be posted and the gcc upgrade guide is getting a small makeover right now. Once that is done i'll lock this pre-release thread and link to the new sticky one.

Oh, and if you have a nvidia card and reemerge nvidia-glx, kernel or drivers with the new gcc, don't forget to recompile your kernel else the module won't be inserted! |

Since it's official now, please refer to the sticky thread GCC 4.1.1 and glibc 2.4 stable on x86 and amd64 for further questions about the update. I'm locking this one to avoid discussing the same things in different places over and over again.
