Cool Any Distro with GCC 4.5 ?

Hello and good morning to everybody!

I am interested to GCC 4.5 (still in development) because it has the possibility to optimize code for the Intel Atom CPU (-march=atom -mtune=atom).
This option, together with the last kernel source (that has Atom specific option as well)should be able to produce a pretty optimized Kernel for my Acer One!

Is there any bleeding edge distro that ships with the development version of GCC 4.5?
Or any diistro where the installation of 4.5 would be easy enough?

There is a snapshot of Gcc 4.5 at this link:

I have installed Slackware 13 at the moment, and i intend to stick with it, but i was thinking that i could use another more "bleeding edge" distro to compile an Atom optimized kernel..

Gentoo or Funtoo has a gcc-overlay development branch. Where you can test the latest 4.5 branch. The nice thing is that Gentoo comes with an eclass called gcc-config, It allows for you to switch between multiple gcc compilers. This is handy when you compile legacy code, or trying out some new CFLAGS... like the -march=atom

Thank You,
i was actually able to compile and install GCC 4.5 on slackware 13 and it seems to work well, i just recompiled my kernel with it.
GCC 4.5 is installed on /usr/local/bin, while the normal GCC 4.3 is in /usr/bin, so i have both.


atom, gcc, kernel, optimize
