As there are known ICEs with the link time optimization code on the test suite, you may want to wait a few weeks.

Any word on the just released gcc-4.4.2? http://gcc.gnu.org/gcc-4.4/

Nothing in portage yet, even masked.

I've been running all my Gentoo systems with gcc-4.4.1 for a while now with no problems (as well as Arch, mandriva cooker, both of which use 4.4.1). Even Pclos recently updated it's toolchain to 4.4.1.

Needless to say, 4.4.1 is no fun anymore- feeling a need to rebuild Gentoo..... :wink:

There is a 4.4.2-pre9999 overlay ebuild at http://gentoo-overlays.zugaina.org/gcc-porting/portage/sys-devel/gcc/

but I'd rather not use that, since 4.4.2 is actually released? Can we adapt the 4.4.1 ebuild in portage?

There, highlighted it for you. I'm sure it won't take long.

EDIT: I've been using 4.4.2_pre9999 for ages, no issues.

EDIT #2: It's no reason to rebuild Gentoo.....

EDIT #3: ...aaand there it is.

Well I think it's time to try new gcc :)

has someone used the new optimized interface that it's include in gcc?

http://gcc.gnu.org/wiki/LinkTimeOptimization#head-3b5b9b55878c408b99dd3c100ac32cae53e01714

I think we need libelf v0.8.12 (with isn't in portage get) and a ussing 4.5.0_pre9999 build after 3-0ct.


Nope, we use elfutils instead. libelf gave us nothing but headaches.

LTO is still severely broken, but you can give it a try if you like to make things explode...

Anyways this probably belongs in a 4.5 thread.

Ah, unsupported software ofc. I was looking in programming for some reason, and then I tried the excellent search function we have available.
