GCC 4.4.0 testing

Early days yet , but perhaps it may be useful to start a thread.....
gcc-4.4 from dirtyepic's overlay ~amd64 2008.0/desktop. gnome/berkano/mozilla overlays
emerge system,world just 9 failures from 550 packages, not too bad

net-nds/openldap-2.3.43-r1
dev-libs/boost-1.35.0-r2
sys-fs/reiser4progs-1.0.6-r2
dev-libs/apr-util-1.3.4
net-libs/xulrunner-1.9.1_beta1-r1
dev-java/antlr-2.7.7
mail-client/mozilla-thunderbird-3.0_alpha2
media-gfx/f-spot-0.4.3.1
app-office/openoffice-3.0.0

Also dev-libs/nspr-4.7.1 looks to compile fine , but as mention in a comment to dirtyepic's planet gentoo post, appears to cause webpages to be misrendered
and screws up nautilus.

sounds interesting

9 failures out of 550 is pretty good (afaik I had much more with gcc-4.3alpha)

seems like gcc-4.4 (beta++) is going to become a very nice release (much better optimization, support for newest processors, openmp 3.0, etc. etc.)

GNU and the GCC team are on the ball!

what have you say about performance? I mean, compiler time and program optimization

Performance is great thanks to the new register allocator (ira).
This is the first time in years that a new gcc release makes programs go faster
instead of slowing everything down further.
Even a kernel compiled with 4.4 feels snappier.

I think I will try it in my "breack me" machine next weekend.

4.4 sounds really promising, I'll be among the early-adopters.

i have made the switch. so far paludis is broken(ok with me).
i haven't done a system upgrade(takes too long).
stuff compiled as the are upgraded are ok for now.
seems faster to me.

cruzki123 · Post by **cruzki123** » Wed Nov 05, 2008 5:35 pm

had anyone put -fgraphite in his CFLAGS?

Or something more sophisticated?

I'm currently rebuilding world. This is a old machine, so I will take 2 days

Something related: We are going to stabilise GCC 4.3.2 as soon as possible. But some packages still need to be fixed ([bug]198121[/bug]) and others need stabilisation ([bug]245160[/bug]). The collection of needed stabilisations is not yet complete, so gather information and file a bug. Thanks.

Well they almost have all P1 regressions then need to drop the 161 count down below 100 before they officially release it. I can't wait for the bad boy

, I know it's too early to even consider it. But I wonder what will be in 4.5.0. I'll probably switch to GCC-4.4.0 when it gets in RC stage for me like I did with 4.3.0

I cant compile kernel 2.6.27 with gcc version 4.4.0-pre9999 built 20081109 (Gentoo SVN ebuild) rev. 141714 ()

Code: Select all

drivers/built-in.o: In function `usb_submit_urb':
(.text+0x149919): undefined reference to `____ilog2_NaN'
make: *** [.tmp_vmlinux1] Error 1

Another my problem is firefox (from source), on some sites i have 5x or more bigger fonts etc. but xulrunner and ff is compiled by 4.3.2.

Any idea?

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36359 (maybe try -Os)

additionally i got a lot of OOMs (for many cpp sources gcc needs more than 2GB mem) and internal compiler errors (compiling kde), so i guess... it's just not ready yet

@ Slashbeast

Also dev-libs/nspr-4.7.1 looks to compile fine , but as mention in a comment to dirtyepic's planet gentoo post, appears to cause webpages to be misrendered

Recompiling with gcc-4.3.2 solved the problem for me

Just to point out: Although I have not read somewhere about it, gcc-4.4 apparently cleaned up even more include files than gcc-4.3 already did. So the failing of package compilation is often actually a bug of the packages (missing includes) and not of gcc-4.4. >=eix-0.15.0 should be fixed.

Just tried the current snapshot with CFLAGS="-O2 -march=core2 -pipe -fomit-frame-pointer -msse4.1 -ftree-vectorize" and consistently got about 10% speed-improvement when encoding with oggenc - not bad I'd say

I have a Fortran code that works just fine with gfortran-4.1.2, and gets the wrong result with gfortran-4.3.2. It also gives the wrong result on a Ubuntu system with gfortran 4.2.4. I'd like to give gfortran-4.4 a try, but don't know how to get it. My thanks for a pointer (and perhaps instructions if the installation procedure is not obvious).

Here's a list of changes in gcc-4.4:

http://gcc.gnu.org/gcc-4.4/changes.html

It mentions Graphite and how to enable it. That said, you may also want to read this thread on the GCC Mailing List:

http://gcc.gnu.org/ml/gcc/2008-10/msg00191.html

The developers were discussing the Graphite options and the possibility of renaming them. I don't know if they ever did or not.
