Glibc 2.10 compiled fine for me. I have 4.4 with graphite enabled, and the graphite-specific flags in my CFLAGS (though I haven't investigated; the glibc build process may disable them).

Recompiled the webserver using gcc-4.4.0 (graphite enabled, cflags on) and glibc-2.10.1 last night.
These are the packages that ran into trouble:
app-portage/eix-0.16.0
sys-fs/reiser4progs-1.0.6
x11-misc/xosview-1.8.3
app-arch/arj-3.10.22-r2
net-misc/openswan-2.4.14

Otherwise everything else is working fine, apache, php, mysql, ssh, pure-ftpd, postfix among others.

EDIT: Most of these seem to be glibc-2.10-related, some have already been fixed.

Many of those have built successfully on my system using gcc-4.4.0, so your problems must be either graphite or glibc-2.10.1 related.

i rebuilt my system at home with gcc-4.4 ( but without all the -floop-stuff) and all went fine. This is a minimal setup so this was expected i guess.
Will now rebuild some stuff with the -floop-* flags and see what happens, hopefully there is some noticeable improvement.

One thing i didn´t realize till now is that since gcc-4.3.2-r3 gcc itself gets compiled MUCH faster, all my cores are used now.
gcc-4.3.2 took about two hours, >=gcc-4.3.2-r3 took 20 minutes !

cheers

wow...
Just wow.

I have been running a complete glibc-2.10-based gcc-4.4(graphite+flags)-compiled system on my webserver for a couple of days now, and I would say that I am experiencing a _significant_ performance upgrade!
This has even been confirmed by three people I host sites for who have contacted me and complemented on the percieved increase in speed.
Things are looking very good so far :)

No, octave 3.0.3 fails because of gcc-4.4. There is an open bug in the bugzilla with the 3.0.5 ebuild, which compiles and works fine with gcc-4.4 and glibc-2.10.1, but the responsible dev is taking his time (the ebuild has been sitting in the bugzilla for almost two months).

Very nice to see some real life performance improvements as well, not just static tests :)

Is there another source to pull the phoronix packages from? Downloading takes f-o-r-e-v-e-r.

Nvm, speed took up after a while, and I'm now running the tests.

Can you show your flags? What I need to use graphite? Graphite in use + -fgraphite in cflags?

emerge it with the graphite use-flag

here some info:
Quote:
The Graphite branch has been merged. This merge has brought in a new framework for loop optimizations based on a polyhedral intermediate representation. These optimizations apply to all the languages supported by GCC. The following new code transformations are available in GCC 4.4:

-floop-interchange performs loop interchange transformations on loops. Interchanging two nested loops switches the inner and outer loops. For example, given a loop like:
DO J = 1, M
DO I = 1, N
A(J, I) = A(J, I) * C
ENDDO
ENDDO

loop interchange will transform the loop as if the user had written:

DO I = 1, N
DO J = 1, M
A(J, I) = A(J, I) * C
ENDDO
ENDDO

which can be beneficial when N is larger than the caches, because in Fortran, the elements of an array are stored in memory contiguously by column, and the original loop iterates over rows, potentially creating at each access a cache miss.

-floop-strip-mine performs loop strip mining transformations on loops. Strip mining splits a loop into two nested loops. The outer loop has strides equal to the strip size and the inner loop has strides of the original loop within a strip. For example, given a loop like:
DO I = 1, N
A(I) = A(I) + C
ENDDO

loop strip mining will transform the loop as if the user had written:

DO II = 1, N, 4
DO I = II, min (II + 3, N)
A(I) = A(I) + C
ENDDO
ENDDO

-floop-block performs loop blocking transformations on loops. Blocking strip mines each loop in the loop nest such that the memory accesses of the element loops fit inside caches. For example, given a loop like:
DO I = 1, N
DO J = 1, M
A(J, I) = B(I) + C(J)
ENDDO
ENDDO

loop blocking will transform the loop as if the user had written:

DO II = 1, N, 64
DO JJ = 1, M, 64
DO I = II, min (II + 63, N)
DO J = JJ, min (JJ + 63, M)
A(J, I) = B(I) + C(J)
ENDDO
ENDDO
ENDDO
ENDDO

which can be beneficial when M is larger than the caches, because the innermost loop will iterate over a smaller amount of data that can be kept in the caches.

Okie dokie.

I have fully built my laptop with the gcc 4.4 toolchain on ~amd64, and it is working fine. There are qualitative feelings of a speed increase, but then again I did end up reinstalling [NEVER unmerge python, even if there are 5 copies of it] and using a mature set of use flags so I'm not sure what it is due to.

Given there have been claims of speed improvements with glibc 2.10.1, I'm going to take that plunge. The laptop needs all the help it can get - poor little Dell D430. I make it do so much with so little...

I've finally done some of the phoronix tests that was mentioned previously. I've been having some problems with the games, but I hope I've got "enough"
What do I do with them now? Would anyone care to take a look and let me know if I've missed anything important before I upgrade to 4.4?

Recompiled the AMD64 laptop with GCC-4.4.0 from portage, including:

Code:

CFLAGS="-O2 -march=native -ftree-vectorize -floop-interchange -floop-strip-mine -floop-block -fomit-frame-pointer -pipe"                                                             
CXXFLAGS="${CFLAGS}"
CPPFLAGS="${CFLAGS}"
LDFLAGS="-Wl,-O1 -Wl,--as-needed"


Had the following problems with the given solutions

    net-wireless/wpa_supplicant-0.6.4 (upgrade to 0.6.9)
    media-sound/wavpack-4.50.1 (upgrade to -r1)
    media-libs/libopenraw-0.0.5 (upgrade to 0.0.7)
    sci-libs/cln-1.2.2 (patch from b.g.o)
    app-crypt/qca-ossl-2.0.0_beta3 (upgrade to -r1)
    media-gfx/hugin (patch from b.g.o)
    net-libs/xulrunner-1.8.1.19 (patch from b.g.o)


Which just leaves

    dev-db/mysql-community-5.0.77-r1
    dev-java/gnu-classpath-0.97-r1


Even openoffice compiled, which was a surprise.

I've had an issue compiling latest webkit-gtk with GCC 4.4.x due to some extraneous text in /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.1-pre9999/include/g++-v4/x86_64-pc-linux-gnu/bits/c++config.h
I changed this:
Code:
#define __GLIBCXX__ built 20090526
to this:
Code:
#define __GLIBCXX__ 20090526
and the problem was solved.

Any app that checks the value of __GLIBCXX__ (there are few, but both webkit and boost do) will probably trigger this bug. __GLIBCXX__ is supposed to be defined as an ISO date.

robnotts: remove -fomit-frame-pointer from cflags, -Ox including it.


Yeah aware of that, just force of habit to have it included, from the days when it wasn't!
Been on gentoo for a long long time!

I've had an issue compiling latest webkit-gtk with GCC 4.4.x due to some extraneous text in /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.1-pre9999/include/g++-v4/x86_64-pc-linux-gnu/bits/c++config.h
I changed this:
Code:
#define __GLIBCXX__ built 20090526
to this:
Code:
#define __GLIBCXX__ 20090526
and the problem was solved.

Any app that checks the value of __GLIBCXX__ (there are few, but both webkit and boost do) will probably trigger this bug. __GLIBCXX__ is supposed to be defined as an ISO date.


stupid :?

thanks for catching that bugger :)
