setting march=athlon64 sets sse, sse3, mmx and 3dnow so why add them in anyway? Did you get your make.conf off someone?

from the GCC manual:

Quote:

k8, opteron, athlon64, athlon-fx
AMD K8 core based CPUs with x86-64 instruction set support. (This supersets MMX, SSE, SSE2, 3dNOW!, enhanced 3dNOW! and 64-bit instruction set extensions.)

and -mfpmath=sse is implicit when using a x86-64 compiler

Also, -fomit-frame-pointer was useful with 32bit chips but you won't see any befefits with a 64bit one. At best you'll render backtraces difficult to use.

change your CFLAGS to

Code:

CFLAGS="-O2 -march=athlon64 -pipe

Hi, why not use this instead :

Code:

CFLAGS="-O2 -march=native -pipe"

It will detect automagically your CPU arch and it will unleash all the cflags that you need automatically.

Take a look :

Code:

# gcc -### -march=native -E /usr/include/stdlib.h 2>&1 | grep "/usr/libexec/gcc/.*cc1"

The result is this :
"/usr/libexec/gcc/x86_64-pc-linux-gnu/4.3.4/cc1" "-E" "-quiet" "/usr/include/stdlib.h" "-D_FORTIFY_SOURCE=2" "-march=core2" "-mcx16" "-msahf" "--param" "l1-cache-size=32" "--param" "l1-cache-line-size=64" "-mtune=core2"

So by default it use core2 arch mcx16,msahf and other stuff.

However, it's incompatible with distcc.

It depends, if the other box use the same arch, then yes and if not, you should stick with a i686 arch.

@yngwin, 2 quick question,

what does the -w in your cflags ?

And why use this line :

Code:

EMERGE_DEFAULT_OPTS="--verbose --jobs=3 --keep-going --load-average=6"

Instead of :

Code:

EMERGE_DEFAULT_OPTS="--verbose --jobs=3 --keep-going --load-average=3"

I tought that the jobs param should be equal to the load-average param ?
