I'm having the same problem.

The culprit is the 'sse' use flag. If you do "USE=-sse" it emerges fine. It
seems as the ebuild activates the 3dnow support when sse is activated, which it
obviously shouldn't do (I believe 3dnow is specific to athlon cpu's).

Got it. In the ebuild the sse use flag enables dynsimd:

>   $(use_enable portaudio) \
>   $(use_enable sse) $(use_enable sse dynsimd) \
>   --with-pic \

But it seems that the ./configure script or whatever isn't detecting the cpu
features correctly for dynsimd to work. It apears to be a recorrent problem.

It is not an ebuild bug per se, but the workaround would be either disable the
sse use flag (loosing the sse optimizations) or removing the dynsimd option
from the ebuild. The last solution apears to be the best, also because
--enable-dynsimd is disabled by default in the configure script.

Either way, it should be reported upstream.

Cheers

However, it compiles just fine with gcc-3.5.x (with the sse flag).

Re-assign wrt Bug 60090.

I'm taking maintainership.

I've added a local useflag cpudetection.
with it enabled, it will test for 3dnow presence in /proc/cpuinfo and enable
dynsimd if it is found.

fixed this for 101.1-r1 and the just added 102.20.

If anyone is interested in creating a patch for this (enclosing the asm
routines with ifdefs, and updating the configure script respectivly) - this
should really be fixed upstream.

in cvs.

This looks like the wrong fix. The point of dynsimd seems to be to detect the
host CPU and automatically select MMX or SSE code for the necessary SIMD
operations. If I'm on the right track, this certainly doesn't require 3dnow.
The current fix masks the problem only as long as you're building on a CPU
without 3dnow, since it just won't enable dynsimd. See bug 153001 for the
underlying problem preventing compilation of the dynsimd code.
