Hello,

I've tried to complile the attached kernel_build.ii on my SUSE SLES 10 x86_64
machine, but got a bunch of compile errors like this:

In file included from /usr/lib/gcc/i486-linux-gnu/4.3.1/include/xmmintrin.h:40,
                 from source/dsp/simd_sse.hpp:24,
                 from source/dsp/arithmetic_wrapper.hpp:32,
                 from source/kernel/audio_backend/audio_backend.hpp:35,

                 from
/home/tim/workspace/nova/release/kernel/audio_backend/build.cpp:2,
                 from release/kernel/kernel_build.cpp:2:
/usr/lib/gcc/i486-linux-gnu/4.3.1/include/mmintrin.h: In function

__vector__)’:

вЂlong long int’ to вЂlong long int
__vector__’ for argument вЂ1’ to
вЂlong long int __vector__ __builtin_ia32_paddq(long long int
__vector__, long long int __vector__)’


Anyway. I see that recently were fixed some problems related to stack alignment
like PR35496. Can you try to compile your example with latest gcc 4.4 compiler
from mainline?
