Could that be? that shouldnt matter as there needs to be a runtime test to choose as originally u ONLY built the routiens - later i made it runtime chosen so sse and mmx are always built on x86, but chosen runtime. somehow the sse check is either just being ignored (weird) or the check is wrong (i just want to check your souce is the same as i have here). ie - does the sse test function use movntq to test as the only sse instruction in evas_common_copy_pixels_rgba_to_rgba_sse() is the MOVE_16DWORDS_MMX2 macro (movq is old fashioned basic mmx and only these 2 instrucitons are used in that macro). so check your evas_cpu.c sse test is the same as mine here - ie it should be testing: movntq_r2m(mm0, blah); it could be the cpu_can_do though... i've made a small change as technically mmx2 and sse come together. :) > Michael > > -- > Michael Jennings (a.k.a.

Line 52 of src/lib/engines/common/evas_cpu.c has:
void
evas_common_cpu_sse_test(void)
{
#ifdef BUILD_SSE
int blah[2500];
prefetch(blah + 1200);
#endif
}
prefetch is defined in src/lib/include/evas_mmx.h as:
#define prefetch(var) \
__asm__ __volatile__ ( \
"prefetchnta (%0) \n" \
: \
: "r" (var) \
);
I only see movntq_r2m being used in
src/lib/engines/common/evas_convert_yuv.c

ok - your evas is not what is in cvs:
void
evas_common_cpu_sse_test(void)
{
#ifdef BUILD_SSE
int blah[16];
movntq_r2m(mm0, blah);
#endif
}
is what's in dev cvs for evas. up to date:
[ 1:31PM ~/C/evas/src/lib/engines/common ] cvs commit
cvs commit: Examining .
[ 1:31PM ~/C/evas/src/lib/engines/common ]
ie - nothing left to commit. that'll be your problem atm :)
