I renamed the test case gccprob.c and made two binaries and two assembler files:
gcc -Wall -msse -mno-sse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -o gccprob_wno gccprob.c gcc -Wall -msse -mno-sse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -S -o gccprob_wno.s gccprob.c gcc -Wall -msse -msse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -S -o gccprob_nono.s gccprob.c gcc -Wall -msse -msse2 -I. -lm -DSOFT_SSE2 -DEMMSOFTDBG \ -O0 -o gccprob_nono gccprob.c The _wno variants have the problem passing __m128d on the stack, the _nono varients do not. packed up all 5 files and put them here (retrieve only directory, no directory listings in pickup): http://saf.bio.caltech.edu/pub/pickup/gccprob.tar.gz I am not an assembler programmer. If one of you who is could have a look at the two .s files maybe we can get to the bottom of this.
