>Description:
Compiling fpxor.c without optimization produces:
$ gcc -g -msse -o fpxor fpxor.c
fpxor.c: In function `main':
fpxor.c:12: Internal compiler error in emit_move_insn, at expr.c:2746
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
>How-To-Repeat:
Compile this code (fpxor.c) without -O:
#include <xmmintrin.h>
int main( argc, argv )
int argc;
char **argv;
/*
gcc -g -msse -o fpxor fpxor.c
*/
{
static __m128 from1, from2, to;
to = _mm_xor_ps( from1, from2 );
exit( 0 );
}
>Fix:
Compile with -O1 or -O2 or -O3
