           Summary: illegal instruction in _mm_add_si64
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ottavio at campana dot vi dot it
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i386-linux
  GCC host triplet: i386-linux
GCC target triplet: i386-linux

This code get executed but doesn't work, because I get illegal instruction when
it executes the last mmx instruction

#include <mmintrin.h>

int main(void) {
        __m64 temp, soglie_minime;
        unsigned char rossomin = 1;
        unsigned char verdemin = 2;
        unsigned char blumin = 2;
        unsigned char rossomax = 3;
        unsigned char verdemax = 4;
        unsigned char blumax = 5;

        temp = _mm_cvtsi32_si64 ( (unsigned int) (blumin << 16) + (verdemin <<
8) + rossomin);
        soglie_minime = _mm_slli_si64 (temp, 32);
        soglie_minime = _mm_add_si64 (temp, soglie_minime);

        return 0;
}

I compile it with "gcc-3.3 -mmmx test.c -o test".

If I compile it with "gcc-3.3 -O3 -mmmx test.c -o test" it works, but if I used
the same compiling options and put the 3 mmx instructions in a shared object I
always get illegal instruction.
