Confirmed, reduced testcase:
typedef int __m64 __attribute__ ((__vector_size__ (8)));
typedef int __v2si __attribute__ ((__vector_size__ (8)));
static __inline __m64 __attribute__((__always_inline__)) _mm_add_pi32 (__m64 
__m1, __m64 __m2) {
  return (__m64) __builtin_ia32_paddd ((__v2si)__m1, (__v2si)__m2);
};
__m64 simple_block_diff_up_mmx_4(  const int width ,__m64 ref1 ) {
  __m64 sum;
  int count = width >>1;
  while (count--)
    sum = _mm_add_pi32 (sum, ref1);
  return sum;
}
