           Summary: Wrong comment in header
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: minor
          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

Ok, it's not very important, but it's an error. I was reading the file
/usr/lib/gcc-lib/i386-linux/3.3/include/mmintrin.h and I found this little error:

/* Creates a vector of four 16-bit values, all elements containing B.  */
static __inline __m64
_mm_set1_pi8 (char __b)
{
  unsigned int __w = (unsigned char)__b << 8 | (unsigned char)__b;
  unsigned int __i = __w << 16 | __w;
  return _mm_set1_pi32 (__i);
}

I don't think that the comment it's right. The __b gets duplicated in __w, then
__w gets duplicated in __i and get duplicated again in _mm_set1_pi32 . So the
comment should be:

/* Creates a vector of eight 8-bit values, all elements containing B.  */
