Comment 1 Jakub Jelinek 2011-02-18 13:00:18 UTC 
Confirmed, reduced testcase with -O2 -march=nocona:
int
foo (unsigned char *x, unsigned char *y)
{
  unsigned char a;
  for (a = 0; x < y; x++)
    if (a & 0x80)
      a = (unsigned char) (a << 1) + 1 + *x;
    else
      a = (unsigned char) (a << 1) + *x;
  return a;
}
