Well I put the wrong dump in here before, here is the right one:
do_integer_bitwise (iterations, r)
{
  int s.3;
  int s;

<bb 0>:
  s = (int)iterations;
  r = s ^ r;
  s.3 = s ^ r;
  r = s ^ (r | s.3);
  s.3 = s.3 ^ r;
  r = s ^ (r | s.3);
  s.3 = s.3 ^ r;
  r = s ^ (r | s.3);
  return r | s.3 ^ r;

}
