------- Comment #23 from rguenth at gcc dot gnu dot org  2006-04-17 16:54 -------
It also helps for propagating loop versioning guard information like

int foo(int i, int j)
{
  int res = 0;
  if (i==1 && j==2)
    for (;i>0;--i)
      res += j;
  else
    for (;i>0;--i)
      res += j;
  return res;
}
