------- Additional Comments From steven at gcc dot gnu dot org  2005-05-06 08:50 -------
Can someone explain what is expected here?  I get the following .optimized 
dump: 
 
main () 
{ 
  int lsm_tmp.1; 
  int D.1572; 
  int D.1571; 
  int i.0; 
 
<L8>:; 
  lsm_tmp.1 = i; 
  goto <bb 2> (<L10>); 
 
<L9>:; 
 
<L10>:; 
  switch (lsm_tmp.1) 
    { 
      case 0 ... 1: goto <L1>; 
      case 2 ... 3: goto <L13>; 
      case 5: goto <L5>; 
      default : goto <L9>; 
    } 
 
<L1>:; 
  i = lsm_tmp.1; 
  D.1571 = 1; 
  goto <bb 6> (<L7>); 
 
<L5>:; 
  lsm_tmp.1 = 4; 
  goto <bb 1> (<L9>); 
 
<L13>:; 
  i = lsm_tmp.1; 
  D.1571 = 0; 
 
<L7>:; 
  return D.1571; 
 
}
