This makes no sense:



static void

mn10300_scan_for_setlb_lcc (void)

{

  struct loops loops;

  loop_iterator liter;

  loop_p loop;



  DUMP ("Looking for loops that can use the SETLB insn", NULL_RTX);



  df_analyze ();

  compute_bb_for_insn ();



  /* Find the loops.  */

  if (flow_loops_find (& loops) < 1)

    DUMP ("No loops found", NULL_RTX);

  current_loops = & loops;



Note the uses of "loops".



Joern, I think you need to look at this a little deeper to see what's really

happening.
