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.
