 The regression show up with this patch:
 
 Sat Jun 23 01:23:59 CEST 2001  Jan Hubicka  <jh@suse.cz>
 
       * flow.c (mark_set_1, attempt_auto_inc, mark_used_reg,
       try_pre_increment_1): compute REG_FREQ using bb->frequency.
 
       * regclass.c (loop_cost): Kill.
       (frequency): New global variable.
       (record_operand_costs): Replace loop_cost by frequency.
       (scan_one_insn): Likewise.
       (regclass): Likewise; set frequency according to bb->frequency.
 
       * flow.c (split_edge): Set frequency.
