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.
