2007-06-20 Seongbae Park <seongbae.park@gmail.com>
Maxim Kuvyrkov <mkuvyrkov@ispras.ru>
* dbgcnt.def (global_alloc_at_func, global_alloc_at_reg):
New counters.
* haifa-sched.c (queue_to_ready): Don't requeue next insn
if dbg_cnt (sched_insn) reaches the limit.
(choose_ready): New parameter INSN_PTR and new return value.
(schedule_block): Handle dbg_cnt (sched_insn). Handle
the new return value from choose_ready.
* global.c (global_aloc): New dbgcnt global_alloc_at_reg.
(rest_of_handle_global_alloc): New global_alloc_at_func.
