Model decoder of Core 2/i7 for multipass scheduling.
* config/i386/i386-protos.h (struct ix86_first_cycle_multipass_data_):
New type to hold target-specific data for multipass scheduling.
(TARGET_SCHED_FIRST_CYCLE_MULTIPASS_DATA_T): Define.
* config/i386/i386.c (ia32_multipass_dfa_lookahead): Update for
Core 2/i7.
(core2i7_secondary_decoder_max_insn_size,)
(core2i7_secondary_ifetch_block_size, core2i7_ifetch_block_max_insns):
New static variables.
([const_]ix86_first_cycle_multipass_data_t): New typedefs.
([_]ix86_first_cycle_multipass_data): New static variable.
(core2i7_first_cycle_multipass_init, core2i7_dfa_poast_advance_cycle):
Implement targetm.sched hooks.
(core2i7_first_cycle_multipass_filter_ready_try): New static subroutine
of ...
(core2i7_first_cycle_multipass_{begin, issue, backtrack, end, fini}):
Implement new targetm.sched hooks.
(ix86_sched_init_global, TARGET_SCHED_INIT_GLOBAL): Define
targetm.sched hook to install multipass scheduling hooks on demand.
* doc/tm.texi.in: Document new targetm.sched hooks.
* doc/tm.texi: Regenerate.
* haifa-sched.c (TARGET_SCHED_FIRST_CYCLE_MULTIPASS_DATA_T): Define.
(first_cycle_multipass_data_t): New typedef.
(struct choice_entry: target_data): New field.
(max_issue): Add first_cycle_insn_p parameter. Call new target hooks
to allow target model restrictions not represented in DFA.
(choose_ready, schedule_block): Update.
(sched_extend_ready_list, sched_finish_ready_list): Call new target
hooks to initialize target-specific data for multipass scheduling.
* sched-int.h (max_issue): Update declaration.
* sel-sched.c (choose_best_insn): Update.
* target.def (first_cycle_multipass_{begin, issue, backtrack},)
(first_cycle_multipass_{init, fini}): Define and document new
targetm.sched hooks.
