sparc.c (ultra_code_from_mask, [...]): New functions to describe UltraSPARC pipeline exactly to Haifa.
* config/sparc/sparc.c (ultra_code_from_mask,
ultra_cmove_results_ready_p, ultra_fpmode_conflict_exists,
ultra_find_type, ultra_schedule_insn, ultra_flush_pipeline,
ultrasparc_sched_init, ultrasparc_variable_issue,
ultra_rescan_pipeline_state, ultrasparc_sched_reorder): New
functions to describe UltraSPARC pipeline exactly to Haifa.
(ultrasparc_adjust_cost): Indicate IMUL type insns have zero cost,
as there is nothing the scheduler can do about it. Indicate that
REG_DEP_OUTPUT's collide. Fixup formatting.
* config/sparc/sparc.h (RTX_COSTS): Fixup integer multiply and
divide costs on Ultra for DImode.
(MD_SCHED_INIT, MD_SCHED_REORDER, MD_SCHED_VARIABLE_ISSUE):
Define.
* config/sparc/sparc.md (ieu_unnamed function unit): Rename to
ieuN and add call_no_delay_slot to type list.
(cti function unit): New unit for branches on UltraSPARC.
(subx/addx insns): Set type to misc.
(sidi zero/sign extension insns on arch64): Set type to shift.
(sign_extendhidi2_insn): Set type to sload.
