Add Niagara-2 support. 

2007-10-18  David S. Miller  <davem@davemloft.net>

	Add Niagara-2 support.
	* doc/invoke.texi: Document -m{cpu,tune}=niagara2.
	* config.gcc: Add niagara2 to cpu and tune lists for sparc.
	* config/sparc/sparc.md (sparc_cpu_attr): Add niagara2.
	(include): Add inclusion of niagara2.md
	* config/sparc/sparc.c (niagara2_costs): New.
	(sparc_override_options): Add niagara2 entry to cpu_default[]
	and cpu_table[].  Set align_functions to 32 on Niagara2.  Use
	niagara2_costs when PROCESSOR_NIAGARA2.  Handle Niagara2 for
	PARAM_SIMULTANEOUS_PREFETCHES and PARAM_L1_CACHE_LINE_SIZE.
	(sparc_initialize_trampoline): Handle niagara2 like niagara.
	(sparc64_initialize_trampoline): Likewise.
	(sparc_use_sched_lookahead): Likewise.
	(sparc_issue_rate): Likewise.
	* config/sparc/sol2-bi.h: Handle TARGET_CPU_niagara2 and
	mcpu=niagara2
	* config/sparc/sparc.h (TARGET_CPU_niagara2): Define.
	({CPP,ASM}_CPU64_DEFAULT_SPEC): Set appropriately for
	TARGET_CPU_niagara2.
	(PROCESSOR_NIAGARA2): New.
	(REGISTER_MOVE_COST): Handle PROCESSOR_NIAGARA2.
	(BRANCH_COST): Likewise.
	* config/sparc/linux64.h: Handle TARGET_CPU_niagara2.
	* config/sparc/sol2.h: Likewise.
