	* recog.c (store_data_bypass_p): Add support to allow IN_INSN to
	be a PARALLEL containing sets.  Return false when out_pat is not
	a PARALLEL insn.
	* configure.ac: Add test for mf{t,f}gpr instructions.

	(PROCESSOR_DEFAULT64): Likewise.
	* config/rs6000/rs6000.md (define_attr "type"): Add insert_dword,
	shift,trap,var_shift_rotate,cntlz,exts, var_delayed_compare, mffgpr
	and mftgpr attributes.
	(define_attr "cpu"): Add power6.
	Change instruction sequences to use new attributes.
	(floatsidf2,fix_truncdfsi2): use TARGET_MFPGPR.
	(fix_truncdfsi2_internal_mfpgpr): New.
	(floatsidf_ppc64_mfpgpr): New.
	(floatsidf_ppc64): Added !TARGET_MFPGPR condition.
	(movdf_hardfloat64_mfpgpr,movdi_internal64_mfpgpr): New.
	(movdf_hardfloat64): Added !TARGET_MFPGPR condition.
	(movdi_internal64): Added !TARGET_MFPGPR and related conditions.
	* config/rs6000/{6xx.md,power4.md,8540.md,603.md,mpc.md,
	7xx.md,rios2.md,7450.md,440.md,rios1.md,rs64.md,power5.md,40x.md}:
	Add descriptions for insert_dword, shift,trap,var_shift_rotate,
	cntlz,exts and var_delayed_compare.
	* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Define
	_ARCH_PWR6, if features enabled.
	* config/rs6000/rs6000.opt (mmfpgpr): New.

	(cached_can_issue_more): New variable.
	(processor_costs): Add power6_cost.
	(rs6000_sched_init): New function.
	(is_dispatch_slot_restricted): Deleted.
	(set_to_load_agen): New function.
	(is_load_insn,is_store_insn): New functions.
	(adjacent_mem_locations): New function.
	(insn_must_be_first_in_group): New function.
	(insn_must_be_last_in_group): New function.
	(rs6000_sched_reorder): New function.
	(rs6000_sched_reorder2): New function.
	(TARGET_SCHED_INIT,TARGET_SCHED_REORDER,
	TARGET_SCHED_REORDER2): Define.
	(processor_target_table): Use PROCESSOR_POWER6 for power6,
	Add MASK_MFPGPR for power6.
	(POWERPC_MASKS): Add MASK_MFPGPR.
	(rs6000_override_options): Set rs6000_always_hint to false
	for power6.  Set rs6000_align_branch_targets. Replace
	rs6000_sched_groups check with rs6000_align_branch_targets.
	Use PROCESSOR_POWER6.
	(last_scheduled_insn): New variable.
