	* tree-pass.h: Added pass to clear other dataflow infomation out.
	* final.c (rest_of_handle_final, rest_of_clean_state): Cleared out
	references to df.
	(rest_of_clean_state) Added regstack_completed.
	* reorg.c (fill_simple_delay_slots, fill_slots_from_thread,
	fill_eager_delay_slots, make_return_insns): Added df parameter to function.
	(make_return_insns, dbr_schedule) Added df parameter to calls.
	* flow.c (update_life_info): Added glue code to df calls.
	* df-scan.c (df_scan_free_internal, df_insn_refs_delete, df_ref_record): Added
	code to properly handle multiword hard registers.
	(df_ref_create_structure, df_ref_record): Added code to properly handle subregs.
	(df_ref_create_structure): Changed switching structure. 
	(df_bb_refs_record): Fixed case where duplicate artificial refs
	were created.
	(df_record_entry_block_defs): Added code to make stack pointer
	live in entry block.  Refined cases where frame pointer is needed.
	* df-core.c (df_mvs_dump, clear_df): New function.
	(pass_clear_df): New pass structure.
	(df_insn_uid_debug, df_ref_debug, debug_df_defno, debug_df_ref,
	debug_df_chain): Improved debugging output.
	* df.h: Some reordering to remove forward reference.
	(df_ref_flags.DF_REF_MW_HARDREG, DF_REF_PARTIAL): New fields.
	(df_ref_flags.DF_REF_DIES_AFTER_THIS_USE): Removed.
	(df_mw_hardreg): New struct.
	(DF_INSN_UID_MWS): New macro.
	(df_refs_chain_dump, df_ref_debug, df_chain_dump): Removed df
	parameter.
	* rtl.h (regstack_completed): New global var.
	* resource.c (mark_target_live_regs): Added passed in instance of
	df.
	* resource.h (mark_target_live_regs): Ditto.
	* df-problems.c (df_chain_dump): Removed df parameter.
        (df_ru_bb_local_compute_process_def,
	df_rd_bb_local_compute_process_def, df_lr_bb_local_compute,
	df_lr_bb_local_compute, df_chain_create_bb): Made subreg aware.
	(df_ru_bb_local_compute, df_rd_bb_local_compute,
	df_lr_bb_local_compute, df_lr_bb_local_compute,
	df_chain_create_bb): Cleanup to use proper macros.
	(df_ur_local_finalize, df_ur_local_finalize): Removed unnecessary
	code to fixup bitvectors.
	(df_ri_alloc): Cleared lifetime.
	(df_ignore_stack_reg, df_kill_notes, df_set_notes_for_mw,
	df_create_unused_note): New function.
	(df_ri_bb_compute, df_ri_compute): Added code to create/update
	REG_DEAD and REG_UNUSED notes.
	* reg-stack.c (regstack_completed): New variable.
	(reg_to_stack): Modified to use it's own instance of df.
	(rest_of_handle_stack_regs): Removed most cleanup code.
	* Makefile.in (reorg.o, RESOURCE_H): Added dependancy to df.h.
	(final.o): Removed dependency to df.h
	* passes.c (pass_magic_life): Removed.
	(pass_clear_df): Added.
	* dce.c (prescan_insns_for_dce, end_fast_dce): Now works if no instance of
	df is available.
	(dce_process_block): Made subreg aware.
	(rest_of_handle_fast_dce): Reset bitvectors when iterating.
	(prescan_insns_for_dse): Removed useless code.
