	* rtl.def (VAR_LOCATION): New.
	* rtl.h (NOTE_VAR_LOCATION): New.
	(NOTE_VAR_LOCATION_DECL): New.
	(NOTE_VAR_LOCATION_LOC): New.
	(enum insn_note): NOTE_INSN_VAR_LOCATION was added.
	(note_all_uses): New exported function.
	(variable_tracking_main): New exported function.
	* rtlanal.c (note_all_uses): New function.
	* timevar.def (TV_VAR_TRACKING): New.
	* toplev.c (enum dump_file_index): Added DFI_vartrack.
	(dump_file): "vartrack" was added (-dV).
	(flag_var_tracking): New.
	(f_options): "var-tracking" was added.
	(rest_of_compilation): Run variable tracking.
	(process_options): If user has not specified flag_var_tracking set it
	according to optimize, debug_info_level and debug_hooks.

	Daniel Berlin <dberlin@dberlin.org>
	* debug.h (struct gcc_debug_hooks): Added var_location debug hook.
	* dbxout.c (dbx_debug_hooks): Likewise.
	(xcoff_debug): Likewise.
	* debug.c (do_nothing_debug_hooks): Likewise.
	* dwarf2out.c (dwarf2_debug_hooks): Likewise.
	* dwarfout.c (dwarf_debug_hooks): Likewise.
	* sdbout.c (sdb_debug_hooks): Likewise.
	* vmsdbgout.c (vmsdbg_debug_hooks): Likewise.
	* final.c (final_scan_insn): Call var_location debug hook for each
	NOTE_INSN_VAR_LOCATION.
	* dwarf2out.c (struct gcc_debug_hooks): Call dwarf2out_begin_function
	at the beginning of function, call dwarf2out_var_location for
	NOTE_INSN_VAR_LOCATION note.
	(struct var_loc_node, struct var_loc_list_def, loclabel_num,

	output addr instead of delta, Location list terminators should be
	DWARF2_ADDR_SIZE long.
	(output_die): Use dw2_asm_output_offset, not dw2_asm_output_delta, for
	location list labels.
	(based_loc_descr): Added parameter can_use_fbreg, DW_OP_fbreg is used

	with attr == DW_AT_location.
	(gen_subprogram_die): Generate the location list for DW_AT_frame_base
	if frame_base_decl is defined and has a location list.
	(gen_variable_die): Call add_location_or_const_value_attribute with
	attr == DW_AT_location.
	(dwarf2out_var_location): New function.
	(dwarf2out_begin_function): New function.
	(dwarf2out_init): Create decl_loc_table and initialize
	decl_loc_table_allocated and decl_loc_table_in_use.
