	gcc            : ChangeLog defaults.h dwarf2out.c function.c 
	                 tree.h var-tracking.c 

Log message:
	* function.c (ARG_POINTER_CFA_OFFSET): Move ...
	* defaults.h (ARG_POINTER_CFA_OFFSET): ... here.
	(INCOMING_FRAME_SP_OFFSET): Move from dwarf2out.c.
	* dwarf2out.c (struct cfa_loc): Change reg to unsigned int,
	rearrange for better packing.
	(INCOMING_FRAME_SP_OFFSET): Move to defaults.h.
	(lookup_cfa_1): Remove inline marker.
	(cfa_equal_p): Split out of ...
	(def_cfa_1): ... here.  Use INVALID_REGNUM.
	(build_cfa_loc): Handle !cfa->indirect.
	(frame_pointer_cfa_offset): New.
	(dbx_reg_number): Assert register elimination performed; do
	leaf register remapping.
	(reg_loc_descriptor): Avoid calling dbx_reg_number when unused.
	(eliminate_reg_to_offset): New.
	(based_loc_descr): Remove can_use_fbreg argument.  Use fbreg only
	for verifiably local stack frame addresses; re-base to CFA.
	(mem_loc_descriptor): Remove can_use_fbreg argument.
	(concat_loc_descriptor, loc_descriptor): Likewise.
	(containing_function_has_frame_base): Remove.
	(rtl_for_decl_location): Don't do register elimination or
	leaf register remapping here.
	(secname_for_decl): Split out from ..
	(add_location_or_const_value_attribute): ... here.
	(convert_cfa_to_loc_list): New.
	(compute_frame_pointer_to_cfa_displacement): New.
	(gen_subprogram_die): Use them.
	* tree.h (frame_base_decl): Remove.
	* var-tracking.c (frame_base_decl, frame_stack_adjust): Remove.
	(prologue_stack_adjust): Remove.
	(vt_stack_adjustments): Use INCOMING_FRAME_SP_OFFSET.
	(adjust_stack_reference): Re-base memories to arg_pointer_rtx.
	(set_frame_base_location): Remove.
	(compute_bb_dataflow, emit_notes_in_bb): Don't call it.
	(dump_attrs_list, dump_dataflow_set): Use string concatenation.
	(vt_add_function_parameters): Don't eliminate_regs.
	(vt_initialize): Don't create frame_base_decl.
