Subject: 	* symtab.h (enum address_class): Remove LOC_REGPARM and 
 LOC_COMPUTED_ARG. 	(struct symbol): Add is_argument. 
 (SYMBOL_IS_ARGUMENT): Define.

	* ada-lang.c (ada_add_block_symbols): Use SYMBOL_IS_ARGUMENT.
	* buildsym.c (finish_block): Likewise.
	* stack.c (print_frame_args, print_block_frame_locals)
	(print_frame_arg_vars): Likewise.
	* symtab.c (lookup_block_symbol): Likewise.
	* tracepoint.c (add_local_symbols): Likewise.
	* mi/mi-cmd-stack.c (list_args_or_locals): Likewise.

	* coffread.c (process_coff_symbol): Set SYMBOL_IS_ARGUMENT.
	* dwarf2read.c (new_symbol): Likewise.
	* mdebugread.c (parse_symbol): Likewise.
	* stabsread.c (define_symbol): Likewise.

	* ada-exp.y (select_possible_type_sym): Don't handle LOC_REGPARM
	and LOC_COMPUTED_ARG.
	* ada-lang.c (resolve_subexp, symtab_for_sym): Likewise.
	* ax-gdb.c (gen_var_ref): Likewise.
	* eval.c (evaluate_subexp_for_address): Likewise.
	* findvar.c (symbol_read_needs_frame, read_var_value): Likewise.
	* m2-exp.y (yylex): Likewise.
	* printcmd.c (address_info): Likewise.
	* symmisc.c (print_symbol, print_partial_symbols): Likewise.
	* tracepoint.c (collect_symbol, scope_info): Likewise.

testsuite/:
	* gdb.base/frame-args.exp: Handle arguments that are optimized
	out.
