2006-01-02  Paul N. Hilfinger  <hilfinger@adacore.com>

	* ada-exp.y: Considerable reorganization to move functionality
	from ada-lex.l to here, where it is logically more appropriate.
	The original reason, however, was to prevent premature name
	lookups for selector names in record aggregates.

	NAME for all of these.
	(VAR): New artificial token to clarify precedence rules.

	constructions such as X and then Y or else Z.

	(chop_selector): Ditto.
	(write_ambiguous_var): New function, factored out of defunct
	write_var_from_name.
	(write_selectors): New function.
	(write_name_assoc): New function.
	(write_exp_op_with_string): New function.

	* ada-lex.l (processId): Change interface to return stoken.
	(tempbuf, resize_tempbuf, tempbuf_size, tempbuf_len): Remove.
	(block_lookup, name_lookup): Remove.  Functionality moved to
	ada-exp.y.
	(state IN_STRING): Remove.
	(rules): Handle string escapes in processString.
	Add 'others' token.
	Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in
	yylval.sval (as simple strings).
	All name look-ups now handled in ada-exp.y.
	Introduce "::" (COLONCOLON) token and return as separate token.
	(processId): Change return convention.  Comment.
	Leave leading "'" in place.
	(processString): New function.
	(find_dot_all): Add note to comment.
	Fix problem that allowed match only at the end.

	(aggregate_assign_from_choices,aggregate_assign_positional)
	(aggregate_assign_others,add_component_interval):
	New functions.
	(ada_evaluate_subexp): Declare.
	Add aggregate-related operators.
	(ada_forward_operator_length): Declare.
	(resolve_subexp): Add cases for new aggregate operators and OP_NAME.
	Consolidate Ada operators, using ada_forward_operator_length.
	(ada_search_struct_field): Search in forward order.
	(ADA_OPERATORS): Add new aggregate operators.
	(ada_operator_length, ada_op_name, ada_forward_operator_length)
	(ada_dump_subexp_body, ada_print_subexp): Handle new aggregate

	subprograms. 
	Also add missing handling for__{DIGITS}+ suffixes.
	Allow '$<digits>' as valid overloading suffix.
	(is_name_suffix): Add handling for protected type entriy suffixes.
	Also add support for protected type subprogram suffixes, but keep
	it commented out for now, as there is an ambiguity between these
	entities and other internally generated entities.
	Allow '$<digits>' as valid overloading suffix.
	(is_valid_name_for_wild_match): New function.
	(wild_match): Add an exra level of verification of the entity name
	before declaring it a match for the given pattern.

	buffer for extracting packed record fields that are themselves records.

	(add_defn_to_vec): Do not try to replace a stub type by its full
	type. Avoids a potential infinite loop.
	
	(ada_lookup_symbol): Move return incorrectly placed return statement, 
	causing a loop that should be scanning all object files to only 
	scan the first one.

	(ada_tag_name_2): New function.

	use alternative representation.

	(ada_check_typedef): Replace expression checking whether the given

	'$' in addition to '.' for runtime auxiliary function name suffixes.
	See changes to ada_decode above.

	(struct task_control_block): Add field called_task.  (This change is
	to keep synchronized with our local sources; it does not affect the
	public version yet.)

	* ada-typeprint.c (ada_print_type): Use int_string for printing
	modulus of modular type.
	
	(print_range): Trivial editorial comment fix.
