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.
	(BLOCKNAME, TYPENAME, OBJECT_RENAMING): Remove; lexer now returns
	NAME for all of these.
	(VAR): New artificial token to clarify precedence rules.
	(OTHERS): New lexeme.
	(empty_stoken): New symbol.
	(%union): Remove ssym, voidval.
	(%type): Remove <voidval> type declarations.
	(syntax definitions): Add aggregates.
	Remove distinction between NAME, TYPENAME, BLOCKNAME, OBJECT_RENAMING.
	Rename some non-terminals to be closer to reference manual usage.
	Tighten up expression syntax to disallow certain non-Ada 
	constructions such as X and then Y or else Z.
	(ada_parse): Remove initialization of left_block_context.
	(write_var_from_name): Remove.
	(write_var_or_type): New function, containing previous code from
	defunct write_var_from_name and name_lookup.
	(block_lookup): New function, moved from ada-lex.l
	(select_possible_type_sym): New function, factored out of
	name_lookup, which used to be in ada-lex.l.
	(find_primitive_type): Ditto.
	(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.

	* ada-lang.c: Introduce aggregates.
	(find_struct_field): Add new parameter to count fields skipped, and
	allow other output parameters to be NULL.
	(value_tag_from_contents_and_address, ada_value_struct_elt): Use 
	new find_struct_field.
	(ada_index_struct_field, assign_aggregate, ada_is_array_type)
	(num_visible_fields, ada_index_struct_field_1, ada_index_struct_field)
	(num_component_specs, assign_component, assign_aggregate):
	(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 
	operators and OP_NAME.
	(ada_type_of_array): Use longest_to_int.
	(value_assign_to_component): New function.
	(ada_forward_operator_length, ada_op_name, ada_dump_subexp_body):
	Add OP_NAME case.
	(ada_forward_operator_length, ada_dump_subexp_body):
	Add OP_STRING case.

	* ada-lang.h (enum ada_operator): Add OP_AGGREGATE, OP_OTHERS,
	OP_CHOICES, OP_DISCRETE_RANGE, OP_POSITIONAL.

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

	* ada-lang.c (process_raise_exception_name): Remove extraneous 
        definition from unsubmitted code.

	(is_lower_alphanum): New function.
	(ada_decode):  Add support for decoding protected object subprograms
	and entries, and of entities declared inside protected object
	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.

	(ada_type_of_array, ada_evaluate_subexp): Use more proper 
	longest_to_int rather than cast.

	(ada_evaluate_subexp): Use "invalid" rather than "illegal" in comment.

	(ada_coerce_to_simple_array): Call check_size to make sure
	that the object size is reasonable.

	(ada_value_primitive_packed_val):  Use correct location in target 
	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.
	(ada_tag_name_1): If no 'tsd' field found in the dispatching table,
	use alternative representation.

	(ada_find_renaming_symbol): Strip the function name suffix when 
	computing the XR type name.

	(ada_to_fixed_type): Try determining the tag only if we have the
	object's address.
	(to_fixed_array_type): Add comments.

	(ada_check_typedef): Replace expression checking whether the given
	type is a stub or not by a "call" to TYPE_STUB. Clearer and more
	consistent.
	
	* ada-lang.h (ADA_KNOWN_AUXILIARY_FUNCTION_NAME_PATTERNS): Allow
	'$' 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.

	* ada-valprint.c (ada_emit_char): Use normal Ada syntax for 
	double quote in string.
