+
+ * 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):
