   2
   3         * ada-exp.y: Considerable reorganization to move functionality
   4         from ada-lex.l to here, where it is logically more appropriate.
   5         The original reason, however, was to prevent premature name
   6         lookups for selector names in record aggregates.
   7         (BLOCKNAME, TYPENAME, OBJECT_RENAMING): Remove; lexer now returns
   8         NAME for all of these.
   9         (VAR): New artificial token to clarify precedence rules.
  10         (OTHERS): New lexeme.
  11         (empty_stoken): New symbol.
  12         (%union): Remove ssym, voidval.
  13         (%type): Remove <voidval> type declarations.
  14         (syntax definitions): Add aggregates.
  15         Remove distinction between NAME, TYPENAME, BLOCKNAME, OBJECT_RENAMING.
  16         Rename some non-terminals to be closer to reference manual usage.
  17         Tighten up expression syntax to disallow certain non-Ada
  18         constructions such as X and then Y or else Z.
  19         (ada_parse): Remove initialization of left_block_context.
  20         (write_var_from_name): Remove.
  21         (write_var_or_type): New function, containing previous code from
  22         defunct write_var_from_name and name_lookup.
  23         (block_lookup): New function, moved from ada-lex.l
  24         (select_possible_type_sym): New function, factored out of
  25         name_lookup, which used to be in ada-lex.l.
  26         (find_primitive_type): Ditto.
  27         (chop_selector): Ditto.
  28         (write_ambiguous_var): New function, factored out of defunct
  29         write_var_from_name.
  30         (write_selectors): New function.

  35         (tempbuf, resize_tempbuf, tempbuf_size, tempbuf_len): Remove.
  36         (block_lookup, name_lookup): Remove.  Functionality moved to
  37         ada-exp.y.
  38         (state IN_STRING): Remove.
  39         (rules): Handle string escapes in processString.
  40         Add 'others' token.
  41         Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in
  42         yylval.sval (as simple strings).
  43         All name look-ups now handled in ada-exp.y.
  44         Introduce "::" (COLONCOLON) token and return as separate token.
  45         (processId): Change return convention.  Comment.
  46         Leave leading "'" in place.
  47         (processString): New function.
