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

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