Instead of defining complex list of tuples to define various properties of the symbols, we now prefer to define symbols as "structs" in m4: using the symbol key (its number), and the property name, b4_symbol gives it value. Use this to handle destructors and printers. * src/output.c (CODE_PROP): New. (prepare_symbol_definitions): Use it to define the printer and destructor related attributes of the symbols. * data/lalr1.cc (b4_symbol_actions): Rename as... (b4_symbol_action): this. Use b4_symbol instead of 6 arguments. (b4_symbol_printer, b4_symbol_destructor): New. Use them instead of b4_symbol_actions.
-*- outline -*- This directory contains Bison skeletons: the general shapes of the different parser kinds, that are specialized for specific grammars by the bison program. Currently, there are only three supported skeletons: - yacc.c It used to be named bison.simple: it corresponds to C Yacc compatible LALR(1) parsers. - lalr1.cc Produces a C++ parser class. It is still very experimental, and not yet supported. Please, subscribe to bison-patches@gnu.org. - glr.c A Generalized LR C parser based on Bison's LALR(1) tables. These skeletons are the only ones supported by the Bison team. Because the interface between skeletons and the bison program is not finished, *we are not bound to it*. In particular, Bison is not mature enough for us to consider that ``foreign skeletons'' are supported. ----- Copyright (C) 2002 Free Software Foundation, Inc. This file is part of GNU Bison.
