GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no lookahead symbol, and which sets yychar in parser actions) and it disagreed with the Bison documentation. This should fix the bug reported by Andrew Walrond in <http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>. (YYTRANSLATE): Don't check for negative argument, as the caller now does that. (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken. (YYEMPTY): Parenthesize right hand side, since others use it. (yyparse): Don't assume that our generated code is the only code that sets yychar.
-*- 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.
