(yylval, yylloc): If pure, #define to yystackp->yyval and yystackp->yyloc similar to yychar and yynerrs. (yyparse): If pure, remove local yylval and yylloc. Add local yystackp to accommodate pure definitions of yylval and yylloc. (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change yylvalp and yyllocp to &yylval and &yylloc. (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[] namespace. Previously, nerrs and char were missing, but lval and lloc weren't necessary. (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove yylvalp and yyllocp parameters since, if pure, these are now always accessible through yystackp. If not pure, they are still accessible globally. * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to `if (YYID (N))' to pacify lint.
-*- 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.
