skeleton doesn't have to have a copy for pull mode and another for push mode. This patch also fixes at least a bug such that yylloc was not initialized (with b4_location_initial_line and b4_location_initial_column) upon calling yypush_parse. However, that initialization now overwrites the first token's location; %initial-action assigning @$ already did the same thing, and both bugs will be fixed in a later patch. * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa. (b4_declare_parser_state_variables): Remove initialization of yytoken, yyss, yyvs, yyls, and yystacksize. (yypstate_new): Remove initialization of some yypstate fields: yystate, yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and yylsp. (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to yyps->NAME so it can be used in yypush_parse. (yyparse or yypush_parse): For yypush_parse, don't print the "Starting parse" diagnostic for invocations after the first. Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for yypush_parse, only do it for the first invocation. Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc initialization to occur in yypush_parse but only on the first invocation.
-*- 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.
