* data/lalr1.cc (b4_cxx_destruct_def): New macro. (Parser::stos_): Define unconditionally. (Parser::destruct_): New method. Generate its body with b4_yydestruct_generate. (Parser::error_start_): New attribute. (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous token which are discarded. (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update error_start_ when erroneous token are discarded. (Parser::parse) <yyerrlab1>: Compute the location of the error token so that it covers all the discarded tokens. * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so it can be called with `%skeleton "lalr1.cc"', and do that.
-*- 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.
