Problem reported by twlevo@xs4all.nl. * data/glr.c (struct yyGLRStack): Remove yyerrflag member. All uses removed. (yyStackOverflow): Just longjmp, but with value 2 so that caller can handle the problem. (YYCHK1): Use goto (a la yacc.c) rather than setting a flag. (yyparse): New local variable yyresult to record the result. Use result of setjmp to set it, rather than storing itinto struct. (yyDone): Remove label. (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels, to mimic yacc.c. Do not discard lookahead if it's EOF (possible if YYABORT is used). * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with yyparse status; put status > 1 into diagnostic. Check that status==2 works. * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at: Use exit status 3 for failure to open (which shouldn't happen).
-*- 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.
