Except when memory reallocation is required, this change eliminates the need to invoke yysyntax_error twice and thus to repeat the collection of lookaheads. It also prepares for future extensions that will make those repetitions more expensive and that will require additional memory management in yysyntax_error. Finally, it fixes an obscure bug already exercised in the test suite. * data/yacc.c (yysyntax_error): Add arguments for message buffer variables stored in the parser. Instead of size, return status similar to yyparse status but indicating success of message creation. Other than the actual reallocation of the message buffer, import and clean up memory management code from... (yyparse, yypush_parse): ... here. * tests/regression.at (parse.error=verbose overflow): No longer an expected failure.
-*- outline -*- This directory contains data needed by Bison. * Skeletons Bison skeletons: the general shapes of the different parser kinds, that are specialized for specific grammars by the bison program. Currently, the supported skeletons are: - 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. - lalr1.java Produces a Java parser class. - glr.c A Generalized LR C parser based on Bison's LALR(1) tables. - glr.cc A Generalized LR C++ parser. Actually a C++ wrapper around glr.c. 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. * m4sugar This directory contains M4sugar, sort of an extended library for M4, which is used by Bison to instantiate the skeletons. * xslt This directory contains XSLT programs that transform Bison's XML output into various formats. - bison.xsl A library of routines used by the other XSLT programs. - xml2dot.xsl Conversion into GraphViz's dot format. - xml2text.xsl Conversion into text. - xml2xhtml.xsl Conversion into XHTML. ----- Copyright (C) 2002, 2008-2009 Free Software Foundation, Inc.
