* NEWS: Document the behavior changes. * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the stack before failing, as the cleanup code will do it for us now. * data/lalr1.cc (yyerrlab): Likewise. * data/glr.c (yyparse): Pop everything off the stack before freeing it, so that destructors get called properly. * data/lalr1.cc (yyreturn): Likewise. * data/yacc.c (yyreturn): Pop and destroy the start symbol, too. This is more consistent. * doc/bison.texinfo (Destructor Decl): Mention more reasons why destructors might be called. 1.875 -> 2.1. (Destructor Decl, Decl Summary, Table of Symbols): Some English-language cleanups for %destructor. * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Add output line for destructor of start symbol. * tests/calc.at (AT_CHECK_CALC): Add one to line counts, because of that same extra output line.
This directory contains the Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the file doc/FAQ for frequently asked questions. Bison requires GNU m4 1.4.3 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz Bison can work with pre-1.4.3 distributions of GNU m4 if they are sufficiently patched, but if you encounter a bug with an older distribution and report a bug we will probably suggest that you upgrade to 1.4.3 as the first step in trying to fix it. Please send bug reports to <bug-bison@gnu.org>. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005 Free Software Foundation, Inc.
