* NEWS (2.5): Add an entry. * src/getargs.c (usage): Mention IELR(1) and canonical LR(1) besides just LALR(1) and GLR(1). * doc/bison.texinfo (Introduction): Likewise. (Language and Grammar): Bison is no longer limited to LALR(1) restrictions. (GLR parsing): Say deterministic or LR(1) rather than LALR(1) when trying to distinguish from GLR. Talk about LR(1) grammars rather than LALR(1) grammars. (Decl Summary): In %define api.push_pull entry, say it applies to deterministic parsers in C rather than LALR(1) parsers in C. Add lr.default_rules entry. Add lr.type entry. (Mystery Conflicts): Bison is no longer limited to LALR(1) restrictions. (Generalized LR Parsing): Same changes as for the previous GLR section. (Memory Management): Say deterministic rather than LALR(1). (Understanding): Correct some bison output. Index discussion of "accepting state". Say deterministic rather than LALR(1). (Bison Options): In --yacc entry, say deterministic rather than LALR(1). In --report, --graph, and --xml entries, just don't mention LALR(1). (C++ Parsers): Say deterministic rather than LALR(1). (Table of Symbols): Likewise in YYSTACK_USE_ALLOCA entry. (Glossary): Add Accepting State, Consistent State, Default Rule, and IELR(1) definitions. In Generalized LR (GLR) definition, make same changes as in previous GLR sections. In LALR(1) definition, say Bison uses LALR(1) by default rather than implying Bison is limited to LALR(1). (LocalWords): Add IELR.
This package contains the GNU Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the section FAQ in the documentation (doc/bison.info) for frequently asked questions. The documentation is also available in PDF and HTML, provided you have a recent version of Texinfo installed: run "make pdf" or "make html". Bison requires GNU m4 1.4.6 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz Bison can work with pre-1.4.6 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 1.4.6 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, 2008 Free Software Foundation, Inc.
