"initial push" (corresponding to an hypothetical beginning-of-file). And let lalr1.cc honor %initial-action. * doc/bison.texinfo (Initial Action Decl): Clarify, and add an example. * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment. (Parser::Parser): Remove the ctor that used to initialize it. (Parser::parse): Like in the other skeletons, issue the "starting parse" message before any action. Honor %initial-action. Initialize the stacks with the lookahead. * data/yacc.c: Let $$ and @$ in %initial-action designate the look-ahead. Push them in the stacks. * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
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 or later. Vanilla GNU m4 1.4 has some serious bugs, so we recommend using m4 1.4 as patched by the standard GNU/Linux distributions. If you're building GNU m4 1.4 from scratch we suggest using this version: ftp://alpha.gnu.org/gnu/bison/m4-1.4.1.tar.gz Older versions of Sun Forte Developer 6 update 2 have a compiler bug that cause "make check" to fail with a "Encounter BINCL entry" diagnostic. To fix the bug, update to the latest set of Solaris and Forte patches recommended by Sun. VMS and MS-DOS builds are probably broken right now. If you are able to build Bison on either platform and you need to make changes to do so, please submit those changes as a bug report. On VMS, you will probably have to create Makefile from Makefile.in by hand. Remember to do `SET COMMAND BISON' to install the data in `BISON.CLD'. 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 which the documentation does not answer, send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004 Free Software Foundation, Inc.
