reductions, then output the report anyway if requested, then die. * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. * src/reader.c (eoftoken): New. (parse_token_decl): If the token being defined has value `0', it is the eoftoken. (packsymbols): No longer hack `tags' to insert `$' by hand. Be sure to preserve the value of the eoftoken. (reader): Make sure eoftoken is defined. Initialize nsyms to 0: now eoftoken is created just like the others. * src/print.c (print_grammar): Don't special case the eof token. * src/regression.at: Adjust: `$' has value 0, not -1, which was a lie anyway, albeit pleasant. * tests/calc.at: Exercise error messages with eoftoken. Change the grammar so that empty input is invalid. Adjust expectations. When yyungeting, be sure to use a valid yylloc: use last_yylloc.
This directory contains the Bison parser generator. See the file INSTALL for compilation and installation instructions. See the file doc/FAQ for frequently asked questions. It was once true that, when installing Bison on Sequent (or Pyramid?) systems, you had to be in the Berkeley universe. This may no longer be true; we have no way to tell. 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'. 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. 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.
