non-aliased/undeclared string literals since it might be useful to those declaring %token-table. * src/reader.c (check_and_convert_grammar): Undo changes in previous commit: don't worry about complaints from symbols_pack. * src/symtab.c (symbol_new, symbol_class_set, symbol_check_alias_consistency): Undo changes in previous commit: count each string literal as a new symbol and token, assign it a symbol number, and don't complain about non-aliased string literals. (symbols_pack): Since symbol_make_alias still does not decrement symbol and token counts but does still set aliased tokens to the same number, symbol_pack_processor now leaves empty slots in the symbols array. Remove those slots. * tests/regression.at (Undeclared string literal): Remove test case added in previous commit since non-aliased string literals are allowed again. (Characters Escapes, Web2c Actions): Undo changes in previous commit: remove unnecessary string literal declarations. * tests/sets.at (Firsts): Likewise.
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.
