Continues Akim's work from his 2009-06-10 commits. * src/reader.c (check_and_convert_grammar): Don't add any symbols after the first symbols_do invocation. * src/symtab.c (symbols_sorted): New static global. (user_token_number_redeclaration): Update comments. (symbol_from_uniqstr): If a new symbol is being created, assert that symbols_sorted hasn't been allocated yet. (symbols_free): Free symbols_sorted. (symbols_cmp, symbols_cmp_qsort): New functions. (symbols_do): Sort symbol_table into symbols_sorted on first invocation. * tests/input.at (Numbered tokens): Recombine tests now that the output should be deterministic across multiple numbers.
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, 2008-2009 Free Software Foundation, Inc.
