Instead of defining complex list of tuples to define various properties of the symbols, we now prefer to define symbols as "structs" in m4: using the symbol key (its number), and the property name, b4_symbol gives it value. Use this to handle destructors and printers. * src/output.c (CODE_PROP): New. (prepare_symbol_definitions): Use it to define the printer and destructor related attributes of the symbols. * data/lalr1.cc (b4_symbol_actions): Rename as... (b4_symbol_action): this. Use b4_symbol instead of 6 arguments. (b4_symbol_printer, b4_symbol_destructor): New. Use them instead of b4_symbol_actions.
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.
