* data/glr.cc (b4_parse_param_orig): New. (b4_parse_param): Improve its definition, and bound it more clearly in the skeleton. (b4_epilogue): Append, instead of prepending, in order to keep #line consistency. Simplify the generation of auxiliary functions: locations and purity are mandated. (b4_global_tokens_and_yystype): Honor it. * data/location.cc (c++.m4): Don't include it. * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF and AT_SKEL_CC_IF. * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of AT_LALR1_CC_IF. Be sure to initialize the first position's filename. (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are mandated anyway. (AT_CHECK_CALC_GLR_CC): New. Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
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.
