deserves most of the credit). * Makefile.am (SUBDIRS): Add etc subdirectory. * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile. * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult, yytoken, yyval, and yyloc declarations to... (yyparse or yypush_parse): ... here to improve performance. For yypush_parse invocations after the first, be sure to assign yyn its old value again. (yypstate_new): Don't bother initializing the yyresult field since the initial value isn't used. (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list, remove the #define that, in push mode, set it to yyps->NAME. * etc/Makefile.am: New. * etc/bench.pl: Remove and build it instead from... * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke "tests/bison" from the build directory by default rather than just invoking "bison" from $PATH. (calc_grammar): Update push parser code: don't declare yylval globally, don't define yyparse_wrapper, and don't #define yyparse. (bench_grammar): Update to check all working combinations of yacc.c, push.c, impure, pure, pull, and push.
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.
