* data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE comments: zero indicates syntax error not default action. * data/c.m4 (b4_table_value_equals): Comment that YYID must be defined. * data/glr.c (yyis_pact_ninf): Rename to... (yypact_value_is_default): ... this. (yyisDefaultedState): Update for rename. (yyis_table_ninf): Rename to... (yytable_value_is_error): ... this, and check for value zero besides just YYTABLE_NINF. (yygetLRActions): Check for default value from yypact. It appears that this check is always performed before this function is invoked, and so adding the check here is probably redundant. However, the code may evolve after this subtlety is forgotten. Also, update for rename to yytable_value_is_error. Because that macro now checks for zero, a different but equivalent branch of the if-then-else here is evaluated. (yyreportSyntaxError): Update for rename to yytable_value_is_error. The zero condition was mishandled before. (yyrecoverSyntaxError): Update for renames. No behavioral changes. * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_): New function. (yy_table_value_is_error_): New function. (parse): Use new functions where possible. No behavioral changes. (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_. The zero condition was mishandled before. * data/yacc.c (yyis_pact_ninf): Rename to... (yypact_value_is_default): ... this. (yyis_table_ninf): Rename to... (yytable_value_is_error): ... this, and check for value zero besides just YYTABLE_NINF. (yysyntax_error): Update for rename to yytable_value_is_error. The zero condition was mishandled before. (yyparse): Update for renames. No behavioral changes. * src/tables.h: Improve comments about yypact, yytable, etc. more. Most importantly, say yytable value of zero means syntax error not default action.
This package contains the GNU Bison parser generator.
* Installation
** Build
See the file INSTALL for generic compilation and installation
instructions.
Bison requires GNU m4 1.4.6 or later. See:
ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
** Internationalization
Bison supports two catalogues: one for Bison itself (i.e., for the
maintainer-side parser generation), and one for the generated parsers
(i.e., for the user-side parser execution). The requirements between
both differ: bison needs ngettext, the generated parsers do not. To
simplify the build system, neither are installed if ngettext is not
supported, even if generated parsers could have been localized. See
http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
more details.
* Questions
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".
If you have questions about using Bison and the documentation does
not answer them, please send mail to <help-bison@gnu.org>.
* Bug reports
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.
