Bison directive from the Bison file to the invocation of this macro, so that these directives are passed to AT_BISON_OPTION_PUSHDEFS to get correct help macros. Use these helping macros (e.g., AT_LOC, AT_VAL and so forth). Move the AT_SETUP/AT_CLEANUP outside, to report as test title the extra Bison directives instead of the whole series. Change the grammar so that there are recoverable errors, and unrecoverable errors. Now we can have the parser give up before consuming the whole input. As a result we now can observe that the lookahead is freed when needed. Change the parser source to parse argv[1] instead of a hard coded string. Simplify yylex, and give a value and location to EOF. Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that passed directives already coded in the file. Add some tests to check the location of "error". For some tests, the C++ parser is correct, and not yacc.c. For other tests, they provide different, but unsatisfying, values, so keep the C++ value so that at least one parser is "correct" according to the test suite. (Actions after errors): Remove, this is subsumed by the AT_CHECK_PRINTER_AND_DESTRUCTOR series.
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 or later. Vanilla GNU m4 1.4 has some serious bugs, so we recommend using m4 1.4 as patched by the standard GNU/Linux distributions. If you're building GNU m4 1.4 from scratch we suggest using this version: ftp://alpha.gnu.org/gnu/bison/m4-1.4.1.tar.gz Older versions of Sun Forte Developer 6 update 2 have a compiler bug that cause "make check" to fail with a "Encounter BINCL entry" diagnostic. To fix the bug, update to the latest set of Solaris and Forte patches recommended by Sun. VMS and MS-DOS builds are probably broken right now. If you are able to build Bison on either platform and you need to make changes to do so, please submit those changes as a bug report. On VMS, you will probably have to create Makefile from Makefile.in by hand. Remember to do `SET COMMAND BISON' to install the data in `BISON.CLD'. 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 which the documentation does not answer, send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004 Free Software Foundation, Inc.
