* data/yacc.c: Rename %define variable parse.lac.es-capacity to parse.lac.es-capacity-initial. Accept parse.lac.memory-trace with values of "failures" (default) or "full". (b4_declare_parser_state_variables): Add yyesa, yyes, and yyes_capacity variables. (YYSTACK_USE_ALLOCA): Ignore it if LAC requested. (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if LAC requested. (YYCOPY_NEEDED): New cpp macro. (YYCOPY): Define if LAC requested. (yy_lac_stack_realloc): New function implementing stack reallocations. Use YYMAXDEPTH for maximum stack size given that the stack should never need to grow larger than the main state stack needs to grow without LAC. (YY_LAC_ESTABLISH): Update yy_lac invocation. (yy_lac): Add arguments for exploratory stack memory data recorded in the main parser. Invoke yy_lac_stack_realloc when reallocation is necessary. (yysyntax_error): Add the same new arguments and pass them to yy_lac. (yypstate_delete): Free yyes if necessary. (yyesa, yyes, yyes_capacity): #define these to yypstate members in the case of push parsing. (yyparse, yypush_parse): Initialize yyes and yyes_capacity. Update yysyntax_error invocations. At yyreturn, free yyes if necessary. * src/parse-gram.y: %define parse.lac full. * tests/input.at (LAC: errors for %define): Extend for parse.lac-memory-trace. * tests/regression.at (LAC: Exploratory stack): Extend to check that stack reallocs happen when expected. (LAC: Memory exhaustion): Update to use YYMAXDEPTH and parse.lac.es-capacity-initial.
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.
