alloca function (when available) to extend the parser stack, due to widespread problems in unchecked stack-overflow detection. * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's responsibility to set it to a positive value. This lets the user specify a value that is not a preprocessor constant. * data/yacc.c (YYMAXDEPTH): Likewise. (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero. * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs to be a compile-time constant. However, explain the constraints on it. Also, explain the constraints on YYINITDEPTH. (Table of Symbols): Explain that alloca is no longer the default. Explain the user's responsibility if they define YYSTACK_USE_ALLOCA to 1.
-*- outline -*- This directory contains Bison skeletons: the general shapes of the different parser kinds, that are specialized for specific grammars by the bison program. Currently, there are only three supported skeletons: - yacc.c It used to be named bison.simple: it corresponds to C Yacc compatible LALR(1) parsers. - lalr1.cc Produces a C++ parser class. It is still very experimental, and not yet supported. Please, subscribe to bison-patches@gnu.org. - glr.c A Generalized LR C parser based on Bison's LALR(1) tables. These skeletons are the only ones supported by the Bison team. Because the interface between skeletons and the bison program is not finished, *we are not bound to it*. In particular, Bison is not mature enough for us to consider that ``foreign skeletons'' are supported. ----- Copyright (C) 2002 Free Software Foundation, Inc. This file is part of GNU Bison.
