place of pull parsing where available. * Makefile.am (maintainer-push-check): New. * data/bison.m4 (b4_use_push_for_pull_if): New. * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if appropriately based on their existing values. (yypush_parse): Don't print push-parser-specific diagnostics if push parsing is being used in place of pull parsing. * data/yacc.c: If push parsing should replace pull parsing, redirect to push.c. * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment variable, and insert b4_use_push_for_pull_flag into muscles. * tests/Makefile.am (maintainer-push-check): New.
-*- 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.
