state before an empty RHS is always resolved here. Only the location of that state is guaranteed to be resolved, and that's enough. This fixes the remaining bug reported by Derek M. Jones in <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>. * tests/glr-regression.at (Uninitialized location when reporting ambiguity): Test the above case. Also, the embedded comments in this test case claim it checks the case of an empty RHS that has inherited the initial location. However, the corresponding LHS was already resolved, so yyresolveLocations didn't actually have reason to modify it. Fix this by forcing nondeterministic operation at the beginning of the parse.
-*- 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.
