* NEWS: Remove notice of yytname change, since it was never in an
official release.
* data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
diagnostic.
* src/output.c (prepare): Likewise.
* data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
(yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
is not defined. This is an awful hack, but it's enough for now.
All callers changed.
* tests/glr-regression-at (make_value): Args are const pointers now,
to avoid GCC warning.
(Duplicated user destructor for lookahead): New test. Currently
skipped. It fails on my host but I'm not sure it'll always fail.
All uses changed. Invoke user destructor after an error during a
split parse (trivial change from Joel E. Denny).
* tests/glr-regression.at
(User destructor after an error during a split parse): New test case.
Problem reported by Joel E. Denny in:
http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
void, not int.
* tests/glr-regression.at (Badly Collapsed GLR States):
Likewise.
(Improper handling of embedded actions and dollar(-N) in GLR parsers):
yylex should return 0 at EOF rather than aborting.
Problem reported by twlevo@xs4all.nl.
* data/glr.c (struct yyGLRStack): Remove yyerrflag member.
All uses removed.
(yyStackOverflow): Just longjmp, but with value 2 so that caller
can handle the problem.
(YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
(yyparse): New local variable yyresult to record the result.
Use result of setjmp to set it, rather than storing itinto
struct.
(yyDone): Remove label.
(yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
to mimic yacc.c. Do not discard lookahead if it's EOF (possible
if YYABORT is used).
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
yyparse status; put status > 1 into diagnostic.
Check that status==2 works.
* tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
Use exit status 3 for failure to open (which shouldn't happen).
1 on syntax error; just let yyparse do its thing.
* tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
* tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
(Exploding the Stack Size with Alloca):
(Exploding the Stack Size with Malloc):
Expect exit status 2, not 1, since the parser is supposed to blow
its stack. Problem reported by twlevo@xs4all.nl.
(yyuserMerge): Provide a default case if b4_mergers is empty.
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
* tests/glr-regression.at
(Improper handling of embedded actions and dollar(-N) in GLR parsers):
YYSTYPE is char *, not char const *, so that strcpy ($$, ...) works.
fix a small glitch in debugging output.
(yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
after YY_SYMBOL_PRINT where needed.
(struct yyGLRState): Add some comments.
(struct yySemanticOption): Add some comments.
(union yyGLRStackItem): Add comment.
(yymergeOptionSets): Correct this to properly perform the union,
avoiding infinite reported by Michael Rosien.
Update comment.
* tests/glr-regression.at: Add test for GLR merging error reported
by M. Rosien.
tests/glr-regression.at: Add new regression test for the problems
reported by S. Eken with semantic values for embedded rules.
Update copyright notice.
tests/testsuite.at, tests/Makefile.am: Rename glr-regr1.at to
glr-regression.at.
