Running "maintainer-release-check" on OS X with Clang 2.9 fails,
because "clang-mp-2.9 -o test -g test.c" launches "/usr/bin/dsymutil
test -o test.dSYM" which fails with "error: unable to open executable
'-o'".
* m4/c-working.m4 (BISON_CHECK_WITH_POSIXLY_CORRECT)
(BISON_C_COMPILER_POSIXLY_CORRECT): New.
* configure.ac: Use the latter.
* tests/atlocal.in (POSIXLY_CORRECT_IS_EXPORTED): New.
* tests/local.at (AT_BISON_CHECK_WARNINGS_): Use it instead of computing its
value each time.
(AT_QUELL_VALGRIND): Skip tests that cannot work because of compilers
that do not support POSIXLY_CORRECT.
* data/c.m4 (b4_yy_location_print_define): New.
Now issues "short" locations, e.g., "1.1" instead of "1.1-1.1".
Was initially a function, but then we face "static but unused"
warnings.
Simpler as a macro.
* tests/local.at, data/glr.c, data/yacc.c: Use it instead of duplicating.
* tests/actions.at: Adjust expectations.
* tests/local.at (AT_YYERROR_DEFINE): Don't display the end of the location
if it is not after its beginning.
* tests/actions.at, tests/cxx-type.at: Adjust the expected output.
* tests/local.at (AT_PARSE_PARAMS): New.
(AT_YYERROR_FORMALS, AT_YYERROR_DEFINE): Use it to add the parse-param
to yyerror.
* tests/calc.at, tests/regression.at: Use AT_YYERROR_DEFINE and
AT_YYERROR_DECLARE, now that they handle properly the parse-params.
Be sure to let AT_BISON_OPTION_PUSHDEFS now what parse-params are used.

parse-gram: update the Bison interface
fix comment
When run as /bin/sh, Bash sets the shell variable POSIXLY_CORRECT to
y. The test suite checks for the envvar POSIXLY_CORRECT to turn of
some tests not supported in POSIX mode. Restore these tests.
Reported by the Hydra build farm, from Rob Vermaas.
* tests/local.at (AT_BISON_CHECK_WARNINGS_): Check the envvar
POSIXLY_CORRECT, not the shell variable.
This feature was introduced in 95a2de5695
(which is part of 2.5), but not documented. Give it a proper name, and
make it public.
* data/c++.m4, data/lalr1.cc, data/glr.cc, data/java.m4: Use
api.location.type instead of location_type.
* src/muscle-tab.c (muscle_percent_variable_update): Map the latter to
the former.
* tests/local.at: Adjust.
* tests/calc.at: Use api.location.type.
Leave tests/java.at with location_type, at least for the time being,
to cover both names.
* doc/bison.texi: Document api.location.type.
(User Defined Location Type): New.
* NEWS: Update.
* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
Use a diversion to avoid outputting comments etc.
Removes 17k lines from testsuite (10% of the number of lines).
* tests/local.at (AT_COMPILE, AT_COMPILE_CXX): If OUTPUT ends with ".o",
then append the "natural" extension for the input file (.c or .cc).
If there is no source, pass -c.
* tests/headers.at, tests/input.at, tests/regression.at: Adjust.
* tests/local.at (AT_NAME_PREFIX): Take api.prefix into account.
(AT_API_PREFIX): Rename as...
(AT_API_prefix): this.
Do not take %name-prefix into account.
Fix misuses.
* tests/local.at (AT_LEX_FORMALS, AT_LEX_ARGS, AT_LEX_PRE_FORMALS)
(AT_LEX_PRE_ARGS): Rename as...
(AT_YYLEX_FORMALS, AT_YYLEX_ARGS, AT_YYLEX_PRE_FORMALS)
(AT_YYLEX_PRE_ARGS): these, for consistency.
(AT_API_PREFIX): Take %name-prefix into account.
(AT_YYLEX_PROTOTYPE): New.
Use it.
* tests/actions.at, tests/calc.at, tests/cxx-type.at: Adjust to
use them.
* tests/local.at (AT_YYERROR_PROTOTYPE): New.
Use it.
* tests/cxx-type.at: Extensive revamp to use a more traditional
quotation scheme, and to use the generic yyerror implementation.
Prefer Autotest macros to CPP macros.
* tests/java.at: .
* tests/local.at (AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE)
(AT_YYERROR_DEFINE): Handle locations for C and C++.
* tests/calc.at: Use it for C++ (as C has extra arguments which
are not yet handled by AT_BISON_OPTION_PUSHDEFS).
* tests/actions.at: Adjust.
* tests/local.at (AT_LANG): Use c++ instead of cxx for C++.
Adjust dependencies.
(AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE): Issue nothing
for C++/Java.
(AT_YYERROR_DEFINE): Use m4_case.
(AT_JAVA_COMPILE): Use AT_SKIP_IF.
Using http://github.com/lyda/misspell-check, massage its
output into sed commands to perform the suggested changes.
Initially, I filtered out the THRU->Through changes, because
that failed to retain capitalization in the grammar token.
Instead, do this manually, beforehand:
sed -i s/THRU/THROUGH/ tests/existing.at
git ls-files|misspellings -f -|perl -nl \
-e '/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/ or next;' \
-e '($file,$n,$l,$r)=($1,$2,$3,$4); $q="'\''"; $r=~s/$q/$q\\$q$q/g;'\
-e 'print "sed -i $q${n}s!$l!$r!$q $file"'|bash
Currently the test 248, "parse-gram.y: LALR = IELR", fails
BISON_TEST_XML is set.
* tests/local.at (AT_BISON_CHECK_XML): Belt: Save/restore files.
* tests/regression.at (parse-gram.y: LALR = IELR): Suspenders: Don't
rely on expout.
Each one of these changes suffices.
Some of our macros play with expout and other Autotest special files,
which may break their callers (e.g., currently TESTSUITEFLAGS='248
BISON_TEST_XML=1' fails).
There is already some support for this. Expand it to be ready to use
it elsewhere.
* tests/local.at (AT_RESTORE_SPECIAL_FILES, AT_SAVE_SPECIAL_FILES)
(at_save_special_files, at_restore_special_files): New.
(AT_BISON_CHECK_NO_XML): Use them.
The Hydra buildfarm provides code coverage analysis. For some reason,
in some test cases, code coverage data seem to be incompatible, and
generate error messages at parser run-time. Ignore these messages so
that (i) these tests do pass, (ii) coverage results be provided by
Hydra.
* tests/local.at (AT_PARSER_CHECK): Ignore messages for failed merges
of code coverage/profiling results.
* tests/local.at: Go for colors.
(--compile-c-with-cxx): New option.
We used to pass "CC=$CXX" as command line argument,
but it was not possible to adjust CFLAGS accordingly
in atlocal, since it is loaded before assignments on
the command line are honored (so that the command line
takes precedence).
* tests/atlocal.in: Implement it.
* tests/local.mk: Use it.

Thus, conflict reports are now affected by -Werror and -Wnone
(unless %expect or %expect-rr is specified). Reported by George
Neuner at

* NEWS (2.5): Document.
* doc/bison.texinfo (Bison Options): Document.
* src/complain.c, src/complain.h (set_warning_issued): Export
function.
* src/conflicts.c (conflicts_print): Suppress conflict report
based on -Wno-conflicts-sr and -Wno-conflicts-rr, and treat
conflicts as errors if -Werror.
* src/getargs.c (warnings_flag): Initialize with
warnings_conflicts_sr and warnings_conflicts_rr as well.
(warnings_args, warnings_types): Add entries for
warnings_conflicts_sr and warnings_conflicts_rr.
(usage): Update.
* src/getargs.h (enum warnings): Add entries for
warnings_conflicts_sr and warnings_conflicts_rr.
* tests/conflicts.at (-W versus %expect and %expect-rr): New test
group.
* tests/local.at (AT_BISON_CHECK_NO_XML): Update now that the
conflict report can produce a "warnings being treated as errors"
message. Also, check that stderr is now fully scrubbed by -Wnone
when the exit status is 0.
Adding command-line options after the grammar file name is not
permitted, so disable checks that do that when
maintainer-check-posix is running.
* tests/local.at (AT_BISON_CHECK_NO_XML): Don't run the
problematic checks when POSIXLY_CORRECT=1. Also, for readability,
remove an unnecessary m4_if.

* NEWS (2.5): Document.
* THANKS (George Neuner): Add.
* doc/bison.texinfo (Bison Options): Document.
* src/complain.c, src/complain.h
(warn_at, warn_at_indent, warn): Suppress warning if -Wno-other.
(midrule_value_at): New warning function, similar to yacc_at in
that it's controlled by its own warning category.
* src/getargs.c (warnings_flag): Initialize to warnings_other.
(warnings_args, warnings_types): Add entry for warnings_other.
(usage): Update.
* src/getargs.h (enum warnings): Add entry for warnings_other.
* src/gram.c (grammar_rules_useless_report): If -Wno-other, then
don't print useless rules.
* src/reader.c (symbol_should_be_used): Rather than adjusting the
return value based on whether midrule value warnings are enabled,
accept a new parameter for telling the caller whether true is
being returned for a potential midrule warning.
(grammar_rule_check): Use midrule_value_at for midrule value
warnings, and continue to use warn_at for all other warnings. Let
them check whether the warnings are enabled.
* tests/local.at (AT_BISON_CHECK): Update documentation.
(AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none
disable all warnings exercised in the test suite.
* NEWS (2.5): Document.
* data/yacc.c (yysyntax_error): In a verbose syntax error
message while in a consistent state with a default action (which
must be an error action given that yysyntax_error is being
invoked), continue to drop the expected token list, but don't
drop the unexpected token unless there actually is no lookahead.
Moreover, handle that internally instead of returning 1 to tell
the caller to do it. With that meaning of 1 gone, renumber
return codes more usefully.
(yyparse, yypush_parse): Update yysyntax_error usage. Most
importantly, set yytoken to YYEMPTY when there's no lookahead.
* data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
unexpected token unless there actually is no lookahead.
* data/lalr1.cc (yy::parser::parse): If there's no lookahead,
set yytoken to yyempty_ before invoking yysyntax_error_.
(yy::parser::yysyntax_error_): Again, don't drop the unexpected
token unless there actually is no lookahead.
* data/lalr1.java (YYParser::parse): If there's no lookahead,
set yytoken to yyempty_ before invoking yysyntax_error.
(YYParser::yysyntax_error): Again, don't drop the unexpected
token unless there actually is no lookahead.
* tests/conflicts.at (%error-verbose and consistent
errors): Extend test group to further reveal how the previous
use of the simple "syntax error" message was too general. Test
yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
failure.
* tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
to...
* tests/local.at: ... here.
(_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
(AT_BISON_OPTION_POPDEFS): Pop it.
(AT_FULL_COMPILE): Extend to handle Java.
