(.x.1): Don't use neutralize.
(edit): Don't substitute for ID.
(Doxyfile): Don't define Id, and thus don't depend on ChangeLog.
* doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
$(top_srcdir)/configure.ac so that changes to computed variables, such
as PACKAGE_VERSION, are seen.
* tests/Makefile.am ($(srcdir)/package.m4): Likewise.
starting at
<http://lists.gnu.org/archive/html/bison-patches/2007-11/msg00021.html>.
* configure.ac (XSLTPROC): New substitution.
* Makefile.am (maintainer-xml-check): New phony target invoking...
* tests/Makefile.am (maintainer-xml-check): ... this new phony target
invoking make maintainer-check with BISON_TEST_XML=1.
* tests/atlocal.in (XSLTPROC): New.
* tests/local.at (AT_BISON_CHECK): New macro to (1) instruct Valgrind
not to report reachable memory when Bison is expected to have a
non-zero exit status and (2) to compare XML/XSLT output with --graph
and --report=all output for every working grammar when
BISON_TEST_XML=1.
(AT_BISON_CHECK_NO_XML): Likewise, but skip XML checks.
(AT_BISON_CHECK_XML): New.
(AT_QUELL_VALGRIND): New.
* tests/testsuite.at (ORIGINAL_AT_CHECK): Remove this and...

(Big triangle): Use AT_BISON_CHECK_NO_XML instead since this grammar
tends to hang xsltproc.
(Big horizontal): Likewise.

Discussed starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
* doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
(Bison Options): Document in --skeleton entry.
* src/output.c (output_skeleton): Use strncpy rather than strcpy since
full_skeleton can't necessarily hold all of pkgdatadir.
If the specified skeleton file name contains a `/', don't prepend
pkgdatadir.
* src/parse-gram.y (prologue_declaration): If the specified skeleton
file name contains a `/', prepend the grammar file directory.
* tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
* skeletons.at: New file.
(relative skeleton file names): New test case.
(installed skeleton file names): New test case.
* tests/testsuite.at: Include skeletons.at.
* bootstrap: Update copyright to 2007.
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.
* src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
(spec_defines_file, dir_prefix): Now char *, not const char *,
since they are freed.
* src/files.c: Likewise.
(all_but_ext, all_but_tab_ext, src_extension, header_extension):
Likewise.
(tr): Now operates in-place. All uses changed.
(compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
values.
(compute_file_name_parts, compute_output_file_names): Don't store
read-only data in variables that will be freed.
(compute_output_file_names): Free all_but_ext, all_but_tab_ext,
src_extension, and header_extension.
(output_file_names_free): New public function to free
spec_verbose_file, spec_graph_file, spec_defines_file,
parser_file_name, and dir_prefix.
* src/getargs.c (getargs): Don't store read-only data in variables that
will be freed.
* src/main.c (main): Invoke output_file_names_free, code_scanner_free
(which previously existed but was unused), and quotearg_free.
* src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
* src/muscle_tab.c: Likewise.
(muscle_entry): Make the value char const *,
and add a new storage member that is char * and can be freed.
(muscle_entry_free): New private function.
(muscle_init): Use it instead of free.
(muscle_insert, muscle_grow): Update and use new storage member.
(muscle_code_grow): Free the string passed to muscle_grow
since it's not needed anymore.
* src/parse-gram.y (%union): Make `chars' member a `char const *', and
add a new `char *code' member.
("{...}"): Declare semantic type as code.
* src/scan-code.h (translate_rule_action):
(translate_symbol_action, translate_code, translate_action): Return
`char const *' rather than `char *' since external code should not free
these strings.
* src/scan-code.l: Likewise.
* src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
which is "{...}" in the parser.
* tests/Makefile.am (maintainer-check-valgrind): Set
VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
Valgrind.
* tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
complain.
* tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
expecting a non-zero exit status sets --leak-check=summary and
--show-reachable=no for Valgrind. Bison unabashedly leaks memory in
this case, and we don't want to hear about it.
* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
the user's name space. All uses changed to __attribute__
((__unused__)).
(yyFail, yyMemoryExhausted, yyreportAmbiguity):
Add __attribute__ ((__noreturn__)).
* etc/clcommit: Remove. We weren't using it, and it failed
"make maintainer-distcheck".
* Makefile.maint: Merge from coreutils.
(CVS_LIST, CVS_LIST_EXCEPT): New macros.
(syntax-check-rules): Change list of rules as described below.
(sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
(sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
(sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
(sc_trailing_space): New rules.
(sc_xalloc_h_in_src): Remove.
(sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
(sc_space_tab, sc_error_exit_success, sc_changelog):
(sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
(makefile-check, po-check, author_mark_check):
(makefile_path_separator_check, copyright-check):
Use grep -n, to make it easier to find violations.
Use CVS_LIST and CVS_LIST_EXCEPT.
(header_regexp, h_re): Remove.
(dd_c): New macro.
(sc_dd_max_sym_length, .re-list, news-date-check): New rules.
(my-distcheck): Use more-modern GCC flags.
(signatures, %.asc): Remove.
(rel-files, announcement): Remove signatures.
Restore old updating code, even though we don't use it, so
that we're the same as coreutils.
(alpha, beta, major): Depend on news-date-check.
Make the upload commands.
* data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
* lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
* lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
* lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
* src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
* src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
* src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
* tests/sets.at: Likewise.
* data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
we comment out the Autoconf version number.
* doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
it's error-prone and "make maintainer-distcheck" rejects it.
* lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
Indent calls to "error" to pacify "make maintainer-distcheck",
when the calls are not intended to be translated.
* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
* src/Makefile.am (DEFS): Use +=, to pacify
"make maintainer-distcheck".
(bison_SOURCES): Add scan-skel.h.
(sc_tight_scope): New rule, from coreutils.
* src/files.c (src_extension, header_extension):
Now static, not extern.
* src/getargs.c (short_options): Likewise.
* src/muscle_tab.c (muscle_table): Likewise.
* src/parse-gram.y (current_class, current_type, current_prec):
Likewise.
* src/reader.c (grammar_end, previous_rule_end): Likewise.
* src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
* src/main.c (main): Cast bindtextdomain and textdomain calls to
void, to avoid warning when NLS is disabled.
* src/output.c: Include scan-skel.h.
(scan_skel): Remove decl, since scan-skel.h does this.
(output_skeleton):
Indent calls to "error" to pacify "make maintainer-distcheck".
* src/print_graph.c: Don't include <obstack.h>, as system.h does this.
* src/reader.h (gram_end, gram_lineno): New decls to pacify
"make maintainer-distcheck".
* src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
(skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
(skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
(skel_lex_destroy, scan_skel): Move these decls to...
* src/scan-skel.h: New file.
* src/uniqstr.c (uniqstr_assert):
Indent calls to "error" to pacify "make maintainer-distcheck".
* tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
not @VAR@.
* tests/torture.at: Revamp to avoid misuse of atoi that
"make maintainer-distcheck" complained about.
test for valgrind; valgrind is independent of g++.
(maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
for compatibility with POSIX 1003.1-2001 (if running coreutils).
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
Use a destructor, so that we can expand the stack. Change
YYSTYPE to char * so that we can free it. Cast result of malloc.
(parser::state_type, parser::semantic_type, parser::location_type):
Private, not public.
(parser::parse): Return ints, not bool.
Returning a bool introduces a problem: 0 corresponds to false, and
it seems weird to return false on success. Returning true changes
the conventions for yyparse.
Alternatively we could return void and send an exception.
There is no clear consensus (yet?).
(state_stack, semantic_stack, location_stack): Rename as...
(state_stack_type, semantic_stack_type, location_stack_type): these.
Private, not public.
* tests/c++.at: New.
* tests/testsuite.at, tests/Makefile.am: Adjust.
* data/lalr1.cc (b4_filename_type): New.
(position::filename): Use it.
(parser.hh): Move the inclusion of stack.hh and location.hh below
the user code, so that needed headers for the filename type can be
included first.
Forward declare them before the user code.
* tests/Makefile.am (check-local, installcheck-local): Pass
TESTSUITEFLAGS to the TESTSUITE.
calc" for instance, to extract a sub test suite.
* tests/testsuite.at: Move the initialization, Autotest version
requirement, and AT_TESTED invocation into...
* tests/local.at: here.
* tests/testsuite.at: Include it for compatibility with Autoconf
2.57.
* tests/Makefile.am ($(TESTSUITE)): Report that the warning should
be ignore.
* tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
This new file.
* tests/calc.at (AT_CHECK_CALC): Adjust.
* tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
(AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
* tests/local.at: here.
(AT_COMPILE_CXX): Tags the tests using it as c++.
Ignore the test if CXX is not functional.
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.
newly created state.
Adjust to initialize first_state and last_state if needed.
Be sure to distinguish the initial from the final state.
(new_states): Create the itemset of the initial state, and use
new_state.
* src/closure.c (closure): Now that the initial state has its
items properly set, there is no need for a special case when
creating `ruleset'.
As a result, now the rule 0, reducing to $axiom, is visible in the
outputs. Adjust the test suite.
* tests/conflicts.at (Solved SR Conflicts)
(Unresolved SR Conflicts): Adjust.
* tests/regression.at (Web2c Report, Rule Line Numbers): Idem.
* tests/conflicts.at (S/R in initial): New.
* lib/readpipe.c: New, from wdiff.
* src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
BISON_HAIRY.
* src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
specific values. Now it is m4 that performs the lookup.
* src/parse-skel.y: Remove.
* src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
* src/output.c (actions_output, guards_output)
(token_definitions_output): No longer keeps track of the output
line number, hence remove the second argument.
(guards_output): Check against the guard member of a rule, not the
action member.
Adjust callers.
(output_skeleton): Don't look for the skeleton location, let m4 do
that.
Create `/tmp/muscles.m4'. This is temporary, a proper temporary
file will be used.
Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
(prepare): Given that for the time being changesyntax is not
usable in M4, rename the muscles using `-' to `_'.
Define `defines_flag', `output_parser_name' and `output_header_name'.
* src/output.h (actions_output, guards_output)
(token_definitions_output): Adjust prototypes.
* src/scan-skel.l: Instead of scanning the skeletons, it now
processes the output of m4: `__oline__' and `#output'.
* data/bison.simple: Adjust to be used by M4(sugar).
* tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
to date.
* tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
* data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
shamelessly stolen from CVS Autoconf.
* src/reader.c (readgram): Be sure to attach mid-rule actions to
the empty-rule associated to the dummy symbol, not to the host
rule.
* tests/actions.at (Mid-rule actions): New.
* src/reader.c (symbol_list): `guard' and `guard_line' are new
members.
(symbol_list_new): Adjust.
(copy_action): action_line is the first line, not the last.
(copy_guard): Just as for actions, store the `action' only, not
the switch/case/break flesh.
Don't parse the user action that might follow the guard, let...
(readgram): do it, i.e., now, there can be an action after a
guard.
In other words the guard is just explicitly optional.
(packgram): Adjust.
* src/output.c (guards_output): New.
(output_parser): Call it when needed.
(output): Also free the guard and attrs obstacks.
* src/files.c, src/files.h (obstack_save): Remove.
(output_files): Remove.
As a result, if one needs the former `.act' file, using an
appropriate skeleton which requires actions and guards is now
required.
* src/main.c (main): Adjust.
* tests/semantic.at: New.
* tests/regression.at: Use `input.y' as input file name.
Avoid 8+3 problems by requiring input.c when the test needs the
parser.
RHS's properly.
* tests/torture.at (GNU AWK Grammar): New.
* tests/sets.at (Nullable): New.
* src/nullable.c (set_nullable): Instead of blindly looping over
`ritems', loop over the rules, and then over their rhs's.
Work around Autotest bugs.
* src/warshall.c (bitmatrix_print): Don't use `+--+' as table
frame, because Autotest understand lines starting with a `+' as
traces from the shell. Then, they are not processed properly.
Admittedly an Autotest bug, but we don't have time to wait for
Autotest to catch up.
* tests/regression.at (Broken Closure): Adjust to the new table
frames.
Move to...
* tests/sets.at: here.
