* lib/.cvsignore, lib/.gitignore, m4/.cvsignore,
* m4/.gitignore: Regen.
* src/symtab.c (symbol_from_uniqstr, semantic_type_from_uniqstr):
Call xalloc_die on hash_insert failures.
Requested by the new __warn_unused_result__ attribute of
hash_insert.
Its value can be "LALR", "IELR", or "canonical LR".
* lib/timevar.def (TV_IELR_PHASE1): New var.
(TV_IELR_PHASE2): New var.
(TV_IELR_PHASE3): New var.
(TV_IELR_PHASE4): New var.

AnnotationList.h, InadequacyList.c, InadequacyList.h, Sbitset.c,
Sbitset.h, ielr.c, and ielr.h.

trace_types): Add trace_ielr.
* src/lalr.h, src/lalr.c (ngotos): Export it.
(F): Rename to...
(goto_follows): ... this, update all uses, and export it.
(set_goto_map): Export it.
(map_goto): Export it.
(compute_lookahead_tokens): Don't free goto_follows yet. Now
handled in ielr.
(initialize_LA): Export it. Move lookback allocation to...
(lalr): ... here because, for canonical LR, initialize_LA must
be invoked but lookback and much of the rest of LALR isn't
needed.
* main.c (main): Instead of lalr, invoke ielr, which invokes
lalr.
* src/reader.c (reader): Default lr.type to "LALR".
Default lr.default_rules to "accepting" if lr.type is "canonical
LR". Leave the default as "all" otherwise.
Check for a valid lr.type value.

(GNU AWK 3.1.0 Grammar): ... this, and extend to use
AT_TEST_EXISTING_GRAMMAR.
(GNU Cim Grammar): Extend to use AT_TEST_EXISTING_GRAMMAR.

all values of lr.type.
(Single State Split): New test groups using AT_TEST_LR_TYPE.
(Lane Split): Likewise.
(Complex Lane Split): Likewise.
(Split During Added Lookahead Propagation): Likewise.
The real problem is rather gnulib.mk, which itself is extracted from a
Makefile.am that gnulib expects to the "recursive". The tool
prefix-gnulib-mk converts such a gnulib.mk to be non-recursive. Also,
some AC_SUBST variables need to be adjusted.
* etc/prefix-gnulib-mk: New.
* bootstrap (slurp): Use it to convert further gnulib.mk.
* lib/Makefile.am: Rename as...
* lib/local.mk: this.
Adjust to be prefixed.
* Makefile.am, configure.ac: Adjust.
* src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
* HACKING (Administrivia): Make the git-merge-changelog notes more
helpful.
(Test suite): Don't say lalr1.cc is not exercised in the test suite.
(Release Procedure): Update for git and add numerous details that were
previously missing.
* Makefile.am (EXTRA_DIST): Remove Makefile.cfg and Makefile.maint.
* maint.mk (announcement): Don't list bison as a bootstrap tool so
that announcements don't claim we bootstrapped with whatever bison
happened to be in PATH. Add flex as a bootstrap tool.
* Makefile.maint: Remove, previously replaced by maint.mk.
* Makefile.cfg: Remove, and migrate settings to...
* cfg.mk: ... here for the sake of `make announcement'.
* bootstrap.conf (gnulib_modules): Add announce-gen.
* README: Say GNU Bison instead of just Bison. Suggested by Karl
Berry.
* bootstrap (insert_sorted_if_absent): Replace all uses with...
(insert_vc_ignore): ... this new function, which prepends `/' to all
.gitignore entries before passing them to insert_sorted_if_absent.
* bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
.cvsignore files are maintained even though Bison developers run
bootstrap while using Git.
* .cvsignore (*.patch *.log log patches applied): Remove, apparently
unneeded by Bison.
(gnulib): Add.
* .gitignore (/*.patch *.log log patches applied): Remove, broken and
unneeded. Reported by Eric Blake.
* lib/.gitignore (/*~): Add.
* po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
* examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
Blake.
* src/.gitignore (/bison.exe): Add. Reported by Eric Blake.
Reported by Eric Blake at
<http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>.
* bootstrap.conf (gnulib_modules): Add unsetenv.
* lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
* m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
(/setenv.m4): Add.
* src/output.c (output_skeleton): For the m4 invocation, pass -dV as
the first argument because it may become position-dependent, and unset
POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
Add comments explaining these issues in more detail.
in Bison.
* bootstrap: Update gnulib CVS repository URL.
(symlink_to_dir): Encapsulate the code that guarantees the destination
directory exists into...
(check_dst_dir): ... this new function, and...
(cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
fail when copying files into lib/uniwidth/.
* src/output.c (prepare_symbols): When writing yytname muscles, where
symbol names will be encoded in C-string literals, tell quotearg to
escape trigraphs. This used to be the default in gnulib.
* tests/regression.at (Token definitions): Because of the change in
gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
escapes trigraphs in symbol names. Thus, yytname no longer has
trigraphs unnecessarily doubly escaped. Update test case output.
Extend test case to be sure Bison's own error messages will no longer
have trigraphs in symbol names unnecessarily escaped once.
elsewhere.
* src/print-xml.c: Prefer "const" after types; that's more consistent.
(xml_printf): Indent just 1 space for level.
(e_char, xlate_char): Remove.
(xml_escape_string): Rewrite to avoid undefined behavior (used
storage that was freed from the stack).
(xml_escape_n): Don't bother checking for subscript error.

muscle_percent_define_insert and muscle_percent_code_grow when parsing
%define and %code directives.
Make it easy to share %define boolean variables between the front-end
and back-end. Though not used yet, this will be useful in the future.
* data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
Bison uses of names rather than just skeleton uses of names.
(b4_percent_define_get, b4_percent_define_ifdef): Rename

b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
must later be reported as invalid.
* src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
functions.
(muscle_percent_define_insert): Record the location of VARIABLE in
muscle percent_define_loc(VARIABLE), and use it to report the previous
location for a redefinition.

(muscle_percent_define_default): Update like b4_percent_define_default.
(muscle_grow_user_name_list): Rename to...
(muscle_user_name_list_grow): ... this for consistency and use
muscle_location_grow.
* src/muscle_tab.h (muscle_location_grow): Prototype.
* tests/input.at (%define errors): Update expected output.
* tests/skeletons.at (%define boolean variables: invalid skeleton
defaults): New test case.
introduced in the 2007-02-03 change. Bruno Haible reported that
the 2007-02-07 change would be dangerous in Turkish if we add a
language whose name contains "i", since "i" is not lowercase "I"
in Turkish.
* bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
* lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
* m4/.cvsignore: Add strcase.m4.
* src/getargs.c: Revert 2007-02-03 change, as follows.
Don't include c-strcase.h.
(language_argmatch): Use strcasecmp rather than c_strcasecmp.
strcasecmp has "unspecified behavior" outside the POSIX locale,
but it works fine in practice if at least one argument is ASCII,
as is the case in Bison.
the right spot for these files?
* bootstrap.conf (gnulib_modules): Add c-strcase.
* lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
c-strncasecmp.c.
* src/getargs.c: Include c-strcase.h.

instead of passing a yylexp argument to yypull_parse, and don't
generate yypull_parse or yyparse unless %push-pull-parser is declared.
Discussed starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
* data/bison.m4 (b4_pull_if): New.
* data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
* data/push.c: Improve M4 quoting a little.
(b4_generate_macro_args, b4_parenthesize): Remove.
(yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
any time a pull parser is requested.
Don't #define this as a wrapper around yypull_parse. Instead, when
both push and pull are requested, make it a function that does that
same thing.
(yypull_parse): If there's a b4_prefix, #define this to
b4_prefix[pull_parse] when both push and pull are requested.
Don't define this as a function unless both push and pull are
requested.
Remove the yylexp argument and hard-code yylex invocation instead.
* etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
%push-parser.
* src/getargs.c (pull_parser): New global initialized to true.

(prologue_declaration): Set both push_parser and pull_parser = true for
%push-pull-parser. Set push_parser = true and pull_parser = false for
%push-parser.
* src/scan-gram.l: Don't accept %push_parser as an alternative to
%push-parser since there's no backward-compatibility concern here.
Scan %push-pull-parser.
* tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
instead of %push-parser.
* tests/headers.at (export YYLTYPE): Make yylex static, and don't
prototype it in the module that calls yyparse.
* tests/input.at (Torturing the Scanner): Likewise.
* tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
Problem reported by Joel E. Denny.
2006-10-14 Jim Meyering <jim@meyering.net>
(Sync from coreutils.)
Work also when the working directory (with e.g. coreutils sources)
is version controlled with git, rather than CVS.
* bootstrap (CVS_only_file): Test for the existence of README-cvs,
rather than CVS.
In messages and comments, say e.g., "checked-out sources",
rather than "CVS sources".
(version_controlled_file): New function. Work for git as well as
for CVS. Don't use grep's -q option.
(slurp): Call it here, in place of CVS-specific code.
* bootstrap: Sync from coreutils, except add support for gnulib_files.
* bootstrap.conf: New file.
(gnulib_modules): Add configmake, inttypes, unistd.
(XGETTEXT_OPTIONS): Add complain, complain_at,
fatal, fatal_at, warn, warn_at, unexpected_end.
* configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
(gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
(gl_EARLY): Add.
(AM_STDBOOL_H): Remove; gl_INIT now dows this.
(gl_INIT): Add
(GNULIB_AUTOCONF_SNIPPET): Remove.
(AM_GNU_GETTEXT): Add; require formatstring macros since that's
the pickiest.
* lib/.cvsignore: Add inttypes_.h.
* lib/Makefile.am: Include gnulib.mk first so we can append to it.
(AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
(BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
no-longer-necessary initializations.
(lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
* lib/subpipe.c: Include <unistd.h> unconditionally, now that we
use the unistd module.
* src/system.h: Likewise.
* m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
* src/Makefile.am (DEFS): Remove, since configmake does this for us.
(AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
* src/system.h: Include inttypes.h unconditionally, now that we
use the inttypes module. Don't bother to include stdint.h, since
inttypes.h now does that for us.
(LOCALEDIR): Remove, now that we use the configmake module.
* src/getargs.c: Include configmake.h.
* src/main.c: Likewise.
* src/output.c: Likewise.
* tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
not from $abs_top_builddir, since config.h moved.
* bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
Add fopen-safer.
(gnulib_files): Add m4/warning.m4. Don't worry about files
overwritten by autopoint.
Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
Suppress "id", "ms", "tr" translations for now, since gettext 0.15
rejects them.
Don't use autoreconf; instead, invoke autopoint etc. by hand,
so that we can remove the intl files at a better time.
(intl_files_to_remove): Remove aclocal.m4, since it gets
rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.

strdup.h.
* m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
* m4/warning.m4: Remove from CVS, since we now use gnulib's version.
* bootstrap (gnulib_modules): Add stdint.
Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
no longer copies it.
(intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
since stdint needs the former and wcwidth (which is now required
by mbswidth) needs the latter.
Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
work around a compatibility glitch between gettext 0.14.6 and
Autoconf 2.60.
* configure.ac (AC_PREREQ): Require Autoconf 2.60.
Do not check for uintptr_t, since new stdint module does the right
thing.
* lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
Add stdint.h, stdint_.h, wcwidth.h.
* m4/.cvsignore: Remove alloca.m4, onceonly.m4.
Add absolute-header.m4, double-slash-root.m4, longlong.m4,
stdint.m4, wchar_t.m4, wcwidth.m4.
* src/files.c: Include <dirname.h> and <stdio-safer.h> in the
usual order for ../lib/*.h files.
(file_name_split): Use last_component, not base_name, to adjust
to gnulib changes.
* src/parse-gram.h: Include <strverscmp.h> in the usual order
for ../lib/*.h files.
(YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
Define unconditionally, since we now assume the stdint module.
* src/scan-skel.l: Include <dirname.h>.
(BASE_QPUTS): Use last_component, not base_name.
* src/system.h: Include <unlocked-io.h> in the usual order
for ../lib/*.h files. Include <stdint.h> unconditionally,
since we now use the stdint module.
(uintptr_t): Declare if UINTPTR_MAX is not defined, not
HAVE_UINTPTR_T, since we now use the stdint module.
(base_name): Remove decl, since files now include <dirname.h>
to get the decl.
* lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
compilers that don't understand that abort () does not return.
* src/state.c (transitions_to): Likewise.
* m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
that '#include <cstdlib>' works.
* src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
(INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
#undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
for the benefit of some pre-C99 compilers.
* configure.ac: Don't use -Wnested-externs, as it's incompatible
with the new verify.h implementation.
* data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
* data/glr.c (YYUSE): Depend on __GNUC__ as well.
* data/yacc.c (YYUSE): Likewise.
* data/lalr1.cc (yysyntax_error_): YYUSE (yystate).
* lib/subpipe.c (end_of_output_subpipe): The args are unused.
* src/parse-gram.y (declaration): Don't pass a string constant
to a function that expects char *, since GCC might complain
about the constant value.
* src/reader.c (symbol_typed_p): Add parens to pacify GCC.
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
before #defining them.
* tests/glr-regression.at
(Incorrectly initialized location for empty right-hand side in GLR):
In yyerror, use the msg arg.
(Corrupted semantic options if user action cuts parse):
(Incorrect lookahead during deterministic GLR):
(Incorrect lookahead during nondeterministic GLR):
Don't name a local var 'index'; it shadows string.h's 'index'.
GNU/Linux and Solaris that support unlocked I/O. The basic idea
is to use the gnlib unlocked-io module, and to prefer putc and
puts to printf when either will work (since the latter doesn't
come in an unlocked flavor).
* bootstrap (gnulib_modules): Add unlocked-io.
* data/c.m4 (yysymprint): Prefer puts and putc to printf.

* src/getargs.c: Use ARGMATCH_VERIFY rather than verify.
* src/system.h (verify): Remove.
Include verify.h instead.
* src/tables.c (tables_generate): Use new API for 'verify'.
* 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__)).

* 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.
