* src/location.c (caret_set_file):
* src/scan-code.l (contains_dot_or_dash):
Do not quietly convert pointer to bool, as Oracle Developer Studio
12.6 complains and it is arguably confusing style anyway.
* doc/bison.texi (Mfcalc Symbol Table, Mfcalc Lexer):
Don’t abort on memory allocation failure or integer overflow.
Instead, comment that these things aren’t checked for.
* tests/torture.at (Big horizontal): Adjust to recent changes with
integers. If there are states 0..256, Bison now uses a signed
rather than an unsigned 16-bit integer.
This patch contains more fixes to prefer signed to unsigned
integer types, as modern tools like 'gcc -fsanitize=undefined'
can check for signed integer overflow but not unsigned overflow.
* NEWS: Document the API change.
* boostrap.conf (gnulib_modules): Add intprops.
* data/skeletons/glr.c: Include stddef.h and stdint.h,
since this skeleton can assume C99 or later.
(YYSIZEMAX): Now signed, and the minimum of SIZE_MAX and PTRDIFF_MAX.
(yybool) [!__cplusplus]: Now signed (which is how bool behaves).
(YYTRANSLATE): Avoid use of unsigned, and make the macro
safe even for values greater than UINT_MAX.

Also allow ptrdiff_t indexes.

a cast that doesn’t seem to be needed here any more.

either will do.
* tests/regression.at: Adjust to these changes.
* src/getargs.c (usage): Rely on setlocale (LC_MESSAGES, NULL)
trick only on glibc, as POSIX does not specify the output
of setlocale in this case, and the Gnulib localename module
source code indicates that the trick works only on glibc.
C11 no longer requires support for variable-length arrays, and
VS2015 does not have them. Redo UNIQSTR_CONCAT to use a method
that is simpler and better anyway.
* src/uniqstr.c (uniqstr_vsprintf): Remove; no longer needed.
* src/uniqstr.h (UNIQSTR_GEN_FORMAT, UNIQSTR_GEN_FORMAT_):
* src/uniqstr.c (uniqstr_concat): New function.
* src/uniqstr.h (UNIQSTR_CONCAT): Use it instead of using
uniqstr_vsprintf.
* doc/bison.texi: Add '@documentencoding UTF-8'; needed since the
manual contains UTF-8 characters. This will cause the .info files
to contain UTF-8 quotes and the like, which should be OK nowadays.
Add @documentlanguage while we're at it.
* src/scan-code.l (show_sub_message):
Redo initializations to work around a bogus Sun C 5.12 warning.
(parse_ref): Remove unreachable code that Sun C 5.12 complains about.
* src/uniqstr.h (uniqstr_vsprintf): Use
_GL_ATTRIBUTE_FORMAT_PRINTF (...) instead of __attribute__
((__format__ (__printf__, ...))). Otherwise, Sun C 5.12
complains about an unknown attribute.
* configure.ac (FLEX_CXX_WORKS): New AM_CONDITIONAL.
* examples/calc++/local.mk (examples/calc++/calc++):
Build if FLEX_CXX_WORKS, not BISON_CXX_WORKS.
See http://lists.gnu.org/archive/html/bison-patches/2012-08/msg00024.html
(spreading over September and October).
* data/yacc.c (YY_IGNORE_MAYBE_UNINITIALIZED_BEGIN)
(YY_IGNORE_MAYBE_UNINITIALIZED_END, YYLVAL_INITIALIZE):

* doc/bison.texinfo (Mid-Rule Actions): Mention that periods and
dashes make symbol names less convenient for named references.
* src/scan-code.l:
(handle_action_dollar): New arg textlen. All callers changed.
(handle_action_at): Likewise. Also, args are pointers to const.
(ref_tail_fields): Remove; no longer used.
(letter): Now includes '-' and '.', since this is for Bison
identifiers.
(id): Now the simpler traditional defn, since letters now include
'-' and '.'.
(c_letter, c_id): New defns.
(ref): Use c_id for unbracketed IDs.
(<SC_RULE_ACTION>): Simplify, now that the distinction between
Bison and unbracketed IDs are now in the regular expressions.
(VARIANT_BAD_BRACKETING): Remove.
(VARIANT_NOT_VISIBLE_FROM_MIDRULE): Renumber.
(find_prefix_end): Remove, replacing with ....
(identifier_matches): New function.
(variant_add): Use it. Omit EXPLICIT_BRACKETING arg; no longer
needed. CP arg is pointer to constant. All callers changed.
(show_sub_messages): Remove args CP, EXPLICIT_BRACKETING, DOLLAR_OR_AT.
New arg TEXT. All callers changed. Do not worry about showing
trailing context.
(parse_ref): Args CP, RULE, TEXT are now pointers to const. New
arg TEXTLEN. Remove arg DOLLAR_OR_AT. All callers changed.
Simplify code now that the regular expressions capture the
restrictions.
* src/scan-gram.l (letter, id): Adjust to match scan-code.l.
* src/symlist.c (symbol_list_null): Arg is now pointer to const.
* src/symlist.h: Likewise.
* tests/named-refs.at (Misleading references): These are now caught
by the C compiler, not by Bison; that's good enough. Adjust test
to reflect this.
(Many kinds of errors, Unresolved references): Adjust expected
diagnostics to match new behavior. The same errors are caught,
though the diagnostics are not quite as fancy.
($ or @ followed by . or -): Likewise. Also, Make the grammar
unambiguous, so that diagnostics are not complicated by ambiguity
warnings.
* data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
as they confuse xgettext, which tries to parse them as C character
constants in a preprocessor directive.

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

* src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
* src/muscle_tab.c: Likewise.

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.

* bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
and m4/wint_t.m4, as they are needed with the latest gnulib.

for CVS. Don't use grep's -q option.
(slurp): Call it here, in place of CVS-specific code.
2006-10-11 Paul Eggert <[email protected]>
* bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
variable was sometimes used without being initialized. This
messed up the installation of the INSTALL file in some cases.
2006-10-09 Paul Eggert <[email protected]>
* bootstrap (usage, main program, symlink_to_gnulib): Add option
--copy. Inspired by a suggestion from Bruno Haible.
2006-10-03 Jim Meyering <[email protected]>

(struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
(yypvarsinit): Remove init of removed fields.

Automatically generated dependencies are important even
when all of the sources in a directory come from gnulib.
* bootstrap (gnulib_tool): Remove the "no-dependencies" automake
option that gnulib-tool adds to what becomes our lib/gnulib.mk.
2006-09-23 Jim Meyering <[email protected]>

(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.
<http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
* src/parse-gram.y (symbol_declaration): Don't put statements
before declarations; it's not portable to C89.
* src/scan-code.l (handle_action_at): Likewise.
* src/scan-code.l: Always initialize braces_level; the old code
left it uninitialized and therefore had undefined behavior.
Don't attempt to redefine 'assert', since it runs afoul of
systems where standard headers (mistakenly) include <assert.h>.
Instead, define and use our own alternative, called 'aver'.
* src/reader.c: Don't include assert.h, since we no longer
use assert.
* src/scan-code.l: Likewise.
* src/system.h (assert): Remove, replacing with....
(aver): New function, taking a bool arg. All uses changed.
* src/tables.c (pack_vector): Ensure that aver arg is bool,
not merely an integer.
* data/c.m4 (YYPUSH): New.
(b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
* src/getargs.c (push_parser): New var.
* src/getargs.h (push_parser): New declaration.
* src/output.c (prepare): Add macro insertion of `push_flag'.
* src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
(prologue_declaration): Parse %push-parser.
* src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
* tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
list of removed lines from the traces observed.
(AT_CHECK_CALC_LALR): Added push parser tests.
runtime cost when YYDEBUG is not defined, and so that some tests
that used to fail now work. Problem and initial suggestion by
Paolo Bonzini.
* data/c++.m4 (b4_parse_param_cons): Omit leading ','.
* data/glr.cc (b4_parser_class_name):
Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
(debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
(yydebug_) [YYDEBUG]: New member.
(yycdebug_): Now defined only if YYDEBUG.
* data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
(YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
(b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
if YYYDEBUG.
(debug_stream, set_debug_stream, debug_level, set_debug_level):
Define only if YYDEBUG.
* tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
set_debug_level.
* tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
* tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
AT_CHECK_CALC_GLR_CC that are working now.
before any #includes that we generate, so that feature-test
macros work. Problem reported by Michael Deutschmann in
<http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
* data/lalr1.cc: Likewise.
* doc/bison.texinfo (Prologue): Document that feature-test macros
should be defined before any Bison declarations.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
that depend on location.hh after, not before, Bison decls, since
we now include location.hh after the first user prologue.
