Problem reported by Andy Fiddaman in:
https://lists.gnu.org/r/bug-bison/2019-12/msg00021.html
* data/skeletons/yacc.c (yy_reduce_print, yy_lac, yysyntax_error)
(yyreturn): If I might be a char, write a[+I] instead of a[I],
so that ‘gcc -Wchar-subscripts’ does not complain.
The documentation for Oracle Solaris Studio 12.3 (Sun C++ 5.12
2011/11/16) says it supports C++03. This compiler rejects the
location.cc use of std::max for some reason; I don’t know why
since I don’t use C++ as a rule. The simplest workaround is to
open-code ‘max’.
* data/skeletons/location.cc (add_):
Do max by hand rather than relying on std::max.
Don’t include <algorithm.h>; no longer needed.
As documented in the Autoconf manual, Solaris 10 sed rejects
script labels contianing more than 7 characters. POSIX requires
support for at least 8 characters, but we might as well be portable
to Solaris 10 which is still supported.
* tests/local.at (AT_SETS_CHECK): Use only the first 7 characters
in sed labels.
* src/symtab.c: Include intprops.h
(symbol_user_token_number_set): Don’t allow user_token_number ==
INT_MAX because too much other code adds 1 to the user token number.
(symbols_token_translations_init): Complain on integer overflow
instead of indulging in undefined behavior.
* src/scan-gram.l: Include errno.h, for errno.
(scan_integer, handle_syncline): Check for integer overflow.
* tests/input.at (too-large.y): Adjust to match new diagnostics.
* src/parse-gram.y: Include intprops.h.
(handle_require): Don’t indulge in undefined behavior if the major
or minor number is out of range. Instead, check that the
resulting value is nonnegative, fits in int, and that the minor
number is less than 100. Also, check that a number was parsed.
Sun C 5.12 defines __SUNPRO_C to 0x5120 but diagnoses
‘__attribute__ ((__unused__))’. Change the ifdefs to use
the same method as Gnulib in this area.
* data/skeletons/c.m4 (YY_ATTRIBUTE): Remove, since
not all attributes were added in the same compiler version.
(YY_ATTRIBUTE_PURE, YY_ATTRIBUTE_UNUSED):
Use specific GCC version for each attribute.
Pay no attention to __SUNPRO_C.
* tests/headers.at (Several parsers): Tighten tests accordingly.
Oracle Solaris Studio 12.3 (Sun C 5.12 2011/11/16) by default does
not conform to C99; it defines __STDC_VERSION__ to be 199409L, so
the Bison code does not include <stdint.h> (not required by C89
amendment 1) even though this compiler does have <stdint.h>. On
this platform <limits.h> defines INT_LEAST8_MAX (POSIX allows
this) so the skeleton got confused and thought that <stdint.h> had
been included even though it wasn’t.
* data/skeletons/c.m4 (b4_c99_int_type_define) [!__PTRDIFF_MAX__]:
Always include <limits.h>.
(YY_STDINT_H): Define when <stdint.h> was included.
All uses of expressions like ‘defined INT_LEAST8_MAX’ changed to
‘defined YY_STDINT_H’, since Sun C 5.12 <limits.h> defines macros
like INT_LEAST8_MAX but does not declare types like int_least8_t.
* data/skeletons/c.m4 (b4_c99_int_type_define): Reorder to put the
signed types first, since they’re simpler and this keeps similar
code closer. For signed types, don’t bother checking whether the
type promotes to int since the type must be signed anyway. For
unsigned types, protect a test like ‘UCHAR_MAX <= INT_MAX’ with
‘!defined __UINT_LEAST8_MAX__’, as otherwise the logic is wrong
for oddball platforms; and once we do that, there should no need
for ‘defined INT_MAX’ so remove that.
That way, glr.c can use it too.
* data/skeletons/c.m4 (b4_int_type):
Do not special-case ‘char’; it’s not worth the trouble,
as clang complains about char subscripts.
(b4_c99_int_type, b4_c99_int_type_define): New macros,
taken from yacc.c.
* data/skeletons/glr.c: Use b4_int_type_define.
* data/skeletons/yacc.c (b4_int_type): Remove, since there’s
no longer any need to redefine it.
Use b4_c99_int_type_define rather than its body.
This changes the Yacc skeleton to use “least” integer types to
keep tables smaller on some platforms, which should lessen cache
pressure. Since Bison uses the Yacc skeleton, it follows suit.
* data/skeletons/yacc.c: Include limits.h and stdint.h if this
seems to be needed.
(yytype_uint8, yytype_int8, yytype_uint16, yytype_int16):
If available, use GCC predefined macros __INT_MAX__ etc. to select
a “least” type, as this avoids namespace hassles. Otherwise, if
available fall back on selecting a “least” type via the C99 macros
INT_MAX, INT_LEAST8_MAX, etc. Otherwise, fall further back on one of
the builtin C99 types signed char, short, and int. Make sure that
any selected type promotes to int. Ignore any macros YYTYPE_INT16,
YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8 defined by the user.
(ptrdiff_t, PTRDIFF_MAX): Simplify in the light of the above.
(yytype_uint8, yytype_uint16): Do not assume that unsigned char
and unsigned short promote to int, as this isn’t true on some
platforms (e.g., TI TMS320C55x).
* src/parse-gram.y (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16)
(YYTYPE_UINT8): Remove, as these are no longer effective.
* data/skeletons/yacc.c (YYPTRDIFF_T, YYPTRDIFF_MAXIMUM):
Default to long, not int.
(yy_lac_stack_realloc, yy_lac, yytnamerr, yyparse):
Avoid casts to YYPTRDIFF_T that were masking the problem.
* 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.

Omit now-unnecessary casts.
* data/skeletons/location.cc (b4_location_define):
* doc/bison.texi (Mfcalc Lexer, C++ position, C++ location):
Prefer int to unsigned for line and column numbers.
Change example to abort explicitly on memory exhaustion,
and fix an off-by-one bug that led to undefined behavior.
* data/skeletons/stack.hh (stack::operator[]):
Also allow ptrdiff_t indexes.
(stack::pop, slice::slice, slice::operator[]):
Index arg is now ptrdiff_t, not int.
(stack::ssize): New method.
(slice::range_): Now ptrdiff_t, not int.
* data/skeletons/yacc.c (b4_state_num_type): Remove.
All uses replaced by b4_int_type.
(YY_CONVERT_INT_BEGIN, YY_CONVERT_INT_END): New macros.
(yylac, yyparse): Use them around conversions that -Wconversion
would give false alarms about. Omit unnecessary casts.

a cast that doesn’t seem to be needed here any more.
* examples/c++/variant.yy (yylex):

* src/InadequacyList.c (InadequacyList__new_conflict):

* src/output.c (muscle_insert_unsigned_table):
Remove; no longer used.

* data/skeletons/c.m4 (b4_int_type):

either will do.
* data/skeletons/glr.c (yy_reduce_print): No need to
convert rule line to unsigned long.
(yyrecoverSyntaxError): Put action into an int to
avoid GCC warning of using a char subscript.
* data/skeletons/lalr1.cc (yy_lac_check_, yysyntax_error_):
Prefer ptrdiff_t to size_t.
* data/skeletons/yacc.c (b4_int_type):

* data/skeletons/yacc.c (b4_declare_parser_state_variables):
(YYSTACK_RELOCATE, YYCOPY, yy_lac_stack_realloc, yy_lac)

(yy_reduce_print): Use int instead of unsigned long when int
will do.
(yy_lac_stack_realloc): Prefer long to unsigned long when
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.

(YY_IGNORE_MAYBE_UNINITIALIZED_END, YYLVAL_INITIALIZE):
New macros. Use them to suppress an unwanted GCC diagnostic.

* doc/bison.texinfo (Mid-Rule Actions): Mention that periods and
dashes make symbol names less convenient for named references.

(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

* 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,

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.
instead of from the template, to simplify configuration a bit.
* bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
and m4/wint_t.m4, as they are needed with the latest gnulib.
Problem reported by Joel E. Denny.

(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.
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]>
* bootstrap: Undo last change to this file, since now gnulib-tool
sticks with the automake default in generating dependencies.
(b4_yyssa, b4_yyerror_range): New macros.
(struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
(yypvarsinit): Remove init of removed fields.
(yypushparse): Remove use of removed fields; use new macros instead.
in a push parser. Reindent slightly to match yacc.c better.
2006-10-11 Bob Rossi <[email protected]>
* data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
yymsg_alloc fields.
(yypvarsinit, yypushparse): Remove init of removed fields.
(yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
<http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
and try to make such failures easier to catch in the future.
* data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
that's now the caller's responsibility.
(yyprocessOneStack, yyrecoverSyntaxError, yyparse):
Set yychar = YYEOF if it's negative.
* tests/actions.at (yylex): Abort if asked to read past EOF.
* tests/conflicts.at (yylex): Likewise.
* tests/cxx-type.at (yylex): Likewise.
* tests/glr-regression.at (yylex): Likewise.
* tests/input.at (yylex): Likewise.
* tests/regression.at (yylex): Likewise.
* tests/torture.at (yylex): Likewise.
* bootstrap: Fix bug introduced in recent bootstrap changes, with
respect to bison-runtime pot generation. The YY_ stuff
wasn't being captured.
* bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
* po/POTFILES.in: Add src/location.c, src/scan-code.l.
* runtime-po/POTFILES.in: Add data/push.c.
