209 Undo the parts of the unlocked-I/O change that substituted
210 putc or puts for printf. This might hurt performance a bit,
211 but some people prefer the printf style.

242 Use unlocked I/O for a minor performance improvement on hosts like
243 GNU/Linux and Solaris that support unlocked I/O. The basic idea
244 is to use the gnlib unlocked-io module, and to prefer putc and
245 puts to printf when either will work (since the latter doesn't
246 come in an unlocked flavor).
247 * bootstrap (gnulib_modules): Add unlocked-io.
248 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
249 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
250 Prefer them to YYFPRINTF and YYDPRINTF if either will do,
251 and similarly for puts and putc and printf.
252 * data/yacc.c: Likewise.
253 * lib/bitset.c (bitset_print): Likewise.
254 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

256 to printf.

450 Instead, reallocate buffers twice as big each time, so that
451 we waste at most half the allocated memory. Start with a small

828 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
829 now that token names are already quoted.
830
831 Fix problem reported by Anthony Heading.
832 * data/glr.c (YYTOKEN_TABLE): New macro.
833 (yytname): Define if YYTOKEN_TABLE.
834 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
835 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
836 (YYERROR_VERBOSE): Define the same way the other skeletons do.
837 * src/output.c (prepare_symbols): Output token_table_flag.

841 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
842 again if the first call fails.
843
844 * data/glr.c (yytnamerr): New function.
845 (yyreportSyntaxError): Use it to dequote most string literals.
846 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
847 with other skeletons. All uses changed.
848 (yytnameerr_): New function.
849 (yyreport_syntax_error): Use it to dequote most string literals.

852 * doc/bison.texinfo (Decl Summary, Calling Convention):
853 Clarify quoting convention of yytname.
854 * src/output.c (prepare_symbols): Quote all names. This undoes
855 the 2005-04-17 change, which is now accomplished (mostly) via
856 changes in the parsers as described above.
857 * tests/regression.at (Token definitions, Web2c Actions):
858 Undo most 2005-04-17 change here, too.
859
8602005-07-20 Paul Eggert <eggert@cs.ucla.edu>

862 Fix more problems reported by twlevo@xs4all.nl.
863 * tests/cxx-type.at: Don't pipe output of ./types through sed to
864 remove trailing spaces. This loses the exit status of ./types,
865 and isn't needed since ./types shouldn't be emitting trailing
866 spaces.
867 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
868 as the stack isn't valid in that case.
869
870 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):

872 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
873 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
874 is used.
875 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
876 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
877 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
878 Likewise.

880 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
881 overly-picky compilers that reject 'char *foo = "bar";'.
882
883 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
884 to FILE * parameter, not to stderr. This fixes a typo introduced
885 in the 2005-07-12 change.
886
887 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
888 warnings from GCC 4.

899 Destructor cleanups and regularization among the three skeletons.
900 * NEWS: Document the behavior changes.
901 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
902 stack before failing, as the cleanup code will do it for us now.
903 * data/lalr1.cc (yyerrlab): Likewise.
904 * data/glr.c (yyparse): Pop everything off the stack before
905 freeing it, so that destructors get called properly.
906 * data/lalr1.cc (yyreturn): Likewise.
907 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
908 This is more consistent.
909 * doc/bison.texinfo (Destructor Decl): Mention more reasons
910 why destructors might be called. 1.875 -> 2.1.
911 (Destructor Decl, Decl Summary, Table of Symbols):
912 Some English-language cleanups for %destructor.
913 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
914 Add output line for destructor of start symbol.
915 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
916 because of that same extra output line.

918 * NEWS: Document minor wording changes in diagnostics of

921 Remove unused formals. All uses changed.
922 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
923 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
924 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
925 Rename yyoverflowab to yyexhaustedlab.
926 When memory exhaustion occurs during syntax-error reporting,
927 report it separately rather than in a single diagnostic; this
928 eases translation.
929 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
930 (Memory Exhausted): Renamed from Parser Stack Overflow.
931 Revamp wording slightly to prefer "memory exhaustion".
932 * tests/actions.at: "parser stack overflow" -> "memory exhausted".

936 Add i18n support to the GLR skeleton. Partially fix the C++
937 skeleton; a C++ expert needs to finish this. Remove debugging
938 msgids; there's little point to having them translated, since they
939 can be understood only by someone who can read the
940 (English-language) source code.
941
942 Generate runtime-po/bison-runtime.pot automatically, so that we
943 don't have to worry about garbage getting in that file. We'll
944 make sure after the next official release that old msgids don't
945 get lost. See
946 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
947
948 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
949 Now auto-generated.
950 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
951 Fix typos in explanations of the runtime file.
952 * bootstrap: Change gettext keyword from YYI18N to YY_.
953 Use standard Makefile.in.in in runtime-po, since we'll arrange
954 for backward-compatible bison-runtime.po files in a different way.
955 * data/glr.c (YY_): New macro, from yacc.c.
956 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
957 Translate messages intended for users.
958 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
959 the wording in the other skeletons. We don't know that the memory
960 is virtual.
961 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
962 Use same method that yacc.c uses.
963 Don't translate debugging messages.
964 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
965 it doesn't work (yet), and requires C++ expertise to fix.
966 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
967 Move defn to a more logical place, to be consistent with other
968 skeletons.
969 Don't translate debugging messages.
970 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
971 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
972 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
973 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

986 All uses removed.
987 (yyStackOverflow): Just longjmp, but with value 2 so that caller
988 can handle the problem.
989 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
990 (yyparse): New local variable yyresult to record the result.
991 Use result of setjmp to set it, rather than storing itinto
992 struct.
993 (yyDone): Remove label.
994 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
995 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
996 if YYABORT is used).
997 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
998 yyparse status; put status > 1 into diagnostic.
999 Check that status==2 works.
1000 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:

1009 (Exploding the Stack Size with Alloca):

1017 Initialize the line-number information before creating the stack,

2177 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
2178 whether the reducion was empty or not. This leaves room to
2179 improve the use of YYLLOC_DEFAULT in such a case.
2180 lalr1.cc is still experimental, so changing this is acceptable.
2181 And finally, there are probably not many users who changed the
2182 handling of locations in GLR, so changing is admissible too.

2330 AT_BISON_OPTION_PUSHDEFS to get correct help macros.

2332 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
2333 the extra Bison directives instead of the whole series.
2334 Change the grammar so that there are recoverable errors, and
2335 unrecoverable errors. Now we can have the parser give up before
2336 consuming the whole input. As a result we now can observe that
2337 the lookahead is freed when needed.
2338 Change the parser source to parse argv[1] instead of a hard coded
2339 string.
2340 Simplify yylex, and give a value and location to EOF.
2341 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
2342 passed directives already coded in the file.
2343 Add some tests to check the location of "error".
2344 For some tests, the C++ parser is correct, and not yacc.c.
2345 For other tests, they provide different, but unsatisfying, values,
2346 so keep the C++ value so that at least one parser is "correct"
2347 according to the test suite.

2529 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
2530 a seemingly endless set of combinations of versions more recent
2531 than that. The bottom line is that the current sources require
2532 fairly recent versions of the build tools, and it'll be some work

3049 When reducing initial empty rules, Bison parser read an initial
3050 location that is not defined. This results in garbage, and that

3348 The problem was that GLR parsers did not conform to the C standard,
3349 because actions like { $1 = $2 + $3; } expanded to expressions
3350 that invoked YYFILL in separate subexpressions, and YYFILL assigned
3351 to a local variable. The C standard says that expressions
3352 like (var = f ()) + (var = f ()) have undefined behavior.
3353 Another problem was that GCC sometimes issues warnings that
3354 yyfill and its parameters are unused.
3355
3356 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
3357 as possibly unused.
3358 (yyfill): New function.
3359 (YYFILL): Use it.
3360 (yyuserAction): Change type of yynormal to bool, so that it matches
3361 the new yyfill signature. Mark it as possibly unused.
3362
3363
3364 Follow up on a bug I reported in February, where a Bison-generated
3365 parser can loop. Provide a test case and a fix for yacc.c. I
3366 don't have a fix for lalr1.cc or for glr.c, unfortunately.
3367 The original bug report is in:

3369
3370 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
3371 macro's size was becoming unwieldy.
3372 (yyerrlab): Do not discard an empty lookahead symbol, as this
3373 might destroy garbage.
3374 (yyerrorlab): New label, with the old contents of YYERROR,
3375 plus the following change: pop the stack of rhs corresponding
3376 to the production that invoked YYERROR. That is how Yacc
3377 behaves, and POSIX requires this behavior.
3378 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
3379 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
3380 Define 'alarm' to do nothing if unistd.h is not available.
3381 Add a new rule "exp: '-' error;" to test the above change to
3382 data/yacc.c. Use 'alarm' to abort any test taking longer than
3383 10 seconds, as it's probably looping.
3384 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
3385 Also, the new yacc.c generates two fewer diagnostics for an
3386 existing test.

3491 English a bit. Fix fclose typo. Change "const char" to "char
3492 const", and use ANSI C rather than K&R for "main". Suggest
3493 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
3494 and suggest yy_switch_to_buffer.

4014 we don't need to worry about yyerrlab1 being reported as an

4036 popped). This means that the initial elements will not be freed
4037 explicitly, as is the case in yacc.c; it is not a problem, as
4038 these elements have fake values.

4151 'conflict_report'. Translate the entire conflict report at once,
4152 so that we don't assume that "," has the same interpretation in
4153 all languages.

4157 the input file name when not emulating Yacc.

4175 * data/yacc.c (yyparse): New local var yylerrsp, to record the
4176 top of the location stack's error locations.
4177 (yyerrlab): Set it. When discarding a token, push its location
4178 onto yylerrsp so that we don't lose track of the error's end.
4179 (yyerrlab1): Now is only the target of YYERROR, so that we can
4180 properly record the location of the action that failed. For GCC
4181 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
4182 GCC warning about yyerrlab1 being unused if YYERROR is unused.
4183 (yyerrlab2): New label, which yyerrlab now falls through to.
4184 Compute the error's location by applying YYLLOC_DEFAULT to
4185 the locations of all the symbols that went into the error.
4186 * doc/bison.texinfo (Location Default Action): Mention that
4187 YYLLOC_DEFAULT is also invoked for syntax errors.
4188 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

4247 If the user does not define YYSTYPE as a macro, Bison now declares it
4248 using typedef instead of defining it as a macro. POSIX requires this.
4249 For consistency, YYLTYPE is also declared instead of defined.
4250
4251 %union directives can now have a tag before the `{', e.g., the
4252 directive `%union foo {...}' now generates the C code
4253 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
4254 The default union tag is `YYSTYPE', for compatibility with Solaris 9
4255 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
4256 instead of `yyltype'.
4257
4258 `yystype' and `yyltype' are now obsolescent macros instead of being
4259 typedefs or tags; they are no longer documented and will be
4260 withdrawn in a future release.

4266 (YYLTYPE): Renamed from yyltype.
4267 (yyltype, yystype): New (and obsolescent) macros,
4268 for backward compatibility.
4269 * data/yacc.c: Likewise.
4270
4271 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
4272 does not specify a union tag. This is for compatibility with
4273 Solaris 9 yacc.

4275 * src/parse-gram.y (add_param): 2nd arg is now char * not char

4292 has (or usually has) an immediately-following braced code.

4294 to return when scanning braced code.

4363
4364 Remove unportable casts and storage allocation tricks.
4365 While we're at it, remove almost all casts, since they
4366 usually aren't needed and are a sign of trouble.
4367
4368 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
4369
4370 * src/derives.c (derives_compute): Do not subtract NTOKENS from

4400 where it's needed.

4427 var instead of casting to long, to avoid casts.

4439 too much storage.

daa33def 5048 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c

5080 to avoid shadowing warnings by GCC.
5081
5082 * data/glr.c (inline): Remove #define. It's the user's
5083 responsibility to #define it away, just like 'const'.
464c6927 5084 This fixes one of the bugs reported by Nelson H. F. Beebe in
161a71f3 5085 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.

5096 do not confuse xgettext.
5097
5098 * src/struniq.h (struniq_new): Do not declare the return type

5253 Use new @ escapes consistently. Represent brackets with @{ and @}
5254 rather than @<:@ and @:>@, since this works a bit better with dumb
5255 editors like vi. Represent @ with @@, since @ is now consistently
5256 an escape. Use @oline@ and @ofile@ rather than __oline__ and
5257 __ofile__, to avoid unexpected expansions. Similarly, use @output
5258 rather than #output.
5259
5260 * data/c.m4 (b4_copyright): Omit file name from comment, since
5261 the file name could contain "*/".
5262 (b4_synclines_flag): Don't quote the 2nd argument; it should already
5263 be quoted. All uses changed.
5264
5265 * data/glr.c: Use new @ escapes consistently.
5266 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
5267 b4_output_header_suffix, b4_output_header_name, b4_header_guard):

5269 names.

5274 * src/files.h: Likewise.
5275
5276 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
5277 mishandled funny characters in file names, and anyway it isn't
5278 needed any more.
5279 * data/yacc.c: Likewise.
5280 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
5281
5282 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
5283 * data/yacc.c: Likewise.
5284
5285 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
5286 strings now.
5287 (muscle_init): Quote filename as a C string.
5288 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
5289 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
5290 * src/output.c (escaped_file_name_output): New function.
5291 (prepare_symbols): Quote tokens for M4.
5292 (prepare): Don't insert output_infix, output_prefix,
5293 output_parser_name, output_header_name; this is now down by scan-skel.
5294 Insert skeleton as a C string.
5295
5296 * src/output.c (user_actions_output, symbol_destructors_output,
5297 symbol_printers_output): Quote filenames for C and M4.
5298 * src/reader.c (prologue_augment, epilogue_set): Likewise.
5299
5300 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
5301 escapes other than \\ and \'; this simplifies the code.
5302 (<SC_STRING>): Likewise, for \\ and \".
5303 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
5304 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
5305 Use new escapes @{ and @} for [ and ].
5306
5307 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
5308 them with auto vars.
5309 Switch to new escape scheme, where @ is the escape character uniformly.
5310 Abort if a stray escape character is found. Avoid unbounded input
5311 buffer when parsing non-escaped text.
5312
5313 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
5314 __oline__, #output, $@, and @{ do not have unintended meanings.

5321 evaluate to 0 if it's impossible for NINF to be in the respective
5322 table.
5323 (yygetLRActions, yyrecoverParseError): Use them.
5324
5325 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
5326 counted in the token inserted at end of file. Now takes
5327 location_t *, not location_t, so that the location can be
5328 adjusted. All uses changed.
5329
5330 * tests/regression.at (Invalid inputs): Adjust wording in
5331 diagnostic to match the new behavior.
5332
5333 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
5334 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
5335 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
5336 abort ();'. This reduces the runtime of the "Many lookaheads"
5337 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

5346 stack, since the stack was never deeper than 1; instead, use the
5347 new auto var c_context to record the stacked value.
5348
5349 Remove nounput option. At an unexpected end of file, we now unput

5597 indicates one.
5598 * src/output.c (output_skeleton): Use xfclose rather than fclose

5665 The last OS that we could find where this wouldn't work is
5666 SunOS 3.5, and that's too old to worry about now.
5667
5668 * data/glr.c (struct yyltype): Define members even when not
5669 doing locations. This is more consistent with yacc.c, and it
5670 works around the following bug reports:

5684 Be consistent about 'bool'; the old code used an enum in one

5687 * configure.ac (AC_HEADER_STDBOOL): Add.

5713 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
5714 * src/getargs.c (usage): Likewise.
5715
5716 * src/getargs.c (getargs): When there are too few operands, report
5717 the last one. When there are too many, report the first extra
5718 one. This is how diffutils does it.

5730 Include <limits.h> unconditionally, since it's guaranteeed even
5731 for a freestanding C89 compiler.

6042 Let nondeterministic skeletons be usable with deterministic
6043 tables.
6044
6045 With the patch, GAWK compiled by GCC without -O2 passes its test
6046 suite using a GLR parser driven by LALR tables. It fails with -O2
6047 because `struct stat' gives two different answers on my machine:
6048 88 (definition of an auto var) and later 96 (memset on this var).
6049 Hence the stack is badly corrumpted. The headers inclusion is to
6050 blame: if I move the awk.h inclusion before GLR's system header
6051 inclusion, the two struct stat have the same size.

6626 outside the C locale.

6629 this is a GCC extension and is not portable to other compilers.

9413 * src/reader.c (parse_braces): Don't fetch the next char, the
9414 convention is to fetch on entry.

9416 'switch' without a following semicolon.

9428 Creating package.m4 from configure.ac causes too many problems.

9456 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
9457 The ISO C++ standard is extremely clear about it: stderr is
9458 considered a macro, not a regular symbol (see table 94 `Header
9459 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
9460 Therefore std:: does not apply to it. It still does with fprintf.

9471 pure parser and scanner.
9472
9473 * src/parse-skel.y: Request a pure parser, locations, and prefix
9474 renaming.
9475 (%union): Having several members with the same type does not help
9476 type mismatches, simplify.
9477 (YYPRINT, yyprint): New.
9478 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...

9494 Throw away MS-DOS crap: we don't need getpid.
9495 * configure.in: We don't need strndup. It was even causing
9496 problems: because Flex includes the headers *before* us,
9497 _GNU_SOURCE is not defined by config.h, and therefore strndup was
9498 not visible.
9499 * lib/xstrndup.c: New.

9501 Be sure to initialize yylval.muscle member when scanning a MUSCLE.

9512 Include output.h and skeleton.h.
9513 (process_skeleton): Returns void, and takes a single parameter.
9514 * src/scan-skel.l: Add the license notice.
9515 Include skeleton.h.
9516 Don't use %option yylineno: it seems that then Flex imagines
9517 REJECT has been used, and therefore it won't reallocate its
9518 buffers (which makes no other sense to me than a bug). It results
9519 in warnings for `unused: yy_flex_realloc'.

9528 * src/bison.hairy: Add a section directive. Put braces around muscle
9529 names. This parser skeleton is still broken, but Bison should not
9530 choke on a bad muscle 'syntax'.
9531 * src/bison.simple: Add a section directive. Put braces around muscle

9826 (generate_states): Adjust.
9827 * src/print.c: When reporting a rule number to the user, substract
9828 1, so that the axiom rule is rule 0, and the first user rule is 1.

10712 Because useless nonterminals are now kept alive (instead of being

10721 the number of occurrences of each symbol, and later reassigned to
10722 `shift_symbol', containing the symbol that can be shifted from a
10723 given state.
10724 Deobfuscate, i.e., allocate, use and free `symbol_count' here
10725 only, and...
10726 (new_itemsets): Allocate `shift_symbol' here.

13108 The location tracking mechanism is precious for parse error
13109 messages. Nevertheless, it is enabled only when `@n' is used in
13110 the grammar, which is a different issue (you can use it in error
13111 message, but not in the grammar per se). Therefore, there should
13112 be another means to enable it.

13144 Test also `--verbose', `--defines' and `--name-prefix'. Testing
13145 the latter demonstrates a flaw in the handling of non debugging
13146 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
13147 was used in order to simplify:
13148
13149 #if YYDEBUG
13150 if (yydebug)
13151 {
13152 ...
13153 }
13154 #endif
13155
13156 into
13157
13158 if (yydebug)
13159 {
13160 ...
13161 }
13162
13163 unfortunately this leads to a CPP conflict when
13164 `--name-prefix=foo' is used since it produces `#define yydebug
13165 foodebug'.

13215 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
13216 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
13217 difficult and introduced a lot of core dump. It turns out that
13218 Bison used an implementation of `xmalloc' based on `calloc', and
13219 at various places it does depend upon the initialization to 0. I
13220 have not tried to isolate the pertinent places, and all the former
13221 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

14323 (read_declarations): Improve the error message for
14324 an invalid character. Do not abort.
14325 (read_declarations, copy_guard, copy_action): Use
14326 printable_version to avoid unprintable characters in printed output.
14327 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
14328 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
14329 Allow the type of a non-terminal can be given
14330 more than once, as long as all specifications give the same type.
14331
14332 * src/output.c:
14333 (output_headers, output_trailers, output, output_gram)
14334 (output_rule_data): Implement noparserflag variable.
14335 Implement toknumflag variable.
14336 (output): Call reader_output_yylsp to output LTYPESTR.
14337
14338 * src/main.c (main):
14339 If reader sees an error, don't process the grammar.
14340 (fatals): Updated to not use VARARGS1.
14341 (printable_version, int_to_string, warn, warni, warns, warnss)
14342 (warnsss): New error reporting functions. Avoid abort for error.
14343
14344 * src/lex.h:
14345 Added THONG and NOOP for alias processing.

14351 (literalchar); new function to deal with reading \ escapes.
14352 (lex): Use literalchar.
14353 (lex): Implemented "..." tokens.
14354 (literalchar, lex, parse_percent_token): Made tokenbuffer
14355 always contain the token. This includes growing the token
14356 buffer while reading an integer.
14357 (parse_percent_token): Replaced if-else statement with percent_table.
14358 (parse_percent_token): Added % declarations as another
14359 way to specify the flags -n, -l, and -r. Also added hooks for
14360 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
14361 major changes to files.c.
14362 (lex) Retain in the incoming stream a character following
14363 an incorrect '/'.
