55 Fix infringement on user name space reported by Bruno Haible.
56 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
57 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
58 the user's name space.
59 (alloca): Include <stdlib.h> to get it, if it's not built in.
60 (YYMALLOC, YYFREE): Define only if needed.
61 (malloc, free): Declare, but only if needed, as this infringes on
62 the user name space.

94 Various maintainer cleanups.
95 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
96 conftest*, for benefit of CVS commands run at the same time as
97 "configure". Add build-aux, since "bootstrap" now creates it and
98 its subfiles.
99 * Makefile.cfg (move_if_change): Remove.
100 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
101 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
102 (po_repo, do-po-update, po-update, wget_files, get-targets):
103 (config.guess-url_prefix, config.sub-url_prefix):
104 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
105 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
106 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
107 Remove.
108 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
109 this is now the recommended name.
110 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
111 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
112 ylwrap. These files now go into build-aux.
113 * config/move-if-change: Remove.
114 * config/prev-version.txt: Bump from 1.75 to 2.0.
115

116 * bootstrap: Add stdio-safer, unistd-safer modules.
117 Remove m4/glibc2.m4 (introduced by latest gnulib, but
118 we don't need it).
119 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
120 fopen-safer.c, stdio-safer.h, unistd-safer.h.
121 * lib/subpipe.c: Include "unistd-safer.h".
122 (create_subpipe): Make sure all the newly-created
123 file descriptors are > 2, so that diagnostics don't
124 get sent down them (which might cause Bison to hang, in theory).
125 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
126 * src/files.c (xfopen): Use fopen_safer, not fopen.
127

135 Fix a destructor bug reported by Wolfgang Spraul in
136 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
137 * data/yacc.c (yyabortlab): Don't call destructor, and
138 don't set yychar to EMPTY.
139 (yyoverflowlab): Don't call destructor.
140 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
141 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
142 since we no longer output the message "discarding lookahead token
143 end of input ()".

150 after YY_SYMBOL_PRINT where needed.

152 (struct yyGLRState): Add some comments.
153 (struct yySemanticOption): Add some comments.
154 (union yyGLRStackItem): Add comment.
155

209 From Marcus Holland-Moritz.
210 * data/yacc.c (yyerrlab): Move the code that destroys the stack
211 from here....
212 (yyreturn): to here. That way, destructors are called properly
213 even if the stack overflows, or the user calls YYACCEPT or
214 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
215 (yyoverflowlab): Destroy the lookahead.

223 * NEWS: Bison-generated C parsers no longer quote literal strings
224 associated with tokens.
225 * src/output.c (prepare_symbols): Don't escape strings,
226 since users don't want to see C escapes.
227 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
228 in diagnostics.
c19683bb 229 * tests/input.at (Torturing the Scanner): Likewise.

239
240 * src/parse-gram.y: Include quotearg.h.
241 (string_as_id): Quote $1 before using it as a key, since the
242 lexer no longer quotes it for us.

244 quotes it for us.
245 * src/scan-gram.l: Include quotearg.h.
246 ("\""): Omit quote.
247 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
248 a key, since the rest of the lexer doesn't quote it.
249 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
250 * tests/regression.at (Token definitions): Check for backslashes
251 in token strings.
252
253 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
254 (YYSIZE_T): Define to unsigned long int when using an older compiler.
255 (yyparse): Revamp code to generate long syntax error message, to
256 make it easier to translate, and to avoid problems with arithmetic
257 overflow. Change "virtual memory" to "memory" in diagnostic, since
258 we don't know whether the memory is virtual.

263 translate strings.
264 * data/yacc.c (_) [!defined _]: New macro.
265 All English strings wrapped inside this macro.
266 * doc/bison.texinfo (Bison Parser): Document _.
267 * po/POTFILES.in: Include src/parse-gram.c, since it now
268 includes translateable strings that parse-gram.y doesn't.

280 * tests/regression.at (Token definitions): Don't use a token named
281 c, as that generates a "#define c ..." that runs afoul of buggy
282 stdlib.h that uses the identifier c as a member of struct
283 drand48_data. Problem reported by Horst Wente.

327 Escape symbol tags too.

542 Remove uses of 'short int' and 'unsigned short int'. This raises

547 task, as some users will want to conserve memory there.

549 Ideally we should use size_t to represent all object counts, and

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

1103 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
1104 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
1105 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
1106 the extra Bison directives instead of the whole series.
1107 Change the grammar so that there are recoverable errors, and
1108 unrecoverable errors. Now we can have the parser give up before
1109 consuming the whole input. As a result we now can observe that
1110 the lookahead is freed when needed.
1111 Change the parser source to parse argv[1] instead of a hard coded
1112 string.
1113 Simplify yylex, and give a value and location to EOF.
1114 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
1115 passed directives already coded in the file.
1116 Add some tests to check the location of "error".
1117 For some tests, the C++ parser is correct, and not yacc.c.
1118 For other tests, they provide different, but unsatisfying, values,
1119 so keep the C++ value so that at least one parser is "correct"
1120 according to the test suite.

1300 Spent a few hours checking out which prerequisite versions the
1301 current sources actually require. I went all the way back to
1302 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
1303 a seemingly endless set of combinations of versions more recent
1304 than that. The bottom line is that the current sources require
1305 fairly recent versions of the build tools, and it'll be some work
1306 to change this.
1307 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
1308 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.

2119 Fix a GLR parser bug I reported in February; see

2121 The problem was that GLR parsers did not conform to the C standard,
2122 because actions like { $1 = $2 + $3; } expanded to expressions
2123 that invoked YYFILL in separate subexpressions, and YYFILL assigned
2124 to a local variable. The C standard says that expressions
2125 like (var = f ()) + (var = f ()) have undefined behavior.
2126 Another problem was that GCC sometimes issues warnings that
2127 yyfill and its parameters are unused.
2128
2129 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
2130 as possibly unused.
2131 (yyfill): New function.
2132 (YYFILL): Use it.
2133 (yyuserAction): Change type of yynormal to bool, so that it matches
2134 the new yyfill signature. Mark it as possibly unused.
2135
2136
2137 Follow up on a bug I reported in February, where a Bison-generated
2138 parser can loop. Provide a test case and a fix for yacc.c. I
2139 don't have a fix for lalr1.cc or for glr.c, unfortunately.
2140 The original bug report is in:

2142
2143 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
2144 macro's size was becoming unwieldy.
2145 (yyerrlab): Do not discard an empty lookahead symbol, as this
2146 might destroy garbage.
2147 (yyerrorlab): New label, with the old contents of YYERROR,
2148 plus the following change: pop the stack of rhs corresponding
2149 to the production that invoked YYERROR. That is how Yacc
2150 behaves, and POSIX requires this behavior.
2151 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
2152 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
2153 Define 'alarm' to do nothing if unistd.h is not available.
2154 Add a new rule "exp: '-' error;" to test the above change to
2155 data/yacc.c. Use 'alarm' to abort any test taking longer than
2156 10 seconds, as it's probably looping.
2157 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
2158 Also, the new yacc.c generates two fewer diagnostics for an
2159 existing test.

2166 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM

2787 we don't need to worry about yyerrlab1 being reported as an
2788 "unused label" by non-GCC C compilers. The downside is that if
2789 locations are used then a couple of statements are duplicated each
2790 time YYERROR is invoked, but the upside is that the warnings
2791 should vanish.
2792 (yyerrlab1): Move code to YERROR.

2806 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
2807 when the stacks contain one element, as the loop would otherwise
2808 free the last state, and then use the top state (the one we just
2809 popped). This means that the initial elements will not be freed
2810 explicitly, as is the case in yacc.c; it is not a problem, as
2811 these elements have fake values.

2924 'conflict_report'. Translate the entire conflict report at once,
2925 so that we don't assume that "," has the same interpretation in
2926 all languages.
2927 (conflicts_output): Use Yacc-style conflict report for each state,
2928 instead of our more-complicated style.
2929 (conflicts_print): Use Yacc-style conflict report, except print
2930 the input file name when not emulating Yacc.

2948 * data/yacc.c (yyparse): New local var yylerrsp, to record the
2949 top of the location stack's error locations.
2950 (yyerrlab): Set it. When discarding a token, push its location
2951 onto yylerrsp so that we don't lose track of the error's end.
2952 (yyerrlab1): Now is only the target of YYERROR, so that we can
2953 properly record the location of the action that failed. For GCC
2954 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
2955 GCC warning about yyerrlab1 being unused if YYERROR is unused.
2956 (yyerrlab2): New label, which yyerrlab now falls through to.
2957 Compute the error's location by applying YYLLOC_DEFAULT to
2958 the locations of all the symbols that went into the error.
2959 * doc/bison.texinfo (Location Default Action): Mention that
2960 YYLLOC_DEFAULT is also invoked for syntax errors.
2961 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

3020 If the user does not define YYSTYPE as a macro, Bison now declares it
3021 using typedef instead of defining it as a macro. POSIX requires this.
3022 For consistency, YYLTYPE is also declared instead of defined.
3023
3024 %union directives can now have a tag before the `{', e.g., the
3025 directive `%union foo {...}' now generates the C code
3026 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
3027 The default union tag is `YYSTYPE', for compatibility with Solaris 9
3028 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
3029 instead of `yyltype'.
3030
3031 `yystype' and `yyltype' are now obsolescent macros instead of being
3032 typedefs or tags; they are no longer documented and will be
3033 withdrawn in a future release.

3040 (yyltype, yystype): New (and obsolescent) macros,
3041 for backward compatibility.
3042 * data/yacc.c: Likewise.
3043

3045 does not specify a union tag. This is for compatibility with
3046 Solaris 9 yacc.

3065 has (or usually has) an immediately-following braced code.

3067 to return when scanning braced code.

3097 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
3098 as the caller now does that.

3100 (YYEMPTY): Parenthesize right hand side, since others use it.
3101 (yyparse): Don't assume that our generated code is the only code
3102 that sets yychar.

3136
3137 Remove unportable casts and storage allocation tricks.
3138 While we're at it, remove almost all casts, since they
3139 usually aren't needed and are a sign of trouble.
3140
3141 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
3142
3143 * src/derives.c (derives_compute): Do not subtract NTOKENS from
3144 the pointer DSET returned by malloc; this isn't portable.
3145 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
3146 Similarly for DERIVES.
3147 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
3148 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
3149 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
3150
3151 * src/derives.c (derives_compute): Do not bother invoking
3152 int_of_rule_number, since rule numbers are integers.
3153
3154 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
3155 rather than XMALLOC (char, N).
3156
3157 * src/files.c (filename_split): Rewrite to avoid cast.
3158
3159 * src/gram.h (symbol_number_as_item_number,
3160 item_number_as_symbol_number, rule_number_as_item_number,
3161 item_number_as_rule_number):
3162 Now inline functions rather than macros, to avoid casts.
3163 * src/state.h (state_number_as_int): Likewise.
3164 * src/tables.c (state_number_to_vector_number,
3165 symbol_number_to_vector_number): Likewise.
3166
3167 * src/gram.h (int_of_rule_number): Remove; no longer used.
3168
3169 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
3170 since the resulting storage is always stored into.
3171
3172 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
3173 where it's needed.
3174
3175 * src/muscle_tab.c (muscle_m4_output):
3176 Now inline. Return bool, not int.
3177 * src/state.c (state_compare): Likewise.

3187 symbol_check_alias_consistency_processor, symbol_pack_processor,
3188 symbol_translation_processor, hash_symbol_comparator,
3189 hash_symbol_hasher): Likewise.
3190 * src/uniqstr.c (uniqstr_print_processor): Likewise.
3191 * src/muscle_tab.c (muscles_m4_output):
3192 Use new functions instead of casting old functions unportably.
3193 * src/state.c (state_hash_new): Likewise.
3194 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
3195 symbols_token_translations_init):
3196 Likewise.
3197 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
3198
3199 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
3200 var instead of casting to long, to avoid casts.
3201 (prepare_states): Use MALLOC rather than alloca, so that we don't
3202 have to worry about alloca.
3203 * src/state.c (state_hash_lookup): Likewise.
3204
3205 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
3206 local var instead of casting to unsigned char, to avoid casts.
3207
3208 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
3209 STATE_ALLOC): Remove.
3210 (transitions_new, errs_new, reductions_new, state_new): Use malloc
3211 rather than calloc, and use offsetof to avoid allocating slightly
3212 too much storage.
3213 (state_new): Initialize all members.
3214
3215 * src/state.c (state_hash): Use unsigned accumulator, not signed.
3216
3217 * src/symtab.c (symbol_free): Remove; unused.
3218 (symbol_get): Remove cast in lhs of assignment.
3219 (symbols_do): Now static. Accept generic arguments, not
3220 hashing-related ones.
3221
3222 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
3223 (symbol_processor): Remove.
3224 (symbols_do): Remove decl; now static.
3225
3226 * src/system.h (alloca): Remove; decl no longer needed.
3227 (<stddef.h>): Include, for offsetof.
3228 (<inttypes.>, <stdint.h>): Include if available.
3229 (uintptr_t): New type, if system lacks it.
3230 (CALLOC, MALLOC, REALLOC): New macros.
3231 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
3232 new macros.
3233
3234 * src/tables.c (table_size): Now int, to pacify GCC.
3235 (table_grow, table_ninf_remap): Use signed table size.
3236 (save_row): Don't bother initializing locals when not needed.
3237 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.

3239
3240 * src/vcg.h: Correct misspellings.
3241
3242 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
3243
3244
3245 * src/getargs.c (getargs): Don't assume EOF == -1.

3249 Change identifier spellings to avoid collisions with names
3250 that are reserved by POSIX.
3251
3252 Don't use names ending in _t, since POSIX reserves them.
3253 For consistency, remove _e and _s endings -- they're weren't
3254 needed to remove ambiguity. All uses changed.
3255 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
3256 turn was just renamed from struniq_t.
3257 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
3258 which in turn was just renamed from struniq_processor_t.

3397 then the . include files in double-quotes (alphabetized). Fix
3398 dependency breakages encountered in this process, as follows:

4026 Use new @ escapes consistently. Represent brackets with @{ and @}
4027 rather than @<:@ and @:>@, since this works a bit better with dumb
4028 editors like vi. Represent @ with @@, since @ is now consistently
4029 an escape. Use @oline@ and @ofile@ rather than __oline__ and
4030 __ofile__, to avoid unexpected expansions. Similarly, use @output
4031 rather than #output.
4032
4033 * data/c.m4 (b4_copyright): Omit file name from comment, since
4034 the file name could contain "*/".

4081 them with auto vars.
4082 Switch to new escape scheme, where @ is the escape character uniformly.
4083 Abort if a stray escape character is found. Avoid unbounded input
4084 buffer when parsing non-escaped text.

4099 counted in the token inserted at end of file. Now takes

4325 Check for overflow here.
4326 Allow \? and UCNs, for compatibility with C.

4329 with quote slot used by complain_at.

4331 * tests/input.at: Add tests for backslash-newline, m4 quotes
4332 in symbols, long literals, and funny escapes in strings.

4358 escape "[" as "@<:@" and likewise for "]".

4366 Check for close failures.
4367 * src/files.h (xfclose): Return void, not int, since it always
4368 returned zero.
4369 * src/files.c (xfclose): Likewise. Report I/O error if ferror
4370 indicates one.
4371 * src/output.c (output_skeleton): Use xfclose rather than fclose

4373

4395 we use malloc. Don't assume 'A' through 'Z' are contiguous.

4418 non-fatal error occurs. Formerly, the times were reported in some
4419 such cases but not in others.

4436 decl; not needed any more.
4437 * src/main.c (main): Use return to exit, undoing yesterday's change.
4438 The last OS that we could find where this wouldn't work is
4439 SunOS 3.5, and that's too old to worry about now.
4440
4441 * data/glr.c (struct yyltype): Define members even when not
4442 doing locations. This is more consistent with yacc.c, and it
4443 works around the following bug reports:

4457 Be consistent about 'bool'; the old code used an enum in one

4459 * m4/stdbool.m4: New file, from coreutils 4.5.3.
4460 * configure.ac (AC_HEADER_STDBOOL): Add.
4461 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

4484 What was that "2" for?

4486 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
4487 * src/getargs.c (usage): Likewise.
4488
4489 * src/getargs.c (getargs): When there are too few operands, report
4490 the last one. When there are too many, report the first extra
4491 one. This is how diffutils does it.

4503 Include <limits.h> unconditionally, since it's guaranteeed even
4504 for a freestanding C89 compiler.

4815 Let nondeterministic skeletons be usable with deterministic
4816 tables.
4817
4818 With the patch, GAWK compiled by GCC without -O2 passes its test
4819 suite using a GLR parser driven by LALR tables. It fails with -O2
4820 because `struct stat' gives two different answers on my machine:
4821 88 (definition of an auto var) and later 96 (memset on this var).
4822 Hence the stack is badly corrumpted. The headers inclusion is to
4823 blame: if I move the awk.h inclusion before GLR's system header
4824 inclusion, the two struct stat have the same size.

4878 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

5052 signifies end-of-input. Warn about negative chars. Mention
5053 the portable Standard C character set.

5055 The GNU coding standard says CFLAGS and YFLAGS are reserved
5056 for the installer to set.

5393 to void, to avoid a GCC warning when --disable-nls is in effect.
5394
5395 * src/scan-gram.l: Use strings rather than escapes when possible,
5396 to minimize the number of warnings from xgettext.
5397 (handle_action_dollar, handle_action_at): Don't use isdigit,
5398 as it mishandles negative chars and it may not work as expected
5399 outside the C locale.
5400
5401 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
5402 this is a GCC extension and is not portable to other compilers.

8269 problems: because Flex includes the headers *before* us,
8270 _GNU_SOURCE is not defined by config.h, and therefore strndup was
8271 not visible.
8272 * lib/xstrndup.c: New.
8273 * src/scan-skel.l: Use it.
8274 Be sure to initialize yylval.muscle member when scanning a MUSCLE.

8289 Don't use %option yylineno: it seems that then Flex imagines
8290 REJECT has been used, and therefore it won't reallocate its
8291 buffers (which makes no other sense to me than a bug). It results
8292 in warnings for `unused: yy_flex_realloc'.

8599 (generate_states): Adjust.
8600 * src/print.c: When reporting a rule number to the user, substract
8601 1, so that the axiom rule is rule 0, and the first user rule is 1.

8637 Be sure to preserve the value of the eoftoken.
8638 (reader): Make sure eoftoken is defined.
8639 Initialize nsyms to 0: now eoftoken is created just like the others.
8640 * src/print.c (print_grammar): Don't special case the eof token.
8641 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
8642 lie anyway, albeit pleasant.
8643 * tests/calc.at: Exercise error messages with eoftoken.
8644 Change the grammar so that empty input is invalid.

8736 the switch/case/break flesh.
8737 Don't parse the user action that might follow the guard, let...

8784 `lookaheadsp' member of the following state (since lookaheads of

9644 an arbitrary restriction on hosts where size_t is wider than int.

9646 (yyparse): Don't dump core if alloca or malloc fails; instead, report
9647 a parser stack overflow. Allocate just one block of memory for all
9648 three stacks, instead of allocating three blocks; this typically is
9649 faster and reduces fragmentation.
9650
9651 Do not limit the number of items in the stack to a value that fits

11988 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
11989 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
11990 difficult and introduced a lot of core dump. It turns out that
11991 Bison used an implementation of `xmalloc' based on `calloc', and
11992 at various places it does depend upon the initialization to 0. I
11993 have not tried to isolate the pertinent places, and all the former
11994 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
11995 someone should address this issue.

12365 Change the handling of @s so that they behave exactly like $s.
12366 There is now a pseudo variable @$ (readble and writable), location
12367 of the lhs of the rule (by default ranging from the location of
12368 the first symbol of the rhs, to the location of the last symbol,
12369 or, if the rhs is empty, YYLLOC).
12370
12371 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
12372 yyval.
12373 (yyparse): When providing a default semantic action, provide a
12374 default location action.
12375 (after the $): No longer change `*YYLSP', just stack YYLOC the
12376 same way you stack YYVAL.
12377 * src/reader.c (read_declarations): Use warns.
12378 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
12379 (copy_action, case '@'): Likewise.

12381 translators.

13132 way to specify the flags -n, -l, and -r. Also added hooks for
