103 there.
104 * NEWS (2.5): Tweak wording of lr.type and parse.lac entries a
105 bit, update the cross-references to the manual, and point out that
106 LAC has caveats. Don't be so adamant that IELR+LAC=canonical LR.
107 That is, as the referenced section in the manual documents, LAC
108 does not fix infinite parsing loops on syntax errors.
109 * doc/bison.texinfo: Consistently drop the "(1)" suffix from LALR,
110 IELR, and LR in @cindex.
111 (%define Summary): Condense the entries for lr.default-reductions,
112 lr.keep-unreachable-states, lr.type, and parse.lac into brief
113 summaries, and cross-reference the appropriate subsections of
114 Tuning LR. For parse.lac, mention that it's only implemented for
115 deterministic parsers in C. In parse.error entry, mention LAC,
116 and add cross-reference to the LAC section.
117 (Error Reporting): When mentioning parse.error, mention LAC, and
118 add cross-reference to the LAC section.
119 (Tuning LR): New section with an extended version of the

205 doc: clean up naming of various Bison files.
206 The Bison manual's names for various files associated with a Bison
207 parser has devolved into inconsistency. This patch makes the
208 naming consistent for the most important files. First, it chooses
209 "grammar file" over "input file". The former appears to be more
210 traditional in the Bison manual, and Bison has other input
211 files (skeletons). Second, it chooses "parser implementation
212 file" over names like "parser file", "parser source file", "parser
213 source code file", and "parser output file". The new name makes
214 it clearer where Bison generates the main parser implementation,
215 and it is easily distinguishable from "parser header file".
216 * doc/bison.texinfo: Implement throughout.

229 * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
230 LR(1) are experimental. Mention Java. Normally experimental
231 features probably shouldn't be mentioned in the introduction.
232 However, if Bison's limitations to LALR(1), C, and C++ are so
233 important that they should be mentioned here, then it's important
234 to point out that Bison is beginning to escape those limitations.
235 Moreover, these particular experimental features have very little
236 chance of being removed.
237 * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
238 experimental.

242 Do not allow identifiers that start with a dash.
243 This cleans up our previous fixes for a bug whereby Bison
244 discarded `.field' in `$-1.field'. The previous fixes were less
245 restrictive about where a dash could appear in an identifier, but
246 the restrictions were hard to explain. That bug was reported and
247 this final fix was originally suggested by Paul Hilfinger. This
248 also fixes a remaining bug reported by Paul Eggert whereby Bison
249 parses `%token ID -123' as `%token ID - 123' and handles `-' as an
250 identifier. Now, `-' cannot be an identifier. Discussed in
251 threads beginning at
252 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
253 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
254 * NEWS (2.5): Update entry describing the dash extension to
255 grammar symbol names. Also, move that entry before the named
256 references entry because the latter mentions the former.
257 * doc/bison.texinfo (Symbol): Update documentation for symbol
258 names. As suggested by Paul Eggert, mention the effect of periods
259 and dashes on named references.
260 (Decl Summary): Update documentation for unquoted %define values,
261 which, as a side effect, can no longer start with dashes either.
262 * src/scan-code.l (id): Implement.

289 Improve error messages for `$' or `@' followed by `.' or `-'.
290 Previously, for this special case of an invalid reference, the
291 usual "symbol not found in production:" was printed. However,
292 because the symbol name was parsed as the empty string, that
293 message was followed immediately by a newline instead of a symbol
294 name. In reality, this is a syntax error, so the reference is
295 invalid regardless of the symbols actually appearing in the
296 production. Discussed at
297 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
298 * src/scan-code.l (parse_ref): Report the above case as a syntax
299 error. Other than that, continue to handle this case like any
300 other invalid reference that Bison manages to parse because
301 "possibly meant" messages can still be helpful to the user.

425 However, one point there must be corrected: because of %nonassoc,
426 LAC is *not* always redundant for lr.type=canonical-lr.
427 * data/yacc.c: Accept values of "none" (default) or "full" for
428 parse.lac. Accept %define parse.lac.es-capacity to specify
429 capacity of LAC's temporary exploratory stack. It defaults to 20

435 yy_lac and track when it needs to be invoked
436 (yy_lac): New function that, given the current stack, determines
437 whether a token can eventually be shifted. Return status mimics
438 yyparse return status.
439 (yysyntax_error): Change yystate argument to yyssp so stack top
440 can be passed to yy_lac. If LAC is requested, build expected
441 token list by invoking yy_lac for every token instead of just
442 checking the current state for lookaheads. Return 2 if yy_lac
443 exhausts memory.
444 (yyparse, yypush_parse): Use local variable yy_lac_established and
445 cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
446 Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
447 is requested.
448 * tests/conflicts.at (%nonassoc and eof): Extend to check the
449 effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
450 (parse.error=verbose and consistent errors): Likewise.
451 (LAC: %nonassoc requires splitting canonical LR states): New test
452 group demonstrating how LAC can fix canonical LR.

468 yysyntax_error: fix for consistent error with lookahead.
469 * NEWS (2.5): Document.
470 * data/yacc.c (yysyntax_error): In a verbose syntax error
471 message while in a consistent state with a default action (which
472 must be an error action given that yysyntax_error is being
473 invoked), continue to drop the expected token list, but don't
474 drop the unexpected token unless there actually is no lookahead.
475 Moreover, handle that internally instead of returning 1 to tell
476 the caller to do it. With that meaning of 1 gone, renumber
477 return codes more usefully.
478 (yyparse, yypush_parse): Update yysyntax_error usage. Most
479 importantly, set yytoken to YYEMPTY when there's no lookahead.
480 * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
481 unexpected token unless there actually is no lookahead.
482 * data/lalr1.cc (yy::parser::parse): If there's no lookahead,
483 pass yyempty_ not yyla.type to yysyntax_error_.
484 (yy::parser::yysyntax_error_): Again, don't drop the unexpected
485 token unless there actually is no lookahead.
486 * data/lalr1.java (YYParser::parse): If there's no lookahead,
487 set yytoken to yyempty_ before invoking yysyntax_error.
488 (YYParser::yysyntax_error): Again, don't drop the unexpected
489 token unless there actually is no lookahead.
490 * tests/conflicts.at (parse.error=verbose and consistent
491 errors): Extend test group to further reveal how the previous
492 use of the simple "syntax error" message was too general. Test
493 yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
494 failure.
495 * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
496 to...

498 (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.

564 * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
565 anymore and don't know of anybody else who does. If someone needs
566 these files, they can resurrect them.
567 * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
568 * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
569 Omit leading '/', since bootstrap omits it.
570 Adjust file names to match current contents better.
571 * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
572 installed just for us.
573 * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
574 glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
575 needed somehow. Don't have time to look into why.
576 (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
577 the GNU malloc behavior, where malloc (0) != NULL unless we're
578 out of storage? If not, we can omit malloc-gnu; but for now I left
579 it in to be safe.
580 (vc_ignore): Remove.

1092 portability: fix several issues with M4 subprocess.
1093
1094 M4's output pipe was not being drained upon fatal errors during
1095 scan_skel. As a result, broken-pipe messages from M4 were seen
1096 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
1097 failure in the test suite. The problem was that, on platforms
1098 where the default disposition for SIGPIPE is ignore instead of
1099 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
1100 then reported it. However, there's some sort of race condition,
1101 because the new test group occasionally succeeded.

1251 portability: `<' and `>' are not always defined on addresses.
1252 Specifically, don't sort objects by their memory addresses when

1255 says the behavior is undefined.

1276 Fix handling of yychar manipulation in user semantic actions.
1277 The problem was that yacc.c didn't always update the yychar
1278 translation afterwards. However, other skeletons appear to be
1279 fine. glr.c appears to already translate yychar before every
1280 use. lalr1.cc does not define yychar and does not document its
1281 replacement, yyla, for users. It does provide yyclearin, but
1282 that does not manipulate yyla and thus requires no translation
1283 update. In lalr1.java, yychar is out of scope during semantic
1284 actions.
1285 * NEWS (2.5): Document.
1286 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
1287 yytoken here.
1288 (yyparse, yypush_parse): Instead, translate before every use of
1289 yytoken, and add comments explaining this approach.
1290 * tests/actions.at (Destroying lookahead assigned by semantic
1291 action): New test group checking that translation happens before
1292 lookahead destructor calls at parser return. Previously,
1293 incorrect destructors were called.
1294 * tests/conflicts.at (parse.error=verbose and consistent
1295 errors): New test group checking that translation happens at
1296 syntax error detection before the associated verbose error
1297 message and the associated lookahead destructor calls. While
1298 the destructor call is fixed by this patch, the verbose error
1299 message is currently incorrect due to another bug (see
1300 comments in test group), so this is an expected failure for now.

1493 yysyntax_error: avoid duplicate lookahead collection.
1494 Except when memory reallocation is required, this change
1495 eliminates the need to invoke yysyntax_error twice and thus to
1496 repeat the collection of lookaheads. It also prepares for
1497 future extensions that will make those repetitions more

1663 It is common to use sort of factories in the user actions. These
1664 factories may check some "syntactic" constraints that are not

1883 (yygetLRActions): Check for default value from yypact. It
1884 appears that this check is always performed before this function
1885 is invoked, and so adding the check here is probably redundant.
1886 However, the code may evolve after this subtlety is forgotten.
1887 Also, update for rename to yytable_value_is_error. Because that

2119 build: fix the generation of the documentation.
2120 Some of our targets use "bison --help", but they can't depend on
2121 "bison" itself (to avoid additional requirements on the user), so
2122 they used to call "make src/bison" in the commands. Then
2123 concurrent builds may fail: one make might be aiming one of its
2124 jobs at compiling src/bison, and another job at generating the man
2125 page. If the latter is faster than the former, then we have two
2126 makes that concurrently try to compile src/bison.
2127

4236 Finer input type for yytranslate.
4237 This patch is debatable: the tradition expects yylex to return an int
4238 which happens to correspond to token_number (which is an enum). This
4239 allows for instance to return characters (such as '*' etc.). But this
4240 goes against the stronger typing I am trying to have with the new
4241 lex interface which return a symbol_type. So in this case, feed
4242 yytranslate_ with a token_type.

4419 Introduce make_symbol.
b06df3c2
AD
4420 make_symbol provides a means to construct a full symbol (kind,
4421 value, location) in a single shot. It is meant to be a Symbol
4422 constructor, parameterized by the symbol kind so that overloading
4423 would prevent incorrect kind/value pairs. Unfortunately
4424 parameterized constructors do not work well in C++ (unless the
4425 parameter also appears as an argument, which is not acceptable),
4426 hence the use of a function instead of a constructor.

4641 Change the handling of the symbols in the skeletons.
4642 Before we were using tables which lines were the symbols and which
4643 columns were things like number, tag, type-name etc. It is was
4644 difficult to extend: each time a column was added, all the numbers had
4645 to be updated (you asked for colon $2, not for "tag"). Also, it was
4646 hard to filter these tables when only a subset of the symbols (say the
4647 tokens, or the nterms, or the tokens that have and external number
4648 *and* a type-name) was of interest.
de62edee 4649
d69c9694
AD
4650 Now instead of monolithic tables, we define one macro per cell. For
4651 instance "b4_symbol(0, tag)" is a macro name which contents is
4652 self-decriptive. The macro "b4_symbol" provides easier access to
4653 these cells.

4976 Unfortunately this uncovered a bug in the C++ parser itself: the
4977 lookahead value was not destroyed between two calls to yylex. For
4978 instance if the previous lookahead was a std::string, and then an int,
4979 then the value of the std::string was correctly taken (i.e., the
4980 lookahead was now an empty string), but std::string structure itself
4981 was not reclaimed.
de62edee 4982
2d32fc9f
AD
4983 This is now done in variant::build(other&) (which is used to take the
4984 value of the lookahead): other is not only stolen from its value, it
4985 is also destroyed. This incurs a new performance penalty of a few
4986 percent, and union becomes faster again.

5267 Fuse the three stacks into a single one.
de62edee 5268
b06df3c2
AD
5269 In order to make it easy to perform benchmarks to ensure that
5270 there are no performance loss, lalr1.cc is forked into
5271 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
5272 lalr1.cc.
5273
5274 Meanwhile, to make sure that lalr1-fusion.cc is correctly
5275 exercized by the test suite, the user must install a symbolic link
5276 from lalr1.cc to it.

5278 Instead of having three stacks (state, value, location), use a
5279 stack of triples. This considerably simplifies the code (and it
5280 will be easier not to require locations as currently does the C++
5281 parser), and also gives a 10% speedup according to
5282 etc/bench (probably mainly since memory allocation is done once
5283 instead of three times).

5285 Another motivation is to make it easier to destruct properly
5286 semantic values: now that they are bound to their state (hence
5287 symbol type) it will be easier to call the appropriate destructor.

5334 Use variants to support objects as semantic values.
b06df3c2
AD
5335 This patch was inspired by work by Michiel De Wilde. But he used
5336 Boost variants which (i) requires Boost on the user side, (ii) is
5337 slow, and (iii) has useless overhead (the parser knows the type of
5338 the semantic value there is no reason to duplicate this
5339 information as Boost.Variants do).
5340
5341 This implementation reserves a buffer large enough to store the
5342 largest objects. yy::variant implements this buffer. It was
5343 implemented with Quentin Hocquet.

5902 directory exists into...
5903 (check_dst_dir): ... this new function, and...

5905 fail when copying files into lib/uniwidth/.
5906 * src/output.c (prepare_symbols): When writing yytname muscles, where
5907 symbol names will be encoded in C-string literals, tell quotearg to
5908 escape trigraphs. This used to be the default in gnulib.
5909 * tests/regression.at (Token definitions): Because of the change in
5910 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
5911 escapes trigraphs in symbol names. Thus, yytname no longer has
5912 trigraphs unnecessarily doubly escaped. Update test case output.
5913 Extend test case to be sure Bison's own error messages will no longer
5914 have trigraphs in symbol names unnecessarily escaped once.

7040 * src/lalr.c (state_lookahead_tokens_count): For code readability,
7041 move the check for disabled transitions to an aver since conflict
7042 resolution hasn't happened yet.
7043
7044 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
7045 labels a state as inconsistent just because it has error transitions.
7046 The original form of this check appeared in revision 1.1 of lalr.c,
7047 which was committed on 1991-12-21. Now (at least), changing the
7048 consistency label on such a state appears to have no useful effect in
7049 any of the places it is examined, which I enumerate below. The key
7050 point to understanding each item in this enumeration is that a state
7051 with an error transition is labelled consistent in the first place only
7052 if it has no rules, so the check cannot matter for states that have
7053 rules. (1) Labelling a state as inconsistent will cause set_conflicts
7054 to try to identify its conflicts, and a state must have *rules* to have
7055 conflicts. (2) Labelling a state as inconsistent will affect how
7056 action_row sets the default *rule* for the state. (3) Labelling a
7057 state as inconsistent will cause build_relations to add lookback edges
7058 to *rules* in that state.
7059 * src/state.h (struct state): Word the comment for member consistent
7060 more carefully.

7369 strcasecmp has "unspecified behavior" outside the POSIX locale,
7370 but it works fine in practice if at least one argument is ASCII,
7371 as is the case in Bison.

7569 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

7698 Instead of having skeletons declare all valid %define variables and

7700 and build these lists automatically. Thus Bison will now warn when a
7701 variable or qualifier is not used by the skeleton in the current
7702 invocation regardless of whether it might sometimes be used by that
7703 skeleton in other invocations. Also, move all %define value macros to
7704 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
7705 form, which is replaced by %code.
7706 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

7755 Check for unrecognized %define variables similar to checking for
7756 unrecognized %code qualifiers. Check for redefined %define variables.
7757 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
7758 generalizes...
7759 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
7760 (b4_check_percent_define_variables): New, also wraps it.
7761 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
7762 variables using b4_check_percent_define_variables.
7763 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
7764 all those exercised in the test suite and all those listed in the
7765 `Default values' section of c++.m4. Are there others?
7766 * data/push.c, data/yacc.c: Declare no valid %define variables.
7767 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
7768 similar to muscle_find, but it works even when the muscle stores a
7769 const value.
7770 (muscle_grow_used_name_list): New function for constructing the used
7771 name list muscles that b4_check_for_unrecognized_names requires.
7772 * src/parse-gram.y (prologue_declaration): Warn if a variable is
7773 %define'd more than once. Define the b4_used_percent_define_variables
7774 muscle with muscle_grow_used_name_list.

7783 * data/bison.m4 (b4_error_at): New, invoked by...
7784 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
7785 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
7786 @fatal_at(...@) directives.
7787 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
7788 qualifiers in b4_used_percent_code_qualifiers and to use
7789 b4_complain_at.
7790 * src/location.c, src/location.h (boundary_set_from_string): New global

7797 function.
7798 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
7799 (lineno): Rename to...
7800 (out_lineno): ... this so I don't misunderstand it again.
7801 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
7802 here; these newlines are in the input but not the output file.
7803 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
7804 (at_directive_perform): ... this new static function, and add handling
7805 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
7806 directives.

7824 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
7825 unreliable -- especially when they're hidden inside another macro.
7826 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
7827 data/c.m4: Remove m4_divert(-1).
7828 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
7829 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
7830 m4_divert_push(0) and m4_divert_pop(0).

7835 Provide warn, complain, and fatal function callbacks to the skeletons.
7836 This provides more flexibility than m4_fatal, improves the error

7838 starting at
7839 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
7840 * data/bison.m4 (b4_error): New, invoked by...
7841 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
7842 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
7843 directives. Because these M4 macros might be called when the current
7844 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
7845 the previous removal of uses of m4_divert, which caused trouble.
7846 (b4_check_percent_code_qualifiers): Use b4_complain instead of
7847 m4_fatal to report unrecognized %code qualifiers.
7848 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
7849 push parser requests.
7850 * data/glr.c: Use b4_complain instead of m4_fatal to report
7851 non-deterministic push parser requests.
7852 Update @output usage to @output(...@) form.

7854 report missing %defines. Update @output usage to @output(...@) form.
7855 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to

7860 obstack_for_string from flex-scanner.h.
7861 (YY_DECL): Use to declare skel_lex static.

7865 functions.

7867 at_directive_argv): New static globals.
7868 (INITIAL): Use fail_for_invalid_at.
7869 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
7870 recognize the start of a generalized `@directive(...@)' form and
7871 start...
7872 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
7873 directive args (using the new obstack_for_string), to decode the
7874 contained @ diagraphs, and to perform the directive. It recognizes
7875 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
7876 @output(...@).
7877 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
7878 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
7879 `@,'.
7880 (scan_skel): Initialize obstack_for_string on the first call.
7881 (skel_scanner_free): New function to free obstack_for_string.

7898 are replaced by b4_percent_code_provides and b4_percent_code_requires,
7899 which are skeleton-specific.
7900 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
7901 declare what %code qualifiers it supports and to complain if any other
7902 qualifiers were used in the grammar.

8006 field.
8007 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
8008 to ensure consistency.
8009 * src/scan-code.h (code_props): New structure.
8010 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
8011 function, macro, and const global variable for initializing a
8012 code_props with no code.
8013 (code_props_plain_init, code_props_symbol_action_init,
8014 code_props_rule_action_init, code_props_translate_code): The rest of
8015 the new code_props functional interface. Among other things, the init
8016 functions set the code_props kind field so that
8017 code_props_translate_code will know whether to behave like
8018 translate_symbol_action, translate_rule_action, or translate_code.
8019 These old translate functions must remain until all other modules are

8025 (code_lex): Make it static, add a code_props* argument, and remove the
8026 rule argument.
8027 (last_string): New static global similar to the one in scan-gram.l.
8028 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
8029 instead of rule.
8030 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
8031 code_props since Bison may one day use this information for destructors
8032 and printers.
8033 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
8034 (handle_action_dollar): Use symbol_list_n_get and set used flag
8035 directly since symbol_list_n_used_set is removed.
8036 (translate_action): Add a code_props* argument and remove the rule,
8037 action, and location arguments. Pass the code_props* on to code_lex.
8038 (translate_rule_action, translate_symbol_action, translate_code):
8039 Rewrite as wrappers around the new code_props interface.

8167 Enable push parsers to operate in impure mode. Thus, %push-parser no
8168 longer implies %pure-parser. The point of this change is to move
8169 towards being able to test the push parser code by running the entire
8170 test suite as if %push-parser had been declared.
8171 * data/push.c (yypush_parse): For impure mode, remove the
8172 yypushed_char, yypushed_val, and yypushed_loc arguments.
8173 Instead, declare these as local variables initialized to the global
8174 yychar, yylval, and yylloc.
8175 For the first yypush_parse invocation only, restore the initial values
8176 of these global variables when it's time to read a token since they
8177 have been overwritten.

8222 Rearrange initialization of the parser state variables so that the

8225 initialized (with b4_location_initial_line and
8226 b4_location_initial_column) upon calling yypush_parse. However, that
8227 initialization now overwrites the first token's location;
8228 %initial-action assigning @$ already did the same thing, and both bugs
8229 will be fixed in a later patch.

9292 composing the public interface of that table.

9333 Whether the default %destructor/%printer applies to a particular symbol
9334 isn't a question of whether the user *declares* that symbol (in %token,
9335 for example). It's a question of whether the user by any means
9336 *defines* the symbol at all (by simply using a char token, for
9337 example). $end is defined by Bison whereas any other token with token
9338 number 0 is defined by the user. The error token is always defined by
9339 Bison regardless of whether the user declares it with %token, but we
9340 may one day let the user define error as a nonterminal instead.
9341 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
9342 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
9343 the meaning of "user-defined".

9352 of '$', which a user symbol cannot have, and check for the error token.

9656 * NEWS: Instead of %union, you can define and use your own union type
9657 YYSTYPE if your grammar contains at least one <type> tag.
9658 Your YYSTYPE need not be a macro; it can be a typedef.
9659 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):

9667 Use 'union_seen' rather than 'typed' to determine whether
9668 %union has been seen, since grammars can now be typed without
9669 %union.
9670 (symbol_declaration, type.opt, symbol_def):

9679 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
9680 avoid new diagnostics generated by above changes.
9681 * tests/regression.at (YYSTYPE typedef): Add test to check
9682 for type tags without %union.

9685 int, since callers expect int. This may need to get revisited
9686 once we have proper integer overflow checking.

9689 object is now static.

9692 to pacify ./configure --enable-gcc-warnings.

9727 so they don't collide with user-defined macros.
9728 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
9729 this was never guaranteed, and now that we're using gnulib stdint,
9730 which defines int_fast16_t to long int, the problem is exposed.

9739 * bootstrap (gnulib_modules): Add stdint.
9740 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
9741 no longer copies it.
9742 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
9743 since stdint needs the former and wcwidth (which is now required
9744 by mbswidth) needs the latter.
9745 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
9746 work around a compatibility glitch between gettext 0.14.6 and
9747 Autoconf 2.60.
9748 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
9749 Do not check for uintptr_t, since new stdint module does the right
9750 thing.
9751 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.

9757 usual order for ../lib/*.h files.

9759 to gnulib changes.

9761 for ../lib/*.h files.
9762 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
9763 Define unconditionally, since we now assume the stdint module.
9764 * src/scan-skel.l: Include <dirname.h>.
9765 (BASE_QPUTS): Use last_component, not base_name.
9766 * src/system.h: Include <unlocked-io.h> in the usual order
9767 for ../lib/*.h files. Include <stdint.h> unconditionally,
9768 since we now use the stdint module.
9769 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
9770 HAVE_UINTPTR_T, since we now use the stdint module.
9771 (base_name): Remove decl, since files now include <dirname.h>
9772 to get the decl.

9850 grammar_rule_check yet since not all symbol declarations may have been
9851 parsed yet.
9852 (grammar_midrule_action): Likewise.
9853 Don't record whether the midrule's $$ has been used yet since actions
9854 haven't been translated yet.
9855 Record the midrule's parent rule and its RHS index within the parent
9856 rule.
9857 (grammar_current_rule_action_append): Don't translate the action yet
9858 since not all symbol declarations may have been parsed yet and, thus,
9859 warnings about types for $$, $n, @$, and @n can't be reported yet.
9860 (packgram): Translate the action and invoke grammar_rule_check now that
9861 all symbol declarations have been parsed.
9862 * src/scan-code.l (handle_action_dollar): Now that this is invoked
9863 after parsing the entire grammar file, the symbol list here in the case
9864 of a midrule is actually the midrule's empty RHS, so reference its
9865 parent rule's RHS where necessary.
9866 On the other hand, now that you can already know it's a midrule, you
9867 aren't forced to think $$ has the same type as its parent rule's $$.
9868 (handle_action_at): In the case of a midrule, reference the parent rule
9869 where necessary.
9870 * src/symlist.c (symbol_list_new): Initialize new midrule-related
9871 members.
9872 (symbol_list_length): Now that this is invoked after all rules have
9873 been parsed, a NULL symbol (rather than a NULL symbol list node)
9874 terminates a rule. symbol_list_print already does this correctly.
9875 * src/symlist.h (symbol_list.midrule_parent_rule,
9876 symbol_list.midrule_parent_rhs_index): New members so that midrules can
9877 remember their relationships with their parents.
9878 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
9879 fixed by the above patch.
9880 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
9881 implementing...
9882 (Unused values): ... this old test case and...
9883 (Unused values before symbol declarations): ... this new test case.
9884 This one is the same as `Unused values' except that all symbol

10824 During deterministic GLR operation, user actions should be able to
10825 influence the parse by changing yychar. To make this easier to fix and
10826 to make glr.c easier to evolve in general, don't maintain yytoken in

10854 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
10855 got from <http://bro-ids.org/download.html>. The bug is that
10856 when two actions appeared in succession, the second one was
10857 scanned before the first one was added to the grammar rule
10858 as a midrule action. Bison then output the incorrect warning
10859 "parse.y:905.17-906.36: warning: unused value: $3".

11145 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
11146 use during nondeterministic operation to track which stacks have
11147 actually needed the current lookahead.
11148 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
11149 Allocate, deallocate, resize, and otherwise shuffle space for
11150 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
11151 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
11152 appropriately during nondeterministic operation.
11153 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
11154 members to store the current lookahead to be used by the deferred
11155 user action.
11156 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
11157 from which the RHS is taken. Set the lookahead members of the new
11158 yySemanticOption according to the lookahead status for stack yyk.
11159 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
11160 yyaddDeferredAction.
11161 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
11162 members of yySemanticOption before invoking yyuserAction, and then set
11163 them back to their current values afterward.
11164 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
11165 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
11166 * tests/glr-regression.at: Remove `.' from the ends of recent test case
11167 titles for consistency.

11188 * data/glr.c (yyresolveValue): When merging semantic options, if at
11189 least one user action succeeds but a later one cuts the parse, then
11190 destroy the semantic value before returning rather than leaking it.
11191 (yyresolveStates): If a user action cuts the parse and thus
11192 yyresolveValue fails, ignore the (unset) semantic value rather than
11193 corrupting the yyGLRState, and empty the semantic options list since
11194 the user actions should have called all necessary destructors.
11195 Simplify code with YYCHK.
11196 * tests/glr-regression.at (Corrupted semantic options if user action
11197 cuts parse): New test case.
11198 (Undesirable destructors if user action cuts parse): New test case.
11199 Before applying any of this patch, this test case never actually failed
11200 for me... but only because the corrupted semantic options usually
11201 masked this bug.
11202 (Leaked merged semantic value if user action cuts parse): New test

12329 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
12330 that the byte '\0xff' is not printable in the C locale; it is,
12331 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
12332 not printable, so use '\0x81' to test.

12389 it's error-prone and "make maintainer-distcheck" rejects it.

12460 relevant strings from the obsolete translations. This code can be
12461 removed once the bison-runtime domain has been translated by each
12462 team.
12463
12464 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
12465 now that token names are already quoted.

12491 the 2005-04-17 change, which is now accomplished (mostly) via
12492 changes in the parsers as described above.

12498 Fix more problems reported by twlevo@xs4all.nl.
12499 * tests/cxx-type.at: Don't pipe output of ./types through sed to
12500 remove trailing spaces. This loses the exit status of ./types,
12501 and isn't needed since ./types shouldn't be emitting trailing
12502 spaces.
12503 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
12504 as the stack isn't valid in that case.

12517 overly-picky compilers that reject 'char *foo = "bar";'.
12518
12519 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
12520 to FILE * parameter, not to stderr. This fixes a typo introduced
12521 in the 2005-07-12 change.

12561 Rename yyoverflowab to yyexhaustedlab.
12562 When memory exhaustion occurs during syntax-error reporting,
12563 report it separately rather than in a single diagnostic; this

12581 get lost. See

12584 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
12585 Now auto-generated.
12586 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
12587 Fix typos in explanations of the runtime file.
12588 * bootstrap: Change gettext keyword from YYI18N to YY_.
12589 Use standard Makefile.in.in in runtime-po, since we'll arrange
12590 for backward-compatible bison-runtime.po files in a different way.
12591 * data/glr.c (YY_): New macro, from yacc.c.
12592 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
12593 Translate messages intended for users.
12594 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
12595 the wording in the other skeletons. We don't know that the memory
12596 is virtual.

12598 Use same method that yacc.c uses.
12599 Don't translate debugging messages.

12601 it doesn't work (yet), and requires C++ expertise to fix.
12602 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
12603 Move defn to a more logical place, to be consistent with other
12604 skeletons.
12605 Don't translate debugging messages.
12606 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
12607 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
12608 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
12609 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

12623 (yyStackOverflow): Just longjmp, but with value 2 so that caller

12625 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
12626 (yyparse): New local variable yyresult to record the result.

12628 struct.
12629 (yyDone): Remove label.
12630 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
12631 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
12632 if YYABORT is used).
12633 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
12634 yyparse status; put status > 1 into diagnostic.
12635 Check that status==2 works.
12636 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:

13357 it seems weird to return false on success. Returning true changes
13358 the conventions for yyparse.

13405 Remove uses of 'short int' and 'unsigned short int'. This raises
13406 some arbitrary limits. It uses more memory but nowadays that's
13407 not much of an issue.

13409 This change does not affect the generated parsers; that's a different
13410 task, as some users will want to conserve memory there.

13813 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
13814 whether the reducion was empty or not. This leaves room to
13815 improve the use of YYLLOC_DEFAULT in such a case.
13816 lalr1.cc is still experimental, so changing this is acceptable.
13817 And finally, there are probably not many users who changed the
13818 handling of locations in GLR, so changing is admissible too.

13964 Bison directive from the Bison file to the invocation of this
13965 macro, so that these directives are passed to
13966 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
13967 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
13968 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
13969 the extra Bison directives instead of the whole series.
13970 Change the grammar so that there are recoverable errors, and
13971 unrecoverable errors. Now we can have the parser give up before
13972 consuming the whole input. As a result we now can observe that
13973 the lookahead is freed when needed.
13974 Change the parser source to parse argv[1] instead of a hard coded
13975 string.
13976 Simplify yylex, and give a value and location to EOF.
13977 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
13978 passed directives already coded in the file.
13979 Add some tests to check the location of "error".
13980 For some tests, the C++ parser is correct, and not yacc.c.
13981 For other tests, they provide different, but unsatisfying, values,
13982 so keep the C++ value so that at least one parser is "correct"
13983 according to the test suite.
13984 (Actions after errors): Remove, this is subsumed by the
13985 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

14163 Spent a few hours checking out which prerequisite versions the
14164 current sources actually require. I went all the way back to
14165 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
14166 a seemingly endless set of combinations of versions more recent
14167 than that. The bottom line is that the current sources require
14168 fairly recent versions of the build tools, and it'll be some work
14169 to change this.

14686 location that is not defined. This results in garbage, and that

14820 Port to Forte Developer 7 C compiler.
14821 * data/glr.c (struct YYLTYPE): If locations are not being used,
14822 declare a single dummy member, as empty structs do not conform
14823 to the C standard.
14824 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
14825 the Forte Developer 7 C compiler complains that end-of-loop
14826 code is not reached.

14838
14839 * lib/bbitset.h: Do not include config.h; that's the includer's job.

14841 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
14842 Don't use 'index' in comments, as it's a builtin fn on some hosts.
14843 * lib/bitset_stats.c: Include gettext.h unconditionally, as
14844 per recent gettext manual's suggestion.
14845 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
14846 Use prototypes, not old-style definitions.
14847 * lib/lbitset.c (lbitset_unused_clear): Likewise.

14868 from libbitset.
14869
14870 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
14871 `How Can I Reset @code{yyparse}', since texinfo does not allow
14872 arbitrary @ in node names.
14873
14874 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
14875 shouldn't be needed according to the gettext 0.12.1 documentation
14876 but which seem to be needed anyway: codeset.m4 glibc21.m4

14898
14899 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
14900 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
14901 the tests right now.
14902 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
14903 yyerror are declared before use; C99 requires this.

14910 yyerrState.

14982 Fix a GLR parser bug I reported in February; see
161a71f3 14983 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
26ec81e0

14984 The problem was that GLR parsers did not conform to the C standard,
14985 because actions like { $1 = $2 + $3; } expanded to expressions
14986 that invoked YYFILL in separate subexpressions, and YYFILL assigned
14987 to a local variable. The C standard says that expressions
14988 like (var = f ()) + (var = f ()) have undefined behavior.
14989 Another problem was that GCC sometimes issues warnings that
14990 yyfill and its parameters are unused.
14991
14992 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
14993 as possibly unused.
14994 (yyfill): New function.
14995 (YYFILL): Use it.
14996 (yyuserAction): Change type of yynormal to bool, so that it matches
14997 the new yyfill signature. Mark it as possibly unused.
14998
14999
15000 Follow up on a bug I reported in February, where a Bison-generated
15001 parser can loop. Provide a test case and a fix for yacc.c. I
15002 don't have a fix for lalr1.cc or for glr.c, unfortunately.
15003 The original bug report is in:
161a71f3 15004 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
26ec81e0
PE
15005
15006 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
15007 macro's size was becoming unwieldy.
15008 (yyerrlab): Do not discard an empty lookahead symbol, as this
15009 might destroy garbage.
15010 (yyerrorlab): New label, with the old contents of YYERROR,
15011 plus the following change: pop the stack of rhs corresponding
15012 to the production that invoked YYERROR. That is how Yacc
15013 behaves, and POSIX requires this behavior.
15014 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
15015 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
15016 Define 'alarm' to do nothing if unistd.h is not available.
15017 Add a new rule "exp: '-' error;" to test the above change to
15018 data/yacc.c. Use 'alarm' to abort any test taking longer than
15019 10 seconds, as it's probably looping.
15020 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
15021 Also, the new yacc.c generates two fewer diagnostics for an
15022 existing test.

15026 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
15027 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.

15029 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM

15184 Declare to be of type suitable for the ninf value itself, not of
15185 type suitable for the corresponding table, since the latter might
15186 be unsigned but the ninf value might be negative. This fixes a

15191 invokes it. We shouldn't invoke it twice because it will attempt
15192 to put error.o in the archive twice. This fixes a glitch reported

15210 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
15211 Do not insert the expected token via unput, as this runs afoul
15212 of a POSIX-compatibility bug in flex 2.5.31.
15213 All uses changed to BEGIN the parent state,

15267 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
15268 cursor, instead of leaving it undefined. This fixes a bug

15275 <sys/resource.h> can be included, include sys/time.h and
15276 sys/times.h first, if available. This works around the SunOS
15277 4.1.4 porting bug reported by Bruce Becker in

15373 not loc->end, since loc->end might contain garbage and this leads
15374 to undefined behavior on some platforms.
15375 (id_loc, token_start): Use (IF_LINTed) initial values that do not
15376 depend on *loc, so that the reader doesn't give the the false
15377 impression that *loc is initialized.
15378 (<INITIAL>"%%"): Do not bother setting code_start, since its value
15379 does not survive the return.

15384 into yylex, as SC_EPILOGUE is activated *before* the corresponding
15385 yylex invocation. An alternative would be making it static, but
15386 then it starts with the second %%'s beginning, instead of its end.

15650 we don't need to worry about yyerrlab1 being reported as an
15651 "unused label" by non-GCC C compilers. The downside is that if
15652 locations are used then a couple of statements are duplicated each
15653 time YYERROR is invoked, but the upside is that the warnings
15654 should vanish.
15655 (yyerrlab1): Move code to YERROR.

15672 popped). This means that the initial elements will not be freed
15673 explicitly, as is the case in yacc.c; it is not a problem, as
15674 these elements have fake values.

15786 Renamed from conflict_report_yacc, removing the old
15787 'conflict_report'. Translate the entire conflict report at once,
15788 so that we don't assume that "," has the same interpretation in
15789 all languages.
15790 (conflicts_output): Use Yacc-style conflict report for each state,
15791 instead of our more-complicated style.

15793 the input file name when not emulating Yacc.

15811 * data/yacc.c (yyparse): New local var yylerrsp, to record the
15812 top of the location stack's error locations.
15813 (yyerrlab): Set it. When discarding a token, push its location
15814 onto yylerrsp so that we don't lose track of the error's end.
15815 (yyerrlab1): Now is only the target of YYERROR, so that we can
15816 properly record the location of the action that failed. For GCC
15817 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
15818 GCC warning about yyerrlab1 being unused if YYERROR is unused.
15819 (yyerrlab2): New label, which yyerrlab now falls through to.
15820 Compute the error's location by applying YYLLOC_DEFAULT to
15821 the locations of all the symbols that went into the error.
15822 * doc/bison.texinfo (Location Default Action): Mention that
15823 YYLLOC_DEFAULT is also invoked for syntax errors.
15824 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
15825 Error locations include the locations of all the tokens that were
15826 discarded, not just the last token.

15883 If the user does not define YYSTYPE as a macro, Bison now declares it
15884 using typedef instead of defining it as a macro. POSIX requires this.
15885 For consistency, YYLTYPE is also declared instead of defined.
15886
15887 %union directives can now have a tag before the `{', e.g., the
15888 directive `%union foo {...}' now generates the C code
15889 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
15890 The default union tag is `YYSTYPE', for compatibility with Solaris 9
15891 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
15892 instead of `yyltype'.
15893
15894 `yystype' and `yyltype' are now obsolescent macros instead of being
15895 typedefs or tags; they are no longer documented and will be
15896 withdrawn in a future release.
15897
15898 * data/glr.c (b4_location_type): Remove.
15899 (YYSTYPE): Renamed from yystype.
15900 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
15901 (struct YYLTYPE): Renamed from struct yyltype.
15902 (YYLTYPE): Renamed from yyltype.
15903 (yyltype, yystype): New (and obsolescent) macros,
15904 for backward compatibility.
15905 * data/yacc.c: Likewise.
15906
15907 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
15908 does not specify a union tag. This is for compatibility with
15909 Solaris 9 yacc.
15910
15911 * src/parse-gram.y (add_param): 2nd arg is now char * not char
15912 const *, since it is now modified by stripping surrounding { }.
15913 (current_braced_code): Remove.
15914 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
15915 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
15916 trailing " {...}". Now of type <chars>.
15917 (grammar_declaration): Adjust to bundled tokens.
15918 (code_content): Remove; stripping is now done by add_param.
15919 (print_token_value): Print contents of bundled tokens.
15920 (token_name): New function.
15921
15922 * src/reader.h (braced_code, current_braced_code): Remove.
15923 (token_name): New decl.
15924
15925 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
15926 token_type, not braced_code code_kind. All uses changed.
15927 (SC_PRE_CODE): New state, for scanning after a keyword that
15928 has (or usually has) an immediately-following braced code.
15929 (token_type): New local var, to keep track of which token type
15930 to return when scanning braced code.

15933 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
15934 instead of returning a token type immediately.
15935 (<INITIAL>"{"): Set token type.
15936 (<SC_BRACED_CODE>"}"): Use it.
15937 (handle_action_dollar, handle_action_at): Now returns bool
15938 indicating success. Fail if ! current_rule; this prevents a core dump.
15939 (handle_symbol_code_dollar, handle_symbol_code_at):
15940 Remove; merge body into caller.
15941 (handle_dollar, handle_at): Complain in invalid contexts.

16000 Remove unportable casts and storage allocation tricks.
16001 While we're at it, remove almost all casts, since they
16002 usually aren't needed and are a sign of trouble.
16003
16004 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
16005
16006 * src/derives.c (derives_compute): Do not subtract NTOKENS from
16007 the pointer DSET returned by malloc; this isn't portable.
16008 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
16009 Similarly for DERIVES.
16010 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
16011 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
16012 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
16013
16014 * src/derives.c (derives_compute): Do not bother invoking
16015 int_of_rule_number, since rule numbers are integers.
16016
16017 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
16018 rather than XMALLOC (char, N).
16019
16020 * src/files.c (filename_split): Rewrite to avoid cast.
16021
16022 * src/gram.h (symbol_number_as_item_number,
16023 item_number_as_symbol_number, rule_number_as_item_number,
16024 item_number_as_rule_number):
16025 Now inline functions rather than macros, to avoid casts.
16026 * src/state.h (state_number_as_int): Likewise.
16027 * src/tables.c (state_number_to_vector_number,
16028 symbol_number_to_vector_number): Likewise.

16030 * src/gram.h (int_of_rule_number): Remove; no longer used.
16031
16032 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
16033 since the resulting storage is always stored into.
16034
16035 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
16036 where it's needed.
16037
16038 * src/muscle_tab.c (muscle_m4_output):
16039 Now inline. Return bool, not int.
16040 * src/state.c (state_compare): Likewise.

16046 * src/muscle_tab.c (muscle_m4_output_processor):
16047 New function, to avoid casts.
16048 * src/state.c (state_comparator, stage_hasher): Likewise.

16050 symbol_check_alias_consistency_processor, symbol_pack_processor,
16051 symbol_translation_processor, hash_symbol_comparator,
16052 hash_symbol_hasher): Likewise.
16053 * src/uniqstr.c (uniqstr_print_processor): Likewise.
16054 * src/muscle_tab.c (muscles_m4_output):
16055 Use new functions instead of casting old functions unportably.
16056 * src/state.c (state_hash_new): Likewise.

16058 symbols_token_translations_init):

16060 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
16061
16062 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
16063 var instead of casting to long, to avoid casts.
16064 (prepare_states): Use MALLOC rather than alloca, so that we don't
16065 have to worry about alloca.
16066 * src/state.c (state_hash_lookup): Likewise.
16067
16068 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
16069 local var instead of casting to unsigned char, to avoid casts.
16070
16071 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
16072 STATE_ALLOC): Remove.
16073 (transitions_new, errs_new, reductions_new, state_new): Use malloc
16074 rather than calloc, and use offsetof to avoid allocating slightly
16075 too much storage.
16076 (state_new): Initialize all members.
16077
16078 * src/state.c (state_hash): Use unsigned accumulator, not signed.
16079
16080 * src/symtab.c (symbol_free): Remove; unused.
16081 (symbol_get): Remove cast in lhs of assignment.
16082 (symbols_do): Now static. Accept generic arguments, not
16083 hashing-related ones.
16084
16085 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
16086 (symbol_processor): Remove.
16087 (symbols_do): Remove decl; now static.

16091 (<inttypes.>, <stdint.h>): Include if available.
16092 (uintptr_t): New type, if system lacks it.
16093 (CALLOC, MALLOC, REALLOC): New macros.
16094 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
16095 new macros.
16096
16097 * src/tables.c (table_size): Now int, to pacify GCC.
16098 (table_grow, table_ninf_remap): Use signed table size.
16099 (save_row): Don't bother initializing locals when not needed.
16100 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
16101 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
16102
16103 * src/vcg.h: Correct misspellings.
16104
16105 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.

16112 Change identifier spellings to avoid collisions with names
16113 that are reserved by POSIX.
16114
16115 Don't use names ending in _t, since POSIX reserves them.
16116 For consistency, remove _e and _s endings -- they're weren't
16117 needed to remove ambiguity. All uses changed.
16118 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
16119 turn was just renamed from struniq_t.

16277 Add support for rules that do not have trailing semicolons, as
16278 POSIX requires. Improve the quality of locations in Bison
16279 diagnostics.
26b4a969 16280
e19c4e5d
PE
16281 * src/location.c: Include <quotearg.h>.
16282 (empty_location): Now const.
16283 (location_print): New function. Follow the recommendation of the
16284 GNU Coding Standards for locations that span file boundaries.
16285 * src/location.h: Do not include <quotearg.h>; no longer needed.
16286 (boundary): New type.
16287 (location_t): Use it. This allows locations to span file boundaries.
16288 All member uses changed: file -> start.file or end.file (as needed),
16289 first_line -> start.line, first_column -> start.column,
16290 last_line -> end.line, last_column -> end.column.
16291 (equal_boundaries): New function.
16292 (LOCATION_RESET, LOCATION_STEP): Remove.
16293 (LOCATION_PRINT): Remove. All callers changed to use location_print.
16294 (empty_location): Now const.
16295 (location_print): New decl.
16296 * src/parse-gram.y (lloc_default): New function, which handles
16297 empty locations more accurately.
16298 (YYLLOC_DEFAULT): Use it.
16299 (%token COLON): Remove.
16300 (%token ID_COLON): New token.
26b4a969 16301 (rules): Use it.
e19c4e5d
PE
16302 (declarations, rules): Remove trailing semicolon.
16303 (declaration, rules_or_grammar_declaration):
16304 Allow empty (";") declaration.
16305 (symbol_def): Remove empty actions; no longer needed.
16306 (rules_or_grammar_declaration): Remove trailing semicolon.
16307 (semi_colon.opt): Remove.
16308 * src/reader.h: Include location.h.
16309 (scanner_cursor): New decl.
16310 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
16311 rolling our own.
16312 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
16313 of *loc.
16314 (STEP): Remove. No longer needed, now that adjust_location does
16315 the work. All uses removed.
16316 (scanner_cursor): New var.
16317 (adjust_location): Renamed from extend_location. It now sets
16318 *loc and adjusts the scanner cursor. All uses changed.
16319 Don't bother testing for CR.
16320 (handle_syncline): Remove location arg; now updates scanner cursor.
16321 All callers changed.
16322 (unexpected_end_of_file): Now accepts start boundary of token or
16323 comment, not location. All callers changed. Update scanner cursor,
16324 not the location.
16325 (SC_AFTER_IDENTIFIER): New state.
16326 (context_state): Renamed from c_context. All uses changed.
16327 (id_loc, code_start, token_start): New local vars.
16328 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
16329 processing of Yacc white space and equivalents here.
16330 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
16331 instead of returning ID immediately, since we need to search for
16332 a subsequent colon.
16333 (<INITIAL>"'", "\""): Save token_start.
16334 (<INITIAL>"%{", "{", "%%"): Save code_start.
16335 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
16336 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
16337 BEGIN context_state at end, not INITIAL.
16338 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
16339 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
16340 Return correct token start.
16341 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
16342 the start of a character, string or multiline comment is found.
16343 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
16344 Reduction): Adjust reported locations to match the more-precise
16345 results now expected.
16346 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
16347 * tests/reduce.at (Useless Rules, Reduced Automaton,
16348 Underivable Rules): Likewise.
16349 * tests/regression.at (Invalid inputs): No longer `expecting ";"
16350 or "|"' now that so many other tokens are allowed by the new grammar.
16351
16352 * src/complain.h (current_file): Remove duplicate decl;
16353 current_file is now owned by files.h.
16354 * src/complain.c, src/scan-gram.l: Include files.h.

PE
16358 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
16359 promotes to int; it might be unsigned int.
16360 * data/yacc.c (yy_reduce_print): Likewise.
16361
16362 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
16363 be #defined in the prologue, not in the Bison declarations.
16364 This fixes Debian Bug 102878, reported by Shaul Karl.

16369 * lib/strtoul.c: New file, from gnulib.
16370 This fixes a porting bug reported by Peter Klein in
161a71f3 16371 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.

b64755e3
PE
16375 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
16376 and put only a forward declaration in the prologue. This is for
16377 consistency with the other scanner helper functions.
16378
6ba55592
PE
16379 Type clashes now generate warnings, not errors, since it
16380 appears that POSIX may allow some grammars with type clashes.
16381 * src/reader.c (grammar_current_rule_check): Warn about
16382 type clashes instead of complaining.
16383 * tests/input.at (Type Clashes): Expect warnings, not complaints.
16384
6e746484
PE
16385 Add Yacc library, since POSIX requires it.
16386 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
16387 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
16388 * lib/main.c, lib/yyerror.c: New files.
16389
16390 gram_error can be static; it need not be extern.
16391 * src/reader.h (gram_error): Remove decl.
16392 * src/parse-gram.y (gram_error): Now static. Add static decl.
16393 (print_token_value): Omit parameter names from forward decl,
16394 for consistency.

16397
6e746484
PE
16398 * doc/bison.texinfo: Emphasize that yylex and yyerror must
16399 be declared before being used. E.g., one should typically
16400 declare them in the prologue. Use GNU coding style in examples.
16401 Put "const" consistently after the type it modifies. Mention
16402 that C99 supports "inline". Mention that yyerror traditionally
16403 returns "int".
16404
88510f9c
PE
16405 %parse-param and %lex-param now take just one argument, the
16406 declaration; the argument name is deduced from the declaration.
16407
16408 * doc/bison.texinfo (Parser Function, Pure Calling, Error
16409 Reporting, Table of Symbols): Document this.
16410 * src/parse-gram.y (add_param): New function.
16411 (COMMA): Remove.
16412 (declaration): Implement new rule for %parse-param and %lex-param.
16413 * src/scan-gram.l: "," now elicits a warning, rather than being
16414 a token; this is more compatible with byacc.
16415 * tests/calc.at (Simple LALR Calculator): Adopt new convention.

16419 Rename identifiers to avoid real and potential collisions.
16420
16421 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
16422 to avoid collision with lex macro described by Bruce Lilly in
161a71f3 16423 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.

16427 All uses changed.
16428 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
16429 The name "yycontrol" violates the name space rules, and this stuff
16430 wasn't being used anyway.
16431 (input): Remove action; this stuff wasn't being used.
16432 (gram_error): Rename local variable yylloc -> loc.
16433 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
16434 (YY_DECL): Don't use "yy" at start of local variables.
16435 All uses changed, e.g., yylloc -> loc.

16437 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
16438 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
16439 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.

16446 Version 1.75c.
16447
16448 * tests/actions.at (Actions after errors): Use an output format
16449 more similar to that of the Printers and Destructors test.
16450 Test the position of the ';' token too.
16451 (Printers and Destructors): Likewise.
16452 (Printers and Destructors: %glr-parser): Remove for now, to avoid
16453 unnecessarily alarming people when the test fails.
16454
16455 * data/yacc.c (yyerrlab1): Move this label down, so that the
16456 parser does not discard the lookahead token if the user code
16457 invokes YYERROR. This change is required for POSIX conformance.
16458
16459 * lib/error.c: Sync with gnulib.

16473 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
16474 should use `if (! x) abort ();' rather than `assert (x);', and
16475 anyway it's one less thing to worry about configuring.
16476
16477 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
16478 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,

16519 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
16520 This fixes the regression with Sun ONE Studio 7 cc that I reported in

16531 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
16532 to "SyntaxError" for consistency with my 2002-11-15 change.
16533
16534 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
16535 not define to {}, since this breaks the common use of `YYDPRINTF
16536 ((...));' if a single statement is desired (e.g. before `else').
16537 Work around GCC warnings by surrounding corresponding calls with
16538 {} if needed.
16539 (yyhasResolvedValue): Remove unused function.
16540 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
16541 loop body.

16889 Use new @ escapes consistently. Represent brackets with @{ and @}
16890 rather than @<:@ and @:>@, since this works a bit better with dumb

16892 an escape. Use @oline@ and @ofile@ rather than __oline__ and
16893 __ofile__, to avoid unexpected expansions. Similarly, use @output
16894 rather than #output.
16895
16896 * data/c.m4 (b4_copyright): Omit file name from comment, since
16897 the file name could contain "*/".

17303

17678 Let nondeterministic skeletons be usable with deterministic
17679 tables.
17680
17681 With the patch, GAWK compiled by GCC without -O2 passes its test
17682 suite using a GLR parser driven by LALR tables. It fails with -O2
17683 because `struct stat' gives two different answers on my machine:
17684 88 (definition of an auto var) and later 96 (memset on this var).
17685 Hence the stack is badly corrumpted. The headers inclusion is to
17686 blame: if I move the awk.h inclusion before GLR's system header
17687 inclusion, the two struct stat have the same size.

17745 Use it to keep track of the rule length in the scanner, since
17746 we can't expect the parser to be in lock-step sync with the scanner.

17802 * lib/lbitset.c: Likewise.
17803
17804 * lib/abitset.c (abitset_bytes): Return a size that is aligned
17805 properly for vectors of objects. Do not assume that adding a
17806 header size to a multiple of a word size yields a value that is
17807 properly aligned for the whole union.
17808 * lib/bitsetv.c (bitsetv_alloc): Likewise.
17809
17810 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
17811 unique names for structures.
17812 * lib/ebitset.c (ebitset_bytes): Likewise.
17813 * lib/lbitset.c (lbitset_bytes): Likewise.
17814
17815 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
17816 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
17817 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

17821 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
17822 to improve the type-checking that GCC can do.
17823 * lib/bitset.c (bitset_op4_cmp): Likewise.

17825 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

17835 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
17836 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,

17844 All instances of parameters of type enum bitset_opts are now of
17845 type enum_bitset_opts, to conform to the C Standard, and similarly
17846 for enum_bitset_type.
17847 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
17848 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
17849
17850 Do not use "struct bitset_struct" to mean different things in
17851 different modules. Not only is this confusing, it violates
17852 the C Standard, which requires that structure types in different
17853 modules must be compatible if one is to be passed to the other.
17854 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
17855 All instances of "struct bitset_struct *" replaced with "bitset".
17856 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
17857 (union bitset_union, struct abitset_struct, struct ebitset_struct,
17858 struct lbitset_struct, struct bitset_stats_struct): New types.
17859 All uses of struct bitset_struct changed to union bitset_union,
17860 etc.
ba0fe3c7 17861 * lib/abitset.c (struct abitset_struct, abitset,
f28a0f2d

17862 struct bitset_struct): Remove.

17866 bitset_struct): Remove.

17868 Likewise.
17869
17870 Do not call a function of type T using a call that assumes the
17871 function is of a different type U. Standard C requires that a
17872 function must be called with a type that is compatible with its
17873 definition.
17874 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17875 New decls.
17876 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):

17882 decls.
17883 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
17884 (ebitset_vtable): Use them.

17893 GCC warning.

17916 the portable Standard C character set.

17918 The GNU coding standard says CFLAGS and YFLAGS are reserved
17919 for the installer to set.

18245 manual recommends.
18246 Similarly, use src/scan-gram.l instead of src/scan-gram.c.

18249 (strerror): Use same pattern as ../lib/error.c.
18250
18251 * src/files.c, src/files.h (compute_header_macro): Remove; unused.

18254

18256 to void, to avoid a GCC warning when --disable-nls is in effect.
18257

18259 to minimize the number of warnings from xgettext.
18260 (handle_action_dollar, handle_action_at): Don't use isdigit,
18261 as it mishandles negative chars and it may not work as expected
18262 outside the C locale.
18263
18264 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
18265 this is a GCC extension and is not portable to other compilers.
18266
18267 * src/system.h (alloca): Use same pattern as ../lib/error.c.
18268 Do not include <ctype.h>; no longer needed.
18269 Do not include <malloc.h>; no longer needed (and generates
18270 warnings on OpenBSD 3.0).
18271
18272 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
18273 it's not portable.
18274
18275 * tests/regression.at: Do not use 'cc -c input.c -o input';
18276 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
18277
18278 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
18279 exit status as failure, not just exit status 1. Sun C exits
18280 with status 2 sometimes.
18281
18282 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
18283 Use it for the two large tests.

20877 that.
20878 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
20879 file will be used.
20880 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.

20882 usable in M4, rename the muscles using `-' to `_'.

20887 processes the output of m4: `__oline__' and `#output'.

21461 these states are automatically computed from the initial state.
21462 (generate_states): Adjust.
21463 * src/print.c: When reporting a rule number to the user, substract

21470 0: `$axiom: START-SYMBOL $'.

21472 number of the states has changed (the final state is no longer
21473 necessarily the last), catch up.

21480 instead of the 0-sentinel.

21499 (packsymbols): No longer hack `tags' to insert `$' by hand.
21500 Be sure to preserve the value of the eoftoken.
21501 (reader): Make sure eoftoken is defined.
21502 Initialize nsyms to 0: now eoftoken is created just like the others.
21503 * src/print.c (print_grammar): Don't special case the eof token.
21504 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
21505 lie anyway, albeit pleasant.
21506 * tests/calc.at: Exercise error messages with eoftoken.
21507 Change the grammar so that empty input is invalid.

22511 three stacks, instead of allocating three blocks; this typically is
22512 faster and reduces fragmentation.

22514 Do not limit the number of items in the stack to a value that fits

24780 Test also `--verbose', `--defines' and `--name-prefix'. Testing
24781 the latter demonstrates a flaw in the handling of non debugging
24782 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
24783 was used in order to simplify:
24784
24785 #if YYDEBUG
24786 if (yydebug)
24787 {
24788 ...
24789 }
24790 #endif
24791
24792 into
24793
24794 if (yydebug)
24795 {
24796 ...
24797 }
24798
24799 unfortunately this leads to a CPP conflict when
24800 `--name-prefix=foo' is used since it produces `#define yydebug
24801 foodebug'.

24851 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
24852 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
24853 difficult and introduced a lot of core dump. It turns out that
24854 Bison used an implementation of `xmalloc' based on `calloc', and
24855 at various places it does depend upon the initialization to 0. I
24856 have not tried to isolate the pertinent places, and all the former
24857 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
24858 someone should address this issue.

25228 Change the handling of @s so that they behave exactly like $s.
25229 There is now a pseudo variable @$ (readble and writable), location
25230 of the lhs of the rule (by default ranging from the location of
25231 the first symbol of the rhs, to the location of the last symbol,
25232 or, if the rhs is empty, YYLLOC).
25233
25234 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
25235 yyval.
25236 (yyparse): When providing a default semantic action, provide a
25237 default location action.
25238 (after the $): No longer change `*YYLSP', just stack YYLOC the
25239 same way you stack YYVAL.
25240 * src/reader.c (read_declarations): Use warns.
25241 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
25242 (copy_action, case '@'): Likewise.

25267 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
25268 One `#if YYDEBUG' remains, since it uses variables which are
25269 defined only if `YYDEBUG != 0'.

25995 way to specify the flags -n, -l, and -r. Also added hooks for
