6 number.
7 Call yytranslate_.
8 * data/variant.hh (b4_symbol_constructor_define_): Therefore,
9 don't call yytranslate_ here.

46 lalr1.cc: syntax_error as exceptions.
47 It is common to use sort of factories in the user actions. These
48 factories may check some "syntactic" constraints that are not
49 enforced by the grammar itself. This is possible using YYERROR
50 within the action itself. Provide the user with a means to throw
51 a syntax_error exception.

256 More fixes related to last two patches.
257 * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
258 comments: zero indicates syntax error not default action.
259 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
260 defined.
261 * data/glr.c (yyis_pact_ninf): Rename to...
262 (yypact_value_is_default): ... this.
263 (yyisDefaultedState): Update for rename.
264 (yyis_table_ninf): Rename to...
265 (yytable_value_is_error): ... this, and check for value zero
266 besides just YYTABLE_NINF.
267 (yygetLRActions): Check for default value from yypact. It
268 appears that this check is always performed before this function
269 is invoked, and so adding the check here is probably redundant.
270 However, the code may evolve after this subtlety is forgotten.
271 Also, update for rename to yytable_value_is_error. Because that
272 macro now checks for zero, a different but equivalent branch of
273 the if-then-else here is evaluated.
274 (yyreportSyntaxError): Update for rename to
275 yytable_value_is_error. The zero condition was mishandled
276 before.
277 (yyrecoverSyntaxError): Update for renames. No behavioral
278 changes.
279 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
280 New function.
281 (yy_table_value_is_error_): New function.
282 (parse): Use new functions where possible. No behavioral
283 changes.
284 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
285 The zero condition was mishandled before.

293 (yyparse): Update for renames. No behavioral changes.
294 * src/tables.h: Improve comments about yypact, yytable, etc.

296 error not default action.

455 build: lower gettext requirements.
456
457 Bison was uselessly requiring the formatstring macros from
458 gettext, which resulted in mo files not being installed on systems
459 that perfectly supported Bison mo files. Lower the requirement.

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

544 build: fix paths.
545 When using $(top_builddir) inconsistently, Make (including GNU
546 Make) is sometimes confused. As a result it may want to build
547 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
548 file, different names) concurrently, which, amusingly enough,
549 might end with:

2301 There are two issues to handle: first scanning nested angle

2305 Another issue is to address idiosyncracies of C++: do not glue two
2306 closing angle brackets together (otherwise it's operator>>), and
2307 avoid sticking blindly a TYPE to the opening <, as it can result
2308 in '<:' which is a digraph for '['.

2568 To reach good performances these functions should be inlined (yet
2569 this is to measure precisely). To this end they must be available
2570 to the caller.

2620 Finer input type for yytranslate.
2621 This patch is debatable: the tradition expects yylex to return an int
2622 which happens to correspond to token_number (which is an enum). This
2623 allows for instance to return characters (such as '*' etc.). But this
2624 goes against the stronger typing I am trying to have with the new
2625 lex interface which return a symbol_type. So in this case, feed
2626 yytranslate_ with a token_type.
2df9ec37 2627
4654b0c0

2803 Introduce make_symbol.
b06df3c2
AD
2804 make_symbol provides a means to construct a full symbol (kind,
2805 value, location) in a single shot. It is meant to be a Symbol
2806 constructor, parameterized by the symbol kind so that overloading
2807 would prevent incorrect kind/value pairs. Unfortunately
2808 parameterized constructors do not work well in C++ (unless the
2809 parameter also appears as an argument, which is not acceptable),
2810 hence the use of a function instead of a constructor.

3025 Change the handling of the symbols in the skeletons.
3026 Before we were using tables which lines were the symbols and which
3027 columns were things like number, tag, type-name etc. It is was
3028 difficult to extend: each time a column was added, all the numbers had
3029 to be updated (you asked for colon $2, not for "tag"). Also, it was
3030 hard to filter these tables when only a subset of the symbols (say the
3031 tokens, or the nterms, or the tokens that have and external number
3032 *and* a type-name) was of interest.
de62edee 3033
d69c9694
AD
3034 Now instead of monolithic tables, we define one macro per cell. For
3035 instance "b4_symbol(0, tag)" is a macro name which contents is
3036 self-decriptive. The macro "b4_symbol" provides easier access to
3037 these cells.

3360 Unfortunately this uncovered a bug in the C++ parser itself: the
3361 lookahead value was not destroyed between two calls to yylex. For
3362 instance if the previous lookahead was a std::string, and then an int,
3363 then the value of the std::string was correctly taken (i.e., the
3364 lookahead was now an empty string), but std::string structure itself
3365 was not reclaimed.
de62edee 3366

3367 This is now done in variant::build(other&) (which is used to take the
3368 value of the lookahead): other is not only stolen from its value, it
3369 is also destroyed. This incurs a new performance penalty of a few

3651 Fuse the three stacks into a single one.
de62edee 3652
b06df3c2
AD
3653 In order to make it easy to perform benchmarks to ensure that
3654 there are no performance loss, lalr1.cc is forked into
3655 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
3656 lalr1.cc.
3657
3658 Meanwhile, to make sure that lalr1-fusion.cc is correctly
3659 exercized by the test suite, the user must install a symbolic link
3660 from lalr1.cc to it.
de62edee 3661
b06df3c2

3662 Instead of having three stacks (state, value, location), use a
3663 stack of triples. This considerably simplifies the code (and it
3664 will be easier not to require locations as currently does the C++
3665 parser), and also gives a 10% speedup according to
3666 etc/bench (probably mainly since memory allocation is done once
3667 instead of three times).
de62edee 3668
0e0ed236
AD
3669 Another motivation is to make it easier to destruct properly
3670 semantic values: now that they are bound to their state (hence
3671 symbol type) it will be easier to call the appropriate destructor.

3718 Use variants to support objects as semantic values.
b06df3c2
AD
3719 This patch was inspired by work by Michiel De Wilde. But he used
3720 Boost variants which (i) requires Boost on the user side, (ii) is
3721 slow, and (iii) has useless overhead (the parser knows the type of
3722 the semantic value there is no reason to duplicate this
3723 information as Boost.Variants do).
3724
3725 This implementation reserves a buffer large enough to store the
3726 largest objects. yy::variant implements this buffer. It was
3727 implemented with Quentin Hocquet.

4282 Update to the current gnulib CVS repository, and fix trigraph handling

4284 * bootstrap: Update gnulib CVS repository URL.
4285 (symlink_to_dir): Encapsulate the code that guarantees the destination
4286 directory exists into...
4287 (check_dst_dir): ... this new function, and...
4288 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
4289 fail when copying files into lib/uniwidth/.
4290 * src/output.c (prepare_symbols): When writing yytname muscles, where
4291 symbol names will be encoded in C-string literals, tell quotearg to
4292 escape trigraphs. This used to be the default in gnulib.
4293 * tests/regression.at (Token definitions): Because of the change in
4294 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
4295 escapes trigraphs in symbol names. Thus, yytname no longer has
4296 trigraphs unnecessarily doubly escaped. Update test case output.
4297 Extend test case to be sure Bison's own error messages will no longer
4298 have trigraphs in symbol names unnecessarily escaped once.

5019 Fix some error-reporting macro bugs.
5020 * data/bison.m4 (b4_cat): New.
5021 (b4_error, b4_error_at): Use b4_cat to send error directives directly
5022 to stdout so they don't become arguments to other macros. Update
5023 comments and add examples.
5024 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
5025 add examples.
5026 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
5027 after printing the error directive so that M4 doesn't report subsequent
5028 problems that are induced by this problem.
5029 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
5030 instead of just in them. Recognize @\n in both places. Both expand to
5031 the empty string. Needed by b4_cat.
5032 * tests/skeletons.at (Complaining during macro argument expansion):
5033 New test case.
5034 (Fatal errors make M4 exit immediately): New test case.

5075 parsing requests here...

5077 b4_use_push_pull_flag or the %define variable push_pull is set. This
5078 will go away when we mv push.c yacc.c.
5079 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that

5424 * src/lalr.c (state_lookahead_tokens_count): For code readability,
5425 move the check for disabled transitions to an aver since conflict
5426 resolution hasn't happened yet.
5427
5428 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
5429 labels a state as inconsistent just because it has error transitions.
5430 The original form of this check appeared in revision 1.1 of lalr.c,
5431 which was committed on 1991-12-21. Now (at least), changing the
5432 consistency label on such a state appears to have no useful effect in
5433 any of the places it is examined, which I enumerate below. The key
5434 point to understanding each item in this enumeration is that a state
5435 with an error transition is labelled consistent in the first place only
5436 if it has no rules, so the check cannot matter for states that have
5437 rules. (1) Labelling a state as inconsistent will cause set_conflicts
5438 to try to identify its conflicts, and a state must have *rules* to have
5439 conflicts. (2) Labelling a state as inconsistent will affect how
5440 action_row sets the default *rule* for the state. (3) Labelling a
5441 state as inconsistent will cause build_relations to add lookback edges
5442 to *rules* in that state.
5443 * src/state.h (struct state): Word the comment for member consistent
5444 more carefully.

5953 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

5958 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5959 expect any unqualified %code blocks to be stored in a macro named
5960 `b4_percent_code_unqualified'.
5961 Use m4_indir so that %define variable names and %code qualifiers can
5962 contain `.', which is allowed by the grammar parser.

6082 Instead of having skeletons declare all valid %define variables and

6084 and build these lists automatically. Thus Bison will now warn when a
6085 variable or qualifier is not used by the skeleton in the current
6086 invocation regardless of whether it might sometimes be used by that
6087 skeleton in other invocations. Also, move all %define value macros to
6088 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
6089 form, which is replaced by %code.
6090 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

6165 Provide warn_at, complain_at, and fatal_at function callbacks to the

6167 * data/bison.m4 (b4_error_at): New, invoked by...
6168 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
6169 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
6170 @fatal_at(...@) directives.
6171 (b4_check_percent_code_qualifiers): Rewrite to expect locations for

6181 function.
6182 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
6183 (lineno): Rename to...
6184 (out_lineno): ... this so I don't misunderstand it again.
6185 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
6186 here; these newlines are in the input but not the output file.
6187 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
6188 (at_directive_perform): ... this new static function, and add handling
6189 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
6190 directives.

6201 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
6202 documentation and add examples.

6208 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
6209 unreliable -- especially when they're hidden inside another macro.
6210 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
6211 data/c.m4: Remove m4_divert(-1).
6212 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
6213 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
6214 m4_divert_push(0) and m4_divert_pop(0).
279cabb6 6215 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and

6217 pushed and popped by m4sugar, should be first on the stack.
6218
6219 Provide warn, complain, and fatal function callbacks to the skeletons.
6220 This provides more flexibility than m4_fatal, improves the error
6221 message format, and captures messages for translation. Discussed
6222 starting at
6223 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
6224 * data/bison.m4 (b4_error): New, invoked by...
6225 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
6226 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
6227 directives. Because these M4 macros might be called when the current
6228 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
6229 the previous removal of uses of m4_divert, which caused trouble.
6230 (b4_check_percent_code_qualifiers): Use b4_complain instead of
6231 m4_fatal to report unrecognized %code qualifiers.
6232 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
6233 push parser requests.
6234 * data/glr.c: Use b4_complain instead of m4_fatal to report
6235 non-deterministic push parser requests.
6236 Update @output usage to @output(...@) form.
6237 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
6238 report missing %defines. Update @output usage to @output(...@) form.
6239 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
6240 @output(...@) form.

6242 * src/scan-skel.h (skel_scanner_free): Prototype new function.
6243 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
6244 obstack_for_string from flex-scanner.h.
6245 (YY_DECL): Use to declare skel_lex static.
6246 (decode_at_digraphs): Remove; now handled in the new
6247 SC_AT_DIRECTIVE_ARG start condition.
6248 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
6249 functions.
6250 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
6251 at_directive_argv): New static globals.
6252 (INITIAL): Use fail_for_invalid_at.
6253 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
6254 recognize the start of a generalized `@directive(...@)' form and
6255 start...
6256 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
6257 directive args (using the new obstack_for_string), to decode the
6258 contained @ diagraphs, and to perform the directive. It recognizes
6259 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
6260 @output(...@).
6261 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
6262 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
6263 `@,'.
6264 (scan_skel): Initialize obstack_for_string on the first call.
6265 (skel_scanner_free): New function to free obstack_for_string.

6282 are replaced by b4_percent_code_provides and b4_percent_code_requires,
6283 which are skeleton-specific.
6284 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
6285 declare what %code qualifiers it supports and to complain if any other
6286 qualifiers were used in the grammar.
6287 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
6288 and b4_user_code([b4_percent_code_provides]) in place of
6289 b4_user_requires and b4_user_provides.

6299 which defines muscles of the form b4_percent_code_QUALIFIER and the
6300 b4_used_percent_code_qualifiers muscle.

6312 printer members to code_props.

6318 types in place of char const * and location.
6319 (symbol_destructor_location_get, symbol_printer_location_get): Remove
6320 since the locations are now contained in the return of
6321 symbol_destructor_get and symbol_printer_get.
6322 * src/output.c (symbol_destructors_output, symbol_printers_output):
6323 Replace with...
6324 (symbol_code_props_output): ... this to eliminate duplicate code.
6325 (output_skeleton): Update to use symbol_code_props_output.
6326 * src/reader.c (symbol_should_be_used): Update use of

6386 Discussed starting at
6387 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
6388 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
6389 consistently initialize const structs that have an empty location
6390 field.
6391 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
6392 to ensure consistency.
6393 * src/scan-code.h (code_props): New structure.
6394 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
6395 function, macro, and const global variable for initializing a
6396 code_props with no code.
6397 (code_props_plain_init, code_props_symbol_action_init,
6398 code_props_rule_action_init, code_props_translate_code): The rest of
6399 the new code_props functional interface. Among other things, the init
6400 functions set the code_props kind field so that
6401 code_props_translate_code will know whether to behave like
6402 translate_symbol_action, translate_rule_action, or translate_code.
6403 These old translate functions must remain until all other modules are
6404 updated to use the new code_props interface.
6405 (code_scanner_last_string_free): New function similar to
6406 gram_scanner_last_string_free.
6407 (code_scanner_free): Add documentation.
6408 * src/scan-code.l: Implement the new interface.
6409 (code_lex): Make it static, add a code_props* argument, and remove the
6410 rule argument.
6411 (last_string): New static global similar to the one in scan-gram.l.
6412 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
6413 instead of rule.
6414 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
6415 code_props since Bison may one day use this information for destructors
6416 and printers.
6417 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
6418 (handle_action_dollar): Use symbol_list_n_get and set used flag
6419 directly since symbol_list_n_used_set is removed.
6420 (translate_action): Add a code_props* argument and remove the rule,
6421 action, and location arguments. Pass the code_props* on to code_lex.
6422 (translate_rule_action, translate_symbol_action, translate_code):
6423 Rewrite as wrappers around the new code_props interface.

6452 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to

6551 Enable push parsers to operate in impure mode. Thus, %push-parser no
6552 longer implies %pure-parser. The point of this change is to move
6553 towards being able to test the push parser code by running the entire
6554 test suite as if %push-parser had been declared.
6555 * data/push.c (yypush_parse): For impure mode, remove the
6556 yypushed_char, yypushed_val, and yypushed_loc arguments.
6557 Instead, declare these as local variables initialized to the global
6558 yychar, yylval, and yylloc.
6559 For the first yypush_parse invocation only, restore the initial values
6560 of these global variables when it's time to read a token since they
6561 have been overwritten.
6562 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
6563 %push-parser.
6564 * tests/calc.at (Simple LALR(1) Calculator): Always declare

6606 Rearrange initialization of the parser state variables so that the
6607 skeleton doesn't have to have a copy for pull mode and another for push
6608 mode. This patch also fixes at least a bug such that yylloc was not
6609 initialized (with b4_location_initial_line and
6610 b4_location_initial_column) upon calling yypush_parse. However, that
6611 initialization now overwrites the first token's location;
6612 %initial-action assigning @$ already did the same thing, and both bugs
6613 will be fixed in a later patch.

6623 "Starting parse" diagnostic for invocations after the first.
6624 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
6625 yypush_parse, only do it for the first invocation.

7714 Whether the default %destructor/%printer applies to a particular symbol
7715 isn't a question of whether the user *declares* that symbol (in %token,
7716 for example). It's a question of whether the user by any means
7717 *defines* the symbol at all (by simply using a char token, for
7718 example). $end is defined by Bison whereas any other token with token
7719 number 0 is defined by the user. The error token is always defined by
7720 Bison regardless of whether the user declares it with %token, but we
7721 may one day let the user define error as a nonterminal instead.
7722 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
7723 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
7724 the meaning of "user-defined".

8125 by mbswidth) needs the latter.
8126 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to

8237 rule.

8239 since not all symbol declarations may have been parsed yet and, thus,
8240 warnings about types for $$, $n, @$, and @n can't be reported yet.
8241 (packgram): Translate the action and invoke grammar_rule_check now that
8242 all symbol declarations have been parsed.
8243 * src/scan-code.l (handle_action_dollar): Now that this is invoked
8244 after parsing the entire grammar file, the symbol list here in the case
8245 of a midrule is actually the midrule's empty RHS, so reference its
8246 parent rule's RHS where necessary.
8247 On the other hand, now that you can already know it's a midrule, you

8255 terminates a rule. symbol_list_print already does this correctly.
8256 * src/symlist.h (symbol_list.midrule_parent_rule,

8455 The Translation Project changed its way of publishing translations
8456 to maintainers. I haven't received any responses to my request
8457 for supporting the old way, or for documenting the new way. I
8458 have modified 'bootstrap' to use screen scraping
8459 (in this case, HTML scraping). This is unreliable and inelegant,
8460 but I don't see any better way. Yuck.
8461 * bootstrap (TP_URL, WGET_COMMAND): New vars.
8462 (get_translations): New function, which uses HTML scraping to
8463 deduce locations of latest translations.
8464 Use this function to grab both bison and bison-runtime .po files.
8465 Don't bother priming the pump for the runtime-po domain any more,
8466 as it's now translated better than bison is.

9235 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
9236 got from <http://bro-ids.org/download.html>. The bug is that
9237 when two actions appeared in succession, the second one was
9238 scanned before the first one was added to the grammar rule
9239 as a midrule action. Bison then output the incorrect warning
9240 "parse.y:905.17-906.36: warning: unused value: $3".
9241 * src/parse-gram.y (BRACED_CODE, action): These are no longer
9242 associated with a value.

10840 the new runtime-po domain, prime the pump by extracting the

10842 removed once the bison-runtime domain has been translated by each

10880 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10881 remove trailing spaces. This loses the exit status of ./types,
10882 and isn't needed since ./types shouldn't be emitting trailing
10883 spaces.

10902 in the 2005-07-12 change.

10916 Destructor cleanups and regularization among the three skeletons.

10921 * data/glr.c (yyparse): Pop everything off the stack before
10922 freeing it, so that destructors get called properly.

10927 why destructors might be called. 1.875 -> 2.1.

10942 Rename yyoverflowab to yyexhaustedlab.
10943 When memory exhaustion occurs during syntax-error reporting,
10944 report it separately rather than in a single diagnostic; this
10945 eases translation.

10956 can be understood only by someone who can read the
10957 (English-language) source code.
10958
10959 Generate runtime-po/bison-runtime.pot automatically, so that we
10960 don't have to worry about garbage getting in that file. We'll
10961 make sure after the next official release that old msgids don't
10962 get lost. See
10963 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.

10967 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10968 Fix typos in explanations of the runtime file.
10969 * bootstrap: Change gettext keyword from YYI18N to YY_.
10970 Use standard Makefile.in.in in runtime-po, since we'll arrange
10971 for backward-compatible bison-runtime.po files in a different way.
10972 * data/glr.c (YY_): New macro, from yacc.c.
10973 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10974 Translate messages intended for users.
10975 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10976 the wording in the other skeletons. We don't know that the memory
10977 is virtual.
10978 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10979 Use same method that yacc.c uses.
10980 Don't translate debugging messages.
10981 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10982 it doesn't work (yet), and requires C++ expertise to fix.
10983 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10984 Move defn to a more logical place, to be consistent with other
10985 skeletons.
10986 Don't translate debugging messages.
10987 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10988 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10989 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10990 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

11006 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
11007 (yyparse): New local variable yyresult to record the result.

11011 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
11012 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
11013 if YYABORT is used).
11014 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with

12194 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
12195 whether the reducion was empty or not. This leaves room to
12196 improve the use of YYLLOC_DEFAULT in such a case.
12197 lalr1.cc is still experimental, so changing this is acceptable.

12336 output the location within the %printer.
12337 Activate GLR tests, at least to make sure they compile properly.

12344 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
12345 Bison directive from the Bison file to the invocation of this
12346 macro, so that these directives are passed to
12347 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
12348 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
12349 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
12350 the extra Bison directives instead of the whole series.
12351 Change the grammar so that there are recoverable errors, and
12352 unrecoverable errors. Now we can have the parser give up before
12353 consuming the whole input. As a result we now can observe that
12354 the lookahead is freed when needed.
12355 Change the parser source to parse argv[1] instead of a hard coded
12356 string.
12357 Simplify yylex, and give a value and location to EOF.
12358 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
12359 passed directives already coded in the file.
12360 Add some tests to check the location of "error".
12361 For some tests, the C++ parser is correct, and not yacc.c.
12362 For other tests, they provide different, but unsatisfying, values,
12363 so keep the C++ value so that at least one parser is "correct"
12364 according to the test suite.
12365 (Actions after errors): Remove, this is subsumed by the
12366 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

12544 Spent a few hours checking out which prerequisite versions the

12547 a seemingly endless set of combinations of versions more recent
12548 than that. The bottom line is that the current sources require
12549 fairly recent versions of the build tools, and it'll be some work

13066 When reducing initial empty rules, Bison parser read an initial
13067 location that is not defined. This results in garbage, and that
13068 affects Bison's own parser. Therefore we need (i) to extend Bison

13363 Fix a GLR parser bug I reported in February; see

13365 The problem was that GLR parsers did not conform to the C standard,
13366 because actions like { $1 = $2 + $3; } expanded to expressions
13367 that invoked YYFILL in separate subexpressions, and YYFILL assigned
13368 to a local variable. The C standard says that expressions
13369 like (var = f ()) + (var = f ()) have undefined behavior.
13370 Another problem was that GCC sometimes issues warnings that
13371 yyfill and its parameters are unused.
13372
13373 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
13374 as possibly unused.
13375 (yyfill): New function.
13376 (YYFILL): Use it.
13377 (yyuserAction): Change type of yynormal to bool, so that it matches
13378 the new yyfill signature. Mark it as possibly unused.

13381 Follow up on a bug I reported in February, where a Bison-generated
13382 parser can loop. Provide a test case and a fix for yacc.c. I
13383 don't have a fix for lalr1.cc or for glr.c, unfortunately.
13384 The original bug report is in:

13386
13387 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
13388 macro's size was becoming unwieldy.
13389 (yyerrlab): Do not discard an empty lookahead symbol, as this
13390 might destroy garbage.
13391 (yyerrorlab): New label, with the old contents of YYERROR,
13392 plus the following change: pop the stack of rhs corresponding
13393 to the production that invoked YYERROR. That is how Yacc
13394 behaves, and POSIX requires this behavior.
13395 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
13396 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
13397 Define 'alarm' to do nothing if unistd.h is not available.
13398 Add a new rule "exp: '-' error;" to test the above change to
13399 data/yacc.c. Use 'alarm' to abort any test taking longer than
13400 10 seconds, as it's probably looping.
13401 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
13402 Also, the new yacc.c generates two fewer diagnostics for an
13403 existing test.

13757 depend on *loc, so that the reader doesn't give the the false
13758 impression that *loc is initialized.
13759 (<INITIAL>"%%"): Do not bother setting code_start, since its value

13767 then it starts with the second %%'s beginning, instead of its end.

14031 we don't need to worry about yyerrlab1 being reported as an
14032 "unused label" by non-GCC C compilers. The downside is that if
14033 locations are used then a couple of statements are duplicated each
14034 time YYERROR is invoked, but the upside is that the warnings
14035 should vanish.

14055 these elements have fake values.

14162 Switch back to the Yacc style of conflict reports, undoing some

14164 * doc/bison.texinfo (Understanding): Use Yacc style for
14165 conflict reports. Also, use new way of locating rules.

14167 Renamed from conflict_report_yacc, removing the old
14168 'conflict_report'. Translate the entire conflict report at once,
14169 so that we don't assume that "," has the same interpretation in

14171 (conflicts_output): Use Yacc-style conflict report for each state,
14172 instead of our more-complicated style.

14189 This problem was originally reported by Paul Hilfinger in

14192 * data/yacc.c (yyparse): New local var yylerrsp, to record the
14193 top of the location stack's error locations.
14194 (yyerrlab): Set it. When discarding a token, push its location
14195 onto yylerrsp so that we don't lose track of the error's end.
14196 (yyerrlab1): Now is only the target of YYERROR, so that we can
14197 properly record the location of the action that failed. For GCC
14198 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
14199 GCC warning about yyerrlab1 being unused if YYERROR is unused.
14200 (yyerrlab2): New label, which yyerrlab now falls through to.
14201 Compute the error's location by applying YYLLOC_DEFAULT to
14202 the locations of all the symbols that went into the error.
14203 * doc/bison.texinfo (Location Default Action): Mention that
14204 YYLLOC_DEFAULT is also invoked for syntax errors.
14205 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

14207 discarded, not just the last token.

14264 If the user does not define YYSTYPE as a macro, Bison now declares it
14265 using typedef instead of defining it as a macro. POSIX requires this.
14266 For consistency, YYLTYPE is also declared instead of defined.
14267
14268 %union directives can now have a tag before the `{', e.g., the
14269 directive `%union foo {...}' now generates the C code
14270 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
14271 The default union tag is `YYSTYPE', for compatibility with Solaris 9
14272 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
14273 instead of `yyltype'.
14274
14275 `yystype' and `yyltype' are now obsolescent macros instead of being
14276 typedefs or tags; they are no longer documented and will be
14277 withdrawn in a future release.

14285 for backward compatibility.
14286 * data/yacc.c: Likewise.
14287
14288 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
14289 does not specify a union tag. This is for compatibility with
14290 Solaris 9 yacc.

14311 to return when scanning braced code.

14381 Remove unportable casts and storage allocation tricks.
14382 While we're at it, remove almost all casts, since they
14383 usually aren't needed and are a sign of trouble.
14384
14385 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
14386
14387 * src/derives.c (derives_compute): Do not subtract NTOKENS from
14388 the pointer DSET returned by malloc; this isn't portable.
14389 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
14390 Similarly for DERIVES.
14391 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
14392 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
14393 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
14394
14395 * src/derives.c (derives_compute): Do not bother invoking
14396 int_of_rule_number, since rule numbers are integers.
14397
14398 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
14399 rather than XMALLOC (char, N).
14400
14401 * src/files.c (filename_split): Rewrite to avoid cast.
14402
14403 * src/gram.h (symbol_number_as_item_number,
14404 item_number_as_symbol_number, rule_number_as_item_number,
14405 item_number_as_rule_number):
14406 Now inline functions rather than macros, to avoid casts.
14407 * src/state.h (state_number_as_int): Likewise.
14408 * src/tables.c (state_number_to_vector_number,
14409 symbol_number_to_vector_number): Likewise.

14412
14413 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
14414 since the resulting storage is always stored into.
14415
14416 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
14417 where it's needed.
14418

14431 symbol_check_alias_consistency_processor, symbol_pack_processor,

14434 * src/uniqstr.c (uniqstr_print_processor): Likewise.
14435 * src/muscle_tab.c (muscles_m4_output):

14439 symbols_token_translations_init):

14442
14443 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
14444 var instead of casting to long, to avoid casts.
14445 (prepare_states): Use MALLOC rather than alloca, so that we don't
14446 have to worry about alloca.
14447 * src/state.c (state_hash_lookup): Likewise.
14448
14449 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
14450 local var instead of casting to unsigned char, to avoid casts.
14451
14452 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
14453 STATE_ALLOC): Remove.
14454 (transitions_new, errs_new, reductions_new, state_new): Use malloc
14455 rather than calloc, and use offsetof to avoid allocating slightly
14456 too much storage.
14457 (state_new): Initialize all members.
14458
14459 * src/state.c (state_hash): Use unsigned accumulator, not signed.
14460
14461 * src/symtab.c (symbol_free): Remove; unused.

14474 (CALLOC, MALLOC, REALLOC): New macros.
14475 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
14476 new macros.
14477
14478 * src/tables.c (table_size): Now int, to pacify GCC.
14479 (table_grow, table_ninf_remap): Use signed table size.
14480 (save_row): Don't bother initializing locals when not needed.
14481 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
14482 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
14483
14484 * src/vcg.h: Correct misspellings.
14485
14486 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.

14710 processing of Yacc white space and equivalents here.

14712 instead of returning ID immediately, since we need to search for
14713 a subsequent colon.
14714 (<INITIAL>"'", "\""): Save token_start.
14715 (<INITIAL>"%{", "{", "%%"): Save code_start.
14716 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

14917 ((...));' if a single statement is desired (e.g. before `else').

15270 Use new @ escapes consistently. Represent brackets with @{ and @}
15271 rather than @<:@ and @:>@, since this works a bit better with dumb
15272 editors like vi. Represent @ with @@, since @ is now consistently
15273 an escape. Use @oline@ and @ofile@ rather than __oline__ and
15274 __ofile__, to avoid unexpected expansions. Similarly, use @output
15275 rather than #output.
15276
15277 * data/c.m4 (b4_copyright): Omit file name from comment, since
15278 the file name could contain "*/".

15325 them with auto vars.
15326 Switch to new escape scheme, where @ is the escape character uniformly.

15328 buffer when parsing non-escaped text.

15567 as well as \000. Check for UCHAR_MAX, not 255.

15614 indicates one.
15615 * src/output.c (output_skeleton): Use xfclose rather than fclose

15680 decl; not needed any more.
15681 * src/main.c (main): Use return to exit, undoing yesterday's change.
15682 The last OS that we could find where this wouldn't work is
15683 SunOS 3.5, and that's too old to worry about now.
15684
15685 * data/glr.c (struct yyltype): Define members even when not
15686 doing locations. This is more consistent with yacc.c, and it
15687 works around the following bug reports:

15701 Be consistent about 'bool'; the old code used an enum in one
15702 module and an int in another, and this violates the C standard.
15703 * m4/stdbool.m4: New file, from coreutils 4.5.3.
15704 * configure.ac (AC_HEADER_STDBOOL): Add.
15705 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

15729
15730 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
15731 * src/getargs.c (usage): Likewise.
15732

15747 Include <limits.h> unconditionally, since it's guaranteeed even
15748 for a freestanding C89 compiler.

16059 Let nondeterministic skeletons be usable with deterministic
16060 tables.
16061
16062 With the patch, GAWK compiled by GCC without -O2 passes its test
16063 suite using a GLR parser driven by LALR tables. It fails with -O2
16064 because `struct stat' gives two different answers on my machine:
16065 88 (definition of an auto var) and later 96 (memset on this var).
16066 Hence the stack is badly corrumpted. The headers inclusion is to
16067 blame: if I move the awk.h inclusion before GLR's system header
16068 inclusion, the two struct stat have the same size.

19515 not visible.

19533 Don't use %option yylineno: it seems that then Flex imagines
19534 REJECT has been used, and therefore it won't reallocate its
19535 buffers (which makes no other sense to me than a bug). It results
19536 in warnings for `unused: yy_flex_realloc'.

19842 these states are automatically computed from the initial state.
19843 (generate_states): Adjust.
19844 * src/print.c: When reporting a rule number to the user, substract
19845 1, so that the axiom rule is rule 0, and the first user rule is 1.
19846 * src/reduce.c: Likewise.
19847 * src/print_graph.c (print_core): For the time being, just as for
19848 the report, depend upon --trace-flags to dump the full set of
19849 items.
19850 * src/reader.c (readgram): Once the grammar read, insert the rule
19851 0: `$axiom: START-SYMBOL $'.
19852 * tests/set.at: Adjust: rule 0 is now displayed, and since the
19853 number of the states has changed (the final state is no longer
19854 necessarily the last), catch up.

19861 instead of the 0-sentinel.

19875 reductions, then output the report anyway if requested, then die.

19877 * src/reader.c (eoftoken): New.
19878 (parse_token_decl): If the token being defined has value `0', it
19879 is the eoftoken.
19880 (packsymbols): No longer hack `tags' to insert `$' by hand.
19881 Be sure to preserve the value of the eoftoken.
19882 (reader): Make sure eoftoken is defined.
19883 Initialize nsyms to 0: now eoftoken is created just like the others.
19884 * src/print.c (print_grammar): Don't special case the eof token.
19885 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
19886 lie anyway, albeit pleasant.
19887 * tests/calc.at: Exercise error messages with eoftoken.
19888 Change the grammar so that empty input is invalid.
19889 Adjust expectations.

20318 but that's to be addressed elsewhere.
20319 No longer output the rule numbers, but do output the state number.
20320 A single loop for the shifts + gotos is enough, but picked a

20729 Because useless nonterminals are now kept alive (instead of being

20739 `shift_symbol', containing the symbol that can be shifted from a
20740 given state.

20882 * src/bison.simple (YYSTACK_REALLOC): Remove.
20883 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
20884 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
20885 New macros.
20886 (union yyalloc): New type.
20887 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
20888 an arbitrary restriction on hosts where size_t is wider than int.
20889
20890 (yyparse): Don't dump core if alloca or malloc fails; instead, report
20891 a parser stack overflow. Allocate just one block of memory for all
20892 three stacks, instead of allocating three blocks; this typically is
20893 faster and reduces fragmentation.
20894
20895 Do not limit the number of items in the stack to a value that fits
20896 in 'int', as this is an arbitrary limit on hosts with 64-bit
20897 size_t and 32-bit int.

23125 The location tracking mechanism is precious for parse error
23126 messages. Nevertheless, it is enabled only when `@n' is used in

23161 Test also `--verbose', `--defines' and `--name-prefix'. Testing
23162 the latter demonstrates a flaw in the handling of non debugging
23163 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
23164 was used in order to simplify:
23165
23166 #if YYDEBUG
23167 if (yydebug)
23168 {

23175 if (yydebug)
23176 {
23177 ...
23178 }
23179

23232 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
23233 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
23234 difficult and introduced a lot of core dump. It turns out that
23235 Bison used an implementation of `xmalloc' based on `calloc', and
23236 at various places it does depend upon the initialization to 0. I
23237 have not tried to isolate the pertinent places, and all the former
23238 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

24327 declaration to allow a multi-character symbol as an alias.
24328 (parse_thong_decl): New function.

24339 Revised and use multiple warnxxx functions to avoid using VARARGS1.
24340 (read_declarations): Improve the error message for
24341 an invalid character. Do not abort.
24342 (read_declarations, copy_guard, copy_action): Use
24343 printable_version to avoid unprintable characters in printed output.

24369 (lex): Use literalchar.
24370 (lex): Implemented "..." tokens.
24371 (literalchar, lex, parse_percent_token): Made tokenbuffer
24372 always contain the token. This includes growing the token
24373 buffer while reading an integer.
24374 (parse_percent_token): Replaced if-else statement with percent_table.
24375 (parse_percent_token): Added % declarations as another
24376 way to specify the flags -n, -l, and -r. Also added hooks for
24377 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
24378 major changes to files.c.
24379 (lex) Retain in the incoming stream a character following
24380 an incorrect '/'.
24381 (skip_white_space, lex): Revised most error messages
