3 Let yytranslate handle the eof case.
4 * data/lalr1.cc (yytranslate_): Handle the EOF case.
6 No longer expect yychar to be equal to yyeof_, rather, test the
7 lookahead's (translated) kind.
9 2008-11-11 Akim Demaille <demaille@gostai.com>
11 yychar cannot be empty in yyerrlab.
12 * TODO (yychar == yyempty_): New.
13 * data/lalr1.cc: Remove the handling of this case.
14 This eases forthcoming changes related to yychar and yytranslate.
16 2008-11-11 Akim Demaille <demaille@gostai.com>
18 Bench: syntactic sugar for %define/#define.
19 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
20 (&bench_push_parser, bench_variant_parser): Use this feature.
24 2008-11-11 Akim Demaille <demaille@gostai.com>
26 Less memory pressure on the "list" bench.
27 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
28 the values, to limit memory pressure.
30 2008-11-11 Akim Demaille <demaille@gostai.com>
32 Introduce make_symbol.
33 make_symbol provides a means to construct a full symbol (kind, value,
34 location) in a single shot. It is meant to be a Symbol constructor,
35 parameterized by the symbol kind so that overloading would prevent
36 incorrect kind/value pairs. Unfortunately parameterized constructors do
37 not work well in C++ (unless the parameter also appears as an argument,
38 which is not acceptable), hence the use of a function instead of a
41 * data/lalr1.cc (b4_symbol_constructor_declaration_)

43 (b4_symbol_constructor_specialization_)
44 (b4_symbol_constructor_specializations)
45 (b4_symbol_constructor_definition_)
46 (b4_symbol_constructor_definitions): New.
47 Use them where appropriate to generate declaration, declaration of
48 the specializations, and implementations of the templated
49 overloaded function "make_symbol".
50 (variant::variant): Always define a default ctor.
51 Also provide a copy ctor.
52 (symbol_base_type, symbol_type): New ctor overloads for value-less

59 Inform m4 whether a tag is a valid id.
60 * src/output.c (is_identifier): New.
61 (symbol_definitions_output): Use it to define tag_is_id.
62 But maybe this should be done at m4 level?
64 2008-11-11 Akim Demaille <demaille@gostai.com>
66 Test 214 was failing: it greps with a pattern containing [ ]*
67 which obviously meant to catch spaces and tabs, but contained only
68 spaces. Tabulations in sources are a nuisance, so to simplify the
69 matter, get rid of all the tabulations in the Java sources. The
70 other skeletons will be treated equally later.
72 * data/java.m4, data/lalr1.java: Untabify.
73 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
74 tabulations are no longer generated.

189 2008-11-10 Akim Demaille <demaille@gostai.com>
191 Make parser::yytranslate static.
192 Small speedup (1%) on the list grammar. And makes yytranslate_ available
193 in non member functions.

200 Avoid trailing spaces.
201 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
202 * data/lalr1.cc: Don't indent before rule and symbol actions, as
203 they can be empty, and anyway this incorrectly indents the first

252 2008-11-10 Akim Demaille <demaille@gostai.com>
254 Change the handling of the symbols in the skeletons.
255 Before we were using tables which lines were the symbols and which
256 columns were things like number, tag, type-name etc. It is was
257 difficult to extend: each time a column was added, all the numbers had
258 to be updated (you asked for colon $2, not for "tag"). Also, it was
259 hard to filter these tables when only a subset of the symbols (say the
260 tokens, or the nterms, or the tokens that have and external number
261 *and* a type-name) was of interest.
263 Now instead of monolithic tables, we define one macro per cell. For
264 instance "b4_symbol(0, tag)" is a macro name which contents is
265 self-decriptive. The macro "b4_symbol" provides easier access to
268 * src/output.c (type_names_output): Remove.
269 (symbol_numbers_output, symbol_definitions_output): New.
270 (muscles_output): Call them.
271 (prepare_symbols): Define b4_symbols_number.

310 Use it with and without %define assert.
312 2008-11-10 Akim Demaille <demaille@gostai.com>
314 Add %precedence support.
315 Unfortunately it is not possible to reuse the %prec directive. This
316 is because to please POSIX, we do not require to end the rules with a
317 semicolon. As a result,
321 is ambiguous: either a rule which precedence is that of baz, or a rule,
322 and then a declaration of the precedence of the token baz.
324 * doc/bison.texinfo: Document %precedence.
325 (Precedence Only): New.
326 * src/assoc.h, src/assoc.c (precedence_assoc): New.

448 (parser::yyla): this.
450 2008-11-09 Akim Demaille <demaille@gostai.com>
452 Rely on the state stack to display reduction traces.
453 To display rhs symbols before a reduction, we used information about the rule
454 reduced, which required the tables yyrhs and yyprhs. Now use rely only on the
455 state stack to get the same information.
457 * data/lalr1.cc (b4_rhs_data, b4_rhs_state): New.
459 (parser::yyrhs_, parser::yyprhs_): Remove.

583 Add "%define assert" to variants.
584 This is used to help the user catch cases where some value gets
585 ovewritten by a new one. This should not happen, as this will
588 Unfortunately this uncovered a bug in the C++ parser itself: the
589 lookahead value was not destroyed between two calls to yylex. For
590 instance if the previous lookahead was a std::string, and then an int,
591 then the value of the std::string was correctly taken (i.e., the
592 lookahead was now an empty string), but std::string structure itself
595 This is now done in variant::build(other&) (which is used to take the
596 value of the lookahead): other is not only stolen from its value, it
597 is also destroyed. This incurs a new performance penalty of a few
598 percent, and union becomes faster again.

879 Fuse the three stacks into a single one.
880 In order to make it easy to perform benchmarks to ensure that there are no
881 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
882 lalr1-fusion.cc will replace lalr1.cc.
884 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
885 test suite, the user must install a symbolic link from lalr1.cc to it.
887 Instead of having three stacks (state, value, location), use a stack
888 of triples. This considerably simplifies the code (and it will be
889 easier not to require locations as currently does the C++ parser),
890 and also gives a 10% speedup according to etc/bench (probably mainly since
891 memory allocation is done once instead of three times).
893 Another motivation is to make it easier to destruct properly
894 semantic values: now that they are bound to their state (hence
895 symbol type) it will be easier to call the appropriate destructor.
897 These changes should probably benefit the C parser too.
899 * data/lalr1.cc: Copy as... * data/lalr1-fusion.cc: this new
901 (b4_rhs_value, b4_rhs_location): New definitions overriding those
903 (state_stack_type, semantic_stack_type, location_stack_type)
904 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
905 (data_type, stack_type, yystack_): New.
906 (YYLLOC_DEFAULT, yypush_): Adjust.
907 (yyerror_range): Now based on data_type, not location_type.
909 2008-11-03 Akim Demaille <demaille@gostai.com>
911 Push the state, value, and location at the same time.
912 This is needed to prepare a forthcoming patch that fuses the three
915 * data/lalr1.cc (parser::yypush_): New.
916 (parser::yynewstate): Change the semantics: instead of arriving to
917 this label when value and location have been pushed, but yystate
918 is to be pushed on the state stack, now the three of them must
919 have been pushed before. yystate still must be the new state.
920 This allows to use yypush_ everywhere instead of individual
921 handling of the stacks.
923 2008-11-03 Akim Demaille <demaille@gostai.com>
925 Prefer references to pointers.
926 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
927 definition to use references instead of pointers.

929 Take the value and location as references.

942 Use variants to support objects as semantic values.
943 This patch was inspired by work by Michiel De Wilde. But he used Boost
944 variants which (i) requires Boost on the user side, (ii) is slow, and
945 (iii) has useless overhead (the parser knows the type of the semantic value
946 there is no reason to duplicate this information as Boost.Variants do).
948 This implementation reserves a buffer large enough to store the largest
949 objects. yy::variant implements this buffer. It was implemented with
952 * src/output.c (type_names_output): New.

957 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
958 (b4_char_sizeof, yy::variant): New.
959 (parser::parse): If variants are requested, define
960 parser::union_type, parser::variant, change the definition of
961 semantic_type, construct $$ before running the user action instead
962 of performing a default $$ = $1.
963 * examples/variant.yy: New.
964 Based on an example by Michiel De Wilde.
966 2008-11-03 Akim Demaille <demaille@gostai.com>
968 Parameterize the extraction of semantic values.

1269 * data/m4sugar/m4sugar.m4 (changeword): Nuke.
1270 (m4_prepend): Remove, as it is unused and inherently quadratic,
1271 whereas m4_append is linear in newer m4.
1272 (m4_mkstemp): New builtin.
1273 (m4_symbols): Make rename conditional.
1274 (m4_version_prereq): Ensure fatal error if used in bison, which

1324 Fix dependence on computed configure variables.
1325 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
1326 $(top_srcdir)/configure.ac so that changes to computed variables, such
1327 as PACKAGE_VERSION, are seen.
1328 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1330 2008-07-20 Joel E. Denny <jdenny@ces.clemson.edu>

1352 * NEWS (2.3b+): Rename to...
1353 (?.?): ... this because we're dropping the "+" version naming scheme,
1354 but, in general, we still can't be sure of our next release name.
1355 * bootstrap: Add a quick hack to remove from .gitignore the
1356 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
1357 entry. This should really be fixed in gnulib instead.
1358 * bootstrap.conf (gnulib_modules): Add gnumakefile.
1359 * configure.ac (AC_INIT): Set version name by invoking
1360 build-aux/git-version-gen.

1386 (Empty Language): Likewise.
1388 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
1390 Fix some .gitignore and .cvsignore problems.
1391 * bootstrap (insert_sorted_if_absent): Replace all uses with...
1392 (insert_vc_ignore): ... this new function, which prepends `/' to all
1393 .gitignore entries before passing them to insert_sorted_if_absent.
1394 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1395 .cvsignore files are maintained even though Bison developers run
1396 bootstrap while using Git.
1397 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
1400 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
1401 unneeded. Reported by Eric Blake.

1404 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
1406 * src/.gitignore (/bison.exe): Add. Reported by Eric Blake.
1408 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
1410 Improve forward-compatibility with GNU M4. Reported by Eric Blake at
1411 <http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>.

1414 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
1416 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
1417 the first argument because it may become position-dependent, and unset
1418 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
1419 Add comments explaining these issues in more detail.
1421 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>
1423 Add .gitignore everywhere based on .cvsignore.

1454 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>
1456 * HACKING: Don't say don't mention HACKING in the ChangeLog. We've

1475 coordinator@translationproject.org.
1477 2008-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1479 * THANKS: Add Eric Blake.
1481 2008-04-23 Eric Blake <ebb9@byu.net>
1483 Revert prior patch, by working around autoconf regression.
1484 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
1485 ("Output file name: ("): Uncomment test.
1486 ("Output file name: )"): Likewise.
1487 Based on an idea from Noah Misch.
1489 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

1492 2.61. Reported by Juan Manuel Guerrero at
1493 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
1494 * tests/output.at ("Output file name: ("): Comment out test case for
1496 ("Output file name: )"): Likewise.
1498 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
1500 * GNUmakefile: Update git-version-gen invocation so make dist
1503 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
1505 Update to the current gnulib CVS repository, and fix trigraph handling
1507 * bootstrap: Update gnulib CVS repository URL.
1508 (symlink_to_dir): Encapsulate the code that guarantees the destination
1509 directory exists into...
1510 (check_dst_dir): ... this new function, and...
1511 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
1512 fail when copying files into lib/uniwidth/.
1513 * src/output.c (prepare_symbols): When writing yytname muscles, where
1514 symbol names will be encoded in C-string literals, tell quotearg to
1515 escape trigraphs. This used to be the default in gnulib.
1516 * tests/regression.at (Token definitions): Because of the change in
1517 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
1518 escapes trigraphs in symbol names. Thus, yytname no longer has
1519 trigraphs unnecessarily doubly escaped. Update test case output.
1520 Extend test case to be sure Bison's own error messages will no longer
1521 have trigraphs in symbol names unnecessarily escaped once.
1523 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>
1525 Fix make dist infinite loop reported by Juan Manuel Guerrero at

1533 2008-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
1535 * NEWS (2.3a+): Mention that -g now takes an argument.
1536 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
1537 consistency. Update the -g and -x entries now that they take
1538 arguments. Use brackets to indicate optional arguments.
1539 * src/getargs.c (usage): Explain the relationship between arguments of
1540 long and short options more completely. Document --defines and -d
1541 separately since the former takes an argument but, for POSIX Yacc, the
1543 (short_options): Let -W take an optional argument like --warnings.
1544 (getargs): Sort cases.

1558 -g and -x take optional arguments, just like their long options.
1559 * build-aux/cross-options.pl: Use /x to make the regexp easier to
1561 Fix the handling of $opt which resulted in all the argument to be
1562 considered as optional.
1564 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
1566 * NEWS (2.3a+): Don't say %language is experimental. Mention Java and
1567 say its interface is experimental.
1568 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
1570 (Bison Options): In the -L and --language entry, mention Java.
1571 (Java Bison Interface): Say the interface is experimental.
1572 * src/getargs.c (usage): Mention -L and --language.
1574 * NEWS (2.3a+): Say the push parsing interface is experimental.

1598 Fix impure push parser compile error reported by Bob Rossi at
1599 <http://lists.gnu.org/archive/html/help-bison/2008-02/msg00023.html>.
1600 * data/yacc.c: Clean up whitespace in the output a little.
1601 (yypstate_allocated): Define for impure push parsers regardless of
1602 whether the pull interface is also requested.
1603 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
1604 check impure push parsers without the pull interface.
1606 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
1607 yyerror takes arguments specified by %parse-param while yypstate_new

2298 parsing requests here...
2299 * data/yacc.c: ... hack this to switch to push.c any time

2301 will go away when we mv push.c yacc.c.
2302 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2303 push parsing is not supported since unused %define variables are

2514 Get rid of broken %no-parser, -n, and --no-parser implementation and
2516 * TODO: Don't mention them.
2517 * doc/bison.1: Likewise.
2518 * doc/bison.texinfo (Decl Summary): Likewise.
2519 (Bison Options): Likewise.
2520 (Option Cross Key): Likewise.
2521 * src/getargs.c (no_parser_flag): Remove global variable.
2522 (usage): Don't print description of -n and --no-parser.
2523 (long_options): Remove --no-parser entry here.
2524 (getargs): Remove -n case in the switch here.
2525 * src/getargs.h (no_parser_flag): Remove extern.
2526 * tests/regression.at (Web2c Actions): Remove comment that mentions
2529 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2531 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
2532 name user variables starting with `yy'. Just pass NULL instead of a
2533 dummy local &yylval to yypush_parse.
2534 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
2537 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
2539 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
2540 true since it's then always used regardless of whether yyoverflow is
2541 defined. Reported by Christian Burger at
2542 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
2543 * THANKS: Add Christian Burger.
2545 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2546 node names: say "Decl Summary" not "Bison Declaration Summary".
2548 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
2550 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
2551 determine whether this function has already complained about an invalid
2552 value for a %define boolean variable, don't check whether Bison has
2553 ever examined the value. As written, the check was a tautology.
2554 Instead, record and check for this complaint using a separate muscle.
2556 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
2558 Fix push parsing memory leak reported by Brandon Lucia at
2559 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
2560 * THANKS: Add Brandon Lucia.
2561 * data/push.c (yypstate_delete): Free the stack if it was reallocated
2562 but the parse never completed and thus freed it.
2563 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
2564 * tests/testsuite.at: Include push.at.
2565 * test/push.at: New.
2566 (Push Parsing: Memory Leak for Early Deletion): New test case.
2568 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
2570 Improve handling of multiple S/R conflicts in the same state and of S/R
2571 conflicts involving multiple reductions.
2572 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
2573 set for a state here or Bison will abort if it is reassigned on a
2574 later conflicted reduction in the same state.
2575 Similarly, don't finalize and assign the solved conflicts report here
2576 or it will be lost if it is reassigned on a later conflicted reduction
2578 (set_conflicts): Instead, assign them both here after all S/R conflicts
2579 in the state have been fully examined.
2580 * src/print.c (shift_set): Rename to...
2581 (no_reduce_set): ... this.
2582 (print_reductions): Update for rename, and add %nonassoc error action
2583 tokens to no_reduce_set so that, when printing the first remaining
2584 reduction on an error action token, the reduction is enclosed in
2586 (print_results): Update for rename.
2587 * tests/conflicts.at (Solved conflicts report for multiple reductions
2588 in a state): New test case.
2589 (%nonassoc error actions for multiple reductions in a state): New test
2592 * src/main.c (main): Don't depend on C99 features.
2594 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
2596 * build-aux/.cvsignore: Add compile.
2597 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2600 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2602 * bootstrap (slurp): Create target directories that don't exist.
2603 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2605 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2607 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2609 * closure.c (closure): Likewise.
2610 * state.h (reductions): Comment sorting of rules.
2611 (state): Comment sorting of items.
2613 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2615 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2616 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2617 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2618 definition in order to avoid Gnulib headers since we don't use config.h
2620 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2621 rather than AT_DATA so that config.h is included.
2623 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2625 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2626 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2627 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2628 and so that YYFPRINTF is guaranteed to be defined here.
2630 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2632 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2634 (muscle_percent_define_check_values): ... this more helpful function.
2635 Again, it's not used yet, but it will be.
2636 * src/muscle_tab.h: Likewise.
2638 Improve some comments in parser table construction.
2639 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2640 (generate_states): Don't mention ruleset, which is internal to closure.
2641 * src/closure.c (closure): Explain sorting of core and itemset, which
2642 is required for this function to behave correctly.
2643 * src/closure.h (closure): Mention sorting.
2645 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2647 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2648 move the check for disabled transitions to an aver since conflict
2649 resolution hasn't happened yet.
2651 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2652 labels a state as inconsistent just because it has error transitions.
2653 The original form of this check appeared in revision 1.1 of lalr.c,
2654 which was committed on 1991-12-21. Now (at least), changing the
2655 consistency label on such a state appears to have no useful effect in
2656 any of the places it is examined, which I enumerate below. The key
2657 point to understanding each item in this enumeration is that a state
2658 with an error transition is labelled consistent in the first place only
2659 if it has no rules, so the check cannot matter for states that have
2660 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2661 to try to identify its conflicts, and a state must have *rules* to have
2662 conflicts. (2) Labelling a state as inconsistent will affect how
2663 action_row sets the default *rule* for the state. (3) Labelling a
2664 state as inconsistent will cause build_relations to add lookback edges
2665 to *rules* in that state.
2666 * src/state.h (struct state): Word the comment for member consistent
2669 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2671 Don't depend on C99 features.
2672 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2673 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2674 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2675 * src/state.c (state_mark_reachable_states): Fix for-loop.
2676 (state_remove_unreachable_states): Fix for-loop.
2678 Don't widen struct state with member reachable just to temporarily
2679 record reachability. Instead, use a local bitset.
2680 * src/state.h (struct state): Remove member.
2681 * src/state.c (state_new): Don't initialize it.
2682 (state_mark_reachable_states): Rename to...
2683 (state_record_reachable_states): ... this, and use bitset.
2684 (state_remove_unreachable_states): Use bitset.
2686 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2688 * src/Makefile.am (yacc): Quote target action commands properly so
2689 that the yacc script isn't corrupt. Reported by Hans Aberg at
2690 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2692 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2693 the case of pure parsers. Reported by Frans Englich at
2694 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2695 * THANKS: Add Frans Englich.
2697 * NEWS (2.3a+): In the %code entry, reference section `Bison
2698 Declaration Summary' from the manual now since the %code summary has
2700 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
2701 in the rules section must be terminated by semicolons.
2703 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2705 Extend the front-end API for %define variables to more completely
2706 mirror the back-end. This will be useful in the future.
2707 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
2708 Update comments to mention the new front-end counterparts of these
2710 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

2720 * src/muscle_tab.h (muscle_percent_define_get,
2721 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
2724 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2726 * NEWS (2.3a+): Mention yesterday's state-removal change.
2727 (2.3a): Remove the %language entry, which was added after 2.3a.
2728 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
2729 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
2730 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
2731 tests/existing.at: Update copyright date.
2733 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2735 If conflict resolution makes states unreachable, remove those states,
2736 report rules that are then unused, and don't report conflicts in those

2753 an unused rule is discovered.
2755 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2757 Minor code cleanup in parser table construction.
2758 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
2759 (new_itemsets, save_reductions): Update for rename to nitemset.
2760 * src/closure.c (nritemset): Rename to...
2761 (nitemset): ... this since the "r" appears to meaningless and isn't
2762 used in the comments.
2763 (closure): Update for rename.
2764 * src/closure.h (nritemset): Update extern to...
2765 (nitemset): ... this.

2862 muscle_percent_define_default): New functions mimicking
2863 b4_percent_define_flag_if and b4_percent_define_default.
2865 For %define variables, report locations for invalid values and

2890 * src/print.c (lookahead_set, state_default_rule): Remove.
2891 (print_reductions): Replace state_default_rule invocation with
2892 equivalent use of yydefact, which was computed in token_actions in
2894 (print_results): Don't allocate lookahead_set.
2896 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2898 * data/lalr1.java: Prefix all private members with yy.
2900 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2902 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2903 Sebastien Fricker at
2904 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
2905 * THANKS: Add Sebastien Fricker.

2920 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2922 Undo my 2007-02-07 change, switching back to the c-strcase module
2923 introduced in the 2007-02-03 change. Bruno Haible reported that
2924 the 2007-02-07 change would be dangerous in Turkish if we add a
2925 language whose name contains "i", since "i" is not lowercase "I"
2927 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2928 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

2948 * src/reader.c (packgram): Move translation of rule actions from the
2949 beginning of packgram to...
2950 (check_and_convert_grammar): ... here right before packgram is invoked
2951 so it's easier to write more complete comments, and remove redundant
2954 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2956 As in semantic actions, make @$ in %initial-action, %destructor, and
2957 %printer imply %locations.
2958 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2960 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2961 (@$ in %initial-action implies %locations,
2962 @$ in %destructor implies %locations,
2963 @$ in %printer implies %locations): ... these new test cases.
2965 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2967 Undo most of the 2007-02-03 change, switching to the strcase module
2968 now that gnulib strcase has been fixed.
2969 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2970 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2971 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2972 * m4/.cvsignore: Add strcase.m4.
2973 * src/getargs.c: Revert 2007-02-03 change, as follows.
2974 Don't include c-strcase.h.
2975 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2976 strcasecmp has "unspecified behavior" outside the POSIX locale,
2977 but it works fine in practice if at least one argument is ASCII,
2978 as is the case in Bison.
2980 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2982 * tests/java.at: Skip tests if only one of javac/java is present.
2983 Reported by Joel E. Denny.
2984 * tests/atlocal.in: Adjust copyright years.
2986 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2988 * data/lalr1.java (Stack): Work around old verifiers that disallow
2989 access to the private fields of an inner class, from the outer class.
2990 We can make Stack's fields public because user code doesn't have access
2991 to the instance of Stack used by parse(). Reported by Paul Eggert.
2993 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2995 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2996 the right spot for these files?
2997 * bootstrap.conf (gnulib_modules): Add c-strcase.
2998 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
3000 * src/getargs.c: Include c-strcase.h.
3001 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
3002 to avoid unspecified behavior.
3004 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
3006 * doc/bison.texinfo (Decl Summary): Correct typo.
3008 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
3010 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
3011 Complain if the value does not match empty, "true" or "false".
3012 * data/c++.m4: Adjust default definitions of %define variables.
3013 * data/java.m4: Adjust default definitions of %define variables.
3014 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
3016 * tests/input.at (Boolean %define variables): Test new behavior.
3018 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
3020 * NEWS: Mention java.
3021 * TODO: Remove things that are done.
3022 * bootstrap.conf: Add javacomp-script and javaexec-script.
3023 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
3025 * data/Makefile.am: Add new files.
3026 * data/java-skel.m4: New.
3027 * data/java.m4: New.
3028 * data/lalr1.java: New.
3030 * doc/bison.texinfo: Put "A Complete C++ Example" under
3031 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
3032 under Other Languages.
3034 * src/getargs.c (valid_languages): Add Java.
3035 * src/getargs.h (struct bison_language): Update size of string fields.
3037 * tests/Makefile.am: Add java.at.
3038 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
3039 * tests/java.at: New.
3040 * tests/testsuite.at: Include it.
3042 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
3045 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3046 at_directive_argv arguments so these no longer have to be global
3047 variables. Also, update the implementation for the following changes.
3048 (fail_for_at_directive_too_many_args,
3049 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3050 (at_directive_name): Remove as at_directive_argv[0] will be used for
3052 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3053 for the directive name.
3054 (at_directive_argc, at_directive_argv): Make these local within
3055 skel_lex instead of global.
3056 (INITIAL): Update directive start action for above changes.
3057 (SC_AT_DIRECTIVE_ARG): Rename to...
3058 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
3059 (SC_AT_DIRECTIVE_SKIP_WS): Update.
3060 (scan_skel): Move yylex_destroy to...
3061 (skel_scanner_free): ... here.
3062 * tests/skeletons.at (installed skeleton file name): Rename to...
3063 (installed skeleton file names): ... this.
3065 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3067 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3068 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3069 Summary" not "Directives".
3070 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3071 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3072 since the former is now the more complete one.
3073 (Prologue Alternatives): Likewise and do the same for %defines.
3074 (Table of Symbols): Add summary of %code, add summary of %define, and
3075 move full %code documentation to...
3076 (Decl Summary): ... here for consistency with other entries in these
3078 Move %define entry in order to keep this list alphabetized.
3079 Reword %define entry a little to put less emphasis on the skeleton
3080 concept, which most users shouldn't have to think about.
3082 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3084 Adjust to recent gnulib changes.
3085 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
3086 Add string.h, string_.h, unistd_.h, wchar_.h.
3087 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
3088 * src/system.h: Don't include <stpcpy.h>; this is now done by
3091 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
3093 Simplify implementation of unqualified %code, implement macros for
3094 uniform treatment of boolean %define flags. Document %define.
3095 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
3096 b4_percent_code_ifdef): New.
3097 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
3098 * data/c++.m4: Define default value for global_tokens_and_yystype.
3099 * data/glr.cc: Likewise.
3100 * data/location.cc: Use b4_percent_define_flag_if.
3102 * doc/bison.texinfo (Decl Summary): Document %define.
3104 * src/parse-gram.y (Unqualified %code): Change muscle name to
3106 (content.opt): Default to empty.
3108 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3110 Implement support for relative and absolute skeleton file names.
3111 Discussed starting at
3112 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
3113 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
3114 (Bison Options): Document in --skeleton entry.
3115 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
3116 full_skeleton can't necessarily hold all of pkgdatadir.
3117 If the specified skeleton file name contains a `/', don't prepend
3119 * src/parse-gram.y (prologue_declaration): If the specified skeleton
3120 file name contains a `/', prepend the grammar file directory.
3121 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
3122 * skeletons.at: New file.
3123 (relative skeleton file names): New test case.
3124 (installed skeleton file names): New test case.
3125 * tests/testsuite.at: Include skeletons.at.
3127 * bootstrap: Update copyright to 2007.
3129 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
3131 * bootstrap: Remove occurrences of .#bootmp from the files.
3133 2007-01-17 Akim Demaille <akim@epita.fr>
3135 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
3137 Use per-type %printer.
3139 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3141 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

3149 2007-01-16 Akim Demaille <akim@epita.fr>
3151 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
3153 (Calc++ Scanner): Exit with failure if we can't open the input
3155 Accept "-" standing for stdin.
3156 (Calc++ Top Level): Print the result only if the parsing was
3159 2007-01-16 Akim Demaille <akim@epita.fr>
3161 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
3163 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
3164 and Joel E. Denny <jdenny@ces.clemson.edu>
3166 Clean up %define and %code implementation in M4 some. Most
3167 importantly, rename all related macros to be in the b4_percent_define
3168 and b4_percent_code namespaces. Also, complete support for `.' in
3169 %define variable names and %code qualifiers.
3170 * data/bison.m4 (b4_check_user_names): Check for special
3171 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3173 (b4_get_percent_define, b4_get_percent_code): Rename to...
3174 (b4_percent_define_get, b4_percent_code_get): ... these.
3175 Extend documentation with examples.
3176 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3177 b4_percent_define_skeleton_variables and
3178 b4_percent_code_skeleton_qualifiers.
3179 Expect any value for the %define variable `foo' to be stored in the
3180 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3181 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3182 expect any unqualified %code blocks to be stored in a macro named
3183 `b4_percent_code_unqualified'.
3184 Use m4_indir so that %define variable names and %code qualifiers can
3185 contain `.', which is allowed by the grammar parser.
3186 (b4_percent_define_default): New macro to set a default value for a
3188 (m4_wrap): Update wrapped code, and fix some underquoting.
3189 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3190 Expect grammar uses of %define variables and %code qualifiers to be
3191 defined in b4_percent_define_user_variables and
3192 b4_percent_code_user_qualifiers.
3193 * data/c++.m4: Use b4_percent_define_default rather than
3194 m4_define_default. Fix some underquoting. Skeleton usage of %define
3195 variable define_location_comparison now implies skeleton usage of
3196 %define variable filename_type.
3197 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3198 data/push.c, data/yacc.c: Update macro names.
3199 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3202 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3204 DJGPP specific issues.
3206 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3207 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3209 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3211 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3212 run parsers in all tests so that Valgrind is invoked during
3213 maintainer-check-valgrind.
3214 (Duplicate representation of merged trees): Free all semantic values.
3215 (Duplicated user destructor for lookahead): Likewise.
3217 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3219 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3220 command-line prefix.
3221 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3222 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3223 miss Valgrind messages.
3224 (Exploding the Stack Size with Malloc): Likewise.
3226 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3228 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3229 locals. Reported by Juan Manuel Guerrero at
3230 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3231 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3232 Fix some indentation also.
3233 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3234 explaining this issue.
3236 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3237 and Joel E. Denny <jdenny@ces.clemson.edu>
3239 Simplify union and prologue handling, and escape union and lex/parse
3240 params with digraphs.
3241 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3242 values to the empty string since these are no longer guaranteed
3243 initialized by the front-end.
3244 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3245 braces around b4_user_stype since this is no longer done by the
3247 * src/files.c, src/files.h (pre_prologue_obstack,
3248 post_prologue_obstack): Remove.
3249 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3250 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3251 with digraphs. This fixes lex params and parse params.
3252 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3253 * src/output.c (prepare): Remove muscle insertion of the prologues.
3254 (output): Remove freeing of pre_prologue_obstack and
3255 post_prologue_obstack.
3256 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3257 than prologue_augment for prologue parsing so you don't need prologue
3259 (grammar_declaration): For %union RHS, use `braceless' instead of
3260 "{...}" so that braces are already stripped and code is escaped with
3262 * src/reader.c (prologue_augment): Remove.
3263 (reader): Remove initialization of pre_prologue_obstack and
3264 post_prologue_obstack.
3265 * src/reader.h (prologue_augment): Remove.
3267 * data/c.m4: Remove stray parenthesis.
3269 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3271 Remove quotes from variables names in %define directives and from
3272 qualifiers in %code directives, and restrict the characters that are
3273 allowed in them to M4-friendly ones. For %define, continue to support
3274 the quoted form as a deprecated feature. Discussed starting at
3275 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3276 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3278 * doc/bison.texinfo (Prologue Alternatives): Update.
3279 (Decl Summary): In %defines entry, update mention of `%code requires'
3280 and `%code provides'.
3281 (C++ Location Values): Update %define uses.
3282 (Calc++ Parser Interface): Likewise.
3283 (Calc++ Parser): Likewise, and update `%code requires' uses.
3284 (Table of Symbols): Update %code documentation.
3285 * src/parse-gram.y (prologue_declaration): For %define variables, use
3286 `variable' instead of `STRING'.
3287 (grammar_declaration): For %code qualifiers, use `ID' instead of
3289 (variable): New nonterminal that takes an `ID' or a `STRING'.
3290 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3292 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3293 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3294 (%define errors): Update %define uses.
3296 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3298 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3299 instead of muscle_insert for %define values so that M4-special
3300 characters are replaced with digraphs.
3301 * tests/input.at (%define errors): Extend to check weird values.
3303 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3305 Instead of having skeletons declare all valid %define variables and
3306 %code qualifiers, provide macros that retrieve the associated values
3307 and build these lists automatically. Thus Bison will now warn when a
3308 variable or qualifier is not used by the skeleton in the current
3309 invocation regardless of whether it might sometimes be used by that
3310 skeleton in other invocations. Also, move all %define value macros to
3311 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3312 form, which is replaced by %code.
3313 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3314 (b4_check_user_names): ... this, and change the series of valid name
3315 arguments to a single list argument for names used in the skeleton
3316 similar to the existing list argument for names used in the grammar.
3317 Warn instead of complaining.
3318 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3319 values and %code code, to format %code code properly, and to build
3320 lists of all %define variables and %code qualifiers used in the
3321 skeleton: b4_skeleton_percent_define_variables and
3322 b4_skeleton_percent_code_qualifiers.
3323 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3325 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3326 the skeleton names lists can finish building first. In place of
3327 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3328 expect the lists b4_user_percent_define_variables and
3329 b4_user_percent_code_qualifiers.
3330 * data/c++.m4: Where setting default values for b4_parser_class_name,
3331 b4_location_type, b4_filename_type, b4_namespace, and
3332 b4_define_location_comparison, update their names to the
3333 b4_percent_define_ namespace.
3334 * data/glr.c: Don't use b4_check_percent_define_variables and
3335 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3336 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
3337 (b4_parser_class_name, b4_namespace): Define these using
3338 b4_get_percent_define for parser_class_name and namespace.
3339 * data/location.cc: Use b4_get_percent_define.
3340 * data/push.c: Don't use b4_check_percent_define_variables and
3341 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3342 * data/yacc.c: Likewise, and don't call m4_exit in
3343 b4_use_push_for_pull_if or m4_wrap code will never execute.
3344 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3346 (muscle_grow_user_name_list): ... this for consistency with the
3347 terminology used in bison.m4.
3348 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3349 %define variable names, and rename muscle used_percent_define_variables
3350 to user_percent_define_variables.
3351 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3352 user_percent_code_qualifiers.
3354 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
3355 {CODE} form is no longer accepted.
3356 * tests/input.at (Reject bad %code qualifiers): Rename to...
3357 (Reject unused %code qualifiers): ... this, and update test output.
3358 (%define error): Update test output.
3360 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
3362 Check for unrecognized %define variables similar to checking for
3363 unrecognized %code qualifiers. Check for redefined %define variables.
3364 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3366 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3367 (b4_check_percent_define_variables): New, also wraps it.
3368 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3369 variables using b4_check_percent_define_variables.
3370 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3371 all those exercised in the test suite and all those listed in the
3372 `Default values' section of c++.m4. Are there others?
3373 * data/push.c, data/yacc.c: Declare no valid %define variables.
3374 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3375 similar to muscle_find, but it works even when the muscle stores a
3377 (muscle_grow_used_name_list): New function for constructing the used
3378 name list muscles that b4_check_for_unrecognized_names requires.
3379 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3380 %define'd more than once. Define the b4_used_percent_define_variables
3381 muscle with muscle_grow_used_name_list.
3382 (grammar_declaration): Abbreviate %code code with
3383 muscle_grow_used_name_list.
3384 * tests/input.at (%define errors): New.
3386 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3388 Provide warn_at, complain_at, and fatal_at function callbacks to the
3389 skeletons, and use this for %code qualifier complaints.
3390 * data/bison.m4 (b4_error_at): New, invoked by...
3391 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3392 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3393 @fatal_at(...@) directives.
3394 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3395 qualifiers in b4_used_percent_code_qualifiers and to use
3397 * src/location.c, src/location.h (boundary_set_from_string): New global
3399 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3401 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3402 to b4_used_percent_code_qualifiers.
3403 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3405 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3406 (lineno): Rename to...
3407 (out_lineno): ... this so I don't misunderstand it again.
3408 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3409 here; these newlines are in the input but not the output file.
3410 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3411 (at_directive_perform): ... this new static function, and add handling
3412 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3414 * tests/input.at (Reject bad %code qualifiers): Update test output with
3415 locations and extend.
3417 * tests/output.at (Output file name: [, Output file name: ]): Remove
3418 bogus comment about these tests failing.
3420 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3422 Clean up b4_check_percent_code_qualifiers a little.
3423 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3424 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3425 documentation and add examples.
3426 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
3429 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3431 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
3432 unreliable -- especially when they're hidden inside another macro.
3433 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
3434 data/c.m4: Remove m4_divert(-1).
3435 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3436 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
3437 m4_divert_push(0) and m4_divert_pop(0).
3438 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
3439 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
3440 pushed and popped by m4sugar, should be first on the stack.
3442 Provide warn, complain, and fatal function callbacks to the skeletons.
3443 This provides more flexibility than m4_fatal, improves the error
3444 message format, and captures messages for translation. Discussed
3446 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
3447 * data/bison.m4 (b4_error): New, invoked by...
3448 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
3449 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3450 directives. Because these M4 macros might be called when the current
3451 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3452 the previous removal of uses of m4_divert, which caused trouble.
3453 (b4_check_percent_code_qualifiers): Use b4_complain instead of
3454 m4_fatal to report unrecognized %code qualifiers.
3455 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
3456 push parser requests.
3457 * data/glr.c: Use b4_complain instead of m4_fatal to report
3458 non-deterministic push parser requests.
3459 Update @output usage to @output(...@) form.
3460 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
3461 report missing %defines. Update @output usage to @output(...@) form.
3462 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
3464 * src/main.c (main): Invoke skel_scanner_free.
3465 * src/scan-skel.h (skel_scanner_free): Prototype new function.
3466 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
3467 obstack_for_string from flex-scanner.h.
3468 (YY_DECL): Use to declare skel_lex static.
3469 (decode_at_digraphs): Remove; now handled in the new
3470 SC_AT_DIRECTIVE_ARG start condition.
3471 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
3473 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
3474 at_directive_argv): New static globals.
3475 (INITIAL): Use fail_for_invalid_at.
3476 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
3477 recognize the start of a generalized `@directive(...@)' form and
3479 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
3480 directive args (using the new obstack_for_string), to decode the
3481 contained @ diagraphs, and to perform the directive. It recognizes
3482 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
3484 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
3485 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
3487 (scan_skel): Initialize obstack_for_string on the first call.
3488 (skel_scanner_free): New function to free obstack_for_string.
3489 * tests/input.at (Reject bad %code qualifiers): Update test output.
3491 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
3493 Consolidate the 4 prologue alternative directives (%code, %requires,
3494 %provides, and %code-top) into a single %code directive with an
3495 optional qualifier field. Discussed at
3496 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
3497 * NEWS (2.3a+): Rewrite the existing entry for the prologue
3499 * doc/bison.texinfo (Prologue Alternatives): Update.
3500 (Decl Summary): Update to %code "requires" and %code "provides".
3501 (Calc++ Parser): Update to %code "requires".
3502 (Table of Symbols): Remove entries for %requires, %provides, and
3503 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
3504 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
3505 are replaced by b4_percent_code_provides and b4_percent_code_requires,
3506 which are skeleton-specific.
3507 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
3508 declare what %code qualifiers it supports and to complain if any other
3509 qualifiers were used in the grammar.
3510 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
3511 and b4_user_code([b4_percent_code_provides]) in place of
3512 b4_user_requires and b4_user_provides.
3513 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
3514 Add b4_user_code([b4_percent_code_top]) and
3515 b4_user_code([b4_percent_code]).
3516 Invoke b4_check_percent_code_qualifiers.
3517 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3518 PERCENT_REQUIRES): Remove.
3519 (grammar_declaration): Remove RHS's for %code-top, %provides, and
3520 %requires. Rewrite the %code RHS as the unqualified form defining the
3521 muscle b4_percent_code. Add another RHS for the qualified %code form,
3522 which defines muscles of the form b4_percent_code_QUALIFIER and the
3523 b4_used_percent_code_qualifiers muscle.
3524 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3525 PERCENT_REQUIRES): Remove.
3526 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
3527 %code "requires" and %code "provides".
3528 * tests/input.at (Reject bad %code qualifiers): New.
3530 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3532 Use the new code_props interface for destructors and printers.
3533 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
3534 printer_location members, and change the type of the destructor and
3535 printer members to code_props.
3536 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
3537 symbol_printer_get, semantic_type_destructor_set,
3538 semantic_type_printer_set, default_tagged_destructor_set,
3539 default_tagless_destructor_set, default_tagged_printer_set,
3540 default_tagless_printer_set): Use code_props in arguments and return
3541 types in place of char const * and location.
3542 (symbol_destructor_location_get, symbol_printer_location_get): Remove
3543 since the locations are now contained in the return of
3544 symbol_destructor_get and symbol_printer_get.
3545 * src/output.c (symbol_destructors_output, symbol_printers_output):
3547 (symbol_code_props_output): ... this to eliminate duplicate code.
3548 (output_skeleton): Update to use symbol_code_props_output.
3549 * src/reader.c (symbol_should_be_used): Update use of
3550 symbol_destructor_get.
3551 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3552 Update uses of the various _destructor_set and _printer_set functions.
3553 * src/symtab.c: (default_tagged_destructor_location,
3554 default_tagless_destructor_location, default_tagged_printer_location,
3555 default_tagless_printer_location): Remove since we...
3556 (default_tagged_destructor, default_tagless_destructor,
3557 default_tagged_printer, default_tagless_printer): ... change the type
3558 of these to code_props.
3559 (symbol_new, semantic_type_new, symbol_destructor_set,
3560 semantic_type_destructor_set, symbol_destructor_get,
3561 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
3562 symbol_check_alias_consistency, default_tagged_destructor_set,
3563 default_tagless_destructor_set, default_tagged_printer_set,
3564 default_tagless_printer_set): Update.
3565 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
3566 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
3568 (symbol_print): Use SYMBOL_CODE_PRINT.
3570 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3572 Use the new code_props interface for rule actions.
3573 * src/symlist.h (symbol_list): Replace action, action_location, and
3574 used members with a code_props action_props member.
3575 * src/reader.c (symbol_should_be_used, grammar_rule_check,
3576 grammar_midrule_action, grammar_current_rule_merge_set,
3577 grammar_current_rule_symbol_append, packgram): Update.
3578 * src/scan-code.h (translate_rule_action): Remove, no longer used.
3579 * src/scan-code.l (handle_action_dollar): Update.
3580 (translate_rule_action): Remove, no longer used.
3581 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
3583 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3585 Use the new code_props interface in parse-gram.y.
3586 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
3587 Update all uses of translate_* functions to use the new code_props
3588 interface and to use gram_scanner_last_string_free and
3589 code_scanner_last_string_free where possible.
3590 (grammar_declaration): symbol_list_destructor_set and
3591 symbol_list_printer_set now perform the translation, so don't do it
3592 here. Use gram_scanner_last_string_free where possible.
3593 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
3594 translate_code): Remove, no longer used.
3595 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
3596 symbol_list_printer_set): Perform code translation here rather than
3597 depending on the caller to do so.
3599 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3600 * src/scan-gram.h (gram_last_string): Remove declaration.
3601 * src/scan-gram.l (last_string): Declare it static.
3603 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3605 Encapsulate code properties and related functionality for the various
3606 destructors, printers, and actions into a code_props structure and
3607 interface. This patch merely implements code_props in scan-code.h and
3608 scan-code.l. Future patches will rewrite other modules to use it.
3609 Discussed starting at
3610 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3611 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3612 consistently initialize const structs that have an empty location
3614 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3615 to ensure consistency.
3616 * src/scan-code.h (code_props): New structure.
3617 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3618 function, macro, and const global variable for initializing a
3619 code_props with no code.
3620 (code_props_plain_init, code_props_symbol_action_init,
3621 code_props_rule_action_init, code_props_translate_code): The rest of
3622 the new code_props functional interface. Among other things, the init
3623 functions set the code_props kind field so that
3624 code_props_translate_code will know whether to behave like
3625 translate_symbol_action, translate_rule_action, or translate_code.
3626 These old translate functions must remain until all other modules are
3627 updated to use the new code_props interface.
3628 (code_scanner_last_string_free): New function similar to
3629 gram_scanner_last_string_free.
3630 (code_scanner_free): Add documentation.
3631 * src/scan-code.l: Implement the new interface.
3632 (code_lex): Make it static, add a code_props* argument, and remove the
3634 (last_string): New static global similar to the one in scan-gram.l.
3635 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3637 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3638 code_props since Bison may one day use this information for destructors
3640 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3641 (handle_action_dollar): Use symbol_list_n_get and set used flag
3642 directly since symbol_list_n_used_set is removed.
3643 (translate_action): Add a code_props* argument and remove the rule,
3644 action, and location arguments. Pass the code_props* on to code_lex.
3645 (translate_rule_action, translate_symbol_action, translate_code):
3646 Rewrite as wrappers around the new code_props interface.
3647 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3648 it would eventually need to break the encapsulation of code_props.
3650 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3652 * etc/.cvsignore: New.
3654 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3656 Add maintainer-push-check to run maintainer-check using push parsing in
3657 place of pull parsing where available.
3658 * Makefile.am (maintainer-push-check): New.
3659 * data/bison.m4 (b4_use_push_for_pull_if): New.
3660 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3661 appropriately based on their existing values.
3662 (yypush_parse): Don't print push-parser-specific diagnostics if push
3663 parsing is being used in place of pull parsing.
3664 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3666 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3667 variable, and insert b4_use_push_for_pull_flag into muscles.
3668 * tests/Makefile.am (maintainer-push-check): New.
3670 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3672 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3673 (whether successful or failed) so that yypush_parse can be invoked
3674 again to start a new parse using the same yypstate.
3675 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3676 check multiple yypull_parse invocations on the same yypstate. For pull
3677 mode, extend to check multiple yyparse invocations.
3678 (Exploding the Stack Size with Alloca): Extend to try with
3680 (Exploding the Stack Size with Malloc): Likewise.
3682 * tests/calc.at (Simple LALR Calculator): Don't specify
3683 %skeleton "push.c" since %push-pull-parser implies that now.
3684 * tests/headers.at (export YYLTYPE): Don't check for the push
3685 declarations. Otherwise, this test case can't be used to see if push
3686 mode can truly emulate pull mode.
3687 * tests/input.at (Torturing the Scanner): Likewise.
3688 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3689 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3690 AT_YACC_IF, which now includes the case of push mode since %skeleton
3691 need not be used for push mode. This will be more intuitive once
3692 push.c is renamed to yacc.c.
3694 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3696 For push mode, convert yyparse from a macro to a function, invoke yylex
3697 instead of passing a yylexp argument to yypull_parse, and don't
3698 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3699 Discussed starting at
3700 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3701 * data/bison.m4 (b4_pull_if): New.
3702 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3703 * data/push.c: Improve M4 quoting a little.
3704 (b4_generate_macro_args, b4_parenthesize): Remove.
3705 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3706 any time a pull parser is requested.
3707 Don't #define this as a wrapper around yypull_parse. Instead, when
3708 both push and pull are requested, make it a function that does that
3710 (yypull_parse): If there's a b4_prefix, #define this to
3711 b4_prefix[pull_parse] when both push and pull are requested.
3712 Don't define this as a function unless both push and pull are
3714 Remove the yylexp argument and hard-code yylex invocation instead.
3715 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3717 * src/getargs.c (pull_parser): New global initialized to true.
3718 * getargs.h (pull_parser): extern it.
3719 * src/output.c (prepare): Insert pull_flag muscle.
3720 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3721 (prologue_declaration): Set both push_parser and pull_parser = true for
3722 %push-pull-parser. Set push_parser = true and pull_parser = false for
3724 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3725 %push-parser since there's no backward-compatibility concern here.
3726 Scan %push-pull-parser.
3727 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3728 instead of %push-parser.
3729 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3730 prototype it in the module that calls yyparse.
3731 * tests/input.at (Torturing the Scanner): Likewise.
3732 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3734 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3736 Update etc/bench.pl. Optimize push mode a little (the yyn change
3737 deserves most of the credit).
3738 * Makefile.am (SUBDIRS): Add etc subdirectory.
3739 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3740 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3741 yytoken, yyval, and yyloc declarations to...
3742 (yyparse or yypush_parse): ... here to improve performance. For
3743 yypush_parse invocations after the first, be sure to assign yyn its old
3745 (yypstate_new): Don't bother initializing the yyresult field since the
3746 initial value isn't used.
3747 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3748 remove the #define that, in push mode, set it to yyps->NAME.
3749 * etc/Makefile.am: New.
3750 * etc/bench.pl: Remove and build it instead from...
3751 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3752 "tests/bison" from the build directory by default rather than just
3753 invoking "bison" from $PATH.
3754 (calc_grammar): Update push parser code: don't declare yylval globally,
3755 don't define yyparse_wrapper, and don't #define yyparse.
3756 (bench_grammar): Update to check all working combinations of yacc.c,
3757 push.c, impure, pure, pull, and push.
3759 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3761 For push mode, add pull wrappers around yypush_parse.
3762 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3763 (yypull_parse): New function wrapping yypush_parse.
3764 (yyparse): New #define wrapping yypull_parse.
3765 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3767 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3768 prototype yylex in the module that calls yyparse, and don't prototype
3769 yyparse there. Otherwise, the yyparse expansion won't compile.
3770 * tests/input.at (Torturing the Scanner): Likewise.
3772 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3774 Enable push parsers to operate in impure mode. Thus, %push-parser no
3775 longer implies %pure-parser. The point of this change is to move
3776 towards being able to test the push parser code by running the entire
3777 test suite as if %push-parser had been declared.
3778 * data/push.c (yypush_parse): For impure mode, remove the
3779 yypushed_char, yypushed_val, and yypushed_loc arguments.
3780 Instead, declare these as local variables initialized to the global
3781 yychar, yylval, and yylloc.
3782 For the first yypush_parse invocation only, restore the initial values
3783 of these global variables when it's time to read a token since they
3784 have been overwritten.
3785 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3787 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3788 %pure-parser along with %push-parser since this test case was designed
3789 for pure push parsers.
3790 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3791 (AT_YACC_OR_PUSH_IF): New.
3792 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3793 add a note that it's still wrong for some cases (as it has been for a
3795 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3796 %push-parser no longer implies %pure-parser.
3798 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3800 Remove some unnecessary differences between the pull parser code and
3801 the push parser code. This patch enables yynerrs in push mode.
3802 * data/push.c: Reformat M4 a little.
3803 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3804 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3805 because push mode is on. Instead, if pure mode is on, move yynerrs
3807 (b4_declare_parser_state_variables): ... here.
3808 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3809 to yyps->NAME so it can be used in yypush_parse.
3810 (yypush_parse): Don't omit uses of yynerrs in push mode.
3812 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3814 Fix bug such that the first pushed token's value and location are
3815 sometimes overwritten (sometimes by %initial-action) before being used.
3816 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3817 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3818 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3819 more closely mimic the pull parser logic.
3820 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3821 time to read a token, which is after any initialization of yylval and
3823 (gottoken): Rename label to...
3824 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3827 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3829 Rearrange initialization of the parser state variables so that the
3830 skeleton doesn't have to have a copy for pull mode and another for push
3831 mode. This patch also fixes at least a bug such that yylloc was not
3832 initialized (with b4_location_initial_line and
3833 b4_location_initial_column) upon calling yypush_parse. However, that
3834 initialization now overwrites the first token's location;
3835 %initial-action assigning @$ already did the same thing, and both bugs
3836 will be fixed in a later patch.
3837 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3838 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3839 yyss, yyvs, yyls, and yystacksize.
3840 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3841 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3843 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3844 yyps->NAME so it can be used in yypush_parse.
3845 (yyparse or yypush_parse): For yypush_parse, don't print the
3846 "Starting parse" diagnostic for invocations after the first.
3847 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3848 yypush_parse, only do it for the first invocation.
3849 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3850 initialization to occur in yypush_parse but only on the first
3853 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3855 * data/push.c: Add CPP guards around push parser declarations in both
3856 the header and the code file.
3857 In the code file, move the push parser declarations to the same place
3858 they appear in the header file.
3859 Clean up the M4 some, especially the inconsistent underquoting in
3860 some b4_c_function_def and b4_c_function_decl uses.
3862 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3864 Encapsulate the push parser state variables into an M4 macro so the
3865 push skeleton doesn't have to list them again for pull mode's yyparse.
3866 For push mode, remove yypush_parse's local equivalents of these
3867 variables to eliminate unnecessary copying between the two sets at
3868 run-time. This patch also fixes at least a bug related to multiple
3869 %initial-action invocations in push mode.
3870 * data/push.c (b4_declare_parser_variables): Rename to...
3871 (b4_declare_scanner_communication_variables): ... this for clarity and
3873 (b4_declare_yyparse_variables): Remove and move its contents to the one
3874 spot where it was invoked.
3875 (b4_declare_parser_state_variables): New macro containing the parser
3876 state variables required by push mode.
3877 (struct yypstate): Replace all fields but yynew with
3878 b4_declare_parser_state_variables.
3879 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3880 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3881 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3882 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3883 parser state variable declarations with
3884 b4_declare_parser_state_variables.
3885 Don't initialize parser state variables when calling yypush_parse since
3886 yypstate_new already does that.
3887 Invoke the user's initial action only upon the first yypush_parse
3889 Remove all code that copies between the local parser state variables
3892 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3894 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3895 prevent a name collision in a future patch where these names will
3896 sometimes be #define'd.
3897 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3898 since it no longer has the same name as the existing argument.
3899 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3901 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3902 and Joel E. Denny <jdenny@ces.clemson.edu>
3904 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3905 that the argument is case-insensitive, and there's no `=' here.
3906 For the %skeleton entry, mention that %language is better.
3907 (Bison Options): Likewise for --language and --skeleton. Move the
3908 --skeleton entry so that the `Tuning the parser' section is sorted
3909 alphabetically on long options.
3910 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3911 %language directive in detail here; cross-reference the %language
3912 documentation instead.
3913 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3914 `%require "2.3b"' so that the example is always up-to-date.
3915 (Table of Symbols): Add entries for %language and %skeleton.
3916 * examples/extexi (normalize): Instead of replacing every %require
3917 argument with the current Bison version, just substitute for
3918 `@value{VERSION}'. This guarantees that we're testing what actually
3919 appears in the documentation.
3920 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3921 rather than `@VERSION@'.
3923 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3925 * NEWS: Reword the %language news a bit, and put it earlier.
3927 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3928 Rewrite to simplify the logic.
3929 (language_argmatch): Likewise.
3930 (program_name): We now own this var.
3931 * src/getargs.h (struct bison_language): Use char[] rather than
3934 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3936 * src/complain.c (program_name): Remove decl; no longer needed.
3937 * src/main.c (program_name): Remove; now belongs to getargs.
3939 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3941 * NEWS: Document %language.
3943 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3945 * data/c-skel.m4, data/c++-skel.m4: New files.
3946 * data/glr.c: Complain on push parsers.
3948 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3950 (Decl Summary): Document %language and %skeleton.
3951 (Command line): Document -L.
3953 * examples/extexi: Rewrite %require directive.
3954 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3956 * src/files.c (compute_exts_from_gc): Look in language structure
3958 (compute_file_name_parts): Check whether .tab should be added.
3959 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3960 (language, skeleton_arg, language_argmatch): New.
3961 (long_options): Add --language.
3962 (getargs): Use skeleton_arg, add -L/--language.
3963 * src/getargs.h: Include location.h.
3964 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3965 * src/output.c (prepare): Pick default skeleton from struct language.
3966 Don't dispatch C skeletons here.
3967 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3968 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3969 * src/scan-gram.l ("%language"): New rule.
3971 * tests/calc.at: Test %skeleton and %language.
3972 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3973 (AT_GLR_IF): Look for %skeleton "glr.cc".
3974 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3975 (AT_YACC_IF): Reject %language.
3977 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3979 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3980 since it wasn't used; only the typedef name 'semantic_type' is needed.
3981 Also, omit trailing white space.
3983 * bootstrap: Sync from coreutils.
3984 (gnulib_extra_files): Add build-aux/announce.gen.
3985 (slurp): Adjust .gitignore files like .cvsignore files.
3986 * build-aux/announce-gen: Remove from CVS, since bootstrap
3989 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3991 Make %push-parser imply %pure-parser. This fixes several bugs; see
3992 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3993 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3995 * data/push.c: Don't bother testing b4_push_if when deciding whether
3996 to expand b4_declare_parser_variables globally.
3997 (yypush_parse): Likewise in here.
3999 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
4000 (yy_reduce_print): Reformat M4 for readability.
4002 2006-12-15 Bob Rossi <bob@brasko.net>
4003 and Joel Denny <jdenny@ces.clemson.edu>
4005 * data/push.c (yypstate): Add typedef, and update all uses of
4006 struct yypstate to just yypstate.
4007 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
4009 2006-12-14 Bob Rossi <bob@brasko.net>
4011 * data/push.c (yypush_parse): Declare prototype regardless of
4014 2006-12-14 Bob Rossi <bob@brasko.net>
4016 * data/push.c (yyparse): Remove the prototype and the #define when in
4019 2006-12-13 Bob Rossi <bob@brasko.net>
4021 * data/push.c (yypstate_init): Rename to...
4022 (yypstate_new): ... this and use b4_c_function_def.
4023 (yypstate_delete): New.
4024 (yypush_parse): Change parameters yynval and yynlloc to be const.
4025 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4026 yypstate_delete functions.
4028 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4030 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4031 strange test case titles. Reported by Bob Rossi.
4033 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4035 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4036 of potential ambiguities in GLR grammers.
4038 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4040 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4041 `bison ', use m4_index instead of m4_substr since chopping up a string
4042 containing M4-special characters causes problems here.
4044 Fix a couple of bugs related to special characters in user-specified
4045 file names, and make it easier for skeletons to compute output file
4046 names with the same file name prefix as Bison-computed output file
4048 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4049 b4_parser_file_name and b4_spec_defines_file instead of
4050 @output_parser_name@ and @output_header_name@, which are now redundant.
4051 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4052 b4_parser_file_name, b4_spec_defines_file, and the new
4053 @basename(FILENAME@) instead of @output_parser_name@ and
4054 @output_header_name@, which inappropriately escaped the file names as
4056 * src/files.c (all_but_ext): Remove static qualifier.
4057 (compute_output_file_names): Move `free (all_but_ext)' to...
4058 (output_file_names_free): ... here since all_but_ext is needed later.
4059 * src/files.h (all_but_ext): Extern.
4060 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4061 exactly what MUSCLE_INSERT_STRING used to do.
4062 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4063 characters are escaped properly.
4064 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4066 For pkgdatadir muscle, maintain previous functionality by using
4067 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4068 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4069 digraphs would never be expanded. Hopefully no one has M4-special
4070 characters in his Bison installation path.
4071 * src/scan-skel.l: Don't parse @output_header_name@ and
4072 @output_parser_name@ anymore since they're now redundant.
4073 In @output, use decode_at_digraphs.
4074 Parse a new @basename command that invokes last_component.
4075 (decode_at_digraphs): New.
4076 (BASE_QPUTS): Remove unused.
4077 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4078 (Output file name): New tests.
4080 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
4082 Warn about output files that are generated by the skeletons and that
4083 conflict with other output files.
4084 * data/glr.c: Don't generate the header file here when glr.cc does.
4085 * src/files.c (file_names, file_names_count): New static globals.
4086 (compute_output_file_names): Invoke output_file_name_check for files
4087 not generated by the skeletons and remove existing checks.
4088 (output_file_name_check): New function that warns about conflicting
4090 (output_file_names_free): Free file_names.
4091 * src/files.h (output_file_name_check): Declare.
4092 * src/scan-skel.l: Invoke output_file_name_check for files generated by
4094 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
4095 (Conflicting output files): New tests.
4097 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4099 * doc/bison.texinfo: Fix a couple of typos.
4101 2006-12-08 Bob Rossi <bob@brasko.net>
4103 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
4105 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
4107 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
4108 (yypush_parse): Rename yypvars argument to yyps and remove redundant
4110 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
4111 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
4113 2006-12-07 Bob Rossi <bob@brasko.net>
4114 and Joel Denny <jdenny@ces.clemson.edu>
4116 * data/push.c (yypvarsinit): Change return type from void* to struct
4117 yypvars*. No longer cast to void* on return.
4118 (struct yypvars): Remove yylen since it need not be remembered between
4119 yypushparse invocations.
4120 (yypushparse): Don't copy between yylen and pv->yylen.
4122 2006-12-05 Bob Rossi <bob@brasko.net>
4124 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
4125 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
4126 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
4127 (struct yypvars): Remove b4_declare_parser_variables.
4128 (yypvarsinit): Remove init code for removed variables.
4129 (global scope): Do not declare b4_declare_parser_variables if
4131 (yypushparse): Add b4_declare_parser_variables.
4132 Init new local variables, and remove init code for removed
4135 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
4136 and yyparse for other modes.
4137 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
4138 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
4139 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
4140 (AT_PURE_LEX_IF): True if pure or push parser.
4142 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

4237 * src/files.c (tr): Change return type to void.
4238 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
4239 has been called previously for the same key.
4240 (muscle_find): Return storage instead of value so that
4241 --enable-gcc-warnings doesn't produce warnings that the return discards
4242 const. aver that the value and storage are the same since storage
4243 could potentially be NULL when value is not.
4244 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4247 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4249 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4250 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4251 us a slightly cleaner distribution, and also works.
4252 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4255 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4256 and Paul Eggert <eggert@cs.ucla.edu>
4258 Don't let Bison leak memory except when it complains.
4259 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
4260 (spec_defines_file, dir_prefix): Now char *, not const char *,
4261 since they are freed.
4262 * src/files.c: Likewise.
4263 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4265 (tr): Now operates in-place. All uses changed.
4266 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
4268 (compute_file_name_parts, compute_output_file_names): Don't store
4269 read-only data in variables that will be freed.
4270 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4271 src_extension, and header_extension.
4272 (output_file_names_free): New public function to free
4273 spec_verbose_file, spec_graph_file, spec_defines_file,
4274 parser_file_name, and dir_prefix.
4275 * src/getargs.c (getargs): Don't store read-only data in variables that
4277 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4278 (which previously existed but was unused), and quotearg_free.
4279 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4280 * src/muscle_tab.c: Likewise.
4281 (muscle_entry): Make the value char const *,
4282 and add a new storage member that is char * and can be freed.
4283 (muscle_entry_free): New private function.
4284 (muscle_init): Use it instead of free.
4285 (muscle_insert, muscle_grow): Update and use new storage member.
4286 (muscle_code_grow): Free the string passed to muscle_grow
4287 since it's not needed anymore.
4288 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4289 add a new `char *code' member.
4290 ("{...}"): Declare semantic type as code.
4291 * src/scan-code.h (translate_rule_action):
4292 (translate_symbol_action, translate_code, translate_action): Return
4293 `char const *' rather than `char *' since external code should not free
4295 * src/scan-code.l: Likewise.
4296 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4297 which is "{...}" in the parser.
4298 * tests/Makefile.am (maintainer-check-valgrind): Set
4299 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4301 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4303 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4304 expecting a non-zero exit status sets --leak-check=summary and
4305 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4306 this case, and we don't want to hear about it.
4308 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4310 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4311 instead of from the template, to simplify configuration a bit.
4312 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
4313 and m4/wint_t.m4, as they are needed with the latest gnulib.

4324 the value is a set/used mid-rule value unless
4325 --warnings=midrule-values was specified.
4326 * tests/input.at (Unused values, Unused values before symbol
4327 declarations): Run tests with and without --warnings=midrule-values.
4329 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4330 than LIST_FREE directly.
4332 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

4351 empty subargument list. For example: `bison --warnings= parser.y'.
4353 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4355 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
4356 the parser header file so that gcc doesn't warn.
4358 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4360 Split the default %destructor/%printer into two kinds: <*> and <!>.

4406 Don't apply the default %destructor/%printer to an unreferenced midrule
4408 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4409 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4410 like $@n instead of just @n so that the default %destructor/%printer
4411 logic doesn't see them as user-defined symbols.
4412 (symbol_is_dummy): Check for both forms of the name.
4413 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4414 name for which the midrule value is referenced in any action.
4415 * tests/actions.at (Default %printer and %destructor for mid-rule

4425 (packgram): Before invoking grammar_rule_check on any rule, make sure
4426 all actions have already been scanned in order to set `used' flags.
4427 Otherwise, checking that a midrule's $$ is set will not always work
4428 properly because the midrule check must forward-reference the midrule's

4440 to show how these directives may be viewed as code labels.
4442 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
4444 Similar to the recently removed %before-header, add %code-top as the
4445 alternative to the pre-prologue. Mentioned at
4446 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

4512 Fix testsuite for ./configure --enable-gcc-warnings:
4513 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.

4550 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
4551 Include <config.h> unconditionally.
4553 * bootstrap: Sync from coreutils, as follows:
4555 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4557 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
4558 variable was sometimes used without being initialized. This
4559 messed up the installation of the INSTALL file in some cases.
4561 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4563 * bootstrap (usage, main program, symlink_to_gnulib): Add option
4564 --copy. Inspired by a suggestion from Bruno Haible.
4566 2006-10-03 Jim Meyering <jim@meyering.net>
4568 * bootstrap: Undo last change to this file, since now gnulib-tool
4569 sticks with the automake default in generating dependencies.
4571 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4573 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

4664 Fix problems with translating English-language diagnostics.
4665 * bootstrap: Fix bug introduced in recent bootstrap changes, with
4666 respect to bison-runtime pot generation. The YY_ stuff
4667 wasn't being captured.
4668 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
4669 * po/POTFILES.in: Add src/location.c, src/scan-code.l.

4674 Merge bootstrap changes from coreutils.
4676 2006-09-28 Jim Meyering <jim@meyering.net>
4678 Automatically generated dependencies are important even
4679 when all of the sources in a directory come from gnulib.
4680 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
4681 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
4683 2006-09-23 Jim Meyering <jim@meyering.net>

4691 (CVS_only_file): New var.
4693 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
4695 * data/push.c (YYPUSH_MORE): Make it an enum instead.
4696 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
4697 Adjust white space and comments to match GNU style better.
4699 2006-09-20 Bob Rossi <bob@brasko.net>
4701 * data/push.c (yyresult_get): Remove function.
4702 (YYPUSH_MORE): Add #define.
4703 (yypushparse): Modify return value.
4705 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4707 * stamp-h.in: Remove; no longer needed.
4708 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
4709 Remove config.h, config.hin, intl (no longer created).
4710 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
4713 Sync bootstrap from coreutils, as follows:
4715 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
4717 * bootstrap (symlink_to_gnulib): New function.
4718 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
4719 to copies-of-gnulib.
4720 (cp_mark_as_generated, slurp, gnulib_files):
4721 Avoid making a copy if it's the same as the old version.
4722 (gnulib_files): Add support for this variable (used by Bison).
4724 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4726 * src/getargs.c (usage): Rework to use conventions similar to
4727 coreutils, to make translation a bit easier and the code a bit
4728 smaller. Problem reported by Tim Van Holder.
4730 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4732 Use some of gnulib's new modules, taken from coreutils.
4734 * bootstrap: Sync from coreutils, except add support for gnulib_files.
4735 * bootstrap.conf: New file.
4736 (gnulib_modules): Add configmake, inttypes, unistd.
4737 (XGETTEXT_OPTIONS): Add complain, complain_at,
4738 fatal, fatal_at, warn, warn_at, unexpected_end.
4739 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
4740 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
4742 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4744 (GNULIB_AUTOCONF_SNIPPET): Remove.
4745 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4747 * lib/.cvsignore: Add inttypes_.h.
4748 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4749 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4750 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4751 no-longer-necessary initializations.
4752 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
4753 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4754 use the unistd module.
4755 * src/system.h: Likewise.
4756 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4757 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4758 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4759 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4760 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4761 * src/system.h: Include inttypes.h unconditionally, now that we
4762 use the inttypes module. Don't bother to include stdint.h, since
4763 inttypes.h now does that for us.
4764 (LOCALEDIR): Remove, now that we use the configmake module.
4765 * src/getargs.c: Include configmake.h.
4766 * src/main.c: Likewise.
4767 * src/output.c: Likewise.
4768 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4769 not from $abs_top_builddir, since config.h moved.
4772 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4773 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4775 * src/parse-gram.y (symbol_declaration): Don't put statements
4776 before declarations; it's not portable to C89.
4777 * src/scan-code.l (handle_action_at): Likewise.
4779 * src/scan-code.l: Always initialize braces_level; the old code
4780 left it uninitialized and therefore had undefined behavior.
4782 Don't attempt to redefine 'assert', since it runs afoul of
4783 systems where standard headers (mistakenly) include <assert.h>.
4784 Instead, define and use our own alternative, called 'aver'.
4785 * src/reader.c: Don't include assert.h, since we no longer
4787 * src/scan-code.l: Likewise.
4788 * src/system.h (assert): Remove, replacing with....
4789 (aver): New function, taking a bool arg. All uses changed.
4790 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4791 not merely an integer.
4793 2006-09-15 Bob Rossi <bob@brasko.net>
4795 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4796 * data/c.m4 (YYPUSH): New.
4797 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4798 * src/getargs.c (push_parser): New var.
4799 * src/getargs.h (push_parser): New declaration.
4800 * src/output.c (prepare): Add macro insertion of `push_flag'.
4801 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4802 (prologue_declaration): Parse %push-parser.
4803 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4804 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4805 list of removed lines from the traces observed.
4806 (AT_CHECK_CALC_LALR): Added push parser tests.
4808 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4810 * NEWS: Version 2.3a.
4811 * configure.ac (AC_INIT): Likewise.
4813 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4814 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4815 due to header ordering dependencies. I don't know why the #define
4818 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4819 runtime cost when YYDEBUG is not defined, and so that some tests
4820 that used to fail now work. Problem and initial suggestion by
4822 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4823 * data/glr.cc (b4_parser_class_name):
4824 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4825 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4826 (yydebug_) [YYDEBUG]: New member.
4827 (yycdebug_): Now defined only if YYDEBUG.
4828 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4829 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4830 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4832 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4833 Define only if YYDEBUG.
4834 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4836 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4837 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4838 AT_CHECK_CALC_GLR_CC that are working now.
4840 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4842 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4843 We don't need them in glr.cc, and glr.c defines them.
4844 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4845 assumes that defining it to anything is the same as defining
4846 it to 1. Problem reported by Paolo Bonzini.
4848 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4850 * data/c.m4 (b4_null, b4_case): Define.
4851 * src/output.c (prepare_symbols): Use b4_null.
4852 (user_actions_output): Use b4_case.
4854 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4856 * data/glr.c (b4_shared_declarations): Put start-header first,
4857 before any #includes that we generate, so that feature-test
4858 macros work. Problem reported by Michael Deutschmann in
4859 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4860 * data/lalr1.cc: Likewise.
4861 * doc/bison.texinfo (Prologue): Document that feature-test macros
4862 should be defined before any Bison declarations.
4863 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4864 that depend on location.hh after, not before, Bison decls, since
4865 we now include location.hh after the first user prologue.
4867 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4868 Sander Brandenburg in
4869 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4870 Also, fix minor white space and comment issues.
4871 (Prologue): Mention that it's better to define feature-test macros
4872 before Bison declarations. Problem reported by Michael Deutschmann.
4874 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4876 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4877 This adjusts to recent gnulib changes.
4879 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4881 Finish implementation of per-type %destructor/%printer. Discussed
4883 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4885 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4886 * NEWS (2.3+): Add a description of this feature to the default
4887 %destructor/%printer description.
4888 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4889 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4890 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4891 list node contains a semantic type.
4892 * src/symtab.c, src/symtab.h: Extend with a table that associates
4893 semantic types with their %destructor's and %printer's.
4894 (semantic_type_from_uniqstr, semantic_type_get,
4895 semantic_type_destructor_set, semantic_type_printer_set): New functions
4896 composing the public interface of that table.
4897 (symbol_destructor_get, symbol_destructor_location_get,
4898 symbol_printer_get, symbol_printer_location_get): If there's no
4899 per-symbol %destructor/%printer, look up the per-type before trying
4901 * tests/actions.at (Per-type %printer and %destructor): New test case.
4902 * tests/input.at (Default %printer and %destructor redeclared):
4903 Extend to check that multiple occurrences of %symbol-default in a
4904 single %destructor/%printer declaration is an error.
4905 (Per-type %printer and %destructor redeclared, Unused values with
4906 per-type %destructor): New test cases.
4908 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4910 Require default %destructor/%printer to be declared using
4911 %symbol-default instead of an empty symbol list, and start working on
4912 new per-type %destructor/%printer. Discussed at
4913 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4914 * NEWS (2.3+): Add %symbol-default to example.
4915 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4916 (Table of Symbols): Add entry for %symbol-default.
4917 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4918 (generic_symlist, generic_symlist_item): New nonterminals for creating
4919 a list in which each item is a symbol, semantic type, or
4921 (grammar_declaration): Use generic_symlist in %destructor and %printer
4922 declarations instead of symbols.1 or an empty list.
4923 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4924 for changes to symbol_list.
4925 * src/reader.c: Update for changes to symbol_list.
4926 * src/scan-code.l: Likewise.
4927 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4928 * src/symlist.c, src/symlist.h: Extend such that a list node may
4929 represent a semantic type or a %symbol-default in addition to just an
4930 ordinary symbol. Add switched functions for setting %destructor's and
4932 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4933 %destructor/%printer declarations.
4935 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4937 Whether the default %destructor/%printer applies to a particular symbol
4938 isn't a question of whether the user *declares* that symbol (in %token,
4939 for example). It's a question of whether the user by any means
4940 *defines* the symbol at all (by simply using a char token, for
4941 example). $end is defined by Bison whereas any other token with token
4942 number 0 is defined by the user. The error token is always defined by
4943 Bison regardless of whether the user declares it with %token, but we
4944 may one day let the user define error as a nonterminal instead.
4945 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4946 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4947 the meaning of "user-defined".
4948 * tests/actions.at (Default %printer and %destructor for user-declared
4949 end token): Rename to...
4950 (Default %printer and %destructor for user-defined end token): ...
4953 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4954 computation of whether to apply the default, don't maintain a list of
4955 every Bison-defined symbol. Instead, just check for a first character
4956 of '$', which a user symbol cannot have, and check for the error token.
4958 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4960 Don't apply the default %destructor or %printer to the error token,
4961 $undefined, or $accept. This change fits the general rule that the
4962 default %destructor and %printer are only for user-declared symbols,
4963 and it solves several difficulties that are described in the new test
4965 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4966 * tests/actions.at (Default %printer and %destructor are not for error
4967 or $undefined, Default %printer and %destructor are not for $accept):
4970 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4972 Allow %start after the first rule.
4973 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4974 when parsing the first rule.
4975 (check_and_convert_grammar): Search for it here after all grammar
4976 declarations have been parsed. Skip midrules, which have dummy LHS
4978 * src/symtab.c (symbol_is_dummy): New function.
4979 * src/symtab.h (symbol_is_dummy): Declare it.
4980 * tests/input.at (%start after first rule): New test.
4982 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4984 Redo some of the previous commit: add back the ability to use
4985 non-aliased/undeclared string literals since it might be useful to
4986 those declaring %token-table.
4987 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4988 commit: don't worry about complaints from symbols_pack.
4989 * src/symtab.c (symbol_new, symbol_class_set,
4990 symbol_check_alias_consistency): Undo changes in previous commit: count
4991 each string literal as a new symbol and token, assign it a symbol
4992 number, and don't complain about non-aliased string literals.
4993 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4994 and token counts but does still set aliased tokens to the same number,
4995 symbol_pack_processor now leaves empty slots in the symbols array.
4997 * tests/regression.at (Undeclared string literal): Remove test case
4998 added in previous commit since non-aliased string literals are allowed
5000 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
5001 remove unnecessary string literal declarations.
5002 * tests/sets.at (Firsts): Likewise.
5004 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5006 Don't allow an undeclared string literal, but allow a string literal to
5007 be used before its declaration.
5008 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
5009 symbols_pack complained.
5010 * src/symtab.c (symbol_new): Don't count a string literal as a new
5012 (symbol_class_set): Don't count a string literal as a new token, and
5013 don't assign it a symbol number since symbol_make_alias does that.
5014 (symbol_make_alias): It's not necessary to decrement the symbol and
5015 token counts anymore. Don't assume that an alias declaration occurs
5016 before any uses of the identifier or string, and thus don't assert that
5017 one of them has the highest symbol number so far.
5018 (symbol_check_alias_consistency): Complain if there's a string literal
5019 that wasn't declared as an alias.
5020 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5021 symbol_pack asserts that every token has been assigned a symbol number
5022 although undeclared string literals have not.
5023 * tests/regression.at (String alias declared after use, Undeclared
5024 string literal): New test cases.
5025 (Characters Escapes, Web2c Actions): Declare string literals as
5027 * tests/sets.at (Firsts): Likewise.
5029 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5031 In the grammar scanner, STRING_FINISH unclosed constructs and return
5032 them to the parser in order to improve error messages.
5033 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5034 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5035 * tests/input.at (Unclosed constructs): New test case.
5036 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5039 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5042 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5044 Handle string aliases for character tokens correctly.
5045 * src/symtab.c (symbol_user_token_number_set): If the token has an
5046 alias, check and set its alias's user token number instead of its own,
5047 which is set to indicate the alias. Previously, every occurrence of
5048 the character token in the grammar overwrote that alias indicator with
5050 * tests/input.at (String aliases for character tokens): New test.
5052 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5054 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5056 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5058 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5059 to prevent failures when building on older platforms.
5060 Check for autopoint failure.
5061 Set XGETTEXT_OPTIONS to values that check for C format strings,
5062 so that translators are warned about them (this also helps
5063 prevent core dumps).
5065 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5066 function, since it simplifies our code a bit.
5068 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5069 rather than -W, so we don't get bogus warnings about sign comparisons.
5070 Add -Wpointer-arith, since that warning is useful (it reports code
5071 that does not conform to C89 and that some compilers reject).
5072 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5073 since it's no longer needed.
5075 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5077 Clean up scanners a bit.
5078 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5079 definitions so gcc won't warn when obstack_for_string is unused.
5080 * src/scan-code.l: config.h and system.h are already #include'd by
5081 scan-code-c.c, so get rid of them here.
5082 * src/scan-gram.l: Likewise.
5083 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
5084 definitions rather than duplicating the rest of it.
5085 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
5087 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
5089 Suppress signed/unsigned comparison warnings for yycheck.
5090 * data/c.m4 (b4_safest_int_type): New macro.
5091 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
5092 a signed int type, cast it to b4_safest_int_type first.
5093 * data/yacc.c: Likewise.
5094 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
5097 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
5099 * doc/bison.texinfo: Fix some typos.
5101 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
5103 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
5104 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
5106 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
5107 the latest gnulib does this a different way.
5108 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
5109 translation was patched, so stop omitting it.
5111 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5113 Enable declaration of default %printer/%destructor. Make the parser
5114 use these for all user-declared grammar symbols for which the user does
5115 not declare a specific %printer/%destructor. Thus, the parser uses it
5116 for token 0 if the user declares it but not if Bison generates it as
5117 $end. Discussed starting at
5118 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
5119 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
5121 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
5122 * NEWS (2.3+): Mention.
5123 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
5124 declare a %destructor for a mid-rule's semantic value. It's just
5125 impossible to declare one specific to it.
5126 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
5127 code. Describe default %destructor form.
5128 * src/parse-gram.y (grammar_declaration): Parse default
5129 %printer/%destructor declarations.
5130 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
5131 and symbol_destructor_location_get rather than accessing the destructor
5132 and destructor_location members of struct symbol.
5133 (symbol_printers_output): Likewise but for %printer's.
5134 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
5136 * src/symtab.c (default_destructor, default_destructor_location,
5137 default_printer, default_printer_location): New static global
5138 variables to record the default %destructor and %printer.
5139 (symbol_destructor_get, symbol_destructor_location_get,
5140 symbol_printer_get, symbol_printer_location_get): New functions to
5141 compute the appropriate %destructor and %printer for a symbol.
5142 (default_destructor_set, default_printer_set): New functions to set the
5143 default %destructor and %printer.
5144 * src/symtab.h: Prototype all those new functions.
5145 * tests/actions.at (Default %printer and %destructor): New test to
5146 check that the right %printer and %destructor are called, that they're
5147 not called for $end, and that $$ and @$ work correctly.
5148 (Default %printer and %destructor for user-declared end token): New
5149 test to check that the default %printer and %destructor are called for
5150 a user-declared end token.
5151 * tests/input.at (Default %printer and %destructor redeclared, Unused
5152 values with default %destructor): New tests to check related grammar
5153 warnings and errors.
5155 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5157 Clean up handling of %destructor for the end token (token 0).
5158 Discussed starting at
5159 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
5161 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
5163 Make the skeletons consistent in how they pop the end token and invoke
5165 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
5166 state, which has token number 0, since this would invoke the
5167 %destructor for the end token.
5168 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
5169 until after shifting the end token, or else it won't be popped.
5170 * data/yacc.c (yyparse): Likewise.
5172 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
5173 it's the end token. Upon termination, destroy an unshifted lookahead
5174 even when it's the end token.
5175 * data/lalr1.cc (yy::parser::parse): Likewise.
5176 * data/yacc.c (yyparse): Likewise.
5178 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
5179 value warnings for the end token when the user gives the end token a
5182 * tests/actions.at (Printers and Destructors): Test all the above.
5184 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5186 Update to latest gnulib and gettext versions.
5187 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
5189 (gnulib_files): Add m4/warning.m4. Don't worry about files
5190 overwritten by autopoint.
5191 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
5192 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5194 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5195 so that we can remove the intl files at a better time.
5196 (intl_files_to_remove): Remove aclocal.m4, since it gets
5197 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5198 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5199 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5200 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5201 Remove datarootdir hack; no longer needed.
5202 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5203 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5204 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5206 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5207 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5209 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5211 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5212 it with --assume-autoconf='latest-stable'.
5214 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5216 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5217 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5219 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5220 those from muscle_tab.c since the old ones are misleading.
5222 2006-07-13 Akim Demaille <akim@epita.fr>
5224 Support %define "KEY" {VALUE}.
5225 * src/scan-code.h, src/scan-code.l (translate_action)
5226 (translate_rule_action, translate_symbol_action, translate_code):
5227 Return char *, not const char *.
5228 * src/parse-gram.y (declaration): Rename as...
5229 (prologue_declaration): this.
5230 (string_content): Remove this nonterminal, use STRING.
5231 (braceless, content, content.opt): New nonterminal.
5233 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5235 * src/scan-gram.l (getargs.h): Don't include it.
5237 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5239 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5240 rather than a for-loop that declares a local bool variable. This
5241 should work around a compatibility problem with a Cray x1e C++
5242 compiler reported by Hung Nguyen in
5243 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5244 The for-loop was introduced in the 2004-11-17 change but I don't
5245 know why it was needed.
5247 2006-07-12 Akim Demaille <akim@epita.fr>
5249 * data/c.m4: Comment changes.
5251 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5253 * src/complain.c (error_message, ERROR_MESSAGE): New.
5255 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5256 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5258 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5260 * NEWS: Instead of %union, you can define and use your own union type
5261 YYSTYPE if your grammar contains at least one <type> tag.
5262 Your YYSTYPE need not be a macro; it can be a typedef.
5263 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5264 (Union Decl, Decl Summary): Document this.
5265 * data/glr.c (YYSTYPE): Implement this.
5266 * data/glr.cc (YYSTYPE): Likewise.
5267 * data/lalr1.cc (YYSTYPE): Likewise.
5268 * data/yacc.c (YYSTYPE): Likewise.
5269 * src/output.c (prepare): Output tag_seen_flag.
5270 * src/parse-gram.y (declaration, grammar_declaration):
5271 Use 'union_seen' rather than 'typed' to determine whether
5272 %union has been seen, since grammars can now be typed without
5274 (symbol_declaration, type.opt, symbol_def):
5275 Keep track of whether a tag has been seen.
5276 * src/reader.c (union_seen, tag_seen): New vars.
5278 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5279 * src/scan-code.l (untyped_var_seen): New variable.
5280 (handle_action_dollar): Adjust to above changes.
5281 (handle_action_dollar, handle_action_at):
5282 Improve overflow checking for outlandish numbers.
5283 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5284 avoid new diagnostics generated by above changes.
5285 * tests/regression.at (YYSTYPE typedef): Add test to check
5286 for type tags without %union.
5288 * src/symlist.c (symbol_list_length): Return int, not unsigned
5289 int, since callers expect int. This may need to get revisited
5290 once we have proper integer overflow checking.
5292 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5293 object is now static.
5295 * src/getargs.c (flags_argmatch): Return void, not int,
5296 to pacify ./configure --enable-gcc-warnings.
5298 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5299 since last_string is already defined to FLEX_PREFIX (last_string).
5301 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5303 Implement --warnings/-W.
5304 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5306 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5308 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5309 (warnings_args, warnings_types): New.
5310 (getargs, short_options, long_options): Accept -W/--warnings.
5311 Sort the options by alphabetical order, upper case letter right
5312 before its lower case.
5314 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5316 Change %merge result type clash warnings to errors. Discussed at
5317 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5318 * src/reader.c (record_merge_function_type): Use complain_at.
5319 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5320 declared later): Update test case results.
5322 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5324 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5325 to be in alphabetical order.
5326 (trace_args): Spelling fixes.
5328 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5330 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5331 so they don't collide with user-defined macros.
5332 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5333 this was never guaranteed, and now that we're using gnulib stdint,
5334 which defines int_fast16_t to long int, the problem is exposed.
5336 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
5338 * data/c.m4 (b4_basename): Simplify a bit, since we don't
5339 need the full POSIX semantics (and weren't implementing them
5342 Adjust to Autoconf 2.60 and today's gnulib.
5343 * bootstrap (gnulib_modules): Add stdint.
5344 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
5345 no longer copies it.
5346 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
5347 since stdint needs the former and wcwidth (which is now required
5348 by mbswidth) needs the latter.
5349 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
5350 work around a compatibility glitch between gettext 0.14.6 and
5352 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
5353 Do not check for uintptr_t, since new stdint module does the right
5355 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
5356 Add stdint.h, stdint_.h, wcwidth.h.
5357 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
5358 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
5359 stdint.m4, wchar_t.m4, wcwidth.m4.
5360 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
5361 usual order for ../lib/*.h files.
5362 (file_name_split): Use last_component, not base_name, to adjust
5364 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5365 for ../lib/*.h files.
5366 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5367 Define unconditionally, since we now assume the stdint module.
5368 * src/scan-skel.l: Include <dirname.h>.
5369 (BASE_QPUTS): Use last_component, not base_name.
5370 * src/system.h: Include <unlocked-io.h> in the usual order
5371 for ../lib/*.h files. Include <stdint.h> unconditionally,
5372 since we now use the stdint module.
5373 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5374 HAVE_UINTPTR_T, since we now use the stdint module.
5375 (base_name): Remove decl, since files now include <dirname.h>
5378 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5380 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5382 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5383 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5385 * tests/calc.at: Adjust.
5387 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5389 * data/c.m4 (b4_basename): New.
5390 (b4_syncline): Also output the location of its invocation (from
5392 (b4_user_action, b4_define_user_action, b4_user_actions)
5393 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5394 (b4_user_stype): New.
5395 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5397 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5399 In the grammar file, the first column is 1 not 0 on the first line as
5400 on every other line.
5401 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5402 * tests/input.at (Torturing the Scanner): Update output.
5404 * src/scan-gram.l (scanner_cursor): Declare it static.
5406 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5408 In warnings, say "previous declaration" rather than "first
5410 * src/symtab.c (redeclaration): Do that here.
5411 * src/reader.c (record_merge_function_type): In the case of a result
5412 type clash, report the previous declaration rather than the very first
5413 one in the grammar file.
5414 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5415 declared later): Add a third declaration to check this behavior.
5416 * tests/input.at (Incompatible Aliases): Update output.
5418 2006-06-27 Akim Demaille <akim@epita.fr>
5420 * doc/Doxyfile.in: New.
5421 * doc/Makefile.am: Use it.
5422 * src/lalr.h, src/symtab.h: Initial doxygenation.
5424 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5426 Don't miss %merge result type warnings just because the LHS types are
5427 declared after the %merge. This continues the effort of the previous
5429 * src/reader.c (get_merge_function): Don't set the merger type yet.
5430 (record_merge_function_type): New function for setting the merger type
5431 and checking for clashes.
5432 (grammar_current_rule_merge_set): Set the location of the %merge for
5434 (packgram): Invoke record_merge_function_type for each rule now that
5435 all symbol type declarations have been parsed.
5436 * src/reader.h (merger_list.type_declaration_location): New member
5437 storing the location of the first %merge from which the type for this
5438 merging function was derived.
5439 * src/symlist.h (symbol_list.merger_declaration_location): New member
5440 storing the location of a rule's %merge, if any.
5441 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5442 declared later): New test to catch the error fixed by the above patch.
5444 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5446 Get action warnings (grammar_rule_check) right even when symbol
5447 declarations appear after the rules. Discussed at
5448 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
5450 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
5451 Don't mistake the type of $$ in a midrule to be that of its parent
5453 * src/reader.c (grammar_current_rule_end): Don't invoke
5454 grammar_rule_check yet since not all symbol declarations may have been
5456 (grammar_midrule_action): Likewise.
5457 Don't record whether the midrule's $$ has been used yet since actions
5458 haven't been translated yet.
5459 Record the midrule's parent rule and its RHS index within the parent
5461 (grammar_current_rule_action_append): Don't translate the action yet
5462 since not all symbol declarations may have been parsed yet and, thus,
5463 warnings about types for $$, $n, @$, and @n can't be reported yet.
5464 (packgram): Translate the action and invoke grammar_rule_check now that
5465 all symbol declarations have been parsed.
5466 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5467 after parsing the entire grammar file, the symbol list here in the case
5468 of a midrule is actually the midrule's empty RHS, so reference its
5469 parent rule's RHS where necessary.
5470 On the other hand, now that you can already know it's a midrule, you
5471 aren't forced to think $$ has the same type as its parent rule's $$.
5472 (handle_action_at): In the case of a midrule, reference the parent rule
5474 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5476 (symbol_list_length): Now that this is invoked after all rules have
5477 been parsed, a NULL symbol (rather than a NULL symbol list node)
5478 terminates a rule. symbol_list_print already does this correctly.
5479 * src/symlist.h (symbol_list.midrule_parent_rule,
5480 symbol_list.midrule_parent_rhs_index): New members so that midrules can
5481 remember their relationships with their parents.
5482 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
5483 fixed by the above patch.
5484 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
5486 (Unused values): ... this old test case and...
5487 (Unused values before symbol declarations): ... this new test case.
5488 This one is the same as `Unused values' except that all symbol
5489 declarations appear after the rules in order to catch the rest of the
5490 errors fixed by the above patch.
5492 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5495 * src/reader.c (current_rule): Declare it static since it's no longer
5496 used outside this file.
5497 (grammar_current_rule_action_append): Remove redundant arguments from
5498 translate_rule_action invocation.
5499 * src/reader.h (current_rule): Remove this unused extern.
5500 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
5501 * src/scan-code.l (translate_rule_action): Likewise.
5503 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
5505 Clean up yesterday's patch.
5506 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
5508 * src/reader.c (grammar_current_rule_action_append): ... here for
5509 consistency with grammar_current_rule_symbol_append.
5510 * tests/regression.at (Braced code in declaration in rules section):
5511 Make yyerror and yylex static as usual.
5513 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
5515 Fix bug that mistakes braced code in a declaration in the rules section
5516 to be a rule action. Mentioned at
5517 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
5518 * src/scan-gram.l: Move midrule action detection from the start of the
5519 scanning of any braced code to...
5520 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
5521 action. For readability, use $2 and @2 rather than the equivalent
5523 * tests/regression.at (Braced code in declaration in rules section):
5524 New test to catch the error fixed by the above patch.
5526 Work on code readability some.
5527 * src/scan-code.l (current_rule): Get rid of this misleading and
5528 redundant declaration: it's actually extern'ed in reader.h.
5529 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
5530 translate_action): Add a rule argument and use it instead of the global
5532 (translate_rule_action): This already receives current_rule through an
5533 argument, so pass it on to translate_action instead of assigning
5534 current_rule to current_rule.
5535 (translate_symbol_action, translate_code): Pass rule = NULL to
5538 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
5540 Rename %before-definitions to %start-header and %after-definitions to
5541 %end-header. Don't use these declarations to separate pre-prologue
5542 blocks from post-prologue blocks. Add new order-independent
5543 declarations %before-header and %after-header as alternatives to the
5544 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
5545 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
5546 * NEWS (2.3+): Update for these changes.
5547 * data/glr.c (b4_before_definitions): Update to...
5548 (b4_start_header): ... this.
5549 (b4_after_definitions): Update to...
5550 (b4_end_header): ... this.
5551 * data/glr.cc: Likewise.
5552 * data/lalr1.cc: Likewise.
5553 * data/yacc.c: Likewise.
5554 * doc/bison.texinfo (The prologue): Update names, and replace remaining
5555 prologue blocks with %*-header declarations.
5556 (Calc++ Parser): Likewise.
5557 (Decl Summary): Update names.
5558 (Table of Symbols): Update description.
5559 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
5560 (PERCENT_END_HEADER): ... this.
5561 (PERCENT_BEFORE_DEFINITIONS): Update to...
5562 (PERCENT_START_HEADER): ... this.
5563 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5564 (declaration): Update token names and m4 macro names.
5565 When parsing %end-header and %start-header, invoke translate_code
5566 before muscle_code_grow, and no longer set global booleans to remember
5567 whether these declarations have been seen.
5568 Parse new %after-header and %before-header.
5569 * src/reader.c (before_definitions, after_definitions): Remove.
5570 (prologue_augment): Accept a new bool argument to specify whether to
5571 augment the pre-prologue or post-prologue.
5572 * src/reader.h (before_definitions, after_definitions): Remove these
5574 (prologue_augment): Add new bool argument.
5575 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
5576 (PERCENT_END_HEADER): ... this.
5577 (PERCENT_BEFORE_DEFINITIONS): Update to...
5578 (PERCENT_START_HEADER): ... this.
5579 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5580 * tests/actions.at (Printers and Destructors): Update names.
5582 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
5584 Add comparison operators for C++ location classes. Discussed at
5585 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
5586 * data/c++.m4 (b4_define_location_comparison): New boolean %define
5587 declaration indicating whether filename_type has an operator==. If
5588 filename_type is `std::string', it defaults to `1', `0' otherwise.
5589 * data/location.cc: Iff b4_define_location_comparison is `1', add
5590 operator== and operator!= for class position and for class location.
5593 * src/scan-action.l: Remove unused file.
5594 * src/symtab.c (symbol_printer_set): Use printer_location not
5595 destructor_location.
5596 * src/symtab.h (struct symbol): Replace incorrect source comment for
5598 * tests/input.at (Incompatible Aliases): Update output with correct
5601 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5603 Don't put the pre-prologue in the header file. For the yacc.c code
5604 file and the glr.c header and code files, move the pre-prologue before
5605 the token definitions. Add new %before-definitions and
5606 %after-definitions to declare code that will go in both the header file
5607 and code file. Discussed at
5608 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5609 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5611 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5612 * NEWS (2.3+): Describe these changes.
5613 * data/glr.c (b4_pre_prologue): Move from within to before...
5614 (b4_shared_declarations): ... this.
5615 Add new b4_before_definitions before b4_token_enums.
5616 Add new b4_after_definitions at the end.
5617 * data/glr.cc (b4_pre_prologue): Replace with...
5618 (b4_before_definitions): ... this in the header file.
5619 (b4_after_definitions): New near the end of the header file.
5620 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5621 code file right before including the header file.
5622 (b4_before_definitions): New in the previous position of
5623 b4_pre_prologue in the header file.
5624 (b4_after_definitions): New near the end of the header file.
5625 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5626 (b4_token_enums_defines): In the code file, move to right before
5627 YYSTYPE for consistency with the header file.
5628 (b4_before_definitions): New right before b4_token_enums_defines in
5629 both the header and code file.
5630 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5631 header and code file.
5632 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5633 of prologues for %union dependencies.
5634 (Decl Summary): In %defines description, mention the effect of
5635 %before-definitions and %after-definitions on the header file.
5636 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5637 than in the pre-prologue so that make check succeeds.
5638 (Table of Symbols): Add entries for %before-definitions and
5640 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5641 %before-definitions.
5642 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5643 (declaration): Parse those declarations and append to
5644 b4_before_definitions and b4_after_definitions, respectively.
5645 * src/reader.c (before_definitions, after_definitions): New bools to
5646 track whether those declarations have been seen.
5647 (prologue_augment): Add to the post-prologue if %union,
5648 %before-definitions, or %after-definitions has been seen.
5649 * src/reader.h (before_definitions, after_definitions): New extern's.
5650 * src/scan-gram.l: Scan the new declarations.
5651 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5652 prologue block in a %before-definitions or a %after-definitions based
5653 on whether the %union is declared.
5654 * tests/regression.at (Early token definitions with --yacc, Early token
5655 definitions without --yacc): Move tests for token definitions into the
5656 post-prologue since token names are no longer defined in the
5659 2006-06-20 Akim Demaille <akim@epita.fr>
5661 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5662 (symbol_get): Use it.
5663 * src/parse-gram.y: Use it.
5665 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5667 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5668 build succeeds when configured with --enable-gcc-warnings.
5670 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5672 * src/parse-gram.y (char_name): New function.
5673 (CHAR, STRING, string_content): For %printer, properly escape.
5674 (ID): Prefer fputs to fprintf.
5675 (id): Reindent to be consistent with other rules.
5676 Properly quote char.
5678 The Translation Project changed its way of publishing translations
5679 to maintainers. I haven't received any responses to my request
5680 for supporting the old way, or for documenting the new way. I
5681 have modified 'bootstrap' to use screen scraping
5682 (in this case, HTML scraping). This is unreliable and inelegant,
5683 but I don't see any better way. Yuck.
5684 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5685 (get_translations): New function, which uses HTML scraping to
5686 deduce locations of latest translations.
5687 Use this function to grab both bison and bison-runtime .po files.
5688 Don't bother priming the pump for the runtime-po domain any more,
5689 as it's now translated better than bison is.
5691 2006-06-19 Akim Demaille <akim@epita.fr>
5693 * src/scan-gram.l: No longer "parse" things after `%union' until
5694 `{'. Rather, return a single "%union" token.
5695 No longer make symbols: return strings, and leave the conversion
5696 to symbols to the parser.
5697 (SC_PRE_CODE, token_type): Remove.
5698 * src/parse-gram.y (%union): New field `character'.
5701 (ID, ID_COLON): Now that the scanner no longer makes them
5702 identifiers, adjust all uses to invoke symbol_get.
5703 (id_colon): New, wraps the conversion from string to symbol.
5704 (%union): Accept a possible union_name.
5705 (symbol): Now can be a char.
5706 * data/c.m4 (b4_union_name): Leave a default value.
5707 * data/glr.c, data/yacc.c: Use it.
5709 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5711 For associating token numbers with token names for "yacc.c", don't use
5712 #define statements unless `--yacc' is specified; always use enum
5713 yytokentype. Most important discussions start at:
5714 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5715 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5717 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5718 * NEWS (2.3+): Mention.
5719 * data/c.m4 (b4_yacc_if): New.
5720 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5722 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5723 on token name definitions.
5724 * src/getargs.c (usage): Capitalize `Yacc' in English.
5725 * src/output.c (prepare): Define b4_yacc_flag.
5726 * tests/regression.at (Early token definitions): Test that tokens names
5727 are defined before the pre-prologue not just before the post-prologue.
5728 Remove this test case and copy to...
5729 (Early token definitions with --yacc): ... this to test #define's.
5730 (Early token definitions without --yacc): ... and this to test enums.
5732 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5734 * NEWS: Reword the post-2.3 change to not be so optimistic about
5735 removing the old "look-ahead" spelling.
5736 Update previous look-ahead/lookahead change reports.
5737 * REFERENCES: look-ahead -> lookahead (since that's
5738 what he actually wrote).
5739 * doc/refcard.tex: look ahead -> lookahead,
5740 look-ahead -> lookahead
5742 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5744 For consistency, use `lookahead' instead of `look-ahead' or
5745 `look_ahead'. Discussed starting at
5746 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>

5819 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5821 * TODO: Add request from Nelson H. F. Beebe to be able to install
5822 Bison without installing the yacc script.
5824 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5826 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5827 and yytext if they're already #define'd.
5828 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5829 * src/scan-code-c.c: ... here.
5830 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
5833 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5835 Get Bison to build again when configured with --enable-gcc-warnings.
5836 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5838 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5839 loc argument as it shadows a global.
5840 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5843 * src/.cvsignore: Add scan-code.c.
5845 2006-06-07 Akim Demaille <akim@epita.fr>
5847 * src/scan-gram.l: Move the "add a trailing ; to actions" code
5849 * src/scan-code.l: here.
5850 * tests/input.at (Torturing the Scanner): Fix another location
5853 2006-06-07 Akim Demaille <akim@epita.fr>
5855 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
5857 2006-06-06 Akim Demaille <akim@epita.fr>
5859 Extract the parsing of user actions from the grammar scanner.
5860 As a consequence, the relation between the grammar scanner and
5861 parser is much simpler. We can also split "composite tokens" back
5863 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5864 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5866 * src/location.h, src/location.c (add_column_width)
5867 (location_compute): these.
5868 Fix the column count: the initial column is 0.
5869 (location_print): Be robust to ending column being 0.
5870 * src/location.h (boundary_set): New.
5871 * src/main.c: Adjust to scanner_free being renamed as
5873 * src/output.c: Include scan-code.h.
5874 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5876 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5877 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5878 which is now, again, a separate token.
5879 Adjust all dependencies.
5880 Whereever actions with $ and @ are used, use translate_code.
5881 (action): Remove this nonterminal which is now useless.
5882 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5883 (grammar_current_rule_action_append): Use translate_code.
5884 (packgram): Bound check ruleno, itemno, and rule_length.

5886 (last_string, last_braced_code_loc, max_left_semantic_context)
5887 (scanner_initialize, scanner_free, scanner_last_string_free)
5888 (gram_out, gram_lineno, YY_DECL_): Move to...
5889 * src/scan-gram.h: this new file.
5890 (YY_DECL): Rename as...
5892 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5893 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5894 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5895 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5896 Move these declarations, and...
5897 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5899 * src/flex-scanner.h: this new file.
5900 * src/scan-gram.l (rule_length, rule_length_overflow)
5901 (increment_rule_length): Remove.
5902 (last_braced_code_loc): Rename as...
5903 (gram_last_braced_code_loc): this.
5904 Adjust to the changes of the parser.
5905 Move all the handling of $ and @ into...
5906 * src/scan-code.l: here.
5907 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5908 (handle_action_dollar, handle_action_at): Move to...

5920 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5922 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5923 Use Akim's wording from
5924 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5926 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5928 Between Bison releases, manually append `+' to the previous Bison
5929 release number, and use that as a signal to automatically print the
5930 ChangeLog's CVS Id keyword from --version. Discussed starting at
5931 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5932 * ChangeLog: Add Id header.
5933 * configure.ac (AC_INIT): Append `+' to `2.3'.
5934 * src/.cvsignore: Add revision.c.
5935 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5936 (BUILT_SOURCES): Add revision.c.
5937 (revision.c): New target rule. This file defines a new global variable
5938 named revision. It initializes it with either the Id from ChangeLog
5939 or, if VERSION doesn't contain `+', with the empty string.
5940 * src/getargs.c (version): Print the value of revision.
5941 * src/revision.h: Extern revision.
5943 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5945 * NEWS: Version 2.3.
5946 * configure.ac (AC_INIT): Likewise.
5948 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5950 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5951 with no arguments, not as an object-like macro. This is for
5952 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5953 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5954 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5957 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5959 * src/getargs.c (usage): Back out yesterday's modification of the
5960 --help output so that we don't have to wait for translation before
5963 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5965 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5966 Problem reported by Akim Demaille.
5968 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5970 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5972 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5974 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5975 generated source code. Problem reported by Frans Englich in
5976 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5978 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5980 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5981 shell, not within 'make', so that 'make' by an ordinary builder
5982 (using GNU make) does not worry about configuring gzip. This also
5983 works around a bug reported independently by Keith Thompson and by
5984 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5985 stderr rather than stdout, messing up the build logs.
5987 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5989 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5990 to make sure that YYID will never be unused. This fixes a 'make
5991 maintainer-check' failure caused by the recent changes to the 'Trivial
5992 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5994 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5996 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5998 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5999 state before an empty RHS is always resolved here. Only the location
6000 of that state is guaranteed to be resolved, and that's enough. This
6001 fixes the remaining bug reported by Derek M. Jones in
6002 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6003 * tests/glr-regression.at (Uninitialized location when reporting
6004 ambiguity): Test the above case.
6005 Also, the embedded comments in this test case claim it checks the case
6006 of an empty RHS that has inherited the initial location. However, the
6007 corresponding LHS was already resolved, so yyresolveLocations didn't
6008 actually have reason to modify it. Fix this by forcing
6009 nondeterministic operation at the beginning of the parse.
6011 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6013 * data/c.m4 (b4_yy_symbol_print_generate):
6014 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6015 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6016 of the bugs reported today by Derek M Jones in
6017 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6018 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6019 defined to be a type name without parens or brackets.
6020 (Location Type): Similarly for YYLTYPE.
6021 * tests/regression.at (Trivial grammars): Put in a test for this
6022 bug that will be caught by 'make maintainer-check' (though not,
6023 alas, by 'make check' unless your compiler is picky).
6025 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6027 * NEWS: Version 2.2.
6028 * configure.ac (AC_INIT): Likewise.
6030 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
6032 * data/glr.c (yyreportTree): Make room in yystates for the state
6033 preceding the RHS. This fixes the segmentation fault reported by Derek
6035 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6036 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6037 to the user. Reported for yyreportTree by Derek M. Jones later in the
6039 * THANKS: Add Derek M. Jones.
6040 Update my email address.
6041 Fix typo in Steve Murphy's name.
6043 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6045 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6046 checking against YYLAST that caused the parser to miss a potential
6047 alternative in its diagnostic.
6048 Problem reported by Maria Jose Moron Fernandez in
6049 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6050 * data/lalr1.cc (yysyntax_error_): Likewise.
6051 * data/yacc.c (yysyntax_error): Likewise.
6052 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6053 tokens, in case we run into an older C compiler.
6054 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6055 Use them to check for the off-by-one error fixed above.
6057 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6058 YYSIZE_T, not size_t.
6059 * tests/regression.at (Trivial grammars): New test, to catch
6060 the error fixed by the above patch.
6062 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6064 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
6066 Reported by Steve Murphy.
6068 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6070 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
6071 * data/glr.cc: b4_location_flag is now b4_locations_flag.
6073 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6075 Implement --trace=m4.
6076 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6077 * src/output.c (output_skeleton): When set, pass -dV to m4.
6079 Factor the handling of flags in m4.
6080 * src/output.c (prepare): Rename the muscle names debug, defines,
6081 error_verbose to debug_flag, defines_flag, error_verbose_flag.
6082 * data/c.m4: Adjust.
6083 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
6084 Use b4_define_flag_if to define other b4_FLAG_if macros.
6085 (b4_location_if): As a consequence, rename as...
6086 (b4_locations_if): this, for consistency.
6087 Adjust all the skeletons.
6089 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6091 * etc/bench.pm: Shorten bench names.
6093 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6095 * src/output.h, src/output.c (error_verbose): Move to...
6096 * src/getargs.h, src/getargs.c: here.
6098 Adjust dependencies.
6100 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6102 * data/c.m4 (b4_copyright): Put the special exception for Bison
6103 skeletons here, so we don't have to put it in each skeleton. All
6104 uses changed. Suggested by Akim Demaille. Also, wrap the
6105 copyright notice, in case it is longer than 80 columns. Replace
6106 comma by newline after title.
6108 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6110 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
6111 incompatibility, not a bug. Mention that it wasn't fixed as of
6114 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6116 * examples/extexi: Enforce the precedence of concatenation over
6118 Reported by Tommy Nordgren.
6120 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6122 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
6123 with the member "token".
6124 Reported by Martin Nylin.
6126 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
6128 * data/glr.c: Switch to Bison 2.2 special-exception language in
6129 the copyright notice. Use more-regular format for titles and
6131 * data/glr.cc: Likewise.
6132 * data/location.cc: Likewise.
6133 * data/yacc.cc: Likewise.
6134 * doc/bison.texinfo (Conditions): Document this.
6135 * NEWS: likewise. Upgrade version to 2.2.
6137 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
6139 * data/glr.cc: Remove dead code.
6141 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6143 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
6144 that variable and the line breaks the bootstrap. Problem reported
6145 by Juan M. Guerrero.
6147 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
6149 * doc/bison.texinfo (Multiple start-symbols): New.
6151 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
6153 * etc/README, etc/bench.pl: New.
6155 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
6157 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
6159 Reported by Mickael Labau.
6160 * tests/input.at (Torturing the Scanner): Test it.
6162 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
6164 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
6165 Problem reported by Bob Rossi.
6167 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
6169 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
6170 and didn't really work.
6171 For the index, use @ifnotinfo, not @iftex.
6172 Minor cleanups of spacing and terminology.
6174 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6176 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
6177 of AT_NAME_PREFIX when %name-prefix is not used.
6179 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6181 Apply --prefix to C++ skeletons too: they change the namespace.
6182 The test suite already exercize these cases.
6183 * data/c++.m4 (b4_namespace): New.
6184 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
6185 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
6186 * data/yacc.c, data/glr.c: Remove a useless `[]'.
6187 * doc/bison.texinfo: Document it.
6188 (Option Cross Key): Use @multitable in all formats. It looks
6189 nicer, even in TeX outputs.
6190 (Rules): Use the same code whatever the output type is.
6191 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
6192 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
6193 * tests/calc.at: Use it, instead of hard coding `yy'.
6195 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
6197 * TODO: Remove dead items.
6199 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
6201 * doc/FAQ: Remove, merged into...
6202 * doc/bison.texinfo (FAQ): this.
6203 * doc/Makefile.am (EXTRA_DIST): Adjust.
6205 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
6207 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
6209 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
6210 * doc/bison.texinfo (Calc++ Scanner): Use it.
6212 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
6214 Fix two nits reported by twlevo, plus one more that I discovered.
6216 * src/assoc.h (assoc_to_string): Give a name to the arg, as
6217 this is the usual Bison style.
6218 * src/location.h (location_print): Likewise.
6220 * src/reader.h (token_name): Likewise.
6222 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
6224 Fix some nits reported by twlevo.
6225 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6226 and "POSIX". Use more-modern syntax for URLs. Mention C++
6227 and ask for Java. Don't hardwire OS version numbers. Add
6229 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
6230 * src/conflicts.c (solved_conflicts_obstack): Now static.
6232 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
6234 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
6235 page. Say "you can use it" not "you may use it" as on the web page;
6236 we're describing capabilities not granting permission.
6238 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
6240 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6241 shadowing warnings. Use usual patter for iterating through RHS.
6242 * tests/glr-regression.at
6243 (Uninitialized location when reporting ambiguity):
6244 Modify yylex so that it uses its argument, rather than trying
6245 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6246 const char -> char const.
6248 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6249 Don't use tabs inside commands; it messes up 'ps'.
6250 Problem reported by twlevo.
6252 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
6254 * tests/glr-regression.at (Uninitialized location when reporting
6255 ambiguity): New test case.
6256 * data/glr.c (yyresolveLocations): New function, which uses
6258 (yyresolveValue): Invoke yyresolveLocations before reporting an
6260 * doc/bison.texinfo (Default Action for Locations): Note
6261 YYLLOC_DEFAULT's usage for ambiguity locations.
6262 (GLR Semantic Actions): Cross-reference those notes.
6264 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6266 * tests/glr-regression.at (Leaked semantic values when reporting
6267 ambiguity): Remove unnecessary union and type declarations.
6268 (Leaked lookahead after nondeterministic parse syntax error): New test
6270 * data/glr.c (yyparse): Check for zero stacks remaining before
6271 attempting to shift the lookahead so that you don't lose it.
6273 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6275 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6276 * tests/glr-regression.at (Leaked semantic values when reporting
6277 ambiguity): New test case.
6278 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6279 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6280 now unnecessary yystackp parameter.
6281 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6282 destructors can be called.
6284 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6285 in existing testcases.
6287 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6289 Don't leak semantic values for parent RHS when a user action cuts the
6290 parser, and clean up related code a bit.
6291 * tests/glr-regression.at (Leaked merged semantic value if user action
6292 cuts parse): Rename to...
6293 (Leaked semantic values if user action cuts parse): ... this. Add check
6294 for leaked parent RHS values.
6295 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6296 between an unresolved state (non-empty chain of semantic options) and
6297 an incomplete one (signaled by an empty chain).
6298 (yyresolveStates): Document the interface. Move all manipulation of a
6299 successfully or unsuccessfully resolved yyGLRState to...
6300 (yyresolveValue): ... here so that yyresolveValue always leaves a
6301 yyGLRState with consistent data and thus is easier to understand.
6302 Remove the yyvalp and yylocp parameters since they are always just
6303 taken from the yys parameter. When reporting a discarded merged value
6304 in debugging output, note that it is incompletely merged. Document the
6306 (yyresolveAction): If resolving any of the RHS states fails, destroy
6307 them all rather than leaking them. Thus, as long as user actions are
6308 written to clean up the RHS correctly, yyresolveAction always cleans up
6309 the RHS of a semantic option. Document the interface.
6311 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
6313 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
6314 led to a segmentation fault in GNU Pascal. Problem reported
6317 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
6319 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
6320 mid-rule action inside a nonterminal symbol in order to declare a
6321 destructor for its semantic value.
6323 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
6325 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
6326 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
6327 __cplusplus && ! defined _STDLIB_H && !
6328 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
6329 defined free))]: Include <stdlib.h> rather than rolling our own
6330 declarations of malloc and free, to avoid problems with
6331 incompatible declarations (using 'throw') C++'s stdlib.h. This
6332 should fix Debian bug 340012
6333 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
6334 reported by Guillaume Melquiond.
6336 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
6338 * NEWS: Clarify symbols versus types in unused-value warnings.
6340 * configure.ac (AC_INIT): Bump version number.
6342 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
6344 * NEWS: Version 2.1a.
6345 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
6346 since C99 requires this.
6348 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
6350 * m4/c-working.m4: New file.
6351 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
6353 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
6355 * Makefile.maint: Merge from coreutils.
6357 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
6359 More portability fixes for problems summarized by Nelson H. F. Beebe.
6361 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
6362 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
6363 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
6364 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
6365 messes up because C++ code is compiled in 32-bit mode but linked
6368 2006-02-08 Paul Eggert <eggert@cs.ucla.edu>
6370 More portability fixes for problems summarized by Nelson H. F. Beebe.
6372 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
6373 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
6375 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6376 nodist_PROGRAMS, since we don't need to actually compile the
6377 example if we're just doing a plain 'make'. This avoids bothering
6378 the installer unnecessarily about problems due to weird C++
6381 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
6383 More portability fixes for problems summarized by Nelson H. F. Beebe.
6385 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
6386 than #include "...", and compile with -I'.'. The old method was
6387 not portable, according to Posix and the C standard, and it does
6388 not work with Sun C 5.7, where previous #line directives affect
6389 the working directory used in later #include "..." directives.
6391 2006-02-06 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6393 Various DJGGP specific issues in /djgpp
6395 2006-02-02 Paul Eggert <eggert@cs.ucla.edu>
6397 More portability fixes for problems summarized by Nelson H. F. Beebe.
6399 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
6400 '#include <map>' works and that you can apply ++ to iterators.
6402 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
6404 Work around portability problems summarized by Nelson H. F. Beebe in
6405 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
6407 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
6408 that '#include <string>' works.
6410 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
6411 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
6412 "warning: sorry: semantics of inline function static data `const
6413 unsigned char translate_table[262]' are wrong (you'll wind up with
6416 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
6417 or, xor to not_, and_, or_, and xor_, respectively. This works
6418 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
6419 random system header somewhere that includes the equivalent of
6422 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
6423 -E" works; it apparently doesn't work with PathScale EKO Compiler
6426 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
6428 During deterministic GLR operation, user actions should be able to
6429 influence the parse by changing yychar. To make this easier to fix and
6430 to make glr.c easier to evolve in general, don't maintain yytoken in
6431 parallel with yychar; just compute yytoken when needed.
6432 * tests/glr-regression.at (Incorrect lookahead during deterministic
6433 GLR): Check that setting yychar in a user action has the intended
6435 * data/glr.c (yyGLRStack): Remove yytokenp member.
6436 (yyclearin): Don't set *yytokenp.
6437 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
6438 yychar rather than *yytokenp to determine the current lookahead.
6439 Compute yytoken locally when needed.
6440 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
6443 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
6444 after `--report' documentation.
6446 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
6448 * src/parse-gram.y (grammar_declaration): Location of printer
6449 symbol is @1, not list->location. Bug reported by twlevo.
6450 * tests/input.at (Incompatible Aliases): Adjust to above change.
6452 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
6454 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
6455 all the test at once. This makes the output easier to read in the
6458 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6459 got from <http://bro-ids.org/download.html>. The bug is that
6460 when two actions appeared in succession, the second one was
6461 scanned before the first one was added to the grammar rule
6462 as a midrule action. Bison then output the incorrect warning
6463 "parse.y:905.17-906.36: warning: unused value: $3".
6464 * src/parse-gram.y (BRACED_CODE, action): These are no longer
6465 associated with a value.
6466 (rhs): Don't invoke grammar_current_rule_action_append.
6467 (action): Invoke it here instead.
6468 * src/reader.c (grammar_midrule_action): Now extern.
6469 (grammar_current_rule_action_append): Don't invoke
6470 grammar_midrule_action; that is now the scanner's job.
6471 * src/reader.h (last_string, last_braced_code_loc):
6472 (grammar_midrule_action): New decls.
6473 * src/scan-gram.l (last_string): Now extern, sigh.
6474 (last_braced_code_loc): New extern variable.
6475 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
6476 rule already has an action.
6477 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
6478 * tests/input.at (AT_CHECK_UNUSED_VALUES):
6479 Add some tests to check that the above changes fixed the bug.
6481 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
6483 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
6484 All used changed. Check whether the symbol has a destructor,
6485 not whether it is typed.
6486 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
6487 that the values are still reported as unused. All line numbers
6490 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
6492 Work around a bug in bro 0.8, which underparenthesizes its
6493 definition of YYLLOC_DEFAULT.
6494 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
6496 * data/lalr1.cc: Likewise.
6497 * data/yacc.cc: Likewise.
6499 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
6501 Work around a bug in Pike 7.0, and give the Pike folks a
6502 better way to override the usual int widths.
6503 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
6504 user can override the types.

6725 in the yychar entry.
6726 In the yychar entry, remove mention of the local yychar case (pure
6727 parser) since this is irrelevant information when writing semantic
6728 actions and since it's already discussed in `Table of Symbols' where
6729 yychar is otherwise described as an external variable.
6730 In the yychar entry, don't call it the `current' look-ahead since it
6731 isn't when semantic actions are deferred.
6732 In the yychar and yyclearin entries, add note about deferred semantic
6734 Add yylloc and yylval entries discussing look-ahead usage.
6735 (Look-Ahead Tokens): When discussing yychar, don't call it the

6758 members to store the current lookahead to be used by the deferred
6760 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6761 from which the RHS is taken. Set the lookahead members of the new
6762 yySemanticOption according to the lookahead status for stack yyk.

6764 yyaddDeferredAction.
6765 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

6790 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6792 * data/glr.c (yyresolveValue): When merging semantic options, if at
6793 least one user action succeeds but a later one cuts the parse, then
6794 destroy the semantic value before returning rather than leaking it.
6795 (yyresolveStates): If a user action cuts the parse and thus
6796 yyresolveValue fails, ignore the (unset) semantic value rather than
6797 corrupting the yyGLRState, and empty the semantic options list since
6798 the user actions should have called all necessary destructors.
6799 Simplify code with YYCHK.
6800 * tests/glr-regression.at (Corrupted semantic options if user action
6801 cuts parse): New test case.
6802 (Undesirable destructors if user action cuts parse): New test case.

7100 sed out the final state number.
7102 Work around portability problem on Solaris 10: flex-generated
7103 files include <stdio.h> before <config.h>, which messes up
7104 because the latter defines __EXTENSIONS__. Address the problem
7105 by creating two new little files that include <config.h> first,
7106 then include the flex-generated files. Rewrite everyone else

7156 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
7158 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

7184 it's no longer just a file.
7185 * data/glr.c: Grant a special exception for C GLR parsers, that
7186 reads like the already-existing exception for C LALR(1) parsers.

7445 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7447 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
7449 Undo the parts of the unlocked-I/O change that substituted
7450 putc or puts for printf. This might hurt performance a bit,
7451 but some people prefer the printf style.
7452 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
7453 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

7474 unused-variable warnings.
7476 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

7480 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
7482 Use unlocked I/O for a minor performance improvement on hosts like
7483 GNU/Linux and Solaris that support unlocked I/O. The basic idea
7484 is to use the gnlib unlocked-io module, and to prefer putc and
7485 puts to printf when either will work (since the latter doesn't
7486 come in an unlocked flavor).
7487 * bootstrap (gnulib_modules): Add unlocked-io.

7506 * src/system.h: Include unlocked-io.h rather than stdio.h.
7508 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

7554 to allow support for non-posix systems. This is a no-op function
7557 * lib/subpipe.h: New function end_of_output_subpipe() added
7558 to allow support for non-posix systems. This is a no-op function
7561 * src/output.c (output_skeleton): Use end_of_output_subpipe() to

7601 (parser::semantic_value): Now a full definition instead of an
7602 indirection to YYSTYPE.

7646 local variables whose names begin with 'yy'.
7647 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7648 Trivial changes from Joel E. Denny.
7650 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7652 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7653 don't use alloca any more.
7655 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7656 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7657 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

7668 This works a bit better with glibc, if user code has already included
7670 * doc/bison.texinfo (Bison Parser): Document that users can't
7671 arbitrarily use malloc and free for other purposes. Document

7687 (yysyntax_error): New function.
7688 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7689 multiple syntax errors are reported, and alloca is being used.
7690 Instead, reallocate buffers twice as big each time, so that
7691 we waste at most half the allocated memory. Start with a small
7692 (128-byte) buffer that will suffice in most cases anyway.
7693 Use yysyntax_error to do most of the work.
7695 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7696 yynerrs is the number of errors reported, not the number of

7705 2005-09-19 Akim Demaille <akim@epita.fr>
7707 Remove the traits, failed experiment.
7708 It never proved useful, and anyway because of the current
7709 definition, it was not possible to have several specialization of
7710 this traits, making it useless.
7711 * data/lalr1.cc (yy:traits): Remove.
7712 Inline its definitions in the parser class.
7714 2005-09-19 Akim Demaille <akim@epita.fr>

7737 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7738 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7739 is not defined. This is an awful hack, but it's enough for now.
7740 All callers changed.
7741 * tests/glr-regression-at (make_value): Args are const pointers now,
7742 to avoid GCC warning.
7743 (Duplicated user destructor for lookahead): New test. Currently
7744 skipped. It fails on my host but I'm not sure it'll always fail.
7746 2005-09-16 Akim Demaille <akim@epita.fr>
7748 * src/symtab.h (struct symbol): Declare the printer and destructor
7749 as const, to avoid accidental calls to free.

7764 2005-09-16 Akim Demaille <akim@epita.fr>
7766 * data/lalr1.cc (yylex_): Remove, inline its code.
7767 (yyreport_syntax_error_): Remove, replaced by...
7768 (yysyntax_error_): this which returns a string and leaves to the
7769 caller the call to the users' error function.
7770 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7771 Move from members of the parser object...
7772 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

7796 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
7797 do anything if $@ exists. This reverts part of the 2005-07-07
7800 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7802 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7803 contains obsolete information and isn't worth distributing as a
7804 separate file anyway.
7805 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7806 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

7813 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
7814 Suggested by twlevo@xs4all.nl.
7816 * data/glr.c (YYCHK1): Do not assume YYE is in range.

7818 Problem reported by twlevo@xs4all.nl.
7820 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7821 standards. Use "file name" or "file" or "name", depending on
7823 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7824 not to hack/foo.tab.c.
7825 (Calc++ Top Level): 2nd arg of main is not const.
7826 * data/glr.c: b4_filename -> b4_file_name.

7921 * configure.ac (AC_INIT): Bump to 2.0c.
7923 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
7925 * NEWS: Version 2.0b.
7927 * Makefile.am (SUBDIRS): Put examples before tests, so that
7928 "make check" doesn't finish with "All 1 tests passed".
7930 * tests/regression.at (Token definitions): Don't rely on
7931 AT_PARSER_CHECK for data that contains backslashes. It currently
7932 uses 'echo', and 'echo' isn't portable if its argument contains
7933 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7934 that the byte '\0xff' is not printable in the C locale; it is,
7935 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7936 not printable, so use '\0x81' to test.
7938 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7939 version of GCC, since the macro is used with non-GCC compilers.
7941 Fix core dump reported by Pablo De Napoli in
7942 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7943 * tests/regression.at (Invalid inputs with {}): New test.
7944 * src/parse-gram.y (token_name): Translate type before using
7947 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7948 the user's name space. All uses changed to __attribute__
7950 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7951 Add __attribute__ ((__noreturn__)).
7953 * etc/clcommit: Remove. We weren't using it, and it failed
7954 "make maintainer-distcheck".
7955 * Makefile.maint: Merge from coreutils.
7956 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7957 (syntax-check-rules): Change list of rules as described below.
7958 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

7968 Use grep -n, to make it easier to find violations.
7969 Use CVS_LIST and CVS_LIST_EXCEPT.
7970 (header_regexp, h_re): Remove.
7972 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
7973 (my-distcheck): Use more-modern GCC flags.
7974 (signatures, %.asc): Remove.
7975 (rel-files, announcement): Remove signatures.
7976 Restore old updating code, even though we don't use it, so
7977 that we're the same as coreutils.
7978 (alpha, beta, major): Depend on news-date-check.
7979 Make the upload commands.
7981 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
7982 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
7983 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
7984 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

7988 * tests/sets.at: Likewise.
7990 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7991 we comment out the Autoconf version number.
7992 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7993 it's error-prone and "make maintainer-distcheck" rejects it.
7995 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7996 Indent calls to "error" to pacify "make maintainer-distcheck",
7997 when the calls are not intended to be translated.
7998 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
8000 * src/Makefile.am (DEFS): Use +=, to pacify
8001 "make maintainer-distcheck".
8002 (bison_SOURCES): Add scan-skel.h.
8003 (sc_tight_scope): New rule, from coreutils.
8005 * src/files.c (src_extension, header_extension):
8006 Now static, not extern.
8007 * src/getargs.c (short_options): Likewise.
8008 * src/muscle_tab.c (muscle_table): Likewise.
8009 * src/parse-gram.y (current_class, current_type, current_prec):
8011 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8012 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8013 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8014 void, to avoid warning when NLS is disabled.
8015 * src/output.c: Include scan-skel.h.
8016 (scan_skel): Remove decl, since scan-skel.h does this.
8018 Indent calls to "error" to pacify "make maintainer-distcheck".
8019 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8020 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8021 "make maintainer-distcheck".
8022 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8023 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8024 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8025 (skel_lex_destroy, scan_skel): Move these decls to...
8026 * src/scan-skel.h: New file.
8027 * src/uniqstr.c (uniqstr_assert):
8028 Indent calls to "error" to pacify "make maintainer-distcheck".
8030 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8033 * tests/torture.at: Revamp to avoid misuse of atoi that
8034 "make maintainer-distcheck" complained about.
8036 * examples/extexi (message): Don't print a message more than once,
8037 and omit line-number decoration that makes Emacs compile think
8038 that informative messages are worth worrying about.
8040 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8042 * configure.ac: Update version number.
8044 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8046 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8047 autogenerated by the maintainer.
8048 * examples/calc++/.cvsignore: Add *.yy.
8050 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8051 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8052 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8054 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8056 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8057 from maintainer-distcheck about casting the argument of 'free'.
8059 * NEWS: Mention recent yytname changes.
8060 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8062 * bootstrap: For translations that have not yet been upgraded to
8063 the new runtime-po domain, prime the pump by extracting the
8064 relevant strings from the obsolete translations. This code can be
8065 removed once the bison-runtime domain has been translated by each
8068 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8069 now that token names are already quoted.
8071 Fix problem reported by Anthony Heading.
8072 * data/glr.c (YYTOKEN_TABLE): New macro.
8073 (yytname): Define if YYTOKEN_TABLE.
8074 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8075 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8076 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8077 * src/output.c (prepare_symbols): Output token_table_flag.
8079 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8081 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
8082 again if the first call fails.
8084 * data/glr.c (yytnamerr): New function.
8085 (yyreportSyntaxError): Use it to dequote most string literals.
8086 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8087 with other skeletons. All uses changed.
8088 (yytnameerr_): New function.
8089 (yyreport_syntax_error): Use it to dequote most string literals.
8090 * data/yacc.c (yytnamerr): New function.
8091 (yyerrlab): Use it to decode most string literals.
8092 * doc/bison.texinfo (Decl Summary, Calling Convention):
8093 Clarify quoting convention of yytname.
8094 * src/output.c (prepare_symbols): Quote all names. This undoes
8095 the 2005-04-17 change, which is now accomplished (mostly) via
8096 changes in the parsers as described above.
8097 * tests/regression.at (Token definitions, Web2c Actions):
8098 Undo most 2005-04-17 change here, too.
8100 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8102 Fix more problems reported by twlevo@xs4all.nl.
8103 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8104 remove trailing spaces. This loses the exit status of ./types,
8105 and isn't needed since ./types shouldn't be emitting trailing
8107 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8108 as the stack isn't valid in that case.
8110 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8111 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8112 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8113 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8115 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8116 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
8117 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
8120 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8121 overly-picky compilers that reject 'char *foo = "bar";'.
8123 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8124 to FILE * parameter, not to stderr. This fixes a typo introduced
8125 in the 2005-07-12 change.
8127 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8128 warnings from GCC 4.
8130 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
8131 (yyglrShiftDefer, yysplitStack):
8132 Remove unused parameters b4_pure_formals. All uses changed.
8133 (yyglrShift): Remove unused parameters b4_user_formals.
8135 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
8137 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
8139 Destructor cleanups and regularization among the three skeletons.
8140 * NEWS: Document the behavior changes.
8141 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8142 stack before failing, as the cleanup code will do it for us now.
8143 * data/lalr1.cc (yyerrlab): Likewise.
8144 * data/glr.c (yyparse): Pop everything off the stack before
8145 freeing it, so that destructors get called properly.
8146 * data/lalr1.cc (yyreturn): Likewise.
8147 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8148 This is more consistent.
8149 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8150 why destructors might be called. 1.875 -> 2.1.
8151 (Destructor Decl, Decl Summary, Table of Symbols):
8152 Some English-language cleanups for %destructor.
8153 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8154 Add output line for destructor of start symbol.
8155 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
8156 because of that same extra output line.
8158 * NEWS: Document minor wording changes in diagnostics of
8159 Bison-generated parsers.
8160 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
8161 Remove unused formals. All uses changed.
8162 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8163 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8164 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8165 Rename yyoverflowab to yyexhaustedlab.
8166 When memory exhaustion occurs during syntax-error reporting,
8167 report it separately rather than in a single diagnostic; this
8169 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8170 (Memory Exhausted): Renamed from Parser Stack Overflow.
8171 Revamp wording slightly to prefer "memory exhaustion".
8172 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
8174 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
8176 Add i18n support to the GLR skeleton. Partially fix the C++
8177 skeleton; a C++ expert needs to finish this. Remove debugging
8178 msgids; there's little point to having them translated, since they
8179 can be understood only by someone who can read the
8180 (English-language) source code.
8182 Generate runtime-po/bison-runtime.pot automatically, so that we
8183 don't have to worry about garbage getting in that file. We'll
8184 make sure after the next official release that old msgids don't
8186 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8188 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8190 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8191 Fix typos in explanations of the runtime file.
8192 * bootstrap: Change gettext keyword from YYI18N to YY_.
8193 Use standard Makefile.in.in in runtime-po, since we'll arrange
8194 for backward-compatible bison-runtime.po files in a different way.
8195 * data/glr.c (YY_): New macro, from yacc.c.
8196 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8197 Translate messages intended for users.
8198 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8199 the wording in the other skeletons. We don't know that the memory
8201 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8202 Use same method that yacc.c uses.
8203 Don't translate debugging messages.
8204 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8205 it doesn't work (yet), and requires C++ expertise to fix.
8206 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8207 Move defn to a more logical place, to be consistent with other
8209 Don't translate debugging messages.
8210 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8211 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8212 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8213 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8215 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8216 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8218 * tests/glr-regression.at (Badly Collapsed GLR States):
8220 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8221 yylex should return 0 at EOF rather than aborting.
8223 Improve tests for stack overflow in GLR parser.
8224 Problem reported by twlevo@xs4all.nl.
8225 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8227 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8228 can handle the problem.
8229 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8230 (yyparse): New local variable yyresult to record the result.
8231 Use result of setjmp to set it, rather than storing itinto
8233 (yyDone): Remove label.
8234 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8235 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8236 if YYABORT is used).
8237 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8238 yyparse status; put status > 1 into diagnostic.
8239 Check that status==2 works.
8240 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8241 Use exit status 3 for failure to open (which shouldn't happen).
8243 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8245 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8246 1 on syntax error; just let yyparse do its thing.
8247 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8248 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8249 (Exploding the Stack Size with Alloca):
8250 (Exploding the Stack Size with Malloc):
8251 Expect exit status 2, not 1, since the parser is supposed to blow
8252 its stack. Problem reported by twlevo@xs4all.nl.
8254 * data/glr.c (yyparse): Don't assume that the initial calls
8255 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8256 Print a stack-overflow message and fail instead.
8257 Initialize the line-number information before creating the stack,
8258 so that the stack-overflow message can report line zero safely.
8260 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8262 Fix problems reported by twlevo@xs4all.nl.
8263 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8264 (yyuserMerge): Provide a default case if b4_mergers is empty.
8265 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8266 * tests/glr-regression.at
8267 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8268 Add casts to pacify C++ compilers.
8269 * tests/glr-regression.at (Improper merging of GLR delayed action
8270 sets): Declare yylex before using it.
8271 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8272 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8273 test for valgrind; valgrind is independent of g++.
8274 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8275 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8276 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8277 Use a destructor, so that we can expand the stack. Change
8278 YYSTYPE to char * so that we can free it. Cast result of malloc.
8280 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8282 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8283 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8285 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8287 * PACKAGING: New file, suggested by Bruno Haible and taken from
8288 similar wording in gettext's PACKAGING file.
8289 * NEWS: Mention PACKAGING.
8290 * Makefile.am (EXTRA_DIST): Add PACKAGING.

8294 * NEWS: Document recent i18n improvements.
8295 * bootstrap: Get runtime translations into runtime-po.
8296 Create runtime-po files automatically, if possible.
8297 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8298 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8299 does not infringe on the user's name space.
8300 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8301 * doc/bison.texinfo (Internationalization): Revamp the English
8302 and Texinfo syntax a bit, to try to make it clearer.
8303 (Bison Options, Option Cross Key): Mention --print-localedir.
8304 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8305 YYENABLE_NLS. Quote a bit more.
8306 * runtime-po/.cvsignore: New file.

8308 * runtime-po/Rules-quot: Remove; now created by bootstrap.

8315 * runtime-po/Makevars: Likewise.
8316 * runtime-po/LINGUAS: Likewise.
8317 * runtime-po/de.po: Likewise; we will rely on the translation project
8318 to maintain this, so "bootstrap" should get it.
8319 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8321 * src/main.c (main): Bind the bison-runtime domain, too.
8323 2005-07-12 Bruno Haible <bruno@clisp.org>
8325 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8326 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8327 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8328 * runtime-po: New directory.
8329 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8330 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8331 * runtime-po/Rules-quot: New file, copied from po/.
8332 * runtime-po/quot.sed: Likewise.
8333 * runtime-po/boldquot.sed: Likewise.

8343 * m4/bison.m4: New file.
8344 * Makefile.am (SUBDIRS): Add runtime-po.
8345 (aclocaldir, aclocal_DATA): New variables.
8346 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
8348 * src/getargs.c (usage): Document --print-localedir option.
8349 (PRINT_LOCALEDIR_OPTION): New enum item.
8350 (long_options): Add --print-localedir option.
8351 (getargs): Handle --print-localedir option.
8352 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
8353 (Internationalization): New section.
8355 2005-07-12 Akim Demaille <akim@epita.fr>
8357 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
8358 for consistency with the rest of the code.
8359 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
8362 2005-07-12 Akim Demaille <akim@epita.fr>
8364 * src/parse-gram.y: Use %printer instead of YYPRINT.
8366 2005-07-12 Akim Demaille <akim@epita.fr>
8368 * src/symtab.h, src/symtab.c (symbol_print): New.
8369 * src/symlist.h, src/symlist.c (symbol_list_print): New.
8370 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
8372 2005-07-12 Akim Demaille <akim@epita.fr>
8374 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8375 b4_at_dollar and b4_dollar_dollar.
8377 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8379 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8380 and Pennello's paper.
8382 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8384 * data/yacc.c (yyparse): Undo previous patch. Instead,
8385 set yylsp[0] and yyvsp[0] only if the initial action
8386 sets yylloc and yylval, respectively.
8388 * data/yacc.c (yyparse): In the initial action, set
8389 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8390 This avoids the use of undefined variables if the initial
8391 action does not set yylloc and/or yylval.
8393 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8395 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8396 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8397 Remove from CVS. These files are automatically generated.
8398 * examples/extexi: Clarify that this file is now part of Bison,
8399 not GNU M4, and that it works with any POSIX-compatible Awk.
8400 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8401 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8402 so that we also get calc++-parser.yy. Geneate it.
8403 Use $(AWK), not gawk, since any conforming Awk will do.
8404 Put comment before action, since older 'make' can't handle comment
8406 $(BUILT_SOURCES): List all built sources, not just some of them.
8407 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8408 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8409 $($(calc_sources_generated)): Remove unnecessary test for existence
8410 of target. (This had a shell syntax error anyway; a stray "x".)
8411 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8413 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8415 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8416 implied by the other modules.
8418 2005-07-06 Akim Demaille <akim@epita.fr>
8420 Bind examples/calc++ to the package.
8421 * examples/calc++/Makefile: Remove, replaced by...
8422 * examples/calc++/Makefile.am: ... this new file.
8423 * examples/calc++/test: Remove input.
8424 * examples/calc++/compile: Remove.
8425 * examples/Makefile.am: New.
8426 * configure.ac, Makefile.am: Adjust.
8427 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
8429 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
8431 * data/glr.c (yyFail): Drastically simplify; since the format argument
8432 never had any % directives, we can simply pass it to yyerror.
8433 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
8434 be modified later, as that is the usual style in glr.c.
8435 Problems reported by Paul Hilfinger.
8437 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
8438 and size overflow errors.
8439 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
8440 in case the user prolog sets feature-test macros like _GNU_SOURCE.
8441 (YYSIZEMAX): New macro.
8442 (yystpcpy): New function, taken from yacc.c.
8443 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8444 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8445 so that we don't have to maintain their signatures.
8446 (yyFail): Check for buffer overflow, by using vsnprintf rather
8447 than vsprintf. Allocate a bigger buffer if possible.
8448 Report an error if buffer allocation fails.
8449 (yyStackOverflow): New function.
8450 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8451 the initialization was successful. It might fail if storage was
8453 (yyexpandGLRStack): Add more checks for storage allocation failure.
8454 Use yyStackOverflow to report failures.
8455 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8456 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8457 Don't assume stack number fits in int.
8458 (yysplitStack): Check for storage allocation failure.
8459 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8460 can print diagnostics on storage allocation failure. All callers
8462 (yyresolveValue): Use yybool for boolean.
8463 (yyreportSyntaxError): Check for size-calculation overflow.
8464 This code is taken from yacc.c.
8465 (yyparse): Check for storage allocation errors when allocating
8468 2005-07-05 Akim Demaille <akim@epita.fr>
8470 Extract calc++ from the documentation.
8471 * doc/bison.texinfo (Calc++): Add the extraction marks.
8472 * examples/extexi: New, from the aborted GNU Programming 2E.
8473 Separate the different paragraph of a file with empty lines.
8474 * examples/Makefile: Use it to extract the whole calc++ example.
8476 2005-06-24 Akim Demaille <akim@epita.fr>
8478 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
8481 2005-06-22 Akim Demaille <akim@epita.fr>
8483 * doc/bison.texinfo (C++ Language Interface): First stab.
8484 (C++ Parsers): Remove.
8486 2005-06-22 Akim Demaille <akim@epita.fr>
8488 * data/lalr1.cc (yylex_): Honor %lex-param.
8490 2005-06-22 Akim Demaille <akim@epita.fr>
8492 Start a set of simple examples.
8493 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
8494 * examples/calc++/calc++-driver.hh,
8495 * examples/calc++/calc++-parser.yy,
8496 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
8497 * examples/calc++/compile, examples/calc++/test: New.
8499 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
8501 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
8502 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
8503 which stems from the 2005-05-27 patch.
8505 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8507 * data/glr.c: Modify treatment of unused parameters to permit use
8508 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
8510 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
8512 Fix infringement on user name space reported by Janos Zoltan Szabo.
8513 * data/yacc.c (yyparse): strlen -> yystrlen.
8515 2005-05-30 Akim Demaille <akim@epita.fr>
8517 * data/lalr1.cc (_): New.
8518 Translate the various messages.
8520 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8522 Fix infringement on user name space reported by Bruno Haible.
8523 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
8524 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
8525 the user's name space.
8526 (alloca): Include <stdlib.h> to get it, if it's not built in.
8527 (YYMALLOC, YYFREE): Define only if needed.
8528 (malloc, free): Declare, but only if needed, as this infringes on
8529 the user name space.
8531 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8533 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
8534 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
8536 * lib/ebitset.c (min, max): Undef before defining.
8537 * lib/vbitset.c (min, max): Likewise.
8538 * lib/subpipe.c (create_subpipe): Save local variables in case
8539 vfork clobbers them.
8541 2005-05-24 Bruno Haible <bruno@clisp.org>
8543 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
8544 error message syntax used by gcc-4.0.
8546 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
8548 * README: Mention m4 1.4.3. Remove obsolete advice about
8549 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
8551 * bootstrap: Remove workaround for problem I encountered with
8552 gettext 0.14.1; it seems to be fixed now.
8554 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
8556 * NEWS: Version 2.0a.
8558 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
8559 the previous change.
8561 Various maintainer cleanups.
8562 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
8563 conftest*, for benefit of CVS commands run at the same time as
8564 "configure". Add build-aux, since "bootstrap" now creates it and
8566 * Makefile.cfg (move_if_change): Remove.
8567 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
8568 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
8569 (po_repo, do-po-update, po-update, wget_files, get-targets):
8570 (config.guess-url_prefix, config.sub-url_prefix):
8571 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

8573 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
8575 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
8576 this is now the recommended name.
8577 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
8578 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
8579 ylwrap. These files now go into build-aux.
8580 * config/move-if-change: Remove.
8581 * config/prev-version.txt: Bump from 1.75 to 2.0.
8583 * bootstrap: Add stdio-safer, unistd-safer modules.
8584 Remove m4/glibc2.m4 (introduced by latest gnulib, but
8586 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
8587 fopen-safer.c, stdio-safer.h, unistd-safer.h.
8588 * lib/subpipe.c: Include "unistd-safer.h".
8589 (create_subpipe): Make sure all the newly-created
8590 file descriptors are > 2, so that diagnostics don't
8591 get sent down them (which might cause Bison to hang, in theory).
8592 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
8593 * src/files.c (xfopen): Use fopen_safer, not fopen.
8595 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
8596 yesterday's yacc.c fix.
8598 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
8600 * data/glr.c, data/lalr1.cc: Update copyright date.
8602 Fix a destructor bug reported by Wolfgang Spraul in
8603 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8604 * data/yacc.c (yyabortlab): Don't call destructor, and
8605 don't set yychar to EMPTY.
8606 (yyoverflowlab): Don't call destructor.
8607 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8608 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8609 since we no longer output the message "discarding lookahead token
8612 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8614 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8615 fix a small glitch in debugging output.
8616 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8617 after YY_SYMBOL_PRINT where needed.
8619 (struct yyGLRState): Add some comments.
8620 (struct yySemanticOption): Add some comments.
8621 (union yyGLRStackItem): Add comment.
8623 (yymergeOptionSets): Correct this to properly perform the union,
8624 avoiding infinite reported by Michael Rosien.

8668 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8670 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8671 Problem reported by Ralf Menzel.
8673 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8675 * tests/actions.at: Test that stack overflow invokes destructors.
8676 From Marcus Holland-Moritz.
8677 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8679 (yyreturn): to here. That way, destructors are called properly
8680 even if the stack overflows, or the user calls YYACCEPT or
8681 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8682 (yyoverflowlab): Destroy the lookahead.
8684 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8686 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8688 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8690 * NEWS: Bison-generated C parsers no longer quote literal strings
8691 associated with tokens.
8692 * src/output.c (prepare_symbols): Don't escape strings,
8693 since users don't want to see C escapes.
8694 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8696 * tests/input.at (Torturing the Scanner): Likewise.
8697 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8699 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8701 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8702 the data size is known to be too small and we can't increase it.
8703 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8705 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8707 * src/parse-gram.y: Include quotearg.h.
8708 (string_as_id): Quote $1 before using it as a key, since the
8709 lexer no longer quotes it for us.
8710 (string_content): Don't strip quotes, since lexer no longer
8712 * src/scan-gram.l: Include quotearg.h.
8714 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8715 a key, since the rest of the lexer doesn't quote it.
8716 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8717 * tests/regression.at (Token definitions): Check for backslashes
8720 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8721 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8722 (yyparse): Revamp code to generate long syntax error message, to
8723 make it easier to translate, and to avoid problems with arithmetic
8724 overflow. Change "virtual memory" to "memory" in diagnostic, since
8725 we don't know whether the memory is virtual.
8727 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8729 * NEWS: Bison-generated C parsers now use the _ macro to
8731 * data/yacc.c (_) [!defined _]: New macro.
8732 All English strings wrapped inside this macro.
8733 * doc/bison.texinfo (Bison Parser): Document _.
8734 * po/POTFILES.in: Include src/parse-gram.c, since it now
8735 includes translateable strings that parse-gram.y doesn't.
8737 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8739 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8740 reverting the 2004-10-11 change to this function.
8741 (symbol_check_alias_consistency): Don't call symbol_type_set
8742 if the type name is already correct.
8743 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8745 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8747 * tests/regression.at (Token definitions): Don't use a token named
8748 c, as that generates a "#define c ..." that runs afoul of buggy
8749 stdlib.h that uses the identifier c as a member of struct
8750 drand48_data. Problem reported by Horst Wente.
8752 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8754 * bootstrap: Change translation URL from
8755 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8756 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8757 redirection glitches. Problem reported by twlevo@xs4all.nl.
8759 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8761 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8762 after operands; POSIX says this isn't portable for the c99 command.
8764 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8766 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8767 immediately if a data overrun has occurred; this may help us track
8768 down what may be a spurious failure on MacOS.
8770 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8772 Respond to problems reported by twlevo@xs4all.nl.
8774 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8776 * src/vcg.h: Comment fix.
8777 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8778 (G_CMAX): Change to -1 instead of INT_MAX.
8780 * data/yacc.c (yyparse): Omit spaces before #line.
8782 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8784 * src/tables.c (state_number_to_vector_number): Put it inside an
8785 "#if 0", since it's not currently used. Problem reported by
8788 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8790 * src/output.c (escaped_output): Renamed from
8791 escaped_file_name_output, since we now use it for symbol tags as
8792 well. All uses changed.
8793 (symbol_destructors_output, symbol_printers_output):
8794 Escape symbol tags too.
8795 Problem reported by Matyas Forstner in
8796 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8798 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8800 * src/output.c (user_actions_output, token_definitions_output,
8801 symbol_destructors_output, symbol_printers_output): Likewise.
8802 * src/reader.c (prologue_augment): Likewise.
8803 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8805 * src/vcg.c (output_edge): Don't quote linestyle arg.
8806 Problem reported by twlevo@xs4all.nl.
8808 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8810 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8811 example, reported by Derek M Jones. Also, make the example even
8812 more outrageous, to better illustrate how bad the problem is.
8814 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8816 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8817 putsym. Typo reported by Sebastian Piping.
8819 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8821 * doc/bison.texinfo (Language and Grammar): some -> same
8822 (Epilogue): int he -> in the
8823 Typos reported by Sebastian Piping via Justin Pence.
8825 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8827 * tests/glr-regression.at (Improper handling of embedded actions
8828 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8829 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8830 with dollar signs in test names.
8831 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8832 for a similar reason.
8834 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8836 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8837 wants to redefine G_VIEW.
8839 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8841 * src/vcg.c (get_view_str): Remove case for normal_view.
8842 Problem reported by twlevo@xs4all.nl.
8844 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8846 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8847 Problem reported by twlevo@xs4all.nl.
8849 * doc/bison.texinfo: Change @dircategory from "GNU programming
8850 tools" to "Software development". Requested by Richard Stallman
8853 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8855 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8856 Problem reported by twlevo@xs4all.nl.
8858 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8860 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8861 keyword; it's not needed with modern compilers, and it doesn't
8862 affect correctness with older compilers. Suggested by
8865 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8867 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8868 gcc -Wswitch-default.
8869 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
8870 * data/yacc.c (yyparse): Likewise.
8872 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8874 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8875 already. Let config.h define any nonstandard values.
8877 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8879 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8880 for the benefit of slower hosts. Problem reported by
8883 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8885 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8886 being defined and not used.
8887 * data/lalr1.cc (yyparse): Likewise.
8888 Use "if (false)" rather than "if (0)".
8890 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8892 * TODO: Mention that we should allow NUL bytes in tokens.
8894 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8896 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8897 Problem reported by Hans Aberg.
8899 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8901 * src/getargs.c (version): Happy new year; update overall
8902 program copyright date from 2004 to 2005.
8904 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8905 Problem reported by Hans Aberg.
8906 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8907 (Output file names.): Add a test for the case when standard output
8910 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8912 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8913 to fix an oversight in the Bison 2.0 manual.
8915 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8917 * NEWS: Version 2.0. Reformat the existing news items since
8918 1.875, so that related items are grouped together.
8919 * configure.ac (AC_INIT): Bump version to 2.0.
8920 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8922 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8923 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8924 otherwise, we're not testing alloca. Unfortunately there's no
8925 simple way to consult HAVE_ALLOCA here.
8927 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8930 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8931 hand. This avoids a warning about comparing int to size_t when
8932 GCC warnings are enabled.
8934 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8936 * NEWS: Bison-generated parsers no longer default to using the
8937 alloca function (when available) to extend the parser stack, due
8938 to widespread problems in unchecked stack-overflow detection.
8939 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8940 responsibility to set it to a positive value. This lets the user
8941 specify a value that is not a preprocessor constant.
8942 * data/yacc.c (YYMAXDEPTH): Likewise.
8943 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8944 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8945 to be a compile-time constant. However, explain the constraints on it.
8946 Also, explain the constraints on YYINITDEPTH.
8947 (Table of Symbols): Explain that alloca is no longer the default.
8948 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8951 * doc/bison.texinfo (Location Default Action): Mention that n must
8952 be zero when k is zero. Suggested by Frank Heckenbach.
8954 2004-12-22 Akim Demaille <akim@epita.fr>
8956 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8957 (parser::state_type, parser::semantic_type, parser::location_type):
8958 Private, not public.
8959 (parser::parse): Return ints, not bool.
8960 Returning a bool introduces a problem: 0 corresponds to false, and
8961 it seems weird to return false on success. Returning true changes
8962 the conventions for yyparse.
8963 Alternatively we could return void and send an exception.
8964 There is no clear consensus (yet?).
8965 (state_stack, semantic_stack, location_stack): Rename as...
8966 (state_stack_type, semantic_stack_type, location_stack_type): these.
8967 Private, not public.
8968 * tests/c++.at: New.
8969 * tests/testsuite.at, tests/Makefile.am: Adjust.
8971 2004-12-21 Akim Demaille <akim@epita.fr>
8973 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8975 2004-12-21 Akim Demaille <akim@epita.fr>
8977 Don't impose std::string for filenames.
8979 * data/lalr1.cc (b4_filename_type): New.
8980 (position::filename): Use it.
8981 (parser.hh): Move the inclusion of stack.hh and location.hh below
8982 the user code, so that needed headers for the filename type can be
8984 Forward declare them before the user code.
8985 * tests/Makefile.am (check-local, installcheck-local): Pass
8986 TESTSUITEFLAGS to the TESTSUITE.
8988 2004-12-20 Akim Demaille <akim@epita.fr>
8990 Use more STL like names: my_class instead of MyClass.
8992 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8993 (SemanticStack, SemanticType, StateStack, StateType)
8994 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8995 (Parser::value): Rename as...
8996 (location_stack, location_type, rhs_number_type, semantic_stack)
8997 (semantic_type, state_stack, state_type, token_number_type, stack)
8998 (slice, traits, parser::yylloc, parser::yylval): these.
9000 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
9002 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
9004 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
9005 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9007 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
9009 Remove uses of 'short int' and 'unsigned short int'. This raises
9010 some arbitrary limits. It uses more memory but nowadays that's
9011 not much of an issue.
9013 This change does not affect the generated parsers; that's a different
9014 task, as some users will want to conserve memory there.
9016 Ideally we should use size_t to represent all object counts, and
9017 something like ptrdiff_t to represent signed differences of object
9018 counts; but that will require more code-cleanup than I have the
9019 time to do right now.
9021 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9022 Use size_t, not int or short int, to count objects.
9023 * src/closure.c (nritemset, closure): Likewise.
9024 * src/closure.h (nritemset, closure): Likewise.
9025 * src/nullable.c (nullable_compute): Likewise.
9026 * src/print.c (print_core): Likewise.
9027 * src/print_graph.c (print_core): Likewise.
9028 * src/state.c (state_compare, state_hash): Likewise.
9029 * src/state.h (struct state): Likewise.
9030 * src/tables.c (default_goto, goto_actions): Likewise.
9032 * src/gram.h (rule_number, rule): Use int, not short int.
9033 * src/output.c (prepare_rules): Likewise.
9034 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
9035 errs, reductions): Likewise.
9036 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
9038 * src/tables.c (vector_number, tally, action_number,
9039 ACTION_NUMBER_MINIMUM): Likewise.
9040 * src/output.c (muscle_insert_short_int_table): Remove.
9042 2004-12-17 Akim Demaille <akim@epita.fr>
9044 * data/lalr1.cc: Extensive Doxygenation.
9045 (error_): Rename as...
9046 (error): this, since it is visible to the user.
9048 (Parser::message): Now an automatic variable from...
9049 (Parser::yyreport_syntax_error_): here.
9050 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
9052 * tests/input.at: Escape $.
9054 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9056 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9057 Parenthesize rhs to avoid obscure problems with mistakes like
9058 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9059 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9060 b4_rhs_location): Likewise.
9061 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9062 b4_rhs_location): Likewise.
9064 2004-12-16 Akim Demaille <akim@epita.fr>
9066 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
9067 yacc.c: be sure to stay within yycheck_.
9068 * tests/actions.at: Re-enable C++ tests.
9070 2004-12-16 Akim Demaille <akim@epita.fr>
9072 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9075 2004-12-16 Akim Demaille <akim@epita.fr>
9077 Use #define to handle the %name-prefix.
9079 * data/glr.c, data/yacc.c: Comment changes.
9080 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9081 so that one can refer to yylex in the parser file, and have it
9082 renamed, as is the case with other skeletons.
9084 2004-12-16 Akim Demaille <akim@epita.fr>
9086 Move lalr1.cc internals into yy*.
9088 * data/lalr1.cc (semantic_stack_, location_stack_, state_stack_)

9103 (yynerrs_, yylooka_, yyilooka_, yyerror_range_, yynerrs_):
9106 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
9108 Fix some problems reported by twlevo at xs4all.
9109 * src/symtab.c (symbol_new): Report an error if the input grammar
9110 contains too many symbols. This is better than calling abort() later.
9111 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
9112 (struct node, struct graph):
9113 Rename member expand to stretch. All uses changed.
9114 (struct graph): Remove member layoutalgorithm. All uses removed.
9115 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
9116 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
9118 (N_STRETCH): Rename from N_EXPAND. All uses changed.
9120 2004-12-15 Akim Demaille <akim@epita.fr>
9122 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
9123 Add more Doxygen comments.
9124 (symprint_, stack_print_, reduce_print_, destruct_, pop)
9125 (report_syntax_error_, translate_): Rename as...
9126 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
9127 (yypop_, yyreport_syntax_error_, yytranslate_): this.
9129 2004-12-15 Akim Demaille <akim@epita.fr>
9131 * data/lalr1.cc (lex_): Rename as...
9133 Move the trace here.
9134 Take the %name-prefix into account.
9135 Reported by Alexandre Duret-Lutz.
9137 2004-12-15 Akim Demaille <akim@epita.fr>
9139 Simplify the C++ parser constructor.
9141 * data/lalr1.cc (debug_): Rename as...
9142 (yydebug_): so that the parser's internals are always in the yy*
9145 (b4_parse_param_decl): Remove the leading comma as it is now only
9146 called as unique argument list.
9147 (Parser::Parser): Remove the constructor accepting a location and
9148 an initial debugging level.
9149 Remove from the other ctor the argument for the debugging level.
9150 (debug_level_type, debug_level, set_debug_level): New.
9152 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
9155 2004-12-15 Akim Demaille <akim@epita.fr>
9157 Remove b4_root related material: failure experiment
9158 (which goal was to allow to derive from a class).
9160 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
9161 definitions and uses.
9163 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
9165 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
9166 not 2, since it's not portable to subtract 1 from the start of an
9167 array. The new item 0 is never set or used. All uses changed.
9169 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
9170 the default definition of YYLLOC_DEFAULT. Problem reported
9171 by Frank Heckenbach.
9173 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
9175 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
9176 the normal case and one for the error case. Just use the
9177 first one uniformly. Problem reported by Frank Heckenbach.
9178 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9179 use exactly the same macro in both places.
9180 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9181 so that the normal-case YYRHSLOC works for the error case too.
9183 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
9184 (YYLLOC_DEFAULT): Use the same macro as glr.c.
9185 * doc/bison.texinfo (Location Default Action): Don't claim that
9186 we have an array of locations. Use the same macro for both glr
9187 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9190 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9192 * HACKING: Update email addresses to send announcements to.
9194 * configure.ac (AC_INIT): Bump version to 1.875f.
9196 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9198 * NEWS: Version 1.875e.
9199 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
9201 * src/scan-skel.l: Include "complain.h", for "fatal".
9203 * src/relation.h (relation_print, relation_digraph):
9204 Relation sizes are of type relation_node, not size_t (this is
9205 merely a doc fix, since the two types are equivalent).
9206 (relation_transpose): Relation sizes are of type relation_node,
9208 * src/relation.c: Likewise.
9209 (top, infinity): Now of type relation_node, not int.
9210 (traverse, relation_transpose): Use relation_node, not int.
9212 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9213 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9214 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9216 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9217 specifying whether the test should be skipped. Use it tp
9218 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9219 fail on some hosts, and should be skipped.
9221 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9223 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9224 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9225 unless otherwise specified below.
9227 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9228 to allocate kernel_base, kernel_items, kernel_size, since
9229 they needn't be initialized to 0.
9230 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9231 * src/closure.c (new_closure): Likewise, for itemset.
9232 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
9233 * src/lalr.c (set_goto_map): Likewise, for temp_map.
9234 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
9235 (build_relations): Likewise for edge, states1, includes.
9236 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
9237 * src/reader.c (packgram): Likewise, for ritem, rules.
9238 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
9239 * src/relation.c (relation_digraph): Likewise for VERTICES.
9240 (relation_transpose): Likewise for new_R, end_R.
9241 * src/symtab.c (symbols_token_translations_init): Likewise for
9243 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
9244 (token_actions): Likewise for yydefact, actrow, conflrow,
9246 (save_column): Likewise for froms[symno], tos[symno].
9247 (goto_actions): Likewise for state_count.
9248 (pack_table): Likewise for base, pos, check.
9249 (tables_generate): Likewise for width.
9251 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9252 for initial core. Just have a separate core, so we needn't worry
9253 about whether kernel_size and kernel_base are initialized.
9255 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9256 kernel_size, kernel_items): Remove unnecessary initialization.
9257 * src/conflicts.c (conflicts): Likewise.
9258 * src/derives.c (derives): Likewise.
9259 * src/muscle_tablc (muscle_insert): Likewise.

9261 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
9262 conflrow, conflict_table, conflict_list, table, check):
9265 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9266 This is because all callers pass unsigned int.
9267 * src/closure.h (new_closure): Likewise.
9269 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9270 (build_relations): Initialize includes[i] in all cases.
9271 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9272 and rules[ruleno].precsym. Initialize members in order.
9273 * src/relation.c (relation_transpose): Always initialize new_R[i]
9275 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9277 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9278 conflict_list[0] was always 0, but now it isn't initialized.
9280 * src/table.c (table_grow): When conflict_table grew, the grown
9281 area wasn't cleared. Fix this.
9283 * lib/.cvsignore: Add strdup.c, strdup.h.
9284 * m4/.cvsignore: Add strdup.m4.
9286 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9288 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9289 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9290 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9291 ngotos + 1 without checking for overflow.
9292 (build_relations): Use END_NODE, not -1, to denote end of edges.
9293 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9294 build_relations): Use goto_number, not int, for goto numbers.
9295 * src/tables.c (save_column, default_goto): Likewise.
9297 2004-11-23 Akim Demaille <akim@epita.fr>
9299 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9300 of #defining from yystype.
9301 Don't typedef yystype, C++ does not need it.
9302 This lets it possible to forward declare it as union.
9304 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9306 * bootstrap (gnulib_modules): Add extensions.
9307 Problem reported by Jim Meyering.
9309 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
9311 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9312 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
9313 src/system.h, src/tables.c: XFREE -> free, to accommodate
9314 recent change to gnulib xalloc.h.
9315 Problem reported by Jim Meyering.
9317 2004-11-17 Akim Demaille <akim@epita.fr>
9319 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
9321 2004-11-17 Akim Demaille <akim@epita.fr>,
9322 Alexandre Duret-Lutz <adl@gnu.org>
9324 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
9327 Use it instead of cdebug_.
9328 (Parser::debug_stream, Parser::set_debug_stream): New.
9329 (Parser::symprint_): Define cdebug_ for temporary backward
9331 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
9334 2004-11-17 Akim Demaille <akim@epita.fr>
9336 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
9337 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
9338 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
9339 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
9341 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
9343 * data/glr.c (yyloc_default): Remove; not used.
9344 Problem reported by Frank Heckenbach.
9346 2004-10-25 Akim Demaille <akim@epita.fr>
9348 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
9349 Introduce another definition to address simple location arrays.
9350 (yyGLRStack): New member: yyerror_range.
9351 (yyrecoverSyntaxError, yyparse): Update it.
9352 (yyrecoverSyntaxError): Use it when shifting the error token to
9353 have an accurate range, equivalent to the one computed by both
9354 yacc.c and lalr1.cc.
9355 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
9356 that column numbers start at column 0, as per GNU Coding
9357 Standards, the others tests, and the doc.
9358 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
9359 Adjust to the above change (first column is 0).
9360 And adjust the location of the "<error>", now covering the whole
9363 2004-10-22 Akim Demaille <akim@epita.fr>
9364 and Paul Eggert <eggert@cs.ucla.edu>
9366 Remove some arbitrary limits on goto numbers and relations.
9367 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9368 initial values, since they're never used.
9369 (set_goto_map): ngotos is now unsigned, so test for overflow
9370 by seeing whether it wraps around to zero.
9371 * src/lalr.h (goto_number): Now size_t, not short int.
9372 (GOTO_NUMBER_MAXIMUM): Remove.
9373 * src/relation.c (relation_print, traverse, relation_transpose):
9374 Check for END_NODE rather than looking at sign.
9375 * src/relation.h (END_NODE): New macro.
9376 (relation_node): Now size_t, not short int.
9378 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9380 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9381 keyword, not an identifier. Problem reported by Baron Schwartz in
9382 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9384 2004-10-11 Akim Demaille <akim@epita.fr>
9386 * src/symtab.c (symbol_check_alias_consistency): Also check
9387 type names, destructors, and printers.
9388 Reported by Alexandre Duret-Lutz.
9389 Recode the handling of associativity and precedence in terms
9390 of symbol_precedence_set.
9391 Accept no redeclaration at all, not even equal to the previous
9393 (redeclaration): New.
9394 Use it to factor redeclaration complaints.
9395 (symbol_make_alias): Don't set the type of the alias, let
9396 symbol_check_alias_consistency do it as for other features.
9397 * src/symtab.h (symbol): Add new member prec_location, and
9399 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
9400 * tests/input.at (Incompatible Aliases): New.
9402 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9404 .cvsignore fixes to accommodate gnulib changes,
9405 and the practice of naming build directories "_build".
9406 * .cvsignore: Add "_*". Sort.
9407 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9408 * m4/.cvsignore: Add "*_gl.m4".
9410 2004-10-06 Akim Demaille <akim@epita.fr>
9412 * src/parse-gram.y (add_param): Fix the truncation of trailing
9415 2004-10-05 Akim Demaille <akim@epita.fr>
9417 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9418 whether the reducion was empty or not. This leaves room to
9419 improve the use of YYLLOC_DEFAULT in such a case.
9420 lalr1.cc is still experimental, so changing this is acceptable.
9421 And finally, there are probably not many users who changed the
9422 handling of locations in GLR, so changing is admissible too.
9424 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9425 empty reduction, set @$ to an empty location ending the previously
9427 Adjust uses to make sure the code is triggered on empty
9429 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
9430 expected output: empty reductions have empty locations.
9432 2004-09-29 Akim Demaille <akim@epita.fr>
9434 * data/lalr1.cc: Move towards a more standard C++ coding style
9435 for templates: Class < T > -> Class<T>.
9437 2004-09-29 Akim Demaille <akim@epita.fr>
9439 * data/lalr1.cc: Reinstall the former ctor, for sake of
9440 compatibility, but warn it will be removed.
9441 Move towards a more standard C++ coding style (i.e., type *var ->
9444 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
9446 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
9447 since it's less likely to work if NULs are involved in the future.
9449 2004-09-27 Akim Demaille <akim@epita.fr>
9451 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
9453 2004-09-27 Akim Demaille <akim@epita.fr>
9455 * data/lalr1.cc (b4_parse_param_decl_1): New.
9456 (b4_parse_param_decl): Use it to have different names between attribute
9458 (b4_cc_constructor_call): Likewise.
9460 2004-09-24 Akim Demaille <akim@epita.fr>
9462 * src/parse-gram.y (add_param): Strip the leading and trailing
9463 blanks from a formal argument declaration.
9464 (YY_LOCATION_PRINT): New.
9466 2004-09-24 Akim Demaille <akim@epita.fr>
9468 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
9471 2004-09-24 Akim Demaille <akim@epita.fr>
9473 * doc/bison.texinfo (Table of Symbols): Sort.
9475 2004-09-21 Akim Demaille <akim@epita.fr>
9477 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
9478 the useless parentheses.
9479 Suggested by Paul Eggert.
9481 2004-09-20 Akim Demaille <akim@epita.fr>
9483 Let the initial-action act on the look-ahead, and use it for the
9484 "initial push" (corresponding to an hypothetical beginning-of-file).
9485 And let lalr1.cc honor %initial-action.
9487 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
9489 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
9490 (Parser::Parser): Remove the ctor that used to initialize it.
9491 (Parser::parse): Like in the other skeletons, issue the "starting
9492 parse" message before any action.
9493 Honor %initial-action.
9494 Initialize the stacks with the lookahead.
9495 * data/yacc.c: Let $$ and @$ in %initial-action designate the
9497 Push them in the stacks.
9498 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
9500 2004-09-20 Akim Demaille <akim@epita.fr>
9502 * doc/bison.texinfo (Initial Action Decl): New.
9504 2004-09-20 Akim Demaille <akim@epita.fr>
9506 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
9507 clearer criterion to define it.
9508 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
9509 When reducing on an empty RHS, use the latest stacked location as
9511 yylloc is not always available.
9512 * data/glr.c: Likewise.
9513 Also, honor initial-actions.
9515 2004-09-20 Akim Demaille <akim@epita.fr>
9517 * data/yacc.c (YY_LOCATION_PRINT): New.
9518 Define when we know YYLTYPE's structure, i.e., when the default
9519 YYLLOC_DEFAULT is used.
9520 * data/c.m4 (b4_yysymprint_generate): Use it.
9521 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
9522 value of the result.
9523 (error_start_): Replace with...
9524 (error_range_): this location array.
9525 This allows to replace code relying on the implementation of
9526 locations by portable code.
9527 * data/yacc.c (yylerrsp): Replace with...
9528 (yyerror_range): this.
9529 Every time a token is popped, update yyerror_range[0], to have an
9530 accurate location for the error token.
9531 * data/glr.c (YY_LOCATION_PRINT): New.
9532 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
9533 deference a pointer.
9534 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
9535 report the location in %printers.
9537 * src/scan-skel.l: Instead of abort, report error messages to ease
9538 understanding skeleton scanning failures.
9540 2004-09-16 Akim Demaille <akim@epita.fr>
9542 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
9543 (iterator, const_iterator): these, to be more in the C++ spirit.
9544 Also, return reverse iterators so that when displaying the stack
9545 we display its bottom first.
9546 (Parser::stack_print_, Parser::reduce_print_): Match the messages
9548 We should probably use vector here though.
9550 2004-09-16 Akim Demaille <akim@epita.fr>
9552 Have more complete shift traces.
9554 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
9555 to report Shifts instead of ad hoc YYDPRINTF invocations,
9556 including for the error token.
9557 * data/lalr1.cc (symprint_): Output the location.
9558 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9559 output the location within the %printer.
9560 Activate GLR tests, at least to make sure they compile properly.
9561 They still don't pass though.
9562 * tests/calc.at: Adjust expect verbose output, since now "Entering
9563 state..." is on a different line than the "Shifting" message.
9565 2004-09-08 Akim Demaille <akim@epita.fr>
9567 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9568 Bison directive from the Bison file to the invocation of this
9569 macro, so that these directives are passed to
9570 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9571 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9572 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9573 the extra Bison directives instead of the whole series.
9574 Change the grammar so that there are recoverable errors, and
9575 unrecoverable errors. Now we can have the parser give up before
9576 consuming the whole input. As a result we now can observe that
9577 the lookahead is freed when needed.
9578 Change the parser source to parse argv[1] instead of a hard coded
9580 Simplify yylex, and give a value and location to EOF.
9581 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9582 passed directives already coded in the file.
9583 Add some tests to check the location of "error".
9584 For some tests, the C++ parser is correct, and not yacc.c.
9585 For other tests, they provide different, but unsatisfying, values,
9586 so keep the C++ value so that at least one parser is "correct"
9587 according to the test suite.
9588 (Actions after errors): Remove, this is subsumed by the
9589 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
9591 2004-09-06 Akim Demaille <akim@epita.fr>
9593 * data/lalr1.cc: Adjust the indentation of the labels.
9597 2004-09-06 Akim Demaille <akim@epita.fr>
9599 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9600 argument, an informative message.
9601 Call YY_SYMBOL_PRINT.
9602 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9603 * data/lalr1.cc (destruct_): Likewise.
9604 In addition, no longer depend on b4_yysymprint_generate and
9605 b4_yydestruct_generate to generate these functions, do it "by
9608 2004-09-03 Akim Demaille <akim@epita.fr>
9610 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9611 invoked, yydestruct the lookahead.
9612 * tests/calc.at (Calculator $1): Update the expected lengths of
9613 traces: there is an added line for the discarded lookahead.
9614 * doc/bison.texinfo (Destructor Decl): Some rewording.
9615 Define "discarded" symbols.
9617 2004-09-02 Akim Demaille <akim@epita.fr>
9619 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9621 2004-09-02 Akim Demaille <akim@epita.fr>
9623 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9624 (YYDSYMPRINTF): Rename as...
9625 (YY_SYMBOL_PRINT): this.
9626 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9628 Use it instead of direct symprint_ calls.
9629 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9632 2004-09-02 Akim Demaille <akim@epita.fr>
9634 * data/lalr1.cc (b4_yysymprint_generate): New.
9635 (symprint_): New member function, defined when YYDEBUG.
9636 Use it consistently instead of token/nterm debugging output by
9638 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9639 %printer calls to use cdebug_ when using lalr1.cc.
9641 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9643 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9644 with #ifdef YYDEBUG.
9646 2004-08-26 Akim Demaille <akim@epita.fr>
9648 * doc/bison.texinfo (Implementing Loops): Rename as...
9649 (Implementing Gotos/Loops): this.
9651 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9653 Adjust to latest gnulib.
9654 * bootstrap (gnulib_modules): Add xalloc-die.
9655 Set LC_ALL=C so that file names sort consistently.
9656 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9657 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9658 uintmax_t.m4, ulonglong.m4.
9659 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9660 po.m4 since we are now using _gl.m4 instead.
9662 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9664 * src/scan-action.l: Remove. Scanning of semantic actions is
9665 handled in scan-gram.l.
9667 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9669 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9671 * src/location.h (struct): The file member is a uniqstr.
9672 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9674 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9676 Fix bug with non-%union parsers that have printers or destructors,
9677 which led to a Bison core dump. Reported by Peter Fales in
9678 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9680 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9681 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9682 not to our own type.
9683 * src/output.c (symbol_destructors_output, symbol_printers_output):
9684 Don't assume %union.
9685 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9686 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9687 UNION-FLAG. All callers changed.
9688 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9689 Use type char, not unsigned int, when declaring an array of char;
9690 this lets us remove a cast.
9691 (Printers and Destructors): Add non-%union test cases.
9693 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9695 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9696 GLR writeups. E.g., avoid frenchspacing and the future tense,
9697 change "lookahead" to "look-ahead", and change "wrt" to "with
9700 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9702 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9703 New sections, split off from the GLR Parsers section. Put the new
9704 Simple GLR Parser near the start of the GLR section, for clarity.
9705 Rewrite connective text.
9707 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
9709 * doc/bison.texinfo (Simple GLR Parsers): New section.
9711 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9713 * NEWS, TODO, doc/bison.texinfo:
9714 Use "look-ahead" instead of "lookahead", to be consistent.

9738 * README: Update location of patched M4 distribution.
9740 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
9742 Don't assume the C++ compiler takes the same arguments as the C compiler
9744 * configure.ac (O0CXXFLAGS): New var.
9745 * tests/atlocal.in (CXXFLAGS): Use it.
9747 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
9749 Fix some "make check" problems with C++ reported by
9750 Albert Chin-A-Young for Tru64 C++ in this thread:
9751 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
9753 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
9754 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9755 Output to a .cc file for C++, not to a .c file.
9756 * tests/calc.at (AT_CHECK_CALC): Likewise.
9757 * tests/regression.at (AT_CHECK_DANCER): Likewise.
9758 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
9760 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
9762 * tests/calc.at, tests/actions.at: Workaround for SGI
9763 C++ compiler. (trivial change)
9765 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9767 Spent a few hours checking out which prerequisite versions the
9768 current sources actually require. I went all the way back to
9769 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9770 a seemingly endless set of combinations of versions more recent
9771 than that. The bottom line is that the current sources require
9772 fairly recent versions of the build tools, and it'll be some work
9774 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9775 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9776 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9777 Add comments explaining why those particular versions are
9780 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9781 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9782 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9784 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9785 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9787 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9789 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9790 0.11.5. Suggested by Bruno Haible.
9791 * bootstrap: Remove gettext version checking.
9793 * doc/bison.texinfo (Decl Summary): Also mention that %union
9794 can depend on prerequisite types. Problem reported by Tim
9797 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9799 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9800 * README-alpha: Don't tell people not to package this.
9802 * bootstrap: Don't assume $(...) works; use `...` instead.
9803 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9806 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9807 put into the -d output file, and mention what to do if YYSTYPE is
9810 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9812 Undo change made earlier today: it caused autopoint to not bring
9813 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9816 * bootstrap: Check that gettext version matches what's in
9817 configure.ac. Warn users to ignore robots.txt ERROR 404.
9818 * bootstrap: Undo today's earlier change (logged below).
9819 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9821 The gettext version checking is causing more trouble than it's
9822 curing; remove it. Problem reported by Paul Hilfinger.
9824 * bootstrap: Issue a warning that one can expect a message
9825 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9826 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9828 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9830 Ensure that the C++ compiler used for testing actually works on a
9831 simple test program; if not, skip the C++-related tests. Problem
9832 reported by Vin Shelton in:
9833 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
9835 * m4/cxx.m4: New file.

9840 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9842 * data/glr.c (yylloc): Output this macro even if locations are not
9843 being generated, as the GLR parser needs it even in that case.
9844 Problem reported by Troy A. Johnson
9845 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
9847 * configure.ac (AC_INIT): Update to 1.875e.

9855 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
9856 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9857 lalr1.cc runs afoul of the first, and the last two are no longer
9858 supported by GCC 3.4.0.
9859 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9860 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9862 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
9864 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
9865 unsigned int, for compatibility with latest gnulib hash module.

9867 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
9868 * src/uniqstr.c (hash_uniqstr): Likewise.
9870 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>

9875 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
9876 character and string literals.
9877 (unexpected_end): New function.

9886 Fix typo by replacing $1 with $option.
9887 Remove more 'intl'-related files.
9888 Don't DEFUN AM_INTL_SUBDIR twice.
9890 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
9891 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
9893 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
9894 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,

9896 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
9897 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
9898 * src/.cvsignore: Add *.output.
9900 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9901 gets copied to the output file.
9903 2004-04-28 Paul Eggert <eggert@twinsun.com>
9905 Get files from the gnulib and po repositories, instead of relying
9906 on them being in our CVS. Upgrade to latest versions of gnulib
9909 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9910 * bootstrap: Bootstrap from gnulib and po repositories.
9911 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9912 * README-cvs: Document these changes. Remove version numbers from
9913 mentions of build tools, since they change so often. Mention Flex.
9915 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.

9917 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
9918 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9920 (AC_ISC_POSIX): Remove; we no longer support this
9921 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9922 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9923 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9924 Do not check for C89 headers, except for locale.h which is used
9925 by the Yacc library and must port to K&R hosts.
9926 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
9927 Do not check for C89 functions, except for setlocale which is
9928 used by the Yacc library.

9933 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
9934 AM_GNU_GETTEXT): Remove; now done by:
9935 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.

9939 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9940 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
9941 Define to empty, as gnulib.mk will do the rest for us.
9942 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
9944 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
9945 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
9947 * src/files.c: Include gnulib's xstrndup.h.

9950 (REALLOC): Use xnrealloc, for likewise.
9951 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
9952 (strnlen, memrchr): Remove decls; functions no longer used.

9975 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
9976 Remove, as these files are now generated automatically
9977 by bootstrap or automake.
9979 * po/ChangeLog: Remove: all but one entry was a duplicate
9980 of this file, and I moved that 2000-11-02 entry here.
9982 * config/.cvsignore: Add Makefile, depcomp, install-sh.
9983 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

9999 * src/.cvsignore: Remove *_.c.
10002 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
10003 support it. (The latest stable gzip doesn't.)
10005 2004-04-27 Paul Eggert <eggert@twinsun.com>
10007 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10008 case, as stos_ is now used by destructors due to the 2004-02-09
10011 Remove more K&R C support.
10012 * lib/libiberty.y (PARAMS): Remove. All uses removed.
10013 * lib/subpipe.c (errno): Remove decl.
10014 Include <stdlib.h> unconditionally.
10015 (EXIT_FAILURE): Remove macro.
10016 * src/complain.c (vfprintf, strerror): Remove.
10017 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h

10021 (strchr, strspn, memchr): Remove decls.
10022 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
10023 unconditionally. Do not declare perror.
10024 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
10027 * src/complain.c (_): Remove useless defn, as system.h defines this.
10029 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
10030 with latest obstack.h.
10031 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
10032 to procedure types, as obstack.h now does that for us.
10033 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
10035 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10036 so that this include file can stand alone.
10037 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10038 does this now. Include subpipe.h first after config.h, to
10039 test whether it can stand alone.
10041 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10042 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10043 unused declaration.
10045 * tests/synclines.at (%union synch line): Put a dummy member in
10046 the union, because empty unions aren't allowed in C. Caught
10049 2004-04-13 Jim Meyering <jim@meyering.net>
10051 * src/conflicts.c (conflicts_print): Correct format string typo:

10054 2004-03-30 Paul Eggert <eggert@twinsun.com>
10056 * src/getargs.c (version): Update copyright year to 2004.

10117 2004-03-08 Paul Eggert <eggert@gnu.org>
10119 Add support for hex token numbers. Suggested by Odd Arild Olsen in
10120 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
10122 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
10124 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
10125 * src/scan-gram.l (scan_integer): New function.
10127 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
10128 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,

10130 Say "long int", not "long", for uniformity with GNU style.
10132 2004-02-25 Paul Eggert <eggert@twinsun.com>
10134 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
10135 compilers. This fixes a problem with Intel's C++ compiler being
10136 chatty, reported by Guido Trentalancia in
10137 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
10139 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
10141 Support %destructor and merge error locations in lalr1.cc.
10143 * data/lalr1.cc (b4_cxx_destruct_def): New macro.

10149 token which are discarded.
10150 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
10151 error_start_ when erroneous token are discarded.
10152 (Parser::parse) <yyerrlab1>: Compute the location of the error
10153 token so that it covers all the discarded tokens.
10154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
10155 it can be called with `%skeleton "lalr1.cc"', and do that.
10157 2004-02-02 Paul Eggert <eggert@twinsun.com>
10159 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
10160 $(top_srcdir)/lib and ../lib. This fixes a bug reported
10161 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10162 There's no need to mention top_builddir since Automake does that
10164 (INCLUDES): Remove, as Automake says it's obsolescent.
10165 Contents migrated into AM_CPPFLAGS as described above.
10166 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
10168 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>

10181 * config/depcomp, config/install-sh: Sync with Automake 1.8.
10182 * src/output.c (output_skeleton): Rename local var.
10183 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
10184 Bison tokens, as this runs afoul of the 2003-10-07 change that
10185 disallowed NUL bytes in character constants or string literals.
10187 * tests/local.at: Require Autoconf 2.59's Autotest.
10188 * tests/testsuite.at: Don't include local.at, since we now assume
10189 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
10191 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
10192 multiple inclusion warnings.

10206 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
10207 if testsuite doesn't exist.
10209 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
10210 literals, unfortunately.

10214 2003-10-05 Paul Eggert <eggert@twinsun.com>
10216 * NEWS: Don't document %no-default-prec, as it's still
10218 * doc/bison.texinfo: Document %no-default-prec only if

10221 2003-10-04 Paul Eggert <eggert@twinsun.com>
10223 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10224 non-modifiable lvalue, instead of a modifiable one.
10225 * doc/bison.texinfo (Actions): Document that $$ can
10226 be assigned to. Do not claim that $$ and $N are
10227 array element references: user code should not rely on this.

10265 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify

10287 2003-08-25 Akim Demaille <akim@epita.fr>
10289 When reducing initial empty rules, Bison parser read an initial
10290 location that is not defined. This results in garbage, and that
10291 affects Bison's own parser. Therefore we need (i) to extend Bison
10292 to support a means to initialize this location, and (ii) to use
10293 this CVS Bison to fix CVS Bison's parser.
10295 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10297 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10298 * src/parse-gram.y: Adjust.
10299 (%initial-action): New.
10300 (%error-verbose): Since we require CVS Bison, there is no reason
10302 * src/scan-gram.l: Adjust.
10303 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10304 * data/yacc.c (yyparse): Use b4_initial_action.
10306 2003-08-25 Akim Demaille <akim@epita.fr>
10308 * doc/bison.texinfo: Don't promote stdout for error messages.

10331 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10332 error recovery loops. This patch is based on
10333 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10334 Also, augment the similarity between lalr1.cc and yacc.c.
10335 Note: the locations of error recovery rules are not correct yet.
10337 * data/lalr1.cc: Comment changes to augment the similarity between
10338 lalr1.cc and yacc.c.
10339 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
10340 (yyerrlab1): Remove, but where it used to be (now the bottom part of
10341 yyerrlab), when hitting EOF, pop the whole stack here instead of
10342 merely falling thru the default error handling mechanism.
10343 (yyerrorlab): New label, with the old contents of YYERROR,
10344 plus the following change: pop the stack of rhs corresponding
10345 to the production that invoked YYERROR. That is how Yacc
10346 behaves (required by POSIX).
10347 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
10350 2003-08-25 Akim Demaille <akim@epita.fr>
10352 Tune local.at so that people can "autom4te -l autotest calc.at -o
10353 calc" for instance, to extract a sub test suite.
10355 * tests/testsuite.at: Move the initialization, Autotest version
10356 requirement, and AT_TESTED invocation into...
10357 * tests/local.at: here.
10358 * tests/testsuite.at: Include it for compatibility with Autoconf
10360 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
10363 2003-08-04 Paul Eggert <eggert@twinsun.com>
10365 Rework code slightly to avoid gcc -Wtraditional warnings.
10366 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10367 The returned value is now stored in *YY0. All callers changed.
10368 * src/output.c (merge_output): Adjust to the above change.
10370 2003-07-26 Paul Eggert <eggert@twinsun.com>
10372 * data/glr.c (YYASSERT): New macro.
10373 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10374 yyresolveStates, yyprocessOneStack):
10375 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10376 Derived from a suggestion by Frank Heckenbach.
10378 2003-07-25 Paul Eggert <eggert@twinsun.com>
10380 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10381 for portability to K&R C (after ansi2knr, presumably). See
10382 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10383 by Frank Heckenbach, though I have omitted the structure-initialization
10384 part of his glr-knr.diff patch since I recall that the Portable
10385 C Compiler didn't require that change.
10387 Let the user specify how to allocate and free memory.
10388 Derived from a suggestion by Frank Heckenbach in
10389 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
10390 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10391 All uses of free, malloc, realloc changed to use these macros,
10392 and unnecessary casts removed.
10393 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10395 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10397 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10398 use s.empty() rather than s == "" to test for empty string; see
10399 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>

10411 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10412 Remove unnecessary parentheses from uses.

10418 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10419 yyreportTree): Do not assume that size_t is the same width as int,
10420 when printing sizes. Print sizes using an unsigned format.
10421 Problem reported by Frank Heckenbach in
10422 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10424 Port to Forte Developer 7 C compiler.
10425 * data/glr.c (struct YYLTYPE): If locations are not being used,
10426 declare a single dummy member, as empty structs do not conform
10428 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
10429 the Forte Developer 7 C compiler complains that end-of-loop
10430 code is not reached.

10445 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
10446 Don't use 'index' in comments, as it's a builtin fn on some hosts.

10474 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
10475 `How Can I Reset @code{yyparse}', since texinfo does not allow
10476 arbitrary @ in node names.
10478 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
10479 shouldn't be needed according to the gettext 0.12.1 documentation
10480 but which seem to be needed anyway: codeset.m4 glibc21.m4
10481 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

10503 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
10504 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
10505 the tests right now.
10506 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
10507 yyerror are declared before use; C99 requires this.
10509 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10511 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
10513 (yyrecoverSyntaxError): Correct the logic for setting and testing
10515 Correct comment on handling EOF.
10516 Allow states with only a default reduction, rather than failing
10517 (I can't quite reconstruct why these were not allowed before).
10519 Fixes to avoid problem that $-N rules in GLR parsers can cause
10520 buffer overruns, corrupting state.
10522 * src/output.c (prepare_rules): Output max_left_semantic_context
10524 * src/reader.h (max_left_semantic_context): New variable declaration.

10536 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
10537 locations not used.

10539 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
10541 * tests/cxx-type.at: Exercise location information; update tests
10542 to differentiate output with and without locations.
10543 Remove forward declarations of yylex and yyerror---caused errors
10544 because default YYLTYPE not yet defined.
10545 Change semantic actions to compute strings, rather than printing
10546 them directly (to test proper passing of semantics values). Change
10547 output to prefix notation and update test data and expected results.
10548 (yylex): Track locations.
10549 (stmtMerge): Return value rather than printing, and include arguments
10552 2003-06-03 Paul Eggert <eggert@twinsun.com>
10554 Avoid warnings generated by GCC 2.95.4 when Bison is
10555 configured with --enable-gcc-warnings.
10556 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,

10562 Rename local vars to avoid warnings.
10563 * tests/glr-regression.at (Improper handling of embedded actions
10564 and $-N in GLR parsers): Remove unused local variable from yylex.
10565 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
10566 (void) as arg when not pure, since we now assume C89 when building
10567 Bison. Pacify GCC by using parameter.
10569 2003-06-02 Paul Eggert <eggert@twinsun.com>
10571 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
10572 yy::Location::lines, yy::Location::columns): Rename arguments
10573 to avoid shadowing; this removes a warning generated by GCC 3.3.
10575 2003-06-01 Paul Eggert <eggert@twinsun.com>
10577 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
10578 to g++, as GCC 3.3 complains if you do it.
10579 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
10580 everything that WARNING_CFLAGS has, except omit warnings
10581 not suitable for C++.
10582 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
10583 * tests/atlocal.in (CXXFLAGS): New var.
10584 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
10586 Fix a GLR parser bug I reported in February; see
10587 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
10588 The problem was that GLR parsers did not conform to the C standard,
10589 because actions like { $1 = $2 + $3; } expanded to expressions
10590 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10591 to a local variable. The C standard says that expressions
10592 like (var = f ()) + (var = f ()) have undefined behavior.
10593 Another problem was that GCC sometimes issues warnings that
10594 yyfill and its parameters are unused.
10596 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10597 as possibly unused.
10598 (yyfill): New function.
10600 (yyuserAction): Change type of yynormal to bool, so that it matches
10601 the new yyfill signature. Mark it as possibly unused.
10604 Follow up on a bug I reported in February, where a Bison-generated
10605 parser can loop. Provide a test case and a fix for yacc.c. I
10606 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10607 The original bug report is in:
10608 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10610 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10611 macro's size was becoming unwieldy.
10612 (yyerrlab): Do not discard an empty lookahead symbol, as this
10613 might destroy garbage.
10614 (yyerrorlab): New label, with the old contents of YYERROR,
10615 plus the following change: pop the stack of rhs corresponding
10616 to the production that invoked YYERROR. That is how Yacc
10617 behaves, and POSIX requires this behavior.
10618 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10619 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10620 Define 'alarm' to do nothing if unistd.h is not available.
10621 Add a new rule "exp: '-' error;" to test the above change to
10622 data/yacc.c. Use 'alarm' to abort any test taking longer than
10623 10 seconds, as it's probably looping.
10624 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10625 Also, the new yacc.c generates two fewer diagnostics for an
10628 2003-05-24 Paul Eggert <eggert@twinsun.com>
10630 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10631 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10632 This fixes a problem reported by John Bowman when the Compaq/HP
10633 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10634 -ansi -Wall -gall).
10635 * data/yacc.c (union yyalloc): Likewise.
10636 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10638 Switch from 'int' to 'bool' where that makes sense.

10643 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10644 Return or accept bool, not int. All callers changed.
10645 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
10646 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

10648 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
10649 bitset_or_and_cmp_): Likewise.
10650 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
10651 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,

10663 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10664 lbitset_xor_cmp): Likewise.
10665 * lib/bbitset.h: Include <stdbool.h>.
10666 (struct bitset_vtable): The following members now return bool, not
10667 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10668 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10670 * src/conflicts.c (count_rr_conflicts): Likewise.
10671 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.

10691 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
10692 * src/output.c (prepare): Use it.
10693 * src/output.c (token_definitions_output,
10694 symbol_destructors_output, symbol_destructors_output): Use string,
10695 not boolean integer, to keep track of whether to output separator.
10696 * src/print_graph.c (print_core): Likewise.
10697 * src/state.c (state_rule_lookaheads_print): Likewise.
10699 * config/install-sh: Sync from automake 1.7.5.
10701 2003-05-14 Paul Eggert <eggert@twinsun.com>
10703 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10704 semicolon after a grammar declaration, in the interest of possible
10705 future changes to the Bison input language.
10706 Do not allow a stray semicolon at the start of the grammar.
10707 (rhses.1): Allow one or more semicolons after any rule, including
10708 just before "|" as required by POSIX.
10709 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10712 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10714 %parse-param support for lalr1.cc.
10716 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10717 b4_cc_constructor_calls, b4_cc_constructor_call,
10718 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10720 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10721 parse-param arguments.
10722 (yy::b4_parser_class_name): Declare instance variables to
10723 hold parse-param arguments.
10724 * tests/calc.at: s/value/semantic_value/ because value clashes
10725 with a member of yy::b4_parser_class_name. Adjust C++ code
10726 to handle %parse-param. Enable %parse-param test in C++.
10728 2003-05-12 Paul Eggert <eggert@twinsun.com>
10730 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10731 English a bit. Fix fclose typo. Change "const char" to "char
10732 const", and use ANSI C rather than K&R for "main". Suggest
10733 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10734 and suggest yy_switch_to_buffer.
10736 2003-05-05 Paul Eggert <eggert@twinsun.com>
10738 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10739 C89. This avoids a diagnostic on compilers that define __STDC__
10740 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10741 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10743 2003-05-03 Paul Eggert <eggert@twinsun.com>
10745 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10746 Do not overrun array bounds.
10747 This should fix a bug reported today by Olatunji Oluwabukunmi in
10748 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10750 2003-04-29 Akim Demaille <akim@epita.fr>
10752 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10753 * src/getargs.c, src/getargs.h: here, as bool, not int.
10754 (nondeterministic_parser): New.
10755 * src/parse-gram.y, src/scan-gram.l: Support
10756 %nondeterministic-parser.
10757 * src/output.c (prepare): Use nondeterministic_parser instead
10758 of glr_parser where appropriate.
10759 * src/tables.c (conflict_row, action_row, save_row)
10760 (token_actions, token_actions, pack_vector): Ditto.
10762 2003-04-29 Akim Demaille <akim@epita.fr>
10764 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10766 2003-04-29 Akim Demaille <akim@epita.fr>
10768 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10769 with %pure-parser and %locations to exercise the patch from Yakov
10772 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10774 * data/yacc.c: (b4_lex_param): Corrected for the case where
10775 %lex-param is provided and %pure-parser isn't.
10777 2003-04-27 Paul Eggert <eggert@twinsun.com>
10779 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10780 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10781 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10782 if it is not defined.
10783 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10785 2003-04-26 Paul Eggert <eggert@twinsun.com>
10787 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10788 Declare to be of type suitable for the ninf value itself, not of
10789 type suitable for the corresponding table, since the latter might
10790 be unsigned but the ninf value might be negative. This fixes a
10791 bug reported by Alexandre Duret-Lutz in
10792 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10794 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10795 invokes it. We shouldn't invoke it twice because it will attempt
10796 to put error.o in the archive twice. This fixes a glitch reported
10797 by Martin Mokrejs in
10798 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10800 2003-04-21 Paul Eggert <eggert@twinsun.com>
10802 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10805 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10807 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10808 Fix obvious typo that results in uncompilable GLR parsers
10809 when both %pure-parser and %locations are used. (trivial change)
10811 2003-04-17 Paul Eggert <eggert@twinsun.com>
10813 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10814 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10815 Do not insert the expected token via unput, as this runs afoul
10816 of a POSIX-compatibility bug in flex 2.5.31.
10817 All uses changed to BEGIN the parent state,
10818 since we no longer insert the expected token via unput.
10819 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10820 that is no longer emitted after the above change.
10822 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10823 the first one. This change is from Paul Hilfinger, and it fixes
10824 regression reported by Werner Lemberg in
10825 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10827 (resolve_sr_conflict): Don't invoke state_errs_set
10828 unless one or more tokens have been explicitly made errors.
10829 Otherwise, the above change causes Bison to abort.
10831 * tests/existing.at (GNU pic Grammar): New test case, taken from
10834 2003-03-31 Akim Demaille <akim@epita.fr>
10836 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10838 2003-03-31 Akim Demaille <akim@epita.fr>
10840 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10843 2003-03-31 Akim Demaille <akim@epita.fr>
10845 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10846 From Paul Hilfinger.
10848 2003-03-29 Akim Demaille <akim@epita.fr>
10850 * m4/error.m4: Do not put under dynamic conditions some code which
10851 expansion is under static control.
10853 2003-03-29 Akim Demaille <akim@epita.fr>
10855 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10857 2003-03-29 Akim Demaille <akim@epita.fr>
10859 * doc/bison.texinfo (Strings are Destroyed): New.
10861 2003-03-13 Paul Eggert <eggert@twinsun.com>
10863 * .cvsignore: Add configure.lineno.
10864 * src/.cvsignore: Add yacc.
10865 * tests/.cvsignore: Add testsuite.log.
10866 * doc/fdl.texi: Sync with latest FSF version.
10868 2003-03-12 Paul Eggert <eggert@twinsun.com>
10870 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10871 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10872 cursor, instead of leaving it undefined. This fixes a bug
10873 reported by Tim Van Holder in
10874 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10875 * tests/input.at (Torturing the Scanner): Test the scanner on
10876 an empty input file, which was Tim Van Holder's test case.
10878 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10879 <sys/resource.h> can be included, include sys/time.h and
10880 sys/times.h first, if available. This works around the SunOS
10881 4.1.4 porting bug reported by Bruce Becker in
10882 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10884 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10885 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10886 AC_HEADER_SYS_WAIT.
10888 Merge changes from gnulib. This was prompted because the CVS
10889 snapshot didn't build on Solaris 7 due to strnlen problems.
10891 These changes need to be merged back into gnulib:
10892 * lib/hash.c: Include <stdbool.h> unconditionally.
10893 * m4/onceonly.m4 (m4_quote): New macro.
10894 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10895 Quote AC_FOREACH variable-expansions properly.
10896 The 2003-01-03 obstack.h change also needs merging.
10897 {end of changes requiring merging}
10899 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10900 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10901 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10902 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10903 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10904 New files, imported from gnulib.
10905 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10908 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10909 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10912 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10914 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10915 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
10916 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
10917 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
10918 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10919 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10920 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10921 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10922 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10923 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10924 (jm_PREREQ_ARGMATCH): Remove.
10925 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10926 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10928 * src/system.h: Include <stdbool.h> unconditionally.
10930 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10931 assuming at least C89 in the bitset code for some time now.
10933 2003-03-03 Akim Demaille <akim@epita.fr>
10937 2003-03-02 Akim Demaille <akim@epita.fr>
10939 * doc/bison.texinfo (Table of Symbols): Reactivate the
10940 documentation for %lex-param, and %parse-param.
10942 2003-03-02 Akim Demaille <akim@epita.fr>
10944 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10945 generate verbose error messages.
10946 Use the number of tokens as an upper bound in yytname, as it
10947 cannot be a non terminal.
10949 2003-03-02 Akim Demaille <akim@epita.fr>
10951 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10954 2003-03-02 Akim Demaille <akim@epita.fr>
10956 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10957 Use them to exercise yycheck overrun.
10958 Based on Andrew Suffield's grammar.
10960 2003-03-02 Akim Demaille <akim@epita.fr>
10962 Create tests/local.at for Bison generic testing macros.
10964 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10965 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10967 * tests/calc.at (AT_CHECK_CALC): Adjust.
10968 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10969 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10970 * tests/local.at: here.
10971 (AT_COMPILE_CXX): Tags the tests using it as c++.
10972 Ignore the test if CXX is not functional.
10974 2003-03-01 Paul Eggert <eggert@twinsun.com>
10976 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10977 not loc->end, since loc->end might contain garbage and this leads
10978 to undefined behavior on some platforms.
10979 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10980 depend on *loc, so that the reader doesn't give the the false
10981 impression that *loc is initialized.
10982 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10983 does not survive the return.
10985 2003-03-01 Akim Demaille <akim@epita.fr>
10987 * src/scan-gram.l (code_start): Always initialize it when entering
10988 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10989 yylex invocation. An alternative would be making it static, but
10990 then it starts with the second %%'s beginning, instead of its end.
10992 2003-02-28 Paul Eggert <eggert@twinsun.com>
10994 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10995 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10996 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10998 2003-02-26 Paul Eggert <eggert@twinsun.com>
11000 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
11001 Remove Sequent/Pyramid discussion (nobody uses them any more).
11002 Merge VMS and MS-DOS discussion; these ports may well be dead
11003 but let's keep mentioning them for now. Put <> around email
11004 addresses. Add copyright notice.
11006 2003-02-24 Paul Eggert <eggert@twinsun.com>
11008 * data/glr.c (yy_reduce_print): yylineno -> yylno,
11009 to avoid collision with flex use of yylineno.
11010 Problem reported by Bruce Lilly in
11011 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
11012 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
11013 * data/yacc.c (yy_reduce_print): Likewise.
11015 * config/depcomp: Sync with Automake 1.7.3.
11017 2003-02-21 Akim Demaille <akim@epita.fr>
11019 * data/lalr1.cc: Use temporary variables instead of casts to
11020 change integer types.
11021 Suggested by Paul Eggert.
11023 2003-02-21 Akim Demaille <akim@epita.fr>
11025 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11026 to avoid confusions with lalr1.cc's notion of Position.
11027 Suggested by Paul Eggert.
11029 2003-02-20 Akim Demaille <akim@epita.fr>
11031 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11032 before initial_columns.
11033 (location.hh): Use consistent variable names when defining the
11035 Use "last" so that we subtract from Positions, not from unsigned.
11037 2003-02-20 Akim Demaille <akim@epita.fr>
11039 * data/lalr1.cc (position.hh): New subfile, including the extended
11040 and Doxygen'ed documentation of class Position.
11041 (location.hh): Use it.

11047 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
11049 Redefine AT_YYERROR_SEES_LOC_IF using it.
11050 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
11052 Don't use the location in yy::Parser::error_ and
11053 yy::Parser::print_ when not %locations.
11054 Activate more lalr1.cc tests.
11056 2003-02-19 Akim Demaille <akim@epita.fr>
11058 * data/lalr1.cc: When displaying a line number, be sure to make it
11061 2003-02-19 Akim Demaille <akim@epita.fr>
11063 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):

11068 2003-02-19 Akim Demaille <akim@epita.fr>
11070 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11071 error recovery, mixing with/without pops and discarding of the
11074 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
11076 2003-02-17 Paul Eggert <eggert@twinsun.com>
11078 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
11079 * tests/testsuite.at (AT_COMPILE): Use them.
11080 This fixes the testsuite problem reported by Robert Lentz in
11081 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
11083 2003-02-12 Paul Eggert <eggert@twinsun.com>
11085 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
11086 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
11087 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
11088 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
11089 Check for malloc failure, for consistency with yacc.c.
11090 (yytname_size): Remove, for consistency with yacc.c.
11092 The bug still remains in data/lalr1.cc, as I didn't have time
11095 2003-02-06 Akim Demaille <akim@epita.fr>
11097 * configure.ac (GXX): Rename as...
11098 (CXX): this, to keep the original Autoconf semantics.
11100 * data/lalr1.cc: Fix b4_copyright invocations.
11101 If YYDEBUG is not defined, don't depend upon name_ being defined.
11102 (location.hh): Include string and iostream.
11103 (Position::filename): New member.
11104 (Position::Position ()): New.
11105 (operator<< (Position)): New.
11106 (operator- (Position, int)): New.
11107 (Location::first, Location::last): Rename as...
11108 (Location::begin, Location::end): these, to mock the conventional
11110 (operator<< (Location)): New.
11111 * tests/atlocal.in (CXX): New.
11112 * tests/testsuite.at (AT_COMPILE_CXX): New.
11113 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
11114 locations in a more synthetic way.
11115 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
11117 Adjust the C locations to match those from Emacs: first column is
11119 Change all the expected results.
11120 Conform to the GCS: simplify the locations when applicable.
11121 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
11122 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
11123 these CPP macros with the m4 macros new defined by...
11124 (AT_CHECK_PUSHDEFS): this, i.e.:
11125 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
11126 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
11128 (AT_CHECK_POPDEFS): Undefine them.
11129 (AT_CHECK_CALC_LALR1_CC): New.
11130 Use it for the first lalr1.cc test.
11132 2003-02-04 Akim Demaille <akim@epita.fr>
11134 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
11135 Location as is defined.
11137 2003-02-04 Akim Demaille <akim@epita.fr>
11139 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
11140 name_ being defined.
11142 2003-02-03 Paul Eggert <eggert@twinsun.com>
11144 * src/gram.h (start_symbol): Remove unused decl.
11146 Use more-consistent naming conventions for local vars.
11148 * src/derives.c (derives_compute): Change type of local var from
11149 int to rule_number.
11150 * src/gram.c (grammar_rules_partial_print): Likewise.
11151 * src/print.c (print_core): Likewise.
11152 * src/reduce.c (reduce_grammar_tables): Likewise.
11154 * src/gram.c (grammar_dump): Change name of item_number *
11155 local var from r to rp.
11156 * src/nullable.c (nullable_compute): Likewise.
11158 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
11160 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
11161 for symbol or symbol_number var.
11162 * src/reader.c (grammar_start_symbol_set): Likewise.
11163 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
11165 * src/state.c (transitions_to): Likewise.
11166 * src/state.h: Likewise.
11167 * src/tables.c (symbol_number_to_vector_number): Likewise.
11169 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
11172 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
11175 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
11178 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
11179 Use str, not s, for char * var. Use ch, not c, for character var.
11180 Use size for size var.
11182 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
11184 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
11186 * src/uniqstr.h: Likewise.
11188 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11189 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11190 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
11191 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
11192 param to have same name as that of enum, so that we don't use
11193 "s" to stand for a non-state.
11195 2003-02-02 Akim Demaille <akim@epita.fr>
11197 * src/scan-skel.l: Scan more than one inert character per yylex
11200 2003-02-01 Paul Eggert <eggert@twinsun.com>
11204 * po/LINGUAS: Add ms.
11206 2003-01-30 Akim Demaille <akim@epita.fr>
11208 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11210 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11212 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11215 Changes in response to error report by S. Eken: GLR mode does not
11216 handle negative $ indices or $ indices in embedded rules correctly.
11217 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
11219 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
11220 (b4_rhs_location): Ditto.
11221 (yyfill): New function to copy from stack tree into array
11223 (yyuserAction): Modify to allow incremental move of semantic values
11224 to rhs array when in GLR mode.
11225 Define YYFILL to use in user-defined actions to fill semantic array
11227 Remove dummy use of yystack, as there is now a guaranteed use.
11228 (yydoAction): Modify to allow incremental move of semantic values
11229 to rhs array when in GLR mode.
11230 (yyresolveAction): Ditto.
11231 (yyglrShiftDefer): Update comment.
11232 (yyresolveStates): Use X == NULL for pointers, not !X.
11233 (yyglrReduce): Ditto.
11234 (yydoAction): Ditto
11236 * tests/glr-regr1.at: Rename to ...
11237 * tests/glr-regression.at: Add new regression test for the problems
11238 described above (adapted from S. Eken).
11239 Update copyright notice.
11240 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
11241 * tests/Makefile.am: Ditto.
11243 2003-01-28 Paul Eggert <eggert@twinsun.com>
11245 * data/lalr1.cc: Do not use @output_header_name@ unless
11246 b4_defines_flag is set. This fixes two bugs reported by
11248 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11249 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11251 2003-01-21 Paul Eggert <eggert@twinsun.com>
11253 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11254 we don't need to worry about yyerrlab1 being reported as an
11255 "unused label" by non-GCC C compilers. The downside is that if
11256 locations are used then a couple of statements are duplicated each
11257 time YYERROR is invoked, but the upside is that the warnings
11259 (yyerrlab1): Move code to YERROR.
11260 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11261 This reverts some of the 2002-12-27 change.
11263 2003-01-17 Paul Eggert <eggert@twinsun.com>
11265 * src/output.c (symbol_printers_output): Fix typo that led
11266 to core dump. Problem reported by Antonio Rus in
11267 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11269 2003-01-13 Akim Demaille <akim@epita.fr>,
11270 Quoc Peyrot <chojin@lrde.epita.fr>,
11271 Robert Anisko <anisko_r@lrde.epita.fr>
11273 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11274 when the stacks contain one element, as the loop would otherwise
11275 free the last state, and then use the top state (the one we just
11276 popped). This means that the initial elements will not be freed
11277 explicitly, as is the case in yacc.c; it is not a problem, as
11278 these elements have fake values.
11280 2003-01-11 Paul Eggert <eggert@twinsun.com>
11282 * NEWS: %expect-violations are now just warnings, reverting
11283 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11284 bootstrapping problem reported by Matthias Klose; see
11285 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11286 * src/conflicts.c (conflicts_print): Likewise.
11287 * tests/conflicts.at (%expect not enough, %expect too much,
11288 %expect with reduce conflicts): Likewise.
11289 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11290 that the warning is enabled if the number of conflicts changes
11291 (not necessarily increases).
11293 * src/getargs.c (version): Update copyright year.
11295 2003-01-09 Akim Demaille <akim@epita.fr>
11297 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11299 2003-01-08 Paul Eggert <eggert@twinsun.com>
11301 * Makefile.maint (WGETFLAGS):
11302 New macro, containing "-C off" to disable proxy caches.
11303 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11304 (rel-check): Use $(WGET) instead of wget.
11306 2003-01-06 Paul Eggert <eggert@twinsun.com>
11308 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11309 the GLR paper of Scott, Johnstone and Hussain.
11311 2003-01-04 Paul Eggert <eggert@twinsun.com>
11313 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11314 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11315 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11316 (EXTRA_LIBRARIES): New var, for liby.a.
11317 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11318 (EXTRA_SCRIPTS): New var, for yacc.
11320 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11321 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11322 Problem reported by Nelson H. F. Beebe.
11324 2003-01-03 Paul Eggert <eggert@twinsun.com>
11326 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11327 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11328 when compiling Bison 1.875's `bitset bset = obstack_alloc
11329 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11331 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11332 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11333 grow to a huge size with typical invocation.
11335 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
11336 Use the pattern recommended by Autoconf 2.57, except also protect
11337 against double-definition.
11338 * src/system.h: Likewise.
11339 Portability issues reported by Nelson H. F. Beebe.
11341 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
11342 All uses changed. Provide a definition in both C and C++.
11343 (yytrue, yyfalse): Define even if defined (__cplusplus).
11345 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
11346 Reported by Nelson H. F. Beebe.
11348 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
11350 2003-01-02 Paul Eggert <eggert@twinsun.com>
11352 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
11353 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
11354 Bug reported by Nelson H. F. Beebe.
11356 2003-01-01 Paul Eggert <eggert@twinsun.com>
11360 2002-12-30 Paul Eggert <eggert@twinsun.com>
11362 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
11364 (<INITIAL>","): Here. This causes stray "," to be treated
11367 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11368 last brace in braced code when not in Yacc mode, for compatibility
11369 with Bison 1.35. This resurrects the 2001-12-15 patch to
11372 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11373 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11375 2002-12-28 Paul Eggert <eggert@twinsun.com>
11377 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11378 that of SYM's type. This fixes Debian bug 168069, reported by
11381 2002-12-28 Paul Eggert <eggert@twinsun.com>
11385 Switch back to the Yacc style of conflict reports, undoing some
11386 of the 2002-07-30 change.
11387 * doc/bison.texinfo (Understanding): Use Yacc style for
11388 conflict reports. Also, use new way of locating rules.
11389 * src/conflicts.c (conflict_report):
11390 Renamed from conflict_report_yacc, removing the old
11391 'conflict_report'. Translate the entire conflict report at once,
11392 so that we don't assume that "," has the same interpretation in
11394 (conflicts_output): Use Yacc-style conflict report for each state,
11395 instead of our more-complicated style.
11396 (conflicts_print): Use Yacc-style conflict report, except print
11397 the input file name when not emulating Yacc.
11398 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11399 Conflicted Reduction, %expect not enough, %expect too much,
11400 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11401 * tests/existing.at (GNU Cim Grammar): Likewise.
11402 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11404 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11405 fatal): Don't invoke fflush; it's not needed and it might even be
11406 harmful for stdout, as stdout might not be open.
11407 * src/reduce.c (reduce_print): Likewise.
11409 2002-12-27 Paul Eggert <eggert@twinsun.com>
11411 Fix a bug where error locations were not being recorded correctly.
11412 This problem was originally reported by Paul Hilfinger in
11413 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11415 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11416 top of the location stack's error locations.
11417 (yyerrlab): Set it. When discarding a token, push its location
11418 onto yylerrsp so that we don't lose track of the error's end.
11419 (yyerrlab1): Now is only the target of YYERROR, so that we can
11420 properly record the location of the action that failed. For GCC
11421 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11422 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11423 (yyerrlab2): New label, which yyerrlab now falls through to.
11424 Compute the error's location by applying YYLLOC_DEFAULT to
11425 the locations of all the symbols that went into the error.
11426 * doc/bison.texinfo (Location Default Action): Mention that
11427 YYLLOC_DEFAULT is also invoked for syntax errors.
11428 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11429 Error locations include the locations of all the tokens that were
11430 discarded, not just the last token.
11432 2002-12-26 Paul Eggert <eggert@twinsun.com>
11434 * src/files.c: Include quote.h.
11435 (compute_output_file_names): Warn if we detect conflicting
11436 outputs to the same file. This should catch the misunderstanding
11437 exemplified by Debian Bug 165349, reported by Bruce Stephens..
11439 * src/conflicts.c (conflicts_print): If the user specifies
11440 "%expect N", report an error if there are any reduce/reduce
11441 conflicts. This is what the manual says should happen.
11442 This fixes Debian bug 130890, reported by Anthony DeRobertis.
11443 * tests/conflicts.at (%expect with reduce conflicts): New test.
11445 Don't use m4_include on relative file names, as it doesn't work as
11446 desired if there happens to be a file with that name under ".".
11448 * m4sugar/version.m4: Remove; it was included but it wasn't used.
11449 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
11450 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
11451 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
11452 * src/output.c (output_skeleton): Use full path names when
11453 specifying a file to include; don't rely on include path, as
11454 it's unreliable when the working file contains a file with
11457 2002-12-25 Paul Eggert <eggert@twinsun.com>
11459 Remove obsolete references to bison.simple and bison.hairy.
11460 Problem mentioned by Aubin Mahe in
11461 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
11462 * data/glr.c: Comment fix.
11463 * doc/bison.1: Remove references. Also, mention "yacc".
11465 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
11468 * src/parse-gram.y (declaration): Use enum "report_states" rather
11469 than its numeric value 1.
11471 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
11472 opening a new one. This fixes Debian bug 165349, reported by
11475 2002-12-24 Paul Eggert <eggert@twinsun.com>
11479 * Makefile.maint (cvs-update): Don't assume that the shell
11480 supports $(...), as Solaris sh doesn't.
11482 * src/parse-gram.y (lloc_default): Remove test for empty
11483 nonterminals at the end, since it didn't change the result.
11485 2002-12-24 Paul Eggert <eggert@twinsun.com>
11487 If the user does not define YYSTYPE as a macro, Bison now declares it
11488 using typedef instead of defining it as a macro. POSIX requires this.
11489 For consistency, YYLTYPE is also declared instead of defined.
11491 %union directives can now have a tag before the `{', e.g., the
11492 directive `%union foo {...}' now generates the C code
11493 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11494 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11495 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11496 instead of `yyltype'.
11498 `yystype' and `yyltype' are now obsolescent macros instead of being
11499 typedefs or tags; they are no longer documented and will be
11500 withdrawn in a future release.
11502 * data/glr.c (b4_location_type): Remove.
11503 (YYSTYPE): Renamed from yystype.
11504 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
11505 (struct YYLTYPE): Renamed from struct yyltype.
11506 (YYLTYPE): Renamed from yyltype.
11507 (yyltype, yystype): New (and obsolescent) macros,
11508 for backward compatibility.
11509 * data/yacc.c: Likewise.
11511 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11512 does not specify a union tag. This is for compatibility with
11515 * src/parse-gram.y (add_param): 2nd arg is now char * not char
11516 const *, since it is now modified by stripping surrounding { }.
11517 (current_braced_code): Remove.
11518 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
11519 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
11520 trailing " {...}". Now of type <chars>.
11521 (grammar_declaration): Adjust to bundled tokens.

11524 (token_name): New function.
11526 * src/reader.h (braced_code, current_braced_code): Remove.
11527 (token_name): New decl.
11529 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
11530 token_type, not braced_code code_kind. All uses changed.
11531 (SC_PRE_CODE): New state, for scanning after a keyword that
11532 has (or usually has) an immediately-following braced code.
11533 (token_type): New local var, to keep track of which token type
11534 to return when scanning braced code.
11535 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
11536 <INITIAL>"%parse-param", <INITIAL>"%printer",
11537 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
11538 instead of returning a token type immediately.
11539 (<INITIAL>"{"): Set token type.
11540 (<SC_BRACED_CODE>"}"): Use it.
11541 (handle_action_dollar, handle_action_at): Now returns bool
11542 indicating success. Fail if ! current_rule; this prevents a core dump.
11543 (handle_symbol_code_dollar, handle_symbol_code_at):
11544 Remove; merge body into caller.
11545 (handle_dollar, handle_at): Complain in invalid contexts.
11547 * NEWS, doc/bison.texinfo: Document the above.
11548 * NEWS: Fix years and program names in copyright notice.
11550 2002-12-17 Paul Eggert <eggert@twinsun.com>
11552 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
11553 Reporting, Table of Symbols): Omit mentions of %lex-param and
11554 %parse-param from the documentation for now.
11556 2002-12-15 Paul Eggert <eggert@twinsun.com>
11558 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
11559 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
11560 lookahead symbol, and which sets yychar in parser actions) and it
11561 disagreed with the Bison documentation. Bug
11562 reported by Andrew Walrond.
11564 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
11565 as the caller now does that.
11566 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
11567 (YYEMPTY): Parenthesize right hand side, since others use it.
11568 (yyparse): Don't assume that our generated code is the only code
11571 2002-12-13 Paul Eggert <eggert@twinsun.com>

11582 * po/LINGUAS: Add da.
11584 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
11585 problem with latest <getopt.h>.
11586 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
11588 * doc/fdl.texi: Upgrade to 1.2.
11589 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
11590 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
11591 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
11593 * config/install-sh: Sync with autotools.
11595 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
11596 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11597 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
11598 locations are requested.
11599 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
11600 locations are requested.
11602 2002-12-12 Paul Eggert <eggert@twinsun.com>
11604 Remove unportable casts and storage allocation tricks.
11605 While we're at it, remove almost all casts, since they
11606 usually aren't needed and are a sign of trouble.
11608 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11610 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11611 the pointer DSET returned by malloc; this isn't portable.

11613 Similarly for DERIVES.
11614 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11615 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11616 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11618 * src/derives.c (derives_compute): Do not bother invoking

11622 rather than XMALLOC (char, N).
11624 * src/files.c (filename_split): Rewrite to avoid cast.
11626 * src/gram.h (symbol_number_as_item_number,
11627 item_number_as_symbol_number, rule_number_as_item_number,
11628 item_number_as_rule_number):
11629 Now inline functions rather than macros, to avoid casts.
11630 * src/state.h (state_number_as_int): Likewise.

11632 symbol_number_to_vector_number): Likewise.
11634 * src/gram.h (int_of_rule_number): Remove; no longer used.
11636 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,

11639 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11642 * src/muscle_tab.c (muscle_m4_output):
11643 Now inline. Return bool, not int.
11644 * src/state.c (state_compare): Likewise.
11645 * src/symtab.c (symbol_check_defined,
11646 symbol_check_alias_consistency, symbol_pack, symbol_translation,

11656 hash_symbol_hasher): Likewise.
11657 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11658 * src/muscle_tab.c (muscles_m4_output):
11659 Use new functions instead of casting old functions unportably.
11660 * src/state.c (state_hash_new): Likewise.
11661 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11662 symbols_token_translations_init):
11664 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11666 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11667 var instead of casting to long, to avoid casts.
11668 (prepare_states): Use MALLOC rather than alloca, so that we don't
11669 have to worry about alloca.
11670 * src/state.c (state_hash_lookup): Likewise.
11672 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11673 local var instead of casting to unsigned char, to avoid casts.
11675 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11676 STATE_ALLOC): Remove.
11677 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11678 rather than calloc, and use offsetof to avoid allocating slightly
11680 (state_new): Initialize all members.
11682 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11684 * src/symtab.c (symbol_free): Remove; unused.

11687 hashing-related ones.
11689 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11690 (symbol_processor): Remove.
11691 (symbols_do): Remove decl; now static.
11693 * src/system.h (alloca): Remove; decl no longer needed.
11694 (<stddef.h>): Include, for offsetof.
11695 (<inttypes.>, <stdint.h>): Include if available.
11696 (uintptr_t): New type, if system lacks it.
11697 (CALLOC, MALLOC, REALLOC): New macros.
11698 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these

11714 2002-12-09 Paul Eggert <eggert@twinsun.com>
11716 Change identifier spellings to avoid collisions with names
11717 that are reserved by POSIX.
11719 Don't use names ending in _t, since POSIX reserves them.
11720 For consistency, remove _e and _s endings -- they're weren't
11721 needed to remove ambiguity. All uses changed.
11722 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11723 turn was just renamed from struniq_t.
11724 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11725 which in turn was just renamed from struniq_processor_t.
11726 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

11797 value_t_as_yystype -> value_as_yystype.
11799 Don't include <errno.h> in the mainstream code, since it
11800 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11801 * lib/get-errno.c, lib/get-errno.h: New files.
11802 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

11818 * src/uniqstr.c: Renamed from src/struniq.c.
11819 * src/uniqstr.h: Renamed from src/struniq.h.

11857 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11860 Sort include-file uses.
11862 Reorder all include files under src to be in the order "system.h".
11863 then the ../lib include files in angle brackets (alphabetized),
11864 then the . include files in double-quotes (alphabetized). Fix
11865 dependency breakages encountered in this process, as follows:
11866 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11867 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11868 * src/state.h: Include "symtab.h".
11870 2002-12-08 Paul Eggert <eggert@twinsun.com>
11872 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11873 since this causes problems when __file__ contains character
11874 sequences like "@" that are treated specially by src/scan-skel.l.
11875 Instead, just use the file's basename. This fixes the bug
11876 reported by Martin Mokrejs in
11877 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11879 2002-12-06 Paul Eggert <eggert@twinsun.com>
11881 Add support for rules that do not have trailing semicolons, as

11885 * src/location.c: Include <quotearg.h>.
11886 (empty_location): Now const.
11887 (location_print): New function. Follow the recommendation of the
11888 GNU Coding Standards for locations that span file boundaries.
11889 * src/location.h: Do not include <quotearg.h>; no longer needed.
11890 (boundary): New type.
11891 (location_t): Use it. This allows locations to span file boundaries.
11892 All member uses changed: file -> start.file or end.file (as needed),

11894 last_line -> end.line, last_column -> end.column.
11895 (equal_boundaries): New function.
11896 (LOCATION_RESET, LOCATION_STEP): Remove.
11897 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11898 (empty_location): Now const.
11899 (location_print): New decl.
11900 * src/parse-gram.y (lloc_default): New function, which handles
11901 empty locations more accurately.
11902 (YYLLOC_DEFAULT): Use it.
11903 (%token COLON): Remove.
11904 (%token ID_COLON): New token.

11919 the work. All uses removed.
11920 (scanner_cursor): New var.
11921 (adjust_location): Renamed from extend_location. It now sets
11922 *loc and adjusts the scanner cursor. All uses changed.
11923 Don't bother testing for CR.
11924 (handle_syncline): Remove location arg; now updates scanner cursor.
11925 All callers changed.
11926 (unexpected_end_of_file): Now accepts start boundary of token or
11927 comment, not location. All callers changed. Update scanner cursor,
11929 (SC_AFTER_IDENTIFIER): New state.
11930 (context_state): Renamed from c_context. All uses changed.
11931 (id_loc, code_start, token_start): New local vars.
11932 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11933 processing of Yacc white space and equivalents here.
11934 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11935 instead of returning ID immediately, since we need to search for
11936 a subsequent colon.
11937 (<INITIAL>"'", "\""): Save token_start.
11938 (<INITIAL>"%{", "{", "%%"): Save code_start.
11939 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11940 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11941 BEGIN context_state at end, not INITIAL.
11942 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11943 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11944 Return correct token start.
11945 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11946 the start of a character, string or multiline comment is found.
11947 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11948 Reduction): Adjust reported locations to match the more-precise
11949 results now expected.
11950 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11951 * tests/reduce.at (Useless Rules, Reduced Automaton,
11952 Underivable Rules): Likewise.
11953 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11954 or "|"' now that so many other tokens are allowed by the new grammar.
11956 * src/complain.h (current_file): Remove duplicate decl;
11957 current_file is now owned by files.h.
11958 * src/complain.c, src/scan-gram.l: Include files.h.
11960 2002-12-06 Paul Eggert <eggert@twinsun.com>
11962 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11963 promotes to int; it might be unsigned int.
11964 * data/yacc.c (yy_reduce_print): Likewise.
11966 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11967 be #defined in the prologue, not in the Bison declarations.
11968 This fixes Debian Bug 102878, reported by Shaul Karl.
11970 2002-12-02 Paul Eggert <eggert@twinsun.com>
11972 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11973 * lib/strtoul.c: New file, from gnulib.
11974 This fixes a porting bug reported by Peter Klein in
11975 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11977 2002-11-30 Paul Eggert <eggert@twinsun.com>
11979 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11980 and put only a forward declaration in the prologue. This is for
11981 consistency with the other scanner helper functions.
11983 Type clashes now generate warnings, not errors, since it
11984 appears that POSIX may allow some grammars with type clashes.
11985 * src/reader.c (grammar_current_rule_check): Warn about
11986 type clashes instead of complaining.
11987 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11989 Add Yacc library, since POSIX requires it.
11990 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11991 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11992 * lib/main.c, lib/yyerror.c: New files.
11994 gram_error can be static; it need not be extern.
11995 * src/reader.h (gram_error): Remove decl.
11996 * src/parse-gram.y (gram_error): Now static. Add static decl.
11997 (print_token_value): Omit parameter names from forward decl,
12000 2002-11-29 Paul Eggert <eggert@twinsun.com>
12002 * doc/bison.texinfo: Emphasize that yylex and yyerror must
12003 be declared before being used. E.g., one should typically
12004 declare them in the prologue. Use GNU coding style in examples.
12005 Put "const" consistently after the type it modifies. Mention
12006 that C99 supports "inline". Mention that yyerror traditionally
12009 %parse-param and %lex-param now take just one argument, the
12010 declaration; the argument name is deduced from the declaration.
12012 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12013 Reporting, Table of Symbols): Document this.
12014 * src/parse-gram.y (add_param): New function.
12016 (declaration): Implement new rule for %parse-param and %lex-param.
12017 * src/scan-gram.l: "," now elicits a warning, rather than being
12018 a token; this is more compatible with byacc.
12019 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12021 2002-11-27 Paul Eggert <eggert@twinsun.com>
12023 Rename identifiers to avoid real and potential collisions.
12025 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12026 to avoid collision with lex macro described by Bruce Lilly in
12027 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12028 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12029 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12030 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12032 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12033 The name "yycontrol" violates the name space rules, and this stuff
12034 wasn't being used anyway.
12035 (input): Remove action; this stuff wasn't being used.
12036 (gram_error): Rename local variable yylloc -> loc.
12037 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12038 (YY_DECL): Don't use "yy" at start of local variables.
12039 All uses changed, e.g., yylloc -> loc.
12040 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12041 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12042 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12043 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12045 * src/parse-gram.y (gram_error): loc is now const *.
12046 * src/reader.h (gram_error): Likewise.
12048 2002-11-24 Paul Eggert <eggert@twinsun.com>
12052 * tests/actions.at (Actions after errors): Use an output format
12053 more similar to that of the Printers and Destructors test.
12054 Test the position of the ';' token too.
12055 (Printers and Destructors): Likewise.
12056 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12057 unnecessarily alarming people when the test fails.
12059 * data/yacc.c (yyerrlab1): Move this label down, so that the
12060 parser does not discard the lookahead token if the user code
12061 invokes YYERROR. This change is required for POSIX conformance.
12063 * lib/error.c: Sync with gnulib.
12065 2002-11-22 Paul Eggert <eggert@twinsun.com>
12067 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12068 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12069 * lib/xmalloc.c: Likewise.
12071 2002-11-20 Paul Eggert <eggert@twinsun.com>
12073 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12075 2002-11-20 Paul Eggert <eggert@twinsun.com>
12077 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12078 should use `if (! x) abort ();' rather than `assert (x);', and
12079 anyway it's one less thing to worry about configuring.
12081 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
12082 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
12083 and replace all instances of assert with abort.
12084 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
12085 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
12087 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
12088 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
12089 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
12090 hash_find_entry, hash_rehash, hash_insert): Likewise.
12091 * src/conflicts.c (resolve_sr_conflict): Likewise.
12092 * src/lalr.c (set_goto_map, map_goto): Likewise.
12093 * src/nullable.c (nullable_compute): Likewise.
12094 * src/output.c (prepare_rules, token_definitions_output): Likewise.
12095 * src/reader.c (packgram, reader): Likewise.
12096 * src/state.c (state_new, state_free, state_transitions_set,
12097 state_reduction_find): Likewise.
12098 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
12099 symbol_pack): Likewise.
12100 * src/tables.c (conflict_row, pack_vector): Likewise.
12101 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12102 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12103 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
12104 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
12106 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
12107 (ARGMATCH_CONSTRAINT): New macro.
12108 (ARGMATCH_ASSERT): Use it.
12110 * src/system.h (verify): New macro.
12111 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
12112 rather than assert.
12113 * src/tables.c (tables_generate): Likewise.
12115 * src/struniq.c (struniq_assert): Now returns void, and aborts
12116 if the assertion is false.
12117 (struniq_assert_p): Remove.
12118 * src/struniq.h: Likewise.
12120 2002-11-18 Paul Eggert <eggert@twinsun.com>
12122 * data/glr.c (yygetLRActions): Replace `yyindex' with
12123 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
12124 This fixes the regression with Sun ONE Studio 7 cc that I reported in
12125 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
12127 2002-11-18 Akim Demaille <akim@epita.fr>
12129 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
12131 From Tim Van Holder.
12133 2002-11-17 Paul Eggert <eggert@twinsun.com>
12135 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
12136 to "SyntaxError" for consistency with my 2002-11-15 change.
12138 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
12139 not define to {}, since this breaks the common use of `YYDPRINTF
12140 ((...));' if a single statement is desired (e.g. before `else').
12141 Work around GCC warnings by surrounding corresponding calls with
12143 (yyhasResolvedValue): Remove unused function.
12144 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
12146 (yyreportSyntaxError): Renamed from yyreportParseError.
12147 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
12149 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
12150 extern when possible. Remove unused initializations.
12152 2002-11-16 Akim Demaille <akim@epita.fr>
12154 Augment the similarity between GLR and LALR traces.
12156 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
12157 (YY_REDUCE_PRINT): New.
12158 (yyparse): Use them.
12159 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
12161 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
12162 state reached after the reduction/recovery, since...
12163 (yyparse, yyprocessOneStack): Report the state we are entering in.
12165 2002-11-16 Akim Demaille <akim@epita.fr>
12167 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
12168 Add support for --trace=skeleton.
12169 * src/scan-skel.l: %option debug.
12170 Scan strings of non-@ or \n instead of character by character.
12171 (scan_skel): Handle trace_skeleton.
12173 (@output_parser_name@, @output_header_name@): ``Restore'' their
12174 support (used to be M4 macros).
12175 * data/yacc.c: Quote larger chunks, a la glr.c.
12176 * data/lalr1.cc: Likewise.
12177 The header guards are no longer available, so use some other
12178 string than `YYLSP_NEEDED'.
12180 2002-11-16 Akim Demaille <akim@epita.fr>
12182 Make the ``Printers and Destructors'' test more verbose, taking
12183 `yacc.c''s behavior as (possibly wrong) reference.
12185 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
12186 instead of fprint on stdout.
12187 Set and report the last_line of the symbols.
12188 Consistently display values and locations.
12190 2002-11-16 Paul Eggert <eggert@twinsun.com>
12192 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12194 2002-11-15 Paul Eggert <eggert@twinsun.com>
12196 * tests/actions.at (Actions after errors): New test case.
12198 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12199 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12200 tests/action.at, tests/calc.at, tests/conflicts.at,
12201 tests/cxx-type.at, tests/regression.at:
12202 "parse error" -> "syntax error" for POSIX compatibility.
12203 "parsing stack overflow..." -> "parser stack overflow" so
12204 that code matches Bison documentation.
12206 2002-11-15 Akim Demaille <akim@epita.fr>
12208 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12209 take two BRACED_CODE, not two string_content.
12210 Free the scanner's obstack when we are done.
12211 (code_content): New.
12212 * tests/calc.at: Adjust.
12213 * doc/bison.texinfo: Adjust.
12214 Also, make sure to include the `,' for these declarations.
12216 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12218 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12219 definition; avoids potential autoreconf problems.
12221 2002-11-15 Akim Demaille <akim@epita.fr>
12223 Always check the value returned by yyparse.
12225 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12226 returned by yyparse.
12227 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
12229 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
12230 returned by yyparse.
12232 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12234 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12237 2002-11-14 Paul Eggert <eggert@twinsun.com>
12239 * src/output.c (output_skeleton): Call xfopen instead of
12240 duplicating xfopen's body.
12242 Fix bugs reported by Nelson H. F. Beebe in
12243 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12245 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12246 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12247 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12248 file twice in the grammar, as an extra check.
12250 * tests/input.at (Torturing the Scanner): Surround the
12251 backslash-newline tests with "#if 0", to make it less likely that
12252 we'll run into compiler bugs. Bring back solitary \ inside
12253 comment, but add a closing comment to work around HP C bug. Don't
12254 test backslash-newline in C character constant.
12256 2002-11-14 Akim Demaille <akim@epita.fr>
12258 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12259 status of the compiler.
12260 Calling `exit 1' is no longer needed.
12261 Reported by Nelson H. F. Beebe.
12263 2002-11-14 Akim Demaille <akim@epita.fr>
12265 * tests/atlocal.in (CPPFLAGS): We have config.h.
12266 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12268 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12269 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12270 * tests/regression.at, tests/torture.at: Use them for all the
12271 grammars that are to be compiled.
12272 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12273 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12274 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12276 2002-11-14 Akim Demaille <akim@epita.fr>
12278 * doc/bison.texinfo: Various formatting changes (alignments in
12279 samples, additional @group/@end group, GCS in samples.
12280 Use @deffn instead of simple @table to define the directives,
12281 macros, variables etc.
12283 2002-11-13 Paul Eggert <eggert@twinsun.com>
12285 Fix some bugs reported by Albert Chin-A-Young in
12286 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12288 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12289 -o c"; the HP C compiler chatters during compilation.
12290 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12291 * tests/headers.at (export YYLTYPE): Likewise.
12293 * tests/input.at (Torturing the Scanner): Remove lines containing
12294 solitary backslashes, as they tickle a bug in the HP C compiler.
12296 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12297 comments, since they're not portable. Use GNU coding style.
12299 2002-11-13 Akim Demaille <akim@epita.fr>
12301 * data/yacc.c: Leave bigger chunks of quoted text.
12302 (YYDSYMPRINTF): New.
12303 Use it to report symbol activities.
12304 * data/glr.c (YYDSYMPRINTF): New.
12307 2002-11-12 Paul Eggert <eggert@twinsun.com>
12311 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12312 (yyglrReduce): Return yyok, not 0.
12313 This should avoid the enumerated-type warnings reported
12314 by Nelson H. F. Beebe in
12315 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12317 * lib/bbitset.h (BITSET_INLINE): Remove.
12318 * lib/bitset.h [! BITSET_INLINE]: Remove.
12319 (bitset_set, bitset_reset, bitset_test): Rename local vars
12320 to avoid shadowing warnings by GCC.
12322 * data/glr.c (inline): Remove #define. It's the user's
12323 responsibility to #define it away, just like 'const'.
12324 This fixes one of the bugs reported by Nelson H. F. Beebe in
12325 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12327 * Makefile.maint (po-check): Scan .l and .y files instead of the
12328 .c and the .h files that they generate. This fixes the bug
12329 reported by Tim Van Holder in:
12330 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12331 Look for N_ as well as for _. Try to avoid matching #define for
12333 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12334 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
12335 * src/scan-gram.l: Revamp regular expressions so that " and '
12336 do not confuse xgettext.
12338 * src/struniq.h (struniq_new): Do not declare the return type
12339 to be 'const'; this violates the C standard.
12340 * src/struniq.c (struniq_new): Likewise.
12342 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
12344 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
12345 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
12348 2002-11-12 Akim Demaille <akim@epita.fr>
12350 * Makefile.maint: Sync with Autoconf:
12351 (local_updates): New.
12353 2002-11-12 Akim Demaille <akim@epita.fr>
12355 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
12357 2002-11-12 Akim Demaille <akim@epita.fr>
12359 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
12362 2002-11-12 Akim Demaille <akim@epita.fr>
12364 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
12367 2002-11-12 Akim Demaille <akim@epita.fr>
12369 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
12370 Use it to test the GLR parser.
12372 2002-11-12 Akim Demaille <akim@epita.fr>
12374 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
12376 * data/glr.c (yystos): New.
12377 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
12378 (YYDSYMPRINT): New.
12379 (yyval): Don't define it, it is handled via M4.
12380 (yyrecoverParseError): Free verbosely the discarded symbols.
12381 * data/yacc.c (yysymprint): Remove, rather...
12382 (b4_yysymprint_generate): invoke.
12383 * data/c.m4 (b4_yysymprint_generate): New.
12384 Accept pointers as arguments, as opposed to the version from
12386 (b4_yydestruct_generate): Likewise.
12387 * tests/cations.at (Printers and Destructors): Use Bison directives
12388 instead of CPP macros.
12389 Don't rely on internal details.

12488 Revamp to fix many (but not all) of the C- and M4-related quoting
12489 problems. Among other things, this fixes the Bison bug reported
12490 by Jan Hubicka when processing the Bash grammar; see:
12491 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
12493 Use new @ escapes consistently. Represent brackets with @{ and @}
12494 rather than @<:@ and @:>@, since this works a bit better with dumb
12495 editors like vi. Represent @ with @@, since @ is now consistently
12496 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12497 __ofile__, to avoid unexpected expansions. Similarly, use @output
12498 rather than #output.
12500 * data/c.m4 (b4_copyright): Omit file name from comment, since
12501 the file name could contain "*/".
12502 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12503 be quoted. All uses changed.
12505 * data/glr.c: Use new @ escapes consistently.
12506 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12507 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
12508 Remove, since they couldn't handle arbitrary characters in file
12510 * data/lalr1.cc: Likewise.
12511 * data/yacc.c: Likewise.
12513 * src/files.c (output_infix): Remove; all uses removed.
12514 * src/files.h: Likewise.
12516 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
12517 mishandled funny characters in file names, and anyway it isn't
12519 * data/yacc.c: Likewise.
12520 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
12522 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
12523 * data/yacc.c: Likewise.
12525 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
12527 (muscle_init): Quote filename as a C string.
12528 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
12529 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
12530 * src/output.c (escaped_file_name_output): New function.
12531 (prepare_symbols): Quote tokens for M4.
12532 (prepare): Don't insert output_infix, output_prefix,
12533 output_parser_name, output_header_name; this is now down by scan-skel.
12534 Insert skeleton as a C string.
12536 * src/output.c (user_actions_output, symbol_destructors_output,
12537 symbol_printers_output): Quote filenames for C and M4.
12538 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12540 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12541 escapes other than \\ and \'; this simplifies the code.
12542 (<SC_STRING>): Likewise, for \\ and \".
12543 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12544 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12545 Use new escapes @{ and @} for [ and ].
12547 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12548 them with auto vars.
12549 Switch to new escape scheme, where @ is the escape character uniformly.
12550 Abort if a stray escape character is found. Avoid unbounded input
12551 buffer when parsing non-escaped text.
12553 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12554 __oline__, #output, $@, and @{ do not have unintended meanings.
12556 2002-11-09 Paul Eggert <eggert@twinsun.com>
12558 Fix the test failure due to GCC warnings described in
12559 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
12560 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
12561 evaluate to 0 if it's impossible for NINF to be in the respective
12563 (yygetLRActions, yyrecoverParseError): Use them.
12565 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12566 counted in the token inserted at end of file. Now takes
12567 location_t *, not location_t, so that the location can be
12568 adjusted. All uses changed.
12570 * tests/regression.at (Invalid inputs): Adjust wording in
12571 diagnostic to match the new behavior.
12573 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
12574 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
12575 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
12576 abort ();'. This reduces the runtime of the "Many lookaheads"
12577 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
12580 2002-11-07 Paul Eggert <eggert@twinsun.com>
12582 * src/parse-gram.y (CHARACTER): Remove unused token.
12585 * src/scan-gram.l: Remove stack option. We no longer use the
12586 stack, since the stack was never deeper than 1; instead, use the
12587 new auto var c_context to record the stacked value.
12589 Remove nounput option. At an unexpected end of file, we now unput
12590 the minimal input necessary to end cleanly; this simplifies the
12593 Avoid unbounded token sizes where this is easy.
12595 (unexpected_end_of_file): New function.
12596 Use it to systematize the error message on unexpected EOF.
12597 (last-string): Now auto, not static.

12601 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12602 not the (never otherwised-used) CHARACTER.
12604 2002-11-07 Akim Demaille <akim@epita.fr>

12661 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12662 "integer out of range" rather than "invalid value".
12663 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12666 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12667 Also, remove one static variable in the scanner.
12669 * src/scan-gram.l (braces_level): Now auto, not static.
12670 Initialize to zero if the compiler is being picky.
12671 (INITIAL): Clear braces_level instead of incrementing it.
12672 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

12832 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12833 Check for close failures.

12836 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12838 * src/output.c (output_skeleton): Use xfclose rather than fclose
12839 and ferror. xfclose now checks ferror.
12841 * data/glr.c (YYLEFTMOST_STATE): Remove.
12842 (yyreportTree): Use a stack-based leftmost state. This avoids
12843 our continuing battles with bogus warnings about initializers.

12861 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12862 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12863 Don't assume strdup exists; POSIX says its an XSI extension.
12864 Check for buffer overflow on input.
12866 2002-10-24 Akim Demaille <akim@epita.fr>
12868 * src/output.c (output_skeleton): Don't disable M4sugar comments
12869 too soon: it results in comments being expanded.
12870 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
12873 2002-10-24 Akim Demaille <akim@epita.fr>
12875 * data/yacc.c (m4_int_type): New.
12876 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12877 char' as only yacc.c wants K&R portability.
12878 * data/glr.c (yysigned_char): Remove.
12879 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12880 Reported by Quoc Peyrot.
12882 2002-10-23 Paul Eggert <eggert@twinsun.com>
12884 * src/main.c (main): With --trace=time, report times even if a
12885 non-fatal error occurs. Formerly, the times were reported in some
12886 such cases but not in others.
12887 * src/reader.c (reader): Just return if a complaint has been issued,
12888 instead of exiting, so that 'main' can report times.
12890 2002-10-22 Akim Demaille <akim@epita.fr>
12892 * src/system.h: Include sys/types.
12893 Reported by Bert Deknuydt.
12895 2002-10-23 Paul Eggert <eggert@twinsun.com>
12897 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12898 Suggested by Art Haas.
12900 2002-10-22 Paul Eggert <eggert@twinsun.com>
12902 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12903 decl; not needed any more.
12904 * src/main.c (main): Use return to exit, undoing yesterday's change.
12905 The last OS that we could find where this wouldn't work is
12906 SunOS 3.5, and that's too old to worry about now.
12908 * data/glr.c (struct yyltype): Define members even when not
12909 doing locations. This is more consistent with yacc.c, and it
12910 works around the following bug reports:
12911 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12912 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12914 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12915 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12916 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12918 2002-10-22 Akim Demaille <akim@epita.fr>
12920 * data/README: New.
12922 2002-10-21 Paul Eggert <eggert@twinsun.com>
12924 Be consistent about 'bool'; the old code used an enum in one
12925 module and an int in another, and this violates the C standard.
12926 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12927 * configure.ac (AC_HEADER_STDBOOL): Add.
12928 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12929 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12930 * src/symtab.c (hash_compare_symbol_t): Likewise.
12931 * src/system.h (bool, false, true): Use a definition consistent
12932 with ../lib/hash.c. All uses changed.
12934 * src/complain.c (warning_issued): Renamed from warn_message_count,
12935 so that we needn't worry about integer overflow (!).
12936 Now of type bool. All uses changed.
12937 (complaint_issued): Renamed from complain_message_count; likewise.
12939 * src/main.c (main): Use exit to exit with failure.
12941 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12942 rather than 1 and 0.
12943 * src/main.c (main): Likewise.
12944 * src/getargs.c (getargs): Likewise.
12945 * src/reader.c (reader): Likewise.
12947 * src/getarg.c (getargs): Remove duplicate code for
12948 "Try `bison --help'".
12950 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12951 What was that "2" for?
12953 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12954 * src/getargs.c (usage): Likewise.
12956 * src/getargs.c (getargs): When there are too few operands, report
12957 the last one. When there are too many, report the first extra
12958 one. This is how diffutils does it.
12960 2002-10-20 Paul Eggert <eggert@twinsun.com>
12962 Remove K&R vestiges.
12963 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12964 * src/complain.c (VA_START): Remove. Assume prototypes.
12965 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12966 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12967 fatal): Assume prototypes.
12968 * src/complain.h: Assume prototypes.
12969 * src/system.h (PARAMS): Remove.
12970 Include <limits.h> unconditionally, since it's guaranteeed even
12971 for a freestanding C89 compiler.
12972 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12973 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12975 2002-10-20 Akim Demaille <akim@epita.fr>
12977 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
12978 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
12979 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
12980 (yyresolveStates, yyresolveAction, yyresolveStack)
12981 (yyprocessOneStack): Use them.
12982 (yy_reduce_print): New.
12983 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12985 2002-10-20 Akim Demaille <akim@epita.fr>
12987 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12988 arguments and output `void'.
12989 (b4_c_function): Rename as...
12990 (b4_c_function_def): this.
12991 (b4_c_function_decl, b4_c_ansi_function_def)
12992 (b4_c_ansi_function_decl): New.
12993 Change the interpretation of the arguments: before `int, foo', now
12995 * data/yacc.c (yyparse): Prototype and define thanks to these.
12996 Adjust b4_c_function_def uses.
12997 * data/glr.c (yyparse): Likewise, but ANSI only.
12999 2002-10-20 Akim Demaille <akim@epita.fr>
13001 * src/output.c (prepare): Move the definition of `tokens_number',
13002 `nterms_number', `undef_token_number', `user_token_number_max'
13004 (prepare_tokens): Here.
13005 (prepare_tokens): Rename as...
13006 (prepare_symbols): this.
13007 (prepare): Move the definition of `rules_number' to...
13008 (prepare_rules): here.
13009 (prepare): Move the definition of `last', `final_state_number',
13010 `states_number' to...
13011 (prepare_states): here.
13012 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
13014 2002-10-20 Akim Demaille <akim@epita.fr>
13016 * src/tables.h, src/tables.c, src/output.c: Comment changes.
13018 2002-10-20 Akim Demaille <akim@epita.fr>
13020 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
13023 2002-10-20 Akim Demaille <akim@epita.fr>
13025 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
13026 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
13028 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
13030 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
13031 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
13034 2002-10-19 Paul Eggert <eggert@twinsun.com>
13036 Do not create a temporary file, as that involves security and
13037 cleanup headaches. Instead, use a pair of pipes.
13038 Derived from a suggestion by Florian Krohm.
13039 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13040 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
13041 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
13042 (BISON_PREREQ_SUBPIPE): Add.
13043 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
13044 Add subpipe.h, subpipe.c.
13045 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
13046 * po/POTFILES.in: Add lib/subpipe.c.
13047 * src/output.c: Include "subpipe.h".
13048 (m4_invoke): Remove decl.
13049 (scan_skel): New decl.
13050 (output_skeleton): Use pipe rather than temporary file for m4 input.
13051 Check that m4sugar.m4 is readable, to avoid deadlock.
13052 Check for pipe I/O error.
13053 * src/scan-skel.l (readpipe): Remove decl.
13054 (scan_skel): New function, to be used in place of m4_invoke.
13055 Read from stream rather than file.
13057 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13058 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13059 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13060 this generates a more-accurate value anyway.
13062 * lib/timevar.c (timervar_accumulate): Rename locals to
13063 avoid confusion with similarly-named more-global.
13064 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13066 * src/output.c (prepare): Use xstrdup to convert char const *
13067 to char *, to avoid GCC warning.
13069 2002-10-19 Akim Demaille <akim@epita.fr>
13071 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13072 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13073 Use them to have `calc.y' ready for %pure-parser.
13074 * data/yacc.c (YYLEX): Pass a yylex return type to
13075 b4_c_function_call.
13077 2002-10-19 Akim Demaille <akim@epita.fr>
13079 Prototype support of %lex-param and %parse-param.
13081 * src/parse-gram.y: Add the definition of the %lex-param and
13082 %parse-param tokens, plus their rules.
13083 Drop the `_' version of %glr-parser.
13085 * src/scan-gram.l (INITIAL): Scan them.
13086 * src/muscle_tab.c: Comment changes.
13087 (muscle_insert, muscle_find): Rename `pair' as `probe'.
13088 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
13089 (muscle_entry_s): The `value' member is no longer const.
13090 Adjust all dependencies.
13091 * src/muscle_tab.c (muscle_init): Adjust: use
13092 MUSCLE_INSERT_STRING.
13093 Initialize the obstack earlier.
13094 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
13095 (muscle_pair_list_grow): New.
13096 * data/c.m4 (b4_c_function_call, b4_c_args): New.
13097 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
13098 * tests/calc.at: Use %locations, not --locations.
13099 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
13101 2002-10-19 Akim Demaille <akim@epita.fr>
13103 * src/getargs.c (usage): Take status as argument and exit
13105 Report the traditional `Try ... --help' message when status != 0.
13106 (usage, version): Don't take a FILE * as arg, it is pointless.
13107 (getargs): When there is an incorrect number of arguments, make it
13108 an error, and report it GNUlically thanks to `usage ()'.
13110 2002-10-18 Paul Eggert <eggert@twinsun.com>
13112 * data/glr.c (yyreportParseError): Don't assume that sprintf
13113 yields the length of the printed string, as this is not true
13114 on SunOS 4.1.4. Reported by Peter Klein.
13116 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
13117 * tests/conflicts.at (%nonassoc and eof): Likewise.
13118 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
13120 2002-10-17 Akim Demaille <akim@epita.fr>
13122 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
13123 * src/getargs.c (trace_types, trace_args): Adjust.
13124 * src/reader.c (grammar_current_rule_prec_set)
13125 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
13126 Standardize error messages.
13127 And s/@prec/%prec/!
13128 (reader): Use trace_flag to enable scanner/parser debugging,
13129 instead of an adhoc scheme.
13130 * src/scan-gram.l: Remove trailing debugging code.
13132 2002-10-16 Paul Eggert <eggert@twinsun.com>
13134 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
13137 * NEWS: Officially drop support for building Bison with K&R C,
13138 since it didn't work anyway and it's not worth worrying about.
13139 * Makefile.maint (wget_files): Remove ansi2knr.c.
13140 (ansi2knr.c-url_prefix): Remove.
13141 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
13142 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13143 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13145 2002-10-15 Paul Eggert <eggert@twinsun.com>
13147 Stop using the "enum_" trick for K&R-style function definitions;
13148 it confused me, and I was the author! Instead, assume that people
13149 who want to use K&R C compilers (when using these modules in GCC,
13150 perhaps?) will run ansi2knr.
13152 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
13153 All uses of "enum_" changed to "enum ".
13154 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13155 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13157 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

13164 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
13165 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
13166 Use function prototypes; this removes the need for declaring
13167 static functions simply to provide their prototypes.
13168 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

13225 2002-10-14 Akim Demaille <akim@epita.fr>
13227 * tests/Makefile.am (maintainer-check-posix): New.
13229 2002-10-14 Akim Demaille <akim@epita.fr>
13231 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
13234 2002-10-14 Akim Demaille <akim@epita.fr>
13236 * src/tables.c (table_ninf_remap): base -> tab.
13237 Reported by Matt Rosing.
13239 2002-10-14 Paul Eggert <eggert@twinsun.com>
13241 * tests/action.at, tests/calc.at, tests/conflicts.at,
13242 tests/cxx-type.at, tests/headers.at, tests/input.at,
13243 tests/regression.at, tests/synclines.at, tests/torture.at:
13244 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
13245 so that the tests still work even if POSIXLY_CORRECT is set.
13246 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13248 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13249 for portability to K&R hosts. Fix typo: signed char is guaranteed
13250 only to 127, not to 128.
13251 * data/glr.c (yysigned_char): New type.
13252 * data/yacc.c (yysigned_char): Likewise.
13253 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13255 2002-10-13 Paul Eggert <eggert@twinsun.com>
13257 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13258 true due to limited range of data type" warning from GCC.
13260 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13261 by wrapping enum yytokentype's definition inside #ifndef
13262 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13264 2002-10-13 Akim Demaille <akim@epita.fr>
13266 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
13267 Un yy- yyrhs to avoid the name clash with the global YYRHS.
13269 2002-10-13 Akim Demaille <akim@epita.fr>
13271 * Makefile.maint: Update from Autoconf 2.54.
13272 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
13274 2002-10-13 Akim Demaille <akim@epita.fr>
13276 * src/print.c (print_state): Separate the list of solved conflicts
13277 from the other items.
13278 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
13280 2002-10-13 Akim Demaille <akim@epita.fr>
13282 Let nondeterministic skeletons be usable with deterministic
13285 With the patch, GAWK compiled by GCC without -O2 passes its test
13286 suite using a GLR parser driven by LALR tables. It fails with -O2
13287 because `struct stat' gives two different answers on my machine:
13288 88 (definition of an auto var) and later 96 (memset on this var).
13289 Hence the stack is badly corrumpted. The headers inclusion is to
13290 blame: if I move the awk.h inclusion before GLR's system header
13291 inclusion, the two struct stat have the same size.
13293 * src/tables.c (pack_table): Always create conflict_table.
13294 (token_actions): Always create conflict_list.
13295 * data/glr.c (YYFLAG): Remove, unused.
13297 2002-10-13 Akim Demaille <akim@epita.fr>
13299 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13301 (VALGRIND, GXX): New.
13302 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13303 * tests/bison.in: Run $PREBISON a pre-command.
13304 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
13305 (maintainer-check-g++): New.
13306 * Makefile.am (maintainer-check): New.
13308 2002-10-13 Akim Demaille <akim@epita.fr>
13310 * data/glr.c: Formatting changes.
13311 Tweak some trace messages to match yacc.c's.
13313 2002-10-13 Akim Demaille <akim@epita.fr>
13315 GLR parsers sometimes raise parse errors instead of performing the
13317 Reported by Charles-Henry de Boysson.
13319 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13320 check the length of the traces when %glr.
13321 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13323 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13325 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13326 (yyltype): Remove the yy prefix from the member names.
13327 (yytable): Complete its comment.
13328 (yygetLRActions): Map error action number from YYTABLE from
13330 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13331 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13332 not satisfying as we could compare an YYACTION computed from
13333 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13334 only value for error actions.
13335 (yyreportParseError): In verbose parse error messages, don't issue
13336 `error' in the list of expected tokens.
13337 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
13338 next action to perform to match glr.c's decoding.
13339 (yytable): Complete its comment.
13341 2002-10-13 Paul Eggert <eggert@twinsun.com>
13343 Fix problem reported by Henrik Grubbstroem in
13344 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
13345 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
13346 because the Bison parser reads the second action before reducing
13348 * src/scan-gram.l (rule_length): New static var.
13349 Use it to keep track of the rule length in the scanner, since
13350 we can't expect the parser to be in lock-step sync with the scanner.
13351 (handle_action_dollar, handle_action_at): Use this var.
13352 * tests/actions.at (Exotic Dollars): Test for the problem.
13354 2002-10-12 Paul Eggert <eggert@twinsun.com>
13356 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
13357 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
13358 Include <sys/time.h> when checking for clock_t and struct tms.
13359 Use same include order as source.
13360 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
13361 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
13363 * lib/timevar.c: Update copyright date and clarify comments.
13364 (get_time) [IN_GCC]: Keep the GCC version for reference.
13366 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13367 GCC version as of today, then merge Bison's changes.
13368 Change "GCC" to "Bison" in copyright notice. timevar.def's
13369 author is Akim, so change that too.
13371 * src/reader.c (grammar_current_rule_check):
13372 Don't worry about the default action if $$ is untyped.
13373 Prevents bogus warnings reported by Jim Gifford in
13374 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
13376 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
13377 * data/glr.c, data/lalr1.cc, data/yacc.c:
13378 Output token definitions before the first part of user declarations.
13379 Fixes compatibility problem reported by Jim Gifford for kbd in
13380 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
13382 2002-10-11 Paul Eggert <eggert@twinsun.com>
13384 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
13385 (yyparse): here. This undoes some of the 2002-07-25 change.
13386 Compatibility problem reported by Ralf S. Engelschall with
13387 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
13389 2002-10-11 Akim Demaille <akim@epita.fr>
13391 * tests/regression.at Characters Escapes): New.
13392 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and

13400 2002-10-10 Paul Eggert <eggert@twinsun.com>
13402 Portability fixes for bitsets; this also avoids several GCC
13405 * lib/abitset.c: Include <stddef.h>, for offsetof.
13406 * lib/lbitset.c: Likewise.
13408 * lib/abitset.c (abitset_bytes): Return a size that is aligned
13409 properly for vectors of objects. Do not assume that adding a
13410 header size to a multiple of a word size yields a value that is
13411 properly aligned for the whole union.
13412 * lib/bitsetv.c (bitsetv_alloc): Likewise.
13414 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
13415 unique names for structures.
13416 * lib/ebitset.c (ebitset_bytes): Likewise.
13417 * lib/lbitset.c (lbitset_bytes): Likewise.
13419 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

13424 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
13425 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
13426 to improve the type-checking that GCC can do.
13427 * lib/bitset.c (bitset_op4_cmp): Likewise.
13428 * lib/bitset_stats.c (bitset_stats_count,
13429 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

13437 bitset_stats_or_and_cmp): Likewise.
13438 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,

13444 * lib/ebitset.h: Likewise.
13445 * lib/lbitset.h: Likewise.
13447 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
13448 All instances of parameters of type enum bitset_opts are now of
13449 type enum_bitset_opts, to conform to the C Standard, and similarly
13450 for enum_bitset_type.
13451 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13452 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13454 Do not use "struct bitset_struct" to mean different things in
13455 different modules. Not only is this confusing, it violates
13456 the C Standard, which requires that structure types in different
13457 modules must be compatible if one is to be passed to the other.
13458 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13459 All instances of "struct bitset_struct *" replaced with "bitset".
13460 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
13461 (union bitset_union, struct abitset_struct, struct ebitset_struct,
13462 struct lbitset_struct, struct bitset_stats_struct): New types.
13463 All uses of struct bitset_struct changed to union bitset_union,

13468 struct bitset_struct): Remove.
13469 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
13470 bitset_struct): Remove.
13471 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
13474 Do not call a function of type T using a call that assumes the
13475 function is of a different type U. Standard C requires that a
13476 function must be called with a type that is compatible with its
13478 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13480 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13482 * lib/ebitset.c (PFV): Remove.
13483 * lib/lbitset.c (PFV): Likewise.
13484 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,

13491 (lbitset_vtable): Use them.
13493 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
13496 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
13498 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
13499 Use offsetof, for simplicity.
13501 2002-10-06 Paul Eggert <eggert@twinsun.com>
13503 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
13504 the same width as int. This reapplies a hunk of the 2002-08-12 patch
13505 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
13506 which was inadvertently undone by the 2002-09-30 patch.
13507 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
13508 the same width as int.
13510 2002-10-04 Paul Eggert <eggert@twinsun.com>
13514 * configure.ac (AC_INIT), NEWS: Increment version number.
13516 * doc/bison.texinfo: Minor spelling, grammar, and white space
13518 (Symbols): Mention that any negative value returned from yylex
13519 signifies end-of-input. Warn about negative chars. Mention
13520 the portable Standard C character set.
13522 The GNU coding standard says CFLAGS and YFLAGS are reserved
13523 for the installer to set.
13524 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
13525 * src/Makefile.am (AM_CFLAGS): Likewise.
13526 (AM_YFLAGS): Renamed from YFLAGS.
13528 Fix some MAX and MIN problems.

13530 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
13531 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
13532 * src/reader.c (reader): Use it.
13534 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
13535 POSIX 1003.1-2001 has removed fgrep.
13537 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
13539 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
13540 interpreted as signed.

13610 to BITSET_WINDEX_MAX.
13612 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
13613 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

13712 2002-09-06 Paul Eggert <eggert@twinsun.com>
13714 * doc/bison.texinfo (Conditions): Make explicit that the GPL
13715 exception applies only to yacc.c. This is a modification of a
13716 patch originally suggested by Akim Demaille.

13768 as int, and similarly for yyposn and YYINDEX.

13810 PROTOTYPES to check for prototypes, and "defined __STDC__" to
13813 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
13814 size_t; the old version tried to do this but casted improperly.
13815 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
13816 (bitset_test): Now returns int, not unsigned long.
13818 * lib/bitset_stats.c: Include "gettext.h".
13820 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
13821 name locals "index", as it generates unnecessary warnings on some

13860 to void, to avoid a GCC warning when --disable-nls is in effect.

13863 to minimize the number of warnings from xgettext.
13864 (handle_action_dollar, handle_action_at): Don't use isdigit,
13865 as it mishandles negative chars and it may not work as expected
13866 outside the C locale.
13868 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13869 this is a GCC extension and is not portable to other compilers.

13876 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
13879 * tests/regression.at: Do not use 'cc -c input.c -o input';
13880 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
13882 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13883 exit status as failure, not just exit status 1. Sun C exits
13884 with status 2 sometimes.
13886 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
13887 Use it for the two large tests.
13889 2002-08-02 Akim Demaille <akim@epita.fr>

13905 * src/print.c (print_results): Report rules never reduced.
13906 * tests/conflicts.at, tests/reduce.at: Adjust.
13908 2002-08-01 Akim Demaille <akim@epita.fr>

13933 2002-08-01 Akim Demaille <akim@epita.fr>

13942 (rule_list_t): Store rule_t *, not rule_number_t.

14051 different: save its reduction (accept) instead of having a state
14052 without any action (no shift or goto, no reduce).
14053 Note: the final state is now a ``regular'' state, i.e., the
14054 parsers now contain `reduce 0' as default reduction.
14055 Nevertheless, since they decide to `accept' when yystate =
14056 final_state, they still will not reduce rule 0.

14102 yycontrol without making too strong assumptions on the parser
14104 * src/output.c (prepare_tokens): Use the real 0th value of
14105 token_translations instead of `0'.
14106 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
14108 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
14109 for the time being: %locations ought to provide it to yyerror.
14111 2002-07-25 Akim Demaille <akim@epita.fr>
14113 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
14114 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
14115 * tests/regression.at (Web2c Actions): Adjust.
14117 2002-07-25 Akim Demaille <akim@epita.fr>

14123 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
14124 Iterate from 0 to nrules.
14125 Use rule_number_as_item_number and item_number_as_rule_number.
14126 Adjust to `derive' now containing possibly 0.
14127 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
14128 Handle the `- 1' part in rule numbers from/to item numbers.
14129 * src/conflicts.c (log_resolution): Fix the message which reversed
14131 * src/output.c (action_row): Initialize default_rule to -1.

15652 values of $$, $n and so forth, output invocation to b4_lhs_value,
15653 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
15654 Note: this patch partially drops `semantic-parser' support: it
15655 always does `rule_length - n', where semantic parsers ought to

15769 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15770 etc. instead of 10, 20, 30 (which was used to `jump' over error
15771 (256) and undefined (2)).
15773 2002-04-22 Akim Demaille <akim@epita.fr>

15810 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15811 full stderr, and strip it according to the bison options, instead
15812 of composing the error message from different bits.
15813 This makes it easier to check for several error messages.
15814 Adjust all the invocations.
15815 Add an invocation exercising the error token.
15816 Add an invocation demonstrating a stupid error message.
15817 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

15823 * src/gram.h, src/gram.c (error_token_number): Remove, use
15825 * src/reader.c (reader): Don't specify the user token number (2)

15828 * src/symtab.h: here.
15829 (state_t.number): Is a token_number_t.

15835 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15836 `user_token_number_max'.
15837 Output `undef_token_number'.

15858 * src/gram.h (item_number_t): New, the type of item numbers in
15859 RITEM. Note that it must be able to code symbol numbers as
15860 positive number, and the negation of rule numbers as negative

15877 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15878 of grammar file) bison is killed by my system, at 2000 (12Mb) bison

16034 Be sure to distinguish the initial from the final state.

16038 items properly set, there is no need for a special case when

16075 (reduce_output, dump_grammar): Adjust.
16076 * src/print.c (print_grammar): It is no longer needed to check for
16077 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

16080 2002-04-07 Akim Demaille <akim@epita.fr>
16082 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
16083 lacking `+ 1' to nrules, Bison reported as useless a token if it
16084 was used solely to set the precedence of the last rule...
16086 2002-04-07 Akim Demaille <akim@epita.fr>
16088 * data/bison.c++, data/bison.simple: Don't output the current file

16480 (output_skeleton): Don't look for the skeleton location, let m4 do
16482 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
16484 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
16485 (prepare): Given that for the time being changesyntax is not
16486 usable in M4, rename the muscles using `-' to `_'.

16532 * tests/regression.at (%nonassoc and eof): Adjust to newest

16607 (tab_extension): Remove.
16608 (compute_base_names): Compute the former, drop the latter.
16609 * src/output.c (prepare): Insert the muscles `output-infix', and
16611 * src/parse-skel.y (string, string.1): New.
16612 (section.header): Use it.
16613 (section.yacc): Remove.
16614 (prefix): Remove too.
16615 * src/scan-skel.l: Adjust.
16616 * src/bison.simple, src/bison.hairy: Adjust.
16618 2002-01-09 Akim Demaille <akim@epita.fr>
16620 * configure.in (WERROR_CFLAGS): Compute it.
16621 * src/Makefile.am (CFLAGS): Pass it.
16622 * tests/atlocal.in (CFLAGS): Idem.
16623 * src/files.c: Fix a few warnings.
16624 (get_extension_index): Remove, unused.
16626 2002-01-08 Akim Demaille <akim@epita.fr>
16628 * src/getargs.c (AS_FILE_NAME): New.
16629 (getargs): Use it to convert DOSish file names.
16630 * src/files.c (base_name): Rename as full_base_name to avoid
16631 clashes with `base_name ()'.
16632 (filename_split): New.
16633 (compute_base_names): N-th rewrite, using filename_split.
16635 2002-01-08 Akim Demaille <akim@epita.fr>
16637 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
16638 New, stolen from the Fileutils 4.1.
16639 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16640 * configure.in: Check for the presence of memrchr, and of its
16643 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16645 * lib/hash.h (__P): Added definition for this macro.
16646 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16647 BUILT_SOURCES, to ensure they are generated first.
16648 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16649 %error-verbose to allow bootstrapping with bison 1.30x.
16651 2002-01-06 Akim Demaille <akim@epita.fr>
16653 * src/reader.c (parse_braces): Don't fetch the next char, the
16654 convention is to fetch on entry.
16655 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16656 'switch' without a following semicolon.
16657 * tests/regression.at (braces parsing): New.
16659 2002-01-06 Akim Demaille <akim@epita.fr>
16661 Bison is dead wrong in its RR conflict reports.
16663 * tests/torture.at (GNU Cim Grammar): New.
16664 * src/conflicts.c (count_rr_conflicts): Fix.
16666 2002-01-06 Akim Demaille <akim@epita.fr>
16668 Creating package.m4 from configure.ac causes too many problems.
16670 * tests/Makefile.am (package.m4): Create it by hand,
16671 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16673 2002-01-06 Akim Demaille <akim@epita.fr>
16675 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16678 2002-01-04 Paul Eggert <eggert@twinsun.com>
16680 * doc/bison.texinfo (Debugging):
16681 Remove YYSTDERR; it's no longer defined or used.
16682 Also, s/cstdio.h/cstdio/.
16684 2002-01-03 Akim Demaille <akim@epita.fr>
16686 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16688 2002-01-03 Akim Demaille <akim@epita.fr>
16690 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16691 tracing code to --trace, wait for a better --trace option, with
16694 2002-01-03 Akim Demaille <akim@epita.fr>
16696 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16697 The ISO C++ standard is extremely clear about it: stderr is
16698 considered a macro, not a regular symbol (see table 94 `Header
16699 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16700 Therefore std:: does not apply to it. It still does with fprintf.
16701 Also, s/cstdio.h/cstdio/.
16703 2002-01-03 Akim Demaille <akim@epita.fr>
16705 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16706 for non system headers.
16708 2002-01-02 Akim Demaille <akim@epita.fr>
16710 Equip the skeleton chain with location tracking, runtime trace,
16711 pure parser and scanner.
16713 * src/parse-skel.y: Request a pure parser, locations, and prefix
16715 (%union): Having several members with the same type does not help
16716 type mismatches, simplify.
16717 (YYPRINT, yyprint): New.
16718 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16719 (skel_error): this.
16721 * src/scan-skel.l: Adjust to these changes.
16722 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16723 (LOCATION_PRINT, skel_control_t): New.
16725 2001-12-30 Akim Demaille <akim@epita.fr>
16727 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16728 replace `gb' with BLANKS.
16729 * src/scan-skel.l: Adjust.
16731 2001-12-30 Akim Demaille <akim@epita.fr>
16733 * src/system.h: We don't need nor want bcopy.
16734 Throw away MS-DOS crap: we don't need getpid.
16735 * configure.in: We don't need strndup. It was even causing
16736 problems: because Flex includes the headers *before* us,
16737 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16739 * lib/xstrndup.c: New.
16740 * src/scan-skel.l: Use it.
16741 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16742 * src/parse-skel.y: Use %directives instead of #defines.
16744 2001-12-30 Akim Demaille <akim@epita.fr>
16746 * src/skeleton.h: New.
16747 * src/output.c (output_parser, output_master_parser): Remove, dead
16749 * src/output.h (get_lines_number, actions_output, guards_output)
16750 (token_definitions_output): Prototype them.
16751 * src/parse-skel.y: Add the license notice.
16752 Include output.h and skeleton.h.
16753 (process_skeleton): Returns void, and takes a single parameter.
16754 * src/scan-skel.l: Add the license notice.
16755 Include skeleton.h.
16756 Don't use %option yylineno: it seems that then Flex imagines
16757 REJECT has been used, and therefore it won't reallocate its
16758 buffers (which makes no other sense to me than a bug). It results
16759 in warnings for `unused: yy_flex_realloc'.
16761 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16763 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16764 (MUSCLE_INSERT_PREFIX): ...to there.
16765 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16766 (MUSCLE_INSERT_PREFIX): Move from here...
16768 * src/bison.hairy: Add a section directive. Put braces around muscle
16769 names. This parser skeleton is still broken, but Bison should not
16770 choke on a bad muscle 'syntax'.
16771 * src/bison.simple: Add a section directive. Put braces around muscle
16774 * src/files.h (strsuffix, stringappend): Add declarations.
16775 (tab_extension): Add declaration.
16776 (short_base_name): Add declaration.
16778 * src/files.c (strsuffix, stringappend): No longer static. These
16779 functions are used in the skeleton parser.
16780 (tab_extension): New.
16781 (compute_base_names): Use the computations done in this function
16782 to guess if the generated parsers should have '.tab' in their
16784 (short_base_name): No longer static.
16786 * src/output.c (output_skeleton): New.
16787 (output): Disable call to output_master_parser, and give a try to
16788 a new skeleton handling system.
16789 (guards_output, actions_output): No longer static.
16790 (token_definitions_output, get_lines_number): No longer static.
16792 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16794 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16797 * src/parse-skel.y: New file.
16798 * src/scan-skel.l: New file.
16800 2001-12-29 Akim Demaille <akim@epita.fr>
16802 %name-prefix is broken.
16804 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16805 Adjust all dependencies.
16806 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16809 Renaming yylval but not yylloc is not consistent. Now we do.
16811 * src/bison.simple: Prefix yylloc if used.
16812 * doc/bison.texinfo (Decl Summary): Document that.
16814 2001-12-29 Akim Demaille <akim@epita.fr>
16816 * doc/bison.texinfo: Promote `%long-directive' over
16818 Remove all references to fixed-output-files, yacc is enough.
16820 2001-12-29 Akim Demaille <akim@epita.fr>
16822 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16823 user prologue. These are defaults.
16824 * tests/actions.at (Mid-rule actions): Make sure the user can
16825 define YYDEBUG and YYERROR_VERBOSE.
16827 2001-12-29 Akim Demaille <akim@epita.fr>
16829 * src/output.c (header_output): Don't forget to export YYLTYPE and
16831 * tests/headers.at (export YYLTYPE): New, make sure it does.
16832 * tests/regression.at (%union and --defines, Invalid CPP headers):
16834 * tests/headers.at: here.
16836 2001-12-29 Akim Demaille <akim@epita.fr>
16838 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16840 2001-12-29 Akim Demaille <akim@epita.fr>
16842 * tests/actions.at (Mid-rule actions): Output on a single line
16843 instead of several.
16845 2001-12-29 Akim Demaille <akim@epita.fr>
16847 * doc/bison.texinfo: Formatting changes.
16849 2001-12-29 Akim Demaille <akim@epita.fr>
16851 Don't store the token defs in a muscle, just be ready to output it
16852 on command. Now possible via `symbols'. Fixes a memory leak.
16854 * src/output.c (token_definitions_output): New.
16855 (output_parser, header_output): Use it.
16856 * src/reader.c (symbols_save): Remove.
16858 2001-12-29 Akim Demaille <akim@epita.fr>
16860 * src/bison.simple: Do not provide a default for YYSTYPE and
16861 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16864 2001-12-29 Akim Demaille <akim@epita.fr>
16866 Mid-rule actions are simply... ignored!
16868 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16869 the empty-rule associated to the dummy symbol, not to the host
16871 * tests/actions.at (Mid-rule actions): New.
16873 2001-12-29 Akim Demaille <akim@epita.fr>
16877 * src/reader.c (reader): Free grammar.
16879 2001-12-29 Akim Demaille <akim@epita.fr>
16883 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16884 since it allocates it for each state, although only one is needed.
16885 (allocate_storage): Do it here.
16887 2001-12-29 Akim Demaille <akim@epita.fr>
16889 * src/options.h, src/options.c (create_long_option_table): Rename
16891 (long_option_table_new): this, with a clearer prototype.
16892 (percent_table): Remove, unused,
16893 * src/getargs.c (getargs): Adjust.
16895 2001-12-29 Akim Demaille <akim@epita.fr>
16897 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16898 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16901 2001-12-29 Akim Demaille <akim@epita.fr>
16903 * src/lalr.c (build_relations): Rename `states' as `states1'.
16904 Sorry, I don't understand exactly what it is, no better name...
16906 2001-12-29 Akim Demaille <akim@epita.fr>
16908 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16909 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16910 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16913 2001-12-29 Akim Demaille <akim@epita.fr>
16915 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16918 2001-12-29 Akim Demaille <akim@epita.fr>
16920 * src/reader.c, src/reader.h (user_toknums): Remove.
16921 Adjust all users to use symbols[i]->user_token_number.
16923 2001-12-29 Akim Demaille <akim@epita.fr>
16925 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16926 Adjust all users to use symbols[i]->prec or ->assoc.
16928 2001-12-29 Akim Demaille <akim@epita.fr>
16930 * src/reader.c, src/reader.h (tags): Remove.
16931 Adjust all users to use symbols[i]->tag.
16933 2001-12-29 Akim Demaille <akim@epita.fr>
16935 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16937 * src/reader.c (packsymbols): Fill this table.
16939 * src/conflicts.c (resolve_sr_conflict): Adjust.
16940 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16942 Use symbols[i]->tag instead of tags[i].
16944 2001-12-29 Akim Demaille <akim@epita.fr>
16946 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16947 In addition, put a comment in there, to replace...
16948 * tests/regression.at (%union and C comments): Remove.
16950 2001-12-29 Akim Demaille <akim@epita.fr>
16952 * tests/regression.at (Web2c Actions): Blindly move the actual
16953 output as expected output. The contents *seem* right to me, but I
16954 can't pretend reading perfectly parser tables... Nonetheless, all
16955 the other tests pass correctly, the table look OK, even though the
16956 presence of `$axiom' is to be noted: AFAICS it is useless (but
16959 2001-12-29 Akim Demaille <akim@epita.fr>
16961 * src/reader.c (readgram): Don't add the rule 0 if there were no
16962 rules read. In other words, add it _after_ having performed
16963 grammar sanity checks.
16964 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16966 2001-12-29 Akim Demaille <akim@epita.fr>
16968 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16969 visible, and some states have now a different number.
16971 2001-12-29 Akim Demaille <akim@epita.fr>
16973 * src/reader.c (readgram): Bind the initial rule's lineno to that
16975 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16976 (Solved SR Conflicts): Adjust rule 0's line number.
16978 2001-12-29 Akim Demaille <akim@epita.fr>
16980 Fix the `GAWK Grammar' failure.
16982 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16983 the reductions of the first state which was mistakenly confused
16984 with the final state because precisely final_state was initialized
16986 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16987 now noticed by Bison.
16988 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16989 have a reduction on $default.
16991 2001-12-29 Akim Demaille <akim@epita.fr>
16993 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16995 * src/closure.c (print_closure): Likewise.
16996 * src/derives.c (print_derives): Likewise.
16997 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
17000 2001-12-29 Akim Demaille <akim@epita.fr>
17002 * src/lalr.c (lookaheads_print): New.
17003 (lalr): Call it when --trace-flag.
17004 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
17007 2001-12-29 Akim Demaille <akim@epita.fr>
17009 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17010 when walking through ritem, even via rule->rhs.
17011 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17012 (useful_production, useless_nonterminals): Likewise.
17013 (reduce_grammar_tables): Likewise, plus update nritems.
17014 * src/nullable.c (set_nullable): Likewise.
17015 * src/lalr.c (build_relations): Likewise.
17016 * tests/sets.at (Nullable): Adjust.
17017 Fortunately, now, the $axiom is no longer nullable.
17019 2001-12-29 Akim Demaille <akim@epita.fr>
17021 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
17023 * src/gram.c (ritem_longest_rhs): Likewise.
17024 * src/reduce.c (nonterminals_reduce): Likewise.
17025 * src/print_graph.c (print_graph): Likewise.
17026 * src/output.c (output_rule_data): Likewise.
17027 * src/nullable.c (set_nullable): Likewise.
17029 2001-12-29 Akim Demaille <akim@epita.fr>
17031 * src/output.c: Comment changes.
17033 2001-12-27 Paul Eggert <eggert@twinsun.com>
17035 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17036 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17037 Sparc, as they were causing more porting problems than the
17038 (minor) performance improvement was worth.
17040 Also, catch up with 1.31's YYSTD.
17042 2001-12-27 Akim Demaille <akim@epita.fr>
17044 * src/output.c (output_gram): Rely on nritems, not the
17045 0-sentinel. See below.
17046 Use -1 as separator, not 0.
17047 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17048 Rely on -1 as separator in yyrhs, instead of 0.
17049 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17050 twice `Now at end of input', therefore there are two lines less to
17053 2001-12-27 Akim Demaille <akim@epita.fr>
17055 * tests/regression.at (Unresolved SR Conflicts):
17056 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17059 2001-12-27 Akim Demaille <akim@epita.fr>
17061 * src/LR0.c (new_state): Recognize the final state by the fact it
17062 is reached by eoftoken.
17063 (insert_start_shifting_state, insert_eof_shifting_state)
17064 (insert_accepting_state, augment_automaton): Remove, since now
17065 these states are automatically computed from the initial state.
17066 (generate_states): Adjust.
17067 * src/print.c: When reporting a rule number to the user, substract
17068 1, so that the axiom rule is rule 0, and the first user rule is 1.
17069 * src/reduce.c: Likewise.
17070 * src/print_graph.c (print_core): For the time being, just as for
17071 the report, depend upon --trace-flags to dump the full set of
17073 * src/reader.c (readgram): Once the grammar read, insert the rule
17074 0: `$axiom: START-SYMBOL $'.
17075 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17076 number of the states has changed (the final state is no longer
17077 necessarily the last), catch up.
17079 2001-12-27 Akim Demaille <akim@epita.fr>
17081 Try to make the use of the eoftoken valid. Given that its value
17082 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
17083 is used instead of > 0 where appropriate, (ii), depend upon nritems
17084 instead of the 0-sentinel.
17086 * src/gram.h, src/gram.c (nritems): New.
17087 Expected to be duplication of nitems, but for the time being...
17088 * src/reader.c (packgram): Assert nritems and nitems are equal.
17089 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
17090 * src/closure.c (print_closure, print_fderives): Likewise.
17091 * src/gram.c (ritem_print): Likewise.
17092 * src/print.c (print_core, print_grammar): Likewise.
17093 * src/print_graph.c: Likewise.
17095 2001-12-27 Akim Demaille <akim@epita.fr>
17097 * src/main.c (main): If there are complains after grammar
17098 reductions, then output the report anyway if requested, then die.
17099 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
17100 * src/reader.c (eoftoken): New.
17101 (parse_token_decl): If the token being defined has value `0', it
17103 (packsymbols): No longer hack `tags' to insert `$' by hand.
17104 Be sure to preserve the value of the eoftoken.
17105 (reader): Make sure eoftoken is defined.
17106 Initialize nsyms to 0: now eoftoken is created just like the others.
17107 * src/print.c (print_grammar): Don't special case the eof token.
17108 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17109 lie anyway, albeit pleasant.
17110 * tests/calc.at: Exercise error messages with eoftoken.
17111 Change the grammar so that empty input is invalid.
17112 Adjust expectations.
17113 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
17115 2001-12-27 Akim Demaille <akim@epita.fr>
17117 * configure.in: Check the protos of strchr ans strspn.
17118 Replace strchr if needed.
17119 * src/system.h: Provide the protos of strchr, strspn and memchr if
17121 * lib/strchr.c: New.
17122 * src/reader.c (symbols_save): Use strchr.
17124 2001-12-27 Akim Demaille <akim@epita.fr>
17126 * src/print.c, src/print_graph.c (escape): New.
17127 Use it to quote the TAGS outputs.
17128 * src/print_graph.c (print_state): Now errors are in red, and
17129 reductions in green.
17130 Prefer high to wide: output the state number on a line of its own.
17132 2001-12-27 Akim Demaille <akim@epita.fr>
17134 * src/state.h, src/state.c (reductions_new): New.
17135 * src/LR0.c (set_state_table): Let all the states have a
17136 `reductions', even if reduced to 0.
17137 (save_reductions): Adjust.
17138 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

17148 * src/output.c (output_actions, action_row): Adjust.
17149 * src/conflicts.c (resolve_sr_conflict): Adjust.

17155 2001-12-27 Akim Demaille <akim@epita.fr>
17157 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
17158 * src/print.c: here.
17159 (lookaheadset, shiftset): New, used as additional storage by
17161 (print_results): Adjust.
17162 (print_shifts, print_gotos, print_errs): New, extracted from...
17163 (print_actions): here.
17164 * src/print_graph.c (print_actions): Remove dead code.
17166 2001-12-27 Akim Demaille <akim@epita.fr>
17168 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
17171 2001-12-27 Akim Demaille <akim@epita.fr>
17173 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
17174 (build_relations): Adjust.
17176 2001-12-27 Akim Demaille <akim@epita.fr>
17178 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
17181 2001-12-27 Akim Demaille <akim@epita.fr>
17183 * src/reader.c (packgram): Catch nitems overflows.
17185 2001-12-27 Akim Demaille <akim@epita.fr>
17187 * src/files.c, src/files.h (guard_obstack): Remove.
17188 * src/output.c (output): Adjust.
17189 * src/reader.c (parse_braces): New, factoring...
17190 (copy_action, copy_guard): these two which are renamed as...
17191 (parse_action, parse_guard): these.
17192 As a voluntary consequence, using braces around guards is now
17195 2001-12-27 Akim Demaille <akim@epita.fr>
17197 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17198 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17200 (symbol_list_new): Adjust.
17201 (copy_action): action_line is the first line, not the last.
17202 (copy_guard): Just as for actions, store the `action' only, not
17203 the switch/case/break flesh.
17204 Don't parse the user action that might follow the guard, let...
17205 (readgram): do it, i.e., now, there can be an action after a
17207 In other words the guard is just explicitly optional.
17208 (packgram): Adjust.
17209 * src/output.c (guards_output): New.
17210 (output_parser): Call it when needed.
17211 (output): Also free the guard and attrs obstacks.
17212 * src/files.c, src/files.h (obstack_save): Remove.
17213 (output_files): Remove.
17214 As a result, if one needs the former `.act' file, using an
17215 appropriate skeleton which requires actions and guards is now
17217 * src/main.c (main): Adjust.
17218 * tests/semantic.at: New.
17219 * tests/regression.at: Use `input.y' as input file name.
17220 Avoid 8+3 problems by requiring input.c when the test needs the
17223 2001-12-27 Akim Demaille <akim@epita.fr>
17225 * src/reader.c (symbol_list_new): Be sure to initialize all the
17228 2001-12-27 Akim Demaille <akim@epita.fr>
17230 All the hacks using a final pseudo state are now useless.
17232 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17233 * src/lalr.c (nLA): New.
17234 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17235 instead of lookaheadsp from the pseudo state (nstate + 1).
17237 2001-12-27 Akim Demaille <akim@epita.fr>
17239 * src/output.c (action_row, token_actions): Use a state_t instead
17240 of a integer, and nlookaheads instead of the following state's

17245 * src/conflicts.c (log_resolution, flush_shift)
17246 (resolve_sr_conflict, set_conflicts, solve_conflicts)
17247 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17248 (conflicts_print, print_reductions): Use a state_t instead of an
17249 integer when referring to a state.
17250 As much as possible, depend upon nlookaheads, instead of the
17251 `lookaheadsp' member of the following state (since lookaheads of
17252 successive states are successive, the difference between state n + 1
17253 and n served as the number of lookaheads for state n).
17254 * src/lalr.c (add_lookback_edge): Likewise.
17255 * src/print.c (print_core, print_actions, print_state)
17256 (print_results): Likewise.
17257 * src/print_graph.c (print_core, print_actions, print_state)
17258 (print_graph): Likewise.
17259 * src/conflicts.h: Adjust.
17261 2001-12-27 Akim Demaille <akim@epita.fr>
17263 * src/bison.hairy: Formatting/comment changes.
17265 Remove `register' indications.
17266 Add plenty of `static'.
17268 2001-12-27 Akim Demaille <akim@epita.fr>
17270 * src/output.c (prepare): Drop the muscle `ntbase' which
17271 duplicates ntokens.
17272 * src/bison.simple: Formatting/comment changes.
17273 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17274 is an undocumented synonym.
17276 2001-12-22 Akim Demaille <akim@epita.fr>
17278 * src/output.c (output_table_data): Change the prototype to use
17279 `int' for array ranges: some invocations do pass an int, not a
17281 Reported by Wayne Green.
17283 2001-12-22 Akim Demaille <akim@epita.fr>
17285 Some actions of web2c.y are improperly triggered.
17286 Reported by Mike Castle.
17288 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
17289 * tests/regression.at (Web2c): Rename as...
17290 (Web2c Report): this.
17291 (Web2c Actions): New.
17293 2001-12-22 Akim Demaille <akim@epita.fr>
17295 Reductions in web2c.y are improperly reported.
17296 Reported by Mike Castle.
17298 * src/conflicts.c (print_reductions): Fix.
17299 * tests/regression.at (Web2c): New.
17301 2001-12-18 Akim Demaille <akim@epita.fr>
17303 Some host fail on `assert (!"foo")', which expands to
17304 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17305 Reported by Nelson Beebee.
17307 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17308 `#define it_succeeded 0' and `assert (it_succeeded)'.
17310 2001-12-17 Marc Autret <autret_m@epita.fr>
17312 * src/bison.simple: Don't hard code the skeleton line and filename.
17313 * src/output.c (output_parser): Rename 'line' as 'output_line'.
17314 New line counter 'skeleton_line' (skeleton-line muscle).
17316 2001-12-17 Paul Eggert <eggert@twinsun.com>
17318 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17319 YYDEBUG must be defined to a nonzero value.
17321 * src/bison.simple (yytname): Do not assume that the user defines
17322 YYDEBUG to a properly parenthesized expression.
17324 2001-12-17 Akim Demaille <akim@epita.fr>
17326 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17327 nlookaheads is a new member.
17329 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17330 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
17333 2001-12-17 Akim Demaille <akim@epita.fr>
17335 * src/files.h, src/files.c (open_files, close_files): Remove.
17336 * src/main.c (main): Don't open/close files, nor invoke lex_free,
17338 * src/reader.c (reader): Do it.
17340 2001-12-17 Akim Demaille <akim@epita.fr>
17342 * src/conflicts.c (print_reductions): Formatting changes.
17344 2001-12-17 Akim Demaille <akim@epita.fr>
17346 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
17347 (flush_reduce): New.
17348 (resolve_sr_conflict): Adjust.
17350 2001-12-17 Akim Demaille <akim@epita.fr>
17352 * src/output.c (output_obstack): Be static and rename as...
17353 (format_obstack): this, to avoid any confusion with files.c's
17355 * src/reader.h (muscle_obstack): Move to...
17356 * src/output.h: here, since it's defined in output.c.
17358 2001-12-17 Akim Demaille <akim@epita.fr>
17360 * src/output.c (action_row, save_column, default_goto)
17361 (sort_actions, matching_state, pack_vector): Better variable
17364 2001-12-17 Akim Demaille <akim@epita.fr>
17366 * src/output.c: Various formatting changes.
17368 2001-12-17 Akim Demaille <akim@epita.fr>
17370 * src/files.c (output_files): Free the output_obstack.
17371 * src/main.c (main): Call print and print_graph conditionally.
17372 * src/print.c (print): Work unconditionally.
17373 * src/print_graph.c (print_graph): Work unconditionally.
17374 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17376 2001-12-16 Marc Autret <autret_m@epita.fr>
17378 * src/output.c (actions_output): Fix. When we use %no-lines,
17379 there is one less line per action.
17381 2001-12-16 Marc Autret <autret_m@epita.fr>
17383 * src/bison.simple: Remove a useless #line directive.
17384 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17385 * src/output.c (get_lines_number): New.
17386 (output_parser): Adjust, now takes care about the lines of a
17388 Fix line numbering.
17389 (actions_output): Computes the number of lines taken by actions.
17390 (output_master_parser): Insert new skeleton which is the name of
17391 the output parser file name.
17393 2001-12-15 Marc Autret <autret_m@epita.fr>
17395 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17397 2001-12-15 Marc Autret <autret_m@epita.fr>
17399 * src/output.c (output_gram): Keep track of the hairy one.
17401 2001-12-15 Akim Demaille <akim@epita.fr>
17403 Make `make distcheck' work.
17405 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17406 system.h which uses libgettext.h.
17408 2001-12-15 Akim Demaille <akim@epita.fr>
17410 * src/nullable.c (set_nullable): Useless rules must be skipped,
17411 otherwise, since we range over their symbols, we might look at a
17412 nonterminal which no longer ``exists'', i.e., it is not counted in
17413 `nvars', hence we overflow our arrays.
17415 2001-12-15 Akim Demaille <akim@epita.fr>
17417 The header can also be produced directly, without any obstack!
17420 * src/files.c, src/files.h (defines_obstack): Remove.
17421 (compute_header_macro): Global.
17422 (defines_obstack_save): Remove.
17423 * src/reader.c (parse_union_decl): No longer output to
17424 defines_obstack: its content can be found in the `stype' muscle
17426 (output_token_translations): Merge into...
17427 (symbols_output): this.
17429 (symbols_save): this.
17431 * src/output.c (header_output): New.
17434 2001-12-15 Akim Demaille <akim@epita.fr>
17436 * src/reader.c (parse_union_decl): Instead of handling two obstack
17437 simultaneously, use one to define the `stype' muscle, and use the
17438 value of the latter to fill defines_obstack.
17439 (copy_comment): Remove.
17440 (copy_comment2): Work for a single obstack.
17442 (copy_comment): this.
17444 2001-12-15 Akim Demaille <akim@epita.fr>
17446 * src/lex.c, src/lex.h (xgetc): No longer static.
17447 * src/reader.c (parse_union_decl): Revamp.
17449 2001-12-15 Akim Demaille <akim@epita.fr>
17451 Still making progress in separating Bison into (i) input, (ii)
17452 process, (iii) output: now we can directly output the parser file
17453 without using table_obstack at all.
17455 * src/files.c, src/files.h (table_obstack): Bye bye.
17456 (parser_file_name): New.
17457 * src/files.c (compute_output_file_names): Compute it.
17458 * src/output.c (actions_output, output_parser)
17459 (output_master_parser): To a file instead of an obstack.
17461 2001-12-15 Akim Demaille <akim@epita.fr>
17463 Attach actions to rules, instead of pre-outputting them to
17466 * src/gram.h (rule_t): action and action_line are new members.
17467 * src/reader.c (symbol_list): Likewise.
17468 (copy_action): Save the actions within the rule.
17469 (packgram): Save them in rule_table.
17470 * src/output.c (actions_output): New.
17471 (output_parser): Use it on `%%actions'.
17472 (output_rule_data): Don't free rule_table.
17474 (prepare): Don't save the `action' muscle.
17475 * src/bison.simple: s/%%action/%%actions/.
17477 2001-12-15 Akim Demaille <akim@epita.fr>
17479 * src/reader.c (copy_action): When --yacc, don't append a `;'
17480 to the user action: let it fail if lacking.
17481 Suggested by Arnold Robbins and Tom Tromey.
17483 2001-12-14 Akim Demaille <akim@epita.fr>
17485 * src/lex.c (literalchar): Simply return the char you decoded, non
17486 longer mess around with obstacks and int pointers.
17487 Adjust all callers.
17489 2001-12-14 Akim Demaille <akim@epita.fr>
17491 * src/lex.c (literalchar): Don't escape the special characters,
17492 just decode them, and keep them as char (before, eol was output as
17493 the 2 char string `\n' etc.).
17494 * src/output.c (output_rule_data): Use quotearg to output the
17497 2001-12-13 Paul Eggert <eggert@twinsun.com>
17499 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
17500 Do not infringe on the global user namespace when using C++.
17501 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
17502 All uses of `fprintf' and `stderr' changed.
17504 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
17506 2001-12-13 Akim Demaille <akim@epita.fr>
17508 The computation of nullable is broken: it doesn't handle empty
17511 * tests/torture.at (GNU AWK Grammar): New.
17512 * tests/sets.at (Nullable): New.
17513 * src/nullable.c (set_nullable): Instead of blindly looping over
17514 `ritems', loop over the rules, and then over their rhs's.
17516 Work around Autotest bugs.
17518 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
17519 frame, because Autotest understand lines starting with a `+' as
17520 traces from the shell. Then, they are not processed properly.
17521 Admittedly an Autotest bug, but we don't have time to wait for
17522 Autotest to catch up.
17523 * tests/regression.at (Broken Closure): Adjust to the new table
17526 * tests/sets.at: here.
17528 2001-12-13 Akim Demaille <akim@epita.fr>
17530 * src/closure.c (closure): Use nrules instead of playing tricks
17531 with BITS_PER_WORD.
17533 2001-12-13 Akim Demaille <akim@epita.fr>
17535 * src/print.c (print_actions): Output the handling of `$' as the
17536 traces do: shifting the token EOF. Before EOF was treated as a
17538 * tests/regression.at: Adjust some tests.
17539 * src/print_graph.c (print_core): Complete the set of items via
17540 closure. The next-to-final and final states are still unsatisfying,
17541 but that's to be addressed elsewhere.
17542 No longer output the rule numbers, but do output the state number.
17543 A single loop for the shifts + gotos is enough, but picked a
17544 distinct color for each.
17545 (print_graph): Initialize and finalize closure.
17547 2001-12-13 Akim Demaille <akim@epita.fr>
17549 * src/reader.c (readgram): Remove dead code, an strip useless
17551 (get_type): Remove, unused.
17553 2001-12-12 Akim Demaille <akim@epita.fr>
17555 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
17556 on that of lib/error.c.
17558 2001-12-12 Akim Demaille <akim@epita.fr>
17560 Some hosts don't like `/' in includes.
17562 * src/system.h: Include libgettext.h without qualifying the path.
17563 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
17566 2001-12-11 Marc Autret <autret_m@epita.fr>
17568 * src/output.c (output_parser): Remove useless muscle.
17570 2001-12-11 Marc Autret <autret_m@epita.fr>
17572 * src/bison.simple: Remove #line just before %%epilogue. It
17573 is now handled in ...
17574 * src/reader.c (read_additionnal_code): Add the output of a
17575 #line for the epilogue.
17577 2001-12-10 Marc Autret <autret_m@epita.fr>
17579 * src/reader.c (copy_definition): Re-use CPP-outed code which
17580 replace precedent remove.
17581 * src/bison.simple: Remove #line before %%prologue because
17582 %%input-line is wrong at this time.
17584 2001-12-10 Marc Autret <autret_m@epita.fr>
17586 * src/reader.c (symbols_output): Clean up.
17587 * src/output.c (output_gram, output): Clean up.
17589 2001-12-10 Akim Demaille <akim@epita.fr>
17591 * src/lalr.c (initialize_lookaheads): New. Extracted from...
17592 * src/LR0.c (set_state_table): here.
17593 * src/lalr.c (lalr): Call it.
17595 2001-12-10 Akim Demaille <akim@epita.fr>
17597 * src/state.h (shifts): Remove the `number' member: shifts are
17598 attached to state, hence no longer need to be labelled with a
17601 2001-12-10 Akim Demaille <akim@epita.fr>
17603 Now that states have a complete set of members, the linked list of
17604 shifts is useless: just fill directly the state's shifts member.
17606 * src/state.h (shifts): Remove the `next' member.
17607 * src/LR0.c (first_state, last_state): Remove.
17608 Adjust the callers.
17609 (augment_automaton): Don't look for the shifts that must be added
17610 a shift on EOF: it is those of the state we looked for! But now,
17611 since shifts are attached, it is no longer needed to looking
17612 merely by its id: its number.
17614 2001-12-10 Akim Demaille <akim@epita.fr>
17616 * src/LR0.c (augment_automaton): Better variable locality.
17617 Remove an impossible branch: if there is a state corresponding to
17618 the start symbol being shifted, then there is shift for the start
17619 symbol from the initial state.
17621 2001-12-10 Akim Demaille <akim@epita.fr>
17623 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17624 only when appropriate: when insert_start_shifting_state' is not
17626 * tests/regression.at (Rule Line Numbers): Adjust.
17628 2001-12-10 Akim Demaille <akim@epita.fr>
17630 * src/LR0.c (augment_automaton): Now that all states have shifts,
17631 merge the two cases addition shifts to the initial state.
17633 2001-12-10 Akim Demaille <akim@epita.fr>
17635 * src/lalr.c (set_state_table): Move to...
17637 * src/lalr.c (lalr): Don't call it...
17638 * src/LR0.c (generate_states): do it.
17639 * src/LR0.h (first_state): Remove, only the table is used.
17641 2001-12-10 Akim Demaille <akim@epita.fr>
17643 * src/LR0.h (first_shift, first_reduction): Remove.
17644 * src/lalr.c: Don't use first_shift: find shifts through the
17647 2001-12-10 Akim Demaille <akim@epita.fr>
17649 * src/LR0.c: Attach shifts to states as soon as they are
17651 * src/lalr.c (set_state_table): Instead of assigning shifts to
17652 state, just assert that the mapping was properly done.
17654 2001-12-10 Akim Demaille <akim@epita.fr>
17656 * src/LR0.c (insert_start_shift): Rename as...
17657 (insert_start_shifting_state): this.
17658 (insert_eof_shifting_state, insert_accepting_state): New.
17659 (augment_automaton): Adjust.
17660 Better locality of the variables.
17661 When looking if the start_symbol is shifted from the initial
17662 state, using `while (... symbol != start_symbol ...)' sounds
17663 better than `while (... symbol < start_symbol ...)': If fail
17664 to see how the order between symbols could be relevant!
17666 2001-12-10 Akim Demaille <akim@epita.fr>
17668 * src/getargs.h: Don't declare `spec_name_prefix' and
17669 `spec_file_prefix', declared by src/files.h.
17670 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17671 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17672 * src/output.c (prepare): Adjust.
17673 * src/reader.c (symbols_output): Likewise.
17674 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17676 2001-12-10 Akim Demaille <akim@epita.fr>
17678 * src/muscle_tab.c (muscle_init): NULL is a better default than
17681 2001-12-10 Akim Demaille <akim@epita.fr>
17683 * src/reader.c (reader): Calling symbols_output once is enough.
17685 2001-12-10 Akim Demaille <akim@epita.fr>
17687 Now that states have a complete set of members, the linked list of
17688 reductions is useless: just fill directly the state's reductions
17691 * src/state.h (struct reductions): Remove member `number' and
17693 * src/LR0.c (first_reduction, last_reduction): Remove.
17694 (save_reductions): Don't link the new reductions, store them in
17696 * src/lalr.c (set_state_table): No need to attach reductions to
17697 states, it's already done.
17698 * src/output.c (output_actions): No longer free the shifts, then
17699 the reductions, then the states: free all the states and their
17702 2001-12-10 Akim Demaille <akim@epita.fr>
17704 * src/options.c (OPTN, DRTV, BOTH): New.
17705 (option_table): Use them.
17707 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17708 the job of system.h.
17709 * src/options.c: Don't include stdio.h and xalloc.h for the same
17712 2001-12-10 Akim Demaille <akim@epita.fr>
17714 * src/output.c (output, prepare): Make sure the values of the
17715 muscles `action' and `prologue' are 0-terminated.
17717 2001-12-10 Akim Demaille <akim@epita.fr>
17719 Clean up GCC warnings.
17721 * src/reader.c (copy_action): `buf' is not used.
17722 (parse_skel_decl): Be static.
17723 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17724 * src/options.h (create_long_option_table): Have a real prototype.
17725 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
17726 (hash_delete_at): Return const void *.
17727 Adjust casts to preserve the const.
17729 2001-12-10 Akim Demaille <akim@epita.fr>
17731 * configure.in: Require 2.52g.
17732 M4 is not needed, but AUTOM4TE is.
17733 * m4/m4.m4: Remove.
17734 * tests/Makefile.am: Adjust.
17736 2001-12-10 Akim Demaille <akim@epita.fr>
17738 One structure for states is enough, even though theoretically
17739 there are LR(0) states and LALR(1) states.
17741 * src/lalr.h (state_t): Remove.
17742 (state_table): Be state_t **, not state_t *.
17743 * src/state.h (core, CORE_ALLOC): Rename as...
17744 (state_t, STATE_ALLOC): this.
17745 Add the LALR(1) members: shifts, reductions, errs.
17746 * src/LR0.c (state_table): Rename as...
17747 (state_hash): this, to avoid name clashes with the global
17749 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17750 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17752 2001-12-10 Akim Demaille <akim@epita.fr>
17754 Bison dumps core on bash.y.
17755 Reported by Pascal Bart.
17757 * src/warshall.c (bitmatrix_print): New.
17759 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17760 j must be the outer loop.
17761 * tests/regression.at (Broken Closure): New.
17763 2001-12-05 Akim Demaille <akim@epita.fr>
17765 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17767 Reported by Peter Hamorsky.
17769 2001-12-05 Akim Demaille <akim@epita.fr>
17771 * src/conflicts.c (err_table): Remove.
17772 (resolve_sr_conflict): Adjust.
17773 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17775 (state_t.reductions, state_t.shifts): this.
17777 2001-12-05 Akim Demaille <akim@epita.fr>
17779 * src/reduce.c (reduce_grammar_tables): No longer disable the
17780 removal of useless rules via CPP but via `if (0)', so that the
17781 compiler still check the code is valid.
17782 For instance, it should have noticed `rline' no longer exists: use
17783 the `line' member of rule_t.
17784 * src/gram.c (dummy, rline): Remove, unused.
17786 2001-12-05 Akim Demaille <akim@epita.fr>
17788 * src/output.c (pack_vector): Use assert, not berror.
17789 * src/main.c (berror): Remove, unused.
17791 2001-12-05 Akim Demaille <akim@epita.fr>
17793 New experimental feature: if --verbose --trace output all the
17794 items of a state, not only its kernel.
17796 * src/print.c (print_core): If `trace_flag', then invoke closure
17797 before outputting the items of the state (print_core is no longer
17798 a correct name them).
17799 (print_results): Invoke new_closure/free_closure if needed.
17801 2001-12-05 Akim Demaille <akim@epita.fr>
17803 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17804 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17805 (nitemset): for consistency with the rest of the project.
17807 2001-12-05 Akim Demaille <akim@epita.fr>
17809 * src/closure.c (print_closure): Improve.
17810 (closure): Use it for printing input and output.
17812 2001-12-05 Akim Demaille <akim@epita.fr>
17814 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17815 indexed by nonterminals.
17817 2001-12-05 Akim Demaille <akim@epita.fr>
17819 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17821 * src/warshall.h: Remove accidental duplication of the content.
17823 2001-12-05 Akim Demaille <akim@epita.fr>

17835 2001-12-05 Akim Demaille <akim@epita.fr>
17837 * src/output.c (action_row): De-obfuscate
17838 using the good o' techniques: arrays not pointers, variable
17839 locality, BITISSET, RESETBIT etc.
17841 2001-12-05 Akim Demaille <akim@epita.fr>
17843 Pessimize the code to simplify it: from now on, all the states
17844 have a valid SHIFTS, which NSHIFTS is possibly 0.
17846 * src/LR0.c (shifts_new): Be global and move to..
17847 * src/state.c, src/state.h: here.
17848 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17849 * src/print_graph: Adjust.
17851 2001-12-05 Akim Demaille <akim@epita.fr>
17853 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17854 * src/conflicts.c: Use it.
17855 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17856 incorrectly ``simplified''.
17858 2001-12-05 Akim Demaille <akim@epita.fr>
17860 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17861 using the good o' techniques: arrays not pointers, variable
17862 locality, BITISSET, RESETBIT etc.
17864 2001-12-05 Akim Demaille <akim@epita.fr>
17866 * src/state.h (SHIFT_SYMBOL): New.
17867 * src/conflicts.c: Use it to deobfuscate.
17869 2001-12-05 Akim Demaille <akim@epita.fr>
17871 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17872 (print_reductions): De-obfuscate using the good o' techniques:
17873 arrays not pointers, variable locality, BITISSET.
17875 2001-12-05 Akim Demaille <akim@epita.fr>
17877 * src/conflicts.c (print_reductions): Arrays, not pointers.
17880 2001-12-05 Akim Demaille <akim@epita.fr>

17888 2001-12-05 Akim Demaille <akim@epita.fr>
17890 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17892 2001-12-05 Akim Demaille <akim@epita.fr>
17894 * src/conflicts.c (print_reductions): Improve variable locality.
17896 2001-12-05 Akim Demaille <akim@epita.fr>
17898 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17899 * src/lalr.c: Use them.
17901 2001-12-05 Akim Demaille <akim@epita.fr>
17903 * src/LR0.c (augment_automaton): Formatting changes.
17904 Better variable locality.
17906 2001-12-05 Akim Demaille <akim@epita.fr>
17908 * src/lalr.c (matrix_print): New.
17909 (transpose): Use it.
17910 Use arrays instead of pointers.
17912 2001-12-05 Akim Demaille <akim@epita.fr>
17914 * src/lalr.c (maxrhs): Move to...
17915 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17916 * src/lalr.c (build_relations): Adjust.
17918 2001-12-05 Akim Demaille <akim@epita.fr>
17920 * src/lalr.c (transpose): Free the memory allocated to the
17921 argument, as it is replaced by the results by the unique caller.
17922 (build_relations): Merely invoke transpose: it handles the memory
17924 Improve variable locality.
17925 Avoid variables used as mere abbreviations.
17926 (compute_lookaheads): Use arrays instead of pointers.
17928 2001-12-05 Akim Demaille <akim@epita.fr>
17930 * src/lalr.c (initialize_F): Improve variable locality.
17931 Avoid variables used as mere abbreviations.
17933 2001-12-05 Akim Demaille <akim@epita.fr>
17935 * src/derives.c (print_derives): Display the ruleno.
17936 * src/lalr.c (initialize_F, transpose): Better variable locality
17937 to improve readability.
17938 Avoid variables used as mere abbreviations.
17940 2001-12-05 Akim Demaille <akim@epita.fr>
17942 * src/lalr.c (traverse): Use arrays instead of pointers.
17944 2001-12-05 Akim Demaille <akim@epita.fr>
17946 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17947 the handling of squeue.
17948 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17950 2001-12-05 Akim Demaille <akim@epita.fr>
17952 Because useless nonterminals are now kept alive (instead of being
17953 `destroyed'), we now sometimes examine them, and store information
17954 related to them. Hence we need to know their number, and adjust
17955 memory allocations.
17957 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17959 * src/LR0.c (allocate_itemsets): The memory allocated to
17960 `symbol_count' was used for two different purpose: once to count
17961 the number of occurrences of each symbol, and later reassigned to
17962 `shift_symbol', containing the symbol that can be shifted from a
17964 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17966 (new_itemsets): Allocate `shift_symbol' here.
17967 (allocate_itemsets): symbol_count includes useless nonterminals.
17968 Make room for them.
17969 (free_storage): Use `free', not `XFREE', for pointers that cannot
17972 2001-12-05 Akim Demaille <akim@epita.fr>
17974 * src/nullable.c (set_nullable): Deobfuscate the handling of
17976 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17978 2001-12-05 Akim Demaille <akim@epita.fr>
17980 * src/gram.c, src/gram.h (ritem_print): New.
17981 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17982 (This useless function was defined only to work around VMS linkers
17983 that can't handle compilation units with variables only).
17984 * src/reduce.c (dump_grammar): Use it to trace the construction of
17987 2001-12-04 Paul Eggert <eggert@twinsun.com>
17989 * src/bison.simple (union yyalloc): Change member names
17990 to be the same as the stack names.
17991 (yyparse): yyptr is now union yyalloc *, not char *.
17992 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17993 and may generate better code on some machines.
17994 (yystpcpy): Use prototype if __STDC__ is defined, not just
17995 if __cplusplus is defined.
17997 2001-11-30 Akim Demaille <akim@epita.fr>
17999 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
18000 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
18001 Gettext doesn't compile cleanly, and dies with -Werror.
18002 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
18003 Include WARNING_CFLAGS here.
18004 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
18005 before being defined.
18007 2001-11-27 Paul Eggert <eggert@twinsun.com>
18009 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18010 First arg is int, not unsigned.
18011 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
18012 (SIZE_MAX, UINT_MAX): New macros.
18013 (quotearg_n_options): Abort if N is negative.
18014 Avoid overflow check on hosts where size_t is 64 bits and int
18015 is 32 bits, as overflow is impossible there.
18016 Fix off-by-one typo that caused unnecessary reallocation.
18018 2001-11-29 Paul Eggert <eggert@twinsun.com>
18020 Name space cleanup in generated parser.
18022 * doc/bison.texinfo (Bison Parser): Discuss system headers
18023 and their effect on the user name space.
18025 * src/bison.simple:
18026 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
18027 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18028 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18030 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18031 on user names when possible.
18033 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18034 Simplify test for whather <alloca.h> exists.
18036 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18038 (<stdio.h>): Include if YYDEBUG.
18040 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18041 ! defined (yyoverflow) && ! defined (yymemcpy).
18043 (yymemcpy, yyparse): Rename local variables as needed so that
18044 they all begin with 'yy'.
18046 (yystrlen, yystpcpy): New functions.
18048 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18051 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18052 instead of relying on string.h functions. Use YYSTACK_ALLOC
18053 and YYSTACK_FREE instead of malloc and free.
18055 2001-11-30 Akim Demaille <akim@epita.fr>
18057 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18058 before their first uses.
18059 (YYBISON, YYPURE): Move to the top of the output.
18061 2001-11-30 Akim Demaille <akim@epita.fr>
18063 * tests/reduce.at (Useless Nonterminals): Fix.
18065 2001-11-30 Akim Demaille <akim@epita.fr>
18067 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
18068 if body instead of `;' to pacify GCC's warnings.
18070 2001-11-30 Akim Demaille <akim@epita.fr>
18072 Instead of mapping the LHS of unused rules to -1, keep the LHS
18073 valid, but flag the rules as invalid.
18075 * src/gram.h (rule_t): `useful' is a new member.
18076 * src/print.c (print_grammar): Adjust.
18077 * src/derives.c (set_derives): Likewise.
18078 * src/reader.c (packgram, reduce_output): Likewise.
18079 * src/reduce.c (reduce_grammar_tables): Likewise.
18080 * tests/reduce.at (Underivable Rules, Useless Rules): New.
18082 2001-11-30 Akim Demaille <akim@epita.fr>
18084 * src/reduce.c (reduce_output): Formatting changes.
18085 * src/print.c (print_results, print_grammar): Likewise.
18086 * tests/regression.at (Rule Line Numbers)
18087 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
18089 2001-11-30 Akim Demaille <akim@epita.fr>
18091 * src/reduce.c (nonterminals_reduce): Instead of throwing away
18092 useless nonterminals, move them at the end of the symbol arrays.
18093 (reduce_output): Adjust.
18094 * tests/reduce.at (Useless Nonterminals): Adjust.
18096 2001-11-30 Akim Demaille <akim@epita.fr>
18098 * src/reduce.c: Various comment/formatting changes.
18099 (nonterminals_reduce): New, extracted from...
18100 (reduce_grammar_tables): here.
18101 (reduce_grammar): Call nonterminals_reduce.
18103 2001-11-29 Paul Eggert <eggert@twinsun.com>
18105 * src/bison.simple (YYSTACK_REALLOC): Remove.
18106 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
18107 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
18109 (union yyalloc): New type.
18110 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
18111 an arbitrary restriction on hosts where size_t is wider than int.
18113 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18114 a parser stack overflow. Allocate just one block of memory for all
18115 three stacks, instead of allocating three blocks; this typically is
18116 faster and reduces fragmentation.
18118 Do not limit the number of items in the stack to a value that fits
18119 in 'int', as this is an arbitrary limit on hosts with 64-bit
18120 size_t and 32-bit int.

19984 introduces a guaranteed SEGV for semantic parsers.

20204 (done): Rename as...
20205 (output_files): this.
20206 Use `obstack_save'.
20207 * src/main.c (main): Don't use `atexit' to register `done', since
20208 it no longer has to remove tmp files, just call `output_files'
20209 when there are no errors.
20211 2000-11-02 Akim Demaille <akim@epita.fr>
20213 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

20217 2000-11-02 Akim Demaille <akim@epita.fr>
20219 Remove the last uses of mktemp and unlink/delete.
20221 * src/files.c (fdefines, ftable): Removed.

20283 called after `//' or `/*' was read.
20284 (copy_comment, copy_definition, parse_union_decl, copy_action)
20285 (copy_guard): Adjust.
20287 2000-10-16 Akim Demaille <akim@epita.fr>
20289 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

20313 2000-10-04 Akim Demaille <akim@epita.fr>
20315 When a literal string is used to define two different tokens,
20316 `bison -v' segfaults.
20317 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
20319 * tests/regression.m4: New file.
20320 Include the core of the sample provided by Piotr Gackiewicz.
20321 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
20324 2000-10-04 Akim Demaille <akim@epita.fr>
20326 * src/reader.c (parse_expect_decl): Keep `count' within the size
20330 2000-10-02 Paul Eggert <eggert@twinsun.com>
20332 * bison.s1 (yyparse): Assign the default value

20341 2000-10-02 Akim Demaille <akim@epita.fr>
20343 * src/derives.c, src/print.c, src/reduce.c: To ease the
20344 translation, move some `\n' out of the translated strings.
20346 2000-10-02 Akim Demaille <akim@epita.fr>
20348 The location tracking mechanism is precious for parse error
20349 messages. Nevertheless, it is enabled only when `@n' is used in
20350 the grammar, which is a different issue (you can use it in error
20351 message, but not in the grammar per se). Therefore, there should
20352 be another means to enable it.
20354 * src/getargs.c (getargs): Support `--locations'.
20355 (usage): Report it.
20356 * src/getargs.h (locationsflag): Export it.
20357 * src/lex.c (percent_table): Support `%locations'.
20358 * src/reader.c (yylsp_needed): Remove this variable, now replaced
20359 with `locationsflag'.
20360 * doc/bison.texinfo: Document `--locations' and `%locations'.
20362 * tests/calc.m4: Test it.
20364 For regularity of the names, replace each
20365 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20366 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20367 In addition replace each `flag' with `_flag'.
20369 2000-10-02 Akim Demaille <akim@epita.fr>
20371 Also test parse error messages, including with YYERROR_VERBOSE.
20373 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20375 Use it to check the computations.
20376 Use it to check `nonassoc' is honored.
20377 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20378 `--yyerror-verbose'.
20379 (_AT_CHECK_CALC): Adjust to this option.

20382 2000-10-02 Akim Demaille <akim@epita.fr>
20384 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20385 the latter demonstrates a flaw in the handling of non debugging
20386 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20387 was used in order to simplify:
20403 unfortunately this leads to a CPP conflict when
20404 `--name-prefix=foo' is used since it produces `#define yydebug
20407 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20408 (YYDPRINTF): New macro.
20410 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20412 Also test `--verbose', `--defines' and `--name-prefix'.

20416 Improve the readability of the produced parsers.
20418 * src/bison.s1: Formatting changes.
20419 Improve the comment related to the `$' mark.
20420 (yydefault): Don't fall through to `yyresume': `goto' there.
20421 * src/output.c (output_parser): When the `$' is met, skip the end
20423 New variable, `number_of_dollar_signs', to check there's exactly
20424 one `$' in the parser skeleton.
20426 2000-10-02 Akim Demaille <akim@epita.fr>
20428 * lib/xstrdup.c: New file, from the fileutils.
20429 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
20430 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
20431 instead of strlen + xmalloc + strcpy.
20432 * src/symtab.c (copys): Remove, use xstrdup instead.
20434 2000-10-02 Akim Demaille <akim@epita.fr>
20436 * src/gram.h (associativity): New enum type which replaces the
20437 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
20438 `right_assoc', `left_assoc' and `non_assoc'.
20439 Adjust all dependencies.
20440 * src/reader.c: Formatting changes.
20441 (LTYPESTR): Don't define it, use it as a literal in
20442 `reader_output_yylsp'.
20443 * src/symtab.h (symbol_class): New enum type which replaces the
20444 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
20445 `sunknown', `stoken and `snterm'.
20447 2000-10-02 Akim Demaille <akim@epita.fr>
20449 * src/getargs.c (fixed_outfiles): Rename as...
20450 (yaccflag): for consistency and accuracy.
20451 Adjust dependencies.
20453 2000-10-02 Akim Demaille <akim@epita.fr>
20455 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20456 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20457 difficult and introduced a lot of core dump. It turns out that
20458 Bison used an implementation of `xmalloc' based on `calloc', and
20459 at various places it does depend upon the initialization to 0. I
20460 have not tried to isolate the pertinent places, and all the former
20461 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
20462 someone should address this issue.
20464 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
20465 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

20475 * src/system.h: Include `assert.h'.
20477 2000-10-02 Akim Demaille <akim@epita.fr>
20479 * src/state.h (nstates, final_state, first_state, first_shift)
20480 (first_reduction): Move their exportation from here...

20482 Adjust dependencies.
20483 * src/getargs.c (statisticsflag): New variable.
20484 Add support for `--statistics'.

20521 Propagate its inclusion.
20522 * src/reduce.c: Topological sort and other formatting changes.
20523 (bool, TRUE, FALSE): Move their definition to...

20526 2000-10-02 Akim Demaille <akim@epita.fr>
20528 * src/files.c: Formatting changes.
20529 (tryopen, tryclose, openfiles): Rename as...
20530 (xfopen, xfclose, open_files): this.
20531 (stringappend): static.

20555 * src/lalr.c: Formatting changes, topological sorting etc.
20557 2000-10-02 Akim Demaille <akim@epita.fr>
20559 * src/output.c (token_actions): Introduce a temporary array,
20560 YYDEFACT, that makes it possible for this function to use
20561 output_short_table.
20563 2000-10-02 Akim Demaille <akim@epita.fr>
20565 `user_toknums' is output as a `short[]' in `output.c', while it is
20566 defined as a `int[]' in `reader.c'. For consistency with the
20567 other output tables, `user_toknums' is now defined as a table of

20611 * src/system.h: Define PARAMS.

20832 Change the handling of @s so that they behave exactly like $s.
20833 There is now a pseudo variable @$ (readble and writable), location
20834 of the lhs of the rule (by default ranging from the location of

20871 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

21550 declaration to allow a multi-character symbol as an alias.
21551 (parse_thong_decl): New function.

21564 an invalid character. Do not abort.
21565 (read_declarations, copy_guard, copy_action): Use
21566 printable_version to avoid unprintable characters in printed output.

21595 always contain the token. This includes growing the token
21596 buffer while reading an integer.
21597 (parse_percent_token): Replaced if-else statement with percent_table.
21598 (parse_percent_token): Added % declarations as another
21599 way to specify the flags -n, -l, and -r. Also added hooks for
21600 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21601 major changes to files.c.
21602 (lex) Retain in the incoming stream a character following
