ChangeLog

   1 2002-07-30  Akim Demaille  <akim@epita.fr>
   2
   3         In verbose parse error message, don't report `error' as an
   4         expected token.
   5         * tests/actions.at (Printers and Destructors): Adjust.
   6         * tests/calc.at (Calculator $1): Adjust.
   7         * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
   8         error message, do not report the parser accepts the error token in
   9         that state.
  10
  11 2002-07-30  Akim Demaille  <akim@epita.fr>
  12
  13         Normalize conflict related messages.
  14
  15         * src/complain.h, src/complain.c (warn, complain): New.
  16         * src/conflicts.c (conflicts_print): Use them.
  17         (conflict_report_yacc): New, extracted from...
  18         (conflicts_print): here.
  19         * tests/conflicts.at, tests/existing.at: Adjust.
  20
  21 2002-07-30  Akim Demaille  <akim@epita.fr>
  22
  23         Report rules which are never reduced by the parser: those hidden
  24         by conflicts.
  25
  26         * src/LR0.c (save_reductions): Don't make the final state too
  27         different: save its reduction (accept) instead of having a state
  28         without any action (no shift or goto, no reduce).
  29         Note: the final state is now a ``regular'' state, i.e., the
  30         parsers now contain `reduce 0' as default reduction.
  31         Nevertheless, since they decide to `accept' when yystate =
  32         final_state, they still will not reduce rule 0.
  33         * src/print.c (print_actions, print_reduction): Adjust.
  34         * src/output.c (action_row): Track reduced rules.
  35         (token_actions): Report rules never reduced.
  36         * tests/conflicts.at, tests/regression.at: Adjust.
  37
  38 2002-07-30  Akim Demaille  <akim@epita.fr>
  39
  40         `stage' was accidently included in a previous patch.
  41         Initiate its autoconfiscation.
  42
  43         * configure.in: Look for malloc.h and sys/times.h.
  44         * src/main.c (stage): Adjust.
  45         Report only when trace_flag.
  46
  47 2002-07-29  Akim Demaille  <akim@epita.fr>
  48
  49         * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not
  50         state_number_t.
  51         (errs_t): symbol_t*, not symbol_number_t.
  52         (reductions_t): rule_t*, not rule_number_t.

  62         (endtoken, accept): these.
  63         * src/reader.c (reader): Set endtoken's default tag to "$end".
  64         Set undeftoken's tag to "$undefined" instead of "$undefined.".
  65         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
  66         Adjust.
  67
  68 2002-07-29  Akim Demaille  <akim@epita.fr>
  69
  70         * src/reduce.c (reduce_grammar): When the language is empty,
  71         complain about the start symbol, not the axiom.
  72         Use its location.
  73         * tests/reduce.at (Empty Language): New.
  74
  75 2002-07-26  Akim Demaille  <akim@epita.fr>

  78         yycontrol without making too strong assumptions on the parser
  79         itself.
  80         * src/output.c (prepare_tokens): Use the real 0th value of
  81         token_translations instead of `0'.
  82         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
  83         visible here.
  84         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
  85         for the time being: %locations ought to provide it to yyerror.
  86
  87 2002-07-25  Akim Demaille  <akim@epita.fr>
  88
  89         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1158         grammar.
1159         Use more modest sizes, as for the time being the parser does not
1160         release memory, and therefore the process swallows a huge amount
1161         of memory.
1162
1163         * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the

1174         eccentricities.

1186         * src/reader.c  (parse_action): Don't store directly into the
1187         rule's action member: return the action as a string.
1188         Don't require `rule_length' as an argument: compute it.

1198         (readgram): here.
1199         Remove `xaction', `first_rhs': useless.

1235         use it in...

1249
1250         Remove `%thong' support as it is undocumented, unused, duplicates
1251         `%token's job, and creates useless e-mail traffic with people who
1252         want to know what it is, why it is undocumented, unused, and

1739         * src/reader.c (token_translations_init): 256 is now the default
1740         value for the error token, i.e., it will be assigned another
1741         number if the user assigned 256 to one of her tokens.
1742         (reader): Don't force 256 to error.
1743         * doc/bison.texinfo (Symbols): Adjust.
1744         * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
1745         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
1746         etc. instead of 10, 20, 30 (which was used to `jump' over error
1747         (256) and undefined (2)).
1748
1749 2002-04-22  Akim Demaille  <akim@epita.fr>
1750
1751         Propagate more token_number_t.
1752
1753         * src/gram.h (token_number_as_item_number)
1754         (item_number_as_token_number): New.
1755         * src/output.c (GENERATE_OUTPUT_TABLE): New.
1756         Use it to create output_item_number_table and
1757         output_token_number_table.
1758         * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,
1759         * src/lex.c, src/nullable.c, src/output.c, src/print.c,
1760         * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,
1761         * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.
1762
1763 2002-04-22  Akim Demaille  <akim@epita.fr>
1764
1765         * src/output.h, src/output.c (get_lines_number): Remove.
1766
1767 2002-04-19  Akim Demaille  <akim@epita.fr>
1768
1769         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
1770         as Lex/Flex'.
1771         (Debugging): More details about enabling the debugging features.
1772         (Table of Symbols): Describe $$, $n, @$, and @n.
1773         Suggested by Tim Josling.
1774
1775 2002-04-19  Akim Demaille  <akim@epita.fr>
1776
1777         * doc/bison.texinfo: Remove the uses of the obsolete @refill.
1778
1779 2002-04-10  Akim Demaille  <akim@epita.fr>
1780
1781         * src/system.h: Rely on HAVE_LIMITS_H.
1782         Suggested by Paul Eggert.
1783
1784 2002-04-09  Akim Demaille  <akim@epita.fr>
1785
1786         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
1787         full stderr, and strip it according to the bison options, instead
1788         of composing the error message from different bits.
1789         This makes it easier to check for several error messages.
1790         Adjust all the invocations.
1791         Add an invocation exercising the error token.
1792         Add an invocation demonstrating a stupid error message.
1793         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
1794         Adjust the tests.
1795         Error message are for stderr, not stdout.
1796
1797 2002-04-09  Akim Demaille  <akim@epita.fr>
1798
1799         * src/gram.h, src/gram.c (error_token_number): Remove, use
1800         errtoken->number.
1801         * src/reader.c (reader): Don't specify the user token number (2)
1802         for $undefined, as it uselessly prevents using it.
1803         * src/gram.h (token_number_t): Move to...
1804         * src/symtab.h: here.
1805         (state_t.number): Is a token_number_t.
1806         * src/print.c, src/reader.c: Use undeftoken->number instead of
1807         hard coded 2.
1808         (Even though this 2 is not the same as above: the number of the
1809         undeftoken remains being 2, it is its user token number which
1810         might not be 2).
1811         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
1812         `user_token_number_max'.
1813         Output `undef_token_number'.
1814         * data/bison.simple, data/bison.c++: Use them.
1815         Be sure to map invalid yylex return values to
1816         `undef_token_number'.  This saves us from gratuitous SEGV.
1817
1818         * tests/conflicts.at (Solved SR Conflicts)
1819         (Unresolved SR Conflicts): Adjust.
1820         * tests/regression.at (Web2c Actions): Adjust.
1821
1822 2002-04-08  Akim Demaille  <akim@epita.fr>
1823
1824         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
1825         Adding #line.
1826         Remove the duplicate `typedefs'.
1827         (RhsNumberType): Fix the declaration and various other typos.
1828         Use __ofile__.
1829         * data/bison.simple: Use __ofile__.
1830         * src/scan-skel.l: Handle __ofile__.
1831
1832 2002-04-08  Akim Demaille  <akim@epita.fr>
1833
1834         * src/gram.h (item_number_t): New, the type of item numbers in
1835         RITEM.  Note that it must be able to code symbol numbers as
1836         positive number, and the negation of rule numbers as negative
1837         numbers.
1838         Adjust all dependencies (pretty many).
1839         * src/reduce.c (rule): Remove this `short *' pointer: use
1840         item_number_t.
1841         * src/system.h (MINSHORT, MAXSHORT): Remove.
1842         Include `limits.h'.
1843         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
1844         (shortcpy): Remove.
1845         (MAXTABLE): Move to...
1846         * src/output.c (MAXTABLE): here.
1847         (prepare_rules): Use output_int_table to output rhs.
1848         * data/bison.simple, data/bison.c++: Adjust.
1849         * tests/torture.at (Big triangle): Move the limit from 254 to
1850         500.
1851         * tests/regression.at (Web2c Actions): Ajust.
1852
1853         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
1854         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
1855         passes, but produces negative #line number, once fixed, GCC is
1856         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
1857         C), it passes.
1858         * src/state.h (state_h): Code input lines on ints, not shorts.
1859
1860 2002-04-08  Akim Demaille  <akim@epita.fr>
1861
1862         * src/reduce.c (reduce_grammar): First reduce the nonterminals,
1863         and then the grammar.
1864
1865 2002-04-08  Akim Demaille  <akim@epita.fr>
1866
1867         * src/system.h: No longer using strndup.

1872         * src/output.c (output_table_data): Return the longest number.
1873         (prepare_tokens): Output `token_number_max').
1874         * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
1875         New.
1876         Use them to define yy_token_number_type/TokenNumberType.
1877         Use this type for yytranslate.
1878         * tests/torture.at (Big triangle): Push the limit from 124 to
1879         253.

1889
1890         * src/gram.h, src/gram.c (nitems): Remove, it is an alias of
1891         nritems.
1892         Adjust dependencies.
1893

1951
1952         * src/gram.h (rule_s): prec and precsym are now pointers
1953         to the bucket giving the priority/associativity.
1954         Member `associativity' removed: useless.

1984         * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
1985
1986 2002-04-07  Akim Demaille  <akim@epita.fr>
1987
1988         Be sure never to walk through RITEMS, but use only data related to
1989         the rules themselves. RITEMS should be banished.
1990
1991         * src/output.c (output_token_translations): Rename as...
1992         (prepare_tokens): this.
1993         In addition to `translate', prepare the muscles `tname' and

1995         (output_rule_data): this.
1996         Remove, and move the remainder of its outputs into...
1997         (prepare_rules): this new routines, which also merges content from

2006
2007         * src/LR0.c (new_state): Display `nstates' as the name of the
2008         newly created state.
2009         Adjust to initialize first_state and last_state if needed.
2010         Be sure to distinguish the initial from the final state.
2011         (new_states): Create the itemset of the initial state, and use
2012         new_state.
2013         * src/closure.c (closure): Now that the initial state has its
2014         items properly set, there is no need for a special case when
2015         creating `ruleset'.
2016
2017         As a result, now the rule 0, reducing to $axiom, is visible in the
2018         outputs.  Adjust the test suite.
2019
2020         * tests/conflicts.at (Solved SR Conflicts)
2021         (Unresolved SR Conflicts): Adjust.

2029         * src/output.c (output_gram): Likewise.
2030
2031 2002-04-07  Akim Demaille  <akim@epita.fr>

2034         bucket.
2035         Adjust all dependencies.
2036         * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
2037         `number' of the buckets too.
2038         * src/gram.h: Include `symtab.h'.
2039         (associativity): Move to...
2040         * src/symtab.h: here.
2041         No longer include `gram.h'.
2042
2043 2002-04-07  Akim Demaille  <akim@epita.fr>
2044
2045         * src/gram.h, src/gram.c (rules_rhs_length): New.

2050         the end of `rules', and count them out of `nrules'.
2051         (reduce_output, dump_grammar): Adjust.
2052         * src/print.c (print_grammar): It is no longer needed to check for
2053         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
2054         * tests/reduce.at (Reduced Automaton): New test.
2055
2056 2002-04-07  Akim Demaille  <akim@epita.fr>
2057
2058         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
2059         lacking `+ 1' to nrules, Bison reported as useless a token if it
2060         was used solely to set the precedence of the last rule...
2061
2062 2002-04-07  Akim Demaille  <akim@epita.fr>
2063
2064         * data/bison.c++, data/bison.simple: Don't output the current file
2065         name in #line, to avoid useless diffs between two identical
2066         outputs under different names.
2067
2068 2002-04-07  Akim Demaille  <akim@epita.fr>
2069
2070         * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
2071         Normalize loops to using `< nrules + 1', not `<= nrules'.
2072

2359         causing more problems than it was curing, since it didn't work

2437         More is certainly needed.
2438
2439 2002-02-05  Akim Demaille  <akim@epita.fr>
2440
2441         Give a try to M4 as a back end.
2442
2443         * lib/readpipe.c: New, from wdiff.
2444         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
2445         BISON_HAIRY.
2446         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
2447         specific values.  Now it is m4 that performs the lookup.
2448         * src/parse-skel.y: Remove.
2449         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
2450         * src/output.c (actions_output, guards_output)
2451         (token_definitions_output): No longer keeps track of the output
2452         line number, hence remove the second argument.
2453         (guards_output): Check against the guard member of a rule, not the
2454         action member.
2455         Adjust callers.
2456         (output_skeleton): Don't look for the skeleton location, let m4 do
2457         that.
2458         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
2459         file will be used.
2460         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2461         (prepare): Given that for the time being changesyntax is not
2462         usable in M4, rename the muscles using `-' to `_'.
2463         Define `defines_flag', `output_parser_name' and `output_header_name'.
2464         * src/output.h (actions_output, guards_output)
2465         (token_definitions_output): Adjust prototypes.
2466         * src/scan-skel.l: Instead of scanning the skeletons, it now
2467         processes the output of m4: `__oline__' and `#output'.
2468         * data/bison.simple: Adjust to be used by M4(sugar).
2469         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2470         to date.
2471         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
2472         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
2473         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
2474         shamelessly stolen from CVS Autoconf.
2475
2476 2002-02-05  Akim Demaille  <akim@epita.fr>
2477
2478         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
2479         * configure.in: Check for the declarations of free and malloc.
2480         * src/muscle_tab.c: Adjust.
2481
2482 2002-02-05  Akim Demaille  <akim@epita.fr>
2483
2484         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
2485         which have no values.
2486
2487 2002-02-05  Akim Demaille  <akim@epita.fr>
2488
2489         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
2490         * data/: here.
2491
2492 2002-01-29  Paul Eggert  <eggert@twinsun.com>
2493
2494         * src/bison.simple (YYSIZE_T): Do not define merely because
2495         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
2496         On some platforms, <alloca.h> does not declare YYSTD (size_t).
2497
2498 2002-01-27  Akim Demaille  <akim@epita.fr>
2499
2500         Fix `%nonassoc and eof'.
2501
2502         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
2503         which were not properly copied!  Replace
2504         memcpy (res->errs, src->errs, src->nerrs);
2505         with
2506         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2507         !!!
2508         * tests/regression.at (%nonassoc and eof): Adjust to newest
2509         Autotest: `.' is not in the PATH.
2510
2511 2002-01-27  Akim Demaille  <akim@epita.fr>
2512
2513         * tests/sets.at (AT_EXTRACT_SETS): New.
2514         (Nullable): Use it.
2515         (Firsts): New.
2516
2517 2002-01-26  Akim Demaille  <akim@epita.fr>
2518
2519         * tests/actions.at, tests/calc.at, tests/headers.at,
2520         * tests/torture.at: Adjust to the newest Autotest which no longer
2521         forces `.' in the PATH.
2522
2523 2002-01-25  Akim Demaille  <akim@epita.fr>
2524
2525         * tests/regression.at (%nonassoc and eof): New.
2526         Suggested by Robert Anisko.
2527
2528 2002-01-24  Akim Demaille  <akim@epita.fr>
2529
2530         Bison dumps core when trying to complain about broken input files.
2531         Reported by Cris van Pelt.
2532
2533         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2534         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2535         into...
2536         (Invalid inputs): Strengthen: exercise parse_percent_token.
2537
2538 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
2539
2540         * src/Makefile.am: Add bison.c++.
2541         * src/bison.c++: New skeleton.
2542
2543 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
2544
2545         * po/it.po: New.
2546
2547 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
2548
2549         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2550
2551 2002-01-20  Marc Autret  <marc@gnu.org>
2552
2553         * src/files.c (compute_output_file_names): Fix
2554
2555 2002-01-20  Marc Autret  <marc@gnu.org>
2556
2557         * tests/output.at: New test.
2558         * src/files.c (compute_base_names): Don't map extensions when
2559         the YACC flag is set, use defaults.
2560         Reported by Evgeny Stambulchik.
2561
2562 2002-01-20  Marc Autret  <marc@gnu.org>
2563
2564         * src/system.h: Need to define __attribute__ away for non-GCC
2565         compilers as well (i.e. the vendor C compiler).
2566         Suggested by Albert Chin-A-Young.
2567
2568 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
2569
2570         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2571         canonical definition.
2572         * src/system.h: Use the canonical definition for PARAMS (avoids
2573         a conflict with the macro from lib/hash.h).
2574
2575 2002-01-11  Akim Demaille  <akim@epita.fr>
2576
2577         * configure.in: Use AC_FUNC_STRNLEN.
2578         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2579
2580 2002-01-09  Akim Demaille  <akim@epita.fr>
2581
2582         * src/files.c, src/files.h (output_infix): New.
2583         (tab_extension): Remove.
2584         (compute_base_names): Compute the former, drop the latter.
2585         * src/output.c (prepare): Insert the muscles `output-infix', and
2586         `output-suffix'.
2587         * src/parse-skel.y (string, string.1): New.
2588         (section.header): Use it.
2589         (section.yacc): Remove.
2590         (prefix): Remove too.
2591         * src/scan-skel.l: Adjust.
2592         * src/bison.simple, src/bison.hairy: Adjust.
2593
2594 2002-01-09  Akim Demaille  <akim@epita.fr>
2595
2596         * configure.in (WERROR_CFLAGS): Compute it.
2597         * src/Makefile.am (CFLAGS): Pass it.
2598         * tests/atlocal.in (CFLAGS): Idem.
2599         * src/files.c: Fix a few warnings.
2600         (get_extension_index): Remove, unused.
2601
2602 2002-01-08  Akim Demaille  <akim@epita.fr>
2603
2604         * src/getargs.c (AS_FILE_NAME): New.
2605         (getargs): Use it to convert DOSish file names.
2606         * src/files.c (base_name): Rename as full_base_name to avoid
2607         clashes with `base_name ()'.
2608         (filename_split): New.
2609         (compute_base_names): N-th rewrite, using filename_split.
2610
2611 2002-01-08  Akim Demaille  <akim@epita.fr>
2612
2613         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
2614         New, stolen from the Fileutils 4.1.
2615         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
2616         * configure.in: Check for the presence of memrchr, and of its
2617         prototype.
2618
2619 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
2620
2621         * lib/hash.h (__P): Added definition for this macro.
2622         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
2623         BUILT_SOURCES, to ensure they are generated first.
2624         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
2625         %error-verbose to allow bootstrapping with bison 1.30x.
2626
2627 2002-01-06  Akim Demaille  <akim@epita.fr>
2628
2629         * src/reader.c (parse_braces): Don't fetch the next char, the
2630         convention is to fetch on entry.
2631         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
2632         'switch' without a following semicolon.
2633         * tests/regression.at (braces parsing): New.
2634
2635 2002-01-06  Akim Demaille  <akim@epita.fr>
2636
2637         Bison is dead wrong in its RR conflict reports.
2638
2639         * tests/torture.at (GNU Cim Grammar): New.
2640         * src/conflicts.c (count_rr_conflicts): Fix.
2641
2642 2002-01-06  Akim Demaille  <akim@epita.fr>
2643
2644         Creating package.m4 from configure.ac causes too many problems.
2645
2646         * tests/Makefile.am (package.m4): Create it by hand,
2647         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2648
2649 2002-01-06  Akim Demaille  <akim@epita.fr>
2650
2651         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
2652         skeleton.h.
2653
2654 2002-01-04  Paul Eggert  <eggert@twinsun.com>
2655
2656         * doc/bison.texinfo (Debugging):
2657         Remove YYSTDERR; it's no longer defined or used.
2658         Also, s/cstdio.h/cstdio/.
2659
2660 2002-01-03  Akim Demaille  <akim@epita.fr>
2661
2662         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2663
2664 2002-01-03  Akim Demaille  <akim@epita.fr>
2665
2666         * src/parse-skel.y (process_skeleton): Don't bind the parser's
2667         tracing code to --trace, wait for a better --trace option, with
2668         args.
2669
2670 2002-01-03  Akim Demaille  <akim@epita.fr>
2671
2672         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
2673         The ISO C++ standard is extremely clear about it: stderr is
2674         considered a macro, not a regular symbol (see table 94 `Header
2675         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
2676         Therefore std:: does not apply to it.  It still does with fprintf.
2677         Also, s/cstdio.h/cstdio/.
2678
2679 2002-01-03  Akim Demaille  <akim@epita.fr>
2680
2681         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2682         for non system headers.
2683
2684 2002-01-02  Akim Demaille  <akim@epita.fr>
2685
2686         Equip the skeleton chain with location tracking, runtime trace,
2687         pure parser and scanner.
2688
2689         * src/parse-skel.y: Request a pure parser, locations, and prefix
2690         renaming.
2691         (%union): Having several members with the same type does not help
2692         type mismatches, simplify.
2693         (YYPRINT, yyprint): New.
2694         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
2695         (skel_error): this.
2696         Handle locations.
2697         * src/scan-skel.l: Adjust to these changes.
2698         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
2699         (LOCATION_PRINT, skel_control_t): New.
2700
2701 2001-12-30  Akim Demaille  <akim@epita.fr>
2702
2703         * src/parse-skel.y: Get rid of the shift/reduce conflict:
2704         replace `gb' with BLANKS.
2705         * src/scan-skel.l: Adjust.
2706
2707 2001-12-30  Akim Demaille  <akim@epita.fr>
2708
2709         * src/system.h: We don't need nor want bcopy.
2710         Throw away MS-DOS crap: we don't need getpid.
2711         * configure.in: We don't need strndup.  It was even causing
2712         problems: because Flex includes the headers *before* us,
2713         _GNU_SOURCE is not defined by config.h, and therefore strndup was
2714         not visible.
2715         * lib/xstrndup.c: New.
2716         * src/scan-skel.l: Use it.
2717         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
2718         * src/parse-skel.y: Use %directives instead of #defines.
2719
2720 2001-12-30  Akim Demaille  <akim@epita.fr>
2721
2722         * src/skeleton.h: New.
2723         * src/output.c (output_parser, output_master_parser): Remove, dead
2724         code.
2725         * src/output.h (get_lines_number, actions_output, guards_output)
2726         (token_definitions_output): Prototype them.
2727         * src/parse-skel.y: Add the license notice.
2728         Include output.h and skeleton.h.
2729         (process_skeleton): Returns void, and takes a single parameter.
2730         * src/scan-skel.l: Add the license notice.
2731         Include skeleton.h.
2732         Don't use %option yylineno: it seems that then Flex imagines
2733         REJECT has been used, and therefore it won't reallocate its
2734         buffers (which makes no other sense to me than a bug).  It results
2735         in warnings for `unused: yy_flex_realloc'.
2736
2737 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
2738
2739         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2740         (MUSCLE_INSERT_PREFIX): ...to there.
2741         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2742         (MUSCLE_INSERT_PREFIX): Move from here...
2743
2744         * src/bison.hairy: Add a section directive.  Put braces around muscle
2745         names.  This parser skeleton is still broken, but Bison should not
2746         choke on a bad muscle 'syntax'.
2747         * src/bison.simple: Add a section directive.  Put braces around muscle
2748         names.
2749
2750         * src/files.h (strsuffix, stringappend): Add declarations.
2751         (tab_extension): Add declaration.
2752         (short_base_name): Add declaration.
2753
2754         * src/files.c (strsuffix, stringappend): No longer static.  These
2755         functions are used in the skeleton parser.
2756         (tab_extension): New.
2757         (compute_base_names): Use the computations done in this function
2758         to guess if the generated parsers should have '.tab' in their
2759         names.
2760         (short_base_name): No longer static.
2761
2762         * src/output.c (output_skeleton): New.
2763         (output): Disable call to output_master_parser, and give a try to
2764         a new skeleton handling system.
2765         (guards_output, actions_output): No longer static.
2766         (token_definitions_output, get_lines_number): No longer static.
2767
2768         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
2769
2770         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
2771         parse-skel.y.
2772
2773         * src/parse-skel.y: New file.
2774         * src/scan-skel.l: New file.
2775
2776 2001-12-29  Akim Demaille  <akim@epita.fr>
2777
2778         %name-prefix is broken.
2779
2780         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
2781         Adjust all dependencies.
2782         * tests/headers.at (export YYLTYPE): Strengthen this test: use
2783         %name-prefix.
2784
2785         Renaming yylval but not yylloc is not consistent.  Now we do.
2786
2787         * src/bison.simple: Prefix yylloc if used.

2789
2790 2001-12-29  Akim Demaille  <akim@epita.fr>
2791
2792         * doc/bison.texinfo: Promote `%long-directive' over
2793         `%long_directive'.
2794         Remove all references to fixed-output-files, yacc is enough.
2795
2796 2001-12-29  Akim Demaille  <akim@epita.fr>
2797
2798         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
2799         user prologue.  These are defaults.
2800         * tests/actions.at (Mid-rule actions): Make sure the user can
2801         define YYDEBUG and YYERROR_VERBOSE.
2802
2803 2001-12-29  Akim Demaille  <akim@epita.fr>
2804
2805         * src/output.c (header_output): Don't forget to export YYLTYPE and
2806         yylloc.
2807         * tests/headers.at (export YYLTYPE): New, make sure it does.
2808         * tests/regression.at (%union and --defines, Invalid CPP headers):
2809         Move to...
2810         * tests/headers.at: here.
2811
2812 2001-12-29  Akim Demaille  <akim@epita.fr>
2813
2814         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2815
2816 2001-12-29  Akim Demaille  <akim@epita.fr>
2817
2818         * tests/actions.at (Mid-rule actions): Output on a single line
2819         instead of several.
2820
2821 2001-12-29  Akim Demaille  <akim@epita.fr>
2822
2823         * doc/bison.texinfo: Formatting changes.
2824
2825 2001-12-29  Akim Demaille  <akim@epita.fr>
2826
2827         Don't store the token defs in a muscle, just be ready to output it
2828         on command.  Now possible via `symbols'.  Fixes a memory leak.
2829
2830         * src/output.c (token_definitions_output): New.
2831         (output_parser, header_output): Use it.
2832         * src/reader.c (symbols_save): Remove.
2833
2834 2001-12-29  Akim Demaille  <akim@epita.fr>
2835
2836         * src/bison.simple: Do not provide a default for YYSTYPE and
2837         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
2838         default.
2839
2840 2001-12-29  Akim Demaille  <akim@epita.fr>
2841
2842         Mid-rule actions are simply... ignored!
2843
2844         * src/reader.c (readgram): Be sure to attach mid-rule actions to
2845         the empty-rule associated to the dummy symbol, not to the host
2846         rule.
2847         * tests/actions.at (Mid-rule actions): New.
2848
2849 2001-12-29  Akim Demaille  <akim@epita.fr>
2850
2851         Memory leak.
2852
2853         * src/reader.c (reader): Free grammar.
2854
2855 2001-12-29  Akim Demaille  <akim@epita.fr>
2856
2857         Memory leak.
2858
2859         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
2860         since it allocates it for each state, although only one is needed.
2861         (allocate_storage): Do it here.
2862
2863 2001-12-29  Akim Demaille  <akim@epita.fr>
2864
2865         * src/options.h, src/options.c (create_long_option_table): Rename
2866         as...
2867         (long_option_table_new): this, with a clearer prototype.
2868         (percent_table): Remove, unused,
2869         * src/getargs.c (getargs): Adjust.
2870
2871 2001-12-29  Akim Demaille  <akim@epita.fr>
2872
2873         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
2874         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
2875         as states.
2876
2877 2001-12-29  Akim Demaille  <akim@epita.fr>
2878
2879         * src/lalr.c (build_relations): Rename `states' as `states1'.
2880         Sorry, I don't understand exactly what it is, no better name...
2881
2882 2001-12-29  Akim Demaille  <akim@epita.fr>
2883

2886         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
2887         as rules.
2888
2889 2001-12-29  Akim Demaille  <akim@epita.fr>
2890
2891         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2892         ago.
2893
2894 2001-12-29  Akim Demaille  <akim@epita.fr>
2895
2896         * src/reader.c, src/reader.h (user_toknums): Remove.
2897         Adjust all users to use symbols[i]->user_token_number.
2898
2899 2001-12-29  Akim Demaille  <akim@epita.fr>
2900
2901         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2902         Adjust all users to use symbols[i]->prec or ->assoc.
2903
2904 2001-12-29  Akim Demaille  <akim@epita.fr>
2905
2906         * src/reader.c, src/reader.h (tags): Remove.
2907         Adjust all users to use symbols[i]->tag.
2908
2909 2001-12-29  Akim Demaille  <akim@epita.fr>
2910
2911         * src/gram.h, src/gram.c (symbols): New, similar to state_table
2912         and rule_table.
2913         * src/reader.c (packsymbols): Fill this table.
2914         Drop sprec.
2915         * src/conflicts.c (resolve_sr_conflict): Adjust.
2916         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2917         single table.
2918         Use symbols[i]->tag instead of tags[i].
2919
2920 2001-12-29  Akim Demaille  <akim@epita.fr>
2921
2922         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
2923         In addition, put a comment in there, to replace...
2924         * tests/regression.at (%union and C comments): Remove.
2925
2926 2001-12-29  Akim Demaille  <akim@epita.fr>
2927
2928         * tests/regression.at (Web2c Actions): Blindly move the actual
2929         output as expected output.  The contents *seem* right to me, but I
2930         can't pretend reading perfectly parser tables...  Nonetheless, all
2931         the other tests pass correctly, the table look OK, even though the
2932         presence of `$axiom' is to be noted: AFAICS it is useless (but
2933         harmless).
2934
2935 2001-12-29  Akim Demaille  <akim@epita.fr>
2936
2937         * src/reader.c (readgram): Don't add the rule 0 if there were no
2938         rules read.  In other words, add it _after_ having performed
2939         grammar sanity checks.
2940         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2941
2942 2001-12-29  Akim Demaille  <akim@epita.fr>
2943
2944         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2945         visible, and some states have now a different number.
2946
2947 2001-12-29  Akim Demaille  <akim@epita.fr>
2948
2949         * src/reader.c (readgram): Bind the initial rule's lineno to that
2950         of the first rule.
2951         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2952         (Solved SR Conflicts): Adjust rule 0's line number.
2953
2954 2001-12-29  Akim Demaille  <akim@epita.fr>
2955
2956         Fix the `GAWK Grammar' failure.
2957
2958         * src/LR0.c (final_state): Initialize to -1 so that we do compute
2959         the reductions of the first state which was mistakenly confused
2960         with the final state because precisely final_state was initialized
2961         to 0.
2962         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
2963         now noticed by Bison.
2964         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
2965         have a reduction on $default.
2966
2967 2001-12-29  Akim Demaille  <akim@epita.fr>
2968
2969         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2970         rule line numbers.
2971         * src/closure.c (print_closure): Likewise.
2972         * src/derives.c (print_derives): Likewise.
2973         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
2974         now.
2975
2976 2001-12-29  Akim Demaille  <akim@epita.fr>
2977
2978         * src/lalr.c (lookaheads_print): New.
2979         (lalr): Call it when --trace-flag.
2980         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2981         are dumped.
2982
2983 2001-12-29  Akim Demaille  <akim@epita.fr>
2984
2985         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
2986         when walking through ritem, even via rule->rhs.
2987         * src/reduce.c (dump_grammar, useful_production, reduce_output)
2988         (useful_production, useless_nonterminals): Likewise.
2989         (reduce_grammar_tables): Likewise, plus update nritems.
2990         * src/nullable.c (set_nullable): Likewise.
2991         * src/lalr.c (build_relations): Likewise.
2992         * tests/sets.at (Nullable): Adjust.
2993         Fortunately, now, the $axiom is no longer nullable.
2994
2995 2001-12-29  Akim Demaille  <akim@epita.fr>
2996
2997         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2998         the 0-sentinel.
2999         * src/gram.c (ritem_longest_rhs): Likewise.
3000         * src/reduce.c (nonterminals_reduce): Likewise.

3002         * src/output.c (output_rule_data): Likewise.
3003         * src/nullable.c (set_nullable):  Likewise.

3005 2001-12-29  Akim Demaille  <akim@epita.fr>
3006
3007         * src/output.c: Comment changes.
3008
3009 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3010
3011         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3012         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3013         Sparc, as they were causing more porting problems than the
3014         (minor) performance improvement was worth.
3015
3016         Also, catch up with 1.31's YYSTD.
3017
3018 2001-12-27  Akim Demaille  <akim@epita.fr>
3019
3020         * src/output.c (output_gram): Rely on nritems, not the
3021         0-sentinel.  See below.
3022         Use -1 as separator, not 0.
3023         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3024         Rely on -1 as separator in yyrhs, instead of 0.
3025         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3026         twice `Now at end of input', therefore there are two lines less to
3027         expect.
3028
3029 2001-12-27  Akim Demaille  <akim@epita.fr>
3030
3031         * tests/regression.at (Unresolved SR Conflicts):
3032         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3033         below.
3034
3035 2001-12-27  Akim Demaille  <akim@epita.fr>
3036
3037         * src/LR0.c (new_state): Recognize the final state by the fact it
3038         is reached by eoftoken.
3039         (insert_start_shifting_state, insert_eof_shifting_state)
3040         (insert_accepting_state, augment_automaton): Remove, since now
3041         these states are automatically computed from the initial state.
3042         (generate_states): Adjust.
3043         * src/print.c: When reporting a rule number to the user, substract
3044         1, so that the axiom rule is rule 0, and the first user rule is 1.
3045         * src/reduce.c: Likewise.
3046         * src/print_graph.c (print_core): For the time being, just as for
3047         the report, depend upon --trace-flags to dump the full set of
3048         items.
3049         * src/reader.c (readgram): Once the grammar read, insert the rule
3050         0: `$axiom: START-SYMBOL $'.
3051         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3052         number of the states has changed (the final state is no longer
3053         necessarily the last), catch up.
3054
3055 2001-12-27  Akim Demaille  <akim@epita.fr>
3056
3057         Try to make the use of the eoftoken valid.  Given that its value
3058         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3059         is used instead of > 0 where appropriate, (ii), depend upon nritems
3060         instead of the 0-sentinel.
3061
3062         * src/gram.h, src/gram.c (nritems): New.
3063         Expected to be duplication of nitems, but for the time being...
3064         * src/reader.c (packgram): Assert nritems and nitems are equal.
3065         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3066         * src/closure.c (print_closure, print_fderives): Likewise.
3067         * src/gram.c (ritem_print): Likewise.
3068         * src/print.c (print_core, print_grammar): Likewise.
3069         * src/print_graph.c: Likewise.
3070
3071 2001-12-27  Akim Demaille  <akim@epita.fr>
3072
3073         * src/main.c (main): If there are complains after grammar
3074         reductions, then output the report anyway if requested, then die.
3075         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3076         * src/reader.c (eoftoken): New.
3077         (parse_token_decl): If the token being defined has value `0', it
3078         is the eoftoken.
3079         (packsymbols): No longer hack `tags' to insert `$' by hand.
3080         Be sure to preserve the value of the eoftoken.
3081         (reader): Make sure eoftoken is defined.
3082         Initialize nsyms to 0: now eoftoken is created just like the others.
3083         * src/print.c (print_grammar): Don't special case the eof token.
3084         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3085         lie anyway, albeit pleasant.
3086         * tests/calc.at: Exercise error messages with eoftoken.
3087         Change the grammar so that empty input is invalid.
3088         Adjust expectations.
3089         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3090
3091 2001-12-27  Akim Demaille  <akim@epita.fr>
3092
3093         * configure.in: Check the protos of strchr ans strspn.
3094         Replace strchr if needed.
3095         * src/system.h: Provide the protos of strchr, strspn and memchr if
3096         missing.
3097         * lib/strchr.c: New.
3098         * src/reader.c (symbols_save): Use strchr.
3099
3100 2001-12-27  Akim Demaille  <akim@epita.fr>
3101
3102         * src/print.c, src/print_graph.c (escape): New.
3103         Use it to quote the TAGS outputs.
3104         * src/print_graph.c (print_state): Now errors are in red, and
3105         reductions in green.
3106         Prefer high to wide: output the state number on a line of its own.
3107
3108 2001-12-27  Akim Demaille  <akim@epita.fr>
3109
3110         * src/state.h, src/state.c (reductions_new): New.
3111         * src/LR0.c (set_state_table): Let all the states have a
3112         `reductions', even if reduced to 0.
3113         (save_reductions): Adjust.
3114         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
3115         * src/print.c (print_reductions, print_actions): Adjust.
3116         * src/output.c (action_row): Adjust.

3121         * src/LR0.c (set_state_table): Let all the states have an errs,
3122         even if reduced to 0.
3123         * src/print.c (print_errs, print_reductions): Adjust.
3124         * src/output.c (output_actions, action_row): Adjust.
3125         * src/conflicts.c (resolve_sr_conflict): Adjust.
3126
3127 2001-12-27  Akim Demaille  <akim@epita.fr>

3133         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3134         * src/print.c: here.
3135         (lookaheadset, shiftset): New, used as additional storage by
3136         print_reductions.
3137         (print_results): Adjust.
3138         (print_shifts, print_gotos, print_errs): New, extracted from...
3139         (print_actions): here.
3140         * src/print_graph.c (print_actions): Remove dead code.
3141
3142 2001-12-27  Akim Demaille  <akim@epita.fr>
3143
3144         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3145         `$n' and `@n'.
3146
3147 2001-12-27  Akim Demaille  <akim@epita.fr>
3148
3149         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3150         (build_relations): Adjust.
3151
3152 2001-12-27  Akim Demaille  <akim@epita.fr>
3153
3154         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3155         duplication.
3156
3157 2001-12-27  Akim Demaille  <akim@epita.fr>
3158
3159         * src/reader.c (packgram): Catch nitems overflows.
3160
3161 2001-12-27  Akim Demaille  <akim@epita.fr>
3162
3163         * src/files.c, src/files.h (guard_obstack): Remove.
3164         * src/output.c (output): Adjust.
3165         * src/reader.c (parse_braces): New, factoring...
3166         (copy_action, copy_guard): these two which are renamed as...
3167         (parse_action, parse_guard): these.
3168         As a voluntary consequence, using braces around guards is now
3169         mandatory.
3170
3171 2001-12-27  Akim Demaille  <akim@epita.fr>
3172
3173         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3174         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3175         members.
3176         (symbol_list_new): Adjust.
3177         (copy_action): action_line is the first line, not the last.
3178         (copy_guard): Just as for actions, store the `action' only, not
3179         the switch/case/break flesh.
3180         Don't parse the user action that might follow the guard, let...
3181         (readgram): do it, i.e., now, there can be an action after a
3182         guard.
3183         In other words the guard is just explicitly optional.
3184         (packgram): Adjust.
3185         * src/output.c (guards_output): New.
3186         (output_parser): Call it when needed.
3187         (output): Also free the guard and attrs obstacks.
3188         * src/files.c, src/files.h (obstack_save): Remove.
3189         (output_files): Remove.
3190         As a result, if one needs the former `.act' file, using an
3191         appropriate skeleton which requires actions and guards is now
3192         required.
3193         * src/main.c (main): Adjust.
3194         * tests/semantic.at: New.
3195         * tests/regression.at: Use `input.y' as input file name.
3196         Avoid 8+3 problems by requiring input.c when the test needs the
3197         parser.
3198
3199 2001-12-27  Akim Demaille  <akim@epita.fr>
3200
3201         * src/reader.c (symbol_list_new): Be sure to initialize all the
3202         fields.
3203
3204 2001-12-27  Akim Demaille  <akim@epita.fr>
3205
3206         All the hacks using a final pseudo state are now useless.
3207
3208         * src/LR0.c (set_state_table): state_table holds exactly nstates.
3209         * src/lalr.c (nLA): New.
3210         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3211         instead of lookaheadsp from the pseudo state (nstate + 1).
3212
3213 2001-12-27  Akim Demaille  <akim@epita.fr>
3214
3215         * src/output.c (action_row, token_actions): Use a state_t instead
3216         of a integer, and nlookaheads instead of the following state's
3217         lookaheadsp.
3218
3219 2001-12-27  Akim Demaille  <akim@epita.fr>
3220
3221         * src/conflicts.c (log_resolution, flush_shift)
3222         (resolve_sr_conflict, set_conflicts, solve_conflicts)
3223         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3224         (conflicts_print, print_reductions): Use a state_t instead of an
3225         integer when referring to a state.
3226         As much as possible, depend upon nlookaheads, instead of the
3227         `lookaheadsp' member of the following state (since lookaheads of
3228         successive states are successive, the difference between state n + 1
3229         and n served as the number of lookaheads for state n).
3230         * src/lalr.c (add_lookback_edge): Likewise.
3231         * src/print.c (print_core, print_actions, print_state)
3232         (print_results): Likewise.
3233         * src/print_graph.c (print_core, print_actions, print_state)
3234         (print_graph): Likewise.
3235         * src/conflicts.h: Adjust.
3236
3237 2001-12-27  Akim Demaille  <akim@epita.fr>
3238
3239         * src/bison.hairy: Formatting/comment changes.
3240         ANSIfy.
3241         Remove `register' indications.
3242         Add plenty of `static'.
3243
3244 2001-12-27  Akim Demaille  <akim@epita.fr>
3245
3246         * src/output.c (prepare): Drop the muscle `ntbase' which
3247         duplicates ntokens.
3248         * src/bison.simple: Formatting/comment changes.
3249         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3250         is an undocumented synonym.
3251
3252 2001-12-22  Akim Demaille  <akim@epita.fr>
3253
3254         * src/output.c (output_table_data): Change the prototype to use
3255         `int' for array ranges: some invocations do pass an int, not a
3256         short.
3257         Reported by Wayne Green.
3258
3259 2001-12-22  Akim Demaille  <akim@epita.fr>
3260
3261         Some actions of web2c.y are improperly triggered.
3262         Reported by Mike Castle.
3263
3264         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
3265         * tests/regression.at (Web2c): Rename as...
3266         (Web2c Report): this.
3267         (Web2c Actions): New.
3268
3269 2001-12-22  Akim Demaille  <akim@epita.fr>
3270
3271         Reductions in web2c.y are improperly reported.
3272         Reported by Mike Castle.
3273
3274         * src/conflicts.c (print_reductions): Fix.
3275         * tests/regression.at (Web2c): New.
3276
3277 2001-12-18  Akim Demaille  <akim@epita.fr>
3278
3279         Some host fail on `assert (!"foo")', which expands to
3280         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3281         Reported by Nelson Beebee.
3282
3283         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3284         `#define it_succeeded 0' and `assert (it_succeeded)'.
3285
3286 2001-12-17  Marc Autret  <autret_m@epita.fr>
3287
3288         * src/bison.simple: Don't hard code the skeleton line and filename.
3289         * src/output.c (output_parser): Rename 'line' as 'output_line'.
3290         New line counter 'skeleton_line' (skeleton-line muscle).
3291
3292 2001-12-17  Paul Eggert  <eggert@twinsun.com>
3293
3294         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3295         YYDEBUG must be defined to a nonzero value.
3296
3297         * src/bison.simple (yytname): Do not assume that the user defines
3298         YYDEBUG to a properly parenthesized expression.
3299
3300 2001-12-17  Akim Demaille  <akim@epita.fr>
3301
3302         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3303         nlookaheads is a new member.
3304         Adjust all users.
3305         * src/lalr.h (nlookaheads): Remove this orphan declaration.
3306         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
3307         state.

3309 2001-12-17  Akim Demaille  <akim@epita.fr>
3310
3311         * src/files.h, src/files.c (open_files, close_files): Remove.
3312         * src/main.c (main): Don't open/close files, nor invoke lex_free,
3313         let...
3314         * src/reader.c (reader): Do it.
3315
3316 2001-12-17  Akim Demaille  <akim@epita.fr>
3317
3318         * src/conflicts.c (print_reductions): Formatting changes.

3321
3322         * src/conflicts.c (flush_shift): Also adjust lookaheadset.

3325
3326 2001-12-17  Akim Demaille  <akim@epita.fr>
3327
3328         * src/output.c (output_obstack): Be static and rename as...
3329         (format_obstack): this, to avoid any confusion with files.c's
3330         output_obstack.
3331         * src/reader.h (muscle_obstack): Move to...
3332         * src/output.h: here, since it's defined in output.c.
3333
3334 2001-12-17  Akim Demaille  <akim@epita.fr>
3335
3336         * src/output.c (action_row, save_column, default_goto)
3337         (sort_actions, matching_state, pack_vector): Better variable
3338         locality.
3339
3340 2001-12-17  Akim Demaille  <akim@epita.fr>
3341

3343
3344 2001-12-17  Akim Demaille  <akim@epita.fr>
3345
3346         * src/files.c (output_files): Free the output_obstack.
3347         * src/main.c (main): Call print and print_graph conditionally.

3349         * src/print_graph.c (print_graph): Work unconditionally.
3350         * src/conflicts.c (log_resolution): Output only if verbose_flag.
3351
3352 2001-12-16  Marc Autret  <autret_m@epita.fr>
3353
3354         * src/output.c (actions_output): Fix. When we use %no-lines,
3355         there is one less line per action.
3356
3357 2001-12-16  Marc Autret  <autret_m@epita.fr>
3358
3359         * src/bison.simple: Remove a useless #line directive.
3360         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3361         * src/output.c (get_lines_number): New.
3362         (output_parser): Adjust, now takes care about the lines of a
3363         output muscles.
3364         Fix line numbering.
3365         (actions_output): Computes the number of lines taken by actions.
3366         (output_master_parser): Insert new skeleton which is the name of
3367         the output parser file name.
3368
3369 2001-12-15  Marc Autret  <autret_m@epita.fr>
3370
3371         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
3372
3373 2001-12-15  Marc Autret  <autret_m@epita.fr>
3374
3375         * src/output.c (output_gram): Keep track of the hairy one.
3376
3377 2001-12-15  Akim Demaille  <akim@epita.fr>
3378
3379         Make `make distcheck' work.
3380
3381         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3382         system.h which uses libgettext.h.
3383
3384 2001-12-15  Akim Demaille  <akim@epita.fr>
3385
3386         * src/nullable.c (set_nullable): Useless rules must be skipped,
3387         otherwise, since we range over their symbols, we might look at a
3388         nonterminal which no longer ``exists'', i.e., it is not counted in
3389         `nvars', hence we overflow our arrays.
3390
3391 2001-12-15  Akim Demaille  <akim@epita.fr>
3392
3393         The header can also be produced directly, without any obstack!
3394         Yahoo!
3395
3396         * src/files.c, src/files.h (defines_obstack): Remove.
3397         (compute_header_macro): Global.
3398         (defines_obstack_save): Remove.
3399         * src/reader.c (parse_union_decl): No longer output to
3400         defines_obstack: its content can be found in the `stype' muscle
3401         anyway.
3402         (output_token_translations): Merge into...
3403         (symbols_output): this.
3404         Rename as...
3405         (symbols_save): this.
3406         (reader): Adjust.
3407         * src/output.c (header_output): New.
3408         (output): Call it.
3409
3410 2001-12-15  Akim Demaille  <akim@epita.fr>
3411
3412         * src/reader.c (parse_union_decl): Instead of handling two obstack
3413         simultaneously, use one to define the `stype' muscle, and use the
3414         value of the latter to fill defines_obstack.
3415         (copy_comment): Remove.
3416         (copy_comment2): Work for a single obstack.
3417         Rename as...
3418         (copy_comment): this.
3419
3420 2001-12-15  Akim Demaille  <akim@epita.fr>
3421
3422         * src/lex.c, src/lex.h (xgetc): No longer static.
3423         * src/reader.c (parse_union_decl): Revamp.
3424
3425 2001-12-15  Akim Demaille  <akim@epita.fr>
3426
3427         Still making progress in separating Bison into (i) input, (ii)
3428         process, (iii) output: now we can directly output the parser file
3429         without using table_obstack at all.
3430
3431         * src/files.c, src/files.h (table_obstack): Bye bye.
3432         (parser_file_name): New.
3433         * src/files.c (compute_output_file_names): Compute it.
3434         * src/output.c (actions_output, output_parser)
3435         (output_master_parser): To a file instead of an obstack.
3436
3437 2001-12-15  Akim Demaille  <akim@epita.fr>
3438
3439         Attach actions to rules, instead of pre-outputting them to
3440         actions_obstack.
3441
3442         * src/gram.h (rule_t): action and action_line are new members.
3443         * src/reader.c (symbol_list): Likewise.
3444         (copy_action): Save the actions within the rule.
3445         (packgram): Save them in rule_table.
3446         * src/output.c (actions_output): New.
3447         (output_parser): Use it on `%%actions'.
3448         (output_rule_data): Don't free rule_table.
3449         (output): Do it.
3450         (prepare): Don't save the `action' muscle.
3451         * src/bison.simple: s/%%action/%%actions/.
3452
3453 2001-12-15  Akim Demaille  <akim@epita.fr>
3454
3455         * src/reader.c (copy_action): When --yacc, don't append a `;'
3456         to the user action: let it fail if lacking.
3457         Suggested by Arnold Robbins and Tom Tromey.
3458
3459 2001-12-14  Akim Demaille  <akim@epita.fr>
3460
3461         * src/lex.c (literalchar): Simply return the char you decoded, non
3462         longer mess around with obstacks and int pointers.
3463         Adjust all callers.
3464
3465 2001-12-14  Akim Demaille  <akim@epita.fr>
3466
3467         * src/lex.c (literalchar): Don't escape the special characters,
3468         just decode them, and keep them as char (before, eol was output as
3469         the 2 char string `\n' etc.).
3470         * src/output.c (output_rule_data): Use quotearg to output the
3471         token strings.
3472
3473 2001-12-13  Paul Eggert  <eggert@twinsun.com>
3474
3475         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3476         Do not infringe on the global user namespace when using C++.
3477         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3478         All uses of `fprintf' and `stderr' changed.
3479
3480         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3481
3482 2001-12-13  Akim Demaille  <akim@epita.fr>
3483
3484         The computation of nullable is broken: it doesn't handle empty
3485         RHS's properly.
3486
3487         * tests/torture.at (GNU AWK Grammar): New.
3488         * tests/sets.at (Nullable): New.
3489         * src/nullable.c (set_nullable): Instead of blindly looping over
3490         `ritems', loop over the rules, and then over their rhs's.
3491
3492         Work around Autotest bugs.
3493
3494         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3495         frame, because Autotest understand lines starting with a `+' as
3496         traces from the shell.  Then, they are not processed properly.
3497         Admittedly an Autotest bug, but we don't have time to wait for
3498         Autotest to catch up.
3499         * tests/regression.at (Broken Closure): Adjust to the new table
3500         frames.
3501         Move to...
3502         * tests/sets.at: here.
3503
3504 2001-12-13  Akim Demaille  <akim@epita.fr>
3505
3506         * src/closure.c (closure): Use nrules instead of playing tricks
3507         with BITS_PER_WORD.
3508
3509 2001-12-13  Akim Demaille  <akim@epita.fr>
3510
3511         * src/print.c (print_actions): Output the handling of `$' as the
3512         traces do: shifting the token EOF.  Before EOF was treated as a
3513         nonterminal.
3514         * tests/regression.at: Adjust some tests.
3515         * src/print_graph.c (print_core): Complete the set of items via
3516         closure.  The next-to-final and final states are still unsatisfying,
3517         but that's to be addressed elsewhere.
3518         No longer output the rule numbers, but do output the state number.
3519         A single loop for the shifts + gotos is enough, but picked a
3520         distinct color for each.
3521         (print_graph): Initialize and finalize closure.
3522
3523 2001-12-13  Akim Demaille  <akim@epita.fr>
3524
3525         * src/reader.c (readgram): Remove dead code, an strip useless
3526         braces.
3527         (get_type): Remove, unused.
3528
3529 2001-12-12  Akim Demaille  <akim@epita.fr>
3530
3531         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3532         on that of lib/error.c.
3533
3534 2001-12-12  Akim Demaille  <akim@epita.fr>
3535
3536         Some hosts don't like `/' in includes.
3537
3538         * src/system.h: Include libgettext.h without qualifying the path.
3539         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3540         $(top_srcdir).
3541
3542 2001-12-11  Marc Autret  <autret_m@epita.fr>
3543
3544         * src/output.c (output_parser): Remove useless muscle.
3545
3546 2001-12-11  Marc Autret  <autret_m@epita.fr>
3547
3548         * src/bison.simple: Remove #line just before %%epilogue. It
3549         is now handled in ...
3550         * src/reader.c (read_additionnal_code): Add the output of a
3551         #line for the epilogue.
3552
3553 2001-12-10  Marc Autret  <autret_m@epita.fr>
3554
3555         * src/reader.c (copy_definition): Re-use CPP-outed code which
3556         replace precedent remove.
3557         * src/bison.simple: Remove #line before %%prologue because
3558         %%input-line is wrong at this time.
3559
3560 2001-12-10  Marc Autret  <autret_m@epita.fr>
3561
3562         * src/reader.c (symbols_output): Clean up.
3563         * src/output.c (output_gram, output): Clean up.
3564
3565 2001-12-10  Akim Demaille  <akim@epita.fr>
3566
3567         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
3568         * src/LR0.c (set_state_table): here.
3569         * src/lalr.c (lalr): Call it.
3570
3571 2001-12-10  Akim Demaille  <akim@epita.fr>
3572
3573         * src/state.h (shifts): Remove the `number' member: shifts are
3574         attached to state, hence no longer need to be labelled with a
3575         state number.
3576
3577 2001-12-10  Akim Demaille  <akim@epita.fr>
3578
3579         Now that states have a complete set of members, the linked list of
3580         shifts is useless: just fill directly the state's shifts member.
3581
3582         * src/state.h (shifts): Remove the `next' member.
3583         * src/LR0.c (first_state, last_state): Remove.
3584         Adjust the callers.
3585         (augment_automaton): Don't look for the shifts that must be added
3586         a shift on EOF: it is those of the state we looked for!  But now,
3587         since shifts are attached, it is no longer needed to looking
3588         merely by its id: its number.
3589
3590 2001-12-10  Akim Demaille  <akim@epita.fr>
3591
3592         * src/LR0.c (augment_automaton): Better variable locality.
3593         Remove an impossible branch: if there is a state corresponding to
3594         the start symbol being shifted, then there is shift for the start
3595         symbol from the initial state.
3596
3597 2001-12-10  Akim Demaille  <akim@epita.fr>
3598
3599         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3600         only when appropriate: when insert_start_shifting_state' is not
3601         invoked.
3602         * tests/regression.at (Rule Line Numbers): Adjust.
3603
3604 2001-12-10  Akim Demaille  <akim@epita.fr>
3605
3606         * src/LR0.c (augment_automaton): Now that all states have shifts,
3607         merge the two cases addition shifts to the initial state.
3608
3609 2001-12-10  Akim Demaille  <akim@epita.fr>
3610
3611         * src/lalr.c (set_state_table): Move to...
3612         * src/LR0.c: here.
3613         * src/lalr.c (lalr): Don't call it...
3614         * src/LR0.c (generate_states): do it.
3615         * src/LR0.h (first_state): Remove, only the table is used.
3616
3617 2001-12-10  Akim Demaille  <akim@epita.fr>
3618
3619         * src/LR0.h (first_shift, first_reduction): Remove.
3620         * src/lalr.c: Don't use first_shift: find shifts through the
3621         states.
3622
3623 2001-12-10  Akim Demaille  <akim@epita.fr>
3624
3625         * src/LR0.c: Attach shifts to states as soon as they are
3626         computed.
3627         * src/lalr.c (set_state_table): Instead of assigning shifts to
3628         state, just assert that the mapping was properly done.
3629
3630 2001-12-10  Akim Demaille  <akim@epita.fr>
3631
3632         * src/LR0.c (insert_start_shift): Rename as...
3633         (insert_start_shifting_state): this.
3634         (insert_eof_shifting_state, insert_accepting_state): New.
3635         (augment_automaton): Adjust.
3636         Better locality of the variables.
3637         When looking if the start_symbol is shifted from the initial
3638         state, using `while (... symbol != start_symbol ...)' sounds
3639         better than `while (... symbol < start_symbol ...)': If fail
3640         to see how the order between symbols could be relevant!
3641
3642 2001-12-10  Akim Demaille  <akim@epita.fr>
3643
3644         * src/getargs.h: Don't declare `spec_name_prefix' and
3645         `spec_file_prefix', declared by src/files.h.
3646         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
3647         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
3648         * src/output.c (prepare): Adjust.
3649         * src/reader.c (symbols_output): Likewise.
3650         * src/vmsgetargs.c: Vaguely adjust, but who cares?
3651
3652 2001-12-10  Akim Demaille  <akim@epita.fr>
3653
3654         * src/muscle_tab.c (muscle_init): NULL is a better default than
3655         `"0"'.
3656
3657 2001-12-10  Akim Demaille  <akim@epita.fr>
3658
3659         * src/reader.c (reader): Calling symbols_output once is enough.
3660
3661 2001-12-10  Akim Demaille  <akim@epita.fr>
3662
3663         Now that states have a complete set of members, the linked list of
3664         reductions is useless: just fill directly the state's reductions
3665         member.
3666
3667         * src/state.h (struct reductions): Remove member `number' and
3668         `next'.
3669         * src/LR0.c (first_reduction, last_reduction): Remove.
3670         (save_reductions): Don't link the new reductions, store them in
3671         this_state.
3672         * src/lalr.c (set_state_table): No need to attach reductions to
3673         states, it's already done.
3674         * src/output.c (output_actions): No longer free the shifts, then
3675         the reductions, then the states: free all the states and their
3676         members.
3677
3678 2001-12-10  Akim Demaille  <akim@epita.fr>
3679
3680         * src/options.c (OPTN, DRTV, BOTH): New.
3681         (option_table): Use them.
3682
3683         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
3684         the job of system.h.
3685         * src/options.c: Don't include stdio.h and xalloc.h for the same
3686         reasons.
3687
3688 2001-12-10  Akim Demaille  <akim@epita.fr>
3689
3690         * src/output.c (output, prepare): Make sure the values of the
3691         muscles `action' and `prologue' are 0-terminated.
3692
3693 2001-12-10  Akim Demaille  <akim@epita.fr>
3694
3695         Clean up GCC warnings.
3696
3697         * src/reader.c (copy_action): `buf' is not used.
3698         (parse_skel_decl): Be static.
3699         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
3700         * src/options.h (create_long_option_table): Have a real prototype.
3701         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
3702         (hash_delete_at): Return const void *.
3703         Adjust casts to preserve the const.
3704
3705 2001-12-10  Akim Demaille  <akim@epita.fr>
3706
3707         * configure.in: Require 2.52g.
3708         M4 is not needed, but AUTOM4TE is.
3709         * m4/m4.m4: Remove.
3710         * tests/Makefile.am: Adjust.
3711
3712 2001-12-10  Akim Demaille  <akim@epita.fr>
3713
3714         One structure for states is enough, even though theoretically
3715         there are LR(0) states and LALR(1) states.
3716
3717         * src/lalr.h (state_t): Remove.
3718         (state_table): Be state_t **, not state_t *.
3719         * src/state.h (core, CORE_ALLOC): Rename as...
3720         (state_t, STATE_ALLOC): this.
3721         Add the LALR(1) members: shifts, reductions, errs.
3722         * src/LR0.c (state_table): Rename as...
3723         (state_hash): this, to avoid name clashes with the global
3724         `state_table'.
3725         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
3726         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
3727
3728 2001-12-10  Akim Demaille  <akim@epita.fr>
3729
3730         Bison dumps core on bash.y.
3731         Reported by Pascal Bart.
3732
3733         * src/warshall.c (bitmatrix_print): New.
3734         (TC): Use it.
3735         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
3736         j must be the outer loop.
3737         * tests/regression.at (Broken Closure): New.
3738
3739 2001-12-05  Akim Demaille  <akim@epita.fr>
3740
3741         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
3742         its argument.
3743         Reported by Peter Hámorský.
3744
3745 2001-12-05  Akim Demaille  <akim@epita.fr>
3746
3747         * src/conflicts.c (err_table): Remove.
3748         (resolve_sr_conflict): Adjust.
3749         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
3750         Rename as...
3751         (state_t.reductions, state_t.shifts): this.
3752
3753 2001-12-05  Akim Demaille  <akim@epita.fr>
3754
3755         * src/reduce.c (reduce_grammar_tables): No longer disable the
3756         removal of useless rules via CPP but via `if (0)', so that the
3757         compiler still check the code is valid.
3758         For instance, it should have noticed `rline' no longer exists: use
3759         the `line' member of rule_t.
3760         * src/gram.c (dummy, rline): Remove, unused.
3761
3762 2001-12-05  Akim Demaille  <akim@epita.fr>
3763
3764         * src/output.c (pack_vector): Use assert, not berror.
3765         * src/main.c (berror): Remove, unused.
3766
3767 2001-12-05  Akim Demaille  <akim@epita.fr>
3768
3769         New experimental feature: if --verbose --trace output all the
3770         items of a state, not only its kernel.
3771
3772         * src/print.c (print_core): If `trace_flag', then invoke closure
3773         before outputting the items of the state (print_core is no longer
3774         a correct name them).
3775         (print_results): Invoke new_closure/free_closure if needed.
3776
3777 2001-12-05  Akim Demaille  <akim@epita.fr>
3778
3779         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
3780         * src/closure.c, src/closure.h (itemsetsize): Rename as...
3781         (nitemset): for consistency with the rest of the project.
3782
3783 2001-12-05  Akim Demaille  <akim@epita.fr>
3784
3785         * src/closure.c (print_closure): Improve.
3786         (closure): Use it for printing input and output.
3787
3788 2001-12-05  Akim Demaille  <akim@epita.fr>
3789
3790         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
3791         indexed by nonterminals.
3792
3793 2001-12-05  Akim Demaille  <akim@epita.fr>
3794
3795         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
3796         what it was!).
3797         * src/warshall.h: Remove accidental duplication of the content.
3798
3799 2001-12-05  Akim Demaille  <akim@epita.fr>
3800
3801         * src/closure.c (set_fderives): De-obfuscate.

3810
3811 2001-12-05  Akim Demaille  <akim@epita.fr>
3812
3813         * src/output.c (action_row): De-obfuscate
3814         using the good o' techniques: arrays not pointers, variable
3815         locality, BITISSET, RESETBIT etc.
3816
3817 2001-12-05  Akim Demaille  <akim@epita.fr>
3818
3819         Pessimize the code to simplify it: from now on, all the states
3820         have a valid SHIFTS, which NSHIFTS is possibly 0.
3821
3822         * src/LR0.c (shifts_new): Be global and move to..
3823         * src/state.c, src/state.h: here.
3824         * src/conflicts, src/lalr.c, src/output.c, src/print.c,

3826
3827 2001-12-05  Akim Demaille  <akim@epita.fr>
3828
3829         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
3830         * src/conflicts.c: Use it.
3831         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
3832         incorrectly ``simplified''.
3833
3834 2001-12-05  Akim Demaille  <akim@epita.fr>
3835
3836         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

3838         locality, BITISSET, RESETBIT etc.
3839
3840 2001-12-05  Akim Demaille  <akim@epita.fr>
3841
3842         * src/state.h (SHIFT_SYMBOL): New.
3843         * src/conflicts.c: Use it to deobfuscate.
3844
3845 2001-12-05  Akim Demaille  <akim@epita.fr>
3846
3847         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
3848         (print_reductions): De-obfuscate using the good o' techniques:
3849         arrays not pointers, variable locality, BITISSET.
3850
3851 2001-12-05  Akim Demaille  <akim@epita.fr>
3852
3853         * src/conflicts.c (print_reductions): Arrays, not pointers.
3854         Use BITISSET.
3855
3856 2001-12-05  Akim Demaille  <akim@epita.fr>
3857
3858         * src/conflicts.c (print_reductions): Pessimize, but clarify.

3876
3877 2001-12-05  Akim Demaille  <akim@epita.fr>
3878
3879         * src/LR0.c (augment_automaton): Formatting changes.
3880         Better variable locality.
3881
3882 2001-12-05  Akim Demaille  <akim@epita.fr>
3883
3884         * src/lalr.c (matrix_print): New.
3885         (transpose): Use it.
3886         Use arrays instead of pointers.
3887
3888 2001-12-05  Akim Demaille  <akim@epita.fr>
3889
3890         * src/lalr.c (maxrhs): Move to...
3891         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
3892         * src/lalr.c (build_relations): Adjust.
3893
3894 2001-12-05  Akim Demaille  <akim@epita.fr>
3895
3896         * src/lalr.c (transpose): Free the memory allocated to the
3897         argument, as it is replaced by the results by the unique caller.
3898         (build_relations): Merely invoke transpose: it handles the memory
3899         deallocation.
3900         Improve variable locality.
3901         Avoid variables used as mere abbreviations.
3902         (compute_lookaheads): Use arrays instead of pointers.
3903
3904 2001-12-05  Akim Demaille  <akim@epita.fr>
3905
3906         * src/lalr.c (initialize_F): Improve variable locality.

3910
3911         * src/derives.c (print_derives): Display the ruleno.
3912         * src/lalr.c (initialize_F, transpose): Better variable locality
3913         to improve readability.
3914         Avoid variables used as mere abbreviations.
3915
3916 2001-12-05  Akim Demaille  <akim@epita.fr>
3917

3920 2001-12-05  Akim Demaille  <akim@epita.fr>
3921
3922         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
3923         the handling of squeue.
3924         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3925
3926 2001-12-05  Akim Demaille  <akim@epita.fr>
3927
3928         Because useless nonterminals are now kept alive (instead of being
3929         `destroyed'), we now sometimes examine them, and store information
3930         related to them.  Hence we need to know their number, and adjust
3931         memory allocations.
3932
3933         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3934         static.
3935         * src/LR0.c (allocate_itemsets): The memory allocated to
3936         `symbol_count' was used for two different purpose: once to count
3937         the number of occurrences of each symbol, and later reassigned to
3938         `shift_symbol', containing the symbol that can be shifted from a
3939         given state.
3940         Deobfuscate, i.e., allocate, use and free `symbol_count' here
3941         only, and...
3942         (new_itemsets): Allocate `shift_symbol' here.
3943         (allocate_itemsets): symbol_count includes useless nonterminals.
3944         Make room for them.
3945         (free_storage): Use `free', not `XFREE', for pointers that cannot
3946         be null.
3947
3948 2001-12-05  Akim Demaille  <akim@epita.fr>
3949
3950         * src/nullable.c (set_nullable): Deobfuscate the handling of
3951         ritem.
3952         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3953
3954 2001-12-05  Akim Demaille  <akim@epita.fr>
3955
3956         * src/gram.c, src/gram.h (ritem_print): New.
3957         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
3958         (This useless function was defined only to work around VMS linkers
3959         that can't handle compilation units with variables only).
3960         * src/reduce.c (dump_grammar): Use it to trace the construction of
3961         ritem.
3962
3963 2001-12-04  Paul Eggert  <eggert@twinsun.com>
3964
3965         * src/bison.simple (union yyalloc): Change member names
3966         to be the same as the stack names.
3967         (yyparse): yyptr is now union yyalloc *, not char *.
3968         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
3969         and may generate better code on some machines.
3970         (yystpcpy): Use prototype if __STDC__ is defined, not just
3971         if __cplusplus is defined.
3972
3973 2001-11-30  Akim Demaille  <akim@epita.fr>
3974
3975         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
3976         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
3977         Gettext doesn't compile cleanly, and dies with -Werror.
3978         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
3979         Include WARNING_CFLAGS here.
3980         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
3981         before being defined.
3982
3983 2001-11-27  Paul Eggert  <eggert@twinsun.com>
3984
3985         * lib/quotearg.h (quotearg_n, quotearg_n_style):
3986         First arg is int, not unsigned.
3987         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
3988         (SIZE_MAX, UINT_MAX): New macros.
3989         (quotearg_n_options): Abort if N is negative.
3990         Avoid overflow check on hosts where size_t is 64 bits and int
3991         is 32 bits, as overflow is impossible there.
3992         Fix off-by-one typo that caused unnecessary reallocation.
3993
3994 2001-11-29  Paul Eggert  <eggert@twinsun.com>
3995
3996         Name space cleanup in generated parser.
3997
3998         * doc/bison.texinfo (Bison Parser): Discuss system headers
3999         and their effect on the user name space.
4000
4001         * src/bison.simple:
4002         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4003         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4004         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4005
4006         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4007         on user names when possible.
4008
4009         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4010         Simplify test for whather <alloca.h> exists.
4011
4012         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4013
4014         (<stdio.h>): Include if YYDEBUG.
4015
4016         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4017         ! defined (yyoverflow) && ! defined (yymemcpy).
4018
4019         (yymemcpy, yyparse): Rename local variables as needed so that
4020         they all begin with 'yy'.
4021
4022         (yystrlen, yystpcpy): New functions.
4023
4024         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4025         All uses changed.
4026
4027         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4028         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4029         and YYSTACK_FREE instead of malloc and free.
4030
4031 2001-11-30  Akim Demaille  <akim@epita.fr>
4032
4033         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4034         before their first uses.
4035         (YYBISON, YYPURE): Move to the top of the output.

4040
4041 2001-11-30  Akim Demaille  <akim@epita.fr>
4042
4043         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4044         if body instead of `;' to pacify GCC's warnings.
4045
4046 2001-11-30  Akim Demaille  <akim@epita.fr>
4047
4048         Instead of mapping the LHS of unused rules to -1, keep the LHS
4049         valid, but flag the rules as invalid.
4050
4051         * src/gram.h (rule_t): `useful' is a new member.
4052         * src/print.c (print_grammar): Adjust.
4053         * src/derives.c (set_derives): Likewise.

4055         * src/reduce.c (reduce_grammar_tables): Likewise.
4056         * tests/reduce.at (Underivable Rules, Useless Rules): New.

4064
4065 2001-11-30  Akim Demaille  <akim@epita.fr>
4066
4067         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4068         useless nonterminals, move them at the end of the symbol arrays.
4069         (reduce_output): Adjust.
4070         * tests/reduce.at (Useless Nonterminals): Adjust.
4071
4072 2001-11-30  Akim Demaille  <akim@epita.fr>

4075         (nonterminals_reduce): New, extracted from...
4076         (reduce_grammar_tables): here.
4077         (reduce_grammar): Call nonterminals_reduce.
4078
4079 2001-11-29  Paul Eggert  <eggert@twinsun.com>

4082         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4083         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4084         New macros.
4085         (union yyalloc): New type.
4086         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4087         an arbitrary restriction on hosts where size_t is wider than int.
4088
4089         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4090         a parser stack overflow.  Allocate just one block of memory for all
4091         three stacks, instead of allocating three blocks; this typically is
4092         faster and reduces fragmentation.
4093
4094         Do not limit the number of items in the stack to a value that fits
4095         in 'int', as this is an arbitrary limit on hosts with 64-bit
4096         size_t and 32-bit int.
4097
4098 2001-11-29  Marc Autret  <autret_m@epita.fr>
4099
4100         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

4104 2001-11-28  Marc Autret  <autret_m@epita.fr>

4115         (prepare): Echo name modification.
4116         * src/getargs.h: Clean its extern declaration.
4117         * src/getargs.c (error_verbose_flag): Remove.
4118         (getargs): Remove case 'e'.
4119         * src/options.c (option_table): 'error-verbose' is now seen as simple
4120         percent option.
4121         Include output.h.
4122
4123         * src/reader.c (read_declarations): Remove case tok_include.
4124         (parse_include_decl): Remove.

4126         * src/options.c (option_table): 'include' is now a simple command line
4127         option.
4128
4129 2001-11-28  Marc Autret  <autret_m@epita.fr>
4130
4131         * src/bison.simple: Adjust muscle names.
4132         * src/muscle_tab.c (muscle_init): Also rename the muscles.

4134         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
4135
4136 2001-11-28  Marc Autret  <autret_m@epita.fr>

4145
4146 2001-11-28  Akim Demaille  <akim@epita.fr>
4147
4148         * src/closure.c (closure): `b' and `ruleno' denote the same value:
4149         keep ruleno only.
4150
4151 2001-11-28  Akim Demaille  <akim@epita.fr>
4152
4153         * src/closure.c (closure): Instead of looping over word in array
4154         then bits in words, loop over bits in array.
4155
4156 2001-11-28  Akim Demaille  <akim@epita.fr>
4157
4158         * src/closure.c (closure): No longer optimize the special case
4159         where all the bits of `ruleset[r]' are set to 0, to make the code
4160         clearer.
4161
4162 2001-11-28  Akim Demaille  <akim@epita.fr>
4163
4164         * src/closure.c (closure): `r' and `c' are new variables, used to
4165         de-obfuscate accesses to RULESET and CORE.

4178         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
4179         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
4180         as all tags are free'ed afterwards.
4181         From Enrico Scholz.
4182
4183 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4184
4185         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
4186         use alloca when we didn't want to, and vice versa.
4187
4188 2001-11-27  Marc Autret  <autret_m@epita.fr>

5563         with something new. Skeletons are now processed character by character

5912         import in Bison features implemented in 2.49c since 2.13.

5949         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
5950         `%debug'.
5951         Handle the actions for `%semantic_parser' and `%pure_parser' here,
5952         instead of returning a token.

5954         * src/reader.c (read_declarations): Adjust.

5978         * src/files.c (open_files): Fix the computation of short_base_name

5986
5987 2000-12-20  Akim Demaille  <akim@epita.fr>
5988
5989         * src/files.c (open_files): Actually the `.output' file is based

6020         (base_names): Eve out from open_files.
6021         Try to simplify the rather hairy computation of base_name and
6022         short_base_name.
6023         (open_files): Use it.
6024         * tests/suite.at (Checking output file names): New test.

6063
6064         * src/files.c (open_files): Yipee!  We no longer need all the code
6065         looking for `/tmp' since we have no tmp file.
6066

6096         * lib/obstack.h: Formatting changes.
6097         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6098         prevents type checking.
6099         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6100         cast the value to (void *): assigning a `foo *' to a `void *'
6101         variable is valid.
6102         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
6103         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6119
6120         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
6121         macros.

6138
6139 2000-11-07  Akim Demaille  <akim@epita.fr>
6140
6141         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

6166

6182         Use `obstack_save'.
6183         * src/main.c (main): Don't use `atexit' to register `done', since
6184         it no longer has to remove tmp files, just call `output_files'
6185         when there are no errors.
6186
6187 2000-11-02  Akim Demaille  <akim@epita.fr>

6290         When a literal string is used to define two different tokens,
6291         `bison -v' segfaults.
6292         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6293
6294         * tests/regression.m4: New file.
6295         Include the core of the sample provided by Piotr Gackiewicz.

6303         From Neil Booth.

6305 2000-10-02  Paul Eggert  <eggert@twinsun.com>
6306
6307         * bison.s1 (yyparse): Assign the default value
6308         unconditionally, to avoid a GCC warning and make the parser a
6309         tad smaller.
6310
6311 2000-10-02  Akim Demaille  <akim@epita.fr>
6312

6322
6323         The location tracking mechanism is precious for parse error
6324         messages.  Nevertheless, it is enabled only when `@n' is used in
6325         the grammar, which is a different issue (you can use it in error
6326         message, but not in the grammar per se).  Therefore, there should
6327         be another means to enable it.
6328
6329         * src/getargs.c (getargs): Support `--locations'.
6330         (usage): Report it.

6332         * src/lex.c (percent_table): Support `%locations'.

6334         with `locationsflag'.
6335         * doc/bison.texinfo: Document `--locations' and `%locations'.
6336         Sort the options.
6337         * tests/calc.m4: Test it.
6338
6339         For regularity of the names, replace each
6340         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6341         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6342         In addition replace each `flag' with `_flag'.
6343
6344 2000-10-02  Akim Demaille  <akim@epita.fr>
6345
6346         Also test parse error messages, including with YYERROR_VERBOSE.
6347
6348         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6349         associative).
6350         Use it to check the computations.
6351         Use it to check `nonassoc' is honored.
6352         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6353         `--yyerror-verbose'.
6354         (_AT_CHECK_CALC): Adjust to this option.
6355         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6356
6357 2000-10-02  Akim Demaille  <akim@epita.fr>
6358
6359         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
6360         the latter demonstrates a flaw in the handling of non debugging
6361         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6362         was used in order to simplify:
6363
6364         #if YYDEBUG
6365         if (yydebug)
6366         {
6367         ...
6368         }
6369         #endif
6370
6371         into
6372
6373         if (yydebug)
6374         {
6375         ...
6376         }
6377
6378         unfortunately this leads to a CPP conflict when
6379         `--name-prefix=foo' is used since it produces `#define yydebug
6380         foodebug'.
6381
6382         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6383         (YYDPRINTF): New macro.
6384         Spread its use.
6385         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6386         the bison options.
6387         Also test `--verbose', `--defines' and `--name-prefix'.
6388
6389 2000-10-02  Akim Demaille  <akim@epita.fr>
6390
6391         Improve the readability of the produced parsers.
6392
6393         * src/bison.s1: Formatting changes.
6394         Improve the comment related to the `$' mark.
6395         (yydefault): Don't fall through to `yyresume': `goto' there.
6396         * src/output.c (output_parser): When the `$' is met, skip the end
6397         of its line.
6398         New variable, `number_of_dollar_signs', to check there's exactly
6399         one `$' in the parser skeleton.
6400
6401 2000-10-02  Akim Demaille  <akim@epita.fr>
6402
6403         * lib/xstrdup.c: New file, from the fileutils.
6404         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6405         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6406         instead of strlen + xmalloc + strcpy.
6407         * src/symtab.c (copys): Remove, use xstrdup instead.
6408
6409 2000-10-02  Akim Demaille  <akim@epita.fr>
6410
6411         * src/gram.h (associativity): New enum type which replaces the
6412         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6413         `right_assoc', `left_assoc' and `non_assoc'.
6414         Adjust all dependencies.
6415         * src/reader.c: Formatting changes.
6416         (LTYPESTR): Don't define it, use it as a literal in
6417         `reader_output_yylsp'.
6418         * src/symtab.h (symbol_class): New enum type which replaces the
6419         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
6420         `sunknown', `stoken and `snterm'.
6421
6422 2000-10-02  Akim Demaille  <akim@epita.fr>
6423
6424         * src/getargs.c (fixed_outfiles): Rename as...

6426         Adjust dependencies.
6427
6428 2000-10-02  Akim Demaille  <akim@epita.fr>
6429
6430         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6431         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
6432         difficult and introduced a lot of core dump.  It turns out that
6433         Bison used an implementation of `xmalloc' based on `calloc', and
6434         at various places it does depend upon the initialization to 0.  I
6435         have not tried to isolate the pertinent places, and all the former
6436         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
6437         someone should address this issue.
6438
6439         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
6440         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
6441         files.
6442         Adjust dependencies.
6443         * src/warshall.h: New file.
6444         Propagate.

6446 2000-10-02  Akim Demaille  <akim@epita.fr>

6448         Various anti-`extern in *.c' changes.

6451
6452 2000-10-02  Akim Demaille  <akim@epita.fr>
6453
6454         * src/state.h (nstates, final_state, first_state, first_shift)

6456         * src/LR0.h: to here.

6533
6534         * src/output.c (token_actions): Introduce a temporary array,
6535         YYDEFACT, that makes it possible for this function to use

6537
6538 2000-10-02  Akim Demaille  <akim@epita.fr>
6539
6540         `user_toknums' is output as a `short[]' in `output.c', while it is
6541         defined as a `int[]' in `reader.c'.  For consistency with the
6542         other output tables, `user_toknums' is now defined as a table of
6543         shorts.
6544
6545         * src/reader.c (user_toknums): Be a short table instead of an int
6546         table.

6558         order to get rid of the `static' prototypes.
6559         No longer use `register'.
6560         * src/output.h: New file.
6561         Propagate its inclusion in files explicitly prototyping functions
6562         from output.c.

6584         inclusion.
6585         Don't define PARAMS.
6586         * src/system.h: Define PARAMS.
6587         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
6588         purpose of config.h.  system.h must not try to fix wrong
6589         definitions in config.h.

6749
6750         * src/Makefile.am (bison.simple): Fix the awk program: quote only
6751         the file name, not the whole `#line LINE FILE'.
6752
6753 2000-03-17  Akim Demaille  <akim@epita.fr>
6754
6755         On syntax errors, report the token on which we choked.
6756
6757         * src/bison.s1 (yyparse): In the label yyerrlab, when

6775

6777         copy_comment.  Removed now unused `match', `ended',
6778         `cplus_comment'.
6779         (copy_comment, copy_string): Moved, to be visible from
6780         copy_definition.
6781
6782 2000-03-17  Akim Demaille  <akim@epita.fr>
6783
6784         * src/reader.c (copy_string): Declare `static inline'.  No

6804
6805 2000-03-17  Akim Demaille  <akim@epita.fr>
6806
6807         Change the handling of @s so that they behave exactly like $s.
6808         There is now a pseudo variable @$ (readble and writable), location
6809         of the lhs of the rule (by default ranging from the location of
6810         the first symbol of the rhs, to the location of the last symbol,
6811         or, if the rhs is empty, YYLLOC).
6812
6813         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
6814         yyval.
6815         (yyparse): When providing a default semantic action, provide a
6816         default location action.
6817         (after the $): No longer change `*YYLSP', just stack YYLOC the
6818         same way you stack YYVAL.
6819         * src/reader.c (read_declarations): Use warns.
6820         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
6821         (copy_action, case '@'): Likewise.
6822         Use a standard error message, to save useless work from
6823         translators.
6824
6825 2000-03-17  Akim Demaille  <akim@epita.fr>
6826
6827         * src/bison.s1: Formatting and cosmetics changes.
6828         * src/reader.c: Likewise.
6829         Update the Copyright notice.
6830
6831 2000-03-17  Akim Demaille  <akim@epita.fr>
6832
6833         * src/bison.s1 (#line): All set to `#line' only, since the
6834         Makefile now handles them.
6835
6836 2000-03-16  Akim Demaille  <akim@epita.fr>
6837

6839         some of the tables.

6844
6845         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
6846         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
6847         One `#if YYDEBUG' remains, since it uses variables which are
6848         defined only if `YYDEBUG != 0'.
6849
6850 2000-03-16  Akim Demaille  <akim@epita.fr>
6851
6852         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
6853         and related variables so that the similarities are highlighted.

6862
6863 2000-03-16  Akim Demaille  <akim@epita.fr>
6864

6873         * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
6874         handled via src/Makefile.am.
6875         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
6876         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
6877         autoheader.

6882         the proper line number and file name.
6883         (DEFS): Propagate the location of bison library files and of the
6884         locale files.
6885         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
6886         builddir.
6887         * acinclude.m4: Remove, replaced by the directory m4.
6888         * m4/Makefile.am (EXTRA_DIST): New variable.
6889         * m4/gettext.m4: New file, from the fileutils.

7555         (fatals): Updated to not use VARARGS1.
7556         (printable_version, int_to_string, warn, warni, warns, warnss)
7557         (warnsss): New error reporting functions.  Avoid abort for error.

7575         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
7576         major changes to files.c.
7577         (lex) Retain in the incoming stream a character following
7578         an incorrect '/'.
7579         (skip_white_space, lex):  Revised most error messages
7580         and changed fatal to warn to avoid aborting.
