   3         * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
   4         (yyparse): here.  This undoes some of the 2002-07-25 change.
   5         Compatibility problem reported by Ralf S. Engelschall with
   6         OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

  20
  21         Portability fixes for bitsets; this also avoids several GCC
  22         warnings.
  23
  24         * lib/abitset.c: Include <stddef.h>, for offsetof.
  25         * lib/lbitset.c: Likewise.
  26
  27         * lib/abitset.c (abitset_bytes): Return a size that is aligned
  28         properly for vectors of objects.  Do not assume that adding a
  29         header size to a multiple of a word size yields a value that is
  30         properly aligned for the whole union.
  31         * lib/bitsetv.c (bitsetv_alloc): Likewise.
  32
  33         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
  34         unique names for structures.
  35         * lib/ebitset.c (ebitset_bytes): Likewise.
  36         * lib/lbitset.c (lbitset_bytes): Likewise.
  37
  38         * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
  39         abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
  40         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
  41         abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
  42         abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
  43         abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
  44         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
  45         to improve the type-checking that GCC can do.
  46         * lib/bitset.c (bitset_op4_cmp): Likewise.
  47         * lib/bitset_stats.c (bitset_stats_count,
  48         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
  49         bitset_stats_copy, bitset_stats_disjoint_p,
  50         bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
  51         bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
  52         bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
  53         bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
  54         bitset_stats_and_or_cmp, bitset_stats_andn_or,
  55         bitset_stats_andn_or_cmp, bitset_stats_or_and,
  56         bitset_stats_or_and_cmp): Likewise.
  57         * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
  58         lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
  59         lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
  60         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
  61
  62         * lib/abitset.h: Include bitset.h, not bbitset.h.
  63         * lib/ebitset.h: Likewise.
  64         * lib/lbitset.h: Likewise.
  65
  66         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
  67         All instances of parameters of type enum bitset_opts are now of
  68         type enum_bitset_opts, to conform to the C Standard, and similarly
  69         for enum_bitset_type.
  70         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
  71         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
  72
  73         Do not use "struct bitset_struct" to mean different things in
  74         different modules.  Not only is this confusing, it violates
  75         the C Standard, which requires that structure types in different
  76         modules must be compatible if one is to be passed to the other.
  77         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
  78         All instances of "struct bitset_struct *" replaced with "bitset".
  79         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
  80         (union bitset_union, struct abitset_struct, struct ebitset_struct,
  81         struct lbitset_struct, struct bitset_stats_struct): New types.
  82         All uses of struct bitset_struct changed to union bitset_union,
  83         etc.
  84         * lib/abitset.c (struct abitset_struct, abitset,
  85         struct bitset_struct): Remove.
  86         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
  87         struct bitset_struct): Remove.
  88         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
  89         bitset_struct): Remove.
  90         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
  91         Likewise.
  92
  93         Do not call a function of type T using a call that assumes the
  94         function is of a different type U.  Standard C requires that a
  95         function must be called with a type that is compatible with its
  96         definition.
  97         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
  98         New decls.
  99         * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 100         New functions.
 101         * lib/ebitset.c (PFV): Remove.
 102         * lib/lbitset.c (PFV): Likewise.
 103         * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
 104         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
 105         decls.
 106         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
 107         (ebitset_vtable): Use them.
 108         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
 109         lbitset_xor): New functions.
 110         (lbitset_vtable): Use them.
 111
 112         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
 113         Declare.
 114
 115         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
 116         GCC warning.
 117         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
 118         Use offsetof, for simplicity.
 119
 120 2002-10-06  Paul Eggert  <eggert@twinsun.com>
 121
 122         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
 123         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
 124         <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
 125         which was inadvertently undone by the 2002-09-30 patch.
 126         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
 127         the same width as int.
 128
 129 2002-10-04  Paul Eggert  <eggert@twinsun.com>
 130
 131         Version 1.50.
 132
 133         * configure.ac (AC_INIT), NEWS: Increment version number.
 134
 135         * doc/bison.texinfo: Minor spelling, grammar, and white space
 136         fixes.
 137         (Symbols): Mention that any negative value returned from yylex
 138         signifies end-of-input.  Warn about negative chars.  Mention
 139         the portable Standard C character set.
 140
 141         The GNU coding standard says CFLAGS and YFLAGS are reserved
 142         for the installer to set.
 143         * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
 144         * src/Makefile.am (AM_CFLAGS): Likewise.
 145         (AM_YFLAGS): Renamed from YFLAGS.
 146
 147         Fix some MAX and MIN problems.
 148         * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
 149         * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
 150         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
 151         * src/reader.c (reader): Use it.
 152
 153         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
 154         POSIX 1003.1-2001 has removed fgrep.
 155
 156 2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
 157
 158         * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
 159         interpreted as signed.
 160         * lib/ebitset.c (ebitset_list): Fix bug.
 161
 162 2002-10-01  Paul Eggert  <eggert@twinsun.com>
 163
 164         More fixes for 64-bit hosts and large bitsets.
 165
 166         * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
 167         abitset_size, abitset_list, abitset_list_reverse, abitset_list):
 168         Use bitset_bindex, not int or unsigned int or size_t, to count bits.

 170         struct bitset_vtable.list, struct bitset_vtable.list_reverse,

 172         bitset_count_): Likewise.
 173         * lib/bitset.h (bitset_iterator.num, bitset_iterator.i,
 174         bitset_first, bitset_last): Likewise.
 175         * lib/bitset_stats.c (bitset_stats_size, bitset_stats_list,
 176         bitset_stats_list_reverse, bitset_stats_size,
 177         bitset_stats_count, bitset_stats_list, bitset_stat_list_reverse):
 178         Likewise.
 179         * lib/bitsetv-print.c (bitsetv_matrix_dump): Likewise.
 180         * lib/bitsetv.c (bitsetv_alloc, bitsetv_create, bitsetv_free,
 181         bitsetv_zero, bitsetv_ones, bitsetv_transitive_closure,

 202
 203         * lib/abitset.c (abitset_empty_p, abitset_not, abitset_equal_p,
 204         abitset_subset_p, abitset_disjoint_p, abitset_and,
 205         abitset_and_cmp, abitset_andn, abitset_andn_cmp, abitset_or,

 225         * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
 226         BITSET_SIZE_MAX): New macros.
 227         (BITSET_INDEX_MAX): Remove.  It wasn't right, since it assumed that
 228         sizeof (bitset_word) == sizeof (bitset_windex).  All uses changed
 229         to BITSET_WINDEX_MAX.
 230
 231         * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
 232         bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

 238
 239         * lib/lbitset.c (lbitset_elt_find): Simplify windex calculation
 240         and avoid cast to unsigned.

 251         invocations.

 332
 333         * doc/bison.texinfo (Conditions): Make explicit that the GPL
 334         exception applies only to yacc.c.  This is a modification of a
 335         patch originally suggested by Akim Demaille.

 341         * data/yacc.c: here.
 342
 343         * data/lalr1.cc (struct yyltype): Don't define it, since we use
 344         LocationType.
 345         (b4_ltype): Default to yy::Location from location.hh.
 346
 347 2002-09-04  Jim Meyering  <jim@meyering.net>
 348
 349         * data/yacc.c: Guard the declaration of yytoknum also with
 350         `#ifdef YYPRINT', so it is declared only when used.
 351
 352 2002-09-04  Akim Demaille  <akim@epita.fr>
 353
 354         * configure.in: Rename as...

 369         (DISTCLEANFILES): Remove.
 370         * NEWS: Mention that GNU M4 is now required.  Clarify what is

 382         (yyreportParseError): Use size_t for yysize.
 383         (yy_yypstack): No longer nested inside yypstates, as nested
 384         functions are not portable.  Do not assume size_t is the
 385         same width as int.
 386         (yypstates): Do not assume that ptrdiff_t is the same width
 387         as int, and similarly for yyposn and YYINDEX.
 388
 389         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 390
 391         * lib/Makefile.am (INCLUDES): Do not include from the intl
 392         directory, which has been removed.
 393         * src/Makefile.am (INCLUDES): Likewise.

 401
 402         * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):

 408         * lib/bitset.h (bitset_set, bitset_reset): Likewise.

 414         portability to one's complement hosts!).
 415         * lib/ebitset.c (ebitset_op1): Likewise.
 416         * lib/lbitset.c (lbitset_op1): Likewise.
 417

 423         lib/gettext.h: Sync with diffutils.
 424

 427
 428         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 429         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 430         check for void *.
 431
 432         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 433         size_t; the old version tried to do this but casted improperly.
 434         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 435         (bitset_test): Now returns int, not unsigned long.

 439         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 440         name locals "index", as it generates unnecessary warnings on some
 441         hosts that have an "index" function.
 442
 443         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 444         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
 445         they need translation.

 459         * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.

 461         * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
 462
 463         * po/LINGUAS: Add pt_BR.

 465         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 466         lib/timevar.c.
 467         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 468         manual recommends.
 469         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 470
 471         * src/complain.c (strerror_r): Remove decl; not needed.
 472         (strerror): Use same pattern as ../lib/error.c.
 473
 474         * src/files.c, src/files.h (compute_header_macro): Remove; unused.

 477
 478         * src/main.c (main): Cast result of bindtextdomain and textdomain
 479         to void, to avoid a GCC warning when --disable-nls is in effect.
 480
 481         * src/scan-gram.l: Use strings rather than escapes when possible,
 482         to minimize the number of warnings from xgettext.
 483         (handle_action_dollar, handle_action_at): Don't use isdigit,
 484         as it mishandles negative chars and it may not work as expected
 485         outside the C locale.
 486
 487         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 488         this is a GCC extension and is not portable to other compilers.
 489
 490         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 491         Do not include <ctype.h>; no longer needed.
 492         Do not include <malloc.h>; no longer needed (and generates
 493         warnings on OpenBSD 3.0).
 494
 495         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
 496         it's not portable.
 497
 498         * tests/regression.at: Do not use 'cc -c input.c -o input';
 499         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
 500
 501         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
 502         exit status as failure, not just exit status 1.  Sun C exits
 503         with status 2 sometimes.
 504
 505         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
 506         Use it for the two large tests.
 507
 508 2002-08-02  Akim Demaille  <akim@epita.fr>
 509
 510         * src/conflicts.c (conflicts_output): Don't output rules never
 511         reduced here, since anyway that computation doesn't work.
 512         * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
 513         (rule_useless_p, rule_never_reduced_p): New.

 519         reduced to...
 520         (token_actions): here.
 521         * src/main.c (main): Make the parser before making the report, so
 522         that rules never reduced are computed.
 523         Call grammar_rules_never_reduced_report.
 524         * src/print.c (print_results): Report rules never reduced.
 525         * tests/conflicts.at, tests/reduce.at: Adjust.
 526
 527 2002-08-01  Akim Demaille  <akim@epita.fr>
 528
 529         Instead of attaching lookaheads and duplicating the rules being
 530         reduced by a state, attach the lookaheads to the reductions.
 531
 532         * src/state.h (state_t): Remove the `lookaheads',
 533         `lookaheads_rule' member.
 534         (reductions_t): Add a `lookaheads' member.

 536         * src/state.c (reductions_new): Initialize the lookaheads member
 537         to 0.
 538         (state_rule_lookaheads_print): Adjust.
 539         * src/state.h, src/state.c (state_reductions_find): New.

 546         (initialize_LA): this.
 547         (lalr_free): Adjust.
 548         * src/main.c (main): Don't free nullable and derives too early: it
 549         is used by --verbose.
 550         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
 551
 552 2002-08-01  Akim Demaille  <akim@epita.fr>
 553
 554         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
 555         `rule_number_t**'.
 556         (set_derives, free_derives): Rename as...

 563         pointers, instead of their numbers.
 564         * src/main.c (main): Call nullable_free, and derives_free earlier,
 565         as they were lo longer used.
 566
 567 2002-08-01  Akim Demaille  <akim@epita.fr>
 568
 569         * lib/timevar.c (get_time): Include children time.
 570         * src/lalr.h (LA, LArule): Don't export them: used with the
 571         state_t.
 572         * src/lalr.c (LA, LArule): Static.

 575         * src/tables.c (pack_vector): Check whether loc is >= to the
 576         table_size, not >.
 577         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
 578         (tables_generate): do it, since that's also it which allocates
 579         them.
 580         Don't free LA and LArule, main does.
 581
 582 2002-07-31  Akim Demaille  <akim@epita.fr>
 583

 656         Normalize conflict related messages.

 660         (conflict_report_yacc): New, extracted from...
 661         (conflicts_print): here.

 663
 664 2002-07-30  Akim Demaille  <akim@epita.fr>
 665
 666         Report rules which are never reduced by the parser: those hidden
 667         by conflicts.
 668
 669         * src/LR0.c (save_reductions): Don't make the final state too
 670         different: save its reduction (accept) instead of having a state
 671         without any action (no shift or goto, no reduce).
 672         Note: the final state is now a ``regular'' state, i.e., the
 673         parsers now contain `reduce 0' as default reduction.
 674         Nevertheless, since they decide to `accept' when yystate =
 675         final_state, they still will not reduce rule 0.
 676         * src/print.c (print_actions, print_reduction): Adjust.
 677         * src/output.c (action_row): Track reduced rules.

 685
 686         * configure.in: Look for malloc.h and sys/times.h.
 687         * src/main.c (stage): Adjust.
 688         Report only when trace_flag.

 705         (endtoken, accept): these.
 706         * src/reader.c (reader): Set endtoken's default tag to "$end".
 707         Set undeftoken's tag to "$undefined" instead of "$undefined.".
 708         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
 709         Adjust.
 710
 711 2002-07-29  Akim Demaille  <akim@epita.fr>
 712
 713         * src/reduce.c (reduce_grammar): When the language is empty,
 714         complain about the start symbol, not the axiom.
 715         Use its location.
 716         * tests/reduce.at (Empty Language): New.

 724         token_translations instead of `0'.
 725         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
 726         visible here.
 727         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
 728         for the time being: %locations ought to provide it to yyerror.
 729
 730 2002-07-25  Akim Demaille  <akim@epita.fr>
 731
 732         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1817         eccentricities.

1892
1893         Remove `%thong' support as it is undocumented, unused, duplicates
1894         `%token's job, and creates useless e-mail traffic with people who

2364         * src/gram.h, src/gram.c (grammar_dump): here.
2365         Be sure to separate long item numbers.

2367
2368 2002-04-22  Akim Demaille  <akim@epita.fr>
2369
2370         * src/output.c (table_size, table_grow): New.
2371         (MAXTABLE): Remove, replace uses with table_size.
2372         (pack_vector): Instead of dying when the table is too big, grow it.
2373
2374 2002-04-22  Akim Demaille  <akim@epita.fr>
2375
2376         * data/bison.simple (yyr1): Its type is that of a token number.
2377         * data/bison.c++ (r1_): Likewise.
2378         * tests/regression.at (Web2c Actions): Adjust.
2379
2380 2002-04-22  Akim Demaille  <akim@epita.fr>
2381
2382         * src/reader.c (token_translations_init): 256 is now the default
2383         value for the error token, i.e., it will be assigned another
2384         number if the user assigned 256 to one of her tokens.
2385         (reader): Don't force 256 to error.
2386         * doc/bison.texinfo (Symbols): Adjust.
2387         * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
2388         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
2389         etc. instead of 10, 20, 30 (which was used to `jump' over error
2390         (256) and undefined (2)).
2391
2392 2002-04-22  Akim Demaille  <akim@epita.fr>
2393
2394         Propagate more token_number_t.
2395
2396         * src/gram.h (token_number_as_item_number)
2397         (item_number_as_token_number): New.
2398         * src/output.c (GENERATE_OUTPUT_TABLE): New.
2399         Use it to create output_item_number_table and
2400         output_token_number_table.
2401         * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,
2402         * src/lex.c, src/nullable.c, src/output.c, src/print.c,

2404         * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.
2405
2406 2002-04-22  Akim Demaille  <akim@epita.fr>
2407
2408         * src/output.h, src/output.c (get_lines_number): Remove.
2409
2410 2002-04-19  Akim Demaille  <akim@epita.fr>
2411
2412         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
2413         as Lex/Flex'.
2414         (Debugging): More details about enabling the debugging features.
2415         (Table of Symbols): Describe $$, $n, @$, and @n.
2416         Suggested by Tim Josling.
2417
2418 2002-04-19  Akim Demaille  <akim@epita.fr>
2419
2420         * doc/bison.texinfo: Remove the uses of the obsolete @refill.

2422 2002-04-10  Akim Demaille  <akim@epita.fr>
2423
2424         * src/system.h: Rely on HAVE_LIMITS_H.
2425         Suggested by Paul Eggert.
2426
2427 2002-04-09  Akim Demaille  <akim@epita.fr>
2428
2429         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2430         full stderr, and strip it according to the bison options, instead
2431         of composing the error message from different bits.
2432         This makes it easier to check for several error messages.
2433         Adjust all the invocations.
2434         Add an invocation exercising the error token.
2435         Add an invocation demonstrating a stupid error message.
2436         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
2437         Adjust the tests.
2438         Error message are for stderr, not stdout.
2439
2440 2002-04-09  Akim Demaille  <akim@epita.fr>
2441
2442         * src/gram.h, src/gram.c (error_token_number): Remove, use
2443         errtoken->number.
2444         * src/reader.c (reader): Don't specify the user token number (2)
2445         for $undefined, as it uselessly prevents using it.
2446         * src/gram.h (token_number_t): Move to...
2447         * src/symtab.h: here.
2448         (state_t.number): Is a token_number_t.
2449         * src/print.c, src/reader.c: Use undeftoken->number instead of
2450         hard coded 2.
2451         (Even though this 2 is not the same as above: the number of the
2452         undeftoken remains being 2, it is its user token number which
2453         might not be 2).
2454         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2455         `user_token_number_max'.
2456         Output `undef_token_number'.
2457         * data/bison.simple, data/bison.c++: Use them.
2458         Be sure to map invalid yylex return values to
2459         `undef_token_number'.  This saves us from gratuitous SEGV.
2460
2461         * tests/conflicts.at (Solved SR Conflicts)
2462         (Unresolved SR Conflicts): Adjust.
2463         * tests/regression.at (Web2c Actions): Adjust.

2466
2467         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
2468         Adding #line.
2469         Remove the duplicate `typedefs'.
2470         (RhsNumberType): Fix the declaration and various other typos.
2471         Use __ofile__.
2472         * data/bison.simple: Use __ofile__.
2473         * src/scan-skel.l: Handle __ofile__.
2474
2475 2002-04-08  Akim Demaille  <akim@epita.fr>
2476
2477         * src/gram.h (item_number_t): New, the type of item numbers in
2478         RITEM.  Note that it must be able to code symbol numbers as
2479         positive number, and the negation of rule numbers as negative
2480         numbers.
2481         Adjust all dependencies (pretty many).
2482         * src/reduce.c (rule): Remove this `short *' pointer: use
2483         item_number_t.
2484         * src/system.h (MINSHORT, MAXSHORT): Remove.
2485         Include `limits.h'.
2486         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2487         (shortcpy): Remove.
2488         (MAXTABLE): Move to...
2489         * src/output.c (MAXTABLE): here.
2490         (prepare_rules): Use output_int_table to output rhs.
2491         * data/bison.simple, data/bison.c++: Adjust.
2492         * tests/torture.at (Big triangle): Move the limit from 254 to
2493         500.
2494         * tests/regression.at (Web2c Actions): Ajust.
2495
2496         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2497         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2498         passes, but produces negative #line number, once fixed, GCC is
2499         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2500         C), it passes.
2501         * src/state.h (state_h): Code input lines on ints, not shorts.
2502
2503 2002-04-08  Akim Demaille  <akim@epita.fr>
2504
2505         * src/reduce.c (reduce_grammar): First reduce the nonterminals,

2518         New.
2519         Use them to define yy_token_number_type/TokenNumberType.
2520         Use this type for yytranslate.
2521         * tests/torture.at (Big triangle): Push the limit from 124 to

2629 2002-04-07  Akim Demaille  <akim@epita.fr>
2630
2631         Be sure never to walk through RITEMS, but use only data related to
2632         the rules themselves. RITEMS should be banished.
2633
2634         * src/output.c (output_token_translations): Rename as...
2635         (prepare_tokens): this.
2636         In addition to `translate', prepare the muscles `tname' and

2639         Remove, and move the remainder of its outputs into...
2640         (prepare_rules): this new routines, which also merges content from

2649
2650         * src/LR0.c (new_state): Display `nstates' as the name of the
2651         newly created state.
2652         Adjust to initialize first_state and last_state if needed.
2653         Be sure to distinguish the initial from the final state.
2654         (new_states): Create the itemset of the initial state, and use
2655         new_state.
2656         * src/closure.c (closure): Now that the initial state has its
2657         items properly set, there is no need for a special case when
2658         creating `ruleset'.
2659
2660         As a result, now the rule 0, reducing to $axiom, is visible in the
2661         outputs.  Adjust the test suite.

2680         `number' of the buckets too.
2681         * src/gram.h: Include `symtab.h'.
2682         (associativity): Move to...

2694         (reduce_output, dump_grammar): Adjust.
2695         * src/print.c (print_grammar): It is no longer needed to check for
2696         the usefulness of a rule, as useless rules are beyond `nrules + 1'.

3002         causing more problems than it was curing, since it didn't work
3003         properly on some nonstandard C++ compilers.  This can wait

3060         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
3061
3062 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3063
3064         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
3065         C++ parsers.
3066         (yy::b4_name::parse): Build verbose error messages, and use error_.
3067
3068 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3069
3070         * data/bison.c++: Fix m4 quoting in comments.
3071
3072 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3073
3074         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
3075         not expanded by m4.
3076
3077 2002-02-05  Akim Demaille  <akim@epita.fr>
3078
3079         * data/bison.c++: Adjust to the M4 back end.
3080         More is certainly needed.
3081
3082 2002-02-05  Akim Demaille  <akim@epita.fr>
3083
3084         Give a try to M4 as a back end.
3085
3086         * lib/readpipe.c: New, from wdiff.
3087         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
3088         BISON_HAIRY.
3089         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
3090         specific values.  Now it is m4 that performs the lookup.
3091         * src/parse-skel.y: Remove.
3092         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
3093         * src/output.c (actions_output, guards_output)
3094         (token_definitions_output): No longer keeps track of the output
3095         line number, hence remove the second argument.
3096         (guards_output): Check against the guard member of a rule, not the
3097         action member.
3098         Adjust callers.
3099         (output_skeleton): Don't look for the skeleton location, let m4 do
3100         that.
3101         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
3102         file will be used.
3103         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3104         (prepare): Given that for the time being changesyntax is not
3105         usable in M4, rename the muscles using `-' to `_'.
3106         Define `defines_flag', `output_parser_name' and `output_header_name'.
3107         * src/output.h (actions_output, guards_output)
3108         (token_definitions_output): Adjust prototypes.
3109         * src/scan-skel.l: Instead of scanning the skeletons, it now
3110         processes the output of m4: `__oline__' and `#output'.
3111         * data/bison.simple: Adjust to be used by M4(sugar).
3112         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3113         to date.
3114         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3115         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
3116         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
3117         shamelessly stolen from CVS Autoconf.
3118
3119 2002-02-05  Akim Demaille  <akim@epita.fr>
3120
3121         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
3122         * configure.in: Check for the declarations of free and malloc.
3123         * src/muscle_tab.c: Adjust.
3124
3125 2002-02-05  Akim Demaille  <akim@epita.fr>
3126
3127         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
3128         which have no values.
3129
3130 2002-02-05  Akim Demaille  <akim@epita.fr>
3131
3132         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
3133         * data/: here.
3134
3135 2002-01-29  Paul Eggert  <eggert@twinsun.com>
3136
3137         * src/bison.simple (YYSIZE_T): Do not define merely because
3138         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3139         On some platforms, <alloca.h> does not declare YYSTD (size_t).
3140
3141 2002-01-27  Akim Demaille  <akim@epita.fr>
3142
3143         Fix `%nonassoc and eof'.
3144
3145         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
3146         which were not properly copied!  Replace
3147         memcpy (res->errs, src->errs, src->nerrs);
3148         with
3149         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3150         !!!
3151         * tests/regression.at (%nonassoc and eof): Adjust to newest
3152         Autotest: `.' is not in the PATH.
3153
3154 2002-01-27  Akim Demaille  <akim@epita.fr>
3155
3156         * tests/sets.at (AT_EXTRACT_SETS): New.
3157         (Nullable): Use it.
3158         (Firsts): New.
3159
3160 2002-01-26  Akim Demaille  <akim@epita.fr>
3161
3162         * tests/actions.at, tests/calc.at, tests/headers.at,
3163         * tests/torture.at: Adjust to the newest Autotest which no longer
3164         forces `.' in the PATH.
3165
3166 2002-01-25  Akim Demaille  <akim@epita.fr>
3167
3168         * tests/regression.at (%nonassoc and eof): New.
3169         Suggested by Robert Anisko.
3170
3171 2002-01-24  Akim Demaille  <akim@epita.fr>
3172
3173         Bison dumps core when trying to complain about broken input files.
3174         Reported by Cris van Pelt.
3175
3176         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
3177         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
3178         into...
3179         (Invalid inputs): Strengthen: exercise parse_percent_token.
3180
3181 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
3182
3183         * src/Makefile.am: Add bison.c++.
3184         * src/bison.c++: New skeleton.
3185
3186 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
3187
3188         * po/it.po: New.
3189
3190 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
3191
3192         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
3193
3194 2002-01-20  Marc Autret  <marc@gnu.org>
3195
3196         * src/files.c (compute_output_file_names): Fix
3197
3198 2002-01-20  Marc Autret  <marc@gnu.org>
3199
3200         * tests/output.at: New test.
3201         * src/files.c (compute_base_names): Don't map extensions when
3202         the YACC flag is set, use defaults.
3203         Reported by Evgeny Stambulchik.
3204
3205 2002-01-20  Marc Autret  <marc@gnu.org>
3206
3207         * src/system.h: Need to define __attribute__ away for non-GCC
3208         compilers as well (i.e. the vendor C compiler).
3209         Suggested by Albert Chin-A-Young.
3210
3211 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
3212
3213         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3214         canonical definition.
3215         * src/system.h: Use the canonical definition for PARAMS (avoids
3216         a conflict with the macro from lib/hash.h).
3217
3218 2002-01-11  Akim Demaille  <akim@epita.fr>
3219
3220         * configure.in: Use AC_FUNC_STRNLEN.
3221         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3222
3223 2002-01-09  Akim Demaille  <akim@epita.fr>
3224
3225         * src/files.c, src/files.h (output_infix): New.
3226         (tab_extension): Remove.
3227         (compute_base_names): Compute the former, drop the latter.
3228         * src/output.c (prepare): Insert the muscles `output-infix', and
3229         `output-suffix'.
3230         * src/parse-skel.y (string, string.1): New.
3231         (section.header): Use it.
3232         (section.yacc): Remove.
3233         (prefix): Remove too.
3234         * src/scan-skel.l: Adjust.
3235         * src/bison.simple, src/bison.hairy: Adjust.
3236
3237 2002-01-09  Akim Demaille  <akim@epita.fr>
3238
3239         * configure.in (WERROR_CFLAGS): Compute it.
3240         * src/Makefile.am (CFLAGS): Pass it.
3241         * tests/atlocal.in (CFLAGS): Idem.
3242         * src/files.c: Fix a few warnings.
3243         (get_extension_index): Remove, unused.
3244
3245 2002-01-08  Akim Demaille  <akim@epita.fr>
3246
3247         * src/getargs.c (AS_FILE_NAME): New.
3248         (getargs): Use it to convert DOSish file names.
3249         * src/files.c (base_name): Rename as full_base_name to avoid
3250         clashes with `base_name ()'.
3251         (filename_split): New.
3252         (compute_base_names): N-th rewrite, using filename_split.
3253
3254 2002-01-08  Akim Demaille  <akim@epita.fr>
3255
3256         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3257         New, stolen from the Fileutils 4.1.
3258         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3259         * configure.in: Check for the presence of memrchr, and of its
3260         prototype.
3261
3262 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3263
3264         * lib/hash.h (__P): Added definition for this macro.
3265         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3266         BUILT_SOURCES, to ensure they are generated first.
3267         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3268         %error-verbose to allow bootstrapping with bison 1.30x.
3269
3270 2002-01-06  Akim Demaille  <akim@epita.fr>
3271
3272         * src/reader.c (parse_braces): Don't fetch the next char, the
3273         convention is to fetch on entry.
3274         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3275         'switch' without a following semicolon.
3276         * tests/regression.at (braces parsing): New.
3277
3278 2002-01-06  Akim Demaille  <akim@epita.fr>
3279
3280         Bison is dead wrong in its RR conflict reports.
3281
3282         * tests/torture.at (GNU Cim Grammar): New.
3283         * src/conflicts.c (count_rr_conflicts): Fix.
3284
3285 2002-01-06  Akim Demaille  <akim@epita.fr>
3286
3287         Creating package.m4 from configure.ac causes too many problems.
3288
3289         * tests/Makefile.am (package.m4): Create it by hand,
3290         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3291
3292 2002-01-06  Akim Demaille  <akim@epita.fr>
3293
3294         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3295         skeleton.h.
3296
3297 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3298
3299         * doc/bison.texinfo (Debugging):
3300         Remove YYSTDERR; it's no longer defined or used.
3301         Also, s/cstdio.h/cstdio/.
3302
3303 2002-01-03  Akim Demaille  <akim@epita.fr>
3304
3305         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3306
3307 2002-01-03  Akim Demaille  <akim@epita.fr>
3308
3309         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3310         tracing code to --trace, wait for a better --trace option, with
3311         args.
3312
3313 2002-01-03  Akim Demaille  <akim@epita.fr>
3314
3315         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3316         The ISO C++ standard is extremely clear about it: stderr is
3317         considered a macro, not a regular symbol (see table 94 `Header
3318         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3319         Therefore std:: does not apply to it.  It still does with fprintf.
3320         Also, s/cstdio.h/cstdio/.
3321
3322 2002-01-03  Akim Demaille  <akim@epita.fr>
3323
3324         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3325         for non system headers.
3326
3327 2002-01-02  Akim Demaille  <akim@epita.fr>
3328
3329         Equip the skeleton chain with location tracking, runtime trace,
3330         pure parser and scanner.
3331
3332         * src/parse-skel.y: Request a pure parser, locations, and prefix
3333         renaming.
3334         (%union): Having several members with the same type does not help
3335         type mismatches, simplify.
3336         (YYPRINT, yyprint): New.
3337         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3338         (skel_error): this.
3339         Handle locations.
3340         * src/scan-skel.l: Adjust to these changes.
3341         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3342         (LOCATION_PRINT, skel_control_t): New.
3343
3344 2001-12-30  Akim Demaille  <akim@epita.fr>
3345
3346         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3347         replace `gb' with BLANKS.
3348         * src/scan-skel.l: Adjust.
3349
3350 2001-12-30  Akim Demaille  <akim@epita.fr>
3351
3352         * src/system.h: We don't need nor want bcopy.
3353         Throw away MS-DOS crap: we don't need getpid.
3354         * configure.in: We don't need strndup.  It was even causing
3355         problems: because Flex includes the headers *before* us,
3356         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3357         not visible.
3358         * lib/xstrndup.c: New.
3359         * src/scan-skel.l: Use it.
3360         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3361         * src/parse-skel.y: Use %directives instead of #defines.
3362
3363 2001-12-30  Akim Demaille  <akim@epita.fr>
3364
3365         * src/skeleton.h: New.
3366         * src/output.c (output_parser, output_master_parser): Remove, dead
3367         code.
3368         * src/output.h (get_lines_number, actions_output, guards_output)
3369         (token_definitions_output): Prototype them.
3370         * src/parse-skel.y: Add the license notice.
3371         Include output.h and skeleton.h.
3372         (process_skeleton): Returns void, and takes a single parameter.
3373         * src/scan-skel.l: Add the license notice.
3374         Include skeleton.h.
3375         Don't use %option yylineno: it seems that then Flex imagines
3376         REJECT has been used, and therefore it won't reallocate its
3377         buffers (which makes no other sense to me than a bug).  It results
3378         in warnings for `unused: yy_flex_realloc'.
3379
3380 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
3381
3382         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3383         (MUSCLE_INSERT_PREFIX): ...to there.
3384         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3385         (MUSCLE_INSERT_PREFIX): Move from here...
3386
3387         * src/bison.hairy: Add a section directive.  Put braces around muscle
3388         names.  This parser skeleton is still broken, but Bison should not
3389         choke on a bad muscle 'syntax'.
3390         * src/bison.simple: Add a section directive.  Put braces around muscle
3391         names.
3392
3393         * src/files.h (strsuffix, stringappend): Add declarations.
3394         (tab_extension): Add declaration.
3395         (short_base_name): Add declaration.
3396
3397         * src/files.c (strsuffix, stringappend): No longer static.  These
3398         functions are used in the skeleton parser.
3399         (tab_extension): New.
3400         (compute_base_names): Use the computations done in this function
3401         to guess if the generated parsers should have '.tab' in their
3402         names.
3403         (short_base_name): No longer static.
3404
3405         * src/output.c (output_skeleton): New.
3406         (output): Disable call to output_master_parser, and give a try to
3407         a new skeleton handling system.
3408         (guards_output, actions_output): No longer static.
3409         (token_definitions_output, get_lines_number): No longer static.
3410
3411         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3412
3413         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3414         parse-skel.y.
3415
3416         * src/parse-skel.y: New file.
3417         * src/scan-skel.l: New file.

3419 2001-12-29  Akim Demaille  <akim@epita.fr>
3420
3421         %name-prefix is broken.
3422
3423         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3424         Adjust all dependencies.
3425         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3426         %name-prefix.
3427
3428         Renaming yylval but not yylloc is not consistent.  Now we do.
3429
3430         * src/bison.simple: Prefix yylloc if used.
3431         * doc/bison.texinfo (Decl Summary): Document that.
3432
3433 2001-12-29  Akim Demaille  <akim@epita.fr>
3434
3435         * doc/bison.texinfo: Promote `%long-directive' over
3436         `%long_directive'.
3437         Remove all references to fixed-output-files, yacc is enough.
3438
3439 2001-12-29  Akim Demaille  <akim@epita.fr>
3440
3441         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3442         user prologue.  These are defaults.
3443         * tests/actions.at (Mid-rule actions): Make sure the user can
3444         define YYDEBUG and YYERROR_VERBOSE.
3445
3446 2001-12-29  Akim Demaille  <akim@epita.fr>
3447
3448         * src/output.c (header_output): Don't forget to export YYLTYPE and
3449         yylloc.
3450         * tests/headers.at (export YYLTYPE): New, make sure it does.
3451         * tests/regression.at (%union and --defines, Invalid CPP headers):
3452         Move to...
3453         * tests/headers.at: here.
3454
3455 2001-12-29  Akim Demaille  <akim@epita.fr>
3456
3457         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3458
3459 2001-12-29  Akim Demaille  <akim@epita.fr>
3460
3461         * tests/actions.at (Mid-rule actions): Output on a single line
3462         instead of several.
3463
3464 2001-12-29  Akim Demaille  <akim@epita.fr>
3465
3466         * doc/bison.texinfo: Formatting changes.
3467
3468 2001-12-29  Akim Demaille  <akim@epita.fr>
3469
3470         Don't store the token defs in a muscle, just be ready to output it
3471         on command.  Now possible via `symbols'.  Fixes a memory leak.
3472
3473         * src/output.c (token_definitions_output): New.
3474         (output_parser, header_output): Use it.
3475         * src/reader.c (symbols_save): Remove.
3476
3477 2001-12-29  Akim Demaille  <akim@epita.fr>
3478
3479         * src/bison.simple: Do not provide a default for YYSTYPE and
3480         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3481         default.
3482
3483 2001-12-29  Akim Demaille  <akim@epita.fr>
3484
3485         Mid-rule actions are simply... ignored!
3486
3487         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3488         the empty-rule associated to the dummy symbol, not to the host
3489         rule.
3490         * tests/actions.at (Mid-rule actions): New.
3491
3492 2001-12-29  Akim Demaille  <akim@epita.fr>
3493
3494         Memory leak.
3495
3496         * src/reader.c (reader): Free grammar.
3497
3498 2001-12-29  Akim Demaille  <akim@epita.fr>
3499
3500         Memory leak.
3501
3502         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3503         since it allocates it for each state, although only one is needed.
3504         (allocate_storage): Do it here.
3505
3506 2001-12-29  Akim Demaille  <akim@epita.fr>
3507
3508         * src/options.h, src/options.c (create_long_option_table): Rename
3509         as...
3510         (long_option_table_new): this, with a clearer prototype.
3511         (percent_table): Remove, unused,
3512         * src/getargs.c (getargs): Adjust.
3513
3514 2001-12-29  Akim Demaille  <akim@epita.fr>
3515
3516         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3517         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3518         as states.
3519
3520 2001-12-29  Akim Demaille  <akim@epita.fr>
3521
3522         * src/lalr.c (build_relations): Rename `states' as `states1'.
3523         Sorry, I don't understand exactly what it is, no better name...
3524
3525 2001-12-29  Akim Demaille  <akim@epita.fr>
3526
3527         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c

3529         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3530         as rules.
3531
3532 2001-12-29  Akim Demaille  <akim@epita.fr>
3533
3534         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3535         ago.
3536
3537 2001-12-29  Akim Demaille  <akim@epita.fr>
3538
3539         * src/reader.c, src/reader.h (user_toknums): Remove.
3540         Adjust all users to use symbols[i]->user_token_number.
3541
3542 2001-12-29  Akim Demaille  <akim@epita.fr>
3543
3544         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3545         Adjust all users to use symbols[i]->prec or ->assoc.
3546
3547 2001-12-29  Akim Demaille  <akim@epita.fr>
3548
3549         * src/reader.c, src/reader.h (tags): Remove.
3550         Adjust all users to use symbols[i]->tag.
3551
3552 2001-12-29  Akim Demaille  <akim@epita.fr>
3553
3554         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3555         and rule_table.
3556         * src/reader.c (packsymbols): Fill this table.
3557         Drop sprec.
3558         * src/conflicts.c (resolve_sr_conflict): Adjust.
3559         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3560         single table.
3561         Use symbols[i]->tag instead of tags[i].
3562
3563 2001-12-29  Akim Demaille  <akim@epita.fr>
3564
3565         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3566         In addition, put a comment in there, to replace...
3567         * tests/regression.at (%union and C comments): Remove.
3568
3569 2001-12-29  Akim Demaille  <akim@epita.fr>
3570
3571         * tests/regression.at (Web2c Actions): Blindly move the actual
3572         output as expected output.  The contents *seem* right to me, but I
3573         can't pretend reading perfectly parser tables...  Nonetheless, all
3574         the other tests pass correctly, the table look OK, even though the
3575         presence of `$axiom' is to be noted: AFAICS it is useless (but
3576         harmless).
3577
3578 2001-12-29  Akim Demaille  <akim@epita.fr>
3579
3580         * src/reader.c (readgram): Don't add the rule 0 if there were no
3581         rules read.  In other words, add it _after_ having performed
3582         grammar sanity checks.
3583         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3584
3585 2001-12-29  Akim Demaille  <akim@epita.fr>
3586
3587         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3588         visible, and some states have now a different number.
3589
3590 2001-12-29  Akim Demaille  <akim@epita.fr>
3591
3592         * src/reader.c (readgram): Bind the initial rule's lineno to that
3593         of the first rule.
3594         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3595         (Solved SR Conflicts): Adjust rule 0's line number.
3596
3597 2001-12-29  Akim Demaille  <akim@epita.fr>
3598
3599         Fix the `GAWK Grammar' failure.
3600
3601         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3602         the reductions of the first state which was mistakenly confused
3603         with the final state because precisely final_state was initialized
3604         to 0.
3605         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3606         now noticed by Bison.
3607         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3608         have a reduction on $default.
3609
3610 2001-12-29  Akim Demaille  <akim@epita.fr>
3611
3612         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3613         rule line numbers.
3614         * src/closure.c (print_closure): Likewise.
3615         * src/derives.c (print_derives): Likewise.
3616         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3617         now.
3618
3619 2001-12-29  Akim Demaille  <akim@epita.fr>
3620
3621         * src/lalr.c (lookaheads_print): New.
3622         (lalr): Call it when --trace-flag.
3623         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3624         are dumped.
3625
3626 2001-12-29  Akim Demaille  <akim@epita.fr>
3627
3628         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3629         when walking through ritem, even via rule->rhs.
3630         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3631         (useful_production, useless_nonterminals): Likewise.
3632         (reduce_grammar_tables): Likewise, plus update nritems.
3633         * src/nullable.c (set_nullable): Likewise.
3634         * src/lalr.c (build_relations): Likewise.
3635         * tests/sets.at (Nullable): Adjust.
3636         Fortunately, now, the $axiom is no longer nullable.
3637
3638 2001-12-29  Akim Demaille  <akim@epita.fr>
3639
3640         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3641         the 0-sentinel.
3642         * src/gram.c (ritem_longest_rhs): Likewise.
3643         * src/reduce.c (nonterminals_reduce): Likewise.
3644         * src/print_graph.c (print_graph): Likewise.
3645         * src/output.c (output_rule_data): Likewise.
3646         * src/nullable.c (set_nullable):  Likewise.
3647
3648 2001-12-29  Akim Demaille  <akim@epita.fr>
3649
3650         * src/output.c: Comment changes.
3651
3652 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3653
3654         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3655         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3656         Sparc, as they were causing more porting problems than the
3657         (minor) performance improvement was worth.
3658
3659         Also, catch up with 1.31's YYSTD.
3660
3661 2001-12-27  Akim Demaille  <akim@epita.fr>
3662
3663         * src/output.c (output_gram): Rely on nritems, not the
3664         0-sentinel.  See below.
3665         Use -1 as separator, not 0.
3666         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3667         Rely on -1 as separator in yyrhs, instead of 0.
3668         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3669         twice `Now at end of input', therefore there are two lines less to
3670         expect.
3671
3672 2001-12-27  Akim Demaille  <akim@epita.fr>
3673
3674         * tests/regression.at (Unresolved SR Conflicts):
3675         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3676         below.
3677
3678 2001-12-27  Akim Demaille  <akim@epita.fr>
3679
3680         * src/LR0.c (new_state): Recognize the final state by the fact it
3681         is reached by eoftoken.
3682         (insert_start_shifting_state, insert_eof_shifting_state)
3683         (insert_accepting_state, augment_automaton): Remove, since now
3684         these states are automatically computed from the initial state.
3685         (generate_states): Adjust.
3686         * src/print.c: When reporting a rule number to the user, substract
3687         1, so that the axiom rule is rule 0, and the first user rule is 1.
3688         * src/reduce.c: Likewise.
3689         * src/print_graph.c (print_core): For the time being, just as for
3690         the report, depend upon --trace-flags to dump the full set of
3691         items.
3692         * src/reader.c (readgram): Once the grammar read, insert the rule
3693         0: `$axiom: START-SYMBOL $'.
3694         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3695         number of the states has changed (the final state is no longer
3696         necessarily the last), catch up.
3697
3698 2001-12-27  Akim Demaille  <akim@epita.fr>
3699
3700         Try to make the use of the eoftoken valid.  Given that its value
3701         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3702         is used instead of > 0 where appropriate, (ii), depend upon nritems
3703         instead of the 0-sentinel.
3704
3705         * src/gram.h, src/gram.c (nritems): New.
3706         Expected to be duplication of nitems, but for the time being...
3707         * src/reader.c (packgram): Assert nritems and nitems are equal.
3708         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3709         * src/closure.c (print_closure, print_fderives): Likewise.
3710         * src/gram.c (ritem_print): Likewise.
3711         * src/print.c (print_core, print_grammar): Likewise.
3712         * src/print_graph.c: Likewise.
3713
3714 2001-12-27  Akim Demaille  <akim@epita.fr>
3715
3716         * src/main.c (main): If there are complains after grammar
3717         reductions, then output the report anyway if requested, then die.
3718         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3719         * src/reader.c (eoftoken): New.
3720         (parse_token_decl): If the token being defined has value `0', it
3721         is the eoftoken.
3722         (packsymbols): No longer hack `tags' to insert `$' by hand.
3723         Be sure to preserve the value of the eoftoken.
3724         (reader): Make sure eoftoken is defined.
3725         Initialize nsyms to 0: now eoftoken is created just like the others.
3726         * src/print.c (print_grammar): Don't special case the eof token.
3727         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3728         lie anyway, albeit pleasant.
3729         * tests/calc.at: Exercise error messages with eoftoken.
3730         Change the grammar so that empty input is invalid.
3731         Adjust expectations.
3732         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3733
3734 2001-12-27  Akim Demaille  <akim@epita.fr>
3735
3736         * configure.in: Check the protos of strchr ans strspn.
3737         Replace strchr if needed.
3738         * src/system.h: Provide the protos of strchr, strspn and memchr if
3739         missing.
3740         * lib/strchr.c: New.
3741         * src/reader.c (symbols_save): Use strchr.
3742
3743 2001-12-27  Akim Demaille  <akim@epita.fr>
3744
3745         * src/print.c, src/print_graph.c (escape): New.
3746         Use it to quote the TAGS outputs.
3747         * src/print_graph.c (print_state): Now errors are in red, and
3748         reductions in green.
3749         Prefer high to wide: output the state number on a line of its own.
3750
3751 2001-12-27  Akim Demaille  <akim@epita.fr>
3752
3753         * src/state.h, src/state.c (reductions_new): New.
3754         * src/LR0.c (set_state_table): Let all the states have a
3755         `reductions', even if reduced to 0.
3756         (save_reductions): Adjust.
3757         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

3759         * src/output.c (action_row): Adjust.
3760
3761 2001-12-27  Akim Demaille  <akim@epita.fr>
3762
3763         * src/state.h, src/state.c (errs_new, errs_dup): New.
3764         * src/LR0.c (set_state_table): Let all the states have an errs,
3765         even if reduced to 0.
3766         * src/print.c (print_errs, print_reductions): Adjust.
3767         * src/output.c (output_actions, action_row): Adjust.
3768         * src/conflicts.c (resolve_sr_conflict): Adjust.
3769
3770 2001-12-27  Akim Demaille  <akim@epita.fr>
3771
3772         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3773
3774 2001-12-27  Akim Demaille  <akim@epita.fr>
3775
3776         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3777         * src/print.c: here.
3778         (lookaheadset, shiftset): New, used as additional storage by
3779         print_reductions.
3780         (print_results): Adjust.
3781         (print_shifts, print_gotos, print_errs): New, extracted from...
3782         (print_actions): here.
3783         * src/print_graph.c (print_actions): Remove dead code.
3784
3785 2001-12-27  Akim Demaille  <akim@epita.fr>
3786
3787         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3788         `$n' and `@n'.
3789
3790 2001-12-27  Akim Demaille  <akim@epita.fr>
3791
3792         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3793         (build_relations): Adjust.
3794
3795 2001-12-27  Akim Demaille  <akim@epita.fr>
3796
3797         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3798         duplication.
3799
3800 2001-12-27  Akim Demaille  <akim@epita.fr>
3801
3802         * src/reader.c (packgram): Catch nitems overflows.
3803
3804 2001-12-27  Akim Demaille  <akim@epita.fr>
3805
3806         * src/files.c, src/files.h (guard_obstack): Remove.
3807         * src/output.c (output): Adjust.
3808         * src/reader.c (parse_braces): New, factoring...
3809         (copy_action, copy_guard): these two which are renamed as...
3810         (parse_action, parse_guard): these.
3811         As a voluntary consequence, using braces around guards is now
3812         mandatory.
3813
3814 2001-12-27  Akim Demaille  <akim@epita.fr>
3815
3816         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3817         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3818         members.
3819         (symbol_list_new): Adjust.
3820         (copy_action): action_line is the first line, not the last.
3821         (copy_guard): Just as for actions, store the `action' only, not
3822         the switch/case/break flesh.
3823         Don't parse the user action that might follow the guard, let...
3824         (readgram): do it, i.e., now, there can be an action after a
3825         guard.
3826         In other words the guard is just explicitly optional.
3827         (packgram): Adjust.
3828         * src/output.c (guards_output): New.
3829         (output_parser): Call it when needed.
3830         (output): Also free the guard and attrs obstacks.
3831         * src/files.c, src/files.h (obstack_save): Remove.
3832         (output_files): Remove.
3833         As a result, if one needs the former `.act' file, using an
3834         appropriate skeleton which requires actions and guards is now
3835         required.
3836         * src/main.c (main): Adjust.
3837         * tests/semantic.at: New.
3838         * tests/regression.at: Use `input.y' as input file name.
3839         Avoid 8+3 problems by requiring input.c when the test needs the
3840         parser.
3841
3842 2001-12-27  Akim Demaille  <akim@epita.fr>
3843
3844         * src/reader.c (symbol_list_new): Be sure to initialize all the
3845         fields.
3846
3847 2001-12-27  Akim Demaille  <akim@epita.fr>
3848
3849         All the hacks using a final pseudo state are now useless.
3850
3851         * src/LR0.c (set_state_table): state_table holds exactly nstates.
3852         * src/lalr.c (nLA): New.
3853         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3854         instead of lookaheadsp from the pseudo state (nstate + 1).
3855
3856 2001-12-27  Akim Demaille  <akim@epita.fr>
3857
3858         * src/output.c (action_row, token_actions): Use a state_t instead
3859         of a integer, and nlookaheads instead of the following state's
3860         lookaheadsp.
3861
3862 2001-12-27  Akim Demaille  <akim@epita.fr>

3866         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3867         (conflicts_print, print_reductions): Use a state_t instead of an
3868         integer when referring to a state.
3869         As much as possible, depend upon nlookaheads, instead of the
3870         `lookaheadsp' member of the following state (since lookaheads of
3871         successive states are successive, the difference between state n + 1
3872         and n served as the number of lookaheads for state n).
3873         * src/lalr.c (add_lookback_edge): Likewise.
3874         * src/print.c (print_core, print_actions, print_state)
3875         (print_results): Likewise.
3876         * src/print_graph.c (print_core, print_actions, print_state)
3877         (print_graph): Likewise.
3878         * src/conflicts.h: Adjust.

3880 2001-12-27  Akim Demaille  <akim@epita.fr>
3881
3882         * src/bison.hairy: Formatting/comment changes.
3883         ANSIfy.
3884         Remove `register' indications.
3885         Add plenty of `static'.
3886
3887 2001-12-27  Akim Demaille  <akim@epita.fr>
3888
3889         * src/output.c (prepare): Drop the muscle `ntbase' which
3890         duplicates ntokens.
3891         * src/bison.simple: Formatting/comment changes.
3892         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3893         is an undocumented synonym.
3894
3895 2001-12-22  Akim Demaille  <akim@epita.fr>
3896
3897         * src/output.c (output_table_data): Change the prototype to use
3898         `int' for array ranges: some invocations do pass an int, not a
3899         short.
3900         Reported by Wayne Green.

3908         * tests/regression.at (Web2c): Rename as...
3909         (Web2c Report): this.
3910         (Web2c Actions): New.

3921
3922         Some host fail on `assert (!"foo")', which expands to
3923         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3924         Reported by Nelson Beebee.
3925
3926         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3927         `#define it_succeeded 0' and `assert (it_succeeded)'.
3928
3929 2001-12-17  Marc Autret  <autret_m@epita.fr>
3930
3931         * src/bison.simple: Don't hard code the skeleton line and filename.
3932         * src/output.c (output_parser): Rename 'line' as 'output_line'.
3933         New line counter 'skeleton_line' (skeleton-line muscle).
3934
3935 2001-12-17  Paul Eggert  <eggert@twinsun.com>
3936
3937         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3938         YYDEBUG must be defined to a nonzero value.
3939
3940         * src/bison.simple (yytname): Do not assume that the user defines
3941         YYDEBUG to a properly parenthesized expression.
3942
3943 2001-12-17  Akim Demaille  <akim@epita.fr>
3944
3945         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3946         nlookaheads is a new member.
3947         Adjust all users.
3948         * src/lalr.h (nlookaheads): Remove this orphan declaration.

3955         * src/main.c (main): Don't open/close files, nor invoke lex_free,
3956         let...
3957         * src/reader.c (reader): Do it.
3958
3959 2001-12-17  Akim Demaille  <akim@epita.fr>
3960

3970
3971         * src/output.c (output_obstack): Be static and rename as...

3973         output_obstack.
3974         * src/reader.h (muscle_obstack): Move to...
3975         * src/output.h: here, since it's defined in output.c.
3976
3977 2001-12-17  Akim Demaille  <akim@epita.fr>
3978
3979         * src/output.c (action_row, save_column, default_goto)

4000 2001-12-16  Marc Autret  <autret_m@epita.fr>
4001
4002         * src/bison.simple: Remove a useless #line directive.
4003         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4004         * src/output.c (get_lines_number): New.
4005         (output_parser): Adjust, now takes care about the lines of a
4006         output muscles.
4007         Fix line numbering.

4020 2001-12-15  Akim Demaille  <akim@epita.fr>
4021
4022         Make `make distcheck' work.
4023
4024         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4025         system.h which uses libgettext.h.
4026
4027 2001-12-15  Akim Demaille  <akim@epita.fr>
4028
4029         * src/nullable.c (set_nullable): Useless rules must be skipped,
4030         otherwise, since we range over their symbols, we might look at a
4031         nonterminal which no longer ``exists'', i.e., it is not counted in
4032         `nvars', hence we overflow our arrays.

4042         * src/reader.c (parse_union_decl): No longer output to
4043         defines_obstack: its content can be found in the `stype' muscle
4044         anyway.
4045         (output_token_translations): Merge into...
4046         (symbols_output): this.

4054
4055         * src/reader.c (parse_union_decl): Instead of handling two obstack
4056         simultaneously, use one to define the `stype' muscle, and use the
4057         value of the latter to fill defines_obstack.
4058         (copy_comment): Remove.
4059         (copy_comment2): Work for a single obstack.

4069
4070         Still making progress in separating Bison into (i) input, (ii)
4071         process, (iii) output: now we can directly output the parser file
4072         without using table_obstack at all.
4073
4074         * src/files.c, src/files.h (table_obstack): Bye bye.
4075         (parser_file_name): New.
4076         * src/files.c (compute_output_file_names): Compute it.

4079
4080 2001-12-15  Akim Demaille  <akim@epita.fr>
4081
4082         Attach actions to rules, instead of pre-outputting them to
4083         actions_obstack.
4084
4085         * src/gram.h (rule_t): action and action_line are new members.
4086         * src/reader.c (symbol_list): Likewise.
4087         (copy_action): Save the actions within the rule.
4088         (packgram): Save them in rule_table.
4089         * src/output.c (actions_output): New.
4090         (output_parser): Use it on `%%actions'.
4091         (output_rule_data): Don't free rule_table.
4092         (output): Do it.
4093         (prepare): Don't save the `action' muscle.
4094         * src/bison.simple: s/%%action/%%actions/.
4095
4096 2001-12-15  Akim Demaille  <akim@epita.fr>
4097
4098         * src/reader.c (copy_action): When --yacc, don't append a `;'
4099         to the user action: let it fail if lacking.
4100         Suggested by Arnold Robbins and Tom Tromey.
4101
4102 2001-12-14  Akim Demaille  <akim@epita.fr>
4103
4104         * src/lex.c (literalchar): Simply return the char you decoded, non
4105         longer mess around with obstacks and int pointers.
4106         Adjust all callers.

4110         * src/lex.c (literalchar): Don't escape the special characters,
4111         just decode them, and keep them as char (before, eol was output as
4112         the 2 char string `\n' etc.).
4113         * src/output.c (output_rule_data): Use quotearg to output the
4114         token strings.
4115
4116 2001-12-13  Paul Eggert  <eggert@twinsun.com>
4117
4118         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4119         Do not infringe on the global user namespace when using C++.
4120         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4121         All uses of `fprintf' and `stderr' changed.
4122
4123         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4124
4125 2001-12-13  Akim Demaille  <akim@epita.fr>
4126
4127         The computation of nullable is broken: it doesn't handle empty
4128         RHS's properly.
4129
4130         * tests/torture.at (GNU AWK Grammar): New.
4131         * tests/sets.at (Nullable): New.
4132         * src/nullable.c (set_nullable): Instead of blindly looping over
4133         `ritems', loop over the rules, and then over their rhs's.
4134
4135         Work around Autotest bugs.
4136
4137         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4138         frame, because Autotest understand lines starting with a `+' as
4139         traces from the shell.  Then, they are not processed properly.
4140         Admittedly an Autotest bug, but we don't have time to wait for
4141         Autotest to catch up.
4142         * tests/regression.at (Broken Closure): Adjust to the new table
4143         frames.
4144         Move to...
4145         * tests/sets.at: here.
4146
4147 2001-12-13  Akim Demaille  <akim@epita.fr>
4148
4149         * src/closure.c (closure): Use nrules instead of playing tricks
4150         with BITS_PER_WORD.
4151
4152 2001-12-13  Akim Demaille  <akim@epita.fr>
4153
4154         * src/print.c (print_actions): Output the handling of `$' as the
4155         traces do: shifting the token EOF.  Before EOF was treated as a
4156         nonterminal.
4157         * tests/regression.at: Adjust some tests.
4158         * src/print_graph.c (print_core): Complete the set of items via
4159         closure.  The next-to-final and final states are still unsatisfying,
4160         but that's to be addressed elsewhere.
4161         No longer output the rule numbers, but do output the state number.
4162         A single loop for the shifts + gotos is enough, but picked a
4163         distinct color for each.
4164         (print_graph): Initialize and finalize closure.
4165
4166 2001-12-13  Akim Demaille  <akim@epita.fr>
4167
4168         * src/reader.c (readgram): Remove dead code, an strip useless
4169         braces.
4170         (get_type): Remove, unused.
4171
4172 2001-12-12  Akim Demaille  <akim@epita.fr>
4173
4174         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4175         on that of lib/error.c.
4176
4177 2001-12-12  Akim Demaille  <akim@epita.fr>
4178
4179         Some hosts don't like `/' in includes.
4180
4181         * src/system.h: Include libgettext.h without qualifying the path.
4182         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4183         $(top_srcdir).
4184
4185 2001-12-11  Marc Autret  <autret_m@epita.fr>
4186
4187         * src/output.c (output_parser): Remove useless muscle.
4188
4189 2001-12-11  Marc Autret  <autret_m@epita.fr>
4190
4191         * src/bison.simple: Remove #line just before %%epilogue. It
4192         is now handled in ...
4193         * src/reader.c (read_additionnal_code): Add the output of a
4194         #line for the epilogue.
4195
4196 2001-12-10  Marc Autret  <autret_m@epita.fr>
4197
4198         * src/reader.c (copy_definition): Re-use CPP-outed code which
4199         replace precedent remove.
4200         * src/bison.simple: Remove #line before %%prologue because
4201         %%input-line is wrong at this time.
4202
4203 2001-12-10  Marc Autret  <autret_m@epita.fr>
4204
4205         * src/reader.c (symbols_output): Clean up.
4206         * src/output.c (output_gram, output): Clean up.
4207
4208 2001-12-10  Akim Demaille  <akim@epita.fr>
4209
4210         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
4211         * src/LR0.c (set_state_table): here.
4212         * src/lalr.c (lalr): Call it.
4213
4214 2001-12-10  Akim Demaille  <akim@epita.fr>
4215
4216         * src/state.h (shifts): Remove the `number' member: shifts are
4217         attached to state, hence no longer need to be labelled with a
4218         state number.
4219
4220 2001-12-10  Akim Demaille  <akim@epita.fr>
4221
4222         Now that states have a complete set of members, the linked list of
4223         shifts is useless: just fill directly the state's shifts member.
4224
4225         * src/state.h (shifts): Remove the `next' member.
4226         * src/LR0.c (first_state, last_state): Remove.
4227         Adjust the callers.
4228         (augment_automaton): Don't look for the shifts that must be added
4229         a shift on EOF: it is those of the state we looked for!  But now,
4230         since shifts are attached, it is no longer needed to looking
4231         merely by its id: its number.
4232
4233 2001-12-10  Akim Demaille  <akim@epita.fr>
4234
4235         * src/LR0.c (augment_automaton): Better variable locality.
4236         Remove an impossible branch: if there is a state corresponding to
4237         the start symbol being shifted, then there is shift for the start
4238         symbol from the initial state.
4239
4240 2001-12-10  Akim Demaille  <akim@epita.fr>
4241
4242         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4243         only when appropriate: when insert_start_shifting_state' is not
4244         invoked.
4245         * tests/regression.at (Rule Line Numbers): Adjust.
4246
4247 2001-12-10  Akim Demaille  <akim@epita.fr>
4248
4249         * src/LR0.c (augment_automaton): Now that all states have shifts,
4250         merge the two cases addition shifts to the initial state.
4251
4252 2001-12-10  Akim Demaille  <akim@epita.fr>
4253
4254         * src/lalr.c (set_state_table): Move to...
4255         * src/LR0.c: here.
4256         * src/lalr.c (lalr): Don't call it...
4257         * src/LR0.c (generate_states): do it.
4258         * src/LR0.h (first_state): Remove, only the table is used.
4259
4260 2001-12-10  Akim Demaille  <akim@epita.fr>
4261
4262         * src/LR0.h (first_shift, first_reduction): Remove.
4263         * src/lalr.c: Don't use first_shift: find shifts through the
4264         states.
4265
4266 2001-12-10  Akim Demaille  <akim@epita.fr>
4267
4268         * src/LR0.c: Attach shifts to states as soon as they are
4269         computed.
4270         * src/lalr.c (set_state_table): Instead of assigning shifts to
4271         state, just assert that the mapping was properly done.
4272
4273 2001-12-10  Akim Demaille  <akim@epita.fr>
4274
4275         * src/LR0.c (insert_start_shift): Rename as...
4276         (insert_start_shifting_state): this.
4277         (insert_eof_shifting_state, insert_accepting_state): New.
4278         (augment_automaton): Adjust.
4279         Better locality of the variables.
4280         When looking if the start_symbol is shifted from the initial
4281         state, using `while (... symbol != start_symbol ...)' sounds
4282         better than `while (... symbol < start_symbol ...)': If fail
4283         to see how the order between symbols could be relevant!
4284
4285 2001-12-10  Akim Demaille  <akim@epita.fr>
4286
4287         * src/getargs.h: Don't declare `spec_name_prefix' and
4288         `spec_file_prefix', declared by src/files.h.
4289         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4290         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4291         * src/output.c (prepare): Adjust.
4292         * src/reader.c (symbols_output): Likewise.
4293         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4294
4295 2001-12-10  Akim Demaille  <akim@epita.fr>
4296
4297         * src/muscle_tab.c (muscle_init): NULL is a better default than
4298         `"0"'.
4299
4300 2001-12-10  Akim Demaille  <akim@epita.fr>
4301
4302         * src/reader.c (reader): Calling symbols_output once is enough.
4303
4304 2001-12-10  Akim Demaille  <akim@epita.fr>
4305
4306         Now that states have a complete set of members, the linked list of
4307         reductions is useless: just fill directly the state's reductions
4308         member.
4309
4310         * src/state.h (struct reductions): Remove member `number' and
4311         `next'.
4312         * src/LR0.c (first_reduction, last_reduction): Remove.
4313         (save_reductions): Don't link the new reductions, store them in
4314         this_state.
4315         * src/lalr.c (set_state_table): No need to attach reductions to
4316         states, it's already done.
4317         * src/output.c (output_actions): No longer free the shifts, then
4318         the reductions, then the states: free all the states and their
4319         members.
4320
4321 2001-12-10  Akim Demaille  <akim@epita.fr>
4322
4323         * src/options.c (OPTN, DRTV, BOTH): New.
4324         (option_table): Use them.
4325
4326         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4327         the job of system.h.
4328         * src/options.c: Don't include stdio.h and xalloc.h for the same
4329         reasons.
4330
4331 2001-12-10  Akim Demaille  <akim@epita.fr>
4332
4333         * src/output.c (output, prepare): Make sure the values of the
4334         muscles `action' and `prologue' are 0-terminated.
4335
4336 2001-12-10  Akim Demaille  <akim@epita.fr>
4337
4338         Clean up GCC warnings.
4339
4340         * src/reader.c (copy_action): `buf' is not used.
4341         (parse_skel_decl): Be static.
4342         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4343         * src/options.h (create_long_option_table): Have a real prototype.
4344         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4345         (hash_delete_at): Return const void *.
4346         Adjust casts to preserve the const.
4347
4348 2001-12-10  Akim Demaille  <akim@epita.fr>
4349
4350         * configure.in: Require 2.52g.
4351         M4 is not needed, but AUTOM4TE is.
4352         * m4/m4.m4: Remove.
4353         * tests/Makefile.am: Adjust.
4354
4355 2001-12-10  Akim Demaille  <akim@epita.fr>
4356
4357         One structure for states is enough, even though theoretically
4358         there are LR(0) states and LALR(1) states.
4359
4360         * src/lalr.h (state_t): Remove.
4361         (state_table): Be state_t **, not state_t *.
4362         * src/state.h (core, CORE_ALLOC): Rename as...
4363         (state_t, STATE_ALLOC): this.
4364         Add the LALR(1) members: shifts, reductions, errs.
4365         * src/LR0.c (state_table): Rename as...
4366         (state_hash): this, to avoid name clashes with the global
4367         `state_table'.
4368         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4369         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
4370
4371 2001-12-10  Akim Demaille  <akim@epita.fr>
4372
4373         Bison dumps core on bash.y.
4374         Reported by Pascal Bart.
4375
4376         * src/warshall.c (bitmatrix_print): New.
4377         (TC): Use it.
4378         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4379         j must be the outer loop.
4380         * tests/regression.at (Broken Closure): New.
4381
4382 2001-12-05  Akim Demaille  <akim@epita.fr>
4383
4384         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4385         its argument.
4386         Reported by Peter Hámorský.
4387
4388 2001-12-05  Akim Demaille  <akim@epita.fr>
4389
4390         * src/conflicts.c (err_table): Remove.
4391         (resolve_sr_conflict): Adjust.
4392         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4393         Rename as...
4394         (state_t.reductions, state_t.shifts): this.
4395
4396 2001-12-05  Akim Demaille  <akim@epita.fr>
4397
4398         * src/reduce.c (reduce_grammar_tables): No longer disable the
4399         removal of useless rules via CPP but via `if (0)', so that the
4400         compiler still check the code is valid.
4401         For instance, it should have noticed `rline' no longer exists: use
4402         the `line' member of rule_t.
4403         * src/gram.c (dummy, rline): Remove, unused.
4404
4405 2001-12-05  Akim Demaille  <akim@epita.fr>
4406
4407         * src/output.c (pack_vector): Use assert, not berror.
4408         * src/main.c (berror): Remove, unused.
4409
4410 2001-12-05  Akim Demaille  <akim@epita.fr>
4411
4412         New experimental feature: if --verbose --trace output all the
4413         items of a state, not only its kernel.
4414
4415         * src/print.c (print_core): If `trace_flag', then invoke closure
4416         before outputting the items of the state (print_core is no longer
4417         a correct name them).
4418         (print_results): Invoke new_closure/free_closure if needed.
4419
4420 2001-12-05  Akim Demaille  <akim@epita.fr>
4421
4422         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4423         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4424         (nitemset): for consistency with the rest of the project.
4425
4426 2001-12-05  Akim Demaille  <akim@epita.fr>
4427
4428         * src/closure.c (print_closure): Improve.
4429         (closure): Use it for printing input and output.
4430
4431 2001-12-05  Akim Demaille  <akim@epita.fr>
4432
4433         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4434         indexed by nonterminals.
4435
4436 2001-12-05  Akim Demaille  <akim@epita.fr>
4437
4438         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4439         what it was!).
4440         * src/warshall.h: Remove accidental duplication of the content.
4441
4442 2001-12-05  Akim Demaille  <akim@epita.fr>
4443
4444         * src/closure.c (set_fderives): De-obfuscate.
4445
4446 2001-12-05  Akim Demaille  <akim@epita.fr>
4447
4448         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
4449
4450 2001-12-05  Akim Demaille  <akim@epita.fr>
4451
4452         * src/closure.c (set_firsts): De-obfuscate.
4453
4454 2001-12-05  Akim Demaille  <akim@epita.fr>
4455
4456         * src/output.c (action_row): De-obfuscate
4457         using the good o' techniques: arrays not pointers, variable
4458         locality, BITISSET, RESETBIT etc.
4459
4460 2001-12-05  Akim Demaille  <akim@epita.fr>
4461
4462         Pessimize the code to simplify it: from now on, all the states
4463         have a valid SHIFTS, which NSHIFTS is possibly 0.

4471
4472         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4473         * src/conflicts.c: Use it.
4474         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4475         incorrectly ``simplified''.
4476
4477 2001-12-05  Akim Demaille  <akim@epita.fr>
4478
4479         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4480         using the good o' techniques: arrays not pointers, variable
4481         locality, BITISSET, RESETBIT etc.
4482
4483 2001-12-05  Akim Demaille  <akim@epita.fr>
4484
4485         * src/state.h (SHIFT_SYMBOL): New.

4487
4488 2001-12-05  Akim Demaille  <akim@epita.fr>
4489
4490         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4491         (print_reductions): De-obfuscate using the good o' techniques:
4492         arrays not pointers, variable locality, BITISSET.
4493
4494 2001-12-05  Akim Demaille  <akim@epita.fr>

4536
4537 2001-12-05  Akim Demaille  <akim@epita.fr>
4538
4539         * src/lalr.c (transpose): Free the memory allocated to the
4540         argument, as it is replaced by the results by the unique caller.
4541         (build_relations): Merely invoke transpose: it handles the memory
4542         deallocation.
4543         Improve variable locality.
4544         Avoid variables used as mere abbreviations.
4545         (compute_lookaheads): Use arrays instead of pointers.

4566         the handling of squeue.
4567         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4568
4569 2001-12-05  Akim Demaille  <akim@epita.fr>
4570
4571         Because useless nonterminals are now kept alive (instead of being
4572         `destroyed'), we now sometimes examine them, and store information
4573         related to them.  Hence we need to know their number, and adjust
4574         memory allocations.
4575
4576         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4577         static.
4578         * src/LR0.c (allocate_itemsets): The memory allocated to
4579         `symbol_count' was used for two different purpose: once to count
4580         the number of occurrences of each symbol, and later reassigned to
4581         `shift_symbol', containing the symbol that can be shifted from a
4582         given state.
4583         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4584         only, and...
4585         (new_itemsets): Allocate `shift_symbol' here.
4586         (allocate_itemsets): symbol_count includes useless nonterminals.
4587         Make room for them.
4588         (free_storage): Use `free', not `XFREE', for pointers that cannot
4589         be null.

4591 2001-12-05  Akim Demaille  <akim@epita.fr>
4592
4593         * src/nullable.c (set_nullable): Deobfuscate the handling of
4594         ritem.
4595         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4596
4597 2001-12-05  Akim Demaille  <akim@epita.fr>
4598
4599         * src/gram.c, src/gram.h (ritem_print): New.
4600         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4601         (This useless function was defined only to work around VMS linkers
4602         that can't handle compilation units with variables only).
4603         * src/reduce.c (dump_grammar): Use it to trace the construction of
4604         ritem.
4605
4606 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4607
4608         * src/bison.simple (union yyalloc): Change member names
4609         to be the same as the stack names.
4610         (yyparse): yyptr is now union yyalloc *, not char *.
4611         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4612         and may generate better code on some machines.
4613         (yystpcpy): Use prototype if __STDC__ is defined, not just
4614         if __cplusplus is defined.
4615
4616 2001-11-30  Akim Demaille  <akim@epita.fr>
4617
4618         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4619         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4620         Gettext doesn't compile cleanly, and dies with -Werror.
4621         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4622         Include WARNING_CFLAGS here.
4623         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4624         before being defined.
4625
4626 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4627
4628         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4629         First arg is int, not unsigned.
4630         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4631         (SIZE_MAX, UINT_MAX): New macros.
4632         (quotearg_n_options): Abort if N is negative.
4633         Avoid overflow check on hosts where size_t is 64 bits and int
4634         is 32 bits, as overflow is impossible there.
4635         Fix off-by-one typo that caused unnecessary reallocation.
4636
4637 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4638
4639         Name space cleanup in generated parser.
4640
4641         * doc/bison.texinfo (Bison Parser): Discuss system headers
4642         and their effect on the user name space.
4643
4644         * src/bison.simple:
4645         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4646         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4647         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4648
4649         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4650         on user names when possible.
4651
4652         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4653         Simplify test for whather <alloca.h> exists.
4654
4655         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4656
4657         (<stdio.h>): Include if YYDEBUG.
4658
4659         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4660         ! defined (yyoverflow) && ! defined (yymemcpy).
4661
4662         (yymemcpy, yyparse): Rename local variables as needed so that
4663         they all begin with 'yy'.
4664
4665         (yystrlen, yystpcpy): New functions.
4666
4667         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4668         All uses changed.
4669
4670         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4671         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4672         and YYSTACK_FREE instead of malloc and free.
4673
4674 2001-11-30  Akim Demaille  <akim@epita.fr>
4675
4676         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4677         before their first uses.

4685
4686         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4687         if body instead of `;' to pacify GCC's warnings.
4688
4689 2001-11-30  Akim Demaille  <akim@epita.fr>
4690
4691         Instead of mapping the LHS of unused rules to -1, keep the LHS
4692         valid, but flag the rules as invalid.
4693
4694         * src/gram.h (rule_t): `useful' is a new member.
4695         * src/print.c (print_grammar): Adjust.

4709
4710         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4711         useless nonterminals, move them at the end of the symbol arrays.
4712         (reduce_output): Adjust.
4713         * tests/reduce.at (Useless Nonterminals): Adjust.
4714
4715 2001-11-30  Akim Demaille  <akim@epita.fr>

4718         (nonterminals_reduce): New, extracted from...
4719         (reduce_grammar_tables): here.
4720         (reduce_grammar): Call nonterminals_reduce.
4721
4722 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4723
4724         * src/bison.simple (YYSTACK_REALLOC): Remove.
4725         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4726         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4727         New macros.
4728         (union yyalloc): New type.
4729         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4730         an arbitrary restriction on hosts where size_t is wider than int.
4731
4732         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4733         a parser stack overflow.  Allocate just one block of memory for all
4734         three stacks, instead of allocating three blocks; this typically is
4735         faster and reduces fragmentation.
4736
4737         Do not limit the number of items in the stack to a value that fits
4738         in 'int', as this is an arbitrary limit on hosts with 64-bit
4739         size_t and 32-bit int.
4740
4741 2001-11-29  Marc Autret  <autret_m@epita.fr>
4742
4743         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4744         of defining YYERROR_VERBOSE.

4747 2001-11-28  Marc Autret  <autret_m@epita.fr>

4758         (prepare): Echo name modification.
4759         * src/getargs.h: Clean its extern declaration.
4760         * src/getargs.c (error_verbose_flag): Remove.
4761         (getargs): Remove case 'e'.
4762         * src/options.c (option_table): 'error-verbose' is now seen as simple
4763         percent option.
4764         Include output.h.
4765
4766         * src/reader.c (read_declarations): Remove case tok_include.

4769         * src/options.c (option_table): 'include' is now a simple command line
4770         option.
4771
4772 2001-11-28  Marc Autret  <autret_m@epita.fr>
4773
4774         * src/bison.simple: Adjust muscle names.
4775         * src/muscle_tab.c (muscle_init): Also rename the muscles.
4776         * src/output.c (prepare): s/_/-/ for the muscles names.
4777         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
4778
4779 2001-11-28  Marc Autret  <autret_m@epita.fr>

4788
4789 2001-11-28  Akim Demaille  <akim@epita.fr>
4790
4791         * src/closure.c (closure): `b' and `ruleno' denote the same value:
4792         keep ruleno only.
4793
4794 2001-11-28  Akim Demaille  <akim@epita.fr>
4795
4796         * src/closure.c (closure): Instead of looping over word in array
4797         then bits in words, loop over bits in array.
4798
4799 2001-11-28  Akim Demaille  <akim@epita.fr>
4800
4801         * src/closure.c (closure): No longer optimize the special case
4802         where all the bits of `ruleset[r]' are set to 0, to make the code
4803         clearer.
4804
4805 2001-11-28  Akim Demaille  <akim@epita.fr>
4806
4807         * src/closure.c (closure): `r' and `c' are new variables, used to
4808         de-obfuscate accesses to RULESET and CORE.

4821         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
4822         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

6206         with something new. Skeletons are now processed character by character

6740         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it

6742         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6743         cast the value to (void *): assigning a `foo *' to a `void *'

6959 2000-10-02  Akim Demaille  <akim@epita.fr>
6960
6961         * src/derives.c, src/print.c, src/reduce.c: To ease the
6962         translation, move some `\n' out of the translated strings.
6963
6964 2000-10-02  Akim Demaille  <akim@epita.fr>
6965
6966         The location tracking mechanism is precious for parse error
6967         messages.  Nevertheless, it is enabled only when `@n' is used in
6968         the grammar, which is a different issue (you can use it in error
6969         message, but not in the grammar per se).  Therefore, there should
6970         be another means to enable it.
6971
6972         * src/getargs.c (getargs): Support `--locations'.
6973         (usage): Report it.
6974         * src/getargs.h (locationsflag): Export it.
6975         * src/lex.c (percent_table): Support `%locations'.
6976         * src/reader.c (yylsp_needed): Remove this variable, now replaced
6977         with `locationsflag'.
6978         * doc/bison.texinfo: Document `--locations' and `%locations'.
6979         Sort the options.
6980         * tests/calc.m4: Test it.
6981
6982         For regularity of the names, replace each
6983         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6984         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6985         In addition replace each `flag' with `_flag'.
6986
6987 2000-10-02  Akim Demaille  <akim@epita.fr>
6988
6989         Also test parse error messages, including with YYERROR_VERBOSE.
6990
6991         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6992         associative).
6993         Use it to check the computations.
6994         Use it to check `nonassoc' is honored.
6995         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6996         `--yyerror-verbose'.
6997         (_AT_CHECK_CALC): Adjust to this option.
6998         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6999
7000 2000-10-02  Akim Demaille  <akim@epita.fr>
7001
7002         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
7003         the latter demonstrates a flaw in the handling of non debugging
7004         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7005         was used in order to simplify:
7006
7007         #if YYDEBUG
7008         if (yydebug)
7009         {
7010         ...
7011         }
7012         #endif
7013
7014         into
7015
7016         if (yydebug)
7017         {
7018         ...
7019         }
7020
7021         unfortunately this leads to a CPP conflict when
7022         `--name-prefix=foo' is used since it produces `#define yydebug
7023         foodebug'.
7024
7025         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7026         (YYDPRINTF): New macro.
7027         Spread its use.
7028         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7029         the bison options.
7030         Also test `--verbose', `--defines' and `--name-prefix'.
7031
7032 2000-10-02  Akim Demaille  <akim@epita.fr>
7033
7034         Improve the readability of the produced parsers.
7035
7036         * src/bison.s1: Formatting changes.
7037         Improve the comment related to the `$' mark.
7038         (yydefault): Don't fall through to `yyresume': `goto' there.
7039         * src/output.c (output_parser): When the `$' is met, skip the end
7040         of its line.
7041         New variable, `number_of_dollar_signs', to check there's exactly
7042         one `$' in the parser skeleton.
7043
7044 2000-10-02  Akim Demaille  <akim@epita.fr>
7045
7046         * lib/xstrdup.c: New file, from the fileutils.
7047         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7048         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7049         instead of strlen + xmalloc + strcpy.
7050         * src/symtab.c (copys): Remove, use xstrdup instead.
7051
7052 2000-10-02  Akim Demaille  <akim@epita.fr>
7053
7054         * src/gram.h (associativity): New enum type which replaces the
7055         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7056         `right_assoc', `left_assoc' and `non_assoc'.
7057         Adjust all dependencies.
7058         * src/reader.c: Formatting changes.
7059         (LTYPESTR): Don't define it, use it as a literal in
7060         `reader_output_yylsp'.
7061         * src/symtab.h (symbol_class): New enum type which replaces the
7062         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7063         `sunknown', `stoken and `snterm'.
7064
7065 2000-10-02  Akim Demaille  <akim@epita.fr>
7066
7067         * src/getargs.c (fixed_outfiles): Rename as...
7068         (yaccflag): for consistency and accuracy.
7069         Adjust dependencies.
7070
7071 2000-10-02  Akim Demaille  <akim@epita.fr>
7072
7073         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7074         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
7075         difficult and introduced a lot of core dump.  It turns out that
7076         Bison used an implementation of `xmalloc' based on `calloc', and
7077         at various places it does depend upon the initialization to 0.  I
7078         have not tried to isolate the pertinent places, and all the former
7079         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
7080         someone should address this issue.
7081
7082         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7083         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7084         files.
7085         Adjust dependencies.
7086         * src/warshall.h: New file.
7087         Propagate.
7088
7089 2000-10-02  Akim Demaille  <akim@epita.fr>
7090
7091         Various anti-`extern in *.c' changes.
7092
7093         * src/system.h: Include `assert.h'.
7094
7095 2000-10-02  Akim Demaille  <akim@epita.fr>
7096
7097         * src/state.h (nstates, final_state, first_state, first_shift)
7098         (first_reduction): Move their exportation from here...
7099         * src/LR0.h: to here.
7100         Adjust dependencies.
7101         * src/getargs.c (statisticsflag): New variable.

7115         Propagate its use.
7116         * src/print.c: Formatting and ordering changes.
7117         (verbose, terse): Replace with...

7151         Propagate its use.
7152

7154
7155         * src/reader.h: New file.

7170
7171         * src/lalr.h: New file.

7174
7175 2000-10-02  Akim Demaille  <akim@epita.fr>
7176
7177         * src/output.c (token_actions): Introduce a temporary array,
7178         YYDEFACT, that makes it possible for this function to use
7179         output_short_table.
7180
7181 2000-10-02  Akim Demaille  <akim@epita.fr>
7182
7183         `user_toknums' is output as a `short[]' in `output.c', while it is
7184         defined as a `int[]' in `reader.c'.  For consistency with the
7185         other output tables, `user_toknums' is now defined as a table of
7186         shorts.
7187
7188         * src/reader.c (user_toknums): Be a short table instead of an int
7189         table.

7198 2000-10-02  Akim Demaille  <akim@epita.fr>
7199
7200         * src/output.c (output): Topological sort of the functions, in
7201         order to get rid of the `static' prototypes.
7202         No longer use `register'.
7203         * src/output.h: New file.
7204         Propagate its inclusion in files explicitly prototyping functions
7205         from output.c.

7212

7214         * src/closure.c: Formatting changes, topological sort over the
7215         functions, use of closure.h.
7216         (initialize_closure, finalize_closure):  Rename as...
7217         (new_closure, free_closure): these.  Adjust dependencies.
7218         * src/LR0.c: Formatting changes, topological sort, use of
7219         cloture.h.
7220         (initialize_states): Rename as...

7224 2000-09-20  Akim Demaille  <akim@epita.fr>
7225
7226         * src/acconfig.h: Don't protect config.h against multiple
7227         inclusion.
7228         Don't define PARAMS.
7229         * src/system.h: Define PARAMS.
7230         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7231         purpose of config.h.  system.h must not try to fix wrong
7232         definitions in config.h.
7233
7234 2000-09-20  Akim Demaille  <akim@epita.fr>

7246         Use these macros to test bison with options `', `--raw',
7247         `--debug', `--yacc', `--yacc --debug'.
7248

7250
7251         * src/output.c: Formatting changes.

7256         * src/getargs.h: New file.
7257         Let all `extern' declarations about getargs.c be replaced with

7271 2000-09-18  Akim Demaille  <akim@epita.fr>
7272
7273         * configure.in: Append WARNING_CFLAGS to CFLAGS.
7274         * src/Makefile.am (INCLUDES): Don't.
7275         Be ready to fetch headers in lib/.
7276
7277 2000-09-18  Akim Demaille  <akim@epita.fr>
7278

7310         (VERSION_STRING): Remove.
7311
7312 2000-04-14  Akim Demaille  <akim@epita.fr>
7313
7314         * src/reader.c (copy_comment2): New function, same as former
7315         `copy_comment', but outputs into two FILE *.
7316         (copy_comment): Use it.
7317         (parse_union_decl): Use it.
7318         (get_type, parse_start_decl): Use the same `invalid' message.

7394         the file name, not the whole `#line LINE FILE'.
7395
7396 2000-03-17  Akim Demaille  <akim@epita.fr>
7397
7398         On syntax errors, report the token on which we choked.
7399

7420         copy_comment.  Removed now unused `match', `ended',
7421         `cplus_comment'.
7422         (copy_comment, copy_string): Moved, to be visible from
7423         copy_definition.

7449
7450         Change the handling of @s so that they behave exactly like $s.
7451         There is now a pseudo variable @$ (readble and writable), location
7452         of the lhs of the rule (by default ranging from the location of
7453         the first symbol of the rhs, to the location of the last symbol,
7454         or, if the rhs is empty, YYLLOC).
7455
7456         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7457         yyval.
7458         (yyparse): When providing a default semantic action, provide a
7459         default location action.
7460         (after the $): No longer change `*YYLSP', just stack YYLOC the
7461         same way you stack YYVAL.
7462         * src/reader.c (read_declarations): Use warns.
7463         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7464         (copy_action, case '@'): Likewise.
7465         Use a standard error message, to save useless work from
7466         translators.
7467
7468 2000-03-17  Akim Demaille  <akim@epita.fr>
7469

7487
7488         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7489         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7490         One `#if YYDEBUG' remains, since it uses variables which are
7491         defined only if `YYDEBUG != 0'.
7492
7493 2000-03-16  Akim Demaille  <akim@epita.fr>
7494
7495         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

7517         handled via src/Makefile.am.

7519         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
7520         autoheader.

7525         the proper line number and file name.
7526         (DEFS): Propagate the location of bison library files and of the
7527         locale files.
7528         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7529         builddir.
7530         * acinclude.m4: Remove, replaced by the directory m4.
7531         * m4/Makefile.am (EXTRA_DIST): New variable.
7532         * m4/gettext.m4: New file, from the fileutils.

8218         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
8219         major changes to files.c.
8220         (lex) Retain in the incoming stream a character following
8221         an incorrect '/'.
8222         (skip_white_space, lex):  Revised most error messages
8223         and changed fatal to warn to avoid aborting.
