  28
  29         Portability fixes for bitsets; this also avoids several GCC
  30         warnings.
  31
  32         * lib/abitset.c: Include <stddef.h>, for offsetof.
  33         * lib/lbitset.c: Likewise.
  34
  35         * lib/abitset.c (abitset_bytes): Return a size that is aligned
  36         properly for vectors of objects.  Do not assume that adding a
  37         header size to a multiple of a word size yields a value that is
  38         properly aligned for the whole union.
  39         * lib/bitsetv.c (bitsetv_alloc): Likewise.
  40
  41         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
  42         unique names for structures.
  43         * lib/ebitset.c (ebitset_bytes): Likewise.
  44         * lib/lbitset.c (lbitset_bytes): Likewise.
  45
  46         * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
  47         abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
  48         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
  49         abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
  50         abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
  51         abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
  52         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
  53         to improve the type-checking that GCC can do.
  54         * lib/bitset.c (bitset_op4_cmp): Likewise.
  55         * lib/bitset_stats.c (bitset_stats_count,
  56         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
  57         bitset_stats_copy, bitset_stats_disjoint_p,
  58         bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
  59         bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
  60         bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
  61         bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
  62         bitset_stats_and_or_cmp, bitset_stats_andn_or,
  63         bitset_stats_andn_or_cmp, bitset_stats_or_and,
  64         bitset_stats_or_and_cmp): Likewise.
  65         * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
  66         lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
  67         lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
  68         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
  69
  70         * lib/abitset.h: Include bitset.h, not bbitset.h.
  71         * lib/ebitset.h: Likewise.
  72         * lib/lbitset.h: Likewise.
  73
  74         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
  75         All instances of parameters of type enum bitset_opts are now of
  76         type enum_bitset_opts, to conform to the C Standard, and similarly
  77         for enum_bitset_type.
  78         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
  79         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
  80
  81         Do not use "struct bitset_struct" to mean different things in
  82         different modules.  Not only is this confusing, it violates
  83         the C Standard, which requires that structure types in different
  84         modules must be compatible if one is to be passed to the other.
  85         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
  86         All instances of "struct bitset_struct *" replaced with "bitset".
  87         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
  88         (union bitset_union, struct abitset_struct, struct ebitset_struct,
  89         struct lbitset_struct, struct bitset_stats_struct): New types.
  90         All uses of struct bitset_struct changed to union bitset_union,
  91         etc.
  92         * lib/abitset.c (struct abitset_struct, abitset,
  93         struct bitset_struct): Remove.
  94         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
  95         struct bitset_struct): Remove.
  96         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
  97         bitset_struct): Remove.
  98         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
  99         Likewise.
 100
 101         Do not call a function of type T using a call that assumes the
 102         function is of a different type U.  Standard C requires that a
 103         function must be called with a type that is compatible with its
 104         definition.
 105         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 106         New decls.
 107         * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 108         New functions.
 109         * lib/ebitset.c (PFV): Remove.
 110         * lib/lbitset.c (PFV): Likewise.
 111         * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
 112         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
 113         decls.
 114         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
 115         (ebitset_vtable): Use them.
 116         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
 117         lbitset_xor): New functions.
 118         (lbitset_vtable): Use them.
 119
 120         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
 121         Declare.
 122
 123         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
 124         GCC warning.
 125         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
 126         Use offsetof, for simplicity.
 127
 128 2002-10-06  Paul Eggert  <eggert@twinsun.com>
 129
 130         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
 131         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
 132         <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
 133         which was inadvertently undone by the 2002-09-30 patch.
 134         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
 135         the same width as int.
 136
 137 2002-10-04  Paul Eggert  <eggert@twinsun.com>
 138
 139         Version 1.50.
 140
 141         * configure.ac (AC_INIT), NEWS: Increment version number.
 142
 143         * doc/bison.texinfo: Minor spelling, grammar, and white space
 144         fixes.
 145         (Symbols): Mention that any negative value returned from yylex
 146         signifies end-of-input.  Warn about negative chars.  Mention
 147         the portable Standard C character set.
 148
 149         The GNU coding standard says CFLAGS and YFLAGS are reserved
 150         for the installer to set.
 151         * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
 152         * src/Makefile.am (AM_CFLAGS): Likewise.
 153         (AM_YFLAGS): Renamed from YFLAGS.
 154
 155         Fix some MAX and MIN problems.
 156         * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
 157         * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
 158         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
 159         * src/reader.c (reader): Use it.
 160
 161         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
 162         POSIX 1003.1-2001 has removed fgrep.
 163
 164 2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
 165
 166         * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
 167         interpreted as signed.
 168         * lib/ebitset.c (ebitset_list): Fix bug.
 169
 170 2002-10-01  Paul Eggert  <eggert@twinsun.com>
 171
 172         More fixes for 64-bit hosts and large bitsets.
 173
 174         * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
 175         abitset_size, abitset_list, abitset_list_reverse, abitset_list):
 176         Use bitset_bindex, not int or unsigned int or size_t, to count bits.

 178         struct bitset_vtable.list, struct bitset_vtable.list_reverse,
 179         bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,
 180         bitset_count_): Likewise.
 181         * lib/bitset.h (bitset_iterator.num, bitset_iterator.i,
 182         bitset_first, bitset_last): Likewise.
 183         * lib/bitset_stats.c (bitset_stats_size, bitset_stats_list,
 184         bitset_stats_list_reverse, bitset_stats_size,
 185         bitset_stats_count, bitset_stats_list, bitset_stat_list_reverse):
 186         Likewise.
 187         * lib/bitsetv-print.c (bitsetv_matrix_dump): Likewise.
 188         * lib/bitsetv.c (bitsetv_alloc, bitsetv_create, bitsetv_free,
 189         bitsetv_zero, bitsetv_ones, bitsetv_transitive_closure,

 210
 211         * lib/abitset.c (abitset_empty_p, abitset_not, abitset_equal_p,
 212         abitset_subset_p, abitset_disjoint_p, abitset_and,
 213         abitset_and_cmp, abitset_andn, abitset_andn_cmp, abitset_or,

 233         * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
 234         BITSET_SIZE_MAX): New macros.
 235         (BITSET_INDEX_MAX): Remove.  It wasn't right, since it assumed that
 236         sizeof (bitset_word) == sizeof (bitset_windex).  All uses changed
 237         to BITSET_WINDEX_MAX.
 238
 239         * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
 240         bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
 241         since we now return the bitset_bindex type (not int).

 246
 247         * lib/lbitset.c (lbitset_elt_find): Simplify windex calculation
 248         and avoid cast to unsigned.

 340
 341         * doc/bison.texinfo (Conditions): Make explicit that the GPL

 351         * data/lalr1.cc (struct yyltype): Don't define it, since we use
 352         LocationType.
 353         (b4_ltype): Default to yy::Location from location.hh.
 354
 355 2002-09-04  Jim Meyering  <jim@meyering.net>
 356
 357         * data/yacc.c: Guard the declaration of yytoknum also with
 358         `#ifdef YYPRINT', so it is declared only when used.
 359
 360 2002-09-04  Akim Demaille  <akim@epita.fr>
 361
 362         * configure.in: Rename as...

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

 390         (yyreportParseError): Use size_t for yysize.
 391         (yy_yypstack): No longer nested inside yypstates, as nested
 392         functions are not portable.  Do not assume size_t is the
 393         same width as int.
 394         (yypstates): Do not assume that ptrdiff_t is the same width
 395         as int, and similarly for yyposn and YYINDEX.
 396
 397         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 398
 399         * lib/Makefile.am (INCLUDES): Do not include from the intl
 400         directory, which has been removed.
 401         * src/Makefile.am (INCLUDES): Likewise.

 409
 410         * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):

 422         portability to one's complement hosts!).
 423         * lib/ebitset.c (ebitset_op1): Likewise.
 424         * lib/lbitset.c (lbitset_op1): Likewise.
 425

 431         lib/gettext.h: Sync with diffutils.
 432

 434         lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
 435
 436         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 437         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 438         check for void *.
 439
 440         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 441         size_t; the old version tried to do this but casted improperly.
 442         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 443         (bitset_test): Now returns int, not unsigned long.

 447         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 448         name locals "index", as it generates unnecessary warnings on some
 449         hosts that have an "index" function.
 450
 451         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 452         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
 453         they need translation.

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

 469         * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
 470
 471         * po/LINGUAS: Add pt_BR.
 472         * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
 473         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 474         lib/timevar.c.
 475         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 476         manual recommends.
 477         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 478
 479         * src/complain.c (strerror_r): Remove decl; not needed.
 480         (strerror): Use same pattern as ../lib/error.c.
 481
 482         * src/files.c, src/files.h (compute_header_macro): Remove; unused.

 485
 486         * src/main.c (main): Cast result of bindtextdomain and textdomain
 487         to void, to avoid a GCC warning when --disable-nls is in effect.
 488
 489         * src/scan-gram.l: Use strings rather than escapes when possible,
 490         to minimize the number of warnings from xgettext.
 491         (handle_action_dollar, handle_action_at): Don't use isdigit,
 492         as it mishandles negative chars and it may not work as expected
 493         outside the C locale.
 494
 495         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 496         this is a GCC extension and is not portable to other compilers.
 497
 498         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 499         Do not include <ctype.h>; no longer needed.
 500         Do not include <malloc.h>; no longer needed (and generates
 501         warnings on OpenBSD 3.0).
 502
 503         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
 504         it's not portable.
 505
 506         * tests/regression.at: Do not use 'cc -c input.c -o input';
 507         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
 508
 509         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
 510         exit status as failure, not just exit status 1.  Sun C exits
 511         with status 2 sometimes.
 512
 513         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
 514         Use it for the two large tests.
 515
 516 2002-08-02  Akim Demaille  <akim@epita.fr>
 517
 518         * src/conflicts.c (conflicts_output): Don't output rules never
 519         reduced here, since anyway that computation doesn't work.
 520         * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
 521         (rule_useless_p, rule_never_reduced_p): New.

 527         reduced to...
 528         (token_actions): here.
 529         * src/main.c (main): Make the parser before making the report, so
 530         that rules never reduced are computed.
 531         Call grammar_rules_never_reduced_report.
 532         * src/print.c (print_results): Report rules never reduced.
 533         * tests/conflicts.at, tests/reduce.at: Adjust.
 534
 535 2002-08-01  Akim Demaille  <akim@epita.fr>
 536
 537         Instead of attaching lookaheads and duplicating the rules being
 538         reduced by a state, attach the lookaheads to the reductions.
 539
 540         * src/state.h (state_t): Remove the `lookaheads',
 541         `lookaheads_rule' member.
 542         (reductions_t): Add a `lookaheads' member.

 544         * src/state.c (reductions_new): Initialize the lookaheads member
 545         to 0.
 546         (state_rule_lookaheads_print): Adjust.
 547         * src/state.h, src/state.c (state_reductions_find): New.

 554         (initialize_LA): this.
 555         (lalr_free): Adjust.
 556         * src/main.c (main): Don't free nullable and derives too early: it
 557         is used by --verbose.
 558         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
 559
 560 2002-08-01  Akim Demaille  <akim@epita.fr>
 561
 562         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
 563         `rule_number_t**'.
 564         (set_derives, free_derives): Rename as...

 571         pointers, instead of their numbers.
 572         * src/main.c (main): Call nullable_free, and derives_free earlier,
 573         as they were lo longer used.
 574
 575 2002-08-01  Akim Demaille  <akim@epita.fr>
 576
 577         * lib/timevar.c (get_time): Include children time.
 578         * src/lalr.h (LA, LArule): Don't export them: used with the
 579         state_t.
 580         * src/lalr.c (LA, LArule): Static.
 581         * src/lalr.h, src/lalr.c (lalr_free): New.

 583         * src/tables.c (pack_vector): Check whether loc is >= to the
 584         table_size, not >.
 585         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
 586         (tables_generate): do it, since that's also it which allocates
 587         them.
 588         Don't free LA and LArule, main does.
 589
 590 2002-07-31  Akim Demaille  <akim@epita.fr>

 673
 674         Report rules which are never reduced by the parser: those hidden
 675         by conflicts.
 676
 677         * src/LR0.c (save_reductions): Don't make the final state too
 678         different: save its reduction (accept) instead of having a state
 679         without any action (no shift or goto, no reduce).
 680         Note: the final state is now a ``regular'' state, i.e., the
 681         parsers now contain `reduce 0' as default reduction.
 682         Nevertheless, since they decide to `accept' when yystate =
 683         final_state, they still will not reduce rule 0.

 716         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
 717         Adjust.
 718
 719 2002-07-29  Akim Demaille  <akim@epita.fr>

 732         token_translations instead of `0'.
 733         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
 734         visible here.
 735         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
 736         for the time being: %locations ought to provide it to yyerror.
 737
 738 2002-07-25  Akim Demaille  <akim@epita.fr>
 739
 740         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1809         grammar.
1810         Use more modest sizes, as for the time being the parser does not

1812         of memory.
1813
1814         * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the

1825         eccentricities.

1900
1901         Remove `%thong' support as it is undocumented, unused, duplicates
1902         `%token's job, and creates useless e-mail traffic with people who

2371         * src/reduce.c (dump_grammar): Move to...
2372         * src/gram.h, src/gram.c (grammar_dump): here.

2375
2376 2002-04-22  Akim Demaille  <akim@epita.fr>
2377
2378         * src/output.c (table_size, table_grow): New.
2379         (MAXTABLE): Remove, replace uses with table_size.
2380         (pack_vector): Instead of dying when the table is too big, grow it.
2381
2382 2002-04-22  Akim Demaille  <akim@epita.fr>
2383
2384         * data/bison.simple (yyr1): Its type is that of a token number.
2385         * data/bison.c++ (r1_): Likewise.

2389
2390         * src/reader.c (token_translations_init): 256 is now the default
2391         value for the error token, i.e., it will be assigned another
2392         number if the user assigned 256 to one of her tokens.
2393         (reader): Don't force 256 to error.
2394         * doc/bison.texinfo (Symbols): Adjust.
2395         * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
2396         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
2397         etc. instead of 10, 20, 30 (which was used to `jump' over error
2398         (256) and undefined (2)).
2399
2400 2002-04-22  Akim Demaille  <akim@epita.fr>
2401
2402         Propagate more token_number_t.

2405         (item_number_as_token_number): New.
2406         * src/output.c (GENERATE_OUTPUT_TABLE): New.
2407         Use it to create output_item_number_table and
2408         output_token_number_table.
2409         * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,

2416         * src/output.h, src/output.c (get_lines_number): Remove.
2417
2418 2002-04-19  Akim Demaille  <akim@epita.fr>

2420         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
2421         as Lex/Flex'.
2422         (Debugging): More details about enabling the debugging features.
2423         (Table of Symbols): Describe $$, $n, @$, and @n.
2424         Suggested by Tim Josling.

2427
2428         * doc/bison.texinfo: Remove the uses of the obsolete @refill.

2431
2432         * src/system.h: Rely on HAVE_LIMITS_H.
2433         Suggested by Paul Eggert.
2434
2435 2002-04-09  Akim Demaille  <akim@epita.fr>
2436
2437         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2438         full stderr, and strip it according to the bison options, instead
2439         of composing the error message from different bits.
2440         This makes it easier to check for several error messages.
2441         Adjust all the invocations.
2442         Add an invocation exercising the error token.
2443         Add an invocation demonstrating a stupid error message.
2444         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
2445         Adjust the tests.
2446         Error message are for stderr, not stdout.
2447
2448 2002-04-09  Akim Demaille  <akim@epita.fr>
2449
2450         * src/gram.h, src/gram.c (error_token_number): Remove, use
2451         errtoken->number.
2452         * src/reader.c (reader): Don't specify the user token number (2)
2453         for $undefined, as it uselessly prevents using it.
2454         * src/gram.h (token_number_t): Move to...
2455         * src/symtab.h: here.
2456         (state_t.number): Is a token_number_t.
2457         * src/print.c, src/reader.c: Use undeftoken->number instead of
2458         hard coded 2.
2459         (Even though this 2 is not the same as above: the number of the
2460         undeftoken remains being 2, it is its user token number which
2461         might not be 2).
2462         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2463         `user_token_number_max'.
2464         Output `undef_token_number'.
2465         * data/bison.simple, data/bison.c++: Use them.
2466         Be sure to map invalid yylex return values to
2467         `undef_token_number'.  This saves us from gratuitous SEGV.
2468
2469         * tests/conflicts.at (Solved SR Conflicts)
2470         (Unresolved SR Conflicts): Adjust.
2471         * tests/regression.at (Web2c Actions): Adjust.

2474
2475         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
2476         Adding #line.
2477         Remove the duplicate `typedefs'.
2478         (RhsNumberType): Fix the declaration and various other typos.
2479         Use __ofile__.
2480         * data/bison.simple: Use __ofile__.
2481         * src/scan-skel.l: Handle __ofile__.
2482

2484
2485         * src/gram.h (item_number_t): New, the type of item numbers in
2486         RITEM.  Note that it must be able to code symbol numbers as
2487         positive number, and the negation of rule numbers as negative
2488         numbers.
2489         Adjust all dependencies (pretty many).
2490         * src/reduce.c (rule): Remove this `short *' pointer: use
2491         item_number_t.
2492         * src/system.h (MINSHORT, MAXSHORT): Remove.
2493         Include `limits.h'.
2494         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2495         (shortcpy): Remove.
2496         (MAXTABLE): Move to...
2497         * src/output.c (MAXTABLE): here.
2498         (prepare_rules): Use output_int_table to output rhs.
2499         * data/bison.simple, data/bison.c++: Adjust.
2500         * tests/torture.at (Big triangle): Move the limit from 254 to
2501         500.
2502         * tests/regression.at (Web2c Actions): Ajust.
2503
2504         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2505         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2506         passes, but produces negative #line number, once fixed, GCC is
2507         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2508         C), it passes.
2509         * src/state.h (state_h): Code input lines on ints, not shorts.
2510
2511 2002-04-08  Akim Demaille  <akim@epita.fr>
2512
2513         * src/reduce.c (reduce_grammar): First reduce the nonterminals,

2526         New.
2527         Use them to define yy_token_number_type/TokenNumberType.
2528         Use this type for yytranslate.
2529         * tests/torture.at (Big triangle): Push the limit from 124 to

2637 2002-04-07  Akim Demaille  <akim@epita.fr>
2638
2639         Be sure never to walk through RITEMS, but use only data related to
2640         the rules themselves. RITEMS should be banished.
2641
2642         * src/output.c (output_token_translations): Rename as...
2643         (prepare_tokens): this.
2644         In addition to `translate', prepare the muscles `tname' and

2660         Adjust to initialize first_state and last_state if needed.
2661         Be sure to distinguish the initial from the final state.
2662         (new_states): Create the itemset of the initial state, and use
2663         new_state.
2664         * src/closure.c (closure): Now that the initial state has its
2665         items properly set, there is no need for a special case when
2666         creating `ruleset'.
2667
2668         As a result, now the rule 0, reducing to $axiom, is visible in the
2669         outputs.  Adjust the test suite.

3010         causing more problems than it was curing, since it didn't work
3011         properly on some nonstandard C++ compilers.  This can wait

3057         more consistent when naming methods and variables.  Put preprocessor
3058         directives around tables only needed for debugging.
3059
3060 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3061
3062         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
3063         C++ parsers.
3064         (yy::b4_name::parse): Use print_.
3065
3066 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3067
3068         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
3069
3070 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3071
3072         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
3073         C++ parsers.
3074         (yy::b4_name::parse): Build verbose error messages, and use error_.
3075
3076 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3077
3078         * data/bison.c++: Fix m4 quoting in comments.
3079
3080 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3081
3082         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
3083         not expanded by m4.
3084
3085 2002-02-05  Akim Demaille  <akim@epita.fr>
3086
3087         * data/bison.c++: Adjust to the M4 back end.
3088         More is certainly needed.
3089
3090 2002-02-05  Akim Demaille  <akim@epita.fr>
3091
3092         Give a try to M4 as a back end.
3093
3094         * lib/readpipe.c: New, from wdiff.
3095         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
3096         BISON_HAIRY.
3097         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
3098         specific values.  Now it is m4 that performs the lookup.
3099         * src/parse-skel.y: Remove.
3100         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
3101         * src/output.c (actions_output, guards_output)
3102         (token_definitions_output): No longer keeps track of the output
3103         line number, hence remove the second argument.
3104         (guards_output): Check against the guard member of a rule, not the
3105         action member.
3106         Adjust callers.
3107         (output_skeleton): Don't look for the skeleton location, let m4 do
3108         that.
3109         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
3110         file will be used.
3111         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3112         (prepare): Given that for the time being changesyntax is not
3113         usable in M4, rename the muscles using `-' to `_'.
3114         Define `defines_flag', `output_parser_name' and `output_header_name'.
3115         * src/output.h (actions_output, guards_output)
3116         (token_definitions_output): Adjust prototypes.
3117         * src/scan-skel.l: Instead of scanning the skeletons, it now
3118         processes the output of m4: `__oline__' and `#output'.
3119         * data/bison.simple: Adjust to be used by M4(sugar).
3120         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3121         to date.
3122         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3123         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
3124         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
3125         shamelessly stolen from CVS Autoconf.
3126
3127 2002-02-05  Akim Demaille  <akim@epita.fr>
3128
3129         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
3130         * configure.in: Check for the declarations of free and malloc.
3131         * src/muscle_tab.c: Adjust.
3132
3133 2002-02-05  Akim Demaille  <akim@epita.fr>
3134
3135         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
3136         which have no values.
3137
3138 2002-02-05  Akim Demaille  <akim@epita.fr>
3139
3140         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
3141         * data/: here.
3142
3143 2002-01-29  Paul Eggert  <eggert@twinsun.com>
3144
3145         * src/bison.simple (YYSIZE_T): Do not define merely because
3146         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3147         On some platforms, <alloca.h> does not declare YYSTD (size_t).
3148
3149 2002-01-27  Akim Demaille  <akim@epita.fr>
3150
3151         Fix `%nonassoc and eof'.
3152
3153         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
3154         which were not properly copied!  Replace
3155         memcpy (res->errs, src->errs, src->nerrs);
3156         with
3157         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3158         !!!
3159         * tests/regression.at (%nonassoc and eof): Adjust to newest
3160         Autotest: `.' is not in the PATH.
3161
3162 2002-01-27  Akim Demaille  <akim@epita.fr>
3163
3164         * tests/sets.at (AT_EXTRACT_SETS): New.
3165         (Nullable): Use it.
3166         (Firsts): New.
3167
3168 2002-01-26  Akim Demaille  <akim@epita.fr>
3169
3170         * tests/actions.at, tests/calc.at, tests/headers.at,
3171         * tests/torture.at: Adjust to the newest Autotest which no longer
3172         forces `.' in the PATH.
3173
3174 2002-01-25  Akim Demaille  <akim@epita.fr>
3175
3176         * tests/regression.at (%nonassoc and eof): New.
3177         Suggested by Robert Anisko.
3178
3179 2002-01-24  Akim Demaille  <akim@epita.fr>
3180
3181         Bison dumps core when trying to complain about broken input files.
3182         Reported by Cris van Pelt.
3183
3184         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
3185         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
3186         into...
3187         (Invalid inputs): Strengthen: exercise parse_percent_token.
3188
3189 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
3190
3191         * src/Makefile.am: Add bison.c++.
3192         * src/bison.c++: New skeleton.
3193
3194 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
3195
3196         * po/it.po: New.
3197
3198 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
3199
3200         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
3201
3202 2002-01-20  Marc Autret  <marc@gnu.org>
3203
3204         * src/files.c (compute_output_file_names): Fix
3205
3206 2002-01-20  Marc Autret  <marc@gnu.org>
3207
3208         * tests/output.at: New test.
3209         * src/files.c (compute_base_names): Don't map extensions when
3210         the YACC flag is set, use defaults.
3211         Reported by Evgeny Stambulchik.
3212
3213 2002-01-20  Marc Autret  <marc@gnu.org>
3214
3215         * src/system.h: Need to define __attribute__ away for non-GCC
3216         compilers as well (i.e. the vendor C compiler).
3217         Suggested by Albert Chin-A-Young.
3218
3219 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
3220
3221         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3222         canonical definition.
3223         * src/system.h: Use the canonical definition for PARAMS (avoids
3224         a conflict with the macro from lib/hash.h).
3225
3226 2002-01-11  Akim Demaille  <akim@epita.fr>
3227
3228         * configure.in: Use AC_FUNC_STRNLEN.
3229         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3230
3231 2002-01-09  Akim Demaille  <akim@epita.fr>
3232
3233         * src/files.c, src/files.h (output_infix): New.
3234         (tab_extension): Remove.
3235         (compute_base_names): Compute the former, drop the latter.
3236         * src/output.c (prepare): Insert the muscles `output-infix', and
3237         `output-suffix'.
3238         * src/parse-skel.y (string, string.1): New.
3239         (section.header): Use it.
3240         (section.yacc): Remove.
3241         (prefix): Remove too.
3242         * src/scan-skel.l: Adjust.
3243         * src/bison.simple, src/bison.hairy: Adjust.
3244
3245 2002-01-09  Akim Demaille  <akim@epita.fr>
3246
3247         * configure.in (WERROR_CFLAGS): Compute it.
3248         * src/Makefile.am (CFLAGS): Pass it.
3249         * tests/atlocal.in (CFLAGS): Idem.
3250         * src/files.c: Fix a few warnings.
3251         (get_extension_index): Remove, unused.
3252
3253 2002-01-08  Akim Demaille  <akim@epita.fr>
3254
3255         * src/getargs.c (AS_FILE_NAME): New.
3256         (getargs): Use it to convert DOSish file names.
3257         * src/files.c (base_name): Rename as full_base_name to avoid
3258         clashes with `base_name ()'.
3259         (filename_split): New.
3260         (compute_base_names): N-th rewrite, using filename_split.
3261
3262 2002-01-08  Akim Demaille  <akim@epita.fr>
3263
3264         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3265         New, stolen from the Fileutils 4.1.
3266         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3267         * configure.in: Check for the presence of memrchr, and of its
3268         prototype.
3269
3270 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3271
3272         * lib/hash.h (__P): Added definition for this macro.
3273         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3274         BUILT_SOURCES, to ensure they are generated first.
3275         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3276         %error-verbose to allow bootstrapping with bison 1.30x.
3277
3278 2002-01-06  Akim Demaille  <akim@epita.fr>
3279
3280         * src/reader.c (parse_braces): Don't fetch the next char, the
3281         convention is to fetch on entry.
3282         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3283         'switch' without a following semicolon.
3284         * tests/regression.at (braces parsing): New.
3285
3286 2002-01-06  Akim Demaille  <akim@epita.fr>
3287
3288         Bison is dead wrong in its RR conflict reports.
3289
3290         * tests/torture.at (GNU Cim Grammar): New.
3291         * src/conflicts.c (count_rr_conflicts): Fix.
3292
3293 2002-01-06  Akim Demaille  <akim@epita.fr>
3294
3295         Creating package.m4 from configure.ac causes too many problems.
3296
3297         * tests/Makefile.am (package.m4): Create it by hand,
3298         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3299
3300 2002-01-06  Akim Demaille  <akim@epita.fr>
3301
3302         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3303         skeleton.h.
3304
3305 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3306
3307         * doc/bison.texinfo (Debugging):
3308         Remove YYSTDERR; it's no longer defined or used.
3309         Also, s/cstdio.h/cstdio/.
3310
3311 2002-01-03  Akim Demaille  <akim@epita.fr>
3312
3313         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3314
3315 2002-01-03  Akim Demaille  <akim@epita.fr>
3316
3317         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3318         tracing code to --trace, wait for a better --trace option, with
3319         args.
3320
3321 2002-01-03  Akim Demaille  <akim@epita.fr>
3322
3323         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3324         The ISO C++ standard is extremely clear about it: stderr is
3325         considered a macro, not a regular symbol (see table 94 `Header
3326         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3327         Therefore std:: does not apply to it.  It still does with fprintf.
3328         Also, s/cstdio.h/cstdio/.
3329
3330 2002-01-03  Akim Demaille  <akim@epita.fr>
3331
3332         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3333         for non system headers.
3334
3335 2002-01-02  Akim Demaille  <akim@epita.fr>
3336
3337         Equip the skeleton chain with location tracking, runtime trace,
3338         pure parser and scanner.
3339
3340         * src/parse-skel.y: Request a pure parser, locations, and prefix
3341         renaming.
3342         (%union): Having several members with the same type does not help
3343         type mismatches, simplify.
3344         (YYPRINT, yyprint): New.
3345         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3346         (skel_error): this.
3347         Handle locations.
3348         * src/scan-skel.l: Adjust to these changes.
3349         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3350         (LOCATION_PRINT, skel_control_t): New.
3351
3352 2001-12-30  Akim Demaille  <akim@epita.fr>
3353
3354         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3355         replace `gb' with BLANKS.
3356         * src/scan-skel.l: Adjust.
3357
3358 2001-12-30  Akim Demaille  <akim@epita.fr>
3359
3360         * src/system.h: We don't need nor want bcopy.
3361         Throw away MS-DOS crap: we don't need getpid.
3362         * configure.in: We don't need strndup.  It was even causing
3363         problems: because Flex includes the headers *before* us,
3364         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3365         not visible.
3366         * lib/xstrndup.c: New.
3367         * src/scan-skel.l: Use it.
3368         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3369         * src/parse-skel.y: Use %directives instead of #defines.
3370
3371 2001-12-30  Akim Demaille  <akim@epita.fr>
3372
3373         * src/skeleton.h: New.
3374         * src/output.c (output_parser, output_master_parser): Remove, dead
3375         code.
3376         * src/output.h (get_lines_number, actions_output, guards_output)
3377         (token_definitions_output): Prototype them.
3378         * src/parse-skel.y: Add the license notice.
3379         Include output.h and skeleton.h.
3380         (process_skeleton): Returns void, and takes a single parameter.
3381         * src/scan-skel.l: Add the license notice.
3382         Include skeleton.h.
3383         Don't use %option yylineno: it seems that then Flex imagines
3384         REJECT has been used, and therefore it won't reallocate its
3385         buffers (which makes no other sense to me than a bug).  It results
3386         in warnings for `unused: yy_flex_realloc'.
3387
3388 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
3389
3390         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3391         (MUSCLE_INSERT_PREFIX): ...to there.
3392         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3393         (MUSCLE_INSERT_PREFIX): Move from here...
3394
3395         * src/bison.hairy: Add a section directive.  Put braces around muscle
3396         names.  This parser skeleton is still broken, but Bison should not
3397         choke on a bad muscle 'syntax'.
3398         * src/bison.simple: Add a section directive.  Put braces around muscle
3399         names.
3400
3401         * src/files.h (strsuffix, stringappend): Add declarations.
3402         (tab_extension): Add declaration.
3403         (short_base_name): Add declaration.
3404
3405         * src/files.c (strsuffix, stringappend): No longer static.  These
3406         functions are used in the skeleton parser.
3407         (tab_extension): New.
3408         (compute_base_names): Use the computations done in this function
3409         to guess if the generated parsers should have '.tab' in their
3410         names.
3411         (short_base_name): No longer static.
3412
3413         * src/output.c (output_skeleton): New.
3414         (output): Disable call to output_master_parser, and give a try to
3415         a new skeleton handling system.
3416         (guards_output, actions_output): No longer static.
3417         (token_definitions_output, get_lines_number): No longer static.
3418
3419         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3420
3421         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3422         parse-skel.y.
3423
3424         * src/parse-skel.y: New file.
3425         * src/scan-skel.l: New file.

3427 2001-12-29  Akim Demaille  <akim@epita.fr>
3428
3429         %name-prefix is broken.
3430
3431         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3432         Adjust all dependencies.
3433         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3434         %name-prefix.
3435
3436         Renaming yylval but not yylloc is not consistent.  Now we do.
3437
3438         * src/bison.simple: Prefix yylloc if used.
3439         * doc/bison.texinfo (Decl Summary): Document that.
3440
3441 2001-12-29  Akim Demaille  <akim@epita.fr>
3442
3443         * doc/bison.texinfo: Promote `%long-directive' over
3444         `%long_directive'.
3445         Remove all references to fixed-output-files, yacc is enough.
3446
3447 2001-12-29  Akim Demaille  <akim@epita.fr>
3448
3449         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3450         user prologue.  These are defaults.
3451         * tests/actions.at (Mid-rule actions): Make sure the user can
3452         define YYDEBUG and YYERROR_VERBOSE.
3453
3454 2001-12-29  Akim Demaille  <akim@epita.fr>
3455
3456         * src/output.c (header_output): Don't forget to export YYLTYPE and
3457         yylloc.
3458         * tests/headers.at (export YYLTYPE): New, make sure it does.
3459         * tests/regression.at (%union and --defines, Invalid CPP headers):
3460         Move to...
3461         * tests/headers.at: here.
3462
3463 2001-12-29  Akim Demaille  <akim@epita.fr>
3464
3465         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3466
3467 2001-12-29  Akim Demaille  <akim@epita.fr>
3468
3469         * tests/actions.at (Mid-rule actions): Output on a single line
3470         instead of several.
3471
3472 2001-12-29  Akim Demaille  <akim@epita.fr>
3473
3474         * doc/bison.texinfo: Formatting changes.
3475
3476 2001-12-29  Akim Demaille  <akim@epita.fr>
3477
3478         Don't store the token defs in a muscle, just be ready to output it
3479         on command.  Now possible via `symbols'.  Fixes a memory leak.
3480
3481         * src/output.c (token_definitions_output): New.
3482         (output_parser, header_output): Use it.
3483         * src/reader.c (symbols_save): Remove.
3484
3485 2001-12-29  Akim Demaille  <akim@epita.fr>
3486
3487         * src/bison.simple: Do not provide a default for YYSTYPE and
3488         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3489         default.
3490
3491 2001-12-29  Akim Demaille  <akim@epita.fr>
3492
3493         Mid-rule actions are simply... ignored!
3494
3495         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3496         the empty-rule associated to the dummy symbol, not to the host
3497         rule.
3498         * tests/actions.at (Mid-rule actions): New.
3499
3500 2001-12-29  Akim Demaille  <akim@epita.fr>
3501
3502         Memory leak.
3503
3504         * src/reader.c (reader): Free grammar.
3505
3506 2001-12-29  Akim Demaille  <akim@epita.fr>
3507
3508         Memory leak.
3509
3510         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3511         since it allocates it for each state, although only one is needed.
3512         (allocate_storage): Do it here.
3513
3514 2001-12-29  Akim Demaille  <akim@epita.fr>
3515
3516         * src/options.h, src/options.c (create_long_option_table): Rename
3517         as...
3518         (long_option_table_new): this, with a clearer prototype.
3519         (percent_table): Remove, unused,
3520         * src/getargs.c (getargs): Adjust.
3521
3522 2001-12-29  Akim Demaille  <akim@epita.fr>
3523
3524         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3525         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3526         as states.
3527
3528 2001-12-29  Akim Demaille  <akim@epita.fr>
3529
3530         * src/lalr.c (build_relations): Rename `states' as `states1'.
3531         Sorry, I don't understand exactly what it is, no better name...
3532
3533 2001-12-29  Akim Demaille  <akim@epita.fr>
3534
3535         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3536         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3537         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3538         as rules.
3539
3540 2001-12-29  Akim Demaille  <akim@epita.fr>
3541
3542         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3543         ago.
3544
3545 2001-12-29  Akim Demaille  <akim@epita.fr>
3546
3547         * src/reader.c, src/reader.h (user_toknums): Remove.
3548         Adjust all users to use symbols[i]->user_token_number.
3549
3550 2001-12-29  Akim Demaille  <akim@epita.fr>
3551
3552         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3553         Adjust all users to use symbols[i]->prec or ->assoc.
3554
3555 2001-12-29  Akim Demaille  <akim@epita.fr>
3556
3557         * src/reader.c, src/reader.h (tags): Remove.
3558         Adjust all users to use symbols[i]->tag.
3559
3560 2001-12-29  Akim Demaille  <akim@epita.fr>
3561
3562         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3563         and rule_table.
3564         * src/reader.c (packsymbols): Fill this table.
3565         Drop sprec.
3566         * src/conflicts.c (resolve_sr_conflict): Adjust.
3567         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3568         single table.
3569         Use symbols[i]->tag instead of tags[i].
3570
3571 2001-12-29  Akim Demaille  <akim@epita.fr>
3572
3573         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3574         In addition, put a comment in there, to replace...
3575         * tests/regression.at (%union and C comments): Remove.
3576
3577 2001-12-29  Akim Demaille  <akim@epita.fr>
3578
3579         * tests/regression.at (Web2c Actions): Blindly move the actual
3580         output as expected output.  The contents *seem* right to me, but I
3581         can't pretend reading perfectly parser tables...  Nonetheless, all
3582         the other tests pass correctly, the table look OK, even though the
3583         presence of `$axiom' is to be noted: AFAICS it is useless (but
3584         harmless).
3585
3586 2001-12-29  Akim Demaille  <akim@epita.fr>
3587
3588         * src/reader.c (readgram): Don't add the rule 0 if there were no
3589         rules read.  In other words, add it _after_ having performed
3590         grammar sanity checks.
3591         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3592
3593 2001-12-29  Akim Demaille  <akim@epita.fr>
3594
3595         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3596         visible, and some states have now a different number.
3597
3598 2001-12-29  Akim Demaille  <akim@epita.fr>
3599
3600         * src/reader.c (readgram): Bind the initial rule's lineno to that
3601         of the first rule.
3602         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3603         (Solved SR Conflicts): Adjust rule 0's line number.
3604
3605 2001-12-29  Akim Demaille  <akim@epita.fr>
3606
3607         Fix the `GAWK Grammar' failure.
3608
3609         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3610         the reductions of the first state which was mistakenly confused
3611         with the final state because precisely final_state was initialized
3612         to 0.
3613         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3614         now noticed by Bison.
3615         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3616         have a reduction on $default.
3617
3618 2001-12-29  Akim Demaille  <akim@epita.fr>
3619
3620         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3621         rule line numbers.
3622         * src/closure.c (print_closure): Likewise.
3623         * src/derives.c (print_derives): Likewise.
3624         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3625         now.
3626
3627 2001-12-29  Akim Demaille  <akim@epita.fr>
3628
3629         * src/lalr.c (lookaheads_print): New.
3630         (lalr): Call it when --trace-flag.
3631         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3632         are dumped.
3633
3634 2001-12-29  Akim Demaille  <akim@epita.fr>
3635
3636         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3637         when walking through ritem, even via rule->rhs.
3638         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3639         (useful_production, useless_nonterminals): Likewise.
3640         (reduce_grammar_tables): Likewise, plus update nritems.
3641         * src/nullable.c (set_nullable): Likewise.
3642         * src/lalr.c (build_relations): Likewise.
3643         * tests/sets.at (Nullable): Adjust.
3644         Fortunately, now, the $axiom is no longer nullable.
3645
3646 2001-12-29  Akim Demaille  <akim@epita.fr>
3647
3648         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3649         the 0-sentinel.
3650         * src/gram.c (ritem_longest_rhs): Likewise.
3651         * src/reduce.c (nonterminals_reduce): Likewise.
3652         * src/print_graph.c (print_graph): Likewise.
3653         * src/output.c (output_rule_data): Likewise.
3654         * src/nullable.c (set_nullable):  Likewise.
3655
3656 2001-12-29  Akim Demaille  <akim@epita.fr>
3657
3658         * src/output.c: Comment changes.
3659
3660 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3661
3662         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3663         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3664         Sparc, as they were causing more porting problems than the
3665         (minor) performance improvement was worth.
3666
3667         Also, catch up with 1.31's YYSTD.
3668
3669 2001-12-27  Akim Demaille  <akim@epita.fr>
3670
3671         * src/output.c (output_gram): Rely on nritems, not the
3672         0-sentinel.  See below.
3673         Use -1 as separator, not 0.
3674         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3675         Rely on -1 as separator in yyrhs, instead of 0.
3676         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3677         twice `Now at end of input', therefore there are two lines less to
3678         expect.
3679
3680 2001-12-27  Akim Demaille  <akim@epita.fr>
3681
3682         * tests/regression.at (Unresolved SR Conflicts):
3683         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3684         below.
3685
3686 2001-12-27  Akim Demaille  <akim@epita.fr>
3687
3688         * src/LR0.c (new_state): Recognize the final state by the fact it
3689         is reached by eoftoken.
3690         (insert_start_shifting_state, insert_eof_shifting_state)
3691         (insert_accepting_state, augment_automaton): Remove, since now
3692         these states are automatically computed from the initial state.
3693         (generate_states): Adjust.
3694         * src/print.c: When reporting a rule number to the user, substract
3695         1, so that the axiom rule is rule 0, and the first user rule is 1.
3696         * src/reduce.c: Likewise.
3697         * src/print_graph.c (print_core): For the time being, just as for
3698         the report, depend upon --trace-flags to dump the full set of
3699         items.
3700         * src/reader.c (readgram): Once the grammar read, insert the rule
3701         0: `$axiom: START-SYMBOL $'.
3702         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3703         number of the states has changed (the final state is no longer
3704         necessarily the last), catch up.
3705
3706 2001-12-27  Akim Demaille  <akim@epita.fr>
3707
3708         Try to make the use of the eoftoken valid.  Given that its value
3709         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3710         is used instead of > 0 where appropriate, (ii), depend upon nritems
3711         instead of the 0-sentinel.
3712
3713         * src/gram.h, src/gram.c (nritems): New.
3714         Expected to be duplication of nitems, but for the time being...
3715         * src/reader.c (packgram): Assert nritems and nitems are equal.
3716         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3717         * src/closure.c (print_closure, print_fderives): Likewise.
3718         * src/gram.c (ritem_print): Likewise.
3719         * src/print.c (print_core, print_grammar): Likewise.
3720         * src/print_graph.c: Likewise.
3721
3722 2001-12-27  Akim Demaille  <akim@epita.fr>
3723
3724         * src/main.c (main): If there are complains after grammar
3725         reductions, then output the report anyway if requested, then die.
3726         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3727         * src/reader.c (eoftoken): New.
3728         (parse_token_decl): If the token being defined has value `0', it
3729         is the eoftoken.
3730         (packsymbols): No longer hack `tags' to insert `$' by hand.
3731         Be sure to preserve the value of the eoftoken.
3732         (reader): Make sure eoftoken is defined.
3733         Initialize nsyms to 0: now eoftoken is created just like the others.
3734         * src/print.c (print_grammar): Don't special case the eof token.
3735         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3736         lie anyway, albeit pleasant.
3737         * tests/calc.at: Exercise error messages with eoftoken.
3738         Change the grammar so that empty input is invalid.
3739         Adjust expectations.
3740         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3741
3742 2001-12-27  Akim Demaille  <akim@epita.fr>
3743
3744         * configure.in: Check the protos of strchr ans strspn.
3745         Replace strchr if needed.
3746         * src/system.h: Provide the protos of strchr, strspn and memchr if
3747         missing.
3748         * lib/strchr.c: New.
3749         * src/reader.c (symbols_save): Use strchr.
3750
3751 2001-12-27  Akim Demaille  <akim@epita.fr>
3752
3753         * src/print.c, src/print_graph.c (escape): New.
3754         Use it to quote the TAGS outputs.
3755         * src/print_graph.c (print_state): Now errors are in red, and
3756         reductions in green.
3757         Prefer high to wide: output the state number on a line of its own.
3758
3759 2001-12-27  Akim Demaille  <akim@epita.fr>
3760
3761         * src/state.h, src/state.c (reductions_new): New.
3762         * src/LR0.c (set_state_table): Let all the states have a
3763         `reductions', even if reduced to 0.
3764         (save_reductions): Adjust.
3765         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

3767         * src/output.c (action_row): Adjust.
3768
3769 2001-12-27  Akim Demaille  <akim@epita.fr>
3770
3771         * src/state.h, src/state.c (errs_new, errs_dup): New.
3772         * src/LR0.c (set_state_table): Let all the states have an errs,
3773         even if reduced to 0.
3774         * src/print.c (print_errs, print_reductions): Adjust.
3775         * src/output.c (output_actions, action_row): Adjust.
3776         * src/conflicts.c (resolve_sr_conflict): Adjust.
3777
3778 2001-12-27  Akim Demaille  <akim@epita.fr>
3779
3780         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3781
3782 2001-12-27  Akim Demaille  <akim@epita.fr>
3783
3784         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3785         * src/print.c: here.
3786         (lookaheadset, shiftset): New, used as additional storage by
3787         print_reductions.
3788         (print_results): Adjust.
3789         (print_shifts, print_gotos, print_errs): New, extracted from...
3790         (print_actions): here.
3791         * src/print_graph.c (print_actions): Remove dead code.
3792
3793 2001-12-27  Akim Demaille  <akim@epita.fr>
3794
3795         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3796         `$n' and `@n'.
3797
3798 2001-12-27  Akim Demaille  <akim@epita.fr>
3799
3800         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3801         (build_relations): Adjust.
3802
3803 2001-12-27  Akim Demaille  <akim@epita.fr>
3804
3805         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3806         duplication.
3807
3808 2001-12-27  Akim Demaille  <akim@epita.fr>
3809
3810         * src/reader.c (packgram): Catch nitems overflows.
3811
3812 2001-12-27  Akim Demaille  <akim@epita.fr>
3813
3814         * src/files.c, src/files.h (guard_obstack): Remove.
3815         * src/output.c (output): Adjust.
3816         * src/reader.c (parse_braces): New, factoring...
3817         (copy_action, copy_guard): these two which are renamed as...
3818         (parse_action, parse_guard): these.
3819         As a voluntary consequence, using braces around guards is now
3820         mandatory.
3821
3822 2001-12-27  Akim Demaille  <akim@epita.fr>
3823
3824         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3825         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3826         members.
3827         (symbol_list_new): Adjust.
3828         (copy_action): action_line is the first line, not the last.
3829         (copy_guard): Just as for actions, store the `action' only, not
3830         the switch/case/break flesh.
3831         Don't parse the user action that might follow the guard, let...
3832         (readgram): do it, i.e., now, there can be an action after a
3833         guard.
3834         In other words the guard is just explicitly optional.
3835         (packgram): Adjust.
3836         * src/output.c (guards_output): New.
3837         (output_parser): Call it when needed.
3838         (output): Also free the guard and attrs obstacks.
3839         * src/files.c, src/files.h (obstack_save): Remove.
3840         (output_files): Remove.
3841         As a result, if one needs the former `.act' file, using an
3842         appropriate skeleton which requires actions and guards is now
3843         required.
3844         * src/main.c (main): Adjust.
3845         * tests/semantic.at: New.
3846         * tests/regression.at: Use `input.y' as input file name.
3847         Avoid 8+3 problems by requiring input.c when the test needs the
3848         parser.
3849
3850 2001-12-27  Akim Demaille  <akim@epita.fr>
3851
3852         * src/reader.c (symbol_list_new): Be sure to initialize all the
3853         fields.
3854
3855 2001-12-27  Akim Demaille  <akim@epita.fr>
3856
3857         All the hacks using a final pseudo state are now useless.
3858
3859         * src/LR0.c (set_state_table): state_table holds exactly nstates.
3860         * src/lalr.c (nLA): New.
3861         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3862         instead of lookaheadsp from the pseudo state (nstate + 1).
3863
3864 2001-12-27  Akim Demaille  <akim@epita.fr>
3865
3866         * src/output.c (action_row, token_actions): Use a state_t instead
3867         of a integer, and nlookaheads instead of the following state's
3868         lookaheadsp.
3869
3870 2001-12-27  Akim Demaille  <akim@epita.fr>

3874         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3875         (conflicts_print, print_reductions): Use a state_t instead of an
3876         integer when referring to a state.
3877         As much as possible, depend upon nlookaheads, instead of the
3878         `lookaheadsp' member of the following state (since lookaheads of
3879         successive states are successive, the difference between state n + 1
3880         and n served as the number of lookaheads for state n).
3881         * src/lalr.c (add_lookback_edge): Likewise.
3882         * src/print.c (print_core, print_actions, print_state)
3883         (print_results): Likewise.
3884         * src/print_graph.c (print_core, print_actions, print_state)
3885         (print_graph): Likewise.
3886         * src/conflicts.h: Adjust.

3888 2001-12-27  Akim Demaille  <akim@epita.fr>
3889
3890         * src/bison.hairy: Formatting/comment changes.
3891         ANSIfy.
3892         Remove `register' indications.
3893         Add plenty of `static'.
3894
3895 2001-12-27  Akim Demaille  <akim@epita.fr>
3896
3897         * src/output.c (prepare): Drop the muscle `ntbase' which
3898         duplicates ntokens.
3899         * src/bison.simple: Formatting/comment changes.
3900         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3901         is an undocumented synonym.
3902
3903 2001-12-22  Akim Demaille  <akim@epita.fr>
3904
3905         * src/output.c (output_table_data): Change the prototype to use
3906         `int' for array ranges: some invocations do pass an int, not a
3907         short.
3908         Reported by Wayne Green.

3913         Reported by Mike Castle.
3914
3915         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
3916         * tests/regression.at (Web2c): Rename as...
3917         (Web2c Report): this.
3918         (Web2c Actions): New.
3919

3922         Reductions in web2c.y are improperly reported.

3924
3925         * src/conflicts.c (print_reductions): Fix.
3926         * tests/regression.at (Web2c): New.
3927
3928 2001-12-18  Akim Demaille  <akim@epita.fr>
3929
3930         Some host fail on `assert (!"foo")', which expands to
3931         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3932         Reported by Nelson Beebee.
3933
3934         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3935         `#define it_succeeded 0' and `assert (it_succeeded)'.
3936
3937 2001-12-17  Marc Autret  <autret_m@epita.fr>
3938
3939         * src/bison.simple: Don't hard code the skeleton line and filename.
3940         * src/output.c (output_parser): Rename 'line' as 'output_line'.
3941         New line counter 'skeleton_line' (skeleton-line muscle).
3942
3943 2001-12-17  Paul Eggert  <eggert@twinsun.com>
3944
3945         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3946         YYDEBUG must be defined to a nonzero value.
3947
3948         * src/bison.simple (yytname): Do not assume that the user defines
3949         YYDEBUG to a properly parenthesized expression.
3950
3951 2001-12-17  Akim Demaille  <akim@epita.fr>
3952
3953         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3954         nlookaheads is a new member.
3955         Adjust all users.
3956         * src/lalr.h (nlookaheads): Remove this orphan declaration.

3963         * src/main.c (main): Don't open/close files, nor invoke lex_free,
3964         let...
3965         * src/reader.c (reader): Do it.
3966
3967 2001-12-17  Akim Demaille  <akim@epita.fr>
3968

3978
3979         * src/output.c (output_obstack): Be static and rename as...

3981         output_obstack.
3982         * src/reader.h (muscle_obstack): Move to...
3983         * src/output.h: here, since it's defined in output.c.
3984
3985 2001-12-17  Akim Demaille  <akim@epita.fr>
3986
3987         * src/output.c (action_row, save_column, default_goto)

3989         locality.

4004

4006         there is one less line per action.
4007
4008 2001-12-16  Marc Autret  <autret_m@epita.fr>
4009
4010         * src/bison.simple: Remove a useless #line directive.
4011         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4012         * src/output.c (get_lines_number): New.
4013         (output_parser): Adjust, now takes care about the lines of a
4014         output muscles.
4015         Fix line numbering.
4016         (actions_output): Computes the number of lines taken by actions.

4019
4020 2001-12-15  Marc Autret  <autret_m@epita.fr>

4027
4028 2001-12-15  Akim Demaille  <akim@epita.fr>
4029
4030         Make `make distcheck' work.
4031
4032         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4033         system.h which uses libgettext.h.
4034
4035 2001-12-15  Akim Demaille  <akim@epita.fr>
4036
4037         * src/nullable.c (set_nullable): Useless rules must be skipped,
4038         otherwise, since we range over their symbols, we might look at a
4039         nonterminal which no longer ``exists'', i.e., it is not counted in
4040         `nvars', hence we overflow our arrays.
4041
4042 2001-12-15  Akim Demaille  <akim@epita.fr>
4043
4044         The header can also be produced directly, without any obstack!

4050         * src/reader.c (parse_union_decl): No longer output to
4051         defines_obstack: its content can be found in the `stype' muscle
4052         anyway.
4053         (output_token_translations): Merge into...
4054         (symbols_output): this.

4062
4063         * src/reader.c (parse_union_decl): Instead of handling two obstack
4064         simultaneously, use one to define the `stype' muscle, and use the
4065         value of the latter to fill defines_obstack.
4066         (copy_comment): Remove.
4067         (copy_comment2): Work for a single obstack.
4068         Rename as...

4075
4076 2001-12-15  Akim Demaille  <akim@epita.fr>
4077
4078         Still making progress in separating Bison into (i) input, (ii)
4079         process, (iii) output: now we can directly output the parser file
4080         without using table_obstack at all.
4081
4082         * src/files.c, src/files.h (table_obstack): Bye bye.
4083         (parser_file_name): New.
4084         * src/files.c (compute_output_file_names): Compute it.

4087
4088 2001-12-15  Akim Demaille  <akim@epita.fr>
4089
4090         Attach actions to rules, instead of pre-outputting them to
4091         actions_obstack.
4092
4093         * src/gram.h (rule_t): action and action_line are new members.
4094         * src/reader.c (symbol_list): Likewise.
4095         (copy_action): Save the actions within the rule.
4096         (packgram): Save them in rule_table.
4097         * src/output.c (actions_output): New.

4099         (output_rule_data): Don't free rule_table.
4100         (output): Do it.
4101         (prepare): Don't save the `action' muscle.
4102         * src/bison.simple: s/%%action/%%actions/.

4104 2001-12-15  Akim Demaille  <akim@epita.fr>
4105
4106         * src/reader.c (copy_action): When --yacc, don't append a `;'
4107         to the user action: let it fail if lacking.
4108         Suggested by Arnold Robbins and Tom Tromey.
4109
4110 2001-12-14  Akim Demaille  <akim@epita.fr>
4111
4112         * src/lex.c (literalchar): Simply return the char you decoded, non
4113         longer mess around with obstacks and int pointers.
4114         Adjust all callers.
4115
4116 2001-12-14  Akim Demaille  <akim@epita.fr>
4117
4118         * src/lex.c (literalchar): Don't escape the special characters,
4119         just decode them, and keep them as char (before, eol was output as
4120         the 2 char string `\n' etc.).
4121         * src/output.c (output_rule_data): Use quotearg to output the
4122         token strings.
4123
4124 2001-12-13  Paul Eggert  <eggert@twinsun.com>
4125
4126         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4127         Do not infringe on the global user namespace when using C++.
4128         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4129         All uses of `fprintf' and `stderr' changed.
4130
4131         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4132
4133 2001-12-13  Akim Demaille  <akim@epita.fr>
4134
4135         The computation of nullable is broken: it doesn't handle empty
4136         RHS's properly.
4137
4138         * tests/torture.at (GNU AWK Grammar): New.
4139         * tests/sets.at (Nullable): New.
4140         * src/nullable.c (set_nullable): Instead of blindly looping over
4141         `ritems', loop over the rules, and then over their rhs's.
4142
4143         Work around Autotest bugs.
4144
4145         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4146         frame, because Autotest understand lines starting with a `+' as
4147         traces from the shell.  Then, they are not processed properly.
4148         Admittedly an Autotest bug, but we don't have time to wait for
4149         Autotest to catch up.
4150         * tests/regression.at (Broken Closure): Adjust to the new table
4151         frames.
4152         Move to...
4153         * tests/sets.at: here.
4154
4155 2001-12-13  Akim Demaille  <akim@epita.fr>
4156
4157         * src/closure.c (closure): Use nrules instead of playing tricks
4158         with BITS_PER_WORD.
4159
4160 2001-12-13  Akim Demaille  <akim@epita.fr>
4161
4162         * src/print.c (print_actions): Output the handling of `$' as the
4163         traces do: shifting the token EOF.  Before EOF was treated as a
4164         nonterminal.
4165         * tests/regression.at: Adjust some tests.
4166         * src/print_graph.c (print_core): Complete the set of items via
4167         closure.  The next-to-final and final states are still unsatisfying,
4168         but that's to be addressed elsewhere.
4169         No longer output the rule numbers, but do output the state number.
4170         A single loop for the shifts + gotos is enough, but picked a
4171         distinct color for each.
4172         (print_graph): Initialize and finalize closure.
4173
4174 2001-12-13  Akim Demaille  <akim@epita.fr>
4175
4176         * src/reader.c (readgram): Remove dead code, an strip useless
4177         braces.
4178         (get_type): Remove, unused.
4179
4180 2001-12-12  Akim Demaille  <akim@epita.fr>
4181
4182         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4183         on that of lib/error.c.
4184
4185 2001-12-12  Akim Demaille  <akim@epita.fr>
4186
4187         Some hosts don't like `/' in includes.
4188
4189         * src/system.h: Include libgettext.h without qualifying the path.
4190         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4191         $(top_srcdir).
4192
4193 2001-12-11  Marc Autret  <autret_m@epita.fr>
4194
4195         * src/output.c (output_parser): Remove useless muscle.
4196
4197 2001-12-11  Marc Autret  <autret_m@epita.fr>
4198
4199         * src/bison.simple: Remove #line just before %%epilogue. It
4200         is now handled in ...
4201         * src/reader.c (read_additionnal_code): Add the output of a
4202         #line for the epilogue.
4203
4204 2001-12-10  Marc Autret  <autret_m@epita.fr>
4205
4206         * src/reader.c (copy_definition): Re-use CPP-outed code which
4207         replace precedent remove.
4208         * src/bison.simple: Remove #line before %%prologue because
4209         %%input-line is wrong at this time.
4210
4211 2001-12-10  Marc Autret  <autret_m@epita.fr>
4212
4213         * src/reader.c (symbols_output): Clean up.
4214         * src/output.c (output_gram, output): Clean up.
4215
4216 2001-12-10  Akim Demaille  <akim@epita.fr>
4217
4218         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
4219         * src/LR0.c (set_state_table): here.
4220         * src/lalr.c (lalr): Call it.
4221
4222 2001-12-10  Akim Demaille  <akim@epita.fr>
4223
4224         * src/state.h (shifts): Remove the `number' member: shifts are
4225         attached to state, hence no longer need to be labelled with a
4226         state number.
4227
4228 2001-12-10  Akim Demaille  <akim@epita.fr>
4229
4230         Now that states have a complete set of members, the linked list of
4231         shifts is useless: just fill directly the state's shifts member.
4232
4233         * src/state.h (shifts): Remove the `next' member.
4234         * src/LR0.c (first_state, last_state): Remove.
4235         Adjust the callers.
4236         (augment_automaton): Don't look for the shifts that must be added
4237         a shift on EOF: it is those of the state we looked for!  But now,
4238         since shifts are attached, it is no longer needed to looking
4239         merely by its id: its number.
4240
4241 2001-12-10  Akim Demaille  <akim@epita.fr>
4242
4243         * src/LR0.c (augment_automaton): Better variable locality.
4244         Remove an impossible branch: if there is a state corresponding to
4245         the start symbol being shifted, then there is shift for the start
4246         symbol from the initial state.
4247
4248 2001-12-10  Akim Demaille  <akim@epita.fr>
4249
4250         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4251         only when appropriate: when insert_start_shifting_state' is not
4252         invoked.
4253         * tests/regression.at (Rule Line Numbers): Adjust.
4254
4255 2001-12-10  Akim Demaille  <akim@epita.fr>
4256
4257         * src/LR0.c (augment_automaton): Now that all states have shifts,
4258         merge the two cases addition shifts to the initial state.
4259
4260 2001-12-10  Akim Demaille  <akim@epita.fr>
4261
4262         * src/lalr.c (set_state_table): Move to...
4263         * src/LR0.c: here.
4264         * src/lalr.c (lalr): Don't call it...
4265         * src/LR0.c (generate_states): do it.
4266         * src/LR0.h (first_state): Remove, only the table is used.
4267
4268 2001-12-10  Akim Demaille  <akim@epita.fr>
4269
4270         * src/LR0.h (first_shift, first_reduction): Remove.
4271         * src/lalr.c: Don't use first_shift: find shifts through the
4272         states.
4273
4274 2001-12-10  Akim Demaille  <akim@epita.fr>
4275
4276         * src/LR0.c: Attach shifts to states as soon as they are
4277         computed.
4278         * src/lalr.c (set_state_table): Instead of assigning shifts to
4279         state, just assert that the mapping was properly done.
4280
4281 2001-12-10  Akim Demaille  <akim@epita.fr>
4282
4283         * src/LR0.c (insert_start_shift): Rename as...
4284         (insert_start_shifting_state): this.
4285         (insert_eof_shifting_state, insert_accepting_state): New.
4286         (augment_automaton): Adjust.
4287         Better locality of the variables.
4288         When looking if the start_symbol is shifted from the initial
4289         state, using `while (... symbol != start_symbol ...)' sounds
4290         better than `while (... symbol < start_symbol ...)': If fail
4291         to see how the order between symbols could be relevant!
4292
4293 2001-12-10  Akim Demaille  <akim@epita.fr>
4294
4295         * src/getargs.h: Don't declare `spec_name_prefix' and
4296         `spec_file_prefix', declared by src/files.h.
4297         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4298         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4299         * src/output.c (prepare): Adjust.
4300         * src/reader.c (symbols_output): Likewise.
4301         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4302
4303 2001-12-10  Akim Demaille  <akim@epita.fr>
4304
4305         * src/muscle_tab.c (muscle_init): NULL is a better default than
4306         `"0"'.
4307
4308 2001-12-10  Akim Demaille  <akim@epita.fr>
4309
4310         * src/reader.c (reader): Calling symbols_output once is enough.
4311
4312 2001-12-10  Akim Demaille  <akim@epita.fr>
4313
4314         Now that states have a complete set of members, the linked list of
4315         reductions is useless: just fill directly the state's reductions
4316         member.
4317
4318         * src/state.h (struct reductions): Remove member `number' and
4319         `next'.
4320         * src/LR0.c (first_reduction, last_reduction): Remove.
4321         (save_reductions): Don't link the new reductions, store them in
4322         this_state.
4323         * src/lalr.c (set_state_table): No need to attach reductions to
4324         states, it's already done.
4325         * src/output.c (output_actions): No longer free the shifts, then
4326         the reductions, then the states: free all the states and their
4327         members.
4328
4329 2001-12-10  Akim Demaille  <akim@epita.fr>
4330
4331         * src/options.c (OPTN, DRTV, BOTH): New.
4332         (option_table): Use them.
4333
4334         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4335         the job of system.h.
4336         * src/options.c: Don't include stdio.h and xalloc.h for the same
4337         reasons.
4338
4339 2001-12-10  Akim Demaille  <akim@epita.fr>
4340
4341         * src/output.c (output, prepare): Make sure the values of the
4342         muscles `action' and `prologue' are 0-terminated.
4343
4344 2001-12-10  Akim Demaille  <akim@epita.fr>
4345
4346         Clean up GCC warnings.
4347
4348         * src/reader.c (copy_action): `buf' is not used.
4349         (parse_skel_decl): Be static.
4350         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4351         * src/options.h (create_long_option_table): Have a real prototype.
4352         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4353         (hash_delete_at): Return const void *.
4354         Adjust casts to preserve the const.
4355
4356 2001-12-10  Akim Demaille  <akim@epita.fr>
4357
4358         * configure.in: Require 2.52g.
4359         M4 is not needed, but AUTOM4TE is.
4360         * m4/m4.m4: Remove.
4361         * tests/Makefile.am: Adjust.
4362
4363 2001-12-10  Akim Demaille  <akim@epita.fr>
4364
4365         One structure for states is enough, even though theoretically
4366         there are LR(0) states and LALR(1) states.
4367
4368         * src/lalr.h (state_t): Remove.
4369         (state_table): Be state_t **, not state_t *.
4370         * src/state.h (core, CORE_ALLOC): Rename as...
4371         (state_t, STATE_ALLOC): this.
4372         Add the LALR(1) members: shifts, reductions, errs.
4373         * src/LR0.c (state_table): Rename as...
4374         (state_hash): this, to avoid name clashes with the global
4375         `state_table'.
4376         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4377         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

4379 2001-12-10  Akim Demaille  <akim@epita.fr>
4380
4381         Bison dumps core on bash.y.
4382         Reported by Pascal Bart.
4383
4384         * src/warshall.c (bitmatrix_print): New.
4385         (TC): Use it.
4386         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4387         j must be the outer loop.
4388         * tests/regression.at (Broken Closure): New.
4389
4390 2001-12-05  Akim Demaille  <akim@epita.fr>
4391
4392         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4393         its argument.
4394         Reported by Peter Hámorský.
4395
4396 2001-12-05  Akim Demaille  <akim@epita.fr>
4397
4398         * src/conflicts.c (err_table): Remove.
4399         (resolve_sr_conflict): Adjust.
4400         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4401         Rename as...
4402         (state_t.reductions, state_t.shifts): this.
4403
4404 2001-12-05  Akim Demaille  <akim@epita.fr>
4405
4406         * src/reduce.c (reduce_grammar_tables): No longer disable the
4407         removal of useless rules via CPP but via `if (0)', so that the
4408         compiler still check the code is valid.
4409         For instance, it should have noticed `rline' no longer exists: use
4410         the `line' member of rule_t.
4411         * src/gram.c (dummy, rline): Remove, unused.
4412
4413 2001-12-05  Akim Demaille  <akim@epita.fr>
4414
4415         * src/output.c (pack_vector): Use assert, not berror.
4416         * src/main.c (berror): Remove, unused.
4417
4418 2001-12-05  Akim Demaille  <akim@epita.fr>
4419
4420         New experimental feature: if --verbose --trace output all the
4421         items of a state, not only its kernel.
4422
4423         * src/print.c (print_core): If `trace_flag', then invoke closure
4424         before outputting the items of the state (print_core is no longer
4425         a correct name them).
4426         (print_results): Invoke new_closure/free_closure if needed.
4427
4428 2001-12-05  Akim Demaille  <akim@epita.fr>
4429
4430         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4431         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4432         (nitemset): for consistency with the rest of the project.
4433
4434 2001-12-05  Akim Demaille  <akim@epita.fr>
4435
4436         * src/closure.c (print_closure): Improve.
4437         (closure): Use it for printing input and output.
4438
4439 2001-12-05  Akim Demaille  <akim@epita.fr>
4440
4441         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4442         indexed by nonterminals.
4443
4444 2001-12-05  Akim Demaille  <akim@epita.fr>
4445
4446         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4447         what it was!).
4448         * src/warshall.h: Remove accidental duplication of the content.
4449

4464         * src/output.c (action_row): De-obfuscate
4465         using the good o' techniques: arrays not pointers, variable
4466         locality, BITISSET, RESETBIT etc.
4467
4468 2001-12-05  Akim Demaille  <akim@epita.fr>
4469
4470         Pessimize the code to simplify it: from now on, all the states
4471         have a valid SHIFTS, which NSHIFTS is possibly 0.
4472
4473         * src/LR0.c (shifts_new): Be global and move to..
4474         * src/state.c, src/state.h: here.
4475         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4476         * src/print_graph: Adjust.
4477
4478 2001-12-05  Akim Demaille  <akim@epita.fr>
4479
4480         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4481         * src/conflicts.c: Use it.
4482         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4483         incorrectly ``simplified''.
4484
4485 2001-12-05  Akim Demaille  <akim@epita.fr>
4486
4487         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4488         using the good o' techniques: arrays not pointers, variable
4489         locality, BITISSET, RESETBIT etc.
4490
4491 2001-12-05  Akim Demaille  <akim@epita.fr>
4492
4493         * src/state.h (SHIFT_SYMBOL): New.
4494         * src/conflicts.c: Use it to deobfuscate.
4495
4496 2001-12-05  Akim Demaille  <akim@epita.fr>
4497
4498         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4499         (print_reductions): De-obfuscate using the good o' techniques:
4500         arrays not pointers, variable locality, BITISSET.
4501
4502 2001-12-05  Akim Demaille  <akim@epita.fr>
4503
4504         * src/conflicts.c (print_reductions): Arrays, not pointers.
4505         Use BITISSET.
4506
4507 2001-12-05  Akim Demaille  <akim@epita.fr>
4508
4509         * src/conflicts.c (print_reductions): Pessimize, but clarify.
4510
4511 2001-12-05  Akim Demaille  <akim@epita.fr>
4512
4513         * src/conflicts.c (print_reductions): Improve variable locality.

4522
4523 2001-12-05  Akim Demaille  <akim@epita.fr>
4524
4525         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
4526         * src/lalr.c: Use them.
4527
4528 2001-12-05  Akim Demaille  <akim@epita.fr>
4529
4530         * src/LR0.c (augment_automaton): Formatting changes.
4531         Better variable locality.
4532
4533 2001-12-05  Akim Demaille  <akim@epita.fr>
4534
4535         * src/lalr.c (matrix_print): New.
4536         (transpose): Use it.
4537         Use arrays instead of pointers.
4538
4539 2001-12-05  Akim Demaille  <akim@epita.fr>
4540
4541         * src/lalr.c (maxrhs): Move to...
4542         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4543         * src/lalr.c (build_relations): Adjust.
4544
4545 2001-12-05  Akim Demaille  <akim@epita.fr>
4546
4547         * src/lalr.c (transpose): Free the memory allocated to the
4548         argument, as it is replaced by the results by the unique caller.
4549         (build_relations): Merely invoke transpose: it handles the memory
4550         deallocation.
4551         Improve variable locality.
4552         Avoid variables used as mere abbreviations.
4553         (compute_lookaheads): Use arrays instead of pointers.
4554
4555 2001-12-05  Akim Demaille  <akim@epita.fr>
4556
4557         * src/lalr.c (initialize_F): Improve variable locality.
4558         Avoid variables used as mere abbreviations.
4559
4560 2001-12-05  Akim Demaille  <akim@epita.fr>
4561
4562         * src/derives.c (print_derives): Display the ruleno.
4563         * src/lalr.c (initialize_F, transpose): Better variable locality
4564         to improve readability.
4565         Avoid variables used as mere abbreviations.
4566
4567 2001-12-05  Akim Demaille  <akim@epita.fr>
4568
4569         * src/lalr.c (traverse): Use arrays instead of pointers.
4570
4571 2001-12-05  Akim Demaille  <akim@epita.fr>
4572
4573         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4574         the handling of squeue.
4575         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4576
4577 2001-12-05  Akim Demaille  <akim@epita.fr>
4578
4579         Because useless nonterminals are now kept alive (instead of being
4580         `destroyed'), we now sometimes examine them, and store information
4581         related to them.  Hence we need to know their number, and adjust
4582         memory allocations.
4583
4584         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4585         static.
4586         * src/LR0.c (allocate_itemsets): The memory allocated to
4587         `symbol_count' was used for two different purpose: once to count
4588         the number of occurrences of each symbol, and later reassigned to
4589         `shift_symbol', containing the symbol that can be shifted from a
4590         given state.
4591         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4592         only, and...
4593         (new_itemsets): Allocate `shift_symbol' here.
4594         (allocate_itemsets): symbol_count includes useless nonterminals.
4595         Make room for them.
4596         (free_storage): Use `free', not `XFREE', for pointers that cannot
4597         be null.
4598
4599 2001-12-05  Akim Demaille  <akim@epita.fr>
4600
4601         * src/nullable.c (set_nullable): Deobfuscate the handling of
4602         ritem.
4603         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4604
4605 2001-12-05  Akim Demaille  <akim@epita.fr>
4606
4607         * src/gram.c, src/gram.h (ritem_print): New.
4608         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4609         (This useless function was defined only to work around VMS linkers
4610         that can't handle compilation units with variables only).
4611         * src/reduce.c (dump_grammar): Use it to trace the construction of
4612         ritem.
4613
4614 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4615
4616         * src/bison.simple (union yyalloc): Change member names
4617         to be the same as the stack names.
4618         (yyparse): yyptr is now union yyalloc *, not char *.
4619         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4620         and may generate better code on some machines.
4621         (yystpcpy): Use prototype if __STDC__ is defined, not just
4622         if __cplusplus is defined.
4623
4624 2001-11-30  Akim Demaille  <akim@epita.fr>
4625
4626         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4627         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4628         Gettext doesn't compile cleanly, and dies with -Werror.
4629         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4630         Include WARNING_CFLAGS here.
4631         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4632         before being defined.
4633
4634 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4635
4636         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4637         First arg is int, not unsigned.
4638         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4639         (SIZE_MAX, UINT_MAX): New macros.
4640         (quotearg_n_options): Abort if N is negative.
4641         Avoid overflow check on hosts where size_t is 64 bits and int
4642         is 32 bits, as overflow is impossible there.
4643         Fix off-by-one typo that caused unnecessary reallocation.
4644
4645 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4646
4647         Name space cleanup in generated parser.
4648
4649         * doc/bison.texinfo (Bison Parser): Discuss system headers
4650         and their effect on the user name space.
4651
4652         * src/bison.simple:
4653         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4654         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4655         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4656
4657         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4658         on user names when possible.
4659
4660         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4661         Simplify test for whather <alloca.h> exists.
4662
4663         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4664
4665         (<stdio.h>): Include if YYDEBUG.
4666
4667         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4668         ! defined (yyoverflow) && ! defined (yymemcpy).
4669
4670         (yymemcpy, yyparse): Rename local variables as needed so that
4671         they all begin with 'yy'.
4672
4673         (yystrlen, yystpcpy): New functions.
4674
4675         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4676         All uses changed.
4677
4678         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4679         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4680         and YYSTACK_FREE instead of malloc and free.
4681
4682 2001-11-30  Akim Demaille  <akim@epita.fr>
4683
4684         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4685         before their first uses.
4686         (YYBISON, YYPURE): Move to the top of the output.
4687

4691
4692 2001-11-30  Akim Demaille  <akim@epita.fr>
4693
4694         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4695         if body instead of `;' to pacify GCC's warnings.
4696
4697 2001-11-30  Akim Demaille  <akim@epita.fr>
4698
4699         Instead of mapping the LHS of unused rules to -1, keep the LHS
4700         valid, but flag the rules as invalid.
4701
4702         * src/gram.h (rule_t): `useful' is a new member.
4703         * src/print.c (print_grammar): Adjust.
4704         * src/derives.c (set_derives): Likewise.
4705         * src/reader.c (packgram, reduce_output): Likewise.
4706         * src/reduce.c (reduce_grammar_tables): Likewise.
4707         * tests/reduce.at (Underivable Rules, Useless Rules): New.
4708
4709 2001-11-30  Akim Demaille  <akim@epita.fr>
4710
4711         * src/reduce.c (reduce_output): Formatting changes.
4712         * src/print.c (print_results, print_grammar): Likewise.
4713         * tests/regression.at (Rule Line Numbers)
4714         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4715
4716 2001-11-30  Akim Demaille  <akim@epita.fr>
4717
4718         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4719         useless nonterminals, move them at the end of the symbol arrays.
4720         (reduce_output): Adjust.
4721         * tests/reduce.at (Useless Nonterminals): Adjust.
4722
4723 2001-11-30  Akim Demaille  <akim@epita.fr>
4724
4725         * src/reduce.c: Various comment/formatting changes.
4726         (nonterminals_reduce): New, extracted from...
4727         (reduce_grammar_tables): here.
4728         (reduce_grammar): Call nonterminals_reduce.
4729
4730 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4731
4732         * src/bison.simple (YYSTACK_REALLOC): Remove.
4733         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4734         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4735         New macros.
4736         (union yyalloc): New type.
4737         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4738         an arbitrary restriction on hosts where size_t is wider than int.
4739
4740         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4741         a parser stack overflow.  Allocate just one block of memory for all
4742         three stacks, instead of allocating three blocks; this typically is
4743         faster and reduces fragmentation.
4744
4745         Do not limit the number of items in the stack to a value that fits
4746         in 'int', as this is an arbitrary limit on hosts with 64-bit
4747         size_t and 32-bit int.
4748
4749 2001-11-29  Marc Autret  <autret_m@epita.fr>
4750
4751         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4752         of defining YYERROR_VERBOSE.
4753         [AT_DATA]: $4 is now out of C declarations in the prologue.
4754
4755 2001-11-28  Marc Autret  <autret_m@epita.fr>
4756
4757         * src/reader.c (parse_dquoted_param): New.
4758         (parse_skel_decl): Use it.
4759         * src/lex.h: Add its prototype.
4760         * src/lex.c (literalchar): Become not static.
4761
4762 2001-11-28  Marc Autret  <autret_m@epita.fr>
4763
4764         * src/output.h: And put its extern declaration here.
4765         * src/output.c (error_verbose): Define here.
4766         (prepare): Echo name modification.
4767         * src/getargs.h: Clean its extern declaration.
4768         * src/getargs.c (error_verbose_flag): Remove.
4769         (getargs): Remove case 'e'.
4770         * src/options.c (option_table): 'error-verbose' is now seen as simple
4771         percent option.
4772         Include output.h.
4773
4774         * src/reader.c (read_declarations): Remove case tok_include.
4775         (parse_include_decl): Remove.
4776         * src/lex.h (token_t): Remove tok_include.
4777         * src/options.c (option_table): 'include' is now a simple command line
4778         option.
4779
4780 2001-11-28  Marc Autret  <autret_m@epita.fr>
4781
4782         * src/bison.simple: Adjust muscle names.
4783         * src/muscle_tab.c (muscle_init): Also rename the muscles.
4784         * src/output.c (prepare): s/_/-/ for the muscles names.
4785         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
4786
4787 2001-11-28  Marc Autret  <autret_m@epita.fr>

4795         (save_shifts, insert_start_shift, augment_automaton): Use it.
4796
4797 2001-11-28  Akim Demaille  <akim@epita.fr>
4798
4799         * src/closure.c (closure): `b' and `ruleno' denote the same value:
4800         keep ruleno only.
4801
4802 2001-11-28  Akim Demaille  <akim@epita.fr>
4803
4804         * src/closure.c (closure): Instead of looping over word in array
4805         then bits in words, loop over bits in array.
4806
4807 2001-11-28  Akim Demaille  <akim@epita.fr>
4808
4809         * src/closure.c (closure): No longer optimize the special case
4810         where all the bits of `ruleset[r]' are set to 0, to make the code
4811         clearer.
4812
4813 2001-11-28  Akim Demaille  <akim@epita.fr>
4814
4815         * src/closure.c (closure): `r' and `c' are new variables, used to
4816         de-obfuscate accesses to RULESET and CORE.
4817
4818 2001-11-28  Akim Demaille  <akim@epita.fr>

6748         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it

6750         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6751         cast the value to (void *): assigning a `foo *' to a `void *'

6958         * bison.s1 (yyparse): Assign the default value
6959         unconditionally, to avoid a GCC warning and make the parser a
6960         tad smaller.
6961
6962 2000-10-02  Akim Demaille  <akim@epita.fr>
6963
6964         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
6965         options.
6966
6967 2000-10-02  Akim Demaille  <akim@epita.fr>
6968
6969         * src/derives.c, src/print.c, src/reduce.c: To ease the
6970         translation, move some `\n' out of the translated strings.
6971
6972 2000-10-02  Akim Demaille  <akim@epita.fr>
6973
6974         The location tracking mechanism is precious for parse error
6975         messages.  Nevertheless, it is enabled only when `@n' is used in
6976         the grammar, which is a different issue (you can use it in error
6977         message, but not in the grammar per se).  Therefore, there should
6978         be another means to enable it.
6979
6980         * src/getargs.c (getargs): Support `--locations'.
6981         (usage): Report it.
6982         * src/getargs.h (locationsflag): Export it.
6983         * src/lex.c (percent_table): Support `%locations'.
6984         * src/reader.c (yylsp_needed): Remove this variable, now replaced
6985         with `locationsflag'.
6986         * doc/bison.texinfo: Document `--locations' and `%locations'.
6987         Sort the options.
6988         * tests/calc.m4: Test it.
6989
6990         For regularity of the names, replace each
6991         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6992         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6993         In addition replace each `flag' with `_flag'.
6994
6995 2000-10-02  Akim Demaille  <akim@epita.fr>
6996
6997         Also test parse error messages, including with YYERROR_VERBOSE.
6998
6999         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7000         associative).
7001         Use it to check the computations.
7002         Use it to check `nonassoc' is honored.
7003         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7004         `--yyerror-verbose'.
7005         (_AT_CHECK_CALC): Adjust to this option.
7006         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7007
7008 2000-10-02  Akim Demaille  <akim@epita.fr>
7009
7010         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
7011         the latter demonstrates a flaw in the handling of non debugging
7012         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7013         was used in order to simplify:
7014
7015         #if YYDEBUG
7016         if (yydebug)
7017         {
7018         ...
7019         }
7020         #endif
7021
7022         into
7023
7024         if (yydebug)
7025         {
7026         ...
7027         }
7028
7029         unfortunately this leads to a CPP conflict when
7030         `--name-prefix=foo' is used since it produces `#define yydebug
7031         foodebug'.
7032
7033         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7034         (YYDPRINTF): New macro.
7035         Spread its use.
7036         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7037         the bison options.
7038         Also test `--verbose', `--defines' and `--name-prefix'.
7039
7040 2000-10-02  Akim Demaille  <akim@epita.fr>
7041
7042         Improve the readability of the produced parsers.
7043
7044         * src/bison.s1: Formatting changes.
7045         Improve the comment related to the `$' mark.
7046         (yydefault): Don't fall through to `yyresume': `goto' there.
7047         * src/output.c (output_parser): When the `$' is met, skip the end
7048         of its line.
7049         New variable, `number_of_dollar_signs', to check there's exactly
7050         one `$' in the parser skeleton.
7051
7052 2000-10-02  Akim Demaille  <akim@epita.fr>
7053
7054         * lib/xstrdup.c: New file, from the fileutils.
7055         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7056         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7057         instead of strlen + xmalloc + strcpy.
7058         * src/symtab.c (copys): Remove, use xstrdup instead.
7059
7060 2000-10-02  Akim Demaille  <akim@epita.fr>
7061
7062         * src/gram.h (associativity): New enum type which replaces the
7063         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7064         `right_assoc', `left_assoc' and `non_assoc'.
7065         Adjust all dependencies.
7066         * src/reader.c: Formatting changes.
7067         (LTYPESTR): Don't define it, use it as a literal in
7068         `reader_output_yylsp'.
7069         * src/symtab.h (symbol_class): New enum type which replaces the
7070         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7071         `sunknown', `stoken and `snterm'.
7072
7073 2000-10-02  Akim Demaille  <akim@epita.fr>
7074
7075         * src/getargs.c (fixed_outfiles): Rename as...
7076         (yaccflag): for consistency and accuracy.
7077         Adjust dependencies.
7078
7079 2000-10-02  Akim Demaille  <akim@epita.fr>
7080
7081         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7082         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
7083         difficult and introduced a lot of core dump.  It turns out that
7084         Bison used an implementation of `xmalloc' based on `calloc', and
7085         at various places it does depend upon the initialization to 0.  I
7086         have not tried to isolate the pertinent places, and all the former
7087         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
7088         someone should address this issue.
7089
7090         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7091         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7092         files.
7093         Adjust dependencies.
7094         * src/warshall.h: New file.
7095         Propagate.
7096
7097 2000-10-02  Akim Demaille  <akim@epita.fr>
7098
7099         Various anti-`extern in *.c' changes.
7100
7101         * src/system.h: Include `assert.h'.
7102
7103 2000-10-02  Akim Demaille  <akim@epita.fr>
7104
7105         * src/state.h (nstates, final_state, first_state, first_shift)
7106         (first_reduction): Move their exportation from here...
7107         * src/LR0.h: to here.
7108         Adjust dependencies.
7109         * src/getargs.c (statisticsflag): New variable.
7110         Add support for `--statistics'.
7111         Adjust dependencies.
7112
7113         Remove a lot of now useless `extern' statements in most files.

7123         Propagate its use.
7124         * src/print.c: Formatting and ordering changes.
7125         (verbose, terse): Replace with...

7127         Adjust dependencies.
7128
7129 2000-10-02  Akim Demaille  <akim@epita.fr>

7159         Propagate its use.
7160
7161 2000-10-02  Akim Demaille  <akim@epita.fr>
7162
7163         * src/reader.h: New file.

7177 2000-10-02  Akim Demaille  <akim@epita.fr>
7178
7179         * src/lalr.h: New file.

7181         * src/lalr.c: Formatting changes, topological sorting etc.
7182
7183 2000-10-02  Akim Demaille  <akim@epita.fr>
7184
7185         * src/output.c (token_actions): Introduce a temporary array,
7186         YYDEFACT, that makes it possible for this function to use
7187         output_short_table.
7188
7189 2000-10-02  Akim Demaille  <akim@epita.fr>
7190
7191         `user_toknums' is output as a `short[]' in `output.c', while it is
7192         defined as a `int[]' in `reader.c'.  For consistency with the
7193         other output tables, `user_toknums' is now defined as a table of
7194         shorts.
7195
7196         * src/reader.c (user_toknums): Be a short table instead of an int
7197         table.
7198         Adjust dependencies.

7202         * src/output.c (output_short_table): New function.
7203         * src/output.c (output_gram, output_stos, output_rule_data)
7204         (output_base, output_table, output_check):  Use it.
7205
7206 2000-10-02  Akim Demaille  <akim@epita.fr>
7207
7208         * src/output.c (output): Topological sort of the functions, in
7209         order to get rid of the `static' prototypes.
7210         No longer use `register'.
7211         * src/output.h: New file.
7212         Propagate its inclusion in files explicitly prototyping functions
7213         from output.c.

7220

7222         * src/closure.c: Formatting changes, topological sort over the
7223         functions, use of closure.h.
7224         (initialize_closure, finalize_closure):  Rename as...
7225         (new_closure, free_closure): these.  Adjust dependencies.
7226         * src/LR0.c: Formatting changes, topological sort, use of
7227         cloture.h.
7228         (initialize_states): Rename as...

7232 2000-09-20  Akim Demaille  <akim@epita.fr>
7233
7234         * src/acconfig.h: Don't protect config.h against multiple
7235         inclusion.
7236         Don't define PARAMS.
7237         * src/system.h: Define PARAMS.
7238         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7239         purpose of config.h.  system.h must not try to fix wrong
7240         definitions in config.h.
7241
7242 2000-09-20  Akim Demaille  <akim@epita.fr>

7254         Use these macros to test bison with options `', `--raw',
7255         `--debug', `--yacc', `--yacc --debug'.
7256

7258
7259         * src/output.c: Formatting changes.

7264         * src/getargs.h: New file.
7265         Let all `extern' declarations about getargs.c be replaced with

7277         portable.
7278
7279 2000-09-18  Akim Demaille  <akim@epita.fr>
7280
7281         * configure.in: Append WARNING_CFLAGS to CFLAGS.
7282         * src/Makefile.am (INCLUDES): Don't.
7283         Be ready to fetch headers in lib/.
7284
7285 2000-09-18  Akim Demaille  <akim@epita.fr>
7286

7294
7295         * src/bison.s1 (yyparse): Condition the code using `yytname' which
7296         is defined only when YYDEBUG is.

7403
7404 2000-03-17  Akim Demaille  <akim@epita.fr>
7405
7406         On syntax errors, report the token on which we choked.

7429         `cplus_comment'.
7430         (copy_comment, copy_string): Moved, to be visible from

7457
7458         Change the handling of @s so that they behave exactly like $s.
7459         There is now a pseudo variable @$ (readble and writable), location
7460         of the lhs of the rule (by default ranging from the location of
7461         the first symbol of the rhs, to the location of the last symbol,
7462         or, if the rhs is empty, YYLLOC).
7463
7464         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7465         yyval.
7466         (yyparse): When providing a default semantic action, provide a
7467         default location action.
7468         (after the $): No longer change `*YYLSP', just stack YYLOC the
7469         same way you stack YYVAL.
7470         * src/reader.c (read_declarations): Use warns.
7471         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7472         (copy_action, case '@'): Likewise.
7473         Use a standard error message, to save useless work from
7474         translators.
7475
7476 2000-03-17  Akim Demaille  <akim@epita.fr>
7477

7495
7496         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7497         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7498         One `#if YYDEBUG' remains, since it uses variables which are
7499         defined only if `YYDEBUG != 0'.
7500
7501 2000-03-16  Akim Demaille  <akim@epita.fr>
7502
7503         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

7525         handled via src/Makefile.am.

7527         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
7528         autoheader.

7533         the proper line number and file name.
7534         (DEFS): Propagate the location of bison library files and of the
7535         locale files.
7536         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7537         builddir.
7538         * acinclude.m4: Remove, replaced by the directory m4.
7539         * m4/Makefile.am (EXTRA_DIST): New variable.
7540         * m4/gettext.m4: New file, from the fileutils.

8226         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
8227         major changes to files.c.
8228         (lex) Retain in the incoming stream a character following
8229         an incorrect '/'.
8230         (skip_white_space, lex):  Revised most error messages
