   4         * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
   5         Include <sys/time.h> when checking for clock_t and struct tms.
   6         Use same include order as source.
   7         This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
   8         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.

  10         * lib/timevar.c: Update copyright date and clarify comments.
  11         (get_time) [IN_GCC]: Keep the GCC version for reference.
  12
  13         * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
  14         GCC version as of today, then merge Bison's changes.
  15         Change "GCC" to "Bison" in copyright notice.  timevar.def's
  16         author is Akim, so change that too.
  17
  18         * src/reader.c (grammar_current_rule_check):
  19         Don't worry about the default action if $$ is untyped.

  23         * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
  24         * data/glr.c, data/lalr1.cc, data/yacc.c:
  25         Output token definitions before the first part of user declarations.
  26         Fixes compatibility problem reported by Jim Gifford for kbd in
  27         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.

  29 2002-10-11  Paul Eggert  <eggert@twinsun.com>
  30
  31         * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
  32         (yyparse): here.  This undoes some of the 2002-07-25 change.
  33         Compatibility problem reported by Ralf S. Engelschall with
  34         OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

  46
  47 2002-10-10  Paul Eggert  <eggert@twinsun.com>
  48
  49         Portability fixes for bitsets; this also avoids several GCC
  50         warnings.
  51
  52         * lib/abitset.c: Include <stddef.h>, for offsetof.
  53         * lib/lbitset.c: Likewise.
  54
  55         * lib/abitset.c (abitset_bytes): Return a size that is aligned
  56         properly for vectors of objects.  Do not assume that adding a
  57         header size to a multiple of a word size yields a value that is
  58         properly aligned for the whole union.
  59         * lib/bitsetv.c (bitsetv_alloc): Likewise.
  60
  61         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
  62         unique names for structures.
  63         * lib/ebitset.c (ebitset_bytes): Likewise.
  64         * lib/lbitset.c (lbitset_bytes): Likewise.
  65
  66         * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
  67         abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
  68         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
  69         abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
  70         abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
  71         abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
  72         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
  73         to improve the type-checking that GCC can do.
  74         * lib/bitset.c (bitset_op4_cmp): Likewise.
  75         * lib/bitset_stats.c (bitset_stats_count,
  76         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
  77         bitset_stats_copy, bitset_stats_disjoint_p,
  78         bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
  79         bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
  80         bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
  81         bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
  82         bitset_stats_and_or_cmp, bitset_stats_andn_or,
  83         bitset_stats_andn_or_cmp, bitset_stats_or_and,
  84         bitset_stats_or_and_cmp): Likewise.
  85         * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
  86         lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
  87         lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
  88         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
  89
  90         * lib/abitset.h: Include bitset.h, not bbitset.h.
  91         * lib/ebitset.h: Likewise.
  92         * lib/lbitset.h: Likewise.
  93
  94         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
  95         All instances of parameters of type enum bitset_opts are now of
  96         type enum_bitset_opts, to conform to the C Standard, and similarly
  97         for enum_bitset_type.
  98         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
  99         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
 100
 101         Do not use "struct bitset_struct" to mean different things in
 102         different modules.  Not only is this confusing, it violates
 103         the C Standard, which requires that structure types in different
 104         modules must be compatible if one is to be passed to the other.
 105         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
 106         All instances of "struct bitset_struct *" replaced with "bitset".
 107         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
 108         (union bitset_union, struct abitset_struct, struct ebitset_struct,
 109         struct lbitset_struct, struct bitset_stats_struct): New types.
 110         All uses of struct bitset_struct changed to union bitset_union,
 111         etc.
 112         * lib/abitset.c (struct abitset_struct, abitset,
 113         struct bitset_struct): Remove.
 114         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
 115         struct bitset_struct): Remove.
 116         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
 117         bitset_struct): Remove.
 118         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
 119         Likewise.
 120
 121         Do not call a function of type T using a call that assumes the
 122         function is of a different type U.  Standard C requires that a
 123         function must be called with a type that is compatible with its
 124         definition.
 125         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 126         New decls.
 127         * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 128         New functions.
 129         * lib/ebitset.c (PFV): Remove.
 130         * lib/lbitset.c (PFV): Likewise.
 131         * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
 132         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
 133         decls.
 134         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
 135         (ebitset_vtable): Use them.
 136         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
 137         lbitset_xor): New functions.
 138         (lbitset_vtable): Use them.
 139
 140         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
 141         Declare.
 142
 143         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
 144         GCC warning.
 145         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
 146         Use offsetof, for simplicity.
 147
 148 2002-10-06  Paul Eggert  <eggert@twinsun.com>
 149
 150         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
 151         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
 152         <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
 153         which was inadvertently undone by the 2002-09-30 patch.
 154         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
 155         the same width as int.
 156
 157 2002-10-04  Paul Eggert  <eggert@twinsun.com>
 158
 159         Version 1.50.
 160
 161         * configure.ac (AC_INIT), NEWS: Increment version number.
 162
 163         * doc/bison.texinfo: Minor spelling, grammar, and white space
 164         fixes.
 165         (Symbols): Mention that any negative value returned from yylex
 166         signifies end-of-input.  Warn about negative chars.  Mention
 167         the portable Standard C character set.
 168
 169         The GNU coding standard says CFLAGS and YFLAGS are reserved
 170         for the installer to set.
 171         * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
 172         * src/Makefile.am (AM_CFLAGS): Likewise.
 173         (AM_YFLAGS): Renamed from YFLAGS.
 174
 175         Fix some MAX and MIN problems.
 176         * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
 177         * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
 178         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
 179         * src/reader.c (reader): Use it.
 180
 181         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
 182         POSIX 1003.1-2001 has removed fgrep.
 183
 184 2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
 185
 186         * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
 187         interpreted as signed.
 188         * lib/ebitset.c (ebitset_list): Fix bug.
 189
 190 2002-10-01  Paul Eggert  <eggert@twinsun.com>
 191
 192         More fixes for 64-bit hosts and large bitsets.
 193
 194         * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
 195         abitset_size, abitset_list, abitset_list_reverse, abitset_list):

 198         struct bitset_vtable.list, struct bitset_vtable.list_reverse,
 199         bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,
 200         bitset_count_): Likewise.
 201         * lib/bitset.h (bitset_iterator.num, bitset_iterator.i,
 202         bitset_first, bitset_last): Likewise.
 203         * lib/bitset_stats.c (bitset_stats_size, bitset_stats_list,
 204         bitset_stats_list_reverse, bitset_stats_size,
 205         bitset_stats_count, bitset_stats_list, bitset_stat_list_reverse):
 206         Likewise.
 207         * lib/bitsetv-print.c (bitsetv_matrix_dump): Likewise.
 208         * lib/bitsetv.c (bitsetv_alloc, bitsetv_create, bitsetv_free,

 230
 231         * lib/abitset.c (abitset_empty_p, abitset_not, abitset_equal_p,
 232         abitset_subset_p, abitset_disjoint_p, abitset_and,
 233         abitset_and_cmp, abitset_andn, abitset_andn_cmp, abitset_or,

 236         abitset_or_and, abitset_or_and_cmp):

 253         * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
 254         BITSET_SIZE_MAX): New macros.
 255         (BITSET_INDEX_MAX): Remove.  It wasn't right, since it assumed that
 256         sizeof (bitset_word) == sizeof (bitset_windex).  All uses changed
 257         to BITSET_WINDEX_MAX.
 258
 259         * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
 260         bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
 261         since we now return the bitset_bindex type (not int).

 266
 267         * lib/lbitset.c (lbitset_elt_find): Simplify windex calculation
 268         and avoid cast to unsigned.

 279         invocations.

 306         * lib/Makefile.am (libbison_a_SOURCES): No longer include

 374
 375 2002-09-04  Jim Meyering  <jim@meyering.net>
 376
 377         * data/yacc.c: Guard the declaration of yytoknum also with
 378         `#ifdef YYPRINT', so it is declared only when used.

 381
 382         * configure.in: Rename as...

 410         (yyreportParseError): Use size_t for yysize.
 411         (yy_yypstack): No longer nested inside yypstates, as nested
 412         functions are not portable.  Do not assume size_t is the
 413         same width as int.
 414         (yypstates): Do not assume that ptrdiff_t is the same width
 415         as int, and similarly for yyposn and YYINDEX.
 416
 417         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 418
 419         * lib/Makefile.am (INCLUDES): Do not include from the intl
 420         directory, which has been removed.
 421         * src/Makefile.am (INCLUDES): Likewise.

 442         portability to one's complement hosts!).
 443         * lib/ebitset.c (ebitset_op1): Likewise.
 444         * lib/lbitset.c (lbitset_op1): Likewise.
 445

 455
 456         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 457         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 458         check for void *.
 459
 460         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 461         size_t; the old version tried to do this but casted improperly.
 462         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 463         (bitset_test): Now returns int, not unsigned long.

 467         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 468         name locals "index", as it generates unnecessary warnings on some
 469         hosts that have an "index" function.
 470
 471         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 472         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
 473         they need translation.

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

 489         * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
 490
 491         * po/LINGUAS: Add pt_BR.
 492         * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
 493         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 494         lib/timevar.c.
 495         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 496         manual recommends.
 497         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 498
 499         * src/complain.c (strerror_r): Remove decl; not needed.
 500         (strerror): Use same pattern as ../lib/error.c.

 505
 506         * src/main.c (main): Cast result of bindtextdomain and textdomain
 507         to void, to avoid a GCC warning when --disable-nls is in effect.
 508
 509         * src/scan-gram.l: Use strings rather than escapes when possible,
 510         to minimize the number of warnings from xgettext.
 511         (handle_action_dollar, handle_action_at): Don't use isdigit,
 512         as it mishandles negative chars and it may not work as expected
 513         outside the C locale.
 514
 515         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 516         this is a GCC extension and is not portable to other compilers.
 517
 518         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 519         Do not include <ctype.h>; no longer needed.
 520         Do not include <malloc.h>; no longer needed (and generates
 521         warnings on OpenBSD 3.0).
 522
 523         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
 524         it's not portable.
 525
 526         * tests/regression.at: Do not use 'cc -c input.c -o input';
 527         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
 528
 529         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
 530         exit status as failure, not just exit status 1.  Sun C exits
 531         with status 2 sometimes.
 532
 533         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
 534         Use it for the two large tests.
 535

 537
 538         * src/conflicts.c (conflicts_output): Don't output rules never
 539         reduced here, since anyway that computation doesn't work.
 540         * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
 541         (rule_useless_p, rule_never_reduced_p): New.

 547         reduced to...
 548         (token_actions): here.
 549         * src/main.c (main): Make the parser before making the report, so
 550         that rules never reduced are computed.
 551         Call grammar_rules_never_reduced_report.
 552         * src/print.c (print_results): Report rules never reduced.
 553         * tests/conflicts.at, tests/reduce.at: Adjust.
 554
 555 2002-08-01  Akim Demaille  <akim@epita.fr>
 556
 557         Instead of attaching lookaheads and duplicating the rules being
 558         reduced by a state, attach the lookaheads to the reductions.
 559
 560         * src/state.h (state_t): Remove the `lookaheads',
 561         `lookaheads_rule' member.
 562         (reductions_t): Add a `lookaheads' member.

 564         * src/state.c (reductions_new): Initialize the lookaheads member
 565         to 0.
 566         (state_rule_lookaheads_print): Adjust.
 567         * src/state.h, src/state.c (state_reductions_find): New.

 569         (count_rr_conflicts): Adjust.

 573         (states_lookaheads_initialize): Merge into...
 574         (initialize_LA): this.
 575         (lalr_free): Adjust.
 576         * src/main.c (main): Don't free nullable and derives too early: it
 577         is used by --verbose.
 578         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
 579
 580 2002-08-01  Akim Demaille  <akim@epita.fr>
 581
 582         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
 583         `rule_number_t**'.
 584         (set_derives, free_derives): Rename as...
 585         (derives_compute, derives_free): this.
 586         Adjust all dependencies.

 590         * src/state.c (state_rule_lookaheads_print): Directly compare rule
 591         pointers, instead of their numbers.
 592         * src/main.c (main): Call nullable_free, and derives_free earlier,
 593         as they were lo longer used.
 594
 595 2002-08-01  Akim Demaille  <akim@epita.fr>
 596
 597         * lib/timevar.c (get_time): Include children time.
 598         * src/lalr.h (LA, LArule): Don't export them: used with the
 599         state_t.
 600         * src/lalr.c (LA, LArule): Static.
 601         * src/lalr.h, src/lalr.c (lalr_free): New.

 603         * src/tables.c (pack_vector): Check whether loc is >= to the
 604         table_size, not >.
 605         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
 606         (tables_generate): do it, since that's also it which allocates
 607         them.
 608         Don't free LA and LArule, main does.
 609
 610 2002-07-31  Akim Demaille  <akim@epita.fr>

 657         * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
 658         (long_options, short_options): --trace/-T takes an optional
 659         argument.
 660         Change all the uses of trace_flag to reflect the new flags.
 661         * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
 662
 663         Strengthen `stage' portability.
 664

 666         * configure.in: Use it.
 667         Don't check for malloc.h and sys/times.h.
 668         * src/system.h: Include them when appropriate.
 669         * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
 670         times and struct tms are available.
 671
 672 2002-07-30  Akim Demaille  <akim@epita.fr>
 673
 674         In verbose parse error message, don't report `error' as an
 675         expected token.
 676         * tests/actions.at (Printers and Destructors): Adjust.
 677         * tests/calc.at (Calculator $1): Adjust.
 678         * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose

 680         that state.
 681

 692 2002-07-30  Akim Demaille  <akim@epita.fr>
 693
 694         Report rules which are never reduced by the parser: those hidden
 695         by conflicts.
 696
 697         * src/LR0.c (save_reductions): Don't make the final state too
 698         different: save its reduction (accept) instead of having a state
 699         without any action (no shift or goto, no reduce).
 700         Note: the final state is now a ``regular'' state, i.e., the
 701         parsers now contain `reduce 0' as default reduction.
 702         Nevertheless, since they decide to `accept' when yystate =
 703         final_state, they still will not reduce rule 0.
 704         * src/print.c (print_actions, print_reduction): Adjust.
 705         * src/output.c (action_row): Track reduced rules.

 714         * configure.in: Look for malloc.h and sys/times.h.
 715         * src/main.c (stage): Adjust.
 716         Report only when trace_flag.
 717

 735         Set undeftoken's tag to "$undefined" instead of "$undefined.".
 736         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
 737         Adjust.
 738
 739 2002-07-29  Akim Demaille  <akim@epita.fr>
 740
 741         * src/reduce.c (reduce_grammar): When the language is empty,
 742         complain about the start symbol, not the axiom.
 743         Use its location.
 744         * tests/reduce.at (Empty Language): New.

 750         itself.

 752         token_translations instead of `0'.
 753         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
 754         visible here.
 755         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
 756         for the time being: %locations ought to provide it to yyerror.
 757
 758 2002-07-25  Akim Demaille  <akim@epita.fr>
 759
 760         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1829         grammar.
1830         Use more modest sizes, as for the time being the parser does not
1831         release memory, and therefore the process swallows a huge amount
1832         of memory.
1833
1834         * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the

1845         eccentricities.

1856
1857         * src/reader.c  (parse_action): Don't store directly into the
1858         rule's action member: return the action as a string.

1920
1921         Remove `%thong' support as it is undocumented, unused, duplicates
1922         `%token's job, and creates useless e-mail traffic with people who

2362         (pre_prologue_obstack, post_prologue_obstack): New.
2363         * src/reader.c (copy_definition): Add a parameter to specify the
2364         obstack to fill, instead of using attrs_obstack unconditionally.
2365         (read_declarations): Pass pre_prologue_obstack to copy_definition if
2366         `%union' has not yet been seen, pass post_prologue_obstack otherwise.

2370         * data/bison.simple: Remove unnecessary commentary and white
2371         space differences from 1_29-branch.
2372         Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
2373
2374         (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
2375         YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
2376         if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
2377         constructors or destructors.
2378
2379         (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.

2390
2391         * src/reduce.c (dump_grammar): Move to...
2392         * src/gram.h, src/gram.c (grammar_dump): here.
2393         Be sure to separate long item numbers.
2394         Don't read the members of a rule's prec if its nil.
2395
2396 2002-04-22  Akim Demaille  <akim@epita.fr>
2397
2398         * src/output.c (table_size, table_grow): New.
2399         (MAXTABLE): Remove, replace uses with table_size.
2400         (pack_vector): Instead of dying when the table is too big, grow it.
2401
2402 2002-04-22  Akim Demaille  <akim@epita.fr>
2403
2404         * data/bison.simple (yyr1): Its type is that of a token number.
2405         * data/bison.c++ (r1_): Likewise.

2409
2410         * src/reader.c (token_translations_init): 256 is now the default
2411         value for the error token, i.e., it will be assigned another
2412         number if the user assigned 256 to one of her tokens.
2413         (reader): Don't force 256 to error.
2414         * doc/bison.texinfo (Symbols): Adjust.
2415         * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
2416         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
2417         etc. instead of 10, 20, 30 (which was used to `jump' over error
2418         (256) and undefined (2)).
2419
2420 2002-04-22  Akim Demaille  <akim@epita.fr>
2421
2422         Propagate more token_number_t.

2425         (item_number_as_token_number): New.
2426         * src/output.c (GENERATE_OUTPUT_TABLE): New.
2427         Use it to create output_item_number_table and
2428         output_token_number_table.

2435
2436         * src/output.h, src/output.c (get_lines_number): Remove.
2437
2438 2002-04-19  Akim Demaille  <akim@epita.fr>

2440         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
2441         as Lex/Flex'.
2442         (Debugging): More details about enabling the debugging features.
2443         (Table of Symbols): Describe $$, $n, @$, and @n.
2444         Suggested by Tim Josling.
2445
2446 2002-04-19  Akim Demaille  <akim@epita.fr>
2447
2448         * doc/bison.texinfo: Remove the uses of the obsolete @refill.

2451
2452         * src/system.h: Rely on HAVE_LIMITS_H.
2453         Suggested by Paul Eggert.
2454
2455 2002-04-09  Akim Demaille  <akim@epita.fr>
2456
2457         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2458         full stderr, and strip it according to the bison options, instead
2459         of composing the error message from different bits.
2460         This makes it easier to check for several error messages.
2461         Adjust all the invocations.
2462         Add an invocation exercising the error token.
2463         Add an invocation demonstrating a stupid error message.
2464         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
2465         Adjust the tests.
2466         Error message are for stderr, not stdout.
2467
2468 2002-04-09  Akim Demaille  <akim@epita.fr>
2469
2470         * src/gram.h, src/gram.c (error_token_number): Remove, use
2471         errtoken->number.
2472         * src/reader.c (reader): Don't specify the user token number (2)
2473         for $undefined, as it uselessly prevents using it.
2474         * src/gram.h (token_number_t): Move to...
2475         * src/symtab.h: here.
2476         (state_t.number): Is a token_number_t.
2477         * src/print.c, src/reader.c: Use undeftoken->number instead of
2478         hard coded 2.
2479         (Even though this 2 is not the same as above: the number of the
2480         undeftoken remains being 2, it is its user token number which
2481         might not be 2).
2482         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2483         `user_token_number_max'.
2484         Output `undef_token_number'.
2485         * data/bison.simple, data/bison.c++: Use them.
2486         Be sure to map invalid yylex return values to
2487         `undef_token_number'.  This saves us from gratuitous SEGV.
2488
2489         * tests/conflicts.at (Solved SR Conflicts)
2490         (Unresolved SR Conflicts): Adjust.
2491         * tests/regression.at (Web2c Actions): Adjust.

2494
2495         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
2496         Adding #line.
2497         Remove the duplicate `typedefs'.
2498         (RhsNumberType): Fix the declaration and various other typos.
2499         Use __ofile__.
2500         * data/bison.simple: Use __ofile__.
2501         * src/scan-skel.l: Handle __ofile__.
2502
2503 2002-04-08  Akim Demaille  <akim@epita.fr>
2504
2505         * src/gram.h (item_number_t): New, the type of item numbers in
2506         RITEM.  Note that it must be able to code symbol numbers as
2507         positive number, and the negation of rule numbers as negative
2508         numbers.
2509         Adjust all dependencies (pretty many).
2510         * src/reduce.c (rule): Remove this `short *' pointer: use
2511         item_number_t.
2512         * src/system.h (MINSHORT, MAXSHORT): Remove.
2513         Include `limits.h'.
2514         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2515         (shortcpy): Remove.
2516         (MAXTABLE): Move to...
2517         * src/output.c (MAXTABLE): here.
2518         (prepare_rules): Use output_int_table to output rhs.
2519         * data/bison.simple, data/bison.c++: Adjust.
2520         * tests/torture.at (Big triangle): Move the limit from 254 to
2521         500.
2522         * tests/regression.at (Web2c Actions): Ajust.
2523
2524         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2525         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2526         passes, but produces negative #line number, once fixed, GCC is
2527         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2528         C), it passes.
2529         * src/state.h (state_h): Code input lines on ints, not shorts.
2530
2531 2002-04-08  Akim Demaille  <akim@epita.fr>
2532
2533         * src/reduce.c (reduce_grammar): First reduce the nonterminals,

2545         * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
2546         New.
2547         Use them to define yy_token_number_type/TokenNumberType.
2548         Use this type for yytranslate.
2549         * tests/torture.at (Big triangle): Push the limit from 124 to

2624         to the bucket giving the priority/associativity.
2625         Member `associativity' removed: useless.

2656
2657 2002-04-07  Akim Demaille  <akim@epita.fr>
2658
2659         Be sure never to walk through RITEMS, but use only data related to
2660         the rules themselves. RITEMS should be banished.
2661
2662         * src/output.c (output_token_translations): Rename as...
2663         (prepare_tokens): this.
2664         In addition to `translate', prepare the muscles `tname' and

2666         (output_rule_data): this.
2667         Remove, and move the remainder of its outputs into...
2668         (prepare_rules): this new routines, which also merges content from

2677
2678         * src/LR0.c (new_state): Display `nstates' as the name of the
2679         newly created state.
2680         Adjust to initialize first_state and last_state if needed.
2681         Be sure to distinguish the initial from the final state.
2682         (new_states): Create the itemset of the initial state, and use
2683         new_state.
2684         * src/closure.c (closure): Now that the initial state has its
2685         items properly set, there is no need for a special case when
2686         creating `ruleset'.
2687
2688         As a result, now the rule 0, reducing to $axiom, is visible in the
2689         outputs.  Adjust the test suite.

3030         causing more problems than it was curing, since it didn't work
3031         properly on some nonstandard C++ compilers.  This can wait

3049
3050 2002-02-13  Andreas Schwab  <schwab@suse.de>
3051
3052         * src/output.c (output_rule_data): Don't output NULL, it might
3053         not be defined yet.
3054
3055 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
3056
3057         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
3058         (Copyright notice): Update.
3059
3060 2002-02-11  Akim Demaille  <akim@epita.fr>
3061
3062         * tests/regression.at (%nonassoc and eof): Don't include
3063         nonportable headers.
3064
3065 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
3066
3067         * data/bison.c++: Correct error recovery.  Make the user able to
3068         initialize the starting location.
3069
3070 2002-02-07  Akim Demaille  <akim@epita.fr>
3071
3072         * tests/input.at: New.
3073
3074 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3075
3076         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
3077         more consistent when naming methods and variables.  Put preprocessor
3078         directives around tables only needed for debugging.
3079
3080 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3081
3082         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
3083         C++ parsers.
3084         (yy::b4_name::parse): Use print_.
3085
3086 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3087
3088         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
3089
3090 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3091
3092         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
3093         C++ parsers.
3094         (yy::b4_name::parse): Build verbose error messages, and use error_.
3095
3096 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3097
3098         * data/bison.c++: Fix m4 quoting in comments.
3099
3100 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3101
3102         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
3103         not expanded by m4.
3104
3105 2002-02-05  Akim Demaille  <akim@epita.fr>
3106
3107         * data/bison.c++: Adjust to the M4 back end.
3108         More is certainly needed.
3109
3110 2002-02-05  Akim Demaille  <akim@epita.fr>
3111
3112         Give a try to M4 as a back end.
3113
3114         * lib/readpipe.c: New, from wdiff.
3115         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
3116         BISON_HAIRY.
3117         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
3118         specific values.  Now it is m4 that performs the lookup.
3119         * src/parse-skel.y: Remove.
3120         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
3121         * src/output.c (actions_output, guards_output)
3122         (token_definitions_output): No longer keeps track of the output
3123         line number, hence remove the second argument.
3124         (guards_output): Check against the guard member of a rule, not the
3125         action member.
3126         Adjust callers.
3127         (output_skeleton): Don't look for the skeleton location, let m4 do
3128         that.
3129         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
3130         file will be used.
3131         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3132         (prepare): Given that for the time being changesyntax is not
3133         usable in M4, rename the muscles using `-' to `_'.
3134         Define `defines_flag', `output_parser_name' and `output_header_name'.
3135         * src/output.h (actions_output, guards_output)
3136         (token_definitions_output): Adjust prototypes.
3137         * src/scan-skel.l: Instead of scanning the skeletons, it now
3138         processes the output of m4: `__oline__' and `#output'.
3139         * data/bison.simple: Adjust to be used by M4(sugar).
3140         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3141         to date.
3142         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3143         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
3144         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
3145         shamelessly stolen from CVS Autoconf.
3146
3147 2002-02-05  Akim Demaille  <akim@epita.fr>
3148
3149         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
3150         * configure.in: Check for the declarations of free and malloc.
3151         * src/muscle_tab.c: Adjust.
3152
3153 2002-02-05  Akim Demaille  <akim@epita.fr>
3154
3155         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
3156         which have no values.
3157
3158 2002-02-05  Akim Demaille  <akim@epita.fr>
3159
3160         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
3161         * data/: here.
3162
3163 2002-01-29  Paul Eggert  <eggert@twinsun.com>
3164
3165         * src/bison.simple (YYSIZE_T): Do not define merely because
3166         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3167         On some platforms, <alloca.h> does not declare YYSTD (size_t).
3168
3169 2002-01-27  Akim Demaille  <akim@epita.fr>
3170
3171         Fix `%nonassoc and eof'.
3172
3173         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
3174         which were not properly copied!  Replace
3175         memcpy (res->errs, src->errs, src->nerrs);
3176         with
3177         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3178         !!!
3179         * tests/regression.at (%nonassoc and eof): Adjust to newest
3180         Autotest: `.' is not in the PATH.
3181
3182 2002-01-27  Akim Demaille  <akim@epita.fr>
3183
3184         * tests/sets.at (AT_EXTRACT_SETS): New.
3185         (Nullable): Use it.
3186         (Firsts): New.
3187
3188 2002-01-26  Akim Demaille  <akim@epita.fr>
3189
3190         * tests/actions.at, tests/calc.at, tests/headers.at,
3191         * tests/torture.at: Adjust to the newest Autotest which no longer
3192         forces `.' in the PATH.
3193
3194 2002-01-25  Akim Demaille  <akim@epita.fr>
3195
3196         * tests/regression.at (%nonassoc and eof): New.
3197         Suggested by Robert Anisko.
3198
3199 2002-01-24  Akim Demaille  <akim@epita.fr>
3200
3201         Bison dumps core when trying to complain about broken input files.
3202         Reported by Cris van Pelt.
3203
3204         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
3205         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
3206         into...
3207         (Invalid inputs): Strengthen: exercise parse_percent_token.
3208
3209 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
3210
3211         * src/Makefile.am: Add bison.c++.
3212         * src/bison.c++: New skeleton.
3213
3214 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
3215
3216         * po/it.po: New.
3217
3218 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
3219
3220         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
3221
3222 2002-01-20  Marc Autret  <marc@gnu.org>
3223
3224         * src/files.c (compute_output_file_names): Fix
3225
3226 2002-01-20  Marc Autret  <marc@gnu.org>
3227
3228         * tests/output.at: New test.
3229         * src/files.c (compute_base_names): Don't map extensions when
3230         the YACC flag is set, use defaults.
3231         Reported by Evgeny Stambulchik.
3232
3233 2002-01-20  Marc Autret  <marc@gnu.org>
3234
3235         * src/system.h: Need to define __attribute__ away for non-GCC
3236         compilers as well (i.e. the vendor C compiler).
3237         Suggested by Albert Chin-A-Young.
3238
3239 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
3240
3241         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3242         canonical definition.
3243         * src/system.h: Use the canonical definition for PARAMS (avoids
3244         a conflict with the macro from lib/hash.h).
3245
3246 2002-01-11  Akim Demaille  <akim@epita.fr>
3247
3248         * configure.in: Use AC_FUNC_STRNLEN.
3249         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3250
3251 2002-01-09  Akim Demaille  <akim@epita.fr>
3252
3253         * src/files.c, src/files.h (output_infix): New.
3254         (tab_extension): Remove.
3255         (compute_base_names): Compute the former, drop the latter.
3256         * src/output.c (prepare): Insert the muscles `output-infix', and
3257         `output-suffix'.
3258         * src/parse-skel.y (string, string.1): New.
3259         (section.header): Use it.
3260         (section.yacc): Remove.
3261         (prefix): Remove too.
3262         * src/scan-skel.l: Adjust.
3263         * src/bison.simple, src/bison.hairy: Adjust.
3264
3265 2002-01-09  Akim Demaille  <akim@epita.fr>
3266
3267         * configure.in (WERROR_CFLAGS): Compute it.
3268         * src/Makefile.am (CFLAGS): Pass it.
3269         * tests/atlocal.in (CFLAGS): Idem.
3270         * src/files.c: Fix a few warnings.
3271         (get_extension_index): Remove, unused.
3272
3273 2002-01-08  Akim Demaille  <akim@epita.fr>
3274
3275         * src/getargs.c (AS_FILE_NAME): New.
3276         (getargs): Use it to convert DOSish file names.
3277         * src/files.c (base_name): Rename as full_base_name to avoid
3278         clashes with `base_name ()'.
3279         (filename_split): New.
3280         (compute_base_names): N-th rewrite, using filename_split.
3281
3282 2002-01-08  Akim Demaille  <akim@epita.fr>
3283
3284         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3285         New, stolen from the Fileutils 4.1.
3286         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3287         * configure.in: Check for the presence of memrchr, and of its
3288         prototype.
3289
3290 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3291
3292         * lib/hash.h (__P): Added definition for this macro.
3293         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3294         BUILT_SOURCES, to ensure they are generated first.
3295         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3296         %error-verbose to allow bootstrapping with bison 1.30x.
3297
3298 2002-01-06  Akim Demaille  <akim@epita.fr>
3299
3300         * src/reader.c (parse_braces): Don't fetch the next char, the
3301         convention is to fetch on entry.
3302         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3303         'switch' without a following semicolon.
3304         * tests/regression.at (braces parsing): New.
3305
3306 2002-01-06  Akim Demaille  <akim@epita.fr>
3307
3308         Bison is dead wrong in its RR conflict reports.
3309
3310         * tests/torture.at (GNU Cim Grammar): New.
3311         * src/conflicts.c (count_rr_conflicts): Fix.
3312
3313 2002-01-06  Akim Demaille  <akim@epita.fr>
3314
3315         Creating package.m4 from configure.ac causes too many problems.
3316
3317         * tests/Makefile.am (package.m4): Create it by hand,
3318         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3319
3320 2002-01-06  Akim Demaille  <akim@epita.fr>
3321
3322         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3323         skeleton.h.
3324
3325 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3326
3327         * doc/bison.texinfo (Debugging):
3328         Remove YYSTDERR; it's no longer defined or used.
3329         Also, s/cstdio.h/cstdio/.
3330
3331 2002-01-03  Akim Demaille  <akim@epita.fr>
3332
3333         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3334
3335 2002-01-03  Akim Demaille  <akim@epita.fr>
3336
3337         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3338         tracing code to --trace, wait for a better --trace option, with
3339         args.
3340
3341 2002-01-03  Akim Demaille  <akim@epita.fr>
3342
3343         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3344         The ISO C++ standard is extremely clear about it: stderr is
3345         considered a macro, not a regular symbol (see table 94 `Header
3346         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3347         Therefore std:: does not apply to it.  It still does with fprintf.
3348         Also, s/cstdio.h/cstdio/.
3349
3350 2002-01-03  Akim Demaille  <akim@epita.fr>
3351
3352         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3353         for non system headers.
3354
3355 2002-01-02  Akim Demaille  <akim@epita.fr>
3356
3357         Equip the skeleton chain with location tracking, runtime trace,
3358         pure parser and scanner.
3359
3360         * src/parse-skel.y: Request a pure parser, locations, and prefix
3361         renaming.
3362         (%union): Having several members with the same type does not help
3363         type mismatches, simplify.
3364         (YYPRINT, yyprint): New.
3365         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3366         (skel_error): this.
3367         Handle locations.
3368         * src/scan-skel.l: Adjust to these changes.
3369         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3370         (LOCATION_PRINT, skel_control_t): New.
3371
3372 2001-12-30  Akim Demaille  <akim@epita.fr>
3373
3374         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3375         replace `gb' with BLANKS.
3376         * src/scan-skel.l: Adjust.
3377
3378 2001-12-30  Akim Demaille  <akim@epita.fr>
3379
3380         * src/system.h: We don't need nor want bcopy.
3381         Throw away MS-DOS crap: we don't need getpid.
3382         * configure.in: We don't need strndup.  It was even causing
3383         problems: because Flex includes the headers *before* us,
3384         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3385         not visible.
3386         * lib/xstrndup.c: New.
3387         * src/scan-skel.l: Use it.
3388         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3389         * src/parse-skel.y: Use %directives instead of #defines.
3390
3391 2001-12-30  Akim Demaille  <akim@epita.fr>
3392
3393         * src/skeleton.h: New.
3394         * src/output.c (output_parser, output_master_parser): Remove, dead
3395         code.
3396         * src/output.h (get_lines_number, actions_output, guards_output)
3397         (token_definitions_output): Prototype them.
3398         * src/parse-skel.y: Add the license notice.
3399         Include output.h and skeleton.h.
3400         (process_skeleton): Returns void, and takes a single parameter.
3401         * src/scan-skel.l: Add the license notice.
3402         Include skeleton.h.
3403         Don't use %option yylineno: it seems that then Flex imagines
3404         REJECT has been used, and therefore it won't reallocate its
3405         buffers (which makes no other sense to me than a bug).  It results
3406         in warnings for `unused: yy_flex_realloc'.

3409
3410         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3411         (MUSCLE_INSERT_PREFIX): ...to there.
3412         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3413         (MUSCLE_INSERT_PREFIX): Move from here...
3414
3415         * src/bison.hairy: Add a section directive.  Put braces around muscle
3416         names.  This parser skeleton is still broken, but Bison should not
3417         choke on a bad muscle 'syntax'.
3418         * src/bison.simple: Add a section directive.  Put braces around muscle
3419         names.
3420
3421         * src/files.h (strsuffix, stringappend): Add declarations.
3422         (tab_extension): Add declaration.
3423         (short_base_name): Add declaration.
3424
3425         * src/files.c (strsuffix, stringappend): No longer static.  These
3426         functions are used in the skeleton parser.
3427         (tab_extension): New.
3428         (compute_base_names): Use the computations done in this function
3429         to guess if the generated parsers should have '.tab' in their
3430         names.
3431         (short_base_name): No longer static.
3432
3433         * src/output.c (output_skeleton): New.
3434         (output): Disable call to output_master_parser, and give a try to
3435         a new skeleton handling system.
3436         (guards_output, actions_output): No longer static.
3437         (token_definitions_output, get_lines_number): No longer static.
3438
3439         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3440
3441         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3442         parse-skel.y.
3443
3444         * src/parse-skel.y: New file.
3445         * src/scan-skel.l: New file.

3447 2001-12-29  Akim Demaille  <akim@epita.fr>
3448
3449         %name-prefix is broken.
3450
3451         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3452         Adjust all dependencies.
3453         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3454         %name-prefix.
3455
3456         Renaming yylval but not yylloc is not consistent.  Now we do.
3457
3458         * src/bison.simple: Prefix yylloc if used.
3459         * doc/bison.texinfo (Decl Summary): Document that.
3460
3461 2001-12-29  Akim Demaille  <akim@epita.fr>
3462
3463         * doc/bison.texinfo: Promote `%long-directive' over
3464         `%long_directive'.
3465         Remove all references to fixed-output-files, yacc is enough.
3466
3467 2001-12-29  Akim Demaille  <akim@epita.fr>
3468
3469         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3470         user prologue.  These are defaults.
3471         * tests/actions.at (Mid-rule actions): Make sure the user can
3472         define YYDEBUG and YYERROR_VERBOSE.
3473
3474 2001-12-29  Akim Demaille  <akim@epita.fr>
3475
3476         * src/output.c (header_output): Don't forget to export YYLTYPE and
3477         yylloc.
3478         * tests/headers.at (export YYLTYPE): New, make sure it does.
3479         * tests/regression.at (%union and --defines, Invalid CPP headers):
3480         Move to...
3481         * tests/headers.at: here.
3482
3483 2001-12-29  Akim Demaille  <akim@epita.fr>
3484
3485         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3486

3488
3489         * tests/actions.at (Mid-rule actions): Output on a single line

3492 2001-12-29  Akim Demaille  <akim@epita.fr>
3493
3494         * doc/bison.texinfo: Formatting changes.
3495
3496 2001-12-29  Akim Demaille  <akim@epita.fr>
3497
3498         Don't store the token defs in a muscle, just be ready to output it
3499         on command.  Now possible via `symbols'.  Fixes a memory leak.
3500
3501         * src/output.c (token_definitions_output): New.
3502         (output_parser, header_output): Use it.
3503         * src/reader.c (symbols_save): Remove.
3504
3505 2001-12-29  Akim Demaille  <akim@epita.fr>
3506
3507         * src/bison.simple: Do not provide a default for YYSTYPE and
3508         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3509         default.
3510
3511 2001-12-29  Akim Demaille  <akim@epita.fr>
3512
3513         Mid-rule actions are simply... ignored!
3514
3515         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3516         the empty-rule associated to the dummy symbol, not to the host
3517         rule.
3518         * tests/actions.at (Mid-rule actions): New.
3519
3520 2001-12-29  Akim Demaille  <akim@epita.fr>
3521
3522         Memory leak.

3525
3526 2001-12-29  Akim Demaille  <akim@epita.fr>
3527
3528         Memory leak.
3529
3530         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3531         since it allocates it for each state, although only one is needed.
3532         (allocate_storage): Do it here.
3533
3534 2001-12-29  Akim Demaille  <akim@epita.fr>
3535
3536         * src/options.h, src/options.c (create_long_option_table): Rename
3537         as...

3539         (percent_table): Remove, unused,
3540         * src/getargs.c (getargs): Adjust.

3549
3550         * src/lalr.c (build_relations): Rename `states' as `states1'.
3551         Sorry, I don't understand exactly what it is, no better name...
3552
3553 2001-12-29  Akim Demaille  <akim@epita.fr>

3559
3560 2001-12-29  Akim Demaille  <akim@epita.fr>
3561
3562         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3563         ago.
3564
3565 2001-12-29  Akim Demaille  <akim@epita.fr>
3566
3567         * src/reader.c, src/reader.h (user_toknums): Remove.
3568         Adjust all users to use symbols[i]->user_token_number.
3569
3570 2001-12-29  Akim Demaille  <akim@epita.fr>
3571
3572         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3573         Adjust all users to use symbols[i]->prec or ->assoc.
3574
3575 2001-12-29  Akim Demaille  <akim@epita.fr>
3576
3577         * src/reader.c, src/reader.h (tags): Remove.

3579
3580 2001-12-29  Akim Demaille  <akim@epita.fr>
3581
3582         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3583         and rule_table.
3584         * src/reader.c (packsymbols): Fill this table.
3585         Drop sprec.
3586         * src/conflicts.c (resolve_sr_conflict): Adjust.
3587         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3588         single table.
3589         Use symbols[i]->tag instead of tags[i].
3590
3591 2001-12-29  Akim Demaille  <akim@epita.fr>
3592
3593         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3594         In addition, put a comment in there, to replace...
3595         * tests/regression.at (%union and C comments): Remove.
3596
3597 2001-12-29  Akim Demaille  <akim@epita.fr>
3598
3599         * tests/regression.at (Web2c Actions): Blindly move the actual
3600         output as expected output.  The contents *seem* right to me, but I
3601         can't pretend reading perfectly parser tables...  Nonetheless, all
3602         the other tests pass correctly, the table look OK, even though the
3603         presence of `$axiom' is to be noted: AFAICS it is useless (but
3604         harmless).
3605
3606 2001-12-29  Akim Demaille  <akim@epita.fr>
3607
3608         * src/reader.c (readgram): Don't add the rule 0 if there were no
3609         rules read.  In other words, add it _after_ having performed
3610         grammar sanity checks.
3611         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3612
3613 2001-12-29  Akim Demaille  <akim@epita.fr>
3614
3615         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3616         visible, and some states have now a different number.
3617
3618 2001-12-29  Akim Demaille  <akim@epita.fr>
3619
3620         * src/reader.c (readgram): Bind the initial rule's lineno to that
3621         of the first rule.
3622         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3623         (Solved SR Conflicts): Adjust rule 0's line number.
3624
3625 2001-12-29  Akim Demaille  <akim@epita.fr>
3626
3627         Fix the `GAWK Grammar' failure.
3628
3629         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3630         the reductions of the first state which was mistakenly confused
3631         with the final state because precisely final_state was initialized
3632         to 0.
3633         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3634         now noticed by Bison.
3635         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3636         have a reduction on $default.
3637
3638 2001-12-29  Akim Demaille  <akim@epita.fr>
3639
3640         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3641         rule line numbers.
3642         * src/closure.c (print_closure): Likewise.
3643         * src/derives.c (print_derives): Likewise.
3644         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3645         now.
3646
3647 2001-12-29  Akim Demaille  <akim@epita.fr>
3648
3649         * src/lalr.c (lookaheads_print): New.
3650         (lalr): Call it when --trace-flag.
3651         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3652         are dumped.
3653
3654 2001-12-29  Akim Demaille  <akim@epita.fr>
3655
3656         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3657         when walking through ritem, even via rule->rhs.
3658         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3659         (useful_production, useless_nonterminals): Likewise.
3660         (reduce_grammar_tables): Likewise, plus update nritems.
3661         * src/nullable.c (set_nullable): Likewise.
3662         * src/lalr.c (build_relations): Likewise.
3663         * tests/sets.at (Nullable): Adjust.
3664         Fortunately, now, the $axiom is no longer nullable.
3665
3666 2001-12-29  Akim Demaille  <akim@epita.fr>
3667
3668         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3669         the 0-sentinel.
3670         * src/gram.c (ritem_longest_rhs): Likewise.
3671         * src/reduce.c (nonterminals_reduce): Likewise.

3676 2001-12-29  Akim Demaille  <akim@epita.fr>
3677
3678         * src/output.c: Comment changes.
3679
3680 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3681
3682         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3683         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3684         Sparc, as they were causing more porting problems than the
3685         (minor) performance improvement was worth.
3686
3687         Also, catch up with 1.31's YYSTD.
3688
3689 2001-12-27  Akim Demaille  <akim@epita.fr>
3690
3691         * src/output.c (output_gram): Rely on nritems, not the
3692         0-sentinel.  See below.
3693         Use -1 as separator, not 0.
3694         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3695         Rely on -1 as separator in yyrhs, instead of 0.
3696         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3697         twice `Now at end of input', therefore there are two lines less to
3698         expect.
3699
3700 2001-12-27  Akim Demaille  <akim@epita.fr>
3701
3702         * tests/regression.at (Unresolved SR Conflicts):
3703         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3704         below.
3705
3706 2001-12-27  Akim Demaille  <akim@epita.fr>
3707
3708         * src/LR0.c (new_state): Recognize the final state by the fact it
3709         is reached by eoftoken.
3710         (insert_start_shifting_state, insert_eof_shifting_state)
3711         (insert_accepting_state, augment_automaton): Remove, since now
3712         these states are automatically computed from the initial state.
3713         (generate_states): Adjust.
3714         * src/print.c: When reporting a rule number to the user, substract
3715         1, so that the axiom rule is rule 0, and the first user rule is 1.
3716         * src/reduce.c: Likewise.
3717         * src/print_graph.c (print_core): For the time being, just as for
3718         the report, depend upon --trace-flags to dump the full set of
3719         items.
3720         * src/reader.c (readgram): Once the grammar read, insert the rule
3721         0: `$axiom: START-SYMBOL $'.
3722         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3723         number of the states has changed (the final state is no longer
3724         necessarily the last), catch up.
3725
3726 2001-12-27  Akim Demaille  <akim@epita.fr>
3727
3728         Try to make the use of the eoftoken valid.  Given that its value
3729         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3730         is used instead of > 0 where appropriate, (ii), depend upon nritems
3731         instead of the 0-sentinel.
3732
3733         * src/gram.h, src/gram.c (nritems): New.
3734         Expected to be duplication of nitems, but for the time being...
3735         * src/reader.c (packgram): Assert nritems and nitems are equal.
3736         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3737         * src/closure.c (print_closure, print_fderives): Likewise.
3738         * src/gram.c (ritem_print): Likewise.
3739         * src/print.c (print_core, print_grammar): Likewise.
3740         * src/print_graph.c: Likewise.
3741
3742 2001-12-27  Akim Demaille  <akim@epita.fr>
3743
3744         * src/main.c (main): If there are complains after grammar
3745         reductions, then output the report anyway if requested, then die.
3746         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3747         * src/reader.c (eoftoken): New.
3748         (parse_token_decl): If the token being defined has value `0', it
3749         is the eoftoken.
3750         (packsymbols): No longer hack `tags' to insert `$' by hand.
3751         Be sure to preserve the value of the eoftoken.
3752         (reader): Make sure eoftoken is defined.
3753         Initialize nsyms to 0: now eoftoken is created just like the others.
3754         * src/print.c (print_grammar): Don't special case the eof token.
3755         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3756         lie anyway, albeit pleasant.
3757         * tests/calc.at: Exercise error messages with eoftoken.
3758         Change the grammar so that empty input is invalid.
3759         Adjust expectations.
3760         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3761
3762 2001-12-27  Akim Demaille  <akim@epita.fr>
3763
3764         * configure.in: Check the protos of strchr ans strspn.
3765         Replace strchr if needed.
3766         * src/system.h: Provide the protos of strchr, strspn and memchr if
3767         missing.
3768         * lib/strchr.c: New.
3769         * src/reader.c (symbols_save): Use strchr.
3770
3771 2001-12-27  Akim Demaille  <akim@epita.fr>
3772
3773         * src/print.c, src/print_graph.c (escape): New.
3774         Use it to quote the TAGS outputs.
3775         * src/print_graph.c (print_state): Now errors are in red, and
3776         reductions in green.
3777         Prefer high to wide: output the state number on a line of its own.
3778
3779 2001-12-27  Akim Demaille  <akim@epita.fr>
3780
3781         * src/state.h, src/state.c (reductions_new): New.
3782         * src/LR0.c (set_state_table): Let all the states have a
3783         `reductions', even if reduced to 0.
3784         (save_reductions): Adjust.
3785         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
3786         * src/print.c (print_reductions, print_actions): Adjust.
3787         * src/output.c (action_row): Adjust.
3788
3789 2001-12-27  Akim Demaille  <akim@epita.fr>
3790
3791         * src/state.h, src/state.c (errs_new, errs_dup): New.
3792         * src/LR0.c (set_state_table): Let all the states have an errs,
3793         even if reduced to 0.
3794         * src/print.c (print_errs, print_reductions): Adjust.
3795         * src/output.c (output_actions, action_row): Adjust.
3796         * src/conflicts.c (resolve_sr_conflict): Adjust.
3797
3798 2001-12-27  Akim Demaille  <akim@epita.fr>
3799
3800         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3801
3802 2001-12-27  Akim Demaille  <akim@epita.fr>
3803
3804         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3805         * src/print.c: here.
3806         (lookaheadset, shiftset): New, used as additional storage by
3807         print_reductions.
3808         (print_results): Adjust.
3809         (print_shifts, print_gotos, print_errs): New, extracted from...
3810         (print_actions): here.
3811         * src/print_graph.c (print_actions): Remove dead code.
3812
3813 2001-12-27  Akim Demaille  <akim@epita.fr>
3814
3815         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3816         `$n' and `@n'.
3817
3818 2001-12-27  Akim Demaille  <akim@epita.fr>
3819
3820         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3821         (build_relations): Adjust.
3822
3823 2001-12-27  Akim Demaille  <akim@epita.fr>
3824
3825         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3826         duplication.
3827
3828 2001-12-27  Akim Demaille  <akim@epita.fr>
3829
3830         * src/reader.c (packgram): Catch nitems overflows.
3831
3832 2001-12-27  Akim Demaille  <akim@epita.fr>
3833
3834         * src/files.c, src/files.h (guard_obstack): Remove.
3835         * src/output.c (output): Adjust.
3836         * src/reader.c (parse_braces): New, factoring...
3837         (copy_action, copy_guard): these two which are renamed as...
3838         (parse_action, parse_guard): these.
3839         As a voluntary consequence, using braces around guards is now
3840         mandatory.
3841
3842 2001-12-27  Akim Demaille  <akim@epita.fr>
3843
3844         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3845         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3846         members.
3847         (symbol_list_new): Adjust.
3848         (copy_action): action_line is the first line, not the last.
3849         (copy_guard): Just as for actions, store the `action' only, not
3850         the switch/case/break flesh.
3851         Don't parse the user action that might follow the guard, let...
3852         (readgram): do it, i.e., now, there can be an action after a
3853         guard.
3854         In other words the guard is just explicitly optional.
3855         (packgram): Adjust.
3856         * src/output.c (guards_output): New.
3857         (output_parser): Call it when needed.
3858         (output): Also free the guard and attrs obstacks.
3859         * src/files.c, src/files.h (obstack_save): Remove.
3860         (output_files): Remove.
3861         As a result, if one needs the former `.act' file, using an
3862         appropriate skeleton which requires actions and guards is now
3863         required.
3864         * src/main.c (main): Adjust.
3865         * tests/semantic.at: New.
3866         * tests/regression.at: Use `input.y' as input file name.
3867         Avoid 8+3 problems by requiring input.c when the test needs the
3868         parser.
3869
3870 2001-12-27  Akim Demaille  <akim@epita.fr>
3871
3872         * src/reader.c (symbol_list_new): Be sure to initialize all the
3873         fields.
3874
3875 2001-12-27  Akim Demaille  <akim@epita.fr>
3876
3877         All the hacks using a final pseudo state are now useless.
3878
3879         * src/LR0.c (set_state_table): state_table holds exactly nstates.
3880         * src/lalr.c (nLA): New.
3881         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3882         instead of lookaheadsp from the pseudo state (nstate + 1).
3883
3884 2001-12-27  Akim Demaille  <akim@epita.fr>
3885
3886         * src/output.c (action_row, token_actions): Use a state_t instead
3887         of a integer, and nlookaheads instead of the following state's
3888         lookaheadsp.
3889
3890 2001-12-27  Akim Demaille  <akim@epita.fr>
3891
3892         * src/conflicts.c (log_resolution, flush_shift)
3893         (resolve_sr_conflict, set_conflicts, solve_conflicts)
3894         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3895         (conflicts_print, print_reductions): Use a state_t instead of an
3896         integer when referring to a state.
3897         As much as possible, depend upon nlookaheads, instead of the
3898         `lookaheadsp' member of the following state (since lookaheads of
3899         successive states are successive, the difference between state n + 1
3900         and n served as the number of lookaheads for state n).
3901         * src/lalr.c (add_lookback_edge): Likewise.
3902         * src/print.c (print_core, print_actions, print_state)
3903         (print_results): Likewise.
3904         * src/print_graph.c (print_core, print_actions, print_state)
3905         (print_graph): Likewise.
3906         * src/conflicts.h: Adjust.
3907
3908 2001-12-27  Akim Demaille  <akim@epita.fr>
3909
3910         * src/bison.hairy: Formatting/comment changes.
3911         ANSIfy.
3912         Remove `register' indications.
3913         Add plenty of `static'.
3914
3915 2001-12-27  Akim Demaille  <akim@epita.fr>
3916
3917         * src/output.c (prepare): Drop the muscle `ntbase' which
3918         duplicates ntokens.
3919         * src/bison.simple: Formatting/comment changes.
3920         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3921         is an undocumented synonym.
3922
3923 2001-12-22  Akim Demaille  <akim@epita.fr>
3924
3925         * src/output.c (output_table_data): Change the prototype to use
3926         `int' for array ranges: some invocations do pass an int, not a
3927         short.
3928         Reported by Wayne Green.

3932         Some actions of web2c.y are improperly triggered.
3933         Reported by Mike Castle.
3934
3935         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
3936         * tests/regression.at (Web2c): Rename as...
3937         (Web2c Report): this.
3938         (Web2c Actions): New.
3939
3940 2001-12-22  Akim Demaille  <akim@epita.fr>
3941
3942         Reductions in web2c.y are improperly reported.
3943         Reported by Mike Castle.
3944
3945         * src/conflicts.c (print_reductions): Fix.
3946         * tests/regression.at (Web2c): New.
3947
3948 2001-12-18  Akim Demaille  <akim@epita.fr>
3949
3950         Some host fail on `assert (!"foo")', which expands to
3951         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3952         Reported by Nelson Beebee.
3953
3954         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3955         `#define it_succeeded 0' and `assert (it_succeeded)'.
3956
3957 2001-12-17  Marc Autret  <autret_m@epita.fr>
3958
3959         * src/bison.simple: Don't hard code the skeleton line and filename.
3960         * src/output.c (output_parser): Rename 'line' as 'output_line'.
3961         New line counter 'skeleton_line' (skeleton-line muscle).
3962
3963 2001-12-17  Paul Eggert  <eggert@twinsun.com>
3964
3965         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3966         YYDEBUG must be defined to a nonzero value.
3967
3968         * src/bison.simple (yytname): Do not assume that the user defines
3969         YYDEBUG to a properly parenthesized expression.
3970
3971 2001-12-17  Akim Demaille  <akim@epita.fr>
3972
3973         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3974         nlookaheads is a new member.
3975         Adjust all users.
3976         * src/lalr.h (nlookaheads): Remove this orphan declaration.
3977         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
3978         state.

3981
3982         * src/files.h, src/files.c (open_files, close_files): Remove.
3983         * src/main.c (main): Don't open/close files, nor invoke lex_free,
3984         let...
3985         * src/reader.c (reader): Do it.
3986
3987 2001-12-17  Akim Demaille  <akim@epita.fr>
3988
3989         * src/conflicts.c (print_reductions): Formatting changes.

3992

3997 2001-12-17  Akim Demaille  <akim@epita.fr>
3998
3999         * src/output.c (output_obstack): Be static and rename as...
4000         (format_obstack): this, to avoid any confusion with files.c's
4001         output_obstack.
4002         * src/reader.h (muscle_obstack): Move to...
4003         * src/output.h: here, since it's defined in output.c.
4004
4005 2001-12-17  Akim Demaille  <akim@epita.fr>
4006
4007         * src/output.c (action_row, save_column, default_goto)
4008         (sort_actions, matching_state, pack_vector): Better variable
4009         locality.
4010
4011 2001-12-17  Akim Demaille  <akim@epita.fr>
4012

4016
4017         * src/files.c (output_files): Free the output_obstack.

4022
4023 2001-12-16  Marc Autret  <autret_m@epita.fr>
4024
4025         * src/output.c (actions_output): Fix. When we use %no-lines,
4026         there is one less line per action.
4027
4028 2001-12-16  Marc Autret  <autret_m@epita.fr>
4029
4030         * src/bison.simple: Remove a useless #line directive.
4031         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4032         * src/output.c (get_lines_number): New.
4033         (output_parser): Adjust, now takes care about the lines of a
4034         output muscles.
4035         Fix line numbering.
4036         (actions_output): Computes the number of lines taken by actions.
4037         (output_master_parser): Insert new skeleton which is the name of
4038         the output parser file name.
4039
4040 2001-12-15  Marc Autret  <autret_m@epita.fr>
4041
4042         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.

4044 2001-12-15  Marc Autret  <autret_m@epita.fr>
4045
4046         * src/output.c (output_gram): Keep track of the hairy one.
4047
4048 2001-12-15  Akim Demaille  <akim@epita.fr>
4049
4050         Make `make distcheck' work.
4051
4052         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4053         system.h which uses libgettext.h.
4054
4055 2001-12-15  Akim Demaille  <akim@epita.fr>
4056
4057         * src/nullable.c (set_nullable): Useless rules must be skipped,
4058         otherwise, since we range over their symbols, we might look at a
4059         nonterminal which no longer ``exists'', i.e., it is not counted in
4060         `nvars', hence we overflow our arrays.
4061
4062 2001-12-15  Akim Demaille  <akim@epita.fr>
4063
4064         The header can also be produced directly, without any obstack!
4065         Yahoo!
4066
4067         * src/files.c, src/files.h (defines_obstack): Remove.
4068         (compute_header_macro): Global.
4069         (defines_obstack_save): Remove.
4070         * src/reader.c (parse_union_decl): No longer output to
4071         defines_obstack: its content can be found in the `stype' muscle
4072         anyway.
4073         (output_token_translations): Merge into...
4074         (symbols_output): this.

4080
4081 2001-12-15  Akim Demaille  <akim@epita.fr>
4082
4083         * src/reader.c (parse_union_decl): Instead of handling two obstack
4084         simultaneously, use one to define the `stype' muscle, and use the
4085         value of the latter to fill defines_obstack.
4086         (copy_comment): Remove.
4087         (copy_comment2): Work for a single obstack.
4088         Rename as...
4089         (copy_comment): this.

4095
4096 2001-12-15  Akim Demaille  <akim@epita.fr>
4097
4098         Still making progress in separating Bison into (i) input, (ii)
4099         process, (iii) output: now we can directly output the parser file
4100         without using table_obstack at all.
4101
4102         * src/files.c, src/files.h (table_obstack): Bye bye.
4103         (parser_file_name): New.
4104         * src/files.c (compute_output_file_names): Compute it.
4105         * src/output.c (actions_output, output_parser)
4106         (output_master_parser): To a file instead of an obstack.
4107
4108 2001-12-15  Akim Demaille  <akim@epita.fr>
4109
4110         Attach actions to rules, instead of pre-outputting them to
4111         actions_obstack.
4112
4113         * src/gram.h (rule_t): action and action_line are new members.
4114         * src/reader.c (symbol_list): Likewise.
4115         (copy_action): Save the actions within the rule.
4116         (packgram): Save them in rule_table.
4117         * src/output.c (actions_output): New.
4118         (output_parser): Use it on `%%actions'.
4119         (output_rule_data): Don't free rule_table.
4120         (output): Do it.
4121         (prepare): Don't save the `action' muscle.
4122         * src/bison.simple: s/%%action/%%actions/.
4123
4124 2001-12-15  Akim Demaille  <akim@epita.fr>
4125
4126         * src/reader.c (copy_action): When --yacc, don't append a `;'
4127         to the user action: let it fail if lacking.
4128         Suggested by Arnold Robbins and Tom Tromey.
4129
4130 2001-12-14  Akim Demaille  <akim@epita.fr>
4131
4132         * src/lex.c (literalchar): Simply return the char you decoded, non
4133         longer mess around with obstacks and int pointers.
4134         Adjust all callers.
4135
4136 2001-12-14  Akim Demaille  <akim@epita.fr>
4137
4138         * src/lex.c (literalchar): Don't escape the special characters,
4139         just decode them, and keep them as char (before, eol was output as
4140         the 2 char string `\n' etc.).
4141         * src/output.c (output_rule_data): Use quotearg to output the
4142         token strings.
4143
4144 2001-12-13  Paul Eggert  <eggert@twinsun.com>
4145
4146         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4147         Do not infringe on the global user namespace when using C++.
4148         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4149         All uses of `fprintf' and `stderr' changed.
4150
4151         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4152
4153 2001-12-13  Akim Demaille  <akim@epita.fr>
4154
4155         The computation of nullable is broken: it doesn't handle empty
4156         RHS's properly.
4157
4158         * tests/torture.at (GNU AWK Grammar): New.
4159         * tests/sets.at (Nullable): New.
4160         * src/nullable.c (set_nullable): Instead of blindly looping over
4161         `ritems', loop over the rules, and then over their rhs's.
4162
4163         Work around Autotest bugs.
4164
4165         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4166         frame, because Autotest understand lines starting with a `+' as
4167         traces from the shell.  Then, they are not processed properly.
4168         Admittedly an Autotest bug, but we don't have time to wait for
4169         Autotest to catch up.
4170         * tests/regression.at (Broken Closure): Adjust to the new table
4171         frames.
4172         Move to...
4173         * tests/sets.at: here.
4174
4175 2001-12-13  Akim Demaille  <akim@epita.fr>
4176
4177         * src/closure.c (closure): Use nrules instead of playing tricks
4178         with BITS_PER_WORD.
4179
4180 2001-12-13  Akim Demaille  <akim@epita.fr>
4181
4182         * src/print.c (print_actions): Output the handling of `$' as the
4183         traces do: shifting the token EOF.  Before EOF was treated as a
4184         nonterminal.
4185         * tests/regression.at: Adjust some tests.
4186         * src/print_graph.c (print_core): Complete the set of items via
4187         closure.  The next-to-final and final states are still unsatisfying,
4188         but that's to be addressed elsewhere.
4189         No longer output the rule numbers, but do output the state number.
4190         A single loop for the shifts + gotos is enough, but picked a
4191         distinct color for each.
4192         (print_graph): Initialize and finalize closure.
4193
4194 2001-12-13  Akim Demaille  <akim@epita.fr>
4195
4196         * src/reader.c (readgram): Remove dead code, an strip useless
4197         braces.
4198         (get_type): Remove, unused.
4199
4200 2001-12-12  Akim Demaille  <akim@epita.fr>
4201
4202         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4203         on that of lib/error.c.
4204
4205 2001-12-12  Akim Demaille  <akim@epita.fr>
4206
4207         Some hosts don't like `/' in includes.
4208
4209         * src/system.h: Include libgettext.h without qualifying the path.
4210         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4211         $(top_srcdir).
4212
4213 2001-12-11  Marc Autret  <autret_m@epita.fr>
4214
4215         * src/output.c (output_parser): Remove useless muscle.
4216
4217 2001-12-11  Marc Autret  <autret_m@epita.fr>
4218
4219         * src/bison.simple: Remove #line just before %%epilogue. It
4220         is now handled in ...
4221         * src/reader.c (read_additionnal_code): Add the output of a
4222         #line for the epilogue.
4223
4224 2001-12-10  Marc Autret  <autret_m@epita.fr>
4225
4226         * src/reader.c (copy_definition): Re-use CPP-outed code which
4227         replace precedent remove.
4228         * src/bison.simple: Remove #line before %%prologue because
4229         %%input-line is wrong at this time.
4230
4231 2001-12-10  Marc Autret  <autret_m@epita.fr>
4232
4233         * src/reader.c (symbols_output): Clean up.
4234         * src/output.c (output_gram, output): Clean up.
4235
4236 2001-12-10  Akim Demaille  <akim@epita.fr>
4237
4238         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
4239         * src/LR0.c (set_state_table): here.
4240         * src/lalr.c (lalr): Call it.
4241
4242 2001-12-10  Akim Demaille  <akim@epita.fr>
4243
4244         * src/state.h (shifts): Remove the `number' member: shifts are
4245         attached to state, hence no longer need to be labelled with a
4246         state number.
4247
4248 2001-12-10  Akim Demaille  <akim@epita.fr>
4249
4250         Now that states have a complete set of members, the linked list of
4251         shifts is useless: just fill directly the state's shifts member.
4252
4253         * src/state.h (shifts): Remove the `next' member.
4254         * src/LR0.c (first_state, last_state): Remove.
4255         Adjust the callers.
4256         (augment_automaton): Don't look for the shifts that must be added
4257         a shift on EOF: it is those of the state we looked for!  But now,
4258         since shifts are attached, it is no longer needed to looking
4259         merely by its id: its number.
4260
4261 2001-12-10  Akim Demaille  <akim@epita.fr>
4262
4263         * src/LR0.c (augment_automaton): Better variable locality.
4264         Remove an impossible branch: if there is a state corresponding to
4265         the start symbol being shifted, then there is shift for the start
4266         symbol from the initial state.
4267
4268 2001-12-10  Akim Demaille  <akim@epita.fr>
4269
4270         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4271         only when appropriate: when insert_start_shifting_state' is not
4272         invoked.
4273         * tests/regression.at (Rule Line Numbers): Adjust.
4274
4275 2001-12-10  Akim Demaille  <akim@epita.fr>
4276
4277         * src/LR0.c (augment_automaton): Now that all states have shifts,
4278         merge the two cases addition shifts to the initial state.
4279
4280 2001-12-10  Akim Demaille  <akim@epita.fr>
4281
4282         * src/lalr.c (set_state_table): Move to...
4283         * src/LR0.c: here.
4284         * src/lalr.c (lalr): Don't call it...
4285         * src/LR0.c (generate_states): do it.
4286         * src/LR0.h (first_state): Remove, only the table is used.
4287
4288 2001-12-10  Akim Demaille  <akim@epita.fr>
4289
4290         * src/LR0.h (first_shift, first_reduction): Remove.
4291         * src/lalr.c: Don't use first_shift: find shifts through the
4292         states.
4293
4294 2001-12-10  Akim Demaille  <akim@epita.fr>
4295
4296         * src/LR0.c: Attach shifts to states as soon as they are
4297         computed.
4298         * src/lalr.c (set_state_table): Instead of assigning shifts to
4299         state, just assert that the mapping was properly done.
4300
4301 2001-12-10  Akim Demaille  <akim@epita.fr>
4302
4303         * src/LR0.c (insert_start_shift): Rename as...
4304         (insert_start_shifting_state): this.
4305         (insert_eof_shifting_state, insert_accepting_state): New.
4306         (augment_automaton): Adjust.
4307         Better locality of the variables.
4308         When looking if the start_symbol is shifted from the initial
4309         state, using `while (... symbol != start_symbol ...)' sounds
4310         better than `while (... symbol < start_symbol ...)': If fail
4311         to see how the order between symbols could be relevant!
4312
4313 2001-12-10  Akim Demaille  <akim@epita.fr>
4314
4315         * src/getargs.h: Don't declare `spec_name_prefix' and
4316         `spec_file_prefix', declared by src/files.h.
4317         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4318         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4319         * src/output.c (prepare): Adjust.
4320         * src/reader.c (symbols_output): Likewise.
4321         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4322
4323 2001-12-10  Akim Demaille  <akim@epita.fr>
4324
4325         * src/muscle_tab.c (muscle_init): NULL is a better default than
4326         `"0"'.
4327
4328 2001-12-10  Akim Demaille  <akim@epita.fr>
4329
4330         * src/reader.c (reader): Calling symbols_output once is enough.
4331
4332 2001-12-10  Akim Demaille  <akim@epita.fr>
4333
4334         Now that states have a complete set of members, the linked list of
4335         reductions is useless: just fill directly the state's reductions
4336         member.
4337
4338         * src/state.h (struct reductions): Remove member `number' and
4339         `next'.
4340         * src/LR0.c (first_reduction, last_reduction): Remove.
4341         (save_reductions): Don't link the new reductions, store them in
4342         this_state.
4343         * src/lalr.c (set_state_table): No need to attach reductions to
4344         states, it's already done.
4345         * src/output.c (output_actions): No longer free the shifts, then
4346         the reductions, then the states: free all the states and their
4347         members.
4348
4349 2001-12-10  Akim Demaille  <akim@epita.fr>
4350
4351         * src/options.c (OPTN, DRTV, BOTH): New.
4352         (option_table): Use them.
4353
4354         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4355         the job of system.h.
4356         * src/options.c: Don't include stdio.h and xalloc.h for the same
4357         reasons.
4358
4359 2001-12-10  Akim Demaille  <akim@epita.fr>
4360
4361         * src/output.c (output, prepare): Make sure the values of the
4362         muscles `action' and `prologue' are 0-terminated.
4363
4364 2001-12-10  Akim Demaille  <akim@epita.fr>
4365
4366         Clean up GCC warnings.
4367
4368         * src/reader.c (copy_action): `buf' is not used.
4369         (parse_skel_decl): Be static.
4370         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4371         * src/options.h (create_long_option_table): Have a real prototype.
4372         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4373         (hash_delete_at): Return const void *.
4374         Adjust casts to preserve the const.
4375
4376 2001-12-10  Akim Demaille  <akim@epita.fr>
4377
4378         * configure.in: Require 2.52g.
4379         M4 is not needed, but AUTOM4TE is.
4380         * m4/m4.m4: Remove.
4381         * tests/Makefile.am: Adjust.
4382
4383 2001-12-10  Akim Demaille  <akim@epita.fr>
4384
4385         One structure for states is enough, even though theoretically
4386         there are LR(0) states and LALR(1) states.
4387
4388         * src/lalr.h (state_t): Remove.
4389         (state_table): Be state_t **, not state_t *.
4390         * src/state.h (core, CORE_ALLOC): Rename as...
4391         (state_t, STATE_ALLOC): this.
4392         Add the LALR(1) members: shifts, reductions, errs.
4393         * src/LR0.c (state_table): Rename as...
4394         (state_hash): this, to avoid name clashes with the global
4395         `state_table'.
4396         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4397         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

4401         Bison dumps core on bash.y.
4402         Reported by Pascal Bart.
4403
4404         * src/warshall.c (bitmatrix_print): New.
4405         (TC): Use it.
4406         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4407         j must be the outer loop.
4408         * tests/regression.at (Broken Closure): New.
4409
4410 2001-12-05  Akim Demaille  <akim@epita.fr>
4411
4412         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4413         its argument.
4414         Reported by Peter Hámorský.
4415
4416 2001-12-05  Akim Demaille  <akim@epita.fr>
4417
4418         * src/conflicts.c (err_table): Remove.
4419         (resolve_sr_conflict): Adjust.
4420         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4421         Rename as...
4422         (state_t.reductions, state_t.shifts): this.
4423
4424 2001-12-05  Akim Demaille  <akim@epita.fr>
4425
4426         * src/reduce.c (reduce_grammar_tables): No longer disable the
4427         removal of useless rules via CPP but via `if (0)', so that the
4428         compiler still check the code is valid.
4429         For instance, it should have noticed `rline' no longer exists: use
4430         the `line' member of rule_t.
4431         * src/gram.c (dummy, rline): Remove, unused.
4432
4433 2001-12-05  Akim Demaille  <akim@epita.fr>
4434
4435         * src/output.c (pack_vector): Use assert, not berror.
4436         * src/main.c (berror): Remove, unused.
4437
4438 2001-12-05  Akim Demaille  <akim@epita.fr>
4439
4440         New experimental feature: if --verbose --trace output all the
4441         items of a state, not only its kernel.
4442
4443         * src/print.c (print_core): If `trace_flag', then invoke closure
4444         before outputting the items of the state (print_core is no longer
4445         a correct name them).
4446         (print_results): Invoke new_closure/free_closure if needed.
4447
4448 2001-12-05  Akim Demaille  <akim@epita.fr>
4449
4450         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4451         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4452         (nitemset): for consistency with the rest of the project.

4456         * src/closure.c (print_closure): Improve.
4457         (closure): Use it for printing input and output.
4458
4459 2001-12-05  Akim Demaille  <akim@epita.fr>
4460
4461         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4462         indexed by nonterminals.
4463
4464 2001-12-05  Akim Demaille  <akim@epita.fr>
4465
4466         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4467         what it was!).
4468         * src/warshall.h: Remove accidental duplication of the content.
4469
4470 2001-12-05  Akim Demaille  <akim@epita.fr>
4471
4472         * src/closure.c (set_fderives): De-obfuscate.
4473

4479
4480         * src/closure.c (set_firsts): De-obfuscate.
4481
4482 2001-12-05  Akim Demaille  <akim@epita.fr>
4483
4484         * src/output.c (action_row): De-obfuscate
4485         using the good o' techniques: arrays not pointers, variable
4486         locality, BITISSET, RESETBIT etc.
4487
4488 2001-12-05  Akim Demaille  <akim@epita.fr>
4489
4490         Pessimize the code to simplify it: from now on, all the states
4491         have a valid SHIFTS, which NSHIFTS is possibly 0.
4492
4493         * src/LR0.c (shifts_new): Be global and move to..
4494         * src/state.c, src/state.h: here.
4495         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4496         * src/print_graph: Adjust.
4497
4498 2001-12-05  Akim Demaille  <akim@epita.fr>
4499
4500         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4501         * src/conflicts.c: Use it.
4502         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4503         incorrectly ``simplified''.
4504
4505 2001-12-05  Akim Demaille  <akim@epita.fr>
4506
4507         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4508         using the good o' techniques: arrays not pointers, variable
4509         locality, BITISSET, RESETBIT etc.
4510
4511 2001-12-05  Akim Demaille  <akim@epita.fr>
4512
4513         * src/state.h (SHIFT_SYMBOL): New.
4514         * src/conflicts.c: Use it to deobfuscate.
4515
4516 2001-12-05  Akim Demaille  <akim@epita.fr>
4517
4518         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4519         (print_reductions): De-obfuscate using the good o' techniques:
4520         arrays not pointers, variable locality, BITISSET.
4521
4522 2001-12-05  Akim Demaille  <akim@epita.fr>
4523
4524         * src/conflicts.c (print_reductions): Arrays, not pointers.
4525         Use BITISSET.
4526
4527 2001-12-05  Akim Demaille  <akim@epita.fr>
4528
4529         * src/conflicts.c (print_reductions): Pessimize, but clarify.
4530
4531 2001-12-05  Akim Demaille  <akim@epita.fr>
4532
4533         * src/conflicts.c (print_reductions): Improve variable locality.
4534
4535 2001-12-05  Akim Demaille  <akim@epita.fr>
4536
4537         * src/conflicts.c (print_reductions): Pessimize, but clarify.

4542
4543 2001-12-05  Akim Demaille  <akim@epita.fr>
4544
4545         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
4546         * src/lalr.c: Use them.
4547
4548 2001-12-05  Akim Demaille  <akim@epita.fr>
4549
4550         * src/LR0.c (augment_automaton): Formatting changes.
4551         Better variable locality.
4552
4553 2001-12-05  Akim Demaille  <akim@epita.fr>
4554
4555         * src/lalr.c (matrix_print): New.
4556         (transpose): Use it.
4557         Use arrays instead of pointers.
4558
4559 2001-12-05  Akim Demaille  <akim@epita.fr>
4560
4561         * src/lalr.c (maxrhs): Move to...
4562         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4563         * src/lalr.c (build_relations): Adjust.
4564
4565 2001-12-05  Akim Demaille  <akim@epita.fr>
4566
4567         * src/lalr.c (transpose): Free the memory allocated to the
4568         argument, as it is replaced by the results by the unique caller.
4569         (build_relations): Merely invoke transpose: it handles the memory
4570         deallocation.
4571         Improve variable locality.
4572         Avoid variables used as mere abbreviations.
4573         (compute_lookaheads): Use arrays instead of pointers.
4574
4575 2001-12-05  Akim Demaille  <akim@epita.fr>
4576
4577         * src/lalr.c (initialize_F): Improve variable locality.
4578         Avoid variables used as mere abbreviations.
4579
4580 2001-12-05  Akim Demaille  <akim@epita.fr>
4581
4582         * src/derives.c (print_derives): Display the ruleno.
4583         * src/lalr.c (initialize_F, transpose): Better variable locality
4584         to improve readability.
4585         Avoid variables used as mere abbreviations.
4586
4587 2001-12-05  Akim Demaille  <akim@epita.fr>
4588
4589         * src/lalr.c (traverse): Use arrays instead of pointers.
4590
4591 2001-12-05  Akim Demaille  <akim@epita.fr>
4592
4593         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4594         the handling of squeue.
4595         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4596
4597 2001-12-05  Akim Demaille  <akim@epita.fr>
4598
4599         Because useless nonterminals are now kept alive (instead of being
4600         `destroyed'), we now sometimes examine them, and store information
4601         related to them.  Hence we need to know their number, and adjust
4602         memory allocations.
4603
4604         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4605         static.
4606         * src/LR0.c (allocate_itemsets): The memory allocated to
4607         `symbol_count' was used for two different purpose: once to count
4608         the number of occurrences of each symbol, and later reassigned to
4609         `shift_symbol', containing the symbol that can be shifted from a
4610         given state.
4611         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4612         only, and...
4613         (new_itemsets): Allocate `shift_symbol' here.
4614         (allocate_itemsets): symbol_count includes useless nonterminals.
4615         Make room for them.
4616         (free_storage): Use `free', not `XFREE', for pointers that cannot
4617         be null.
4618
4619 2001-12-05  Akim Demaille  <akim@epita.fr>
4620
4621         * src/nullable.c (set_nullable): Deobfuscate the handling of
4622         ritem.
4623         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4624
4625 2001-12-05  Akim Demaille  <akim@epita.fr>
4626
4627         * src/gram.c, src/gram.h (ritem_print): New.
4628         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4629         (This useless function was defined only to work around VMS linkers
4630         that can't handle compilation units with variables only).
4631         * src/reduce.c (dump_grammar): Use it to trace the construction of
4632         ritem.
4633
4634 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4635
4636         * src/bison.simple (union yyalloc): Change member names
4637         to be the same as the stack names.
4638         (yyparse): yyptr is now union yyalloc *, not char *.
4639         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4640         and may generate better code on some machines.
4641         (yystpcpy): Use prototype if __STDC__ is defined, not just
4642         if __cplusplus is defined.
4643
4644 2001-11-30  Akim Demaille  <akim@epita.fr>
4645
4646         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4647         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4648         Gettext doesn't compile cleanly, and dies with -Werror.
4649         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4650         Include WARNING_CFLAGS here.
4651         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4652         before being defined.
4653
4654 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4655
4656         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4657         First arg is int, not unsigned.
4658         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4659         (SIZE_MAX, UINT_MAX): New macros.
4660         (quotearg_n_options): Abort if N is negative.
4661         Avoid overflow check on hosts where size_t is 64 bits and int
4662         is 32 bits, as overflow is impossible there.
4663         Fix off-by-one typo that caused unnecessary reallocation.
4664
4665 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4666
4667         Name space cleanup in generated parser.
4668
4669         * doc/bison.texinfo (Bison Parser): Discuss system headers
4670         and their effect on the user name space.
4671
4672         * src/bison.simple:
4673         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4674         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4675         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4676
4677         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4678         on user names when possible.
4679
4680         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4681         Simplify test for whather <alloca.h> exists.
4682
4683         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4684
4685         (<stdio.h>): Include if YYDEBUG.
4686
4687         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4688         ! defined (yyoverflow) && ! defined (yymemcpy).
4689
4690         (yymemcpy, yyparse): Rename local variables as needed so that
4691         they all begin with 'yy'.
4692
4693         (yystrlen, yystpcpy): New functions.
4694
4695         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4696         All uses changed.
4697
4698         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4699         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4700         and YYSTACK_FREE instead of malloc and free.
4701
4702 2001-11-30  Akim Demaille  <akim@epita.fr>
4703
4704         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4705         before their first uses.
4706         (YYBISON, YYPURE): Move to the top of the output.
4707
4708 2001-11-30  Akim Demaille  <akim@epita.fr>
4709
4710         * tests/reduce.at (Useless Nonterminals): Fix.
4711
4712 2001-11-30  Akim Demaille  <akim@epita.fr>
4713
4714         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4715         if body instead of `;' to pacify GCC's warnings.
4716
4717 2001-11-30  Akim Demaille  <akim@epita.fr>
4718
4719         Instead of mapping the LHS of unused rules to -1, keep the LHS
4720         valid, but flag the rules as invalid.
4721
4722         * src/gram.h (rule_t): `useful' is a new member.
4723         * src/print.c (print_grammar): Adjust.
4724         * src/derives.c (set_derives): Likewise.
4725         * src/reader.c (packgram, reduce_output): Likewise.
4726         * src/reduce.c (reduce_grammar_tables): Likewise.
4727         * tests/reduce.at (Underivable Rules, Useless Rules): New.
4728
4729 2001-11-30  Akim Demaille  <akim@epita.fr>
4730
4731         * src/reduce.c (reduce_output): Formatting changes.
4732         * src/print.c (print_results, print_grammar): Likewise.
4733         * tests/regression.at (Rule Line Numbers)
4734         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4735
4736 2001-11-30  Akim Demaille  <akim@epita.fr>
4737
4738         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4739         useless nonterminals, move them at the end of the symbol arrays.
4740         (reduce_output): Adjust.
4741         * tests/reduce.at (Useless Nonterminals): Adjust.
4742
4743 2001-11-30  Akim Demaille  <akim@epita.fr>
4744
4745         * src/reduce.c: Various comment/formatting changes.
4746         (nonterminals_reduce): New, extracted from...
4747         (reduce_grammar_tables): here.
4748         (reduce_grammar): Call nonterminals_reduce.
4749
4750 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4751
4752         * src/bison.simple (YYSTACK_REALLOC): Remove.
4753         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4754         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4755         New macros.
4756         (union yyalloc): New type.
4757         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4758         an arbitrary restriction on hosts where size_t is wider than int.
4759
4760         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4761         a parser stack overflow.  Allocate just one block of memory for all
4762         three stacks, instead of allocating three blocks; this typically is
4763         faster and reduces fragmentation.
4764
4765         Do not limit the number of items in the stack to a value that fits
4766         in 'int', as this is an arbitrary limit on hosts with 64-bit
4767         size_t and 32-bit int.
4768
4769 2001-11-29  Marc Autret  <autret_m@epita.fr>
4770
4771         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4772         of defining YYERROR_VERBOSE.
4773         [AT_DATA]: $4 is now out of C declarations in the prologue.
4774
4775 2001-11-28  Marc Autret  <autret_m@epita.fr>
4776
4777         * src/reader.c (parse_dquoted_param): New.
4778         (parse_skel_decl): Use it.
4779         * src/lex.h: Add its prototype.
4780         * src/lex.c (literalchar): Become not static.
4781
4782 2001-11-28  Marc Autret  <autret_m@epita.fr>
4783
4784         * src/output.h: And put its extern declaration here.
4785         * src/output.c (error_verbose): Define here.
4786         (prepare): Echo name modification.
4787         * src/getargs.h: Clean its extern declaration.
4788         * src/getargs.c (error_verbose_flag): Remove.
4789         (getargs): Remove case 'e'.
4790         * src/options.c (option_table): 'error-verbose' is now seen as simple
4791         percent option.
4792         Include output.h.
4793
4794         * src/reader.c (read_declarations): Remove case tok_include.
4795         (parse_include_decl): Remove.
4796         * src/lex.h (token_t): Remove tok_include.
4797         * src/options.c (option_table): 'include' is now a simple command line
4798         option.
4799
4800 2001-11-28  Marc Autret  <autret_m@epita.fr>
4801
4802         * src/bison.simple: Adjust muscle names.
4803         * src/muscle_tab.c (muscle_init): Also rename the muscles.
4804         * src/output.c (prepare): s/_/-/ for the muscles names.
4805         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
4806
4807 2001-11-28  Marc Autret  <autret_m@epita.fr>
4808
4809         * src/bison.simple: Fix debug.

5195         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
5196         now the tests are run in private dirs, therefore AC_CLEANUP and
5197         family can be simplified to 0-ary.
5198         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
5199         use abs. path to find config.h.
5200         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

5224         arg_offset.

5323         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
5324         with yyltype/YYLTYPE.  This allows inclusion of the generated

6594         the obstacks.
6595
6596         * src/lex.c (token_obstack): New.
6597         (init_lex): Initialize it.  No longer call...

6600
6601 2001-01-19  Akim Demaille  <akim@epita.fr>
6602
6603         * src/lex.h: Rename all the tokens:
6604         s/\bENDFILE\b/tok_eof/g;
6605         s/\bIDENTIFIER\b/tok_identifier/g;
6606         etc.
6607         Let them be enums, not #define, to ease debugging.

6617         Since we now use obstacks, more % directives can be enabled.
6618
6619         * src/lex.c (percent_table): Also accept `%yacc',
6620         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
6621         `%debug'.
6622         Handle the actions for `%semantic_parser' and `%pure_parser' here,
6623         instead of returning a token.

6625         * src/reader.c (read_declarations): Adjust.
6626         * src/files.c (open_files): Don't call `compute_base_names', don't
6627         compute `attrsfile' since they depend upon data which might be
6628         *in* the input file now.
6629         (output_files): Do it here.
6630         * src/output.c (output_headers): Document the fact that this patch
6631         introduces a guaranteed SEGV for semantic parsers.
6632         * doc/bison.texinfo: Document them.

6656         FILE * parameters.
6657
6658 2000-12-20  Akim Demaille  <akim@epita.fr>
6659
6660         * src/files.c (open_files): Actually the `.output' file is based
6661         on the short_base_name, not base_name.
6662         * tests/suite.at (Checking output file names): Adjust.
6663
6664 2000-12-20  Akim Demaille  <akim@epita.fr>

6690         (stringappend): Be just like strcat but allocate.
6691         (base_names): Eve out from open_files.

6695         * tests/suite.at (Checking output file names): New test.

6712
6713 2000-12-19  Akim Demaille  <akim@epita.fr>
6714
6715         Let the handling of the skeleton files be local to the procedures
6716         that use it.
6717
6718         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
6719         longer static.

6733 2000-12-19  Akim Demaille  <akim@epita.fr>
6734
6735         * src/files.c (open_files): Yipee!  We no longer need all the code
6736         looking for `/tmp' since we have no tmp file.
6737
6738 2000-12-19  Akim Demaille  <akim@epita.fr>

6767         * lib/obstack.h: Formatting changes.
6768         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6769         prevents type checking.
6770         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6771         cast the value to (void *): assigning a `foo *' to a `void *'
6772         variable is valid.
6773         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
6774         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6811

6856         when there are no errors.

6960
6961         When a literal string is used to define two different tokens,
6962         `bison -v' segfaults.
6963         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6964
6965         * tests/regression.m4: New file.
6966         Include the core of the sample provided by Piotr Gackiewicz.
6967         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
6968         properly.

6971
6972         * src/reader.c (parse_expect_decl): Keep `count' within the size
6973         of `buffer'.

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

7122
7123 2000-10-02  Akim Demaille  <akim@epita.fr>
7124
7125         * src/state.h (nstates, final_state, first_state, first_shift)

7203 2000-10-02  Akim Demaille  <akim@epita.fr>
7204
7205         * src/output.c (token_actions): Introduce a temporary array,

7207         output_short_table.
7208
7209 2000-10-02  Akim Demaille  <akim@epita.fr>
7210
7211         `user_toknums' is output as a `short[]' in `output.c', while it is
7212         defined as a `int[]' in `reader.c'.  For consistency with the
7213         other output tables, `user_toknums' is now defined as a table of
7214         shorts.
7215
7216         * src/reader.c (user_toknums): Be a short table instead of an int
7217         table.

7229         order to get rid of the `static' prototypes.
7230         No longer use `register'.
7231         * src/output.h: New file.
7232         Propagate its inclusion in files explicitly prototyping functions
7233         from output.c.

7255         inclusion.
7256         Don't define PARAMS.
7257         * src/system.h: Define PARAMS.
7258         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7259         purpose of config.h.  system.h must not try to fix wrong
7260         definitions in config.h.

7285         Let all `extern' declarations about getargs.c be replaced with

7300
7301         * configure.in: Append WARNING_CFLAGS to CFLAGS.

7423
7424 2000-03-17  Akim Demaille  <akim@epita.fr>
7425
7426         On syntax errors, report the token on which we choked.
7427

7448         copy_comment.  Removed now unused `match', `ended',
7449         `cplus_comment'.
7450         (copy_comment, copy_string): Moved, to be visible from
7451         copy_definition.

7454

7477
7478         Change the handling of @s so that they behave exactly like $s.
7479         There is now a pseudo variable @$ (readble and writable), location
7480         of the lhs of the rule (by default ranging from the location of
7481         the first symbol of the rhs, to the location of the last symbol,
7482         or, if the rhs is empty, YYLLOC).
7483
7484         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7485         yyval.
7486         (yyparse): When providing a default semantic action, provide a
7487         default location action.
7488         (after the $): No longer change `*YYLSP', just stack YYLOC the
7489         same way you stack YYVAL.
7490         * src/reader.c (read_declarations): Use warns.
7491         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7492         (copy_action, case '@'): Likewise.
7493         Use a standard error message, to save useless work from
7494         translators.
7495
7496 2000-03-17  Akim Demaille  <akim@epita.fr>
7497

7515
7516         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7517         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7518         One `#if YYDEBUG' remains, since it uses variables which are
7519         defined only if `YYDEBUG != 0'.
7520
7521 2000-03-16  Akim Demaille  <akim@epita.fr>

7547         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

7553         the proper line number and file name.
7554         (DEFS): Propagate the location of bison library files and of the
7555         locale files.
7556         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7557         builddir.
7558         * acinclude.m4: Remove, replaced by the directory m4.
7559         * m4/Makefile.am (EXTRA_DIST): New variable.

8247         major changes to files.c.
8248         (lex) Retain in the incoming stream a character following
8249         an incorrect '/'.
