  15
  16         * data/yacc.c (yyreport_parse_error): Remove, putting its body into...

  31
  32 2002-10-10  Paul Eggert  <eggert@twinsun.com>
  33
  34         Portability fixes for bitsets; this also avoids several GCC
  35         warnings.
  36
  37         * lib/abitset.c: Include <stddef.h>, for offsetof.
  38         * lib/lbitset.c: Likewise.
  39
  40         * lib/abitset.c (abitset_bytes): Return a size that is aligned
  41         properly for vectors of objects.  Do not assume that adding a
  42         header size to a multiple of a word size yields a value that is
  43         properly aligned for the whole union.
  44         * lib/bitsetv.c (bitsetv_alloc): Likewise.
  45
  46         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
  47         unique names for structures.
  48         * lib/ebitset.c (ebitset_bytes): Likewise.
  49         * lib/lbitset.c (lbitset_bytes): Likewise.
  50
  51         * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
  52         abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
  53         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
  54         abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
  55         abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
  56         abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
  57         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
  58         to improve the type-checking that GCC can do.
  59         * lib/bitset.c (bitset_op4_cmp): Likewise.
  60         * lib/bitset_stats.c (bitset_stats_count,
  61         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
  62         bitset_stats_copy, bitset_stats_disjoint_p,
  63         bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
  64         bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
  65         bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
  66         bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
  67         bitset_stats_and_or_cmp, bitset_stats_andn_or,
  68         bitset_stats_andn_or_cmp, bitset_stats_or_and,
  69         bitset_stats_or_and_cmp): Likewise.
  70         * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
  71         lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
  72         lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
  73         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
  74
  75         * lib/abitset.h: Include bitset.h, not bbitset.h.
  76         * lib/ebitset.h: Likewise.
  77         * lib/lbitset.h: Likewise.
  78
  79         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
  80         All instances of parameters of type enum bitset_opts are now of
  81         type enum_bitset_opts, to conform to the C Standard, and similarly
  82         for enum_bitset_type.
  83         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
  84         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
  85
  86         Do not use "struct bitset_struct" to mean different things in
  87         different modules.  Not only is this confusing, it violates
  88         the C Standard, which requires that structure types in different
  89         modules must be compatible if one is to be passed to the other.
  90         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
  91         All instances of "struct bitset_struct *" replaced with "bitset".
  92         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
  93         (union bitset_union, struct abitset_struct, struct ebitset_struct,
  94         struct lbitset_struct, struct bitset_stats_struct): New types.
  95         All uses of struct bitset_struct changed to union bitset_union,
  96         etc.
  97         * lib/abitset.c (struct abitset_struct, abitset,
  98         struct bitset_struct): Remove.
  99         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
 100         struct bitset_struct): Remove.
 101         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
 102         bitset_struct): Remove.
 103         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
 104         Likewise.
 105
 106         Do not call a function of type T using a call that assumes the
 107         function is of a different type U.  Standard C requires that a
 108         function must be called with a type that is compatible with its
 109         definition.
 110         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 111         New decls.
 112         * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 113         New functions.
 114         * lib/ebitset.c (PFV): Remove.
 115         * lib/lbitset.c (PFV): Likewise.
 116         * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
 117         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
 118         decls.
 119         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
 120         (ebitset_vtable): Use them.
 121         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
 122         lbitset_xor): New functions.
 123         (lbitset_vtable): Use them.
 124
 125         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
 126         Declare.
 127
 128         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
 129         GCC warning.
 130         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
 131         Use offsetof, for simplicity.
 132
 133 2002-10-06  Paul Eggert  <eggert@twinsun.com>
 134
 135         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
 136         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
 137         <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
 138         which was inadvertently undone by the 2002-09-30 patch.
 139         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
 140         the same width as int.
 141
 142 2002-10-04  Paul Eggert  <eggert@twinsun.com>
 143
 144         Version 1.50.
 145
 146         * configure.ac (AC_INIT), NEWS: Increment version number.
 147
 148         * doc/bison.texinfo: Minor spelling, grammar, and white space
 149         fixes.
 150         (Symbols): Mention that any negative value returned from yylex
 151         signifies end-of-input.  Warn about negative chars.  Mention
 152         the portable Standard C character set.
 153
 154         The GNU coding standard says CFLAGS and YFLAGS are reserved
 155         for the installer to set.
 156         * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
 157         * src/Makefile.am (AM_CFLAGS): Likewise.
 158         (AM_YFLAGS): Renamed from YFLAGS.
 159
 160         Fix some MAX and MIN problems.
 161         * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
 162         * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
 163         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
 164         * src/reader.c (reader): Use it.
 165
 166         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
 167         POSIX 1003.1-2001 has removed fgrep.
 168
 169 2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
 170
 171         * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
 172         interpreted as signed.
 173         * lib/ebitset.c (ebitset_list): Fix bug.
 174
 175 2002-10-01  Paul Eggert  <eggert@twinsun.com>
 176
 177         More fixes for 64-bit hosts and large bitsets.
 178
 179         * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
 180         abitset_size, abitset_list, abitset_list_reverse, abitset_list):
 181         Use bitset_bindex, not int or unsigned int or size_t, to count bits.

 183         struct bitset_vtable.list, struct bitset_vtable.list_reverse,

 185         bitset_count_): Likewise.
 186         * lib/bitset.h (bitset_iterator.num, bitset_iterator.i,
 187         bitset_first, bitset_last): Likewise.
 188         * lib/bitset_stats.c (bitset_stats_size, bitset_stats_list,
 189         bitset_stats_list_reverse, bitset_stats_size,
 190         bitset_stats_count, bitset_stats_list, bitset_stat_list_reverse):
 191         Likewise.
 192         * lib/bitsetv-print.c (bitsetv_matrix_dump): Likewise.
 193         * lib/bitsetv.c (bitsetv_alloc, bitsetv_create, bitsetv_free,

 201
 202         * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):

 215
 216         * lib/abitset.c (abitset_empty_p, abitset_not, abitset_equal_p,
 217         abitset_subset_p, abitset_disjoint_p, abitset_and,
 218         abitset_and_cmp, abitset_andn, abitset_andn_cmp, abitset_or,

 238         * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
 239         BITSET_SIZE_MAX): New macros.
 240         (BITSET_INDEX_MAX): Remove.  It wasn't right, since it assumed that
 241         sizeof (bitset_word) == sizeof (bitset_windex).  All uses changed
 242         to BITSET_WINDEX_MAX.
 243
 244         * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
 245         bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

 251
 252         * lib/lbitset.c (lbitset_elt_find): Simplify windex calculation
 253         and avoid cast to unsigned.

 345
 346         * doc/bison.texinfo (Conditions): Make explicit that the GPL

 356         * data/lalr1.cc (struct yyltype): Don't define it, since we use
 357         LocationType.
 358         (b4_ltype): Default to yy::Location from location.hh.
 359
 360 2002-09-04  Jim Meyering  <jim@meyering.net>
 361
 362         * data/yacc.c: Guard the declaration of yytoknum also with
 363         `#ifdef YYPRINT', so it is declared only when used.
 364
 365 2002-09-04  Akim Demaille  <akim@epita.fr>
 366
 367         * configure.in: Rename as...

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

 395         (yyreportParseError): Use size_t for yysize.
 396         (yy_yypstack): No longer nested inside yypstates, as nested
 397         functions are not portable.  Do not assume size_t is the
 398         same width as int.
 399         (yypstates): Do not assume that ptrdiff_t is the same width
 400         as int, and similarly for yyposn and YYINDEX.
 401
 402         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 403
 404         * lib/Makefile.am (INCLUDES): Do not include from the intl
 405         directory, which has been removed.
 406         * src/Makefile.am (INCLUDES): Likewise.

 427         portability to one's complement hosts!).
 428         * lib/ebitset.c (ebitset_op1): Likewise.
 429         * lib/lbitset.c (lbitset_op1): Likewise.
 430

 436         lib/gettext.h: Sync with diffutils.
 437

 439         lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
 440
 441         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 442         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 443         check for void *.
 444
 445         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 446         size_t; the old version tried to do this but casted improperly.
 447         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 448         (bitset_test): Now returns int, not unsigned long.

 452         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 453         name locals "index", as it generates unnecessary warnings on some
 454         hosts that have an "index" function.
 455
 456         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 457         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
 458         they need translation.

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

 474         * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
 475
 476         * po/LINGUAS: Add pt_BR.
 477         * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
 478         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 479         lib/timevar.c.
 480         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 481         manual recommends.
 482         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 483
 484         * src/complain.c (strerror_r): Remove decl; not needed.
 485         (strerror): Use same pattern as ../lib/error.c.

 490
 491         * src/main.c (main): Cast result of bindtextdomain and textdomain
 492         to void, to avoid a GCC warning when --disable-nls is in effect.
 493
 494         * src/scan-gram.l: Use strings rather than escapes when possible,
 495         to minimize the number of warnings from xgettext.
 496         (handle_action_dollar, handle_action_at): Don't use isdigit,
 497         as it mishandles negative chars and it may not work as expected
 498         outside the C locale.
 499
 500         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 501         this is a GCC extension and is not portable to other compilers.
 502
 503         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 504         Do not include <ctype.h>; no longer needed.
 505         Do not include <malloc.h>; no longer needed (and generates
 506         warnings on OpenBSD 3.0).
 507
 508         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
 509         it's not portable.
 510
 511         * tests/regression.at: Do not use 'cc -c input.c -o input';
 512         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
 513
 514         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
 515         exit status as failure, not just exit status 1.  Sun C exits
 516         with status 2 sometimes.
 517
 518         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
 519         Use it for the two large tests.

 522
 523         * src/conflicts.c (conflicts_output): Don't output rules never
 524         reduced here, since anyway that computation doesn't work.
 525         * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
 526         (rule_useless_p, rule_never_reduced_p): New.

 532         reduced to...
 533         (token_actions): here.
 534         * src/main.c (main): Make the parser before making the report, so
 535         that rules never reduced are computed.
 536         Call grammar_rules_never_reduced_report.
 537         * src/print.c (print_results): Report rules never reduced.
 538         * tests/conflicts.at, tests/reduce.at: Adjust.
 539
 540 2002-08-01  Akim Demaille  <akim@epita.fr>
 541
 542         Instead of attaching lookaheads and duplicating the rules being
 543         reduced by a state, attach the lookaheads to the reductions.
 544
 545         * src/state.h (state_t): Remove the `lookaheads',
 546         `lookaheads_rule' member.
 547         (reductions_t): Add a `lookaheads' member.

 550         to 0.
 551         (state_rule_lookaheads_print): Adjust.

 559         (initialize_LA): this.
 560         (lalr_free): Adjust.
 561         * src/main.c (main): Don't free nullable and derives too early: it
 562         is used by --verbose.
 563         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
 564
 565 2002-08-01  Akim Demaille  <akim@epita.fr>
 566
 567         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of

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

 590         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
 591         (tables_generate): do it, since that's also it which allocates
 592         them.
 593         Don't free LA and LArule, main does.
 594
 595 2002-07-31  Akim Demaille  <akim@epita.fr>
 596
 597         Separate parser tables computation and output.

 656
 657 2002-07-30  Akim Demaille  <akim@epita.fr>
 658
 659         In verbose parse error message, don't report `error' as an

 661         * tests/actions.at (Printers and Destructors): Adjust.
 662         * tests/calc.at (Calculator $1): Adjust.
 663         * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose

 677 2002-07-30  Akim Demaille  <akim@epita.fr>

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

 699         * configure.in: Look for malloc.h and sys/times.h.
 700         * src/main.c (stage): Adjust.

 720         Set undeftoken's tag to "$undefined" instead of "$undefined.".
 721         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
 722         Adjust.
 723
 724 2002-07-29  Akim Demaille  <akim@epita.fr>
 725
 726         * src/reduce.c (reduce_grammar): When the language is empty,
 727         complain about the start symbol, not the axiom.
 728         Use its location.
 729         * tests/reduce.at (Empty Language): New.

 737         token_translations instead of `0'.
 738         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
 739         visible here.
 740         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
 741         for the time being: %locations ought to provide it to yyerror.
 742
 743 2002-07-25  Akim Demaille  <akim@epita.fr>
 744
 745         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1814         grammar.
1815         Use more modest sizes, as for the time being the parser does not
1816         release memory, and therefore the process swallows a huge amount
1817         of memory.
1818
1819         * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the

1830         eccentricities.

1905
1906         Remove `%thong' support as it is undocumented, unused, duplicates
1907         `%token's job, and creates useless e-mail traffic with people who

2376         * src/reduce.c (dump_grammar): Move to...
2377         * src/gram.h, src/gram.c (grammar_dump): here.
2378         Be sure to separate long item numbers.

2380
2381 2002-04-22  Akim Demaille  <akim@epita.fr>
2382
2383         * src/output.c (table_size, table_grow): New.
2384         (MAXTABLE): Remove, replace uses with table_size.
2385         (pack_vector): Instead of dying when the table is too big, grow it.
2386
2387 2002-04-22  Akim Demaille  <akim@epita.fr>
2388
2389         * data/bison.simple (yyr1): Its type is that of a token number.

2394
2395         * src/reader.c (token_translations_init): 256 is now the default
2396         value for the error token, i.e., it will be assigned another
2397         number if the user assigned 256 to one of her tokens.
2398         (reader): Don't force 256 to error.
2399         * doc/bison.texinfo (Symbols): Adjust.

2401         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
2402         etc. instead of 10, 20, 30 (which was used to `jump' over error
2403         (256) and undefined (2)).
2404
2405 2002-04-22  Akim Demaille  <akim@epita.fr>

2411         * src/output.c (GENERATE_OUTPUT_TABLE): New.
2412         Use it to create output_item_number_table and

2426         as Lex/Flex'.
2427         (Debugging): More details about enabling the debugging features.
2428         (Table of Symbols): Describe $$, $n, @$, and @n.
2429         Suggested by Tim Josling.

2438         Suggested by Paul Eggert.
2439
2440 2002-04-09  Akim Demaille  <akim@epita.fr>
2441
2442         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2443         full stderr, and strip it according to the bison options, instead
2444         of composing the error message from different bits.
2445         This makes it easier to check for several error messages.
2446         Adjust all the invocations.
2447         Add an invocation exercising the error token.
2448         Add an invocation demonstrating a stupid error message.
2449         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
2450         Adjust the tests.
2451         Error message are for stderr, not stdout.

2453 2002-04-09  Akim Demaille  <akim@epita.fr>
2454
2455         * src/gram.h, src/gram.c (error_token_number): Remove, use
2456         errtoken->number.
2457         * src/reader.c (reader): Don't specify the user token number (2)
2458         for $undefined, as it uselessly prevents using it.
2459         * src/gram.h (token_number_t): Move to...
2460         * src/symtab.h: here.
2461         (state_t.number): Is a token_number_t.
2462         * src/print.c, src/reader.c: Use undeftoken->number instead of
2463         hard coded 2.
2464         (Even though this 2 is not the same as above: the number of the
2465         undeftoken remains being 2, it is its user token number which
2466         might not be 2).
2467         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2468         `user_token_number_max'.
2469         Output `undef_token_number'.
2470         * data/bison.simple, data/bison.c++: Use them.
2471         Be sure to map invalid yylex return values to
2472         `undef_token_number'.  This saves us from gratuitous SEGV.
2473
2474         * tests/conflicts.at (Solved SR Conflicts)
2475         (Unresolved SR Conflicts): Adjust.

2481         Adding #line.
2482         Remove the duplicate `typedefs'.
2483         (RhsNumberType): Fix the declaration and various other typos.
2484         Use __ofile__.
2485         * data/bison.simple: Use __ofile__.
2486         * src/scan-skel.l: Handle __ofile__.

2489
2490         * src/gram.h (item_number_t): New, the type of item numbers in
2491         RITEM.  Note that it must be able to code symbol numbers as
2492         positive number, and the negation of rule numbers as negative
2493         numbers.
2494         Adjust all dependencies (pretty many).
2495         * src/reduce.c (rule): Remove this `short *' pointer: use
2496         item_number_t.
2497         * src/system.h (MINSHORT, MAXSHORT): Remove.
2498         Include `limits.h'.
2499         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2500         (shortcpy): Remove.
2501         (MAXTABLE): Move to...
2502         * src/output.c (MAXTABLE): here.
2503         (prepare_rules): Use output_int_table to output rhs.
2504         * data/bison.simple, data/bison.c++: Adjust.
2505         * tests/torture.at (Big triangle): Move the limit from 254 to
2506         500.
2507         * tests/regression.at (Web2c Actions): Ajust.
2508
2509         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2510         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2511         passes, but produces negative #line number, once fixed, GCC is
2512         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2513         C), it passes.
2514         * src/state.h (state_h): Code input lines on ints, not shorts.
2515
2516 2002-04-08  Akim Demaille  <akim@epita.fr>
2517

2642 2002-04-07  Akim Demaille  <akim@epita.fr>
2643
2644         Be sure never to walk through RITEMS, but use only data related to
2645         the rules themselves. RITEMS should be banished.
2646
2647         * src/output.c (output_token_translations): Rename as...
2648         (prepare_tokens): this.
2649         In addition to `translate', prepare the muscles `tname' and

2662
2663         * src/LR0.c (new_state): Display `nstates' as the name of the
2664         newly created state.
2665         Adjust to initialize first_state and last_state if needed.
2666         Be sure to distinguish the initial from the final state.
2667         (new_states): Create the itemset of the initial state, and use
2668         new_state.
2669         * src/closure.c (closure): Now that the initial state has its
2670         items properly set, there is no need for a special case when
2671         creating `ruleset'.
2672
2673         As a result, now the rule 0, reducing to $axiom, is visible in the

3015         causing more problems than it was curing, since it didn't work
3016         properly on some nonstandard C++ compilers.  This can wait

3052         * data/bison.c++: Correct error recovery.  Make the user able to
3053         initialize the starting location.
3054
3055 2002-02-07  Akim Demaille  <akim@epita.fr>
3056
3057         * tests/input.at: New.
3058
3059 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3060
3061         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
3062         more consistent when naming methods and variables.  Put preprocessor
3063         directives around tables only needed for debugging.
3064
3065 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3066
3067         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
3068         C++ parsers.
3069         (yy::b4_name::parse): Use print_.
3070
3071 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3072
3073         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
3074
3075 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
3076
3077         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
3078         C++ parsers.
3079         (yy::b4_name::parse): Build verbose error messages, and use error_.
3080
3081 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3082
3083         * data/bison.c++: Fix m4 quoting in comments.
3084
3085 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
3086
3087         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
3088         not expanded by m4.
3089
3090 2002-02-05  Akim Demaille  <akim@epita.fr>
3091
3092         * data/bison.c++: Adjust to the M4 back end.
3093         More is certainly needed.
3094
3095 2002-02-05  Akim Demaille  <akim@epita.fr>
3096
3097         Give a try to M4 as a back end.
3098
3099         * lib/readpipe.c: New, from wdiff.
3100         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
3101         BISON_HAIRY.
3102         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
3103         specific values.  Now it is m4 that performs the lookup.
3104         * src/parse-skel.y: Remove.
3105         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
3106         * src/output.c (actions_output, guards_output)
3107         (token_definitions_output): No longer keeps track of the output
3108         line number, hence remove the second argument.
3109         (guards_output): Check against the guard member of a rule, not the
3110         action member.
3111         Adjust callers.
3112         (output_skeleton): Don't look for the skeleton location, let m4 do
3113         that.
3114         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
3115         file will be used.
3116         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3117         (prepare): Given that for the time being changesyntax is not
3118         usable in M4, rename the muscles using `-' to `_'.
3119         Define `defines_flag', `output_parser_name' and `output_header_name'.
3120         * src/output.h (actions_output, guards_output)
3121         (token_definitions_output): Adjust prototypes.
3122         * src/scan-skel.l: Instead of scanning the skeletons, it now
3123         processes the output of m4: `__oline__' and `#output'.
3124         * data/bison.simple: Adjust to be used by M4(sugar).
3125         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3126         to date.
3127         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3128         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
3129         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
3130         shamelessly stolen from CVS Autoconf.
3131
3132 2002-02-05  Akim Demaille  <akim@epita.fr>
3133
3134         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
3135         * configure.in: Check for the declarations of free and malloc.
3136         * src/muscle_tab.c: Adjust.
3137
3138 2002-02-05  Akim Demaille  <akim@epita.fr>
3139
3140         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
3141         which have no values.
3142
3143 2002-02-05  Akim Demaille  <akim@epita.fr>
3144
3145         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
3146         * data/: here.
3147
3148 2002-01-29  Paul Eggert  <eggert@twinsun.com>
3149
3150         * src/bison.simple (YYSIZE_T): Do not define merely because
3151         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3152         On some platforms, <alloca.h> does not declare YYSTD (size_t).
3153
3154 2002-01-27  Akim Demaille  <akim@epita.fr>
3155
3156         Fix `%nonassoc and eof'.
3157
3158         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
3159         which were not properly copied!  Replace
3160         memcpy (res->errs, src->errs, src->nerrs);
3161         with
3162         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3163         !!!
3164         * tests/regression.at (%nonassoc and eof): Adjust to newest
3165         Autotest: `.' is not in the PATH.
3166
3167 2002-01-27  Akim Demaille  <akim@epita.fr>
3168
3169         * tests/sets.at (AT_EXTRACT_SETS): New.
3170         (Nullable): Use it.
3171         (Firsts): New.
3172
3173 2002-01-26  Akim Demaille  <akim@epita.fr>
3174
3175         * tests/actions.at, tests/calc.at, tests/headers.at,
3176         * tests/torture.at: Adjust to the newest Autotest which no longer
3177         forces `.' in the PATH.
3178
3179 2002-01-25  Akim Demaille  <akim@epita.fr>
3180
3181         * tests/regression.at (%nonassoc and eof): New.
3182         Suggested by Robert Anisko.
3183
3184 2002-01-24  Akim Demaille  <akim@epita.fr>
3185
3186         Bison dumps core when trying to complain about broken input files.
3187         Reported by Cris van Pelt.
3188
3189         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
3190         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
3191         into...
3192         (Invalid inputs): Strengthen: exercise parse_percent_token.
3193
3194 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
3195
3196         * src/Makefile.am: Add bison.c++.
3197         * src/bison.c++: New skeleton.
3198
3199 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
3200
3201         * po/it.po: New.
3202
3203 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
3204
3205         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
3206
3207 2002-01-20  Marc Autret  <marc@gnu.org>
3208
3209         * src/files.c (compute_output_file_names): Fix
3210
3211 2002-01-20  Marc Autret  <marc@gnu.org>
3212
3213         * tests/output.at: New test.
3214         * src/files.c (compute_base_names): Don't map extensions when
3215         the YACC flag is set, use defaults.
3216         Reported by Evgeny Stambulchik.
3217
3218 2002-01-20  Marc Autret  <marc@gnu.org>
3219
3220         * src/system.h: Need to define __attribute__ away for non-GCC
3221         compilers as well (i.e. the vendor C compiler).
3222         Suggested by Albert Chin-A-Young.
3223
3224 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
3225
3226         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3227         canonical definition.
3228         * src/system.h: Use the canonical definition for PARAMS (avoids
3229         a conflict with the macro from lib/hash.h).
3230
3231 2002-01-11  Akim Demaille  <akim@epita.fr>
3232
3233         * configure.in: Use AC_FUNC_STRNLEN.
3234         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3235
3236 2002-01-09  Akim Demaille  <akim@epita.fr>
3237
3238         * src/files.c, src/files.h (output_infix): New.
3239         (tab_extension): Remove.
3240         (compute_base_names): Compute the former, drop the latter.
3241         * src/output.c (prepare): Insert the muscles `output-infix', and
3242         `output-suffix'.
3243         * src/parse-skel.y (string, string.1): New.
3244         (section.header): Use it.
3245         (section.yacc): Remove.
3246         (prefix): Remove too.
3247         * src/scan-skel.l: Adjust.
3248         * src/bison.simple, src/bison.hairy: Adjust.
3249
3250 2002-01-09  Akim Demaille  <akim@epita.fr>
3251
3252         * configure.in (WERROR_CFLAGS): Compute it.
3253         * src/Makefile.am (CFLAGS): Pass it.
3254         * tests/atlocal.in (CFLAGS): Idem.
3255         * src/files.c: Fix a few warnings.
3256         (get_extension_index): Remove, unused.
3257
3258 2002-01-08  Akim Demaille  <akim@epita.fr>
3259
3260         * src/getargs.c (AS_FILE_NAME): New.
3261         (getargs): Use it to convert DOSish file names.
3262         * src/files.c (base_name): Rename as full_base_name to avoid
3263         clashes with `base_name ()'.
3264         (filename_split): New.
3265         (compute_base_names): N-th rewrite, using filename_split.
3266
3267 2002-01-08  Akim Demaille  <akim@epita.fr>
3268
3269         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3270         New, stolen from the Fileutils 4.1.
3271         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3272         * configure.in: Check for the presence of memrchr, and of its
3273         prototype.
3274
3275 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3276
3277         * lib/hash.h (__P): Added definition for this macro.
3278         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3279         BUILT_SOURCES, to ensure they are generated first.
3280         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3281         %error-verbose to allow bootstrapping with bison 1.30x.
3282
3283 2002-01-06  Akim Demaille  <akim@epita.fr>
3284
3285         * src/reader.c (parse_braces): Don't fetch the next char, the
3286         convention is to fetch on entry.
3287         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3288         'switch' without a following semicolon.
3289         * tests/regression.at (braces parsing): New.
3290
3291 2002-01-06  Akim Demaille  <akim@epita.fr>
3292
3293         Bison is dead wrong in its RR conflict reports.
3294
3295         * tests/torture.at (GNU Cim Grammar): New.
3296         * src/conflicts.c (count_rr_conflicts): Fix.
3297
3298 2002-01-06  Akim Demaille  <akim@epita.fr>
3299
3300         Creating package.m4 from configure.ac causes too many problems.
3301
3302         * tests/Makefile.am (package.m4): Create it by hand,
3303         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3304
3305 2002-01-06  Akim Demaille  <akim@epita.fr>
3306
3307         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3308         skeleton.h.
3309
3310 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3311
3312         * doc/bison.texinfo (Debugging):
3313         Remove YYSTDERR; it's no longer defined or used.
3314         Also, s/cstdio.h/cstdio/.
3315
3316 2002-01-03  Akim Demaille  <akim@epita.fr>
3317
3318         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3319
3320 2002-01-03  Akim Demaille  <akim@epita.fr>
3321
3322         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3323         tracing code to --trace, wait for a better --trace option, with
3324         args.
3325
3326 2002-01-03  Akim Demaille  <akim@epita.fr>
3327
3328         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3329         The ISO C++ standard is extremely clear about it: stderr is
3330         considered a macro, not a regular symbol (see table 94 `Header
3331         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3332         Therefore std:: does not apply to it.  It still does with fprintf.
3333         Also, s/cstdio.h/cstdio/.
3334
3335 2002-01-03  Akim Demaille  <akim@epita.fr>
3336
3337         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3338         for non system headers.
3339
3340 2002-01-02  Akim Demaille  <akim@epita.fr>
3341
3342         Equip the skeleton chain with location tracking, runtime trace,
3343         pure parser and scanner.
3344
3345         * src/parse-skel.y: Request a pure parser, locations, and prefix
3346         renaming.
3347         (%union): Having several members with the same type does not help
3348         type mismatches, simplify.
3349         (YYPRINT, yyprint): New.
3350         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3351         (skel_error): this.
3352         Handle locations.
3353         * src/scan-skel.l: Adjust to these changes.
3354         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3355         (LOCATION_PRINT, skel_control_t): New.
3356
3357 2001-12-30  Akim Demaille  <akim@epita.fr>
3358
3359         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3360         replace `gb' with BLANKS.
3361         * src/scan-skel.l: Adjust.
3362
3363 2001-12-30  Akim Demaille  <akim@epita.fr>
3364
3365         * src/system.h: We don't need nor want bcopy.
3366         Throw away MS-DOS crap: we don't need getpid.
3367         * configure.in: We don't need strndup.  It was even causing
3368         problems: because Flex includes the headers *before* us,
3369         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3370         not visible.
3371         * lib/xstrndup.c: New.
3372         * src/scan-skel.l: Use it.
3373         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3374         * src/parse-skel.y: Use %directives instead of #defines.
3375
3376 2001-12-30  Akim Demaille  <akim@epita.fr>
3377
3378         * src/skeleton.h: New.
3379         * src/output.c (output_parser, output_master_parser): Remove, dead
3380         code.
3381         * src/output.h (get_lines_number, actions_output, guards_output)
3382         (token_definitions_output): Prototype them.
3383         * src/parse-skel.y: Add the license notice.
3384         Include output.h and skeleton.h.
3385         (process_skeleton): Returns void, and takes a single parameter.
3386         * src/scan-skel.l: Add the license notice.
3387         Include skeleton.h.
3388         Don't use %option yylineno: it seems that then Flex imagines
3389         REJECT has been used, and therefore it won't reallocate its
3390         buffers (which makes no other sense to me than a bug).  It results
3391         in warnings for `unused: yy_flex_realloc'.
3392
3393 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
3394
3395         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3396         (MUSCLE_INSERT_PREFIX): ...to there.
3397         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3398         (MUSCLE_INSERT_PREFIX): Move from here...
3399
3400         * src/bison.hairy: Add a section directive.  Put braces around muscle
3401         names.  This parser skeleton is still broken, but Bison should not
3402         choke on a bad muscle 'syntax'.
3403         * src/bison.simple: Add a section directive.  Put braces around muscle
3404         names.
3405
3406         * src/files.h (strsuffix, stringappend): Add declarations.
3407         (tab_extension): Add declaration.
3408         (short_base_name): Add declaration.
3409
3410         * src/files.c (strsuffix, stringappend): No longer static.  These
3411         functions are used in the skeleton parser.
3412         (tab_extension): New.
3413         (compute_base_names): Use the computations done in this function
3414         to guess if the generated parsers should have '.tab' in their
3415         names.
3416         (short_base_name): No longer static.
3417
3418         * src/output.c (output_skeleton): New.
3419         (output): Disable call to output_master_parser, and give a try to
3420         a new skeleton handling system.
3421         (guards_output, actions_output): No longer static.
3422         (token_definitions_output, get_lines_number): No longer static.
3423
3424         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3425
3426         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3427         parse-skel.y.
3428
3429         * src/parse-skel.y: New file.
3430         * src/scan-skel.l: New file.
3431
3432 2001-12-29  Akim Demaille  <akim@epita.fr>
3433
3434         %name-prefix is broken.
3435
3436         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3437         Adjust all dependencies.
3438         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3439         %name-prefix.
3440
3441         Renaming yylval but not yylloc is not consistent.  Now we do.
3442
3443         * src/bison.simple: Prefix yylloc if used.
3444         * doc/bison.texinfo (Decl Summary): Document that.
3445
3446 2001-12-29  Akim Demaille  <akim@epita.fr>
3447
3448         * doc/bison.texinfo: Promote `%long-directive' over
3449         `%long_directive'.
3450         Remove all references to fixed-output-files, yacc is enough.
3451
3452 2001-12-29  Akim Demaille  <akim@epita.fr>
3453
3454         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3455         user prologue.  These are defaults.
3456         * tests/actions.at (Mid-rule actions): Make sure the user can
3457         define YYDEBUG and YYERROR_VERBOSE.
3458
3459 2001-12-29  Akim Demaille  <akim@epita.fr>
3460
3461         * src/output.c (header_output): Don't forget to export YYLTYPE and
3462         yylloc.
3463         * tests/headers.at (export YYLTYPE): New, make sure it does.
3464         * tests/regression.at (%union and --defines, Invalid CPP headers):
3465         Move to...
3466         * tests/headers.at: here.
3467
3468 2001-12-29  Akim Demaille  <akim@epita.fr>
3469
3470         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3471
3472 2001-12-29  Akim Demaille  <akim@epita.fr>
3473
3474         * tests/actions.at (Mid-rule actions): Output on a single line
3475         instead of several.
3476
3477 2001-12-29  Akim Demaille  <akim@epita.fr>
3478
3479         * doc/bison.texinfo: Formatting changes.
3480
3481 2001-12-29  Akim Demaille  <akim@epita.fr>
3482
3483         Don't store the token defs in a muscle, just be ready to output it
3484         on command.  Now possible via `symbols'.  Fixes a memory leak.
3485
3486         * src/output.c (token_definitions_output): New.
3487         (output_parser, header_output): Use it.
3488         * src/reader.c (symbols_save): Remove.
3489
3490 2001-12-29  Akim Demaille  <akim@epita.fr>
3491
3492         * src/bison.simple: Do not provide a default for YYSTYPE and
3493         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3494         default.
3495
3496 2001-12-29  Akim Demaille  <akim@epita.fr>
3497
3498         Mid-rule actions are simply... ignored!
3499
3500         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3501         the empty-rule associated to the dummy symbol, not to the host
3502         rule.
3503         * tests/actions.at (Mid-rule actions): New.
3504
3505 2001-12-29  Akim Demaille  <akim@epita.fr>
3506
3507         Memory leak.
3508
3509         * src/reader.c (reader): Free grammar.
3510
3511 2001-12-29  Akim Demaille  <akim@epita.fr>
3512
3513         Memory leak.
3514
3515         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3516         since it allocates it for each state, although only one is needed.
3517         (allocate_storage): Do it here.
3518
3519 2001-12-29  Akim Demaille  <akim@epita.fr>
3520
3521         * src/options.h, src/options.c (create_long_option_table): Rename
3522         as...
3523         (long_option_table_new): this, with a clearer prototype.
3524         (percent_table): Remove, unused,
3525         * src/getargs.c (getargs): Adjust.
3526
3527 2001-12-29  Akim Demaille  <akim@epita.fr>
3528
3529         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3530         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3531         as states.
3532
3533 2001-12-29  Akim Demaille  <akim@epita.fr>
3534
3535         * src/lalr.c (build_relations): Rename `states' as `states1'.
3536         Sorry, I don't understand exactly what it is, no better name...
3537
3538 2001-12-29  Akim Demaille  <akim@epita.fr>
3539
3540         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3541         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3542         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3543         as rules.
3544
3545 2001-12-29  Akim Demaille  <akim@epita.fr>
3546
3547         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3548         ago.
3549
3550 2001-12-29  Akim Demaille  <akim@epita.fr>
3551
3552         * src/reader.c, src/reader.h (user_toknums): Remove.
3553         Adjust all users to use symbols[i]->user_token_number.
3554
3555 2001-12-29  Akim Demaille  <akim@epita.fr>
3556
3557         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3558         Adjust all users to use symbols[i]->prec or ->assoc.
3559
3560 2001-12-29  Akim Demaille  <akim@epita.fr>
3561
3562         * src/reader.c, src/reader.h (tags): Remove.
3563         Adjust all users to use symbols[i]->tag.
3564
3565 2001-12-29  Akim Demaille  <akim@epita.fr>
3566
3567         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3568         and rule_table.
3569         * src/reader.c (packsymbols): Fill this table.
3570         Drop sprec.
3571         * src/conflicts.c (resolve_sr_conflict): Adjust.
3572         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3573         single table.
3574         Use symbols[i]->tag instead of tags[i].
3575
3576 2001-12-29  Akim Demaille  <akim@epita.fr>
3577
3578         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3579         In addition, put a comment in there, to replace...
3580         * tests/regression.at (%union and C comments): Remove.
3581
3582 2001-12-29  Akim Demaille  <akim@epita.fr>
3583
3584         * tests/regression.at (Web2c Actions): Blindly move the actual
3585         output as expected output.  The contents *seem* right to me, but I
3586         can't pretend reading perfectly parser tables...  Nonetheless, all
3587         the other tests pass correctly, the table look OK, even though the
3588         presence of `$axiom' is to be noted: AFAICS it is useless (but
3589         harmless).
3590
3591 2001-12-29  Akim Demaille  <akim@epita.fr>
3592
3593         * src/reader.c (readgram): Don't add the rule 0 if there were no
3594         rules read.  In other words, add it _after_ having performed
3595         grammar sanity checks.
3596         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3597
3598 2001-12-29  Akim Demaille  <akim@epita.fr>
3599
3600         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3601         visible, and some states have now a different number.
3602
3603 2001-12-29  Akim Demaille  <akim@epita.fr>
3604
3605         * src/reader.c (readgram): Bind the initial rule's lineno to that
3606         of the first rule.
3607         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3608         (Solved SR Conflicts): Adjust rule 0's line number.
3609
3610 2001-12-29  Akim Demaille  <akim@epita.fr>
3611
3612         Fix the `GAWK Grammar' failure.
3613
3614         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3615         the reductions of the first state which was mistakenly confused
3616         with the final state because precisely final_state was initialized
3617         to 0.
3618         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3619         now noticed by Bison.
3620         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3621         have a reduction on $default.
3622
3623 2001-12-29  Akim Demaille  <akim@epita.fr>
3624
3625         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3626         rule line numbers.
3627         * src/closure.c (print_closure): Likewise.
3628         * src/derives.c (print_derives): Likewise.
3629         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3630         now.
3631
3632 2001-12-29  Akim Demaille  <akim@epita.fr>
3633
3634         * src/lalr.c (lookaheads_print): New.
3635         (lalr): Call it when --trace-flag.
3636         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3637         are dumped.
3638
3639 2001-12-29  Akim Demaille  <akim@epita.fr>
3640
3641         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3642         when walking through ritem, even via rule->rhs.
3643         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3644         (useful_production, useless_nonterminals): Likewise.
3645         (reduce_grammar_tables): Likewise, plus update nritems.
3646         * src/nullable.c (set_nullable): Likewise.
3647         * src/lalr.c (build_relations): Likewise.
3648         * tests/sets.at (Nullable): Adjust.
3649         Fortunately, now, the $axiom is no longer nullable.
3650
3651 2001-12-29  Akim Demaille  <akim@epita.fr>
3652
3653         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3654         the 0-sentinel.
3655         * src/gram.c (ritem_longest_rhs): Likewise.
3656         * src/reduce.c (nonterminals_reduce): Likewise.
3657         * src/print_graph.c (print_graph): Likewise.
3658         * src/output.c (output_rule_data): Likewise.
3659         * src/nullable.c (set_nullable):  Likewise.
3660
3661 2001-12-29  Akim Demaille  <akim@epita.fr>
3662
3663         * src/output.c: Comment changes.
3664
3665 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3666
3667         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3668         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3669         Sparc, as they were causing more porting problems than the
3670         (minor) performance improvement was worth.
3671
3672         Also, catch up with 1.31's YYSTD.
3673
3674 2001-12-27  Akim Demaille  <akim@epita.fr>
3675
3676         * src/output.c (output_gram): Rely on nritems, not the
3677         0-sentinel.  See below.
3678         Use -1 as separator, not 0.
3679         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3680         Rely on -1 as separator in yyrhs, instead of 0.
3681         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3682         twice `Now at end of input', therefore there are two lines less to
3683         expect.
3684
3685 2001-12-27  Akim Demaille  <akim@epita.fr>
3686
3687         * tests/regression.at (Unresolved SR Conflicts):
3688         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3689         below.
3690
3691 2001-12-27  Akim Demaille  <akim@epita.fr>
3692
3693         * src/LR0.c (new_state): Recognize the final state by the fact it
3694         is reached by eoftoken.
3695         (insert_start_shifting_state, insert_eof_shifting_state)
3696         (insert_accepting_state, augment_automaton): Remove, since now
3697         these states are automatically computed from the initial state.
3698         (generate_states): Adjust.
3699         * src/print.c: When reporting a rule number to the user, substract
3700         1, so that the axiom rule is rule 0, and the first user rule is 1.
3701         * src/reduce.c: Likewise.
3702         * src/print_graph.c (print_core): For the time being, just as for
3703         the report, depend upon --trace-flags to dump the full set of
3704         items.
3705         * src/reader.c (readgram): Once the grammar read, insert the rule
3706         0: `$axiom: START-SYMBOL $'.
3707         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3708         number of the states has changed (the final state is no longer
3709         necessarily the last), catch up.
3710
3711 2001-12-27  Akim Demaille  <akim@epita.fr>
3712
3713         Try to make the use of the eoftoken valid.  Given that its value
3714         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3715         is used instead of > 0 where appropriate, (ii), depend upon nritems
3716         instead of the 0-sentinel.
3717
3718         * src/gram.h, src/gram.c (nritems): New.
3719         Expected to be duplication of nitems, but for the time being...
3720         * src/reader.c (packgram): Assert nritems and nitems are equal.
3721         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3722         * src/closure.c (print_closure, print_fderives): Likewise.
3723         * src/gram.c (ritem_print): Likewise.
3724         * src/print.c (print_core, print_grammar): Likewise.
3725         * src/print_graph.c: Likewise.
3726
3727 2001-12-27  Akim Demaille  <akim@epita.fr>
3728
3729         * src/main.c (main): If there are complains after grammar
3730         reductions, then output the report anyway if requested, then die.
3731         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3732         * src/reader.c (eoftoken): New.
3733         (parse_token_decl): If the token being defined has value `0', it
3734         is the eoftoken.
3735         (packsymbols): No longer hack `tags' to insert `$' by hand.
3736         Be sure to preserve the value of the eoftoken.
3737         (reader): Make sure eoftoken is defined.
3738         Initialize nsyms to 0: now eoftoken is created just like the others.
3739         * src/print.c (print_grammar): Don't special case the eof token.
3740         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3741         lie anyway, albeit pleasant.
3742         * tests/calc.at: Exercise error messages with eoftoken.
3743         Change the grammar so that empty input is invalid.
3744         Adjust expectations.
3745         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3746
3747 2001-12-27  Akim Demaille  <akim@epita.fr>
3748
3749         * configure.in: Check the protos of strchr ans strspn.
3750         Replace strchr if needed.
3751         * src/system.h: Provide the protos of strchr, strspn and memchr if
3752         missing.
3753         * lib/strchr.c: New.
3754         * src/reader.c (symbols_save): Use strchr.
3755
3756 2001-12-27  Akim Demaille  <akim@epita.fr>
3757
3758         * src/print.c, src/print_graph.c (escape): New.
3759         Use it to quote the TAGS outputs.
3760         * src/print_graph.c (print_state): Now errors are in red, and
3761         reductions in green.
3762         Prefer high to wide: output the state number on a line of its own.
3763
3764 2001-12-27  Akim Demaille  <akim@epita.fr>
3765
3766         * src/state.h, src/state.c (reductions_new): New.
3767         * src/LR0.c (set_state_table): Let all the states have a
3768         `reductions', even if reduced to 0.
3769         (save_reductions): Adjust.
3770         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

3772         * src/output.c (action_row): Adjust.
3773
3774 2001-12-27  Akim Demaille  <akim@epita.fr>
3775
3776         * src/state.h, src/state.c (errs_new, errs_dup): New.
3777         * src/LR0.c (set_state_table): Let all the states have an errs,
3778         even if reduced to 0.
3779         * src/print.c (print_errs, print_reductions): Adjust.
3780         * src/output.c (output_actions, action_row): Adjust.
3781         * src/conflicts.c (resolve_sr_conflict): Adjust.
3782
3783 2001-12-27  Akim Demaille  <akim@epita.fr>
3784
3785         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3786
3787 2001-12-27  Akim Demaille  <akim@epita.fr>
3788
3789         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3790         * src/print.c: here.
3791         (lookaheadset, shiftset): New, used as additional storage by
3792         print_reductions.
3793         (print_results): Adjust.
3794         (print_shifts, print_gotos, print_errs): New, extracted from...
3795         (print_actions): here.
3796         * src/print_graph.c (print_actions): Remove dead code.
3797
3798 2001-12-27  Akim Demaille  <akim@epita.fr>
3799
3800         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3801         `$n' and `@n'.
3802
3803 2001-12-27  Akim Demaille  <akim@epita.fr>
3804
3805         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3806         (build_relations): Adjust.
3807
3808 2001-12-27  Akim Demaille  <akim@epita.fr>
3809
3810         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3811         duplication.
3812
3813 2001-12-27  Akim Demaille  <akim@epita.fr>
3814
3815         * src/reader.c (packgram): Catch nitems overflows.
3816
3817 2001-12-27  Akim Demaille  <akim@epita.fr>
3818
3819         * src/files.c, src/files.h (guard_obstack): Remove.
3820         * src/output.c (output): Adjust.
3821         * src/reader.c (parse_braces): New, factoring...
3822         (copy_action, copy_guard): these two which are renamed as...
3823         (parse_action, parse_guard): these.
3824         As a voluntary consequence, using braces around guards is now
3825         mandatory.
3826
3827 2001-12-27  Akim Demaille  <akim@epita.fr>
3828
3829         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3830         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3831         members.
3832         (symbol_list_new): Adjust.
3833         (copy_action): action_line is the first line, not the last.
3834         (copy_guard): Just as for actions, store the `action' only, not
3835         the switch/case/break flesh.
3836         Don't parse the user action that might follow the guard, let...
3837         (readgram): do it, i.e., now, there can be an action after a
3838         guard.
3839         In other words the guard is just explicitly optional.
3840         (packgram): Adjust.
3841         * src/output.c (guards_output): New.
3842         (output_parser): Call it when needed.
3843         (output): Also free the guard and attrs obstacks.
3844         * src/files.c, src/files.h (obstack_save): Remove.
3845         (output_files): Remove.
3846         As a result, if one needs the former `.act' file, using an
3847         appropriate skeleton which requires actions and guards is now
3848         required.
3849         * src/main.c (main): Adjust.
3850         * tests/semantic.at: New.
3851         * tests/regression.at: Use `input.y' as input file name.
3852         Avoid 8+3 problems by requiring input.c when the test needs the
3853         parser.
3854
3855 2001-12-27  Akim Demaille  <akim@epita.fr>
3856
3857         * src/reader.c (symbol_list_new): Be sure to initialize all the
3858         fields.
3859
3860 2001-12-27  Akim Demaille  <akim@epita.fr>
3861
3862         All the hacks using a final pseudo state are now useless.
3863
3864         * src/LR0.c (set_state_table): state_table holds exactly nstates.
3865         * src/lalr.c (nLA): New.
3866         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3867         instead of lookaheadsp from the pseudo state (nstate + 1).
3868
3869 2001-12-27  Akim Demaille  <akim@epita.fr>
3870
3871         * src/output.c (action_row, token_actions): Use a state_t instead
3872         of a integer, and nlookaheads instead of the following state's
3873         lookaheadsp.
3874
3875 2001-12-27  Akim Demaille  <akim@epita.fr>
3876
3877         * src/conflicts.c (log_resolution, flush_shift)
3878         (resolve_sr_conflict, set_conflicts, solve_conflicts)
3879         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3880         (conflicts_print, print_reductions): Use a state_t instead of an
3881         integer when referring to a state.
3882         As much as possible, depend upon nlookaheads, instead of the
3883         `lookaheadsp' member of the following state (since lookaheads of
3884         successive states are successive, the difference between state n + 1
3885         and n served as the number of lookaheads for state n).
3886         * src/lalr.c (add_lookback_edge): Likewise.
3887         * src/print.c (print_core, print_actions, print_state)
3888         (print_results): Likewise.
3889         * src/print_graph.c (print_core, print_actions, print_state)
3890         (print_graph): Likewise.
3891         * src/conflicts.h: Adjust.
3892
3893 2001-12-27  Akim Demaille  <akim@epita.fr>
3894
3895         * src/bison.hairy: Formatting/comment changes.
3896         ANSIfy.
3897         Remove `register' indications.
3898         Add plenty of `static'.
3899
3900 2001-12-27  Akim Demaille  <akim@epita.fr>
3901
3902         * src/output.c (prepare): Drop the muscle `ntbase' which
3903         duplicates ntokens.
3904         * src/bison.simple: Formatting/comment changes.
3905         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3906         is an undocumented synonym.
3907
3908 2001-12-22  Akim Demaille  <akim@epita.fr>
3909
3910         * src/output.c (output_table_data): Change the prototype to use
3911         `int' for array ranges: some invocations do pass an int, not a
3912         short.
3913         Reported by Wayne Green.

3918         Reported by Mike Castle.
3919
3920         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
3921         * tests/regression.at (Web2c): Rename as...
3922         (Web2c Report): this.
3923         (Web2c Actions): New.
3924
3925 2001-12-22  Akim Demaille  <akim@epita.fr>
3926
3927         Reductions in web2c.y are improperly reported.

3929
3930         * src/conflicts.c (print_reductions): Fix.
3931         * tests/regression.at (Web2c): New.
3932
3933 2001-12-18  Akim Demaille  <akim@epita.fr>
3934
3935         Some host fail on `assert (!"foo")', which expands to
3936         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3937         Reported by Nelson Beebee.
3938
3939         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3940         `#define it_succeeded 0' and `assert (it_succeeded)'.
3941
3942 2001-12-17  Marc Autret  <autret_m@epita.fr>
3943
3944         * src/bison.simple: Don't hard code the skeleton line and filename.
3945         * src/output.c (output_parser): Rename 'line' as 'output_line'.
3946         New line counter 'skeleton_line' (skeleton-line muscle).
3947
3948 2001-12-17  Paul Eggert  <eggert@twinsun.com>
3949
3950         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3951         YYDEBUG must be defined to a nonzero value.
3952
3953         * src/bison.simple (yytname): Do not assume that the user defines
3954         YYDEBUG to a properly parenthesized expression.
3955
3956 2001-12-17  Akim Demaille  <akim@epita.fr>
3957
3958         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3959         nlookaheads is a new member.

3966
3967         * src/files.h, src/files.c (open_files, close_files): Remove.
3968         * src/main.c (main): Don't open/close files, nor invoke lex_free,
3969         let...
3970         * src/reader.c (reader): Do it.
3971
3972 2001-12-17  Akim Demaille  <akim@epita.fr>
3973
3974         * src/conflicts.c (print_reductions): Formatting changes.

3983
3984         * src/output.c (output_obstack): Be static and rename as...

3986         output_obstack.
3987         * src/reader.h (muscle_obstack): Move to...
3988         * src/output.h: here, since it's defined in output.c.
3989
3990 2001-12-17  Akim Demaille  <akim@epita.fr>
3991
3992         * src/output.c (action_row, save_column, default_goto)
3993         (sort_actions, matching_state, pack_vector): Better variable
3994         locality.
3995

4009
4010         * src/output.c (actions_output): Fix. When we use %no-lines,
4011         there is one less line per action.
4012
4013 2001-12-16  Marc Autret  <autret_m@epita.fr>
4014
4015         * src/bison.simple: Remove a useless #line directive.
4016         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4017         * src/output.c (get_lines_number): New.
4018         (output_parser): Adjust, now takes care about the lines of a
4019         output muscles.
4020         Fix line numbering.
4021         (actions_output): Computes the number of lines taken by actions.
4022         (output_master_parser): Insert new skeleton which is the name of
4023         the output parser file name.
4024
4025 2001-12-15  Marc Autret  <autret_m@epita.fr>

4032
4033 2001-12-15  Akim Demaille  <akim@epita.fr>
4034
4035         Make `make distcheck' work.
4036
4037         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4038         system.h which uses libgettext.h.
4039
4040 2001-12-15  Akim Demaille  <akim@epita.fr>
4041
4042         * src/nullable.c (set_nullable): Useless rules must be skipped,
4043         otherwise, since we range over their symbols, we might look at a
4044         nonterminal which no longer ``exists'', i.e., it is not counted in
4045         `nvars', hence we overflow our arrays.
4046
4047 2001-12-15  Akim Demaille  <akim@epita.fr>
4048
4049         The header can also be produced directly, without any obstack!

4053         (compute_header_macro): Global.
4054         (defines_obstack_save): Remove.
4055         * src/reader.c (parse_union_decl): No longer output to
4056         defines_obstack: its content can be found in the `stype' muscle
4057         anyway.
4058         (output_token_translations): Merge into...
4059         (symbols_output): this.

4066 2001-12-15  Akim Demaille  <akim@epita.fr>
4067
4068         * src/reader.c (parse_union_decl): Instead of handling two obstack
4069         simultaneously, use one to define the `stype' muscle, and use the
4070         value of the latter to fill defines_obstack.
4071         (copy_comment): Remove.
4072         (copy_comment2): Work for a single obstack.
4073         Rename as...

4080
4081 2001-12-15  Akim Demaille  <akim@epita.fr>
4082
4083         Still making progress in separating Bison into (i) input, (ii)
4084         process, (iii) output: now we can directly output the parser file
4085         without using table_obstack at all.
4086
4087         * src/files.c, src/files.h (table_obstack): Bye bye.
4088         (parser_file_name): New.
4089         * src/files.c (compute_output_file_names): Compute it.
4090         * src/output.c (actions_output, output_parser)
4091         (output_master_parser): To a file instead of an obstack.
4092
4093 2001-12-15  Akim Demaille  <akim@epita.fr>
4094
4095         Attach actions to rules, instead of pre-outputting them to
4096         actions_obstack.
4097
4098         * src/gram.h (rule_t): action and action_line are new members.
4099         * src/reader.c (symbol_list): Likewise.
4100         (copy_action): Save the actions within the rule.
4101         (packgram): Save them in rule_table.
4102         * src/output.c (actions_output): New.
4103         (output_parser): Use it on `%%actions'.
4104         (output_rule_data): Don't free rule_table.
4105         (output): Do it.
4106         (prepare): Don't save the `action' muscle.
4107         * src/bison.simple: s/%%action/%%actions/.
4108
4109 2001-12-15  Akim Demaille  <akim@epita.fr>
4110
4111         * src/reader.c (copy_action): When --yacc, don't append a `;'
4112         to the user action: let it fail if lacking.
4113         Suggested by Arnold Robbins and Tom Tromey.
4114
4115 2001-12-14  Akim Demaille  <akim@epita.fr>
4116
4117         * src/lex.c (literalchar): Simply return the char you decoded, non
4118         longer mess around with obstacks and int pointers.
4119         Adjust all callers.
4120
4121 2001-12-14  Akim Demaille  <akim@epita.fr>
4122
4123         * src/lex.c (literalchar): Don't escape the special characters,
4124         just decode them, and keep them as char (before, eol was output as
4125         the 2 char string `\n' etc.).
4126         * src/output.c (output_rule_data): Use quotearg to output the
4127         token strings.
4128
4129 2001-12-13  Paul Eggert  <eggert@twinsun.com>
4130
4131         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4132         Do not infringe on the global user namespace when using C++.
4133         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4134         All uses of `fprintf' and `stderr' changed.
4135
4136         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4137
4138 2001-12-13  Akim Demaille  <akim@epita.fr>
4139
4140         The computation of nullable is broken: it doesn't handle empty
4141         RHS's properly.
4142
4143         * tests/torture.at (GNU AWK Grammar): New.
4144         * tests/sets.at (Nullable): New.
4145         * src/nullable.c (set_nullable): Instead of blindly looping over
4146         `ritems', loop over the rules, and then over their rhs's.
4147
4148         Work around Autotest bugs.
4149
4150         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4151         frame, because Autotest understand lines starting with a `+' as
4152         traces from the shell.  Then, they are not processed properly.
4153         Admittedly an Autotest bug, but we don't have time to wait for
4154         Autotest to catch up.
4155         * tests/regression.at (Broken Closure): Adjust to the new table
4156         frames.
4157         Move to...
4158         * tests/sets.at: here.
4159
4160 2001-12-13  Akim Demaille  <akim@epita.fr>
4161
4162         * src/closure.c (closure): Use nrules instead of playing tricks
4163         with BITS_PER_WORD.
4164
4165 2001-12-13  Akim Demaille  <akim@epita.fr>
4166
4167         * src/print.c (print_actions): Output the handling of `$' as the
4168         traces do: shifting the token EOF.  Before EOF was treated as a
4169         nonterminal.
4170         * tests/regression.at: Adjust some tests.
4171         * src/print_graph.c (print_core): Complete the set of items via
4172         closure.  The next-to-final and final states are still unsatisfying,
4173         but that's to be addressed elsewhere.
4174         No longer output the rule numbers, but do output the state number.
4175         A single loop for the shifts + gotos is enough, but picked a
4176         distinct color for each.
4177         (print_graph): Initialize and finalize closure.
4178
4179 2001-12-13  Akim Demaille  <akim@epita.fr>
4180
4181         * src/reader.c (readgram): Remove dead code, an strip useless
4182         braces.
4183         (get_type): Remove, unused.
4184
4185 2001-12-12  Akim Demaille  <akim@epita.fr>
4186
4187         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4188         on that of lib/error.c.
4189
4190 2001-12-12  Akim Demaille  <akim@epita.fr>
4191
4192         Some hosts don't like `/' in includes.
4193
4194         * src/system.h: Include libgettext.h without qualifying the path.
4195         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4196         $(top_srcdir).
4197
4198 2001-12-11  Marc Autret  <autret_m@epita.fr>
4199
4200         * src/output.c (output_parser): Remove useless muscle.
4201
4202 2001-12-11  Marc Autret  <autret_m@epita.fr>
4203
4204         * src/bison.simple: Remove #line just before %%epilogue. It
4205         is now handled in ...
4206         * src/reader.c (read_additionnal_code): Add the output of a
4207         #line for the epilogue.
4208
4209 2001-12-10  Marc Autret  <autret_m@epita.fr>
4210
4211         * src/reader.c (copy_definition): Re-use CPP-outed code which
4212         replace precedent remove.
4213         * src/bison.simple: Remove #line before %%prologue because
4214         %%input-line is wrong at this time.
4215
4216 2001-12-10  Marc Autret  <autret_m@epita.fr>
4217
4218         * src/reader.c (symbols_output): Clean up.
4219         * src/output.c (output_gram, output): Clean up.
4220
4221 2001-12-10  Akim Demaille  <akim@epita.fr>
4222
4223         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
4224         * src/LR0.c (set_state_table): here.
4225         * src/lalr.c (lalr): Call it.
4226
4227 2001-12-10  Akim Demaille  <akim@epita.fr>
4228
4229         * src/state.h (shifts): Remove the `number' member: shifts are
4230         attached to state, hence no longer need to be labelled with a
4231         state number.
4232
4233 2001-12-10  Akim Demaille  <akim@epita.fr>
4234
4235         Now that states have a complete set of members, the linked list of
4236         shifts is useless: just fill directly the state's shifts member.
4237
4238         * src/state.h (shifts): Remove the `next' member.
4239         * src/LR0.c (first_state, last_state): Remove.
4240         Adjust the callers.
4241         (augment_automaton): Don't look for the shifts that must be added
4242         a shift on EOF: it is those of the state we looked for!  But now,
4243         since shifts are attached, it is no longer needed to looking
4244         merely by its id: its number.
4245
4246 2001-12-10  Akim Demaille  <akim@epita.fr>
4247
4248         * src/LR0.c (augment_automaton): Better variable locality.
4249         Remove an impossible branch: if there is a state corresponding to
4250         the start symbol being shifted, then there is shift for the start
4251         symbol from the initial state.
4252
4253 2001-12-10  Akim Demaille  <akim@epita.fr>
4254
4255         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4256         only when appropriate: when insert_start_shifting_state' is not
4257         invoked.
4258         * tests/regression.at (Rule Line Numbers): Adjust.
4259
4260 2001-12-10  Akim Demaille  <akim@epita.fr>
4261
4262         * src/LR0.c (augment_automaton): Now that all states have shifts,
4263         merge the two cases addition shifts to the initial state.
4264
4265 2001-12-10  Akim Demaille  <akim@epita.fr>
4266
4267         * src/lalr.c (set_state_table): Move to...
4268         * src/LR0.c: here.
4269         * src/lalr.c (lalr): Don't call it...
4270         * src/LR0.c (generate_states): do it.
4271         * src/LR0.h (first_state): Remove, only the table is used.
4272
4273 2001-12-10  Akim Demaille  <akim@epita.fr>
4274
4275         * src/LR0.h (first_shift, first_reduction): Remove.
4276         * src/lalr.c: Don't use first_shift: find shifts through the
4277         states.
4278
4279 2001-12-10  Akim Demaille  <akim@epita.fr>
4280
4281         * src/LR0.c: Attach shifts to states as soon as they are
4282         computed.
4283         * src/lalr.c (set_state_table): Instead of assigning shifts to
4284         state, just assert that the mapping was properly done.
4285
4286 2001-12-10  Akim Demaille  <akim@epita.fr>
4287
4288         * src/LR0.c (insert_start_shift): Rename as...
4289         (insert_start_shifting_state): this.
4290         (insert_eof_shifting_state, insert_accepting_state): New.
4291         (augment_automaton): Adjust.
4292         Better locality of the variables.
4293         When looking if the start_symbol is shifted from the initial
4294         state, using `while (... symbol != start_symbol ...)' sounds
4295         better than `while (... symbol < start_symbol ...)': If fail
4296         to see how the order between symbols could be relevant!
4297
4298 2001-12-10  Akim Demaille  <akim@epita.fr>
4299
4300         * src/getargs.h: Don't declare `spec_name_prefix' and
4301         `spec_file_prefix', declared by src/files.h.
4302         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4303         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4304         * src/output.c (prepare): Adjust.
4305         * src/reader.c (symbols_output): Likewise.
4306         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4307
4308 2001-12-10  Akim Demaille  <akim@epita.fr>
4309
4310         * src/muscle_tab.c (muscle_init): NULL is a better default than
4311         `"0"'.
4312
4313 2001-12-10  Akim Demaille  <akim@epita.fr>
4314
4315         * src/reader.c (reader): Calling symbols_output once is enough.
4316
4317 2001-12-10  Akim Demaille  <akim@epita.fr>
4318
4319         Now that states have a complete set of members, the linked list of
4320         reductions is useless: just fill directly the state's reductions
4321         member.
4322
4323         * src/state.h (struct reductions): Remove member `number' and
4324         `next'.
4325         * src/LR0.c (first_reduction, last_reduction): Remove.
4326         (save_reductions): Don't link the new reductions, store them in
4327         this_state.
4328         * src/lalr.c (set_state_table): No need to attach reductions to
4329         states, it's already done.
4330         * src/output.c (output_actions): No longer free the shifts, then
4331         the reductions, then the states: free all the states and their
4332         members.
4333
4334 2001-12-10  Akim Demaille  <akim@epita.fr>
4335
4336         * src/options.c (OPTN, DRTV, BOTH): New.
4337         (option_table): Use them.
4338
4339         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4340         the job of system.h.
4341         * src/options.c: Don't include stdio.h and xalloc.h for the same
4342         reasons.
4343
4344 2001-12-10  Akim Demaille  <akim@epita.fr>
4345
4346         * src/output.c (output, prepare): Make sure the values of the
4347         muscles `action' and `prologue' are 0-terminated.
4348
4349 2001-12-10  Akim Demaille  <akim@epita.fr>
4350
4351         Clean up GCC warnings.
4352
4353         * src/reader.c (copy_action): `buf' is not used.
4354         (parse_skel_decl): Be static.
4355         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4356         * src/options.h (create_long_option_table): Have a real prototype.
4357         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4358         (hash_delete_at): Return const void *.
4359         Adjust casts to preserve the const.
4360
4361 2001-12-10  Akim Demaille  <akim@epita.fr>
4362
4363         * configure.in: Require 2.52g.
4364         M4 is not needed, but AUTOM4TE is.
4365         * m4/m4.m4: Remove.
4366         * tests/Makefile.am: Adjust.
4367
4368 2001-12-10  Akim Demaille  <akim@epita.fr>
4369
4370         One structure for states is enough, even though theoretically
4371         there are LR(0) states and LALR(1) states.
4372
4373         * src/lalr.h (state_t): Remove.
4374         (state_table): Be state_t **, not state_t *.
4375         * src/state.h (core, CORE_ALLOC): Rename as...
4376         (state_t, STATE_ALLOC): this.
4377         Add the LALR(1) members: shifts, reductions, errs.
4378         * src/LR0.c (state_table): Rename as...
4379         (state_hash): this, to avoid name clashes with the global
4380         `state_table'.
4381         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4382         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
4383
4384 2001-12-10  Akim Demaille  <akim@epita.fr>
4385
4386         Bison dumps core on bash.y.
4387         Reported by Pascal Bart.
4388
4389         * src/warshall.c (bitmatrix_print): New.
4390         (TC): Use it.
4391         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4392         j must be the outer loop.
4393         * tests/regression.at (Broken Closure): New.
4394
4395 2001-12-05  Akim Demaille  <akim@epita.fr>
4396
4397         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4398         its argument.
4399         Reported by Peter Hámorský.
4400
4401 2001-12-05  Akim Demaille  <akim@epita.fr>
4402
4403         * src/conflicts.c (err_table): Remove.
4404         (resolve_sr_conflict): Adjust.
4405         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4406         Rename as...
4407         (state_t.reductions, state_t.shifts): this.
4408
4409 2001-12-05  Akim Demaille  <akim@epita.fr>
4410
4411         * src/reduce.c (reduce_grammar_tables): No longer disable the
4412         removal of useless rules via CPP but via `if (0)', so that the
4413         compiler still check the code is valid.
4414         For instance, it should have noticed `rline' no longer exists: use
4415         the `line' member of rule_t.
4416         * src/gram.c (dummy, rline): Remove, unused.
4417
4418 2001-12-05  Akim Demaille  <akim@epita.fr>
4419
4420         * src/output.c (pack_vector): Use assert, not berror.
4421         * src/main.c (berror): Remove, unused.
4422
4423 2001-12-05  Akim Demaille  <akim@epita.fr>
4424
4425         New experimental feature: if --verbose --trace output all the
4426         items of a state, not only its kernel.
4427
4428         * src/print.c (print_core): If `trace_flag', then invoke closure
4429         before outputting the items of the state (print_core is no longer
4430         a correct name them).
4431         (print_results): Invoke new_closure/free_closure if needed.
4432
4433 2001-12-05  Akim Demaille  <akim@epita.fr>
4434
4435         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4436         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4437         (nitemset): for consistency with the rest of the project.
4438
4439 2001-12-05  Akim Demaille  <akim@epita.fr>
4440
4441         * src/closure.c (print_closure): Improve.
4442         (closure): Use it for printing input and output.
4443
4444 2001-12-05  Akim Demaille  <akim@epita.fr>
4445
4446         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4447         indexed by nonterminals.
4448
4449 2001-12-05  Akim Demaille  <akim@epita.fr>
4450
4451         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4452         what it was!).
4453         * src/warshall.h: Remove accidental duplication of the content.

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

4513
4514         * src/conflicts.c (print_reductions): Pessimize, but clarify.

4530         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
4531         * src/lalr.c: Use them.
4532
4533 2001-12-05  Akim Demaille  <akim@epita.fr>
4534
4535         * src/LR0.c (augment_automaton): Formatting changes.
4536         Better variable locality.
4537
4538 2001-12-05  Akim Demaille  <akim@epita.fr>
4539
4540         * src/lalr.c (matrix_print): New.
4541         (transpose): Use it.
4542         Use arrays instead of pointers.
4543
4544 2001-12-05  Akim Demaille  <akim@epita.fr>
4545
4546         * src/lalr.c (maxrhs): Move to...
4547         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4548         * src/lalr.c (build_relations): Adjust.
4549
4550 2001-12-05  Akim Demaille  <akim@epita.fr>
4551
4552         * src/lalr.c (transpose): Free the memory allocated to the
4553         argument, as it is replaced by the results by the unique caller.
4554         (build_relations): Merely invoke transpose: it handles the memory
4555         deallocation.
4556         Improve variable locality.
4557         Avoid variables used as mere abbreviations.
4558         (compute_lookaheads): Use arrays instead of pointers.
4559
4560 2001-12-05  Akim Demaille  <akim@epita.fr>
4561
4562         * src/lalr.c (initialize_F): Improve variable locality.
4563         Avoid variables used as mere abbreviations.
4564
4565 2001-12-05  Akim Demaille  <akim@epita.fr>
4566
4567         * src/derives.c (print_derives): Display the ruleno.
4568         * src/lalr.c (initialize_F, transpose): Better variable locality
4569         to improve readability.
4570         Avoid variables used as mere abbreviations.
4571
4572 2001-12-05  Akim Demaille  <akim@epita.fr>
4573
4574         * src/lalr.c (traverse): Use arrays instead of pointers.
4575
4576 2001-12-05  Akim Demaille  <akim@epita.fr>
4577
4578         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4579         the handling of squeue.
4580         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4581
4582 2001-12-05  Akim Demaille  <akim@epita.fr>
4583
4584         Because useless nonterminals are now kept alive (instead of being
4585         `destroyed'), we now sometimes examine them, and store information
4586         related to them.  Hence we need to know their number, and adjust
4587         memory allocations.
4588
4589         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4590         static.
4591         * src/LR0.c (allocate_itemsets): The memory allocated to
4592         `symbol_count' was used for two different purpose: once to count
4593         the number of occurrences of each symbol, and later reassigned to
4594         `shift_symbol', containing the symbol that can be shifted from a
4595         given state.
4596         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4597         only, and...
4598         (new_itemsets): Allocate `shift_symbol' here.
4599         (allocate_itemsets): symbol_count includes useless nonterminals.
4600         Make room for them.
4601         (free_storage): Use `free', not `XFREE', for pointers that cannot
4602         be null.
4603
4604 2001-12-05  Akim Demaille  <akim@epita.fr>
4605
4606         * src/nullable.c (set_nullable): Deobfuscate the handling of
4607         ritem.
4608         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4609
4610 2001-12-05  Akim Demaille  <akim@epita.fr>
4611
4612         * src/gram.c, src/gram.h (ritem_print): New.
4613         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4614         (This useless function was defined only to work around VMS linkers
4615         that can't handle compilation units with variables only).
4616         * src/reduce.c (dump_grammar): Use it to trace the construction of
4617         ritem.
4618
4619 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4620
4621         * src/bison.simple (union yyalloc): Change member names
4622         to be the same as the stack names.
4623         (yyparse): yyptr is now union yyalloc *, not char *.
4624         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4625         and may generate better code on some machines.
4626         (yystpcpy): Use prototype if __STDC__ is defined, not just
4627         if __cplusplus is defined.
4628
4629 2001-11-30  Akim Demaille  <akim@epita.fr>
4630
4631         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4632         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4633         Gettext doesn't compile cleanly, and dies with -Werror.
4634         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4635         Include WARNING_CFLAGS here.
4636         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4637         before being defined.
4638
4639 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4640
4641         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4642         First arg is int, not unsigned.
4643         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4644         (SIZE_MAX, UINT_MAX): New macros.
4645         (quotearg_n_options): Abort if N is negative.
4646         Avoid overflow check on hosts where size_t is 64 bits and int
4647         is 32 bits, as overflow is impossible there.
4648         Fix off-by-one typo that caused unnecessary reallocation.
4649
4650 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4651
4652         Name space cleanup in generated parser.
4653
4654         * doc/bison.texinfo (Bison Parser): Discuss system headers
4655         and their effect on the user name space.
4656
4657         * src/bison.simple:
4658         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4659         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4660         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4661
4662         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4663         on user names when possible.
4664
4665         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4666         Simplify test for whather <alloca.h> exists.
4667
4668         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4669
4670         (<stdio.h>): Include if YYDEBUG.
4671
4672         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4673         ! defined (yyoverflow) && ! defined (yymemcpy).
4674
4675         (yymemcpy, yyparse): Rename local variables as needed so that
4676         they all begin with 'yy'.
4677
4678         (yystrlen, yystpcpy): New functions.
4679
4680         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4681         All uses changed.
4682
4683         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4684         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4685         and YYSTACK_FREE instead of malloc and free.
4686
4687 2001-11-30  Akim Demaille  <akim@epita.fr>
4688
4689         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4690         before their first uses.
4691         (YYBISON, YYPURE): Move to the top of the output.
4692

4696
4697 2001-11-30  Akim Demaille  <akim@epita.fr>
4698
4699         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4700         if body instead of `;' to pacify GCC's warnings.
4701
4702 2001-11-30  Akim Demaille  <akim@epita.fr>
4703
4704         Instead of mapping the LHS of unused rules to -1, keep the LHS
4705         valid, but flag the rules as invalid.
4706
4707         * src/gram.h (rule_t): `useful' is a new member.
4708         * src/print.c (print_grammar): Adjust.
4709         * src/derives.c (set_derives): Likewise.
4710         * src/reader.c (packgram, reduce_output): Likewise.
4711         * src/reduce.c (reduce_grammar_tables): Likewise.
4712         * tests/reduce.at (Underivable Rules, Useless Rules): New.
4713

4715
4716         * src/reduce.c (reduce_output): Formatting changes.
4717         * src/print.c (print_results, print_grammar): Likewise.
4718         * tests/regression.at (Rule Line Numbers)
4719         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4720
4721 2001-11-30  Akim Demaille  <akim@epita.fr>
4722
4723         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4724         useless nonterminals, move them at the end of the symbol arrays.
4725         (reduce_output): Adjust.
4726         * tests/reduce.at (Useless Nonterminals): Adjust.
4727
4728 2001-11-30  Akim Demaille  <akim@epita.fr>
4729
4730         * src/reduce.c: Various comment/formatting changes.
4731         (nonterminals_reduce): New, extracted from...
4732         (reduce_grammar_tables): here.
4733         (reduce_grammar): Call nonterminals_reduce.
4734
4735 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4736
4737         * src/bison.simple (YYSTACK_REALLOC): Remove.
4738         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4739         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4740         New macros.
4741         (union yyalloc): New type.
4742         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4743         an arbitrary restriction on hosts where size_t is wider than int.
4744
4745         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4746         a parser stack overflow.  Allocate just one block of memory for all
4747         three stacks, instead of allocating three blocks; this typically is
4748         faster and reduces fragmentation.
4749
4750         Do not limit the number of items in the stack to a value that fits
4751         in 'int', as this is an arbitrary limit on hosts with 64-bit
4752         size_t and 32-bit int.
4753
4754 2001-11-29  Marc Autret  <autret_m@epita.fr>
4755
4756         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4757         of defining YYERROR_VERBOSE.
4758         [AT_DATA]: $4 is now out of C declarations in the prologue.
4759
4760 2001-11-28  Marc Autret  <autret_m@epita.fr>
4761
4762         * src/reader.c (parse_dquoted_param): New.
4763         (parse_skel_decl): Use it.
4764         * src/lex.h: Add its prototype.
4765         * src/lex.c (literalchar): Become not static.
4766
4767 2001-11-28  Marc Autret  <autret_m@epita.fr>
4768
4769         * src/output.h: And put its extern declaration here.
4770         * src/output.c (error_verbose): Define here.
4771         (prepare): Echo name modification.
4772         * src/getargs.h: Clean its extern declaration.
4773         * src/getargs.c (error_verbose_flag): Remove.
4774         (getargs): Remove case 'e'.
4775         * src/options.c (option_table): 'error-verbose' is now seen as simple
4776         percent option.
4777         Include output.h.
4778
4779         * src/reader.c (read_declarations): Remove case tok_include.
4780         (parse_include_decl): Remove.
4781         * src/lex.h (token_t): Remove tok_include.
4782         * src/options.c (option_table): 'include' is now a simple command line
4783         option.
4784
4785 2001-11-28  Marc Autret  <autret_m@epita.fr>
4786
4787         * src/bison.simple: Adjust muscle names.
4788         * src/muscle_tab.c (muscle_init): Also rename the muscles.
4789         * src/output.c (prepare): s/_/-/ for the muscles names.
4790         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
4791
4792 2001-11-28  Marc Autret  <autret_m@epita.fr>
4793

4800         (save_shifts, insert_start_shift, augment_automaton): Use it.
4801
4802 2001-11-28  Akim Demaille  <akim@epita.fr>
4803
4804         * src/closure.c (closure): `b' and `ruleno' denote the same value:
4805         keep ruleno only.
4806
4807 2001-11-28  Akim Demaille  <akim@epita.fr>
4808
4809         * src/closure.c (closure): Instead of looping over word in array
4810         then bits in words, loop over bits in array.
4811
4812 2001-11-28  Akim Demaille  <akim@epita.fr>

5179         * tests/calc.at, tests/output.at, tests/regression.at,
5180         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
5181         now the tests are run in private dirs, therefore AC_CLEANUP and
5182         family can be simplified to 0-ary.
5183         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
5184         use abs. path to find config.h.
5185         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
5186         stderr, there can be way too much random noise.

6594
6595 2001-01-18  Akim Demaille  <akim@epita.fr>

6602         Since we now use obstacks, more % directives can be enabled.
6603
6604         * src/lex.c (percent_table): Also accept `%yacc',
6605         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
6606         `%debug'.
6607         Handle the actions for `%semantic_parser' and `%pure_parser' here,
6608         instead of returning a token.

6610         * src/reader.c (read_declarations): Adjust.
6611         * src/files.c (open_files): Don't call `compute_base_names', don't
6612         compute `attrsfile' since they depend upon data which might be
6613         *in* the input file now.
6614         (output_files): Do it here.
6615         * src/output.c (output_headers): Document the fact that this patch

6641         FILE * parameters.
6642
6643 2000-12-20  Akim Demaille  <akim@epita.fr>
6644
6645         * src/files.c (open_files): Actually the `.output' file is based

6648
6649 2000-12-20  Akim Demaille  <akim@epita.fr>

6675         (stringappend): Be just like strcat but allocate.
6676         (base_names): Eve out from open_files.
6677         Try to simplify the rather hairy computation of base_name and
6678         short_base_name.
6679         (open_files): Use it.
6680         * tests/suite.at (Checking output file names): New test.

6698 2000-12-19  Akim Demaille  <akim@epita.fr>
6699
6700         Let the handling of the skeleton files be local to the procedures
6701         that use it.
6702
6703         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
6704         longer static.

6719
6720         * src/files.c (open_files): Yipee!  We no longer need all the code
6721         looking for `/tmp' since we have no tmp file.

6752         * lib/obstack.h: Formatting changes.
6753         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6754         prevents type checking.
6755         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6756         cast the value to (void *): assigning a `foo *' to a `void *'
6757         variable is valid.
6758         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

6794
6795 2000-11-07  Akim Demaille  <akim@epita.fr>
6796

6841         when there are no errors.

6951         Include the core of the sample provided by Piotr Gackiewicz.
6952         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
6953         properly.
6954
6955 2000-10-04  Akim Demaille  <akim@epita.fr>
6956
6957         * src/reader.c (parse_expect_decl): Keep `count' within the size
6958         of `buffer'.
6959         From Neil Booth.
6960
6961 2000-10-02  Paul Eggert  <eggert@twinsun.com>
6962
6963         * bison.s1 (yyparse): Assign the default value
6964         unconditionally, to avoid a GCC warning and make the parser a
6965         tad smaller.
6966
6967 2000-10-02  Akim Demaille  <akim@epita.fr>
6968
6969         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
6970         options.
6971
6972 2000-10-02  Akim Demaille  <akim@epita.fr>
6973
6974         * src/derives.c, src/print.c, src/reduce.c: To ease the
6975         translation, move some `\n' out of the translated strings.
6976
6977 2000-10-02  Akim Demaille  <akim@epita.fr>
6978
6979         The location tracking mechanism is precious for parse error
6980         messages.  Nevertheless, it is enabled only when `@n' is used in
6981         the grammar, which is a different issue (you can use it in error
6982         message, but not in the grammar per se).  Therefore, there should
6983         be another means to enable it.
6984
6985         * src/getargs.c (getargs): Support `--locations'.
6986         (usage): Report it.
6987         * src/getargs.h (locationsflag): Export it.
6988         * src/lex.c (percent_table): Support `%locations'.
6989         * src/reader.c (yylsp_needed): Remove this variable, now replaced
6990         with `locationsflag'.
6991         * doc/bison.texinfo: Document `--locations' and `%locations'.
6992         Sort the options.
6993         * tests/calc.m4: Test it.
6994
6995         For regularity of the names, replace each
6996         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6997         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6998         In addition replace each `flag' with `_flag'.
6999
7000 2000-10-02  Akim Demaille  <akim@epita.fr>
7001
7002         Also test parse error messages, including with YYERROR_VERBOSE.
7003
7004         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7005         associative).
7006         Use it to check the computations.
7007         Use it to check `nonassoc' is honored.
7008         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7009         `--yyerror-verbose'.
7010         (_AT_CHECK_CALC): Adjust to this option.
7011         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7012
7013 2000-10-02  Akim Demaille  <akim@epita.fr>
7014
7015         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
7016         the latter demonstrates a flaw in the handling of non debugging
7017         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7018         was used in order to simplify:
7019
7020         #if YYDEBUG
7021         if (yydebug)
7022         {
7023         ...
7024         }
7025         #endif
7026
7027         into
7028
7029         if (yydebug)
7030         {
7031         ...
7032         }
7033
7034         unfortunately this leads to a CPP conflict when
7035         `--name-prefix=foo' is used since it produces `#define yydebug
7036         foodebug'.
7037
7038         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7039         (YYDPRINTF): New macro.
7040         Spread its use.
7041         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7042         the bison options.
7043         Also test `--verbose', `--defines' and `--name-prefix'.
7044
7045 2000-10-02  Akim Demaille  <akim@epita.fr>
7046
7047         Improve the readability of the produced parsers.
7048
7049         * src/bison.s1: Formatting changes.
7050         Improve the comment related to the `$' mark.
7051         (yydefault): Don't fall through to `yyresume': `goto' there.
7052         * src/output.c (output_parser): When the `$' is met, skip the end
7053         of its line.
7054         New variable, `number_of_dollar_signs', to check there's exactly
7055         one `$' in the parser skeleton.
7056
7057 2000-10-02  Akim Demaille  <akim@epita.fr>
7058
7059         * lib/xstrdup.c: New file, from the fileutils.
7060         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7061         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7062         instead of strlen + xmalloc + strcpy.
7063         * src/symtab.c (copys): Remove, use xstrdup instead.
7064
7065 2000-10-02  Akim Demaille  <akim@epita.fr>
7066
7067         * src/gram.h (associativity): New enum type which replaces the
7068         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7069         `right_assoc', `left_assoc' and `non_assoc'.
7070         Adjust all dependencies.
7071         * src/reader.c: Formatting changes.
7072         (LTYPESTR): Don't define it, use it as a literal in
7073         `reader_output_yylsp'.
7074         * src/symtab.h (symbol_class): New enum type which replaces the
7075         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7076         `sunknown', `stoken and `snterm'.
7077
7078 2000-10-02  Akim Demaille  <akim@epita.fr>
7079
7080         * src/getargs.c (fixed_outfiles): Rename as...
7081         (yaccflag): for consistency and accuracy.
7082         Adjust dependencies.
7083
7084 2000-10-02  Akim Demaille  <akim@epita.fr>
7085
7086         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7087         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
7088         difficult and introduced a lot of core dump.  It turns out that
7089         Bison used an implementation of `xmalloc' based on `calloc', and
7090         at various places it does depend upon the initialization to 0.  I
7091         have not tried to isolate the pertinent places, and all the former
7092         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
7093         someone should address this issue.
7094
7095         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7096         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7097         files.
7098         Adjust dependencies.
7099         * src/warshall.h: New file.
7100         Propagate.
7101
7102 2000-10-02  Akim Demaille  <akim@epita.fr>
7103
7104         Various anti-`extern in *.c' changes.
7105
7106         * src/system.h: Include `assert.h'.
7107
7108 2000-10-02  Akim Demaille  <akim@epita.fr>
7109
7110         * src/state.h (nstates, final_state, first_state, first_shift)
7111         (first_reduction): Move their exportation from here...
7112         * src/LR0.h: to here.
7113         Adjust dependencies.
7114         * src/getargs.c (statisticsflag): New variable.

7167
7168         * src/reader.h: New file.

7183
7184         * src/lalr.h: New file.

7187
7188 2000-10-02  Akim Demaille  <akim@epita.fr>
7189
7190         * src/output.c (token_actions): Introduce a temporary array,
7191         YYDEFACT, that makes it possible for this function to use
7192         output_short_table.
7193
7194 2000-10-02  Akim Demaille  <akim@epita.fr>
7195
7196         `user_toknums' is output as a `short[]' in `output.c', while it is
7197         defined as a `int[]' in `reader.c'.  For consistency with the
7198         other output tables, `user_toknums' is now defined as a table of
7199         shorts.
7200
7201         * src/reader.c (user_toknums): Be a short table instead of an int
7202         table.

7212
7213         * src/output.c (output): Topological sort of the functions, in
7214         order to get rid of the `static' prototypes.
7215         No longer use `register'.
7216         * src/output.h: New file.
7217         Propagate its inclusion in files explicitly prototyping functions
7218         from output.c.

7227         * src/closure.c: Formatting changes, topological sort over the
7228         functions, use of closure.h.
7229         (initialize_closure, finalize_closure):  Rename as...
7230         (new_closure, free_closure): these.  Adjust dependencies.

7240         inclusion.
7241         Don't define PARAMS.
7242         * src/system.h: Define PARAMS.
7243         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7244         purpose of config.h.  system.h must not try to fix wrong
7245         definitions in config.h.

7285
7286         * configure.in: Append WARNING_CFLAGS to CFLAGS.

7289
7290 2000-09-18  Akim Demaille  <akim@epita.fr>

7407         the file name, not the whole `#line LINE FILE'.
7408
7409 2000-03-17  Akim Demaille  <akim@epita.fr>
7410
7411         On syntax errors, report the token on which we choked.
7412
7413         * src/bison.s1 (yyparse): In the label yyerrlab, when

7433         copy_comment.  Removed now unused `match', `ended',
7434         `cplus_comment'.
7435         (copy_comment, copy_string): Moved, to be visible from
7436         copy_definition.

7439

7462
7463         Change the handling of @s so that they behave exactly like $s.
7464         There is now a pseudo variable @$ (readble and writable), location
7465         of the lhs of the rule (by default ranging from the location of
7466         the first symbol of the rhs, to the location of the last symbol,
7467         or, if the rhs is empty, YYLLOC).
7468
7469         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7470         yyval.
7471         (yyparse): When providing a default semantic action, provide a
7472         default location action.
7473         (after the $): No longer change `*YYLSP', just stack YYLOC the
7474         same way you stack YYVAL.
7475         * src/reader.c (read_declarations): Use warns.
7476         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7477         (copy_action, case '@'): Likewise.
7478         Use a standard error message, to save useless work from
7479         translators.
7480
7481 2000-03-17  Akim Demaille  <akim@epita.fr>
7482

7500
7501         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7502         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7503         One `#if YYDEBUG' remains, since it uses variables which are
7504         defined only if `YYDEBUG != 0'.
7505
7506 2000-03-16  Akim Demaille  <akim@epita.fr>

7530         handled via src/Makefile.am.

7532         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

7538         the proper line number and file name.
7539         (DEFS): Propagate the location of bison library files and of the
7540         locale files.
7541         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7542         builddir.
7543         * acinclude.m4: Remove, replaced by the directory m4.
7544         * m4/Makefile.am (EXTRA_DIST): New variable.
7545         * m4/gettext.m4: New file, from the fileutils.
