ChangeLog

   1 2002-10-16  Paul Eggert  <eggert@twinsun.com>
   2
   3         * NEWS: Officially drop support for building Bison with K&R C,
   4         since it didn't work anyway and it's not worth worrying about.
   5         * Makefile.maint (wget_files): Remove ansi2knr.c.
   6         (ansi2knr.c-url_prefix): Remove.
   7         * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
   8         * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
   9         * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
  10
  11 2002-10-15  Paul Eggert  <eggert@twinsun.com>
  12
  13         Stop using the "enum_" trick for K&R-style function definitions;
  14         it confused me, and I was the author!  Instead, assume that people
  15         who want to use K&R C compilers (when using these modules in GCC,
  16         perhaps?) will run ansi2knr.
  17
  18         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
  19         All uses of "enum_" changed to "enum ".
  20         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
  21         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
  22
  23         * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,
  24         abitset_and_or_cmp, abitset_andn, abitset_andn_cmp,
  25         abitset_andn_or, abitset_andn_or_cmp, abitset_bytes, abitset_copy,

  30         abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
  31         abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
  32         Use function prototypes; this removes the need for declaring
  33         static functions simply to provide their prototypes.
  34         * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,
  35         bitset_andn_or_, bitset_andn_or_cmp_, bitset_bytes, bitset_copy_,

  39         bitset_op4_cmp, bitset_or_and_, bitset_or_and_cmp_, bitset_prev,
  40         bitset_print, bitset_release_memory, bitset_toggle_,
  41         bitset_type_choose, bitset_type_get, bitset_type_name_get,
  42         debug_bitset): Likewise.
  43         * lib/bitset.h (bitset_set, bitset_reset, bitset_test): Likewise.
  44         * lib/bitset_stats.c (bitset_log_histogram_print,

  61         bitsetv_zero, bitsetv_ones, bitsetv_transitive_closure,
  62         bitsetv_dump, debug_bitsetv): Likewise.

  88
  89         Version 1.75.
  90
  91 2002-10-14  Akim Demaille  <akim@epita.fr>
  92
  93         * tests/Makefile.am (maintainer-check-posix): New.
  94
  95 2002-10-14  Akim Demaille  <akim@epita.fr>
  96
  97         * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
  98         member.
  99
 100 2002-10-14  Akim Demaille  <akim@epita.fr>
 101
 102         * src/tables.c (table_ninf_remap): base -> tab.
 103         Reported by Matt Rosing.
 104
 105 2002-10-14  Paul Eggert  <eggert@twinsun.com>
 106
 107         * tests/action.at, tests/calc.at, tests/conflicts.at,
 108         tests/cxx-type.at, tests/headers.at, tests/input.at,
 109         tests/regression.at, tests/synclines.at, tests/torture.at:
 110         Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
 111         so that the tests still work even if POSIXLY_CORRECT is set.
 112         * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
 113
 114         * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
 115         for portability to K&R hosts.  Fix typo: signed char is guaranteed
 116         only to 127, not to 128.
 117         * data/glr.c (yysigned_char): New type.
 118         * data/yacc.c (yysigned_char): Likewise.
 119         * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
 120
 121 2002-10-13  Paul Eggert  <eggert@twinsun.com>
 122
 123         * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
 124         true due to limited range of data type" warning from GCC.
 125
 126         * data/c.m4 (b4_token_defines): Protect against double-inclusion
 127         by wrapping enum yytokentype's definition inside #ifndef
 128         YYTOKENTYPE.  This undoes a bug I introduced on 2002-10-12.
 129
 130 2002-10-13  Akim Demaille  <akim@epita.fr>
 131
 132         * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
 133         Un yy- yyrhs to avoid the name clash with the global YYRHS.
 134
 135 2002-10-13  Akim Demaille  <akim@epita.fr>
 136
 137         * Makefile.maint: Update from Autoconf 2.54.
 138         * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
 139
 140 2002-10-13  Akim Demaille  <akim@epita.fr>
 141
 142         * src/print.c (print_state): Separate the list of solved conflicts
 143         from the other items.
 144         * tests/conflicts.at (Resolved SR Conflicts): Adjust.
 145
 146 2002-10-13  Akim Demaille  <akim@epita.fr>
 147
 148         Let nondeterministic skeletons be usable with deterministic
 149         tables.
 150
 151         With the patch, GAWK compiled by GCC without -O2 passes its test
 152         suite using a GLR parser driven by LALR tables.  It fails with -O2
 153         because `struct stat' gives two different answers on my machine:
 154         88 (definition of an auto var) and later 96 (memset on this var).
 155         Hence the stack is badly corrumpted.  The headers inclusion is to
 156         blame: if I move the awk.h inclusion before GLR's system header
 157         inclusion, the two struct stat have the same size.
 158
 159         * src/tables.c (pack_table): Always create conflict_table.
 160         (token_actions): Always create conflict_list.
 161         * data/glr.c (YYFLAG): Remove, unused.
 162
 163 2002-10-13  Akim Demaille  <akim@epita.fr>
 164
 165         * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
 166         (O0FLAGS): New.
 167         (VALGRIND, GXX): New.
 168         * tests/atlocal.in (CFLAGS): Use O0FLAGS.
 169         * tests/bison.in: Run $PREBISON a pre-command.
 170         * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
 171         (maintainer-check-g++): New.
 172         * Makefile.am (maintainer-check): New.
 173
 174 2002-10-13  Akim Demaille  <akim@epita.fr>
 175
 176         * data/glr.c: Formatting changes.
 177         Tweak some trace messages to match yacc.c's.
 178
 179 2002-10-13  Akim Demaille  <akim@epita.fr>
 180
 181         GLR parsers sometimes raise parse errors instead of performing the
 182         default reduction.
 183         Reported by Charles-Henry de Boysson.
 184
 185         * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
 186         check the length of the traces when %glr.
 187         (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
 188         GLR's traces.
 189         (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
 190         Test GLR parsers.
 191         * data/glr.c (YYLEFTMOST_STATE): Fix its value.
 192         (yyltype): Remove the yy prefix from the member names.
 193         (yytable): Complete its comment.
 194         (yygetLRActions): Map error action number from YYTABLE from
 195         YYTABLE_NINF to 0.
 196         (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
 197         (which was a bug: it should have been YYTABEL_NINF, and yet it was
 198         not satisfying as we could compare an YYACTION computed from
 199         YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
 200         only value for error actions.
 201         (yyreportParseError): In verbose parse error messages, don't issue
 202         `error' in the list of expected tokens.
 203         * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
 204         next action to perform to match glr.c's decoding.
 205         (yytable): Complete its comment.
 206
 207 2002-10-13  Paul Eggert  <eggert@twinsun.com>
 208
 209         Fix problem reported by Henrik Grubbstroem in
 210         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
 211         "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
 212         because the Bison parser reads the second action before reducing
 213         the first one.
 214         * src/scan-gram.l (rule_length): New static var.
 215         Use it to keep track of the rule length in the scanner, since
 216         we can't expect the parser to be in lock-step sync with the scanner.
 217         (handle_action_dollar, handle_action_at): Use this var.
 218         * tests/actions.at (Exotic Dollars): Test for the problem.
 219
 220 2002-10-12  Paul Eggert  <eggert@twinsun.com>
 221
 222         * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
 223         * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
 224         Include <sys/time.h> when checking for clock_t and struct tms.
 225         Use same include order as source.
 226         This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
 227         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
 228
 229         * lib/timevar.c: Update copyright date and clarify comments.
 230         (get_time) [IN_GCC]: Keep the GCC version for reference.
 231
 232         * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
 233         GCC version as of today, then merge Bison's changes.
 234         Change "GCC" to "Bison" in copyright notice.  timevar.def's
 235         author is Akim, so change that too.
 236
 237         * src/reader.c (grammar_current_rule_check):
 238         Don't worry about the default action if $$ is untyped.
 239         Prevents bogus warnings reported by Jim Gifford in
 240         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
 241
 242         * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
 243         * data/glr.c, data/lalr1.cc, data/yacc.c:
 244         Output token definitions before the first part of user declarations.
 245         Fixes compatibility problem reported by Jim Gifford for kbd in
 246         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
 247
 248 2002-10-11  Paul Eggert  <eggert@twinsun.com>
 249
 250         * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
 251         (yyparse): here.  This undoes some of the 2002-07-25 change.
 252         Compatibility problem reported by Ralf S. Engelschall with
 253         OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
 254
 255 2002-10-11  Akim Demaille  <akim@epita.fr>
 256
 257         * tests/regression.at Characters Escapes): New.
 258         * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
 259         characters.
 260         Reported by Jan Nieuwenhuizen.
 261
 262 2002-10-11  Akim Demaille  <akim@epita.fr>
 263
 264         * po/id.po: New.
 265
 266 2002-10-10  Paul Eggert  <eggert@twinsun.com>
 267
 268         Portability fixes for bitsets; this also avoids several GCC
 269         warnings.
 270
 271         * lib/abitset.c: Include <stddef.h>, for offsetof.
 272         * lib/lbitset.c: Likewise.
 273
 274         * lib/abitset.c (abitset_bytes): Return a size that is aligned
 275         properly for vectors of objects.  Do not assume that adding a
 276         header size to a multiple of a word size yields a value that is
 277         properly aligned for the whole union.
 278         * lib/bitsetv.c (bitsetv_alloc): Likewise.
 279
 280         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
 281         unique names for structures.
 282         * lib/ebitset.c (ebitset_bytes): Likewise.
 283         * lib/lbitset.c (lbitset_bytes): Likewise.

 287         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

 291         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
 292         to improve the type-checking that GCC can do.
 293         * lib/bitset.c (bitset_op4_cmp): Likewise.
 294         * lib/bitset_stats.c (bitset_stats_count,
 295         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
 296         bitset_stats_copy, bitset_stats_disjoint_p,

 307         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
 308
 309         * lib/abitset.h: Include bitset.h, not bbitset.h.

 311         * lib/lbitset.h: Likewise.
 312
 313         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
 314         All instances of parameters of type enum bitset_opts are now of
 315         type enum_bitset_opts, to conform to the C Standard, and similarly
 316         for enum_bitset_type.
 317         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
 318         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
 319
 320         Do not use "struct bitset_struct" to mean different things in
 321         different modules.  Not only is this confusing, it violates
 322         the C Standard, which requires that structure types in different
 323         modules must be compatible if one is to be passed to the other.
 324         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
 325         All instances of "struct bitset_struct *" replaced with "bitset".
 326         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
 327         (union bitset_union, struct abitset_struct, struct ebitset_struct,
 328         struct lbitset_struct, struct bitset_stats_struct): New types.
 329         All uses of struct bitset_struct changed to union bitset_union,
 330         etc.
 331         * lib/abitset.c (struct abitset_struct, abitset,
 332         struct bitset_struct): Remove.
 333         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
 334         struct bitset_struct): Remove.
 335         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
 336         bitset_struct): Remove.
 337         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
 338         Likewise.
 339
 340         Do not call a function of type T using a call that assumes the
 341         function is of a different type U.  Standard C requires that a
 342         function must be called with a type that is compatible with its
 343         definition.
 344         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 345         New decls.

 351         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
 352         decls.
 353         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
 354         (ebitset_vtable): Use them.
 355         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,

 358
 359         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
 360         Declare.
 361
 362         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
 363         GCC warning.
 364         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
 365         Use offsetof, for simplicity.

 367 2002-10-06  Paul Eggert  <eggert@twinsun.com>
 368
 369         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
 370         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
 371         <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
 372         which was inadvertently undone by the 2002-09-30 patch.
 373         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
 374         the same width as int.

 385         signifies end-of-input.  Warn about negative chars.  Mention
 386         the portable Standard C character set.
 387
 388         The GNU coding standard says CFLAGS and YFLAGS are reserved
 389         for the installer to set.

 397         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
 398         * src/reader.c (reader): Use it.
 399
 400         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
 401         POSIX 1003.1-2001 has removed fgrep.

 634         as int, and similarly for yyposn and YYINDEX.
 635
 636         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 637
 638         * lib/Makefile.am (INCLUDES): Do not include from the intl
 639         directory, which has been removed.
 640         * src/Makefile.am (INCLUDES): Likewise.

 659
 660         * lib/abitset.c (abitset_op1): Use -1, not ~0, as memset arg (for
 661         portability to one's complement hosts!).
 662         * lib/ebitset.c (ebitset_op1): Likewise.
 663         * lib/lbitset.c (lbitset_op1): Likewise.
 664

 674
 675         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 676         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 677         check for void *.
 678
 679         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 680         size_t; the old version tried to do this but casted improperly.
 681         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 682         (bitset_test): Now returns int, not unsigned long.

 685         (_): New macro.
 686         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 687         name locals "index", as it generates unnecessary warnings on some
 688         hosts that have an "index" function.
 689
 690         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 691         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
 692         they need translation.

 712         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 713         lib/timevar.c.
 714         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 715         manual recommends.
 716         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 717
 718         * src/complain.c (strerror_r): Remove decl; not needed.
 719         (strerror): Use same pattern as ../lib/error.c.

 724
 725         * src/main.c (main): Cast result of bindtextdomain and textdomain
 726         to void, to avoid a GCC warning when --disable-nls is in effect.
 727
 728         * src/scan-gram.l: Use strings rather than escapes when possible,
 729         to minimize the number of warnings from xgettext.
 730         (handle_action_dollar, handle_action_at): Don't use isdigit,
 731         as it mishandles negative chars and it may not work as expected
 732         outside the C locale.
 733
 734         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 735         this is a GCC extension and is not portable to other compilers.
 736
 737         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 738         Do not include <ctype.h>; no longer needed.
 739         Do not include <malloc.h>; no longer needed (and generates
 740         warnings on OpenBSD 3.0).
 741
 742         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
 743         it's not portable.
 744
 745         * tests/regression.at: Do not use 'cc -c input.c -o input';
 746         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
 747
 748         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
 749         exit status as failure, not just exit status 1.  Sun C exits
 750         with status 2 sometimes.
 751
 752         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
 753         Use it for the two large tests.

 756
 757         * src/conflicts.c (conflicts_output): Don't output rules never
 758         reduced here, since anyway that computation doesn't work.

 767         (token_actions): here.
 768         * src/main.c (main): Make the parser before making the report, so
 769         that rules never reduced are computed.
 770         Call grammar_rules_never_reduced_report.
 771         * src/print.c (print_results): Report rules never reduced.
 772         * tests/conflicts.at, tests/reduce.at: Adjust.
 773
 774 2002-08-01  Akim Demaille  <akim@epita.fr>
 775
 776         Instead of attaching lookaheads and duplicating the rules being
 777         reduced by a state, attach the lookaheads to the reductions.
 778
 779         * src/state.h (state_t): Remove the `lookaheads',
 780         `lookaheads_rule' member.
 781         (reductions_t): Add a `lookaheads' member.

 784         to 0.

 790         (add_lookback_edge): Adjust.
 791         (state_lookaheads_count): New.
 792         (states_lookaheads_initialize): Merge into...
 793         (initialize_LA): this.
 794         (lalr_free): Adjust.
 795         * src/main.c (main): Don't free nullable and derives too early: it
 796         is used by --verbose.
 797         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
 798
 799 2002-08-01  Akim Demaille  <akim@epita.fr>
 800
 801         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of

 803         (set_derives, free_derives): Rename as...

 810         pointers, instead of their numbers.
 811         * src/main.c (main): Call nullable_free, and derives_free earlier,
 812         as they were lo longer used.
 813
 814 2002-08-01  Akim Demaille  <akim@epita.fr>
 815
 816         * lib/timevar.c (get_time): Include children time.

 818         state_t.
 819         * src/lalr.c (LA, LArule): Static.

 824         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
 825         (tables_generate): do it, since that's also it which allocates
 826         them.
 827         Don't free LA and LArule, main does.
 828
 829 2002-07-31  Akim Demaille  <akim@epita.fr>

 834         (conflict_list, conflict_list_cnt, table, check, table_ninf)
 835         (yydefgoto, yydefact, high): Move to...

 858
 859         * lib/timevar.c, lib/timevar.h, lib/timevar.def: New,
 860         stolen/adjusted from GCC.
 861         * m4/stage.m4: Remove time related checks.

 875         * src/getargs.h (enum trace_e): New.
 876         * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
 877         (long_options, short_options): --trace/-T takes an optional
 878         argument.
 879         Change all the uses of trace_flag to reflect the new flags.
 880         * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
 881
 882         Strengthen `stage' portability.
 883
 884         * m4/stage.m4 (BISON_PREREQ_STAGE): New.
 885         * configure.in: Use it.
 886         Don't check for malloc.h and sys/times.h.
 887         * src/system.h: Include them when appropriate.
 888         * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
 889         times and struct tms are available.
 890
 891 2002-07-30  Akim Demaille  <akim@epita.fr>
 892
 893         In verbose parse error message, don't report `error' as an
 894         expected token.
 895         * tests/actions.at (Printers and Destructors): Adjust.
 896         * tests/calc.at (Calculator $1): Adjust.
 897         * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
 898         error message, do not report the parser accepts the error token in
 899         that state.
 900
 901 2002-07-30  Akim Demaille  <akim@epita.fr>

 911 2002-07-30  Akim Demaille  <akim@epita.fr>
 912
 913         Report rules which are never reduced by the parser: those hidden
 914         by conflicts.
 915
 916         * src/LR0.c (save_reductions): Don't make the final state too
 917         different: save its reduction (accept) instead of having a state
 918         without any action (no shift or goto, no reduce).
 919         Note: the final state is now a ``regular'' state, i.e., the
 920         parsers now contain `reduce 0' as default reduction.
 921         Nevertheless, since they decide to `accept' when yystate =
 922         final_state, they still will not reduce rule 0.
 923         * src/print.c (print_actions, print_reduction): Adjust.
 924         * src/output.c (action_row): Track reduced rules.
 925         (token_actions): Report rules never reduced.
 926         * tests/conflicts.at, tests/regression.at: Adjust.
 927
 928 2002-07-30  Akim Demaille  <akim@epita.fr>
 929
 930         `stage' was accidently included in a previous patch.
 931         Initiate its autoconfiscation.
 932
 933         * configure.in: Look for malloc.h and sys/times.h.
 934         * src/main.c (stage): Adjust.
 935         Report only when trace_flag.
 936
 937 2002-07-29  Akim Demaille  <akim@epita.fr>
 938
 939         * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not

 946
 947 2002-07-29  Akim Demaille  <akim@epita.fr>
 948
 949         Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $.
 950
 951         * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
 952         (endtoken, accept): these.
 953         * src/reader.c (reader): Set endtoken's default tag to "$end".
 954         Set undeftoken's tag to "$undefined" instead of "$undefined.".
 955         * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
 956         Adjust.
 957
 958 2002-07-29  Akim Demaille  <akim@epita.fr>
 959
 960         * src/reduce.c (reduce_grammar): When the language is empty,
 961         complain about the start symbol, not the axiom.

2016         * src/parse-gram.y: Use it.
2017
2018         * data/bison.simple, data/bison.c++: b4_stype is now either not
2019         defined, then default to int, or to the contents of %union,
2020         without `union' itself.
2021         Adjust.
2022         * src/muscle_tab.c (muscle_init): Don't predefine `stype'.
2023
2024         * src/output.c (actions_output): Don't output braces, as they are

2031         that the epilogue has a proper #line.
2032

2038         * tests/calc.at: Do not use `%token "foo"' as it makes not sense

2042
2043         * src/scan-gram.l: Working properly with escapes in user

2047         (AT_DATA_HORIZONTAL_GRAMMAR): Respect the `%token ID NUM STRING'
2048         grammar.
2049         Use more modest sizes, as for the time being the parser does not
2050         release memory, and therefore the process swallows a huge amount
2051         of memory.
2052
2053         * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the
2054         stricter %token grammar.
2055

2059
2060         * tests/regression.at (Invalid %directive): Remove, as it is now
2061         meaningless.
2062         (Invalid inputs): Adjust to the new error messages.
2063         (Token definitions): The new grammar doesn't allow too many
2064         eccentricities.
2065
2066         * src/lex.h, src/lex.c: Remove.
2067         * src/reader.c (lastprec, skip_to_char, read_signed_integer)

2075
2076         * src/reader.c  (parse_action): Don't store directly into the
2077         rule's action member: return the action as a string.
2078         Don't require `rule_length' as an argument: compute it.

2125         use it in...

2139
2140         Remove `%thong' support as it is undocumented, unused, duplicates
2141         `%token's job, and creates useless e-mail traffic with people who
2142         want to know what it is, why it is undocumented, unused, and
2143         duplicates `%token's job.
2144

2213
2214         * src/output.c (output_skeleton): Put an explicit path in front of
2215         the skeleton file name, rather than relying on the -I directory,

2289
2290         * data/bison.simple (yyparse): Correct error handling to conform to

2297 2002-05-20  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
2298
2299         * data/bison.simple (yyr1): Don't use yy_token_number_type as element
2300         type; it isn't always big enough, since it doesn't necessarily
2301         include non-terminals.
2302         (yytranslate): Expand definition of yy_token_number_type, so that
2303         the latter can be removed.

2305         * data/bison.c++ (r1_): Parallel change to yyr1 in bison.simple---
2306         don't use TokenNumberType as element type.

2520         Note: this patch partially drops `semantic-parser' support: it
2521         always does `rule_length - n', where semantic parsers ought to
2522         always use `-n'.

2657 2002-04-19  Akim Demaille  <akim@epita.fr>
2658
2659         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
2660         as Lex/Flex'.
2661         (Debugging): More details about enabling the debugging features.
2662         (Table of Symbols): Describe $$, $n, @$, and @n.
2663         Suggested by Tim Josling.
2664
2665 2002-04-19  Akim Demaille  <akim@epita.fr>
2666
2667         * doc/bison.texinfo: Remove the uses of the obsolete @refill.
2668
2669 2002-04-10  Akim Demaille  <akim@epita.fr>
2670
2671         * src/system.h: Rely on HAVE_LIMITS_H.
2672         Suggested by Paul Eggert.
2673
2674 2002-04-09  Akim Demaille  <akim@epita.fr>
2675
2676         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2677         full stderr, and strip it according to the bison options, instead
2678         of composing the error message from different bits.
2679         This makes it easier to check for several error messages.
2680         Adjust all the invocations.
2681         Add an invocation exercising the error token.
2682         Add an invocation demonstrating a stupid error message.
2683         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
2684         Adjust the tests.
2685         Error message are for stderr, not stdout.
2686
2687 2002-04-09  Akim Demaille  <akim@epita.fr>
2688
2689         * src/gram.h, src/gram.c (error_token_number): Remove, use
2690         errtoken->number.
2691         * src/reader.c (reader): Don't specify the user token number (2)
2692         for $undefined, as it uselessly prevents using it.
2693         * src/gram.h (token_number_t): Move to...
2694         * src/symtab.h: here.
2695         (state_t.number): Is a token_number_t.
2696         * src/print.c, src/reader.c: Use undeftoken->number instead of
2697         hard coded 2.
2698         (Even though this 2 is not the same as above: the number of the
2699         undeftoken remains being 2, it is its user token number which
2700         might not be 2).
2701         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2702         `user_token_number_max'.
2703         Output `undef_token_number'.
2704         * data/bison.simple, data/bison.c++: Use them.
2705         Be sure to map invalid yylex return values to
2706         `undef_token_number'.  This saves us from gratuitous SEGV.
2707
2708         * tests/conflicts.at (Solved SR Conflicts)
2709         (Unresolved SR Conflicts): Adjust.
2710         * tests/regression.at (Web2c Actions): Adjust.
2711
2712 2002-04-08  Akim Demaille  <akim@epita.fr>
2713
2714         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
2715         Adding #line.
2716         Remove the duplicate `typedefs'.
2717         (RhsNumberType): Fix the declaration and various other typos.
2718         Use __ofile__.
2719         * data/bison.simple: Use __ofile__.
2720         * src/scan-skel.l: Handle __ofile__.
2721
2722 2002-04-08  Akim Demaille  <akim@epita.fr>
2723
2724         * src/gram.h (item_number_t): New, the type of item numbers in
2725         RITEM.  Note that it must be able to code symbol numbers as
2726         positive number, and the negation of rule numbers as negative
2727         numbers.
2728         Adjust all dependencies (pretty many).
2729         * src/reduce.c (rule): Remove this `short *' pointer: use
2730         item_number_t.
2731         * src/system.h (MINSHORT, MAXSHORT): Remove.
2732         Include `limits.h'.
2733         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2734         (shortcpy): Remove.
2735         (MAXTABLE): Move to...
2736         * src/output.c (MAXTABLE): here.
2737         (prepare_rules): Use output_int_table to output rhs.
2738         * data/bison.simple, data/bison.c++: Adjust.
2739         * tests/torture.at (Big triangle): Move the limit from 254 to
2740         500.
2741         * tests/regression.at (Web2c Actions): Ajust.
2742
2743         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2744         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2745         passes, but produces negative #line number, once fixed, GCC is
2746         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2747         C), it passes.
2748         * src/state.h (state_h): Code input lines on ints, not shorts.
2749
2750 2002-04-08  Akim Demaille  <akim@epita.fr>
2751
2752         * src/reduce.c (reduce_grammar): First reduce the nonterminals,
2753         and then the grammar.
2754
2755 2002-04-08  Akim Demaille  <akim@epita.fr>
2756
2757         * src/system.h: No longer using strndup.

2762         * src/output.c (output_table_data): Return the longest number.
2763         (prepare_tokens): Output `token_number_max').
2764         * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
2765         New.
2766         Use them to define yy_token_number_type/TokenNumberType.
2767         Use this type for yytranslate.
2768         * tests/torture.at (Big triangle): Push the limit from 124 to
2769         253.

2779
2780         * src/gram.h, src/gram.c (nitems): Remove, it is an alias of
2781         nritems.
2782         Adjust dependencies.
2783

2816         * src/reader.c (bucket_check_defined, bucket_make_alias)

2840 2002-04-07  Akim Demaille  <akim@epita.fr>
2841
2842         * src/gram.h (rule_s): prec and precsym are now pointers
2843         to the bucket giving the priority/associativity.
2844         Member `associativity' removed: useless.
2845         * src/reduce.c, src/conflicts.c: Adjust.
2846

2873
2874         * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
2875
2876 2002-04-07  Akim Demaille  <akim@epita.fr>
2877
2878         Be sure never to walk through RITEMS, but use only data related to
2879         the rules themselves. RITEMS should be banished.
2880
2881         * src/output.c (output_token_translations): Rename as...
2882         (prepare_tokens): this.
2883         In addition to `translate', prepare the muscles `tname' and
2884         `toknum', which were handled by...
2885         (output_rule_data): this.
2886         Remove, and move the remainder of its outputs into...
2887         (prepare_rules): this new routines, which also merges content from

2896
2897         * src/LR0.c (new_state): Display `nstates' as the name of the
2898         newly created state.
2899         Adjust to initialize first_state and last_state if needed.
2900         Be sure to distinguish the initial from the final state.
2901         (new_states): Create the itemset of the initial state, and use
2902         new_state.
2903         * src/closure.c (closure): Now that the initial state has its
2904         items properly set, there is no need for a special case when
2905         creating `ruleset'.
2906
2907         As a result, now the rule 0, reducing to $axiom, is visible in the
2908         outputs.  Adjust the test suite.
2909
2910         * tests/conflicts.at (Solved SR Conflicts)
2911         (Unresolved SR Conflicts): Adjust.

2919         * src/output.c (output_gram): Likewise.
2920
2921 2002-04-07  Akim Demaille  <akim@epita.fr>
2922
2923         * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's
2924         bucket.
2925         Adjust all dependencies.
2926         * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
2927         `number' of the buckets too.
2928         * src/gram.h: Include `symtab.h'.
2929         (associativity): Move to...
2930         * src/symtab.h: here.
2931         No longer include `gram.h'.
2932

2940         the end of `rules', and count them out of `nrules'.
2941         (reduce_output, dump_grammar): Adjust.
2942         * src/print.c (print_grammar): It is no longer needed to check for
2943         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
2944         * tests/reduce.at (Reduced Automaton): New test.
2945
2946 2002-04-07  Akim Demaille  <akim@epita.fr>
2947
2948         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
2949         lacking `+ 1' to nrules, Bison reported as useless a token if it
2950         was used solely to set the precedence of the last rule...
2951
2952 2002-04-07  Akim Demaille  <akim@epita.fr>
2953
2954         * data/bison.c++, data/bison.simple: Don't output the current file
2955         name in #line, to avoid useless diffs between two identical
2956         outputs under different names.
2957
2958 2002-04-07  Akim Demaille  <akim@epita.fr>
2959
2960         * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
2961         Normalize loops to using `< nrules + 1', not `<= nrules'.
2962
2963 2002-04-07  Akim Demaille  <akim@epita.fr>
2964
2965         * TODO: Update.
2966
2967 2002-04-07  Akim Demaille  <akim@epita.fr>
2968
2969         * src/output.c, src/reader.c, src/symtab.c, src/symtab.h: Rename
2970         bucket.value as bucket.number.
2971
2972 2002-04-07  Akim Demaille  <akim@epita.fr>

2976         * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
2977         RHS, instead of being an index in RITEMS.
2978
2979 2002-04-04  Paul Eggert  <eggert@twinsun.com>
2980
2981         * doc/bison.texinfo: Update copyright date.
2982         (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.
2983         (Symbols): Warn about running Bison in one character set,
2984         but compiling and/or running in an incompatible one.
2985         Warn about character code 256, too.
2986
2987 2002-04-03  Paul Eggert  <eggert@twinsun.com>
2988
2989         * src/bison.data (YYSTACK_ALLOC): Depend on whether
2990         YYERROR_VERBOSE is nonzero, not whether it is defined.
2991
2992         Merge changes from bison-1_29-branch.
2993
2994 2002-03-20  Paul Eggert  <eggert@twinsun.com>

3249         causing more problems than it was curing, since it didn't work
3250         properly on some nonstandard C++ compilers.  This can wait

3355         (token_definitions_output): Adjust prototypes.
3356         * src/scan-skel.l: Instead of scanning the skeletons, it now
3357         processes the output of m4: `__oline__' and `#output'.
3358         * data/bison.simple: Adjust to be used by M4(sugar).
3359         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
3360         to date.
3361         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3362         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
3363         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
3364         shamelessly stolen from CVS Autoconf.
3365
3366 2002-02-05  Akim Demaille  <akim@epita.fr>
3367
3368         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
3369         * configure.in: Check for the declarations of free and malloc.
3370         * src/muscle_tab.c: Adjust.
3371
3372 2002-02-05  Akim Demaille  <akim@epita.fr>
3373
3374         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
3375         which have no values.
3376
3377 2002-02-05  Akim Demaille  <akim@epita.fr>
3378
3379         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
3380         * data/: here.
3381
3382 2002-01-29  Paul Eggert  <eggert@twinsun.com>
3383
3384         * src/bison.simple (YYSIZE_T): Do not define merely because
3385         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
3386         On some platforms, <alloca.h> does not declare YYSTD (size_t).
3387
3388 2002-01-27  Akim Demaille  <akim@epita.fr>
3389
3390         Fix `%nonassoc and eof'.
3391
3392         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
3393         which were not properly copied!  Replace
3394         memcpy (res->errs, src->errs, src->nerrs);
3395         with
3396         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
3397         !!!
3398         * tests/regression.at (%nonassoc and eof): Adjust to newest
3399         Autotest: `.' is not in the PATH.
3400
3401 2002-01-27  Akim Demaille  <akim@epita.fr>
3402
3403         * tests/sets.at (AT_EXTRACT_SETS): New.
3404         (Nullable): Use it.
3405         (Firsts): New.
3406
3407 2002-01-26  Akim Demaille  <akim@epita.fr>
3408
3409         * tests/actions.at, tests/calc.at, tests/headers.at,
3410         * tests/torture.at: Adjust to the newest Autotest which no longer
3411         forces `.' in the PATH.
3412
3413 2002-01-25  Akim Demaille  <akim@epita.fr>
3414
3415         * tests/regression.at (%nonassoc and eof): New.
3416         Suggested by Robert Anisko.

3420         Bison dumps core when trying to complain about broken input files.
3421         Reported by Cris van Pelt.
3422
3423         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
3424         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
3425         into...
3426         (Invalid inputs): Strengthen: exercise parse_percent_token.
3427
3428 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
3429
3430         * src/Makefile.am: Add bison.c++.
3431         * src/bison.c++: New skeleton.
3432
3433 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
3434
3435         * po/it.po: New.
3436
3437 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
3438
3439         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
3440
3441 2002-01-20  Marc Autret  <marc@gnu.org>
3442
3443         * src/files.c (compute_output_file_names): Fix
3444
3445 2002-01-20  Marc Autret  <marc@gnu.org>
3446
3447         * tests/output.at: New test.
3448         * src/files.c (compute_base_names): Don't map extensions when
3449         the YACC flag is set, use defaults.
3450         Reported by Evgeny Stambulchik.
3451
3452 2002-01-20  Marc Autret  <marc@gnu.org>
3453
3454         * src/system.h: Need to define __attribute__ away for non-GCC
3455         compilers as well (i.e. the vendor C compiler).
3456         Suggested by Albert Chin-A-Young.
3457
3458 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
3459
3460         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3461         canonical definition.
3462         * src/system.h: Use the canonical definition for PARAMS (avoids
3463         a conflict with the macro from lib/hash.h).
3464
3465 2002-01-11  Akim Demaille  <akim@epita.fr>
3466
3467         * configure.in: Use AC_FUNC_STRNLEN.
3468         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3469
3470 2002-01-09  Akim Demaille  <akim@epita.fr>
3471
3472         * src/files.c, src/files.h (output_infix): New.
3473         (tab_extension): Remove.
3474         (compute_base_names): Compute the former, drop the latter.
3475         * src/output.c (prepare): Insert the muscles `output-infix', and
3476         `output-suffix'.
3477         * src/parse-skel.y (string, string.1): New.
3478         (section.header): Use it.
3479         (section.yacc): Remove.
3480         (prefix): Remove too.
3481         * src/scan-skel.l: Adjust.
3482         * src/bison.simple, src/bison.hairy: Adjust.
3483
3484 2002-01-09  Akim Demaille  <akim@epita.fr>
3485
3486         * configure.in (WERROR_CFLAGS): Compute it.
3487         * src/Makefile.am (CFLAGS): Pass it.
3488         * tests/atlocal.in (CFLAGS): Idem.
3489         * src/files.c: Fix a few warnings.
3490         (get_extension_index): Remove, unused.
3491
3492 2002-01-08  Akim Demaille  <akim@epita.fr>
3493
3494         * src/getargs.c (AS_FILE_NAME): New.
3495         (getargs): Use it to convert DOSish file names.
3496         * src/files.c (base_name): Rename as full_base_name to avoid
3497         clashes with `base_name ()'.
3498         (filename_split): New.
3499         (compute_base_names): N-th rewrite, using filename_split.
3500
3501 2002-01-08  Akim Demaille  <akim@epita.fr>
3502
3503         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3504         New, stolen from the Fileutils 4.1.
3505         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3506         * configure.in: Check for the presence of memrchr, and of its
3507         prototype.
3508
3509 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3510
3511         * lib/hash.h (__P): Added definition for this macro.
3512         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3513         BUILT_SOURCES, to ensure they are generated first.
3514         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3515         %error-verbose to allow bootstrapping with bison 1.30x.
3516
3517 2002-01-06  Akim Demaille  <akim@epita.fr>
3518
3519         * src/reader.c (parse_braces): Don't fetch the next char, the
3520         convention is to fetch on entry.
3521         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3522         'switch' without a following semicolon.
3523         * tests/regression.at (braces parsing): New.
3524
3525 2002-01-06  Akim Demaille  <akim@epita.fr>
3526
3527         Bison is dead wrong in its RR conflict reports.
3528
3529         * tests/torture.at (GNU Cim Grammar): New.
3530         * src/conflicts.c (count_rr_conflicts): Fix.
3531
3532 2002-01-06  Akim Demaille  <akim@epita.fr>
3533
3534         Creating package.m4 from configure.ac causes too many problems.
3535
3536         * tests/Makefile.am (package.m4): Create it by hand,
3537         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3538
3539 2002-01-06  Akim Demaille  <akim@epita.fr>
3540
3541         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3542         skeleton.h.
3543
3544 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3545
3546         * doc/bison.texinfo (Debugging):
3547         Remove YYSTDERR; it's no longer defined or used.
3548         Also, s/cstdio.h/cstdio/.
3549
3550 2002-01-03  Akim Demaille  <akim@epita.fr>
3551
3552         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3553
3554 2002-01-03  Akim Demaille  <akim@epita.fr>
3555
3556         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3557         tracing code to --trace, wait for a better --trace option, with
3558         args.
3559
3560 2002-01-03  Akim Demaille  <akim@epita.fr>
3561
3562         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3563         The ISO C++ standard is extremely clear about it: stderr is
3564         considered a macro, not a regular symbol (see table 94 `Header
3565         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3566         Therefore std:: does not apply to it.  It still does with fprintf.
3567         Also, s/cstdio.h/cstdio/.
3568
3569 2002-01-03  Akim Demaille  <akim@epita.fr>
3570
3571         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3572         for non system headers.
3573
3574 2002-01-02  Akim Demaille  <akim@epita.fr>
3575
3576         Equip the skeleton chain with location tracking, runtime trace,
3577         pure parser and scanner.
3578
3579         * src/parse-skel.y: Request a pure parser, locations, and prefix
3580         renaming.
3581         (%union): Having several members with the same type does not help
3582         type mismatches, simplify.
3583         (YYPRINT, yyprint): New.
3584         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3585         (skel_error): this.
3586         Handle locations.
3587         * src/scan-skel.l: Adjust to these changes.
3588         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3589         (LOCATION_PRINT, skel_control_t): New.
3590
3591 2001-12-30  Akim Demaille  <akim@epita.fr>
3592
3593         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3594         replace `gb' with BLANKS.
3595         * src/scan-skel.l: Adjust.
3596
3597 2001-12-30  Akim Demaille  <akim@epita.fr>
3598
3599         * src/system.h: We don't need nor want bcopy.
3600         Throw away MS-DOS crap: we don't need getpid.
3601         * configure.in: We don't need strndup.  It was even causing
3602         problems: because Flex includes the headers *before* us,
3603         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3604         not visible.
3605         * lib/xstrndup.c: New.
3606         * src/scan-skel.l: Use it.
3607         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3608         * src/parse-skel.y: Use %directives instead of #defines.
3609
3610 2001-12-30  Akim Demaille  <akim@epita.fr>
3611
3612         * src/skeleton.h: New.
3613         * src/output.c (output_parser, output_master_parser): Remove, dead
3614         code.
3615         * src/output.h (get_lines_number, actions_output, guards_output)
3616         (token_definitions_output): Prototype them.
3617         * src/parse-skel.y: Add the license notice.
3618         Include output.h and skeleton.h.
3619         (process_skeleton): Returns void, and takes a single parameter.
3620         * src/scan-skel.l: Add the license notice.
3621         Include skeleton.h.
3622         Don't use %option yylineno: it seems that then Flex imagines
3623         REJECT has been used, and therefore it won't reallocate its
3624         buffers (which makes no other sense to me than a bug).  It results
3625         in warnings for `unused: yy_flex_realloc'.
3626
3627 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
3628
3629         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3630         (MUSCLE_INSERT_PREFIX): ...to there.
3631         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3632         (MUSCLE_INSERT_PREFIX): Move from here...
3633
3634         * src/bison.hairy: Add a section directive.  Put braces around muscle
3635         names.  This parser skeleton is still broken, but Bison should not
3636         choke on a bad muscle 'syntax'.
3637         * src/bison.simple: Add a section directive.  Put braces around muscle
3638         names.
3639
3640         * src/files.h (strsuffix, stringappend): Add declarations.
3641         (tab_extension): Add declaration.
3642         (short_base_name): Add declaration.
3643
3644         * src/files.c (strsuffix, stringappend): No longer static.  These
3645         functions are used in the skeleton parser.
3646         (tab_extension): New.
3647         (compute_base_names): Use the computations done in this function
3648         to guess if the generated parsers should have '.tab' in their
3649         names.
3650         (short_base_name): No longer static.
3651
3652         * src/output.c (output_skeleton): New.
3653         (output): Disable call to output_master_parser, and give a try to
3654         a new skeleton handling system.
3655         (guards_output, actions_output): No longer static.
3656         (token_definitions_output, get_lines_number): No longer static.
3657
3658         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3659
3660         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3661         parse-skel.y.
3662
3663         * src/parse-skel.y: New file.
3664         * src/scan-skel.l: New file.
3665
3666 2001-12-29  Akim Demaille  <akim@epita.fr>
3667
3668         %name-prefix is broken.
3669
3670         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3671         Adjust all dependencies.
3672         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3673         %name-prefix.
3674
3675         Renaming yylval but not yylloc is not consistent.  Now we do.
3676
3677         * src/bison.simple: Prefix yylloc if used.
3678         * doc/bison.texinfo (Decl Summary): Document that.
3679
3680 2001-12-29  Akim Demaille  <akim@epita.fr>
3681
3682         * doc/bison.texinfo: Promote `%long-directive' over
3683         `%long_directive'.
3684         Remove all references to fixed-output-files, yacc is enough.
3685
3686 2001-12-29  Akim Demaille  <akim@epita.fr>
3687
3688         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3689         user prologue.  These are defaults.
3690         * tests/actions.at (Mid-rule actions): Make sure the user can
3691         define YYDEBUG and YYERROR_VERBOSE.
3692
3693 2001-12-29  Akim Demaille  <akim@epita.fr>
3694
3695         * src/output.c (header_output): Don't forget to export YYLTYPE and
3696         yylloc.
3697         * tests/headers.at (export YYLTYPE): New, make sure it does.
3698         * tests/regression.at (%union and --defines, Invalid CPP headers):
3699         Move to...
3700         * tests/headers.at: here.
3701
3702 2001-12-29  Akim Demaille  <akim@epita.fr>
3703
3704         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3705
3706 2001-12-29  Akim Demaille  <akim@epita.fr>
3707
3708         * tests/actions.at (Mid-rule actions): Output on a single line
3709         instead of several.
3710
3711 2001-12-29  Akim Demaille  <akim@epita.fr>
3712
3713         * doc/bison.texinfo: Formatting changes.
3714
3715 2001-12-29  Akim Demaille  <akim@epita.fr>
3716
3717         Don't store the token defs in a muscle, just be ready to output it
3718         on command.  Now possible via `symbols'.  Fixes a memory leak.
3719
3720         * src/output.c (token_definitions_output): New.
3721         (output_parser, header_output): Use it.
3722         * src/reader.c (symbols_save): Remove.
3723
3724 2001-12-29  Akim Demaille  <akim@epita.fr>
3725
3726         * src/bison.simple: Do not provide a default for YYSTYPE and
3727         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3728         default.
3729
3730 2001-12-29  Akim Demaille  <akim@epita.fr>
3731
3732         Mid-rule actions are simply... ignored!
3733
3734         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3735         the empty-rule associated to the dummy symbol, not to the host
3736         rule.
3737         * tests/actions.at (Mid-rule actions): New.
3738
3739 2001-12-29  Akim Demaille  <akim@epita.fr>
3740
3741         Memory leak.
3742
3743         * src/reader.c (reader): Free grammar.
3744
3745 2001-12-29  Akim Demaille  <akim@epita.fr>
3746
3747         Memory leak.
3748
3749         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3750         since it allocates it for each state, although only one is needed.
3751         (allocate_storage): Do it here.
3752
3753 2001-12-29  Akim Demaille  <akim@epita.fr>
3754
3755         * src/options.h, src/options.c (create_long_option_table): Rename
3756         as...
3757         (long_option_table_new): this, with a clearer prototype.
3758         (percent_table): Remove, unused,
3759         * src/getargs.c (getargs): Adjust.
3760
3761 2001-12-29  Akim Demaille  <akim@epita.fr>
3762
3763         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3764         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3765         as states.
3766
3767 2001-12-29  Akim Demaille  <akim@epita.fr>
3768
3769         * src/lalr.c (build_relations): Rename `states' as `states1'.
3770         Sorry, I don't understand exactly what it is, no better name...
3771
3772 2001-12-29  Akim Demaille  <akim@epita.fr>
3773
3774         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3775         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3776         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3777         as rules.
3778
3779 2001-12-29  Akim Demaille  <akim@epita.fr>
3780
3781         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3782         ago.
3783
3784 2001-12-29  Akim Demaille  <akim@epita.fr>
3785
3786         * src/reader.c, src/reader.h (user_toknums): Remove.
3787         Adjust all users to use symbols[i]->user_token_number.
3788
3789 2001-12-29  Akim Demaille  <akim@epita.fr>
3790
3791         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3792         Adjust all users to use symbols[i]->prec or ->assoc.
3793
3794 2001-12-29  Akim Demaille  <akim@epita.fr>
3795
3796         * src/reader.c, src/reader.h (tags): Remove.
3797         Adjust all users to use symbols[i]->tag.
3798
3799 2001-12-29  Akim Demaille  <akim@epita.fr>
3800
3801         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3802         and rule_table.
3803         * src/reader.c (packsymbols): Fill this table.
3804         Drop sprec.
3805         * src/conflicts.c (resolve_sr_conflict): Adjust.
3806         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3807         single table.
3808         Use symbols[i]->tag instead of tags[i].
3809
3810 2001-12-29  Akim Demaille  <akim@epita.fr>
3811
3812         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3813         In addition, put a comment in there, to replace...
3814         * tests/regression.at (%union and C comments): Remove.
3815
3816 2001-12-29  Akim Demaille  <akim@epita.fr>
3817
3818         * tests/regression.at (Web2c Actions): Blindly move the actual
3819         output as expected output.  The contents *seem* right to me, but I
3820         can't pretend reading perfectly parser tables...  Nonetheless, all
3821         the other tests pass correctly, the table look OK, even though the
3822         presence of `$axiom' is to be noted: AFAICS it is useless (but
3823         harmless).
3824
3825 2001-12-29  Akim Demaille  <akim@epita.fr>
3826
3827         * src/reader.c (readgram): Don't add the rule 0 if there were no
3828         rules read.  In other words, add it _after_ having performed
3829         grammar sanity checks.
3830         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3831
3832 2001-12-29  Akim Demaille  <akim@epita.fr>
3833
3834         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3835         visible, and some states have now a different number.
3836
3837 2001-12-29  Akim Demaille  <akim@epita.fr>
3838
3839         * src/reader.c (readgram): Bind the initial rule's lineno to that
3840         of the first rule.
3841         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3842         (Solved SR Conflicts): Adjust rule 0's line number.
3843
3844 2001-12-29  Akim Demaille  <akim@epita.fr>
3845
3846         Fix the `GAWK Grammar' failure.
3847
3848         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3849         the reductions of the first state which was mistakenly confused
3850         with the final state because precisely final_state was initialized
3851         to 0.
3852         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3853         now noticed by Bison.
3854         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3855         have a reduction on $default.
3856
3857 2001-12-29  Akim Demaille  <akim@epita.fr>
3858
3859         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3860         rule line numbers.
3861         * src/closure.c (print_closure): Likewise.
3862         * src/derives.c (print_derives): Likewise.
3863         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3864         now.
3865
3866 2001-12-29  Akim Demaille  <akim@epita.fr>
3867
3868         * src/lalr.c (lookaheads_print): New.
3869         (lalr): Call it when --trace-flag.
3870         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3871         are dumped.
3872
3873 2001-12-29  Akim Demaille  <akim@epita.fr>
3874
3875         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3876         when walking through ritem, even via rule->rhs.
3877         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3878         (useful_production, useless_nonterminals): Likewise.
3879         (reduce_grammar_tables): Likewise, plus update nritems.
3880         * src/nullable.c (set_nullable): Likewise.
3881         * src/lalr.c (build_relations): Likewise.
3882         * tests/sets.at (Nullable): Adjust.
3883         Fortunately, now, the $axiom is no longer nullable.
3884
3885 2001-12-29  Akim Demaille  <akim@epita.fr>
3886
3887         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3888         the 0-sentinel.
3889         * src/gram.c (ritem_longest_rhs): Likewise.
3890         * src/reduce.c (nonterminals_reduce): Likewise.
3891         * src/print_graph.c (print_graph): Likewise.
3892         * src/output.c (output_rule_data): Likewise.
3893         * src/nullable.c (set_nullable):  Likewise.
3894
3895 2001-12-29  Akim Demaille  <akim@epita.fr>
3896
3897         * src/output.c: Comment changes.
3898
3899 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3900
3901         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3902         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3903         Sparc, as they were causing more porting problems than the
3904         (minor) performance improvement was worth.
3905
3906         Also, catch up with 1.31's YYSTD.
3907
3908 2001-12-27  Akim Demaille  <akim@epita.fr>
3909
3910         * src/output.c (output_gram): Rely on nritems, not the
3911         0-sentinel.  See below.
3912         Use -1 as separator, not 0.
3913         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3914         Rely on -1 as separator in yyrhs, instead of 0.
3915         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3916         twice `Now at end of input', therefore there are two lines less to
3917         expect.
3918
3919 2001-12-27  Akim Demaille  <akim@epita.fr>
3920
3921         * tests/regression.at (Unresolved SR Conflicts):
3922         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3923         below.
3924
3925 2001-12-27  Akim Demaille  <akim@epita.fr>
3926
3927         * src/LR0.c (new_state): Recognize the final state by the fact it
3928         is reached by eoftoken.
3929         (insert_start_shifting_state, insert_eof_shifting_state)
3930         (insert_accepting_state, augment_automaton): Remove, since now
3931         these states are automatically computed from the initial state.
3932         (generate_states): Adjust.
3933         * src/print.c: When reporting a rule number to the user, substract
3934         1, so that the axiom rule is rule 0, and the first user rule is 1.
3935         * src/reduce.c: Likewise.
3936         * src/print_graph.c (print_core): For the time being, just as for
3937         the report, depend upon --trace-flags to dump the full set of
3938         items.
3939         * src/reader.c (readgram): Once the grammar read, insert the rule
3940         0: `$axiom: START-SYMBOL $'.
3941         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3942         number of the states has changed (the final state is no longer
3943         necessarily the last), catch up.
3944
3945 2001-12-27  Akim Demaille  <akim@epita.fr>
3946
3947         Try to make the use of the eoftoken valid.  Given that its value
3948         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3949         is used instead of > 0 where appropriate, (ii), depend upon nritems
3950         instead of the 0-sentinel.
3951
3952         * src/gram.h, src/gram.c (nritems): New.
3953         Expected to be duplication of nitems, but for the time being...
3954         * src/reader.c (packgram): Assert nritems and nitems are equal.
3955         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3956         * src/closure.c (print_closure, print_fderives): Likewise.
3957         * src/gram.c (ritem_print): Likewise.
3958         * src/print.c (print_core, print_grammar): Likewise.
3959         * src/print_graph.c: Likewise.
3960
3961 2001-12-27  Akim Demaille  <akim@epita.fr>
3962
3963         * src/main.c (main): If there are complains after grammar
3964         reductions, then output the report anyway if requested, then die.
3965         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3966         * src/reader.c (eoftoken): New.
3967         (parse_token_decl): If the token being defined has value `0', it
3968         is the eoftoken.
3969         (packsymbols): No longer hack `tags' to insert `$' by hand.
3970         Be sure to preserve the value of the eoftoken.
3971         (reader): Make sure eoftoken is defined.
3972         Initialize nsyms to 0: now eoftoken is created just like the others.
3973         * src/print.c (print_grammar): Don't special case the eof token.
3974         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3975         lie anyway, albeit pleasant.
3976         * tests/calc.at: Exercise error messages with eoftoken.
3977         Change the grammar so that empty input is invalid.
3978         Adjust expectations.
3979         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3980
3981 2001-12-27  Akim Demaille  <akim@epita.fr>
3982
3983         * configure.in: Check the protos of strchr ans strspn.
3984         Replace strchr if needed.
3985         * src/system.h: Provide the protos of strchr, strspn and memchr if
3986         missing.
3987         * lib/strchr.c: New.
3988         * src/reader.c (symbols_save): Use strchr.
3989
3990 2001-12-27  Akim Demaille  <akim@epita.fr>
3991
3992         * src/print.c, src/print_graph.c (escape): New.
3993         Use it to quote the TAGS outputs.
3994         * src/print_graph.c (print_state): Now errors are in red, and
3995         reductions in green.
3996         Prefer high to wide: output the state number on a line of its own.
3997
3998 2001-12-27  Akim Demaille  <akim@epita.fr>
3999
4000         * src/state.h, src/state.c (reductions_new): New.
4001         * src/LR0.c (set_state_table): Let all the states have a
4002         `reductions', even if reduced to 0.
4003         (save_reductions): Adjust.
4004         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
4005         * src/print.c (print_reductions, print_actions): Adjust.
4006         * src/output.c (action_row): Adjust.
4007
4008 2001-12-27  Akim Demaille  <akim@epita.fr>
4009
4010         * src/state.h, src/state.c (errs_new, errs_dup): New.
4011         * src/LR0.c (set_state_table): Let all the states have an errs,
4012         even if reduced to 0.
4013         * src/print.c (print_errs, print_reductions): Adjust.
4014         * src/output.c (output_actions, action_row): Adjust.
4015         * src/conflicts.c (resolve_sr_conflict): Adjust.
4016
4017 2001-12-27  Akim Demaille  <akim@epita.fr>
4018
4019         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
4020
4021 2001-12-27  Akim Demaille  <akim@epita.fr>
4022
4023         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
4024         * src/print.c: here.
4025         (lookaheadset, shiftset): New, used as additional storage by
4026         print_reductions.
4027         (print_results): Adjust.
4028         (print_shifts, print_gotos, print_errs): New, extracted from...
4029         (print_actions): here.
4030         * src/print_graph.c (print_actions): Remove dead code.
4031
4032 2001-12-27  Akim Demaille  <akim@epita.fr>
4033
4034         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
4035         `$n' and `@n'.
4036
4037 2001-12-27  Akim Demaille  <akim@epita.fr>
4038
4039         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
4040         (build_relations): Adjust.
4041
4042 2001-12-27  Akim Demaille  <akim@epita.fr>
4043
4044         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
4045         duplication.
4046
4047 2001-12-27  Akim Demaille  <akim@epita.fr>
4048
4049         * src/reader.c (packgram): Catch nitems overflows.
4050
4051 2001-12-27  Akim Demaille  <akim@epita.fr>
4052
4053         * src/files.c, src/files.h (guard_obstack): Remove.
4054         * src/output.c (output): Adjust.
4055         * src/reader.c (parse_braces): New, factoring...
4056         (copy_action, copy_guard): these two which are renamed as...
4057         (parse_action, parse_guard): these.
4058         As a voluntary consequence, using braces around guards is now
4059         mandatory.
4060
4061 2001-12-27  Akim Demaille  <akim@epita.fr>
4062
4063         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
4064         * src/reader.c (symbol_list): `guard' and `guard_line' are new
4065         members.
4066         (symbol_list_new): Adjust.
4067         (copy_action): action_line is the first line, not the last.
4068         (copy_guard): Just as for actions, store the `action' only, not
4069         the switch/case/break flesh.
4070         Don't parse the user action that might follow the guard, let...
4071         (readgram): do it, i.e., now, there can be an action after a
4072         guard.
4073         In other words the guard is just explicitly optional.
4074         (packgram): Adjust.
4075         * src/output.c (guards_output): New.
4076         (output_parser): Call it when needed.
4077         (output): Also free the guard and attrs obstacks.
4078         * src/files.c, src/files.h (obstack_save): Remove.
4079         (output_files): Remove.
4080         As a result, if one needs the former `.act' file, using an
4081         appropriate skeleton which requires actions and guards is now
4082         required.
4083         * src/main.c (main): Adjust.
4084         * tests/semantic.at: New.
4085         * tests/regression.at: Use `input.y' as input file name.
4086         Avoid 8+3 problems by requiring input.c when the test needs the
4087         parser.
4088
4089 2001-12-27  Akim Demaille  <akim@epita.fr>
4090
4091         * src/reader.c (symbol_list_new): Be sure to initialize all the
4092         fields.
4093
4094 2001-12-27  Akim Demaille  <akim@epita.fr>
4095
4096         All the hacks using a final pseudo state are now useless.
4097
4098         * src/LR0.c (set_state_table): state_table holds exactly nstates.
4099         * src/lalr.c (nLA): New.
4100         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
4101         instead of lookaheadsp from the pseudo state (nstate + 1).
4102
4103 2001-12-27  Akim Demaille  <akim@epita.fr>
4104
4105         * src/output.c (action_row, token_actions): Use a state_t instead
4106         of a integer, and nlookaheads instead of the following state's
4107         lookaheadsp.
4108
4109 2001-12-27  Akim Demaille  <akim@epita.fr>
4110
4111         * src/conflicts.c (log_resolution, flush_shift)
4112         (resolve_sr_conflict, set_conflicts, solve_conflicts)
4113         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
4114         (conflicts_print, print_reductions): Use a state_t instead of an
4115         integer when referring to a state.
4116         As much as possible, depend upon nlookaheads, instead of the
4117         `lookaheadsp' member of the following state (since lookaheads of
4118         successive states are successive, the difference between state n + 1
4119         and n served as the number of lookaheads for state n).
4120         * src/lalr.c (add_lookback_edge): Likewise.
4121         * src/print.c (print_core, print_actions, print_state)
4122         (print_results): Likewise.
4123         * src/print_graph.c (print_core, print_actions, print_state)
4124         (print_graph): Likewise.
4125         * src/conflicts.h: Adjust.
4126
4127 2001-12-27  Akim Demaille  <akim@epita.fr>
4128
4129         * src/bison.hairy: Formatting/comment changes.
4130         ANSIfy.
4131         Remove `register' indications.
4132         Add plenty of `static'.
4133
4134 2001-12-27  Akim Demaille  <akim@epita.fr>
4135
4136         * src/output.c (prepare): Drop the muscle `ntbase' which
4137         duplicates ntokens.
4138         * src/bison.simple: Formatting/comment changes.
4139         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
4140         is an undocumented synonym.
4141
4142 2001-12-22  Akim Demaille  <akim@epita.fr>
4143
4144         * src/output.c (output_table_data): Change the prototype to use
4145         `int' for array ranges: some invocations do pass an int, not a
4146         short.
4147         Reported by Wayne Green.

4149 2001-12-22  Akim Demaille  <akim@epita.fr>
4150
4151         Some actions of web2c.y are improperly triggered.
4152         Reported by Mike Castle.
4153
4154         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
4155         * tests/regression.at (Web2c): Rename as...
4156         (Web2c Report): this.
4157         (Web2c Actions): New.
4158
4159 2001-12-22  Akim Demaille  <akim@epita.fr>
4160
4161         Reductions in web2c.y are improperly reported.
4162         Reported by Mike Castle.
4163
4164         * src/conflicts.c (print_reductions): Fix.
4165         * tests/regression.at (Web2c): New.
4166
4167 2001-12-18  Akim Demaille  <akim@epita.fr>
4168
4169         Some host fail on `assert (!"foo")', which expands to
4170         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
4171         Reported by Nelson Beebee.
4172
4173         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
4174         `#define it_succeeded 0' and `assert (it_succeeded)'.
4175
4176 2001-12-17  Marc Autret  <autret_m@epita.fr>
4177
4178         * src/bison.simple: Don't hard code the skeleton line and filename.
4179         * src/output.c (output_parser): Rename 'line' as 'output_line'.
4180         New line counter 'skeleton_line' (skeleton-line muscle).
4181
4182 2001-12-17  Paul Eggert  <eggert@twinsun.com>
4183
4184         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
4185         YYDEBUG must be defined to a nonzero value.
4186
4187         * src/bison.simple (yytname): Do not assume that the user defines
4188         YYDEBUG to a properly parenthesized expression.
4189
4190 2001-12-17  Akim Demaille  <akim@epita.fr>
4191
4192         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
4193         nlookaheads is a new member.
4194         Adjust all users.
4195         * src/lalr.h (nlookaheads): Remove this orphan declaration.
4196         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
4197         state.

4200
4201         * src/files.h, src/files.c (open_files, close_files): Remove.
4202         * src/main.c (main): Don't open/close files, nor invoke lex_free,
4203         let...
4204         * src/reader.c (reader): Do it.
4205
4206 2001-12-17  Akim Demaille  <akim@epita.fr>
4207
4208         * src/conflicts.c (print_reductions): Formatting changes.
4209
4210 2001-12-17  Akim Demaille  <akim@epita.fr>
4211
4212         * src/conflicts.c (flush_shift): Also adjust lookaheadset.

4214         (resolve_sr_conflict): Adjust.
4215
4216 2001-12-17  Akim Demaille  <akim@epita.fr>
4217
4218         * src/output.c (output_obstack): Be static and rename as...
4219         (format_obstack): this, to avoid any confusion with files.c's
4220         output_obstack.
4221         * src/reader.h (muscle_obstack): Move to...
4222         * src/output.h: here, since it's defined in output.c.
4223
4224 2001-12-17  Akim Demaille  <akim@epita.fr>
4225
4226         * src/output.c (action_row, save_column, default_goto)
4227         (sort_actions, matching_state, pack_vector): Better variable
4228         locality.
4229
4230 2001-12-17  Akim Demaille  <akim@epita.fr>
4231

4233
4234 2001-12-17  Akim Demaille  <akim@epita.fr>
4235
4236         * src/files.c (output_files): Free the output_obstack.
4237         * src/main.c (main): Call print and print_graph conditionally.
4238         * src/print.c (print): Work unconditionally.
4239         * src/print_graph.c (print_graph): Work unconditionally.
4240         * src/conflicts.c (log_resolution): Output only if verbose_flag.
4241
4242 2001-12-16  Marc Autret  <autret_m@epita.fr>
4243
4244         * src/output.c (actions_output): Fix. When we use %no-lines,
4245         there is one less line per action.
4246
4247 2001-12-16  Marc Autret  <autret_m@epita.fr>
4248
4249         * src/bison.simple: Remove a useless #line directive.
4250         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4251         * src/output.c (get_lines_number): New.
4252         (output_parser): Adjust, now takes care about the lines of a
4253         output muscles.
4254         Fix line numbering.
4255         (actions_output): Computes the number of lines taken by actions.
4256         (output_master_parser): Insert new skeleton which is the name of
4257         the output parser file name.
4258
4259 2001-12-15  Marc Autret  <autret_m@epita.fr>
4260
4261         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
4262
4263 2001-12-15  Marc Autret  <autret_m@epita.fr>
4264
4265         * src/output.c (output_gram): Keep track of the hairy one.
4266
4267 2001-12-15  Akim Demaille  <akim@epita.fr>
4268
4269         Make `make distcheck' work.
4270
4271         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4272         system.h which uses libgettext.h.
4273
4274 2001-12-15  Akim Demaille  <akim@epita.fr>
4275
4276         * src/nullable.c (set_nullable): Useless rules must be skipped,
4277         otherwise, since we range over their symbols, we might look at a
4278         nonterminal which no longer ``exists'', i.e., it is not counted in
4279         `nvars', hence we overflow our arrays.
4280
4281 2001-12-15  Akim Demaille  <akim@epita.fr>
4282
4283         The header can also be produced directly, without any obstack!
4284         Yahoo!
4285
4286         * src/files.c, src/files.h (defines_obstack): Remove.
4287         (compute_header_macro): Global.
4288         (defines_obstack_save): Remove.
4289         * src/reader.c (parse_union_decl): No longer output to
4290         defines_obstack: its content can be found in the `stype' muscle
4291         anyway.
4292         (output_token_translations): Merge into...
4293         (symbols_output): this.
4294         Rename as...
4295         (symbols_save): this.
4296         (reader): Adjust.
4297         * src/output.c (header_output): New.
4298         (output): Call it.
4299
4300 2001-12-15  Akim Demaille  <akim@epita.fr>
4301
4302         * src/reader.c (parse_union_decl): Instead of handling two obstack
4303         simultaneously, use one to define the `stype' muscle, and use the
4304         value of the latter to fill defines_obstack.
4305         (copy_comment): Remove.
4306         (copy_comment2): Work for a single obstack.
4307         Rename as...
4308         (copy_comment): this.
4309
4310 2001-12-15  Akim Demaille  <akim@epita.fr>
4311
4312         * src/lex.c, src/lex.h (xgetc): No longer static.
4313         * src/reader.c (parse_union_decl): Revamp.
4314
4315 2001-12-15  Akim Demaille  <akim@epita.fr>
4316
4317         Still making progress in separating Bison into (i) input, (ii)
4318         process, (iii) output: now we can directly output the parser file
4319         without using table_obstack at all.
4320
4321         * src/files.c, src/files.h (table_obstack): Bye bye.
4322         (parser_file_name): New.
4323         * src/files.c (compute_output_file_names): Compute it.
4324         * src/output.c (actions_output, output_parser)
4325         (output_master_parser): To a file instead of an obstack.
4326
4327 2001-12-15  Akim Demaille  <akim@epita.fr>
4328
4329         Attach actions to rules, instead of pre-outputting them to
4330         actions_obstack.
4331
4332         * src/gram.h (rule_t): action and action_line are new members.
4333         * src/reader.c (symbol_list): Likewise.
4334         (copy_action): Save the actions within the rule.
4335         (packgram): Save them in rule_table.
4336         * src/output.c (actions_output): New.
4337         (output_parser): Use it on `%%actions'.
4338         (output_rule_data): Don't free rule_table.
4339         (output): Do it.
4340         (prepare): Don't save the `action' muscle.
4341         * src/bison.simple: s/%%action/%%actions/.
4342
4343 2001-12-15  Akim Demaille  <akim@epita.fr>
4344
4345         * src/reader.c (copy_action): When --yacc, don't append a `;'
4346         to the user action: let it fail if lacking.
4347         Suggested by Arnold Robbins and Tom Tromey.
4348
4349 2001-12-14  Akim Demaille  <akim@epita.fr>
4350
4351         * src/lex.c (literalchar): Simply return the char you decoded, non
4352         longer mess around with obstacks and int pointers.
4353         Adjust all callers.
4354
4355 2001-12-14  Akim Demaille  <akim@epita.fr>
4356
4357         * src/lex.c (literalchar): Don't escape the special characters,
4358         just decode them, and keep them as char (before, eol was output as
4359         the 2 char string `\n' etc.).
4360         * src/output.c (output_rule_data): Use quotearg to output the
4361         token strings.
4362
4363 2001-12-13  Paul Eggert  <eggert@twinsun.com>
4364
4365         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4366         Do not infringe on the global user namespace when using C++.
4367         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4368         All uses of `fprintf' and `stderr' changed.
4369
4370         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4371
4372 2001-12-13  Akim Demaille  <akim@epita.fr>
4373
4374         The computation of nullable is broken: it doesn't handle empty
4375         RHS's properly.
4376
4377         * tests/torture.at (GNU AWK Grammar): New.
4378         * tests/sets.at (Nullable): New.
4379         * src/nullable.c (set_nullable): Instead of blindly looping over
4380         `ritems', loop over the rules, and then over their rhs's.
4381
4382         Work around Autotest bugs.
4383
4384         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4385         frame, because Autotest understand lines starting with a `+' as
4386         traces from the shell.  Then, they are not processed properly.
4387         Admittedly an Autotest bug, but we don't have time to wait for
4388         Autotest to catch up.
4389         * tests/regression.at (Broken Closure): Adjust to the new table
4390         frames.
4391         Move to...
4392         * tests/sets.at: here.
4393
4394 2001-12-13  Akim Demaille  <akim@epita.fr>
4395
4396         * src/closure.c (closure): Use nrules instead of playing tricks
4397         with BITS_PER_WORD.
4398
4399 2001-12-13  Akim Demaille  <akim@epita.fr>
4400
4401         * src/print.c (print_actions): Output the handling of `$' as the
4402         traces do: shifting the token EOF.  Before EOF was treated as a
4403         nonterminal.
4404         * tests/regression.at: Adjust some tests.
4405         * src/print_graph.c (print_core): Complete the set of items via
4406         closure.  The next-to-final and final states are still unsatisfying,
4407         but that's to be addressed elsewhere.
4408         No longer output the rule numbers, but do output the state number.
4409         A single loop for the shifts + gotos is enough, but picked a
4410         distinct color for each.
4411         (print_graph): Initialize and finalize closure.

4413 2001-12-13  Akim Demaille  <akim@epita.fr>
4414
4415         * src/reader.c (readgram): Remove dead code, an strip useless
4416         braces.
4417         (get_type): Remove, unused.
4418
4419 2001-12-12  Akim Demaille  <akim@epita.fr>
4420
4421         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4422         on that of lib/error.c.
4423
4424 2001-12-12  Akim Demaille  <akim@epita.fr>
4425
4426         Some hosts don't like `/' in includes.
4427
4428         * src/system.h: Include libgettext.h without qualifying the path.
4429         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4430         $(top_srcdir).
4431
4432 2001-12-11  Marc Autret  <autret_m@epita.fr>
4433
4434         * src/output.c (output_parser): Remove useless muscle.
4435
4436 2001-12-11  Marc Autret  <autret_m@epita.fr>
4437
4438         * src/bison.simple: Remove #line just before %%epilogue. It
4439         is now handled in ...
4440         * src/reader.c (read_additionnal_code): Add the output of a
4441         #line for the epilogue.
4442
4443 2001-12-10  Marc Autret  <autret_m@epita.fr>
4444
4445         * src/reader.c (copy_definition): Re-use CPP-outed code which
4446         replace precedent remove.
4447         * src/bison.simple: Remove #line before %%prologue because
4448         %%input-line is wrong at this time.
4449
4450 2001-12-10  Marc Autret  <autret_m@epita.fr>
4451
4452         * src/reader.c (symbols_output): Clean up.
4453         * src/output.c (output_gram, output): Clean up.
4454
4455 2001-12-10  Akim Demaille  <akim@epita.fr>
4456
4457         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
4458         * src/LR0.c (set_state_table): here.
4459         * src/lalr.c (lalr): Call it.
4460
4461 2001-12-10  Akim Demaille  <akim@epita.fr>
4462
4463         * src/state.h (shifts): Remove the `number' member: shifts are
4464         attached to state, hence no longer need to be labelled with a
4465         state number.
4466
4467 2001-12-10  Akim Demaille  <akim@epita.fr>
4468
4469         Now that states have a complete set of members, the linked list of
4470         shifts is useless: just fill directly the state's shifts member.
4471
4472         * src/state.h (shifts): Remove the `next' member.
4473         * src/LR0.c (first_state, last_state): Remove.
4474         Adjust the callers.
4475         (augment_automaton): Don't look for the shifts that must be added
4476         a shift on EOF: it is those of the state we looked for!  But now,
4477         since shifts are attached, it is no longer needed to looking
4478         merely by its id: its number.
4479
4480 2001-12-10  Akim Demaille  <akim@epita.fr>
4481
4482         * src/LR0.c (augment_automaton): Better variable locality.
4483         Remove an impossible branch: if there is a state corresponding to
4484         the start symbol being shifted, then there is shift for the start
4485         symbol from the initial state.
4486
4487 2001-12-10  Akim Demaille  <akim@epita.fr>
4488
4489         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4490         only when appropriate: when insert_start_shifting_state' is not
4491         invoked.
4492         * tests/regression.at (Rule Line Numbers): Adjust.
4493
4494 2001-12-10  Akim Demaille  <akim@epita.fr>
4495
4496         * src/LR0.c (augment_automaton): Now that all states have shifts,
4497         merge the two cases addition shifts to the initial state.
4498
4499 2001-12-10  Akim Demaille  <akim@epita.fr>
4500
4501         * src/lalr.c (set_state_table): Move to...
4502         * src/LR0.c: here.
4503         * src/lalr.c (lalr): Don't call it...
4504         * src/LR0.c (generate_states): do it.
4505         * src/LR0.h (first_state): Remove, only the table is used.
4506
4507 2001-12-10  Akim Demaille  <akim@epita.fr>
4508
4509         * src/LR0.h (first_shift, first_reduction): Remove.
4510         * src/lalr.c: Don't use first_shift: find shifts through the
4511         states.
4512
4513 2001-12-10  Akim Demaille  <akim@epita.fr>
4514
4515         * src/LR0.c: Attach shifts to states as soon as they are
4516         computed.
4517         * src/lalr.c (set_state_table): Instead of assigning shifts to
4518         state, just assert that the mapping was properly done.
4519
4520 2001-12-10  Akim Demaille  <akim@epita.fr>
4521
4522         * src/LR0.c (insert_start_shift): Rename as...
4523         (insert_start_shifting_state): this.
4524         (insert_eof_shifting_state, insert_accepting_state): New.
4525         (augment_automaton): Adjust.
4526         Better locality of the variables.
4527         When looking if the start_symbol is shifted from the initial
4528         state, using `while (... symbol != start_symbol ...)' sounds
4529         better than `while (... symbol < start_symbol ...)': If fail
4530         to see how the order between symbols could be relevant!
4531
4532 2001-12-10  Akim Demaille  <akim@epita.fr>
4533
4534         * src/getargs.h: Don't declare `spec_name_prefix' and
4535         `spec_file_prefix', declared by src/files.h.
4536         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4537         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4538         * src/output.c (prepare): Adjust.
4539         * src/reader.c (symbols_output): Likewise.
4540         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4541
4542 2001-12-10  Akim Demaille  <akim@epita.fr>
4543
4544         * src/muscle_tab.c (muscle_init): NULL is a better default than
4545         `"0"'.
4546
4547 2001-12-10  Akim Demaille  <akim@epita.fr>
4548
4549         * src/reader.c (reader): Calling symbols_output once is enough.
4550
4551 2001-12-10  Akim Demaille  <akim@epita.fr>
4552
4553         Now that states have a complete set of members, the linked list of
4554         reductions is useless: just fill directly the state's reductions
4555         member.
4556
4557         * src/state.h (struct reductions): Remove member `number' and
4558         `next'.
4559         * src/LR0.c (first_reduction, last_reduction): Remove.
4560         (save_reductions): Don't link the new reductions, store them in
4561         this_state.
4562         * src/lalr.c (set_state_table): No need to attach reductions to
4563         states, it's already done.
4564         * src/output.c (output_actions): No longer free the shifts, then
4565         the reductions, then the states: free all the states and their
4566         members.
4567
4568 2001-12-10  Akim Demaille  <akim@epita.fr>
4569
4570         * src/options.c (OPTN, DRTV, BOTH): New.
4571         (option_table): Use them.
4572
4573         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4574         the job of system.h.
4575         * src/options.c: Don't include stdio.h and xalloc.h for the same
4576         reasons.
4577
4578 2001-12-10  Akim Demaille  <akim@epita.fr>
4579
4580         * src/output.c (output, prepare): Make sure the values of the
4581         muscles `action' and `prologue' are 0-terminated.
4582
4583 2001-12-10  Akim Demaille  <akim@epita.fr>
4584
4585         Clean up GCC warnings.
4586
4587         * src/reader.c (copy_action): `buf' is not used.
4588         (parse_skel_decl): Be static.
4589         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4590         * src/options.h (create_long_option_table): Have a real prototype.
4591         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4592         (hash_delete_at): Return const void *.
4593         Adjust casts to preserve the const.
4594
4595 2001-12-10  Akim Demaille  <akim@epita.fr>
4596
4597         * configure.in: Require 2.52g.
4598         M4 is not needed, but AUTOM4TE is.
4599         * m4/m4.m4: Remove.
4600         * tests/Makefile.am: Adjust.
4601
4602 2001-12-10  Akim Demaille  <akim@epita.fr>
4603
4604         One structure for states is enough, even though theoretically
4605         there are LR(0) states and LALR(1) states.
4606
4607         * src/lalr.h (state_t): Remove.
4608         (state_table): Be state_t **, not state_t *.
4609         * src/state.h (core, CORE_ALLOC): Rename as...
4610         (state_t, STATE_ALLOC): this.
4611         Add the LALR(1) members: shifts, reductions, errs.
4612         * src/LR0.c (state_table): Rename as...
4613         (state_hash): this, to avoid name clashes with the global
4614         `state_table'.
4615         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4616         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

4620         Bison dumps core on bash.y.
4621         Reported by Pascal Bart.
4622
4623         * src/warshall.c (bitmatrix_print): New.
4624         (TC): Use it.
4625         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4626         j must be the outer loop.
4627         * tests/regression.at (Broken Closure): New.
4628
4629 2001-12-05  Akim Demaille  <akim@epita.fr>
4630
4631         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4632         its argument.
4633         Reported by Peter Hámorský.
4634
4635 2001-12-05  Akim Demaille  <akim@epita.fr>
4636
4637         * src/conflicts.c (err_table): Remove.
4638         (resolve_sr_conflict): Adjust.
4639         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4640         Rename as...
4641         (state_t.reductions, state_t.shifts): this.
4642
4643 2001-12-05  Akim Demaille  <akim@epita.fr>
4644
4645         * src/reduce.c (reduce_grammar_tables): No longer disable the
4646         removal of useless rules via CPP but via `if (0)', so that the
4647         compiler still check the code is valid.
4648         For instance, it should have noticed `rline' no longer exists: use
4649         the `line' member of rule_t.
4650         * src/gram.c (dummy, rline): Remove, unused.
4651
4652 2001-12-05  Akim Demaille  <akim@epita.fr>
4653
4654         * src/output.c (pack_vector): Use assert, not berror.
4655         * src/main.c (berror): Remove, unused.
4656
4657 2001-12-05  Akim Demaille  <akim@epita.fr>
4658
4659         New experimental feature: if --verbose --trace output all the
4660         items of a state, not only its kernel.
4661
4662         * src/print.c (print_core): If `trace_flag', then invoke closure
4663         before outputting the items of the state (print_core is no longer
4664         a correct name them).
4665         (print_results): Invoke new_closure/free_closure if needed.
4666
4667 2001-12-05  Akim Demaille  <akim@epita.fr>
4668
4669         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4670         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4671         (nitemset): for consistency with the rest of the project.
4672
4673 2001-12-05  Akim Demaille  <akim@epita.fr>
4674
4675         * src/closure.c (print_closure): Improve.
4676         (closure): Use it for printing input and output.
4677
4678 2001-12-05  Akim Demaille  <akim@epita.fr>
4679
4680         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4681         indexed by nonterminals.
4682
4683 2001-12-05  Akim Demaille  <akim@epita.fr>
4684
4685         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4686         what it was!).
4687         * src/warshall.h: Remove accidental duplication of the content.
4688
4689 2001-12-05  Akim Demaille  <akim@epita.fr>

4701 2001-12-05  Akim Demaille  <akim@epita.fr>
4702
4703         * src/output.c (action_row): De-obfuscate
4704         using the good o' techniques: arrays not pointers, variable
4705         locality, BITISSET, RESETBIT etc.
4706
4707 2001-12-05  Akim Demaille  <akim@epita.fr>
4708
4709         Pessimize the code to simplify it: from now on, all the states
4710         have a valid SHIFTS, which NSHIFTS is possibly 0.
4711
4712         * src/LR0.c (shifts_new): Be global and move to..
4713         * src/state.c, src/state.h: here.

4720         * src/conflicts.c: Use it.
4721         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4722         incorrectly ``simplified''.
4723
4724 2001-12-05  Akim Demaille  <akim@epita.fr>
4725
4726         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

4736
4737         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4738         (print_reductions): De-obfuscate using the good o' techniques:
4739         arrays not pointers, variable locality, BITISSET.
4740
4741 2001-12-05  Akim Demaille  <akim@epita.fr>

4764         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
4765         * src/lalr.c: Use them.
4766
4767 2001-12-05  Akim Demaille  <akim@epita.fr>
4768
4769         * src/LR0.c (augment_automaton): Formatting changes.
4770         Better variable locality.
4771
4772 2001-12-05  Akim Demaille  <akim@epita.fr>
4773
4774         * src/lalr.c (matrix_print): New.
4775         (transpose): Use it.
4776         Use arrays instead of pointers.
4777
4778 2001-12-05  Akim Demaille  <akim@epita.fr>
4779
4780         * src/lalr.c (maxrhs): Move to...
4781         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4782         * src/lalr.c (build_relations): Adjust.
4783
4784 2001-12-05  Akim Demaille  <akim@epita.fr>
4785
4786         * src/lalr.c (transpose): Free the memory allocated to the
4787         argument, as it is replaced by the results by the unique caller.
4788         (build_relations): Merely invoke transpose: it handles the memory
4789         deallocation.
4790         Improve variable locality.
4791         Avoid variables used as mere abbreviations.
4792         (compute_lookaheads): Use arrays instead of pointers.
4793
4794 2001-12-05  Akim Demaille  <akim@epita.fr>
4795
4796         * src/lalr.c (initialize_F): Improve variable locality.
4797         Avoid variables used as mere abbreviations.
4798
4799 2001-12-05  Akim Demaille  <akim@epita.fr>
4800
4801         * src/derives.c (print_derives): Display the ruleno.
4802         * src/lalr.c (initialize_F, transpose): Better variable locality
4803         to improve readability.
4804         Avoid variables used as mere abbreviations.
4805
4806 2001-12-05  Akim Demaille  <akim@epita.fr>
4807
4808         * src/lalr.c (traverse): Use arrays instead of pointers.
4809
4810 2001-12-05  Akim Demaille  <akim@epita.fr>
4811
4812         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4813         the handling of squeue.
4814         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4815
4816 2001-12-05  Akim Demaille  <akim@epita.fr>
4817
4818         Because useless nonterminals are now kept alive (instead of being
4819         `destroyed'), we now sometimes examine them, and store information
4820         related to them.  Hence we need to know their number, and adjust
4821         memory allocations.
4822
4823         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4824         static.
4825         * src/LR0.c (allocate_itemsets): The memory allocated to
4826         `symbol_count' was used for two different purpose: once to count
4827         the number of occurrences of each symbol, and later reassigned to
4828         `shift_symbol', containing the symbol that can be shifted from a
4829         given state.
4830         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4831         only, and...
4832         (new_itemsets): Allocate `shift_symbol' here.
4833         (allocate_itemsets): symbol_count includes useless nonterminals.
4834         Make room for them.
4835         (free_storage): Use `free', not `XFREE', for pointers that cannot
4836         be null.
4837
4838 2001-12-05  Akim Demaille  <akim@epita.fr>
4839
4840         * src/nullable.c (set_nullable): Deobfuscate the handling of
4841         ritem.
4842         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4843
4844 2001-12-05  Akim Demaille  <akim@epita.fr>
4845
4846         * src/gram.c, src/gram.h (ritem_print): New.
4847         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4848         (This useless function was defined only to work around VMS linkers
4849         that can't handle compilation units with variables only).
4850         * src/reduce.c (dump_grammar): Use it to trace the construction of
4851         ritem.
4852
4853 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4854
4855         * src/bison.simple (union yyalloc): Change member names
4856         to be the same as the stack names.
4857         (yyparse): yyptr is now union yyalloc *, not char *.
4858         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4859         and may generate better code on some machines.
4860         (yystpcpy): Use prototype if __STDC__ is defined, not just
4861         if __cplusplus is defined.
4862
4863 2001-11-30  Akim Demaille  <akim@epita.fr>
4864
4865         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4866         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4867         Gettext doesn't compile cleanly, and dies with -Werror.
4868         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4869         Include WARNING_CFLAGS here.
4870         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4871         before being defined.
4872
4873 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4874
4875         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4876         First arg is int, not unsigned.
4877         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4878         (SIZE_MAX, UINT_MAX): New macros.
4879         (quotearg_n_options): Abort if N is negative.
4880         Avoid overflow check on hosts where size_t is 64 bits and int
4881         is 32 bits, as overflow is impossible there.
4882         Fix off-by-one typo that caused unnecessary reallocation.
4883
4884 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4885
4886         Name space cleanup in generated parser.
4887
4888         * doc/bison.texinfo (Bison Parser): Discuss system headers
4889         and their effect on the user name space.
4890
4891         * src/bison.simple:
4892         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4893         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4894         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4895
4896         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4897         on user names when possible.
4898
4899         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4900         Simplify test for whather <alloca.h> exists.
4901
4902         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4903
4904         (<stdio.h>): Include if YYDEBUG.
4905
4906         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4907         ! defined (yyoverflow) && ! defined (yymemcpy).
4908
4909         (yymemcpy, yyparse): Rename local variables as needed so that
4910         they all begin with 'yy'.
4911
4912         (yystrlen, yystpcpy): New functions.
4913
4914         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4915         All uses changed.
4916
4917         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4918         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4919         and YYSTACK_FREE instead of malloc and free.
4920
4921 2001-11-30  Akim Demaille  <akim@epita.fr>
4922
4923         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4924         before their first uses.
4925         (YYBISON, YYPURE): Move to the top of the output.

4930
4931 2001-11-30  Akim Demaille  <akim@epita.fr>
4932
4933         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4934         if body instead of `;' to pacify GCC's warnings.
4935
4936 2001-11-30  Akim Demaille  <akim@epita.fr>
4937
4938         Instead of mapping the LHS of unused rules to -1, keep the LHS
4939         valid, but flag the rules as invalid.
4940
4941         * src/gram.h (rule_t): `useful' is a new member.
4942         * src/print.c (print_grammar): Adjust.
4943         * src/derives.c (set_derives): Likewise.
4944         * src/reader.c (packgram, reduce_output): Likewise.
4945         * src/reduce.c (reduce_grammar_tables): Likewise.
4946         * tests/reduce.at (Underivable Rules, Useless Rules): New.

4953         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4954
4955 2001-11-30  Akim Demaille  <akim@epita.fr>
4956
4957         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4958         useless nonterminals, move them at the end of the symbol arrays.
4959         (reduce_output): Adjust.
4960         * tests/reduce.at (Useless Nonterminals): Adjust.
4961
4962 2001-11-30  Akim Demaille  <akim@epita.fr>

4965         (nonterminals_reduce): New, extracted from...
4966         (reduce_grammar_tables): here.
4967         (reduce_grammar): Call nonterminals_reduce.
4968
4969 2001-11-29  Paul Eggert  <eggert@twinsun.com>

4972         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4973         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4974         New macros.
4975         (union yyalloc): New type.
4976         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4977         an arbitrary restriction on hosts where size_t is wider than int.
4978
4979         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4980         a parser stack overflow.  Allocate just one block of memory for all
4981         three stacks, instead of allocating three blocks; this typically is
4982         faster and reduces fragmentation.
4983
4984         Do not limit the number of items in the stack to a value that fits
4985         in 'int', as this is an arbitrary limit on hosts with 64-bit
4986         size_t and 32-bit int.
4987
4988 2001-11-29  Marc Autret  <autret_m@epita.fr>
4989
4990         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

4994 2001-11-28  Marc Autret  <autret_m@epita.fr>

5005         (prepare): Echo name modification.
5006         * src/getargs.h: Clean its extern declaration.
5007         * src/getargs.c (error_verbose_flag): Remove.
5008         (getargs): Remove case 'e'.
5009         * src/options.c (option_table): 'error-verbose' is now seen as simple
5010         percent option.

5017         option.
5018
5019 2001-11-28  Marc Autret  <autret_m@epita.fr>
5020
5021         * src/bison.simple: Adjust muscle names.
5022         * src/muscle_tab.c (muscle_init): Also rename the muscles.

5024         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
5025
5026 2001-11-28  Marc Autret  <autret_m@epita.fr>

5035
5036 2001-11-28  Akim Demaille  <akim@epita.fr>
5037
5038         * src/closure.c (closure): `b' and `ruleno' denote the same value:
5039         keep ruleno only.
5040
5041 2001-11-28  Akim Demaille  <akim@epita.fr>
5042
5043         * src/closure.c (closure): Instead of looping over word in array
5044         then bits in words, loop over bits in array.
5045
5046 2001-11-28  Akim Demaille  <akim@epita.fr>
5047
5048         * src/closure.c (closure): No longer optimize the special case
5049         where all the bits of `ruleset[r]' are set to 0, to make the code
5050         clearer.
5051
5052 2001-11-28  Akim Demaille  <akim@epita.fr>
5053
5054         * src/closure.c (closure): `r' and `c' are new variables, used to

5069         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
5070         as all tags are free'ed afterwards.
5071         From Enrico Scholz.
5072
5073 2001-11-27  Paul Eggert  <eggert@twinsun.com>
5074
5075         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
5076         use alloca when we didn't want to, and vice versa.
5077

5187         Attaching lineno to buckets is stupid, since only one copy of each
5188         symbol is kept, only the line of the first occurrence is kept too.

5443         arg_offset.
5444         arg is const.

6415         bound to true.
6416         (read_declarations): Add case for macro definition.
6417         (copy_identifier): New.
6418         (parse_macro_decl): Read macro identifiers using copy_identifier

6453         with something new. Skeletons are now processed character by character

6455         first step in making Bison's output process (a lot) more flexible.

6802         import in Bison features implemented in 2.49c since 2.13.

6836         Since we now use obstacks, more % directives can be enabled.
6837
6838         * src/lex.c (percent_table): Also accept `%yacc',
6839         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
6840         `%debug'.
6841         Handle the actions for `%semantic_parser' and `%pure_parser' here,
6842         instead of returning a token.
6843         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
6844         * src/reader.c (read_declarations): Adjust.
6845         * src/files.c (open_files): Don't call `compute_base_names', don't

6847         *in* the input file now.
6848         (output_files): Do it here.
6849         * src/output.c (output_headers): Document the fact that this patch

6875         FILE * parameters.
6876
6877 2000-12-20  Akim Demaille  <akim@epita.fr>
6878
6879         * src/files.c (open_files): Actually the `.output' file is based
6880         on the short_base_name, not base_name.
6881         * tests/suite.at (Checking output file names): Adjust.
6882
6883 2000-12-20  Akim Demaille  <akim@epita.fr>

6910         (base_names): Eve out from open_files.
6911         Try to simplify the rather hairy computation of base_name and
6912         short_base_name.

6914         * tests/suite.at (Checking output file names): New test.

6953

6986         * lib/obstack.h: Formatting changes.
6987         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6988         prevents type checking.
6989         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6990         cast the value to (void *): assigning a `foo *' to a `void *'
6991         variable is valid.
6992         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
6993         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

7030

7055         For some reason, this was not applied.
7056

7073         * src/main.c (main): Don't use `atexit' to register `done', since
7074         it no longer has to remove tmp files, just call `output_files'
7075         when there are no errors.
7076
7077 2000-11-02  Akim Demaille  <akim@epita.fr>
7078

7113         * src/files.c (faction): Remove.

7150         (copy_guard): Adjust.

7177
7178 2000-10-04  Akim Demaille  <akim@epita.fr>
7179
7180         When a literal string is used to define two different tokens,
7181         `bison -v' segfaults.
7182         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
7183
7184         * tests/regression.m4: New file.
7185         Include the core of the sample provided by Piotr Gackiewicz.

7187         properly.

7190
7191         * src/reader.c (parse_expect_decl): Keep `count' within the size

7193         From Neil Booth.
7194
7195 2000-10-02  Paul Eggert  <eggert@twinsun.com>
7196
7197         * bison.s1 (yyparse): Assign the default value
7198         unconditionally, to avoid a GCC warning and make the parser a
7199         tad smaller.
7200
7201 2000-10-02  Akim Demaille  <akim@epita.fr>
7202

7207
7208         * src/derives.c, src/print.c, src/reduce.c: To ease the

7210
7211 2000-10-02  Akim Demaille  <akim@epita.fr>
7212
7213         The location tracking mechanism is precious for parse error
7214         messages.  Nevertheless, it is enabled only when `@n' is used in
7215         the grammar, which is a different issue (you can use it in error
7216         message, but not in the grammar per se).  Therefore, there should
7217         be another means to enable it.
7218
7219         * src/getargs.c (getargs): Support `--locations'.
7220         (usage): Report it.
7221         * src/getargs.h (locationsflag): Export it.
7222         * src/lex.c (percent_table): Support `%locations'.
7223         * src/reader.c (yylsp_needed): Remove this variable, now replaced
7224         with `locationsflag'.
7225         * doc/bison.texinfo: Document `--locations' and `%locations'.
7226         Sort the options.
7227         * tests/calc.m4: Test it.
7228
7229         For regularity of the names, replace each
7230         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
7231         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
7232         In addition replace each `flag' with `_flag'.
7233
7234 2000-10-02  Akim Demaille  <akim@epita.fr>
7235
7236         Also test parse error messages, including with YYERROR_VERBOSE.
7237
7238         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7239         associative).
7240         Use it to check the computations.
7241         Use it to check `nonassoc' is honored.
7242         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7243         `--yyerror-verbose'.
7244         (_AT_CHECK_CALC): Adjust to this option.
7245         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7246
7247 2000-10-02  Akim Demaille  <akim@epita.fr>
7248
7249         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
7250         the latter demonstrates a flaw in the handling of non debugging
7251         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7252         was used in order to simplify:
7253
7254         #if YYDEBUG
7255         if (yydebug)
7256         {
7257         ...
7258         }
7259         #endif
7260
7261         into
7262
7263         if (yydebug)
7264         {
7265         ...
7266         }
7267
7268         unfortunately this leads to a CPP conflict when
7269         `--name-prefix=foo' is used since it produces `#define yydebug
7270         foodebug'.
7271
7272         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7273         (YYDPRINTF): New macro.
7274         Spread its use.
7275         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7276         the bison options.
7277         Also test `--verbose', `--defines' and `--name-prefix'.

7284         Improve the comment related to the `$' mark.
7285         (yydefault): Don't fall through to `yyresume': `goto' there.
7286         * src/output.c (output_parser): When the `$' is met, skip the end
7287         of its line.
7288         New variable, `number_of_dollar_signs', to check there's exactly
7289         one `$' in the parser skeleton.
7290
7291 2000-10-02  Akim Demaille  <akim@epita.fr>
7292
7293         * lib/xstrdup.c: New file, from the fileutils.
7294         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7295         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7296         instead of strlen + xmalloc + strcpy.

7298
7299 2000-10-02  Akim Demaille  <akim@epita.fr>
7300
7301         * src/gram.h (associativity): New enum type which replaces the
7302         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7303         `right_assoc', `left_assoc' and `non_assoc'.
7304         Adjust all dependencies.
7305         * src/reader.c: Formatting changes.

7307         `reader_output_yylsp'.
7308         * src/symtab.h (symbol_class): New enum type which replaces the
7309         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7310         `sunknown', `stoken and `snterm'.

7317
7318 2000-10-02  Akim Demaille  <akim@epita.fr>
7319
7320         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7321         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
7322         difficult and introduced a lot of core dump.  It turns out that
7323         Bison used an implementation of `xmalloc' based on `calloc', and
7324         at various places it does depend upon the initialization to 0.  I
7325         have not tried to isolate the pertinent places, and all the former
7326         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
7327         someone should address this issue.
7328
7329         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7330         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

7423
7424         * src/output.c (token_actions): Introduce a temporary array,
7425         YYDEFACT, that makes it possible for this function to use

7429
7430         `user_toknums' is output as a `short[]' in `output.c', while it is
7431         defined as a `int[]' in `reader.c'.  For consistency with the
7432         other output tables, `user_toknums' is now defined as a table of
7433         shorts.
7434
7435         * src/reader.c (user_toknums): Be a short table instead of an int
7436         table.

7448         order to get rid of the `static' prototypes.

7450         * src/output.h: New file.
7451         Propagate its inclusion in files explicitly prototyping functions
7452         from output.c.

7474         inclusion.
7475         Don't define PARAMS.
7476         * src/system.h: Define PARAMS.
7477         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7478         purpose of config.h.  system.h must not try to fix wrong
7479         definitions in config.h.

7639
7640         * src/Makefile.am (bison.simple): Fix the awk program: quote only
7641         the file name, not the whole `#line LINE FILE'.
7642
7643 2000-03-17  Akim Demaille  <akim@epita.fr>
7644
7645         On syntax errors, report the token on which we choked.

7667         copy_comment.  Removed now unused `match', `ended',
7668         `cplus_comment'.
7669         (copy_comment, copy_string): Moved, to be visible from
7670         copy_definition.
7671

7673

7696
7697         Change the handling of @s so that they behave exactly like $s.
7698         There is now a pseudo variable @$ (readble and writable), location
7699         of the lhs of the rule (by default ranging from the location of
7700         the first symbol of the rhs, to the location of the last symbol,
7701         or, if the rhs is empty, YYLLOC).
7702
7703         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7704         yyval.
7705         (yyparse): When providing a default semantic action, provide a
7706         default location action.
7707         (after the $): No longer change `*YYLSP', just stack YYLOC the
7708         same way you stack YYVAL.
7709         * src/reader.c (read_declarations): Use warns.
7710         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7711         (copy_action, case '@'): Likewise.
7712         Use a standard error message, to save useless work from
7713         translators.
7714
7715 2000-03-17  Akim Demaille  <akim@epita.fr>
7716

7734
7735         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7736         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7737         One `#if YYDEBUG' remains, since it uses variables which are
7738         defined only if `YYDEBUG != 0'.
7739
7740 2000-03-16  Akim Demaille  <akim@epita.fr>

7764         handled via src/Makefile.am.

7766         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

7772         the proper line number and file name.
7773         (DEFS): Propagate the location of bison library files and of the
7774         locale files.
7775         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7776         builddir.
7777         * acinclude.m4: Remove, replaced by the directory m4.
7778         * m4/Makefile.am (EXTRA_DIST): New variable.
7779         * m4/gettext.m4: New file, from the fileutils.

8411         (readgram): Use `#if 0' around code that accepted %command
8412         inside grammar rules:  The documentation doesn't allow it,
8413         and it will fail since the %command processors scan for the next %.
8414         (parse_token_decl):  Extended the %token
8415         declaration to allow a multi-character symbol as an alias.

8424         (get_type_name, copy_guard, copy_action, readgram)
8425         (get_type, packsymbols):  Revised most error messages.
8426         Changed `fatal' to `warnxxx' to avoid aborting for error.
8427         Revised and use multiple warnxxx functions to avoid using VARARGS1.
8428         (read_declarations): Improve the error message for
8429         an invalid character.  Do not abort.
8430         (read_declarations, copy_guard, copy_action): Use
8431         printable_version to avoid unprintable characters in printed output.
8432         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
8433         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
8434         Allow the type of a non-terminal can be given
8435         more than once, as long as all specifications give the same type.
8436
8437         * src/output.c:
8438         (output_headers, output_trailers, output, output_gram)
8439         (output_rule_data): Implement noparserflag variable.
8440         Implement toknumflag variable.
8441         (output): Call reader_output_yylsp to output LTYPESTR.
8442
8443         * src/main.c (main):
8444          If reader sees an error, don't process the grammar.
8445         (fatals): Updated to not use VARARGS1.
8446         (printable_version, int_to_string, warn, warni, warns, warnss)
8447         (warnsss): New error reporting functions.  Avoid abort for error.
8448
8449         * src/lex.h:
8450         Added THONG and NOOP for alias processing.
8451         Added SETOPT for the new code that allows setting options with %flags.
8452
8453         * src/lex.c:

8455         (safegetc): New function to deal with EOF gracefully.
8456         (literalchar); new function to deal with reading \ escapes.
8457         (lex): Use literalchar.
8458         (lex): Implemented "..." tokens.
8459         (literalchar, lex, parse_percent_token): Made tokenbuffer
8460         always contain the token.  This includes growing the token
8461         buffer while reading an integer.
8462         (parse_percent_token): Replaced if-else statement with percent_table.
8463         (parse_percent_token): Added % declarations as another
8464         way to specify the flags -n, -l, and -r.  Also added hooks for
8465         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
8466         major changes to files.c.
8467         (lex) Retain in the incoming stream a character following
8468         an incorrect '/'.
8469         (skip_white_space, lex):  Revised most error messages
8470         and changed fatal to warn to avoid aborting.
8471         (percent_table):  Added %thong declarations.
