   2
   3         Version 1.75.
   4
   5 2002-10-14  Akim Demaille  <akim@epita.fr>
   6
   7         * tests/Makefile.am (maintainer-check-posix): New.
   8
   9 2002-10-14  Akim Demaille  <akim@epita.fr>
  10
  11         * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
  12         member.
  13
  14 2002-10-14  Akim Demaille  <akim@epita.fr>
  15
  16         * src/tables.c (table_ninf_remap): base -> tab.
  17         Reported by Matt Rosing.
  18
  19 2002-10-14  Paul Eggert  <eggert@twinsun.com>
  20
  21         * tests/action.at, tests/calc.at, tests/conflicts.at,
  22         tests/cxx-type.at, tests/headers.at, tests/input.at,
  23         tests/regression.at, tests/synclines.at, tests/torture.at:
  24         Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
  25         so that the tests still work even if POSIXLY_CORRECT is set.
  26         * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
  27
  28         * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
  29         for portability to K&R hosts.  Fix typo: signed char is guaranteed
  30         only to 127, not to 128.
  31         * data/glr.c (yysigned_char): New type.
  32         * data/yacc.c (yysigned_char): Likewise.
  33         * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
  34
  35 2002-10-13  Paul Eggert  <eggert@twinsun.com>
  36
  37         * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
  38         true due to limited range of data type" warning from GCC.
  39
  40         * data/c.m4 (b4_token_defines): Protect against double-inclusion
  41         by wrapping enum yytokentype's definition inside #ifndef
  42         YYTOKENTYPE.  This undoes a bug I introduced on 2002-10-12.
  43
  44 2002-10-13  Akim Demaille  <akim@epita.fr>
  45
  46         * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
  47         Un yy- yyrhs to avoid the name clash with the global YYRHS.
  48
  49 2002-10-13  Akim Demaille  <akim@epita.fr>
  50
  51         * Makefile.maint: Update from Autoconf 2.54.
  52         * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
  53
  54 2002-10-13  Akim Demaille  <akim@epita.fr>
  55
  56         * src/print.c (print_state): Separate the list of solved conflicts
  57         from the other items.
  58         * tests/conflicts.at (Resolved SR Conflicts): Adjust.
  59
  60 2002-10-13  Akim Demaille  <akim@epita.fr>
  61
  62         Let nondeterministic skeletons be usable with deterministic
  63         tables.
  64
  65         With the patch, GAWK compiled by GCC without -O2 passes its test
  66         suite using a GLR parser driven by LALR tables.  It fails with -O2
  67         because `struct stat' gives two different answers on my machine:
  68         88 (definition of an auto var) and later 96 (memset on this var).
  69         Hence the stack is badly corrumpted.  The headers inclusion is to
  70         blame: if I move the awk.h inclusion before GLR's system header
  71         inclusion, the two struct stat have the same size.
  72
  73         * src/tables.c (pack_table): Always create conflict_table.
  74         (token_actions): Always create conflict_list.
  75         * data/glr.c (YYFLAG): Remove, unused.
  76
  77 2002-10-13  Akim Demaille  <akim@epita.fr>
  78
  79         * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
  80         (O0FLAGS): New.
  81         (VALGRIND, GXX): New.
  82         * tests/atlocal.in (CFLAGS): Use O0FLAGS.
  83         * tests/bison.in: Run $PREBISON a pre-command.
  84         * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
  85         (maintainer-check-g++): New.
  86         * Makefile.am (maintainer-check): New.
  87
  88 2002-10-13  Akim Demaille  <akim@epita.fr>
  89
  90         * data/glr.c: Formatting changes.
  91         Tweak some trace messages to match yacc.c's.
  92
  93 2002-10-13  Akim Demaille  <akim@epita.fr>
  94
  95         GLR parsers sometimes raise parse errors instead of performing the
  96         default reduction.
  97         Reported by Charles-Henry de Boysson.
  98
  99         * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
 100         check the length of the traces when %glr.
 101         (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
 102         GLR's traces.
 103         (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
 104         Test GLR parsers.
 105         * data/glr.c (YYLEFTMOST_STATE): Fix its value.
 106         (yyltype): Remove the yy prefix from the member names.
 107         (yytable): Complete its comment.
 108         (yygetLRActions): Map error action number from YYTABLE from
 109         YYTABLE_NINF to 0.
 110         (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
 111         (which was a bug: it should have been YYTABEL_NINF, and yet it was
 112         not satisfying as we could compare an YYACTION computed from
 113         YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
 114         only value for error actions.
 115         (yyreportParseError): In verbose parse error messages, don't issue
 116         `error' in the list of expected tokens.
 117         * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
 118         next action to perform to match glr.c's decoding.
 119         (yytable): Complete its comment.
 120
 121 2002-10-13  Paul Eggert  <eggert@twinsun.com>
 122
 123         Fix problem reported by Henrik Grubbstroem in
 124         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
 125         "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
 126         because the Bison parser reads the second action before reducing
 127         the first one.
 128         * src/scan-gram.l (rule_length): New static var.
 129         Use it to keep track of the rule length in the scanner, since
 130         we can't expect the parser to be in lock-step sync with the scanner.
 131         (handle_action_dollar, handle_action_at): Use this var.
 132         * tests/actions.at (Exotic Dollars): Test for the problem.
 133
 134 2002-10-12  Paul Eggert  <eggert@twinsun.com>
 135
 136         * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
 137         * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
 138         Include <sys/time.h> when checking for clock_t and struct tms.
 139         Use same include order as source.
 140         This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
 141         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
 142
 143         * lib/timevar.c: Update copyright date and clarify comments.
 144         (get_time) [IN_GCC]: Keep the GCC version for reference.
 145
 146         * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
 147         GCC version as of today, then merge Bison's changes.
 148         Change "GCC" to "Bison" in copyright notice.  timevar.def's
 149         author is Akim, so change that too.
 150
 151         * src/reader.c (grammar_current_rule_check):
 152         Don't worry about the default action if $$ is untyped.
 153         Prevents bogus warnings reported by Jim Gifford in
 154         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
 155
 156         * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
 157         * data/glr.c, data/lalr1.cc, data/yacc.c:
 158         Output token definitions before the first part of user declarations.
 159         Fixes compatibility problem reported by Jim Gifford for kbd in
 160         <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
 161
 162 2002-10-11  Paul Eggert  <eggert@twinsun.com>
 163
 164         * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
 165         (yyparse): here.  This undoes some of the 2002-07-25 change.
 166         Compatibility problem reported by Ralf S. Engelschall with
 167         OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
 168
 169 2002-10-11  Akim Demaille  <akim@epita.fr>
 170
 171         * tests/regression.at Characters Escapes): New.
 172         * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
 173         characters.
 174         Reported by Jan Nieuwenhuizen.
 175
 176 2002-10-11  Akim Demaille  <akim@epita.fr>
 177
 178         * po/id.po: New.
 179
 180 2002-10-10  Paul Eggert  <eggert@twinsun.com>
 181
 182         Portability fixes for bitsets; this also avoids several GCC
 183         warnings.
 184
 185         * lib/abitset.c: Include <stddef.h>, for offsetof.
 186         * lib/lbitset.c: Likewise.
 187
 188         * lib/abitset.c (abitset_bytes): Return a size that is aligned
 189         properly for vectors of objects.  Do not assume that adding a
 190         header size to a multiple of a word size yields a value that is
 191         properly aligned for the whole union.
 192         * lib/bitsetv.c (bitsetv_alloc): Likewise.
 193
 194         * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
 195         unique names for structures.
 196         * lib/ebitset.c (ebitset_bytes): Likewise.
 197         * lib/lbitset.c (lbitset_bytes): Likewise.
 198
 199         * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
 200         abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
 201         abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
 202         abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
 203         abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
 204         abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
 205         abitset_or_and_cmp, abitset_copy): Supply prototype decls,
 206         to improve the type-checking that GCC can do.
 207         * lib/bitset.c (bitset_op4_cmp): Likewise.
 208         * lib/bitset_stats.c (bitset_stats_count,
 209         bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
 210         bitset_stats_copy, bitset_stats_disjoint_p,
 211         bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
 212         bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
 213         bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
 214         bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
 215         bitset_stats_and_or_cmp, bitset_stats_andn_or,
 216         bitset_stats_andn_or_cmp, bitset_stats_or_and,
 217         bitset_stats_or_and_cmp): Likewise.
 218         * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
 219         lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
 220         lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
 221         lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
 222
 223         * lib/abitset.h: Include bitset.h, not bbitset.h.
 224         * lib/ebitset.h: Likewise.
 225         * lib/lbitset.h: Likewise.
 226
 227         * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
 228         All instances of parameters of type enum bitset_opts are now of
 229         type enum_bitset_opts, to conform to the C Standard, and similarly
 230         for enum_bitset_type.
 231         * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
 232         * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
 233
 234         Do not use "struct bitset_struct" to mean different things in
 235         different modules.  Not only is this confusing, it violates
 236         the C Standard, which requires that structure types in different
 237         modules must be compatible if one is to be passed to the other.
 238         * lib/bbitset.h (bitset): Now points to a union, not to a struct.
 239         All instances of "struct bitset_struct *" replaced with "bitset".
 240         * lib/bitset.h (struct bitset_struct): Remove, replacing with....
 241         (union bitset_union, struct abitset_struct, struct ebitset_struct,
 242         struct lbitset_struct, struct bitset_stats_struct): New types.
 243         All uses of struct bitset_struct changed to union bitset_union,
 244         etc.
 245         * lib/abitset.c (struct abitset_struct, abitset,
 246         struct bitset_struct): Remove.
 247         * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
 248         struct bitset_struct): Remove.
 249         * lib/ebitset.c (struct ebitset_struct, ebitset, struct
 250         bitset_struct): Remove.
 251         * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
 252         Likewise.
 253
 254         Do not call a function of type T using a call that assumes the
 255         function is of a different type U.  Standard C requires that a
 256         function must be called with a type that is compatible with its
 257         definition.
 258         * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 259         New decls.
 260         * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
 261         New functions.
 262         * lib/ebitset.c (PFV): Remove.
 263         * lib/lbitset.c (PFV): Likewise.
 264         * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
 265         ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
 266         decls.
 267         (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
 268         (ebitset_vtable): Use them.
 269         * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
 270         lbitset_xor): New functions.
 271         (lbitset_vtable): Use them.
 272
 273         * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
 274         Declare.
 275
 276         * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
 277         GCC warning.
 278         * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
 279         Use offsetof, for simplicity.
 280
 281 2002-10-06  Paul Eggert  <eggert@twinsun.com>
 282
 283         * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
 284         the same width as int.  This reapplies a hunk of the 2002-08-12 patch
 285         <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
 286         which was inadvertently undone by the 2002-09-30 patch.
 287         * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
 288         the same width as int.
 289
 290 2002-10-04  Paul Eggert  <eggert@twinsun.com>
 291
 292         Version 1.50.
 293
 294         * configure.ac (AC_INIT), NEWS: Increment version number.
 295
 296         * doc/bison.texinfo: Minor spelling, grammar, and white space
 297         fixes.
 298         (Symbols): Mention that any negative value returned from yylex
 299         signifies end-of-input.  Warn about negative chars.  Mention
 300         the portable Standard C character set.
 301
 302         The GNU coding standard says CFLAGS and YFLAGS are reserved
 303         for the installer to set.
 304         * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
 305         * src/Makefile.am (AM_CFLAGS): Likewise.
 306         (AM_YFLAGS): Renamed from YFLAGS.
 307
 308         Fix some MAX and MIN problems.
 309         * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
 310         * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
 311         * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
 312         * src/reader.c (reader): Use it.
 313
 314         * tests/regression.at (Braces parsing): Use grep, not fgrep, as
 315         POSIX 1003.1-2001 has removed fgrep.
 316
 317 2002-10-04  Michael Hayes  <m.hayes@elec.canterbury.ac.nz>
 318
 319         * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
 320         interpreted as signed.
 321         * lib/ebitset.c (ebitset_list): Fix bug.
 322
 323 2002-10-01  Paul Eggert  <eggert@twinsun.com>
 324
 325         More fixes for 64-bit hosts and large bitsets.
 326

 508 2002-09-04  Jim Meyering  <jim@meyering.net>

 531         * NEWS: Mention that GNU M4 is now required.  Clarify what is

 544         (yy_yypstack): No longer nested inside yypstates, as nested
 545         functions are not portable.  Do not assume size_t is the
 546         same width as int.
 547         (yypstates): Do not assume that ptrdiff_t is the same width
 548         as int, and similarly for yyposn and YYINDEX.
 549
 550         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 551
 552         * lib/Makefile.am (INCLUDES): Do not include from the intl
 553         directory, which has been removed.

 588
 589         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 590         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 591         check for void *.
 592
 593         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 594         size_t; the old version tried to do this but casted improperly.
 595         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 596         (bitset_test): Now returns int, not unsigned long.

 599         (_): New macro.
 600         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 601         name locals "index", as it generates unnecessary warnings on some
 602         hosts that have an "index" function.
 603
 604         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 605         bitset_stats_read, bitset_stats_write): Wrap strings in _() if

 623
 624         * po/LINGUAS: Add pt_BR.

 626         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 627         lib/timevar.c.
 628         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 629         manual recommends.
 630         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 631
 632         * src/complain.c (strerror_r): Remove decl; not needed.

 638
 639         * src/main.c (main): Cast result of bindtextdomain and textdomain
 640         to void, to avoid a GCC warning when --disable-nls is in effect.
 641
 642         * src/scan-gram.l: Use strings rather than escapes when possible,
 643         to minimize the number of warnings from xgettext.
 644         (handle_action_dollar, handle_action_at): Don't use isdigit,
 645         as it mishandles negative chars and it may not work as expected
 646         outside the C locale.
 647
 648         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 649         this is a GCC extension and is not portable to other compilers.
 650
 651         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 652         Do not include <ctype.h>; no longer needed.
 653         Do not include <malloc.h>; no longer needed (and generates

 790         * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
 791         (long_options, short_options): --trace/-T takes an optional

 828         by conflicts.
 829
 830         * src/LR0.c (save_reductions): Don't make the final state too
 831         different: save its reduction (accept) instead of having a state
 832         without any action (no shift or goto, no reduce).
 833         Note: the final state is now a ``regular'' state, i.e., the
 834         parsers now contain `reduce 0' as default reduction.
 835         Nevertheless, since they decide to `accept' when yystate =
 836         final_state, they still will not reduce rule 0.

 888         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
 889         for the time being: %locations ought to provide it to yyerror.

 891 2002-07-25  Akim Demaille  <akim@epita.fr>

2408         * src/lex.h (token_t): remove tok_guard.
2409         * src/options.c (option_table): Remove %guard and %semantic_parser
2410         support.

2426
2427         * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
2428         (parse_guard): Rename the formal argument `stack_offset' as
2429         `rule_length', which is more readable.
2430         Adjust callers.
2431         (copy_at, copy_dollar): Instead of outputting the hard coded
2432         values of $$, $n and so forth, output invocation to b4_lhs_value,
2433         b4_lhs_location, b4_rhs_value, and b4_rhs_location.
2434         Note: this patch partially drops `semantic-parser' support: it
2435         always does `rule_length - n', where semantic parsers ought to
2436         always use `-n'.
2437         * data/bison.simple, data/bison.c++ (b4_lhs_value)
2438         (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

2468         * src/reader.c (copy_character): New function, used to output
2469         single characters while replacing `[' and `]' with quadrigraphs, to

2487
2488         * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
2489         `b4_post_prologue' instead of `b4_prologue'.
2490
2491         * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
2492         muscles.
2493         (output): Free pre_prologue_obstack and post_prologue_obstack.

2496         * src/reader.c (copy_definition): Add a parameter to specify the
2497         obstack to fill, instead of using attrs_obstack unconditionally.
2498         (read_declarations): Pass pre_prologue_obstack to copy_definition if
2499         `%union' has not yet been seen, pass post_prologue_obstack otherwise.

2508         YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
2509         if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial

2542
2543         * src/reader.c (token_translations_init): 256 is now the default
2544         value for the error token, i.e., it will be assigned another
2545         number if the user assigned 256 to one of her tokens.

2550         etc. instead of 10, 20, 30 (which was used to `jump' over error

2552
2553 2002-04-22  Akim Demaille  <akim@epita.fr>

2587
2588 2002-04-09  Akim Demaille  <akim@epita.fr>
2589
2590         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2591         full stderr, and strip it according to the bison options, instead
2592         of composing the error message from different bits.
2593         This makes it easier to check for several error messages.
2594         Adjust all the invocations.
2595         Add an invocation exercising the error token.
2596         Add an invocation demonstrating a stupid error message.

2604         errtoken->number.
2605         * src/reader.c (reader): Don't specify the user token number (2)
2606         for $undefined, as it uselessly prevents using it.
2607         * src/gram.h (token_number_t): Move to...
2608         * src/symtab.h: here.
2609         (state_t.number): Is a token_number_t.
2610         * src/print.c, src/reader.c: Use undeftoken->number instead of
2611         hard coded 2.
2612         (Even though this 2 is not the same as above: the number of the
2613         undeftoken remains being 2, it is its user token number which
2614         might not be 2).
2615         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2616         `user_token_number_max'.
2617         Output `undef_token_number'.
2618         * data/bison.simple, data/bison.c++: Use them.
2619         Be sure to map invalid yylex return values to
2620         `undef_token_number'.  This saves us from gratuitous SEGV.
2621
2622         * tests/conflicts.at (Solved SR Conflicts)
2623         (Unresolved SR Conflicts): Adjust.

2639         RITEM.  Note that it must be able to code symbol numbers as
2640         positive number, and the negation of rule numbers as negative
2641         numbers.
2642         Adjust all dependencies (pretty many).
2643         * src/reduce.c (rule): Remove this `short *' pointer: use
2644         item_number_t.
2645         * src/system.h (MINSHORT, MAXSHORT): Remove.
2646         Include `limits.h'.
2647         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2648         (shortcpy): Remove.
2649         (MAXTABLE): Move to...
2650         * src/output.c (MAXTABLE): here.
2651         (prepare_rules): Use output_int_table to output rhs.
2652         * data/bison.simple, data/bison.c++: Adjust.
2653         * tests/torture.at (Big triangle): Move the limit from 254 to
2654         500.
2655         * tests/regression.at (Web2c Actions): Ajust.
2656
2657         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2658         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2659         passes, but produces negative #line number, once fixed, GCC is
2660         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2661         C), it passes.
2662         * src/state.h (state_h): Code input lines on ints, not shorts.
2663
2664 2002-04-08  Akim Demaille  <akim@epita.fr>

2679         New.
2680         Use them to define yy_token_number_type/TokenNumberType.
2681         Use this type for yytranslate.
2682         * tests/torture.at (Big triangle): Push the limit from 124 to

2790 2002-04-07  Akim Demaille  <akim@epita.fr>
2791
2792         Be sure never to walk through RITEMS, but use only data related to

2794
2795         * src/output.c (output_token_translations): Rename as...
2796         (prepare_tokens): this.
2797         In addition to `translate', prepare the muscles `tname' and

2815         (new_states): Create the itemset of the initial state, and use
2816         new_state.
2817         * src/closure.c (closure): Now that the initial state has its
2818         items properly set, there is no need for a special case when
2819         creating `ruleset'.
2820
2821         As a result, now the rule 0, reducing to $axiom, is visible in the

2844         * src/symtab.h: here.
2845         No longer include `gram.h'.

2854         the end of `rules', and count them out of `nrules'.
2855         (reduce_output, dump_grammar): Adjust.
2856         * src/print.c (print_grammar): It is no longer needed to check for
2857         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
2858         * tests/reduce.at (Reduced Automaton): New test.
2859
2860 2002-04-07  Akim Demaille  <akim@epita.fr>
2861
2862         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
2863         lacking `+ 1' to nrules, Bison reported as useless a token if it
2864         was used solely to set the precedence of the last rule...
2865
2866 2002-04-07  Akim Demaille  <akim@epita.fr>
2867
2868         * data/bison.c++, data/bison.simple: Don't output the current file
2869         name in #line, to avoid useless diffs between two identical
2870         outputs under different names.

3160 2002-02-14  Paul Eggert  <eggert@twinsun.com>
3161
3162         Remove the support for C++ namespace cleanliness; it was
3163         causing more problems than it was curing, since it didn't work
3164         properly on some nonstandard C++ compilers.  This can wait
3165         for a proper C++ parser.
3166
3167         * NEWS: Document this.
3168         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

3255         (token_definitions_output): No longer keeps track of the output
3256         line number, hence remove the second argument.
3257         (guards_output): Check against the guard member of a rule, not the
3258         action member.
3259         Adjust callers.

3263         file will be used.
3264         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3265         (prepare): Given that for the time being changesyntax is not
3266         usable in M4, rename the muscles using `-' to `_'.

3274         to date.
3275         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
3276         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.

3394         (prefix): Remove too.
3395         * src/scan-skel.l: Adjust.
3396         * src/bison.simple, src/bison.hairy: Adjust.
3397
3398 2002-01-09  Akim Demaille  <akim@epita.fr>
3399
3400         * configure.in (WERROR_CFLAGS): Compute it.
3401         * src/Makefile.am (CFLAGS): Pass it.
3402         * tests/atlocal.in (CFLAGS): Idem.
3403         * src/files.c: Fix a few warnings.
3404         (get_extension_index): Remove, unused.
3405
3406 2002-01-08  Akim Demaille  <akim@epita.fr>
3407
3408         * src/getargs.c (AS_FILE_NAME): New.
3409         (getargs): Use it to convert DOSish file names.
3410         * src/files.c (base_name): Rename as full_base_name to avoid
3411         clashes with `base_name ()'.
3412         (filename_split): New.
3413         (compute_base_names): N-th rewrite, using filename_split.
3414
3415 2002-01-08  Akim Demaille  <akim@epita.fr>
3416
3417         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3418         New, stolen from the Fileutils 4.1.
3419         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3420         * configure.in: Check for the presence of memrchr, and of its
3421         prototype.
3422
3423 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3424
3425         * lib/hash.h (__P): Added definition for this macro.
3426         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3427         BUILT_SOURCES, to ensure they are generated first.
3428         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3429         %error-verbose to allow bootstrapping with bison 1.30x.
3430
3431 2002-01-06  Akim Demaille  <akim@epita.fr>
3432
3433         * src/reader.c (parse_braces): Don't fetch the next char, the
3434         convention is to fetch on entry.
3435         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3436         'switch' without a following semicolon.
3437         * tests/regression.at (braces parsing): New.
3438
3439 2002-01-06  Akim Demaille  <akim@epita.fr>
3440
3441         Bison is dead wrong in its RR conflict reports.
3442
3443         * tests/torture.at (GNU Cim Grammar): New.
3444         * src/conflicts.c (count_rr_conflicts): Fix.
3445
3446 2002-01-06  Akim Demaille  <akim@epita.fr>
3447
3448         Creating package.m4 from configure.ac causes too many problems.
3449
3450         * tests/Makefile.am (package.m4): Create it by hand,
3451         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3452
3453 2002-01-06  Akim Demaille  <akim@epita.fr>
3454
3455         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3456         skeleton.h.
3457
3458 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3459
3460         * doc/bison.texinfo (Debugging):
3461         Remove YYSTDERR; it's no longer defined or used.
3462         Also, s/cstdio.h/cstdio/.
3463
3464 2002-01-03  Akim Demaille  <akim@epita.fr>
3465
3466         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3467
3468 2002-01-03  Akim Demaille  <akim@epita.fr>
3469
3470         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3471         tracing code to --trace, wait for a better --trace option, with
3472         args.
3473
3474 2002-01-03  Akim Demaille  <akim@epita.fr>
3475
3476         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3477         The ISO C++ standard is extremely clear about it: stderr is
3478         considered a macro, not a regular symbol (see table 94 `Header
3479         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3480         Therefore std:: does not apply to it.  It still does with fprintf.
3481         Also, s/cstdio.h/cstdio/.
3482
3483 2002-01-03  Akim Demaille  <akim@epita.fr>
3484
3485         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3486         for non system headers.
3487
3488 2002-01-02  Akim Demaille  <akim@epita.fr>
3489
3490         Equip the skeleton chain with location tracking, runtime trace,
3491         pure parser and scanner.
3492
3493         * src/parse-skel.y: Request a pure parser, locations, and prefix
3494         renaming.
3495         (%union): Having several members with the same type does not help
3496         type mismatches, simplify.
3497         (YYPRINT, yyprint): New.
3498         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3499         (skel_error): this.
3500         Handle locations.
3501         * src/scan-skel.l: Adjust to these changes.
3502         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3503         (LOCATION_PRINT, skel_control_t): New.
3504
3505 2001-12-30  Akim Demaille  <akim@epita.fr>
3506
3507         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3508         replace `gb' with BLANKS.
3509         * src/scan-skel.l: Adjust.
3510
3511 2001-12-30  Akim Demaille  <akim@epita.fr>
3512
3513         * src/system.h: We don't need nor want bcopy.
3514         Throw away MS-DOS crap: we don't need getpid.
3515         * configure.in: We don't need strndup.  It was even causing
3516         problems: because Flex includes the headers *before* us,
3517         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3518         not visible.
3519         * lib/xstrndup.c: New.
3520         * src/scan-skel.l: Use it.
3521         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3522         * src/parse-skel.y: Use %directives instead of #defines.
3523
3524 2001-12-30  Akim Demaille  <akim@epita.fr>
3525
3526         * src/skeleton.h: New.
3527         * src/output.c (output_parser, output_master_parser): Remove, dead
3528         code.
3529         * src/output.h (get_lines_number, actions_output, guards_output)
3530         (token_definitions_output): Prototype them.
3531         * src/parse-skel.y: Add the license notice.
3532         Include output.h and skeleton.h.
3533         (process_skeleton): Returns void, and takes a single parameter.
3534         * src/scan-skel.l: Add the license notice.
3535         Include skeleton.h.
3536         Don't use %option yylineno: it seems that then Flex imagines
3537         REJECT has been used, and therefore it won't reallocate its
3538         buffers (which makes no other sense to me than a bug).  It results
3539         in warnings for `unused: yy_flex_realloc'.
3540
3541 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
3542
3543         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3544         (MUSCLE_INSERT_PREFIX): ...to there.
3545         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3546         (MUSCLE_INSERT_PREFIX): Move from here...
3547
3548         * src/bison.hairy: Add a section directive.  Put braces around muscle
3549         names.  This parser skeleton is still broken, but Bison should not
3550         choke on a bad muscle 'syntax'.
3551         * src/bison.simple: Add a section directive.  Put braces around muscle
3552         names.
3553
3554         * src/files.h (strsuffix, stringappend): Add declarations.
3555         (tab_extension): Add declaration.
3556         (short_base_name): Add declaration.
3557
3558         * src/files.c (strsuffix, stringappend): No longer static.  These
3559         functions are used in the skeleton parser.
3560         (tab_extension): New.
3561         (compute_base_names): Use the computations done in this function
3562         to guess if the generated parsers should have '.tab' in their
3563         names.
3564         (short_base_name): No longer static.
3565
3566         * src/output.c (output_skeleton): New.
3567         (output): Disable call to output_master_parser, and give a try to
3568         a new skeleton handling system.
3569         (guards_output, actions_output): No longer static.
3570         (token_definitions_output, get_lines_number): No longer static.
3571
3572         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3573
3574         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3575         parse-skel.y.
3576
3577         * src/parse-skel.y: New file.
3578         * src/scan-skel.l: New file.
3579
3580 2001-12-29  Akim Demaille  <akim@epita.fr>
3581
3582         %name-prefix is broken.
3583
3584         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3585         Adjust all dependencies.
3586         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3587         %name-prefix.
3588
3589         Renaming yylval but not yylloc is not consistent.  Now we do.
3590
3591         * src/bison.simple: Prefix yylloc if used.
3592         * doc/bison.texinfo (Decl Summary): Document that.
3593
3594 2001-12-29  Akim Demaille  <akim@epita.fr>
3595
3596         * doc/bison.texinfo: Promote `%long-directive' over
3597         `%long_directive'.
3598         Remove all references to fixed-output-files, yacc is enough.
3599
3600 2001-12-29  Akim Demaille  <akim@epita.fr>
3601
3602         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3603         user prologue.  These are defaults.
3604         * tests/actions.at (Mid-rule actions): Make sure the user can
3605         define YYDEBUG and YYERROR_VERBOSE.
3606
3607 2001-12-29  Akim Demaille  <akim@epita.fr>
3608
3609         * src/output.c (header_output): Don't forget to export YYLTYPE and
3610         yylloc.
3611         * tests/headers.at (export YYLTYPE): New, make sure it does.
3612         * tests/regression.at (%union and --defines, Invalid CPP headers):
3613         Move to...
3614         * tests/headers.at: here.
3615
3616 2001-12-29  Akim Demaille  <akim@epita.fr>
3617
3618         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3619
3620 2001-12-29  Akim Demaille  <akim@epita.fr>
3621
3622         * tests/actions.at (Mid-rule actions): Output on a single line
3623         instead of several.
3624
3625 2001-12-29  Akim Demaille  <akim@epita.fr>
3626
3627         * doc/bison.texinfo: Formatting changes.
3628
3629 2001-12-29  Akim Demaille  <akim@epita.fr>
3630
3631         Don't store the token defs in a muscle, just be ready to output it
3632         on command.  Now possible via `symbols'.  Fixes a memory leak.
3633
3634         * src/output.c (token_definitions_output): New.
3635         (output_parser, header_output): Use it.
3636         * src/reader.c (symbols_save): Remove.
3637
3638 2001-12-29  Akim Demaille  <akim@epita.fr>
3639
3640         * src/bison.simple: Do not provide a default for YYSTYPE and
3641         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3642         default.
3643
3644 2001-12-29  Akim Demaille  <akim@epita.fr>
3645
3646         Mid-rule actions are simply... ignored!
3647
3648         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3649         the empty-rule associated to the dummy symbol, not to the host
3650         rule.
3651         * tests/actions.at (Mid-rule actions): New.
3652
3653 2001-12-29  Akim Demaille  <akim@epita.fr>
3654
3655         Memory leak.
3656
3657         * src/reader.c (reader): Free grammar.
3658
3659 2001-12-29  Akim Demaille  <akim@epita.fr>
3660
3661         Memory leak.
3662
3663         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3664         since it allocates it for each state, although only one is needed.
3665         (allocate_storage): Do it here.
3666
3667 2001-12-29  Akim Demaille  <akim@epita.fr>
3668
3669         * src/options.h, src/options.c (create_long_option_table): Rename
3670         as...
3671         (long_option_table_new): this, with a clearer prototype.
3672         (percent_table): Remove, unused,
3673         * src/getargs.c (getargs): Adjust.
3674
3675 2001-12-29  Akim Demaille  <akim@epita.fr>
3676
3677         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3678         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3679         as states.
3680
3681 2001-12-29  Akim Demaille  <akim@epita.fr>
3682
3683         * src/lalr.c (build_relations): Rename `states' as `states1'.
3684         Sorry, I don't understand exactly what it is, no better name...
3685
3686 2001-12-29  Akim Demaille  <akim@epita.fr>
3687
3688         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3689         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3690         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3691         as rules.
3692
3693 2001-12-29  Akim Demaille  <akim@epita.fr>
3694
3695         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3696         ago.
3697
3698 2001-12-29  Akim Demaille  <akim@epita.fr>
3699
3700         * src/reader.c, src/reader.h (user_toknums): Remove.
3701         Adjust all users to use symbols[i]->user_token_number.
3702
3703 2001-12-29  Akim Demaille  <akim@epita.fr>
3704
3705         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3706         Adjust all users to use symbols[i]->prec or ->assoc.
3707
3708 2001-12-29  Akim Demaille  <akim@epita.fr>
3709
3710         * src/reader.c, src/reader.h (tags): Remove.
3711         Adjust all users to use symbols[i]->tag.
3712
3713 2001-12-29  Akim Demaille  <akim@epita.fr>
3714
3715         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3716         and rule_table.
3717         * src/reader.c (packsymbols): Fill this table.
3718         Drop sprec.
3719         * src/conflicts.c (resolve_sr_conflict): Adjust.
3720         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3721         single table.
3722         Use symbols[i]->tag instead of tags[i].
3723
3724 2001-12-29  Akim Demaille  <akim@epita.fr>
3725
3726         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3727         In addition, put a comment in there, to replace...
3728         * tests/regression.at (%union and C comments): Remove.
3729
3730 2001-12-29  Akim Demaille  <akim@epita.fr>
3731
3732         * tests/regression.at (Web2c Actions): Blindly move the actual
3733         output as expected output.  The contents *seem* right to me, but I
3734         can't pretend reading perfectly parser tables...  Nonetheless, all
3735         the other tests pass correctly, the table look OK, even though the
3736         presence of `$axiom' is to be noted: AFAICS it is useless (but
3737         harmless).
3738
3739 2001-12-29  Akim Demaille  <akim@epita.fr>
3740
3741         * src/reader.c (readgram): Don't add the rule 0 if there were no
3742         rules read.  In other words, add it _after_ having performed
3743         grammar sanity checks.
3744         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3745
3746 2001-12-29  Akim Demaille  <akim@epita.fr>
3747
3748         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3749         visible, and some states have now a different number.

3751 2001-12-29  Akim Demaille  <akim@epita.fr>
3752
3753         * src/reader.c (readgram): Bind the initial rule's lineno to that
3754         of the first rule.
3755         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3756         (Solved SR Conflicts): Adjust rule 0's line number.
3757
3758 2001-12-29  Akim Demaille  <akim@epita.fr>
3759
3760         Fix the `GAWK Grammar' failure.
3761
3762         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3763         the reductions of the first state which was mistakenly confused
3764         with the final state because precisely final_state was initialized
3765         to 0.
3766         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3767         now noticed by Bison.
3768         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3769         have a reduction on $default.
3770
3771 2001-12-29  Akim Demaille  <akim@epita.fr>
3772
3773         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3774         rule line numbers.
3775         * src/closure.c (print_closure): Likewise.
3776         * src/derives.c (print_derives): Likewise.
3777         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3778         now.
3779
3780 2001-12-29  Akim Demaille  <akim@epita.fr>
3781
3782         * src/lalr.c (lookaheads_print): New.
3783         (lalr): Call it when --trace-flag.
3784         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3785         are dumped.
3786
3787 2001-12-29  Akim Demaille  <akim@epita.fr>
3788
3789         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3790         when walking through ritem, even via rule->rhs.
3791         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3792         (useful_production, useless_nonterminals): Likewise.
3793         (reduce_grammar_tables): Likewise, plus update nritems.
3794         * src/nullable.c (set_nullable): Likewise.
3795         * src/lalr.c (build_relations): Likewise.
3796         * tests/sets.at (Nullable): Adjust.
3797         Fortunately, now, the $axiom is no longer nullable.
3798
3799 2001-12-29  Akim Demaille  <akim@epita.fr>
3800
3801         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3802         the 0-sentinel.
3803         * src/gram.c (ritem_longest_rhs): Likewise.
3804         * src/reduce.c (nonterminals_reduce): Likewise.
3805         * src/print_graph.c (print_graph): Likewise.
3806         * src/output.c (output_rule_data): Likewise.

3809 2001-12-29  Akim Demaille  <akim@epita.fr>
3810
3811         * src/output.c: Comment changes.
3812
3813 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3814
3815         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3816         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3817         Sparc, as they were causing more porting problems than the
3818         (minor) performance improvement was worth.
3819
3820         Also, catch up with 1.31's YYSTD.
3821
3822 2001-12-27  Akim Demaille  <akim@epita.fr>
3823
3824         * src/output.c (output_gram): Rely on nritems, not the
3825         0-sentinel.  See below.
3826         Use -1 as separator, not 0.
3827         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3828         Rely on -1 as separator in yyrhs, instead of 0.
3829         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3830         twice `Now at end of input', therefore there are two lines less to
3831         expect.
3832
3833 2001-12-27  Akim Demaille  <akim@epita.fr>
3834
3835         * tests/regression.at (Unresolved SR Conflicts):
3836         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3837         below.
3838
3839 2001-12-27  Akim Demaille  <akim@epita.fr>
3840
3841         * src/LR0.c (new_state): Recognize the final state by the fact it
3842         is reached by eoftoken.
3843         (insert_start_shifting_state, insert_eof_shifting_state)
3844         (insert_accepting_state, augment_automaton): Remove, since now
3845         these states are automatically computed from the initial state.
3846         (generate_states): Adjust.
3847         * src/print.c: When reporting a rule number to the user, substract
3848         1, so that the axiom rule is rule 0, and the first user rule is 1.
3849         * src/reduce.c: Likewise.
3850         * src/print_graph.c (print_core): For the time being, just as for
3851         the report, depend upon --trace-flags to dump the full set of
3852         items.
3853         * src/reader.c (readgram): Once the grammar read, insert the rule
3854         0: `$axiom: START-SYMBOL $'.
3855         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3856         number of the states has changed (the final state is no longer
3857         necessarily the last), catch up.
3858
3859 2001-12-27  Akim Demaille  <akim@epita.fr>
3860
3861         Try to make the use of the eoftoken valid.  Given that its value
3862         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3863         is used instead of > 0 where appropriate, (ii), depend upon nritems
3864         instead of the 0-sentinel.
3865
3866         * src/gram.h, src/gram.c (nritems): New.
3867         Expected to be duplication of nitems, but for the time being...
3868         * src/reader.c (packgram): Assert nritems and nitems are equal.
3869         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3870         * src/closure.c (print_closure, print_fderives): Likewise.
3871         * src/gram.c (ritem_print): Likewise.
3872         * src/print.c (print_core, print_grammar): Likewise.
3873         * src/print_graph.c: Likewise.
3874
3875 2001-12-27  Akim Demaille  <akim@epita.fr>
3876
3877         * src/main.c (main): If there are complains after grammar
3878         reductions, then output the report anyway if requested, then die.
3879         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3880         * src/reader.c (eoftoken): New.
3881         (parse_token_decl): If the token being defined has value `0', it
3882         is the eoftoken.
3883         (packsymbols): No longer hack `tags' to insert `$' by hand.
3884         Be sure to preserve the value of the eoftoken.
3885         (reader): Make sure eoftoken is defined.
3886         Initialize nsyms to 0: now eoftoken is created just like the others.
3887         * src/print.c (print_grammar): Don't special case the eof token.
3888         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3889         lie anyway, albeit pleasant.
3890         * tests/calc.at: Exercise error messages with eoftoken.
3891         Change the grammar so that empty input is invalid.
3892         Adjust expectations.
3893         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3894
3895 2001-12-27  Akim Demaille  <akim@epita.fr>
3896
3897         * configure.in: Check the protos of strchr ans strspn.
3898         Replace strchr if needed.
3899         * src/system.h: Provide the protos of strchr, strspn and memchr if
3900         missing.
3901         * lib/strchr.c: New.
3902         * src/reader.c (symbols_save): Use strchr.
3903
3904 2001-12-27  Akim Demaille  <akim@epita.fr>
3905
3906         * src/print.c, src/print_graph.c (escape): New.
3907         Use it to quote the TAGS outputs.
3908         * src/print_graph.c (print_state): Now errors are in red, and
3909         reductions in green.
3910         Prefer high to wide: output the state number on a line of its own.
3911
3912 2001-12-27  Akim Demaille  <akim@epita.fr>
3913
3914         * src/state.h, src/state.c (reductions_new): New.
3915         * src/LR0.c (set_state_table): Let all the states have a
3916         `reductions', even if reduced to 0.
3917         (save_reductions): Adjust.
3918         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
3919         * src/print.c (print_reductions, print_actions): Adjust.
3920         * src/output.c (action_row): Adjust.
3921
3922 2001-12-27  Akim Demaille  <akim@epita.fr>
3923
3924         * src/state.h, src/state.c (errs_new, errs_dup): New.
3925         * src/LR0.c (set_state_table): Let all the states have an errs,
3926         even if reduced to 0.
3927         * src/print.c (print_errs, print_reductions): Adjust.
3928         * src/output.c (output_actions, action_row): Adjust.
3929         * src/conflicts.c (resolve_sr_conflict): Adjust.
3930
3931 2001-12-27  Akim Demaille  <akim@epita.fr>
3932
3933         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3934
3935 2001-12-27  Akim Demaille  <akim@epita.fr>
3936
3937         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3938         * src/print.c: here.
3939         (lookaheadset, shiftset): New, used as additional storage by
3940         print_reductions.
3941         (print_results): Adjust.
3942         (print_shifts, print_gotos, print_errs): New, extracted from...
3943         (print_actions): here.
3944         * src/print_graph.c (print_actions): Remove dead code.
3945
3946 2001-12-27  Akim Demaille  <akim@epita.fr>
3947
3948         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3949         `$n' and `@n'.
3950
3951 2001-12-27  Akim Demaille  <akim@epita.fr>
3952
3953         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3954         (build_relations): Adjust.
3955
3956 2001-12-27  Akim Demaille  <akim@epita.fr>
3957
3958         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3959         duplication.
3960
3961 2001-12-27  Akim Demaille  <akim@epita.fr>
3962
3963         * src/reader.c (packgram): Catch nitems overflows.
3964
3965 2001-12-27  Akim Demaille  <akim@epita.fr>
3966
3967         * src/files.c, src/files.h (guard_obstack): Remove.
3968         * src/output.c (output): Adjust.
3969         * src/reader.c (parse_braces): New, factoring...
3970         (copy_action, copy_guard): these two which are renamed as...
3971         (parse_action, parse_guard): these.
3972         As a voluntary consequence, using braces around guards is now
3973         mandatory.
3974
3975 2001-12-27  Akim Demaille  <akim@epita.fr>
3976
3977         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3978         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3979         members.
3980         (symbol_list_new): Adjust.
3981         (copy_action): action_line is the first line, not the last.
3982         (copy_guard): Just as for actions, store the `action' only, not
3983         the switch/case/break flesh.
3984         Don't parse the user action that might follow the guard, let...
3985         (readgram): do it, i.e., now, there can be an action after a
3986         guard.
3987         In other words the guard is just explicitly optional.
3988         (packgram): Adjust.
3989         * src/output.c (guards_output): New.
3990         (output_parser): Call it when needed.
3991         (output): Also free the guard and attrs obstacks.
3992         * src/files.c, src/files.h (obstack_save): Remove.
3993         (output_files): Remove.
3994         As a result, if one needs the former `.act' file, using an
3995         appropriate skeleton which requires actions and guards is now
3996         required.
3997         * src/main.c (main): Adjust.
3998         * tests/semantic.at: New.
3999         * tests/regression.at: Use `input.y' as input file name.
4000         Avoid 8+3 problems by requiring input.c when the test needs the
4001         parser.
4002
4003 2001-12-27  Akim Demaille  <akim@epita.fr>
4004
4005         * src/reader.c (symbol_list_new): Be sure to initialize all the
4006         fields.
4007
4008 2001-12-27  Akim Demaille  <akim@epita.fr>
4009
4010         All the hacks using a final pseudo state are now useless.
4011
4012         * src/LR0.c (set_state_table): state_table holds exactly nstates.
4013         * src/lalr.c (nLA): New.
4014         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
4015         instead of lookaheadsp from the pseudo state (nstate + 1).
4016
4017 2001-12-27  Akim Demaille  <akim@epita.fr>
4018
4019         * src/output.c (action_row, token_actions): Use a state_t instead
4020         of a integer, and nlookaheads instead of the following state's
4021         lookaheadsp.
4022
4023 2001-12-27  Akim Demaille  <akim@epita.fr>
4024
4025         * src/conflicts.c (log_resolution, flush_shift)
4026         (resolve_sr_conflict, set_conflicts, solve_conflicts)
4027         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
4028         (conflicts_print, print_reductions): Use a state_t instead of an
4029         integer when referring to a state.
4030         As much as possible, depend upon nlookaheads, instead of the
4031         `lookaheadsp' member of the following state (since lookaheads of
4032         successive states are successive, the difference between state n + 1
4033         and n served as the number of lookaheads for state n).
4034         * src/lalr.c (add_lookback_edge): Likewise.
4035         * src/print.c (print_core, print_actions, print_state)
4036         (print_results): Likewise.
4037         * src/print_graph.c (print_core, print_actions, print_state)
4038         (print_graph): Likewise.

4041 2001-12-27  Akim Demaille  <akim@epita.fr>
4042
4043         * src/bison.hairy: Formatting/comment changes.
4044         ANSIfy.
4045         Remove `register' indications.
4046         Add plenty of `static'.
4047
4048 2001-12-27  Akim Demaille  <akim@epita.fr>
4049
4050         * src/output.c (prepare): Drop the muscle `ntbase' which
4051         duplicates ntokens.
4052         * src/bison.simple: Formatting/comment changes.
4053         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
4054         is an undocumented synonym.
4055
4056 2001-12-22  Akim Demaille  <akim@epita.fr>
4057
4058         * src/output.c (output_table_data): Change the prototype to use
4059         `int' for array ranges: some invocations do pass an int, not a
4060         short.
4061         Reported by Wayne Green.

4066         Reported by Mike Castle.
4067
4068         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
4069         * tests/regression.at (Web2c): Rename as...
4070         (Web2c Report): this.
4071         (Web2c Actions): New.
4072
4073 2001-12-22  Akim Demaille  <akim@epita.fr>
4074
4075         Reductions in web2c.y are improperly reported.
4076         Reported by Mike Castle.
4077
4078         * src/conflicts.c (print_reductions): Fix.
4079         * tests/regression.at (Web2c): New.
4080
4081 2001-12-18  Akim Demaille  <akim@epita.fr>
4082
4083         Some host fail on `assert (!"foo")', which expands to
4084         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
4085         Reported by Nelson Beebee.
4086
4087         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
4088         `#define it_succeeded 0' and `assert (it_succeeded)'.
4089
4090 2001-12-17  Marc Autret  <autret_m@epita.fr>
4091
4092         * src/bison.simple: Don't hard code the skeleton line and filename.
4093         * src/output.c (output_parser): Rename 'line' as 'output_line'.
4094         New line counter 'skeleton_line' (skeleton-line muscle).
4095
4096 2001-12-17  Paul Eggert  <eggert@twinsun.com>
4097
4098         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
4099         YYDEBUG must be defined to a nonzero value.
4100
4101         * src/bison.simple (yytname): Do not assume that the user defines
4102         YYDEBUG to a properly parenthesized expression.
4103
4104 2001-12-17  Akim Demaille  <akim@epita.fr>
4105
4106         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
4107         nlookaheads is a new member.
4108         Adjust all users.
4109         * src/lalr.h (nlookaheads): Remove this orphan declaration.
4110         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
4111         state.
4112
4113 2001-12-17  Akim Demaille  <akim@epita.fr>
4114
4115         * src/files.h, src/files.c (open_files, close_files): Remove.
4116         * src/main.c (main): Don't open/close files, nor invoke lex_free,
4117         let...
4118         * src/reader.c (reader): Do it.
4119
4120 2001-12-17  Akim Demaille  <akim@epita.fr>
4121
4122         * src/conflicts.c (print_reductions): Formatting changes.
4123
4124 2001-12-17  Akim Demaille  <akim@epita.fr>
4125
4126         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
4127         (flush_reduce): New.
4128         (resolve_sr_conflict): Adjust.
4129
4130 2001-12-17  Akim Demaille  <akim@epita.fr>
4131
4132         * src/output.c (output_obstack): Be static and rename as...
4133         (format_obstack): this, to avoid any confusion with files.c's
4134         output_obstack.
4135         * src/reader.h (muscle_obstack): Move to...
4136         * src/output.h: here, since it's defined in output.c.
4137
4138 2001-12-17  Akim Demaille  <akim@epita.fr>
4139
4140         * src/output.c (action_row, save_column, default_goto)
4141         (sort_actions, matching_state, pack_vector): Better variable
4142         locality.
4143
4144 2001-12-17  Akim Demaille  <akim@epita.fr>
4145
4146         * src/output.c: Various formatting changes.
4147
4148 2001-12-17  Akim Demaille  <akim@epita.fr>
4149
4150         * src/files.c (output_files): Free the output_obstack.
4151         * src/main.c (main): Call print and print_graph conditionally.
4152         * src/print.c (print): Work unconditionally.
4153         * src/print_graph.c (print_graph): Work unconditionally.
4154         * src/conflicts.c (log_resolution): Output only if verbose_flag.
4155
4156 2001-12-16  Marc Autret  <autret_m@epita.fr>
4157
4158         * src/output.c (actions_output): Fix. When we use %no-lines,
4159         there is one less line per action.
4160
4161 2001-12-16  Marc Autret  <autret_m@epita.fr>
4162
4163         * src/bison.simple: Remove a useless #line directive.
4164         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4165         * src/output.c (get_lines_number): New.
4166         (output_parser): Adjust, now takes care about the lines of a
4167         output muscles.
4168         Fix line numbering.
4169         (actions_output): Computes the number of lines taken by actions.
4170         (output_master_parser): Insert new skeleton which is the name of
4171         the output parser file name.
4172
4173 2001-12-15  Marc Autret  <autret_m@epita.fr>
4174
4175         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
4176
4177 2001-12-15  Marc Autret  <autret_m@epita.fr>
4178
4179         * src/output.c (output_gram): Keep track of the hairy one.
4180
4181 2001-12-15  Akim Demaille  <akim@epita.fr>
4182
4183         Make `make distcheck' work.
4184
4185         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4186         system.h which uses libgettext.h.
4187
4188 2001-12-15  Akim Demaille  <akim@epita.fr>
4189
4190         * src/nullable.c (set_nullable): Useless rules must be skipped,
4191         otherwise, since we range over their symbols, we might look at a
4192         nonterminal which no longer ``exists'', i.e., it is not counted in
4193         `nvars', hence we overflow our arrays.
4194
4195 2001-12-15  Akim Demaille  <akim@epita.fr>
4196
4197         The header can also be produced directly, without any obstack!
4198         Yahoo!
4199
4200         * src/files.c, src/files.h (defines_obstack): Remove.
4201         (compute_header_macro): Global.
4202         (defines_obstack_save): Remove.
4203         * src/reader.c (parse_union_decl): No longer output to
4204         defines_obstack: its content can be found in the `stype' muscle
4205         anyway.
4206         (output_token_translations): Merge into...
4207         (symbols_output): this.
4208         Rename as...
4209         (symbols_save): this.
4210         (reader): Adjust.
4211         * src/output.c (header_output): New.
4212         (output): Call it.
4213
4214 2001-12-15  Akim Demaille  <akim@epita.fr>
4215
4216         * src/reader.c (parse_union_decl): Instead of handling two obstack
4217         simultaneously, use one to define the `stype' muscle, and use the
4218         value of the latter to fill defines_obstack.
4219         (copy_comment): Remove.
4220         (copy_comment2): Work for a single obstack.
4221         Rename as...
4222         (copy_comment): this.
4223
4224 2001-12-15  Akim Demaille  <akim@epita.fr>
4225
4226         * src/lex.c, src/lex.h (xgetc): No longer static.
4227         * src/reader.c (parse_union_decl): Revamp.
4228
4229 2001-12-15  Akim Demaille  <akim@epita.fr>
4230
4231         Still making progress in separating Bison into (i) input, (ii)
4232         process, (iii) output: now we can directly output the parser file
4233         without using table_obstack at all.
4234
4235         * src/files.c, src/files.h (table_obstack): Bye bye.
4236         (parser_file_name): New.
4237         * src/files.c (compute_output_file_names): Compute it.
4238         * src/output.c (actions_output, output_parser)
4239         (output_master_parser): To a file instead of an obstack.
4240
4241 2001-12-15  Akim Demaille  <akim@epita.fr>
4242
4243         Attach actions to rules, instead of pre-outputting them to
4244         actions_obstack.
4245
4246         * src/gram.h (rule_t): action and action_line are new members.
4247         * src/reader.c (symbol_list): Likewise.
4248         (copy_action): Save the actions within the rule.
4249         (packgram): Save them in rule_table.
4250         * src/output.c (actions_output): New.
4251         (output_parser): Use it on `%%actions'.
4252         (output_rule_data): Don't free rule_table.
4253         (output): Do it.
4254         (prepare): Don't save the `action' muscle.
4255         * src/bison.simple: s/%%action/%%actions/.
4256
4257 2001-12-15  Akim Demaille  <akim@epita.fr>
4258
4259         * src/reader.c (copy_action): When --yacc, don't append a `;'
4260         to the user action: let it fail if lacking.
4261         Suggested by Arnold Robbins and Tom Tromey.
4262
4263 2001-12-14  Akim Demaille  <akim@epita.fr>
4264
4265         * src/lex.c (literalchar): Simply return the char you decoded, non
4266         longer mess around with obstacks and int pointers.
4267         Adjust all callers.
4268
4269 2001-12-14  Akim Demaille  <akim@epita.fr>
4270
4271         * src/lex.c (literalchar): Don't escape the special characters,
4272         just decode them, and keep them as char (before, eol was output as
4273         the 2 char string `\n' etc.).
4274         * src/output.c (output_rule_data): Use quotearg to output the
4275         token strings.
4276
4277 2001-12-13  Paul Eggert  <eggert@twinsun.com>
4278
4279         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4280         Do not infringe on the global user namespace when using C++.
4281         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4282         All uses of `fprintf' and `stderr' changed.
4283
4284         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4285
4286 2001-12-13  Akim Demaille  <akim@epita.fr>
4287
4288         The computation of nullable is broken: it doesn't handle empty
4289         RHS's properly.
4290
4291         * tests/torture.at (GNU AWK Grammar): New.
4292         * tests/sets.at (Nullable): New.
4293         * src/nullable.c (set_nullable): Instead of blindly looping over
4294         `ritems', loop over the rules, and then over their rhs's.
4295
4296         Work around Autotest bugs.
4297
4298         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4299         frame, because Autotest understand lines starting with a `+' as
4300         traces from the shell.  Then, they are not processed properly.
4301         Admittedly an Autotest bug, but we don't have time to wait for
4302         Autotest to catch up.
4303         * tests/regression.at (Broken Closure): Adjust to the new table
4304         frames.
4305         Move to...
4306         * tests/sets.at: here.
4307
4308 2001-12-13  Akim Demaille  <akim@epita.fr>
4309
4310         * src/closure.c (closure): Use nrules instead of playing tricks
4311         with BITS_PER_WORD.
4312
4313 2001-12-13  Akim Demaille  <akim@epita.fr>
4314
4315         * src/print.c (print_actions): Output the handling of `$' as the
4316         traces do: shifting the token EOF.  Before EOF was treated as a
4317         nonterminal.
4318         * tests/regression.at: Adjust some tests.
4319         * src/print_graph.c (print_core): Complete the set of items via
4320         closure.  The next-to-final and final states are still unsatisfying,
4321         but that's to be addressed elsewhere.
4322         No longer output the rule numbers, but do output the state number.
4323         A single loop for the shifts + gotos is enough, but picked a
4324         distinct color for each.
4325         (print_graph): Initialize and finalize closure.
4326
4327 2001-12-13  Akim Demaille  <akim@epita.fr>
4328
4329         * src/reader.c (readgram): Remove dead code, an strip useless
4330         braces.
4331         (get_type): Remove, unused.
4332
4333 2001-12-12  Akim Demaille  <akim@epita.fr>
4334
4335         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4336         on that of lib/error.c.
4337
4338 2001-12-12  Akim Demaille  <akim@epita.fr>
4339
4340         Some hosts don't like `/' in includes.
4341
4342         * src/system.h: Include libgettext.h without qualifying the path.
4343         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4344         $(top_srcdir).
4345
4346 2001-12-11  Marc Autret  <autret_m@epita.fr>
4347
4348         * src/output.c (output_parser): Remove useless muscle.
4349
4350 2001-12-11  Marc Autret  <autret_m@epita.fr>
4351
4352         * src/bison.simple: Remove #line just before %%epilogue. It
4353         is now handled in ...
4354         * src/reader.c (read_additionnal_code): Add the output of a
4355         #line for the epilogue.
4356
4357 2001-12-10  Marc Autret  <autret_m@epita.fr>
4358
4359         * src/reader.c (copy_definition): Re-use CPP-outed code which
4360         replace precedent remove.
4361         * src/bison.simple: Remove #line before %%prologue because
4362         %%input-line is wrong at this time.
4363
4364 2001-12-10  Marc Autret  <autret_m@epita.fr>
4365
4366         * src/reader.c (symbols_output): Clean up.
4367         * src/output.c (output_gram, output): Clean up.
4368
4369 2001-12-10  Akim Demaille  <akim@epita.fr>
4370
4371         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
4372         * src/LR0.c (set_state_table): here.
4373         * src/lalr.c (lalr): Call it.
4374
4375 2001-12-10  Akim Demaille  <akim@epita.fr>
4376
4377         * src/state.h (shifts): Remove the `number' member: shifts are
4378         attached to state, hence no longer need to be labelled with a
4379         state number.
4380
4381 2001-12-10  Akim Demaille  <akim@epita.fr>
4382
4383         Now that states have a complete set of members, the linked list of
4384         shifts is useless: just fill directly the state's shifts member.
4385
4386         * src/state.h (shifts): Remove the `next' member.
4387         * src/LR0.c (first_state, last_state): Remove.
4388         Adjust the callers.
4389         (augment_automaton): Don't look for the shifts that must be added
4390         a shift on EOF: it is those of the state we looked for!  But now,
4391         since shifts are attached, it is no longer needed to looking
4392         merely by its id: its number.
4393
4394 2001-12-10  Akim Demaille  <akim@epita.fr>
4395
4396         * src/LR0.c (augment_automaton): Better variable locality.
4397         Remove an impossible branch: if there is a state corresponding to
4398         the start symbol being shifted, then there is shift for the start
4399         symbol from the initial state.
4400
4401 2001-12-10  Akim Demaille  <akim@epita.fr>
4402
4403         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4404         only when appropriate: when insert_start_shifting_state' is not
4405         invoked.
4406         * tests/regression.at (Rule Line Numbers): Adjust.
4407
4408 2001-12-10  Akim Demaille  <akim@epita.fr>
4409
4410         * src/LR0.c (augment_automaton): Now that all states have shifts,
4411         merge the two cases addition shifts to the initial state.
4412
4413 2001-12-10  Akim Demaille  <akim@epita.fr>
4414
4415         * src/lalr.c (set_state_table): Move to...
4416         * src/LR0.c: here.
4417         * src/lalr.c (lalr): Don't call it...
4418         * src/LR0.c (generate_states): do it.
4419         * src/LR0.h (first_state): Remove, only the table is used.
4420
4421 2001-12-10  Akim Demaille  <akim@epita.fr>
4422
4423         * src/LR0.h (first_shift, first_reduction): Remove.
4424         * src/lalr.c: Don't use first_shift: find shifts through the
4425         states.
4426
4427 2001-12-10  Akim Demaille  <akim@epita.fr>
4428
4429         * src/LR0.c: Attach shifts to states as soon as they are
4430         computed.
4431         * src/lalr.c (set_state_table): Instead of assigning shifts to
4432         state, just assert that the mapping was properly done.
4433
4434 2001-12-10  Akim Demaille  <akim@epita.fr>
4435
4436         * src/LR0.c (insert_start_shift): Rename as...
4437         (insert_start_shifting_state): this.
4438         (insert_eof_shifting_state, insert_accepting_state): New.
4439         (augment_automaton): Adjust.
4440         Better locality of the variables.
4441         When looking if the start_symbol is shifted from the initial
4442         state, using `while (... symbol != start_symbol ...)' sounds
4443         better than `while (... symbol < start_symbol ...)': If fail
4444         to see how the order between symbols could be relevant!
4445
4446 2001-12-10  Akim Demaille  <akim@epita.fr>
4447
4448         * src/getargs.h: Don't declare `spec_name_prefix' and
4449         `spec_file_prefix', declared by src/files.h.
4450         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4451         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4452         * src/output.c (prepare): Adjust.
4453         * src/reader.c (symbols_output): Likewise.
4454         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4455
4456 2001-12-10  Akim Demaille  <akim@epita.fr>
4457
4458         * src/muscle_tab.c (muscle_init): NULL is a better default than
4459         `"0"'.
4460
4461 2001-12-10  Akim Demaille  <akim@epita.fr>
4462
4463         * src/reader.c (reader): Calling symbols_output once is enough.
4464
4465 2001-12-10  Akim Demaille  <akim@epita.fr>
4466
4467         Now that states have a complete set of members, the linked list of
4468         reductions is useless: just fill directly the state's reductions
4469         member.
4470
4471         * src/state.h (struct reductions): Remove member `number' and
4472         `next'.
4473         * src/LR0.c (first_reduction, last_reduction): Remove.
4474         (save_reductions): Don't link the new reductions, store them in
4475         this_state.
4476         * src/lalr.c (set_state_table): No need to attach reductions to
4477         states, it's already done.
4478         * src/output.c (output_actions): No longer free the shifts, then
4479         the reductions, then the states: free all the states and their
4480         members.
4481
4482 2001-12-10  Akim Demaille  <akim@epita.fr>
4483
4484         * src/options.c (OPTN, DRTV, BOTH): New.
4485         (option_table): Use them.
4486
4487         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4488         the job of system.h.
4489         * src/options.c: Don't include stdio.h and xalloc.h for the same
4490         reasons.
4491
4492 2001-12-10  Akim Demaille  <akim@epita.fr>
4493
4494         * src/output.c (output, prepare): Make sure the values of the
4495         muscles `action' and `prologue' are 0-terminated.
4496
4497 2001-12-10  Akim Demaille  <akim@epita.fr>
4498
4499         Clean up GCC warnings.
4500
4501         * src/reader.c (copy_action): `buf' is not used.
4502         (parse_skel_decl): Be static.
4503         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4504         * src/options.h (create_long_option_table): Have a real prototype.
4505         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4506         (hash_delete_at): Return const void *.
4507         Adjust casts to preserve the const.
4508
4509 2001-12-10  Akim Demaille  <akim@epita.fr>
4510
4511         * configure.in: Require 2.52g.
4512         M4 is not needed, but AUTOM4TE is.
4513         * m4/m4.m4: Remove.
4514         * tests/Makefile.am: Adjust.
4515
4516 2001-12-10  Akim Demaille  <akim@epita.fr>
4517
4518         One structure for states is enough, even though theoretically
4519         there are LR(0) states and LALR(1) states.
4520
4521         * src/lalr.h (state_t): Remove.
4522         (state_table): Be state_t **, not state_t *.
4523         * src/state.h (core, CORE_ALLOC): Rename as...
4524         (state_t, STATE_ALLOC): this.
4525         Add the LALR(1) members: shifts, reductions, errs.
4526         * src/LR0.c (state_table): Rename as...
4527         (state_hash): this, to avoid name clashes with the global
4528         `state_table'.
4529         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4530         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

4534         Bison dumps core on bash.y.
4535         Reported by Pascal Bart.
4536
4537         * src/warshall.c (bitmatrix_print): New.
4538         (TC): Use it.
4539         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4540         j must be the outer loop.
4541         * tests/regression.at (Broken Closure): New.
4542
4543 2001-12-05  Akim Demaille  <akim@epita.fr>
4544
4545         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4546         its argument.
4547         Reported by Peter Hámorský.
4548
4549 2001-12-05  Akim Demaille  <akim@epita.fr>
4550
4551         * src/conflicts.c (err_table): Remove.
4552         (resolve_sr_conflict): Adjust.
4553         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4554         Rename as...
4555         (state_t.reductions, state_t.shifts): this.
4556
4557 2001-12-05  Akim Demaille  <akim@epita.fr>
4558
4559         * src/reduce.c (reduce_grammar_tables): No longer disable the
4560         removal of useless rules via CPP but via `if (0)', so that the
4561         compiler still check the code is valid.
4562         For instance, it should have noticed `rline' no longer exists: use
4563         the `line' member of rule_t.
4564         * src/gram.c (dummy, rline): Remove, unused.
4565
4566 2001-12-05  Akim Demaille  <akim@epita.fr>
4567
4568         * src/output.c (pack_vector): Use assert, not berror.
4569         * src/main.c (berror): Remove, unused.
4570
4571 2001-12-05  Akim Demaille  <akim@epita.fr>
4572
4573         New experimental feature: if --verbose --trace output all the
4574         items of a state, not only its kernel.
4575
4576         * src/print.c (print_core): If `trace_flag', then invoke closure
4577         before outputting the items of the state (print_core is no longer
4578         a correct name them).
4579         (print_results): Invoke new_closure/free_closure if needed.
4580
4581 2001-12-05  Akim Demaille  <akim@epita.fr>
4582
4583         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4584         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4585         (nitemset): for consistency with the rest of the project.
4586
4587 2001-12-05  Akim Demaille  <akim@epita.fr>
4588
4589         * src/closure.c (print_closure): Improve.
4590         (closure): Use it for printing input and output.
4591
4592 2001-12-05  Akim Demaille  <akim@epita.fr>
4593
4594         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4595         indexed by nonterminals.
4596
4597 2001-12-05  Akim Demaille  <akim@epita.fr>
4598
4599         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4600         what it was!).
4601         * src/warshall.h: Remove accidental duplication of the content.
4602
4603 2001-12-05  Akim Demaille  <akim@epita.fr>
4604
4605         * src/closure.c (set_fderives): De-obfuscate.
4606

4614
4615 2001-12-05  Akim Demaille  <akim@epita.fr>
4616
4617         * src/output.c (action_row): De-obfuscate
4618         using the good o' techniques: arrays not pointers, variable
4619         locality, BITISSET, RESETBIT etc.
4620
4621 2001-12-05  Akim Demaille  <akim@epita.fr>
4622
4623         Pessimize the code to simplify it: from now on, all the states
4624         have a valid SHIFTS, which NSHIFTS is possibly 0.
4625
4626         * src/LR0.c (shifts_new): Be global and move to..
4627         * src/state.c, src/state.h: here.
4628         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4629         * src/print_graph: Adjust.
4630
4631 2001-12-05  Akim Demaille  <akim@epita.fr>
4632
4633         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4634         * src/conflicts.c: Use it.
4635         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4636         incorrectly ``simplified''.
4637
4638 2001-12-05  Akim Demaille  <akim@epita.fr>
4639
4640         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4641         using the good o' techniques: arrays not pointers, variable
4642         locality, BITISSET, RESETBIT etc.
4643
4644 2001-12-05  Akim Demaille  <akim@epita.fr>
4645
4646         * src/state.h (SHIFT_SYMBOL): New.
4647         * src/conflicts.c: Use it to deobfuscate.
4648
4649 2001-12-05  Akim Demaille  <akim@epita.fr>
4650
4651         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4652         (print_reductions): De-obfuscate using the good o' techniques:
4653         arrays not pointers, variable locality, BITISSET.
4654
4655 2001-12-05  Akim Demaille  <akim@epita.fr>
4656
4657         * src/conflicts.c (print_reductions): Arrays, not pointers.
4658         Use BITISSET.
4659
4660 2001-12-05  Akim Demaille  <akim@epita.fr>
4661
4662         * src/conflicts.c (print_reductions): Pessimize, but clarify.

4665
4666         * src/conflicts.c (print_reductions): Improve variable locality.

4677
4678         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

4680
4681 2001-12-05  Akim Demaille  <akim@epita.fr>
4682
4683         * src/LR0.c (augment_automaton): Formatting changes.
4684         Better variable locality.
4685
4686 2001-12-05  Akim Demaille  <akim@epita.fr>
4687
4688         * src/lalr.c (matrix_print): New.
4689         (transpose): Use it.
4690         Use arrays instead of pointers.
4691
4692 2001-12-05  Akim Demaille  <akim@epita.fr>
4693
4694         * src/lalr.c (maxrhs): Move to...
4695         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4696         * src/lalr.c (build_relations): Adjust.
4697
4698 2001-12-05  Akim Demaille  <akim@epita.fr>
4699
4700         * src/lalr.c (transpose): Free the memory allocated to the
4701         argument, as it is replaced by the results by the unique caller.
4702         (build_relations): Merely invoke transpose: it handles the memory
4703         deallocation.
4704         Improve variable locality.
4705         Avoid variables used as mere abbreviations.
4706         (compute_lookaheads): Use arrays instead of pointers.
4707
4708 2001-12-05  Akim Demaille  <akim@epita.fr>
4709
4710         * src/lalr.c (initialize_F): Improve variable locality.
4711         Avoid variables used as mere abbreviations.
4712
4713 2001-12-05  Akim Demaille  <akim@epita.fr>
4714
4715         * src/derives.c (print_derives): Display the ruleno.
4716         * src/lalr.c (initialize_F, transpose): Better variable locality
4717         to improve readability.
4718         Avoid variables used as mere abbreviations.
4719
4720 2001-12-05  Akim Demaille  <akim@epita.fr>
4721
4722         * src/lalr.c (traverse): Use arrays instead of pointers.
4723
4724 2001-12-05  Akim Demaille  <akim@epita.fr>
4725
4726         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4727         the handling of squeue.
4728         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4729
4730 2001-12-05  Akim Demaille  <akim@epita.fr>
4731
4732         Because useless nonterminals are now kept alive (instead of being
4733         `destroyed'), we now sometimes examine them, and store information
4734         related to them.  Hence we need to know their number, and adjust
4735         memory allocations.
4736
4737         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4738         static.
4739         * src/LR0.c (allocate_itemsets): The memory allocated to
4740         `symbol_count' was used for two different purpose: once to count
4741         the number of occurrences of each symbol, and later reassigned to
4742         `shift_symbol', containing the symbol that can be shifted from a
4743         given state.
4744         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4745         only, and...
4746         (new_itemsets): Allocate `shift_symbol' here.
4747         (allocate_itemsets): symbol_count includes useless nonterminals.
4748         Make room for them.
4749         (free_storage): Use `free', not `XFREE', for pointers that cannot
4750         be null.
4751
4752 2001-12-05  Akim Demaille  <akim@epita.fr>
4753
4754         * src/nullable.c (set_nullable): Deobfuscate the handling of
4755         ritem.
4756         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4757
4758 2001-12-05  Akim Demaille  <akim@epita.fr>
4759
4760         * src/gram.c, src/gram.h (ritem_print): New.
4761         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4762         (This useless function was defined only to work around VMS linkers
4763         that can't handle compilation units with variables only).
4764         * src/reduce.c (dump_grammar): Use it to trace the construction of
4765         ritem.
4766
4767 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4768
4769         * src/bison.simple (union yyalloc): Change member names
4770         to be the same as the stack names.
4771         (yyparse): yyptr is now union yyalloc *, not char *.
4772         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4773         and may generate better code on some machines.
4774         (yystpcpy): Use prototype if __STDC__ is defined, not just
4775         if __cplusplus is defined.
4776
4777 2001-11-30  Akim Demaille  <akim@epita.fr>
4778
4779         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4780         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4781         Gettext doesn't compile cleanly, and dies with -Werror.
4782         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4783         Include WARNING_CFLAGS here.
4784         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4785         before being defined.
4786
4787 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4788
4789         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4790         First arg is int, not unsigned.
4791         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4792         (SIZE_MAX, UINT_MAX): New macros.
4793         (quotearg_n_options): Abort if N is negative.
4794         Avoid overflow check on hosts where size_t is 64 bits and int
4795         is 32 bits, as overflow is impossible there.
4796         Fix off-by-one typo that caused unnecessary reallocation.

4803         and their effect on the user name space.
4804
4805         * src/bison.simple:
4806         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4807         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4808         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4809
4810         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4811         on user names when possible.
4812
4813         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.

4832         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4833         and YYSTACK_FREE instead of malloc and free.

4889         (union yyalloc): New type.
4890         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4891         an arbitrary restriction on hosts where size_t is wider than int.
4892
4893         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4894         a parser stack overflow.  Allocate just one block of memory for all
4895         three stacks, instead of allocating three blocks; this typically is
4896         faster and reduces fragmentation.
4897
4898         Do not limit the number of items in the stack to a value that fits
4899         in 'int', as this is an arbitrary limit on hosts with 64-bit
4900         size_t and 32-bit int.

4961
4962         * src/closure.c (closure): No longer optimize the special case
4963         where all the bits of `ruleset[r]' are set to 0, to make the code

5198         * src/derives.c: Likewise.
5199         * src/reduce.c: (inaccessable_symbols): Using if is better style

5228
5229         * src/vcg.c: You do the output, so you are responsible of the
5230         handling of VCG syntax, in particular: use quotearg.

5232         (print_actions): Don't output the actions as part of the nodes,

5327         * tests/calc.at, tests/output.at, tests/regression.at,
5328         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
5329         now the tests are run in private dirs, therefore AC_CLEANUP and
5330         family can be simplified to 0-ary.
5331         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
5332         use abs. path to find config.h.
5333         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
5334         stderr, there can be way too much random noise.

5352         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
5353         Revert a previous patch:  these are really const.

5357         arg_offset.
5358         arg is const.

5360         token_buffer not to change.

5456         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
5457         with yyltype/YYLTYPE.  This allows inclusion of the generated

6279
6280         * src/bison.simple (yyparse): Don't take the address of an

6290         completely wrong.

6329         bound to true.
6330         (read_declarations): Add case for macro definition.
6331         (copy_identifier): New.
6332         (parse_macro_decl): Read macro identifiers using copy_identifier

6367         with something new. Skeletons are now processed character by character
6368         rather than line by line, and Bison looks for '%%' macros. This is the
6369         first step in making Bison's output process (a lot) more flexible.
6370         (output_parser): Use the macro table.

6698
6699         * src/reader.c (gensym): `gensym_count' is your own.
6700         Use a static buf to create the symbol name, as token_buffer is no
6701         longer a buffer.
6702
6703 2001-02-08  Akim Demaille  <akim@epita.fr>
6704
6705         * src/conflicts.c (conflict_report): Be sure not to append to res
6706         between two calls, which could happen if both first sprintf were

6712         New, from fileutils 4.0.37.
6713         * configure.in: Require Autoconf 2.49c.  I took some time before
6714         making this decision.  This is the only way out for portability
6715         issues in Bison, it would mean way too much duplicate effort to
6716         import in Bison features implemented in 2.49c since 2.13.
6717         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

6727         the obstacks.
6728
6729         * src/lex.c (token_obstack): New.
6730         (init_lex): Initialize it.  No longer call...
6731         (grow_token_buffer): this.  Remove it.
6732         Adjust all the places which used it to use the obstack.
6733

6735
6736         * src/lex.h: Rename all the tokens:
6737         s/\bENDFILE\b/tok_eof/g;
6738         s/\bIDENTIFIER\b/tok_identifier/g;
6739         etc.
6740         Let them be enums, not #define, to ease debugging.
6741         Adjust all the code.
6742
6743 2001-01-18  Akim Demaille  <akim@epita.fr>
6744
6745         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
6746         * src/lex.c (maxtoken, grow_token_buffer): Static.
6747
6748 2001-01-18  Akim Demaille  <akim@epita.fr>
6749
6750         Since we now use obstacks, more % directives can be enabled.
6751
6752         * src/lex.c (percent_table): Also accept `%yacc',
6753         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
6754         `%debug'.
6755         Handle the actions for `%semantic_parser' and `%pure_parser' here,
6756         instead of returning a token.
6757         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
6758         * src/reader.c (read_declarations): Adjust.
6759         * src/files.c (open_files): Don't call `compute_base_names', don't
6760         compute `attrsfile' since they depend upon data which might be
6761         *in* the input file now.
6762         (output_files): Do it here.
6763         * src/output.c (output_headers): Document the fact that this patch
6764         introduces a guaranteed SEGV for semantic parsers.
6765         * doc/bison.texinfo: Document them.
6766         * tests/suite.at: Exercise these %options.
6767
6768 2000-12-20  Akim Demaille  <akim@epita.fr>
6769
6770         Also handle the output file (--verbose) with obstacks.
6771
6772         * files.c (foutput): Remove.
6773         (output_obstack): New.
6774         Adjust all dependencies.

6776         * src/system.h (obstack_grow_string): Rename as...
6777         (obstack_sgrow): this.  Be ready to work with non literals.

6782         * src/files.c (open_files): Fix the computation of short_base_name
6783         in the case of `-o foo.tab.c'.
6784
6785 2000-12-20  Akim Demaille  <akim@epita.fr>
6786
6787         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

6789         FILE * parameters.
6790
6791 2000-12-20  Akim Demaille  <akim@epita.fr>
6792
6793         * src/files.c (open_files): Actually the `.output' file is based
6794         on the short_base_name, not base_name.
6795         * tests/suite.at (Checking output file names): Adjust.
6796
6797 2000-12-20  Akim Demaille  <akim@epita.fr>
6798
6799         * src/bison.s1: Remove, we now use directly...
6800         * src/bison.simple: this.
6801         * src/Makefile.am: Use pkgdata instead of data.
6802

6816         (output_files): Adjust.
6817         (base_name, short_base_name): Be global.
6818         Adjust dependencies.
6819
6820 2000-12-19  Akim Demaille  <akim@epita.fr>
6821
6822         * src/files.c (strsuffix): New.
6823         (stringappend): Be just like strcat but allocate.
6824         (base_names): Eve out from open_files.
6825         Try to simplify the rather hairy computation of base_name and
6826         short_base_name.
6827         (open_files): Use it.
6828         * tests/suite.at (Checking output file names): New test.

6837         * src/bison.hairy: Likewise.
6838
6839 2000-12-19  Akim Demaille  <akim@epita.fr>
6840
6841         * src/output.c (output_parser): Compute the `#line' lines when
6842         there are.
6843         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
6844         Suggested by Hans Aberg.
6845
6846 2000-12-19  Akim Demaille  <akim@epita.fr>
6847
6848         Let the handling of the skeleton files be local to the procedures
6849         that use it.
6850
6851         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

6867
6868         * src/files.c (open_files): Yipee!  We no longer need all the code
6869         looking for `/tmp' since we have no tmp file.
6870
6871 2000-12-19  Akim Demaille  <akim@epita.fr>
6872

6886
6887         * src/reader.c (copy_definition, parse_union_decl, copy_action)
6888         (copy_guard): Quote the file names.
6889         Reported by Laurent Mascherpa.

6899
6900         * lib/obstack.h: Formatting changes.
6901         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6902         prevents type checking.
6903         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6904         cast the value to (void *): assigning a `foo *' to a `void *'
6905         variable is valid.
6906         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
6907         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

7094         When a literal string is used to define two different tokens,
7095         `bison -v' segfaults.
7096         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
7097
7098         * tests/regression.m4: New file.
7099         Include the core of the sample provided by Piotr Gackiewicz.

7101         properly.

7104
7105         * src/reader.c (parse_expect_decl): Keep `count' within the size
7106         of `buffer'.
7107         From Neil Booth.
7108
7109 2000-10-02  Paul Eggert  <eggert@twinsun.com>
7110
7111         * bison.s1 (yyparse): Assign the default value
7112         unconditionally, to avoid a GCC warning and make the parser a
7113         tad smaller.
7114
7115 2000-10-02  Akim Demaille  <akim@epita.fr>
7116
7117         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
7118         options.

7120 2000-10-02  Akim Demaille  <akim@epita.fr>
7121
7122         * src/derives.c, src/print.c, src/reduce.c: To ease the
7123         translation, move some `\n' out of the translated strings.
7124
7125 2000-10-02  Akim Demaille  <akim@epita.fr>
7126
7127         The location tracking mechanism is precious for parse error
7128         messages.  Nevertheless, it is enabled only when `@n' is used in
7129         the grammar, which is a different issue (you can use it in error
7130         message, but not in the grammar per se).  Therefore, there should
7131         be another means to enable it.
7132
7133         * src/getargs.c (getargs): Support `--locations'.
7134         (usage): Report it.
7135         * src/getargs.h (locationsflag): Export it.
7136         * src/lex.c (percent_table): Support `%locations'.
7137         * src/reader.c (yylsp_needed): Remove this variable, now replaced
7138         with `locationsflag'.
7139         * doc/bison.texinfo: Document `--locations' and `%locations'.
7140         Sort the options.
7141         * tests/calc.m4: Test it.
7142
7143         For regularity of the names, replace each
7144         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
7145         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
7146         In addition replace each `flag' with `_flag'.
7147
7148 2000-10-02  Akim Demaille  <akim@epita.fr>
7149
7150         Also test parse error messages, including with YYERROR_VERBOSE.
7151
7152         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7153         associative).
7154         Use it to check the computations.
7155         Use it to check `nonassoc' is honored.
7156         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7157         `--yyerror-verbose'.
7158         (_AT_CHECK_CALC): Adjust to this option.
7159         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7160
7161 2000-10-02  Akim Demaille  <akim@epita.fr>
7162
7163         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
7164         the latter demonstrates a flaw in the handling of non debugging
7165         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7166         was used in order to simplify:
7167
7168         #if YYDEBUG
7169         if (yydebug)
7170         {
7171         ...
7172         }
7173         #endif
7174
7175         into
7176
7177         if (yydebug)
7178         {
7179         ...
7180         }
7181
7182         unfortunately this leads to a CPP conflict when
7183         `--name-prefix=foo' is used since it produces `#define yydebug
7184         foodebug'.
7185
7186         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7187         (YYDPRINTF): New macro.
7188         Spread its use.
7189         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7190         the bison options.
7191         Also test `--verbose', `--defines' and `--name-prefix'.
7192
7193 2000-10-02  Akim Demaille  <akim@epita.fr>
7194
7195         Improve the readability of the produced parsers.
7196
7197         * src/bison.s1: Formatting changes.
7198         Improve the comment related to the `$' mark.
7199         (yydefault): Don't fall through to `yyresume': `goto' there.
7200         * src/output.c (output_parser): When the `$' is met, skip the end
7201         of its line.
7202         New variable, `number_of_dollar_signs', to check there's exactly
7203         one `$' in the parser skeleton.
7204
7205 2000-10-02  Akim Demaille  <akim@epita.fr>
7206
7207         * lib/xstrdup.c: New file, from the fileutils.
7208         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7209         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7210         instead of strlen + xmalloc + strcpy.
7211         * src/symtab.c (copys): Remove, use xstrdup instead.
7212
7213 2000-10-02  Akim Demaille  <akim@epita.fr>
7214
7215         * src/gram.h (associativity): New enum type which replaces the
7216         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7217         `right_assoc', `left_assoc' and `non_assoc'.
7218         Adjust all dependencies.
7219         * src/reader.c: Formatting changes.
7220         (LTYPESTR): Don't define it, use it as a literal in
7221         `reader_output_yylsp'.
7222         * src/symtab.h (symbol_class): New enum type which replaces the
7223         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7224         `sunknown', `stoken and `snterm'.
7225
7226 2000-10-02  Akim Demaille  <akim@epita.fr>
7227
7228         * src/getargs.c (fixed_outfiles): Rename as...
7229         (yaccflag): for consistency and accuracy.
7230         Adjust dependencies.
7231
7232 2000-10-02  Akim Demaille  <akim@epita.fr>
7233
7234         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7235         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
7236         difficult and introduced a lot of core dump.  It turns out that
7237         Bison used an implementation of `xmalloc' based on `calloc', and
7238         at various places it does depend upon the initialization to 0.  I
7239         have not tried to isolate the pertinent places, and all the former
7240         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
7241         someone should address this issue.
7242
7243         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7244         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7245         files.
7246         Adjust dependencies.

7252         Various anti-`extern in *.c' changes.
7253
7254         * src/system.h: Include `assert.h'.
7255
7256 2000-10-02  Akim Demaille  <akim@epita.fr>
7257
7258         * src/state.h (nstates, final_state, first_state, first_shift)
7259         (first_reduction): Move their exportation from here...
7260         * src/LR0.h: to here.
7261         Adjust dependencies.
7262         * src/getargs.c (statisticsflag): New variable.
7263         Add support for `--statistics'.

7265
7266         Remove a lot of now useless `extern' statements in most files.

7299         * src/reduce.h: New file.
7300         Propagate its inclusion.
7301         * src/reduce.c: Topological sort and other formatting changes.
7302         (bool, TRUE, FALSE): Move their definition to...
7303         * src/system.h: here.
7304
7305 2000-10-02  Akim Demaille  <akim@epita.fr>
7306
7307         * src/files.c: Formatting changes.
7308         (tryopen, tryclose, openfiles): Rename as...
7309         (xfopen, xfclose, open_files): this.
7310         (stringappend): static.
7311         * src/files.h: Complete the list of exported symbols.
7312         Propagate its use.
7313
7314 2000-10-02  Akim Demaille  <akim@epita.fr>
7315
7316         * src/reader.h: New file.
7317         Propagate its use instead of tedious list of `extern' and
7318         prototypes.
7319         * src/reader.c: Formatting changes, topological sort,
7320         s/register//.

7331
7332         * src/lalr.h: New file.

7336 2000-10-02  Akim Demaille  <akim@epita.fr>
7337
7338         * src/output.c (token_actions): Introduce a temporary array,
7339         YYDEFACT, that makes it possible for this function to use
7340         output_short_table.
7341
7342 2000-10-02  Akim Demaille  <akim@epita.fr>
7343
7344         `user_toknums' is output as a `short[]' in `output.c', while it is
7345         defined as a `int[]' in `reader.c'.  For consistency with the
7346         other output tables, `user_toknums' is now defined as a table of
7347         shorts.
7348
7349         * src/reader.c (user_toknums): Be a short table instead of an int
7350         table.
7351         Adjust dependencies.

7359 2000-10-02  Akim Demaille  <akim@epita.fr>
7360
7361         * src/output.c (output): Topological sort of the functions, in
7362         order to get rid of the `static' prototypes.
7363         No longer use `register'.
7364         * src/output.h: New file.
7365         Propagate its inclusion in files explicitly prototyping functions
7366         from output.c.

7388         inclusion.
7389         Don't define PARAMS.
7390         * src/system.h: Define PARAMS.
7391         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
7392         purpose of config.h.  system.h must not try to fix wrong
7393         definitions in config.h.
7394
7395 2000-09-20  Akim Demaille  <akim@epita.fr>

7407         Use these macros to test bison with options `', `--raw',
7408         `--debug', `--yacc', `--yacc --debug'.
7409

7471         (VERSION_STRING): Remove.
7472
7473 2000-04-14  Akim Demaille  <akim@epita.fr>
7474
7475         * src/reader.c (copy_comment2): New function, same as former

7530         * configure.in: Adjust.
7531         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's
7532         useless.

7555         the file name, not the whole `#line LINE FILE'.
7556
7557 2000-03-17  Akim Demaille  <akim@epita.fr>
7558
7559         On syntax errors, report the token on which we choked.
7560
7561         * src/bison.s1 (yyparse): In the label yyerrlab, when

7579
7580         * src/reader.c (copy_definition): Use copy_string and
7581         copy_comment.  Removed now unused `match', `ended',
7582         `cplus_comment'.
7583         (copy_comment, copy_string): Moved, to be visible from
7584         copy_definition.
7585
7586 2000-03-17  Akim Demaille  <akim@epita.fr>
7587
7588         * src/reader.c (copy_string): Declare `static inline'.  No
7589         problems with inline, since it is checked by configure.

7610
7611         Change the handling of @s so that they behave exactly like $s.
7612         There is now a pseudo variable @$ (readble and writable), location
7613         of the lhs of the rule (by default ranging from the location of
7614         the first symbol of the rhs, to the location of the last symbol,
7615         or, if the rhs is empty, YYLLOC).
7616
7617         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7618         yyval.
7619         (yyparse): When providing a default semantic action, provide a
7620         default location action.
7621         (after the $): No longer change `*YYLSP', just stack YYLOC the
7622         same way you stack YYVAL.
7623         * src/reader.c (read_declarations): Use warns.
7624         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7625         (copy_action, case '@'): Likewise.
7626         Use a standard error message, to save useless work from
7627         translators.
7628
7629 2000-03-17  Akim Demaille  <akim@epita.fr>
7630
7631         * src/bison.s1: Formatting and cosmetics changes.

7635 2000-03-17  Akim Demaille  <akim@epita.fr>
7636
7637         * src/bison.s1 (#line): All set to `#line' only, since the
7638         Makefile now handles them.
7639
7640 2000-03-16  Akim Demaille  <akim@epita.fr>
7641

7646
7647 2000-03-16  Akim Demaille  <akim@epita.fr>
7648
7649         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7650         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7651         One `#if YYDEBUG' remains, since it uses variables which are
7652         defined only if `YYDEBUG != 0'.
7653
7654 2000-03-16  Akim Demaille  <akim@epita.fr>
7655
7656         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
7657         and related variables so that the similarities are highlighted.
