 105
 106 2002-09-04  Jim Meyering  <jim@meyering.net>
 107

 112
 113         * configure.in: Rename as...

 128         (DISTCLEANFILES): Remove.
 129         * NEWS: Mention that GNU M4 is now required.  Clarify what is
 130         meant by "larger grammars".  Mention the pt_BR translation.

 141         (yyreportParseError): Use size_t for yysize.
 142         (yy_yypstack): No longer nested inside yypstates, as nested
 143         functions are not portable.  Do not assume size_t is the
 144         same width as int.
 145         (yypstates): Do not assume that ptrdiff_t is the same width
 146         as int, and similarly for yyposn and YYINDEX.
 147
 148         * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
 149
 150         * lib/Makefile.am (INCLUDES): Do not include from the intl
 151         directory, which has been removed.
 152         * src/Makefile.am (INCLUDES): Likewise.

 160
 161         * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):

 166         * lib/bbitset.h (BITSET_INDEX_MAX, BITSET_MSB): Likewise.
 167         * lib/bitset.h (bitset_set, bitset_reset): Likewise.

 171

 173         portability to one's complement hosts!).
 174         * lib/ebitset.c (ebitset_op1): Likewise.
 175         * lib/lbitset.c (lbitset_op1): Likewise.
 176
 177         * lib/argmatch.c, lib/quotearg.c, quotearg.h: Sync with GNU tar.
 178         * lib/argmatch.h, lib/basename.c, lib/dirname.c, lib/dirname.h,
 179         lib/hash.c, lib/hash.h, lib/strnlen.c, lib/xmalloc.c:
 180         Sync with fileutils.
 181         * lib/error.c, lib/getopt.c, lib/getopt.h, lib/getopt1.c,
 182         lib/gettext.h: Sync with diffutils.
 183
 184         * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
 185         lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
 186
 187         * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
 188         PROTOTYPES to check for prototypes, and "defined __STDC__" to
 189         check for void *.
 190
 191         * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
 192         size_t; the old version tried to do this but casted improperly.
 193         (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
 194         (bitset_test): Now returns int, not unsigned long.

 198         (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
 199         name locals "index", as it generates unnecessary warnings on some
 200         hosts that have an "index" function.
 201
 202         * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
 203         bitset_stats_read, bitset_stats_write): Wrap strings in _() if
 204         they need translation.
 205         * src/LR0.c (state_list_append, new_itemsets, get_state,
 206         append_states, generate_states): Likewise.
 207         * src/assoc.c (assoc_to_string): Likewise.

 216         * m4/Makefile.am (EXTRA_DIST): Remove codeset.m4,
 217         glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
 218         * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
 219         * m4/mbstate_t.m4: Sync with fileutils.
 220         * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
 221
 222         * po/LINGUAS: Add pt_BR.
 223         * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
 224         src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
 225         lib/timevar.c.
 226         Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
 227         manual recommends.
 228         Similarly, use src/scan-gram.l instead of src/scan-gram.c.
 229
 230         * src/complain.c (strerror_r): Remove decl; not needed.
 231         (strerror): Use same pattern as ../lib/error.c.
 232
 233         * src/files.c, src/files.h (compute_header_macro): Remove; unused.
 234
 235         * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
 236
 237         * src/main.c (main): Cast result of bindtextdomain and textdomain
 238         to void, to avoid a GCC warning when --disable-nls is in effect.
 239
 240         * src/scan-gram.l: Use strings rather than escapes when possible,
 241         to minimize the number of warnings from xgettext.
 242         (handle_action_dollar, handle_action_at): Don't use isdigit,
 243         as it mishandles negative chars and it may not work as expected
 244         outside the C locale.
 245
 246         * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
 247         this is a GCC extension and is not portable to other compilers.
 248
 249         * src/system.h (alloca): Use same pattern as ../lib/error.c.
 250         Do not include <ctype.h>; no longer needed.
 251         Do not include <malloc.h>; no longer needed (and generates
 252         warnings on OpenBSD 3.0).
 253
 254         * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
 255         it's not portable.
 256
 257         * tests/regression.at: Do not use 'cc -c input.c -o input';
 258         Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.
 259
 260         * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
 261         exit status as failure, not just exit status 1.  Sun C exits
 262         with status 2 sometimes.
 263
 264         * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
 265         Use it for the two large tests.
 266
 267 2002-08-02  Akim Demaille  <akim@epita.fr>
 268
 269         * src/conflicts.c (conflicts_output): Don't output rules never
 270         reduced here, since anyway that computation doesn't work.
 271         * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
 272         (rule_useless_p, rule_never_reduced_p): New.
 273         (grammar_rules_partial_print): Use a filter instead of a range.
 274         Display the title only if needed.
 275         (grammar_rules_print): Adjust.
 276         (grammar_rules_never_reduced_report): New.
 277         * src/tables.c (action_row): Move the computation of rules never
 278         reduced to...
 279         (token_actions): here.
 280         * src/main.c (main): Make the parser before making the report, so
 281         that rules never reduced are computed.
 282         Call grammar_rules_never_reduced_report.
 283         * src/print.c (print_results): Report rules never reduced.
 284         * tests/conflicts.at, tests/reduce.at: Adjust.
 285
 286 2002-08-01  Akim Demaille  <akim@epita.fr>
 287
 288         Instead of attaching lookaheads and duplicating the rules being
 289         reduced by a state, attach the lookaheads to the reductions.
 290
 291         * src/state.h (state_t): Remove the `lookaheads',
 292         `lookaheads_rule' member.
 293         (reductions_t): Add a `lookaheads' member.
 294         Use a regular array for the `rules'.
 295         * src/state.c (reductions_new): Initialize the lookaheads member
 296         to 0.
 297         (state_rule_lookaheads_print): Adjust.
 298         * src/state.h, src/state.c (state_reductions_find): New.
 299         * src/conflicts.c (resolve_sr_conflict, set_conflicts)
 300         (count_rr_conflicts): Adjust.
 301         * src/lalr.c (LArule): Remove.
 302         (add_lookback_edge): Adjust.
 303         (state_lookaheads_count): New.
 304         (states_lookaheads_initialize): Merge into...
 305         (initialize_LA): this.
 306         (lalr_free): Adjust.
 307         * src/main.c (main): Don't free nullable and derives too early: it
 308         is used by --verbose.
 309         * src/print.c, src/print_graph.c, src/tables.c: Adjust.
 310
 311 2002-08-01  Akim Demaille  <akim@epita.fr>
 312
 313         * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
 314         `rule_number_t**'.
 315         (set_derives, free_derives): Rename as...
 316         (derives_compute, derives_free): this.
 317         Adjust all dependencies.
 318         * src/nullable.c (set_nullable, free_nullable): Rename as...
 319         (nullable_compute, nullable_free): these.
 320         (rule_list_t): Store rule_t *, not rule_number_t.
 321         * src/state.c (state_rule_lookaheads_print): Directly compare rule
 322         pointers, instead of their numbers.
 323         * src/main.c (main): Call nullable_free, and derives_free earlier,
 324         as they were lo longer used.
 325
 326 2002-08-01  Akim Demaille  <akim@epita.fr>
 327
 328         * lib/timevar.c (get_time): Include children time.
 329         * src/lalr.h (LA, LArule): Don't export them: used with the
 330         state_t.
 331         * src/lalr.c (LA, LArule): Static.
 332         * src/lalr.h, src/lalr.c (lalr_free): New.
 333         * src/main.c (main): Call it.
 334         * src/tables.c (pack_vector): Check whether loc is >= to the
 335         table_size, not >.
 336         (pack_tables): Don't free froms, tos, conflict_tos, and pos...
 337         (tables_generate): do it, since that's also it which allocates
 338         them.
 339         Don't free LA and LArule, main does.
 340
 341 2002-07-31  Akim Demaille  <akim@epita.fr>

 388         * src/getargs.c (trace_args, trace_types, trace_argmatch): New.

 426         by conflicts.
 427
 428         * src/LR0.c (save_reductions): Don't make the final state too
 429         different: save its reduction (accept) instead of having a state
 430         without any action (no shift or goto, no reduce).
 431         Note: the final state is now a ``regular'' state, i.e., the
 432         parsers now contain `reduce 0' as default reduction.
 433         Nevertheless, since they decide to `accept' when yystate =
 434         final_state, they still will not reduce rule 0.

 468         Adjust.

 470 2002-07-29  Akim Demaille  <akim@epita.fr>
 471

 473         complain about the start symbol, not the axiom.
 474         Use its location.
 475         * tests/reduce.at (Empty Language): New.

 483         token_translations instead of `0'.
 484         * src/parse-gram.y (yyerror): Don't rely on yycontrol being
 485         visible here.
 486         * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
 487         for the time being: %locations ought to provide it to yyerror.
 488
 489 2002-07-25  Akim Demaille  <akim@epita.fr>
 490
 491         * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1652         Remove `%thong' support as it is undocumented, unused, duplicates
1653         `%token's job, and creates useless e-mail traffic with people who

1725
1726         * src/output.c (output_skeleton): Put an explicit path in front of
1727         the skeleton file name, rather than relying on the -I directory,

1801
1802         * data/bison.simple (yyparse): Correct error handling to conform to

1811         * data/bison.simple (yyr1): Don't use yy_token_number_type as element

1817         * data/bison.c++ (r1_): Parallel change to yyr1 in bison.simple---

1990
1991         * src/reader.c (parse_braces): Merge into...
1992         (parse_action): this.
1993
1994 2002-05-02  Akim Demaille  <akim@epita.fr>

2032         Note: this patch partially drops `semantic-parser' support: it
2033         always does `rule_length - n', where semantic parsers ought to
2034         always use `-n'.

2085
2086         * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
2087         `b4_post_prologue' instead of `b4_prologue'.

2089         * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
2090         muscles.

2104
2105         (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
2106         YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
2107         if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial

2128
2129         * src/output.c (table_size, table_grow): New.
2130         (MAXTABLE): Remove, replace uses with table_size.
2131         (pack_vector): Instead of dying when the table is too big, grow it.

2134
2135         * data/bison.simple (yyr1): Its type is that of a token number.

2140
2141         * src/reader.c (token_translations_init): 256 is now the default
2142         value for the error token, i.e., it will be assigned another
2143         number if the user assigned 256 to one of her tokens.
2144         (reader): Don't force 256 to error.

2150
2151 2002-04-22  Akim Demaille  <akim@epita.fr>

2174         (Table of Symbols): Describe $$, $n, @$, and @n.

2185
2186 2002-04-09  Akim Demaille  <akim@epita.fr>
2187
2188         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2189         full stderr, and strip it according to the bison options, instead
2190         of composing the error message from different bits.
2191         This makes it easier to check for several error messages.
2192         Adjust all the invocations.
2193         Add an invocation exercising the error token.
2194         Add an invocation demonstrating a stupid error message.
2195         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
2196         Adjust the tests.
2197         Error message are for stderr, not stdout.

2200
2201         * src/gram.h, src/gram.c (error_token_number): Remove, use
2202         errtoken->number.
2203         * src/reader.c (reader): Don't specify the user token number (2)
2204         for $undefined, as it uselessly prevents using it.
2205         * src/gram.h (token_number_t): Move to...
2206         * src/symtab.h: here.
2207         (state_t.number): Is a token_number_t.
2208         * src/print.c, src/reader.c: Use undeftoken->number instead of
2209         hard coded 2.
2210         (Even though this 2 is not the same as above: the number of the
2211         undeftoken remains being 2, it is its user token number which
2212         might not be 2).
2213         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2214         `user_token_number_max'.
2215         Output `undef_token_number'.
2216         * data/bison.simple, data/bison.c++: Use them.
2217         Be sure to map invalid yylex return values to
2218         `undef_token_number'.  This saves us from gratuitous SEGV.
2219
2220         * tests/conflicts.at (Solved SR Conflicts)
2221         (Unresolved SR Conflicts): Adjust.
2222         * tests/regression.at (Web2c Actions): Adjust.

2227         Adding #line.
2228         Remove the duplicate `typedefs'.
2229         (RhsNumberType): Fix the declaration and various other typos.
2230         Use __ofile__.
2231         * data/bison.simple: Use __ofile__.
2232         * src/scan-skel.l: Handle __ofile__.

2235
2236         * src/gram.h (item_number_t): New, the type of item numbers in
2237         RITEM.  Note that it must be able to code symbol numbers as
2238         positive number, and the negation of rule numbers as negative
2239         numbers.
2240         Adjust all dependencies (pretty many).
2241         * src/reduce.c (rule): Remove this `short *' pointer: use
2242         item_number_t.
2243         * src/system.h (MINSHORT, MAXSHORT): Remove.
2244         Include `limits.h'.
2245         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
2246         (shortcpy): Remove.
2247         (MAXTABLE): Move to...
2248         * src/output.c (MAXTABLE): here.
2249         (prepare_rules): Use output_int_table to output rhs.
2250         * data/bison.simple, data/bison.c++: Adjust.
2251         * tests/torture.at (Big triangle): Move the limit from 254 to
2252         500.
2253         * tests/regression.at (Web2c Actions): Ajust.
2254
2255         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2256         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2257         passes, but produces negative #line number, once fixed, GCC is
2258         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2259         C), it passes.
2260         * src/state.h (state_h): Code input lines on ints, not shorts.
2261
2262 2002-04-08  Akim Demaille  <akim@epita.fr>

2277         New.
2278         Use them to define yy_token_number_type/TokenNumberType.
2279         Use this type for yytranslate.
2280         * tests/torture.at (Big triangle): Push the limit from 124 to

2392
2393         * src/output.c (output_token_translations): Rename as...

2410         newly created state.
2411         Adjust to initialize first_state and last_state if needed.

2413         (new_states): Create the itemset of the initial state, and use
2414         new_state.
2415         * src/closure.c (closure): Now that the initial state has its
2416         items properly set, there is no need for a special case when
2417         creating `ruleset'.
2418
2419         As a result, now the rule 0, reducing to $axiom, is visible in the
2420         outputs.  Adjust the test suite.

2433 2002-04-07  Akim Demaille  <akim@epita.fr>

2452         the end of `rules', and count them out of `nrules'.
2453         (reduce_output, dump_grammar): Adjust.
2454         * src/print.c (print_grammar): It is no longer needed to check for
2455         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
2456         * tests/reduce.at (Reduced Automaton): New test.
2457
2458 2002-04-07  Akim Demaille  <akim@epita.fr>
2459
2460         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
2461         lacking `+ 1' to nrules, Bison reported as useless a token if it
2462         was used solely to set the precedence of the last rule...
2463

2465
2466         * data/bison.c++, data/bison.simple: Don't output the current file

2748         Fileutils 4.1.5.
2749         * configure.in: Invoke UTILS_FUNC_MKSTEMP.
2750         * src/output.c (output_skeleton): Use mkstemp to create a real
2751         temporary file.
2752         Move the filling of `skeleton' and its muscle to...
2753         (prepare): here.
2754         (output): Move the definition of the prologue muscle to...
2755         (prepare): here.
2756         * src/system.h (DEFAULT_TMPDIR): New.
2757
2758 2002-02-14  Paul Eggert  <eggert@twinsun.com>
2759
2760         Remove the support for C++ namespace cleanliness; it was
2761         causing more problems than it was curing, since it didn't work
2762         properly on some nonstandard C++ compilers.  This can wait
2763         for a proper C++ parser.
2764
2765         * NEWS: Document this.
2766         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
2767         of C++, as it's treated like C now.
2768         * src/bison.simple (YYSTD): Remove.
2769         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
2770         Treat C++ just like Standard C instead of trying to support
2771         namespace cleanliness.
2772
2773 2002-02-14  Akim Demaille  <akim@epita.fr>
2774
2775         * tests/regression.at (else): Adjust to Andreas' change.
2776
2777 2002-02-14  Akim Demaille  <akim@epita.fr>
2778
2779         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
2780
2781 2002-02-13  Andreas Schwab  <schwab@suse.de>
2782
2783         * src/output.c (output_rule_data): Don't output NULL, it might
2784         not be defined yet.
2785
2786 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
2787
2788         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
2789         (Copyright notice): Update.
2790
2791 2002-02-11  Akim Demaille  <akim@epita.fr>
2792
2793         * tests/regression.at (%nonassoc and eof): Don't include
2794         nonportable headers.
2795
2796 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
2797
2798         * data/bison.c++: Correct error recovery.  Make the user able to
2799         initialize the starting location.
2800
2801 2002-02-07  Akim Demaille  <akim@epita.fr>
2802
2803         * tests/input.at: New.
2804
2805 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2806
2807         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
2808         more consistent when naming methods and variables.  Put preprocessor
2809         directives around tables only needed for debugging.
2810
2811 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2812
2813         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
2814         C++ parsers.
2815         (yy::b4_name::parse): Use print_.
2816
2817 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2818
2819         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
2820
2821 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2822
2823         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
2824         C++ parsers.
2825         (yy::b4_name::parse): Build verbose error messages, and use error_.
2826
2827 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
2828
2829         * data/bison.c++: Fix m4 quoting in comments.
2830
2831 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
2832
2833         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
2834         not expanded by m4.
2835
2836 2002-02-05  Akim Demaille  <akim@epita.fr>
2837
2838         * data/bison.c++: Adjust to the M4 back end.
2839         More is certainly needed.
2840
2841 2002-02-05  Akim Demaille  <akim@epita.fr>
2842
2843         Give a try to M4 as a back end.
2844
2845         * lib/readpipe.c: New, from wdiff.
2846         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
2847         BISON_HAIRY.
2848         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
2849         specific values.  Now it is m4 that performs the lookup.
2850         * src/parse-skel.y: Remove.
2851         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
2852         * src/output.c (actions_output, guards_output)
2853         (token_definitions_output): No longer keeps track of the output
2854         line number, hence remove the second argument.
2855         (guards_output): Check against the guard member of a rule, not the
2856         action member.
2857         Adjust callers.
2858         (output_skeleton): Don't look for the skeleton location, let m4 do
2859         that.
2860         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
2861         file will be used.
2862         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2863         (prepare): Given that for the time being changesyntax is not
2864         usable in M4, rename the muscles using `-' to `_'.
2865         Define `defines_flag', `output_parser_name' and `output_header_name'.
2866         * src/output.h (actions_output, guards_output)
2867         (token_definitions_output): Adjust prototypes.
2868         * src/scan-skel.l: Instead of scanning the skeletons, it now
2869         processes the output of m4: `__oline__' and `#output'.
2870         * data/bison.simple: Adjust to be used by M4(sugar).
2871         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2872         to date.
2873         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
2874         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
2875         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
2876         shamelessly stolen from CVS Autoconf.
2877
2878 2002-02-05  Akim Demaille  <akim@epita.fr>
2879
2880         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
2881         * configure.in: Check for the declarations of free and malloc.
2882         * src/muscle_tab.c: Adjust.
2883
2884 2002-02-05  Akim Demaille  <akim@epita.fr>
2885
2886         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
2887         which have no values.
2888
2889 2002-02-05  Akim Demaille  <akim@epita.fr>
2890
2891         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
2892         * data/: here.
2893
2894 2002-01-29  Paul Eggert  <eggert@twinsun.com>
2895
2896         * src/bison.simple (YYSIZE_T): Do not define merely because
2897         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
2898         On some platforms, <alloca.h> does not declare YYSTD (size_t).
2899
2900 2002-01-27  Akim Demaille  <akim@epita.fr>
2901
2902         Fix `%nonassoc and eof'.
2903
2904         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
2905         which were not properly copied!  Replace
2906         memcpy (res->errs, src->errs, src->nerrs);
2907         with
2908         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2909         !!!
2910         * tests/regression.at (%nonassoc and eof): Adjust to newest
2911         Autotest: `.' is not in the PATH.
2912
2913 2002-01-27  Akim Demaille  <akim@epita.fr>
2914
2915         * tests/sets.at (AT_EXTRACT_SETS): New.
2916         (Nullable): Use it.
2917         (Firsts): New.
2918
2919 2002-01-26  Akim Demaille  <akim@epita.fr>
2920
2921         * tests/actions.at, tests/calc.at, tests/headers.at,
2922         * tests/torture.at: Adjust to the newest Autotest which no longer
2923         forces `.' in the PATH.
2924
2925 2002-01-25  Akim Demaille  <akim@epita.fr>
2926
2927         * tests/regression.at (%nonassoc and eof): New.
2928         Suggested by Robert Anisko.
2929
2930 2002-01-24  Akim Demaille  <akim@epita.fr>
2931
2932         Bison dumps core when trying to complain about broken input files.
2933         Reported by Cris van Pelt.
2934
2935         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2936         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2937         into...
2938         (Invalid inputs): Strengthen: exercise parse_percent_token.
2939
2940 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
2941
2942         * src/Makefile.am: Add bison.c++.
2943         * src/bison.c++: New skeleton.
2944
2945 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
2946
2947         * po/it.po: New.
2948
2949 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
2950
2951         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2952
2953 2002-01-20  Marc Autret  <marc@gnu.org>
2954
2955         * src/files.c (compute_output_file_names): Fix
2956
2957 2002-01-20  Marc Autret  <marc@gnu.org>
2958
2959         * tests/output.at: New test.
2960         * src/files.c (compute_base_names): Don't map extensions when
2961         the YACC flag is set, use defaults.
2962         Reported by Evgeny Stambulchik.
2963
2964 2002-01-20  Marc Autret  <marc@gnu.org>
2965
2966         * src/system.h: Need to define __attribute__ away for non-GCC
2967         compilers as well (i.e. the vendor C compiler).
2968         Suggested by Albert Chin-A-Young.
2969
2970 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
2971
2972         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2973         canonical definition.
2974         * src/system.h: Use the canonical definition for PARAMS (avoids
2975         a conflict with the macro from lib/hash.h).
2976
2977 2002-01-11  Akim Demaille  <akim@epita.fr>
2978
2979         * configure.in: Use AC_FUNC_STRNLEN.
2980         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2981
2982 2002-01-09  Akim Demaille  <akim@epita.fr>
2983
2984         * src/files.c, src/files.h (output_infix): New.
2985         (tab_extension): Remove.
2986         (compute_base_names): Compute the former, drop the latter.
2987         * src/output.c (prepare): Insert the muscles `output-infix', and
2988         `output-suffix'.
2989         * src/parse-skel.y (string, string.1): New.
2990         (section.header): Use it.
2991         (section.yacc): Remove.
2992         (prefix): Remove too.
2993         * src/scan-skel.l: Adjust.
2994         * src/bison.simple, src/bison.hairy: Adjust.
2995
2996 2002-01-09  Akim Demaille  <akim@epita.fr>
2997
2998         * configure.in (WERROR_CFLAGS): Compute it.
2999         * src/Makefile.am (CFLAGS): Pass it.
3000         * tests/atlocal.in (CFLAGS): Idem.
3001         * src/files.c: Fix a few warnings.
3002         (get_extension_index): Remove, unused.
3003
3004 2002-01-08  Akim Demaille  <akim@epita.fr>
3005
3006         * src/getargs.c (AS_FILE_NAME): New.
3007         (getargs): Use it to convert DOSish file names.
3008         * src/files.c (base_name): Rename as full_base_name to avoid
3009         clashes with `base_name ()'.
3010         (filename_split): New.
3011         (compute_base_names): N-th rewrite, using filename_split.
3012
3013 2002-01-08  Akim Demaille  <akim@epita.fr>
3014
3015         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3016         New, stolen from the Fileutils 4.1.
3017         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3018         * configure.in: Check for the presence of memrchr, and of its
3019         prototype.
3020
3021 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
3022
3023         * lib/hash.h (__P): Added definition for this macro.
3024         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3025         BUILT_SOURCES, to ensure they are generated first.
3026         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3027         %error-verbose to allow bootstrapping with bison 1.30x.
3028
3029 2002-01-06  Akim Demaille  <akim@epita.fr>
3030
3031         * src/reader.c (parse_braces): Don't fetch the next char, the
3032         convention is to fetch on entry.
3033         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3034         'switch' without a following semicolon.
3035         * tests/regression.at (braces parsing): New.
3036
3037 2002-01-06  Akim Demaille  <akim@epita.fr>
3038
3039         Bison is dead wrong in its RR conflict reports.
3040
3041         * tests/torture.at (GNU Cim Grammar): New.
3042         * src/conflicts.c (count_rr_conflicts): Fix.
3043
3044 2002-01-06  Akim Demaille  <akim@epita.fr>
3045
3046         Creating package.m4 from configure.ac causes too many problems.
3047
3048         * tests/Makefile.am (package.m4): Create it by hand,
3049         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3050
3051 2002-01-06  Akim Demaille  <akim@epita.fr>
3052
3053         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3054         skeleton.h.
3055
3056 2002-01-04  Paul Eggert  <eggert@twinsun.com>
3057
3058         * doc/bison.texinfo (Debugging):
3059         Remove YYSTDERR; it's no longer defined or used.
3060         Also, s/cstdio.h/cstdio/.
3061
3062 2002-01-03  Akim Demaille  <akim@epita.fr>
3063
3064         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3065
3066 2002-01-03  Akim Demaille  <akim@epita.fr>
3067
3068         * src/parse-skel.y (process_skeleton): Don't bind the parser's
3069         tracing code to --trace, wait for a better --trace option, with
3070         args.
3071
3072 2002-01-03  Akim Demaille  <akim@epita.fr>
3073
3074         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3075         The ISO C++ standard is extremely clear about it: stderr is
3076         considered a macro, not a regular symbol (see table 94 `Header
3077         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3078         Therefore std:: does not apply to it.  It still does with fprintf.
3079         Also, s/cstdio.h/cstdio/.
3080
3081 2002-01-03  Akim Demaille  <akim@epita.fr>
3082
3083         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3084         for non system headers.
3085
3086 2002-01-02  Akim Demaille  <akim@epita.fr>
3087
3088         Equip the skeleton chain with location tracking, runtime trace,
3089         pure parser and scanner.
3090
3091         * src/parse-skel.y: Request a pure parser, locations, and prefix
3092         renaming.
3093         (%union): Having several members with the same type does not help
3094         type mismatches, simplify.
3095         (YYPRINT, yyprint): New.
3096         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3097         (skel_error): this.
3098         Handle locations.
3099         * src/scan-skel.l: Adjust to these changes.
3100         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3101         (LOCATION_PRINT, skel_control_t): New.
3102
3103 2001-12-30  Akim Demaille  <akim@epita.fr>
3104
3105         * src/parse-skel.y: Get rid of the shift/reduce conflict:
3106         replace `gb' with BLANKS.
3107         * src/scan-skel.l: Adjust.
3108
3109 2001-12-30  Akim Demaille  <akim@epita.fr>
3110
3111         * src/system.h: We don't need nor want bcopy.
3112         Throw away MS-DOS crap: we don't need getpid.
3113         * configure.in: We don't need strndup.  It was even causing
3114         problems: because Flex includes the headers *before* us,
3115         _GNU_SOURCE is not defined by config.h, and therefore strndup was
3116         not visible.
3117         * lib/xstrndup.c: New.
3118         * src/scan-skel.l: Use it.
3119         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3120         * src/parse-skel.y: Use %directives instead of #defines.
3121
3122 2001-12-30  Akim Demaille  <akim@epita.fr>
3123
3124         * src/skeleton.h: New.
3125         * src/output.c (output_parser, output_master_parser): Remove, dead
3126         code.
3127         * src/output.h (get_lines_number, actions_output, guards_output)
3128         (token_definitions_output): Prototype them.
3129         * src/parse-skel.y: Add the license notice.
3130         Include output.h and skeleton.h.
3131         (process_skeleton): Returns void, and takes a single parameter.
3132         * src/scan-skel.l: Add the license notice.
3133         Include skeleton.h.
3134         Don't use %option yylineno: it seems that then Flex imagines
3135         REJECT has been used, and therefore it won't reallocate its
3136         buffers (which makes no other sense to me than a bug).  It results
3137         in warnings for `unused: yy_flex_realloc'.
3138
3139 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
3140
3141         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3142         (MUSCLE_INSERT_PREFIX): ...to there.
3143         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3144         (MUSCLE_INSERT_PREFIX): Move from here...
3145
3146         * src/bison.hairy: Add a section directive.  Put braces around muscle
3147         names.  This parser skeleton is still broken, but Bison should not
3148         choke on a bad muscle 'syntax'.
3149         * src/bison.simple: Add a section directive.  Put braces around muscle
3150         names.
3151
3152         * src/files.h (strsuffix, stringappend): Add declarations.
3153         (tab_extension): Add declaration.
3154         (short_base_name): Add declaration.
3155
3156         * src/files.c (strsuffix, stringappend): No longer static.  These
3157         functions are used in the skeleton parser.
3158         (tab_extension): New.
3159         (compute_base_names): Use the computations done in this function
3160         to guess if the generated parsers should have '.tab' in their
3161         names.
3162         (short_base_name): No longer static.
3163
3164         * src/output.c (output_skeleton): New.
3165         (output): Disable call to output_master_parser, and give a try to
3166         a new skeleton handling system.
3167         (guards_output, actions_output): No longer static.
3168         (token_definitions_output, get_lines_number): No longer static.
3169
3170         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3171
3172         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3173         parse-skel.y.
3174
3175         * src/parse-skel.y: New file.
3176         * src/scan-skel.l: New file.
3177
3178 2001-12-29  Akim Demaille  <akim@epita.fr>
3179
3180         %name-prefix is broken.
3181
3182         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3183         Adjust all dependencies.
3184         * tests/headers.at (export YYLTYPE): Strengthen this test: use
3185         %name-prefix.
3186
3187         Renaming yylval but not yylloc is not consistent.  Now we do.
3188
3189         * src/bison.simple: Prefix yylloc if used.
3190         * doc/bison.texinfo (Decl Summary): Document that.
3191
3192 2001-12-29  Akim Demaille  <akim@epita.fr>
3193
3194         * doc/bison.texinfo: Promote `%long-directive' over
3195         `%long_directive'.
3196         Remove all references to fixed-output-files, yacc is enough.
3197
3198 2001-12-29  Akim Demaille  <akim@epita.fr>
3199
3200         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3201         user prologue.  These are defaults.
3202         * tests/actions.at (Mid-rule actions): Make sure the user can
3203         define YYDEBUG and YYERROR_VERBOSE.
3204
3205 2001-12-29  Akim Demaille  <akim@epita.fr>
3206
3207         * src/output.c (header_output): Don't forget to export YYLTYPE and
3208         yylloc.
3209         * tests/headers.at (export YYLTYPE): New, make sure it does.
3210         * tests/regression.at (%union and --defines, Invalid CPP headers):
3211         Move to...
3212         * tests/headers.at: here.
3213
3214 2001-12-29  Akim Demaille  <akim@epita.fr>
3215
3216         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3217
3218 2001-12-29  Akim Demaille  <akim@epita.fr>
3219
3220         * tests/actions.at (Mid-rule actions): Output on a single line
3221         instead of several.
3222
3223 2001-12-29  Akim Demaille  <akim@epita.fr>
3224
3225         * doc/bison.texinfo: Formatting changes.
3226
3227 2001-12-29  Akim Demaille  <akim@epita.fr>
3228
3229         Don't store the token defs in a muscle, just be ready to output it
3230         on command.  Now possible via `symbols'.  Fixes a memory leak.
3231
3232         * src/output.c (token_definitions_output): New.
3233         (output_parser, header_output): Use it.
3234         * src/reader.c (symbols_save): Remove.
3235
3236 2001-12-29  Akim Demaille  <akim@epita.fr>
3237
3238         * src/bison.simple: Do not provide a default for YYSTYPE and
3239         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
3240         default.
3241
3242 2001-12-29  Akim Demaille  <akim@epita.fr>
3243
3244         Mid-rule actions are simply... ignored!
3245
3246         * src/reader.c (readgram): Be sure to attach mid-rule actions to
3247         the empty-rule associated to the dummy symbol, not to the host
3248         rule.
3249         * tests/actions.at (Mid-rule actions): New.
3250
3251 2001-12-29  Akim Demaille  <akim@epita.fr>
3252
3253         Memory leak.
3254
3255         * src/reader.c (reader): Free grammar.
3256
3257 2001-12-29  Akim Demaille  <akim@epita.fr>
3258
3259         Memory leak.
3260
3261         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3262         since it allocates it for each state, although only one is needed.
3263         (allocate_storage): Do it here.
3264
3265 2001-12-29  Akim Demaille  <akim@epita.fr>
3266
3267         * src/options.h, src/options.c (create_long_option_table): Rename
3268         as...
3269         (long_option_table_new): this, with a clearer prototype.
3270         (percent_table): Remove, unused,
3271         * src/getargs.c (getargs): Adjust.
3272
3273 2001-12-29  Akim Demaille  <akim@epita.fr>
3274
3275         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3276         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3277         as states.
3278
3279 2001-12-29  Akim Demaille  <akim@epita.fr>
3280
3281         * src/lalr.c (build_relations): Rename `states' as `states1'.
3282         Sorry, I don't understand exactly what it is, no better name...
3283
3284 2001-12-29  Akim Demaille  <akim@epita.fr>
3285
3286         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3287         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3288         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3289         as rules.
3290
3291 2001-12-29  Akim Demaille  <akim@epita.fr>
3292
3293         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3294         ago.
3295
3296 2001-12-29  Akim Demaille  <akim@epita.fr>
3297
3298         * src/reader.c, src/reader.h (user_toknums): Remove.
3299         Adjust all users to use symbols[i]->user_token_number.
3300
3301 2001-12-29  Akim Demaille  <akim@epita.fr>
3302
3303         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3304         Adjust all users to use symbols[i]->prec or ->assoc.
3305
3306 2001-12-29  Akim Demaille  <akim@epita.fr>
3307
3308         * src/reader.c, src/reader.h (tags): Remove.
3309         Adjust all users to use symbols[i]->tag.
3310
3311 2001-12-29  Akim Demaille  <akim@epita.fr>
3312
3313         * src/gram.h, src/gram.c (symbols): New, similar to state_table
3314         and rule_table.
3315         * src/reader.c (packsymbols): Fill this table.
3316         Drop sprec.
3317         * src/conflicts.c (resolve_sr_conflict): Adjust.
3318         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3319         single table.
3320         Use symbols[i]->tag instead of tags[i].
3321
3322 2001-12-29  Akim Demaille  <akim@epita.fr>
3323
3324         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3325         In addition, put a comment in there, to replace...
3326         * tests/regression.at (%union and C comments): Remove.
3327
3328 2001-12-29  Akim Demaille  <akim@epita.fr>
3329
3330         * tests/regression.at (Web2c Actions): Blindly move the actual
3331         output as expected output.  The contents *seem* right to me, but I
3332         can't pretend reading perfectly parser tables...  Nonetheless, all
3333         the other tests pass correctly, the table look OK, even though the
3334         presence of `$axiom' is to be noted: AFAICS it is useless (but
3335         harmless).
3336
3337 2001-12-29  Akim Demaille  <akim@epita.fr>
3338
3339         * src/reader.c (readgram): Don't add the rule 0 if there were no
3340         rules read.  In other words, add it _after_ having performed
3341         grammar sanity checks.
3342         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3343
3344 2001-12-29  Akim Demaille  <akim@epita.fr>
3345
3346         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3347         visible, and some states have now a different number.
3348
3349 2001-12-29  Akim Demaille  <akim@epita.fr>
3350
3351         * src/reader.c (readgram): Bind the initial rule's lineno to that
3352         of the first rule.
3353         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3354         (Solved SR Conflicts): Adjust rule 0's line number.
3355
3356 2001-12-29  Akim Demaille  <akim@epita.fr>
3357
3358         Fix the `GAWK Grammar' failure.
3359
3360         * src/LR0.c (final_state): Initialize to -1 so that we do compute
3361         the reductions of the first state which was mistakenly confused
3362         with the final state because precisely final_state was initialized
3363         to 0.
3364         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3365         now noticed by Bison.
3366         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3367         have a reduction on $default.
3368
3369 2001-12-29  Akim Demaille  <akim@epita.fr>
3370
3371         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3372         rule line numbers.
3373         * src/closure.c (print_closure): Likewise.
3374         * src/derives.c (print_derives): Likewise.
3375         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3376         now.
3377
3378 2001-12-29  Akim Demaille  <akim@epita.fr>
3379
3380         * src/lalr.c (lookaheads_print): New.
3381         (lalr): Call it when --trace-flag.
3382         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3383         are dumped.
3384
3385 2001-12-29  Akim Demaille  <akim@epita.fr>
3386
3387         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3388         when walking through ritem, even via rule->rhs.
3389         * src/reduce.c (dump_grammar, useful_production, reduce_output)
3390         (useful_production, useless_nonterminals): Likewise.
3391         (reduce_grammar_tables): Likewise, plus update nritems.
3392         * src/nullable.c (set_nullable): Likewise.
3393         * src/lalr.c (build_relations): Likewise.
3394         * tests/sets.at (Nullable): Adjust.
3395         Fortunately, now, the $axiom is no longer nullable.
3396
3397 2001-12-29  Akim Demaille  <akim@epita.fr>
3398
3399         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3400         the 0-sentinel.
3401         * src/gram.c (ritem_longest_rhs): Likewise.
3402         * src/reduce.c (nonterminals_reduce): Likewise.
3403         * src/print_graph.c (print_graph): Likewise.
3404         * src/output.c (output_rule_data): Likewise.
3405         * src/nullable.c (set_nullable):  Likewise.
3406
3407 2001-12-29  Akim Demaille  <akim@epita.fr>
3408
3409         * src/output.c: Comment changes.
3410
3411 2001-12-27  Paul Eggert  <eggert@twinsun.com>
3412
3413         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3414         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3415         Sparc, as they were causing more porting problems than the
3416         (minor) performance improvement was worth.
3417
3418         Also, catch up with 1.31's YYSTD.
3419
3420 2001-12-27  Akim Demaille  <akim@epita.fr>
3421
3422         * src/output.c (output_gram): Rely on nritems, not the
3423         0-sentinel.  See below.
3424         Use -1 as separator, not 0.
3425         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3426         Rely on -1 as separator in yyrhs, instead of 0.
3427         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3428         twice `Now at end of input', therefore there are two lines less to
3429         expect.
3430
3431 2001-12-27  Akim Demaille  <akim@epita.fr>
3432
3433         * tests/regression.at (Unresolved SR Conflicts):
3434         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3435         below.
3436
3437 2001-12-27  Akim Demaille  <akim@epita.fr>
3438
3439         * src/LR0.c (new_state): Recognize the final state by the fact it
3440         is reached by eoftoken.
3441         (insert_start_shifting_state, insert_eof_shifting_state)
3442         (insert_accepting_state, augment_automaton): Remove, since now
3443         these states are automatically computed from the initial state.
3444         (generate_states): Adjust.
3445         * src/print.c: When reporting a rule number to the user, substract
3446         1, so that the axiom rule is rule 0, and the first user rule is 1.
3447         * src/reduce.c: Likewise.
3448         * src/print_graph.c (print_core): For the time being, just as for
3449         the report, depend upon --trace-flags to dump the full set of
3450         items.
3451         * src/reader.c (readgram): Once the grammar read, insert the rule
3452         0: `$axiom: START-SYMBOL $'.
3453         * tests/set.at: Adjust: rule 0 is now displayed, and since the
3454         number of the states has changed (the final state is no longer

3458
3459         Try to make the use of the eoftoken valid.  Given that its value
3460         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3461         is used instead of > 0 where appropriate, (ii), depend upon nritems
3462         instead of the 0-sentinel.
3463
3464         * src/gram.h, src/gram.c (nritems): New.
3465         Expected to be duplication of nitems, but for the time being...
3466         * src/reader.c (packgram): Assert nritems and nitems are equal.
3467         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3468         * src/closure.c (print_closure, print_fderives): Likewise.

3473 2001-12-27  Akim Demaille  <akim@epita.fr>
3474
3475         * src/main.c (main): If there are complains after grammar
3476         reductions, then output the report anyway if requested, then die.
3477         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3478         * src/reader.c (eoftoken): New.
3479         (parse_token_decl): If the token being defined has value `0', it
3480         is the eoftoken.
3481         (packsymbols): No longer hack `tags' to insert `$' by hand.
3482         Be sure to preserve the value of the eoftoken.
3483         (reader): Make sure eoftoken is defined.
3484         Initialize nsyms to 0: now eoftoken is created just like the others.
3485         * src/print.c (print_grammar): Don't special case the eof token.
3486         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3487         lie anyway, albeit pleasant.
3488         * tests/calc.at: Exercise error messages with eoftoken.
3489         Change the grammar so that empty input is invalid.
3490         Adjust expectations.
3491         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3492
3493 2001-12-27  Akim Demaille  <akim@epita.fr>
3494
3495         * configure.in: Check the protos of strchr ans strspn.
3496         Replace strchr if needed.
3497         * src/system.h: Provide the protos of strchr, strspn and memchr if
3498         missing.
3499         * lib/strchr.c: New.
3500         * src/reader.c (symbols_save): Use strchr.
3501
3502 2001-12-27  Akim Demaille  <akim@epita.fr>
3503
3504         * src/print.c, src/print_graph.c (escape): New.
3505         Use it to quote the TAGS outputs.
3506         * src/print_graph.c (print_state): Now errors are in red, and
3507         reductions in green.
3508         Prefer high to wide: output the state number on a line of its own.
3509
3510 2001-12-27  Akim Demaille  <akim@epita.fr>

3538         print_reductions.
3539         (print_results): Adjust.
3540         (print_shifts, print_gotos, print_errs): New, extracted from...
3541         (print_actions): here.
3542         * src/print_graph.c (print_actions): Remove dead code.
3543
3544 2001-12-27  Akim Demaille  <akim@epita.fr>
3545
3546         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3547         `$n' and `@n'.
3548
3549 2001-12-27  Akim Demaille  <akim@epita.fr>
3550
3551         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3552         (build_relations): Adjust.
3553
3554 2001-12-27  Akim Demaille  <akim@epita.fr>

3557         duplication.

3560

3562
3563 2001-12-27  Akim Demaille  <akim@epita.fr>
3564
3565         * src/files.c, src/files.h (guard_obstack): Remove.
3566         * src/output.c (output): Adjust.
3567         * src/reader.c (parse_braces): New, factoring...
3568         (copy_action, copy_guard): these two which are renamed as...
3569         (parse_action, parse_guard): these.
3570         As a voluntary consequence, using braces around guards is now
3571         mandatory.
3572
3573 2001-12-27  Akim Demaille  <akim@epita.fr>
3574
3575         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3576         * src/reader.c (symbol_list): `guard' and `guard_line' are new
3577         members.
3578         (symbol_list_new): Adjust.
3579         (copy_action): action_line is the first line, not the last.
3580         (copy_guard): Just as for actions, store the `action' only, not
3581         the switch/case/break flesh.
3582         Don't parse the user action that might follow the guard, let...
3583         (readgram): do it, i.e., now, there can be an action after a
3584         guard.
3585         In other words the guard is just explicitly optional.
3586         (packgram): Adjust.
3587         * src/output.c (guards_output): New.
3588         (output_parser): Call it when needed.
3589         (output): Also free the guard and attrs obstacks.
3590         * src/files.c, src/files.h (obstack_save): Remove.
3591         (output_files): Remove.
3592         As a result, if one needs the former `.act' file, using an
3593         appropriate skeleton which requires actions and guards is now
3594         required.
3595         * src/main.c (main): Adjust.
3596         * tests/semantic.at: New.
3597         * tests/regression.at: Use `input.y' as input file name.
3598         Avoid 8+3 problems by requiring input.c when the test needs the
3599         parser.

3602

3606 2001-12-27  Akim Demaille  <akim@epita.fr>
3607
3608         All the hacks using a final pseudo state are now useless.
3609
3610         * src/LR0.c (set_state_table): state_table holds exactly nstates.
3611         * src/lalr.c (nLA): New.
3612         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3613         instead of lookaheadsp from the pseudo state (nstate + 1).
3614
3615 2001-12-27  Akim Demaille  <akim@epita.fr>
3616
3617         * src/output.c (action_row, token_actions): Use a state_t instead
3618         of a integer, and nlookaheads instead of the following state's
3619         lookaheadsp.
3620
3621 2001-12-27  Akim Demaille  <akim@epita.fr>

3625         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3626         (conflicts_print, print_reductions): Use a state_t instead of an
3627         integer when referring to a state.
3628         As much as possible, depend upon nlookaheads, instead of the
3629         `lookaheadsp' member of the following state (since lookaheads of
3630         successive states are successive, the difference between state n + 1
3631         and n served as the number of lookaheads for state n).
3632         * src/lalr.c (add_lookback_edge): Likewise.
3633         * src/print.c (print_core, print_actions, print_state)

3649         duplicates ntokens.
3650         * src/bison.simple: Formatting/comment changes.
3651         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3652         is an undocumented synonym.
3653
3654 2001-12-22  Akim Demaille  <akim@epita.fr>
3655
3656         * src/output.c (output_table_data): Change the prototype to use
3657         `int' for array ranges: some invocations do pass an int, not a
3658         short.

3684

3781         Make `make distcheck' work.
3782

3786 2001-12-15  Akim Demaille  <akim@epita.fr>
3787
3788         * src/nullable.c (set_nullable): Useless rules must be skipped,
3789         otherwise, since we range over their symbols, we might look at a
3790         nonterminal which no longer ``exists'', i.e., it is not counted in

3802         defines_obstack: its content can be found in the `stype' muscle
3803         anyway.
3804         (output_token_translations): Merge into...
3805         (symbols_output): this.
3806         Rename as...
3807         (symbols_save): this.
3808         (reader): Adjust.
3809         * src/output.c (header_output): New.
3810         (output): Call it.
3811
3812 2001-12-15  Akim Demaille  <akim@epita.fr>
3813
3814         * src/reader.c (parse_union_decl): Instead of handling two obstack
3815         simultaneously, use one to define the `stype' muscle, and use the
3816         value of the latter to fill defines_obstack.
3817         (copy_comment): Remove.
3818         (copy_comment2): Work for a single obstack.
3819         Rename as...
3820         (copy_comment): this.
3821
3822 2001-12-15  Akim Demaille  <akim@epita.fr>
3823
3824         * src/lex.c, src/lex.h (xgetc): No longer static.
3825         * src/reader.c (parse_union_decl): Revamp.
3826
3827 2001-12-15  Akim Demaille  <akim@epita.fr>
3828
3829         Still making progress in separating Bison into (i) input, (ii)
3830         process, (iii) output: now we can directly output the parser file
3831         without using table_obstack at all.
3832
3833         * src/files.c, src/files.h (table_obstack): Bye bye.
3834         (parser_file_name): New.
3835         * src/files.c (compute_output_file_names): Compute it.
3836         * src/output.c (actions_output, output_parser)
3837         (output_master_parser): To a file instead of an obstack.
3838
3839 2001-12-15  Akim Demaille  <akim@epita.fr>
3840
3841         Attach actions to rules, instead of pre-outputting them to
3842         actions_obstack.
3843
3844         * src/gram.h (rule_t): action and action_line are new members.
3845         * src/reader.c (symbol_list): Likewise.
3846         (copy_action): Save the actions within the rule.
3847         (packgram): Save them in rule_table.
3848         * src/output.c (actions_output): New.
3849         (output_parser): Use it on `%%actions'.
3850         (output_rule_data): Don't free rule_table.
3851         (output): Do it.
3852         (prepare): Don't save the `action' muscle.
3853         * src/bison.simple: s/%%action/%%actions/.
3854
3855 2001-12-15  Akim Demaille  <akim@epita.fr>
3856
3857         * src/reader.c (copy_action): When --yacc, don't append a `;'
3858         to the user action: let it fail if lacking.
3859         Suggested by Arnold Robbins and Tom Tromey.
3860
3861 2001-12-14  Akim Demaille  <akim@epita.fr>
3862
3863         * src/lex.c (literalchar): Simply return the char you decoded, non
3864         longer mess around with obstacks and int pointers.
3865         Adjust all callers.
3866
3867 2001-12-14  Akim Demaille  <akim@epita.fr>
3868
3869         * src/lex.c (literalchar): Don't escape the special characters,
3870         just decode them, and keep them as char (before, eol was output as
3871         the 2 char string `\n' etc.).
3872         * src/output.c (output_rule_data): Use quotearg to output the
3873         token strings.
3874
3875 2001-12-13  Paul Eggert  <eggert@twinsun.com>
3876
3877         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3878         Do not infringe on the global user namespace when using C++.
3879         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3880         All uses of `fprintf' and `stderr' changed.
3881
3882         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3883
3884 2001-12-13  Akim Demaille  <akim@epita.fr>
3885
3886         The computation of nullable is broken: it doesn't handle empty
3887         RHS's properly.
3888
3889         * tests/torture.at (GNU AWK Grammar): New.
3890         * tests/sets.at (Nullable): New.
3891         * src/nullable.c (set_nullable): Instead of blindly looping over
3892         `ritems', loop over the rules, and then over their rhs's.
3893
3894         Work around Autotest bugs.
3895
3896         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3897         frame, because Autotest understand lines starting with a `+' as
3898         traces from the shell.  Then, they are not processed properly.
3899         Admittedly an Autotest bug, but we don't have time to wait for
3900         Autotest to catch up.
3901         * tests/regression.at (Broken Closure): Adjust to the new table
3902         frames.
3903         Move to...
3904         * tests/sets.at: here.
3905
3906 2001-12-13  Akim Demaille  <akim@epita.fr>
3907
3908         * src/closure.c (closure): Use nrules instead of playing tricks
3909         with BITS_PER_WORD.
3910
3911 2001-12-13  Akim Demaille  <akim@epita.fr>
3912
3913         * src/print.c (print_actions): Output the handling of `$' as the
3914         traces do: shifting the token EOF.  Before EOF was treated as a
3915         nonterminal.
3916         * tests/regression.at: Adjust some tests.
3917         * src/print_graph.c (print_core): Complete the set of items via
3918         closure.  The next-to-final and final states are still unsatisfying,
3919         but that's to be addressed elsewhere.
3920         No longer output the rule numbers, but do output the state number.
3921         A single loop for the shifts + gotos is enough, but picked a
3922         distinct color for each.
3923         (print_graph): Initialize and finalize closure.
3924
3925 2001-12-13  Akim Demaille  <akim@epita.fr>
3926
3927         * src/reader.c (readgram): Remove dead code, an strip useless
3928         braces.
3929         (get_type): Remove, unused.
3930
3931 2001-12-12  Akim Demaille  <akim@epita.fr>
3932
3933         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3934         on that of lib/error.c.
3935
3936 2001-12-12  Akim Demaille  <akim@epita.fr>
3937
3938         Some hosts don't like `/' in includes.
3939
3940         * src/system.h: Include libgettext.h without qualifying the path.
3941         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3942         $(top_srcdir).
3943
3944 2001-12-11  Marc Autret  <autret_m@epita.fr>
3945
3946         * src/output.c (output_parser): Remove useless muscle.
3947
3948 2001-12-11  Marc Autret  <autret_m@epita.fr>
3949
3950         * src/bison.simple: Remove #line just before %%epilogue. It
3951         is now handled in ...
3952         * src/reader.c (read_additionnal_code): Add the output of a
3953         #line for the epilogue.
3954
3955 2001-12-10  Marc Autret  <autret_m@epita.fr>
3956
3957         * src/reader.c (copy_definition): Re-use CPP-outed code which
3958         replace precedent remove.
3959         * src/bison.simple: Remove #line before %%prologue because
3960         %%input-line is wrong at this time.
3961
3962 2001-12-10  Marc Autret  <autret_m@epita.fr>
3963
3964         * src/reader.c (symbols_output): Clean up.
3965         * src/output.c (output_gram, output): Clean up.
3966
3967 2001-12-10  Akim Demaille  <akim@epita.fr>
3968
3969         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
3970         * src/LR0.c (set_state_table): here.
3971         * src/lalr.c (lalr): Call it.
3972
3973 2001-12-10  Akim Demaille  <akim@epita.fr>
3974
3975         * src/state.h (shifts): Remove the `number' member: shifts are
3976         attached to state, hence no longer need to be labelled with a
3977         state number.
3978
3979 2001-12-10  Akim Demaille  <akim@epita.fr>
3980
3981         Now that states have a complete set of members, the linked list of
3982         shifts is useless: just fill directly the state's shifts member.
3983
3984         * src/state.h (shifts): Remove the `next' member.
3985         * src/LR0.c (first_state, last_state): Remove.
3986         Adjust the callers.
3987         (augment_automaton): Don't look for the shifts that must be added
3988         a shift on EOF: it is those of the state we looked for!  But now,
3989         since shifts are attached, it is no longer needed to looking
3990         merely by its id: its number.
3991
3992 2001-12-10  Akim Demaille  <akim@epita.fr>
3993
3994         * src/LR0.c (augment_automaton): Better variable locality.
3995         Remove an impossible branch: if there is a state corresponding to
3996         the start symbol being shifted, then there is shift for the start
3997         symbol from the initial state.
3998
3999 2001-12-10  Akim Demaille  <akim@epita.fr>
4000
4001         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4002         only when appropriate: when insert_start_shifting_state' is not
4003         invoked.
4004         * tests/regression.at (Rule Line Numbers): Adjust.
4005
4006 2001-12-10  Akim Demaille  <akim@epita.fr>
4007
4008         * src/LR0.c (augment_automaton): Now that all states have shifts,
4009         merge the two cases addition shifts to the initial state.
4010
4011 2001-12-10  Akim Demaille  <akim@epita.fr>
4012
4013         * src/lalr.c (set_state_table): Move to...
4014         * src/LR0.c: here.
4015         * src/lalr.c (lalr): Don't call it...
4016         * src/LR0.c (generate_states): do it.
4017         * src/LR0.h (first_state): Remove, only the table is used.
4018
4019 2001-12-10  Akim Demaille  <akim@epita.fr>
4020
4021         * src/LR0.h (first_shift, first_reduction): Remove.
4022         * src/lalr.c: Don't use first_shift: find shifts through the
4023         states.
4024
4025 2001-12-10  Akim Demaille  <akim@epita.fr>
4026
4027         * src/LR0.c: Attach shifts to states as soon as they are
4028         computed.
4029         * src/lalr.c (set_state_table): Instead of assigning shifts to
4030         state, just assert that the mapping was properly done.
4031
4032 2001-12-10  Akim Demaille  <akim@epita.fr>
4033
4034         * src/LR0.c (insert_start_shift): Rename as...
4035         (insert_start_shifting_state): this.
4036         (insert_eof_shifting_state, insert_accepting_state): New.
4037         (augment_automaton): Adjust.
4038         Better locality of the variables.
4039         When looking if the start_symbol is shifted from the initial
4040         state, using `while (... symbol != start_symbol ...)' sounds
4041         better than `while (... symbol < start_symbol ...)': If fail
4042         to see how the order between symbols could be relevant!
4043
4044 2001-12-10  Akim Demaille  <akim@epita.fr>
4045
4046         * src/getargs.h: Don't declare `spec_name_prefix' and
4047         `spec_file_prefix', declared by src/files.h.
4048         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4049         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4050         * src/output.c (prepare): Adjust.
4051         * src/reader.c (symbols_output): Likewise.
4052         * src/vmsgetargs.c: Vaguely adjust, but who cares?
4053
4054 2001-12-10  Akim Demaille  <akim@epita.fr>
4055
4056         * src/muscle_tab.c (muscle_init): NULL is a better default than
4057         `"0"'.
4058
4059 2001-12-10  Akim Demaille  <akim@epita.fr>
4060
4061         * src/reader.c (reader): Calling symbols_output once is enough.
4062
4063 2001-12-10  Akim Demaille  <akim@epita.fr>
4064
4065         Now that states have a complete set of members, the linked list of
4066         reductions is useless: just fill directly the state's reductions
4067         member.
4068
4069         * src/state.h (struct reductions): Remove member `number' and
4070         `next'.
4071         * src/LR0.c (first_reduction, last_reduction): Remove.
4072         (save_reductions): Don't link the new reductions, store them in
4073         this_state.
4074         * src/lalr.c (set_state_table): No need to attach reductions to
4075         states, it's already done.
4076         * src/output.c (output_actions): No longer free the shifts, then
4077         the reductions, then the states: free all the states and their
4078         members.
4079
4080 2001-12-10  Akim Demaille  <akim@epita.fr>
4081
4082         * src/options.c (OPTN, DRTV, BOTH): New.
4083         (option_table): Use them.
4084
4085         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4086         the job of system.h.
4087         * src/options.c: Don't include stdio.h and xalloc.h for the same
4088         reasons.
4089
4090 2001-12-10  Akim Demaille  <akim@epita.fr>
4091
4092         * src/output.c (output, prepare): Make sure the values of the
4093         muscles `action' and `prologue' are 0-terminated.
4094
4095 2001-12-10  Akim Demaille  <akim@epita.fr>
4096
4097         Clean up GCC warnings.
4098
4099         * src/reader.c (copy_action): `buf' is not used.
4100         (parse_skel_decl): Be static.
4101         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
4102         * src/options.h (create_long_option_table): Have a real prototype.
4103         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
4104         (hash_delete_at): Return const void *.
4105         Adjust casts to preserve the const.
4106
4107 2001-12-10  Akim Demaille  <akim@epita.fr>
4108
4109         * configure.in: Require 2.52g.
4110         M4 is not needed, but AUTOM4TE is.
4111         * m4/m4.m4: Remove.
4112         * tests/Makefile.am: Adjust.
4113
4114 2001-12-10  Akim Demaille  <akim@epita.fr>
4115
4116         One structure for states is enough, even though theoretically
4117         there are LR(0) states and LALR(1) states.
4118
4119         * src/lalr.h (state_t): Remove.
4120         (state_table): Be state_t **, not state_t *.
4121         * src/state.h (core, CORE_ALLOC): Rename as...
4122         (state_t, STATE_ALLOC): this.
4123         Add the LALR(1) members: shifts, reductions, errs.
4124         * src/LR0.c (state_table): Rename as...
4125         (state_hash): this, to avoid name clashes with the global
4126         `state_table'.
4127         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4128         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

4132         Bison dumps core on bash.y.
4133         Reported by Pascal Bart.
4134
4135         * src/warshall.c (bitmatrix_print): New.
4136         (TC): Use it.
4137         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4138         j must be the outer loop.

4153         (state_t.reductions, state_t.shifts): this.
4154
4155 2001-12-05  Akim Demaille  <akim@epita.fr>
4156
4157         * src/reduce.c (reduce_grammar_tables): No longer disable the
4158         removal of useless rules via CPP but via `if (0)', so that the
4159         compiler still check the code is valid.
4160         For instance, it should have noticed `rline' no longer exists: use
4161         the `line' member of rule_t.
4162         * src/gram.c (dummy, rline): Remove, unused.
4163
4164 2001-12-05  Akim Demaille  <akim@epita.fr>
4165
4166         * src/output.c (pack_vector): Use assert, not berror.
4167         * src/main.c (berror): Remove, unused.
4168
4169 2001-12-05  Akim Demaille  <akim@epita.fr>
4170
4171         New experimental feature: if --verbose --trace output all the
4172         items of a state, not only its kernel.
4173
4174         * src/print.c (print_core): If `trace_flag', then invoke closure
4175         before outputting the items of the state (print_core is no longer
4176         a correct name them).
4177         (print_results): Invoke new_closure/free_closure if needed.
4178
4179 2001-12-05  Akim Demaille  <akim@epita.fr>
4180
4181         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4182         * src/closure.c, src/closure.h (itemsetsize): Rename as...
4183         (nitemset): for consistency with the rest of the project.
4184
4185 2001-12-05  Akim Demaille  <akim@epita.fr>
4186
4187         * src/closure.c (print_closure): Improve.
4188         (closure): Use it for printing input and output.
4189
4190 2001-12-05  Akim Demaille  <akim@epita.fr>
4191
4192         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4193         indexed by nonterminals.
4194
4195 2001-12-05  Akim Demaille  <akim@epita.fr>
4196
4197         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4198         what it was!).
4199         * src/warshall.h: Remove accidental duplication of the content.
4200
4201 2001-12-05  Akim Demaille  <akim@epita.fr>
4202
4203         * src/closure.c (set_fderives): De-obfuscate.
4204
4205 2001-12-05  Akim Demaille  <akim@epita.fr>
4206
4207         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
4208
4209 2001-12-05  Akim Demaille  <akim@epita.fr>
4210
4211         * src/closure.c (set_firsts): De-obfuscate.
4212
4213 2001-12-05  Akim Demaille  <akim@epita.fr>
4214
4215         * src/output.c (action_row): De-obfuscate
4216         using the good o' techniques: arrays not pointers, variable
4217         locality, BITISSET, RESETBIT etc.
4218
4219 2001-12-05  Akim Demaille  <akim@epita.fr>
4220
4221         Pessimize the code to simplify it: from now on, all the states
4222         have a valid SHIFTS, which NSHIFTS is possibly 0.
4223
4224         * src/LR0.c (shifts_new): Be global and move to..
4225         * src/state.c, src/state.h: here.
4226         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4227         * src/print_graph: Adjust.
4228
4229 2001-12-05  Akim Demaille  <akim@epita.fr>
4230
4231         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4232         * src/conflicts.c: Use it.
4233         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4234         incorrectly ``simplified''.
4235
4236 2001-12-05  Akim Demaille  <akim@epita.fr>
4237
4238         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4239         using the good o' techniques: arrays not pointers, variable
4240         locality, BITISSET, RESETBIT etc.
4241
4242 2001-12-05  Akim Demaille  <akim@epita.fr>
4243
4244         * src/state.h (SHIFT_SYMBOL): New.
4245         * src/conflicts.c: Use it to deobfuscate.
4246
4247 2001-12-05  Akim Demaille  <akim@epita.fr>
4248
4249         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4250         (print_reductions): De-obfuscate using the good o' techniques:
4251         arrays not pointers, variable locality, BITISSET.
4252
4253 2001-12-05  Akim Demaille  <akim@epita.fr>
4254
4255         * src/conflicts.c (print_reductions): Arrays, not pointers.
4256         Use BITISSET.
4257
4258 2001-12-05  Akim Demaille  <akim@epita.fr>
4259
4260         * src/conflicts.c (print_reductions): Pessimize, but clarify.
4261
4262 2001-12-05  Akim Demaille  <akim@epita.fr>
4263
4264         * src/conflicts.c (print_reductions): Improve variable locality.
4265
4266 2001-12-05  Akim Demaille  <akim@epita.fr>
4267
4268         * src/conflicts.c (print_reductions): Pessimize, but clarify.
4269
4270 2001-12-05  Akim Demaille  <akim@epita.fr>
4271
4272         * src/conflicts.c (print_reductions): Improve variable locality.
4273
4274 2001-12-05  Akim Demaille  <akim@epita.fr>
4275
4276         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
4277         * src/lalr.c: Use them.
4278
4279 2001-12-05  Akim Demaille  <akim@epita.fr>
4280
4281         * src/LR0.c (augment_automaton): Formatting changes.
4282         Better variable locality.
4283
4284 2001-12-05  Akim Demaille  <akim@epita.fr>
4285
4286         * src/lalr.c (matrix_print): New.
4287         (transpose): Use it.
4288         Use arrays instead of pointers.
4289
4290 2001-12-05  Akim Demaille  <akim@epita.fr>
4291
4292         * src/lalr.c (maxrhs): Move to...
4293         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4294         * src/lalr.c (build_relations): Adjust.
4295
4296 2001-12-05  Akim Demaille  <akim@epita.fr>
4297
4298         * src/lalr.c (transpose): Free the memory allocated to the
4299         argument, as it is replaced by the results by the unique caller.
4300         (build_relations): Merely invoke transpose: it handles the memory
4301         deallocation.
4302         Improve variable locality.
4303         Avoid variables used as mere abbreviations.
4304         (compute_lookaheads): Use arrays instead of pointers.
4305
4306 2001-12-05  Akim Demaille  <akim@epita.fr>
4307
4308         * src/lalr.c (initialize_F): Improve variable locality.
4309         Avoid variables used as mere abbreviations.
4310
4311 2001-12-05  Akim Demaille  <akim@epita.fr>
4312
4313         * src/derives.c (print_derives): Display the ruleno.
4314         * src/lalr.c (initialize_F, transpose): Better variable locality
4315         to improve readability.
4316         Avoid variables used as mere abbreviations.
4317
4318 2001-12-05  Akim Demaille  <akim@epita.fr>
4319
4320         * src/lalr.c (traverse): Use arrays instead of pointers.
4321
4322 2001-12-05  Akim Demaille  <akim@epita.fr>
4323
4324         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4325         the handling of squeue.
4326         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4327
4328 2001-12-05  Akim Demaille  <akim@epita.fr>
4329
4330         Because useless nonterminals are now kept alive (instead of being
4331         `destroyed'), we now sometimes examine them, and store information
4332         related to them.  Hence we need to know their number, and adjust
4333         memory allocations.
4334
4335         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4336         static.
4337         * src/LR0.c (allocate_itemsets): The memory allocated to
4338         `symbol_count' was used for two different purpose: once to count
4339         the number of occurrences of each symbol, and later reassigned to
4340         `shift_symbol', containing the symbol that can be shifted from a
4341         given state.
4342         Deobfuscate, i.e., allocate, use and free `symbol_count' here
4343         only, and...
4344         (new_itemsets): Allocate `shift_symbol' here.
4345         (allocate_itemsets): symbol_count includes useless nonterminals.
4346         Make room for them.
4347         (free_storage): Use `free', not `XFREE', for pointers that cannot
4348         be null.
4349
4350 2001-12-05  Akim Demaille  <akim@epita.fr>
4351
4352         * src/nullable.c (set_nullable): Deobfuscate the handling of
4353         ritem.
4354         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4355
4356 2001-12-05  Akim Demaille  <akim@epita.fr>
4357
4358         * src/gram.c, src/gram.h (ritem_print): New.
4359         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4360         (This useless function was defined only to work around VMS linkers
4361         that can't handle compilation units with variables only).
4362         * src/reduce.c (dump_grammar): Use it to trace the construction of
4363         ritem.
4364
4365 2001-12-04  Paul Eggert  <eggert@twinsun.com>
4366
4367         * src/bison.simple (union yyalloc): Change member names
4368         to be the same as the stack names.
4369         (yyparse): yyptr is now union yyalloc *, not char *.
4370         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
4371         and may generate better code on some machines.
4372         (yystpcpy): Use prototype if __STDC__ is defined, not just
4373         if __cplusplus is defined.
4374
4375 2001-11-30  Akim Demaille  <akim@epita.fr>
4376
4377         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4378         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4379         Gettext doesn't compile cleanly, and dies with -Werror.
4380         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4381         Include WARNING_CFLAGS here.
4382         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4383         before being defined.
4384
4385 2001-11-27  Paul Eggert  <eggert@twinsun.com>
4386
4387         * lib/quotearg.h (quotearg_n, quotearg_n_style):
4388         First arg is int, not unsigned.
4389         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4390         (SIZE_MAX, UINT_MAX): New macros.
4391         (quotearg_n_options): Abort if N is negative.
4392         Avoid overflow check on hosts where size_t is 64 bits and int
4393         is 32 bits, as overflow is impossible there.
4394         Fix off-by-one typo that caused unnecessary reallocation.
4395
4396 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4397
4398         Name space cleanup in generated parser.
4399
4400         * doc/bison.texinfo (Bison Parser): Discuss system headers
4401         and their effect on the user name space.
4402
4403         * src/bison.simple:
4404         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4405         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4406         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4407
4408         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
4409         on user names when possible.
4410
4411         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4412         Simplify test for whather <alloca.h> exists.
4413
4414         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4415
4416         (<stdio.h>): Include if YYDEBUG.
4417
4418         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
4419         ! defined (yyoverflow) && ! defined (yymemcpy).
4420
4421         (yymemcpy, yyparse): Rename local variables as needed so that
4422         they all begin with 'yy'.
4423
4424         (yystrlen, yystpcpy): New functions.
4425
4426         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4427         All uses changed.
4428
4429         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
4430         instead of relying on string.h functions.  Use YYSTACK_ALLOC
4431         and YYSTACK_FREE instead of malloc and free.
4432
4433 2001-11-30  Akim Demaille  <akim@epita.fr>
4434
4435         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4436         before their first uses.
4437         (YYBISON, YYPURE): Move to the top of the output.
4438
4439 2001-11-30  Akim Demaille  <akim@epita.fr>
4440
4441         * tests/reduce.at (Useless Nonterminals): Fix.
4442
4443 2001-11-30  Akim Demaille  <akim@epita.fr>
4444
4445         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4446         if body instead of `;' to pacify GCC's warnings.
4447
4448 2001-11-30  Akim Demaille  <akim@epita.fr>
4449
4450         Instead of mapping the LHS of unused rules to -1, keep the LHS
4451         valid, but flag the rules as invalid.
4452
4453         * src/gram.h (rule_t): `useful' is a new member.
4454         * src/print.c (print_grammar): Adjust.
4455         * src/derives.c (set_derives): Likewise.
4456         * src/reader.c (packgram, reduce_output): Likewise.
4457         * src/reduce.c (reduce_grammar_tables): Likewise.
4458         * tests/reduce.at (Underivable Rules, Useless Rules): New.
4459
4460 2001-11-30  Akim Demaille  <akim@epita.fr>
4461
4462         * src/reduce.c (reduce_output): Formatting changes.
4463         * src/print.c (print_results, print_grammar): Likewise.
4464         * tests/regression.at (Rule Line Numbers)
4465         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4466
4467 2001-11-30  Akim Demaille  <akim@epita.fr>
4468
4469         * src/reduce.c (nonterminals_reduce): Instead of throwing away
4470         useless nonterminals, move them at the end of the symbol arrays.
4471         (reduce_output): Adjust.
4472         * tests/reduce.at (Useless Nonterminals): Adjust.
4473
4474 2001-11-30  Akim Demaille  <akim@epita.fr>
4475
4476         * src/reduce.c: Various comment/formatting changes.
4477         (nonterminals_reduce): New, extracted from...
4478         (reduce_grammar_tables): here.
4479         (reduce_grammar): Call nonterminals_reduce.
4480
4481 2001-11-29  Paul Eggert  <eggert@twinsun.com>
4482
4483         * src/bison.simple (YYSTACK_REALLOC): Remove.
4484         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4485         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4486         New macros.
4487         (union yyalloc): New type.
4488         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4489         an arbitrary restriction on hosts where size_t is wider than int.
4490
4491         (yyparse): Don't dump core if alloca or malloc fails; instead, report
4492         a parser stack overflow.  Allocate just one block of memory for all
4493         three stacks, instead of allocating three blocks; this typically is
4494         faster and reduces fragmentation.
4495
4496         Do not limit the number of items in the stack to a value that fits
4497         in 'int', as this is an arbitrary limit on hosts with 64-bit
4498         size_t and 32-bit int.
4499
4500 2001-11-29  Marc Autret  <autret_m@epita.fr>
4501
4502         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4503         of defining YYERROR_VERBOSE.
4504         [AT_DATA]: $4 is now out of C declarations in the prologue.
4505
4506 2001-11-28  Marc Autret  <autret_m@epita.fr>
4507
4508         * src/reader.c (parse_dquoted_param): New.
4509         (parse_skel_decl): Use it.
4510         * src/lex.h: Add its prototype.
4511         * src/lex.c (literalchar): Become not static.

4926         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
4927         now the tests are run in private dirs, therefore AC_CLEANUP and

4929         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,

4950         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
4951         Revert a previous patch:  these are really const.

4955         arg_offset.

4958         token_buffer not to change.

5054         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
5055         with yyltype/YYLTYPE.  This allows inclusion of the generated

6293         * src/getargs.c (longopts): Clean up.
6294
6295 2001-02-21  Akim Demaille  <akim@epita.fr>
6296
6297         * src/reader.c (gensym): `gensym_count' is your own.
6298         Use a static buf to create the symbol name, as token_buffer is no
6299         longer a buffer.
6300
6301 2001-02-08  Akim Demaille  <akim@epita.fr>
6302
6303         * src/conflicts.c (conflict_report): Be sure not to append to res
6304         between two calls, which could happen if both first sprintf were
6305         skipped, but not the first cp += strlen.
6306
6307 2001-02-08  Akim Demaille  <akim@epita.fr>
6308
6309         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
6310         New, from fileutils 4.0.37.
6311         * configure.in: Require Autoconf 2.49c.  I took some time before
6312         making this decision.  This is the only way out for portability
6313         issues in Bison, it would mean way too much duplicate effort to
6314         import in Bison features implemented in 2.49c since 2.13.
6315         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
6316
6317 2001-02-02  Akim Demaille  <akim@epita.fr>
6318
6319         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.
6320         * lib/xalloc.h, lib/xmalloc.c: Update.
6321
6322 2001-01-19  Akim Demaille  <akim@epita.fr>
6323
6324         Get rid of the ad hoc handling of token_buffer in the scanner: use
6325         the obstacks.
6326
6327         * src/lex.c (token_obstack): New.
6328         (init_lex): Initialize it.  No longer call...
6329         (grow_token_buffer): this.  Remove it.
6330         Adjust all the places which used it to use the obstack.
6331
6332 2001-01-19  Akim Demaille  <akim@epita.fr>
6333
6334         * src/lex.h: Rename all the tokens:
6335         s/\bENDFILE\b/tok_eof/g;
6336         s/\bIDENTIFIER\b/tok_identifier/g;
6337         etc.
6338         Let them be enums, not #define, to ease debugging.
6339         Adjust all the code.
6340
6341 2001-01-18  Akim Demaille  <akim@epita.fr>
6342
6343         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
6344         * src/lex.c (maxtoken, grow_token_buffer): Static.
6345
6346 2001-01-18  Akim Demaille  <akim@epita.fr>
6347
6348         Since we now use obstacks, more % directives can be enabled.
6349
6350         * src/lex.c (percent_table): Also accept `%yacc',
6351         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
6352         `%debug'.
6353         Handle the actions for `%semantic_parser' and `%pure_parser' here,
6354         instead of returning a token.
6355         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
6356         * src/reader.c (read_declarations): Adjust.
6357         * src/files.c (open_files): Don't call `compute_base_names', don't
6358         compute `attrsfile' since they depend upon data which might be
6359         *in* the input file now.
6360         (output_files): Do it here.
6361         * src/output.c (output_headers): Document the fact that this patch
6362         introduces a guaranteed SEGV for semantic parsers.
6363         * doc/bison.texinfo: Document them.
6364         * tests/suite.at: Exercise these %options.
6365
6366 2000-12-20  Akim Demaille  <akim@epita.fr>
6367
6368         Also handle the output file (--verbose) with obstacks.
6369
6370         * files.c (foutput): Remove.
6371         (output_obstack): New.
6372         Adjust all dependencies.
6373         * src/conflicts.c: Return a string.
6374         * src/system.h (obstack_grow_string): Rename as...
6375         (obstack_sgrow): this.  Be ready to work with non literals.
6376         (obstack_fgrow4): New.
6377
6378 2000-12-20  Akim Demaille  <akim@epita.fr>
6379
6380         * src/files.c (open_files): Fix the computation of short_base_name
6381         in the case of `-o foo.tab.c'.
6382
6383 2000-12-20  Akim Demaille  <akim@epita.fr>
6384
6385         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
6386         (copy_dollar): Now that everything uses obstacks, get rid of the
6387         FILE * parameters.
6388
6389 2000-12-20  Akim Demaille  <akim@epita.fr>
6390
6391         * src/files.c (open_files): Actually the `.output' file is based
6392         on the short_base_name, not base_name.
6393         * tests/suite.at (Checking output file names): Adjust.
6394
6395 2000-12-20  Akim Demaille  <akim@epita.fr>
6396
6397         * src/bison.s1: Remove, we now use directly...
6398         * src/bison.simple: this.
6399         * src/Makefile.am: Use pkgdata instead of data.
6400
6401 2000-12-20  Akim Demaille  <akim@epita.fr>

6412         vars.
6413         (open_files): Don't compute them.
6414         (output_files): Adjust.
6415         (base_name, short_base_name): Be global.
6416         Adjust dependencies.
6417
6418 2000-12-19  Akim Demaille  <akim@epita.fr>
6419
6420         * src/files.c (strsuffix): New.
6421         (stringappend): Be just like strcat but allocate.
6422         (base_names): Eve out from open_files.
6423         Try to simplify the rather hairy computation of base_name and
6424         short_base_name.
6425         (open_files): Use it.
6426         * tests/suite.at (Checking output file names): New test.
6427
6428 2000-12-19  Akim Demaille  <akim@epita.fr>

6431         (obstack_grow_string): this.
6432         * src/output.c (output_parser): Recognize `%% actions' instead of
6433         `$'.
6434         * src/bison.s1: s/$/%% actions/.
6435         * src/bison.hairy: Likewise.
6436
6437 2000-12-19  Akim Demaille  <akim@epita.fr>
6438
6439         * src/output.c (output_parser): Compute the `#line' lines when
6440         there are.
6441         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
6442         Suggested by Hans Aberg.
6443
6444 2000-12-19  Akim Demaille  <akim@epita.fr>
6445
6446         Let the handling of the skeleton files be local to the procedures
6447         that use it.
6448
6449         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
6450         longer static.
6451         (fparser, open_extra_files): Remove.
6452         (open_files, output_files): Don't take care of fparser.
6453         * src/files.h: Adjust.

6458
6459 2000-12-19  Akim Demaille  <akim@epita.fr>
6460

6462         * src/system.h (BISON_SIMPLE, BISON_HAIRY): ... to here.
6463
6464 2000-12-19  Akim Demaille  <akim@epita.fr>
6465
6466         * src/files.c (open_files): Yipee!  We no longer need all the code
6467         looking for `/tmp' since we have no tmp file.
6468
6469 2000-12-19  Akim Demaille  <akim@epita.fr>
6470
6471         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
6472         New macros.
6473         * src/files.c (open_files): Less dependency on MSDOS etc.

6497
6498         * lib/obstack.h: Formatting changes.
6499         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6500         prevents type checking.
6501         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6502         cast the value to (void *): assigning a `foo *' to a `void *'
6503         variable is valid.
6504         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
6505         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6519
6520 2000-11-17  Akim Demaille  <akim@epita.fr>
6521
6522         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
6523         macros.

6540
6541 2000-11-07  Akim Demaille  <akim@epita.fr>
6542
6543         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
6544         Merge in a single CPP if/else.
6545
6546 2000-11-07  Akim Demaille  <akim@epita.fr>
6547
6548         * src/output.c (output): Remove useless variables.
6549         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
6550         argument `data' for consistency with the prototypes.
6551         Qualify it `const'.
6552         (obstack_copy, obstack_copy0): Rename the second argument as
6553         `address' for consistency.  Qualify it `const'.
6554         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
6555         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
6556         `const' their input argument (`data' or `address').
6557         Adjust the corresponding macros to include `const' in casts.
6558
6559 2000-11-03  Akim Demaille  <akim@epita.fr>
6560
6561         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

6563         Adjust dependencies.
6564
6565 2000-11-03  Akim Demaille  <akim@epita.fr>
6566
6567         For some reason, this was not applied.
6568
6569         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

6573

6584         Use `obstack_save'.
6585         * src/main.c (main): Don't use `atexit' to register `done', since
6586         it no longer has to remove tmp files, just call `output_files'
6587         when there are no errors.
6588
6589 2000-11-02  Akim Demaille  <akim@epita.fr>
6590

6658         * src/reader.c (copy_comment2): Expect the input stream to be on
6659         the `/' which is suspected to open a comment, instead of being
6660         called after `//' or `/*' was read.
6661         (copy_comment, copy_definition, parse_union_decl, copy_action)
6662         (copy_guard): Adjust.

6692         When a literal string is used to define two different tokens,
6693         `bison -v' segfaults.
6694         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

6707 2000-10-02  Paul Eggert  <eggert@twinsun.com>
6708
6709         * bison.s1 (yyparse): Assign the default value
6710         unconditionally, to avoid a GCC warning and make the parser a
6711         tad smaller.
6712
6713 2000-10-02  Akim Demaille  <akim@epita.fr>
6714
6715         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

6719
6720         * src/derives.c, src/print.c, src/reduce.c: To ease the

6722
6723 2000-10-02  Akim Demaille  <akim@epita.fr>
6724
6725         The location tracking mechanism is precious for parse error
6726         messages.  Nevertheless, it is enabled only when `@n' is used in
6727         the grammar, which is a different issue (you can use it in error
6728         message, but not in the grammar per se).  Therefore, there should
6729         be another means to enable it.
6730
6731         * src/getargs.c (getargs): Support `--locations'.
6732         (usage): Report it.
6733         * src/getargs.h (locationsflag): Export it.
6734         * src/lex.c (percent_table): Support `%locations'.
6735         * src/reader.c (yylsp_needed): Remove this variable, now replaced
6736         with `locationsflag'.
6737         * doc/bison.texinfo: Document `--locations' and `%locations'.
6738         Sort the options.
6739         * tests/calc.m4: Test it.
6740
6741         For regularity of the names, replace each
6742         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6743         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6744         In addition replace each `flag' with `_flag'.
6745
6746 2000-10-02  Akim Demaille  <akim@epita.fr>
6747
6748         Also test parse error messages, including with YYERROR_VERBOSE.
6749
6750         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6751         associative).
6752         Use it to check the computations.
6753         Use it to check `nonassoc' is honored.
6754         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6755         `--yyerror-verbose'.
6756         (_AT_CHECK_CALC): Adjust to this option.
6757         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6758
6759 2000-10-02  Akim Demaille  <akim@epita.fr>
6760
6761         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
6762         the latter demonstrates a flaw in the handling of non debugging
6763         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6764         was used in order to simplify:
6765
6766         #if YYDEBUG
6767         if (yydebug)
6768         {
6769         ...
6770         }
6771         #endif
6772
6773         into
6774
6775         if (yydebug)
6776         {
6777         ...
6778         }
6779
6780         unfortunately this leads to a CPP conflict when
6781         `--name-prefix=foo' is used since it produces `#define yydebug
6782         foodebug'.
6783
6784         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6785         (YYDPRINTF): New macro.
6786         Spread its use.
6787         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6788         the bison options.
6789         Also test `--verbose', `--defines' and `--name-prefix'.
6790
6791 2000-10-02  Akim Demaille  <akim@epita.fr>
6792
6793         Improve the readability of the produced parsers.
6794
6795         * src/bison.s1: Formatting changes.
6796         Improve the comment related to the `$' mark.
6797         (yydefault): Don't fall through to `yyresume': `goto' there.
6798         * src/output.c (output_parser): When the `$' is met, skip the end
6799         of its line.
6800         New variable, `number_of_dollar_signs', to check there's exactly
6801         one `$' in the parser skeleton.
6802
6803 2000-10-02  Akim Demaille  <akim@epita.fr>
6804
6805         * lib/xstrdup.c: New file, from the fileutils.
6806         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6807         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6808         instead of strlen + xmalloc + strcpy.
6809         * src/symtab.c (copys): Remove, use xstrdup instead.
6810
6811 2000-10-02  Akim Demaille  <akim@epita.fr>
6812
6813         * src/gram.h (associativity): New enum type which replaces the
6814         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6815         `right_assoc', `left_assoc' and `non_assoc'.
6816         Adjust all dependencies.
6817         * src/reader.c: Formatting changes.
6818         (LTYPESTR): Don't define it, use it as a literal in
6819         `reader_output_yylsp'.
6820         * src/symtab.h (symbol_class): New enum type which replaces the
6821         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
6822         `sunknown', `stoken and `snterm'.
6823
6824 2000-10-02  Akim Demaille  <akim@epita.fr>
6825
6826         * src/getargs.c (fixed_outfiles): Rename as...
6827         (yaccflag): for consistency and accuracy.
6828         Adjust dependencies.
6829
6830 2000-10-02  Akim Demaille  <akim@epita.fr>
6831
6832         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6833         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
6834         difficult and introduced a lot of core dump.  It turns out that
6835         Bison used an implementation of `xmalloc' based on `calloc', and
6836         at various places it does depend upon the initialization to 0.  I
6837         have not tried to isolate the pertinent places, and all the former
6838         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
6839         someone should address this issue.
6840
6841         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
6842         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

6935
6936         * src/output.c (token_actions): Introduce a temporary array,

6938         output_short_table.
6939
6940 2000-10-02  Akim Demaille  <akim@epita.fr>
6941
6942         `user_toknums' is output as a `short[]' in `output.c', while it is
6943         defined as a `int[]' in `reader.c'.  For consistency with the
6944         other output tables, `user_toknums' is now defined as a table of
6945         shorts.
6946
6947         * src/reader.c (user_toknums): Be a short table instead of an int
6948         table.

6960         order to get rid of the `static' prototypes.
6961         No longer use `register'.
6962         * src/output.h: New file.
6963         Propagate its inclusion in files explicitly prototyping functions
6964         from output.c.

6986         inclusion.
6987         Don't define PARAMS.
6988         * src/system.h: Define PARAMS.
6989         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
6990         purpose of config.h.  system.h must not try to fix wrong

7128         * configure.in: Adjust.
7129         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

7153         the file name, not the whole `#line LINE FILE'.
7154
7155 2000-03-17  Akim Demaille  <akim@epita.fr>
7156
7157         On syntax errors, report the token on which we choked.
7158
7159         * src/bison.s1 (yyparse): In the label yyerrlab, when

7177

7179         copy_comment.  Removed now unused `match', `ended',
7180         `cplus_comment'.
7181         (copy_comment, copy_string): Moved, to be visible from
7182         copy_definition.
7183

7185
7186         * src/reader.c (copy_string): Declare `static inline'.  No

7208
7209         Change the handling of @s so that they behave exactly like $s.
7210         There is now a pseudo variable @$ (readble and writable), location
7211         of the lhs of the rule (by default ranging from the location of
7212         the first symbol of the rhs, to the location of the last symbol,
7213         or, if the rhs is empty, YYLLOC).
7214
7215         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7216         yyval.
7217         (yyparse): When providing a default semantic action, provide a
7218         default location action.
7219         (after the $): No longer change `*YYLSP', just stack YYLOC the
7220         same way you stack YYVAL.
7221         * src/reader.c (read_declarations): Use warns.
7222         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
7223         (copy_action, case '@'): Likewise.
7224         Use a standard error message, to save useless work from
7225         translators.
7226
7227 2000-03-17  Akim Demaille  <akim@epita.fr>
7228

7246
7247         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
7248         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7249         One `#if YYDEBUG' remains, since it uses variables which are
7250         defined only if `YYDEBUG != 0'.
7251
7252 2000-03-16  Akim Demaille  <akim@epita.fr>

7276         handled via src/Makefile.am.

7278         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

7284         the proper line number and file name.
7285         (DEFS): Propagate the location of bison library files and of the
7286         locale files.
7287         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7288         builddir.
7289         * acinclude.m4: Remove, replaced by the directory m4.
7290         * m4/Makefile.am (EXTRA_DIST): New variable.
7291         * m4/gettext.m4: New file, from the fileutils.

7978         major changes to files.c.
