PE		 62002-01-29 Paul Eggert <eggert@twinsun.com>
7
8 * src/bison.simple (YYSIZE_T): Do not define merely because
9 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
10 On some platforms, <alloca.h> does not declare YYSTD (size_t).

AD		 122002-01-27 Akim Demaille <akim@epita.fr>
13
14 Fix `%nonassoc and eof'.
15
16 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
17 which were not properly copied! Replace
18 memcpy (res->errs, src->errs, src->nerrs);
19 with
20 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
21 !!!
22 * tests/regression.at (%nonassoc and eof): Adjust to newest
23 Autotest: `.' is not in the PATH.
24
318b76e9
AD		 252002-01-27 Akim Demaille <akim@epita.fr>
26
27 * tests/sets.at (AT_EXTRACT_SETS): New.
28 (Nullable): Use it.
29 (Firsts): New.

32
33 * tests/actions.at, tests/calc.at, tests/headers.at,
34 * tests/torture.at: Adjust to the newest Autotest which no longer
35 forces `.' in the PATH.

44 Bison dumps core when trying to complain about broken input files.
45 Reported by Cris van Pelt.
46
47 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
48 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
49 into...
50 (Invalid inputs): Strengthen: exercise parse_percent_token.
51

RA		 522002-01-24 Robert Anisko <robert.anisko@epita.fr>

MA		 692002-01-20 Marc Autret <marc@gnu.org>
70
71 * tests/output.at: New test.
72 * src/files.c (compute_base_names): Don't map extensions when
73 the YACC flag is set, use defaults.
74 Reported by Evgeny Stambulchik.
75
44ea3fbd
MA		 762002-01-20 Marc Autret <marc@gnu.org>
77
bb0146c2 78 * src/system.h: Need to define __attribute__ away for non-GCC
44ea3fbd
MA		 79 compilers as well (i.e. the vendor C compiler).
80 Suggested by Albert Chin-A-Young.
81
338963d1
TVH		 822002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
83
84 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
85 canonical definition.
86 * src/system.h: Use the canonical definition for PARAMS (avoids
87 a conflict with the macro from lib/hash.h).
88
c57b2479
AD		 892002-01-11 Akim Demaille <akim@epita.fr>
90
91 * configure.in: Use AC_FUNC_STRNLEN.
d9e9746c 92 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.

AD		 942002-01-09 Akim Demaille <akim@epita.fr>
95
96 * src/files.c, src/files.h (output_infix): New.
97 (tab_extension): Remove.
98 (compute_base_names): Compute the former, drop the latter.
99 * src/output.c (prepare): Insert the muscles `output-infix', and
100 `output-suffix'.
101 * src/parse-skel.y (string, string.1): New.
102 (section.header): Use it.
103 (section.yacc): Remove.
104 (prefix): Remove too.

cae60122
AD		 1082002-01-09 Akim Demaille <akim@epita.fr>
109
110 * configure.in (WERROR_CFLAGS): Compute it.
111 * src/Makefile.am (CFLAGS): Pass it.
112 * tests/atlocal.in (CFLAGS): Idem.
113 * src/files.c: Fix a few warnings.
114 (get_extension_index): Remove, unused.
115
ae404801
AD		 1162002-01-08 Akim Demaille <akim@epita.fr>
117
118 * src/getargs.c (AS_FILE_NAME): New.
119 (getargs): Use it to convert DOSish file names.
120 * src/files.c (base_name): Rename as full_base_name to avoid
121 clashes with `base_name ()'.
122 (filename_split): New.
123 (compute_base_names): N-th rewrite, using filename_split.
124
22312b71
AD		 1252002-01-08 Akim Demaille <akim@epita.fr>
126
127 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
128 New, stolen from the Fileutils 4.1.
129 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
130 * configure.in: Check for the presence of memrchr, and of its
131 prototype.
132
a67cef01
TVH		 1332002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
134
135 * lib/hash.h (__P): Added definition for this macro.
136 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
137 BUILT_SOURCES, to ensure they are generated first.
138 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
139 %error-verbose to allow bootstrapping with bison 1.30x.
140
2b25d624
AD		 1412002-01-06 Akim Demaille <akim@epita.fr>
142
143 * src/reader.c (parse_braces): Don't fetch the next char, the
144 convention is to fetch on entry.
145 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
146 'switch' without a following semicolon.
147 * tests/regression.at (braces parsing): New.
148
3460813b
AD		 1492002-01-06 Akim Demaille <akim@epita.fr>
150
151 Bison is dead wrong in its RR conflict reports.
152
153 * tests/torture.at (GNU Cim Grammar): New.
154 * src/conflicts.c (count_rr_conflicts): Fix.
155
73784c64
AD		 1562002-01-06 Akim Demaille <akim@epita.fr>
157
158 Creating package.m4 from configure.ac causes too many problems.
159
160 * tests/Makefile.am (package.m4): Create it by hand,
161 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
162
25d81090
AD		 1632002-01-06 Akim Demaille <akim@epita.fr>
164
165 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
166 skeleton.h.
167
a9b8959e
PE		 1682002-01-04 Paul Eggert <eggert@twinsun.com>
169
170 * doc/bison.texinfo (Debugging):
171 Remove YYSTDERR; it's no longer defined or used.
172 Also, s/cstdio.h/cstdio/.
173
25d81090
AD		 1742002-01-03 Akim Demaille <akim@epita.fr>
175
176 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
177
1109455c
AD		 1782002-01-03 Akim Demaille <akim@epita.fr>
179
180 * src/parse-skel.y (process_skeleton): Don't bind the parser's
181 tracing code to --trace, wait for a better --trace option, with
182 args.
183
7ea5e977
AD		 1842002-01-03 Akim Demaille <akim@epita.fr>
185
186 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
187 The ISO C++ standard is extremely clear about it: stderr is
188 considered a macro, not a regular symbol (see table 94 `Header
189 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
190 Therefore std:: does not apply to it. It still does with fprintf.
191 Also, s/cstdio.h/cstdio/.
192
fab5b110
AD		 1932002-01-03 Akim Demaille <akim@epita.fr>
194
195 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
196 for non system headers.
197
aed7fd9b
AD		 1982002-01-02 Akim Demaille <akim@epita.fr>
199
200 Equip the skeleton chain with location tracking, runtime trace,
201 pure parser and scanner.
202
203 * src/parse-skel.y: Request a pure parser, locations, and prefix
204 renaming.
205 (%union): Having several members with the same type does not help
206 type mismatches, simplify.
207 (YYPRINT, yyprint): New.
208 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
209 (skel_error): this.
210 Handle locations.
211 * src/scan-skel.l: Adjust to these changes.
212 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
213 (LOCATION_PRINT, skel_control_t): New.
214
24fad99e
AD		 2152001-12-30 Akim Demaille <akim@epita.fr>
216
217 * src/parse-skel.y: Get rid of the shift/reduce conflict:
218 replace `gb' with BLANKS.
219 * src/scan-skel.l: Adjust.
220
a4b36db4
AD		 2212001-12-30 Akim Demaille <akim@epita.fr>
222
223 * src/system.h: We don't need nor want bcopy.
224 Throw away MS-DOS crap: we don't need getpid.
225 * configure.in: We don't need strndup. It was even causing
226 problems: because Flex includes the headers *before* us,
227 _GNU_SOURCE is not defined by config.h, and therefore strndup was
228 not visible.
229 * lib/xstrndup.c: New.
230 * src/scan-skel.l: Use it.
231 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
232 * src/parse-skel.y: Use %directives instead of #defines.
233
1239777d
AD		 2342001-12-30 Akim Demaille <akim@epita.fr>
235
236 * src/skeleton.h: New.
237 * src/output.c (output_parser, output_master_parser): Remove, dead
238 code.
239 * src/output.h (get_lines_number, actions_output, guards_output)
240 (token_definitions_output): Prototype them.
241 * src/parse-skel.y: Add the license notice.
242 Include output.h and skeleton.h.
243 (process_skeleton): Returns void, and takes a single parameter.
244 * src/scan-skel.l: Add the license notice.
245 Include skeleton.h.
246 Don't use %option yylineno: it seems that then Flex imagines
247 REJECT has been used, and therefore it won't reallocate its
248 buffers (which makes no other sense to me than a bug). It results
249 in warnings for `unused: yy_flex_realloc'.
250
9b3add5b
RA		 2512001-12-30 Robert Anisko <robert.anisko@epita.fr>
252
253 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
254 (MUSCLE_INSERT_PREFIX): ...to there.
255 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
256 (MUSCLE_INSERT_PREFIX): Move from here...
257
258 * src/bison.hairy: Add a section directive. Put braces around muscle
259 names. This parser skeleton is still broken, but Bison should not
260 choke on a bad muscle 'syntax'.
261 * src/bison.simple: Add a section directive. Put braces around muscle
262 names.
263
264 * src/files.h (strsuffix, stringappend): Add declarations.
265 (tab_extension): Add declaration.
266 (short_base_name): Add declaration.
267
268 * src/files.c (strsuffix, stringappend): No longer static. These
269 functions are used in the skeleton parser.
270 (tab_extension): New.
271 (compute_base_names): Use the computations done in this function
fab5b110 272 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA		 273 names.
274 (short_base_name): No longer static.
275
276 * src/output.c (output_skeleton): New.
277 (output): Disable call to output_master_parser, and give a try to
278 a new skeleton handling system.
279 (guards_output, actions_output): No longer static.
280 (token_definitions_output, get_lines_number): No longer static.
281
282 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
283
fab5b110 284 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA		 285 parse-skel.y.
286
287 * src/parse-skel.y: New file.
288 * src/scan-skel.l: New file.
289
b5b61c61
AD		 2902001-12-29 Akim Demaille <akim@epita.fr>
291
292 %name-prefix is broken.
293
294 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
295 Adjust all dependencies.
296 * tests/headers.at (export YYLTYPE): Strengthen this test: use
297 %name-prefix.
298
299 Renaming yylval but not yylloc is not consistent. Now we do.
300
301 * src/bison.simple: Prefix yylloc if used.
302 * doc/bison.texinfo (Decl Summary): Document that.
303
8c9a50be
AD		 3042001-12-29 Akim Demaille <akim@epita.fr>
305
306 * doc/bison.texinfo: Promote `%long-directive' over
307 `%long_directive'.
308 Remove all references to fixed-output-files, yacc is enough.
309
d99361e6
AD		 3102001-12-29 Akim Demaille <akim@epita.fr>
311
312 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
313 user prologue. These are defaults.
314 * tests/actions.at (Mid-rule actions): Make sure the user can
315 define YYDEBUG and YYERROR_VERBOSE.
316
b9cecb91
AD		 3172001-12-29 Akim Demaille <akim@epita.fr>
318
319 * src/output.c (header_output): Don't forget to export YYLTYPE and
320 yylloc.
321 * tests/headers.at (export YYLTYPE): New, make sure it does.
322 * tests/regression.at (%union and --defines, Invalid CPP headers):
323 Move to...
324 * tests/headers.at: here.
325
aea13e97
AD		 3262001-12-29 Akim Demaille <akim@epita.fr>
327
328 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
329
931394cb
AD		 3302001-12-29 Akim Demaille <akim@epita.fr>
331
332 * tests/actions.at (Mid-rule actions): Output on a single line
333 instead of several.
334
704a47c4
AD		 3352001-12-29 Akim Demaille <akim@epita.fr>
336
337 * doc/bison.texinfo: Formatting changes.
338
091e20bb
AD		 3392001-12-29 Akim Demaille <akim@epita.fr>
340
341 Don't store the token defs in a muscle, just be ready to output it
342 on command. Now possible via `symbols'. Fixes a memory leak.
343
344 * src/output.c (token_definitions_output): New.
345 (output_parser, header_output): Use it.
346 * src/reader.c (symbols_save): Remove.
347
cce71710
AD		 3482001-12-29 Akim Demaille <akim@epita.fr>
349
350 * src/bison.simple: Do not provide a default for YYSTYPE and
351 YYLTYPE before the user's prologue. Otherwise it's hardly... a
352 default.
353
82c035a8
AD		 3542001-12-29 Akim Demaille <akim@epita.fr>
355
356 Mid-rule actions are simply... ignored!
357
358 * src/reader.c (readgram): Be sure to attach mid-rule actions to
359 the empty-rule associated to the dummy symbol, not to the host
360 rule.
361 * tests/actions.at (Mid-rule actions): New.
362
8419d367
AD		 3632001-12-29 Akim Demaille <akim@epita.fr>
364
365 Memory leak.
366
367 * src/reader.c (reader): Free grammar.
368
375d5806
AD		 3692001-12-29 Akim Demaille <akim@epita.fr>
370
371 Memory leak.
372
373 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
374 since it allocates it for each state, although only one is needed.
375 (allocate_storage): Do it here.
376
f51cb8ff
AD		 3772001-12-29 Akim Demaille <akim@epita.fr>
378
379 * src/options.h, src/options.c (create_long_option_table): Rename
380 as...
381 (long_option_table_new): this, with a clearer prototype.
382 (percent_table): Remove, unused,
383 * src/getargs.c (getargs): Adjust.
384
29e88316
AD		 3852001-12-29 Akim Demaille <akim@epita.fr>

388 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
389 as states.
390
b9f71f19
AD		 3912001-12-29 Akim Demaille <akim@epita.fr>
392
393 * src/lalr.c (build_relations): Rename `states' as `states1'.
394 Sorry, I don't understand exactly what it is, no better name...
395
1a2b5d37
AD		 3962001-12-29 Akim Demaille <akim@epita.fr>
397
398 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
399 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
400 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
401 as rules.
402
1cca533e
AD		 4032001-12-29 Akim Demaille <akim@epita.fr>
404
405 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
406 ago.
407
c03ae966
AD		 4082001-12-29 Akim Demaille <akim@epita.fr>
409
410 * src/reader.c, src/reader.h (user_toknums): Remove.
411 Adjust all users to use symbols[i]->user_token_number.
412
5a670b1e
AD		 4132001-12-29 Akim Demaille <akim@epita.fr>
414
415 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
416 Adjust all users to use symbols[i]->prec or ->assoc.
417
ad949da9
AD		 4182001-12-29 Akim Demaille <akim@epita.fr>
419
420 * src/reader.c, src/reader.h (tags): Remove.
421 Adjust all users to use symbols[i]->tag.
422
0e78e603
AD		 4232001-12-29 Akim Demaille <akim@epita.fr>
424
425 * src/gram.h, src/gram.c (symbols): New, similar to state_table
426 and rule_table.
427 * src/reader.c (packsymbols): Fill this table.
428 Drop sprec.
429 * src/conflicts.c (resolve_sr_conflict): Adjust.
430 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
431 single table.
432 Use symbols[i]->tag instead of tags[i].
433
213e640e
AD		 4342001-12-29 Akim Demaille <akim@epita.fr>
435
436 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
437 In addition, put a comment in there, to replace...
438 * tests/regression.at (%union and C comments): Remove.
439
e7b8bef1
AD		 4402001-12-29 Akim Demaille <akim@epita.fr>
441
442 * tests/regression.at (Web2c Actions): Blindly move the actual
443 output as expected output. The contents *seem* right to me, but I
444 can't pretend reading perfectly parser tables... Nonetheless, all
445 the other tests pass correctly, the table look OK, even though the
446 presence of `$axiom' is to be noted: AFAICS it is useless (but
447 harmless).

451 * src/reader.c (readgram): Don't add the rule 0 if there were no
452 rules read. In other words, add it _after_ having performed
453 grammar sanity checks.
454 Fixes the `tests/regression.at (Invalid input: 1)' Failure.

470 Fix the `GAWK Grammar' failure.
471
472 * src/LR0.c (final_state): Initialize to -1 so that we do compute
473 the reductions of the first state which was mistakenly confused
474 with the final state because precisely final_state was initialized
475 to 0.
476 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
477 now noticed by Bison.
478 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
479 have a reduction on $default.

AD		 5232001-12-27 Paul Eggert <eggert@twinsun.com>
524
525 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
526 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
527 Sparc, as they were causing more porting problems than the
528 (minor) performance improvement was worth.
529

536 Use -1 as separator, not 0.
537 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
538 Rely on -1 as separator in yyrhs, instead of 0.
539 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
540 twice `Now at end of input', therefore there are two lines less to
541 expect.

551 * src/LR0.c (new_state): Recognize the final state by the fact it
552 is reached by eoftoken.
553 (insert_start_shifting_state, insert_eof_shifting_state)
554 (insert_accepting_state, augment_automaton): Remove, since now
555 these states are automatically computed from the initial state.
556 (generate_states): Adjust.
557 * src/print.c: When reporting a rule number to the user, substract
558 1, so that the axiom rule is rule 0, and the first user rule is 1.
559 * src/reduce.c: Likewise.
560 * src/print_graph.c (print_core): For the time being, just as for
561 the report, depend upon --trace-flags to dump the full set of
562 items.
563 * src/reader.c (readgram): Once the grammar read, insert the rule
564 0: `$axiom: START-SYMBOL $'.
565 * tests/set.at: Adjust: rule 0 is now displayed, and since the
566 number of the states has changed (the final state is no longer
567 necessarily the last), catch up.

571 Try to make the use of the eoftoken valid. Given that its value
572 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
573 is used instead of > 0 where appropriate, (ii), depend upon nritems
574 instead of the 0-sentinel.
575
576 * src/gram.h, src/gram.c (nritems): New.
577 Expected to be duplication of nitems, but for the time being...
578 * src/reader.c (packgram): Assert nritems and nitems are equal.
579 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
580 * src/closure.c (print_closure, print_fderives): Likewise.

587 * src/main.c (main): If there are complains after grammar
588 reductions, then output the report anyway if requested, then die.
589 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
590 * src/reader.c (eoftoken): New.
591 (parse_token_decl): If the token being defined has value `0', it
592 is the eoftoken.
593 (packsymbols): No longer hack `tags' to insert `$' by hand.
594 Be sure to preserve the value of the eoftoken.
595 (reader): Make sure eoftoken is defined.
596 Initialize nsyms to 0: now eoftoken is created just like the others.
597 * src/print.c (print_grammar): Don't special case the eof token.
598 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
599 lie anyway, albeit pleasant.
600 * tests/calc.at: Exercise error messages with eoftoken.
601 Change the grammar so that empty input is invalid.
602 Adjust expectations.
603 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

688 * src/reader.c (symbol_list): `guard' and `guard_line' are new
689 members.
690 (symbol_list_new): Adjust.
691 (copy_action): action_line is the first line, not the last.
692 (copy_guard): Just as for actions, store the `action' only, not
693 the switch/case/break flesh.
694 Don't parse the user action that might follow the guard, let...
695 (readgram): do it, i.e., now, there can be an action after a
696 guard.
697 In other words the guard is just explicitly optional.
698 (packgram): Adjust.
699 * src/output.c (guards_output): New.
700 (output_parser): Call it when needed.
701 (output): Also free the guard and attrs obstacks.
702 * src/files.c, src/files.h (obstack_save): Remove.
703 (output_files): Remove.
704 As a result, if one needs the former `.act' file, using an
705 appropriate skeleton which requires actions and guards is now
706 required.
707 * src/main.c (main): Adjust.
708 * tests/semantic.at: New.
709 * tests/regression.at: Use `input.y' as input file name.

739 integer when referring to a state.
740 As much as possible, depend upon nlookaheads, instead of the
741 `lookaheadsp' member of the following state (since lookaheads of
742 successive states are successive, the difference between state n + 1
743 and n served as the number of lookaheads for state n).

892
893 Make `make distcheck' work.
894

896 system.h which uses libgettext.h.

899
900 * src/nullable.c (set_nullable): Useless rules must be skipped,
901 otherwise, since we range over their symbols, we might look at a
902 nonterminal which no longer ``exists'', i.e., it is not counted in
903 `nvars', hence we overflow our arrays.

911 (compute_header_macro): Global.
912 (defines_obstack_save): Remove.
913 * src/reader.c (parse_union_decl): No longer output to

915 anyway.

941 Still making progress in separating Bison into (i) input, (ii)
942 process, (iii) output: now we can directly output the parser file
943 without using table_obstack at all.

953 Attach actions to rules, instead of pre-outputting them to
954 actions_obstack.

958 (copy_action): Save the actions within the rule.
959 (packgram): Save them in rule_table.

982 just decode them, and keep them as char (before, eol was output as
983 the 2 char string `\n' etc.).

991 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
992 All uses of `fprintf' and `stderr' changed.

998 The computation of nullable is broken: it doesn't handle empty
999 RHS's properly.
1000
1001 * tests/torture.at (GNU AWK Grammar): New.
1002 * tests/sets.at (Nullable): New.
1003 * src/nullable.c (set_nullable): Instead of blindly looping over
1004 `ritems', loop over the rules, and then over their rhs's.
1005
1006 Work around Autotest bugs.
1007
1008 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1009 frame, because Autotest understand lines starting with a `+' as
1010 traces from the shell. Then, they are not processed properly.
1011 Admittedly an Autotest bug, but we don't have time to wait for
1012 Autotest to catch up.
1013 * tests/regression.at (Broken Closure): Adjust to the new table
1014 frames.

1024
1025 * src/print.c (print_actions): Output the handling of `$' as the
1026 traces do: shifting the token EOF. Before EOF was treated as a
1027 nonterminal.
1028 * tests/regression.at: Adjust some tests.
1029 * src/print_graph.c (print_core): Complete the set of items via
1030 closure. The next-to-final and final states are still unsatisfying,
1031 but that's to be addressed elsewhere.
1032 No longer output the rule numbers, but do output the state number.
1033 A single loop for the shifts + gotos is enough, but picked a
1034 distinct color for each.
1035 (print_graph): Initialize and finalize closure.

AD		 10912001-12-10 Akim Demaille <akim@epita.fr>
1092
1093 Now that states have a complete set of members, the linked list of

1097 * src/LR0.c (first_state, last_state): Remove.
1098 Adjust the callers.
1099 (augment_automaton): Don't look for the shifts that must be added
1100 a shift on EOF: it is those of the state we looked for! But now,
1101 since shifts are attached, it is no longer needed to looking
1102 merely by its id: its number.

1150 Better locality of the variables.
1151 When looking if the start_symbol is shifted from the initial
1152 state, using `while (... symbol != start_symbol ...)' sounds
1153 better than `while (... symbol < start_symbol ...)': If fail
