7 * data/bison.c++: Adjust the parser code. Fix some muscles that were
8 not expanded by m4.

AD		 102002-02-05 Akim Demaille <akim@epita.fr>
11
12 * data/bison.c++: Adjust to the M4 back end.
13 More is certainly needed.

16
17 Give a try to M4 as a back end.
18
19 * lib/readpipe.c: New, from wdiff.
20 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
21 BISON_HAIRY.
22 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
23 specific values. Now it is m4 that performs the lookup.
24 * src/parse-skel.y: Remove.
25 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
26 * src/output.c (actions_output, guards_output)
27 (token_definitions_output): No longer keeps track of the output
28 line number, hence remove the second argument.
29 (guards_output): Check against the guard member of a rule, not the
30 action member.
31 Adjust callers.
32 (output_skeleton): Don't look for the skeleton location, let m4 do
33 that.
34 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
35 file will be used.
36 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
37 (prepare): Given that for the time being changesyntax is not
38 usable in M4, rename the muscles using `-' to `_'.
39 Define `defines_flag', `output_parser_name' and `output_header_name'.
40 * src/output.h (actions_output, guards_output)
41 (token_definitions_output): Adjust prototypes.
42 * src/scan-skel.l: Instead of scanning the skeletons, it now
43 processes the output of m4: `__oline__' and `#output'.
44 * data/bison.simple: Adjust to be used by M4(sugar).
45 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
46 to date.
47 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
48 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
49 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
50 shamelessly stolen from CVS Autoconf.
51

AD		 522002-02-05 Akim Demaille <akim@epita.fr>
53
54 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
55 * configure.in: Check for the declarations of free and malloc.
56 * src/muscle_tab.c: Adjust.
57
5ece6d43
AD		 582002-02-05 Akim Demaille <akim@epita.fr>
59
60 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
61 which have no values.
62
5bb18f9a
AD		 632002-02-05 Akim Demaille <akim@epita.fr>
64
65 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
66 * data/: here.
67
894dd62e
PE		 682002-01-29 Paul Eggert <eggert@twinsun.com>
69
70 * src/bison.simple (YYSIZE_T): Do not define merely because
71 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
72 On some platforms, <alloca.h> does not declare YYSTD (size_t).
73
82841af7
AD		 742002-01-27 Akim Demaille <akim@epita.fr>
75
76 Fix `%nonassoc and eof'.
77
78 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
79 which were not properly copied! Replace
80 memcpy (res->errs, src->errs, src->nerrs);
81 with
82 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
83 !!!
84 * tests/regression.at (%nonassoc and eof): Adjust to newest
85 Autotest: `.' is not in the PATH.
86
318b76e9
AD		 872002-01-27 Akim Demaille <akim@epita.fr>
88
89 * tests/sets.at (AT_EXTRACT_SETS): New.
90 (Nullable): Use it.
91 (Firsts): New.
92
30d2f3d5
AD		 932002-01-26 Akim Demaille <akim@epita.fr>
94
95 * tests/actions.at, tests/calc.at, tests/headers.at,
96 * tests/torture.at: Adjust to the newest Autotest which no longer
97 forces `.' in the PATH.
98
30f8c395
AD		 992002-01-25 Akim Demaille <akim@epita.fr>
100
101 * tests/regression.at (%nonassoc and eof): New.
102 Suggested by Robert Anisko.

AD		 1042002-01-24 Akim Demaille <akim@epita.fr>
105
106 Bison dumps core when trying to complain about broken input files.
107 Reported by Cris van Pelt.
108
109 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
110 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
111 into...
112 (Invalid inputs): Strengthen: exercise parse_percent_token.
113
2b548aa6
RA		 1142002-01-24 Robert Anisko <robert.anisko@epita.fr>
115
116 * src/Makefile.am: Add bison.c++.
117 * src/bison.c++: New skeleton.
118
bb0146c2
AD		 1192002-01-21 Paolo Bonzini <bonzini@gnu.org>
120
121 * po/it.po: New.

bec30531
AD		 1232002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
124
125 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
126
fc6edc45
MA		 1272002-01-20 Marc Autret <marc@gnu.org>
128
129 * src/files.c (compute_output_file_names): Fix
130
5e5d5415
MA		 1312002-01-20 Marc Autret <marc@gnu.org>
132
133 * tests/output.at: New test.
134 * src/files.c (compute_base_names): Don't map extensions when
135 the YACC flag is set, use defaults.
136 Reported by Evgeny Stambulchik.
137
44ea3fbd
MA		 1382002-01-20 Marc Autret <marc@gnu.org>
139
bb0146c2 140 * src/system.h: Need to define __attribute__ away for non-GCC
44ea3fbd
MA		 141 compilers as well (i.e. the vendor C compiler).
142 Suggested by Albert Chin-A-Young.
143
338963d1
TVH		 1442002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
145
146 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
147 canonical definition.
148 * src/system.h: Use the canonical definition for PARAMS (avoids
149 a conflict with the macro from lib/hash.h).
150
c57b2479
AD		 1512002-01-11 Akim Demaille <akim@epita.fr>
152
153 * configure.in: Use AC_FUNC_STRNLEN.
d9e9746c 154 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
c57b2479 155
b85810ae
AD		 1562002-01-09 Akim Demaille <akim@epita.fr>
157
158 * src/files.c, src/files.h (output_infix): New.
159 (tab_extension): Remove.
160 (compute_base_names): Compute the former, drop the latter.
161 * src/output.c (prepare): Insert the muscles `output-infix', and
162 `output-suffix'.
163 * src/parse-skel.y (string, string.1): New.
164 (section.header): Use it.
165 (section.yacc): Remove.
166 (prefix): Remove too.
167 * src/scan-skel.l: Adjust.
168 * src/bison.simple, src/bison.hairy: Adjust.
169
cae60122
AD		 1702002-01-09 Akim Demaille <akim@epita.fr>
171
172 * configure.in (WERROR_CFLAGS): Compute it.
173 * src/Makefile.am (CFLAGS): Pass it.
174 * tests/atlocal.in (CFLAGS): Idem.
175 * src/files.c: Fix a few warnings.
176 (get_extension_index): Remove, unused.
177
ae404801
AD		 1782002-01-08 Akim Demaille <akim@epita.fr>
179
180 * src/getargs.c (AS_FILE_NAME): New.
181 (getargs): Use it to convert DOSish file names.
182 * src/files.c (base_name): Rename as full_base_name to avoid
183 clashes with `base_name ()'.
184 (filename_split): New.
185 (compute_base_names): N-th rewrite, using filename_split.
186
22312b71
AD		 1872002-01-08 Akim Demaille <akim@epita.fr>
188
189 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
190 New, stolen from the Fileutils 4.1.
191 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
192 * configure.in: Check for the presence of memrchr, and of its
193 prototype.
194
a67cef01
TVH		 1952002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
196
197 * lib/hash.h (__P): Added definition for this macro.
198 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
199 BUILT_SOURCES, to ensure they are generated first.
200 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
201 %error-verbose to allow bootstrapping with bison 1.30x.
202
2b25d624
AD		 2032002-01-06 Akim Demaille <akim@epita.fr>
204
205 * src/reader.c (parse_braces): Don't fetch the next char, the
206 convention is to fetch on entry.
207 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
208 'switch' without a following semicolon.
209 * tests/regression.at (braces parsing): New.
210
3460813b
AD		 2112002-01-06 Akim Demaille <akim@epita.fr>
212
213 Bison is dead wrong in its RR conflict reports.
214
215 * tests/torture.at (GNU Cim Grammar): New.
216 * src/conflicts.c (count_rr_conflicts): Fix.
217
73784c64
AD		 2182002-01-06 Akim Demaille <akim@epita.fr>
219
220 Creating package.m4 from configure.ac causes too many problems.
221
222 * tests/Makefile.am (package.m4): Create it by hand,
223 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
224
25d81090
AD		 2252002-01-06 Akim Demaille <akim@epita.fr>
226
227 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
228 skeleton.h.
229
a9b8959e
PE		 2302002-01-04 Paul Eggert <eggert@twinsun.com>
231
232 * doc/bison.texinfo (Debugging):
233 Remove YYSTDERR; it's no longer defined or used.
234 Also, s/cstdio.h/cstdio/.
235
25d81090
AD		 2362002-01-03 Akim Demaille <akim@epita.fr>
237
238 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
239
1109455c
AD		 2402002-01-03 Akim Demaille <akim@epita.fr>
241
242 * src/parse-skel.y (process_skeleton): Don't bind the parser's
243 tracing code to --trace, wait for a better --trace option, with
244 args.
245
7ea5e977
AD		 2462002-01-03 Akim Demaille <akim@epita.fr>
247
248 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
249 The ISO C++ standard is extremely clear about it: stderr is
250 considered a macro, not a regular symbol (see table 94 `Header
251 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
252 Therefore std:: does not apply to it. It still does with fprintf.
253 Also, s/cstdio.h/cstdio/.
254
fab5b110
AD		 2552002-01-03 Akim Demaille <akim@epita.fr>
256
257 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
258 for non system headers.
259
aed7fd9b
AD		 2602002-01-02 Akim Demaille <akim@epita.fr>
261
262 Equip the skeleton chain with location tracking, runtime trace,
263 pure parser and scanner.
264
265 * src/parse-skel.y: Request a pure parser, locations, and prefix
266 renaming.
267 (%union): Having several members with the same type does not help
268 type mismatches, simplify.
269 (YYPRINT, yyprint): New.
270 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
271 (skel_error): this.
272 Handle locations.
273 * src/scan-skel.l: Adjust to these changes.
274 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
275 (LOCATION_PRINT, skel_control_t): New.
276
24fad99e
AD		 2772001-12-30 Akim Demaille <akim@epita.fr>
278
279 * src/parse-skel.y: Get rid of the shift/reduce conflict:
280 replace `gb' with BLANKS.
281 * src/scan-skel.l: Adjust.
282
a4b36db4
AD		 2832001-12-30 Akim Demaille <akim@epita.fr>
284
285 * src/system.h: We don't need nor want bcopy.
286 Throw away MS-DOS crap: we don't need getpid.
287 * configure.in: We don't need strndup. It was even causing
288 problems: because Flex includes the headers *before* us,
289 _GNU_SOURCE is not defined by config.h, and therefore strndup was
290 not visible.
291 * lib/xstrndup.c: New.
292 * src/scan-skel.l: Use it.
293 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
294 * src/parse-skel.y: Use %directives instead of #defines.
295
1239777d
AD		 2962001-12-30 Akim Demaille <akim@epita.fr>
297
298 * src/skeleton.h: New.
299 * src/output.c (output_parser, output_master_parser): Remove, dead
300 code.
301 * src/output.h (get_lines_number, actions_output, guards_output)
302 (token_definitions_output): Prototype them.
303 * src/parse-skel.y: Add the license notice.
304 Include output.h and skeleton.h.
305 (process_skeleton): Returns void, and takes a single parameter.
306 * src/scan-skel.l: Add the license notice.
307 Include skeleton.h.
308 Don't use %option yylineno: it seems that then Flex imagines
309 REJECT has been used, and therefore it won't reallocate its
310 buffers (which makes no other sense to me than a bug). It results
311 in warnings for `unused: yy_flex_realloc'.
312
9b3add5b
RA		 3132001-12-30 Robert Anisko <robert.anisko@epita.fr>
314
315 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
316 (MUSCLE_INSERT_PREFIX): ...to there.
317 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
318 (MUSCLE_INSERT_PREFIX): Move from here...
319
320 * src/bison.hairy: Add a section directive. Put braces around muscle
321 names. This parser skeleton is still broken, but Bison should not
322 choke on a bad muscle 'syntax'.
323 * src/bison.simple: Add a section directive. Put braces around muscle
324 names.
325
326 * src/files.h (strsuffix, stringappend): Add declarations.
327 (tab_extension): Add declaration.
328 (short_base_name): Add declaration.
329
330 * src/files.c (strsuffix, stringappend): No longer static. These
331 functions are used in the skeleton parser.
332 (tab_extension): New.
333 (compute_base_names): Use the computations done in this function
fab5b110 334 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA		 335 names.
336 (short_base_name): No longer static.
337
338 * src/output.c (output_skeleton): New.
339 (output): Disable call to output_master_parser, and give a try to
340 a new skeleton handling system.
341 (guards_output, actions_output): No longer static.
342 (token_definitions_output, get_lines_number): No longer static.
343
344 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
345
fab5b110 346 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA		 347 parse-skel.y.
348
349 * src/parse-skel.y: New file.
350 * src/scan-skel.l: New file.
351
b5b61c61
AD		 3522001-12-29 Akim Demaille <akim@epita.fr>
353
354 %name-prefix is broken.
355
356 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
357 Adjust all dependencies.
358 * tests/headers.at (export YYLTYPE): Strengthen this test: use
359 %name-prefix.
360
361 Renaming yylval but not yylloc is not consistent. Now we do.
362
363 * src/bison.simple: Prefix yylloc if used.
364 * doc/bison.texinfo (Decl Summary): Document that.
365
8c9a50be
AD		 3662001-12-29 Akim Demaille <akim@epita.fr>
367
368 * doc/bison.texinfo: Promote `%long-directive' over
369 `%long_directive'.
370 Remove all references to fixed-output-files, yacc is enough.
371
d99361e6
AD		 3722001-12-29 Akim Demaille <akim@epita.fr>
373
374 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
375 user prologue. These are defaults.
376 * tests/actions.at (Mid-rule actions): Make sure the user can
377 define YYDEBUG and YYERROR_VERBOSE.
378
b9cecb91
AD		 3792001-12-29 Akim Demaille <akim@epita.fr>
380
381 * src/output.c (header_output): Don't forget to export YYLTYPE and
382 yylloc.
383 * tests/headers.at (export YYLTYPE): New, make sure it does.
384 * tests/regression.at (%union and --defines, Invalid CPP headers):
385 Move to...
386 * tests/headers.at: here.
387
aea13e97
AD		 3882001-12-29 Akim Demaille <akim@epita.fr>
389
390 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
391
931394cb
AD		 3922001-12-29 Akim Demaille <akim@epita.fr>
393
394 * tests/actions.at (Mid-rule actions): Output on a single line
395 instead of several.
396
704a47c4
AD		 3972001-12-29 Akim Demaille <akim@epita.fr>
398
399 * doc/bison.texinfo: Formatting changes.
400
091e20bb
AD		 4012001-12-29 Akim Demaille <akim@epita.fr>
402
403 Don't store the token defs in a muscle, just be ready to output it
404 on command. Now possible via `symbols'. Fixes a memory leak.
405
406 * src/output.c (token_definitions_output): New.
407 (output_parser, header_output): Use it.
408 * src/reader.c (symbols_save): Remove.
409
cce71710
AD		 4102001-12-29 Akim Demaille <akim@epita.fr>
411
412 * src/bison.simple: Do not provide a default for YYSTYPE and
413 YYLTYPE before the user's prologue. Otherwise it's hardly... a
414 default.
415
82c035a8
AD		 4162001-12-29 Akim Demaille <akim@epita.fr>
417
418 Mid-rule actions are simply... ignored!
419
420 * src/reader.c (readgram): Be sure to attach mid-rule actions to
421 the empty-rule associated to the dummy symbol, not to the host
422 rule.
423 * tests/actions.at (Mid-rule actions): New.
424
8419d367
AD		 4252001-12-29 Akim Demaille <akim@epita.fr>
426
427 Memory leak.
428
429 * src/reader.c (reader): Free grammar.
430
375d5806
AD		 4312001-12-29 Akim Demaille <akim@epita.fr>
432
433 Memory leak.
434
435 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
436 since it allocates it for each state, although only one is needed.
437 (allocate_storage): Do it here.
438
f51cb8ff
AD		 4392001-12-29 Akim Demaille <akim@epita.fr>
440
441 * src/options.h, src/options.c (create_long_option_table): Rename
442 as...
443 (long_option_table_new): this, with a clearer prototype.
444 (percent_table): Remove, unused,
445 * src/getargs.c (getargs): Adjust.
446
29e88316
AD		 4472001-12-29 Akim Demaille <akim@epita.fr>
448
449 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

505 output as expected output. The contents *seem* right to me, but I
506 can't pretend reading perfectly parser tables... Nonetheless, all
507 the other tests pass correctly, the table look OK, even though the
508 presence of `$axiom' is to be noted: AFAICS it is useless (but
509 harmless).

532 Fix the `GAWK Grammar' failure.
533
534 * src/LR0.c (final_state): Initialize to -1 so that we do compute
535 the reductions of the first state which was mistakenly confused
536 with the final state because precisely final_state was initialized
537 to 0.
538 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
539 now noticed by Bison.
540 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does

AD		 5852001-12-27 Paul Eggert <eggert@twinsun.com>
586
587 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
588 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
589 Sparc, as they were causing more porting problems than the
590 (minor) performance improvement was worth.
591

597 0-sentinel. See below.
598 Use -1 as separator, not 0.
599 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
600 Rely on -1 as separator in yyrhs, instead of 0.
601 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
602 twice `Now at end of input', therefore there are two lines less to
603 expect.

612
613 * src/LR0.c (new_state): Recognize the final state by the fact it
614 is reached by eoftoken.
615 (insert_start_shifting_state, insert_eof_shifting_state)
616 (insert_accepting_state, augment_automaton): Remove, since now
617 these states are automatically computed from the initial state.
618 (generate_states): Adjust.
619 * src/print.c: When reporting a rule number to the user, substract
620 1, so that the axiom rule is rule 0, and the first user rule is 1.
621 * src/reduce.c: Likewise.
622 * src/print_graph.c (print_core): For the time being, just as for
623 the report, depend upon --trace-flags to dump the full set of
624 items.
625 * src/reader.c (readgram): Once the grammar read, insert the rule
626 0: `$axiom: START-SYMBOL $'.
627 * tests/set.at: Adjust: rule 0 is now displayed, and since the
628 number of the states has changed (the final state is no longer
629 necessarily the last), catch up.

632
633 Try to make the use of the eoftoken valid. Given that its value
634 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
635 is used instead of > 0 where appropriate, (ii), depend upon nritems
636 instead of the 0-sentinel.
637
638 * src/gram.h, src/gram.c (nritems): New.
639 Expected to be duplication of nitems, but for the time being...
640 * src/reader.c (packgram): Assert nritems and nitems are equal.
641 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
642 * src/closure.c (print_closure, print_fderives): Likewise.

648
649 * src/main.c (main): If there are complains after grammar
650 reductions, then output the report anyway if requested, then die.
651 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
652 * src/reader.c (eoftoken): New.
653 (parse_token_decl): If the token being defined has value `0', it
654 is the eoftoken.
655 (packsymbols): No longer hack `tags' to insert `$' by hand.
656 Be sure to preserve the value of the eoftoken.
657 (reader): Make sure eoftoken is defined.
658 Initialize nsyms to 0: now eoftoken is created just like the others.
659 * src/print.c (print_grammar): Don't special case the eof token.
660 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
661 lie anyway, albeit pleasant.
662 * tests/calc.at: Exercise error messages with eoftoken.
663 Change the grammar so that empty input is invalid.
664 Adjust expectations.
665 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

750 * src/reader.c (symbol_list): `guard' and `guard_line' are new
751 members.
752 (symbol_list_new): Adjust.
753 (copy_action): action_line is the first line, not the last.
754 (copy_guard): Just as for actions, store the `action' only, not
755 the switch/case/break flesh.
756 Don't parse the user action that might follow the guard, let...
757 (readgram): do it, i.e., now, there can be an action after a
758 guard.
759 In other words the guard is just explicitly optional.
760 (packgram): Adjust.
761 * src/output.c (guards_output): New.
762 (output_parser): Call it when needed.
763 (output): Also free the guard and attrs obstacks.
764 * src/files.c, src/files.h (obstack_save): Remove.
765 (output_files): Remove.
766 As a result, if one needs the former `.act' file, using an
767 appropriate skeleton which requires actions and guards is now
768 required.
769 * src/main.c (main): Adjust.
770 * tests/semantic.at: New.

801 integer when referring to a state.
802 As much as possible, depend upon nlookaheads, instead of the
803 `lookaheadsp' member of the following state (since lookaheads of
804 successive states are successive, the difference between state n + 1
805 and n served as the number of lookaheads for state n).

962 * src/nullable.c (set_nullable): Useless rules must be skipped,

964 nonterminal which no longer ``exists'', i.e., it is not counted in

1060 The computation of nullable is broken: it doesn't handle empty
1061 RHS's properly.
1062
1063 * tests/torture.at (GNU AWK Grammar): New.
1064 * tests/sets.at (Nullable): New.
1065 * src/nullable.c (set_nullable): Instead of blindly looping over
1066 `ritems', loop over the rules, and then over their rhs's.
1067
1068 Work around Autotest bugs.
1069
1070 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1071 frame, because Autotest understand lines starting with a `+' as
1072 traces from the shell. Then, they are not processed properly.
1073 Admittedly an Autotest bug, but we don't have time to wait for
1074 Autotest to catch up.

1076 frames.

1086
1087 * src/print.c (print_actions): Output the handling of `$' as the
1088 traces do: shifting the token EOF. Before EOF was treated as a
1089 nonterminal.
1090 * tests/regression.at: Adjust some tests.
1091 * src/print_graph.c (print_core): Complete the set of items via
1092 closure. The next-to-final and final states are still unsatisfying,
1093 but that's to be addressed elsewhere.
1094 No longer output the rule numbers, but do output the state number.
1095 A single loop for the shifts + gotos is enough, but picked a
1096 distinct color for each.
1097 (print_graph): Initialize and finalize closure.

1155 Now that states have a complete set of members, the linked list of

1160 Adjust the callers.
1161 (augment_automaton): Don't look for the shifts that must be added
1162 a shift on EOF: it is those of the state we looked for! But now,

1164 merely by its id: its number.

1212 Better locality of the variables.
1213 When looking if the start_symbol is shifted from the initial
