AD		 362002-02-05 Akim Demaille <akim@epita.fr>
37
38 * data/bison.c++: Adjust to the M4 back end.

40
be2a1a68
AD		 412002-02-05 Akim Demaille <akim@epita.fr>
42
43 Give a try to M4 as a back end.
44
45 * lib/readpipe.c: New, from wdiff.
46 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
47 BISON_HAIRY.
48 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
49 specific values. Now it is m4 that performs the lookup.
50 * src/parse-skel.y: Remove.
51 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
52 * src/output.c (actions_output, guards_output)
53 (token_definitions_output): No longer keeps track of the output
54 line number, hence remove the second argument.
55 (guards_output): Check against the guard member of a rule, not the
56 action member.
57 Adjust callers.
58 (output_skeleton): Don't look for the skeleton location, let m4 do
59 that.
60 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
61 file will be used.
62 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
63 (prepare): Given that for the time being changesyntax is not
64 usable in M4, rename the muscles using `-' to `_'.
65 Define `defines_flag', `output_parser_name' and `output_header_name'.
66 * src/output.h (actions_output, guards_output)
67 (token_definitions_output): Adjust prototypes.
68 * src/scan-skel.l: Instead of scanning the skeletons, it now
69 processes the output of m4: `__oline__' and `#output'.
70 * data/bison.simple: Adjust to be used by M4(sugar).
71 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
72 to date.
73 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
74 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
75 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
76 shamelessly stolen from CVS Autoconf.
77
beda758b
AD		 782002-02-05 Akim Demaille <akim@epita.fr>
79
80 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
81 * configure.in: Check for the declarations of free and malloc.
82 * src/muscle_tab.c: Adjust.
83
5ece6d43
AD		 842002-02-05 Akim Demaille <akim@epita.fr>
85
86 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
87 which have no values.
88
5bb18f9a
AD		 892002-02-05 Akim Demaille <akim@epita.fr>
90
91 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
92 * data/: here.
93
894dd62e
PE		 942002-01-29 Paul Eggert <eggert@twinsun.com>
95
96 * src/bison.simple (YYSIZE_T): Do not define merely because
97 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
98 On some platforms, <alloca.h> does not declare YYSTD (size_t).
99
82841af7
AD		 1002002-01-27 Akim Demaille <akim@epita.fr>
101
102 Fix `%nonassoc and eof'.
103
104 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
105 which were not properly copied! Replace
106 memcpy (res->errs, src->errs, src->nerrs);
107 with
108 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
109 !!!
110 * tests/regression.at (%nonassoc and eof): Adjust to newest
111 Autotest: `.' is not in the PATH.
112
318b76e9
AD		 1132002-01-27 Akim Demaille <akim@epita.fr>
114
115 * tests/sets.at (AT_EXTRACT_SETS): New.
116 (Nullable): Use it.
117 (Firsts): New.
118
30d2f3d5
AD		 1192002-01-26 Akim Demaille <akim@epita.fr>
120
121 * tests/actions.at, tests/calc.at, tests/headers.at,
122 * tests/torture.at: Adjust to the newest Autotest which no longer
123 forces `.' in the PATH.
124
30f8c395
AD		 1252002-01-25 Akim Demaille <akim@epita.fr>
126
127 * tests/regression.at (%nonassoc and eof): New.
128 Suggested by Robert Anisko.

AD		 1302002-01-24 Akim Demaille <akim@epita.fr>
131
132 Bison dumps core when trying to complain about broken input files.
133 Reported by Cris van Pelt.
134
135 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
136 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
137 into...
138 (Invalid inputs): Strengthen: exercise parse_percent_token.
139
2b548aa6
RA		 1402002-01-24 Robert Anisko <robert.anisko@epita.fr>
141
142 * src/Makefile.am: Add bison.c++.
143 * src/bison.c++: New skeleton.
144
bb0146c2
AD		 1452002-01-21 Paolo Bonzini <bonzini@gnu.org>
146
147 * po/it.po: New.
148
bec30531
AD		 1492002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
150
151 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
152
fc6edc45
MA		 1532002-01-20 Marc Autret <marc@gnu.org>
154
155 * src/files.c (compute_output_file_names): Fix
156
5e5d5415
MA		 1572002-01-20 Marc Autret <marc@gnu.org>
158
159 * tests/output.at: New test.
160 * src/files.c (compute_base_names): Don't map extensions when
161 the YACC flag is set, use defaults.
162 Reported by Evgeny Stambulchik.
163
44ea3fbd
MA		 1642002-01-20 Marc Autret <marc@gnu.org>
165
bb0146c2 166 * src/system.h: Need to define __attribute__ away for non-GCC
44ea3fbd
MA		 167 compilers as well (i.e. the vendor C compiler).
168 Suggested by Albert Chin-A-Young.
169
338963d1
TVH		 1702002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
171
172 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
173 canonical definition.
174 * src/system.h: Use the canonical definition for PARAMS (avoids
175 a conflict with the macro from lib/hash.h).
176
c57b2479
AD		 1772002-01-11 Akim Demaille <akim@epita.fr>
178
179 * configure.in: Use AC_FUNC_STRNLEN.
d9e9746c 180 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
c57b2479 181
b85810ae
AD		 1822002-01-09 Akim Demaille <akim@epita.fr>
183
184 * src/files.c, src/files.h (output_infix): New.
185 (tab_extension): Remove.
186 (compute_base_names): Compute the former, drop the latter.
187 * src/output.c (prepare): Insert the muscles `output-infix', and
188 `output-suffix'.
189 * src/parse-skel.y (string, string.1): New.
190 (section.header): Use it.
191 (section.yacc): Remove.
192 (prefix): Remove too.
193 * src/scan-skel.l: Adjust.
194 * src/bison.simple, src/bison.hairy: Adjust.
195
cae60122
AD		 1962002-01-09 Akim Demaille <akim@epita.fr>
197
198 * configure.in (WERROR_CFLAGS): Compute it.
199 * src/Makefile.am (CFLAGS): Pass it.
200 * tests/atlocal.in (CFLAGS): Idem.
201 * src/files.c: Fix a few warnings.
202 (get_extension_index): Remove, unused.
203
ae404801
AD		 2042002-01-08 Akim Demaille <akim@epita.fr>
205
206 * src/getargs.c (AS_FILE_NAME): New.
207 (getargs): Use it to convert DOSish file names.
208 * src/files.c (base_name): Rename as full_base_name to avoid
209 clashes with `base_name ()'.
210 (filename_split): New.
211 (compute_base_names): N-th rewrite, using filename_split.
212
22312b71
AD		 2132002-01-08 Akim Demaille <akim@epita.fr>
214
215 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
216 New, stolen from the Fileutils 4.1.
217 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
218 * configure.in: Check for the presence of memrchr, and of its
219 prototype.
220
a67cef01
TVH		 2212002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
222
223 * lib/hash.h (__P): Added definition for this macro.
224 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
225 BUILT_SOURCES, to ensure they are generated first.
226 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
227 %error-verbose to allow bootstrapping with bison 1.30x.
228
2b25d624
AD		 2292002-01-06 Akim Demaille <akim@epita.fr>
230
231 * src/reader.c (parse_braces): Don't fetch the next char, the
232 convention is to fetch on entry.
233 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
234 'switch' without a following semicolon.
235 * tests/regression.at (braces parsing): New.
236
3460813b
AD		 2372002-01-06 Akim Demaille <akim@epita.fr>
238
239 Bison is dead wrong in its RR conflict reports.
240
241 * tests/torture.at (GNU Cim Grammar): New.
242 * src/conflicts.c (count_rr_conflicts): Fix.
243
73784c64
AD		 2442002-01-06 Akim Demaille <akim@epita.fr>
245
246 Creating package.m4 from configure.ac causes too many problems.
247
248 * tests/Makefile.am (package.m4): Create it by hand,
249 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
250
25d81090
AD		 2512002-01-06 Akim Demaille <akim@epita.fr>
252
253 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
254 skeleton.h.
255
a9b8959e
PE		 2562002-01-04 Paul Eggert <eggert@twinsun.com>
257
258 * doc/bison.texinfo (Debugging):
259 Remove YYSTDERR; it's no longer defined or used.
260 Also, s/cstdio.h/cstdio/.
261
25d81090
AD		 2622002-01-03 Akim Demaille <akim@epita.fr>
263
264 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
265
1109455c
AD		 2662002-01-03 Akim Demaille <akim@epita.fr>
267
268 * src/parse-skel.y (process_skeleton): Don't bind the parser's
269 tracing code to --trace, wait for a better --trace option, with
270 args.
271
7ea5e977
AD		 2722002-01-03 Akim Demaille <akim@epita.fr>
273
274 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
275 The ISO C++ standard is extremely clear about it: stderr is
276 considered a macro, not a regular symbol (see table 94 `Header
277 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
278 Therefore std:: does not apply to it. It still does with fprintf.
279 Also, s/cstdio.h/cstdio/.
280
fab5b110
AD		 2812002-01-03 Akim Demaille <akim@epita.fr>
282
283 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
284 for non system headers.
285
aed7fd9b
AD		 2862002-01-02 Akim Demaille <akim@epita.fr>
287
288 Equip the skeleton chain with location tracking, runtime trace,
289 pure parser and scanner.
290
291 * src/parse-skel.y: Request a pure parser, locations, and prefix
292 renaming.
293 (%union): Having several members with the same type does not help
294 type mismatches, simplify.
295 (YYPRINT, yyprint): New.
296 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
297 (skel_error): this.
298 Handle locations.
299 * src/scan-skel.l: Adjust to these changes.
300 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
301 (LOCATION_PRINT, skel_control_t): New.
302
24fad99e
AD		 3032001-12-30 Akim Demaille <akim@epita.fr>
304
305 * src/parse-skel.y: Get rid of the shift/reduce conflict:
306 replace `gb' with BLANKS.
307 * src/scan-skel.l: Adjust.
308
a4b36db4
AD		 3092001-12-30 Akim Demaille <akim@epita.fr>
310
311 * src/system.h: We don't need nor want bcopy.
312 Throw away MS-DOS crap: we don't need getpid.
313 * configure.in: We don't need strndup. It was even causing
314 problems: because Flex includes the headers *before* us,
315 _GNU_SOURCE is not defined by config.h, and therefore strndup was
316 not visible.
317 * lib/xstrndup.c: New.
318 * src/scan-skel.l: Use it.
319 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
320 * src/parse-skel.y: Use %directives instead of #defines.
321
1239777d
AD		 3222001-12-30 Akim Demaille <akim@epita.fr>
323
324 * src/skeleton.h: New.
325 * src/output.c (output_parser, output_master_parser): Remove, dead
326 code.
327 * src/output.h (get_lines_number, actions_output, guards_output)
328 (token_definitions_output): Prototype them.
329 * src/parse-skel.y: Add the license notice.
330 Include output.h and skeleton.h.
331 (process_skeleton): Returns void, and takes a single parameter.
332 * src/scan-skel.l: Add the license notice.
333 Include skeleton.h.
334 Don't use %option yylineno: it seems that then Flex imagines
335 REJECT has been used, and therefore it won't reallocate its
336 buffers (which makes no other sense to me than a bug). It results
337 in warnings for `unused: yy_flex_realloc'.
338
9b3add5b
RA		 3392001-12-30 Robert Anisko <robert.anisko@epita.fr>
340
341 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
342 (MUSCLE_INSERT_PREFIX): ...to there.
343 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
344 (MUSCLE_INSERT_PREFIX): Move from here...
345
346 * src/bison.hairy: Add a section directive. Put braces around muscle
347 names. This parser skeleton is still broken, but Bison should not
348 choke on a bad muscle 'syntax'.
349 * src/bison.simple: Add a section directive. Put braces around muscle
350 names.
351
352 * src/files.h (strsuffix, stringappend): Add declarations.
353 (tab_extension): Add declaration.
354 (short_base_name): Add declaration.
355
356 * src/files.c (strsuffix, stringappend): No longer static. These
357 functions are used in the skeleton parser.
358 (tab_extension): New.
359 (compute_base_names): Use the computations done in this function
fab5b110 360 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA		 361 names.
362 (short_base_name): No longer static.
363
364 * src/output.c (output_skeleton): New.
365 (output): Disable call to output_master_parser, and give a try to
366 a new skeleton handling system.
367 (guards_output, actions_output): No longer static.
368 (token_definitions_output, get_lines_number): No longer static.
369
370 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
371
fab5b110 372 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA		 373 parse-skel.y.
374
375 * src/parse-skel.y: New file.
376 * src/scan-skel.l: New file.
377
b5b61c61
AD		 3782001-12-29 Akim Demaille <akim@epita.fr>
379
380 %name-prefix is broken.
381
382 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
383 Adjust all dependencies.
384 * tests/headers.at (export YYLTYPE): Strengthen this test: use
385 %name-prefix.
386
387 Renaming yylval but not yylloc is not consistent. Now we do.
388
389 * src/bison.simple: Prefix yylloc if used.
390 * doc/bison.texinfo (Decl Summary): Document that.
391
8c9a50be
AD		 3922001-12-29 Akim Demaille <akim@epita.fr>
393
394 * doc/bison.texinfo: Promote `%long-directive' over
395 `%long_directive'.
396 Remove all references to fixed-output-files, yacc is enough.
397
d99361e6
AD		 3982001-12-29 Akim Demaille <akim@epita.fr>
399
400 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
401 user prologue. These are defaults.
402 * tests/actions.at (Mid-rule actions): Make sure the user can
403 define YYDEBUG and YYERROR_VERBOSE.
404
b9cecb91
AD		 4052001-12-29 Akim Demaille <akim@epita.fr>
406
407 * src/output.c (header_output): Don't forget to export YYLTYPE and
408 yylloc.
409 * tests/headers.at (export YYLTYPE): New, make sure it does.
410 * tests/regression.at (%union and --defines, Invalid CPP headers):
411 Move to...
412 * tests/headers.at: here.
413
aea13e97
AD		 4142001-12-29 Akim Demaille <akim@epita.fr>
415
416 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
417
931394cb
AD		 4182001-12-29 Akim Demaille <akim@epita.fr>
419
420 * tests/actions.at (Mid-rule actions): Output on a single line
421 instead of several.
422
704a47c4
AD		 4232001-12-29 Akim Demaille <akim@epita.fr>
424
425 * doc/bison.texinfo: Formatting changes.
426
091e20bb
AD		 4272001-12-29 Akim Demaille <akim@epita.fr>
428
429 Don't store the token defs in a muscle, just be ready to output it
430 on command. Now possible via `symbols'. Fixes a memory leak.
431
432 * src/output.c (token_definitions_output): New.
433 (output_parser, header_output): Use it.
434 * src/reader.c (symbols_save): Remove.
435
cce71710
AD		 4362001-12-29 Akim Demaille <akim@epita.fr>
437
438 * src/bison.simple: Do not provide a default for YYSTYPE and
439 YYLTYPE before the user's prologue. Otherwise it's hardly... a
440 default.
441
82c035a8
AD		 4422001-12-29 Akim Demaille <akim@epita.fr>
443
444 Mid-rule actions are simply... ignored!
445
446 * src/reader.c (readgram): Be sure to attach mid-rule actions to

533 the other tests pass correctly, the table look OK, even though the

613 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
614 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
615 Sparc, as they were causing more porting problems than the
616 (minor) performance improvement was worth.

625 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
626 Rely on -1 as separator in yyrhs, instead of 0.

628 twice `Now at end of input', therefore there are two lines less to

640 is reached by eoftoken.
641 (insert_start_shifting_state, insert_eof_shifting_state)
642 (insert_accepting_state, augment_automaton): Remove, since now
643 these states are automatically computed from the initial state.
644 (generate_states): Adjust.
645 * src/print.c: When reporting a rule number to the user, substract
646 1, so that the axiom rule is rule 0, and the first user rule is 1.
647 * src/reduce.c: Likewise.
648 * src/print_graph.c (print_core): For the time being, just as for
649 the report, depend upon --trace-flags to dump the full set of
650 items.
651 * src/reader.c (readgram): Once the grammar read, insert the rule
652 0: `$axiom: START-SYMBOL $'.
653 * tests/set.at: Adjust: rule 0 is now displayed, and since the
654 number of the states has changed (the final state is no longer
655 necessarily the last), catch up.

659 Try to make the use of the eoftoken valid. Given that its value
660 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
661 is used instead of > 0 where appropriate, (ii), depend upon nritems
662 instead of the 0-sentinel.
663
664 * src/gram.h, src/gram.c (nritems): New.
665 Expected to be duplication of nitems, but for the time being...
666 * src/reader.c (packgram): Assert nritems and nitems are equal.

676 reductions, then output the report anyway if requested, then die.
677 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
678 * src/reader.c (eoftoken): New.
679 (parse_token_decl): If the token being defined has value `0', it
680 is the eoftoken.
681 (packsymbols): No longer hack `tags' to insert `$' by hand.
682 Be sure to preserve the value of the eoftoken.
683 (reader): Make sure eoftoken is defined.
684 Initialize nsyms to 0: now eoftoken is created just like the others.
685 * src/print.c (print_grammar): Don't special case the eof token.
686 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
687 lie anyway, albeit pleasant.
688 * tests/calc.at: Exercise error messages with eoftoken.
689 Change the grammar so that empty input is invalid.
690 Adjust expectations.
691 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

776 * src/reader.c (symbol_list): `guard' and `guard_line' are new
777 members.
778 (symbol_list_new): Adjust.
779 (copy_action): action_line is the first line, not the last.
780 (copy_guard): Just as for actions, store the `action' only, not
781 the switch/case/break flesh.
782 Don't parse the user action that might follow the guard, let...
783 (readgram): do it, i.e., now, there can be an action after a

789 (output): Also free the guard and attrs obstacks.

792 As a result, if one needs the former `.act' file, using an
793 appropriate skeleton which requires actions and guards is now
794 required.

828 As much as possible, depend upon nlookaheads, instead of the
829 `lookaheadsp' member of the following state (since lookaheads of
830 successive states are successive, the difference between state n + 1

988 * src/nullable.c (set_nullable): Useless rules must be skipped,
989 otherwise, since we range over their symbols, we might look at a
990 nonterminal which no longer ``exists'', i.e., it is not counted in

1041 Attach actions to rules, instead of pre-outputting them to

1086 The computation of nullable is broken: it doesn't handle empty
1087 RHS's properly.
1088
1089 * tests/torture.at (GNU AWK Grammar): New.
1090 * tests/sets.at (Nullable): New.
1091 * src/nullable.c (set_nullable): Instead of blindly looping over
1092 `ritems', loop over the rules, and then over their rhs's.
1093
1094 Work around Autotest bugs.
1095
1096 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1097 frame, because Autotest understand lines starting with a `+' as
1098 traces from the shell. Then, they are not processed properly.
1099 Admittedly an Autotest bug, but we don't have time to wait for
1100 Autotest to catch up.
1101 * tests/regression.at (Broken Closure): Adjust to the new table
1102 frames.

1113 * src/print.c (print_actions): Output the handling of `$' as the
1114 traces do: shifting the token EOF. Before EOF was treated as a
1115 nonterminal.
1116 * tests/regression.at: Adjust some tests.
1117 * src/print_graph.c (print_core): Complete the set of items via
1118 closure. The next-to-final and final states are still unsatisfying,
1119 but that's to be addressed elsewhere.
1120 No longer output the rule numbers, but do output the state number.
1121 A single loop for the shifts + gotos is enough, but picked a
1122 distinct color for each.
1123 (print_graph): Initialize and finalize closure.

1181 Now that states have a complete set of members, the linked list of

1187 (augment_automaton): Don't look for the shifts that must be added

1239 When looking if the start_symbol is shifted from the initial

1316 One structure for states is enough, even though theoretically
1317 there are LR(0) states and LALR(1) states.
1318
1319 * src/lalr.h (state_t): Remove.
1320 (state_table): Be state_t **, not state_t *.
1321 * src/state.h (core, CORE_ALLOC): Rename as...
1322 (state_t, STATE_ALLOC): this.
1323 Add the LALR(1) members: shifts, reductions, errs.
1324 * src/LR0.c (state_table): Rename as...
1325 (state_hash): this, to avoid name clashes with the global
1326 `state_table'.
1327 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
