2
3 * data/bison.c++: Replace some direct m4 expansions by constants. Be
4 more consistent when naming methods and variables. Put preprocessor
5 directives around tables only needed for debugging.

9 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
10 C++ parsers.
11 (yy::b4_name::parse): Use print_.

34 * data/bison.c++: Adjust to the M4 back end.
35 More is certainly needed.

AD		 372002-02-05 Akim Demaille <akim@epita.fr>
38
39 Give a try to M4 as a back end.
40
41 * lib/readpipe.c: New, from wdiff.
42 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
43 BISON_HAIRY.
44 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
45 specific values. Now it is m4 that performs the lookup.
46 * src/parse-skel.y: Remove.
47 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
48 * src/output.c (actions_output, guards_output)
49 (token_definitions_output): No longer keeps track of the output
50 line number, hence remove the second argument.
51 (guards_output): Check against the guard member of a rule, not the
52 action member.
53 Adjust callers.
54 (output_skeleton): Don't look for the skeleton location, let m4 do
55 that.
56 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
57 file will be used.
58 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
59 (prepare): Given that for the time being changesyntax is not
60 usable in M4, rename the muscles using `-' to `_'.
61 Define `defines_flag', `output_parser_name' and `output_header_name'.
62 * src/output.h (actions_output, guards_output)
63 (token_definitions_output): Adjust prototypes.
64 * src/scan-skel.l: Instead of scanning the skeletons, it now
65 processes the output of m4: `__oline__' and `#output'.
66 * data/bison.simple: Adjust to be used by M4(sugar).
67 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
68 to date.
69 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
70 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
71 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
72 shamelessly stolen from CVS Autoconf.
73

AD		 742002-02-05 Akim Demaille <akim@epita.fr>
75
76 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
77 * configure.in: Check for the declarations of free and malloc.
78 * src/muscle_tab.c: Adjust.
79
5ece6d43
AD		 802002-02-05 Akim Demaille <akim@epita.fr>

82 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
83 which have no values.
84
5bb18f9a
AD		 852002-02-05 Akim Demaille <akim@epita.fr>
86
87 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
88 * data/: here.
89
894dd62e
PE		 902002-01-29 Paul Eggert <eggert@twinsun.com>
91
92 * src/bison.simple (YYSIZE_T): Do not define merely because
93 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
94 On some platforms, <alloca.h> does not declare YYSTD (size_t).
95
82841af7
AD		 962002-01-27 Akim Demaille <akim@epita.fr>
97
98 Fix `%nonassoc and eof'.
99
100 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
101 which were not properly copied! Replace
102 memcpy (res->errs, src->errs, src->nerrs);
103 with
104 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
105 !!!
106 * tests/regression.at (%nonassoc and eof): Adjust to newest
107 Autotest: `.' is not in the PATH.
108
318b76e9
AD		 1092002-01-27 Akim Demaille <akim@epita.fr>
110
111 * tests/sets.at (AT_EXTRACT_SETS): New.
112 (Nullable): Use it.
113 (Firsts): New.
114
30d2f3d5
AD		 1152002-01-26 Akim Demaille <akim@epita.fr>
116
117 * tests/actions.at, tests/calc.at, tests/headers.at,
118 * tests/torture.at: Adjust to the newest Autotest which no longer
119 forces `.' in the PATH.
120
30f8c395
AD		 1212002-01-25 Akim Demaille <akim@epita.fr>
122
123 * tests/regression.at (%nonassoc and eof): New.

127
128 Bison dumps core when trying to complain about broken input files.
129 Reported by Cris van Pelt.
130
131 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
132 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
133 into...
134 (Invalid inputs): Strengthen: exercise parse_percent_token.
135
2b548aa6
RA		 1362002-01-24 Robert Anisko <robert.anisko@epita.fr>
137
138 * src/Makefile.am: Add bison.c++.
139 * src/bison.c++: New skeleton.
140
bb0146c2
AD		 1412002-01-21 Paolo Bonzini <bonzini@gnu.org>
142

AD		 1452002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
146
147 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
148
fc6edc45
MA		 1492002-01-20 Marc Autret <marc@gnu.org>
150
151 * src/files.c (compute_output_file_names): Fix
152
5e5d5415
MA		 1532002-01-20 Marc Autret <marc@gnu.org>
154
155 * tests/output.at: New test.
156 * src/files.c (compute_base_names): Don't map extensions when
157 the YACC flag is set, use defaults.
158 Reported by Evgeny Stambulchik.
159
44ea3fbd
MA		 1602002-01-20 Marc Autret <marc@gnu.org>
161
bb0146c2 162 * src/system.h: Need to define __attribute__ away for non-GCC
44ea3fbd
MA		 163 compilers as well (i.e. the vendor C compiler).
164 Suggested by Albert Chin-A-Young.
165
338963d1
TVH		 1662002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
167
168 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
169 canonical definition.
170 * src/system.h: Use the canonical definition for PARAMS (avoids
171 a conflict with the macro from lib/hash.h).
172
c57b2479
AD		 1732002-01-11 Akim Demaille <akim@epita.fr>
174
175 * configure.in: Use AC_FUNC_STRNLEN.
d9e9746c 176 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
c57b2479 177
b85810ae
AD		 1782002-01-09 Akim Demaille <akim@epita.fr>
179
180 * src/files.c, src/files.h (output_infix): New.
181 (tab_extension): Remove.
182 (compute_base_names): Compute the former, drop the latter.
183 * src/output.c (prepare): Insert the muscles `output-infix', and
184 `output-suffix'.
185 * src/parse-skel.y (string, string.1): New.
186 (section.header): Use it.
187 (section.yacc): Remove.
188 (prefix): Remove too.
189 * src/scan-skel.l: Adjust.
190 * src/bison.simple, src/bison.hairy: Adjust.
191
cae60122
AD		 1922002-01-09 Akim Demaille <akim@epita.fr>
193
194 * configure.in (WERROR_CFLAGS): Compute it.
195 * src/Makefile.am (CFLAGS): Pass it.
196 * tests/atlocal.in (CFLAGS): Idem.
197 * src/files.c: Fix a few warnings.
198 (get_extension_index): Remove, unused.
199
ae404801
AD		 2002002-01-08 Akim Demaille <akim@epita.fr>
201
202 * src/getargs.c (AS_FILE_NAME): New.
203 (getargs): Use it to convert DOSish file names.
204 * src/files.c (base_name): Rename as full_base_name to avoid
205 clashes with `base_name ()'.
206 (filename_split): New.
207 (compute_base_names): N-th rewrite, using filename_split.
208
22312b71
AD		 2092002-01-08 Akim Demaille <akim@epita.fr>
210
211 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
212 New, stolen from the Fileutils 4.1.
213 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
214 * configure.in: Check for the presence of memrchr, and of its
215 prototype.
216
a67cef01
TVH		 2172002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
218
219 * lib/hash.h (__P): Added definition for this macro.
220 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
221 BUILT_SOURCES, to ensure they are generated first.
222 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
223 %error-verbose to allow bootstrapping with bison 1.30x.
224
2b25d624
AD		 2252002-01-06 Akim Demaille <akim@epita.fr>
226
227 * src/reader.c (parse_braces): Don't fetch the next char, the
228 convention is to fetch on entry.
229 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
230 'switch' without a following semicolon.
231 * tests/regression.at (braces parsing): New.
232
3460813b
AD		 2332002-01-06 Akim Demaille <akim@epita.fr>
234
235 Bison is dead wrong in its RR conflict reports.
236
237 * tests/torture.at (GNU Cim Grammar): New.
238 * src/conflicts.c (count_rr_conflicts): Fix.
239
73784c64
AD		 2402002-01-06 Akim Demaille <akim@epita.fr>
241
242 Creating package.m4 from configure.ac causes too many problems.
243
244 * tests/Makefile.am (package.m4): Create it by hand,
245 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
246
25d81090
AD		 2472002-01-06 Akim Demaille <akim@epita.fr>
248
249 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
250 skeleton.h.
251
a9b8959e
PE		 2522002-01-04 Paul Eggert <eggert@twinsun.com>
253
254 * doc/bison.texinfo (Debugging):
255 Remove YYSTDERR; it's no longer defined or used.
256 Also, s/cstdio.h/cstdio/.
257
25d81090
AD		 2582002-01-03 Akim Demaille <akim@epita.fr>
259
260 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
261
1109455c
AD		 2622002-01-03 Akim Demaille <akim@epita.fr>
263
264 * src/parse-skel.y (process_skeleton): Don't bind the parser's
265 tracing code to --trace, wait for a better --trace option, with
266 args.
267
7ea5e977
AD		 2682002-01-03 Akim Demaille <akim@epita.fr>
269
270 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
271 The ISO C++ standard is extremely clear about it: stderr is
272 considered a macro, not a regular symbol (see table 94 `Header
273 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
274 Therefore std:: does not apply to it. It still does with fprintf.
275 Also, s/cstdio.h/cstdio/.
276
fab5b110
AD		 2772002-01-03 Akim Demaille <akim@epita.fr>
278
279 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
280 for non system headers.
281
aed7fd9b
AD		 2822002-01-02 Akim Demaille <akim@epita.fr>
283
284 Equip the skeleton chain with location tracking, runtime trace,
285 pure parser and scanner.
286
287 * src/parse-skel.y: Request a pure parser, locations, and prefix
288 renaming.
289 (%union): Having several members with the same type does not help
290 type mismatches, simplify.
291 (YYPRINT, yyprint): New.
292 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
293 (skel_error): this.
294 Handle locations.
295 * src/scan-skel.l: Adjust to these changes.
296 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
297 (LOCATION_PRINT, skel_control_t): New.
298
24fad99e
AD		 2992001-12-30 Akim Demaille <akim@epita.fr>
300
301 * src/parse-skel.y: Get rid of the shift/reduce conflict:
302 replace `gb' with BLANKS.
303 * src/scan-skel.l: Adjust.
304
a4b36db4
AD		 3052001-12-30 Akim Demaille <akim@epita.fr>
306
307 * src/system.h: We don't need nor want bcopy.
308 Throw away MS-DOS crap: we don't need getpid.
309 * configure.in: We don't need strndup. It was even causing
310 problems: because Flex includes the headers *before* us,
311 _GNU_SOURCE is not defined by config.h, and therefore strndup was
312 not visible.
313 * lib/xstrndup.c: New.
314 * src/scan-skel.l: Use it.
315 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
316 * src/parse-skel.y: Use %directives instead of #defines.
317
1239777d
AD		 3182001-12-30 Akim Demaille <akim@epita.fr>
319
320 * src/skeleton.h: New.
321 * src/output.c (output_parser, output_master_parser): Remove, dead
322 code.
323 * src/output.h (get_lines_number, actions_output, guards_output)
324 (token_definitions_output): Prototype them.
325 * src/parse-skel.y: Add the license notice.
326 Include output.h and skeleton.h.
327 (process_skeleton): Returns void, and takes a single parameter.
328 * src/scan-skel.l: Add the license notice.
329 Include skeleton.h.
330 Don't use %option yylineno: it seems that then Flex imagines
331 REJECT has been used, and therefore it won't reallocate its
332 buffers (which makes no other sense to me than a bug). It results
333 in warnings for `unused: yy_flex_realloc'.
334
9b3add5b
RA		 3352001-12-30 Robert Anisko <robert.anisko@epita.fr>
336
337 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
338 (MUSCLE_INSERT_PREFIX): ...to there.
339 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
340 (MUSCLE_INSERT_PREFIX): Move from here...
341
342 * src/bison.hairy: Add a section directive. Put braces around muscle
343 names. This parser skeleton is still broken, but Bison should not
344 choke on a bad muscle 'syntax'.
345 * src/bison.simple: Add a section directive. Put braces around muscle
346 names.
347
348 * src/files.h (strsuffix, stringappend): Add declarations.
349 (tab_extension): Add declaration.
350 (short_base_name): Add declaration.
351
352 * src/files.c (strsuffix, stringappend): No longer static. These
353 functions are used in the skeleton parser.
354 (tab_extension): New.
355 (compute_base_names): Use the computations done in this function
fab5b110 356 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA		 357 names.
358 (short_base_name): No longer static.
359
360 * src/output.c (output_skeleton): New.
361 (output): Disable call to output_master_parser, and give a try to
362 a new skeleton handling system.
363 (guards_output, actions_output): No longer static.
364 (token_definitions_output, get_lines_number): No longer static.
365
366 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
367
fab5b110 368 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA		 369 parse-skel.y.
370
371 * src/parse-skel.y: New file.
372 * src/scan-skel.l: New file.
373
b5b61c61
AD		 3742001-12-29 Akim Demaille <akim@epita.fr>
375
376 %name-prefix is broken.
377
378 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
379 Adjust all dependencies.
380 * tests/headers.at (export YYLTYPE): Strengthen this test: use
381 %name-prefix.
382
383 Renaming yylval but not yylloc is not consistent. Now we do.
384
385 * src/bison.simple: Prefix yylloc if used.
386 * doc/bison.texinfo (Decl Summary): Document that.
387
8c9a50be
AD		 3882001-12-29 Akim Demaille <akim@epita.fr>
389
390 * doc/bison.texinfo: Promote `%long-directive' over
391 `%long_directive'.
392 Remove all references to fixed-output-files, yacc is enough.
393
d99361e6
AD		 3942001-12-29 Akim Demaille <akim@epita.fr>
395
396 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
397 user prologue. These are defaults.
398 * tests/actions.at (Mid-rule actions): Make sure the user can
399 define YYDEBUG and YYERROR_VERBOSE.
400
b9cecb91
AD		 4012001-12-29 Akim Demaille <akim@epita.fr>
402
403 * src/output.c (header_output): Don't forget to export YYLTYPE and
404 yylloc.
405 * tests/headers.at (export YYLTYPE): New, make sure it does.
406 * tests/regression.at (%union and --defines, Invalid CPP headers):
407 Move to...
408 * tests/headers.at: here.
409
aea13e97
AD		 4102001-12-29 Akim Demaille <akim@epita.fr>
411
412 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
413
931394cb
AD		 4142001-12-29 Akim Demaille <akim@epita.fr>
415
416 * tests/actions.at (Mid-rule actions): Output on a single line
417 instead of several.
418
704a47c4
AD		 4192001-12-29 Akim Demaille <akim@epita.fr>
420
421 * doc/bison.texinfo: Formatting changes.
422
091e20bb
AD		 4232001-12-29 Akim Demaille <akim@epita.fr>
424
425 Don't store the token defs in a muscle, just be ready to output it
426 on command. Now possible via `symbols'. Fixes a memory leak.
427
428 * src/output.c (token_definitions_output): New.
429 (output_parser, header_output): Use it.
430 * src/reader.c (symbols_save): Remove.
431
cce71710
AD		 4322001-12-29 Akim Demaille <akim@epita.fr>
433
434 * src/bison.simple: Do not provide a default for YYSTYPE and
435 YYLTYPE before the user's prologue. Otherwise it's hardly... a
436 default.
437
82c035a8
AD		 4382001-12-29 Akim Demaille <akim@epita.fr>
439
440 Mid-rule actions are simply... ignored!
441
442 * src/reader.c (readgram): Be sure to attach mid-rule actions to
443 the empty-rule associated to the dummy symbol, not to the host
444 rule.
445 * tests/actions.at (Mid-rule actions): New.
446
8419d367
AD		 4472001-12-29 Akim Demaille <akim@epita.fr>
448

610 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
611 Sparc, as they were causing more porting problems than the
612 (minor) performance improvement was worth.

622 Rely on -1 as separator in yyrhs, instead of 0.

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

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

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

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

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

781 In other words the guard is just explicitly optional.

783 * src/output.c (guards_output): New.

785 (output): Also free the guard and attrs obstacks.
786 * src/files.c, src/files.h (obstack_save): Remove.

788 As a result, if one needs the former `.act' file, using an
789 appropriate skeleton which requires actions and guards is now
790 required.
791 * src/main.c (main): Adjust.
792 * tests/semantic.at: New.

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

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

1082 The computation of nullable is broken: it doesn't handle empty
1083 RHS's properly.
1084
1085 * tests/torture.at (GNU AWK Grammar): New.
1086 * tests/sets.at (Nullable): New.
1087 * src/nullable.c (set_nullable): Instead of blindly looping over
1088 `ritems', loop over the rules, and then over their rhs's.
1089
1090 Work around Autotest bugs.
1091
1092 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1093 frame, because Autotest understand lines starting with a `+' as
1094 traces from the shell. Then, they are not processed properly.
1095 Admittedly an Autotest bug, but we don't have time to wait for
1096 Autotest to catch up.
1097 * tests/regression.at (Broken Closure): Adjust to the new table
1098 frames.

1108
1109 * src/print.c (print_actions): Output the handling of `$' as the
1110 traces do: shifting the token EOF. Before EOF was treated as a
1111 nonterminal.
1112 * tests/regression.at: Adjust some tests.
1113 * src/print_graph.c (print_core): Complete the set of items via
1114 closure. The next-to-final and final states are still unsatisfying,
1115 but that's to be addressed elsewhere.
1116 No longer output the rule numbers, but do output the state number.
1117 A single loop for the shifts + gotos is enough, but picked a
1118 distinct color for each.
1119 (print_graph): Initialize and finalize closure.

1176
1177 Now that states have a complete set of members, the linked list of

1183 (augment_automaton): Don't look for the shifts that must be added
1184 a shift on EOF: it is those of the state we looked for! But now,

1235 When looking if the start_symbol is shifted from the initial

1312 One structure for states is enough, even though theoretically
1313 there are LR(0) states and LALR(1) states.
1314
1315 * src/lalr.h (state_t): Remove.
1316 (state_table): Be state_t **, not state_t *.
1317 * src/state.h (core, CORE_ALLOC): Rename as...
1318 (state_t, STATE_ALLOC): this.
1319 Add the LALR(1) members: shifts, reductions, errs.
1320 * src/LR0.c (state_table): Rename as...
1321 (state_hash): this, to avoid name clashes with the global
1322 `state_table'.
1323 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1324 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
