10 * src/system.h: Need to define __attribute__ away for non-GCC
11 compilers as well (i.e. the vendor C compiler).
12 Suggested by Albert Chin-A-Young.

15
16 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17 canonical definition.
18 * src/system.h: Use the canonical definition for PARAMS (avoids
19 a conflict with the macro from lib/hash.h).

50 * src/getargs.c (AS_FILE_NAME): New.
51 (getargs): Use it to convert DOSish file names.
52 * src/files.c (base_name): Rename as full_base_name to avoid
53 clashes with `base_name ()'.

60 New, stolen from the Fileutils 4.1.
61 * lib/Makefile.am (libbison_a_SOURCES): Adjust.

652002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
66
67 * lib/hash.h (__P): Added definition for this macro.
68 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
69 BUILT_SOURCES, to ensure they are generated first.
70 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
71 %error-verbose to allow bootstrapping with bison 1.30x.

732002-01-06 Akim Demaille <akim@epita.fr>
74
75 * src/reader.c (parse_braces): Don't fetch the next char, the
76 convention is to fetch on entry.
77 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
78 'switch' without a following semicolon.
79 * tests/regression.at (braces parsing): New.

83 Bison is dead wrong in its RR conflict reports.
84
85 * tests/torture.at (GNU Cim Grammar): New.
86 * src/conflicts.c (count_rr_conflicts): Fix.

89
90 Creating package.m4 from configure.ac causes too many problems.
91
92 * tests/Makefile.am (package.m4): Create it by hand,
93 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
94
25d81090
AD
952002-01-06 Akim Demaille <akim@epita.fr>
96
97 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and

1002002-01-04 Paul Eggert <eggert@twinsun.com>
101
102 * doc/bison.texinfo (Debugging):
103 Remove YYSTDERR; it's no longer defined or used.
104 Also, s/cstdio.h/cstdio/.
105

AD
1062002-01-03 Akim Demaille <akim@epita.fr>

AD
1102002-01-03 Akim Demaille <akim@epita.fr>
111
112 * src/parse-skel.y (process_skeleton): Don't bind the parser's
113 tracing code to --trace, wait for a better --trace option, with
114 args.
115

AD
1162002-01-03 Akim Demaille <akim@epita.fr>
117
118 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
119 The ISO C++ standard is extremely clear about it: stderr is
120 considered a macro, not a regular symbol (see table 94 `Header
121 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
122 Therefore std:: does not apply to it. It still does with fprintf.
123 Also, s/cstdio.h/cstdio/.

AD
1252002-01-03 Akim Demaille <akim@epita.fr>
126
127 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
128 for non system headers.

1302002-01-02 Akim Demaille <akim@epita.fr>
131
132 Equip the skeleton chain with location tracking, runtime trace,
133 pure parser and scanner.
134
135 * src/parse-skel.y: Request a pure parser, locations, and prefix
136 renaming.
137 (%union): Having several members with the same type does not help
138 type mismatches, simplify.
139 (YYPRINT, yyprint): New.
140 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
141 (skel_error): this.
142 Handle locations.
143 * src/scan-skel.l: Adjust to these changes.
144 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
145 (LOCATION_PRINT, skel_control_t): New.
146

AD
1472001-12-30 Akim Demaille <akim@epita.fr>
148
149 * src/parse-skel.y: Get rid of the shift/reduce conflict:
150 replace `gb' with BLANKS.
151 * src/scan-skel.l: Adjust.
152
a4b36db4
AD
1532001-12-30 Akim Demaille <akim@epita.fr>
154
155 * src/system.h: We don't need nor want bcopy.
156 Throw away MS-DOS crap: we don't need getpid.
157 * configure.in: We don't need strndup. It was even causing
158 problems: because Flex includes the headers *before* us,
159 _GNU_SOURCE is not defined by config.h, and therefore strndup was
160 not visible.
161 * lib/xstrndup.c: New.
162 * src/scan-skel.l: Use it.
163 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
164 * src/parse-skel.y: Use %directives instead of #defines.
165

1662001-12-30 Akim Demaille <akim@epita.fr>
167
168 * src/skeleton.h: New.
169 * src/output.c (output_parser, output_master_parser): Remove, dead
170 code.
171 * src/output.h (get_lines_number, actions_output, guards_output)
172 (token_definitions_output): Prototype them.
173 * src/parse-skel.y: Add the license notice.
174 Include output.h and skeleton.h.
175 (process_skeleton): Returns void, and takes a single parameter.
176 * src/scan-skel.l: Add the license notice.
177 Include skeleton.h.
178 Don't use %option yylineno: it seems that then Flex imagines
179 REJECT has been used, and therefore it won't reallocate its
180 buffers (which makes no other sense to me than a bug). It results
181 in warnings for `unused: yy_flex_realloc'.
182

1832001-12-30 Robert Anisko <robert.anisko@epita.fr>
184
185 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
186 (MUSCLE_INSERT_PREFIX): ...to there.
187 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
188 (MUSCLE_INSERT_PREFIX): Move from here...
189
190 * src/bison.hairy: Add a section directive. Put braces around muscle
191 names. This parser skeleton is still broken, but Bison should not
192 choke on a bad muscle 'syntax'.
193 * src/bison.simple: Add a section directive. Put braces around muscle
194 names.
195
196 * src/files.h (strsuffix, stringappend): Add declarations.
197 (tab_extension): Add declaration.
198 (short_base_name): Add declaration.
199
200 * src/files.c (strsuffix, stringappend): No longer static. These
201 functions are used in the skeleton parser.
202 (tab_extension): New.
203 (compute_base_names): Use the computations done in this function
fab5b110 204 to guess if the generated parsers should have '.tab' in their
9b3add5b
RA
205 names.
206 (short_base_name): No longer static.
207
208 * src/output.c (output_skeleton): New.
209 (output): Disable call to output_master_parser, and give a try to
210 a new skeleton handling system.
211 (guards_output, actions_output): No longer static.
212 (token_definitions_output, get_lines_number): No longer static.
213
214 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
215
fab5b110 216 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
9b3add5b
RA
217 parse-skel.y.
218
219 * src/parse-skel.y: New file.
220 * src/scan-skel.l: New file.

223
224 %name-prefix is broken.
225
226 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
227 Adjust all dependencies.
228 * tests/headers.at (export YYLTYPE): Strengthen this test: use
229 %name-prefix.
230
231 Renaming yylval but not yylloc is not consistent. Now we do.
232
233 * src/bison.simple: Prefix yylloc if used.
234 * doc/bison.texinfo (Decl Summary): Document that.
235
8c9a50be
AD
2362001-12-29 Akim Demaille <akim@epita.fr>
237
238 * doc/bison.texinfo: Promote `%long-directive' over
239 `%long_directive'.
240 Remove all references to fixed-output-files, yacc is enough.

d99361e6
AD
2422001-12-29 Akim Demaille <akim@epita.fr>
243
244 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
245 user prologue. These are defaults.
246 * tests/actions.at (Mid-rule actions): Make sure the user can
247 define YYDEBUG and YYERROR_VERBOSE.

2492001-12-29 Akim Demaille <akim@epita.fr>
250
251 * src/output.c (header_output): Don't forget to export YYLTYPE and
252 yylloc.
253 * tests/headers.at (export YYLTYPE): New, make sure it does.
254 * tests/regression.at (%union and --defines, Invalid CPP headers):
255 Move to...
256 * tests/headers.at: here.

2582001-12-29 Akim Demaille <akim@epita.fr>

AD
2622001-12-29 Akim Demaille <akim@epita.fr>

272
273 Don't store the token defs in a muscle, just be ready to output it
274 on command. Now possible via `symbols'. Fixes a memory leak.
275
276 * src/output.c (token_definitions_output): New.
277 (output_parser, header_output): Use it.
278 * src/reader.c (symbols_save): Remove.
279
cce71710
AD
2802001-12-29 Akim Demaille <akim@epita.fr>
281
282 * src/bison.simple: Do not provide a default for YYSTYPE and
283 YYLTYPE before the user's prologue. Otherwise it's hardly... a
284 default.
285
82c035a8
AD
2862001-12-29 Akim Demaille <akim@epita.fr>
287
288 Mid-rule actions are simply... ignored!
289
290 * src/reader.c (readgram): Be sure to attach mid-rule actions to
291 the empty-rule associated to the dummy symbol, not to the host
292 rule.
293 * tests/actions.at (Mid-rule actions): New.
294

297 Memory leak.

AD
3012001-12-29 Akim Demaille <akim@epita.fr>
302
303 Memory leak.
304
305 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
306 since it allocates it for each state, although only one is needed.
307 (allocate_storage): Do it here.
308

311 * src/options.h, src/options.c (create_long_option_table): Rename
312 as...

326 Sorry, I don't understand exactly what it is, no better name...

3552001-12-29 Akim Demaille <akim@epita.fr>
356
357 * src/gram.h, src/gram.c (symbols): New, similar to state_table
358 and rule_table.
359 * src/reader.c (packsymbols): Fill this table.
360 Drop sprec.
361 * src/conflicts.c (resolve_sr_conflict): Adjust.
362 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
363 single table.
364 Use symbols[i]->tag instead of tags[i].

367
368 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
369 In addition, put a comment in there, to replace...

e7b8bef1
AD
3722001-12-29 Akim Demaille <akim@epita.fr>
373
374 * tests/regression.at (Web2c Actions): Blindly move the actual
375 output as expected output. The contents *seem* right to me, but I
376 can't pretend reading perfectly parser tables... Nonetheless, all
377 the other tests pass correctly, the table look OK, even though the
378 presence of `$axiom' is to be noted: AFAICS it is useless (but
379 harmless).

AD
3812001-12-29 Akim Demaille <akim@epita.fr>
382
383 * src/reader.c (readgram): Don't add the rule 0 if there were no
384 rules read. In other words, add it _after_ having performed
385 grammar sanity checks.
386 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
387
78d5bae9
AD
3882001-12-29 Akim Demaille <akim@epita.fr>
389
390 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
391 visible, and some states have now a different number.

3932001-12-29 Akim Demaille <akim@epita.fr>
394
395 * src/reader.c (readgram): Bind the initial rule's lineno to that
396 of the first rule.
397 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
398 (Solved SR Conflicts): Adjust rule 0's line number.

AD
4002001-12-29 Akim Demaille <akim@epita.fr>
401
402 Fix the `GAWK Grammar' failure.
403
404 * src/LR0.c (final_state): Initialize to -1 so that we do compute
405 the reductions of the first state which was mistakenly confused
406 with the final state because precisely final_state was initialized
407 to 0.
408 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
409 now noticed by Bison.
410 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
411 have a reduction on $default.

414
415 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
416 rule line numbers.
417 * src/closure.c (print_closure): Likewise.
418 * src/derives.c (print_derives): Likewise.
419 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
420 now.

4222001-12-29 Akim Demaille <akim@epita.fr>
423
424 * src/lalr.c (lookaheads_print): New.
425 (lalr): Call it when --trace-flag.
426 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
427 are dumped.

AD
4292001-12-29 Akim Demaille <akim@epita.fr>
430
431 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
432 when walking through ritem, even via rule->rhs.
433 * src/reduce.c (dump_grammar, useful_production, reduce_output)
434 (useful_production, useless_nonterminals): Likewise.
435 (reduce_grammar_tables): Likewise, plus update nritems.
436 * src/nullable.c (set_nullable): Likewise.
437 * src/lalr.c (build_relations): Likewise.
438 * tests/sets.at (Nullable): Adjust.
439 Fortunately, now, the $axiom is no longer nullable.

4412001-12-29 Akim Demaille <akim@epita.fr>
442
443 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
444 the 0-sentinel.
445 * src/gram.c (ritem_longest_rhs): Likewise.

457 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
458 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
459 Sparc, as they were causing more porting problems than the
460 (minor) performance improvement was worth.
461

467 0-sentinel. See below.
468 Use -1 as separator, not 0.
469 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
470 Rely on -1 as separator in yyrhs, instead of 0.
471 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
472 twice `Now at end of input', therefore there are two lines less to
473 expect.

484 is reached by eoftoken.
485 (insert_start_shifting_state, insert_eof_shifting_state)
486 (insert_accepting_state, augment_automaton): Remove, since now
487 these states are automatically computed from the initial state.
488 (generate_states): Adjust.
489 * src/print.c: When reporting a rule number to the user, substract
490 1, so that the axiom rule is rule 0, and the first user rule is 1.
491 * src/reduce.c: Likewise.
492 * src/print_graph.c (print_core): For the time being, just as for
493 the report, depend upon --trace-flags to dump the full set of
494 items.
495 * src/reader.c (readgram): Once the grammar read, insert the rule
496 0: `$axiom: START-SYMBOL $'.
497 * tests/set.at: Adjust: rule 0 is now displayed, and since the
498 number of the states has changed (the final state is no longer
499 necessarily the last), catch up.

503 Try to make the use of the eoftoken valid. Given that its value
504 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
505 is used instead of > 0 where appropriate, (ii), depend upon nritems
506 instead of the 0-sentinel.
507
508 * src/gram.h, src/gram.c (nritems): New.
509 Expected to be duplication of nitems, but for the time being...

520 reductions, then output the report anyway if requested, then die.
521 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
522 * src/reader.c (eoftoken): New.
523 (parse_token_decl): If the token being defined has value `0', it
524 is the eoftoken.
525 (packsymbols): No longer hack `tags' to insert `$' by hand.
526 Be sure to preserve the value of the eoftoken.
527 (reader): Make sure eoftoken is defined.
528 Initialize nsyms to 0: now eoftoken is created just like the others.
529 * src/print.c (print_grammar): Don't special case the eof token.
530 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
531 lie anyway, albeit pleasant.
532 * tests/calc.at: Exercise error messages with eoftoken.
533 Change the grammar so that empty input is invalid.

623 (copy_action): action_line is the first line, not the last.

625 the switch/case/break flesh.
626 Don't parse the user action that might follow the guard, let...

672 As much as possible, depend upon nlookaheads, instead of the
673 `lookaheadsp' member of the following state (since lookaheads of

938 Work around Autotest bugs.
939
940 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
941 frame, because Autotest understand lines starting with a `+' as
942 traces from the shell. Then, they are not processed properly.
943 Admittedly an Autotest bug, but we don't have time to wait for

959 nonterminal.
960 * tests/regression.at: Adjust some tests.
961 * src/print_graph.c (print_core): Complete the set of items via
962 closure. The next-to-final and final states are still unsatisfying,
963 but that's to be addressed elsewhere.
964 No longer output the rule numbers, but do output the state number.
965 A single loop for the shifts + gotos is enough, but picked a
966 distinct color for each.
967 (print_graph): Initialize and finalize closure.
