3 java: finish fixing parser stack popping bug.
4 * NEWS (2.5): Document.
5 * data/lalr1.java (YYParser::YYStack::pop): Fix off-by-one error
6 in clearing the location stack. Also fix pop function that
7 accepts no arguments.

11 java: fix parser stack popping bug.
12 Reported at
13 <http://lists.gnu.org/archive/html/bug-bison/2011-02/msg00005.html>.
14 * THANKS (Angelo Borsotti): Add.
15 * data/lalr1.java (YYParser::YYStack::pop): Fix off-by-one error
16 in clearing the value stack. Previously, the top element of the
17 stack wasn't cleared and so the value was not garbage collected.
18
19 2011-03-06 Joel E. Denny <joeldenny@joeldenny.org>
20
21 doc: cite publication for LAC.
22 * doc/bison.texinfo (LAC): Here.
23
24 2011-03-06 Joel E. Denny <joeldenny@joeldenny.org>
25
26 doc: clean up terminology for mysterious conflicts.
27 * doc/bison.texinfo (Mystery Conflicts): Rename node to...
28 (Mysterious Conflicts): ... this, which is already the section
29 title and the name used in the index. Update all cross-references
30 to this node. Also, don't imply that R/R conflicts are the only
31 kind of mysterious conflict.
32
33 2011-03-06 Joel E. Denny <joeldenny@joeldenny.org>
34
35 lr.default-reductions: rename "all" value to "full".
36 States that shift the error token do not have default reductions,
37 and GLR disables some default reductions, so "all" was a misnomer.
38 * doc/bison.texinfo (%define Summary): Update.
39 (Default Reductions): Update.
40 * src/print.c (print_reductions): Update.
41 * src/reader.c (prepare_percent_define_front_end_variables):
42 Update.
43 * src/tables.c (action_row): Update.
44 * tests/input.at (%define enum variables): Update.
45 * tests/reduce.at (%define lr.default-reductions): Update.
46
47 2011-03-06 Joel E. Denny <joeldenny@joeldenny.org>
48
49 doc: create a new Tuning LR section in the manual.
50 And clean up all other documentation of the features described
51 there.
52 * NEWS (2.5): Tweak wording of lr.type and parse.lac entries a
53 bit, update the cross-references to the manual, and point out that
54 LAC has caveats. Don't be so adamant that IELR+LAC=canonical LR.
55 That is, as the referenced section in the manual documents, LAC
56 does not fix infinite parsing loops on syntax errors.
57 * doc/bison.texinfo: Consistently drop the "(1)" suffix from LALR,
58 IELR, and LR in @cindex.
59 (%define Summary): Condense the entries for lr.default-reductions,
60 lr.keep-unreachable-states, lr.type, and parse.lac into brief
61 summaries, and cross-reference the appropriate subsections of
62 Tuning LR. For parse.lac, mention that it's only implemented for
63 deterministic parsers in C. In parse.error entry, mention LAC,
64 and add cross-reference to the LAC section.
65 (Error Reporting): When mentioning parse.error, mention LAC, and
66 add cross-reference to the LAC section.
67 (Tuning LR): New section with an extended version of the
68 documentation removed from %define Summary. Change all
69 cross-references in the manual to point here instead of there.
70 (Calc++ Parser): When mentioning parse.error, mention LAC, and add
71 cross-reference to the LAC section.
72 (Table of Symbols): In %error-verbose entry, add cross-reference
73 to Error Reporting.
74 (Glossary): Capitalize entry titles consistently. Add definitions
75 for "defaulted state" and "unreachable state". Expand IELR
76 acronym in IELR's entry.
77
78 2011-02-20 Joel E. Denny <joeldenny@joeldenny.org>
79
80 doc: add bibliography to manual.
81 * doc/bison.texinfo (Mystery Conflicts): Cross-reference
82 bibliography instead of citing publications directly.
83 (Generalized LR Parsing): Likewise.
84 (Bibliography): New section. Not all entries are cross-referenced
85 yet, but that will come in future patches.
86
87 2011-02-19 Joel E. Denny <joeldenny@joeldenny.org>
88
89 java: test and document previous bug fix.
90 * NEWS (2.5): Document it.
91 * tests/java.at (_AT_DATA_JAVA_CALC_Y): To one of the yyerror
92 invocations, pass a location that spans multiple tokens. Change
93 yyerror to report all of a location rather than just the begin
94 position. Extend yylex and Position to count tokens on a line.
95 Remove getHashCode as it's unused. Update all expected output.
96
97 2011-02-19 Bernd Kiefer <kiefer@dfki.de> (tiny change)
98
99 java: fix location handling bug.
100 Reported at
101 <http://lists.gnu.org/archive/html/bison-patches/2011-02/msg00005.html>.
102 * data/lalr1.java (YYParser::yylloc): For non-empty RHS, fix
103 reversed access to location stack.
104 * THANKS (Bernd Kiefer): Add.
105
106 2011-02-13 Joel E. Denny <joeldenny@joeldenny.org>
107
108 doc: fix some minor inconsistencies.
109 * doc/bison.texinfo (%define Summary): Fix mislabeled entry for
110 lex_symbol.
111 (%code Summary): For consistency with the variable list in the
112 %define Summary, enclose the list of %code qualifiers in a table
113 instead of an itemize.
114
115 2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
116
117 doc: clean up new subsections in manual.
118 * doc/bison.texinfo (%define Summary): Reword so it reads well as
119 a separate section. For example, add an intro, and move most of
120 the text outside of the @deffn so it is not indented so far.
121 (%code Summary): Likewise.
122 (Table of Symbols): Reword %code entry to match the %code entry in
123 Decl Summary.
124
125 2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
126
127 doc: finish splitting apart the manual's Decl Summary section.
128 Suggested by Akim Demaille at
129 <http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00013.html>.
130 * doc/bison.texinfo (Decl Summary): Extract most of the %define
131 entry into...
132 (%define Summary): ... this new subsection, and update all
133 cross-references. For readability of the patches, rewriting of
134 the text so it makes sense as a separate subsection will come in a
135 later patch. Moreover, the majority of the text describing the
136 various new LR features should likely move to another new section
137 somewhere.
138
139 2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
140
141 doc: begin to split apart the manual's Decl Summary section.
142 Discussed in thread starting at
143 <http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00013.html>.
144 * doc/bison.texinfo (Decl Summary): Extract most of the %code
145 entry into...
146 (%code Summary): ... this new subsection, and update all
147 cross-references. For readability of the patches, rewriting of
148 the text so it makes sense as a separate subsection will come in a
149 later patch.
150
151 2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
152
153 doc: clean up naming of various Bison files.
154 The Bison manual's names for various files associated with a Bison
155 parser has devolved into inconsistency. This patch makes the
156 naming consistent for the most important files. First, it chooses
157 "grammar file" over "input file". The former appears to be more
158 traditional in the Bison manual, and Bison has other input
159 files (skeletons). Second, it chooses "parser implementation
160 file" over names like "parser file", "parser source file", "parser
161 source code file", and "parser output file". The new name makes
162 it clearer where Bison generates the main parser implementation,
163 and it is easily distinguishable from "parser header file".
164 * doc/bison.texinfo: Implement throughout.
165
166 2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
167
168 doc: give credit to more of Bison's developers.
169 * doc/bison.texinfo (Introduction): Don't imply that only Robert
170 Corbett, Richard Stallman, and Wilfred Hansen have contributed to
171 Bison. However, I don't have time to write a full history, so
172 just point readers to THANKS and ChangeLog.
173
174 2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
175
176 doc: document experimental features better.
177 * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
178 LR(1) are experimental. Mention Java. Normally experimental
179 features probably shouldn't be mentioned in the introduction.
180 However, if Bison's limitations to LALR(1), C, and C++ are so
181 important that they should be mentioned here, then it's important
182 to point out that Bison is beginning to escape those limitations.
183 Moreover, these particular experimental features have very little
184 chance of being removed.
185 * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
186 experimental.
187
188 2011-01-29 Joel E. Denny <joeldenny@joeldenny.org>
189
190 Do not allow identifiers that start with a dash.
191 This cleans up our previous fixes for a bug whereby Bison
192 discarded `.field' in `$-1.field'. The previous fixes were less
193 restrictive about where a dash could appear in an identifier, but
194 the restrictions were hard to explain. That bug was reported and
195 this final fix was originally suggested by Paul Hilfinger. This
196 also fixes a remaining bug reported by Paul Eggert whereby Bison
197 parses `%token ID -123' as `%token ID - 123' and handles `-' as an
198 identifier. Now, `-' cannot be an identifier. Discussed in
199 threads beginning at
200 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
201 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
202 * NEWS (2.5): Update entry describing the dash extension to
203 grammar symbol names. Also, move that entry before the named
204 references entry because the latter mentions the former.
205 * doc/bison.texinfo (Symbol): Update documentation for symbol
206 names. As suggested by Paul Eggert, mention the effect of periods
207 and dashes on named references.
208 (Decl Summary): Update documentation for unquoted %define values,
209 which, as a side effect, can no longer start with dashes either.
210 * src/scan-code.l (id): Implement.
211 * src/scan-gram.l (id): Implement.
212 * tests/actions.at (Exotic Dollars): Extend test group to exercise
213 bug reported by Paul Hilfinger.
214 * tests/input.at (Symbols): Update test group, and extend to
215 exercise bug reported by Paul Eggert.
216 * tests/named-refs.at (Stray symbols in brackets): Update test
217 group.
218 ($ or @ followed by . or -): Likewise.
219 * tests/regression.at (Invalid inputs): Likewise.
220
221 2011-01-24 Joel E. Denny <joeldenny@joeldenny.org>
222
223 * data/yacc.c: Fix last apostrophe warning from xgettext.
224
225 2011-01-09 Paul Eggert <eggert@cs.ucla.edu>
226
227 Fix minor problems encountered by a fresh bootstrap.
228 * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
229 as they confuse xgettext, which tries to parse them as C character
230 constants in a preprocessor directive.
231 * data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as
232 that expression might not promote to int on some platforms.
233 * src/parse-gram.c, src/parse-gram.h: Regenerate.
234
235 2011-01-09 Joel E. Denny <joeldenny@joeldenny.org>
236
237 Improve error messages for `$' or `@' followed by `.' or `-'.
238 Previously, for this special case of an invalid reference, the
239 usual "symbol not found in production:" was printed. However,
240 because the symbol name was parsed as the empty string, that
241 message was followed immediately by a newline instead of a symbol
242 name. In reality, this is a syntax error, so the reference is
243 invalid regardless of the symbols actually appearing in the
244 production. Discussed at
245 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
246 * src/scan-code.l (parse_ref): Report the above case as a syntax
247 error. Other than that, continue to handle this case like any
248 other invalid reference that Bison manages to parse because
249 "possibly meant" messages can still be helpful to the user.
250 * tests/named-refs.at ($ or @ followed by . or -): New test group.
251
252 2011-01-08 Joel E. Denny <joeldenny@joeldenny.org>
253
254 doc: don't use @acronym.
255 Lately, many GNU packages are dropping it. See
256 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00003.html>.
257 * doc/bison.texinfo: Remove all uses.
258
259 2011-01-05 Alex Rozenman <rozenman@gmail.com>
260
261 Do not allow identifiers that start with a negative number.
262 Reported by Paul Hilfinger as a side effect of named references
263 support at
264 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>.
265 Suggested by Paul Eggert.
266 * src/scan-code.l ({letter}, {id}): Adjust lexical definitions.
267 * src/scan-gram.l ({letter}, {id}): Likewise.
268
269 2011-01-03 Joel E. Denny <joeldenny@joeldenny.org>
270
271 * ChangeLog (2011-01-02): improve description.
272
273 2011-01-03 Joel E. Denny <joeldenny@joeldenny.org>
274
275 maint: don't update copyright years in bootstrap.
276 * .x-update-copyright: Add entry for bootstrap.
277 * bootstrap: Remove 2011 from copyright years. The bootstrap
278 version we're currently using comes from an older version of
279 gnulib.
280 * bootstrap.conf (bootstrap_sync): Add comments explaining this
281 issue.
282
283 2011-01-02 Joel E. Denny <joeldenny@joeldenny.org>
284
285 maint: run "make update-copyright".
286
287 2011-01-02 Joel E. Denny <joeldenny@joeldenny.org>
288
289 maint: prepare to use year ranges in copyright notices.
290 * README (Copyright statements): New section explaining the range
291 notation. The GNU maintainers document requires this explanation:
292 <http://www.gnu.org/prep/maintain/maintain.html#Copyright-Notices>.
293 I copied our explanation from coreutils.
294 * build-aux/update-b4-copyright: Revert 2010-06-17 changes that
295 disabled Bison's automated use of ranges.
296 * cfg.mk (update-copyright-env): Likewise.
297
298 2011-01-02 Joel E. Denny <joeldenny@joeldenny.org>
299
300 Correct my email address.
301 * ChangeLog: In all recent entries.
302 * THANKS (Joel E. Denny): Here.
303
304 2010-12-19 Joel E. Denny <joeldenny@joeldenny.org>
305
306 doc: cleanup.
307 * NEWS (2.5): Try to sort entries according to how interesting
308 users might find them.
309
310 2010-12-19 Joel E. Denny <joeldenny@joeldenny.org>
311
312 doc: cleanup.
313 * NEWS (2.5): Make some minor improvements to wording, and format
314 entries more consistently.
315 * doc/bison.texinfo (Language and Grammar): Point out that IELR
316 and canonical LR are experimental features.
317 (Decl Summary): In list of %define variables, make wording more
318 consistent. Improve discussion of using LALR for GLR.
319
320 2010-12-19 Joel E. Denny <joeldenny@joeldenny.org>
321
322 parse.lac: document.
323 * NEWS (2.5): Add entry for LAC, and mention LAC in entry for
324 other corrections to verbose syntax error messages.
325 * doc/bison.texinfo (Decl Summary): Rewrite entries for
326 lr.default-reductions and lr.type to be clearer, to mention
327 %nonassoc's effect on canonical LR, and to mention LAC. Add entry
328 for parse.lac.
329 (Glossary): Add entry for LAC.
330
331 2010-12-11 Joel E. Denny <joeldenny@joeldenny.org>
332
333 parse.lac: implement exploratory stack reallocations.
334 * data/yacc.c: Rename %define variable parse.lac.es-capacity to
335 parse.lac.es-capacity-initial. Accept parse.lac.memory-trace
336 with values of "failures" (default) or "full".
337 (b4_declare_parser_state_variables): Add yyesa, yyes, and
338 yyes_capacity variables.
339 (YYSTACK_USE_ALLOCA): Ignore it if LAC requested.
340 (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if
341 LAC requested.
342 (YYCOPY_NEEDED): New cpp macro.
343 (YYCOPY): Define if LAC requested.
344 (yy_lac_stack_realloc): New function implementing stack
345 reallocations. Use YYMAXDEPTH for maximum stack size given that
346 the stack should never need to grow larger than the main state
347 stack needs to grow without LAC.
348 (YY_LAC_ESTABLISH): Update yy_lac invocation.
349 (yy_lac): Add arguments for exploratory stack memory data
350 recorded in the main parser. Invoke yy_lac_stack_realloc when
351 reallocation is necessary.
352 (yysyntax_error): Add the same new arguments and pass them to
353 yy_lac.
354 (yypstate_delete): Free yyes if necessary.
355 (yyesa, yyes, yyes_capacity): #define these to yypstate members
356 in the case of push parsing.
357 (yyparse, yypush_parse): Initialize yyes and yyes_capacity.
358 Update yysyntax_error invocations. At yyreturn, free yyes if
359 necessary.
360 * src/parse-gram.y: %define parse.lac full.
361 * tests/input.at (LAC: errors for %define): Extend for
362 parse.lac-memory-trace.
363 * tests/regression.at (LAC: Exploratory stack): Extend to check
364 that stack reallocs happen when expected.
365 (LAC: Memory exhaustion): Update to use YYMAXDEPTH and
366 parse.lac.es-capacity-initial.
367
368 2010-12-11 Joel E. Denny <joeldenny@joeldenny.org>
369
370 parse.lac: implement as %define variable.
371 LAC = lookahead correction. See discussion at
372 <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>.
373 However, one point there must be corrected: because of %nonassoc,
374 LAC is *not* always redundant for lr.type=canonical-lr.
375 * data/yacc.c: Accept values of "none" (default) or "full" for
376 parse.lac. Accept %define parse.lac.es-capacity to specify
377 capacity of LAC's temporary exploratory stack. It defaults to 20
378 and, for now, will not grow dynamically.
379 (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for
380 parse.lac!=none.
381 (YYBACKUP): Invoke YY_LAC_DISCARD.
382 (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke
383 yy_lac and track when it needs to be invoked
384 (yy_lac): New function that, given the current stack, determines
385 whether a token can eventually be shifted. Return status mimics
386 yyparse return status.
387 (yysyntax_error): Change yystate argument to yyssp so stack top
388 can be passed to yy_lac. If LAC is requested, build expected
389 token list by invoking yy_lac for every token instead of just
390 checking the current state for lookaheads. Return 2 if yy_lac
391 exhausts memory.
392 (yyparse, yypush_parse): Use local variable yy_lac_established and
393 cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
394 Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
395 is requested.
396 * tests/conflicts.at (%nonassoc and eof): Extend to check the
397 effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
398 (parse.error=verbose and consistent errors): Likewise.
399 (LAC: %nonassoc requires splitting canonical LR states): New test
400 group demonstrating how LAC can fix canonical LR.
401 * tests/input.at (LAC: Errors for %define): New test group.
402 * tests/regression.at (LAC: Exploratory stack): New test group.
403 (LAC: Memory exhaustion): New test group.
404
405 2010-11-21 Joel E. Denny <joeldenny@joeldenny.org>
406
407 build: use gnulib's new bootstrap_sync option.
408 Now, whenever we update bison's copy of gnulib, bootstrap will
409 update itself the next time it's run.
410 * bootstrap: Copy from latest gnulib for bootstrap_sync support.
411 * bootstrap.conf (bootstrap_sync): Set to true.
412 * gnulib: Update to latest so bootstrap is in sync now.
413
414 2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
415
416 yysyntax_error: fix for consistent error with lookahead.
417 * NEWS (2.5): Document.
418 * data/yacc.c (yysyntax_error): In a verbose syntax error
419 message while in a consistent state with a default action (which
420 must be an error action given that yysyntax_error is being
421 invoked), continue to drop the expected token list, but don't
422 drop the unexpected token unless there actually is no lookahead.
423 Moreover, handle that internally instead of returning 1 to tell
424 the caller to do it. With that meaning of 1 gone, renumber
425 return codes more usefully.
426 (yyparse, yypush_parse): Update yysyntax_error usage. Most
427 importantly, set yytoken to YYEMPTY when there's no lookahead.
428 * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
429 unexpected token unless there actually is no lookahead.
430 * data/lalr1.cc (yy::parser::parse): If there's no lookahead,
431 pass yyempty_ not yyla.type to yysyntax_error_.
432 (yy::parser::yysyntax_error_): Again, don't drop the unexpected
433 token unless there actually is no lookahead.
434 * data/lalr1.java (YYParser::parse): If there's no lookahead,
435 set yytoken to yyempty_ before invoking yysyntax_error.
436 (YYParser::yysyntax_error): Again, don't drop the unexpected
437 token unless there actually is no lookahead.
438 * tests/conflicts.at (parse.error=verbose and consistent
439 errors): Extend test group to further reveal how the previous
440 use of the simple "syntax error" message was too general. Test
441 yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
442 failure.
443 * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
444 to...
445 * tests/local.at: ... here.
446 (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
447 (AT_BISON_OPTION_POPDEFS): Pop it.
448 (AT_FULL_COMPILE): Extend to handle Java.
449
450 2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
451
452 yysyntax_error: more preparation for readability of next patch.
453 There are no behavioral changes here.
454 * data/glr.c (yyreportSyntaxError): Reorganize.
455 * data/lalr1.cc (yy::parser::yysyntax_error_): Reorganize.

459 2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
460
461 yysyntax_error: prepare for readability of next patches.
462 These are purely whitespace changes that result in ugly code
463 but that make the next couple of patches much easier to read.
464 * data/glr.c (yyreportSyntaxError): Reindent.
465 * data/lalr1.cc (yy::parser::yysyntax_error_): Reindent.
466 * data/lalr1.java (YYParser::yysyntax_error): Reindent.
467 * data/yacc.c (yysyntax_error): Reindent.
468
469 2010-10-31 Joel E. Denny <joeldenny@joeldenny.org>
470
471 Fix memory leak.
472 * src/output.c (prepare_rules): Free temporary array.
473
474 2010-10-31 Joel E. Denny <joeldenny@joeldenny.org>
475
476 yysyntax_error: improve invocation readability.
477 * data/yacc.c (yyparse, yypush_parse): For yysyntax_error
478 invocation, get rid of the while loop, which is misleading
479 because there are really at most two iterations.
480
481 2010-10-31 Joel E. Denny <joeldenny@joeldenny.org>
482
483 * ChangeLog: Correct some errors in previous entries.
484
485 2010-10-17 Joel E. Denny <joeldenny@joeldenny.org>
486
487 maint: re-anchor all .gitignore entries.
488 * bootstrap: Copy from gnulib's latest for the fix to
489 automatically anchor entries it constructs.
490 * gnulib: Update to latest just so it has the same bootstrap.
491 * .gitignore, build-aux/.gitignore, doc/.gitignore:
492 * lib/.gitignore, m4/.gitignore, po/.gitignore:
493 * runtime-po/.gitignore: Re-anchor all entries.
494
495 2010-10-08 Paul Eggert <eggert@cs.ucla.edu>
496
497 Fix portability problem on OpenBSD 4.7.
498
499 Jim Meyering reported this in
500 <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>.
501 * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h,
502 not _STDLIB_H. EXIT_SUCCESS has been defined by the standard
503 for quite some time.
504 * src/parse-gram.c, src/parse-gram.h: Regenerate.
505 * tests/regression.at: Tamper with the renamed witness.
506
507 Adjust to recent changes to gnulib bootstrap.
508
509 * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
510 * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
511 * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
512 * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
513 anymore and don't know of anybody else who does. If someone needs
514 these files, they can resurrect them.
515 * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
516 * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
517 Omit leading '/', since bootstrap omits it.
518 Adjust file names to match current contents better.
519 * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
520 installed just for us.
521 * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
522 glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
523 needed somehow. Don't have time to look into why.
524 (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
525 the GNU malloc behavior, where malloc (0) != NULL unless we're
526 out of storage? If not, we can omit malloc-gnu; but for now I left
527 it in to be safe.
528 (vc_ignore): Remove.
529 (gnulib_mk_hook): New function.
530 * README-hacking: Renamed from HACKING, since gnulib bootstrap now
531 uses that convention.
532
533 2010-09-09 Paul Hilfinger <hilfinger@cs.berkeley.edu>
534
535 * data/glr.c (yySymbol): Define as int to avoid compiler warnings about
536 possible change of value.
537
538 2010-09-08 Paul Hilfinger <hilfinger@cs.berkeley.edu>
539
540 * data/glr.c (yy_reduce_print): Change yyrhsVals to yyvsp to remove
541 compiler errors when using %debug.
542 Add declaration of yylow when locations in use to avoid compilation
543 error.
544 (yyglrReduce): Conditionalize message "Parse ... rejected by rule..."
545 on whether we are in split mode, for consistency with behavior of
546 non-GLR parsing.
547
548 2010-09-01 Akim Demaille <demaille@gostai.com>
549
550 Address GCC warnings about shadowed local variables (yyflag).
551 * data/glr.c (YYCHK): Rename yyflag as yychk_flag.
552 (yyprocessOneStack): Reduce the scope of yyaction, yyconflicts,
553 yyrule, and yyflag.
554
555 2010-08-05 Joel E. Denny <joeldenny@joeldenny.org>

576
577 2010-08-01 Joel E. Denny <joeldenny@joeldenny.org>
578
579 -Werror: fix for rules useless in parser after conflicts.
580 * NEWS (2.4.3): Document fix.
581 * src/complain.c (error_message): Extend to handle incomplete
582 error messages so warn and warn_at can be used in more cases.
583 * src/gram.c (grammar_rules_useless_report): Use warn_at so that
584 -Werror is always obeyed.
585 * src/reduce.c (reduce_print): Use warn so that the "warnings
586 being treated as errors" message is printed consistently before
587 the first warning message. This makes testing easier.
588 * tests/local.at (AT_BISON_WERROR_MSG): New macro.
589 (AT_BISON_CHECK_NO_XML): Extend to check -Werror and
590 --warnings=error when warnings appear in bison's stderr.
591
592 2010-07-29 Joel E. Denny <joeldenny@joeldenny.org>
593

607 translatable strings.
608
609 2010-07-25 Joel E. Denny <joeldenny@joeldenny.org>
610
611 build: fix our adjustments for gnulib files in lib.
612 * configure.ac: For prepending lib/ to the values of config
613 variables, fix detection of empty values. Also, due to recent
614 gnulib changes, add LIBUNISTRING_UNITYPES_H and
615 LIBUNISTRING_UNIWIDTH_H to the list of those variables.
616
617 2010-07-25 Joel E. Denny <joeldenny@joeldenny.org>

786 location.hh, and do not produce location.hh and position.hh.
787 * tests/calc.at (YYLLOC_DEFAULT): Use YYRHSLOC.
788 Check that glr.cc supports user defined location_type.

800 (AT_TEST_SYNCLINE): Remove GCC 4.5 protection which is already
801 taken care of in AT_SYNCLINES_COMPILE.
802
803 2010-05-04 Akim Demaille <demaille@gostai.com>

808 variable location_type, rather, use b4_percent_define_get with a
809 default argument where its value is needed.
810 * data/lalr1.cc: Do not load location.cc (which outputs both
811 location.hh and position.hh) if the user defined location_type.
812 Do not include location.hh either.

821 tests: fix %printer.
822 Currently, there is no check that %printer ... <foo> (nor
823 %destructor) is about an existing <foo> type. This C++ test had
824 it wrong (<::std::string> vs. <std::string>).
825

827 pretty-printing of lists into something better for parser traces.
828 Update the expected output.

830
831 2010-05-04 Akim Demaille <demaille@gostai.com>
832
833 lalr1.cc: location_type: make sure we don't depend on loc.(begin|end).
834 * tests/calc.at (Span): Instead of begin/end, as in the built-in
835 location class, use first and last.
836 Define YYLLOC_DEFAULT to adjust to these changes.
837 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Adjust to the
838 location_type changes.

840 2010-05-01 Joel E. Denny <joeldenny@joeldenny.org>
841
842 tests: fix maintainer-xml-check.
843 * data/xslt/xml2dot.xsl (xsl:template match="bison-xml-report"):
844 Update output to include comments now produced by --graph.
845 (xsl:template match="automaton"): As for --graph, name the
846 digraph after the grammar file.
847 * src/print-xml.c (escape_bufs): Enlarge array.
848 (print_xml): Add bug-report and url attributes to
849 bison-xml-report element.
850
851 2010-05-01 Joel E. Denny <joeldenny@joeldenny.org>
852
853 In DOT output, convert from "/*" comments to "//" comments.

864 2010-04-30 Joel E. Denny <joeldenny@joeldenny.org>
865
866 Revert 2009-12-30 change for undefined %prec token complaints.
867 That is, keep them as warnings because that should be sufficient
868 to satisfy POSIX without creating backward compatibility issues.
869 Suggested by Richard Stallman at

1030 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
1031
1032 tests: fix maintainer-xml-check for recent changes.
1033 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Use
1034 AT_BISON_CHECK_NO_XML rather than AT_BISON_CHECK because an
1035 output file whose name conflicts with a previous output file
1036 is now never generated.
1037
1038 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
1039
1040 portability: fix several issues with M4 subprocess.
1041
1042 M4's output pipe was not being drained upon fatal errors during
1043 scan_skel. As a result, broken-pipe messages from M4 were seen
1044 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
1045 failure in the test suite. The problem was that, on platforms
1046 where the default disposition for SIGPIPE is ignore instead of
1047 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
1048 then reported it. However, there's some sort of race condition,
1049 because the new test group occasionally succeeded.
1050 Reported by Albert Chin at
1051 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
1052
1053 There were also problems with the test suite livelocking on
1054 Tru64 5.1b. Reported by Didier Godefroy at
1055 <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
1056 Switching to create_pipe_bidi suggested by Akim Demaille.
1057
1058 To attempt to solve both of these problems, switch to gnulib's
1059 create_pipe_bidi and register M4 process as a slave. Along the
1060 way, clean up file name conflict handling, which was affected by
1061 the broken-pipe problem before the switch.
1062 * NEWS (2.4.2): Document.
1063 * THANKS (Didier Godefroy): Add.
1064 * bootstrap.conf (gnulib_modules): Add pipe.
1065 * gnulib: Update to latest to make sure we have all the latest
1066 fixes.

1068 subpipe.c.
1069 * po/POTFILES.in (lib/subpipe.c): Remove.
1070 * src/files.c (compute_output_file_names): Update invocations
1071 of output_file_name_check.
1072 (output_file_name_check): In the case that the grammar file
1073 would be overwritten, use complain instead of fatal, but replace
1074 the output file name with /dev/null. Use the /dev/null solution
1075 for the case of two conflicting output files as well because it
1076 seems safer in case Bison one day tries to open both files at
1077 the same time.
1078 * src/files.h (output_file_name_check): Update prototype.
1079 * src/output.c (output_skeleton): Use create_pipe_bidi and
1080 wait_subprocess. Assert that scan_skel completely drains the
1081 pipe.
1082 * src/scan-skel.l (at_directive_perform): Update
1083 output_file_name_check invocation.
1084 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the

1153 Fix some comments concerning LR(0) versus LALR(1).
1154
1155 Stop equating LR(0) with nondeterminism and LALR(1) with
1156 determinism. That is, if all states are consistent, then LR(0)
1157 tables are deterministic. On the other hand, LALR(1) tables
1158 might be nondeterministic before conflict resolution, and GLR
1159 permits LALR(1) tables to remain nondeterministic.

1199 portability: `<' and `>' are not always defined on addresses.
1200 Specifically, don't sort objects by their memory addresses when
1201 they're not allocated in the same array or other object. Though
1202 I haven't found a test case where that fails on my platform, C
1203 says the behavior is undefined.

1224 Fix handling of yychar manipulation in user semantic actions.
1225 The problem was that yacc.c didn't always update the yychar
1226 translation afterwards. However, other skeletons appear to be
1227 fine. glr.c appears to already translate yychar before every
1228 use. lalr1.cc does not define yychar and does not document its
1229 replacement, yyla, for users. It does provide yyclearin, but
1230 that does not manipulate yyla and thus requires no translation
1231 update. In lalr1.java, yychar is out of scope during semantic
1232 actions.
1233 * NEWS (2.5): Document.
1234 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
1235 yytoken here.
1236 (yyparse, yypush_parse): Instead, translate before every use of
1237 yytoken, and add comments explaining this approach.
1238 * tests/actions.at (Destroying lookahead assigned by semantic
1239 action): New test group checking that translation happens before
1240 lookahead destructor calls at parser return. Previously,
1241 incorrect destructors were called.
1242 * tests/conflicts.at (parse.error=verbose and consistent
1243 errors): New test group checking that translation happens at
1244 syntax error detection before the associated verbose error
1245 message and the associated lookahead destructor calls. While
1246 the destructor call is fixed by this patch, the verbose error
1247 message is currently incorrect due to another bug (see
1248 comments in test group), so this is an expected failure for now.

1441 yysyntax_error: avoid duplicate lookahead collection.
1442 Except when memory reallocation is required, this change
1443 eliminates the need to invoke yysyntax_error twice and thus to
1444 repeat the collection of lookaheads. It also prepares for
1445 future extensions that will make those repetitions more
1446 expensive and that will require additional memory management in
1447 yysyntax_error. Finally, it fixes an obscure bug already
1448 exercised in the test suite.
1449 * data/yacc.c (yysyntax_error): Add arguments for message
1450 buffer variables stored in the parser. Instead of size, return
1451 status similar to yyparse status but indicating success of
1452 message creation. Other than the actual reallocation of the
1453 message buffer, import and clean up memory management code
1454 from...
1455 (yyparse, yypush_parse): ... here.
1456 * tests/regression.at (parse.error=verbose overflow): No longer
1457 an expected failure.
1458
1459 2009-09-23 Joel E. Denny <jdenny@clemson.edu>
1460
1461 yysyntax_error: test memory management more.
1462 * tests/atlocal.in (NO_WERROR_CFLAGS): New cpp macro.
1463 * tests/regression.at (parse.error=verbose and
1464 YYSTACK_USE_ALLOCA): New test group.
1465 (parse.error=verbose overflow): New test group that reveals an
1466 obscure bug. Expected fail for now.
1467
1468 2009-10-04 Joel E. Denny <jdenny@clemson.edu>
1469
1470 benchmarks: use %debug consistently among grammars.
1471 * etc/bench.pl.in (generate_grammar_triangular): Do not activate
1472 %debug by default. It can affect the timings even if yydebug=0.
1473 (generate_grammar_calc): For consistency with other grammars,
1474 use YYDEBUG environment variable to set yydebug.
1475
1476 2009-10-03 Joel E. Denny <jdenny@clemson.edu>
1477
1478 Remove dead code.
1479 * src/symtab.c (symbol_pack): Here because every symbol's number
1480 is always defined by this time.
1481

1490 Reported by Jim Meyering.
1491 * src/Sbitset.h (SBITSET__INDEX__CONVERSION_SPEC): New, "zu"
1492 because Sbitset__Index is size_t.
1493 * src/Sbitset.c (Sbitset__fprint): Use it instead of %d.
1494
1495 2009-09-27 Joel E. Denny <jdenny@clemson.edu>

1610 lalr1.cc: syntax_error as exceptions.
1611 It is common to use sort of factories in the user actions. These
1612 factories may check some "syntactic" constraints that are not
1613 enforced by the grammar itself. This is possible using YYERROR
1614 within the action itself. Provide the user with a means to throw
1615 a syntax_error exception.

1779 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
1780 Avoid compiler warning.
1781
1782 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
1783
1784 tests: use perl for printing special sequences to files.
1785 And skip tests if perl is not available. This is better than
1786 playing tricks with shell portability. Suggested by Akim
1787 Demaille.
1788 * tests/input.at (Bad character literals): Use it here for
1789 omitting final newlines.
1790 (Bad escapes in literals): Use it here for special characters.
1791
1792 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
1793
1794 tests: show a use of %define lr.default-reductions "consistent"
1795 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
1796 prevents the omission of expected tokens for %error-verbose.
1797

1799
1800 tests: portability fix.

1803
1804 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
1805
1806 Actually handle the yytable zero value correctly this time.
1807 * data/bison.m4 (b4_integral_parser_tables_map): Don't mention
1808 zero values in the YYTABLE comments.
1809 * data/glr.c (yytable_value_is_error): Don't check for zero
1810 value.
1811 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
1812 * data/yacc.c (yytable_value_is_error): Likewise.
1813 * data/lalr1.java (yy_table_value_is_error_): Likewise.
1814 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
1815 * src/tables.h: In header comments, explain why it's useless to
1816 check for a zero value in yytable.
1817
1818 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
1819
1820 More fixes related to last two patches.
1821 * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
1822 comments: zero indicates syntax error not default action.
1823 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
1824 defined.
1825 * data/glr.c (yyis_pact_ninf): Rename to...
1826 (yypact_value_is_default): ... this.
1827 (yyisDefaultedState): Update for rename.
1828 (yyis_table_ninf): Rename to...
1829 (yytable_value_is_error): ... this, and check for value zero
1830 besides just YYTABLE_NINF.
1831 (yygetLRActions): Check for default value from yypact. It
1832 appears that this check is always performed before this function
1833 is invoked, and so adding the check here is probably redundant.
1834 However, the code may evolve after this subtlety is forgotten.
1835 Also, update for rename to yytable_value_is_error. Because that
1836 macro now checks for zero, a different but equivalent branch of
1837 the if-then-else here is evaluated.
1838 (yyreportSyntaxError): Update for rename to
1839 yytable_value_is_error. The zero condition was mishandled
1840 before.
1841 (yyrecoverSyntaxError): Update for renames. No behavioral
1842 changes.
1843 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
1844 New function.
1845 (yy_table_value_is_error_): New function.
1846 (parse): Use new functions where possible. No behavioral
1847 changes.
1848 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
1849 The zero condition was mishandled before.
1850 * data/yacc.c (yyis_pact_ninf): Rename to...
1851 (yypact_value_is_default): ... this.
1852 (yyis_table_ninf): Rename to...
1853 (yytable_value_is_error): ... this, and check for value zero
1854 besides just YYTABLE_NINF.
1855 (yysyntax_error): Update for rename to yytable_value_is_error.
1856 The zero condition was mishandled before.
1857 (yyparse): Update for renames. No behavioral changes.
1858 * src/tables.h: Improve comments about yypact, yytable, etc.
1859 more. Most importantly, say yytable value of zero means syntax
1860 error not default action.

1887 * data/lalr1.cc (yysyntax_error_): Likewise.

1894 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
1895 quote rather than implementing quoting here.

1899 Make previous patch more robust.
1900 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
1901 argmatch.h.
1902 (output_skeleton): Use it.
1903 Suggested by Akim Demaille.
1904
1905 Import latest m4/m4.m4.
1906 * submodules/autoconf: Update to autoconf 2.64.
1907 * configure.ac (M4_GNU_OPTION): New define.
1908 * src/output.c (output_skeleton): Use it to resolve FIXME.
1909 * NEWS: Mention this.

1913 Fix complaints about escape sequences.
1914 Discussed starting at
1915 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
1916 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
1917 For a \0 and similar escape sequences meaning the null
1918 character, report an invalid escape sequence instead of an
1919 invalid null character because the latter does not actually
1920 appear in the user's input.
1921 In all escape sequence complaints, don't escape the initial
1922 backslash, and don't quote when the sequence appears at the end
1923 of the complaint line unless there's whitespace that quotearg
1924 won't escape.
1925 Consistently say "invalid" not "unrecognized".
1926 Consistently prefer "empty character literal" over "extra
1927 characters in character literal" warning for invalid escape
1928 sequences; that is, consistently discard those sequences.
1929 * tests/input.at (Bad escapes in literals): New.

1954 Remove variable_tr, no longer needed.
1955 * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
1956 Remove.
1957 * data/c++.m4: No longer handle namespace -> api.namespace.

1973 Move argument names into yy*.
1974
1975 2009-08-19 Akim Demaille <demaille@gostai.com>
1976
1977 lalr1.cc: get rid of yyparse's yystate.
1978 yystate and yystack_[0].state are equal, keep only the latter.
1979 The former was also used as a temporary variable to compute the
1980 post-reduction state. Move this computation into an auxiliary
1981 function.
1982
1983 * data/glr.c (yyLRgotoState): Fuse variable definition and first
1984 assignment.
1985 * data/lalr1.cc (yy_lr_goto_state_): New.
1986 (yyparse): Use it.
1987 Replace remaining uses of yystate by yystate_[0].state.

1989
1990 2009-08-19 Akim Demaille <demaille@gostai.com>
1991
1992 lalr1.cc: destroy $$ when YYERROR is called.
1993 * data/lalr1.cc (yyreduce): Compute the resulting state before
1994 running the user action so that yylhs is a valid symbol.
1995 (yyerrorlab): Since yylhs is complete (it knows its type), we can
1996 simply call yy_destroy_ to destroy $$ on YYERROR invocations.
1997 * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.

2019 build: lower gettext requirements.
2020
2021 Bison was uselessly requiring the formatstring macros from
2022 gettext, which resulted in mo files not being installed on systems
2023 that perfectly supported Bison mo files. Lower the requirement.
2024 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html

2052 (symbols_free): Free symbols_sorted.
2053 (symbols_cmp, symbols_cmp_qsort): New functions.
2054 (symbols_do): Sort symbol_table into symbols_sorted on first

2056 * tests/input.at (Numbered tokens): Recombine tests now that the
2057 output should be deterministic across multiple numbers.

2066
2067 build: fix the generation of the documentation.
2068 Some of our targets use "bison --help", but they can't depend on
2069 "bison" itself (to avoid additional requirements on the user), so
2070 they used to call "make src/bison" in the commands. Then
2071 concurrent builds may fail: one make might be aiming one of its
2072 jobs at compiling src/bison, and another job at generating the man
2073 page. If the latter is faster than the former, then we have two
2074 makes that concurrently try to compile src/bison.
2075
2076 This might also be a more convincing explanation for the failure
2077 described in the patch "build: fix paths".
2078
2079 * Makefile.am (SUFFIXES): Initialize.
2080 * build-aux/move-if-change: New, symlink to gnulib's.
2081 * build-aux/local.mk: Ship it.

2086 Use src/bison.
2087 (.x.1): Replace with...
2088 (doc/bison.1): this explicit, simpler, target.
2089 (common_dep): Remove, inlined where appropriate.
2090 (SUFFIXES, PREPATH): Remove, unused.

2098 Adjust more variables.
2099 * etc/prefix-gnulib-mk (prefix_assignment): Don't rename

2108 build: fix paths.
2109 When using $(top_builddir) inconsistently, Make (including GNU
2110 Make) is sometimes confused. As a result it may want to build
2111 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
2112 file, different names) concurrently, which, amusingly enough,
2113 might end with:
2114
2115 ranlib lib/libbison.a
2116 ranlib lib/libbison.a
2117 make[2]: *** [lib/libbison.a] Segmentation fault
2118
2119 on OS X.
2120

2122 needed.

2134 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
2135
2136 Miscellaneous code readability improvements.
2137
2138 * src/reader.c (reader): Move %define front-end variable
2139 defaults and checking into...
2140 (prepare_percent_define_front_end_variables): ... this new
2141 function.
2142
2143 * src/scan-gram.l (INITIAL): For consistency with string
2144 literals, don't store open quote on character literal. It's
2145 discarded before returning anyway.
2146 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
2147 Make length test more readable, and make the character stored
2148 for an empty literal more obvious while consistent with the
2149 previous behavior.
2150
2151 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
2152 USER_NUMBER_HAS_STRING_ALIAS throughout.
2153 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
2154 that is repeated in symtab.h. Improve argument names to make it
2155 clear which side of the symbol-string alias pair is which.
2156 (symbol_check_alias_consistency): Improve local variable names
2157 for the same purpose.
2158 * src/symtab.h (struct symbol): Make comments about aliases
2159 clearer.
2160 (symbol_make_alias): Improve comments and argument name.
2161 * src/output.c (token_definitions_output): Update for rename to
2162 USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
2163
2164 2009-08-08 Alex Rozenman <rozenman@gmail.com>
2165
2166 Convert "misleading reference" messages to warnings.

2232 * src/scan-code.l: Add "%option noinput", which I cannot find in
2233 the Flex manual, but which Flex has supported since at least as
2234 far back as 2.5.4. However, if any of our developers still use
2235 Flex 2.5.4, they'll need to stop configuring with
2236 --enable-gcc-warnings because "%option noinput" didn't work
2237 correctly until Flex 2.5.6.
2238 * src/scan-gram.l: Likewise.
2239 * src/scan-skel.l: Likewise.
2240
2241 2009-07-31 Alex Rozenman <rozenman@gmail.com>
2242
2243 Fix --enable-gcc-warnings problems.
2244 * src/reader.c: Adjust variable names.
2245 * src/scan-code.l: Fix prototypes and adjust names.
2246 * src/named-ref.c: Remove redundant "if".

2248 2009-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
2249
2250 Fix a --enable-gcc-warnings problem.
2251 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
2252 variable.
2253
2254 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
2255
2256 Warn about character literals not of length one.
2257 * NEWS (2.5): Document.
2258 * src/scan-gram.l (INITIAL): Remove comment that we don't check
2259 the length.
2260 (SC_ESCAPED_CHARACTER): Warn if length is wrong.
2261 * tests/input.at (Bad character literals): New test group.
2262
2263 2009-07-24 Alex Rozenman <rozenman@gmail.com>
2264
2265 Fix some memory leaks.
2266 * src/named-ref.c: Add a pointer check (named_ref_free).
2267 * src/scan-code.l: New function (variant_table_free). Called in
2268 code_scanner_free.
2269 * src/symlist.c: Call to named_ref_free (symbol_list_free).

2276
2277 Some M4 cleanup in the testsuite.
2278 Suggested by Eric Blake at
2279 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
2280 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
2281 complicate the code by distinguishing between a missing value
2282 and an empty string value for an optional argument. This fix is
2283 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
2284 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
2285 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
2286 arguments are not needed because of the following changes.
2287 Fix stale comments.
2288 Bison developers should use GNU M4 and should not use
2289 POSIXLY_CORRECT when building the test suite, so do not
2290 complicate the code by avoiding $10 and above.
2291 Do not quote an empty string value for an optional argument, and
2292 do not distinguish between a missing value and an empty string
2293 value.

2302 2009-07-04 Alex Rozenman <rozenman@gmail.com>
2303
2304 Alphabetical order in src/local.mk.

2306
2307 2009-07-04 Alex Rozenman <rozenman@gmail.com>
2308
2309 Style changes and factoring.

2312 * src/reader.c: Factoring: assign_named_ref function.
2313 * src/scan-code.l: Factoring and style changes. Rename
2314 parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.

2325
2326 2009-06-29 Akim Demaille <demaille@gostai.com>
2327
2328 build: avoid concurrent extraction of calc++.
2329 * examples/calc++/Makefile.am (calc.stamp): New.
2330 Depend on it to create the sources of calc++ so that concurrent
2331 builds don't launch several "extexi" in parallel.
2332 Not only this is inefficient, this also builds incorrect sources
2333 with several extractions mixed together.
2334
2335 2009-06-29 Akim Demaille <demaille@gostai.com>
2336
2337 parse.error: fix.
2338 * data/bison.m4: Move code related to specific variables after the
2339 definition of the variable-maintaining macros so that we don't
2340 "invoke" b4_percent_define_check_values before it is defined.
2341
2342 2009-06-29 Akim Demaille <demaille@gostai.com>

2369 * src/reader.h: New argument for symbol_append and
2370 action_append functions.
2371 * src/scan-code.h: Add new field (named_ref) into
2372 code_props data structure. Keeps named ref of midrule
2373 actions.
2374 * src/scan-code.l: Support for named refs in semantic
2375 action code. New function 'parse_named_ref'.
2376 * src/scan-gram.l: Support bracketed id.

2381 * src/local.mk: Add two new files.
2382 * tests/testsuite.at: Include new test group:

2402 Default the latter to the former.
2403 * doc/bison.texinfo (Decl Summary): Document "namespace" as
2404 obsolete.
2405 Document api.namespace.
2406 Use @samp to document %define uses, keep @code for identifiers.
2407 * NEWS: Likewise.
2408 * tests/c++.at, tests/input.at: Test api.namespace instead of
2409 namespace. (The tests passed with namespace.)

2440
2441 deterministic test suite.
2442 Some consistency checks on symbols are performed after all the
2443 symbols were read, by an iteration over the symbol table. This
2444 traversal is nondeterministic, which can be a problem for test
2445 cases.
2446 Avoid this.
2447 Addresses another form of nondeterminism reported by Joel E. Denny.
2448 http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00023.html
2449

2501 --force-define with %define.
2502 * doc/bison.texinfo (Decl Summary): In %define entry,
2503 cross-reference command-line options.
2504 (Bison Options): Add documentation to -D/--define entry.
2505 (Option Cross Key): Widen column for --force-define row.
2506 * src/getargs.c (usage): Document -F/--force-define. Realign

2522
2523 Update some comments to make sense for -D.
2524 * data/bison.m4 (b4_check_user_names): In header comments, say
2525 "user occurrence" instead of "grammar occurrence".

2527 (muscle_percent_code_grow): Likewise just for consistency.
2528
2529 2009-05-20 Joel E. Denny <jdenny@ces.clemson.edu>

2533 2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>
2534
2535 Handle a trailing `:' in a user-supplied C++ namespace better.
2536 * data/c++.m4 (b4_namespace_close): Don't let it be printed
2537 among the closing braces here. This fix might make the
2538 generated code easier to debug, but otherwise it should be
2539 insignificant because a trailing `:' is a C++ error already.
2540
2541 2009-05-19 Akim Demaille <demaille@gostai.com>
2542
2543 remove useless variable.
2544 * src/getargs.c (skeleton_arg): Remove now useless variable.

2612 * src/files.c (tr): Move to...
2613 * src/getargs.c, src/getargs.h (tr): ... here because I can't
2614 think of a better place to expose it. My logic is that, for all
2615 uses of tr so far, command-line arguments can be involved, and
2616 getargs.h is already included.
2617 * src/main.c (main): Update access.

2720 restrictions.
2721 (GLR parsing): Say deterministic or LR(1) rather than LALR(1)
2722 when trying to distinguish from GLR. Talk about LR(1) grammars
2723 rather than LALR(1) grammars.
2724 (Decl Summary): In %define api.push_pull entry, say it applies
2725 to deterministic parsers in C rather than LALR(1) parsers in C.

2823 lr.default_rules is "accepting".
2824 * src/tables.c (action_row): If lr.default_rules is not "all",
2825 then disable default rules in inconsistent states.
2826 * src/print.c (print_reductions): Use this opportunity to

3004 Replace BISON_PROG_GNU_M4 with Autoconf's AC_PROG_GNU_M4.
3005 If the first m4 in $PATH is wrong, it keeps looking. Moreover, its

3048 Treat %error-verbose as %define error_verbose.
3049 This allows to pass -Derror_verbose on the command line. Better
3050 yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
3051 ERROR_VERBOSE being defined as false or true.
3052 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
3053 on b4_percent_define_ifdef, for does not check the defined value,
3054 but only whether the symbol is defined, rely on
3055 b4_percent_define_flag_if, so that a value of "false" is processed
3056 as a false.
3057 If not defined, define the flag to "false".
3058 (b4_error_verbose_if): New.
3059 * data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of

3070 and discussed again starting at
3071 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
3072 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
3073 because location information is bogus.
3074 Use angle brackets to delimit fake file name because square brackets
3075 look like underexpanded m4. Choose a better fake file name.
3076 Use negative line numbers.
3077 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
3078 * src/location.c (location_print): If line for a boundary is negative,
3079 only print that boundary's file name.

3119 lalr1.cc: avoid GCC 4.3 warnings.
3120 GCC 4.3 now warns about "a || b && c" and asks for explicit
3121 parentheses.
3122 Reported by Alexandre Duret-Lutz.
3123 * data/location.cc: Update copyright years.
3124 (Position::operator==): Use parens to make precedence explicit.
3125 Compare lines and columns first, as they are more likely to be
3126 different, and they are faster to compare.

3149 Use locations in the variant example.
3150 Yes, this obfuscates the point of this example, variants only.
3151 But glr.cc cannot work (yet?) without locations. This change
3152 makes it easier to use this example with glr.cc.
3153
3154 * examples/variant.yy (assert): %define it.
3155 (locations): Request them.
3156 (yylex): Bind the location to the stage.

3169 Remove the "b4_variant_if" parts, as variant.hh is loaded only if
3170 needed.
3171 * data/lalr1.cc: No longer invoke b4_symbol_constructor_define and
3172 b4_symbol_constructor_declare, as it is now done by
3173 b4_public_types_define and b4_public_types_declare.

3267 Make yyparser::error public.
3268 * data/lalr1.cc: here.
3269 There is no good reason to keep it private (and it is convenient
3270 to use it from the scanner for instance). It is already public in
3271 glr.cc.

3356
3357 Propagate i18n changes into glr.c.

3379
3380 Fix portability issue in the test suite.
3381 * tests/local.at (AT_MATCHES_CHECK): New.
3382 Based on Perl instead of Sed. Sed has too many portability
3383 pitfalls, not ever Sed is GNU Sed.
3384 * tests/actions.at (Fix user actions without a trailing semicolon):
3385 Use it.
3386
3387 2008-12-08 Akim Demaille <demaille@gostai.com>

3411
3412 Fix regeneration of atconfig.
3413 * tests/local.mk (tests/atconfig): The rule was incorrect, but
3414 remove it: now that there is no tests/Makefile.am, the top-level
3415 Makefile properly updates atconfig when needed.
3416
3417 2008-12-07 Di-an Jan <dianj@freeshell.org>
3418
3419 Implement the FIXME that ends an user action with a semicolon
3420 if it seems necessary.
3421 * src/scan-code.l (flex rules section): Flag cpp directive from
3422 any `#' to the first unescaped end-of-line. Semicolon is not
3423 needed after `;', `{', '}', or cpp directives and is needed after
3424 any other token (whitespaces and comments have no effect).
3425 * tests/actions.at (Fix user actions without a trailing semicolon):
3426 New test.
3427 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
3428 to make user actions complete statements.
3429 Adjust column numbers in error messages.
3430 * tests/regression.at (Fix user actions without a trailing semicolon):
3431 Remove. Covered by new test.

3442 function.
3443
3444 2008-12-02 Eric Blake <ebb9@byu.net>
3445
3446 Build testsuite with newer autoconf.
3447 * tests/output.at (m4_expand): Don't override in newer autoconf,
3448 where the underlying implementation changed.
3449 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
3450 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
3451 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
3452 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
3453 since some of them contain unbalanced ')'.
3454
3455 2008-12-01 Akim Demaille <demaille@gostai.com>
3456
3457 Use b4_symbol for printers and destructors everywhere.
3458 * data/bison.m4 (b4_symbol_action_location): New.
3459 * data/c.m4 (b4_symbol_actions): Remove.
3460 Adjust all callers to use by b4_symbol_foreach and the corresponding
3461 b4_symbol_printer/destructor macro.
3462 * data/glr.cc: Adjust.
3463 * data/lalr1.java: Adjust the %destructor sanity check.
3464 * src/output.c (symbol_code_props_output): Remove, we no longer
3465 need the b4_symbol_printers/destructors tables.
3466
3467 2008-12-01 Akim Demaille <demaille@gostai.com>
3468
3469 Use b4_symbol_case_.
3470 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
3471 b4_symbol_case_.
3472
3473 2008-12-01 Akim Demaille <demaille@gostai.com>
3474
3475 Move b4_symbol based macro to bison.m4.
3476 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
3477 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
3478 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
3479 (b4_type_foreach): Move to...
3480 * data/bison.m4: Here.
3481 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
3482 b4_symbol_value_template instead of b4_symbol_value.
3483
3484 2008-12-01 Akim Demaille <demaille@gostai.com>
3485
3486 b4_symbol/type_foreach.
3487 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
3488 Use them.
3489
3490 2008-12-01 Akim Demaille <demaille@gostai.com>
3491
3492 Use the symbol properties to output the printer/destructor for lalr1.cc.
3493 Instead of defining complex list of tuples to define various
3494 properties of the symbols, we now prefer to define symbols as
3495 "structs" in m4: using the symbol key (its number), and the
3496 property name, b4_symbol gives it value. Use this to handle
3497 destructors and printers.
3498
3499 * src/output.c (CODE_PROP): New.
3500 (prepare_symbol_definitions): Use it to define the printer and
3501 destructor related attributes of the symbols.
3502 * data/lalr1.cc (b4_symbol_actions): Rename as...
3503 (b4_symbol_action): this.
3504 Use b4_symbol instead of 6 arguments.
3505 (b4_symbol_printer, b4_symbol_destructor): New.
3506 Use them instead of b4_symbol_actions.
3507
3508 2008-12-01 Akim Demaille <demaille@gostai.com>
3509
3510 Avoid capturing variables too easily.
3511 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
3512 v__ and p__ instead of v and p.
3513
3514 2008-12-01 Akim Demaille <demaille@gostai.com>
3515
3516 Remove spurious empty line before syncline.
3517 * data/bison.m4 (b4_syncline): Don't output an empty line before
3518 the output.
3519
3520 2008-11-26 Akim Demaille <demaille@gostai.com>
3521
3522 Convert lib/Makefile.am into lib/local.mk.
3523 The real problem is rather gnulib.mk, which itself is extracted
3524 from a Makefile.am that gnulib expects to the "recursive". The
3525 tool prefix-gnulib-mk converts such a gnulib.mk to be
3526 non-recursive. Also, some AC_SUBST variables need to be adjusted.
3527
3528 * etc/prefix-gnulib-mk: New.
3529 * bootstrap (slurp): Use it to convert further gnulib.mk.
3530 No longer try to avoid re-creation of lib/gnulib.mk as the changes
3531 are deeper.
3532 * lib/Makefile.am: Rename as...
3533 * lib/local.mk: this.
3534 Adjust to be prefixed.
3535 * Makefile.am, configure.ac: Adjust.
3536 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
3537
3538 2008-11-26 Akim Demaille <demaille@gostai.com>
3539
3540 s/_FLAGS/FLAGS/.
3541 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
3542 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
3543 Reported by Eric Blake.
3544
3545 2008-11-26 Akim Demaille <demaille@gostai.com>
3546
3547 Use b4_parser_tables_define in glr.cc.
3548 * data/glr.c: Use b4_parser_tables_define instead of defining the
3549 (deterministic integral) tables by hand.
3550
3551 2008-11-26 Akim Demaille <demaille@gostai.com>
3552
3553 Use b4_parser_tables_define in Java.
3554 * data/java.m4 (b4_typed_parser_table): Rename as...
3555 (b4_typed_parser_table_define): this, for consistency.
3556 Accept a comment as $4.
3557 Move $2 into yy*_.
3558 (b4_integral_parser_table): Rename as...
3559 (b4_integral_parser_table_define): this.

3564
3565 Prepare the convergence bw C style and Java table generation.
3566 * data/bison.m4 (b4_tables_map, b4_tables_declare)
3567 (b4_tables_define): Rename as...
3568 (b4_integral_parser_tables_map, b4_parser_tables_declare)

3590 Update the comment for yytable during the flight.
3591 (b4_tables_declare, b4_tables_define): New.
3592 * data/lalr1.cc: Use them.
3593 * data/c.m4 (b4_table_define): New.

3595 by hand.
3596 * tests/regression.at (Web2c Actions): Adjust the expected output,
3597 the order of the tables changed.
3598
3599 2008-11-26 Akim Demaille <demaille@gostai.com>
3600
3601 Get rid of (yy)rhs and (yy)prhs.
3602 These tables are no longer needed in the parsers, and they don't seem to
3603 be useful. They are not documented either.
3604
3605 * src/output.c (prepare_rules): Get rid of rhs and prhs.
3606 Adjust the computation of (yy)r2.
3607
3608 2008-11-26 Akim Demaille <demaille@gostai.com>
3609
3610 Rule length is unsigned.
3611 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
3612
3613 2008-11-26 Akim Demaille <demaille@gostai.com>
3614
3615 Get rid of lalr1-split.cc.
3616 It was no longer maintainer.
3617
3618 * data/lalr1-split.cc: Remove.
3619 * etc/bench.pl.in (bench_fusion_parser): Remove.
3620 Adjust.
3621
3622 2008-11-26 Akim Demaille <demaille@gostai.com>
3623
3624 Use yy* consistently.
3625 * data/glr.c: Now that yyrhs no longer exists as a global
3626 variable, rename local "rhs" variables into "yyrhs" for
3627 consistency.
3628
3629 2008-11-25 Akim Demaille <demaille@gostai.com>
3630
3631 Get rid of yyrhs and yyprhs in glr.c.
3632 * data/glr.c (yyrhs, yyprhs): Remove.
3633 Instead, use the state stack and yystos.
3634
3635 2008-11-25 Akim Demaille <demaille@gostai.com>
3636
3637 Flag glr tests.
3638 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
3639 as an Autotest keyword.
3640
3641 2008-11-25 Akim Demaille <demaille@gostai.com>
3642
3643 Prefer TESTSUITE_FLAGS.
3644 TESTSUITEFLAGS is barely readable.
3645
3646 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
3647 for backward compatibility.
3648 Use the former instead of the latter.
3649
3650 2008-11-25 Akim Demaille <demaille@gostai.com>
3651
3652 Get rid of yyrhs and yyprhs in larl1.java.
3653 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
3654 (yy_reduce_print): Rather, use yystos_ and the state stack.
3655
3656 2008-11-25 Akim Demaille <demaille@gostai.com>
3657
3658 Formatting changes.
3659
3660 2008-11-25 Akim Demaille <demaille@gostai.com>
3661
3662 Get rid of yyrhs and yyprhs in yacc.c.
3663 They were used to get the symbol types, given a rule number, when
3664 displaying the top of the stack before a reduction. But the
3665 symbol type is available from the state stack. This has two be
3666 benefits: two tables less in the parser (making it smaller), and a
3667 more consistent use of the three stacks which will help to fuse
3668 them.
3669
3670 * data/yacc.c (yyprhs, yyrhs): Remove.
3671 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
3672 (yy_reduce_print): Take yyssp as argument.
3673 Use it, together with yystos, to get the symbol type.
3674 * tests/regression.at (Web2c Report): Remove these tables from the
3675 expected output.
3676
3677 2008-11-25 Akim Demaille <demaille@gostai.com>
3678
3679 b4_tables_map.
3680 The point is to factor the generation of the tables across skeletons.
3681 This is language dependant.
3682
3683 * data/c.m4 (b4_comment_): New.
3684 Should be usable to define how to generate tables independently of
3685 the language.
3686 (b4_c_comment): New.
3687 (b4_comment): Bounce to b4_c_comment.
3688 Now support $2 = [PREFIX] for indentation.
3689 * data/lalr1.cc (b4_table_declare): Don't output a comment if
3690 there is no comment.
3691 Indent it properly when there is one.
3692 Output the ending semicolon.
3693 (b4_table_define): Space changes.
3694 Output the ending semicolon.
3695 (b4_tables_map): New.
3696 Use it twice instead of declaring and defining the (integral)
3697 tables by hand.
3698
3699 2008-11-25 Akim Demaille <demaille@gostai.com>
3700
3701 b4_table_declare.
3702 * data/lalr1.cc (b4_table_declare): New.
3703 Use it to declare the tables defined with b4_table_define.
3704 (b4_table_define): Declare a third arg to match b4_table_declare
3705 signature.
3706 Move all the comments around invocations of b4_table_define into
3707 the invocations itselves.
3708 Move things around to have the order for declarations and
3709 definitions.

3743 src/scan-gram.l (actual name passed as the first argument)
3744 with special case for %define.
3745 * doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l
3746 to build-aux/cross-options.pl.

3863 Support parametric types.
3864
3865 There are two issues to handle: first scanning nested angle
3866 bracket pairs to support types such as std::pair< std::string,
3867 std::list<std::string> > >.
3868
3869 Another issue is to address idiosyncracies of C++: do not glue two
3870 closing angle brackets together (otherwise it's operator>>), and
3871 avoid sticking blindly a TYPE to the opening <, as it can result
3872 in '<:' which is a digraph for '['.

3890 Test token.prefix.
3891 This is not sufficient, but we test at least that the make_SYMBOL
3892 interface is not affected by token.prefix. A more general test
3893 will be implemented when the support of token.prefix is generalized
3894 to more skeletons.
3895

3971 It does not work, and I don't know how it was supposed to work: it

4030 Remove examples/local.mk.
4031 examples/calc++/Makefile.am might be interesting to keep as is, since
4032 it is an example in itself.

4051
4052 Provide convenience constructors for locations and positions.
4053 * data/location.cc (position::position): Accept file, line and
4054 column as arguments with default values.
4055 Always qualify initial line and column literals as unsigned.
4056 (location::location): Provide convenience constructors.
4057
4058 2008-11-15 Akim Demaille <demaille@gostai.com>
4059
4060 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
4061 token type.
4062 Using template buys us nothing, and makes it uselessly complex to
4063 construct a symbol. Besides, it could not be generalized to other
4064 languages, while make_FOO would work in C/Java etc.
4065
4066 * data/lalr1.cc (b4_symbol_): New.
4067 (b4_symbol): Use it.
4068 (b4_symbol_constructor_declaration_)
4069 (b4_symbol_constructor_definition_): Instead of generating
4070 specializations of an overloaded template function, just generate
4071 several functions whose names are forged from the token names
4072 without the token.prefix.
4073 (b4_symbol_constructor_declarations): Generate them for all the
4074 symbols, not just by class of symbol type, now that instead of
4075 specializing a function template by the token, we generate a
4076 function named after the token.
4077 (b4_symbol_constructor_specialization_)
4078 (b4_symbol_constructor_specializations): Remove.
4079 * etc/bench.pl.in: Adjust to this new API.
4080
4081 2008-11-13 Akim Demaille <demaille@gostai.com>
4082
4083 %define token.prefix.
4084 Provide a means to add a prefix to the name of the tokens as
4085 output in the generated files. Because of name clashes, it is
4086 good to have such a prefix such as TOK_ that protects from names
4087 such as EOF, FILE etc. But it clutters the grammar itself.
4088
4089 * data/bison.m4 (token.prefix): Empty by default.
4090 * data/c.m4 (b4_token_enum, b4_token_define): Use it.

4101 symbol::token.
4102 This allows the user to get the type of a token returned by yylex.
4103
4104 * data/lalr1.cc (symbol::token): New.
4105 (yytoknum_): Define when %define lex_symbol, independently of
4106 %debug.
4107 (yytoken_number_): Move into...
4108 (symbol::token): here, since that's the only use.
4109 The other one is YYPRINT which was not officially supported
4110 by lalr1.cc, and anyway it did not work since YYPRINT uses this
4111 array under a different name (yytoknum).

4124
4125 Comment changes.
4126 * data/lalr1.cc, data/yacc.c: Fix the description of the
4127 yytranslate and yytoknum tables.
4128
4129 2008-11-13 Akim Demaille <demaille@gostai.com>
4130
4131 Define make_symbol in the header.
4132 To reach good performances these functions should be inlined (yet
4133 this is to measure precisely). To this end they must be available
4134 to the caller.
4135
4136 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
4137 location_type with the class name.
4138 Since will now be output in the header, declare "inline".
4139 No longer use b4_symbol_constructor_specializations, but
4140 b4_symbol_constructor_definitions in the header.
4141 Don't call it in the *.cc file.
4142
4143 2008-11-13 Akim Demaille <demaille@gostai.com>
4144
4145 Define yytranslate in the header for lex_symbol.
4146 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
4147 into the header file when using %define lex_symbol.
4148 (yytranslate_): Declare inline.
4149
4150 2008-11-13 Akim Demaille <demaille@gostai.com>
4151
4152 Define the constructors of symbol_type in
4153 b4_symbol_constructor_definitions.
4154 The constructors are called by the make_symbol functions, which a
4155 forthcoming patch will move elsewhere. Hence the interest of
4156 putting them together.
4157
4158 The stack_symbol_type does not need to be moved, it is used only
4159 by the parser.
4160
4161 * data/lalr1.cc: Move symbol_type and symbol_base_type
4162 constructors into...
4163 (b4_symbol_constructor_definitions): here.
4164 Adjust.
4165
4166 2008-11-13 Akim Demaille <demaille@gostai.com>
4167
4168 Make it easier to move the definition of yytranslate_.
4169 Forthcoming changes will make it possible to use yytranslate_
4170 from outside the parser implementation file.
4171
4172 * data/lalr1.cc (b4_yytranslate_definition): New.
4173 Use it.
4174
4175 2008-11-13 Akim Demaille <demaille@gostai.com>
4176
4177 Remove useless class specification.
4178 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
4179 to refer to the class name to use a type defined by the class for
4180 arguments of member functions.
4181
4182 2008-11-13 Akim Demaille <demaille@gostai.com>
4183
4184 Finer input type for yytranslate.
4185 This patch is debatable: the tradition expects yylex to return an int
4186 which happens to correspond to token_number (which is an enum). This
4187 allows for instance to return characters (such as '*' etc.). But this
4188 goes against the stronger typing I am trying to have with the new
4189 lex interface which return a symbol_type. So in this case, feed
4190 yytranslate_ with a token_type.
4191
4192 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
4193 expect a token_type.
4194
4195 2008-11-13 Akim Demaille <demaille@gostai.com>
4196
4197 Honor lex-params in %define lex_symbol mode.
4198 * data/lalr1.cc: Use b4_lex_param.
4199
4200 2008-11-13 Akim Demaille <demaille@gostai.com>
4201
4202 Simplify names.
4203 * src/output.c (symbol_definitions_output): Rename symbol
4204 attributes type_name and has_type_name as type and has_type.
4205 * data/lalr1.cc: Adjust uses.
4206
4207 2008-11-13 Akim Demaille <demaille@gostai.com>
4208
4209 Use b4_type_names for the union type.
4210 The union used to compute the size of the variant used to iterate
4211 over the type of all the symbols, with a lot of redundancy. Now
4212 iterate over the lists of symbols having the same type-name.
4213
4214 * data/lalr1.cc (b4_char_sizeof_): New.
4215 (b4_char_sizeof): Use it.
4216 Adjust to be called with a list of numbers instead of a single
4217 number.
4218 Adjust its caller for new-line issues.
4219
4220 2008-11-13 Akim Demaille <demaille@gostai.com>
4221
4222 Define the "identifier" of a symbol.
4223 Symbols may have several string representations, for instance if
4224 they have an alias. What I call its "id" is a string that can be
4225 used as an identifier. May not exist.
4226
4227 Currently the symbols which have the "tag_is_id" flag set are
4228 those that don't have an alias. Look harder for the id.
4229
4230 * src/output.c (is_identifier): Move to...
4231 * src/symtab.c (is_identifier): here.
4232 * src/symtab.h, src/symtab.c (symbol_id_get): New.
4233 * src/output.c (symbol_definitions_output): Use it to define "id"
4234 and "has_id".
4235 Remove the definition of "tag_is_id".
4236 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
4237 "tag_is_id" were used to produce code.
4238 We still use "tag" for documentation.
4239

4245 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
4246 (AT_CHECK_NAMESPACE): Check the use of locations.
4247 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
4248 without locations with lalr1.cc.
4249 Test these cases.
4250 * tests/output.at: Check lalr1.cc with and without location
4251 support.
4252 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
4253 Don't use locations.

4366
4367 Introduce make_symbol.
4368 make_symbol provides a means to construct a full symbol (kind,
4369 value, location) in a single shot. It is meant to be a Symbol
4370 constructor, parameterized by the symbol kind so that overloading
4371 would prevent incorrect kind/value pairs. Unfortunately
4372 parameterized constructors do not work well in C++ (unless the
4373 parameter also appears as an argument, which is not acceptable),
4374 hence the use of a function instead of a constructor.
4375
4376 * data/lalr1.cc (b4_symbol_constructor_declaration_)

4382 Use them where appropriate to generate declaration, declaration of
4383 the specializations, and implementations of the templated
4384 overloaded function "make_symbol".
4385 (variant::variant): Always define a default ctor.
4386 Also provide a copy ctor.
4387 (symbol_base_type, symbol_type): New ctor overloads for value-less
4388 symbols.
4389 (symbol_type): Now public, so that functions such as yylex can use
4390 it.

4401 Test 214 was failing: it greps with a pattern containing [ ]*
4402 which obviously meant to catch spaces and tabs, but contained only
4403 spaces. Tabulations in sources are a nuisance, so to simplify the
4404 matter, get rid of all the tabulations in the Java sources. The
4405 other skeletons will be treated equally later.
4406
4407 * data/java.m4, data/lalr1.java: Untabify.

4446 the other skeletons.
4447 (b4_user_post_prologue): Add. Don't silently drop.

4526 Make parser::yytranslate static.
4527 Small speedup (1%) on the list grammar. And makes yytranslate_
4528 available in non member functions.
4529
4530 * data/lalr1.cc (yytranslate_): Does not need to be a instance
4531 function.

4534
4535 Avoid trailing spaces.
4536 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
4537 * data/lalr1.cc: Don't indent before rule and symbol actions, as
4538 they can be empty, and anyway this incorrectly indents the first
4539 action.

4551 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.

4588
4589 Change the handling of the symbols in the skeletons.
4590 Before we were using tables which lines were the symbols and which
4591 columns were things like number, tag, type-name etc. It is was
4592 difficult to extend: each time a column was added, all the numbers had
4593 to be updated (you asked for colon $2, not for "tag"). Also, it was
4594 hard to filter these tables when only a subset of the symbols (say the
4595 tokens, or the nterms, or the tokens that have and external number
4596 *and* a type-name) was of interest.
4597
4598 Now instead of monolithic tables, we define one macro per cell. For
4599 instance "b4_symbol(0, tag)" is a macro name which contents is
4600 self-decriptive. The macro "b4_symbol" provides easier access to
4601 these cells.
4602
4603 * src/output.c (type_names_output): Remove.
4604 (symbol_numbers_output, symbol_definitions_output): New.
4605 (muscles_output): Call them.
4606 (prepare_symbols): Define b4_symbols_number.

4647 2008-11-10 Akim Demaille <demaille@gostai.com>
4648
4649 Add %precedence support.
4650 Unfortunately it is not possible to reuse the %prec directive. This
4651 is because to please POSIX, we do not require to end the rules with a
4652 semicolon. As a result,
4653
4654 foo: bar %prec baz
4655
4656 is ambiguous: either a rule which precedence is that of baz, or a rule,
4657 and then a declaration of the precedence of the token baz.
4658
4659 * doc/bison.texinfo: Document %precedence.
4660 (Precedence Only): New.
4661 * src/assoc.h, src/assoc.c (precedence_assoc): New.

4788 To display rhs symbols before a reduction, we used information

4904 Handle more general types of option arguments.
4905 * build-aux/cross-options.pl: The argument ends at the first
4906 space, not the first non-symbol character.
4907 Use @var for each word appearing the argument description.

4915 (yyreduce): Invoke yydestruct_ when popping lhs symbols.
4916
4917 2008-11-07 Akim Demaille <demaille@gostai.com>
4918
4919 Add "%define assert" to variants.
4920 This is used to help the user catch cases where some value gets
4921 ovewritten by a new one. This should not happen, as this will
4922 probably leak.
4923
4924 Unfortunately this uncovered a bug in the C++ parser itself: the
4925 lookahead value was not destroyed between two calls to yylex. For
4926 instance if the previous lookahead was a std::string, and then an int,
4927 then the value of the std::string was correctly taken (i.e., the
4928 lookahead was now an empty string), but std::string structure itself
4929 was not reclaimed.
4930
4931 This is now done in variant::build(other&) (which is used to take the
4932 value of the lookahead): other is not only stolen from its value, it
4933 is also destroyed. This incurs a new performance penalty of a few
4934 percent, and union becomes faster again.
4935
4936 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
4937 (b4_variant_if): New.
4938 (variant::built): New.
4939 Use it whereever the status of the variant changes.
4940 * etc/bench.pl.in: Check the penalty of %define assert.
4941
4942 2008-11-07 Akim Demaille <demaille@gostai.com>
4943
4944 Use "%define variant" in bench.pl.
4945 * etc/bench.pl.in: No longer use the pseudo directive %variants,
4946 just use %define variants.

5214
5215 Fuse the three stacks into a single one.
5216
5217 In order to make it easy to perform benchmarks to ensure that
5218 there are no performance loss, lalr1.cc is forked into
5219 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
5220 lalr1.cc.
5221
5222 Meanwhile, to make sure that lalr1-fusion.cc is correctly
5223 exercized by the test suite, the user must install a symbolic link
5224 from lalr1.cc to it.
5225
5226 Instead of having three stacks (state, value, location), use a
5227 stack of triples. This considerably simplifies the code (and it
5228 will be easier not to require locations as currently does the C++
5229 parser), and also gives a 10% speedup according to
5230 etc/bench (probably mainly since memory allocation is done once
5231 instead of three times).
5232
5233 Another motivation is to make it easier to destruct properly
5234 semantic values: now that they are bound to their state (hence
5235 symbol type) it will be easier to call the appropriate destructor.
5236
5237 These changes should probably benefit the C parser too.
5238
5239 * data/lalr1.cc: Copy as...
5240 * data/lalr1-fusion.cc: this new file.
5241 (b4_rhs_value, b4_rhs_location): New definitions overriding those
5242 from c++.m4.
5243 (state_stack_type, semantic_stack_type, location_stack_type)
5244 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
5245 (data_type, stack_type, yystack_): New.
5246 (YYLLOC_DEFAULT, yypush_): Adjust.
5247 (yyerror_range): Now based on data_type, not location_type.
5248
5249 2008-11-03 Akim Demaille <demaille@gostai.com>
5250
5251 Push the state, value, and location at the same time.
5252 This is needed to prepare a forthcoming patch that fuses the three
5253 stacks into one.
5254
5255 * data/lalr1.cc (parser::yypush_): New.
5256 (parser::yynewstate): Change the semantics: instead of arriving to
5257 this label when value and location have been pushed, but yystate
5258 is to be pushed on the state stack, now the three of them must
5259 have been pushed before. yystate still must be the new state.
5260 This allows to use yypush_ everywhere instead of individual
5261 handling of the stacks.
5262
5263 2008-11-03 Akim Demaille <demaille@gostai.com>
5264
5265 Prefer references to pointers.
5266 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
5267 definition to use references instead of pointers.
5268 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
5269 Take the value and location as references.
5270 Adjust callers.
5271
5272 2008-11-03 Akim Demaille <demaille@gostai.com>
5273
5274 stack::size instead of stack::height.
5275 * data/lalr1.cc (stack::height): Rename as...
5276 (stack::size): this.
5277 Fix the output type.
5278 Comment changes.

5281
5282 Use variants to support objects as semantic values.
5283 This patch was inspired by work by Michiel De Wilde. But he used
5284 Boost variants which (i) requires Boost on the user side, (ii) is
5285 slow, and (iii) has useless overhead (the parser knows the type of
5286 the semantic value there is no reason to duplicate this
5287 information as Boost.Variants do).
5288
5289 This implementation reserves a buffer large enough to store the
5290 largest objects. yy::variant implements this buffer. It was
5291 implemented with Quentin Hocquet.
5292
5293 * src/output.c (type_names_output): New.
5294 (output_skeleton): Invoke it.
5295 * data/c++.m4 (b4_variant_if): New.
5296 (b4_symbol_value): If needed, provide a definition for variants.
5297 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
5298 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
5299 (b4_char_sizeof, yy::variant): New.
5300 (parser::parse): If variants are requested, define
5301 parser::union_type, parser::variant, change the definition of
5302 semantic_type, construct $$ before running the user action instead
5303 of performing a default $$ = $1.
5304 * examples/variant.yy: New.
5305 Based on an example by Michiel De Wilde.
5306
5307 2008-11-03 Akim Demaille <demaille@gostai.com>
5308
5309 Parameterize the extraction of semantic values.
5310 To make future changes easier, no longer rely on ".TYPE" being the
5311 way to get a semantic value.
5312
5313 * data/c.m4 (b4_symbol_value): New.
5314 Use it.
5315 * data/c++.m4, data/yacc.c: Use it.
5316 * data/glr.c: Use b4_symbol_value.
5317 (b4_rhs_data): New.
5318 Use it.
5319
5320 2008-11-03 Akim Demaille <demaille@gostai.com>
5321
5322 Prepare easier M4 changes.
5323 * data/lalr1.cc: Use escaped [] instead of literals to prepare
5324 future changes.

5424 Always put auxiliary code files in the same dir as other output files.
5425 * src/files.c (compute_file_name_parts): When the user specifies
5426 --output but not --file-prefix, extract the directory prefix from the
5427 file prefix not from the grammar file name. This affects the location
5428 of files like location.hh generated by the C++ skeleton. The includes
5429 in the other output files require this fix.
5430 * tests/output.at (AT_CHECK_OUTPUT): Automatically create directories
5431 for expected output files.
5432 (Output files): Add a test for the above.

5503 * Makefile.cfg: Remove, and migrate settings to...
5504 * cfg.mk: ... here for the sake of `make announcement'.
5505 * bootstrap.conf (gnulib_modules): Add announce-gen.
5506 * README: Say GNU Bison instead of just Bison. Suggested by Karl
5507 Berry.
5508

5664
5665 Fix dependence on computed configure variables.
5666 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

5692 .prev-version, and .version.
5693 * NEWS (2.3b+): Rename to...
5694 (?.?): ... this because we're dropping the "+" version naming scheme,
5695 but, in general, we still can't be sure of our next release name.
5696 * bootstrap: Add a quick hack to remove from .gitignore the
5697 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
5698 entry. This should really be fixed in gnulib instead.

5700 * configure.ac (AC_INIT): Set version name by invoking

5732 * bootstrap (insert_sorted_if_absent): Replace all uses with...

5734 .gitignore entries before passing them to insert_sorted_if_absent.
5735 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
5736 .cvsignore files are maintained even though Bison developers run
5737 bootstrap while using Git.
5738 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
5739 unneeded by Bison.
5740 (gnulib): Add.
5741 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
5742 unneeded. Reported by Eric Blake.
5743 * lib/.gitignore (/*~): Add.
5744 * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
5745 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric

5754 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
5755 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
5756 (/setenv.m4): Add.
5757 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
5758 the first argument because it may become position-dependent, and unset
5759 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
5760 Add comments explaining these issues in more detail.
5761
5762 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

5845
5846 Update to the current gnulib CVS repository, and fix trigraph handling
5847 in Bison.
5848 * bootstrap: Update gnulib CVS repository URL.
5849 (symlink_to_dir): Encapsulate the code that guarantees the destination
5850 directory exists into...
5851 (check_dst_dir): ... this new function, and...
5852 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
5853 fail when copying files into lib/uniwidth/.
5854 * src/output.c (prepare_symbols): When writing yytname muscles, where
5855 symbol names will be encoded in C-string literals, tell quotearg to
5856 escape trigraphs. This used to be the default in gnulib.
5857 * tests/regression.at (Token definitions): Because of the change in
5858 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
5859 escapes trigraphs in symbol names. Thus, yytname no longer has
5860 trigraphs unnecessarily doubly escaped. Update test case output.
5861 Extend test case to be sure Bison's own error messages will no longer
5862 have trigraphs in symbol names unnecessarily escaped once.

6392 and add @symbol-number. In the nonterminal element, rename @number to
6393 @symbol-number. Discussed starting at
6394 <http://lists.gnu.org/archive/html/bison-patches/2007-10/msg00040.html>.

6408 (xsl:template match="point"): Remove.
6409 (xsl:template match="empty"): For consistency with --graph, don't

6415 (xsl:template name="ws-search"): Eliminate recursion.
6416 * src/print_graph.c (print_core): Don't print a reduction's lookahead

6480 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'
6481 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
6482 escaped later.

6488 * src/graphviz.c (start_graph, output_node, output_edge): Add
6489 whitespace to output for legibility.
6490
6491 Make xml2text.xsl and --report produce the same output, and remove the
6492 XML "conflicts" element since a conflict summary is easily extracted
6493 from the automaton.
6494 * data/xslt/bison.xsl: New.
6495 (xsl:template match="state" mode="bison:count-conflicts): New.
6496 * data/xslt/xml2text.xsl: Import bison.xsl.
6497 (xsl:template match="bison-xml-report"): Instead of styling the
6498 "conflicts" element, style the "automaton" element with mode

6500 conflicts for a state on the same line.
6501 (xsl:template match="conflicts"): Remove.
6502 (xsl:template match="conflict"): Remove.
6503 (xsl:template match="terminal"): Line-wrap the list of rules in which

6509 (xsl:template name="ws-search"): New.
6510 * data/xslt/xml2xhtml.xsl: Import bison.xsl.
6511 (xsl:template match="bison-xml-report"): Instead of styling the

6515 (xsl:template match="conflict"): Remove.
6516 (xsl:template match="automaton" mode="conflicts"): New.

6519 * src/conflicts.h (conflicts_output_xml): Remove prototype.
6520 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
6521 * src/print.c (print_grammar): Consistently wrap at the 66th column so
6522 the corresponding XSLT is easier. Also, never wrap between a word and
6523 the comma that follows it.
6524
6525 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
6526
6527 Improve C++ namespace support. Discussed starting at
6528 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
6529 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
6530 b4_namespace_close): New macros that interpret the %define variable
6531 "namespace" so its value can contain "::" to indicate nested
6532 namespaces.
6533 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
6534 the above macros.
6535 * data/lalr1.cc (b4_namespace): Likewise.
6536 * data/location.cc (b4_namespace): Likewise.
6537 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
6538 inside a new table in the general %define entry. Document `%define
6539 namespace' there as well. Point the %name-prefix entry to it since it
6540 explains it more completely in the case of C++.
6541 (C++ Bison Interface): Mention `%define namespace' instead of
6542 %name-prefix.
6543 (Table of Symbols): Remove the `%define push_pull' entry. The %define
6544 entry suffices.
6545 * tests/c++.at (Relative namespace references): New test case.
6546 (Absolute namespace references): New test case.
6547 (Syntactically invalid namespace references): New test case.
6548 * tests/input.at (C++ namespace reference errors): New test case.

6556 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
6557 (b4_percent_define_default): Record defining location as line 1 rather
6558 than 0 for the sake of synchronizing #line's, and define
6559 b4_percent_define_syncline(VARIABLE).
6560 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
6561 * src/muscle_tab.c (muscle_syncline_grow): New.
6562 (muscle_code_grow): Use muscle_syncline_grow.
6563 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and

6567 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
6568 remove some unused variables.
6569 (muscle_percent_define_default): Record defining location as line 1
6570 rather than 0 for the sake of synchronizing #line's, and define
6571 b4_percent_define_syncline(VARIABLE).
6572 (muscle_percent_define_check_values): Use
6573 muscle_percent_define_get_loc.
6574 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.

6580
6581 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
6582
6583 Fix some error-reporting macro bugs.
6584 * data/bison.m4 (b4_cat): New.
6585 (b4_error, b4_error_at): Use b4_cat to send error directives directly
6586 to stdout so they don't become arguments to other macros. Update
6587 comments and add examples.
6588 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
6589 add examples.
6590 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
6591 after printing the error directive so that M4 doesn't report subsequent
6592 problems that are induced by this problem.
6593 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
6594 instead of just in them. Recognize @\n in both places. Both expand to
6595 the empty string. Needed by b4_cat.
6596 * tests/skeletons.at (Complaining during macro argument expansion):
6597 New test case.
6598 (Fatal errors make M4 exit immediately): New test case.
6599

6611 * src/output.h (compute_pkgdatadir): Prototype.
6612
6613 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>

6627 Pull Parser Function, Parser Create Function, Parser Delete Function):
6628 Update declarations.

6633 definitions...
6634 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
6635 definitions...
6636 * data/push.c: ... to here and compute them from the value of the
6637 %define variable push_pull.
6638 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
6639 parsing requests here...
6640 * data/yacc.c: ... hack this to switch to push.c any time
6641 b4_use_push_pull_flag or the %define variable push_pull is set. This
6642 will go away when we mv push.c yacc.c.
6643 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
6644 push parsing is not supported since unused %define variables are
6645 reported anyway.

6679 Problem reported by Wojciech Polak.
6680 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.
6681 (xml_printf): Undo change I made on 21 September; that is,
6682 indent 2 spaces, not 1.
6683
6684 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
6685
6686 Pacify ./configure --enable-gcc-warnings.
6687 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
6688 `char const *' instead of `char *'.
6689 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
6690 local variable `sep'.
6691
6692 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
6693
6694 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
6695 elsewhere.
6696 * src/print-xml.c: Prefer "const" after types; that's more consistent.
6697 (xml_printf): Indent just 1 space for level.
6698 (e_char, xlate_char): Remove.
6699 (xml_escape_string): Rewrite to avoid undefined behavior (used
6700 storage that was freed from the stack).
6701 (xml_escape_n): Don't bother checking for subscript error.
6702
6703 2007-09-21 Wojciech Polak <polak@gnu.org>
6704

6753 Bruno Haible <bruno@clisp.org>
6754
6755 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists

6757
6758 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>
6759

6768 update output.
6769
6770 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
6771
6772 In impure push mode, don't allow more than one yypstate to be allocated
6773 since multiple impure parsers would corrupt yynerrs.
6774 * data/push.c (yypstate_allocated): New static global variable
6775 initialized to 0.
6776 (yypull_parse): If yypstate_new returns 0, don't report it as memory
6777 exhaustion if yypstate_allocated is 1, but still return 2.
6778 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
6779 already 1. Otherwise, set it to 1.
6780 (yypstate_delete): Set it to 0.
6781 * tests/push.at (Push Parsing: Multiple impure instances): New test
6782 case.

6853 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
6854
6855 Get rid of broken %no-parser, -n, and --no-parser implementation and
6856 documentation.
6857 * TODO: Don't mention them.
6858 * doc/bison.1: Likewise.
6859 * doc/bison.texinfo (Decl Summary): Likewise.
6860 (Bison Options): Likewise.
6861 (Option Cross Key): Likewise.
6862 * src/getargs.c (no_parser_flag): Remove global variable.
6863 (usage): Don't print description of -n and --no-parser.
6864 (long_options): Remove --no-parser entry here.
6865 (getargs): Remove -n case in the switch here.
6866 * src/getargs.h (no_parser_flag): Remove extern.
6867 * tests/regression.at (Web2c Actions): Remove comment that mentions
6868 --no-parser.
6869
6870 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
6871
6872 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
6873 name user variables starting with `yy'. Just pass NULL instead of a
6874 dummy local &yylval to yypush_parse.
6875 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
6876 starting with `yy'.
6877
6878 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
6879
6880 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
6881 true since it's then always used regardless of whether yyoverflow is
6882 defined. Reported by Christian Burger at
6883 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
6884 * THANKS: Add Christian Burger.
6885
6886 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
6887 node names: say "Decl Summary" not "Bison Declaration Summary".
6888
6889 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
6890
6891 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
6892 determine whether this function has already complained about an invalid
6893 value for a %define boolean variable, don't check whether Bison has
6894 ever examined the value. As written, the check was a tautology.
6895 Instead, record and check for this complaint using a separate muscle.
6896
6897 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
6898
6899 Fix push parsing memory leak reported by Brandon Lucia at
6900 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
6901 * THANKS: Add Brandon Lucia.
6902 * data/push.c (yypstate_delete): Free the stack if it was reallocated
6903 but the parse never completed and thus freed it.
6904 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
6905 * tests/testsuite.at: Include push.at.
6906 * test/push.at: New.
6907 (Push Parsing: Memory Leak for Early Deletion): New test case.
6908
6909 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
6910
6911 Improve handling of multiple S/R conflicts in the same state and of S/R
6912 conflicts involving multiple reductions.
6913 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
6914 set for a state here or Bison will abort if it is reassigned on a
6915 later conflicted reduction in the same state.
6916 Similarly, don't finalize and assign the solved conflicts report here
6917 or it will be lost if it is reassigned on a later conflicted reduction
6918 in the same state.
6919 (set_conflicts): Instead, assign them both here after all S/R conflicts
6920 in the state have been fully examined.
6921 * src/print.c (shift_set): Rename to...
6922 (no_reduce_set): ... this.
6923 (print_reductions): Update for rename, and add %nonassoc error action
6924 tokens to no_reduce_set so that, when printing the first remaining
6925 reduction on an error action token, the reduction is enclosed in
6926 brackets.
6927 (print_results): Update for rename.
6928 * tests/conflicts.at (Solved conflicts report for multiple reductions
6929 in a state): New test case.
6930 (%nonassoc error actions for multiple reductions in a state): New test
6931 case.
6932
6933 * src/main.c (main): Don't depend on C99 features.
6934
6935 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
6936
6937 * build-aux/.cvsignore: Add compile.
6938 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
6939 uniwidth.
6940
6941 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
6942
6943 * bootstrap (slurp): Create target directories that don't exist.
6944 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
6945
6946 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6947
6948 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
6949 than item number.
6950 * closure.c (closure): Likewise.
6951 * state.h (reductions): Comment sorting of rules.
6952 (state): Comment sorting of items.
6953
6954 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
6955
6956 Fix C++ test cases after recent Gnulib changes. Discussed starting at
6957 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
6958 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
6959 definition in order to avoid Gnulib headers since we don't use config.h
6960 here.
6961 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
6962 rather than AT_DATA so that config.h is included.
6963
6964 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
6965
6966 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
6967 instead of fprintf. Guard these functions with #if YYDEBUG instead of
6968 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
6969 and so that YYFPRINTF is guaranteed to be defined here.
6970
6971 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6972
6973 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
6974 with...
6975 (muscle_percent_define_check_values): ... this more helpful function.
6976 Again, it's not used yet, but it will be.
6977 * src/muscle_tab.h: Likewise.
6978
6979 Improve some comments in parser table construction.
6980 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
6981 (generate_states): Don't mention ruleset, which is internal to closure.
6982 * src/closure.c (closure): Explain sorting of core and itemset, which
6983 is required for this function to behave correctly.
6984 * src/closure.h (closure): Mention sorting.
6985
6986 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
6987
6988 * src/lalr.c (state_lookahead_tokens_count): For code readability,
6989 move the check for disabled transitions to an aver since conflict
6990 resolution hasn't happened yet.
6991
6992 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
6993 labels a state as inconsistent just because it has error transitions.
6994 The original form of this check appeared in revision 1.1 of lalr.c,
6995 which was committed on 1991-12-21. Now (at least), changing the
6996 consistency label on such a state appears to have no useful effect in
6997 any of the places it is examined, which I enumerate below. The key
6998 point to understanding each item in this enumeration is that a state
6999 with an error transition is labelled consistent in the first place only
7000 if it has no rules, so the check cannot matter for states that have
7001 rules. (1) Labelling a state as inconsistent will cause set_conflicts
7002 to try to identify its conflicts, and a state must have *rules* to have
7003 conflicts. (2) Labelling a state as inconsistent will affect how
7004 action_row sets the default *rule* for the state. (3) Labelling a
7005 state as inconsistent will cause build_relations to add lookback edges
7006 to *rules* in that state.
7007 * src/state.h (struct state): Word the comment for member consistent
7008 more carefully.
7009
7010 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
7011
7012 Don't depend on C99 features.
7013 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
7014 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
7015 * src/reader.c (check_and_convert_grammar): Fix for-loop.
7016 * src/state.c (state_mark_reachable_states): Fix for-loop.
7017 (state_remove_unreachable_states): Fix for-loop.
7018
7019 Don't widen struct state with member reachable just to temporarily
7020 record reachability. Instead, use a local bitset.
7021 * src/state.h (struct state): Remove member.
7022 * src/state.c (state_new): Don't initialize it.
7023 (state_mark_reachable_states): Rename to...
7024 (state_record_reachable_states): ... this, and use bitset.
7025 (state_remove_unreachable_states): Use bitset.
7026
7027 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
7028
7029 * src/Makefile.am (yacc): Quote target action commands properly so
7030 that the yacc script isn't corrupt. Reported by Hans Aberg at
7031 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
7032
7033 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
7034 the case of pure parsers. Reported by Frans Englich at
7035 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
7036 * THANKS: Add Frans Englich.
7037
7038 * NEWS (2.3a+): In the %code entry, reference section `Bison
7039 Declaration Summary' from the manual now since the %code summary has
7040 moved there.
7041 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
7042 in the rules section must be terminated by semicolons.
7043
7044 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
7045
7046 Extend the front-end API for %define variables to more completely
7047 mirror the back-end. This will be useful in the future.
7048 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
7049 Update comments to mention the new front-end counterparts of these
7050 macros.
7051 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
7052 for muscle_string_decode and muscle_location_decode.
7053 (muscle_string_decode): New static function.
7054 (muscle_location_decode): Use MUSCLE_COMMON_DECODE.
7055 (muscle_percent_define_get, muscle_percent_define_ifdef): New
7056 functions.
7057 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and
7058 muscle_percent_define_get to mimic the b4_percent_define_flag_if
7059 implementation more closely.
7060 (muscle_percent_define_invalid_value): New function.
7061 * src/muscle_tab.h (muscle_percent_define_get,
7062 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
7063 Prototype.
7064
7065 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
7066
7067 * NEWS (2.3a+): Mention yesterday's state-removal change.

7167
7168 DJGPP spefic issue. Inhibit the use of disallowed characters for
7169 file name genertion on Win98, WinXP, etc. These are |<>":?*\

7190
7191 Make it easy to share %define boolean variables between the front-end
7192 and back-end. Though not used yet, this will be useful in the future.
7193 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
7194 Bison uses of names rather than just skeleton uses of names.
7195 (b4_percent_define_get, b4_percent_define_ifdef): Rename

7209 b4_percent_define_loc(VARIABLE) to report the location of an invalid
7210 value for VARIABLE.
7211 (b4_percent_define_default): Save a special location in

7213 must later be reported as invalid.
7214 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
7215 functions.
7216 (muscle_percent_define_insert): Record the location of VARIABLE in
7217 muscle percent_define_loc(VARIABLE), and use it to report the previous
7218 location for a redefinition.

7230
7231 * src/print.c (lookahead_set, state_default_rule): Remove.
7232 (print_reductions): Replace state_default_rule invocation with
7233 equivalent use of yydefact, which was computed in token_actions in
7234 tables.c.
7235 (print_results): Don't allocate lookahead_set.
7236
7237 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
7238
7239 * data/lalr1.java: Prefix all private members with yy.
7240
7241 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
7242

7244 Sebastien Fricker at
7245 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
7246 * THANKS: Add Sebastien Fricker.
7247 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
7248 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

7251 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
7252
7253 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.

7260
7261 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
7262
7263 Undo my 2007-02-07 change, switching back to the c-strcase module
7264 introduced in the 2007-02-03 change. Bruno Haible reported that
7265 the 2007-02-07 change would be dangerous in Turkish if we add a
7266 language whose name contains "i", since "i" is not lowercase "I"
7267 in Turkish.
7268 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
7269 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
7270 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
7271 * m4/.cvsignore: Remove strcase.m4.
7272 * src/getargs.c: Revert 2007-02-07 change, as follows.
7273 Include c-strcase.h.
7274 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
7275
7276 2007-02-11 Bruno Haible <bruno@clisp.org>
7277
7278 Enable the Java related testsuite tests when the only Java compiler
7279 found is a gcj < 4.3. Discussed at
7280 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
7281 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
7282
7283 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
7284
7285 * data/Makefile.am: Update copyright date.
7286 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
7287 yypstate_new returns NULL.
7288 (yypstate_new): Return NULL if malloc does.
7289 * src/reader.c (packgram): Move translation of rule actions from the
7290 beginning of packgram to...
7291 (check_and_convert_grammar): ... here right before packgram is invoked
7292 so it's easier to write more complete comments, and remove redundant
7293 code.
7294
7295 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
7296
7297 As in semantic actions, make @$ in %initial-action, %destructor, and
7298 %printer imply %locations.
7299 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
7300 scanning @$.
7301 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
7302 (@$ in %initial-action implies %locations,
7303 @$ in %destructor implies %locations,
7304 @$ in %printer implies %locations): ... these new test cases.
7305
7306 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
7307
7308 Undo most of the 2007-02-03 change, switching to the strcase module
7309 now that gnulib strcase has been fixed.
7310 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
7311 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
7312 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
7313 * m4/.cvsignore: Add strcase.m4.
7314 * src/getargs.c: Revert 2007-02-03 change, as follows.
7315 Don't include c-strcase.h.
7316 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
7317 strcasecmp has "unspecified behavior" outside the POSIX locale,
7318 but it works fine in practice if at least one argument is ASCII,
7319 as is the case in Bison.
7320
7321 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
7322
7323 * tests/java.at: Skip tests if only one of javac/java is present.
7324 Reported by Joel E. Denny.
7325 * tests/atlocal.in: Adjust copyright years.
7326
7327 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
7328
7329 * data/lalr1.java (Stack): Work around old verifiers that disallow
7330 access to the private fields of an inner class, from the outer class.
7331 We can make Stack's fields public because user code doesn't have access
7332 to the instance of Stack used by parse(). Reported by Paul Eggert.
7333
7334 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
7335
7336 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
7337 the right spot for these files?
7338 * bootstrap.conf (gnulib_modules): Add c-strcase.
7339 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
7340 c-strncasecmp.c.
7341 * src/getargs.c: Include c-strcase.h.
7342 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
7343 to avoid unspecified behavior.
7344
7345 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
7346
7347 * doc/bison.texinfo (Decl Summary): Correct typo.
7348

7350
7351 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.

7355 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
7356 to above behavior.

7363 * bootstrap.conf: Add javacomp-script and javaexec-script.
7364 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
7365
7366 * data/Makefile.am: Add new files.
7367 * data/java-skel.m4: New.
7368 * data/java.m4: New.
7369 * data/lalr1.java: New.
7370
7371 * doc/bison.texinfo: Put "A Complete C++ Example" under
7372 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
7373 under Other Languages.

7375 * src/getargs.c (valid_languages): Add Java.
7376 * src/getargs.h (struct bison_language): Update size of string fields.
7377
7378 * tests/Makefile.am: Add java.at.
7379 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
7380 * tests/java.at: New.
7381 * tests/testsuite.at: Include it.
7382
7383 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
7384
7385 Clean up.
7386 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
7387 at_directive_argv arguments so these no longer have to be global
7388 variables. Also, update the implementation for the following changes.
7389 (fail_for_at_directive_too_many_args,
7390 fail_for_at_directive_too_few_args): Add at_directive_name argument.
7391 (at_directive_name): Remove as at_directive_argv[0] will be used for
7392 this now.
7393 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
7394 for the directive name.
7395 (at_directive_argc, at_directive_argv): Make these local within
7396 skel_lex instead of global.
7397 (INITIAL): Update directive start action for above changes.
7398 (SC_AT_DIRECTIVE_ARG): Rename to...
7399 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.

7403 * tests/skeletons.at (installed skeleton file name): Rename to...
7404 (installed skeleton file names): ... this.
7405
7406 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
7407
7408 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
7409 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
7410 Summary" not "Directives".
7411 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
7412 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
7413 since the former is now the more complete one.
7414 (Prologue Alternatives): Likewise and do the same for %defines.
7415 (Table of Symbols): Add summary of %code, add summary of %define, and
7416 move full %code documentation to...
7417 (Decl Summary): ... here for consistency with other entries in these
7418 sections.
7419 Move %define entry in order to keep this list alphabetized.
7420 Reword %define entry a little to put less emphasis on the skeleton
7421 concept, which most users shouldn't have to think about.
7422
7423 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
7424
7425 Adjust to recent gnulib changes.
7426 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.

7428 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
7429 * src/system.h: Don't include <stpcpy.h>; this is now done by
7430 <string.h>.
7431
7432 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
7433
7434 Simplify implementation of unqualified %code, implement macros for
7435 uniform treatment of boolean %define flags. Document %define.
7436 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
7437 b4_percent_code_ifdef): New.
7438 (b4_percent_code_get): Map unqualified %code to b4_percent_code().

7452 Discussed starting at
7453 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
7454 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
7455 (Bison Options): Document in --skeleton entry.
7456 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
7457 full_skeleton can't necessarily hold all of pkgdatadir.
7458 If the specified skeleton file name contains a `/', don't prepend
7459 pkgdatadir.
7460 * src/parse-gram.y (prologue_declaration): If the specified skeleton
7461 file name contains a `/', prepend the grammar file directory.
7462 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
7463 * skeletons.at: New file.
7464 (relative skeleton file names): New test case.

7473
7474 2007-01-17 Akim Demaille <akim@epita.fr>
7475
7476 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
7477 nonterminals.
7478 Use per-type %printer.
7479
7480 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>

7490 2007-01-16 Akim Demaille <akim@epita.fr>
7491
7492 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
7493 error code.
7494 (Calc++ Scanner): Exit with failure if we can't open the input
7495 file.
7496 Accept "-" standing for stdin.
7497 (Calc++ Top Level): Print the result only if the parsing was
7498 successful.

7500 2007-01-16 Akim Demaille <akim@epita.fr>
7501
7502 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
7503
7504 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
7505 and Joel E. Denny <jdenny@ces.clemson.edu>
7506
7507 Clean up %define and %code implementation in M4 some. Most
7508 importantly, rename all related macros to be in the b4_percent_define
7509 and b4_percent_code namespaces. Also, complete support for `.' in
7510 %define variable names and %code qualifiers.
7511 * data/bison.m4 (b4_check_user_names): Check for special
7512 "SKELETON-NAMESPACE(name)" macros instead of using two nested
7513 m4_foreach loops.
7514 (b4_get_percent_define, b4_get_percent_code): Rename to...
7515 (b4_percent_define_get, b4_percent_code_get): ... these.
7516 Extend documentation with examples.
7517 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
7518 b4_percent_define_skeleton_variables and
7519 b4_percent_code_skeleton_qualifiers.
7520 Expect any value for the %define variable `foo' to be stored in the
7521 macro named `b4_percent_define(foo)'; expect any %code blocks for the
7522 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
7523 expect any unqualified %code blocks to be stored in a macro named
7524 `b4_percent_code_unqualified'.
7525 Use m4_indir so that %define variable names and %code qualifiers can
7526 contain `.', which is allowed by the grammar parser.
7527 (b4_percent_define_default): New macro to set a default value for a
7528 %define variable.
7529 (m4_wrap): Update wrapped code, and fix some underquoting.
7530 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
7531 Expect grammar uses of %define variables and %code qualifiers to be
7532 defined in b4_percent_define_user_variables and
7533 b4_percent_code_user_qualifiers.
7534 * data/c++.m4: Use b4_percent_define_default rather than
7535 m4_define_default. Fix some underquoting. Skeleton usage of %define
7536 variable define_location_comparison now implies skeleton usage of
7537 %define variable filename_type.
7538 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
7539 data/push.c, data/yacc.c: Update macro names.
7540 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
7541 muscle names.

7543 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
7544
7545 DJGPP specific issues.
7546
7547 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
7548 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
7549
7550 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7551
7552 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
7553 run parsers in all tests so that Valgrind is invoked during
7554 maintainer-check-valgrind.
7555 (Duplicate representation of merged trees): Free all semantic values.
7556 (Duplicated user destructor for lookahead): Likewise.
7557
7558 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7559
7560 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
7561 command-line prefix.
7562 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
7563 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
7564 miss Valgrind messages.
7565 (Exploding the Stack Size with Malloc): Likewise.
7566
7567 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7568
7569 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
7570 locals. Reported by Juan Manuel Guerrero at
7571 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
7572 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
7573 Fix some indentation also.
7574 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
7575 explaining this issue.

7579
7580 Simplify union and prologue handling, and escape union and lex/parse
7581 params with digraphs.
7582 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
7583 values to the empty string since these are no longer guaranteed
7584 initialized by the front-end.
7585 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
7586 braces around b4_user_stype since this is no longer done by the
7587 front-end.
7588 * src/files.c, src/files.h (pre_prologue_obstack,
7589 post_prologue_obstack): Remove.
7590 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
7591 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
7592 with digraphs. This fixes lex params and parse params.
7593 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
7594 * src/output.c (prepare): Remove muscle insertion of the prologues.
7595 (output): Remove freeing of pre_prologue_obstack and
7596 post_prologue_obstack.
7597 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
7598 than prologue_augment for prologue parsing so you don't need prologue
7599 obstacks.
7600 (grammar_declaration): For %union RHS, use `braceless' instead of
7601 "{...}" so that braces are already stripped and code is escaped with
7602 digraphs.
7603 * src/reader.c (prologue_augment): Remove.
7604 (reader): Remove initialization of pre_prologue_obstack and
7605 post_prologue_obstack.
7606 * src/reader.h (prologue_augment): Remove.
7607
7608 * data/c.m4: Remove stray parenthesis.
7609
7610 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7611
7612 Remove quotes from variables names in %define directives and from
7613 qualifiers in %code directives, and restrict the characters that are
7614 allowed in them to M4-friendly ones. For %define, continue to support
7615 the quoted form as a deprecated feature. Discussed starting at
7616 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
7617 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
7618 %code.
7619 * doc/bison.texinfo (Prologue Alternatives): Update.
7620 (Decl Summary): In %defines entry, update mention of `%code requires'
7621 and `%code provides'.
7622 (C++ Location Values): Update %define uses.
7623 (Calc++ Parser Interface): Likewise.
7624 (Calc++ Parser): Likewise, and update `%code requires' uses.
7625 (Table of Symbols): Update %code documentation.
7626 * src/parse-gram.y (prologue_declaration): For %define variables, use
7627 `variable' instead of `STRING'.
7628 (grammar_declaration): For %code qualifiers, use `ID' instead of
7629 `STRING'.
7630 (variable): New nonterminal that takes an `ID' or a `STRING'.
7631 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
7632 and %define uses.
7633 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
7634 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
7635 (%define errors): Update %define uses.
7636
7637 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7638
7639 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
7640 instead of muscle_insert for %define values so that M4-special
7641 characters are replaced with digraphs.
7642 * tests/input.at (%define errors): Extend to check weird values.
7643
7644 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7645
7646 Instead of having skeletons declare all valid %define variables and
7647 %code qualifiers, provide macros that retrieve the associated values
7648 and build these lists automatically. Thus Bison will now warn when a
7649 variable or qualifier is not used by the skeleton in the current
7650 invocation regardless of whether it might sometimes be used by that
7651 skeleton in other invocations. Also, move all %define value macros to
7652 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
7653 form, which is replaced by %code.
7654 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
7655 (b4_check_user_names): ... this, and change the series of valid name
7656 arguments to a single list argument for names used in the skeleton
7657 similar to the existing list argument for names used in the grammar.
7658 Warn instead of complaining.
7659 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
7660 values and %code code, to format %code code properly, and to build
7661 lists of all %define variables and %code qualifiers used in the
7662 skeleton: b4_skeleton_percent_define_variables and
7663 b4_skeleton_percent_code_qualifiers.
7664 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
7665 Remove, and...
7666 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
7667 the skeleton names lists can finish building first. In place of
7668 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
7669 expect the lists b4_user_percent_define_variables and
7670 b4_user_percent_code_qualifiers.
7671 * data/c++.m4: Where setting default values for b4_parser_class_name,
7672 b4_location_type, b4_filename_type, b4_namespace, and
7673 b4_define_location_comparison, update their names to the
7674 b4_percent_define_ namespace.
7675 * data/glr.c: Don't use b4_check_percent_define_variables and
7676 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
7677 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
7678 (b4_parser_class_name, b4_namespace): Define these using
7679 b4_get_percent_define for parser_class_name and namespace.
7680 * data/location.cc: Use b4_get_percent_define.
7681 * data/push.c: Don't use b4_check_percent_define_variables and
7682 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
7683 * data/yacc.c: Likewise, and don't call m4_exit in
7684 b4_use_push_for_pull_if or m4_wrap code will never execute.
7685 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
7686 Rename to...
7687 (muscle_grow_user_name_list): ... this for consistency with the
7688 terminology used in bison.m4.
7689 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
7690 %define variable names, and rename muscle used_percent_define_variables
7691 to user_percent_define_variables.
7692 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
7693 user_percent_code_qualifiers.
7694 (content): Remove.
7695 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
7696 {CODE} form is no longer accepted.
7697 * tests/input.at (Reject bad %code qualifiers): Rename to...
7698 (Reject unused %code qualifiers): ... this, and update test output.
7699 (%define error): Update test output.
7700
7701 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
7702
7703 Check for unrecognized %define variables similar to checking for
7704 unrecognized %code qualifiers. Check for redefined %define variables.
7705 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
7706 generalizes...
7707 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
7708 (b4_check_percent_define_variables): New, also wraps it.
7709 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
7710 variables using b4_check_percent_define_variables.
7711 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
7712 all those exercised in the test suite and all those listed in the
7713 `Default values' section of c++.m4. Are there others?
7714 * data/push.c, data/yacc.c: Declare no valid %define variables.
7715 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
7716 similar to muscle_find, but it works even when the muscle stores a
7717 const value.
7718 (muscle_grow_used_name_list): New function for constructing the used
7719 name list muscles that b4_check_for_unrecognized_names requires.
7720 * src/parse-gram.y (prologue_declaration): Warn if a variable is
7721 %define'd more than once. Define the b4_used_percent_define_variables
7722 muscle with muscle_grow_used_name_list.
7723 (grammar_declaration): Abbreviate %code code with
7724 muscle_grow_used_name_list.
7725 * tests/input.at (%define errors): New.
7726
7727 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7728
7729 Provide warn_at, complain_at, and fatal_at function callbacks to the
7730 skeletons, and use this for %code qualifier complaints.
7731 * data/bison.m4 (b4_error_at): New, invoked by...
7732 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
7733 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
7734 @fatal_at(...@) directives.
7735 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
7736 qualifiers in b4_used_percent_code_qualifiers and to use
7737 b4_complain_at.
7738 * src/location.c, src/location.h (boundary_set_from_string): New global
7739 function.
7740 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
7741 function.
7742 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
7743 to b4_used_percent_code_qualifiers.
7744 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
7745 function.
7746 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
7747 (lineno): Rename to...
7748 (out_lineno): ... this so I don't misunderstand it again.
7749 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
7750 here; these newlines are in the input but not the output file.
7751 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
7752 (at_directive_perform): ... this new static function, and add handling
7753 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
7754 directives.
7755 * tests/input.at (Reject bad %code qualifiers): Update test output with
7756 locations and extend.
7757
7758 * tests/output.at (Output file name: [, Output file name: ]): Remove
7759 bogus comment about these tests failing.
7760
7761 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7762
7763 Clean up b4_check_percent_code_qualifiers a little.
7764 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
7765 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
7766 documentation and add examples.
7767 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
7768 qualifiers here.
7769
7770 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7771
7772 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
7773 unreliable -- especially when they're hidden inside another macro.
7774 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
7775 data/c.m4: Remove m4_divert(-1).
7776 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
7777 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
7778 m4_divert_push(0) and m4_divert_pop(0).
7779 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
7780 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
7781 pushed and popped by m4sugar, should be first on the stack.
7782
7783 Provide warn, complain, and fatal function callbacks to the skeletons.
7784 This provides more flexibility than m4_fatal, improves the error
7785 message format, and captures messages for translation. Discussed
7786 starting at
7787 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
7788 * data/bison.m4 (b4_error): New, invoked by...
7789 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
7790 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
7791 directives. Because these M4 macros might be called when the current
7792 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
7793 the previous removal of uses of m4_divert, which caused trouble.
7794 (b4_check_percent_code_qualifiers): Use b4_complain instead of
7795 m4_fatal to report unrecognized %code qualifiers.
7796 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
7797 push parser requests.
7798 * data/glr.c: Use b4_complain instead of m4_fatal to report
7799 non-deterministic push parser requests.
7800 Update @output usage to @output(...@) form.
7801 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
7802 report missing %defines. Update @output usage to @output(...@) form.
7803 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
7804 @output(...@) form.
7805 * src/main.c (main): Invoke skel_scanner_free.
7806 * src/scan-skel.h (skel_scanner_free): Prototype new function.
7807 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
7808 obstack_for_string from flex-scanner.h.
7809 (YY_DECL): Use to declare skel_lex static.
7810 (decode_at_digraphs): Remove; now handled in the new
7811 SC_AT_DIRECTIVE_ARG start condition.
7812 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
7813 functions.
7814 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
7815 at_directive_argv): New static globals.
7816 (INITIAL): Use fail_for_invalid_at.
7817 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
7818 recognize the start of a generalized `@directive(...@)' form and
7819 start...
7820 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
7821 directive args (using the new obstack_for_string), to decode the
7822 contained @ diagraphs, and to perform the directive. It recognizes
7823 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
7824 @output(...@).
7825 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
7826 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
7827 `@,'.
7828 (scan_skel): Initialize obstack_for_string on the first call.
7829 (skel_scanner_free): New function to free obstack_for_string.
7830 * tests/input.at (Reject bad %code qualifiers): Update test output.
7831
7832 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
7833
7834 Consolidate the 4 prologue alternative directives (%code, %requires,
7835 %provides, and %code-top) into a single %code directive with an
7836 optional qualifier field. Discussed at
7837 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
7838 * NEWS (2.3a+): Rewrite the existing entry for the prologue
7839 alternatives.
7840 * doc/bison.texinfo (Prologue Alternatives): Update.
7841 (Decl Summary): Update to %code "requires" and %code "provides".
7842 (Calc++ Parser): Update to %code "requires".
7843 (Table of Symbols): Remove entries for %requires, %provides, and
7844 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
7845 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
7846 are replaced by b4_percent_code_provides and b4_percent_code_requires,
7847 which are skeleton-specific.
7848 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
7849 declare what %code qualifiers it supports and to complain if any other
7850 qualifiers were used in the grammar.
7851 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
7852 and b4_user_code([b4_percent_code_provides]) in place of
7853 b4_user_requires and b4_user_provides.
7854 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
7855 Add b4_user_code([b4_percent_code_top]) and
7856 b4_user_code([b4_percent_code]).
7857 Invoke b4_check_percent_code_qualifiers.
7858 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
7859 PERCENT_REQUIRES): Remove.
7860 (grammar_declaration): Remove RHS's for %code-top, %provides, and
7861 %requires. Rewrite the %code RHS as the unqualified form defining the
7862 muscle b4_percent_code. Add another RHS for the qualified %code form,
7863 which defines muscles of the form b4_percent_code_QUALIFIER and the
7864 b4_used_percent_code_qualifiers muscle.
7865 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
7866 PERCENT_REQUIRES): Remove.
7867 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
7868 %code "requires" and %code "provides".
7869 * tests/input.at (Reject bad %code qualifiers): New.
7870
7871 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
7872
7873 Use the new code_props interface for destructors and printers.
7874 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
7875 printer_location members, and change the type of the destructor and
7876 printer members to code_props.
7877 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
7878 symbol_printer_get, semantic_type_destructor_set,
7879 semantic_type_printer_set, default_tagged_destructor_set,
7880 default_tagless_destructor_set, default_tagged_printer_set,
7881 default_tagless_printer_set): Use code_props in arguments and return
7882 types in place of char const * and location.
7883 (symbol_destructor_location_get, symbol_printer_location_get): Remove
7884 since the locations are now contained in the return of
7885 symbol_destructor_get and symbol_printer_get.
7886 * src/output.c (symbol_destructors_output, symbol_printers_output):
7887 Replace with...
7888 (symbol_code_props_output): ... this to eliminate duplicate code.
7889 (output_skeleton): Update to use symbol_code_props_output.
7890 * src/reader.c (symbol_should_be_used): Update use of
7891 symbol_destructor_get.
7892 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
7893 Update uses of the various _destructor_set and _printer_set functions.
7894 * src/symtab.c: (default_tagged_destructor_location,
7895 default_tagless_destructor_location, default_tagged_printer_location,
7896 default_tagless_printer_location): Remove since we...
7897 (default_tagged_destructor, default_tagless_destructor,
7898 default_tagged_printer, default_tagless_printer): ... change the type
7899 of these to code_props.
7900 (symbol_new, semantic_type_new, symbol_destructor_set,
7901 semantic_type_destructor_set, symbol_destructor_get,
7902 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
7903 symbol_check_alias_consistency, default_tagged_destructor_set,
7904 default_tagless_destructor_set, default_tagged_printer_set,
7905 default_tagless_printer_set): Update.
7906 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
7907 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
7908 code_props members.
7909 (symbol_print): Use SYMBOL_CODE_PRINT.
7910
7911 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
7912
7913 Use the new code_props interface for rule actions.
7914 * src/symlist.h (symbol_list): Replace action, action_location, and
7915 used members with a code_props action_props member.
7916 * src/reader.c (symbol_should_be_used, grammar_rule_check,
7917 grammar_midrule_action, grammar_current_rule_merge_set,
7918 grammar_current_rule_symbol_append, packgram): Update.
7919 * src/scan-code.h (translate_rule_action): Remove, no longer used.
7920 * src/scan-code.l (handle_action_dollar): Update.
7921 (translate_rule_action): Remove, no longer used.
7922 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
7923
7924 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
7925
7926 Use the new code_props interface in parse-gram.y.
7927 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
7928 Update all uses of translate_* functions to use the new code_props
7929 interface and to use gram_scanner_last_string_free and
7930 code_scanner_last_string_free where possible.
7931 (grammar_declaration): symbol_list_destructor_set and
7932 symbol_list_printer_set now perform the translation, so don't do it
7933 here. Use gram_scanner_last_string_free where possible.
7934 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
7935 translate_code): Remove, no longer used.
7936 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
7937 symbol_list_printer_set): Perform code translation here rather than
7938 depending on the caller to do so.
7939
7940 * src/symlist.h (struct symbol_list): Correct some documentation typos.
7941 * src/scan-gram.h (gram_last_string): Remove declaration.
7942 * src/scan-gram.l (last_string): Declare it static.
7943
7944 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
7945
7946 Encapsulate code properties and related functionality for the various
7947 destructors, printers, and actions into a code_props structure and
7948 interface. This patch merely implements code_props in scan-code.h and
7949 scan-code.l. Future patches will rewrite other modules to use it.
7950 Discussed starting at
7951 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
7952 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
7953 consistently initialize const structs that have an empty location
7954 field.
7955 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
7956 to ensure consistency.
7957 * src/scan-code.h (code_props): New structure.
7958 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
7959 function, macro, and const global variable for initializing a
7960 code_props with no code.
7961 (code_props_plain_init, code_props_symbol_action_init,
7962 code_props_rule_action_init, code_props_translate_code): The rest of
7963 the new code_props functional interface. Among other things, the init
7964 functions set the code_props kind field so that
7965 code_props_translate_code will know whether to behave like
7966 translate_symbol_action, translate_rule_action, or translate_code.
7967 These old translate functions must remain until all other modules are
7968 updated to use the new code_props interface.
7969 (code_scanner_last_string_free): New function similar to
7970 gram_scanner_last_string_free.
7971 (code_scanner_free): Add documentation.
7972 * src/scan-code.l: Implement the new interface.
7973 (code_lex): Make it static, add a code_props* argument, and remove the
7974 rule argument.
7975 (last_string): New static global similar to the one in scan-gram.l.
7976 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
7977 instead of rule.
7978 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
7979 code_props since Bison may one day use this information for destructors
7980 and printers.
7981 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
7982 (handle_action_dollar): Use symbol_list_n_get and set used flag
7983 directly since symbol_list_n_used_set is removed.
7984 (translate_action): Add a code_props* argument and remove the rule,
7985 action, and location arguments. Pass the code_props* on to code_lex.
7986 (translate_rule_action, translate_symbol_action, translate_code):
7987 Rewrite as wrappers around the new code_props interface.
7988 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
7989 it would eventually need to break the encapsulation of code_props.
7990
7991 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7992
7993 * etc/.cvsignore: New.
7994
7995 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7996
7997 Add maintainer-push-check to run maintainer-check using push parsing in
7998 place of pull parsing where available.
7999 * Makefile.am (maintainer-push-check): New.
8000 * data/bison.m4 (b4_use_push_for_pull_if): New.
8001 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
8002 appropriately based on their existing values.
8003 (yypush_parse): Don't print push-parser-specific diagnostics if push
8004 parsing is being used in place of pull parsing.
8005 * data/yacc.c: If push parsing should replace pull parsing, redirect to
8006 push.c.
8007 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
8008 variable, and insert b4_use_push_for_pull_flag into muscles.
8009 * tests/Makefile.am (maintainer-push-check): New.
8010
8011 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
8012
8013 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
8014 (whether successful or failed) so that yypush_parse can be invoked
8015 again to start a new parse using the same yypstate.
8016 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
8017 check multiple yypull_parse invocations on the same yypstate. For pull
8018 mode, extend to check multiple yyparse invocations.
8019 (Exploding the Stack Size with Alloca): Extend to try with
8020 %push-pull-parser.
8021 (Exploding the Stack Size with Malloc): Likewise.
8022
8023 * tests/calc.at (Simple LALR Calculator): Don't specify
8024 %skeleton "push.c" since %push-pull-parser implies that now.
8025 * tests/headers.at (export YYLTYPE): Don't check for the push
8026 declarations. Otherwise, this test case can't be used to see if push
8027 mode can truly emulate pull mode.
8028 * tests/input.at (Torturing the Scanner): Likewise.
8029 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
8030 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
8031 AT_YACC_IF, which now includes the case of push mode since %skeleton
8032 need not be used for push mode. This will be more intuitive once
8033 push.c is renamed to yacc.c.
8034
8035 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
8036
8037 For push mode, convert yyparse from a macro to a function, invoke yylex
8038 instead of passing a yylexp argument to yypull_parse, and don't
8039 generate yypull_parse or yyparse unless %push-pull-parser is declared.
8040 Discussed starting at
8041 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
8042 * data/bison.m4 (b4_pull_if): New.
8043 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
8044 * data/push.c: Improve M4 quoting a little.
8045 (b4_generate_macro_args, b4_parenthesize): Remove.
8046 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
8047 any time a pull parser is requested.
8048 Don't #define this as a wrapper around yypull_parse. Instead, when
8049 both push and pull are requested, make it a function that does that
8050 same thing.
8051 (yypull_parse): If there's a b4_prefix, #define this to
8052 b4_prefix[pull_parse] when both push and pull are requested.
8053 Don't define this as a function unless both push and pull are
8054 requested.
8055 Remove the yylexp argument and hard-code yylex invocation instead.
8056 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
8057 %push-parser.
8058 * src/getargs.c (pull_parser): New global initialized to true.
8059 * getargs.h (pull_parser): extern it.
8060 * src/output.c (prepare): Insert pull_flag muscle.
8061 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
8062 (prologue_declaration): Set both push_parser and pull_parser = true for
8063 %push-pull-parser. Set push_parser = true and pull_parser = false for
8064 %push-parser.
8065 * src/scan-gram.l: Don't accept %push_parser as an alternative to
8066 %push-parser since there's no backward-compatibility concern here.
8067 Scan %push-pull-parser.
8068 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
8069 instead of %push-parser.
8070 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
8071 prototype it in the module that calls yyparse.
8072 * tests/input.at (Torturing the Scanner): Likewise.
8073 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
8074
8075 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
8076
8077 Update etc/bench.pl. Optimize push mode a little (the yyn change
8078 deserves most of the credit).
8079 * Makefile.am (SUBDIRS): Add etc subdirectory.
8080 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
8081 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
8082 yytoken, yyval, and yyloc declarations to...
8083 (yyparse or yypush_parse): ... here to improve performance. For
8084 yypush_parse invocations after the first, be sure to assign yyn its old
8085 value again.
8086 (yypstate_new): Don't bother initializing the yyresult field since the
8087 initial value isn't used.
8088 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
8089 remove the #define that, in push mode, set it to yyps->NAME.
8090 * etc/Makefile.am: New.
8091 * etc/bench.pl: Remove and build it instead from...
8092 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
8093 "tests/bison" from the build directory by default rather than just
8094 invoking "bison" from $PATH.
8095 (calc_grammar): Update push parser code: don't declare yylval globally,
8096 don't define yyparse_wrapper, and don't #define yyparse.
8097 (bench_grammar): Update to check all working combinations of yacc.c,
8098 push.c, impure, pure, pull, and push.
8099
8100 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
8101
8102 For push mode, add pull wrappers around yypush_parse.
8103 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
8104 (yypull_parse): New function wrapping yypush_parse.
8105 (yyparse): New #define wrapping yypull_parse.
8106 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
8107 is declared.
8108 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
8109 prototype yylex in the module that calls yyparse, and don't prototype
8110 yyparse there. Otherwise, the yyparse expansion won't compile.
8111 * tests/input.at (Torturing the Scanner): Likewise.
8112
8113 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
8114
8115 Enable push parsers to operate in impure mode. Thus, %push-parser no
8116 longer implies %pure-parser. The point of this change is to move
8117 towards being able to test the push parser code by running the entire
8118 test suite as if %push-parser had been declared.
8119 * data/push.c (yypush_parse): For impure mode, remove the
8120 yypushed_char, yypushed_val, and yypushed_loc arguments.
8121 Instead, declare these as local variables initialized to the global
8122 yychar, yylval, and yylloc.
8123 For the first yypush_parse invocation only, restore the initial values
8124 of these global variables when it's time to read a token since they
8125 have been overwritten.
8126 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
8127 %push-parser.
8128 * tests/calc.at (Simple LALR(1) Calculator): Always declare
8129 %pure-parser along with %push-parser since this test case was designed
8130 for pure push parsers.
8131 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
8132 (AT_YACC_OR_PUSH_IF): New.
8133 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
8134 add a note that it's still wrong for some cases (as it has been for a
8135 while).
8136 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
8137 %push-parser no longer implies %pure-parser.
8138
8139 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
8140
8141 Remove some unnecessary differences between the pull parser code and
8142 the push parser code. This patch enables yynerrs in push mode.
8143 * data/push.c: Reformat M4 a little.
8144 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
8145 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
8146 because push mode is on. Instead, if pure mode is on, move yynerrs
8147 to...
8148 (b4_declare_parser_state_variables): ... here.
8149 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
8150 to yyps->NAME so it can be used in yypush_parse.
8151 (yypush_parse): Don't omit uses of yynerrs in push mode.
8152
8153 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
8154
8155 Fix bug such that the first pushed token's value and location are
8156 sometimes overwritten (sometimes by %initial-action) before being used.
8157 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
8158 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
8159 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
8160 more closely mimic the pull parser logic.
8161 Don't copy the pushed token to yychar, yylval, and yylloc until it's
8162 time to read a token, which is after any initialization of yylval and
8163 yylloc.
8164 (gottoken): Rename label to...
8165 (yyread_pushed_token): ... for clarity and to avoid infringing on the
8166 user namespace.
8167
8168 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
8169
8170 Rearrange initialization of the parser state variables so that the
8171 skeleton doesn't have to have a copy for pull mode and another for push
8172 mode. This patch also fixes at least a bug such that yylloc was not
8173 initialized (with b4_location_initial_line and
8174 b4_location_initial_column) upon calling yypush_parse. However, that
8175 initialization now overwrites the first token's location;
8176 %initial-action assigning @$ already did the same thing, and both bugs
8177 will be fixed in a later patch.
8178 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
8179 (b4_declare_parser_state_variables): Remove initialization of yytoken,
8180 yyss, yyvs, yyls, and yystacksize.
8181 (yypstate_new): Remove initialization of some yypstate fields: yystate,
8182 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
8183 yylsp.
8184 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
8185 yyps->NAME so it can be used in yypush_parse.
8186 (yyparse or yypush_parse): For yypush_parse, don't print the
8187 "Starting parse" diagnostic for invocations after the first.
8188 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
8189 yypush_parse, only do it for the first invocation.
8190 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
8191 initialization to occur in yypush_parse but only on the first
8192 invocation.
8193
8194 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
8195
8196 * data/push.c: Add CPP guards around push parser declarations in both
8197 the header and the code file.
8198 In the code file, move the push parser declarations to the same place
8199 they appear in the header file.
8200 Clean up the M4 some, especially the inconsistent underquoting in
8201 some b4_c_function_def and b4_c_function_decl uses.
8202
8203 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
8204
8205 Encapsulate the push parser state variables into an M4 macro so the
8206 push skeleton doesn't have to list them again for pull mode's yyparse.
8207 For push mode, remove yypush_parse's local equivalents of these
8208 variables to eliminate unnecessary copying between the two sets at
8209 run-time. This patch also fixes at least a bug related to multiple
8210 %initial-action invocations in push mode.
8211 * data/push.c (b4_declare_parser_variables): Rename to...
8212 (b4_declare_scanner_communication_variables): ... this for clarity and
8213 update both uses.
8214 (b4_declare_yyparse_variables): Remove and move its contents to the one
8215 spot where it was invoked.
8216 (b4_declare_parser_state_variables): New macro containing the parser
8217 state variables required by push mode.
8218 (struct yypstate): Replace all fields but yynew with
8219 b4_declare_parser_state_variables.
8220 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
8221 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
8222 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
8223 (yyparse or yypush_parse): For yyparse in pull mode, replace local
8224 parser state variable declarations with
8225 b4_declare_parser_state_variables.
8226 Don't initialize parser state variables when calling yypush_parse since
8227 yypstate_new already does that.
8228 Invoke the user's initial action only upon the first yypush_parse
8229 invocation.
8230 Remove all code that copies between the local parser state variables
8231 and the yypstate.
8232
8233 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
8234
8235 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
8236 prevent a name collision in a future patch where these names will
8237 sometimes be #define'd.
8238 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
8239 since it no longer has the same name as the existing argument.
8240 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
8241
8242 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
8243 and Joel E. Denny <jdenny@ces.clemson.edu>
8244
8245 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
8246 that the argument is case-insensitive, and there's no `=' here.
8247 For the %skeleton entry, mention that %language is better.
8248 (Bison Options): Likewise for --language and --skeleton. Move the
8249 --skeleton entry so that the `Tuning the parser' section is sorted
8250 alphabetically on long options.
8251 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
8252 %language directive in detail here; cross-reference the %language
8253 documentation instead.
8254 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
8255 `%require "2.3b"' so that the example is always up-to-date.
8256 (Table of Symbols): Add entries for %language and %skeleton.
8257 * examples/extexi (normalize): Instead of replacing every %require
8258 argument with the current Bison version, just substitute for
8259 `@value{VERSION}'. This guarantees that we're testing what actually
8260 appears in the documentation.
8261 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
8262 rather than `@VERSION@'.
8263
8264 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8265
8266 * NEWS: Reword the %language news a bit, and put it earlier.
8267
8268 * src/getargs.c (skeleton_arg): Last arg is now location const *.
8269 Rewrite to simplify the logic.
8270 (language_argmatch): Likewise.
8271 (program_name): We now own this var.
8272 * src/getargs.h (struct bison_language): Use char[] rather than
8273 const char *.
8274
8275 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
8276 Java is supported.
8277 * src/complain.c (program_name): Remove decl; no longer needed.
8278 * src/main.c (program_name): Remove; now belongs to getargs.
8279
8280 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
8281
8282 * NEWS: Document %language.
8283
8284 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
8285
8286 * data/c-skel.m4, data/c++-skel.m4: New files.
8287 * data/glr.c: Complain on push parsers.
8288
8289 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
8290 over %skeleton.
8291 (Decl Summary): Document %language and %skeleton.
8292 (Command line): Document -L.
8293
8294 * examples/extexi: Rewrite %require directive.
8295 * examples/calc++/Makefile.am: Pass VERSION to extexi.
8296
8297 * src/files.c (compute_exts_from_gc): Look in language structure
8298 for .y extension.
8299 (compute_file_name_parts): Check whether .tab should be added.
8300 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
8301 (language, skeleton_arg, language_argmatch): New.
8302 (long_options): Add --language.
8303 (getargs): Use skeleton_arg, add -L/--language.
8304 * src/getargs.h: Include location.h.
8305 (struct bison_language, language, skeleton_arg, language_argmatch): New.
8306 * src/output.c (prepare): Pick default skeleton from struct language.
8307 Don't dispatch C skeletons here.
8308 * src/parse-gram.y (PERCENT_LANGUAGE): New.
8309 (prologue_declaration): Add "%language" rule, use skeleton_arg.
8310 * src/scan-gram.l ("%language"): New rule.
8311
8312 * tests/calc.at: Test %skeleton and %language.
8313 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
8314 (AT_GLR_IF): Look for %skeleton "glr.cc".
8315 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
8316 (AT_YACC_IF): Reject %language.
8317
8318 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8319
8320 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
8321 since it wasn't used; only the typedef name 'semantic_type' is needed.
8322 Also, omit trailing white space.
8323
8324 * bootstrap: Sync from coreutils.
8325 (gnulib_extra_files): Add build-aux/announce.gen.
8326 (slurp): Adjust .gitignore files like .cvsignore files.
8327 * build-aux/announce-gen: Remove from CVS, since bootstrap
8328 now creates this.
8329
8330 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
8331
8332 Make %push-parser imply %pure-parser. This fixes several bugs; see
8333 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
8334 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
8335 pure_parser = true.
8336 * data/push.c: Don't bother testing b4_push_if when deciding whether
8337 to expand b4_declare_parser_variables globally.
8338 (yypush_parse): Likewise in here.
8339
8340 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
8341 (yy_reduce_print): Reformat M4 for readability.
8342
8343 2006-12-15 Bob Rossi <bob@brasko.net>
8344 and Joel Denny <jdenny@ces.clemson.edu>
8345
8346 * data/push.c (yypstate): Add typedef, and update all uses of
8347 struct yypstate to just yypstate.
8348 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
8349
8350 2006-12-14 Bob Rossi <bob@brasko.net>
8351
8352 * data/push.c (yypush_parse): Declare prototype regardless of
8353 %locations option.
8354
8355 2006-12-14 Bob Rossi <bob@brasko.net>
8356
8357 * data/push.c (yyparse): Remove the prototype and the #define when in
8358 push-parser mode.
8359
8360 2006-12-13 Bob Rossi <bob@brasko.net>
8361
8362 * data/push.c (yypstate_init): Rename to...
8363 (yypstate_new): ... this and use b4_c_function_def.
8364 (yypstate_delete): New.
8365 (yypush_parse): Change parameters yynval and yynlloc to be const.
8366 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
8367 yypstate_delete functions.
8368
8369 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
8370
8371 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
8372 strange test case titles. Reported by Bob Rossi.
8373
8374 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
8375
8376 * TODO: Add pointer to Sylvain Schmitz's work on static detection
8377 of potential ambiguities in GLR grammers.
8378
8379 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
8380
8381 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
8382 `bison ', use m4_index instead of m4_substr since chopping up a string
8383 containing M4-special characters causes problems here.
8384
8385 Fix a couple of bugs related to special characters in user-specified
8386 file names, and make it easier for skeletons to compute output file
8387 names with the same file name prefix as Bison-computed output file
8388 names.
8389 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
8390 b4_parser_file_name and b4_spec_defines_file instead of
8391 @output_parser_name@ and @output_header_name@, which are now redundant.
8392 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
8393 b4_parser_file_name, b4_spec_defines_file, and the new
8394 @basename(FILENAME@) instead of @output_parser_name@ and
8395 @output_header_name@, which inappropriately escaped the file names as
8396 C string literals.
8397 * src/files.c (all_but_ext): Remove static qualifier.
8398 (compute_output_file_names): Move `free (all_but_ext)' to...
8399 (output_file_names_free): ... here since all_but_ext is needed later.
8400 * src/files.h (all_but_ext): Extern.
8401 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
8402 exactly what MUSCLE_INSERT_STRING used to do.
8403 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
8404 characters are escaped properly.
8405 * src/output.c (prepare): Define muscle file_name_all_but_ext as
8406 all_but_ext.
8407 For pkgdatadir muscle, maintain previous functionality by using
8408 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
8409 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
8410 digraphs would never be expanded. Hopefully no one has M4-special
8411 characters in his Bison installation path.
8412 * src/scan-skel.l: Don't parse @output_header_name@ and
8413 @output_parser_name@ anymore since they're now redundant.
8414 In @output, use decode_at_digraphs.
8415 Parse a new @basename command that invokes last_component.
8416 (decode_at_digraphs): New.
8417 (BASE_QPUTS): Remove unused.
8418 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
8419 (Output file name): New tests.
8420
8421 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
8422
8423 Warn about output files that are generated by the skeletons and that
8424 conflict with other output files.
8425 * data/glr.c: Don't generate the header file here when glr.cc does.
8426 * src/files.c (file_names, file_names_count): New static globals.
8427 (compute_output_file_names): Invoke output_file_name_check for files
8428 not generated by the skeletons and remove existing checks.
8429 (output_file_name_check): New function that warns about conflicting
8430 output file names.
8431 (output_file_names_free): Free file_names.
8432 * src/files.h (output_file_name_check): Declare.
8433 * src/scan-skel.l: Invoke output_file_name_check for files generated by
8434 the skeletons.
8435 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
8436 (Conflicting output files): New tests.
8437
8438 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8439
8440 * doc/bison.texinfo: Fix a couple of typos.
8441
8442 2006-12-08 Bob Rossi <bob@brasko.net>
8443
8444 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
8445 Rename to...
8446 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
8447 update all uses.
8448 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
8449 (yypush_parse): Rename yypvars argument to yyps and remove redundant
8450 local pv.
8451 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
8452 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
8453
8454 2006-12-07 Bob Rossi <bob@brasko.net>
8455 and Joel Denny <jdenny@ces.clemson.edu>
8456
8457 * data/push.c (yypvarsinit): Change return type from void* to struct
8458 yypvars*. No longer cast to void* on return.
8459 (struct yypvars): Remove yylen since it need not be remembered between
8460 yypushparse invocations.
8461 (yypushparse): Don't copy between yylen and pv->yylen.
8462
8463 2006-12-05 Bob Rossi <bob@brasko.net>
8464
8465 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
8466 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
8467 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
8468 (struct yypvars): Remove b4_declare_parser_variables.
8469 (yypvarsinit): Remove init code for removed variables.
8470 (global scope): Do not declare b4_declare_parser_variables if
8471 push or pure mode.
8472 (yypushparse): Add b4_declare_parser_variables.
8473 Init new local variables, and remove init code for removed
8474 yypvars variables.
8475 (yyparse): Delete.
8476 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
8477 and yyparse for other modes.
8478 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
8479 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
8480 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
8481 (AT_PURE_LEX_IF): True if pure or push parser.
8482
8483 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
8484
8485 Document Yacc prologue alternatives and default %destructor's and
8486 %printer's as experimental. Don't mention Java yet. Discussed at
8487 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
8488 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
8489 (2.3a): Annotate this entry to say the old forms of these features were
8490 also experimental.
8491 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
8492 Table of Symbols): Say they're experimental. Comment out any mention
8493 of Java (we'll want this back eventually).
8494
8495 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
8496
8497 Support a file name argument to %defines. Deprecate `=' in
8498 %file-prefix, %name-prefix, and %output. Discussed at
8499 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
8500 * NEWS (2.3a+): Mention.
8501 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
8502 form of %defines, and remove `=' from entries for %file-prefix,
8503 %name-prefix, and %output.
8504 * src/parse-gram.y (prologue_declaration): Implement.
8505 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
8506 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
8507 all but one occurrence of %name-prefix.
8508 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
8509 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
8510 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
8511 occurrence of each of %file-prefix and %output. Add check for %defines
8512 with argument.
8513 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
8514 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
8515 Remove the `=' from %output.
8516
8517 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
8518
8519 Don't escape $ in test case titles since Autoconf 2.61 now does that
8520 correctly.
8521 * tests/actions.at (Default %printer and %destructor are not for error
8522 or $undefined): Here.
8523 (Default %printer and %destructor are not for $accept): Here.
8524 * tests/input.at (Invalid $n and @n): Here.
8525
8526 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
8527
8528 Rename <!> to <>. Discussed starting at
8529 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
8530 * NEWS (2.3a+): Update.
8531 * doc/bison.texinfo (Freeing Discarded Symbols, Table of Symbols):
8532 Update.
8533 * src/parse-gram.y (TYPE_TAG_NONE, generic_symlist_item): Implement.
8534 * src/scan-gram.l (INITIAL): Implement.
8535 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
8536 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
8537 comment.
8538 * tests/actions.at (Default tagless %printer and %destructor,
8539 Default tagged and per-type %printer and %destructor,
8540 Default %printer and %destructor are not for error or $undefined,
8541 Default %printer and %destructor are not for $accept,
8542 Default %printer and %destructor for mid-rule values): Update.
8543 * tests/input.at (Default %printer and %destructor redeclared,
8544 Unused values with default %destructor): Update.
8545
8546 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
8547
8548 Don't let %prec take a nonterminal.
8549 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
8550 token.
8551 * tests/input.at (%prec takes a token): New test checking that %prec
8552 won't take a nonterminal.
8553
8554 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
8555
8556 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
8557 it was double-quoted.
8558 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
8559 grammar is maintained with Bison's highest standards.
8560 * src/getargs.c: Fix some typos in Doxygen comments.
8561
8562 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
8563
8564 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
8565 later. Reported by Paul Eggert in
8566 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
8567 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
8568 * src/scan-code.l (translate_action): Don't bother invoking
8569 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
8570 (code_scanner_free): Instead of invoking
8571 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
8572 which frees more.
8573 * src/scan-gram.l (gram_scanner_free): Likewise.
8574 * src/scan-skel.l (scan_skel): Likewise.
8575
8576 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
8577
8578 * src/files.c (tr): Change return type to void.
8579 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
8580 has been called previously for the same key.
8581 (muscle_find): Return storage instead of value so that
8582 --enable-gcc-warnings doesn't produce warnings that the return discards
8583 const. aver that the value and storage are the same since storage
8584 could potentially be NULL when value is not.
8585 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
8586 same as 0.
8587
8588 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8589
8590 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
8591 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
8592 us a slightly cleaner distribution, and also works.
8593 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
8594 gnulib changes.
8595
8596 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
8597 and Paul Eggert <eggert@cs.ucla.edu>
8598
8599 Don't let Bison leak memory except when it complains.
8600 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
8601 (spec_defines_file, dir_prefix): Now char *, not const char *,
8602 since they are freed.
8603 * src/files.c: Likewise.
8604 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
8605 Likewise.
8606 (tr): Now operates in-place. All uses changed.
8607 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
8608 values.
8609 (compute_file_name_parts, compute_output_file_names): Don't store
8610 read-only data in variables that will be freed.
8611 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
8612 src_extension, and header_extension.
8613 (output_file_names_free): New public function to free
8614 spec_verbose_file, spec_graph_file, spec_defines_file,
8615 parser_file_name, and dir_prefix.
8616 * src/getargs.c (getargs): Don't store read-only data in variables that
8617 will be freed.
8618 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
8619 (which previously existed but was unused), and quotearg_free.
8620 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
8621 * src/muscle_tab.c: Likewise.
8622 (muscle_entry): Make the value char const *,
8623 and add a new storage member that is char * and can be freed.
8624 (muscle_entry_free): New private function.
8625 (muscle_init): Use it instead of free.
8626 (muscle_insert, muscle_grow): Update and use new storage member.
8627 (muscle_code_grow): Free the string passed to muscle_grow
8628 since it's not needed anymore.
8629 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
8630 add a new `char *code' member.
8631 ("{...}"): Declare semantic type as code.
8632 * src/scan-code.h (translate_rule_action):
8633 (translate_symbol_action, translate_code, translate_action): Return
8634 `char const *' rather than `char *' since external code should not free
8635 these strings.
8636 * src/scan-code.l: Likewise.
8637 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
8638 which is "{...}" in the parser.
8639 * tests/Makefile.am (maintainer-check-valgrind): Set
8640 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
8641 Valgrind.
8642 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
8643 complain.
8644 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
8645 expecting a non-zero exit status sets --leak-check=summary and
8646 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
8647 this case, and we don't want to hear about it.

8649 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8650
8651 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
8652 instead of from the template, to simplify configuration a bit.
8653 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
8654 and m4/wint_t.m4, as they are needed with the latest gnulib.
8655
8656 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
8657
8658 Disable unset/unused mid-rule value warnings by default, and recognize
8659 --warnings=midrule-values to enable them. Discussed starting at
8660 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
8661 * NEWS (2.3a+): Mention.
8662 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
8663 warnings): Add entry for midrule-values subargument.
8664 * src/reader.c (symbol_should_be_used): Don't return true just because
8665 the value is a set/used mid-rule value unless
8666 --warnings=midrule-values was specified.
8667 * tests/input.at (Unused values, Unused values before symbol
8668 declarations): Run tests with and without --warnings=midrule-values.
8669
8670 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
8671 than LIST_FREE directly.
8672
8673 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
8674
8675 Finish implementing --warnings=error, which should not be implied by
8676 --warnings=all (or by its synonyms -W and --warnings without
8677 subarguments).
8678 * src/complain.c (set_warning_issued): New function to report that
8679 warnings are being treated as errors and to record an error if so.
8680 Invoke...
8681 (warn_at, warn): ... here.
8682 * src/getargs.c (warnings_args, warnings_types): Reorder so that
8683 "error - warnings are errors" does not appear above "all - all of the
8684 above".
8685 (getargs): For -W and --warnings without subarguments, don't let
8686 FLAGS_ARGMATCH set warnings_error in warnings_flag.
8687 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
8688
8689 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
8690
8691 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
8692 empty subargument list. For example: `bison --warnings= parser.y'.
8693
8694 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
8695
8696 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
8697 the parser header file so that gcc doesn't warn.
8698
8699 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
8700
8701 Split the default %destructor/%printer into two kinds: <*> and <!>.
8702 Discussed starting at
8703 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
8704 * NEWS (2.3a+): Mention.
8705 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
8706 previous change today related to mid-rules.
8707 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
8708 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
8709 (TYPE_TAG_ANY): Add as <*>.
8710 (TYPE_TAG_NONE): Add as <!>.
8711 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
8712 for <*> and <!>.
8713 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
8714 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
8715 * src/symlist.c (symbol_list_default_new): Split into tagged and
8716 tagless versions.
8717 (symbol_list_destructor_set, symbol_list_printer_set): Split
8718 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
8719 SYMLIST_DEFAULT_TAGLESS.
8720 * src/symlist.h: Update symbol_list_default*_new prototypes.
8721 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
8722 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
8723 * src/symtab.c (default_destructor, default_destructor_location,
8724 default_printer, default_printer_location): Split each into tagged and
8725 tagless versions.
8726 (symbol_destructor_get, symbol_destructor_location_get,
8727 symbol_printer_get, symbol_printer_location_get): Implement tagged
8728 default and tagless default cases.
8729 (default_destructor_set, default_printer_set): Split each into tagged
8730 and tagless versions.
8731 * src/symtab.h: Update prototypes.
8732 * tests/actions.at (Default %printer and %destructor): Rename to...
8733 (Default tagless %printer and %destructor): ... this, and extend.
8734 (Per-type %printer and %destructor): Rename to...
8735 (Default tagged and per-type %printer and %destructor): ... this, and
8736 extend.
8737 (Default %printer and %destructor for user-defined end token): Extend.
8738 (Default %printer and %destructor are not for error or $undefined):
8739 Update.
8740 (Default %printer and %destructor are not for $accept): Update.
8741 (Default %printer and %destructor for mid-rule values): Extend.
8742 * tests/input.at (Default %printer and %destructor redeclared): Extend.
8743 (Unused values with default %destructor): Extend.
8744
8745 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
8746
8747 Don't apply the default %destructor/%printer to an unreferenced midrule
8748 value. Mentioned at
8749 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
8750 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
8751 like $@n instead of just @n so that the default %destructor/%printer
8752 logic doesn't see them as user-defined symbols.
8753 (symbol_is_dummy): Check for both forms of the name.
8754 * src/reader.c (packgram): Remove the `$' from each midrule symbol
8755 name for which the midrule value is referenced in any action.
8756 * tests/actions.at (Default %printer and %destructor for mid-rule
8757 values): New test.
8758 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
8759 for change to dummy symbol names.
8760
8761 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
8762
8763 Warn about unset midrule $$ if the corresponding $n is used.
8764 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
8765 $n usage.
8766 (packgram): Before invoking grammar_rule_check on any rule, make sure
8767 all actions have already been scanned in order to set `used' flags.
8768 Otherwise, checking that a midrule's $$ is set will not always work
8769 properly because the midrule check must forward-reference the midrule's
8770 parent rule.
8771 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
8772 warning.
8773
8774 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
8775
8776 More improvements to the documentation of the prologue alternatives:
8777 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
8778 Bison manual.
8779 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
8780 some text to clarify the relative importance of the new directives and
8781 to show how these directives may be viewed as code labels.
8782
8783 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
8784
8785 Similar to the recently removed %before-header, add %code-top as the
8786 alternative to the pre-prologue. Mentioned at
8787 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
8788 Also, let the prologue alternatives appear in the grammar section.
8789 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
8790 (prologue_declaration): Move the existing prologue alternatives to...
8791 (grammar_declaration): ... here and add %code-top.
8792 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
8793
8794 Clean up and extend documentation for the prologue alternatives.
8795 * NEWS (2.3a+): Describe prologue alternatives.
8796 * doc/bison.texinfo (Prologue): Move discussion of prologue
8797 alternatives to...
8798 (Prologue Alternatives): ... this new section, and extend it to discuss
8799 all 4 directives in detail.
8800 (Table of Symbols): Clean up discussion of prologue alternatives and
8801 add %code-top.

8839
8840 (Sync from coreutils.)
8841 Work also when the working directory (with e.g. coreutils sources)
8842 is version controlled with git, rather than CVS.
8843 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
8844 rather than CVS.
8845 In messages and comments, say e.g., "checked-out sources",
8846 rather than "CVS sources".
8847 (version_controlled_file): New function. Work for git as well as
8848 for CVS. Don't use grep's -q option.
8849 (slurp): Call it here, in place of CVS-specific code.
8850
8851 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
8852
8853 Fix testsuite for ./configure --enable-gcc-warnings:
8854 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
8855 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
8856 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
8857 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
8858 * test/regression.at (Diagnostic that expects two alternatives):

8896 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8897
8898 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
8899 variable was sometimes used without being initialized. This
8900 messed up the installation of the INSTALL file in some cases.
8901
8902 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
8903
8904 * bootstrap (usage, main program, symlink_to_gnulib): Add option
8905 --copy. Inspired by a suggestion from Bruno Haible.
8906
8907 2006-10-03 Jim Meyering <jim@meyering.net>
8908
8909 * bootstrap: Undo last change to this file, since now gnulib-tool
8910 sticks with the automake default in generating dependencies.
8911
8912 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8913
8914 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
8915 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
8916

8918
8919 * data/glr.c: Don't include <stdarg.h>; not used.
8920
8921 * NEWS: The -g and --graph options now output graphs in Graphviz
8922 DOT format, not VCG format.
8923 * doc/bison.1: Likewise.
8924 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
8925 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
8926 of this change in

8942 Output graphviz format rather than VCG format.
8943 * tests/.cvsignore: Remove *.vcg; add *.dot.
8944 * tests/output.at: Expect *.dot files, not *.vcg files.
8945
8946 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
8947 accommodates the 2006-10-08 change.

8986 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
8987
8988 Fix test failure reported by Tom Lane in
8989 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
8990 and try to make such failures easier to catch in the future.
8991 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
8992 that's now the caller's responsibility.
8993 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
8994 Set yychar = YYEOF if it's negative.
8995 * tests/actions.at (yylex): Abort if asked to read past EOF.

9004
9005 Fix problems with translating English-language diagnostics.
9006 * bootstrap: Fix bug introduced in recent bootstrap changes, with

9055
9056 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
9057
9058 * bootstrap (symlink_to_gnulib): New function.
9059 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
9060 to copies-of-gnulib.
9061 (cp_mark_as_generated, slurp, gnulib_files):
9062 Avoid making a copy if it's the same as the old version.

9065 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
9066
9067 * src/getargs.c (usage): Rework to use conventions similar to
9068 coreutils, to make translation a bit easier and the code a bit
9069 smaller. Problem reported by Tim Van Holder.
9070
9071 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
9072
9073 Use some of gnulib's new modules, taken from coreutils.
9074
9075 * bootstrap: Sync from coreutils, except add support for gnulib_files.
9076 * bootstrap.conf: New file.
9077 (gnulib_modules): Add configmake, inttypes, unistd.
9078 (XGETTEXT_OPTIONS): Add complain, complain_at,
9079 fatal, fatal_at, warn, warn_at, unexpected_end.
9080 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
9081 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
9082 (gl_EARLY): Add.
9083 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
9084 (gl_INIT): Add
9085 (GNULIB_AUTOCONF_SNIPPET): Remove.
9086 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
9087 the pickiest.
9088 * lib/.cvsignore: Add inttypes_.h.
9089 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
9090 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
9091 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
9092 no-longer-necessary initializations.
9093 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
9094 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
9095 use the unistd module.
9096 * src/system.h: Likewise.
9097 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
9098 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
9099 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
9100 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
9101 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
9102 * src/system.h: Include inttypes.h unconditionally, now that we
9103 use the inttypes module. Don't bother to include stdint.h, since
9104 inttypes.h now does that for us.
9105 (LOCALEDIR): Remove, now that we use the configmake module.
9106 * src/getargs.c: Include configmake.h.
9107 * src/main.c: Likewise.
9108 * src/output.c: Likewise.
9109 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
9110 not from $abs_top_builddir, since config.h moved.
9111
9112
9113 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
9114 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
9115
9116 * src/parse-gram.y (symbol_declaration): Don't put statements
9117 before declarations; it's not portable to C89.
9118 * src/scan-code.l (handle_action_at): Likewise.
9119
9120 * src/scan-code.l: Always initialize braces_level; the old code
9121 left it uninitialized and therefore had undefined behavior.
9122
9123 Don't attempt to redefine 'assert', since it runs afoul of
9124 systems where standard headers (mistakenly) include <assert.h>.
9125 Instead, define and use our own alternative, called 'aver'.
9126 * src/reader.c: Don't include assert.h, since we no longer
9127 use assert.
9128 * src/scan-code.l: Likewise.
9129 * src/system.h (assert): Remove, replacing with....
9130 (aver): New function, taking a bool arg. All uses changed.
9131 * src/tables.c (pack_vector): Ensure that aver arg is bool,
9132 not merely an integer.
9133
9134 2006-09-15 Bob Rossi <bob@brasko.net>
9135
9136 Add support for push parsing. Based on the original work of
9137 Odd Arild Olsen <oao@fibula.no>.
9138 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
9139 * data/c.m4 (YYPUSH): New.
9140 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
9141 * data/push.c: New file.
9142 * src/getargs.c (push_parser): New var.
9143 * src/getargs.h (push_parser): New declaration.
9144 * src/output.c (prepare): Add macro insertion of `push_flag'.
9145 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
9146 (prologue_declaration): Parse %push-parser.
9147 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
9148 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
9149 list of removed lines from the traces observed.
9150 (AT_CHECK_CALC_LALR): Added push parser tests.
9151
9152 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
9153
9154 * NEWS: Version 2.3a.
9155 * configure.ac (AC_INIT): Likewise.
9156
9157 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
9158 "#define YYSTYPE int" that caused "make maintainer-check" to fail
9159 due to header ordering dependencies. I don't know why the #define
9160 was there.
9161
9162 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
9163 runtime cost when YYDEBUG is not defined, and so that some tests
9164 that used to fail now work. Problem and initial suggestion by
9165 Paolo Bonzini.
9166 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
9167 * data/glr.cc (b4_parser_class_name):
9168 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
9169 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
9170 (yydebug_) [YYDEBUG]: New member.
9171 (yycdebug_): Now defined only if YYDEBUG.
9172 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
9173 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
9174 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
9175 if YYYDEBUG.
9176 (debug_stream, set_debug_stream, debug_level, set_debug_level):
9177 Define only if YYDEBUG.
9178 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
9179 set_debug_level.
9180 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
9181 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
9182 AT_CHECK_CALC_GLR_CC that are working now.
9183
9184 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
9185
9186 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
9187 We don't need them in glr.cc, and glr.c defines them.
9188 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
9189 assumes that defining it to anything is the same as defining
9190 it to 1. Problem reported by Paolo Bonzini.
9191
9192 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
9193
9194 * data/c.m4 (b4_null, b4_case): Define.
9195 * src/output.c (prepare_symbols): Use b4_null.
9196 (user_actions_output): Use b4_case.
9197
9198 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
9199
9200 * data/glr.c (b4_shared_declarations): Put start-header first,
9201 before any #includes that we generate, so that feature-test
9202 macros work. Problem reported by Michael Deutschmann in
9203 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
9204 * data/lalr1.cc: Likewise.
9205 * doc/bison.texinfo (Prologue): Document that feature-test macros
9206 should be defined before any Bison declarations.
9207 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
9208 that depend on location.hh after, not before, Bison decls, since
9209 we now include location.hh after the first user prologue.
9210
9211 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
9212 Sander Brandenburg in
9213 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
9214 Also, fix minor white space and comment issues.
9215 (Prologue): Mention that it's better to define feature-test macros
9216 before Bison declarations. Problem reported by Michael Deutschmann.
9217
9218 * README-cvs: Fix typo: "&" should be "&&". Problem reported
9219 by Jim Meyering.
9220 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
9221 This adjusts to recent gnulib changes.
9222
9223 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
9224
9225 Finish implementation of per-type %destructor/%printer. Discussed
9226 starting at
9227 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
9228 and
9229 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
9230 * NEWS (2.3+): Add a description of this feature to the default
9231 %destructor/%printer description.
9232 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
9233 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
9234 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
9235 list node contains a semantic type.
9236 * src/symtab.c, src/symtab.h: Extend with a table that associates
9237 semantic types with their %destructor's and %printer's.
9238 (semantic_type_from_uniqstr, semantic_type_get,
9239 semantic_type_destructor_set, semantic_type_printer_set): New functions
9240 composing the public interface of that table.
9241 (symbol_destructor_get, symbol_destructor_location_get,
9242 symbol_printer_get, symbol_printer_location_get): If there's no
9243 per-symbol %destructor/%printer, look up the per-type before trying
9244 the default.
9245 * tests/actions.at (Per-type %printer and %destructor): New test case.
9246 * tests/input.at (Default %printer and %destructor redeclared):
9247 Extend to check that multiple occurrences of %symbol-default in a
9248 single %destructor/%printer declaration is an error.
9249 (Per-type %printer and %destructor redeclared, Unused values with
9250 per-type %destructor): New test cases.
9251
9252 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
9253
9254 Require default %destructor/%printer to be declared using
9255 %symbol-default instead of an empty symbol list, and start working on
9256 new per-type %destructor/%printer. Discussed at
9257 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
9258 * NEWS (2.3+): Add %symbol-default to example.
9259 * bison.texinfo (Freeing Discarded Symbols): Likewise.
9260 (Table of Symbols): Add entry for %symbol-default.
9261 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
9262 (generic_symlist, generic_symlist_item): New nonterminals for creating
9263 a list in which each item is a symbol, semantic type, or
9264 %symbol-default.
9265 (grammar_declaration): Use generic_symlist in %destructor and %printer
9266 declarations instead of symbols.1 or an empty list.
9267 (symbol_declaration, precedence_declaration, symbols.1): Update actions
9268 for changes to symbol_list.
9269 * src/reader.c: Update for changes to symbol_list.
9270 * src/scan-code.l: Likewise.
9271 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
9272 * src/symlist.c, src/symlist.h: Extend such that a list node may
9273 represent a semantic type or a %symbol-default in addition to just an
9274 ordinary symbol. Add switched functions for setting %destructor's and
9275 %printer's.
9276 * tests/actions.at, tests/input.at: Add %symbol-default to all default
9277 %destructor/%printer declarations.
9278
9279 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
9280
9281 Whether the default %destructor/%printer applies to a particular symbol
9282 isn't a question of whether the user *declares* that symbol (in %token,
9283 for example). It's a question of whether the user by any means
9284 *defines* the symbol at all (by simply using a char token, for
9285 example). $end is defined by Bison whereas any other token with token
9286 number 0 is defined by the user. The error token is always defined by
9287 Bison regardless of whether the user declares it with %token, but we
9288 may one day let the user define error as a nonterminal instead.
9289 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
9290 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
9291 the meaning of "user-defined".
9292 * tests/actions.at (Default %printer and %destructor for user-declared
9293 end token): Rename to...
9294 (Default %printer and %destructor for user-defined end token): ...
9295 this.
9296
9297 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
9298 computation of whether to apply the default, don't maintain a list of
9299 every Bison-defined symbol. Instead, just check for a first character
9300 of '$', which a user symbol cannot have, and check for the error token.
9301
9302 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
9303
9304 Don't apply the default %destructor or %printer to the error token,
9305 $undefined, or $accept. This change fits the general rule that the
9306 default %destructor and %printer are only for user-declared symbols,
9307 and it solves several difficulties that are described in the new test
9308 cases listed below.
9309 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
9310 * tests/actions.at (Default %printer and %destructor are not for error
9311 or $undefined, Default %printer and %destructor are not for $accept):
9312 New test cases.
9313
9314 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
9315
9316 Allow %start after the first rule.
9317 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
9318 when parsing the first rule.
9319 (check_and_convert_grammar): Search for it here after all grammar
9320 declarations have been parsed. Skip midrules, which have dummy LHS
9321 nonterminals.
9322 * src/symtab.c (symbol_is_dummy): New function.
9323 * src/symtab.h (symbol_is_dummy): Declare it.
9324 * tests/input.at (%start after first rule): New test.
9325
9326 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
9327
9328 Redo some of the previous commit: add back the ability to use
9329 non-aliased/undeclared string literals since it might be useful to
9330 those declaring %token-table.
9331 * src/reader.c (check_and_convert_grammar): Undo changes in previous
9332 commit: don't worry about complaints from symbols_pack.
9333 * src/symtab.c (symbol_new, symbol_class_set,
9334 symbol_check_alias_consistency): Undo changes in previous commit: count
9335 each string literal as a new symbol and token, assign it a symbol
9336 number, and don't complain about non-aliased string literals.
9337 (symbols_pack): Since symbol_make_alias still does not decrement symbol
9338 and token counts but does still set aliased tokens to the same number,
9339 symbol_pack_processor now leaves empty slots in the symbols array.
9340 Remove those slots.
9341 * tests/regression.at (Undeclared string literal): Remove test case
9342 added in previous commit since non-aliased string literals are allowed
9343 again.
9344 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
9345 remove unnecessary string literal declarations.
9346 * tests/sets.at (Firsts): Likewise.
9347
9348 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
9349
9350 Don't allow an undeclared string literal, but allow a string literal to
9351 be used before its declaration.
9352 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
9353 symbols_pack complained.
9354 * src/symtab.c (symbol_new): Don't count a string literal as a new
9355 symbol.
9356 (symbol_class_set): Don't count a string literal as a new token, and
9357 don't assign it a symbol number since symbol_make_alias does that.
9358 (symbol_make_alias): It's not necessary to decrement the symbol and
9359 token counts anymore. Don't assume that an alias declaration occurs
9360 before any uses of the identifier or string, and thus don't assert that
9361 one of them has the highest symbol number so far.
9362 (symbol_check_alias_consistency): Complain if there's a string literal
9363 that wasn't declared as an alias.
9364 (symbols_pack): Bail if symbol_check_alias_consistency failed since
9365 symbol_pack asserts that every token has been assigned a symbol number
9366 although undeclared string literals have not.
9367 * tests/regression.at (String alias declared after use, Undeclared
9368 string literal): New test cases.
9369 (Characters Escapes, Web2c Actions): Declare string literals as
9370 aliases.
9371 * tests/sets.at (Firsts): Likewise.
9372
9373 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
9374
9375 In the grammar scanner, STRING_FINISH unclosed constructs and return
9376 them to the parser in order to improve error messages.
9377 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
9378 SC_BRACED_CODE, SC_PROLOGUE): Implement.
9379 * tests/input.at (Unclosed constructs): New test case.
9380 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
9381 seen.
9382
9383 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
9384 unused global.
9385
9386 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
9387
9388 Handle string aliases for character tokens correctly.
9389 * src/symtab.c (symbol_user_token_number_set): If the token has an
9390 alias, check and set its alias's user token number instead of its own,
9391 which is set to indicate the alias. Previously, every occurrence of
9392 the character token in the grammar overwrote that alias indicator with
9393 the character code.
9394 * tests/input.at (String aliases for character tokens): New test.
9395
9396 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
9397
9398 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
9399
9400 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
9401
9402 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
9403 to prevent failures when building on older platforms.
9404 Check for autopoint failure.
9405 Set XGETTEXT_OPTIONS to values that check for C format strings,
9406 so that translators are warned about them (this also helps
9407 prevent core dumps).
9408
9409 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
9410 function, since it simplifies our code a bit.
9411
9412 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
9413 rather than -W, so we don't get bogus warnings about sign comparisons.
9414 Add -Wpointer-arith, since that warning is useful (it reports code
9415 that does not conform to C89 and that some compilers reject).
9416 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
9417 since it's no longer needed.
9418
9419 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
9420
9421 Clean up scanners a bit.
9422 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
9423 definitions so gcc won't warn when obstack_for_string is unused.
9424 * src/scan-code.l: config.h and system.h are already #include'd by
9425 scan-code-c.c, so get rid of them here.
9426 * src/scan-gram.l: Likewise.
9427 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
9428 definitions rather than duplicating the rest of it.
9429 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
9430
9431 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
9432
9433 Suppress signed/unsigned comparison warnings for yycheck.
9434 * data/c.m4 (b4_safest_int_type): New macro.
9435 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
9436 a signed int type, cast it to b4_safest_int_type first.
9437 * data/yacc.c: Likewise.
9438 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
9439 also overwritten.
9440
9441 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
9442
9443 * doc/bison.texinfo: Fix some typos.
9444
9445 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
9446
9447 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
9448 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
9449
9450 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
9451 the latest gnulib does this a different way.
9452 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
9453 translation was patched, so stop omitting it.
9454
9455 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
9456
9457 Enable declaration of default %printer/%destructor. Make the parser
9458 use these for all user-declared grammar symbols for which the user does
9459 not declare a specific %printer/%destructor. Thus, the parser uses it
9460 for token 0 if the user declares it but not if Bison generates it as
9461 $end. Discussed starting at
9462 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
9463 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
9464 and
9465 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
9466 * NEWS (2.3+): Mention.
9467 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
9468 declare a %destructor for a mid-rule's semantic value. It's just
9469 impossible to declare one specific to it.
9470 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
9471 code. Describe default %destructor form.
9472 * src/parse-gram.y (grammar_declaration): Parse default
9473 %printer/%destructor declarations.
9474 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
9475 and symbol_destructor_location_get rather than accessing the destructor
9476 and destructor_location members of struct symbol.
9477 (symbol_printers_output): Likewise but for %printer's.
9478 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
9479 again.
9480 * src/symtab.c (default_destructor, default_destructor_location,
9481 default_printer, default_printer_location): New static global
9482 variables to record the default %destructor and %printer.
9483 (symbol_destructor_get, symbol_destructor_location_get,
9484 symbol_printer_get, symbol_printer_location_get): New functions to
9485 compute the appropriate %destructor and %printer for a symbol.
9486 (default_destructor_set, default_printer_set): New functions to set the
9487 default %destructor and %printer.
9488 * src/symtab.h: Prototype all those new functions.
9489 * tests/actions.at (Default %printer and %destructor): New test to
9490 check that the right %printer and %destructor are called, that they're
9491 not called for $end, and that $$ and @$ work correctly.
9492 (Default %printer and %destructor for user-declared end token): New
9493 test to check that the default %printer and %destructor are called for
9494 a user-declared end token.
9495 * tests/input.at (Default %printer and %destructor redeclared, Unused
9496 values with default %destructor): New tests to check related grammar
9497 warnings and errors.
9498
9499 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
9500
9501 Clean up handling of %destructor for the end token (token 0).
9502 Discussed starting at
9503 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
9504 and
9505 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
9506
9507 Make the skeletons consistent in how they pop the end token and invoke
9508 its %destructor.
9509 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
9510 state, which has token number 0, since this would invoke the
9511 %destructor for the end token.
9512 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
9513 until after shifting the end token, or else it won't be popped.
9514 * data/yacc.c (yyparse): Likewise.
9515
9516 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
9517 it's the end token. Upon termination, destroy an unshifted lookahead
9518 even when it's the end token.
9519 * data/lalr1.cc (yy::parser::parse): Likewise.
9520 * data/yacc.c (yyparse): Likewise.
9521
9522 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
9523 value warnings for the end token when the user gives the end token a
9524 %destructor.
9525
9526 * tests/actions.at (Printers and Destructors): Test all the above.
9527
9528 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
9529
9530 Update to latest gnulib and gettext versions.
9531 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
9532 Add fopen-safer.
9533 (gnulib_files): Add m4/warning.m4. Don't worry about files
9534 overwritten by autopoint.
9535 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
9536 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
9537 rejects them.
9538 Don't use autoreconf; instead, invoke autopoint etc. by hand,
9539 so that we can remove the intl files at a better time.
9540 (intl_files_to_remove): Remove aclocal.m4, since it gets
9541 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
9542 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
9543 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
9544 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
9545 Remove datarootdir hack; no longer needed.
9546 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
9547 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
9548 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
9549 strdup.h.
9550 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
9551 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
9552
9553 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
9554
9555 * bootstrap: Adjust to today's change to gnulib-tool by invoking
9556 it with --assume-autoconf='latest-stable'.
9557
9558 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
9559
9560 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
9561 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
9562 YYSTYPE' and `{'.
9563 * src/muscle_tab.h (muscle_grow): Replace the header comments with
9564 those from muscle_tab.c since the old ones are misleading.
9565
9566 2006-07-13 Akim Demaille <akim@epita.fr>
9567
9568 Support %define "KEY" {VALUE}.
9569 * src/scan-code.h, src/scan-code.l (translate_action)
9570 (translate_rule_action, translate_symbol_action, translate_code):
9571 Return char *, not const char *.
9572 * src/parse-gram.y (declaration): Rename as...
9573 (prologue_declaration): this.
9574 (string_content): Remove this nonterminal, use STRING.
9575 (braceless, content, content.opt): New nonterminal.
9576 Use them.
9577 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
9578 as value.
9579 * src/scan-gram.l (getargs.h): Don't include it.
9580
9581 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
9582
9583 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
9584 rather than a for-loop that declares a local bool variable. This
9585 should work around a compatibility problem with a Cray x1e C++
9586 compiler reported by Hung Nguyen in
9587 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
9588 The for-loop was introduced in the 2004-11-17 change but I don't
9589 know why it was needed.
9590
9591 2006-07-12 Akim Demaille <akim@epita.fr>
9592
9593 * data/c.m4: Comment changes.
9594
9595 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
9596
9597 * src/complain.c (error_message, ERROR_MESSAGE): New.
9598 To factor...
9599 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
9600 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
9601
9602 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
9603
9604 * NEWS: Instead of %union, you can define and use your own union type
9605 YYSTYPE if your grammar contains at least one <type> tag.
9606 Your YYSTYPE need not be a macro; it can be a typedef.
9607 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
9608 (Union Decl, Decl Summary): Document this.
9609 * data/glr.c (YYSTYPE): Implement this.
9610 * data/glr.cc (YYSTYPE): Likewise.
9611 * data/lalr1.cc (YYSTYPE): Likewise.
9612 * data/yacc.c (YYSTYPE): Likewise.
9613 * src/output.c (prepare): Output tag_seen_flag.
9614 * src/parse-gram.y (declaration, grammar_declaration):
9615 Use 'union_seen' rather than 'typed' to determine whether
9616 %union has been seen, since grammars can now be typed without
9617 %union.
9618 (symbol_declaration, type.opt, symbol_def):
9619 Keep track of whether a tag has been seen.
9620 * src/reader.c (union_seen, tag_seen): New vars.
9621 (typed): remove.
9622 * src/reader.h (union_seen, tag_seen, typed): Likewise.
9623 * src/scan-code.l (untyped_var_seen): New variable.
9624 (handle_action_dollar): Adjust to above changes.
9625 (handle_action_dollar, handle_action_at):
9626 Improve overflow checking for outlandish numbers.
9627 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
9628 avoid new diagnostics generated by above changes.
9629 * tests/regression.at (YYSTYPE typedef): Add test to check
9630 for type tags without %union.
9631
9632 * src/symlist.c (symbol_list_length): Return int, not unsigned
9633 int, since callers expect int. This may need to get revisited
9634 once we have proper integer overflow checking.
9635
9636 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
9637 object is now static.
9638
9639 * src/getargs.c (flags_argmatch): Return void, not int,
9640 to pacify ./configure --enable-gcc-warnings.
9641
9642 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
9643 since last_string is already defined to FLEX_PREFIX (last_string).
9644
9645 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9646
9647 Implement --warnings/-W.
9648 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
9649 replaced by...
9650 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
9651 Adjust callers.
9652 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
9653 (warnings_args, warnings_types): New.
9654 (getargs, short_options, long_options): Accept -W/--warnings.
9655 Sort the options by alphabetical order, upper case letter right
9656 before its lower case.
9657
9658 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
9659
9660 Change %merge result type clash warnings to errors. Discussed at
9661 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
9662 * src/reader.c (record_merge_function_type): Use complain_at.
9663 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9664 declared later): Update test case results.
9665
9666 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9667
9668 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
9669 to be in alphabetical order.
9670 (trace_args): Spelling fixes.
9671
9672 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
9673
9674 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
9675 so they don't collide with user-defined macros.
9676 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
9677 this was never guaranteed, and now that we're using gnulib stdint,
9678 which defines int_fast16_t to long int, the problem is exposed.
9679
9680 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
9681
9682 * data/c.m4 (b4_basename): Simplify a bit, since we don't
9683 need the full POSIX semantics (and weren't implementing them
9684 anyway).
9685
9686 Adjust to Autoconf 2.60 and today's gnulib.
9687 * bootstrap (gnulib_modules): Add stdint.
9688 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
9689 no longer copies it.
9690 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
9691 since stdint needs the former and wcwidth (which is now required
9692 by mbswidth) needs the latter.
9693 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
9694 work around a compatibility glitch between gettext 0.14.6 and
9695 Autoconf 2.60.
9696 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
9697 Do not check for uintptr_t, since new stdint module does the right
9698 thing.
9699 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
9700 Add stdint.h, stdint_.h, wcwidth.h.
9701 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
9702 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
9703 stdint.m4, wchar_t.m4, wcwidth.m4.
9704 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
9705 usual order for ../lib/*.h files.
9706 (file_name_split): Use last_component, not base_name, to adjust
9707 to gnulib changes.
9708 * src/parse-gram.h: Include <strverscmp.h> in the usual order
9709 for ../lib/*.h files.
9710 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
9711 Define unconditionally, since we now assume the stdint module.
9712 * src/scan-skel.l: Include <dirname.h>.
9713 (BASE_QPUTS): Use last_component, not base_name.
9714 * src/system.h: Include <unlocked-io.h> in the usual order
9715 for ../lib/*.h files. Include <stdint.h> unconditionally,
9716 since we now use the stdint module.
9717 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
9718 HAVE_UINTPTR_T, since we now use the stdint module.
9719 (base_name): Remove decl, since files now include <dirname.h>
9720 to get the decl.
9721
9722 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9723
9724 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
9725 New, default to 1.
9726 * data/yacc.c, data/glr.c, data/location.cc: Use them.
9727 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
9728 default.
9729 * tests/calc.at: Adjust.
9730
9731 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9732
9733 * data/c.m4 (b4_basename): New.
9734 (b4_syncline): Also output the location of its invocation (from
9735 the skeleton).
9736 (b4_user_action, b4_define_user_action, b4_user_actions)
9737 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
9738 (b4_user_stype): New.
9739 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
9740
9741 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9742
9743 In the grammar file, the first column is 1 not 0 on the first line as
9744 on every other line.
9745 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
9746 * tests/input.at (Torturing the Scanner): Update output.
9747
9748 * src/scan-gram.l (scanner_cursor): Declare it static.
9749
9750 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9751
9752 In warnings, say "previous declaration" rather than "first
9753 declaration".
9754 * src/symtab.c (redeclaration): Do that here.
9755 * src/reader.c (record_merge_function_type): In the case of a result
9756 type clash, report the previous declaration rather than the very first
9757 one in the grammar file.
9758 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9759 declared later): Add a third declaration to check this behavior.
9760 * tests/input.at (Incompatible Aliases): Update output.
9761
9762 2006-06-27 Akim Demaille <akim@epita.fr>
9763
9764 * doc/Doxyfile.in: New.
9765 * doc/Makefile.am: Use it.
9766 * src/lalr.h, src/symtab.h: Initial doxygenation.
9767
9768 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9769
9770 Don't miss %merge result type warnings just because the LHS types are
9771 declared after the %merge. This continues the effort of the previous
9772 patch.
9773 * src/reader.c (get_merge_function): Don't set the merger type yet.
9774 (record_merge_function_type): New function for setting the merger type
9775 and checking for clashes.
9776 (grammar_current_rule_merge_set): Set the location of the %merge for
9777 the current rule.
9778 (packgram): Invoke record_merge_function_type for each rule now that
9779 all symbol type declarations have been parsed.
9780 * src/reader.h (merger_list.type_declaration_location): New member
9781 storing the location of the first %merge from which the type for this
9782 merging function was derived.
9783 * src/symlist.h (symbol_list.merger_declaration_location): New member
9784 storing the location of a rule's %merge, if any.
9785 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9786 declared later): New test to catch the error fixed by the above patch.
9787
9788 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9789
9790 Get action warnings (grammar_rule_check) right even when symbol
9791 declarations appear after the rules. Discussed at
9792 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
9793 and
9794 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
9795 Don't mistake the type of $$ in a midrule to be that of its parent
9796 rule's $$.
9797 * src/reader.c (grammar_current_rule_end): Don't invoke
9798 grammar_rule_check yet since not all symbol declarations may have been
9799 parsed yet.
9800 (grammar_midrule_action): Likewise.
9801 Don't record whether the midrule's $$ has been used yet since actions
9802 haven't been translated yet.
9803 Record the midrule's parent rule and its RHS index within the parent
9804 rule.
9805 (grammar_current_rule_action_append): Don't translate the action yet
9806 since not all symbol declarations may have been parsed yet and, thus,
9807 warnings about types for $$, $n, @$, and @n can't be reported yet.
9808 (packgram): Translate the action and invoke grammar_rule_check now that
9809 all symbol declarations have been parsed.
9810 * src/scan-code.l (handle_action_dollar): Now that this is invoked
9811 after parsing the entire grammar file, the symbol list here in the case
9812 of a midrule is actually the midrule's empty RHS, so reference its
9813 parent rule's RHS where necessary.
9814 On the other hand, now that you can already know it's a midrule, you
9815 aren't forced to think $$ has the same type as its parent rule's $$.
9816 (handle_action_at): In the case of a midrule, reference the parent rule
9817 where necessary.
9818 * src/symlist.c (symbol_list_new): Initialize new midrule-related
9819 members.
9820 (symbol_list_length): Now that this is invoked after all rules have
9821 been parsed, a NULL symbol (rather than a NULL symbol list node)
9822 terminates a rule. symbol_list_print already does this correctly.
9823 * src/symlist.h (symbol_list.midrule_parent_rule,
9824 symbol_list.midrule_parent_rhs_index): New members so that midrules can
9825 remember their relationships with their parents.
9826 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
9827 fixed by the above patch.
9828 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
9829 implementing...
9830 (Unused values): ... this old test case and...
9831 (Unused values before symbol declarations): ... this new test case.
9832 This one is the same as `Unused values' except that all symbol
9833 declarations appear after the rules in order to catch the rest of the
9834 errors fixed by the above patch.
9835
9836 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9837
9838 More cleanup.
9839 * src/reader.c (current_rule): Declare it static since it's no longer
9840 used outside this file.
9841 (grammar_current_rule_action_append): Remove redundant arguments from
9842 translate_rule_action invocation.
9843 * src/reader.h (current_rule): Remove this unused extern.
9844 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
9845 * src/scan-code.l (translate_rule_action): Likewise.
9846
9847 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
9848
9849 Clean up yesterday's patch.
9850 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
9851 to...
9852 * src/reader.c (grammar_current_rule_action_append): ... here for
9853 consistency with grammar_current_rule_symbol_append.
9854 * tests/regression.at (Braced code in declaration in rules section):
9855 Make yyerror and yylex static as usual.
9856
9857 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
9858
9859 Fix bug that mistakes braced code in a declaration in the rules section
9860 to be a rule action. Mentioned at
9861 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
9862 * src/scan-gram.l: Move midrule action detection from the start of the
9863 scanning of any braced code to...
9864 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
9865 action. For readability, use $2 and @2 rather than the equivalent
9866 global variables.
9867 * tests/regression.at (Braced code in declaration in rules section):
9868 New test to catch the error fixed by the above patch.
9869
9870 Work on code readability some.
9871 * src/scan-code.l (current_rule): Get rid of this misleading and
9872 redundant declaration: it's actually extern'ed in reader.h.
9873 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
9874 translate_action): Add a rule argument and use it instead of the global
9875 current_rule.
9876 (translate_rule_action): This already receives current_rule through an
9877 argument, so pass it on to translate_action instead of assigning
9878 current_rule to current_rule.
9879 (translate_symbol_action, translate_code): Pass rule = NULL to
9880 translate_action.
9881
9882 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
9883
9884 Rename %before-definitions to %start-header and %after-definitions to
9885 %end-header. Don't use these declarations to separate pre-prologue
9886 blocks from post-prologue blocks. Add new order-independent
9887 declarations %before-header and %after-header as alternatives to the
9888 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
9889 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.

9899 prologue blocks with %*-header declarations.
9900 (Calc++ Parser): Likewise.
9901 (Decl Summary): Update names.
9902 (Table of Symbols): Update description.
9903 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
9904 (PERCENT_END_HEADER): ... this.
9905 (PERCENT_BEFORE_DEFINITIONS): Update to...
9906 (PERCENT_START_HEADER): ... this.
9907 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
9908 (declaration): Update token names and m4 macro names.
9909 When parsing %end-header and %start-header, invoke translate_code
9910 before muscle_code_grow, and no longer set global booleans to remember
9911 whether these declarations have been seen.
9912 Parse new %after-header and %before-header.
9913 * src/reader.c (before_definitions, after_definitions): Remove.
9914 (prologue_augment): Accept a new bool argument to specify whether to
9915 augment the pre-prologue or post-prologue.
9916 * src/reader.h (before_definitions, after_definitions): Remove these
9917 extern's.

9925
9926 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
9927
9928 Add comparison operators for C++ location classes. Discussed at
9929 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
9930 * data/c++.m4 (b4_define_location_comparison): New boolean %define
9931 declaration indicating whether filename_type has an operator==. If
9932 filename_type is `std::string', it defaults to `1', `0' otherwise.
9933 * data/location.cc: Iff b4_define_location_comparison is `1', add
9934 operator== and operator!= for class position and for class location.
9935
9936 Some minor fixes.
9937 * src/scan-action.l: Remove unused file.
9938 * src/symtab.c (symbol_printer_set): Use printer_location not
9939 destructor_location.

9944
9945 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
9946
9947 Don't put the pre-prologue in the header file. For the yacc.c code
9948 file and the glr.c header and code files, move the pre-prologue before
9949 the token definitions. Add new %before-definitions and
9950 %after-definitions to declare code that will go in both the header file
9951 and code file. Discussed at
9952 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
9953 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
9954 and
9955 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
9956 * NEWS (2.3+): Describe these changes.
9957 * data/glr.c (b4_pre_prologue): Move from within to before...
9958 (b4_shared_declarations): ... this.

9960 Add new b4_after_definitions at the end.
9961 * data/glr.cc (b4_pre_prologue): Replace with...
9962 (b4_before_definitions): ... this in the header file.
9963 (b4_after_definitions): New near the end of the header file.
9964 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
9965 code file right before including the header file.
9966 (b4_before_definitions): New in the previous position of
9967 b4_pre_prologue in the header file.
9968 (b4_after_definitions): New near the end of the header file.
9969 * data/yacc.c: Clean up some m4 quoting especially in the header file.
9970 (b4_token_enums_defines): In the code file, move to right before
9971 YYSTYPE for consistency with the header file.
9972 (b4_before_definitions): New right before b4_token_enums_defines in
9973 both the header and code file.
9974 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
9975 header and code file.
9976 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
9977 of prologues for %union dependencies.
9978 (Decl Summary): In %defines description, mention the effect of
9979 %before-definitions and %after-definitions on the header file.
9980 (Calc++ Parser): Forward declare driver in a %before-definitions rather
9981 than in the pre-prologue so that make check succeeds.
9982 (Table of Symbols): Add entries for %before-definitions and
9983 %after-definitions.
9984 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
9985 %before-definitions.
9986 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
9987 (declaration): Parse those declarations and append to
9988 b4_before_definitions and b4_after_definitions, respectively.
9989 * src/reader.c (before_definitions, after_definitions): New bools to
9990 track whether those declarations have been seen.
9991 (prologue_augment): Add to the post-prologue if %union,
9992 %before-definitions, or %after-definitions has been seen.
9993 * src/reader.h (before_definitions, after_definitions): New extern's.
9994 * src/scan-gram.l: Scan the new declarations.
9995 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
9996 prologue block in a %before-definitions or a %after-definitions based
9997 on whether the %union is declared.
9998 * tests/regression.at (Early token definitions with --yacc, Early token
9999 definitions without --yacc): Move tests for token definitions into the
10000 post-prologue since token names are no longer defined in the
10001 pre-prologue.
10002
10003 2006-06-20 Akim Demaille <akim@epita.fr>
10004
10005 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
10006 (symbol_get): Use it.
10007 * src/parse-gram.y: Use it.
10008
10009 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
10010
10011 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
10012 build succeeds when configured with --enable-gcc-warnings.
10013
10014 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10015
10016 * src/parse-gram.y (char_name): New function.
10017 (CHAR, STRING, string_content): For %printer, properly escape.
10018 (ID): Prefer fputs to fprintf.
10019 (id): Reindent to be consistent with other rules.
10020 Properly quote char.
10021
10022 The Translation Project changed its way of publishing translations
10023 to maintainers. I haven't received any responses to my request
10024 for supporting the old way, or for documenting the new way. I
10025 have modified 'bootstrap' to use screen scraping
10026 (in this case, HTML scraping). This is unreliable and inelegant,
10027 but I don't see any better way. Yuck.
10028 * bootstrap (TP_URL, WGET_COMMAND): New vars.
10029 (get_translations): New function, which uses HTML scraping to
10030 deduce locations of latest translations.
10031 Use this function to grab both bison and bison-runtime .po files.
10032 Don't bother priming the pump for the runtime-po domain any more,
10033 as it's now translated better than bison is.
10034
10035 2006-06-19 Akim Demaille <akim@epita.fr>
10036
10037 * src/scan-gram.l: No longer "parse" things after `%union' until
10038 `{'. Rather, return a single "%union" token.
10039 No longer make symbols: return strings, and leave the conversion
10040 to symbols to the parser.
10041 (SC_PRE_CODE, token_type): Remove.
10042 * src/parse-gram.y (%union): New field `character'.
10043 Sort tokens.
10044 (CHAR): New token.
10045 (ID, ID_COLON): Now that the scanner no longer makes them
10046 identifiers, adjust all uses to invoke symbol_get.
10047 (id_colon): New, wraps the conversion from string to symbol.
10048 (%union): Accept a possible union_name.
10049 (symbol): Now can be a char.
10050 * data/c.m4 (b4_union_name): Leave a default value.
10051 * data/glr.c, data/yacc.c: Use it.
10052
10053 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
10054
10055 For associating token numbers with token names for "yacc.c", don't use
10056 #define statements unless `--yacc' is specified; always use enum
10057 yytokentype. Most important discussions start at:
10058 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
10059 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
10060 and
10061 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
10062 * NEWS (2.3+): Mention.
10063 * data/c.m4 (b4_yacc_if): New.
10064 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
10065 token #define's.
10066 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
10067 on token name definitions.
10068 * src/getargs.c (usage): Capitalize `Yacc' in English.
10069 * src/output.c (prepare): Define b4_yacc_flag.
10070 * tests/regression.at (Early token definitions): Test that tokens names
10071 are defined before the pre-prologue not just before the post-prologue.
10072 Remove this test case and copy to...
10073 (Early token definitions with --yacc): ... this to test #define's.
10074 (Early token definitions without --yacc): ... and this to test enums.
10075
10076 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
10077
10078 * NEWS: Reword the post-2.3 change to not be so optimistic about
10079 removing the old "look-ahead" spelling.
10080 Update previous look-ahead/lookahead change reports.
10081 * REFERENCES: look-ahead -> lookahead (since that's
10082 what he actually wrote).
10083 * doc/refcard.tex: look ahead -> lookahead,
10084 look-ahead -> lookahead
10085
10086 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
10087
10088 For consistency, use `lookahead' instead of `look-ahead' or
10089 `look_ahead'. Discussed starting at
10090 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
10091 and then at
10092 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

10162
10163 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10164
10165 * TODO: Add request from Nelson H. F. Beebe to be able to install
10166 Bison without installing the yacc script.
10167
10168 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
10169
10170 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
10171 and yytext if they're already #define'd.
10172 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
10173 * src/scan-code-c.c: ... here.

10175 <config.h>.
10176
10177 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
10178
10179 Get Bison to build again when configured with --enable-gcc-warnings.
10180 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
10181 missing #include's.
10182 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
10183 loc argument as it shadows a global.
10184 * src/scan-gram.l: Remove stray comma that prevents boundary_set
10185 invocation.

10201 2006-06-06 Akim Demaille <akim@epita.fr>
10202
10203 Extract the parsing of user actions from the grammar scanner.
10204 As a consequence, the relation between the grammar scanner and
10205 parser is much simpler. We can also split "composite tokens" back
10206 into simple tokens.
10207 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
10208 * src/scan-gram.l (add_column_width, adjust_location): Move to and

10222 which is now, again, a separate token.
10223 Adjust all dependencies.
10224 Whereever actions with $ and @ are used, use translate_code.
10225 (action): Remove this nonterminal which is now useless.
10226 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
10227 (grammar_current_rule_action_append): Use translate_code.
10228 (packgram): Bound check ruleno, itemno, and rule_length.
10229 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
10230 (last_string, last_braced_code_loc, max_left_semantic_context)
10231 (scanner_initialize, scanner_free, scanner_last_string_free)
10232 (gram_out, gram_lineno, YY_DECL_): Move to...
10233 * src/scan-gram.h: this new file.

10239 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
10240 Move these declarations, and...
10241 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
10242 these to...
10243 * src/flex-scanner.h: this new file.
10244 * src/scan-gram.l (rule_length, rule_length_overflow)
10245 (increment_rule_length): Remove.
10246 (last_braced_code_loc): Rename as...
10247 (gram_last_braced_code_loc): this.
10248 Adjust to the changes of the parser.
10249 Move all the handling of $ and @ into...
10250 * src/scan-code.l: here.
10251 * src/scan-gram.l (handle_dollar, handle_at): Remove.
10252 (handle_action_dollar, handle_action_at): Move to...
10253 * src/scan-code.l: here.
10254 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
10255 scan-code.h, scan-code-c.c, scan-gram.h.
10256 (EXTRA_bison_SOURCES): Add scan-code.l.

10258 (yacc): Be robust to white spaces.
10259
10260 * tests/conflicts.at, tests/input.at, tests/reduce.at,
10261 * tests/regression.at: Adjust the column numbers.
10262 * tests/regression.at: Adjust the error message.
10263
10264 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
10265
10266 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
10267 Use Akim's wording from
10268 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.

10272 Between Bison releases, manually append `+' to the previous Bison
10273 release number, and use that as a signal to automatically print the
10274 ChangeLog's CVS Id keyword from --version. Discussed starting at
10275 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
10276 * ChangeLog: Add Id header.
10277 * configure.ac (AC_INIT): Append `+' to `2.3'.
10278 * src/.cvsignore: Add revision.c.
10279 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
10280 (BUILT_SOURCES): Add revision.c.
10281 (revision.c): New target rule. This file defines a new global variable
10282 named revision. It initializes it with either the Id from ChangeLog
10283 or, if VERSION doesn't contain `+', with the empty string.
10284 * src/getargs.c (version): Print the value of revision.
10285 * src/revision.h: Extern revision.

10291
10292 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10293
10294 * data/glr.c (YYRECOVERING): Define to be a function-like macro
10295 with no arguments, not as an object-like macro. This is for
10296 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
10297 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
10298 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
10299 Document this.
10300
10301 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
10302
10303 * src/getargs.c (usage): Back out yesterday's modification of the
10304 --help output so that we don't have to wait for translation before
10305 releasing 2.3.
10306
10307 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10308
10309 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
10310 Problem reported by Akim Demaille.
10311
10312 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
10313
10314 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
10315
10316 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10317
10318 * data/yacc.c (yy_reduce_print): Omit trailing white space in
10319 generated source code. Problem reported by Frans Englich in
10320 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
10321
10322 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
10323
10324 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
10325 shell, not within 'make', so that 'make' by an ordinary builder
10326 (using GNU make) does not worry about configuring gzip. This also
10327 works around a bug reported independently by Keith Thompson and by
10328 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
10329 stderr rather than stdout, messing up the build logs.
10330
10331 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
10332
10333 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
10334 to make sure that YYID will never be unused. This fixes a 'make
10335 maintainer-check' failure caused by the recent changes to the 'Trivial
10336 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
10337 not used.
10338 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
10339
10340 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
10341
10342 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
10343 state before an empty RHS is always resolved here. Only the location
10344 of that state is guaranteed to be resolved, and that's enough. This
10345 fixes the remaining bug reported by Derek M. Jones in
10346 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
10347 * tests/glr-regression.at (Uninitialized location when reporting
10348 ambiguity): Test the above case.
10349 Also, the embedded comments in this test case claim it checks the case
10350 of an empty RHS that has inherited the initial location. However, the
10351 corresponding LHS was already resolved, so yyresolveLocations didn't
10352 actually have reason to modify it. Fix this by forcing
10353 nondeterministic operation at the beginning of the parse.
10354
10355 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10356
10357 * data/c.m4 (b4_yy_symbol_print_generate):
10358 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
10359 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
10360 of the bugs reported today by Derek M Jones in
10361 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
10362 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
10363 defined to be a type name without parens or brackets.
10364 (Location Type): Similarly for YYLTYPE.
10365 * tests/regression.at (Trivial grammars): Put in a test for this
10366 bug that will be caught by 'make maintainer-check' (though not,
10367 alas, by 'make check' unless your compiler is picky).
10368
10369 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10370
10371 * NEWS: Version 2.2.
10372 * configure.ac (AC_INIT): Likewise.
10373
10374 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
10375
10376 * data/glr.c (yyreportTree): Make room in yystates for the state
10377 preceding the RHS. This fixes the segmentation fault reported by Derek
10378 M. Jones in
10379 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
10380 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
10381 to the user. Reported for yyreportTree by Derek M. Jones later in the
10382 same thread.
10383 * THANKS: Add Derek M. Jones.
10384 Update my email address.
10385 Fix typo in Steve Murphy's name.
10386
10387 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10388
10389 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
10390 checking against YYLAST that caused the parser to miss a potential
10391 alternative in its diagnostic.
10392 Problem reported by Maria Jose Moron Fernandez in
10393 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
10394 * data/lalr1.cc (yysyntax_error_): Likewise.
10395 * data/yacc.c (yysyntax_error): Likewise.
10396 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
10397 tokens, in case we run into an older C compiler.
10398 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
10399 Use them to check for the off-by-one error fixed above.
10400
10401 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
10402 YYSIZE_T, not size_t.
10403 * tests/regression.at (Trivial grammars): New test, to catch
10404 the error fixed by the above patch.
10405
10406 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
10407
10408 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
10409 scheme.
10410 Reported by Steve Murphy.
10411
10412 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
10413
10414 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
10415 * data/glr.cc: b4_location_flag is now b4_locations_flag.
10416
10417 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
10418
10419 Implement --trace=m4.
10420 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
10421 * src/output.c (output_skeleton): When set, pass -dV to m4.
10422
10423 Factor the handling of flags in m4.
10424 * src/output.c (prepare): Rename the muscle names debug, defines,
10425 error_verbose to debug_flag, defines_flag, error_verbose_flag.
10426 * data/c.m4: Adjust.
10427 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
10428 Use b4_define_flag_if to define other b4_FLAG_if macros.
10429 (b4_location_if): As a consequence, rename as...
10430 (b4_locations_if): this, for consistency.
10431 Adjust all the skeletons.
10432
10433 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
10434
10435 * etc/bench.pm: Shorten bench names.

10437 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
10438
10439 * src/output.h, src/output.c (error_verbose): Move to...
10440 * src/getargs.h, src/getargs.c: here.
10441 Sort the flags.
10442 Adjust dependencies.
10443
10444 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10445
10446 * data/c.m4 (b4_copyright): Put the special exception for Bison
10447 skeletons here, so we don't have to put it in each skeleton. All
10448 uses changed. Suggested by Akim Demaille. Also, wrap the
10449 copyright notice, in case it is longer than 80 columns. Replace
10450 comma by newline after title.
10451
10452 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10453
10454 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
10455 incompatibility, not a bug. Mention that it wasn't fixed as of
10456 flex 2.5.33.
10457
10458 2006-05-11 Akim Demaille <akim@lrde.epita.fr>

10464 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
10465
10466 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
10467 with the member "token".
10468 Reported by Martin Nylin.
10469
10470 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
10471
10472 * data/glr.c: Switch to Bison 2.2 special-exception language in
10473 the copyright notice. Use more-regular format for titles and
10474 copyright notices.
10475 * data/glr.cc: Likewise.
10476 * data/location.cc: Likewise.
10477 * data/yacc.cc: Likewise.

10485 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10486
10487 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
10488 that variable and the line breaks the bootstrap. Problem reported
10489 by Juan M. Guerrero.

10491 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

10514 and didn't really work.
10515 For the index, use @ifnotinfo, not @iftex.
10516 Minor cleanups of spacing and terminology.

10522
10523 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
10524
10525 Apply --prefix to C++ skeletons too: they change the namespace.
10526 The test suite already exercize these cases.
10527 * data/c++.m4 (b4_namespace): New.
10528 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
10529 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
10530 * data/yacc.c, data/glr.c: Remove a useless `[]'.
10531 * doc/bison.texinfo: Document it.
10532 (Option Cross Key): Use @multitable in all formats. It looks
10533 nicer, even in TeX outputs.
10534 (Rules): Use the same code whatever the output type is.
10535 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)

10569 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
10570 and "POSIX". Use more-modern syntax for URLs. Mention C++
10571 and ask for Java. Don't hardwire OS version numbers. Add
10572 copyright notice.
10573 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
10574 * src/conflicts.c (solved_conflicts_obstack): Now static.

10577
10578 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
10579 page. Say "you can use it" not "you may use it" as on the web page;
10580 we're describing capabilities not granting permission.

10587 (Uninitialized location when reporting ambiguity):
10588 Modify yylex so that it uses its argument, rather than trying
10589 to rely on ARGSUSED (which doesn't work for gcc with warnings).
10590 const char -> char const.
10591
10592 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):

10597
10598 * tests/glr-regression.at (Uninitialized location when reporting
10599 ambiguity): New test case.
10600 * data/glr.c (yyresolveLocations): New function, which uses
10601 YYLLOC_DEFAULT.
10602 (yyresolveValue): Invoke yyresolveLocations before reporting an
10603 ambiguity.
10604 * doc/bison.texinfo (Default Action for Locations): Note
10605 YYLLOC_DEFAULT's usage for ambiguity locations.
10606 (GLR Semantic Actions): Cross-reference those notes.
10607
10608 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
10609
10610 * tests/glr-regression.at (Leaked semantic values when reporting
10611 ambiguity): Remove unnecessary union and type declarations.
10612 (Leaked lookahead after nondeterministic parse syntax error): New test
10613 case.
10614 * data/glr.c (yyparse): Check for zero stacks remaining before
10615 attempting to shift the lookahead so that you don't lose it.
10616
10617 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
10618
10619 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
10620 * tests/glr-regression.at (Leaked semantic values when reporting
10621 ambiguity): New test case.
10622 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
10623 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
10624 now unnecessary yystackp parameter.
10625 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
10626 destructors can be called.
10627
10628 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
10629 in existing testcases.
10630
10631 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
10632
10633 Don't leak semantic values for parent RHS when a user action cuts the
10634 parser, and clean up related code a bit.
10635 * tests/glr-regression.at (Leaked merged semantic value if user action
10636 cuts parse): Rename to...
10637 (Leaked semantic values if user action cuts parse): ... this. Add check
10638 for leaked parent RHS values.
10639 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
10640 between an unresolved state (non-empty chain of semantic options) and
10641 an incomplete one (signaled by an empty chain).
10642 (yyresolveStates): Document the interface. Move all manipulation of a
10643 successfully or unsuccessfully resolved yyGLRState to...
10644 (yyresolveValue): ... here so that yyresolveValue always leaves a
10645 yyGLRState with consistent data and thus is easier to understand.
10646 Remove the yyvalp and yylocp parameters since they are always just
10647 taken from the yys parameter. When reporting a discarded merged value
10648 in debugging output, note that it is incompletely merged. Document the
10649 interface.
10650 (yyresolveAction): If resolving any of the RHS states fails, destroy
10651 them all rather than leaking them. Thus, as long as user actions are
10652 written to clean up the RHS correctly, yyresolveAction always cleans up
10653 the RHS of a semantic option. Document the interface.
10654
10655 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
10656

10661 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
10662

10671 __cplusplus && ! defined _STDLIB_H && !
10672 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||

10674 declarations of malloc and free, to avoid problems with
10675 incompatible declarations (using 'throw') C++'s stdlib.h. This
10676 should fix Debian bug 340012

10687
10688 * NEWS: Version 2.1a.

10707 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
10708 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
10709 messes up because C++ code is compiled in 32-bit mode but linked
10710 in 64-bit mode.

10715
10716 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
10717 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
10718
10719 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
10720 nodist_PROGRAMS, since we don't need to actually compile the
10721 example if we're just doing a plain 'make'. This avoids bothering
10722 the installer unnecessarily about problems due to weird C++
10723 compilers.

10728
10729 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
10730 than #include "...", and compile with -I'.'. The old method was
10731 not portable, according to Posix and the C standard, and it does
10732 not work with Sun C 5.7, where previous #line directives affect
10733 the working directory used in later #include "..." directives.

10751 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
10752 that '#include <string>' works.
10753
10754 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
10755 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
10756 "warning: sorry: semantics of inline function static data `const
10757 unsigned char translate_table[262]' are wrong (you'll wind up with
10758 multiple copies)".
10759
10760 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
10761 or, xor to not_, and_, or_, and xor_, respectively. This works
10762 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
10763 random system header somewhere that includes the equivalent of
10764 <iso646.h>.
10765
10766 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
10767 -E" works; it apparently doesn't work with PathScale EKO Compiler

10771
10772 During deterministic GLR operation, user actions should be able to
10773 influence the parse by changing yychar. To make this easier to fix and
10774 to make glr.c easier to evolve in general, don't maintain yytoken in
10775 parallel with yychar; just compute yytoken when needed.
10776 * tests/glr-regression.at (Incorrect lookahead during deterministic
10777 GLR): Check that setting yychar in a user action has the intended
10778 effect.
10779 * data/glr.c (yyGLRStack): Remove yytokenp member.
10780 (yyclearin): Don't set *yytokenp.
10781 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
10782 yychar rather than *yytokenp to determine the current lookahead.
10783 Compute yytoken locally when needed.
10784 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
10785 point to.
10786
10787 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
10788 after `--report' documentation.
10789
10790 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
10791
10792 * src/parse-gram.y (grammar_declaration): Location of printer
10793 symbol is @1, not list->location. Bug reported by twlevo.
10794 * tests/input.at (Incompatible Aliases): Adjust to above change.
10795
10796 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
10797
10798 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
10799 all the test at once. This makes the output easier to read in the
10800 normal case.
10801
10802 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
10803 got from <http://bro-ids.org/download.html>. The bug is that
10804 when two actions appeared in succession, the second one was
10805 scanned before the first one was added to the grammar rule
10806 as a midrule action. Bison then output the incorrect warning
10807 "parse.y:905.17-906.36: warning: unused value: $3".
10808 * src/parse-gram.y (BRACED_CODE, action): These are no longer
10809 associated with a value.
10810 (rhs): Don't invoke grammar_current_rule_action_append.
10811 (action): Invoke it here instead.
10812 * src/reader.c (grammar_midrule_action): Now extern.
10813 (grammar_current_rule_action_append): Don't invoke
10814 grammar_midrule_action; that is now the scanner's job.
10815 * src/reader.h (last_string, last_braced_code_loc):
10816 (grammar_midrule_action): New decls.
10817 * src/scan-gram.l (last_string): Now extern, sigh.
10818 (last_braced_code_loc): New extern variable.
10819 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
10820 rule already has an action.
10821 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
10822 * tests/input.at (AT_CHECK_UNUSED_VALUES):
10823 Add some tests to check that the above changes fixed the bug.
10824
10825 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
10826
10827 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
10828 All used changed. Check whether the symbol has a destructor,
10829 not whether it is typed.
10830 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
10831 that the values are still reported as unused. All line numbers
10832 adjusted.
10833
10834 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
10835
10836 Work around a bug in bro 0.8, which underparenthesizes its
10837 definition of YYLLOC_DEFAULT.
10838 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
10839 their arguments.
10840 * data/lalr1.cc: Likewise.
10841 * data/yacc.cc: Likewise.
10842
10843 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
10844
10845 Work around a bug in Pike 7.0, and give the Pike folks a
10846 better way to override the usual int widths.
10847 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
10848 user can override the types.
10849 (short): #undef, to work around a bug in Pike 7.0.
10850 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
10851 (union yyalloc.yyss): Use yytype_int16 rather than short.
10852 All uses changed.
10853 (yysigned_char): Remove.
10854 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
10855 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
10856 * tests/regression.at (Web2c Actions): Adjust to above changes.
10857
10858 * src/reader.c (check_and_convert_grammar): New function.
10859 (reader): Close the input file even if something went wrong during
10860 parsing. Minor file descriptor leak reported by twlevo.
10861
10862 * src/assoc.c (assoc_to_string): Use a default: abort (); case
10863 to pacify gcc -Wswitch-default.
10864 * src/scan-gram.l (adjust_location): Use a default: break; case
10865 to pacify gcc -Wswitch-default.
10866 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
10867 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
10868 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
10869 Move these decls to scan-skel.l, since they don't need to be
10870 visible elsewhere.
10871 * src/scan-skel.l: Accept the above decls.
10872 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
10873 is used.
10874
10875 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
10876
10877 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
10878 since we don't want to insist on a version number at the start
10879 of the changelog every time.
10880 * Makefile.maint: Sync from coreutils a bit better.
10881 (sc_trailing_blank): Renamed from sc_trailing_space.
10882 All uses changed.

10888 (sc_useless_cpp_parens, m4-check): Output line numbers.
10889 (changelog-check): Allow version only in head.
10890 * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
10891 satisfy new Makefile.maint rule.

10934
10935 Be a bit more systematic about using 'abort'.
10936 * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
10937 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
10938 Put 'default: abort ();' before some other case, to satisfy older
10939 pedantic compilers.
10940 * lib/bitset_stats.c (bitset_stats_init): Likewise.
10941 * lib/ebitset.c (ebitset_elt_find, ebitset_op3_cmp): Likewise.

10948 * src/conflicts.c (resolve_sr_conflict):
10949 Use a default case rather than one for the one remaining enum
10950 value, to catch invalid enum values as well.
10951 * src/lalr.c (set_goto_map, map_goto):
10952 Prefer "assert (FOO);" to "if (!FOO) abort ();".

10970 2006-01-19 Paul Eggert <eggert@cs.ucla.edu>
10971
10972 Fix some porting glitches found by Nelson H. F. Beebe.

10975 * src/state.c (transitions_to): Likewise.
10976 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
10977 that '#include <cstdlib>' works.

10979 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
10980 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
10981 for the benefit of some pre-C99 compilers.
10982
10983 * bootstrap: Undo changes to gnulib files that autoreconf made.
10984
10985 Minor fixups to get 'make maintainer-check' to work.
10986 * configure.ac: Don't use -Wnested-externs, as it's incompatible
10987 with the new verify.h implementation.
10988 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
10989 * data/glr.c (YYUSE): Depend on __GNUC__ as well.
10990 * data/yacc.c (YYUSE): Likewise.
10991 * data/lalr1.cc (yysyntax_error_): YYUSE (yystate).

10993 * src/parse-gram.y (declaration): Don't pass a string constant
10994 to a function that expects char *, since GCC might complain
10995 about the constant value.
10996 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
10997 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
10998 before #defining them.
10999 * tests/glr-regression.at
11000 (Incorrectly initialized location for empty right-hand side in GLR):
11001 In yyerror, use the msg arg.
11002 (Corrupted semantic options if user action cuts parse):
11003 (Incorrect lookahead during deterministic GLR):
11004 (Incorrect lookahead during nondeterministic GLR):
11005 Don't name a local var 'index'; it shadows string.h's 'index'.
11006
11007 2006-01-19 Akim Demaille <akim@epita.fr>
11008
11009 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
11010 location, not just parts of it.
11011
11012 2006-01-18 Paul Eggert <eggert@cs.ucla.edu>
11013
11014 * NEWS: Document the fact that multiple %unions are now allowed.
11015 * doc/bison.texinfo (Union Decl): Likewise.
11016 * TODO: This feature is now implemented, so remove it from
11017 the wishlist.

11020 (CVS_LIST): Use build-aux version if available.

11022 (syntax-check-rules): Add sc_no_if_have_config_h,
11023 sc_prohibit_assert_without_use, sc_require_config_h,
11024 sc_useless_cpp_parens.
11025 (sc_obsolete_symbols): Check for O_NDELAY.
11026 (sc_dd_max_sym_length): Track coreutils.
11027 (sc_unmarked_diagnostics): Look in all files, not just *.c.
11028 (sc_useless_cpp_parens): New rule.
11029 (news-date-check): Look for version or today's date.
11030 (changelog-check): Don't require version number near head.
11031 (copyright-check): Use current year instead of hardwiring 2005.
11032 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
11033 (announcement): Add --gpg-key-ID.
11034
11035 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
11036 with "file system".
11037
11038 Avoid undefined behavior that addressed just before the start of an
11039 array. Problem reported by twlevo.
11040 * src/reader.c (packgram): Prepend a new sentinel before ritem.
11041 * src/lalr.c (build_relations): Rely on new sentinel.
11042 * src/gram.c (gram_free): Adjust to new sentinel.

11049 yynewLookaheadNeeds.
11050 * data/glr-regression.at (Incorrect lookahead during nondeterministic
11051 GLR): In comments, change `lookahead status' to `lookahead need'.
11052
11053 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
11054
11055 * data/glr.c (yysplitStack): A little stylistic rewrite.
11056
11057 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
11058
11059 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
11060
11061 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
11062
11063 * doc/bison.texinfo: Fix some typos.
11064 (GLR Semantic Actions): New subsection discussing special
11065 considerations because GLR semantic actions might be deferred.
11066 (Actions): Mention look-ahead usage of yylval.
11067 (Actions and Locations): Mention look-ahead usage of yylloc.
11068 (Special Features for Use in Actions): Add YYEOF entry and mention it
11069 in the yychar entry.
11070 In the yychar entry, remove mention of the local yychar case (pure
11071 parser) since this is irrelevant information when writing semantic
11072 actions and since it's already discussed in `Table of Symbols' where
11073 yychar is otherwise described as an external variable.
11074 In the yychar entry, don't call it the `current' look-ahead since it
11075 isn't when semantic actions are deferred.
11076 In the yychar and yyclearin entries, add note about deferred semantic
11077 actions.
11078 Add yylloc and yylval entries discussing look-ahead usage.
11079 (Look-Ahead Tokens): When discussing yychar, don't call it the
11080 `current' look-ahead, and do mention yylval and yylloc.
11081 (Error Recovery): Cross-reference `Action Features' when mentioning
11082 yyclearin.
11083 (Table of Symbols): In the yychar entry, don't call it the `current'
11084 look-ahead.
11085 In the yylloc and yylval entries, mention look-ahead usage.
11086
11087 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
11088
11089 * tests/glr-regression.at: Update copyright year to 2006.
11090
11091 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
11092
11093 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
11094 use during nondeterministic operation to track which stacks have
11095 actually needed the current lookahead.
11096 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
11097 Allocate, deallocate, resize, and otherwise shuffle space for
11098 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
11099 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
11100 appropriately during nondeterministic operation.
11101 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
11102 members to store the current lookahead to be used by the deferred
11103 user action.
11104 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
11105 from which the RHS is taken. Set the lookahead members of the new
11106 yySemanticOption according to the lookahead status for stack yyk.
11107 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
11108 yyaddDeferredAction.
11109 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
11110 members of yySemanticOption before invoking yyuserAction, and then set
11111 them back to their current values afterward.
11112 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
11113 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
11114 * tests/glr-regression.at: Remove `.' from the ends of recent test case
11115 titles for consistency.
11116 (Leaked merged semantic value if user action cuts parse): In order to
11117 suppress lint warnings, use arguments in merge function, and assign
11118 char value < 128 in main.
11119 (Incorrect lookahead during deterministic GLR): New test case.
11120 (Incorrect lookahead during nondeterministic GLR): New test case.
11121
11122 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
11123
11124 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
11125 !yyvaluep as signal that no semantic value is available to print.
11126 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
11127 to print a semantic value.
11128
11129 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
11130
11131 * tests/glr-regression.at: For consistency with my newer test cases,
11132 don't thank myself.
11133
11134 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
11135
11136 * data/glr.c (yyresolveValue): When merging semantic options, if at
11137 least one user action succeeds but a later one cuts the parse, then
11138 destroy the semantic value before returning rather than leaking it.
11139 (yyresolveStates): If a user action cuts the parse and thus
11140 yyresolveValue fails, ignore the (unset) semantic value rather than
11141 corrupting the yyGLRState, and empty the semantic options list since
11142 the user actions should have called all necessary destructors.
11143 Simplify code with YYCHK.
11144 * tests/glr-regression.at (Corrupted semantic options if user action
11145 cuts parse): New test case.
11146 (Undesirable destructors if user action cuts parse): New test case.
11147 Before applying any of this patch, this test case never actually failed
11148 for me... but only because the corrupted semantic options usually
11149 masked this bug.
11150 (Leaked merged semantic value if user action cuts parse): New test
11151 case.
11152
11153 2006-01-05 Akim Demaille <akim@epita.fr>
11154
11155 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

11157 2006-01-04 Paul Eggert <eggert@cs.ucla.edu>
11158
11159 * data/c.m4 (b4_c_modern): New macro, with a new provision for
11160 _MSC_VER. Problem reported by Cenzato Marco.
11161 (b4_c_function_def): Use it.
11162 * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
11163 b4_c_modern.
11164 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
11165 than rolling our own.
11166
11167 2006-01-04 Akim Demaille <akim@epita.fr>
11168
11169 Also warn about non-used mid-rule values.
11170 * src/symlist.h, src/symlist.c (symbol_list): Add a mid_rule
11171 member.
11172 (symbol_list_new): Adjust.
11173 * src/reader.c (symbol_typed_p): New.
11174 (grammar_rule_check): Use it.
11175 (grammar_midrule_action): Bind a mid-rule LHS to its rule.
11176 Check its rule.
11177 * tests/input.at (AT_CHECK_UNUSED_VALUES): New.
11178 Use it.
11179 * tests/actions.at (Exotic Dollars): Adjust.
11180
11181 2006-01-04 Akim Demaille <akim@epita.fr>
11182
11183 * src/reader.c (grammar_midrule_action): If $$ is set in a
11184 mid-rule, move the `used' bit to its lhs.
11185 * tests/input.at (Unused values): New.
11186 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
11187
11188 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
11189
11190 * doc/bison.texinfo (Bison Options): Say more accurately what
11191 --yacc does.
11192 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
11193 about declarations in the grammar when in Yacc mode, as POSIX does
11194 not require a diagnostic when the grammar uses extensions.
11195
11196 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
11197
11198 Warn about dubious constructions like "%token T T".
11199 Reported by twlevo.
11200 * src/symtab.h (struct symbol.declared): New member.
11201 * src/symtab.c (symbol_new): Initialize it to false.
11202 (symbol_class_set): New arg DECLARING, specifying whether
11203 this is a declaration that we want to warn about, if there
11204 is more than one of them. All uses changed.
11205
11206 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
11207 Allow multiple %union directives, whose contents concatenate.
11208 * src/parse-gram.y (grammar_declaration): Likewise.
11209 Use muscle_code_grow, so that we don't need stype_line any more.
11210 All uses changed.
11211
11212 * src/muscle_tab.c (muscle_grow): Fix comment.
11213
11214 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
11215 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
11216 Update copyright year to 2006.
11217
11218 2006-01-03 Akim Demaille <akim@epita.fr>
11219
11220 Have glr.cc pass (some of) the calc.at tests.
11221 * data/glr.cc (b4_parse_param_orig): New.
11222 (b4_parse_param): Improve its definition, and bound it more
11223 clearly in the skeleton.
11224 (b4_epilogue): Append, instead of prepending, in order to keep
11225 #line consistency.
11226 Simplify the generation of auxiliary functions: locations and
11227 purity are mandated.
11228 (b4_global_tokens_and_yystype): Honor it.
11229 * data/location.cc (c++.m4): Don't include it.
11230 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
11231 and AT_SKEL_CC_IF.
11232 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
11233 AT_LALR1_CC_IF.
11234 Be sure to initialize the first position's filename.
11235 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
11236 mandated anyway.
11237 (AT_CHECK_CALC_GLR_CC): New.
11238 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
11239
11240 2006-01-02 Akim Demaille <akim@epita.fr>
11241
11242 * src/output.c (output_skeleton): Don't hard wire the inclusion of
11243 c.m4.
11244 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.
11245 * data/glr.cc: Do not include stack.hh.
11246
11247 2006-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
11248
11249 * data/glr.c: Reformat whitespace with tabs.
11250 (b4_lpure_formals): Remove this unused m4 macro.
11251 * tests/cxx-type.at: Reformat whitespace with tabs.
11252 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
11253 since it's a member. Rename type to isNterm for clarity.
11254
11255 2005-12-29 Akim <akim@sulaco.local>
11256
11257 Let glr.cc catch up with symbol_value_print.
11258 * data/glr.cc (b4_yysymprint_generate): Replace by...
11259 (b4_yy_symbol_print_generate): this.
11260 (yy_symbol_print, yy_symbol_value_print): Declare them.
11261
11262 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
11263
11264 * src/location.h (boundary): Note that a line or column equal
11265 to INT_MAX indicates an overflow.
11266 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
11267 (rule_length_overflow, increment_rule_length, add_column_width):
11268 New functions.
11269 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
11270 (<SC_BRACED_CODE>"}"):
11271 Use increment_rule_length rather than incrementing it by hand.
11272 (adjust_location, handle_syncline): Diagnose overflow.
11273 (handle_action_dollar, handle_action_at):
11274 Fix bug with monstrosities like $-2147483648.
11275 Remove now-unnecessary checks.
11276 (scan_integer): Verify assumptions and remove now-unnecessary checks.
11277 (convert_ucn_to_byte): Verify assumptions.
11278 (handle_syncline): New arg LOC. All callers changed.
11279 Don't store through a value derived from char const * pointer.
11280
11281 * src/reader.c (grammar_rule_check): Rewrite slightly to avoid
11282 GCC warnings.
11283
11284 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
11285
11286 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
11287 Remove unnecessary forward static decls.
11288
11289 2005-12-27 Akim Demaille <akim@epita.fr>
11290
11291 * src/reader.c (grammar_current_rule_check): Also check that $$
11292 is used.
11293 Take the rule to check as argument, hence rename as...
11294 (grammar_rule_check): this.
11295 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
11296 Rename as...
11297 (grammar_rule_begin, grammar_rule_end): these, for consistency.
11298 (grammar_midrule_action, grammar_symbol_append): Now static.
11299 * tests/torture.at (input): Don't rely on the default action
11300 being always performed.
11301 * tests/calc.at: "Set" $$ even when the action is "cut" with
11302 YYERROR or other.
11303 * tests/actions.at (Exotic Dollars): Instead of using unused
11304 values, check that the warning is issued.
11305
11306 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
11307
11308 * NEWS: Improve wording for unused-value warnings.
11309
11310 2005-12-22 Akim Demaille <akim@epita.fr>
11311
11312 * data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4
11313 (b4_yysymprint_generate): Rename as...
11314 (b4_yy_symbol_print_generate): this.
11315 Generate yy_symbol_print instead of yysymprint.
11316 Generate also yy_symbol_value_print, and use it.
11317
11318 2005-12-22 Akim Demaille <akim@epita.fr>
11319
11320 * NEWS: Warn about unused values.
11321 * src/symlist.h, src/symlist.c (symbol_list, symbol_list_new): Add
11322 a `used' member.
11323 (symbol_list_n_get, symbol_list_n_used_set): New.
11324 (symbol_list_n_type_name_get): Use symbol_list_n_get.
11325 * src/scan-gram.l (handle_action_dollar): Flag used symbols.
11326 * src/reader.c (grammar_current_rule_check): Check that values are
11327 used.
11328 * src/symtab.c (symbol_print): Accept 0.
11329 * tests/existing.at: Remove the type information.
11330 Empty the actions.
11331 Remove useless actions (beware of mid-rule actions: perl -000
11332 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
11333 * tests/actions.at (Exotic Dollars): Use unused values.
11334 * tests/calc.at: Likewise.
11335 * tests/glr-regression.at (No users destructors if stack 0 deleted):
11336 Likewise.
11337
11338 * src/gram.c (rule_useful_p, rule_never_reduced_p): Use
11339 rule_useful_p.
11340
11341 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
11342
11343 Undo 2005-12-01 tentative license wording change. The wording is
11344 still being reviewed by the lawyers, and we don't want to wait for
11345 them before publishing a test release. For now, revert to the
11346 previous wording.
11347 * NEWS: Undo 2005-12-01 change.
11348 * data/glr.c: Revert to previous license wording.
11349 * data/glr.cc: Likewise.
11350 * data/lalr1.cc: Likewise.
11351 * data/location.cc: Likewise.
11352 * data/yacc.c: Likewise.
11353
11354 * NEWS: Reword %destructor vs YYABORT etc.
11355 * data/glr.c: Use American spacing, for consistency.
11356 * data/glr.cc: Likewise.
11357 * data/lalr1.cc: Likewise.
11358 * data/yacc.c: Likewise.
11359 * data/yacc.c: Reformat comments slightly.
11360 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
11361 for consistency. Fix some spelling errors and reword recently-included
11362 text slightly.
11363 * tests/cxx-type.at: Cast results of malloc, for C++.
11364
11365 2005-12-21 Joel E. Denny <address@hidden>
11366
11367 * tests/cxx-type.at: Construct a tree, count the parents of shared
11368 nodes, and free each node once and only once. Previously, the memory
11369 for semantic values was leaked instead.
11370
11371 2005-12-21 Joel E. Denny <address@hidden>
11372
11373 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
11374 (yylval, yylloc): If pure, #define to yystackp->yyval and
11375 yystackp->yyloc similar to yychar and yynerrs.
11376 (yyparse): If pure, remove local yylval and yylloc. Add local
11377 yystackp to accommodate pure definitions of yylval and yylloc.
11378 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
11379 yylvalp and yyllocp to &yylval and &yylloc.
11380 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
11381 namespace. Previously, nerrs and char were missing, but lval and lloc
11382 weren't necessary.
11383 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
11384 yylvalp and yyllocp parameters since, if pure, these are now always
11385 accessible through yystackp. If not pure, they are still accessible
11386 globally.
11387 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
11388 `if (YYID (N))' to pacify lint.
11389
11390 2005-12-21 Akim Demaille <akim@epita.fr>
11391
11392 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
11393 destroy the RHS symbols of a rule.
11394 * data/yacc.c (yylen): Initialize to 0.
11395 Keep its value to the number of items to possibly shift.
11396 In particular, a regular successful parse that ends on YYFINAL by
11397 a (internal) YYACCEPT must not have yylen != 0.
11398 (yyerrorlab, yyreturn): Pop the RHS.
11399 Reorder a bit to emphasize the `shifting' bits of code.
11400 (YYPOPSTACK): Now accept a number of items to pop.
11401 * data/lalr1.cc: Likewise.
11402 * data/glr.c: Formatting changes.
11403 Use goto instead of fall through.
11404 * doc/bison.texinfo (Destructor Decl): Complete.
11405
11406 2005-12-20 Juan Manuel Guerrero <juan.guerrero@gmx.de>
11407
11408 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
11409 * djgpp/Makefile.maint: Fix PACKAGE variable computation.
11410 * djgpp/config.bat: Replace every occurence of the file name
11411 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
11412 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
11413 * djgpp/config.sed: Replace every occurence of the file name
11414 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
11415 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
11416 * djgpp/djunpack.bat: DJGPP specific file.
11417 * djgpp/fnchange.lst: DJGPP specific file.
11418 * djgpp/README.in: Add new information about how to unpack the bison
11419 source on MSDOS and other systems which have 8.3 file name restrictions
11420 using djunpack.bat and fnchange.lst.
11421
11422 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
11423
11424 * bootstrap (build_cvs_prefix): Remove; unused.
11425 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
11426 when getting gnulib.
11427
11428 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
11429
11430 * data/glr.c: Reorder typedef declarations for structs to match order
11431 of struct declarations.
11432 Rename yystack everywhere to yystackp except in yyparse where it's not
11433 a pointer.
11434 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
11435 consistency.
11436 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
11437 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
11438 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
11439 lint.
11440
11441 2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
11442
11443 * tests/sets.at (Accept): Fix typos in regular expression used to
11444 sed out the final state number.
11445
11446 Work around portability problem on Solaris 10: flex-generated
11447 files include <stdio.h> before <config.h>, which messes up
11448 because the latter defines __EXTENSIONS__. Address the problem
11449 by creating two new little files that include <config.h> first,
11450 then include the flex-generated files. Rewrite everyone else
11451 to include <config.h> first, as well.

11492 Prepend /*ARGSUSED*/, for lint's sake.
11493 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
11494 definition if 'lint' is defined.
11495 (YYID): New macro (or function, if lint).
11496 All uses of /*CONSTCOND*/0 replaced by YYID(0).
11497 * data/yacc.c: Likewise.
11498 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
11499 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.

11501 is C++ only.
11502 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
11503 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
11504 Use YYID(0) rather than 0, for lint.
11505 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

11512 Close memory leak reported by twlevo.
11513
11514 2005-12-06 "Joel E. Denny" <jdenny@ces.clemson.edu>

11517 all stacks.
11518 (yyparse): Iterate another stack in order to call user destructors.
11519 * tests/glr-regression.at (No users destructors if stack 0 deleted):
11520 New test case.
11521 (Duplicated user destructor for lookahead): This test now is expected

11523
11524 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
11525
11526 * NEWS: Document the following change.
11527 * data/yacc.c: Say "parser skeleton" rather than "file", since
11528 it's no longer just a file.
11529 * data/glr.c: Grant a special exception for C GLR parsers, that
11530 reads like the already-existing exception for C LALR(1) parsers.
11531 * data/glr.cc: Likewise.
11532 * data/lalr1.cc: Likewise.
11533 * data/location.cc: Likewise.

11541
11542 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
11543 Fix typos in previous change that broke 'make check'.
11544 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
11545 supported in C.
11546 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
11547 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
11548 We can revert this once things settle down.
11549
11550 * src/conflicts.c (conflicts_print): Don't print file name twice
11551 when %expect fails because there were no conflicts.
11552 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
11553 change.

11583 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
11584

11623
11624 Have glr.c include its header file when created.

11651 2005-11-09 Albert Chin-A-Young <china@thewrittenword.com>
11652
11653 * m4/cxx.m4, examples/Makefile.am: Don't build

11674
11675 2005-10-30 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
11676
11677 * data/glr.c (yyfill): Adjust comment.
11678 (yyresolveAction): Initialize default location properly
11679 for empty right-hand sides.
11680 (yydoAction): Ditto.
11681 Add comment explaining apparently dead code.

11683 (Incorrectly initialized location for empty right-hand side in GLR):
11684 New test.
11685
11686 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
11687
11688 * bootstrap (cleanup_gnulib): New function. Use it to clean up
11689 gnulib when interrupted. This fixes some race conditions and
11690 works around some portability problems (one noted by Paul
11691 Hilfinger).
11692
11693 2005-10-22 Akim <akim@epita.fr>
11694
11695 * Makefile.cfg: Adjust to config -> build-aux.

11713 Move to...
11714 * build-aux/prev-version, build-aux/announce-gen,

11717 2005-10-14 Akim Demaille <akim@epita.fr>
11718
11719 * examples/calc++/test: Use set -x only when VERBOSE.
11720
11721 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
11722
11723 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
11724 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
11725
11726 2005-10-13 Akim Demaille <akim@epita.fr>

11729 header file names.
11730 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
11731 additional checks.
11732 Use this to exercise C++ outputs in subdirs.
11733 Reported by Oleg Smolsky.
11734
11735 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
11736
11737 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
11738 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
11739 Problem reported by John P. Hartmann.
11740 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
11741 already defined it.
11742
11743 2005-10-12 Akim Demaille <akim@epita.fr>
11744

11752 (xlc and xlC_r) reported by John P. Hartmann.
11753 * data/location.cc (initial_column, initial_line): Remove.
11754 All uses replaced by 0 and 1.

11756 that xlc complains about.
11757 * src/scan-skel.l (skel_wrap): Likewise.
11758 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
11759 as __STDC__.
11760 * data/yacc.c (YYMODERN_C): New macro, which also looks at
11761 __STDC_VERSION__. Use it everywhere instead of looking at
11762 __STDC__ and __cplusplus.

11775 (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
11776 (YYCHK1):
11777 Use /*CONSTCOND*/ to suppress lint warnings.

11786
11787
11788 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.

11790
11791 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
11792
11793 Undo the parts of the unlocked-I/O change that substituted
11794 putc or puts for printf. This might hurt performance a bit,
11795 but some people prefer the printf style.
11796 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
11797 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
11798 All uses replaced by YYFPRINTF and YYDPRINTF.
11799 * data/yacc.c: Likewise.

11813
11814 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
11815 Use assignments rather than casts-to-void to suppress
11816 unused-variable warnings. This pacifies 'lint'.
11817 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
11818 unused-variable warnings.
11819
11820 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

11823
11824 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
11825
11826 Use unlocked I/O for a minor performance improvement on hosts like
11827 GNU/Linux and Solaris that support unlocked I/O. The basic idea
11828 is to use the gnlib unlocked-io module, and to prefer putc and
11829 puts to printf when either will work (since the latter doesn't
11830 come in an unlocked flavor).
11831 * bootstrap (gnulib_modules): Add unlocked-io.
11832 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
11833 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
11834 Prefer them to YYFPRINTF and YYDPRINTF if either will do,
11835 and similarly for puts and putc and printf.
11836 * data/yacc.c: Likewise.
11837 * lib/bitset.c (bitset_print): Likewise.
11838 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

11852 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

11854
11855 2005-10-02 Akim Demaille <akim@epita.fr>
11856
11857 * bootstrap (gnulib_modules): Add strverscmp.

11904
11905 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
11906 handle the lack of pipe/fork functionality on non-posix systems.

11927 * data/lalr1.cc: here.
11928 (location.hh): Include it after the user prologue, in case the
11929 filename type is defined by the user.
11930 Forward declation location and position before the pre-prologue.
11931 (yyresult_): Rename as...
11932 (yyresult): this, it's a local variable, not an attribute.
11933 * data/Makefile.am (dist_pkgdata_DATA): Adjust.

11975 (yyreduce_print_): Use the argument yyrule, not the former
11976 attribute yyn_.

11978 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
11979

11984 Include verify.h instead.
11985 * src/tables.c (tables_generate): Use new API for 'verify'.
11986

11988
11989 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
11990 local variables whose names begin with 'yy'.

11992 Trivial changes from Joel E. Denny.
11993
11994 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
11995 it itself.
11996 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
11997 don't use alloca any more.
11998
11999 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
12000 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
12001 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
12002 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
12003 to match yacc.c, to test more hosts.
12004
12005 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
12006
12007 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
12008 doesn't affect behavior.
12009 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
12010 Solaris, AIX, MSC.
12011 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
12012 This works a bit better with glibc, if user code has already included
12013 stdlib.h.
12014 * doc/bison.texinfo (Bison Parser): Document that users can't
12015 arbitrarily use malloc and free for other purposes. Document
12016 that <alloca.h> and <malloc.h> might be included.

12018 user must declare alloca.

12029 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
12030 (YYSTACK_ALLOC_MAXIMUM): Use it.
12031 (yysyntax_error): New function.
12032 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
12033 multiple syntax errors are reported, and alloca is being used.
12034 Instead, reallocate buffers twice as big each time, so that
12035 we waste at most half the allocated memory. Start with a small
12036 (128-byte) buffer that will suffice in most cases anyway.
12037 Use yysyntax_error to do most of the work.
12038
12039 * doc/bison.texinfo (Error Reporting, Table of Symbols):
12040 yynerrs is the number of errors reported, not the number of
12041 errors encountered.
12042
12043 * tests/glr-regression.at (Duplicated user destructor for lookahead):
12044 Mark it as expected to fail.
12045 Cast result of malloc; problem reported by twlevo@xs4all.nl.
12046 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
12047 Don't start user-code symbols with "yy", to avoid name space problems.
12048
12049 2005-09-19 Akim Demaille <akim@epita.fr>
12050
12051 Remove the traits, failed experiment.
12052 It never proved useful, and anyway because of the current
12053 definition, it was not possible to have several specialization of
12054 this traits, making it useless.
12055 * data/lalr1.cc (yy:traits): Remove.
12056 Inline its definitions in the parser class.
12057

12077 official release.
12078 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
12079 diagnostic.
12080 * src/output.c (prepare): Likewise.
12081 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
12082 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
12083 is not defined. This is an awful hack, but it's enough for now.
12084 All callers changed.
12085 * tests/glr-regression-at (make_value): Args are const pointers now,
12086 to avoid GCC warning.
12087 (Duplicated user destructor for lookahead): New test. Currently
12088 skipped. It fails on my host but I'm not sure it'll always fail.
12089
12090 2005-09-16 Akim Demaille <akim@epita.fr>
12091
12092 * src/symtab.h (struct symbol): Declare the printer and destructor
12093 as const, to avoid accidental calls to free.
12094 (symbol_destructor_set, symbol_printer_set): Adjust.
12095 * src/symtab.c: Adjust.
12096
12097 2005-09-16 Akim Demaille <akim@epita.fr>

12103 * data/yacc.c, data/glr.c: Adjust.
12104 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
12105 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
12106 as default values.
12107
12108 2005-09-16 Akim Demaille <akim@epita.fr>
12109
12110 * data/lalr1.cc (yylex_): Remove, inline its code.
12111 (yyreport_syntax_error_): Remove, replaced by...
12112 (yysyntax_error_): this which returns a string and leaves to the
12113 caller the call to the users' error function.
12114 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
12115 Move from members of the parser object...
12116 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
12117 to local variables of the parse function.
12118
12119 2005-09-16 Akim Demaille <akim@epita.fr>
12120
12121 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF

12125
12126 * data/glr.c (yyresolveValue): Add default case to pacify

12134 (b4_filename_type): Renamed back from b4_file_name_type. All uses
12135 changed.
12136 (class position): file_name -> filename (reverting). All uses changed.
12137

12139
12140 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't

12142 patch.
12143
12144 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
12145
12146 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
12147 contains obsolete information and isn't worth distributing as a
12148 separate file anyway.
12149 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
12150 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
12151 All uses of jmp_buf, setjmp, longjmp changed to use these instead.

12162 Problem reported by twlevo@xs4all.nl.
12163
12164 * doc/bison.texinfo: Don't use "filename", as per GNU coding
12165 standards. Use "file name" or "file" or "name", depending on
12166 the context.

12168 not to hack/foo.tab.c.

12188 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
12189
12190 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is

12194
12195 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.

12207 Mention Gzip version problem, and bootstrapping issues.
12208 Remove troubleshooting section, as it's somewhat obsolete.
12209
12210 * bootstrap (no_cache): New var, to accommodate different wget
12211 variants. Use it instead of '-C off'. Problem reported by
12212 twlevo@xs4all.nl.

12249 with the other templates, and to fix bogus run-on messages such
12250 as the one reported at the end of
12251 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
12252 All callers changed to avoid the newline.
12253 (yyprocessOneStack): Output two lines rather than one, to accommodate

12267 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
12268
12269 * NEWS: Version 2.0b.
12270
12271 * Makefile.am (SUBDIRS): Put examples before tests, so that
12272 "make check" doesn't finish with "All 1 tests passed".
12273
12274 * tests/regression.at (Token definitions): Don't rely on
12275 AT_PARSER_CHECK for data that contains backslashes. It currently
12276 uses 'echo', and 'echo' isn't portable if its argument contains
12277 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
12278 that the byte '\0xff' is not printable in the C locale; it is,
12279 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
12280 not printable, so use '\0x81' to test.
12281
12282 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
12283 version of GCC, since the macro is used with non-GCC compilers.
12284
12285 Fix core dump reported by Pablo De Napoli in
12286 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
12287 * tests/regression.at (Invalid inputs with {}): New test.
12288 * src/parse-gram.y (token_name): Translate type before using
12289 it as an index.
12290
12291 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
12292 the user's name space. All uses changed to __attribute__
12293 ((__unused__)).
12294 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
12295 Add __attribute__ ((__noreturn__)).
12296
12297 * etc/clcommit: Remove. We weren't using it, and it failed
12298 "make maintainer-distcheck".
12299 * Makefile.maint: Merge from coreutils.
12300 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
12301 (syntax-check-rules): Change list of rules as described below.
12302 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
12303 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
12304 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
12305 (sc_trailing_space): New rules.
12306 (sc_xalloc_h_in_src): Remove.
12307 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
12308 (sc_space_tab, sc_error_exit_success, sc_changelog):
12309 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
12310 (makefile-check, po-check, author_mark_check):
12311 (makefile_path_separator_check, copyright-check):
12312 Use grep -n, to make it easier to find violations.
12313 Use CVS_LIST and CVS_LIST_EXCEPT.
12314 (header_regexp, h_re): Remove.
12315 (dd_c): New macro.
12316 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
12317 (my-distcheck): Use more-modern GCC flags.
12318 (signatures, %.asc): Remove.
12319 (rel-files, announcement): Remove signatures.
12320 Restore old updating code, even though we don't use it, so
12321 that we're the same as coreutils.
12322 (alpha, beta, major): Depend on news-date-check.
12323 Make the upload commands.
12324
12325 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
12326 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
12327 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
12328 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
12329 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
12330 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
12331 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
12332 * tests/sets.at: Likewise.
12333
12334 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
12335 we comment out the Autoconf version number.
12336 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
12337 it's error-prone and "make maintainer-distcheck" rejects it.
12338
12339 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
12340 Indent calls to "error" to pacify "make maintainer-distcheck",
12341 when the calls are not intended to be translated.
12342 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
12343
12344 * src/Makefile.am (DEFS): Use +=, to pacify
12345 "make maintainer-distcheck".
12346 (bison_SOURCES): Add scan-skel.h.
12347 (sc_tight_scope): New rule, from coreutils.
12348
12349 * src/files.c (src_extension, header_extension):
12350 Now static, not extern.
12351 * src/getargs.c (short_options): Likewise.
12352 * src/muscle_tab.c (muscle_table): Likewise.
12353 * src/parse-gram.y (current_class, current_type, current_prec):
12354 Likewise.
12355 * src/reader.c (grammar_end, previous_rule_end): Likewise.
12356 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
12357 * src/main.c (main): Cast bindtextdomain and textdomain calls to
12358 void, to avoid warning when NLS is disabled.
12359 * src/output.c: Include scan-skel.h.
12360 (scan_skel): Remove decl, since scan-skel.h does this.
12361 (output_skeleton):
12362 Indent calls to "error" to pacify "make maintainer-distcheck".
12363 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
12364 * src/reader.h (gram_end, gram_lineno): New decls to pacify
12365 "make maintainer-distcheck".
12366 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
12367 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
12368 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
12369 (skel_lex_destroy, scan_skel): Move these decls to...
12370 * src/scan-skel.h: New file.
12371 * src/uniqstr.c (uniqstr_assert):
12372 Indent calls to "error" to pacify "make maintainer-distcheck".
12373
12374 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
12375 not @VAR@.
12376
12377 * tests/torture.at: Revamp to avoid misuse of atoi that
12378 "make maintainer-distcheck" complained about.
12379
12380 * examples/extexi (message): Don't print a message more than once,
12381 and omit line-number decoration that makes Emacs compile think
12382 that informative messages are worth worrying about.
12383
12384 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
12385
12386 * configure.ac: Update version number.
12387
12388 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
12389 accidentally.
12390 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
12391 autogenerated by the maintainer.
12392 * examples/calc++/.cvsignore: Add *.yy.
12393
12394 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
12395 * lib/bitset_stats.c (bitset_stats_init): Likewise.
12396 * lib/bitsetv.c (bitsetv_alloc): Likewise.
12397
12398 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
12399
12400 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
12401 from maintainer-distcheck about casting the argument of 'free'.
12402
12403 * NEWS: Mention recent yytname changes.
12404 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
12405
12406 * bootstrap: For translations that have not yet been upgraded to
12407 the new runtime-po domain, prime the pump by extracting the
12408 relevant strings from the obsolete translations. This code can be
12409 removed once the bison-runtime domain has been translated by each
12410 team.
12411
12412 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
12413 now that token names are already quoted.
12414
12415 Fix problem reported by Anthony Heading.
12416 * data/glr.c (YYTOKEN_TABLE): New macro.
12417 (yytname): Define if YYTOKEN_TABLE.
12418 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
12419 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
12420 (YYERROR_VERBOSE): Define the same way the other skeletons do.
12421 * src/output.c (prepare_symbols): Output token_table_flag.
12422
12423 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
12424
12425 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
12426 again if the first call fails.
12427
12428 * data/glr.c (yytnamerr): New function.
12429 (yyreportSyntaxError): Use it to dequote most string literals.
12430 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
12431 with other skeletons. All uses changed.
12432 (yytnameerr_): New function.
12433 (yyreport_syntax_error): Use it to dequote most string literals.
12434 * data/yacc.c (yytnamerr): New function.
12435 (yyerrlab): Use it to decode most string literals.
12436 * doc/bison.texinfo (Decl Summary, Calling Convention):
12437 Clarify quoting convention of yytname.
12438 * src/output.c (prepare_symbols): Quote all names. This undoes
12439 the 2005-04-17 change, which is now accomplished (mostly) via
12440 changes in the parsers as described above.
12441 * tests/regression.at (Token definitions, Web2c Actions):
12442 Undo most 2005-04-17 change here, too.
12443
12444 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
12445
12446 Fix more problems reported by twlevo@xs4all.nl.
12447 * tests/cxx-type.at: Don't pipe output of ./types through sed to
12448 remove trailing spaces. This loses the exit status of ./types,
12449 and isn't needed since ./types shouldn't be emitting trailing
12450 spaces.
12451 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
12452 as the stack isn't valid in that case.
12453
12454 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
12455 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
12456 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
12457 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
12458 is used.
12459 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
12460 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
12461 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
12462 Likewise.
12463
12464 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
12465 overly-picky compilers that reject 'char *foo = "bar";'.
12466
12467 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
12468 to FILE * parameter, not to stderr. This fixes a typo introduced
12469 in the 2005-07-12 change.
12470
12471 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
12472 warnings from GCC 4.
12473
12474 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
12475 (yyglrShiftDefer, yysplitStack):
12476 Remove unused parameters b4_pure_formals. All uses changed.
12477 (yyglrShift): Remove unused parameters b4_user_formals.
12478 All uses changed.
12479 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
12480
12481 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
12482
12483 Destructor cleanups and regularization among the three skeletons.
12484 * NEWS: Document the behavior changes.
12485 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
12486 stack before failing, as the cleanup code will do it for us now.
12487 * data/lalr1.cc (yyerrlab): Likewise.
12488 * data/glr.c (yyparse): Pop everything off the stack before
12489 freeing it, so that destructors get called properly.
12490 * data/lalr1.cc (yyreturn): Likewise.
12491 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
12492 This is more consistent.
12493 * doc/bison.texinfo (Destructor Decl): Mention more reasons
12494 why destructors might be called. 1.875 -> 2.1.
12495 (Destructor Decl, Decl Summary, Table of Symbols):
12496 Some English-language cleanups for %destructor.
12497 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12498 Add output line for destructor of start symbol.
12499 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
12500 because of that same extra output line.
12501
12502 * NEWS: Document minor wording changes in diagnostics of
12503 Bison-generated parsers.
12504 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
12505 Remove unused formals. All uses changed.
12506 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
12507 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
12508 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
12509 Rename yyoverflowab to yyexhaustedlab.
12510 When memory exhaustion occurs during syntax-error reporting,
12511 report it separately rather than in a single diagnostic; this
12512 eases translation.
12513 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
12514 (Memory Exhausted): Renamed from Parser Stack Overflow.
12515 Revamp wording slightly to prefer "memory exhaustion".
12516 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
12517
12518 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
12519
12520 Add i18n support to the GLR skeleton. Partially fix the C++
12521 skeleton; a C++ expert needs to finish this. Remove debugging
12522 msgids; there's little point to having them translated, since they
12523 can be understood only by someone who can read the
12524 (English-language) source code.
12525
12526 Generate runtime-po/bison-runtime.pot automatically, so that we
12527 don't have to worry about garbage getting in that file. We'll
12528 make sure after the next official release that old msgids don't
12529 get lost. See
12530 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
12531
12532 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
12533 Now auto-generated.
12534 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
12535 Fix typos in explanations of the runtime file.
12536 * bootstrap: Change gettext keyword from YYI18N to YY_.
12537 Use standard Makefile.in.in in runtime-po, since we'll arrange
12538 for backward-compatible bison-runtime.po files in a different way.
12539 * data/glr.c (YY_): New macro, from yacc.c.
12540 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
12541 Translate messages intended for users.
12542 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
12543 the wording in the other skeletons. We don't know that the memory
12544 is virtual.
12545 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
12546 Use same method that yacc.c uses.
12547 Don't translate debugging messages.
12548 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
12549 it doesn't work (yet), and requires C++ expertise to fix.
12550 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
12551 Move defn to a more logical place, to be consistent with other
12552 skeletons.
12553 Don't translate debugging messages.
12554 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
12555 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
12556 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
12557 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
12558
12559 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
12560 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
12561 void, not int.
12562 * tests/glr-regression.at (Badly Collapsed GLR States):
12563 Likewise.
12564 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
12565 yylex should return 0 at EOF rather than aborting.
12566
12567 Improve tests for stack overflow in GLR parser.
12568 Problem reported by twlevo@xs4all.nl.
12569 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
12570 All uses removed.
12571 (yyStackOverflow): Just longjmp, but with value 2 so that caller
12572 can handle the problem.
12573 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
12574 (yyparse): New local variable yyresult to record the result.
12575 Use result of setjmp to set it, rather than storing itinto
12576 struct.
12577 (yyDone): Remove label.
12578 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
12579 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
12580 if YYABORT is used).
12581 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
12582 yyparse status; put status > 1 into diagnostic.
12583 Check that status==2 works.
12584 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
12585 Use exit status 3 for failure to open (which shouldn't happen).
12586
12587 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
12588
12589 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
12590 1 on syntax error; just let yyparse do its thing.
12591 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
12592 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
12593 (Exploding the Stack Size with Alloca):
12594 (Exploding the Stack Size with Malloc):
12595 Expect exit status 2, not 1, since the parser is supposed to blow
12596 its stack. Problem reported by twlevo@xs4all.nl.
12597
12598 * data/glr.c (yyparse): Don't assume that the initial calls
12599 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
12600 Print a stack-overflow message and fail instead.
12601 Initialize the line-number information before creating the stack,
12602 so that the stack-overflow message can report line zero safely.
12603
12604 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
12605
12606 Fix problems reported by twlevo@xs4all.nl.
12607 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
12608 (yyuserMerge): Provide a default case if b4_mergers is empty.
12609 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
12610 * tests/glr-regression.at
12611 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
12612 Add casts to pacify C++ compilers.
12613 * tests/glr-regression.at (Improper merging of GLR delayed action
12614 sets): Declare yylex before using it.
12615 * tests/Makefile.am (maintainer-check-g++): Fix a stray
12616 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
12617 test for valgrind; valgrind is independent of g++.
12618 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
12619 for compatibility with POSIX 1003.1-2001 (if running coreutils).
12620 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
12621 Use a destructor, so that we can expand the stack. Change
12622 YYSTYPE to char * so that we can free it. Cast result of malloc.
12623
12624 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12625
12626 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
12627 a valgrind failure. Problem reported by twlevo@xs4all.nl.
12628
12629 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
12630
12631 * PACKAGING: New file, suggested by Bruno Haible and taken from
12632 similar wording in gettext's PACKAGING file.
12633 * NEWS: Mention PACKAGING.
12634 * Makefile.am (EXTRA_DIST): Add PACKAGING.
12635
12636 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
12637
12638 * NEWS: Document recent i18n improvements.
12639 * bootstrap: Get runtime translations into runtime-po.
12640 Create runtime-po files automatically, if possible.
12641 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
12642 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
12643 does not infringe on the user's name space.
12644 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
12645 * doc/bison.texinfo (Internationalization): Revamp the English
12646 and Texinfo syntax a bit, to try to make it clearer.
12647 (Bison Options, Option Cross Key): Mention --print-localedir.
12648 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
12649 YYENABLE_NLS. Quote a bit more.
12650 * runtime-po/.cvsignore: New file.
12651 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
12652 * runtime-po/Rules-quot: Remove; now created by bootstrap.
12653 * runtime-po/quot.sed: Likewise.
12654 * runtime-po/boldquot.sed: Likewise.
12655 * runtime-po/en@quot.header: Likewise.
12656 * runtime-po/en@boldquot.header: Likewise.
12657 * runtime-po/insert-header.sin: Likewise.
12658 * runtime-po/remove-potcdate.sin: Likewise.
12659 * runtime-po/Makevars: Likewise.
12660 * runtime-po/LINGUAS: Likewise.
12661 * runtime-po/de.po: Likewise; we will rely on the translation project
12662 to maintain this, so "bootstrap" should get it.
12663 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
12664 its value.
12665 * src/main.c (main): Bind the bison-runtime domain, too.
12666
12667 2005-07-12 Bruno Haible <bruno@clisp.org>
12668
12669 * data/yacc.c: Include <libintl.h> when NLS is enabled.
12670 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
12671 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
12672 * runtime-po: New directory.
12673 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
12674 $(DOMAIN).pot-update rule, so that old messages are never dropped.
12675 * runtime-po/Rules-quot: New file, copied from po/.
12676 * runtime-po/quot.sed: Likewise.
12677 * runtime-po/boldquot.sed: Likewise.

12685 * runtime-po/bison-runtime.pot: New file.
12686 * runtime-po/de.po: New file.
12687 * m4/bison.m4: New file.
12688 * Makefile.am (SUBDIRS): Add runtime-po.
12689 (aclocaldir, aclocal_DATA): New variables.
12690 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
12691 Define aclocaldir.
12692 * src/getargs.c (usage): Document --print-localedir option.
12693 (PRINT_LOCALEDIR_OPTION): New enum item.
12694 (long_options): Add --print-localedir option.
12695 (getargs): Handle --print-localedir option.
12696 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
12697 (Internationalization): New section.
12698
12699 2005-07-12 Akim Demaille <akim@epita.fr>
12700
12701 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
12702 for consistency with the rest of the code.
12703 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
12704 Add separators.
12705
12706 2005-07-12 Akim Demaille <akim@epita.fr>
12707
12708 * src/parse-gram.y: Use %printer instead of YYPRINT.
12709
12710 2005-07-12 Akim Demaille <akim@epita.fr>
12711
12712 * src/symtab.h, src/symtab.c (symbol_print): New.
12713 * src/symlist.h, src/symlist.c (symbol_list_print): New.
12714 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
12715
12716 2005-07-12 Akim Demaille <akim@epita.fr>
12717
12718 * data/glr.c (b4_syncline): Fix (swap) the definitions of
12719 b4_at_dollar and b4_dollar_dollar.
12720
12721 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
12722
12723 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
12724 and Pennello's paper.
12725
12726 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
12727
12728 * data/yacc.c (yyparse): Undo previous patch. Instead,
12729 set yylsp[0] and yyvsp[0] only if the initial action
12730 sets yylloc and yylval, respectively.
12731
12732 * data/yacc.c (yyparse): In the initial action, set
12733 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
12734 This avoids the use of undefined variables if the initial
12735 action does not set yylloc and/or yylval.
12736
12737 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12738
12739 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
12740 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
12741 Remove from CVS. These files are automatically generated.
12742 * examples/extexi: Clarify that this file is now part of Bison,
12743 not GNU M4, and that it works with any POSIX-compatible Awk.
12744 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
12745 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
12746 so that we also get calc++-parser.yy. Geneate it.
12747 Use $(AWK), not gawk, since any conforming Awk will do.
12748 Put comment before action, since older 'make' can't handle comment
12749 in action.
12750 $(BUILT_SOURCES): List all built sources, not just some of them.
12751 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
12752 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
12753 $($(calc_sources_generated)): Remove unnecessary test for existence
12754 of target. (This had a shell syntax error anyway; a stray "x".)
12755 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
12756 calc++-parser.yy.
12757 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
12758
12759 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
12760 implied by the other modules.
12761
12762 2005-07-06 Akim Demaille <akim@epita.fr>
12763
12764 Bind examples/calc++ to the package.
12765 * examples/calc++/Makefile: Remove, replaced by...
12766 * examples/calc++/Makefile.am: ... this new file.
12767 * examples/calc++/test: Remove input.
12768 * examples/calc++/compile: Remove.
12769 * examples/Makefile.am: New.
12770 * configure.ac, Makefile.am: Adjust.
12771 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
12772
12773 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
12774
12775 * data/glr.c (yyFail): Drastically simplify; since the format argument
12776 never had any % directives, we can simply pass it to yyerror.
12777 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
12778 be modified later, as that is the usual style in glr.c.
12779 Problems reported by Paul Hilfinger.
12780
12781 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
12782 and size overflow errors.
12783 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
12784 in case the user prolog sets feature-test macros like _GNU_SOURCE.
12785 (YYSIZEMAX): New macro.
12786 (yystpcpy): New function, taken from yacc.c.
12787 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
12788 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
12789 so that we don't have to maintain their signatures.
12790 (yyFail): Check for buffer overflow, by using vsnprintf rather
12791 than vsprintf. Allocate a bigger buffer if possible.
12792 Report an error if buffer allocation fails.
12793 (yyStackOverflow): New function.
12794 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
12795 the initialization was successful. It might fail if storage was
12796 exhausted.
12797 (yyexpandGLRStack): Add more checks for storage allocation failure.
12798 Use yyStackOverflow to report failures.
12799 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
12800 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
12801 Don't assume stack number fits in int.
12802 (yysplitStack): Check for storage allocation failure.
12803 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
12804 can print diagnostics on storage allocation failure. All callers
12805 changed.
12806 (yyresolveValue): Use yybool for boolean.
12807 (yyreportSyntaxError): Check for size-calculation overflow.
12808 This code is taken from yacc.c.
12809 (yyparse): Check for storage allocation errors when allocating
12810 the initial stack.
12811
12812 2005-07-05 Akim Demaille <akim@epita.fr>
12813
12814 Extract calc++ from the documentation.
12815 * doc/bison.texinfo (Calc++): Add the extraction marks.
12816 * examples/extexi: New, from the aborted GNU Programming 2E.
12817 Separate the different paragraph of a file with empty lines.
12818 * examples/Makefile: Use it to extract the whole calc++ example.
12819
12820 2005-06-24 Akim Demaille <akim@epita.fr>
12821
12822 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
12823 class typedefs.
12824
12825 2005-06-22 Akim Demaille <akim@epita.fr>
12826
12827 * doc/bison.texinfo (C++ Language Interface): First stab.
12828 (C++ Parsers): Remove.
12829
12830 2005-06-22 Akim Demaille <akim@epita.fr>
12831
12832 * data/lalr1.cc (yylex_): Honor %lex-param.
12833
12834 2005-06-22 Akim Demaille <akim@epita.fr>
12835
12836 Start a set of simple examples.
12837 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
12838 * examples/calc++/calc++-driver.hh,
12839 * examples/calc++/calc++-parser.yy,
12840 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
12841 * examples/calc++/compile, examples/calc++/test: New.
12842
12843 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
12844
12845 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
12846 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
12847 which stems from the 2005-05-27 patch.
12848
12849 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
12850
12851 * data/glr.c: Modify treatment of unused parameters to permit use
12852 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
12853
12854 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
12855
12856 Fix infringement on user name space reported by Janos Zoltan Szabo.
12857 * data/yacc.c (yyparse): strlen -> yystrlen.
12858
12859 2005-05-30 Akim Demaille <akim@epita.fr>
12860
12861 * data/lalr1.cc (_): New.
12862 Translate the various messages.
12863
12864 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
12865
12866 Fix infringement on user name space reported by Bruno Haible.
12867 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
12868 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
12869 the user's name space.
12870 (alloca): Include <stdlib.h> to get it, if it's not built in.
12871 (YYMALLOC, YYFREE): Define only if needed.
12872 (malloc, free): Declare, but only if needed, as this infringes on
12873 the user name space.
12874
12875 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12876
12877 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
12878 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
12879 with %d format.
12880 * lib/ebitset.c (min, max): Undef before defining.
12881 * lib/vbitset.c (min, max): Likewise.
12882 * lib/subpipe.c (create_subpipe): Save local variables in case
12883 vfork clobbers them.
12884
12885 2005-05-24 Bruno Haible <bruno@clisp.org>
12886
12887 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
12888 error message syntax used by gcc-4.0.
12889
12890 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
12891
12892 * README: Mention m4 1.4.3. Remove obsolete advice about
12893 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
12894
12895 * bootstrap: Remove workaround for problem I encountered with
12896 gettext 0.14.1; it seems to be fixed now.
12897
12898 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
12899
12900 * NEWS: Version 2.0a.
12901
12902 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
12903 the previous change.
12904
12905 Various maintainer cleanups.
12906 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
12907 conftest*, for benefit of CVS commands run at the same time as
12908 "configure". Add build-aux, since "bootstrap" now creates it and
12909 its subfiles.
12910 * Makefile.cfg (move_if_change): Remove.
12911 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
12912 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
12913 (po_repo, do-po-update, po-update, wget_files, get-targets):
12914 (config.guess-url_prefix, config.sub-url_prefix):
12915 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
12916 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
12917 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
12918 Remove.
12919 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
12920 this is now the recommended name.
12921 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
12922 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
12923 ylwrap. These files now go into build-aux.
12924 * config/move-if-change: Remove.
12925 * config/prev-version.txt: Bump from 1.75 to 2.0.
12926
12927 * bootstrap: Add stdio-safer, unistd-safer modules.
12928 Remove m4/glibc2.m4 (introduced by latest gnulib, but
12929 we don't need it).
12930 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
12931 fopen-safer.c, stdio-safer.h, unistd-safer.h.
12932 * lib/subpipe.c: Include "unistd-safer.h".
12933 (create_subpipe): Make sure all the newly-created
12934 file descriptors are > 2, so that diagnostics don't
12935 get sent down them (which might cause Bison to hang, in theory).
12936 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
12937 * src/files.c (xfopen): Use fopen_safer, not fopen.
12938
12939 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
12940 yesterday's yacc.c fix.
12941
12942 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
12943
12944 * data/glr.c, data/lalr1.cc: Update copyright date.
12945
12946 Fix a destructor bug reported by Wolfgang Spraul in
12947 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
12948 * data/yacc.c (yyabortlab): Don't call destructor, and
12949 don't set yychar to EMPTY.
12950 (yyoverflowlab): Don't call destructor.
12951 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
12952 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
12953 since we no longer output the message "discarding lookahead token
12954 end of input ()".
12955
12956 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12957
12958 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
12959 fix a small glitch in debugging output.
12960 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
12961 after YY_SYMBOL_PRINT where needed.
12962
12963 (struct yyGLRState): Add some comments.
12964 (struct yySemanticOption): Add some comments.
12965 (union yyGLRStackItem): Add comment.
12966
12967 (yymergeOptionSets): Correct this to properly perform the union,
12968 avoiding infinite reported by Michael Rosien.
12969 Update comment.
12970
12971 * tests/glr-regression.at: Add test for GLR merging error reported
12972 by M. Rosien.
12973

13016
13017 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13018
13019 * tests/actions.at: Test that stack overflow invokes destructors.
13020 From Marcus Holland-Moritz.
13021 * data/yacc.c (yyerrlab): Move the code that destroys the stack
13022 from here....
13023 (yyreturn): to here. That way, destructors are called properly
13024 even if the stack overflows, or the user calls YYACCEPT or
13025 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
13026 (yyoverflowlab): Destroy the lookahead.
13027
13028 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
13029
13030 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
13031
13032 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
13033
13034 * NEWS: Bison-generated C parsers no longer quote literal strings
13035 associated with tokens.
13036 * src/output.c (prepare_symbols): Don't escape strings,
13037 since users don't want to see C escapes.
13038 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
13039 in diagnostics.
13040 * tests/input.at (Torturing the Scanner): Likewise.
13041 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
13042
13043 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
13044
13045 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
13046 the data size is known to be too small and we can't increase it.
13047 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
13048
13049 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
13050
13051 * src/parse-gram.y: Include quotearg.h.
13052 (string_as_id): Quote $1 before using it as a key, since the
13053 lexer no longer quotes it for us.
13054 (string_content): Don't strip quotes, since lexer no longer
13055 quotes it for us.
13056 * src/scan-gram.l: Include quotearg.h.
13057 ("\""): Omit quote.
13058 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
13059 a key, since the rest of the lexer doesn't quote it.
13060 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
13061 * tests/regression.at (Token definitions): Check for backslashes
13062 in token strings.
13063
13064 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
13065 (YYSIZE_T): Define to unsigned long int when using an older compiler.
13066 (yyparse): Revamp code to generate long syntax error message, to
13067 make it easier to translate, and to avoid problems with arithmetic
13068 overflow. Change "virtual memory" to "memory" in diagnostic, since
13069 we don't know whether the memory is virtual.
13070
13071 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13072
13073 * NEWS: Bison-generated C parsers now use the _ macro to
13074 translate strings.
13075 * data/yacc.c (_) [!defined _]: New macro.
13076 All English strings wrapped inside this macro.
13077 * doc/bison.texinfo (Bison Parser): Document _.
13078 * po/POTFILES.in: Include src/parse-gram.c, since it now
13079 includes translateable strings that parse-gram.y doesn't.
13080
13081 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
13082
13083 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
13084 reverting the 2004-10-11 change to this function.
13085 (symbol_check_alias_consistency): Don't call symbol_type_set
13086 if the type name is already correct.
13087 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
13088
13089 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
13090
13091 * tests/regression.at (Token definitions): Don't use a token named
13092 c, as that generates a "#define c ..." that runs afoul of buggy
13093 stdlib.h that uses the identifier c as a member of struct
13094 drand48_data. Problem reported by Horst Wente.
13095
13096 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
13097
13098 * bootstrap: Change translation URL from
13099 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
13100 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
13101 redirection glitches. Problem reported by twlevo@xs4all.nl.
13102
13103 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
13104
13105 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
13106 after operands; POSIX says this isn't portable for the c99 command.
13107
13108 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
13109
13110 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
13111 immediately if a data overrun has occurred; this may help us track
13112 down what may be a spurious failure on MacOS.
13113
13114 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
13115
13116 Respond to problems reported by twlevo@xs4all.nl.
13117
13118 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
13119
13120 * src/vcg.h: Comment fix.
13121 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
13122 (G_CMAX): Change to -1 instead of INT_MAX.
13123
13124 * data/yacc.c (yyparse): Omit spaces before #line.
13125
13126 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
13127
13128 * src/tables.c (state_number_to_vector_number): Put it inside an
13129 "#if 0", since it's not currently used. Problem reported by
13130 Roland McGrath.
13131
13132 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
13133
13134 * src/output.c (escaped_output): Renamed from
13135 escaped_file_name_output, since we now use it for symbol tags as
13136 well. All uses changed.
13137 (symbol_destructors_output, symbol_printers_output):
13138 Escape symbol tags too.
13139 Problem reported by Matyas Forstner in
13140 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
13141
13142 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
13143 not needed.
13144 * src/output.c (user_actions_output, token_definitions_output,
13145 symbol_destructors_output, symbol_printers_output): Likewise.
13146 * src/reader.c (prologue_augment): Likewise.
13147 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
13148
13149 * src/vcg.c (output_edge): Don't quote linestyle arg.
13150 Problem reported by twlevo@xs4all.nl.
13151
13152 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
13153
13154 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
13155 example, reported by Derek M Jones. Also, make the example even
13156 more outrageous, to better illustrate how bad the problem is.
13157
13158 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
13159
13160 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
13161 putsym. Typo reported by Sebastian Piping.
13162
13163 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13164
13165 * doc/bison.texinfo (Language and Grammar): some -> same
13166 (Epilogue): int he -> in the
13167 Typos reported by Sebastian Piping via Justin Pence.
13168
13169 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13170
13171 * tests/glr-regression.at (Improper handling of embedded actions
13172 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
13173 embedded actions and $-N in GLR parsers", work around an Autoconf bug
13174 with dollar signs in test names.
13175 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
13176 for a similar reason.
13177
13178 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13179
13180 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
13181 wants to redefine G_VIEW.
13182
13183 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
13184
13185 * src/vcg.c (get_view_str): Remove case for normal_view.

13190 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
13191 Problem reported by twlevo@xs4all.nl.
13192
13193 * doc/bison.texinfo: Change @dircategory from "GNU programming
13194 tools" to "Software development". Requested by Richard Stallman
13195 via Karl Berry.
13196
13197 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
13198
13199 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
13200 Problem reported by twlevo@xs4all.nl.
13201
13202 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
13203
13204 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
13205 keyword; it's not needed with modern compilers, and it doesn't
13206 affect correctness with older compilers. Suggested by
13207 twlevo@xs4all.nl.
13208
13209 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
13210
13211 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
13212 gcc -Wswitch-default.
13213 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
13214 * data/yacc.c (yyparse): Likewise.
13215
13216 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
13217
13218 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
13219 already. Let config.h define any nonstandard values.
13220
13221 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
13222
13223 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
13224 for the benefit of slower hosts. Problem reported by
13225 Nelson H. F. Beebe.
13226
13227 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
13228
13229 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
13230 being defined and not used.
13231 * data/lalr1.cc (yyparse): Likewise.
13232 Use "if (false)" rather than "if (0)".
13233
13234 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
13235
13236 * TODO: Mention that we should allow NUL bytes in tokens.
13237
13238 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
13239
13240 * src/scan-skel.l (<<EOF>>): Don't close standard output.
13241 Problem reported by Hans Aberg.
13242
13243 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
13244
13245 * src/getargs.c (version): Happy new year; update overall
13246 program copyright date from 2004 to 2005.
13247
13248 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
13249 Problem reported by Hans Aberg.
13250 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
13251 (Output file names.): Add a test for the case when standard output
13252 is closed.
13253
13254 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
13255
13256 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
13257 to fix an oversight in the Bison 2.0 manual.
13258
13259 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
13260
13261 * NEWS: Version 2.0. Reformat the existing news items since
13262 1.875, so that related items are grouped together.
13263 * configure.ac (AC_INIT): Bump version to 2.0.
13264 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
13265
13266 * tests/torture.at (Exploding the Stack Size with Alloca): Set
13267 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
13268 otherwise, we're not testing alloca. Unfortunately there's no
13269 simple way to consult HAVE_ALLOCA here.
13270
13271 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
13272 for yymsg, too.
13273
13274 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
13275 hand. This avoids a warning about comparing int to size_t when
13276 GCC warnings are enabled.
13277
13278 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
13279
13280 * NEWS: Bison-generated parsers no longer default to using the
13281 alloca function (when available) to extend the parser stack, due
13282 to widespread problems in unchecked stack-overflow detection.
13283 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
13284 responsibility to set it to a positive value. This lets the user
13285 specify a value that is not a preprocessor constant.
13286 * data/yacc.c (YYMAXDEPTH): Likewise.
13287 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
13288 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
13289 to be a compile-time constant. However, explain the constraints on it.
13290 Also, explain the constraints on YYINITDEPTH.
13291 (Table of Symbols): Explain that alloca is no longer the default.
13292 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
13293 to 1.
13294
13295 * doc/bison.texinfo (Location Default Action): Mention that n must
13296 be zero when k is zero. Suggested by Frank Heckenbach.
13297
13298 2004-12-22 Akim Demaille <akim@epita.fr>
13299
13300 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
13301 (parser::state_type, parser::semantic_type, parser::location_type):
13302 Private, not public.
13303 (parser::parse): Return ints, not bool.
13304 Returning a bool introduces a problem: 0 corresponds to false, and
13305 it seems weird to return false on success. Returning true changes
13306 the conventions for yyparse.
13307 Alternatively we could return void and send an exception.
13308 There is no clear consensus (yet?).
13309 (state_stack, semantic_stack, location_stack): Rename as...
13310 (state_stack_type, semantic_stack_type, location_stack_type): these.
13311 Private, not public.
13312 * tests/c++.at: New.
13313 * tests/testsuite.at, tests/Makefile.am: Adjust.
13314
13315 2004-12-21 Akim Demaille <akim@epita.fr>
13316
13317 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
13318
13319 2004-12-21 Akim Demaille <akim@epita.fr>
13320
13321 Don't impose std::string for filenames.
13322
13323 * data/lalr1.cc (b4_filename_type): New.
13324 (position::filename): Use it.
13325 (parser.hh): Move the inclusion of stack.hh and location.hh below
13326 the user code, so that needed headers for the filename type can be
13327 included first.
13328 Forward declare them before the user code.
13329 * tests/Makefile.am (check-local, installcheck-local): Pass
13330 TESTSUITEFLAGS to the TESTSUITE.
13331
13332 2004-12-20 Akim Demaille <akim@epita.fr>
13333
13334 Use more STL like names: my_class instead of MyClass.
13335
13336 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
13337 (SemanticStack, SemanticType, StateStack, StateType)
13338 (TokenNumberType, Stack, Slice, Traits, Parser::location)
13339 (Parser::value): Rename as...
13340 (location_stack, location_type, rhs_number_type, semantic_stack)
13341 (semantic_type, state_stack, state_type, token_number_type, stack)
13342 (slice, traits, parser::yylloc, parser::yylval): these.
13343
13344 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
13345
13346 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
13347
13348 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
13349 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
13350
13351 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
13352
13353 Remove uses of 'short int' and 'unsigned short int'. This raises
13354 some arbitrary limits. It uses more memory but nowadays that's
13355 not much of an issue.
13356
13357 This change does not affect the generated parsers; that's a different
13358 task, as some users will want to conserve memory there.
13359
13360 Ideally we should use size_t to represent all object counts, and
13361 something like ptrdiff_t to represent signed differences of object
13362 counts; but that will require more code-cleanup than I have the
13363 time to do right now.
13364
13365 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
13366 Use size_t, not int or short int, to count objects.
13367 * src/closure.c (nritemset, closure): Likewise.
13368 * src/closure.h (nritemset, closure): Likewise.
13369 * src/nullable.c (nullable_compute): Likewise.
13370 * src/print.c (print_core): Likewise.

13374 * src/tables.c (default_goto, goto_actions): Likewise.
13375
13376 * src/gram.h (rule_number, rule): Use int, not short int.
13377 * src/output.c (prepare_rules): Likewise.
13378 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
13379 errs, reductions): Likewise.
13380 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
13381 Likewise.
13382 * src/tables.c (vector_number, tally, action_number,
13383 ACTION_NUMBER_MINIMUM): Likewise.
13384 * src/output.c (muscle_insert_short_int_table): Remove.
13385
13386 2004-12-17 Akim Demaille <akim@epita.fr>
13387
13388 * data/lalr1.cc: Extensive Doxygenation.
13389 (error_): Rename as...
13390 (error): this, since it is visible to the user.
13391 Adjust callers.
13392 (Parser::message): Now an automatic variable from...
13393 (Parser::yyreport_syntax_error_): here.
13394 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
13395 Parser::error.
13396 * tests/input.at: Escape $.
13397
13398 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
13399
13400 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
13401 Parenthesize rhs to avoid obscure problems with mistakes like
13402 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
13403 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
13404 b4_rhs_location): Likewise.
13405 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
13406 b4_rhs_location): Likewise.
13407
13408 2004-12-16 Akim Demaille <akim@epita.fr>
13409
13410 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
13411 yacc.c: be sure to stay within yycheck_.
13412 * tests/actions.at: Re-enable C++ tests.
13413
13414 2004-12-16 Akim Demaille <akim@epita.fr>
13415
13416 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
13417 real.
13418
13419 2004-12-16 Akim Demaille <akim@epita.fr>
13420
13421 Use #define to handle the %name-prefix.
13422
13423 * data/glr.c, data/yacc.c: Comment changes.
13424 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
13425 so that one can refer to yylex in the parser file, and have it
13426 renamed, as is the case with other skeletons.
13427
13428 2004-12-16 Akim Demaille <akim@epita.fr>
13429
13430 Move lalr1.cc internals into yy*.

13450 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
13451
13452 Fix some problems reported by twlevo at xs4all.
13453 * src/symtab.c (symbol_new): Report an error if the input grammar
13454 contains too many symbols. This is better than calling abort() later.
13455 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
13456 (struct node, struct graph):
13457 Rename member expand to stretch. All uses changed.
13458 (struct graph): Remove member layoutalgorithm. All uses removed.
13459 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
13460 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
13461 All uses changed.
13462 (N_STRETCH): Rename from N_EXPAND. All uses changed.
13463
13464 2004-12-15 Akim Demaille <akim@epita.fr>
13465
13466 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
13467 Add more Doxygen comments.
13468 (symprint_, stack_print_, reduce_print_, destruct_, pop)
13469 (report_syntax_error_, translate_): Rename as...
13470 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
13471 (yypop_, yyreport_syntax_error_, yytranslate_): this.
13472
13473 2004-12-15 Akim Demaille <akim@epita.fr>
13474
13475 * data/lalr1.cc (lex_): Rename as...
13476 (yylex_): this.
13477 Move the trace here.
13478 Take the %name-prefix into account.
13479 Reported by Alexandre Duret-Lutz.
13480
13481 2004-12-15 Akim Demaille <akim@epita.fr>
13482
13483 Simplify the C++ parser constructor.
13484
13485 * data/lalr1.cc (debug_): Rename as...
13486 (yydebug_): so that the parser's internals are always in the yy*
13487 pseudo namespace.
13488 Adjust uses.
13489 (b4_parse_param_decl): Remove the leading comma as it is now only
13490 called as unique argument list.
13491 (Parser::Parser): Remove the constructor accepting a location and
13492 an initial debugging level.
13493 Remove from the other ctor the argument for the debugging level.
13494 (debug_level_type, debug_level, set_debug_level): New.
13495
13496 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
13497 constructor calls.
13498
13499 2004-12-15 Akim Demaille <akim@epita.fr>
13500
13501 Remove b4_root related material: failure experiment
13502 (which goal was to allow to derive from a class).
13503
13504 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
13505 definitions and uses.
13506
13507 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
13508
13509 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
13510 not 2, since it's not portable to subtract 1 from the start of an
13511 array. The new item 0 is never set or used. All uses changed.
13512
13513 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
13514 the default definition of YYLLOC_DEFAULT. Problem reported
13515 by Frank Heckenbach.
13516
13517 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
13518
13519 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
13520 the normal case and one for the error case. Just use the
13521 first one uniformly. Problem reported by Frank Heckenbach.
13522 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
13523 use exactly the same macro in both places.
13524 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
13525 so that the normal-case YYRHSLOC works for the error case too.
13526 All uses changed.
13527 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
13528 (YYLLOC_DEFAULT): Use the same macro as glr.c.
13529 * doc/bison.texinfo (Location Default Action): Don't claim that
13530 we have an array of locations. Use the same macro for both glr
13531 and lalr parsers. Mention YYRHSLOC. Mention what happens when
13532 the index is 0.
13533
13534 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
13535

13544
13545 * src/scan-skel.l: Include "complain.h", for "fatal".
13546
13547 * src/relation.h (relation_print, relation_digraph):
13548 Relation sizes are of type relation_node, not size_t (this is
13549 merely a doc fix, since the two types are equivalent).
13550 (relation_transpose): Relation sizes are of type relation_node,
13551 not int.
13552 * src/relation.c: Likewise.
13553 (top, infinity): Now of type relation_node, not int.
13554 (traverse, relation_transpose): Use relation_node, not int.
13555
13556 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
13557 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
13558 (yyparse): Remove unused local introduced in 2004-10-25 patch.
13559
13560 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
13561 specifying whether the test should be skipped. Use it tp
13562 specify that the [%defines %skeleton "lalr1.cc"] tests currently
13563 fail on some hosts, and should be skipped.
13564
13565 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
13566
13567 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
13568 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
13569 unless otherwise specified below.
13570
13571 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
13572 to allocate kernel_base, kernel_items, kernel_size, since
13573 they needn't be initialized to 0.
13574 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
13575 * src/closure.c (new_closure): Likewise, for itemset.
13576 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

13579 (build_relations): Likewise for edge, states1, includes.
13580 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
13581 * src/reader.c (packgram): Likewise, for ritem, rules.
13582 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.

13589 conflict_list.
13590 (save_column): Likewise for froms[symno], tos[symno].
13591 (goto_actions): Likewise for state_count.
13592 (pack_table): Likewise for base, pos, check.
13593 (tables_generate): Likewise for width.
13594
13595 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
13596 for initial core. Just have a separate core, so we needn't worry
13597 about whether kernel_size and kernel_base are initialized.
13598
13599 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
13600 kernel_size, kernel_items): Remove unnecessary initialization.
13601 * src/conflicts.c (conflicts): Likewise.
13602 * src/derives.c (derives): Likewise.
13603 * src/muscle_tablc (muscle_insert): Likewise.
13604 * src/relation.c (relation_digraph): Likewise.
13605 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
13606 conflrow, conflict_table, conflict_list, table, check):
13607 Likewise.
13608
13609 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
13610 This is because all callers pass unsigned int.
13611 * src/closure.h (new_closure): Likewise.
13612
13613 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
13614 (build_relations): Initialize includes[i] in all cases.
13615 * src/reader.c (packgram): Always initialize rules[ruleno].prec
13616 and rules[ruleno].precsym. Initialize members in order.
13617 * src/relation.c (relation_transpose): Always initialize new_R[i]
13618 and end_R[i].
13619 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
13620
13621 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
13622 conflict_list[0] was always 0, but now it isn't initialized.
13623
13624 * src/table.c (table_grow): When conflict_table grew, the grown
13625 area wasn't cleared. Fix this.
13626
13627 * lib/.cvsignore: Add strdup.c, strdup.h.
13628 * m4/.cvsignore: Add strdup.m4.
13629
13630 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
13631
13632 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
13633 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
13634 GOTO_NUMBER_MAXIMUM, since we occasionally compute
13635 ngotos + 1 without checking for overflow.
13636 (build_relations): Use END_NODE, not -1, to denote end of edges.
13637 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
13638 build_relations): Use goto_number, not int, for goto numbers.
13639 * src/tables.c (save_column, default_goto): Likewise.
13640
13641 2004-11-23 Akim Demaille <akim@epita.fr>
13642
13643 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
13644 of #defining from yystype.
13645 Don't typedef yystype, C++ does not need it.
13646 This lets it possible to forward declare it as union.
13647
13648 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
13649
13650 * bootstrap (gnulib_modules): Add extensions.
13651 Problem reported by Jim Meyering.
13652
13653 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
13654
13655 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
13656 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
13657 src/system.h, src/tables.c: XFREE -> free, to accommodate
13658 recent change to gnulib xalloc.h.
13659 Problem reported by Jim Meyering.
13660
13661 2004-11-17 Akim Demaille <akim@epita.fr>
13662
13663 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
13664
13665 2004-11-17 Akim Demaille <akim@epita.fr>,
13666 Alexandre Duret-Lutz <adl@gnu.org>
13667
13668 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
13669 changes.
13670 (YYCDEBUG): Adjust.
13671 Use it instead of cdebug_.
13672 (Parser::debug_stream, Parser::set_debug_stream): New.
13673 (Parser::symprint_): Define cdebug_ for temporary backward
13674 compatibility.
13675 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
13676 debug_stream ().
13677
13678 2004-11-17 Akim Demaille <akim@epita.fr>
13679
13680 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
13681 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
13682 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
13683 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

13688 Problem reported by Frank Heckenbach.
13689
13690 2004-10-25 Akim Demaille <akim@epita.fr>
13691
13692 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
13693 Introduce another definition to address simple location arrays.
13694 (yyGLRStack): New member: yyerror_range.
13695 (yyrecoverSyntaxError, yyparse): Update it.
13696 (yyrecoverSyntaxError): Use it when shifting the error token to
13697 have an accurate range, equivalent to the one computed by both
13698 yacc.c and lalr1.cc.
13699 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
13700 that column numbers start at column 0, as per GNU Coding
13701 Standards, the others tests, and the doc.
13702 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
13703 Adjust to the above change (first column is 0).
13704 And adjust the location of the "<error>", now covering the whole
13705 line.
13706
13707 2004-10-22 Akim Demaille <akim@epita.fr>
13708 and Paul Eggert <eggert@cs.ucla.edu>
13709
13710 Remove some arbitrary limits on goto numbers and relations.
13711 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
13712 initial values, since they're never used.
13713 (set_goto_map): ngotos is now unsigned, so test for overflow
13714 by seeing whether it wraps around to zero.
13715 * src/lalr.h (goto_number): Now size_t, not short int.
13716 (GOTO_NUMBER_MAXIMUM): Remove.
13717 * src/relation.c (relation_print, traverse, relation_transpose):
13718 Check for END_NODE rather than looking at sign.
13719 * src/relation.h (END_NODE): New macro.
13720 (relation_node): Now size_t, not short int.
13721
13722 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
13723
13724 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
13725 keyword, not an identifier. Problem reported by Baron Schwartz in
13726 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
13727
13728 2004-10-11 Akim Demaille <akim@epita.fr>
13729
13730 * src/symtab.c (symbol_check_alias_consistency): Also check
13731 type names, destructors, and printers.
13732 Reported by Alexandre Duret-Lutz.
13733 Recode the handling of associativity and precedence in terms
13734 of symbol_precedence_set.
13735 Accept no redeclaration at all, not even equal to the previous
13736 value.
13737 (redeclaration): New.
13738 Use it to factor redeclaration complaints.
13739 (symbol_make_alias): Don't set the type of the alias, let
13740 symbol_check_alias_consistency do it as for other features.
13741 * src/symtab.h (symbol): Add new member prec_location, and
13742 type_location.
13743 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
13744 * tests/input.at (Incompatible Aliases): New.
13745
13746 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
13747
13748 .cvsignore fixes to accommodate gnulib changes,
13749 and the practice of naming build directories "_build".
13750 * .cvsignore: Add "_*". Sort.
13751 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
13752 * m4/.cvsignore: Add "*_gl.m4".
13753
13754 2004-10-06 Akim Demaille <akim@epita.fr>
13755
13756 * src/parse-gram.y (add_param): Fix the truncation of trailing
13757 spaces.
13758
13759 2004-10-05 Akim Demaille <akim@epita.fr>
13760
13761 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
13762 whether the reducion was empty or not. This leaves room to
13763 improve the use of YYLLOC_DEFAULT in such a case.
13764 lalr1.cc is still experimental, so changing this is acceptable.
13765 And finally, there are probably not many users who changed the
13766 handling of locations in GLR, so changing is admissible too.
13767
13768 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
13769 empty reduction, set @$ to an empty location ending the previously
13770 stacked symbol.
13771 Adjust uses to make sure the code is triggered on empty
13772 reductions.
13773 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
13774 expected output: empty reductions have empty locations.
13775
13776 2004-09-29 Akim Demaille <akim@epita.fr>
13777
13778 * data/lalr1.cc: Move towards a more standard C++ coding style
13779 for templates: Class < T > -> Class<T>.
13780
13781 2004-09-29 Akim Demaille <akim@epita.fr>
13782
13783 * data/lalr1.cc: Reinstall the former ctor, for sake of
13784 compatibility, but warn it will be removed.
13785 Move towards a more standard C++ coding style (i.e., type *var ->
13786 type* var).
13787
13788 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
13789
13790 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
13791 since it's less likely to work if NULs are involved in the future.
13792
13793 2004-09-27 Akim Demaille <akim@epita.fr>
13794
13795 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
13796
13797 2004-09-27 Akim Demaille <akim@epita.fr>
13798
13799 * data/lalr1.cc (b4_parse_param_decl_1): New.
13800 (b4_parse_param_decl): Use it to have different names between attribute
13801 and argument names.
13802 (b4_cc_constructor_call): Likewise.
13803
13804 2004-09-24 Akim Demaille <akim@epita.fr>
13805
13806 * src/parse-gram.y (add_param): Strip the leading and trailing
13807 blanks from a formal argument declaration.
13808 (YY_LOCATION_PRINT): New.
13809
13810 2004-09-24 Akim Demaille <akim@epita.fr>
13811
13812 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
13813 after the location.
13814
13815 2004-09-24 Akim Demaille <akim@epita.fr>
13816
13817 * doc/bison.texinfo (Table of Symbols): Sort.
13818
13819 2004-09-21 Akim Demaille <akim@epita.fr>
13820
13821 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
13822 the useless parentheses.
13823 Suggested by Paul Eggert.
13824
13825 2004-09-20 Akim Demaille <akim@epita.fr>
13826
13827 Let the initial-action act on the look-ahead, and use it for the
13828 "initial push" (corresponding to an hypothetical beginning-of-file).
13829 And let lalr1.cc honor %initial-action.
13830
13831 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
13832 example.
13833 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
13834 (Parser::Parser): Remove the ctor that used to initialize it.
13835 (Parser::parse): Like in the other skeletons, issue the "starting
13836 parse" message before any action.
13837 Honor %initial-action.
13838 Initialize the stacks with the lookahead.
13839 * data/yacc.c: Let $$ and @$ in %initial-action designate the
13840 look-ahead.
13841 Push them in the stacks.
13842 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
13843
13844 2004-09-20 Akim Demaille <akim@epita.fr>
13845
13846 * doc/bison.texinfo (Initial Action Decl): New.
13847
13848 2004-09-20 Akim Demaille <akim@epita.fr>
13849
13850 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
13851 clearer criterion to define it.
13852 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
13853 When reducing on an empty RHS, use the latest stacked location as
13854 location.
13855 yylloc is not always available.
13856 * data/glr.c: Likewise.
13857 Also, honor initial-actions.
13858
13859 2004-09-20 Akim Demaille <akim@epita.fr>
13860
13861 * data/yacc.c (YY_LOCATION_PRINT): New.
13862 Define when we know YYLTYPE's structure, i.e., when the default
13863 YYLLOC_DEFAULT is used.
13864 * data/c.m4 (b4_yysymprint_generate): Use it.
13865 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
13866 value of the result.
13867 (error_start_): Replace with...
13868 (error_range_): this location array.
13869 This allows to replace code relying on the implementation of
13870 locations by portable code.
13871 * data/yacc.c (yylerrsp): Replace with...
13872 (yyerror_range): this.
13873 Every time a token is popped, update yyerror_range[0], to have an
13874 accurate location for the error token.
13875 * data/glr.c (YY_LOCATION_PRINT): New.
13876 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
13877 deference a pointer.
13878 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
13879 report the location in %printers.
13880
13881 * src/scan-skel.l: Instead of abort, report error messages to ease
13882 understanding skeleton scanning failures.
13883
13884 2004-09-16 Akim Demaille <akim@epita.fr>
13885
13886 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
13887 (iterator, const_iterator): these, to be more in the C++ spirit.
13888 Also, return reverse iterators so that when displaying the stack
13889 we display its bottom first.
13890 (Parser::stack_print_, Parser::reduce_print_): Match the messages
13891 from yacc.c.
13892 We should probably use vector here though.
13893
13894 2004-09-16 Akim Demaille <akim@epita.fr>
13895
13896 Have more complete shift traces.
13897
13898 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
13899 to report Shifts instead of ad hoc YYDPRINTF invocations,
13900 including for the error token.
13901 * data/lalr1.cc (symprint_): Output the location.
13902 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
13903 output the location within the %printer.
13904 Activate GLR tests, at least to make sure they compile properly.
13905 They still don't pass though.
13906 * tests/calc.at: Adjust expect verbose output, since now "Entering
13907 state..." is on a different line than the "Shifting" message.
13908
13909 2004-09-08 Akim Demaille <akim@epita.fr>
13910
13911 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
13912 Bison directive from the Bison file to the invocation of this
13913 macro, so that these directives are passed to
13914 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
13915 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
13916 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
13917 the extra Bison directives instead of the whole series.
13918 Change the grammar so that there are recoverable errors, and
13919 unrecoverable errors. Now we can have the parser give up before
13920 consuming the whole input. As a result we now can observe that
13921 the lookahead is freed when needed.
13922 Change the parser source to parse argv[1] instead of a hard coded
13923 string.
13924 Simplify yylex, and give a value and location to EOF.
13925 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
13926 passed directives already coded in the file.
13927 Add some tests to check the location of "error".
13928 For some tests, the C++ parser is correct, and not yacc.c.
13929 For other tests, they provide different, but unsatisfying, values,
13930 so keep the C++ value so that at least one parser is "correct"
13931 according to the test suite.
13932 (Actions after errors): Remove, this is subsumed by the
13933 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
13934
13935 2004-09-06 Akim Demaille <akim@epita.fr>
13936
13937 * data/lalr1.cc: Adjust the indentation of the labels.
13938 (Parser::pop): New.
13939 Use it.
13940
13941 2004-09-06 Akim Demaille <akim@epita.fr>
13942
13943 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
13944 argument, an informative message.
13945 Call YY_SYMBOL_PRINT.
13946 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
13947 * data/lalr1.cc (destruct_): Likewise.
13948 In addition, no longer depend on b4_yysymprint_generate and
13949 b4_yydestruct_generate to generate these functions, do it "by
13950 hand".
13951
13952 2004-09-03 Akim Demaille <akim@epita.fr>
13953
13954 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
13955 invoked, yydestruct the lookahead.
13956 * tests/calc.at (Calculator $1): Update the expected lengths of
13957 traces: there is an added line for the discarded lookahead.
13958 * doc/bison.texinfo (Destructor Decl): Some rewording.
13959 Define "discarded" symbols.
13960
13961 2004-09-02 Akim Demaille <akim@epita.fr>
13962
13963 * data/lalr1.cc (translate_, destruct_): No reason to be static.
13964
13965 2004-09-02 Akim Demaille <akim@epita.fr>
13966
13967 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
13968 (YYDSYMPRINTF): Rename as...
13969 (YY_SYMBOL_PRINT): this.
13970 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
13971 two.
13972 Use it instead of direct symprint_ calls.
13973 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
13974 one.
13975
13976 2004-09-02 Akim Demaille <akim@epita.fr>
13977
13978 * data/lalr1.cc (b4_yysymprint_generate): New.
13979 (symprint_): New member function, defined when YYDEBUG.
13980 Use it consistently instead of token/nterm debugging output by
13981 hand.
13982 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
13983 %printer calls to use cdebug_ when using lalr1.cc.
13984
13985 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
13986
13987 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
13988 with #ifdef YYDEBUG.
13989
13990 2004-08-26 Akim Demaille <akim@epita.fr>
13991
13992 * doc/bison.texinfo (Implementing Loops): Rename as...
13993 (Implementing Gotos/Loops): this.
13994
13995 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
13996
13997 Adjust to latest gnulib.
13998 * bootstrap (gnulib_modules): Add xalloc-die.
13999 Set LC_ALL=C so that file names sort consistently.
14000 Prefer the gnulib copies of gettext.m4, glibc21.m4,
14001 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
14002 uintmax_t.m4, ulonglong.m4.
14003 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
14004 po.m4 since we are now using _gl.m4 instead.
14005
14006 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
14007
14008 * src/scan-action.l: Remove. Scanning of semantic actions is
14009 handled in scan-gram.l.
14010
14011 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
14012
14013 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
14014
14015 * src/location.h (struct): The file member is a uniqstr.
14016 (equal_boundaries): Use UNIQSTR_EQ for comparison.
14017
14018 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
14019
14020 Fix bug with non-%union parsers that have printers or destructors,
14021 which led to a Bison core dump. Reported by Peter Fales in
14022 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
14023
14024 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
14025 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
14026 not to our own type.
14027 * src/output.c (symbol_destructors_output, symbol_printers_output):
14028 Don't assume %union.
14029 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
14030 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
14031 UNION-FLAG. All callers changed.
14032 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
14033 Use type char, not unsigned int, when declaring an array of char;
14034 this lets us remove a cast.
14035 (Printers and Destructors): Add non-%union test cases.
14036
14037 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
14038
14039 * doc/bison.texinfo: Minor editorial changes, mostly to the new
14040 GLR writeups. E.g., avoid frenchspacing and the future tense,
14041 change "lookahead" to "look-ahead", and change "wrt" to "with
14042 respect to".
14043
14044 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
14045
14046 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
14047 New sections, split off from the GLR Parsers section. Put the new
14048 Simple GLR Parser near the start of the GLR section, for clarity.
14049 Rewrite connective text.
14050
14051 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
14052
14053 * doc/bison.texinfo (Simple GLR Parsers): New section.
14054
14055 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
14056
14057 * NEWS, TODO, doc/bison.texinfo:
14058 Use "look-ahead" instead of "lookahead", to be consistent.
14059 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
14060 while we're fixing "look-ahead".
14061 * src/conflicts.c (shift_set): Renamed from shiftset.
14062 (look_ahead_set): Renamed from lookaheadset.
14063 * src/print.c: Likewise.
14064 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
14065 name for "lookahead".

14110
14111 Spent a few hours checking out which prerequisite versions the
14112 current sources actually require. I went all the way back to
14113 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
14114 a seemingly endless set of combinations of versions more recent
14115 than that. The bottom line is that the current sources require
14116 fairly recent versions of the build tools, and it'll be some work
14117 to change this.
14118 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
14119 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
14120 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
14121 Add comments explaining why those particular versions are
14122 currently needed.
14123
14124 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
14125 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
14126 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
14127
14128 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
14129 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
14130
14131 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14132
14133 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
14134 0.11.5. Suggested by Bruno Haible.
14135 * bootstrap: Remove gettext version checking.
14136
14137 * doc/bison.texinfo (Decl Summary): Also mention that %union
14138 can depend on prerequisite types. Problem reported by Tim
14139 Van Holder.
14140
14141 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14142
14143 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
14144 * README-alpha: Don't tell people not to package this.
14145
14146 * bootstrap: Don't assume $(...) works; use `...` instead.
14147 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
14148 gettext better.
14149
14150 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
14151 put into the -d output file, and mention what to do if YYSTYPE is
14152 defined as a macro.
14153
14154 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14155
14156 Undo change made earlier today: it caused autopoint to not bring
14157 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
14158 autopoint's.
14159
14160 * bootstrap: Check that gettext version matches what's in
14161 configure.ac. Warn users to ignore robots.txt ERROR 404.
14162 * bootstrap: Undo today's earlier change (logged below).
14163 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
14164
14165 The gettext version checking is causing more trouble than it's
14166 curing; remove it. Problem reported by Paul Hilfinger.
14167
14168 * bootstrap: Issue a warning that one can expect a message
14169 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
14170 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
14171
14172 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
14173
14174 Ensure that the C++ compiler used for testing actually works on a
14175 simple test program; if not, skip the C++-related tests. Problem
14176 reported by Vin Shelton in:
14177 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

14182 * tests/local.at (AT_COMPILE_CXX): Use it.
14183
14184 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
14185
14186 * data/glr.c (yylloc): Output this macro even if locations are not
14187 being generated, as the GLR parser needs it even in that case.
14188 Problem reported by Troy A. Johnson
14189 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
14190
14191 * configure.ac (AC_INIT): Update to 1.875e.
14192
14193 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
14194
14195 * NEWS: Version 1.875d.
14196 * configure.ac (AC_INIT): Likewise.
14197 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
14198
14199 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
14200 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
14201 lalr1.cc runs afoul of the first, and the last two are no longer
14202 supported by GCC 3.4.0.
14203 * README: Mention GNU m4 1.4 or later; mention m4 patches.
14204 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
14205
14206 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
14207
14208 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
14209 unsigned int, for compatibility with latest gnulib hash module.
14210 * src/state.c (state_hash, state_hasher): Likewise.
14211 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

14231 Remove more 'intl'-related files.
14232 Don't DEFUN AM_INTL_SUBDIR twice.
14233
14234 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
14235 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
14236 strtoul.c.
14237 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
14238 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
14239 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
14240 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
14241 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
14242 * src/.cvsignore: Add *.output.
14243
14244 * src/parse-gram.y: Put copyright notice inside %{ %} so it
14245 gets copied to the output file.
14246
14247 2004-04-28 Paul Eggert <eggert@twinsun.com>
14248
14249 Get files from the gnulib and po repositories, instead of relying
14250 on them being in our CVS. Upgrade to latest versions of gnulib
14251 and Automake.
14252
14253 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
14254 * bootstrap: Bootstrap from gnulib and po repositories.
14255 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
14256 * README-cvs: Document these changes. Remove version numbers from
14257 mentions of build tools, since they change so often. Mention Flex.
14258
14259 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
14260 (gl_USE_SYSTEM_EXTENSIONS): Add.
14261 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
14262 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
14263 does this for us.
14264 (AC_ISC_POSIX): Remove; we no longer support this
14265 ancient OS, as it gets in the way of latest Autoconf & gnulib.
14266 (AC_HEADER_STDC): Remove: we now assume C89 or better.
14267 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
14268 Do not check for C89 headers, except for locale.h which is used
14269 by the Yacc library and must port to K&R hosts.
14270 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
14271 Do not check for C89 functions, except for setlocale which is
14272 used by the Yacc library.
14273 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
14274 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
14275 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,
14276 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE,
14277 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
14278 AM_GNU_GETTEXT): Remove; now done by:
14279 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
14280 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
14281 for us.
14282
14283 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
14284 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
14285 Define to empty, as gnulib.mk will do the rest for us.
14286 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
14287 for us.
14288 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
14289 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
14290
14291 * src/files.c: Include gnulib's xstrndup.h.
14292
14293 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
14294 (REALLOC): Use xnrealloc, for likewise.
14295 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
14296 (strnlen, memrchr): Remove decls; functions no longer used.
14297 Include <stpcpy.h>.
14298
14299 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

14319 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
14320 Remove, as these files are now generated automatically
14321 by bootstrap or automake.
14322
14323 * po/ChangeLog: Remove: all but one entry was a duplicate
14324 of this file, and I moved that 2000-11-02 entry here.
14325
14326 * config/.cvsignore: Add Makefile, depcomp, install-sh.
14327 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

14336 unlocked-io.h, xalloc.h, xmalloc.c, xstrdup.c, xstrndup.c,
14337 xstrndup.h.
14338 * m4/.cvsignore: Remove Makefile, Makefile.in. Add alloca.m4,
14339 dirname.m4, dos.m4, error.m4, getopt.m4, hash.m4, mbrtowc.m4,
14340 mbswidth.m4, obstack.m4, onceonly.m4, quote.m4, quotearg.m4,

14343 * src/.cvsignore: Remove *_.c.
14344
14345
14346 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
14347 support it. (The latest stable gzip doesn't.)
14348
14349 2004-04-27 Paul Eggert <eggert@twinsun.com>
14350
14351 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
14352 case, as stos_ is now used by destructors due to the 2004-02-09
14353 change.
14354
14355 Remove more K&R C support.
14356 * lib/libiberty.y (PARAMS): Remove. All uses removed.
14357 * lib/subpipe.c (errno): Remove decl.
14358 Include <stdlib.h> unconditionally.
14359 (EXIT_FAILURE): Remove macro.
14360 * src/complain.c (vfprintf, strerror): Remove.
14361 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
14362 unconditionally.
14363 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
14364 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
14365 (strchr, strspn, memchr): Remove decls.
14366 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h

14369 unconditionally.
14370
14371 * src/complain.c (_): Remove useless defn, as system.h defines this.
14372
14373 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
14374 with latest obstack.h.
14375 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
14376 to procedure types, as obstack.h now does that for us.
14377 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
14378
14379 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
14380 so that this include file can stand alone.
14381 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
14382 does this now. Include subpipe.h first after config.h, to
14383 test whether it can stand alone.
14384
14385 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
14386 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
14387 unused declaration.
14388
14389 * tests/synclines.at (%union synch line): Put a dummy member in
14390 the union, because empty unions aren't allowed in C. Caught
14391 by GCC 3.4.0.
14392
14393 2004-04-13 Jim Meyering <jim@meyering.net>
14394
14395 * src/conflicts.c (conflicts_print): Correct format string typo:
14396 use `%%' to produce literal `%'. (trivial change)
14397
14398 2004-03-30 Paul Eggert <eggert@twinsun.com>
14399
14400 * src/getargs.c (version): Update copyright year to 2004.
14401
14402 * data/c.m4 (b4_int_type): Use 'short int' rather than
14403 'short', and similarly for 'long', 'unsigned', etc.
14404 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
14405 yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,
14406 yy_yypstack, yydumpstack): Likewise.
14407 * data/lalr1.cc (user_token_number_max_, user_token_number_max_,
14408 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):
14409 Likewise.
14410 * data/yacc.c (b4_int_type, yyss, YYSTACK_BYTES, yysigned_char,
14411 yy_stack_print, yyparse): Likewise.

14428 * src/state.h (state_number, transitions, errs, reductions,
14429 struct state): Likewise.
14430 * src/symtab.h (symbol_number, struct symbol): Likewise.
14431 * src/tables.c (vector_number, tally, action_number,
14432 default_goto, goto_actions): Likewise.
14433 * tests/existing.at (GNU Cim Grammar): Likewise.
14434 * tests/regression.at (Web2c Actions): Likewise.
14435
14436 * src/output.c (muscle_insert_short_int_table): Renamed from

14438
14439 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
14440
14441 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
14442 (declaration): Replace expected_conflicts with expected_sr_conflicts.
14443 Add %expect-rr rule.
14444
14445 * src/scan-gram.l: Recognize %expect-rr.
14446
14447 * src/conflicts.h (expected_sr_conflicts): Rename from
14448 expected_conflicts.
14449 (expected_rr_conflicts): Declare.
14450
14451 * src/conflicts.c (expected_sr_conflicts): Rename from
14452 expected_conflicts.
14453 (expected_rr_conflicts): Define.
14454 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
14455 for GLR parsers.
14456 Use expected_sr_conflicts in place of expected_conflicts.
14457 Warn if expected_rr_conflicts used in non-GLR parser.
14458
14459 * doc/bison.texinfo: Add documentation for %expect-rr.
14460
14461 2004-03-08 Paul Eggert <eggert@gnu.org>
14462
14463 Add support for hex token numbers. Suggested by Odd Arild Olsen in
14464 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
14465
14466 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
14467 in lalr1.cc.
14468 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
14469 * src/scan-gram.l (scan_integer): New function.
14470 ({int}): Use it.
14471 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
14472 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
14473 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
14474 Say "long int", not "long", for uniformity with GNU style.
14475
14476 2004-02-25 Paul Eggert <eggert@twinsun.com>
14477
14478 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
14479 compilers. This fixes a problem with Intel's C++ compiler being
14480 chatty, reported by Guido Trentalancia in
14481 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
14482
14483 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
14484
14485 Support %destructor and merge error locations in lalr1.cc.
14486
14487 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
14488 (Parser::stos_): Define unconditionally.
14489 (Parser::destruct_): New method. Generate its body with
14490 b4_yydestruct_generate.
14491 (Parser::error_start_): New attribute.
14492 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
14493 token which are discarded.
14494 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
14495 error_start_ when erroneous token are discarded.
14496 (Parser::parse) <yyerrlab1>: Compute the location of the error
14497 token so that it covers all the discarded tokens.
14498 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
14499 it can be called with `%skeleton "lalr1.cc"', and do that.
14500
14501 2004-02-02 Paul Eggert <eggert@twinsun.com>
14502
14503 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
14504 $(top_srcdir)/lib and ../lib. This fixes a bug reported
14505 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
14506 There's no need to mention top_builddir since Automake does that
14507 for us.
14508 (INCLUDES): Remove, as Automake says it's obsolescent.
14509 Contents migrated into AM_CPPFLAGS as described above.
14510 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
14511
14512 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
14513
14514 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
14515 (yyreportSyntaxError): Handle case where lookahead token is
14516 YYEMPTY.
14517
14518 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14519
14520 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
14521 resulting parsers are compilable with C++.
14522
14523 2003-12-23 Paul Eggert <eggert@twinsun.com>
14524
14525 * config/depcomp, config/install-sh: Sync with Automake 1.8.
14526 * src/output.c (output_skeleton): Rename local var.
14527 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
14528 Bison tokens, as this runs afoul of the 2003-10-07 change that
14529 disallowed NUL bytes in character constants or string literals.
14530
14531 * tests/local.at: Require Autoconf 2.59's Autotest.
14532 * tests/testsuite.at: Don't include local.at, since we now assume
14533 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
14534 including it.
14535 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
14536 multiple inclusion warnings.
14537

14539
14540 * doc/bison.texinfo (How Can I Reset the Parser): More about start
14541 conditions.

14543
14544 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
14545
14546 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
14547
14548 2003-10-07 Paul Eggert <eggert@twinsun.com>
14549
14550 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
14551 if testsuite doesn't exist.
14552
14553 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
14554 literals, unfortunately.
14555 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
14556 Complain about NUL bytes in character constants or string literals.
14557
14558 2003-10-05 Paul Eggert <eggert@twinsun.com>
14559
14560 * NEWS: Don't document %no-default-prec, as it's still
14561 too experimental.
14562 * doc/bison.texinfo: Document %no-default-prec only if
14563 the defaultprec flag is set. Normally it's not.
14564
14565 2003-10-04 Paul Eggert <eggert@twinsun.com>
14566
14567 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
14568 non-modifiable lvalue, instead of a modifiable one.
14569 * doc/bison.texinfo (Actions): Document that $$ can
14570 be assigned to. Do not claim that $$ and $N are
14571 array element references: user code should not rely on this.
14572
14573 2003-10-01 Paul Eggert <eggert@twinsun.com>
14574
14575 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
14576 (grammar_declaration): Use it.
14577 * src/scan-gram.l: New token %no-default-prec.
14578 * tests/conflicts.at: Revamp tests to use %no-default-prec.
14579 * NEWS, doc/bison.texinfo: Document the above.
14580
14581 2003-10-01 Akim Demaille <akim@epita.fr>
14582
14583 VCG no longer supports long_straight_phase.
14584
14585 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
14586 * src/print_graph.c (print_graph): Adjust.
14587
14588 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
14589 and Paul Eggert <eggert@twinsun.com>
14590
14591 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
14592 Table of Symbols): Document %default-prec.
14593 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
14594 (grammar_declaration): Set default_prec on %default-prec.
14595 * src/scan-gram.l (%default-prec): New token.
14596 * src/reader.h (default_prec): New flag.
14597 * src/reader.c: Likewise.
14598 (packgram): Handle it.
14599 * tests/conflicts.at (%default-prec without %prec,
14600 %default-prec with %prec, %default-prec 1): New tests.
14601
14602 2003-09-30 Paul Eggert <eggert@twinsun.com>
14603
14604 * tests/testsuite.at: Include local.at, not input.at, fixing
14605 a typo in the 2003-08-25 patch.
14606
14607 2003-08-27 Akim Demaille <akim@epita.fr>
14608
14609 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
14610 GCC warnings.
14611
14612 2003-08-26 Akim Demaille <akim@epita.fr>
14613
14614 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
14615 "<\#" to avoid magic from Gnus when posting parts of this script.
14616
14617 2003-08-26 Akim Demaille <akim@epita.fr>
14618
14619 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
14620 (Parser::parse): here.
14621 Adjust: nerrs and errstatus is now replaced by...
14622 (Parser::nerrs_, Parser::errstatus_): New.
14623
14624 2003-08-25 Akim Demaille <akim@epita.fr>
14625
14626 * config/announce-gen, Makefile.cfg: New.
14627 * Makefile.am: Adjust.
14628 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
14629 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
14630
14631 2003-08-25 Akim Demaille <akim@epita.fr>
14632
14633 When reducing initial empty rules, Bison parser read an initial
14634 location that is not defined. This results in garbage, and that
14635 affects Bison's own parser. Therefore we need (i) to extend Bison
14636 to support a means to initialize this location, and (ii) to use
14637 this CVS Bison to fix CVS Bison's parser.
14638
14639 * src/reader.h, reader.c (epilogue_augment): Remove, replace
14640 with...
14641 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
14642 * src/parse-gram.y: Adjust.
14643 (%initial-action): New.
14644 (%error-verbose): Since we require CVS Bison, there is no reason
14645 not to use it.
14646 * src/scan-gram.l: Adjust.
14647 * src/Makefile.am (YACC): New, to make sure we use our own parser.
14648 * data/yacc.c (yyparse): Use b4_initial_action.
14649
14650 2003-08-25 Akim Demaille <akim@epita.fr>
14651
14652 * doc/bison.texinfo: Don't promote stdout for error messages.
14653
14654 2003-08-25 Akim Demaille <akim@epita.fr>
14655
14656 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
14657 From Alexandre Duret-Lutz.
14658
14659 2003-08-25 Akim Demaille <akim@epita.fr>
14660
14661 Version 1.875c.
14662
14663 2003-08-25 Akim Demaille <akim@epita.fr>
14664
14665 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
14666 Use them.
14667
14668 2003-08-25 Akim Demaille <akim@epita.fr>
14669
14670 * data/lalr1.cc (Parser::reduce_print_): New.
14671 Use it.
14672
14673 2003-08-25 Akim Demaille <akim@epita.fr>
14674
14675 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
14676 error recovery loops. This patch is based on
14677 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
14678 Also, augment the similarity between lalr1.cc and yacc.c.
14679 Note: the locations of error recovery rules are not correct yet.
14680
14681 * data/lalr1.cc: Comment changes to augment the similarity between
14682 lalr1.cc and yacc.c.
14683 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
14684 (yyerrlab1): Remove, but where it used to be (now the bottom part of
14685 yyerrlab), when hitting EOF, pop the whole stack here instead of
14686 merely falling thru the default error handling mechanism.
14687 (yyerrorlab): New label, with the old contents of YYERROR,
14688 plus the following change: pop the stack of rhs corresponding
14689 to the production that invoked YYERROR. That is how Yacc
14690 behaves (required by POSIX).
14691 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
14692 fail.
14693
14694 2003-08-25 Akim Demaille <akim@epita.fr>
14695
14696 Tune local.at so that people can "autom4te -l autotest calc.at -o
14697 calc" for instance, to extract a sub test suite.
14698
14699 * tests/testsuite.at: Move the initialization, Autotest version
14700 requirement, and AT_TESTED invocation into...
14701 * tests/local.at: here.
14702 * tests/testsuite.at: Include it for compatibility with Autoconf
14703 2.57.
14704 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
14705 be ignore.
14706
14707 2003-08-04 Paul Eggert <eggert@twinsun.com>
14708
14709 Rework code slightly to avoid gcc -Wtraditional warnings.
14710 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
14711 The returned value is now stored in *YY0. All callers changed.
14712 * src/output.c (merge_output): Adjust to the above change.
14713
14714 2003-07-26 Paul Eggert <eggert@twinsun.com>
14715
14716 * data/glr.c (YYASSERT): New macro.
14717 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
14718 yyresolveStates, yyprocessOneStack):
14719 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
14720 Derived from a suggestion by Frank Heckenbach.
14721
14722 2003-07-25 Paul Eggert <eggert@twinsun.com>
14723
14724 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
14725 for portability to K&R C (after ansi2knr, presumably). See
14726 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
14727 by Frank Heckenbach, though I have omitted the structure-initialization
14728 part of his glr-knr.diff patch since I recall that the Portable
14729 C Compiler didn't require that change.
14730
14731 Let the user specify how to allocate and free memory.
14732 Derived from a suggestion by Frank Heckenbach in
14733 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
14734 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
14735 All uses of free, malloc, realloc changed to use these macros,
14736 and unnecessary casts removed.
14737 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
14738
14739 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
14740
14741 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
14742 use s.empty() rather than s == "" to test for empty string; see
14743 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
14744 (trivial change)
14745
14746 2003-06-25 Akim Demaille <akim@epita.fr>
14747
14748 * config/depcomp, config/install-sh: Update from masters.
14749
14750 2003-06-20 Paul Eggert <eggert@twinsun.com>
14751
14752 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
14753 and return properly parenthesized result.
14754 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
14755 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
14756 Remove unnecessary parentheses from uses.
14757 * doc/bison.texinfo (Location Default Action): Describe the
14758 conventions for parentheses.
14759
14760 2003-06-19 Paul Eggert <eggert@twinsun.com>
14761
14762 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
14763 yyreportTree): Do not assume that size_t is the same width as int,
14764 when printing sizes. Print sizes using an unsigned format.
14765 Problem reported by Frank Heckenbach in
14766 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
14767
14768 Port to Forte Developer 7 C compiler.
14769 * data/glr.c (struct YYLTYPE): If locations are not being used,
14770 declare a single dummy member, as empty structs do not conform
14771 to the C standard.
14772 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
14773 the Forte Developer 7 C compiler complains that end-of-loop
14774 code is not reached.
14775
14776 2003-06-17 Paul Eggert <eggert@twinsun.com>
14777
14778 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
14779 avoid warnings from picky compilers about redefinition of PARAMS.
14780
14781 2003-06-17 Paul Eggert <eggert@twinsun.com>
14782
14783 Version 1.875b.
14784
14785 * NEWS: Document 1.875b.
14786
14787 * lib/bbitset.h: Do not include config.h; that's the includer's job.
14788 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
14789 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
14790 Don't use 'index' in comments, as it's a builtin fn on some hosts.
14791 * lib/bitset_stats.c: Include gettext.h unconditionally, as
14792 per recent gettext manual's suggestion.
14793 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
14794 Use prototypes, not old-style definitions.
14795 * lib/lbitset.c (lbitset_unused_clear): Likewise.
14796 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
14797 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
14798 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
14799 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
14800 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
14801 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
14802 vbitset_or_and_cmp, vbitset_copy): Likewise.
14803
14804 * lib/libiberty.h: Do not include config.h; that's the includer's job.
14805 Do not include <stdlib.h>.
14806 (PARAMS): Define unconditionally for C89.
14807 (ATTRIBUTE_NORETURN): Remove.
14808 (ATTRIBUTE_UNUSED): Define unconditionally.
14809
14810 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
14811 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
14812 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
14813 * lib/vbitset.c, lib/vbitset.h: New files.
14814 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
14815 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
14816 from libbitset.
14817
14818 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
14819 `How Can I Reset @code{yyparse}', since texinfo does not allow
14820 arbitrary @ in node names.
14821
14822 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
14823 shouldn't be needed according to the gettext 0.12.1 documentation
14824 but which seem to be needed anyway: codeset.m4 glibc21.m4
14825 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
14826 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
14827 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
14828
14829 * lib/.cvsignore: Add stdbool.h.
14830 * m4/.cvsignore: Add nls.m4, po.m4.
14831
14832 Upgrade to CVS gnulib.
14833 * stdbool_.h: File renamed from stdbool.h.in.
14834 * configure.ac (AM_STDBOOL_H): Invoke this instead of
14835 AC_HEADER_STDBOOL.
14836 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
14837 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
14838 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
14839 (MOSTLYCLEANFILES): New var.
14840 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
14841 (stdbool.h): New rule.
14842 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
14843 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
14844 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
14845 m4/quote.m4: Upgrade to today's gnulib.
14846
14847 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
14848 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
14849 the tests right now.
14850 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
14851 yyerror are declared before use; C99 requires this.
14852
14853 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14854
14855 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
14856 first.
14857 (yyrecoverSyntaxError): Correct the logic for setting and testing
14858 yyerrState.
14859 Correct comment on handling EOF.
14860 Allow states with only a default reduction, rather than failing
14861 (I can't quite reconstruct why these were not allowed before).
14862
14863 Fixes to avoid problem that $-N rules in GLR parsers can cause
14864 buffer overruns, corrupting state.
14865
14866 * src/output.c (prepare_rules): Output max_left_semantic_context
14867 definition.
14868 * src/reader.h (max_left_semantic_context): New variable declaration.
14869 * src/scan-gram.l (max_left_semantic_context): Define.
14870 (handle_action_dollar): Update max_left_semantic_context.
14871 * data/glr.c (YYMAXLEFT): New definition.
14872 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
14873 (yyresolveAction): Ditto.
14874
14875 Fixes to problems with location handling in GLR parsers reported by
14876 Frank Heckenbach (2003/06/05).
14877
14878 * data/glr.c (YYLTYPE): Make trivial if locations not used.
14879 (YYRHSLOC): Add parentheses, and define only if locations used.
14880 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
14881 locations not used.
14882 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
14883 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
14884
14885 * tests/cxx-type.at: Exercise location information; update tests
14886 to differentiate output with and without locations.
14887 Remove forward declarations of yylex and yyerror---caused errors
14888 because default YYLTYPE not yet defined.
14889 Change semantic actions to compute strings, rather than printing
14890 them directly (to test proper passing of semantics values). Change
14891 output to prefix notation and update test data and expected results.
14892 (yylex): Track locations.
14893 (stmtMerge): Return value rather than printing, and include arguments
14894 in value.
14895
14896 2003-06-03 Paul Eggert <eggert@twinsun.com>
14897
14898 Avoid warnings generated by GCC 2.95.4 when Bison is
14899 configured with --enable-gcc-warnings.
14900 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
14901 yy::]b4_parser_class_name[::translate_,
14902 yy::Stack::operator[] (unsigned),
14903 yy::Stack::operator[] (unsigned) const,
14904 yy::Slice::operator[] (unsigned),
14905 yy::Slice::operator[] (unsigned) const):
14906 Rename local vars to avoid warnings.
14907 * tests/glr-regression.at (Improper handling of embedded actions
14908 and $-N in GLR parsers): Remove unused local variable from yylex.
14909 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
14910 (void) as arg when not pure, since we now assume C89 when building
14911 Bison. Pacify GCC by using parameter.
14912
14913 2003-06-02 Paul Eggert <eggert@twinsun.com>
14914
14915 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
14916 yy::Location::lines, yy::Location::columns): Rename arguments
14917 to avoid shadowing; this removes a warning generated by GCC 3.3.
14918
14919 2003-06-01 Paul Eggert <eggert@twinsun.com>
14920
14921 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
14922 to g++, as GCC 3.3 complains if you do it.
14923 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
14924 everything that WARNING_CFLAGS has, except omit warnings
14925 not suitable for C++.
14926 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
14927 * tests/atlocal.in (CXXFLAGS): New var.
14928 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
14929
14930 Fix a GLR parser bug I reported in February; see
14931 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
14932 The problem was that GLR parsers did not conform to the C standard,
14933 because actions like { $1 = $2 + $3; } expanded to expressions
14934 that invoked YYFILL in separate subexpressions, and YYFILL assigned
14935 to a local variable. The C standard says that expressions
14936 like (var = f ()) + (var = f ()) have undefined behavior.
14937 Another problem was that GCC sometimes issues warnings that
14938 yyfill and its parameters are unused.
14939
14940 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
14941 as possibly unused.
14942 (yyfill): New function.
14943 (YYFILL): Use it.
14944 (yyuserAction): Change type of yynormal to bool, so that it matches
14945 the new yyfill signature. Mark it as possibly unused.
14946
14947
14948 Follow up on a bug I reported in February, where a Bison-generated
14949 parser can loop. Provide a test case and a fix for yacc.c. I
14950 don't have a fix for lalr1.cc or for glr.c, unfortunately.
14951 The original bug report is in:
14952 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
14953
14954 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
14955 macro's size was becoming unwieldy.
14956 (yyerrlab): Do not discard an empty lookahead symbol, as this
14957 might destroy garbage.
14958 (yyerrorlab): New label, with the old contents of YYERROR,
14959 plus the following change: pop the stack of rhs corresponding
14960 to the production that invoked YYERROR. That is how Yacc
14961 behaves, and POSIX requires this behavior.
14962 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
14963 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
14964 Define 'alarm' to do nothing if unistd.h is not available.
14965 Add a new rule "exp: '-' error;" to test the above change to
14966 data/yacc.c. Use 'alarm' to abort any test taking longer than
14967 10 seconds, as it's probably looping.
14968 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
14969 Also, the new yacc.c generates two fewer diagnostics for an
14970 existing test.
14971
14972 2003-05-24 Paul Eggert <eggert@twinsun.com>
14973
14974 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
14975 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
14976 This fixes a problem reported by John Bowman when the Compaq/HP
14977 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
14978 -ansi -Wall -gall).
14979 * data/yacc.c (union yyalloc): Likewise.
14980 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
14981
14982 Switch from 'int' to 'bool' where that makes sense.
14983
14984 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
14985 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
14986 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
14987 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
14988 Return or accept bool, not int. All callers changed.
14989 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,

15008 lbitset_xor_cmp): Likewise.
15009 * lib/bbitset.h: Include <stdbool.h>.
15010 (struct bitset_vtable): The following members now return bool, not
15011 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
15012 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
15013 or_and_cmp).
15014 * src/conflicts.c (count_rr_conflicts): Likewise.
15015 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
15016 All uses changed.

15018 * lib/lbitset.c (lbitset_obstack_init): Likewise.
15019 * src/getargs.c (debug_flag, defines_flag, locations_flag,

15036 * src/output.c (prepare): Use it.
15037 * src/output.c (token_definitions_output,
15038 symbol_destructors_output, symbol_destructors_output): Use string,
15039 not boolean integer, to keep track of whether to output separator.
15040 * src/print_graph.c (print_core): Likewise.
15041 * src/state.c (state_rule_lookaheads_print): Likewise.
15042

15044
15045 2003-05-14 Paul Eggert <eggert@twinsun.com>
15046
15047 * src/parse-gram.y (rules_or_grammar_declaration): Require a
15048 semicolon after a grammar declaration, in the interest of possible
15049 future changes to the Bison input language.
15050 Do not allow a stray semicolon at the start of the grammar.
15051 (rhses.1): Allow one or more semicolons after any rule, including
15052 just before "|" as required by POSIX.
15053 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
15054 grammar.
15055
15056 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
15057
15058 %parse-param support for lalr1.cc.
15059
15060 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
15061 b4_cc_constructor_calls, b4_cc_constructor_call,
15062 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
15063 definitions.
15064 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
15065 parse-param arguments.
15066 (yy::b4_parser_class_name): Declare instance variables to
15067 hold parse-param arguments.
15068 * tests/calc.at: s/value/semantic_value/ because value clashes
15069 with a member of yy::b4_parser_class_name. Adjust C++ code
15070 to handle %parse-param. Enable %parse-param test in C++.
15071
15072 2003-05-12 Paul Eggert <eggert@twinsun.com>
15073
15074 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
15075 English a bit. Fix fclose typo. Change "const char" to "char
15076 const", and use ANSI C rather than K&R for "main". Suggest
15077 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
15078 and suggest yy_switch_to_buffer.
15079
15080 2003-05-05 Paul Eggert <eggert@twinsun.com>
15081
15082 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
15083 C89. This avoids a diagnostic on compilers that define __STDC__
15084 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
15085 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
15086
15087 2003-05-03 Paul Eggert <eggert@twinsun.com>
15088
15089 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
15090 Do not overrun array bounds.
15091 This should fix a bug reported today by Olatunji Oluwabukunmi in
15092 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
15093
15094 2003-04-29 Akim Demaille <akim@epita.fr>
15095
15096 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
15097 * src/getargs.c, src/getargs.h: here, as bool, not int.
15098 (nondeterministic_parser): New.
15099 * src/parse-gram.y, src/scan-gram.l: Support
15100 %nondeterministic-parser.
15101 * src/output.c (prepare): Use nondeterministic_parser instead
15102 of glr_parser where appropriate.
15103 * src/tables.c (conflict_row, action_row, save_row)
15104 (token_actions, token_actions, pack_vector): Ditto.
15105
15106 2003-04-29 Akim Demaille <akim@epita.fr>
15107
15108 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
15109
15110 2003-04-29 Akim Demaille <akim@epita.fr>
15111
15112 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
15113 with %pure-parser and %locations to exercise the patch from Yakov
15114 Markovitch below.
15115
15116 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
15117
15118 * data/yacc.c: (b4_lex_param): Corrected for the case where
15119 %lex-param is provided and %pure-parser isn't.
15120
15121 2003-04-27 Paul Eggert <eggert@twinsun.com>
15122
15123 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
15124 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
15125 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
15126 if it is not defined.
15127 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
15128
15129 2003-04-26 Paul Eggert <eggert@twinsun.com>
15130
15131 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
15132 Declare to be of type suitable for the ninf value itself, not of
15133 type suitable for the corresponding table, since the latter might
15134 be unsigned but the ninf value might be negative. This fixes a
15135 bug reported by Alexandre Duret-Lutz in
15136 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
15137
15138 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
15139 invokes it. We shouldn't invoke it twice because it will attempt
15140 to put error.o in the archive twice. This fixes a glitch reported
15141 by Martin Mokrejs in
15142 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
15143
15144 2003-04-21 Paul Eggert <eggert@twinsun.com>
15145
15146 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
15147 to gnulib.
15148
15149 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
15150
15151 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
15152 Fix obvious typo that results in uncompilable GLR parsers
15153 when both %pure-parser and %locations are used. (trivial change)
15154
15155 2003-04-17 Paul Eggert <eggert@twinsun.com>
15156
15157 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
15158 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
15159 Do not insert the expected token via unput, as this runs afoul
15160 of a POSIX-compatibility bug in flex 2.5.31.
15161 All uses changed to BEGIN the parent state,
15162 since we no longer insert the expected token via unput.
15163 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
15164 that is no longer emitted after the above change.
15165
15166 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
15167 the first one. This change is from Paul Hilfinger, and it fixes
15168 regression reported by Werner Lemberg in
15169 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
15170
15171 (resolve_sr_conflict): Don't invoke state_errs_set
15172 unless one or more tokens have been explicitly made errors.
15173 Otherwise, the above change causes Bison to abort.
15174
15175 * tests/existing.at (GNU pic Grammar): New test case, taken from
15176 Lemberg's email.
15177
15178 2003-03-31 Akim Demaille <akim@epita.fr>
15179
15180 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
15181
15182 2003-03-31 Akim Demaille <akim@epita.fr>
15183
15184 * src/output.c (prepare_symbols): Avoid trailing spaces in the
15185 output.
15186
15187 2003-03-31 Akim Demaille <akim@epita.fr>
15188
15189 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
15190 From Paul Hilfinger.
15191
15192 2003-03-29 Akim Demaille <akim@epita.fr>
15193
15194 * m4/error.m4: Do not put under dynamic conditions some code which
15195 expansion is under static control.
15196
15197 2003-03-29 Akim Demaille <akim@epita.fr>
15198
15199 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
15200
15201 2003-03-29 Akim Demaille <akim@epita.fr>
15202
15203 * doc/bison.texinfo (Strings are Destroyed): New.
15204
15205 2003-03-13 Paul Eggert <eggert@twinsun.com>
15206
15207 * .cvsignore: Add configure.lineno.
15208 * src/.cvsignore: Add yacc.
15209 * tests/.cvsignore: Add testsuite.log.
15210 * doc/fdl.texi: Sync with latest FSF version.
15211
15212 2003-03-12 Paul Eggert <eggert@twinsun.com>
15213
15214 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
15215 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
15216 cursor, instead of leaving it undefined. This fixes a bug
15217 reported by Tim Van Holder in
15218 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
15219 * tests/input.at (Torturing the Scanner): Test the scanner on
15220 an empty input file, which was Tim Van Holder's test case.
15221
15222 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
15223 <sys/resource.h> can be included, include sys/time.h and
15224 sys/times.h first, if available. This works around the SunOS
15225 4.1.4 porting bug reported by Bruce Becker in
15226 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
15227
15228 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
15229 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
15230 AC_HEADER_SYS_WAIT.
15231
15232 Merge changes from gnulib. This was prompted because the CVS
15233 snapshot didn't build on Solaris 7 due to strnlen problems.
15234
15235 These changes need to be merged back into gnulib:
15236 * lib/hash.c: Include <stdbool.h> unconditionally.
15237 * m4/onceonly.m4 (m4_quote): New macro.
15238 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
15239 Quote AC_FOREACH variable-expansions properly.
15240 The 2003-01-03 obstack.h change also needs merging.
15241 {end of changes requiring merging}
15242
15243 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
15244 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
15245 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
15246 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
15247 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
15248 New files, imported from gnulib.
15249 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
15250 above.
15251
15252 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
15253 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
15254 gnulib sources.
15255
15256 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
15257 Add.
15258 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
15259 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
15260 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
15261 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
15262 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
15263 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
15264 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
15265 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
15266 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
15267 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
15268 (jm_PREREQ_ARGMATCH): Remove.
15269 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
15270 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
15271
15272 * src/system.h: Include <stdbool.h> unconditionally.
15273
15274 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
15275 assuming at least C89 in the bitset code for some time now.
15276
15277 2003-03-03 Akim Demaille <akim@epita.fr>
15278
15279 * ro.po: New.
15280
15281 2003-03-02 Akim Demaille <akim@epita.fr>
15282
15283 * doc/bison.texinfo (Table of Symbols): Reactivate the
15284 documentation for %lex-param, and %parse-param.
15285
15286 2003-03-02 Akim Demaille <akim@epita.fr>
15287
15288 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
15289 generate verbose error messages.
15290 Use the number of tokens as an upper bound in yytname, as it
15291 cannot be a non terminal.
15292
15293 2003-03-02 Akim Demaille <akim@epita.fr>
15294
15295 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
15296 message.
15297
15298 2003-03-02 Akim Demaille <akim@epita.fr>
15299
15300 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
15301 Use them to exercise yycheck overrun.
15302 Based on Andrew Suffield's grammar.
15303
15304 2003-03-02 Akim Demaille <akim@epita.fr>
15305
15306 Create tests/local.at for Bison generic testing macros.
15307
15308 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
15309 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
15310 This new file.
15311 * tests/calc.at (AT_CHECK_CALC): Adjust.
15312 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
15313 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
15314 * tests/local.at: here.
15315 (AT_COMPILE_CXX): Tags the tests using it as c++.
15316 Ignore the test if CXX is not functional.
15317
15318 2003-03-01 Paul Eggert <eggert@twinsun.com>
15319
15320 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
15321 not loc->end, since loc->end might contain garbage and this leads
15322 to undefined behavior on some platforms.
15323 (id_loc, token_start): Use (IF_LINTed) initial values that do not
15324 depend on *loc, so that the reader doesn't give the the false
15325 impression that *loc is initialized.
15326 (<INITIAL>"%%"): Do not bother setting code_start, since its value
15327 does not survive the return.
15328
15329 2003-03-01 Akim Demaille <akim@epita.fr>
15330
15331 * src/scan-gram.l (code_start): Always initialize it when entering
15332 into yylex, as SC_EPILOGUE is activated *before* the corresponding
15333 yylex invocation. An alternative would be making it static, but
15334 then it starts with the second %%'s beginning, instead of its end.
15335
15336 2003-02-28 Paul Eggert <eggert@twinsun.com>
15337
15338 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
15339 around a UnixWare 7.1.1 porting bug reported by John Hughes in
15340 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
15341
15342 2003-02-26 Paul Eggert <eggert@twinsun.com>
15343
15344 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
15345 Remove Sequent/Pyramid discussion (nobody uses them any more).
15346 Merge VMS and MS-DOS discussion; these ports may well be dead
15347 but let's keep mentioning them for now. Put <> around email
15348 addresses. Add copyright notice.
15349
15350 2003-02-24 Paul Eggert <eggert@twinsun.com>
15351
15352 * data/glr.c (yy_reduce_print): yylineno -> yylno,
15353 to avoid collision with flex use of yylineno.
15354 Problem reported by Bruce Lilly in
15355 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
15356 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
15357 * data/yacc.c (yy_reduce_print): Likewise.
15358

15360
15361 2003-02-21 Akim Demaille <akim@epita.fr>
15362
15363 * data/lalr1.cc: Use temporary variables instead of casts to
15364 change integer types.
15365 Suggested by Paul Eggert.
15366
15367 2003-02-21 Akim Demaille <akim@epita.fr>
15368
15369 * doc/bison.texinfo: Use "location" consistently to refer to @n,
15370 to avoid confusions with lalr1.cc's notion of Position.
15371 Suggested by Paul Eggert.
15372
15373 2003-02-20 Akim Demaille <akim@epita.fr>
15374
15375 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
15376 before initial_columns.
15377 (location.hh): Use consistent variable names when defining the
15378 operator<<.
15379 Use "last" so that we subtract from Positions, not from unsigned.
15380
15381 2003-02-20 Akim Demaille <akim@epita.fr>
15382
15383 * data/lalr1.cc (position.hh): New subfile, including the extended
15384 and Doxygen'ed documentation of class Position.
15385 (location.hh): Use it.
15386 Document a` la Doxygen.
15387 With the help of Benoit Perrot.
15388
15389 2003-02-20 Akim Demaille <akim@epita.fr>
15390
15391 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
15392 AT_YACC_IF.
15393 Redefine AT_YYERROR_SEES_LOC_IF using it.
15394 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
15395 not defined.
15396 Don't use the location in yy::Parser::error_ and
15397 yy::Parser::print_ when not %locations.
15398 Activate more lalr1.cc tests.
15399
15400 2003-02-19 Akim Demaille <akim@epita.fr>
15401
15402 * data/lalr1.cc: When displaying a line number, be sure to make it
15403 an int.
15404
15405 2003-02-19 Akim Demaille <akim@epita.fr>
15406
15407 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
15408 Remove, useless.
15409 (YYABORT, YYACCEPT, YYERROR): New.
15410 * tests/calc.at: Renable the lalr1.cc test.
15411
15412 2003-02-19 Akim Demaille <akim@epita.fr>
15413
15414 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
15415 error recovery, mixing with/without pops and discarding of the
15416 lookahead.
15417 Exercise YYERROR.
15418 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
15419
15420 2003-02-17 Paul Eggert <eggert@twinsun.com>
15421
15422 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
15423 * tests/testsuite.at (AT_COMPILE): Use them.
15424 This fixes the testsuite problem reported by Robert Lentz in
15425 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
15426
15427 2003-02-12 Paul Eggert <eggert@twinsun.com>
15428
15429 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
15430 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
15431 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
15432 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
15433 Check for malloc failure, for consistency with yacc.c.
15434 (yytname_size): Remove, for consistency with yacc.c.
15435
15436 The bug still remains in data/lalr1.cc, as I didn't have time
15437 to fix it there.
15438
15439 2003-02-06 Akim Demaille <akim@epita.fr>
15440
15441 * configure.ac (GXX): Rename as...
15442 (CXX): this, to keep the original Autoconf semantics.
15443 Require 2.57.
15444 * data/lalr1.cc: Fix b4_copyright invocations.
15445 If YYDEBUG is not defined, don't depend upon name_ being defined.
15446 (location.hh): Include string and iostream.
15447 (Position::filename): New member.
15448 (Position::Position ()): New.
15449 (operator<< (Position)): New.
15450 (operator- (Position, int)): New.
15451 (Location::first, Location::last): Rename as...
15452 (Location::begin, Location::end): these, to mock the conventional
15453 iterator names.

15455 * tests/atlocal.in (CXX): New.
15456 * tests/testsuite.at (AT_COMPILE_CXX): New.
15457 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
15458 locations in a more synthetic way.
15459 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
15460 lalr1.cc is used.
15461 Adjust the C locations to match those from Emacs: first column is
15462 column 0.
15463 Change all the expected results.
15464 Conform to the GCS: simplify the locations when applicable.
15465 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
15466 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
15467 these CPP macros with the m4 macros new defined by...
15468 (AT_CHECK_PUSHDEFS): this, i.e.:
15469 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
15470 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
15471 New macros.
15472 (AT_CHECK_POPDEFS): Undefine them.
15473 (AT_CHECK_CALC_LALR1_CC): New.
15474 Use it for the first lalr1.cc test.
15475
15476 2003-02-04 Akim Demaille <akim@epita.fr>
15477
15478 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
15479 Location as is defined.
15480
15481 2003-02-04 Akim Demaille <akim@epita.fr>
15482
15483 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
15484 name_ being defined.
15485
15486 2003-02-03 Paul Eggert <eggert@twinsun.com>
15487
15488 * src/gram.h (start_symbol): Remove unused decl.
15489
15490 Use more-consistent naming conventions for local vars.
15491
15492 * src/derives.c (derives_compute): Change type of local var from
15493 int to rule_number.
15494 * src/gram.c (grammar_rules_partial_print): Likewise.
15495 * src/print.c (print_core): Likewise.
15496 * src/reduce.c (reduce_grammar_tables): Likewise.
15497
15498 * src/gram.c (grammar_dump): Change name of item_number *
15499 local var from r to rp.
15500 * src/nullable.c (nullable_compute): Likewise.
15501
15502 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
15503
15504 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
15505 for symbol or symbol_number var.
15506 * src/reader.c (grammar_start_symbol_set): Likewise.
15507 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
15508 Likewise.
15509 * src/state.c (transitions_to): Likewise.
15510 * src/state.h: Likewise.
15511 * src/tables.c (symbol_number_to_vector_number): Likewise.
15512
15513 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
15514 char * var.
15515
15516 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
15517 var.
15518
15519 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
15520 var.
15521
15522 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
15523 Use str, not s, for char * var. Use ch, not c, for character var.
15524 Use size for size var.
15525
15526 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
15527 char * var.
15528 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for

15531
15532 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
15533 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
15534 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
15535 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
15536 param to have same name as that of enum, so that we don't use
15537 "s" to stand for a non-state.
15538
15539 2003-02-02 Akim Demaille <akim@epita.fr>
15540
15541 * src/scan-skel.l: Scan more than one inert character per yylex
15542 invocation.
15543
15544 2003-02-01 Paul Eggert <eggert@twinsun.com>
15545
15546 Version 1.875a.
15547
15548 * po/LINGUAS: Add ms.
15549
15550 2003-01-30 Akim Demaille <akim@epita.fr>
15551
15552 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
15553
15554 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15555
15556 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
15557 of $1.
15558
15559 Changes in response to error report by S. Eken: GLR mode does not
15560 handle negative $ indices or $ indices in embedded rules correctly.
15561 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
15562
15563 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
15564 (b4_rhs_location): Ditto.
15565 (yyfill): New function to copy from stack tree into array
15566 incrementally.
15567 (yyuserAction): Modify to allow incremental move of semantic values
15568 to rhs array when in GLR mode.
15569 Define YYFILL to use in user-defined actions to fill semantic array
15570 as needed.
15571 Remove dummy use of yystack, as there is now a guaranteed use.
15572 (yydoAction): Modify to allow incremental move of semantic values
15573 to rhs array when in GLR mode.
15574 (yyresolveAction): Ditto.
15575 (yyglrShiftDefer): Update comment.
15576 (yyresolveStates): Use X == NULL for pointers, not !X.
15577 (yyglrReduce): Ditto.
15578 (yydoAction): Ditto
15579
15580 * tests/glr-regr1.at: Rename to ...
15581 * tests/glr-regression.at: Add new regression test for the problems
15582 described above (adapted from S. Eken).
15583 Update copyright notice.
15584 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
15585 * tests/Makefile.am: Ditto.
15586
15587 2003-01-28 Paul Eggert <eggert@twinsun.com>
15588
15589 * data/lalr1.cc: Do not use @output_header_name@ unless
15590 b4_defines_flag is set. This fixes two bugs reported by
15591 Tim Van Holder in
15592 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
15593 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
15594
15595 2003-01-21 Paul Eggert <eggert@twinsun.com>
15596
15597 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
15598 we don't need to worry about yyerrlab1 being reported as an
15599 "unused label" by non-GCC C compilers. The downside is that if
15600 locations are used then a couple of statements are duplicated each
15601 time YYERROR is invoked, but the upside is that the warnings
15602 should vanish.
15603 (yyerrlab1): Move code to YERROR.
15604 (yyerrlab2): Remove. Change uses back to yyerrlab1.
15605 This reverts some of the 2002-12-27 change.
15606
15607 2003-01-17 Paul Eggert <eggert@twinsun.com>
15608
15609 * src/output.c (symbol_printers_output): Fix typo that led
15610 to core dump. Problem reported by Antonio Rus in
15611 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
15612
15613 2003-01-13 Akim Demaille <akim@epita.fr>,
15614 Quoc Peyrot <chojin@lrde.epita.fr>,
15615 Robert Anisko <anisko_r@lrde.epita.fr>
15616
15617 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
15618 when the stacks contain one element, as the loop would otherwise
15619 free the last state, and then use the top state (the one we just
15620 popped). This means that the initial elements will not be freed
15621 explicitly, as is the case in yacc.c; it is not a problem, as
15622 these elements have fake values.
15623
15624 2003-01-11 Paul Eggert <eggert@twinsun.com>
15625
15626 * NEWS: %expect-violations are now just warnings, reverting
15627 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
15628 bootstrapping problem reported by Matthias Klose; see
15629 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
15630 * src/conflicts.c (conflicts_print): Likewise.
15631 * tests/conflicts.at (%expect not enough, %expect too much,
15632 %expect with reduce conflicts): Likewise.
15633 * doc/bison.texinfo (Expect Decl): Document this. Also mention
15634 that the warning is enabled if the number of conflicts changes
15635 (not necessarily increases).
15636
15637 * src/getargs.c (version): Update copyright year.
15638
15639 2003-01-09 Akim Demaille <akim@epita.fr>
15640
15641 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
15642
15643 2003-01-08 Paul Eggert <eggert@twinsun.com>
15644
15645 * Makefile.maint (WGETFLAGS):
15646 New macro, containing "-C off" to disable proxy caches.
15647 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
15648 (rel-check): Use $(WGET) instead of wget.
15649
15650 2003-01-06 Paul Eggert <eggert@twinsun.com>
15651
15652 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
15653 the GLR paper of Scott, Johnstone and Hussain.
15654
15655 2003-01-04 Paul Eggert <eggert@twinsun.com>
15656
15657 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
15658 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
15659 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
15660 (EXTRA_LIBRARIES): New var, for liby.a.
15661 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
15662 (EXTRA_SCRIPTS): New var, for yacc.
15663
15664 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
15665 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
15666 Problem reported by Nelson H. F. Beebe.
15667
15668 2003-01-03 Paul Eggert <eggert@twinsun.com>
15669
15670 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
15671 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
15672 when compiling Bison 1.875's `bitset bset = obstack_alloc
15673 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
15674
15675 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
15676 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
15677 grow to a huge size with typical invocation.
15678
15679 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
15680 Use the pattern recommended by Autoconf 2.57, except also protect
15681 against double-definition.
15682 * src/system.h: Likewise.
15683 Portability issues reported by Nelson H. F. Beebe.
15684
15685 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
15686 All uses changed. Provide a definition in both C and C++.
15687 (yytrue, yyfalse): Define even if defined (__cplusplus).
15688
15689 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
15690 Reported by Nelson H. F. Beebe.
15691
15692 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
15693
15694 2003-01-02 Paul Eggert <eggert@twinsun.com>
15695
15696 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
15697 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
15698 Bug reported by Nelson H. F. Beebe.
15699
15700 2003-01-01 Paul Eggert <eggert@twinsun.com>
15701
15702 * Version 1.875.
15703
15704 2002-12-30 Paul Eggert <eggert@twinsun.com>
15705
15706 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
15707 Moved here from...
15708 (<INITIAL>","): Here. This causes stray "," to be treated
15709 more uniformly.
15710
15711 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
15712 last brace in braced code when not in Yacc mode, for compatibility
15713 with Bison 1.35. This resurrects the 2001-12-15 patch to
15714 src/reader.c.
15715
15716 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
15717 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
15718
15719 2002-12-28 Paul Eggert <eggert@twinsun.com>
15720
15721 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
15722 that of SYM's type. This fixes Debian bug 168069, reported by
15723 Thomas Olsson.
15724
15725 2002-12-28 Paul Eggert <eggert@twinsun.com>
15726
15727 Version 1.75f.
15728
15729 Switch back to the Yacc style of conflict reports, undoing some
15730 of the 2002-07-30 change.
15731 * doc/bison.texinfo (Understanding): Use Yacc style for
15732 conflict reports. Also, use new way of locating rules.
15733 * src/conflicts.c (conflict_report):
15734 Renamed from conflict_report_yacc, removing the old
15735 'conflict_report'. Translate the entire conflict report at once,
15736 so that we don't assume that "," has the same interpretation in
15737 all languages.
15738 (conflicts_output): Use Yacc-style conflict report for each state,
15739 instead of our more-complicated style.
15740 (conflicts_print): Use Yacc-style conflict report, except print
15741 the input file name when not emulating Yacc.
15742 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
15743 Conflicted Reduction, %expect not enough, %expect too much,
15744 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
15745 * tests/existing.at (GNU Cim Grammar): Likewise.
15746 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
15747
15748 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
15749 fatal): Don't invoke fflush; it's not needed and it might even be
15750 harmful for stdout, as stdout might not be open.
15751 * src/reduce.c (reduce_print): Likewise.
15752
15753 2002-12-27 Paul Eggert <eggert@twinsun.com>
15754
15755 Fix a bug where error locations were not being recorded correctly.
15756 This problem was originally reported by Paul Hilfinger in
15757 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
15758
15759 * data/yacc.c (yyparse): New local var yylerrsp, to record the
15760 top of the location stack's error locations.
15761 (yyerrlab): Set it. When discarding a token, push its location
15762 onto yylerrsp so that we don't lose track of the error's end.
15763 (yyerrlab1): Now is only the target of YYERROR, so that we can
15764 properly record the location of the action that failed. For GCC
15765 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
15766 GCC warning about yyerrlab1 being unused if YYERROR is unused.
15767 (yyerrlab2): New label, which yyerrlab now falls through to.
15768 Compute the error's location by applying YYLLOC_DEFAULT to
15769 the locations of all the symbols that went into the error.
15770 * doc/bison.texinfo (Location Default Action): Mention that
15771 YYLLOC_DEFAULT is also invoked for syntax errors.
15772 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
15773 Error locations include the locations of all the tokens that were
15774 discarded, not just the last token.
15775
15776 2002-12-26 Paul Eggert <eggert@twinsun.com>
15777
15778 * src/files.c: Include quote.h.
15779 (compute_output_file_names): Warn if we detect conflicting
15780 outputs to the same file. This should catch the misunderstanding
15781 exemplified by Debian Bug 165349, reported by Bruce Stephens..
15782
15783 * src/conflicts.c (conflicts_print): If the user specifies
15784 "%expect N", report an error if there are any reduce/reduce
15785 conflicts. This is what the manual says should happen.
15786 This fixes Debian bug 130890, reported by Anthony DeRobertis.
15787 * tests/conflicts.at (%expect with reduce conflicts): New test.
15788
15789 Don't use m4_include on relative file names, as it doesn't work as
15790 desired if there happens to be a file with that name under ".".
15791
15792 * m4sugar/version.m4: Remove; it was included but it wasn't used.
15793 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
15794 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
15795 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
15796 * src/output.c (output_skeleton): Use full path names when
15797 specifying a file to include; don't rely on include path, as
15798 it's unreliable when the working file contains a file with
15799 that name.
15800
15801 2002-12-25 Paul Eggert <eggert@twinsun.com>
15802
15803 Remove obsolete references to bison.simple and bison.hairy.
15804 Problem mentioned by Aubin Mahe in
15805 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
15806 * data/glr.c: Comment fix.
15807 * doc/bison.1: Remove references. Also, mention "yacc".
15808
15809 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
15810 with -g option.
15811
15812 * src/parse-gram.y (declaration): Use enum "report_states" rather
15813 than its numeric value 1.
15814
15815 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
15816 opening a new one. This fixes Debian bug 165349, reported by
15817 Bruce Stephens.
15818
15819 2002-12-24 Paul Eggert <eggert@twinsun.com>
15820
15821 Version 1.75e.
15822
15823 * Makefile.maint (cvs-update): Don't assume that the shell
15824 supports $(...), as Solaris sh doesn't.
15825
15826 * src/parse-gram.y (lloc_default): Remove test for empty
15827 nonterminals at the end, since it didn't change the result.
15828
15829 2002-12-24 Paul Eggert <eggert@twinsun.com>
15830
15831 If the user does not define YYSTYPE as a macro, Bison now declares it
15832 using typedef instead of defining it as a macro. POSIX requires this.
15833 For consistency, YYLTYPE is also declared instead of defined.
15834
15835 %union directives can now have a tag before the `{', e.g., the
15836 directive `%union foo {...}' now generates the C code
15837 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
15838 The default union tag is `YYSTYPE', for compatibility with Solaris 9
15839 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
15840 instead of `yyltype'.
15841
15842 `yystype' and `yyltype' are now obsolescent macros instead of being
15843 typedefs or tags; they are no longer documented and will be
15844 withdrawn in a future release.
15845
15846 * data/glr.c (b4_location_type): Remove.
15847 (YYSTYPE): Renamed from yystype.
15848 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
15849 (struct YYLTYPE): Renamed from struct yyltype.
15850 (YYLTYPE): Renamed from yyltype.
15851 (yyltype, yystype): New (and obsolescent) macros,
15852 for backward compatibility.
15853 * data/yacc.c: Likewise.
15854
15855 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
15856 does not specify a union tag. This is for compatibility with
15857 Solaris 9 yacc.
15858
15859 * src/parse-gram.y (add_param): 2nd arg is now char * not char
15860 const *, since it is now modified by stripping surrounding { }.
15861 (current_braced_code): Remove.
15862 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
15863 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
15864 trailing " {...}". Now of type <chars>.
15865 (grammar_declaration): Adjust to bundled tokens.
15866 (code_content): Remove; stripping is now done by add_param.
15867 (print_token_value): Print contents of bundled tokens.
15868 (token_name): New function.
15869
15870 * src/reader.h (braced_code, current_braced_code): Remove.
15871 (token_name): New decl.
15872
15873 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
15874 token_type, not braced_code code_kind. All uses changed.
15875 (SC_PRE_CODE): New state, for scanning after a keyword that
15876 has (or usually has) an immediately-following braced code.
15877 (token_type): New local var, to keep track of which token type
15878 to return when scanning braced code.
15879 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
15880 <INITIAL>"%parse-param", <INITIAL>"%printer",
15881 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
15882 instead of returning a token type immediately.
15883 (<INITIAL>"{"): Set token type.
15884 (<SC_BRACED_CODE>"}"): Use it.
15885 (handle_action_dollar, handle_action_at): Now returns bool
15886 indicating success. Fail if ! current_rule; this prevents a core dump.
15887 (handle_symbol_code_dollar, handle_symbol_code_at):
15888 Remove; merge body into caller.
15889 (handle_dollar, handle_at): Complain in invalid contexts.
15890
15891 * NEWS, doc/bison.texinfo: Document the above.
15892 * NEWS: Fix years and program names in copyright notice.
15893
15894 2002-12-17 Paul Eggert <eggert@twinsun.com>
15895
15896 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
15897 Reporting, Table of Symbols): Omit mentions of %lex-param and
15898 %parse-param from the documentation for now.
15899
15900 2002-12-15 Paul Eggert <eggert@twinsun.com>
15901
15902 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
15903 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
15904 lookahead symbol, and which sets yychar in parser actions) and it
15905 disagreed with the Bison documentation. Bug
15906 reported by Andrew Walrond.
15907
15908 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
15909 as the caller now does that.
15910 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
15911 (YYEMPTY): Parenthesize right hand side, since others use it.
15912 (yyparse): Don't assume that our generated code is the only code
15913 that sets yychar.
15914
15915 2002-12-13 Paul Eggert <eggert@twinsun.com>
15916
15917 Version 1.75d.
15918
15919 POSIX requires a "yacc" command.
15920 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
15921 (MOSTLYCLEANFILES): Add yacc.
15922 (yacc): New rule.
15923 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
15924 as an alias for bison y.
15925
15926 * po/LINGUAS: Add da.
15927
15928 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
15929 problem with latest <getopt.h>.
15930 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
15931
15932 * doc/fdl.texi: Upgrade to 1.2.
15933 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
15934 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
15935 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
15936 gnulib.
15937 * config/install-sh: Sync with autotools.
15938
15939 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
15940 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
15941 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
15942 locations are requested.
15943 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
15944 locations are requested.
15945
15946 2002-12-12 Paul Eggert <eggert@twinsun.com>
15947
15948 Remove unportable casts and storage allocation tricks.
15949 While we're at it, remove almost all casts, since they
15950 usually aren't needed and are a sign of trouble.
15951
15952 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
15953
15954 * src/derives.c (derives_compute): Do not subtract NTOKENS from
15955 the pointer DSET returned by malloc; this isn't portable.
15956 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
15957 Similarly for DERIVES.
15958 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
15959 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
15960 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
15961
15962 * src/derives.c (derives_compute): Do not bother invoking
15963 int_of_rule_number, since rule numbers are integers.
15964
15965 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
15966 rather than XMALLOC (char, N).
15967
15968 * src/files.c (filename_split): Rewrite to avoid cast.
15969
15970 * src/gram.h (symbol_number_as_item_number,
15971 item_number_as_symbol_number, rule_number_as_item_number,
15972 item_number_as_rule_number):
15973 Now inline functions rather than macros, to avoid casts.
15974 * src/state.h (state_number_as_int): Likewise.
15975 * src/tables.c (state_number_to_vector_number,
15976 symbol_number_to_vector_number): Likewise.
15977
15978 * src/gram.h (int_of_rule_number): Remove; no longer used.
15979
15980 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
15981 since the resulting storage is always stored into.
15982
15983 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
15984 where it's needed.
15985
15986 * src/muscle_tab.c (muscle_m4_output):
15987 Now inline. Return bool, not int.
15988 * src/state.c (state_compare): Likewise.
15989 * src/symtab.c (symbol_check_defined,
15990 symbol_check_alias_consistency, symbol_pack, symbol_translation,
15991 hash_compare_symbol, hash_symbol):
15992 Likewise.
15993 * src/uniqstr.c (uniqstr_print): Likewise.
15994 * src/muscle_tab.c (muscle_m4_output_processor):
15995 New function, to avoid casts.
15996 * src/state.c (state_comparator, stage_hasher): Likewise.
15997 * src/symtab.c (symbol_check_defined_processor,
15998 symbol_check_alias_consistency_processor, symbol_pack_processor,
15999 symbol_translation_processor, hash_symbol_comparator,
16000 hash_symbol_hasher): Likewise.
16001 * src/uniqstr.c (uniqstr_print_processor): Likewise.
16002 * src/muscle_tab.c (muscles_m4_output):
16003 Use new functions instead of casting old functions unportably.
16004 * src/state.c (state_hash_new): Likewise.
16005 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
16006 symbols_token_translations_init):
16007 Likewise.
16008 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
16009
16010 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
16011 var instead of casting to long, to avoid casts.
16012 (prepare_states): Use MALLOC rather than alloca, so that we don't
16013 have to worry about alloca.
16014 * src/state.c (state_hash_lookup): Likewise.
16015
16016 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
16017 local var instead of casting to unsigned char, to avoid casts.
16018
16019 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
16020 STATE_ALLOC): Remove.
16021 (transitions_new, errs_new, reductions_new, state_new): Use malloc
16022 rather than calloc, and use offsetof to avoid allocating slightly
16023 too much storage.
16024 (state_new): Initialize all members.
16025
16026 * src/state.c (state_hash): Use unsigned accumulator, not signed.
16027
16028 * src/symtab.c (symbol_free): Remove; unused.
16029 (symbol_get): Remove cast in lhs of assignment.
16030 (symbols_do): Now static. Accept generic arguments, not
16031 hashing-related ones.
16032
16033 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
16034 (symbol_processor): Remove.
16035 (symbols_do): Remove decl; now static.
16036
16037 * src/system.h (alloca): Remove; decl no longer needed.
16038 (<stddef.h>): Include, for offsetof.
16039 (<inttypes.>, <stdint.h>): Include if available.
16040 (uintptr_t): New type, if system lacks it.
16041 (CALLOC, MALLOC, REALLOC): New macros.
16042 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
16043 new macros.
16044
16045 * src/tables.c (table_size): Now int, to pacify GCC.
16046 (table_grow, table_ninf_remap): Use signed table size.
16047 (save_row): Don't bother initializing locals when not needed.
16048 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
16049 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
16050
16051 * src/vcg.h: Correct misspellings.
16052
16053 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
16054
16055
16056 * src/getargs.c (getargs): Don't assume EOF == -1.
16057
16058 2002-12-09 Paul Eggert <eggert@twinsun.com>
16059
16060 Change identifier spellings to avoid collisions with names
16061 that are reserved by POSIX.
16062
16063 Don't use names ending in _t, since POSIX reserves them.
16064 For consistency, remove _e and _s endings -- they're weren't
16065 needed to remove ambiguity. All uses changed.
16066 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
16067 turn was just renamed from struniq_t.
16068 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
16069 which in turn was just renamed from struniq_processor_t.
16070 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

16102 (struct state): Renamed from struct state_s.
16103 (state): Renamed from state_t.
16104 (transitions): Renamed from transitions_t. Unused (and
16105 misspelled) transtion_s tag removed.
16106 (errs): Renamed from errs_t. Unused errs_s tag removed.
16107 (reductions): Renamed from reductions_t. Unused tag
16108 reductions_s removed.
16109 * src/symlist.h (symbol_list): Renamed from symbol_list_t.

16141 value_t_as_yystype -> value_as_yystype.
16142
16143 Don't include <errno.h> in the mainstream code, since it
16144 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
16145 * lib/get-errno.c, lib/get-errno.h: New files.
16146 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
16147 get-errno.c.
16148 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
16149 * src/output.c (output_skeleton): Likewise.
16150 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
16151 instead of errno.
16152 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):
16153 Likewise.
16154 (handle_action_dollar, handle_action_at): Likewise.

16156 (TAB_EXT): Renamed from EXT_TAB.
16157 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
16158
16159 Avoid str[a-z]*, since <string.h> reserves that name space.
16160 Change all instances of "struniq" in names to "uniqstr", and
16161 likewise for "STRUNIQ" and "UNIQSTR".
16162 * src/uniqstr.c: Renamed from src/struniq.c.
16163 * src/uniqstr.h: Renamed from src/struniq.h.
16164 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
16165 * src/files.c (strsuffix): Remove; unused.

16167 * src/files.h (strsuffix, stringappend): Remove; unused.
16168 * src/parse-gram.y (<chars>): Renamed from <string>.
16169 (<uniqstr>): Renamed from <struniq>.
16170 * src/scan-gram.l (obstack_for_string): Renamed from string_obstack.
16171 * src/vcg.h (struct node_s.expand): Renamed from struct node_s.stretch.
16172 (struct graph_s.expand): Renamed from struct graph_s.stretch.
16173 * src/vcg_defaults.h (G_EXPAND): Renamed from G_STRETCH.
16174 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
16175 (N_EXPAND): Renamed from N_STRETCH.
16176
16177 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
16178 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
16179 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
16180 Remove; unused.
16181 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
16182 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
16183 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.

16186 (BASE_MINIMUM): Renamed from BASE_MIN.
16187 (ACTION_MAX): Remove; unused.
16188 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
16189 Unnecessary casts removed from above defines.
16190
16191
16192 Fix misspelling in names.
16193 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
16194 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
16195 G_NODE_ALIGNEMENT.
16196
16197
16198 * lib/timevar.c (timevar_report): Renamed from time_report,
16199 for consistency with other names.
16200 * lib/timevar.h (timevar_report): New decl.
16201 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
16202
16203
16204 Sort include-file uses.
16205
16206 Reorder all include files under src to be in the order "system.h".
16207 then the ../lib include files in angle brackets (alphabetized),
16208 then the . include files in double-quotes (alphabetized). Fix
16209 dependency breakages encountered in this process, as follows:
16210 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
16211 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
16212 * src/state.h: Include "symtab.h".
16213
16214 2002-12-08 Paul Eggert <eggert@twinsun.com>
16215
16216 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
16217 since this causes problems when __file__ contains character
16218 sequences like "@" that are treated specially by src/scan-skel.l.
16219 Instead, just use the file's basename. This fixes the bug
16220 reported by Martin Mokrejs in
16221 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
16222
16223 2002-12-06 Paul Eggert <eggert@twinsun.com>
16224
16225 Add support for rules that do not have trailing semicolons, as
16226 POSIX requires. Improve the quality of locations in Bison
16227 diagnostics.
16228
16229 * src/location.c: Include <quotearg.h>.
16230 (empty_location): Now const.
16231 (location_print): New function. Follow the recommendation of the
16232 GNU Coding Standards for locations that span file boundaries.
16233 * src/location.h: Do not include <quotearg.h>; no longer needed.
16234 (boundary): New type.
16235 (location_t): Use it. This allows locations to span file boundaries.
16236 All member uses changed: file -> start.file or end.file (as needed),
16237 first_line -> start.line, first_column -> start.column,
16238 last_line -> end.line, last_column -> end.column.
16239 (equal_boundaries): New function.
16240 (LOCATION_RESET, LOCATION_STEP): Remove.
16241 (LOCATION_PRINT): Remove. All callers changed to use location_print.
16242 (empty_location): Now const.
16243 (location_print): New decl.
16244 * src/parse-gram.y (lloc_default): New function, which handles
16245 empty locations more accurately.
16246 (YYLLOC_DEFAULT): Use it.
16247 (%token COLON): Remove.
16248 (%token ID_COLON): New token.
16249 (rules): Use it.
16250 (declarations, rules): Remove trailing semicolon.
16251 (declaration, rules_or_grammar_declaration):
16252 Allow empty (";") declaration.
16253 (symbol_def): Remove empty actions; no longer needed.
16254 (rules_or_grammar_declaration): Remove trailing semicolon.
16255 (semi_colon.opt): Remove.
16256 * src/reader.h: Include location.h.
16257 (scanner_cursor): New decl.
16258 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
16259 rolling our own.
16260 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
16261 of *loc.
16262 (STEP): Remove. No longer needed, now that adjust_location does
16263 the work. All uses removed.
16264 (scanner_cursor): New var.
16265 (adjust_location): Renamed from extend_location. It now sets
16266 *loc and adjusts the scanner cursor. All uses changed.
16267 Don't bother testing for CR.
16268 (handle_syncline): Remove location arg; now updates scanner cursor.
16269 All callers changed.
16270 (unexpected_end_of_file): Now accepts start boundary of token or
16271 comment, not location. All callers changed. Update scanner cursor,
16272 not the location.
16273 (SC_AFTER_IDENTIFIER): New state.
16274 (context_state): Renamed from c_context. All uses changed.
16275 (id_loc, code_start, token_start): New local vars.
16276 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
16277 processing of Yacc white space and equivalents here.
16278 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
16279 instead of returning ID immediately, since we need to search for
16280 a subsequent colon.
16281 (<INITIAL>"'", "\""): Save token_start.
16282 (<INITIAL>"%{", "{", "%%"): Save code_start.
16283 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
16284 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
16285 BEGIN context_state at end, not INITIAL.
16286 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
16287 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
16288 Return correct token start.
16289 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
16290 the start of a character, string or multiline comment is found.
16291 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
16292 Reduction): Adjust reported locations to match the more-precise
16293 results now expected.
16294 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
16295 * tests/reduce.at (Useless Rules, Reduced Automaton,
16296 Underivable Rules): Likewise.
16297 * tests/regression.at (Invalid inputs): No longer `expecting ";"
16298 or "|"' now that so many other tokens are allowed by the new grammar.
16299
16300 * src/complain.h (current_file): Remove duplicate decl;
16301 current_file is now owned by files.h.
16302 * src/complain.c, src/scan-gram.l: Include files.h.
16303
16304 2002-12-06 Paul Eggert <eggert@twinsun.com>
16305
16306 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
16307 promotes to int; it might be unsigned int.
16308 * data/yacc.c (yy_reduce_print): Likewise.
16309
16310 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
16311 be #defined in the prologue, not in the Bison declarations.
16312 This fixes Debian Bug 102878, reported by Shaul Karl.
16313
16314 2002-12-02 Paul Eggert <eggert@twinsun.com>
16315
16316 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
16317 * lib/strtoul.c: New file, from gnulib.
16318 This fixes a porting bug reported by Peter Klein in
16319 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
16320
16321 2002-11-30 Paul Eggert <eggert@twinsun.com>
16322
16323 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
16324 and put only a forward declaration in the prologue. This is for
16325 consistency with the other scanner helper functions.
16326
16327 Type clashes now generate warnings, not errors, since it
16328 appears that POSIX may allow some grammars with type clashes.
16329 * src/reader.c (grammar_current_rule_check): Warn about
16330 type clashes instead of complaining.
16331 * tests/input.at (Type Clashes): Expect warnings, not complaints.
16332
16333 Add Yacc library, since POSIX requires it.
16334 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
16335 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
16336 * lib/main.c, lib/yyerror.c: New files.
16337
16338 gram_error can be static; it need not be extern.
16339 * src/reader.h (gram_error): Remove decl.
16340 * src/parse-gram.y (gram_error): Now static. Add static decl.
16341 (print_token_value): Omit parameter names from forward decl,
16342 for consistency.
16343
16344 2002-11-29 Paul Eggert <eggert@twinsun.com>
16345
16346 * doc/bison.texinfo: Emphasize that yylex and yyerror must
16347 be declared before being used. E.g., one should typically
16348 declare them in the prologue. Use GNU coding style in examples.
16349 Put "const" consistently after the type it modifies. Mention
16350 that C99 supports "inline". Mention that yyerror traditionally
16351 returns "int".
16352
16353 %parse-param and %lex-param now take just one argument, the
16354 declaration; the argument name is deduced from the declaration.
16355
16356 * doc/bison.texinfo (Parser Function, Pure Calling, Error
16357 Reporting, Table of Symbols): Document this.
16358 * src/parse-gram.y (add_param): New function.
16359 (COMMA): Remove.
16360 (declaration): Implement new rule for %parse-param and %lex-param.
16361 * src/scan-gram.l: "," now elicits a warning, rather than being
16362 a token; this is more compatible with byacc.
16363 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
16364
16365 2002-11-27 Paul Eggert <eggert@twinsun.com>
16366
16367 Rename identifiers to avoid real and potential collisions.
16368
16369 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
16370 to avoid collision with lex macro described by Bruce Lilly in
16371 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
16372 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
16373 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
16374 * src/parse-gram.y (print_token_value): Renamed from yyprint.
16375 All uses changed.
16376 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
16377 The name "yycontrol" violates the name space rules, and this stuff
16378 wasn't being used anyway.
16379 (input): Remove action; this stuff wasn't being used.
16380 (gram_error): Rename local variable yylloc -> loc.
16381 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
16382 (YY_DECL): Don't use "yy" at start of local variables.
16383 All uses changed, e.g., yylloc -> loc.
16384 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
16385 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
16386 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
16387 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
16388
16389 * src/parse-gram.y (gram_error): loc is now const *.
16390 * src/reader.h (gram_error): Likewise.
16391
16392 2002-11-24 Paul Eggert <eggert@twinsun.com>
16393
16394 Version 1.75c.
16395
16396 * tests/actions.at (Actions after errors): Use an output format
16397 more similar to that of the Printers and Destructors test.
16398 Test the position of the ';' token too.
16399 (Printers and Destructors): Likewise.
16400 (Printers and Destructors: %glr-parser): Remove for now, to avoid
16401 unnecessarily alarming people when the test fails.
16402
16403 * data/yacc.c (yyerrlab1): Move this label down, so that the
16404 parser does not discard the lookahead token if the user code
16405 invokes YYERROR. This change is required for POSIX conformance.
16406
16407 * lib/error.c: Sync with gnulib.
16408
16409 2002-11-22 Paul Eggert <eggert@twinsun.com>
16410
16411 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
16412 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
16413 * lib/xmalloc.c: Likewise.
16414
16415 2002-11-20 Paul Eggert <eggert@twinsun.com>
16416
16417 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
16418
16419 2002-11-20 Paul Eggert <eggert@twinsun.com>
16420
16421 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
16422 should use `if (! x) abort ();' rather than `assert (x);', and
16423 anyway it's one less thing to worry about configuring.
16424
16425 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
16426 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
16427 and replace all instances of assert with abort.
16428 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
16429 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
16430
16431 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
16432 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
16433 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
16434 hash_find_entry, hash_rehash, hash_insert): Likewise.
16435 * src/conflicts.c (resolve_sr_conflict): Likewise.
16436 * src/lalr.c (set_goto_map, map_goto): Likewise.
16437 * src/nullable.c (nullable_compute): Likewise.
16438 * src/output.c (prepare_rules, token_definitions_output): Likewise.
16439 * src/reader.c (packgram, reader): Likewise.
16440 * src/state.c (state_new, state_free, state_transitions_set,
16441 state_reduction_find): Likewise.
16442 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
16443 symbol_pack): Likewise.
16444 * src/tables.c (conflict_row, pack_vector): Likewise.
16445 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
16446 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
16447 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
16448 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
16449
16450 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
16451 (ARGMATCH_CONSTRAINT): New macro.
16452 (ARGMATCH_ASSERT): Use it.
16453
16454 * src/system.h (verify): New macro.
16455 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
16456 rather than assert.
16457 * src/tables.c (tables_generate): Likewise.
16458
16459 * src/struniq.c (struniq_assert): Now returns void, and aborts
16460 if the assertion is false.
16461 (struniq_assert_p): Remove.
16462 * src/struniq.h: Likewise.
16463
16464 2002-11-18 Paul Eggert <eggert@twinsun.com>
16465
16466 * data/glr.c (yygetLRActions): Replace `yyindex' with
16467 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
16468 This fixes the regression with Sun ONE Studio 7 cc that I reported in
16469 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
16470
16471 2002-11-18 Akim Demaille <akim@epita.fr>
16472
16473 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
16474 space.
16475 From Tim Van Holder.
16476
16477 2002-11-17 Paul Eggert <eggert@twinsun.com>
16478
16479 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
16480 to "SyntaxError" for consistency with my 2002-11-15 change.
16481
16482 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
16483 not define to {}, since this breaks the common use of `YYDPRINTF
16484 ((...));' if a single statement is desired (e.g. before `else').
16485 Work around GCC warnings by surrounding corresponding calls with
16486 {} if needed.
16487 (yyhasResolvedValue): Remove unused function.
16488 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
16489 loop body.
16490 (yyreportSyntaxError): Renamed from yyreportParseError.
16491 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
16492 All uses changed.
16493 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
16494 extern when possible. Remove unused initializations.
16495
16496 2002-11-16 Akim Demaille <akim@epita.fr>
16497
16498 Augment the similarity between GLR and LALR traces.
16499
16500 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
16501 (YY_REDUCE_PRINT): New.
16502 (yyparse): Use them.
16503 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
16504 YYDPRINT here.
16505 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
16506 state reached after the reduction/recovery, since...
16507 (yyparse, yyprocessOneStack): Report the state we are entering in.
16508
16509 2002-11-16 Akim Demaille <akim@epita.fr>
16510
16511 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
16512 Add support for --trace=skeleton.
16513 * src/scan-skel.l: %option debug.
16514 Scan strings of non-@ or \n instead of character by character.
16515 (scan_skel): Handle trace_skeleton.
16516 (QPUTS): New.
16517 (@output_parser_name@, @output_header_name@): ``Restore'' their
16518 support (used to be M4 macros).
16519 * data/yacc.c: Quote larger chunks, a la glr.c.
16520 * data/lalr1.cc: Likewise.
16521 The header guards are no longer available, so use some other
16522 string than `YYLSP_NEEDED'.
16523
16524 2002-11-16 Akim Demaille <akim@epita.fr>
16525
16526 Make the ``Printers and Destructors'' test more verbose, taking
16527 `yacc.c''s behavior as (possibly wrong) reference.
16528
16529 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
16530 instead of fprint on stdout.
16531 Set and report the last_line of the symbols.
16532 Consistently display values and locations.
16533
16534 2002-11-16 Paul Eggert <eggert@twinsun.com>
16535
16536 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
16537
16538 2002-11-15 Paul Eggert <eggert@twinsun.com>
16539
16540 * tests/actions.at (Actions after errors): New test case.
16541
16542 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
16543 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
16544 tests/action.at, tests/calc.at, tests/conflicts.at,
16545 tests/cxx-type.at, tests/regression.at:
16546 "parse error" -> "syntax error" for POSIX compatibility.
16547 "parsing stack overflow..." -> "parser stack overflow" so
16548 that code matches Bison documentation.
16549
16550 2002-11-15 Akim Demaille <akim@epita.fr>
16551
16552 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
16553 take two BRACED_CODE, not two string_content.
16554 Free the scanner's obstack when we are done.
16555 (code_content): New.
16556 * tests/calc.at: Adjust.
16557 * doc/bison.texinfo: Adjust.
16558 Also, make sure to include the `,' for these declarations.
16559
16560 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
16561
16562 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
16563 definition; avoids potential autoreconf problems.
16564
16565 2002-11-15 Akim Demaille <akim@epita.fr>
16566
16567 Always check the value returned by yyparse.
16568
16569 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
16570 returned by yyparse.
16571 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
16572 Adjust calls.
16573 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
16574 returned by yyparse.
16575
16576 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16577
16578 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
16579 on input.at test.
16580
16581 2002-11-14 Paul Eggert <eggert@twinsun.com>
16582
16583 * src/output.c (output_skeleton): Call xfopen instead of
16584 duplicating xfopen's body.
16585
16586 Fix bugs reported by Nelson H. F. Beebe in
16587 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
16588
16589 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
16590 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
16591 Group compiler. Instead, use "$CC -E bar.c". Include the .h
16592 file twice in the grammar, as an extra check.
16593
16594 * tests/input.at (Torturing the Scanner): Surround the
16595 backslash-newline tests with "#if 0", to make it less likely that
16596 we'll run into compiler bugs. Bring back solitary \ inside
16597 comment, but add a closing comment to work around HP C bug. Don't
16598 test backslash-newline in C character constant.
16599
16600 2002-11-14 Akim Demaille <akim@epita.fr>
16601
16602 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
16603 status of the compiler.
16604 Calling `exit 1' is no longer needed.
16605 Reported by Nelson H. F. Beebe.
16606
16607 2002-11-14 Akim Demaille <akim@epita.fr>
16608
16609 * tests/atlocal.in (CPPFLAGS): We have config.h.
16610 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
16611 New.
16612 * tests/actions.at, tests/calc.at, tests/conflicts.at,
16613 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
16614 * tests/regression.at, tests/torture.at: Use them for all the
16615 grammars that are to be compiled.
16616 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
16617 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
16618 * doc/bison.texinfo (GLR Parsers): Document `inline'.
16619
16620 2002-11-14 Akim Demaille <akim@epita.fr>
16621
16622 * doc/bison.texinfo: Various formatting changes (alignments in
16623 samples, additional @group/@end group, GCS in samples.
16624 Use @deffn instead of simple @table to define the directives,
16625 macros, variables etc.
16626
16627 2002-11-13 Paul Eggert <eggert@twinsun.com>
16628
16629 Fix some bugs reported by Albert Chin-A-Young in
16630 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
16631
16632 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
16633 -o c"; the HP C compiler chatters during compilation.
16634 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
16635 * tests/headers.at (export YYLTYPE): Likewise.
16636
16637 * tests/input.at (Torturing the Scanner): Remove lines containing
16638 solitary backslashes, as they tickle a bug in the HP C compiler.
16639
16640 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
16641 comments, since they're not portable. Use GNU coding style.
16642
16643 2002-11-13 Akim Demaille <akim@epita.fr>
16644
16645 * data/yacc.c: Leave bigger chunks of quoted text.
16646 (YYDSYMPRINTF): New.
16647 Use it to report symbol activities.
16648 * data/glr.c (YYDSYMPRINTF): New.
16649 Use it.
16650
16651 2002-11-12 Paul Eggert <eggert@twinsun.com>
16652
16653 Version 1.75b.
16654
16655 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
16656 (yyglrReduce): Return yyok, not 0.
16657 This should avoid the enumerated-type warnings reported
16658 by Nelson H. F. Beebe in
16659 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
16660
16661 * lib/bbitset.h (BITSET_INLINE): Remove.
16662 * lib/bitset.h [! BITSET_INLINE]: Remove.
16663 (bitset_set, bitset_reset, bitset_test): Rename local vars
16664 to avoid shadowing warnings by GCC.
16665
16666 * data/glr.c (inline): Remove #define. It's the user's
16667 responsibility to #define it away, just like 'const'.
16668 This fixes one of the bugs reported by Nelson H. F. Beebe in
16669 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
16670
16671 * Makefile.maint (po-check): Scan .l and .y files instead of the
16672 .c and the .h files that they generate. This fixes the bug
16673 reported by Tim Van Holder in:
16674 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
16675 Look for N_ as well as for _. Try to avoid matching #define for
16676 N_ and _.
16677 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
16678 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
16679 * src/scan-gram.l: Revamp regular expressions so that " and '
16680 do not confuse xgettext.
16681
16682 * src/struniq.h (struniq_new): Do not declare the return type
16683 to be 'const'; this violates the C standard.
16684 * src/struniq.c (struniq_new): Likewise.
16685
16686 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
16687
16688 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
16689 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
16690 linker.
16691
16692 2002-11-12 Akim Demaille <akim@epita.fr>
16693
16694 * Makefile.maint: Sync with Autoconf:
16695 (local_updates): New.
16696
16697 2002-11-12 Akim Demaille <akim@epita.fr>
16698
16699 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
16700
16701 2002-11-12 Akim Demaille <akim@epita.fr>
16702
16703 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
16704 locations.
16705
16706 2002-11-12 Akim Demaille <akim@epita.fr>
16707
16708 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
16709 not yyvalue.
16710
16711 2002-11-12 Akim Demaille <akim@epita.fr>
16712
16713 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
16714 Use it to test the GLR parser.
16715
16716 2002-11-12 Akim Demaille <akim@epita.fr>
16717
16718 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
16719 defines it.
16720 * data/glr.c (yystos): New.
16721 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
16722 (YYDSYMPRINT): New.
16723 (yyval): Don't define it, it is handled via M4.
16724 (yyrecoverParseError): Free verbosely the discarded symbols.
16725 * data/yacc.c (yysymprint): Remove, rather...
16726 (b4_yysymprint_generate): invoke.
16727 * data/c.m4 (b4_yysymprint_generate): New.
16728 Accept pointers as arguments, as opposed to the version from
16729 yacc.c.
16730 (b4_yydestruct_generate): Likewise.
16731 * tests/cations.at (Printers and Destructors): Use Bison directives
16732 instead of CPP macros.
16733 Don't rely on internal details.
16734
16735 2002-11-12 Akim Demaille <akim@epita.fr>
16736
16737 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
16738 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
16739 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
16740 it against YYEMPTY and so forth), work on yytoken (i.e., set
16741 it to YYEMPTY etc.).
16742 (yydestruct): Replace with a b4_yydestruct_generate invocation.
16743 (b4_symbol_actions): Remove.
16744 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
16745 for 0, end-of-input.
16746
16747 2002-11-12 Akim Demaille <akim@epita.fr>
16748
16749 * doc/bison.texinfo (Destructor Decl): New.
16750
16751 2002-11-12 Akim Demaille <akim@epita.fr>
16752
16753 * src/tables.c (tables_generate): Use free for pointers that
16754 cannot be NULL, not XFREE.
16755 (pack_vector): Use assert, not fatal, for bound violations.
16756 * src/state.c (state_new): Likewise.
16757 * src/reader.c (reader): Likewise.
16758 * src/lalr.c (set_goto_map): Likewise.
16759 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
16760 the file name.
16761
16762 2002-11-12 Akim Demaille <akim@epita.fr>
16763
16764 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
16765 Restore.
16766 * src/scan-gram.l (last_string): Is global to the file, not to
16767 yylex.
16768 * src/parse-gram.y (input): Don't append the epilogue here,
16769 (epilogue.opt): do it here, and free the scanner's obstack.
16770 * src/reader.c (epilogue_set): Rename as...
16771 (epilogue_augment): this.
16772 * data/c.m4 (b4_epilogue): Defaults to empty.
16773
16774 2002-11-12 Akim Demaille <akim@epita.fr>
16775
16776 * src/getargs.c (long_options): Remove duplicates.
16777 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
16778 Remove.
16779 * doc/bison.rnh: Remove.
16780 * doc/bison.texinfo (VMS Invocation): Remove.
16781
16782 2002-11-12 Akim Demaille <akim@epita.fr>
16783
16784 * src/struniq.h, src/struniq.c (struniq_t): Is const.
16785 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
16786
16787 Use struniq for symbols.
16788
16789 * src/symtab.h (symbol_t): The tag member is a struniq.
16790 (symbol_type_set): Adjust.
16791 * src/symtab.c (symbol_new): Takes a struniq.
16792 (symbol_free): Don't free the tag member.
16793 (hash_compare_symbol_t, hash_symbol_t): Rename as...
16794 (hash_compare_symbol, hash_symbol): these.
16795 Use the fact that tags as struniqs.
16796 (symbol_get): Use struniq_new.
16797 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
16798 Returns a strniq.
16799 * src/reader.h (merger_list, grammar_currentmerge_set): The name
16800 and type members are struniqs.
16801 * src/reader.c (get_merge_function)
16802 (grammar_current_rule_merge_set): Adjust.
16803 (TYPE, current_type): Are struniq.
16804
16805 Use struniq for file names.
16806
16807 * src/files.h, src/files.c (infile): Split into...
16808 (grammar_file, current_file): these.
16809 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
16810 * src/reduce.c (reduce_print): Likewise.
16811 * src/getargs.c (getargs): Likewise.
16812 * src/complain.h, src/complain.c: Likewise.
16813 * src/main.c (main): Call struniqs_new early enough to use it for
16814 file names.
16815 Don't free the input file name.
16816
16817 2002-11-12 Akim Demaille <akim@epita.fr>
16818
16819 * src/symtab.c (symbol_free): Remove dead deactivated code:
16820 type_name are properly removed.
16821 Don't use XFREE to free items that cannot be NULL.
16822 * src/struniq.h, src/struniq.c: New.
16823 * src/main.c (main): Initialize/free struniqs.
16824 * src/parse-gram.y (%union): Add astruniq member.
16825 (yyprint): Adjust.
16826 * src/scan-gram.l (<{tag}>): Return a struniq.
16827 Free the obstack bit that used to store it.

16829
16830 2002-11-11 Paul Eggert <eggert@twinsun.com>
16831
16832 Revamp to fix many (but not all) of the C- and M4-related quoting
16833 problems. Among other things, this fixes the Bison bug reported
16834 by Jan Hubicka when processing the Bash grammar; see:
16835 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
16836
16837 Use new @ escapes consistently. Represent brackets with @{ and @}
16838 rather than @<:@ and @:>@, since this works a bit better with dumb
16839 editors like vi. Represent @ with @@, since @ is now consistently
16840 an escape. Use @oline@ and @ofile@ rather than __oline__ and
16841 __ofile__, to avoid unexpected expansions. Similarly, use @output
16842 rather than #output.
16843
16844 * data/c.m4 (b4_copyright): Omit file name from comment, since
16845 the file name could contain "*/".
16846 (b4_synclines_flag): Don't quote the 2nd argument; it should already
16847 be quoted. All uses changed.
16848
16849 * data/glr.c: Use new @ escapes consistently.
16850 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
16851 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
16852 Remove, since they couldn't handle arbitrary characters in file
16853 names.
16854 * data/lalr1.cc: Likewise.
16855 * data/yacc.c: Likewise.
16856
16857 * src/files.c (output_infix): Remove; all uses removed.
16858 * src/files.h: Likewise.
16859
16860 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
16861 mishandled funny characters in file names, and anyway it isn't
16862 needed any more.
16863 * data/yacc.c: Likewise.
16864 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
16865
16866 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
16867 * data/yacc.c: Likewise.
16868
16869 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
16870 strings now.
16871 (muscle_init): Quote filename as a C string.
16872 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
16873 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
16874 * src/output.c (escaped_file_name_output): New function.
16875 (prepare_symbols): Quote tokens for M4.
16876 (prepare): Don't insert output_infix, output_prefix,
16877 output_parser_name, output_header_name; this is now down by scan-skel.
16878 Insert skeleton as a C string.
16879
16880 * src/output.c (user_actions_output, symbol_destructors_output,
16881 symbol_printers_output): Quote filenames for C and M4.
16882 * src/reader.c (prologue_augment, epilogue_set): Likewise.
16883
16884 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
16885 escapes other than \\ and \'; this simplifies the code.
16886 (<SC_STRING>): Likewise, for \\ and \".
16887 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
16888 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
16889 Use new escapes @{ and @} for [ and ].
16890
16891 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
16892 them with auto vars.
16893 Switch to new escape scheme, where @ is the escape character uniformly.
16894 Abort if a stray escape character is found. Avoid unbounded input
16895 buffer when parsing non-escaped text.
16896
16897 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
16898 __oline__, #output, $@, and @{ do not have unintended meanings.
16899
16900 2002-11-09 Paul Eggert <eggert@twinsun.com>
16901
16902 Fix the test failure due to GCC warnings described in
16903 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
16904 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
16905 evaluate to 0 if it's impossible for NINF to be in the respective
16906 table.
16907 (yygetLRActions, yyrecoverParseError): Use them.
16908
16909 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
16910 counted in the token inserted at end of file. Now takes
16911 location_t *, not location_t, so that the location can be
16912 adjusted. All uses changed.
16913
16914 * tests/regression.at (Invalid inputs): Adjust wording in
16915 diagnostic to match the new behavior.
16916
16917 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
16918 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
16919 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
16920 abort ();'. This reduces the runtime of the "Many lookaheads"
16921 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
16922 GCC 3.2.
16923
16924 2002-11-07 Paul Eggert <eggert@twinsun.com>
16925
16926 * src/parse-gram.y (CHARACTER): Remove unused token.
16927 All uses removed.
16928
16929 * src/scan-gram.l: Remove stack option. We no longer use the
16930 stack, since the stack was never deeper than 1; instead, use the
16931 new auto var c_context to record the stacked value.
16932
16933 Remove nounput option. At an unexpected end of file, we now unput
16934 the minimal input necessary to end cleanly; this simplifies the
16935 code.
16936
16937 Avoid unbounded token sizes where this is easy.
16938
16939 (unexpected_end_of_file): New function.
16940 Use it to systematize the error message on unexpected EOF.
16941 (last-string): Now auto, not static.
16942 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
16943 (scanner_last_string_free): Remove; not used.
16944 (percent_percent_count): Move decl to just before use.
16945 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
16946 not the (never otherwised-used) CHARACTER.
16947
16948 2002-11-07 Akim Demaille <akim@epita.fr>
16949
16950 Let yyerror always receive the msg as last argument, so that
16951 yyerror can be variadic.
16952
16953 * data/yacc.c (b4_yyerror_args): New.
16954 Use it when calling yyerror.
16955 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
16956 Use it when calling yyerror.
16957 * doc/bison.texinfo (Error Reporting): Adjust.
16958 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
16959 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
16960

16997
16998 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16999
17000 * src/tables.c (matching_state): Don't allow states to match if
17001 either has GLR conflict entries.
17002
17003 2002-11-05 Paul Eggert <eggert@twinsun.com>
17004
17005 * src/scan-gram.l: Use more accurate diagnostics, e.g.
17006 "integer out of range" rather than "invalid value".
17007 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
17008 accordingly.
17009
17010 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
17011 Also, remove one static variable in the scanner.
17012
17013 * src/scan-gram.l (braces_level): Now auto, not static.
17014 Initialize to zero if the compiler is being picky.
17015 (INITIAL): Clear braces_level instead of incrementing it.
17016 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
17017 as POSIX 1003.1-2001 requires.
17018 * src/system.h (IF_LINT): New macro, taken from coreutils.
17019 * configure.ac: Define "lint" if --enable-gcc-warnings.
17020
17021 2002-11-05 Akim Demaille <akim@epita.fr>
17022
17023 * src/scan-gram.l: When it starts with `%', complain about the
17024 whole directive, not just that `invalid character: %'.
17025
17026 2002-11-04 Akim Demaille <akim@epita.fr>
17027
17028 * Makefile.maint: Update from Autoconf.

17030
17031 2002-11-04 Akim Demaille <akim@epita.fr>
17032
17033 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
17034 and yyerror.
17035 Have yyerror `use' its arguments.
17036 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
17037 returns true when location & yacc & pure & parse-param.
17038 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
17039
17040 2002-11-04 Akim Demaille <akim@epita.fr>
17041
17042 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
17043 clashes.
17044 * src/scan-gram.l: Use [\'] instead of ['] to pacify
17045 font-lock-mode.
17046 Use complain_at.
17047 Use quote, not quote_n since LOCATION_PRINT no longer uses the
17048 slot 0.
17049
17050 2002-11-03 Paul Eggert <eggert@twinsun.com>
17051
17052 * src/reader.c (get_merge_function, grammar_current_rule_check):
17053 Use consistent diagnostics for reporting type name clashes.
17054 Quote the types with <>, for consistency with Yacc.
17055 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
17056
17057 2002-11-03 Akim Demaille <akim@epita.fr>
17058
17059 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):

17069 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
17070 b4_user_formals and b4_user_args.
17071 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
17072 (yyreportAmbiguity): When using a pure parser, also need
17073 the location, and the parse-params.
17074 Adjust callers.
17075 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
17076 When using a pure parser, also need the parse-params.
17077 Adjust callers.
17078 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
17079 (%pure-parser + %parse-param) LALR and GLR parsers.
17080 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
17081 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

17088 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
17089 (Error Reporting): Adjust to these new directives.
17090 Document %error-verbose, deprecate YYERROR_VERBOSE.
17091
17092 2002-11-03 Akim Demaille <akim@epita.fr>
17093
17094 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
17095 AT_CHECK_CALC_GLR invocations to use % directives, instead of
17096 command line options.
17097 * tests/cxx-type.at: Formatting changes.
17098
17099 2002-11-03 Paul Eggert <eggert@twinsun.com>
17100
17101 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
17102 to count columns correctly, and to check for invalid inputs.
17103
17104 Use mbsnwidth to count columns correctly. Account for tabs, too.
17105 Include mbswidth.h.
17106 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
17107 (extend_location): New function.
17108 (YY_LINES): Remove.
17109
17110 Handle CRLF in C code rather than in Lex code.
17111 (YY_INPUT): New macro.
17112 (no_cr_read): New function.
17113
17114 Scan UCNs, even though we don't fully handle them yet.
17115 (convert_ucn_to_byte): New function.
17116
17117 Handle backslash-newline correctly in C code.
17118 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
17119 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
17120 all uses changed.
17121 (tag, splice): New EREs. Do not allow NUL or newline in tags.
17122 Use {splice} wherever C allows backslash-newline.
17123 YY_STEP after space, newline, vertical-tab.
17124 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
17125
17126 (letter, id): Don't assume ASCII; e.g., spell out a-z.
17127
17128 ({int}, handle_action_dollar, handle_action_at): Check for integer
17129 overflow.
17130
17131 (YY_STEP): Omit trailing semicolon, so that it's more like C.
17132
17133 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
17134 as well as \000. Check for UCHAR_MAX, not 255.
17135 Allow \x with an arbitrary positive number of digits, as in C.
17136 Check for overflow here.
17137 Allow \? and UCNs, for compatibility with C.
17138
17139 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
17140 with quote slot used by complain_at.
17141
17142 * tests/input.at: Add tests for backslash-newline, m4 quotes
17143 in symbols, long literals, and funny escapes in strings.
17144
17145 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
17146 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
17147 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
17148 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
17149 * m4/mbswidth.m4: New file, from GNU coreutils.
17150
17151 * doc/bison.texinfo (Grammar Outline): Document // comments.
17152 (Symbols): Document that trigraphs have no special meaning in Bison,
17153 nor is backslash-newline allowed.
17154 (Actions): Document that trigraphs have no special meaning.
17155
17156 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
17157 no longer used.
17158
17159 2002-11-02 Paul Eggert <eggert@twinsun.com>
17160
17161 * src/reader.c: Don't include quote.h; not needed.
17162 (get_merge_function): Reword warning to be consistent with
17163 type clash diagnostic in grammar_current_rule_check.
17164
17165 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
17166 bug in trigraph handling.
17167
17168 * src/output.c (prepare_symbols): When printing token names,
17169 escape "[" as "@<:@" and likewise for "]".
17170
17171 * src/system.h (errno): Remove declaration, as we are now
17172 assuming C89 or better, and C89 guarantees errno.
17173
17174 2002-10-30 Paul Eggert <eggert@twinsun.com>
17175
17176 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
17177 Check for close failures.
17178 * src/files.h (xfclose): Return void, not int, since it always
17179 returned zero.
17180 * src/files.c (xfclose): Likewise. Report I/O error if ferror
17181 indicates one.
17182 * src/output.c (output_skeleton): Use xfclose rather than fclose
17183 and ferror. xfclose now checks ferror.
17184
17185 * data/glr.c (YYLEFTMOST_STATE): Remove.
17186 (yyreportTree): Use a stack-based leftmost state. This avoids
17187 our continuing battles with bogus warnings about initializers.
17188
17189 2002-10-30 Akim Demaille <akim@epita.fr>
17190
17191 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
17192 #if.
17193
17194 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
17195
17196 * tests/glr-regr1.at: New test for reported regressions.
17197 * tests/testsuite.at: Add glr-regr1.at test.
17198 * tests/Makefile.am: Add glr-regr1.at test.
17199
17200 2002-10-24 Paul Eggert <eggert@twinsun.com>
17201
17202 Version 1.75a.
17203
17204 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
17205 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
17206 we use malloc. Don't assume 'A' through 'Z' are contiguous.
17207 Don't assume strdup exists; POSIX says its an XSI extension.
17208 Check for buffer overflow on input.
17209
17210 2002-10-24 Akim Demaille <akim@epita.fr>
17211
17212 * src/output.c (output_skeleton): Don't disable M4sugar comments
17213 too soon: it results in comments being expanded.
17214 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
17215 first output.
17216
17217 2002-10-24 Akim Demaille <akim@epita.fr>
17218
17219 * data/yacc.c (m4_int_type): New.
17220 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
17221 char' as only yacc.c wants K&R portability.
17222 * data/glr.c (yysigned_char): Remove.
17223 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
17224 Reported by Quoc Peyrot.
17225
17226 2002-10-23 Paul Eggert <eggert@twinsun.com>
17227
17228 * src/main.c (main): With --trace=time, report times even if a
17229 non-fatal error occurs. Formerly, the times were reported in some
17230 such cases but not in others.
17231 * src/reader.c (reader): Just return if a complaint has been issued,
17232 instead of exiting, so that 'main' can report times.
17233
17234 2002-10-22 Akim Demaille <akim@epita.fr>
17235
17236 * src/system.h: Include sys/types.
17237 Reported by Bert Deknuydt.
17238
17239 2002-10-23 Paul Eggert <eggert@twinsun.com>
17240
17241 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
17242 Suggested by Art Haas.
17243
17244 2002-10-22 Paul Eggert <eggert@twinsun.com>
17245
17246 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
17247 decl; not needed any more.
17248 * src/main.c (main): Use return to exit, undoing yesterday's change.
17249 The last OS that we could find where this wouldn't work is
17250 SunOS 3.5, and that's too old to worry about now.
17251
17252 * data/glr.c (struct yyltype): Define members even when not
17253 doing locations. This is more consistent with yacc.c, and it
17254 works around the following bug reports:
17255 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
17256 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
17257
17258 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
17259 @acronym consistently. Standardize on "Yacc" instead of "YACC",
17260 "Algol" instead of "ALGOL". Give a bit more history about BNF.
17261
17262 2002-10-22 Akim Demaille <akim@epita.fr>
17263
17264 * data/README: New.
17265
17266 2002-10-21 Paul Eggert <eggert@twinsun.com>
17267
17268 Be consistent about 'bool'; the old code used an enum in one
17269 module and an int in another, and this violates the C standard.
17270 * m4/stdbool.m4: New file, from coreutils 4.5.3.
17271 * configure.ac (AC_HEADER_STDBOOL): Add.
17272 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
17273 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
17274 * src/symtab.c (hash_compare_symbol_t): Likewise.
17275 * src/system.h (bool, false, true): Use a definition consistent
17276 with ../lib/hash.c. All uses changed.
17277
17278 * src/complain.c (warning_issued): Renamed from warn_message_count,
17279 so that we needn't worry about integer overflow (!).
17280 Now of type bool. All uses changed.
17281 (complaint_issued): Renamed from complain_message_count; likewise.
17282
17283 * src/main.c (main): Use exit to exit with failure.
17284
17285 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
17286 rather than 1 and 0.
17287 * src/main.c (main): Likewise.
17288 * src/getargs.c (getargs): Likewise.
17289 * src/reader.c (reader): Likewise.
17290
17291 * src/getarg.c (getargs): Remove duplicate code for
17292 "Try `bison --help'".
17293
17294 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
17295 What was that "2" for?
17296
17297 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
17298 * src/getargs.c (usage): Likewise.
17299
17300 * src/getargs.c (getargs): When there are too few operands, report
17301 the last one. When there are too many, report the first extra
17302 one. This is how diffutils does it.
17303
17304 2002-10-20 Paul Eggert <eggert@twinsun.com>
17305
17306 Remove K&R vestiges.
17307 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
17308 * src/complain.c (VA_START): Remove. Assume prototypes.
17309 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
17310 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
17311 fatal): Assume prototypes.
17312 * src/complain.h: Assume prototypes.
17313 * src/system.h (PARAMS): Remove.
17314 Include <limits.h> unconditionally, since it's guaranteeed even
17315 for a freestanding C89 compiler.
17316 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
17317 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
17318
17319 2002-10-20 Akim Demaille <akim@epita.fr>
17320
17321 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
17322 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
17323 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
17324 (yyresolveStates, yyresolveAction, yyresolveStack)
17325 (yyprocessOneStack): Use them.
17326 (yy_reduce_print): New.
17327 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
17328
17329 2002-10-20 Akim Demaille <akim@epita.fr>
17330
17331 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
17332 arguments and output `void'.
17333 (b4_c_function): Rename as...
17334 (b4_c_function_def): this.
17335 (b4_c_function_decl, b4_c_ansi_function_def)
17336 (b4_c_ansi_function_decl): New.
17337 Change the interpretation of the arguments: before `int, foo', now
17338 `int foo, foo'.
17339 * data/yacc.c (yyparse): Prototype and define thanks to these.
17340 Adjust b4_c_function_def uses.
17341 * data/glr.c (yyparse): Likewise, but ANSI only.
17342
17343 2002-10-20 Akim Demaille <akim@epita.fr>
17344
17345 * src/output.c (prepare): Move the definition of `tokens_number',
17346 `nterms_number', `undef_token_number', `user_token_number_max'
17347 to...
17348 (prepare_tokens): Here.
17349 (prepare_tokens): Rename as...
17350 (prepare_symbols): this.
17351 (prepare): Move the definition of `rules_number' to...
17352 (prepare_rules): here.
17353 (prepare): Move the definition of `last', `final_state_number',
17354 `states_number' to...
17355 (prepare_states): here.
17356 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
17357
17358 2002-10-20 Akim Demaille <akim@epita.fr>
17359
17360 * src/tables.h, src/tables.c, src/output.c: Comment changes.
17361
17362 2002-10-20 Akim Demaille <akim@epita.fr>
17363
17364 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
17365 * data/c.m4: here.
17366
17367 2002-10-20 Akim Demaille <akim@epita.fr>
17368
17369 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
17370 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
17371 `pair'.
17372 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
17373 `name' to...
17374 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
17375 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
17376 These.
17377
17378 2002-10-19 Paul Eggert <eggert@twinsun.com>
17379
17380 Do not create a temporary file, as that involves security and
17381 cleanup headaches. Instead, use a pair of pipes.
17382 Derived from a suggestion by Florian Krohm.
17383 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
17384 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
17385 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
17386 (BISON_PREREQ_SUBPIPE): Add.
17387 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
17388 Add subpipe.h, subpipe.c.
17389 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
17390 * po/POTFILES.in: Add lib/subpipe.c.
17391 * src/output.c: Include "subpipe.h".
17392 (m4_invoke): Remove decl.
17393 (scan_skel): New decl.
17394 (output_skeleton): Use pipe rather than temporary file for m4 input.
17395 Check that m4sugar.m4 is readable, to avoid deadlock.
17396 Check for pipe I/O error.
17397 * src/scan-skel.l (readpipe): Remove decl.
17398 (scan_skel): New function, to be used in place of m4_invoke.
17399 Read from stream rather than file.
17400
17401 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
17402 float, as this generates a warning on Solaris 8 + GCC 3.2 with
17403 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
17404 this generates a more-accurate value anyway.
17405
17406 * lib/timevar.c (timervar_accumulate): Rename locals to
17407 avoid confusion with similarly-named more-global.
17408 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
17409
17410 * src/output.c (prepare): Use xstrdup to convert char const *
17411 to char *, to avoid GCC warning.
17412
17413 2002-10-19 Akim Demaille <akim@epita.fr>
17414
17415 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
17416 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
17417 Use them to have `calc.y' ready for %pure-parser.
17418 * data/yacc.c (YYLEX): Pass a yylex return type to
17419 b4_c_function_call.
17420
17421 2002-10-19 Akim Demaille <akim@epita.fr>
17422
17423 Prototype support of %lex-param and %parse-param.
17424
17425 * src/parse-gram.y: Add the definition of the %lex-param and
17426 %parse-param tokens, plus their rules.
17427 Drop the `_' version of %glr-parser.
17428 Add the "," token.
17429 * src/scan-gram.l (INITIAL): Scan them.
17430 * src/muscle_tab.c: Comment changes.
17431 (muscle_insert, muscle_find): Rename `pair' as `probe'.
17432 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
17433 (muscle_entry_s): The `value' member is no longer const.
17434 Adjust all dependencies.
17435 * src/muscle_tab.c (muscle_init): Adjust: use
17436 MUSCLE_INSERT_STRING.
17437 Initialize the obstack earlier.
17438 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
17439 (muscle_pair_list_grow): New.
17440 * data/c.m4 (b4_c_function_call, b4_c_args): New.
17441 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
17442 * tests/calc.at: Use %locations, not --locations.
17443 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
17444
17445 2002-10-19 Akim Demaille <akim@epita.fr>
17446
17447 * src/getargs.c (usage): Take status as argument and exit
17448 accordingly.
17449 Report the traditional `Try ... --help' message when status != 0.
17450 (usage, version): Don't take a FILE * as arg, it is pointless.
17451 (getargs): When there is an incorrect number of arguments, make it
17452 an error, and report it GNUlically thanks to `usage ()'.
17453
17454 2002-10-18 Paul Eggert <eggert@twinsun.com>
17455
17456 * data/glr.c (yyreportParseError): Don't assume that sprintf
17457 yields the length of the printed string, as this is not true
17458 on SunOS 4.1.4. Reported by Peter Klein.
17459
17460 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
17461 * tests/conflicts.at (%nonassoc and eof): Likewise.
17462 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
17463
17464 2002-10-17 Akim Demaille <akim@epita.fr>
17465
17466 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
17467 * src/getargs.c (trace_types, trace_args): Adjust.
17468 * src/reader.c (grammar_current_rule_prec_set)
17469 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
17470 Standardize error messages.
17471 And s/@prec/%prec/!
17472 (reader): Use trace_flag to enable scanner/parser debugging,
17473 instead of an adhoc scheme.
17474 * src/scan-gram.l: Remove trailing debugging code.
17475
17476 2002-10-16 Paul Eggert <eggert@twinsun.com>
17477
17478 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
17479 MUSCLE_TAB_H.
17480
17481 * NEWS: Officially drop support for building Bison with K&R C,
17482 since it didn't work anyway and it's not worth worrying about.
17483 * Makefile.maint (wget_files): Remove ansi2knr.c.
17484 (ansi2knr.c-url_prefix): Remove.
17485 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
17486 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
17487 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
17488
17489 2002-10-15 Paul Eggert <eggert@twinsun.com>
17490
17491 Stop using the "enum_" trick for K&R-style function definitions;
17492 it confused me, and I was the author! Instead, assume that people
17493 who want to use K&R C compilers (when using these modules in GCC,
17494 perhaps?) will run ansi2knr.
17495
17496 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
17497 All uses of "enum_" changed to "enum ".
17498 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
17499 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
17500
17501 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

17508 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
17509 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
17510 Use function prototypes; this removes the need for declaring
17511 static functions simply to provide their prototypes.
17512 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

17565 2002-10-14 Akim Demaille <akim@epita.fr>
17566
17567 Version 1.75.
17568
17569 2002-10-14 Akim Demaille <akim@epita.fr>
17570
17571 * tests/Makefile.am (maintainer-check-posix): New.
17572
17573 2002-10-14 Akim Demaille <akim@epita.fr>
17574
17575 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
17576 member.
17577
17578 2002-10-14 Akim Demaille <akim@epita.fr>
17579
17580 * src/tables.c (table_ninf_remap): base -> tab.
17581 Reported by Matt Rosing.
17582
17583 2002-10-14 Paul Eggert <eggert@twinsun.com>
17584
17585 * tests/action.at, tests/calc.at, tests/conflicts.at,
17586 tests/cxx-type.at, tests/headers.at, tests/input.at,
17587 tests/regression.at, tests/synclines.at, tests/torture.at:
17588 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
17589 so that the tests still work even if POSIXLY_CORRECT is set.
17590 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
17591
17592 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
17593 for portability to K&R hosts. Fix typo: signed char is guaranteed
17594 only to 127, not to 128.
17595 * data/glr.c (yysigned_char): New type.
17596 * data/yacc.c (yysigned_char): Likewise.
17597 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
17598
17599 2002-10-13 Paul Eggert <eggert@twinsun.com>
17600
17601 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
17602 true due to limited range of data type" warning from GCC.
17603
17604 * data/c.m4 (b4_token_defines): Protect against double-inclusion
17605 by wrapping enum yytokentype's definition inside #ifndef
17606 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
17607
17608 2002-10-13 Akim Demaille <akim@epita.fr>
17609
17610 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
17611 Un yy- yyrhs to avoid the name clash with the global YYRHS.
17612
17613 2002-10-13 Akim Demaille <akim@epita.fr>
17614
17615 * Makefile.maint: Update from Autoconf 2.54.
17616 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
17617
17618 2002-10-13 Akim Demaille <akim@epita.fr>
17619
17620 * src/print.c (print_state): Separate the list of solved conflicts
17621 from the other items.
17622 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
17623
17624 2002-10-13 Akim Demaille <akim@epita.fr>
17625
17626 Let nondeterministic skeletons be usable with deterministic
17627 tables.
17628
17629 With the patch, GAWK compiled by GCC without -O2 passes its test
17630 suite using a GLR parser driven by LALR tables. It fails with -O2
17631 because `struct stat' gives two different answers on my machine:
17632 88 (definition of an auto var) and later 96 (memset on this var).
17633 Hence the stack is badly corrumpted. The headers inclusion is to
17634 blame: if I move the awk.h inclusion before GLR's system header
17635 inclusion, the two struct stat have the same size.
17636
17637 * src/tables.c (pack_table): Always create conflict_table.
17638 (token_actions): Always create conflict_list.
17639 * data/glr.c (YYFLAG): Remove, unused.
17640
17641 2002-10-13 Akim Demaille <akim@epita.fr>
17642
17643 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
17644 (O0FLAGS): New.
17645 (VALGRIND, GXX): New.
17646 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
17647 * tests/bison.in: Run $PREBISON a pre-command.
17648 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
17649 (maintainer-check-g++): New.
17650 * Makefile.am (maintainer-check): New.
17651
17652 2002-10-13 Akim Demaille <akim@epita.fr>
17653
17654 * data/glr.c: Formatting changes.
17655 Tweak some trace messages to match yacc.c's.
17656
17657 2002-10-13 Akim Demaille <akim@epita.fr>
17658
17659 GLR parsers sometimes raise parse errors instead of performing the
17660 default reduction.
17661 Reported by Charles-Henry de Boysson.
17662
17663 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
17664 check the length of the traces when %glr.
17665 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
17666 GLR's traces.
17667 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
17668 Test GLR parsers.
17669 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
17670 (yyltype): Remove the yy prefix from the member names.
17671 (yytable): Complete its comment.
17672 (yygetLRActions): Map error action number from YYTABLE from
17673 YYTABLE_NINF to 0.
17674 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
17675 (which was a bug: it should have been YYTABEL_NINF, and yet it was
17676 not satisfying as we could compare an YYACTION computed from
17677 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
17678 only value for error actions.
17679 (yyreportParseError): In verbose parse error messages, don't issue
17680 `error' in the list of expected tokens.
17681 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
17682 next action to perform to match glr.c's decoding.
17683 (yytable): Complete its comment.
17684
17685 2002-10-13 Paul Eggert <eggert@twinsun.com>
17686
17687 Fix problem reported by Henrik Grubbstroem in
17688 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
17689 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
17690 because the Bison parser reads the second action before reducing
17691 the first one.
17692 * src/scan-gram.l (rule_length): New static var.
17693 Use it to keep track of the rule length in the scanner, since
17694 we can't expect the parser to be in lock-step sync with the scanner.
17695 (handle_action_dollar, handle_action_at): Use this var.
17696 * tests/actions.at (Exotic Dollars): Test for the problem.
17697
17698 2002-10-12 Paul Eggert <eggert@twinsun.com>
17699
17700 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
17701 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
17702 Include <sys/time.h> when checking for clock_t and struct tms.
17703 Use same include order as source.
17704 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
17705 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
17706
17707 * lib/timevar.c: Update copyright date and clarify comments.
17708 (get_time) [IN_GCC]: Keep the GCC version for reference.
17709
17710 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
17711 GCC version as of today, then merge Bison's changes.
17712 Change "GCC" to "Bison" in copyright notice. timevar.def's
17713 author is Akim, so change that too.
17714
17715 * src/reader.c (grammar_current_rule_check):
17716 Don't worry about the default action if $$ is untyped.
17717 Prevents bogus warnings reported by Jim Gifford in
17718 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
17719
17720 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
17721 * data/glr.c, data/lalr1.cc, data/yacc.c:
17722 Output token definitions before the first part of user declarations.
17723 Fixes compatibility problem reported by Jim Gifford for kbd in
17724 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
17725
17726 2002-10-11 Paul Eggert <eggert@twinsun.com>
17727
17728 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
17729 (yyparse): here. This undoes some of the 2002-07-25 change.

17745
17746 Portability fixes for bitsets; this also avoids several GCC
17747 warnings.
17748
17749 * lib/abitset.c: Include <stddef.h>, for offsetof.
17750 * lib/lbitset.c: Likewise.
17751
17752 * lib/abitset.c (abitset_bytes): Return a size that is aligned
17753 properly for vectors of objects. Do not assume that adding a
17754 header size to a multiple of a word size yields a value that is
17755 properly aligned for the whole union.
17756 * lib/bitsetv.c (bitsetv_alloc): Likewise.
17757
17758 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
17759 unique names for structures.
17760 * lib/ebitset.c (ebitset_bytes): Likewise.
17761 * lib/lbitset.c (lbitset_bytes): Likewise.
17762
17763 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
17764 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
17765 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
17766 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
17767 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
17768 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
17769 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
17770 to improve the type-checking that GCC can do.
17771 * lib/bitset.c (bitset_op4_cmp): Likewise.
17772 * lib/bitset_stats.c (bitset_stats_count,
17773 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
17774 bitset_stats_copy, bitset_stats_disjoint_p,
17775 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
17776 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
17777 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
17778 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
17779 bitset_stats_and_or_cmp, bitset_stats_andn_or,
17780 bitset_stats_andn_or_cmp, bitset_stats_or_and,
17781 bitset_stats_or_and_cmp): Likewise.
17782 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
17783 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
17784 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
17785 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
17786
17787 * lib/abitset.h: Include bitset.h, not bbitset.h.
17788 * lib/ebitset.h: Likewise.
17789 * lib/lbitset.h: Likewise.
17790
17791 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
17792 All instances of parameters of type enum bitset_opts are now of
17793 type enum_bitset_opts, to conform to the C Standard, and similarly
17794 for enum_bitset_type.
17795 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
17796 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
17797
17798 Do not use "struct bitset_struct" to mean different things in
17799 different modules. Not only is this confusing, it violates
17800 the C Standard, which requires that structure types in different
17801 modules must be compatible if one is to be passed to the other.
17802 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
17803 All instances of "struct bitset_struct *" replaced with "bitset".
17804 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
17805 (union bitset_union, struct abitset_struct, struct ebitset_struct,
17806 struct lbitset_struct, struct bitset_stats_struct): New types.
17807 All uses of struct bitset_struct changed to union bitset_union,
17808 etc.
17809 * lib/abitset.c (struct abitset_struct, abitset,
17810 struct bitset_struct): Remove.
17811 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
17812 struct bitset_struct): Remove.
17813 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
17814 bitset_struct): Remove.
17815 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
17816 Likewise.
17817
17818 Do not call a function of type T using a call that assumes the
17819 function is of a different type U. Standard C requires that a
17820 function must be called with a type that is compatible with its
17821 definition.
17822 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17823 New decls.
17824 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17825 New functions.
17826 * lib/ebitset.c (PFV): Remove.
17827 * lib/lbitset.c (PFV): Likewise.
17828 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
17829 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
17830 decls.
17831 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
17832 (ebitset_vtable): Use them.
17833 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
17834 lbitset_xor): New functions.
17835 (lbitset_vtable): Use them.
17836
17837 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
17838 Declare.
17839
17840 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
17841 GCC warning.
17842 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
17843 Use offsetof, for simplicity.
17844
17845 2002-10-06 Paul Eggert <eggert@twinsun.com>
17846
17847 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
17848 the same width as int. This reapplies a hunk of the 2002-08-12 patch
17849 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
17850 which was inadvertently undone by the 2002-09-30 patch.
17851 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
17852 the same width as int.
17853
17854 2002-10-04 Paul Eggert <eggert@twinsun.com>
17855

17859
17860 * doc/bison.texinfo: Minor spelling, grammar, and white space
17861 fixes.
17862 (Symbols): Mention that any negative value returned from yylex
17863 signifies end-of-input. Warn about negative chars. Mention
17864 the portable Standard C character set.
17865
17866 The GNU coding standard says CFLAGS and YFLAGS are reserved
17867 for the installer to set.
17868 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
17869 * src/Makefile.am (AM_CFLAGS): Likewise.
17870 (AM_YFLAGS): Renamed from YFLAGS.
17871
17872 Fix some MAX and MIN problems.

17876 * src/reader.c (reader): Use it.
17877

17912 Likewise.
17913
17914 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
17915 Use size_t, not unsigned int, to count bytes.

17932 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
17933 abitset_or_and, abitset_or_and_cmp):
17934 Use bitset_windex instead of unsigned int.
17935 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.

17951 BITSET_SIZE_MAX): New macros.
17952 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
17953 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
17954 to BITSET_WINDEX_MAX.
17955
17956 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
17957 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

18057
18058 * doc/bison.texinfo (Conditions): Make explicit that the GPL

18077 2002-09-04 Akim Demaille <akim@epita.fr>
18078
18079 * configure.in: Rename as...

18106 * data/glr.c: Include string.h, for strlen.
18107 (yyreportParseError): Use size_t for yysize.
18108 (yy_yypstack): No longer nested inside yypstates, as nested
18109 functions are not portable. Do not assume size_t is the
18110 same width as int.
18111 (yypstates): Do not assume that ptrdiff_t is the same width
18112 as int, and similarly for yyposn and YYINDEX.
18113
18114 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

18152
18153 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
18154 PROTOTYPES to check for prototypes, and "defined __STDC__" to
18155 check for void *.
18156
18157 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
18158 size_t; the old version tried to do this but casted improperly.
18159 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
18160 (bitset_test): Now returns int, not unsigned long.
18161

18163 (_): New macro.
18164 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
18165 name locals "index", as it generates unnecessary warnings on some
18166 hosts that have an "index" function.

18190 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
18191 lib/timevar.c.
18192 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
18193 manual recommends.
18194 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
18195
18196 * src/complain.c (strerror_r): Remove decl; not needed.
18197 (strerror): Use same pattern as ../lib/error.c.
18198
18199 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
18200
18201 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
18202

18204 to void, to avoid a GCC warning when --disable-nls is in effect.
18205
18206 * src/scan-gram.l: Use strings rather than escapes when possible,
18207 to minimize the number of warnings from xgettext.
18208 (handle_action_dollar, handle_action_at): Don't use isdigit,
18209 as it mishandles negative chars and it may not work as expected
18210 outside the C locale.
18211
18212 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
18213 this is a GCC extension and is not portable to other compilers.
18214
18215 * src/system.h (alloca): Use same pattern as ../lib/error.c.
18216 Do not include <ctype.h>; no longer needed.
18217 Do not include <malloc.h>; no longer needed (and generates
18218 warnings on OpenBSD 3.0).
18219
18220 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
18221 it's not portable.
18222
18223 * tests/regression.at: Do not use 'cc -c input.c -o input';
18224 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
18225
18226 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
18227 exit status as failure, not just exit status 1. Sun C exits
18228 with status 2 sometimes.
18229
18230 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
18231 Use it for the two large tests.

18243 * src/tables.c (action_row): Move the computation of rules never
18244 reduced to...
18245 (token_actions): here.
18246 * src/main.c (main): Make the parser before making the report, so
18247 that rules never reduced are computed.
18248 Call grammar_rules_never_reduced_report.
18249 * src/print.c (print_results): Report rules never reduced.
18250 * tests/conflicts.at, tests/reduce.at: Adjust.
18251
18252 2002-08-01 Akim Demaille <akim@epita.fr>
18253
18254 Instead of attaching lookaheads and duplicating the rules being
18255 reduced by a state, attach the lookaheads to the reductions.
18256
18257 * src/state.h (state_t): Remove the `lookaheads',
18258 `lookaheads_rule' member.
18259 (reductions_t): Add a `lookaheads' member.
18260 Use a regular array for the `rules'.

18271 (initialize_LA): this.
18272 (lalr_free): Adjust.
18273 * src/main.c (main): Don't free nullable and derives too early: it
18274 is used by --verbose.
18275 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
18276
18277 2002-08-01 Akim Demaille <akim@epita.fr>

18286 (rule_list_t): Store rule_t *, not rule_number_t.
18287 * src/state.c (state_rule_lookaheads_print): Directly compare rule
18288 pointers, instead of their numbers.
18289 * src/main.c (main): Call nullable_free, and derives_free earlier,
18290 as they were lo longer used.
18291
18292 2002-08-01 Akim Demaille <akim@epita.fr>
18293
18294 * lib/timevar.c (get_time): Include children time.
18295 * src/lalr.h (LA, LArule): Don't export them: used with the
18296 state_t.
18297 * src/lalr.c (LA, LArule): Static.
18298 * src/lalr.h, src/lalr.c (lalr_free): New.
18299 * src/main.c (main): Call it.
18300 * src/tables.c (pack_vector): Check whether loc is >= to the
18301 table_size, not >.
18302 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
18303 (tables_generate): do it, since that's also it which allocates
18304 them.
18305 Don't free LA and LArule, main does.
18306
18307 2002-07-31 Akim Demaille <akim@epita.fr>

18343 * src/getargs.h, src/getargs.c: Support trace_time for
18344 --trace=time.
18345 * src/main.c (stage): Remove.
18346 (main): Replace `stage' invocations with timevar calls.
18347 * src/output.c: Insert pertinent timevar calls.
18348
18349 2002-07-31 Akim Demaille <akim@epita.fr>
18350
18351 Let --trace have arguments.
18352
18353 * src/getargs.h (enum trace_e): New.
18354 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
18355 (long_options, short_options): --trace/-T takes an optional
18356 argument.
18357 Change all the uses of trace_flag to reflect the new flags.
18358 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
18359
18360 Strengthen `stage' portability.
18361
18362 * m4/stage.m4 (BISON_PREREQ_STAGE): New.

18364 Don't check for malloc.h and sys/times.h.
18365 * src/system.h: Include them when appropriate.

18367 times and struct tms are available.
18368
18369 2002-07-30 Akim Demaille <akim@epita.fr>
18370
18371 In verbose parse error message, don't report `error' as an
18372 expected token.
18373 * tests/actions.at (Printers and Destructors): Adjust.
18374 * tests/calc.at (Calculator $1): Adjust.
18375 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
18376 error message, do not report the parser accepts the error token in
18377 that state.
18378
18379 2002-07-30 Akim Demaille <akim@epita.fr>
18380

18391 Report rules which are never reduced by the parser: those hidden
18392 by conflicts.
18393
18394 * src/LR0.c (save_reductions): Don't make the final state too
18395 different: save its reduction (accept) instead of having a state
18396 without any action (no shift or goto, no reduce).
18397 Note: the final state is now a ``regular'' state, i.e., the
18398 parsers now contain `reduce 0' as default reduction.
18399 Nevertheless, since they decide to `accept' when yystate =
18400 final_state, they still will not reduce rule 0.
18401 * src/print.c (print_actions, print_reduction): Adjust.
18402 * src/output.c (action_row): Track reduced rules.
18403 (token_actions): Report rules never reduced.

18412 * src/main.c (stage): Adjust.
18413 Report only when trace_flag.
18414

18416
18417 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not

18423 * src/print.c, src/print_graph.c: Adjust.
18424
18425 2002-07-29 Akim Demaille <akim@epita.fr>
18426
18427 Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $.
18428
18429 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
18430 (endtoken, accept): these.
18431 * src/reader.c (reader): Set endtoken's default tag to "$end".
18432 Set undeftoken's tag to "$undefined" instead of "$undefined.".
18433 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
18434 Adjust.
18435
18436 2002-07-29 Akim Demaille <akim@epita.fr>
18437
18438 * src/reduce.c (reduce_grammar): When the language is empty,
18439 complain about the start symbol, not the axiom.
18440 Use its location.
18441 * tests/reduce.at (Empty Language): New.
18442
18443 2002-07-26 Akim Demaille <akim@epita.fr>
18444
18445 * src/reader.h, src/reader.c (gram_error): ... can't get
18446 yycontrol without making too strong assumptions on the parser
18447 itself.
18448 * src/output.c (prepare_tokens): Use the real 0th value of
18449 token_translations instead of `0'.
18450 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
18451 visible here.
18452 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
18453 for the time being: %locations ought to provide it to yyerror.
18454
18455 2002-07-25 Akim Demaille <akim@epita.fr>
18456
18457 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

18460
18461 2002-07-25 Akim Demaille <akim@epita.fr>

18466 * src/nullable.c, src/output.c, src/print.c, src/reader.c
18467 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
18468 Iterate from 0 to nrules.
18469 Use rule_number_as_item_number and item_number_as_rule_number.
18470 Adjust to `derive' now containing possibly 0.
18471 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
18472 Handle the `- 1' part in rule numbers from/to item numbers.

18485 (b4_c_knr_arg_decl): New.
18486 * data/yacc.c: Use it to define yysymprint, yydestruct, and
18487 yyreport_parse_error.
18488
18489 2002-07-25 Akim Demaille <akim@epita.fr>
18490

18493 (yydestruct, yysymprint): Move above yyparse.
18494 Be K&R compliant.

19617
19618 Remove `%thong' support as it is undocumented, unused, duplicates
19619 `%token's job, and creates useless e-mail traffic with people who

19621 duplicates `%token's job.

19767
19768 * data/bison.simple (yyparse): Correct error handling to conform to
19769 POSIX and yacc. Specifically, after syntax error is discovered,

19781 the latter can be removed.
19782 (yy_token_number_type): Remove, only one use.

19997 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
19998 Note: this patch partially drops `semantic-parser' support: it
19999 always does `rule_length - n', where semantic parsers ought to
20000 always use `-n'.
20001 * data/bison.simple, data/bison.c++ (b4_lhs_value)
20002 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

20105 2002-04-22 Akim Demaille <akim@epita.fr>
20106
20107 * src/reader.c (token_translations_init): 256 is now the default
20108 value for the error token, i.e., it will be assigned another

20153
20154 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
20155 full stderr, and strip it according to the bison options, instead
20156 of composing the error message from different bits.
20157 This makes it easier to check for several error messages.
20158 Adjust all the invocations.
20159 Add an invocation exercising the error token.
20160 Add an invocation demonstrating a stupid error message.
20161 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

20172 * src/symtab.h: here.
20173 (state_t.number): Is a token_number_t.
20174 * src/print.c, src/reader.c: Use undeftoken->number instead of
20175 hard coded 2.
20176 (Even though this 2 is not the same as above: the number of the
20177 undeftoken remains being 2, it is its user token number which
20178 might not be 2).
20179 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
20180 `user_token_number_max'.

20430 2002-04-07 Akim Demaille <akim@epita.fr>
20431
20432 * data/bison.c++, data/bison.simple: Don't output the current file

20724 2002-02-14 Paul Eggert <eggert@twinsun.com>
20725
20726 Remove the support for C++ namespace cleanliness; it was
20727 causing more problems than it was curing, since it didn't work
20728 properly on some nonstandard C++ compilers. This can wait
20729 for a proper C++ parser.
20730
20731 * NEWS: Document this.

20774 more consistent when naming methods and variables. Put preprocessor
20775 directives around tables only needed for debugging.
20776
20777 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20778
20779 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

20819 (token_definitions_output): No longer keeps track of the output
20820 line number, hence remove the second argument.
20821 (guards_output): Check against the guard member of a rule, not the
20822 action member.
20823 Adjust callers.
20824 (output_skeleton): Don't look for the skeleton location, let m4 do
20825 that.
20826 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
20827 file will be used.
20828 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
20829 (prepare): Given that for the time being changesyntax is not
20830 usable in M4, rename the muscles using `-' to `_'.
20831 Define `defines_flag', `output_parser_name' and `output_header_name'.
20832 * src/output.h (actions_output, guards_output)
20833 (token_definitions_output): Adjust prototypes.
20834 * src/scan-skel.l: Instead of scanning the skeletons, it now
20835 processes the output of m4: `__oline__' and `#output'.

20837 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
20838 to date.

20861
20862 * src/bison.simple (YYSIZE_T): Do not define merely because
20863 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

20865
20866 2002-01-27 Akim Demaille <akim@epita.fr>
20867
20868 Fix `%nonassoc and eof'.
20869
20870 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
20871 which were not properly copied! Replace
20872 memcpy (res->errs, src->errs, src->nerrs);
20873 with
20874 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
20875 !!!
20876 * tests/regression.at (%nonassoc and eof): Adjust to newest
20877 Autotest: `.' is not in the PATH.

20935
20936 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>

20996

21032 2002-01-03 Akim Demaille <akim@epita.fr>
21033
21034 * src/parse-skel.y (process_skeleton): Don't bind the parser's
21035 tracing code to --trace, wait for a better --trace option, with
21036 args.
21037
21038 2002-01-03 Akim Demaille <akim@epita.fr>
21039
21040 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
21041 The ISO C++ standard is extremely clear about it: stderr is
21042 considered a macro, not a regular symbol (see table 94 `Header
21043 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
21044 Therefore std:: does not apply to it. It still does with fprintf.
21045 Also, s/cstdio.h/cstdio/.
21046
21047 2002-01-03 Akim Demaille <akim@epita.fr>
21048
21049 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
21050 for non system headers.
21051
21052 2002-01-02 Akim Demaille <akim@epita.fr>
21053
21054 Equip the skeleton chain with location tracking, runtime trace,
21055 pure parser and scanner.
21056
21057 * src/parse-skel.y: Request a pure parser, locations, and prefix
21058 renaming.
21059 (%union): Having several members with the same type does not help
21060 type mismatches, simplify.
21061 (YYPRINT, yyprint): New.
21062 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
21063 (skel_error): this.
21064 Handle locations.
21065 * src/scan-skel.l: Adjust to these changes.
21066 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
21067 (LOCATION_PRINT, skel_control_t): New.
21068
21069 2001-12-30 Akim Demaille <akim@epita.fr>
21070
21071 * src/parse-skel.y: Get rid of the shift/reduce conflict:
21072 replace `gb' with BLANKS.
21073 * src/scan-skel.l: Adjust.
21074
21075 2001-12-30 Akim Demaille <akim@epita.fr>
21076
21077 * src/system.h: We don't need nor want bcopy.
21078 Throw away MS-DOS crap: we don't need getpid.
21079 * configure.in: We don't need strndup. It was even causing
21080 problems: because Flex includes the headers *before* us,
21081 _GNU_SOURCE is not defined by config.h, and therefore strndup was
21082 not visible.
21083 * lib/xstrndup.c: New.
21084 * src/scan-skel.l: Use it.
21085 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
21086 * src/parse-skel.y: Use %directives instead of #defines.
21087
21088 2001-12-30 Akim Demaille <akim@epita.fr>
21089
21090 * src/skeleton.h: New.
21091 * src/output.c (output_parser, output_master_parser): Remove, dead
21092 code.
21093 * src/output.h (get_lines_number, actions_output, guards_output)
21094 (token_definitions_output): Prototype them.
21095 * src/parse-skel.y: Add the license notice.
21096 Include output.h and skeleton.h.
21097 (process_skeleton): Returns void, and takes a single parameter.
21098 * src/scan-skel.l: Add the license notice.
21099 Include skeleton.h.
21100 Don't use %option yylineno: it seems that then Flex imagines
21101 REJECT has been used, and therefore it won't reallocate its
21102 buffers (which makes no other sense to me than a bug). It results
21103 in warnings for `unused: yy_flex_realloc'.
21104
21105 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
21106
21107 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
21108 (MUSCLE_INSERT_PREFIX): ...to there.
21109 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
21110 (MUSCLE_INSERT_PREFIX): Move from here...
21111
21112 * src/bison.hairy: Add a section directive. Put braces around muscle
21113 names. This parser skeleton is still broken, but Bison should not
21114 choke on a bad muscle 'syntax'.
21115 * src/bison.simple: Add a section directive. Put braces around muscle
21116 names.
21117
21118 * src/files.h (strsuffix, stringappend): Add declarations.
21119 (tab_extension): Add declaration.
21120 (short_base_name): Add declaration.
21121
21122 * src/files.c (strsuffix, stringappend): No longer static. These
21123 functions are used in the skeleton parser.
21124 (tab_extension): New.
21125 (compute_base_names): Use the computations done in this function
21126 to guess if the generated parsers should have '.tab' in their
21127 names.
21128 (short_base_name): No longer static.
21129
21130 * src/output.c (output_skeleton): New.
21131 (output): Disable call to output_master_parser, and give a try to
21132 a new skeleton handling system.
21133 (guards_output, actions_output): No longer static.
21134 (token_definitions_output, get_lines_number): No longer static.
21135
21136 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
21137
21138 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
21139 parse-skel.y.
21140
21141 * src/parse-skel.y: New file.
21142 * src/scan-skel.l: New file.
21143
21144 2001-12-29 Akim Demaille <akim@epita.fr>
21145
21146 %name-prefix is broken.
21147
21148 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
21149 Adjust all dependencies.
21150 * tests/headers.at (export YYLTYPE): Strengthen this test: use
21151 %name-prefix.
21152
21153 Renaming yylval but not yylloc is not consistent. Now we do.
21154
21155 * src/bison.simple: Prefix yylloc if used.
21156 * doc/bison.texinfo (Decl Summary): Document that.
21157
21158 2001-12-29 Akim Demaille <akim@epita.fr>
21159
21160 * doc/bison.texinfo: Promote `%long-directive' over
21161 `%long_directive'.
21162 Remove all references to fixed-output-files, yacc is enough.
21163
21164 2001-12-29 Akim Demaille <akim@epita.fr>
21165
21166 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
21167 user prologue. These are defaults.
21168 * tests/actions.at (Mid-rule actions): Make sure the user can
21169 define YYDEBUG and YYERROR_VERBOSE.
21170
21171 2001-12-29 Akim Demaille <akim@epita.fr>
21172
21173 * src/output.c (header_output): Don't forget to export YYLTYPE and
21174 yylloc.
21175 * tests/headers.at (export YYLTYPE): New, make sure it does.
21176 * tests/regression.at (%union and --defines, Invalid CPP headers):
21177 Move to...
21178 * tests/headers.at: here.
21179
21180 2001-12-29 Akim Demaille <akim@epita.fr>
21181
21182 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
21183
21184 2001-12-29 Akim Demaille <akim@epita.fr>
21185
21186 * tests/actions.at (Mid-rule actions): Output on a single line
21187 instead of several.
21188
21189 2001-12-29 Akim Demaille <akim@epita.fr>
21190
21191 * doc/bison.texinfo: Formatting changes.
21192
21193 2001-12-29 Akim Demaille <akim@epita.fr>
21194
21195 Don't store the token defs in a muscle, just be ready to output it
21196 on command. Now possible via `symbols'. Fixes a memory leak.
21197
21198 * src/output.c (token_definitions_output): New.
21199 (output_parser, header_output): Use it.
21200 * src/reader.c (symbols_save): Remove.
21201
21202 2001-12-29 Akim Demaille <akim@epita.fr>
21203
21204 * src/bison.simple: Do not provide a default for YYSTYPE and
21205 YYLTYPE before the user's prologue. Otherwise it's hardly... a
21206 default.
21207
21208 2001-12-29 Akim Demaille <akim@epita.fr>
21209
21210 Mid-rule actions are simply... ignored!
21211
21212 * src/reader.c (readgram): Be sure to attach mid-rule actions to
21213 the empty-rule associated to the dummy symbol, not to the host
21214 rule.
21215 * tests/actions.at (Mid-rule actions): New.
21216
21217 2001-12-29 Akim Demaille <akim@epita.fr>
21218
21219 Memory leak.
21220
21221 * src/reader.c (reader): Free grammar.
21222
21223 2001-12-29 Akim Demaille <akim@epita.fr>
21224
21225 Memory leak.
21226
21227 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
21228 since it allocates it for each state, although only one is needed.
21229 (allocate_storage): Do it here.
21230
21231 2001-12-29 Akim Demaille <akim@epita.fr>
21232
21233 * src/options.h, src/options.c (create_long_option_table): Rename
21234 as...
21235 (long_option_table_new): this, with a clearer prototype.
21236 (percent_table): Remove, unused,
21237 * src/getargs.c (getargs): Adjust.
21238
21239 2001-12-29 Akim Demaille <akim@epita.fr>
21240
21241 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
21242 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
21243 as states.
21244
21245 2001-12-29 Akim Demaille <akim@epita.fr>
21246
21247 * src/lalr.c (build_relations): Rename `states' as `states1'.
21248 Sorry, I don't understand exactly what it is, no better name...
21249
21250 2001-12-29 Akim Demaille <akim@epita.fr>
21251
21252 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
21253 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
21254 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
21255 as rules.
21256
21257 2001-12-29 Akim Demaille <akim@epita.fr>
21258
21259 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
21260 ago.
21261
21262 2001-12-29 Akim Demaille <akim@epita.fr>
21263
21264 * src/reader.c, src/reader.h (user_toknums): Remove.
21265 Adjust all users to use symbols[i]->user_token_number.
21266
21267 2001-12-29 Akim Demaille <akim@epita.fr>
21268
21269 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
21270 Adjust all users to use symbols[i]->prec or ->assoc.
21271
21272 2001-12-29 Akim Demaille <akim@epita.fr>
21273
21274 * src/reader.c, src/reader.h (tags): Remove.
21275 Adjust all users to use symbols[i]->tag.
21276
21277 2001-12-29 Akim Demaille <akim@epita.fr>
21278
21279 * src/gram.h, src/gram.c (symbols): New, similar to state_table
21280 and rule_table.
21281 * src/reader.c (packsymbols): Fill this table.
21282 Drop sprec.
21283 * src/conflicts.c (resolve_sr_conflict): Adjust.
21284 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
21285 single table.
21286 Use symbols[i]->tag instead of tags[i].
21287
21288 2001-12-29 Akim Demaille <akim@epita.fr>
21289
21290 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
21291 In addition, put a comment in there, to replace...
21292 * tests/regression.at (%union and C comments): Remove.
21293
21294 2001-12-29 Akim Demaille <akim@epita.fr>
21295
21296 * tests/regression.at (Web2c Actions): Blindly move the actual
21297 output as expected output. The contents *seem* right to me, but I
21298 can't pretend reading perfectly parser tables... Nonetheless, all
21299 the other tests pass correctly, the table look OK, even though the
21300 presence of `$axiom' is to be noted: AFAICS it is useless (but
21301 harmless).
21302
21303 2001-12-29 Akim Demaille <akim@epita.fr>
21304
21305 * src/reader.c (readgram): Don't add the rule 0 if there were no
21306 rules read. In other words, add it _after_ having performed
21307 grammar sanity checks.
21308 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
21309
21310 2001-12-29 Akim Demaille <akim@epita.fr>
21311
21312 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
21313 visible, and some states have now a different number.
21314
21315 2001-12-29 Akim Demaille <akim@epita.fr>
21316
21317 * src/reader.c (readgram): Bind the initial rule's lineno to that
21318 of the first rule.
21319 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
21320 (Solved SR Conflicts): Adjust rule 0's line number.
21321
21322 2001-12-29 Akim Demaille <akim@epita.fr>
21323
21324 Fix the `GAWK Grammar' failure.
21325
21326 * src/LR0.c (final_state): Initialize to -1 so that we do compute
21327 the reductions of the first state which was mistakenly confused
21328 with the final state because precisely final_state was initialized
21329 to 0.
21330 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
21331 now noticed by Bison.
21332 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
21333 have a reduction on $default.
21334
21335 2001-12-29 Akim Demaille <akim@epita.fr>
21336
21337 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
21338 rule line numbers.
21339 * src/closure.c (print_closure): Likewise.
21340 * src/derives.c (print_derives): Likewise.
21341 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
21342 now.
21343
21344 2001-12-29 Akim Demaille <akim@epita.fr>
21345
21346 * src/lalr.c (lookaheads_print): New.
21347 (lalr): Call it when --trace-flag.
21348 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
21349 are dumped.
21350
21351 2001-12-29 Akim Demaille <akim@epita.fr>
21352
21353 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
21354 when walking through ritem, even via rule->rhs.
21355 * src/reduce.c (dump_grammar, useful_production, reduce_output)
21356 (useful_production, useless_nonterminals): Likewise.
21357 (reduce_grammar_tables): Likewise, plus update nritems.
21358 * src/nullable.c (set_nullable): Likewise.
21359 * src/lalr.c (build_relations): Likewise.
21360 * tests/sets.at (Nullable): Adjust.
21361 Fortunately, now, the $axiom is no longer nullable.
21362
21363 2001-12-29 Akim Demaille <akim@epita.fr>
21364
21365 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
21366 the 0-sentinel.
21367 * src/gram.c (ritem_longest_rhs): Likewise.
21368 * src/reduce.c (nonterminals_reduce): Likewise.
21369 * src/print_graph.c (print_graph): Likewise.
21370 * src/output.c (output_rule_data): Likewise.
21371 * src/nullable.c (set_nullable): Likewise.
21372
21373 2001-12-29 Akim Demaille <akim@epita.fr>
21374
21375 * src/output.c: Comment changes.
21376
21377 2001-12-27 Paul Eggert <eggert@twinsun.com>
21378
21379 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
21380 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
21381 Sparc, as they were causing more porting problems than the
21382 (minor) performance improvement was worth.
21383
21384 Also, catch up with 1.31's YYSTD.
21385
21386 2001-12-27 Akim Demaille <akim@epita.fr>
21387
21388 * src/output.c (output_gram): Rely on nritems, not the
21389 0-sentinel. See below.
21390 Use -1 as separator, not 0.
21391 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
21392 Rely on -1 as separator in yyrhs, instead of 0.
21393 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
21394 twice `Now at end of input', therefore there are two lines less to
21395 expect.
21396
21397 2001-12-27 Akim Demaille <akim@epita.fr>
21398
21399 * tests/regression.at (Unresolved SR Conflicts):
21400 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
21401 below.
21402
21403 2001-12-27 Akim Demaille <akim@epita.fr>
21404
21405 * src/LR0.c (new_state): Recognize the final state by the fact it
21406 is reached by eoftoken.
21407 (insert_start_shifting_state, insert_eof_shifting_state)
21408 (insert_accepting_state, augment_automaton): Remove, since now
21409 these states are automatically computed from the initial state.
21410 (generate_states): Adjust.
21411 * src/print.c: When reporting a rule number to the user, substract
21412 1, so that the axiom rule is rule 0, and the first user rule is 1.
21413 * src/reduce.c: Likewise.
21414 * src/print_graph.c (print_core): For the time being, just as for
21415 the report, depend upon --trace-flags to dump the full set of
21416 items.
21417 * src/reader.c (readgram): Once the grammar read, insert the rule
21418 0: `$axiom: START-SYMBOL $'.
21419 * tests/set.at: Adjust: rule 0 is now displayed, and since the
21420 number of the states has changed (the final state is no longer
21421 necessarily the last), catch up.
21422
21423 2001-12-27 Akim Demaille <akim@epita.fr>
21424
21425 Try to make the use of the eoftoken valid. Given that its value
21426 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
21427 is used instead of > 0 where appropriate, (ii), depend upon nritems
21428 instead of the 0-sentinel.
21429
21430 * src/gram.h, src/gram.c (nritems): New.
21431 Expected to be duplication of nitems, but for the time being...
21432 * src/reader.c (packgram): Assert nritems and nitems are equal.
21433 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
21434 * src/closure.c (print_closure, print_fderives): Likewise.
21435 * src/gram.c (ritem_print): Likewise.
21436 * src/print.c (print_core, print_grammar): Likewise.
21437 * src/print_graph.c: Likewise.
21438
21439 2001-12-27 Akim Demaille <akim@epita.fr>
21440
21441 * src/main.c (main): If there are complains after grammar
21442 reductions, then output the report anyway if requested, then die.
21443 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
21444 * src/reader.c (eoftoken): New.
21445 (parse_token_decl): If the token being defined has value `0', it
21446 is the eoftoken.
21447 (packsymbols): No longer hack `tags' to insert `$' by hand.
21448 Be sure to preserve the value of the eoftoken.
21449 (reader): Make sure eoftoken is defined.
21450 Initialize nsyms to 0: now eoftoken is created just like the others.
21451 * src/print.c (print_grammar): Don't special case the eof token.
21452 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
21453 lie anyway, albeit pleasant.
21454 * tests/calc.at: Exercise error messages with eoftoken.
21455 Change the grammar so that empty input is invalid.
21456 Adjust expectations.
21457 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
21458
21459 2001-12-27 Akim Demaille <akim@epita.fr>
21460
21461 * configure.in: Check the protos of strchr ans strspn.
21462 Replace strchr if needed.
21463 * src/system.h: Provide the protos of strchr, strspn and memchr if
21464 missing.
21465 * lib/strchr.c: New.
21466 * src/reader.c (symbols_save): Use strchr.
21467
21468 2001-12-27 Akim Demaille <akim@epita.fr>
21469
21470 * src/print.c, src/print_graph.c (escape): New.
21471 Use it to quote the TAGS outputs.
21472 * src/print_graph.c (print_state): Now errors are in red, and
21473 reductions in green.
21474 Prefer high to wide: output the state number on a line of its own.
21475
21476 2001-12-27 Akim Demaille <akim@epita.fr>
21477
21478 * src/state.h, src/state.c (reductions_new): New.
21479 * src/LR0.c (set_state_table): Let all the states have a
21480 `reductions', even if reduced to 0.
21481 (save_reductions): Adjust.
21482 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
21483 * src/print.c (print_reductions, print_actions): Adjust.
21484 * src/output.c (action_row): Adjust.
21485
21486 2001-12-27 Akim Demaille <akim@epita.fr>
21487
21488 * src/state.h, src/state.c (errs_new, errs_dup): New.
21489 * src/LR0.c (set_state_table): Let all the states have an errs,
21490 even if reduced to 0.
21491 * src/print.c (print_errs, print_reductions): Adjust.
21492 * src/output.c (output_actions, action_row): Adjust.
21493 * src/conflicts.c (resolve_sr_conflict): Adjust.
21494

21500
21501 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
21502 * src/print.c: here.
21503 (lookaheadset, shiftset): New, used as additional storage by
21504 print_reductions.
21505 (print_results): Adjust.
21506 (print_shifts, print_gotos, print_errs): New, extracted from...
21507 (print_actions): here.
21508 * src/print_graph.c (print_actions): Remove dead code.
21509
21510 2001-12-27 Akim Demaille <akim@epita.fr>
21511
21512 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
21513 `$n' and `@n'.
21514
21515 2001-12-27 Akim Demaille <akim@epita.fr>
21516
21517 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
21518 (build_relations): Adjust.
21519
21520 2001-12-27 Akim Demaille <akim@epita.fr>
21521
21522 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
21523 duplication.
21524
21525 2001-12-27 Akim Demaille <akim@epita.fr>
21526
21527 * src/reader.c (packgram): Catch nitems overflows.
21528
21529 2001-12-27 Akim Demaille <akim@epita.fr>
21530
21531 * src/files.c, src/files.h (guard_obstack): Remove.
21532 * src/output.c (output): Adjust.
21533 * src/reader.c (parse_braces): New, factoring...
21534 (copy_action, copy_guard): these two which are renamed as...
21535 (parse_action, parse_guard): these.
21536 As a voluntary consequence, using braces around guards is now
21537 mandatory.
21538
21539 2001-12-27 Akim Demaille <akim@epita.fr>
21540
21541 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
21542 * src/reader.c (symbol_list): `guard' and `guard_line' are new
21543 members.
21544 (symbol_list_new): Adjust.
21545 (copy_action): action_line is the first line, not the last.
21546 (copy_guard): Just as for actions, store the `action' only, not
21547 the switch/case/break flesh.
21548 Don't parse the user action that might follow the guard, let...
21549 (readgram): do it, i.e., now, there can be an action after a
21550 guard.
21551 In other words the guard is just explicitly optional.
21552 (packgram): Adjust.
21553 * src/output.c (guards_output): New.
21554 (output_parser): Call it when needed.
21555 (output): Also free the guard and attrs obstacks.
21556 * src/files.c, src/files.h (obstack_save): Remove.
21557 (output_files): Remove.
21558 As a result, if one needs the former `.act' file, using an
21559 appropriate skeleton which requires actions and guards is now
21560 required.
21561 * src/main.c (main): Adjust.
21562 * tests/semantic.at: New.
21563 * tests/regression.at: Use `input.y' as input file name.
21564 Avoid 8+3 problems by requiring input.c when the test needs the
21565 parser.
21566
21567 2001-12-27 Akim Demaille <akim@epita.fr>
21568
21569 * src/reader.c (symbol_list_new): Be sure to initialize all the
21570 fields.
21571
21572 2001-12-27 Akim Demaille <akim@epita.fr>
21573
21574 All the hacks using a final pseudo state are now useless.
21575
21576 * src/LR0.c (set_state_table): state_table holds exactly nstates.
21577 * src/lalr.c (nLA): New.
21578 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
21579 instead of lookaheadsp from the pseudo state (nstate + 1).
21580
21581 2001-12-27 Akim Demaille <akim@epita.fr>
21582
21583 * src/output.c (action_row, token_actions): Use a state_t instead
21584 of a integer, and nlookaheads instead of the following state's
21585 lookaheadsp.
21586
21587 2001-12-27 Akim Demaille <akim@epita.fr>
21588
21589 * src/conflicts.c (log_resolution, flush_shift)
21590 (resolve_sr_conflict, set_conflicts, solve_conflicts)
21591 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
21592 (conflicts_print, print_reductions): Use a state_t instead of an
21593 integer when referring to a state.
21594 As much as possible, depend upon nlookaheads, instead of the
21595 `lookaheadsp' member of the following state (since lookaheads of
21596 successive states are successive, the difference between state n + 1
21597 and n served as the number of lookaheads for state n).
21598 * src/lalr.c (add_lookback_edge): Likewise.
21599 * src/print.c (print_core, print_actions, print_state)
21600 (print_results): Likewise.
21601 * src/print_graph.c (print_core, print_actions, print_state)
21602 (print_graph): Likewise.
21603 * src/conflicts.h: Adjust.
21604
21605 2001-12-27 Akim Demaille <akim@epita.fr>
21606
21607 * src/bison.hairy: Formatting/comment changes.
21608 ANSIfy.
21609 Remove `register' indications.
21610 Add plenty of `static'.
21611
21612 2001-12-27 Akim Demaille <akim@epita.fr>
21613
21614 * src/output.c (prepare): Drop the muscle `ntbase' which
21615 duplicates ntokens.
21616 * src/bison.simple: Formatting/comment changes.
21617 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
21618 is an undocumented synonym.
21619
21620 2001-12-22 Akim Demaille <akim@epita.fr>
21621
21622 * src/output.c (output_table_data): Change the prototype to use
21623 `int' for array ranges: some invocations do pass an int, not a
21624 short.
21625 Reported by Wayne Green.
21626
21627 2001-12-22 Akim Demaille <akim@epita.fr>
21628
21629 Some actions of web2c.y are improperly triggered.
21630 Reported by Mike Castle.
21631
21632 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
21633 * tests/regression.at (Web2c): Rename as...
21634 (Web2c Report): this.
21635 (Web2c Actions): New.
21636
21637 2001-12-22 Akim Demaille <akim@epita.fr>
21638
21639 Reductions in web2c.y are improperly reported.
21640 Reported by Mike Castle.
21641
21642 * src/conflicts.c (print_reductions): Fix.
21643 * tests/regression.at (Web2c): New.
21644
21645 2001-12-18 Akim Demaille <akim@epita.fr>
21646
21647 Some host fail on `assert (!"foo")', which expands to
21648 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
21649 Reported by Nelson Beebee.
21650
21651 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
21652 `#define it_succeeded 0' and `assert (it_succeeded)'.
21653
21654 2001-12-17 Marc Autret <autret_m@epita.fr>
21655
21656 * src/bison.simple: Don't hard code the skeleton line and filename.
21657 * src/output.c (output_parser): Rename 'line' as 'output_line'.
21658 New line counter 'skeleton_line' (skeleton-line muscle).
21659
21660 2001-12-17 Paul Eggert <eggert@twinsun.com>
21661
21662 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
21663 YYDEBUG must be defined to a nonzero value.
21664
21665 * src/bison.simple (yytname): Do not assume that the user defines
21666 YYDEBUG to a properly parenthesized expression.
21667
21668 2001-12-17 Akim Demaille <akim@epita.fr>
21669
21670 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
21671 nlookaheads is a new member.
21672 Adjust all users.
21673 * src/lalr.h (nlookaheads): Remove this orphan declaration.
21674 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
21675 state.
21676
21677 2001-12-17 Akim Demaille <akim@epita.fr>
21678
21679 * src/files.h, src/files.c (open_files, close_files): Remove.
21680 * src/main.c (main): Don't open/close files, nor invoke lex_free,
21681 let...
21682 * src/reader.c (reader): Do it.
21683
21684 2001-12-17 Akim Demaille <akim@epita.fr>
21685
21686 * src/conflicts.c (print_reductions): Formatting changes.
21687
21688 2001-12-17 Akim Demaille <akim@epita.fr>
21689
21690 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
21691 (flush_reduce): New.
21692 (resolve_sr_conflict): Adjust.
21693
21694 2001-12-17 Akim Demaille <akim@epita.fr>
21695
21696 * src/output.c (output_obstack): Be static and rename as...
21697 (format_obstack): this, to avoid any confusion with files.c's
21698 output_obstack.
21699 * src/reader.h (muscle_obstack): Move to...
21700 * src/output.h: here, since it's defined in output.c.
21701
21702 2001-12-17 Akim Demaille <akim@epita.fr>
21703
21704 * src/output.c (action_row, save_column, default_goto)
21705 (sort_actions, matching_state, pack_vector): Better variable
21706 locality.
21707
21708 2001-12-17 Akim Demaille <akim@epita.fr>
21709
21710 * src/output.c: Various formatting changes.
21711
21712 2001-12-17 Akim Demaille <akim@epita.fr>
21713
21714 * src/files.c (output_files): Free the output_obstack.
21715 * src/main.c (main): Call print and print_graph conditionally.
21716 * src/print.c (print): Work unconditionally.
21717 * src/print_graph.c (print_graph): Work unconditionally.
21718 * src/conflicts.c (log_resolution): Output only if verbose_flag.
21719
21720 2001-12-16 Marc Autret <autret_m@epita.fr>
21721
21722 * src/output.c (actions_output): Fix. When we use %no-lines,
21723 there is one less line per action.
21724
21725 2001-12-16 Marc Autret <autret_m@epita.fr>
21726
21727 * src/bison.simple: Remove a useless #line directive.
21728 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
21729 * src/output.c (get_lines_number): New.
21730 (output_parser): Adjust, now takes care about the lines of a
21731 output muscles.
21732 Fix line numbering.
21733 (actions_output): Computes the number of lines taken by actions.
21734 (output_master_parser): Insert new skeleton which is the name of
21735 the output parser file name.
21736
21737 2001-12-15 Marc Autret <autret_m@epita.fr>
21738
21739 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
21740
21741 2001-12-15 Marc Autret <autret_m@epita.fr>
21742
21743 * src/output.c (output_gram): Keep track of the hairy one.
21744
21745 2001-12-15 Akim Demaille <akim@epita.fr>
21746
21747 Make `make distcheck' work.
21748
21749 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
21750 system.h which uses libgettext.h.
21751
21752 2001-12-15 Akim Demaille <akim@epita.fr>
21753
21754 * src/nullable.c (set_nullable): Useless rules must be skipped,
21755 otherwise, since we range over their symbols, we might look at a
21756 nonterminal which no longer ``exists'', i.e., it is not counted in
21757 `nvars', hence we overflow our arrays.
21758
21759 2001-12-15 Akim Demaille <akim@epita.fr>
21760
21761 The header can also be produced directly, without any obstack!
21762 Yahoo!
21763
21764 * src/files.c, src/files.h (defines_obstack): Remove.
21765 (compute_header_macro): Global.
21766 (defines_obstack_save): Remove.
21767 * src/reader.c (parse_union_decl): No longer output to
21768 defines_obstack: its content can be found in the `stype' muscle
21769 anyway.
21770 (output_token_translations): Merge into...
21771 (symbols_output): this.
21772 Rename as...
21773 (symbols_save): this.
21774 (reader): Adjust.
21775 * src/output.c (header_output): New.
21776 (output): Call it.
21777
21778 2001-12-15 Akim Demaille <akim@epita.fr>
21779
21780 * src/reader.c (parse_union_decl): Instead of handling two obstack
21781 simultaneously, use one to define the `stype' muscle, and use the
21782 value of the latter to fill defines_obstack.
21783 (copy_comment): Remove.
21784 (copy_comment2): Work for a single obstack.
21785 Rename as...
21786 (copy_comment): this.
21787
21788 2001-12-15 Akim Demaille <akim@epita.fr>
21789
21790 * src/lex.c, src/lex.h (xgetc): No longer static.
21791 * src/reader.c (parse_union_decl): Revamp.
21792
21793 2001-12-15 Akim Demaille <akim@epita.fr>
21794
21795 Still making progress in separating Bison into (i) input, (ii)
21796 process, (iii) output: now we can directly output the parser file
21797 without using table_obstack at all.
21798
21799 * src/files.c, src/files.h (table_obstack): Bye bye.
21800 (parser_file_name): New.
21801 * src/files.c (compute_output_file_names): Compute it.
21802 * src/output.c (actions_output, output_parser)
21803 (output_master_parser): To a file instead of an obstack.
21804
21805 2001-12-15 Akim Demaille <akim@epita.fr>
21806
21807 Attach actions to rules, instead of pre-outputting them to
21808 actions_obstack.
21809
21810 * src/gram.h (rule_t): action and action_line are new members.
21811 * src/reader.c (symbol_list): Likewise.
21812 (copy_action): Save the actions within the rule.
21813 (packgram): Save them in rule_table.
21814 * src/output.c (actions_output): New.
21815 (output_parser): Use it on `%%actions'.
21816 (output_rule_data): Don't free rule_table.
21817 (output): Do it.
21818 (prepare): Don't save the `action' muscle.
21819 * src/bison.simple: s/%%action/%%actions/.
21820
21821 2001-12-15 Akim Demaille <akim@epita.fr>
21822
21823 * src/reader.c (copy_action): When --yacc, don't append a `;'
21824 to the user action: let it fail if lacking.
21825 Suggested by Arnold Robbins and Tom Tromey.
21826
21827 2001-12-14 Akim Demaille <akim@epita.fr>
21828
21829 * src/lex.c (literalchar): Simply return the char you decoded, non
21830 longer mess around with obstacks and int pointers.
21831 Adjust all callers.
21832
21833 2001-12-14 Akim Demaille <akim@epita.fr>
21834
21835 * src/lex.c (literalchar): Don't escape the special characters,
21836 just decode them, and keep them as char (before, eol was output as
21837 the 2 char string `\n' etc.).
21838 * src/output.c (output_rule_data): Use quotearg to output the
21839 token strings.
21840
21841 2001-12-13 Paul Eggert <eggert@twinsun.com>
21842
21843 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
21844 Do not infringe on the global user namespace when using C++.
21845 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
21846 All uses of `fprintf' and `stderr' changed.
21847
21848 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
21849
21850 2001-12-13 Akim Demaille <akim@epita.fr>
21851
21852 The computation of nullable is broken: it doesn't handle empty
21853 RHS's properly.
21854
21855 * tests/torture.at (GNU AWK Grammar): New.
21856 * tests/sets.at (Nullable): New.
21857 * src/nullable.c (set_nullable): Instead of blindly looping over
21858 `ritems', loop over the rules, and then over their rhs's.
21859
21860 Work around Autotest bugs.
21861
21862 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
21863 frame, because Autotest understand lines starting with a `+' as
21864 traces from the shell. Then, they are not processed properly.
21865 Admittedly an Autotest bug, but we don't have time to wait for
21866 Autotest to catch up.
21867 * tests/regression.at (Broken Closure): Adjust to the new table
21868 frames.
21869 Move to...
21870 * tests/sets.at: here.
21871
21872 2001-12-13 Akim Demaille <akim@epita.fr>
21873
21874 * src/closure.c (closure): Use nrules instead of playing tricks
21875 with BITS_PER_WORD.
21876
21877 2001-12-13 Akim Demaille <akim@epita.fr>
21878
21879 * src/print.c (print_actions): Output the handling of `$' as the
21880 traces do: shifting the token EOF. Before EOF was treated as a
21881 nonterminal.
21882 * tests/regression.at: Adjust some tests.
21883 * src/print_graph.c (print_core): Complete the set of items via
21884 closure. The next-to-final and final states are still unsatisfying,
21885 but that's to be addressed elsewhere.
21886 No longer output the rule numbers, but do output the state number.
21887 A single loop for the shifts + gotos is enough, but picked a
21888 distinct color for each.
21889 (print_graph): Initialize and finalize closure.
21890
21891 2001-12-13 Akim Demaille <akim@epita.fr>
21892
21893 * src/reader.c (readgram): Remove dead code, an strip useless
21894 braces.
21895 (get_type): Remove, unused.
21896
21897 2001-12-12 Akim Demaille <akim@epita.fr>
21898
21899 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
21900 on that of lib/error.c.
21901
21902 2001-12-12 Akim Demaille <akim@epita.fr>
21903
21904 Some hosts don't like `/' in includes.
21905
21906 * src/system.h: Include libgettext.h without qualifying the path.
21907 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
21908 $(top_srcdir).
21909
21910 2001-12-11 Marc Autret <autret_m@epita.fr>
21911
21912 * src/output.c (output_parser): Remove useless muscle.
21913
21914 2001-12-11 Marc Autret <autret_m@epita.fr>
21915
21916 * src/bison.simple: Remove #line just before %%epilogue. It
21917 is now handled in ...
21918 * src/reader.c (read_additionnal_code): Add the output of a
21919 #line for the epilogue.
21920
21921 2001-12-10 Marc Autret <autret_m@epita.fr>
21922
21923 * src/reader.c (copy_definition): Re-use CPP-outed code which
21924 replace precedent remove.
21925 * src/bison.simple: Remove #line before %%prologue because
21926 %%input-line is wrong at this time.
21927
21928 2001-12-10 Marc Autret <autret_m@epita.fr>
21929
21930 * src/reader.c (symbols_output): Clean up.
21931 * src/output.c (output_gram, output): Clean up.
21932
21933 2001-12-10 Akim Demaille <akim@epita.fr>
21934
21935 * src/lalr.c (initialize_lookaheads): New. Extracted from...
21936 * src/LR0.c (set_state_table): here.
21937 * src/lalr.c (lalr): Call it.
21938
21939 2001-12-10 Akim Demaille <akim@epita.fr>
21940
21941 * src/state.h (shifts): Remove the `number' member: shifts are
21942 attached to state, hence no longer need to be labelled with a
21943 state number.
21944
21945 2001-12-10 Akim Demaille <akim@epita.fr>
21946
21947 Now that states have a complete set of members, the linked list of
21948 shifts is useless: just fill directly the state's shifts member.
21949
21950 * src/state.h (shifts): Remove the `next' member.
21951 * src/LR0.c (first_state, last_state): Remove.
21952 Adjust the callers.
21953 (augment_automaton): Don't look for the shifts that must be added
21954 a shift on EOF: it is those of the state we looked for! But now,
21955 since shifts are attached, it is no longer needed to looking
21956 merely by its id: its number.
21957
21958 2001-12-10 Akim Demaille <akim@epita.fr>
21959
21960 * src/LR0.c (augment_automaton): Better variable locality.
21961 Remove an impossible branch: if there is a state corresponding to
21962 the start symbol being shifted, then there is shift for the start
21963 symbol from the initial state.
21964
21965 2001-12-10 Akim Demaille <akim@epita.fr>
21966
21967 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
21968 only when appropriate: when insert_start_shifting_state' is not
21969 invoked.
21970 * tests/regression.at (Rule Line Numbers): Adjust.
21971
21972 2001-12-10 Akim Demaille <akim@epita.fr>
21973
21974 * src/LR0.c (augment_automaton): Now that all states have shifts,
21975 merge the two cases addition shifts to the initial state.
21976
21977 2001-12-10 Akim Demaille <akim@epita.fr>
21978
21979 * src/lalr.c (set_state_table): Move to...
21980 * src/LR0.c: here.
21981 * src/lalr.c (lalr): Don't call it...
21982 * src/LR0.c (generate_states): do it.
21983 * src/LR0.h (first_state): Remove, only the table is used.
21984
21985 2001-12-10 Akim Demaille <akim@epita.fr>
21986
21987 * src/LR0.h (first_shift, first_reduction): Remove.
21988 * src/lalr.c: Don't use first_shift: find shifts through the
21989 states.
21990
21991 2001-12-10 Akim Demaille <akim@epita.fr>
21992
21993 * src/LR0.c: Attach shifts to states as soon as they are
21994 computed.
21995 * src/lalr.c (set_state_table): Instead of assigning shifts to
21996 state, just assert that the mapping was properly done.
21997
21998 2001-12-10 Akim Demaille <akim@epita.fr>
21999
22000 * src/LR0.c (insert_start_shift): Rename as...
22001 (insert_start_shifting_state): this.
22002 (insert_eof_shifting_state, insert_accepting_state): New.
22003 (augment_automaton): Adjust.
22004 Better locality of the variables.
22005 When looking if the start_symbol is shifted from the initial
22006 state, using `while (... symbol != start_symbol ...)' sounds
22007 better than `while (... symbol < start_symbol ...)': If fail
22008 to see how the order between symbols could be relevant!
22009
22010 2001-12-10 Akim Demaille <akim@epita.fr>
22011
22012 * src/getargs.h: Don't declare `spec_name_prefix' and
22013 `spec_file_prefix', declared by src/files.h.
22014 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
22015 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
22016 * src/output.c (prepare): Adjust.
22017 * src/reader.c (symbols_output): Likewise.
22018 * src/vmsgetargs.c: Vaguely adjust, but who cares?
22019
22020 2001-12-10 Akim Demaille <akim@epita.fr>
22021
22022 * src/muscle_tab.c (muscle_init): NULL is a better default than
22023 `"0"'.
22024
22025 2001-12-10 Akim Demaille <akim@epita.fr>
22026
22027 * src/reader.c (reader): Calling symbols_output once is enough.
22028
22029 2001-12-10 Akim Demaille <akim@epita.fr>
22030
22031 Now that states have a complete set of members, the linked list of
22032 reductions is useless: just fill directly the state's reductions
22033 member.
22034
22035 * src/state.h (struct reductions): Remove member `number' and
22036 `next'.
22037 * src/LR0.c (first_reduction, last_reduction): Remove.
22038 (save_reductions): Don't link the new reductions, store them in
22039 this_state.
22040 * src/lalr.c (set_state_table): No need to attach reductions to
22041 states, it's already done.
22042 * src/output.c (output_actions): No longer free the shifts, then
22043 the reductions, then the states: free all the states and their
22044 members.
22045
22046 2001-12-10 Akim Demaille <akim@epita.fr>
22047
22048 * src/options.c (OPTN, DRTV, BOTH): New.
22049 (option_table): Use them.
22050
22051 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
22052 the job of system.h.
22053 * src/options.c: Don't include stdio.h and xalloc.h for the same
22054 reasons.
22055
22056 2001-12-10 Akim Demaille <akim@epita.fr>
22057
22058 * src/output.c (output, prepare): Make sure the values of the
22059 muscles `action' and `prologue' are 0-terminated.
22060
22061 2001-12-10 Akim Demaille <akim@epita.fr>
22062
22063 Clean up GCC warnings.
22064
22065 * src/reader.c (copy_action): `buf' is not used.
22066 (parse_skel_decl): Be static.
22067 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
22068 * src/options.h (create_long_option_table): Have a real prototype.
22069 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
22070 (hash_delete_at): Return const void *.
22071 Adjust casts to preserve the const.
22072
22073 2001-12-10 Akim Demaille <akim@epita.fr>
22074
22075 * configure.in: Require 2.52g.
22076 M4 is not needed, but AUTOM4TE is.
22077 * m4/m4.m4: Remove.
22078 * tests/Makefile.am: Adjust.
22079
22080 2001-12-10 Akim Demaille <akim@epita.fr>
22081
22082 One structure for states is enough, even though theoretically
22083 there are LR(0) states and LALR(1) states.
22084
22085 * src/lalr.h (state_t): Remove.
22086 (state_table): Be state_t **, not state_t *.
22087 * src/state.h (core, CORE_ALLOC): Rename as...
22088 (state_t, STATE_ALLOC): this.
22089 Add the LALR(1) members: shifts, reductions, errs.
22090 * src/LR0.c (state_table): Rename as...
22091 (state_hash): this, to avoid name clashes with the global
22092 `state_table'.
22093 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
22094 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
22095
22096 2001-12-10 Akim Demaille <akim@epita.fr>
22097
22098 Bison dumps core on bash.y.
22099 Reported by Pascal Bart.
22100
22101 * src/warshall.c (bitmatrix_print): New.
22102 (TC): Use it.
22103 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
22104 j must be the outer loop.
22105 * tests/regression.at (Broken Closure): New.
22106
22107 2001-12-05 Akim Demaille <akim@epita.fr>
22108
22109 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
22110 its argument.
22111 Reported by Peter Hamorsky.
22112
22113 2001-12-05 Akim Demaille <akim@epita.fr>
22114
22115 * src/conflicts.c (err_table): Remove.
22116 (resolve_sr_conflict): Adjust.
22117 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
22118 Rename as...
22119 (state_t.reductions, state_t.shifts): this.
22120
22121 2001-12-05 Akim Demaille <akim@epita.fr>
22122
22123 * src/reduce.c (reduce_grammar_tables): No longer disable the
22124 removal of useless rules via CPP but via `if (0)', so that the
22125 compiler still check the code is valid.
22126 For instance, it should have noticed `rline' no longer exists: use
22127 the `line' member of rule_t.
22128 * src/gram.c (dummy, rline): Remove, unused.
22129
22130 2001-12-05 Akim Demaille <akim@epita.fr>
22131
22132 * src/output.c (pack_vector): Use assert, not berror.
22133 * src/main.c (berror): Remove, unused.
22134
22135 2001-12-05 Akim Demaille <akim@epita.fr>
22136
22137 New experimental feature: if --verbose --trace output all the
22138 items of a state, not only its kernel.
22139
22140 * src/print.c (print_core): If `trace_flag', then invoke closure
22141 before outputting the items of the state (print_core is no longer
22142 a correct name them).
22143 (print_results): Invoke new_closure/free_closure if needed.
22144
22145 2001-12-05 Akim Demaille <akim@epita.fr>
22146
22147 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
22148 * src/closure.c, src/closure.h (itemsetsize): Rename as...
22149 (nitemset): for consistency with the rest of the project.
22150
22151 2001-12-05 Akim Demaille <akim@epita.fr>
22152
22153 * src/closure.c (print_closure): Improve.
22154 (closure): Use it for printing input and output.
22155
22156 2001-12-05 Akim Demaille <akim@epita.fr>
22157
22158 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
22159 indexed by nonterminals.
22160
22161 2001-12-05 Akim Demaille <akim@epita.fr>
22162
22163 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
22164 what it was!).
22165 * src/warshall.h: Remove accidental duplication of the content.
22166
22167 2001-12-05 Akim Demaille <akim@epita.fr>
22168
22169 * src/closure.c (set_fderives): De-obfuscate.
22170
22171 2001-12-05 Akim Demaille <akim@epita.fr>
22172
22173 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
22174
22175 2001-12-05 Akim Demaille <akim@epita.fr>
22176
22177 * src/closure.c (set_firsts): De-obfuscate.
22178
22179 2001-12-05 Akim Demaille <akim@epita.fr>
22180
22181 * src/output.c (action_row): De-obfuscate
22182 using the good o' techniques: arrays not pointers, variable
22183 locality, BITISSET, RESETBIT etc.
22184
22185 2001-12-05 Akim Demaille <akim@epita.fr>
22186
22187 Pessimize the code to simplify it: from now on, all the states
22188 have a valid SHIFTS, which NSHIFTS is possibly 0.
22189
22190 * src/LR0.c (shifts_new): Be global and move to..
22191 * src/state.c, src/state.h: here.
22192 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
22193 * src/print_graph: Adjust.
22194
22195 2001-12-05 Akim Demaille <akim@epita.fr>
22196
22197 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
22198 * src/conflicts.c: Use it.
22199 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
22200 incorrectly ``simplified''.
22201
22202 2001-12-05 Akim Demaille <akim@epita.fr>
22203
22204 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
22205 using the good o' techniques: arrays not pointers, variable
22206 locality, BITISSET, RESETBIT etc.
22207
22208 2001-12-05 Akim Demaille <akim@epita.fr>
22209
22210 * src/state.h (SHIFT_SYMBOL): New.
22211 * src/conflicts.c: Use it to deobfuscate.
22212
22213 2001-12-05 Akim Demaille <akim@epita.fr>
22214
22215 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
22216 (print_reductions): De-obfuscate using the good o' techniques:
22217 arrays not pointers, variable locality, BITISSET.
22218
22219 2001-12-05 Akim Demaille <akim@epita.fr>
22220
22221 * src/conflicts.c (print_reductions): Arrays, not pointers.
22222 Use BITISSET.
22223
22224 2001-12-05 Akim Demaille <akim@epita.fr>
22225
22226 * src/conflicts.c (print_reductions): Pessimize, but clarify.
22227
22228 2001-12-05 Akim Demaille <akim@epita.fr>
22229
22230 * src/conflicts.c (print_reductions): Improve variable locality.
22231
22232 2001-12-05 Akim Demaille <akim@epita.fr>
22233
22234 * src/conflicts.c (print_reductions): Pessimize, but clarify.
22235
22236 2001-12-05 Akim Demaille <akim@epita.fr>
22237
22238 * src/conflicts.c (print_reductions): Improve variable locality.
22239
22240 2001-12-05 Akim Demaille <akim@epita.fr>
22241
22242 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
22243 * src/lalr.c: Use them.
22244
22245 2001-12-05 Akim Demaille <akim@epita.fr>
22246
22247 * src/LR0.c (augment_automaton): Formatting changes.
22248 Better variable locality.
22249
22250 2001-12-05 Akim Demaille <akim@epita.fr>
22251
22252 * src/lalr.c (matrix_print): New.
22253 (transpose): Use it.
22254 Use arrays instead of pointers.
22255
22256 2001-12-05 Akim Demaille <akim@epita.fr>
22257
22258 * src/lalr.c (maxrhs): Move to...
22259 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
22260 * src/lalr.c (build_relations): Adjust.
22261
22262 2001-12-05 Akim Demaille <akim@epita.fr>
22263
22264 * src/lalr.c (transpose): Free the memory allocated to the
22265 argument, as it is replaced by the results by the unique caller.
22266 (build_relations): Merely invoke transpose: it handles the memory
22267 deallocation.
22268 Improve variable locality.
22269 Avoid variables used as mere abbreviations.
22270 (compute_lookaheads): Use arrays instead of pointers.
22271
22272 2001-12-05 Akim Demaille <akim@epita.fr>
22273
22274 * src/lalr.c (initialize_F): Improve variable locality.
22275 Avoid variables used as mere abbreviations.
22276
22277 2001-12-05 Akim Demaille <akim@epita.fr>
22278
22279 * src/derives.c (print_derives): Display the ruleno.
22280 * src/lalr.c (initialize_F, transpose): Better variable locality
22281 to improve readability.
22282 Avoid variables used as mere abbreviations.
22283
22284 2001-12-05 Akim Demaille <akim@epita.fr>
22285
22286 * src/lalr.c (traverse): Use arrays instead of pointers.
22287
22288 2001-12-05 Akim Demaille <akim@epita.fr>
22289
22290 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
22291 the handling of squeue.
22292 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
22293
22294 2001-12-05 Akim Demaille <akim@epita.fr>
22295
22296 Because useless nonterminals are now kept alive (instead of being
22297 `destroyed'), we now sometimes examine them, and store information
22298 related to them. Hence we need to know their number, and adjust
22299 memory allocations.
22300
22301 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
22302 static.
22303 * src/LR0.c (allocate_itemsets): The memory allocated to
22304 `symbol_count' was used for two different purpose: once to count
22305 the number of occurrences of each symbol, and later reassigned to
22306 `shift_symbol', containing the symbol that can be shifted from a
22307 given state.
22308 Deobfuscate, i.e., allocate, use and free `symbol_count' here
22309 only, and...
22310 (new_itemsets): Allocate `shift_symbol' here.
22311 (allocate_itemsets): symbol_count includes useless nonterminals.
22312 Make room for them.
22313 (free_storage): Use `free', not `XFREE', for pointers that cannot
22314 be null.
22315

22318 * src/nullable.c (set_nullable): Deobfuscate the handling of
22319 ritem.
22320 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
22321
22322 2001-12-05 Akim Demaille <akim@epita.fr>
22323
22324 * src/gram.c, src/gram.h (ritem_print): New.
22325 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
22326 (This useless function was defined only to work around VMS linkers
22327 that can't handle compilation units with variables only).
22328 * src/reduce.c (dump_grammar): Use it to trace the construction of
22329 ritem.
22330
22331 2001-12-04 Paul Eggert <eggert@twinsun.com>
22332
22333 * src/bison.simple (union yyalloc): Change member names
22334 to be the same as the stack names.
22335 (yyparse): yyptr is now union yyalloc *, not char *.
22336 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
22337 and may generate better code on some machines.
22338 (yystpcpy): Use prototype if __STDC__ is defined, not just
22339 if __cplusplus is defined.
22340
22341 2001-11-30 Akim Demaille <akim@epita.fr>
22342
22343 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
22344 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
22345 Gettext doesn't compile cleanly, and dies with -Werror.
22346 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
22347 Include WARNING_CFLAGS here.
22348 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
22349 before being defined.
22350
22351 2001-11-27 Paul Eggert <eggert@twinsun.com>
22352
22353 * lib/quotearg.h (quotearg_n, quotearg_n_style):
22354 First arg is int, not unsigned.
22355 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
22356 (SIZE_MAX, UINT_MAX): New macros.
22357 (quotearg_n_options): Abort if N is negative.
22358 Avoid overflow check on hosts where size_t is 64 bits and int
22359 is 32 bits, as overflow is impossible there.
22360 Fix off-by-one typo that caused unnecessary reallocation.
22361
22362 2001-11-29 Paul Eggert <eggert@twinsun.com>
22363
22364 Name space cleanup in generated parser.

22370 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
22371 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
22372 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
22373
22374 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
22375 on user names when possible.
22376
22377 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
22378 Simplify test for whather <alloca.h> exists.
22379
22380 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
22381
22382 (<stdio.h>): Include if YYDEBUG.
22383
22384 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
22385 ! defined (yyoverflow) && ! defined (yymemcpy).
22386
22387 (yymemcpy, yyparse): Rename local variables as needed so that
22388 they all begin with 'yy'.
22389
22390 (yystrlen, yystpcpy): New functions.
22391
22392 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
22393 All uses changed.
22394
22395 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
22396 instead of relying on string.h functions. Use YYSTACK_ALLOC
22397 and YYSTACK_FREE instead of malloc and free.
22398
22399 2001-11-30 Akim Demaille <akim@epita.fr>

22409 2001-11-30 Akim Demaille <akim@epita.fr>
22410
22411 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty

22413
22414 2001-11-30 Akim Demaille <akim@epita.fr>
22415
22416 Instead of mapping the LHS of unused rules to -1, keep the LHS
22417 valid, but flag the rules as invalid.
22418
22419 * src/gram.h (rule_t): `useful' is a new member.
22420 * src/print.c (print_grammar): Adjust.
22421 * src/derives.c (set_derives): Likewise.
22422 * src/reader.c (packgram, reduce_output): Likewise.

22427
22428 * src/reduce.c (reduce_output): Formatting changes.
22429 * src/print.c (print_results, print_grammar): Likewise.
22430 * tests/regression.at (Rule Line Numbers)
22431 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
22432
22433 2001-11-30 Akim Demaille <akim@epita.fr>
22434
22435 * src/reduce.c (nonterminals_reduce): Instead of throwing away
22436 useless nonterminals, move them at the end of the symbol arrays.
22437 (reduce_output): Adjust.
22438 * tests/reduce.at (Useless Nonterminals): Adjust.
22439
22440 2001-11-30 Akim Demaille <akim@epita.fr>
22441
22442 * src/reduce.c: Various comment/formatting changes.
22443 (nonterminals_reduce): New, extracted from...
22444 (reduce_grammar_tables): here.

22450 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
22451 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
22452 New macros.
22453 (union yyalloc): New type.
22454 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
22455 an arbitrary restriction on hosts where size_t is wider than int.
22456
22457 (yyparse): Don't dump core if alloca or malloc fails; instead, report
22458 a parser stack overflow. Allocate just one block of memory for all
22459 three stacks, instead of allocating three blocks; this typically is
22460 faster and reduces fragmentation.
22461
22462 Do not limit the number of items in the stack to a value that fits
22463 in 'int', as this is an arbitrary limit on hosts with 64-bit
22464 size_t and 32-bit int.
22465
22466 2001-11-29 Marc Autret <autret_m@epita.fr>

22525
22526 * src/closure.c (closure): No longer optimize the special case

22530 2001-11-28 Akim Demaille <akim@epita.fr>
22531
22532 * src/closure.c (closure): `r' and `c' are new variables, used to

22761 Output consistently TRACEs to stderr, not stdout.
22762 * src/derives.c: Likewise.
22763 * src/reduce.c: (inaccessable_symbols): Using if is better style
22764 than goto.
22765 Use `#if TRACE' instead of `#if 0' for tracing code.
22766
22767 2001-11-19 Akim Demaille <akim@epita.fr>

22790
22791 2001-11-19 Akim Demaille <akim@epita.fr>
22792
22793 * src/vcg.c: You do the output, so you are responsible of the
22794 handling of VCG syntax, in particular: use quotearg.
22795 * src/print_graph.c: Don't.
22796 (print_actions): Don't output the actions as part of the nodes,
22797 since that's the job of the edges.

22890
22891 * tests/calc.at, tests/output.at, tests/regression.at,
22892 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
22893 now the tests are run in private dirs, therefore AC_CLEANUP and
22894 family can be simplified to 0-ary.
22895 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
22896 use abs. path to find config.h.
22897 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
22898 stderr, there can be way too much random noise.
22899 Instead pass -Werror to GCC and rely on the exit status.
22900 Reported by Wolfram Wagner.
22901
22902 2001-11-14 Akim Demaille <akim@epita.fr>
22903
22904 * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be

22913
22914 2001-11-14 Akim Demaille <akim@epita.fr>
22915
22916 * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):

22919 braces to pacify GCC's warnings for `if () if () {} else {}'.
22920 * src/lex.c (parse_percent_token): Replace equal_offset with
22921 arg_offset.
22922 arg is const.

22973 (reduce_free): New.
22974 Also free V1.

23021 with yyltype/YYLTYPE. This allows inclusion of the generated
23022 header within the parser if the compiler, such as GGC, accepts
23023 multiple equivalent #defines.

24268
24269 * src/conflicts.c (conflict_report): Be sure not to append to res

24276 New, from fileutils 4.0.37.
24277 * configure.in: Require Autoconf 2.49c. I took some time before
24278 making this decision. This is the only way out for portability
24279 issues in Bison, it would mean way too much duplicate effort to
24280 import in Bison features implemented in 2.49c since 2.13.
24281 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
24282

24297
24298 2001-01-19 Akim Demaille <akim@epita.fr>
24299
24300 * src/lex.h: Rename all the tokens:
24301 s/\bENDFILE\b/tok_eof/g;
24302 s/\bIDENTIFIER\b/tok_identifier/g;
24303 etc.
24304 Let them be enums, not #define, to ease debugging.
24305 Adjust all the code.
24306
24307 2001-01-18 Akim Demaille <akim@epita.fr>
24308

24314 Since we now use obstacks, more % directives can be enabled.
24315
24316 * src/lex.c (percent_table): Also accept `%yacc',
24317 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

24320 instead of returning a token.
24321 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
24322 * src/reader.c (read_declarations): Adjust.
24323 * src/files.c (open_files): Don't call `compute_base_names', don't
24324 compute `attrsfile' since they depend upon data which might be
24325 *in* the input file now.
24326 (output_files): Do it here.
24327 * src/output.c (output_headers): Document the fact that this patch
24328 introduces a guaranteed SEGV for semantic parsers.
24329 * doc/bison.texinfo: Document them.
24330 * tests/suite.at: Exercise these %options.
24331

24350
24351 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

24353 FILE * parameters.
24354
24355 2000-12-20 Akim Demaille <akim@epita.fr>
24356
24357 * src/files.c (open_files): Actually the `.output' file is based
24358 on the short_base_name, not base_name.

24360
24361 2000-12-20 Akim Demaille <akim@epita.fr>

24383
24384 2000-12-19 Akim Demaille <akim@epita.fr>
24385
24386 * src/files.c (strsuffix): New.
24387 (stringappend): Be just like strcat but allocate.
24388 (base_names): Eve out from open_files.
24389 Try to simplify the rather hairy computation of base_name and
24390 short_base_name.
24391 (open_files): Use it.
24392 * tests/suite.at (Checking output file names): New test.
24393

24429
24430 2000-12-19 Akim Demaille <akim@epita.fr>
24431
24432 * src/files.c (open_files): Yipee! We no longer need all the code
24433 looking for `/tmp' since we have no tmp file.
24434
24435 2000-12-19 Akim Demaille <akim@epita.fr>
24436

24466 prevents type checking.
24467 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
24468 cast the value to (void *): assigning a `foo *' to a `void *'
24469 variable is valid.

24471 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

24526
24527 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

24532
24533 For some reason, this was not applied.

24549 (output_files): this.
24550 Use `obstack_save'.
24551 * src/main.c (main): Don't use `atexit' to register `done', since
24552 it no longer has to remove tmp files, just call `output_files'
24553 when there are no errors.

24626 the `/' which is suspected to open a comment, instead of being
24627 called after `//' or `/*' was read.
24628 (copy_comment, copy_definition, parse_union_decl, copy_action)
24629 (copy_guard): Adjust.
24630
24631 2000-10-16 Akim Demaille <akim@epita.fr>
24632
24633 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
24634 `read_signed_integer'.
24635
24636 2000-10-16 Akim Demaille <akim@epita.fr>

24656
24657 2000-10-04 Akim Demaille <akim@epita.fr>
24658
24659 When a literal string is used to define two different tokens,
24660 `bison -v' segfaults.
24661 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
24662

24671 of `buffer'.
24672 From Neil Booth.
24673
24674 2000-10-02 Paul Eggert <eggert@twinsun.com>
24675
24676 * bison.s1 (yyparse): Assign the default value
24677 unconditionally, to avoid a GCC warning and make the parser a
24678 tad smaller.
24679
24680 2000-10-02 Akim Demaille <akim@epita.fr>
24681
24682 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
24683 options.
24684
24685 2000-10-02 Akim Demaille <akim@epita.fr>
24686
24687 * src/derives.c, src/print.c, src/reduce.c: To ease the
24688 translation, move some `\n' out of the translated strings.
24689
24690 2000-10-02 Akim Demaille <akim@epita.fr>
24691
24692 The location tracking mechanism is precious for parse error
24693 messages. Nevertheless, it is enabled only when `@n' is used in
24694 the grammar, which is a different issue (you can use it in error
24695 message, but not in the grammar per se). Therefore, there should
24696 be another means to enable it.
24697
24698 * src/getargs.c (getargs): Support `--locations'.
24699 (usage): Report it.
24700 * src/getargs.h (locationsflag): Export it.
24701 * src/lex.c (percent_table): Support `%locations'.
24702 * src/reader.c (yylsp_needed): Remove this variable, now replaced
24703 with `locationsflag'.
24704 * doc/bison.texinfo: Document `--locations' and `%locations'.
24705 Sort the options.
24706 * tests/calc.m4: Test it.
24707
24708 For regularity of the names, replace each
24709 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
24710 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
24711 In addition replace each `flag' with `_flag'.
24712
24713 2000-10-02 Akim Demaille <akim@epita.fr>
24714
24715 Also test parse error messages, including with YYERROR_VERBOSE.
24716
24717 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
24718 associative).
24719 Use it to check the computations.
24720 Use it to check `nonassoc' is honored.
24721 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
24722 `--yyerror-verbose'.
24723 (_AT_CHECK_CALC): Adjust to this option.
24724 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
24725
24726 2000-10-02 Akim Demaille <akim@epita.fr>
24727
24728 Test also `--verbose', `--defines' and `--name-prefix'. Testing
24729 the latter demonstrates a flaw in the handling of non debugging
24730 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
24731 was used in order to simplify:
24732
24733 #if YYDEBUG
24734 if (yydebug)
24735 {
24736 ...
24737 }
24738 #endif
24739
24740 into
24741
24742 if (yydebug)
24743 {
24744 ...
24745 }
24746
24747 unfortunately this leads to a CPP conflict when
24748 `--name-prefix=foo' is used since it produces `#define yydebug
24749 foodebug'.
24750
24751 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
24752 (YYDPRINTF): New macro.
24753 Spread its use.
24754 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
24755 the bison options.
24756 Also test `--verbose', `--defines' and `--name-prefix'.
24757
24758 2000-10-02 Akim Demaille <akim@epita.fr>
24759
24760 Improve the readability of the produced parsers.
24761
24762 * src/bison.s1: Formatting changes.
24763 Improve the comment related to the `$' mark.
24764 (yydefault): Don't fall through to `yyresume': `goto' there.
24765 * src/output.c (output_parser): When the `$' is met, skip the end
24766 of its line.
24767 New variable, `number_of_dollar_signs', to check there's exactly
24768 one `$' in the parser skeleton.
24769
24770 2000-10-02 Akim Demaille <akim@epita.fr>
24771
24772 * lib/xstrdup.c: New file, from the fileutils.
24773 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
24774 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
24775 instead of strlen + xmalloc + strcpy.
24776 * src/symtab.c (copys): Remove, use xstrdup instead.
24777
24778 2000-10-02 Akim Demaille <akim@epita.fr>
24779
24780 * src/gram.h (associativity): New enum type which replaces the
24781 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
24782 `right_assoc', `left_assoc' and `non_assoc'.
24783 Adjust all dependencies.
24784 * src/reader.c: Formatting changes.
24785 (LTYPESTR): Don't define it, use it as a literal in
24786 `reader_output_yylsp'.
24787 * src/symtab.h (symbol_class): New enum type which replaces the
24788 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
24789 `sunknown', `stoken and `snterm'.
24790
24791 2000-10-02 Akim Demaille <akim@epita.fr>
24792
24793 * src/getargs.c (fixed_outfiles): Rename as...
24794 (yaccflag): for consistency and accuracy.
24795 Adjust dependencies.
24796
24797 2000-10-02 Akim Demaille <akim@epita.fr>
24798
24799 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
24800 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
24801 difficult and introduced a lot of core dump. It turns out that
24802 Bison used an implementation of `xmalloc' based on `calloc', and
24803 at various places it does depend upon the initialization to 0. I
24804 have not tried to isolate the pertinent places, and all the former
24805 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
24806 someone should address this issue.
24807
24808 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
24809 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
24810 files.
24811 Adjust dependencies.

24820
24821 2000-10-02 Akim Demaille <akim@epita.fr>
24822
24823 * src/state.h (nstates, final_state, first_state, first_shift)
24824 (first_reduction): Move their exportation from here...
24825 * src/LR0.h: to here.
24826 Adjust dependencies.
24827 * src/getargs.c (statisticsflag): New variable.
24828 Add support for `--statistics'.

24848
24849 * src/conflicts.c (conflict_report): New function.

24851 (print_conflicts): this function.
24852 Adjust dependencies.
24853 * src/conflicts.h: New file.
24854 Propagate its inclusion.
24855
24856 2000-10-02 Akim Demaille <akim@epita.fr>

24881 * src/reader.h: New file.
24882 Propagate its use instead of tedious list of `extern' and
24883 prototypes.
24884 * src/reader.c: Formatting changes, topological sort,
24885 s/register//.
24886
24887 2000-10-02 Akim Demaille <akim@epita.fr>
24888
24889 * src/lex.h: Prototype `lex.c' exported functions.
24890 * src/reader.c: Adjust.
24891 * src/lex.c: Formatting changes.
24892 (safegetc): Rename as...

24900
24901 2000-10-02 Akim Demaille <akim@epita.fr>
24902
24903 * src/output.c (token_actions): Introduce a temporary array,
24904 YYDEFACT, that makes it possible for this function to use
24905 output_short_table.
24906
24907 2000-10-02 Akim Demaille <akim@epita.fr>
24908
24909 `user_toknums' is output as a `short[]' in `output.c', while it is
24910 defined as a `int[]' in `reader.c'. For consistency with the
24911 other output tables, `user_toknums' is now defined as a table of
24912 shorts.
24913
24914 * src/reader.c (user_toknums): Be a short table instead of an int
24915 table.
24916 Adjust dependencies.
24917
24918 Factor the short table outputs.
24919
24920 * src/output.c (output_short_table): New function.
24921 * src/output.c (output_gram, output_stos, output_rule_data)
24922 (output_base, output_table, output_check): Use it.
24923
24924 2000-10-02 Akim Demaille <akim@epita.fr>

25176 Change the handling of @s so that they behave exactly like $s.
25177 There is now a pseudo variable @$ (readble and writable), location
25178 of the lhs of the rule (by default ranging from the location of
25179 the first symbol of the rhs, to the location of the last symbol,

25215 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

25889 New function.
25890 (readgram): Use `#if 0' around code that accepted %command
25891 inside grammar rules: The documentation doesn't allow it,
25892 and it will fail since the %command processors scan for the next %.
25893 (parse_token_decl): Extended the %token
25894 declaration to allow a multi-character symbol as an alias.
25895 (parse_thong_decl): New function.
25896 (read_declarations): Added %thong declarations.
25897 (read_declarations): Handle NOOP to deal with allowing

25899 (readgram): Allow %prec prior to semantics embedded in a rule.
25900 (skip_to_char, read_declarations, copy_definition)

25904 (get_type, packsymbols): Revised most error messages.
25905 Changed `fatal' to `warnxxx' to avoid aborting for error.
25906 Revised and use multiple warnxxx functions to avoid using VARARGS1.
25907 (read_declarations): Improve the error message for
25908 an invalid character. Do not abort.
25909 (read_declarations, copy_guard, copy_action): Use
25910 printable_version to avoid unprintable characters in printed output.
25911 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
25912 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
25913 Allow the type of a non-terminal can be given
25914 more than once, as long as all specifications give the same type.
25915
25916 * src/output.c:
25917 (output_headers, output_trailers, output, output_gram)
25918 (output_rule_data): Implement noparserflag variable.
25919 Implement toknumflag variable.
25920 (output): Call reader_output_yylsp to output LTYPESTR.
25921
25922 * src/main.c (main):
25923 If reader sees an error, don't process the grammar.
25924 (fatals): Updated to not use VARARGS1.
25925 (printable_version, int_to_string, warn, warni, warns, warnss)
25926 (warnsss): New error reporting functions. Avoid abort for error.
25927
25928 * src/lex.h:
25929 Added THONG and NOOP for alias processing.
25930 Added SETOPT for the new code that allows setting options with %flags.
25931
25932 * src/lex.c:
25933 Include getopt.h. Add some extern decls.
25934 (safegetc): New function to deal with EOF gracefully.
25935 (literalchar); new function to deal with reading \ escapes.
25936 (lex): Use literalchar.
25937 (lex): Implemented "..." tokens.
25938 (literalchar, lex, parse_percent_token): Made tokenbuffer
25939 always contain the token. This includes growing the token
25940 buffer while reading an integer.
25941 (parse_percent_token): Replaced if-else statement with percent_table.
25942 (parse_percent_token): Added % declarations as another
25943 way to specify the flags -n, -l, and -r. Also added hooks for
25944 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
25945 major changes to files.c.
25946 (lex) Retain in the incoming stream a character following
25947 an incorrect '/'.
25948 (skip_white_space, lex): Revised most error messages
25949 and changed fatal to warn to avoid aborting.
25950 (percent_table): Added %thong declarations.
25951
25952 * src/gram.h: Comment changes.
25953
25954 * src/files.c (openfiles, open_extra_files, done):
