2
3 Fix test failure reported by Tom Lane in
4 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
5 and try to make such failures easier to catch in the future.
6 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
7 that's now the caller's responsibility.
8 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
9 Set yychar = YYEOF if it's negative.
10 * tests/actions.at (yylex): Abort if asked to read past EOF.
11 * tests/conflicts.at (yylex): Likewise.
12 * tests/cxx-type.at (yylex): Likewise.
13 * tests/glr-regression.at (yylex): Likewise.
14 * tests/input.at (yylex): Likewise.
15 * tests/regression.at (yylex): Likewise.
16 * tests/torture.at (yylex): Likewise.
17
18 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
19
20 Fix problems with translating English-language diagnostics.
21 * bootstrap: Fix bug introduced in recent bootstrap changes, with
22 respect to bison-runtime pot generation. The YY_ stuff
23 wasn't being captured.
24 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
25 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
26 * runtime-po/POTFILES.in: Add data/push.c.
27
28 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
29
30 Merge bootstrap changes from coreutils.
31
32 2006-09-28 Jim Meyering <jim@meyering.net>
33
34 Automatically generated dependencies are important even
35 when all of the sources in a directory come from gnulib.
36 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
37 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
38
39 2006-09-23 Jim Meyering <jim@meyering.net>
40
41 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
42
43 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
44
45 * bootstrap: Add support for --force.
46 (usage): New function. Describe usage less tersely.
47 (CVS_only_file): New var.
48
49 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
50
51 * data/push.c (YYPUSH_MORE): Make it an enum instead.
52 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
53 Adjust white space and comments to match GNU style better.
54
55 2006-09-20 Bob Rossi <bob@brasko.net>
56
57 * data/push.c (yyresult_get): Remove function.
58 (YYPUSH_MORE): Add #define.
59 (yypushparse): Modify return value.
60
61 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
62
63 * stamp-h.in: Remove; no longer needed.
64 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
65 Remove config.h, config.hin, intl (no longer created).
66 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
67 stamp-h1.
68
69 Sync bootstrap from coreutils, as follows:
70
71 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
72
73 * bootstrap (symlink_to_gnulib): New function.
74 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
75 to copies-of-gnulib.
76 (cp_mark_as_generated, slurp, gnulib_files):
77 Avoid making a copy if it's the same as the old version.
78 (gnulib_files): Add support for this variable (used by Bison).
79
80 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
81
82 * src/getargs.c (usage): Rework to use conventions similar to
83 coreutils, to make translation a bit easier and the code a bit
84 smaller. Problem reported by Tim Van Holder.
85
86 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
87
88 Use some of gnulib's new modules, taken from coreutils.
89
90 * bootstrap: Sync from coreutils, except add support for gnulib_files.
91 * bootstrap.conf: New file.
92 (gnulib_modules): Add configmake, inttypes, unistd.
93 (XGETTEXT_OPTIONS): Add complain, complain_at,
94 fatal, fatal_at, warn, warn_at, unexpected_end.
95 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
96 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
97 (gl_EARLY): Add.
98 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
99 (gl_INIT): Add
100 (GNULIB_AUTOCONF_SNIPPET): Remove.
101 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
102 the pickiest.
103 * lib/.cvsignore: Add inttypes_.h.
104 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
105 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
106 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
107 no-longer-necessary initializations.
108 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
109 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
110 use the unistd module.
111 * src/system.h: Likewise.
112 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
113 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
114 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
115 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
116 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
117 * src/system.h: Include inttypes.h unconditionally, now that we
118 use the inttypes module. Don't bother to include stdint.h, since
119 inttypes.h now does that for us.
120 (LOCALEDIR): Remove, now that we use the configmake module.
121 * src/getargs.c: Include configmake.h.
122 * src/main.c: Likewise.
123 * src/output.c: Likewise.
124 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
125 not from $abs_top_builddir, since config.h moved.
126
127
128 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
129 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
130
131 * src/parse-gram.y (symbol_declaration): Don't put statements
132 before declarations; it's not portable to C89.
133 * src/scan-code.l (handle_action_at): Likewise.
134
135 * src/scan-code.l: Always initialize braces_level; the old code
136 left it uninitialized and therefore had undefined behavior.
137
138 Don't attempt to redefine 'assert', since it runs afoul of
139 systems where standard headers (mistakenly) include <assert.h>.
140 Instead, define and use our own alternative, called 'aver'.
141 * src/reader.c: Don't include assert.h, since we no longer
142 use assert.
143 * src/scan-code.l: Likewise.
144 * src/system.h (assert): Remove, replacing with....
145 (aver): New function, taking a bool arg. All uses changed.
146 * src/tables.c (pack_vector): Ensure that aver arg is bool,
147 not merely an integer.
148
149 2006-09-15 Bob Rossi <bob@brasko.net>
150
151 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
152 * data/c.m4 (YYPUSH): New.
153 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
154 * src/getargs.c (push_parser): New var.
155 * src/getargs.h (push_parser): New declaration.
156 * src/output.c (prepare): Add macro insertion of `push_flag'.
157 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
158 (prologue_declaration): Parse %push-parser.
159 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
160 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
161 list of removed lines from the traces observed.
162 (AT_CHECK_CALC_LALR): Added push parser tests.
163
164 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
165
166 * NEWS: Version 2.3a.
167 * configure.ac (AC_INIT): Likewise.
168
169 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
170 "#define YYSTYPE int" that caused "make maintainer-check" to fail
171 due to header ordering dependencies. I don't know why the #define
172 was there.
173
174 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
175 runtime cost when YYDEBUG is not defined, and so that some tests
176 that used to fail now work. Problem and initial suggestion by
177 Paolo Bonzini.
178 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
179 * data/glr.cc (b4_parser_class_name):
180 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
181 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
182 (yydebug_) [YYDEBUG]: New member.
183 (yycdebug_): Now defined only if YYDEBUG.
184 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
185 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
186 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
187 if YYYDEBUG.
188 (debug_stream, set_debug_stream, debug_level, set_debug_level):
189 Define only if YYDEBUG.
190 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
191 set_debug_level.
192 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
193 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
194 AT_CHECK_CALC_GLR_CC that are working now.
195
196 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
197
198 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
199 We don't need them in glr.cc, and glr.c defines them.
200 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
201 assumes that defining it to anything is the same as defining
202 it to 1. Problem reported by Paolo Bonzini.
203
204 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
205
206 * data/c.m4 (b4_null, b4_case): Define.
207 * src/output.c (prepare_symbols): Use b4_null.
208 (user_actions_output): Use b4_case.
209
210 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
211
212 * data/glr.c (b4_shared_declarations): Put start-header first,
213 before any #includes that we generate, so that feature-test
214 macros work. Problem reported by Michael Deutschmann in
215 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
216 * data/lalr1.cc: Likewise.
217 * doc/bison.texinfo (Prologue): Document that feature-test macros
218 should be defined before any Bison declarations.
219 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
220 that depend on location.hh after, not before, Bison decls, since
221 we now include location.hh after the first user prologue.
222
223 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
224 Sander Brandenburg in
225 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
226 Also, fix minor white space and comment issues.
227 (Prologue): Mention that it's better to define feature-test macros
228 before Bison declarations. Problem reported by Michael Deutschmann.
229
230 * README-cvs: Fix typo: "&" should be "&&". Problem reported
231 by Jim Meyering.
232 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
233 This adjusts to recent gnulib changes.
234
235 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
236
237 Finish implementation of per-type %destructor/%printer. Discussed
238 starting at
239 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
240 and
241 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
242 * NEWS (2.3+): Add a description of this feature to the default
243 %destructor/%printer description.
244 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
245 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
246 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
247 list node contains a semantic type.
248 * src/symtab.c, src/symtab.h: Extend with a table that associates
249 semantic types with their %destructor's and %printer's.
250 (semantic_type_from_uniqstr, semantic_type_get,
251 semantic_type_destructor_set, semantic_type_printer_set): New functions
252 composing the public interface of that table.
253 (symbol_destructor_get, symbol_destructor_location_get,
254 symbol_printer_get, symbol_printer_location_get): If there's no
255 per-symbol %destructor/%printer, look up the per-type before trying
256 the default.
257 * tests/actions.at (Per-type %printer and %destructor): New test case.
258 * tests/input.at (Default %printer and %destructor redeclared):
259 Extend to check that multiple occurrences of %symbol-default in a
260 single %destructor/%printer declaration is an error.
261 (Per-type %printer and %destructor redeclared, Unused values with
262 per-type %destructor): New test cases.
263
264 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
265
266 Require default %destructor/%printer to be declared using
267 %symbol-default instead of an empty symbol list, and start working on
268 new per-type %destructor/%printer. Discussed at
269 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
270 * NEWS (2.3+): Add %symbol-default to example.
271 * bison.texinfo (Freeing Discarded Symbols): Likewise.
272 (Bison Symbols): Add entry for %symbol-default.
273 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
274 (generic_symlist, generic_symlist_item): New nonterminals for creating
275 a list in which each item is a symbol, semantic type, or
276 %symbol-default.
277 (grammar_declaration): Use generic_symlist in %destructor and %printer
278 declarations instead of symbols.1 or an empty list.
279 (symbol_declaration, precedence_declaration, symbols.1): Update actions
280 for changes to symbol_list.
281 * src/reader.c: Update for changes to symbol_list.
282 * src/scan-code.l: Likewise.
283 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
284 * src/symlist.c, src/symlist.h: Extend such that a list node may
285 represent a semantic type or a %symbol-default in addition to just an
286 ordinary symbol. Add switched functions for setting %destructor's and
287 %printer's.
288 * tests/actions.at, tests/input.at: Add %symbol-default to all default
289 %destructor/%printer declarations.
290
291 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
292
293 Whether the default %destructor/%printer applies to a particular symbol
294 isn't a question of whether the user *declares* that symbol (in %token,
295 for example). It's a question of whether the user by any means
296 *defines* the symbol at all (by simply using a char token, for
297 example). $end is defined by Bison whereas any other token with token
298 number 0 is defined by the user. The error token is always defined by
299 Bison regardless of whether the user declares it with %token, but we
300 may one day let the user define error as a nonterminal instead.
301 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
302 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
303 the meaning of "user-defined".
304 * tests/actions.at (Default %printer and %destructor for user-declared
305 end token): Rename to...
306 (Default %printer and %destructor for user-defined end token): ...
307 this.
308
309 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
310 computation of whether to apply the default, don't maintain a list of
311 every Bison-defined symbol. Instead, just check for a first character
312 of '$', which a user symbol cannot have, and check for the error token.
313
314 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
315
316 Don't apply the default %destructor or %printer to the error token,
317 $undefined, or $accept. This change fits the general rule that the
318 default %destructor and %printer are only for user-declared symbols,
319 and it solves several difficulties that are described in the new test
320 cases listed below.
321 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
322 * tests/actions.at (Default %printer and %destructor are not for error
323 or $undefined, Default %printer and %destructor are not for $accept):
324 New test cases.
325
326 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
327
328 Allow %start after the first rule.
329 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
330 when parsing the first rule.
331 (check_and_convert_grammar): Search for it here after all grammar
332 declarations have been parsed. Skip midrules, which have dummy LHS
333 nonterminals.
334 * src/symtab.c (symbol_is_dummy): New function.
335 * src/symtab.h (symbol_is_dummy): Declare it.
336 * tests/input.at (%start after first rule): New test.
337
338 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
339
340 Redo some of the previous commit: add back the ability to use
341 non-aliased/undeclared string literals since it might be useful to
342 those declaring %token-table.
343 * src/reader.c (check_and_convert_grammar): Undo changes in previous
344 commit: don't worry about complaints from symbols_pack.
345 * src/symtab.c (symbol_new, symbol_class_set,
346 symbol_check_alias_consistency): Undo changes in previous commit: count
347 each string literal as a new symbol and token, assign it a symbol
348 number, and don't complain about non-aliased string literals.
349 (symbols_pack): Since symbol_make_alias still does not decrement symbol
350 and token counts but does still set aliased tokens to the same number,
351 symbol_pack_processor now leaves empty slots in the symbols array.
352 Remove those slots.
353 * tests/regression.at (Undeclared string literal): Remove test case
354 added in previous commit since non-aliased string literals are allowed
355 again.
356 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
357 remove unnecessary string literal declarations.
358 * tests/sets.at (Firsts): Likewise.
359
360 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
361
362 Don't allow an undeclared string literal, but allow a string literal to
363 be used before its declaration.
364 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
365 symbols_pack complained.
366 * src/symtab.c (symbol_new): Don't count a string literal as a new
367 symbol.
368 (symbol_class_set): Don't count a string literal as a new token, and
369 don't assign it a symbol number since symbol_make_alias does that.
370 (symbol_make_alias): It's not necessary to decrement the symbol and
371 token counts anymore. Don't assume that an alias declaration occurs
372 before any uses of the identifier or string, and thus don't assert that
373 one of them has the highest symbol number so far.
374 (symbol_check_alias_consistency): Complain if there's a string literal
375 that wasn't declared as an alias.
376 (symbols_pack): Bail if symbol_check_alias_consistency failed since
377 symbol_pack asserts that every token has been assigned a symbol number
378 although undeclared string literals have not.
379 * tests/regression.at (String alias declared after use, Undeclared
380 string literal): New test cases.
381 (Characters Escapes, Web2c Actions): Declare string literals as
382 aliases.
383 * tests/sets.at (Firsts): Likewise.
384
385 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
386
387 In the grammar scanner, STRING_FINISH unclosed constructs and return
388 them to the parser in order to improve error messages.
389 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
390 SC_BRACED_CODE, SC_PROLOGUE): Implement.
391 * tests/input.at (Unclosed constructs): New test case.
392 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
393 seen.
394
395 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
396 unused global.
397
398 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
399
400 Handle string aliases for character tokens correctly.
401 * src/symtab.c (symbol_user_token_number_set): If the token has an
402 alias, check and set its alias's user token number instead of its own,
403 which is set to indicate the alias. Previously, every occurrence of
404 the character token in the grammar overwrote that alias indicator with
405 the character code.
406 * tests/input.at (String aliases for character tokens): New test.
407
408 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
409
410 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
411
412 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
413
414 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
415 to prevent failures when building on older platforms.
416 Check for autopoint failure.
417 Set XGETTEXT_OPTIONS to values that check for C format strings,
418 so that translators are warned about them (this also helps
419 prevent core dumps).
420
421 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
422 function, since it simplifies our code a bit.
423
424 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
425 rather than -W, so we don't get bogus warnings about sign comparisons.
426 Add -Wpointer-arith, since that warning is useful (it reports code
427 that does not conform to C89 and that some compilers reject).
428 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
429 since it's no longer needed.
430
431 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
432
433 Clean up scanners a bit.
434 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
435 definitions so gcc won't warn when obstack_for_string is unused.
436 * src/scan-code.l: config.h and system.h are already #include'd by
437 scan-code-c.c, so get rid of them here.
438 * src/scan-gram.l: Likewise.
439 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
440 definitions rather than duplicating the rest of it.
441 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
442
443 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
444
445 Suppress signed/unsigned comparison warnings for yycheck.
446 * data/c.m4 (b4_safest_int_type): New macro.
447 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
448 a signed int type, cast it to b4_safest_int_type first.
449 * data/yacc.c: Likewise.
450 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
451 also overwritten.
452
453 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
454
455 * doc/bison.texinfo: Fix some typos.
456
457 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
458
459 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
460 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
461
462 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
463 the latest gnulib does this a different way.
464 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
465 translation was patched, so stop omitting it.
466
467 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
468
469 Enable declaration of default %printer/%destructor. Make the parser
470 use these for all user-declared grammar symbols for which the user does
471 not declare a specific %printer/%destructor. Thus, the parser uses it
472 for token 0 if the user declares it but not if Bison generates it as
473 $end. Discussed starting at
474 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
475 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
476 and
477 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
478 * NEWS (2.3+): Mention.
479 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
480 declare a %destructor for a mid-rule's semantic value. It's just
481 impossible to declare one specific to it.
482 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
483 code. Describe default %destructor form.
484 * src/parse-gram.y (grammar_declaration): Parse default
485 %printer/%destructor declarations.
486 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
487 and symbol_destructor_location_get rather than accessing the destructor
488 and destructor_location members of struct symbol.
489 (symbol_printers_output): Likewise but for %printer's.
490 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
491 again.
492 * src/symtab.c (default_destructor, default_destructor_location,
493 default_printer, default_printer_location): New static global
494 variables to record the default %destructor and %printer.
495 (symbol_destructor_get, symbol_destructor_location_get,
496 symbol_printer_get, symbol_printer_location_get): New functions to
497 compute the appropriate %destructor and %printer for a symbol.
498 (default_destructor_set, default_printer_set): New functions to set the
499 default %destructor and %printer.
500 * src/symtab.h: Prototype all those new functions.
501 * tests/actions.at (Default %printer and %destructor): New test to
502 check that the right %printer and %destructor are called, that they're
503 not called for $end, and that $$ and @$ work correctly.
504 (Default %printer and %destructor for user-declared end token): New
505 test to check that the default %printer and %destructor are called for
506 a user-declared end token.
507 * tests/input.at (Default %printer and %destructor redeclared, Unused
508 values with default %destructor): New tests to check related grammar
509 warnings and errors.
510
511 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
512
513 Clean up handling of %destructor for the end token (token 0).
514 Discussed starting at
515 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
516 and
517 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
518
519 Make the skeletons consistent in how they pop the end token and invoke
520 its %destructor.
521 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
522 state, which has token number 0, since this would invoke the
523 %destructor for the end token.
524 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
525 until after shifting the end token, or else it won't be popped.
526 * data/yacc.c (yyparse): Likewise.
527
528 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
529 it's the end token. Upon termination, destroy an unshifted lookahead
530 even when it's the end token.
531 * data/lalr1.cc (yy::parser::parse): Likewise.
532 * data/yacc.c (yyparse): Likewise.
533
534 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
535 value warnings for the end token when the user gives the end token a
536 %destructor.
537
538 * tests/actions.at (Printers and Destructors): Test all the above.
539
540 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
541
542 Update to latest gnulib and gettext versions.
543 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
544 Add fopen-safer.
545 (gnulib_files): Add m4/warning.m4. Don't worry about files
546 overwritten by autopoint.
547 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
548 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
549 rejects them.
550 Don't use autoreconf; instead, invoke autopoint etc. by hand,
551 so that we can remove the intl files at a better time.
552 (intl_files_to_remove): Remove aclocal.m4, since it gets
553 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
554 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
555 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
556 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
557 Remove datarootdir hack; no longer needed.
558 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
559 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
560 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
561 strdup.h.
562 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
563 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
564
565 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
566
567 * bootstrap: Adjust to today's change to gnulib-tool by invoking
568 it with --assume-autoconf='latest-stable'.
569
570 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
571
572 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
573 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
574 YYSTYPE' and `{'.
575 * src/muscle_tab.h (muscle_grow): Replace the header comments with
576 those from muscle_tab.c since the old ones are misleading.
577
578 2006-07-13 Akim Demaille <akim@epita.fr>
579
580 Support %define "KEY" {VALUE}.
581 * src/scan-code.h, src/scan-code.l (translate_action)
582 (translate_rule_action, translate_symbol_action, translate_code):
583 Return char *, not const char *.
584 * src/parse-gram.y (declaration): Rename as...
585 (prologue_declaration): this.
586 (string_content): Remove this nonterminal, use STRING.
587 (braceless, content, content.opt): New nonterminal.
588 Use them.
589 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
590 as value.
591 * src/scan-gram.l (getargs.h): Don't include it.
592
593 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
594
595 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
596 rather than a for-loop that declares a local bool variable. This
597 should work around a compatibility problem with a Cray x1e C++
598 compiler reported by Hung Nguyen in
599 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
600 The for-loop was introduced in the 2004-11-17 change but I don't
601 know why it was needed.
602
603 2006-07-12 Akim Demaille <akim@epita.fr>
604
605 * data/c.m4: Comment changes.
606
607 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
608
609 * src/complain.c (error_message, ERROR_MESSAGE): New.
610 To factor...
611 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
612 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
613
614 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
615
616 * NEWS: Instead of %union, you can define and use your own union type
617 YYSTYPE if your grammar contains at least one <type> tag.
618 Your YYSTYPE need not be a macro; it can be a typedef.
619 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
620 (Union Decl, Decl Summary): Document this.
621 * data/glr.c (YYSTYPE): Implement this.
622 * data/glr.cc (YYSTYPE): Likewise.
623 * data/lalr1.cc (YYSTYPE): Likewise.
624 * data/yacc.c (YYSTYPE): Likewise.
625 * src/output.c (prepare): Output tag_seen_flag.
626 * src/parse-gram.y (declaration, grammar_declaration):
627 Use 'union_seen' rather than 'typed' to determine whether
628 %union has been seen, since grammars can now be typed without
629 %union.
630 (symbol_declaration, type.opt, symbol_def):
631 Keep track of whether a tag has been seen.
632 * src/reader.c (union_seen, tag_seen): New vars.
633 (typed): remove.
634 * src/reader.h (union_seen, tag_seen, typed): Likewise.
635 * src/scan-code.l (untyped_var_seen): New variable.
636 (handle_action_dollar): Adjust to above changes.
637 (handle_action_dollar, handle_action_at):
638 Improve overflow checking for outlandish numbers.
639 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
640 avoid new diagnostics generated by above changes.
641 * tests/regression.at (YYSTYPE typedef): Add test to check
642 for type tags without %union.
643
644 * src/symlist.c (symbol_list_length): Return int, not unsigned
645 int, since callers expect int. This may need to get revisited
646 once we have proper integer overflow checking.
647
648 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
649 object is now static.
650
651 * src/getargs.c (flags_argmatch): Return void, not int,
652 to pacify ./configure --enable-gcc-warnings.
653
654 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
655 since last_string is already defined to FLEX_PREFIX (last_string).
656
657 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
658
659 Implement --warnings/-W.
660 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
661 replaced by...
662 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
663 Adjust callers.
664 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
665 (warnings_args, warnings_types): New.
666 (getargs, short_options, long_options): Accept -W/--warnings.
667 Sort the options by alphabetical order, upper case letter right
668 before its lower case.
669
670 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
671
672 Change %merge result type clash warnings to errors. Discussed at
673 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
674 * src/reader.c (record_merge_function_type): Use complain_at.
675 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
676 declared later): Update test case results.
677
678 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
679
680 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
681 to be in alphabetical order.
682 (trace_args): Spelling fixes.
683
684 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
685
686 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
687 so they don't collide with user-defined macros.
688 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
689 this was never guaranteed, and now that we're using gnulib stdint,
690 which defines int_fast16_t to long int, the problem is exposed.
691
692 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
693
694 * data/c.m4 (b4_basename): Simplify a bit, since we don't
695 need the full POSIX semantics (and weren't implementing them
696 anyway).
697
698 Adjust to Autoconf 2.60 and today's gnulib.
699 * bootstrap (gnulib_modules): Add stdint.
700 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
701 no longer copies it.
702 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
703 since stdint needs the former and wcwidth (which is now required
704 by mbswidth) needs the latter.
705 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
706 work around a compatibility glitch between gettext 0.14.6 and
707 Autoconf 2.60.
708 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
709 Do not check for uintptr_t, since new stdint module does the right
710 thing.
711 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
712 Add stdint.h, stdint_.h, wcwidth.h.
713 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
714 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
715 stdint.m4, wchar_t.m4, wcwidth.m4.
716 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
717 usual order for ../lib/*.h files.
718 (file_name_split): Use last_component, not base_name, to adjust
719 to gnulib changes.
720 * src/parse-gram.h: Include <strverscmp.h> in the usual order
721 for ../lib/*.h files.
722 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
723 Define unconditionally, since we now assume the stdint module.
724 * src/scan-skel.l: Include <dirname.h>.
725 (BASE_QPUTS): Use last_component, not base_name.
726 * src/system.h: Include <unlocked-io.h> in the usual order
727 for ../lib/*.h files. Include <stdint.h> unconditionally,
728 since we now use the stdint module.
729 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
730 HAVE_UINTPTR_T, since we now use the stdint module.
731 (base_name): Remove decl, since files now include <dirname.h>
732 to get the decl.
733
734 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
735
736 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
737 New, default to 1.
738 * data/yacc.c, data/glr.c, data/location.cc: Use them.
739 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
740 default.
741 * tests/calc.at: Adjust.
742
743 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
744
745 * data/c.m4 (b4_basename): New.
746 (b4_syncline): Also output the location of its invocation (from
747 the skeleton).
748 (b4_user_action, b4_define_user_action, b4_user_actions)
749 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
750 (b4_user_stype): New.
751 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
752
753 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
754
755 In the grammar file, the first column is 1 not 0 on the first line as
756 on every other line.
757 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
758 * tests/input.at (Torturing the Scanner): Update output.
759
760 * src/scan-gram.l (scanner_cursor): Declare it static.
761
762 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
763
764 In warnings, say "previous declaration" rather than "first
765 declaration".
766 * src/symtab.c (redeclaration): Do that here.
767 * src/reader.c (record_merge_function_type): In the case of a result
768 type clash, report the previous declaration rather than the very first
769 one in the grammar file.
770 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
771 declared later): Add a third declaration to check this behavior.
772 * tests/input.at (Incompatible Aliases): Update output.
773
774 2006-06-27 Akim Demaille <akim@epita.fr>
775
776 * doc/Doxyfile.in: New.
777 * doc/Makefile.am: Use it.
778 * src/lalr.h, src/symtab.h: Initial doxygenation.
779
780 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
781
782 Don't miss %merge result type warnings just because the LHS types are
783 declared after the %merge. This continues the effort of the previous
784 patch.
785 * src/reader.c (get_merge_function): Don't set the merger type yet.
786 (record_merge_function_type): New function for setting the merger type
787 and checking for clashes.
788 (grammar_current_rule_merge_set): Set the location of the %merge for
789 the current rule.
790 (packgram): Invoke record_merge_function_type for each rule now that
791 all symbol type declarations have been parsed.
792 * src/reader.h (merger_list.type_declaration_location): New member
793 storing the location of the first %merge from which the type for this
794 merging function was derived.
795 * src/symlist.h (symbol_list.merger_declaration_location): New member
796 storing the location of a rule's %merge, if any.
797 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
798 declared later): New test to catch the error fixed by the above patch.
799
800 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
801
802 Get action warnings (grammar_rule_check) right even when symbol
803 declarations appear after the rules. Discussed at
804 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
805 and
806 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
807 Don't mistake the type of $$ in a midrule to be that of its parent
808 rule's $$.
809 * src/reader.c (grammar_current_rule_end): Don't invoke
810 grammar_rule_check yet since not all symbol declarations may have been
811 parsed yet.
812 (grammar_midrule_action): Likewise.
813 Don't record whether the midrule's $$ has been used yet since actions
814 haven't been translated yet.
815 Record the midrule's parent rule and its RHS index within the parent
816 rule.
817 (grammar_current_rule_action_append): Don't translate the action yet
818 since not all symbol declarations may have been parsed yet and, thus,
819 warnings about types for $$, $n, @$, and @n can't be reported yet.
820 (packgram): Translate the action and invoke grammar_rule_check now that
821 all symbol declarations have been parsed.
822 * src/scan-code.l (handle_action_dollar): Now that this is invoked
823 after parsing the entire grammar file, the symbol list here in the case
824 of a midrule is actually the midrule's empty RHS, so reference its
825 parent rule's RHS where necessary.
826 On the other hand, now that you can already know it's a midrule, you
827 aren't forced to think $$ has the same type as its parent rule's $$.
828 (handle_action_at): In the case of a midrule, reference the parent rule
829 where necessary.
830 * src/symlist.c (symbol_list_new): Initialize new midrule-related
831 members.
832 (symbol_list_length): Now that this is invoked after all rules have
833 been parsed, a NULL symbol (rather than a NULL symbol list node)
834 terminates a rule. symbol_list_print already does this correctly.
835 * src/symlist.h (symbol_list.midrule_parent_rule,
836 symbol_list.midrule_parent_rhs_index): New members so that midrules can
837 remember their relationships with their parents.
838 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
839 fixed by the above patch.
840 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
841 implementing...
842 (Unused values): ... this old test case and...
843 (Unused values before symbol declarations): ... this new test case.
844 This one is the same as `Unused values' except that all symbol
845 declarations appear after the rules in order to catch the rest of the
846 errors fixed by the above patch.
847
848 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
849
850 More cleanup.
851 * src/reader.c (current_rule): Declare it static since it's no longer
852 used outside this file.
853 (grammar_current_rule_action_append): Remove redundant arguments from
854 translate_rule_action invocation.
855 * src/reader.h (current_rule): Remove this unused extern.
856 * src/scan-code.h (translate_rule_action): Remove redundant arguments.

859 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
860
861 Clean up yesterday's patch.
862 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
863 to...
864 * src/reader.c (grammar_current_rule_action_append): ... here for
865 consistency with grammar_current_rule_symbol_append.
866 * tests/regression.at (Braced code in declaration in rules section):
867 Make yyerror and yylex static as usual.
868
869 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
870
871 Fix bug that mistakes braced code in a declaration in the rules section
872 to be a rule action. Mentioned at
873 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
874 * src/scan-gram.l: Move midrule action detection from the start of the
875 scanning of any braced code to...
876 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
877 action. For readability, use $2 and @2 rather than the equivalent
878 global variables.
879 * tests/regression.at (Braced code in declaration in rules section):
880 New test to catch the error fixed by the above patch.
881
882 Work on code readability some.
883 * src/scan-code.l (current_rule): Get rid of this misleading and
884 redundant declaration: it's actually extern'ed in reader.h.
885 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
886 translate_action): Add a rule argument and use it instead of the global
887 current_rule.
888 (translate_rule_action): This already receives current_rule through an
889 argument, so pass it on to translate_action instead of assigning
890 current_rule to current_rule.
891 (translate_symbol_action, translate_code): Pass rule = NULL to
892 translate_action.
893
894 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
895
896 Rename %before-definitions to %start-header and %after-definitions to
897 %end-header. Don't use these declarations to separate pre-prologue
898 blocks from post-prologue blocks. Add new order-independent
899 declarations %before-header and %after-header as alternatives to the
900 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
901 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
902 * NEWS (2.3+): Update for these changes.
903 * data/glr.c (b4_before_definitions): Update to...
904 (b4_start_header): ... this.
905 (b4_after_definitions): Update to...
906 (b4_end_header): ... this.
907 * data/glr.cc: Likewise.
908 * data/lalr1.cc: Likewise.
909 * data/yacc.c: Likewise.
910 * doc/bison.texinfo (The prologue): Update names, and replace remaining
911 prologue blocks with %*-header declarations.
912 (Calc++ Parser): Likewise.
913 (Bison Declaration Summary): Update names.
914 (Bison Symbols): Update description.
915 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
916 (PERCENT_END_HEADER): ... this.
917 (PERCENT_BEFORE_DEFINITIONS): Update to...
918 (PERCENT_START_HEADER): ... this.
919 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
920 (declaration): Update token names and m4 macro names.
921 When parsing %end-header and %start-header, invoke translate_code
922 before muscle_code_grow, and no longer set global booleans to remember
923 whether these declarations have been seen.
924 Parse new %after-header and %before-header.
925 * src/reader.c (before_definitions, after_definitions): Remove.
926 (prologue_augment): Accept a new bool argument to specify whether to
927 augment the pre-prologue or post-prologue.
928 * src/reader.h (before_definitions, after_definitions): Remove these
929 extern's.
930 (prologue_augment): Add new bool argument.

932 (PERCENT_END_HEADER): ... this.
933 (PERCENT_BEFORE_DEFINITIONS): Update to...
934 (PERCENT_START_HEADER): ... this.
935 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
936 * tests/actions.at (Printers and Destructors): Update names.
937
938 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
939
940 Add comparison operators for C++ location classes. Discussed at
941 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
942 * data/c++.m4 (b4_define_location_comparison): New boolean %define
943 declaration indicating whether filename_type has an operator==. If
944 filename_type is `std::string', it defaults to `1', `0' otherwise.
945 * data/location.cc: Iff b4_define_location_comparison is `1', add
946 operator== and operator!= for class position and for class location.
947
948 Some minor fixes.
949 * src/scan-action.l: Remove unused file.
950 * src/symtab.c (symbol_printer_set): Use printer_location not
951 destructor_location.
952 * src/symtab.h (struct symbol): Replace incorrect source comment for
953 printer members.
954 * tests/input.at (Incompatible Aliases): Update output with correct
955 printer location.
956
957 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
958
959 Don't put the pre-prologue in the header file. For the yacc.c code
960 file and the glr.c header and code files, move the pre-prologue before
961 the token definitions. Add new %before-definitions and
962 %after-definitions to declare code that will go in both the header file
963 and code file. Discussed at
964 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
965 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
966 and
967 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
968 * NEWS (2.3+): Describe these changes.
969 * data/glr.c (b4_pre_prologue): Move from within to before...
970 (b4_shared_declarations): ... this.
971 Add new b4_before_definitions before b4_token_enums.
972 Add new b4_after_definitions at the end.
973 * data/glr.cc (b4_pre_prologue): Replace with...
974 (b4_before_definitions): ... this in the header file.
975 (b4_after_definitions): New near the end of the header file.
976 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
977 code file right before including the header file.
978 (b4_before_definitions): New in the previous position of
979 b4_pre_prologue in the header file.
980 (b4_after_definitions): New near the end of the header file.
981 * data/yacc.c: Clean up some m4 quoting especially in the header file.
982 (b4_token_enums_defines): In the code file, move to right before
983 YYSTYPE for consistency with the header file.
984 (b4_before_definitions): New right before b4_token_enums_defines in
985 both the header and code file.
986 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
987 header and code file.
988 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
989 of prologues for %union dependencies.
990 (Bison Declaration Summary): In %defines description, mention the
991 effect of %before-definitions and %after-definitions on the header
992 file.
993 (Calc++ Parser): Forward declare driver in a %before-definitions rather
994 than in the pre-prologue so that make check succeeds.
995 (Bison Symbols): Add entries for %before-definitions and
996 %after-definitions.
997 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
998 %before-definitions.
999 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
1000 (declaration): Parse those declarations and append to
1001 b4_before_definitions and b4_after_definitions, respectively.
1002 * src/reader.c (before_definitions, after_definitions): New bools to
1003 track whether those declarations have been seen.
1004 (prologue_augment): Add to the post-prologue if %union,
1005 %before-definitions, or %after-definitions has been seen.
1006 * src/reader.h (before_definitions, after_definitions): New extern's.
1007 * src/scan-gram.l: Scan the new declarations.
1008 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
1009 prologue block in a %before-definitions or a %after-definitions based
1010 on whether the %union is declared.
1011 * tests/regression.at (Early token definitions with --yacc, Early token
1012 definitions without --yacc): Move tests for token definitions into the
1013 post-prologue since token names are no longer defined in the
1014 pre-prologue.
1015
1016 2006-06-20 Akim Demaille <akim@epita.fr>
1017
1018 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
1019 (symbol_get): Use it.
1020 * src/parse-gram.y: Use it.
1021
1022 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
1023
1024 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
1025 build succeeds when configured with --enable-gcc-warnings.
1026
1027 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1028
1029 * src/parse-gram.y (char_name): New function.
1030 (CHAR, STRING, string_content): For %printer, properly escape.
1031 (ID): Prefer fputs to fprintf.
1032 (id): Reindent to be consistent with other rules.
1033 Properly quote char.
1034
1035 The Translation Project changed its way of publishing translations
1036 to maintainers. I haven't received any responses to my request
1037 for supporting the old way, or for documenting the new way. I
1038 have modified 'bootstrap' to use screen scraping
1039 (in this case, HTML scraping). This is unreliable and inelegant,
1040 but I don't see any better way. Yuck.
1041 * bootstrap (TP_URL, WGET_COMMAND): New vars.
1042 (get_translations): New function, which uses HTML scraping to
1043 deduce locations of latest translations.
1044 Use this function to grab both bison and bison-runtime .po files.
1045 Don't bother priming the pump for the runtime-po domain any more,
1046 as it's now translated better than bison is.
1047
1048 2006-06-19 Akim Demaille <akim@epita.fr>
1049
1050 * src/scan-gram.l: No longer "parse" things after `%union' until
1051 `{'. Rather, return a single "%union" token.
1052 No longer make symbols: return strings, and leave the conversion
1053 to symbols to the parser.
1054 (SC_PRE_CODE, token_type): Remove.
1055 * src/parse-gram.y (%union): New field `character'.
1056 Sort tokens.
1057 (CHAR): New token.
1058 (ID, ID_COLON): Now that the scanner no longer makes them
1059 identifiers, adjust all uses to invoke symbol_get.
1060 (id_colon): New, wraps the conversion from string to symbol.
1061 (%union): Accept a possible union_name.
1062 (symbol): Now can be a char.
1063 * data/c.m4 (b4_union_name): Leave a default value.
1064 * data/glr.c, data/yacc.c: Use it.
1065
1066 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
1067
1068 For associating token numbers with token names for "yacc.c", don't use
1069 #define statements unless `--yacc' is specified; always use enum
1070 yytokentype. Most important discussions start at:
1071 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
1072 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
1073 and
1074 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
1075 * NEWS (2.3+): Mention.
1076 * data/c.m4 (b4_yacc_if): New.
1077 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
1078 token #define's.
1079 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
1080 on token name definitions.
1081 * src/getargs.c (usage): Capitalize `Yacc' in English.
1082 * src/output.c (prepare): Define b4_yacc_flag.
1083 * tests/regression.at (Early token definitions): Test that tokens names
1084 are defined before the pre-prologue not just before the post-prologue.
1085 Remove this test case and copy to...
1086 (Early token definitions with --yacc): ... this to test #define's.
1087 (Early token definitions without --yacc): ... and this to test enums.
1088
1089 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
1090
1091 * NEWS: Reword the post-2.3 change to not be so optimistic about
1092 removing the old "look-ahead" spelling.
1093 Update previous look-ahead/lookahead change reports.
1094 * REFERENCES: look-ahead -> lookahead (since that's
1095 what he actually wrote).
1096 * doc/refcard.tex: look ahead -> lookahead,
1097 look-ahead -> lookahead
1098
1099 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
1100
1101 For consistency, use `lookahead' instead of `look-ahead' or
1102 `look_ahead'. Discussed starting at
1103 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
1104 and then at
1105 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

1171
1172 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
1173
1174 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
1175
1176 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1177
1178 * TODO: Add request from Nelson H. F. Beebe to be able to install
1179 Bison without installing the yacc script.
1180
1181 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
1182
1183 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
1184 and yytext if they're already #define'd.
1185 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
1186 * src/scan-code-c.c: ... here.
1187 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
1188 <config.h>.
1189
1190 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
1191
1192 Get Bison to build again when configured with --enable-gcc-warnings.
1193 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
1194 missing #include's.
1195 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
1196 loc argument as it shadows a global.
1197 * src/scan-gram.l: Remove stray comma that prevents boundary_set
1198 invocation.

1213
1214 2006-06-06 Akim Demaille <akim@epita.fr>
1215
1216 Extract the parsing of user actions from the grammar scanner.
1217 As a consequence, the relation between the grammar scanner and
1218 parser is much simpler. We can also split "composite tokens" back
1219 into simple tokens.
1220 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
1221 * src/scan-gram.l (add_column_width, adjust_location): Move to and
1222 rename as...
1223 * src/location.h, src/location.c (add_column_width)
1224 (location_compute): these.

1233 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
1234 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
1235 which is now, again, a separate token.
1236 Adjust all dependencies.
1237 Whereever actions with $ and @ are used, use translate_code.
1238 (action): Remove this nonterminal which is now useless.
1239 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
1240 (grammar_current_rule_action_append): Use translate_code.
1241 (packgram): Bound check ruleno, itemno, and rule_length.
1242 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
1243 (last_string, last_braced_code_loc, max_left_semantic_context)
1244 (scanner_initialize, scanner_free, scanner_last_string_free)
1245 (gram_out, gram_lineno, YY_DECL_): Move to...
1246 * src/scan-gram.h: this new file.
1247 (YY_DECL): Rename as...
1248 (GRAM_DECL): this.
1249 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
1250 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
1251 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
1252 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
1253 Move these declarations, and...
1254 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
1255 these to...
1256 * src/flex-scanner.h: this new file.
1257 * src/scan-gram.l (rule_length, rule_length_overflow)
1258 (increment_rule_length): Remove.
1259 (last_braced_code_loc): Rename as...
1260 (gram_last_braced_code_loc): this.
1261 Adjust to the changes of the parser.
1262 Move all the handling of $ and @ into...
1263 * src/scan-code.l: here.
1264 * src/scan-gram.l (handle_dollar, handle_at): Remove.
1265 (handle_action_dollar, handle_action_at): Move to...
1266 * src/scan-code.l: here.
1267 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
1268 scan-code.h, scan-code-c.c, scan-gram.h.
1269 (EXTRA_bison_SOURCES): Add scan-code.l.
1270 (BUILT_SOURCES): Add scan-code.c.
1271 (yacc): Be robust to white spaces.
1272
1273 * tests/conflicts.at, tests/input.at, tests/reduce.at,
1274 * tests/regression.at: Adjust the column numbers.
1275 * tests/regression.at: Adjust the error message.
1276
1277 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
1278
1279 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
1280 Use Akim's wording from
1281 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.

1285 Between Bison releases, manually append `+' to the previous Bison
1286 release number, and use that as a signal to automatically print the
1287 ChangeLog's CVS Id keyword from --version. Discussed starting at
1288 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
1289 * ChangeLog: Add Id header.
1290 * configure.ac (AC_INIT): Append `+' to `2.3'.
1291 * src/.cvsignore: Add revision.c.
1292 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
1293 (BUILT_SOURCES): Add revision.c.
1294 (revision.c): New target rule. This file defines a new global variable
1295 named revision. It initializes it with either the Id from ChangeLog
1296 or, if VERSION doesn't contain `+', with the empty string.
1297 * src/getargs.c (version): Print the value of revision.
1298 * src/revision.h: Extern revision.

1305 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1306
1307 * data/glr.c (YYRECOVERING): Define to be a function-like macro
1308 with no arguments, not as an object-like macro. This is for
1309 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
1310 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
1311 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
1312 Document this.
1313
1314 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
1315
1316 * src/getargs.c (usage): Back out yesterday's modification of the
1317 --help output so that we don't have to wait for translation before
1318 releasing 2.3.
1319
1320 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1321
1322 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
1323 Problem reported by Akim Demaille.
1324
1325 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
1326
1327 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
1328
1329 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1330
1331 * data/yacc.c (yy_reduce_print): Omit trailing white space in
1332 generated source code. Problem reported by Frans Englich in
1333 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
1334
1335 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
1336
1337 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
1338 shell, not within 'make', so that 'make' by an ordinary builder
1339 (using GNU make) does not worry about configuring gzip. This also
1340 works around a bug reported independently by Keith Thompson and by
1341 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
1342 stderr rather than stdout, messing up the build logs.
1343
1344 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
1345
1346 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
1347 to make sure that YYID will never be unused. This fixes a 'make
1348 maintainer-check' failure caused by the recent changes to the 'Trivial
1349 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
1350 not used.
1351 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
1352
1353 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
1354
1355 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
1356 state before an empty RHS is always resolved here. Only the location
1357 of that state is guaranteed to be resolved, and that's enough. This
1358 fixes the remaining bug reported by Derek M. Jones in
1359 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
1360 * tests/glr-regression.at (Uninitialized location when reporting
1361 ambiguity): Test the above case.
1362 Also, the embedded comments in this test case claim it checks the case
1363 of an empty RHS that has inherited the initial location. However, the
1364 corresponding LHS was already resolved, so yyresolveLocations didn't
1365 actually have reason to modify it. Fix this by forcing
1366 nondeterministic operation at the beginning of the parse.
1367
1368 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1369
1370 * data/c.m4 (b4_yy_symbol_print_generate):
1371 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
1372 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
1373 of the bugs reported today by Derek M Jones in
1374 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
1375 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
1376 defined to be a type name without parens or brackets.
1377 (Location Type): Similarly for YYLTYPE.
1378 * tests/regression.at (Trivial grammars): Put in a test for this
1379 bug that will be caught by 'make maintainer-check' (though not,
1380 alas, by 'make check' unless your compiler is picky).
1381
1382 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1383
1384 * NEWS: Version 2.2.
1385 * configure.ac (AC_INIT): Likewise.
1386
1387 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
1388
1389 * data/glr.c (yyreportTree): Make room in yystates for the state
1390 preceding the RHS. This fixes the segmentation fault reported by Derek
1391 M. Jones in
1392 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
1393 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
1394 to the user. Reported for yyreportTree by Derek M. Jones later in the
1395 same thread.
1396 * THANKS: Add Derek M. Jones.
1397 Update my email address.
1398 Fix typo in Steve Murphy's name.
1399
1400 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1401
1402 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
1403 checking against YYLAST that caused the parser to miss a potential
1404 alternative in its diagnostic.
1405 Problem reported by Maria Jose Moron Fernandez in
1406 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
1407 * data/lalr1.cc (yysyntax_error_): Likewise.
1408 * data/yacc.c (yysyntax_error): Likewise.
1409 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
1410 tokens, in case we run into an older C compiler.
1411 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
1412 Use them to check for the off-by-one error fixed above.
1413
1414 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
1415 YYSIZE_T, not size_t.
1416 * tests/regression.at (Trivial grammars): New test, to catch
1417 the error fixed by the above patch.
1418
1419 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1420
1421 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
1422 scheme.
1423 Reported by Steve Murphy.
1424
1425 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1426
1427 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
1428 * data/glr.cc: b4_location_flag is now b4_locations_flag.
1429
1430 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1431
1432 Implement --trace=m4.
1433 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
1434 * src/output.c (output_skeleton): When set, pass -dV to m4.
1435
1436 Factor the handling of flags in m4.
1437 * src/output.c (prepare): Rename the muscle names debug, defines,
1438 error_verbose to debug_flag, defines_flag, error_verbose_flag.
1439 * data/c.m4: Adjust.
1440 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
1441 Use b4_define_flag_if to define other b4_FLAG_if macros.
1442 (b4_location_if): As a consequence, rename as...
1443 (b4_locations_if): this, for consistency.
1444 Adjust all the skeletons.
1445
1446 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1447
1448 * etc/bench.pm: Shorten bench names.

1450 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1451
1452 * src/output.h, src/output.c (error_verbose): Move to...
1453 * src/getargs.h, src/getargs.c: here.
1454 Sort the flags.
1455 Adjust dependencies.
1456
1457 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1458
1459 * data/c.m4 (b4_copyright): Put the special exception for Bison
1460 skeletons here, so we don't have to put it in each skeleton. All
1461 uses changed. Suggested by Akim Demaille. Also, wrap the
1462 copyright notice, in case it is longer than 80 columns. Replace
1463 comma by newline after title.
1464
1465 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1466
1467 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
1468 incompatibility, not a bug. Mention that it wasn't fixed as of
1469 flex 2.5.33.
1470
1471 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
1472
1473 * examples/extexi: Enforce the precedence of concatenation over
1474 >>.
1475 Reported by Tommy Nordgren.
1476
1477 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
1478
1479 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
1480 with the member "token".
1481 Reported by Martin Nylin.
1482
1483 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
1484
1485 * data/glr.c: Switch to Bison 2.2 special-exception language in
1486 the copyright notice. Use more-regular format for titles and
1487 copyright notices.
1488 * data/glr.cc: Likewise.
1489 * data/location.cc: Likewise.
1490 * data/yacc.cc: Likewise.
1491 * doc/bison.texinfo (Conditions): Document this.
1492 * NEWS: likewise. Upgrade version to 2.2.
1493
1494 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
1495
1496 * data/glr.cc: Remove dead code.
1497
1498 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1499
1500 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
1501 that variable and the line breaks the bootstrap. Problem reported
1502 by Juan M. Guerrero.
1503
1504 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

1514 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
1515 rule.
1516 Reported by Mickael Labau.

1524 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
1525
1526 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
1527 and didn't really work.
1528 For the index, use @ifnotinfo, not @iftex.
1529 Minor cleanups of spacing and terminology.
1530
1531 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
1532
1533 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
1534 of AT_NAME_PREFIX when %name-prefix is not used.
1535
1536 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
1537
1538 Apply --prefix to C++ skeletons too: they change the namespace.
1539 The test suite already exercize these cases.
1540 * data/c++.m4 (b4_namespace): New.
1541 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
1542 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
1543 * data/yacc.c, data/glr.c: Remove a useless `[]'.
1544 * doc/bison.texinfo: Document it.
1545 (Option Cross Key): Use @multitable in all formats. It looks
1546 nicer, even in TeX outputs.
1547 (Rules): Use the same code whatever the output type is.
1548 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
1549 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
1550 * tests/calc.at: Use it, instead of hard coding `yy'.

1569 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
1570
1571 Fix two nits reported by twlevo, plus one more that I discovered.
1572
1573 * src/assoc.h (assoc_to_string): Give a name to the arg, as
1574 this is the usual Bison style.
1575 * src/location.h (location_print): Likewise.
1576
1577 * src/reader.h (token_name): Likewise.
1578
1579 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
1580
1581 Fix some nits reported by twlevo.
1582 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
1583 and "POSIX". Use more-modern syntax for URLs. Mention C++
1584 and ask for Java. Don't hardwire OS version numbers. Add
1585 copyright notice.
1586 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
1587 * src/conflicts.c (solved_conflicts_obstack): Now static.
1588
1589 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
1590
1591 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
1592 page. Say "you can use it" not "you may use it" as on the web page;
1593 we're describing capabilities not granting permission.
1594
1595 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
1596
1597 * data/glr.c (yyresolveLocations): Rename local variables to avoid
1598 shadowing warnings. Use usual patter for iterating through RHS.
1599 * tests/glr-regression.at
1600 (Uninitialized location when reporting ambiguity):
1601 Modify yylex so that it uses its argument, rather than trying
1602 to rely on ARGSUSED (which doesn't work for gcc with warnings).
1603 const char -> char const.
1604
1605 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
1606 Don't use tabs inside commands; it messes up 'ps'.
1607 Problem reported by twlevo.
1608
1609 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
1610
1611 * tests/glr-regression.at (Uninitialized location when reporting
1612 ambiguity): New test case.
1613 * data/glr.c (yyresolveLocations): New function, which uses
1614 YYLLOC_DEFAULT.
1615 (yyresolveValue): Invoke yyresolveLocations before reporting an
1616 ambiguity.
1617 * doc/bison.texinfo (Default Action for Locations): Note
1618 YYLLOC_DEFAULT's usage for ambiguity locations.
1619 (GLR Semantic Actions): Cross-reference those notes.
1620
1621 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
1622
1623 * tests/glr-regression.at (Leaked semantic values when reporting
1624 ambiguity): Remove unnecessary union and type declarations.
1625 (Leaked lookahead after nondeterministic parse syntax error): New test
1626 case.
1627 * data/glr.c (yyparse): Check for zero stacks remaining before
1628 attempting to shift the lookahead so that you don't lose it.
1629
1630 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
1631
1632 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
1633 * tests/glr-regression.at (Leaked semantic values when reporting
1634 ambiguity): New test case.
1635 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
1636 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
1637 now unnecessary yystackp parameter.
1638 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
1639 destructors can be called.
1640
1641 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
1642 in existing testcases.
1643
1644 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
1645
1646 Don't leak semantic values for parent RHS when a user action cuts the
1647 parser, and clean up related code a bit.
1648 * tests/glr-regression.at (Leaked merged semantic value if user action
1649 cuts parse): Rename to...
1650 (Leaked semantic values if user action cuts parse): ... this. Add check
1651 for leaked parent RHS values.
1652 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
1653 between an unresolved state (non-empty chain of semantic options) and
1654 an incomplete one (signaled by an empty chain).
1655 (yyresolveStates): Document the interface. Move all manipulation of a
1656 successfully or unsuccessfully resolved yyGLRState to...
1657 (yyresolveValue): ... here so that yyresolveValue always leaves a
1658 yyGLRState with consistent data and thus is easier to understand.
1659 Remove the yyvalp and yylocp parameters since they are always just
1660 taken from the yys parameter. When reporting a discarded merged value
1661 in debugging output, note that it is incompletely merged. Document the
1662 interface.
1663 (yyresolveAction): If resolving any of the RHS states fails, destroy
1664 them all rather than leaking them. Thus, as long as user actions are
1665 written to clean up the RHS correctly, yyresolveAction always cleans up
1666 the RHS of a semantic option. Document the interface.

1697 * configure.ac (AC_INIT): Bump version number.
1698
1699 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
1700
1701 * NEWS: Version 2.1a.
1702 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
1703 since C99 requires this.
1704
1705 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
1706
1707 * m4/c-working.m4: New file.
1708 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
1709
1710 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
1711
1712 * Makefile.maint: Merge from coreutils.

1716 More portability fixes for problems summarized by Nelson H. F. Beebe.
1717
1718 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
1719 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
1720 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
1721 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
1722 messes up because C++ code is compiled in 32-bit mode but linked
1723 in 64-bit mode.

1725 2006-02-08 Paul Eggert <eggert@cs.ucla.edu>

1727 More portability fixes for problems summarized by Nelson H. F. Beebe.
1728
1729 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
1730 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
1731
1732 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
1733 nodist_PROGRAMS, since we don't need to actually compile the
1734 example if we're just doing a plain 'make'. This avoids bothering
1735 the installer unnecessarily about problems due to weird C++
1736 compilers.
1737
1738 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
1739
1740 More portability fixes for problems summarized by Nelson H. F. Beebe.
1741
1742 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
1743 than #include "...", and compile with -I'.'. The old method was
1744 not portable, according to Posix and the C standard, and it does
1745 not work with Sun C 5.7, where previous #line directives affect
1746 the working directory used in later #include "..." directives.

1753
1754 More portability fixes for problems summarized by Nelson H. F. Beebe.
1755
1756 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
1757 '#include <map>' works and that you can apply ++ to iterators.
1758
1759 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
1760
1761 Work around portability problems summarized by Nelson H. F. Beebe in
1762 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
1763
1764 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
1765 that '#include <string>' works.
1766
1767 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
1768 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
1769 "warning: sorry: semantics of inline function static data `const
1770 unsigned char translate_table[262]' are wrong (you'll wind up with
1771 multiple copies)".
1772
1773 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
1774 or, xor to not_, and_, or_, and xor_, respectively. This works
1775 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
1776 random system header somewhere that includes the equivalent of
1777 <iso646.h>.
1778
1779 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
1780 -E" works; it apparently doesn't work with PathScale EKO Compiler
1781 Suite Version 2.0.
1782
1783 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
1784
1785 During deterministic GLR operation, user actions should be able to
1786 influence the parse by changing yychar. To make this easier to fix and
1787 to make glr.c easier to evolve in general, don't maintain yytoken in
1788 parallel with yychar; just compute yytoken when needed.
1789 * tests/glr-regression.at (Incorrect lookahead during deterministic
1790 GLR): Check that setting yychar in a user action has the intended
1791 effect.
1792 * data/glr.c (yyGLRStack): Remove yytokenp member.
1793 (yyclearin): Don't set *yytokenp.
1794 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
1795 yychar rather than *yytokenp to determine the current lookahead.
1796 Compute yytoken locally when needed.
1797 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
1798 point to.
1799
1800 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
1801 after `--report' documentation.
1802
1803 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
1804
1805 * src/parse-gram.y (grammar_declaration): Location of printer
1806 symbol is @1, not list->location. Bug reported by twlevo.
1807 * tests/input.at (Incompatible Aliases): Adjust to above change.
1808
1809 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
1810
1811 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
1812 all the test at once. This makes the output easier to read in the
1813 normal case.
1814
1815 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
1816 got from <http://bro-ids.org/download.html>. The bug is that
1817 when two actions appeared in succession, the second one was
1818 scanned before the first one was added to the grammar rule
1819 as a midrule action. Bison then output the incorrect warning
1820 "parse.y:905.17-906.36: warning: unused value: $3".
1821 * src/parse-gram.y (BRACED_CODE, action): These are no longer
1822 associated with a value.
1823 (rhs): Don't invoke grammar_current_rule_action_append.
1824 (action): Invoke it here instead.
1825 * src/reader.c (grammar_midrule_action): Now extern.
1826 (grammar_current_rule_action_append): Don't invoke
1827 grammar_midrule_action; that is now the scanner's job.
1828 * src/reader.h (last_string, last_braced_code_loc):
1829 (grammar_midrule_action): New decls.
1830 * src/scan-gram.l (last_string): Now extern, sigh.
1831 (last_braced_code_loc): New extern variable.
1832 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
1833 rule already has an action.
1834 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
1835 * tests/input.at (AT_CHECK_UNUSED_VALUES):
1836 Add some tests to check that the above changes fixed the bug.
1837
1838 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
1839
1840 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
1841 All used changed. Check whether the symbol has a destructor,
1842 not whether it is typed.
1843 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
1844 that the values are still reported as unused. All line numbers
1845 adjusted.
1846
1847 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
1848
1849 Work around a bug in bro 0.8, which underparenthesizes its
1850 definition of YYLLOC_DEFAULT.
1851 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
1852 their arguments.
1853 * data/lalr1.cc: Likewise.
1854 * data/yacc.cc: Likewise.
1855
1856 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
1857
1858 Work around a bug in Pike 7.0, and give the Pike folks a
1859 better way to override the usual int widths.
1860 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
1861 user can override the types.
1862 (short): #undef, to work around a bug in Pike 7.0.
1863 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
1864 (union yyalloc.yyss): Use yytype_int16 rather than short.
1865 All uses changed.
1866 (yysigned_char): Remove.
1867 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
1868 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
1869 * tests/regression.at (Web2c Actions): Adjust to above changes.
1870
1871 * src/reader.c (check_and_convert_grammar): New function.
1872 (reader): Close the input file even if something went wrong during
1873 parsing. Minor file descriptor leak reported by twlevo.
1874
1875 * src/assoc.c (assoc_to_string): Use a default: abort (); case
1876 to pacify gcc -Wswitch-default.
1877 * src/scan-gram.l (adjust_location): Use a default: break; case
1878 to pacify gcc -Wswitch-default.
1879 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
1880 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
1881 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
1882 Move these decls to scan-skel.l, since they don't need to be
1883 visible elsewhere.
1884 * src/scan-skel.l: Accept the above decls.
1885 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
1886 is used.
1887
1888 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
1889
1890 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
1891 since we don't want to insist on a version number at the start
1892 of the changelog every time.
1893 * Makefile.maint: Sync from coreutils a bit better.
1894 (sc_trailing_blank): Renamed from sc_trailing_space.
1895 All uses changed.
1896 (sc_no_if_have_config_h, sc_require_config_h):
1897 (sc_prohibit_assert_without_use): New rules.

1900 (sc_system_h_headers): Prefix with @.
1901 (sc_useless_cpp_parens, m4-check): Output line numbers.
1902 (changelog-check): Allow version only in head.
1903 * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
1904 satisfy new Makefile.maint rule.
1905 * data/glr.c: Likewise.
1906 * data/glr.cc: Likewise.

1942 that for us.

1944 * .x-sc_unmarked_diagnostics: New file.
1945
1946 2006-01-20 Paul Eggert <eggert@cs.ucla.edu>
1947
1948 Be a bit more systematic about using 'abort'.
1949 * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
1950 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
1951 Put 'default: abort ();' before some other case, to satisfy older
1952 pedantic compilers.
1953 * lib/bitset_stats.c (bitset_stats_init): Likewise.
1954 * lib/ebitset.c (ebitset_elt_find, ebitset_op3_cmp): Likewise.
1955 * lib/lbitset.c (lbitset_elt_find, lbitset_op3_cmp): Likewise.

1959 (get_arrow_mode_str, get_crossing_type_str, get_view_str):
1960 (get_linestyle_str, get_arrowstyle_str): Likewise.
1961 * src/conflicts.c (resolve_sr_conflict):
1962 Use a default case rather than one for the one remaining enum
1963 value, to catch invalid enum values as well.
1964 * src/lalr.c (set_goto_map, map_goto):
1965 Prefer "assert (FOO);" to "if (!FOO) abort ();".
1966 * src/nullable.c (nullable_compute, token_definitions_output):

1978
1979 * doc/bison.texinfo (Prologue, Rules, Actions, Union Decl, Action Decl):
1980 (Destructor Decl, Parser Function, Pure Calling):
1981 Describe rules for braces inside C code more carefully.
1982
1983 2006-01-19 Paul Eggert <eggert@cs.ucla.edu>
1984
1985 Fix some porting glitches found by Nelson H. F. Beebe.
1986 * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
1987 compilers that don't understand that abort () does not return.
1988 * src/state.c (transitions_to): Likewise.
1989 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
1990 that '#include <cstdlib>' works.
1991 * src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
1992 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
1993 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
1994 for the benefit of some pre-C99 compilers.
1995
1996 * bootstrap: Undo changes to gnulib files that autoreconf made.
1997
1998 Minor fixups to get 'make maintainer-check' to work.
1999 * configure.ac: Don't use -Wnested-externs, as it's incompatible
2000 with the new verify.h implementation.
2001 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
2002 * data/glr.c (YYUSE): Depend on __GNUC__ as well.
2003 * data/yacc.c (YYUSE): Likewise.

2005 * lib/subpipe.c (end_of_output_subpipe): The args are unused.
2006 * src/parse-gram.y (declaration): Don't pass a string constant
2007 to a function that expects char *, since GCC might complain
2008 about the constant value.
2009 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
2010 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
2011 before #defining them.
2012 * tests/glr-regression.at
2013 (Incorrectly initialized location for empty right-hand side in GLR):
2014 In yyerror, use the msg arg.
2015 (Corrupted semantic options if user action cuts parse):
2016 (Incorrect lookahead during deterministic GLR):
2017 (Incorrect lookahead during nondeterministic GLR):
2018 Don't name a local var 'index'; it shadows string.h's 'index'.
2019
2020 2006-01-19 Akim Demaille <akim@epita.fr>
2021
2022 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
2023 location, not just parts of it.
2024
2025 2006-01-18 Paul Eggert <eggert@cs.ucla.edu>
2026
2027 * NEWS: Document the fact that multiple %unions are now allowed.
2028 * doc/bison.texinfo (Union Decl): Likewise.
2029 * TODO: This feature is now implemented, so remove it from
2030 the wishlist.
2031
2032 * Makefile.maint: Merge with coreutils Makefile.maint.
2033 (CVS_LIST): Use build-aux version if available.
2034 (VERSION_REGEXP): New macro.
2035 (syntax-check-rules): Add sc_no_if_have_config_h,
2036 sc_prohibit_assert_without_use, sc_require_config_h,
2037 sc_useless_cpp_parens.
2038 (sc_obsolete_symbols): Check for O_NDELAY.
2039 (sc_dd_max_sym_length): Track coreutils.
2040 (sc_unmarked_diagnostics): Look in all files, not just *.c.
2041 (sc_useless_cpp_parens): New rule.
2042 (news-date-check): Look for version or today's date.
2043 (changelog-check): Don't require version number near head.
2044 (copyright-check): Use current year instead of hardwiring 2005.
2045 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
2046 (announcement): Add --gpg-key-ID.
2047
2048 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
2049 with "file system".
2050
2051 Avoid undefined behavior that addressed just before the start of an
2052 array. Problem reported by twlevo.
2053 * src/reader.c (packgram): Prepend a new sentinel before ritem.
2054 * src/lalr.c (build_relations): Rely on new sentinel.
2055 * src/gram.c (gram_free): Adjust to new sentinel.
2056
2057 2006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
2058
2059 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
2060 yylookaheadNeeds. All uses updated.
2061 (yysplitStack): Rename local yynewLookaheadStatuses to
2062 yynewLookaheadNeeds.
2063 * data/glr-regression.at (Incorrect lookahead during nondeterministic
2064 GLR): In comments, change `lookahead status' to `lookahead need'.
2065
2066 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2067
2068 * data/glr.c (yysplitStack): A little stylistic rewrite.
2069
2070 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2071
2072 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
2073
2074 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
2075
2076 * doc/bison.texinfo: Fix some typos.
2077 (GLR Semantic Actions): New subsection discussing special
2078 considerations because GLR semantic actions might be deferred.
2079 (Actions): Mention look-ahead usage of yylval.
2080 (Actions and Locations): Mention look-ahead usage of yylloc.
2081 (Special Features for Use in Actions): Add YYEOF entry and mention it
2082 in the yychar entry.
2083 In the yychar entry, remove mention of the local yychar case (pure
2084 parser) since this is irrelevant information when writing semantic
2085 actions and since it's already discussed in `Bison Symbols' where
2086 yychar is otherwise described as an external variable.
2087 In the yychar entry, don't call it the `current' look-ahead since it
2088 isn't when semantic actions are deferred.
2089 In the yychar and yyclearin entries, add note about deferred semantic
2090 actions.
2091 Add yylloc and yylval entries discussing look-ahead usage.
2092 (Look-Ahead Tokens): When discussing yychar, don't call it the
2093 `current' look-ahead, and do mention yylval and yylloc.
2094 (Error Recovery): Cross-reference `Action Features' when mentioning
2095 yyclearin.
2096 (Bison Symbols): In the yychar entry, don't call it the `current'
2097 look-ahead.
2098 In the yylloc and yylval entries, mention look-ahead usage.
2099
2100 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2101
2102 * tests/glr-regression.at: Update copyright year to 2006.
2103
2104 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2105
2106 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
2107 use during nondeterministic operation to track which stacks have
2108 actually needed the current lookahead.
2109 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
2110 Allocate, deallocate, resize, and otherwise shuffle space for
2111 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
2112 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
2113 appropriately during nondeterministic operation.
2114 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
2115 members to store the current lookahead to be used by the deferred
2116 user action.
2117 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
2118 from which the RHS is taken. Set the lookahead members of the new
2119 yySemanticOption according to the lookahead status for stack yyk.
2120 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
2121 yyaddDeferredAction.
2122 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
2123 members of yySemanticOption before invoking yyuserAction, and then set
2124 them back to their current values afterward.
2125 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
2126 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
2127 * tests/glr-regression.at: Remove `.' from the ends of recent test case
2128 titles for consistency.
2129 (Leaked merged semantic value if user action cuts parse): In order to
2130 suppress lint warnings, use arguments in merge function, and assign
2131 char value < 128 in main.
2132 (Incorrect lookahead during deterministic GLR): New test case.
2133 (Incorrect lookahead during nondeterministic GLR): New test case.
2134
2135 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2136
2137 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
2138 !yyvaluep as signal that no semantic value is available to print.
2139 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
2140 to print a semantic value.
2141
2142 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2143
2144 * tests/glr-regression.at: For consistency with my newer test cases,
2145 don't thank myself.
2146
2147 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2148
2149 * data/glr.c (yyresolveValue): When merging semantic options, if at
2150 least one user action succeeds but a later one cuts the parse, then
2151 destroy the semantic value before returning rather than leaking it.
2152 (yyresolveStates): If a user action cuts the parse and thus
2153 yyresolveValue fails, ignore the (unset) semantic value rather than
2154 corrupting the yyGLRState, and empty the semantic options list since
2155 the user actions should have called all necessary destructors.
2156 Simplify code with YYCHK.
2157 * tests/glr-regression.at (Corrupted semantic options if user action
2158 cuts parse): New test case.
2159 (Undesirable destructors if user action cuts parse): New test case.
2160 Before applying any of this patch, this test case never actually failed
2161 for me... but only because the corrupted semantic options usually
2162 masked this bug.
2163 (Leaked merged semantic value if user action cuts parse): New test
2164 case.
2165
2166 2006-01-05 Akim Demaille <akim@epita.fr>
2167

2176 b4_c_modern.
2177 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
2178 than rolling our own.
2179
2180 2006-01-04 Akim Demaille <akim@epita.fr>
2181
2182 Also warn about non-used mid-rule values.

2197 mid-rule, move the `used' bit to its lhs.
2198 * tests/input.at (Unused values): New.
2199 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
2200

2204 --yacc does.
2205 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
2206 about declarations in the grammar when in Yacc mode, as POSIX does
2207 not require a diagnostic when the grammar uses extensions.
2208
2209 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
2210
2211 Warn about dubious constructions like "%token T T".

2220 Allow multiple %union directives, whose contents concatenate.
2221 * src/parse-gram.y (grammar_declaration): Likewise.
2222 Use muscle_code_grow, so that we don't need stype_line any more.
2223 All uses changed.
2224
2225 * src/muscle_tab.c (muscle_grow): Fix comment.
2226
2227 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
2228 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
2229 Update copyright year to 2006.
2230
2231 2006-01-03 Akim Demaille <akim@epita.fr>
2232
2233 Have glr.cc pass (some of) the calc.at tests.
2234 * data/glr.cc (b4_parse_param_orig): New.
2235 (b4_parse_param): Improve its definition, and bound it more
2236 clearly in the skeleton.
2237 (b4_epilogue): Append, instead of prepending, in order to keep
2238 #line consistency.
2239 Simplify the generation of auxiliary functions: locations and
2240 purity are mandated.
2241 (b4_global_tokens_and_yystype): Honor it.
2242 * data/location.cc (c++.m4): Don't include it.
2243 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
2244 and AT_SKEL_CC_IF.

2246 AT_LALR1_CC_IF.
2247 Be sure to initialize the first position's filename.
2248 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
2249 mandated anyway.
2250 (AT_CHECK_CALC_GLR_CC): New.
2251 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
2252
2253 2006-01-02 Akim Demaille <akim@epita.fr>
2254
2255 * src/output.c (output_skeleton): Don't hard wire the inclusion of
2256 c.m4.

2264 * tests/cxx-type.at: Reformat whitespace with tabs.
2265 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
2266 since it's a member. Rename type to isNterm for clarity.
2267
2268 2005-12-29 Akim <akim@sulaco.local>
2269
2270 Let glr.cc catch up with symbol_value_print.

2274
2275 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
2276
2277 * src/location.h (boundary): Note that a line or column equal
2278 to INT_MAX indicates an overflow.
2279 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
2280 (rule_length_overflow, increment_rule_length, add_column_width):
2281 New functions.
2282 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
2283 (<SC_BRACED_CODE>"}"):
2284 Use increment_rule_length rather than incrementing it by hand.
2285 (adjust_location, handle_syncline): Diagnose overflow.
2286 (handle_action_dollar, handle_action_at):
2287 Fix bug with monstrosities like $-2147483648.

2295 GCC warnings.
2296
2297 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
2298
2299 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
2300 Remove unnecessary forward static decls.
2301
2302 2005-12-27 Akim Demaille <akim@epita.fr>
2303
2304 * src/reader.c (grammar_current_rule_check): Also check that $$
2305 is used.
2306 Take the rule to check as argument, hence rename as...
2307 (grammar_rule_check): this.
2308 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
2309 Rename as...
2310 (grammar_rule_begin, grammar_rule_end): these, for consistency.
2311 (grammar_midrule_action, grammar_symbol_append): Now static.
2312 * tests/torture.at (input): Don't rely on the default action
2313 being always performed.
2314 * tests/calc.at: "Set" $$ even when the action is "cut" with
2315 YYERROR or other.
2316 * tests/actions.at (Exotic Dollars): Instead of using unused
2317 values, check that the warning is issued.
2318
2319 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
2320

2330
2331 2005-12-22 Akim Demaille <akim@epita.fr>
2332
2333 * NEWS: Warn about unused values.
2334 * src/symlist.h, src/symlist.c (symbol_list, symbol_list_new): Add

2345 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
2346 * tests/actions.at (Exotic Dollars): Use unused values.
2347 * tests/calc.at: Likewise.

2354 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
2355
2356 Undo 2005-12-01 tentative license wording change. The wording is
2357 still being reviewed by the lawyers, and we don't want to wait for
2358 them before publishing a test release. For now, revert to the
2359 previous wording.
2360 * NEWS: Undo 2005-12-01 change.
2361 * data/glr.c: Revert to previous license wording.
2362 * data/glr.cc: Likewise.
2363 * data/lalr1.cc: Likewise.
2364 * data/location.cc: Likewise.
2365 * data/yacc.c: Likewise.
2366
2367 * NEWS: Reword %destructor vs YYABORT etc.
2368 * data/glr.c: Use American spacing, for consistency.
2369 * data/glr.cc: Likewise.
2370 * data/lalr1.cc: Likewise.
2371 * data/yacc.c: Likewise.
2372 * data/yacc.c: Reformat comments slightly.
2373 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
2374 for consistency. Fix some spelling errors and reword recently-included
2375 text slightly.
2376 * tests/cxx-type.at: Cast results of malloc, for C++.
2377
2378 2005-12-21 Joel E. Denny <address@hidden>
2379
2380 * tests/cxx-type.at: Construct a tree, count the parents of shared
2381 nodes, and free each node once and only once. Previously, the memory
2382 for semantic values was leaked instead.
2383
2384 2005-12-21 Joel E. Denny <address@hidden>
2385
2386 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
2387 (yylval, yylloc): If pure, #define to yystackp->yyval and
2388 yystackp->yyloc similar to yychar and yynerrs.
2389 (yyparse): If pure, remove local yylval and yylloc. Add local
2390 yystackp to accommodate pure definitions of yylval and yylloc.
2391 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
2392 yylvalp and yyllocp to &yylval and &yylloc.
2393 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]

2395 weren't necessary.
2396 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
2397 yylvalp and yyllocp parameters since, if pure, these are now always
2398 accessible through yystackp. If not pure, they are still accessible
2399 globally.
2400 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
2401 `if (YYID (N))' to pacify lint.

2403 2005-12-21 Akim Demaille <akim@epita.fr>
2404
2405 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
2406 destroy the RHS symbols of a rule.
2407 * data/yacc.c (yylen): Initialize to 0.
2408 Keep its value to the number of items to possibly shift.
2409 In particular, a regular successful parse that ends on YYFINAL by
2410 a (internal) YYACCEPT must not have yylen != 0.
2411 (yyerrorlab, yyreturn): Pop the RHS.
2412 Reorder a bit to emphasize the `shifting' bits of code.
2413 (YYPOPSTACK): Now accept a number of items to pop.
2414 * data/lalr1.cc: Likewise.
2415 * data/glr.c: Formatting changes.

2423 * djgpp/config.bat: Replace every occurence of the file name
2424 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
2425 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
2426 * djgpp/config.sed: Replace every occurence of the file name
2427 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
2428 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
2429 * djgpp/djunpack.bat: DJGPP specific file.
2430 * djgpp/fnchange.lst: DJGPP specific file.
2431 * djgpp/README.in: Add new information about how to unpack the bison
2432 source on MSDOS and other systems which have 8.3 file name restrictions
2433 using djunpack.bat and fnchange.lst.

2442
2443 * data/glr.c: Reorder typedef declarations for structs to match order
2444 of struct declarations.
2445 Rename yystack everywhere to yystackp except in yyparse where it's not
2446 a pointer.

2448 consistency.
2449 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
2450 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
2451 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
2452 lint.

2455
2456 * tests/sets.at (Accept): Fix typos in regular expression used to
2457 sed out the final state number.
2458
2459 Work around portability problem on Solaris 10: flex-generated
2460 files include <stdio.h> before <config.h>, which messes up
2461 because the latter defines __EXTENSIONS__. Address the problem
2462 by creating two new little files that include <config.h> first,
2463 then include the flex-generated files. Rewrite everyone else
2464 to include <config.h> first, as well.
2465 * lib/timevar.c: Always include "config.h".
2466 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

2501 (current_assoc): Remove unused variable.
2502
2503 Cleanups so that Bison-generated parsers have less lint.
2504 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
2505 Prepend /*ARGSUSED*/, for lint's sake.
2506 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
2507 definition if 'lint' is defined.
2508 (YYID): New macro (or function, if lint).
2509 All uses of /*CONSTCOND*/0 replaced by YYID(0).
2510 * data/yacc.c: Likewise.
2511 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
2512 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
2513 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
2514 is C++ only.
2515 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
2516 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
2517 Use YYID(0) rather than 0, for lint.
2518 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
2519 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
2520
2521 2005-12-07 Paul Eggert <eggert@cs.ucla.edu>

2537 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
2538
2539 * NEWS: Document the following change.
2540 * data/yacc.c: Say "parser skeleton" rather than "file", since
2541 it's no longer just a file.
2542 * data/glr.c: Grant a special exception for C GLR parsers, that
2543 reads like the already-existing exception for C LALR(1) parsers.
2544 * data/glr.cc: Likewise.
2545 * data/lalr1.cc: Likewise.
2546 * data/location.cc: Likewise.
2547 * data/yacc.c: Reword the "written by" statement to clarify that
2548 it was the parser skeleton, not the entire output file.
2549 * data/glr.c: Written by Paul Hilfinger.
2550 * data/glr.cc: Written by Akim Demaille.
2551 * data/lalr1.cc: Likewise.
2552

2554
2555 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
2556 Fix typos in previous change that broke 'make check'.
2557 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
2558 supported in C.
2559 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
2560 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
2561 We can revert this once things settle down.
2562
2563 * src/conflicts.c (conflicts_print): Don't print file name twice
2564 when %expect fails because there were no conflicts.
2565 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
2566 change.
2567 * tests/conflicts.at (%expect not enough, %expect too much):
2568 (%expect with reduce conflicts): Adjust to new behavior.

2591
2592 2005-11-14 Akim Demaille <akim@epita.fr>
2593
2594 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
2595 from 1 to N, while values and location start at 0.
2596 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
2597
2598 2005-11-14 Akim Demaille <akim@epita.fr>
2599
2600 * data/glr.c (yy_reduce_print): Fix the $ number.

2629 2005-11-12 Akim Demaille <akim@epita.fr>
2630
2631 * data/lalr1.cc: Move the body of the ctor and dtor into the
2632 parser file (instead of the header).
2633 Wrap the implementations in a "namespace yy".
2634
2635 2005-11-12 Akim Demaille <akim@epita.fr>
2636
2637 Have glr.c include its header file when created.
2638 * data/glr.c (b4_shared_declarations): New.
2639 Output them verbatim in the parser if !%defines, otherwise
2640 output then in the header file, and include it instead.
2641
2642 2005-11-11 Akim Demaille <akim@epita.fr>
2643
2644 * data/glr.c: Comment changes.
2645
2646 2005-11-11 Akim Demaille <akim@epita.fr>

2665
2666 * m4/cxx.m4, examples/Makefile.am: Don't build
2667 examples/calc++ if no C++ compiler is available. (trivial change)
2668
2669 2005-11-09 Akim Demaille <akim@epita.fr>
2670
2671 * src/scan-skel.l: Use a couple of asserts.
2672
2673 2005-11-03 Akim Demaille <akim@epita.fr>
2674
2675 In some (weird) cases, the final state number is incorrect.
2676 Reported by Alexandre Duret-Lutz.
2677 * src/LR0.c (state_list_append): Remove the computation of
2678 final_state.
2679 (save_reductions): Do it here.
2680 (get_state): Alpha conversion.
2681 (generate_states): Use a for loop.

2692 for empty right-hand sides.
2693 (yydoAction): Ditto.
2694 Add comment explaining apparently dead code.

2697 New test.
2698
2699 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
2700
2701 * bootstrap (cleanup_gnulib): New function. Use it to clean up
2702 gnulib when interrupted. This fixes some race conditions and
2703 works around some portability problems (one noted by Paul
2704 Hilfinger).
2705
2706 2005-10-22 Akim <akim@epita.fr>
2707
2708 * Makefile.cfg: Adjust to config -> build-aux.
2709 Reported by twledo.

2726 Move to...
2727 * build-aux/prev-version, build-aux/announce-gen,
2728 * build-aux/Makefile.am: here.
2729
2730 2005-10-14 Akim Demaille <akim@epita.fr>
2731
2732 * examples/calc++/test: Use set -x only when VERBOSE.
2733
2734 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
2735
2736 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
2737 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
2738
2739 2005-10-13 Akim Demaille <akim@epita.fr>
2740
2741 * src/scan-skel.l: Output the base name parts of the parser and
2742 header file names.
2743 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
2744 additional checks.
2745 Use this to exercise C++ outputs in subdirs.
2746 Reported by Oleg Smolsky.
2747
2748 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
2749
2750 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
2751 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
2752 Problem reported by John P. Hartmann.
2753 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
2754 already defined it.
2755
2756 2005-10-12 Akim Demaille <akim@epita.fr>
2757
2758 * src/parse-gram.y (version_check): Exit 63 to please missing

2770 * src/scan-skel.l (skel_wrap): Likewise.
2771 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
2772 as __STDC__.
2773 * data/yacc.c (YYMODERN_C): New macro, which also looks at
2774 __STDC_VERSION__. Use it everywhere instead of looking at
2775 __STDC__ and __cplusplus.
2776
2777 2005-10-10 Akim Demaille <akim@epita.fr>
2778
2779 * examples/calc++/test: Be quiet unless VERBOSE.

2789 (YYCHK1):
2790 Use /*CONSTCOND*/ to suppress lint warnings.
2791 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
2792 (YY_STACK_PRINT): Use 'false' not '0'.

2797 (YYDPRINTF, YY_SYMBOL_PRINT, YY_STACK_PRINT, YY_REDUCE_PRINT):
2798 (yyerrorlab): Use /*CONSTCOND*/ to suppress lint warnings.
2799
2800
2801 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.

2803
2804 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
2805
2806 Undo the parts of the unlocked-I/O change that substituted
2807 putc or puts for printf. This might hurt performance a bit,
2808 but some people prefer the printf style.
2809 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
2810 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

2820 * src/output.c (escaped_output): Likewise.
2821 (user_actions_output): Break apart two printfs.

2826
2827 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
2828 Use assignments rather than casts-to-void to suppress
2829 unused-variable warnings. This pacifies 'lint'.

2831 unused-variable warnings.
2832
2833 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2834

2836
2837 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
2838
2839 Use unlocked I/O for a minor performance improvement on hosts like
2840 GNU/Linux and Solaris that support unlocked I/O. The basic idea
2841 is to use the gnlib unlocked-io module, and to prefer putc and
2842 puts to printf when either will work (since the latter doesn't
2843 come in an unlocked flavor).
2844 * bootstrap (gnulib_modules): Add unlocked-io.
2845 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
2846 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

2848 and similarly for puts and putc and printf.
2849 * data/yacc.c: Likewise.
2850 * lib/bitset.c (bitset_print): Likewise.
2851 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

2855 * src/closure.c (print_firsts, print_fderives): Likewise.
2856 * src/gram.c (grammar_dump): Likewise.
2857 * src/lalr.c (look_ahead_tokens_print): Likewise.
2858 * src/output.c (escaped_output): Likewise.
2859 (user_actions_output): Coalesce two printfs.

2862 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
2863 * src/system.h: Include unlocked-io.h rather than stdio.h.
2864
2865 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
2866 this confuses xgettext.

2907
2908 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2909
2910 * lib/subpipe.c: New function end_of_output_subpipe() added
2911 to allow support for non-posix systems. This is a no-op function
2912 for posix systems.
2913
2914 * lib/subpipe.h: New function end_of_output_subpipe() added
2915 to allow support for non-posix systems. This is a no-op function
2916 for posix systems.
2917
2918 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
2919 handle the lack of pipe/fork functionality on non-posix systems.

2939 * data/location.cc: New, extract from...
2940 * data/lalr1.cc: here.
2941 (location.hh): Include it after the user prologue, in case the
2942 filename type is defined by the user.
2943 Forward declation location and position before the pre-prologue.
2944 (yyresult_): Rename as...
2945 (yyresult): this, it's a local variable, not an attribute.
2946 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
2947
2948 2005-10-01 Akim Demaille <akim@epita.fr>

2960 (b4_post_prologue): No longer included in the header file, but
2961 in the implementation file.
2962 * doc/bison.texi (C+ Language Interface): Update.
2963 * src/parse-gram.y: Support unary %define.
2964 * tests/actions.at: Define global_tokens_and_yystype for backward
2965 compatibility until we update the tests.
2966 * tests/calc.at: Idem.
2967 (first_line, first_column, last_line, last_column): Define for lalr1.cc
2968 to simplify the code.
2969
2970 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
2971
2972 Port to SunOS 4.1.4, which lacks strtoul and strerror.
2973 Ah, the good old days! Problem reported by Peter Klein.
2974 * bootstrap (gnulib_modules): Add strerror, strtoul.
2975 * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
2976 * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.
2977
2978 2005-09-29 Akim Demaille <akim@epita.fr>
2979
2980 * data/c.m4 (b4_error_verbose_if): New.
2981 * data/lalr1.cc: Use it.
2982 (YYERROR_VERBOSE_IF): Remove.
2983 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
2984 parser members, replaced by...
2985 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
2986 local variables.
2987 (yysyntax_error_): Takes the state number as argument.
2988 (yyreduce_print_): Use the argument yyrule, not the former
2989 attribute yyn_.
2990
2991 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
2992
2993 * bootstrap (gnulib_modules): Add verify.
2994 * lib/.cvsignore: Add verify.h.
2995 * src/getargs.c: Use ARGMATCH_VERIFY rather than verify.
2996 * src/system.h (verify): Remove.
2997 Include verify.h instead.
2998 * src/tables.c (tables_generate): Use new API for 'verify'.
2999
3000 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
3001
3002 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
3003 local variables whose names begin with 'yy'.
3004 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
3005 Trivial changes from Joel E. Denny.
3006
3007 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
3008 it itself.
3009 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
3010 don't use alloca any more.
3011
3012 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
3013 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
3014 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
3015 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
3016 to match yacc.c, to test more hosts.
3017
3018 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
3019
3020 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
3021 doesn't affect behavior.
3022 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
3023 Solaris, AIX, MSC.
3024 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
3025 This works a bit better with glibc, if user code has already included
3026 stdlib.h.
3027 * doc/bison.texinfo (Bison Parser): Document that users can't
3028 arbitrarily use malloc and free for other purposes. Document
3029 that <alloca.h> and <malloc.h> might be included.
3030 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
3031 user must declare alloca.
3032
3033 * HACKING (release): Forwarn the Translation Project about
3034 stable releses.
3035
3036 2005-09-20 Akim Demaille <akim@epita.fr>

3039
3040 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
3041
3042 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
3043 (YYSTACK_ALLOC_MAXIMUM): Use it.
3044 (yysyntax_error): New function.
3045 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
3046 multiple syntax errors are reported, and alloca is being used.
3047 Instead, reallocate buffers twice as big each time, so that
3048 we waste at most half the allocated memory. Start with a small
3049 (128-byte) buffer that will suffice in most cases anyway.
3050 Use yysyntax_error to do most of the work.
3051
3052 * doc/bison.texinfo (Error Reporting, Table of Symbols):
3053 yynerrs is the number of errors reported, not the number of
3054 errors encountered.
3055
3056 * tests/glr-regression.at (Duplicated user destructor for lookahead):
3057 Mark it as expected to fail.
3058 Cast result of malloc; problem reported by twlevo@xs4all.nl.
3059 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
3060 Don't start user-code symbols with "yy", to avoid name space problems.
3061
3062 2005-09-19 Akim Demaille <akim@epita.fr>
3063
3064 Remove the traits, failed experiment.
3065 It never proved useful, and anyway because of the current
3066 definition, it was not possible to have several specialization of
3067 this traits, making it useless.
3068 * data/lalr1.cc (yy:traits): Remove.
3069 Inline its definitions in the parser class.
3070
3071 2005-09-19 Akim Demaille <akim@epita.fr>
3072
3073 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
3074 least Mac OSX with a /usr/local install of gettext.
3075
3076 2005-09-19 Akim Demaille <akim@epita.fr>
3077
3078 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
3079 and yytoken for similarity with the other skeletons.
3080
3081 2005-09-19 Akim Demaille <akim@epita.fr>
3082
3083 * NEWS, configure.ac: update version number to 2.1a.
3084

3086
3087 * NEWS: Version 2.1.

3089 * NEWS: Remove notice of yytname change, since it was never in an
3090 official release.
3091 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
3092 diagnostic.
3093 * src/output.c (prepare): Likewise.
3094 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
3095 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
3096 is not defined. This is an awful hack, but it's enough for now.
3097 All callers changed.
3098 * tests/glr-regression-at (make_value): Args are const pointers now,
3099 to avoid GCC warning.
3100 (Duplicated user destructor for lookahead): New test. Currently
3101 skipped. It fails on my host but I'm not sure it'll always fail.
3102
3103 2005-09-16 Akim Demaille <akim@epita.fr>
3104
3105 * src/symtab.h (struct symbol): Declare the printer and destructor
3106 as const, to avoid accidental calls to free.
3107 (symbol_destructor_set, symbol_printer_set): Adjust.
3108 * src/symtab.c: Adjust.
3109
3110 2005-09-16 Akim Demaille <akim@epita.fr>
3111
3112 * data/c.m4 (b4_token_enums): New.
3113 (b4_token_defines): Rename as...
3114 (b4_token_enums_defines): this.
3115 (b4_token_defines): New, output only the #defines.
3116 * data/yacc.c, data/glr.c: Adjust.
3117 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
3118 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
3119 as default values.
3120
3121 2005-09-16 Akim Demaille <akim@epita.fr>
3122
3123 * data/lalr1.cc (yylex_): Remove, inline its code.
3124 (yyreport_syntax_error_): Remove, replaced by...
3125 (yysyntax_error_): this which returns a string and leaves to the
3126 caller the call to the users' error function.
3127 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
3128 Move from members of the parser object...
3129 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
3130 to local variables of the parse function.
3131
3132 2005-09-16 Akim Demaille <akim@epita.fr>
3133
3134 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
3135 since it's in Bison's name space.
3136
3137 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
3138
3139 * data/glr.c (yyresolveValue): Add default case to pacify
3140 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
3141
3142 * NEWS: Document when yyparse started to return 2.
3143 * doc/bison.texinfo (Parser Function): Document when yyparse
3144 returns 2.
3145
3146 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
3147 (b4_filename_type): Renamed back from b4_file_name_type. All uses
3148 changed.
3149 (class position): file_name -> filename (reverting). All uses changed.
3150
3151 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
3152
3153 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
3154 do anything if $@ exists. This reverts part of the 2005-07-07
3155 patch.
3156
3157 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
3158
3159 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
3160 contains obsolete information and isn't worth distributing as a
3161 separate file anyway.
3162 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
3163 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
3164 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
3165 (yyparse): Abort if user code uses longjmp to throw an unexpected
3166 value.
3167
3168 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
3169
3170 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
3171 Suggested by twlevo@xs4all.nl.
3172
3173 * data/glr.c (YYCHK1): Do not assume YYE is in range.
3174 This avoids a diagnostic from gcc -Wswitch-enum.
3175 Problem reported by twlevo@xs4all.nl.
3176
3177 * doc/bison.texinfo: Don't use "filename", as per GNU coding
3178 standards. Use "file name" or "file" or "name", depending on
3179 the context.
3180 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
3181 not to hack/foo.tab.c.
3182 (Calc++ Top Level): 2nd arg of main is not const.
3183 * data/glr.c: b4_filename -> b4_file_name.
3184 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
3185 All uses changed.
3186 (class position): filename -> file_name. All uses changed.
3187 * data/yacc.c: b4_filename -> b4_file_name.
3188 * lib/bitset.h: filename -> file_name in local vars.
3189 * lib/bitset_stats.c: Likewise.
3190 * src/files.c: Likewise.
3191 * src/scan-skel.l ("@output ".*\n): Likewise.
3192 * src/files.c (file_name_split): Renamed from filename_split.
3193 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
3194
3195 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
3196
3197 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
3198 to accommodate latest gnulib.
3199
3200 * tests/glr-regression.at (Duplicate representation of merged trees):
3201 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
3202
3203 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
3204 needed.
3205
3206 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3207
3208 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
3209 All uses changed. Invoke user destructor after an error during a
3210 split parse (trivial change from Joel E. Denny).
3211
3212 * tests/glr-regression.at
3213 (User destructor after an error during a split parse): New test case.
3214 Problem reported by Joel E. Denny in:
3215 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
3216
3217 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3218
3219 * README-cvs: Give URLs for recommended tools.
3220 Mention Gzip version problem, and bootstrapping issues.
3221 Remove troubleshooting section, as it's somewhat obsolete.
3222
3223 * bootstrap (no_cache): New var, to accommodate different wget
3224 variants. Use it instead of '-C off'. Problem reported by
3225 twlevo@xs4all.nl.
3226
3227 * data/glr.c (yydestroyStackItem): New function.
3228 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
3229 debugging information. Problem reported by Joel E. Denny.
3230
3231 2005-08-25 Akim Demaille <akim@epita.fr>
3232
3233 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
3234
3235 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
3236

3238 Don't invoke destructor on unresolved entries.
3239 * tests/glr-regression.at
3240 (User destructor for unresolved GLR semantic value): New test case.
3241 Problem reported by Joel E. Denny in:
3242 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
3243
3244 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
3245
3246 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
3247 Add strnlen.c.
3248 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
3249 lib-prefix.m4, po.m4.
3250
3251 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
3252 in yydestruct diagnostic, since it might not be an error.
3253 Problem reported by Joel Denny near end of
3254 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
3255 * data/lalr1.cc (yyerturn): Likewise.
3256 * data/yacc.c (yyreturn): Likewise.
3257 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
3258
3259 * src/files.c: Remove obsolete FIXME comment.
3260
3261 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
3262 with the other templates, and to fix bogus run-on messages such
3263 as the one reported at the end of
3264 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
3265 All callers changed to avoid the newline.
3266 (yyprocessOneStack): Output two lines rather than one, to accommodate
3267 the above change. This changes the debug output format slightly.
3268
3269 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
3270 reported by Joel E. Denny in
3271 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
3272 (trivial change).
3273 * tests/glr-regression.at (Duplicate representation of merged trees):
3274 New test, from Joel E. Denny in:
3275 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
3276 * THANKS: Add Joel E. Denny.
3277
3278 * configure.ac (AC_INIT): Bump to 2.0c.
3279
3280 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
3281
3282 * NEWS: Version 2.0b.
3283
3284 * Makefile.am (SUBDIRS): Put examples before tests, so that
3285 "make check" doesn't finish with "All 1 tests passed".
3286
3287 * tests/regression.at (Token definitions): Don't rely on
3288 AT_PARSER_CHECK for data that contains backslashes. It currently
3289 uses 'echo', and 'echo' isn't portable if its argument contains
3290 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
3291 that the byte '\0xff' is not printable in the C locale; it is,
3292 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
3293 not printable, so use '\0x81' to test.
3294
3295 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
3296 version of GCC, since the macro is used with non-GCC compilers.
3297
3298 Fix core dump reported by Pablo De Napoli in
3299 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
3300 * tests/regression.at (Invalid inputs with {}): New test.
3301 * src/parse-gram.y (token_name): Translate type before using
3302 it as an index.
3303
3304 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
3305 the user's name space. All uses changed to __attribute__
3306 ((__unused__)).
3307 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
3308 Add __attribute__ ((__noreturn__)).
3309
3310 * etc/clcommit: Remove. We weren't using it, and it failed
3311 "make maintainer-distcheck".
3312 * Makefile.maint: Merge from coreutils.
3313 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
3314 (syntax-check-rules): Change list of rules as described below.
3315 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
3316 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
3317 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
3318 (sc_trailing_space): New rules.
3319 (sc_xalloc_h_in_src): Remove.
3320 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
3321 (sc_space_tab, sc_error_exit_success, sc_changelog):
3322 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
3323 (makefile-check, po-check, author_mark_check):
3324 (makefile_path_separator_check, copyright-check):
3325 Use grep -n, to make it easier to find violations.
3326 Use CVS_LIST and CVS_LIST_EXCEPT.
3327 (header_regexp, h_re): Remove.
3328 (dd_c): New macro.
3329 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
3330 (my-distcheck): Use more-modern GCC flags.
3331 (signatures, %.asc): Remove.
3332 (rel-files, announcement): Remove signatures.
3333 Restore old updating code, even though we don't use it, so
3334 that we're the same as coreutils.
3335 (alpha, beta, major): Depend on news-date-check.
3336 Make the upload commands.
3337
3338 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

3345 * tests/sets.at: Likewise.
3346
3347 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
3348 we comment out the Autoconf version number.
3349 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
3350 it's error-prone and "make maintainer-distcheck" rejects it.
3351
3352 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
3353 Indent calls to "error" to pacify "make maintainer-distcheck",
3354 when the calls are not intended to be translated.
3355 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
3356
3357 * src/Makefile.am (DEFS): Use +=, to pacify
3358 "make maintainer-distcheck".
3359 (bison_SOURCES): Add scan-skel.h.
3360 (sc_tight_scope): New rule, from coreutils.
3361
3362 * src/files.c (src_extension, header_extension):
3363 Now static, not extern.
3364 * src/getargs.c (short_options): Likewise.
3365 * src/muscle_tab.c (muscle_table): Likewise.
3366 * src/parse-gram.y (current_class, current_type, current_prec):
3367 Likewise.
3368 * src/reader.c (grammar_end, previous_rule_end): Likewise.
3369 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
3370 * src/main.c (main): Cast bindtextdomain and textdomain calls to
3371 void, to avoid warning when NLS is disabled.
3372 * src/output.c: Include scan-skel.h.
3373 (scan_skel): Remove decl, since scan-skel.h does this.
3374 (output_skeleton):
3375 Indent calls to "error" to pacify "make maintainer-distcheck".
3376 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
3377 * src/reader.h (gram_end, gram_lineno): New decls to pacify
3378 "make maintainer-distcheck".
3379 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
3380 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
3381 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
3382 (skel_lex_destroy, scan_skel): Move these decls to...
3383 * src/scan-skel.h: New file.
3384 * src/uniqstr.c (uniqstr_assert):
3385 Indent calls to "error" to pacify "make maintainer-distcheck".
3386
3387 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
3388 not @VAR@.
3389
3390 * tests/torture.at: Revamp to avoid misuse of atoi that
3391 "make maintainer-distcheck" complained about.
3392
3393 * examples/extexi (message): Don't print a message more than once,
3394 and omit line-number decoration that makes Emacs compile think
3395 that informative messages are worth worrying about.
3396
3397 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
3398
3399 * configure.ac: Update version number.
3400
3401 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
3402 accidentally.
3403 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
3404 autogenerated by the maintainer.
3405 * examples/calc++/.cvsignore: Add *.yy.
3406
3407 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
3408 * lib/bitset_stats.c (bitset_stats_init): Likewise.
3409 * lib/bitsetv.c (bitsetv_alloc): Likewise.
3410
3411 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
3412
3413 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
3414 from maintainer-distcheck about casting the argument of 'free'.
3415
3416 * NEWS: Mention recent yytname changes.
3417 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
3418
3419 * bootstrap: For translations that have not yet been upgraded to
3420 the new runtime-po domain, prime the pump by extracting the
3421 relevant strings from the obsolete translations. This code can be
3422 removed once the bison-runtime domain has been translated by each
3423 team.
3424
3425 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
3426 now that token names are already quoted.
3427
3428 Fix problem reported by Anthony Heading.
3429 * data/glr.c (YYTOKEN_TABLE): New macro.
3430 (yytname): Define if YYTOKEN_TABLE.
3431 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
3432 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
3433 (YYERROR_VERBOSE): Define the same way the other skeletons do.
3434 * src/output.c (prepare_symbols): Output token_table_flag.
3435
3436 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
3437
3438 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
3439 again if the first call fails.
3440
3441 * data/glr.c (yytnamerr): New function.
3442 (yyreportSyntaxError): Use it to dequote most string literals.
3443 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
3444 with other skeletons. All uses changed.
3445 (yytnameerr_): New function.
3446 (yyreport_syntax_error): Use it to dequote most string literals.
3447 * data/yacc.c (yytnamerr): New function.
3448 (yyerrlab): Use it to decode most string literals.
3449 * doc/bison.texinfo (Decl Summary, Calling Convention):
3450 Clarify quoting convention of yytname.
3451 * src/output.c (prepare_symbols): Quote all names. This undoes
3452 the 2005-04-17 change, which is now accomplished (mostly) via
3453 changes in the parsers as described above.
3454 * tests/regression.at (Token definitions, Web2c Actions):
3455 Undo most 2005-04-17 change here, too.
3456
3457 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
3458
3459 Fix more problems reported by twlevo@xs4all.nl.
3460 * tests/cxx-type.at: Don't pipe output of ./types through sed to
3461 remove trailing spaces. This loses the exit status of ./types,
3462 and isn't needed since ./types shouldn't be emitting trailing
3463 spaces.
3464 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
3465 as the stack isn't valid in that case.
3466
3467 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
3468 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
3469 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
3470 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
3471 is used.
3472 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
3473 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
3474 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
3475 Likewise.
3476
3477 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
3478 overly-picky compilers that reject 'char *foo = "bar";'.
3479
3480 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
3481 to FILE * parameter, not to stderr. This fixes a typo introduced
3482 in the 2005-07-12 change.
3483
3484 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
3485 warnings from GCC 4.
3486
3487 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
3488 (yyglrShiftDefer, yysplitStack):
3489 Remove unused parameters b4_pure_formals. All uses changed.
3490 (yyglrShift): Remove unused parameters b4_user_formals.
3491 All uses changed.
3492 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
3493
3494 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
3495
3496 Destructor cleanups and regularization among the three skeletons.
3497 * NEWS: Document the behavior changes.
3498 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
3499 stack before failing, as the cleanup code will do it for us now.
3500 * data/lalr1.cc (yyerrlab): Likewise.
3501 * data/glr.c (yyparse): Pop everything off the stack before
3502 freeing it, so that destructors get called properly.
3503 * data/lalr1.cc (yyreturn): Likewise.
3504 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
3505 This is more consistent.
3506 * doc/bison.texinfo (Destructor Decl): Mention more reasons
3507 why destructors might be called. 1.875 -> 2.1.
3508 (Destructor Decl, Decl Summary, Table of Symbols):
3509 Some English-language cleanups for %destructor.
3510 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3511 Add output line for destructor of start symbol.
3512 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
3513 because of that same extra output line.
3514
3515 * NEWS: Document minor wording changes in diagnostics of
3516 Bison-generated parsers.
3517 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
3518 Remove unused formals. All uses changed.
3519 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
3520 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
3521 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
3522 Rename yyoverflowab to yyexhaustedlab.
3523 When memory exhaustion occurs during syntax-error reporting,
3524 report it separately rather than in a single diagnostic; this
3525 eases translation.
3526 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
3527 (Memory Exhausted): Renamed from Parser Stack Overflow.
3528 Revamp wording slightly to prefer "memory exhaustion".
3529 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
3530
3531 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
3532
3533 Add i18n support to the GLR skeleton. Partially fix the C++
3534 skeleton; a C++ expert needs to finish this. Remove debugging
3535 msgids; there's little point to having them translated, since they
3536 can be understood only by someone who can read the
3537 (English-language) source code.
3538
3539 Generate runtime-po/bison-runtime.pot automatically, so that we
3540 don't have to worry about garbage getting in that file. We'll
3541 make sure after the next official release that old msgids don't
3542 get lost. See
3543 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
3544
3545 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
3546 Now auto-generated.
3547 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
3548 Fix typos in explanations of the runtime file.
3549 * bootstrap: Change gettext keyword from YYI18N to YY_.
3550 Use standard Makefile.in.in in runtime-po, since we'll arrange
3551 for backward-compatible bison-runtime.po files in a different way.
3552 * data/glr.c (YY_): New macro, from yacc.c.
3553 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
3554 Translate messages intended for users.
3555 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
3556 the wording in the other skeletons. We don't know that the memory
3557 is virtual.
3558 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
3559 Use same method that yacc.c uses.
3560 Don't translate debugging messages.
3561 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
3562 it doesn't work (yet), and requires C++ expertise to fix.
3563 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
3564 Move defn to a more logical place, to be consistent with other
3565 skeletons.
3566 Don't translate debugging messages.
3567 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
3568 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
3569 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
3570 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
3571
3572 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
3573 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
3574 void, not int.
3575 * tests/glr-regression.at (Badly Collapsed GLR States):
3576 Likewise.
3577 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3578 yylex should return 0 at EOF rather than aborting.
3579
3580 Improve tests for stack overflow in GLR parser.
3581 Problem reported by twlevo@xs4all.nl.
3582 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
3583 All uses removed.
3584 (yyStackOverflow): Just longjmp, but with value 2 so that caller
3585 can handle the problem.
3586 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
3587 (yyparse): New local variable yyresult to record the result.
3588 Use result of setjmp to set it, rather than storing itinto
3589 struct.
3590 (yyDone): Remove label.
3591 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
3592 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
3593 if YYABORT is used).
3594 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
3595 yyparse status; put status > 1 into diagnostic.
3596 Check that status==2 works.
3597 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
3598 Use exit status 3 for failure to open (which shouldn't happen).
3599
3600 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
3601
3602 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
3603 1 on syntax error; just let yyparse do its thing.
3604 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
3605 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
3606 (Exploding the Stack Size with Alloca):
3607 (Exploding the Stack Size with Malloc):
3608 Expect exit status 2, not 1, since the parser is supposed to blow
3609 its stack. Problem reported by twlevo@xs4all.nl.
3610
3611 * data/glr.c (yyparse): Don't assume that the initial calls
3612 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
3613 Print a stack-overflow message and fail instead.
3614 Initialize the line-number information before creating the stack,
3615 so that the stack-overflow message can report line zero safely.
3616
3617 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
3618
3619 Fix problems reported by twlevo@xs4all.nl.
3620 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
3621 (yyuserMerge): Provide a default case if b4_mergers is empty.
3622 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
3623 * tests/glr-regression.at
3624 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3625 Add casts to pacify C++ compilers.
3626 * tests/glr-regression.at (Improper merging of GLR delayed action
3627 sets): Declare yylex before using it.
3628 * tests/Makefile.am (maintainer-check-g++): Fix a stray
3629 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
3630 test for valgrind; valgrind is independent of g++.
3631 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
3632 for compatibility with POSIX 1003.1-2001 (if running coreutils).
3633 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
3634 Use a destructor, so that we can expand the stack. Change
3635 YYSTYPE to char * so that we can free it. Cast result of malloc.
3636
3637 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3638
3639 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
3640 a valgrind failure. Problem reported by twlevo@xs4all.nl.
3641
3642 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
3643
3644 * PACKAGING: New file, suggested by Bruno Haible and taken from
3645 similar wording in gettext's PACKAGING file.
3646 * NEWS: Mention PACKAGING.
3647 * Makefile.am (EXTRA_DIST): Add PACKAGING.
3648
3649 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
3650
3651 * NEWS: Document recent i18n improvements.
3652 * bootstrap: Get runtime translations into runtime-po.
3653 Create runtime-po files automatically, if possible.
3654 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
3655 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
3656 does not infringe on the user's name space.
3657 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
3658 * doc/bison.texinfo (Internationalization): Revamp the English
3659 and Texinfo syntax a bit, to try to make it clearer.
3660 (Bison Options, Option Cross Key): Mention --print-localedir.
3661 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
3662 YYENABLE_NLS. Quote a bit more.
3663 * runtime-po/.cvsignore: New file.
3664 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
3665 * runtime-po/Rules-quot: Remove; now created by bootstrap.
3666 * runtime-po/quot.sed: Likewise.
3667 * runtime-po/boldquot.sed: Likewise.
3668 * runtime-po/en@quot.header: Likewise.
3669 * runtime-po/en@boldquot.header: Likewise.
3670 * runtime-po/insert-header.sin: Likewise.
3671 * runtime-po/remove-potcdate.sin: Likewise.
3672 * runtime-po/Makevars: Likewise.
3673 * runtime-po/LINGUAS: Likewise.
3674 * runtime-po/de.po: Likewise; we will rely on the translation project
3675 to maintain this, so "bootstrap" should get it.
3676 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
3677 its value.
3678 * src/main.c (main): Bind the bison-runtime domain, too.
3679
3680 2005-07-12 Bruno Haible <bruno@clisp.org>
3681
3682 * data/yacc.c: Include <libintl.h> when NLS is enabled.
3683 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
3684 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
3685 * runtime-po: New directory.
3686 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
3687 $(DOMAIN).pot-update rule, so that old messages are never dropped.
3688 * runtime-po/Rules-quot: New file, copied from po/.
3689 * runtime-po/quot.sed: Likewise.
3690 * runtime-po/boldquot.sed: Likewise.
3691 * runtime-po/en@quot.header: Likewise.
3692 * runtime-po/en@boldquot.header: Likewise.
3693 * runtime-po/insert-header.sin: Likewise.
3694 * runtime-po/remove-potcdate.sin: Likewise.
3695 * runtime-po/Makevars: New file.
3696 * runtime-po/POTFILES.in: New file.
3697 * runtime-po/LINGUAS: New file.
3698 * runtime-po/bison-runtime.pot: New file.
3699 * runtime-po/de.po: New file.
3700 * m4/bison.m4: New file.
3701 * Makefile.am (SUBDIRS): Add runtime-po.
3702 (aclocaldir, aclocal_DATA): New variables.
3703 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
3704 Define aclocaldir.
3705 * src/getargs.c (usage): Document --print-localedir option.
3706 (PRINT_LOCALEDIR_OPTION): New enum item.
3707 (long_options): Add --print-localedir option.
3708 (getargs): Handle --print-localedir option.
3709 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
3710 (Internationalization): New section.
3711
3712 2005-07-12 Akim Demaille <akim@epita.fr>
3713
3714 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
3715 for consistency with the rest of the code.
3716 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
3717 Add separators.
3718
3719 2005-07-12 Akim Demaille <akim@epita.fr>
3720
3721 * src/parse-gram.y: Use %printer instead of YYPRINT.
3722
3723 2005-07-12 Akim Demaille <akim@epita.fr>
3724
3725 * src/symtab.h, src/symtab.c (symbol_print): New.
3726 * src/symlist.h, src/symlist.c (symbol_list_print): New.
3727 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
3728
3729 2005-07-12 Akim Demaille <akim@epita.fr>
3730
3731 * data/glr.c (b4_syncline): Fix (swap) the definitions of
3732 b4_at_dollar and b4_dollar_dollar.
3733
3734 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
3735
3736 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
3737 and Pennello's paper.
3738
3739 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
3740
3741 * data/yacc.c (yyparse): Undo previous patch. Instead,
3742 set yylsp[0] and yyvsp[0] only if the initial action
3743 sets yylloc and yylval, respectively.
3744
3745 * data/yacc.c (yyparse): In the initial action, set
3746 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
3747 This avoids the use of undefined variables if the initial
3748 action does not set yylloc and/or yylval.
3749
3750 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3751
3752 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
3753 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
3754 Remove from CVS. These files are automatically generated.
3755 * examples/extexi: Clarify that this file is now part of Bison,
3756 not GNU M4, and that it works with any POSIX-compatible Awk.
3757 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
3758 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
3759 so that we also get calc++-parser.yy. Geneate it.
3760 Use $(AWK), not gawk, since any conforming Awk will do.
3761 Put comment before action, since older 'make' can't handle comment
3762 in action.
3763 $(BUILT_SOURCES): List all built sources, not just some of them.
3764 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
3765 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
3766 $($(calc_sources_generated)): Remove unnecessary test for existence
3767 of target. (This had a shell syntax error anyway; a stray "x".)
3768 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
3769 calc++-parser.yy.
3770 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
3771
3772 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
3773 implied by the other modules.
3774
3775 2005-07-06 Akim Demaille <akim@epita.fr>
3776
3777 Bind examples/calc++ to the package.
3778 * examples/calc++/Makefile: Remove, replaced by...
3779 * examples/calc++/Makefile.am: ... this new file.
3780 * examples/calc++/test: Remove input.
3781 * examples/calc++/compile: Remove.
3782 * examples/Makefile.am: New.
3783 * configure.ac, Makefile.am: Adjust.
3784 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
3785
3786 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
3787
3788 * data/glr.c (yyFail): Drastically simplify; since the format argument
3789 never had any % directives, we can simply pass it to yyerror.
3790 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
3791 be modified later, as that is the usual style in glr.c.
3792 Problems reported by Paul Hilfinger.
3793
3794 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
3795 and size overflow errors.
3796 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
3797 in case the user prolog sets feature-test macros like _GNU_SOURCE.
3798 (YYSIZEMAX): New macro.
3799 (yystpcpy): New function, taken from yacc.c.
3800 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
3801 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
3802 so that we don't have to maintain their signatures.
3803 (yyFail): Check for buffer overflow, by using vsnprintf rather
3804 than vsprintf. Allocate a bigger buffer if possible.
3805 Report an error if buffer allocation fails.
3806 (yyStackOverflow): New function.
3807 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
3808 the initialization was successful. It might fail if storage was
3809 exhausted.
3810 (yyexpandGLRStack): Add more checks for storage allocation failure.
3811 Use yyStackOverflow to report failures.
3812 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
3813 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
3814 Don't assume stack number fits in int.
3815 (yysplitStack): Check for storage allocation failure.
3816 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
3817 can print diagnostics on storage allocation failure. All callers
3818 changed.
3819 (yyresolveValue): Use yybool for boolean.
3820 (yyreportSyntaxError): Check for size-calculation overflow.
3821 This code is taken from yacc.c.
3822 (yyparse): Check for storage allocation errors when allocating
3823 the initial stack.

3825 2005-07-05 Akim Demaille <akim@epita.fr>
3826
3827 Extract calc++ from the documentation.
3828 * doc/bison.texinfo (Calc++): Add the extraction marks.
3829 * examples/extexi: New, from the aborted GNU Programming 2E.
3830 Separate the different paragraph of a file with empty lines.
3831 * examples/Makefile: Use it to extract the whole calc++ example.
3832
3833 2005-06-24 Akim Demaille <akim@epita.fr>
3834
3835 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
3836 class typedefs.
3837
3838 2005-06-22 Akim Demaille <akim@epita.fr>
3839
3840 * doc/bison.texinfo (C++ Language Interface): First stab.
3841 (C++ Parsers): Remove.
3842
3843 2005-06-22 Akim Demaille <akim@epita.fr>
3844
3845 * data/lalr1.cc (yylex_): Honor %lex-param.
3846
3847 2005-06-22 Akim Demaille <akim@epita.fr>
3848

3855
3856 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
3857
3858 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
3859 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
3860 which stems from the 2005-05-27 patch.
3861
3862 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
3863
3864 * data/glr.c: Modify treatment of unused parameters to permit use
3865 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
3866
3867 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
3868
3869 Fix infringement on user name space reported by Janos Zoltan Szabo.
3870 * data/yacc.c (yyparse): strlen -> yystrlen.
3871
3872 2005-05-30 Akim Demaille <akim@epita.fr>
3873
3874 * data/lalr1.cc (_): New.
3875 Translate the various messages.
3876
3877 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3878
3879 Fix infringement on user name space reported by Bruno Haible.
3880 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
3881 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
3882 the user's name space.
3883 (alloca): Include <stdlib.h> to get it, if it's not built in.
3884 (YYMALLOC, YYFREE): Define only if needed.
3885 (malloc, free): Declare, but only if needed, as this infringes on
3886 the user name space.
3887
3888 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3889
3890 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
3891 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
3892 with %d format.
3893 * lib/ebitset.c (min, max): Undef before defining.
3894 * lib/vbitset.c (min, max): Likewise.
3895 * lib/subpipe.c (create_subpipe): Save local variables in case
3896 vfork clobbers them.
3897
3898 2005-05-24 Bruno Haible <bruno@clisp.org>
3899
3900 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
3901 error message syntax used by gcc-4.0.
3902
3903 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
3904
3905 * README: Mention m4 1.4.3. Remove obsolete advice about
3906 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
3907
3908 * bootstrap: Remove workaround for problem I encountered with
3909 gettext 0.14.1; it seems to be fixed now.
3910
3911 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
3912
3913 * NEWS: Version 2.0a.
3914
3915 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
3916 the previous change.
3917
3918 Various maintainer cleanups.
3919 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
3920 conftest*, for benefit of CVS commands run at the same time as
3921 "configure". Add build-aux, since "bootstrap" now creates it and
3922 its subfiles.
3923 * Makefile.cfg (move_if_change): Remove.
3924 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
3925 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
3926 (po_repo, do-po-update, po-update, wget_files, get-targets):
3927 (config.guess-url_prefix, config.sub-url_prefix):
3928 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
3929 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
3930 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
3931 Remove.
3932 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
3933 this is now the recommended name.
3934 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
3935 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
3936 ylwrap. These files now go into build-aux.
3937 * config/move-if-change: Remove.
3938 * config/prev-version.txt: Bump from 1.75 to 2.0.
3939
3940 * bootstrap: Add stdio-safer, unistd-safer modules.
3941 Remove m4/glibc2.m4 (introduced by latest gnulib, but
3942 we don't need it).
3943 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
3944 fopen-safer.c, stdio-safer.h, unistd-safer.h.
3945 * lib/subpipe.c: Include "unistd-safer.h".
3946 (create_subpipe): Make sure all the newly-created
3947 file descriptors are > 2, so that diagnostics don't
3948 get sent down them (which might cause Bison to hang, in theory).
3949 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
3950 * src/files.c (xfopen): Use fopen_safer, not fopen.
3951
3952 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
3953 yesterday's yacc.c fix.
3954
3955 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
3956
3957 * data/glr.c, data/lalr1.cc: Update copyright date.
3958
3959 Fix a destructor bug reported by Wolfgang Spraul in
3960 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
3961 * data/yacc.c (yyabortlab): Don't call destructor, and
3962 don't set yychar to EMPTY.
3963 (yyoverflowlab): Don't call destructor.
3964 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
3965 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
3966 since we no longer output the message "discarding lookahead token
3967 end of input ()".
3968
3969 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3970
3971 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
3972 fix a small glitch in debugging output.
3973 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
3974 after YY_SYMBOL_PRINT where needed.
3975
3976 (struct yyGLRState): Add some comments.
3977 (struct yySemanticOption): Add some comments.
3978 (union yyGLRStackItem): Add comment.
3979
3980 (yymergeOptionSets): Correct this to properly perform the union,
3981 avoiding infinite reported by Michael Rosien.
3982 Update comment.
3983
3984 * tests/glr-regression.at: Add test for GLR merging error reported
3985 by M. Rosien.
3986

4024
4025 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
4026
4027 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
4028 Problem reported by Ralf Menzel.
4029
4030 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4031
4032 * tests/actions.at: Test that stack overflow invokes destructors.
4033 From Marcus Holland-Moritz.
4034 * data/yacc.c (yyerrlab): Move the code that destroys the stack
4035 from here....
4036 (yyreturn): to here. That way, destructors are called properly
4037 even if the stack overflows, or the user calls YYACCEPT or
4038 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
4039 (yyoverflowlab): Destroy the lookahead.
4040
4041 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
4042
4043 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
4044
4045 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
4046
4047 * NEWS: Bison-generated C parsers no longer quote literal strings
4048 associated with tokens.
4049 * src/output.c (prepare_symbols): Don't escape strings,
4050 since users don't want to see C escapes.
4051 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
4052 in diagnostics.
4053 * tests/input.at (Torturing the Scanner): Likewise.
4054 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
4055
4056 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
4057
4058 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
4059 the data size is known to be too small and we can't increase it.
4060 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
4061
4062 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
4063
4064 * src/parse-gram.y: Include quotearg.h.
4065 (string_as_id): Quote $1 before using it as a key, since the
4066 lexer no longer quotes it for us.
4067 (string_content): Don't strip quotes, since lexer no longer
4068 quotes it for us.
4069 * src/scan-gram.l: Include quotearg.h.
4070 ("\""): Omit quote.
4071 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
4072 a key, since the rest of the lexer doesn't quote it.
4073 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
4074 * tests/regression.at (Token definitions): Check for backslashes
4075 in token strings.
4076
4077 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
4078 (YYSIZE_T): Define to unsigned long int when using an older compiler.
4079 (yyparse): Revamp code to generate long syntax error message, to
4080 make it easier to translate, and to avoid problems with arithmetic
4081 overflow. Change "virtual memory" to "memory" in diagnostic, since
4082 we don't know whether the memory is virtual.
4083
4084 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4085
4086 * NEWS: Bison-generated C parsers now use the _ macro to
4087 translate strings.
4088 * data/yacc.c (_) [!defined _]: New macro.
4089 All English strings wrapped inside this macro.
4090 * doc/bison.texinfo (Bison Parser): Document _.
4091 * po/POTFILES.in: Include src/parse-gram.c, since it now
4092 includes translateable strings that parse-gram.y doesn't.
4093
4094 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
4095
4096 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
4097 reverting the 2004-10-11 change to this function.
4098 (symbol_check_alias_consistency): Don't call symbol_type_set
4099 if the type name is already correct.
4100 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
4101
4102 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
4103
4104 * tests/regression.at (Token definitions): Don't use a token named
4105 c, as that generates a "#define c ..." that runs afoul of buggy
4106 stdlib.h that uses the identifier c as a member of struct
4107 drand48_data. Problem reported by Horst Wente.
4108
4109 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
4110
4111 * bootstrap: Change translation URL from
4112 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
4113 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
4114 redirection glitches. Problem reported by twlevo@xs4all.nl.
4115
4116 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
4117
4118 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
4119 after operands; POSIX says this isn't portable for the c99 command.
4120
4121 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
4122
4123 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
4124 immediately if a data overrun has occurred; this may help us track
4125 down what may be a spurious failure on MacOS.
4126
4127 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
4128
4129 Respond to problems reported by twlevo@xs4all.nl.
4130
4131 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
4132
4133 * src/vcg.h: Comment fix.
4134 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
4135 (G_CMAX): Change to -1 instead of INT_MAX.
4136
4137 * data/yacc.c (yyparse): Omit spaces before #line.
4138
4139 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
4140
4141 * src/tables.c (state_number_to_vector_number): Put it inside an
4142 "#if 0", since it's not currently used. Problem reported by
4143 Roland McGrath.
4144
4145 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
4146
4147 * src/output.c (escaped_output): Renamed from
4148 escaped_file_name_output, since we now use it for symbol tags as
4149 well. All uses changed.
4150 (symbol_destructors_output, symbol_printers_output):
4151 Escape symbol tags too.
4152 Problem reported by Matyas Forstner in
4153 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
4154
4155 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
4156 not needed.
4157 * src/output.c (user_actions_output, token_definitions_output,
4158 symbol_destructors_output, symbol_printers_output): Likewise.
4159 * src/reader.c (prologue_augment): Likewise.
4160 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
4161
4162 * src/vcg.c (output_edge): Don't quote linestyle arg.
4163 Problem reported by twlevo@xs4all.nl.
4164
4165 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
4166
4167 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
4168 example, reported by Derek M Jones. Also, make the example even
4169 more outrageous, to better illustrate how bad the problem is.
4170
4171 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
4172
4173 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
4174 putsym. Typo reported by Sebastian Piping.
4175
4176 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4177
4178 * doc/bison.texinfo (Language and Grammar): some -> same
4179 (Epilogue): int he -> in the
4180 Typos reported by Sebastian Piping via Justin Pence.
4181
4182 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4183
4184 * tests/glr-regression.at (Improper handling of embedded actions
4185 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
4186 embedded actions and $-N in GLR parsers", work around an Autoconf bug
4187 with dollar signs in test names.
4188 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
4189 for a similar reason.
4190
4191 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4192
4193 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
4194 wants to redefine G_VIEW.
4195
4196 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
4197
4198 * src/vcg.c (get_view_str): Remove case for normal_view.
4199 Problem reported by twlevo@xs4all.nl.
4200
4201 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
4202
4203 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
4204 Problem reported by twlevo@xs4all.nl.
4205
4206 * doc/bison.texinfo: Change @dircategory from "GNU programming
4207 tools" to "Software development". Requested by Richard Stallman
4208 via Karl Berry.
4209
4210 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
4211
4212 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
4213 Problem reported by twlevo@xs4all.nl.
4214
4215 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4216
4217 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
4218 keyword; it's not needed with modern compilers, and it doesn't
4219 affect correctness with older compilers. Suggested by
4220 twlevo@xs4all.nl.
4221
4222 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
4223
4224 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
4225 gcc -Wswitch-default.
4226 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
4227 * data/yacc.c (yyparse): Likewise.
4228
4229 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
4230
4231 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
4232 already. Let config.h define any nonstandard values.
4233
4234 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
4235
4236 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
4237 for the benefit of slower hosts. Problem reported by
4238 Nelson H. F. Beebe.
4239
4240 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
4241
4242 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
4243 being defined and not used.
4244 * data/lalr1.cc (yyparse): Likewise.
4245 Use "if (false)" rather than "if (0)".
4246
4247 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
4248
4249 * TODO: Mention that we should allow NUL bytes in tokens.
4250
4251 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
4252
4253 * src/scan-skel.l (<<EOF>>): Don't close standard output.
4254 Problem reported by Hans Aberg.
4255
4256 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
4257
4258 * src/getargs.c (version): Happy new year; update overall
4259 program copyright date from 2004 to 2005.
4260
4261 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
4262 Problem reported by Hans Aberg.
4263 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
4264 (Output file names.): Add a test for the case when standard output
4265 is closed.
4266
4267 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
4268
4269 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
4270 to fix an oversight in the Bison 2.0 manual.
4271
4272 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
4273
4274 * NEWS: Version 2.0. Reformat the existing news items since
4275 1.875, so that related items are grouped together.
4276 * configure.ac (AC_INIT): Bump version to 2.0.
4277 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
4278
4279 * tests/torture.at (Exploding the Stack Size with Alloca): Set
4280 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
4281 otherwise, we're not testing alloca. Unfortunately there's no
4282 simple way to consult HAVE_ALLOCA here.
4283
4284 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
4285 for yymsg, too.
4286
4287 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
4288 hand. This avoids a warning about comparing int to size_t when
4289 GCC warnings are enabled.
4290
4291 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
4292
4293 * NEWS: Bison-generated parsers no longer default to using the
4294 alloca function (when available) to extend the parser stack, due
4295 to widespread problems in unchecked stack-overflow detection.
4296 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
4297 responsibility to set it to a positive value. This lets the user
4298 specify a value that is not a preprocessor constant.
4299 * data/yacc.c (YYMAXDEPTH): Likewise.
4300 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
4301 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
4302 to be a compile-time constant. However, explain the constraints on it.
4303 Also, explain the constraints on YYINITDEPTH.
4304 (Table of Symbols): Explain that alloca is no longer the default.
4305 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
4306 to 1.
4307
4308 * doc/bison.texinfo (Location Default Action): Mention that n must
4309 be zero when k is zero. Suggested by Frank Heckenbach.
4310
4311 2004-12-22 Akim Demaille <akim@epita.fr>
4312
4313 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
4314 (parser::state_type, parser::semantic_type, parser::location_type):
4315 Private, not public.
4316 (parser::parse): Return ints, not bool.
4317 Returning a bool introduces a problem: 0 corresponds to false, and
4318 it seems weird to return false on success. Returning true changes
4319 the conventions for yyparse.
4320 Alternatively we could return void and send an exception.
4321 There is no clear consensus (yet?).
4322 (state_stack, semantic_stack, location_stack): Rename as...
4323 (state_stack_type, semantic_stack_type, location_stack_type): these.
4324 Private, not public.
4325 * tests/c++.at: New.
4326 * tests/testsuite.at, tests/Makefile.am: Adjust.
4327
4328 2004-12-21 Akim Demaille <akim@epita.fr>
4329
4330 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
4331
4332 2004-12-21 Akim Demaille <akim@epita.fr>
4333
4334 Don't impose std::string for filenames.
4335
4336 * data/lalr1.cc (b4_filename_type): New.
4337 (position::filename): Use it.
4338 (parser.hh): Move the inclusion of stack.hh and location.hh below
4339 the user code, so that needed headers for the filename type can be
4340 included first.
4341 Forward declare them before the user code.
4342 * tests/Makefile.am (check-local, installcheck-local): Pass
4343 TESTSUITEFLAGS to the TESTSUITE.
4344
4345 2004-12-20 Akim Demaille <akim@epita.fr>
4346
4347 Use more STL like names: my_class instead of MyClass.
4348
4349 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
4350 (SemanticStack, SemanticType, StateStack, StateType)
4351 (TokenNumberType, Stack, Slice, Traits, Parser::location)
4352 (Parser::value): Rename as...
4353 (location_stack, location_type, rhs_number_type, semantic_stack)
4354 (semantic_type, state_stack, state_type, token_number_type, stack)
4355 (slice, traits, parser::yylloc, parser::yylval): these.
4356
4357 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
4358
4359 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
4360
4361 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
4362 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4363
4364 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
4365
4366 Remove uses of 'short int' and 'unsigned short int'. This raises
4367 some arbitrary limits. It uses more memory but nowadays that's
4368 not much of an issue.
4369
4370 This change does not affect the generated parsers; that's a different
4371 task, as some users will want to conserve memory there.
4372
4373 Ideally we should use size_t to represent all object counts, and
4374 something like ptrdiff_t to represent signed differences of object
4375 counts; but that will require more code-cleanup than I have the
4376 time to do right now.
4377
4378 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
4379 Use size_t, not int or short int, to count objects.
4380 * src/closure.c (nritemset, closure): Likewise.
4381 * src/closure.h (nritemset, closure): Likewise.
4382 * src/nullable.c (nullable_compute): Likewise.
4383 * src/print.c (print_core): Likewise.
4384 * src/print_graph.c (print_core): Likewise.
4385 * src/state.c (state_compare, state_hash): Likewise.
4386 * src/state.h (struct state): Likewise.
4387 * src/tables.c (default_goto, goto_actions): Likewise.
4388
4389 * src/gram.h (rule_number, rule): Use int, not short int.
4390 * src/output.c (prepare_rules): Likewise.
4391 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
4392 errs, reductions): Likewise.
4393 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
4394 Likewise.
4395 * src/tables.c (vector_number, tally, action_number,
4396 ACTION_NUMBER_MINIMUM): Likewise.
4397 * src/output.c (muscle_insert_short_int_table): Remove.
4398
4399 2004-12-17 Akim Demaille <akim@epita.fr>
4400
4401 * data/lalr1.cc: Extensive Doxygenation.
4402 (error_): Rename as...
4403 (error): this, since it is visible to the user.
4404 Adjust callers.
4405 (Parser::message): Now an automatic variable from...
4406 (Parser::yyreport_syntax_error_): here.
4407 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
4408 Parser::error.
4409 * tests/input.at: Escape $.
4410
4411 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
4412
4413 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
4414 Parenthesize rhs to avoid obscure problems with mistakes like
4415 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
4416 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
4417 b4_rhs_location): Likewise.
4418 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
4419 b4_rhs_location): Likewise.
4420
4421 2004-12-16 Akim Demaille <akim@epita.fr>
4422
4423 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
4424 yacc.c: be sure to stay within yycheck_.
4425 * tests/actions.at: Re-enable C++ tests.
4426
4427 2004-12-16 Akim Demaille <akim@epita.fr>
4428
4429 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
4430 real.
4431
4432 2004-12-16 Akim Demaille <akim@epita.fr>
4433
4434 Use #define to handle the %name-prefix.
4435
4436 * data/glr.c, data/yacc.c: Comment changes.
4437 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
4438 so that one can refer to yylex in the parser file, and have it
4439 renamed, as is the case with other skeletons.
4440
4441 2004-12-16 Akim Demaille <akim@epita.fr>
4442
4443 Move lalr1.cc internals into yy*.

4461 these.
4462
4463 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
4464
4465 Fix some problems reported by twlevo at xs4all.
4466 * src/symtab.c (symbol_new): Report an error if the input grammar
4467 contains too many symbols. This is better than calling abort() later.
4468 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
4469 (struct node, struct graph):
4470 Rename member expand to stretch. All uses changed.
4471 (struct graph): Remove member layoutalgorithm. All uses removed.
4472 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
4473 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
4474 All uses changed.
4475 (N_STRETCH): Rename from N_EXPAND. All uses changed.
4476
4477 2004-12-15 Akim Demaille <akim@epita.fr>

4480 Add more Doxygen comments.
4481 (symprint_, stack_print_, reduce_print_, destruct_, pop)
4482 (report_syntax_error_, translate_): Rename as...
4483 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
4484 (yypop_, yyreport_syntax_error_, yytranslate_): this.
4485
4486 2004-12-15 Akim Demaille <akim@epita.fr>
4487
4488 * data/lalr1.cc (lex_): Rename as...
4489 (yylex_): this.
4490 Move the trace here.
4491 Take the %name-prefix into account.
4492 Reported by Alexandre Duret-Lutz.
4493
4494 2004-12-15 Akim Demaille <akim@epita.fr>
4495
4496 Simplify the C++ parser constructor.
4497
4498 * data/lalr1.cc (debug_): Rename as...
4499 (yydebug_): so that the parser's internals are always in the yy*
4500 pseudo namespace.
4501 Adjust uses.
4502 (b4_parse_param_decl): Remove the leading comma as it is now only
4503 called as unique argument list.
4504 (Parser::Parser): Remove the constructor accepting a location and
4505 an initial debugging level.
4506 Remove from the other ctor the argument for the debugging level.
4507 (debug_level_type, debug_level, set_debug_level): New.
4508
4509 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
4510 constructor calls.
4511
4512 2004-12-15 Akim Demaille <akim@epita.fr>
4513
4514 Remove b4_root related material: failure experiment
4515 (which goal was to allow to derive from a class).
4516
4517 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
4518 definitions and uses.
4519
4520 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
4521
4522 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
4523 not 2, since it's not portable to subtract 1 from the start of an
4524 array. The new item 0 is never set or used. All uses changed.
4525
4526 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
4527 the default definition of YYLLOC_DEFAULT. Problem reported
4528 by Frank Heckenbach.
4529
4530 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
4531
4532 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
4533 the normal case and one for the error case. Just use the
4534 first one uniformly. Problem reported by Frank Heckenbach.
4535 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
4536 use exactly the same macro in both places.
4537 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
4538 so that the normal-case YYRHSLOC works for the error case too.
4539 All uses changed.
4540 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
4541 (YYLLOC_DEFAULT): Use the same macro as glr.c.
4542 * doc/bison.texinfo (Location Default Action): Don't claim that
4543 we have an array of locations. Use the same macro for both glr
4544 and lalr parsers. Mention YYRHSLOC. Mention what happens when
4545 the index is 0.
4546
4547 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
4548
4549 * HACKING: Update email addresses to send announcements to.
4550
4551 * configure.ac (AC_INIT): Bump version to 1.875f.
4552
4553 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

4557
4558 * src/scan-skel.l: Include "complain.h", for "fatal".
4559
4560 * src/relation.h (relation_print, relation_digraph):
4561 Relation sizes are of type relation_node, not size_t (this is
4562 merely a doc fix, since the two types are equivalent).
4563 (relation_transpose): Relation sizes are of type relation_node,
4564 not int.
4565 * src/relation.c: Likewise.
4566 (top, infinity): Now of type relation_node, not int.
4567 (traverse, relation_transpose): Use relation_node, not int.
4568
4569 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
4570 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
4571 (yyparse): Remove unused local introduced in 2004-10-25 patch.
4572
4573 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
4574 specifying whether the test should be skipped. Use it tp
4575 specify that the [%defines %skeleton "lalr1.cc"] tests currently
4576 fail on some hosts, and should be skipped.
4577
4578 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4579
4580 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
4581 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
4582 unless otherwise specified below.
4583
4584 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
4585 to allocate kernel_base, kernel_items, kernel_size, since
4586 they needn't be initialized to 0.
4587 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
4588 * src/closure.c (new_closure): Likewise, for itemset.
4589 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
4590 * src/lalr.c (set_goto_map): Likewise, for temp_map.
4591 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
4592 (build_relations): Likewise for edge, states1, includes.
4593 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
4594 * src/reader.c (packgram): Likewise, for ritem, rules.

4596 * src/relation.c (relation_digraph): Likewise for VERTICES.
4597 (relation_transpose): Likewise for new_R, end_R.
4598 * src/symtab.c (symbols_token_translations_init): Likewise for
4599 token_translations.
4600 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
4601 (token_actions): Likewise for yydefact, actrow, conflrow,
4602 conflict_list.
4603 (save_column): Likewise for froms[symno], tos[symno].
4604 (goto_actions): Likewise for state_count.
4605 (pack_table): Likewise for base, pos, check.
4606 (tables_generate): Likewise for width.
4607
4608 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
4609 for initial core. Just have a separate core, so we needn't worry
4610 about whether kernel_size and kernel_base are initialized.
4611
4612 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
4613 kernel_size, kernel_items): Remove unnecessary initialization.
4614 * src/conflicts.c (conflicts): Likewise.
4615 * src/derives.c (derives): Likewise.
4616 * src/muscle_tablc (muscle_insert): Likewise.
4617 * src/relation.c (relation_digraph): Likewise.
4618 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
4619 conflrow, conflict_table, conflict_list, table, check):
4620 Likewise.
4621
4622 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
4623 This is because all callers pass unsigned int.
4624 * src/closure.h (new_closure): Likewise.
4625
4626 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
4627 (build_relations): Initialize includes[i] in all cases.
4628 * src/reader.c (packgram): Always initialize rules[ruleno].prec
4629 and rules[ruleno].precsym. Initialize members in order.
4630 * src/relation.c (relation_transpose): Always initialize new_R[i]
4631 and end_R[i].
4632 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
4633
4634 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
4635 conflict_list[0] was always 0, but now it isn't initialized.
4636
4637 * src/table.c (table_grow): When conflict_table grew, the grown
4638 area wasn't cleared. Fix this.
4639
4640 * lib/.cvsignore: Add strdup.c, strdup.h.
4641 * m4/.cvsignore: Add strdup.m4.
4642
4643 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
4644
4645 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
4646 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
4647 GOTO_NUMBER_MAXIMUM, since we occasionally compute
4648 ngotos + 1 without checking for overflow.
4649 (build_relations): Use END_NODE, not -1, to denote end of edges.
4650 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
4651 build_relations): Use goto_number, not int, for goto numbers.
4652 * src/tables.c (save_column, default_goto): Likewise.
4653
4654 2004-11-23 Akim Demaille <akim@epita.fr>
4655
4656 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
4657 of #defining from yystype.
4658 Don't typedef yystype, C++ does not need it.
4659 This lets it possible to forward declare it as union.
4660
4661 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
4662
4663 * bootstrap (gnulib_modules): Add extensions.
4664 Problem reported by Jim Meyering.
4665
4666 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
4667
4668 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
4669 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
4670 src/system.h, src/tables.c: XFREE -> free, to accommodate
4671 recent change to gnulib xalloc.h.
4672 Problem reported by Jim Meyering.
4673
4674 2004-11-17 Akim Demaille <akim@epita.fr>
4675
4676 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
4677
4678 2004-11-17 Akim Demaille <akim@epita.fr>,
4679 Alexandre Duret-Lutz <adl@gnu.org>
4680
4681 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
4682 changes.
4683 (YYCDEBUG): Adjust.
4684 Use it instead of cdebug_.
4685 (Parser::debug_stream, Parser::set_debug_stream): New.
4686 (Parser::symprint_): Define cdebug_ for temporary backward
4687 compatibility.
4688 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
4689 debug_stream ().
4690
4691 2004-11-17 Akim Demaille <akim@epita.fr>
4692
4693 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
4694 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
4695 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
4696 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
4697
4698 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
4699
4700 * data/glr.c (yyloc_default): Remove; not used.
4701 Problem reported by Frank Heckenbach.
4702
4703 2004-10-25 Akim Demaille <akim@epita.fr>
4704
4705 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
4706 Introduce another definition to address simple location arrays.
4707 (yyGLRStack): New member: yyerror_range.
4708 (yyrecoverSyntaxError, yyparse): Update it.
4709 (yyrecoverSyntaxError): Use it when shifting the error token to
4710 have an accurate range, equivalent to the one computed by both
4711 yacc.c and lalr1.cc.
4712 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
4713 that column numbers start at column 0, as per GNU Coding
4714 Standards, the others tests, and the doc.
4715 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
4716 Adjust to the above change (first column is 0).
4717 And adjust the location of the "<error>", now covering the whole
4718 line.
4719
4720 2004-10-22 Akim Demaille <akim@epita.fr>
4721 and Paul Eggert <eggert@cs.ucla.edu>
4722
4723 Remove some arbitrary limits on goto numbers and relations.
4724 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
4725 initial values, since they're never used.
4726 (set_goto_map): ngotos is now unsigned, so test for overflow
4727 by seeing whether it wraps around to zero.
4728 * src/lalr.h (goto_number): Now size_t, not short int.
4729 (GOTO_NUMBER_MAXIMUM): Remove.
4730 * src/relation.c (relation_print, traverse, relation_transpose):
4731 Check for END_NODE rather than looking at sign.
4732 * src/relation.h (END_NODE): New macro.
4733 (relation_node): Now size_t, not short int.
4734
4735 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
4736
4737 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
4738 keyword, not an identifier. Problem reported by Baron Schwartz in
4739 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
4740
4741 2004-10-11 Akim Demaille <akim@epita.fr>
4742
4743 * src/symtab.c (symbol_check_alias_consistency): Also check
4744 type names, destructors, and printers.
4745 Reported by Alexandre Duret-Lutz.
4746 Recode the handling of associativity and precedence in terms
4747 of symbol_precedence_set.
4748 Accept no redeclaration at all, not even equal to the previous
4749 value.
4750 (redeclaration): New.
4751 Use it to factor redeclaration complaints.
4752 (symbol_make_alias): Don't set the type of the alias, let
4753 symbol_check_alias_consistency do it as for other features.
4754 * src/symtab.h (symbol): Add new member prec_location, and
4755 type_location.
4756 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
4757 * tests/input.at (Incompatible Aliases): New.
4758
4759 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
4760
4761 .cvsignore fixes to accommodate gnulib changes,
4762 and the practice of naming build directories "_build".
4763 * .cvsignore: Add "_*". Sort.
4764 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
4765 * m4/.cvsignore: Add "*_gl.m4".
4766
4767 2004-10-06 Akim Demaille <akim@epita.fr>
4768
4769 * src/parse-gram.y (add_param): Fix the truncation of trailing
4770 spaces.
4771
4772 2004-10-05 Akim Demaille <akim@epita.fr>
4773
4774 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4775 whether the reducion was empty or not. This leaves room to
4776 improve the use of YYLLOC_DEFAULT in such a case.
4777 lalr1.cc is still experimental, so changing this is acceptable.
4778 And finally, there are probably not many users who changed the
4779 handling of locations in GLR, so changing is admissible too.
4780
4781 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
4782 empty reduction, set @$ to an empty location ending the previously
4783 stacked symbol.
4784 Adjust uses to make sure the code is triggered on empty
4785 reductions.
4786 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
4787 expected output: empty reductions have empty locations.
4788
4789 2004-09-29 Akim Demaille <akim@epita.fr>
4790
4791 * data/lalr1.cc: Move towards a more standard C++ coding style
4792 for templates: Class < T > -> Class<T>.
4793
4794 2004-09-29 Akim Demaille <akim@epita.fr>
4795
4796 * data/lalr1.cc: Reinstall the former ctor, for sake of
4797 compatibility, but warn it will be removed.
4798 Move towards a more standard C++ coding style (i.e., type *var ->
4799 type* var).
4800
4801 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
4802
4803 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
4804 since it's less likely to work if NULs are involved in the future.
4805
4806 2004-09-27 Akim Demaille <akim@epita.fr>
4807
4808 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
4809
4810 2004-09-27 Akim Demaille <akim@epita.fr>
4811
4812 * data/lalr1.cc (b4_parse_param_decl_1): New.
4813 (b4_parse_param_decl): Use it to have different names between attribute
4814 and argument names.
4815 (b4_cc_constructor_call): Likewise.
4816
4817 2004-09-24 Akim Demaille <akim@epita.fr>
4818
4819 * src/parse-gram.y (add_param): Strip the leading and trailing
4820 blanks from a formal argument declaration.
4821 (YY_LOCATION_PRINT): New.
4822
4823 2004-09-24 Akim Demaille <akim@epita.fr>
4824
4825 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
4826 after the location.
4827
4828 2004-09-24 Akim Demaille <akim@epita.fr>
4829
4830 * doc/bison.texinfo (Table of Symbols): Sort.
4831
4832 2004-09-21 Akim Demaille <akim@epita.fr>
4833
4834 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
4835 the useless parentheses.
4836 Suggested by Paul Eggert.
4837
4838 2004-09-20 Akim Demaille <akim@epita.fr>
4839
4840 Let the initial-action act on the look-ahead, and use it for the
4841 "initial push" (corresponding to an hypothetical beginning-of-file).
4842 And let lalr1.cc honor %initial-action.
4843
4844 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
4845 example.
4846 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
4847 (Parser::Parser): Remove the ctor that used to initialize it.
4848 (Parser::parse): Like in the other skeletons, issue the "starting
4849 parse" message before any action.
4850 Honor %initial-action.
4851 Initialize the stacks with the lookahead.
4852 * data/yacc.c: Let $$ and @$ in %initial-action designate the
4853 look-ahead.
4854 Push them in the stacks.
4855 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
4856
4857 2004-09-20 Akim Demaille <akim@epita.fr>
4858
4859 * doc/bison.texinfo (Initial Action Decl): New.
4860
4861 2004-09-20 Akim Demaille <akim@epita.fr>
4862
4863 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
4864 clearer criterion to define it.
4865 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
4866 When reducing on an empty RHS, use the latest stacked location as
4867 location.
4868 yylloc is not always available.
4869 * data/glr.c: Likewise.
4870 Also, honor initial-actions.
4871
4872 2004-09-20 Akim Demaille <akim@epita.fr>
4873
4874 * data/yacc.c (YY_LOCATION_PRINT): New.
4875 Define when we know YYLTYPE's structure, i.e., when the default
4876 YYLLOC_DEFAULT is used.
4877 * data/c.m4 (b4_yysymprint_generate): Use it.
4878 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
4879 value of the result.
4880 (error_start_): Replace with...
4881 (error_range_): this location array.
4882 This allows to replace code relying on the implementation of
4883 locations by portable code.
4884 * data/yacc.c (yylerrsp): Replace with...
4885 (yyerror_range): this.
4886 Every time a token is popped, update yyerror_range[0], to have an
4887 accurate location for the error token.
4888 * data/glr.c (YY_LOCATION_PRINT): New.
4889 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
4890 deference a pointer.
4891 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
4892 report the location in %printers.
4893
4894 * src/scan-skel.l: Instead of abort, report error messages to ease
4895 understanding skeleton scanning failures.
4896
4897 2004-09-16 Akim Demaille <akim@epita.fr>
4898
4899 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
4900 (iterator, const_iterator): these, to be more in the C++ spirit.
4901 Also, return reverse iterators so that when displaying the stack
4902 we display its bottom first.
4903 (Parser::stack_print_, Parser::reduce_print_): Match the messages
4904 from yacc.c.
4905 We should probably use vector here though.
4906
4907 2004-09-16 Akim Demaille <akim@epita.fr>
4908
4909 Have more complete shift traces.
4910
4911 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
4912 to report Shifts instead of ad hoc YYDPRINTF invocations,
4913 including for the error token.
4914 * data/lalr1.cc (symprint_): Output the location.
4915 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
4916 output the location within the %printer.
4917 Activate GLR tests, at least to make sure they compile properly.
4918 They still don't pass though.
4919 * tests/calc.at: Adjust expect verbose output, since now "Entering
4920 state..." is on a different line than the "Shifting" message.
4921
4922 2004-09-08 Akim Demaille <akim@epita.fr>
4923
4924 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
4925 Bison directive from the Bison file to the invocation of this
4926 macro, so that these directives are passed to
4927 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
4928 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
4929 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
4930 the extra Bison directives instead of the whole series.
4931 Change the grammar so that there are recoverable errors, and
4932 unrecoverable errors. Now we can have the parser give up before
4933 consuming the whole input. As a result we now can observe that
4934 the lookahead is freed when needed.
4935 Change the parser source to parse argv[1] instead of a hard coded
4936 string.
4937 Simplify yylex, and give a value and location to EOF.
4938 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
4939 passed directives already coded in the file.
4940 Add some tests to check the location of "error".
4941 For some tests, the C++ parser is correct, and not yacc.c.
4942 For other tests, they provide different, but unsatisfying, values,
4943 so keep the C++ value so that at least one parser is "correct"
4944 according to the test suite.
4945 (Actions after errors): Remove, this is subsumed by the
4946 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
4947
4948 2004-09-06 Akim Demaille <akim@epita.fr>
4949
4950 * data/lalr1.cc: Adjust the indentation of the labels.
4951 (Parser::pop): New.
4952 Use it.
4953
4954 2004-09-06 Akim Demaille <akim@epita.fr>
4955
4956 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
4957 argument, an informative message.
4958 Call YY_SYMBOL_PRINT.
4959 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
4960 * data/lalr1.cc (destruct_): Likewise.
4961 In addition, no longer depend on b4_yysymprint_generate and
4962 b4_yydestruct_generate to generate these functions, do it "by
4963 hand".
4964
4965 2004-09-03 Akim Demaille <akim@epita.fr>
4966
4967 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
4968 invoked, yydestruct the lookahead.
4969 * tests/calc.at (Calculator $1): Update the expected lengths of
4970 traces: there is an added line for the discarded lookahead.
4971 * doc/bison.texinfo (Destructor Decl): Some rewording.
4972 Define "discarded" symbols.
4973
4974 2004-09-02 Akim Demaille <akim@epita.fr>
4975
4976 * data/lalr1.cc (translate_, destruct_): No reason to be static.
4977
4978 2004-09-02 Akim Demaille <akim@epita.fr>
4979
4980 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
4981 (YYDSYMPRINTF): Rename as...
4982 (YY_SYMBOL_PRINT): this.
4983 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
4984 two.
4985 Use it instead of direct symprint_ calls.
4986 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
4987 one.
4988
4989 2004-09-02 Akim Demaille <akim@epita.fr>
4990
4991 * data/lalr1.cc (b4_yysymprint_generate): New.
4992 (symprint_): New member function, defined when YYDEBUG.
4993 Use it consistently instead of token/nterm debugging output by
4994 hand.
4995 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
4996 %printer calls to use cdebug_ when using lalr1.cc.
4997
4998 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
4999
5000 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
5001 with #ifdef YYDEBUG.
5002
5003 2004-08-26 Akim Demaille <akim@epita.fr>
5004
5005 * doc/bison.texinfo (Implementing Loops): Rename as...
5006 (Implementing Gotos/Loops): this.
5007
5008 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
5009
5010 Adjust to latest gnulib.
5011 * bootstrap (gnulib_modules): Add xalloc-die.
5012 Set LC_ALL=C so that file names sort consistently.
5013 Prefer the gnulib copies of gettext.m4, glibc21.m4,
5014 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
5015 uintmax_t.m4, ulonglong.m4.
5016 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
5017 po.m4 since we are now using _gl.m4 instead.
5018
5019 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
5020
5021 * src/scan-action.l: Remove. Scanning of semantic actions is
5022 handled in scan-gram.l.
5023
5024 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
5025
5026 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
5027
5028 * src/location.h (struct): The file member is a uniqstr.
5029 (equal_boundaries): Use UNIQSTR_EQ for comparison.
5030
5031 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
5032
5033 Fix bug with non-%union parsers that have printers or destructors,
5034 which led to a Bison core dump. Reported by Peter Fales in
5035 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
5036
5037 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
5038 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
5039 not to our own type.
5040 * src/output.c (symbol_destructors_output, symbol_printers_output):
5041 Don't assume %union.
5042 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
5043 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
5044 UNION-FLAG. All callers changed.
5045 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
5046 Use type char, not unsigned int, when declaring an array of char;
5047 this lets us remove a cast.
5048 (Printers and Destructors): Add non-%union test cases.
5049
5050 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
5051
5052 * doc/bison.texinfo: Minor editorial changes, mostly to the new
5053 GLR writeups. E.g., avoid frenchspacing and the future tense,
5054 change "lookahead" to "look-ahead", and change "wrt" to "with
5055 respect to".
5056
5057 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5058
5059 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
5060 New sections, split off from the GLR Parsers section. Put the new
5061 Simple GLR Parser near the start of the GLR section, for clarity.
5062 Rewrite connective text.
5063
5064 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

5068 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
5069
5070 * NEWS, TODO, doc/bison.texinfo:
5071 Use "look-ahead" instead of "lookahead", to be consistent.
5072 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
5073 while we're fixing "look-ahead".
5074 * src/conflicts.c (shift_set): Renamed from shiftset.
5075 (look_ahead_set): Renamed from lookaheadset.
5076 * src/print.c: Likewise.

5096
5097 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
5098
5099 Don't assume the C++ compiler takes the same arguments as the C compiler
5100 (trivial change).
5101 * configure.ac (O0CXXFLAGS): New var.
5102 * tests/atlocal.in (CXXFLAGS): Use it.
5103
5104 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
5105
5106 Fix some "make check" problems with C++ reported by
5107 Albert Chin-A-Young for Tru64 C++ in this thread:
5108 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
5109
5110 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
5111 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5112 Output to a .cc file for C++, not to a .c file.
5113 * tests/calc.at (AT_CHECK_CALC): Likewise.
5114 * tests/regression.at (AT_CHECK_DANCER): Likewise.
5115 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
5116
5117 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
5118
5119 * tests/calc.at, tests/actions.at: Workaround for SGI
5120 C++ compiler. (trivial change)
5121
5122 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
5123
5124 Spent a few hours checking out which prerequisite versions the
5125 current sources actually require. I went all the way back to
5126 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
5127 a seemingly endless set of combinations of versions more recent
5128 than that. The bottom line is that the current sources require
5129 fairly recent versions of the build tools, and it'll be some work
5130 to change this.
5131 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
5132 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
5133 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
5134 Add comments explaining why those particular versions are
5135 currently needed.
5136
5137 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
5138 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
5139 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
5140
5141 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
5142 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
5143
5144 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5145
5146 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
5147 0.11.5. Suggested by Bruno Haible.
5148 * bootstrap: Remove gettext version checking.
5149
5150 * doc/bison.texinfo (Decl Summary): Also mention that %union
5151 can depend on prerequisite types. Problem reported by Tim
5152 Van Holder.
5153
5154 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5155
5156 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
5157 * README-alpha: Don't tell people not to package this.
5158
5159 * bootstrap: Don't assume $(...) works; use `...` instead.
5160 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
5161 gettext better.
5162
5163 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
5164 put into the -d output file, and mention what to do if YYSTYPE is
5165 defined as a macro.
5166
5167 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5168
5169 Undo change made earlier today: it caused autopoint to not bring
5170 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
5171 autopoint's.
5172
5173 * bootstrap: Check that gettext version matches what's in
5174 configure.ac. Warn users to ignore robots.txt ERROR 404.
5175 * bootstrap: Undo today's earlier change (logged below).
5176 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
5177
5178 The gettext version checking is causing more trouble than it's
5179 curing; remove it. Problem reported by Paul Hilfinger.
5180
5181 * bootstrap: Issue a warning that one can expect a message
5182 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
5183 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
5184
5185 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
5186
5187 Ensure that the C++ compiler used for testing actually works on a
5188 simple test program; if not, skip the C++-related tests. Problem
5189 reported by Vin Shelton in:
5190 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
5191
5192 * m4/cxx.m4: New file.
5193 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
5194 * tests/atlocal.in (BISON_CXX_WORKS): Add.
5195 * tests/local.at (AT_COMPILE_CXX): Use it.
5196
5197 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
5198
5199 * data/glr.c (yylloc): Output this macro even if locations are not
5200 being generated, as the GLR parser needs it even in that case.
5201 Problem reported by Troy A. Johnson
5202 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
5203
5204 * configure.ac (AC_INIT): Update to 1.875e.
5205
5206 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
5207
5208 * NEWS: Version 1.875d.
5209 * configure.ac (AC_INIT): Likewise.
5210 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
5211
5212 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
5213 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
5214 lalr1.cc runs afoul of the first, and the last two are no longer
5215 supported by GCC 3.4.0.
5216 * README: Mention GNU m4 1.4 or later; mention m4 patches.
5217 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
5218
5219 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
5220
5221 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

5225 * src/uniqstr.c (hash_uniqstr): Likewise.
5226
5227 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5228
5229 * NEWS: Unescaped newlines are no longer allowed in char & strings.
5230
5231 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
5232 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
5233 character and string literals.
5234 (unexpected_end): New function.
5235 (unexpected_eof): Use it.
5236 (unexpected_newline): New function.
5237 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
5238 actions.
5239
5240 * NEWS: Document %expect-rr.
5241
5242 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
5243 Fix typo by replacing $1 with $option.
5244 Remove more 'intl'-related files.
5245 Don't DEFUN AM_INTL_SUBDIR twice.
5246
5247 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
5248 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
5249 strtoul.c.
5250 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
5251 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
5252 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
5253 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
5254 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
5255 * src/.cvsignore: Add *.output.
5256
5257 * src/parse-gram.y: Put copyright notice inside %{ %} so it
5258 gets copied to the output file.
5259
5260 2004-04-28 Paul Eggert <eggert@twinsun.com>
5261
5262 Get files from the gnulib and po repositories, instead of relying
5263 on them being in our CVS. Upgrade to latest versions of gnulib
5264 and Automake.
5265
5266 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
5267 * bootstrap: Bootstrap from gnulib and po repositories.
5268 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
5269 * README-cvs: Document these changes. Remove version numbers from
5270 mentions of build tools, since they change so often. Mention Flex.
5271
5272 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
5273 (gl_USE_SYSTEM_EXTENSIONS): Add.
5274 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
5275 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
5276 does this for us.
5277 (AC_ISC_POSIX): Remove; we no longer support this
5278 ancient OS, as it gets in the way of latest Autoconf & gnulib.
5279 (AC_HEADER_STDC): Remove: we now assume C89 or better.
5280 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
5281 Do not check for C89 headers, except for locale.h which is used
5282 by the Yacc library and must port to K&R hosts.
5283 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
5284 Do not check for C89 functions, except for setlocale which is
5285 used by the Yacc library.
5286 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
5287 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
5288 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,
5289 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE,
5290 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
5291 AM_GNU_GETTEXT): Remove; now done by:
5292 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
5293 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
5294 for us.
5295
5296 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
5297 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
5298 Define to empty, as gnulib.mk will do the rest for us.
5299 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
5300 for us.
5301 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
5302 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
5303
5304 * src/files.c: Include gnulib's xstrndup.h.
5305
5306 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
5307 (REALLOC): Use xnrealloc, for likewise.
5308 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
5309 (strnlen, memrchr): Remove decls; functions no longer used.
5310 Include <stpcpy.h>.
5311
5312 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

5332 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
5333 Remove, as these files are now generated automatically
5334 by bootstrap or automake.
5335
5336 * po/ChangeLog: Remove: all but one entry was a duplicate
5337 of this file, and I moved that 2000-11-02 entry here.
5338
5339 * config/.cvsignore: Add Makefile, depcomp, install-sh.
5340 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

5356 * src/.cvsignore: Remove *_.c.
5357
5358
5359 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
5360 support it. (The latest stable gzip doesn't.)
5361
5362 2004-04-27 Paul Eggert <eggert@twinsun.com>
5363
5364 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
5365 case, as stos_ is now used by destructors due to the 2004-02-09
5366 change.
5367
5368 Remove more K&R C support.
5369 * lib/libiberty.y (PARAMS): Remove. All uses removed.
5370 * lib/subpipe.c (errno): Remove decl.
5371 Include <stdlib.h> unconditionally.
5372 (EXIT_FAILURE): Remove macro.
5373 * src/complain.c (vfprintf, strerror): Remove.
5374 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
5375 unconditionally.
5376 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
5377 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
5378 (strchr, strspn, memchr): Remove decls.
5379 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
5380 unconditionally. Do not declare perror.
5381 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
5382 unconditionally.
5383
5384 * src/complain.c (_): Remove useless defn, as system.h defines this.
5385
5386 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
5387 with latest obstack.h.
5388 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
5389 to procedure types, as obstack.h now does that for us.
5390 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
5391
5392 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
5393 so that this include file can stand alone.
5394 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
5395 does this now. Include subpipe.h first after config.h, to
5396 test whether it can stand alone.
5397
5398 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
5399 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
5400 unused declaration.
5401
5402 * tests/synclines.at (%union synch line): Put a dummy member in
5403 the union, because empty unions aren't allowed in C. Caught
5404 by GCC 3.4.0.
5405
5406 2004-04-13 Jim Meyering <jim@meyering.net>
5407
5408 * src/conflicts.c (conflicts_print): Correct format string typo:
5409 use `%%' to produce literal `%'. (trivial change)
5410
5411 2004-03-30 Paul Eggert <eggert@twinsun.com>
5412
5413 * src/getargs.c (version): Update copyright year to 2004.
5414
5415 * data/c.m4 (b4_int_type): Use 'short int' rather than
5416 'short', and similarly for 'long', 'unsigned', etc.
5417 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,

5471
5472 * doc/bison.texinfo: Add documentation for %expect-rr.
5473
5474 2004-03-08 Paul Eggert <eggert@gnu.org>
5475
5476 Add support for hex token numbers. Suggested by Odd Arild Olsen in
5477 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
5478
5479 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
5480 in lalr1.cc.
5481 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
5482 * src/scan-gram.l (scan_integer): New function.
5483 ({int}): Use it.
5484 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
5485 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
5486 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
5487 Say "long int", not "long", for uniformity with GNU style.
5488
5489 2004-02-25 Paul Eggert <eggert@twinsun.com>
5490
5491 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
5492 compilers. This fixes a problem with Intel's C++ compiler being
5493 chatty, reported by Guido Trentalancia in
5494 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
5495
5496 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
5497
5498 Support %destructor and merge error locations in lalr1.cc.
5499
5500 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
5501 (Parser::stos_): Define unconditionally.

5506 token which are discarded.
5507 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
5508 error_start_ when erroneous token are discarded.
5509 (Parser::parse) <yyerrlab1>: Compute the location of the error
5510 token so that it covers all the discarded tokens.
5511 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
5512 it can be called with `%skeleton "lalr1.cc"', and do that.
5513
5514 2004-02-02 Paul Eggert <eggert@twinsun.com>
5515
5516 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
5517 $(top_srcdir)/lib and ../lib. This fixes a bug reported
5518 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
5519 There's no need to mention top_builddir since Automake does that
5520 for us.
5521 (INCLUDES): Remove, as Automake says it's obsolescent.
5522 Contents migrated into AM_CPPFLAGS as described above.
5523 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
5524
5525 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5526
5527 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
5528 (yyreportSyntaxError): Handle case where lookahead token is
5529 YYEMPTY.
5530
5531 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5532
5533 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
5534 resulting parsers are compilable with C++.
5535
5536 2003-12-23 Paul Eggert <eggert@twinsun.com>
5537
5538 * config/depcomp, config/install-sh: Sync with Automake 1.8.
5539 * src/output.c (output_skeleton): Rename local var.
5540 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
5541 Bison tokens, as this runs afoul of the 2003-10-07 change that
5542 disallowed NUL bytes in character constants or string literals.
5543
5544 * tests/local.at: Require Autoconf 2.59's Autotest.
5545 * tests/testsuite.at: Don't include local.at, since we now assume
5546 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
5547 including it.
5548 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
5549 multiple inclusion warnings.
5550
5551 2003-12-02 Akim Demaille <akim@epita.fr>

5562
5563 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
5564 if testsuite doesn't exist.
5565
5566 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
5567 literals, unfortunately.
5568 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
5569 Complain about NUL bytes in character constants or string literals.
5570
5571 2003-10-05 Paul Eggert <eggert@twinsun.com>
5572
5573 * NEWS: Don't document %no-default-prec, as it's still
5574 too experimental.
5575 * doc/bison.texinfo: Document %no-default-prec only if
5576 the defaultprec flag is set. Normally it's not.
5577
5578 2003-10-04 Paul Eggert <eggert@twinsun.com>
5579
5580 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
5581 non-modifiable lvalue, instead of a modifiable one.
5582 * doc/bison.texinfo (Actions): Document that $$ can
5583 be assigned to. Do not claim that $$ and $N are
5584 array element references: user code should not rely on this.
5585
5586 2003-10-01 Paul Eggert <eggert@twinsun.com>
5587
5588 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
5589 (grammar_declaration): Use it.
5590 * src/scan-gram.l: New token %no-default-prec.
5591 * tests/conflicts.at: Revamp tests to use %no-default-prec.
5592 * NEWS, doc/bison.texinfo: Document the above.
5593
5594 2003-10-01 Akim Demaille <akim@epita.fr>
5595
5596 VCG no longer supports long_straight_phase.
5597

5599 * src/print_graph.c (print_graph): Adjust.
5600
5601 2003-09-30 Frank Heckenbach <frank@g-n-u.de>

5615 2003-09-30 Paul Eggert <eggert@twinsun.com>
5616
5617 * tests/testsuite.at: Include local.at, not input.at, fixing
5618 a typo in the 2003-08-25 patch.
5619
5620 2003-08-27 Akim Demaille <akim@epita.fr>
5621
5622 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
5623 GCC warnings.
5624
5625 2003-08-26 Akim Demaille <akim@epita.fr>
5626
5627 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
5628 "<\#" to avoid magic from Gnus when posting parts of this script.
5629
5630 2003-08-26 Akim Demaille <akim@epita.fr>
5631
5632 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
5633 (Parser::parse): here.
5634 Adjust: nerrs and errstatus is now replaced by...

5643
5644 2003-08-25 Akim Demaille <akim@epita.fr>
5645
5646 When reducing initial empty rules, Bison parser read an initial
5647 location that is not defined. This results in garbage, and that
5648 affects Bison's own parser. Therefore we need (i) to extend Bison
5649 to support a means to initialize this location, and (ii) to use
5650 this CVS Bison to fix CVS Bison's parser.
5651
5652 * src/reader.h, reader.c (epilogue_augment): Remove, replace
5653 with...
5654 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
5655 * src/parse-gram.y: Adjust.
5656 (%initial-action): New.
5657 (%error-verbose): Since we require CVS Bison, there is no reason
5658 not to use it.
5659 * src/scan-gram.l: Adjust.
5660 * src/Makefile.am (YACC): New, to make sure we use our own parser.
5661 * data/yacc.c (yyparse): Use b4_initial_action.
5662
5663 2003-08-25 Akim Demaille <akim@epita.fr>
5664
5665 * doc/bison.texinfo: Don't promote stdout for error messages.
5666
5667 2003-08-25 Akim Demaille <akim@epita.fr>
5668
5669 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
5670 From Alexandre Duret-Lutz.
5671
5672 2003-08-25 Akim Demaille <akim@epita.fr>

5675
5676 2003-08-25 Akim Demaille <akim@epita.fr>
5677
5678 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
5679 Use them.
5680
5681 2003-08-25 Akim Demaille <akim@epita.fr>
5682
5683 * data/lalr1.cc (Parser::reduce_print_): New.
5684 Use it.
5685
5686 2003-08-25 Akim Demaille <akim@epita.fr>
5687
5688 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
5689 error recovery loops. This patch is based on
5690 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
5691 Also, augment the similarity between lalr1.cc and yacc.c.
5692 Note: the locations of error recovery rules are not correct yet.
5693
5694 * data/lalr1.cc: Comment changes to augment the similarity between
5695 lalr1.cc and yacc.c.
5696 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
5697 (yyerrlab1): Remove, but where it used to be (now the bottom part of
5698 yyerrlab), when hitting EOF, pop the whole stack here instead of
5699 merely falling thru the default error handling mechanism.
5700 (yyerrorlab): New label, with the old contents of YYERROR,
5701 plus the following change: pop the stack of rhs corresponding
5702 to the production that invoked YYERROR. That is how Yacc
5703 behaves (required by POSIX).
5704 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
5705 fail.
5706
5707 2003-08-25 Akim Demaille <akim@epita.fr>
5708
5709 Tune local.at so that people can "autom4te -l autotest calc.at -o
5710 calc" for instance, to extract a sub test suite.
5711
5712 * tests/testsuite.at: Move the initialization, Autotest version
5713 requirement, and AT_TESTED invocation into...
5714 * tests/local.at: here.
5715 * tests/testsuite.at: Include it for compatibility with Autoconf
5716 2.57.
5717 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
5718 be ignore.
5719
5720 2003-08-04 Paul Eggert <eggert@twinsun.com>
5721
5722 Rework code slightly to avoid gcc -Wtraditional warnings.
5723 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
5724 The returned value is now stored in *YY0. All callers changed.
5725 * src/output.c (merge_output): Adjust to the above change.
5726
5727 2003-07-26 Paul Eggert <eggert@twinsun.com>
5728
5729 * data/glr.c (YYASSERT): New macro.
5730 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
5731 yyresolveStates, yyprocessOneStack):
5732 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
5733 Derived from a suggestion by Frank Heckenbach.
5734
5735 2003-07-25 Paul Eggert <eggert@twinsun.com>
5736
5737 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
5738 for portability to K&R C (after ansi2knr, presumably). See
5739 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
5740 by Frank Heckenbach, though I have omitted the structure-initialization
5741 part of his glr-knr.diff patch since I recall that the Portable
5742 C Compiler didn't require that change.
5743
5744 Let the user specify how to allocate and free memory.
5745 Derived from a suggestion by Frank Heckenbach in
5746 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
5747 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
5748 All uses of free, malloc, realloc changed to use these macros,
5749 and unnecessary casts removed.
5750 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
5751
5752 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
5753
5754 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
5755 use s.empty() rather than s == "" to test for empty string; see
5756 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
5757 (trivial change)
5758

5768 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
5769 Remove unnecessary parentheses from uses.

5771 conventions for parentheses.
5772
5773 2003-06-19 Paul Eggert <eggert@twinsun.com>
5774
5775 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
5776 yyreportTree): Do not assume that size_t is the same width as int,
5777 when printing sizes. Print sizes using an unsigned format.
5778 Problem reported by Frank Heckenbach in
5779 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
5780
5781 Port to Forte Developer 7 C compiler.
5782 * data/glr.c (struct YYLTYPE): If locations are not being used,
5783 declare a single dummy member, as empty structs do not conform
5784 to the C standard.
5785 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
5786 the Forte Developer 7 C compiler complains that end-of-loop
5787 code is not reached.
5788
5789 2003-06-17 Paul Eggert <eggert@twinsun.com>
5790
5791 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
5792 avoid warnings from picky compilers about redefinition of PARAMS.
5793

5795
5796 Version 1.875b.
5797
5798 * NEWS: Document 1.875b.
5799
5800 * lib/bbitset.h: Do not include config.h; that's the includer's job.
5801 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
5802 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
5803 Don't use 'index' in comments, as it's a builtin fn on some hosts.
5804 * lib/bitset_stats.c: Include gettext.h unconditionally, as
5805 per recent gettext manual's suggestion.
5806 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
5807 Use prototypes, not old-style definitions.
5808 * lib/lbitset.c (lbitset_unused_clear): Likewise.
5809 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,

5827 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
5828 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
5829 from libbitset.
5830
5831 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
5832 `How Can I Reset @code{yyparse}', since texinfo does not allow
5833 arbitrary @ in node names.
5834
5835 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
5836 shouldn't be needed according to the gettext 0.12.1 documentation
5837 but which seem to be needed anyway: codeset.m4 glibc21.m4
5838 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
5839 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
5840 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
5841
5842 * lib/.cvsignore: Add stdbool.h.
5843 * m4/.cvsignore: Add nls.m4, po.m4.
5844
5845 Upgrade to CVS gnulib.
5846 * stdbool_.h: File renamed from stdbool.h.in.
5847 * configure.ac (AM_STDBOOL_H): Invoke this instead of
5848 AC_HEADER_STDBOOL.
5849 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
5850 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
5851 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
5852 (MOSTLYCLEANFILES): New var.
5853 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
5854 (stdbool.h): New rule.
5855 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
5856 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
5857 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
5858 m4/quote.m4: Upgrade to today's gnulib.
5859
5860 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
5861 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
5862 the tests right now.
5863 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
5864 yyerror are declared before use; C99 requires this.
5865
5866 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5867
5868 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
5869 first.
5870 (yyrecoverSyntaxError): Correct the logic for setting and testing
5871 yyerrState.
5872 Correct comment on handling EOF.
5873 Allow states with only a default reduction, rather than failing
5874 (I can't quite reconstruct why these were not allowed before).
5875
5876 Fixes to avoid problem that $-N rules in GLR parsers can cause
5877 buffer overruns, corrupting state.
5878
5879 * src/output.c (prepare_rules): Output max_left_semantic_context
5880 definition.
5881 * src/reader.h (max_left_semantic_context): New variable declaration.
5882 * src/scan-gram.l (max_left_semantic_context): Define.
5883 (handle_action_dollar): Update max_left_semantic_context.
5884 * data/glr.c (YYMAXLEFT): New definition.
5885 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
5886 (yyresolveAction): Ditto.
5887
5888 Fixes to problems with location handling in GLR parsers reported by
5889 Frank Heckenbach (2003/06/05).
5890
5891 * data/glr.c (YYLTYPE): Make trivial if locations not used.
5892 (YYRHSLOC): Add parentheses, and define only if locations used.
5893 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
5894 locations not used.
5895 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
5896 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
5897
5898 * tests/cxx-type.at: Exercise location information; update tests
5899 to differentiate output with and without locations.
5900 Remove forward declarations of yylex and yyerror---caused errors
5901 because default YYLTYPE not yet defined.
5902 Change semantic actions to compute strings, rather than printing
5903 them directly (to test proper passing of semantics values). Change
5904 output to prefix notation and update test data and expected results.
5905 (yylex): Track locations.
5906 (stmtMerge): Return value rather than printing, and include arguments
5907 in value.
5908
5909 2003-06-03 Paul Eggert <eggert@twinsun.com>
5910
5911 Avoid warnings generated by GCC 2.95.4 when Bison is
5912 configured with --enable-gcc-warnings.
5913 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
5914 yy::]b4_parser_class_name[::translate_,
5915 yy::Stack::operator[] (unsigned),
5916 yy::Stack::operator[] (unsigned) const,
5917 yy::Slice::operator[] (unsigned),
5918 yy::Slice::operator[] (unsigned) const):
5919 Rename local vars to avoid warnings.
5920 * tests/glr-regression.at (Improper handling of embedded actions
5921 and $-N in GLR parsers): Remove unused local variable from yylex.
5922 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
5923 (void) as arg when not pure, since we now assume C89 when building
5924 Bison. Pacify GCC by using parameter.
5925
5926 2003-06-02 Paul Eggert <eggert@twinsun.com>
5927
5928 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
5929 yy::Location::lines, yy::Location::columns): Rename arguments
5930 to avoid shadowing; this removes a warning generated by GCC 3.3.
5931
5932 2003-06-01 Paul Eggert <eggert@twinsun.com>
5933
5934 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
5935 to g++, as GCC 3.3 complains if you do it.
5936 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
5937 everything that WARNING_CFLAGS has, except omit warnings
5938 not suitable for C++.
5939 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
5940 * tests/atlocal.in (CXXFLAGS): New var.
5941 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
5942
5943 Fix a GLR parser bug I reported in February; see
5944 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
5945 The problem was that GLR parsers did not conform to the C standard,
5946 because actions like { $1 = $2 + $3; } expanded to expressions
5947 that invoked YYFILL in separate subexpressions, and YYFILL assigned
5948 to a local variable. The C standard says that expressions
5949 like (var = f ()) + (var = f ()) have undefined behavior.
5950 Another problem was that GCC sometimes issues warnings that
5951 yyfill and its parameters are unused.
5952
5953 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
5954 as possibly unused.
5955 (yyfill): New function.
5956 (YYFILL): Use it.
5957 (yyuserAction): Change type of yynormal to bool, so that it matches
5958 the new yyfill signature. Mark it as possibly unused.
5959
5960
5961 Follow up on a bug I reported in February, where a Bison-generated
5962 parser can loop. Provide a test case and a fix for yacc.c. I
5963 don't have a fix for lalr1.cc or for glr.c, unfortunately.
5964 The original bug report is in:
5965 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
5966
5967 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
5968 macro's size was becoming unwieldy.
5969 (yyerrlab): Do not discard an empty lookahead symbol, as this
5970 might destroy garbage.
5971 (yyerrorlab): New label, with the old contents of YYERROR,
5972 plus the following change: pop the stack of rhs corresponding
5973 to the production that invoked YYERROR. That is how Yacc
5974 behaves, and POSIX requires this behavior.
5975 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
5976 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
5977 Define 'alarm' to do nothing if unistd.h is not available.
5978 Add a new rule "exp: '-' error;" to test the above change to
5979 data/yacc.c. Use 'alarm' to abort any test taking longer than
5980 10 seconds, as it's probably looping.
5981 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
5982 Also, the new yacc.c generates two fewer diagnostics for an
5983 existing test.
5984
5985 2003-05-24 Paul Eggert <eggert@twinsun.com>
5986
5987 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
5988 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
5989 This fixes a problem reported by John Bowman when the Compaq/HP
5990 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
5991 -ansi -Wall -gall).
5992 * data/yacc.c (union yyalloc): Likewise.
5993 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
5994
5995 Switch from 'int' to 'bool' where that makes sense.
5996

6000 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
6001 Return or accept bool, not int. All callers changed.

6006 bitset_or_and_cmp_): Likewise.
6007 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
6008 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
6009 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
6010 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
6011 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
6012 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
6013 bitset_stats_or_and_cmp): Likewise.
6014 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
6015 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
6016 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
6017 ebitset_xor_cmp): Likewise.
6018 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
6019 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
6020 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
6021 lbitset_xor_cmp): Likewise.
6022 * lib/bbitset.h: Include <stdbool.h>.
6023 (struct bitset_vtable): The following members now return bool, not
6024 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
6025 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
6026 or_and_cmp).
6027 * src/conflicts.c (count_rr_conflicts): Likewise.
6028 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
6029 All uses changed.
6030 * lib/ebitset.c (ebitset_obstack_init): Likewise.
6031 * lib/lbitset.c (lbitset_obstack_init): Likewise.
6032 * src/getargs.c (debug_flag, defines_flag, locations_flag,
6033 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
6034 graph_flag): Likewise.
6035 * src/getargs.h (debug_flag, defines_flag, locations_flag,
6036 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
6037 graph_flag): Likewise.
6038 * src/output.c (error_verbose): Likewise.
6039 * src/output.h (error_verbose): Likewise.
6040 * src/reader.c (start_flag, typed): Likewise.
6041 * src/reader.h (typed): Likewise.
6042 * src/getargs.c (LOCATIONS_OPTION): New constant.
6043 (long_options, getargs): Use it.
6044 * src/lalr.c (build_relations): Use bool, not int.
6045 * src/nullable.c (nullable_compute): Likewise.
6046 * src/print.c (print_reductions): Likewise.
6047 * src/tables.c (action_row, pack_vector): Likewise.
6048 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
6049 * src/output.c (prepare): Use it.
6050 * src/output.c (token_definitions_output,
6051 symbol_destructors_output, symbol_destructors_output): Use string,
6052 not boolean integer, to keep track of whether to output separator.
6053 * src/print_graph.c (print_core): Likewise.
6054 * src/state.c (state_rule_lookaheads_print): Likewise.
6055
6056 * config/install-sh: Sync from automake 1.7.5.
6057
6058 2003-05-14 Paul Eggert <eggert@twinsun.com>
6059
6060 * src/parse-gram.y (rules_or_grammar_declaration): Require a
6061 semicolon after a grammar declaration, in the interest of possible
6062 future changes to the Bison input language.
6063 Do not allow a stray semicolon at the start of the grammar.
6064 (rhses.1): Allow one or more semicolons after any rule, including
6065 just before "|" as required by POSIX.
6066 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
6067 grammar.
6068
6069 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6070
6071 %parse-param support for lalr1.cc.
6072
6073 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
6074 b4_cc_constructor_calls, b4_cc_constructor_call,
6075 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
6076 definitions.
6077 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
6078 parse-param arguments.
6079 (yy::b4_parser_class_name): Declare instance variables to
6080 hold parse-param arguments.
6081 * tests/calc.at: s/value/semantic_value/ because value clashes
6082 with a member of yy::b4_parser_class_name. Adjust C++ code
6083 to handle %parse-param. Enable %parse-param test in C++.
6084
6085 2003-05-12 Paul Eggert <eggert@twinsun.com>
6086
6087 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
6088 English a bit. Fix fclose typo. Change "const char" to "char
6089 const", and use ANSI C rather than K&R for "main". Suggest
6090 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
6091 and suggest yy_switch_to_buffer.
6092
6093 2003-05-05 Paul Eggert <eggert@twinsun.com>
6094
6095 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
6096 C89. This avoids a diagnostic on compilers that define __STDC__
6097 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
6098 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
6099
6100 2003-05-03 Paul Eggert <eggert@twinsun.com>
6101
6102 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
6103 Do not overrun array bounds.
6104 This should fix a bug reported today by Olatunji Oluwabukunmi in
6105 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
6106
6107 2003-04-29 Akim Demaille <akim@epita.fr>
6108
6109 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
6110 * src/getargs.c, src/getargs.h: here, as bool, not int.
6111 (nondeterministic_parser): New.
6112 * src/parse-gram.y, src/scan-gram.l: Support
6113 %nondeterministic-parser.
6114 * src/output.c (prepare): Use nondeterministic_parser instead
6115 of glr_parser where appropriate.
6116 * src/tables.c (conflict_row, action_row, save_row)
6117 (token_actions, token_actions, pack_vector): Ditto.
6118
6119 2003-04-29 Akim Demaille <akim@epita.fr>
6120
6121 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
6122
6123 2003-04-29 Akim Demaille <akim@epita.fr>
6124
6125 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
6126 with %pure-parser and %locations to exercise the patch from Yakov
6127 Markovitch below.
6128
6129 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
6130
6131 * data/yacc.c: (b4_lex_param): Corrected for the case where
6132 %lex-param is provided and %pure-parser isn't.
6133
6134 2003-04-27 Paul Eggert <eggert@twinsun.com>
6135
6136 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
6137 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
6138 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
6139 if it is not defined.
6140 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
6141
6142 2003-04-26 Paul Eggert <eggert@twinsun.com>
6143
6144 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
6145 Declare to be of type suitable for the ninf value itself, not of
6146 type suitable for the corresponding table, since the latter might
6147 be unsigned but the ninf value might be negative. This fixes a
6148 bug reported by Alexandre Duret-Lutz in
6149 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
6150
6151 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
6152 invokes it. We shouldn't invoke it twice because it will attempt
6153 to put error.o in the archive twice. This fixes a glitch reported
6154 by Martin Mokrejs in
6155 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
6156
6157 2003-04-21 Paul Eggert <eggert@twinsun.com>
6158
6159 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
6160 to gnulib.
6161
6162 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
6163
6164 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
6165 Fix obvious typo that results in uncompilable GLR parsers
6166 when both %pure-parser and %locations are used. (trivial change)
6167
6168 2003-04-17 Paul Eggert <eggert@twinsun.com>
6169
6170 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
6171 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
6172 Do not insert the expected token via unput, as this runs afoul
6173 of a POSIX-compatibility bug in flex 2.5.31.
6174 All uses changed to BEGIN the parent state,
6175 since we no longer insert the expected token via unput.
6176 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
6177 that is no longer emitted after the above change.
6178
6179 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
6180 the first one. This change is from Paul Hilfinger, and it fixes
6181 regression reported by Werner Lemberg in
6182 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
6183
6184 (resolve_sr_conflict): Don't invoke state_errs_set
6185 unless one or more tokens have been explicitly made errors.
6186 Otherwise, the above change causes Bison to abort.
6187
6188 * tests/existing.at (GNU pic Grammar): New test case, taken from
6189 Lemberg's email.
6190
6191 2003-03-31 Akim Demaille <akim@epita.fr>
6192
6193 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
6194
6195 2003-03-31 Akim Demaille <akim@epita.fr>
6196
6197 * src/output.c (prepare_symbols): Avoid trailing spaces in the
6198 output.
6199
6200 2003-03-31 Akim Demaille <akim@epita.fr>
6201
6202 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
6203 From Paul Hilfinger.
6204
6205 2003-03-29 Akim Demaille <akim@epita.fr>
6206
6207 * m4/error.m4: Do not put under dynamic conditions some code which
6208 expansion is under static control.
6209
6210 2003-03-29 Akim Demaille <akim@epita.fr>
6211
6212 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
6213
6214 2003-03-29 Akim Demaille <akim@epita.fr>
6215
6216 * doc/bison.texinfo (Strings are Destroyed): New.
6217
6218 2003-03-13 Paul Eggert <eggert@twinsun.com>
6219
6220 * .cvsignore: Add configure.lineno.
6221 * src/.cvsignore: Add yacc.
6222 * tests/.cvsignore: Add testsuite.log.
6223 * doc/fdl.texi: Sync with latest FSF version.
6224
6225 2003-03-12 Paul Eggert <eggert@twinsun.com>
6226
6227 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
6228 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
6229 cursor, instead of leaving it undefined. This fixes a bug
6230 reported by Tim Van Holder in
6231 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
6232 * tests/input.at (Torturing the Scanner): Test the scanner on
6233 an empty input file, which was Tim Van Holder's test case.
6234
6235 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
6236 <sys/resource.h> can be included, include sys/time.h and
6237 sys/times.h first, if available. This works around the SunOS
6238 4.1.4 porting bug reported by Bruce Becker in
6239 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
6240
6241 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
6242 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
6243 AC_HEADER_SYS_WAIT.
6244
6245 Merge changes from gnulib. This was prompted because the CVS
6246 snapshot didn't build on Solaris 7 due to strnlen problems.
6247
6248 These changes need to be merged back into gnulib:
6249 * lib/hash.c: Include <stdbool.h> unconditionally.
6250 * m4/onceonly.m4 (m4_quote): New macro.
6251 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
6252 Quote AC_FOREACH variable-expansions properly.
6253 The 2003-01-03 obstack.h change also needs merging.
6254 {end of changes requiring merging}
6255
6256 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,

6259 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
6260 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
6261 New files, imported from gnulib.
6262 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
6263 above.
6264
6265 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
6266 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
6267 gnulib sources.
6268
6269 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
6270 Add.
6271 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
6272 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
6273 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
6274 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
6275 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
6276 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
6277 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
6278 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
6279 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
6280 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
6281 (jm_PREREQ_ARGMATCH): Remove.
6282 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
6283 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
6284
6285 * src/system.h: Include <stdbool.h> unconditionally.
6286
6287 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
6288 assuming at least C89 in the bitset code for some time now.
6289
6290 2003-03-03 Akim Demaille <akim@epita.fr>
6291
6292 * ro.po: New.
6293
6294 2003-03-02 Akim Demaille <akim@epita.fr>
6295
6296 * doc/bison.texinfo (Table of Symbols): Reactivate the
6297 documentation for %lex-param, and %parse-param.
6298
6299 2003-03-02 Akim Demaille <akim@epita.fr>
6300
6301 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
6302 generate verbose error messages.
6303 Use the number of tokens as an upper bound in yytname, as it
6304 cannot be a non terminal.
6305
6306 2003-03-02 Akim Demaille <akim@epita.fr>
6307
6308 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
6309 message.
6310
6311 2003-03-02 Akim Demaille <akim@epita.fr>
6312
6313 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
6314 Use them to exercise yycheck overrun.
6315 Based on Andrew Suffield's grammar.
6316
6317 2003-03-02 Akim Demaille <akim@epita.fr>
6318
6319 Create tests/local.at for Bison generic testing macros.
6320
6321 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
6322 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
6323 This new file.
6324 * tests/calc.at (AT_CHECK_CALC): Adjust.
6325 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
6326 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
6327 * tests/local.at: here.
6328 (AT_COMPILE_CXX): Tags the tests using it as c++.
6329 Ignore the test if CXX is not functional.
6330
6331 2003-03-01 Paul Eggert <eggert@twinsun.com>
6332
6333 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
6334 not loc->end, since loc->end might contain garbage and this leads
6335 to undefined behavior on some platforms.
6336 (id_loc, token_start): Use (IF_LINTed) initial values that do not
6337 depend on *loc, so that the reader doesn't give the the false
6338 impression that *loc is initialized.
6339 (<INITIAL>"%%"): Do not bother setting code_start, since its value
6340 does not survive the return.
6341
6342 2003-03-01 Akim Demaille <akim@epita.fr>
6343
6344 * src/scan-gram.l (code_start): Always initialize it when entering
6345 into yylex, as SC_EPILOGUE is activated *before* the corresponding
6346 yylex invocation. An alternative would be making it static, but
6347 then it starts with the second %%'s beginning, instead of its end.
6348
6349 2003-02-28 Paul Eggert <eggert@twinsun.com>
6350
6351 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
6352 around a UnixWare 7.1.1 porting bug reported by John Hughes in
6353 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
6354
6355 2003-02-26 Paul Eggert <eggert@twinsun.com>
6356
6357 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
6358 Remove Sequent/Pyramid discussion (nobody uses them any more).
6359 Merge VMS and MS-DOS discussion; these ports may well be dead
6360 but let's keep mentioning them for now. Put <> around email
6361 addresses. Add copyright notice.
6362
6363 2003-02-24 Paul Eggert <eggert@twinsun.com>
6364
6365 * data/glr.c (yy_reduce_print): yylineno -> yylno,
6366 to avoid collision with flex use of yylineno.
6367 Problem reported by Bruce Lilly in
6368 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
6369 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
6370 * data/yacc.c (yy_reduce_print): Likewise.

6373
6374 2003-02-21 Akim Demaille <akim@epita.fr>
6375
6376 * data/lalr1.cc: Use temporary variables instead of casts to
6377 change integer types.
6378 Suggested by Paul Eggert.
6379
6380 2003-02-21 Akim Demaille <akim@epita.fr>
6381
6382 * doc/bison.texinfo: Use "location" consistently to refer to @n,
6383 to avoid confusions with lalr1.cc's notion of Position.
6384 Suggested by Paul Eggert.
6385
6386 2003-02-20 Akim Demaille <akim@epita.fr>
6387
6388 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
6389 before initial_columns.
6390 (location.hh): Use consistent variable names when defining the
6391 operator<<.
6392 Use "last" so that we subtract from Positions, not from unsigned.
6393
6394 2003-02-20 Akim Demaille <akim@epita.fr>
6395
6396 * data/lalr1.cc (position.hh): New subfile, including the extended
6397 and Doxygen'ed documentation of class Position.
6398 (location.hh): Use it.
6399 Document a` la Doxygen.
6400 With the help of Benoit Perrot.
6401
6402 2003-02-20 Akim Demaille <akim@epita.fr>
6403
6404 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
6405 AT_YACC_IF.
6406 Redefine AT_YYERROR_SEES_LOC_IF using it.
6407 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
6408 not defined.
6409 Don't use the location in yy::Parser::error_ and
6410 yy::Parser::print_ when not %locations.
6411 Activate more lalr1.cc tests.
6412
6413 2003-02-19 Akim Demaille <akim@epita.fr>
6414
6415 * data/lalr1.cc: When displaying a line number, be sure to make it
6416 an int.
6417
6418 2003-02-19 Akim Demaille <akim@epita.fr>
6419
6420 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
6421 Remove, useless.
6422 (YYABORT, YYACCEPT, YYERROR): New.
6423 * tests/calc.at: Renable the lalr1.cc test.
6424
6425 2003-02-19 Akim Demaille <akim@epita.fr>
6426
6427 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
6428 error recovery, mixing with/without pops and discarding of the
6429 lookahead.
6430 Exercise YYERROR.
6431 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
6432
6433 2003-02-17 Paul Eggert <eggert@twinsun.com>
6434
6435 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
6436 * tests/testsuite.at (AT_COMPILE): Use them.
6437 This fixes the testsuite problem reported by Robert Lentz in
6438 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
6439
6440 2003-02-12 Paul Eggert <eggert@twinsun.com>
6441
6442 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
6443 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
6444 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
6445 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
6446 Check for malloc failure, for consistency with yacc.c.
6447 (yytname_size): Remove, for consistency with yacc.c.
6448
6449 The bug still remains in data/lalr1.cc, as I didn't have time
6450 to fix it there.
6451
6452 2003-02-06 Akim Demaille <akim@epita.fr>
6453
6454 * configure.ac (GXX): Rename as...
6455 (CXX): this, to keep the original Autoconf semantics.
6456 Require 2.57.
6457 * data/lalr1.cc: Fix b4_copyright invocations.
6458 If YYDEBUG is not defined, don't depend upon name_ being defined.

6460 (Position::filename): New member.
6461 (Position::Position ()): New.
6462 (operator<< (Position)): New.
6463 (operator- (Position, int)): New.
6464 (Location::first, Location::last): Rename as...
6465 (Location::begin, Location::end): these, to mock the conventional
6466 iterator names.
6467 (operator<< (Location)): New.
6468 * tests/atlocal.in (CXX): New.
6469 * tests/testsuite.at (AT_COMPILE_CXX): New.
6470 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
6471 locations in a more synthetic way.
6472 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
6473 lalr1.cc is used.
6474 Adjust the C locations to match those from Emacs: first column is
6475 column 0.
6476 Change all the expected results.
6477 Conform to the GCS: simplify the locations when applicable.
6478 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
6479 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
6480 these CPP macros with the m4 macros new defined by...
6481 (AT_CHECK_PUSHDEFS): this, i.e.:
6482 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
6483 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
6484 New macros.
6485 (AT_CHECK_POPDEFS): Undefine them.
6486 (AT_CHECK_CALC_LALR1_CC): New.
6487 Use it for the first lalr1.cc test.
6488
6489 2003-02-04 Akim Demaille <akim@epita.fr>
6490
6491 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
6492 Location as is defined.
6493
6494 2003-02-04 Akim Demaille <akim@epita.fr>
6495
6496 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
6497 name_ being defined.
6498
6499 2003-02-03 Paul Eggert <eggert@twinsun.com>
6500
6501 * src/gram.h (start_symbol): Remove unused decl.
6502
6503 Use more-consistent naming conventions for local vars.
6504
6505 * src/derives.c (derives_compute): Change type of local var from
6506 int to rule_number.
6507 * src/gram.c (grammar_rules_partial_print): Likewise.
6508 * src/print.c (print_core): Likewise.
6509 * src/reduce.c (reduce_grammar_tables): Likewise.
6510
6511 * src/gram.c (grammar_dump): Change name of item_number *
6512 local var from r to rp.
6513 * src/nullable.c (nullable_compute): Likewise.
6514
6515 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
6516
6517 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
6518 for symbol or symbol_number var.
6519 * src/reader.c (grammar_start_symbol_set): Likewise.
6520 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
6521 Likewise.
6522 * src/state.c (transitions_to): Likewise.
6523 * src/state.h: Likewise.
6524 * src/tables.c (symbol_number_to_vector_number): Likewise.
6525
6526 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
6527 char * var.
6528
6529 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
6530 var.
6531
6532 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
6533 var.
6534
6535 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
6536 Use str, not s, for char * var. Use ch, not c, for character var.
6537 Use size for size var.
6538

6540 char * var.
6541 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for

6547 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
6548 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
6549 param to have same name as that of enum, so that we don't use
6550 "s" to stand for a non-state.
6551
6552 2003-02-02 Akim Demaille <akim@epita.fr>
6553
6554 * src/scan-skel.l: Scan more than one inert character per yylex
6555 invocation.
6556
6557 2003-02-01 Paul Eggert <eggert@twinsun.com>
6558
6559 Version 1.875a.
6560
6561 * po/LINGUAS: Add ms.
6562
6563 2003-01-30 Akim Demaille <akim@epita.fr>
6564
6565 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
6566
6567 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6568
6569 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
6570 of $1.
6571
6572 Changes in response to error report by S. Eken: GLR mode does not
6573 handle negative $ indices or $ indices in embedded rules correctly.
6574 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
6575
6576 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
6577 (b4_rhs_location): Ditto.
6578 (yyfill): New function to copy from stack tree into array
6579 incrementally.
6580 (yyuserAction): Modify to allow incremental move of semantic values
6581 to rhs array when in GLR mode.
6582 Define YYFILL to use in user-defined actions to fill semantic array
6583 as needed.
6584 Remove dummy use of yystack, as there is now a guaranteed use.
6585 (yydoAction): Modify to allow incremental move of semantic values
6586 to rhs array when in GLR mode.
6587 (yyresolveAction): Ditto.
6588 (yyglrShiftDefer): Update comment.
6589 (yyresolveStates): Use X == NULL for pointers, not !X.
6590 (yyglrReduce): Ditto.
6591 (yydoAction): Ditto
6592
6593 * tests/glr-regr1.at: Rename to ...
6594 * tests/glr-regression.at: Add new regression test for the problems
6595 described above (adapted from S. Eken).
6596 Update copyright notice.
6597 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
6598 * tests/Makefile.am: Ditto.
6599
6600 2003-01-28 Paul Eggert <eggert@twinsun.com>
6601
6602 * data/lalr1.cc: Do not use @output_header_name@ unless
6603 b4_defines_flag is set. This fixes two bugs reported by
6604 Tim Van Holder in
6605 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
6606 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
6607
6608 2003-01-21 Paul Eggert <eggert@twinsun.com>
6609
6610 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
6611 we don't need to worry about yyerrlab1 being reported as an
6612 "unused label" by non-GCC C compilers. The downside is that if
6613 locations are used then a couple of statements are duplicated each
6614 time YYERROR is invoked, but the upside is that the warnings
6615 should vanish.
6616 (yyerrlab1): Move code to YERROR.
6617 (yyerrlab2): Remove. Change uses back to yyerrlab1.
6618 This reverts some of the 2002-12-27 change.
6619
6620 2003-01-17 Paul Eggert <eggert@twinsun.com>
6621
6622 * src/output.c (symbol_printers_output): Fix typo that led
6623 to core dump. Problem reported by Antonio Rus in
6624 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
6625
6626 2003-01-13 Akim Demaille <akim@epita.fr>,
6627 Quoc Peyrot <chojin@lrde.epita.fr>,
6628 Robert Anisko <anisko_r@lrde.epita.fr>
6629
6630 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
6631 when the stacks contain one element, as the loop would otherwise
6632 free the last state, and then use the top state (the one we just
6633 popped). This means that the initial elements will not be freed
6634 explicitly, as is the case in yacc.c; it is not a problem, as
6635 these elements have fake values.
6636
6637 2003-01-11 Paul Eggert <eggert@twinsun.com>
6638
6639 * NEWS: %expect-violations are now just warnings, reverting
6640 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
6641 bootstrapping problem reported by Matthias Klose; see
6642 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
6643 * src/conflicts.c (conflicts_print): Likewise.
6644 * tests/conflicts.at (%expect not enough, %expect too much,
6645 %expect with reduce conflicts): Likewise.
6646 * doc/bison.texinfo (Expect Decl): Document this. Also mention
6647 that the warning is enabled if the number of conflicts changes
6648 (not necessarily increases).
6649
6650 * src/getargs.c (version): Update copyright year.
6651
6652 2003-01-09 Akim Demaille <akim@epita.fr>
6653
6654 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
6655
6656 2003-01-08 Paul Eggert <eggert@twinsun.com>
6657
6658 * Makefile.maint (WGETFLAGS):
6659 New macro, containing "-C off" to disable proxy caches.
6660 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
6661 (rel-check): Use $(WGET) instead of wget.
6662
6663 2003-01-06 Paul Eggert <eggert@twinsun.com>
6664
6665 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
6666 the GLR paper of Scott, Johnstone and Hussain.
6667
6668 2003-01-04 Paul Eggert <eggert@twinsun.com>
6669
6670 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
6671 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
6672 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
6673 (EXTRA_LIBRARIES): New var, for liby.a.
6674 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
6675 (EXTRA_SCRIPTS): New var, for yacc.
6676
6677 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
6678 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
6679 Problem reported by Nelson H. F. Beebe.
6680
6681 2003-01-03 Paul Eggert <eggert@twinsun.com>
6682
6683 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
6684 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
6685 when compiling Bison 1.875's `bitset bset = obstack_alloc
6686 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
6687
6688 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
6689 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
6690 grow to a huge size with typical invocation.
6691
6692 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
6693 Use the pattern recommended by Autoconf 2.57, except also protect
6694 against double-definition.
6695 * src/system.h: Likewise.
6696 Portability issues reported by Nelson H. F. Beebe.
6697
6698 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
6699 All uses changed. Provide a definition in both C and C++.
6700 (yytrue, yyfalse): Define even if defined (__cplusplus).
6701
6702 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
6703 Reported by Nelson H. F. Beebe.
6704
6705 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
6706
6707 2003-01-02 Paul Eggert <eggert@twinsun.com>
6708
6709 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
6710 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
6711 Bug reported by Nelson H. F. Beebe.
6712
6713 2003-01-01 Paul Eggert <eggert@twinsun.com>
6714
6715 * Version 1.875.
6716
6717 2002-12-30 Paul Eggert <eggert@twinsun.com>
6718
6719 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
6720 Moved here from...
6721 (<INITIAL>","): Here. This causes stray "," to be treated
6722 more uniformly.
6723
6724 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
6725 last brace in braced code when not in Yacc mode, for compatibility
6726 with Bison 1.35. This resurrects the 2001-12-15 patch to
6727 src/reader.c.
6728
6729 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
6730 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
6731
6732 2002-12-28 Paul Eggert <eggert@twinsun.com>
6733
6734 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
6735 that of SYM's type. This fixes Debian bug 168069, reported by
6736 Thomas Olsson.
6737
6738 2002-12-28 Paul Eggert <eggert@twinsun.com>
6739
6740 Version 1.75f.
6741
6742 Switch back to the Yacc style of conflict reports, undoing some
6743 of the 2002-07-30 change.
6744 * doc/bison.texinfo (Understanding): Use Yacc style for
6745 conflict reports. Also, use new way of locating rules.
6746 * src/conflicts.c (conflict_report):
6747 Renamed from conflict_report_yacc, removing the old
6748 'conflict_report'. Translate the entire conflict report at once,
6749 so that we don't assume that "," has the same interpretation in
6750 all languages.
6751 (conflicts_output): Use Yacc-style conflict report for each state,
6752 instead of our more-complicated style.
6753 (conflicts_print): Use Yacc-style conflict report, except print
6754 the input file name when not emulating Yacc.
6755 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
6756 Conflicted Reduction, %expect not enough, %expect too much,
6757 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
6758 * tests/existing.at (GNU Cim Grammar): Likewise.
6759 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
6760
6761 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
6762 fatal): Don't invoke fflush; it's not needed and it might even be
6763 harmful for stdout, as stdout might not be open.
6764 * src/reduce.c (reduce_print): Likewise.
6765
6766 2002-12-27 Paul Eggert <eggert@twinsun.com>
6767
6768 Fix a bug where error locations were not being recorded correctly.
6769 This problem was originally reported by Paul Hilfinger in
6770 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
6771
6772 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6773 top of the location stack's error locations.
6774 (yyerrlab): Set it. When discarding a token, push its location
6775 onto yylerrsp so that we don't lose track of the error's end.
6776 (yyerrlab1): Now is only the target of YYERROR, so that we can
6777 properly record the location of the action that failed. For GCC
6778 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6779 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6780 (yyerrlab2): New label, which yyerrlab now falls through to.
6781 Compute the error's location by applying YYLLOC_DEFAULT to
6782 the locations of all the symbols that went into the error.
6783 * doc/bison.texinfo (Location Default Action): Mention that
6784 YYLLOC_DEFAULT is also invoked for syntax errors.
6785 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6786 Error locations include the locations of all the tokens that were
6787 discarded, not just the last token.
6788
6789 2002-12-26 Paul Eggert <eggert@twinsun.com>
6790
6791 * src/files.c: Include quote.h.
6792 (compute_output_file_names): Warn if we detect conflicting
6793 outputs to the same file. This should catch the misunderstanding
6794 exemplified by Debian Bug 165349, reported by Bruce Stephens..
6795
6796 * src/conflicts.c (conflicts_print): If the user specifies
6797 "%expect N", report an error if there are any reduce/reduce
6798 conflicts. This is what the manual says should happen.
6799 This fixes Debian bug 130890, reported by Anthony DeRobertis.
6800 * tests/conflicts.at (%expect with reduce conflicts): New test.
6801
6802 Don't use m4_include on relative file names, as it doesn't work as
6803 desired if there happens to be a file with that name under ".".
6804
6805 * m4sugar/version.m4: Remove; it was included but it wasn't used.
6806 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
6807 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
6808 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
6809 * src/output.c (output_skeleton): Use full path names when
6810 specifying a file to include; don't rely on include path, as
6811 it's unreliable when the working file contains a file with
6812 that name.
6813
6814 2002-12-25 Paul Eggert <eggert@twinsun.com>
6815
6816 Remove obsolete references to bison.simple and bison.hairy.
6817 Problem mentioned by Aubin Mahe in
6818 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
6819 * data/glr.c: Comment fix.
6820 * doc/bison.1: Remove references. Also, mention "yacc".
6821
6822 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
6823 with -g option.
6824
6825 * src/parse-gram.y (declaration): Use enum "report_states" rather
6826 than its numeric value 1.
6827
6828 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
6829 opening a new one. This fixes Debian bug 165349, reported by
6830 Bruce Stephens.
6831
6832 2002-12-24 Paul Eggert <eggert@twinsun.com>
6833
6834 Version 1.75e.
6835
6836 * Makefile.maint (cvs-update): Don't assume that the shell
6837 supports $(...), as Solaris sh doesn't.
6838
6839 * src/parse-gram.y (lloc_default): Remove test for empty
6840 nonterminals at the end, since it didn't change the result.
6841
6842 2002-12-24 Paul Eggert <eggert@twinsun.com>
6843
6844 If the user does not define YYSTYPE as a macro, Bison now declares it
6845 using typedef instead of defining it as a macro. POSIX requires this.
6846 For consistency, YYLTYPE is also declared instead of defined.
6847
6848 %union directives can now have a tag before the `{', e.g., the
6849 directive `%union foo {...}' now generates the C code
6850 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
6851 The default union tag is `YYSTYPE', for compatibility with Solaris 9
6852 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
6853 instead of `yyltype'.
6854
6855 `yystype' and `yyltype' are now obsolescent macros instead of being
6856 typedefs or tags; they are no longer documented and will be
6857 withdrawn in a future release.
6858
6859 * data/glr.c (b4_location_type): Remove.
6860 (YYSTYPE): Renamed from yystype.
6861 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
6862 (struct YYLTYPE): Renamed from struct yyltype.
6863 (YYLTYPE): Renamed from yyltype.
6864 (yyltype, yystype): New (and obsolescent) macros,
6865 for backward compatibility.
6866 * data/yacc.c: Likewise.
6867
6868 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
6869 does not specify a union tag. This is for compatibility with
6870 Solaris 9 yacc.
6871
6872 * src/parse-gram.y (add_param): 2nd arg is now char * not char
6873 const *, since it is now modified by stripping surrounding { }.
6874 (current_braced_code): Remove.
6875 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
6876 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
6877 trailing " {...}". Now of type <chars>.
6878 (grammar_declaration): Adjust to bundled tokens.
6879 (code_content): Remove; stripping is now done by add_param.
6880 (print_token_value): Print contents of bundled tokens.
6881 (token_name): New function.
6882
6883 * src/reader.h (braced_code, current_braced_code): Remove.
6884 (token_name): New decl.
6885
6886 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
6887 token_type, not braced_code code_kind. All uses changed.
6888 (SC_PRE_CODE): New state, for scanning after a keyword that
6889 has (or usually has) an immediately-following braced code.
6890 (token_type): New local var, to keep track of which token type
6891 to return when scanning braced code.
6892 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
6893 <INITIAL>"%parse-param", <INITIAL>"%printer",
6894 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
6895 instead of returning a token type immediately.
6896 (<INITIAL>"{"): Set token type.
6897 (<SC_BRACED_CODE>"}"): Use it.
6898 (handle_action_dollar, handle_action_at): Now returns bool
6899 indicating success. Fail if ! current_rule; this prevents a core dump.
6900 (handle_symbol_code_dollar, handle_symbol_code_at):
6901 Remove; merge body into caller.
6902 (handle_dollar, handle_at): Complain in invalid contexts.
6903
6904 * NEWS, doc/bison.texinfo: Document the above.
6905 * NEWS: Fix years and program names in copyright notice.
6906
6907 2002-12-17 Paul Eggert <eggert@twinsun.com>
6908
6909 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
6910 Reporting, Table of Symbols): Omit mentions of %lex-param and
6911 %parse-param from the documentation for now.
6912
6913 2002-12-15 Paul Eggert <eggert@twinsun.com>
6914
6915 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
6916 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
6917 lookahead symbol, and which sets yychar in parser actions) and it
6918 disagreed with the Bison documentation. Bug
6919 reported by Andrew Walrond.
6920
6921 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
6922 as the caller now does that.
6923 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
6924 (YYEMPTY): Parenthesize right hand side, since others use it.
6925 (yyparse): Don't assume that our generated code is the only code
6926 that sets yychar.
6927
6928 2002-12-13 Paul Eggert <eggert@twinsun.com>
6929
6930 Version 1.75d.
6931
6932 POSIX requires a "yacc" command.
6933 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
6934 (MOSTLYCLEANFILES): Add yacc.
6935 (yacc): New rule.
6936 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
6937 as an alias for bison y.
6938
6939 * po/LINGUAS: Add da.
6940
6941 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
6942 problem with latest <getopt.h>.
6943 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
6944
6945 * doc/fdl.texi: Upgrade to 1.2.
6946 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
6947 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
6948 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
6949 gnulib.
6950 * config/install-sh: Sync with autotools.
6951
6952 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
6953 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
6954 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
6955 locations are requested.
6956 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
6957 locations are requested.
6958
6959 2002-12-12 Paul Eggert <eggert@twinsun.com>
6960
6961 Remove unportable casts and storage allocation tricks.
6962 While we're at it, remove almost all casts, since they
6963 usually aren't needed and are a sign of trouble.
6964
6965 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
6966
6967 * src/derives.c (derives_compute): Do not subtract NTOKENS from
6968 the pointer DSET returned by malloc; this isn't portable.
6969 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
6970 Similarly for DERIVES.
6971 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
6972 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
6973 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
6974
6975 * src/derives.c (derives_compute): Do not bother invoking
6976 int_of_rule_number, since rule numbers are integers.
6977
6978 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
6979 rather than XMALLOC (char, N).
6980
6981 * src/files.c (filename_split): Rewrite to avoid cast.
6982
6983 * src/gram.h (symbol_number_as_item_number,
6984 item_number_as_symbol_number, rule_number_as_item_number,
6985 item_number_as_rule_number):
6986 Now inline functions rather than macros, to avoid casts.
6987 * src/state.h (state_number_as_int): Likewise.
6988 * src/tables.c (state_number_to_vector_number,
6989 symbol_number_to_vector_number): Likewise.
6990
6991 * src/gram.h (int_of_rule_number): Remove; no longer used.
6992
6993 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
6994 since the resulting storage is always stored into.
6995
6996 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
6997 where it's needed.
6998
6999 * src/muscle_tab.c (muscle_m4_output):
7000 Now inline. Return bool, not int.
7001 * src/state.c (state_compare): Likewise.
7002 * src/symtab.c (symbol_check_defined,
7003 symbol_check_alias_consistency, symbol_pack, symbol_translation,
7004 hash_compare_symbol, hash_symbol):
7005 Likewise.
7006 * src/uniqstr.c (uniqstr_print): Likewise.
7007 * src/muscle_tab.c (muscle_m4_output_processor):
7008 New function, to avoid casts.
7009 * src/state.c (state_comparator, stage_hasher): Likewise.
7010 * src/symtab.c (symbol_check_defined_processor,
7011 symbol_check_alias_consistency_processor, symbol_pack_processor,
7012 symbol_translation_processor, hash_symbol_comparator,
7013 hash_symbol_hasher): Likewise.
7014 * src/uniqstr.c (uniqstr_print_processor): Likewise.
7015 * src/muscle_tab.c (muscles_m4_output):
7016 Use new functions instead of casting old functions unportably.
7017 * src/state.c (state_hash_new): Likewise.
7018 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
7019 symbols_token_translations_init):
7020 Likewise.
7021 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
7022
7023 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
7024 var instead of casting to long, to avoid casts.
7025 (prepare_states): Use MALLOC rather than alloca, so that we don't
7026 have to worry about alloca.
7027 * src/state.c (state_hash_lookup): Likewise.
7028
7029 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
7030 local var instead of casting to unsigned char, to avoid casts.
7031
7032 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
7033 STATE_ALLOC): Remove.
7034 (transitions_new, errs_new, reductions_new, state_new): Use malloc
7035 rather than calloc, and use offsetof to avoid allocating slightly
7036 too much storage.
7037 (state_new): Initialize all members.
7038
7039 * src/state.c (state_hash): Use unsigned accumulator, not signed.
7040
7041 * src/symtab.c (symbol_free): Remove; unused.
7042 (symbol_get): Remove cast in lhs of assignment.
7043 (symbols_do): Now static. Accept generic arguments, not
7044 hashing-related ones.
7045
7046 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
7047 (symbol_processor): Remove.
7048 (symbols_do): Remove decl; now static.
7049
7050 * src/system.h (alloca): Remove; decl no longer needed.
7051 (<stddef.h>): Include, for offsetof.
7052 (<inttypes.>, <stdint.h>): Include if available.
7053 (uintptr_t): New type, if system lacks it.
7054 (CALLOC, MALLOC, REALLOC): New macros.
7055 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
7056 new macros.
7057
7058 * src/tables.c (table_size): Now int, to pacify GCC.
7059 (table_grow, table_ninf_remap): Use signed table size.
7060 (save_row): Don't bother initializing locals when not needed.
7061 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
7062 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
7063
7064 * src/vcg.h: Correct misspellings.
7065
7066 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
7067
7068
7069 * src/getargs.c (getargs): Don't assume EOF == -1.
7070
7071 2002-12-09 Paul Eggert <eggert@twinsun.com>
7072
7073 Change identifier spellings to avoid collisions with names
7074 that are reserved by POSIX.
7075
7076 Don't use names ending in _t, since POSIX reserves them.
7077 For consistency, remove _e and _s endings -- they're weren't
7078 needed to remove ambiguity. All uses changed.

7154 value_t_as_yystype -> value_as_yystype.
7155
7156 Don't include <errno.h> in the mainstream code, since it
7157 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
7158 * lib/get-errno.c, lib/get-errno.h: New files.
7159 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
7160 get-errno.c.
7161 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
7162 * src/output.c (output_skeleton): Likewise.
7163 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
7164 instead of errno.

7169 (TAB_EXT): Renamed from EXT_TAB.
7170 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
7171
7172 Avoid str[a-z]*, since <string.h> reserves that name space.
7173 Change all instances of "struniq" in names to "uniqstr", and
7174 likewise for "STRUNIQ" and "UNIQSTR".
7175 * src/uniqstr.c: Renamed from src/struniq.c.
7176 * src/uniqstr.h: Renamed from src/struniq.h.
7177 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

7200 (ACTION_MAX): Remove; unused.
7201 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
7202 Unnecessary casts removed from above defines.
7203
7204
7205 Fix misspelling in names.
7206 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
7207 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from

7212 for consistency with other names.
7213 * lib/timevar.h (timevar_report): New decl.
7214 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
7215
7216
7217 Sort include-file uses.
7218
7219 Reorder all include files under src to be in the order "system.h".
7220 then the ../lib include files in angle brackets (alphabetized),
7221 then the . include files in double-quotes (alphabetized). Fix
7222 dependency breakages encountered in this process, as follows:
7223 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
7224 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
7225 * src/state.h: Include "symtab.h".
7226
7227 2002-12-08 Paul Eggert <eggert@twinsun.com>
7228
7229 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
7230 since this causes problems when __file__ contains character
7231 sequences like "@" that are treated specially by src/scan-skel.l.
7232 Instead, just use the file's basename. This fixes the bug
7233 reported by Martin Mokrejs in
7234 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
7235
7236 2002-12-06 Paul Eggert <eggert@twinsun.com>
7237
7238 Add support for rules that do not have trailing semicolons, as
7239 POSIX requires. Improve the quality of locations in Bison
7240 diagnostics.
7241
7242 * src/location.c: Include <quotearg.h>.
7243 (empty_location): Now const.
7244 (location_print): New function. Follow the recommendation of the
7245 GNU Coding Standards for locations that span file boundaries.
7246 * src/location.h: Do not include <quotearg.h>; no longer needed.
7247 (boundary): New type.
7248 (location_t): Use it. This allows locations to span file boundaries.
7249 All member uses changed: file -> start.file or end.file (as needed),
7250 first_line -> start.line, first_column -> start.column,
7251 last_line -> end.line, last_column -> end.column.
7252 (equal_boundaries): New function.
7253 (LOCATION_RESET, LOCATION_STEP): Remove.
7254 (LOCATION_PRINT): Remove. All callers changed to use location_print.
7255 (empty_location): Now const.
7256 (location_print): New decl.
7257 * src/parse-gram.y (lloc_default): New function, which handles
7258 empty locations more accurately.
7259 (YYLLOC_DEFAULT): Use it.
7260 (%token COLON): Remove.
7261 (%token ID_COLON): New token.
7262 (rules): Use it.
7263 (declarations, rules): Remove trailing semicolon.
7264 (declaration, rules_or_grammar_declaration):
7265 Allow empty (";") declaration.
7266 (symbol_def): Remove empty actions; no longer needed.
7267 (rules_or_grammar_declaration): Remove trailing semicolon.
7268 (semi_colon.opt): Remove.
7269 * src/reader.h: Include location.h.
7270 (scanner_cursor): New decl.
7271 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
7272 rolling our own.
7273 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
7274 of *loc.
7275 (STEP): Remove. No longer needed, now that adjust_location does
7276 the work. All uses removed.
7277 (scanner_cursor): New var.
7278 (adjust_location): Renamed from extend_location. It now sets
7279 *loc and adjusts the scanner cursor. All uses changed.
7280 Don't bother testing for CR.
7281 (handle_syncline): Remove location arg; now updates scanner cursor.
7282 All callers changed.
7283 (unexpected_end_of_file): Now accepts start boundary of token or
7284 comment, not location. All callers changed. Update scanner cursor,
7285 not the location.
7286 (SC_AFTER_IDENTIFIER): New state.
7287 (context_state): Renamed from c_context. All uses changed.
7288 (id_loc, code_start, token_start): New local vars.
7289 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
7290 processing of Yacc white space and equivalents here.
7291 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
7292 instead of returning ID immediately, since we need to search for
7293 a subsequent colon.
7294 (<INITIAL>"'", "\""): Save token_start.
7295 (<INITIAL>"%{", "{", "%%"): Save code_start.
7296 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
7297 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
7298 BEGIN context_state at end, not INITIAL.
7299 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
7300 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
7301 Return correct token start.
7302 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
7303 the start of a character, string or multiline comment is found.
7304 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
7305 Reduction): Adjust reported locations to match the more-precise
7306 results now expected.
7307 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
7308 * tests/reduce.at (Useless Rules, Reduced Automaton,
7309 Underivable Rules): Likewise.
7310 * tests/regression.at (Invalid inputs): No longer `expecting ";"
7311 or "|"' now that so many other tokens are allowed by the new grammar.
7312
7313 * src/complain.h (current_file): Remove duplicate decl;
7314 current_file is now owned by files.h.
7315 * src/complain.c, src/scan-gram.l: Include files.h.
7316
7317 2002-12-06 Paul Eggert <eggert@twinsun.com>
7318
7319 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
7320 promotes to int; it might be unsigned int.
7321 * data/yacc.c (yy_reduce_print): Likewise.
7322
7323 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
7324 be #defined in the prologue, not in the Bison declarations.
7325 This fixes Debian Bug 102878, reported by Shaul Karl.
7326
7327 2002-12-02 Paul Eggert <eggert@twinsun.com>
7328
7329 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
7330 * lib/strtoul.c: New file, from gnulib.
7331 This fixes a porting bug reported by Peter Klein in
7332 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
7333
7334 2002-11-30 Paul Eggert <eggert@twinsun.com>
7335
7336 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
7337 and put only a forward declaration in the prologue. This is for
7338 consistency with the other scanner helper functions.
7339
7340 Type clashes now generate warnings, not errors, since it
7341 appears that POSIX may allow some grammars with type clashes.
7342 * src/reader.c (grammar_current_rule_check): Warn about
7343 type clashes instead of complaining.
7344 * tests/input.at (Type Clashes): Expect warnings, not complaints.
7345
7346 Add Yacc library, since POSIX requires it.
7347 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
7348 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
7349 * lib/main.c, lib/yyerror.c: New files.
7350
7351 gram_error can be static; it need not be extern.
7352 * src/reader.h (gram_error): Remove decl.
7353 * src/parse-gram.y (gram_error): Now static. Add static decl.
7354 (print_token_value): Omit parameter names from forward decl,
7355 for consistency.
7356
7357 2002-11-29 Paul Eggert <eggert@twinsun.com>
7358
7359 * doc/bison.texinfo: Emphasize that yylex and yyerror must
7360 be declared before being used. E.g., one should typically
7361 declare them in the prologue. Use GNU coding style in examples.
7362 Put "const" consistently after the type it modifies. Mention
7363 that C99 supports "inline". Mention that yyerror traditionally
7364 returns "int".
7365
7366 %parse-param and %lex-param now take just one argument, the
7367 declaration; the argument name is deduced from the declaration.
7368
7369 * doc/bison.texinfo (Parser Function, Pure Calling, Error
7370 Reporting, Table of Symbols): Document this.
7371 * src/parse-gram.y (add_param): New function.
7372 (COMMA): Remove.
7373 (declaration): Implement new rule for %parse-param and %lex-param.
7374 * src/scan-gram.l: "," now elicits a warning, rather than being
7375 a token; this is more compatible with byacc.
7376 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
7377
7378 2002-11-27 Paul Eggert <eggert@twinsun.com>
7379
7380 Rename identifiers to avoid real and potential collisions.
7381
7382 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
7383 to avoid collision with lex macro described by Bruce Lilly in
7384 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
7385 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
7386 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
7387 * src/parse-gram.y (print_token_value): Renamed from yyprint.
7388 All uses changed.
7389 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
7390 The name "yycontrol" violates the name space rules, and this stuff
7391 wasn't being used anyway.
7392 (input): Remove action; this stuff wasn't being used.
7393 (gram_error): Rename local variable yylloc -> loc.
7394 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
7395 (YY_DECL): Don't use "yy" at start of local variables.
7396 All uses changed, e.g., yylloc -> loc.
7397 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
7398 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
7399 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
7400 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
7401
7402 * src/parse-gram.y (gram_error): loc is now const *.
7403 * src/reader.h (gram_error): Likewise.
7404
7405 2002-11-24 Paul Eggert <eggert@twinsun.com>
7406
7407 Version 1.75c.
7408
7409 * tests/actions.at (Actions after errors): Use an output format
7410 more similar to that of the Printers and Destructors test.
7411 Test the position of the ';' token too.
7412 (Printers and Destructors): Likewise.
7413 (Printers and Destructors: %glr-parser): Remove for now, to avoid
7414 unnecessarily alarming people when the test fails.
7415
7416 * data/yacc.c (yyerrlab1): Move this label down, so that the
7417 parser does not discard the lookahead token if the user code
7418 invokes YYERROR. This change is required for POSIX conformance.
7419
7420 * lib/error.c: Sync with gnulib.
7421
7422 2002-11-22 Paul Eggert <eggert@twinsun.com>
7423
7424 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

7427
7428 2002-11-20 Paul Eggert <eggert@twinsun.com>
7429
7430 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
7431
7432 2002-11-20 Paul Eggert <eggert@twinsun.com>
7433
7434 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
7435 should use `if (! x) abort ();' rather than `assert (x);', and
7436 anyway it's one less thing to worry about configuring.
7437
7438 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
7439 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
7440 and replace all instances of assert with abort.
7441 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7442 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
7443
7444 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
7445 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
7446 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
7447 hash_find_entry, hash_rehash, hash_insert): Likewise.
7448 * src/conflicts.c (resolve_sr_conflict): Likewise.
7449 * src/lalr.c (set_goto_map, map_goto): Likewise.

7454 state_reduction_find): Likewise.
7455 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
7456 symbol_pack): Likewise.
7457 * src/tables.c (conflict_row, pack_vector): Likewise.
7458 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
7459 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
7460 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
7461 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
7462
7463 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
7464 (ARGMATCH_CONSTRAINT): New macro.
7465 (ARGMATCH_ASSERT): Use it.
7466
7467 * src/system.h (verify): New macro.
7468 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
7469 rather than assert.
7470 * src/tables.c (tables_generate): Likewise.
7471
7472 * src/struniq.c (struniq_assert): Now returns void, and aborts
7473 if the assertion is false.
7474 (struniq_assert_p): Remove.
7475 * src/struniq.h: Likewise.
7476
7477 2002-11-18 Paul Eggert <eggert@twinsun.com>

7479 * data/glr.c (yygetLRActions): Replace `yyindex' with
7480 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
7481 This fixes the regression with Sun ONE Studio 7 cc that I reported in
7482 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
7483
7484 2002-11-18 Akim Demaille <akim@epita.fr>
7485
7486 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
7487 space.
7488 From Tim Van Holder.
7489
7490 2002-11-17 Paul Eggert <eggert@twinsun.com>
7491
7492 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
7493 to "SyntaxError" for consistency with my 2002-11-15 change.
7494
7495 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
7496 not define to {}, since this breaks the common use of `YYDPRINTF
7497 ((...));' if a single statement is desired (e.g. before `else').
7498 Work around GCC warnings by surrounding corresponding calls with
7499 {} if needed.
7500 (yyhasResolvedValue): Remove unused function.
7501 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
7502 loop body.
7503 (yyreportSyntaxError): Renamed from yyreportParseError.
7504 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
7505 All uses changed.
7506 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
7507 extern when possible. Remove unused initializations.
7508
7509 2002-11-16 Akim Demaille <akim@epita.fr>
7510
7511 Augment the similarity between GLR and LALR traces.
7512
7513 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
7514 (YY_REDUCE_PRINT): New.
7515 (yyparse): Use them.
7516 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
7517 YYDPRINT here.
7518 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
7519 state reached after the reduction/recovery, since...
7520 (yyparse, yyprocessOneStack): Report the state we are entering in.
7521
7522 2002-11-16 Akim Demaille <akim@epita.fr>
7523
7524 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
7525 Add support for --trace=skeleton.
7526 * src/scan-skel.l: %option debug.
7527 Scan strings of non-@ or \n instead of character by character.
7528 (scan_skel): Handle trace_skeleton.
7529 (QPUTS): New.
7530 (@output_parser_name@, @output_header_name@): ``Restore'' their
7531 support (used to be M4 macros).
7532 * data/yacc.c: Quote larger chunks, a la glr.c.
7533 * data/lalr1.cc: Likewise.
7534 The header guards are no longer available, so use some other
7535 string than `YYLSP_NEEDED'.
7536
7537 2002-11-16 Akim Demaille <akim@epita.fr>
7538
7539 Make the ``Printers and Destructors'' test more verbose, taking
7540 `yacc.c''s behavior as (possibly wrong) reference.
7541
7542 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
7543 instead of fprint on stdout.
7544 Set and report the last_line of the symbols.
7545 Consistently display values and locations.
7546
7547 2002-11-16 Paul Eggert <eggert@twinsun.com>
7548
7549 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
7550
7551 2002-11-15 Paul Eggert <eggert@twinsun.com>
7552
7553 * tests/actions.at (Actions after errors): New test case.
7554
7555 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
7556 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
7557 tests/action.at, tests/calc.at, tests/conflicts.at,
7558 tests/cxx-type.at, tests/regression.at:
7559 "parse error" -> "syntax error" for POSIX compatibility.
7560 "parsing stack overflow..." -> "parser stack overflow" so
7561 that code matches Bison documentation.
7562
7563 2002-11-15 Akim Demaille <akim@epita.fr>
7564
7565 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
7566 take two BRACED_CODE, not two string_content.
7567 Free the scanner's obstack when we are done.
7568 (code_content): New.
7569 * tests/calc.at: Adjust.
7570 * doc/bison.texinfo: Adjust.
7571 Also, make sure to include the `,' for these declarations.
7572
7573 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
7574
7575 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
7576 definition; avoids potential autoreconf problems.
7577
7578 2002-11-15 Akim Demaille <akim@epita.fr>
7579
7580 Always check the value returned by yyparse.
7581
7582 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
7583 returned by yyparse.
7584 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
7585 Adjust calls.
7586 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
7587 returned by yyparse.
7588
7589 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
7590
7591 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
7592 on input.at test.
7593
7594 2002-11-14 Paul Eggert <eggert@twinsun.com>
7595
7596 * src/output.c (output_skeleton): Call xfopen instead of
7597 duplicating xfopen's body.
7598
7599 Fix bugs reported by Nelson H. F. Beebe in
7600 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
7601
7602 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
7603 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
7604 Group compiler. Instead, use "$CC -E bar.c". Include the .h
7605 file twice in the grammar, as an extra check.
7606
7607 * tests/input.at (Torturing the Scanner): Surround the
7608 backslash-newline tests with "#if 0", to make it less likely that
7609 we'll run into compiler bugs. Bring back solitary \ inside
7610 comment, but add a closing comment to work around HP C bug. Don't
7611 test backslash-newline in C character constant.
7612
7613 2002-11-14 Akim Demaille <akim@epita.fr>
7614
7615 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
7616 status of the compiler.
7617 Calling `exit 1' is no longer needed.
7618 Reported by Nelson H. F. Beebe.
7619
7620 2002-11-14 Akim Demaille <akim@epita.fr>
7621
7622 * tests/atlocal.in (CPPFLAGS): We have config.h.
7623 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
7624 New.
7625 * tests/actions.at, tests/calc.at, tests/conflicts.at,
7626 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
7627 * tests/regression.at, tests/torture.at: Use them for all the
7628 grammars that are to be compiled.
7629 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
7630 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
7631 * doc/bison.texinfo (GLR Parsers): Document `inline'.
7632
7633 2002-11-14 Akim Demaille <akim@epita.fr>
7634
7635 * doc/bison.texinfo: Various formatting changes (alignments in
7636 samples, additional @group/@end group, GCS in samples.
7637 Use @deffn instead of simple @table to define the directives,
7638 macros, variables etc.
7639
7640 2002-11-13 Paul Eggert <eggert@twinsun.com>
7641
7642 Fix some bugs reported by Albert Chin-A-Young in
7643 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
7644
7645 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
7646 -o c"; the HP C compiler chatters during compilation.
7647 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
7648 * tests/headers.at (export YYLTYPE): Likewise.
7649
7650 * tests/input.at (Torturing the Scanner): Remove lines containing
7651 solitary backslashes, as they tickle a bug in the HP C compiler.
7652
7653 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
7654 comments, since they're not portable. Use GNU coding style.
7655
7656 2002-11-13 Akim Demaille <akim@epita.fr>
7657
7658 * data/yacc.c: Leave bigger chunks of quoted text.
7659 (YYDSYMPRINTF): New.
7660 Use it to report symbol activities.
7661 * data/glr.c (YYDSYMPRINTF): New.
7662 Use it.
7663
7664 2002-11-12 Paul Eggert <eggert@twinsun.com>
7665
7666 Version 1.75b.
7667
7668 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
7669 (yyglrReduce): Return yyok, not 0.
7670 This should avoid the enumerated-type warnings reported
7671 by Nelson H. F. Beebe in
7672 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
7673
7674 * lib/bbitset.h (BITSET_INLINE): Remove.
7675 * lib/bitset.h [! BITSET_INLINE]: Remove.
7676 (bitset_set, bitset_reset, bitset_test): Rename local vars
7677 to avoid shadowing warnings by GCC.
7678
7679 * data/glr.c (inline): Remove #define. It's the user's
7680 responsibility to #define it away, just like 'const'.
7681 This fixes one of the bugs reported by Nelson H. F. Beebe in
7682 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
7683
7684 * Makefile.maint (po-check): Scan .l and .y files instead of the
7685 .c and the .h files that they generate. This fixes the bug
7686 reported by Tim Van Holder in:
7687 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
7688 Look for N_ as well as for _. Try to avoid matching #define for
7689 N_ and _.
7690 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
7691 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
7692 * src/scan-gram.l: Revamp regular expressions so that " and '
7693 do not confuse xgettext.
7694
7695 * src/struniq.h (struniq_new): Do not declare the return type
7696 to be 'const'; this violates the C standard.
7697 * src/struniq.c (struniq_new): Likewise.
7698
7699 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
7700
7701 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
7702 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
7703 linker.
7704
7705 2002-11-12 Akim Demaille <akim@epita.fr>
7706
7707 * Makefile.maint: Sync with Autoconf:
7708 (local_updates): New.
7709
7710 2002-11-12 Akim Demaille <akim@epita.fr>
7711
7712 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
7713

7715
7716 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
7717 locations.
7718
7719 2002-11-12 Akim Demaille <akim@epita.fr>
7720
7721 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
7722 not yyvalue.
7723
7724 2002-11-12 Akim Demaille <akim@epita.fr>
7725
7726 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
7727 Use it to test the GLR parser.
7728
7729 2002-11-12 Akim Demaille <akim@epita.fr>
7730
7731 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
7732 defines it.
7733 * data/glr.c (yystos): New.
7734 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
7735 (YYDSYMPRINT): New.

7737 (yyrecoverParseError): Free verbosely the discarded symbols.
7738 * data/yacc.c (yysymprint): Remove, rather...
7739 (b4_yysymprint_generate): invoke.
7740 * data/c.m4 (b4_yysymprint_generate): New.
7741 Accept pointers as arguments, as opposed to the version from
7742 yacc.c.
7743 (b4_yydestruct_generate): Likewise.
7744 * tests/cations.at (Printers and Destructors): Use Bison directives
7745 instead of CPP macros.
7746 Don't rely on internal details.
7747
7748 2002-11-12 Akim Demaille <akim@epita.fr>
7749
7750 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
7751 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
7752 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
7753 it against YYEMPTY and so forth), work on yytoken (i.e., set
7754 it to YYEMPTY etc.).
7755 (yydestruct): Replace with a b4_yydestruct_generate invocation.
7756 (b4_symbol_actions): Remove.
7757 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
7758 for 0, end-of-input.
7759
7760 2002-11-12 Akim Demaille <akim@epita.fr>
7761
7762 * doc/bison.texinfo (Destructor Decl): New.
7763
7764 2002-11-12 Akim Demaille <akim@epita.fr>
7765
7766 * src/tables.c (tables_generate): Use free for pointers that
7767 cannot be NULL, not XFREE.
7768 (pack_vector): Use assert, not fatal, for bound violations.

7770 * src/reader.c (reader): Likewise.
7771 * src/lalr.c (set_goto_map): Likewise.
7772 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
7773 the file name.
7774
7775 2002-11-12 Akim Demaille <akim@epita.fr>
7776
7777 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
7778 Restore.
7779 * src/scan-gram.l (last_string): Is global to the file, not to
7780 yylex.
7781 * src/parse-gram.y (input): Don't append the epilogue here,
7782 (epilogue.opt): do it here, and free the scanner's obstack.
7783 * src/reader.c (epilogue_set): Rename as...
7784 (epilogue_augment): this.
7785 * data/c.m4 (b4_epilogue): Defaults to empty.
7786
7787 2002-11-12 Akim Demaille <akim@epita.fr>
7788
7789 * src/getargs.c (long_options): Remove duplicates.

7794
7795 2002-11-12 Akim Demaille <akim@epita.fr>
7796

7798 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
7799
7800 Use struniq for symbols.
7801
7802 * src/symtab.h (symbol_t): The tag member is a struniq.
7803 (symbol_type_set): Adjust.
7804 * src/symtab.c (symbol_new): Takes a struniq.
7805 (symbol_free): Don't free the tag member.
7806 (hash_compare_symbol_t, hash_symbol_t): Rename as...

7827 file names.
7828 Don't free the input file name.
7829
7830 2002-11-12 Akim Demaille <akim@epita.fr>
7831
7832 * src/symtab.c (symbol_free): Remove dead deactivated code:
7833 type_name are properly removed.

7842
7843 2002-11-11 Paul Eggert <eggert@twinsun.com>
7844
7845 Revamp to fix many (but not all) of the C- and M4-related quoting
7846 problems. Among other things, this fixes the Bison bug reported
7847 by Jan Hubicka when processing the Bash grammar; see:
7848 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
7849
7850 Use new @ escapes consistently. Represent brackets with @{ and @}
7851 rather than @<:@ and @:>@, since this works a bit better with dumb
7852 editors like vi. Represent @ with @@, since @ is now consistently
7853 an escape. Use @oline@ and @ofile@ rather than __oline__ and
7854 __ofile__, to avoid unexpected expansions. Similarly, use @output
7855 rather than #output.
7856
7857 * data/c.m4 (b4_copyright): Omit file name from comment, since
7858 the file name could contain "*/".
7859 (b4_synclines_flag): Don't quote the 2nd argument; it should already
7860 be quoted. All uses changed.
7861
7862 * data/glr.c: Use new @ escapes consistently.
7863 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
7864 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
7865 Remove, since they couldn't handle arbitrary characters in file
7866 names.
7867 * data/lalr1.cc: Likewise.
7868 * data/yacc.c: Likewise.
7869
7870 * src/files.c (output_infix): Remove; all uses removed.
7871 * src/files.h: Likewise.
7872
7873 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
7874 mishandled funny characters in file names, and anyway it isn't
7875 needed any more.
7876 * data/yacc.c: Likewise.
7877 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
7878
7879 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
7880 * data/yacc.c: Likewise.
7881
7882 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
7883 strings now.
7884 (muscle_init): Quote filename as a C string.
7885 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
7886 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
7887 * src/output.c (escaped_file_name_output): New function.
7888 (prepare_symbols): Quote tokens for M4.
7889 (prepare): Don't insert output_infix, output_prefix,
7890 output_parser_name, output_header_name; this is now down by scan-skel.
7891 Insert skeleton as a C string.
7892
7893 * src/output.c (user_actions_output, symbol_destructors_output,
7894 symbol_printers_output): Quote filenames for C and M4.
7895 * src/reader.c (prologue_augment, epilogue_set): Likewise.
7896
7897 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
7898 escapes other than \\ and \'; this simplifies the code.
7899 (<SC_STRING>): Likewise, for \\ and \".
7900 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
7901 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
7902 Use new escapes @{ and @} for [ and ].
7903
7904 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
7905 them with auto vars.
7906 Switch to new escape scheme, where @ is the escape character uniformly.
7907 Abort if a stray escape character is found. Avoid unbounded input
7908 buffer when parsing non-escaped text.
7909
7910 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
7911 __oline__, #output, $@, and @{ do not have unintended meanings.
7912
7913 2002-11-09 Paul Eggert <eggert@twinsun.com>
7914
7915 Fix the test failure due to GCC warnings described in
7916 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
7917 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
7918 evaluate to 0 if it's impossible for NINF to be in the respective
7919 table.
7920 (yygetLRActions, yyrecoverParseError): Use them.
7921
7922 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
7923 counted in the token inserted at end of file. Now takes
7924 location_t *, not location_t, so that the location can be
7925 adjusted. All uses changed.
7926
7927 * tests/regression.at (Invalid inputs): Adjust wording in
7928 diagnostic to match the new behavior.
7929
7930 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
7931 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
7932 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
7933 abort ();'. This reduces the runtime of the "Many lookaheads"
7934 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
7935 GCC 3.2.
7936
7937 2002-11-07 Paul Eggert <eggert@twinsun.com>
7938
7939 * src/parse-gram.y (CHARACTER): Remove unused token.
7940 All uses removed.
7941
7942 * src/scan-gram.l: Remove stack option. We no longer use the
7943 stack, since the stack was never deeper than 1; instead, use the
7944 new auto var c_context to record the stacked value.
7945
7946 Remove nounput option. At an unexpected end of file, we now unput
7947 the minimal input necessary to end cleanly; this simplifies the
7948 code.
7949
7950 Avoid unbounded token sizes where this is easy.
7951
7952 (unexpected_end_of_file): New function.
7953 Use it to systematize the error message on unexpected EOF.
7954 (last-string): Now auto, not static.
7955 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
7956 (scanner_last_string_free): Remove; not used.
7957 (percent_percent_count): Move decl to just before use.
7958 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
7959 not the (never otherwised-used) CHARACTER.
7960
7961 2002-11-07 Akim Demaille <akim@epita.fr>
7962
7963 Let yyerror always receive the msg as last argument, so that
7964 yyerror can be variadic.
7965
7966 * data/yacc.c (b4_yyerror_args): New.
7967 Use it when calling yyerror.
7968 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
7969 Use it when calling yyerror.
7970 * doc/bison.texinfo (Error Reporting): Adjust.
7971 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
7972 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
7973
7974 2002-11-06 Akim Demaille <akim@epita.fr>
7975
7976 #line should have quoted strings.
7977 Ideally, this should be done by m4_quotearg.
7978
7979 * src/scan-skel.l: Include quotearg.h.
7980 Quote __ofile__.
7981 * src/output.c (symbol_printers_output)
7982 (symbol_destructors_output): Quote the file name.
7983
7984 2002-11-06 Akim Demaille <akim@epita.fr>
7985
7986 * tests/regression.at (Invalid inputs): Adjust to the recent
7987 messages.
7988
7989 2002-11-06 Akim Demaille <akim@epita.fr>
7990
7991 Restore --no-lines.
7992 Reported by Jim Kent.
7993
7994 * data/c.m4 (b4_syncline): New.
7995 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
7996 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
7997 * src/output.c (user_actions_output): Likewise.
7998 (prepare): Define 'b4_synclines_flag'.
7999 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
8000
8001 2002-11-06 Akim Demaille <akim@epita.fr>
8002
8003 * src/main.c (main): Free `infile'.
8004 * src/scan-gram.l (handle_syncline): New.
8005 Recognize `#line'.
8006 * src/output.c (user_actions_output, symbol_destructors_output)
8007 (symbol_printers_output): Use the location's file name, not
8008 infile.
8009 * src/reader.c (prologue_augment, epilogue_set): Likewise.
8010
8011 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8012
8013 * src/tables.c (matching_state): Don't allow states to match if
8014 either has GLR conflict entries.
8015
8016 2002-11-05 Paul Eggert <eggert@twinsun.com>
8017
8018 * src/scan-gram.l: Use more accurate diagnostics, e.g.
8019 "integer out of range" rather than "invalid value".
8020 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
8021 accordingly.
8022
8023 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
8024 Also, remove one static variable in the scanner.
8025
8026 * src/scan-gram.l (braces_level): Now auto, not static.
8027 Initialize to zero if the compiler is being picky.
8028 (INITIAL): Clear braces_level instead of incrementing it.
8029 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
8030 as POSIX 1003.1-2001 requires.
8031 * src/system.h (IF_LINT): New macro, taken from coreutils.
8032 * configure.ac: Define "lint" if --enable-gcc-warnings.
8033
8034 2002-11-05 Akim Demaille <akim@epita.fr>
8035
8036 * src/scan-gram.l: When it starts with `%', complain about the
8037 whole directive, not just that `invalid character: %'.
8038
8039 2002-11-04 Akim Demaille <akim@epita.fr>
8040
8041 * Makefile.maint: Update from Autoconf.
8042 (update, cvs-update, po-update, do-po-update): New.
8043
8044 2002-11-04 Akim Demaille <akim@epita.fr>
8045
8046 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
8047 and yyerror.
8048 Have yyerror `use' its arguments.
8049 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
8050 returns true when location & yacc & pure & parse-param.
8051 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
8052
8053 2002-11-04 Akim Demaille <akim@epita.fr>
8054
8055 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
8056 clashes.
8057 * src/scan-gram.l: Use [\'] instead of ['] to pacify
8058 font-lock-mode.
8059 Use complain_at.
8060 Use quote, not quote_n since LOCATION_PRINT no longer uses the
8061 slot 0.
8062
8063 2002-11-03 Paul Eggert <eggert@twinsun.com>
8064
8065 * src/reader.c (get_merge_function, grammar_current_rule_check):
8066 Use consistent diagnostics for reporting type name clashes.
8067 Quote the types with <>, for consistency with Yacc.
8068 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
8069
8070 2002-11-03 Akim Demaille <akim@epita.fr>
8071
8072 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
8073 New.
8074 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
8075 (b4_parse_param): Remove.
8076 Use b4_identification.
8077 Propagate b4_pure_args where needed to pass them to yyerror.
8078 * data/glr.m4 (b4_parse_param): Remove.
8079 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
8080 (b4_lpure_formals): New.
8081 Use b4_identification.
8082 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
8083 b4_user_formals and b4_user_args.
8084 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
8085 (yyreportAmbiguity): When using a pure parser, also need
8086 the location, and the parse-params.
8087 Adjust callers.
8088 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
8089 When using a pure parser, also need the parse-params.
8090 Adjust callers.
8091 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
8092 (%pure-parser + %parse-param) LALR and GLR parsers.
8093 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
8094 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
8095 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
8096 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
8097 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
8098 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
8099 * doc/bison.texinfo: Untabify the whole file.
8100 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
8101 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
8102 (Error Reporting): Adjust to these new directives.
8103 Document %error-verbose, deprecate YYERROR_VERBOSE.
8104
8105 2002-11-03 Akim Demaille <akim@epita.fr>
8106
8107 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
8108 AT_CHECK_CALC_GLR invocations to use % directives, instead of
8109 command line options.
8110 * tests/cxx-type.at: Formatting changes.
8111
8112 2002-11-03 Paul Eggert <eggert@twinsun.com>
8113
8114 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
8115 to count columns correctly, and to check for invalid inputs.
8116
8117 Use mbsnwidth to count columns correctly. Account for tabs, too.
8118 Include mbswidth.h.
8119 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
8120 (extend_location): New function.
8121 (YY_LINES): Remove.
8122
8123 Handle CRLF in C code rather than in Lex code.
8124 (YY_INPUT): New macro.
8125 (no_cr_read): New function.
8126
8127 Scan UCNs, even though we don't fully handle them yet.
8128 (convert_ucn_to_byte): New function.
8129
8130 Handle backslash-newline correctly in C code.
8131 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
8132 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
8133 all uses changed.
8134 (tag, splice): New EREs. Do not allow NUL or newline in tags.
8135 Use {splice} wherever C allows backslash-newline.
8136 YY_STEP after space, newline, vertical-tab.
8137 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
8138
8139 (letter, id): Don't assume ASCII; e.g., spell out a-z.
8140
8141 ({int}, handle_action_dollar, handle_action_at): Check for integer
8142 overflow.
8143
8144 (YY_STEP): Omit trailing semicolon, so that it's more like C.
8145
8146 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
8147 as well as \000. Check for UCHAR_MAX, not 255.
8148 Allow \x with an arbitrary positive number of digits, as in C.
8149 Check for overflow here.
8150 Allow \? and UCNs, for compatibility with C.
8151
8152 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
8153 with quote slot used by complain_at.
8154
8155 * tests/input.at: Add tests for backslash-newline, m4 quotes
8156 in symbols, long literals, and funny escapes in strings.
8157
8158 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
8159 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
8160 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
8161 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
8162 * m4/mbswidth.m4: New file, from GNU coreutils.
8163
8164 * doc/bison.texinfo (Grammar Outline): Document // comments.
8165 (Symbols): Document that trigraphs have no special meaning in Bison,
8166 nor is backslash-newline allowed.
8167 (Actions): Document that trigraphs have no special meaning.
8168
8169 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
8170 no longer used.
8171
8172 2002-11-02 Paul Eggert <eggert@twinsun.com>
8173
8174 * src/reader.c: Don't include quote.h; not needed.
8175 (get_merge_function): Reword warning to be consistent with
8176 type clash diagnostic in grammar_current_rule_check.
8177
8178 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
8179 bug in trigraph handling.
8180
8181 * src/output.c (prepare_symbols): When printing token names,
8182 escape "[" as "@<:@" and likewise for "]".
8183
8184 * src/system.h (errno): Remove declaration, as we are now
8185 assuming C89 or better, and C89 guarantees errno.
8186
8187 2002-10-30 Paul Eggert <eggert@twinsun.com>
8188
8189 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
8190 Check for close failures.
8191 * src/files.h (xfclose): Return void, not int, since it always
8192 returned zero.
8193 * src/files.c (xfclose): Likewise. Report I/O error if ferror
8194 indicates one.
8195 * src/output.c (output_skeleton): Use xfclose rather than fclose
8196 and ferror. xfclose now checks ferror.
8197
8198 * data/glr.c (YYLEFTMOST_STATE): Remove.
8199 (yyreportTree): Use a stack-based leftmost state. This avoids
8200 our continuing battles with bogus warnings about initializers.
8201
8202 2002-10-30 Akim Demaille <akim@epita.fr>
8203
8204 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
8205 #if.
8206
8207 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8208
8209 * tests/glr-regr1.at: New test for reported regressions.
8210 * tests/testsuite.at: Add glr-regr1.at test.
8211 * tests/Makefile.am: Add glr-regr1.at test.
8212
8213 2002-10-24 Paul Eggert <eggert@twinsun.com>
8214
8215 Version 1.75a.
8216
8217 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
8218 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
8219 we use malloc. Don't assume 'A' through 'Z' are contiguous.
8220 Don't assume strdup exists; POSIX says its an XSI extension.
8221 Check for buffer overflow on input.
8222
8223 2002-10-24 Akim Demaille <akim@epita.fr>
8224
8225 * src/output.c (output_skeleton): Don't disable M4sugar comments
8226 too soon: it results in comments being expanded.
8227 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
8228 first output.
8229
8230 2002-10-24 Akim Demaille <akim@epita.fr>
8231
8232 * data/yacc.c (m4_int_type): New.
8233 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
8234 char' as only yacc.c wants K&R portability.
8235 * data/glr.c (yysigned_char): Remove.
8236 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
8237 Reported by Quoc Peyrot.
8238
8239 2002-10-23 Paul Eggert <eggert@twinsun.com>
8240
8241 * src/main.c (main): With --trace=time, report times even if a
8242 non-fatal error occurs. Formerly, the times were reported in some
8243 such cases but not in others.
8244 * src/reader.c (reader): Just return if a complaint has been issued,
8245 instead of exiting, so that 'main' can report times.
8246
8247 2002-10-22 Akim Demaille <akim@epita.fr>
8248
8249 * src/system.h: Include sys/types.
8250 Reported by Bert Deknuydt.
8251
8252 2002-10-23 Paul Eggert <eggert@twinsun.com>
8253
8254 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
8255 Suggested by Art Haas.
8256
8257 2002-10-22 Paul Eggert <eggert@twinsun.com>
8258
8259 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
8260 decl; not needed any more.
8261 * src/main.c (main): Use return to exit, undoing yesterday's change.
8262 The last OS that we could find where this wouldn't work is
8263 SunOS 3.5, and that's too old to worry about now.
8264
8265 * data/glr.c (struct yyltype): Define members even when not
8266 doing locations. This is more consistent with yacc.c, and it
8267 works around the following bug reports:
8268 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
8269 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
8270
8271 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
8272 @acronym consistently. Standardize on "Yacc" instead of "YACC",
8273 "Algol" instead of "ALGOL". Give a bit more history about BNF.
8274
8275 2002-10-22 Akim Demaille <akim@epita.fr>
8276
8277 * data/README: New.
8278
8279 2002-10-21 Paul Eggert <eggert@twinsun.com>
8280
8281 Be consistent about 'bool'; the old code used an enum in one
8282 module and an int in another, and this violates the C standard.
8283 * m4/stdbool.m4: New file, from coreutils 4.5.3.
8284 * configure.ac (AC_HEADER_STDBOOL): Add.
8285 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
8286 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
8287 * src/symtab.c (hash_compare_symbol_t): Likewise.
8288 * src/system.h (bool, false, true): Use a definition consistent
8289 with ../lib/hash.c. All uses changed.
8290
8291 * src/complain.c (warning_issued): Renamed from warn_message_count,
8292 so that we needn't worry about integer overflow (!).
8293 Now of type bool. All uses changed.
8294 (complaint_issued): Renamed from complain_message_count; likewise.
8295
8296 * src/main.c (main): Use exit to exit with failure.
8297
8298 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
8299 rather than 1 and 0.
8300 * src/main.c (main): Likewise.
8301 * src/getargs.c (getargs): Likewise.
8302 * src/reader.c (reader): Likewise.
8303
8304 * src/getarg.c (getargs): Remove duplicate code for
8305 "Try `bison --help'".
8306
8307 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
8308 What was that "2" for?
8309
8310 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
8311 * src/getargs.c (usage): Likewise.
8312
8313 * src/getargs.c (getargs): When there are too few operands, report
8314 the last one. When there are too many, report the first extra
8315 one. This is how diffutils does it.
8316
8317 2002-10-20 Paul Eggert <eggert@twinsun.com>
8318
8319 Remove K&R vestiges.
8320 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
8321 * src/complain.c (VA_START): Remove. Assume prototypes.
8322 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
8323 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
8324 fatal): Assume prototypes.
8325 * src/complain.h: Assume prototypes.
8326 * src/system.h (PARAMS): Remove.
8327 Include <limits.h> unconditionally, since it's guaranteeed even
8328 for a freestanding C89 compiler.
8329 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
8330 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
8331

8341
8342 2002-10-20 Akim Demaille <akim@epita.fr>
8343
8344 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
8345 arguments and output `void'.
8346 (b4_c_function): Rename as...
8347 (b4_c_function_def): this.
8348 (b4_c_function_decl, b4_c_ansi_function_def)
8349 (b4_c_ansi_function_decl): New.
8350 Change the interpretation of the arguments: before `int, foo', now
8351 `int foo, foo'.
8352 * data/yacc.c (yyparse): Prototype and define thanks to these.
8353 Adjust b4_c_function_def uses.
8354 * data/glr.c (yyparse): Likewise, but ANSI only.
8355
8356 2002-10-20 Akim Demaille <akim@epita.fr>
8357
8358 * src/output.c (prepare): Move the definition of `tokens_number',
8359 `nterms_number', `undef_token_number', `user_token_number_max'
8360 to...
8361 (prepare_tokens): Here.

8369 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
8370
8371 2002-10-20 Akim Demaille <akim@epita.fr>
8372
8373 * src/tables.h, src/tables.c, src/output.c: Comment changes.
8374
8375 2002-10-20 Akim Demaille <akim@epita.fr>
8376
8377 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
8378 * data/c.m4: here.
8379
8380 2002-10-20 Akim Demaille <akim@epita.fr>

8382 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
8383 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
8384 `pair'.

8389 These.
8390
8391 2002-10-19 Paul Eggert <eggert@twinsun.com>
8392
8393 Do not create a temporary file, as that involves security and
8394 cleanup headaches. Instead, use a pair of pipes.
8395 Derived from a suggestion by Florian Krohm.
8396 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
8397 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
8398 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
8399 (BISON_PREREQ_SUBPIPE): Add.
8400 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
8401 Add subpipe.h, subpipe.c.
8402 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
8403 * po/POTFILES.in: Add lib/subpipe.c.
8404 * src/output.c: Include "subpipe.h".
8405 (m4_invoke): Remove decl.
8406 (scan_skel): New decl.
8407 (output_skeleton): Use pipe rather than temporary file for m4 input.
8408 Check that m4sugar.m4 is readable, to avoid deadlock.
8409 Check for pipe I/O error.
8410 * src/scan-skel.l (readpipe): Remove decl.
8411 (scan_skel): New function, to be used in place of m4_invoke.
8412 Read from stream rather than file.
8413
8414 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
8415 float, as this generates a warning on Solaris 8 + GCC 3.2 with
8416 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
8417 this generates a more-accurate value anyway.
8418
8419 * lib/timevar.c (timervar_accumulate): Rename locals to
8420 avoid confusion with similarly-named more-global.
8421 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
8422
8423 * src/output.c (prepare): Use xstrdup to convert char const *
8424 to char *, to avoid GCC warning.
8425
8426 2002-10-19 Akim Demaille <akim@epita.fr>
8427
8428 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
8429 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
8430 Use them to have `calc.y' ready for %pure-parser.
8431 * data/yacc.c (YYLEX): Pass a yylex return type to
8432 b4_c_function_call.
8433
8434 2002-10-19 Akim Demaille <akim@epita.fr>
8435
8436 Prototype support of %lex-param and %parse-param.
8437
8438 * src/parse-gram.y: Add the definition of the %lex-param and
8439 %parse-param tokens, plus their rules.
8440 Drop the `_' version of %glr-parser.
8441 Add the "," token.
8442 * src/scan-gram.l (INITIAL): Scan them.
8443 * src/muscle_tab.c: Comment changes.
8444 (muscle_insert, muscle_find): Rename `pair' as `probe'.
8445 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
8446 (muscle_entry_s): The `value' member is no longer const.
8447 Adjust all dependencies.
8448 * src/muscle_tab.c (muscle_init): Adjust: use
8449 MUSCLE_INSERT_STRING.
8450 Initialize the obstack earlier.
8451 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
8452 (muscle_pair_list_grow): New.
8453 * data/c.m4 (b4_c_function_call, b4_c_args): New.
8454 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
8455 * tests/calc.at: Use %locations, not --locations.
8456 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
8457
8458 2002-10-19 Akim Demaille <akim@epita.fr>
8459
8460 * src/getargs.c (usage): Take status as argument and exit
8461 accordingly.
8462 Report the traditional `Try ... --help' message when status != 0.
8463 (usage, version): Don't take a FILE * as arg, it is pointless.
8464 (getargs): When there is an incorrect number of arguments, make it
8465 an error, and report it GNUlically thanks to `usage ()'.
8466
8467 2002-10-18 Paul Eggert <eggert@twinsun.com>
8468
8469 * data/glr.c (yyreportParseError): Don't assume that sprintf
8470 yields the length of the printed string, as this is not true
8471 on SunOS 4.1.4. Reported by Peter Klein.
8472
8473 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
8474 * tests/conflicts.at (%nonassoc and eof): Likewise.
8475 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
8476
8477 2002-10-17 Akim Demaille <akim@epita.fr>
8478
8479 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
8480 * src/getargs.c (trace_types, trace_args): Adjust.
8481 * src/reader.c (grammar_current_rule_prec_set)
8482 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
8483 Standardize error messages.
8484 And s/@prec/%prec/!
8485 (reader): Use trace_flag to enable scanner/parser debugging,
8486 instead of an adhoc scheme.
8487 * src/scan-gram.l: Remove trailing debugging code.
8488
8489 2002-10-16 Paul Eggert <eggert@twinsun.com>
8490
8491 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
8492 MUSCLE_TAB_H.
8493
8494 * NEWS: Officially drop support for building Bison with K&R C,
8495 since it didn't work anyway and it's not worth worrying about.
8496 * Makefile.maint (wget_files): Remove ansi2knr.c.
8497 (ansi2knr.c-url_prefix): Remove.
8498 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
8499 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
8500 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
8501
8502 2002-10-15 Paul Eggert <eggert@twinsun.com>
8503
8504 Stop using the "enum_" trick for K&R-style function definitions;
8505 it confused me, and I was the author! Instead, assume that people
8506 who want to use K&R C compilers (when using these modules in GCC,
8507 perhaps?) will run ansi2knr.
8508
8509 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
8510 All uses of "enum_" changed to "enum ".
8511 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
8512 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
8513
8514 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

8521 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
8522 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
8523 Use function prototypes; this removes the need for declaring
8524 static functions simply to provide their prototypes.
8525 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

8580 Version 1.75.
8581
8582 2002-10-14 Akim Demaille <akim@epita.fr>
8583
8584 * tests/Makefile.am (maintainer-check-posix): New.
8585
8586 2002-10-14 Akim Demaille <akim@epita.fr>
8587
8588 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
8589 member.
8590
8591 2002-10-14 Akim Demaille <akim@epita.fr>
8592
8593 * src/tables.c (table_ninf_remap): base -> tab.
8594 Reported by Matt Rosing.
8595
8596 2002-10-14 Paul Eggert <eggert@twinsun.com>
8597
8598 * tests/action.at, tests/calc.at, tests/conflicts.at,
8599 tests/cxx-type.at, tests/headers.at, tests/input.at,
8600 tests/regression.at, tests/synclines.at, tests/torture.at:
8601 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
8602 so that the tests still work even if POSIXLY_CORRECT is set.
8603 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
8604
8605 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
8606 for portability to K&R hosts. Fix typo: signed char is guaranteed
8607 only to 127, not to 128.
8608 * data/glr.c (yysigned_char): New type.
8609 * data/yacc.c (yysigned_char): Likewise.
8610 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
8611
8612 2002-10-13 Paul Eggert <eggert@twinsun.com>
8613
8614 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
8615 true due to limited range of data type" warning from GCC.
8616
8617 * data/c.m4 (b4_token_defines): Protect against double-inclusion
8618 by wrapping enum yytokentype's definition inside #ifndef
8619 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
8620
8621 2002-10-13 Akim Demaille <akim@epita.fr>
8622
8623 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
8624 Un yy- yyrhs to avoid the name clash with the global YYRHS.
8625
8626 2002-10-13 Akim Demaille <akim@epita.fr>
8627
8628 * Makefile.maint: Update from Autoconf 2.54.
8629 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
8630
8631 2002-10-13 Akim Demaille <akim@epita.fr>
8632
8633 * src/print.c (print_state): Separate the list of solved conflicts
8634 from the other items.
8635 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
8636
8637 2002-10-13 Akim Demaille <akim@epita.fr>
8638
8639 Let nondeterministic skeletons be usable with deterministic
8640 tables.
8641
8642 With the patch, GAWK compiled by GCC without -O2 passes its test
8643 suite using a GLR parser driven by LALR tables. It fails with -O2
8644 because `struct stat' gives two different answers on my machine:
8645 88 (definition of an auto var) and later 96 (memset on this var).
8646 Hence the stack is badly corrumpted. The headers inclusion is to
8647 blame: if I move the awk.h inclusion before GLR's system header
8648 inclusion, the two struct stat have the same size.
8649
8650 * src/tables.c (pack_table): Always create conflict_table.
8651 (token_actions): Always create conflict_list.
8652 * data/glr.c (YYFLAG): Remove, unused.
8653
8654 2002-10-13 Akim Demaille <akim@epita.fr>
8655
8656 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
8657 (O0FLAGS): New.
8658 (VALGRIND, GXX): New.
8659 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
8660 * tests/bison.in: Run $PREBISON a pre-command.
8661 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
8662 (maintainer-check-g++): New.
8663 * Makefile.am (maintainer-check): New.
8664
8665 2002-10-13 Akim Demaille <akim@epita.fr>
8666
8667 * data/glr.c: Formatting changes.
8668 Tweak some trace messages to match yacc.c's.
8669
8670 2002-10-13 Akim Demaille <akim@epita.fr>
8671
8672 GLR parsers sometimes raise parse errors instead of performing the
8673 default reduction.
8674 Reported by Charles-Henry de Boysson.
8675
8676 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
8677 check the length of the traces when %glr.
8678 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
8679 GLR's traces.
8680 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
8681 Test GLR parsers.
8682 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
8683 (yyltype): Remove the yy prefix from the member names.
8684 (yytable): Complete its comment.
8685 (yygetLRActions): Map error action number from YYTABLE from
8686 YYTABLE_NINF to 0.
8687 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
8688 (which was a bug: it should have been YYTABEL_NINF, and yet it was
8689 not satisfying as we could compare an YYACTION computed from
8690 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
8691 only value for error actions.
8692 (yyreportParseError): In verbose parse error messages, don't issue
8693 `error' in the list of expected tokens.
8694 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
8695 next action to perform to match glr.c's decoding.
8696 (yytable): Complete its comment.
8697
8698 2002-10-13 Paul Eggert <eggert@twinsun.com>
8699
8700 Fix problem reported by Henrik Grubbstroem in
8701 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
8702 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
8703 because the Bison parser reads the second action before reducing
8704 the first one.
8705 * src/scan-gram.l (rule_length): New static var.
8706 Use it to keep track of the rule length in the scanner, since
8707 we can't expect the parser to be in lock-step sync with the scanner.
8708 (handle_action_dollar, handle_action_at): Use this var.
8709 * tests/actions.at (Exotic Dollars): Test for the problem.
8710
8711 2002-10-12 Paul Eggert <eggert@twinsun.com>
8712
8713 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
8714 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
8715 Include <sys/time.h> when checking for clock_t and struct tms.
8716 Use same include order as source.
8717 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
8718 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
8719
8720 * lib/timevar.c: Update copyright date and clarify comments.
8721 (get_time) [IN_GCC]: Keep the GCC version for reference.
8722
8723 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
8724 GCC version as of today, then merge Bison's changes.
8725 Change "GCC" to "Bison" in copyright notice. timevar.def's
8726 author is Akim, so change that too.
8727
8728 * src/reader.c (grammar_current_rule_check):
8729 Don't worry about the default action if $$ is untyped.
8730 Prevents bogus warnings reported by Jim Gifford in
8731 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.

8740
8741 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
8742 (yyparse): here. This undoes some of the 2002-07-25 change.

8756
8757 2002-10-10 Paul Eggert <eggert@twinsun.com>
8758
8759 Portability fixes for bitsets; this also avoids several GCC
8760 warnings.
8761
8762 * lib/abitset.c: Include <stddef.h>, for offsetof.
8763 * lib/lbitset.c: Likewise.
8764
8765 * lib/abitset.c (abitset_bytes): Return a size that is aligned
8766 properly for vectors of objects. Do not assume that adding a
8767 header size to a multiple of a word size yields a value that is
8768 properly aligned for the whole union.
8769 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8770
8771 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
8772 unique names for structures.
8773 * lib/ebitset.c (ebitset_bytes): Likewise.
8774 * lib/lbitset.c (lbitset_bytes): Likewise.
8775
8776 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
8777 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
8778 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
8779 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
8780 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
8781 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
8782 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
8783 to improve the type-checking that GCC can do.
8784 * lib/bitset.c (bitset_op4_cmp): Likewise.
8785 * lib/bitset_stats.c (bitset_stats_count,
8786 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
8787 bitset_stats_copy, bitset_stats_disjoint_p,
8788 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
8789 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
8790 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
8791 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
8792 bitset_stats_and_or_cmp, bitset_stats_andn_or,
8793 bitset_stats_andn_or_cmp, bitset_stats_or_and,
8794 bitset_stats_or_and_cmp): Likewise.
8795 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
8796 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
8797 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
8798 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
8799
8800 * lib/abitset.h: Include bitset.h, not bbitset.h.
8801 * lib/ebitset.h: Likewise.
8802 * lib/lbitset.h: Likewise.
8803
8804 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
8805 All instances of parameters of type enum bitset_opts are now of
8806 type enum_bitset_opts, to conform to the C Standard, and similarly
8807 for enum_bitset_type.
8808 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
8809 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
8810
8811 Do not use "struct bitset_struct" to mean different things in
8812 different modules. Not only is this confusing, it violates
8813 the C Standard, which requires that structure types in different
8814 modules must be compatible if one is to be passed to the other.
8815 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
8816 All instances of "struct bitset_struct *" replaced with "bitset".
8817 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
8818 (union bitset_union, struct abitset_struct, struct ebitset_struct,
8819 struct lbitset_struct, struct bitset_stats_struct): New types.
8820 All uses of struct bitset_struct changed to union bitset_union,
8821 etc.
8822 * lib/abitset.c (struct abitset_struct, abitset,
8823 struct bitset_struct): Remove.
8824 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
8825 struct bitset_struct): Remove.
8826 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
8827 bitset_struct): Remove.
8828 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
8829 Likewise.
8830
8831 Do not call a function of type T using a call that assumes the
8832 function is of a different type U. Standard C requires that a
8833 function must be called with a type that is compatible with its
8834 definition.
8835 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
8836 New decls.
8837 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
8838 New functions.
8839 * lib/ebitset.c (PFV): Remove.
8840 * lib/lbitset.c (PFV): Likewise.
8841 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
8842 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
8843 decls.
8844 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
8845 (ebitset_vtable): Use them.
8846 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
8847 lbitset_xor): New functions.
8848 (lbitset_vtable): Use them.
8849
8850 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
8851 Declare.
8852
8853 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
8854 GCC warning.
8855 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
8856 Use offsetof, for simplicity.
8857
8858 2002-10-06 Paul Eggert <eggert@twinsun.com>
8859
8860 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
8861 the same width as int. This reapplies a hunk of the 2002-08-12 patch
8862 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
8863 which was inadvertently undone by the 2002-09-30 patch.
8864 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
8865 the same width as int.
8866
8867 2002-10-04 Paul Eggert <eggert@twinsun.com>
8868
8869 Version 1.50.

8872
8873 * doc/bison.texinfo: Minor spelling, grammar, and white space
8874 fixes.
8875 (Symbols): Mention that any negative value returned from yylex
8876 signifies end-of-input. Warn about negative chars. Mention
8877 the portable Standard C character set.
8878
8879 The GNU coding standard says CFLAGS and YFLAGS are reserved
8880 for the installer to set.
8881 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
8882 * src/Makefile.am (AM_CFLAGS): Likewise.
8883 (AM_YFLAGS): Renamed from YFLAGS.
8884
8885 Fix some MAX and MIN problems.
8886 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
8887 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
8888 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
8889 * src/reader.c (reader): Use it.
8890
8891 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
8892 POSIX 1003.1-2001 has removed fgrep.
8893
8894 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
8895
8896 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
8897 interpreted as signed.
8898 * lib/ebitset.c (ebitset_list): Fix bug.
8899
8900 2002-10-01 Paul Eggert <eggert@twinsun.com>
8901
8902 More fixes for 64-bit hosts and large bitsets.
8903
8904 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
8905 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
8906 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
8907 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
8908 struct bitset_vtable.list, struct bitset_vtable.list_reverse,
8909 bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,

8927 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
8928 Use size_t, not unsigned int, to count bytes.
8929 * lib/abitset.h (abitset_bytes): Likewise.
8930 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
8931 Likewise.
8932 * lib/bitset.h (bitset_bytes): Likewise.
8933 * lib/bitset_stats.c (bitset_stats_bytes, bitset_stats_init): Likewise.

8945 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
8946 abitset_or_and, abitset_or_and_cmp):
8947 Use bitset_windex instead of unsigned int.
8948 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
8949 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
8950 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,
8951 ebitset_elt_find, ebitset_list_reverse, ebitset_list, ebitset_init):
8952 Likewise.
8953 * lib/lbitset.c (lbitset_ones, lbitset_not): Likewise.

8964 BITSET_SIZE_MAX): New macros.
8965 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
8966 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
8967 to BITSET_WINDEX_MAX.
8968
8969 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
8970 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
8971 since we now return the bitset_bindex type (not int).

9120 (yyreportParseError): Use size_t for yysize.
9121 (yy_yypstack): No longer nested inside yypstates, as nested
9122 functions are not portable. Do not assume size_t is the
9123 same width as int.
9124 (yypstates): Do not assume that ptrdiff_t is the same width
9125 as int, and similarly for yyposn and YYINDEX.
9126
9127 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
9128
9129 * lib/Makefile.am (INCLUDES): Do not include from the intl
9130 directory, which has been removed.
9131 * src/Makefile.am (INCLUDES): Likewise.

9165
9166 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
9167 PROTOTYPES to check for prototypes, and "defined __STDC__" to
9168 check for void *.
9169
9170 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
9171 size_t; the old version tried to do this but casted improperly.
9172 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
9173 (bitset_test): Now returns int, not unsigned long.
9174
9175 * lib/bitset_stats.c: Include "gettext.h".
9176 (_): New macro.
9177 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
9178 name locals "index", as it generates unnecessary warnings on some
9179 hosts that have an "index" function.

9181 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
9182 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

9203 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
9204 lib/timevar.c.
9205 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
9206 manual recommends.
9207 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
9208
9209 * src/complain.c (strerror_r): Remove decl; not needed.
9210 (strerror): Use same pattern as ../lib/error.c.
9211

9213
9214 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
9215
9216 * src/main.c (main): Cast result of bindtextdomain and textdomain
9217 to void, to avoid a GCC warning when --disable-nls is in effect.
9218
9219 * src/scan-gram.l: Use strings rather than escapes when possible,
9220 to minimize the number of warnings from xgettext.
9221 (handle_action_dollar, handle_action_at): Don't use isdigit,
9222 as it mishandles negative chars and it may not work as expected
9223 outside the C locale.
9224
9225 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
9226 this is a GCC extension and is not portable to other compilers.
9227
9228 * src/system.h (alloca): Use same pattern as ../lib/error.c.
9229 Do not include <ctype.h>; no longer needed.

9231 warnings on OpenBSD 3.0).
9232
9233 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
9234 it's not portable.
9235
9236 * tests/regression.at: Do not use 'cc -c input.c -o input';
9237 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
9238
9239 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
9240 exit status as failure, not just exit status 1. Sun C exits
9241 with status 2 sometimes.
9242
9243 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
9244 Use it for the two large tests.
9245
9246 2002-08-02 Akim Demaille <akim@epita.fr>
9247
9248 * src/conflicts.c (conflicts_output): Don't output rules never
9249 reduced here, since anyway that computation doesn't work.

9251 (rule_useless_p, rule_never_reduced_p): New.

9257 reduced to...
9258 (token_actions): here.
9259 * src/main.c (main): Make the parser before making the report, so
9260 that rules never reduced are computed.
9261 Call grammar_rules_never_reduced_report.
9262 * src/print.c (print_results): Report rules never reduced.
9263 * tests/conflicts.at, tests/reduce.at: Adjust.
9264
9265 2002-08-01 Akim Demaille <akim@epita.fr>
9266

9270 * src/state.h (state_t): Remove the `lookaheads',
9271 `lookaheads_rule' member.
9272 (reductions_t): Add a `lookaheads' member.
9273 Use a regular array for the `rules'.

9296 Adjust all dependencies.
9297 * src/nullable.c (set_nullable, free_nullable): Rename as...
9298 (nullable_compute, nullable_free): these.
9299 (rule_list_t): Store rule_t *, not rule_number_t.
9300 * src/state.c (state_rule_lookaheads_print): Directly compare rule
9301 pointers, instead of their numbers.
9302 * src/main.c (main): Call nullable_free, and derives_free earlier,
9303 as they were lo longer used.
9304
9305 2002-08-01 Akim Demaille <akim@epita.fr>
9306
9307 * lib/timevar.c (get_time): Include children time.
9308 * src/lalr.h (LA, LArule): Don't export them: used with the
9309 state_t.
9310 * src/lalr.c (LA, LArule): Static.

9314 table_size, not >.
9315 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
9316 (tables_generate): do it, since that's also it which allocates
9317 them.
9318 Don't free LA and LArule, main does.
9319
9320 2002-07-31 Akim Demaille <akim@epita.fr>

9356 * src/getargs.h, src/getargs.c: Support trace_time for
9357 --trace=time.
9358 * src/main.c (stage): Remove.
9359 (main): Replace `stage' invocations with timevar calls.
9360 * src/output.c: Insert pertinent timevar calls.

9365
9366 * src/getargs.h (enum trace_e): New.
9367 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.

9385 expected token.
9386 * tests/actions.at (Printers and Destructors): Adjust.
9387 * tests/calc.at (Calculator $1): Adjust.
9388 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
9389 error message, do not report the parser accepts the error token in
9390 that state.

9405 by conflicts.
9406
9407 * src/LR0.c (save_reductions): Don't make the final state too
9408 different: save its reduction (accept) instead of having a state
9409 without any action (no shift or goto, no reduce).
9410 Note: the final state is now a ``regular'' state, i.e., the
9411 parsers now contain `reduce 0' as default reduction.
9412 Nevertheless, since they decide to `accept' when yystate =
9413 final_state, they still will not reduce rule 0.
9414 * src/print.c (print_actions, print_reduction): Adjust.
9415 * src/output.c (action_row): Track reduced rules.
9416 (token_actions): Report rules never reduced.

9443 (endtoken, accept): these.
9444 * src/reader.c (reader): Set endtoken's default tag to "$end".
9445 Set undeftoken's tag to "$undefined" instead of "$undefined.".
9446 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
9447 Adjust.
9448
9449 2002-07-29 Akim Demaille <akim@epita.fr>
9450
9451 * src/reduce.c (reduce_grammar): When the language is empty,
9452 complain about the start symbol, not the axiom.
9453 Use its location.
9454 * tests/reduce.at (Empty Language): New.
9455
9456 2002-07-26 Akim Demaille <akim@epita.fr>
9457
9458 * src/reader.h, src/reader.c (gram_error): ... can't get
9459 yycontrol without making too strong assumptions on the parser
9460 itself.
9461 * src/output.c (prepare_tokens): Use the real 0th value of
9462 token_translations instead of `0'.
9463 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
9464 visible here.
9465 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
9466 for the time being: %locations ought to provide it to yyerror.
9467
9468 2002-07-25 Akim Demaille <akim@epita.fr>
9469
9470 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
9471 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
9472 * tests/regression.at (Web2c Actions): Adjust.
9473
9474 2002-07-25 Akim Demaille <akim@epita.fr>

9479 * src/nullable.c, src/output.c, src/print.c, src/reader.c
9480 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
9481 Iterate from 0 to nrules.
9482 Use rule_number_as_item_number and item_number_as_rule_number.
9483 Adjust to `derive' now containing possibly 0.
9484 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
9485 Handle the `- 1' part in rule numbers from/to item numbers.
9486 * src/conflicts.c (log_resolution): Fix the message which reversed
9487 shift and reduce.
9488 * src/output.c (action_row): Initialize default_rule to -1.

10607 prologue.

10629 2002-06-10 Akim Demaille <akim@epita.fr>
10630
10631 Remove `%thong' support as it is undocumented, unused, duplicates
10632 `%token's job, and creates useless e-mail traffic with people who
10633 want to know what it is, why it is undocumented, unused, and
10634 duplicates `%token's job.
10635
10636 * src/reader.c (parse_thong_decl): Remove.

10711

10853
10854 * src/LR0.c (new_state, get_state): Instead of using the global

11006 `rule_length', which is more readable.
11007 Adjust callers.
11008 (copy_at, copy_dollar): Instead of outputting the hard coded
11009 values of $$, $n and so forth, output invocation to b4_lhs_value,
11010 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
11011 Note: this patch partially drops `semantic-parser' support: it
11012 always does `rule_length - n', where semantic parsers ought to
11013 always use `-n'.
11014 * data/bison.simple, data/bison.c++ (b4_lhs_value)
11015 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

11042
11043 * src/scan-skel.l: Postprocess quadrigraphs.
11044
11045 * src/reader.c (copy_character): New function, used to output
11046 single characters while replacing `[' and `]' with quadrigraphs, to

11059 Reported by Paul Eggert.
11060
11061 2002-04-24 Robert Anisko <robert@lrde.epita.fr>
11062
11063 * tests/calc.at: Exercise prologue splitting.
11064
11065 * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
11066 `b4_post_prologue' instead of `b4_prologue'.

11069 muscles.
11070 (output): Free pre_prologue_obstack and post_prologue_obstack.

11072 (pre_prologue_obstack, post_prologue_obstack): New.
11073 * src/reader.c (copy_definition): Add a parameter to specify the
11074 obstack to fill, instead of using attrs_obstack unconditionally.
11075 (read_declarations): Pass pre_prologue_obstack to copy_definition if
11076 `%union' has not yet been seen, pass post_prologue_obstack otherwise.
11077

11079
11080 * data/bison.simple: Remove unnecessary commentary and white
11081 space differences from 1_29-branch.
11082 Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
11083
11084 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
11085 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
11086 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
11087 constructors or destructors.
11088
11089 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
11090
11091 2002-04-23 Akim Demaille <akim@epita.fr>

11116 * tests/regression.at (Web2c Actions): Adjust.
11117
11118 2002-04-22 Akim Demaille <akim@epita.fr>
11119
11120 * src/reader.c (token_translations_init): 256 is now the default
11121 value for the error token, i.e., it will be assigned another
11122 number if the user assigned 256 to one of her tokens.
11123 (reader): Don't force 256 to error.
11124 * doc/bison.texinfo (Symbols): Adjust.
11125 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
11126 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
11127 etc. instead of 10, 20, 30 (which was used to `jump' over error

11129
11130 2002-04-22 Akim Demaille <akim@epita.fr>
11131
11132 Propagate more token_number_t.
11133

11135 (item_number_as_token_number): New.
11136 * src/output.c (GENERATE_OUTPUT_TABLE): New.
11137 Use it to create output_item_number_table and

11147
11148 2002-04-19 Akim Demaille <akim@epita.fr>
11149
11150 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
11151 as Lex/Flex'.
11152 (Debugging): More details about enabling the debugging features.
11153 (Table of Symbols): Describe $$, $n, @$, and @n.
11154 Suggested by Tim Josling.
11155
11156 2002-04-19 Akim Demaille <akim@epita.fr>
11157
11158 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
11159
11160 2002-04-10 Akim Demaille <akim@epita.fr>

11164
11165 2002-04-09 Akim Demaille <akim@epita.fr>
11166
11167 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
11168 full stderr, and strip it according to the bison options, instead
11169 of composing the error message from different bits.
11170 This makes it easier to check for several error messages.
11171 Adjust all the invocations.
11172 Add an invocation exercising the error token.
11173 Add an invocation demonstrating a stupid error message.
11174 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
11175 Adjust the tests.
11176 Error message are for stderr, not stdout.
11177
11178 2002-04-09 Akim Demaille <akim@epita.fr>
11179
11180 * src/gram.h, src/gram.c (error_token_number): Remove, use
11181 errtoken->number.
11182 * src/reader.c (reader): Don't specify the user token number (2)
11183 for $undefined, as it uselessly prevents using it.
11184 * src/gram.h (token_number_t): Move to...
11185 * src/symtab.h: here.
11186 (state_t.number): Is a token_number_t.
11187 * src/print.c, src/reader.c: Use undeftoken->number instead of
11188 hard coded 2.
11189 (Even though this 2 is not the same as above: the number of the
11190 undeftoken remains being 2, it is its user token number which
11191 might not be 2).
11192 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
11193 `user_token_number_max'.
11194 Output `undef_token_number'.
11195 * data/bison.simple, data/bison.c++: Use them.
11196 Be sure to map invalid yylex return values to
11197 `undef_token_number'. This saves us from gratuitous SEGV.

11209 Use __ofile__.
11210 * data/bison.simple: Use __ofile__.
11211 * src/scan-skel.l: Handle __ofile__.

11214
11215 * src/gram.h (item_number_t): New, the type of item numbers in
11216 RITEM. Note that it must be able to code symbol numbers as
11217 positive number, and the negation of rule numbers as negative
11218 numbers.
11219 Adjust all dependencies (pretty many).
11220 * src/reduce.c (rule): Remove this `short *' pointer: use
11221 item_number_t.
11222 * src/system.h (MINSHORT, MAXSHORT): Remove.
11223 Include `limits.h'.
11224 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
11225 (shortcpy): Remove.
11226 (MAXTABLE): Move to...
11227 * src/output.c (MAXTABLE): here.
11228 (prepare_rules): Use output_int_table to output rhs.

11444
11445 * data/bison.c++, data/bison.simple: Don't output the current file

11646 * src/lalr.h, src/lalr.c (tokensetsize): Remove, unused.
11647 * src/system.h (BITS_PER_WORD, WORDSIZE, SETBIT, RESETBIT, BITISSET):
11648 Ditto.
11649
11650 2002-03-04 Akim Demaille <akim@epita.fr>
11651
11652 * src/lalr.c (F): Now a bitset*.

11662 * src/L0.c, src/LR0.h (nstates): Be size_t.
11663 Adjust comparisons (signed vs unsigned).

11699 notice in each output file.
11700
11701 2002-02-28 Akim Demaille <akim@epita.fr>
11702
11703 * data/bison.c++: Copy the prologue of bison.simple to fetch
11704 useful M4 definitions, such as b4_header_guard.
11705
11706 2002-02-25 Akim Demaille <akim@epita.fr>
11707
11708 * src/getargs.c (version): Give the name of the authors, and use a
11709 translator friendly scheme for the bgr
11710 copyright notice.
11711
11712 2002-02-25 Akim Demaille <akim@epita.fr>
11713
11714 * src/output.c (header_output): Remove, now handled completely via
11715 M4.
11716
11717 2002-02-25 Akim Demaille <akim@epita.fr>
11718
11719 * m4/m4.m4: New, from CVS Autoconf.
11720 * configure.in: Invoke it.
11721 * src/output.c (output_skeleton): Use its result instead of the
11722 hard coded name.
11723
11724 2002-02-25 Akim Demaille <akim@epita.fr>
11725
11726 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
11727 Fileutils 4.1.5.
11728 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
11729 * src/output.c (output_skeleton): Use mkstemp to create a real
11730 temporary file.
11731 Move the filling of `skeleton' and its muscle to...
11732 (prepare): here.
11733 (output): Move the definition of the prologue muscle to...
11734 (prepare): here.
11735 * src/system.h (DEFAULT_TMPDIR): New.
11736
11737 2002-02-14 Paul Eggert <eggert@twinsun.com>
11738
11739 Remove the support for C++ namespace cleanliness; it was
11740 causing more problems than it was curing, since it didn't work
11741 properly on some nonstandard C++ compilers. This can wait
11742 for a proper C++ parser.
11743
11744 * NEWS: Document this.
11745 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
11746 of C++, as it's treated like C now.
11747 * src/bison.simple (YYSTD): Remove.
11748 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
11749 Treat C++ just like Standard C instead of trying to support
11750 namespace cleanliness.
11751
11752 2002-02-14 Akim Demaille <akim@epita.fr>
11753
11754 * tests/regression.at (else): Adjust to Andreas' change.

11756 2002-02-14 Akim Demaille <akim@epita.fr>
11757
11758 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
11759
11760 2002-02-13 Andreas Schwab <schwab@suse.de>
11761
11762 * src/output.c (output_rule_data): Don't output NULL, it might
11763 not be defined yet.
11764
11765 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
11766
11767 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.

11769
11770 2002-02-11 Akim Demaille <akim@epita.fr>
11771
11772 * tests/regression.at (%nonassoc and eof): Don't include
11773 nonportable headers.
11774
11775 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
11776
11777 * data/bison.c++: Correct error recovery. Make the user able to
11778 initialize the starting location.
11779
11780 2002-02-07 Akim Demaille <akim@epita.fr>
11781
11782 * tests/input.at: New.
11783
11784 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11785
11786 * data/bison.c++: Replace some direct m4 expansions by constants. Be
11787 more consistent when naming methods and variables. Put preprocessor
11788 directives around tables only needed for debugging.
11789
11790 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11791
11792 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
11793 C++ parsers.
11794 (yy::b4_name::parse): Use print_.
11795
11796 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11797

11805
11806 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
11807
11808 * data/bison.c++: Fix m4 quoting in comments.
11809
11810 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
11811

11813 not expanded by m4.
11814
11815 2002-02-05 Akim Demaille <akim@epita.fr>
11816
11817 * data/bison.c++: Adjust to the M4 back end.
11818 More is certainly needed.
11819
11820 2002-02-05 Akim Demaille <akim@epita.fr>
11821
11822 Give a try to M4 as a back end.
11823
11824 * lib/readpipe.c: New, from wdiff.
11825 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
11826 BISON_HAIRY.
11827 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
11828 specific values. Now it is m4 that performs the lookup.
11829 * src/parse-skel.y: Remove.
11830 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
11831 * src/output.c (actions_output, guards_output)
11832 (token_definitions_output): No longer keeps track of the output
11833 line number, hence remove the second argument.
11834 (guards_output): Check against the guard member of a rule, not the
11835 action member.
11836 Adjust callers.
11837 (output_skeleton): Don't look for the skeleton location, let m4 do
11838 that.
11839 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
11840 file will be used.
11841 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
11842 (prepare): Given that for the time being changesyntax is not
11843 usable in M4, rename the muscles using `-' to `_'.
11844 Define `defines_flag', `output_parser_name' and `output_header_name'.
11845 * src/output.h (actions_output, guards_output)
11846 (token_definitions_output): Adjust prototypes.
11847 * src/scan-skel.l: Instead of scanning the skeletons, it now
11848 processes the output of m4: `__oline__' and `#output'.
11849 * data/bison.simple: Adjust to be used by M4(sugar).
11850 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
11851 to date.
11852 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
11853 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
11854 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
11855 shamelessly stolen from CVS Autoconf.
11856
11857 2002-02-05 Akim Demaille <akim@epita.fr>
11858
11859 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
11860 * configure.in: Check for the declarations of free and malloc.
11861 * src/muscle_tab.c: Adjust.
11862
11863 2002-02-05 Akim Demaille <akim@epita.fr>
11864
11865 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
11866 which have no values.
11867
11868 2002-02-05 Akim Demaille <akim@epita.fr>
11869
11870 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
11871 * data/: here.
11872
11873 2002-01-29 Paul Eggert <eggert@twinsun.com>
11874
11875 * src/bison.simple (YYSIZE_T): Do not define merely because
11876 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
11877 On some platforms, <alloca.h> does not declare YYSTD (size_t).
11878
11879 2002-01-27 Akim Demaille <akim@epita.fr>
11880
11881 Fix `%nonassoc and eof'.
11882
11883 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
11884 which were not properly copied! Replace
11885 memcpy (res->errs, src->errs, src->nerrs);
11886 with
11887 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
11888 !!!
11889 * tests/regression.at (%nonassoc and eof): Adjust to newest
11890 Autotest: `.' is not in the PATH.
11891
11892 2002-01-27 Akim Demaille <akim@epita.fr>
11893
11894 * tests/sets.at (AT_EXTRACT_SETS): New.
11895 (Nullable): Use it.
11896 (Firsts): New.
11897
11898 2002-01-26 Akim Demaille <akim@epita.fr>
11899
11900 * tests/actions.at, tests/calc.at, tests/headers.at,
11901 * tests/torture.at: Adjust to the newest Autotest which no longer
11902 forces `.' in the PATH.
11903
11904 2002-01-25 Akim Demaille <akim@epita.fr>
11905
11906 * tests/regression.at (%nonassoc and eof): New.
11907 Suggested by Robert Anisko.
11908
11909 2002-01-24 Akim Demaille <akim@epita.fr>
11910
11911 Bison dumps core when trying to complain about broken input files.
11912 Reported by Cris van Pelt.
11913
11914 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
11915 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
11916 into...
11917 (Invalid inputs): Strengthen: exercise parse_percent_token.
11918
11919 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
11920
11921 * src/Makefile.am: Add bison.c++.
11922 * src/bison.c++: New skeleton.
11923
11924 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
11925
11926 * po/it.po: New.
11927
11928 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
11929
11930 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
11931
11932 2002-01-20 Marc Autret <marc@gnu.org>
11933
11934 * src/files.c (compute_output_file_names): Fix
11935
11936 2002-01-20 Marc Autret <marc@gnu.org>
11937
11938 * tests/output.at: New test.
11939 * src/files.c (compute_base_names): Don't map extensions when
11940 the YACC flag is set, use defaults.
11941 Reported by Evgeny Stambulchik.
11942
11943 2002-01-20 Marc Autret <marc@gnu.org>
11944
11945 * src/system.h: Need to define __attribute__ away for non-GCC
11946 compilers as well (i.e., the vendor C compiler).
11947 Suggested by Albert Chin-A-Young.
11948
11949 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
11950
11951 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
11952 canonical definition.
11953 * src/system.h: Use the canonical definition for PARAMS (avoids
11954 a conflict with the macro from lib/hash.h).
11955
11956 2002-01-11 Akim Demaille <akim@epita.fr>
11957
11958 * configure.in: Use AC_FUNC_STRNLEN.
11959 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
11960
11961 2002-01-09 Akim Demaille <akim@epita.fr>
11962
11963 * src/files.c, src/files.h (output_infix): New.
11964 (tab_extension): Remove.
11965 (compute_base_names): Compute the former, drop the latter.
11966 * src/output.c (prepare): Insert the muscles `output-infix', and
11967 `output-suffix'.
11968 * src/parse-skel.y (string, string.1): New.
11969 (section.header): Use it.
11970 (section.yacc): Remove.
11971 (prefix): Remove too.
11972 * src/scan-skel.l: Adjust.
11973 * src/bison.simple, src/bison.hairy: Adjust.
11974
11975 2002-01-09 Akim Demaille <akim@epita.fr>
11976
11977 * configure.in (WERROR_CFLAGS): Compute it.
11978 * src/Makefile.am (CFLAGS): Pass it.
11979 * tests/atlocal.in (CFLAGS): Idem.
11980 * src/files.c: Fix a few warnings.
11981 (get_extension_index): Remove, unused.
11982
11983 2002-01-08 Akim Demaille <akim@epita.fr>
11984
11985 * src/getargs.c (AS_FILE_NAME): New.
11986 (getargs): Use it to convert DOSish file names.
11987 * src/files.c (base_name): Rename as full_base_name to avoid
11988 clashes with `base_name ()'.
11989 (filename_split): New.
11990 (compute_base_names): N-th rewrite, using filename_split.
11991
11992 2002-01-08 Akim Demaille <akim@epita.fr>
11993
11994 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
11995 New, stolen from the Fileutils 4.1.
11996 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
11997 * configure.in: Check for the presence of memrchr, and of its
11998 prototype.
11999
12000 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
12001
12002 * lib/hash.h (__P): Added definition for this macro.
12003 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
12004 BUILT_SOURCES, to ensure they are generated first.
12005 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
12006 %error-verbose to allow bootstrapping with bison 1.30x.
12007
12008 2002-01-06 Akim Demaille <akim@epita.fr>
12009
12010 * src/reader.c (parse_braces): Don't fetch the next char, the
12011 convention is to fetch on entry.
12012 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
12013 'switch' without a following semicolon.
12014 * tests/regression.at (braces parsing): New.
12015
12016 2002-01-06 Akim Demaille <akim@epita.fr>
12017
12018 Bison is dead wrong in its RR conflict reports.
12019
12020 * tests/torture.at (GNU Cim Grammar): New.
12021 * src/conflicts.c (count_rr_conflicts): Fix.
12022
12023 2002-01-06 Akim Demaille <akim@epita.fr>
12024
12025 Creating package.m4 from configure.ac causes too many problems.
12026
12027 * tests/Makefile.am (package.m4): Create it by hand,
12028 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
12029
12030 2002-01-06 Akim Demaille <akim@epita.fr>
12031
12032 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
12033 skeleton.h.
12034
12035 2002-01-04 Paul Eggert <eggert@twinsun.com>
12036
12037 * doc/bison.texinfo (Debugging):
12038 Remove YYSTDERR; it's no longer defined or used.
12039 Also, s/cstdio.h/cstdio/.
12040
12041 2002-01-03 Akim Demaille <akim@epita.fr>
12042
12043 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
12044
12045 2002-01-03 Akim Demaille <akim@epita.fr>
12046
12047 * src/parse-skel.y (process_skeleton): Don't bind the parser's
12048 tracing code to --trace, wait for a better --trace option, with
12049 args.
12050
12051 2002-01-03 Akim Demaille <akim@epita.fr>
12052
12053 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
12054 The ISO C++ standard is extremely clear about it: stderr is
12055 considered a macro, not a regular symbol (see table 94 `Header
12056 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
12057 Therefore std:: does not apply to it. It still does with fprintf.
12058 Also, s/cstdio.h/cstdio/.
12059
12060 2002-01-03 Akim Demaille <akim@epita.fr>
12061
12062 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
12063 for non system headers.
12064
12065 2002-01-02 Akim Demaille <akim@epita.fr>
12066
12067 Equip the skeleton chain with location tracking, runtime trace,
12068 pure parser and scanner.
12069
12070 * src/parse-skel.y: Request a pure parser, locations, and prefix
12071 renaming.
12072 (%union): Having several members with the same type does not help
12073 type mismatches, simplify.
12074 (YYPRINT, yyprint): New.
12075 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
12076 (skel_error): this.
12077 Handle locations.
12078 * src/scan-skel.l: Adjust to these changes.
12079 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
12080 (LOCATION_PRINT, skel_control_t): New.
12081
12082 2001-12-30 Akim Demaille <akim@epita.fr>
12083
12084 * src/parse-skel.y: Get rid of the shift/reduce conflict:
12085 replace `gb' with BLANKS.
12086 * src/scan-skel.l: Adjust.
12087
12088 2001-12-30 Akim Demaille <akim@epita.fr>
12089
12090 * src/system.h: We don't need nor want bcopy.
12091 Throw away MS-DOS crap: we don't need getpid.
12092 * configure.in: We don't need strndup. It was even causing
12093 problems: because Flex includes the headers *before* us,
12094 _GNU_SOURCE is not defined by config.h, and therefore strndup was
12095 not visible.
12096 * lib/xstrndup.c: New.
12097 * src/scan-skel.l: Use it.
12098 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
12099 * src/parse-skel.y: Use %directives instead of #defines.
12100
12101 2001-12-30 Akim Demaille <akim@epita.fr>
12102
12103 * src/skeleton.h: New.
12104 * src/output.c (output_parser, output_master_parser): Remove, dead
12105 code.
12106 * src/output.h (get_lines_number, actions_output, guards_output)
12107 (token_definitions_output): Prototype them.
12108 * src/parse-skel.y: Add the license notice.
12109 Include output.h and skeleton.h.
12110 (process_skeleton): Returns void, and takes a single parameter.
12111 * src/scan-skel.l: Add the license notice.
12112 Include skeleton.h.
12113 Don't use %option yylineno: it seems that then Flex imagines
12114 REJECT has been used, and therefore it won't reallocate its
12115 buffers (which makes no other sense to me than a bug). It results
12116 in warnings for `unused: yy_flex_realloc'.
12117
12118 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
12119
12120 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
12121 (MUSCLE_INSERT_PREFIX): ...to there.
12122 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
12123 (MUSCLE_INSERT_PREFIX): Move from here...
12124
12125 * src/bison.hairy: Add a section directive. Put braces around muscle
12126 names. This parser skeleton is still broken, but Bison should not
12127 choke on a bad muscle 'syntax'.
12128 * src/bison.simple: Add a section directive. Put braces around muscle
12129 names.
12130
12131 * src/files.h (strsuffix, stringappend): Add declarations.
12132 (tab_extension): Add declaration.
12133 (short_base_name): Add declaration.
12134
12135 * src/files.c (strsuffix, stringappend): No longer static. These
12136 functions are used in the skeleton parser.
12137 (tab_extension): New.
12138 (compute_base_names): Use the computations done in this function
12139 to guess if the generated parsers should have '.tab' in their
12140 names.
12141 (short_base_name): No longer static.
12142
12143 * src/output.c (output_skeleton): New.
12144 (output): Disable call to output_master_parser, and give a try to
12145 a new skeleton handling system.
12146 (guards_output, actions_output): No longer static.
12147 (token_definitions_output, get_lines_number): No longer static.
12148
12149 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
12150
12151 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
12152 parse-skel.y.
12153
12154 * src/parse-skel.y: New file.
12155 * src/scan-skel.l: New file.
12156
12157 2001-12-29 Akim Demaille <akim@epita.fr>
12158
12159 %name-prefix is broken.
12160
12161 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
12162 Adjust all dependencies.
12163 * tests/headers.at (export YYLTYPE): Strengthen this test: use
12164 %name-prefix.
12165
12166 Renaming yylval but not yylloc is not consistent. Now we do.
12167
12168 * src/bison.simple: Prefix yylloc if used.
12169 * doc/bison.texinfo (Decl Summary): Document that.
12170
12171 2001-12-29 Akim Demaille <akim@epita.fr>
12172
12173 * doc/bison.texinfo: Promote `%long-directive' over
12174 `%long_directive'.
12175 Remove all references to fixed-output-files, yacc is enough.
12176
12177 2001-12-29 Akim Demaille <akim@epita.fr>
12178
12179 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
12180 user prologue. These are defaults.
12181 * tests/actions.at (Mid-rule actions): Make sure the user can
12182 define YYDEBUG and YYERROR_VERBOSE.
12183
12184 2001-12-29 Akim Demaille <akim@epita.fr>
12185
12186 * src/output.c (header_output): Don't forget to export YYLTYPE and
12187 yylloc.
12188 * tests/headers.at (export YYLTYPE): New, make sure it does.
12189 * tests/regression.at (%union and --defines, Invalid CPP headers):
12190 Move to...
12191 * tests/headers.at: here.
12192
12193 2001-12-29 Akim Demaille <akim@epita.fr>
12194
12195 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
12196
12197 2001-12-29 Akim Demaille <akim@epita.fr>
12198
12199 * tests/actions.at (Mid-rule actions): Output on a single line
12200 instead of several.
12201
12202 2001-12-29 Akim Demaille <akim@epita.fr>
12203
12204 * doc/bison.texinfo: Formatting changes.
12205
12206 2001-12-29 Akim Demaille <akim@epita.fr>
12207
12208 Don't store the token defs in a muscle, just be ready to output it
12209 on command. Now possible via `symbols'. Fixes a memory leak.
12210
12211 * src/output.c (token_definitions_output): New.
12212 (output_parser, header_output): Use it.
12213 * src/reader.c (symbols_save): Remove.
12214
12215 2001-12-29 Akim Demaille <akim@epita.fr>
12216
12217 * src/bison.simple: Do not provide a default for YYSTYPE and
12218 YYLTYPE before the user's prologue. Otherwise it's hardly... a
12219 default.
12220
12221 2001-12-29 Akim Demaille <akim@epita.fr>
12222
12223 Mid-rule actions are simply... ignored!
12224
12225 * src/reader.c (readgram): Be sure to attach mid-rule actions to
12226 the empty-rule associated to the dummy symbol, not to the host
12227 rule.
12228 * tests/actions.at (Mid-rule actions): New.
12229
12230 2001-12-29 Akim Demaille <akim@epita.fr>
12231
12232 Memory leak.
12233
12234 * src/reader.c (reader): Free grammar.
12235
12236 2001-12-29 Akim Demaille <akim@epita.fr>
12237
12238 Memory leak.
12239
12240 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
12241 since it allocates it for each state, although only one is needed.
12242 (allocate_storage): Do it here.
12243
12244 2001-12-29 Akim Demaille <akim@epita.fr>
12245
12246 * src/options.h, src/options.c (create_long_option_table): Rename
12247 as...
12248 (long_option_table_new): this, with a clearer prototype.
12249 (percent_table): Remove, unused,
12250 * src/getargs.c (getargs): Adjust.
12251
12252 2001-12-29 Akim Demaille <akim@epita.fr>
12253
12254 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
12255 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
12256 as states.
12257
12258 2001-12-29 Akim Demaille <akim@epita.fr>
12259
12260 * src/lalr.c (build_relations): Rename `states' as `states1'.
12261 Sorry, I don't understand exactly what it is, no better name...
12262
12263 2001-12-29 Akim Demaille <akim@epita.fr>
12264
12265 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
12266 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
12267 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
12268 as rules.
12269
12270 2001-12-29 Akim Demaille <akim@epita.fr>
12271
12272 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
12273 ago.
12274
12275 2001-12-29 Akim Demaille <akim@epita.fr>
12276
12277 * src/reader.c, src/reader.h (user_toknums): Remove.
12278 Adjust all users to use symbols[i]->user_token_number.
12279
12280 2001-12-29 Akim Demaille <akim@epita.fr>
12281
12282 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
12283 Adjust all users to use symbols[i]->prec or ->assoc.
12284
12285 2001-12-29 Akim Demaille <akim@epita.fr>
12286
12287 * src/reader.c, src/reader.h (tags): Remove.
12288 Adjust all users to use symbols[i]->tag.
12289
12290 2001-12-29 Akim Demaille <akim@epita.fr>
12291
12292 * src/gram.h, src/gram.c (symbols): New, similar to state_table
12293 and rule_table.
12294 * src/reader.c (packsymbols): Fill this table.
12295 Drop sprec.
12296 * src/conflicts.c (resolve_sr_conflict): Adjust.
12297 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
12298 single table.
12299 Use symbols[i]->tag instead of tags[i].
12300
12301 2001-12-29 Akim Demaille <akim@epita.fr>
12302
12303 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
12304 In addition, put a comment in there, to replace...
12305 * tests/regression.at (%union and C comments): Remove.
12306
12307 2001-12-29 Akim Demaille <akim@epita.fr>
12308
12309 * tests/regression.at (Web2c Actions): Blindly move the actual
12310 output as expected output. The contents *seem* right to me, but I
12311 can't pretend reading perfectly parser tables... Nonetheless, all
12312 the other tests pass correctly, the table look OK, even though the
12313 presence of `$axiom' is to be noted: AFAICS it is useless (but
12314 harmless).
12315
12316 2001-12-29 Akim Demaille <akim@epita.fr>
12317
12318 * src/reader.c (readgram): Don't add the rule 0 if there were no
12319 rules read. In other words, add it _after_ having performed
12320 grammar sanity checks.
12321 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
12322
12323 2001-12-29 Akim Demaille <akim@epita.fr>
12324
12325 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
12326 visible, and some states have now a different number.
12327
12328 2001-12-29 Akim Demaille <akim@epita.fr>
12329
12330 * src/reader.c (readgram): Bind the initial rule's lineno to that
12331 of the first rule.
12332 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
12333 (Solved SR Conflicts): Adjust rule 0's line number.
12334
12335 2001-12-29 Akim Demaille <akim@epita.fr>
12336
12337 Fix the `GAWK Grammar' failure.
12338
12339 * src/LR0.c (final_state): Initialize to -1 so that we do compute
12340 the reductions of the first state which was mistakenly confused
12341 with the final state because precisely final_state was initialized
12342 to 0.
12343 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
12344 now noticed by Bison.
12345 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
12346 have a reduction on $default.
12347
12348 2001-12-29 Akim Demaille <akim@epita.fr>
12349
12350 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
12351 rule line numbers.
12352 * src/closure.c (print_closure): Likewise.
12353 * src/derives.c (print_derives): Likewise.
12354 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
12355 now.
12356
12357 2001-12-29 Akim Demaille <akim@epita.fr>
12358
12359 * src/lalr.c (lookaheads_print): New.
12360 (lalr): Call it when --trace-flag.
12361 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
12362 are dumped.
12363
12364 2001-12-29 Akim Demaille <akim@epita.fr>
12365
12366 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
12367 when walking through ritem, even via rule->rhs.
12368 * src/reduce.c (dump_grammar, useful_production, reduce_output)
12369 (useful_production, useless_nonterminals): Likewise.
12370 (reduce_grammar_tables): Likewise, plus update nritems.
12371 * src/nullable.c (set_nullable): Likewise.
12372 * src/lalr.c (build_relations): Likewise.
12373 * tests/sets.at (Nullable): Adjust.
12374 Fortunately, now, the $axiom is no longer nullable.
12375
12376 2001-12-29 Akim Demaille <akim@epita.fr>
12377
12378 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
12379 the 0-sentinel.
12380 * src/gram.c (ritem_longest_rhs): Likewise.
12381 * src/reduce.c (nonterminals_reduce): Likewise.
12382 * src/print_graph.c (print_graph): Likewise.
12383 * src/output.c (output_rule_data): Likewise.
12384 * src/nullable.c (set_nullable): Likewise.
12385
12386 2001-12-29 Akim Demaille <akim@epita.fr>
12387
12388 * src/output.c: Comment changes.
12389
12390 2001-12-27 Paul Eggert <eggert@twinsun.com>
12391
12392 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
12393 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
12394 Sparc, as they were causing more porting problems than the
12395 (minor) performance improvement was worth.
12396
12397 Also, catch up with 1.31's YYSTD.
12398
12399 2001-12-27 Akim Demaille <akim@epita.fr>
12400
12401 * src/output.c (output_gram): Rely on nritems, not the
12402 0-sentinel. See below.
12403 Use -1 as separator, not 0.
12404 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
12405 Rely on -1 as separator in yyrhs, instead of 0.
12406 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
12407 twice `Now at end of input', therefore there are two lines less to
12408 expect.
12409
12410 2001-12-27 Akim Demaille <akim@epita.fr>
12411
12412 * tests/regression.at (Unresolved SR Conflicts):
12413 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
12414 below.
12415
12416 2001-12-27 Akim Demaille <akim@epita.fr>
12417
12418 * src/LR0.c (new_state): Recognize the final state by the fact it
12419 is reached by eoftoken.
12420 (insert_start_shifting_state, insert_eof_shifting_state)
12421 (insert_accepting_state, augment_automaton): Remove, since now
12422 these states are automatically computed from the initial state.
12423 (generate_states): Adjust.
12424 * src/print.c: When reporting a rule number to the user, substract
12425 1, so that the axiom rule is rule 0, and the first user rule is 1.
12426 * src/reduce.c: Likewise.
12427 * src/print_graph.c (print_core): For the time being, just as for
12428 the report, depend upon --trace-flags to dump the full set of
12429 items.
12430 * src/reader.c (readgram): Once the grammar read, insert the rule
12431 0: `$axiom: START-SYMBOL $'.
12432 * tests/set.at: Adjust: rule 0 is now displayed, and since the
12433 number of the states has changed (the final state is no longer
12434 necessarily the last), catch up.
12435
12436 2001-12-27 Akim Demaille <akim@epita.fr>
12437
12438 Try to make the use of the eoftoken valid. Given that its value
12439 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
12440 is used instead of > 0 where appropriate, (ii), depend upon nritems
12441 instead of the 0-sentinel.
12442
12443 * src/gram.h, src/gram.c (nritems): New.
12444 Expected to be duplication of nitems, but for the time being...
12445 * src/reader.c (packgram): Assert nritems and nitems are equal.
12446 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
12447 * src/closure.c (print_closure, print_fderives): Likewise.
12448 * src/gram.c (ritem_print): Likewise.
12449 * src/print.c (print_core, print_grammar): Likewise.
12450 * src/print_graph.c: Likewise.
12451
12452 2001-12-27 Akim Demaille <akim@epita.fr>
12453
12454 * src/main.c (main): If there are complains after grammar
12455 reductions, then output the report anyway if requested, then die.
12456 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
12457 * src/reader.c (eoftoken): New.
12458 (parse_token_decl): If the token being defined has value `0', it
12459 is the eoftoken.
12460 (packsymbols): No longer hack `tags' to insert `$' by hand.
12461 Be sure to preserve the value of the eoftoken.
12462 (reader): Make sure eoftoken is defined.
12463 Initialize nsyms to 0: now eoftoken is created just like the others.
12464 * src/print.c (print_grammar): Don't special case the eof token.
12465 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
12466 lie anyway, albeit pleasant.
12467 * tests/calc.at: Exercise error messages with eoftoken.
12468 Change the grammar so that empty input is invalid.
12469 Adjust expectations.
12470 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
12471
12472 2001-12-27 Akim Demaille <akim@epita.fr>
12473
12474 * configure.in: Check the protos of strchr ans strspn.
12475 Replace strchr if needed.
12476 * src/system.h: Provide the protos of strchr, strspn and memchr if
12477 missing.
12478 * lib/strchr.c: New.
12479 * src/reader.c (symbols_save): Use strchr.
12480
12481 2001-12-27 Akim Demaille <akim@epita.fr>
12482
12483 * src/print.c, src/print_graph.c (escape): New.
12484 Use it to quote the TAGS outputs.
12485 * src/print_graph.c (print_state): Now errors are in red, and
12486 reductions in green.
12487 Prefer high to wide: output the state number on a line of its own.
12488
12489 2001-12-27 Akim Demaille <akim@epita.fr>
12490
12491 * src/state.h, src/state.c (reductions_new): New.
12492 * src/LR0.c (set_state_table): Let all the states have a
12493 `reductions', even if reduced to 0.
12494 (save_reductions): Adjust.
12495 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
12496 * src/print.c (print_reductions, print_actions): Adjust.
12497 * src/output.c (action_row): Adjust.
12498
12499 2001-12-27 Akim Demaille <akim@epita.fr>
12500
12501 * src/state.h, src/state.c (errs_new, errs_dup): New.
12502 * src/LR0.c (set_state_table): Let all the states have an errs,
12503 even if reduced to 0.
12504 * src/print.c (print_errs, print_reductions): Adjust.
12505 * src/output.c (output_actions, action_row): Adjust.
12506 * src/conflicts.c (resolve_sr_conflict): Adjust.
12507
12508 2001-12-27 Akim Demaille <akim@epita.fr>
12509
12510 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
12511
12512 2001-12-27 Akim Demaille <akim@epita.fr>
12513
12514 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
12515 * src/print.c: here.
12516 (lookaheadset, shiftset): New, used as additional storage by
12517 print_reductions.
12518 (print_results): Adjust.
12519 (print_shifts, print_gotos, print_errs): New, extracted from...
12520 (print_actions): here.
12521 * src/print_graph.c (print_actions): Remove dead code.
12522
12523 2001-12-27 Akim Demaille <akim@epita.fr>
12524
12525 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
12526 `$n' and `@n'.
12527
12528 2001-12-27 Akim Demaille <akim@epita.fr>
12529
12530 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
12531 (build_relations): Adjust.
12532
12533 2001-12-27 Akim Demaille <akim@epita.fr>
12534
12535 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
12536 duplication.
12537
12538 2001-12-27 Akim Demaille <akim@epita.fr>
12539
12540 * src/reader.c (packgram): Catch nitems overflows.
12541
12542 2001-12-27 Akim Demaille <akim@epita.fr>
12543
12544 * src/files.c, src/files.h (guard_obstack): Remove.
12545 * src/output.c (output): Adjust.
12546 * src/reader.c (parse_braces): New, factoring...
12547 (copy_action, copy_guard): these two which are renamed as...
12548 (parse_action, parse_guard): these.
12549 As a voluntary consequence, using braces around guards is now
12550 mandatory.
12551
12552 2001-12-27 Akim Demaille <akim@epita.fr>
12553
12554 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
12555 * src/reader.c (symbol_list): `guard' and `guard_line' are new
12556 members.
12557 (symbol_list_new): Adjust.
12558 (copy_action): action_line is the first line, not the last.
12559 (copy_guard): Just as for actions, store the `action' only, not
12560 the switch/case/break flesh.
12561 Don't parse the user action that might follow the guard, let...
12562 (readgram): do it, i.e., now, there can be an action after a
12563 guard.
12564 In other words the guard is just explicitly optional.
12565 (packgram): Adjust.
12566 * src/output.c (guards_output): New.
12567 (output_parser): Call it when needed.
12568 (output): Also free the guard and attrs obstacks.
12569 * src/files.c, src/files.h (obstack_save): Remove.
12570 (output_files): Remove.
12571 As a result, if one needs the former `.act' file, using an
12572 appropriate skeleton which requires actions and guards is now
12573 required.
12574 * src/main.c (main): Adjust.
12575 * tests/semantic.at: New.
12576 * tests/regression.at: Use `input.y' as input file name.
12577 Avoid 8+3 problems by requiring input.c when the test needs the
12578 parser.
12579
12580 2001-12-27 Akim Demaille <akim@epita.fr>
12581
12582 * src/reader.c (symbol_list_new): Be sure to initialize all the
12583 fields.
12584
12585 2001-12-27 Akim Demaille <akim@epita.fr>
12586
12587 All the hacks using a final pseudo state are now useless.
12588
12589 * src/LR0.c (set_state_table): state_table holds exactly nstates.
12590 * src/lalr.c (nLA): New.
12591 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
12592 instead of lookaheadsp from the pseudo state (nstate + 1).
12593
12594 2001-12-27 Akim Demaille <akim@epita.fr>
12595
12596 * src/output.c (action_row, token_actions): Use a state_t instead
12597 of a integer, and nlookaheads instead of the following state's
12598 lookaheadsp.
12599
12600 2001-12-27 Akim Demaille <akim@epita.fr>
12601
12602 * src/conflicts.c (log_resolution, flush_shift)
12603 (resolve_sr_conflict, set_conflicts, solve_conflicts)
12604 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
12605 (conflicts_print, print_reductions): Use a state_t instead of an
12606 integer when referring to a state.
12607 As much as possible, depend upon nlookaheads, instead of the
12608 `lookaheadsp' member of the following state (since lookaheads of
12609 successive states are successive, the difference between state n + 1
12610 and n served as the number of lookaheads for state n).
12611 * src/lalr.c (add_lookback_edge): Likewise.
12612 * src/print.c (print_core, print_actions, print_state)
12613 (print_results): Likewise.
12614 * src/print_graph.c (print_core, print_actions, print_state)
12615 (print_graph): Likewise.
12616 * src/conflicts.h: Adjust.
12617
12618 2001-12-27 Akim Demaille <akim@epita.fr>
12619
12620 * src/bison.hairy: Formatting/comment changes.
12621 ANSIfy.
12622 Remove `register' indications.
12623 Add plenty of `static'.
12624
12625 2001-12-27 Akim Demaille <akim@epita.fr>
12626
12627 * src/output.c (prepare): Drop the muscle `ntbase' which
12628 duplicates ntokens.
12629 * src/bison.simple: Formatting/comment changes.
12630 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
12631 is an undocumented synonym.
12632
12633 2001-12-22 Akim Demaille <akim@epita.fr>
12634
12635 * src/output.c (output_table_data): Change the prototype to use
12636 `int' for array ranges: some invocations do pass an int, not a
12637 short.
12638 Reported by Wayne Green.
12639
12640 2001-12-22 Akim Demaille <akim@epita.fr>
12641
12642 Some actions of web2c.y are improperly triggered.
12643 Reported by Mike Castle.
12644
12645 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
12646 * tests/regression.at (Web2c): Rename as...
12647 (Web2c Report): this.
12648 (Web2c Actions): New.
12649
12650 2001-12-22 Akim Demaille <akim@epita.fr>
12651
12652 Reductions in web2c.y are improperly reported.
12653 Reported by Mike Castle.
12654
12655 * src/conflicts.c (print_reductions): Fix.
12656 * tests/regression.at (Web2c): New.
12657
12658 2001-12-18 Akim Demaille <akim@epita.fr>
12659
12660 Some host fail on `assert (!"foo")', which expands to
12661 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
12662 Reported by Nelson Beebee.
12663
12664 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
12665 `#define it_succeeded 0' and `assert (it_succeeded)'.
12666
12667 2001-12-17 Marc Autret <autret_m@epita.fr>
12668
12669 * src/bison.simple: Don't hard code the skeleton line and filename.
12670 * src/output.c (output_parser): Rename 'line' as 'output_line'.
12671 New line counter 'skeleton_line' (skeleton-line muscle).
12672
12673 2001-12-17 Paul Eggert <eggert@twinsun.com>
12674
12675 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
12676 YYDEBUG must be defined to a nonzero value.
12677
12678 * src/bison.simple (yytname): Do not assume that the user defines
12679 YYDEBUG to a properly parenthesized expression.
12680
12681 2001-12-17 Akim Demaille <akim@epita.fr>
12682
12683 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
12684 nlookaheads is a new member.
12685 Adjust all users.
12686 * src/lalr.h (nlookaheads): Remove this orphan declaration.
12687 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
12688 state.
12689
12690 2001-12-17 Akim Demaille <akim@epita.fr>
12691
12692 * src/files.h, src/files.c (open_files, close_files): Remove.
12693 * src/main.c (main): Don't open/close files, nor invoke lex_free,
12694 let...
12695 * src/reader.c (reader): Do it.
12696
12697 2001-12-17 Akim Demaille <akim@epita.fr>
12698
12699 * src/conflicts.c (print_reductions): Formatting changes.
12700
12701 2001-12-17 Akim Demaille <akim@epita.fr>
12702
12703 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
12704 (flush_reduce): New.
12705 (resolve_sr_conflict): Adjust.
12706
12707 2001-12-17 Akim Demaille <akim@epita.fr>
12708
12709 * src/output.c (output_obstack): Be static and rename as...
12710 (format_obstack): this, to avoid any confusion with files.c's
12711 output_obstack.
12712 * src/reader.h (muscle_obstack): Move to...
12713 * src/output.h: here, since it's defined in output.c.
12714
12715 2001-12-17 Akim Demaille <akim@epita.fr>
12716
12717 * src/output.c (action_row, save_column, default_goto)
12718 (sort_actions, matching_state, pack_vector): Better variable
12719 locality.
12720
12721 2001-12-17 Akim Demaille <akim@epita.fr>
12722
12723 * src/output.c: Various formatting changes.
12724
12725 2001-12-17 Akim Demaille <akim@epita.fr>
12726
12727 * src/files.c (output_files): Free the output_obstack.
12728 * src/main.c (main): Call print and print_graph conditionally.
12729 * src/print.c (print): Work unconditionally.
12730 * src/print_graph.c (print_graph): Work unconditionally.
12731 * src/conflicts.c (log_resolution): Output only if verbose_flag.
12732
12733 2001-12-16 Marc Autret <autret_m@epita.fr>
12734
12735 * src/output.c (actions_output): Fix. When we use %no-lines,
12736 there is one less line per action.
12737
12738 2001-12-16 Marc Autret <autret_m@epita.fr>
12739
12740 * src/bison.simple: Remove a useless #line directive.
12741 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
12742 * src/output.c (get_lines_number): New.
12743 (output_parser): Adjust, now takes care about the lines of a
12744 output muscles.
12745 Fix line numbering.
12746 (actions_output): Computes the number of lines taken by actions.
12747 (output_master_parser): Insert new skeleton which is the name of
12748 the output parser file name.
12749
12750 2001-12-15 Marc Autret <autret_m@epita.fr>
12751
12752 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
12753
12754 2001-12-15 Marc Autret <autret_m@epita.fr>
12755
12756 * src/output.c (output_gram): Keep track of the hairy one.
12757
12758 2001-12-15 Akim Demaille <akim@epita.fr>
12759
12760 Make `make distcheck' work.
12761
12762 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
12763 system.h which uses libgettext.h.
12764
12765 2001-12-15 Akim Demaille <akim@epita.fr>
12766
12767 * src/nullable.c (set_nullable): Useless rules must be skipped,
12768 otherwise, since we range over their symbols, we might look at a
12769 nonterminal which no longer ``exists'', i.e., it is not counted in
12770 `nvars', hence we overflow our arrays.
12771
12772 2001-12-15 Akim Demaille <akim@epita.fr>
12773
12774 The header can also be produced directly, without any obstack!
12775 Yahoo!
12776
12777 * src/files.c, src/files.h (defines_obstack): Remove.
12778 (compute_header_macro): Global.
12779 (defines_obstack_save): Remove.
12780 * src/reader.c (parse_union_decl): No longer output to
12781 defines_obstack: its content can be found in the `stype' muscle
12782 anyway.
12783 (output_token_translations): Merge into...
12784 (symbols_output): this.
12785 Rename as...
12786 (symbols_save): this.
12787 (reader): Adjust.
12788 * src/output.c (header_output): New.
12789 (output): Call it.
12790
12791 2001-12-15 Akim Demaille <akim@epita.fr>
12792
12793 * src/reader.c (parse_union_decl): Instead of handling two obstack
12794 simultaneously, use one to define the `stype' muscle, and use the
12795 value of the latter to fill defines_obstack.
12796 (copy_comment): Remove.
12797 (copy_comment2): Work for a single obstack.
12798 Rename as...
12799 (copy_comment): this.
12800
12801 2001-12-15 Akim Demaille <akim@epita.fr>
12802
12803 * src/lex.c, src/lex.h (xgetc): No longer static.
12804 * src/reader.c (parse_union_decl): Revamp.
12805
12806 2001-12-15 Akim Demaille <akim@epita.fr>
12807
12808 Still making progress in separating Bison into (i) input, (ii)
12809 process, (iii) output: now we can directly output the parser file
12810 without using table_obstack at all.
12811
12812 * src/files.c, src/files.h (table_obstack): Bye bye.
12813 (parser_file_name): New.
12814 * src/files.c (compute_output_file_names): Compute it.
12815 * src/output.c (actions_output, output_parser)
12816 (output_master_parser): To a file instead of an obstack.
12817
12818 2001-12-15 Akim Demaille <akim@epita.fr>
12819
12820 Attach actions to rules, instead of pre-outputting them to
12821 actions_obstack.
12822
12823 * src/gram.h (rule_t): action and action_line are new members.
12824 * src/reader.c (symbol_list): Likewise.
12825 (copy_action): Save the actions within the rule.
12826 (packgram): Save them in rule_table.
12827 * src/output.c (actions_output): New.
12828 (output_parser): Use it on `%%actions'.
12829 (output_rule_data): Don't free rule_table.
12830 (output): Do it.
12831 (prepare): Don't save the `action' muscle.
12832 * src/bison.simple: s/%%action/%%actions/.
12833
12834 2001-12-15 Akim Demaille <akim@epita.fr>
12835
12836 * src/reader.c (copy_action): When --yacc, don't append a `;'
12837 to the user action: let it fail if lacking.
12838 Suggested by Arnold Robbins and Tom Tromey.
12839
12840 2001-12-14 Akim Demaille <akim@epita.fr>
12841
12842 * src/lex.c (literalchar): Simply return the char you decoded, non
12843 longer mess around with obstacks and int pointers.
12844 Adjust all callers.
12845
12846 2001-12-14 Akim Demaille <akim@epita.fr>
12847
12848 * src/lex.c (literalchar): Don't escape the special characters,
12849 just decode them, and keep them as char (before, eol was output as
12850 the 2 char string `\n' etc.).
12851 * src/output.c (output_rule_data): Use quotearg to output the
12852 token strings.
12853
12854 2001-12-13 Paul Eggert <eggert@twinsun.com>
12855
12856 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
12857 Do not infringe on the global user namespace when using C++.
12858 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
12859 All uses of `fprintf' and `stderr' changed.
12860
12861 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
12862
12863 2001-12-13 Akim Demaille <akim@epita.fr>
12864
12865 The computation of nullable is broken: it doesn't handle empty
12866 RHS's properly.
12867
12868 * tests/torture.at (GNU AWK Grammar): New.
12869 * tests/sets.at (Nullable): New.
12870 * src/nullable.c (set_nullable): Instead of blindly looping over
12871 `ritems', loop over the rules, and then over their rhs's.
12872
12873 Work around Autotest bugs.
12874
12875 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
12876 frame, because Autotest understand lines starting with a `+' as
12877 traces from the shell. Then, they are not processed properly.
12878 Admittedly an Autotest bug, but we don't have time to wait for
12879 Autotest to catch up.
12880 * tests/regression.at (Broken Closure): Adjust to the new table
12881 frames.
12882 Move to...
12883 * tests/sets.at: here.
12884
12885 2001-12-13 Akim Demaille <akim@epita.fr>
12886
12887 * src/closure.c (closure): Use nrules instead of playing tricks
12888 with BITS_PER_WORD.
12889
12890 2001-12-13 Akim Demaille <akim@epita.fr>
12891
12892 * src/print.c (print_actions): Output the handling of `$' as the
12893 traces do: shifting the token EOF. Before EOF was treated as a
12894 nonterminal.
12895 * tests/regression.at: Adjust some tests.
12896 * src/print_graph.c (print_core): Complete the set of items via
12897 closure. The next-to-final and final states are still unsatisfying,
12898 but that's to be addressed elsewhere.
12899 No longer output the rule numbers, but do output the state number.
12900 A single loop for the shifts + gotos is enough, but picked a
12901 distinct color for each.
12902 (print_graph): Initialize and finalize closure.
12903
12904 2001-12-13 Akim Demaille <akim@epita.fr>
12905
12906 * src/reader.c (readgram): Remove dead code, an strip useless
12907 braces.
12908 (get_type): Remove, unused.
12909
12910 2001-12-12 Akim Demaille <akim@epita.fr>
12911
12912 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
12913 on that of lib/error.c.
12914
12915 2001-12-12 Akim Demaille <akim@epita.fr>
12916
12917 Some hosts don't like `/' in includes.
12918
12919 * src/system.h: Include libgettext.h without qualifying the path.
12920 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
12921 $(top_srcdir).
12922
12923 2001-12-11 Marc Autret <autret_m@epita.fr>
12924
12925 * src/output.c (output_parser): Remove useless muscle.
12926
12927 2001-12-11 Marc Autret <autret_m@epita.fr>
12928
12929 * src/bison.simple: Remove #line just before %%epilogue. It
12930 is now handled in ...
12931 * src/reader.c (read_additionnal_code): Add the output of a
12932 #line for the epilogue.
12933
12934 2001-12-10 Marc Autret <autret_m@epita.fr>
12935
12936 * src/reader.c (copy_definition): Re-use CPP-outed code which
12937 replace precedent remove.
12938 * src/bison.simple: Remove #line before %%prologue because
12939 %%input-line is wrong at this time.
12940
12941 2001-12-10 Marc Autret <autret_m@epita.fr>
12942
12943 * src/reader.c (symbols_output): Clean up.
12944 * src/output.c (output_gram, output): Clean up.
12945
12946 2001-12-10 Akim Demaille <akim@epita.fr>
12947
12948 * src/lalr.c (initialize_lookaheads): New. Extracted from...
12949 * src/LR0.c (set_state_table): here.
12950 * src/lalr.c (lalr): Call it.
12951
12952 2001-12-10 Akim Demaille <akim@epita.fr>
12953
12954 * src/state.h (shifts): Remove the `number' member: shifts are
12955 attached to state, hence no longer need to be labelled with a
12956 state number.
12957
12958 2001-12-10 Akim Demaille <akim@epita.fr>
12959
12960 Now that states have a complete set of members, the linked list of
12961 shifts is useless: just fill directly the state's shifts member.
12962
12963 * src/state.h (shifts): Remove the `next' member.
12964 * src/LR0.c (first_state, last_state): Remove.
12965 Adjust the callers.
12966 (augment_automaton): Don't look for the shifts that must be added
12967 a shift on EOF: it is those of the state we looked for! But now,
12968 since shifts are attached, it is no longer needed to looking
12969 merely by its id: its number.
12970
12971 2001-12-10 Akim Demaille <akim@epita.fr>
12972
12973 * src/LR0.c (augment_automaton): Better variable locality.
12974 Remove an impossible branch: if there is a state corresponding to
12975 the start symbol being shifted, then there is shift for the start
12976 symbol from the initial state.
12977
12978 2001-12-10 Akim Demaille <akim@epita.fr>
12979
12980 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
12981 only when appropriate: when insert_start_shifting_state' is not
12982 invoked.
12983 * tests/regression.at (Rule Line Numbers): Adjust.
12984
12985 2001-12-10 Akim Demaille <akim@epita.fr>
12986
12987 * src/LR0.c (augment_automaton): Now that all states have shifts,
12988 merge the two cases addition shifts to the initial state.
12989
12990 2001-12-10 Akim Demaille <akim@epita.fr>
12991
12992 * src/lalr.c (set_state_table): Move to...
12993 * src/LR0.c: here.
12994 * src/lalr.c (lalr): Don't call it...
12995 * src/LR0.c (generate_states): do it.
12996 * src/LR0.h (first_state): Remove, only the table is used.
12997
12998 2001-12-10 Akim Demaille <akim@epita.fr>
12999
13000 * src/LR0.h (first_shift, first_reduction): Remove.
13001 * src/lalr.c: Don't use first_shift: find shifts through the
13002 states.
13003
13004 2001-12-10 Akim Demaille <akim@epita.fr>
13005
13006 * src/LR0.c: Attach shifts to states as soon as they are
13007 computed.
13008 * src/lalr.c (set_state_table): Instead of assigning shifts to
13009 state, just assert that the mapping was properly done.
13010
13011 2001-12-10 Akim Demaille <akim@epita.fr>
13012
13013 * src/LR0.c (insert_start_shift): Rename as...
13014 (insert_start_shifting_state): this.
13015 (insert_eof_shifting_state, insert_accepting_state): New.
13016 (augment_automaton): Adjust.
13017 Better locality of the variables.
13018 When looking if the start_symbol is shifted from the initial
13019 state, using `while (... symbol != start_symbol ...)' sounds
13020 better than `while (... symbol < start_symbol ...)': If fail
13021 to see how the order between symbols could be relevant!
13022
13023 2001-12-10 Akim Demaille <akim@epita.fr>
13024
13025 * src/getargs.h: Don't declare `spec_name_prefix' and
13026 `spec_file_prefix', declared by src/files.h.
13027 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
13028 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
13029 * src/output.c (prepare): Adjust.
13030 * src/reader.c (symbols_output): Likewise.
13031 * src/vmsgetargs.c: Vaguely adjust, but who cares?
13032
13033 2001-12-10 Akim Demaille <akim@epita.fr>
13034
13035 * src/muscle_tab.c (muscle_init): NULL is a better default than
13036 `"0"'.
13037
13038 2001-12-10 Akim Demaille <akim@epita.fr>
13039
13040 * src/reader.c (reader): Calling symbols_output once is enough.
13041
13042 2001-12-10 Akim Demaille <akim@epita.fr>
13043
13044 Now that states have a complete set of members, the linked list of
13045 reductions is useless: just fill directly the state's reductions
13046 member.
13047
13048 * src/state.h (struct reductions): Remove member `number' and
13049 `next'.
13050 * src/LR0.c (first_reduction, last_reduction): Remove.
13051 (save_reductions): Don't link the new reductions, store them in
13052 this_state.
13053 * src/lalr.c (set_state_table): No need to attach reductions to
13054 states, it's already done.
13055 * src/output.c (output_actions): No longer free the shifts, then
13056 the reductions, then the states: free all the states and their
13057 members.
13058
13059 2001-12-10 Akim Demaille <akim@epita.fr>
13060
13061 * src/options.c (OPTN, DRTV, BOTH): New.
13062 (option_table): Use them.
13063
13064 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
13065 the job of system.h.
13066 * src/options.c: Don't include stdio.h and xalloc.h for the same
13067 reasons.
13068
13069 2001-12-10 Akim Demaille <akim@epita.fr>
13070
13071 * src/output.c (output, prepare): Make sure the values of the
13072 muscles `action' and `prologue' are 0-terminated.
13073
13074 2001-12-10 Akim Demaille <akim@epita.fr>
13075
13076 Clean up GCC warnings.
13077
13078 * src/reader.c (copy_action): `buf' is not used.
13079 (parse_skel_decl): Be static.
13080 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
13081 * src/options.h (create_long_option_table): Have a real prototype.
13082 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
13083 (hash_delete_at): Return const void *.
13084 Adjust casts to preserve the const.
13085
13086 2001-12-10 Akim Demaille <akim@epita.fr>
13087
13088 * configure.in: Require 2.52g.
13089 M4 is not needed, but AUTOM4TE is.
13090 * m4/m4.m4: Remove.
13091 * tests/Makefile.am: Adjust.
13092
13093 2001-12-10 Akim Demaille <akim@epita.fr>
13094
13095 One structure for states is enough, even though theoretically
13096 there are LR(0) states and LALR(1) states.
13097
13098 * src/lalr.h (state_t): Remove.
13099 (state_table): Be state_t **, not state_t *.
13100 * src/state.h (core, CORE_ALLOC): Rename as...
13101 (state_t, STATE_ALLOC): this.
13102 Add the LALR(1) members: shifts, reductions, errs.
13103 * src/LR0.c (state_table): Rename as...
13104 (state_hash): this, to avoid name clashes with the global
13105 `state_table'.
13106 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
13107 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
13108
13109 2001-12-10 Akim Demaille <akim@epita.fr>
13110
13111 Bison dumps core on bash.y.
13112 Reported by Pascal Bart.
13113
13114 * src/warshall.c (bitmatrix_print): New.
13115 (TC): Use it.
13116 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
13117 j must be the outer loop.
13118 * tests/regression.at (Broken Closure): New.
13119
13120 2001-12-05 Akim Demaille <akim@epita.fr>
13121
13122 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
13123 its argument.
13124 Reported by Peter Hamorsky.
13125
13126 2001-12-05 Akim Demaille <akim@epita.fr>
13127
13128 * src/conflicts.c (err_table): Remove.
13129 (resolve_sr_conflict): Adjust.
13130 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
13131 Rename as...
13132 (state_t.reductions, state_t.shifts): this.
13133
13134 2001-12-05 Akim Demaille <akim@epita.fr>
13135
13136 * src/reduce.c (reduce_grammar_tables): No longer disable the
13137 removal of useless rules via CPP but via `if (0)', so that the
13138 compiler still check the code is valid.
13139 For instance, it should have noticed `rline' no longer exists: use
13140 the `line' member of rule_t.
13141 * src/gram.c (dummy, rline): Remove, unused.
13142
13143 2001-12-05 Akim Demaille <akim@epita.fr>
13144
13145 * src/output.c (pack_vector): Use assert, not berror.
13146 * src/main.c (berror): Remove, unused.
13147
13148 2001-12-05 Akim Demaille <akim@epita.fr>
13149
13150 New experimental feature: if --verbose --trace output all the
13151 items of a state, not only its kernel.
13152
13153 * src/print.c (print_core): If `trace_flag', then invoke closure
13154 before outputting the items of the state (print_core is no longer
13155 a correct name them).
13156 (print_results): Invoke new_closure/free_closure if needed.
13157
13158 2001-12-05 Akim Demaille <akim@epita.fr>
13159
13160 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
13161 * src/closure.c, src/closure.h (itemsetsize): Rename as...
13162 (nitemset): for consistency with the rest of the project.
13163
13164 2001-12-05 Akim Demaille <akim@epita.fr>
13165
13166 * src/closure.c (print_closure): Improve.
13167 (closure): Use it for printing input and output.
13168
13169 2001-12-05 Akim Demaille <akim@epita.fr>
13170
13171 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
13172 indexed by nonterminals.
13173
13174 2001-12-05 Akim Demaille <akim@epita.fr>
13175
13176 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
13177 what it was!).
13178 * src/warshall.h: Remove accidental duplication of the content.
13179
13180 2001-12-05 Akim Demaille <akim@epita.fr>
13181
13182 * src/closure.c (set_fderives): De-obfuscate.
13183
13184 2001-12-05 Akim Demaille <akim@epita.fr>
13185
13186 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
13187
13188 2001-12-05 Akim Demaille <akim@epita.fr>
13189
13190 * src/closure.c (set_firsts): De-obfuscate.
13191
13192 2001-12-05 Akim Demaille <akim@epita.fr>
13193
13194 * src/output.c (action_row): De-obfuscate
13195 using the good o' techniques: arrays not pointers, variable
13196 locality, BITISSET, RESETBIT etc.
13197
13198 2001-12-05 Akim Demaille <akim@epita.fr>
13199
13200 Pessimize the code to simplify it: from now on, all the states
13201 have a valid SHIFTS, which NSHIFTS is possibly 0.
13202
13203 * src/LR0.c (shifts_new): Be global and move to..
13204 * src/state.c, src/state.h: here.
13205 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
13206 * src/print_graph: Adjust.
13207
13208 2001-12-05 Akim Demaille <akim@epita.fr>
13209
13210 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
13211 * src/conflicts.c: Use it.
13212 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
13213 incorrectly ``simplified''.
13214
13215 2001-12-05 Akim Demaille <akim@epita.fr>
13216
13217 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
13218 using the good o' techniques: arrays not pointers, variable
13219 locality, BITISSET, RESETBIT etc.
13220
13221 2001-12-05 Akim Demaille <akim@epita.fr>
13222
13223 * src/state.h (SHIFT_SYMBOL): New.
13224 * src/conflicts.c: Use it to deobfuscate.
13225
13226 2001-12-05 Akim Demaille <akim@epita.fr>
13227
13228 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
13229 (print_reductions): De-obfuscate using the good o' techniques:
13230 arrays not pointers, variable locality, BITISSET.
13231
13232 2001-12-05 Akim Demaille <akim@epita.fr>
13233
13234 * src/conflicts.c (print_reductions): Arrays, not pointers.
13235 Use BITISSET.
13236
13237 2001-12-05 Akim Demaille <akim@epita.fr>
13238
13239 * src/conflicts.c (print_reductions): Pessimize, but clarify.
13240
13241 2001-12-05 Akim Demaille <akim@epita.fr>
13242
13243 * src/conflicts.c (print_reductions): Improve variable locality.
13244
13245 2001-12-05 Akim Demaille <akim@epita.fr>
13246
13247 * src/conflicts.c (print_reductions): Pessimize, but clarify.
13248
13249 2001-12-05 Akim Demaille <akim@epita.fr>
13250
13251 * src/conflicts.c (print_reductions): Improve variable locality.
13252
13253 2001-12-05 Akim Demaille <akim@epita.fr>
13254
13255 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
13256 * src/lalr.c: Use them.
13257
13258 2001-12-05 Akim Demaille <akim@epita.fr>
13259
13260 * src/LR0.c (augment_automaton): Formatting changes.
13261 Better variable locality.
13262
13263 2001-12-05 Akim Demaille <akim@epita.fr>
13264
13265 * src/lalr.c (matrix_print): New.
13266 (transpose): Use it.
13267 Use arrays instead of pointers.
13268
13269 2001-12-05 Akim Demaille <akim@epita.fr>
13270
13271 * src/lalr.c (maxrhs): Move to...
13272 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
13273 * src/lalr.c (build_relations): Adjust.
13274
13275 2001-12-05 Akim Demaille <akim@epita.fr>
13276
13277 * src/lalr.c (transpose): Free the memory allocated to the
13278 argument, as it is replaced by the results by the unique caller.
13279 (build_relations): Merely invoke transpose: it handles the memory
13280 deallocation.
13281 Improve variable locality.
13282 Avoid variables used as mere abbreviations.
13283 (compute_lookaheads): Use arrays instead of pointers.
13284
13285 2001-12-05 Akim Demaille <akim@epita.fr>
13286
13287 * src/lalr.c (initialize_F): Improve variable locality.
13288 Avoid variables used as mere abbreviations.
13289
13290 2001-12-05 Akim Demaille <akim@epita.fr>
13291
13292 * src/derives.c (print_derives): Display the ruleno.
13293 * src/lalr.c (initialize_F, transpose): Better variable locality
13294 to improve readability.
13295 Avoid variables used as mere abbreviations.
13296
13297 2001-12-05 Akim Demaille <akim@epita.fr>
13298
13299 * src/lalr.c (traverse): Use arrays instead of pointers.
13300
13301 2001-12-05 Akim Demaille <akim@epita.fr>
13302
13303 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
13304 the handling of squeue.
13305 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
13306
13307 2001-12-05 Akim Demaille <akim@epita.fr>
13308
13309 Because useless nonterminals are now kept alive (instead of being
13310 `destroyed'), we now sometimes examine them, and store information
13311 related to them. Hence we need to know their number, and adjust
13312 memory allocations.
13313
13314 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
13315 static.
13316 * src/LR0.c (allocate_itemsets): The memory allocated to
13317 `symbol_count' was used for two different purpose: once to count
13318 the number of occurrences of each symbol, and later reassigned to
13319 `shift_symbol', containing the symbol that can be shifted from a
13320 given state.
13321 Deobfuscate, i.e., allocate, use and free `symbol_count' here
13322 only, and...
13323 (new_itemsets): Allocate `shift_symbol' here.
13324 (allocate_itemsets): symbol_count includes useless nonterminals.
13325 Make room for them.
13326 (free_storage): Use `free', not `XFREE', for pointers that cannot
13327 be null.
13328
13329 2001-12-05 Akim Demaille <akim@epita.fr>
13330
13331 * src/nullable.c (set_nullable): Deobfuscate the handling of
13332 ritem.
13333 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
13334
13335 2001-12-05 Akim Demaille <akim@epita.fr>
13336
13337 * src/gram.c, src/gram.h (ritem_print): New.
13338 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
13339 (This useless function was defined only to work around VMS linkers
13340 that can't handle compilation units with variables only).
13341 * src/reduce.c (dump_grammar): Use it to trace the construction of
13342 ritem.
13343
13344 2001-12-04 Paul Eggert <eggert@twinsun.com>
13345
13346 * src/bison.simple (union yyalloc): Change member names
13347 to be the same as the stack names.
13348 (yyparse): yyptr is now union yyalloc *, not char *.
13349 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
13350 and may generate better code on some machines.
13351 (yystpcpy): Use prototype if __STDC__ is defined, not just
13352 if __cplusplus is defined.
13353
13354 2001-11-30 Akim Demaille <akim@epita.fr>
13355
13356 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
13357 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
13358 Gettext doesn't compile cleanly, and dies with -Werror.
13359 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
13360 Include WARNING_CFLAGS here.
13361 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
13362 before being defined.

13427 2001-11-30 Akim Demaille <akim@epita.fr>
13428
13429 Instead of mapping the LHS of unused rules to -1, keep the LHS

13433 * src/print.c (print_grammar): Adjust.

13468 an arbitrary restriction on hosts where size_t is wider than int.
13469
13470 (yyparse): Don't dump core if alloca or malloc fails; instead, report
13471 a parser stack overflow. Allocate just one block of memory for all
13472 three stacks, instead of allocating three blocks; this typically is
13473 faster and reduces fragmentation.
13474
13475 Do not limit the number of items in the stack to a value that fits
13476 in 'int', as this is an arbitrary limit on hosts with 64-bit
13477 size_t and 32-bit int.

13804 2001-11-19 Akim Demaille <akim@epita.fr>
13805
13806 * src/vcg.c: You do the output, so you are responsible of the
13807 handling of VCG syntax, in particular: use quotearg.
13808 * src/print_graph.c: Don't.
13809 (print_actions): Don't output the actions as part of the nodes,
13810 since that's the job of the edges.

13904 * tests/calc.at, tests/output.at, tests/regression.at,
13905 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
13906 now the tests are run in private dirs, therefore AC_CLEANUP and

13908 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
13909 use abs. path to find config.h.
13910 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

13916

13928
13929 * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):

13932 braces to pacify GCC's warnings for `if () if () {} else {}'.
13933 * src/lex.c (parse_percent_token): Replace equal_offset with
13934 arg_offset.
13935 arg is const.

15281
15282 * src/conflicts.c (conflict_report): Be sure not to append to res

15289 New, from fileutils 4.0.37.
15290 * configure.in: Require Autoconf 2.49c. I took some time before
15291 making this decision. This is the only way out for portability
15292 issues in Bison, it would mean way too much duplicate effort to
15293 import in Bison features implemented in 2.49c since 2.13.
15294 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
15295

15307 (init_lex): Initialize it. No longer call...
15308 (grow_token_buffer): this. Remove it.

15310
15311 2001-01-19 Akim Demaille <akim@epita.fr>
15312
15313 * src/lex.h: Rename all the tokens:
15314 s/\bENDFILE\b/tok_eof/g;
15315 s/\bIDENTIFIER\b/tok_identifier/g;
15316 etc.
15317 Let them be enums, not #define, to ease debugging.
15318 Adjust all the code.
15319
15320 2001-01-18 Akim Demaille <akim@epita.fr>
15321

15324
15325 2001-01-18 Akim Demaille <akim@epita.fr>
15326
15327 Since we now use obstacks, more % directives can be enabled.
15328
15329 * src/lex.c (percent_table): Also accept `%yacc',
15330 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

15333 instead of returning a token.
15334 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
15335 * src/reader.c (read_declarations): Adjust.
15336 * src/files.c (open_files): Don't call `compute_base_names', don't
15337 compute `attrsfile' since they depend upon data which might be
15338 *in* the input file now.
15339 (output_files): Do it here.
15340 * src/output.c (output_headers): Document the fact that this patch
15341 introduces a guaranteed SEGV for semantic parsers.
15342 * doc/bison.texinfo: Document them.
15343 * tests/suite.at: Exercise these %options.
15344

15363
15364 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

15366 FILE * parameters.
15367
15368 2000-12-20 Akim Demaille <akim@epita.fr>
15369
15370 * src/files.c (open_files): Actually the `.output' file is based
15371 on the short_base_name, not base_name.
15372 * tests/suite.at (Checking output file names): Adjust.
15373
15374 2000-12-20 Akim Demaille <akim@epita.fr>

15395 Adjust dependencies.
15396
15397 2000-12-19 Akim Demaille <akim@epita.fr>
15398
15399 * src/files.c (strsuffix): New.
15400 (stringappend): Be just like strcat but allocate.
15401 (base_names): Eve out from open_files.
15402 Try to simplify the rather hairy computation of base_name and
15403 short_base_name.
15404 (open_files): Use it.
15405 * tests/suite.at (Checking output file names): New test.
15406

15443 2000-12-19 Akim Demaille <akim@epita.fr>
15444
15445 * src/files.c (open_files): Yipee! We no longer need all the code
15446 looking for `/tmp' since we have no tmp file.
15447
15448 2000-12-19 Akim Demaille <akim@epita.fr>
15449

15479 prevents type checking.
15480 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
15481 cast the value to (void *): assigning a `foo *' to a `void *'

15500
15501 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

15543
15544 2000-11-03 Akim Demaille <akim@epita.fr>
15545
15546 For some reason, this was not applied.
15547
15548 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

15561 (done): Rename as...
15562 (output_files): this.
15563 Use `obstack_save'.
15564 * src/main.c (main): Don't use `atexit' to register `done', since
15565 it no longer has to remove tmp files, just call `output_files'
15566 when there are no errors.

15637
15638 * src/reader.c (copy_comment2): Expect the input stream to be on
15639 the `/' which is suspected to open a comment, instead of being
15640 called after `//' or `/*' was read.
15641 (copy_comment, copy_definition, parse_union_decl, copy_action)
15642 (copy_guard): Adjust.
15643
15644 2000-10-16 Akim Demaille <akim@epita.fr>
15645
15646 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
15647 `read_signed_integer'.
15648
15649 2000-10-16 Akim Demaille <akim@epita.fr>
15650
15651 * src/reader.c (copy_dollar): New function.

15669
15670 2000-10-04 Akim Demaille <akim@epita.fr>
15671
15672 When a literal string is used to define two different tokens,
15673 `bison -v' segfaults.
15674 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
15675

15685 From Neil Booth.
15686
15687 2000-10-02 Paul Eggert <eggert@twinsun.com>
15688
15689 * bison.s1 (yyparse): Assign the default value
15690 unconditionally, to avoid a GCC warning and make the parser a
15691 tad smaller.
15692
15693 2000-10-02 Akim Demaille <akim@epita.fr>
15694
15695 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
15696 options.
15697
15698 2000-10-02 Akim Demaille <akim@epita.fr>
15699
15700 * src/derives.c, src/print.c, src/reduce.c: To ease the
15701 translation, move some `\n' out of the translated strings.
15702
15703 2000-10-02 Akim Demaille <akim@epita.fr>
15704
15705 The location tracking mechanism is precious for parse error
15706 messages. Nevertheless, it is enabled only when `@n' is used in
15707 the grammar, which is a different issue (you can use it in error
15708 message, but not in the grammar per se). Therefore, there should
15709 be another means to enable it.
15710
15711 * src/getargs.c (getargs): Support `--locations'.
15712 (usage): Report it.
15713 * src/getargs.h (locationsflag): Export it.
15714 * src/lex.c (percent_table): Support `%locations'.
15715 * src/reader.c (yylsp_needed): Remove this variable, now replaced
15716 with `locationsflag'.
15717 * doc/bison.texinfo: Document `--locations' and `%locations'.
15718 Sort the options.
15719 * tests/calc.m4: Test it.
15720
15721 For regularity of the names, replace each
15722 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
15723 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
15724 In addition replace each `flag' with `_flag'.
15725
15726 2000-10-02 Akim Demaille <akim@epita.fr>
15727
15728 Also test parse error messages, including with YYERROR_VERBOSE.
15729
15730 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
15731 associative).
15732 Use it to check the computations.
15733 Use it to check `nonassoc' is honored.
15734 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
15735 `--yyerror-verbose'.
15736 (_AT_CHECK_CALC): Adjust to this option.
15737 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
15738
15739 2000-10-02 Akim Demaille <akim@epita.fr>
15740
15741 Test also `--verbose', `--defines' and `--name-prefix'. Testing
15742 the latter demonstrates a flaw in the handling of non debugging
15743 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
15744 was used in order to simplify:
15745
15746 #if YYDEBUG
15747 if (yydebug)
15748 {
15749 ...
15750 }
15751 #endif
15752
15753 into
15754
15755 if (yydebug)
15756 {
15757 ...
15758 }
15759
15760 unfortunately this leads to a CPP conflict when
15761 `--name-prefix=foo' is used since it produces `#define yydebug
15762 foodebug'.
15763
15764 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
15765 (YYDPRINTF): New macro.
15766 Spread its use.
15767 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
15768 the bison options.
15769 Also test `--verbose', `--defines' and `--name-prefix'.
15770
15771 2000-10-02 Akim Demaille <akim@epita.fr>
15772
15773 Improve the readability of the produced parsers.
15774
15775 * src/bison.s1: Formatting changes.
15776 Improve the comment related to the `$' mark.
15777 (yydefault): Don't fall through to `yyresume': `goto' there.
15778 * src/output.c (output_parser): When the `$' is met, skip the end
15779 of its line.
15780 New variable, `number_of_dollar_signs', to check there's exactly
15781 one `$' in the parser skeleton.
15782
15783 2000-10-02 Akim Demaille <akim@epita.fr>
15784
15785 * lib/xstrdup.c: New file, from the fileutils.
15786 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
15787 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
15788 instead of strlen + xmalloc + strcpy.
15789 * src/symtab.c (copys): Remove, use xstrdup instead.
15790
15791 2000-10-02 Akim Demaille <akim@epita.fr>
15792
15793 * src/gram.h (associativity): New enum type which replaces the
15794 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
15795 `right_assoc', `left_assoc' and `non_assoc'.
15796 Adjust all dependencies.
15797 * src/reader.c: Formatting changes.
15798 (LTYPESTR): Don't define it, use it as a literal in
15799 `reader_output_yylsp'.
15800 * src/symtab.h (symbol_class): New enum type which replaces the
15801 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
15802 `sunknown', `stoken and `snterm'.
15803
15804 2000-10-02 Akim Demaille <akim@epita.fr>
15805
15806 * src/getargs.c (fixed_outfiles): Rename as...
15807 (yaccflag): for consistency and accuracy.
15808 Adjust dependencies.
15809
15810 2000-10-02 Akim Demaille <akim@epita.fr>
15811
15812 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15813 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15814 difficult and introduced a lot of core dump. It turns out that
15815 Bison used an implementation of `xmalloc' based on `calloc', and
15816 at various places it does depend upon the initialization to 0. I
15817 have not tried to isolate the pertinent places, and all the former
15818 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
15819 someone should address this issue.
15820
15821 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
15822 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
15823 files.
15824 Adjust dependencies.
15825 * src/warshall.h: New file.
15826 Propagate.

15833
15834 2000-10-02 Akim Demaille <akim@epita.fr>
15835
15836 * src/state.h (nstates, final_state, first_state, first_shift)
15837 (first_reduction): Move their exportation from here...
15838 * src/LR0.h: to here.
15839 Adjust dependencies.
15840 * src/getargs.c (statisticsflag): New variable.
15841 Add support for `--statistics'.
15842 Adjust dependencies.

15863 (conflict_log, verbose_conflict_log): Replace with...
15864 (print_conflicts): this function.
15865 Adjust dependencies.
15866 * src/conflicts.h: New file.
15867 Propagate its inclusion.
15868
15869 2000-10-02 Akim Demaille <akim@epita.fr>

15894 * src/reader.h: New file.
15895 Propagate its use instead of tedious list of `extern' and
15896 prototypes.
15897 * src/reader.c: Formatting changes, topological sort,
15898 s/register//.
15899
15900 2000-10-02 Akim Demaille <akim@epita.fr>
15901
15902 * src/lex.h: Prototype `lex.c' exported functions.

15913
15914 2000-10-02 Akim Demaille <akim@epita.fr>
15915
15916 * src/output.c (token_actions): Introduce a temporary array,
15917 YYDEFACT, that makes it possible for this function to use
15918 output_short_table.
15919
15920 2000-10-02 Akim Demaille <akim@epita.fr>
15921
15922 `user_toknums' is output as a `short[]' in `output.c', while it is
15923 defined as a `int[]' in `reader.c'. For consistency with the
15924 other output tables, `user_toknums' is now defined as a table of
15925 shorts.
15926
15927 * src/reader.c (user_toknums): Be a short table instead of an int
15928 table.
15929 Adjust dependencies.
15930
15931 Factor the short table outputs.
15932
15933 * src/output.c (output_short_table): New function.

15944 from output.c.

15946 2000-09-21 Akim Demaille <akim@epita.fr>
15947

15961 * src/Makefile.am (noinst_HEADERS): Adjust.
15962
15963 2000-09-20 Akim Demaille <akim@epita.fr>
15964
15965 * src/acconfig.h: Don't protect config.h against multiple
15966 inclusion.
15967 Don't define PARAMS.
15968 * src/system.h: Define PARAMS.
15969 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
15970 purpose of config.h. system.h must not try to fix wrong
15971 definitions in config.h.
15972
15973 2000-09-20 Akim Demaille <akim@epita.fr>
15974
15975 * src/derives.h: New file.

16189 Change the handling of @s so that they behave exactly like $s.
16190 There is now a pseudo variable @$ (readble and writable), location
16191 of the lhs of the rule (by default ranging from the location of
16192 the first symbol of the rhs, to the location of the last symbol,

16228 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

16899 (print_notices): Remove final `.' from error message.
16900
16901 * src/reader.c (reader_output_yylsp):
16902 New function.
16903 (readgram): Use `#if 0' around code that accepted %command
16904 inside grammar rules: The documentation doesn't allow it,
16905 and it will fail since the %command processors scan for the next %.
16906 (parse_token_decl): Extended the %token
16907 declaration to allow a multi-character symbol as an alias.
16908 (parse_thong_decl): New function.
16909 (read_declarations): Added %thong declarations.
16910 (read_declarations): Handle NOOP to deal with allowing
16911 % declarations as another means to specify the flags.
16912 (readgram): Allow %prec prior to semantics embedded in a rule.
16913 (skip_to_char, read_declarations, copy_definition)
16914 (parse_token_decl, parse_start_decl, parse_type_decl)
16915 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
16916 (get_type_name, copy_guard, copy_action, readgram)
16917 (get_type, packsymbols): Revised most error messages.
16918 Changed `fatal' to `warnxxx' to avoid aborting for error.
16919 Revised and use multiple warnxxx functions to avoid using VARARGS1.
16920 (read_declarations): Improve the error message for
16921 an invalid character. Do not abort.
16922 (read_declarations, copy_guard, copy_action): Use
16923 printable_version to avoid unprintable characters in printed output.
16924 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
16925 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
16926 Allow the type of a non-terminal can be given
16927 more than once, as long as all specifications give the same type.
16928
16929 * src/output.c:
16930 (output_headers, output_trailers, output, output_gram)
16931 (output_rule_data): Implement noparserflag variable.
16932 Implement toknumflag variable.
16933 (output): Call reader_output_yylsp to output LTYPESTR.
16934
16935 * src/main.c (main):
16936 If reader sees an error, don't process the grammar.
16937 (fatals): Updated to not use VARARGS1.
16938 (printable_version, int_to_string, warn, warni, warns, warnss)
16939 (warnsss): New error reporting functions. Avoid abort for error.
16940
16941 * src/lex.h:
16942 Added THONG and NOOP for alias processing.
16943 Added SETOPT for the new code that allows setting options with %flags.
16944
16945 * src/lex.c:
16946 Include getopt.h. Add some extern decls.
16947 (safegetc): New function to deal with EOF gracefully.
16948 (literalchar); new function to deal with reading \ escapes.
16949 (lex): Use literalchar.
16950 (lex): Implemented "..." tokens.
16951 (literalchar, lex, parse_percent_token): Made tokenbuffer
16952 always contain the token. This includes growing the token
16953 buffer while reading an integer.
16954 (parse_percent_token): Replaced if-else statement with percent_table.
16955 (parse_percent_token): Added % declarations as another
16956 way to specify the flags -n, -l, and -r. Also added hooks for
16957 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
16958 major changes to files.c.
16959 (lex) Retain in the incoming stream a character following
16960 an incorrect '/'.
16961 (skip_white_space, lex): Revised most error messages
16962 and changed fatal to warn to avoid aborting.
16963 (percent_table): Added %thong declarations.
16964
16965 * src/gram.h: Comment changes.
16966
16967 * src/files.c (openfiles, open_extra_files, done):
16968 Add faction flag
16969 and actfile file. Handle noparserflag. Both for -n switch.
16970
16971 * src/conflicts.c (resolve_sr_conflict):
16972 Remove use of alloca.
