[bison.git] / ChangeLog
1 2003-08-26 Akim Demaille <akim@epita.fr>
2
3 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
4 "<\#" to avoid magic from Gnus when posting parts of this script.
5
6 2003-08-26 Akim Demaille <akim@epita.fr>
7
8 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
9 (Parser::parse): here.
10 Adjust: nerrs and errstatus is now replaced by...
11 (Parser::nerrs_, Parser::errstatus_): New.
12
13 2003-08-25 Akim Demaille <akim@epita.fr>
14
15 * config/announce-gen, Makefile.cfg: New.
16 * Makefile.am: Adjust.
17 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
18 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
19
20 2003-08-25 Akim Demaille <akim@epita.fr>
21
22 When reducing initial empty rules, Bison parser read an initial
23 location that is not defined. This results in garbage, and that
24 affects Bison's own parser. Therefore we need (i) to extend Bison
25 to support a means to initialize this location, and (ii) to use
26 this CVS Bison to fix CVS Bison's parser.
27
28 * src/reader.h, reader.c (epilogue_augment): Remove, replace
29 with...
30 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
31 * src/parse-gram.y: Adjust.
32 (%initial-action): New.
33 (%error-verbose): Since we require CVS Bison, there is no reason
34 not to use it.
35 * src/scan-gram.l: Adjust.
36 * src/Makefile.am (YACC): New, to make sure we use our own parser.
37 * data/yacc.c (yyparse): Use b4_initial_action.
38
39 2003-08-25 Akim Demaille <akim@epita.fr>
40
41 * doc/bison.texinfo: Don't promote stdout for error messages.
42
43 2003-08-25 Akim Demaille <akim@epita.fr>
44
45 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
46 From Alexandre Duret-Lutz.
47
48 2003-08-25 Akim Demaille <akim@epita.fr>
49
50 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
51 Use them.
52
53 2003-08-25 Akim Demaille <akim@epita.fr>
54
55 * data/lalr1.cc (Parser::reduce_print_): New.
56 Use it.
57
58 2003-08-25 Akim Demaille <akim@epita.fr>
59
60 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
61 error recovery loops. This patch is based on
62 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
63 Also, augment the similarity between lalr1.cc and yacc.c.
64 Note: the locations of error recovery rules are not correct yet.
65
66 * data/lalr1.cc: Comment changes to augment the similarity between
67 lalr1.cc and yacc.c.
68 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
69 (yyerrlab1): Remove, but where it used to be (now the bottom part of
70 yyerrlab), when hitting EOF, pop the whole stack here instead of
71 merely falling thru the default error handling mechanism.
72 (yyerrorlab): New label, with the old contents of YYERROR,
73 plus the following change: pop the stack of rhs corresponding
74 to the production that invoked YYERROR. That is how Yacc
75 behaves (required by POSIX).
76 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
77 fail.
78
79 2003-08-25 Akim Demaille <akim@epita.fr>
80
81 Tune local.at so that people can "autom4te -l autotest calc.at -o
82 calc" for instance, to extract a sub test suite.
83
84 * tests/testsuite.at: Move the initialization, Autotest version
85 requirement, and AT_TESTED invocation into...
86 * tests/local.at: here.
87 * tests/testsuite.at: Include it for compatibility with Autoconf
88 2.57.
89 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
90 be ignore.
91
92 2003-08-04 Paul Eggert <eggert@twinsun.com>
93
94 Rework code slightly to avoid gcc -Wtraditional warnings.
95 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
96 The returned value is now stored in *YY0. All callers changed.
97 * src/output.c (merge_output): Adjust to the above change.
98
99 2003-07-26 Paul Eggert <eggert@twinsun.com>
100
101 * data/glr.c (YYASSERT): New macro.
102 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
103 yyresolveStates, yyprocessOneStack):
104 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
105 Derived from a suggestion by Frank Heckenbach.
106
107 2003-07-25 Paul Eggert <eggert@twinsun.com>
108
109 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
110 for portability to K&R C (after ansi2knr, presumably). See
111 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
112 by Frank Heckenbach, though I have omitted the structure-initialization
113 part of his glr-knr.diff patch since I recall that the Portable
114 C Compiler didn't require that change.
115
116 Let the user specify how to allocate and free memory.
117 Derived from a suggestion by Frank Heckenbach in
118 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
119 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
120 All uses of free, malloc, realloc changed to use these macros,
121 and unnecessary casts removed.
122 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
123
124 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
125
126 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
127 use s.empty() rather than s == "" to test for empty string; see
128 <http://mail.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
129 (trivial change)
130
131 2003-06-25 Akim Demaille <akim@epita.fr>
132
133 * config/depcomp, config/install-sh: Update from masters.
134
135 2003-06-20 Paul Eggert <eggert@twinsun.com>
136
137 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
138 and return properly parenthesized result.
139 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
140 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
141 Remove unnecessary parentheses from uses.
142 * doc/bison.texinfo (Location Default Action): Describe the
143 conventions for parentheses.
144
145 2003-06-19 Paul Eggert <eggert@twinsun.com>
146
147 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
148 yyreportTree): Do not assume that size_t is the same width as int,
149 when printing sizes. Print sizes using an unsigned format.
150 Problem reported by Frank Heckenbach in
151 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
152
153 Port to Forte Developer 7 C compiler.
154 * data/glr.c (struct YYLTYPE): If locations are not being used,
155 declare a single dummy member, as empty structs do not conform
156 to the C standard.
157 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
158 the Forte Developer 7 C compiler complains that end-of-loop
159 code is not reached.
160
161 2003-06-17 Paul Eggert <eggert@twinsun.com>
162
163 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
164 avoid warnings from picky compilers about redefinition of PARAMS.
165
166 2003-06-17 Paul Eggert <eggert@twinsun.com>
167
168 Version 1.875b.
169
170 * NEWS: Document 1.875b.
171
172 * lib/bbitset.h: Do not include config.h; that's the includer's job.
173 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
174 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
175 Don't use 'index' in comments, as it's a builtin fn on some hosts.
176 * lib/bitset_stats.c: Include gettext.h unconditionally, as
177 per recent gettext manual's suggestion.
178 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
179 Use prototypes, not old-style definitions.
180 * lib/lbitset.c (lbitset_unused_clear): Likewise.
181 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
182 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
183 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
184 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
185 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
186 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
187 vbitset_or_and_cmp, vbitset_copy): Likewise.
188
189 * lib/libiberty.h: Do not include config.h; that's the includer's job.
190 Do not include <stdlib.h>.
191 (PARAMS): Define unconditionally for C89.
192 (ATTRIBUTE_NORETURN): Remove.
193 (ATTRIBUTE_UNUSED): Define unconditionally.
194
195 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
196 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
197 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
198 * lib/vbitset.c, lib/vbitset.h: New files.
199 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
200 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
201 from libbitset.
202
203 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
204 `How Can I Reset @code{yyparse}', since texinfo does not allow
205 arbitrary @ in node names.
206
207 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
208 shouldn't be needed according to the gettext 0.12.1 documentation
209 but which seem to be needed anyway: codeset.m4 glibc21.m4
210 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
211 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
212 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
213
214 * lib/.cvsignore: Add stdbool.h.
215 * m4/.cvsignore: Add nls.m4, po.m4.
216
217 Upgrade to CVS gnulib.
218 * stdbool_.h: File renamed from stdbool.h.in.
219 * configure.ac (AM_STDBOOL_H): Invoke this instead of
220 AC_HEADER_STDBOOL.
221 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
222 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
223 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
224 (MOSTLYCLEANFILES): New var.
225 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
226 (stdbool.h): New rule.
227 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
228 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
229 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
230 m4/quote.m4: Upgrade to today's gnulib.
231
232 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
233 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
234 the tests right now.
235 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
236 yyerror are declared before use; C99 requires this.
237
238 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
239
240 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
241 first.
242 (yyrecoverSyntaxError): Correct the logic for setting and testing
243 yyerrState.
244 Correct comment on handling EOF.
245 Allow states with only a default reduction, rather than failing
246 (I can't quite reconstruct why these were not allowed before).
247
248 Fixes to avoid problem that $-N rules in GLR parsers can cause
249 buffer overruns, corrupting state.
250
251 * src/output.c (prepare_rules): Output max_left_semantic_context
252 definition.
253 * src/reader.h (max_left_semantic_context): New variable declaration.
254 * src/scan-gram.l (max_left_semantic_context): Define.
255 (handle_action_dollar): Update max_left_semantic_context.
256 * data/glr.c (YYMAXLEFT): New definition.
257 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
258 (yyresolveAction): Ditto.
259
260 Fixes to problems with location handling in GLR parsers reported by
261 Frank Heckenbach (2003/06/05).
262
263 * data/glr.c (YYLTYPE): Make trivial if locations not used.
264 (YYRHSLOC): Add parentheses, and define only if locations used.
265 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
266 locations not used.
267 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
268 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
269
270 * tests/cxx-type.at: Exercise location information; update tests
271 to differentiate output with and without locations.
272 Remove forward declarations of yylex and yyerror---caused errors
273 because default YYLTYPE not yet defined.
274 Change semantic actions to compute strings, rather than printing
275 them directly (to test proper passing of semantics values). Change
276 output to prefix notation and update test data and expected results.
277 (yylex): Track locations.
278 (stmtMerge): Return value rather than printing, and include arguments
279 in value.
280
281 2003-06-03 Paul Eggert <eggert@twinsun.com>
282
283 Avoid warnings generated by GCC 2.95.4 when Bison is
284 configured with --enable-gcc-warnings.
285 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
286 yy::]b4_parser_class_name[::translate_,
287 yy::Stack::operator[] (unsigned),
288 yy::Stack::operator[] (unsigned) const,
289 yy::Slice::operator[] (unsigned),
290 yy::Slice::operator[] (unsigned) const):
291 Rename local vars to avoid warnings.
292 * tests/glr-regression.at (Improper handling of embedded actions
293 and $-N in GLR parsers): Remove unused local variable from yylex.
294 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
295 (void) as arg when not pure, since we now assume C89 when building
296 Bison. Pacify GCC by using parameter.
297
298 2003-06-02 Paul Eggert <eggert@twinsun.com>
299
300 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
301 yy::Location::lines, yy::Location::columns): Rename arguments
302 to avoid shadowing; this removes a warning generated by GCC 3.3.
303
304 2003-06-01 Paul Eggert <eggert@twinsun.com>
305
306 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
307 to g++, as GCC 3.3 complains if you do it.
308 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
309 everything that WARNING_CFLAGS has, except omit warnings
310 not suitable for C++.
311 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
312 * tests/atlocal.in (CXXFLAGS): New var.
313 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
314
315 Fix a GLR parser bug I reported in February; see
316 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
317 The problem was that GLR parsers did not conform to the C standard,
318 because actions like { $1 = $2 + $3; } expanded to expressions
319 that invoked YYFILL in separate subexpressions, and YYFILL assigned
320 to a local variable. The C standard says that expressions
321 like (var = f ()) + (var = f ()) have undefined behavior.
322 Another problem was that GCC sometimes issues warnings that
323 yyfill and its parameters are unused.
324
325 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
326 as possibly unused.
327 (yyfill): New function.
328 (YYFILL): Use it.
329 (yyuserAction): Change type of yynormal to bool, so that it matches
330 the new yyfill signature. Mark it as possibly unused.
331
332
333 Follow up on a bug I reported in February, where a Bison-generated
334 parser can loop. Provide a test case and a fix for yacc.c. I
335 don't have a fix for lalr1.cc or for glr.c, unfortunately.
336 The original bug report is in:
337 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
338
339 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
340 macro's size was becoming unwieldy.
341 (yyerrlab): Do not discard an empty lookahead symbol, as this
342 might destroy garbage.
343 (yyerrorlab): New label, with the old contents of YYERROR,
344 plus the following change: pop the stack of rhs corresponding
345 to the production that invoked YYERROR. That is how Yacc
346 behaves, and POSIX requires this behavior.
347 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
348 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
349 Define 'alarm' to do nothing if unistd.h is not available.
350 Add a new rule "exp: '-' error;" to test the above change to
351 data/yacc.c. Use 'alarm' to abort any test taking longer than
352 10 seconds, as it's probably looping.
353 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
354 Also, the new yacc.c generates two fewer diagnostics for an
355 existing test.
356
357 2003-05-24 Paul Eggert <eggert@twinsun.com>
358
359 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
360 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
361 This fixes a problem reported by John Bowman when the Compaq/HP
362 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
363 -ansi -Wall -gall).
364 * data/yacc.c (union yyalloc): Likewise.
365 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
366
367 Switch from 'int' to 'bool' where that makes sense.
368
369 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
370 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
371 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
372 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
373 Return or accept bool, not int. All callers changed.
374 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
375 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
376 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
377 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
378 bitset_or_and_cmp_): Likewise.
379 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
380 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
381 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
382 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
383 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
384 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
385 bitset_stats_or_and_cmp): Likewise.
386 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
387 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
388 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
389 ebitset_xor_cmp): Likewise.
390 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
391 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
392 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
393 lbitset_xor_cmp): Likewise.
394 * lib/bbitset.h: Include <stdbool.h>.
395 (struct bitset_vtable): The following members now return bool, not
396 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
397 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
398 or_and_cmp).
399 * src/conflicts.c (count_rr_conflicts): Likewise.
400 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
401 All uses changed.
402 * lib/ebitset.c (ebitset_obstack_init): Likewise.
403 * lib/lbitset.c (lbitset_obstack_init): Likewise.
404 * src/getargs.c (debug_flag, defines_flag, locations_flag,
405 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
406 graph_flag): Likewise.
407 * src/getargs.h (debug_flag, defines_flag, locations_flag,
408 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
409 graph_flag): Likewise.
410 * src/output.c (error_verbose): Likewise.
411 * src/output.h (error_verbose): Likewise.
412 * src/reader.c (start_flag, typed): Likewise.
413 * src/reader.h (typed): Likewise.
414 * src/getargs.c (LOCATIONS_OPTION): New constant.
415 (long_options, getargs): Use it.
416 * src/lalr.c (build_relations): Use bool, not int.
417 * src/nullable.c (nullable_compute): Likewise.
418 * src/print.c (print_reductions): Likewise.
419 * src/tables.c (action_row, pack_vector): Likewise.
420 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
421 * src/output.c (prepare): Use it.
422 * src/output.c (token_definitions_output,
423 symbol_destructors_output, symbol_destructors_output): Use string,
424 not boolean integer, to keep track of whether to output separator.
425 * src/print_graph.c (print_core): Likewise.
426 * src/state.c (state_rule_lookaheads_print): Likewise.
427
428 * config/install-sh: Sync from automake 1.7.5.
429
430 2003-05-14 Paul Eggert <eggert@twinsun.com>
431
432 * src/parse-gram.y (rules_or_grammar_declaration): Require a
433 semicolon after a grammar declaration, in the interest of possible
434 future changes to the Bison input language.
435 Do not allow a stray semicolon at the start of the grammar.
436 (rhses.1): Allow one or more semicolons after any rule, including
437 just before "|" as required by POSIX.
438 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
439 grammar.
440
441 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
442
443 %parse-param support for lalr1.cc.
444
445 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
446 b4_cc_constructor_calls, b4_cc_constructor_call,
447 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
448 definitions.
449 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
450 parse-param arguments.
451 (yy::b4_parser_class_name): Declare instance variables to
452 hold parse-param arguments.
453 * tests/calc.at: s/value/semantic_value/ because value clashes
454 with a member of yy::b4_parser_class_name. Adjust C++ code
455 to handle %parse-param. Enable %parse-param test in C++.
456
457 2003-05-12 Paul Eggert <eggert@twinsun.com>
458
459 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
460 English a bit. Fix fclose typo. Change "const char" to "char
461 const", and use ANSI C rather than K&R for "main". Suggest
462 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
463 and suggest yy_switch_to_buffer.
464
465 2003-05-05 Paul Eggert <eggert@twinsun.com>
466
467 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
468 C89. This avoids a diagnostic on compilers that define __STDC__
469 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
470 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
471
472 2003-05-03 Paul Eggert <eggert@twinsun.com>
473
474 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
475 Do not overrun array bounds.
476 This should fix a bug reported today by Olatunji Oluwabukunmi in
477 <http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
478
479 2003-04-29 Akim Demaille <akim@epita.fr>
480
481 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
482 * src/getargs.c, src/getargs.h: here, as bool, not int.
483 (nondeterministic_parser): New.
484 * src/parse-gram.y, src/scan-gram.l: Support
485 %nondeterministic-parser.
486 * src/output.c (prepare): Use nondeterministic_parser instead
487 of glr_parser where appropriate.
488 * src/tables.c (conflict_row, action_row, save_row)
489 (token_actions, token_actions, pack_vector): Ditto.
490
491 2003-04-29 Akim Demaille <akim@epita.fr>
492
493 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
494
495 2003-04-29 Akim Demaille <akim@epita.fr>
496
497 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
498 with %pure-parser and %locations to exercise the patch from Yakov
499 Markovitch below.
500
501 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
502
503 * data/yacc.c: (b4_lex_param): Corrected for the case where
504 %lex-param is provided and %pure-parser isn't.
505
506 2003-04-27 Paul Eggert <eggert@twinsun.com>
507
508 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
509 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
510 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
511 if it is not defined.
512 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
513
514 2003-04-26 Paul Eggert <eggert@twinsun.com>
515
516 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
517 Declare to be of type suitable for the ninf value itself, not of
518 type suitable for the corresponding table, since the latter might
519 be unsigned but the ninf value might be negative. This fixes a
520 bug reported by Alexandre Duret-Lutz in
521 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
522
523 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
524 invokes it. We shouldn't invoke it twice because it will attempt
525 to put error.o in the archive twice. This fixes a glitch reported
526 by Martin Mokrejs in
527 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
528
529 2003-04-21 Paul Eggert <eggert@twinsun.com>
530
531 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
532 to gnulib.
533
534 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
535
536 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
537 Fix obvious typo that results in uncompilable GLR parsers
538 when both %pure-parser and %locations are used. (trivial change)
539
540 2003-04-17 Paul Eggert <eggert@twinsun.com>
541
542 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
543 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
544 Do not insert the expected token via unput, as this runs afoul
545 of a POSIX-compatibility bug in flex 2.5.31.
546 All uses changed to BEGIN the parent state,
547 since we no longer insert the expected token via unput.
548 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
549 that is no longer emitted after the above change.
550
551 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
552 the first one. This change is from Paul Hilfinger, and it fixes
553 regression reported by Werner Lemberg in
554 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
555
556 (resolve_sr_conflict): Don't invoke state_errs_set
557 unless one or more tokens have been explicitly made errors.
558 Otherwise, the above change causes Bison to abort.
559
560 * tests/existing.at (GNU pic Grammar): New test case, taken from
561 Lemberg's email.
562
563 2003-03-31 Akim Demaille <akim@epita.fr>
564
565 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
566
567 2003-03-31 Akim Demaille <akim@epita.fr>
568
569 * src/output.c (prepare_symbols): Avoid trailing spaces in the
570 output.
571
572 2003-03-31 Akim Demaille <akim@epita.fr>
573
574 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
575 From Paul Hilfinger.
576
577 2003-03-29 Akim Demaille <akim@epita.fr>
578
579 * m4/error.m4: Do not put under dynamic conditions some code which
580 expansion is under static control.
581
582 2003-03-29 Akim Demaille <akim@epita.fr>
583
584 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
585
586 2003-03-29 Akim Demaille <akim@epita.fr>
587
588 * doc/bison.texinfo (Strings are Destroyed): New.
589
590 2003-03-13 Paul Eggert <eggert@twinsun.com>
591
592 * .cvsignore: Add configure.lineno.
593 * src/.cvsignore: Add yacc.
594 * tests/.cvsignore: Add testsuite.log.
595 * doc/fdl.texi: Sync with latest FSF version.
596
597 2003-03-12 Paul Eggert <eggert@twinsun.com>
598
599 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
600 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
601 cursor, instead of leaving it undefined. This fixes a bug
602 reported by Tim Van Holder in
603 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
604 * tests/input.at (Torturing the Scanner): Test the scanner on
605 an empty input file, which was Tim Van Holder's test case.
606
607 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
608 <sys/resource.h> can be included, include sys/time.h and
609 sys/times.h first, if available. This works around the SunOS
610 4.1.4 porting bug reported by Bruce Becker in
611 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
612
613 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
614 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
615 AC_HEADER_SYS_WAIT.
616
617 Merge changes from gnulib. This was prompted because the CVS
618 snapshot didn't build on Solaris 7 due to strnlen problems.
619
620 These changes need to be merged back into gnulib:
621 * lib/hash.c: Include <stdbool.h> unconditionally.
622 * m4/onceonly.m4 (m4_quote): New macro.
623 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
624 Quote AC_FOREACH variable-expansions properly.
625 The 2003-01-03 obstack.h change also needs merging.
626 {end of changes requiring merging}
627
628 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
629 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
630 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
631 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
632 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
633 New files, imported from gnulib.
634 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
635 above.
636
637 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
638 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
639 gnulib sources.
640
641 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
642 Add.
643 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
644 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
645 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
646 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
647 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
648 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
649 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
650 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
651 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
652 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
653 (jm_PREREQ_ARGMATCH): Remove.
654 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
655 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
656
657 * src/system.h: Include <stdbool.h> unconditionally.
658
659 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
660 assuming at least C89 in the bitset code for some time now.
661
662 2003-03-03 Akim Demaille <akim@epita.fr>
663
664 * ro.po: New.
665
666 2003-03-02 Akim Demaille <akim@epita.fr>
667
668 * doc/bison.texinfo (Table of Symbols): Reactivate the
669 documentation for %lex-param, and %parse-param.
670
671 2003-03-02 Akim Demaille <akim@epita.fr>
672
673 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
674 generate verbose error messages.
675 Use the number of tokens as an upper bound in yytname, as it
676 cannot be a non terminal.
677
678 2003-03-02 Akim Demaille <akim@epita.fr>
679
680 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
681 message.
682
683 2003-03-02 Akim Demaille <akim@epita.fr>
684
685 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
686 Use them to exercise yycheck overrun.
687 Based on Andrew Suffield's grammar.
688
689 2003-03-02 Akim Demaille <akim@epita.fr>
690
691 Create tests/local.at for Bison generic testing macros.
692
693 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
694 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
695 This new file.
696 * tests/calc.at (AT_CHECK_CALC): Adjust.
697 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
698 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
699 * tests/local.at: here.
700 (AT_COMPILE_CXX): Tags the tests using it as c++.
701 Ignore the test if CXX is not functional.
702
703 2003-03-01 Paul Eggert <eggert@twinsun.com>
704
705 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
706 not loc->end, since loc->end might contain garbage and this leads
707 to undefined behavior on some platforms.
708 (id_loc, token_start): Use (IF_LINTed) initial values that do not
709 depend on *loc, so that the reader doesn't give the the false
710 impression that *loc is initialized.
711 (<INITIAL>"%%"): Do not bother setting code_start, since its value
712 does not survive the return.
713
714 2003-03-01 Akim Demaille <akim@epita.fr>
715
716 * src/scan-gram.l (code_start): Always initialize it when entering
717 into yylex, as SC_EPILOGUE is activated *before* the corresponding
718 yylex invocation. An alternative would be making it static, but
719 then it starts with the second %%'s beginning, instead of its end.
720
721 2003-02-28 Paul Eggert <eggert@twinsun.com>
722
723 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
724 around a UnixWare 7.1.1 porting bug reported by John Hughes in
725 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
726
727 2003-02-26 Paul Eggert <eggert@twinsun.com>
728
729 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
730 Remove Sequent/Pyramid discussion (nobody uses them any more).
731 Merge VMS and MS-DOS discussion; these ports may well be dead
732 but let's keep mentioning them for now. Put <> around email
733 addresses. Add copyright notice.
734
735 2003-02-24 Paul Eggert <eggert@twinsun.com>
736
737 * data/glr.c (yy_reduce_print): yylineno -> yylno,
738 to avoid collision with flex use of yylineno.
739 Problem reported by Bruce Lilly in
740 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
741 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
742 * data/yacc.c (yy_reduce_print): Likewise.
743
744 * config/depcomp: Sync with Automake 1.7.3.
745
746 2003-02-21 Akim Demaille <akim@epita.fr>
747
748 * data/lalr1.cc: Use temporary variables instead of casts to
749 change integer types.
750 Suggested by Paul Eggert.
751
752 2003-02-21 Akim Demaille <akim@epita.fr>
753
754 * doc/bison.texinfo: Use "location" consistently to refer to @n,
755 to avoid confusions with lalr1.cc's notion of Position.
756 Suggested by Paul Eggert.
757
758 2003-02-20 Akim Demaille <akim@epita.fr>
759
760 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
761 before initial_columns.
762 (location.hh): Use consistent variable names when defining the
763 operator<<.
764 Use "last" so that we subtract from Positions, not from unsigned.
765
766 2003-02-20 Akim Demaille <akim@epita.fr>
767
768 * data/lalr1.cc (position.hh): New subfile, including the extended
769 and Doxygen'ed documentation of class Position.
770 (location.hh): Use it.
771 Document a` la Doxygen.
772 With the help of Benoit Perrot.
773
774 2003-02-20 Akim Demaille <akim@epita.fr>
775
776 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
777 AT_YACC_IF.
778 Redefine AT_YYERROR_SEES_LOC_IF using it.
779 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
780 not defined.
781 Don't use the location in yy::Parser::error_ and
782 yy::Parser::print_ when not %locations.
783 Activate more lalr1.cc tests.
784
785 2003-02-19 Akim Demaille <akim@epita.fr>
786
787 * data/lalr1.cc: When displaying a line number, be sure to make it
788 an int.
789
790 2003-02-19 Akim Demaille <akim@epita.fr>
791
792 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
793 Remove, useless.
794 (YYABORT, YYACCEPT, YYERROR): New.
795 * tests/calc.at: Renable the lalr1.cc test.
796
797 2003-02-19 Akim Demaille <akim@epita.fr>
798
799 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
800 error recovery, mixing with/without pops and discarding of the
801 lookahead.
802 Exercise YYERROR.
803 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
804
805 2003-02-17 Paul Eggert <eggert@twinsun.com>
806
807 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
808 * tests/testsuite.at (AT_COMPILE): Use them.
809 This fixes the testsuite problem reported by Robert Lentz in
810 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
811
812 2003-02-12 Paul Eggert <eggert@twinsun.com>
813
814 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
815 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
816 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
817 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
818 Check for malloc failure, for consistency with yacc.c.
819 (yytname_size): Remove, for consistency with yacc.c.
820
821 The bug still remains in data/lalr1.cc, as I didn't have time
822 to fix it there.
823
824 2003-02-06 Akim Demaille <akim@epita.fr>
825
826 * configure.ac (GXX): Rename as...
827 (CXX): this, to keep the original Autoconf semantics.
828 Require 2.57.
829 * data/lalr1.cc: Fix b4_copyright invocations.
830 If YYDEBUG is not defined, don't depend upon name_ being defined.
831 (location.hh): Include string and iostream.
832 (Position::filename): New member.
833 (Position::Position ()): New.
834 (operator<< (Position)): New.
835 (operator- (Position, int)): New.
836 (Location::first, Location::last): Rename as...
837 (Location::begin, Location::end): these, to mock the conventional
838 iterator names.
839 (operator<< (Location)): New.
840 * tests/atlocal.in (CXX): New.
841 * tests/testsuite.at (AT_COMPILE_CXX): New.
842 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
843 locations in a more synthetic way.
844 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
845 lalr1.cc is used.
846 Adjust the C locations to match those from Emacs: first column is
847 column 0.
848 Change all the expected results.
849 Conform to the GCS: simplify the locations when applicable.
850 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
851 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
852 these CPP macros with the m4 macros new defined by...
853 (AT_CHECK_PUSHDEFS): this, i.e.:
854 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
855 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
856 New macros.
857 (AT_CHECK_POPDEFS): Undefine them.
858 (AT_CHECK_CALC_LALR1_CC): New.
859 Use it for the first lalr1.cc test.
860
861 2003-02-04 Akim Demaille <akim@epita.fr>
862
863 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
864 Location as is defined.
865
866 2003-02-04 Akim Demaille <akim@epita.fr>
867
868 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
869 name_ being defined.
870
871 2003-02-03 Paul Eggert <eggert@twinsun.com>
872
873 * src/gram.h (start_symbol): Remove unused decl.
874
875 Use more-consistent naming conventions for local vars.
876
877 * src/derives.c (derives_compute): Change type of local var from
878 int to rule_number.
879 * src/gram.c (grammar_rules_partial_print): Likewise.
880 * src/print.c (print_core): Likewise.
881 * src/reduce.c (reduce_grammar_tables): Likewise.
882
883 * src/gram.c (grammar_dump): Change name of item_number *
884 local var from r to rp.
885 * src/nullable.c (nullable_compute): Likewise.
886
887 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
888
889 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
890 for symbol or symbol_number var.
891 * src/reader.c (grammar_start_symbol_set): Likewise.
892 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
893 Likewise.
894 * src/state.c (transitions_to): Likewise.
895 * src/state.h: Likewise.
896 * src/tables.c (symbol_number_to_vector_number): Likewise.
897
898 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
899 char * var.
900
901 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
902 var.
903
904 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
905 var.
906
907 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
908 Use str, not s, for char * var. Use ch, not c, for character var.
909 Use size for size var.
910
911 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
912 char * var.
913 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
914 uniqstr var.
915 * src/uniqstr.h: Likewise.
916
917 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
918 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
919 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
920 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
921 param to have same name as that of enum, so that we don't use
922 "s" to stand for a non-state.
923
924 2003-02-02 Akim Demaille <akim@epita.fr>
925
926 * src/scan-skel.l: Scan more than one inert character per yylex
927 invocation.
928
929 2003-02-01 Paul Eggert <eggert@twinsun.com>
930
931 Version 1.875a.
932
933 * po/LINGUAS: Add ms.
934
935 2003-01-30 Akim Demaille <akim@epita.fr>
936
937 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
938
939 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
940
941 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
942 of $1.
943
944 Changes in response to error report by S. Eken: GLR mode does not
945 handle negative $ indices or $ indices in embedded rules correctly.
946 See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
947
948 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
949 (b4_rhs_location): Ditto.
950 (yyfill): New function to copy from stack tree into array
951 incrementally.
952 (yyuserAction): Modify to allow incremental move of semantic values
953 to rhs array when in GLR mode.
954 Define YYFILL to use in user-defined actions to fill semantic array
955 as needed.
956 Remove dummy use of yystack, as there is now a guaranteed use.
957 (yydoAction): Modify to allow incremental move of semantic values
958 to rhs array when in GLR mode.
959 (yyresolveAction): Ditto.
960 (yyglrShiftDefer): Update comment.
961 (yyresolveStates): Use X == NULL for pointers, not !X.
962 (yyglrReduce): Ditto.
963 (yydoAction): Ditto
964
965 * tests/glr-regr1.at: Rename to ...
966 * tests/glr-regression.at: Add new regression test for the problems
967 described above (adapted from S. Eken).
968 Update copyright notice.
969 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
970 * tests/Makefile.am: Ditto.
971
972 2003-01-28 Paul Eggert <eggert@twinsun.com>
973
974 * data/lalr1.cc: Do not use @output_header_name@ unless
975 b4_defines_flag is set. This fixes two bugs reported by
976 Tim Van Holder in
977 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
978 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
979
980 2003-01-21 Paul Eggert <eggert@twinsun.com>
981
982 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
983 we don't need to worry about yyerrlab1 being reported as an
984 "unused label" by non-GCC C compilers. The downside is that if
985 locations are used then a couple of statements are duplicated each
986 time YYERROR is invoked, but the upside is that the warnings
987 should vanish.
988 (yyerrlab1): Move code to YERROR.
989 (yyerrlab2): Remove. Change uses back to yyerrlab1.
990 This reverts some of the 2002-12-27 change.
991
992 2003-01-17 Paul Eggert <eggert@twinsun.com>
993
994 * src/output.c (symbol_printers_output): Fix typo that led
995 to core dump. Problem reported by Antonio Rus in
996 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
997
998 2003-01-13 Akim Demaille <akim@epita.fr>,
999 Quoc Peyrot <chojin@lrde.epita.fr>,
1000 Robert Anisko <anisko_r@lrde.epita.fr>
1001
1002 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
1003 when the stacks contain one element, as the loop would otherwise
1004 free the last state, and then use the top state (the one we just
1005 popped). This means that the initial elements will not be freed
1006 explicitly, as is the case in yacc.c; it is not a problem, as
1007 these elements have fake values.
1008
1009 2003-01-11 Paul Eggert <eggert@twinsun.com>
1010
1011 * NEWS: %expect-violations are now just warnings, reverting
1012 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
1013 bootstrapping problem reported by Matthias Klose; see
1014 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
1015 * src/conflicts.c (conflicts_print): Likewise.
1016 * tests/conflicts.at (%expect not enough, %expect too much,
1017 %expect with reduce conflicts): Likewise.
1018 * doc/bison.texinfo (Expect Decl): Document this. Also mention
1019 that the warning is enabled if the number of conflicts changes
1020 (not necessarily increases).
1021
1022 * src/getargs.c (version): Update copyright year.
1023
1024 2003-01-09 Akim Demaille <akim@epita.fr>
1025
1026 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
1027
1028 2003-01-08 Paul Eggert <eggert@twinsun.com>
1029
1030 * Makefile.maint (WGETFLAGS):
1031 New macro, containing "-C off" to disable proxy caches.
1032 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
1033 (rel-check): Use $(WGET) instead of wget.
1034
1035 2003-01-06 Paul Eggert <eggert@twinsun.com>
1036
1037 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
1038 the GLR paper of Scott, Johnstone and Hussain.
1039
1040 2003-01-04 Paul Eggert <eggert@twinsun.com>
1041
1042 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
1043 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
1044 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
1045 (EXTRA_LIBRARIES): New var, for liby.a.
1046 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
1047 (EXTRA_SCRIPTS): New var, for yacc.
1048
1049 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
1050 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
1051 Problem reported by Nelson H. F. Beebe.
1052
1053 2003-01-03 Paul Eggert <eggert@twinsun.com>
1054
1055 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
1056 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
1057 when compiling Bison 1.875's `bitset bset = obstack_alloc
1058 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
1059
1060 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
1061 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
1062 grow to a huge size with typical invocation.
1063
1064 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
1065 Use the pattern recommended by Autoconf 2.57, except also protect
1066 against double-definition.
1067 * src/system.h: Likewise.
1068 Portability issues reported by Nelson H. F. Beebe.
1069
1070 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
1071 All uses changed. Provide a definition in both C and C++.
1072 (yytrue, yyfalse): Define even if defined (__cplusplus).
1073
1074 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
1075 Reported by Nelson H. F. Beebe.
1076
1077 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
1078
1079 2003-01-02 Paul Eggert <eggert@twinsun.com>
1080
1081 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
1082 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
1083 Bug reported by Nelson H. F. Beebe.
1084
1085 2003-01-01 Paul Eggert <eggert@twinsun.com>
1086
1087 * Version 1.875.
1088
1089 2002-12-30 Paul Eggert <eggert@twinsun.com>
1090
1091 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
1092 Moved here from...
1093 (<INITIAL>","): Here. This causes stray "," to be treated
1094 more uniformly.
1095
1096 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
1097 last brace in braced code when not in Yacc mode, for compatibility
1098 with Bison 1.35. This resurrects the 2001-12-15 patch to
1099 src/reader.c.
1100
1101 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
1102 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
1103
1104 2002-12-28 Paul Eggert <eggert@twinsun.com>
1105
1106 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
1107 that of SYM's type. This fixes Debian bug 168069, reported by
1108 Thomas Olsson.
1109
1110 2002-12-28 Paul Eggert <eggert@twinsun.com>
1111
1112 Version 1.75f.
1113
1114 Switch back to the Yacc style of conflict reports, undoing some
1115 of the 2002-07-30 change.
1116 * doc/bison.texinfo (Understanding): Use Yacc style for
1117 conflict reports. Also, use new way of locating rules.
1118 * src/conflicts.c (conflict_report):
1119 Renamed from conflict_report_yacc, removing the old
1120 'conflict_report'. Translate the entire conflict report at once,
1121 so that we don't assume that "," has the same interpretation in
1122 all languages.
1123 (conflicts_output): Use Yacc-style conflict report for each state,
1124 instead of our more-complicated style.
1125 (conflicts_print): Use Yacc-style conflict report, except print
1126 the input file name when not emulating Yacc.
1127 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
1128 Conflicted Reduction, %expect not enough, %expect too much,
1129 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
1130 * tests/existing.at (GNU Cim Grammar): Likewise.
1131 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
1132
1133 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
1134 fatal): Don't invoke fflush; it's not needed and it might even be
1135 harmful for stdout, as stdout might not be open.
1136 * src/reduce.c (reduce_print): Likewise.
1137
1138 2002-12-27 Paul Eggert <eggert@twinsun.com>
1139
1140 Fix a bug where error locations were not being recorded correctly.
1141 This problem was originally reported by Paul Hilfinger in
1142 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
1143
1144 * data/yacc.c (yyparse): New local var yylerrsp, to record the
1145 top of the location stack's error locations.
1146 (yyerrlab): Set it. When discarding a token, push its location
1147 onto yylerrsp so that we don't lose track of the error's end.
1148 (yyerrlab1): Now is only the target of YYERROR, so that we can
1149 properly record the location of the action that failed. For GCC
1150 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
1151 GCC warning about yyerrlab1 being unused if YYERROR is unused.
1152 (yyerrlab2): New label, which yyerrlab now falls through to.
1153 Compute the error's location by applying YYLLOC_DEFAULT to
1154 the locations of all the symbols that went into the error.
1155 * doc/bison.texinfo (Location Default Action): Mention that
1156 YYLLOC_DEFAULT is also invoked for syntax errors.
1157 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
1158 Error locations include the locations of all the tokens that were
1159 discarded, not just the last token.
1160
1161 2002-12-26 Paul Eggert <eggert@twinsun.com>
1162
1163 * src/files.c: Include quote.h.
1164 (compute_output_file_names): Warn if we detect conflicting
1165 outputs to the same file. This should catch the misunderstanding
1166 exemplified by Debian Bug 165349, reported by Bruce Stephens..
1167
1168 * src/conflicts.c (conflicts_print): If the user specifies
1169 "%expect N", report an error if there are any reduce/reduce
1170 conflicts. This is what the manual says should happen.
1171 This fixes Debian bug 130890, reported by Anthony DeRobertis.
1172 * tests/conflicts.at (%expect with reduce conflicts): New test.
1173
1174 Don't use m4_include on relative file names, as it doesn't work as
1175 desired if there happens to be a file with that name under ".".
1176
1177 * m4sugar/version.m4: Remove; it was included but it wasn't used.
1178 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
1179 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
1180 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
1181 * src/output.c (output_skeleton): Use full path names when
1182 specifying a file to include; don't rely on include path, as
1183 it's unreliable when the working file contains a file with
1184 that name.
1185
1186 2002-12-25 Paul Eggert <eggert@twinsun.com>
1187
1188 Remove obsolete references to bison.simple and bison.hairy.
1189 Problem mentioned by Aubin Mahe in
1190 <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
1191 * data/glr.c: Comment fix.
1192 * doc/bison.1: Remove references. Also, mention "yacc".
1193
1194 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
1195 with -g option.
1196
1197 * src/parse-gram.y (declaration): Use enum "report_states" rather
1198 than its numeric value 1.
1199
1200 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
1201 opening a new one. This fixes Debian bug 165349, reported by
1202 Bruce Stephens.
1203
1204 2002-12-24 Paul Eggert <eggert@twinsun.com>
1205
1206 Version 1.75e.
1207
1208 * Makefile.maint (cvs-update): Don't assume that the shell
1209 supports $(...), as Solaris sh doesn't.
1210
1211 * src/parse-gram.y (lloc_default): Remove test for empty
1212 nonterminals at the end, since it didn't change the result.
1213
1214 2002-12-24 Paul Eggert <eggert@twinsun.com>
1215
1216 If the user does not define YYSTYPE as a macro, Bison now declares it
1217 using typedef instead of defining it as a macro. POSIX requires this.
1218 For consistency, YYLTYPE is also declared instead of defined.
1219
1220 %union directives can now have a tag before the `{', e.g., the
1221 directive `%union foo {...}' now generates the C code
1222 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
1223 The default union tag is `YYSTYPE', for compatibility with Solaris 9
1224 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
1225 instead of `yyltype'.
1226
1227 `yystype' and `yyltype' are now obsolescent macros instead of being
1228 typedefs or tags; they are no longer documented and will be
1229 withdrawn in a future release.
1230
1231 * data/glr.c (b4_location_type): Remove.
1232 (YYSTYPE): Renamed from yystype.
1233 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
1234 (struct YYLTYPE): Renamed from struct yyltype.
1235 (YYLTYPE): Renamed from yyltype.
1236 (yyltype, yystype): New (and obsolescent) macros,
1237 for backward compatibility.
1238 * data/yacc.c: Likewise.
1239
1240 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
1241 does not specify a union tag. This is for compatibility with
1242 Solaris 9 yacc.
1243
1244 * src/parse-gram.y (add_param): 2nd arg is now char * not char
1245 const *, since it is now modified by stripping surrounding { }.
1246 (current_braced_code): Remove.
1247 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
1248 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
1249 trailing " {...}". Now of type <chars>.
1250 (grammar_declaration): Adjust to bundled tokens.
1251 (code_content): Remove; stripping is now done by add_param.
1252 (print_token_value): Print contents of bundled tokens.
1253 (token_name): New function.
1254
1255 * src/reader.h (braced_code, current_braced_code): Remove.
1256 (token_name): New decl.
1257
1258 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
1259 token_type, not braced_code code_kind. All uses changed.
1260 (SC_PRE_CODE): New state, for scanning after a keyword that
1261 has (or usually has) an immediately-following braced code.
1262 (token_type): New local var, to keep track of which token type
1263 to return when scanning braced code.
1264 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
1265 <INITIAL>"%parse-param", <INITIAL>"%printer",
1266 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
1267 instead of returning a token type immediately.
1268 (<INITIAL>"{"): Set token type.
1269 (<SC_BRACED_CODE>"}"): Use it.
1270 (handle_action_dollar, handle_action_at): Now returns bool
1271 indicating success. Fail if ! current_rule; this prevents a core dump.
1272 (handle_symbol_code_dollar, handle_symbol_code_at):
1273 Remove; merge body into caller.
1274 (handle_dollar, handle_at): Complain in invalid contexts.
1275
1276 * NEWS, doc/bison.texinfo: Document the above.
1277 * NEWS: Fix years and program names in copyright notice.
1278
1279 2002-12-17 Paul Eggert <eggert@twinsun.com>
1280
1281 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
1282 Reporting, Table of Symbols): Omit mentions of %lex-param and

1287 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
1288 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
1289 lookahead symbol, and which sets yychar in parser actions) and it
1290 disagreed with the Bison documentation. Bug
1291 reported by Andrew Walrond.
1292
1293 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
1294 as the caller now does that.
1295 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
1296 (YYEMPTY): Parenthesize right hand side, since others use it.
1297 (yyparse): Don't assume that our generated code is the only code
1298 that sets yychar.

1300 2002-12-13 Paul Eggert <eggert@twinsun.com>
1301

1326 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
1327 locations are requested.
1328 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
1329 locations are requested.
1330
1331 2002-12-12 Paul Eggert <eggert@twinsun.com>
1332
1333 Remove unportable casts and storage allocation tricks.
1334 While we're at it, remove almost all casts, since they
1335 usually aren't needed and are a sign of trouble.
1336
1337 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
1338
1339 * src/derives.c (derives_compute): Do not subtract NTOKENS from
1340 the pointer DSET returned by malloc; this isn't portable.
1341 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
1342 Similarly for DERIVES.
1343 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
1344 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
1345 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
1346
1347 * src/derives.c (derives_compute): Do not bother invoking
1348 int_of_rule_number, since rule numbers are integers.
1349
1350 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
1351 rather than XMALLOC (char, N).
1352

1354
1355 * src/gram.h (symbol_number_as_item_number,
1356 item_number_as_symbol_number, rule_number_as_item_number,
1357 item_number_as_rule_number):
1358 Now inline functions rather than macros, to avoid casts.
1359 * src/state.h (state_number_as_int): Likewise.
1360 * src/tables.c (state_number_to_vector_number,
1361 symbol_number_to_vector_number): Likewise.
1362
1363 * src/gram.h (int_of_rule_number): Remove; no longer used.
1364
1365 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
1366 since the resulting storage is always stored into.
1367
1368 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
1369 where it's needed.
1370
1371 * src/muscle_tab.c (muscle_m4_output):
1372 Now inline. Return bool, not int.
1373 * src/state.c (state_compare): Likewise.

1382 * src/symtab.c (symbol_check_defined_processor,
1383 symbol_check_alias_consistency_processor, symbol_pack_processor,
1384 symbol_translation_processor, hash_symbol_comparator,
1385 hash_symbol_hasher): Likewise.
1386 * src/uniqstr.c (uniqstr_print_processor): Likewise.
1387 * src/muscle_tab.c (muscles_m4_output):
1388 Use new functions instead of casting old functions unportably.
1389 * src/state.c (state_hash_new): Likewise.
1390 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
1391 symbols_token_translations_init):
1392 Likewise.
1393 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
1394
1395 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
1396 var instead of casting to long, to avoid casts.
1397 (prepare_states): Use MALLOC rather than alloca, so that we don't
1398 have to worry about alloca.
1399 * src/state.c (state_hash_lookup): Likewise.
1400
1401 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
1402 local var instead of casting to unsigned char, to avoid casts.
1403
1404 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
1405 STATE_ALLOC): Remove.
1406 (transitions_new, errs_new, reductions_new, state_new): Use malloc
1407 rather than calloc, and use offsetof to avoid allocating slightly
1408 too much storage.
1409 (state_new): Initialize all members.
1410
1411 * src/state.c (state_hash): Use unsigned accumulator, not signed.
1412
1413 * src/symtab.c (symbol_free): Remove; unused.
1414 (symbol_get): Remove cast in lhs of assignment.
1415 (symbols_do): Now static. Accept generic arguments, not
1416 hashing-related ones.
1417
1418 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
1419 (symbol_processor): Remove.
1420 (symbols_do): Remove decl; now static.
1421
1422 * src/system.h (alloca): Remove; decl no longer needed.
1423 (<stddef.h>): Include, for offsetof.
1424 (<inttypes.>, <stdint.h>): Include if available.
1425 (uintptr_t): New type, if system lacks it.
1426 (CALLOC, MALLOC, REALLOC): New macros.
1427 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
1428 new macros.
1429
1430 * src/tables.c (table_size): Now int, to pacify GCC.
1431 (table_grow, table_ninf_remap): Use signed table size.

1435
1436 * src/vcg.h: Correct misspellings.
1437
1438 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
1439
1440
1441 * src/getargs.c (getargs): Don't assume EOF == -1.
1442
1443 2002-12-09 Paul Eggert <eggert@twinsun.com>
1444
1445 Change identifier spellings to avoid collisions with names
1446 that are reserved by POSIX.
1447
1448 Don't use names ending in _t, since POSIX reserves them.
1449 For consistency, remove _e and _s endings -- they're weren't
1450 needed to remove ambiguity. All uses changed.
1451 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
1452 turn was just renamed from struniq_t.
1453 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
1454 which in turn was just renamed from struniq_processor_t.

1526 value_t_as_yystype -> value_as_yystype.
1527
1528 Don't include <errno.h> in the mainstream code, since it

1530 * lib/get-errno.c, lib/get-errno.h: New files.
1531 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
1532 get-errno.c.

1546 likewise for "STRUNIQ" and "UNIQSTR".
1547 * src/uniqstr.c: Renamed from src/struniq.c.
1548 * src/uniqstr.h: Renamed from src/struniq.h.

1584 for consistency with other names.
1585 * lib/timevar.h (timevar_report): New decl.
1586 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
1587
1588
1589 Sort include-file uses.
1590
1591 Reorder all include files under src to be in the order "system.h".
1592 then the ../lib include files in angle brackets (alphabetized),
1593 then the . include files in double-quotes (alphabetized). Fix
1594 dependency breakages encountered in this process, as follows:
1595 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
1596 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
1597 * src/state.h: Include "symtab.h".
1598
1599 2002-12-08 Paul Eggert <eggert@twinsun.com>
1600
1601 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
1602 since this causes problems when __file__ contains character
1603 sequences like "@" that are treated specially by src/scan-skel.l.
1604 Instead, just use the file's basename. This fixes the bug
1605 reported by Martin Mokrejs in
1606 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
1607
1608 2002-12-06 Paul Eggert <eggert@twinsun.com>
1609
1610 Add support for rules that do not have trailing semicolons, as
1611 POSIX requires. Improve the quality of locations in Bison
1612 diagnostics.
1613
1614 * src/location.c: Include <quotearg.h>.
1615 (empty_location): Now const.
1616 (location_print): New function. Follow the recommendation of the

1618 * src/location.h: Do not include <quotearg.h>; no longer needed.
1619 (boundary): New type.
1620 (location_t): Use it. This allows locations to span file boundaries.
1621 All member uses changed: file -> start.file or end.file (as needed),
1622 first_line -> start.line, first_column -> start.column,
1623 last_line -> end.line, last_column -> end.column.
1624 (equal_boundaries): New function.
1625 (LOCATION_RESET, LOCATION_STEP): Remove.
1626 (LOCATION_PRINT): Remove. All callers changed to use location_print.
1627 (empty_location): Now const.
1628 (location_print): New decl.
1629 * src/parse-gram.y (lloc_default): New function, which handles
1630 empty locations more accurately.
1631 (YYLLOC_DEFAULT): Use it.
1632 (%token COLON): Remove.
1633 (%token ID_COLON): New token.
1634 (rules): Use it.

1640 (semi_colon.opt): Remove.
1641 * src/reader.h: Include location.h.
1642 (scanner_cursor): New decl.

1644 rolling our own.
1645 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
1646 of *loc.
1647 (STEP): Remove. No longer needed, now that adjust_location does
1648 the work. All uses removed.
1649 (scanner_cursor): New var.
1650 (adjust_location): Renamed from extend_location. It now sets
1651 *loc and adjusts the scanner cursor. All uses changed.
1652 Don't bother testing for CR.
1653 (handle_syncline): Remove location arg; now updates scanner cursor.
1654 All callers changed.
1655 (unexpected_end_of_file): Now accepts start boundary of token or
1656 comment, not location. All callers changed. Update scanner cursor,
1657 not the location.
1658 (SC_AFTER_IDENTIFIER): New state.
1659 (context_state): Renamed from c_context. All uses changed.
1660 (id_loc, code_start, token_start): New local vars.
1661 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
1662 processing of Yacc white space and equivalents here.
1663 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
1664 instead of returning ID immediately, since we need to search for
1665 a subsequent colon.
1666 (<INITIAL>"'", "\""): Save token_start.
1667 (<INITIAL>"%{", "{", "%%"): Save code_start.
1668 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
1669 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
1670 BEGIN context_state at end, not INITIAL.
1671 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
1672 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
1673 Return correct token start.
1674 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
1675 the start of a character, string or multiline comment is found.
1676 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
1677 Reduction): Adjust reported locations to match the more-precise
1678 results now expected.
1679 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
1680 * tests/reduce.at (Useless Rules, Reduced Automaton,
1681 Underivable Rules): Likewise.
1682 * tests/regression.at (Invalid inputs): No longer `expecting ";"
1683 or "|"' now that so many other tokens are allowed by the new grammar.
1684
1685 * src/complain.h (current_file): Remove duplicate decl;
1686 current_file is now owned by files.h.
1687 * src/complain.c, src/scan-gram.l: Include files.h.
1688
1689 2002-12-06 Paul Eggert <eggert@twinsun.com>
1690
1691 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
1692 promotes to int; it might be unsigned int.
1693 * data/yacc.c (yy_reduce_print): Likewise.
1694
1695 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
1696 be #defined in the prologue, not in the Bison declarations.
1697 This fixes Debian Bug 102878, reported by Shaul Karl.
1698
1699 2002-12-02 Paul Eggert <eggert@twinsun.com>
1700
1701 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
1702 * lib/strtoul.c: New file, from gnulib.
1703 This fixes a porting bug reported by Peter Klein in
1704 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
1705
1706 2002-11-30 Paul Eggert <eggert@twinsun.com>
1707
1708 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
1709 and put only a forward declaration in the prologue. This is for
1710 consistency with the other scanner helper functions.
1711
1712 Type clashes now generate warnings, not errors, since it
1713 appears that POSIX may allow some grammars with type clashes.
1714 * src/reader.c (grammar_current_rule_check): Warn about
1715 type clashes instead of complaining.
1716 * tests/input.at (Type Clashes): Expect warnings, not complaints.
1717
1718 Add Yacc library, since POSIX requires it.
1719 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
1720 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
1721 * lib/main.c, lib/yyerror.c: New files.
1722
1723 gram_error can be static; it need not be extern.
1724 * src/reader.h (gram_error): Remove decl.
1725 * src/parse-gram.y (gram_error): Now static. Add static decl.
1726 (print_token_value): Omit parameter names from forward decl,
1727 for consistency.
1728
1729 2002-11-29 Paul Eggert <eggert@twinsun.com>
1730
1731 * doc/bison.texinfo: Emphasize that yylex and yyerror must
1732 be declared before being used. E.g., one should typically
1733 declare them in the prologue. Use GNU coding style in examples.
1734 Put "const" consistently after the type it modifies. Mention
1735 that C99 supports "inline". Mention that yyerror traditionally
1736 returns "int".
1737
1738 %parse-param and %lex-param now take just one argument, the
1739 declaration; the argument name is deduced from the declaration.
1740
1741 * doc/bison.texinfo (Parser Function, Pure Calling, Error
1742 Reporting, Table of Symbols): Document this.
1743 * src/parse-gram.y (add_param): New function.
1744 (COMMA): Remove.
1745 (declaration): Implement new rule for %parse-param and %lex-param.
1746 * src/scan-gram.l: "," now elicits a warning, rather than being
1747 a token; this is more compatible with byacc.
1748 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
1749
1750 2002-11-27 Paul Eggert <eggert@twinsun.com>
1751
1752 Rename identifiers to avoid real and potential collisions.
1753
1754 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
1755 to avoid collision with lex macro described by Bruce Lilly in
1756 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
1757 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
1758 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
1759 * src/parse-gram.y (print_token_value): Renamed from yyprint.
1760 All uses changed.
1761 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
1762 The name "yycontrol" violates the name space rules, and this stuff
1763 wasn't being used anyway.
1764 (input): Remove action; this stuff wasn't being used.
1765 (gram_error): Rename local variable yylloc -> loc.
1766 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
1767 (YY_DECL): Don't use "yy" at start of local variables.
1768 All uses changed, e.g., yylloc -> loc.
1769 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
1770 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
1771 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
1772 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
1773
1774 * src/parse-gram.y (gram_error): loc is now const *.
1775 * src/reader.h (gram_error): Likewise.
1776
1777 2002-11-24 Paul Eggert <eggert@twinsun.com>
1778
1779 Version 1.75c.
1780
1781 * tests/actions.at (Actions after errors): Use an output format
1782 more similar to that of the Printers and Destructors test.
1783 Test the position of the ';' token too.
1784 (Printers and Destructors): Likewise.
1785 (Printers and Destructors: %glr-parser): Remove for now, to avoid
1786 unnecessarily alarming people when the test fails.
1787
1788 * data/yacc.c (yyerrlab1): Move this label down, so that the
1789 parser does not discard the lookahead token if the user code
1790 invokes YYERROR. This change is required for POSIX conformance.
1791
1792 * lib/error.c: Sync with gnulib.
1793
1794 2002-11-22 Paul Eggert <eggert@twinsun.com>
1795
1796 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
1797 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
1798 * lib/xmalloc.c: Likewise.
1799
1800 2002-11-20 Paul Eggert <eggert@twinsun.com>
1801
1802 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
1803
1804 2002-11-20 Paul Eggert <eggert@twinsun.com>
1805
1806 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
1807 should use `if (! x) abort ();' rather than `assert (x);', and
1808 anyway it's one less thing to worry about configuring.
1809
1810 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
1811 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
1812 and replace all instances of assert with abort.
1813 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1814 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
1815
1816 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
1817 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
1818 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
1819 hash_find_entry, hash_rehash, hash_insert): Likewise.
1820 * src/conflicts.c (resolve_sr_conflict): Likewise.
1821 * src/lalr.c (set_goto_map, map_goto): Likewise.
1822 * src/nullable.c (nullable_compute): Likewise.
1823 * src/output.c (prepare_rules, token_definitions_output): Likewise.
1824 * src/reader.c (packgram, reader): Likewise.
1825 * src/state.c (state_new, state_free, state_transitions_set,
1826 state_reduction_find): Likewise.
1827 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
1828 symbol_pack): Likewise.
1829 * src/tables.c (conflict_row, pack_vector): Likewise.
1830 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
1831 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
1832 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
1833 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
1834
1835 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
1836 (ARGMATCH_CONSTRAINT): New macro.
1837 (ARGMATCH_ASSERT): Use it.
1838
1839 * src/system.h (verify): New macro.
1840 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
1841 rather than assert.
1842 * src/tables.c (tables_generate): Likewise.
1843
1844 * src/struniq.c (struniq_assert): Now returns void, and aborts
1845 if the assertion is false.
1846 (struniq_assert_p): Remove.
1847 * src/struniq.h: Likewise.
1848
1849 2002-11-18 Paul Eggert <eggert@twinsun.com>
1850
1851 * data/glr.c (yygetLRActions): Replace `yyindex' with
1852 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
1853 This fixes the regression with Sun ONE Studio 7 cc that I reported in
1854 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
1855
1856 2002-11-18 Akim Demaille <akim@epita.fr>
1857
1858 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
1859 space.
1860 From Tim Van Holder.
1861
1862 2002-11-17 Paul Eggert <eggert@twinsun.com>
1863
1864 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
1865 to "SyntaxError" for consistency with my 2002-11-15 change.
1866
1867 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
1868 not define to {}, since this breaks the common use of `YYDPRINTF
1869 ((...));' if a single statement is desired (e.g. before `else').
1870 Work around GCC warnings by surrounding corresponding calls with
1871 {} if needed.
1872 (yyhasResolvedValue): Remove unused function.
1873 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
1874 loop body.
1875 (yyreportSyntaxError): Renamed from yyreportParseError.
1876 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
1877 All uses changed.
1878 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
1879 extern when possible. Remove unused initializations.
1880
1881 2002-11-16 Akim Demaille <akim@epita.fr>
1882
1883 Augment the similarity between GLR and LALR traces.
1884
1885 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
1886 (YY_REDUCE_PRINT): New.
1887 (yyparse): Use them.
1888 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
1889 YYDPRINT here.
1890 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
1891 state reached after the reduction/recovery, since...
1892 (yyparse, yyprocessOneStack): Report the state we are entering in.
1893
1894 2002-11-16 Akim Demaille <akim@epita.fr>
1895
1896 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
1897 Add support for --trace=skeleton.
1898 * src/scan-skel.l: %option debug.
1899 Scan strings of non-@ or \n instead of character by character.
1900 (scan_skel): Handle trace_skeleton.
1901 (QPUTS): New.
1902 (@output_parser_name@, @output_header_name@): ``Restore'' their
1903 support (used to be M4 macros).
1904 * data/yacc.c: Quote larger chunks, a la glr.c.
1905 * data/lalr1.cc: Likewise.
1906 The header guards are no longer available, so use some other
1907 string than `YYLSP_NEEDED'.
1908
1909 2002-11-16 Akim Demaille <akim@epita.fr>
1910
1911 Make the ``Printers and Destructors'' test more verbose, taking
1912 `yacc.c''s behavior as (possibly wrong) reference.
1913
1914 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
1915 instead of fprint on stdout.
1916 Set and report the last_line of the symbols.
1917 Consistently display values and locations.
1918
1919 2002-11-16 Paul Eggert <eggert@twinsun.com>
1920
1921 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
1922
1923 2002-11-15 Paul Eggert <eggert@twinsun.com>
1924
1925 * tests/actions.at (Actions after errors): New test case.
1926
1927 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
1928 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
1929 tests/action.at, tests/calc.at, tests/conflicts.at,
1930 tests/cxx-type.at, tests/regression.at:
1931 "parse error" -> "syntax error" for POSIX compatibility.
1932 "parsing stack overflow..." -> "parser stack overflow" so
1933 that code matches Bison documentation.
1934
1935 2002-11-15 Akim Demaille <akim@epita.fr>
1936
1937 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
1938 take two BRACED_CODE, not two string_content.
1939 Free the scanner's obstack when we are done.
1940 (code_content): New.
1941 * tests/calc.at: Adjust.
1942 * doc/bison.texinfo: Adjust.
1943 Also, make sure to include the `,' for these declarations.
1944
1945 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
1946
1947 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
1948 definition; avoids potential autoreconf problems.
1949
1950 2002-11-15 Akim Demaille <akim@epita.fr>
1951
1952 Always check the value returned by yyparse.
1953
1954 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
1955 returned by yyparse.
1956 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
1957 Adjust calls.
1958 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
1959 returned by yyparse.
1960
1961 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1962
1963 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
1964 on input.at test.
1965
1966 2002-11-14 Paul Eggert <eggert@twinsun.com>
1967
1968 * src/output.c (output_skeleton): Call xfopen instead of
1969 duplicating xfopen's body.
1970
1971 Fix bugs reported by Nelson H. F. Beebe in
1972 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
1973
1974 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
1975 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
1976 Group compiler. Instead, use "$CC -E bar.c". Include the .h
1977 file twice in the grammar, as an extra check.
1978
1979 * tests/input.at (Torturing the Scanner): Surround the
1980 backslash-newline tests with "#if 0", to make it less likely that
1981 we'll run into compiler bugs. Bring back solitary \ inside
1982 comment, but add a closing comment to work around HP C bug. Don't
1983 test backslash-newline in C character constant.
1984
1985 2002-11-14 Akim Demaille <akim@epita.fr>
1986
1987 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
1988 status of the compiler.
1989 Calling `exit 1' is no longer needed.
1990 Reported by Nelson H. F. Beebe.
1991
1992 2002-11-14 Akim Demaille <akim@epita.fr>
1993
1994 * tests/atlocal.in (CPPFLAGS): We have config.h.
1995 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
1996 New.
1997 * tests/actions.at, tests/calc.at, tests/conflicts.at,
1998 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
1999 * tests/regression.at, tests/torture.at: Use them for all the
2000 grammars that are to be compiled.
2001 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
2002 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
2003 * doc/bison.texinfo (GLR Parsers): Document `inline'.
2004
2005 2002-11-14 Akim Demaille <akim@epita.fr>
2006
2007 * doc/bison.texinfo: Various formatting changes (alignments in
2008 samples, additional @group/@end group, GCS in samples.
2009 Use @deffn instead of simple @table to define the directives,
2010 macros, variables etc.
2011
2012 2002-11-13 Paul Eggert <eggert@twinsun.com>
2013
2014 Fix some bugs reported by Albert Chin-A-Young in
2015 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
2016
2017 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
2018 -o c"; the HP C compiler chatters during compilation.
2019 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
2020 * tests/headers.at (export YYLTYPE): Likewise.
2021
2022 * tests/input.at (Torturing the Scanner): Remove lines containing
2023 solitary backslashes, as they tickle a bug in the HP C compiler.
2024
2025 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
2026 comments, since they're not portable. Use GNU coding style.
2027
2028 2002-11-13 Akim Demaille <akim@epita.fr>
2029
2030 * data/yacc.c: Leave bigger chunks of quoted text.
2031 (YYDSYMPRINTF): New.
2032 Use it to report symbol activities.
2033 * data/glr.c (YYDSYMPRINTF): New.
2034 Use it.
2035
2036 2002-11-12 Paul Eggert <eggert@twinsun.com>
2037
2038 Version 1.75b.
2039
2040 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
2041 (yyglrReduce): Return yyok, not 0.
2042 This should avoid the enumerated-type warnings reported
2043 by Nelson H. F. Beebe in
2044 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
2045
2046 * lib/bbitset.h (BITSET_INLINE): Remove.
2047 * lib/bitset.h [! BITSET_INLINE]: Remove.
2048 (bitset_set, bitset_reset, bitset_test): Rename local vars
2049 to avoid shadowing warnings by GCC.
2050
2051 * data/glr.c (inline): Remove #define. It's the user's
2052 responsibility to #define it away, just like 'const'.
2053 This fixes one of the bugs reported by Nelson H. F. Beebe in
2054 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
2055
2056 * Makefile.maint (po-check): Scan .l and .y files instead of the
2057 .c and the .h files that they generate. This fixes the bug
2058 reported by Tim Van Holder in:
2059 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
2060 Look for N_ as well as for _. Try to avoid matching #define for
2061 N_ and _.
2062 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
2063 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
2064 * src/scan-gram.l: Revamp regular expressions so that " and '
2065 do not confuse xgettext.
2066
2067 * src/struniq.h (struniq_new): Do not declare the return type
2068 to be 'const'; this violates the C standard.
2069 * src/struniq.c (struniq_new): Likewise.
2070
2071 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
2072
2073 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
2074 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
2075 linker.
2076
2077 2002-11-12 Akim Demaille <akim@epita.fr>
2078
2079 * Makefile.maint: Sync with Autoconf:
2080 (local_updates): New.
2081
2082 2002-11-12 Akim Demaille <akim@epita.fr>
2083
2084 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
2085
2086 2002-11-12 Akim Demaille <akim@epita.fr>
2087
2088 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
2089 locations.
2090
2091 2002-11-12 Akim Demaille <akim@epita.fr>
2092
2093 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
2094 not yyvalue.
2095
2096 2002-11-12 Akim Demaille <akim@epita.fr>
2097
2098 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
2099 Use it to test the GLR parser.
2100
2101 2002-11-12 Akim Demaille <akim@epita.fr>
2102
2103 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
2104 defines it.
2105 * data/glr.c (yystos): New.
2106 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
2107 (YYDSYMPRINT): New.
2108 (yyval): Don't define it, it is handled via M4.
2109 (yyrecoverParseError): Free verbosely the discarded symbols.
2110 * data/yacc.c (yysymprint): Remove, rather...
2111 (b4_yysymprint_generate): invoke.
2112 * data/c.m4 (b4_yysymprint_generate): New.
2113 Accept pointers as arguments, as opposed to the version from
2114 yacc.c.
2115 (b4_yydestruct_generate): Likewise.
2116 * tests/cations.at (Printers and Destructors): Use Bison directives
2117 instead of CPP macros.

2122 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
2123 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
2124 Don't work on yychar (i.e., do set it to YYEMPTY, don't match

2126 it to YYEMPTY etc.).
2127 (yydestruct): Replace with a b4_yydestruct_generate invocation.
2128 (b4_symbol_actions): Remove.
2129 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands

2133
2134 * doc/bison.texinfo (Destructor Decl): New.
2135
2136 2002-11-12 Akim Demaille <akim@epita.fr>
2137
2138 * src/tables.c (tables_generate): Use free for pointers that

2146
2147 2002-11-12 Akim Demaille <akim@epita.fr>
2148
2149 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
2150 Restore.
2151 * src/scan-gram.l (last_string): Is global to the file, not to
2152 yylex.
2153 * src/parse-gram.y (input): Don't append the epilogue here,
2154 (epilogue.opt): do it here, and free the scanner's obstack.
2155 * src/reader.c (epilogue_set): Rename as...
2156 (epilogue_augment): this.
2157 * data/c.m4 (b4_epilogue): Defaults to empty.
2158
2159 2002-11-12 Akim Demaille <akim@epita.fr>
2160
2161 * src/getargs.c (long_options): Remove duplicates.

2166
2167 2002-11-12 Akim Demaille <akim@epita.fr>
2168
2169 * src/struniq.h, src/struniq.c (struniq_t): Is const.
2170 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
2171
2172 Use struniq for symbols.
2173
2174 * src/symtab.h (symbol_t): The tag member is a struniq.
2175 (symbol_type_set): Adjust.
2176 * src/symtab.c (symbol_new): Takes a struniq.
2177 (symbol_free): Don't free the tag member.

2200 Don't free the input file name.
2201
2202 2002-11-12 Akim Demaille <akim@epita.fr>
2203

2214
2215 2002-11-11 Paul Eggert <eggert@twinsun.com>
2216
2217 Revamp to fix many (but not all) of the C- and M4-related quoting
2218 problems. Among other things, this fixes the Bison bug reported
2219 by Jan Hubicka when processing the Bash grammar; see:
2220 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
2221
2222 Use new @ escapes consistently. Represent brackets with @{ and @}
2223 rather than @<:@ and @:>@, since this works a bit better with dumb
2224 editors like vi. Represent @ with @@, since @ is now consistently
2225 an escape. Use @oline@ and @ofile@ rather than __oline__ and
2226 __ofile__, to avoid unexpected expansions. Similarly, use @output
2227 rather than #output.
2228
2229 * data/c.m4 (b4_copyright): Omit file name from comment, since
2230 the file name could contain "*/".
2231 (b4_synclines_flag): Don't quote the 2nd argument; it should already
2232 be quoted. All uses changed.
2233
2234 * data/glr.c: Use new @ escapes consistently.
2235 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
2236 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
2237 Remove, since they couldn't handle arbitrary characters in file
2238 names.
2239 * data/lalr1.cc: Likewise.
2240 * data/yacc.c: Likewise.
2241
2242 * src/files.c (output_infix): Remove; all uses removed.
2243 * src/files.h: Likewise.
2244
2245 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
2246 mishandled funny characters in file names, and anyway it isn't
2247 needed any more.
2248 * data/yacc.c: Likewise.
2249 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
2250
2251 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
2252 * data/yacc.c: Likewise.
2253
2254 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
2255 strings now.
2256 (muscle_init): Quote filename as a C string.
2257 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
2258 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
2259 * src/output.c (escaped_file_name_output): New function.
2260 (prepare_symbols): Quote tokens for M4.
2261 (prepare): Don't insert output_infix, output_prefix,
2262 output_parser_name, output_header_name; this is now down by scan-skel.
2263 Insert skeleton as a C string.
2264
2265 * src/output.c (user_actions_output, symbol_destructors_output,
2266 symbol_printers_output): Quote filenames for C and M4.
2267 * src/reader.c (prologue_augment, epilogue_set): Likewise.
2268
2269 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
2270 escapes other than \\ and \'; this simplifies the code.
2271 (<SC_STRING>): Likewise, for \\ and \".
2272 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
2273 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
2274 Use new escapes @{ and @} for [ and ].
2275
2276 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
2277 them with auto vars.
2278 Switch to new escape scheme, where @ is the escape character uniformly.
2279 Abort if a stray escape character is found. Avoid unbounded input
2280 buffer when parsing non-escaped text.
2281
2282 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
2283 __oline__, #output, $@, and @{ do not have unintended meanings.
2284
2285 2002-11-09 Paul Eggert <eggert@twinsun.com>
2286
2287 Fix the test failure due to GCC warnings described in
2288 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
2289 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
2290 evaluate to 0 if it's impossible for NINF to be in the respective
2291 table.
2292 (yygetLRActions, yyrecoverParseError): Use them.
2293
2294 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
2295 counted in the token inserted at end of file. Now takes
2296 location_t *, not location_t, so that the location can be
2297 adjusted. All uses changed.
2298
2299 * tests/regression.at (Invalid inputs): Adjust wording in
2300 diagnostic to match the new behavior.
2301
2302 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
2303 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
2304 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
2305 abort ();'. This reduces the runtime of the "Many lookaheads"
2306 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
2307 GCC 3.2.
2308
2309 2002-11-07 Paul Eggert <eggert@twinsun.com>
2310
2311 * src/parse-gram.y (CHARACTER): Remove unused token.
2312 All uses removed.
2313
2314 * src/scan-gram.l: Remove stack option. We no longer use the
2315 stack, since the stack was never deeper than 1; instead, use the
2316 new auto var c_context to record the stacked value.
2317
2318 Remove nounput option. At an unexpected end of file, we now unput
2319 the minimal input necessary to end cleanly; this simplifies the
2320 code.
2321
2322 Avoid unbounded token sizes where this is easy.
2323
2324 (unexpected_end_of_file): New function.
2325 Use it to systematize the error message on unexpected EOF.
2326 (last-string): Now auto, not static.
2327 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
2328 (scanner_last_string_free): Remove; not used.
2329 (percent_percent_count): Move decl to just before use.
2330 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
2331 not the (never otherwised-used) CHARACTER.
2332
2333 2002-11-07 Akim Demaille <akim@epita.fr>
2334
2335 Let yyerror always receive the msg as last argument, so that
2336 yyerror can be variadic.
2337
2338 * data/yacc.c (b4_yyerror_args): New.
2339 Use it when calling yyerror.
2340 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
2341 Use it when calling yyerror.
2342 * doc/bison.texinfo (Error Reporting): Adjust.

2344 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
2345
2346 2002-11-06 Akim Demaille <akim@epita.fr>
2347
2348 #line should have quoted strings.
2349 Ideally, this should be done by m4_quotearg.
2350
2351 * src/scan-skel.l: Include quotearg.h.
2352 Quote __ofile__.
2353 * src/output.c (symbol_printers_output)
2354 (symbol_destructors_output): Quote the file name.
2355
2356 2002-11-06 Akim Demaille <akim@epita.fr>
2357
2358 * tests/regression.at (Invalid inputs): Adjust to the recent
2359 messages.
2360
2361 2002-11-06 Akim Demaille <akim@epita.fr>
2362
2363 Restore --no-lines.
2364 Reported by Jim Kent.
2365
2366 * data/c.m4 (b4_syncline): New.
2367 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
2368 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
2369 * src/output.c (user_actions_output): Likewise.
2370 (prepare): Define 'b4_synclines_flag'.
2371 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
2372
2373 2002-11-06 Akim Demaille <akim@epita.fr>
2374
2375 * src/main.c (main): Free `infile'.
2376 * src/scan-gram.l (handle_syncline): New.
2377 Recognize `#line'.
2378 * src/output.c (user_actions_output, symbol_destructors_output)
2379 (symbol_printers_output): Use the location's file name, not
2380 infile.
2381 * src/reader.c (prologue_augment, epilogue_set): Likewise.
2382
2383 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
2384
2385 * src/tables.c (matching_state): Don't allow states to match if
2386 either has GLR conflict entries.
2387
2388 2002-11-05 Paul Eggert <eggert@twinsun.com>
2389
2390 * src/scan-gram.l: Use more accurate diagnostics, e.g.
2391 "integer out of range" rather than "invalid value".
2392 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
2393 accordingly.
2394
2395 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
2396 Also, remove one static variable in the scanner.
2397
2398 * src/scan-gram.l (braces_level): Now auto, not static.
2399 Initialize to zero if the compiler is being picky.
2400 (INITIAL): Clear braces_level instead of incrementing it.
2401 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
2402 as POSIX 1003.1-2001 requires.
2403 * src/system.h (IF_LINT): New macro, taken from coreutils.
2404 * configure.ac: Define "lint" if --enable-gcc-warnings.
2405
2406 2002-11-05 Akim Demaille <akim@epita.fr>
2407
2408 * src/scan-gram.l: When it starts with `%', complain about the
2409 whole directive, not just that `invalid character: %'.
2410
2411 2002-11-04 Akim Demaille <akim@epita.fr>
2412
2413 * Makefile.maint: Update from Autoconf.

2422 returns true when location & yacc & pure & parse-param.
2423 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
2424
2425 2002-11-04 Akim Demaille <akim@epita.fr>
2426
2427 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
2428 clashes.
2429 * src/scan-gram.l: Use [\'] instead of ['] to pacify
2430 font-lock-mode.
2431 Use complain_at.
2432 Use quote, not quote_n since LOCATION_PRINT no longer uses the
2433 slot 0.
2434

2507 Use {splice} wherever C allows backslash-newline.
2508 YY_STEP after space, newline, vertical-tab.

2525 with quote slot used by complain_at.
2526
2527 * tests/input.at: Add tests for backslash-newline, m4 quotes
2528 in symbols, long literals, and funny escapes in strings.

2535
2536 * doc/bison.texinfo (Grammar Outline): Document // comments.
2537 (Symbols): Document that trigraphs have no special meaning in Bison,
2538 nor is backslash-newline allowed.
2539 (Actions): Document that trigraphs have no special meaning.
2540
2541 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
2542 no longer used.
2543
2544 2002-11-02 Paul Eggert <eggert@twinsun.com>
2545
2546 * src/reader.c: Don't include quote.h; not needed.
2547 (get_merge_function): Reword warning to be consistent with
2548 type clash diagnostic in grammar_current_rule_check.
2549
2550 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
2551 bug in trigraph handling.
2552
2553 * src/output.c (prepare_symbols): When printing token names,
2554 escape "[" as "@<:@" and likewise for "]".
2555
2556 * src/system.h (errno): Remove declaration, as we are now
2557 assuming C89 or better, and C89 guarantees errno.
2558
2559 2002-10-30 Paul Eggert <eggert@twinsun.com>
2560
2561 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
2562 Check for close failures.
2563 * src/files.h (xfclose): Return void, not int, since it always
2564 returned zero.
2565 * src/files.c (xfclose): Likewise. Report I/O error if ferror
2566 indicates one.
2567 * src/output.c (output_skeleton): Use xfclose rather than fclose
2568 and ferror. xfclose now checks ferror.
2569
2570 * data/glr.c (YYLEFTMOST_STATE): Remove.
2571 (yyreportTree): Use a stack-based leftmost state. This avoids
2572 our continuing battles with bogus warnings about initializers.
2573
2574 2002-10-30 Akim Demaille <akim@epita.fr>
2575
2576 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
2577 #if.
2578
2579 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
2580
2581 * tests/glr-regr1.at: New test for reported regressions.
2582 * tests/testsuite.at: Add glr-regr1.at test.
2583 * tests/Makefile.am: Add glr-regr1.at test.
2584
2585 2002-10-24 Paul Eggert <eggert@twinsun.com>
2586
2587 Version 1.75a.
2588
2589 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
2590 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
2591 we use malloc. Don't assume 'A' through 'Z' are contiguous.
2592 Don't assume strdup exists; POSIX says its an XSI extension.
2593 Check for buffer overflow on input.
2594
2595 2002-10-24 Akim Demaille <akim@epita.fr>
2596
2597 * src/output.c (output_skeleton): Don't disable M4sugar comments
2598 too soon: it results in comments being expanded.
2599 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
2600 first output.
2601
2602 2002-10-24 Akim Demaille <akim@epita.fr>
2603
2604 * data/yacc.c (m4_int_type): New.
2605 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
2606 char' as only yacc.c wants K&R portability.
2607 * data/glr.c (yysigned_char): Remove.
2608 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
2609 Reported by Quoc Peyrot.
2610
2611 2002-10-23 Paul Eggert <eggert@twinsun.com>
2612
2613 * src/main.c (main): With --trace=time, report times even if a
2614 non-fatal error occurs. Formerly, the times were reported in some
2615 such cases but not in others.
2616 * src/reader.c (reader): Just return if a complaint has been issued,
2617 instead of exiting, so that 'main' can report times.
2618
2619 2002-10-22 Akim Demaille <akim@epita.fr>
2620
2621 * src/system.h: Include sys/types.
2622 Reported by Bert Deknuydt.
2623
2624 2002-10-23 Paul Eggert <eggert@twinsun.com>
2625
2626 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
2627 Suggested by Art Haas.
2628
2629 2002-10-22 Paul Eggert <eggert@twinsun.com>
2630
2631 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
2632 decl; not needed any more.
2633 * src/main.c (main): Use return to exit, undoing yesterday's change.
2634 The last OS that we could find where this wouldn't work is
2635 SunOS 3.5, and that's too old to worry about now.
2636
2637 * data/glr.c (struct yyltype): Define members even when not
2638 doing locations. This is more consistent with yacc.c, and it
2639 works around the following bug reports:
2640 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
2641 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
2642
2643 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
2644 @acronym consistently. Standardize on "Yacc" instead of "YACC",
2645 "Algol" instead of "ALGOL". Give a bit more history about BNF.
2646
2647 2002-10-22 Akim Demaille <akim@epita.fr>
2648
2649 * data/README: New.
2650
2651 2002-10-21 Paul Eggert <eggert@twinsun.com>
2652
2653 Be consistent about 'bool'; the old code used an enum in one
2654 module and an int in another, and this violates the C standard.
2655 * m4/stdbool.m4: New file, from coreutils 4.5.3.
2656 * configure.ac (AC_HEADER_STDBOOL): Add.
2657 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
2658 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
2659 * src/symtab.c (hash_compare_symbol_t): Likewise.
2660 * src/system.h (bool, false, true): Use a definition consistent
2661 with ../lib/hash.c. All uses changed.
2662
2663 * src/complain.c (warning_issued): Renamed from warn_message_count,
2664 so that we needn't worry about integer overflow (!).
2665 Now of type bool. All uses changed.
2666 (complaint_issued): Renamed from complain_message_count; likewise.
2667
2668 * src/main.c (main): Use exit to exit with failure.
2669
2670 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
2671 rather than 1 and 0.
2672 * src/main.c (main): Likewise.
2673 * src/getargs.c (getargs): Likewise.
2674 * src/reader.c (reader): Likewise.
2675
2676 * src/getarg.c (getargs): Remove duplicate code for
2677 "Try `bison --help'".
2678
2679 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
2680 What was that "2" for?
2681
2682 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
2683 * src/getargs.c (usage): Likewise.
2684
2685 * src/getargs.c (getargs): When there are too few operands, report
2686 the last one. When there are too many, report the first extra
2687 one. This is how diffutils does it.
2688
2689 2002-10-20 Paul Eggert <eggert@twinsun.com>
2690
2691 Remove K&R vestiges.
2692 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
2693 * src/complain.c (VA_START): Remove. Assume prototypes.
2694 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
2695 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
2696 fatal): Assume prototypes.
2697 * src/complain.h: Assume prototypes.
2698 * src/system.h (PARAMS): Remove.
2699 Include <limits.h> unconditionally, since it's guaranteeed even
2700 for a freestanding C89 compiler.
2701 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
2702 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
2703
2704 2002-10-20 Akim Demaille <akim@epita.fr>
2705
2706 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
2707 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
2708 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
2709 (yyresolveStates, yyresolveAction, yyresolveStack)
2710 (yyprocessOneStack): Use them.
2711 (yy_reduce_print): New.
2712 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
2713
2714 2002-10-20 Akim Demaille <akim@epita.fr>
2715
2716 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
2717 arguments and output `void'.
2718 (b4_c_function): Rename as...
2719 (b4_c_function_def): this.
2720 (b4_c_function_decl, b4_c_ansi_function_def)
2721 (b4_c_ansi_function_decl): New.
2722 Change the interpretation of the arguments: before `int, foo', now
2723 `int foo, foo'.
2724 * data/yacc.c (yyparse): Prototype and define thanks to these.
2725 Adjust b4_c_function_def uses.
2726 * data/glr.c (yyparse): Likewise, but ANSI only.
2727
2728 2002-10-20 Akim Demaille <akim@epita.fr>
2729
2730 * src/output.c (prepare): Move the definition of `tokens_number',
2731 `nterms_number', `undef_token_number', `user_token_number_max'
2732 to...
2733 (prepare_tokens): Here.
2734 (prepare_tokens): Rename as...
2735 (prepare_symbols): this.
2736 (prepare): Move the definition of `rules_number' to...
2737 (prepare_rules): here.
2738 (prepare): Move the definition of `last', `final_state_number',
2739 `states_number' to...
2740 (prepare_states): here.
2741 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
2742
2743 2002-10-20 Akim Demaille <akim@epita.fr>
2744
2745 * src/tables.h, src/tables.c, src/output.c: Comment changes.
2746
2747 2002-10-20 Akim Demaille <akim@epita.fr>
2748
2749 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
2750 * data/c.m4: here.
2751
2752 2002-10-20 Akim Demaille <akim@epita.fr>
2753
2754 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
2755 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
2756 `pair'.
2757 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
2758 `name' to...
2759 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
2760 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
2761 These.
2762
2763 2002-10-19 Paul Eggert <eggert@twinsun.com>
2764
2765 Do not create a temporary file, as that involves security and
2766 cleanup headaches. Instead, use a pair of pipes.
2767 Derived from a suggestion by Florian Krohm.
2768 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
2769 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
2770 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
2771 (BISON_PREREQ_SUBPIPE): Add.
2772 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
2773 Add subpipe.h, subpipe.c.
2774 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
2775 * po/POTFILES.in: Add lib/subpipe.c.
2776 * src/output.c: Include "subpipe.h".
2777 (m4_invoke): Remove decl.
2778 (scan_skel): New decl.
2779 (output_skeleton): Use pipe rather than temporary file for m4 input.
2780 Check that m4sugar.m4 is readable, to avoid deadlock.
2781 Check for pipe I/O error.
2782 * src/scan-skel.l (readpipe): Remove decl.
2783 (scan_skel): New function, to be used in place of m4_invoke.
2784 Read from stream rather than file.
2785
2786 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
2787 float, as this generates a warning on Solaris 8 + GCC 3.2 with
2788 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
2789 this generates a more-accurate value anyway.
2790
2791 * lib/timevar.c (timervar_accumulate): Rename locals to
2792 avoid confusion with similarly-named more-global.
2793 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
2794
2795 * src/output.c (prepare): Use xstrdup to convert char const *
2796 to char *, to avoid GCC warning.
2797
2798 2002-10-19 Akim Demaille <akim@epita.fr>
2799
2800 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
2801 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
2802 Use them to have `calc.y' ready for %pure-parser.
2803 * data/yacc.c (YYLEX): Pass a yylex return type to
2804 b4_c_function_call.
2805
2806 2002-10-19 Akim Demaille <akim@epita.fr>
2807
2808 Prototype support of %lex-param and %parse-param.
2809
2810 * src/parse-gram.y: Add the definition of the %lex-param and
2811 %parse-param tokens, plus their rules.
2812 Drop the `_' version of %glr-parser.
2813 Add the "," token.
2814 * src/scan-gram.l (INITIAL): Scan them.
2815 * src/muscle_tab.c: Comment changes.
2816 (muscle_insert, muscle_find): Rename `pair' as `probe'.
2817 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
2818 (muscle_entry_s): The `value' member is no longer const.
2819 Adjust all dependencies.
2820 * src/muscle_tab.c (muscle_init): Adjust: use
2821 MUSCLE_INSERT_STRING.
2822 Initialize the obstack earlier.
2823 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
2824 (muscle_pair_list_grow): New.
2825 * data/c.m4 (b4_c_function_call, b4_c_args): New.
2826 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
2827 * tests/calc.at: Use %locations, not --locations.
2828 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
2829
2830 2002-10-19 Akim Demaille <akim@epita.fr>
2831
2832 * src/getargs.c (usage): Take status as argument and exit
2833 accordingly.
2834 Report the traditional `Try ... --help' message when status != 0.
2835 (usage, version): Don't take a FILE * as arg, it is pointless.
2836 (getargs): When there is an incorrect number of arguments, make it
2837 an error, and report it GNUlically thanks to `usage ()'.
2838
2839 2002-10-18 Paul Eggert <eggert@twinsun.com>
2840
2841 * data/glr.c (yyreportParseError): Don't assume that sprintf
2842 yields the length of the printed string, as this is not true
2843 on SunOS 4.1.4. Reported by Peter Klein.
2844
2845 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
2846 * tests/conflicts.at (%nonassoc and eof): Likewise.
2847 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
2848
2849 2002-10-17 Akim Demaille <akim@epita.fr>
2850
2851 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
2852 * src/getargs.c (trace_types, trace_args): Adjust.
2853 * src/reader.c (grammar_current_rule_prec_set)
2854 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
2855 Standardize error messages.
2856 And s/@prec/%prec/!
2857 (reader): Use trace_flag to enable scanner/parser debugging,
2858 instead of an adhoc scheme.
2859 * src/scan-gram.l: Remove trailing debugging code.
2860
2861 2002-10-16 Paul Eggert <eggert@twinsun.com>
2862
2863 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
2864 MUSCLE_TAB_H.
2865
2866 * NEWS: Officially drop support for building Bison with K&R C,
2867 since it didn't work anyway and it's not worth worrying about.
2868 * Makefile.maint (wget_files): Remove ansi2knr.c.
2869 (ansi2knr.c-url_prefix): Remove.
2870 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
2871 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
2872 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
2873
2874 2002-10-15 Paul Eggert <eggert@twinsun.com>
2875
2876 Stop using the "enum_" trick for K&R-style function definitions;
2877 it confused me, and I was the author! Instead, assume that people
2878 who want to use K&R C compilers (when using these modules in GCC,
2879 perhaps?) will run ansi2knr.
2880
2881 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
2882 All uses of "enum_" changed to "enum ".
2883 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
2884 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
2885
2886 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

2893 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
2894 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
2895 Use function prototypes; this removes the need for declaring
2896 static functions simply to provide their prototypes.
2897 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,
2898 bitset_andn_or_, bitset_andn_or_cmp_, bitset_bytes, bitset_copy_,

2924 bitsetv_zero, bitsetv_ones, bitsetv_transitive_closure,

2950 2002-10-14 Akim Demaille <akim@epita.fr>
2951
2952 Version 1.75.
2953
2954 2002-10-14 Akim Demaille <akim@epita.fr>
2955
2956 * tests/Makefile.am (maintainer-check-posix): New.
2957
2958 2002-10-14 Akim Demaille <akim@epita.fr>
2959
2960 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
2961 member.
2962
2963 2002-10-14 Akim Demaille <akim@epita.fr>
2964
2965 * src/tables.c (table_ninf_remap): base -> tab.
2966 Reported by Matt Rosing.
2967
2968 2002-10-14 Paul Eggert <eggert@twinsun.com>
2969
2970 * tests/action.at, tests/calc.at, tests/conflicts.at,
2971 tests/cxx-type.at, tests/headers.at, tests/input.at,
2972 tests/regression.at, tests/synclines.at, tests/torture.at:
2973 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
2974 so that the tests still work even if POSIXLY_CORRECT is set.
2975 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
2976
2977 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
2978 for portability to K&R hosts. Fix typo: signed char is guaranteed
2979 only to 127, not to 128.
2980 * data/glr.c (yysigned_char): New type.
2981 * data/yacc.c (yysigned_char): Likewise.
2982 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
2983
2984 2002-10-13 Paul Eggert <eggert@twinsun.com>
2985
2986 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
2987 true due to limited range of data type" warning from GCC.
2988
2989 * data/c.m4 (b4_token_defines): Protect against double-inclusion
2990 by wrapping enum yytokentype's definition inside #ifndef
2991 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
2992
2993 2002-10-13 Akim Demaille <akim@epita.fr>
2994
2995 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
2996 Un yy- yyrhs to avoid the name clash with the global YYRHS.
2997
2998 2002-10-13 Akim Demaille <akim@epita.fr>
2999
3000 * Makefile.maint: Update from Autoconf 2.54.
3001 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
3002
3003 2002-10-13 Akim Demaille <akim@epita.fr>
3004
3005 * src/print.c (print_state): Separate the list of solved conflicts
3006 from the other items.
3007 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
3008
3009 2002-10-13 Akim Demaille <akim@epita.fr>
3010
3011 Let nondeterministic skeletons be usable with deterministic
3012 tables.
3013
3014 With the patch, GAWK compiled by GCC without -O2 passes its test
3015 suite using a GLR parser driven by LALR tables. It fails with -O2
3016 because `struct stat' gives two different answers on my machine:
3017 88 (definition of an auto var) and later 96 (memset on this var).
3018 Hence the stack is badly corrumpted. The headers inclusion is to
3019 blame: if I move the awk.h inclusion before GLR's system header
3020 inclusion, the two struct stat have the same size.
3021
3022 * src/tables.c (pack_table): Always create conflict_table.
3023 (token_actions): Always create conflict_list.
3024 * data/glr.c (YYFLAG): Remove, unused.
3025
3026 2002-10-13 Akim Demaille <akim@epita.fr>
3027
3028 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
3029 (O0FLAGS): New.
3030 (VALGRIND, GXX): New.
3031 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
3032 * tests/bison.in: Run $PREBISON a pre-command.
3033 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
3034 (maintainer-check-g++): New.
3035 * Makefile.am (maintainer-check): New.
3036
3037 2002-10-13 Akim Demaille <akim@epita.fr>
3038
3039 * data/glr.c: Formatting changes.
3040 Tweak some trace messages to match yacc.c's.
3041
3042 2002-10-13 Akim Demaille <akim@epita.fr>
3043
3044 GLR parsers sometimes raise parse errors instead of performing the
3045 default reduction.
3046 Reported by Charles-Henry de Boysson.
3047
3048 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
3049 check the length of the traces when %glr.
3050 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
3051 GLR's traces.
3052 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
3053 Test GLR parsers.
3054 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
3055 (yyltype): Remove the yy prefix from the member names.
3056 (yytable): Complete its comment.
3057 (yygetLRActions): Map error action number from YYTABLE from
3058 YYTABLE_NINF to 0.
3059 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
3060 (which was a bug: it should have been YYTABEL_NINF, and yet it was
3061 not satisfying as we could compare an YYACTION computed from
3062 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
3063 only value for error actions.
3064 (yyreportParseError): In verbose parse error messages, don't issue
3065 `error' in the list of expected tokens.
3066 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
3067 next action to perform to match glr.c's decoding.
3068 (yytable): Complete its comment.
3069
3070 2002-10-13 Paul Eggert <eggert@twinsun.com>
3071
3072 Fix problem reported by Henrik Grubbstroem in
3073 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
3074 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
3075 because the Bison parser reads the second action before reducing
3076 the first one.
3077 * src/scan-gram.l (rule_length): New static var.
3078 Use it to keep track of the rule length in the scanner, since
3079 we can't expect the parser to be in lock-step sync with the scanner.
3080 (handle_action_dollar, handle_action_at): Use this var.
3081 * tests/actions.at (Exotic Dollars): Test for the problem.
3082
3083 2002-10-12 Paul Eggert <eggert@twinsun.com>
3084
3085 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
3086 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
3087 Include <sys/time.h> when checking for clock_t and struct tms.
3088 Use same include order as source.
3089 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
3090 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
3091
3092 * lib/timevar.c: Update copyright date and clarify comments.
3093 (get_time) [IN_GCC]: Keep the GCC version for reference.
3094
3095 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
3096 GCC version as of today, then merge Bison's changes.
3097 Change "GCC" to "Bison" in copyright notice. timevar.def's
3098 author is Akim, so change that too.
3099
3100 * src/reader.c (grammar_current_rule_check):
3101 Don't worry about the default action if $$ is untyped.
3102 Prevents bogus warnings reported by Jim Gifford in
3103 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
3104
3105 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
3106 * data/glr.c, data/lalr1.cc, data/yacc.c:
3107 Output token definitions before the first part of user declarations.
3108 Fixes compatibility problem reported by Jim Gifford for kbd in
3109 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
3110
3111 2002-10-11 Paul Eggert <eggert@twinsun.com>
3112
3113 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
3114 (yyparse): here. This undoes some of the 2002-07-25 change.
3115 Compatibility problem reported by Ralf S. Engelschall with
3116 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
3117
3118 2002-10-11 Akim Demaille <akim@epita.fr>
3119
3120 * tests/regression.at Characters Escapes): New.
3121 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
3122 characters.
3123 Reported by Jan Nieuwenhuizen.
3124
3125 2002-10-11 Akim Demaille <akim@epita.fr>

3127 * po/id.po: New.
3128
3129 2002-10-10 Paul Eggert <eggert@twinsun.com>
3130
3131 Portability fixes for bitsets; this also avoids several GCC
3132 warnings.
3133
3134 * lib/abitset.c: Include <stddef.h>, for offsetof.
3135 * lib/lbitset.c: Likewise.
3136
3137 * lib/abitset.c (abitset_bytes): Return a size that is aligned
3138 properly for vectors of objects. Do not assume that adding a
3139 header size to a multiple of a word size yields a value that is
3140 properly aligned for the whole union.
3141 * lib/bitsetv.c (bitsetv_alloc): Likewise.
3142
3143 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
3144 unique names for structures.
3145 * lib/ebitset.c (ebitset_bytes): Likewise.
3146 * lib/lbitset.c (lbitset_bytes): Likewise.
3147
3148 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
3149 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
3150 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
3151 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
3152 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
3153 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
3154 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
3155 to improve the type-checking that GCC can do.
3156 * lib/bitset.c (bitset_op4_cmp): Likewise.
3157 * lib/bitset_stats.c (bitset_stats_count,
3158 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
3159 bitset_stats_copy, bitset_stats_disjoint_p,
3160 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
3161 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
3162 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
3163 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
3164 bitset_stats_and_or_cmp, bitset_stats_andn_or,
3165 bitset_stats_andn_or_cmp, bitset_stats_or_and,
3166 bitset_stats_or_and_cmp): Likewise.
3167 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
3168 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
3169 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
3170 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
3171
3172 * lib/abitset.h: Include bitset.h, not bbitset.h.
3173 * lib/ebitset.h: Likewise.
3174 * lib/lbitset.h: Likewise.
3175
3176 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
3177 All instances of parameters of type enum bitset_opts are now of
3178 type enum_bitset_opts, to conform to the C Standard, and similarly
3179 for enum_bitset_type.
3180 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
3181 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
3182
3183 Do not use "struct bitset_struct" to mean different things in
3184 different modules. Not only is this confusing, it violates
3185 the C Standard, which requires that structure types in different
3186 modules must be compatible if one is to be passed to the other.
3187 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
3188 All instances of "struct bitset_struct *" replaced with "bitset".
3189 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
3190 (union bitset_union, struct abitset_struct, struct ebitset_struct,
3191 struct lbitset_struct, struct bitset_stats_struct): New types.
3192 All uses of struct bitset_struct changed to union bitset_union,
3193 etc.
3194 * lib/abitset.c (struct abitset_struct, abitset,
3195 struct bitset_struct): Remove.
3196 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
3197 struct bitset_struct): Remove.
3198 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
3199 bitset_struct): Remove.
3200 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
3201 Likewise.
3202
3203 Do not call a function of type T using a call that assumes the
3204 function is of a different type U. Standard C requires that a
3205 function must be called with a type that is compatible with its
3206 definition.
3207 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
3208 New decls.
3209 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
3210 New functions.
3211 * lib/ebitset.c (PFV): Remove.
3212 * lib/lbitset.c (PFV): Likewise.
3213 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
3214 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
3215 decls.
3216 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
3217 (ebitset_vtable): Use them.
3218 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
3219 lbitset_xor): New functions.
3220 (lbitset_vtable): Use them.
3221
3222 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
3223 Declare.
3224
3225 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
3226 GCC warning.
3227 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
3228 Use offsetof, for simplicity.
3229
3230 2002-10-06 Paul Eggert <eggert@twinsun.com>
3231
3232 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
3233 the same width as int. This reapplies a hunk of the 2002-08-12 patch
3234 <http://mail.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
3235 which was inadvertently undone by the 2002-09-30 patch.
3236 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
3237 the same width as int.
3238
3239 2002-10-04 Paul Eggert <eggert@twinsun.com>
3240
3241 Version 1.50.

3243 * configure.ac (AC_INIT), NEWS: Increment version number.
3244
3245 * doc/bison.texinfo: Minor spelling, grammar, and white space
3246 fixes.
3247 (Symbols): Mention that any negative value returned from yylex
3248 signifies end-of-input. Warn about negative chars. Mention
3249 the portable Standard C character set.
3250
3251 The GNU coding standard says CFLAGS and YFLAGS are reserved
3252 for the installer to set.
3253 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
3254 * src/Makefile.am (AM_CFLAGS): Likewise.
3255 (AM_YFLAGS): Renamed from YFLAGS.
3256
3257 Fix some MAX and MIN problems.
3258 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
3259 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
3260 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
3261 * src/reader.c (reader): Use it.
3262
3263 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
3264 POSIX 1003.1-2001 has removed fgrep.
3265
3266 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
3267
3268 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
3269 interpreted as signed.
3270 * lib/ebitset.c (ebitset_list): Fix bug.
3271
3272 2002-10-01 Paul Eggert <eggert@twinsun.com>
3273
3274 More fixes for 64-bit hosts and large bitsets.
3275
3276 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
3277 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
3278 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
3279 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
3280 struct bitset_vtable.list, struct bitset_vtable.list_reverse,
3281 bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,

3297 Likewise.
3298
3299 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
3300 Use size_t, not unsigned int, to count bytes.
3301 * lib/abitset.h (abitset_bytes): Likewise.
3302 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):

3338 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
3339 to BITSET_WINDEX_MAX.
3340
3341 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
3342 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
3343 since we now return the bitset_bindex type (not int).

3442
3443 * doc/bison.texinfo (Conditions): Make explicit that the GPL
3444 exception applies only to yacc.c. This is a modification of a
3445 patch originally suggested by Akim Demaille.
3446
3447 2002-09-06 Akim Demaille <akim@epita.fr>
3448

3456
3457 2002-09-04 Jim Meyering <jim@meyering.net>
3458
3459 * data/yacc.c: Guard the declaration of yytoknum also with
3460 `#ifdef YYPRINT', so it is declared only when used.
3461
3462 2002-09-04 Akim Demaille <akim@epita.fr>
3463
3464 * configure.in: Rename as...

3494 functions are not portable. Do not assume size_t is the
3495 same width as int.
3496 (yypstates): Do not assume that ptrdiff_t is the same width
3497 as int, and similarly for yyposn and YYINDEX.
3498
3499 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
3500
3501 * lib/Makefile.am (INCLUDES): Do not include from the intl
3502 directory, which has been removed.
3503 * src/Makefile.am (INCLUDES): Likewise.

3536 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
3537
3538 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
3539 PROTOTYPES to check for prototypes, and "defined __STDC__" to
3540 check for void *.
3541
3542 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
3543 size_t; the old version tried to do this but casted improperly.
3544 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
3545 (bitset_test): Now returns int, not unsigned long.
3546
3547 * lib/bitset_stats.c: Include "gettext.h".
3548 (_): New macro.
3549 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
3550 name locals "index", as it generates unnecessary warnings on some
3551 hosts that have an "index" function.

3554 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

3575 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
3576 lib/timevar.c.
3577 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
3578 manual recommends.
3579 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
3580
3581 * src/complain.c (strerror_r): Remove decl; not needed.
3582 (strerror): Use same pattern as ../lib/error.c.
3583
3584 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
3585
3586 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
3587
3588 * src/main.c (main): Cast result of bindtextdomain and textdomain
3589 to void, to avoid a GCC warning when --disable-nls is in effect.
3590
3591 * src/scan-gram.l: Use strings rather than escapes when possible,
3592 to minimize the number of warnings from xgettext.
3593 (handle_action_dollar, handle_action_at): Don't use isdigit,
3594 as it mishandles negative chars and it may not work as expected
3595 outside the C locale.
3596
3597 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
3598 this is a GCC extension and is not portable to other compilers.
3599
3600 * src/system.h (alloca): Use same pattern as ../lib/error.c.
3601 Do not include <ctype.h>; no longer needed.
3602 Do not include <malloc.h>; no longer needed (and generates
3603 warnings on OpenBSD 3.0).
3604
3605 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
3606 it's not portable.
3607
3608 * tests/regression.at: Do not use 'cc -c input.c -o input';

3610
3611 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
3612 exit status as failure, not just exit status 1. Sun C exits
3613 with status 2 sometimes.
3614
3615 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
3616 Use it for the two large tests.
3617
3618 2002-08-02 Akim Demaille <akim@epita.fr>
3619
3620 * src/conflicts.c (conflicts_output): Don't output rules never

3629 reduced to...

3632 that rules never reduced are computed.
3633 Call grammar_rules_never_reduced_report.
3634 * src/print.c (print_results): Report rules never reduced.
3635 * tests/conflicts.at, tests/reduce.at: Adjust.
3636
3637 2002-08-01 Akim Demaille <akim@epita.fr>
3638
3639 Instead of attaching lookaheads and duplicating the rules being
3640 reduced by a state, attach the lookaheads to the reductions.
3641
3642 * src/state.h (state_t): Remove the `lookaheads',
3643 `lookaheads_rule' member.
3644 (reductions_t): Add a `lookaheads' member.
3645 Use a regular array for the `rules'.

3656 (initialize_LA): this.
3657 (lalr_free): Adjust.
3658 * src/main.c (main): Don't free nullable and derives too early: it
3659 is used by --verbose.
3660 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
3661
3662 2002-08-01 Akim Demaille <akim@epita.fr>

3668 Adjust all dependencies.
3669 * src/nullable.c (set_nullable, free_nullable): Rename as...
3670 (nullable_compute, nullable_free): these.
3671 (rule_list_t): Store rule_t *, not rule_number_t.
3672 * src/state.c (state_rule_lookaheads_print): Directly compare rule
3673 pointers, instead of their numbers.
3674 * src/main.c (main): Call nullable_free, and derives_free earlier,
3675 as they were lo longer used.
3676
3677 2002-08-01 Akim Demaille <akim@epita.fr>
3678
3679 * lib/timevar.c (get_time): Include children time.

3685 * src/tables.c (pack_vector): Check whether loc is >= to the
3686 table_size, not >.
3687 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
3688 (tables_generate): do it, since that's also it which allocates
3689 them.
3690 Don't free LA and LArule, main does.
3691
3692 2002-07-31 Akim Demaille <akim@epita.fr>

3753
3754 2002-07-30 Akim Demaille <akim@epita.fr>
3755

3777 by conflicts.
3778
3779 * src/LR0.c (save_reductions): Don't make the final state too
3780 different: save its reduction (accept) instead of having a state
3781 without any action (no shift or goto, no reduce).
3782 Note: the final state is now a ``regular'' state, i.e., the
3783 parsers now contain `reduce 0' as default reduction.
3784 Nevertheless, since they decide to `accept' when yystate =
3785 final_state, they still will not reduce rule 0.
3786 * src/print.c (print_actions, print_reduction): Adjust.

3828 2002-07-26 Akim Demaille <akim@epita.fr>
3829
3830 * src/reader.h, src/reader.c (gram_error): ... can't get
3831 yycontrol without making too strong assumptions on the parser
3832 itself.
3833 * src/output.c (prepare_tokens): Use the real 0th value of
3834 token_translations instead of `0'.
3835 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
3836 visible here.
3837 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
3838 for the time being: %locations ought to provide it to yyerror.

3851 * src/nullable.c, src/output.c, src/print.c, src/reader.c
3852 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
3853 Iterate from 0 to nrules.
3854 Use rule_number_as_item_number and item_number_as_rule_number.
3855 Adjust to `derive' now containing possibly 0.
3856 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
3857 Handle the `- 1' part in rule numbers from/to item numbers.

5507 (item_number_as_token_number): New.
5508 * src/output.c (GENERATE_OUTPUT_TABLE): New.
5509 Use it to create output_item_number_table and
5510 output_token_number_table.
5511 * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,
5512 * src/lex.c, src/nullable.c, src/output.c, src/print.c,
5513 * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,
5514 * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.

5516 2002-04-22 Akim Demaille <akim@epita.fr>
5517
5518 * src/output.h, src/output.c (get_lines_number): Remove.
5519
5520 2002-04-19 Akim Demaille <akim@epita.fr>
5521
5522 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
5523 as Lex/Flex'.
5524 (Debugging): More details about enabling the debugging features.
5525 (Table of Symbols): Describe $$, $n, @$, and @n.
5526 Suggested by Tim Josling.
5527
5528 2002-04-19 Akim Demaille <akim@epita.fr>
5529
5530 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
5531
5532 2002-04-10 Akim Demaille <akim@epita.fr>
5533
5534 * src/system.h: Rely on HAVE_LIMITS_H.
5535 Suggested by Paul Eggert.
5536
5537 2002-04-09 Akim Demaille <akim@epita.fr>
5538
5539 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
5540 full stderr, and strip it according to the bison options, instead
5541 of composing the error message from different bits.
5542 This makes it easier to check for several error messages.
5543 Adjust all the invocations.
5544 Add an invocation exercising the error token.
5545 Add an invocation demonstrating a stupid error message.
5546 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
5547 Adjust the tests.
5548 Error message are for stderr, not stdout.
5549
5550 2002-04-09 Akim Demaille <akim@epita.fr>
5551
5552 * src/gram.h, src/gram.c (error_token_number): Remove, use
5553 errtoken->number.
5554 * src/reader.c (reader): Don't specify the user token number (2)
5555 for $undefined, as it uselessly prevents using it.
5556 * src/gram.h (token_number_t): Move to...
5557 * src/symtab.h: here.
5558 (state_t.number): Is a token_number_t.
5559 * src/print.c, src/reader.c: Use undeftoken->number instead of
5560 hard coded 2.
5561 (Even though this 2 is not the same as above: the number of the
5562 undeftoken remains being 2, it is its user token number which
5563 might not be 2).
5564 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
5565 `user_token_number_max'.
5566 Output `undef_token_number'.
5567 * data/bison.simple, data/bison.c++: Use them.
5568 Be sure to map invalid yylex return values to
5569 `undef_token_number'. This saves us from gratuitous SEGV.
5570
5571 * tests/conflicts.at (Solved SR Conflicts)
5572 (Unresolved SR Conflicts): Adjust.
5573 * tests/regression.at (Web2c Actions): Adjust.
5574

5581 Use __ofile__.
5582 * data/bison.simple: Use __ofile__.
5583 * src/scan-skel.l: Handle __ofile__.

5586
5587 * src/gram.h (item_number_t): New, the type of item numbers in
5588 RITEM. Note that it must be able to code symbol numbers as
5589 positive number, and the negation of rule numbers as negative
5590 numbers.
5591 Adjust all dependencies (pretty many).
5592 * src/reduce.c (rule): Remove this `short *' pointer: use
5593 item_number_t.
5594 * src/system.h (MINSHORT, MAXSHORT): Remove.
5595 Include `limits.h'.
5596 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
5597 (shortcpy): Remove.

5603 500.
5604 * tests/regression.at (Web2c Actions): Ajust.
5605
5606 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
5607 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
5608 passes, but produces negative #line number, once fixed, GCC is
5609 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
5610 C), it passes.
5611 * src/state.h (state_h): Code input lines on ints, not shorts.
5612
5613 2002-04-08 Akim Demaille <akim@epita.fr>
5614
5615 * src/reduce.c (reduce_grammar): First reduce the nonterminals,
5616 and then the grammar.

5628 New.
5629 Use them to define yy_token_number_type/TokenNumberType.
5630 Use this type for yytranslate.
5631 * tests/torture.at (Big triangle): Push the limit from 124 to
5632 253.
5633 * tests/regression.at (Web2c Actions): Adjust.

5640
5641 2002-04-07 Akim Demaille <akim@epita.fr>

5709

5738
5739 2002-04-07 Akim Demaille <akim@epita.fr>

5759
5760 * src/LR0.c (new_state): Display `nstates' as the name of the
5761 newly created state.
5762 Adjust to initialize first_state and last_state if needed.
5763 Be sure to distinguish the initial from the final state.

5765 new_state.
5766 * src/closure.c (closure): Now that the initial state has its
5767 items properly set, there is no need for a special case when
5768 creating `ruleset'.
5769
5770 As a result, now the rule 0, reducing to $axiom, is visible in the

5809 2002-04-07 Akim Demaille <akim@epita.fr>
5810

5812 lacking `+ 1' to nrules, Bison reported as useless a token if it
5813 was used solely to set the precedence of the last rule...
5814
5815 2002-04-07 Akim Demaille <akim@epita.fr>
5816
5817 * data/bison.c++, data/bison.simple: Don't output the current file
5818 name in #line, to avoid useless diffs between two identical

5822
5823 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

5840 RHS, instead of being an index in RITEMS.

6108
6109 2002-02-14 Paul Eggert <eggert@twinsun.com>
6110
6111 Remove the support for C++ namespace cleanliness; it was
6112 causing more problems than it was curing, since it didn't work
6113 properly on some nonstandard C++ compilers. This can wait
6114 for a proper C++ parser.
6115
6116 * NEWS: Document this.
6117 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
6118 of C++, as it's treated like C now.

6160 directives around tables only needed for debugging.
6161
6162 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
6163
6164 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
6165 C++ parsers.
6166 (yy::b4_name::parse): Use print_.
6167
6168 2002-02-07 Robert Anisko <robert@lrde.epita.fr>

6198 BISON_HAIRY.
6199 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS

6207 action member.
6208 Adjust callers.
6209 (output_skeleton): Don't look for the skeleton location, let m4 do
6210 that.
6211 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
6212 file will be used.
6213 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
6214 (prepare): Given that for the time being changesyntax is not
6215 usable in M4, rename the muscles using `-' to `_'.

6217 * src/output.h (actions_output, guards_output)
6218 (token_definitions_output): Adjust prototypes.
6219 * src/scan-skel.l: Instead of scanning the skeletons, it now
6220 processes the output of m4: `__oline__' and `#output'.

6222 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
6223 to date.
6224 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
6225 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
6226 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
6227 shamelessly stolen from CVS Autoconf.

6246
6247 * src/bison.simple (YYSIZE_T): Do not define merely because
6248 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

6251 2002-01-27 Akim Demaille <akim@epita.fr>
6252
6253 Fix `%nonassoc and eof'.
6254
6255 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
6256 which were not properly copied! Replace
6257 memcpy (res->errs, src->errs, src->nerrs);
6258 with
6259 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
6260 !!!
6261 * tests/regression.at (%nonassoc and eof): Adjust to newest
6262 Autotest: `.' is not in the PATH.
6263

6321 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
6322
6323 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
6324 canonical definition.
6325 * src/system.h: Use the canonical definition for PARAMS (avoids

6395 2002-01-06 Akim Demaille <akim@epita.fr>
6396
6397 Creating package.m4 from configure.ac causes too many problems.
6398
6399 * tests/Makefile.am (package.m4): Create it by hand,
6400 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
6401
6402 2002-01-06 Akim Demaille <akim@epita.fr>
6403
6404 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
6405 skeleton.h.
6406
6407 2002-01-04 Paul Eggert <eggert@twinsun.com>
6408
6409 * doc/bison.texinfo (Debugging):
6410 Remove YYSTDERR; it's no longer defined or used.
6411 Also, s/cstdio.h/cstdio/.
6412
6413 2002-01-03 Akim Demaille <akim@epita.fr>
6414
6415 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
6416
6417 2002-01-03 Akim Demaille <akim@epita.fr>
6418
6419 * src/parse-skel.y (process_skeleton): Don't bind the parser's
6420 tracing code to --trace, wait for a better --trace option, with
6421 args.
6422
6423 2002-01-03 Akim Demaille <akim@epita.fr>
6424
6425 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
6426 The ISO C++ standard is extremely clear about it: stderr is
6427 considered a macro, not a regular symbol (see table 94 `Header
6428 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
6429 Therefore std:: does not apply to it. It still does with fprintf.
6430 Also, s/cstdio.h/cstdio/.
6431
6432 2002-01-03 Akim Demaille <akim@epita.fr>
6433
6434 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
6435 for non system headers.
6436
6437 2002-01-02 Akim Demaille <akim@epita.fr>
6438
6439 Equip the skeleton chain with location tracking, runtime trace,
6440 pure parser and scanner.
6441
6442 * src/parse-skel.y: Request a pure parser, locations, and prefix
6443 renaming.
6444 (%union): Having several members with the same type does not help
6445 type mismatches, simplify.
6446 (YYPRINT, yyprint): New.
6447 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
6448 (skel_error): this.
6449 Handle locations.
6450 * src/scan-skel.l: Adjust to these changes.
6451 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
6452 (LOCATION_PRINT, skel_control_t): New.
6453
6454 2001-12-30 Akim Demaille <akim@epita.fr>
6455
6456 * src/parse-skel.y: Get rid of the shift/reduce conflict:
6457 replace `gb' with BLANKS.
6458 * src/scan-skel.l: Adjust.
6459
6460 2001-12-30 Akim Demaille <akim@epita.fr>
6461
6462 * src/system.h: We don't need nor want bcopy.
6463 Throw away MS-DOS crap: we don't need getpid.
6464 * configure.in: We don't need strndup. It was even causing
6465 problems: because Flex includes the headers *before* us,
6466 _GNU_SOURCE is not defined by config.h, and therefore strndup was
6467 not visible.
6468 * lib/xstrndup.c: New.
6469 * src/scan-skel.l: Use it.
6470 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
6471 * src/parse-skel.y: Use %directives instead of #defines.
6472
6473 2001-12-30 Akim Demaille <akim@epita.fr>
6474
6475 * src/skeleton.h: New.
6476 * src/output.c (output_parser, output_master_parser): Remove, dead
6477 code.
6478 * src/output.h (get_lines_number, actions_output, guards_output)
6479 (token_definitions_output): Prototype them.
6480 * src/parse-skel.y: Add the license notice.
6481 Include output.h and skeleton.h.
6482 (process_skeleton): Returns void, and takes a single parameter.
6483 * src/scan-skel.l: Add the license notice.
6484 Include skeleton.h.
6485 Don't use %option yylineno: it seems that then Flex imagines
6486 REJECT has been used, and therefore it won't reallocate its
6487 buffers (which makes no other sense to me than a bug). It results
6488 in warnings for `unused: yy_flex_realloc'.
6489
6490 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
6491
6492 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
6493 (MUSCLE_INSERT_PREFIX): ...to there.
6494 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
6495 (MUSCLE_INSERT_PREFIX): Move from here...
6496
6497 * src/bison.hairy: Add a section directive. Put braces around muscle
6498 names. This parser skeleton is still broken, but Bison should not
6499 choke on a bad muscle 'syntax'.
6500 * src/bison.simple: Add a section directive. Put braces around muscle
6501 names.
6502
6503 * src/files.h (strsuffix, stringappend): Add declarations.
6504 (tab_extension): Add declaration.
6505 (short_base_name): Add declaration.
6506
6507 * src/files.c (strsuffix, stringappend): No longer static. These
6508 functions are used in the skeleton parser.
6509 (tab_extension): New.
6510 (compute_base_names): Use the computations done in this function
6511 to guess if the generated parsers should have '.tab' in their
6512 names.
6513 (short_base_name): No longer static.
6514
6515 * src/output.c (output_skeleton): New.
6516 (output): Disable call to output_master_parser, and give a try to
6517 a new skeleton handling system.
6518 (guards_output, actions_output): No longer static.
6519 (token_definitions_output, get_lines_number): No longer static.
6520
6521 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
6522
6523 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
6524 parse-skel.y.
6525
6526 * src/parse-skel.y: New file.
6527 * src/scan-skel.l: New file.
6528
6529 2001-12-29 Akim Demaille <akim@epita.fr>
6530
6531 %name-prefix is broken.
6532
6533 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
6534 Adjust all dependencies.
6535 * tests/headers.at (export YYLTYPE): Strengthen this test: use
6536 %name-prefix.
6537
6538 Renaming yylval but not yylloc is not consistent. Now we do.
6539
6540 * src/bison.simple: Prefix yylloc if used.
6541 * doc/bison.texinfo (Decl Summary): Document that.
6542
6543 2001-12-29 Akim Demaille <akim@epita.fr>
6544
6545 * doc/bison.texinfo: Promote `%long-directive' over
6546 `%long_directive'.
6547 Remove all references to fixed-output-files, yacc is enough.
6548
6549 2001-12-29 Akim Demaille <akim@epita.fr>
6550
6551 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
6552 user prologue. These are defaults.
6553 * tests/actions.at (Mid-rule actions): Make sure the user can
6554 define YYDEBUG and YYERROR_VERBOSE.
6555
6556 2001-12-29 Akim Demaille <akim@epita.fr>
6557
6558 * src/output.c (header_output): Don't forget to export YYLTYPE and
6559 yylloc.
6560 * tests/headers.at (export YYLTYPE): New, make sure it does.
6561 * tests/regression.at (%union and --defines, Invalid CPP headers):
6562 Move to...
6563 * tests/headers.at: here.
6564
6565 2001-12-29 Akim Demaille <akim@epita.fr>
6566
6567 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
6568
6569 2001-12-29 Akim Demaille <akim@epita.fr>
6570
6571 * tests/actions.at (Mid-rule actions): Output on a single line
6572 instead of several.
6573
6574 2001-12-29 Akim Demaille <akim@epita.fr>
6575
6576 * doc/bison.texinfo: Formatting changes.
6577
6578 2001-12-29 Akim Demaille <akim@epita.fr>
6579
6580 Don't store the token defs in a muscle, just be ready to output it
6581 on command. Now possible via `symbols'. Fixes a memory leak.
6582
6583 * src/output.c (token_definitions_output): New.
6584 (output_parser, header_output): Use it.
6585 * src/reader.c (symbols_save): Remove.
6586
6587 2001-12-29 Akim Demaille <akim@epita.fr>
6588
6589 * src/bison.simple: Do not provide a default for YYSTYPE and
6590 YYLTYPE before the user's prologue. Otherwise it's hardly... a
6591 default.
6592
6593 2001-12-29 Akim Demaille <akim@epita.fr>
6594
6595 Mid-rule actions are simply... ignored!
6596
6597 * src/reader.c (readgram): Be sure to attach mid-rule actions to
6598 the empty-rule associated to the dummy symbol, not to the host
6599 rule.
6600 * tests/actions.at (Mid-rule actions): New.
6601
6602 2001-12-29 Akim Demaille <akim@epita.fr>
6603
6604 Memory leak.
6605
6606 * src/reader.c (reader): Free grammar.
6607
6608 2001-12-29 Akim Demaille <akim@epita.fr>
6609
6610 Memory leak.
6611
6612 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
6613 since it allocates it for each state, although only one is needed.
6614 (allocate_storage): Do it here.
6615
6616 2001-12-29 Akim Demaille <akim@epita.fr>
6617
6618 * src/options.h, src/options.c (create_long_option_table): Rename
6619 as...
6620 (long_option_table_new): this, with a clearer prototype.
6621 (percent_table): Remove, unused,
6622 * src/getargs.c (getargs): Adjust.
6623
6624 2001-12-29 Akim Demaille <akim@epita.fr>
6625
6626 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
6627 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
6628 as states.
6629
6630 2001-12-29 Akim Demaille <akim@epita.fr>
6631
6632 * src/lalr.c (build_relations): Rename `states' as `states1'.
6633 Sorry, I don't understand exactly what it is, no better name...
6634
6635 2001-12-29 Akim Demaille <akim@epita.fr>
6636
6637 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
6638 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
6639 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
6640 as rules.
6641
6642 2001-12-29 Akim Demaille <akim@epita.fr>
6643
6644 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
6645 ago.
6646
6647 2001-12-29 Akim Demaille <akim@epita.fr>
6648
6649 * src/reader.c, src/reader.h (user_toknums): Remove.
6650 Adjust all users to use symbols[i]->user_token_number.
6651
6652 2001-12-29 Akim Demaille <akim@epita.fr>
6653
6654 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
6655 Adjust all users to use symbols[i]->prec or ->assoc.
6656
6657 2001-12-29 Akim Demaille <akim@epita.fr>
6658
6659 * src/reader.c, src/reader.h (tags): Remove.
6660 Adjust all users to use symbols[i]->tag.
6661
6662 2001-12-29 Akim Demaille <akim@epita.fr>
6663
6664 * src/gram.h, src/gram.c (symbols): New, similar to state_table
6665 and rule_table.
6666 * src/reader.c (packsymbols): Fill this table.
6667 Drop sprec.
6668 * src/conflicts.c (resolve_sr_conflict): Adjust.
6669 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
6670 single table.
6671 Use symbols[i]->tag instead of tags[i].
6672
6673 2001-12-29 Akim Demaille <akim@epita.fr>
6674
6675 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
6676 In addition, put a comment in there, to replace...
6677 * tests/regression.at (%union and C comments): Remove.
6678
6679 2001-12-29 Akim Demaille <akim@epita.fr>
6680
6681 * tests/regression.at (Web2c Actions): Blindly move the actual
6682 output as expected output. The contents *seem* right to me, but I
6683 can't pretend reading perfectly parser tables... Nonetheless, all
6684 the other tests pass correctly, the table look OK, even though the
6685 presence of `$axiom' is to be noted: AFAICS it is useless (but
6686 harmless).
6687
6688 2001-12-29 Akim Demaille <akim@epita.fr>
6689
6690 * src/reader.c (readgram): Don't add the rule 0 if there were no
6691 rules read. In other words, add it _after_ having performed
6692 grammar sanity checks.
6693 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
6694
6695 2001-12-29 Akim Demaille <akim@epita.fr>
6696
6697 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
6698 visible, and some states have now a different number.
6699
6700 2001-12-29 Akim Demaille <akim@epita.fr>
6701
6702 * src/reader.c (readgram): Bind the initial rule's lineno to that
6703 of the first rule.
6704 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
6705 (Solved SR Conflicts): Adjust rule 0's line number.
6706
6707 2001-12-29 Akim Demaille <akim@epita.fr>
6708
6709 Fix the `GAWK Grammar' failure.
6710
6711 * src/LR0.c (final_state): Initialize to -1 so that we do compute
6712 the reductions of the first state which was mistakenly confused
6713 with the final state because precisely final_state was initialized
6714 to 0.
6715 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
6716 now noticed by Bison.
6717 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
6718 have a reduction on $default.
6719
6720 2001-12-29 Akim Demaille <akim@epita.fr>
6721
6722 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
6723 rule line numbers.
6724 * src/closure.c (print_closure): Likewise.
6725 * src/derives.c (print_derives): Likewise.
6726 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
6727 now.
6728
6729 2001-12-29 Akim Demaille <akim@epita.fr>
6730
6731 * src/lalr.c (lookaheads_print): New.
6732 (lalr): Call it when --trace-flag.
6733 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
6734 are dumped.
6735
6736 2001-12-29 Akim Demaille <akim@epita.fr>
6737
6738 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
6739 when walking through ritem, even via rule->rhs.
6740 * src/reduce.c (dump_grammar, useful_production, reduce_output)
6741 (useful_production, useless_nonterminals): Likewise.
6742 (reduce_grammar_tables): Likewise, plus update nritems.
6743 * src/nullable.c (set_nullable): Likewise.
6744 * src/lalr.c (build_relations): Likewise.
6745 * tests/sets.at (Nullable): Adjust.
6746 Fortunately, now, the $axiom is no longer nullable.
6747
6748 2001-12-29 Akim Demaille <akim@epita.fr>
6749
6750 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
6751 the 0-sentinel.
6752 * src/gram.c (ritem_longest_rhs): Likewise.
6753 * src/reduce.c (nonterminals_reduce): Likewise.
6754 * src/print_graph.c (print_graph): Likewise.
6755 * src/output.c (output_rule_data): Likewise.
6756 * src/nullable.c (set_nullable): Likewise.
6757
6758 2001-12-29 Akim Demaille <akim@epita.fr>
6759
6760 * src/output.c: Comment changes.
6761
6762 2001-12-27 Paul Eggert <eggert@twinsun.com>
6763
6764 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
6765 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
6766 Sparc, as they were causing more porting problems than the
6767 (minor) performance improvement was worth.
6768
6769 Also, catch up with 1.31's YYSTD.
6770
6771 2001-12-27 Akim Demaille <akim@epita.fr>
6772
6773 * src/output.c (output_gram): Rely on nritems, not the
6774 0-sentinel. See below.
6775 Use -1 as separator, not 0.
6776 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
6777 Rely on -1 as separator in yyrhs, instead of 0.
6778 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
6779 twice `Now at end of input', therefore there are two lines less to
6780 expect.
6781
6782 2001-12-27 Akim Demaille <akim@epita.fr>
6783
6784 * tests/regression.at (Unresolved SR Conflicts):
6785 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
6786 below.
6787
6788 2001-12-27 Akim Demaille <akim@epita.fr>
6789
6790 * src/LR0.c (new_state): Recognize the final state by the fact it
6791 is reached by eoftoken.
6792 (insert_start_shifting_state, insert_eof_shifting_state)
6793 (insert_accepting_state, augment_automaton): Remove, since now
6794 these states are automatically computed from the initial state.
6795 (generate_states): Adjust.
6796 * src/print.c: When reporting a rule number to the user, substract
6797 1, so that the axiom rule is rule 0, and the first user rule is 1.
6798 * src/reduce.c: Likewise.
6799 * src/print_graph.c (print_core): For the time being, just as for
6800 the report, depend upon --trace-flags to dump the full set of
6801 items.
6802 * src/reader.c (readgram): Once the grammar read, insert the rule
6803 0: `$axiom: START-SYMBOL $'.
6804 * tests/set.at: Adjust: rule 0 is now displayed, and since the
6805 number of the states has changed (the final state is no longer
6806 necessarily the last), catch up.
6807
6808 2001-12-27 Akim Demaille <akim@epita.fr>
6809
6810 Try to make the use of the eoftoken valid. Given that its value
6811 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
6812 is used instead of > 0 where appropriate, (ii), depend upon nritems
6813 instead of the 0-sentinel.
6814
6815 * src/gram.h, src/gram.c (nritems): New.
6816 Expected to be duplication of nitems, but for the time being...
6817 * src/reader.c (packgram): Assert nritems and nitems are equal.
6818 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
6819 * src/closure.c (print_closure, print_fderives): Likewise.
6820 * src/gram.c (ritem_print): Likewise.
6821 * src/print.c (print_core, print_grammar): Likewise.
6822 * src/print_graph.c: Likewise.
6823
6824 2001-12-27 Akim Demaille <akim@epita.fr>
6825
6826 * src/main.c (main): If there are complains after grammar
6827 reductions, then output the report anyway if requested, then die.
6828 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
6829 * src/reader.c (eoftoken): New.
6830 (parse_token_decl): If the token being defined has value `0', it
6831 is the eoftoken.
6832 (packsymbols): No longer hack `tags' to insert `$' by hand.
6833 Be sure to preserve the value of the eoftoken.
6834 (reader): Make sure eoftoken is defined.
6835 Initialize nsyms to 0: now eoftoken is created just like the others.
6836 * src/print.c (print_grammar): Don't special case the eof token.
6837 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
6838 lie anyway, albeit pleasant.
6839 * tests/calc.at: Exercise error messages with eoftoken.
6840 Change the grammar so that empty input is invalid.
6841 Adjust expectations.
6842 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
6843
6844 2001-12-27 Akim Demaille <akim@epita.fr>
6845
6846 * configure.in: Check the protos of strchr ans strspn.
6847 Replace strchr if needed.
6848 * src/system.h: Provide the protos of strchr, strspn and memchr if
6849 missing.
6850 * lib/strchr.c: New.
6851 * src/reader.c (symbols_save): Use strchr.
6852
6853 2001-12-27 Akim Demaille <akim@epita.fr>
6854
6855 * src/print.c, src/print_graph.c (escape): New.
6856 Use it to quote the TAGS outputs.
6857 * src/print_graph.c (print_state): Now errors are in red, and
6858 reductions in green.
6859 Prefer high to wide: output the state number on a line of its own.
6860
6861 2001-12-27 Akim Demaille <akim@epita.fr>
6862
6863 * src/state.h, src/state.c (reductions_new): New.
6864 * src/LR0.c (set_state_table): Let all the states have a
6865 `reductions', even if reduced to 0.
6866 (save_reductions): Adjust.
6867 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
6868 * src/print.c (print_reductions, print_actions): Adjust.
6869 * src/output.c (action_row): Adjust.
6870
6871 2001-12-27 Akim Demaille <akim@epita.fr>
6872
6873 * src/state.h, src/state.c (errs_new, errs_dup): New.

6880 2001-12-27 Akim Demaille <akim@epita.fr>
6881
6882 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
6883
6884 2001-12-27 Akim Demaille <akim@epita.fr>
6885
6886 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
6887 * src/print.c: here.
6888 (lookaheadset, shiftset): New, used as additional storage by
6889 print_reductions.
6890 (print_results): Adjust.
6891 (print_shifts, print_gotos, print_errs): New, extracted from...
6892 (print_actions): here.
6893 * src/print_graph.c (print_actions): Remove dead code.
6894
6895 2001-12-27 Akim Demaille <akim@epita.fr>
6896
6897 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
6898 `$n' and `@n'.
6899
6900 2001-12-27 Akim Demaille <akim@epita.fr>
6901
6902 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
6903 (build_relations): Adjust.
6904
6905 2001-12-27 Akim Demaille <akim@epita.fr>
6906
6907 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
6908 duplication.
6909
6910 2001-12-27 Akim Demaille <akim@epita.fr>
6911
6912 * src/reader.c (packgram): Catch nitems overflows.
6913
6914 2001-12-27 Akim Demaille <akim@epita.fr>
6915
6916 * src/files.c, src/files.h (guard_obstack): Remove.
6917 * src/output.c (output): Adjust.
6918 * src/reader.c (parse_braces): New, factoring...
6919 (copy_action, copy_guard): these two which are renamed as...
6920 (parse_action, parse_guard): these.
6921 As a voluntary consequence, using braces around guards is now
6922 mandatory.
6923
6924 2001-12-27 Akim Demaille <akim@epita.fr>
6925
6926 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
6927 * src/reader.c (symbol_list): `guard' and `guard_line' are new
6928 members.
6929 (symbol_list_new): Adjust.
6930 (copy_action): action_line is the first line, not the last.
6931 (copy_guard): Just as for actions, store the `action' only, not
6932 the switch/case/break flesh.
6933 Don't parse the user action that might follow the guard, let...
6934 (readgram): do it, i.e., now, there can be an action after a
6935 guard.
6936 In other words the guard is just explicitly optional.
6937 (packgram): Adjust.
6938 * src/output.c (guards_output): New.
6939 (output_parser): Call it when needed.
6940 (output): Also free the guard and attrs obstacks.
6941 * src/files.c, src/files.h (obstack_save): Remove.
6942 (output_files): Remove.
6943 As a result, if one needs the former `.act' file, using an
6944 appropriate skeleton which requires actions and guards is now
6945 required.
6946 * src/main.c (main): Adjust.
6947 * tests/semantic.at: New.
6948 * tests/regression.at: Use `input.y' as input file name.
6949 Avoid 8+3 problems by requiring input.c when the test needs the
6950 parser.
6951
6952 2001-12-27 Akim Demaille <akim@epita.fr>
6953
6954 * src/reader.c (symbol_list_new): Be sure to initialize all the
6955 fields.
6956
6957 2001-12-27 Akim Demaille <akim@epita.fr>
6958
6959 All the hacks using a final pseudo state are now useless.
6960
6961 * src/LR0.c (set_state_table): state_table holds exactly nstates.
6962 * src/lalr.c (nLA): New.
6963 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
6964 instead of lookaheadsp from the pseudo state (nstate + 1).
6965
6966 2001-12-27 Akim Demaille <akim@epita.fr>
6967
6968 * src/output.c (action_row, token_actions): Use a state_t instead
6969 of a integer, and nlookaheads instead of the following state's
6970 lookaheadsp.
6971
6972 2001-12-27 Akim Demaille <akim@epita.fr>
6973
6974 * src/conflicts.c (log_resolution, flush_shift)
6975 (resolve_sr_conflict, set_conflicts, solve_conflicts)
6976 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
6977 (conflicts_print, print_reductions): Use a state_t instead of an
6978 integer when referring to a state.
6979 As much as possible, depend upon nlookaheads, instead of the
6980 `lookaheadsp' member of the following state (since lookaheads of
6981 successive states are successive, the difference between state n + 1
6982 and n served as the number of lookaheads for state n).
6983 * src/lalr.c (add_lookback_edge): Likewise.
6984 * src/print.c (print_core, print_actions, print_state)
6985 (print_results): Likewise.
6986 * src/print_graph.c (print_core, print_actions, print_state)
6987 (print_graph): Likewise.
6988 * src/conflicts.h: Adjust.
6989
6990 2001-12-27 Akim Demaille <akim@epita.fr>
6991
6992 * src/bison.hairy: Formatting/comment changes.
6993 ANSIfy.
6994 Remove `register' indications.
6995 Add plenty of `static'.
6996
6997 2001-12-27 Akim Demaille <akim@epita.fr>
6998
6999 * src/output.c (prepare): Drop the muscle `ntbase' which
7000 duplicates ntokens.
7001 * src/bison.simple: Formatting/comment changes.
7002 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
7003 is an undocumented synonym.
7004
7005 2001-12-22 Akim Demaille <akim@epita.fr>
7006
7007 * src/output.c (output_table_data): Change the prototype to use
7008 `int' for array ranges: some invocations do pass an int, not a
7009 short.
7010 Reported by Wayne Green.
7011
7012 2001-12-22 Akim Demaille <akim@epita.fr>
7013
7014 Some actions of web2c.y are improperly triggered.
7015 Reported by Mike Castle.
7016
7017 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
7018 * tests/regression.at (Web2c): Rename as...
7019 (Web2c Report): this.
7020 (Web2c Actions): New.
7021
7022 2001-12-22 Akim Demaille <akim@epita.fr>
7023
7024 Reductions in web2c.y are improperly reported.
7025 Reported by Mike Castle.
7026
7027 * src/conflicts.c (print_reductions): Fix.
7028 * tests/regression.at (Web2c): New.
7029
7030 2001-12-18 Akim Demaille <akim@epita.fr>
7031
7032 Some host fail on `assert (!"foo")', which expands to
7033 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
7034 Reported by Nelson Beebee.
7035
7036 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
7037 `#define it_succeeded 0' and `assert (it_succeeded)'.
7038
7039 2001-12-17 Marc Autret <autret_m@epita.fr>
7040
7041 * src/bison.simple: Don't hard code the skeleton line and filename.
7042 * src/output.c (output_parser): Rename 'line' as 'output_line'.
7043 New line counter 'skeleton_line' (skeleton-line muscle).
7044
7045 2001-12-17 Paul Eggert <eggert@twinsun.com>
7046
7047 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
7048 YYDEBUG must be defined to a nonzero value.
7049
7050 * src/bison.simple (yytname): Do not assume that the user defines
7051 YYDEBUG to a properly parenthesized expression.
7052
7053 2001-12-17 Akim Demaille <akim@epita.fr>
7054
7055 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
7056 nlookaheads is a new member.
7057 Adjust all users.
7058 * src/lalr.h (nlookaheads): Remove this orphan declaration.
7059 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
7060 state.
7061
7062 2001-12-17 Akim Demaille <akim@epita.fr>
7063
7064 * src/files.h, src/files.c (open_files, close_files): Remove.
7065 * src/main.c (main): Don't open/close files, nor invoke lex_free,
7066 let...
7067 * src/reader.c (reader): Do it.
7068
7069 2001-12-17 Akim Demaille <akim@epita.fr>
7070
7071 * src/conflicts.c (print_reductions): Formatting changes.
7072
7073 2001-12-17 Akim Demaille <akim@epita.fr>
7074
7075 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
7076 (flush_reduce): New.
7077 (resolve_sr_conflict): Adjust.
7078
7079 2001-12-17 Akim Demaille <akim@epita.fr>
7080
7081 * src/output.c (output_obstack): Be static and rename as...
7082 (format_obstack): this, to avoid any confusion with files.c's
7083 output_obstack.
7084 * src/reader.h (muscle_obstack): Move to...
7085 * src/output.h: here, since it's defined in output.c.
7086
7087 2001-12-17 Akim Demaille <akim@epita.fr>
7088
7089 * src/output.c (action_row, save_column, default_goto)
7090 (sort_actions, matching_state, pack_vector): Better variable
7091 locality.
7092
7093 2001-12-17 Akim Demaille <akim@epita.fr>
7094
7095 * src/output.c: Various formatting changes.
7096
7097 2001-12-17 Akim Demaille <akim@epita.fr>
7098
7099 * src/files.c (output_files): Free the output_obstack.
7100 * src/main.c (main): Call print and print_graph conditionally.
7101 * src/print.c (print): Work unconditionally.
7102 * src/print_graph.c (print_graph): Work unconditionally.
7103 * src/conflicts.c (log_resolution): Output only if verbose_flag.
7104
7105 2001-12-16 Marc Autret <autret_m@epita.fr>
7106
7107 * src/output.c (actions_output): Fix. When we use %no-lines,
7108 there is one less line per action.
7109
7110 2001-12-16 Marc Autret <autret_m@epita.fr>
7111
7112 * src/bison.simple: Remove a useless #line directive.
7113 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
7114 * src/output.c (get_lines_number): New.
7115 (output_parser): Adjust, now takes care about the lines of a
7116 output muscles.
7117 Fix line numbering.
7118 (actions_output): Computes the number of lines taken by actions.
7119 (output_master_parser): Insert new skeleton which is the name of
7120 the output parser file name.
7121
7122 2001-12-15 Marc Autret <autret_m@epita.fr>
7123
7124 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
7125
7126 2001-12-15 Marc Autret <autret_m@epita.fr>
7127
7128 * src/output.c (output_gram): Keep track of the hairy one.
7129
7130 2001-12-15 Akim Demaille <akim@epita.fr>
7131
7132 Make `make distcheck' work.
7133
7134 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
7135 system.h which uses libgettext.h.
7136
7137 2001-12-15 Akim Demaille <akim@epita.fr>
7138
7139 * src/nullable.c (set_nullable): Useless rules must be skipped,
7140 otherwise, since we range over their symbols, we might look at a
7141 nonterminal which no longer ``exists'', i.e., it is not counted in
7142 `nvars', hence we overflow our arrays.
7143
7144 2001-12-15 Akim Demaille <akim@epita.fr>
7145
7146 The header can also be produced directly, without any obstack!
7147 Yahoo!
7148
7149 * src/files.c, src/files.h (defines_obstack): Remove.
7150 (compute_header_macro): Global.
7151 (defines_obstack_save): Remove.
7152 * src/reader.c (parse_union_decl): No longer output to
7153 defines_obstack: its content can be found in the `stype' muscle
7154 anyway.
7155 (output_token_translations): Merge into...
7156 (symbols_output): this.
7157 Rename as...
7158 (symbols_save): this.
7159 (reader): Adjust.
7160 * src/output.c (header_output): New.
7161 (output): Call it.
7162
7163 2001-12-15 Akim Demaille <akim@epita.fr>
7164
7165 * src/reader.c (parse_union_decl): Instead of handling two obstack
7166 simultaneously, use one to define the `stype' muscle, and use the
7167 value of the latter to fill defines_obstack.
7168 (copy_comment): Remove.
7169 (copy_comment2): Work for a single obstack.
7170 Rename as...
7171 (copy_comment): this.
7172
7173 2001-12-15 Akim Demaille <akim@epita.fr>
7174
7175 * src/lex.c, src/lex.h (xgetc): No longer static.
7176 * src/reader.c (parse_union_decl): Revamp.
7177
7178 2001-12-15 Akim Demaille <akim@epita.fr>
7179
7180 Still making progress in separating Bison into (i) input, (ii)
7181 process, (iii) output: now we can directly output the parser file
7182 without using table_obstack at all.
7183
7184 * src/files.c, src/files.h (table_obstack): Bye bye.
7185 (parser_file_name): New.
7186 * src/files.c (compute_output_file_names): Compute it.
7187 * src/output.c (actions_output, output_parser)
7188 (output_master_parser): To a file instead of an obstack.
7189
7190 2001-12-15 Akim Demaille <akim@epita.fr>
7191
7192 Attach actions to rules, instead of pre-outputting them to
7193 actions_obstack.
7194
7195 * src/gram.h (rule_t): action and action_line are new members.
7196 * src/reader.c (symbol_list): Likewise.
7197 (copy_action): Save the actions within the rule.
7198 (packgram): Save them in rule_table.
7199 * src/output.c (actions_output): New.
7200 (output_parser): Use it on `%%actions'.
7201 (output_rule_data): Don't free rule_table.
7202 (output): Do it.
7203 (prepare): Don't save the `action' muscle.
7204 * src/bison.simple: s/%%action/%%actions/.
7205
7206 2001-12-15 Akim Demaille <akim@epita.fr>
7207
7208 * src/reader.c (copy_action): When --yacc, don't append a `;'
7209 to the user action: let it fail if lacking.
7210 Suggested by Arnold Robbins and Tom Tromey.
7211
7212 2001-12-14 Akim Demaille <akim@epita.fr>
7213
7214 * src/lex.c (literalchar): Simply return the char you decoded, non
7215 longer mess around with obstacks and int pointers.
7216 Adjust all callers.
7217
7218 2001-12-14 Akim Demaille <akim@epita.fr>
7219
7220 * src/lex.c (literalchar): Don't escape the special characters,
7221 just decode them, and keep them as char (before, eol was output as
7222 the 2 char string `\n' etc.).
7223 * src/output.c (output_rule_data): Use quotearg to output the
7224 token strings.
7225
7226 2001-12-13 Paul Eggert <eggert@twinsun.com>
7227
7228 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
7229 Do not infringe on the global user namespace when using C++.
7230 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
7231 All uses of `fprintf' and `stderr' changed.
7232
7233 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
7234
7235 2001-12-13 Akim Demaille <akim@epita.fr>
7236
7237 The computation of nullable is broken: it doesn't handle empty
7238 RHS's properly.
7239
7240 * tests/torture.at (GNU AWK Grammar): New.
7241 * tests/sets.at (Nullable): New.
7242 * src/nullable.c (set_nullable): Instead of blindly looping over
7243 `ritems', loop over the rules, and then over their rhs's.
7244
7245 Work around Autotest bugs.
7246
7247 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
7248 frame, because Autotest understand lines starting with a `+' as
7249 traces from the shell. Then, they are not processed properly.
7250 Admittedly an Autotest bug, but we don't have time to wait for
7251 Autotest to catch up.
7252 * tests/regression.at (Broken Closure): Adjust to the new table
7253 frames.
7254 Move to...
7255 * tests/sets.at: here.
7256
7257 2001-12-13 Akim Demaille <akim@epita.fr>
7258
7259 * src/closure.c (closure): Use nrules instead of playing tricks
7260 with BITS_PER_WORD.
7261
7262 2001-12-13 Akim Demaille <akim@epita.fr>
7263
7264 * src/print.c (print_actions): Output the handling of `$' as the
7265 traces do: shifting the token EOF. Before EOF was treated as a
7266 nonterminal.
7267 * tests/regression.at: Adjust some tests.
7268 * src/print_graph.c (print_core): Complete the set of items via
7269 closure. The next-to-final and final states are still unsatisfying,
7270 but that's to be addressed elsewhere.
7271 No longer output the rule numbers, but do output the state number.
7272 A single loop for the shifts + gotos is enough, but picked a
7273 distinct color for each.
7274 (print_graph): Initialize and finalize closure.
7275
7276 2001-12-13 Akim Demaille <akim@epita.fr>
7277
7278 * src/reader.c (readgram): Remove dead code, an strip useless
7279 braces.
7280 (get_type): Remove, unused.
7281
7282 2001-12-12 Akim Demaille <akim@epita.fr>
7283
7284 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
7285 on that of lib/error.c.
7286
7287 2001-12-12 Akim Demaille <akim@epita.fr>
7288
7289 Some hosts don't like `/' in includes.
7290
7291 * src/system.h: Include libgettext.h without qualifying the path.
7292 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
7293 $(top_srcdir).
7294
7295 2001-12-11 Marc Autret <autret_m@epita.fr>
7296
7297 * src/output.c (output_parser): Remove useless muscle.
7298
7299 2001-12-11 Marc Autret <autret_m@epita.fr>
7300
7301 * src/bison.simple: Remove #line just before %%epilogue. It
7302 is now handled in ...
7303 * src/reader.c (read_additionnal_code): Add the output of a
7304 #line for the epilogue.
7305
7306 2001-12-10 Marc Autret <autret_m@epita.fr>
7307
7308 * src/reader.c (copy_definition): Re-use CPP-outed code which
7309 replace precedent remove.
7310 * src/bison.simple: Remove #line before %%prologue because
7311 %%input-line is wrong at this time.
7312
7313 2001-12-10 Marc Autret <autret_m@epita.fr>
7314
7315 * src/reader.c (symbols_output): Clean up.
7316 * src/output.c (output_gram, output): Clean up.
7317
7318 2001-12-10 Akim Demaille <akim@epita.fr>
7319
7320 * src/lalr.c (initialize_lookaheads): New. Extracted from...
7321 * src/LR0.c (set_state_table): here.
7322 * src/lalr.c (lalr): Call it.
7323
7324 2001-12-10 Akim Demaille <akim@epita.fr>
7325
7326 * src/state.h (shifts): Remove the `number' member: shifts are
7327 attached to state, hence no longer need to be labelled with a
7328 state number.
7329
7330 2001-12-10 Akim Demaille <akim@epita.fr>
7331
7332 Now that states have a complete set of members, the linked list of
7333 shifts is useless: just fill directly the state's shifts member.
7334
7335 * src/state.h (shifts): Remove the `next' member.
7336 * src/LR0.c (first_state, last_state): Remove.
7337 Adjust the callers.
7338 (augment_automaton): Don't look for the shifts that must be added
7339 a shift on EOF: it is those of the state we looked for! But now,
7340 since shifts are attached, it is no longer needed to looking
7341 merely by its id: its number.
7342
7343 2001-12-10 Akim Demaille <akim@epita.fr>
7344
7345 * src/LR0.c (augment_automaton): Better variable locality.
7346 Remove an impossible branch: if there is a state corresponding to
7347 the start symbol being shifted, then there is shift for the start
7348 symbol from the initial state.
7349
7350 2001-12-10 Akim Demaille <akim@epita.fr>
7351
7352 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
7353 only when appropriate: when insert_start_shifting_state' is not
7354 invoked.
7355 * tests/regression.at (Rule Line Numbers): Adjust.
7356
7357 2001-12-10 Akim Demaille <akim@epita.fr>
7358
7359 * src/LR0.c (augment_automaton): Now that all states have shifts,
7360 merge the two cases addition shifts to the initial state.
7361
7362 2001-12-10 Akim Demaille <akim@epita.fr>
7363
7364 * src/lalr.c (set_state_table): Move to...
7365 * src/LR0.c: here.
7366 * src/lalr.c (lalr): Don't call it...
7367 * src/LR0.c (generate_states): do it.
7368 * src/LR0.h (first_state): Remove, only the table is used.
7369
7370 2001-12-10 Akim Demaille <akim@epita.fr>
7371
7372 * src/LR0.h (first_shift, first_reduction): Remove.
7373 * src/lalr.c: Don't use first_shift: find shifts through the
7374 states.
7375
7376 2001-12-10 Akim Demaille <akim@epita.fr>
7377
7378 * src/LR0.c: Attach shifts to states as soon as they are
7379 computed.
7380 * src/lalr.c (set_state_table): Instead of assigning shifts to
7381 state, just assert that the mapping was properly done.
7382
7383 2001-12-10 Akim Demaille <akim@epita.fr>
7384
7385 * src/LR0.c (insert_start_shift): Rename as...
7386 (insert_start_shifting_state): this.
7387 (insert_eof_shifting_state, insert_accepting_state): New.
7388 (augment_automaton): Adjust.
7389 Better locality of the variables.
7390 When looking if the start_symbol is shifted from the initial
7391 state, using `while (... symbol != start_symbol ...)' sounds
7392 better than `while (... symbol < start_symbol ...)': If fail
7393 to see how the order between symbols could be relevant!
7394
7395 2001-12-10 Akim Demaille <akim@epita.fr>
7396
7397 * src/getargs.h: Don't declare `spec_name_prefix' and
7398 `spec_file_prefix', declared by src/files.h.
7399 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
7400 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
7401 * src/output.c (prepare): Adjust.
7402 * src/reader.c (symbols_output): Likewise.
7403 * src/vmsgetargs.c: Vaguely adjust, but who cares?
7404
7405 2001-12-10 Akim Demaille <akim@epita.fr>
7406
7407 * src/muscle_tab.c (muscle_init): NULL is a better default than
7408 `"0"'.
7409
7410 2001-12-10 Akim Demaille <akim@epita.fr>
7411
7412 * src/reader.c (reader): Calling symbols_output once is enough.
7413
7414 2001-12-10 Akim Demaille <akim@epita.fr>
7415
7416 Now that states have a complete set of members, the linked list of
7417 reductions is useless: just fill directly the state's reductions
7418 member.
7419
7420 * src/state.h (struct reductions): Remove member `number' and
7421 `next'.
7422 * src/LR0.c (first_reduction, last_reduction): Remove.
7423 (save_reductions): Don't link the new reductions, store them in
7424 this_state.
7425 * src/lalr.c (set_state_table): No need to attach reductions to
7426 states, it's already done.
7427 * src/output.c (output_actions): No longer free the shifts, then
7428 the reductions, then the states: free all the states and their
7429 members.
7430
7431 2001-12-10 Akim Demaille <akim@epita.fr>
7432
7433 * src/options.c (OPTN, DRTV, BOTH): New.
7434 (option_table): Use them.
7435
7436 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
7437 the job of system.h.
7438 * src/options.c: Don't include stdio.h and xalloc.h for the same
7439 reasons.
7440
7441 2001-12-10 Akim Demaille <akim@epita.fr>
7442
7443 * src/output.c (output, prepare): Make sure the values of the
7444 muscles `action' and `prologue' are 0-terminated.
7445
7446 2001-12-10 Akim Demaille <akim@epita.fr>
7447
7448 Clean up GCC warnings.
7449
7450 * src/reader.c (copy_action): `buf' is not used.
7451 (parse_skel_decl): Be static.
7452 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
7453 * src/options.h (create_long_option_table): Have a real prototype.
7454 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
7455 (hash_delete_at): Return const void *.
7456 Adjust casts to preserve the const.
7457
7458 2001-12-10 Akim Demaille <akim@epita.fr>
7459
7460 * configure.in: Require 2.52g.
7461 M4 is not needed, but AUTOM4TE is.
7462 * m4/m4.m4: Remove.
7463 * tests/Makefile.am: Adjust.
7464
7465 2001-12-10 Akim Demaille <akim@epita.fr>
7466
7467 One structure for states is enough, even though theoretically
7468 there are LR(0) states and LALR(1) states.
7469
7470 * src/lalr.h (state_t): Remove.
7471 (state_table): Be state_t **, not state_t *.
7472 * src/state.h (core, CORE_ALLOC): Rename as...
7473 (state_t, STATE_ALLOC): this.
7474 Add the LALR(1) members: shifts, reductions, errs.
7475 * src/LR0.c (state_table): Rename as...
7476 (state_hash): this, to avoid name clashes with the global
7477 `state_table'.
7478 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
7479 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
7480
7481 2001-12-10 Akim Demaille <akim@epita.fr>
7482
7483 Bison dumps core on bash.y.
7484 Reported by Pascal Bart.
7485
7486 * src/warshall.c (bitmatrix_print): New.
7487 (TC): Use it.
7488 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
7489 j must be the outer loop.
7490 * tests/regression.at (Broken Closure): New.
7491
7492 2001-12-05 Akim Demaille <akim@epita.fr>
7493
7494 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
7495 its argument.
7496 Reported by Peter Hamorsky.
7497
7498 2001-12-05 Akim Demaille <akim@epita.fr>
7499
7500 * src/conflicts.c (err_table): Remove.
7501 (resolve_sr_conflict): Adjust.
7502 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
7503 Rename as...
7504 (state_t.reductions, state_t.shifts): this.
7505
7506 2001-12-05 Akim Demaille <akim@epita.fr>
7507
7508 * src/reduce.c (reduce_grammar_tables): No longer disable the
7509 removal of useless rules via CPP but via `if (0)', so that the
7510 compiler still check the code is valid.
7511 For instance, it should have noticed `rline' no longer exists: use
7512 the `line' member of rule_t.
7513 * src/gram.c (dummy, rline): Remove, unused.
7514
7515 2001-12-05 Akim Demaille <akim@epita.fr>
7516
7517 * src/output.c (pack_vector): Use assert, not berror.
7518 * src/main.c (berror): Remove, unused.
7519
7520 2001-12-05 Akim Demaille <akim@epita.fr>
7521
7522 New experimental feature: if --verbose --trace output all the
7523 items of a state, not only its kernel.
7524
7525 * src/print.c (print_core): If `trace_flag', then invoke closure
7526 before outputting the items of the state (print_core is no longer
7527 a correct name them).
7528 (print_results): Invoke new_closure/free_closure if needed.
7529
7530 2001-12-05 Akim Demaille <akim@epita.fr>
7531
7532 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
7533 * src/closure.c, src/closure.h (itemsetsize): Rename as...
7534 (nitemset): for consistency with the rest of the project.
7535
7536 2001-12-05 Akim Demaille <akim@epita.fr>
7537
7538 * src/closure.c (print_closure): Improve.
7539 (closure): Use it for printing input and output.
7540
7541 2001-12-05 Akim Demaille <akim@epita.fr>
7542
7543 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
7544 indexed by nonterminals.
7545
7546 2001-12-05 Akim Demaille <akim@epita.fr>
7547
7548 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
7549 what it was!).
7550 * src/warshall.h: Remove accidental duplication of the content.
7551
7552 2001-12-05 Akim Demaille <akim@epita.fr>
7553
7554 * src/closure.c (set_fderives): De-obfuscate.
7555
7556 2001-12-05 Akim Demaille <akim@epita.fr>
7557
7558 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
7559
7560 2001-12-05 Akim Demaille <akim@epita.fr>
7561
7562 * src/closure.c (set_firsts): De-obfuscate.
7563
7564 2001-12-05 Akim Demaille <akim@epita.fr>
7565
7566 * src/output.c (action_row): De-obfuscate
7567 using the good o' techniques: arrays not pointers, variable
7568 locality, BITISSET, RESETBIT etc.
7569
7570 2001-12-05 Akim Demaille <akim@epita.fr>
7571
7572 Pessimize the code to simplify it: from now on, all the states
7573 have a valid SHIFTS, which NSHIFTS is possibly 0.
7574
7575 * src/LR0.c (shifts_new): Be global and move to..
7576 * src/state.c, src/state.h: here.
7577 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
7578 * src/print_graph: Adjust.
7579
7580 2001-12-05 Akim Demaille <akim@epita.fr>
7581
7582 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
7583 * src/conflicts.c: Use it.
7584 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
7585 incorrectly ``simplified''.
7586
7587 2001-12-05 Akim Demaille <akim@epita.fr>
7588
7589 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
7590 using the good o' techniques: arrays not pointers, variable
7591 locality, BITISSET, RESETBIT etc.
7592
7593 2001-12-05 Akim Demaille <akim@epita.fr>
7594
7595 * src/state.h (SHIFT_SYMBOL): New.
7596 * src/conflicts.c: Use it to deobfuscate.
7597
7598 2001-12-05 Akim Demaille <akim@epita.fr>
7599
7600 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
7601 (print_reductions): De-obfuscate using the good o' techniques:
7602 arrays not pointers, variable locality, BITISSET.
7603
7604 2001-12-05 Akim Demaille <akim@epita.fr>
7605
7606 * src/conflicts.c (print_reductions): Arrays, not pointers.
7607 Use BITISSET.
7608
7609 2001-12-05 Akim Demaille <akim@epita.fr>
7610
7611 * src/conflicts.c (print_reductions): Pessimize, but clarify.
7612
7613 2001-12-05 Akim Demaille <akim@epita.fr>
7614
7615 * src/conflicts.c (print_reductions): Improve variable locality.
7616
7617 2001-12-05 Akim Demaille <akim@epita.fr>
7618
7619 * src/conflicts.c (print_reductions): Pessimize, but clarify.
7620
7621 2001-12-05 Akim Demaille <akim@epita.fr>
7622
7623 * src/conflicts.c (print_reductions): Improve variable locality.
7624
7625 2001-12-05 Akim Demaille <akim@epita.fr>
7626
7627 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
7628 * src/lalr.c: Use them.
7629
7630 2001-12-05 Akim Demaille <akim@epita.fr>
7631
7632 * src/LR0.c (augment_automaton): Formatting changes.
7633 Better variable locality.
7634
7635 2001-12-05 Akim Demaille <akim@epita.fr>
7636
7637 * src/lalr.c (matrix_print): New.
7638 (transpose): Use it.
7639 Use arrays instead of pointers.
7640
7641 2001-12-05 Akim Demaille <akim@epita.fr>
7642
7643 * src/lalr.c (maxrhs): Move to...
7644 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
7645 * src/lalr.c (build_relations): Adjust.
7646
7647 2001-12-05 Akim Demaille <akim@epita.fr>
7648
7649 * src/lalr.c (transpose): Free the memory allocated to the
7650 argument, as it is replaced by the results by the unique caller.
7651 (build_relations): Merely invoke transpose: it handles the memory
7652 deallocation.
7653 Improve variable locality.
7654 Avoid variables used as mere abbreviations.
7655 (compute_lookaheads): Use arrays instead of pointers.
7656
7657 2001-12-05 Akim Demaille <akim@epita.fr>
7658
7659 * src/lalr.c (initialize_F): Improve variable locality.
7660 Avoid variables used as mere abbreviations.
7661
7662 2001-12-05 Akim Demaille <akim@epita.fr>
7663
7664 * src/derives.c (print_derives): Display the ruleno.
7665 * src/lalr.c (initialize_F, transpose): Better variable locality
7666 to improve readability.
7667 Avoid variables used as mere abbreviations.
7668
7669 2001-12-05 Akim Demaille <akim@epita.fr>
7670
7671 * src/lalr.c (traverse): Use arrays instead of pointers.
7672
7673 2001-12-05 Akim Demaille <akim@epita.fr>
7674
7675 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
7676 the handling of squeue.
7677 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
7678
7679 2001-12-05 Akim Demaille <akim@epita.fr>
7680
7681 Because useless nonterminals are now kept alive (instead of being
7682 `destroyed'), we now sometimes examine them, and store information
7683 related to them. Hence we need to know their number, and adjust
7684 memory allocations.
7685
7686 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
7687 static.
7688 * src/LR0.c (allocate_itemsets): The memory allocated to
7689 `symbol_count' was used for two different purpose: once to count
7690 the number of occurrences of each symbol, and later reassigned to
7691 `shift_symbol', containing the symbol that can be shifted from a
7692 given state.
7693 Deobfuscate, i.e., allocate, use and free `symbol_count' here
7694 only, and...
7695 (new_itemsets): Allocate `shift_symbol' here.
7696 (allocate_itemsets): symbol_count includes useless nonterminals.
7697 Make room for them.
7698 (free_storage): Use `free', not `XFREE', for pointers that cannot
7699 be null.
7700
7701 2001-12-05 Akim Demaille <akim@epita.fr>
7702
7703 * src/nullable.c (set_nullable): Deobfuscate the handling of
7704 ritem.
7705 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
7706
7707 2001-12-05 Akim Demaille <akim@epita.fr>
7708
7709 * src/gram.c, src/gram.h (ritem_print): New.
7710 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
7711 (This useless function was defined only to work around VMS linkers
7712 that can't handle compilation units with variables only).
7713 * src/reduce.c (dump_grammar): Use it to trace the construction of
7714 ritem.
7715
7716 2001-12-04 Paul Eggert <eggert@twinsun.com>
7717
7718 * src/bison.simple (union yyalloc): Change member names
7719 to be the same as the stack names.
7720 (yyparse): yyptr is now union yyalloc *, not char *.
7721 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
7722 and may generate better code on some machines.
7723 (yystpcpy): Use prototype if __STDC__ is defined, not just
7724 if __cplusplus is defined.
7725
7726 2001-11-30 Akim Demaille <akim@epita.fr>
7727
7728 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
7729 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
7730 Gettext doesn't compile cleanly, and dies with -Werror.
7731 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
7732 Include WARNING_CFLAGS here.
7733 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
7734 before being defined.
7735
7736 2001-11-27 Paul Eggert <eggert@twinsun.com>
7737
7738 * lib/quotearg.h (quotearg_n, quotearg_n_style):
7739 First arg is int, not unsigned.
7740 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
7741 (SIZE_MAX, UINT_MAX): New macros.
7742 (quotearg_n_options): Abort if N is negative.
7743 Avoid overflow check on hosts where size_t is 64 bits and int
7744 is 32 bits, as overflow is impossible there.
7745 Fix off-by-one typo that caused unnecessary reallocation.
7746
7747 2001-11-29 Paul Eggert <eggert@twinsun.com>
7748
7749 Name space cleanup in generated parser.

7757 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).

7760 on user names when possible.

7763 Simplify test for whather <alloca.h> exists.

7800
7801 Instead of mapping the LHS of unused rules to -1, keep the LHS

7803
7804 * src/gram.h (rule_t): `useful' is a new member.
7805 * src/print.c (print_grammar): Adjust.
7806 * src/derives.c (set_derives): Likewise.

7839 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
7840 an arbitrary restriction on hosts where size_t is wider than int.
7841
7842 (yyparse): Don't dump core if alloca or malloc fails; instead, report
7843 a parser stack overflow. Allocate just one block of memory for all
7844 three stacks, instead of allocating three blocks; this typically is
7845 faster and reduces fragmentation.
7846
7847 Do not limit the number of items in the stack to a value that fits
7848 in 'int', as this is an arbitrary limit on hosts with 64-bit
7849 size_t and 32-bit int.

7910

8305 * src/lex.c (parse_percent_token): Replace equal_offset with

9661 New, from fileutils 4.0.37.
9662 * configure.in: Require Autoconf 2.49c. I took some time before

9664 issues in Bison, it would mean way too much duplicate effort to
9665 import in Bison features implemented in 2.49c since 2.13.
9666 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
9667

9682
9683 2001-01-19 Akim Demaille <akim@epita.fr>
9684
9685 * src/lex.h: Rename all the tokens:
9686 s/\bENDFILE\b/tok_eof/g;

9701 * src/lex.c (percent_table): Also accept `%yacc',
9702 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

9704 Handle the actions for `%semantic_parser' and `%pure_parser' here,
9705 instead of returning a token.
9706 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
9707 * src/reader.c (read_declarations): Adjust.
9708 * src/files.c (open_files): Don't call `compute_base_names', don't
9709 compute `attrsfile' since they depend upon data which might be
9710 *in* the input file now.
9711 (output_files): Do it here.
9712 * src/output.c (output_headers): Document the fact that this patch
9713 introduces a guaranteed SEGV for semantic parsers.
9714 * doc/bison.texinfo: Document them.

9735
9736 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

9738 FILE * parameters.
9739
9740 2000-12-20 Akim Demaille <akim@epita.fr>
9741
9742 * src/files.c (open_files): Actually the `.output' file is based

9772 (stringappend): Be just like strcat but allocate.
9773 (base_names): Eve out from open_files.
9774 Try to simplify the rather hairy computation of base_name and
9775 short_base_name.
9776 (open_files): Use it.
9777 * tests/suite.at (Checking output file names): New test.
9778

9814
9815 2000-12-19 Akim Demaille <akim@epita.fr>
9816
9817 * src/files.c (open_files): Yipee! We no longer need all the code

9850 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
9851 prevents type checking.
9852 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

9902 Qualify it `const'.
9903 (obstack_copy, obstack_copy0): Rename the second argument as
9904 `address' for consistency. Qualify it `const'.
9905 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
9906 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
9907 `const' their input argument (`data' or `address').

10042
10043 When a literal string is used to define two different tokens,
10044 `bison -v' segfaults.
10045 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
10046
10047 * tests/regression.m4: New file.
10048 Include the core of the sample provided by Piotr Gackiewicz.
10049 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
10050 properly.
10051
10052 2000-10-04 Akim Demaille <akim@epita.fr>
10053
10054 * src/reader.c (parse_expect_decl): Keep `count' within the size
10055 of `buffer'.
10056 From Neil Booth.
10057
10058 2000-10-02 Paul Eggert <eggert@twinsun.com>
10059
10060 * bison.s1 (yyparse): Assign the default value
10061 unconditionally, to avoid a GCC warning and make the parser a
10062 tad smaller.
10063
10064 2000-10-02 Akim Demaille <akim@epita.fr>
10065
10066 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
10067 options.
10068
10069 2000-10-02 Akim Demaille <akim@epita.fr>
10070
10071 * src/derives.c, src/print.c, src/reduce.c: To ease the
10072 translation, move some `\n' out of the translated strings.
10073
10074 2000-10-02 Akim Demaille <akim@epita.fr>
10075
10076 The location tracking mechanism is precious for parse error
10077 messages. Nevertheless, it is enabled only when `@n' is used in
10078 the grammar, which is a different issue (you can use it in error
10079 message, but not in the grammar per se). Therefore, there should
10080 be another means to enable it.
10081
10082 * src/getargs.c (getargs): Support `--locations'.
10083 (usage): Report it.
10084 * src/getargs.h (locationsflag): Export it.
10085 * src/lex.c (percent_table): Support `%locations'.
10086 * src/reader.c (yylsp_needed): Remove this variable, now replaced
10087 with `locationsflag'.
10088 * doc/bison.texinfo: Document `--locations' and `%locations'.
10089 Sort the options.
10090 * tests/calc.m4: Test it.
10091
10092 For regularity of the names, replace each
10093 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
10094 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
10095 In addition replace each `flag' with `_flag'.
10096
10097 2000-10-02 Akim Demaille <akim@epita.fr>
10098
10099 Also test parse error messages, including with YYERROR_VERBOSE.
10100
10101 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
10102 associative).
10103 Use it to check the computations.
10104 Use it to check `nonassoc' is honored.
10105 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
10106 `--yyerror-verbose'.
10107 (_AT_CHECK_CALC): Adjust to this option.
10108 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
10109
10110 2000-10-02 Akim Demaille <akim@epita.fr>
10111
10112 Test also `--verbose', `--defines' and `--name-prefix'. Testing
10113 the latter demonstrates a flaw in the handling of non debugging
10114 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
10115 was used in order to simplify:
10116
10117 #if YYDEBUG
10118 if (yydebug)
10119 {
10120 ...
10121 }
10122 #endif
10123
10124 into
10125
10126 if (yydebug)
10127 {
10128 ...
10129 }
10130
10131 unfortunately this leads to a CPP conflict when
10132 `--name-prefix=foo' is used since it produces `#define yydebug
10133 foodebug'.
10134
10135 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
10136 (YYDPRINTF): New macro.
10137 Spread its use.
10138 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
10139 the bison options.
10140 Also test `--verbose', `--defines' and `--name-prefix'.
10141
10142 2000-10-02 Akim Demaille <akim@epita.fr>
10143
10144 Improve the readability of the produced parsers.
10145
10146 * src/bison.s1: Formatting changes.
10147 Improve the comment related to the `$' mark.
10148 (yydefault): Don't fall through to `yyresume': `goto' there.
10149 * src/output.c (output_parser): When the `$' is met, skip the end
10150 of its line.
10151 New variable, `number_of_dollar_signs', to check there's exactly
10152 one `$' in the parser skeleton.
10153
10154 2000-10-02 Akim Demaille <akim@epita.fr>
10155
10156 * lib/xstrdup.c: New file, from the fileutils.
10157 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
10158 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
10159 instead of strlen + xmalloc + strcpy.
10160 * src/symtab.c (copys): Remove, use xstrdup instead.
10161
10162 2000-10-02 Akim Demaille <akim@epita.fr>
10163
10164 * src/gram.h (associativity): New enum type which replaces the
10165 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
10166 `right_assoc', `left_assoc' and `non_assoc'.
10167 Adjust all dependencies.
10168 * src/reader.c: Formatting changes.
10169 (LTYPESTR): Don't define it, use it as a literal in
10170 `reader_output_yylsp'.
10171 * src/symtab.h (symbol_class): New enum type which replaces the
10172 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
10173 `sunknown', `stoken and `snterm'.
10174
10175 2000-10-02 Akim Demaille <akim@epita.fr>
10176
10177 * src/getargs.c (fixed_outfiles): Rename as...
10178 (yaccflag): for consistency and accuracy.
10179 Adjust dependencies.
10180
10181 2000-10-02 Akim Demaille <akim@epita.fr>
10182
10183 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
10184 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
10185 difficult and introduced a lot of core dump. It turns out that
10186 Bison used an implementation of `xmalloc' based on `calloc', and
10187 at various places it does depend upon the initialization to 0. I
10188 have not tried to isolate the pertinent places, and all the former
10189 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
10190 someone should address this issue.
10191
10192 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
10193 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

10289 output_short_table.
10290
10291 2000-10-02 Akim Demaille <akim@epita.fr>
10292
10293 `user_toknums' is output as a `short[]' in `output.c', while it is
10294 defined as a `int[]' in `reader.c'. For consistency with the
10295 other output tables, `user_toknums' is now defined as a table of
10296 shorts.

10337 inclusion.
10338 Don't define PARAMS.
10339 * src/system.h: Define PARAMS.

10560 Change the handling of @s so that they behave exactly like $s.
10561 There is now a pseudo variable @$ (readble and writable), location
10562 of the lhs of the rule (by default ranging from the location of
10563 the first symbol of the rhs, to the location of the last symbol,
10564 or, if the rhs is empty, YYLLOC).

10568 (yyparse): When providing a default semantic action, provide a

10599 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
10600 One `#if YYDEBUG' remains, since it uses variables which are
10601 defined only if `YYDEBUG != 0'.
10602
10603 2000-03-16 Akim Demaille <akim@epita.fr>

10641 * m4/Makefile.am (EXTRA_DIST): New variable.

11327 way to specify the flags -n, -l, and -r. Also added hooks for
