19
20 * doc/bison.texinfo: Use "location" consistently to refer to @n,

28 (location.hh): Use consistent variable names when defining the
29 operator<<.
30 Use "last" so that we subtract from Positions, not from unsigned.

72
73 * tests/atlocal.in (LDFLAGS, LIBS): New vars.

80 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
81 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
82 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
83 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
84 Check for malloc failure, for consistency with yacc.c.
85 (yytname_size): Remove, for consistency with yacc.c.
86
87 The bug still remains in data/lalr1.cc, as I didn't have time
88 to fix it there.

902003-02-06 Akim Demaille <akim@epita.fr>
91
92 * configure.ac (GXX): Rename as...
93 (CXX): this, to keep the original Autoconf semantics.

115 Conform to the GCS: simplify the locations when applicable.
116 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
117 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
118 these CPP macros with the m4 macros new defined by...
119 (AT_CHECK_PUSHDEFS): this, i.e.:
120 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)

139 * src/gram.h (start_symbol): Remove unused decl.
140
141 Use more-consistent naming conventions for local vars.
142
143 * src/derives.c (derives_compute): Change type of local var from
144 int to rule_number.
145 * src/gram.c (grammar_rules_partial_print): Likewise.
146 * src/print.c (print_core): Likewise.
147 * src/reduce.c (reduce_grammar_tables): Likewise.
148
149 * src/gram.c (grammar_dump): Change name of item_number *
150 local var from r to rp.
151 * src/nullable.c (nullable_compute): Likewise.

170 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
171 var.
172
173 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
174 Use str, not s, for char * var. Use ch, not c, for character var.

178 char * var.
179 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for

186 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
187 param to have same name as that of enum, so that we don't use
188 "s" to stand for a non-state.

0435d061 213

214 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
215 (b4_rhs_location): Ditto.
0435d061 216 (yyfill): New function to copy from stack tree into array
6029a57f 217 incrementally.
0435d061
AD
218 (yyuserAction): Modify to allow incremental move of semantic values
219 to rhs array when in GLR mode.
220 Define YYFILL to use in user-defined actions to fill semantic array
6029a57f
PH
221 as needed.
222 Remove dummy use of yystack, as there is now a guaranteed use.
223 (yydoAction): Modify to allow incremental move of semantic values
224 to rhs array when in GLR mode.
225 (yyresolveAction): Ditto.
226 (yyglrShiftDefer): Update comment.
0435d061 227 (yyresolveStates): Use X == NULL for pointers, not !X.

2382003-01-28 Paul Eggert <eggert@twinsun.com>
239
240 * data/lalr1.cc: Do not use @output_header_name@ unless
241 b4_defines_flag is set. This fixes two bugs reported by
242 Tim Van Holder in
243 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
244 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.

PE
2462003-01-21 Paul Eggert <eggert@twinsun.com>
247
248 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
249 we don't need to worry about yyerrlab1 being reported as an
250 "unused label" by non-GCC C compilers. The downside is that if
251 locations are used then a couple of statements are duplicated each
252 time YYERROR is invoked, but the upside is that the warnings
253 should vanish.
254 (yyerrlab1): Move code to YERROR.
255 (yyerrlab2): Remove. Change uses back to yyerrlab1.
256 This reverts some of the 2002-12-27 change.

2582003-01-17 Paul Eggert <eggert@twinsun.com>

260 * src/output.c (symbol_printers_output): Fix typo that led
261 to core dump. Problem reported by Antonio Rus in
262 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.

266 Robert Anisko <anisko_r@lrde.epita.fr>
267
268 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
269 when the stacks contain one element, as the loop would otherwise
270 free the last state, and then use the top state (the one we just
271 popped). This means that the initial elements will not be freed
272 explicitly, as is the case in yacc.c; it is not a problem, as
273 these elements have fake values.

2752003-01-11 Paul Eggert <eggert@twinsun.com>
276
277 * NEWS: %expect-violations are now just warnings, reverting
278 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
279 bootstrapping problem reported by Matthias Klose; see
280 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
281 * src/conflicts.c (conflicts_print): Likewise.
282 * tests/conflicts.at (%expect not enough, %expect too much,
283 %expect with reduce conflicts): Likewise.
284 * doc/bison.texinfo (Expect Decl): Document this. Also mention
285 that the warning is enabled if the number of conflicts changes
286 (not necessarily increases).
287
288 * src/getargs.c (version): Update copyright year.

AD
2902003-01-09 Akim Demaille <akim@epita.fr>

PE
2942003-01-08 Paul Eggert <eggert@twinsun.com>
295
296 * Makefile.maint (WGETFLAGS):
297 New macro, containing "-C off" to disable proxy caches.
298 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
299 (rel-check): Use $(WGET) instead of wget.

3012003-01-06 Paul Eggert <eggert@twinsun.com>

311 (EXTRA_LIBRARIES): New var, for liby.a.
312 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
313 (EXTRA_SCRIPTS): New var, for yacc.
314
464c6927
PE
315 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
316 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
317 Problem reported by Nelson H. F. Beebe.
318
3192003-01-03 Paul Eggert <eggert@twinsun.com>
320
321 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
322 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
323 when compiling Bison 1.875's `bitset bset = obstack_alloc
324 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
325
326 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
327 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
328 grow to a huge size with typical invocation.
d600ee67 329
464c6927
PE
330 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
331 Use the pattern recommended by Autoconf 2.57, except also protect
332 against double-definition.
333 * src/system.h: Likewise.
334 Portability issues reported by Nelson H. F. Beebe.
d600ee67 335
464c6927
PE
336 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
337 All uses changed. Provide a definition in both C and C++.
338 (yytrue, yyfalse): Define even if defined (__cplusplus).
339
340 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
341 Reported by Nelson H. F. Beebe.
d600ee67 342

PE
343 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.

3452003-01-02 Paul Eggert <eggert@twinsun.com>
346
347 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
348 pacify the buggy "smart preprocessor" in MacOS 10.2.3.

3552002-12-30 Paul Eggert <eggert@twinsun.com>
356
357 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
358 Moved here from...
359 (<INITIAL>","): Here. This causes stray "," to be treated
360 more uniformly.
361
dc546b0f 362 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
2c09b6a7
PE
363 last brace in braced code when not in Yacc mode, for compatibility
364 with Bison 1.35. This resurrects the 2001-12-15 patch to
365 src/reader.c.
366
367 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
368 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.

PE
3702002-12-28 Paul Eggert <eggert@twinsun.com>

377
378 Version 1.75f.
379
380 Switch back to the Yacc style of conflict reports, undoing some
381 of the 2002-07-30 change.
382 * doc/bison.texinfo (Understanding): Use Yacc style for
383 conflict reports. Also, use new way of locating rules.
384 * src/conflicts.c (conflict_report):
385 Renamed from conflict_report_yacc, removing the old
386 'conflict_report'. Translate the entire conflict report at once,
387 so that we don't assume that "," has the same interpretation in
388 all languages.
389 (conflicts_output): Use Yacc-style conflict report for each state,
390 instead of our more-complicated style.
391 (conflicts_print): Use Yacc-style conflict report, except print
392 the input file name when not emulating Yacc.
393 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
394 Conflicted Reduction, %expect not enough, %expect too much,
395 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
396 * tests/existing.at (GNU Cim Grammar): Likewise.
397 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
398
399 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
400 fatal): Don't invoke fflush; it's not needed and it might even be
401 harmful for stdout, as stdout might not be open.
402 * src/reduce.c (reduce_print): Likewise.

406 Fix a bug where error locations were not being recorded correctly.
407 This problem was originally reported by Paul Hilfinger in
e3aa65c5 408 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.

PE
409
410 * data/yacc.c (yyparse): New local var yylerrsp, to record the
411 top of the location stack's error locations.
412 (yyerrlab): Set it. When discarding a token, push its location
413 onto yylerrsp so that we don't lose track of the error's end.
414 (yyerrlab1): Now is only the target of YYERROR, so that we can

416 2.93 and later, insert an __attribute__ ((__unused__)) to avoid

482 If the user does not define YYSTYPE as a macro, Bison now declares it
483 using typedef instead of defining it as a macro. POSIX requires this.
484 For consistency, YYLTYPE is also declared instead of defined.
485
486 %union directives can now have a tag before the `{', e.g., the
487 directive `%union foo {...}' now generates the C code
488 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
489 The default union tag is `YYSTYPE', for compatibility with Solaris 9
490 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
491 instead of `yyltype'.
492
493 `yystype' and `yyltype' are now obsolescent macros instead of being
494 typedefs or tags; they are no longer documented and will be
495 withdrawn in a future release.
496
497 * data/glr.c (b4_location_type): Remove.

504 * data/yacc.c: Likewise.
505

507 does not specify a union tag. This is for compatibility with
508 Solaris 9 yacc.
509
510 * src/parse-gram.y (add_param): 2nd arg is now char * not char

1240 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
1241 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
1242 Group compiler. Instead, use "$CC -E bar.c". Include the .h
1243 file twice in the grammar, as an extra check.
1244
1245 * tests/input.at (Torturing the Scanner): Surround the
1246 backslash-newline tests with "#if 0", to make it less likely that
1247 we'll run into compiler bugs. Bring back solitary \ inside
1248 comment, but add a closing comment to work around HP C bug. Don't
e3aa65c5 1249 test backslash-newline in C character constant.

1274 samples, additional @group/@end group, GCS in samples.
1275 Use @deffn instead of simple @table to define the directives,
1276 macros, variables etc.

18b519c0 1282
daa33def 1283 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
8fcc7db1 1284 -o c"; the HP C compiler chatters during compilation.
daa33def
PE
1285 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
1286 * tests/headers.at (export YYLTYPE): Likewise.
1287
1288 * tests/input.at (Torturing the Scanner): Remove lines containing
8fcc7db1 1289 solitary backslashes, as they tickle a bug in the HP C compiler.

1305
1306 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
1307 (yyglrReduce): Return yyok, not 0.
1308 This should avoid the enumerated-type warnings reported
464c6927 1309 by Nelson H. F. Beebe in

1314 (bitset_set, bitset_reset, bitset_test): Rename local vars
1315 to avoid shadowing warnings by GCC.
1316
1317 * data/glr.c (inline): Remove #define. It's the user's
1318 responsibility to #define it away, just like 'const'.
464c6927 1319 This fixes one of the bugs reported by Nelson H. F. Beebe in
e3aa65c5 1320 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.

1322 * Makefile.maint (po-check): Scan .l and .y files instead of the
1323 .c and the .h files that they generate. This fixes the bug

1326 Look for N_ as well as for _. Try to avoid matching #define for
1327 N_ and _.
1328 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
1329 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
1330 * src/scan-gram.l: Revamp regular expressions so that " and '
1331 do not confuse xgettext.
1332
1333 * src/struniq.h (struniq_new): Do not declare the return type
1334 to be 'const'; this violates the C standard.

1389 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
1390 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
1391 it against YYEMPTY and so forth), work on yytoken (i.e., set
1392 it to YYEMPTY etc.).
1393 (yydestruct): Replace with a b4_yydestruct_generate invocation.
1394 (b4_symbol_actions): Remove.

1437
1438 Use struniq for symbols.
1439

1441 (symbol_type_set): Adjust.
1442 * src/symtab.c (symbol_new): Takes a struniq.
1443 (symbol_free): Don't free the tag member.

1483 Revamp to fix many (but not all) of the C- and M4-related quoting
1484 problems. Among other things, this fixes the Bison bug reported
1485 by Jan Hubicka when processing the Bash grammar; see:

1487
1488 Use new @ escapes consistently. Represent brackets with @{ and @}
1489 rather than @<:@ and @:>@, since this works a bit better with dumb
1490 editors like vi. Represent @ with @@, since @ is now consistently
1491 an escape. Use @oline@ and @ofile@ rather than __oline__ and
1492 __ofile__, to avoid unexpected expansions. Similarly, use @output
1493 rather than #output.
1494
1495 * data/c.m4 (b4_copyright): Omit file name from comment, since
1496 the file name could contain "*/".
1497 (b4_synclines_flag): Don't quote the 2nd argument; it should already
1498 be quoted. All uses changed.
1499
1500 * data/glr.c: Use new @ escapes consistently.
1501 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
1502 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
1503 Remove, since they couldn't handle arbitrary characters in file
1504 names.
1505 * data/lalr1.cc: Likewise.
1506 * data/yacc.c: Likewise.
1507
1508 * src/files.c (output_infix): Remove; all uses removed.
1509 * src/files.h: Likewise.
1510
1511 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
1512 mishandled funny characters in file names, and anyway it isn't
1513 needed any more.
1514 * data/yacc.c: Likewise.
1515 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
1516
1517 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
1518 * data/yacc.c: Likewise.
1519
1520 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
1521 strings now.
1522 (muscle_init): Quote filename as a C string.
1523 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
1524 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
1525 * src/output.c (escaped_file_name_output): New function.
1526 (prepare_symbols): Quote tokens for M4.
1527 (prepare): Don't insert output_infix, output_prefix,
1528 output_parser_name, output_header_name; this is now down by scan-skel.
1529 Insert skeleton as a C string.
1530
1531 * src/output.c (user_actions_output, symbol_destructors_output,
1532 symbol_printers_output): Quote filenames for C and M4.
1533 * src/reader.c (prologue_augment, epilogue_set): Likewise.
1534
1535 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
1536 escapes other than \\ and \'; this simplifies the code.
1537 (<SC_STRING>): Likewise, for \\ and \".
1538 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
1539 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
1540 Use new escapes @{ and @} for [ and ].
1541
1542 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
1543 them with auto vars.
1544 Switch to new escape scheme, where @ is the escape character uniformly.
1545 Abort if a stray escape character is found. Avoid unbounded input
1546 buffer when parsing non-escaped text.
1547
1548 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
1549 __oline__, #output, $@, and @{ do not have unintended meanings.

PE
1555 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
1556 evaluate to 0 if it's impossible for NINF to be in the respective
1557 table.
1558 (yygetLRActions, yyrecoverParseError): Use them.
1559
1560 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
1561 counted in the token inserted at end of file. Now takes
1562 location_t *, not location_t, so that the location can be
1563 adjusted. All uses changed.
1564
1565 * tests/regression.at (Invalid inputs): Adjust wording in
1566 diagnostic to match the new behavior.
1567
1568 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
1569 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
1570 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
1571 abort ();'. This reduces the runtime of the "Many lookaheads"
1572 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
1573 GCC 3.2.

1577 * src/parse-gram.y (CHARACTER): Remove unused token.
1578 All uses removed.
1579
1580 * src/scan-gram.l: Remove stack option. We no longer use the
1581 stack, since the stack was never deeper than 1; instead, use the
1582 new auto var c_context to record the stacked value.
1583
1584 Remove nounput option. At an unexpected end of file, we now unput
1585 the minimal input necessary to end cleanly; this simplifies the
1586 code.
1587
1588 Avoid unbounded token sizes where this is easy.
1589
1590 (unexpected_end_of_file): New function.
1591 Use it to systematize the error message on unexpected EOF.
1592 (last-string): Now auto, not static.
1593 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
1594 (scanner_last_string_free): Remove; not used.
1595 (percent_percent_count): Move decl to just before use.
1596 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
1597 not the (never otherwised-used) CHARACTER.

1900 The last OS that we could find where this wouldn't work is
1901 SunOS 3.5, and that's too old to worry about now.
1902
1903 * data/glr.c (struct yyltype): Define members even when not
1904 doing locations. This is more consistent with yacc.c, and it

2031 Do not create a temporary file, as that involves security and
2032 cleanup headaches. Instead, use a pair of pipes.
2033 Derived from a suggestion by Florian Krohm.

2277 Let nondeterministic skeletons be usable with deterministic
2278 tables.
2279
2280 With the patch, GAWK compiled by GCC without -O2 passes its test
2281 suite using a GLR parser driven by LALR tables. It fails with -O2
2282 because `struct stat' gives two different answers on my machine:
2283 88 (definition of an auto var) and later 96 (memset on this var).
2284 Hence the stack is badly corrumpted. The headers inclusion is to
2285 blame: if I move the awk.h inclusion before GLR's system header
2286 inclusion, the two struct stat have the same size.

2397 Portability fixes for bitsets; this also avoids several GCC
2398 warnings.
2399
2400 * lib/abitset.c: Include <stddef.h>, for offsetof.
2401 * lib/lbitset.c: Likewise.
2402
2403 * lib/abitset.c (abitset_bytes): Return a size that is aligned
2404 properly for vectors of objects. Do not assume that adding a
2405 header size to a multiple of a word size yields a value that is
2406 properly aligned for the whole union.
2407 * lib/bitsetv.c (bitsetv_alloc): Likewise.
2408
2409 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
2410 unique names for structures.
2411 * lib/ebitset.c (ebitset_bytes): Likewise.
2412 * lib/lbitset.c (lbitset_bytes): Likewise.
2413
2414 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
2415 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
2416 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

2419 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
2420 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
2421 to improve the type-checking that GCC can do.
2422 * lib/bitset.c (bitset_op4_cmp): Likewise.
2423 * lib/bitset_stats.c (bitset_stats_count,
2424 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
2425 bitset_stats_copy, bitset_stats_disjoint_p,

2431 bitset_stats_andn_or_cmp, bitset_stats_or_and,
2432 bitset_stats_or_and_cmp): Likewise.
2433 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
2434 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
2435 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
2436 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
2437
2438 * lib/abitset.h: Include bitset.h, not bbitset.h.
2439 * lib/ebitset.h: Likewise.
2440 * lib/lbitset.h: Likewise.
2441
2442 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
2443 All instances of parameters of type enum bitset_opts are now of
2444 type enum_bitset_opts, to conform to the C Standard, and similarly
2445 for enum_bitset_type.
2446 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
2447 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
2448
2449 Do not use "struct bitset_struct" to mean different things in
2450 different modules. Not only is this confusing, it violates
2451 the C Standard, which requires that structure types in different
2452 modules must be compatible if one is to be passed to the other.
2453 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
2454 All instances of "struct bitset_struct *" replaced with "bitset".
2455 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
2456 (union bitset_union, struct abitset_struct, struct ebitset_struct,
2457 struct lbitset_struct, struct bitset_stats_struct): New types.
2458 All uses of struct bitset_struct changed to union bitset_union,
2459 etc.
2460 * lib/abitset.c (struct abitset_struct, abitset,
2461 struct bitset_struct): Remove.
2462 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
2463 struct bitset_struct): Remove.
2464 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
2465 bitset_struct): Remove.
2466 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
2467 Likewise.
2468
2469 Do not call a function of type T using a call that assumes the
2470 function is of a different type U. Standard C requires that a
2471 function must be called with a type that is compatible with its
2472 definition.
2473 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
2474 New decls.
2475 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
2476 New functions.
2477 * lib/ebitset.c (PFV): Remove.
2478 * lib/lbitset.c (PFV): Likewise.
2479 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
2480 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
2481 decls.
2482 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
2483 (ebitset_vtable): Use them.
2484 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
2485 lbitset_xor): New functions.
2486 (lbitset_vtable): Use them.
2487
2488 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
2489 Declare.
2490
2491 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
2492 GCC warning.
2493 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
2494 Use offsetof, for simplicity.

2514 signifies end-of-input. Warn about negative chars. Mention
2515 the portable Standard C character set.
2516
2517 The GNU coding standard says CFLAGS and YFLAGS are reserved
2518 for the installer to set.
2519 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
2520 * src/Makefile.am (AM_CFLAGS): Likewise.
2521 (AM_YFLAGS): Renamed from YFLAGS.
2522
2523 Fix some MAX and MIN problems.

4805 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
4806 full stderr, and strip it according to the bison options, instead
4807 of composing the error message from different bits.
4808 This makes it easier to check for several error messages.
4809 Adjust all the invocations.
4810 Add an invocation exercising the error token.
4811 Add an invocation demonstrating a stupid error message.
4812 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
4813 Adjust the tests.
4814 Error message are for stderr, not stdout.

4817
4818 * src/gram.h, src/gram.c (error_token_number): Remove, use
4819 errtoken->number.
4820 * src/reader.c (reader): Don't specify the user token number (2)
4821 for $undefined, as it uselessly prevents using it.
4822 * src/gram.h (token_number_t): Move to...
4823 * src/symtab.h: here.
4824 (state_t.number): Is a token_number_t.
4825 * src/print.c, src/reader.c: Use undeftoken->number instead of
4826 hard coded 2.
4827 (Even though this 2 is not the same as above: the number of the
4828 undeftoken remains being 2, it is its user token number which
4829 might not be 2).
4830 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
4831 `user_token_number_max'.
4832 Output `undef_token_number'.
4833 * data/bison.simple, data/bison.c++: Use them.
4834 Be sure to map invalid yylex return values to
4835 `undef_token_number'. This saves us from gratuitous SEGV.

4854 RITEM. Note that it must be able to code symbol numbers as
4855 positive number, and the negation of rule numbers as negative
4856 numbers.
4857 Adjust all dependencies (pretty many).
4858 * src/reduce.c (rule): Remove this `short *' pointer: use
4859 item_number_t.
4860 * src/system.h (MINSHORT, MAXSHORT): Remove.
4861 Include `limits.h'.

4869 500.

4871
4872 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
4873 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
4874 passes, but produces negative #line number, once fixed, GCC is
4875 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
4876 C), it passes.
4877 * src/state.h (state_h): Code input lines on ints, not shorts.

5694 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).

5731 problems: because Flex includes the headers *before* us,
5732 _GNU_SOURCE is not defined by config.h, and therefore strndup was
5733 not visible.

5750 Include skeleton.h.
5751 Don't use %option yylineno: it seems that then Flex imagines
5752 REJECT has been used, and therefore it won't reallocate its
5753 buffers (which makes no other sense to me than a bug). It results
5754 in warnings for `unused: yy_flex_realloc'.

6039 * src/output.c (output_gram): Rely on nritems, not the
6040 0-sentinel. See below.
6041 Use -1 as separator, not 0.
6042 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
6043 Rely on -1 as separator in yyrhs, instead of 0.
6044 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
6045 twice `Now at end of input', therefore there are two lines less to
6046 expect.

6057 is reached by eoftoken.
6058 (insert_start_shifting_state, insert_eof_shifting_state)
6059 (insert_accepting_state, augment_automaton): Remove, since now
6060 these states are automatically computed from the initial state.
6061 (generate_states): Adjust.
6062 * src/print.c: When reporting a rule number to the user, substract
6063 1, so that the axiom rule is rule 0, and the first user rule is 1.
6064 * src/reduce.c: Likewise.
6065 * src/print_graph.c (print_core): For the time being, just as for
6066 the report, depend upon --trace-flags to dump the full set of
6067 items.
6068 * src/reader.c (readgram): Once the grammar read, insert the rule
6069 0: `$axiom: START-SYMBOL $'.
6070 * tests/set.at: Adjust: rule 0 is now displayed, and since the
6071 number of the states has changed (the final state is no longer
6072 necessarily the last), catch up.

6076 Try to make the use of the eoftoken valid. Given that its value
6077 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
6078 is used instead of > 0 where appropriate, (ii), depend upon nritems
6079 instead of the 0-sentinel.

6093 reductions, then output the report anyway if requested, then die.
6094 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
6095 * src/reader.c (eoftoken): New.
6096 (parse_token_decl): If the token being defined has value `0', it
6097 is the eoftoken.
6098 (packsymbols): No longer hack `tags' to insert `$' by hand.
6099 Be sure to preserve the value of the eoftoken.
6100 (reader): Make sure eoftoken is defined.
6101 Initialize nsyms to 0: now eoftoken is created just like the others.
6102 * src/print.c (print_grammar): Don't special case the eof token.
6103 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
6104 lie anyway, albeit pleasant.
6105 * tests/calc.at: Exercise error messages with eoftoken.
6106 Change the grammar so that empty input is invalid.
6107 Adjust expectations.
6108 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

6196 (copy_action): action_line is the first line, not the last.
6197 (copy_guard): Just as for actions, store the `action' only, not
6198 the switch/case/break flesh.
6199 Don't parse the user action that might follow the guard, let...
6200 (readgram): do it, i.e., now, there can be an action after a
6201 guard.
6202 In other words the guard is just explicitly optional.

6204 * src/output.c (guards_output): New.

6244 integer when referring to a state.
6245 As much as possible, depend upon nlookaheads, instead of the
6246 `lookaheadsp' member of the following state (since lookaheads of
6247 successive states are successive, the difference between state n + 1
6248 and n served as the number of lookaheads for state n).

6947 Because useless nonterminals are now kept alive (instead of being
6948 `destroyed'), we now sometimes examine them, and store information
6949 related to them. Hence we need to know their number, and adjust
6950 memory allocations.
6951
6952 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
6953 static.
6954 * src/LR0.c (allocate_itemsets): The memory allocated to
6955 `symbol_count' was used for two different purpose: once to count
6956 the number of occurrences of each symbol, and later reassigned to
6957 `shift_symbol', containing the symbol that can be shifted from a
6958 given state.
6959 Deobfuscate, i.e., allocate, use and free `symbol_count' here
6960 only, and...
6961 (new_itemsets): Allocate `shift_symbol' here.
6962 (allocate_itemsets): symbol_count includes useless nonterminals.
6963 Make room for them.

6965 be null.

7106 an arbitrary restriction on hosts where size_t is wider than int.
7107
7108 (yyparse): Don't dump core if alloca or malloc fails; instead, report
7109 a parser stack overflow. Allocate just one block of memory for all
7110 three stacks, instead of allocating three blocks; this typically is
7111 faster and reduces fragmentation.
7112
7113 Do not limit the number of items in the stack to a value that fits

9378 Test also `--verbose', `--defines' and `--name-prefix'. Testing
9379 the latter demonstrates a flaw in the handling of non debugging
9380 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
9381 was used in order to simplify:
9382
9383 #if YYDEBUG
9384 if (yydebug)
9385 {
9386 ...
9387 }
9388 #endif
9389
9390 into
9391
9392 if (yydebug)
9393 {
9394 ...
9395 }
9396
9397 unfortunately this leads to a CPP conflict when
9398 `--name-prefix=foo' is used since it produces `#define yydebug
9399 foodebug'.

9449 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
9450 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
9451 difficult and introduced a lot of core dump. It turns out that
9452 Bison used an implementation of `xmalloc' based on `calloc', and
9453 at various places it does depend upon the initialization to 0. I
9454 have not tried to isolate the pertinent places, and all the former
9455 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
9456 someone should address this issue.

9826 Change the handling of @s so that they behave exactly like $s.
9827 There is now a pseudo variable @$ (readble and writable), location
9828 of the lhs of the rule (by default ranging from the location of
9829 the first symbol of the rhs, to the location of the last symbol,
9830 or, if the rhs is empty, YYLLOC).
9831
9832 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
9833 yyval.
9834 (yyparse): When providing a default semantic action, provide a
9835 default location action.
9836 (after the $): No longer change `*YYLSP', just stack YYLOC the
9837 same way you stack YYVAL.
9838 * src/reader.c (read_declarations): Use warns.
9839 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
9840 (copy_action, case '@'): Likewise.

9842 translators.

9865 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

9867 defined only if `YYDEBUG != 0'.

10589 always contain the token. This includes growing the token
10590 buffer while reading an integer.

10592 (parse_percent_token): Added % declarations as another
10593 way to specify the flags -n, -l, and -r. Also added hooks for
