1 2003-02-01 Paul Eggert <eggert@twinsun.com>
7 2003-01-30 Akim Demaille <akim@epita.fr>
9 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
16 Changes in response to error report by S. Eken: GLR mode does not
17 handle negative $ indices or $ indices in embedded rules correctly.
18 See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
20 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
21 (b4_rhs_location): Ditto.
22 (yyfill): New function to copy from stack tree into array
24 (yyuserAction): Modify to allow incremental move of semantic values
25 to rhs array when in GLR mode.
26 Define YYFILL to use in user-defined actions to fill semantic array
28 Remove dummy use of yystack, as there is now a guaranteed use.
29 (yydoAction): Modify to allow incremental move of semantic values
30 to rhs array when in GLR mode.
31 (yyresolveAction): Ditto.
32 (yyglrShiftDefer): Update comment.
33 (yyresolveStates): Use X == NULL for pointers, not !X.
37 * tests/glr-regr1.at: Rename to ...
38 * tests/glr-regression.at: Add new regression test for the problems
39 described above (adapted from S. Eken).
40 Update copyright notice.
41 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
42 * tests/Makefile.am: Ditto.
44 2003-01-28 Paul Eggert <eggert@twinsun.com>
46 * data/lalr1.cc: Do not use @output_header_name@ unless
47 b4_defines_flag is set. This fixes two bugs reported by
49 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
50 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
52 2003-01-21 Paul Eggert <eggert@twinsun.com>
54 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
55 we don't need to worry about yyerrlab1 being reported as an
56 "unused label" by non-GCC C compilers. The downside is that if
57 locations are used then a couple of statements are duplicated each
58 time YYERROR is invoked, but the upside is that the warnings
60 (yyerrlab1): Move code to YERROR.
61 (yyerrlab2): Remove. Change uses back to yyerrlab1.
62 This reverts some of the 2002-12-27 change.
64 2003-01-17 Paul Eggert <eggert@twinsun.com>
66 * src/output.c (symbol_printers_output): Fix typo that led
67 to core dump. Problem reported by Antonio Rus in
68 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
70 2003-01-13 Akim Demaille <akim@epita.fr>,
71 Quoc Peyrot <chojin@lrde.epita.fr>,
72 Robert Anisko <anisko_r@lrde.epita.fr>
74 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
75 when the stacks contain one element, as the loop would otherwise
76 free the last state, and then use the top state (the one we just
77 popped). This means that the initial elements will not be freed
78 explicitly, as is the case in yacc.c; it is not a problem, as
79 these elements have fake values.
81 2003-01-11 Paul Eggert <eggert@twinsun.com>
83 * NEWS: %expect-violations are now just warnings, reverting
84 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
85 bootstrapping problem reported by Matthias Klose; see
86 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
87 * src/conflicts.c (conflicts_print): Likewise.
88 * tests/conflicts.at (%expect not enough, %expect too much,
89 %expect with reduce conflicts): Likewise.
90 * doc/bison.texinfo (Expect Decl): Document this. Also mention
91 that the warning is enabled if the number of conflicts changes
92 (not necessarily increases).
94 * src/getargs.c (version): Update copyright year.
96 2003-01-09 Akim Demaille <akim@epita.fr>
98 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
100 2003-01-08 Paul Eggert <eggert@twinsun.com>
102 * Makefile.maint (WGETFLAGS):
103 New macro, containing "-C off" to disable proxy caches.
104 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
105 (rel-check): Use $(WGET) instead of wget.
107 2003-01-06 Paul Eggert <eggert@twinsun.com>
109 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
110 the GLR paper of Scott, Johnstone and Hussain.
112 2003-01-04 Paul Eggert <eggert@twinsun.com>
114 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
115 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
116 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
117 (EXTRA_LIBRARIES): New var, for liby.a.
118 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
119 (EXTRA_SCRIPTS): New var, for yacc.
121 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
122 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
123 Problem reported by Nelson H. F. Beebe.
125 2003-01-03 Paul Eggert <eggert@twinsun.com>
127 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
128 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
129 when compiling Bison 1.875's `bitset bset = obstack_alloc
130 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
132 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
133 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
134 grow to a huge size with typical invocation.
136 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
137 Use the pattern recommended by Autoconf 2.57, except also protect
138 against double-definition.
139 * src/system.h: Likewise.
140 Portability issues reported by Nelson H. F. Beebe.
142 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
143 All uses changed. Provide a definition in both C and C++.
144 (yytrue, yyfalse): Define even if defined (__cplusplus).
146 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
147 Reported by Nelson H. F. Beebe.
149 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
151 2003-01-02 Paul Eggert <eggert@twinsun.com>
153 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
154 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
155 Bug reported by Nelson H. F. Beebe.
157 2003-01-01 Paul Eggert <eggert@twinsun.com>
161 2002-12-30 Paul Eggert <eggert@twinsun.com>
163 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
165 (<INITIAL>","): Here. This causes stray "," to be treated
168 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
169 last brace in braced code when not in Yacc mode, for compatibility
170 with Bison 1.35. This resurrects the 2001-12-15 patch to
173 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
174 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
176 2002-12-28 Paul Eggert <eggert@twinsun.com>
178 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
179 that of SYM's type. This fixes Debian bug 168069, reported by
182 2002-12-28 Paul Eggert <eggert@twinsun.com>
186 Switch back to the Yacc style of conflict reports, undoing some
187 of the 2002-07-30 change.
188 * doc/bison.texinfo (Understanding): Use Yacc style for
189 conflict reports. Also, use new way of locating rules.
190 * src/conflicts.c (conflict_report):
191 Renamed from conflict_report_yacc, removing the old
192 'conflict_report'. Translate the entire conflict report at once,
193 so that we don't assume that "," has the same interpretation in
195 (conflicts_output): Use Yacc-style conflict report for each state,
196 instead of our more-complicated style.
197 (conflicts_print): Use Yacc-style conflict report, except print
198 the input file name when not emulating Yacc.
199 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
200 Conflicted Reduction, %expect not enough, %expect too much,
201 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
202 * tests/existing.at (GNU Cim Grammar): Likewise.
203 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
205 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
206 fatal): Don't invoke fflush; it's not needed and it might even be
207 harmful for stdout, as stdout might not be open.
208 * src/reduce.c (reduce_print): Likewise.
210 2002-12-27 Paul Eggert <eggert@twinsun.com>
212 Fix a bug where error locations were not being recorded correctly.
213 This problem was originally reported by Paul Hilfinger in
214 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
216 * data/yacc.c (yyparse): New local var yylerrsp, to record the
217 top of the location stack's error locations.
218 (yyerrlab): Set it. When discarding a token, push its location
219 onto yylerrsp so that we don't lose track of the error's end.
220 (yyerrlab1): Now is only the target of YYERROR, so that we can
221 properly record the location of the action that failed. For GCC
222 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
223 GCC warning about yyerrlab1 being unused if YYERROR is unused.
224 (yyerrlab2): New label, which yyerrlab now falls through to.
225 Compute the error's location by applying YYLLOC_DEFAULT to
226 the locations of all the symbols that went into the error.
227 * doc/bison.texinfo (Location Default Action): Mention that
228 YYLLOC_DEFAULT is also invoked for syntax errors.
229 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
230 Error locations include the locations of all the tokens that were
231 discarded, not just the last token.
233 2002-12-26 Paul Eggert <eggert@twinsun.com>
235 * src/files.c: Include quote.h.
236 (compute_output_file_names): Warn if we detect conflicting
237 outputs to the same file. This should catch the misunderstanding
238 exemplified by Debian Bug 165349, reported by Bruce Stephens..
240 * src/conflicts.c (conflicts_print): If the user specifies
241 "%expect N", report an error if there are any reduce/reduce
242 conflicts. This is what the manual says should happen.
243 This fixes Debian bug 130890, reported by Anthony DeRobertis.
244 * tests/conflicts.at (%expect with reduce conflicts): New test.
246 Don't use m4_include on relative file names, as it doesn't work as
247 desired if there happens to be a file with that name under ".".
249 * m4sugar/version.m4: Remove; it was included but it wasn't used.
250 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
251 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
252 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
253 * src/output.c (output_skeleton): Use full path names when
254 specifying a file to include; don't rely on include path, as
255 it's unreliable when the working file contains a file with
258 2002-12-25 Paul Eggert <eggert@twinsun.com>
260 Remove obsolete references to bison.simple and bison.hairy.
261 Problem mentioned by Aubin Mahe in
262 <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
263 * data/glr.c: Comment fix.
264 * doc/bison.1: Remove references. Also, mention "yacc".
266 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
269 * src/parse-gram.y (declaration): Use enum "report_states" rather
270 than its numeric value 1.
272 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
273 opening a new one. This fixes Debian bug 165349, reported by
276 2002-12-24 Paul Eggert <eggert@twinsun.com>
280 * Makefile.maint (cvs-update): Don't assume that the shell
281 supports $(...), as Solaris sh doesn't.
283 * src/parse-gram.y (lloc_default): Remove test for empty
284 nonterminals at the end, since it didn't change the result.
286 2002-12-24 Paul Eggert <eggert@twinsun.com>
288 If the user does not define YYSTYPE as a macro, Bison now declares it
289 using typedef instead of defining it as a macro. POSIX requires this.
290 For consistency, YYLTYPE is also declared instead of defined.
292 %union directives can now have a tag before the `{', e.g., the
293 directive `%union foo {...}' now generates the C code
294 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
295 The default union tag is `YYSTYPE', for compatibility with Solaris 9
296 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
297 instead of `yyltype'.
299 `yystype' and `yyltype' are now obsolescent macros instead of being
300 typedefs or tags; they are no longer documented and will be
301 withdrawn in a future release.
303 * data/glr.c (b4_location_type): Remove.
304 (YYSTYPE): Renamed from yystype.
305 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
306 (struct YYLTYPE): Renamed from struct yyltype.
307 (YYLTYPE): Renamed from yyltype.
308 (yyltype, yystype): New (and obsolescent) macros,
309 for backward compatibility.
310 * data/yacc.c: Likewise.
312 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
313 does not specify a union tag. This is for compatibility with
316 * src/parse-gram.y (add_param): 2nd arg is now char * not char
317 const *, since it is now modified by stripping surrounding { }.
318 (current_braced_code): Remove.
319 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
320 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
321 trailing " {...}". Now of type <chars>.
322 (grammar_declaration): Adjust to bundled tokens.
323 (code_content): Remove; stripping is now done by add_param.
324 (print_token_value): Print contents of bundled tokens.
325 (token_name): New function.
327 * src/reader.h (braced_code, current_braced_code): Remove.
328 (token_name): New decl.
330 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
331 token_type, not braced_code code_kind. All uses changed.
332 (SC_PRE_CODE): New state, for scanning after a keyword that
333 has (or usually has) an immediately-following braced code.
334 (token_type): New local var, to keep track of which token type
335 to return when scanning braced code.
336 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
337 <INITIAL>"%parse-param", <INITIAL>"%printer",
338 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
339 instead of returning a token type immediately.
340 (<INITIAL>"{"): Set token type.
341 (<SC_BRACED_CODE>"}"): Use it.
342 (handle_action_dollar, handle_action_at): Now returns bool
343 indicating success. Fail if ! current_rule; this prevents a core dump.
344 (handle_symbol_code_dollar, handle_symbol_code_at):
345 Remove; merge body into caller.
346 (handle_dollar, handle_at): Complain in invalid contexts.
348 * NEWS, doc/bison.texinfo: Document the above.
349 * NEWS: Fix years and program names in copyright notice.
351 2002-12-17 Paul Eggert <eggert@twinsun.com>
353 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
354 Reporting, Table of Symbols): Omit mentions of %lex-param and
355 %parse-param from the documentation for now.
357 2002-12-15 Paul Eggert <eggert@twinsun.com>
359 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
360 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
361 lookahead symbol, and which sets yychar in parser actions) and it
362 disagreed with the Bison documentation. Bug
363 reported by Andrew Walrond.
365 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
366 as the caller now does that.
367 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
368 (YYEMPTY): Parenthesize right hand side, since others use it.
369 (yyparse): Don't assume that our generated code is the only code
372 2002-12-13 Paul Eggert <eggert@twinsun.com>
376 POSIX requires a "yacc" command.
377 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
378 (MOSTLYCLEANFILES): Add yacc.
380 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
381 as an alias for bison y.
383 * po/LINGUAS: Add da.
385 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
386 problem with latest <getopt.h>.
387 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
389 * doc/fdl.texi: Upgrade to 1.2.
390 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
391 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
392 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
394 * config/install-sh: Sync with autotools.
396 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
397 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
398 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
399 locations are requested.
400 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
401 locations are requested.
403 2002-12-12 Paul Eggert <eggert@twinsun.com>
405 Remove unportable casts and storage allocation tricks.
406 While we're at it, remove almost all casts, since they
407 usually aren't needed and are a sign of trouble.
409 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
411 * src/derives.c (derives_compute): Do not subtract NTOKENS from
412 the pointer DSET returned by malloc; this isn't portable.
413 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
414 Similarly for DERIVES.
415 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
416 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
417 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
419 * src/derives.c (derives_compute): Do not bother invoking
420 int_of_rule_number, since rule numbers are integers.
422 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
423 rather than XMALLOC (char, N).
425 * src/files.c (filename_split): Rewrite to avoid cast.
427 * src/gram.h (symbol_number_as_item_number,
428 item_number_as_symbol_number, rule_number_as_item_number,
429 item_number_as_rule_number):
430 Now inline functions rather than macros, to avoid casts.
431 * src/state.h (state_number_as_int): Likewise.
432 * src/tables.c (state_number_to_vector_number,
433 symbol_number_to_vector_number): Likewise.
435 * src/gram.h (int_of_rule_number): Remove; no longer used.
437 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
438 since the resulting storage is always stored into.
440 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
443 * src/muscle_tab.c (muscle_m4_output):
444 Now inline. Return bool, not int.
445 * src/state.c (state_compare): Likewise.
446 * src/symtab.c (symbol_check_defined,
447 symbol_check_alias_consistency, symbol_pack, symbol_translation,
448 hash_compare_symbol, hash_symbol):
450 * src/uniqstr.c (uniqstr_print): Likewise.
451 * src/muscle_tab.c (muscle_m4_output_processor):
452 New function, to avoid casts.
453 * src/state.c (state_comparator, stage_hasher): Likewise.
454 * src/symtab.c (symbol_check_defined_processor,
455 symbol_check_alias_consistency_processor, symbol_pack_processor,
456 symbol_translation_processor, hash_symbol_comparator,
457 hash_symbol_hasher): Likewise.
458 * src/uniqstr.c (uniqstr_print_processor): Likewise.
459 * src/muscle_tab.c (muscles_m4_output):
460 Use new functions instead of casting old functions unportably.
461 * src/state.c (state_hash_new): Likewise.
462 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
463 symbols_token_translations_init):
465 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
467 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
468 var instead of casting to long, to avoid casts.
469 (prepare_states): Use MALLOC rather than alloca, so that we don't
470 have to worry about alloca.
471 * src/state.c (state_hash_lookup): Likewise.
473 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
474 local var instead of casting to unsigned char, to avoid casts.
476 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
477 STATE_ALLOC): Remove.
478 (transitions_new, errs_new, reductions_new, state_new): Use malloc
479 rather than calloc, and use offsetof to avoid allocating slightly
481 (state_new): Initialize all members.
483 * src/state.c (state_hash): Use unsigned accumulator, not signed.
485 * src/symtab.c (symbol_free): Remove; unused.
486 (symbol_get): Remove cast in lhs of assignment.
487 (symbols_do): Now static. Accept generic arguments, not
488 hashing-related ones.
490 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
491 (symbol_processor): Remove.
492 (symbols_do): Remove decl; now static.
494 * src/system.h (alloca): Remove; decl no longer needed.
495 (<stddef.h>): Include, for offsetof.
496 (<inttypes.>, <stdint.h>): Include if available.
497 (uintptr_t): New type, if system lacks it.
498 (CALLOC, MALLOC, REALLOC): New macros.
499 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
502 * src/tables.c (table_size): Now int, to pacify GCC.
503 (table_grow, table_ninf_remap): Use signed table size.
504 (save_row): Don't bother initializing locals when not needed.
505 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
506 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
508 * src/vcg.h: Correct misspellings.

513 * src/getargs.c (getargs): Don't assume EOF == -1.
515 2002-12-09 Paul Eggert <eggert@twinsun.com>
517 Change identifier spellings to avoid collisions with names
518 that are reserved by POSIX.
520 Don't use names ending in _t, since POSIX reserves them.
521 For consistency, remove _e and _s endings -- they're weren't
522 needed to remove ambiguity. All uses changed.
523 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
524 turn was just renamed from struniq_t.
525 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
526 which in turn was just renamed from struniq_processor_t.

597 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
598 value_t_as_yystype -> value_as_yystype.
600 Don't include <errno.h> in the mainstream code, since it
601 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
602 * lib/get-errno.c, lib/get-errno.h: New files.
603 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
605 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
606 * src/output.c (output_skeleton): Likewise.
607 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
609 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):

613 (TAB_EXT): Renamed from EXT_TAB.
614 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
616 Avoid str[a-z]*, since <string.h> reserves that name space.

618 likewise for "STRUNIQ" and "UNIQSTR".
619 * src/uniqstr.c: Renamed from src/struniq.c.
620 * src/uniqstr.h: Renamed from src/struniq.h.
621 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

651 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
655 * lib/timevar.c (timevar_report): Renamed from time_report,
656 for consistency with other names.
657 * lib/timevar.h (timevar_report): New decl.
658 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
661 Sort include-file uses.
663 Reorder all include files under src to be in the order "system.h".
664 then the ../lib include files in angle brackets (alphabetized),
665 then the . include files in double-quotes (alphabetized). Fix
666 dependency breakages encountered in this process, as follows:
667 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
668 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
669 * src/state.h: Include "symtab.h".
671 2002-12-08 Paul Eggert <eggert@twinsun.com>
673 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
674 since this causes problems when __file__ contains character
675 sequences like "@" that are treated specially by src/scan-skel.l.
676 Instead, just use the file's basename. This fixes the bug
677 reported by Martin Mokrejs in
678 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
680 2002-12-06 Paul Eggert <eggert@twinsun.com>
682 Add support for rules that do not have trailing semicolons, as
683 POSIX requires. Improve the quality of locations in Bison
686 * src/location.c: Include <quotearg.h>.
687 (empty_location): Now const.
688 (location_print): New function. Follow the recommendation of the
689 GNU Coding Standards for locations that span file boundaries.
690 * src/location.h: Do not include <quotearg.h>; no longer needed.
691 (boundary): New type.
692 (location_t): Use it. This allows locations to span file boundaries.
693 All member uses changed: file -> start.file or end.file (as needed),
694 first_line -> start.line, first_column -> start.column,
695 last_line -> end.line, last_column -> end.column.
696 (equal_boundaries): New function.
697 (LOCATION_RESET, LOCATION_STEP): Remove.
698 (LOCATION_PRINT): Remove. All callers changed to use location_print.
699 (empty_location): Now const.
700 (location_print): New decl.
701 * src/parse-gram.y (lloc_default): New function, which handles
702 empty locations more accurately.

704 (%token COLON): Remove.
705 (%token ID_COLON): New token.
707 (declarations, rules): Remove trailing semicolon.
708 (declaration, rules_or_grammar_declaration):
709 Allow empty (";") declaration.
710 (symbol_def): Remove empty actions; no longer needed.
711 (rules_or_grammar_declaration): Remove trailing semicolon.
712 (semi_colon.opt): Remove.
713 * src/reader.h: Include location.h.
714 (scanner_cursor): New decl.
715 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
717 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
719 (STEP): Remove. No longer needed, now that adjust_location does
720 the work. All uses removed.
721 (scanner_cursor): New var.
722 (adjust_location): Renamed from extend_location. It now sets
723 *loc and adjusts the scanner cursor. All uses changed.
724 Don't bother testing for CR.
725 (handle_syncline): Remove location arg; now updates scanner cursor.
727 (unexpected_end_of_file): Now accepts start boundary of token or
728 comment, not location. All callers changed. Update scanner cursor,
730 (SC_AFTER_IDENTIFIER): New state.
731 (context_state): Renamed from c_context. All uses changed.
732 (id_loc, code_start, token_start): New local vars.
733 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
734 processing of Yacc white space and equivalents here.
735 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
736 instead of returning ID immediately, since we need to search for
738 (<INITIAL>"'", "\""): Save token_start.
739 (<INITIAL>"%{", "{", "%%"): Save code_start.
740 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
741 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
742 BEGIN context_state at end, not INITIAL.
743 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
744 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
745 Return correct token start.
746 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
747 the start of a character, string or multiline comment is found.
748 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
749 Reduction): Adjust reported locations to match the more-precise
750 results now expected.
751 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
752 * tests/reduce.at (Useless Rules, Reduced Automaton,
753 Underivable Rules): Likewise.
754 * tests/regression.at (Invalid inputs): No longer `expecting ";"
755 or "|"' now that so many other tokens are allowed by the new grammar.
757 * src/complain.h (current_file): Remove duplicate decl;
758 current_file is now owned by files.h.
759 * src/complain.c, src/scan-gram.l: Include files.h.
761 2002-12-06 Paul Eggert <eggert@twinsun.com>
763 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
764 promotes to int; it might be unsigned int.
765 * data/yacc.c (yy_reduce_print): Likewise.
767 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
768 be #defined in the prologue, not in the Bison declarations.
769 This fixes Debian Bug 102878, reported by Shaul Karl.
771 2002-12-02 Paul Eggert <eggert@twinsun.com>
773 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
774 * lib/strtoul.c: New file, from gnulib.
775 This fixes a porting bug reported by Peter Klein in
776 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
778 2002-11-30 Paul Eggert <eggert@twinsun.com>
780 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
781 and put only a forward declaration in the prologue. This is for
782 consistency with the other scanner helper functions.
784 Type clashes now generate warnings, not errors, since it
785 appears that POSIX may allow some grammars with type clashes.
786 * src/reader.c (grammar_current_rule_check): Warn about
787 type clashes instead of complaining.
788 * tests/input.at (Type Clashes): Expect warnings, not complaints.
790 Add Yacc library, since POSIX requires it.
791 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
792 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
793 * lib/main.c, lib/yyerror.c: New files.
795 gram_error can be static; it need not be extern.
796 * src/reader.h (gram_error): Remove decl.
797 * src/parse-gram.y (gram_error): Now static. Add static decl.
798 (print_token_value): Omit parameter names from forward decl,
801 2002-11-29 Paul Eggert <eggert@twinsun.com>
803 * doc/bison.texinfo: Emphasize that yylex and yyerror must
804 be declared before being used. E.g., one should typically
805 declare them in the prologue. Use GNU coding style in examples.
806 Put "const" consistently after the type it modifies. Mention
807 that C99 supports "inline". Mention that yyerror traditionally
810 %parse-param and %lex-param now take just one argument, the
811 declaration; the argument name is deduced from the declaration.
813 * doc/bison.texinfo (Parser Function, Pure Calling, Error
814 Reporting, Table of Symbols): Document this.
815 * src/parse-gram.y (add_param): New function.
817 (declaration): Implement new rule for %parse-param and %lex-param.
818 * src/scan-gram.l: "," now elicits a warning, rather than being
819 a token; this is more compatible with byacc.
820 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
822 2002-11-27 Paul Eggert <eggert@twinsun.com>
824 Rename identifiers to avoid real and potential collisions.
826 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
827 to avoid collision with lex macro described by Bruce Lilly in
828 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
829 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
830 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
831 * src/parse-gram.y (print_token_value): Renamed from yyprint.
833 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
834 The name "yycontrol" violates the name space rules, and this stuff
835 wasn't being used anyway.
836 (input): Remove action; this stuff wasn't being used.
837 (gram_error): Rename local variable yylloc -> loc.
838 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
839 (YY_DECL): Don't use "yy" at start of local variables.
840 All uses changed, e.g., yylloc -> loc.
841 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
842 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
843 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
844 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
846 * src/parse-gram.y (gram_error): loc is now const *.
847 * src/reader.h (gram_error): Likewise.
849 2002-11-24 Paul Eggert <eggert@twinsun.com>
853 * tests/actions.at (Actions after errors): Use an output format
854 more similar to that of the Printers and Destructors test.
855 Test the position of the ';' token too.
856 (Printers and Destructors): Likewise.
857 (Printers and Destructors: %glr-parser): Remove for now, to avoid
858 unnecessarily alarming people when the test fails.
860 * data/yacc.c (yyerrlab1): Move this label down, so that the
861 parser does not discard the lookahead token if the user code
862 invokes YYERROR. This change is required for POSIX conformance.
864 * lib/error.c: Sync with gnulib.
866 2002-11-22 Paul Eggert <eggert@twinsun.com>
868 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
869 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
870 * lib/xmalloc.c: Likewise.
872 2002-11-20 Paul Eggert <eggert@twinsun.com>
874 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
876 2002-11-20 Paul Eggert <eggert@twinsun.com>
878 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
879 should use `if (! x) abort ();' rather than `assert (x);', and
880 anyway it's one less thing to worry about configuring.
882 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
883 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
884 and replace all instances of assert with abort.
885 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
886 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
888 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
889 yyresolveAction, yyprocessOneStack): Use abort rather than assert.

891 hash_find_entry, hash_rehash, hash_insert): Likewise.
892 * src/conflicts.c (resolve_sr_conflict): Likewise.
893 * src/lalr.c (set_goto_map, map_goto): Likewise.
894 * src/nullable.c (nullable_compute): Likewise.
895 * src/output.c (prepare_rules, token_definitions_output): Likewise.
896 * src/reader.c (packgram, reader): Likewise.
897 * src/state.c (state_new, state_free, state_transitions_set,
898 state_reduction_find): Likewise.
899 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
900 symbol_pack): Likewise.
901 * src/tables.c (conflict_row, pack_vector): Likewise.
902 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,

904 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
905 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
907 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
908 (ARGMATCH_CONSTRAINT): New macro.
909 (ARGMATCH_ASSERT): Use it.
911 * src/system.h (verify): New macro.
912 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
914 * src/tables.c (tables_generate): Likewise.
916 * src/struniq.c (struniq_assert): Now returns void, and aborts
917 if the assertion is false.
918 (struniq_assert_p): Remove.
919 * src/struniq.h: Likewise.
921 2002-11-18 Paul Eggert <eggert@twinsun.com>
923 * data/glr.c (yygetLRActions): Replace `yyindex' with
924 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
925 This fixes the regression with Sun ONE Studio 7 cc that I reported in
926 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
928 2002-11-18 Akim Demaille <akim@epita.fr>
930 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
934 2002-11-17 Paul Eggert <eggert@twinsun.com>
936 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
937 to "SyntaxError" for consistency with my 2002-11-15 change.
939 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
940 not define to {}, since this breaks the common use of `YYDPRINTF
941 ((...));' if a single statement is desired (e.g. before `else').
942 Work around GCC warnings by surrounding corresponding calls with
944 (yyhasResolvedValue): Remove unused function.
945 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
947 (yyreportSyntaxError): Renamed from yyreportParseError.
948 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
950 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
951 extern when possible. Remove unused initializations.
953 2002-11-16 Akim Demaille <akim@epita.fr>
955 Augment the similarity between GLR and LALR traces.
957 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
958 (YY_REDUCE_PRINT): New.
960 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
962 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
963 state reached after the reduction/recovery, since...
964 (yyparse, yyprocessOneStack): Report the state we are entering in.
966 2002-11-16 Akim Demaille <akim@epita.fr>
968 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
969 Add support for --trace=skeleton.
970 * src/scan-skel.l: %option debug.

974 (@output_parser_name@, @output_header_name@): ``Restore'' their
975 support (used to be M4 macros).
976 * data/yacc.c: Quote larger chunks, a la glr.c.
977 * data/lalr1.cc: Likewise.
978 The header guards are no longer available, so use some other
979 string than `YYLSP_NEEDED'.
981 2002-11-16 Akim Demaille <akim@epita.fr>
983 Make the ``Printers and Destructors'' test more verbose, taking
984 `yacc.c''s behavior as (possibly wrong) reference.
986 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
987 instead of fprint on stdout.
988 Set and report the last_line of the symbols.
989 Consistently display values and locations.
991 2002-11-16 Paul Eggert <eggert@twinsun.com>
993 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
995 2002-11-15 Paul Eggert <eggert@twinsun.com>
997 * tests/actions.at (Actions after errors): New test case.
999 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
1000 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
1001 tests/action.at, tests/calc.at, tests/conflicts.at,
1002 tests/cxx-type.at, tests/regression.at:
1003 "parse error" -> "syntax error" for POSIX compatibility.
1004 "parsing stack overflow..." -> "parser stack overflow" so
1005 that code matches Bison documentation.
1007 2002-11-15 Akim Demaille <akim@epita.fr>
1009 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
1010 take two BRACED_CODE, not two string_content.
1011 Free the scanner's obstack when we are done.
1012 (code_content): New.
1013 * tests/calc.at: Adjust.
1014 * doc/bison.texinfo: Adjust.
1015 Also, make sure to include the `,' for these declarations.
1017 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
1019 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
1020 definition; avoids potential autoreconf problems.
1022 2002-11-15 Akim Demaille <akim@epita.fr>
1024 Always check the value returned by yyparse.
1026 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
1027 returned by yyparse.
1028 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
1030 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
1031 returned by yyparse.
1033 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1035 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
1038 2002-11-14 Paul Eggert <eggert@twinsun.com>
1040 * src/output.c (output_skeleton): Call xfopen instead of
1041 duplicating xfopen's body.
1043 Fix bugs reported by Nelson H. F. Beebe in
1044 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
1046 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
1047 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
1048 Group compiler. Instead, use "$CC -E bar.c". Include the .h
1049 file twice in the grammar, as an extra check.
1051 * tests/input.at (Torturing the Scanner): Surround the
1052 backslash-newline tests with "#if 0", to make it less likely that
1053 we'll run into compiler bugs. Bring back solitary \ inside
1054 comment, but add a closing comment to work around HP C bug. Don't
1055 test backslash-newline in C character constant.
1057 2002-11-14 Akim Demaille <akim@epita.fr>
1059 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
1060 status of the compiler.
1061 Calling `exit 1' is no longer needed.
1062 Reported by Nelson H. F. Beebe.

1072 grammars that are to be compiled.
1073 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
1074 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
1075 * doc/bison.texinfo (GLR Parsers): Document `inline'.
1077 2002-11-14 Akim Demaille <akim@epita.fr>
1079 * doc/bison.texinfo: Various formatting changes (alignments in
1080 samples, additional @group/@end group, GCS in samples.
1081 Use @deffn instead of simple @table to define the directives,
1082 macros, variables etc.
1084 2002-11-13 Paul Eggert <eggert@twinsun.com>
1086 Fix some bugs reported by Albert Chin-A-Young in
1087 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
1089 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
1090 -o c"; the HP C compiler chatters during compilation.
1091 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
1092 * tests/headers.at (export YYLTYPE): Likewise.
1094 * tests/input.at (Torturing the Scanner): Remove lines containing
1095 solitary backslashes, as they tickle a bug in the HP C compiler.
1097 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
1098 comments, since they're not portable. Use GNU coding style.
1100 2002-11-13 Akim Demaille <akim@epita.fr>
1102 * data/yacc.c: Leave bigger chunks of quoted text.
1103 (YYDSYMPRINTF): New.
1104 Use it to report symbol activities.
1105 * data/glr.c (YYDSYMPRINTF): New.
1108 2002-11-12 Paul Eggert <eggert@twinsun.com>
1112 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
1113 (yyglrReduce): Return yyok, not 0.
1114 This should avoid the enumerated-type warnings reported
1115 by Nelson H. F. Beebe in
1116 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
1118 * lib/bbitset.h (BITSET_INLINE): Remove.
1119 * lib/bitset.h [! BITSET_INLINE]: Remove.
1120 (bitset_set, bitset_reset, bitset_test): Rename local vars
1121 to avoid shadowing warnings by GCC.
1123 * data/glr.c (inline): Remove #define. It's the user's
1124 responsibility to #define it away, just like 'const'.
1125 This fixes one of the bugs reported by Nelson H. F. Beebe in
1126 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
1128 * Makefile.maint (po-check): Scan .l and .y files instead of the
1129 .c and the .h files that they generate. This fixes the bug
1130 reported by Tim Van Holder in:
1131 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
1132 Look for N_ as well as for _. Try to avoid matching #define for
1134 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
1135 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
1136 * src/scan-gram.l: Revamp regular expressions so that " and '
1137 do not confuse xgettext.
1139 * src/struniq.h (struniq_new): Do not declare the return type
1140 to be 'const'; this violates the C standard.
1141 * src/struniq.c (struniq_new): Likewise.
1143 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
1145 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
1146 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
1149 2002-11-12 Akim Demaille <akim@epita.fr>
1151 * Makefile.maint: Sync with Autoconf:

1168 2002-11-12 Akim Demaille <akim@epita.fr>
1170 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
1171 Use it to test the GLR parser.
1173 2002-11-12 Akim Demaille <akim@epita.fr>
1175 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
1177 * data/glr.c (yystos): New.
1178 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
1180 (yyval): Don't define it, it is handled via M4.
1181 (yyrecoverParseError): Free verbosely the discarded symbols.
1182 * data/yacc.c (yysymprint): Remove, rather...
1183 (b4_yysymprint_generate): invoke.
1184 * data/c.m4 (b4_yysymprint_generate): New.
1185 Accept pointers as arguments, as opposed to the version from
1187 (b4_yydestruct_generate): Likewise.
1188 * tests/cations.at (Printers and Destructors): Use Bison directives
1189 instead of CPP macros.
1190 Don't rely on internal details.
1192 2002-11-12 Akim Demaille <akim@epita.fr>
1194 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
1195 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
1196 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
1197 it against YYEMPTY and so forth), work on yytoken (i.e., set
1198 it to YYEMPTY etc.).
1199 (yydestruct): Replace with a b4_yydestruct_generate invocation.
1200 (b4_symbol_actions): Remove.
1201 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
1202 for 0, end-of-input.
1204 2002-11-12 Akim Demaille <akim@epita.fr>
1206 * doc/bison.texinfo (Destructor Decl): New.
1208 2002-11-12 Akim Demaille <akim@epita.fr>
1210 * src/tables.c (tables_generate): Use free for pointers that
1211 cannot be NULL, not XFREE.

1213 * src/state.c (state_new): Likewise.
1214 * src/reader.c (reader): Likewise.
1215 * src/lalr.c (set_goto_map): Likewise.
1216 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
1219 2002-11-12 Akim Demaille <akim@epita.fr>
1221 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
1223 * src/scan-gram.l (last_string): Is global to the file, not to
1225 * src/parse-gram.y (input): Don't append the epilogue here,
1226 (epilogue.opt): do it here, and free the scanner's obstack.
1227 * src/reader.c (epilogue_set): Rename as...
1228 (epilogue_augment): this.
1229 * data/c.m4 (b4_epilogue): Defaults to empty.
1231 2002-11-12 Akim Demaille <akim@epita.fr>
1233 * src/getargs.c (long_options): Remove duplicates.

1287 2002-11-11 Paul Eggert <eggert@twinsun.com>
1289 Revamp to fix many (but not all) of the C- and M4-related quoting
1290 problems. Among other things, this fixes the Bison bug reported
1291 by Jan Hubicka when processing the Bash grammar; see:
1292 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
1294 Use new @ escapes consistently. Represent brackets with @{ and @}
1295 rather than @<:@ and @:>@, since this works a bit better with dumb
1296 editors like vi. Represent @ with @@, since @ is now consistently
1297 an escape. Use @oline@ and @ofile@ rather than __oline__ and
1298 __ofile__, to avoid unexpected expansions. Similarly, use @output
1299 rather than #output.
1301 * data/c.m4 (b4_copyright): Omit file name from comment, since
1302 the file name could contain "*/".
1303 (b4_synclines_flag): Don't quote the 2nd argument; it should already
1304 be quoted. All uses changed.
1306 * data/glr.c: Use new @ escapes consistently.
1307 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
1308 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
1309 Remove, since they couldn't handle arbitrary characters in file
1311 * data/lalr1.cc: Likewise.
1312 * data/yacc.c: Likewise.
1314 * src/files.c (output_infix): Remove; all uses removed.
1315 * src/files.h: Likewise.
1317 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
1318 mishandled funny characters in file names, and anyway it isn't
1320 * data/yacc.c: Likewise.
1321 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
1323 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
1324 * data/yacc.c: Likewise.
1326 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
1328 (muscle_init): Quote filename as a C string.
1329 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
1330 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
1331 * src/output.c (escaped_file_name_output): New function.
1332 (prepare_symbols): Quote tokens for M4.
1333 (prepare): Don't insert output_infix, output_prefix,
1334 output_parser_name, output_header_name; this is now down by scan-skel.
1335 Insert skeleton as a C string.
1337 * src/output.c (user_actions_output, symbol_destructors_output,
1338 symbol_printers_output): Quote filenames for C and M4.
1339 * src/reader.c (prologue_augment, epilogue_set): Likewise.
1341 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
1342 escapes other than \\ and \'; this simplifies the code.
1343 (<SC_STRING>): Likewise, for \\ and \".
1344 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
1345 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
1346 Use new escapes @{ and @} for [ and ].
1348 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
1349 them with auto vars.
1350 Switch to new escape scheme, where @ is the escape character uniformly.
1351 Abort if a stray escape character is found. Avoid unbounded input
1352 buffer when parsing non-escaped text.
1354 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
1355 __oline__, #output, $@, and @{ do not have unintended meanings.
1357 2002-11-09 Paul Eggert <eggert@twinsun.com>
1359 Fix the test failure due to GCC warnings described in
1360 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
1361 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
1362 evaluate to 0 if it's impossible for NINF to be in the respective
1364 (yygetLRActions, yyrecoverParseError): Use them.
1366 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
1367 counted in the token inserted at end of file. Now takes
1368 location_t *, not location_t, so that the location can be
1369 adjusted. All uses changed.
1371 * tests/regression.at (Invalid inputs): Adjust wording in
1372 diagnostic to match the new behavior.
1374 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
1375 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
1376 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
1377 abort ();'. This reduces the runtime of the "Many lookaheads"
1378 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
1381 2002-11-07 Paul Eggert <eggert@twinsun.com>
1383 * src/parse-gram.y (CHARACTER): Remove unused token.
1386 * src/scan-gram.l: Remove stack option. We no longer use the
1387 stack, since the stack was never deeper than 1; instead, use the
1388 new auto var c_context to record the stacked value.
1390 Remove nounput option. At an unexpected end of file, we now unput
1391 the minimal input necessary to end cleanly; this simplifies the
1394 Avoid unbounded token sizes where this is easy.
1396 (unexpected_end_of_file): New function.
1397 Use it to systematize the error message on unexpected EOF.
1398 (last-string): Now auto, not static.
1399 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
1400 (scanner_last_string_free): Remove; not used.
1401 (percent_percent_count): Move decl to just before use.
1402 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
1403 not the (never otherwised-used) CHARACTER.
1405 2002-11-07 Akim Demaille <akim@epita.fr>
1407 Let yyerror always receive the msg as last argument, so that
1408 yyerror can be variadic.
1410 * data/yacc.c (b4_yyerror_args): New.
1411 Use it when calling yyerror.
1412 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
1413 Use it when calling yyerror.
1414 * doc/bison.texinfo (Error Reporting): Adjust.

1418 2002-11-06 Akim Demaille <akim@epita.fr>
1420 #line should have quoted strings.
1421 Ideally, this should be done by m4_quotearg.
1423 * src/scan-skel.l: Include quotearg.h.
1425 * src/output.c (symbol_printers_output)
1426 (symbol_destructors_output): Quote the file name.
1428 2002-11-06 Akim Demaille <akim@epita.fr>

1439 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
1440 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
1441 * src/output.c (user_actions_output): Likewise.
1442 (prepare): Define 'b4_synclines_flag'.
1443 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
1445 2002-11-06 Akim Demaille <akim@epita.fr>
1447 * src/main.c (main): Free `infile'.
1448 * src/scan-gram.l (handle_syncline): New.
1450 * src/output.c (user_actions_output, symbol_destructors_output)
1451 (symbol_printers_output): Use the location's file name, not
1453 * src/reader.c (prologue_augment, epilogue_set): Likewise.
1455 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1457 * src/tables.c (matching_state): Don't allow states to match if
1458 either has GLR conflict entries.
1460 2002-11-05 Paul Eggert <eggert@twinsun.com>
1462 * src/scan-gram.l: Use more accurate diagnostics, e.g.
1463 "integer out of range" rather than "invalid value".
1464 * tests/input.at (Invalid $n, Invalid @n): Change expected wording

1474 as POSIX 1003.1-2001 requires.
1475 * src/system.h (IF_LINT): New macro, taken from coreutils.
1476 * configure.ac: Define "lint" if --enable-gcc-warnings.
1478 2002-11-05 Akim Demaille <akim@epita.fr>
1480 * src/scan-gram.l: When it starts with `%', complain about the

1497 2002-11-04 Akim Demaille <akim@epita.fr>
1499 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
1501 * src/scan-gram.l: Use [\'] instead of ['] to pacify
1504 Use quote, not quote_n since LOCATION_PRINT no longer uses the
1507 2002-11-03 Paul Eggert <eggert@twinsun.com>
1509 * src/reader.c (get_merge_function, grammar_current_rule_check):
1510 Use consistent diagnostics for reporting type name clashes.

1525 Use b4_identification.
1526 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
1527 b4_user_formals and b4_user_args.
1528 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
1529 (yyreportAmbiguity): When using a pure parser, also need
1530 the location, and the parse-params.
1532 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
1533 When using a pure parser, also need the parse-params.
1535 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
1536 (%pure-parser + %parse-param) LALR and GLR parsers.
1537 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
1538 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

1551 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
1552 AT_CHECK_CALC_GLR invocations to use % directives, instead of
1553 command line options.

1556 2002-11-03 Paul Eggert <eggert@twinsun.com>
1558 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
1559 to count columns correctly, and to check for invalid inputs.
1561 Use mbsnwidth to count columns correctly. Account for tabs, too.
1563 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
1564 (extend_location): New function.
1567 Handle CRLF in C code rather than in Lex code.
1568 (YY_INPUT): New macro.

1571 Scan UCNs, even though we don't fully handle them yet.
1572 (convert_ucn_to_byte): New function.
1574 Handle backslash-newline correctly in C code.
1575 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
1576 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;

1580 YY_STEP after space, newline, vertical-tab.
1581 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
1583 (letter, id): Don't assume ASCII; e.g., spell out a-z.
1585 ({int}, handle_action_dollar, handle_action_at): Check for integer
1588 (YY_STEP): Omit trailing semicolon, so that it's more like C.
1590 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
1591 as well as \000. Check for UCHAR_MAX, not 255.
1592 Allow \x with an arbitrary positive number of digits, as in C.
1593 Check for overflow here.
1594 Allow \? and UCNs, for compatibility with C.
1596 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
1597 with quote slot used by complain_at.
1599 * tests/input.at: Add tests for backslash-newline, m4 quotes
1600 in symbols, long literals, and funny escapes in strings.
1602 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
1603 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

1616 2002-11-02 Paul Eggert <eggert@twinsun.com>
1618 * src/reader.c: Don't include quote.h; not needed.

1623 bug in trigraph handling.
1625 * src/output.c (prepare_symbols): When printing token names,
1626 escape "[" as "@<:@" and likewise for "]".
1628 * src/system.h (errno): Remove declaration, as we are now
1629 assuming C89 or better, and C89 guarantees errno.
1631 2002-10-30 Paul Eggert <eggert@twinsun.com>
1633 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
1634 Check for close failures.
1635 * src/files.h (xfclose): Return void, not int, since it always
1637 * src/files.c (xfclose): Likewise. Report I/O error if ferror
1639 * src/output.c (output_skeleton): Use xfclose rather than fclose
1640 and ferror. xfclose now checks ferror.
1642 * data/glr.c (YYLEFTMOST_STATE): Remove.
1643 (yyreportTree): Use a stack-based leftmost state. This avoids
1644 our continuing battles with bogus warnings about initializers.
1646 2002-10-30 Akim Demaille <akim@epita.fr>
1648 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

1657 2002-10-24 Paul Eggert <eggert@twinsun.com>
1661 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
1662 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
1663 we use malloc. Don't assume 'A' through 'Z' are contiguous.
1664 Don't assume strdup exists; POSIX says its an XSI extension.
1665 Check for buffer overflow on input.
1667 2002-10-24 Akim Demaille <akim@epita.fr>
1669 * src/output.c (output_skeleton): Don't disable M4sugar comments
1670 too soon: it results in comments being expanded.
1671 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
1674 2002-10-24 Akim Demaille <akim@epita.fr>
1676 * data/yacc.c (m4_int_type): New.
1677 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
1678 char' as only yacc.c wants K&R portability.
1679 * data/glr.c (yysigned_char): Remove.
1680 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
1681 Reported by Quoc Peyrot.
1683 2002-10-23 Paul Eggert <eggert@twinsun.com>
1685 * src/main.c (main): With --trace=time, report times even if a
1686 non-fatal error occurs. Formerly, the times were reported in some
1687 such cases but not in others.
1688 * src/reader.c (reader): Just return if a complaint has been issued,
1689 instead of exiting, so that 'main' can report times.
1691 2002-10-22 Akim Demaille <akim@epita.fr>
1693 * src/system.h: Include sys/types.
1694 Reported by Bert Deknuydt.
1696 2002-10-23 Paul Eggert <eggert@twinsun.com>
1698 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
1699 Suggested by Art Haas.

1703 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
1704 decl; not needed any more.
1705 * src/main.c (main): Use return to exit, undoing yesterday's change.
1706 The last OS that we could find where this wouldn't work is
1707 SunOS 3.5, and that's too old to worry about now.
1709 * data/glr.c (struct yyltype): Define members even when not
1710 doing locations. This is more consistent with yacc.c, and it
1711 works around the following bug reports:
1712 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
1713 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
1715 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
1716 @acronym consistently. Standardize on "Yacc" instead of "YACC",
1717 "Algol" instead of "ALGOL". Give a bit more history about BNF.
1719 2002-10-22 Akim Demaille <akim@epita.fr>
1723 2002-10-21 Paul Eggert <eggert@twinsun.com>
1725 Be consistent about 'bool'; the old code used an enum in one
1726 module and an int in another, and this violates the C standard.
1727 * m4/stdbool.m4: New file, from coreutils 4.5.3.
1728 * configure.ac (AC_HEADER_STDBOOL): Add.
1729 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

1731 * src/symtab.c (hash_compare_symbol_t): Likewise.
1732 * src/system.h (bool, false, true): Use a definition consistent
1733 with ../lib/hash.c. All uses changed.
1735 * src/complain.c (warning_issued): Renamed from warn_message_count,
1736 so that we needn't worry about integer overflow (!).
1737 Now of type bool. All uses changed.
1738 (complaint_issued): Renamed from complain_message_count; likewise.
1740 * src/main.c (main): Use exit to exit with failure.
1742 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
1743 rather than 1 and 0.
1744 * src/main.c (main): Likewise.
1745 * src/getargs.c (getargs): Likewise.
1746 * src/reader.c (reader): Likewise.
1748 * src/getarg.c (getargs): Remove duplicate code for
1749 "Try `bison --help'".
1751 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
1752 What was that "2" for?
1754 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
1755 * src/getargs.c (usage): Likewise.
1757 * src/getargs.c (getargs): When there are too few operands, report
1758 the last one. When there are too many, report the first extra
1759 one. This is how diffutils does it.
1761 2002-10-20 Paul Eggert <eggert@twinsun.com>
1763 Remove K&R vestiges.
1764 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
1765 * src/complain.c (VA_START): Remove. Assume prototypes.
1766 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
1767 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
1768 fatal): Assume prototypes.
1769 * src/complain.h: Assume prototypes.
1770 * src/system.h (PARAMS): Remove.
1771 Include <limits.h> unconditionally, since it's guaranteeed even
1772 for a freestanding C89 compiler.
1773 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
1774 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
1776 2002-10-20 Akim Demaille <akim@epita.fr>
1778 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

1781 (yyresolveStates, yyresolveAction, yyresolveStack)
1782 (yyprocessOneStack): Use them.
1783 (yy_reduce_print): New.

1792 (b4_c_function_decl, b4_c_ansi_function_def)
1793 (b4_c_ansi_function_decl): New.
1794 Change the interpretation of the arguments: before `int, foo', now
1796 * data/yacc.c (yyparse): Prototype and define thanks to these.
1797 Adjust b4_c_function_def uses.
1798 * data/glr.c (yyparse): Likewise, but ANSI only.
1800 2002-10-20 Akim Demaille <akim@epita.fr>
1802 * src/output.c (prepare): Move the definition of `tokens_number',
1803 `nterms_number', `undef_token_number', `user_token_number_max'
1805 (prepare_tokens): Here.
1806 (prepare_tokens): Rename as...
1807 (prepare_symbols): this.
1808 (prepare): Move the definition of `rules_number' to...
1809 (prepare_rules): here.
1810 (prepare): Move the definition of `last', `final_state_number',
1811 `states_number' to...
1812 (prepare_states): here.

1832 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
1835 2002-10-19 Paul Eggert <eggert@twinsun.com>
1837 Do not create a temporary file, as that involves security and
1838 cleanup headaches. Instead, use a pair of pipes.
1839 Derived from a suggestion by Florian Krohm.
1840 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
1841 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

1854 * src/scan-skel.l (readpipe): Remove decl.
1855 (scan_skel): New function, to be used in place of m4_invoke.
1856 Read from stream rather than file.
1858 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
1859 float, as this generates a warning on Solaris 8 + GCC 3.2 with
1860 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
1861 this generates a more-accurate value anyway.
1863 * lib/timevar.c (timervar_accumulate): Rename locals to
1864 avoid confusion with similarly-named more-global.
1865 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
1867 * src/output.c (prepare): Use xstrdup to convert char const *
1868 to char *, to avoid GCC warning.
1870 2002-10-19 Akim Demaille <akim@epita.fr>
1872 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,

1875 * data/yacc.c (YYLEX): Pass a yylex return type to
1878 2002-10-19 Akim Demaille <akim@epita.fr>
1880 Prototype support of %lex-param and %parse-param.
1882 * src/parse-gram.y: Add the definition of the %lex-param and
1883 %parse-param tokens, plus their rules.
1884 Drop the `_' version of %glr-parser.
1886 * src/scan-gram.l (INITIAL): Scan them.
1887 * src/muscle_tab.c: Comment changes.

1904 * src/getargs.c (usage): Take status as argument and exit
1906 Report the traditional `Try ... --help' message when status != 0.
1907 (usage, version): Don't take a FILE * as arg, it is pointless.
1908 (getargs): When there is an incorrect number of arguments, make it
1909 an error, and report it GNUlically thanks to `usage ()'.
1911 2002-10-18 Paul Eggert <eggert@twinsun.com>
1913 * data/glr.c (yyreportParseError): Don't assume that sprintf
1914 yields the length of the printed string, as this is not true
1915 on SunOS 4.1.4. Reported by Peter Klein.
1917 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
1918 * tests/conflicts.at (%nonassoc and eof): Likewise.
1919 Fixes SunOS 4.1.4 test failure reported by Peter Klein.

1930 instead of an adhoc scheme.
1931 * src/scan-gram.l: Remove trailing debugging code.
1933 2002-10-16 Paul Eggert <eggert@twinsun.com>
1935 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
1938 * NEWS: Officially drop support for building Bison with K&R C,
1939 since it didn't work anyway and it's not worth worrying about.
1940 * Makefile.maint (wget_files): Remove ansi2knr.c.
1941 (ansi2knr.c-url_prefix): Remove.
1942 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

1946 2002-10-15 Paul Eggert <eggert@twinsun.com>
1948 Stop using the "enum_" trick for K&R-style function definitions;
1949 it confused me, and I was the author! Instead, assume that people
1950 who want to use K&R C compilers (when using these modules in GCC,
1951 perhaps?) will run ansi2knr.
1953 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
1954 All uses of "enum_" changed to "enum ".
1955 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

1968 static functions simply to provide their prototypes.

2043 tests/cxx-type.at, tests/headers.at, tests/input.at,
2044 tests/regression.at, tests/synclines.at, tests/torture.at:
2045 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
2046 so that the tests still work even if POSIXLY_CORRECT is set.
2047 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
2049 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
2050 for portability to K&R hosts. Fix typo: signed char is guaranteed
2051 only to 127, not to 128.
2052 * data/glr.c (yysigned_char): New type.
2053 * data/yacc.c (yysigned_char): Likewise.
2054 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
2056 2002-10-13 Paul Eggert <eggert@twinsun.com>
2058 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
2059 true due to limited range of data type" warning from GCC.
2061 * data/c.m4 (b4_token_defines): Protect against double-inclusion
2062 by wrapping enum yytokentype's definition inside #ifndef
2063 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
2065 2002-10-13 Akim Demaille <akim@epita.fr>
2067 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
2068 Un yy- yyrhs to avoid the name clash with the global YYRHS.
2070 2002-10-13 Akim Demaille <akim@epita.fr>
2072 * Makefile.maint: Update from Autoconf 2.54.
2073 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
2075 2002-10-13 Akim Demaille <akim@epita.fr>
2077 * src/print.c (print_state): Separate the list of solved conflicts
2078 from the other items.
2079 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
2081 2002-10-13 Akim Demaille <akim@epita.fr>
2083 Let nondeterministic skeletons be usable with deterministic
2086 With the patch, GAWK compiled by GCC without -O2 passes its test
2087 suite using a GLR parser driven by LALR tables. It fails with -O2
2088 because `struct stat' gives two different answers on my machine:
2089 88 (definition of an auto var) and later 96 (memset on this var).
2090 Hence the stack is badly corrumpted. The headers inclusion is to
2091 blame: if I move the awk.h inclusion before GLR's system header
2092 inclusion, the two struct stat have the same size.
2094 * src/tables.c (pack_table): Always create conflict_table.
2095 (token_actions): Always create conflict_list.
2096 * data/glr.c (YYFLAG): Remove, unused.
2098 2002-10-13 Akim Demaille <akim@epita.fr>
2100 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
2102 (VALGRIND, GXX): New.
2103 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
2104 * tests/bison.in: Run $PREBISON a pre-command.
2105 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
2106 (maintainer-check-g++): New.
2107 * Makefile.am (maintainer-check): New.
2109 2002-10-13 Akim Demaille <akim@epita.fr>
2111 * data/glr.c: Formatting changes.
2112 Tweak some trace messages to match yacc.c's.
2114 2002-10-13 Akim Demaille <akim@epita.fr>
2116 GLR parsers sometimes raise parse errors instead of performing the
2118 Reported by Charles-Henry de Boysson.
2120 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
2121 check the length of the traces when %glr.
2122 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
2124 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
2126 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
2127 (yyltype): Remove the yy prefix from the member names.
2128 (yytable): Complete its comment.
2129 (yygetLRActions): Map error action number from YYTABLE from
2131 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
2132 (which was a bug: it should have been YYTABEL_NINF, and yet it was
2133 not satisfying as we could compare an YYACTION computed from
2134 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
2135 only value for error actions.
2136 (yyreportParseError): In verbose parse error messages, don't issue
2137 `error' in the list of expected tokens.
2138 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
2139 next action to perform to match glr.c's decoding.
2140 (yytable): Complete its comment.

2144 Fix problem reported by Henrik Grubbstroem in

2146 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
2147 because the Bison parser reads the second action before reducing
2149 * src/scan-gram.l (rule_length): New static var.
2150 Use it to keep track of the rule length in the scanner, since
2151 we can't expect the parser to be in lock-step sync with the scanner.
2152 (handle_action_dollar, handle_action_at): Use this var.
2153 * tests/actions.at (Exotic Dollars): Test for the problem.
2155 2002-10-12 Paul Eggert <eggert@twinsun.com>
2157 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
2158 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
2159 Include <sys/time.h> when checking for clock_t and struct tms.
2160 Use same include order as source.
2161 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
2162 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
2164 * lib/timevar.c: Update copyright date and clarify comments.
2165 (get_time) [IN_GCC]: Keep the GCC version for reference.
2167 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
2168 GCC version as of today, then merge Bison's changes.
2169 Change "GCC" to "Bison" in copyright notice. timevar.def's
2170 author is Akim, so change that too.
2172 * src/reader.c (grammar_current_rule_check):
2173 Don't worry about the default action if $$ is untyped.
2174 Prevents bogus warnings reported by Jim Gifford in
2175 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
2177 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
2178 * data/glr.c, data/lalr1.cc, data/yacc.c:
2179 Output token definitions before the first part of user declarations.
2180 Fixes compatibility problem reported by Jim Gifford for kbd in

2203 Portability fixes for bitsets; this also avoids several GCC
2206 * lib/abitset.c: Include <stddef.h>, for offsetof.
2207 * lib/lbitset.c: Likewise.
2209 * lib/abitset.c (abitset_bytes): Return a size that is aligned
2210 properly for vectors of objects. Do not assume that adding a

2212 properly aligned for the whole union.
2213 * lib/bitsetv.c (bitsetv_alloc): Likewise.

2253 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
2255 Do not use "struct bitset_struct" to mean different things in
2256 different modules. Not only is this confusing, it violates
2257 the C Standard, which requires that structure types in different
2258 modules must be compatible if one is to be passed to the other.

2302 2002-10-06 Paul Eggert <eggert@twinsun.com>
2304 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
2305 the same width as int. This reapplies a hunk of the 2002-08-12 patch
2306 <http://mail.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
2307 which was inadvertently undone by the 2002-09-30 patch.

2321 the portable Standard C character set.
2323 The GNU coding standard says CFLAGS and YFLAGS are reserved
2324 for the installer to set.

2338 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
2340 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
2341 interpreted as signed.

2907 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
2909 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
2910 for the time being: %locations ought to provide it to yyerror.
2912 2002-07-25 Akim Demaille <akim@epita.fr>
2914 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

5181 2002-02-14 Paul Eggert <eggert@twinsun.com>
5183 Remove the support for C++ namespace cleanliness; it was
5184 causing more problems than it was curing, since it didn't work

5281 (output_skeleton): Don't look for the skeleton location, let m4 do
5283 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
5285 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
5286 (prepare): Given that for the time being changesyntax is not
5287 usable in M4, rename the muscles using `-' to `_'.

5289 * src/output.h (actions_output, guards_output)
5290 (token_definitions_output): Adjust prototypes.

5319 * src/bison.simple (YYSIZE_T): Do not define merely because
5320 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
5321 On some platforms, <alloca.h> does not declare YYSTD (size_t).

5325 Fix `%nonassoc and eof'.
5327 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
5328 which were not properly copied! Replace

5389 * src/system.h: Need to define __attribute__ away for non-GCC
5390 compilers as well (i.e. the vendor C compiler).
5391 Suggested by Albert Chin-A-Young.
5393 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
5395 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
5396 canonical definition.
5397 * src/system.h: Use the canonical definition for PARAMS (avoids
5398 a conflict with the macro from lib/hash.h).

5402 * configure.in: Use AC_FUNC_STRNLEN.
5403 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
5405 2002-01-09 Akim Demaille <akim@epita.fr>
5407 * src/files.c, src/files.h (output_infix): New.
5408 (tab_extension): Remove.
5409 (compute_base_names): Compute the former, drop the latter.
5410 * src/output.c (prepare): Insert the muscles `output-infix', and
5412 * src/parse-skel.y (string, string.1): New.
5413 (section.header): Use it.
5414 (section.yacc): Remove.
5415 (prefix): Remove too.
5416 * src/scan-skel.l: Adjust.
5417 * src/bison.simple, src/bison.hairy: Adjust.
5419 2002-01-09 Akim Demaille <akim@epita.fr>
5421 * configure.in (WERROR_CFLAGS): Compute it.
5422 * src/Makefile.am (CFLAGS): Pass it.
5423 * tests/atlocal.in (CFLAGS): Idem.
5424 * src/files.c: Fix a few warnings.
5425 (get_extension_index): Remove, unused.
5427 2002-01-08 Akim Demaille <akim@epita.fr>
5429 * src/getargs.c (AS_FILE_NAME): New.
5430 (getargs): Use it to convert DOSish file names.
5431 * src/files.c (base_name): Rename as full_base_name to avoid
5432 clashes with `base_name ()'.
5433 (filename_split): New.
5434 (compute_base_names): N-th rewrite, using filename_split.
5436 2002-01-08 Akim Demaille <akim@epita.fr>
5438 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
5439 New, stolen from the Fileutils 4.1.
5440 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
5441 * configure.in: Check for the presence of memrchr, and of its
5444 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
5446 * lib/hash.h (__P): Added definition for this macro.
5447 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
5448 BUILT_SOURCES, to ensure they are generated first.
5449 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
5450 %error-verbose to allow bootstrapping with bison 1.30x.
5452 2002-01-06 Akim Demaille <akim@epita.fr>
5454 * src/reader.c (parse_braces): Don't fetch the next char, the
5455 convention is to fetch on entry.
5456 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
5457 'switch' without a following semicolon.
5458 * tests/regression.at (braces parsing): New.
5460 2002-01-06 Akim Demaille <akim@epita.fr>
5462 Bison is dead wrong in its RR conflict reports.
5464 * tests/torture.at (GNU Cim Grammar): New.
5465 * src/conflicts.c (count_rr_conflicts): Fix.
5467 2002-01-06 Akim Demaille <akim@epita.fr>
5469 Creating package.m4 from configure.ac causes too many problems.
5471 * tests/Makefile.am (package.m4): Create it by hand,
5472 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
5474 2002-01-06 Akim Demaille <akim@epita.fr>
5476 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
5479 2002-01-04 Paul Eggert <eggert@twinsun.com>
5481 * doc/bison.texinfo (Debugging):
5482 Remove YYSTDERR; it's no longer defined or used.
5483 Also, s/cstdio.h/cstdio/.
5485 2002-01-03 Akim Demaille <akim@epita.fr>
5487 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
5489 2002-01-03 Akim Demaille <akim@epita.fr>
5491 * src/parse-skel.y (process_skeleton): Don't bind the parser's
5492 tracing code to --trace, wait for a better --trace option, with
5495 2002-01-03 Akim Demaille <akim@epita.fr>
5497 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
5498 The ISO C++ standard is extremely clear about it: stderr is
5499 considered a macro, not a regular symbol (see table 94 `Header
5500 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
5501 Therefore std:: does not apply to it. It still does with fprintf.
5502 Also, s/cstdio.h/cstdio/.
5504 2002-01-03 Akim Demaille <akim@epita.fr>
5506 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
5507 for non system headers.
5509 2002-01-02 Akim Demaille <akim@epita.fr>
5511 Equip the skeleton chain with location tracking, runtime trace,
5512 pure parser and scanner.
5514 * src/parse-skel.y: Request a pure parser, locations, and prefix
5516 (%union): Having several members with the same type does not help
5517 type mismatches, simplify.
5518 (YYPRINT, yyprint): New.
5519 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
5522 * src/scan-skel.l: Adjust to these changes.
5523 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
5524 (LOCATION_PRINT, skel_control_t): New.
5526 2001-12-30 Akim Demaille <akim@epita.fr>
5528 * src/parse-skel.y: Get rid of the shift/reduce conflict:
5529 replace `gb' with BLANKS.
5530 * src/scan-skel.l: Adjust.
5532 2001-12-30 Akim Demaille <akim@epita.fr>
5534 * src/system.h: We don't need nor want bcopy.
5535 Throw away MS-DOS crap: we don't need getpid.
5536 * configure.in: We don't need strndup. It was even causing
5537 problems: because Flex includes the headers *before* us,
5538 _GNU_SOURCE is not defined by config.h, and therefore strndup was
5540 * lib/xstrndup.c: New.
5541 * src/scan-skel.l: Use it.
5542 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
5543 * src/parse-skel.y: Use %directives instead of #defines.
5545 2001-12-30 Akim Demaille <akim@epita.fr>
5547 * src/skeleton.h: New.
5548 * src/output.c (output_parser, output_master_parser): Remove, dead
5550 * src/output.h (get_lines_number, actions_output, guards_output)
5551 (token_definitions_output): Prototype them.
5552 * src/parse-skel.y: Add the license notice.
5553 Include output.h and skeleton.h.
5554 (process_skeleton): Returns void, and takes a single parameter.
5555 * src/scan-skel.l: Add the license notice.
5557 Don't use %option yylineno: it seems that then Flex imagines
5558 REJECT has been used, and therefore it won't reallocate its
5559 buffers (which makes no other sense to me than a bug). It results
5560 in warnings for `unused: yy_flex_realloc'.
5562 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
5564 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
5565 (MUSCLE_INSERT_PREFIX): ...to there.
5566 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
5567 (MUSCLE_INSERT_PREFIX): Move from here...
5569 * src/bison.hairy: Add a section directive. Put braces around muscle
5570 names. This parser skeleton is still broken, but Bison should not
5571 choke on a bad muscle 'syntax'.
5572 * src/bison.simple: Add a section directive. Put braces around muscle
5575 * src/files.h (strsuffix, stringappend): Add declarations.
5576 (tab_extension): Add declaration.
5577 (short_base_name): Add declaration.
5579 * src/files.c (strsuffix, stringappend): No longer static. These
5580 functions are used in the skeleton parser.
5581 (tab_extension): New.
5582 (compute_base_names): Use the computations done in this function
5583 to guess if the generated parsers should have '.tab' in their
5585 (short_base_name): No longer static.
5587 * src/output.c (output_skeleton): New.
5588 (output): Disable call to output_master_parser, and give a try to
5589 a new skeleton handling system.
5590 (guards_output, actions_output): No longer static.
5591 (token_definitions_output, get_lines_number): No longer static.
5593 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
5595 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
5598 * src/parse-skel.y: New file.
5599 * src/scan-skel.l: New file.
5601 2001-12-29 Akim Demaille <akim@epita.fr>
5603 %name-prefix is broken.
5605 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
5606 Adjust all dependencies.
5607 * tests/headers.at (export YYLTYPE): Strengthen this test: use
5610 Renaming yylval but not yylloc is not consistent. Now we do.
5612 * src/bison.simple: Prefix yylloc if used.
5613 * doc/bison.texinfo (Decl Summary): Document that.
5615 2001-12-29 Akim Demaille <akim@epita.fr>
5617 * doc/bison.texinfo: Promote `%long-directive' over
5619 Remove all references to fixed-output-files, yacc is enough.
5621 2001-12-29 Akim Demaille <akim@epita.fr>
5623 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
5624 user prologue. These are defaults.
5625 * tests/actions.at (Mid-rule actions): Make sure the user can
5626 define YYDEBUG and YYERROR_VERBOSE.
5628 2001-12-29 Akim Demaille <akim@epita.fr>
5630 * src/output.c (header_output): Don't forget to export YYLTYPE and
5632 * tests/headers.at (export YYLTYPE): New, make sure it does.
5633 * tests/regression.at (%union and --defines, Invalid CPP headers):
5635 * tests/headers.at: here.
5637 2001-12-29 Akim Demaille <akim@epita.fr>
5639 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
5641 2001-12-29 Akim Demaille <akim@epita.fr>
5643 * tests/actions.at (Mid-rule actions): Output on a single line
5646 2001-12-29 Akim Demaille <akim@epita.fr>
5648 * doc/bison.texinfo: Formatting changes.
5650 2001-12-29 Akim Demaille <akim@epita.fr>
5652 Don't store the token defs in a muscle, just be ready to output it
5653 on command. Now possible via `symbols'. Fixes a memory leak.
5655 * src/output.c (token_definitions_output): New.
5656 (output_parser, header_output): Use it.
5657 * src/reader.c (symbols_save): Remove.
5659 2001-12-29 Akim Demaille <akim@epita.fr>
5661 * src/bison.simple: Do not provide a default for YYSTYPE and
5662 YYLTYPE before the user's prologue. Otherwise it's hardly... a
5665 2001-12-29 Akim Demaille <akim@epita.fr>
5667 Mid-rule actions are simply... ignored!
5669 * src/reader.c (readgram): Be sure to attach mid-rule actions to
5670 the empty-rule associated to the dummy symbol, not to the host
5672 * tests/actions.at (Mid-rule actions): New.
5674 2001-12-29 Akim Demaille <akim@epita.fr>
5678 * src/reader.c (reader): Free grammar.
5680 2001-12-29 Akim Demaille <akim@epita.fr>
5684 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
5685 since it allocates it for each state, although only one is needed.
5686 (allocate_storage): Do it here.
5688 2001-12-29 Akim Demaille <akim@epita.fr>
5690 * src/options.h, src/options.c (create_long_option_table): Rename
5692 (long_option_table_new): this, with a clearer prototype.
5693 (percent_table): Remove, unused,
5694 * src/getargs.c (getargs): Adjust.
5696 2001-12-29 Akim Demaille <akim@epita.fr>
5698 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
5699 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
5702 2001-12-29 Akim Demaille <akim@epita.fr>
5704 * src/lalr.c (build_relations): Rename `states' as `states1'.
5705 Sorry, I don't understand exactly what it is, no better name...
5707 2001-12-29 Akim Demaille <akim@epita.fr>
5709 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
5710 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
5711 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
5714 2001-12-29 Akim Demaille <akim@epita.fr>
5716 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
5719 2001-12-29 Akim Demaille <akim@epita.fr>
5721 * src/reader.c, src/reader.h (user_toknums): Remove.
5722 Adjust all users to use symbols[i]->user_token_number.
5724 2001-12-29 Akim Demaille <akim@epita.fr>
5726 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
5727 Adjust all users to use symbols[i]->prec or ->assoc.
5729 2001-12-29 Akim Demaille <akim@epita.fr>
5731 * src/reader.c, src/reader.h (tags): Remove.
5732 Adjust all users to use symbols[i]->tag.
5734 2001-12-29 Akim Demaille <akim@epita.fr>
5736 * src/gram.h, src/gram.c (symbols): New, similar to state_table
5738 * src/reader.c (packsymbols): Fill this table.
5740 * src/conflicts.c (resolve_sr_conflict): Adjust.
5741 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
5743 Use symbols[i]->tag instead of tags[i].
5745 2001-12-29 Akim Demaille <akim@epita.fr>
5747 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
5748 In addition, put a comment in there, to replace...
5749 * tests/regression.at (%union and C comments): Remove.
5751 2001-12-29 Akim Demaille <akim@epita.fr>
5753 * tests/regression.at (Web2c Actions): Blindly move the actual
5754 output as expected output. The contents *seem* right to me, but I
5755 can't pretend reading perfectly parser tables... Nonetheless, all
5756 the other tests pass correctly, the table look OK, even though the
5757 presence of `$axiom' is to be noted: AFAICS it is useless (but
5760 2001-12-29 Akim Demaille <akim@epita.fr>
5762 * src/reader.c (readgram): Don't add the rule 0 if there were no
5763 rules read. In other words, add it _after_ having performed
5764 grammar sanity checks.
5765 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
5767 2001-12-29 Akim Demaille <akim@epita.fr>
5769 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
5770 visible, and some states have now a different number.
5772 2001-12-29 Akim Demaille <akim@epita.fr>
5774 * src/reader.c (readgram): Bind the initial rule's lineno to that
5776 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
5777 (Solved SR Conflicts): Adjust rule 0's line number.
5779 2001-12-29 Akim Demaille <akim@epita.fr>
5781 Fix the `GAWK Grammar' failure.
5783 * src/LR0.c (final_state): Initialize to -1 so that we do compute
5784 the reductions of the first state which was mistakenly confused
5785 with the final state because precisely final_state was initialized
5787 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
5788 now noticed by Bison.
5789 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
5790 have a reduction on $default.
5792 2001-12-29 Akim Demaille <akim@epita.fr>
5794 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
5796 * src/closure.c (print_closure): Likewise.
5797 * src/derives.c (print_derives): Likewise.
5798 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
5801 2001-12-29 Akim Demaille <akim@epita.fr>
5803 * src/lalr.c (lookaheads_print): New.
5804 (lalr): Call it when --trace-flag.
5805 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
5808 2001-12-29 Akim Demaille <akim@epita.fr>
5810 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
5811 when walking through ritem, even via rule->rhs.
5812 * src/reduce.c (dump_grammar, useful_production, reduce_output)
5813 (useful_production, useless_nonterminals): Likewise.
5814 (reduce_grammar_tables): Likewise, plus update nritems.
5815 * src/nullable.c (set_nullable): Likewise.
5816 * src/lalr.c (build_relations): Likewise.
5817 * tests/sets.at (Nullable): Adjust.
5818 Fortunately, now, the $axiom is no longer nullable.
5820 2001-12-29 Akim Demaille <akim@epita.fr>
5822 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
5824 * src/gram.c (ritem_longest_rhs): Likewise.
5825 * src/reduce.c (nonterminals_reduce): Likewise.
5826 * src/print_graph.c (print_graph): Likewise.
5827 * src/output.c (output_rule_data): Likewise.
5828 * src/nullable.c (set_nullable): Likewise.
5830 2001-12-29 Akim Demaille <akim@epita.fr>
5832 * src/output.c: Comment changes.
5834 2001-12-27 Paul Eggert <eggert@twinsun.com>
5836 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
5837 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
5838 Sparc, as they were causing more porting problems than the
5839 (minor) performance improvement was worth.
5841 Also, catch up with 1.31's YYSTD.
5843 2001-12-27 Akim Demaille <akim@epita.fr>
5845 * src/output.c (output_gram): Rely on nritems, not the
5846 0-sentinel. See below.
5847 Use -1 as separator, not 0.
5848 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
5849 Rely on -1 as separator in yyrhs, instead of 0.
5850 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
5851 twice `Now at end of input', therefore there are two lines less to
5854 2001-12-27 Akim Demaille <akim@epita.fr>
5856 * tests/regression.at (Unresolved SR Conflicts):
5857 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
5860 2001-12-27 Akim Demaille <akim@epita.fr>
5862 * src/LR0.c (new_state): Recognize the final state by the fact it
5863 is reached by eoftoken.
5864 (insert_start_shifting_state, insert_eof_shifting_state)
5865 (insert_accepting_state, augment_automaton): Remove, since now
5866 these states are automatically computed from the initial state.
5867 (generate_states): Adjust.
5868 * src/print.c: When reporting a rule number to the user, substract
5869 1, so that the axiom rule is rule 0, and the first user rule is 1.
5870 * src/reduce.c: Likewise.
5871 * src/print_graph.c (print_core): For the time being, just as for
5872 the report, depend upon --trace-flags to dump the full set of
5874 * src/reader.c (readgram): Once the grammar read, insert the rule
5875 0: `$axiom: START-SYMBOL $'.
5876 * tests/set.at: Adjust: rule 0 is now displayed, and since the
5877 number of the states has changed (the final state is no longer
5878 necessarily the last), catch up.
5880 2001-12-27 Akim Demaille <akim@epita.fr>
5882 Try to make the use of the eoftoken valid. Given that its value
5883 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
5884 is used instead of > 0 where appropriate, (ii), depend upon nritems
5885 instead of the 0-sentinel.
5887 * src/gram.h, src/gram.c (nritems): New.
5888 Expected to be duplication of nitems, but for the time being...
5889 * src/reader.c (packgram): Assert nritems and nitems are equal.
5890 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
5891 * src/closure.c (print_closure, print_fderives): Likewise.
5892 * src/gram.c (ritem_print): Likewise.
5893 * src/print.c (print_core, print_grammar): Likewise.
5894 * src/print_graph.c: Likewise.
5896 2001-12-27 Akim Demaille <akim@epita.fr>
5898 * src/main.c (main): If there are complains after grammar
5899 reductions, then output the report anyway if requested, then die.
5900 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
5901 * src/reader.c (eoftoken): New.
5902 (parse_token_decl): If the token being defined has value `0', it
5904 (packsymbols): No longer hack `tags' to insert `$' by hand.
5905 Be sure to preserve the value of the eoftoken.
5906 (reader): Make sure eoftoken is defined.
5907 Initialize nsyms to 0: now eoftoken is created just like the others.
5908 * src/print.c (print_grammar): Don't special case the eof token.
5909 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
5910 lie anyway, albeit pleasant.
5911 * tests/calc.at: Exercise error messages with eoftoken.
5912 Change the grammar so that empty input is invalid.
5913 Adjust expectations.
5914 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
5916 2001-12-27 Akim Demaille <akim@epita.fr>
5918 * configure.in: Check the protos of strchr ans strspn.
5919 Replace strchr if needed.
5920 * src/system.h: Provide the protos of strchr, strspn and memchr if
5922 * lib/strchr.c: New.
5923 * src/reader.c (symbols_save): Use strchr.
5925 2001-12-27 Akim Demaille <akim@epita.fr>
5927 * src/print.c, src/print_graph.c (escape): New.
5928 Use it to quote the TAGS outputs.
5929 * src/print_graph.c (print_state): Now errors are in red, and
5930 reductions in green.
5931 Prefer high to wide: output the state number on a line of its own.
5933 2001-12-27 Akim Demaille <akim@epita.fr>
5935 * src/state.h, src/state.c (reductions_new): New.

5956 2001-12-27 Akim Demaille <akim@epita.fr>
5958 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
5959 * src/print.c: here.
5960 (lookaheadset, shiftset): New, used as additional storage by
5962 (print_results): Adjust.
5963 (print_shifts, print_gotos, print_errs): New, extracted from...
5964 (print_actions): here.
5965 * src/print_graph.c (print_actions): Remove dead code.
5967 2001-12-27 Akim Demaille <akim@epita.fr>
5969 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
5972 2001-12-27 Akim Demaille <akim@epita.fr>
5974 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
5975 (build_relations): Adjust.
5977 2001-12-27 Akim Demaille <akim@epita.fr>
5979 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
5982 2001-12-27 Akim Demaille <akim@epita.fr>
5984 * src/reader.c (packgram): Catch nitems overflows.
5986 2001-12-27 Akim Demaille <akim@epita.fr>
5988 * src/files.c, src/files.h (guard_obstack): Remove.
5989 * src/output.c (output): Adjust.
5990 * src/reader.c (parse_braces): New, factoring...
5991 (copy_action, copy_guard): these two which are renamed as...
5992 (parse_action, parse_guard): these.
5993 As a voluntary consequence, using braces around guards is now
5996 2001-12-27 Akim Demaille <akim@epita.fr>
5998 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
5999 * src/reader.c (symbol_list): `guard' and `guard_line' are new
6001 (symbol_list_new): Adjust.
6002 (copy_action): action_line is the first line, not the last.
6003 (copy_guard): Just as for actions, store the `action' only, not
6004 the switch/case/break flesh.
6005 Don't parse the user action that might follow the guard, let...
6006 (readgram): do it, i.e., now, there can be an action after a
6008 In other words the guard is just explicitly optional.
6010 * src/output.c (guards_output): New.
6011 (output_parser): Call it when needed.
6012 (output): Also free the guard and attrs obstacks.
6013 * src/files.c, src/files.h (obstack_save): Remove.
6014 (output_files): Remove.
6015 As a result, if one needs the former `.act' file, using an
6016 appropriate skeleton which requires actions and guards is now
6018 * src/main.c (main): Adjust.
6019 * tests/semantic.at: New.
6020 * tests/regression.at: Use `input.y' as input file name.
6021 Avoid 8+3 problems by requiring input.c when the test needs the
6024 2001-12-27 Akim Demaille <akim@epita.fr>
6026 * src/reader.c (symbol_list_new): Be sure to initialize all the
6029 2001-12-27 Akim Demaille <akim@epita.fr>
6031 All the hacks using a final pseudo state are now useless.
6033 * src/LR0.c (set_state_table): state_table holds exactly nstates.
6034 * src/lalr.c (nLA): New.
6035 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
6036 instead of lookaheadsp from the pseudo state (nstate + 1).
6038 2001-12-27 Akim Demaille <akim@epita.fr>
6040 * src/output.c (action_row, token_actions): Use a state_t instead
6041 of a integer, and nlookaheads instead of the following state's
6044 2001-12-27 Akim Demaille <akim@epita.fr>
6046 * src/conflicts.c (log_resolution, flush_shift)
6047 (resolve_sr_conflict, set_conflicts, solve_conflicts)
6048 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
6049 (conflicts_print, print_reductions): Use a state_t instead of an
6050 integer when referring to a state.
6051 As much as possible, depend upon nlookaheads, instead of the
6052 `lookaheadsp' member of the following state (since lookaheads of
6053 successive states are successive, the difference between state n + 1
6054 and n served as the number of lookaheads for state n).
6055 * src/lalr.c (add_lookback_edge): Likewise.
6056 * src/print.c (print_core, print_actions, print_state)
6057 (print_results): Likewise.

6060 * src/conflicts.h: Adjust.
6062 2001-12-27 Akim Demaille <akim@epita.fr>
6064 * src/bison.hairy: Formatting/comment changes.
6066 Remove `register' indications.
6067 Add plenty of `static'.
6069 2001-12-27 Akim Demaille <akim@epita.fr>
6071 * src/output.c (prepare): Drop the muscle `ntbase' which
6073 * src/bison.simple: Formatting/comment changes.
6074 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
6075 is an undocumented synonym.
6077 2001-12-22 Akim Demaille <akim@epita.fr>
6079 * src/output.c (output_table_data): Change the prototype to use
6080 `int' for array ranges: some invocations do pass an int, not a
6082 Reported by Wayne Green.
6084 2001-12-22 Akim Demaille <akim@epita.fr>
6086 Some actions of web2c.y are improperly triggered.
6087 Reported by Mike Castle.
6089 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

6091 (Web2c Report): this.
6092 (Web2c Actions): New.
6094 2001-12-22 Akim Demaille <akim@epita.fr>
6096 Reductions in web2c.y are improperly reported.
6097 Reported by Mike Castle.
6099 * src/conflicts.c (print_reductions): Fix.
6100 * tests/regression.at (Web2c): New.
6102 2001-12-18 Akim Demaille <akim@epita.fr>
6104 Some host fail on `assert (!"foo")', which expands to
6105 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
6106 Reported by Nelson Beebee.
6108 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
6109 `#define it_succeeded 0' and `assert (it_succeeded)'.
6111 2001-12-17 Marc Autret <autret_m@epita.fr>
6113 * src/bison.simple: Don't hard code the skeleton line and filename.
6114 * src/output.c (output_parser): Rename 'line' as 'output_line'.
6115 New line counter 'skeleton_line' (skeleton-line muscle).
6117 2001-12-17 Paul Eggert <eggert@twinsun.com>
6119 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
6120 YYDEBUG must be defined to a nonzero value.
6122 * src/bison.simple (yytname): Do not assume that the user defines
6123 YYDEBUG to a properly parenthesized expression.
6125 2001-12-17 Akim Demaille <akim@epita.fr>
6127 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
6128 nlookaheads is a new member.
6130 * src/lalr.h (nlookaheads): Remove this orphan declaration.
6131 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
6134 2001-12-17 Akim Demaille <akim@epita.fr>
6136 * src/files.h, src/files.c (open_files, close_files): Remove.
6137 * src/main.c (main): Don't open/close files, nor invoke lex_free,
6139 * src/reader.c (reader): Do it.
6141 2001-12-17 Akim Demaille <akim@epita.fr>
6143 * src/conflicts.c (print_reductions): Formatting changes.
6145 2001-12-17 Akim Demaille <akim@epita.fr>
6147 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
6148 (flush_reduce): New.
6149 (resolve_sr_conflict): Adjust.
6151 2001-12-17 Akim Demaille <akim@epita.fr>
6153 * src/output.c (output_obstack): Be static and rename as...
6154 (format_obstack): this, to avoid any confusion with files.c's
6156 * src/reader.h (muscle_obstack): Move to...
6157 * src/output.h: here, since it's defined in output.c.
6159 2001-12-17 Akim Demaille <akim@epita.fr>
6161 * src/output.c (action_row, save_column, default_goto)
6162 (sort_actions, matching_state, pack_vector): Better variable
6165 2001-12-17 Akim Demaille <akim@epita.fr>
6167 * src/output.c: Various formatting changes.
6169 2001-12-17 Akim Demaille <akim@epita.fr>
6171 * src/files.c (output_files): Free the output_obstack.
6172 * src/main.c (main): Call print and print_graph conditionally.
6173 * src/print.c (print): Work unconditionally.
6174 * src/print_graph.c (print_graph): Work unconditionally.
6175 * src/conflicts.c (log_resolution): Output only if verbose_flag.
6177 2001-12-16 Marc Autret <autret_m@epita.fr>
6179 * src/output.c (actions_output): Fix. When we use %no-lines,
6180 there is one less line per action.
6182 2001-12-16 Marc Autret <autret_m@epita.fr>
6184 * src/bison.simple: Remove a useless #line directive.
6185 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
6186 * src/output.c (get_lines_number): New.
6187 (output_parser): Adjust, now takes care about the lines of a
6190 (actions_output): Computes the number of lines taken by actions.
6191 (output_master_parser): Insert new skeleton which is the name of
6192 the output parser file name.
6194 2001-12-15 Marc Autret <autret_m@epita.fr>
6196 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
6198 2001-12-15 Marc Autret <autret_m@epita.fr>
6200 * src/output.c (output_gram): Keep track of the hairy one.
6202 2001-12-15 Akim Demaille <akim@epita.fr>
6204 Make `make distcheck' work.
6206 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
6207 system.h which uses libgettext.h.
6209 2001-12-15 Akim Demaille <akim@epita.fr>
6211 * src/nullable.c (set_nullable): Useless rules must be skipped,
6212 otherwise, since we range over their symbols, we might look at a
6213 nonterminal which no longer ``exists'', i.e., it is not counted in
6214 `nvars', hence we overflow our arrays.
6216 2001-12-15 Akim Demaille <akim@epita.fr>
6218 The header can also be produced directly, without any obstack!
6221 * src/files.c, src/files.h (defines_obstack): Remove.
6222 (compute_header_macro): Global.
6223 (defines_obstack_save): Remove.
6224 * src/reader.c (parse_union_decl): No longer output to
6225 defines_obstack: its content can be found in the `stype' muscle
6227 (output_token_translations): Merge into...
6228 (symbols_output): this.
6230 (symbols_save): this.
6232 * src/output.c (header_output): New.
6235 2001-12-15 Akim Demaille <akim@epita.fr>
6237 * src/reader.c (parse_union_decl): Instead of handling two obstack
6238 simultaneously, use one to define the `stype' muscle, and use the
6239 value of the latter to fill defines_obstack.
6240 (copy_comment): Remove.
6241 (copy_comment2): Work for a single obstack.
6243 (copy_comment): this.
6245 2001-12-15 Akim Demaille <akim@epita.fr>
6247 * src/lex.c, src/lex.h (xgetc): No longer static.
6248 * src/reader.c (parse_union_decl): Revamp.
6250 2001-12-15 Akim Demaille <akim@epita.fr>
6252 Still making progress in separating Bison into (i) input, (ii)
6253 process, (iii) output: now we can directly output the parser file
6254 without using table_obstack at all.
6256 * src/files.c, src/files.h (table_obstack): Bye bye.
6257 (parser_file_name): New.
6258 * src/files.c (compute_output_file_names): Compute it.
6259 * src/output.c (actions_output, output_parser)
6260 (output_master_parser): To a file instead of an obstack.
6262 2001-12-15 Akim Demaille <akim@epita.fr>
6264 Attach actions to rules, instead of pre-outputting them to
6267 * src/gram.h (rule_t): action and action_line are new members.
6268 * src/reader.c (symbol_list): Likewise.
6269 (copy_action): Save the actions within the rule.
6270 (packgram): Save them in rule_table.
6271 * src/output.c (actions_output): New.
6272 (output_parser): Use it on `%%actions'.
6273 (output_rule_data): Don't free rule_table.
6275 (prepare): Don't save the `action' muscle.
6276 * src/bison.simple: s/%%action/%%actions/.
6278 2001-12-15 Akim Demaille <akim@epita.fr>
6280 * src/reader.c (copy_action): When --yacc, don't append a `;'
6281 to the user action: let it fail if lacking.
6282 Suggested by Arnold Robbins and Tom Tromey.
6284 2001-12-14 Akim Demaille <akim@epita.fr>
6286 * src/lex.c (literalchar): Simply return the char you decoded, non
6287 longer mess around with obstacks and int pointers.
6290 2001-12-14 Akim Demaille <akim@epita.fr>
6292 * src/lex.c (literalchar): Don't escape the special characters,
6293 just decode them, and keep them as char (before, eol was output as
6294 the 2 char string `\n' etc.).
6295 * src/output.c (output_rule_data): Use quotearg to output the
6298 2001-12-13 Paul Eggert <eggert@twinsun.com>
6300 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
6301 Do not infringe on the global user namespace when using C++.
6302 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
6303 All uses of `fprintf' and `stderr' changed.
6305 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
6307 2001-12-13 Akim Demaille <akim@epita.fr>
6309 The computation of nullable is broken: it doesn't handle empty
6312 * tests/torture.at (GNU AWK Grammar): New.
6313 * tests/sets.at (Nullable): New.
6314 * src/nullable.c (set_nullable): Instead of blindly looping over
6315 `ritems', loop over the rules, and then over their rhs's.
6317 Work around Autotest bugs.
6319 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
6320 frame, because Autotest understand lines starting with a `+' as
6321 traces from the shell. Then, they are not processed properly.
6322 Admittedly an Autotest bug, but we don't have time to wait for
6323 Autotest to catch up.
6324 * tests/regression.at (Broken Closure): Adjust to the new table
6327 * tests/sets.at: here.
6329 2001-12-13 Akim Demaille <akim@epita.fr>
6331 * src/closure.c (closure): Use nrules instead of playing tricks
6334 2001-12-13 Akim Demaille <akim@epita.fr>
6336 * src/print.c (print_actions): Output the handling of `$' as the
6337 traces do: shifting the token EOF. Before EOF was treated as a
6339 * tests/regression.at: Adjust some tests.
6340 * src/print_graph.c (print_core): Complete the set of items via
6341 closure. The next-to-final and final states are still unsatisfying,
6342 but that's to be addressed elsewhere.
6343 No longer output the rule numbers, but do output the state number.
6344 A single loop for the shifts + gotos is enough, but picked a
6345 distinct color for each.
6346 (print_graph): Initialize and finalize closure.
6348 2001-12-13 Akim Demaille <akim@epita.fr>
6350 * src/reader.c (readgram): Remove dead code, an strip useless
6352 (get_type): Remove, unused.
6354 2001-12-12 Akim Demaille <akim@epita.fr>
6356 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
6357 on that of lib/error.c.
6359 2001-12-12 Akim Demaille <akim@epita.fr>
6361 Some hosts don't like `/' in includes.
6363 * src/system.h: Include libgettext.h without qualifying the path.
6364 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
6367 2001-12-11 Marc Autret <autret_m@epita.fr>
6369 * src/output.c (output_parser): Remove useless muscle.
6371 2001-12-11 Marc Autret <autret_m@epita.fr>
6373 * src/bison.simple: Remove #line just before %%epilogue. It
6374 is now handled in ...
6375 * src/reader.c (read_additionnal_code): Add the output of a
6376 #line for the epilogue.
6378 2001-12-10 Marc Autret <autret_m@epita.fr>
6380 * src/reader.c (copy_definition): Re-use CPP-outed code which
6381 replace precedent remove.
6382 * src/bison.simple: Remove #line before %%prologue because
6383 %%input-line is wrong at this time.
6385 2001-12-10 Marc Autret <autret_m@epita.fr>
6387 * src/reader.c (symbols_output): Clean up.
6388 * src/output.c (output_gram, output): Clean up.
6390 2001-12-10 Akim Demaille <akim@epita.fr>
6392 * src/lalr.c (initialize_lookaheads): New. Extracted from...
6393 * src/LR0.c (set_state_table): here.
6394 * src/lalr.c (lalr): Call it.
6396 2001-12-10 Akim Demaille <akim@epita.fr>
6398 * src/state.h (shifts): Remove the `number' member: shifts are
6399 attached to state, hence no longer need to be labelled with a
6402 2001-12-10 Akim Demaille <akim@epita.fr>
6404 Now that states have a complete set of members, the linked list of
6405 shifts is useless: just fill directly the state's shifts member.
6407 * src/state.h (shifts): Remove the `next' member.
6408 * src/LR0.c (first_state, last_state): Remove.
6410 (augment_automaton): Don't look for the shifts that must be added
6411 a shift on EOF: it is those of the state we looked for! But now,
6412 since shifts are attached, it is no longer needed to looking
6413 merely by its id: its number.
6415 2001-12-10 Akim Demaille <akim@epita.fr>
6417 * src/LR0.c (augment_automaton): Better variable locality.
6418 Remove an impossible branch: if there is a state corresponding to
6419 the start symbol being shifted, then there is shift for the start
6420 symbol from the initial state.
6422 2001-12-10 Akim Demaille <akim@epita.fr>
6424 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
6425 only when appropriate: when insert_start_shifting_state' is not
6427 * tests/regression.at (Rule Line Numbers): Adjust.
6429 2001-12-10 Akim Demaille <akim@epita.fr>
6431 * src/LR0.c (augment_automaton): Now that all states have shifts,
6432 merge the two cases addition shifts to the initial state.
6434 2001-12-10 Akim Demaille <akim@epita.fr>
6436 * src/lalr.c (set_state_table): Move to...
6438 * src/lalr.c (lalr): Don't call it...
6439 * src/LR0.c (generate_states): do it.
6440 * src/LR0.h (first_state): Remove, only the table is used.
6442 2001-12-10 Akim Demaille <akim@epita.fr>
6444 * src/LR0.h (first_shift, first_reduction): Remove.
6445 * src/lalr.c: Don't use first_shift: find shifts through the
6448 2001-12-10 Akim Demaille <akim@epita.fr>
6450 * src/LR0.c: Attach shifts to states as soon as they are
6452 * src/lalr.c (set_state_table): Instead of assigning shifts to
6453 state, just assert that the mapping was properly done.
6455 2001-12-10 Akim Demaille <akim@epita.fr>
6457 * src/LR0.c (insert_start_shift): Rename as...
6458 (insert_start_shifting_state): this.
6459 (insert_eof_shifting_state, insert_accepting_state): New.
6460 (augment_automaton): Adjust.
6461 Better locality of the variables.
6462 When looking if the start_symbol is shifted from the initial
6463 state, using `while (... symbol != start_symbol ...)' sounds
6464 better than `while (... symbol < start_symbol ...)': If fail
6465 to see how the order between symbols could be relevant!
6467 2001-12-10 Akim Demaille <akim@epita.fr>
6469 * src/getargs.h: Don't declare `spec_name_prefix' and
6470 `spec_file_prefix', declared by src/files.h.
6471 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".

6473 * src/output.c (prepare): Adjust.
6474 * src/reader.c (symbols_output): Likewise.

6477 2001-12-10 Akim Demaille <akim@epita.fr>
6479 * src/muscle_tab.c (muscle_init): NULL is a better default than
6482 2001-12-10 Akim Demaille <akim@epita.fr>
6484 * src/reader.c (reader): Calling symbols_output once is enough.
6486 2001-12-10 Akim Demaille <akim@epita.fr>
6488 Now that states have a complete set of members, the linked list of
6489 reductions is useless: just fill directly the state's reductions
6492 * src/state.h (struct reductions): Remove member `number' and
6494 * src/LR0.c (first_reduction, last_reduction): Remove.
6495 (save_reductions): Don't link the new reductions, store them in
6497 * src/lalr.c (set_state_table): No need to attach reductions to
6498 states, it's already done.
6499 * src/output.c (output_actions): No longer free the shifts, then
6500 the reductions, then the states: free all the states and their
6503 2001-12-10 Akim Demaille <akim@epita.fr>
6505 * src/options.c (OPTN, DRTV, BOTH): New.
6506 (option_table): Use them.
6508 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
6509 the job of system.h.
6510 * src/options.c: Don't include stdio.h and xalloc.h for the same
6513 2001-12-10 Akim Demaille <akim@epita.fr>
6515 * src/output.c (output, prepare): Make sure the values of the
6516 muscles `action' and `prologue' are 0-terminated.
6518 2001-12-10 Akim Demaille <akim@epita.fr>
6520 Clean up GCC warnings.

6533 M4 is not needed, but AUTOM4TE is.
6535 * tests/Makefile.am: Adjust.
6537 2001-12-10 Akim Demaille <akim@epita.fr>
6539 One structure for states is enough, even though theoretically
6540 there are LR(0) states and LALR(1) states.
6542 * src/lalr.h (state_t): Remove.
6543 (state_table): Be state_t **, not state_t *.
6544 * src/state.h (core, CORE_ALLOC): Rename as...
6545 (state_t, STATE_ALLOC): this.
6546 Add the LALR(1) members: shifts, reductions, errs.
6547 * src/LR0.c (state_table): Rename as...
6548 (state_hash): this, to avoid name clashes with the global
6550 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
6551 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
6553 2001-12-10 Akim Demaille <akim@epita.fr>
6555 Bison dumps core on bash.y.
6556 Reported by Pascal Bart.
6558 * src/warshall.c (bitmatrix_print): New.
6560 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
6561 j must be the outer loop.
6562 * tests/regression.at (Broken Closure): New.
6564 2001-12-05 Akim Demaille <akim@epita.fr>
6566 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
6568 Reported by Peter Hámorský.

6573 (resolve_sr_conflict): Adjust.
6574 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
6576 (state_t.reductions, state_t.shifts): this.
6578 2001-12-05 Akim Demaille <akim@epita.fr>
6580 * src/reduce.c (reduce_grammar_tables): No longer disable the
6581 removal of useless rules via CPP but via `if (0)', so that the
6582 compiler still check the code is valid.
6583 For instance, it should have noticed `rline' no longer exists: use
6584 the `line' member of rule_t.
6585 * src/gram.c (dummy, rline): Remove, unused.
6587 2001-12-05 Akim Demaille <akim@epita.fr>
6589 * src/output.c (pack_vector): Use assert, not berror.
6590 * src/main.c (berror): Remove, unused.
6592 2001-12-05 Akim Demaille <akim@epita.fr>
6594 New experimental feature: if --verbose --trace output all the
6595 items of a state, not only its kernel.
6597 * src/print.c (print_core): If `trace_flag', then invoke closure
6598 before outputting the items of the state (print_core is no longer
6599 a correct name them).
6600 (print_results): Invoke new_closure/free_closure if needed.
6602 2001-12-05 Akim Demaille <akim@epita.fr>
6604 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
6605 * src/closure.c, src/closure.h (itemsetsize): Rename as...

6608 2001-12-05 Akim Demaille <akim@epita.fr>
6610 * src/closure.c (print_closure): Improve.
6611 (closure): Use it for printing input and output.
6613 2001-12-05 Akim Demaille <akim@epita.fr>
6615 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
6616 indexed by nonterminals.
6618 2001-12-05 Akim Demaille <akim@epita.fr>
6620 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

6638 * src/output.c (action_row): De-obfuscate
6639 using the good o' techniques: arrays not pointers, variable
6640 locality, BITISSET, RESETBIT etc.
6642 2001-12-05 Akim Demaille <akim@epita.fr>
6644 Pessimize the code to simplify it: from now on, all the states
6645 have a valid SHIFTS, which NSHIFTS is possibly 0.
6647 * src/LR0.c (shifts_new): Be global and move to..
6648 * src/state.c, src/state.h: here.
6649 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
6650 * src/print_graph: Adjust.
6652 2001-12-05 Akim Demaille <akim@epita.fr>
6654 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
6655 * src/conflicts.c: Use it.
6656 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
6657 incorrectly ``simplified''.
6659 2001-12-05 Akim Demaille <akim@epita.fr>
6661 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
6662 using the good o' techniques: arrays not pointers, variable

6667 * src/state.h (SHIFT_SYMBOL): New.
6668 * src/conflicts.c: Use it to deobfuscate.

6672 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
6673 (print_reductions): De-obfuscate using the good o' techniques:

6711 Use arrays instead of pointers.
6713 2001-12-05 Akim Demaille <akim@epita.fr>
6715 * src/lalr.c (maxrhs): Move to...
6716 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
6717 * src/lalr.c (build_relations): Adjust.
6719 2001-12-05 Akim Demaille <akim@epita.fr>
6721 * src/lalr.c (transpose): Free the memory allocated to the
6722 argument, as it is replaced by the results by the unique caller.
6723 (build_relations): Merely invoke transpose: it handles the memory
6725 Improve variable locality.
6726 Avoid variables used as mere abbreviations.
6727 (compute_lookaheads): Use arrays instead of pointers.
6729 2001-12-05 Akim Demaille <akim@epita.fr>
6731 * src/lalr.c (initialize_F): Improve variable locality.

6736 * src/derives.c (print_derives): Display the ruleno.
6737 * src/lalr.c (initialize_F, transpose): Better variable locality
6738 to improve readability.
6739 Avoid variables used as mere abbreviations.
6741 2001-12-05 Akim Demaille <akim@epita.fr>
6743 * src/lalr.c (traverse): Use arrays instead of pointers.
6745 2001-12-05 Akim Demaille <akim@epita.fr>
6747 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
6748 the handling of squeue.
6749 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
6751 2001-12-05 Akim Demaille <akim@epita.fr>
6753 Because useless nonterminals are now kept alive (instead of being
6754 `destroyed'), we now sometimes examine them, and store information
6755 related to them. Hence we need to know their number, and adjust
6758 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
6760 * src/LR0.c (allocate_itemsets): The memory allocated to
6761 `symbol_count' was used for two different purpose: once to count
6762 the number of occurrences of each symbol, and later reassigned to
6763 `shift_symbol', containing the symbol that can be shifted from a
6765 Deobfuscate, i.e., allocate, use and free `symbol_count' here
6767 (new_itemsets): Allocate `shift_symbol' here.
6768 (allocate_itemsets): symbol_count includes useless nonterminals.
6770 (free_storage): Use `free', not `XFREE', for pointers that cannot
6773 2001-12-05 Akim Demaille <akim@epita.fr>
6775 * src/nullable.c (set_nullable): Deobfuscate the handling of
6777 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
6779 2001-12-05 Akim Demaille <akim@epita.fr>
6781 * src/gram.c, src/gram.h (ritem_print): New.
6782 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
6783 (This useless function was defined only to work around VMS linkers
6784 that can't handle compilation units with variables only).
6785 * src/reduce.c (dump_grammar): Use it to trace the construction of
6788 2001-12-04 Paul Eggert <eggert@twinsun.com>
6790 * src/bison.simple (union yyalloc): Change member names
6791 to be the same as the stack names.
6792 (yyparse): yyptr is now union yyalloc *, not char *.
6793 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
6794 and may generate better code on some machines.
6795 (yystpcpy): Use prototype if __STDC__ is defined, not just
6796 if __cplusplus is defined.
6798 2001-11-30 Akim Demaille <akim@epita.fr>
6800 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
6801 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
6802 Gettext doesn't compile cleanly, and dies with -Werror.
6803 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
6804 Include WARNING_CFLAGS here.
6805 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
6806 before being defined.

6810 * lib/quotearg.h (quotearg_n, quotearg_n_style):
6811 First arg is int, not unsigned.
6812 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
6813 (SIZE_MAX, UINT_MAX): New macros.
6814 (quotearg_n_options): Abort if N is negative.
6815 Avoid overflow check on hosts where size_t is 64 bits and int
6816 is 32 bits, as overflow is impossible there.
6817 Fix off-by-one typo that caused unnecessary reallocation.
6819 2001-11-29 Paul Eggert <eggert@twinsun.com>
6821 Name space cleanup in generated parser.
6823 * doc/bison.texinfo (Bison Parser): Discuss system headers
6824 and their effect on the user name space.
6827 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
6828 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
6829 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
6831 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
6832 on user names when possible.
6834 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
6835 Simplify test for whather <alloca.h> exists.
6837 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
6839 (<stdio.h>): Include if YYDEBUG.
6841 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
6842 ! defined (yyoverflow) && ! defined (yymemcpy).
6844 (yymemcpy, yyparse): Rename local variables as needed so that
6845 they all begin with 'yy'.
6847 (yystrlen, yystpcpy): New functions.
6849 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
6852 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
6853 instead of relying on string.h functions. Use YYSTACK_ALLOC
6854 and YYSTACK_FREE instead of malloc and free.
6856 2001-11-30 Akim Demaille <akim@epita.fr>
6858 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
6859 before their first uses.
6860 (YYBISON, YYPURE): Move to the top of the output.
6862 2001-11-30 Akim Demaille <akim@epita.fr>
6864 * tests/reduce.at (Useless Nonterminals): Fix.
6866 2001-11-30 Akim Demaille <akim@epita.fr>
6868 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
6869 if body instead of `;' to pacify GCC's warnings.
6871 2001-11-30 Akim Demaille <akim@epita.fr>
6873 Instead of mapping the LHS of unused rules to -1, keep the LHS
6874 valid, but flag the rules as invalid.
6876 * src/gram.h (rule_t): `useful' is a new member.
6877 * src/print.c (print_grammar): Adjust.
6878 * src/derives.c (set_derives): Likewise.
6879 * src/reader.c (packgram, reduce_output): Likewise.
6880 * src/reduce.c (reduce_grammar_tables): Likewise.
6881 * tests/reduce.at (Underivable Rules, Useless Rules): New.
6883 2001-11-30 Akim Demaille <akim@epita.fr>
6885 * src/reduce.c (reduce_output): Formatting changes.
6886 * src/print.c (print_results, print_grammar): Likewise.
6887 * tests/regression.at (Rule Line Numbers)
6888 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
6890 2001-11-30 Akim Demaille <akim@epita.fr>
6892 * src/reduce.c (nonterminals_reduce): Instead of throwing away
6893 useless nonterminals, move them at the end of the symbol arrays.
6894 (reduce_output): Adjust.
6895 * tests/reduce.at (Useless Nonterminals): Adjust.
6897 2001-11-30 Akim Demaille <akim@epita.fr>
6899 * src/reduce.c: Various comment/formatting changes.

6906 * src/bison.simple (YYSTACK_REALLOC): Remove.
6907 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
6908 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
6910 (union yyalloc): New type.
6911 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
6912 an arbitrary restriction on hosts where size_t is wider than int.
6914 (yyparse): Don't dump core if alloca or malloc fails; instead, report
6915 a parser stack overflow. Allocate just one block of memory for all
6916 three stacks, instead of allocating three blocks; this typically is
6917 faster and reduces fragmentation.
6919 Do not limit the number of items in the stack to a value that fits
6920 in 'int', as this is an arbitrary limit on hosts with 64-bit
6921 size_t and 32-bit int.
6923 2001-11-29 Marc Autret <autret_m@epita.fr>
6925 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
6926 of defining YYERROR_VERBOSE.

6936 2001-11-28 Marc Autret <autret_m@epita.fr>
6938 * src/output.h: And put its extern declaration here.
6939 * src/output.c (error_verbose): Define here.
6940 (prepare): Echo name modification.
6941 * src/getargs.h: Clean its extern declaration.
6942 * src/getargs.c (error_verbose_flag): Remove.
6943 (getargs): Remove case 'e'.
6944 * src/options.c (option_table): 'error-verbose' is now seen as simple
6948 * src/reader.c (read_declarations): Remove case tok_include.
6949 (parse_include_decl): Remove.
6950 * src/lex.h (token_t): Remove tok_include.

6971 2001-11-28 Akim Demaille <akim@epita.fr>
6973 * src/closure.c (closure): `b' and `ruleno' denote the same value:
6976 2001-11-28 Akim Demaille <akim@epita.fr>
6978 * src/closure.c (closure): Instead of looping over word in array
6979 then bits in words, loop over bits in array.
6981 2001-11-28 Akim Demaille <akim@epita.fr>
6983 * src/closure.c (closure): No longer optimize the special case
6984 where all the bits of `ruleset[r]' are set to 0, to make the code
6987 2001-11-28 Akim Demaille <akim@epita.fr>
6989 * src/closure.c (closure): `r' and `c' are new variables, used to
6990 de-obfuscate accesses to RULESET and CORE.
6992 2001-11-28 Akim Demaille <akim@epita.fr>
6994 * src/reduce.c (reduce_print): Use ngettext.

8726 * src/conflicts.c (conflict_report): Be sure not to append to res
8727 between two calls, which could happen if both first sprintf were

8733 New, from fileutils 4.0.37.
8734 * configure.in: Require Autoconf 2.49c. I took some time before
8735 making this decision. This is the only way out for portability
8736 issues in Bison, it would mean way too much duplicate effort to
8737 import in Bison features implemented in 2.49c since 2.13.
8738 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

8779 * src/reader.c (read_declarations): Adjust.
8780 * src/files.c (open_files): Don't call `compute_base_names', don't

8784 * src/output.c (output_headers): Document the fact that this patch
8785 introduces a guaranteed SEGV for semantic parsers.

8862 * src/output.c (output_parser): Compute the `#line' lines when
8864 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
8865 Suggested by Hans Aberg.
8867 2000-12-19 Akim Demaille <akim@epita.fr>

8923 prevents type checking.
8924 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
8925 cast the value to (void *): assigning a `foo *' to a `void *'

8928 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

8940 * tests/regression.m4 (%union and --defines): New test,
8941 demonstrating a current bug in the obstack implementation.

9005 (done): Rename as...
9006 (output_files): this.
9008 * src/main.c (main): Don't use `atexit' to register `done', since
9009 it no longer has to remove tmp files, just call `output_files'
9010 when there are no errors.
9012 2000-11-02 Akim Demaille <akim@epita.fr>
9014 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
9015 `unlink': it's no longer used.
9016 * src/files.h: Formatting changes.
9018 2000-11-02 Akim Demaille <akim@epita.fr>

9083 called after `//' or `/*' was read.
9084 (copy_comment, copy_definition, parse_union_decl, copy_action)
9085 (copy_guard): Adjust.
9087 2000-10-16 Akim Demaille <akim@epita.fr>

9113 2000-10-04 Akim Demaille <akim@epita.fr>
9115 When a literal string is used to define two different tokens,
9116 `bison -v' segfaults.
9117 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
9119 * tests/regression.m4: New file.
9120 Include the core of the sample provided by Piotr Gackiewicz.
9121 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
9124 2000-10-04 Akim Demaille <akim@epita.fr>

9144 translation, move some `\n' out of the translated strings.
9146 2000-10-02 Akim Demaille <akim@epita.fr>
9148 The location tracking mechanism is precious for parse error
9149 messages. Nevertheless, it is enabled only when `@n' is used in
9150 the grammar, which is a different issue (you can use it in error
9151 message, but not in the grammar per se). Therefore, there should
9152 be another means to enable it.
9154 * src/getargs.c (getargs): Support `--locations'.
9156 * src/getargs.h (locationsflag): Export it.
9157 * src/lex.c (percent_table): Support `%locations'.

9165 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
9166 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
9167 In addition replace each `flag' with `_flag'.
9169 2000-10-02 Akim Demaille <akim@epita.fr>

9182 2000-10-02 Akim Demaille <akim@epita.fr>
9184 Test also `--verbose', `--defines' and `--name-prefix'. Testing
9185 the latter demonstrates a flaw in the handling of non debugging
9186 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
9187 was used in order to simplify:
9203 unfortunately this leads to a CPP conflict when
9204 `--name-prefix=foo' is used since it produces `#define yydebug
9207 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
9208 (YYDPRINTF): New macro.
9210 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
9212 Also test `--verbose', `--defines' and `--name-prefix'.
9214 2000-10-02 Akim Demaille <akim@epita.fr>
9216 Improve the readability of the produced parsers.
9218 * src/bison.s1: Formatting changes.
9219 Improve the comment related to the `$' mark.
9220 (yydefault): Don't fall through to `yyresume': `goto' there.
9221 * src/output.c (output_parser): When the `$' is met, skip the end
9223 New variable, `number_of_dollar_signs', to check there's exactly
9224 one `$' in the parser skeleton.
9226 2000-10-02 Akim Demaille <akim@epita.fr>
9228 * lib/xstrdup.c: New file, from the fileutils.
9229 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
9230 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
9231 instead of strlen + xmalloc + strcpy.
9232 * src/symtab.c (copys): Remove, use xstrdup instead.
9234 2000-10-02 Akim Demaille <akim@epita.fr>
9236 * src/gram.h (associativity): New enum type which replaces the
9237 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
9238 `right_assoc', `left_assoc' and `non_assoc'.
9239 Adjust all dependencies.
9240 * src/reader.c: Formatting changes.

9244 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

9250 (yaccflag): for consistency and accuracy.
9251 Adjust dependencies.
9253 2000-10-02 Akim Demaille <akim@epita.fr>
9255 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
9256 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
9257 difficult and introduced a lot of core dump. It turns out that
9258 Bison used an implementation of `xmalloc' based on `calloc', and
9259 at various places it does depend upon the initialization to 0. I
9260 have not tried to isolate the pertinent places, and all the former
9261 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
9262 someone should address this issue.
9264 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

9363 2000-10-02 Akim Demaille <akim@epita.fr>
9365 `user_toknums' is output as a `short[]' in `output.c', while it is
9366 defined as a `int[]' in `reader.c'. For consistency with the
9367 other output tables, `user_toknums' is now defined as a table of

9411 * src/system.h: Define PARAMS.
9412 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

9630 2000-03-17 Akim Demaille <akim@epita.fr>
9632 Change the handling of @s so that they behave exactly like $s.
9633 There is now a pseudo variable @$ (readble and writable), location
9634 of the lhs of the rule (by default ranging from the location of
9635 the first symbol of the rhs, to the location of the last symbol,
9636 or, if the rhs is empty, YYLLOC).
9638 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
9640 (yyparse): When providing a default semantic action, provide a
9641 default location action.
9642 (after the $): No longer change `*YYLSP', just stack YYLOC the
9643 same way you stack YYVAL.
9644 * src/reader.c (read_declarations): Use warns.
9645 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

9671 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
9672 One `#if YYDEBUG' remains, since it uses variables which are
9673 defined only if `YYDEBUG != 0'.
9675 2000-03-16 Akim Demaille <akim@epita.fr>
9677 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

9697 Bump to bison 1.28a, 1.29 has never been released.
9698 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
9699 handled via src/Makefile.am.

10360 (get_type, packsymbols): Revised most error messages.
10361 Changed `fatal' to `warnxxx' to avoid aborting for error.
10362 Revised and use multiple warnxxx functions to avoid using VARARGS1.
10363 (read_declarations): Improve the error message for
10364 an invalid character. Do not abort.
10365 (read_declarations, copy_guard, copy_action): Use
10366 printable_version to avoid unprintable characters in printed output.
10367 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
10368 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
10369 Allow the type of a non-terminal can be given
10370 more than once, as long as all specifications give the same type.
10373 (output_headers, output_trailers, output, output_gram)
10374 (output_rule_data): Implement noparserflag variable.
10375 Implement toknumflag variable.

10398 (parse_percent_token): Added % declarations as another
10399 way to specify the flags -n, -l, and -r. Also added hooks for
10400 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
10401 major changes to files.c.
10402 (lex) Retain in the incoming stream a character following
