233 (Actions): Mention look-ahead usage of yylval.
234 (Actions and Locations): Mention look-ahead usage of yylloc.
235 (Special Features for Use in Actions): Add YYEOF entry and mention it
236 in the yychar entry.
237 In the yychar entry, remove mention of the local yychar case (pure
238 parser) since this is irrelevant information when writing semantic
239 actions and since it's already discussed in `Bison Symbols' where
240 yychar is otherwise described as an external variable.
241 In the yychar entry, don't call it the `current' look-ahead since it
242 isn't when semantic actions are deferred.
243 In the yychar and yyclearin entries, add note about deferred semantic
244 actions.
245 Add yylloc and yylval entries discussing look-ahead usage.
246 (Look-Ahead Tokens): When discussing yychar, don't call it the
247 `current' look-ahead, and do mention yylval and yylloc.
248 (Error Recovery): Cross-reference `Action Features' when mentioning
249 yyclearin.
250 (Bison Symbols): In the yychar entry, don't call it the `current'
251 look-ahead.

256 * tests/glr-regression.at: Update copyright year to 2006.
258 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
260 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
261 use during nondeterministic operation to track which stacks have
262 actually needed the current lookahead.
263 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
264 Allocate, deallocate, resize, and otherwise shuffle space for
265 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
266 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
267 appropriately during nondeterministic operation.
268 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
269 members to store the current lookahead to be used by the deferred
270 user action.
271 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
272 from which the RHS is taken. Set the lookahead members of the new
273 yySemanticOption according to the lookahead status for stack yyk.
274 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
275 yyaddDeferredAction.
276 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
277 members of yySemanticOption before invoking yyuserAction, and then set
278 them back to their current values afterward.
279 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
280 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
281 * tests/glr-regression.at: Remove `.' from the ends of recent test case
282 titles for consistency.
283 (Leaked merged semantic value if user action cuts parse): In order to
284 suppress lint warnings, use arguments in merge function, and assign
285 char value < 128 in main.
286 (Incorrect lookahead during deterministic GLR): New test case.
287 (Incorrect lookahead during nondeterministic GLR): New test case.
289 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
291 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
292 !yyvaluep as signal that no semantic value is available to print.
293 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
294 to print a semantic value.
296 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
298 * tests/glr-regression.at: For consistency with my newer test cases,
299 don't thank myself.
301 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
303 * data/glr.c (yyresolveValue): When merging semantic options, if at
304 least one user action succeeds but a later one cuts the parse, then
305 destroy the semantic value before returning rather than leaking it.
306 (yyresolveStates): If a user action cuts the parse and thus
307 yyresolveValue fails, ignore the (unset) semantic value rather than
308 corrupting the yyGLRState, and empty the semantic options list since
309 the user actions should have called all necessary destructors.
310 Simplify code with YYCHK.
311 * tests/glr-regression.at (Corrupted semantic options if user action
312 cuts parse): New test case.
313 (Undesirable destructors if user action cuts parse): New test case.
314 Before applying any of this patch, this test case never actually failed
315 for me... but only because the corrupted semantic options usually
316 masked this bug.
317 (Leaked merged semantic value if user action cuts parse): New test
318 case.
320 2006-01-05 Akim Demaille <akim@epita.fr>
322 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

331 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
332 than rolling our own.

351 mid-rule, move the `used' bit to its lhs.
352 * tests/input.at (Unused values): New.
353 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
355 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
357 * doc/bison.texinfo (Bison Options): Say more accurately what
358 --yacc does.
359 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
360 about declarations in the grammar when in Yacc mode, as POSIX does
361 not require a diagnostic when the grammar uses extensions.
363 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
365 Warn about dubious constructions like "%token T T".
366 Reported by twlevo.
367 * src/symtab.h (struct symbol.declared): New member.
368 * src/symtab.c (symbol_new): Initialize it to false.
369 (symbol_class_set): New arg DECLARING, specifying whether
370 this is a declaration that we want to warn about, if there
371 is more than one of them. All uses changed.
373 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
374 Allow multiple %union directives, whose contents concatenate.
375 * src/parse-gram.y (grammar_declaration): Likewise.
376 Use muscle_code_grow, so that we don't need stype_line any more.
377 All uses changed.
379 * src/muscle_tab.c (muscle_grow): Fix comment.
381 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:

389 (b4_parse_param): Improve its definition, and bound it more
390 clearly in the skeleton.
391 (b4_epilogue): Append, instead of prepending, in order to keep
392 #line consistency.
393 Simplify the generation of auxiliary functions: locations and
394 purity are mandated.
395 (b4_global_tokens_and_yystype): Honor it.
396 * data/location.cc (c++.m4): Don't include it.
397 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
398 and AT_SKEL_CC_IF.
399 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
400 AT_LALR1_CC_IF.
401 Be sure to initialize the first position's filename.
402 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
403 mandated anyway.
404 (AT_CHECK_CALC_GLR_CC): New.
405 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
407 2006-01-02 Akim Demaille <akim@epita.fr>
409 * src/output.c (output_skeleton): Don't hard wire the inclusion of
410 c.m4.
411 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.
412 * data/glr.cc: Do not include stack.hh.

424 Let glr.cc catch up with symbol_value_print.
425 * data/glr.cc (b4_yysymprint_generate): Replace by...

429 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>

469 YYERROR or other.
470 * tests/actions.at (Exotic Dollars): Instead of using unused
471 values, check that the warning is issued.

510 Undo 2005-12-01 tentative license wording change. The wording is
511 still being reviewed by the lawyers, and we don't want to wait for
512 them before publishing a test release. For now, revert to the
513 previous wording.
514 * NEWS: Undo 2005-12-01 change.
515 * data/glr.c: Revert to previous license wording.

529 text slightly.
530 * tests/cxx-type.at: Cast results of malloc, for C++.
532 2005-12-21 Joel E. Denny <address@hidden>
534 * tests/cxx-type.at: Construct a tree, count the parents of shared
535 nodes, and free each node once and only once. Previously, the memory
536 for semantic values was leaked instead.
538 2005-12-21 Joel E. Denny <address@hidden>
540 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
541 (yylval, yylloc): If pure, #define to yystackp->yyval and
542 yystackp->yyloc similar to yychar and yynerrs.
543 (yyparse): If pure, remove local yylval and yylloc. Add local
544 yystackp to accommodate pure definitions of yylval and yylloc.

546 yylvalp and yyllocp to &yylval and &yylloc.

551 yylvalp and yyllocp parameters since, if pure, these are now always
552 accessible through yystackp. If not pure, they are still accessible

560 destroy the RHS symbols of a rule.
561 * data/yacc.c (yylen): Initialize to 0.

563 In particular, a regular successful parse that ends on YYFINAL by
564 a (internal) YYACCEPT must not have yylen != 0.
565 (yyerrorlab, yyreturn): Pop the RHS.
566 Reorder a bit to emphasize the `shifting' bits of code.
567 (YYPOPSTACK): Now accept a number of items to pop.

579 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
580 * djgpp/config.sed: Replace every occurence of the file name
581 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
582 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
583 * djgpp/djunpack.bat: DJGPP specific file.
584 * djgpp/fnchange.lst: DJGPP specific file.

610 * tests/sets.at (Accept): Fix typos in regular expression used to
611 sed out the final state number.
613 Work around portability problem on Solaris 10: flex-generated
614 files include <stdio.h> before <config.h>, which messes up
615 because the latter defines __EXTENSIONS__. Address the problem
616 by creating two new little files that include <config.h> first,
617 then include the flex-generated files. Rewrite everyone else
618 to include <config.h> first, as well.
619 * lib/timevar.c: Always include "config.h".
620 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

661 definition if 'lint' is defined.
662 (YYID): New macro (or function, if lint).
663 All uses of /*CONSTCOND*/0 replaced by YYID(0).
664 * data/yacc.c: Likewise.
665 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
666 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
667 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
668 is C++ only.
669 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
670 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
671 Use YYID(0) rather than 0, for lint.
672 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
673 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

689 to succeed.
691 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
693 * NEWS: Document the following change.
694 * data/yacc.c: Say "parser skeleton" rather than "file", since
695 it's no longer just a file.
696 * data/glr.c: Grant a special exception for C GLR parsers, that
697 reads like the already-existing exception for C LALR(1) parsers.
698 * data/glr.cc: Likewise.
699 * data/lalr1.cc: Likewise.
700 * data/location.cc: Likewise.
701 * data/yacc.c: Reword the "written by" statement to clarify that
702 it was the parser skeleton, not the entire output file.

709 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
710 Fix typos in previous change that broke 'make check'.

712 supported in C.
713 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
714 Don't check NUM-STDERR-LINES, since the output format is fluctuating.

791 Have glr.c include its header file when created.
792 * data/glr.c (b4_shared_declarations): New.

955 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
956 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
958 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
960 Undo the parts of the unlocked-I/O change that substituted
961 putc or puts for printf. This might hurt performance a bit,
962 but some people prefer the printf style.
963 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
964 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
965 All uses replaced by YYFPRINTF and YYDPRINTF.
966 * data/yacc.c: Likewise.
967 * lib/bitset.c (bitset_print): Likewise.

981 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
982 Use assignments rather than casts-to-void to suppress
983 unused-variable warnings. This pacifies 'lint'.
984 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
985 unused-variable warnings.
987 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
989 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
991 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
993 Use unlocked I/O for a minor performance improvement on hosts like
994 GNU/Linux and Solaris that support unlocked I/O. The basic idea
995 is to use the gnlib unlocked-io module, and to prefer putc and
996 puts to printf when either will work (since the latter doesn't
997 come in an unlocked flavor).
998 * bootstrap (gnulib_modules): Add unlocked-io.
999 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
1000 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

1007 to printf.
1008 * lib/lbitset.c (debug_lbitset): Likewise.
1009 * src/closure.c (print_firsts, print_fderives): Likewise.
1010 * src/gram.c (grammar_dump): Likewise.
1011 * src/lalr.c (look_ahead_tokens_print): Likewise.
1012 * src/output.c (escaped_output): Likewise.
1013 (user_actions_output): Coalesce two printfs.

1017 * src/system.h: Include unlocked-io.h rather than stdio.h.
1019 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
1020 this confuses xgettext.

1064 * lib/subpipe.c: New function end_of_output_subpipe() added
1065 to allow support for non-posix systems. This is a no-op function
1066 for posix systems.
1068 * lib/subpipe.h: New function end_of_output_subpipe() added
1069 to allow support for non-posix systems. This is a no-op function
1070 for posix systems.
1072 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
1073 handle the lack of pipe/fork functionality on non-posix systems.
1075 * djgpp/Makefile.maint: DJGPP specific file.
1077 * djgpp/README.in: DJGPP specific file.

1102 2005-10-01 Akim Demaille <akim@epita.fr>
1104 * examples/extexi: Restore the #line generation.

1107 Alexandre Duret-Lutz <adl@gnu.org>
1109 Move the token type and YYSTYPE in the parser class.
1110 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
1111 (parser::token): New, from the moved free definition of tokens.
1112 (parser::semantic_value): Now a full definition instead of an
1113 indirection to YYSTYPE.

1156 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
1157 local variables whose names begin with 'yy'.
1158 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1159 Trivial changes from Joel E. Denny.
1161 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1162 it itself.
1163 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1164 don't use alloca any more.
1166 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1167 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
1168 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
1169 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
1170 to match yacc.c, to test more hosts.
1172 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
1174 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This

1177 Solaris, AIX, MSC.
1178 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
1179 This works a bit better with glibc, if user code has already included
1180 stdlib.h.
1181 * doc/bison.texinfo (Bison Parser): Document that users can't
1182 arbitrarily use malloc and free for other purposes. Document
1183 that <alloca.h> and <malloc.h> might be included.

1197 (YYSTACK_ALLOC_MAXIMUM): Use it.
1198 (yysyntax_error): New function.
1199 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
1200 multiple syntax errors are reported, and alloca is being used.
1201 Instead, reallocate buffers twice as big each time, so that
1202 we waste at most half the allocated memory. Start with a small
1203 (128-byte) buffer that will suffice in most cases anyway.
1204 Use yysyntax_error to do most of the work.
1206 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1207 yynerrs is the number of errors reported, not the number of
1208 errors encountered.
1210 * tests/glr-regression.at (Duplicated user destructor for lookahead):
1211 Mark it as expected to fail.
1212 Cast result of malloc; problem reported by twlevo@xs4all.nl.
1213 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
1214 Don't start user-code symbols with "yy", to avoid name space problems.
1216 2005-09-19 Akim Demaille <akim@epita.fr>
1218 Remove the traits, failed experiment.
1219 It never proved useful, and anyway because of the current
1220 definition, it was not possible to have several specialization of
1221 this traits, making it useless.
1222 * data/lalr1.cc (yy:traits): Remove.
1223 Inline its definitions in the parser class.
1225 2005-09-19 Akim Demaille <akim@epita.fr>

1246 diagnostic.
1247 * src/output.c (prepare): Likewise.
1248 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
1249 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
1250 is not defined. This is an awful hack, but it's enough for now.
1251 All callers changed.
1252 * tests/glr-regression-at (make_value): Args are const pointers now,
1253 to avoid GCC warning.
1254 (Duplicated user destructor for lookahead): New test. Currently
1255 skipped. It fails on my host but I'm not sure it'll always fail.
1257 2005-09-16 Akim Demaille <akim@epita.fr>
1259 * src/symtab.h (struct symbol): Declare the printer and destructor
1260 as const, to avoid accidental calls to free.

1273 as default values.
1275 2005-09-16 Akim Demaille <akim@epita.fr>
1277 * data/lalr1.cc (yylex_): Remove, inline its code.
1278 (yyreport_syntax_error_): Remove, replaced by...
1279 (yysyntax_error_): this which returns a string and leaves to the
1280 caller the call to the users' error function.
1281 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
1282 Move from members of the parser object...
1283 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
1284 to local variables of the parse function.
1286 2005-09-16 Akim Demaille <akim@epita.fr>
1288 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF

1301 (b4_filename_type): Renamed back from b4_file_name_type. All uses
1302 changed.
1303 (class position): file_name -> filename (reverting). All uses changed.
1305 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
1307 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1308 do anything if $@ exists. This reverts part of the 2005-07-07
1309 patch.
1311 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1313 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1314 contains obsolete information and isn't worth distributing as a
1315 separate file anyway.
1316 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1317 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

1320 value.
1322 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>

1325 Suggested by twlevo@xs4all.nl.
1327 * data/glr.c (YYCHK1): Do not assume YYE is in range.
1328 This avoids a diagnostic from gcc -Wswitch-enum.
1329 Problem reported by twlevo@xs4all.nl.
1331 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1332 standards. Use "file name" or "file" or "name", depending on
1333 the context.
1334 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1335 not to hack/foo.tab.c.
1336 (Calc++ Top Level): 2nd arg of main is not const.
1337 * data/glr.c: b4_filename -> b4_file_name.
1338 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

1362 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
1363 All uses changed. Invoke user destructor after an error during a
1364 split parse (trivial change from Joel E. Denny).
1366 * tests/glr-regression.at
1367 (User destructor after an error during a split parse): New test case.
1368 Problem reported by Joel E. Denny in:
1369 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html

1406 in yydestruct diagnostic, since it might not be an error.
1407 Problem reported by Joel Denny near end of
1408 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1409 * data/lalr1.cc (yyerturn): Likewise.
1410 * data/yacc.c (yyreturn): Likewise.
1411 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
1413 * src/files.c: Remove obsolete FIXME comment.
1415 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
1416 with the other templates, and to fix bogus run-on messages such
1417 as the one reported at the end of
1418 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1419 All callers changed to avoid the newline.
1420 (yyprocessOneStack): Output two lines rather than one, to accommodate
1421 the above change. This changes the debug output format slightly.
1423 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
1424 reported by Joel E. Denny in
1425 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
1426 (trivial change).
1427 * tests/glr-regression.at (Duplicate representation of merged trees):
1428 New test, from Joel E. Denny in:
1429 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
1430 * THANKS: Add Joel E. Denny.
1432 * configure.ac (AC_INIT): Bump to 2.0c.
1434 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
1436 * NEWS: Version 2.0b.
1438 * Makefile.am (SUBDIRS): Put examples before tests, so that
1439 "make check" doesn't finish with "All 1 tests passed".
1441 * tests/regression.at (Token definitions): Don't rely on
1442 AT_PARSER_CHECK for data that contains backslashes. It currently
1443 uses 'echo', and 'echo' isn't portable if its argument contains
1444 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1445 that the byte '\0xff' is not printable in the C locale; it is,
1446 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1447 not printable, so use '\0x81' to test.
1449 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1450 version of GCC, since the macro is used with non-GCC compilers.
1452 Fix core dump reported by Pablo De Napoli in
1453 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1454 * tests/regression.at (Invalid inputs with {}): New test.
1455 * src/parse-gram.y (token_name): Translate type before using
1456 it as an index.
1458 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1459 the user's name space. All uses changed to __attribute__
1460 ((__unused__)).
1461 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1462 Add __attribute__ ((__noreturn__)).
1464 * etc/clcommit: Remove. We weren't using it, and it failed
1465 "make maintainer-distcheck".
1466 * Makefile.maint: Merge from coreutils.
1467 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1468 (syntax-check-rules): Change list of rules as described below.
1469 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
1470 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
1471 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
1472 (sc_trailing_space): New rules.
1473 (sc_xalloc_h_in_src): Remove.
1474 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
1475 (sc_space_tab, sc_error_exit_success, sc_changelog):
1476 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
1477 (makefile-check, po-check, author_mark_check):
1478 (makefile_path_separator_check, copyright-check):
1479 Use grep -n, to make it easier to find violations.
1480 Use CVS_LIST and CVS_LIST_EXCEPT.
1481 (header_regexp, h_re): Remove.
1482 (dd_c): New macro.
1483 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
1484 (my-distcheck): Use more-modern GCC flags.
1485 (signatures, %.asc): Remove.
1486 (rel-files, announcement): Remove signatures.
1487 Restore old updating code, even though we don't use it, so
1488 that we're the same as coreutils.
1489 (alpha, beta, major): Depend on news-date-check.
1490 Make the upload commands.
1492 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
1493 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
1494 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
1495 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
1496 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
1497 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
1498 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
1499 * tests/sets.at: Likewise.
1501 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
1502 we comment out the Autoconf version number.
1503 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
1504 it's error-prone and "make maintainer-distcheck" rejects it.
1506 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
1507 Indent calls to "error" to pacify "make maintainer-distcheck",
1508 when the calls are not intended to be translated.
1509 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
1511 * src/Makefile.am (DEFS): Use +=, to pacify
1512 "make maintainer-distcheck".
1513 (bison_SOURCES): Add scan-skel.h.
1514 (sc_tight_scope): New rule, from coreutils.
1516 * src/files.c (src_extension, header_extension):
1517 Now static, not extern.
1518 * src/getargs.c (short_options): Likewise.
1519 * src/muscle_tab.c (muscle_table): Likewise.
1520 * src/parse-gram.y (current_class, current_type, current_prec):
1521 Likewise.
1522 * src/reader.c (grammar_end, previous_rule_end): Likewise.
1523 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
1524 * src/main.c (main): Cast bindtextdomain and textdomain calls to
1525 void, to avoid warning when NLS is disabled.
1526 * src/output.c: Include scan-skel.h.
1527 (scan_skel): Remove decl, since scan-skel.h does this.
1528 (output_skeleton):
1529 Indent calls to "error" to pacify "make maintainer-distcheck".
1530 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
1531 * src/reader.h (gram_end, gram_lineno): New decls to pacify
1532 "make maintainer-distcheck".
1533 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
1534 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
1535 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
1536 (skel_lex_destroy, scan_skel): Move these decls to...
1537 * src/scan-skel.h: New file.
1538 * src/uniqstr.c (uniqstr_assert):
1539 Indent calls to "error" to pacify "make maintainer-distcheck".
1541 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
1542 not @VAR@.
1544 * tests/torture.at: Revamp to avoid misuse of atoi that
1545 "make maintainer-distcheck" complained about.
1547 * examples/extexi (message): Don't print a message more than once,
1548 and omit line-number decoration that makes Emacs compile think
1549 that informative messages are worth worrying about.
1551 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
1553 * configure.ac: Update version number.
1555 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
1556 accidentally.
1557 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
1558 autogenerated by the maintainer.
1559 * examples/calc++/.cvsignore: Add *.yy.
1561 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
1562 * lib/bitset_stats.c (bitset_stats_init): Likewise.
1563 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1565 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
1567 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
1568 from maintainer-distcheck about casting the argument of 'free'.
1570 * NEWS: Mention recent yytname changes.
1571 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
1573 * bootstrap: For translations that have not yet been upgraded to
1574 the new runtime-po domain, prime the pump by extracting the
1575 relevant strings from the obsolete translations. This code can be
1576 removed once the bison-runtime domain has been translated by each
1577 team.
1579 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
1580 now that token names are already quoted.
1582 Fix problem reported by Anthony Heading.
1583 * data/glr.c (YYTOKEN_TABLE): New macro.
1584 (yytname): Define if YYTOKEN_TABLE.
1585 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
1586 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
1587 (YYERROR_VERBOSE): Define the same way the other skeletons do.
1588 * src/output.c (prepare_symbols): Output token_table_flag.
1590 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
1592 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
1593 again if the first call fails.
1595 * data/glr.c (yytnamerr): New function.
1596 (yyreportSyntaxError): Use it to dequote most string literals.
1597 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
1598 with other skeletons. All uses changed.
1599 (yytnameerr_): New function.
1600 (yyreport_syntax_error): Use it to dequote most string literals.
1601 * data/yacc.c (yytnamerr): New function.
1602 (yyerrlab): Use it to decode most string literals.
1603 * doc/bison.texinfo (Decl Summary, Calling Convention):
1604 Clarify quoting convention of yytname.
1605 * src/output.c (prepare_symbols): Quote all names. This undoes
1606 the 2005-04-17 change, which is now accomplished (mostly) via
1607 changes in the parsers as described above.
1608 * tests/regression.at (Token definitions, Web2c Actions):
1609 Undo most 2005-04-17 change here, too.
1611 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
1613 Fix more problems reported by twlevo@xs4all.nl.
1614 * tests/cxx-type.at: Don't pipe output of ./types through sed to
1615 remove trailing spaces. This loses the exit status of ./types,
1616 and isn't needed since ./types shouldn't be emitting trailing
1617 spaces.
1618 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
1619 as the stack isn't valid in that case.
1621 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
1622 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
1623 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
1624 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
1625 is used.
1626 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
1627 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
1628 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
1629 Likewise.
1631 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
1632 overly-picky compilers that reject 'char *foo = "bar";'.
1634 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
1635 to FILE * parameter, not to stderr. This fixes a typo introduced
1636 in the 2005-07-12 change.
1638 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
1639 warnings from GCC 4.
1641 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
1642 (yyglrShiftDefer, yysplitStack):
1643 Remove unused parameters b4_pure_formals. All uses changed.
1644 (yyglrShift): Remove unused parameters b4_user_formals.
1645 All uses changed.
1646 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
1648 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
1650 Destructor cleanups and regularization among the three skeletons.
1651 * NEWS: Document the behavior changes.
1652 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
1653 stack before failing, as the cleanup code will do it for us now.
1654 * data/lalr1.cc (yyerrlab): Likewise.
1655 * data/glr.c (yyparse): Pop everything off the stack before
1656 freeing it, so that destructors get called properly.
1657 * data/lalr1.cc (yyreturn): Likewise.
1658 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
1659 This is more consistent.
1660 * doc/bison.texinfo (Destructor Decl): Mention more reasons
1661 why destructors might be called. 1.875 -> 2.1.
1662 (Destructor Decl, Decl Summary, Table of Symbols):
1663 Some English-language cleanups for %destructor.
1664 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
1665 Add output line for destructor of start symbol.
1666 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
1667 because of that same extra output line.
1669 * NEWS: Document minor wording changes in diagnostics of
1670 Bison-generated parsers.
1671 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
1672 Remove unused formals. All uses changed.
1673 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
1674 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
1675 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
1676 Rename yyoverflowab to yyexhaustedlab.
1677 When memory exhaustion occurs during syntax-error reporting,
1678 report it separately rather than in a single diagnostic; this
1679 eases translation.
1680 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
1681 (Memory Exhausted): Renamed from Parser Stack Overflow.
1682 Revamp wording slightly to prefer "memory exhaustion".
1683 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
1685 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
1687 Add i18n support to the GLR skeleton. Partially fix the C++
1688 skeleton; a C++ expert needs to finish this. Remove debugging
1689 msgids; there's little point to having them translated, since they
1690 can be understood only by someone who can read the
1691 (English-language) source code.
1693 Generate runtime-po/bison-runtime.pot automatically, so that we
1694 don't have to worry about garbage getting in that file. We'll
1695 make sure after the next official release that old msgids don't
1696 get lost. See
1697 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
1699 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
1700 Now auto-generated.
1701 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
1702 Fix typos in explanations of the runtime file.
1703 * bootstrap: Change gettext keyword from YYI18N to YY_.
1704 Use standard Makefile.in.in in runtime-po, since we'll arrange
1705 for backward-compatible bison-runtime.po files in a different way.
1706 * data/glr.c (YY_): New macro, from yacc.c.
1707 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
1708 Translate messages intended for users.
1709 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
1710 the wording in the other skeletons. We don't know that the memory
1711 is virtual.
1712 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
1713 Use same method that yacc.c uses.
1714 Don't translate debugging messages.
1715 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
1716 it doesn't work (yet), and requires C++ expertise to fix.
1717 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
1718 Move defn to a more logical place, to be consistent with other
1719 skeletons.
1720 Don't translate debugging messages.
1721 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
1722 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
1723 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
1724 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
1726 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
1727 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
1728 void, not int.
1729 * tests/glr-regression.at (Badly Collapsed GLR States):
1730 Likewise.
1731 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
1732 yylex should return 0 at EOF rather than aborting.
1734 Improve tests for stack overflow in GLR parser.
1735 Problem reported by twlevo@xs4all.nl.
1736 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
1737 All uses removed.
1738 (yyStackOverflow): Just longjmp, but with value 2 so that caller
1739 can handle the problem.
1740 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
1741 (yyparse): New local variable yyresult to record the result.
1742 Use result of setjmp to set it, rather than storing itinto
1743 struct.
1744 (yyDone): Remove label.
1745 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
1746 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
1747 if YYABORT is used).
1748 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
1749 yyparse status; put status > 1 into diagnostic.
1750 Check that status==2 works.
1751 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
1752 Use exit status 3 for failure to open (which shouldn't happen).
1754 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
1756 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
1757 1 on syntax error; just let yyparse do its thing.
1758 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
1759 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
1760 (Exploding the Stack Size with Alloca):
1761 (Exploding the Stack Size with Malloc):
1762 Expect exit status 2, not 1, since the parser is supposed to blow
1763 its stack. Problem reported by twlevo@xs4all.nl.
1765 * data/glr.c (yyparse): Don't assume that the initial calls
1766 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
1767 Print a stack-overflow message and fail instead.
1768 Initialize the line-number information before creating the stack,
1769 so that the stack-overflow message can report line zero safely.
1771 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
1773 Fix problems reported by twlevo@xs4all.nl.
1774 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
1775 (yyuserMerge): Provide a default case if b4_mergers is empty.
1776 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
1777 * tests/glr-regression.at
1778 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
1779 Add casts to pacify C++ compilers.
1780 * tests/glr-regression.at (Improper merging of GLR delayed action
1781 sets): Declare yylex before using it.
1782 * tests/Makefile.am (maintainer-check-g++): Fix a stray
1783 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
1784 test for valgrind; valgrind is independent of g++.
1785 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
1786 for compatibility with POSIX 1003.1-2001 (if running coreutils).
1787 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
1788 Use a destructor, so that we can expand the stack. Change
1789 YYSTYPE to char * so that we can free it. Cast result of malloc.
1791 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
1793 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
1794 a valgrind failure. Problem reported by twlevo@xs4all.nl.
1796 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
1798 * PACKAGING: New file, suggested by Bruno Haible and taken from
1799 similar wording in gettext's PACKAGING file.
1800 * NEWS: Mention PACKAGING.
1801 * Makefile.am (EXTRA_DIST): Add PACKAGING.
1803 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
1805 * NEWS: Document recent i18n improvements.
1806 * bootstrap: Get runtime translations into runtime-po.
1807 Create runtime-po files automatically, if possible.
1808 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
1809 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
1810 does not infringe on the user's name space.
1811 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
1812 * doc/bison.texinfo (Internationalization): Revamp the English
1813 and Texinfo syntax a bit, to try to make it clearer.
1814 (Bison Options, Option Cross Key): Mention --print-localedir.
1815 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
1816 YYENABLE_NLS. Quote a bit more.
1817 * runtime-po/.cvsignore: New file.
1818 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
1819 * runtime-po/Rules-quot: Remove; now created by bootstrap.
1820 * runtime-po/quot.sed: Likewise.
1821 * runtime-po/boldquot.sed: Likewise.
1822 * runtime-po/en@quot.header: Likewise.
1823 * runtime-po/en@boldquot.header: Likewise.
1824 * runtime-po/insert-header.sin: Likewise.
1825 * runtime-po/remove-potcdate.sin: Likewise.
1826 * runtime-po/Makevars: Likewise.
1827 * runtime-po/LINGUAS: Likewise.
1828 * runtime-po/de.po: Likewise; we will rely on the translation project
1829 to maintain this, so "bootstrap" should get it.
1830 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
1831 its value.
1832 * src/main.c (main): Bind the bison-runtime domain, too.
1834 2005-07-12 Bruno Haible <bruno@clisp.org>
1836 * data/yacc.c: Include <libintl.h> when NLS is enabled.
1837 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
1838 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
1839 * runtime-po: New directory.
1840 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
1841 $(DOMAIN).pot-update rule, so that old messages are never dropped.
1842 * runtime-po/Rules-quot: New file, copied from po/.
1843 * runtime-po/quot.sed: Likewise.
1844 * runtime-po/boldquot.sed: Likewise.
1845 * runtime-po/en@quot.header: Likewise.
1846 * runtime-po/en@boldquot.header: Likewise.
1847 * runtime-po/insert-header.sin: Likewise.
1848 * runtime-po/remove-potcdate.sin: Likewise.
1849 * runtime-po/Makevars: New file.
1850 * runtime-po/POTFILES.in: New file.
1851 * runtime-po/LINGUAS: New file.
1852 * runtime-po/bison-runtime.pot: New file.
1853 * runtime-po/de.po: New file.
1854 * m4/bison.m4: New file.
1855 * Makefile.am (SUBDIRS): Add runtime-po.
1856 (aclocaldir, aclocal_DATA): New variables.
1857 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
1858 Define aclocaldir.
1859 * src/getargs.c (usage): Document --print-localedir option.
1860 (PRINT_LOCALEDIR_OPTION): New enum item.
1861 (long_options): Add --print-localedir option.
1862 (getargs): Handle --print-localedir option.
1863 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
1864 (Internationalization): New section.
1866 2005-07-12 Akim Demaille <akim@epita.fr>
1868 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
1869 for consistency with the rest of the code.
1870 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
1871 Add separators.
1873 2005-07-12 Akim Demaille <akim@epita.fr>
1875 * src/parse-gram.y: Use %printer instead of YYPRINT.
1877 2005-07-12 Akim Demaille <akim@epita.fr>
1879 * src/symtab.h, src/symtab.c (symbol_print): New.
1880 * src/symlist.h, src/symlist.c (symbol_list_print): New.
1881 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
1883 2005-07-12 Akim Demaille <akim@epita.fr>
1885 * data/glr.c (b4_syncline): Fix (swap) the definitions of
1886 b4_at_dollar and b4_dollar_dollar.
1888 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
1890 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
1891 and Pennello's paper.
1893 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
1895 * data/yacc.c (yyparse): Undo previous patch. Instead,
1896 set yylsp[0] and yyvsp[0] only if the initial action
1897 sets yylloc and yylval, respectively.
1899 * data/yacc.c (yyparse): In the initial action, set
1900 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
1901 This avoids the use of undefined variables if the initial
1902 action does not set yylloc and/or yylval.
1904 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1906 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
1907 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
1908 Remove from CVS. These files are automatically generated.
1909 * examples/extexi: Clarify that this file is now part of Bison,
1910 not GNU M4, and that it works with any POSIX-compatible Awk.
1911 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
1912 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
1913 so that we also get calc++-parser.yy. Geneate it.
1914 Use $(AWK), not gawk, since any conforming Awk will do.
1915 Put comment before action, since older 'make' can't handle comment
1916 in action.
1917 $(BUILT_SOURCES): List all built sources, not just some of them.
1918 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
1919 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
1920 $($(calc_sources_generated)): Remove unnecessary test for existence
1921 of target. (This had a shell syntax error anyway; a stray "x".)
1922 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
1923 calc++-parser.yy.
1924 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
1926 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
1927 implied by the other modules.
1929 2005-07-06 Akim Demaille <akim@epita.fr>
1931 Bind examples/calc++ to the package.
1932 * examples/calc++/Makefile: Remove, replaced by...
1933 * examples/calc++/Makefile.am: ... this new file.
1934 * examples/calc++/test: Remove input.
1935 * examples/calc++/compile: Remove.
1936 * examples/Makefile.am: New.
1937 * configure.ac, Makefile.am: Adjust.
1938 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
1940 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
1942 * data/glr.c (yyFail): Drastically simplify; since the format argument
1943 never had any % directives, we can simply pass it to yyerror.
1944 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
1945 be modified later, as that is the usual style in glr.c.
1946 Problems reported by Paul Hilfinger.
1948 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
1949 and size overflow errors.
1950 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
1951 in case the user prolog sets feature-test macros like _GNU_SOURCE.
1952 (YYSIZEMAX): New macro.
1953 (yystpcpy): New function, taken from yacc.c.
1954 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
1955 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
1956 so that we don't have to maintain their signatures.
1957 (yyFail): Check for buffer overflow, by using vsnprintf rather
1958 than vsprintf. Allocate a bigger buffer if possible.
1959 Report an error if buffer allocation fails.
1960 (yyStackOverflow): New function.
1961 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
1962 the initialization was successful. It might fail if storage was
1963 exhausted.
1964 (yyexpandGLRStack): Add more checks for storage allocation failure.
1965 Use yyStackOverflow to report failures.
1966 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
1967 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
1968 Don't assume stack number fits in int.
1969 (yysplitStack): Check for storage allocation failure.
1970 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
1971 can print diagnostics on storage allocation failure. All callers
1972 changed.
1973 (yyresolveValue): Use yybool for boolean.
1974 (yyreportSyntaxError): Check for size-calculation overflow.
1975 This code is taken from yacc.c.
1976 (yyparse): Check for storage allocation errors when allocating
1977 the initial stack.
1979 2005-07-05 Akim Demaille <akim@epita.fr>
1981 Extract calc++ from the documentation.
1982 * doc/bison.texinfo (Calc++): Add the extraction marks.
1983 * examples/extexi: New, from the aborted GNU Programming 2E.
1984 Separate the different paragraph of a file with empty lines.
1985 * examples/Makefile: Use it to extract the whole calc++ example.
1987 2005-06-24 Akim Demaille <akim@epita.fr>
1989 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
1990 class typedefs.
1992 2005-06-22 Akim Demaille <akim@epita.fr>
1994 * doc/bison.texinfo (C++ Language Interface): First stab.
1995 (C++ Parsers): Remove.
1997 2005-06-22 Akim Demaille <akim@epita.fr>
1999 * data/lalr1.cc (yylex_): Honor %lex-param.
2001 2005-06-22 Akim Demaille <akim@epita.fr>
2003 Start a set of simple examples.
2004 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
2005 * examples/calc++/calc++-driver.hh,
2006 * examples/calc++/calc++-parser.yy,
2007 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
2008 * examples/calc++/compile, examples/calc++/test: New.
2010 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
2012 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2013 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2014 which stems from the 2005-05-27 patch.
2016 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2018 * data/glr.c: Modify treatment of unused parameters to permit use
2019 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2021 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2023 Fix infringement on user name space reported by Janos Zoltan Szabo.
2024 * data/yacc.c (yyparse): strlen -> yystrlen.
2026 2005-05-30 Akim Demaille <akim@epita.fr>
2028 * data/lalr1.cc (_): New.
2029 Translate the various messages.
2031 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2033 Fix infringement on user name space reported by Bruno Haible.
2034 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2035 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2036 the user's name space.
2037 (alloca): Include <stdlib.h> to get it, if it's not built in.
2038 (YYMALLOC, YYFREE): Define only if needed.
2039 (malloc, free): Declare, but only if needed, as this infringes on
2040 the user name space.
2042 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2044 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
2045 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
2046 with %d format.
2047 * lib/ebitset.c (min, max): Undef before defining.
2048 * lib/vbitset.c (min, max): Likewise.
2049 * lib/subpipe.c (create_subpipe): Save local variables in case
2050 vfork clobbers them.
2052 2005-05-24 Bruno Haible <bruno@clisp.org>
2054 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
2055 error message syntax used by gcc-4.0.
2057 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
2059 * README: Mention m4 1.4.3. Remove obsolete advice about
2060 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
2062 * bootstrap: Remove workaround for problem I encountered with
2063 gettext 0.14.1; it seems to be fixed now.
2065 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
2067 * NEWS: Version 2.0a.
2069 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2070 the previous change.
2072 Various maintainer cleanups.
2073 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2074 conftest*, for benefit of CVS commands run at the same time as
2075 "configure". Add build-aux, since "bootstrap" now creates it and
2076 its subfiles.
2077 * Makefile.cfg (move_if_change): Remove.
2078 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2079 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
2080 (po_repo, do-po-update, po-update, wget_files, get-targets):
2081 (config.guess-url_prefix, config.sub-url_prefix):
2082 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
2083 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
2084 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
2085 Remove.
2086 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
2087 this is now the recommended name.
2088 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2089 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2090 ylwrap. These files now go into build-aux.
2091 * config/move-if-change: Remove.
2092 * config/prev-version.txt: Bump from 1.75 to 2.0.
2094 * bootstrap: Add stdio-safer, unistd-safer modules.
2095 Remove m4/glibc2.m4 (introduced by latest gnulib, but
2096 we don't need it).
2097 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
2098 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2099 * lib/subpipe.c: Include "unistd-safer.h".
2100 (create_subpipe): Make sure all the newly-created
2101 file descriptors are > 2, so that diagnostics don't
2102 get sent down them (which might cause Bison to hang, in theory).
2103 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2104 * src/files.c (xfopen): Use fopen_safer, not fopen.
2106 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2107 yesterday's yacc.c fix.
2109 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
2111 * data/glr.c, data/lalr1.cc: Update copyright date.
2113 Fix a destructor bug reported by Wolfgang Spraul in
2114 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
2115 * data/yacc.c (yyabortlab): Don't call destructor, and
2116 don't set yychar to EMPTY.
2117 (yyoverflowlab): Don't call destructor.
2118 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2119 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2120 since we no longer output the message "discarding lookahead token
2121 end of input ()".
2123 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2125 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2126 fix a small glitch in debugging output.
2127 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2128 after YY_SYMBOL_PRINT where needed.
2130 (struct yyGLRState): Add some comments.
2131 (struct yySemanticOption): Add some comments.
2132 (union yyGLRStackItem): Add comment.
2134 (yymergeOptionSets): Correct this to properly perform the union,
2135 avoiding infinite reported by Michael Rosien.
2136 Update comment.
2138 * tests/glr-regression.at: Add test for GLR merging error reported
2139 by M. Rosien.
2141 2005-05-13 Paul Eggert <eggert@cs.ucla.edu>

2179 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
2181 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
2182 Problem reported by Ralf Menzel.
2184 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2186 * tests/actions.at: Test that stack overflow invokes destructors.
2187 From Marcus Holland-Moritz.
2188 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2189 from here....
2190 (yyreturn): to here. That way, destructors are called properly
2191 even if the stack overflows, or the user calls YYACCEPT or
2192 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2193 (yyoverflowlab): Destroy the lookahead.
2195 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2197 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2199 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2201 * NEWS: Bison-generated C parsers no longer quote literal strings
2202 associated with tokens.
2203 * src/output.c (prepare_symbols): Don't escape strings,
2204 since users don't want to see C escapes.
2205 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2206 in diagnostics.
2207 * tests/input.at (Torturing the Scanner): Likewise.
2208 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2210 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2212 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2213 the data size is known to be too small and we can't increase it.
2214 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2216 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2218 * src/parse-gram.y: Include quotearg.h.
2219 (string_as_id): Quote $1 before using it as a key, since the
2220 lexer no longer quotes it for us.
2221 (string_content): Don't strip quotes, since lexer no longer
2222 quotes it for us.
2223 * src/scan-gram.l: Include quotearg.h.
2224 ("\""): Omit quote.
2225 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2226 a key, since the rest of the lexer doesn't quote it.
2227 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2228 * tests/regression.at (Token definitions): Check for backslashes
2229 in token strings.
2231 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2232 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2233 (yyparse): Revamp code to generate long syntax error message, to
2234 make it easier to translate, and to avoid problems with arithmetic
2235 overflow. Change "virtual memory" to "memory" in diagnostic, since
2236 we don't know whether the memory is virtual.
2238 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2240 * NEWS: Bison-generated C parsers now use the _ macro to
2241 translate strings.
2242 * data/yacc.c (_) [!defined _]: New macro.
2243 All English strings wrapped inside this macro.
2244 * doc/bison.texinfo (Bison Parser): Document _.
2245 * po/POTFILES.in: Include src/parse-gram.c, since it now
2246 includes translateable strings that parse-gram.y doesn't.
2248 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2250 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2251 reverting the 2004-10-11 change to this function.
2252 (symbol_check_alias_consistency): Don't call symbol_type_set
2253 if the type name is already correct.
2254 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2256 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2258 * tests/regression.at (Token definitions): Don't use a token named
2259 c, as that generates a "#define c ..." that runs afoul of buggy
2260 stdlib.h that uses the identifier c as a member of struct
2261 drand48_data. Problem reported by Horst Wente.
2263 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2265 * bootstrap: Change translation URL from
2266 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2267 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2268 redirection glitches. Problem reported by twlevo@xs4all.nl.
2270 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2272 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2273 after operands; POSIX says this isn't portable for the c99 command.
2275 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2277 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2278 immediately if a data overrun has occurred; this may help us track
2279 down what may be a spurious failure on MacOS.
2281 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2283 Respond to problems reported by twlevo@xs4all.nl.
2285 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
2287 * src/vcg.h: Comment fix.
2288 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2289 (G_CMAX): Change to -1 instead of INT_MAX.
2291 * data/yacc.c (yyparse): Omit spaces before #line.
2293 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2295 * src/tables.c (state_number_to_vector_number): Put it inside an
2296 "#if 0", since it's not currently used. Problem reported by
2297 Roland McGrath.
2299 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2301 * src/output.c (escaped_output): Renamed from
2302 escaped_file_name_output, since we now use it for symbol tags as
2303 well. All uses changed.
2304 (symbol_destructors_output, symbol_printers_output):
2305 Escape symbol tags too.
2306 Problem reported by Matyas Forstner in
2307 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2309 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2310 not needed.
2311 * src/output.c (user_actions_output, token_definitions_output,
2312 symbol_destructors_output, symbol_printers_output): Likewise.
2313 * src/reader.c (prologue_augment): Likewise.
2314 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2316 * src/vcg.c (output_edge): Don't quote linestyle arg.
2317 Problem reported by twlevo@xs4all.nl.
2319 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2321 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2322 example, reported by Derek M Jones. Also, make the example even
2323 more outrageous, to better illustrate how bad the problem is.
2325 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2327 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2328 putsym. Typo reported by Sebastian Piping.
2330 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2332 * doc/bison.texinfo (Language and Grammar): some -> same
2333 (Epilogue): int he -> in the
2334 Typos reported by Sebastian Piping via Justin Pence.
2336 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2338 * tests/glr-regression.at (Improper handling of embedded actions
2339 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2340 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2341 with dollar signs in test names.
2342 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2343 for a similar reason.
2345 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2347 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2348 wants to redefine G_VIEW.
2350 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
2352 * src/vcg.c (get_view_str): Remove case for normal_view.
2353 Problem reported by twlevo@xs4all.nl.
2355 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
2357 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
2358 Problem reported by twlevo@xs4all.nl.
2360 * doc/bison.texinfo: Change @dircategory from "GNU programming
2361 tools" to "Software development". Requested by Richard Stallman
2362 via Karl Berry.
2364 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
2366 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
2367 Problem reported by twlevo@xs4all.nl.
2369 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2371 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2372 keyword; it's not needed with modern compilers, and it doesn't
2373 affect correctness with older compilers. Suggested by
2374 twlevo@xs4all.nl.
2376 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2378 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2379 gcc -Wswitch-default.
2380 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2381 * data/yacc.c (yyparse): Likewise.
2383 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2385 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2386 already. Let config.h define any nonstandard values.
2388 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2390 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2391 for the benefit of slower hosts. Problem reported by
2392 Nelson H. F. Beebe.
2394 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2396 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2397 being defined and not used.
2398 * data/lalr1.cc (yyparse): Likewise.
2399 Use "if (false)" rather than "if (0)".
2401 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2403 * TODO: Mention that we should allow NUL bytes in tokens.
2405 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
2407 * src/scan-skel.l (<<EOF>>): Don't close standard output.
2408 Problem reported by Hans Aberg.
2410 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
2412 * src/getargs.c (version): Happy new year; update overall
2413 program copyright date from 2004 to 2005.
2415 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2416 Problem reported by Hans Aberg.
2417 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2418 (Output file names.): Add a test for the case when standard output
2419 is closed.
2421 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2423 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2424 to fix an oversight in the Bison 2.0 manual.
2426 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2428 * NEWS: Version 2.0. Reformat the existing news items since
2429 1.875, so that related items are grouped together.
2430 * configure.ac (AC_INIT): Bump version to 2.0.
2431 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2433 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2434 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2435 otherwise, we're not testing alloca. Unfortunately there's no
2436 simple way to consult HAVE_ALLOCA here.
2438 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2439 for yymsg, too.
2441 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2442 hand. This avoids a warning about comparing int to size_t when
2443 GCC warnings are enabled.
2445 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2447 * NEWS: Bison-generated parsers no longer default to using the
2448 alloca function (when available) to extend the parser stack, due
2449 to widespread problems in unchecked stack-overflow detection.
2450 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2451 responsibility to set it to a positive value. This lets the user
2452 specify a value that is not a preprocessor constant.
2453 * data/yacc.c (YYMAXDEPTH): Likewise.
2454 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2455 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2456 to be a compile-time constant. However, explain the constraints on it.
2457 Also, explain the constraints on YYINITDEPTH.
2458 (Table of Symbols): Explain that alloca is no longer the default.
2459 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2460 to 1.
2462 * doc/bison.texinfo (Location Default Action): Mention that n must
2463 be zero when k is zero. Suggested by Frank Heckenbach.
2465 2004-12-22 Akim Demaille <akim@epita.fr>
2467 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
2468 (parser::state_type, parser::semantic_type, parser::location_type):
2469 Private, not public.
2470 (parser::parse): Return ints, not bool.
2471 Returning a bool introduces a problem: 0 corresponds to false, and
2472 it seems weird to return false on success. Returning true changes
2473 the conventions for yyparse.
2474 Alternatively we could return void and send an exception.
2475 There is no clear consensus (yet?).
2476 (state_stack, semantic_stack, location_stack): Rename as...
2477 (state_stack_type, semantic_stack_type, location_stack_type): these.
2478 Private, not public.
2479 * tests/c++.at: New.
2480 * tests/testsuite.at, tests/Makefile.am: Adjust.
2482 2004-12-21 Akim Demaille <akim@epita.fr>
2484 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
2486 2004-12-21 Akim Demaille <akim@epita.fr>
2488 Don't impose std::string for filenames.
2490 * data/lalr1.cc (b4_filename_type): New.
2491 (position::filename): Use it.
2492 (parser.hh): Move the inclusion of stack.hh and location.hh below
2493 the user code, so that needed headers for the filename type can be
2494 included first.
2495 Forward declare them before the user code.
2496 * tests/Makefile.am (check-local, installcheck-local): Pass
2497 TESTSUITEFLAGS to the TESTSUITE.
2499 2004-12-20 Akim Demaille <akim@epita.fr>
2501 Use more STL like names: my_class instead of MyClass.
2503 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
2504 (SemanticStack, SemanticType, StateStack, StateType)
2505 (TokenNumberType, Stack, Slice, Traits, Parser::location)
2506 (Parser::value): Rename as...
2507 (location_stack, location_type, rhs_number_type, semantic_stack)
2508 (semantic_type, state_stack, state_type, token_number_type, stack)
2509 (slice, traits, parser::yylloc, parser::yylval): these.
2511 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
2513 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
2515 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
2516 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
2518 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
2520 Remove uses of 'short int' and 'unsigned short int'. This raises
2521 some arbitrary limits. It uses more memory but nowadays that's
2522 not much of an issue.
2524 This change does not affect the generated parsers; that's a different
2525 task, as some users will want to conserve memory there.
2527 Ideally we should use size_t to represent all object counts, and
2528 something like ptrdiff_t to represent signed differences of object
2529 counts; but that will require more code-cleanup than I have the
2530 time to do right now.
2532 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
2533 Use size_t, not int or short int, to count objects.
2534 * src/closure.c (nritemset, closure): Likewise.
2535 * src/closure.h (nritemset, closure): Likewise.
2536 * src/nullable.c (nullable_compute): Likewise.
2537 * src/print.c (print_core): Likewise.
2538 * src/print_graph.c (print_core): Likewise.
2539 * src/state.c (state_compare, state_hash): Likewise.
2540 * src/state.h (struct state): Likewise.
2541 * src/tables.c (default_goto, goto_actions): Likewise.
2543 * src/gram.h (rule_number, rule): Use int, not short int.
2544 * src/output.c (prepare_rules): Likewise.
2545 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
2546 errs, reductions): Likewise.
2547 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
2548 Likewise.
2549 * src/tables.c (vector_number, tally, action_number,
2550 ACTION_NUMBER_MINIMUM): Likewise.
2551 * src/output.c (muscle_insert_short_int_table): Remove.
2553 2004-12-17 Akim Demaille <akim@epita.fr>
2555 * data/lalr1.cc: Extensive Doxygenation.
2556 (error_): Rename as...
2557 (error): this, since it is visible to the user.
2558 Adjust callers.
2559 (Parser::message): Now an automatic variable from...
2560 (Parser::yyreport_syntax_error_): here.
2561 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
2562 Parser::error.
2563 * tests/input.at: Escape $.
2565 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
2567 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
2568 Parenthesize rhs to avoid obscure problems with mistakes like
2569 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
2570 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2571 b4_rhs_location): Likewise.
2572 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2573 b4_rhs_location): Likewise.
2575 2004-12-16 Akim Demaille <akim@epita.fr>
2577 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
2578 yacc.c: be sure to stay within yycheck_.
2579 * tests/actions.at: Re-enable C++ tests.
2581 2004-12-16 Akim Demaille <akim@epita.fr>
2583 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
2584 real.
2586 2004-12-16 Akim Demaille <akim@epita.fr>
2588 Use #define to handle the %name-prefix.
2590 * data/glr.c, data/yacc.c: Comment changes.
2591 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
2592 so that one can refer to yylex in the parser file, and have it
2593 renamed, as is the case with other skeletons.
2595 2004-12-16 Akim Demaille <akim@epita.fr>
2597 Move lalr1.cc internals into yy*.
2599 * data/lalr1.cc (semantic_stack_, location_stack_, state_stack_)
2600 (semantic_stack_, location_stack_, pact_, pact_ninf_, defact_)
2601 (pgoto_, defgoto_, table_, table_ninf_, check_, stos_, r1_, r2_)
2602 (name_, rhs_, prhs_, rline_, token_number_, eof_, last_, nnts_)
2603 (empty_, final_, terror_, errcode_, ntokens_)
2604 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
2605 (looka_, ilooka_, error_range_, nerrs_):
2606 Rename as...
2607 (yysemantic_stack_, yylocation_stack_, yystate_stack_)
2608 (yysemantic_stack_, yylocation_stack_, yypact_, yypact_ninf_)
2609 (yydefact_, yypgoto_, yydefgoto_, yytable_, yytable_ninf_)
2610 (yycheck_, yystos_, yyr1_, yyr2_, yyname_, yyrhs_, yyprhs_)
2611 (yyrline_, yytoken_number_, yyeof_, yylast_, yynnts_, yyempty_)
2612 (yyfinal_, yyterror_, yyerrcode_, yyntokens_)
2613 (yyuser_token_number_max_, yyundef_token_, yyn_, yylen_, yystate_)
2614 (yynerrs_, yylooka_, yyilooka_, yyerror_range_, yynerrs_):
2615 these.
2617 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
2619 Fix some problems reported by twlevo at xs4all.
2620 * src/symtab.c (symbol_new): Report an error if the input grammar
2621 contains too many symbols. This is better than calling abort() later.
2622 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
2623 (struct node, struct graph):
2624 Rename member expand to stretch. All uses changed.
2625 (struct graph): Remove member layoutalgorithm. All uses removed.
2626 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
2627 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
2628 All uses changed.
2629 (N_STRETCH): Rename from N_EXPAND. All uses changed.
2631 2004-12-15 Akim Demaille <akim@epita.fr>
2633 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
2634 Add more Doxygen comments.
2635 (symprint_, stack_print_, reduce_print_, destruct_, pop)
2636 (report_syntax_error_, translate_): Rename as...
2637 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
2638 (yypop_, yyreport_syntax_error_, yytranslate_): this.
2640 2004-12-15 Akim Demaille <akim@epita.fr>
2642 * data/lalr1.cc (lex_): Rename as...
2643 (yylex_): this.
2644 Move the trace here.
2645 Take the %name-prefix into account.
2646 Reported by Alexandre Duret-Lutz.
2648 2004-12-15 Akim Demaille <akim@epita.fr>
2650 Simplify the C++ parser constructor.
2652 * data/lalr1.cc (debug_): Rename as...
2653 (yydebug_): so that the parser's internals are always in the yy*
2654 pseudo namespace.
2655 Adjust uses.
2656 (b4_parse_param_decl): Remove the leading comma as it is now only
2657 called as unique argument list.
2658 (Parser::Parser): Remove the constructor accepting a location and
2659 an initial debugging level.
2660 Remove from the other ctor the argument for the debugging level.
2661 (debug_level_type, debug_level, set_debug_level): New.
2663 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
2664 constructor calls.
2666 2004-12-15 Akim Demaille <akim@epita.fr>
2668 Remove b4_root related material: failure experiment
2669 (which goal was to allow to derive from a class).
2671 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
2672 definitions and uses.
2674 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
2676 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
2677 not 2, since it's not portable to subtract 1 from the start of an
2678 array. The new item 0 is never set or used. All uses changed.
2680 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
2681 the default definition of YYLLOC_DEFAULT. Problem reported
2682 by Frank Heckenbach.
2684 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
2686 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
2687 the normal case and one for the error case. Just use the
2688 first one uniformly. Problem reported by Frank Heckenbach.
2689 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
2690 use exactly the same macro in both places.
2691 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
2692 so that the normal-case YYRHSLOC works for the error case too.
2693 All uses changed.
2694 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
2695 (YYLLOC_DEFAULT): Use the same macro as glr.c.
2696 * doc/bison.texinfo (Location Default Action): Don't claim that
2697 we have an array of locations. Use the same macro for both glr
2698 and lalr parsers. Mention YYRHSLOC. Mention what happens when
2699 the index is 0.
2701 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
2703 * HACKING: Update email addresses to send announcements to.
2705 * configure.ac (AC_INIT): Bump version to 1.875f.
2707 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
2709 * NEWS: Version 1.875e.
2710 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
2712 * src/scan-skel.l: Include "complain.h", for "fatal".
2714 * src/relation.h (relation_print, relation_digraph):
2715 Relation sizes are of type relation_node, not size_t (this is
2716 merely a doc fix, since the two types are equivalent).
2717 (relation_transpose): Relation sizes are of type relation_node,
2718 not int.
2719 * src/relation.c: Likewise.
2720 (top, infinity): Now of type relation_node, not int.
2721 (traverse, relation_transpose): Use relation_node, not int.
2723 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
2724 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
2725 (yyparse): Remove unused local introduced in 2004-10-25 patch.
2727 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
2728 specifying whether the test should be skipped. Use it tp
2729 specify that the [%defines %skeleton "lalr1.cc"] tests currently
2730 fail on some hosts, and should be skipped.
2732 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
2734 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
2735 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
2736 unless otherwise specified below.
2738 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
2739 to allocate kernel_base, kernel_items, kernel_size, since
2740 they needn't be initialized to 0.
2741 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
2742 * src/closure.c (new_closure): Likewise, for itemset.
2743 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
2744 * src/lalr.c (set_goto_map): Likewise, for temp_map.
2745 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
2746 (build_relations): Likewise for edge, states1, includes.
2747 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
2748 * src/reader.c (packgram): Likewise, for ritem, rules.
2749 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.

2753 token_translations.
2754 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
2755 (token_actions): Likewise for yydefact, actrow, conflrow,
2756 conflict_list.
2757 (save_column): Likewise for froms[symno], tos[symno].
2758 (goto_actions): Likewise for state_count.
2759 (pack_table): Likewise for base, pos, check.
2760 (tables_generate): Likewise for width.
2762 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
2763 for initial core. Just have a separate core, so we needn't worry
2764 about whether kernel_size and kernel_base are initialized.
2766 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
2767 kernel_size, kernel_items): Remove unnecessary initialization.
2768 * src/conflicts.c (conflicts): Likewise.
2769 * src/derives.c (derives): Likewise.
2770 * src/muscle_tablc (muscle_insert): Likewise.
2771 * src/relation.c (relation_digraph): Likewise.
2772 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
2773 conflrow, conflict_table, conflict_list, table, check):
2774 Likewise.
2776 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
2777 This is because all callers pass unsigned int.
2778 * src/closure.h (new_closure): Likewise.
2780 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
2781 (build_relations): Initialize includes[i] in all cases.
2782 * src/reader.c (packgram): Always initialize rules[ruleno].prec
2783 and rules[ruleno].precsym. Initialize members in order.
2784 * src/relation.c (relation_transpose): Always initialize new_R[i]
2785 and end_R[i].
2786 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
2788 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
2789 conflict_list[0] was always 0, but now it isn't initialized.
2791 * src/table.c (table_grow): When conflict_table grew, the grown
2792 area wasn't cleared. Fix this.
2794 * lib/.cvsignore: Add strdup.c, strdup.h.
2795 * m4/.cvsignore: Add strdup.m4.
2797 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
2799 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
2800 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
2801 GOTO_NUMBER_MAXIMUM, since we occasionally compute
2802 ngotos + 1 without checking for overflow.
2803 (build_relations): Use END_NODE, not -1, to denote end of edges.
2804 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
2805 build_relations): Use goto_number, not int, for goto numbers.
2806 * src/tables.c (save_column, default_goto): Likewise.
2808 2004-11-23 Akim Demaille <akim@epita.fr>
2810 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
2811 of #defining from yystype.
2812 Don't typedef yystype, C++ does not need it.
2813 This lets it possible to forward declare it as union.
2815 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
2817 * bootstrap (gnulib_modules): Add extensions.
2818 Problem reported by Jim Meyering.
2820 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
2822 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
2823 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
2824 src/system.h, src/tables.c: XFREE -> free, to accommodate
2825 recent change to gnulib xalloc.h.
2826 Problem reported by Jim Meyering.
2828 2004-11-17 Akim Demaille <akim@epita.fr>
2830 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
2832 2004-10-28 Akim Demaille <akim@epita.fr>,
2833 Alexandre Duret-Lutz <adl@gnu.org>
2835 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
2836 changes.
2837 (YYCDEBUG): Adjust.
2838 Use it instead of cdebug_.
2839 (Parser::debug_stream, Parser::set_debug_stream): New.
2840 (Parser::symprint_): Define cdebug_ for temporary backward
2841 compatibility.
2842 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
2843 debug_stream ().
2845 2004-11-17 Akim Demaille <akim@epita.fr>
2847 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
2848 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
2849 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
2850 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
2852 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
2854 * data/glr.c (yyloc_default): Remove; not used.
2855 Problem reported by Frank Heckenbach.
2857 2004-10-25 Akim Demaille <akim@epita.fr>
2859 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
2860 Introduce another definition to address simple location arrays.
2861 (yyGLRStack): New member: yyerror_range.
2862 (yyrecoverSyntaxError, yyparse): Update it.
2863 (yyrecoverSyntaxError): Use it when shifting the error token to
2864 have an accurate range, equivalent to the one computed by both
2865 yacc.c and lalr1.cc.
2866 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
2867 that column numbers start at column 0, as per GNU Coding
2868 Standards, the others tests, and the doc.
2869 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
2870 Adjust to the above change (first column is 0).
2871 And adjust the location of the "<error>", now covering the whole
2872 line.
2874 2004-10-22 Akim Demaille <akim@epita.fr>
2875 and Paul Eggert <eggert@cs.ucla.edu>
2877 Remove some arbitrary limits on goto numbers and relations.
2878 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
2879 initial values, since they're never used.
2880 (set_goto_map): ngotos is now unsigned, so test for overflow
2881 by seeing whether it wraps around to zero.
2882 * src/lalr.h (goto_number): Now size_t, not short int.
2883 (GOTO_NUMBER_MAXIMUM): Remove.
2884 * src/relation.c (relation_print, traverse, relation_transpose):
2885 Check for END_NODE rather than looking at sign.
2886 * src/relation.h (END_NODE): New macro.
2887 (relation_node): Now size_t, not short int.
2889 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
2891 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
2892 keyword, not an identifier. Problem reported by Baron Schwartz in
2893 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
2895 2004-10-11 Akim Demaille <akim@epita.fr>
2897 * src/symtab.c (symbol_check_alias_consistency): Also check
2898 type names, destructors, and printers.
2899 Reported by Alexandre Duret-Lutz.
2900 Recode the handling of associativity and precedence in terms
2901 of symbol_precedence_set.
2902 Accept no redeclaration at all, not even equal to the previous
2903 value.
2904 (redeclaration): New.
2905 Use it to factor redeclaration complaints.
2906 (symbol_make_alias): Don't set the type of the alias, let
2907 symbol_check_alias_consistency do it as for other features.
2908 * src/symtab.h (symbol): Add new member prec_location, and
2909 type_location.
2910 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
2911 * tests/input.at (Incompatible Aliases): New.
2913 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
2915 .cvsignore fixes to accommodate gnulib changes,
2916 and the practice of naming build directories "_build".
2917 * .cvsignore: Add "_*". Sort.
2918 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
2919 * m4/.cvsignore: Add "*_gl.m4".
2921 2004-10-06 Akim Demaille <akim@epita.fr>
2923 * src/parse-gram.y (add_param): Fix the truncation of trailing
2924 spaces.
2926 2004-10-05 Akim Demaille <akim@epita.fr>
2928 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
2929 whether the reducion was empty or not. This leaves room to
2930 improve the use of YYLLOC_DEFAULT in such a case.
2931 lalr1.cc is still experimental, so changing this is acceptable.
2932 And finally, there are probably not many users who changed the
2933 handling of locations in GLR, so changing is admissible too.
2935 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
2936 empty reduction, set @$ to an empty location ending the previously
2937 stacked symbol.
2938 Adjust uses to make sure the code is triggered on empty
2939 reductions.
2940 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
2941 expected output: empty reductions have empty locations.
2943 2004-09-29 Akim Demaille <akim@epita.fr>
2945 * data/lalr1.cc: Move towards a more standard C++ coding style
2946 for templates: Class < T > -> Class<T>.
2948 2004-09-29 Akim Demaille <akim@epita.fr>
2950 * data/lalr1.cc: Reinstall the former ctor, for sake of
2951 compatibility, but warn it will be removed.
2952 Move towards a more standard C++ coding style (i.e., type *var ->
2953 type* var).
2955 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
2957 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
2958 since it's less likely to work if NULs are involved in the future.
2960 2004-09-27 Akim Demaille <akim@epita.fr>
2962 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
2964 2004-09-27 Akim Demaille <akim@epita.fr>
2966 * data/lalr1.cc (b4_parse_param_decl_1): New.
2967 (b4_parse_param_decl): Use it to have different names between attribute
2968 and argument names.
2969 (b4_cc_constructor_call): Likewise.
2971 2004-09-24 Akim Demaille <akim@epita.fr>
2973 * src/parse-gram.y (add_param): Strip the leading and trailing
2974 blanks from a formal argument declaration.
2975 (YY_LOCATION_PRINT): New.
2977 2004-09-24 Akim Demaille <akim@epita.fr>
2979 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
2980 after the location.
2982 2004-09-24 Akim Demaille <akim@epita.fr>
2984 * doc/bison.texinfo (Table of Symbols): Sort.
2986 2004-09-21 Akim Demaille <akim@epita.fr>
2988 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
2989 the useless parentheses.
2990 Suggested by Paul Eggert.
2992 2004-09-20 Akim Demaille <akim@epita.fr>
2994 Let the initial-action act on the look-ahead, and use it for the
2995 "initial push" (corresponding to an hypothetical beginning-of-file).
2996 And let lalr1.cc honor %initial-action.
2998 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
2999 example.
3000 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3001 (Parser::Parser): Remove the ctor that used to initialize it.
3002 (Parser::parse): Like in the other skeletons, issue the "starting
3003 parse" message before any action.
3004 Honor %initial-action.
3005 Initialize the stacks with the lookahead.
3006 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3007 look-ahead.
3008 Push them in the stacks.
3009 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3011 2004-09-20 Akim Demaille <akim@epita.fr>
3013 * doc/bison.texinfo (Initial Action Decl): New.
3015 2004-09-20 Akim Demaille <akim@epita.fr>
3017 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3018 clearer criterion to define it.
3019 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3020 When reducing on an empty RHS, use the latest stacked location as
3021 location.
3022 yylloc is not always available.
3023 * data/glr.c: Likewise.
3024 Also, honor initial-actions.
3026 2004-09-20 Akim Demaille <akim@epita.fr>
3028 * data/yacc.c (YY_LOCATION_PRINT): New.
3029 Define when we know YYLTYPE's structure, i.e., when the default
3030 YYLLOC_DEFAULT is used.
3031 * data/c.m4 (b4_yysymprint_generate): Use it.
3032 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3033 value of the result.
3034 (error_start_): Replace with...
3035 (error_range_): this location array.
3036 This allows to replace code relying on the implementation of
3037 locations by portable code.
3038 * data/yacc.c (yylerrsp): Replace with...
3039 (yyerror_range): this.
3040 Every time a token is popped, update yyerror_range[0], to have an
3041 accurate location for the error token.
3042 * data/glr.c (YY_LOCATION_PRINT): New.
3043 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3044 deference a pointer.
3045 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3046 report the location in %printers.
3048 * src/scan-skel.l: Instead of abort, report error messages to ease
3049 understanding skeleton scanning failures.
3051 2004-09-16 Akim Demaille <akim@epita.fr>
3053 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3054 (iterator, const_iterator): these, to be more in the C++ spirit.
3055 Also, return reverse iterators so that when displaying the stack
3056 we display its bottom first.
3057 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3058 from yacc.c.
3059 We should probably use vector here though.
3061 2004-09-16 Akim Demaille <akim@epita.fr>
3063 Have more complete shift traces.
3065 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3066 to report Shifts instead of ad hoc YYDPRINTF invocations,
3067 including for the error token.
3068 * data/lalr1.cc (symprint_): Output the location.
3069 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3070 output the location within the %printer.
3071 Activate GLR tests, at least to make sure they compile properly.
3072 They still don't pass though.
3073 * tests/calc.at: Adjust expect verbose output, since now "Entering
3074 state..." is on a different line than the "Shifting" message.
3076 2004-09-08 Akim Demaille <akim@epita.fr>
3078 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3079 Bison directive from the Bison file to the invocation of this
3080 macro, so that these directives are passed to
3081 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3082 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3083 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3084 the extra Bison directives instead of the whole series.
3085 Change the grammar so that there are recoverable errors, and
3086 unrecoverable errors. Now we can have the parser give up before
3087 consuming the whole input. As a result we now can observe that
3088 the lookahead is freed when needed.
3089 Change the parser source to parse argv[1] instead of a hard coded
3090 string.
3091 Simplify yylex, and give a value and location to EOF.
3092 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3093 passed directives already coded in the file.
3094 Add some tests to check the location of "error".
3095 For some tests, the C++ parser is correct, and not yacc.c.
3096 For other tests, they provide different, but unsatisfying, values,
3097 so keep the C++ value so that at least one parser is "correct"
3098 according to the test suite.
3099 (Actions after errors): Remove, this is subsumed by the
3100 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3102 2004-09-06 Akim Demaille <akim@epita.fr>
3104 * data/lalr1.cc: Adjust the indentation of the labels.
3105 (Parser::pop): New.
3106 Use it.
3108 2004-09-06 Akim Demaille <akim@epita.fr>
3110 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3111 argument, an informative message.
3112 Call YY_SYMBOL_PRINT.
3113 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3114 * data/lalr1.cc (destruct_): Likewise.
3115 In addition, no longer depend on b4_yysymprint_generate and
3116 b4_yydestruct_generate to generate these functions, do it "by
3117 hand".
3119 2004-09-03 Akim Demaille <akim@epita.fr>
3121 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3122 invoked, yydestruct the lookahead.
3123 * tests/calc.at (Calculator $1): Update the expected lengths of
3124 traces: there is an added line for the discarded lookahead.
3125 * doc/bison.texinfo (Destructor Decl): Some rewording.
3126 Define "discarded" symbols.
3128 2004-09-02 Akim Demaille <akim@epita.fr>
3130 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3132 2004-09-02 Akim Demaille <akim@epita.fr>
3134 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3135 (YYDSYMPRINTF): Rename as...
3136 (YY_SYMBOL_PRINT): this.
3137 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3138 two.
3139 Use it instead of direct symprint_ calls.
3140 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3141 one.
3143 2004-09-02 Akim Demaille <akim@epita.fr>
3145 * data/lalr1.cc (b4_yysymprint_generate): New.
3146 (symprint_): New member function, defined when YYDEBUG.
3147 Use it consistently instead of token/nterm debugging output by
3148 hand.
3149 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
3150 %printer calls to use cdebug_ when using lalr1.cc.
3152 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
3154 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
3155 with #ifdef YYDEBUG.
3157 2004-08-26 Akim Demaille <akim@epita.fr>
3159 * doc/bison.texinfo (Implementing Loops): Rename as...
3160 (Implementing Gotos/Loops): this.
3162 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
3164 Adjust to latest gnulib.
3165 * bootstrap (gnulib_modules): Add xalloc-die.
3166 Set LC_ALL=C so that file names sort consistently.
3167 Prefer the gnulib copies of gettext.m4, glibc21.m4,
3168 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
3169 uintmax_t.m4, ulonglong.m4.
3170 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
3171 po.m4 since we are now using _gl.m4 instead.
3173 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
3175 * src/scan-action.l: Remove. Scanning of semantic actions is
3176 handled in scan-gram.l.
3178 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
3180 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
3182 * src/location.h (struct): The file member is a uniqstr.
3183 (equal_boundaries): Use UNIQSTR_EQ for comparison.
3185 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
3187 Fix bug with non-%union parsers that have printers or destructors,
3188 which led to a Bison core dump. Reported by Peter Fales in
3189 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
3191 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
3192 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
3193 not to our own type.
3194 * src/output.c (symbol_destructors_output, symbol_printers_output):
3195 Don't assume %union.
3196 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
3197 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
3198 UNION-FLAG. All callers changed.
3199 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3200 Use type char, not unsigned int, when declaring an array of char;
3201 this lets us remove a cast.
3202 (Printers and Destructors): Add non-%union test cases.
3204 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3206 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3207 GLR writeups. E.g., avoid frenchspacing and the future tense,
3208 change "lookahead" to "look-ahead", and change "wrt" to "with
3209 respect to".
3211 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3213 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
3214 New sections, split off from the GLR Parsers section. Put the new
3215 Simple GLR Parser near the start of the GLR section, for clarity.
3216 Rewrite connective text.
3218 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
3220 * doc/bison.texinfo (Simple GLR Parsers): New section.
3222 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3224 * NEWS, TODO, doc/bison.texinfo:
3225 Use "look-ahead" instead of "lookahead", to be consistent.
3226 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
3227 while we're fixing "look-ahead".
3228 * src/conflicts.c (shift_set): Renamed from shiftset.
3229 (look_ahead_set): Renamed from lookaheadset.
3230 * src/print.c: Likewise.
3231 * src/getargs.c (report_args): Add "look-ahead" as the new canonical

3247 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
3249 * README: Update location of patched M4 distribution.
3251 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
3253 Don't assume the C++ compiler takes the same arguments as the C compiler
3254 (trivial change).
3255 * configure.ac (O0CXXFLAGS): New var.
3256 * tests/atlocal.in (CXXFLAGS): Use it.
3258 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
3260 Fix some "make check" problems with C++ reported by
3261 Albert Chin-A-Young for Tru64 C++ in this thread:
3262 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
3264 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.

3273 * tests/calc.at, tests/actions.at: Workaround for SGI
3274 C++ compiler. (trivial change)
3276 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
3278 Spent a few hours checking out which prerequisite versions the
3279 current sources actually require. I went all the way back to
3280 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3281 a seemingly endless set of combinations of versions more recent
3282 than that. The bottom line is that the current sources require
3283 fairly recent versions of the build tools, and it'll be some work
3284 to change this.
3285 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3286 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3287 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3288 Add comments explaining why those particular versions are
3289 currently needed.
3291 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
3292 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3293 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3295 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
3296 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
3298 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3300 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
3301 0.11.5. Suggested by Bruno Haible.
3302 * bootstrap: Remove gettext version checking.
3304 * doc/bison.texinfo (Decl Summary): Also mention that %union
3305 can depend on prerequisite types. Problem reported by Tim
3306 Van Holder.
3308 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3310 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3311 * README-alpha: Don't tell people not to package this.
3313 * bootstrap: Don't assume $(...) works; use `...` instead.
3314 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3315 gettext better.
3317 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3318 put into the -d output file, and mention what to do if YYSTYPE is
3319 defined as a macro.
3321 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3323 Undo change made earlier today: it caused autopoint to not bring
3324 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3325 autopoint's.
3327 * bootstrap: Check that gettext version matches what's in
3328 configure.ac. Warn users to ignore robots.txt ERROR 404.
3329 * bootstrap: Undo today's earlier change (logged below).
3330 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3332 The gettext version checking is causing more trouble than it's
3333 curing; remove it. Problem reported by Paul Hilfinger.
3335 * bootstrap: Issue a warning that one can expect a message
3336 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3337 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3339 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3341 Ensure that the C++ compiler used for testing actually works on a
3342 simple test program; if not, skip the C++-related tests. Problem
3343 reported by Vin Shelton in:
3344 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
3346 * m4/cxx.m4: New file.
3347 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
3348 * tests/atlocal.in (BISON_CXX_WORKS): Add.
3349 * tests/local.at (AT_COMPILE_CXX): Use it.
3351 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
3353 * data/glr.c (yylloc): Output this macro even if locations are not
3354 being generated, as the GLR parser needs it even in that case.
3355 Problem reported by Troy A. Johnson
3356 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
3358 * configure.ac (AC_INIT): Update to 1.875e.
3360 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
3362 * NEWS: Version 1.875d.
3363 * configure.ac (AC_INIT): Likewise.
3364 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
3366 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
3367 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3368 lalr1.cc runs afoul of the first, and the last two are no longer
3369 supported by GCC 3.4.0.
3370 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3371 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
3373 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
3375 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
3376 unsigned int, for compatibility with latest gnulib hash module.
3377 * src/state.c (state_hash, state_hasher): Likewise.
3378 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
3379 * src/uniqstr.c (hash_uniqstr): Likewise.
3381 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3383 * NEWS: Unescaped newlines are no longer allowed in char & strings.
3385 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
3386 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
3387 character and string literals.
3388 (unexpected_end): New function.
3389 (unexpected_eof): Use it.
3390 (unexpected_newline): New function.
3391 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
3392 actions.
3394 * NEWS: Document %expect-rr.
3396 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
3397 Fix typo by replacing $1 with $option.
3398 Remove more 'intl'-related files.
3399 Don't DEFUN AM_INTL_SUBDIR twice.
3401 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
3402 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
3403 strtoul.c.
3404 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
3405 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
3406 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
3407 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
3408 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
3409 * src/.cvsignore: Add *.output.
3411 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3412 gets copied to the output file.
3414 2004-04-28 Paul Eggert <eggert@twinsun.com>
3416 Get files from the gnulib and po repositories, instead of relying
3417 on them being in our CVS. Upgrade to latest versions of gnulib
3418 and Automake.
3420 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3421 * bootstrap: Bootstrap from gnulib and po repositories.
3422 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3423 * README-cvs: Document these changes. Remove version numbers from
3424 mentions of build tools, since they change so often. Mention Flex.
3426 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
3427 (gl_USE_SYSTEM_EXTENSIONS): Add.
3428 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
3429 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3430 does this for us.
3431 (AC_ISC_POSIX): Remove; we no longer support this
3432 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3433 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3434 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3435 Do not check for C89 headers, except for locale.h which is used
3436 by the Yacc library and must port to K&R hosts.
3437 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
3438 Do not check for C89 functions, except for setlocale which is
3439 used by the Yacc library.
3440 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
3441 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
3442 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,
3443 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE,
3444 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
3445 AM_GNU_GETTEXT): Remove; now done by:
3446 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
3447 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
3448 for us.
3450 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3451 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
3452 Define to empty, as gnulib.mk will do the rest for us.
3453 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
3454 for us.
3455 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
3456 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
3458 * src/files.c: Include gnulib's xstrndup.h.
3460 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
3461 (REALLOC): Use xnrealloc, for likewise.
3462 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
3463 (strnlen, memrchr): Remove decls; functions no longer used.
3464 Include <stpcpy.h>.
3466 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

3486 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
3487 Remove, as these files are now generated automatically
3488 by bootstrap or automake.
3490 * po/ChangeLog: Remove: all but one entry was a duplicate
3491 of this file, and I moved that 2000-11-02 entry here.
3493 * config/.cvsignore: Add Makefile, depcomp, install-sh.
3494 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

3503 unlocked-io.h, xalloc.h, xmalloc.c, xstrdup.c, xstrndup.c,
3504 xstrndup.h.

3508 stdbool.m4, stpcpy.m4, strnlen.m4, unlocked-io.m4, xalloc.m4.
3509 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
3510 * src/.cvsignore: Remove *_.c.
3513 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
3514 support it. (The latest stable gzip doesn't.)
3516 2004-04-27 Paul Eggert <eggert@twinsun.com>
3518 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
3519 case, as stos_ is now used by destructors due to the 2004-02-09
3520 change.
3522 Remove more K&R C support.
3523 * lib/libiberty.y (PARAMS): Remove. All uses removed.
3524 * lib/subpipe.c (errno): Remove decl.
3525 Include <stdlib.h> unconditionally.
3526 (EXIT_FAILURE): Remove macro.
3527 * src/complain.c (vfprintf, strerror): Remove.
3528 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
3529 unconditionally.
3530 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
3531 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
3532 (strchr, strspn, memchr): Remove decls.
3533 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
3534 unconditionally. Do not declare perror.
3535 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
3536 unconditionally.
3538 * src/complain.c (_): Remove useless defn, as system.h defines this.
3540 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
3541 with latest obstack.h.
3542 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
3543 to procedure types, as obstack.h now does that for us.
3544 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
3546 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
3547 so that this include file can stand alone.
3548 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
3549 does this now. Include subpipe.h first after config.h, to
3550 test whether it can stand alone.
3552 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
3553 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
3554 unused declaration.
3556 * tests/synclines.at (%union synch line): Put a dummy member in
3557 the union, because empty unions aren't allowed in C. Caught
3558 by GCC 3.4.0.
3560 2004-04-13 Jim Meyering <jim@meyering.net>
3562 * src/conflicts.c (conflicts_print): Correct format string typo:
3563 use `%%' to produce literal `%'. (trivial change)
3565 2004-03-30 Paul Eggert <eggert@twinsun.com>
3567 * src/getargs.c (version): Update copyright year to 2004.
3569 * data/c.m4 (b4_int_type): Use 'short int' rather than
3570 'short', and similarly for 'long', 'unsigned', etc.

3618 * src/conflicts.c (expected_sr_conflicts): Rename from
3619 expected_conflicts.
3620 (expected_rr_conflicts): Define.
3621 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
3622 for GLR parsers.
3623 Use expected_sr_conflicts in place of expected_conflicts.
3624 Warn if expected_rr_conflicts used in non-GLR parser.
3626 * doc/bison.texinfo: Add documentation for %expect-rr.
3628 2004-03-08 Paul Eggert <eggert@gnu.org>
3630 Add support for hex token numbers. Suggested by Odd Arild Olsen in
3631 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
3633 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
3634 in lalr1.cc.
3635 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
3636 * src/scan-gram.l (scan_integer): New function.
3637 ({int}): Use it.
3638 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
3639 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
3640 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
3641 Say "long int", not "long", for uniformity with GNU style.
3643 2004-02-25 Paul Eggert <eggert@twinsun.com>
3645 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
3646 compilers. This fixes a problem with Intel's C++ compiler being
3647 chatty, reported by Guido Trentalancia in
3648 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
3650 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
3652 Support %destructor and merge error locations in lalr1.cc.
3654 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
3655 (Parser::stos_): Define unconditionally.
3656 (Parser::destruct_): New method. Generate its body with
3657 b4_yydestruct_generate.

3660 token which are discarded.
3661 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
3662 error_start_ when erroneous token are discarded.
3663 (Parser::parse) <yyerrlab1>: Compute the location of the error
3664 token so that it covers all the discarded tokens.
3665 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
3666 it can be called with `%skeleton "lalr1.cc"', and do that.
3668 2004-02-02 Paul Eggert <eggert@twinsun.com>
3670 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
3671 $(top_srcdir)/lib and ../lib. This fixes a bug reported
3672 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
3673 There's no need to mention top_builddir since Automake does that
3674 for us.
3675 (INCLUDES): Remove, as Automake says it's obsolescent.
3676 Contents migrated into AM_CPPFLAGS as described above.
3677 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
3679 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3681 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
3682 (yyreportSyntaxError): Handle case where lookahead token is
3683 YYEMPTY.
3685 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
3687 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
3688 resulting parsers are compilable with C++.
3690 2003-12-23 Paul Eggert <eggert@twinsun.com>
3692 * config/depcomp, config/install-sh: Sync with Automake 1.8.
3693 * src/output.c (output_skeleton): Rename local var.
3694 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
3695 Bison tokens, as this runs afoul of the 2003-10-07 change that
3696 disallowed NUL bytes in character constants or string literals.
3698 * tests/local.at: Require Autoconf 2.59's Autotest.
3699 * tests/testsuite.at: Don't include local.at, since we now assume
3700 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
3701 including it.
3702 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
3703 multiple inclusion warnings.
3705 2003-12-02 Akim Demaille <akim@epita.fr>
3707 * doc/bison.texinfo (How Can I Reset the Parser): More about start
3708 conditions.
3709 From Bruno Haible.
3711 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
3713 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
3715 2003-10-07 Paul Eggert <eggert@twinsun.com>
3717 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
3718 if testsuite doesn't exist.
3720 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
3721 literals, unfortunately.
3722 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
3723 Complain about NUL bytes in character constants or string literals.
3725 2003-10-05 Paul Eggert <eggert@twinsun.com>
3727 * NEWS: Don't document %no-default-prec, as it's still
3728 too experimental.
3729 * doc/bison.texinfo: Document %no-default-prec only if
3730 the defaultprec flag is set. Normally it's not.
3732 2003-10-04 Paul Eggert <eggert@twinsun.com>
3734 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
3735 non-modifiable lvalue, instead of a modifiable one.
3736 * doc/bison.texinfo (Actions): Document that $$ can
3737 be assigned to. Do not claim that $$ and $N are
3738 array element references: user code should not rely on this.
3740 2003-10-01 Paul Eggert <eggert@twinsun.com>
3742 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
3743 (grammar_declaration): Use it.
3744 * src/scan-gram.l: New token %no-default-prec.
3745 * tests/conflicts.at: Revamp tests to use %no-default-prec.
3746 * NEWS, doc/bison.texinfo: Document the above.
3748 2003-10-01 Akim Demaille <akim@epita.fr>
3750 VCG no longer supports long_straight_phase.

3753 * src/print_graph.c (print_graph): Adjust.
3755 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
3756 and Paul Eggert <eggert@twinsun.com>
3758 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
3759 Table of Symbols): Document %default-prec.
3760 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.

3769 2003-09-30 Paul Eggert <eggert@twinsun.com>
3771 * tests/testsuite.at: Include local.at, not input.at, fixing
3772 a typo in the 2003-08-25 patch.
3774 2003-08-27 Akim Demaille <akim@epita.fr>
3776 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
3777 GCC warnings.
3779 2003-08-26 Akim Demaille <akim@epita.fr>
3781 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
3782 "<\#" to avoid magic from Gnus when posting parts of this script.
3784 2003-08-26 Akim Demaille <akim@epita.fr>
3786 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
3787 (Parser::parse): here.
3788 Adjust: nerrs and errstatus is now replaced by...
3789 (Parser::nerrs_, Parser::errstatus_): New.
3791 2003-08-25 Akim Demaille <akim@epita.fr>
3793 * config/announce-gen, Makefile.cfg: New.
3794 * Makefile.am: Adjust.
3795 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
3796 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
3798 2003-08-25 Akim Demaille <akim@epita.fr>
3800 When reducing initial empty rules, Bison parser read an initial
3801 location that is not defined. This results in garbage, and that
3802 affects Bison's own parser. Therefore we need (i) to extend Bison
3803 to support a means to initialize this location, and (ii) to use
3804 this CVS Bison to fix CVS Bison's parser.
3806 * src/reader.h, reader.c (epilogue_augment): Remove, replace
3807 with...
3808 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
3809 * src/parse-gram.y: Adjust.
3810 (%initial-action): New.
3811 (%error-verbose): Since we require CVS Bison, there is no reason
3812 not to use it.
3813 * src/scan-gram.l: Adjust.
3814 * src/Makefile.am (YACC): New, to make sure we use our own parser.
3815 * data/yacc.c (yyparse): Use b4_initial_action.
3817 2003-08-25 Akim Demaille <akim@epita.fr>
3819 * doc/bison.texinfo: Don't promote stdout for error messages.
3821 2003-08-25 Akim Demaille <akim@epita.fr>
3823 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
3824 From Alexandre Duret-Lutz.
3826 2003-08-25 Akim Demaille <akim@epita.fr>
3828 Version 1.875c.
3830 2003-08-25 Akim Demaille <akim@epita.fr>
3832 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
3833 Use them.
3835 2003-08-25 Akim Demaille <akim@epita.fr>
3837 * data/lalr1.cc (Parser::reduce_print_): New.
3838 Use it.
3840 2003-08-25 Akim Demaille <akim@epita.fr>
3842 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
3843 error recovery loops. This patch is based on
3844 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
3845 Also, augment the similarity between lalr1.cc and yacc.c.
3846 Note: the locations of error recovery rules are not correct yet.
3848 * data/lalr1.cc: Comment changes to augment the similarity between
3849 lalr1.cc and yacc.c.
3850 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
3851 (yyerrlab1): Remove, but where it used to be (now the bottom part of
3852 yyerrlab), when hitting EOF, pop the whole stack here instead of
3853 merely falling thru the default error handling mechanism.
3854 (yyerrorlab): New label, with the old contents of YYERROR,
3855 plus the following change: pop the stack of rhs corresponding
3856 to the production that invoked YYERROR. That is how Yacc
3857 behaves (required by POSIX).
3858 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
3859 fail.
3861 2003-08-25 Akim Demaille <akim@epita.fr>
3863 Tune local.at so that people can "autom4te -l autotest calc.at -o
3864 calc" for instance, to extract a sub test suite.
3866 * tests/testsuite.at: Move the initialization, Autotest version
3867 requirement, and AT_TESTED invocation into...
3868 * tests/local.at: here.
3869 * tests/testsuite.at: Include it for compatibility with Autoconf
3870 2.57.
3871 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
3872 be ignore.
3874 2003-08-04 Paul Eggert <eggert@twinsun.com>
3876 Rework code slightly to avoid gcc -Wtraditional warnings.
3877 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
3878 The returned value is now stored in *YY0. All callers changed.
3879 * src/output.c (merge_output): Adjust to the above change.
3881 2003-07-26 Paul Eggert <eggert@twinsun.com>
3883 * data/glr.c (YYASSERT): New macro.
3884 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
3885 yyresolveStates, yyprocessOneStack):
3886 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
3887 Derived from a suggestion by Frank Heckenbach.
3889 2003-07-25 Paul Eggert <eggert@twinsun.com>
3891 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
3892 for portability to K&R C (after ansi2knr, presumably). See
3893 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
3894 by Frank Heckenbach, though I have omitted the structure-initialization
3895 part of his glr-knr.diff patch since I recall that the Portable
3896 C Compiler didn't require that change.
3898 Let the user specify how to allocate and free memory.
3899 Derived from a suggestion by Frank Heckenbach in
3900 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
3901 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
3902 All uses of free, malloc, realloc changed to use these macros,
3903 and unnecessary casts removed.
3904 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
3906 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
3908 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
3909 use s.empty() rather than s == "" to test for empty string; see
3910 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
3911 (trivial change)
3913 2003-06-25 Akim Demaille <akim@epita.fr>
3915 * config/depcomp, config/install-sh: Update from masters.
3917 2003-06-20 Paul Eggert <eggert@twinsun.com>
3919 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
3920 and return properly parenthesized result.
3921 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
3922 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
3923 Remove unnecessary parentheses from uses.
3924 * doc/bison.texinfo (Location Default Action): Describe the
3925 conventions for parentheses.
3927 2003-06-19 Paul Eggert <eggert@twinsun.com>
3929 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
3930 yyreportTree): Do not assume that size_t is the same width as int,
3931 when printing sizes. Print sizes using an unsigned format.
3932 Problem reported by Frank Heckenbach in
3933 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
3935 Port to Forte Developer 7 C compiler.
3936 * data/glr.c (struct YYLTYPE): If locations are not being used,
3937 declare a single dummy member, as empty structs do not conform
3938 to the C standard.
3939 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
3940 the Forte Developer 7 C compiler complains that end-of-loop
3941 code is not reached.
3943 2003-06-17 Paul Eggert <eggert@twinsun.com>
3945 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
3946 avoid warnings from picky compilers about redefinition of PARAMS.
3948 2003-06-17 Paul Eggert <eggert@twinsun.com>
3950 Version 1.875b.
3952 * NEWS: Document 1.875b.
3954 * lib/bbitset.h: Do not include config.h; that's the includer's job.
3955 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
3956 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
3957 Don't use 'index' in comments, as it's a builtin fn on some hosts.
3958 * lib/bitset_stats.c: Include gettext.h unconditionally, as
3959 per recent gettext manual's suggestion.
3960 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
3961 Use prototypes, not old-style definitions.
3962 * lib/lbitset.c (lbitset_unused_clear): Likewise.
3963 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
3964 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
3965 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

3983 from libbitset.
3985 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
3986 `How Can I Reset @code{yyparse}', since texinfo does not allow
3987 arbitrary @ in node names.
3989 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
3990 shouldn't be needed according to the gettext 0.12.1 documentation
3991 but which seem to be needed anyway: codeset.m4 glibc21.m4
3992 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
3993 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

4014 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
4015 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
4016 the tests right now.
4017 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4018 yyerror are declared before use; C99 requires this.

4022 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
4023 first.
4024 (yyrecoverSyntaxError): Correct the logic for setting and testing
4025 yyerrState.
4026 Correct comment on handling EOF.
4027 Allow states with only a default reduction, rather than failing
4028 (I can't quite reconstruct why these were not allowed before).
4030 Fixes to avoid problem that $-N rules in GLR parsers can cause
4031 buffer overruns, corrupting state.
4033 * src/output.c (prepare_rules): Output max_left_semantic_context
4034 definition.
4035 * src/reader.h (max_left_semantic_context): New variable declaration.
4036 * src/scan-gram.l (max_left_semantic_context): Define.

4038 * data/glr.c (YYMAXLEFT): New definition.
4039 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
4040 (yyresolveAction): Ditto.
4042 Fixes to problems with location handling in GLR parsers reported by

4045 * data/glr.c (YYLTYPE): Make trivial if locations not used.
4046 (YYRHSLOC): Add parentheses, and define only if locations used.
4047 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if

4050 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4052 * tests/cxx-type.at: Exercise location information; update tests
4053 to differentiate output with and without locations.
4054 Remove forward declarations of yylex and yyerror---caused errors
4055 because default YYLTYPE not yet defined.
4056 Change semantic actions to compute strings, rather than printing
4057 them directly (to test proper passing of semantics values). Change
4058 output to prefix notation and update test data and expected results.
4059 (yylex): Track locations.
4060 (stmtMerge): Return value rather than printing, and include arguments
4061 in value.
4063 2003-06-03 Paul Eggert <eggert@twinsun.com>
4065 Avoid warnings generated by GCC 2.95.4 when Bison is
4066 configured with --enable-gcc-warnings.
4067 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
4068 yy::]b4_parser_class_name[::translate_,
4069 yy::Stack::operator[] (unsigned),
4070 yy::Stack::operator[] (unsigned) const,
4071 yy::Slice::operator[] (unsigned),
4072 yy::Slice::operator[] (unsigned) const):
4073 Rename local vars to avoid warnings.
4074 * tests/glr-regression.at (Improper handling of embedded actions
4075 and $-N in GLR parsers): Remove unused local variable from yylex.
4076 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4077 (void) as arg when not pure, since we now assume C89 when building
4078 Bison. Pacify GCC by using parameter.
4080 2003-06-02 Paul Eggert <eggert@twinsun.com>
4082 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4083 yy::Location::lines, yy::Location::columns): Rename arguments
4084 to avoid shadowing; this removes a warning generated by GCC 3.3.
4086 2003-06-01 Paul Eggert <eggert@twinsun.com>
4088 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4089 to g++, as GCC 3.3 complains if you do it.
4090 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4091 everything that WARNING_CFLAGS has, except omit warnings
4092 not suitable for C++.
4093 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4094 * tests/atlocal.in (CXXFLAGS): New var.
4095 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4097 Fix a GLR parser bug I reported in February; see
4098 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4099 The problem was that GLR parsers did not conform to the C standard,
4100 because actions like { $1 = $2 + $3; } expanded to expressions
4101 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4102 to a local variable. The C standard says that expressions
4103 like (var = f ()) + (var = f ()) have undefined behavior.
4104 Another problem was that GCC sometimes issues warnings that
4105 yyfill and its parameters are unused.
4107 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4108 as possibly unused.
4109 (yyfill): New function.
4110 (YYFILL): Use it.
4111 (yyuserAction): Change type of yynormal to bool, so that it matches
4112 the new yyfill signature. Mark it as possibly unused.
4115 Follow up on a bug I reported in February, where a Bison-generated
4116 parser can loop. Provide a test case and a fix for yacc.c. I
4117 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4118 The original bug report is in:
4119 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4121 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4122 macro's size was becoming unwieldy.
4123 (yyerrlab): Do not discard an empty lookahead symbol, as this
4124 might destroy garbage.
4125 (yyerrorlab): New label, with the old contents of YYERROR,
4126 plus the following change: pop the stack of rhs corresponding
4127 to the production that invoked YYERROR. That is how Yacc
4128 behaves, and POSIX requires this behavior.
4129 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4130 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4131 Define 'alarm' to do nothing if unistd.h is not available.
4132 Add a new rule "exp: '-' error;" to test the above change to
4133 data/yacc.c. Use 'alarm' to abort any test taking longer than
4134 10 seconds, as it's probably looping.
4135 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4136 Also, the new yacc.c generates two fewer diagnostics for an
4137 existing test.
4139 2003-05-24 Paul Eggert <eggert@twinsun.com>
4141 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4142 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4143 This fixes a problem reported by John Bowman when the Compaq/HP
4144 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4145 -ansi -Wall -gall).
4146 * data/yacc.c (union yyalloc): Likewise.
4147 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4149 Switch from 'int' to 'bool' where that makes sense.
4151 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
4152 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
4153 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
4154 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
4155 Return or accept bool, not int. All callers changed.
4156 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
4157 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
4158 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
4159 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
4160 bitset_or_and_cmp_): Likewise.
4161 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
4162 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
4163 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
4164 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
4165 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
4166 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
4167 bitset_stats_or_and_cmp): Likewise.
4168 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
4169 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
4170 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
4171 ebitset_xor_cmp): Likewise.
4172 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
4173 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
4174 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
4175 lbitset_xor_cmp): Likewise.
4176 * lib/bbitset.h: Include <stdbool.h>.
4177 (struct bitset_vtable): The following members now return bool, not
4178 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
4179 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
4180 or_and_cmp).
4181 * src/conflicts.c (count_rr_conflicts): Likewise.
4182 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
4183 All uses changed.
4184 * lib/ebitset.c (ebitset_obstack_init): Likewise.
4185 * lib/lbitset.c (lbitset_obstack_init): Likewise.
4186 * src/getargs.c (debug_flag, defines_flag, locations_flag,
4187 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4188 graph_flag): Likewise.
4189 * src/getargs.h (debug_flag, defines_flag, locations_flag,
4190 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4191 graph_flag): Likewise.
4192 * src/output.c (error_verbose): Likewise.
4193 * src/output.h (error_verbose): Likewise.
4194 * src/reader.c (start_flag, typed): Likewise.
4195 * src/reader.h (typed): Likewise.
4196 * src/getargs.c (LOCATIONS_OPTION): New constant.
4197 (long_options, getargs): Use it.
4198 * src/lalr.c (build_relations): Use bool, not int.
4199 * src/nullable.c (nullable_compute): Likewise.
4200 * src/print.c (print_reductions): Likewise.
4201 * src/tables.c (action_row, pack_vector): Likewise.
4202 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
4203 * src/output.c (prepare): Use it.
4204 * src/output.c (token_definitions_output,
4205 symbol_destructors_output, symbol_destructors_output): Use string,
4206 not boolean integer, to keep track of whether to output separator.
4207 * src/print_graph.c (print_core): Likewise.
4208 * src/state.c (state_rule_lookaheads_print): Likewise.
4210 * config/install-sh: Sync from automake 1.7.5.
4212 2003-05-14 Paul Eggert <eggert@twinsun.com>
4214 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4215 semicolon after a grammar declaration, in the interest of possible
4216 future changes to the Bison input language.
4217 Do not allow a stray semicolon at the start of the grammar.
4218 (rhses.1): Allow one or more semicolons after any rule, including
4219 just before "|" as required by POSIX.
4220 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4221 grammar.
4223 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4225 %parse-param support for lalr1.cc.
4227 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4228 b4_cc_constructor_calls, b4_cc_constructor_call,
4229 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4230 definitions.
4231 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4232 parse-param arguments.
4233 (yy::b4_parser_class_name): Declare instance variables to
4234 hold parse-param arguments.
4235 * tests/calc.at: s/value/semantic_value/ because value clashes
4236 with a member of yy::b4_parser_class_name. Adjust C++ code
4237 to handle %parse-param. Enable %parse-param test in C++.
4239 2003-05-12 Paul Eggert <eggert@twinsun.com>
4241 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4242 English a bit. Fix fclose typo. Change "const char" to "char
4243 const", and use ANSI C rather than K&R for "main". Suggest
4244 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4245 and suggest yy_switch_to_buffer.
4247 2003-05-05 Paul Eggert <eggert@twinsun.com>
4249 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4250 C89. This avoids a diagnostic on compilers that define __STDC__
4251 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4252 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4254 2003-05-03 Paul Eggert <eggert@twinsun.com>
4256 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
4257 Do not overrun array bounds.
4258 This should fix a bug reported today by Olatunji Oluwabukunmi in
4259 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
4261 2003-04-29 Akim Demaille <akim@epita.fr>
4263 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4264 * src/getargs.c, src/getargs.h: here, as bool, not int.
4265 (nondeterministic_parser): New.
4266 * src/parse-gram.y, src/scan-gram.l: Support
4267 %nondeterministic-parser.
4268 * src/output.c (prepare): Use nondeterministic_parser instead
4269 of glr_parser where appropriate.
4270 * src/tables.c (conflict_row, action_row, save_row)
4271 (token_actions, token_actions, pack_vector): Ditto.
4273 2003-04-29 Akim Demaille <akim@epita.fr>
4275 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4277 2003-04-29 Akim Demaille <akim@epita.fr>
4279 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4280 with %pure-parser and %locations to exercise the patch from Yakov
4281 Markovitch below.
4283 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4285 * data/yacc.c: (b4_lex_param): Corrected for the case where
4286 %lex-param is provided and %pure-parser isn't.
4288 2003-04-27 Paul Eggert <eggert@twinsun.com>
4290 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4291 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4292 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4293 if it is not defined.
4294 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4296 2003-04-26 Paul Eggert <eggert@twinsun.com>
4298 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4299 Declare to be of type suitable for the ninf value itself, not of
4300 type suitable for the corresponding table, since the latter might
4301 be unsigned but the ninf value might be negative. This fixes a
4302 bug reported by Alexandre Duret-Lutz in
4303 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4305 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4306 invokes it. We shouldn't invoke it twice because it will attempt
4307 to put error.o in the archive twice. This fixes a glitch reported
4308 by Martin Mokrejs in
4309 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4311 2003-04-21 Paul Eggert <eggert@twinsun.com>
4313 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4314 to gnulib.
4316 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4318 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4319 Fix obvious typo that results in uncompilable GLR parsers
4320 when both %pure-parser and %locations are used. (trivial change)
4322 2003-04-17 Paul Eggert <eggert@twinsun.com>
4324 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4325 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4326 Do not insert the expected token via unput, as this runs afoul
4327 of a POSIX-compatibility bug in flex 2.5.31.
4328 All uses changed to BEGIN the parent state,
4329 since we no longer insert the expected token via unput.
4330 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4331 that is no longer emitted after the above change.
4333 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4334 the first one. This change is from Paul Hilfinger, and it fixes
4335 regression reported by Werner Lemberg in
4336 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4338 (resolve_sr_conflict): Don't invoke state_errs_set
4339 unless one or more tokens have been explicitly made errors.
4340 Otherwise, the above change causes Bison to abort.
4342 * tests/existing.at (GNU pic Grammar): New test case, taken from
4343 Lemberg's email.
4345 2003-03-31 Akim Demaille <akim@epita.fr>
4347 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4349 2003-03-31 Akim Demaille <akim@epita.fr>
4351 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4352 output.
4354 2003-03-31 Akim Demaille <akim@epita.fr>
4356 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4357 From Paul Hilfinger.
4359 2003-03-29 Akim Demaille <akim@epita.fr>
4361 * m4/error.m4: Do not put under dynamic conditions some code which
4362 expansion is under static control.
4364 2003-03-29 Akim Demaille <akim@epita.fr>
4366 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4368 2003-03-29 Akim Demaille <akim@epita.fr>
4370 * doc/bison.texinfo (Strings are Destroyed): New.
4372 2003-03-13 Paul Eggert <eggert@twinsun.com>
4374 * .cvsignore: Add configure.lineno.
4375 * src/.cvsignore: Add yacc.
4376 * tests/.cvsignore: Add testsuite.log.
4377 * doc/fdl.texi: Sync with latest FSF version.
4379 2003-03-12 Paul Eggert <eggert@twinsun.com>
4381 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4382 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4383 cursor, instead of leaving it undefined. This fixes a bug
4384 reported by Tim Van Holder in
4385 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4386 * tests/input.at (Torturing the Scanner): Test the scanner on
4387 an empty input file, which was Tim Van Holder's test case.
4389 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4390 <sys/resource.h> can be included, include sys/time.h and
4391 sys/times.h first, if available. This works around the SunOS
4392 4.1.4 porting bug reported by Bruce Becker in
4393 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4395 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4396 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4397 AC_HEADER_SYS_WAIT.
4399 Merge changes from gnulib. This was prompted because the CVS
4400 snapshot didn't build on Solaris 7 due to strnlen problems.
4402 These changes need to be merged back into gnulib:
4403 * lib/hash.c: Include <stdbool.h> unconditionally.
4404 * m4/onceonly.m4 (m4_quote): New macro.
4405 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4406 Quote AC_FOREACH variable-expansions properly.
4407 The 2003-01-03 obstack.h change also needs merging.
4408 {end of changes requiring merging}
4410 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
4411 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
4412 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
4413 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
4414 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
4415 New files, imported from gnulib.
4416 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
4417 above.
4419 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
4420 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
4421 gnulib sources.
4423 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
4424 Add.
4425 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
4426 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
4427 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
4428 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
4429 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
4430 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
4431 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
4432 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
4433 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
4434 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
4435 (jm_PREREQ_ARGMATCH): Remove.
4436 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
4437 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
4439 * src/system.h: Include <stdbool.h> unconditionally.
4441 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
4442 assuming at least C89 in the bitset code for some time now.
4444 2003-03-03 Akim Demaille <akim@epita.fr>
4446 * ro.po: New.
4448 2003-03-02 Akim Demaille <akim@epita.fr>
4450 * doc/bison.texinfo (Table of Symbols): Reactivate the
4451 documentation for %lex-param, and %parse-param.
4453 2003-03-02 Akim Demaille <akim@epita.fr>
4455 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4456 generate verbose error messages.
4457 Use the number of tokens as an upper bound in yytname, as it
4458 cannot be a non terminal.
4460 2003-03-02 Akim Demaille <akim@epita.fr>
4462 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4463 message.
4465 2003-03-02 Akim Demaille <akim@epita.fr>
4467 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
4468 Use them to exercise yycheck overrun.
4469 Based on Andrew Suffield's grammar.
4471 2003-03-02 Akim Demaille <akim@epita.fr>
4473 Create tests/local.at for Bison generic testing macros.
4475 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
4476 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
4477 This new file.
4478 * tests/calc.at (AT_CHECK_CALC): Adjust.
4479 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
4480 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
4481 * tests/local.at: here.
4482 (AT_COMPILE_CXX): Tags the tests using it as c++.
4483 Ignore the test if CXX is not functional.
4485 2003-03-01 Paul Eggert <eggert@twinsun.com>
4487 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
4488 not loc->end, since loc->end might contain garbage and this leads
4489 to undefined behavior on some platforms.
4490 (id_loc, token_start): Use (IF_LINTed) initial values that do not
4491 depend on *loc, so that the reader doesn't give the the false
4492 impression that *loc is initialized.
4493 (<INITIAL>"%%"): Do not bother setting code_start, since its value
4494 does not survive the return.
4496 2003-03-01 Akim Demaille <akim@epita.fr>
4498 * src/scan-gram.l (code_start): Always initialize it when entering
4499 into yylex, as SC_EPILOGUE is activated *before* the corresponding
4500 yylex invocation. An alternative would be making it static, but
4501 then it starts with the second %%'s beginning, instead of its end.
4503 2003-02-28 Paul Eggert <eggert@twinsun.com>
4505 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
4506 around a UnixWare 7.1.1 porting bug reported by John Hughes in
4507 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
4509 2003-02-26 Paul Eggert <eggert@twinsun.com>
4511 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
4512 Remove Sequent/Pyramid discussion (nobody uses them any more).
4513 Merge VMS and MS-DOS discussion; these ports may well be dead
4514 but let's keep mentioning them for now. Put <> around email
4515 addresses. Add copyright notice.
4517 2003-02-24 Paul Eggert <eggert@twinsun.com>
4519 * data/glr.c (yy_reduce_print): yylineno -> yylno,
4520 to avoid collision with flex use of yylineno.
4521 Problem reported by Bruce Lilly in
4522 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
4523 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
4524 * data/yacc.c (yy_reduce_print): Likewise.
4526 * config/depcomp: Sync with Automake 1.7.3.
4528 2003-02-21 Akim Demaille <akim@epita.fr>
4530 * data/lalr1.cc: Use temporary variables instead of casts to
4531 change integer types.
4532 Suggested by Paul Eggert.
4534 2003-02-21 Akim Demaille <akim@epita.fr>
4536 * doc/bison.texinfo: Use "location" consistently to refer to @n,
4537 to avoid confusions with lalr1.cc's notion of Position.
4538 Suggested by Paul Eggert.
4540 2003-02-20 Akim Demaille <akim@epita.fr>
4542 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
4543 before initial_columns.
4544 (location.hh): Use consistent variable names when defining the
4545 operator<<.
4546 Use "last" so that we subtract from Positions, not from unsigned.
4548 2003-02-20 Akim Demaille <akim@epita.fr>
4550 * data/lalr1.cc (position.hh): New subfile, including the extended
4551 and Doxygen'ed documentation of class Position.
4552 (location.hh): Use it.
4553 Document a` la Doxygen.
4554 With the help of Benoit Perrot.
4556 2003-02-20 Akim Demaille <akim@epita.fr>
4558 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
4559 AT_YACC_IF.
4560 Redefine AT_YYERROR_SEES_LOC_IF using it.
4561 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
4562 not defined.
4563 Don't use the location in yy::Parser::error_ and
4564 yy::Parser::print_ when not %locations.
4565 Activate more lalr1.cc tests.
4567 2003-02-19 Akim Demaille <akim@epita.fr>
4569 * data/lalr1.cc: When displaying a line number, be sure to make it
4570 an int.
4572 2003-02-19 Akim Demaille <akim@epita.fr>
4574 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
4575 Remove, useless.
4576 (YYABORT, YYACCEPT, YYERROR): New.
4577 * tests/calc.at: Renable the lalr1.cc test.
4579 2003-02-19 Akim Demaille <akim@epita.fr>
4581 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
4582 error recovery, mixing with/without pops and discarding of the
4583 lookahead.
4584 Exercise YYERROR.
4585 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
4587 2003-02-17 Paul Eggert <eggert@twinsun.com>
4589 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
4590 * tests/testsuite.at (AT_COMPILE): Use them.
4591 This fixes the testsuite problem reported by Robert Lentz in
4592 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
4594 2003-02-12 Paul Eggert <eggert@twinsun.com>
4596 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
4597 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
4598 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
4599 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
4600 Check for malloc failure, for consistency with yacc.c.
4601 (yytname_size): Remove, for consistency with yacc.c.
4603 The bug still remains in data/lalr1.cc, as I didn't have time
4604 to fix it there.
4606 2003-02-06 Akim Demaille <akim@epita.fr>
4608 * configure.ac (GXX): Rename as...
4609 (CXX): this, to keep the original Autoconf semantics.
4610 Require 2.57.
4611 * data/lalr1.cc: Fix b4_copyright invocations.
4612 If YYDEBUG is not defined, don't depend upon name_ being defined.
4613 (location.hh): Include string and iostream.
4614 (Position::filename): New member.
4615 (Position::Position ()): New.
4616 (operator<< (Position)): New.
4617 (operator- (Position, int)): New.
4618 (Location::first, Location::last): Rename as...
4619 (Location::begin, Location::end): these, to mock the conventional
4620 iterator names.
4621 (operator<< (Location)): New.
4622 * tests/atlocal.in (CXX): New.
4623 * tests/testsuite.at (AT_COMPILE_CXX): New.
4624 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
4625 locations in a more synthetic way.
4626 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
4627 lalr1.cc is used.
4628 Adjust the C locations to match those from Emacs: first column is
4629 column 0.
4630 Change all the expected results.
4631 Conform to the GCS: simplify the locations when applicable.
4632 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
4633 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
4634 these CPP macros with the m4 macros new defined by...
4635 (AT_CHECK_PUSHDEFS): this, i.e.:
4636 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
4637 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
4638 New macros.
4639 (AT_CHECK_POPDEFS): Undefine them.
4640 (AT_CHECK_CALC_LALR1_CC): New.
4641 Use it for the first lalr1.cc test.
4643 2003-02-04 Akim Demaille <akim@epita.fr>
4645 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
4646 Location as is defined.
4648 2003-02-04 Akim Demaille <akim@epita.fr>
4650 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
4651 name_ being defined.
4653 2003-02-03 Paul Eggert <eggert@twinsun.com>
4655 * src/gram.h (start_symbol): Remove unused decl.
4657 Use more-consistent naming conventions for local vars.
4659 * src/derives.c (derives_compute): Change type of local var from
4660 int to rule_number.
4661 * src/gram.c (grammar_rules_partial_print): Likewise.
4662 * src/print.c (print_core): Likewise.
4663 * src/reduce.c (reduce_grammar_tables): Likewise.
4665 * src/gram.c (grammar_dump): Change name of item_number *
4666 local var from r to rp.
4667 * src/nullable.c (nullable_compute): Likewise.
4669 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
4671 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
4672 for symbol or symbol_number var.
4673 * src/reader.c (grammar_start_symbol_set): Likewise.
4674 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
4675 Likewise.
4676 * src/state.c (transitions_to): Likewise.
4677 * src/state.h: Likewise.
4678 * src/tables.c (symbol_number_to_vector_number): Likewise.
4680 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
4681 char * var.
4683 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
4684 var.
4686 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
4687 var.
4689 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
4690 Use str, not s, for char * var. Use ch, not c, for character var.
4691 Use size for size var.
4693 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
4694 char * var.
4695 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
4696 uniqstr var.
4697 * src/uniqstr.h: Likewise.
4699 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
4700 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
4701 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
4702 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
4703 param to have same name as that of enum, so that we don't use
4704 "s" to stand for a non-state.
4706 2003-02-02 Akim Demaille <akim@epita.fr>
4708 * src/scan-skel.l: Scan more than one inert character per yylex
4709 invocation.
4711 2003-02-01 Paul Eggert <eggert@twinsun.com>
4713 Version 1.875a.
4715 * po/LINGUAS: Add ms.
4717 2003-01-30 Akim Demaille <akim@epita.fr>
4719 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
4721 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4723 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
4724 of $1.
4726 Changes in response to error report by S. Eken: GLR mode does not
4727 handle negative $ indices or $ indices in embedded rules correctly.
4728 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
4730 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
4731 (b4_rhs_location): Ditto.
4732 (yyfill): New function to copy from stack tree into array
4733 incrementally.
4734 (yyuserAction): Modify to allow incremental move of semantic values
4735 to rhs array when in GLR mode.
4736 Define YYFILL to use in user-defined actions to fill semantic array
4737 as needed.
4738 Remove dummy use of yystack, as there is now a guaranteed use.
4739 (yydoAction): Modify to allow incremental move of semantic values
4740 to rhs array when in GLR mode.
4741 (yyresolveAction): Ditto.
4742 (yyglrShiftDefer): Update comment.
4743 (yyresolveStates): Use X == NULL for pointers, not !X.
4744 (yyglrReduce): Ditto.
4745 (yydoAction): Ditto
4747 * tests/glr-regr1.at: Rename to ...
4748 * tests/glr-regression.at: Add new regression test for the problems
4749 described above (adapted from S. Eken).
4750 Update copyright notice.
4751 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
4752 * tests/Makefile.am: Ditto.
4754 2003-01-28 Paul Eggert <eggert@twinsun.com>
4756 * data/lalr1.cc: Do not use @output_header_name@ unless
4757 b4_defines_flag is set. This fixes two bugs reported by
4758 Tim Van Holder in
4759 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
4760 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
4762 2003-01-21 Paul Eggert <eggert@twinsun.com>
4764 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
4765 we don't need to worry about yyerrlab1 being reported as an
4766 "unused label" by non-GCC C compilers. The downside is that if
4767 locations are used then a couple of statements are duplicated each
4768 time YYERROR is invoked, but the upside is that the warnings
4769 should vanish.
4770 (yyerrlab1): Move code to YERROR.
4771 (yyerrlab2): Remove. Change uses back to yyerrlab1.
4772 This reverts some of the 2002-12-27 change.
4774 2003-01-17 Paul Eggert <eggert@twinsun.com>
4776 * src/output.c (symbol_printers_output): Fix typo that led
4777 to core dump. Problem reported by Antonio Rus in
4778 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
4780 2003-01-13 Akim Demaille <akim@epita.fr>,
4781 Quoc Peyrot <chojin@lrde.epita.fr>,
4782 Robert Anisko <anisko_r@lrde.epita.fr>
4784 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
4785 when the stacks contain one element, as the loop would otherwise
4786 free the last state, and then use the top state (the one we just
4787 popped). This means that the initial elements will not be freed
4788 explicitly, as is the case in yacc.c; it is not a problem, as
4789 these elements have fake values.
4791 2003-01-11 Paul Eggert <eggert@twinsun.com>
4793 * NEWS: %expect-violations are now just warnings, reverting
4794 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
4795 bootstrapping problem reported by Matthias Klose; see
4796 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
4797 * src/conflicts.c (conflicts_print): Likewise.
4798 * tests/conflicts.at (%expect not enough, %expect too much,
4799 %expect with reduce conflicts): Likewise.
4800 * doc/bison.texinfo (Expect Decl): Document this. Also mention
4801 that the warning is enabled if the number of conflicts changes
4802 (not necessarily increases).
4804 * src/getargs.c (version): Update copyright year.
4806 2003-01-09 Akim Demaille <akim@epita.fr>
4808 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
4810 2003-01-08 Paul Eggert <eggert@twinsun.com>
4812 * Makefile.maint (WGETFLAGS):
4813 New macro, containing "-C off" to disable proxy caches.
4814 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
4815 (rel-check): Use $(WGET) instead of wget.
4817 2003-01-06 Paul Eggert <eggert@twinsun.com>
4819 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
4820 the GLR paper of Scott, Johnstone and Hussain.
4822 2003-01-04 Paul Eggert <eggert@twinsun.com>
4824 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
4825 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
4826 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
4827 (EXTRA_LIBRARIES): New var, for liby.a.
4828 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
4829 (EXTRA_SCRIPTS): New var, for yacc.
4831 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
4832 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
4833 Problem reported by Nelson H. F. Beebe.
4835 2003-01-03 Paul Eggert <eggert@twinsun.com>
4837 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
4838 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
4839 when compiling Bison 1.875's `bitset bset = obstack_alloc
4840 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
4842 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
4843 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
4844 grow to a huge size with typical invocation.
4846 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
4847 Use the pattern recommended by Autoconf 2.57, except also protect
4848 against double-definition.
4849 * src/system.h: Likewise.
4850 Portability issues reported by Nelson H. F. Beebe.
4852 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
4853 All uses changed. Provide a definition in both C and C++.
4854 (yytrue, yyfalse): Define even if defined (__cplusplus).
4856 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
4857 Reported by Nelson H. F. Beebe.
4859 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
4861 2003-01-02 Paul Eggert <eggert@twinsun.com>
4863 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
4864 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
4865 Bug reported by Nelson H. F. Beebe.
4867 2003-01-01 Paul Eggert <eggert@twinsun.com>
4869 * Version 1.875.
4871 2002-12-30 Paul Eggert <eggert@twinsun.com>
4873 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
4874 Moved here from...
4875 (<INITIAL>","): Here. This causes stray "," to be treated
4876 more uniformly.
4878 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
4879 last brace in braced code when not in Yacc mode, for compatibility
4880 with Bison 1.35. This resurrects the 2001-12-15 patch to
4881 src/reader.c.
4883 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
4884 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
4886 2002-12-28 Paul Eggert <eggert@twinsun.com>
4888 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
4889 that of SYM's type. This fixes Debian bug 168069, reported by
4890 Thomas Olsson.
4892 2002-12-28 Paul Eggert <eggert@twinsun.com>
4894 Version 1.75f.
4896 Switch back to the Yacc style of conflict reports, undoing some
4897 of the 2002-07-30 change.
4898 * doc/bison.texinfo (Understanding): Use Yacc style for
4899 conflict reports. Also, use new way of locating rules.
4900 * src/conflicts.c (conflict_report):
4901 Renamed from conflict_report_yacc, removing the old
4902 'conflict_report'. Translate the entire conflict report at once,
4903 so that we don't assume that "," has the same interpretation in
4904 all languages.
4905 (conflicts_output): Use Yacc-style conflict report for each state,
4906 instead of our more-complicated style.
4907 (conflicts_print): Use Yacc-style conflict report, except print
4908 the input file name when not emulating Yacc.
4909 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
4910 Conflicted Reduction, %expect not enough, %expect too much,
4911 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
4912 * tests/existing.at (GNU Cim Grammar): Likewise.
4913 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
4915 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
4916 fatal): Don't invoke fflush; it's not needed and it might even be
4917 harmful for stdout, as stdout might not be open.
4918 * src/reduce.c (reduce_print): Likewise.
4920 2002-12-27 Paul Eggert <eggert@twinsun.com>
4922 Fix a bug where error locations were not being recorded correctly.
4923 This problem was originally reported by Paul Hilfinger in
4924 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
4926 * data/yacc.c (yyparse): New local var yylerrsp, to record the
4927 top of the location stack's error locations.
4928 (yyerrlab): Set it. When discarding a token, push its location
4929 onto yylerrsp so that we don't lose track of the error's end.
4930 (yyerrlab1): Now is only the target of YYERROR, so that we can
4931 properly record the location of the action that failed. For GCC
4932 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
4933 GCC warning about yyerrlab1 being unused if YYERROR is unused.
4934 (yyerrlab2): New label, which yyerrlab now falls through to.
4935 Compute the error's location by applying YYLLOC_DEFAULT to
4936 the locations of all the symbols that went into the error.
4937 * doc/bison.texinfo (Location Default Action): Mention that
4938 YYLLOC_DEFAULT is also invoked for syntax errors.
4939 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
4940 Error locations include the locations of all the tokens that were
4941 discarded, not just the last token.
4943 2002-12-26 Paul Eggert <eggert@twinsun.com>
4945 * src/files.c: Include quote.h.
4946 (compute_output_file_names): Warn if we detect conflicting
4947 outputs to the same file. This should catch the misunderstanding
4948 exemplified by Debian Bug 165349, reported by Bruce Stephens..
4950 * src/conflicts.c (conflicts_print): If the user specifies
4951 "%expect N", report an error if there are any reduce/reduce
4952 conflicts. This is what the manual says should happen.
4953 This fixes Debian bug 130890, reported by Anthony DeRobertis.
4954 * tests/conflicts.at (%expect with reduce conflicts): New test.
4956 Don't use m4_include on relative file names, as it doesn't work as
4957 desired if there happens to be a file with that name under ".".
4959 * m4sugar/version.m4: Remove; it was included but it wasn't used.
4960 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
4961 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
4962 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
4963 * src/output.c (output_skeleton): Use full path names when
4964 specifying a file to include; don't rely on include path, as
4965 it's unreliable when the working file contains a file with
4966 that name.
4968 2002-12-25 Paul Eggert <eggert@twinsun.com>
4970 Remove obsolete references to bison.simple and bison.hairy.
4971 Problem mentioned by Aubin Mahe in
4972 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
4973 * data/glr.c: Comment fix.
4974 * doc/bison.1: Remove references. Also, mention "yacc".
4976 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
4977 with -g option.
4979 * src/parse-gram.y (declaration): Use enum "report_states" rather
4980 than its numeric value 1.
4982 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
4983 opening a new one. This fixes Debian bug 165349, reported by
4984 Bruce Stephens.
4986 2002-12-24 Paul Eggert <eggert@twinsun.com>
4988 Version 1.75e.
4990 * Makefile.maint (cvs-update): Don't assume that the shell
4991 supports $(...), as Solaris sh doesn't.
4993 * src/parse-gram.y (lloc_default): Remove test for empty
4994 nonterminals at the end, since it didn't change the result.
4996 2002-12-24 Paul Eggert <eggert@twinsun.com>
4998 If the user does not define YYSTYPE as a macro, Bison now declares it
4999 using typedef instead of defining it as a macro. POSIX requires this.
5000 For consistency, YYLTYPE is also declared instead of defined.
5002 %union directives can now have a tag before the `{', e.g., the
5003 directive `%union foo {...}' now generates the C code
5004 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5005 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5006 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5007 instead of `yyltype'.
5009 `yystype' and `yyltype' are now obsolescent macros instead of being
5010 typedefs or tags; they are no longer documented and will be
5011 withdrawn in a future release.
5013 * data/glr.c (b4_location_type): Remove.
5014 (YYSTYPE): Renamed from yystype.
5015 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5016 (struct YYLTYPE): Renamed from struct yyltype.
5017 (YYLTYPE): Renamed from yyltype.
5018 (yyltype, yystype): New (and obsolescent) macros,
5019 for backward compatibility.
5020 * data/yacc.c: Likewise.
5022 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5023 does not specify a union tag. This is for compatibility with
5024 Solaris 9 yacc.
5026 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5027 const *, since it is now modified by stripping surrounding { }.
5028 (current_braced_code): Remove.
5029 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5030 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5031 trailing " {...}". Now of type <chars>.
5032 (grammar_declaration): Adjust to bundled tokens.
5033 (code_content): Remove; stripping is now done by add_param.
5034 (print_token_value): Print contents of bundled tokens.
5035 (token_name): New function.
5037 * src/reader.h (braced_code, current_braced_code): Remove.
5038 (token_name): New decl.
5040 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5041 token_type, not braced_code code_kind. All uses changed.
5042 (SC_PRE_CODE): New state, for scanning after a keyword that
5043 has (or usually has) an immediately-following braced code.
5044 (token_type): New local var, to keep track of which token type
5045 to return when scanning braced code.
5046 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5047 <INITIAL>"%parse-param", <INITIAL>"%printer",
5048 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5049 instead of returning a token type immediately.
5050 (<INITIAL>"{"): Set token type.
5051 (<SC_BRACED_CODE>"}"): Use it.
5052 (handle_action_dollar, handle_action_at): Now returns bool
5053 indicating success. Fail if ! current_rule; this prevents a core dump.
5054 (handle_symbol_code_dollar, handle_symbol_code_at):
5055 Remove; merge body into caller.
5056 (handle_dollar, handle_at): Complain in invalid contexts.
5058 * NEWS, doc/bison.texinfo: Document the above.
5059 * NEWS: Fix years and program names in copyright notice.
5061 2002-12-17 Paul Eggert <eggert@twinsun.com>
5063 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5064 Reporting, Table of Symbols): Omit mentions of %lex-param and
5065 %parse-param from the documentation for now.
5067 2002-12-15 Paul Eggert <eggert@twinsun.com>
5069 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5070 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5071 lookahead symbol, and which sets yychar in parser actions) and it
5072 disagreed with the Bison documentation. Bug
5073 reported by Andrew Walrond.
5075 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5076 as the caller now does that.
5077 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5078 (YYEMPTY): Parenthesize right hand side, since others use it.
5079 (yyparse): Don't assume that our generated code is the only code
5080 that sets yychar.
5082 2002-12-13 Paul Eggert <eggert@twinsun.com>
5084 Version 1.75d.
5086 POSIX requires a "yacc" command.
5087 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
5088 (MOSTLYCLEANFILES): Add yacc.
5089 (yacc): New rule.
5090 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
5091 as an alias for bison y.
5093 * po/LINGUAS: Add da.
5095 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
5096 problem with latest <getopt.h>.
5097 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
5099 * doc/fdl.texi: Upgrade to 1.2.
5100 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
5101 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
5102 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
5103 gnulib.
5104 * config/install-sh: Sync with autotools.
5106 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
5107 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5108 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
5109 locations are requested.
5110 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
5111 locations are requested.
5113 2002-12-12 Paul Eggert <eggert@twinsun.com>
5115 Remove unportable casts and storage allocation tricks.
5116 While we're at it, remove almost all casts, since they
5117 usually aren't needed and are a sign of trouble.
5119 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5121 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5122 the pointer DSET returned by malloc; this isn't portable.
5123 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
5124 Similarly for DERIVES.
5125 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
5126 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
5127 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
5129 * src/derives.c (derives_compute): Do not bother invoking
5130 int_of_rule_number, since rule numbers are integers.
5132 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
5133 rather than XMALLOC (char, N).
5135 * src/files.c (filename_split): Rewrite to avoid cast.
5137 * src/gram.h (symbol_number_as_item_number,
5138 item_number_as_symbol_number, rule_number_as_item_number,

5140 Now inline functions rather than macros, to avoid casts.
5141 * src/state.h (state_number_as_int): Likewise.
5142 * src/tables.c (state_number_to_vector_number,
5143 symbol_number_to_vector_number): Likewise.
5145 * src/gram.h (int_of_rule_number): Remove; no longer used.
5147 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
5148 since the resulting storage is always stored into.
5150 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
5151 where it's needed.
5153 * src/muscle_tab.c (muscle_m4_output):
5154 Now inline. Return bool, not int.
5155 * src/state.c (state_compare): Likewise.

5165 symbol_check_alias_consistency_processor, symbol_pack_processor,
5166 symbol_translation_processor, hash_symbol_comparator,
5167 hash_symbol_hasher): Likewise.
5168 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5169 * src/muscle_tab.c (muscles_m4_output):
5170 Use new functions instead of casting old functions unportably.
5171 * src/state.c (state_hash_new): Likewise.
5172 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5173 symbols_token_translations_init):
5174 Likewise.
5175 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5177 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5178 var instead of casting to long, to avoid casts.
5179 (prepare_states): Use MALLOC rather than alloca, so that we don't
5180 have to worry about alloca.
5181 * src/state.c (state_hash_lookup): Likewise.
5183 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5184 local var instead of casting to unsigned char, to avoid casts.
5186 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
5187 STATE_ALLOC): Remove.
5188 (transitions_new, errs_new, reductions_new, state_new): Use malloc
5189 rather than calloc, and use offsetof to avoid allocating slightly
5190 too much storage.
5191 (state_new): Initialize all members.
5193 * src/state.c (state_hash): Use unsigned accumulator, not signed.
5195 * src/symtab.c (symbol_free): Remove; unused.
5196 (symbol_get): Remove cast in lhs of assignment.
5197 (symbols_do): Now static. Accept generic arguments, not
5198 hashing-related ones.
5200 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
5201 (symbol_processor): Remove.
5202 (symbols_do): Remove decl; now static.
5204 * src/system.h (alloca): Remove; decl no longer needed.
5205 (<stddef.h>): Include, for offsetof.
5206 (<inttypes.>, <stdint.h>): Include if available.
5207 (uintptr_t): New type, if system lacks it.
5208 (CALLOC, MALLOC, REALLOC): New macros.
5209 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5210 new macros.
5212 * src/tables.c (table_size): Now int, to pacify GCC.
5213 (table_grow, table_ninf_remap): Use signed table size.
5214 (save_row): Don't bother initializing locals when not needed.
5215 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.

5223 * src/getargs.c (getargs): Don't assume EOF == -1.
5225 2002-12-09 Paul Eggert <eggert@twinsun.com>
5227 Change identifier spellings to avoid collisions with names
5228 that are reserved by POSIX.
5230 Don't use names ending in _t, since POSIX reserves them.
5231 For consistency, remove _e and _s endings -- they're weren't
5232 needed to remove ambiguity. All uses changed.
5233 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5234 turn was just renamed from struniq_t.
5235 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
5236 which in turn was just renamed from struniq_processor_t.

5305 * tests/calc.at (_AT_DATA_CALC_Y, Simple LALR Calculator):
5306 Rename value_t -> value.
5307 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
5308 value_t_as_yystype -> value_as_yystype.
5310 Don't include <errno.h> in the mainstream code, since it
5311 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5312 * lib/get-errno.c, lib/get-errno.h: New files.
5313 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

5323 (TAB_EXT): Renamed from EXT_TAB.
5324 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
5326 Avoid str[a-z]*, since <string.h> reserves that name space.

5328 likewise for "STRUNIQ" and "UNIQSTR".
5329 * src/uniqstr.c: Renamed from src/struniq.c.
5330 * src/uniqstr.h: Renamed from src/struniq.h.

5368 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5371 Sort include-file uses.
5373 Reorder all include files under src to be in the order "system.h".
5374 then the ../lib include files in angle brackets (alphabetized),
5375 then the . include files in double-quotes (alphabetized). Fix
5376 dependency breakages encountered in this process, as follows:
5377 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5378 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5379 * src/state.h: Include "symtab.h".
5381 2002-12-08 Paul Eggert <eggert@twinsun.com>
5383 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5384 since this causes problems when __file__ contains character
5385 sequences like "@" that are treated specially by src/scan-skel.l.
5386 Instead, just use the file's basename. This fixes the bug
5387 reported by Martin Mokrejs in
5388 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5390 2002-12-06 Paul Eggert <eggert@twinsun.com>
5392 Add support for rules that do not have trailing semicolons, as
5393 POSIX requires. Improve the quality of locations in Bison
5394 diagnostics.
5396 * src/location.c: Include <quotearg.h>.
5397 (empty_location): Now const.
5398 (location_print): New function. Follow the recommendation of the
5399 GNU Coding Standards for locations that span file boundaries.
5400 * src/location.h: Do not include <quotearg.h>; no longer needed.
5401 (boundary): New type.
5402 (location_t): Use it. This allows locations to span file boundaries.
5403 All member uses changed: file -> start.file or end.file (as needed),
5404 first_line -> start.line, first_column -> start.column,
5405 last_line -> end.line, last_column -> end.column.
5406 (equal_boundaries): New function.
5407 (LOCATION_RESET, LOCATION_STEP): Remove.
5408 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5409 (empty_location): Now const.
5410 (location_print): New decl.
5411 * src/parse-gram.y (lloc_default): New function, which handles
5412 empty locations more accurately.
5413 (YYLLOC_DEFAULT): Use it.
5414 (%token COLON): Remove.
5415 (%token ID_COLON): New token.
5416 (rules): Use it.
5417 (declarations, rules): Remove trailing semicolon.
5418 (declaration, rules_or_grammar_declaration):
5419 Allow empty (";") declaration.
5420 (symbol_def): Remove empty actions; no longer needed.
5421 (rules_or_grammar_declaration): Remove trailing semicolon.
5422 (semi_colon.opt): Remove.
5423 * src/reader.h: Include location.h.
5424 (scanner_cursor): New decl.
5425 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
5426 rolling our own.
5427 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
5428 of *loc.
5429 (STEP): Remove. No longer needed, now that adjust_location does
5430 the work. All uses removed.
5431 (scanner_cursor): New var.
5432 (adjust_location): Renamed from extend_location. It now sets
5433 *loc and adjusts the scanner cursor. All uses changed.
5434 Don't bother testing for CR.
5435 (handle_syncline): Remove location arg; now updates scanner cursor.
5436 All callers changed.
5437 (unexpected_end_of_file): Now accepts start boundary of token or
5438 comment, not location. All callers changed. Update scanner cursor,
5439 not the location.
5440 (SC_AFTER_IDENTIFIER): New state.
5441 (context_state): Renamed from c_context. All uses changed.
5442 (id_loc, code_start, token_start): New local vars.
5443 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5444 processing of Yacc white space and equivalents here.
5445 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5446 instead of returning ID immediately, since we need to search for
5447 a subsequent colon.
5448 (<INITIAL>"'", "\""): Save token_start.
5449 (<INITIAL>"%{", "{", "%%"): Save code_start.
5450 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5451 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5452 BEGIN context_state at end, not INITIAL.
5453 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5454 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5455 Return correct token start.
5456 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5457 the start of a character, string or multiline comment is found.
5458 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5459 Reduction): Adjust reported locations to match the more-precise
5460 results now expected.
5461 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5462 * tests/reduce.at (Useless Rules, Reduced Automaton,
5463 Underivable Rules): Likewise.
5464 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5465 or "|"' now that so many other tokens are allowed by the new grammar.
5467 * src/complain.h (current_file): Remove duplicate decl;
5468 current_file is now owned by files.h.
5469 * src/complain.c, src/scan-gram.l: Include files.h.
5471 2002-12-06 Paul Eggert <eggert@twinsun.com>
5473 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
5474 promotes to int; it might be unsigned int.
5475 * data/yacc.c (yy_reduce_print): Likewise.
5477 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
5478 be #defined in the prologue, not in the Bison declarations.
5479 This fixes Debian Bug 102878, reported by Shaul Karl.
5481 2002-12-02 Paul Eggert <eggert@twinsun.com>
5483 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
5484 * lib/strtoul.c: New file, from gnulib.
5485 This fixes a porting bug reported by Peter Klein in
5486 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
5488 2002-11-30 Paul Eggert <eggert@twinsun.com>
5490 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
5491 and put only a forward declaration in the prologue. This is for
5492 consistency with the other scanner helper functions.
5494 Type clashes now generate warnings, not errors, since it
5495 appears that POSIX may allow some grammars with type clashes.
5496 * src/reader.c (grammar_current_rule_check): Warn about
5497 type clashes instead of complaining.
5498 * tests/input.at (Type Clashes): Expect warnings, not complaints.
5500 Add Yacc library, since POSIX requires it.
5501 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
5502 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
5503 * lib/main.c, lib/yyerror.c: New files.
5505 gram_error can be static; it need not be extern.
5506 * src/reader.h (gram_error): Remove decl.
5507 * src/parse-gram.y (gram_error): Now static. Add static decl.
5508 (print_token_value): Omit parameter names from forward decl,
5509 for consistency.
5511 2002-11-29 Paul Eggert <eggert@twinsun.com>
5513 * doc/bison.texinfo: Emphasize that yylex and yyerror must
5514 be declared before being used. E.g., one should typically
5515 declare them in the prologue. Use GNU coding style in examples.
5516 Put "const" consistently after the type it modifies. Mention
5517 that C99 supports "inline". Mention that yyerror traditionally
5518 returns "int".
5520 %parse-param and %lex-param now take just one argument, the
5521 declaration; the argument name is deduced from the declaration.
5523 * doc/bison.texinfo (Parser Function, Pure Calling, Error
5524 Reporting, Table of Symbols): Document this.
5525 * src/parse-gram.y (add_param): New function.
5526 (COMMA): Remove.
5527 (declaration): Implement new rule for %parse-param and %lex-param.
5528 * src/scan-gram.l: "," now elicits a warning, rather than being
5529 a token; this is more compatible with byacc.
5530 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
5532 2002-11-27 Paul Eggert <eggert@twinsun.com>
5534 Rename identifiers to avoid real and potential collisions.
5536 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
5537 to avoid collision with lex macro described by Bruce Lilly in
5538 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5539 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
5540 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
5541 * src/parse-gram.y (print_token_value): Renamed from yyprint.
5542 All uses changed.
5543 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
5544 The name "yycontrol" violates the name space rules, and this stuff
5545 wasn't being used anyway.
5546 (input): Remove action; this stuff wasn't being used.
5547 (gram_error): Rename local variable yylloc -> loc.
5548 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
5549 (YY_DECL): Don't use "yy" at start of local variables.
5550 All uses changed, e.g., yylloc -> loc.
5551 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
5552 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
5553 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
5554 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
5556 * src/parse-gram.y (gram_error): loc is now const *.
5557 * src/reader.h (gram_error): Likewise.
5559 2002-11-24 Paul Eggert <eggert@twinsun.com>
5561 Version 1.75c.
5563 * tests/actions.at (Actions after errors): Use an output format
5564 more similar to that of the Printers and Destructors test.
5565 Test the position of the ';' token too.
5566 (Printers and Destructors): Likewise.
5567 (Printers and Destructors: %glr-parser): Remove for now, to avoid
5568 unnecessarily alarming people when the test fails.
5570 * data/yacc.c (yyerrlab1): Move this label down, so that the
5571 parser does not discard the lookahead token if the user code
5572 invokes YYERROR. This change is required for POSIX conformance.
5574 * lib/error.c: Sync with gnulib.
5576 2002-11-22 Paul Eggert <eggert@twinsun.com>
5578 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
5579 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
5580 * lib/xmalloc.c: Likewise.
5582 2002-11-20 Paul Eggert <eggert@twinsun.com>
5584 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
5586 2002-11-20 Paul Eggert <eggert@twinsun.com>
5588 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
5589 should use `if (! x) abort ();' rather than `assert (x);', and
5590 anyway it's one less thing to worry about configuring.
5592 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
5593 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
5594 and replace all instances of assert with abort.
5595 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5596 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
5598 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
5599 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
5600 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
5601 hash_find_entry, hash_rehash, hash_insert): Likewise.
5602 * src/conflicts.c (resolve_sr_conflict): Likewise.
5603 * src/lalr.c (set_goto_map, map_goto): Likewise.
5604 * src/nullable.c (nullable_compute): Likewise.
5605 * src/output.c (prepare_rules, token_definitions_output): Likewise.
5606 * src/reader.c (packgram, reader): Likewise.
5607 * src/state.c (state_new, state_free, state_transitions_set,
5608 state_reduction_find): Likewise.
5609 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
5610 symbol_pack): Likewise.
5611 * src/tables.c (conflict_row, pack_vector): Likewise.
5612 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
5613 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
5614 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
5615 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
5617 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
5618 (ARGMATCH_CONSTRAINT): New macro.
5619 (ARGMATCH_ASSERT): Use it.
5621 * src/system.h (verify): New macro.
5622 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
5623 rather than assert.
5624 * src/tables.c (tables_generate): Likewise.
5626 * src/struniq.c (struniq_assert): Now returns void, and aborts
5627 if the assertion is false.
5628 (struniq_assert_p): Remove.
5629 * src/struniq.h: Likewise.
5631 2002-11-18 Paul Eggert <eggert@twinsun.com>
5633 * data/glr.c (yygetLRActions): Replace `yyindex' with
5634 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
5635 This fixes the regression with Sun ONE Studio 7 cc that I reported in
5636 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
5638 2002-11-18 Akim Demaille <akim@epita.fr>
5640 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
5641 space.
5642 From Tim Van Holder.
5644 2002-11-17 Paul Eggert <eggert@twinsun.com>
5646 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
5647 to "SyntaxError" for consistency with my 2002-11-15 change.
5649 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
5650 not define to {}, since this breaks the common use of `YYDPRINTF
5651 ((...));' if a single statement is desired (e.g. before `else').
5652 Work around GCC warnings by surrounding corresponding calls with
5653 {} if needed.
5654 (yyhasResolvedValue): Remove unused function.
5655 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
5656 loop body.
5657 (yyreportSyntaxError): Renamed from yyreportParseError.
5658 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
5659 All uses changed.
5660 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
5661 extern when possible. Remove unused initializations.
5663 2002-11-16 Akim Demaille <akim@epita.fr>
5665 Augment the similarity between GLR and LALR traces.
5667 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
5668 (YY_REDUCE_PRINT): New.
5669 (yyparse): Use them.
5670 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
5671 YYDPRINT here.
5672 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
5673 state reached after the reduction/recovery, since...
5674 (yyparse, yyprocessOneStack): Report the state we are entering in.
5676 2002-11-16 Akim Demaille <akim@epita.fr>
5678 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
5679 Add support for --trace=skeleton.
5680 * src/scan-skel.l: %option debug.
5681 Scan strings of non-@ or \n instead of character by character.
5682 (scan_skel): Handle trace_skeleton.
5683 (QPUTS): New.
5684 (@output_parser_name@, @output_header_name@): ``Restore'' their
5685 support (used to be M4 macros).
5686 * data/yacc.c: Quote larger chunks, a la glr.c.
5687 * data/lalr1.cc: Likewise.
5688 The header guards are no longer available, so use some other
5689 string than `YYLSP_NEEDED'.
5691 2002-11-16 Akim Demaille <akim@epita.fr>
5693 Make the ``Printers and Destructors'' test more verbose, taking
5694 `yacc.c''s behavior as (possibly wrong) reference.
5696 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
5697 instead of fprint on stdout.
5698 Set and report the last_line of the symbols.
5699 Consistently display values and locations.
5701 2002-11-16 Paul Eggert <eggert@twinsun.com>
5703 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
5705 2002-11-15 Paul Eggert <eggert@twinsun.com>
5707 * tests/actions.at (Actions after errors): New test case.
5709 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
5710 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
5711 tests/action.at, tests/calc.at, tests/conflicts.at,
5712 tests/cxx-type.at, tests/regression.at:
5713 "parse error" -> "syntax error" for POSIX compatibility.
5714 "parsing stack overflow..." -> "parser stack overflow" so
5715 that code matches Bison documentation.
5717 2002-11-15 Akim Demaille <akim@epita.fr>
5719 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
5720 take two BRACED_CODE, not two string_content.
5721 Free the scanner's obstack when we are done.
5722 (code_content): New.
5723 * tests/calc.at: Adjust.
5724 * doc/bison.texinfo: Adjust.
5725 Also, make sure to include the `,' for these declarations.
5727 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
5729 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
5730 definition; avoids potential autoreconf problems.
5732 2002-11-15 Akim Demaille <akim@epita.fr>
5734 Always check the value returned by yyparse.
5736 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
5737 returned by yyparse.
5738 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
5739 Adjust calls.
5740 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
5741 returned by yyparse.
5743 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5745 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
5746 on input.at test.
5748 2002-11-14 Paul Eggert <eggert@twinsun.com>
5750 * src/output.c (output_skeleton): Call xfopen instead of
5751 duplicating xfopen's body.
5753 Fix bugs reported by Nelson H. F. Beebe in
5754 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
5756 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
5757 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
5758 Group compiler. Instead, use "$CC -E bar.c". Include the .h
5759 file twice in the grammar, as an extra check.
5761 * tests/input.at (Torturing the Scanner): Surround the
5762 backslash-newline tests with "#if 0", to make it less likely that
5763 we'll run into compiler bugs. Bring back solitary \ inside
5764 comment, but add a closing comment to work around HP C bug. Don't
5765 test backslash-newline in C character constant.
5767 2002-11-14 Akim Demaille <akim@epita.fr>
5769 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
5770 status of the compiler.
5771 Calling `exit 1' is no longer needed.
5772 Reported by Nelson H. F. Beebe.
5774 2002-11-14 Akim Demaille <akim@epita.fr>
5776 * tests/atlocal.in (CPPFLAGS): We have config.h.
5777 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
5778 New.
5779 * tests/actions.at, tests/calc.at, tests/conflicts.at,
5780 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
5781 * tests/regression.at, tests/torture.at: Use them for all the
5782 grammars that are to be compiled.
5783 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
5784 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
5785 * doc/bison.texinfo (GLR Parsers): Document `inline'.
5787 2002-11-14 Akim Demaille <akim@epita.fr>
5789 * doc/bison.texinfo: Various formatting changes (alignments in
5790 samples, additional @group/@end group, GCS in samples.
5791 Use @deffn instead of simple @table to define the directives,
5792 macros, variables etc.
5794 2002-11-13 Paul Eggert <eggert@twinsun.com>
5796 Fix some bugs reported by Albert Chin-A-Young in
5797 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
5799 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
5800 -o c"; the HP C compiler chatters during compilation.
5801 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
5802 * tests/headers.at (export YYLTYPE): Likewise.
5804 * tests/input.at (Torturing the Scanner): Remove lines containing
5805 solitary backslashes, as they tickle a bug in the HP C compiler.
5807 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
5808 comments, since they're not portable. Use GNU coding style.
5810 2002-11-13 Akim Demaille <akim@epita.fr>
5812 * data/yacc.c: Leave bigger chunks of quoted text.
5813 (YYDSYMPRINTF): New.
5814 Use it to report symbol activities.
5815 * data/glr.c (YYDSYMPRINTF): New.
5816 Use it.
5818 2002-11-12 Paul Eggert <eggert@twinsun.com>
5820 Version 1.75b.
5822 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
5823 (yyglrReduce): Return yyok, not 0.
5824 This should avoid the enumerated-type warnings reported
5825 by Nelson H. F. Beebe in
5826 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
5828 * lib/bbitset.h (BITSET_INLINE): Remove.
5829 * lib/bitset.h [! BITSET_INLINE]: Remove.
5830 (bitset_set, bitset_reset, bitset_test): Rename local vars
5831 to avoid shadowing warnings by GCC.
5833 * data/glr.c (inline): Remove #define. It's the user's
5834 responsibility to #define it away, just like 'const'.
5835 This fixes one of the bugs reported by Nelson H. F. Beebe in
5836 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
5838 * Makefile.maint (po-check): Scan .l and .y files instead of the
5839 .c and the .h files that they generate. This fixes the bug
5840 reported by Tim Van Holder in:
5841 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
5842 Look for N_ as well as for _. Try to avoid matching #define for
5843 N_ and _.
5844 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
5845 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
5846 * src/scan-gram.l: Revamp regular expressions so that " and '
5847 do not confuse xgettext.
5849 * src/struniq.h (struniq_new): Do not declare the return type
5850 to be 'const'; this violates the C standard.
5851 * src/struniq.c (struniq_new): Likewise.
5853 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
5855 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
5856 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
5857 linker.

5883 2002-11-12 Akim Demaille <akim@epita.fr>
5885 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
5886 defines it.
5887 * data/glr.c (yystos): New.
5888 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
5889 (YYDSYMPRINT): New.

5891 (yyrecoverParseError): Free verbosely the discarded symbols.
5892 * data/yacc.c (yysymprint): Remove, rather...
5893 (b4_yysymprint_generate): invoke.
5894 * data/c.m4 (b4_yysymprint_generate): New.
5895 Accept pointers as arguments, as opposed to the version from
5896 yacc.c.
5897 (b4_yydestruct_generate): Likewise.
5898 * tests/cations.at (Printers and Destructors): Use Bison directives
5899 instead of CPP macros.

5904 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
5905 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
5906 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
5907 it against YYEMPTY and so forth), work on yytoken (i.e., set
5908 it to YYEMPTY etc.).
5909 (yydestruct): Replace with a b4_yydestruct_generate invocation.
5910 (b4_symbol_actions): Remove.
5911 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
5912 for 0, end-of-input.
5914 2002-11-12 Akim Demaille <akim@epita.fr>
5916 * doc/bison.texinfo (Destructor Decl): New.
5918 2002-11-12 Akim Demaille <akim@epita.fr>
5920 * src/tables.c (tables_generate): Use free for pointers that
5921 cannot be NULL, not XFREE.
5922 (pack_vector): Use assert, not fatal, for bound violations.
5923 * src/state.c (state_new): Likewise.
5924 * src/reader.c (reader): Likewise.
5925 * src/lalr.c (set_goto_map): Likewise.

5927 the file name.
5929 2002-11-12 Akim Demaille <akim@epita.fr>
5931 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
5932 Restore.
5933 * src/scan-gram.l (last_string): Is global to the file, not to
5934 yylex.
5935 * src/parse-gram.y (input): Don't append the epilogue here,
5936 (epilogue.opt): do it here, and free the scanner's obstack.
5937 * src/reader.c (epilogue_set): Rename as...
5938 (epilogue_augment): this.
5939 * data/c.m4 (b4_epilogue): Defaults to empty.

5945 Remove.
5946 * doc/bison.rnh: Remove.
5947 * doc/bison.texinfo (VMS Invocation): Remove.
5949 2002-11-12 Akim Demaille <akim@epita.fr>

5952 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
5954 Use struniq for symbols.
5956 * src/symtab.h (symbol_t): The tag member is a struniq.

5997 2002-11-11 Paul Eggert <eggert@twinsun.com>
5999 Revamp to fix many (but not all) of the C- and M4-related quoting
6000 problems. Among other things, this fixes the Bison bug reported
6001 by Jan Hubicka when processing the Bash grammar; see:
6002 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6004 Use new @ escapes consistently. Represent brackets with @{ and @}
6005 rather than @<:@ and @:>@, since this works a bit better with dumb
6006 editors like vi. Represent @ with @@, since @ is now consistently
6007 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6008 __ofile__, to avoid unexpected expansions. Similarly, use @output
6009 rather than #output.
6011 * data/c.m4 (b4_copyright): Omit file name from comment, since
6012 the file name could contain "*/".
6013 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6014 be quoted. All uses changed.
6016 * data/glr.c: Use new @ escapes consistently.
6017 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6018 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6019 Remove, since they couldn't handle arbitrary characters in file
6020 names.
6021 * data/lalr1.cc: Likewise.
6022 * data/yacc.c: Likewise.
6024 * src/files.c (output_infix): Remove; all uses removed.
6025 * src/files.h: Likewise.
6027 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6028 mishandled funny characters in file names, and anyway it isn't
6029 needed any more.
6030 * data/yacc.c: Likewise.
6031 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6033 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6034 * data/yacc.c: Likewise.
6036 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6037 strings now.
6038 (muscle_init): Quote filename as a C string.
6039 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6040 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6041 * src/output.c (escaped_file_name_output): New function.
6042 (prepare_symbols): Quote tokens for M4.
6043 (prepare): Don't insert output_infix, output_prefix,
6044 output_parser_name, output_header_name; this is now down by scan-skel.
6045 Insert skeleton as a C string.
6047 * src/output.c (user_actions_output, symbol_destructors_output,
6048 symbol_printers_output): Quote filenames for C and M4.
6049 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6051 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
6052 escapes other than \\ and \'; this simplifies the code.
6053 (<SC_STRING>): Likewise, for \\ and \".
6054 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6055 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6056 Use new escapes @{ and @} for [ and ].
6058 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6059 them with auto vars.
6060 Switch to new escape scheme, where @ is the escape character uniformly.
6061 Abort if a stray escape character is found. Avoid unbounded input
6062 buffer when parsing non-escaped text.
6064 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6065 __oline__, #output, $@, and @{ do not have unintended meanings.
6067 2002-11-09 Paul Eggert <eggert@twinsun.com>
6069 Fix the test failure due to GCC warnings described in
6070 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6071 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6072 evaluate to 0 if it's impossible for NINF to be in the respective
6073 table.
6074 (yygetLRActions, yyrecoverParseError): Use them.
6076 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6077 counted in the token inserted at end of file. Now takes
6078 location_t *, not location_t, so that the location can be
6079 adjusted. All uses changed.
6081 * tests/regression.at (Invalid inputs): Adjust wording in
6082 diagnostic to match the new behavior.
6084 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6085 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6086 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6087 abort ();'. This reduces the runtime of the "Many lookaheads"
6088 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
6089 GCC 3.2.
6091 2002-11-07 Paul Eggert <eggert@twinsun.com>
6093 * src/parse-gram.y (CHARACTER): Remove unused token.
6094 All uses removed.
6096 * src/scan-gram.l: Remove stack option. We no longer use the
6097 stack, since the stack was never deeper than 1; instead, use the
6098 new auto var c_context to record the stacked value.
6100 Remove nounput option. At an unexpected end of file, we now unput
6101 the minimal input necessary to end cleanly; this simplifies the
6102 code.
6104 Avoid unbounded token sizes where this is easy.
6106 (unexpected_end_of_file): New function.
6107 Use it to systematize the error message on unexpected EOF.
6108 (last-string): Now auto, not static.
6109 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
6110 (scanner_last_string_free): Remove; not used.
6111 (percent_percent_count): Move decl to just before use.
6112 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
6113 not the (never otherwised-used) CHARACTER.
6115 2002-11-07 Akim Demaille <akim@epita.fr>
6117 Let yyerror always receive the msg as last argument, so that
6118 yyerror can be variadic.
6120 * data/yacc.c (b4_yyerror_args): New.
6121 Use it when calling yyerror.
6122 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
6123 Use it when calling yyerror.
6124 * doc/bison.texinfo (Error Reporting): Adjust.
6125 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
6126 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
6128 2002-11-06 Akim Demaille <akim@epita.fr>
6130 #line should have quoted strings.
6131 Ideally, this should be done by m4_quotearg.
6133 * src/scan-skel.l: Include quotearg.h.
6134 Quote __ofile__.
6135 * src/output.c (symbol_printers_output)
6136 (symbol_destructors_output): Quote the file name.
6138 2002-11-06 Akim Demaille <akim@epita.fr>
6140 * tests/regression.at (Invalid inputs): Adjust to the recent
6141 messages.

6145 Restore --no-lines.
6146 Reported by Jim Kent.

6151 * src/output.c (user_actions_output): Likewise.
6152 (prepare): Define 'b4_synclines_flag'.
6153 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
6155 2002-11-06 Akim Demaille <akim@epita.fr>
6157 * src/main.c (main): Free `infile'.
6158 * src/scan-gram.l (handle_syncline): New.
6159 Recognize `#line'.
6160 * src/output.c (user_actions_output, symbol_destructors_output)
6161 (symbol_printers_output): Use the location's file name, not
6162 infile.
6163 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6165 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6167 * src/tables.c (matching_state): Don't allow states to match if
6168 either has GLR conflict entries.
6170 2002-11-05 Paul Eggert <eggert@twinsun.com>
6172 * src/scan-gram.l: Use more accurate diagnostics, e.g.
6173 "integer out of range" rather than "invalid value".
6174 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
6175 accordingly.
6177 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
6178 Also, remove one static variable in the scanner.
6180 * src/scan-gram.l (braces_level): Now auto, not static.
6181 Initialize to zero if the compiler is being picky.
6182 (INITIAL): Clear braces_level instead of incrementing it.
6183 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
6184 as POSIX 1003.1-2001 requires.
6185 * src/system.h (IF_LINT): New macro, taken from coreutils.
6186 * configure.ac: Define "lint" if --enable-gcc-warnings.
6188 2002-11-05 Akim Demaille <akim@epita.fr>
6190 * src/scan-gram.l: When it starts with `%', complain about the
6191 whole directive, not just that `invalid character: %'.
6193 2002-11-04 Akim Demaille <akim@epita.fr>
6195 * Makefile.maint: Update from Autoconf.
6196 (update, cvs-update, po-update, do-po-update): New.

6207 2002-11-04 Akim Demaille <akim@epita.fr>
6209 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
6210 clashes.
6211 * src/scan-gram.l: Use [\'] instead of ['] to pacify
6212 font-lock-mode.
6213 Use complain_at.
6214 Use quote, not quote_n since LOCATION_PRINT no longer uses the
6215 slot 0.
6217 2002-11-03 Paul Eggert <eggert@twinsun.com>
6219 * src/reader.c (get_merge_function, grammar_current_rule_check):
6220 Use consistent diagnostics for reporting type name clashes.
6221 Quote the types with <>, for consistency with Yacc.
6222 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
6224 2002-11-03 Akim Demaille <akim@epita.fr>

6266 2002-11-03 Paul Eggert <eggert@twinsun.com>
6268 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,

6295 ({int}, handle_action_dollar, handle_action_at): Check for integer
6296 overflow.
6298 (YY_STEP): Omit trailing semicolon, so that it's more like C.
6300 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
6301 as well as \000. Check for UCHAR_MAX, not 255.
6302 Allow \x with an arbitrary positive number of digits, as in C.
6303 Check for overflow here.
6304 Allow \? and UCNs, for compatibility with C.
6306 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
6307 with quote slot used by complain_at.
6309 * tests/input.at: Add tests for backslash-newline, m4 quotes
6310 in symbols, long literals, and funny escapes in strings.
6312 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
6313 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
6314 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
6315 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
6316 * m4/mbswidth.m4: New file, from GNU coreutils.
6318 * doc/bison.texinfo (Grammar Outline): Document // comments.
6319 (Symbols): Document that trigraphs have no special meaning in Bison,
6320 nor is backslash-newline allowed.
6321 (Actions): Document that trigraphs have no special meaning.
6323 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
6324 no longer used.
6326 2002-11-02 Paul Eggert <eggert@twinsun.com>
6328 * src/reader.c: Don't include quote.h; not needed.
6329 (get_merge_function): Reword warning to be consistent with
6330 type clash diagnostic in grammar_current_rule_check.
6332 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
6333 bug in trigraph handling.
6335 * src/output.c (prepare_symbols): When printing token names,
6336 escape "[" as "@<:@" and likewise for "]".
6338 * src/system.h (errno): Remove declaration, as we are now
6339 assuming C89 or better, and C89 guarantees errno.
6341 2002-10-30 Paul Eggert <eggert@twinsun.com>
6343 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
6344 Check for close failures.
6345 * src/files.h (xfclose): Return void, not int, since it always
6346 returned zero.
6347 * src/files.c (xfclose): Likewise. Report I/O error if ferror
6348 indicates one.
6349 * src/output.c (output_skeleton): Use xfclose rather than fclose
6350 and ferror. xfclose now checks ferror.
6352 * data/glr.c (YYLEFTMOST_STATE): Remove.
6353 (yyreportTree): Use a stack-based leftmost state. This avoids
6354 our continuing battles with bogus warnings about initializers.
6356 2002-10-30 Akim Demaille <akim@epita.fr>
6358 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
6359 #if.
6361 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6363 * tests/glr-regr1.at: New test for reported regressions.
6364 * tests/testsuite.at: Add glr-regr1.at test.
6365 * tests/Makefile.am: Add glr-regr1.at test.
6367 2002-10-24 Paul Eggert <eggert@twinsun.com>
6369 Version 1.75a.
6371 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6372 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6373 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6374 Don't assume strdup exists; POSIX says its an XSI extension.
6375 Check for buffer overflow on input.
6377 2002-10-24 Akim Demaille <akim@epita.fr>
6379 * src/output.c (output_skeleton): Don't disable M4sugar comments
6380 too soon: it results in comments being expanded.
6381 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6382 first output.
6384 2002-10-24 Akim Demaille <akim@epita.fr>
6386 * data/yacc.c (m4_int_type): New.
6387 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6388 char' as only yacc.c wants K&R portability.
6389 * data/glr.c (yysigned_char): Remove.
6390 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
6391 Reported by Quoc Peyrot.
6393 2002-10-23 Paul Eggert <eggert@twinsun.com>
6395 * src/main.c (main): With --trace=time, report times even if a
6396 non-fatal error occurs. Formerly, the times were reported in some
6397 such cases but not in others.
6398 * src/reader.c (reader): Just return if a complaint has been issued,
6399 instead of exiting, so that 'main' can report times.
6401 2002-10-22 Akim Demaille <akim@epita.fr>
6403 * src/system.h: Include sys/types.
6404 Reported by Bert Deknuydt.
6406 2002-10-23 Paul Eggert <eggert@twinsun.com>
6408 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
6409 Suggested by Art Haas.
6411 2002-10-22 Paul Eggert <eggert@twinsun.com>
6413 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6414 decl; not needed any more.
6415 * src/main.c (main): Use return to exit, undoing yesterday's change.
6416 The last OS that we could find where this wouldn't work is
6417 SunOS 3.5, and that's too old to worry about now.
6419 * data/glr.c (struct yyltype): Define members even when not
6420 doing locations. This is more consistent with yacc.c, and it
6421 works around the following bug reports:
6422 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6423 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6425 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6426 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6427 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6429 2002-10-22 Akim Demaille <akim@epita.fr>
6431 * data/README: New.
6433 2002-10-21 Paul Eggert <eggert@twinsun.com>
6435 Be consistent about 'bool'; the old code used an enum in one
6436 module and an int in another, and this violates the C standard.
6437 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6438 * configure.ac (AC_HEADER_STDBOOL): Add.
6439 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
6440 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
6441 * src/symtab.c (hash_compare_symbol_t): Likewise.
6442 * src/system.h (bool, false, true): Use a definition consistent
6443 with ../lib/hash.c. All uses changed.
6445 * src/complain.c (warning_issued): Renamed from warn_message_count,
6446 so that we needn't worry about integer overflow (!).
6447 Now of type bool. All uses changed.
6448 (complaint_issued): Renamed from complain_message_count; likewise.
6450 * src/main.c (main): Use exit to exit with failure.
6452 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6453 rather than 1 and 0.
6454 * src/main.c (main): Likewise.
6455 * src/getargs.c (getargs): Likewise.
6456 * src/reader.c (reader): Likewise.
6458 * src/getarg.c (getargs): Remove duplicate code for
6459 "Try `bison --help'".
6461 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6462 What was that "2" for?
6464 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6465 * src/getargs.c (usage): Likewise.
6467 * src/getargs.c (getargs): When there are too few operands, report
6468 the last one. When there are too many, report the first extra
6469 one. This is how diffutils does it.
6471 2002-10-20 Paul Eggert <eggert@twinsun.com>
6473 Remove K&R vestiges.
6474 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
6475 * src/complain.c (VA_START): Remove. Assume prototypes.
6476 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
6477 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
6478 fatal): Assume prototypes.
6479 * src/complain.h: Assume prototypes.
6480 * src/system.h (PARAMS): Remove.
6481 Include <limits.h> unconditionally, since it's guaranteeed even
6482 for a freestanding C89 compiler.
6483 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
6484 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
6486 2002-10-20 Akim Demaille <akim@epita.fr>
6488 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
6489 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
6490 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
6491 (yyresolveStates, yyresolveAction, yyresolveStack)
6492 (yyprocessOneStack): Use them.
6493 (yy_reduce_print): New.
6494 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
6496 2002-10-20 Akim Demaille <akim@epita.fr>
6498 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
6499 arguments and output `void'.
6500 (b4_c_function): Rename as...
6501 (b4_c_function_def): this.
6502 (b4_c_function_decl, b4_c_ansi_function_def)
6503 (b4_c_ansi_function_decl): New.
6504 Change the interpretation of the arguments: before `int, foo', now
6505 `int foo, foo'.
6506 * data/yacc.c (yyparse): Prototype and define thanks to these.
6507 Adjust b4_c_function_def uses.
6508 * data/glr.c (yyparse): Likewise, but ANSI only.
6510 2002-10-20 Akim Demaille <akim@epita.fr>
6512 * src/output.c (prepare): Move the definition of `tokens_number',
6513 `nterms_number', `undef_token_number', `user_token_number_max'
6514 to...
6515 (prepare_tokens): Here.
6516 (prepare_tokens): Rename as...
6517 (prepare_symbols): this.
6518 (prepare): Move the definition of `rules_number' to...
6519 (prepare_rules): here.
6520 (prepare): Move the definition of `last', `final_state_number',
6521 `states_number' to...
6522 (prepare_states): here.
6523 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
6525 2002-10-20 Akim Demaille <akim@epita.fr>
6527 * src/tables.h, src/tables.c, src/output.c: Comment changes.
6529 2002-10-20 Akim Demaille <akim@epita.fr>
6531 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
6532 * data/c.m4: here.
6534 2002-10-20 Akim Demaille <akim@epita.fr>
6536 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
6537 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
6538 `pair'.
6539 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
6540 `name' to...
6541 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
6542 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
6543 These.
6545 2002-10-19 Paul Eggert <eggert@twinsun.com>
6547 Do not create a temporary file, as that involves security and
6548 cleanup headaches. Instead, use a pair of pipes.
6549 Derived from a suggestion by Florian Krohm.
6550 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
6551 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
6552 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
6553 (BISON_PREREQ_SUBPIPE): Add.
6554 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
6555 Add subpipe.h, subpipe.c.
6556 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
6557 * po/POTFILES.in: Add lib/subpipe.c.
6558 * src/output.c: Include "subpipe.h".
6559 (m4_invoke): Remove decl.
6560 (scan_skel): New decl.
6561 (output_skeleton): Use pipe rather than temporary file for m4 input.
6562 Check that m4sugar.m4 is readable, to avoid deadlock.
6563 Check for pipe I/O error.
6564 * src/scan-skel.l (readpipe): Remove decl.
6565 (scan_skel): New function, to be used in place of m4_invoke.
6566 Read from stream rather than file.
6568 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
6569 float, as this generates a warning on Solaris 8 + GCC 3.2 with
6570 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
6571 this generates a more-accurate value anyway.
6573 * lib/timevar.c (timervar_accumulate): Rename locals to
6574 avoid confusion with similarly-named more-global.
6575 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
6577 * src/output.c (prepare): Use xstrdup to convert char const *
6578 to char *, to avoid GCC warning.
6580 2002-10-19 Akim Demaille <akim@epita.fr>
6582 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
6583 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
6584 Use them to have `calc.y' ready for %pure-parser.
6585 * data/yacc.c (YYLEX): Pass a yylex return type to
6586 b4_c_function_call.
6588 2002-10-19 Akim Demaille <akim@epita.fr>
6590 Prototype support of %lex-param and %parse-param.
6592 * src/parse-gram.y: Add the definition of the %lex-param and
6593 %parse-param tokens, plus their rules.
6594 Drop the `_' version of %glr-parser.
6595 Add the "," token.
6596 * src/scan-gram.l (INITIAL): Scan them.
6597 * src/muscle_tab.c: Comment changes.
6598 (muscle_insert, muscle_find): Rename `pair' as `probe'.
6599 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
6600 (muscle_entry_s): The `value' member is no longer const.
6601 Adjust all dependencies.
6602 * src/muscle_tab.c (muscle_init): Adjust: use
6603 MUSCLE_INSERT_STRING.
6604 Initialize the obstack earlier.
6605 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
6606 (muscle_pair_list_grow): New.
6607 * data/c.m4 (b4_c_function_call, b4_c_args): New.
6608 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
6609 * tests/calc.at: Use %locations, not --locations.
6610 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
6612 2002-10-19 Akim Demaille <akim@epita.fr>
6614 * src/getargs.c (usage): Take status as argument and exit
6615 accordingly.
6616 Report the traditional `Try ... --help' message when status != 0.
6617 (usage, version): Don't take a FILE * as arg, it is pointless.
6618 (getargs): When there is an incorrect number of arguments, make it
6619 an error, and report it GNUlically thanks to `usage ()'.
6621 2002-10-18 Paul Eggert <eggert@twinsun.com>
6623 * data/glr.c (yyreportParseError): Don't assume that sprintf
6624 yields the length of the printed string, as this is not true
6625 on SunOS 4.1.4. Reported by Peter Klein.
6627 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
6628 * tests/conflicts.at (%nonassoc and eof): Likewise.
6629 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
6631 2002-10-17 Akim Demaille <akim@epita.fr>
6633 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
6634 * src/getargs.c (trace_types, trace_args): Adjust.
6635 * src/reader.c (grammar_current_rule_prec_set)
6636 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
6637 Standardize error messages.
6638 And s/@prec/%prec/!
6639 (reader): Use trace_flag to enable scanner/parser debugging,
6640 instead of an adhoc scheme.
6641 * src/scan-gram.l: Remove trailing debugging code.
6643 2002-10-16 Paul Eggert <eggert@twinsun.com>
6645 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
6646 MUSCLE_TAB_H.
6648 * NEWS: Officially drop support for building Bison with K&R C,
6649 since it didn't work anyway and it's not worth worrying about.
6650 * Makefile.maint (wget_files): Remove ansi2knr.c.
6651 (ansi2knr.c-url_prefix): Remove.
6652 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
6653 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
6654 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
6656 2002-10-15 Paul Eggert <eggert@twinsun.com>
6658 Stop using the "enum_" trick for K&R-style function definitions;
6659 it confused me, and I was the author! Instead, assume that people
6660 who want to use K&R C compilers (when using these modules in GCC,
6661 perhaps?) will run ansi2knr.
6663 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
6664 All uses of "enum_" changed to "enum ".
6665 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
6666 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
6668 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

6675 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
6676 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
6677 Use function prototypes; this removes the need for declaring
6678 static functions simply to provide their prototypes.
6679 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

6734 Version 1.75.
6736 2002-10-14 Akim Demaille <akim@epita.fr>
6738 * tests/Makefile.am (maintainer-check-posix): New.
6740 2002-10-14 Akim Demaille <akim@epita.fr>
6742 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
6743 member.
6745 2002-10-14 Akim Demaille <akim@epita.fr>
6747 * src/tables.c (table_ninf_remap): base -> tab.
6748 Reported by Matt Rosing.
6750 2002-10-14 Paul Eggert <eggert@twinsun.com>
6752 * tests/action.at, tests/calc.at, tests/conflicts.at,
6753 tests/cxx-type.at, tests/headers.at, tests/input.at,
6754 tests/regression.at, tests/synclines.at, tests/torture.at:
6755 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
6756 so that the tests still work even if POSIXLY_CORRECT is set.
6757 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
6759 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
6760 for portability to K&R hosts. Fix typo: signed char is guaranteed
6761 only to 127, not to 128.
6762 * data/glr.c (yysigned_char): New type.
6763 * data/yacc.c (yysigned_char): Likewise.
6764 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
6766 2002-10-13 Paul Eggert <eggert@twinsun.com>
6768 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
6769 true due to limited range of data type" warning from GCC.
6771 * data/c.m4 (b4_token_defines): Protect against double-inclusion
6772 by wrapping enum yytokentype's definition inside #ifndef
6773 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
6775 2002-10-13 Akim Demaille <akim@epita.fr>
6777 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
6778 Un yy- yyrhs to avoid the name clash with the global YYRHS.
6780 2002-10-13 Akim Demaille <akim@epita.fr>
6782 * Makefile.maint: Update from Autoconf 2.54.
6783 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
6785 2002-10-13 Akim Demaille <akim@epita.fr>
6787 * src/print.c (print_state): Separate the list of solved conflicts
6788 from the other items.
6789 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
6791 2002-10-13 Akim Demaille <akim@epita.fr>
6793 Let nondeterministic skeletons be usable with deterministic
6794 tables.
6796 With the patch, GAWK compiled by GCC without -O2 passes its test
6797 suite using a GLR parser driven by LALR tables. It fails with -O2
6798 because `struct stat' gives two different answers on my machine:
6799 88 (definition of an auto var) and later 96 (memset on this var).
6800 Hence the stack is badly corrumpted. The headers inclusion is to
6801 blame: if I move the awk.h inclusion before GLR's system header
6802 inclusion, the two struct stat have the same size.
6804 * src/tables.c (pack_table): Always create conflict_table.
6805 (token_actions): Always create conflict_list.
6806 * data/glr.c (YYFLAG): Remove, unused.
6808 2002-10-13 Akim Demaille <akim@epita.fr>
6810 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
6811 (O0FLAGS): New.
6812 (VALGRIND, GXX): New.
6813 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
6814 * tests/bison.in: Run $PREBISON a pre-command.
6815 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
6816 (maintainer-check-g++): New.
6817 * Makefile.am (maintainer-check): New.
6819 2002-10-13 Akim Demaille <akim@epita.fr>
6821 * data/glr.c: Formatting changes.
6822 Tweak some trace messages to match yacc.c's.
6824 2002-10-13 Akim Demaille <akim@epita.fr>
6826 GLR parsers sometimes raise parse errors instead of performing the
6827 default reduction.
6828 Reported by Charles-Henry de Boysson.
6830 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
6831 check the length of the traces when %glr.
6832 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
6833 GLR's traces.
6834 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
6835 Test GLR parsers.
6836 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
6837 (yyltype): Remove the yy prefix from the member names.
6838 (yytable): Complete its comment.
6839 (yygetLRActions): Map error action number from YYTABLE from
6840 YYTABLE_NINF to 0.
6841 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
6842 (which was a bug: it should have been YYTABEL_NINF, and yet it was
6843 not satisfying as we could compare an YYACTION computed from
6844 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
6845 only value for error actions.
6846 (yyreportParseError): In verbose parse error messages, don't issue
6847 `error' in the list of expected tokens.
6848 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
6849 next action to perform to match glr.c's decoding.
6850 (yytable): Complete its comment.
6852 2002-10-13 Paul Eggert <eggert@twinsun.com>
6854 Fix problem reported by Henrik Grubbstroem in
6855 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
6856 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
6857 because the Bison parser reads the second action before reducing
6858 the first one.
6859 * src/scan-gram.l (rule_length): New static var.
6860 Use it to keep track of the rule length in the scanner, since
6861 we can't expect the parser to be in lock-step sync with the scanner.
6862 (handle_action_dollar, handle_action_at): Use this var.
6863 * tests/actions.at (Exotic Dollars): Test for the problem.
6865 2002-10-12 Paul Eggert <eggert@twinsun.com>
6867 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
6868 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
6869 Include <sys/time.h> when checking for clock_t and struct tms.
6870 Use same include order as source.
6871 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
6872 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
6874 * lib/timevar.c: Update copyright date and clarify comments.
6875 (get_time) [IN_GCC]: Keep the GCC version for reference.
6877 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
6878 GCC version as of today, then merge Bison's changes.
6879 Change "GCC" to "Bison" in copyright notice. timevar.def's
6880 author is Akim, so change that too.
6882 * src/reader.c (grammar_current_rule_check):
6883 Don't worry about the default action if $$ is untyped.
6884 Prevents bogus warnings reported by Jim Gifford in
6885 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
6887 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
6888 * data/glr.c, data/lalr1.cc, data/yacc.c:
6889 Output token definitions before the first part of user declarations.
6890 Fixes compatibility problem reported by Jim Gifford for kbd in
6891 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
6893 2002-10-11 Paul Eggert <eggert@twinsun.com>
6895 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
6896 (yyparse): here. This undoes some of the 2002-07-25 change.
6897 Compatibility problem reported by Ralf S. Engelschall with
6898 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
6900 2002-10-11 Akim Demaille <akim@epita.fr>
6902 * tests/regression.at Characters Escapes): New.
6903 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
6904 characters.
6905 Reported by Jan Nieuwenhuizen.
6907 2002-10-11 Akim Demaille <akim@epita.fr>
6909 * po/id.po: New.
6911 2002-10-10 Paul Eggert <eggert@twinsun.com>
6913 Portability fixes for bitsets; this also avoids several GCC
6914 warnings.
6916 * lib/abitset.c: Include <stddef.h>, for offsetof.
6917 * lib/lbitset.c: Likewise.
6919 * lib/abitset.c (abitset_bytes): Return a size that is aligned
6920 properly for vectors of objects. Do not assume that adding a
6921 header size to a multiple of a word size yields a value that is
6922 properly aligned for the whole union.
6923 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6925 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
6926 unique names for structures.
6927 * lib/ebitset.c (ebitset_bytes): Likewise.
6928 * lib/lbitset.c (lbitset_bytes): Likewise.
6930 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

6935 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
6936 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
6937 to improve the type-checking that GCC can do.
6938 * lib/bitset.c (bitset_op4_cmp): Likewise.
6939 * lib/bitset_stats.c (bitset_stats_count,
6940 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

6947 bitset_stats_andn_or_cmp, bitset_stats_or_and,
6948 bitset_stats_or_and_cmp): Likewise.
6949 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
6950 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
6951 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
6952 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
6954 * lib/abitset.h: Include bitset.h, not bbitset.h.
6955 * lib/ebitset.h: Likewise.
6956 * lib/lbitset.h: Likewise.
6958 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
6959 All instances of parameters of type enum bitset_opts are now of
6960 type enum_bitset_opts, to conform to the C Standard, and similarly
6961 for enum_bitset_type.
6962 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
6963 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
6965 Do not use "struct bitset_struct" to mean different things in
6966 different modules. Not only is this confusing, it violates
6967 the C Standard, which requires that structure types in different
6968 modules must be compatible if one is to be passed to the other.
6969 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
6970 All instances of "struct bitset_struct *" replaced with "bitset".
6971 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
6972 (union bitset_union, struct abitset_struct, struct ebitset_struct,
6973 struct lbitset_struct, struct bitset_stats_struct): New types.
6974 All uses of struct bitset_struct changed to union bitset_union,
6975 etc.
6976 * lib/abitset.c (struct abitset_struct, abitset,
6977 struct bitset_struct): Remove.
6978 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
6979 struct bitset_struct): Remove.
6980 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
6981 bitset_struct): Remove.
6982 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
6983 Likewise.
6985 Do not call a function of type T using a call that assumes the
6986 function is of a different type U. Standard C requires that a
6987 function must be called with a type that is compatible with its
6988 definition.
6989 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
6990 New decls.
6991 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
6992 New functions.
6993 * lib/ebitset.c (PFV): Remove.
6994 * lib/lbitset.c (PFV): Likewise.
6995 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
6996 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
6997 decls.

6999 (ebitset_vtable): Use them.
7000 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
7001 lbitset_xor): New functions.
7002 (lbitset_vtable): Use them.
7004 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
7005 Declare.
7007 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
7008 GCC warning.
7009 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
7010 Use offsetof, for simplicity.
7012 2002-10-06 Paul Eggert <eggert@twinsun.com>
7014 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
7015 the same width as int. This reapplies a hunk of the 2002-08-12 patch
7016 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
7017 which was inadvertently undone by the 2002-09-30 patch.
7018 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
7019 the same width as int.
7021 2002-10-04 Paul Eggert <eggert@twinsun.com>
7023 Version 1.50.
7025 * configure.ac (AC_INIT), NEWS: Increment version number.
7027 * doc/bison.texinfo: Minor spelling, grammar, and white space
7028 fixes.
7029 (Symbols): Mention that any negative value returned from yylex
7030 signifies end-of-input. Warn about negative chars. Mention
7031 the portable Standard C character set.
7033 The GNU coding standard says CFLAGS and YFLAGS are reserved
7034 for the installer to set.
7035 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
7036 * src/Makefile.am (AM_CFLAGS): Likewise.
7037 (AM_YFLAGS): Renamed from YFLAGS.
7039 Fix some MAX and MIN problems.
7040 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
7041 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
7042 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
7043 * src/reader.c (reader): Use it.
7045 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
7046 POSIX 1003.1-2001 has removed fgrep.
7048 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
7050 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
7051 interpreted as signed.

7054 2002-10-01 Paul Eggert <eggert@twinsun.com>

7058 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
7059 abitset_size, abitset_list, abitset_list_reverse, abitset_list):

7099 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
7100 abitset_or_and, abitset_or_and_cmp):
7101 Use bitset_windex instead of unsigned int.
7102 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
7103 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
7104 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,

7106 Likewise.
7107 * lib/lbitset.c (lbitset_ones, lbitset_not): Likewise.
7109 * lib/bitset.c (bitset_print):
7110 Use proper printf formats for widths of integer types.

7118 BITSET_SIZE_MAX): New macros.
7119 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
7120 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
7121 to BITSET_WINDEX_MAX.
7123 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
7124 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
7125 since we now return the bitset_bindex type (not int).

7221 with an Autoconf-2.5x style configure.ac.
7223 2002-09-06 Paul Eggert <eggert@twinsun.com>
7225 * doc/bison.texinfo (Conditions): Make explicit that the GPL
7226 exception applies only to yacc.c. This is a modification of a
7227 patch originally suggested by Akim Demaille.
7229 2002-09-06 Akim Demaille <akim@epita.fr>
7231 * data/c.m4 (b4_copyright): Move the GPL exception comment from
7232 here to...

7237 (b4_ltype): Default to yy::Location from location.hh.
7239 2002-09-04 Jim Meyering <jim@meyering.net>
7241 * data/yacc.c: Guard the declaration of yytoknum also with
7242 `#ifdef YYPRINT', so it is declared only when used.

7260 * Makefile.am (SUBDIRS): Remove intl.
7261 (DISTCLEANFILES): Remove.

7274 (yyreportParseError): Use size_t for yysize.
7275 (yy_yypstack): No longer nested inside yypstates, as nested
7276 functions are not portable. Do not assume size_t is the
7277 same width as int.
7278 (yypstates): Do not assume that ptrdiff_t is the same width
7279 as int, and similarly for yyposn and YYINDEX.
7281 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

7314 * lib/error.c, lib/getopt.c, lib/getopt.h, lib/getopt1.c,
7315 lib/gettext.h: Sync with diffutils.
7317 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
7318 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
7320 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
7321 PROTOTYPES to check for prototypes, and "defined __STDC__" to
7322 check for void *.
7324 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
7325 size_t; the old version tried to do this but casted improperly.
7326 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
7327 (bitset_test): Now returns int, not unsigned long.
7329 * lib/bitset_stats.c: Include "gettext.h".
7330 (_): New macro.
7331 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
7332 name locals "index", as it generates unnecessary warnings on some
7333 hosts that have an "index" function.

7336 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

7357 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
7358 lib/timevar.c.
7359 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
7360 manual recommends.
7361 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
7363 * src/complain.c (strerror_r): Remove decl; not needed.
7364 (strerror): Use same pattern as ../lib/error.c.

7368 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
7370 * src/main.c (main): Cast result of bindtextdomain and textdomain
7371 to void, to avoid a GCC warning when --disable-nls is in effect.
7373 * src/scan-gram.l: Use strings rather than escapes when possible,
7374 to minimize the number of warnings from xgettext.
7375 (handle_action_dollar, handle_action_at): Don't use isdigit,
7376 as it mishandles negative chars and it may not work as expected
7377 outside the C locale.
7379 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
7380 this is a GCC extension and is not portable to other compilers.
7382 * src/system.h (alloca): Use same pattern as ../lib/error.c.
7383 Do not include <ctype.h>; no longer needed.
7384 Do not include <malloc.h>; no longer needed (and generates
7385 warnings on OpenBSD 3.0).
7387 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
7388 it's not portable.
7390 * tests/regression.at: Do not use 'cc -c input.c -o input';
7391 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
7393 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
7394 exit status as failure, not just exit status 1. Sun C exits
7395 with status 2 sometimes.
7397 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
7398 Use it for the two large tests.
7400 2002-08-02 Akim Demaille <akim@epita.fr>
7402 * src/conflicts.c (conflicts_output): Don't output rules never
7403 reduced here, since anyway that computation doesn't work.
7404 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
7405 (rule_useless_p, rule_never_reduced_p): New.

7411 reduced to...
7412 (token_actions): here.
7413 * src/main.c (main): Make the parser before making the report, so
7414 that rules never reduced are computed.
7415 Call grammar_rules_never_reduced_report.
7416 * src/print.c (print_results): Report rules never reduced.
7417 * tests/conflicts.at, tests/reduce.at: Adjust.
7419 2002-08-01 Akim Demaille <akim@epita.fr>
7421 Instead of attaching lookaheads and duplicating the rules being
7422 reduced by a state, attach the lookaheads to the reductions.
7424 * src/state.h (state_t): Remove the `lookaheads',
7425 `lookaheads_rule' member.
7426 (reductions_t): Add a `lookaheads' member.
7427 Use a regular array for the `rules'.

7429 to 0.
7430 (state_rule_lookaheads_print): Adjust.
7431 * src/state.h, src/state.c (state_reductions_find): New.

7438 (initialize_LA): this.
7439 (lalr_free): Adjust.
7440 * src/main.c (main): Don't free nullable and derives too early: it
7441 is used by --verbose.
7442 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
7444 2002-08-01 Akim Demaille <akim@epita.fr>
7446 * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
7447 `rule_number_t**'.
7448 (set_derives, free_derives): Rename as...
7449 (derives_compute, derives_free): this.
7450 Adjust all dependencies.
7451 * src/nullable.c (set_nullable, free_nullable): Rename as...
7452 (nullable_compute, nullable_free): these.
7453 (rule_list_t): Store rule_t *, not rule_number_t.
7454 * src/state.c (state_rule_lookaheads_print): Directly compare rule
7455 pointers, instead of their numbers.
7456 * src/main.c (main): Call nullable_free, and derives_free earlier,
7457 as they were lo longer used.
7459 2002-08-01 Akim Demaille <akim@epita.fr>
7461 * lib/timevar.c (get_time): Include children time.
7462 * src/lalr.h (LA, LArule): Don't export them: used with the
7463 state_t.
7464 * src/lalr.c (LA, LArule): Static.
7465 * src/lalr.h, src/lalr.c (lalr_free): New.
7466 * src/main.c (main): Call it.

7468 table_size, not >.
7469 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
7470 (tables_generate): do it, since that's also it which allocates
7471 them.
7472 Don't free LA and LArule, main does.
7474 2002-07-31 Akim Demaille <akim@epita.fr>
7476 Separate parser tables computation and output.

7479 (conflict_list, conflict_list_cnt, table, check, table_ninf)
7480 (yydefgoto, yydefact, high): Move to...
7481 * src/tables.h, src/tables.c: here.

7500 2002-07-31 Akim Demaille <akim@epita.fr>
7502 Steal GCC's --time-report support.
7504 * lib/timevar.c, lib/timevar.h, lib/timevar.def: New,

7511 --trace=time.
7512 * src/main.c (stage): Remove.
7513 (main): Replace `stage' invocations with timevar calls.
7514 * src/output.c: Insert pertinent timevar calls.
7516 2002-07-31 Akim Demaille <akim@epita.fr>
7518 Let --trace have arguments.
7520 * src/getargs.h (enum trace_e): New.
7521 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
7522 (long_options, short_options): --trace/-T takes an optional
7523 argument.
7524 Change all the uses of trace_flag to reflect the new flags.
7525 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
7527 Strengthen `stage' portability.
7529 * m4/stage.m4 (BISON_PREREQ_STAGE): New.

7534 times and struct tms are available.
7536 2002-07-30 Akim Demaille <akim@epita.fr>

7539 expected token.
7540 * tests/actions.at (Printers and Destructors): Adjust.
7541 * tests/calc.at (Calculator $1): Adjust.
7542 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
7543 error message, do not report the parser accepts the error token in
7544 that state.
7546 2002-07-30 Akim Demaille <akim@epita.fr>
7548 Normalize conflict related messages.
7550 * src/complain.h, src/complain.c (warn, complain): New.

7556 2002-07-30 Akim Demaille <akim@epita.fr>
7558 Report rules which are never reduced by the parser: those hidden
7559 by conflicts.
7561 * src/LR0.c (save_reductions): Don't make the final state too
7562 different: save its reduction (accept) instead of having a state
7563 without any action (no shift or goto, no reduce).
7564 Note: the final state is now a ``regular'' state, i.e., the
7565 parsers now contain `reduce 0' as default reduction.
7566 Nevertheless, since they decide to `accept' when yystate =
7567 final_state, they still will not reduce rule 0.
7568 * src/print.c (print_actions, print_reduction): Adjust.
7569 * src/output.c (action_row): Track reduced rules.
7570 (token_actions): Report rules never reduced.

7584 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not
7585 state_number_t.
7586 (errs_t): symbol_t*, not symbol_number_t.
7587 (reductions_t): rule_t*, not rule_number_t.
7588 (FOR_EACH_SHIFT): New.

7592 2002-07-29 Akim Demaille <akim@epita.fr>

7596 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
7597 (endtoken, accept): these.
7598 * src/reader.c (reader): Set endtoken's default tag to "$end".
7599 Set undeftoken's tag to "$undefined" instead of "$undefined.".

8692 (AT_DATA_HORIZONTAL_GRAMMAR): Respect the `%token ID NUM STRING'

8752 * src/reader.c (grammar_end, grammar_symbol_append): New.
8753 (readgram): Use them.
8754 Make the use of `p' as local as possible.
8756 2002-06-10 Akim Demaille <akim@epita.fr>
8758 GCJ's parser requires the tokens to be defined before the prologue.

8785 Remove `%thong' support as it is undocumented, unused, duplicates
8786 `%token's job, and creates useless e-mail traffic with people who
8787 want to know what it is, why it is undocumented, unused, and
8788 duplicates `%token's job.
8790 * src/reader.c (parse_thong_decl): Remove.
8791 * src/options.c (option_table): Remove "thong".

8866 * src/conflicts.c (log_resolution): Correct typo:

9163 values of $$, $n and so forth, output invocation to b4_lhs_value,
9164 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
9165 Note: this patch partially drops `semantic-parser' support: it
9166 always does `rule_length - n', where semantic parsers ought to
9167 always use `-n'.
9168 * data/bison.simple, data/bison.c++ (b4_lhs_value)
9169 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

9274 * src/reader.c (token_translations_init): 256 is now the default
9275 value for the error token, i.e., it will be assigned another

9279 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
9280 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
9281 etc. instead of 10, 20, 30 (which was used to `jump' over error
9282 (256) and undefined (2)).
9284 2002-04-22 Akim Demaille <akim@epita.fr>
9286 Propagate more token_number_t.

9321 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
9322 full stderr, and strip it according to the bison options, instead
9323 of composing the error message from different bits.
9324 This makes it easier to check for several error messages.
9325 Adjust all the invocations.
9326 Add an invocation exercising the error token.
9327 Add an invocation demonstrating a stupid error message.
9328 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

9335 errtoken->number.
9336 * src/reader.c (reader): Don't specify the user token number (2)
9337 for $undefined, as it uselessly prevents using it.
9338 * src/gram.h (token_number_t): Move to...
9339 * src/symtab.h: here.
9340 (state_t.number): Is a token_number_t.
9341 * src/print.c, src/reader.c: Use undeftoken->number instead of
9342 hard coded 2.
9343 (Even though this 2 is not the same as above: the number of the
9344 undeftoken remains being 2, it is its user token number which
9345 might not be 2).
9346 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
9347 `user_token_number_max'.
9348 Output `undef_token_number'.
9349 * data/bison.simple, data/bison.c++: Use them.

9370 RITEM. Note that it must be able to code symbol numbers as
9371 positive number, and the negation of rule numbers as negative
9372 numbers.
9373 Adjust all dependencies (pretty many).
9374 * src/reduce.c (rule): Remove this `short *' pointer: use
9375 item_number_t.
9376 * src/system.h (MINSHORT, MAXSHORT): Remove.
9377 Include `limits.h'.

9389 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
9390 passes, but produces negative #line number, once fixed, GCC is
9391 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
9392 C), it passes.
9393 * src/state.h (state_h): Code input lines on ints, not shorts.
9395 2002-04-08 Akim Demaille <akim@epita.fr>
9397 * src/reduce.c (reduce_grammar): First reduce the nonterminals,
9398 and then the grammar.

9410 New.
9411 Use them to define yy_token_number_type/TokenNumberType.

9535 (output_stos): Rename as...
9536 (prepare_stos): this.
9537 (output): Always invoke prepare_states, after all, just don't use it
9538 in the output if you don't need it.
9540 2002-04-07 Akim Demaille <akim@epita.fr>
9542 * src/LR0.c (new_state): Display `nstates' as the name of the
9543 newly created state.
9544 Adjust to initialize first_state and last_state if needed.
9545 Be sure to distinguish the initial from the final state.
9546 (new_states): Create the itemset of the initial state, and use
9547 new_state.
9548 * src/closure.c (closure): Now that the initial state has its
9549 items properly set, there is no need for a special case when
9550 creating `ruleset'.
9552 As a result, now the rule 0, reducing to $axiom, is visible in the
9553 outputs. Adjust the test suite.
9555 * tests/conflicts.at (Solved SR Conflicts)
9556 (Unresolved SR Conflicts): Adjust.
9557 * tests/regression.at (Web2c Report, Rule Line Numbers): Idem.
9558 * tests/conflicts.at (S/R in initial): New.
9560 2002-04-07 Akim Demaille <akim@epita.fr>

9583 * src/reader.c (packgram): Set it.
9584 * src/reduce.c (reduce_grammar_tables): Move the useless rules at
9585 the end of `rules', and count them out of `nrules'.
9586 (reduce_output, dump_grammar): Adjust.
9587 * src/print.c (print_grammar): It is no longer needed to check for
9588 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

9591 2002-04-07 Akim Demaille <akim@epita.fr>
9593 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
9594 lacking `+ 1' to nrules, Bison reported as useless a token if it
9595 was used solely to set the precedence of the last rule...
9597 2002-04-07 Akim Demaille <akim@epita.fr>
9599 * data/bison.c++, data/bison.simple: Don't output the current file
9600 name in #line, to avoid useless diffs between two identical
9601 outputs under different names.
9603 2002-04-07 Akim Demaille <akim@epita.fr>
9605 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
9606 Normalize loops to using `< nrules + 1', not `<= nrules'.
9608 2002-04-07 Akim Demaille <akim@epita.fr>
9610 * TODO: Update.
9612 2002-04-07 Akim Demaille <akim@epita.fr>

9626 * doc/bison.texinfo: Update copyright date.
9627 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

9709 2002-03-04 Robert Anisko <robert@lrde.epita.fr>
9711 * data/bison.c++: Unmerge value as yylval and value as yyval. Unmerge
9712 location as yylloc and location as yyloc. Use YYLLOC_DEFAULT, and

9891 2002-02-14 Paul Eggert <eggert@twinsun.com>
9893 Remove the support for C++ namespace cleanliness; it was
9894 causing more problems than it was curing, since it didn't work

9898 * NEWS: Document this.
9899 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
9900 of C++, as it's treated like C now.

9956 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
9957 C++ parsers.

9988 (guards_output): Check against the guard member of a rule, not the
9989 action member.
9990 Adjust callers.
9991 (output_skeleton): Don't look for the skeleton location, let m4 do
9992 that.
9993 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
9994 file will be used.
9995 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
9996 (prepare): Given that for the time being changesyntax is not
9997 usable in M4, rename the muscles using `-' to `_'.

9999 * src/output.h (actions_output, guards_output)
10000 (token_definitions_output): Adjust prototypes.

10009 shamelessly stolen from CVS Autoconf.

10029 * src/bison.simple (YYSIZE_T): Do not define merely because
10030 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
10031 On some platforms, <alloca.h> does not declare YYSTD (size_t).
10033 2002-01-27 Akim Demaille <akim@epita.fr>
10035 Fix `%nonassoc and eof'.
10037 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
10038 which were not properly copied! Replace
10039 memcpy (res->errs, src->errs, src->nerrs);
10040 with
10041 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
10042 !!!
10043 * tests/regression.at (%nonassoc and eof): Adjust to newest
10044 Autotest: `.' is not in the PATH.
10046 2002-01-27 Akim Demaille <akim@epita.fr>
10048 * tests/sets.at (AT_EXTRACT_SETS): New.
10049 (Nullable): Use it.
10050 (Firsts): New.
10052 2002-01-26 Akim Demaille <akim@epita.fr>
10054 * tests/actions.at, tests/calc.at, tests/headers.at,
10055 * tests/torture.at: Adjust to the newest Autotest which no longer
10056 forces `.' in the PATH.
10058 2002-01-25 Akim Demaille <akim@epita.fr>
10060 * tests/regression.at (%nonassoc and eof): New.
10061 Suggested by Robert Anisko.
10063 2002-01-24 Akim Demaille <akim@epita.fr>
10065 Bison dumps core when trying to complain about broken input files.
10066 Reported by Cris van Pelt.
10068 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
10069 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
10070 into...
10071 (Invalid inputs): Strengthen: exercise parse_percent_token.
10073 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
10075 * src/Makefile.am: Add bison.c++.
10076 * src/bison.c++: New skeleton.
10078 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
10080 * po/it.po: New.
10082 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
10084 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
10086 2002-01-20 Marc Autret <marc@gnu.org>
10088 * src/files.c (compute_output_file_names): Fix
10090 2002-01-20 Marc Autret <marc@gnu.org>
10092 * tests/output.at: New test.
10093 * src/files.c (compute_base_names): Don't map extensions when
10094 the YACC flag is set, use defaults.
10095 Reported by Evgeny Stambulchik.
10097 2002-01-20 Marc Autret <marc@gnu.org>
10099 * src/system.h: Need to define __attribute__ away for non-GCC
10100 compilers as well (i.e., the vendor C compiler).
10101 Suggested by Albert Chin-A-Young.
10103 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
10105 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
10106 canonical definition.
10107 * src/system.h: Use the canonical definition for PARAMS (avoids
10108 a conflict with the macro from lib/hash.h).
10110 2002-01-11 Akim Demaille <akim@epita.fr>
10112 * configure.in: Use AC_FUNC_STRNLEN.
10113 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
10115 2002-01-09 Akim Demaille <akim@epita.fr>
10117 * src/files.c, src/files.h (output_infix): New.
10118 (tab_extension): Remove.
10119 (compute_base_names): Compute the former, drop the latter.
10120 * src/output.c (prepare): Insert the muscles `output-infix', and
10121 `output-suffix'.
10122 * src/parse-skel.y (string, string.1): New.
10123 (section.header): Use it.
10124 (section.yacc): Remove.
10125 (prefix): Remove too.
10126 * src/scan-skel.l: Adjust.
10127 * src/bison.simple, src/bison.hairy: Adjust.
10129 2002-01-09 Akim Demaille <akim@epita.fr>
10131 * configure.in (WERROR_CFLAGS): Compute it.
10132 * src/Makefile.am (CFLAGS): Pass it.
10133 * tests/atlocal.in (CFLAGS): Idem.
10134 * src/files.c: Fix a few warnings.
10135 (get_extension_index): Remove, unused.
10137 2002-01-08 Akim Demaille <akim@epita.fr>
10139 * src/getargs.c (AS_FILE_NAME): New.
10140 (getargs): Use it to convert DOSish file names.
10141 * src/files.c (base_name): Rename as full_base_name to avoid
10142 clashes with `base_name ()'.
10143 (filename_split): New.
10144 (compute_base_names): N-th rewrite, using filename_split.
10146 2002-01-08 Akim Demaille <akim@epita.fr>
10148 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10149 New, stolen from the Fileutils 4.1.
10150 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10151 * configure.in: Check for the presence of memrchr, and of its
10152 prototype.
10154 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10156 * lib/hash.h (__P): Added definition for this macro.
10157 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10158 BUILT_SOURCES, to ensure they are generated first.
10159 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10160 %error-verbose to allow bootstrapping with bison 1.30x.
10162 2002-01-06 Akim Demaille <akim@epita.fr>
10164 * src/reader.c (parse_braces): Don't fetch the next char, the
10165 convention is to fetch on entry.
10166 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10167 'switch' without a following semicolon.
10168 * tests/regression.at (braces parsing): New.
10170 2002-01-06 Akim Demaille <akim@epita.fr>
10172 Bison is dead wrong in its RR conflict reports.
10174 * tests/torture.at (GNU Cim Grammar): New.
10175 * src/conflicts.c (count_rr_conflicts): Fix.
10177 2002-01-06 Akim Demaille <akim@epita.fr>
10179 Creating package.m4 from configure.ac causes too many problems.
10181 * tests/Makefile.am (package.m4): Create it by hand,
10182 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10184 2002-01-06 Akim Demaille <akim@epita.fr>
10186 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10187 skeleton.h.
10189 2002-01-04 Paul Eggert <eggert@twinsun.com>
10191 * doc/bison.texinfo (Debugging):
10192 Remove YYSTDERR; it's no longer defined or used.
10193 Also, s/cstdio.h/cstdio/.
10195 2002-01-03 Akim Demaille <akim@epita.fr>
10197 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10199 2002-01-03 Akim Demaille <akim@epita.fr>
10201 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10202 tracing code to --trace, wait for a better --trace option, with
10203 args.
10205 2002-01-03 Akim Demaille <akim@epita.fr>
10207 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10208 The ISO C++ standard is extremely clear about it: stderr is
10209 considered a macro, not a regular symbol (see table 94 `Header
10210 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10211 Therefore std:: does not apply to it. It still does with fprintf.
10212 Also, s/cstdio.h/cstdio/.
10214 2002-01-03 Akim Demaille <akim@epita.fr>
10216 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10217 for non system headers.
10219 2002-01-02 Akim Demaille <akim@epita.fr>
10221 Equip the skeleton chain with location tracking, runtime trace,
10222 pure parser and scanner.
10224 * src/parse-skel.y: Request a pure parser, locations, and prefix
10225 renaming.
10226 (%union): Having several members with the same type does not help
10227 type mismatches, simplify.
10228 (YYPRINT, yyprint): New.
10229 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10230 (skel_error): this.
10231 Handle locations.
10232 * src/scan-skel.l: Adjust to these changes.
10233 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10234 (LOCATION_PRINT, skel_control_t): New.
10236 2001-12-30 Akim Demaille <akim@epita.fr>
10238 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10239 replace `gb' with BLANKS.
10240 * src/scan-skel.l: Adjust.
10242 2001-12-30 Akim Demaille <akim@epita.fr>
10244 * src/system.h: We don't need nor want bcopy.
10245 Throw away MS-DOS crap: we don't need getpid.
10246 * configure.in: We don't need strndup. It was even causing
10247 problems: because Flex includes the headers *before* us,
10248 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10249 not visible.
10250 * lib/xstrndup.c: New.
10251 * src/scan-skel.l: Use it.
10252 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10253 * src/parse-skel.y: Use %directives instead of #defines.
10255 2001-12-30 Akim Demaille <akim@epita.fr>
10257 * src/skeleton.h: New.
10258 * src/output.c (output_parser, output_master_parser): Remove, dead
10259 code.
10260 * src/output.h (get_lines_number, actions_output, guards_output)
10261 (token_definitions_output): Prototype them.
10262 * src/parse-skel.y: Add the license notice.
10263 Include output.h and skeleton.h.
10264 (process_skeleton): Returns void, and takes a single parameter.
10265 * src/scan-skel.l: Add the license notice.
10266 Include skeleton.h.
10267 Don't use %option yylineno: it seems that then Flex imagines
10268 REJECT has been used, and therefore it won't reallocate its
10269 buffers (which makes no other sense to me than a bug). It results
10270 in warnings for `unused: yy_flex_realloc'.
10272 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10274 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10275 (MUSCLE_INSERT_PREFIX): ...to there.
10276 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10277 (MUSCLE_INSERT_PREFIX): Move from here...
10279 * src/bison.hairy: Add a section directive. Put braces around muscle
10280 names. This parser skeleton is still broken, but Bison should not
10281 choke on a bad muscle 'syntax'.
10282 * src/bison.simple: Add a section directive. Put braces around muscle
10283 names.
10285 * src/files.h (strsuffix, stringappend): Add declarations.
10286 (tab_extension): Add declaration.
10287 (short_base_name): Add declaration.
10289 * src/files.c (strsuffix, stringappend): No longer static. These
10290 functions are used in the skeleton parser.
10291 (tab_extension): New.
10292 (compute_base_names): Use the computations done in this function
10293 to guess if the generated parsers should have '.tab' in their
10294 names.
10295 (short_base_name): No longer static.
10297 * src/output.c (output_skeleton): New.
10298 (output): Disable call to output_master_parser, and give a try to
10299 a new skeleton handling system.
10300 (guards_output, actions_output): No longer static.
10301 (token_definitions_output, get_lines_number): No longer static.
10303 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
10305 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
10306 parse-skel.y.
10308 * src/parse-skel.y: New file.
10309 * src/scan-skel.l: New file.
10311 2001-12-29 Akim Demaille <akim@epita.fr>
10313 %name-prefix is broken.
10315 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10316 Adjust all dependencies.
10317 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10318 %name-prefix.
10320 Renaming yylval but not yylloc is not consistent. Now we do.
10322 * src/bison.simple: Prefix yylloc if used.
10323 * doc/bison.texinfo (Decl Summary): Document that.
10325 2001-12-29 Akim Demaille <akim@epita.fr>
10327 * doc/bison.texinfo: Promote `%long-directive' over
10328 `%long_directive'.
10329 Remove all references to fixed-output-files, yacc is enough.
10331 2001-12-29 Akim Demaille <akim@epita.fr>
10333 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10334 user prologue. These are defaults.
10335 * tests/actions.at (Mid-rule actions): Make sure the user can
10336 define YYDEBUG and YYERROR_VERBOSE.
10338 2001-12-29 Akim Demaille <akim@epita.fr>
10340 * src/output.c (header_output): Don't forget to export YYLTYPE and
10341 yylloc.
10342 * tests/headers.at (export YYLTYPE): New, make sure it does.
10343 * tests/regression.at (%union and --defines, Invalid CPP headers):
10344 Move to...
10345 * tests/headers.at: here.
10347 2001-12-29 Akim Demaille <akim@epita.fr>
10349 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
10351 2001-12-29 Akim Demaille <akim@epita.fr>
10353 * tests/actions.at (Mid-rule actions): Output on a single line
10354 instead of several.
10356 2001-12-29 Akim Demaille <akim@epita.fr>
10358 * doc/bison.texinfo: Formatting changes.
10360 2001-12-29 Akim Demaille <akim@epita.fr>
10362 Don't store the token defs in a muscle, just be ready to output it
10363 on command. Now possible via `symbols'. Fixes a memory leak.
10365 * src/output.c (token_definitions_output): New.
10366 (output_parser, header_output): Use it.
10367 * src/reader.c (symbols_save): Remove.
10369 2001-12-29 Akim Demaille <akim@epita.fr>
10371 * src/bison.simple: Do not provide a default for YYSTYPE and
10372 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10373 default.
10375 2001-12-29 Akim Demaille <akim@epita.fr>
10377 Mid-rule actions are simply... ignored!
10379 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10380 the empty-rule associated to the dummy symbol, not to the host
10381 rule.
10382 * tests/actions.at (Mid-rule actions): New.
10384 2001-12-29 Akim Demaille <akim@epita.fr>
10386 Memory leak.
10388 * src/reader.c (reader): Free grammar.
10390 2001-12-29 Akim Demaille <akim@epita.fr>
10392 Memory leak.
10394 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10395 since it allocates it for each state, although only one is needed.
10396 (allocate_storage): Do it here.
10398 2001-12-29 Akim Demaille <akim@epita.fr>
10400 * src/options.h, src/options.c (create_long_option_table): Rename
10401 as...
10402 (long_option_table_new): this, with a clearer prototype.
10403 (percent_table): Remove, unused,
10404 * src/getargs.c (getargs): Adjust.
10406 2001-12-29 Akim Demaille <akim@epita.fr>
10408 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
10409 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
10410 as states.
10412 2001-12-29 Akim Demaille <akim@epita.fr>
10414 * src/lalr.c (build_relations): Rename `states' as `states1'.
10415 Sorry, I don't understand exactly what it is, no better name...
10417 2001-12-29 Akim Demaille <akim@epita.fr>
10419 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10420 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
10421 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
10422 as rules.
10424 2001-12-29 Akim Demaille <akim@epita.fr>
10426 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
10427 ago.
10429 2001-12-29 Akim Demaille <akim@epita.fr>
10431 * src/reader.c, src/reader.h (user_toknums): Remove.
10432 Adjust all users to use symbols[i]->user_token_number.
10434 2001-12-29 Akim Demaille <akim@epita.fr>
10436 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
10437 Adjust all users to use symbols[i]->prec or ->assoc.
10439 2001-12-29 Akim Demaille <akim@epita.fr>
10441 * src/reader.c, src/reader.h (tags): Remove.
10442 Adjust all users to use symbols[i]->tag.
10444 2001-12-29 Akim Demaille <akim@epita.fr>
10446 * src/gram.h, src/gram.c (symbols): New, similar to state_table
10447 and rule_table.
10448 * src/reader.c (packsymbols): Fill this table.
10449 Drop sprec.
10450 * src/conflicts.c (resolve_sr_conflict): Adjust.
10451 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10452 single table.
10453 Use symbols[i]->tag instead of tags[i].
10455 2001-12-29 Akim Demaille <akim@epita.fr>
10457 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10458 In addition, put a comment in there, to replace...
10459 * tests/regression.at (%union and C comments): Remove.
10461 2001-12-29 Akim Demaille <akim@epita.fr>
10463 * tests/regression.at (Web2c Actions): Blindly move the actual
10464 output as expected output. The contents *seem* right to me, but I
10465 can't pretend reading perfectly parser tables... Nonetheless, all
10466 the other tests pass correctly, the table look OK, even though the
10467 presence of `$axiom' is to be noted: AFAICS it is useless (but
10468 harmless).
10470 2001-12-29 Akim Demaille <akim@epita.fr>
10472 * src/reader.c (readgram): Don't add the rule 0 if there were no
10473 rules read. In other words, add it _after_ having performed
10474 grammar sanity checks.
10475 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
10477 2001-12-29 Akim Demaille <akim@epita.fr>
10479 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
10480 visible, and some states have now a different number.
10482 2001-12-29 Akim Demaille <akim@epita.fr>
10484 * src/reader.c (readgram): Bind the initial rule's lineno to that
10485 of the first rule.
10486 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
10487 (Solved SR Conflicts): Adjust rule 0's line number.
10489 2001-12-29 Akim Demaille <akim@epita.fr>
10491 Fix the `GAWK Grammar' failure.
10493 * src/LR0.c (final_state): Initialize to -1 so that we do compute
10494 the reductions of the first state which was mistakenly confused
10495 with the final state because precisely final_state was initialized
10496 to 0.
10497 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
10498 now noticed by Bison.
10499 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
10500 have a reduction on $default.
10502 2001-12-29 Akim Demaille <akim@epita.fr>
10504 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
10505 rule line numbers.
10506 * src/closure.c (print_closure): Likewise.
10507 * src/derives.c (print_derives): Likewise.
10508 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
10509 now.
10511 2001-12-29 Akim Demaille <akim@epita.fr>
10513 * src/lalr.c (lookaheads_print): New.
10514 (lalr): Call it when --trace-flag.
10515 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
10516 are dumped.
10518 2001-12-29 Akim Demaille <akim@epita.fr>
10520 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
10521 when walking through ritem, even via rule->rhs.
10522 * src/reduce.c (dump_grammar, useful_production, reduce_output)
10523 (useful_production, useless_nonterminals): Likewise.
10524 (reduce_grammar_tables): Likewise, plus update nritems.
10525 * src/nullable.c (set_nullable): Likewise.
10526 * src/lalr.c (build_relations): Likewise.
10527 * tests/sets.at (Nullable): Adjust.
10528 Fortunately, now, the $axiom is no longer nullable.
10530 2001-12-29 Akim Demaille <akim@epita.fr>
10532 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
10533 the 0-sentinel.
10534 * src/gram.c (ritem_longest_rhs): Likewise.
10535 * src/reduce.c (nonterminals_reduce): Likewise.
10536 * src/print_graph.c (print_graph): Likewise.
10537 * src/output.c (output_rule_data): Likewise.
10538 * src/nullable.c (set_nullable): Likewise.
10540 2001-12-29 Akim Demaille <akim@epita.fr>
10542 * src/output.c: Comment changes.
10544 2001-12-27 Paul Eggert <eggert@twinsun.com>
10546 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
10547 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
10548 Sparc, as they were causing more porting problems than the
10549 (minor) performance improvement was worth.
10551 Also, catch up with 1.31's YYSTD.
10553 2001-12-27 Akim Demaille <akim@epita.fr>
10555 * src/output.c (output_gram): Rely on nritems, not the
10556 0-sentinel. See below.
10557 Use -1 as separator, not 0.
10558 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
10559 Rely on -1 as separator in yyrhs, instead of 0.
10560 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
10561 twice `Now at end of input', therefore there are two lines less to
10562 expect.
10564 2001-12-27 Akim Demaille <akim@epita.fr>
10566 * tests/regression.at (Unresolved SR Conflicts):
10567 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
10568 below.
10570 2001-12-27 Akim Demaille <akim@epita.fr>
10572 * src/LR0.c (new_state): Recognize the final state by the fact it
10573 is reached by eoftoken.
10574 (insert_start_shifting_state, insert_eof_shifting_state)
10575 (insert_accepting_state, augment_automaton): Remove, since now
10576 these states are automatically computed from the initial state.
10577 (generate_states): Adjust.
10578 * src/print.c: When reporting a rule number to the user, substract
10579 1, so that the axiom rule is rule 0, and the first user rule is 1.
10580 * src/reduce.c: Likewise.
10581 * src/print_graph.c (print_core): For the time being, just as for
10582 the report, depend upon --trace-flags to dump the full set of
10583 items.
10584 * src/reader.c (readgram): Once the grammar read, insert the rule
10585 0: `$axiom: START-SYMBOL $'.
10586 * tests/set.at: Adjust: rule 0 is now displayed, and since the
10587 number of the states has changed (the final state is no longer
10588 necessarily the last), catch up.
10590 2001-12-27 Akim Demaille <akim@epita.fr>
10592 Try to make the use of the eoftoken valid. Given that its value
10593 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
10594 is used instead of > 0 where appropriate, (ii), depend upon nritems
10595 instead of the 0-sentinel.
10597 * src/gram.h, src/gram.c (nritems): New.
10598 Expected to be duplication of nitems, but for the time being...
10599 * src/reader.c (packgram): Assert nritems and nitems are equal.
10600 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
10601 * src/closure.c (print_closure, print_fderives): Likewise.
10602 * src/gram.c (ritem_print): Likewise.
10603 * src/print.c (print_core, print_grammar): Likewise.
10604 * src/print_graph.c: Likewise.
10606 2001-12-27 Akim Demaille <akim@epita.fr>
10608 * src/main.c (main): If there are complains after grammar
10609 reductions, then output the report anyway if requested, then die.
10610 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
10611 * src/reader.c (eoftoken): New.
10612 (parse_token_decl): If the token being defined has value `0', it
10613 is the eoftoken.
10614 (packsymbols): No longer hack `tags' to insert `$' by hand.
10615 Be sure to preserve the value of the eoftoken.
10616 (reader): Make sure eoftoken is defined.
10617 Initialize nsyms to 0: now eoftoken is created just like the others.
10618 * src/print.c (print_grammar): Don't special case the eof token.
10619 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
10620 lie anyway, albeit pleasant.
10621 * tests/calc.at: Exercise error messages with eoftoken.
10622 Change the grammar so that empty input is invalid.
10623 Adjust expectations.
10624 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
10626 2001-12-27 Akim Demaille <akim@epita.fr>
10628 * configure.in: Check the protos of strchr ans strspn.
10629 Replace strchr if needed.
10630 * src/system.h: Provide the protos of strchr, strspn and memchr if
10631 missing.
10632 * lib/strchr.c: New.
10633 * src/reader.c (symbols_save): Use strchr.
10635 2001-12-27 Akim Demaille <akim@epita.fr>
10637 * src/print.c, src/print_graph.c (escape): New.
10638 Use it to quote the TAGS outputs.
10639 * src/print_graph.c (print_state): Now errors are in red, and
10640 reductions in green.
10641 Prefer high to wide: output the state number on a line of its own.
10643 2001-12-27 Akim Demaille <akim@epita.fr>
10645 * src/state.h, src/state.c (reductions_new): New.
10646 * src/LR0.c (set_state_table): Let all the states have a
10647 `reductions', even if reduced to 0.
10648 (save_reductions): Adjust.
10649 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
10650 * src/print.c (print_reductions, print_actions): Adjust.
10651 * src/output.c (action_row): Adjust.
10653 2001-12-27 Akim Demaille <akim@epita.fr>
10655 * src/state.h, src/state.c (errs_new, errs_dup): New.
10656 * src/LR0.c (set_state_table): Let all the states have an errs,
10657 even if reduced to 0.
10658 * src/print.c (print_errs, print_reductions): Adjust.
10659 * src/output.c (output_actions, action_row): Adjust.
10660 * src/conflicts.c (resolve_sr_conflict): Adjust.
10662 2001-12-27 Akim Demaille <akim@epita.fr>
10664 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
10666 2001-12-27 Akim Demaille <akim@epita.fr>
10668 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
10669 * src/print.c: here.
10670 (lookaheadset, shiftset): New, used as additional storage by
10671 print_reductions.
10672 (print_results): Adjust.
10673 (print_shifts, print_gotos, print_errs): New, extracted from...
10674 (print_actions): here.
10675 * src/print_graph.c (print_actions): Remove dead code.
10677 2001-12-27 Akim Demaille <akim@epita.fr>
10679 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
10680 `$n' and `@n'.
10682 2001-12-27 Akim Demaille <akim@epita.fr>
10684 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
10685 (build_relations): Adjust.
10687 2001-12-27 Akim Demaille <akim@epita.fr>
10689 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
10690 duplication.
10692 2001-12-27 Akim Demaille <akim@epita.fr>
10694 * src/reader.c (packgram): Catch nitems overflows.
10696 2001-12-27 Akim Demaille <akim@epita.fr>
10698 * src/files.c, src/files.h (guard_obstack): Remove.
10699 * src/output.c (output): Adjust.
10700 * src/reader.c (parse_braces): New, factoring...
10701 (copy_action, copy_guard): these two which are renamed as...
10702 (parse_action, parse_guard): these.
10703 As a voluntary consequence, using braces around guards is now
10704 mandatory.
10706 2001-12-27 Akim Demaille <akim@epita.fr>
10708 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
10709 * src/reader.c (symbol_list): `guard' and `guard_line' are new
10710 members.
10711 (symbol_list_new): Adjust.
10712 (copy_action): action_line is the first line, not the last.
10713 (copy_guard): Just as for actions, store the `action' only, not
10714 the switch/case/break flesh.
10715 Don't parse the user action that might follow the guard, let...
10716 (readgram): do it, i.e., now, there can be an action after a
10717 guard.
10718 In other words the guard is just explicitly optional.
10719 (packgram): Adjust.
10720 * src/output.c (guards_output): New.
10721 (output_parser): Call it when needed.
10722 (output): Also free the guard and attrs obstacks.
10723 * src/files.c, src/files.h (obstack_save): Remove.
10724 (output_files): Remove.
10725 As a result, if one needs the former `.act' file, using an
10726 appropriate skeleton which requires actions and guards is now
10727 required.
10728 * src/main.c (main): Adjust.
10729 * tests/semantic.at: New.
10730 * tests/regression.at: Use `input.y' as input file name.
10731 Avoid 8+3 problems by requiring input.c when the test needs the
10732 parser.
10734 2001-12-27 Akim Demaille <akim@epita.fr>
10736 * src/reader.c (symbol_list_new): Be sure to initialize all the
10737 fields.
10739 2001-12-27 Akim Demaille <akim@epita.fr>
10741 All the hacks using a final pseudo state are now useless.
10743 * src/LR0.c (set_state_table): state_table holds exactly nstates.
10744 * src/lalr.c (nLA): New.
10745 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
10746 instead of lookaheadsp from the pseudo state (nstate + 1).
10748 2001-12-27 Akim Demaille <akim@epita.fr>
10750 * src/output.c (action_row, token_actions): Use a state_t instead
10751 of a integer, and nlookaheads instead of the following state's
10752 lookaheadsp.
10754 2001-12-27 Akim Demaille <akim@epita.fr>
10756 * src/conflicts.c (log_resolution, flush_shift)
10757 (resolve_sr_conflict, set_conflicts, solve_conflicts)
10758 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
10759 (conflicts_print, print_reductions): Use a state_t instead of an
10760 integer when referring to a state.
10761 As much as possible, depend upon nlookaheads, instead of the
10762 `lookaheadsp' member of the following state (since lookaheads of
10763 successive states are successive, the difference between state n + 1
10764 and n served as the number of lookaheads for state n).
10765 * src/lalr.c (add_lookback_edge): Likewise.
10766 * src/print.c (print_core, print_actions, print_state)
10767 (print_results): Likewise.
10768 * src/print_graph.c (print_core, print_actions, print_state)
10769 (print_graph): Likewise.
10770 * src/conflicts.h: Adjust.
10772 2001-12-27 Akim Demaille <akim@epita.fr>
10774 * src/bison.hairy: Formatting/comment changes.
10775 ANSIfy.
10776 Remove `register' indications.
10777 Add plenty of `static'.
10779 2001-12-27 Akim Demaille <akim@epita.fr>
10781 * src/output.c (prepare): Drop the muscle `ntbase' which
10782 duplicates ntokens.
10783 * src/bison.simple: Formatting/comment changes.
10784 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
10785 is an undocumented synonym.
10787 2001-12-22 Akim Demaille <akim@epita.fr>
10789 * src/output.c (output_table_data): Change the prototype to use
10790 `int' for array ranges: some invocations do pass an int, not a
10791 short.
10792 Reported by Wayne Green.
10794 2001-12-22 Akim Demaille <akim@epita.fr>
10796 Some actions of web2c.y are improperly triggered.
10797 Reported by Mike Castle.
10799 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
10800 * tests/regression.at (Web2c): Rename as...
10801 (Web2c Report): this.
10802 (Web2c Actions): New.
10804 2001-12-22 Akim Demaille <akim@epita.fr>
10806 Reductions in web2c.y are improperly reported.
10807 Reported by Mike Castle.
10809 * src/conflicts.c (print_reductions): Fix.
10810 * tests/regression.at (Web2c): New.
10812 2001-12-18 Akim Demaille <akim@epita.fr>
10814 Some host fail on `assert (!"foo")', which expands to
10815 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
10816 Reported by Nelson Beebee.
10818 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
10819 `#define it_succeeded 0' and `assert (it_succeeded)'.
10821 2001-12-17 Marc Autret <autret_m@epita.fr>
10823 * src/bison.simple: Don't hard code the skeleton line and filename.
10824 * src/output.c (output_parser): Rename 'line' as 'output_line'.
10825 New line counter 'skeleton_line' (skeleton-line muscle).
10827 2001-12-17 Paul Eggert <eggert@twinsun.com>
10829 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
10830 YYDEBUG must be defined to a nonzero value.
10832 * src/bison.simple (yytname): Do not assume that the user defines
10833 YYDEBUG to a properly parenthesized expression.
10835 2001-12-17 Akim Demaille <akim@epita.fr>
10837 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
10838 nlookaheads is a new member.
10839 Adjust all users.
10840 * src/lalr.h (nlookaheads): Remove this orphan declaration.
10841 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
10842 state.
10844 2001-12-17 Akim Demaille <akim@epita.fr>
10846 * src/files.h, src/files.c (open_files, close_files): Remove.
10847 * src/main.c (main): Don't open/close files, nor invoke lex_free,
10848 let...
10849 * src/reader.c (reader): Do it.
10851 2001-12-17 Akim Demaille <akim@epita.fr>
10853 * src/conflicts.c (print_reductions): Formatting changes.
10855 2001-12-17 Akim Demaille <akim@epita.fr>

10861 2001-12-17 Akim Demaille <akim@epita.fr>
10863 * src/output.c (output_obstack): Be static and rename as...
10864 (format_obstack): this, to avoid any confusion with files.c's
10865 output_obstack.
10866 * src/reader.h (muscle_obstack): Move to...
10867 * src/output.h: here, since it's defined in output.c.
10869 2001-12-17 Akim Demaille <akim@epita.fr>
10871 * src/output.c (action_row, save_column, default_goto)
10872 (sort_actions, matching_state, pack_vector): Better variable
10873 locality.
10875 2001-12-17 Akim Demaille <akim@epita.fr>
10877 * src/output.c: Various formatting changes.
10879 2001-12-17 Akim Demaille <akim@epita.fr>
10881 * src/files.c (output_files): Free the output_obstack.
10882 * src/main.c (main): Call print and print_graph conditionally.
10883 * src/print.c (print): Work unconditionally.
10884 * src/print_graph.c (print_graph): Work unconditionally.
10885 * src/conflicts.c (log_resolution): Output only if verbose_flag.
10887 2001-12-16 Marc Autret <autret_m@epita.fr>
10889 * src/output.c (actions_output): Fix. When we use %no-lines,
10890 there is one less line per action.
10892 2001-12-16 Marc Autret <autret_m@epita.fr>
10894 * src/bison.simple: Remove a useless #line directive.
10895 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
10896 * src/output.c (get_lines_number): New.
10897 (output_parser): Adjust, now takes care about the lines of a
10898 output muscles.
10899 Fix line numbering.
10900 (actions_output): Computes the number of lines taken by actions.
10901 (output_master_parser): Insert new skeleton which is the name of
10902 the output parser file name.
10904 2001-12-15 Marc Autret <autret_m@epita.fr>
10906 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
10908 2001-12-15 Marc Autret <autret_m@epita.fr>
10910 * src/output.c (output_gram): Keep track of the hairy one.
10912 2001-12-15 Akim Demaille <akim@epita.fr>
10914 Make `make distcheck' work.
10916 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
10917 system.h which uses libgettext.h.
10919 2001-12-15 Akim Demaille <akim@epita.fr>
10921 * src/nullable.c (set_nullable): Useless rules must be skipped,
10922 otherwise, since we range over their symbols, we might look at a
10923 nonterminal which no longer ``exists'', i.e., it is not counted in
10924 `nvars', hence we overflow our arrays.
10926 2001-12-15 Akim Demaille <akim@epita.fr>
10928 The header can also be produced directly, without any obstack!
10929 Yahoo!
10931 * src/files.c, src/files.h (defines_obstack): Remove.
10932 (compute_header_macro): Global.
10933 (defines_obstack_save): Remove.
10934 * src/reader.c (parse_union_decl): No longer output to
10935 defines_obstack: its content can be found in the `stype' muscle
10936 anyway.
10937 (output_token_translations): Merge into...
10938 (symbols_output): this.
10939 Rename as...
10940 (symbols_save): this.
10941 (reader): Adjust.
10942 * src/output.c (header_output): New.
10943 (output): Call it.
10945 2001-12-15 Akim Demaille <akim@epita.fr>
10947 * src/reader.c (parse_union_decl): Instead of handling two obstack
10948 simultaneously, use one to define the `stype' muscle, and use the
10949 value of the latter to fill defines_obstack.
10950 (copy_comment): Remove.
10951 (copy_comment2): Work for a single obstack.
10952 Rename as...
10953 (copy_comment): this.
10955 2001-12-15 Akim Demaille <akim@epita.fr>
10957 * src/lex.c, src/lex.h (xgetc): No longer static.
10958 * src/reader.c (parse_union_decl): Revamp.
10960 2001-12-15 Akim Demaille <akim@epita.fr>
10962 Still making progress in separating Bison into (i) input, (ii)
10963 process, (iii) output: now we can directly output the parser file
10964 without using table_obstack at all.
10966 * src/files.c, src/files.h (table_obstack): Bye bye.
10967 (parser_file_name): New.
10968 * src/files.c (compute_output_file_names): Compute it.
10969 * src/output.c (actions_output, output_parser)
10970 (output_master_parser): To a file instead of an obstack.
10972 2001-12-15 Akim Demaille <akim@epita.fr>
10974 Attach actions to rules, instead of pre-outputting them to
10975 actions_obstack.
10977 * src/gram.h (rule_t): action and action_line are new members.
10978 * src/reader.c (symbol_list): Likewise.
10979 (copy_action): Save the actions within the rule.
10980 (packgram): Save them in rule_table.
10981 * src/output.c (actions_output): New.
10982 (output_parser): Use it on `%%actions'.
10983 (output_rule_data): Don't free rule_table.
10984 (output): Do it.
10985 (prepare): Don't save the `action' muscle.
10986 * src/bison.simple: s/%%action/%%actions/.
10988 2001-12-15 Akim Demaille <akim@epita.fr>
10990 * src/reader.c (copy_action): When --yacc, don't append a `;'
10991 to the user action: let it fail if lacking.
10992 Suggested by Arnold Robbins and Tom Tromey.
10994 2001-12-14 Akim Demaille <akim@epita.fr>
10996 * src/lex.c (literalchar): Simply return the char you decoded, non
10997 longer mess around with obstacks and int pointers.
10998 Adjust all callers.
11000 2001-12-14 Akim Demaille <akim@epita.fr>
11002 * src/lex.c (literalchar): Don't escape the special characters,
11003 just decode them, and keep them as char (before, eol was output as
11004 the 2 char string `\n' etc.).
11005 * src/output.c (output_rule_data): Use quotearg to output the
11006 token strings.
11008 2001-12-13 Paul Eggert <eggert@twinsun.com>
11010 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11011 Do not infringe on the global user namespace when using C++.
11012 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11013 All uses of `fprintf' and `stderr' changed.
11015 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11017 2001-12-13 Akim Demaille <akim@epita.fr>
11019 The computation of nullable is broken: it doesn't handle empty
11020 RHS's properly.
11022 * tests/torture.at (GNU AWK Grammar): New.
11023 * tests/sets.at (Nullable): New.
11024 * src/nullable.c (set_nullable): Instead of blindly looping over
11025 `ritems', loop over the rules, and then over their rhs's.
11027 Work around Autotest bugs.
11029 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11030 frame, because Autotest understand lines starting with a `+' as
11031 traces from the shell. Then, they are not processed properly.
11032 Admittedly an Autotest bug, but we don't have time to wait for
11033 Autotest to catch up.
11034 * tests/regression.at (Broken Closure): Adjust to the new table
11035 frames.
11036 Move to...
11037 * tests/sets.at: here.
11039 2001-12-13 Akim Demaille <akim@epita.fr>
11041 * src/closure.c (closure): Use nrules instead of playing tricks
11042 with BITS_PER_WORD.
11044 2001-12-13 Akim Demaille <akim@epita.fr>
11046 * src/print.c (print_actions): Output the handling of `$' as the
11047 traces do: shifting the token EOF. Before EOF was treated as a
11048 nonterminal.
11049 * tests/regression.at: Adjust some tests.
11050 * src/print_graph.c (print_core): Complete the set of items via
11051 closure. The next-to-final and final states are still unsatisfying,
11052 but that's to be addressed elsewhere.
11053 No longer output the rule numbers, but do output the state number.
11054 A single loop for the shifts + gotos is enough, but picked a
11055 distinct color for each.
11056 (print_graph): Initialize and finalize closure.
11058 2001-12-13 Akim Demaille <akim@epita.fr>
11060 * src/reader.c (readgram): Remove dead code, an strip useless
11061 braces.
11062 (get_type): Remove, unused.
11064 2001-12-12 Akim Demaille <akim@epita.fr>
11066 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11067 on that of lib/error.c.
11069 2001-12-12 Akim Demaille <akim@epita.fr>
11071 Some hosts don't like `/' in includes.
11073 * src/system.h: Include libgettext.h without qualifying the path.
11074 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11075 $(top_srcdir).
11077 2001-12-11 Marc Autret <autret_m@epita.fr>
11079 * src/output.c (output_parser): Remove useless muscle.
11081 2001-12-11 Marc Autret <autret_m@epita.fr>
11083 * src/bison.simple: Remove #line just before %%epilogue. It
11084 is now handled in ...
11085 * src/reader.c (read_additionnal_code): Add the output of a
11086 #line for the epilogue.
11088 2001-12-10 Marc Autret <autret_m@epita.fr>
11090 * src/reader.c (copy_definition): Re-use CPP-outed code which
11091 replace precedent remove.
11092 * src/bison.simple: Remove #line before %%prologue because
11093 %%input-line is wrong at this time.
11095 2001-12-10 Marc Autret <autret_m@epita.fr>
11097 * src/reader.c (symbols_output): Clean up.
11098 * src/output.c (output_gram, output): Clean up.
11100 2001-12-10 Akim Demaille <akim@epita.fr>
11102 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11103 * src/LR0.c (set_state_table): here.
11104 * src/lalr.c (lalr): Call it.
11106 2001-12-10 Akim Demaille <akim@epita.fr>
11108 * src/state.h (shifts): Remove the `number' member: shifts are
11109 attached to state, hence no longer need to be labelled with a
11110 state number.
11112 2001-12-10 Akim Demaille <akim@epita.fr>
11114 Now that states have a complete set of members, the linked list of
11115 shifts is useless: just fill directly the state's shifts member.
11117 * src/state.h (shifts): Remove the `next' member.
11118 * src/LR0.c (first_state, last_state): Remove.
11119 Adjust the callers.
11120 (augment_automaton): Don't look for the shifts that must be added
11121 a shift on EOF: it is those of the state we looked for! But now,
11122 since shifts are attached, it is no longer needed to looking
11123 merely by its id: its number.
11125 2001-12-10 Akim Demaille <akim@epita.fr>
11127 * src/LR0.c (augment_automaton): Better variable locality.
11128 Remove an impossible branch: if there is a state corresponding to
11129 the start symbol being shifted, then there is shift for the start
11130 symbol from the initial state.
11132 2001-12-10 Akim Demaille <akim@epita.fr>
11134 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11135 only when appropriate: when insert_start_shifting_state' is not
11136 invoked.
11137 * tests/regression.at (Rule Line Numbers): Adjust.
11139 2001-12-10 Akim Demaille <akim@epita.fr>
11141 * src/LR0.c (augment_automaton): Now that all states have shifts,
11142 merge the two cases addition shifts to the initial state.
11144 2001-12-10 Akim Demaille <akim@epita.fr>
11146 * src/lalr.c (set_state_table): Move to...
11147 * src/LR0.c: here.
11148 * src/lalr.c (lalr): Don't call it...
11149 * src/LR0.c (generate_states): do it.
11150 * src/LR0.h (first_state): Remove, only the table is used.
11152 2001-12-10 Akim Demaille <akim@epita.fr>
11154 * src/LR0.h (first_shift, first_reduction): Remove.
11155 * src/lalr.c: Don't use first_shift: find shifts through the
11156 states.
11158 2001-12-10 Akim Demaille <akim@epita.fr>
11160 * src/LR0.c: Attach shifts to states as soon as they are
11161 computed.
11162 * src/lalr.c (set_state_table): Instead of assigning shifts to
11163 state, just assert that the mapping was properly done.
11165 2001-12-10 Akim Demaille <akim@epita.fr>
11167 * src/LR0.c (insert_start_shift): Rename as...
11168 (insert_start_shifting_state): this.
11169 (insert_eof_shifting_state, insert_accepting_state): New.
11170 (augment_automaton): Adjust.
11171 Better locality of the variables.
11172 When looking if the start_symbol is shifted from the initial
11173 state, using `while (... symbol != start_symbol ...)' sounds
11174 better than `while (... symbol < start_symbol ...)': If fail
11175 to see how the order between symbols could be relevant!
11177 2001-12-10 Akim Demaille <akim@epita.fr>
11179 * src/getargs.h: Don't declare `spec_name_prefix' and
11180 `spec_file_prefix', declared by src/files.h.
11181 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11182 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11183 * src/output.c (prepare): Adjust.
11184 * src/reader.c (symbols_output): Likewise.
11185 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11187 2001-12-10 Akim Demaille <akim@epita.fr>
11189 * src/muscle_tab.c (muscle_init): NULL is a better default than
11190 `"0"'.
11192 2001-12-10 Akim Demaille <akim@epita.fr>
11194 * src/reader.c (reader): Calling symbols_output once is enough.
11196 2001-12-10 Akim Demaille <akim@epita.fr>
11198 Now that states have a complete set of members, the linked list of
11199 reductions is useless: just fill directly the state's reductions
11200 member.
11202 * src/state.h (struct reductions): Remove member `number' and
11203 `next'.
11204 * src/LR0.c (first_reduction, last_reduction): Remove.
11205 (save_reductions): Don't link the new reductions, store them in
11206 this_state.
11207 * src/lalr.c (set_state_table): No need to attach reductions to
11208 states, it's already done.
11209 * src/output.c (output_actions): No longer free the shifts, then
11210 the reductions, then the states: free all the states and their
11211 members.
11213 2001-12-10 Akim Demaille <akim@epita.fr>
11215 * src/options.c (OPTN, DRTV, BOTH): New.
11216 (option_table): Use them.
11218 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11219 the job of system.h.
11220 * src/options.c: Don't include stdio.h and xalloc.h for the same
11221 reasons.
11223 2001-12-10 Akim Demaille <akim@epita.fr>
11225 * src/output.c (output, prepare): Make sure the values of the
11226 muscles `action' and `prologue' are 0-terminated.
11228 2001-12-10 Akim Demaille <akim@epita.fr>
11230 Clean up GCC warnings.
11232 * src/reader.c (copy_action): `buf' is not used.
11233 (parse_skel_decl): Be static.
11234 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11235 * src/options.h (create_long_option_table): Have a real prototype.
11236 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11237 (hash_delete_at): Return const void *.
11238 Adjust casts to preserve the const.
11240 2001-12-10 Akim Demaille <akim@epita.fr>
11242 * configure.in: Require 2.52g.
11243 M4 is not needed, but AUTOM4TE is.
11244 * m4/m4.m4: Remove.
11245 * tests/Makefile.am: Adjust.
11247 2001-12-10 Akim Demaille <akim@epita.fr>
11249 One structure for states is enough, even though theoretically
11250 there are LR(0) states and LALR(1) states.
11252 * src/lalr.h (state_t): Remove.
11253 (state_table): Be state_t **, not state_t *.
11254 * src/state.h (core, CORE_ALLOC): Rename as...
11255 (state_t, STATE_ALLOC): this.
11256 Add the LALR(1) members: shifts, reductions, errs.
11257 * src/LR0.c (state_table): Rename as...
11258 (state_hash): this, to avoid name clashes with the global
11259 `state_table'.
11260 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11261 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11263 2001-12-10 Akim Demaille <akim@epita.fr>
11265 Bison dumps core on bash.y.
11266 Reported by Pascal Bart.
11268 * src/warshall.c (bitmatrix_print): New.
11269 (TC): Use it.
11270 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11271 j must be the outer loop.
11272 * tests/regression.at (Broken Closure): New.
11274 2001-12-05 Akim Demaille <akim@epita.fr>
11276 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
11277 its argument.
11278 Reported by Peter Hamorsky.
11280 2001-12-05 Akim Demaille <akim@epita.fr>
11282 * src/conflicts.c (err_table): Remove.
11283 (resolve_sr_conflict): Adjust.
11284 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
11285 Rename as...
11286 (state_t.reductions, state_t.shifts): this.
11288 2001-12-05 Akim Demaille <akim@epita.fr>
11290 * src/reduce.c (reduce_grammar_tables): No longer disable the
11291 removal of useless rules via CPP but via `if (0)', so that the
11292 compiler still check the code is valid.
11293 For instance, it should have noticed `rline' no longer exists: use
11294 the `line' member of rule_t.
11295 * src/gram.c (dummy, rline): Remove, unused.
11297 2001-12-05 Akim Demaille <akim@epita.fr>
11299 * src/output.c (pack_vector): Use assert, not berror.
11300 * src/main.c (berror): Remove, unused.
11302 2001-12-05 Akim Demaille <akim@epita.fr>
11304 New experimental feature: if --verbose --trace output all the
11305 items of a state, not only its kernel.
11307 * src/print.c (print_core): If `trace_flag', then invoke closure
11308 before outputting the items of the state (print_core is no longer
11309 a correct name them).
11310 (print_results): Invoke new_closure/free_closure if needed.
11312 2001-12-05 Akim Demaille <akim@epita.fr>
11314 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
11315 * src/closure.c, src/closure.h (itemsetsize): Rename as...
11316 (nitemset): for consistency with the rest of the project.
11318 2001-12-05 Akim Demaille <akim@epita.fr>
11320 * src/closure.c (print_closure): Improve.
11321 (closure): Use it for printing input and output.
11323 2001-12-05 Akim Demaille <akim@epita.fr>
11325 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11326 indexed by nonterminals.
11328 2001-12-05 Akim Demaille <akim@epita.fr>
11330 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
11331 what it was!).
11332 * src/warshall.h: Remove accidental duplication of the content.
11334 2001-12-05 Akim Demaille <akim@epita.fr>
11336 * src/closure.c (set_fderives): De-obfuscate.
11338 2001-12-05 Akim Demaille <akim@epita.fr>
11340 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
11342 2001-12-05 Akim Demaille <akim@epita.fr>
11344 * src/closure.c (set_firsts): De-obfuscate.
11346 2001-12-05 Akim Demaille <akim@epita.fr>
11348 * src/output.c (action_row): De-obfuscate
11349 using the good o' techniques: arrays not pointers, variable
11350 locality, BITISSET, RESETBIT etc.
11352 2001-12-05 Akim Demaille <akim@epita.fr>
11354 Pessimize the code to simplify it: from now on, all the states
11355 have a valid SHIFTS, which NSHIFTS is possibly 0.
11357 * src/LR0.c (shifts_new): Be global and move to..
11358 * src/state.c, src/state.h: here.
11359 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
11360 * src/print_graph: Adjust.
11362 2001-12-05 Akim Demaille <akim@epita.fr>
11364 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
11365 * src/conflicts.c: Use it.
11366 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11367 incorrectly ``simplified''.
11369 2001-12-05 Akim Demaille <akim@epita.fr>
11371 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11372 using the good o' techniques: arrays not pointers, variable
11373 locality, BITISSET, RESETBIT etc.
11375 2001-12-05 Akim Demaille <akim@epita.fr>
11377 * src/state.h (SHIFT_SYMBOL): New.
11378 * src/conflicts.c: Use it to deobfuscate.
11380 2001-12-05 Akim Demaille <akim@epita.fr>
11382 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
11383 (print_reductions): De-obfuscate using the good o' techniques:
11384 arrays not pointers, variable locality, BITISSET.
11386 2001-12-05 Akim Demaille <akim@epita.fr>
11388 * src/conflicts.c (print_reductions): Arrays, not pointers.
11389 Use BITISSET.
11391 2001-12-05 Akim Demaille <akim@epita.fr>
11393 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11395 2001-12-05 Akim Demaille <akim@epita.fr>
11397 * src/conflicts.c (print_reductions): Improve variable locality.
11399 2001-12-05 Akim Demaille <akim@epita.fr>
11401 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11403 2001-12-05 Akim Demaille <akim@epita.fr>
11405 * src/conflicts.c (print_reductions): Improve variable locality.
11407 2001-12-05 Akim Demaille <akim@epita.fr>
11409 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
11410 * src/lalr.c: Use them.
11412 2001-12-05 Akim Demaille <akim@epita.fr>
11414 * src/LR0.c (augment_automaton): Formatting changes.
11415 Better variable locality.
11417 2001-12-05 Akim Demaille <akim@epita.fr>
11419 * src/lalr.c (matrix_print): New.
11420 (transpose): Use it.
11421 Use arrays instead of pointers.
11423 2001-12-05 Akim Demaille <akim@epita.fr>
11425 * src/lalr.c (maxrhs): Move to...
11426 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
11427 * src/lalr.c (build_relations): Adjust.
11429 2001-12-05 Akim Demaille <akim@epita.fr>
11431 * src/lalr.c (transpose): Free the memory allocated to the
11432 argument, as it is replaced by the results by the unique caller.
11433 (build_relations): Merely invoke transpose: it handles the memory
11434 deallocation.
11435 Improve variable locality.
11436 Avoid variables used as mere abbreviations.
11437 (compute_lookaheads): Use arrays instead of pointers.
11439 2001-12-05 Akim Demaille <akim@epita.fr>
11441 * src/lalr.c (initialize_F): Improve variable locality.
11442 Avoid variables used as mere abbreviations.
11444 2001-12-05 Akim Demaille <akim@epita.fr>
11446 * src/derives.c (print_derives): Display the ruleno.
11447 * src/lalr.c (initialize_F, transpose): Better variable locality
11448 to improve readability.
11449 Avoid variables used as mere abbreviations.
11451 2001-12-05 Akim Demaille <akim@epita.fr>
11453 * src/lalr.c (traverse): Use arrays instead of pointers.
11455 2001-12-05 Akim Demaille <akim@epita.fr>
11457 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11458 the handling of squeue.
11459 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11461 2001-12-05 Akim Demaille <akim@epita.fr>
11463 Because useless nonterminals are now kept alive (instead of being
11464 `destroyed'), we now sometimes examine them, and store information
11465 related to them. Hence we need to know their number, and adjust
11466 memory allocations.
11468 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11469 static.
11470 * src/LR0.c (allocate_itemsets): The memory allocated to
11471 `symbol_count' was used for two different purpose: once to count
11472 the number of occurrences of each symbol, and later reassigned to
11473 `shift_symbol', containing the symbol that can be shifted from a
11474 given state.
11475 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11476 only, and...
11477 (new_itemsets): Allocate `shift_symbol' here.
11478 (allocate_itemsets): symbol_count includes useless nonterminals.
11479 Make room for them.
11480 (free_storage): Use `free', not `XFREE', for pointers that cannot
11481 be null.
11483 2001-12-05 Akim Demaille <akim@epita.fr>
11485 * src/nullable.c (set_nullable): Deobfuscate the handling of
11486 ritem.
11487 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11489 2001-12-05 Akim Demaille <akim@epita.fr>
11491 * src/gram.c, src/gram.h (ritem_print): New.
11492 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
11493 (This useless function was defined only to work around VMS linkers
11494 that can't handle compilation units with variables only).
11495 * src/reduce.c (dump_grammar): Use it to trace the construction of
11496 ritem.
11498 2001-12-04 Paul Eggert <eggert@twinsun.com>
11500 * src/bison.simple (union yyalloc): Change member names
11501 to be the same as the stack names.
11502 (yyparse): yyptr is now union yyalloc *, not char *.
11503 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
11504 and may generate better code on some machines.
11505 (yystpcpy): Use prototype if __STDC__ is defined, not just
11506 if __cplusplus is defined.
11508 2001-11-30 Akim Demaille <akim@epita.fr>
11510 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
11511 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
11512 Gettext doesn't compile cleanly, and dies with -Werror.
11513 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
11514 Include WARNING_CFLAGS here.
11515 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

11523 (SIZE_MAX, UINT_MAX): New macros.
11524 (quotearg_n_options): Abort if N is negative.
11525 Avoid overflow check on hosts where size_t is 64 bits and int

11527 Fix off-by-one typo that caused unnecessary reallocation.
11529 2001-11-29 Paul Eggert <eggert@twinsun.com>
11531 Name space cleanup in generated parser.
11533 * doc/bison.texinfo (Bison Parser): Discuss system headers

11536 * src/bison.simple:
11537 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
11538 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
11539 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
11541 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
11542 on user names when possible.
11544 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
11545 Simplify test for whather <alloca.h> exists.
11547 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
11549 (<stdio.h>): Include if YYDEBUG.
11551 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
11552 ! defined (yyoverflow) && ! defined (yymemcpy).
11554 (yymemcpy, yyparse): Rename local variables as needed so that
11555 they all begin with 'yy'.
11557 (yystrlen, yystpcpy): New functions.
11559 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
11560 All uses changed.
11562 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
11563 instead of relying on string.h functions. Use YYSTACK_ALLOC
11564 and YYSTACK_FREE instead of malloc and free.
11566 2001-11-30 Akim Demaille <akim@epita.fr>
11568 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
11569 before their first uses.

11576 2001-11-30 Akim Demaille <akim@epita.fr>
11578 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
11579 if body instead of `;' to pacify GCC's warnings.
11581 2001-11-30 Akim Demaille <akim@epita.fr>
11583 Instead of mapping the LHS of unused rules to -1, keep the LHS
11584 valid, but flag the rules as invalid.
11586 * src/gram.h (rule_t): `useful' is a new member.
11587 * src/print.c (print_grammar): Adjust.
11588 * src/derives.c (set_derives): Likewise.
11589 * src/reader.c (packgram, reduce_output): Likewise.
11590 * src/reduce.c (reduce_grammar_tables): Likewise.
11591 * tests/reduce.at (Underivable Rules, Useless Rules): New.

11604 (reduce_output): Adjust.
11605 * tests/reduce.at (Useless Nonterminals): Adjust.
11607 2001-11-30 Akim Demaille <akim@epita.fr>

11619 New macros.
11620 (union yyalloc): New type.
11621 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
11622 an arbitrary restriction on hosts where size_t is wider than int.
11624 (yyparse): Don't dump core if alloca or malloc fails; instead, report
11625 a parser stack overflow. Allocate just one block of memory for all
11626 three stacks, instead of allocating three blocks; this typically is
11627 faster and reduces fragmentation.
11629 Do not limit the number of items in the stack to a value that fits
11630 in 'int', as this is an arbitrary limit on hosts with 64-bit
11631 size_t and 32-bit int.
11633 2001-11-29 Marc Autret <autret_m@epita.fr>
11635 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

11681 2001-11-28 Akim Demaille <akim@epita.fr>
11683 * src/closure.c (closure): `b' and `ruleno' denote the same value:
11684 keep ruleno only.
11686 2001-11-28 Akim Demaille <akim@epita.fr>
11688 * src/closure.c (closure): Instead of looping over word in array

11718 2001-11-27 Paul Eggert <eggert@twinsun.com>
11720 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

11963 (print_actions): Don't output the actions as part of the nodes,
11964 since that's the job of the edges.

12058 * tests/calc.at, tests/output.at, tests/regression.at,
12059 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

12089 arg is const.

13479 2001-01-18 Akim Demaille <akim@epita.fr>
13481 Since we now use obstacks, more % directives can be enabled.
13483 * src/lex.c (percent_table): Also accept `%yacc',
13484 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
13485 `%debug'.
13486 Handle the actions for `%semantic_parser' and `%pure_parser' here,
13487 instead of returning a token.
13488 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
13489 * src/reader.c (read_declarations): Adjust.
13490 * src/files.c (open_files): Don't call `compute_base_names', don't

13492 *in* the input file now.
13493 (output_files): Do it here.
13494 * src/output.c (output_headers): Document the fact that this patch
13495 introduces a guaranteed SEGV for semantic parsers.
13496 * doc/bison.texinfo: Document them.
13497 * tests/suite.at: Exercise these %options.
13499 2000-12-20 Akim Demaille <akim@epita.fr>

13504 (output_obstack): New.
13505 Adjust all dependencies.
13506 * src/conflicts.c: Return a string.

13511 2000-12-20 Akim Demaille <akim@epita.fr>
13513 * src/files.c (open_files): Fix the computation of short_base_name
13514 in the case of `-o foo.tab.c'.
13516 2000-12-20 Akim Demaille <akim@epita.fr>
13518 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

13520 FILE * parameters.
13522 2000-12-20 Akim Demaille <akim@epita.fr>
13524 * src/files.c (open_files): Actually the `.output' file is based
13525 on the short_base_name, not base_name.
13526 * tests/suite.at (Checking output file names): Adjust.
13528 2000-12-20 Akim Demaille <akim@epita.fr>
13530 * src/bison.s1: Remove, we now use directly...
13531 * src/bison.simple: this.

13545 vars.
13546 (open_files): Don't compute them.
13547 (output_files): Adjust.
13548 (base_name, short_base_name): Be global.
13549 Adjust dependencies.
13551 2000-12-19 Akim Demaille <akim@epita.fr>
13553 * src/files.c (strsuffix): New.
13554 (stringappend): Be just like strcat but allocate.

13564 (obstack_grow_string): this.
13565 * src/output.c (output_parser): Recognize `%% actions' instead of

13572 * src/output.c (output_parser): Compute the `#line' lines when
13573 there are.
13574 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
13575 Suggested by Hans Aberg.
13577 2000-12-19 Akim Demaille <akim@epita.fr>
13579 Let the handling of the skeleton files be local to the procedures
13580 that use it.
13582 * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
13583 longer static.
13584 (fparser, open_extra_files): Remove.
13585 (open_files, output_files): Don't take care of fparser.
13586 * src/files.h: Adjust.
13587 * src/output.c (output_parser): Open and close the file to the

13594 * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...
13595 * src/system.h (BISON_SIMPLE, BISON_HAIRY): ... to here.
13597 2000-12-19 Akim Demaille <akim@epita.fr>
13599 * src/files.c (open_files): Yipee! We no longer need all the code
13600 looking for `/tmp' since we have no tmp file.
13602 2000-12-19 Akim Demaille <akim@epita.fr>
13604 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

13616 2000-12-12 Akim Demaille <akim@epita.fr>

13631 * lib/obstack.h: Formatting changes.
13632 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
13633 prevents type checking.
13634 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
13635 cast the value to (void *): assigning a `foo *' to a `void *'
13636 variable is valid.
13637 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
13638 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
13639 append characters.
13641 2000-11-17 Akim Demaille <akim@epita.fr>
13643 * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename

13655 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
13656 macros.
13657 Use them to declare the variables which are global or local to
13658 `yyparse'.
13660 2000-11-17 Akim Demaille <akim@epita.fr>
13662 * acconfig.h: Remove, no longer used.
13664 2000-11-07 Akim Demaille <akim@epita.fr>
13666 * src: s/Copyright (C)/Copyright/g.
13668 2000-11-07 Akim Demaille <akim@epita.fr>
13670 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
13671 defining.
13672 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
13674 2000-11-07 Akim Demaille <akim@epita.fr>
13676 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
13677 Merge in a single CPP if/else.

13682 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
13683 argument `data' for consistency with the prototypes.
13684 Qualify it `const'.
13685 (obstack_copy, obstack_copy0): Rename the second argument as
13686 `address' for consistency. Qualify it `const'.
13687 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
13688 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
13689 `const' their input argument (`data' or `address').
13690 Adjust the corresponding macros to include `const' in casts.
13692 2000-11-03 Akim Demaille <akim@epita.fr>
13694 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
13695 s/PFILE1/BISON_HAIRY/.
13696 Adjust dependencies.
13698 2000-11-03 Akim Demaille <akim@epita.fr>
13700 For some reason, this was not applied.
13702 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
13703 `unlink': it's no longer used.
13705 2000-11-03 Akim Demaille <akim@epita.fr>
13707 * src/files.c (skeleton_find): New function, eved out of...
13708 (open_files, open_extra_files): here.
13710 2000-11-03 Akim Demaille <akim@epita.fr>
13712 Don't use `atexit'.
13714 * src/files.c (obstack_save): New function.
13715 (done): Rename as...
13716 (output_files): this.
13717 Use `obstack_save'.
13718 * src/main.c (main): Don't use `atexit' to register `done', since
13719 it no longer has to remove tmp files, just call `output_files'
13720 when there are no errors.
13722 2000-11-02 Akim Demaille <akim@epita.fr>
13724 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
13725 `unlink': it's no longer used.
13726 * src/files.h: Formatting changes.

13733 (defines_ostack, table_obstack): New.
13734 Adjust dependencies of the former into uses of the latter.
13735 * src/output.c (output_short_or_char_table, output_short_table):
13736 Convert to using obstacks.
13737 * src/reader.c (copy_comment2): Accept one FILE * and two
13738 obstacks.
13739 (output_token_defines, reader_output_yylsp): Use obstacks.

13755 Introduce obstacks.
13756 Change each use of `faction' into a use of `action_obstack'.
13758 * lib/obstack.h, lib/obstack.c: New files.
13759 * src/files.c (faction): Remove.
13760 (action_obstack): New.

13770 (output_short_table, output_token_translations): Use it.
13771 (goto_actions): Use output_short_table.
13773 2000-10-16 Akim Demaille <akim@epita.fr>
13775 * src/symtab.c (bucket_new): New function.
13776 (getsym): Use it.
13778 * src/output.c (output_short_table): New argument to display the
13779 comment associated with the table.
13780 Adjust dependencies.
13781 (output_gram): Use it.
13782 (output_rule_data): Nicer output layout for YYTNAME.
13784 2000-10-16 Akim Demaille <akim@epita.fr>
13786 * src/lex.c (read_typename): New function.
13787 (lex): Use it.
13788 * src/reader.c (copy_dollar): Likewise.
13790 2000-10-16 Akim Demaille <akim@epita.fr>
13792 * src/reader.c (copy_comment2): Expect the input stream to be on
13793 the `/' which is suspected to open a comment, instead of being
13794 called after `//' or `/*' was read.
13795 (copy_comment, copy_definition, parse_union_decl, copy_action)
13796 (copy_guard): Adjust.
13798 2000-10-16 Akim Demaille <akim@epita.fr>
13800 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

13805 * src/reader.c (copy_dollar): New function.
13806 (copy_guard, copy_action): Use it.
13808 2000-10-16 Akim Demaille <akim@epita.fr>
13810 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
13811 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
13812 New files, from Fileutils 4.0.27.
13813 * src/main.c (printable_version): Remove.
13814 * src/lex.c, src/reader.c: Use `quote'.
13816 2000-10-04 Akim Demaille <akim@epita.fr>
13818 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
13820 2000-10-04 Akim Demaille <akim@epita.fr>
13822 * doc/bison.texinfo: Various typos spotted by Neil Booth.
13824 2000-10-04 Akim Demaille <akim@epita.fr>
13826 When a literal string is used to define two different tokens,
13827 `bison -v' segfaults.
13828 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
13830 * tests/regression.m4: New file.
13831 Include the core of the sample provided by Piotr Gackiewicz.
13832 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
13833 properly.
13835 2000-10-04 Akim Demaille <akim@epita.fr>
13837 * src/reader.c (parse_expect_decl): Keep `count' within the size
13838 of `buffer'.
13839 From Neil Booth.
13841 2000-10-02 Paul Eggert <eggert@twinsun.com>
13843 * bison.s1 (yyparse): Assign the default value
13844 unconditionally, to avoid a GCC warning and make the parser a
13845 tad smaller.
13847 2000-10-02 Akim Demaille <akim@epita.fr>
13849 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
13850 options.
13852 2000-10-02 Akim Demaille <akim@epita.fr>
13854 * src/derives.c, src/print.c, src/reduce.c: To ease the
13855 translation, move some `\n' out of the translated strings.
13857 2000-10-02 Akim Demaille <akim@epita.fr>
13859 The location tracking mechanism is precious for parse error
13860 messages. Nevertheless, it is enabled only when `@n' is used in
13861 the grammar, which is a different issue (you can use it in error
13862 message, but not in the grammar per se). Therefore, there should
13863 be another means to enable it.
13865 * src/getargs.c (getargs): Support `--locations'.
13866 (usage): Report it.
13867 * src/getargs.h (locationsflag): Export it.
13868 * src/lex.c (percent_table): Support `%locations'.
13869 * src/reader.c (yylsp_needed): Remove this variable, now replaced
13870 with `locationsflag'.
13871 * doc/bison.texinfo: Document `--locations' and `%locations'.
13872 Sort the options.
13873 * tests/calc.m4: Test it.
13875 For regularity of the names, replace each
13876 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
13877 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
13878 In addition replace each `flag' with `_flag'.
13880 2000-10-02 Akim Demaille <akim@epita.fr>
13882 Also test parse error messages, including with YYERROR_VERBOSE.
13884 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
13885 associative).
13886 Use it to check the computations.
13887 Use it to check `nonassoc' is honored.
13888 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
13889 `--yyerror-verbose'.
13890 (_AT_CHECK_CALC): Adjust to this option.
13891 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
13893 2000-10-02 Akim Demaille <akim@epita.fr>
13895 Test also `--verbose', `--defines' and `--name-prefix'. Testing
13896 the latter demonstrates a flaw in the handling of non debugging
13897 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
13898 was used in order to simplify:
13900 #if YYDEBUG
13901 if (yydebug)
13902 {
13903 ...
13904 }
13905 #endif
13907 into
13909 if (yydebug)
13910 {
13911 ...
13912 }
13914 unfortunately this leads to a CPP conflict when
13915 `--name-prefix=foo' is used since it produces `#define yydebug
13916 foodebug'.
13918 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
13919 (YYDPRINTF): New macro.
13920 Spread its use.
13921 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
13922 the bison options.
13923 Also test `--verbose', `--defines' and `--name-prefix'.
13925 2000-10-02 Akim Demaille <akim@epita.fr>
13927 Improve the readability of the produced parsers.
13929 * src/bison.s1: Formatting changes.
13930 Improve the comment related to the `$' mark.
13931 (yydefault): Don't fall through to `yyresume': `goto' there.
13932 * src/output.c (output_parser): When the `$' is met, skip the end
13933 of its line.
13934 New variable, `number_of_dollar_signs', to check there's exactly
13935 one `$' in the parser skeleton.
13937 2000-10-02 Akim Demaille <akim@epita.fr>
13939 * lib/xstrdup.c: New file, from the fileutils.
13940 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
13941 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
13942 instead of strlen + xmalloc + strcpy.
13943 * src/symtab.c (copys): Remove, use xstrdup instead.
13945 2000-10-02 Akim Demaille <akim@epita.fr>
13947 * src/gram.h (associativity): New enum type which replaces the
13948 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
13949 `right_assoc', `left_assoc' and `non_assoc'.
13950 Adjust all dependencies.
13951 * src/reader.c: Formatting changes.
13952 (LTYPESTR): Don't define it, use it as a literal in
13953 `reader_output_yylsp'.
13954 * src/symtab.h (symbol_class): New enum type which replaces the
13955 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
13956 `sunknown', `stoken and `snterm'.
13958 2000-10-02 Akim Demaille <akim@epita.fr>
13960 * src/getargs.c (fixed_outfiles): Rename as...
13961 (yaccflag): for consistency and accuracy.
13962 Adjust dependencies.
13964 2000-10-02 Akim Demaille <akim@epita.fr>
13966 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
13967 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
13968 difficult and introduced a lot of core dump. It turns out that
13969 Bison used an implementation of `xmalloc' based on `calloc', and
13970 at various places it does depend upon the initialization to 0. I
13971 have not tried to isolate the pertinent places, and all the former
13972 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
13973 someone should address this issue.
13975 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
13976 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

14076 `user_toknums' is output as a `short[]' in `output.c', while it is
14077 defined as a `int[]' in `reader.c'. For consistency with the
14078 other output tables, `user_toknums' is now defined as a table of

14098 from output.c.

14121 Don't define PARAMS.
14122 * src/system.h: Define PARAMS.

14124 purpose of config.h. system.h must not try to fix wrong
14125 definitions in config.h.
14127 2000-09-20 Akim Demaille <akim@epita.fr>
14129 * src/derives.h: New file.

14251 complain.c::complain.
14252 (toomany): Remove, use fatal instead.
14253 * src/files.c (done): No argument, use complain_message_count.
14254 * src/main.c (main): Register `done' to `atexit'.

14343 Change the handling of @s so that they behave exactly like $s.
14344 There is now a pseudo variable @$ (readble and writable), location
14345 of the lhs of the rule (by default ranging from the location of
14346 the first symbol of the rhs, to the location of the last symbol,
14347 or, if the rhs is empty, YYLLOC).
14349 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
14350 yyval.
14351 (yyparse): When providing a default semantic action, provide a

14354 same way you stack YYVAL.
14355 * src/reader.c (read_declarations): Use warns.
14356 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

14382 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
14383 One `#if YYDEBUG' remains, since it uses variables which are
14384 defined only if `YYDEBUG != 0'.
14386 2000-03-16 Akim Demaille <akim@epita.fr>
14388 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

15056 New function.
15057 (readgram): Use `#if 0' around code that accepted %command
15058 inside grammar rules: The documentation doesn't allow it,
15059 and it will fail since the %command processors scan for the next %.
15060 (parse_token_decl): Extended the %token
15061 declaration to allow a multi-character symbol as an alias.
15062 (parse_thong_decl): New function.
15063 (read_declarations): Added %thong declarations.
15064 (read_declarations): Handle NOOP to deal with allowing
15065 % declarations as another means to specify the flags.
15066 (readgram): Allow %prec prior to semantics embedded in a rule.
15067 (skip_to_char, read_declarations, copy_definition)
15068 (parse_token_decl, parse_start_decl, parse_type_decl)
15069 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
15070 (get_type_name, copy_guard, copy_action, readgram)
15071 (get_type, packsymbols): Revised most error messages.
15072 Changed `fatal' to `warnxxx' to avoid aborting for error.
15073 Revised and use multiple warnxxx functions to avoid using VARARGS1.
15074 (read_declarations): Improve the error message for
15075 an invalid character. Do not abort.
15076 (read_declarations, copy_guard, copy_action): Use
15077 printable_version to avoid unprintable characters in printed output.
15078 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
15079 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
15080 Allow the type of a non-terminal can be given
15081 more than once, as long as all specifications give the same type.
15083 * src/output.c:
15084 (output_headers, output_trailers, output, output_gram)
15085 (output_rule_data): Implement noparserflag variable.
15086 Implement toknumflag variable.
15087 (output): Call reader_output_yylsp to output LTYPESTR.
15089 * src/main.c (main):
15090 If reader sees an error, don't process the grammar.
15091 (fatals): Updated to not use VARARGS1.
15092 (printable_version, int_to_string, warn, warni, warns, warnss)
15093 (warnsss): New error reporting functions. Avoid abort for error.
15095 * src/lex.h:
15096 Added THONG and NOOP for alias processing.
15097 Added SETOPT for the new code that allows setting options with %flags.
15099 * src/lex.c:
15100 Include getopt.h. Add some extern decls.
15101 (safegetc): New function to deal with EOF gracefully.
15102 (literalchar); new function to deal with reading \ escapes.
15103 (lex): Use literalchar.
15104 (lex): Implemented "..." tokens.
15105 (literalchar, lex, parse_percent_token): Made tokenbuffer
15106 always contain the token. This includes growing the token
15107 buffer while reading an integer.
15108 (parse_percent_token): Replaced if-else statement with percent_table.
15109 (parse_percent_token): Added % declarations as another
15110 way to specify the flags -n, -l, and -r. Also added hooks for
15111 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
15112 major changes to files.c.
15113 (lex) Retain in the incoming stream a character following
15114 an incorrect '/'.
15115 (skip_white_space, lex): Revised most error messages
15116 and changed fatal to warn to avoid aborting.
15117 (percent_table): Added %thong declarations.
15119 * src/gram.h: Comment changes.
15121 * src/files.c (openfiles, open_extra_files, done):
15122 Add faction flag
15123 and actfile file. Handle noparserflag. Both for -n switch.
15125 * src/conflicts.c (resolve_sr_conflict):
15126 Remove use of alloca.
