7 * src/output.h, src/output.c (error_verbose): Move to...
8 * src/getargs.h, src/getargs.c: here.
12 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
14 * data/c.m4 (b4_copyright): Put the special exception for Bison
15 skeletons here, so we don't have to put it in each skeleton. All
16 uses changed. Suggested by Akim Demaille. Also, wrap the
17 copyright notice, in case it is longer than 80 columns. Replace
18 comma by newline after title.
20 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
22 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
23 incompatibility, not a bug. Mention that it wasn't fixed as of
26 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
28 * examples/extexi: Enforce the precedence of concatenation over
30 Reported by Tommy Nordgren.
32 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
34 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
35 with the member "token".
36 Reported by Martin Nylin.
38 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
40 * data/glr.c: Switch to Bison 2.2 special-exception language in
41 the copyright notice. Use more-regular format for titles and

49 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
51 * data/glr.cc: Remove dead code.
53 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
55 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
56 that variable and the line breaks the bootstrap. Problem reported
59 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
61 * doc/bison.texinfo (Multiple start-symbols): New.
63 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
65 * etc/README, etc/bench.pl: New.
67 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
69 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
71 Reported by Mickael Labau.

74 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
76 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
77 Problem reported by Bob Rossi.
79 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
81 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
82 and didn't really work.
83 For the index, use @ifnotinfo, not @iftex.
84 Minor cleanups of spacing and terminology.
86 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
88 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
89 of AT_NAME_PREFIX when %name-prefix is not used.
91 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
93 Apply --prefix to C++ skeletons too: they change the namespace.
94 The test suite already exercize these cases.
95 * data/c++.m4 (b4_namespace): New.
96 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
97 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
98 * data/yacc.c, data/glr.c: Remove a useless `[]'.
99 * doc/bison.texinfo: Document it.
100 (Option Cross Key): Use @multitable in all formats. It looks
101 nicer, even in TeX outputs.
102 (Rules): Use the same code whatever the output type is.
103 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
104 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
105 * tests/calc.at: Use it, instead of hard coding `yy'.

115 * doc/Makefile.am (EXTRA_DIST): Adjust.
117 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
119 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
121 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
122 * doc/bison.texinfo (Calc++ Scanner): Use it.
124 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
126 Fix two nits reported by twlevo, plus one more that I discovered.
128 * src/assoc.h (assoc_to_string): Give a name to the arg, as
129 this is the usual Bison style.
130 * src/location.h (location_print): Likewise.
132 * src/reader.h (token_name): Likewise.
134 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
136 Fix some nits reported by twlevo.
137 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
138 and "POSIX". Use more-modern syntax for URLs. Mention C++
139 and ask for Java. Don't hardwire OS version numbers. Add
141 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
142 * src/conflicts.c (solved_conflicts_obstack): Now static.
144 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
146 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
147 page. Say "you can use it" not "you may use it" as on the web page;
148 we're describing capabilities not granting permission.
150 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
152 * data/glr.c (yyresolveLocations): Rename local variables to avoid
153 shadowing warnings. Use usual patter for iterating through RHS.
154 * tests/glr-regression.at
155 (Uninitialized location when reporting ambiguity):
156 Modify yylex so that it uses its argument, rather than trying
157 to rely on ARGSUSED (which doesn't work for gcc with warnings).
158 const char -> char const.
160 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
161 Don't use tabs inside commands; it messes up 'ps'.
162 Problem reported by twlevo.
164 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
166 * tests/glr-regression.at (Uninitialized location when reporting
167 ambiguity): New test case.
168 * data/glr.c (yyresolveLocations): New function, which uses
170 (yyresolveValue): Invoke yyresolveLocations before reporting an
172 * doc/bison.texinfo (Default Action for Locations): Note
173 YYLLOC_DEFAULT's usage for ambiguity locations.
174 (GLR Semantic Actions): Cross-reference those notes.
176 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
178 * tests/glr-regression.at (Leaked semantic values when reporting
179 ambiguity): Remove unnecessary union and type declarations.
180 (Leaked lookahead after nondeterministic parse syntax error): New test
182 * data/glr.c (yyparse): Check for zero stacks remaining before
183 attempting to shift the lookahead so that you don't lose it.
185 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
187 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
188 * tests/glr-regression.at (Leaked semantic values when reporting
189 ambiguity): New test case.
190 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
191 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
192 now unnecessary yystackp parameter.
193 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
194 destructors can be called.
196 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
197 in existing testcases.
199 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
201 Don't leak semantic values for parent RHS when a user action cuts the
202 parser, and clean up related code a bit.
203 * tests/glr-regression.at (Leaked merged semantic value if user action
204 cuts parse): Rename to...
205 (Leaked semantic values if user action cuts parse): ... this. Add check
206 for leaked parent RHS values.
207 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
208 between an unresolved state (non-empty chain of semantic options) and
209 an incomplete one (signaled by an empty chain).
210 (yyresolveStates): Document the interface. Move all manipulation of a
211 successfully or unsuccessfully resolved yyGLRState to...
212 (yyresolveValue): ... here so that yyresolveValue always leaves a
213 yyGLRState with consistent data and thus is easier to understand.
214 Remove the yyvalp and yylocp parameters since they are always just
215 taken from the yys parameter. When reporting a discarded merged value
216 in debugging output, note that it is incompletely merged. Document the
218 (yyresolveAction): If resolving any of the RHS states fails, destroy
219 them all rather than leaking them. Thus, as long as user actions are
220 written to clean up the RHS correctly, yyresolveAction always cleans up
221 the RHS of a semantic option. Document the interface.
223 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
225 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
226 led to a segmentation fault in GNU Pascal. Problem reported
229 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
231 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
232 mid-rule action inside a nonterminal symbol in order to declare a
233 destructor for its semantic value.

239 __cplusplus && ! defined _STDLIB_H && !
240 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
241 defined free))]: Include <stdlib.h> rather than rolling our own
242 declarations of malloc and free, to avoid problems with
243 incompatible declarations (using 'throw') C++'s stdlib.h. This
244 should fix Debian bug 340012

256 * NEWS: Version 2.1a.
257 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
258 since C99 requires this.
260 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
262 * m4/c-working.m4: New file.
263 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.

267 * Makefile.maint: Merge from coreutils.
269 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
271 More portability fixes for problems summarized by Nelson H. F. Beebe.
273 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
274 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
275 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
276 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

282 More portability fixes for problems summarized by Nelson H. F. Beebe.
284 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
285 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
287 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
288 nodist_PROGRAMS, since we don't need to actually compile the
289 example if we're just doing a plain 'make'. This avoids bothering
290 the installer unnecessarily about problems due to weird C++

295 More portability fixes for problems summarized by Nelson H. F. Beebe.
297 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
298 than #include "...", and compile with -I'.'. The old method was
299 not portable, according to Posix and the C standard, and it does
300 not work with Sun C 5.7, where previous #line directives affect
301 the working directory used in later #include "..." directives.

320 that '#include <string>' works.
322 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
323 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
324 "warning: sorry: semantics of inline function static data `const
325 unsigned char translate_table[262]' are wrong (you'll wind up with

329 or, xor to not_, and_, or_, and xor_, respectively. This works
330 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
331 random system header somewhere that includes the equivalent of

338 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
340 During deterministic GLR operation, user actions should be able to
341 influence the parse by changing yychar. To make this easier to fix and
342 to make glr.c easier to evolve in general, don't maintain yytoken in
343 parallel with yychar; just compute yytoken when needed.
344 * tests/glr-regression.at (Incorrect lookahead during deterministic
345 GLR): Check that setting yychar in a user action has the intended

348 (yyclearin): Don't set *yytokenp.
349 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
350 yychar rather than *yytokenp to determine the current lookahead.
351 Compute yytoken locally when needed.
352 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
355 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
356 after `--report' documentation.

370 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
371 got from <http://bro-ids.org/download.html>. The bug is that
372 when two actions appeared in succession, the second one was
373 scanned before the first one was added to the grammar rule
374 as a midrule action. Bison then output the incorrect warning
375 "parse.y:905.17-906.36: warning: unused value: $3".
376 * src/parse-gram.y (BRACED_CODE, action): These are no longer
377 associated with a value.
378 (rhs): Don't invoke grammar_current_rule_action_append.
379 (action): Invoke it here instead.
380 * src/reader.c (grammar_midrule_action): Now extern.
381 (grammar_current_rule_action_append): Don't invoke
382 grammar_midrule_action; that is now the scanner's job.
383 * src/reader.h (last_string, last_braced_code_loc):
384 (grammar_midrule_action): New decls.
385 * src/scan-gram.l (last_string): Now extern, sigh.
386 (last_braced_code_loc): New extern variable.
387 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
388 rule already has an action.
389 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
390 * tests/input.at (AT_CHECK_UNUSED_VALUES):
391 Add some tests to check that the above changes fixed the bug.
393 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
395 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
396 All used changed. Check whether the symbol has a destructor,
397 not whether it is typed.
398 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
399 that the values are still reported as unused. All line numbers

416 user can override the types.

424 * tests/regression.at (Web2c Actions): Adjust to above changes.
426 * src/reader.c (check_and_convert_grammar): New function.
427 (reader): Close the input file even if something went wrong during
428 parsing. Minor file descriptor leak reported by twlevo.

636 (Special Features for Use in Actions): Add YYEOF entry and mention it
638 In the yychar entry, remove mention of the local yychar case (pure
639 parser) since this is irrelevant information when writing semantic
640 actions and since it's already discussed in `Bison Symbols' where
641 yychar is otherwise described as an external variable.
642 In the yychar entry, don't call it the `current' look-ahead since it
643 isn't when semantic actions are deferred.

646 Add yylloc and yylval entries discussing look-ahead usage.
647 (Look-Ahead Tokens): When discussing yychar, don't call it the

702 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
704 * data/glr.c (yyresolveValue): When merging semantic options, if at
705 least one user action succeeds but a later one cuts the parse, then
706 destroy the semantic value before returning rather than leaking it.
707 (yyresolveStates): If a user action cuts the parse and thus
708 yyresolveValue fails, ignore the (unset) semantic value rather than
709 corrupting the yyGLRState, and empty the semantic options list since
710 the user actions should have called all necessary destructors.
711 Simplify code with YYCHK.
712 * tests/glr-regression.at (Corrupted semantic options if user action
713 cuts parse): New test case.
714 (Undesirable destructors if user action cuts parse): New test case.

1012 sed out the final state number.
1014 Work around portability problem on Solaris 10: flex-generated
1015 files include <stdio.h> before <config.h>, which messes up
1016 because the latter defines __EXTENSIONS__. Address the problem
1017 by creating two new little files that include <config.h> first,
1018 then include the flex-generated files. Rewrite everyone else
1019 to include <config.h> first, as well.
1020 * lib/timevar.c: Always include "config.h".

1066 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
1067 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
1068 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code

1096 it's no longer just a file.
1097 * data/glr.c: Grant a special exception for C GLR parsers, that
1098 reads like the already-existing exception for C LALR(1) parsers.

1100 * data/lalr1.cc: Likewise.
1101 * data/location.cc: Likewise.

1115 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
1116 We can revert this once things settle down.
1118 * src/conflicts.c (conflicts_print): Don't print file name twice
1119 when %expect fails because there were no conflicts.

1359 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
1361 Undo the parts of the unlocked-I/O change that substituted
1362 putc or puts for printf. This might hurt performance a bit,
1363 but some people prefer the printf style.

1394 Use unlocked I/O for a minor performance improvement on hosts like
1395 GNU/Linux and Solaris that support unlocked I/O. The basic idea
1396 is to use the gnlib unlocked-io module, and to prefer putc and
1397 puts to printf when either will work (since the latter doesn't
1398 come in an unlocked flavor).

1492 2005-10-02 Akim Demaille <akim@epita.fr>
1494 * data/location.cc: New, extract from...
1495 * data/lalr1.cc: here.
1496 (location.hh): Include it after the user prologue, in case the
1497 filename type is defined by the user.
1498 Forward declation location and position before the pre-prologue.
1499 (yyresult_): Rename as...
1500 (yyresult): this, it's a local variable, not an attribute.
1501 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
1503 2005-10-01 Akim Demaille <akim@epita.fr>
1505 * examples/extexi: Restore the #line generation.

1512 (parser::token): New, from the moved free definition of tokens.
1513 (parser::semantic_value): Now a full definition instead of an
1514 indirection to YYSTYPE.
1515 (b4_post_prologue): No longer included in the header file, but
1516 in the implementation file.
1517 * doc/bison.texi (C+ Language Interface): Update.
1518 * src/parse-gram.y: Support unary %define.
1519 * tests/actions.at: Define global_tokens_and_yystype for backward
1520 compatibility until we update the tests.
1521 * tests/calc.at: Idem.
1522 (first_line, first_column, last_line, last_column): Define for lalr1.cc
1523 to simplify the code.
1525 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
1527 Port to SunOS 4.1.4, which lacks strtoul and strerror.
1528 Ah, the good old days! Problem reported by Peter Klein.
1529 * bootstrap (gnulib_modules): Add strerror, strtoul.
1530 * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
1531 * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.
1533 2005-09-29 Akim Demaille <akim@epita.fr>

1537 (YYERROR_VERBOSE_IF): Remove.
1538 (yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
1539 parser members, replaced by...
1540 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
1542 (yysyntax_error_): Takes the state number as argument.
1543 (yyreduce_print_): Use the argument yyrule, not the former
1546 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
1548 * bootstrap (gnulib_modules): Add verify.
1549 * lib/.cvsignore: Add verify.h.

1555 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
1557 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
1558 local variables whose names begin with 'yy'.
1559 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1560 Trivial changes from Joel E. Denny.
1562 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1564 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1565 don't use alloca any more.
1567 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1568 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
1569 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
1570 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
1571 to match yacc.c, to test more hosts.
1573 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
1575 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
1576 doesn't affect behavior.
1577 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
1579 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
1580 This works a bit better with glibc, if user code has already included
1582 * doc/bison.texinfo (Bison Parser): Document that users can't
1583 arbitrarily use malloc and free for other purposes. Document
1584 that <alloca.h> and <malloc.h> might be included.
1585 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
1586 user must declare alloca.

1595 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
1597 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
1598 (YYSTACK_ALLOC_MAXIMUM): Use it.
1599 (yysyntax_error): New function.
1600 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
1601 multiple syntax errors are reported, and alloca is being used.
1602 Instead, reallocate buffers twice as big each time, so that
1603 we waste at most half the allocated memory. Start with a small
1604 (128-byte) buffer that will suffice in most cases anyway.
1605 Use yysyntax_error to do most of the work.
1607 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1608 yynerrs is the number of errors reported, not the number of
1611 * tests/glr-regression.at (Duplicated user destructor for lookahead):
1612 Mark it as expected to fail.
1613 Cast result of malloc; problem reported by twlevo@xs4all.nl.
1614 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
1615 Don't start user-code symbols with "yy", to avoid name space problems.
1617 2005-09-19 Akim Demaille <akim@epita.fr>
1619 Remove the traits, failed experiment.
1620 It never proved useful, and anyway because of the current
1621 definition, it was not possible to have several specialization of
1622 this traits, making it useless.
1623 * data/lalr1.cc (yy:traits): Remove.
1624 Inline its definitions in the parser class.
1626 2005-09-19 Akim Demaille <akim@epita.fr>

1649 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
1650 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
1651 is not defined. This is an awful hack, but it's enough for now.
1652 All callers changed.
1653 * tests/glr-regression-at (make_value): Args are const pointers now,
1654 to avoid GCC warning.
1655 (Duplicated user destructor for lookahead): New test. Currently
1656 skipped. It fails on my host but I'm not sure it'll always fail.
1658 2005-09-16 Akim Demaille <akim@epita.fr>
1660 * src/symtab.h (struct symbol): Declare the printer and destructor
1661 as const, to avoid accidental calls to free.
1662 (symbol_destructor_set, symbol_printer_set): Adjust.
1663 * src/symtab.c: Adjust.
1665 2005-09-16 Akim Demaille <akim@epita.fr>
1667 * data/c.m4 (b4_token_enums): New.
1668 (b4_token_defines): Rename as...
1669 (b4_token_enums_defines): this.
1670 (b4_token_defines): New, output only the #defines.
1671 * data/yacc.c, data/glr.c: Adjust.
1672 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
1673 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
1676 2005-09-16 Akim Demaille <akim@epita.fr>
1678 * data/lalr1.cc (yylex_): Remove, inline its code.
1679 (yyreport_syntax_error_): Remove, replaced by...
1680 (yysyntax_error_): this which returns a string and leaves to the
1681 caller the call to the users' error function.
1682 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
1683 Move from members of the parser object...
1684 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
1685 to local variables of the parse function.
1687 2005-09-16 Akim Demaille <akim@epita.fr>
1689 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
1690 since it's in Bison's name space.
1692 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
1694 * data/glr.c (yyresolveValue): Add default case to pacify
1695 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
1697 * NEWS: Document when yyparse started to return 2.
1698 * doc/bison.texinfo (Parser Function): Document when yyparse
1701 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
1702 (b4_filename_type): Renamed back from b4_file_name_type. All uses
1704 (class position): file_name -> filename (reverting). All uses changed.
1706 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
1708 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1709 do anything if $@ exists. This reverts part of the 2005-07-07
1712 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1714 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1715 contains obsolete information and isn't worth distributing as a
1716 separate file anyway.
1717 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1718 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
1719 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
1720 (yyparse): Abort if user code uses longjmp to throw an unexpected
1723 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
1725 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
1726 Suggested by twlevo@xs4all.nl.
1728 * data/glr.c (YYCHK1): Do not assume YYE is in range.
1729 This avoids a diagnostic from gcc -Wswitch-enum.
1730 Problem reported by twlevo@xs4all.nl.
1732 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1733 standards. Use "file name" or "file" or "name", depending on
1735 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1736 not to hack/foo.tab.c.
1737 (Calc++ Top Level): 2nd arg of main is not const.
1738 * data/glr.c: b4_filename -> b4_file_name.
1739 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

1756 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
1758 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
1761 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1763 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
1764 All uses changed. Invoke user destructor after an error during a
1765 split parse (trivial change from Joel E. Denny).
1767 * tests/glr-regression.at
1768 (User destructor after an error during a split parse): New test case.
1769 Problem reported by Joel E. Denny in:
1770 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
1772 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1774 * README-cvs: Give URLs for recommended tools.
1775 Mention Gzip version problem, and bootstrapping issues.
1776 Remove troubleshooting section, as it's somewhat obsolete.
1778 * bootstrap (no_cache): New var, to accommodate different wget
1779 variants. Use it instead of '-C off'. Problem reported by
1782 * data/glr.c (yydestroyStackItem): New function.
1783 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
1784 debugging information. Problem reported by Joel E. Denny.
1786 2005-08-25 Akim Demaille <akim@epita.fr>
1788 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
1790 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

1793 Don't invoke destructor on unresolved entries.
1794 * tests/glr-regression.at
1795 (User destructor for unresolved GLR semantic value): New test case.
1796 Problem reported by Joel E. Denny in:
1797 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
1799 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
1801 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
1803 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
1804 lib-prefix.m4, po.m4.
1806 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
1807 in yydestruct diagnostic, since it might not be an error.
1808 Problem reported by Joel Denny near end of
1809 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1810 * data/lalr1.cc (yyerturn): Likewise.
1811 * data/yacc.c (yyreturn): Likewise.
1812 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
1814 * src/files.c: Remove obsolete FIXME comment.
1816 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
1817 with the other templates, and to fix bogus run-on messages such
1818 as the one reported at the end of
1819 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1820 All callers changed to avoid the newline.
1821 (yyprocessOneStack): Output two lines rather than one, to accommodate
1822 the above change. This changes the debug output format slightly.
1824 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
1825 reported by Joel E. Denny in
1826 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
1828 * tests/glr-regression.at (Duplicate representation of merged trees):
1829 New test, from Joel E. Denny in:
1830 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.

1833 * configure.ac (AC_INIT): Bump to 2.0c.
1835 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
1837 * NEWS: Version 2.0b.
1839 * Makefile.am (SUBDIRS): Put examples before tests, so that
1840 "make check" doesn't finish with "All 1 tests passed".
1842 * tests/regression.at (Token definitions): Don't rely on
1843 AT_PARSER_CHECK for data that contains backslashes. It currently
1844 uses 'echo', and 'echo' isn't portable if its argument contains
1845 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1846 that the byte '\0xff' is not printable in the C locale; it is,
1847 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1848 not printable, so use '\0x81' to test.
1850 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1851 version of GCC, since the macro is used with non-GCC compilers.
1853 Fix core dump reported by Pablo De Napoli in
1854 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1855 * tests/regression.at (Invalid inputs with {}): New test.
1856 * src/parse-gram.y (token_name): Translate type before using
1859 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1860 the user's name space. All uses changed to __attribute__
1862 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1863 Add __attribute__ ((__noreturn__)).
1865 * etc/clcommit: Remove. We weren't using it, and it failed
1866 "make maintainer-distcheck".
1867 * Makefile.maint: Merge from coreutils.
1868 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1869 (syntax-check-rules): Change list of rules as described below.
1870 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

1880 Use grep -n, to make it easier to find violations.
1881 Use CVS_LIST and CVS_LIST_EXCEPT.
1882 (header_regexp, h_re): Remove.
1884 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
1885 (my-distcheck): Use more-modern GCC flags.
1886 (signatures, %.asc): Remove.
1887 (rel-files, announcement): Remove signatures.
1888 Restore old updating code, even though we don't use it, so
1889 that we're the same as coreutils.
1890 (alpha, beta, major): Depend on news-date-check.
1891 Make the upload commands.
1893 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

1900 * tests/sets.at: Likewise.
1902 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
1903 we comment out the Autoconf version number.
1904 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
1905 it's error-prone and "make maintainer-distcheck" rejects it.
1907 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
1908 Indent calls to "error" to pacify "make maintainer-distcheck",
1909 when the calls are not intended to be translated.
1910 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
1912 * src/Makefile.am (DEFS): Use +=, to pacify
1913 "make maintainer-distcheck".
1914 (bison_SOURCES): Add scan-skel.h.
1915 (sc_tight_scope): New rule, from coreutils.
1917 * src/files.c (src_extension, header_extension):
1918 Now static, not extern.
1919 * src/getargs.c (short_options): Likewise.
1920 * src/muscle_tab.c (muscle_table): Likewise.
1921 * src/parse-gram.y (current_class, current_type, current_prec):
1923 * src/reader.c (grammar_end, previous_rule_end): Likewise.
1924 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
1925 * src/main.c (main): Cast bindtextdomain and textdomain calls to
1926 void, to avoid warning when NLS is disabled.
1927 * src/output.c: Include scan-skel.h.
1928 (scan_skel): Remove decl, since scan-skel.h does this.
1930 Indent calls to "error" to pacify "make maintainer-distcheck".
1931 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
1932 * src/reader.h (gram_end, gram_lineno): New decls to pacify
1933 "make maintainer-distcheck".
1934 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
1935 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
1936 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
1937 (skel_lex_destroy, scan_skel): Move these decls to...
1938 * src/scan-skel.h: New file.
1939 * src/uniqstr.c (uniqstr_assert):
1940 Indent calls to "error" to pacify "make maintainer-distcheck".
1942 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
1945 * tests/torture.at: Revamp to avoid misuse of atoi that
1946 "make maintainer-distcheck" complained about.
1948 * examples/extexi (message): Don't print a message more than once,
1949 and omit line-number decoration that makes Emacs compile think
1950 that informative messages are worth worrying about.
1952 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
1954 * configure.ac: Update version number.
1956 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
1958 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
1959 autogenerated by the maintainer.
1960 * examples/calc++/.cvsignore: Add *.yy.
1962 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
1963 * lib/bitset_stats.c (bitset_stats_init): Likewise.
1964 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1966 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
1968 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
1969 from maintainer-distcheck about casting the argument of 'free'.
1971 * NEWS: Mention recent yytname changes.
1972 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
1974 * bootstrap: For translations that have not yet been upgraded to
1975 the new runtime-po domain, prime the pump by extracting the
1976 relevant strings from the obsolete translations. This code can be
1977 removed once the bison-runtime domain has been translated by each
1980 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
1981 now that token names are already quoted.
1983 Fix problem reported by Anthony Heading.
1984 * data/glr.c (YYTOKEN_TABLE): New macro.
1985 (yytname): Define if YYTOKEN_TABLE.
1986 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
1987 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
1988 (YYERROR_VERBOSE): Define the same way the other skeletons do.
1989 * src/output.c (prepare_symbols): Output token_table_flag.
1991 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
1993 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
1994 again if the first call fails.
1996 * data/glr.c (yytnamerr): New function.
1997 (yyreportSyntaxError): Use it to dequote most string literals.
1998 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
1999 with other skeletons. All uses changed.
2000 (yytnameerr_): New function.
2001 (yyreport_syntax_error): Use it to dequote most string literals.
2002 * data/yacc.c (yytnamerr): New function.
2003 (yyerrlab): Use it to decode most string literals.
2004 * doc/bison.texinfo (Decl Summary, Calling Convention):
2005 Clarify quoting convention of yytname.
2006 * src/output.c (prepare_symbols): Quote all names. This undoes
2007 the 2005-04-17 change, which is now accomplished (mostly) via
2008 changes in the parsers as described above.
2009 * tests/regression.at (Token definitions, Web2c Actions):
2010 Undo most 2005-04-17 change here, too.
2012 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
2014 Fix more problems reported by twlevo@xs4all.nl.
2015 * tests/cxx-type.at: Don't pipe output of ./types through sed to
2016 remove trailing spaces. This loses the exit status of ./types,
2017 and isn't needed since ./types shouldn't be emitting trailing
2019 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
2020 as the stack isn't valid in that case.
2022 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
2023 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
2024 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
2025 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
2027 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
2028 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
2029 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
2032 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
2033 overly-picky compilers that reject 'char *foo = "bar";'.
2035 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
2036 to FILE * parameter, not to stderr. This fixes a typo introduced
2037 in the 2005-07-12 change.
2039 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
2040 warnings from GCC 4.
2042 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
2043 (yyglrShiftDefer, yysplitStack):
2044 Remove unused parameters b4_pure_formals. All uses changed.
2045 (yyglrShift): Remove unused parameters b4_user_formals.
2047 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
2049 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
2051 Destructor cleanups and regularization among the three skeletons.
2052 * NEWS: Document the behavior changes.
2053 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
2054 stack before failing, as the cleanup code will do it for us now.
2055 * data/lalr1.cc (yyerrlab): Likewise.
2056 * data/glr.c (yyparse): Pop everything off the stack before
2057 freeing it, so that destructors get called properly.
2058 * data/lalr1.cc (yyreturn): Likewise.
2059 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
2060 This is more consistent.
2061 * doc/bison.texinfo (Destructor Decl): Mention more reasons
2062 why destructors might be called. 1.875 -> 2.1.
2063 (Destructor Decl, Decl Summary, Table of Symbols):
2064 Some English-language cleanups for %destructor.
2065 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
2066 Add output line for destructor of start symbol.
2067 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
2068 because of that same extra output line.
2070 * NEWS: Document minor wording changes in diagnostics of
2071 Bison-generated parsers.
2072 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
2073 Remove unused formals. All uses changed.
2074 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
2075 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
2076 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
2077 Rename yyoverflowab to yyexhaustedlab.
2078 When memory exhaustion occurs during syntax-error reporting,
2079 report it separately rather than in a single diagnostic; this
2081 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
2082 (Memory Exhausted): Renamed from Parser Stack Overflow.
2083 Revamp wording slightly to prefer "memory exhaustion".
2084 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
2086 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
2088 Add i18n support to the GLR skeleton. Partially fix the C++
2089 skeleton; a C++ expert needs to finish this. Remove debugging
2090 msgids; there's little point to having them translated, since they
2091 can be understood only by someone who can read the
2092 (English-language) source code.
2094 Generate runtime-po/bison-runtime.pot automatically, so that we
2095 don't have to worry about garbage getting in that file. We'll
2096 make sure after the next official release that old msgids don't
2098 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
2100 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
2102 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
2103 Fix typos in explanations of the runtime file.
2104 * bootstrap: Change gettext keyword from YYI18N to YY_.
2105 Use standard Makefile.in.in in runtime-po, since we'll arrange
2106 for backward-compatible bison-runtime.po files in a different way.
2107 * data/glr.c (YY_): New macro, from yacc.c.
2108 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2109 Translate messages intended for users.
2110 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
2111 the wording in the other skeletons. We don't know that the memory
2113 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
2114 Use same method that yacc.c uses.
2115 Don't translate debugging messages.
2116 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
2117 it doesn't work (yet), and requires C++ expertise to fix.
2118 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
2119 Move defn to a more logical place, to be consistent with other
2121 Don't translate debugging messages.
2122 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
2123 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
2124 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
2125 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
2127 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
2128 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
2130 * tests/glr-regression.at (Badly Collapsed GLR States):
2132 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2133 yylex should return 0 at EOF rather than aborting.
2135 Improve tests for stack overflow in GLR parser.
2136 Problem reported by twlevo@xs4all.nl.
2137 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
2139 (yyStackOverflow): Just longjmp, but with value 2 so that caller
2140 can handle the problem.
2141 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
2142 (yyparse): New local variable yyresult to record the result.
2143 Use result of setjmp to set it, rather than storing itinto
2145 (yyDone): Remove label.
2146 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
2147 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
2148 if YYABORT is used).
2149 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
2150 yyparse status; put status > 1 into diagnostic.
2151 Check that status==2 works.
2152 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
2153 Use exit status 3 for failure to open (which shouldn't happen).
2155 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
2157 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
2158 1 on syntax error; just let yyparse do its thing.
2159 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
2160 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
2161 (Exploding the Stack Size with Alloca):
2162 (Exploding the Stack Size with Malloc):
2163 Expect exit status 2, not 1, since the parser is supposed to blow
2164 its stack. Problem reported by twlevo@xs4all.nl.
2166 * data/glr.c (yyparse): Don't assume that the initial calls
2167 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
2168 Print a stack-overflow message and fail instead.
2169 Initialize the line-number information before creating the stack,
2170 so that the stack-overflow message can report line zero safely.
2172 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
2174 Fix problems reported by twlevo@xs4all.nl.
2175 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
2176 (yyuserMerge): Provide a default case if b4_mergers is empty.
2177 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
2178 * tests/glr-regression.at
2179 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2180 Add casts to pacify C++ compilers.
2181 * tests/glr-regression.at (Improper merging of GLR delayed action
2182 sets): Declare yylex before using it.
2183 * tests/Makefile.am (maintainer-check-g++): Fix a stray
2184 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
2185 test for valgrind; valgrind is independent of g++.
2186 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
2187 for compatibility with POSIX 1003.1-2001 (if running coreutils).
2188 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
2189 Use a destructor, so that we can expand the stack. Change
2190 YYSTYPE to char * so that we can free it. Cast result of malloc.
2192 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2194 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
2195 a valgrind failure. Problem reported by twlevo@xs4all.nl.
2197 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
2199 * PACKAGING: New file, suggested by Bruno Haible and taken from
2200 similar wording in gettext's PACKAGING file.
2201 * NEWS: Mention PACKAGING.
2202 * Makefile.am (EXTRA_DIST): Add PACKAGING.
2204 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
2206 * NEWS: Document recent i18n improvements.
2207 * bootstrap: Get runtime translations into runtime-po.
2208 Create runtime-po files automatically, if possible.
2209 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
2210 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
2211 does not infringe on the user's name space.
2212 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
2213 * doc/bison.texinfo (Internationalization): Revamp the English
2214 and Texinfo syntax a bit, to try to make it clearer.
2215 (Bison Options, Option Cross Key): Mention --print-localedir.
2216 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
2217 YYENABLE_NLS. Quote a bit more.
2218 * runtime-po/.cvsignore: New file.
2219 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
2220 * runtime-po/Rules-quot: Remove; now created by bootstrap.
2221 * runtime-po/quot.sed: Likewise.
2222 * runtime-po/boldquot.sed: Likewise.
2223 * runtime-po/en@quot.header: Likewise.
2224 * runtime-po/en@boldquot.header: Likewise.
2225 * runtime-po/insert-header.sin: Likewise.
2226 * runtime-po/remove-potcdate.sin: Likewise.
2227 * runtime-po/Makevars: Likewise.
2228 * runtime-po/LINGUAS: Likewise.
2229 * runtime-po/de.po: Likewise; we will rely on the translation project
2230 to maintain this, so "bootstrap" should get it.
2231 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
2233 * src/main.c (main): Bind the bison-runtime domain, too.
2235 2005-07-12 Bruno Haible <bruno@clisp.org>
2237 * data/yacc.c: Include <libintl.h> when NLS is enabled.
2238 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
2239 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
2240 * runtime-po: New directory.
2241 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
2242 $(DOMAIN).pot-update rule, so that old messages are never dropped.
2243 * runtime-po/Rules-quot: New file, copied from po/.
2244 * runtime-po/quot.sed: Likewise.
2245 * runtime-po/boldquot.sed: Likewise.
2246 * runtime-po/en@quot.header: Likewise.
2247 * runtime-po/en@boldquot.header: Likewise.
2248 * runtime-po/insert-header.sin: Likewise.
2249 * runtime-po/remove-potcdate.sin: Likewise.
2250 * runtime-po/Makevars: New file.
2251 * runtime-po/POTFILES.in: New file.
2252 * runtime-po/LINGUAS: New file.
2253 * runtime-po/bison-runtime.pot: New file.
2254 * runtime-po/de.po: New file.
2255 * m4/bison.m4: New file.
2256 * Makefile.am (SUBDIRS): Add runtime-po.
2257 (aclocaldir, aclocal_DATA): New variables.
2258 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
2260 * src/getargs.c (usage): Document --print-localedir option.
2261 (PRINT_LOCALEDIR_OPTION): New enum item.
2262 (long_options): Add --print-localedir option.
2263 (getargs): Handle --print-localedir option.
2264 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
2265 (Internationalization): New section.
2267 2005-07-12 Akim Demaille <akim@epita.fr>
2269 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
2270 for consistency with the rest of the code.
2271 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
2274 2005-07-12 Akim Demaille <akim@epita.fr>
2276 * src/parse-gram.y: Use %printer instead of YYPRINT.
2278 2005-07-12 Akim Demaille <akim@epita.fr>
2280 * src/symtab.h, src/symtab.c (symbol_print): New.
2281 * src/symlist.h, src/symlist.c (symbol_list_print): New.
2282 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
2284 2005-07-12 Akim Demaille <akim@epita.fr>
2286 * data/glr.c (b4_syncline): Fix (swap) the definitions of
2287 b4_at_dollar and b4_dollar_dollar.
2289 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
2291 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
2292 and Pennello's paper.
2294 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
2296 * data/yacc.c (yyparse): Undo previous patch. Instead,
2297 set yylsp[0] and yyvsp[0] only if the initial action
2298 sets yylloc and yylval, respectively.
2300 * data/yacc.c (yyparse): In the initial action, set
2301 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
2302 This avoids the use of undefined variables if the initial
2303 action does not set yylloc and/or yylval.
2305 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2307 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
2308 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
2309 Remove from CVS. These files are automatically generated.
2310 * examples/extexi: Clarify that this file is now part of Bison,
2311 not GNU M4, and that it works with any POSIX-compatible Awk.
2312 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
2313 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
2314 so that we also get calc++-parser.yy. Geneate it.
2315 Use $(AWK), not gawk, since any conforming Awk will do.
2316 Put comment before action, since older 'make' can't handle comment
2318 $(BUILT_SOURCES): List all built sources, not just some of them.
2319 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
2320 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
2321 $($(calc_sources_generated)): Remove unnecessary test for existence
2322 of target. (This had a shell syntax error anyway; a stray "x".)
2323 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
2325 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
2327 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
2328 implied by the other modules.
2330 2005-07-06 Akim Demaille <akim@epita.fr>
2332 Bind examples/calc++ to the package.
2333 * examples/calc++/Makefile: Remove, replaced by...

2335 * examples/calc++/test: Remove input.
2336 * examples/calc++/compile: Remove.
2337 * examples/Makefile.am: New.
2338 * configure.ac, Makefile.am: Adjust.
2339 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
2341 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
2343 * data/glr.c (yyFail): Drastically simplify; since the format argument
2344 never had any % directives, we can simply pass it to yyerror.
2345 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
2346 be modified later, as that is the usual style in glr.c.
2347 Problems reported by Paul Hilfinger.
2349 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
2350 and size overflow errors.
2351 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
2352 in case the user prolog sets feature-test macros like _GNU_SOURCE.
2353 (YYSIZEMAX): New macro.
2354 (yystpcpy): New function, taken from yacc.c.
2355 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
2356 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
2357 so that we don't have to maintain their signatures.
2358 (yyFail): Check for buffer overflow, by using vsnprintf rather
2359 than vsprintf. Allocate a bigger buffer if possible.
2360 Report an error if buffer allocation fails.
2361 (yyStackOverflow): New function.
2362 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
2363 the initialization was successful. It might fail if storage was
2365 (yyexpandGLRStack): Add more checks for storage allocation failure.
2366 Use yyStackOverflow to report failures.
2367 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
2368 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
2369 Don't assume stack number fits in int.
2370 (yysplitStack): Check for storage allocation failure.
2371 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
2372 can print diagnostics on storage allocation failure. All callers
2374 (yyresolveValue): Use yybool for boolean.
2375 (yyreportSyntaxError): Check for size-calculation overflow.
2376 This code is taken from yacc.c.
2377 (yyparse): Check for storage allocation errors when allocating
2380 2005-07-05 Akim Demaille <akim@epita.fr>
2382 Extract calc++ from the documentation.
2383 * doc/bison.texinfo (Calc++): Add the extraction marks.
2384 * examples/extexi: New, from the aborted GNU Programming 2E.
2385 Separate the different paragraph of a file with empty lines.
2386 * examples/Makefile: Use it to extract the whole calc++ example.

2413 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2414 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2415 which stems from the 2005-05-27 patch.
2417 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2419 * data/glr.c: Modify treatment of unused parameters to permit use
2420 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2422 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2424 Fix infringement on user name space reported by Janos Zoltan Szabo.

2432 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2434 Fix infringement on user name space reported by Bruno Haible.
2435 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2436 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2437 the user's name space.
2438 (alloca): Include <stdlib.h> to get it, if it's not built in.
2439 (YYMALLOC, YYFREE): Define only if needed.
2440 (malloc, free): Declare, but only if needed, as this infringes on
2441 the user name space.
2443 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2445 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
2446 * lib/bitset.c (bitset_print): Don't assume size_t can be printed

2468 * NEWS: Version 2.0a.
2470 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2471 the previous change.
2473 Various maintainer cleanups.
2474 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2475 conftest*, for benefit of CVS commands run at the same time as
2476 "configure". Add build-aux, since "bootstrap" now creates it and
2478 * Makefile.cfg (move_if_change): Remove.
2479 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2480 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

2488 this is now the recommended name.
2489 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2490 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2491 ylwrap. These files now go into build-aux.
2492 * config/move-if-change: Remove.
2493 * config/prev-version.txt: Bump from 1.75 to 2.0.
2495 * bootstrap: Add stdio-safer, unistd-safer modules.

2499 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2500 * lib/subpipe.c: Include "unistd-safer.h".
2501 (create_subpipe): Make sure all the newly-created
2502 file descriptors are > 2, so that diagnostics don't
2503 get sent down them (which might cause Bison to hang, in theory).
2504 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2505 * src/files.c (xfopen): Use fopen_safer, not fopen.
2507 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2508 yesterday's yacc.c fix.
2510 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

2517 don't set yychar to EMPTY.
2518 (yyoverflowlab): Don't call destructor.
2519 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2520 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2521 since we no longer output the message "discarding lookahead token
2524 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2526 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2527 fix a small glitch in debugging output.
2528 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2529 after YY_SYMBOL_PRINT where needed.
2531 (struct yyGLRState): Add some comments.
2532 (struct yySemanticOption): Add some comments.
2533 (union yyGLRStackItem): Add comment.

2580 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
2582 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
2583 Problem reported by Ralf Menzel.
2585 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2587 * tests/actions.at: Test that stack overflow invokes destructors.
2588 From Marcus Holland-Moritz.
2589 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2591 (yyreturn): to here. That way, destructors are called properly
2592 even if the stack overflows, or the user calls YYACCEPT or
2593 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2594 (yyoverflowlab): Destroy the lookahead.
2596 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2598 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2600 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2602 * NEWS: Bison-generated C parsers no longer quote literal strings
2603 associated with tokens.
2604 * src/output.c (prepare_symbols): Don't escape strings,
2605 since users don't want to see C escapes.
2606 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2608 * tests/input.at (Torturing the Scanner): Likewise.
2609 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2611 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2613 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2614 the data size is known to be too small and we can't increase it.
2615 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2617 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2619 * src/parse-gram.y: Include quotearg.h.
2620 (string_as_id): Quote $1 before using it as a key, since the
2621 lexer no longer quotes it for us.
2622 (string_content): Don't strip quotes, since lexer no longer
2624 * src/scan-gram.l: Include quotearg.h.
2626 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2627 a key, since the rest of the lexer doesn't quote it.
2628 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2629 * tests/regression.at (Token definitions): Check for backslashes
2632 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2633 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2634 (yyparse): Revamp code to generate long syntax error message, to
2635 make it easier to translate, and to avoid problems with arithmetic
2636 overflow. Change "virtual memory" to "memory" in diagnostic, since
2637 we don't know whether the memory is virtual.
2639 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2641 * NEWS: Bison-generated C parsers now use the _ macro to
2643 * data/yacc.c (_) [!defined _]: New macro.
2644 All English strings wrapped inside this macro.
2645 * doc/bison.texinfo (Bison Parser): Document _.
2646 * po/POTFILES.in: Include src/parse-gram.c, since it now
2647 includes translateable strings that parse-gram.y doesn't.
2649 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2651 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2652 reverting the 2004-10-11 change to this function.
2653 (symbol_check_alias_consistency): Don't call symbol_type_set
2654 if the type name is already correct.
2655 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2657 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2659 * tests/regression.at (Token definitions): Don't use a token named
2660 c, as that generates a "#define c ..." that runs afoul of buggy
2661 stdlib.h that uses the identifier c as a member of struct
2662 drand48_data. Problem reported by Horst Wente.
2664 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2666 * bootstrap: Change translation URL from
2667 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2668 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2669 redirection glitches. Problem reported by twlevo@xs4all.nl.
2671 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2673 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2674 after operands; POSIX says this isn't portable for the c99 command.
2676 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2678 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2679 immediately if a data overrun has occurred; this may help us track
2680 down what may be a spurious failure on MacOS.
2682 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2684 Respond to problems reported by twlevo@xs4all.nl.
2686 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
2688 * src/vcg.h: Comment fix.
2689 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2690 (G_CMAX): Change to -1 instead of INT_MAX.
2692 * data/yacc.c (yyparse): Omit spaces before #line.
2694 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2696 * src/tables.c (state_number_to_vector_number): Put it inside an
2697 "#if 0", since it's not currently used. Problem reported by
2700 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2702 * src/output.c (escaped_output): Renamed from
2703 escaped_file_name_output, since we now use it for symbol tags as
2704 well. All uses changed.
2705 (symbol_destructors_output, symbol_printers_output):
2706 Escape symbol tags too.
2707 Problem reported by Matyas Forstner in
2708 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2710 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2712 * src/output.c (user_actions_output, token_definitions_output,
2713 symbol_destructors_output, symbol_printers_output): Likewise.
2714 * src/reader.c (prologue_augment): Likewise.
2715 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2717 * src/vcg.c (output_edge): Don't quote linestyle arg.
2718 Problem reported by twlevo@xs4all.nl.
2720 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2722 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2723 example, reported by Derek M Jones. Also, make the example even
2724 more outrageous, to better illustrate how bad the problem is.
2726 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2728 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2729 putsym. Typo reported by Sebastian Piping.
2731 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2733 * doc/bison.texinfo (Language and Grammar): some -> same
2734 (Epilogue): int he -> in the
2735 Typos reported by Sebastian Piping via Justin Pence.
2737 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2739 * tests/glr-regression.at (Improper handling of embedded actions
2740 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2741 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2742 with dollar signs in test names.
2743 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2744 for a similar reason.
2746 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2748 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2749 wants to redefine G_VIEW.
2751 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
2753 * src/vcg.c (get_view_str): Remove case for normal_view.
2754 Problem reported by twlevo@xs4all.nl.
2756 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>

2759 Problem reported by twlevo@xs4all.nl.
2761 * doc/bison.texinfo: Change @dircategory from "GNU programming
2762 tools" to "Software development". Requested by Richard Stallman
2765 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
2767 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
2768 Problem reported by twlevo@xs4all.nl.
2770 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2772 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2773 keyword; it's not needed with modern compilers, and it doesn't
2774 affect correctness with older compilers. Suggested by
2777 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2779 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2780 gcc -Wswitch-default.
2781 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2782 * data/yacc.c (yyparse): Likewise.
2784 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2786 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2787 already. Let config.h define any nonstandard values.
2789 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2791 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2792 for the benefit of slower hosts. Problem reported by
2795 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2797 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2798 being defined and not used.
2799 * data/lalr1.cc (yyparse): Likewise.
2800 Use "if (false)" rather than "if (0)".
2802 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2804 * TODO: Mention that we should allow NUL bytes in tokens.
2806 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>

2813 * src/getargs.c (version): Happy new year; update overall
2814 program copyright date from 2004 to 2005.
2816 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2817 Problem reported by Hans Aberg.
2818 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2819 (Output file names.): Add a test for the case when standard output
2822 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2824 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2825 to fix an oversight in the Bison 2.0 manual.
2827 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2829 * NEWS: Version 2.0. Reformat the existing news items since
2830 1.875, so that related items are grouped together.
2831 * configure.ac (AC_INIT): Bump version to 2.0.
2832 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2834 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2835 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2836 otherwise, we're not testing alloca. Unfortunately there's no
2837 simple way to consult HAVE_ALLOCA here.
2839 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2842 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2843 hand. This avoids a warning about comparing int to size_t when
2844 GCC warnings are enabled.
2846 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2848 * NEWS: Bison-generated parsers no longer default to using the
2849 alloca function (when available) to extend the parser stack, due
2850 to widespread problems in unchecked stack-overflow detection.
2851 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2852 responsibility to set it to a positive value. This lets the user
2853 specify a value that is not a preprocessor constant.
2854 * data/yacc.c (YYMAXDEPTH): Likewise.
2855 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2856 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2857 to be a compile-time constant. However, explain the constraints on it.
2858 Also, explain the constraints on YYINITDEPTH.
2859 (Table of Symbols): Explain that alloca is no longer the default.
2860 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2863 * doc/bison.texinfo (Location Default Action): Mention that n must
2864 be zero when k is zero. Suggested by Frank Heckenbach.
2866 2004-12-22 Akim Demaille <akim@epita.fr>
2868 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
2869 (parser::state_type, parser::semantic_type, parser::location_type):
2870 Private, not public.
2871 (parser::parse): Return ints, not bool.
2872 Returning a bool introduces a problem: 0 corresponds to false, and
2873 it seems weird to return false on success. Returning true changes
2874 the conventions for yyparse.
2875 Alternatively we could return void and send an exception.
2876 There is no clear consensus (yet?).
2877 (state_stack, semantic_stack, location_stack): Rename as...
2878 (state_stack_type, semantic_stack_type, location_stack_type): these.
2879 Private, not public.

2881 * tests/testsuite.at, tests/Makefile.am: Adjust.
2883 2004-12-21 Akim Demaille <akim@epita.fr>
2885 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
2887 2004-12-21 Akim Demaille <akim@epita.fr>
2889 Don't impose std::string for filenames.
2891 * data/lalr1.cc (b4_filename_type): New.
2892 (position::filename): Use it.
2893 (parser.hh): Move the inclusion of stack.hh and location.hh below
2894 the user code, so that needed headers for the filename type can be
2896 Forward declare them before the user code.
2897 * tests/Makefile.am (check-local, installcheck-local): Pass
2898 TESTSUITEFLAGS to the TESTSUITE.
2900 2004-12-20 Akim Demaille <akim@epita.fr>
2902 Use more STL like names: my_class instead of MyClass.
2904 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
2905 (SemanticStack, SemanticType, StateStack, StateType)
2906 (TokenNumberType, Stack, Slice, Traits, Parser::location)
2907 (Parser::value): Rename as...
2908 (location_stack, location_type, rhs_number_type, semantic_stack)
2909 (semantic_type, state_stack, state_type, token_number_type, stack)
2910 (slice, traits, parser::yylloc, parser::yylval): these.
2912 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
2914 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
2916 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
2917 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
2919 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
2921 Remove uses of 'short int' and 'unsigned short int'. This raises
2922 some arbitrary limits. It uses more memory but nowadays that's
2923 not much of an issue.
2925 This change does not affect the generated parsers; that's a different
2926 task, as some users will want to conserve memory there.
2928 Ideally we should use size_t to represent all object counts, and
2929 something like ptrdiff_t to represent signed differences of object
2930 counts; but that will require more code-cleanup than I have the
2931 time to do right now.
2933 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
2934 Use size_t, not int or short int, to count objects.
2935 * src/closure.c (nritemset, closure): Likewise.

2947 errs, reductions): Likewise.

2950 * src/tables.c (vector_number, tally, action_number,

2952 * src/output.c (muscle_insert_short_int_table): Remove.
2954 2004-12-17 Akim Demaille <akim@epita.fr>
2956 * data/lalr1.cc: Extensive Doxygenation.
2957 (error_): Rename as...
2958 (error): this, since it is visible to the user.
2960 (Parser::message): Now an automatic variable from...
2961 (Parser::yyreport_syntax_error_): here.
2962 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
2964 * tests/input.at: Escape $.
2966 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
2968 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
2969 Parenthesize rhs to avoid obscure problems with mistakes like
2970 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
2971 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2972 b4_rhs_location): Likewise.
2973 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2974 b4_rhs_location): Likewise.
2976 2004-12-16 Akim Demaille <akim@epita.fr>
2978 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
2979 yacc.c: be sure to stay within yycheck_.
2980 * tests/actions.at: Re-enable C++ tests.
2982 2004-12-16 Akim Demaille <akim@epita.fr>
2984 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
2987 2004-12-16 Akim Demaille <akim@epita.fr>
2989 Use #define to handle the %name-prefix.
2991 * data/glr.c, data/yacc.c: Comment changes.
2992 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
2993 so that one can refer to yylex in the parser file, and have it
2994 renamed, as is the case with other skeletons.
2996 2004-12-16 Akim Demaille <akim@epita.fr>
2998 Move lalr1.cc internals into yy*.

3018 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
3020 Fix some problems reported by twlevo at xs4all.
3021 * src/symtab.c (symbol_new): Report an error if the input grammar
3022 contains too many symbols. This is better than calling abort() later.
3023 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
3024 (struct node, struct graph):
3025 Rename member expand to stretch. All uses changed.
3026 (struct graph): Remove member layoutalgorithm. All uses removed.

3032 2004-12-15 Akim Demaille <akim@epita.fr>
3034 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
3035 Add more Doxygen comments.
3036 (symprint_, stack_print_, reduce_print_, destruct_, pop)
3037 (report_syntax_error_, translate_): Rename as...
3038 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
3039 (yypop_, yyreport_syntax_error_, yytranslate_): this.
3041 2004-12-15 Akim Demaille <akim@epita.fr>
3043 * data/lalr1.cc (lex_): Rename as...
3045 Move the trace here.
3046 Take the %name-prefix into account.
3047 Reported by Alexandre Duret-Lutz.
3049 2004-12-15 Akim Demaille <akim@epita.fr>
3051 Simplify the C++ parser constructor.
3053 * data/lalr1.cc (debug_): Rename as...
3054 (yydebug_): so that the parser's internals are always in the yy*
3057 (b4_parse_param_decl): Remove the leading comma as it is now only
3058 called as unique argument list.
3059 (Parser::Parser): Remove the constructor accepting a location and
3060 an initial debugging level.
3061 Remove from the other ctor the argument for the debugging level.
3062 (debug_level_type, debug_level, set_debug_level): New.
3064 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
3067 2004-12-15 Akim Demaille <akim@epita.fr>
3069 Remove b4_root related material: failure experiment
3070 (which goal was to allow to derive from a class).
3072 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
3073 definitions and uses.
3075 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
3077 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
3078 not 2, since it's not portable to subtract 1 from the start of an
3079 array. The new item 0 is never set or used. All uses changed.
3081 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
3082 the default definition of YYLLOC_DEFAULT. Problem reported
3083 by Frank Heckenbach.
3085 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
3087 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
3088 the normal case and one for the error case. Just use the
3089 first one uniformly. Problem reported by Frank Heckenbach.
3090 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
3091 use exactly the same macro in both places.
3092 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
3093 so that the normal-case YYRHSLOC works for the error case too.
3095 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
3096 (YYLLOC_DEFAULT): Use the same macro as glr.c.
3097 * doc/bison.texinfo (Location Default Action): Don't claim that
3098 we have an array of locations. Use the same macro for both glr
3099 and lalr parsers. Mention YYRHSLOC. Mention what happens when
3102 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
3104 * HACKING: Update email addresses to send announcements to.

3111 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
3113 * src/scan-skel.l: Include "complain.h", for "fatal".
3115 * src/relation.h (relation_print, relation_digraph):
3116 Relation sizes are of type relation_node, not size_t (this is
3117 merely a doc fix, since the two types are equivalent).
3118 (relation_transpose): Relation sizes are of type relation_node,
3120 * src/relation.c: Likewise.
3121 (top, infinity): Now of type relation_node, not int.
3122 (traverse, relation_transpose): Use relation_node, not int.
3124 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
3125 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
3126 (yyparse): Remove unused local introduced in 2004-10-25 patch.
3128 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
3129 specifying whether the test should be skipped. Use it tp
3130 specify that the [%defines %skeleton "lalr1.cc"] tests currently
3131 fail on some hosts, and should be skipped.
3133 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3135 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
3136 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
3137 unless otherwise specified below.
3139 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
3140 to allocate kernel_base, kernel_items, kernel_size, since
3141 they needn't be initialized to 0.
3142 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
3143 * src/closure.c (new_closure): Likewise, for itemset.

3159 (goto_actions): Likewise for state_count.
3160 (pack_table): Likewise for base, pos, check.
3161 (tables_generate): Likewise for width.
3163 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
3164 for initial core. Just have a separate core, so we needn't worry
3165 about whether kernel_size and kernel_base are initialized.
3167 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
3168 kernel_size, kernel_items): Remove unnecessary initialization.

3173 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
3174 conflrow, conflict_table, conflict_list, table, check):
3177 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
3178 This is because all callers pass unsigned int.
3179 * src/closure.h (new_closure): Likewise.
3181 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
3182 (build_relations): Initialize includes[i] in all cases.
3183 * src/reader.c (packgram): Always initialize rules[ruleno].prec
3184 and rules[ruleno].precsym. Initialize members in order.

3187 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
3189 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
3190 conflict_list[0] was always 0, but now it isn't initialized.
3192 * src/table.c (table_grow): When conflict_table grew, the grown
3193 area wasn't cleared. Fix this.
3195 * lib/.cvsignore: Add strdup.c, strdup.h.
3196 * m4/.cvsignore: Add strdup.m4.
3198 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
3200 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
3201 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
3202 GOTO_NUMBER_MAXIMUM, since we occasionally compute
3203 ngotos + 1 without checking for overflow.
3204 (build_relations): Use END_NODE, not -1, to denote end of edges.
3205 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
3206 build_relations): Use goto_number, not int, for goto numbers.

3211 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
3212 of #defining from yystype.
3213 Don't typedef yystype, C++ does not need it.
3214 This lets it possible to forward declare it as union.
3216 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
3218 * bootstrap (gnulib_modules): Add extensions.
3219 Problem reported by Jim Meyering.

3226 recent change to gnulib xalloc.h.
3227 Problem reported by Jim Meyering.
3229 2004-11-17 Akim Demaille <akim@epita.fr>

3236 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
3239 Use it instead of cdebug_.
3240 (Parser::debug_stream, Parser::set_debug_stream): New.
3241 (Parser::symprint_): Define cdebug_ for temporary backward
3243 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
3246 2004-11-17 Akim Demaille <akim@epita.fr>

3256 Problem reported by Frank Heckenbach.
3258 2004-10-25 Akim Demaille <akim@epita.fr>
3260 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
3261 Introduce another definition to address simple location arrays.
3262 (yyGLRStack): New member: yyerror_range.
3263 (yyrecoverSyntaxError, yyparse): Update it.
3264 (yyrecoverSyntaxError): Use it when shifting the error token to
3265 have an accurate range, equivalent to the one computed by both
3266 yacc.c and lalr1.cc.
3267 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
3268 that column numbers start at column 0, as per GNU Coding
3269 Standards, the others tests, and the doc.
3270 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
3271 Adjust to the above change (first column is 0).
3272 And adjust the location of the "<error>", now covering the whole
3275 2004-10-22 Akim Demaille <akim@epita.fr>
3276 and Paul Eggert <eggert@cs.ucla.edu>
3278 Remove some arbitrary limits on goto numbers and relations.
3279 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
3280 initial values, since they're never used.
3281 (set_goto_map): ngotos is now unsigned, so test for overflow
3282 by seeing whether it wraps around to zero.
3283 * src/lalr.h (goto_number): Now size_t, not short int.
3284 (GOTO_NUMBER_MAXIMUM): Remove.
3285 * src/relation.c (relation_print, traverse, relation_transpose):
3286 Check for END_NODE rather than looking at sign.
3287 * src/relation.h (END_NODE): New macro.
3288 (relation_node): Now size_t, not short int.
3290 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
3292 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
3293 keyword, not an identifier. Problem reported by Baron Schwartz in
3294 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
3296 2004-10-11 Akim Demaille <akim@epita.fr>
3298 * src/symtab.c (symbol_check_alias_consistency): Also check
3299 type names, destructors, and printers.
3300 Reported by Alexandre Duret-Lutz.
3301 Recode the handling of associativity and precedence in terms
3302 of symbol_precedence_set.
3303 Accept no redeclaration at all, not even equal to the previous
3305 (redeclaration): New.
3306 Use it to factor redeclaration complaints.
3307 (symbol_make_alias): Don't set the type of the alias, let
3308 symbol_check_alias_consistency do it as for other features.
3309 * src/symtab.h (symbol): Add new member prec_location, and
3311 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
3312 * tests/input.at (Incompatible Aliases): New.
3314 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
3316 .cvsignore fixes to accommodate gnulib changes,
3317 and the practice of naming build directories "_build".

3319 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
3320 * m4/.cvsignore: Add "*_gl.m4".
3322 2004-10-06 Akim Demaille <akim@epita.fr>
3324 * src/parse-gram.y (add_param): Fix the truncation of trailing
3327 2004-10-05 Akim Demaille <akim@epita.fr>
3329 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3330 whether the reducion was empty or not. This leaves room to
3331 improve the use of YYLLOC_DEFAULT in such a case.
3332 lalr1.cc is still experimental, so changing this is acceptable.
3333 And finally, there are probably not many users who changed the
3334 handling of locations in GLR, so changing is admissible too.
3336 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3337 empty reduction, set @$ to an empty location ending the previously
3339 Adjust uses to make sure the code is triggered on empty
3341 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
3342 expected output: empty reductions have empty locations.
3344 2004-09-29 Akim Demaille <akim@epita.fr>
3346 * data/lalr1.cc: Move towards a more standard C++ coding style
3347 for templates: Class < T > -> Class<T>.
3349 2004-09-29 Akim Demaille <akim@epita.fr>
3351 * data/lalr1.cc: Reinstall the former ctor, for sake of
3352 compatibility, but warn it will be removed.
3353 Move towards a more standard C++ coding style (i.e., type *var ->
3356 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
3358 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
3359 since it's less likely to work if NULs are involved in the future.
3361 2004-09-27 Akim Demaille <akim@epita.fr>
3363 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
3365 2004-09-27 Akim Demaille <akim@epita.fr>
3367 * data/lalr1.cc (b4_parse_param_decl_1): New.
3368 (b4_parse_param_decl): Use it to have different names between attribute
3370 (b4_cc_constructor_call): Likewise.
3372 2004-09-24 Akim Demaille <akim@epita.fr>
3374 * src/parse-gram.y (add_param): Strip the leading and trailing
3375 blanks from a formal argument declaration.
3376 (YY_LOCATION_PRINT): New.
3378 2004-09-24 Akim Demaille <akim@epita.fr>
3380 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
3383 2004-09-24 Akim Demaille <akim@epita.fr>
3385 * doc/bison.texinfo (Table of Symbols): Sort.
3387 2004-09-21 Akim Demaille <akim@epita.fr>
3389 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
3390 the useless parentheses.
3391 Suggested by Paul Eggert.
3393 2004-09-20 Akim Demaille <akim@epita.fr>
3395 Let the initial-action act on the look-ahead, and use it for the
3396 "initial push" (corresponding to an hypothetical beginning-of-file).
3397 And let lalr1.cc honor %initial-action.
3399 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
3401 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3402 (Parser::Parser): Remove the ctor that used to initialize it.
3403 (Parser::parse): Like in the other skeletons, issue the "starting
3404 parse" message before any action.
3405 Honor %initial-action.
3406 Initialize the stacks with the lookahead.
3407 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3409 Push them in the stacks.
3410 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3412 2004-09-20 Akim Demaille <akim@epita.fr>
3414 * doc/bison.texinfo (Initial Action Decl): New.
3416 2004-09-20 Akim Demaille <akim@epita.fr>
3418 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3419 clearer criterion to define it.
3420 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3421 When reducing on an empty RHS, use the latest stacked location as
3423 yylloc is not always available.
3424 * data/glr.c: Likewise.
3425 Also, honor initial-actions.
3427 2004-09-20 Akim Demaille <akim@epita.fr>
3429 * data/yacc.c (YY_LOCATION_PRINT): New.
3430 Define when we know YYLTYPE's structure, i.e., when the default
3431 YYLLOC_DEFAULT is used.
3432 * data/c.m4 (b4_yysymprint_generate): Use it.
3433 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3434 value of the result.
3435 (error_start_): Replace with...
3436 (error_range_): this location array.
3437 This allows to replace code relying on the implementation of
3438 locations by portable code.
3439 * data/yacc.c (yylerrsp): Replace with...
3440 (yyerror_range): this.
3441 Every time a token is popped, update yyerror_range[0], to have an
3442 accurate location for the error token.
3443 * data/glr.c (YY_LOCATION_PRINT): New.
3444 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3445 deference a pointer.
3446 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3447 report the location in %printers.
3449 * src/scan-skel.l: Instead of abort, report error messages to ease
3450 understanding skeleton scanning failures.
3452 2004-09-16 Akim Demaille <akim@epita.fr>
3454 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3455 (iterator, const_iterator): these, to be more in the C++ spirit.
3456 Also, return reverse iterators so that when displaying the stack
3457 we display its bottom first.
3458 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3460 We should probably use vector here though.
3462 2004-09-16 Akim Demaille <akim@epita.fr>
3464 Have more complete shift traces.
3466 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3467 to report Shifts instead of ad hoc YYDPRINTF invocations,
3468 including for the error token.
3469 * data/lalr1.cc (symprint_): Output the location.
3470 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3471 output the location within the %printer.
3472 Activate GLR tests, at least to make sure they compile properly.
3473 They still don't pass though.
3474 * tests/calc.at: Adjust expect verbose output, since now "Entering
3475 state..." is on a different line than the "Shifting" message.
3477 2004-09-08 Akim Demaille <akim@epita.fr>
3479 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3480 Bison directive from the Bison file to the invocation of this
3481 macro, so that these directives are passed to
3482 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3483 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3484 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3485 the extra Bison directives instead of the whole series.
3486 Change the grammar so that there are recoverable errors, and
3487 unrecoverable errors. Now we can have the parser give up before
3488 consuming the whole input. As a result we now can observe that
3489 the lookahead is freed when needed.
3490 Change the parser source to parse argv[1] instead of a hard coded
3492 Simplify yylex, and give a value and location to EOF.
3493 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3494 passed directives already coded in the file.
3495 Add some tests to check the location of "error".
3496 For some tests, the C++ parser is correct, and not yacc.c.
3497 For other tests, they provide different, but unsatisfying, values,
3498 so keep the C++ value so that at least one parser is "correct"
3499 according to the test suite.
3500 (Actions after errors): Remove, this is subsumed by the
3501 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3503 2004-09-06 Akim Demaille <akim@epita.fr>
3505 * data/lalr1.cc: Adjust the indentation of the labels.
3509 2004-09-06 Akim Demaille <akim@epita.fr>
3511 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3512 argument, an informative message.
3513 Call YY_SYMBOL_PRINT.
3514 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3515 * data/lalr1.cc (destruct_): Likewise.
3516 In addition, no longer depend on b4_yysymprint_generate and
3517 b4_yydestruct_generate to generate these functions, do it "by
3520 2004-09-03 Akim Demaille <akim@epita.fr>
3522 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3523 invoked, yydestruct the lookahead.
3524 * tests/calc.at (Calculator $1): Update the expected lengths of
3525 traces: there is an added line for the discarded lookahead.
3526 * doc/bison.texinfo (Destructor Decl): Some rewording.
3527 Define "discarded" symbols.
3529 2004-09-02 Akim Demaille <akim@epita.fr>
3531 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3533 2004-09-02 Akim Demaille <akim@epita.fr>
3535 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3536 (YYDSYMPRINTF): Rename as...
3537 (YY_SYMBOL_PRINT): this.
3538 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3540 Use it instead of direct symprint_ calls.
3541 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3544 2004-09-02 Akim Demaille <akim@epita.fr>
3546 * data/lalr1.cc (b4_yysymprint_generate): New.
3547 (symprint_): New member function, defined when YYDEBUG.
3548 Use it consistently instead of token/nterm debugging output by
3550 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
3551 %printer calls to use cdebug_ when using lalr1.cc.
3553 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
3555 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
3556 with #ifdef YYDEBUG.
3558 2004-08-26 Akim Demaille <akim@epita.fr>
3560 * doc/bison.texinfo (Implementing Loops): Rename as...
3561 (Implementing Gotos/Loops): this.
3563 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
3565 Adjust to latest gnulib.
3566 * bootstrap (gnulib_modules): Add xalloc-die.
3567 Set LC_ALL=C so that file names sort consistently.
3568 Prefer the gnulib copies of gettext.m4, glibc21.m4,
3569 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
3570 uintmax_t.m4, ulonglong.m4.
3571 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
3572 po.m4 since we are now using _gl.m4 instead.
3574 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
3576 * src/scan-action.l: Remove. Scanning of semantic actions is
3577 handled in scan-gram.l.
3579 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
3581 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
3583 * src/location.h (struct): The file member is a uniqstr.
3584 (equal_boundaries): Use UNIQSTR_EQ for comparison.
3586 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
3588 Fix bug with non-%union parsers that have printers or destructors,
3589 which led to a Bison core dump. Reported by Peter Fales in
3590 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
3592 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
3593 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
3594 not to our own type.
3595 * src/output.c (symbol_destructors_output, symbol_printers_output):
3596 Don't assume %union.
3597 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
3598 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
3599 UNION-FLAG. All callers changed.
3600 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3601 Use type char, not unsigned int, when declaring an array of char;
3602 this lets us remove a cast.
3603 (Printers and Destructors): Add non-%union test cases.
3605 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3607 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3608 GLR writeups. E.g., avoid frenchspacing and the future tense,
3609 change "lookahead" to "look-ahead", and change "wrt" to "with
3612 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3614 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
3615 New sections, split off from the GLR Parsers section. Put the new
3616 Simple GLR Parser near the start of the GLR section, for clarity.
3617 Rewrite connective text.
3619 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

3675 C++ compiler. (trivial change)
3677 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
3679 Spent a few hours checking out which prerequisite versions the
3680 current sources actually require. I went all the way back to
3681 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3682 a seemingly endless set of combinations of versions more recent
3683 than that. The bottom line is that the current sources require
3684 fairly recent versions of the build tools, and it'll be some work
3686 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3687 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3688 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3689 Add comments explaining why those particular versions are
3692 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
3693 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3694 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3696 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
3697 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
3699 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3701 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
3702 0.11.5. Suggested by Bruno Haible.
3703 * bootstrap: Remove gettext version checking.
3705 * doc/bison.texinfo (Decl Summary): Also mention that %union
3706 can depend on prerequisite types. Problem reported by Tim
3709 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3711 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3712 * README-alpha: Don't tell people not to package this.
3714 * bootstrap: Don't assume $(...) works; use `...` instead.
3715 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3718 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3719 put into the -d output file, and mention what to do if YYSTYPE is
3722 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3724 Undo change made earlier today: it caused autopoint to not bring
3725 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3728 * bootstrap: Check that gettext version matches what's in
3729 configure.ac. Warn users to ignore robots.txt ERROR 404.
3730 * bootstrap: Undo today's earlier change (logged below).
3731 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3733 The gettext version checking is causing more trouble than it's
3734 curing; remove it. Problem reported by Paul Hilfinger.
3736 * bootstrap: Issue a warning that one can expect a message
3737 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3738 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3740 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3742 Ensure that the C++ compiler used for testing actually works on a
3743 simple test program; if not, skip the C++-related tests. Problem
3744 reported by Vin Shelton in:
3745 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
3747 * m4/cxx.m4: New file.

3754 * data/glr.c (yylloc): Output this macro even if locations are not
3755 being generated, as the GLR parser needs it even in that case.
3756 Problem reported by Troy A. Johnson
3757 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
3759 * configure.ac (AC_INIT): Update to 1.875e.

3765 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
3767 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
3768 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3769 lalr1.cc runs afoul of the first, and the last two are no longer
3770 supported by GCC 3.4.0.
3771 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3772 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
3774 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

3810 * src/.cvsignore: Add *.output.
3812 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3813 gets copied to the output file.
3815 2004-04-28 Paul Eggert <eggert@twinsun.com>
3817 Get files from the gnulib and po repositories, instead of relying
3818 on them being in our CVS. Upgrade to latest versions of gnulib
3821 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3822 * bootstrap: Bootstrap from gnulib and po repositories.
3823 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3824 * README-cvs: Document these changes. Remove version numbers from
3825 mentions of build tools, since they change so often. Mention Flex.
3827 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.

3829 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
3830 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3832 (AC_ISC_POSIX): Remove; we no longer support this
3833 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3834 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3835 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3836 Do not check for C89 headers, except for locale.h which is used
3837 by the Yacc library and must port to K&R hosts.
3838 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
3839 Do not check for C89 functions, except for setlocale which is
3840 used by the Yacc library.
3841 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
3842 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

3851 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3852 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
3853 Define to empty, as gnulib.mk will do the rest for us.
3854 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
3856 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
3857 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
3859 * src/files.c: Include gnulib's xstrndup.h.
3861 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
3862 (REALLOC): Use xnrealloc, for likewise.
3863 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
3864 (strnlen, memrchr): Remove decls; functions no longer used.

3887 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
3888 Remove, as these files are now generated automatically
3889 by bootstrap or automake.

3915 support it. (The latest stable gzip doesn't.)
3917 2004-04-27 Paul Eggert <eggert@twinsun.com>
3919 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
3920 case, as stos_ is now used by destructors due to the 2004-02-09
3923 Remove more K&R C support.

3945 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
3947 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
3948 so that this include file can stand alone.
3949 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
3950 does this now. Include subpipe.h first after config.h, to
3951 test whether it can stand alone.
3953 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
3954 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
3957 * tests/synclines.at (%union synch line): Put a dummy member in
3958 the union, because empty unions aren't allowed in C. Caught
3961 2004-04-13 Jim Meyering <jim@meyering.net>
3963 * src/conflicts.c (conflicts_print): Correct format string typo:

4010 (declaration): Replace expected_conflicts with expected_sr_conflicts.
4011 Add %expect-rr rule.
4013 * src/scan-gram.l: Recognize %expect-rr.
4015 * src/conflicts.h (expected_sr_conflicts): Rename from
4017 (expected_rr_conflicts): Declare.
4019 * src/conflicts.c (expected_sr_conflicts): Rename from
4021 (expected_rr_conflicts): Define.
4022 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
4024 Use expected_sr_conflicts in place of expected_conflicts.
4025 Warn if expected_rr_conflicts used in non-GLR parser.
4027 * doc/bison.texinfo: Add documentation for %expect-rr.
4029 2004-03-08 Paul Eggert <eggert@gnu.org>
4031 Add support for hex token numbers. Suggested by Odd Arild Olsen in
4032 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
4034 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
4036 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
4037 * src/scan-gram.l (scan_integer): New function.
4039 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
4040 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
4041 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
4042 Say "long int", not "long", for uniformity with GNU style.
4044 2004-02-25 Paul Eggert <eggert@twinsun.com>
4046 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
4047 compilers. This fixes a problem with Intel's C++ compiler being
4048 chatty, reported by Guido Trentalancia in
4049 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.

4063 error_start_ when erroneous token are discarded.
4064 (Parser::parse) <yyerrlab1>: Compute the location of the error
4065 token so that it covers all the discarded tokens.
4066 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
4067 it can be called with `%skeleton "lalr1.cc"', and do that.
4069 2004-02-02 Paul Eggert <eggert@twinsun.com>
4071 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
4072 $(top_srcdir)/lib and ../lib. This fixes a bug reported
4073 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
4074 There's no need to mention top_builddir since Automake does that
4076 (INCLUDES): Remove, as Automake says it's obsolescent.
4077 Contents migrated into AM_CPPFLAGS as described above.
4078 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
4080 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
4082 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.

4089 resulting parsers are compilable with C++.
4091 2003-12-23 Paul Eggert <eggert@twinsun.com>
4093 * config/depcomp, config/install-sh: Sync with Automake 1.8.
4094 * src/output.c (output_skeleton): Rename local var.
4095 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
4096 Bison tokens, as this runs afoul of the 2003-10-07 change that
4097 disallowed NUL bytes in character constants or string literals.
4099 * tests/local.at: Require Autoconf 2.59's Autotest.
4100 * tests/testsuite.at: Don't include local.at, since we now assume
4101 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
4103 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
4104 multiple inclusion warnings.
4106 2003-12-02 Akim Demaille <akim@epita.fr>

4122 literals, unfortunately.
4123 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
4124 Complain about NUL bytes in character constants or string literals.
4126 2003-10-05 Paul Eggert <eggert@twinsun.com>
4128 * NEWS: Don't document %no-default-prec, as it's still
4130 * doc/bison.texinfo: Document %no-default-prec only if
4131 the defaultprec flag is set. Normally it's not.
4133 2003-10-04 Paul Eggert <eggert@twinsun.com>
4135 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
4136 non-modifiable lvalue, instead of a modifiable one.
4137 * doc/bison.texinfo (Actions): Document that $$ can
4138 be assigned to. Do not claim that $$ and $N are
4139 array element references: user code should not rely on this.
4141 2003-10-01 Paul Eggert <eggert@twinsun.com>
4143 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

4154 * src/print_graph.c (print_graph): Adjust.
4156 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
4157 and Paul Eggert <eggert@twinsun.com>
4159 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
4160 Table of Symbols): Document %default-prec.
4161 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
4162 (grammar_declaration): Set default_prec on %default-prec.

4177 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
4180 2003-08-26 Akim Demaille <akim@epita.fr>
4182 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
4183 "<\#" to avoid magic from Gnus when posting parts of this script.

4192 2003-08-25 Akim Demaille <akim@epita.fr>
4194 * config/announce-gen, Makefile.cfg: New.
4195 * Makefile.am: Adjust.
4196 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
4197 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
4199 2003-08-25 Akim Demaille <akim@epita.fr>
4201 When reducing initial empty rules, Bison parser read an initial
4202 location that is not defined. This results in garbage, and that
4203 affects Bison's own parser. Therefore we need (i) to extend Bison
4204 to support a means to initialize this location, and (ii) to use
4205 this CVS Bison to fix CVS Bison's parser.
4207 * src/reader.h, reader.c (epilogue_augment): Remove, replace
4209 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
4210 * src/parse-gram.y: Adjust.
4211 (%initial-action): New.
4212 (%error-verbose): Since we require CVS Bison, there is no reason
4214 * src/scan-gram.l: Adjust.
4215 * src/Makefile.am (YACC): New, to make sure we use our own parser.
4216 * data/yacc.c (yyparse): Use b4_initial_action.
4218 2003-08-25 Akim Demaille <akim@epita.fr>
4220 * doc/bison.texinfo: Don't promote stdout for error messages.
4222 2003-08-25 Akim Demaille <akim@epita.fr>
4224 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
4225 From Alexandre Duret-Lutz.
4227 2003-08-25 Akim Demaille <akim@epita.fr>
4231 2003-08-25 Akim Demaille <akim@epita.fr>

4243 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
4244 error recovery loops. This patch is based on
4245 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
4246 Also, augment the similarity between lalr1.cc and yacc.c.
4247 Note: the locations of error recovery rules are not correct yet.
4249 * data/lalr1.cc: Comment changes to augment the similarity between
4250 lalr1.cc and yacc.c.
4251 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
4252 (yyerrlab1): Remove, but where it used to be (now the bottom part of
4253 yyerrlab), when hitting EOF, pop the whole stack here instead of
4254 merely falling thru the default error handling mechanism.
4255 (yyerrorlab): New label, with the old contents of YYERROR,
4256 plus the following change: pop the stack of rhs corresponding
4257 to the production that invoked YYERROR. That is how Yacc
4258 behaves (required by POSIX).
4259 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
4262 2003-08-25 Akim Demaille <akim@epita.fr>
4264 Tune local.at so that people can "autom4te -l autotest calc.at -o
4265 calc" for instance, to extract a sub test suite.
4267 * tests/testsuite.at: Move the initialization, Autotest version
4268 requirement, and AT_TESTED invocation into...
4269 * tests/local.at: here.
4270 * tests/testsuite.at: Include it for compatibility with Autoconf
4272 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
4275 2003-08-04 Paul Eggert <eggert@twinsun.com>
4277 Rework code slightly to avoid gcc -Wtraditional warnings.
4278 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
4279 The returned value is now stored in *YY0. All callers changed.
4280 * src/output.c (merge_output): Adjust to the above change.
4282 2003-07-26 Paul Eggert <eggert@twinsun.com>
4284 * data/glr.c (YYASSERT): New macro.
4285 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
4286 yyresolveStates, yyprocessOneStack):
4287 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
4288 Derived from a suggestion by Frank Heckenbach.
4290 2003-07-25 Paul Eggert <eggert@twinsun.com>
4292 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
4293 for portability to K&R C (after ansi2knr, presumably). See
4294 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
4295 by Frank Heckenbach, though I have omitted the structure-initialization
4296 part of his glr-knr.diff patch since I recall that the Portable
4297 C Compiler didn't require that change.
4299 Let the user specify how to allocate and free memory.
4300 Derived from a suggestion by Frank Heckenbach in
4301 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
4302 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
4303 All uses of free, malloc, realloc changed to use these macros,
4304 and unnecessary casts removed.
4305 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
4307 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
4309 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
4310 use s.empty() rather than s == "" to test for empty string; see
4311 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
4314 2003-06-25 Akim Demaille <akim@epita.fr>
4316 * config/depcomp, config/install-sh: Update from masters.
4318 2003-06-20 Paul Eggert <eggert@twinsun.com>
4320 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
4321 and return properly parenthesized result.
4322 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
4323 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4324 Remove unnecessary parentheses from uses.
4325 * doc/bison.texinfo (Location Default Action): Describe the
4326 conventions for parentheses.
4328 2003-06-19 Paul Eggert <eggert@twinsun.com>
4330 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
4331 yyreportTree): Do not assume that size_t is the same width as int,
4332 when printing sizes. Print sizes using an unsigned format.
4333 Problem reported by Frank Heckenbach in
4334 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
4336 Port to Forte Developer 7 C compiler.
4337 * data/glr.c (struct YYLTYPE): If locations are not being used,
4338 declare a single dummy member, as empty structs do not conform
4340 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
4341 the Forte Developer 7 C compiler complains that end-of-loop
4342 code is not reached.
4344 2003-06-17 Paul Eggert <eggert@twinsun.com>
4346 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
4347 avoid warnings from picky compilers about redefinition of PARAMS.
4349 2003-06-17 Paul Eggert <eggert@twinsun.com>
4353 * NEWS: Document 1.875b.
4355 * lib/bbitset.h: Do not include config.h; that's the includer's job.
4356 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
4357 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
4358 Don't use 'index' in comments, as it's a builtin fn on some hosts.
4359 * lib/bitset_stats.c: Include gettext.h unconditionally, as
4360 per recent gettext manual's suggestion.
4361 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
4362 Use prototypes, not old-style definitions.
4363 * lib/lbitset.c (lbitset_unused_clear): Likewise.
4364 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
4365 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
4366 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

4369 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
4370 vbitset_or_and_cmp, vbitset_copy): Likewise.
4372 * lib/libiberty.h: Do not include config.h; that's the includer's job.
4373 Do not include <stdlib.h>.
4374 (PARAMS): Define unconditionally for C89.
4375 (ATTRIBUTE_NORETURN): Remove.
4376 (ATTRIBUTE_UNUSED): Define unconditionally.
4378 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
4379 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
4380 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
4381 * lib/vbitset.c, lib/vbitset.h: New files.
4382 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
4383 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
4386 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
4387 `How Can I Reset @code{yyparse}', since texinfo does not allow
4388 arbitrary @ in node names.
4390 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
4391 shouldn't be needed according to the gettext 0.12.1 documentation
4392 but which seem to be needed anyway: codeset.m4 glibc21.m4
4393 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
4394 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
4395 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
4397 * lib/.cvsignore: Add stdbool.h.
4398 * m4/.cvsignore: Add nls.m4, po.m4.
4400 Upgrade to CVS gnulib.
4401 * stdbool_.h: File renamed from stdbool.h.in.
4402 * configure.ac (AM_STDBOOL_H): Invoke this instead of
4404 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
4405 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
4406 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
4407 (MOSTLYCLEANFILES): New var.
4408 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
4409 (stdbool.h): New rule.
4410 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,

4412 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
4413 m4/quote.m4: Upgrade to today's gnulib.
4415 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
4416 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
4417 the tests right now.
4418 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4419 yyerror are declared before use; C99 requires this.
4421 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4423 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
4425 (yyrecoverSyntaxError): Correct the logic for setting and testing
4427 Correct comment on handling EOF.
4428 Allow states with only a default reduction, rather than failing
4429 (I can't quite reconstruct why these were not allowed before).
4431 Fixes to avoid problem that $-N rules in GLR parsers can cause
4432 buffer overruns, corrupting state.
4434 * src/output.c (prepare_rules): Output max_left_semantic_context
4436 * src/reader.h (max_left_semantic_context): New variable declaration.
4437 * src/scan-gram.l (max_left_semantic_context): Define.
4438 (handle_action_dollar): Update max_left_semantic_context.
4439 * data/glr.c (YYMAXLEFT): New definition.
4440 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
4441 (yyresolveAction): Ditto.
4443 Fixes to problems with location handling in GLR parsers reported by
4444 Frank Heckenbach (2003/06/05).
4446 * data/glr.c (YYLTYPE): Make trivial if locations not used.
4447 (YYRHSLOC): Add parentheses, and define only if locations used.
4448 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
4450 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
4451 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4453 * tests/cxx-type.at: Exercise location information; update tests
4454 to differentiate output with and without locations.
4455 Remove forward declarations of yylex and yyerror---caused errors
4456 because default YYLTYPE not yet defined.
4457 Change semantic actions to compute strings, rather than printing
4458 them directly (to test proper passing of semantics values). Change
4459 output to prefix notation and update test data and expected results.
4460 (yylex): Track locations.
4461 (stmtMerge): Return value rather than printing, and include arguments
4464 2003-06-03 Paul Eggert <eggert@twinsun.com>
4466 Avoid warnings generated by GCC 2.95.4 when Bison is
4467 configured with --enable-gcc-warnings.
4468 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
4469 yy::]b4_parser_class_name[::translate_,
4470 yy::Stack::operator[] (unsigned),
4471 yy::Stack::operator[] (unsigned) const,
4472 yy::Slice::operator[] (unsigned),
4473 yy::Slice::operator[] (unsigned) const):
4474 Rename local vars to avoid warnings.
4475 * tests/glr-regression.at (Improper handling of embedded actions
4476 and $-N in GLR parsers): Remove unused local variable from yylex.
4477 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4478 (void) as arg when not pure, since we now assume C89 when building
4479 Bison. Pacify GCC by using parameter.
4481 2003-06-02 Paul Eggert <eggert@twinsun.com>
4483 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4484 yy::Location::lines, yy::Location::columns): Rename arguments
4485 to avoid shadowing; this removes a warning generated by GCC 3.3.
4487 2003-06-01 Paul Eggert <eggert@twinsun.com>
4489 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4490 to g++, as GCC 3.3 complains if you do it.
4491 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4492 everything that WARNING_CFLAGS has, except omit warnings
4493 not suitable for C++.
4494 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4495 * tests/atlocal.in (CXXFLAGS): New var.
4496 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4498 Fix a GLR parser bug I reported in February; see
4499 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4500 The problem was that GLR parsers did not conform to the C standard,
4501 because actions like { $1 = $2 + $3; } expanded to expressions
4502 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4503 to a local variable. The C standard says that expressions
4504 like (var = f ()) + (var = f ()) have undefined behavior.
4505 Another problem was that GCC sometimes issues warnings that
4506 yyfill and its parameters are unused.
4508 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4510 (yyfill): New function.
4512 (yyuserAction): Change type of yynormal to bool, so that it matches
4513 the new yyfill signature. Mark it as possibly unused.
4516 Follow up on a bug I reported in February, where a Bison-generated
4517 parser can loop. Provide a test case and a fix for yacc.c. I
4518 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4519 The original bug report is in:
4520 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4522 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4523 macro's size was becoming unwieldy.
4524 (yyerrlab): Do not discard an empty lookahead symbol, as this
4525 might destroy garbage.
4526 (yyerrorlab): New label, with the old contents of YYERROR,
4527 plus the following change: pop the stack of rhs corresponding
4528 to the production that invoked YYERROR. That is how Yacc
4529 behaves, and POSIX requires this behavior.
4530 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4531 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4532 Define 'alarm' to do nothing if unistd.h is not available.
4533 Add a new rule "exp: '-' error;" to test the above change to
4534 data/yacc.c. Use 'alarm' to abort any test taking longer than
4535 10 seconds, as it's probably looping.
4536 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4537 Also, the new yacc.c generates two fewer diagnostics for an
4540 2003-05-24 Paul Eggert <eggert@twinsun.com>
4542 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4543 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4544 This fixes a problem reported by John Bowman when the Compaq/HP
4545 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4547 * data/yacc.c (union yyalloc): Likewise.
4548 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4550 Switch from 'int' to 'bool' where that makes sense.
4552 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,

4576 lbitset_xor_cmp): Likewise.
4577 * lib/bbitset.h: Include <stdbool.h>.
4578 (struct bitset_vtable): The following members now return bool, not

4611 * config/install-sh: Sync from automake 1.7.5.
4613 2003-05-14 Paul Eggert <eggert@twinsun.com>
4615 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4616 semicolon after a grammar declaration, in the interest of possible
4617 future changes to the Bison input language.
4618 Do not allow a stray semicolon at the start of the grammar.
4619 (rhses.1): Allow one or more semicolons after any rule, including
4620 just before "|" as required by POSIX.
4621 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4624 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4626 %parse-param support for lalr1.cc.
4628 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4629 b4_cc_constructor_calls, b4_cc_constructor_call,
4630 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4632 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4633 parse-param arguments.
4634 (yy::b4_parser_class_name): Declare instance variables to
4635 hold parse-param arguments.
4636 * tests/calc.at: s/value/semantic_value/ because value clashes
4637 with a member of yy::b4_parser_class_name. Adjust C++ code
4638 to handle %parse-param. Enable %parse-param test in C++.
4640 2003-05-12 Paul Eggert <eggert@twinsun.com>
4642 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4643 English a bit. Fix fclose typo. Change "const char" to "char
4644 const", and use ANSI C rather than K&R for "main". Suggest
4645 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4646 and suggest yy_switch_to_buffer.
4648 2003-05-05 Paul Eggert <eggert@twinsun.com>
4650 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4651 C89. This avoids a diagnostic on compilers that define __STDC__
4652 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4653 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4655 2003-05-03 Paul Eggert <eggert@twinsun.com>
4657 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):

4662 2003-04-29 Akim Demaille <akim@epita.fr>
4664 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4665 * src/getargs.c, src/getargs.h: here, as bool, not int.
4666 (nondeterministic_parser): New.
4667 * src/parse-gram.y, src/scan-gram.l: Support
4668 %nondeterministic-parser.
4669 * src/output.c (prepare): Use nondeterministic_parser instead
4670 of glr_parser where appropriate.
4671 * src/tables.c (conflict_row, action_row, save_row)
4672 (token_actions, token_actions, pack_vector): Ditto.
4674 2003-04-29 Akim Demaille <akim@epita.fr>
4676 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4678 2003-04-29 Akim Demaille <akim@epita.fr>
4680 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4681 with %pure-parser and %locations to exercise the patch from Yakov
4684 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4686 * data/yacc.c: (b4_lex_param): Corrected for the case where
4687 %lex-param is provided and %pure-parser isn't.
4689 2003-04-27 Paul Eggert <eggert@twinsun.com>
4691 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4692 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4693 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4694 if it is not defined.
4695 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4697 2003-04-26 Paul Eggert <eggert@twinsun.com>
4699 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4700 Declare to be of type suitable for the ninf value itself, not of
4701 type suitable for the corresponding table, since the latter might
4702 be unsigned but the ninf value might be negative. This fixes a
4703 bug reported by Alexandre Duret-Lutz in
4704 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4706 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4707 invokes it. We shouldn't invoke it twice because it will attempt
4708 to put error.o in the archive twice. This fixes a glitch reported
4709 by Martin Mokrejs in
4710 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4712 2003-04-21 Paul Eggert <eggert@twinsun.com>
4714 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4717 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4719 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4720 Fix obvious typo that results in uncompilable GLR parsers
4721 when both %pure-parser and %locations are used. (trivial change)
4723 2003-04-17 Paul Eggert <eggert@twinsun.com>
4725 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4726 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4727 Do not insert the expected token via unput, as this runs afoul
4728 of a POSIX-compatibility bug in flex 2.5.31.
4729 All uses changed to BEGIN the parent state,
4730 since we no longer insert the expected token via unput.
4731 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4732 that is no longer emitted after the above change.
4734 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4735 the first one. This change is from Paul Hilfinger, and it fixes
4736 regression reported by Werner Lemberg in
4737 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4739 (resolve_sr_conflict): Don't invoke state_errs_set
4740 unless one or more tokens have been explicitly made errors.
4741 Otherwise, the above change causes Bison to abort.
4743 * tests/existing.at (GNU pic Grammar): New test case, taken from
4746 2003-03-31 Akim Demaille <akim@epita.fr>
4748 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4750 2003-03-31 Akim Demaille <akim@epita.fr>
4752 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4755 2003-03-31 Akim Demaille <akim@epita.fr>
4757 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4758 From Paul Hilfinger.
4760 2003-03-29 Akim Demaille <akim@epita.fr>
4762 * m4/error.m4: Do not put under dynamic conditions some code which
4763 expansion is under static control.
4765 2003-03-29 Akim Demaille <akim@epita.fr>
4767 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4769 2003-03-29 Akim Demaille <akim@epita.fr>
4771 * doc/bison.texinfo (Strings are Destroyed): New.
4773 2003-03-13 Paul Eggert <eggert@twinsun.com>
4775 * .cvsignore: Add configure.lineno.
4776 * src/.cvsignore: Add yacc.
4777 * tests/.cvsignore: Add testsuite.log.
4778 * doc/fdl.texi: Sync with latest FSF version.
4780 2003-03-12 Paul Eggert <eggert@twinsun.com>
4782 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4783 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4784 cursor, instead of leaving it undefined. This fixes a bug
4785 reported by Tim Van Holder in
4786 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4787 * tests/input.at (Torturing the Scanner): Test the scanner on
4788 an empty input file, which was Tim Van Holder's test case.
4790 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4791 <sys/resource.h> can be included, include sys/time.h and
4792 sys/times.h first, if available. This works around the SunOS
4793 4.1.4 porting bug reported by Bruce Becker in
4794 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4796 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4797 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4800 Merge changes from gnulib. This was prompted because the CVS
4801 snapshot didn't build on Solaris 7 due to strnlen problems.
4803 These changes need to be merged back into gnulib:
4804 * lib/hash.c: Include <stdbool.h> unconditionally.
4805 * m4/onceonly.m4 (m4_quote): New macro.
4806 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4807 Quote AC_FOREACH variable-expansions properly.
4808 The 2003-01-03 obstack.h change also needs merging.
4809 {end of changes requiring merging}

4815 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
4816 New files, imported from gnulib.
4817 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
4820 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
4821 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current

4832 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
4833 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
4834 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
4835 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
4836 (jm_PREREQ_ARGMATCH): Remove.
4837 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
4838 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
4840 * src/system.h: Include <stdbool.h> unconditionally.
4842 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
4843 assuming at least C89 in the bitset code for some time now.
4845 2003-03-03 Akim Demaille <akim@epita.fr>
4849 2003-03-02 Akim Demaille <akim@epita.fr>
4851 * doc/bison.texinfo (Table of Symbols): Reactivate the
4852 documentation for %lex-param, and %parse-param.
4854 2003-03-02 Akim Demaille <akim@epita.fr>
4856 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4857 generate verbose error messages.
4858 Use the number of tokens as an upper bound in yytname, as it
4859 cannot be a non terminal.
4861 2003-03-02 Akim Demaille <akim@epita.fr>
4863 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4866 2003-03-02 Akim Demaille <akim@epita.fr>
4868 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
4869 Use them to exercise yycheck overrun.
4870 Based on Andrew Suffield's grammar.
4872 2003-03-02 Akim Demaille <akim@epita.fr>
4874 Create tests/local.at for Bison generic testing macros.
4876 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
4877 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
4879 * tests/calc.at (AT_CHECK_CALC): Adjust.
4880 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
4881 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
4882 * tests/local.at: here.

4884 Ignore the test if CXX is not functional.
4886 2003-03-01 Paul Eggert <eggert@twinsun.com>
4888 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
4889 not loc->end, since loc->end might contain garbage and this leads
4890 to undefined behavior on some platforms.
4891 (id_loc, token_start): Use (IF_LINTed) initial values that do not
4892 depend on *loc, so that the reader doesn't give the the false
4893 impression that *loc is initialized.
4894 (<INITIAL>"%%"): Do not bother setting code_start, since its value
4895 does not survive the return.
4897 2003-03-01 Akim Demaille <akim@epita.fr>
4899 * src/scan-gram.l (code_start): Always initialize it when entering
4900 into yylex, as SC_EPILOGUE is activated *before* the corresponding
4901 yylex invocation. An alternative would be making it static, but
4902 then it starts with the second %%'s beginning, instead of its end.
4904 2003-02-28 Paul Eggert <eggert@twinsun.com>
4906 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
4907 around a UnixWare 7.1.1 porting bug reported by John Hughes in
4908 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
4910 2003-02-26 Paul Eggert <eggert@twinsun.com>
4912 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
4913 Remove Sequent/Pyramid discussion (nobody uses them any more).
4914 Merge VMS and MS-DOS discussion; these ports may well be dead
4915 but let's keep mentioning them for now. Put <> around email
4916 addresses. Add copyright notice.
4918 2003-02-24 Paul Eggert <eggert@twinsun.com>
4920 * data/glr.c (yy_reduce_print): yylineno -> yylno,
4921 to avoid collision with flex use of yylineno.
4922 Problem reported by Bruce Lilly in
4923 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

4933 Suggested by Paul Eggert.
4935 2003-02-21 Akim Demaille <akim@epita.fr>
4937 * doc/bison.texinfo: Use "location" consistently to refer to @n,
4938 to avoid confusions with lalr1.cc's notion of Position.
4939 Suggested by Paul Eggert.
4941 2003-02-20 Akim Demaille <akim@epita.fr>
4943 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
4944 before initial_columns.
4945 (location.hh): Use consistent variable names when defining the
4947 Use "last" so that we subtract from Positions, not from unsigned.
4949 2003-02-20 Akim Demaille <akim@epita.fr>
4951 * data/lalr1.cc (position.hh): New subfile, including the extended
4952 and Doxygen'ed documentation of class Position.
4953 (location.hh): Use it.
4954 Document a` la Doxygen.
4955 With the help of Benoit Perrot.

4966 Activate more lalr1.cc tests.
4968 2003-02-19 Akim Demaille <akim@epita.fr>

4982 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
4983 error recovery, mixing with/without pops and discarding of the

4990 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
4991 * tests/testsuite.at (AT_COMPILE): Use them.

5152 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
5153 * tests/Makefile.am: Ditto.
5155 2003-01-28 Paul Eggert <eggert@twinsun.com>
5157 * data/lalr1.cc: Do not use @output_header_name@ unless
5158 b4_defines_flag is set. This fixes two bugs reported by
5160 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
5161 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
5163 2003-01-21 Paul Eggert <eggert@twinsun.com>
5165 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
5166 we don't need to worry about yyerrlab1 being reported as an
5167 "unused label" by non-GCC C compilers. The downside is that if
5168 locations are used then a couple of statements are duplicated each
5169 time YYERROR is invoked, but the upside is that the warnings
5171 (yyerrlab1): Move code to YERROR.
5172 (yyerrlab2): Remove. Change uses back to yyerrlab1.
5173 This reverts some of the 2002-12-27 change.
5175 2003-01-17 Paul Eggert <eggert@twinsun.com>
5177 * src/output.c (symbol_printers_output): Fix typo that led
5178 to core dump. Problem reported by Antonio Rus in
5179 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
5181 2003-01-13 Akim Demaille <akim@epita.fr>,
5182 Quoc Peyrot <chojin@lrde.epita.fr>,
5183 Robert Anisko <anisko_r@lrde.epita.fr>
5185 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
5186 when the stacks contain one element, as the loop would otherwise
5187 free the last state, and then use the top state (the one we just
5188 popped). This means that the initial elements will not be freed
5189 explicitly, as is the case in yacc.c; it is not a problem, as
5190 these elements have fake values.
5192 2003-01-11 Paul Eggert <eggert@twinsun.com>
5194 * NEWS: %expect-violations are now just warnings, reverting
5195 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
5196 bootstrapping problem reported by Matthias Klose; see
5197 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
5198 * src/conflicts.c (conflicts_print): Likewise.
5199 * tests/conflicts.at (%expect not enough, %expect too much,
5200 %expect with reduce conflicts): Likewise.
5201 * doc/bison.texinfo (Expect Decl): Document this. Also mention
5202 that the warning is enabled if the number of conflicts changes
5203 (not necessarily increases).
5205 * src/getargs.c (version): Update copyright year.
5207 2003-01-09 Akim Demaille <akim@epita.fr>
5209 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
5211 2003-01-08 Paul Eggert <eggert@twinsun.com>
5213 * Makefile.maint (WGETFLAGS):
5214 New macro, containing "-C off" to disable proxy caches.
5215 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
5216 (rel-check): Use $(WGET) instead of wget.
5218 2003-01-06 Paul Eggert <eggert@twinsun.com>
5220 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
5221 the GLR paper of Scott, Johnstone and Hussain.
5223 2003-01-04 Paul Eggert <eggert@twinsun.com>
5225 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
5226 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
5227 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
5228 (EXTRA_LIBRARIES): New var, for liby.a.
5229 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
5230 (EXTRA_SCRIPTS): New var, for yacc.
5232 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
5233 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
5234 Problem reported by Nelson H. F. Beebe.
5236 2003-01-03 Paul Eggert <eggert@twinsun.com>
5238 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
5239 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
5240 when compiling Bison 1.875's `bitset bset = obstack_alloc
5241 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
5243 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
5244 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
5245 grow to a huge size with typical invocation.
5247 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
5248 Use the pattern recommended by Autoconf 2.57, except also protect
5249 against double-definition.
5250 * src/system.h: Likewise.
5251 Portability issues reported by Nelson H. F. Beebe.
5253 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
5254 All uses changed. Provide a definition in both C and C++.
5255 (yytrue, yyfalse): Define even if defined (__cplusplus).
5257 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
5258 Reported by Nelson H. F. Beebe.
5260 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
5262 2003-01-02 Paul Eggert <eggert@twinsun.com>
5264 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
5265 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
5266 Bug reported by Nelson H. F. Beebe.
5268 2003-01-01 Paul Eggert <eggert@twinsun.com>
5272 2002-12-30 Paul Eggert <eggert@twinsun.com>
5274 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
5276 (<INITIAL>","): Here. This causes stray "," to be treated
5279 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
5280 last brace in braced code when not in Yacc mode, for compatibility
5281 with Bison 1.35. This resurrects the 2001-12-15 patch to
5284 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
5285 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
5287 2002-12-28 Paul Eggert <eggert@twinsun.com>
5289 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
5290 that of SYM's type. This fixes Debian bug 168069, reported by
5293 2002-12-28 Paul Eggert <eggert@twinsun.com>
5297 Switch back to the Yacc style of conflict reports, undoing some
5298 of the 2002-07-30 change.
5299 * doc/bison.texinfo (Understanding): Use Yacc style for
5300 conflict reports. Also, use new way of locating rules.
5301 * src/conflicts.c (conflict_report):
5302 Renamed from conflict_report_yacc, removing the old
5303 'conflict_report'. Translate the entire conflict report at once,
5304 so that we don't assume that "," has the same interpretation in
5306 (conflicts_output): Use Yacc-style conflict report for each state,
5307 instead of our more-complicated style.
5308 (conflicts_print): Use Yacc-style conflict report, except print
5309 the input file name when not emulating Yacc.
5310 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5311 Conflicted Reduction, %expect not enough, %expect too much,
5312 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
5313 * tests/existing.at (GNU Cim Grammar): Likewise.
5314 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
5316 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
5317 fatal): Don't invoke fflush; it's not needed and it might even be
5318 harmful for stdout, as stdout might not be open.
5319 * src/reduce.c (reduce_print): Likewise.
5321 2002-12-27 Paul Eggert <eggert@twinsun.com>
5323 Fix a bug where error locations were not being recorded correctly.
5324 This problem was originally reported by Paul Hilfinger in
5325 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
5327 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5328 top of the location stack's error locations.
5329 (yyerrlab): Set it. When discarding a token, push its location
5330 onto yylerrsp so that we don't lose track of the error's end.
5331 (yyerrlab1): Now is only the target of YYERROR, so that we can
5332 properly record the location of the action that failed. For GCC
5333 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5334 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5335 (yyerrlab2): New label, which yyerrlab now falls through to.
5336 Compute the error's location by applying YYLLOC_DEFAULT to
5337 the locations of all the symbols that went into the error.
5338 * doc/bison.texinfo (Location Default Action): Mention that
5339 YYLLOC_DEFAULT is also invoked for syntax errors.
5340 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5341 Error locations include the locations of all the tokens that were
5342 discarded, not just the last token.
5344 2002-12-26 Paul Eggert <eggert@twinsun.com>
5346 * src/files.c: Include quote.h.
5347 (compute_output_file_names): Warn if we detect conflicting
5348 outputs to the same file. This should catch the misunderstanding
5349 exemplified by Debian Bug 165349, reported by Bruce Stephens..
5351 * src/conflicts.c (conflicts_print): If the user specifies
5352 "%expect N", report an error if there are any reduce/reduce
5353 conflicts. This is what the manual says should happen.
5354 This fixes Debian bug 130890, reported by Anthony DeRobertis.
5355 * tests/conflicts.at (%expect with reduce conflicts): New test.
5357 Don't use m4_include on relative file names, as it doesn't work as
5358 desired if there happens to be a file with that name under ".".
5360 * m4sugar/version.m4: Remove; it was included but it wasn't used.
5361 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
5362 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
5363 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
5364 * src/output.c (output_skeleton): Use full path names when
5365 specifying a file to include; don't rely on include path, as
5366 it's unreliable when the working file contains a file with
5369 2002-12-25 Paul Eggert <eggert@twinsun.com>
5371 Remove obsolete references to bison.simple and bison.hairy.
5372 Problem mentioned by Aubin Mahe in
5373 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
5374 * data/glr.c: Comment fix.
5375 * doc/bison.1: Remove references. Also, mention "yacc".
5377 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
5380 * src/parse-gram.y (declaration): Use enum "report_states" rather
5381 than its numeric value 1.
5383 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
5384 opening a new one. This fixes Debian bug 165349, reported by
5387 2002-12-24 Paul Eggert <eggert@twinsun.com>
5391 * Makefile.maint (cvs-update): Don't assume that the shell
5392 supports $(...), as Solaris sh doesn't.
5394 * src/parse-gram.y (lloc_default): Remove test for empty
5395 nonterminals at the end, since it didn't change the result.
5397 2002-12-24 Paul Eggert <eggert@twinsun.com>
5399 If the user does not define YYSTYPE as a macro, Bison now declares it
5400 using typedef instead of defining it as a macro. POSIX requires this.
5401 For consistency, YYLTYPE is also declared instead of defined.
5403 %union directives can now have a tag before the `{', e.g., the
5404 directive `%union foo {...}' now generates the C code
5405 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5406 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5407 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5408 instead of `yyltype'.
5410 `yystype' and `yyltype' are now obsolescent macros instead of being
5411 typedefs or tags; they are no longer documented and will be
5412 withdrawn in a future release.
5414 * data/glr.c (b4_location_type): Remove.
5415 (YYSTYPE): Renamed from yystype.
5416 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5417 (struct YYLTYPE): Renamed from struct yyltype.
5418 (YYLTYPE): Renamed from yyltype.
5419 (yyltype, yystype): New (and obsolescent) macros,
5420 for backward compatibility.
5421 * data/yacc.c: Likewise.
5423 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5424 does not specify a union tag. This is for compatibility with
5427 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5428 const *, since it is now modified by stripping surrounding { }.
5429 (current_braced_code): Remove.
5430 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5431 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5432 trailing " {...}". Now of type <chars>.
5433 (grammar_declaration): Adjust to bundled tokens.
5434 (code_content): Remove; stripping is now done by add_param.
5435 (print_token_value): Print contents of bundled tokens.
5436 (token_name): New function.
5438 * src/reader.h (braced_code, current_braced_code): Remove.
5439 (token_name): New decl.
5441 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5442 token_type, not braced_code code_kind. All uses changed.
5443 (SC_PRE_CODE): New state, for scanning after a keyword that
5444 has (or usually has) an immediately-following braced code.
5445 (token_type): New local var, to keep track of which token type
5446 to return when scanning braced code.
5447 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5448 <INITIAL>"%parse-param", <INITIAL>"%printer",
5449 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5450 instead of returning a token type immediately.
5451 (<INITIAL>"{"): Set token type.
5452 (<SC_BRACED_CODE>"}"): Use it.
5453 (handle_action_dollar, handle_action_at): Now returns bool
5454 indicating success. Fail if ! current_rule; this prevents a core dump.
5455 (handle_symbol_code_dollar, handle_symbol_code_at):
5456 Remove; merge body into caller.
5457 (handle_dollar, handle_at): Complain in invalid contexts.
5459 * NEWS, doc/bison.texinfo: Document the above.
5460 * NEWS: Fix years and program names in copyright notice.
5462 2002-12-17 Paul Eggert <eggert@twinsun.com>
5464 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5465 Reporting, Table of Symbols): Omit mentions of %lex-param and
5466 %parse-param from the documentation for now.
5468 2002-12-15 Paul Eggert <eggert@twinsun.com>
5470 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5471 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5472 lookahead symbol, and which sets yychar in parser actions) and it
5473 disagreed with the Bison documentation. Bug
5474 reported by Andrew Walrond.
5476 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5477 as the caller now does that.
5478 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5479 (YYEMPTY): Parenthesize right hand side, since others use it.
5480 (yyparse): Don't assume that our generated code is the only code
5483 2002-12-13 Paul Eggert <eggert@twinsun.com>
5487 POSIX requires a "yacc" command.
5488 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
5489 (MOSTLYCLEANFILES): Add yacc.
5491 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
5492 as an alias for bison y.
5494 * po/LINGUAS: Add da.
5496 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
5497 problem with latest <getopt.h>.
5498 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
5500 * doc/fdl.texi: Upgrade to 1.2.
5501 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
5502 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
5503 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
5505 * config/install-sh: Sync with autotools.
5507 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
5508 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5509 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
5510 locations are requested.
5511 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
5512 locations are requested.
5514 2002-12-12 Paul Eggert <eggert@twinsun.com>
5516 Remove unportable casts and storage allocation tricks.
5517 While we're at it, remove almost all casts, since they
5518 usually aren't needed and are a sign of trouble.
5520 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5522 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5523 the pointer DSET returned by malloc; this isn't portable.
5524 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
5525 Similarly for DERIVES.
5526 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
5527 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
5528 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
5530 * src/derives.c (derives_compute): Do not bother invoking
5531 int_of_rule_number, since rule numbers are integers.
5533 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
5534 rather than XMALLOC (char, N).
5536 * src/files.c (filename_split): Rewrite to avoid cast.
5538 * src/gram.h (symbol_number_as_item_number,
5539 item_number_as_symbol_number, rule_number_as_item_number,
5540 item_number_as_rule_number):
5541 Now inline functions rather than macros, to avoid casts.
5542 * src/state.h (state_number_as_int): Likewise.
5543 * src/tables.c (state_number_to_vector_number,
5544 symbol_number_to_vector_number): Likewise.
5546 * src/gram.h (int_of_rule_number): Remove; no longer used.
5548 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
5549 since the resulting storage is always stored into.
5551 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
5554 * src/muscle_tab.c (muscle_m4_output):
5555 Now inline. Return bool, not int.
5556 * src/state.c (state_compare): Likewise.
5557 * src/symtab.c (symbol_check_defined,
5558 symbol_check_alias_consistency, symbol_pack, symbol_translation,
5559 hash_compare_symbol, hash_symbol):
5561 * src/uniqstr.c (uniqstr_print): Likewise.
5562 * src/muscle_tab.c (muscle_m4_output_processor):
5563 New function, to avoid casts.
5564 * src/state.c (state_comparator, stage_hasher): Likewise.
5565 * src/symtab.c (symbol_check_defined_processor,
5566 symbol_check_alias_consistency_processor, symbol_pack_processor,
5567 symbol_translation_processor, hash_symbol_comparator,
5568 hash_symbol_hasher): Likewise.
5569 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5570 * src/muscle_tab.c (muscles_m4_output):
5571 Use new functions instead of casting old functions unportably.
5572 * src/state.c (state_hash_new): Likewise.
5573 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5574 symbols_token_translations_init):
5576 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5578 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5579 var instead of casting to long, to avoid casts.
5580 (prepare_states): Use MALLOC rather than alloca, so that we don't
5581 have to worry about alloca.
5582 * src/state.c (state_hash_lookup): Likewise.
5584 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5585 local var instead of casting to unsigned char, to avoid casts.
5587 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
5588 STATE_ALLOC): Remove.
5589 (transitions_new, errs_new, reductions_new, state_new): Use malloc
5590 rather than calloc, and use offsetof to avoid allocating slightly
5592 (state_new): Initialize all members.
5594 * src/state.c (state_hash): Use unsigned accumulator, not signed.
5596 * src/symtab.c (symbol_free): Remove; unused.
5597 (symbol_get): Remove cast in lhs of assignment.
5598 (symbols_do): Now static. Accept generic arguments, not
5599 hashing-related ones.
5601 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
5602 (symbol_processor): Remove.
5603 (symbols_do): Remove decl; now static.
5605 * src/system.h (alloca): Remove; decl no longer needed.
5606 (<stddef.h>): Include, for offsetof.
5607 (<inttypes.>, <stdint.h>): Include if available.
5608 (uintptr_t): New type, if system lacks it.
5609 (CALLOC, MALLOC, REALLOC): New macros.
5610 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5613 * src/tables.c (table_size): Now int, to pacify GCC.
5614 (table_grow, table_ninf_remap): Use signed table size.
5615 (save_row): Don't bother initializing locals when not needed.
5616 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
5617 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
5619 * src/vcg.h: Correct misspellings.
5621 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
5624 * src/getargs.c (getargs): Don't assume EOF == -1.
5626 2002-12-09 Paul Eggert <eggert@twinsun.com>
5628 Change identifier spellings to avoid collisions with names
5629 that are reserved by POSIX.
5631 Don't use names ending in _t, since POSIX reserves them.
5632 For consistency, remove _e and _s endings -- they're weren't
5633 needed to remove ambiguity. All uses changed.
5634 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5635 turn was just renamed from struniq_t.

5709 value_t_as_yystype -> value_as_yystype.
5711 Don't include <errno.h> in the mainstream code, since it
5712 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5713 * lib/get-errno.c, lib/get-errno.h: New files.
5714 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
5716 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

5722 (handle_action_dollar, handle_action_at): Likewise.
5723 * src/system.h: Do not include <errno.h>.
5724 (TAB_EXT): Renamed from EXT_TAB.
5725 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
5727 Avoid str[a-z]*, since <string.h> reserves that name space.
5728 Change all instances of "struniq" in names to "uniqstr", and
5729 likewise for "STRUNIQ" and "UNIQSTR".
5730 * src/uniqstr.c: Renamed from src/struniq.c.

5768 * lib/timevar.h (timevar_report): New decl.
5769 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5772 Sort include-file uses.
5774 Reorder all include files under src to be in the order "system.h".
5775 then the ../lib include files in angle brackets (alphabetized),
5776 then the . include files in double-quotes (alphabetized). Fix
5777 dependency breakages encountered in this process, as follows:
5778 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5779 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5780 * src/state.h: Include "symtab.h".
5782 2002-12-08 Paul Eggert <eggert@twinsun.com>
5784 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5785 since this causes problems when __file__ contains character
5786 sequences like "@" that are treated specially by src/scan-skel.l.
5787 Instead, just use the file's basename. This fixes the bug
5788 reported by Martin Mokrejs in
5789 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5791 2002-12-06 Paul Eggert <eggert@twinsun.com>
5793 Add support for rules that do not have trailing semicolons, as
5794 POSIX requires. Improve the quality of locations in Bison
5797 * src/location.c: Include <quotearg.h>.
5798 (empty_location): Now const.
5799 (location_print): New function. Follow the recommendation of the
5800 GNU Coding Standards for locations that span file boundaries.
5801 * src/location.h: Do not include <quotearg.h>; no longer needed.
5802 (boundary): New type.
5803 (location_t): Use it. This allows locations to span file boundaries.
5804 All member uses changed: file -> start.file or end.file (as needed),
5805 first_line -> start.line, first_column -> start.column,
5806 last_line -> end.line, last_column -> end.column.
5807 (equal_boundaries): New function.
5808 (LOCATION_RESET, LOCATION_STEP): Remove.
5809 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5810 (empty_location): Now const.
5811 (location_print): New decl.
5812 * src/parse-gram.y (lloc_default): New function, which handles
5813 empty locations more accurately.
5814 (YYLLOC_DEFAULT): Use it.
5815 (%token COLON): Remove.
5816 (%token ID_COLON): New token.
5818 (declarations, rules): Remove trailing semicolon.
5819 (declaration, rules_or_grammar_declaration):
5820 Allow empty (";") declaration.
5821 (symbol_def): Remove empty actions; no longer needed.

5824 * src/reader.h: Include location.h.
5825 (scanner_cursor): New decl.
5826 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
5828 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
5830 (STEP): Remove. No longer needed, now that adjust_location does
5831 the work. All uses removed.
5832 (scanner_cursor): New var.
5833 (adjust_location): Renamed from extend_location. It now sets
5834 *loc and adjusts the scanner cursor. All uses changed.
5835 Don't bother testing for CR.
5836 (handle_syncline): Remove location arg; now updates scanner cursor.
5837 All callers changed.
5838 (unexpected_end_of_file): Now accepts start boundary of token or
5839 comment, not location. All callers changed. Update scanner cursor,
5841 (SC_AFTER_IDENTIFIER): New state.
5842 (context_state): Renamed from c_context. All uses changed.
5843 (id_loc, code_start, token_start): New local vars.
5844 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5845 processing of Yacc white space and equivalents here.
5846 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5847 instead of returning ID immediately, since we need to search for
5849 (<INITIAL>"'", "\""): Save token_start.
5850 (<INITIAL>"%{", "{", "%%"): Save code_start.
5851 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5852 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5853 BEGIN context_state at end, not INITIAL.
5854 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5855 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5856 Return correct token start.
5857 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5858 the start of a character, string or multiline comment is found.
5859 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5860 Reduction): Adjust reported locations to match the more-precise
5861 results now expected.
5862 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5863 * tests/reduce.at (Useless Rules, Reduced Automaton,
5864 Underivable Rules): Likewise.
5865 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5866 or "|"' now that so many other tokens are allowed by the new grammar.
5868 * src/complain.h (current_file): Remove duplicate decl;
5869 current_file is now owned by files.h.
5870 * src/complain.c, src/scan-gram.l: Include files.h.
5872 2002-12-06 Paul Eggert <eggert@twinsun.com>
5874 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
5875 promotes to int; it might be unsigned int.
5876 * data/yacc.c (yy_reduce_print): Likewise.
5878 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
5879 be #defined in the prologue, not in the Bison declarations.
5880 This fixes Debian Bug 102878, reported by Shaul Karl.
5882 2002-12-02 Paul Eggert <eggert@twinsun.com>
5884 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
5885 * lib/strtoul.c: New file, from gnulib.
5886 This fixes a porting bug reported by Peter Klein in
5887 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
5889 2002-11-30 Paul Eggert <eggert@twinsun.com>
5891 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
5892 and put only a forward declaration in the prologue. This is for
5893 consistency with the other scanner helper functions.
5895 Type clashes now generate warnings, not errors, since it
5896 appears that POSIX may allow some grammars with type clashes.
5897 * src/reader.c (grammar_current_rule_check): Warn about
5898 type clashes instead of complaining.
5899 * tests/input.at (Type Clashes): Expect warnings, not complaints.
5901 Add Yacc library, since POSIX requires it.
5902 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
5903 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
5904 * lib/main.c, lib/yyerror.c: New files.
5906 gram_error can be static; it need not be extern.
5907 * src/reader.h (gram_error): Remove decl.
5908 * src/parse-gram.y (gram_error): Now static. Add static decl.
5909 (print_token_value): Omit parameter names from forward decl,
5912 2002-11-29 Paul Eggert <eggert@twinsun.com>
5914 * doc/bison.texinfo: Emphasize that yylex and yyerror must
5915 be declared before being used. E.g., one should typically
5916 declare them in the prologue. Use GNU coding style in examples.
5917 Put "const" consistently after the type it modifies. Mention
5918 that C99 supports "inline". Mention that yyerror traditionally
5921 %parse-param and %lex-param now take just one argument, the
5922 declaration; the argument name is deduced from the declaration.
5924 * doc/bison.texinfo (Parser Function, Pure Calling, Error
5925 Reporting, Table of Symbols): Document this.
5926 * src/parse-gram.y (add_param): New function.
5928 (declaration): Implement new rule for %parse-param and %lex-param.
5929 * src/scan-gram.l: "," now elicits a warning, rather than being
5930 a token; this is more compatible with byacc.
5931 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
5933 2002-11-27 Paul Eggert <eggert@twinsun.com>
5935 Rename identifiers to avoid real and potential collisions.
5937 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
5938 to avoid collision with lex macro described by Bruce Lilly in
5939 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5940 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
5941 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
5942 * src/parse-gram.y (print_token_value): Renamed from yyprint.
5944 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
5945 The name "yycontrol" violates the name space rules, and this stuff
5946 wasn't being used anyway.
5947 (input): Remove action; this stuff wasn't being used.
5948 (gram_error): Rename local variable yylloc -> loc.
5949 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
5950 (YY_DECL): Don't use "yy" at start of local variables.
5951 All uses changed, e.g., yylloc -> loc.
5952 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
5953 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
5954 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
5955 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
5957 * src/parse-gram.y (gram_error): loc is now const *.
5958 * src/reader.h (gram_error): Likewise.
5960 2002-11-24 Paul Eggert <eggert@twinsun.com>
5964 * tests/actions.at (Actions after errors): Use an output format
5965 more similar to that of the Printers and Destructors test.
5966 Test the position of the ';' token too.
5967 (Printers and Destructors): Likewise.
5968 (Printers and Destructors: %glr-parser): Remove for now, to avoid
5969 unnecessarily alarming people when the test fails.
5971 * data/yacc.c (yyerrlab1): Move this label down, so that the
5972 parser does not discard the lookahead token if the user code
5973 invokes YYERROR. This change is required for POSIX conformance.
5975 * lib/error.c: Sync with gnulib.
5977 2002-11-22 Paul Eggert <eggert@twinsun.com>
5979 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
5980 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
5981 * lib/xmalloc.c: Likewise.
5983 2002-11-20 Paul Eggert <eggert@twinsun.com>
5985 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
5987 2002-11-20 Paul Eggert <eggert@twinsun.com>
5989 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
5990 should use `if (! x) abort ();' rather than `assert (x);', and
5991 anyway it's one less thing to worry about configuring.
5993 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
5994 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
5995 and replace all instances of assert with abort.

5997 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
5999 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
6000 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
6001 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
6002 hash_find_entry, hash_rehash, hash_insert): Likewise.
6003 * src/conflicts.c (resolve_sr_conflict): Likewise.
6004 * src/lalr.c (set_goto_map, map_goto): Likewise.
6005 * src/nullable.c (nullable_compute): Likewise.
6006 * src/output.c (prepare_rules, token_definitions_output): Likewise.
6007 * src/reader.c (packgram, reader): Likewise.

6009 state_reduction_find): Likewise.
6010 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
6011 symbol_pack): Likewise.
6012 * src/tables.c (conflict_row, pack_vector): Likewise.
6013 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
6014 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
6015 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
6016 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
6018 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
6019 (ARGMATCH_CONSTRAINT): New macro.
6020 (ARGMATCH_ASSERT): Use it.
6022 * src/system.h (verify): New macro.
6023 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
6025 * src/tables.c (tables_generate): Likewise.
6027 * src/struniq.c (struniq_assert): Now returns void, and aborts
6028 if the assertion is false.
6029 (struniq_assert_p): Remove.
6030 * src/struniq.h: Likewise.
6032 2002-11-18 Paul Eggert <eggert@twinsun.com>
6034 * data/glr.c (yygetLRActions): Replace `yyindex' with
6035 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
6036 This fixes the regression with Sun ONE Studio 7 cc that I reported in
6037 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
6039 2002-11-18 Akim Demaille <akim@epita.fr>
6041 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
6043 From Tim Van Holder.
6045 2002-11-17 Paul Eggert <eggert@twinsun.com>
6047 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
6048 to "SyntaxError" for consistency with my 2002-11-15 change.
6050 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
6051 not define to {}, since this breaks the common use of `YYDPRINTF
6052 ((...));' if a single statement is desired (e.g. before `else').
6053 Work around GCC warnings by surrounding corresponding calls with
6055 (yyhasResolvedValue): Remove unused function.
6056 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
6058 (yyreportSyntaxError): Renamed from yyreportParseError.
6059 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
6061 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
6062 extern when possible. Remove unused initializations.
6064 2002-11-16 Akim Demaille <akim@epita.fr>
6066 Augment the similarity between GLR and LALR traces.
6068 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
6069 (YY_REDUCE_PRINT): New.
6070 (yyparse): Use them.
6071 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
6073 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
6074 state reached after the reduction/recovery, since...
6075 (yyparse, yyprocessOneStack): Report the state we are entering in.
6077 2002-11-16 Akim Demaille <akim@epita.fr>
6079 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
6080 Add support for --trace=skeleton.
6081 * src/scan-skel.l: %option debug.
6082 Scan strings of non-@ or \n instead of character by character.
6083 (scan_skel): Handle trace_skeleton.
6085 (@output_parser_name@, @output_header_name@): ``Restore'' their
6086 support (used to be M4 macros).
6087 * data/yacc.c: Quote larger chunks, a la glr.c.
6088 * data/lalr1.cc: Likewise.
6089 The header guards are no longer available, so use some other
6090 string than `YYLSP_NEEDED'.
6092 2002-11-16 Akim Demaille <akim@epita.fr>
6094 Make the ``Printers and Destructors'' test more verbose, taking
6095 `yacc.c''s behavior as (possibly wrong) reference.
6097 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
6098 instead of fprint on stdout.
6099 Set and report the last_line of the symbols.
6100 Consistently display values and locations.
6102 2002-11-16 Paul Eggert <eggert@twinsun.com>
6104 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
6106 2002-11-15 Paul Eggert <eggert@twinsun.com>
6108 * tests/actions.at (Actions after errors): New test case.
6110 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
6111 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
6112 tests/action.at, tests/calc.at, tests/conflicts.at,
6113 tests/cxx-type.at, tests/regression.at:
6114 "parse error" -> "syntax error" for POSIX compatibility.
6115 "parsing stack overflow..." -> "parser stack overflow" so
6116 that code matches Bison documentation.
6118 2002-11-15 Akim Demaille <akim@epita.fr>
6120 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
6121 take two BRACED_CODE, not two string_content.
6122 Free the scanner's obstack when we are done.
6123 (code_content): New.
6124 * tests/calc.at: Adjust.
6125 * doc/bison.texinfo: Adjust.
6126 Also, make sure to include the `,' for these declarations.
6128 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
6130 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
6131 definition; avoids potential autoreconf problems.
6133 2002-11-15 Akim Demaille <akim@epita.fr>
6135 Always check the value returned by yyparse.
6137 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
6138 returned by yyparse.

6142 returned by yyparse.
6144 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6146 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
6149 2002-11-14 Paul Eggert <eggert@twinsun.com>
6151 * src/output.c (output_skeleton): Call xfopen instead of
6152 duplicating xfopen's body.
6154 Fix bugs reported by Nelson H. F. Beebe in
6155 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
6157 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
6158 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
6159 Group compiler. Instead, use "$CC -E bar.c". Include the .h
6160 file twice in the grammar, as an extra check.
6162 * tests/input.at (Torturing the Scanner): Surround the
6163 backslash-newline tests with "#if 0", to make it less likely that
6164 we'll run into compiler bugs. Bring back solitary \ inside
6165 comment, but add a closing comment to work around HP C bug. Don't
6166 test backslash-newline in C character constant.
6168 2002-11-14 Akim Demaille <akim@epita.fr>
6170 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
6171 status of the compiler.
6172 Calling `exit 1' is no longer needed.
6173 Reported by Nelson H. F. Beebe.
6175 2002-11-14 Akim Demaille <akim@epita.fr>
6177 * tests/atlocal.in (CPPFLAGS): We have config.h.

6180 * tests/actions.at, tests/calc.at, tests/conflicts.at,
6181 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
6182 * tests/regression.at, tests/torture.at: Use them for all the
6183 grammars that are to be compiled.
6184 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
6185 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
6186 * doc/bison.texinfo (GLR Parsers): Document `inline'.
6188 2002-11-14 Akim Demaille <akim@epita.fr>
6190 * doc/bison.texinfo: Various formatting changes (alignments in
6191 samples, additional @group/@end group, GCS in samples.
6192 Use @deffn instead of simple @table to define the directives,
6193 macros, variables etc.
6195 2002-11-13 Paul Eggert <eggert@twinsun.com>
6197 Fix some bugs reported by Albert Chin-A-Young in
6198 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
6200 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
6201 -o c"; the HP C compiler chatters during compilation.
6202 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
6203 * tests/headers.at (export YYLTYPE): Likewise.
6205 * tests/input.at (Torturing the Scanner): Remove lines containing
6206 solitary backslashes, as they tickle a bug in the HP C compiler.
6208 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
6209 comments, since they're not portable. Use GNU coding style.
6211 2002-11-13 Akim Demaille <akim@epita.fr>
6213 * data/yacc.c: Leave bigger chunks of quoted text.
6214 (YYDSYMPRINTF): New.
6215 Use it to report symbol activities.
6216 * data/glr.c (YYDSYMPRINTF): New.
6219 2002-11-12 Paul Eggert <eggert@twinsun.com>
6223 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
6224 (yyglrReduce): Return yyok, not 0.
6225 This should avoid the enumerated-type warnings reported
6226 by Nelson H. F. Beebe in
6227 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
6229 * lib/bbitset.h (BITSET_INLINE): Remove.
6230 * lib/bitset.h [! BITSET_INLINE]: Remove.
6231 (bitset_set, bitset_reset, bitset_test): Rename local vars
6232 to avoid shadowing warnings by GCC.
6234 * data/glr.c (inline): Remove #define. It's the user's
6235 responsibility to #define it away, just like 'const'.
6236 This fixes one of the bugs reported by Nelson H. F. Beebe in
6237 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
6239 * Makefile.maint (po-check): Scan .l and .y files instead of the
6240 .c and the .h files that they generate. This fixes the bug
6241 reported by Tim Van Holder in:
6242 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
6243 Look for N_ as well as for _. Try to avoid matching #define for
6245 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
6246 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
6247 * src/scan-gram.l: Revamp regular expressions so that " and '
6248 do not confuse xgettext.
6250 * src/struniq.h (struniq_new): Do not declare the return type
6251 to be 'const'; this violates the C standard.
6252 * src/struniq.c (struniq_new): Likewise.
6254 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
6256 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
6257 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
6260 2002-11-12 Akim Demaille <akim@epita.fr>
6262 * Makefile.maint: Sync with Autoconf:

6279 2002-11-12 Akim Demaille <akim@epita.fr>
6281 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
6282 Use it to test the GLR parser.
6284 2002-11-12 Akim Demaille <akim@epita.fr>
6286 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
6288 * data/glr.c (yystos): New.
6289 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
6291 (yyval): Don't define it, it is handled via M4.
6292 (yyrecoverParseError): Free verbosely the discarded symbols.
6293 * data/yacc.c (yysymprint): Remove, rather...
6294 (b4_yysymprint_generate): invoke.
6295 * data/c.m4 (b4_yysymprint_generate): New.
6296 Accept pointers as arguments, as opposed to the version from
6298 (b4_yydestruct_generate): Likewise.
6299 * tests/cations.at (Printers and Destructors): Use Bison directives
6300 instead of CPP macros.
6301 Don't rely on internal details.
6303 2002-11-12 Akim Demaille <akim@epita.fr>
6305 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
6306 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
6307 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
6308 it against YYEMPTY and so forth), work on yytoken (i.e., set
6309 it to YYEMPTY etc.).
6310 (yydestruct): Replace with a b4_yydestruct_generate invocation.
6311 (b4_symbol_actions): Remove.
6312 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
6313 for 0, end-of-input.
6315 2002-11-12 Akim Demaille <akim@epita.fr>
6317 * doc/bison.texinfo (Destructor Decl): New.
6319 2002-11-12 Akim Demaille <akim@epita.fr>
6321 * src/tables.c (tables_generate): Use free for pointers that
6322 cannot be NULL, not XFREE.
6323 (pack_vector): Use assert, not fatal, for bound violations.
6324 * src/state.c (state_new): Likewise.
6325 * src/reader.c (reader): Likewise.
6326 * src/lalr.c (set_goto_map): Likewise.
6327 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
6330 2002-11-12 Akim Demaille <akim@epita.fr>
6332 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
6334 * src/scan-gram.l (last_string): Is global to the file, not to
6336 * src/parse-gram.y (input): Don't append the epilogue here,
6337 (epilogue.opt): do it here, and free the scanner's obstack.
6338 * src/reader.c (epilogue_set): Rename as...
6339 (epilogue_augment): this.
6340 * data/c.m4 (b4_epilogue): Defaults to empty.
6342 2002-11-12 Akim Demaille <akim@epita.fr>
6344 * src/getargs.c (long_options): Remove duplicates.

6383 Don't free the input file name.
6385 2002-11-12 Akim Demaille <akim@epita.fr>
6387 * src/symtab.c (symbol_free): Remove dead deactivated code:

6398 2002-11-11 Paul Eggert <eggert@twinsun.com>
6400 Revamp to fix many (but not all) of the C- and M4-related quoting
6401 problems. Among other things, this fixes the Bison bug reported
6402 by Jan Hubicka when processing the Bash grammar; see:
6403 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6405 Use new @ escapes consistently. Represent brackets with @{ and @}
6406 rather than @<:@ and @:>@, since this works a bit better with dumb
6407 editors like vi. Represent @ with @@, since @ is now consistently
6408 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6409 __ofile__, to avoid unexpected expansions. Similarly, use @output
6410 rather than #output.
6412 * data/c.m4 (b4_copyright): Omit file name from comment, since
6413 the file name could contain "*/".
6414 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6415 be quoted. All uses changed.
6417 * data/glr.c: Use new @ escapes consistently.
6418 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6419 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6420 Remove, since they couldn't handle arbitrary characters in file
6422 * data/lalr1.cc: Likewise.
6423 * data/yacc.c: Likewise.
6425 * src/files.c (output_infix): Remove; all uses removed.
6426 * src/files.h: Likewise.
6428 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6429 mishandled funny characters in file names, and anyway it isn't
6431 * data/yacc.c: Likewise.
6432 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6434 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6435 * data/yacc.c: Likewise.
6437 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6439 (muscle_init): Quote filename as a C string.
6440 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6441 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6442 * src/output.c (escaped_file_name_output): New function.
6443 (prepare_symbols): Quote tokens for M4.
6444 (prepare): Don't insert output_infix, output_prefix,
6445 output_parser_name, output_header_name; this is now down by scan-skel.
6446 Insert skeleton as a C string.
6448 * src/output.c (user_actions_output, symbol_destructors_output,
6449 symbol_printers_output): Quote filenames for C and M4.
6450 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6452 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
6453 escapes other than \\ and \'; this simplifies the code.
6454 (<SC_STRING>): Likewise, for \\ and \".
6455 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6456 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6457 Use new escapes @{ and @} for [ and ].
6459 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6460 them with auto vars.
6461 Switch to new escape scheme, where @ is the escape character uniformly.
6462 Abort if a stray escape character is found. Avoid unbounded input
6463 buffer when parsing non-escaped text.
6465 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6466 __oline__, #output, $@, and @{ do not have unintended meanings.
6468 2002-11-09 Paul Eggert <eggert@twinsun.com>
6470 Fix the test failure due to GCC warnings described in
6471 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6472 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6473 evaluate to 0 if it's impossible for NINF to be in the respective
6475 (yygetLRActions, yyrecoverParseError): Use them.
6477 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6478 counted in the token inserted at end of file. Now takes
6479 location_t *, not location_t, so that the location can be
6480 adjusted. All uses changed.
6482 * tests/regression.at (Invalid inputs): Adjust wording in
6483 diagnostic to match the new behavior.
6485 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6486 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6487 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6488 abort ();'. This reduces the runtime of the "Many lookaheads"
6489 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
6492 2002-11-07 Paul Eggert <eggert@twinsun.com>
6494 * src/parse-gram.y (CHARACTER): Remove unused token.
6497 * src/scan-gram.l: Remove stack option. We no longer use the
6498 stack, since the stack was never deeper than 1; instead, use the
6499 new auto var c_context to record the stacked value.
6501 Remove nounput option. At an unexpected end of file, we now unput
6502 the minimal input necessary to end cleanly; this simplifies the
6505 Avoid unbounded token sizes where this is easy.
6507 (unexpected_end_of_file): New function.
6508 Use it to systematize the error message on unexpected EOF.
6509 (last-string): Now auto, not static.
6510 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
6511 (scanner_last_string_free): Remove; not used.
6512 (percent_percent_count): Move decl to just before use.
6513 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
6514 not the (never otherwised-used) CHARACTER.
6516 2002-11-07 Akim Demaille <akim@epita.fr>
6518 Let yyerror always receive the msg as last argument, so that
6519 yyerror can be variadic.
6521 * data/yacc.c (b4_yyerror_args): New.
6522 Use it when calling yyerror.
6523 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
6524 Use it when calling yyerror.
6525 * doc/bison.texinfo (Error Reporting): Adjust.

6527 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
6529 2002-11-06 Akim Demaille <akim@epita.fr>
6531 #line should have quoted strings.
6532 Ideally, this should be done by m4_quotearg.
6534 * src/scan-skel.l: Include quotearg.h.
6536 * src/output.c (symbol_printers_output)
6537 (symbol_destructors_output): Quote the file name.
6539 2002-11-06 Akim Demaille <akim@epita.fr>
6541 * tests/regression.at (Invalid inputs): Adjust to the recent
6544 2002-11-06 Akim Demaille <akim@epita.fr>
6547 Reported by Jim Kent.
6549 * data/c.m4 (b4_syncline): New.
6550 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
6551 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.

6585 as POSIX 1003.1-2001 requires.
6586 * src/system.h (IF_LINT): New macro, taken from coreutils.
6587 * configure.ac: Define "lint" if --enable-gcc-warnings.
6589 2002-11-05 Akim Demaille <akim@epita.fr>
6591 * src/scan-gram.l: When it starts with `%', complain about the

6610 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
6612 * src/scan-gram.l: Use [\'] instead of ['] to pacify
6615 Use quote, not quote_n since LOCATION_PRINT no longer uses the
6618 2002-11-03 Paul Eggert <eggert@twinsun.com>
6620 * src/reader.c (get_merge_function, grammar_current_rule_check):
6621 Use consistent diagnostics for reporting type name clashes.

6636 Use b4_identification.
6637 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
6638 b4_user_formals and b4_user_args.
6639 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
6640 (yyreportAmbiguity): When using a pure parser, also need
6641 the location, and the parse-params.
6643 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
6644 When using a pure parser, also need the parse-params.
6646 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
6647 (%pure-parser + %parse-param) LALR and GLR parsers.
6648 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
6649 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

6667 2002-11-03 Paul Eggert <eggert@twinsun.com>
6669 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
6670 to count columns correctly, and to check for invalid inputs.
6672 Use mbsnwidth to count columns correctly. Account for tabs, too.
6674 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
6675 (extend_location): New function.
6678 Handle CRLF in C code rather than in Lex code.

6682 Scan UCNs, even though we don't fully handle them yet.
6683 (convert_ucn_to_byte): New function.
6685 Handle backslash-newline correctly in C code.
6686 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.

6691 YY_STEP after space, newline, vertical-tab.
6692 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
6694 (letter, id): Don't assume ASCII; e.g., spell out a-z.
6696 ({int}, handle_action_dollar, handle_action_at): Check for integer
6699 (YY_STEP): Omit trailing semicolon, so that it's more like C.
6701 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
6702 as well as \000. Check for UCHAR_MAX, not 255.
6703 Allow \x with an arbitrary positive number of digits, as in C.
6704 Check for overflow here.
6705 Allow \? and UCNs, for compatibility with C.
6707 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
6708 with quote slot used by complain_at.
6710 * tests/input.at: Add tests for backslash-newline, m4 quotes
6711 in symbols, long literals, and funny escapes in strings.
6713 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
6714 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

6727 2002-11-02 Paul Eggert <eggert@twinsun.com>
6729 * src/reader.c: Don't include quote.h; not needed.

6736 * src/output.c (prepare_symbols): When printing token names,
6737 escape "[" as "@<:@" and likewise for "]".
6739 * src/system.h (errno): Remove declaration, as we are now
6740 assuming C89 or better, and C89 guarantees errno.
6742 2002-10-30 Paul Eggert <eggert@twinsun.com>
6744 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
6745 Check for close failures.
6746 * src/files.h (xfclose): Return void, not int, since it always
6748 * src/files.c (xfclose): Likewise. Report I/O error if ferror
6750 * src/output.c (output_skeleton): Use xfclose rather than fclose
6751 and ferror. xfclose now checks ferror.
6753 * data/glr.c (YYLEFTMOST_STATE): Remove.
6754 (yyreportTree): Use a stack-based leftmost state. This avoids
6755 our continuing battles with bogus warnings about initializers.
6757 2002-10-30 Akim Demaille <akim@epita.fr>
6759 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

6772 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6773 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6774 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6775 Don't assume strdup exists; POSIX says its an XSI extension.
6776 Check for buffer overflow on input.
6778 2002-10-24 Akim Demaille <akim@epita.fr>
6780 * src/output.c (output_skeleton): Don't disable M4sugar comments
6781 too soon: it results in comments being expanded.
6782 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6785 2002-10-24 Akim Demaille <akim@epita.fr>
6787 * data/yacc.c (m4_int_type): New.
6788 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6789 char' as only yacc.c wants K&R portability.

6791 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
6792 Reported by Quoc Peyrot.
6794 2002-10-23 Paul Eggert <eggert@twinsun.com>
6796 * src/main.c (main): With --trace=time, report times even if a
6797 non-fatal error occurs. Formerly, the times were reported in some
6798 such cases but not in others.
6799 * src/reader.c (reader): Just return if a complaint has been issued,
6800 instead of exiting, so that 'main' can report times.
6802 2002-10-22 Akim Demaille <akim@epita.fr>
6804 * src/system.h: Include sys/types.
6805 Reported by Bert Deknuydt.
6807 2002-10-23 Paul Eggert <eggert@twinsun.com>
6809 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.

6814 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6815 decl; not needed any more.
6816 * src/main.c (main): Use return to exit, undoing yesterday's change.
6817 The last OS that we could find where this wouldn't work is
6818 SunOS 3.5, and that's too old to worry about now.
6820 * data/glr.c (struct yyltype): Define members even when not
6821 doing locations. This is more consistent with yacc.c, and it
6822 works around the following bug reports:
6823 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6824 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6826 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6827 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6828 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6830 2002-10-22 Akim Demaille <akim@epita.fr>
6834 2002-10-21 Paul Eggert <eggert@twinsun.com>
6836 Be consistent about 'bool'; the old code used an enum in one
6837 module and an int in another, and this violates the C standard.
6838 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6839 * configure.ac (AC_HEADER_STDBOOL): Add.
6840 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

6842 * src/symtab.c (hash_compare_symbol_t): Likewise.
6843 * src/system.h (bool, false, true): Use a definition consistent
6844 with ../lib/hash.c. All uses changed.
6846 * src/complain.c (warning_issued): Renamed from warn_message_count,
6847 so that we needn't worry about integer overflow (!).
6848 Now of type bool. All uses changed.
6849 (complaint_issued): Renamed from complain_message_count; likewise.
6851 * src/main.c (main): Use exit to exit with failure.
6853 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6854 rather than 1 and 0.
6855 * src/main.c (main): Likewise.
6856 * src/getargs.c (getargs): Likewise.
6857 * src/reader.c (reader): Likewise.
6859 * src/getarg.c (getargs): Remove duplicate code for
6860 "Try `bison --help'".
6862 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6863 What was that "2" for?
6865 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6866 * src/getargs.c (usage): Likewise.
6868 * src/getargs.c (getargs): When there are too few operands, report
6869 the last one. When there are too many, report the first extra
6870 one. This is how diffutils does it.
6872 2002-10-20 Paul Eggert <eggert@twinsun.com>
6874 Remove K&R vestiges.
6875 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
6876 * src/complain.c (VA_START): Remove. Assume prototypes.
6877 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
6878 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
6879 fatal): Assume prototypes.
6880 * src/complain.h: Assume prototypes.
6881 * src/system.h (PARAMS): Remove.
6882 Include <limits.h> unconditionally, since it's guaranteeed even
6883 for a freestanding C89 compiler.
6884 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
6885 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
6887 2002-10-20 Akim Demaille <akim@epita.fr>
6889 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

6904 (b4_c_ansi_function_decl): New.
6905 Change the interpretation of the arguments: before `int, foo', now
6907 * data/yacc.c (yyparse): Prototype and define thanks to these.
6908 Adjust b4_c_function_def uses.
6909 * data/glr.c (yyparse): Likewise, but ANSI only.
6911 2002-10-20 Akim Demaille <akim@epita.fr>
6913 * src/output.c (prepare): Move the definition of `tokens_number',
6914 `nterms_number', `undef_token_number', `user_token_number_max'

6918 (prepare_symbols): this.
6919 (prepare): Move the definition of `rules_number' to...
6920 (prepare_rules): here.
6921 (prepare): Move the definition of `last', `final_state_number',
6922 `states_number' to...
6923 (prepare_states): here.

6937 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
6938 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
6940 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',

6943 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
6946 2002-10-19 Paul Eggert <eggert@twinsun.com>
6948 Do not create a temporary file, as that involves security and
6949 cleanup headaches. Instead, use a pair of pipes.
6950 Derived from a suggestion by Florian Krohm.
6951 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
6952 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

6966 (scan_skel): New function, to be used in place of m4_invoke.
6967 Read from stream rather than file.
6969 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
6970 float, as this generates a warning on Solaris 8 + GCC 3.2 with
6971 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
6972 this generates a more-accurate value anyway.
6974 * lib/timevar.c (timervar_accumulate): Rename locals to
6975 avoid confusion with similarly-named more-global.
6976 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
6978 * src/output.c (prepare): Use xstrdup to convert char const *
6979 to char *, to avoid GCC warning.
6981 2002-10-19 Akim Demaille <akim@epita.fr>
6983 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
6984 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.

6986 * data/yacc.c (YYLEX): Pass a yylex return type to
6989 2002-10-19 Akim Demaille <akim@epita.fr>
6991 Prototype support of %lex-param and %parse-param.
6993 * src/parse-gram.y: Add the definition of the %lex-param and
6994 %parse-param tokens, plus their rules.
6995 Drop the `_' version of %glr-parser.
6997 * src/scan-gram.l (INITIAL): Scan them.
6998 * src/muscle_tab.c: Comment changes.

7015 * src/getargs.c (usage): Take status as argument and exit
7017 Report the traditional `Try ... --help' message when status != 0.
7018 (usage, version): Don't take a FILE * as arg, it is pointless.
7019 (getargs): When there is an incorrect number of arguments, make it
7020 an error, and report it GNUlically thanks to `usage ()'.
7022 2002-10-18 Paul Eggert <eggert@twinsun.com>
7024 * data/glr.c (yyreportParseError): Don't assume that sprintf
7025 yields the length of the printed string, as this is not true

7059 Stop using the "enum_" trick for K&R-style function definitions;
7060 it confused me, and I was the author! Instead, assume that people
7061 who want to use K&R C compilers (when using these modules in GCC,
7062 perhaps?) will run ansi2knr.

7160 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,

7170 true due to limited range of data type" warning from GCC.
7172 * data/c.m4 (b4_token_defines): Protect against double-inclusion
7173 by wrapping enum yytokentype's definition inside #ifndef
7174 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.

7194 Let nondeterministic skeletons be usable with deterministic
7197 With the patch, GAWK compiled by GCC without -O2 passes its test
7198 suite using a GLR parser driven by LALR tables. It fails with -O2
7199 because `struct stat' gives two different answers on my machine:
7200 88 (definition of an auto var) and later 96 (memset on this var).
7201 Hence the stack is badly corrumpted. The headers inclusion is to
7202 blame: if I move the awk.h inclusion before GLR's system header
7203 inclusion, the two struct stat have the same size.
7205 * src/tables.c (pack_table): Always create conflict_table.
7206 (token_actions): Always create conflict_list.
7207 * data/glr.c (YYFLAG): Remove, unused.

7227 GLR parsers sometimes raise parse errors instead of performing the

7231 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
7232 check the length of the traces when %glr.
7233 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
7235 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
7237 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
7238 (yyltype): Remove the yy prefix from the member names.
7239 (yytable): Complete its comment.
7240 (yygetLRActions): Map error action number from YYTABLE from
7242 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
7243 (which was a bug: it should have been YYTABEL_NINF, and yet it was
7244 not satisfying as we could compare an YYACTION computed from
7245 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
7246 only value for error actions.
7247 (yyreportParseError): In verbose parse error messages, don't issue
7248 `error' in the list of expected tokens.
7249 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
7250 next action to perform to match glr.c's decoding.

7257 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
7258 because the Bison parser reads the second action before reducing
7260 * src/scan-gram.l (rule_length): New static var.
7261 Use it to keep track of the rule length in the scanner, since
7262 we can't expect the parser to be in lock-step sync with the scanner.
7263 (handle_action_dollar, handle_action_at): Use this var.

7276 (get_time) [IN_GCC]: Keep the GCC version for reference.
7278 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
7279 GCC version as of today, then merge Bison's changes.
7280 Change "GCC" to "Bison" in copyright notice. timevar.def's
7281 author is Akim, so change that too.

7781 this is a GCC extension and is not portable to other compilers.

7922 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.

8020 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
8021 for the time being: %locations ought to provide it to yyerror.
8023 2002-07-25 Akim Demaille <akim@epita.fr>
8025 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

10457 forces `.' in the PATH.
10459 2002-01-25 Akim Demaille <akim@epita.fr>
10461 * tests/regression.at (%nonassoc and eof): New.
10462 Suggested by Robert Anisko.
10464 2002-01-24 Akim Demaille <akim@epita.fr>
10466 Bison dumps core when trying to complain about broken input files.
10467 Reported by Cris van Pelt.
10469 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
10470 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
10472 (Invalid inputs): Strengthen: exercise parse_percent_token.
10474 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
10476 * src/Makefile.am: Add bison.c++.
10477 * src/bison.c++: New skeleton.
10479 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
10483 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
10485 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
10487 2002-01-20 Marc Autret <marc@gnu.org>
10489 * src/files.c (compute_output_file_names): Fix
10491 2002-01-20 Marc Autret <marc@gnu.org>
10493 * tests/output.at: New test.
10494 * src/files.c (compute_base_names): Don't map extensions when
10495 the YACC flag is set, use defaults.
10496 Reported by Evgeny Stambulchik.
10498 2002-01-20 Marc Autret <marc@gnu.org>
10500 * src/system.h: Need to define __attribute__ away for non-GCC
10501 compilers as well (i.e., the vendor C compiler).
10502 Suggested by Albert Chin-A-Young.
10504 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
10506 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
10507 canonical definition.
10508 * src/system.h: Use the canonical definition for PARAMS (avoids
10509 a conflict with the macro from lib/hash.h).
10511 2002-01-11 Akim Demaille <akim@epita.fr>
10513 * configure.in: Use AC_FUNC_STRNLEN.
10514 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
10516 2002-01-09 Akim Demaille <akim@epita.fr>
10518 * src/files.c, src/files.h (output_infix): New.
10519 (tab_extension): Remove.
10520 (compute_base_names): Compute the former, drop the latter.
10521 * src/output.c (prepare): Insert the muscles `output-infix', and
10523 * src/parse-skel.y (string, string.1): New.
10524 (section.header): Use it.
10525 (section.yacc): Remove.
10526 (prefix): Remove too.
10527 * src/scan-skel.l: Adjust.
10528 * src/bison.simple, src/bison.hairy: Adjust.
10530 2002-01-09 Akim Demaille <akim@epita.fr>
10532 * configure.in (WERROR_CFLAGS): Compute it.
10533 * src/Makefile.am (CFLAGS): Pass it.
10534 * tests/atlocal.in (CFLAGS): Idem.
10535 * src/files.c: Fix a few warnings.
10536 (get_extension_index): Remove, unused.
10538 2002-01-08 Akim Demaille <akim@epita.fr>
10540 * src/getargs.c (AS_FILE_NAME): New.
10541 (getargs): Use it to convert DOSish file names.
10542 * src/files.c (base_name): Rename as full_base_name to avoid
10543 clashes with `base_name ()'.
10544 (filename_split): New.
10545 (compute_base_names): N-th rewrite, using filename_split.
10547 2002-01-08 Akim Demaille <akim@epita.fr>
10549 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10550 New, stolen from the Fileutils 4.1.
10551 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10552 * configure.in: Check for the presence of memrchr, and of its
10555 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10557 * lib/hash.h (__P): Added definition for this macro.
10558 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10559 BUILT_SOURCES, to ensure they are generated first.
10560 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10561 %error-verbose to allow bootstrapping with bison 1.30x.
10563 2002-01-06 Akim Demaille <akim@epita.fr>
10565 * src/reader.c (parse_braces): Don't fetch the next char, the
10566 convention is to fetch on entry.
10567 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10568 'switch' without a following semicolon.
10569 * tests/regression.at (braces parsing): New.
10571 2002-01-06 Akim Demaille <akim@epita.fr>
10573 Bison is dead wrong in its RR conflict reports.
10575 * tests/torture.at (GNU Cim Grammar): New.
10576 * src/conflicts.c (count_rr_conflicts): Fix.
10578 2002-01-06 Akim Demaille <akim@epita.fr>
10580 Creating package.m4 from configure.ac causes too many problems.
10582 * tests/Makefile.am (package.m4): Create it by hand,
10583 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10585 2002-01-06 Akim Demaille <akim@epita.fr>
10587 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10590 2002-01-04 Paul Eggert <eggert@twinsun.com>
10592 * doc/bison.texinfo (Debugging):
10593 Remove YYSTDERR; it's no longer defined or used.
10594 Also, s/cstdio.h/cstdio/.
10596 2002-01-03 Akim Demaille <akim@epita.fr>
10598 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10600 2002-01-03 Akim Demaille <akim@epita.fr>
10602 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10603 tracing code to --trace, wait for a better --trace option, with
10606 2002-01-03 Akim Demaille <akim@epita.fr>
10608 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10609 The ISO C++ standard is extremely clear about it: stderr is
10610 considered a macro, not a regular symbol (see table 94 `Header
10611 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10612 Therefore std:: does not apply to it. It still does with fprintf.
10613 Also, s/cstdio.h/cstdio/.
10615 2002-01-03 Akim Demaille <akim@epita.fr>
10617 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10618 for non system headers.
10620 2002-01-02 Akim Demaille <akim@epita.fr>
10622 Equip the skeleton chain with location tracking, runtime trace,
10623 pure parser and scanner.
10625 * src/parse-skel.y: Request a pure parser, locations, and prefix
10627 (%union): Having several members with the same type does not help
10628 type mismatches, simplify.
10629 (YYPRINT, yyprint): New.
10630 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10631 (skel_error): this.
10633 * src/scan-skel.l: Adjust to these changes.
10634 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10635 (LOCATION_PRINT, skel_control_t): New.
10637 2001-12-30 Akim Demaille <akim@epita.fr>
10639 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10640 replace `gb' with BLANKS.
10641 * src/scan-skel.l: Adjust.
10643 2001-12-30 Akim Demaille <akim@epita.fr>
10645 * src/system.h: We don't need nor want bcopy.
10646 Throw away MS-DOS crap: we don't need getpid.
10647 * configure.in: We don't need strndup. It was even causing
10648 problems: because Flex includes the headers *before* us,
10649 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10651 * lib/xstrndup.c: New.
10652 * src/scan-skel.l: Use it.
10653 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10654 * src/parse-skel.y: Use %directives instead of #defines.
10656 2001-12-30 Akim Demaille <akim@epita.fr>
10658 * src/skeleton.h: New.
10659 * src/output.c (output_parser, output_master_parser): Remove, dead
10661 * src/output.h (get_lines_number, actions_output, guards_output)
10662 (token_definitions_output): Prototype them.
10663 * src/parse-skel.y: Add the license notice.
10664 Include output.h and skeleton.h.
10665 (process_skeleton): Returns void, and takes a single parameter.
10666 * src/scan-skel.l: Add the license notice.
10667 Include skeleton.h.
10668 Don't use %option yylineno: it seems that then Flex imagines
10669 REJECT has been used, and therefore it won't reallocate its
10670 buffers (which makes no other sense to me than a bug). It results
10671 in warnings for `unused: yy_flex_realloc'.
10673 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10675 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10676 (MUSCLE_INSERT_PREFIX): ...to there.
10677 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10678 (MUSCLE_INSERT_PREFIX): Move from here...
10680 * src/bison.hairy: Add a section directive. Put braces around muscle
10681 names. This parser skeleton is still broken, but Bison should not
10682 choke on a bad muscle 'syntax'.
10683 * src/bison.simple: Add a section directive. Put braces around muscle
10686 * src/files.h (strsuffix, stringappend): Add declarations.
10687 (tab_extension): Add declaration.
10688 (short_base_name): Add declaration.
10690 * src/files.c (strsuffix, stringappend): No longer static. These
10691 functions are used in the skeleton parser.
10692 (tab_extension): New.
10693 (compute_base_names): Use the computations done in this function
10694 to guess if the generated parsers should have '.tab' in their
10696 (short_base_name): No longer static.
10698 * src/output.c (output_skeleton): New.
10699 (output): Disable call to output_master_parser, and give a try to
10700 a new skeleton handling system.
10701 (guards_output, actions_output): No longer static.
10702 (token_definitions_output, get_lines_number): No longer static.
10704 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
10706 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
10709 * src/parse-skel.y: New file.
10710 * src/scan-skel.l: New file.
10712 2001-12-29 Akim Demaille <akim@epita.fr>
10714 %name-prefix is broken.
10716 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10717 Adjust all dependencies.
10718 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10721 Renaming yylval but not yylloc is not consistent. Now we do.
10723 * src/bison.simple: Prefix yylloc if used.
10724 * doc/bison.texinfo (Decl Summary): Document that.
10726 2001-12-29 Akim Demaille <akim@epita.fr>
10728 * doc/bison.texinfo: Promote `%long-directive' over
10730 Remove all references to fixed-output-files, yacc is enough.
10732 2001-12-29 Akim Demaille <akim@epita.fr>
10734 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10735 user prologue. These are defaults.
10736 * tests/actions.at (Mid-rule actions): Make sure the user can
10737 define YYDEBUG and YYERROR_VERBOSE.
10739 2001-12-29 Akim Demaille <akim@epita.fr>
10741 * src/output.c (header_output): Don't forget to export YYLTYPE and
10743 * tests/headers.at (export YYLTYPE): New, make sure it does.
10744 * tests/regression.at (%union and --defines, Invalid CPP headers):
10746 * tests/headers.at: here.
10748 2001-12-29 Akim Demaille <akim@epita.fr>
10750 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
10752 2001-12-29 Akim Demaille <akim@epita.fr>
10754 * tests/actions.at (Mid-rule actions): Output on a single line
10755 instead of several.
10757 2001-12-29 Akim Demaille <akim@epita.fr>
10759 * doc/bison.texinfo: Formatting changes.
10761 2001-12-29 Akim Demaille <akim@epita.fr>
10763 Don't store the token defs in a muscle, just be ready to output it
10764 on command. Now possible via `symbols'. Fixes a memory leak.
10766 * src/output.c (token_definitions_output): New.
10767 (output_parser, header_output): Use it.
10768 * src/reader.c (symbols_save): Remove.
10770 2001-12-29 Akim Demaille <akim@epita.fr>
10772 * src/bison.simple: Do not provide a default for YYSTYPE and
10773 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10776 2001-12-29 Akim Demaille <akim@epita.fr>
10778 Mid-rule actions are simply... ignored!
10780 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10781 the empty-rule associated to the dummy symbol, not to the host
10783 * tests/actions.at (Mid-rule actions): New.
10785 2001-12-29 Akim Demaille <akim@epita.fr>
10789 * src/reader.c (reader): Free grammar.
10791 2001-12-29 Akim Demaille <akim@epita.fr>
10795 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10796 since it allocates it for each state, although only one is needed.
10797 (allocate_storage): Do it here.
10799 2001-12-29 Akim Demaille <akim@epita.fr>
10801 * src/options.h, src/options.c (create_long_option_table): Rename
10803 (long_option_table_new): this, with a clearer prototype.
10804 (percent_table): Remove, unused,
10805 * src/getargs.c (getargs): Adjust.
10807 2001-12-29 Akim Demaille <akim@epita.fr>
10809 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
10810 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
10813 2001-12-29 Akim Demaille <akim@epita.fr>
10815 * src/lalr.c (build_relations): Rename `states' as `states1'.
10816 Sorry, I don't understand exactly what it is, no better name...
10818 2001-12-29 Akim Demaille <akim@epita.fr>
10820 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10821 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
10822 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
10825 2001-12-29 Akim Demaille <akim@epita.fr>
10827 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
10830 2001-12-29 Akim Demaille <akim@epita.fr>
10832 * src/reader.c, src/reader.h (user_toknums): Remove.
10833 Adjust all users to use symbols[i]->user_token_number.
10835 2001-12-29 Akim Demaille <akim@epita.fr>
10837 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
10838 Adjust all users to use symbols[i]->prec or ->assoc.
10840 2001-12-29 Akim Demaille <akim@epita.fr>
10842 * src/reader.c, src/reader.h (tags): Remove.
10843 Adjust all users to use symbols[i]->tag.
10845 2001-12-29 Akim Demaille <akim@epita.fr>
10847 * src/gram.h, src/gram.c (symbols): New, similar to state_table
10849 * src/reader.c (packsymbols): Fill this table.
10851 * src/conflicts.c (resolve_sr_conflict): Adjust.
10852 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10854 Use symbols[i]->tag instead of tags[i].
10856 2001-12-29 Akim Demaille <akim@epita.fr>
10858 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10859 In addition, put a comment in there, to replace...
10860 * tests/regression.at (%union and C comments): Remove.
10862 2001-12-29 Akim Demaille <akim@epita.fr>
10864 * tests/regression.at (Web2c Actions): Blindly move the actual
10865 output as expected output. The contents *seem* right to me, but I
10866 can't pretend reading perfectly parser tables... Nonetheless, all
10867 the other tests pass correctly, the table look OK, even though the
10868 presence of `$axiom' is to be noted: AFAICS it is useless (but
10871 2001-12-29 Akim Demaille <akim@epita.fr>
10873 * src/reader.c (readgram): Don't add the rule 0 if there were no
10874 rules read. In other words, add it _after_ having performed
10875 grammar sanity checks.
10876 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
10878 2001-12-29 Akim Demaille <akim@epita.fr>
10880 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
10881 visible, and some states have now a different number.
10883 2001-12-29 Akim Demaille <akim@epita.fr>
10885 * src/reader.c (readgram): Bind the initial rule's lineno to that
10887 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
10888 (Solved SR Conflicts): Adjust rule 0's line number.
10890 2001-12-29 Akim Demaille <akim@epita.fr>
10892 Fix the `GAWK Grammar' failure.
10894 * src/LR0.c (final_state): Initialize to -1 so that we do compute
10895 the reductions of the first state which was mistakenly confused
10896 with the final state because precisely final_state was initialized
10898 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
10899 now noticed by Bison.
10900 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
10901 have a reduction on $default.
10903 2001-12-29 Akim Demaille <akim@epita.fr>
10905 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
10907 * src/closure.c (print_closure): Likewise.
10908 * src/derives.c (print_derives): Likewise.
10909 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
10912 2001-12-29 Akim Demaille <akim@epita.fr>
10914 * src/lalr.c (lookaheads_print): New.
10915 (lalr): Call it when --trace-flag.
10916 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
10919 2001-12-29 Akim Demaille <akim@epita.fr>
10921 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
10922 when walking through ritem, even via rule->rhs.
10923 * src/reduce.c (dump_grammar, useful_production, reduce_output)
10924 (useful_production, useless_nonterminals): Likewise.
10925 (reduce_grammar_tables): Likewise, plus update nritems.
10926 * src/nullable.c (set_nullable): Likewise.
10927 * src/lalr.c (build_relations): Likewise.
10928 * tests/sets.at (Nullable): Adjust.
10929 Fortunately, now, the $axiom is no longer nullable.
10931 2001-12-29 Akim Demaille <akim@epita.fr>
10933 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
10935 * src/gram.c (ritem_longest_rhs): Likewise.
10936 * src/reduce.c (nonterminals_reduce): Likewise.
10937 * src/print_graph.c (print_graph): Likewise.
10938 * src/output.c (output_rule_data): Likewise.
10939 * src/nullable.c (set_nullable): Likewise.
10941 2001-12-29 Akim Demaille <akim@epita.fr>
10943 * src/output.c: Comment changes.
10945 2001-12-27 Paul Eggert <eggert@twinsun.com>
10947 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
10948 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
10949 Sparc, as they were causing more porting problems than the
10950 (minor) performance improvement was worth.
10952 Also, catch up with 1.31's YYSTD.
10954 2001-12-27 Akim Demaille <akim@epita.fr>
10956 * src/output.c (output_gram): Rely on nritems, not the
10957 0-sentinel. See below.
10958 Use -1 as separator, not 0.
10959 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
10960 Rely on -1 as separator in yyrhs, instead of 0.
10961 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
10962 twice `Now at end of input', therefore there are two lines less to
10965 2001-12-27 Akim Demaille <akim@epita.fr>
10967 * tests/regression.at (Unresolved SR Conflicts):
10968 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
10971 2001-12-27 Akim Demaille <akim@epita.fr>
10973 * src/LR0.c (new_state): Recognize the final state by the fact it
10974 is reached by eoftoken.
10975 (insert_start_shifting_state, insert_eof_shifting_state)
10976 (insert_accepting_state, augment_automaton): Remove, since now
10977 these states are automatically computed from the initial state.
10978 (generate_states): Adjust.
10979 * src/print.c: When reporting a rule number to the user, substract
10980 1, so that the axiom rule is rule 0, and the first user rule is 1.
10981 * src/reduce.c: Likewise.
10982 * src/print_graph.c (print_core): For the time being, just as for
10983 the report, depend upon --trace-flags to dump the full set of
10985 * src/reader.c (readgram): Once the grammar read, insert the rule
10986 0: `$axiom: START-SYMBOL $'.
10987 * tests/set.at: Adjust: rule 0 is now displayed, and since the
10988 number of the states has changed (the final state is no longer
10989 necessarily the last), catch up.
10991 2001-12-27 Akim Demaille <akim@epita.fr>
10993 Try to make the use of the eoftoken valid. Given that its value
10994 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
10995 is used instead of > 0 where appropriate, (ii), depend upon nritems
10996 instead of the 0-sentinel.
10998 * src/gram.h, src/gram.c (nritems): New.
10999 Expected to be duplication of nitems, but for the time being...
11000 * src/reader.c (packgram): Assert nritems and nitems are equal.
11001 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
11002 * src/closure.c (print_closure, print_fderives): Likewise.
11003 * src/gram.c (ritem_print): Likewise.
11004 * src/print.c (print_core, print_grammar): Likewise.
11005 * src/print_graph.c: Likewise.
11007 2001-12-27 Akim Demaille <akim@epita.fr>
11009 * src/main.c (main): If there are complains after grammar
11010 reductions, then output the report anyway if requested, then die.
11011 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
11012 * src/reader.c (eoftoken): New.
11013 (parse_token_decl): If the token being defined has value `0', it
11015 (packsymbols): No longer hack `tags' to insert `$' by hand.
11016 Be sure to preserve the value of the eoftoken.
11017 (reader): Make sure eoftoken is defined.
11018 Initialize nsyms to 0: now eoftoken is created just like the others.
11019 * src/print.c (print_grammar): Don't special case the eof token.
11020 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
11021 lie anyway, albeit pleasant.
11022 * tests/calc.at: Exercise error messages with eoftoken.
11023 Change the grammar so that empty input is invalid.
11024 Adjust expectations.
11025 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
11027 2001-12-27 Akim Demaille <akim@epita.fr>
11029 * configure.in: Check the protos of strchr ans strspn.
11030 Replace strchr if needed.
11031 * src/system.h: Provide the protos of strchr, strspn and memchr if
11033 * lib/strchr.c: New.
11034 * src/reader.c (symbols_save): Use strchr.
11036 2001-12-27 Akim Demaille <akim@epita.fr>
11038 * src/print.c, src/print_graph.c (escape): New.
11039 Use it to quote the TAGS outputs.
11040 * src/print_graph.c (print_state): Now errors are in red, and
11041 reductions in green.
11042 Prefer high to wide: output the state number on a line of its own.
11044 2001-12-27 Akim Demaille <akim@epita.fr>
11046 * src/state.h, src/state.c (reductions_new): New.
11047 * src/LR0.c (set_state_table): Let all the states have a
11048 `reductions', even if reduced to 0.
11049 (save_reductions): Adjust.
11050 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
11051 * src/print.c (print_reductions, print_actions): Adjust.
11052 * src/output.c (action_row): Adjust.

11057 * src/LR0.c (set_state_table): Let all the states have an errs,
11058 even if reduced to 0.
11059 * src/print.c (print_errs, print_reductions): Adjust.
11060 * src/output.c (output_actions, action_row): Adjust.
11061 * src/conflicts.c (resolve_sr_conflict): Adjust.
11063 2001-12-27 Akim Demaille <akim@epita.fr>
11065 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
11067 2001-12-27 Akim Demaille <akim@epita.fr>
11069 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
11070 * src/print.c: here.
11071 (lookaheadset, shiftset): New, used as additional storage by
11073 (print_results): Adjust.
11074 (print_shifts, print_gotos, print_errs): New, extracted from...
11075 (print_actions): here.
11076 * src/print_graph.c (print_actions): Remove dead code.
11078 2001-12-27 Akim Demaille <akim@epita.fr>
11080 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
11083 2001-12-27 Akim Demaille <akim@epita.fr>
11085 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
11086 (build_relations): Adjust.
11088 2001-12-27 Akim Demaille <akim@epita.fr>
11090 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
11093 2001-12-27 Akim Demaille <akim@epita.fr>
11095 * src/reader.c (packgram): Catch nitems overflows.
11097 2001-12-27 Akim Demaille <akim@epita.fr>
11099 * src/files.c, src/files.h (guard_obstack): Remove.
11100 * src/output.c (output): Adjust.
11101 * src/reader.c (parse_braces): New, factoring...
11102 (copy_action, copy_guard): these two which are renamed as...
11103 (parse_action, parse_guard): these.
11104 As a voluntary consequence, using braces around guards is now
11107 2001-12-27 Akim Demaille <akim@epita.fr>
11109 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
11110 * src/reader.c (symbol_list): `guard' and `guard_line' are new
11112 (symbol_list_new): Adjust.
11113 (copy_action): action_line is the first line, not the last.
11114 (copy_guard): Just as for actions, store the `action' only, not
11115 the switch/case/break flesh.
11116 Don't parse the user action that might follow the guard, let...
11117 (readgram): do it, i.e., now, there can be an action after a
11119 In other words the guard is just explicitly optional.
11120 (packgram): Adjust.
11121 * src/output.c (guards_output): New.
11122 (output_parser): Call it when needed.
11123 (output): Also free the guard and attrs obstacks.
11124 * src/files.c, src/files.h (obstack_save): Remove.
11125 (output_files): Remove.
11126 As a result, if one needs the former `.act' file, using an
11127 appropriate skeleton which requires actions and guards is now
11129 * src/main.c (main): Adjust.
11130 * tests/semantic.at: New.
11131 * tests/regression.at: Use `input.y' as input file name.
11132 Avoid 8+3 problems by requiring input.c when the test needs the
11135 2001-12-27 Akim Demaille <akim@epita.fr>
11137 * src/reader.c (symbol_list_new): Be sure to initialize all the
11140 2001-12-27 Akim Demaille <akim@epita.fr>
11142 All the hacks using a final pseudo state are now useless.
11144 * src/LR0.c (set_state_table): state_table holds exactly nstates.
11145 * src/lalr.c (nLA): New.
11146 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
11147 instead of lookaheadsp from the pseudo state (nstate + 1).
11149 2001-12-27 Akim Demaille <akim@epita.fr>
11151 * src/output.c (action_row, token_actions): Use a state_t instead
11152 of a integer, and nlookaheads instead of the following state's

11157 * src/conflicts.c (log_resolution, flush_shift)
11158 (resolve_sr_conflict, set_conflicts, solve_conflicts)
11159 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
11160 (conflicts_print, print_reductions): Use a state_t instead of an
11161 integer when referring to a state.
11162 As much as possible, depend upon nlookaheads, instead of the
11163 `lookaheadsp' member of the following state (since lookaheads of
11164 successive states are successive, the difference between state n + 1
11165 and n served as the number of lookaheads for state n).
11166 * src/lalr.c (add_lookback_edge): Likewise.
11167 * src/print.c (print_core, print_actions, print_state)
11168 (print_results): Likewise.
11169 * src/print_graph.c (print_core, print_actions, print_state)
11170 (print_graph): Likewise.

11178 Add plenty of `static'.
11180 2001-12-27 Akim Demaille <akim@epita.fr>
11182 * src/output.c (prepare): Drop the muscle `ntbase' which
11183 duplicates ntokens.
11184 * src/bison.simple: Formatting/comment changes.
11185 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
11186 is an undocumented synonym.
11188 2001-12-22 Akim Demaille <akim@epita.fr>
11190 * src/output.c (output_table_data): Change the prototype to use
11191 `int' for array ranges: some invocations do pass an int, not a
11193 Reported by Wayne Green.
11195 2001-12-22 Akim Demaille <akim@epita.fr>
11197 Some actions of web2c.y are improperly triggered.
11198 Reported by Mike Castle.
11200 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
11201 * tests/regression.at (Web2c): Rename as...
11202 (Web2c Report): this.
11203 (Web2c Actions): New.
11205 2001-12-22 Akim Demaille <akim@epita.fr>
11207 Reductions in web2c.y are improperly reported.
11208 Reported by Mike Castle.
11210 * src/conflicts.c (print_reductions): Fix.
11211 * tests/regression.at (Web2c): New.
11213 2001-12-18 Akim Demaille <akim@epita.fr>
11215 Some host fail on `assert (!"foo")', which expands to
11216 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
11217 Reported by Nelson Beebee.
11219 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
11220 `#define it_succeeded 0' and `assert (it_succeeded)'.
11222 2001-12-17 Marc Autret <autret_m@epita.fr>
11224 * src/bison.simple: Don't hard code the skeleton line and filename.
11225 * src/output.c (output_parser): Rename 'line' as 'output_line'.
11226 New line counter 'skeleton_line' (skeleton-line muscle).
11228 2001-12-17 Paul Eggert <eggert@twinsun.com>
11230 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
11231 YYDEBUG must be defined to a nonzero value.
11233 * src/bison.simple (yytname): Do not assume that the user defines
11234 YYDEBUG to a properly parenthesized expression.
11236 2001-12-17 Akim Demaille <akim@epita.fr>
11238 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
11239 nlookaheads is a new member.
11241 * src/lalr.h (nlookaheads): Remove this orphan declaration.
11242 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
11245 2001-12-17 Akim Demaille <akim@epita.fr>
11247 * src/files.h, src/files.c (open_files, close_files): Remove.
11248 * src/main.c (main): Don't open/close files, nor invoke lex_free,
11250 * src/reader.c (reader): Do it.
11252 2001-12-17 Akim Demaille <akim@epita.fr>
11254 * src/conflicts.c (print_reductions): Formatting changes.
11256 2001-12-17 Akim Demaille <akim@epita.fr>
11258 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
11259 (flush_reduce): New.
11260 (resolve_sr_conflict): Adjust.
11262 2001-12-17 Akim Demaille <akim@epita.fr>
11264 * src/output.c (output_obstack): Be static and rename as...
11265 (format_obstack): this, to avoid any confusion with files.c's
11267 * src/reader.h (muscle_obstack): Move to...
11268 * src/output.h: here, since it's defined in output.c.
11270 2001-12-17 Akim Demaille <akim@epita.fr>
11272 * src/output.c (action_row, save_column, default_goto)
11273 (sort_actions, matching_state, pack_vector): Better variable
11276 2001-12-17 Akim Demaille <akim@epita.fr>
11278 * src/output.c: Various formatting changes.
11280 2001-12-17 Akim Demaille <akim@epita.fr>
11282 * src/files.c (output_files): Free the output_obstack.
11283 * src/main.c (main): Call print and print_graph conditionally.
11284 * src/print.c (print): Work unconditionally.
11285 * src/print_graph.c (print_graph): Work unconditionally.
11286 * src/conflicts.c (log_resolution): Output only if verbose_flag.
11288 2001-12-16 Marc Autret <autret_m@epita.fr>
11290 * src/output.c (actions_output): Fix. When we use %no-lines,
11291 there is one less line per action.
11293 2001-12-16 Marc Autret <autret_m@epita.fr>
11295 * src/bison.simple: Remove a useless #line directive.
11296 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
11297 * src/output.c (get_lines_number): New.
11298 (output_parser): Adjust, now takes care about the lines of a
11300 Fix line numbering.
11301 (actions_output): Computes the number of lines taken by actions.
11302 (output_master_parser): Insert new skeleton which is the name of
11303 the output parser file name.
11305 2001-12-15 Marc Autret <autret_m@epita.fr>
11307 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
11309 2001-12-15 Marc Autret <autret_m@epita.fr>
11311 * src/output.c (output_gram): Keep track of the hairy one.
11313 2001-12-15 Akim Demaille <akim@epita.fr>
11315 Make `make distcheck' work.
11317 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
11318 system.h which uses libgettext.h.
11320 2001-12-15 Akim Demaille <akim@epita.fr>
11322 * src/nullable.c (set_nullable): Useless rules must be skipped,
11323 otherwise, since we range over their symbols, we might look at a
11324 nonterminal which no longer ``exists'', i.e., it is not counted in
11325 `nvars', hence we overflow our arrays.
11327 2001-12-15 Akim Demaille <akim@epita.fr>
11329 The header can also be produced directly, without any obstack!
11332 * src/files.c, src/files.h (defines_obstack): Remove.
11333 (compute_header_macro): Global.
11334 (defines_obstack_save): Remove.
11335 * src/reader.c (parse_union_decl): No longer output to
11336 defines_obstack: its content can be found in the `stype' muscle
11338 (output_token_translations): Merge into...
11339 (symbols_output): this.
11341 (symbols_save): this.
11343 * src/output.c (header_output): New.
11346 2001-12-15 Akim Demaille <akim@epita.fr>
11348 * src/reader.c (parse_union_decl): Instead of handling two obstack
11349 simultaneously, use one to define the `stype' muscle, and use the
11350 value of the latter to fill defines_obstack.
11351 (copy_comment): Remove.
11352 (copy_comment2): Work for a single obstack.
11354 (copy_comment): this.
11356 2001-12-15 Akim Demaille <akim@epita.fr>
11358 * src/lex.c, src/lex.h (xgetc): No longer static.
11359 * src/reader.c (parse_union_decl): Revamp.
11361 2001-12-15 Akim Demaille <akim@epita.fr>
11363 Still making progress in separating Bison into (i) input, (ii)
11364 process, (iii) output: now we can directly output the parser file
11365 without using table_obstack at all.
11367 * src/files.c, src/files.h (table_obstack): Bye bye.
11368 (parser_file_name): New.
11369 * src/files.c (compute_output_file_names): Compute it.
11370 * src/output.c (actions_output, output_parser)
11371 (output_master_parser): To a file instead of an obstack.
11373 2001-12-15 Akim Demaille <akim@epita.fr>
11375 Attach actions to rules, instead of pre-outputting them to
11378 * src/gram.h (rule_t): action and action_line are new members.
11379 * src/reader.c (symbol_list): Likewise.
11380 (copy_action): Save the actions within the rule.
11381 (packgram): Save them in rule_table.
11382 * src/output.c (actions_output): New.
11383 (output_parser): Use it on `%%actions'.
11384 (output_rule_data): Don't free rule_table.
11386 (prepare): Don't save the `action' muscle.
11387 * src/bison.simple: s/%%action/%%actions/.
11389 2001-12-15 Akim Demaille <akim@epita.fr>
11391 * src/reader.c (copy_action): When --yacc, don't append a `;'
11392 to the user action: let it fail if lacking.
11393 Suggested by Arnold Robbins and Tom Tromey.
11395 2001-12-14 Akim Demaille <akim@epita.fr>
11397 * src/lex.c (literalchar): Simply return the char you decoded, non
11398 longer mess around with obstacks and int pointers.
11399 Adjust all callers.
11401 2001-12-14 Akim Demaille <akim@epita.fr>
11403 * src/lex.c (literalchar): Don't escape the special characters,
11404 just decode them, and keep them as char (before, eol was output as
11405 the 2 char string `\n' etc.).
11406 * src/output.c (output_rule_data): Use quotearg to output the
11409 2001-12-13 Paul Eggert <eggert@twinsun.com>
11411 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11412 Do not infringe on the global user namespace when using C++.
11413 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11414 All uses of `fprintf' and `stderr' changed.
11416 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11418 2001-12-13 Akim Demaille <akim@epita.fr>
11420 The computation of nullable is broken: it doesn't handle empty
11423 * tests/torture.at (GNU AWK Grammar): New.
11424 * tests/sets.at (Nullable): New.
11425 * src/nullable.c (set_nullable): Instead of blindly looping over
11426 `ritems', loop over the rules, and then over their rhs's.
11428 Work around Autotest bugs.
11430 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11431 frame, because Autotest understand lines starting with a `+' as
11432 traces from the shell. Then, they are not processed properly.
11433 Admittedly an Autotest bug, but we don't have time to wait for
11434 Autotest to catch up.
11435 * tests/regression.at (Broken Closure): Adjust to the new table
11438 * tests/sets.at: here.
11440 2001-12-13 Akim Demaille <akim@epita.fr>
11442 * src/closure.c (closure): Use nrules instead of playing tricks
11443 with BITS_PER_WORD.
11445 2001-12-13 Akim Demaille <akim@epita.fr>
11447 * src/print.c (print_actions): Output the handling of `$' as the
11448 traces do: shifting the token EOF. Before EOF was treated as a
11450 * tests/regression.at: Adjust some tests.
11451 * src/print_graph.c (print_core): Complete the set of items via
11452 closure. The next-to-final and final states are still unsatisfying,
11453 but that's to be addressed elsewhere.
11454 No longer output the rule numbers, but do output the state number.
11455 A single loop for the shifts + gotos is enough, but picked a
11456 distinct color for each.
11457 (print_graph): Initialize and finalize closure.
11459 2001-12-13 Akim Demaille <akim@epita.fr>
11461 * src/reader.c (readgram): Remove dead code, an strip useless
11463 (get_type): Remove, unused.
11465 2001-12-12 Akim Demaille <akim@epita.fr>
11467 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11468 on that of lib/error.c.
11470 2001-12-12 Akim Demaille <akim@epita.fr>
11472 Some hosts don't like `/' in includes.
11474 * src/system.h: Include libgettext.h without qualifying the path.
11475 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11478 2001-12-11 Marc Autret <autret_m@epita.fr>
11480 * src/output.c (output_parser): Remove useless muscle.
11482 2001-12-11 Marc Autret <autret_m@epita.fr>
11484 * src/bison.simple: Remove #line just before %%epilogue. It
11485 is now handled in ...
11486 * src/reader.c (read_additionnal_code): Add the output of a
11487 #line for the epilogue.
11489 2001-12-10 Marc Autret <autret_m@epita.fr>
11491 * src/reader.c (copy_definition): Re-use CPP-outed code which
11492 replace precedent remove.
11493 * src/bison.simple: Remove #line before %%prologue because
11494 %%input-line is wrong at this time.
11496 2001-12-10 Marc Autret <autret_m@epita.fr>
11498 * src/reader.c (symbols_output): Clean up.
11499 * src/output.c (output_gram, output): Clean up.
11501 2001-12-10 Akim Demaille <akim@epita.fr>
11503 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11504 * src/LR0.c (set_state_table): here.
11505 * src/lalr.c (lalr): Call it.
11507 2001-12-10 Akim Demaille <akim@epita.fr>
11509 * src/state.h (shifts): Remove the `number' member: shifts are
11510 attached to state, hence no longer need to be labelled with a
11513 2001-12-10 Akim Demaille <akim@epita.fr>
11515 Now that states have a complete set of members, the linked list of
11516 shifts is useless: just fill directly the state's shifts member.
11518 * src/state.h (shifts): Remove the `next' member.
11519 * src/LR0.c (first_state, last_state): Remove.
11520 Adjust the callers.
11521 (augment_automaton): Don't look for the shifts that must be added
11522 a shift on EOF: it is those of the state we looked for! But now,
11523 since shifts are attached, it is no longer needed to looking
11524 merely by its id: its number.
11526 2001-12-10 Akim Demaille <akim@epita.fr>
11528 * src/LR0.c (augment_automaton): Better variable locality.
11529 Remove an impossible branch: if there is a state corresponding to
11530 the start symbol being shifted, then there is shift for the start
11531 symbol from the initial state.
11533 2001-12-10 Akim Demaille <akim@epita.fr>
11535 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11536 only when appropriate: when insert_start_shifting_state' is not
11538 * tests/regression.at (Rule Line Numbers): Adjust.
11540 2001-12-10 Akim Demaille <akim@epita.fr>
11542 * src/LR0.c (augment_automaton): Now that all states have shifts,
11543 merge the two cases addition shifts to the initial state.
11545 2001-12-10 Akim Demaille <akim@epita.fr>
11547 * src/lalr.c (set_state_table): Move to...
11549 * src/lalr.c (lalr): Don't call it...
11550 * src/LR0.c (generate_states): do it.
11551 * src/LR0.h (first_state): Remove, only the table is used.
11553 2001-12-10 Akim Demaille <akim@epita.fr>
11555 * src/LR0.h (first_shift, first_reduction): Remove.
11556 * src/lalr.c: Don't use first_shift: find shifts through the
11559 2001-12-10 Akim Demaille <akim@epita.fr>
11561 * src/LR0.c: Attach shifts to states as soon as they are
11563 * src/lalr.c (set_state_table): Instead of assigning shifts to
11564 state, just assert that the mapping was properly done.
11566 2001-12-10 Akim Demaille <akim@epita.fr>
11568 * src/LR0.c (insert_start_shift): Rename as...
11569 (insert_start_shifting_state): this.
11570 (insert_eof_shifting_state, insert_accepting_state): New.
11571 (augment_automaton): Adjust.
11572 Better locality of the variables.
11573 When looking if the start_symbol is shifted from the initial
11574 state, using `while (... symbol != start_symbol ...)' sounds
11575 better than `while (... symbol < start_symbol ...)': If fail
11576 to see how the order between symbols could be relevant!
11578 2001-12-10 Akim Demaille <akim@epita.fr>
11580 * src/getargs.h: Don't declare `spec_name_prefix' and
11581 `spec_file_prefix', declared by src/files.h.
11582 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11583 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11584 * src/output.c (prepare): Adjust.
11585 * src/reader.c (symbols_output): Likewise.
11586 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11588 2001-12-10 Akim Demaille <akim@epita.fr>
11590 * src/muscle_tab.c (muscle_init): NULL is a better default than
11593 2001-12-10 Akim Demaille <akim@epita.fr>
11595 * src/reader.c (reader): Calling symbols_output once is enough.
11597 2001-12-10 Akim Demaille <akim@epita.fr>
11599 Now that states have a complete set of members, the linked list of
11600 reductions is useless: just fill directly the state's reductions
11603 * src/state.h (struct reductions): Remove member `number' and
11605 * src/LR0.c (first_reduction, last_reduction): Remove.
11606 (save_reductions): Don't link the new reductions, store them in
11608 * src/lalr.c (set_state_table): No need to attach reductions to
11609 states, it's already done.
11610 * src/output.c (output_actions): No longer free the shifts, then
11611 the reductions, then the states: free all the states and their
11614 2001-12-10 Akim Demaille <akim@epita.fr>
11616 * src/options.c (OPTN, DRTV, BOTH): New.
11617 (option_table): Use them.
11619 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11620 the job of system.h.
11621 * src/options.c: Don't include stdio.h and xalloc.h for the same
11624 2001-12-10 Akim Demaille <akim@epita.fr>
11626 * src/output.c (output, prepare): Make sure the values of the
11627 muscles `action' and `prologue' are 0-terminated.
11629 2001-12-10 Akim Demaille <akim@epita.fr>
11631 Clean up GCC warnings.
11633 * src/reader.c (copy_action): `buf' is not used.
11634 (parse_skel_decl): Be static.
11635 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11636 * src/options.h (create_long_option_table): Have a real prototype.
11637 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11638 (hash_delete_at): Return const void *.
11639 Adjust casts to preserve the const.
11641 2001-12-10 Akim Demaille <akim@epita.fr>
11643 * configure.in: Require 2.52g.
11644 M4 is not needed, but AUTOM4TE is.
11645 * m4/m4.m4: Remove.
11646 * tests/Makefile.am: Adjust.
11648 2001-12-10 Akim Demaille <akim@epita.fr>
11650 One structure for states is enough, even though theoretically
11651 there are LR(0) states and LALR(1) states.
11653 * src/lalr.h (state_t): Remove.
11654 (state_table): Be state_t **, not state_t *.
11655 * src/state.h (core, CORE_ALLOC): Rename as...
11656 (state_t, STATE_ALLOC): this.
11657 Add the LALR(1) members: shifts, reductions, errs.
11658 * src/LR0.c (state_table): Rename as...
11659 (state_hash): this, to avoid name clashes with the global
11661 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11662 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11664 2001-12-10 Akim Demaille <akim@epita.fr>
11666 Bison dumps core on bash.y.
11667 Reported by Pascal Bart.
11669 * src/warshall.c (bitmatrix_print): New.
11671 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11672 j must be the outer loop.
11673 * tests/regression.at (Broken Closure): New.
11675 2001-12-05 Akim Demaille <akim@epita.fr>
11677 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
11679 Reported by Peter Hamorsky.
11681 2001-12-05 Akim Demaille <akim@epita.fr>
11683 * src/conflicts.c (err_table): Remove.
11684 (resolve_sr_conflict): Adjust.
11685 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
11687 (state_t.reductions, state_t.shifts): this.
11689 2001-12-05 Akim Demaille <akim@epita.fr>
11691 * src/reduce.c (reduce_grammar_tables): No longer disable the
11692 removal of useless rules via CPP but via `if (0)', so that the
11693 compiler still check the code is valid.
11694 For instance, it should have noticed `rline' no longer exists: use
11695 the `line' member of rule_t.
11696 * src/gram.c (dummy, rline): Remove, unused.
11698 2001-12-05 Akim Demaille <akim@epita.fr>
11700 * src/output.c (pack_vector): Use assert, not berror.
11701 * src/main.c (berror): Remove, unused.
11703 2001-12-05 Akim Demaille <akim@epita.fr>
11705 New experimental feature: if --verbose --trace output all the
11706 items of a state, not only its kernel.
11708 * src/print.c (print_core): If `trace_flag', then invoke closure
11709 before outputting the items of the state (print_core is no longer
11710 a correct name them).
11711 (print_results): Invoke new_closure/free_closure if needed.
11713 2001-12-05 Akim Demaille <akim@epita.fr>
11715 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
11716 * src/closure.c, src/closure.h (itemsetsize): Rename as...
11717 (nitemset): for consistency with the rest of the project.
11719 2001-12-05 Akim Demaille <akim@epita.fr>
11721 * src/closure.c (print_closure): Improve.
11722 (closure): Use it for printing input and output.
11724 2001-12-05 Akim Demaille <akim@epita.fr>
11726 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11727 indexed by nonterminals.
11729 2001-12-05 Akim Demaille <akim@epita.fr>
11731 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
11733 * src/warshall.h: Remove accidental duplication of the content.
11735 2001-12-05 Akim Demaille <akim@epita.fr>
11737 * src/closure.c (set_fderives): De-obfuscate.
11739 2001-12-05 Akim Demaille <akim@epita.fr>
11741 * src/closure.c (print_firsts, print_fderives): De-obfuscate.

11747 2001-12-05 Akim Demaille <akim@epita.fr>
11749 * src/output.c (action_row): De-obfuscate
11750 using the good o' techniques: arrays not pointers, variable
11751 locality, BITISSET, RESETBIT etc.
11753 2001-12-05 Akim Demaille <akim@epita.fr>
11755 Pessimize the code to simplify it: from now on, all the states
11756 have a valid SHIFTS, which NSHIFTS is possibly 0.
11758 * src/LR0.c (shifts_new): Be global and move to..
11759 * src/state.c, src/state.h: here.
11760 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
11761 * src/print_graph: Adjust.
11763 2001-12-05 Akim Demaille <akim@epita.fr>
11765 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
11766 * src/conflicts.c: Use it.
11767 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11768 incorrectly ``simplified''.
11770 2001-12-05 Akim Demaille <akim@epita.fr>
11772 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11773 using the good o' techniques: arrays not pointers, variable
11774 locality, BITISSET, RESETBIT etc.
11776 2001-12-05 Akim Demaille <akim@epita.fr>
11778 * src/state.h (SHIFT_SYMBOL): New.
11779 * src/conflicts.c: Use it to deobfuscate.
11781 2001-12-05 Akim Demaille <akim@epita.fr>
11783 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
11784 (print_reductions): De-obfuscate using the good o' techniques:
11785 arrays not pointers, variable locality, BITISSET.
11787 2001-12-05 Akim Demaille <akim@epita.fr>
11789 * src/conflicts.c (print_reductions): Arrays, not pointers.
11792 2001-12-05 Akim Demaille <akim@epita.fr>

11800 2001-12-05 Akim Demaille <akim@epita.fr>
11802 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11804 2001-12-05 Akim Demaille <akim@epita.fr>
11806 * src/conflicts.c (print_reductions): Improve variable locality.
11808 2001-12-05 Akim Demaille <akim@epita.fr>
11810 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
11811 * src/lalr.c: Use them.
11813 2001-12-05 Akim Demaille <akim@epita.fr>
11815 * src/LR0.c (augment_automaton): Formatting changes.
11816 Better variable locality.
11818 2001-12-05 Akim Demaille <akim@epita.fr>
11820 * src/lalr.c (matrix_print): New.
11821 (transpose): Use it.
11822 Use arrays instead of pointers.
11824 2001-12-05 Akim Demaille <akim@epita.fr>
11826 * src/lalr.c (maxrhs): Move to...
11827 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
11828 * src/lalr.c (build_relations): Adjust.
11830 2001-12-05 Akim Demaille <akim@epita.fr>
11832 * src/lalr.c (transpose): Free the memory allocated to the
11833 argument, as it is replaced by the results by the unique caller.
11834 (build_relations): Merely invoke transpose: it handles the memory
11836 Improve variable locality.
11837 Avoid variables used as mere abbreviations.
11838 (compute_lookaheads): Use arrays instead of pointers.
11840 2001-12-05 Akim Demaille <akim@epita.fr>
11842 * src/lalr.c (initialize_F): Improve variable locality.
11843 Avoid variables used as mere abbreviations.
11845 2001-12-05 Akim Demaille <akim@epita.fr>
11847 * src/derives.c (print_derives): Display the ruleno.
11848 * src/lalr.c (initialize_F, transpose): Better variable locality
11849 to improve readability.
11850 Avoid variables used as mere abbreviations.
11852 2001-12-05 Akim Demaille <akim@epita.fr>
11854 * src/lalr.c (traverse): Use arrays instead of pointers.
11856 2001-12-05 Akim Demaille <akim@epita.fr>
11858 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11859 the handling of squeue.
11860 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11862 2001-12-05 Akim Demaille <akim@epita.fr>
11864 Because useless nonterminals are now kept alive (instead of being
11865 `destroyed'), we now sometimes examine them, and store information
11866 related to them. Hence we need to know their number, and adjust
11867 memory allocations.
11869 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11871 * src/LR0.c (allocate_itemsets): The memory allocated to
11872 `symbol_count' was used for two different purpose: once to count
11873 the number of occurrences of each symbol, and later reassigned to
11874 `shift_symbol', containing the symbol that can be shifted from a
11876 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11878 (new_itemsets): Allocate `shift_symbol' here.
11879 (allocate_itemsets): symbol_count includes useless nonterminals.
11880 Make room for them.
11881 (free_storage): Use `free', not `XFREE', for pointers that cannot
11884 2001-12-05 Akim Demaille <akim@epita.fr>
11886 * src/nullable.c (set_nullable): Deobfuscate the handling of
11888 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11890 2001-12-05 Akim Demaille <akim@epita.fr>
11892 * src/gram.c, src/gram.h (ritem_print): New.
11893 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
11894 (This useless function was defined only to work around VMS linkers
11895 that can't handle compilation units with variables only).
11896 * src/reduce.c (dump_grammar): Use it to trace the construction of
11899 2001-12-04 Paul Eggert <eggert@twinsun.com>
11901 * src/bison.simple (union yyalloc): Change member names
11902 to be the same as the stack names.
11903 (yyparse): yyptr is now union yyalloc *, not char *.
11904 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
11905 and may generate better code on some machines.
11906 (yystpcpy): Use prototype if __STDC__ is defined, not just
11907 if __cplusplus is defined.
11909 2001-11-30 Akim Demaille <akim@epita.fr>
11911 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
11912 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
11913 Gettext doesn't compile cleanly, and dies with -Werror.
11914 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
11915 Include WARNING_CFLAGS here.
11916 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
11917 before being defined.
11919 2001-11-27 Paul Eggert <eggert@twinsun.com>
11921 * lib/quotearg.h (quotearg_n, quotearg_n_style):
11922 First arg is int, not unsigned.
11923 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
11924 (SIZE_MAX, UINT_MAX): New macros.
11925 (quotearg_n_options): Abort if N is negative.
11926 Avoid overflow check on hosts where size_t is 64 bits and int
11927 is 32 bits, as overflow is impossible there.
11928 Fix off-by-one typo that caused unnecessary reallocation.
11930 2001-11-29 Paul Eggert <eggert@twinsun.com>
11932 Name space cleanup in generated parser.
11934 * doc/bison.texinfo (Bison Parser): Discuss system headers
11935 and their effect on the user name space.
11937 * src/bison.simple:
11938 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
11939 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
11940 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
11942 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
11943 on user names when possible.
11945 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
11946 Simplify test for whather <alloca.h> exists.
11948 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
11950 (<stdio.h>): Include if YYDEBUG.
11952 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
11953 ! defined (yyoverflow) && ! defined (yymemcpy).
11955 (yymemcpy, yyparse): Rename local variables as needed so that
11956 they all begin with 'yy'.
11958 (yystrlen, yystpcpy): New functions.
11960 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
11963 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
11964 instead of relying on string.h functions. Use YYSTACK_ALLOC
11965 and YYSTACK_FREE instead of malloc and free.
11967 2001-11-30 Akim Demaille <akim@epita.fr>
11969 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
11970 before their first uses.
11971 (YYBISON, YYPURE): Move to the top of the output.
11973 2001-11-30 Akim Demaille <akim@epita.fr>
11975 * tests/reduce.at (Useless Nonterminals): Fix.
11977 2001-11-30 Akim Demaille <akim@epita.fr>
11979 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
11980 if body instead of `;' to pacify GCC's warnings.
11982 2001-11-30 Akim Demaille <akim@epita.fr>
11984 Instead of mapping the LHS of unused rules to -1, keep the LHS
11985 valid, but flag the rules as invalid.

14095 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
14096 s/PFILE1/BISON_HAIRY/.
14097 Adjust dependencies.
14099 2000-11-03 Akim Demaille <akim@epita.fr>
14101 For some reason, this was not applied.
14103 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

14116 (done): Rename as...
14117 (output_files): this.
14118 Use `obstack_save'.
14119 * src/main.c (main): Don't use `atexit' to register `done', since
14120 it no longer has to remove tmp files, just call `output_files'
14121 when there are no errors.
14123 2000-11-02 Akim Demaille <akim@epita.fr>
14125 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

14197 (copy_guard): Adjust.
14199 2000-10-16 Akim Demaille <akim@epita.fr>

14225 2000-10-04 Akim Demaille <akim@epita.fr>

14228 `bison -v' segfaults.
14229 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
14231 * tests/regression.m4: New file.
14232 Include the core of the sample provided by Piotr Gackiewicz.
14233 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
14236 2000-10-04 Akim Demaille <akim@epita.fr>

14253 2000-10-02 Akim Demaille <akim@epita.fr>
14255 * src/derives.c, src/print.c, src/reduce.c: To ease the
14256 translation, move some `\n' out of the translated strings.
14258 2000-10-02 Akim Demaille <akim@epita.fr>
14260 The location tracking mechanism is precious for parse error
14261 messages. Nevertheless, it is enabled only when `@n' is used in
14262 the grammar, which is a different issue (you can use it in error
14263 message, but not in the grammar per se). Therefore, there should
14264 be another means to enable it.
14266 * src/getargs.c (getargs): Support `--locations'.
14267 (usage): Report it.
14268 * src/getargs.h (locationsflag): Export it.
14269 * src/lex.c (percent_table): Support `%locations'.
14270 * src/reader.c (yylsp_needed): Remove this variable, now replaced
14271 with `locationsflag'.
14272 * doc/bison.texinfo: Document `--locations' and `%locations'.
14274 * tests/calc.m4: Test it.
14276 For regularity of the names, replace each
14277 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
14278 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
14279 In addition replace each `flag' with `_flag'.
14281 2000-10-02 Akim Demaille <akim@epita.fr>
14283 Also test parse error messages, including with YYERROR_VERBOSE.
14285 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
14287 Use it to check the computations.
14288 Use it to check `nonassoc' is honored.
14289 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
14290 `--yyerror-verbose'.
14291 (_AT_CHECK_CALC): Adjust to this option.

14294 2000-10-02 Akim Demaille <akim@epita.fr>
14296 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14297 the latter demonstrates a flaw in the handling of non debugging
14298 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14299 was used in order to simplify:
14315 unfortunately this leads to a CPP conflict when
14316 `--name-prefix=foo' is used since it produces `#define yydebug
14319 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14320 (YYDPRINTF): New macro.
14322 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
14324 Also test `--verbose', `--defines' and `--name-prefix'.

14328 Improve the readability of the produced parsers.
14330 * src/bison.s1: Formatting changes.
14331 Improve the comment related to the `$' mark.
14332 (yydefault): Don't fall through to `yyresume': `goto' there.
14333 * src/output.c (output_parser): When the `$' is met, skip the end
14335 New variable, `number_of_dollar_signs', to check there's exactly
14336 one `$' in the parser skeleton.
14338 2000-10-02 Akim Demaille <akim@epita.fr>
14340 * lib/xstrdup.c: New file, from the fileutils.
14341 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
14342 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
14343 instead of strlen + xmalloc + strcpy.
14344 * src/symtab.c (copys): Remove, use xstrdup instead.
14346 2000-10-02 Akim Demaille <akim@epita.fr>
14348 * src/gram.h (associativity): New enum type which replaces the
14349 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
14350 `right_assoc', `left_assoc' and `non_assoc'.
14351 Adjust all dependencies.
14352 * src/reader.c: Formatting changes.
14353 (LTYPESTR): Don't define it, use it as a literal in
14354 `reader_output_yylsp'.
14355 * src/symtab.h (symbol_class): New enum type which replaces the
14356 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
14357 `sunknown', `stoken and `snterm'.
14359 2000-10-02 Akim Demaille <akim@epita.fr>
14361 * src/getargs.c (fixed_outfiles): Rename as...
14362 (yaccflag): for consistency and accuracy.
14363 Adjust dependencies.
14365 2000-10-02 Akim Demaille <akim@epita.fr>
14367 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14368 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14369 difficult and introduced a lot of core dump. It turns out that
14370 Bison used an implementation of `xmalloc' based on `calloc', and
14371 at various places it does depend upon the initialization to 0. I
14372 have not tried to isolate the pertinent places, and all the former
14373 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14374 someone should address this issue.
14376 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
14377 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

14387 * src/system.h: Include `assert.h'.
14389 2000-10-02 Akim Demaille <akim@epita.fr>
14391 * src/state.h (nstates, final_state, first_state, first_shift)
14392 (first_reduction): Move their exportation from here...
14393 * src/LR0.h: to here.
14394 Adjust dependencies.
14395 * src/getargs.c (statisticsflag): New variable.
14396 Add support for `--statistics'.
14397 Adjust dependencies.
14399 Remove a lot of now useless `extern' statements in most files.
14401 2000-10-02 Akim Demaille <akim@epita.fr>
14403 * src/LR0.h: New file.
14406 2000-10-02 Akim Demaille <akim@epita.fr>

14433 Propagate its inclusion.
14434 * src/reduce.c: Topological sort and other formatting changes.
14435 (bool, TRUE, FALSE): Move their definition to...
14436 * src/system.h: here.
14438 2000-10-02 Akim Demaille <akim@epita.fr>
14440 * src/files.c: Formatting changes.
14441 (tryopen, tryclose, openfiles): Rename as...

14467 * src/lalr.c: Formatting changes, topological sorting etc.
14469 2000-10-02 Akim Demaille <akim@epita.fr>
14471 * src/output.c (token_actions): Introduce a temporary array,
14472 YYDEFACT, that makes it possible for this function to use
14473 output_short_table.
14475 2000-10-02 Akim Demaille <akim@epita.fr>
14477 `user_toknums' is output as a `short[]' in `output.c', while it is
14478 defined as a `int[]' in `reader.c'. For consistency with the
14479 other output tables, `user_toknums' is now defined as a table of

14523 * src/system.h: Define PARAMS.

14525 purpose of config.h. system.h must not try to fix wrong
14526 definitions in config.h.

14783 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

15509 (parse_percent_token): Replaced if-else statement with percent_table.
15510 (parse_percent_token): Added % declarations as another
15511 way to specify the flags -n, -l, and -r. Also added hooks for
15512 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
15513 major changes to files.c.
