1 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
3 * src/getargs.c (usage): Back out yesterday's modification of the
4 --help output so that we don't have to wait for translation before
7 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
10 Problem reported by Akim Demaille.
12 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
14 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
16 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
18 * data/yacc.c (yy_reduce_print): Omit trailing white space in
19 generated source code. Problem reported by Frans Englich in
20 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
22 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
24 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
25 shell, not within 'make', so that 'make' by an ordinary builder
26 (using GNU make) does not worry about configuring gzip. This also
27 works around a bug reported independently by Keith Thompson and by
28 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
29 stderr rather than stdout, messing up the build logs.
31 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
33 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
34 to make sure that YYID will never be unused. This fixes a 'make
35 maintainer-check' failure caused by the recent changes to the 'Trivial
36 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
38 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
40 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
42 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
43 state before an empty RHS is always resolved here. Only the location
44 of that state is guaranteed to be resolved, and that's enough. This
45 fixes the remaining bug reported by Derek M. Jones in
46 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
47 * tests/glr-regression.at (Uninitialized location when reporting
48 ambiguity): Test the above case.
49 Also, the embedded comments in this test case claim it checks the case
50 of an empty RHS that has inherited the initial location. However, the
51 corresponding LHS was already resolved, so yyresolveLocations didn't
52 actually have reason to modify it. Fix this by forcing
53 nondeterministic operation at the beginning of the parse.
55 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
57 * data/c.m4 (b4_yy_symbol_print_generate):
58 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
59 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
60 of the bugs reported today by Derek M Jones in
61 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
62 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
63 defined to be a type name without parens or brackets.
64 (Location Type): Similarly for YYLTYPE.
65 * tests/regression.at (Trivial grammars): Put in a test for this
66 bug that will be caught by 'make maintainer-check' (though not,
67 alas, by 'make check' unless your compiler is picky).
69 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
72 * configure.ac (AC_INIT): Likewise.
74 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
76 * data/glr.c (yyreportTree): Make room in yystates for the state
77 preceding the RHS. This fixes the segmentation fault reported by Derek
79 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
80 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
81 to the user. Reported for yyreportTree by Derek M. Jones later in the
83 * THANKS: Add Derek M. Jones.
84 Update my email address.
85 Fix typo in Steve Murphy's name.
87 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
89 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
90 checking against YYLAST that caused the parser to miss a potential
91 alternative in its diagnostic.
92 Problem reported by Maria Jose Moron Fernandez in
93 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
94 * data/lalr1.cc (yysyntax_error_): Likewise.
95 * data/yacc.c (yysyntax_error): Likewise.
96 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
97 tokens, in case we run into an older C compiler.
98 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
99 Use them to check for the off-by-one error fixed above.
101 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
102 YYSIZE_T, not size_t.
103 * tests/regression.at (Trivial grammars): New test, to catch
104 the error fixed by the above patch.
106 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
108 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
110 Reported by Steve Murphy.
112 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
114 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
115 * data/glr.cc: b4_location_flag is now b4_locations_flag.
117 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
119 Implement --trace=m4.
120 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
121 * src/output.c (output_skeleton): When set, pass -dV to m4.
123 Factor the handling of flags in m4.
124 * src/output.c (prepare): Rename the muscle names debug, defines,
125 error_verbose to debug_flag, defines_flag, error_verbose_flag.
127 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
128 Use b4_define_flag_if to define other b4_FLAG_if macros.
129 (b4_location_if): As a consequence, rename as...
130 (b4_locations_if): this, for consistency.
131 Adjust all the skeletons.
133 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
135 * etc/bench.pm: Shorten bench names.
137 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
139 * src/output.h, src/output.c (error_verbose): Move to...
140 * src/getargs.h, src/getargs.c: here.
144 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
146 * data/c.m4 (b4_copyright): Put the special exception for Bison
147 skeletons here, so we don't have to put it in each skeleton. All
148 uses changed. Suggested by Akim Demaille. Also, wrap the
149 copyright notice, in case it is longer than 80 columns. Replace
150 comma by newline after title.
152 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
154 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
155 incompatibility, not a bug. Mention that it wasn't fixed as of
158 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
160 * examples/extexi: Enforce the precedence of concatenation over
162 Reported by Tommy Nordgren.
164 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
166 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
167 with the member "token".
168 Reported by Martin Nylin.
170 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
172 * data/glr.c: Switch to Bison 2.2 special-exception language in
173 the copyright notice. Use more-regular format for titles and
175 * data/glr.cc: Likewise.
176 * data/location.cc: Likewise.
177 * data/yacc.cc: Likewise.
178 * doc/bison.texinfo (Conditions): Document this.
179 * NEWS: likewise. Upgrade version to 2.2.
181 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
183 * data/glr.cc: Remove dead code.
185 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
187 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
188 that variable and the line breaks the bootstrap. Problem reported
191 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
193 * doc/bison.texinfo (Multiple start-symbols): New.
195 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
197 * etc/README, etc/bench.pl: New.
199 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
201 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
203 Reported by Mickael Labau.
204 * tests/input.at (Torturing the Scanner): Test it.
206 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
208 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
209 Problem reported by Bob Rossi.
211 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
213 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
214 and didn't really work.
215 For the index, use @ifnotinfo, not @iftex.
216 Minor cleanups of spacing and terminology.
218 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
220 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
221 of AT_NAME_PREFIX when %name-prefix is not used.
223 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
225 Apply --prefix to C++ skeletons too: they change the namespace.
226 The test suite already exercize these cases.
227 * data/c++.m4 (b4_namespace): New.
228 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
229 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
230 * data/yacc.c, data/glr.c: Remove a useless `[]'.
231 * doc/bison.texinfo: Document it.
232 (Option Cross Key): Use @multitable in all formats. It looks
233 nicer, even in TeX outputs.
234 (Rules): Use the same code whatever the output type is.
235 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
236 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
237 * tests/calc.at: Use it, instead of hard coding `yy'.
239 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
241 * TODO: Remove dead items.
243 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
245 * doc/FAQ: Remove, merged into...
246 * doc/bison.texinfo (FAQ): this.
247 * doc/Makefile.am (EXTRA_DIST): Adjust.
249 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
251 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
253 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
254 * doc/bison.texinfo (Calc++ Scanner): Use it.
256 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
258 Fix two nits reported by twlevo, plus one more that I discovered.
260 * src/assoc.h (assoc_to_string): Give a name to the arg, as
261 this is the usual Bison style.
262 * src/location.h (location_print): Likewise.
264 * src/reader.h (token_name): Likewise.
266 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
268 Fix some nits reported by twlevo.
269 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
270 and "POSIX". Use more-modern syntax for URLs. Mention C++
271 and ask for Java. Don't hardwire OS version numbers. Add
273 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
274 * src/conflicts.c (solved_conflicts_obstack): Now static.
276 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
278 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
279 page. Say "you can use it" not "you may use it" as on the web page;
280 we're describing capabilities not granting permission.
282 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
284 * data/glr.c (yyresolveLocations): Rename local variables to avoid
285 shadowing warnings. Use usual patter for iterating through RHS.
286 * tests/glr-regression.at
287 (Uninitialized location when reporting ambiguity):
288 Modify yylex so that it uses its argument, rather than trying
289 to rely on ARGSUSED (which doesn't work for gcc with warnings).
290 const char -> char const.
292 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
293 Don't use tabs inside commands; it messes up 'ps'.
294 Problem reported by twlevo.
296 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
298 * tests/glr-regression.at (Uninitialized location when reporting
299 ambiguity): New test case.
300 * data/glr.c (yyresolveLocations): New function, which uses
302 (yyresolveValue): Invoke yyresolveLocations before reporting an
304 * doc/bison.texinfo (Default Action for Locations): Note
305 YYLLOC_DEFAULT's usage for ambiguity locations.
306 (GLR Semantic Actions): Cross-reference those notes.
308 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
310 * tests/glr-regression.at (Leaked semantic values when reporting
311 ambiguity): Remove unnecessary union and type declarations.
312 (Leaked lookahead after nondeterministic parse syntax error): New test
314 * data/glr.c (yyparse): Check for zero stacks remaining before
315 attempting to shift the lookahead so that you don't lose it.
317 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
319 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
320 * tests/glr-regression.at (Leaked semantic values when reporting
321 ambiguity): New test case.
322 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
323 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
324 now unnecessary yystackp parameter.
325 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
326 destructors can be called.
328 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
329 in existing testcases.
331 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
333 Don't leak semantic values for parent RHS when a user action cuts the
334 parser, and clean up related code a bit.
335 * tests/glr-regression.at (Leaked merged semantic value if user action
336 cuts parse): Rename to...
337 (Leaked semantic values if user action cuts parse): ... this. Add check
338 for leaked parent RHS values.
339 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
340 between an unresolved state (non-empty chain of semantic options) and
341 an incomplete one (signaled by an empty chain).
342 (yyresolveStates): Document the interface. Move all manipulation of a
343 successfully or unsuccessfully resolved yyGLRState to...
344 (yyresolveValue): ... here so that yyresolveValue always leaves a
345 yyGLRState with consistent data and thus is easier to understand.
346 Remove the yyvalp and yylocp parameters since they are always just
347 taken from the yys parameter. When reporting a discarded merged value
348 in debugging output, note that it is incompletely merged. Document the
350 (yyresolveAction): If resolving any of the RHS states fails, destroy
351 them all rather than leaking them. Thus, as long as user actions are
352 written to clean up the RHS correctly, yyresolveAction always cleans up
353 the RHS of a semantic option. Document the interface.
355 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
357 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
358 led to a segmentation fault in GNU Pascal. Problem reported
361 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
363 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
364 mid-rule action inside a nonterminal symbol in order to declare a
365 destructor for its semantic value.
367 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>

371 __cplusplus && ! defined _STDLIB_H && !
372 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
373 defined free))]: Include <stdlib.h> rather than rolling our own
374 declarations of malloc and free, to avoid problems with
375 incompatible declarations (using 'throw') C++'s stdlib.h. This
376 should fix Debian bug 340012

388 * NEWS: Version 2.1a.
389 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
390 since C99 requires this.
392 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
394 * m4/c-working.m4: New file.
395 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
397 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
399 * Makefile.maint: Merge from coreutils.
401 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
403 More portability fixes for problems summarized by Nelson H. F. Beebe.
405 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
406 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
407 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC

414 More portability fixes for problems summarized by Nelson H. F. Beebe.
416 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
417 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
419 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
420 nodist_PROGRAMS, since we don't need to actually compile the
421 example if we're just doing a plain 'make'. This avoids bothering
422 the installer unnecessarily about problems due to weird C++

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

444 '#include <map>' works and that you can apply ++ to iterators.
446 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
448 Work around portability problems summarized by Nelson H. F. Beebe in

451 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
452 that '#include <string>' works.
454 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
455 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
456 "warning: sorry: semantics of inline function static data `const
457 unsigned char translate_table[262]' are wrong (you'll wind up with

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

470 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
472 During deterministic GLR operation, user actions should be able to
473 influence the parse by changing yychar. To make this easier to fix and
474 to make glr.c easier to evolve in general, don't maintain yytoken in
475 parallel with yychar; just compute yytoken when needed.
476 * tests/glr-regression.at (Incorrect lookahead during deterministic
477 GLR): Check that setting yychar in a user action has the intended

480 (yyclearin): Don't set *yytokenp.
481 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
482 yychar rather than *yytokenp to determine the current lookahead.
483 Compute yytoken locally when needed.
484 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
487 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
488 after `--report' documentation.

499 all the test at once. This makes the output easier to read in the
502 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
503 got from <http://bro-ids.org/download.html>. The bug is that
504 when two actions appeared in succession, the second one was
505 scanned before the first one was added to the grammar rule
506 as a midrule action. Bison then output the incorrect warning
507 "parse.y:905.17-906.36: warning: unused value: $3".
508 * src/parse-gram.y (BRACED_CODE, action): These are no longer
509 associated with a value.
510 (rhs): Don't invoke grammar_current_rule_action_append.
511 (action): Invoke it here instead.
512 * src/reader.c (grammar_midrule_action): Now extern.
513 (grammar_current_rule_action_append): Don't invoke
514 grammar_midrule_action; that is now the scanner's job.
515 * src/reader.h (last_string, last_braced_code_loc):
516 (grammar_midrule_action): New decls.

770 In the yychar entry, remove mention of the local yychar case (pure
771 parser) since this is irrelevant information when writing semantic
772 actions and since it's already discussed in `Bison Symbols' where
773 yychar is otherwise described as an external variable.
774 In the yychar entry, don't call it the `current' look-ahead since it
775 isn't when semantic actions are deferred.
776 In the yychar and yyclearin entries, add note about deferred semantic
778 Add yylloc and yylval entries discussing look-ahead usage.
779 (Look-Ahead Tokens): When discussing yychar, don't call it the

802 members to store the current lookahead to be used by the deferred
804 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
805 from which the RHS is taken. Set the lookahead members of the new

834 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
836 * data/glr.c (yyresolveValue): When merging semantic options, if at
837 least one user action succeeds but a later one cuts the parse, then
838 destroy the semantic value before returning rather than leaking it.
839 (yyresolveStates): If a user action cuts the parse and thus
840 yyresolveValue fails, ignore the (unset) semantic value rather than
841 corrupting the yyGLRState, and empty the semantic options list since
842 the user actions should have called all necessary destructors.
843 Simplify code with YYCHK.
844 * tests/glr-regression.at (Corrupted semantic options if user action
845 cuts parse): New test case.
846 (Undesirable destructors if user action cuts parse): New test case.

1144 sed out the final state number.
1146 Work around portability problem on Solaris 10: flex-generated
1147 files include <stdio.h> before <config.h>, which messes up
1148 because the latter defines __EXTENSIONS__. Address the problem
1149 by creating two new little files that include <config.h> first,
1150 then include the flex-generated files. Rewrite everyone else

1228 it's no longer just a file.
1229 * data/glr.c: Grant a special exception for C GLR parsers, that
1230 reads like the already-existing exception for C LALR(1) parsers.

1488 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
1489 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
1491 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
1493 Undo the parts of the unlocked-I/O change that substituted
1494 putc or puts for printf. This might hurt performance a bit,
1495 but some people prefer the printf style.
1496 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
1497 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

1518 unused-variable warnings.
1520 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

1524 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
1526 Use unlocked I/O for a minor performance improvement on hosts like
1527 GNU/Linux and Solaris that support unlocked I/O. The basic idea
1528 is to use the gnlib unlocked-io module, and to prefer putc and
1529 puts to printf when either will work (since the latter doesn't
1530 come in an unlocked flavor).
1531 * bootstrap (gnulib_modules): Add unlocked-io.

1550 * src/system.h: Include unlocked-io.h rather than stdio.h.
1552 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

1602 to allow support for non-posix systems. This is a no-op function
1605 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
1606 handle the lack of pipe/fork functionality on non-posix systems.

1645 (parser::semantic_value): Now a full definition instead of an
1646 indirection to YYSTYPE.

1690 local variables whose names begin with 'yy'.
1691 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1692 Trivial changes from Joel E. Denny.
1694 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1696 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1697 don't use alloca any more.
1699 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1700 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
1701 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

1712 This works a bit better with glibc, if user code has already included

1731 (yysyntax_error): New function.
1732 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if

1734 Instead, reallocate buffers twice as big each time, so that
1735 we waste at most half the allocated memory. Start with a small
1736 (128-byte) buffer that will suffice in most cases anyway.
1737 Use yysyntax_error to do most of the work.
1739 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1740 yynerrs is the number of errors reported, not the number of

1749 2005-09-19 Akim Demaille <akim@epita.fr>
1751 Remove the traits, failed experiment.
1752 It never proved useful, and anyway because of the current
1753 definition, it was not possible to have several specialization of
1754 this traits, making it useless.
1755 * data/lalr1.cc (yy:traits): Remove.
1756 Inline its definitions in the parser class.
1758 2005-09-19 Akim Demaille <akim@epita.fr>

1783 is not defined. This is an awful hack, but it's enough for now.
1784 All callers changed.
1785 * tests/glr-regression-at (make_value): Args are const pointers now,
1786 to avoid GCC warning.
1787 (Duplicated user destructor for lookahead): New test. Currently
1788 skipped. It fails on my host but I'm not sure it'll always fail.
1790 2005-09-16 Akim Demaille <akim@epita.fr>
1792 * src/symtab.h (struct symbol): Declare the printer and destructor
1793 as const, to avoid accidental calls to free.

1810 * data/lalr1.cc (yylex_): Remove, inline its code.
1811 (yyreport_syntax_error_): Remove, replaced by...
1812 (yysyntax_error_): this which returns a string and leaves to the
1813 caller the call to the users' error function.
1814 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
1815 Move from members of the parser object...
1816 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

1840 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1841 do anything if $@ exists. This reverts part of the 2005-07-07
1844 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1846 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1847 contains obsolete information and isn't worth distributing as a
1848 separate file anyway.
1849 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1850 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

1857 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
1858 Suggested by twlevo@xs4all.nl.
1860 * data/glr.c (YYCHK1): Do not assume YYE is in range.

1862 Problem reported by twlevo@xs4all.nl.
1864 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1865 standards. Use "file name" or "file" or "name", depending on
1867 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1868 not to hack/foo.tab.c.
1869 (Calc++ Top Level): 2nd arg of main is not const.
1870 * data/glr.c: b4_filename -> b4_file_name.

1954 the above change. This changes the debug output format slightly.
1956 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
1957 reported by Joel E. Denny in
1958 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
1960 * tests/glr-regression.at (Duplicate representation of merged trees):
1961 New test, from Joel E. Denny in:
1962 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
1963 * THANKS: Add Joel E. Denny.
1965 * configure.ac (AC_INIT): Bump to 2.0c.
1967 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
1969 * NEWS: Version 2.0b.
1971 * Makefile.am (SUBDIRS): Put examples before tests, so that
1972 "make check" doesn't finish with "All 1 tests passed".
1974 * tests/regression.at (Token definitions): Don't rely on
1975 AT_PARSER_CHECK for data that contains backslashes. It currently
1976 uses 'echo', and 'echo' isn't portable if its argument contains
1977 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1978 that the byte '\0xff' is not printable in the C locale; it is,
1979 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1980 not printable, so use '\0x81' to test.
1982 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1983 version of GCC, since the macro is used with non-GCC compilers.
1985 Fix core dump reported by Pablo De Napoli in
1986 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1987 * tests/regression.at (Invalid inputs with {}): New test.
1988 * src/parse-gram.y (token_name): Translate type before using
1991 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1992 the user's name space. All uses changed to __attribute__
1994 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1995 Add __attribute__ ((__noreturn__)).
1997 * etc/clcommit: Remove. We weren't using it, and it failed
1998 "make maintainer-distcheck".
1999 * Makefile.maint: Merge from coreutils.
2000 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
2001 (syntax-check-rules): Change list of rules as described below.
2002 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

2012 Use grep -n, to make it easier to find violations.
2013 Use CVS_LIST and CVS_LIST_EXCEPT.
2014 (header_regexp, h_re): Remove.
2016 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
2017 (my-distcheck): Use more-modern GCC flags.
2018 (signatures, %.asc): Remove.
2019 (rel-files, announcement): Remove signatures.
2020 Restore old updating code, even though we don't use it, so
2021 that we're the same as coreutils.
2022 (alpha, beta, major): Depend on news-date-check.
2023 Make the upload commands.
2025 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
2026 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
2027 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.

2032 * tests/sets.at: Likewise.
2034 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
2035 we comment out the Autoconf version number.
2036 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
2037 it's error-prone and "make maintainer-distcheck" rejects it.
2039 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
2040 Indent calls to "error" to pacify "make maintainer-distcheck",
2041 when the calls are not intended to be translated.
2042 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
2044 * src/Makefile.am (DEFS): Use +=, to pacify
2045 "make maintainer-distcheck".
2046 (bison_SOURCES): Add scan-skel.h.
2047 (sc_tight_scope): New rule, from coreutils.
2049 * src/files.c (src_extension, header_extension):
2050 Now static, not extern.
2051 * src/getargs.c (short_options): Likewise.
2052 * src/muscle_tab.c (muscle_table): Likewise.
2053 * src/parse-gram.y (current_class, current_type, current_prec):
2055 * src/reader.c (grammar_end, previous_rule_end): Likewise.
2056 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
2057 * src/main.c (main): Cast bindtextdomain and textdomain calls to
2058 void, to avoid warning when NLS is disabled.
2059 * src/output.c: Include scan-skel.h.
2060 (scan_skel): Remove decl, since scan-skel.h does this.
2062 Indent calls to "error" to pacify "make maintainer-distcheck".
2063 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
2064 * src/reader.h (gram_end, gram_lineno): New decls to pacify
2065 "make maintainer-distcheck".
2066 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
2067 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
2068 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
2069 (skel_lex_destroy, scan_skel): Move these decls to...
2070 * src/scan-skel.h: New file.
2071 * src/uniqstr.c (uniqstr_assert):
2072 Indent calls to "error" to pacify "make maintainer-distcheck".
2074 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
2077 * tests/torture.at: Revamp to avoid misuse of atoi that
2078 "make maintainer-distcheck" complained about.
2080 * examples/extexi (message): Don't print a message more than once,
2081 and omit line-number decoration that makes Emacs compile think
2082 that informative messages are worth worrying about.
2084 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
2086 * configure.ac: Update version number.
2088 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
2090 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
2091 autogenerated by the maintainer.
2092 * examples/calc++/.cvsignore: Add *.yy.
2094 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
2095 * lib/bitset_stats.c (bitset_stats_init): Likewise.
2096 * lib/bitsetv.c (bitsetv_alloc): Likewise.
2098 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
2100 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
2101 from maintainer-distcheck about casting the argument of 'free'.
2103 * NEWS: Mention recent yytname changes.
2104 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
2106 * bootstrap: For translations that have not yet been upgraded to
2107 the new runtime-po domain, prime the pump by extracting the
2108 relevant strings from the obsolete translations. This code can be
2109 removed once the bison-runtime domain has been translated by each
2112 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
2113 now that token names are already quoted.
2115 Fix problem reported by Anthony Heading.
2116 * data/glr.c (YYTOKEN_TABLE): New macro.
2117 (yytname): Define if YYTOKEN_TABLE.
2118 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
2119 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
2120 (YYERROR_VERBOSE): Define the same way the other skeletons do.
2121 * src/output.c (prepare_symbols): Output token_table_flag.
2123 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
2125 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
2126 again if the first call fails.
2128 * data/glr.c (yytnamerr): New function.
2129 (yyreportSyntaxError): Use it to dequote most string literals.
2130 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
2131 with other skeletons. All uses changed.
2132 (yytnameerr_): New function.
2133 (yyreport_syntax_error): Use it to dequote most string literals.
2134 * data/yacc.c (yytnamerr): New function.
2135 (yyerrlab): Use it to decode most string literals.
2136 * doc/bison.texinfo (Decl Summary, Calling Convention):
2137 Clarify quoting convention of yytname.
2138 * src/output.c (prepare_symbols): Quote all names. This undoes
2139 the 2005-04-17 change, which is now accomplished (mostly) via
2140 changes in the parsers as described above.
2141 * tests/regression.at (Token definitions, Web2c Actions):
2142 Undo most 2005-04-17 change here, too.
2144 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
2146 Fix more problems reported by twlevo@xs4all.nl.
2147 * tests/cxx-type.at: Don't pipe output of ./types through sed to
2148 remove trailing spaces. This loses the exit status of ./types,
2149 and isn't needed since ./types shouldn't be emitting trailing
2151 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
2152 as the stack isn't valid in that case.
2154 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
2155 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
2156 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
2157 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
2159 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
2160 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
2161 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
2164 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
2165 overly-picky compilers that reject 'char *foo = "bar";'.
2167 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
2168 to FILE * parameter, not to stderr. This fixes a typo introduced
2169 in the 2005-07-12 change.
2171 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
2172 warnings from GCC 4.
2174 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
2175 (yyglrShiftDefer, yysplitStack):
2176 Remove unused parameters b4_pure_formals. All uses changed.
2177 (yyglrShift): Remove unused parameters b4_user_formals.
2179 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
2181 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
2183 Destructor cleanups and regularization among the three skeletons.
2184 * NEWS: Document the behavior changes.
2185 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
2186 stack before failing, as the cleanup code will do it for us now.
2187 * data/lalr1.cc (yyerrlab): Likewise.
2188 * data/glr.c (yyparse): Pop everything off the stack before
2189 freeing it, so that destructors get called properly.
2190 * data/lalr1.cc (yyreturn): Likewise.
2191 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
2192 This is more consistent.
2193 * doc/bison.texinfo (Destructor Decl): Mention more reasons
2194 why destructors might be called. 1.875 -> 2.1.
2195 (Destructor Decl, Decl Summary, Table of Symbols):
2196 Some English-language cleanups for %destructor.
2197 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
2198 Add output line for destructor of start symbol.
2199 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
2200 because of that same extra output line.
2202 * NEWS: Document minor wording changes in diagnostics of
2203 Bison-generated parsers.
2204 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
2205 Remove unused formals. All uses changed.
2206 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
2207 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
2208 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
2209 Rename yyoverflowab to yyexhaustedlab.
2210 When memory exhaustion occurs during syntax-error reporting,
2211 report it separately rather than in a single diagnostic; this
2213 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
2214 (Memory Exhausted): Renamed from Parser Stack Overflow.
2215 Revamp wording slightly to prefer "memory exhaustion".
2216 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
2218 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
2220 Add i18n support to the GLR skeleton. Partially fix the C++
2221 skeleton; a C++ expert needs to finish this. Remove debugging
2222 msgids; there's little point to having them translated, since they
2223 can be understood only by someone who can read the
2224 (English-language) source code.
2226 Generate runtime-po/bison-runtime.pot automatically, so that we
2227 don't have to worry about garbage getting in that file. We'll
2228 make sure after the next official release that old msgids don't
2230 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
2232 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
2234 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
2235 Fix typos in explanations of the runtime file.
2236 * bootstrap: Change gettext keyword from YYI18N to YY_.
2237 Use standard Makefile.in.in in runtime-po, since we'll arrange
2238 for backward-compatible bison-runtime.po files in a different way.
2239 * data/glr.c (YY_): New macro, from yacc.c.
2240 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2241 Translate messages intended for users.
2242 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
2243 the wording in the other skeletons. We don't know that the memory
2245 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
2246 Use same method that yacc.c uses.
2247 Don't translate debugging messages.
2248 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
2249 it doesn't work (yet), and requires C++ expertise to fix.
2250 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
2251 Move defn to a more logical place, to be consistent with other
2253 Don't translate debugging messages.
2254 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
2255 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
2256 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
2257 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
2259 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
2260 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
2262 * tests/glr-regression.at (Badly Collapsed GLR States):
2264 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2265 yylex should return 0 at EOF rather than aborting.
2267 Improve tests for stack overflow in GLR parser.
2268 Problem reported by twlevo@xs4all.nl.
2269 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
2271 (yyStackOverflow): Just longjmp, but with value 2 so that caller
2272 can handle the problem.
2273 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
2274 (yyparse): New local variable yyresult to record the result.
2275 Use result of setjmp to set it, rather than storing itinto
2277 (yyDone): Remove label.
2278 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
2279 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
2280 if YYABORT is used).
2281 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
2282 yyparse status; put status > 1 into diagnostic.
2283 Check that status==2 works.
2284 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
2285 Use exit status 3 for failure to open (which shouldn't happen).
2287 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
2289 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
2290 1 on syntax error; just let yyparse do its thing.
2291 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
2292 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
2293 (Exploding the Stack Size with Alloca):
2294 (Exploding the Stack Size with Malloc):
2295 Expect exit status 2, not 1, since the parser is supposed to blow
2296 its stack. Problem reported by twlevo@xs4all.nl.
2298 * data/glr.c (yyparse): Don't assume that the initial calls
2299 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
2300 Print a stack-overflow message and fail instead.
2301 Initialize the line-number information before creating the stack,
2302 so that the stack-overflow message can report line zero safely.
2304 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
2306 Fix problems reported by twlevo@xs4all.nl.
2307 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
2308 (yyuserMerge): Provide a default case if b4_mergers is empty.
2309 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
2310 * tests/glr-regression.at
2311 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2312 Add casts to pacify C++ compilers.
2313 * tests/glr-regression.at (Improper merging of GLR delayed action
2314 sets): Declare yylex before using it.
2315 * tests/Makefile.am (maintainer-check-g++): Fix a stray
2316 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
2317 test for valgrind; valgrind is independent of g++.
2318 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
2319 for compatibility with POSIX 1003.1-2001 (if running coreutils).
2320 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
2321 Use a destructor, so that we can expand the stack. Change
2322 YYSTYPE to char * so that we can free it. Cast result of malloc.
2324 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2326 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
2327 a valgrind failure. Problem reported by twlevo@xs4all.nl.
2329 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
2331 * PACKAGING: New file, suggested by Bruno Haible and taken from
2332 similar wording in gettext's PACKAGING file.
2333 * NEWS: Mention PACKAGING.
2334 * Makefile.am (EXTRA_DIST): Add PACKAGING.

2338 * NEWS: Document recent i18n improvements.
2339 * bootstrap: Get runtime translations into runtime-po.
2340 Create runtime-po files automatically, if possible.
2341 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
2342 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
2343 does not infringe on the user's name space.
2344 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
2345 * doc/bison.texinfo (Internationalization): Revamp the English
2346 and Texinfo syntax a bit, to try to make it clearer.
2347 (Bison Options, Option Cross Key): Mention --print-localedir.
2348 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
2349 YYENABLE_NLS. Quote a bit more.
2350 * runtime-po/.cvsignore: New file.

2359 * runtime-po/Makevars: Likewise.
2360 * runtime-po/LINGUAS: Likewise.
2361 * runtime-po/de.po: Likewise; we will rely on the translation project
2362 to maintain this, so "bootstrap" should get it.
2363 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
2365 * src/main.c (main): Bind the bison-runtime domain, too.
2367 2005-07-12 Bruno Haible <bruno@clisp.org>
2369 * data/yacc.c: Include <libintl.h> when NLS is enabled.
2370 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
2371 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
2372 * runtime-po: New directory.
2373 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
2374 $(DOMAIN).pot-update rule, so that old messages are never dropped.
2375 * runtime-po/Rules-quot: New file, copied from po/.
2376 * runtime-po/quot.sed: Likewise.
2377 * runtime-po/boldquot.sed: Likewise.

2388 * Makefile.am (SUBDIRS): Add runtime-po.
2389 (aclocaldir, aclocal_DATA): New variables.
2390 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
2392 * src/getargs.c (usage): Document --print-localedir option.
2393 (PRINT_LOCALEDIR_OPTION): New enum item.
2394 (long_options): Add --print-localedir option.
2395 (getargs): Handle --print-localedir option.
2396 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
2397 (Internationalization): New section.
2399 2005-07-12 Akim Demaille <akim@epita.fr>
2401 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
2402 for consistency with the rest of the code.
2403 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
2406 2005-07-12 Akim Demaille <akim@epita.fr>
2408 * src/parse-gram.y: Use %printer instead of YYPRINT.
2410 2005-07-12 Akim Demaille <akim@epita.fr>
2412 * src/symtab.h, src/symtab.c (symbol_print): New.
2413 * src/symlist.h, src/symlist.c (symbol_list_print): New.
2414 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
2416 2005-07-12 Akim Demaille <akim@epita.fr>
2418 * data/glr.c (b4_syncline): Fix (swap) the definitions of
2419 b4_at_dollar and b4_dollar_dollar.
2421 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
2423 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
2424 and Pennello's paper.
2426 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
2428 * data/yacc.c (yyparse): Undo previous patch. Instead,
2429 set yylsp[0] and yyvsp[0] only if the initial action
2430 sets yylloc and yylval, respectively.
2432 * data/yacc.c (yyparse): In the initial action, set
2433 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
2434 This avoids the use of undefined variables if the initial
2435 action does not set yylloc and/or yylval.
2437 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2439 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
2440 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
2441 Remove from CVS. These files are automatically generated.
2442 * examples/extexi: Clarify that this file is now part of Bison,
2443 not GNU M4, and that it works with any POSIX-compatible Awk.
2444 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
2445 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
2446 so that we also get calc++-parser.yy. Geneate it.
2447 Use $(AWK), not gawk, since any conforming Awk will do.
2448 Put comment before action, since older 'make' can't handle comment
2450 $(BUILT_SOURCES): List all built sources, not just some of them.
2451 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
2452 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
2453 $($(calc_sources_generated)): Remove unnecessary test for existence
2454 of target. (This had a shell syntax error anyway; a stray "x".)
2455 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
2457 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
2459 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
2460 implied by the other modules.
2462 2005-07-06 Akim Demaille <akim@epita.fr>
2464 Bind examples/calc++ to the package.
2465 * examples/calc++/Makefile: Remove, replaced by...
2466 * examples/calc++/Makefile.am: ... this new file.
2467 * examples/calc++/test: Remove input.
2468 * examples/calc++/compile: Remove.
2469 * examples/Makefile.am: New.
2470 * configure.ac, Makefile.am: Adjust.
2471 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
2473 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
2475 * data/glr.c (yyFail): Drastically simplify; since the format argument
2476 never had any % directives, we can simply pass it to yyerror.
2477 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
2478 be modified later, as that is the usual style in glr.c.
2479 Problems reported by Paul Hilfinger.
2481 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
2482 and size overflow errors.
2483 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
2484 in case the user prolog sets feature-test macros like _GNU_SOURCE.
2485 (YYSIZEMAX): New macro.
2486 (yystpcpy): New function, taken from yacc.c.
2487 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
2488 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
2489 so that we don't have to maintain their signatures.
2490 (yyFail): Check for buffer overflow, by using vsnprintf rather
2491 than vsprintf. Allocate a bigger buffer if possible.
2492 Report an error if buffer allocation fails.
2493 (yyStackOverflow): New function.
2494 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
2495 the initialization was successful. It might fail if storage was
2497 (yyexpandGLRStack): Add more checks for storage allocation failure.
2498 Use yyStackOverflow to report failures.
2499 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
2500 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
2501 Don't assume stack number fits in int.
2502 (yysplitStack): Check for storage allocation failure.
2503 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
2504 can print diagnostics on storage allocation failure. All callers
2506 (yyresolveValue): Use yybool for boolean.
2507 (yyreportSyntaxError): Check for size-calculation overflow.
2508 This code is taken from yacc.c.
2509 (yyparse): Check for storage allocation errors when allocating
2512 2005-07-05 Akim Demaille <akim@epita.fr>
2514 Extract calc++ from the documentation.
2515 * doc/bison.texinfo (Calc++): Add the extraction marks.
2516 * examples/extexi: New, from the aborted GNU Programming 2E.
2517 Separate the different paragraph of a file with empty lines.
2518 * examples/Makefile: Use it to extract the whole calc++ example.
2520 2005-06-24 Akim Demaille <akim@epita.fr>
2522 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
2525 2005-06-22 Akim Demaille <akim@epita.fr>
2527 * doc/bison.texinfo (C++ Language Interface): First stab.
2528 (C++ Parsers): Remove.
2530 2005-06-22 Akim Demaille <akim@epita.fr>
2532 * data/lalr1.cc (yylex_): Honor %lex-param.
2534 2005-06-22 Akim Demaille <akim@epita.fr>
2536 Start a set of simple examples.
2537 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
2538 * examples/calc++/calc++-driver.hh,
2539 * examples/calc++/calc++-parser.yy,
2540 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
2541 * examples/calc++/compile, examples/calc++/test: New.
2543 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
2545 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2546 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2547 which stems from the 2005-05-27 patch.
2549 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2551 * data/glr.c: Modify treatment of unused parameters to permit use
2552 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2554 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2556 Fix infringement on user name space reported by Janos Zoltan Szabo.
2557 * data/yacc.c (yyparse): strlen -> yystrlen.
2559 2005-05-30 Akim Demaille <akim@epita.fr>
2561 * data/lalr1.cc (_): New.
2562 Translate the various messages.
2564 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2566 Fix infringement on user name space reported by Bruno Haible.
2567 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2568 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2569 the user's name space.
2570 (alloca): Include <stdlib.h> to get it, if it's not built in.
2571 (YYMALLOC, YYFREE): Define only if needed.
2572 (malloc, free): Declare, but only if needed, as this infringes on
2573 the user name space.
2575 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2577 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
2578 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
2580 * lib/ebitset.c (min, max): Undef before defining.
2581 * lib/vbitset.c (min, max): Likewise.
2582 * lib/subpipe.c (create_subpipe): Save local variables in case
2583 vfork clobbers them.
2585 2005-05-24 Bruno Haible <bruno@clisp.org>
2587 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
2588 error message syntax used by gcc-4.0.
2590 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
2592 * README: Mention m4 1.4.3. Remove obsolete advice about
2593 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
2595 * bootstrap: Remove workaround for problem I encountered with
2596 gettext 0.14.1; it seems to be fixed now.
2598 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
2600 * NEWS: Version 2.0a.
2602 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2603 the previous change.
2605 Various maintainer cleanups.
2606 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2607 conftest*, for benefit of CVS commands run at the same time as
2608 "configure". Add build-aux, since "bootstrap" now creates it and
2610 * Makefile.cfg (move_if_change): Remove.
2611 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2612 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

2617 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
2619 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
2620 this is now the recommended name.
2621 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2622 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2623 ylwrap. These files now go into build-aux.
2624 * config/move-if-change: Remove.
2625 * config/prev-version.txt: Bump from 1.75 to 2.0.
2627 * bootstrap: Add stdio-safer, unistd-safer modules.
2628 Remove m4/glibc2.m4 (introduced by latest gnulib, but
2630 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
2631 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2632 * lib/subpipe.c: Include "unistd-safer.h".
2633 (create_subpipe): Make sure all the newly-created
2634 file descriptors are > 2, so that diagnostics don't
2635 get sent down them (which might cause Bison to hang, in theory).
2636 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2637 * src/files.c (xfopen): Use fopen_safer, not fopen.
2639 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2640 yesterday's yacc.c fix.
2642 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
2644 * data/glr.c, data/lalr1.cc: Update copyright date.
2646 Fix a destructor bug reported by Wolfgang Spraul in
2647 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
2648 * data/yacc.c (yyabortlab): Don't call destructor, and
2649 don't set yychar to EMPTY.
2650 (yyoverflowlab): Don't call destructor.
2651 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2652 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2653 since we no longer output the message "discarding lookahead token
2656 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2658 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2659 fix a small glitch in debugging output.
2660 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2661 after YY_SYMBOL_PRINT where needed.
2663 (struct yyGLRState): Add some comments.
2664 (struct yySemanticOption): Add some comments.
2665 (union yyGLRStackItem): Add comment.
2667 (yymergeOptionSets): Correct this to properly perform the union,
2668 avoiding infinite reported by Michael Rosien.

2712 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
2714 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
2715 Problem reported by Ralf Menzel.
2717 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2719 * tests/actions.at: Test that stack overflow invokes destructors.
2720 From Marcus Holland-Moritz.
2721 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2723 (yyreturn): to here. That way, destructors are called properly
2724 even if the stack overflows, or the user calls YYACCEPT or
2725 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2726 (yyoverflowlab): Destroy the lookahead.
2728 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2730 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2732 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2734 * NEWS: Bison-generated C parsers no longer quote literal strings
2735 associated with tokens.
2736 * src/output.c (prepare_symbols): Don't escape strings,
2737 since users don't want to see C escapes.
2738 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2740 * tests/input.at (Torturing the Scanner): Likewise.
2741 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2743 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2745 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2746 the data size is known to be too small and we can't increase it.
2747 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2749 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2751 * src/parse-gram.y: Include quotearg.h.
2752 (string_as_id): Quote $1 before using it as a key, since the
2753 lexer no longer quotes it for us.
2754 (string_content): Don't strip quotes, since lexer no longer
2756 * src/scan-gram.l: Include quotearg.h.
2758 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2759 a key, since the rest of the lexer doesn't quote it.
2760 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2761 * tests/regression.at (Token definitions): Check for backslashes
2764 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2765 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2766 (yyparse): Revamp code to generate long syntax error message, to
2767 make it easier to translate, and to avoid problems with arithmetic
2768 overflow. Change "virtual memory" to "memory" in diagnostic, since
2769 we don't know whether the memory is virtual.
2771 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2773 * NEWS: Bison-generated C parsers now use the _ macro to
2775 * data/yacc.c (_) [!defined _]: New macro.
2776 All English strings wrapped inside this macro.
2777 * doc/bison.texinfo (Bison Parser): Document _.
2778 * po/POTFILES.in: Include src/parse-gram.c, since it now
2779 includes translateable strings that parse-gram.y doesn't.
2781 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2783 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2784 reverting the 2004-10-11 change to this function.
2785 (symbol_check_alias_consistency): Don't call symbol_type_set
2786 if the type name is already correct.
2787 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2789 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2791 * tests/regression.at (Token definitions): Don't use a token named
2792 c, as that generates a "#define c ..." that runs afoul of buggy
2793 stdlib.h that uses the identifier c as a member of struct
2794 drand48_data. Problem reported by Horst Wente.
2796 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2798 * bootstrap: Change translation URL from
2799 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2800 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2801 redirection glitches. Problem reported by twlevo@xs4all.nl.
2803 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2805 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2806 after operands; POSIX says this isn't portable for the c99 command.
2808 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2810 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2811 immediately if a data overrun has occurred; this may help us track
2812 down what may be a spurious failure on MacOS.
2814 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2816 Respond to problems reported by twlevo@xs4all.nl.
2818 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
2820 * src/vcg.h: Comment fix.
2821 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2822 (G_CMAX): Change to -1 instead of INT_MAX.
2824 * data/yacc.c (yyparse): Omit spaces before #line.
2826 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2828 * src/tables.c (state_number_to_vector_number): Put it inside an
2829 "#if 0", since it's not currently used. Problem reported by
2832 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2834 * src/output.c (escaped_output): Renamed from
2835 escaped_file_name_output, since we now use it for symbol tags as
2836 well. All uses changed.
2837 (symbol_destructors_output, symbol_printers_output):
2838 Escape symbol tags too.
2839 Problem reported by Matyas Forstner in
2840 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2842 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2844 * src/output.c (user_actions_output, token_definitions_output,
2845 symbol_destructors_output, symbol_printers_output): Likewise.
2846 * src/reader.c (prologue_augment): Likewise.
2847 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2849 * src/vcg.c (output_edge): Don't quote linestyle arg.
2850 Problem reported by twlevo@xs4all.nl.
2852 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2854 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2855 example, reported by Derek M Jones. Also, make the example even
2856 more outrageous, to better illustrate how bad the problem is.
2858 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2860 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2861 putsym. Typo reported by Sebastian Piping.
2863 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2865 * doc/bison.texinfo (Language and Grammar): some -> same
2866 (Epilogue): int he -> in the
2867 Typos reported by Sebastian Piping via Justin Pence.
2869 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2871 * tests/glr-regression.at (Improper handling of embedded actions
2872 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2873 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2874 with dollar signs in test names.
2875 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2876 for a similar reason.
2878 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2880 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2881 wants to redefine G_VIEW.
2883 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
2885 * src/vcg.c (get_view_str): Remove case for normal_view.
2886 Problem reported by twlevo@xs4all.nl.
2888 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
2890 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
2891 Problem reported by twlevo@xs4all.nl.
2893 * doc/bison.texinfo: Change @dircategory from "GNU programming
2894 tools" to "Software development". Requested by Richard Stallman
2897 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
2899 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
2900 Problem reported by twlevo@xs4all.nl.
2902 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2904 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2905 keyword; it's not needed with modern compilers, and it doesn't
2906 affect correctness with older compilers. Suggested by
2909 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2911 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2912 gcc -Wswitch-default.
2913 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2914 * data/yacc.c (yyparse): Likewise.
2916 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2918 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2919 already. Let config.h define any nonstandard values.
2921 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2923 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2924 for the benefit of slower hosts. Problem reported by
2927 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2929 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2930 being defined and not used.
2931 * data/lalr1.cc (yyparse): Likewise.
2932 Use "if (false)" rather than "if (0)".
2934 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2936 * TODO: Mention that we should allow NUL bytes in tokens.
2938 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
2940 * src/scan-skel.l (<<EOF>>): Don't close standard output.
2941 Problem reported by Hans Aberg.
2943 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
2945 * src/getargs.c (version): Happy new year; update overall
2946 program copyright date from 2004 to 2005.
2948 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2949 Problem reported by Hans Aberg.
2950 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2951 (Output file names.): Add a test for the case when standard output
2954 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2956 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2957 to fix an oversight in the Bison 2.0 manual.
2959 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2961 * NEWS: Version 2.0. Reformat the existing news items since
2962 1.875, so that related items are grouped together.
2963 * configure.ac (AC_INIT): Bump version to 2.0.
2964 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2966 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2967 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2968 otherwise, we're not testing alloca. Unfortunately there's no
2969 simple way to consult HAVE_ALLOCA here.
2971 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2974 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2975 hand. This avoids a warning about comparing int to size_t when
2976 GCC warnings are enabled.
2978 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2980 * NEWS: Bison-generated parsers no longer default to using the
2981 alloca function (when available) to extend the parser stack, due
2982 to widespread problems in unchecked stack-overflow detection.
2983 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2984 responsibility to set it to a positive value. This lets the user
2985 specify a value that is not a preprocessor constant.
2986 * data/yacc.c (YYMAXDEPTH): Likewise.
2987 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2988 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2989 to be a compile-time constant. However, explain the constraints on it.
2990 Also, explain the constraints on YYINITDEPTH.
2991 (Table of Symbols): Explain that alloca is no longer the default.
2992 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2995 * doc/bison.texinfo (Location Default Action): Mention that n must
2996 be zero when k is zero. Suggested by Frank Heckenbach.
2998 2004-12-22 Akim Demaille <akim@epita.fr>
3000 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
3001 (parser::state_type, parser::semantic_type, parser::location_type):
3002 Private, not public.
3003 (parser::parse): Return ints, not bool.
3004 Returning a bool introduces a problem: 0 corresponds to false, and
3005 it seems weird to return false on success. Returning true changes
3006 the conventions for yyparse.
3007 Alternatively we could return void and send an exception.
3008 There is no clear consensus (yet?).
3009 (state_stack, semantic_stack, location_stack): Rename as...
3010 (state_stack_type, semantic_stack_type, location_stack_type): these.
3011 Private, not public.
3012 * tests/c++.at: New.
3013 * tests/testsuite.at, tests/Makefile.am: Adjust.
3015 2004-12-21 Akim Demaille <akim@epita.fr>
3017 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
3019 2004-12-21 Akim Demaille <akim@epita.fr>
3021 Don't impose std::string for filenames.
3023 * data/lalr1.cc (b4_filename_type): New.
3024 (position::filename): Use it.
3025 (parser.hh): Move the inclusion of stack.hh and location.hh below
3026 the user code, so that needed headers for the filename type can be
3028 Forward declare them before the user code.
3029 * tests/Makefile.am (check-local, installcheck-local): Pass
3030 TESTSUITEFLAGS to the TESTSUITE.
3032 2004-12-20 Akim Demaille <akim@epita.fr>
3034 Use more STL like names: my_class instead of MyClass.
3036 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
3037 (SemanticStack, SemanticType, StateStack, StateType)
3038 (TokenNumberType, Stack, Slice, Traits, Parser::location)
3039 (Parser::value): Rename as...
3040 (location_stack, location_type, rhs_number_type, semantic_stack)
3041 (semantic_type, state_stack, state_type, token_number_type, stack)
3042 (slice, traits, parser::yylloc, parser::yylval): these.
3044 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
3046 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
3048 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
3049 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
3051 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
3053 Remove uses of 'short int' and 'unsigned short int'. This raises
3054 some arbitrary limits. It uses more memory but nowadays that's
3055 not much of an issue.
3057 This change does not affect the generated parsers; that's a different
3058 task, as some users will want to conserve memory there.
3060 Ideally we should use size_t to represent all object counts, and
3061 something like ptrdiff_t to represent signed differences of object
3062 counts; but that will require more code-cleanup than I have the
3063 time to do right now.
3065 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
3066 Use size_t, not int or short int, to count objects.
3067 * src/closure.c (nritemset, closure): Likewise.
3068 * src/closure.h (nritemset, closure): Likewise.
3069 * src/nullable.c (nullable_compute): Likewise.
3070 * src/print.c (print_core): Likewise.
3071 * src/print_graph.c (print_core): Likewise.

3074 * src/tables.c (default_goto, goto_actions): Likewise.
3076 * src/gram.h (rule_number, rule): Use int, not short int.
3077 * src/output.c (prepare_rules): Likewise.
3078 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
3079 errs, reductions): Likewise.
3080 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
3082 * src/tables.c (vector_number, tally, action_number,
3083 ACTION_NUMBER_MINIMUM): Likewise.
3084 * src/output.c (muscle_insert_short_int_table): Remove.
3086 2004-12-17 Akim Demaille <akim@epita.fr>
3088 * data/lalr1.cc: Extensive Doxygenation.
3089 (error_): Rename as...
3090 (error): this, since it is visible to the user.
3092 (Parser::message): Now an automatic variable from...
3093 (Parser::yyreport_syntax_error_): here.
3094 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
3096 * tests/input.at: Escape $.
3098 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
3100 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
3101 Parenthesize rhs to avoid obscure problems with mistakes like
3102 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
3103 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
3104 b4_rhs_location): Likewise.
3105 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
3106 b4_rhs_location): Likewise.
3108 2004-12-16 Akim Demaille <akim@epita.fr>
3110 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
3111 yacc.c: be sure to stay within yycheck_.
3112 * tests/actions.at: Re-enable C++ tests.
3114 2004-12-16 Akim Demaille <akim@epita.fr>
3116 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
3119 2004-12-16 Akim Demaille <akim@epita.fr>
3121 Use #define to handle the %name-prefix.
3123 * data/glr.c, data/yacc.c: Comment changes.
3124 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
3125 so that one can refer to yylex in the parser file, and have it
3126 renamed, as is the case with other skeletons.
3128 2004-12-16 Akim Demaille <akim@epita.fr>
3130 Move lalr1.cc internals into yy*.

3150 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
3152 Fix some problems reported by twlevo at xs4all.
3153 * src/symtab.c (symbol_new): Report an error if the input grammar
3154 contains too many symbols. This is better than calling abort() later.
3155 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
3156 (struct node, struct graph):
3157 Rename member expand to stretch. All uses changed.
3158 (struct graph): Remove member layoutalgorithm. All uses removed.

3164 2004-12-15 Akim Demaille <akim@epita.fr>
3166 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
3167 Add more Doxygen comments.
3168 (symprint_, stack_print_, reduce_print_, destruct_, pop)
3169 (report_syntax_error_, translate_): Rename as...
3170 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
3171 (yypop_, yyreport_syntax_error_, yytranslate_): this.
3173 2004-12-15 Akim Demaille <akim@epita.fr>
3175 * data/lalr1.cc (lex_): Rename as...
3177 Move the trace here.
3178 Take the %name-prefix into account.
3179 Reported by Alexandre Duret-Lutz.
3181 2004-12-15 Akim Demaille <akim@epita.fr>
3183 Simplify the C++ parser constructor.
3185 * data/lalr1.cc (debug_): Rename as...
3186 (yydebug_): so that the parser's internals are always in the yy*
3189 (b4_parse_param_decl): Remove the leading comma as it is now only
3190 called as unique argument list.
3191 (Parser::Parser): Remove the constructor accepting a location and
3192 an initial debugging level.
3193 Remove from the other ctor the argument for the debugging level.
3194 (debug_level_type, debug_level, set_debug_level): New.
3196 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
3199 2004-12-15 Akim Demaille <akim@epita.fr>
3201 Remove b4_root related material: failure experiment
3202 (which goal was to allow to derive from a class).
3204 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
3205 definitions and uses.
3207 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
3209 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
3210 not 2, since it's not portable to subtract 1 from the start of an
3211 array. The new item 0 is never set or used. All uses changed.
3213 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
3214 the default definition of YYLLOC_DEFAULT. Problem reported
3215 by Frank Heckenbach.
3217 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
3219 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
3220 the normal case and one for the error case. Just use the
3221 first one uniformly. Problem reported by Frank Heckenbach.
3222 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
3223 use exactly the same macro in both places.
3224 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
3225 so that the normal-case YYRHSLOC works for the error case too.
3227 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
3228 (YYLLOC_DEFAULT): Use the same macro as glr.c.
3229 * doc/bison.texinfo (Location Default Action): Don't claim that
3230 we have an array of locations. Use the same macro for both glr
3231 and lalr parsers. Mention YYRHSLOC. Mention what happens when
3234 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
3236 * HACKING: Update email addresses to send announcements to.
3238 * configure.ac (AC_INIT): Bump version to 1.875f.
3240 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
3242 * NEWS: Version 1.875e.
3243 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
3245 * src/scan-skel.l: Include "complain.h", for "fatal".
3247 * src/relation.h (relation_print, relation_digraph):
3248 Relation sizes are of type relation_node, not size_t (this is
3249 merely a doc fix, since the two types are equivalent).
3250 (relation_transpose): Relation sizes are of type relation_node,
3252 * src/relation.c: Likewise.
3253 (top, infinity): Now of type relation_node, not int.
3254 (traverse, relation_transpose): Use relation_node, not int.
3256 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
3257 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
3258 (yyparse): Remove unused local introduced in 2004-10-25 patch.
3260 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
3261 specifying whether the test should be skipped. Use it tp
3262 specify that the [%defines %skeleton "lalr1.cc"] tests currently
3263 fail on some hosts, and should be skipped.
3265 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3267 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
3268 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
3269 unless otherwise specified below.
3271 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
3272 to allocate kernel_base, kernel_items, kernel_size, since
3273 they needn't be initialized to 0.
3274 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
3275 * src/closure.c (new_closure): Likewise, for itemset.
3276 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

3291 (goto_actions): Likewise for state_count.
3292 (pack_table): Likewise for base, pos, check.
3293 (tables_generate): Likewise for width.
3295 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
3296 for initial core. Just have a separate core, so we needn't worry
3297 about whether kernel_size and kernel_base are initialized.
3299 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
3300 kernel_size, kernel_items): Remove unnecessary initialization.

3305 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
3306 conflrow, conflict_table, conflict_list, table, check):
3309 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
3310 This is because all callers pass unsigned int.
3311 * src/closure.h (new_closure): Likewise.
3313 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
3314 (build_relations): Initialize includes[i] in all cases.

3319 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
3321 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
3322 conflict_list[0] was always 0, but now it isn't initialized.
3324 * src/table.c (table_grow): When conflict_table grew, the grown
3325 area wasn't cleared. Fix this.
3327 * lib/.cvsignore: Add strdup.c, strdup.h.
3328 * m4/.cvsignore: Add strdup.m4.
3330 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
3332 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
3333 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
3334 GOTO_NUMBER_MAXIMUM, since we occasionally compute
3335 ngotos + 1 without checking for overflow.
3336 (build_relations): Use END_NODE, not -1, to denote end of edges.
3337 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
3338 build_relations): Use goto_number, not int, for goto numbers.
3339 * src/tables.c (save_column, default_goto): Likewise.
3341 2004-11-23 Akim Demaille <akim@epita.fr>
3343 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
3344 of #defining from yystype.
3345 Don't typedef yystype, C++ does not need it.
3346 This lets it possible to forward declare it as union.
3348 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
3350 * bootstrap (gnulib_modules): Add extensions.
3351 Problem reported by Jim Meyering.
3353 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
3355 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
3356 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
3357 src/system.h, src/tables.c: XFREE -> free, to accommodate
3358 recent change to gnulib xalloc.h.
3359 Problem reported by Jim Meyering.
3361 2004-11-17 Akim Demaille <akim@epita.fr>
3363 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
3365 2004-10-28 Akim Demaille <akim@epita.fr>,
3366 Alexandre Duret-Lutz <adl@gnu.org>
3368 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
3371 Use it instead of cdebug_.
3372 (Parser::debug_stream, Parser::set_debug_stream): New.
3373 (Parser::symprint_): Define cdebug_ for temporary backward
3375 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
3378 2004-11-17 Akim Demaille <akim@epita.fr>
3380 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
3381 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
3382 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
3383 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
3385 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
3387 * data/glr.c (yyloc_default): Remove; not used.
3388 Problem reported by Frank Heckenbach.
3390 2004-10-25 Akim Demaille <akim@epita.fr>
3392 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
3393 Introduce another definition to address simple location arrays.
3394 (yyGLRStack): New member: yyerror_range.
3395 (yyrecoverSyntaxError, yyparse): Update it.
3396 (yyrecoverSyntaxError): Use it when shifting the error token to
3397 have an accurate range, equivalent to the one computed by both
3398 yacc.c and lalr1.cc.
3399 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
3400 that column numbers start at column 0, as per GNU Coding
3401 Standards, the others tests, and the doc.
3402 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
3403 Adjust to the above change (first column is 0).
3404 And adjust the location of the "<error>", now covering the whole
3407 2004-10-22 Akim Demaille <akim@epita.fr>
3408 and Paul Eggert <eggert@cs.ucla.edu>
3410 Remove some arbitrary limits on goto numbers and relations.
3411 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
3412 initial values, since they're never used.
3413 (set_goto_map): ngotos is now unsigned, so test for overflow
3414 by seeing whether it wraps around to zero.
3415 * src/lalr.h (goto_number): Now size_t, not short int.
3416 (GOTO_NUMBER_MAXIMUM): Remove.
3417 * src/relation.c (relation_print, traverse, relation_transpose):
3418 Check for END_NODE rather than looking at sign.
3419 * src/relation.h (END_NODE): New macro.
3420 (relation_node): Now size_t, not short int.
3422 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
3424 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
3425 keyword, not an identifier. Problem reported by Baron Schwartz in
3426 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
3428 2004-10-11 Akim Demaille <akim@epita.fr>
3430 * src/symtab.c (symbol_check_alias_consistency): Also check
3431 type names, destructors, and printers.
3432 Reported by Alexandre Duret-Lutz.
3433 Recode the handling of associativity and precedence in terms
3434 of symbol_precedence_set.
3435 Accept no redeclaration at all, not even equal to the previous
3437 (redeclaration): New.
3438 Use it to factor redeclaration complaints.
3439 (symbol_make_alias): Don't set the type of the alias, let
3440 symbol_check_alias_consistency do it as for other features.
3441 * src/symtab.h (symbol): Add new member prec_location, and
3443 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
3444 * tests/input.at (Incompatible Aliases): New.
3446 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
3448 .cvsignore fixes to accommodate gnulib changes,
3449 and the practice of naming build directories "_build".
3450 * .cvsignore: Add "_*". Sort.
3451 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
3452 * m4/.cvsignore: Add "*_gl.m4".
3454 2004-10-06 Akim Demaille <akim@epita.fr>
3456 * src/parse-gram.y (add_param): Fix the truncation of trailing
3459 2004-10-05 Akim Demaille <akim@epita.fr>
3461 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3462 whether the reducion was empty or not. This leaves room to
3463 improve the use of YYLLOC_DEFAULT in such a case.
3464 lalr1.cc is still experimental, so changing this is acceptable.
3465 And finally, there are probably not many users who changed the
3466 handling of locations in GLR, so changing is admissible too.
3468 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3469 empty reduction, set @$ to an empty location ending the previously
3471 Adjust uses to make sure the code is triggered on empty
3473 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
3474 expected output: empty reductions have empty locations.
3476 2004-09-29 Akim Demaille <akim@epita.fr>
3478 * data/lalr1.cc: Move towards a more standard C++ coding style
3479 for templates: Class < T > -> Class<T>.
3481 2004-09-29 Akim Demaille <akim@epita.fr>
3483 * data/lalr1.cc: Reinstall the former ctor, for sake of
3484 compatibility, but warn it will be removed.
3485 Move towards a more standard C++ coding style (i.e., type *var ->
3488 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
3490 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
3491 since it's less likely to work if NULs are involved in the future.
3493 2004-09-27 Akim Demaille <akim@epita.fr>
3495 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
3497 2004-09-27 Akim Demaille <akim@epita.fr>
3499 * data/lalr1.cc (b4_parse_param_decl_1): New.
3500 (b4_parse_param_decl): Use it to have different names between attribute
3502 (b4_cc_constructor_call): Likewise.
3504 2004-09-24 Akim Demaille <akim@epita.fr>
3506 * src/parse-gram.y (add_param): Strip the leading and trailing
3507 blanks from a formal argument declaration.
3508 (YY_LOCATION_PRINT): New.
3510 2004-09-24 Akim Demaille <akim@epita.fr>
3512 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
3515 2004-09-24 Akim Demaille <akim@epita.fr>
3517 * doc/bison.texinfo (Table of Symbols): Sort.
3519 2004-09-21 Akim Demaille <akim@epita.fr>
3521 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
3522 the useless parentheses.
3523 Suggested by Paul Eggert.
3525 2004-09-20 Akim Demaille <akim@epita.fr>
3527 Let the initial-action act on the look-ahead, and use it for the
3528 "initial push" (corresponding to an hypothetical beginning-of-file).
3529 And let lalr1.cc honor %initial-action.
3531 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
3533 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3534 (Parser::Parser): Remove the ctor that used to initialize it.
3535 (Parser::parse): Like in the other skeletons, issue the "starting
3536 parse" message before any action.
3537 Honor %initial-action.
3538 Initialize the stacks with the lookahead.
3539 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3541 Push them in the stacks.
3542 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3544 2004-09-20 Akim Demaille <akim@epita.fr>
3546 * doc/bison.texinfo (Initial Action Decl): New.
3548 2004-09-20 Akim Demaille <akim@epita.fr>
3550 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3551 clearer criterion to define it.
3552 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3553 When reducing on an empty RHS, use the latest stacked location as
3555 yylloc is not always available.
3556 * data/glr.c: Likewise.
3557 Also, honor initial-actions.
3559 2004-09-20 Akim Demaille <akim@epita.fr>
3561 * data/yacc.c (YY_LOCATION_PRINT): New.
3562 Define when we know YYLTYPE's structure, i.e., when the default
3563 YYLLOC_DEFAULT is used.
3564 * data/c.m4 (b4_yysymprint_generate): Use it.
3565 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3566 value of the result.
3567 (error_start_): Replace with...
3568 (error_range_): this location array.
3569 This allows to replace code relying on the implementation of
3570 locations by portable code.
3571 * data/yacc.c (yylerrsp): Replace with...
3572 (yyerror_range): this.
3573 Every time a token is popped, update yyerror_range[0], to have an
3574 accurate location for the error token.
3575 * data/glr.c (YY_LOCATION_PRINT): New.
3576 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3577 deference a pointer.
3578 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3579 report the location in %printers.
3581 * src/scan-skel.l: Instead of abort, report error messages to ease
3582 understanding skeleton scanning failures.
3584 2004-09-16 Akim Demaille <akim@epita.fr>
3586 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3587 (iterator, const_iterator): these, to be more in the C++ spirit.
3588 Also, return reverse iterators so that when displaying the stack
3589 we display its bottom first.
3590 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3592 We should probably use vector here though.
3594 2004-09-16 Akim Demaille <akim@epita.fr>
3596 Have more complete shift traces.
3598 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3599 to report Shifts instead of ad hoc YYDPRINTF invocations,
3600 including for the error token.
3601 * data/lalr1.cc (symprint_): Output the location.
3602 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3603 output the location within the %printer.
3604 Activate GLR tests, at least to make sure they compile properly.
3605 They still don't pass though.
3606 * tests/calc.at: Adjust expect verbose output, since now "Entering
3607 state..." is on a different line than the "Shifting" message.
3609 2004-09-08 Akim Demaille <akim@epita.fr>
3611 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3612 Bison directive from the Bison file to the invocation of this
3613 macro, so that these directives are passed to
3614 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3615 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3616 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3617 the extra Bison directives instead of the whole series.
3618 Change the grammar so that there are recoverable errors, and
3619 unrecoverable errors. Now we can have the parser give up before
3620 consuming the whole input. As a result we now can observe that
3621 the lookahead is freed when needed.
3622 Change the parser source to parse argv[1] instead of a hard coded
3624 Simplify yylex, and give a value and location to EOF.
3625 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3626 passed directives already coded in the file.
3627 Add some tests to check the location of "error".
3628 For some tests, the C++ parser is correct, and not yacc.c.
3629 For other tests, they provide different, but unsatisfying, values,
3630 so keep the C++ value so that at least one parser is "correct"
3631 according to the test suite.
3632 (Actions after errors): Remove, this is subsumed by the
3633 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3635 2004-09-06 Akim Demaille <akim@epita.fr>
3637 * data/lalr1.cc: Adjust the indentation of the labels.
3641 2004-09-06 Akim Demaille <akim@epita.fr>
3643 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3644 argument, an informative message.
3645 Call YY_SYMBOL_PRINT.
3646 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3647 * data/lalr1.cc (destruct_): Likewise.
3648 In addition, no longer depend on b4_yysymprint_generate and
3649 b4_yydestruct_generate to generate these functions, do it "by
3652 2004-09-03 Akim Demaille <akim@epita.fr>
3654 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3655 invoked, yydestruct the lookahead.
3656 * tests/calc.at (Calculator $1): Update the expected lengths of
3657 traces: there is an added line for the discarded lookahead.
3658 * doc/bison.texinfo (Destructor Decl): Some rewording.
3659 Define "discarded" symbols.
3661 2004-09-02 Akim Demaille <akim@epita.fr>
3663 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3665 2004-09-02 Akim Demaille <akim@epita.fr>
3667 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3668 (YYDSYMPRINTF): Rename as...
3669 (YY_SYMBOL_PRINT): this.
3670 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3672 Use it instead of direct symprint_ calls.
3673 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3676 2004-09-02 Akim Demaille <akim@epita.fr>
3678 * data/lalr1.cc (b4_yysymprint_generate): New.
3679 (symprint_): New member function, defined when YYDEBUG.
3680 Use it consistently instead of token/nterm debugging output by
3682 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
3683 %printer calls to use cdebug_ when using lalr1.cc.
3685 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
3687 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
3688 with #ifdef YYDEBUG.
3690 2004-08-26 Akim Demaille <akim@epita.fr>
3692 * doc/bison.texinfo (Implementing Loops): Rename as...
3693 (Implementing Gotos/Loops): this.
3695 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
3697 Adjust to latest gnulib.
3698 * bootstrap (gnulib_modules): Add xalloc-die.
3699 Set LC_ALL=C so that file names sort consistently.
3700 Prefer the gnulib copies of gettext.m4, glibc21.m4,
3701 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
3702 uintmax_t.m4, ulonglong.m4.
3703 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
3704 po.m4 since we are now using _gl.m4 instead.
3706 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
3708 * src/scan-action.l: Remove. Scanning of semantic actions is
3709 handled in scan-gram.l.
3711 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
3713 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
3715 * src/location.h (struct): The file member is a uniqstr.
3716 (equal_boundaries): Use UNIQSTR_EQ for comparison.
3718 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
3720 Fix bug with non-%union parsers that have printers or destructors,
3721 which led to a Bison core dump. Reported by Peter Fales in
3722 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
3724 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
3725 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
3726 not to our own type.
3727 * src/output.c (symbol_destructors_output, symbol_printers_output):
3728 Don't assume %union.
3729 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
3730 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
3731 UNION-FLAG. All callers changed.
3732 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3733 Use type char, not unsigned int, when declaring an array of char;
3734 this lets us remove a cast.
3735 (Printers and Destructors): Add non-%union test cases.
3737 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3739 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3740 GLR writeups. E.g., avoid frenchspacing and the future tense,
3741 change "lookahead" to "look-ahead", and change "wrt" to "with
3744 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3746 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
3747 New sections, split off from the GLR Parsers section. Put the new
3748 Simple GLR Parser near the start of the GLR section, for clarity.
3749 Rewrite connective text.
3751 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
3753 * doc/bison.texinfo (Simple GLR Parsers): New section.
3755 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3757 * NEWS, TODO, doc/bison.texinfo:
3758 Use "look-ahead" instead of "lookahead", to be consistent.

3782 * README: Update location of patched M4 distribution.
3784 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
3786 Don't assume the C++ compiler takes the same arguments as the C compiler
3788 * configure.ac (O0CXXFLAGS): New var.
3789 * tests/atlocal.in (CXXFLAGS): Use it.
3791 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
3793 Fix some "make check" problems with C++ reported by
3794 Albert Chin-A-Young for Tru64 C++ in this thread:
3795 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
3797 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
3798 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3799 Output to a .cc file for C++, not to a .c file.

3807 C++ compiler. (trivial change)
3809 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
3811 Spent a few hours checking out which prerequisite versions the
3812 current sources actually require. I went all the way back to
3813 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3814 a seemingly endless set of combinations of versions more recent
3815 than that. The bottom line is that the current sources require
3816 fairly recent versions of the build tools, and it'll be some work
3818 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3819 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3820 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3821 Add comments explaining why those particular versions are
3824 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
3825 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3826 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3828 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
3829 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
3831 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3833 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
3834 0.11.5. Suggested by Bruno Haible.
3835 * bootstrap: Remove gettext version checking.
3837 * doc/bison.texinfo (Decl Summary): Also mention that %union
3838 can depend on prerequisite types. Problem reported by Tim
3841 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3843 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3844 * README-alpha: Don't tell people not to package this.
3846 * bootstrap: Don't assume $(...) works; use `...` instead.
3847 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3850 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3851 put into the -d output file, and mention what to do if YYSTYPE is
3854 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3856 Undo change made earlier today: it caused autopoint to not bring
3857 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3860 * bootstrap: Check that gettext version matches what's in
3861 configure.ac. Warn users to ignore robots.txt ERROR 404.
3862 * bootstrap: Undo today's earlier change (logged below).
3863 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3865 The gettext version checking is causing more trouble than it's
3866 curing; remove it. Problem reported by Paul Hilfinger.
3868 * bootstrap: Issue a warning that one can expect a message
3869 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3870 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3872 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3874 Ensure that the C++ compiler used for testing actually works on a
3875 simple test program; if not, skip the C++-related tests. Problem
3876 reported by Vin Shelton in:
3877 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
3879 * m4/cxx.m4: New file.

3886 * data/glr.c (yylloc): Output this macro even if locations are not
3887 being generated, as the GLR parser needs it even in that case.
3888 Problem reported by Troy A. Johnson
3889 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
3891 * configure.ac (AC_INIT): Update to 1.875e.

3899 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
3900 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3901 lalr1.cc runs afoul of the first, and the last two are no longer
3902 supported by GCC 3.4.0.
3903 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3904 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
3906 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
3908 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
3909 unsigned int, for compatibility with latest gnulib hash module.

3930 Fix typo by replacing $1 with $option.
3931 Remove more 'intl'-related files.
3932 Don't DEFUN AM_INTL_SUBDIR twice.
3934 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,

3940 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
3941 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
3942 * src/.cvsignore: Add *.output.
3944 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3945 gets copied to the output file.
3947 2004-04-28 Paul Eggert <eggert@twinsun.com>
3949 Get files from the gnulib and po repositories, instead of relying
3950 on them being in our CVS. Upgrade to latest versions of gnulib
3953 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3954 * bootstrap: Bootstrap from gnulib and po repositories.
3955 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3956 * README-cvs: Document these changes. Remove version numbers from
3957 mentions of build tools, since they change so often. Mention Flex.

3961 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
3962 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3964 (AC_ISC_POSIX): Remove; we no longer support this
3965 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3966 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3967 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3968 Do not check for C89 headers, except for locale.h which is used
3969 by the Yacc library and must port to K&R hosts.
3970 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
3971 Do not check for C89 functions, except for setlocale which is
3972 used by the Yacc library.

3983 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3984 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
3985 Define to empty, as gnulib.mk will do the rest for us.
3986 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
3988 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
3989 (lib_SOURCES): New symbol, containing only the non-gnulib libs.

4020 Remove, as these files are now generated automatically
4021 by bootstrap or automake.

4051 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
4052 case, as stos_ is now used by destructors due to the 2004-02-09
4055 Remove more K&R C support.

4077 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
4079 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
4080 so that this include file can stand alone.
4081 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
4082 does this now. Include subpipe.h first after config.h, to
4083 test whether it can stand alone.
4085 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
4086 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
4089 * tests/synclines.at (%union synch line): Put a dummy member in
4090 the union, because empty unions aren't allowed in C. Caught
4093 2004-04-13 Jim Meyering <jim@meyering.net>
4095 * src/conflicts.c (conflicts_print): Correct format string typo:

4169 * src/scan-gram.l (scan_integer): New function.
4171 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
4172 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
4173 handle_action_dollar, handle_action_at, convert_ucn_to_byte):

4195 error_start_ when erroneous token are discarded.
4196 (Parser::parse) <yyerrlab1>: Compute the location of the error
4197 token so that it covers all the discarded tokens.
4198 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
4199 it can be called with `%skeleton "lalr1.cc"', and do that.
4201 2004-02-02 Paul Eggert <eggert@twinsun.com>
4203 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
4204 $(top_srcdir)/lib and ../lib. This fixes a bug reported
4205 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
4206 There's no need to mention top_builddir since Automake does that
4208 (INCLUDES): Remove, as Automake says it's obsolescent.
4209 Contents migrated into AM_CPPFLAGS as described above.
4210 * lib/Makefile.am (INCLUDES): Remove; obsolescent.

4218 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4220 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
4221 resulting parsers are compilable with C++.
4223 2003-12-23 Paul Eggert <eggert@twinsun.com>
4225 * config/depcomp, config/install-sh: Sync with Automake 1.8.
4226 * src/output.c (output_skeleton): Rename local var.
4227 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
4228 Bison tokens, as this runs afoul of the 2003-10-07 change that
4229 disallowed NUL bytes in character constants or string literals.
4231 * tests/local.at: Require Autoconf 2.59's Autotest.
4232 * tests/testsuite.at: Don't include local.at, since we now assume
4233 Autoconf 2.59 or later. Autoconf 2.59 had some problems with

4333 When reducing initial empty rules, Bison parser read an initial
4334 location that is not defined. This results in garbage, and that
4335 affects Bison's own parser. Therefore we need (i) to extend Bison
4336 to support a means to initialize this location, and (ii) to use
4337 this CVS Bison to fix CVS Bison's parser.
4339 * src/reader.h, reader.c (epilogue_augment): Remove, replace

4376 error recovery loops. This patch is based on
4377 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
4378 Also, augment the similarity between lalr1.cc and yacc.c.
4379 Note: the locations of error recovery rules are not correct yet.
4381 * data/lalr1.cc: Comment changes to augment the similarity between
4382 lalr1.cc and yacc.c.
4383 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
4384 (yyerrlab1): Remove, but where it used to be (now the bottom part of
4385 yyerrlab), when hitting EOF, pop the whole stack here instead of
4386 merely falling thru the default error handling mechanism.
4387 (yyerrorlab): New label, with the old contents of YYERROR,
4388 plus the following change: pop the stack of rhs corresponding
4389 to the production that invoked YYERROR. That is how Yacc
4390 behaves (required by POSIX).
4391 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
4394 2003-08-25 Akim Demaille <akim@epita.fr>
4396 Tune local.at so that people can "autom4te -l autotest calc.at -o
4397 calc" for instance, to extract a sub test suite.
4399 * tests/testsuite.at: Move the initialization, Autotest version
4400 requirement, and AT_TESTED invocation into...
4401 * tests/local.at: here.
4402 * tests/testsuite.at: Include it for compatibility with Autoconf
4404 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should

4409 Rework code slightly to avoid gcc -Wtraditional warnings.
4410 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
4411 The returned value is now stored in *YY0. All callers changed.
4412 * src/output.c (merge_output): Adjust to the above change.
4414 2003-07-26 Paul Eggert <eggert@twinsun.com>
4416 * data/glr.c (YYASSERT): New macro.
4417 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
4418 yyresolveStates, yyprocessOneStack):
4419 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
4420 Derived from a suggestion by Frank Heckenbach.
4422 2003-07-25 Paul Eggert <eggert@twinsun.com>
4424 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
4425 for portability to K&R C (after ansi2knr, presumably). See
4426 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
4427 by Frank Heckenbach, though I have omitted the structure-initialization
4428 part of his glr-knr.diff patch since I recall that the Portable
4429 C Compiler didn't require that change.

4519 `How Can I Reset @code{yyparse}', since texinfo does not allow
4520 arbitrary @ in node names.
4522 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
4523 shouldn't be needed according to the gettext 0.12.1 documentation
4524 but which seem to be needed anyway: codeset.m4 glibc21.m4
4525 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

4547 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
4548 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
4549 the tests right now.
4550 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4551 yyerror are declared before use; C99 requires this.
4553 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4555 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
4557 (yyrecoverSyntaxError): Correct the logic for setting and testing
4559 Correct comment on handling EOF.
4560 Allow states with only a default reduction, rather than failing
4561 (I can't quite reconstruct why these were not allowed before).
4563 Fixes to avoid problem that $-N rules in GLR parsers can cause
4564 buffer overruns, corrupting state.
4566 * src/output.c (prepare_rules): Output max_left_semantic_context
4568 * src/reader.h (max_left_semantic_context): New variable declaration.

4579 (YYRHSLOC): Add parentheses, and define only if locations used.
4580 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
4582 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
4583 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4585 * tests/cxx-type.at: Exercise location information; update tests
4586 to differentiate output with and without locations.
4587 Remove forward declarations of yylex and yyerror---caused errors
4588 because default YYLTYPE not yet defined.
4589 Change semantic actions to compute strings, rather than printing
4590 them directly (to test proper passing of semantics values). Change
4591 output to prefix notation and update test data and expected results.
4592 (yylex): Track locations.
4593 (stmtMerge): Return value rather than printing, and include arguments

4604 yy::Slice::operator[] (unsigned),
4605 yy::Slice::operator[] (unsigned) const):
4606 Rename local vars to avoid warnings.
4607 * tests/glr-regression.at (Improper handling of embedded actions
4608 and $-N in GLR parsers): Remove unused local variable from yylex.
4609 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4610 (void) as arg when not pure, since we now assume C89 when building
4611 Bison. Pacify GCC by using parameter.
4613 2003-06-02 Paul Eggert <eggert@twinsun.com>
4615 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4616 yy::Location::lines, yy::Location::columns): Rename arguments
4617 to avoid shadowing; this removes a warning generated by GCC 3.3.
4619 2003-06-01 Paul Eggert <eggert@twinsun.com>
4621 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4622 to g++, as GCC 3.3 complains if you do it.
4623 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4624 everything that WARNING_CFLAGS has, except omit warnings
4625 not suitable for C++.
4626 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4627 * tests/atlocal.in (CXXFLAGS): New var.
4628 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4630 Fix a GLR parser bug I reported in February; see
4631 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4632 The problem was that GLR parsers did not conform to the C standard,
4633 because actions like { $1 = $2 + $3; } expanded to expressions
4634 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4635 to a local variable. The C standard says that expressions
4636 like (var = f ()) + (var = f ()) have undefined behavior.
4637 Another problem was that GCC sometimes issues warnings that
4638 yyfill and its parameters are unused.
4640 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4642 (yyfill): New function.
4644 (yyuserAction): Change type of yynormal to bool, so that it matches
4645 the new yyfill signature. Mark it as possibly unused.
4648 Follow up on a bug I reported in February, where a Bison-generated
4649 parser can loop. Provide a test case and a fix for yacc.c. I
4650 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4651 The original bug report is in:
4652 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4654 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4655 macro's size was becoming unwieldy.
4656 (yyerrlab): Do not discard an empty lookahead symbol, as this
4657 might destroy garbage.
4658 (yyerrorlab): New label, with the old contents of YYERROR,
4659 plus the following change: pop the stack of rhs corresponding
4660 to the production that invoked YYERROR. That is how Yacc
4661 behaves, and POSIX requires this behavior.
4662 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4663 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4664 Define 'alarm' to do nothing if unistd.h is not available.
4665 Add a new rule "exp: '-' error;" to test the above change to
4666 data/yacc.c. Use 'alarm' to abort any test taking longer than
4667 10 seconds, as it's probably looping.
4668 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4669 Also, the new yacc.c generates two fewer diagnostics for an
4672 2003-05-24 Paul Eggert <eggert@twinsun.com>
4674 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4675 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4676 This fixes a problem reported by John Bowman when the Compaq/HP
4677 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4679 * data/yacc.c (union yyalloc): Likewise.
4680 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4682 Switch from 'int' to 'bool' where that makes sense.
4684 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
4685 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
4686 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
4687 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
4688 Return or accept bool, not int. All callers changed.
4689 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,

4708 lbitset_xor_cmp): Likewise.
4709 * lib/bbitset.h: Include <stdbool.h>.
4710 (struct bitset_vtable): The following members now return bool, not
4711 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
4712 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,

4745 2003-05-14 Paul Eggert <eggert@twinsun.com>
4747 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4748 semicolon after a grammar declaration, in the interest of possible
4749 future changes to the Bison input language.
4750 Do not allow a stray semicolon at the start of the grammar.
4751 (rhses.1): Allow one or more semicolons after any rule, including
4752 just before "|" as required by POSIX.
4753 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4756 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4758 %parse-param support for lalr1.cc.
4760 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4761 b4_cc_constructor_calls, b4_cc_constructor_call,
4762 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4764 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4765 parse-param arguments.
4766 (yy::b4_parser_class_name): Declare instance variables to
4767 hold parse-param arguments.
4768 * tests/calc.at: s/value/semantic_value/ because value clashes
4769 with a member of yy::b4_parser_class_name. Adjust C++ code
4770 to handle %parse-param. Enable %parse-param test in C++.
4772 2003-05-12 Paul Eggert <eggert@twinsun.com>
4774 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4775 English a bit. Fix fclose typo. Change "const char" to "char
4776 const", and use ANSI C rather than K&R for "main". Suggest
4777 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4778 and suggest yy_switch_to_buffer.
4780 2003-05-05 Paul Eggert <eggert@twinsun.com>
4782 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4783 C89. This avoids a diagnostic on compilers that define __STDC__
4784 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4785 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4787 2003-05-03 Paul Eggert <eggert@twinsun.com>
4789 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
4790 Do not overrun array bounds.
4791 This should fix a bug reported today by Olatunji Oluwabukunmi in
4792 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
4794 2003-04-29 Akim Demaille <akim@epita.fr>
4796 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4797 * src/getargs.c, src/getargs.h: here, as bool, not int.
4798 (nondeterministic_parser): New.
4799 * src/parse-gram.y, src/scan-gram.l: Support
4800 %nondeterministic-parser.
4801 * src/output.c (prepare): Use nondeterministic_parser instead
4802 of glr_parser where appropriate.
4803 * src/tables.c (conflict_row, action_row, save_row)
4804 (token_actions, token_actions, pack_vector): Ditto.
4806 2003-04-29 Akim Demaille <akim@epita.fr>
4808 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4810 2003-04-29 Akim Demaille <akim@epita.fr>
4812 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4813 with %pure-parser and %locations to exercise the patch from Yakov
4816 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4818 * data/yacc.c: (b4_lex_param): Corrected for the case where
4819 %lex-param is provided and %pure-parser isn't.
4821 2003-04-27 Paul Eggert <eggert@twinsun.com>
4823 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4824 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4825 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4826 if it is not defined.
4827 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4829 2003-04-26 Paul Eggert <eggert@twinsun.com>
4831 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4832 Declare to be of type suitable for the ninf value itself, not of
4833 type suitable for the corresponding table, since the latter might
4834 be unsigned but the ninf value might be negative. This fixes a
4835 bug reported by Alexandre Duret-Lutz in
4836 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4838 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4839 invokes it. We shouldn't invoke it twice because it will attempt
4840 to put error.o in the archive twice. This fixes a glitch reported
4841 by Martin Mokrejs in
4842 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4844 2003-04-21 Paul Eggert <eggert@twinsun.com>
4846 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4849 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4851 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4852 Fix obvious typo that results in uncompilable GLR parsers
4853 when both %pure-parser and %locations are used. (trivial change)
4855 2003-04-17 Paul Eggert <eggert@twinsun.com>
4857 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4858 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4859 Do not insert the expected token via unput, as this runs afoul
4860 of a POSIX-compatibility bug in flex 2.5.31.
4861 All uses changed to BEGIN the parent state,
4862 since we no longer insert the expected token via unput.
4863 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4864 that is no longer emitted after the above change.
4866 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4867 the first one. This change is from Paul Hilfinger, and it fixes
4868 regression reported by Werner Lemberg in
4869 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4871 (resolve_sr_conflict): Don't invoke state_errs_set
4872 unless one or more tokens have been explicitly made errors.
4873 Otherwise, the above change causes Bison to abort.
4875 * tests/existing.at (GNU pic Grammar): New test case, taken from
4878 2003-03-31 Akim Demaille <akim@epita.fr>
4880 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4882 2003-03-31 Akim Demaille <akim@epita.fr>
4884 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4887 2003-03-31 Akim Demaille <akim@epita.fr>
4889 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4890 From Paul Hilfinger.
4892 2003-03-29 Akim Demaille <akim@epita.fr>
4894 * m4/error.m4: Do not put under dynamic conditions some code which
4895 expansion is under static control.
4897 2003-03-29 Akim Demaille <akim@epita.fr>
4899 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4901 2003-03-29 Akim Demaille <akim@epita.fr>
4903 * doc/bison.texinfo (Strings are Destroyed): New.
4905 2003-03-13 Paul Eggert <eggert@twinsun.com>
4907 * .cvsignore: Add configure.lineno.
4908 * src/.cvsignore: Add yacc.
4909 * tests/.cvsignore: Add testsuite.log.
4910 * doc/fdl.texi: Sync with latest FSF version.
4912 2003-03-12 Paul Eggert <eggert@twinsun.com>
4914 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4915 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4916 cursor, instead of leaving it undefined. This fixes a bug
4917 reported by Tim Van Holder in
4918 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4919 * tests/input.at (Torturing the Scanner): Test the scanner on
4920 an empty input file, which was Tim Van Holder's test case.
4922 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4923 <sys/resource.h> can be included, include sys/time.h and
4924 sys/times.h first, if available. This works around the SunOS
4925 4.1.4 porting bug reported by Bruce Becker in
4926 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4928 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4929 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4932 Merge changes from gnulib. This was prompted because the CVS
4933 snapshot didn't build on Solaris 7 due to strnlen problems.
4935 These changes need to be merged back into gnulib:
4936 * lib/hash.c: Include <stdbool.h> unconditionally.
4937 * m4/onceonly.m4 (m4_quote): New macro.
4938 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4939 Quote AC_FOREACH variable-expansions properly.
4940 The 2003-01-03 obstack.h change also needs merging.
4941 {end of changes requiring merging}
4943 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
4944 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
4945 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,

4947 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
4948 New files, imported from gnulib.
4949 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
4952 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
4953 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
4956 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
4958 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
4959 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
4960 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
4961 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
4962 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
4963 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
4964 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
4965 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
4966 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
4967 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
4968 (jm_PREREQ_ARGMATCH): Remove.
4969 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
4970 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
4972 * src/system.h: Include <stdbool.h> unconditionally.
4974 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
4975 assuming at least C89 in the bitset code for some time now.
4977 2003-03-03 Akim Demaille <akim@epita.fr>
4981 2003-03-02 Akim Demaille <akim@epita.fr>
4983 * doc/bison.texinfo (Table of Symbols): Reactivate the
4984 documentation for %lex-param, and %parse-param.
4986 2003-03-02 Akim Demaille <akim@epita.fr>
4988 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4989 generate verbose error messages.
4990 Use the number of tokens as an upper bound in yytname, as it
4991 cannot be a non terminal.
4993 2003-03-02 Akim Demaille <akim@epita.fr>
4995 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4998 2003-03-02 Akim Demaille <akim@epita.fr>
5000 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
5001 Use them to exercise yycheck overrun.
5002 Based on Andrew Suffield's grammar.
5004 2003-03-02 Akim Demaille <akim@epita.fr>
5006 Create tests/local.at for Bison generic testing macros.
5008 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
5009 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
5011 * tests/calc.at (AT_CHECK_CALC): Adjust.
5012 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
5013 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
5014 * tests/local.at: here.
5015 (AT_COMPILE_CXX): Tags the tests using it as c++.
5016 Ignore the test if CXX is not functional.
5018 2003-03-01 Paul Eggert <eggert@twinsun.com>
5020 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
5021 not loc->end, since loc->end might contain garbage and this leads
5022 to undefined behavior on some platforms.
5023 (id_loc, token_start): Use (IF_LINTed) initial values that do not
5024 depend on *loc, so that the reader doesn't give the the false
5025 impression that *loc is initialized.
5026 (<INITIAL>"%%"): Do not bother setting code_start, since its value
5027 does not survive the return.
5029 2003-03-01 Akim Demaille <akim@epita.fr>
5031 * src/scan-gram.l (code_start): Always initialize it when entering
5032 into yylex, as SC_EPILOGUE is activated *before* the corresponding
5033 yylex invocation. An alternative would be making it static, but
5034 then it starts with the second %%'s beginning, instead of its end.
5036 2003-02-28 Paul Eggert <eggert@twinsun.com>
5038 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
5039 around a UnixWare 7.1.1 porting bug reported by John Hughes in
5040 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
5042 2003-02-26 Paul Eggert <eggert@twinsun.com>
5044 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
5045 Remove Sequent/Pyramid discussion (nobody uses them any more).
5046 Merge VMS and MS-DOS discussion; these ports may well be dead
5047 but let's keep mentioning them for now. Put <> around email
5048 addresses. Add copyright notice.
5050 2003-02-24 Paul Eggert <eggert@twinsun.com>
5052 * data/glr.c (yy_reduce_print): yylineno -> yylno,
5053 to avoid collision with flex use of yylineno.
5054 Problem reported by Bruce Lilly in
5055 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
5056 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
5057 * data/yacc.c (yy_reduce_print): Likewise.
5059 * config/depcomp: Sync with Automake 1.7.3.
5061 2003-02-21 Akim Demaille <akim@epita.fr>
5063 * data/lalr1.cc: Use temporary variables instead of casts to
5064 change integer types.
5065 Suggested by Paul Eggert.
5067 2003-02-21 Akim Demaille <akim@epita.fr>
5069 * doc/bison.texinfo: Use "location" consistently to refer to @n,
5070 to avoid confusions with lalr1.cc's notion of Position.
5071 Suggested by Paul Eggert.
5073 2003-02-20 Akim Demaille <akim@epita.fr>
5075 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
5076 before initial_columns.
5077 (location.hh): Use consistent variable names when defining the
5079 Use "last" so that we subtract from Positions, not from unsigned.
5081 2003-02-20 Akim Demaille <akim@epita.fr>
5083 * data/lalr1.cc (position.hh): New subfile, including the extended
5084 and Doxygen'ed documentation of class Position.
5085 (location.hh): Use it.
5086 Document a` la Doxygen.
5087 With the help of Benoit Perrot.
5089 2003-02-20 Akim Demaille <akim@epita.fr>
5091 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
5093 Redefine AT_YYERROR_SEES_LOC_IF using it.
5094 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
5096 Don't use the location in yy::Parser::error_ and
5097 yy::Parser::print_ when not %locations.
5098 Activate more lalr1.cc tests.
5100 2003-02-19 Akim Demaille <akim@epita.fr>
5102 * data/lalr1.cc: When displaying a line number, be sure to make it
5105 2003-02-19 Akim Demaille <akim@epita.fr>
5107 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
5109 (YYABORT, YYACCEPT, YYERROR): New.
5110 * tests/calc.at: Renable the lalr1.cc test.
5112 2003-02-19 Akim Demaille <akim@epita.fr>
5114 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
5115 error recovery, mixing with/without pops and discarding of the
5118 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
5120 2003-02-17 Paul Eggert <eggert@twinsun.com>
5122 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
5123 * tests/testsuite.at (AT_COMPILE): Use them.
5124 This fixes the testsuite problem reported by Robert Lentz in
5125 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
5127 2003-02-12 Paul Eggert <eggert@twinsun.com>
5129 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
5130 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
5131 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
5132 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
5133 Check for malloc failure, for consistency with yacc.c.
5134 (yytname_size): Remove, for consistency with yacc.c.
5136 The bug still remains in data/lalr1.cc, as I didn't have time
5139 2003-02-06 Akim Demaille <akim@epita.fr>
5141 * configure.ac (GXX): Rename as...
5142 (CXX): this, to keep the original Autoconf semantics.
5144 * data/lalr1.cc: Fix b4_copyright invocations.
5145 If YYDEBUG is not defined, don't depend upon name_ being defined.
5146 (location.hh): Include string and iostream.
5147 (Position::filename): New member.

5156 * tests/testsuite.at (AT_COMPILE_CXX): New.
5157 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
5158 locations in a more synthetic way.
5159 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
5161 Adjust the C locations to match those from Emacs: first column is
5163 Change all the expected results.
5164 Conform to the GCS: simplify the locations when applicable.
5165 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
5166 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
5167 these CPP macros with the m4 macros new defined by...
5168 (AT_CHECK_PUSHDEFS): this, i.e.:
5169 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
5170 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
5172 (AT_CHECK_POPDEFS): Undefine them.
5173 (AT_CHECK_CALC_LALR1_CC): New.
5174 Use it for the first lalr1.cc test.
5176 2003-02-04 Akim Demaille <akim@epita.fr>
5178 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
5179 Location as is defined.
5181 2003-02-04 Akim Demaille <akim@epita.fr>
5183 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
5184 name_ being defined.
5186 2003-02-03 Paul Eggert <eggert@twinsun.com>
5188 * src/gram.h (start_symbol): Remove unused decl.
5190 Use more-consistent naming conventions for local vars.
5192 * src/derives.c (derives_compute): Change type of local var from
5194 * src/gram.c (grammar_rules_partial_print): Likewise.
5195 * src/print.c (print_core): Likewise.
5196 * src/reduce.c (reduce_grammar_tables): Likewise.
5198 * src/gram.c (grammar_dump): Change name of item_number *
5199 local var from r to rp.
5200 * src/nullable.c (nullable_compute): Likewise.
5202 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
5204 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
5205 for symbol or symbol_number var.
5206 * src/reader.c (grammar_start_symbol_set): Likewise.
5207 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
5209 * src/state.c (transitions_to): Likewise.
5210 * src/state.h: Likewise.
5211 * src/tables.c (symbol_number_to_vector_number): Likewise.
5213 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
5216 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
5219 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
5222 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
5223 Use str, not s, for char * var. Use ch, not c, for character var.
5224 Use size for size var.
5226 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
5228 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
5230 * src/uniqstr.h: Likewise.
5232 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
5233 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
5234 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
5235 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
5236 param to have same name as that of enum, so that we don't use
5237 "s" to stand for a non-state.
5239 2003-02-02 Akim Demaille <akim@epita.fr>
5241 * src/scan-skel.l: Scan more than one inert character per yylex
5244 2003-02-01 Paul Eggert <eggert@twinsun.com>
5248 * po/LINGUAS: Add ms.
5250 2003-01-30 Akim Demaille <akim@epita.fr>
5252 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
5254 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5256 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
5259 Changes in response to error report by S. Eken: GLR mode does not
5260 handle negative $ indices or $ indices in embedded rules correctly.
5261 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
5263 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
5264 (b4_rhs_location): Ditto.
5265 (yyfill): New function to copy from stack tree into array
5267 (yyuserAction): Modify to allow incremental move of semantic values
5268 to rhs array when in GLR mode.
5269 Define YYFILL to use in user-defined actions to fill semantic array
5271 Remove dummy use of yystack, as there is now a guaranteed use.
5272 (yydoAction): Modify to allow incremental move of semantic values
5273 to rhs array when in GLR mode.
5274 (yyresolveAction): Ditto.
5275 (yyglrShiftDefer): Update comment.
5276 (yyresolveStates): Use X == NULL for pointers, not !X.
5277 (yyglrReduce): Ditto.
5280 * tests/glr-regr1.at: Rename to ...
5281 * tests/glr-regression.at: Add new regression test for the problems
5282 described above (adapted from S. Eken).
5283 Update copyright notice.
5284 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
5285 * tests/Makefile.am: Ditto.
5287 2003-01-28 Paul Eggert <eggert@twinsun.com>
5289 * data/lalr1.cc: Do not use @output_header_name@ unless
5290 b4_defines_flag is set. This fixes two bugs reported by
5292 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
5293 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
5295 2003-01-21 Paul Eggert <eggert@twinsun.com>
5297 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
5298 we don't need to worry about yyerrlab1 being reported as an
5299 "unused label" by non-GCC C compilers. The downside is that if
5300 locations are used then a couple of statements are duplicated each
5301 time YYERROR is invoked, but the upside is that the warnings
5303 (yyerrlab1): Move code to YERROR.
5304 (yyerrlab2): Remove. Change uses back to yyerrlab1.
5305 This reverts some of the 2002-12-27 change.
5307 2003-01-17 Paul Eggert <eggert@twinsun.com>
5309 * src/output.c (symbol_printers_output): Fix typo that led
5310 to core dump. Problem reported by Antonio Rus in
5311 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
5313 2003-01-13 Akim Demaille <akim@epita.fr>,
5314 Quoc Peyrot <chojin@lrde.epita.fr>,
5315 Robert Anisko <anisko_r@lrde.epita.fr>
5317 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
5318 when the stacks contain one element, as the loop would otherwise
5319 free the last state, and then use the top state (the one we just
5320 popped). This means that the initial elements will not be freed
5321 explicitly, as is the case in yacc.c; it is not a problem, as
5322 these elements have fake values.
5324 2003-01-11 Paul Eggert <eggert@twinsun.com>
5326 * NEWS: %expect-violations are now just warnings, reverting
5327 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
5328 bootstrapping problem reported by Matthias Klose; see
5329 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
5330 * src/conflicts.c (conflicts_print): Likewise.
5331 * tests/conflicts.at (%expect not enough, %expect too much,
5332 %expect with reduce conflicts): Likewise.
5333 * doc/bison.texinfo (Expect Decl): Document this. Also mention
5334 that the warning is enabled if the number of conflicts changes
5335 (not necessarily increases).
5337 * src/getargs.c (version): Update copyright year.
5339 2003-01-09 Akim Demaille <akim@epita.fr>
5341 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
5343 2003-01-08 Paul Eggert <eggert@twinsun.com>
5345 * Makefile.maint (WGETFLAGS):
5346 New macro, containing "-C off" to disable proxy caches.
5347 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
5348 (rel-check): Use $(WGET) instead of wget.
5350 2003-01-06 Paul Eggert <eggert@twinsun.com>
5352 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
5353 the GLR paper of Scott, Johnstone and Hussain.
5355 2003-01-04 Paul Eggert <eggert@twinsun.com>
5357 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
5358 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
5359 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
5360 (EXTRA_LIBRARIES): New var, for liby.a.
5361 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
5362 (EXTRA_SCRIPTS): New var, for yacc.
5364 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
5365 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
5366 Problem reported by Nelson H. F. Beebe.
5368 2003-01-03 Paul Eggert <eggert@twinsun.com>
5370 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
5371 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
5372 when compiling Bison 1.875's `bitset bset = obstack_alloc
5373 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
5375 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
5376 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
5377 grow to a huge size with typical invocation.
5379 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
5380 Use the pattern recommended by Autoconf 2.57, except also protect
5381 against double-definition.
5382 * src/system.h: Likewise.
5383 Portability issues reported by Nelson H. F. Beebe.
5385 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
5386 All uses changed. Provide a definition in both C and C++.
5387 (yytrue, yyfalse): Define even if defined (__cplusplus).
5389 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
5390 Reported by Nelson H. F. Beebe.
5392 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
5394 2003-01-02 Paul Eggert <eggert@twinsun.com>
5396 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
5397 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
5398 Bug reported by Nelson H. F. Beebe.
5400 2003-01-01 Paul Eggert <eggert@twinsun.com>
5404 2002-12-30 Paul Eggert <eggert@twinsun.com>
5406 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
5408 (<INITIAL>","): Here. This causes stray "," to be treated
5411 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
5412 last brace in braced code when not in Yacc mode, for compatibility
5413 with Bison 1.35. This resurrects the 2001-12-15 patch to
5416 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
5417 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
5419 2002-12-28 Paul Eggert <eggert@twinsun.com>
5421 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
5422 that of SYM's type. This fixes Debian bug 168069, reported by
5425 2002-12-28 Paul Eggert <eggert@twinsun.com>
5429 Switch back to the Yacc style of conflict reports, undoing some
5430 of the 2002-07-30 change.
5431 * doc/bison.texinfo (Understanding): Use Yacc style for
5432 conflict reports. Also, use new way of locating rules.
5433 * src/conflicts.c (conflict_report):
5434 Renamed from conflict_report_yacc, removing the old
5435 'conflict_report'. Translate the entire conflict report at once,
5436 so that we don't assume that "," has the same interpretation in
5438 (conflicts_output): Use Yacc-style conflict report for each state,
5439 instead of our more-complicated style.
5440 (conflicts_print): Use Yacc-style conflict report, except print
5441 the input file name when not emulating Yacc.
5442 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5443 Conflicted Reduction, %expect not enough, %expect too much,
5444 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
5445 * tests/existing.at (GNU Cim Grammar): Likewise.
5446 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
5448 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
5449 fatal): Don't invoke fflush; it's not needed and it might even be
5450 harmful for stdout, as stdout might not be open.
5451 * src/reduce.c (reduce_print): Likewise.
5453 2002-12-27 Paul Eggert <eggert@twinsun.com>
5455 Fix a bug where error locations were not being recorded correctly.
5456 This problem was originally reported by Paul Hilfinger in
5457 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
5459 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5460 top of the location stack's error locations.
5461 (yyerrlab): Set it. When discarding a token, push its location
5462 onto yylerrsp so that we don't lose track of the error's end.
5463 (yyerrlab1): Now is only the target of YYERROR, so that we can
5464 properly record the location of the action that failed. For GCC
5465 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5466 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5467 (yyerrlab2): New label, which yyerrlab now falls through to.
5468 Compute the error's location by applying YYLLOC_DEFAULT to
5469 the locations of all the symbols that went into the error.
5470 * doc/bison.texinfo (Location Default Action): Mention that
5471 YYLLOC_DEFAULT is also invoked for syntax errors.
5472 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5473 Error locations include the locations of all the tokens that were
5474 discarded, not just the last token.
5476 2002-12-26 Paul Eggert <eggert@twinsun.com>
5478 * src/files.c: Include quote.h.
5479 (compute_output_file_names): Warn if we detect conflicting
5480 outputs to the same file. This should catch the misunderstanding
5481 exemplified by Debian Bug 165349, reported by Bruce Stephens..
5483 * src/conflicts.c (conflicts_print): If the user specifies
5484 "%expect N", report an error if there are any reduce/reduce
5485 conflicts. This is what the manual says should happen.
5486 This fixes Debian bug 130890, reported by Anthony DeRobertis.
5487 * tests/conflicts.at (%expect with reduce conflicts): New test.
5489 Don't use m4_include on relative file names, as it doesn't work as
5490 desired if there happens to be a file with that name under ".".
5492 * m4sugar/version.m4: Remove; it was included but it wasn't used.
5493 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
5494 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
5495 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
5496 * src/output.c (output_skeleton): Use full path names when
5497 specifying a file to include; don't rely on include path, as
5498 it's unreliable when the working file contains a file with
5501 2002-12-25 Paul Eggert <eggert@twinsun.com>
5503 Remove obsolete references to bison.simple and bison.hairy.
5504 Problem mentioned by Aubin Mahe in
5505 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
5506 * data/glr.c: Comment fix.
5507 * doc/bison.1: Remove references. Also, mention "yacc".
5509 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
5512 * src/parse-gram.y (declaration): Use enum "report_states" rather
5513 than its numeric value 1.
5515 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
5516 opening a new one. This fixes Debian bug 165349, reported by
5519 2002-12-24 Paul Eggert <eggert@twinsun.com>
5523 * Makefile.maint (cvs-update): Don't assume that the shell
5524 supports $(...), as Solaris sh doesn't.
5526 * src/parse-gram.y (lloc_default): Remove test for empty
5527 nonterminals at the end, since it didn't change the result.
5529 2002-12-24 Paul Eggert <eggert@twinsun.com>
5531 If the user does not define YYSTYPE as a macro, Bison now declares it
5532 using typedef instead of defining it as a macro. POSIX requires this.
5533 For consistency, YYLTYPE is also declared instead of defined.
5535 %union directives can now have a tag before the `{', e.g., the
5536 directive `%union foo {...}' now generates the C code
5537 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5538 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5539 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5540 instead of `yyltype'.
5542 `yystype' and `yyltype' are now obsolescent macros instead of being
5543 typedefs or tags; they are no longer documented and will be
5544 withdrawn in a future release.
5546 * data/glr.c (b4_location_type): Remove.
5547 (YYSTYPE): Renamed from yystype.
5548 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5549 (struct YYLTYPE): Renamed from struct yyltype.
5550 (YYLTYPE): Renamed from yyltype.
5551 (yyltype, yystype): New (and obsolescent) macros,
5552 for backward compatibility.
5553 * data/yacc.c: Likewise.
5555 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5556 does not specify a union tag. This is for compatibility with
5559 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5560 const *, since it is now modified by stripping surrounding { }.
5561 (current_braced_code): Remove.
5562 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5563 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5564 trailing " {...}". Now of type <chars>.
5565 (grammar_declaration): Adjust to bundled tokens.
5566 (code_content): Remove; stripping is now done by add_param.
5567 (print_token_value): Print contents of bundled tokens.
5568 (token_name): New function.
5570 * src/reader.h (braced_code, current_braced_code): Remove.
5571 (token_name): New decl.
5573 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5574 token_type, not braced_code code_kind. All uses changed.
5575 (SC_PRE_CODE): New state, for scanning after a keyword that
5576 has (or usually has) an immediately-following braced code.
5577 (token_type): New local var, to keep track of which token type
5578 to return when scanning braced code.
5579 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5580 <INITIAL>"%parse-param", <INITIAL>"%printer",
5581 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5582 instead of returning a token type immediately.
5583 (<INITIAL>"{"): Set token type.
5584 (<SC_BRACED_CODE>"}"): Use it.
5585 (handle_action_dollar, handle_action_at): Now returns bool
5586 indicating success. Fail if ! current_rule; this prevents a core dump.
5587 (handle_symbol_code_dollar, handle_symbol_code_at):
5588 Remove; merge body into caller.
5589 (handle_dollar, handle_at): Complain in invalid contexts.
5591 * NEWS, doc/bison.texinfo: Document the above.
5592 * NEWS: Fix years and program names in copyright notice.
5594 2002-12-17 Paul Eggert <eggert@twinsun.com>
5596 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5597 Reporting, Table of Symbols): Omit mentions of %lex-param and
5598 %parse-param from the documentation for now.
5600 2002-12-15 Paul Eggert <eggert@twinsun.com>
5602 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5603 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5604 lookahead symbol, and which sets yychar in parser actions) and it
5605 disagreed with the Bison documentation. Bug
5606 reported by Andrew Walrond.
5608 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5609 as the caller now does that.
5610 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5611 (YYEMPTY): Parenthesize right hand side, since others use it.
5612 (yyparse): Don't assume that our generated code is the only code
5615 2002-12-13 Paul Eggert <eggert@twinsun.com>
5619 POSIX requires a "yacc" command.
5620 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.

5650 usually aren't needed and are a sign of trouble.
5652 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5654 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5655 the pointer DSET returned by malloc; this isn't portable.

5676 symbol_number_to_vector_number): Likewise.
5678 * src/gram.h (int_of_rule_number): Remove; no longer used.
5680 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,

5686 * src/muscle_tab.c (muscle_m4_output):
5687 Now inline. Return bool, not int.

5700 hash_symbol_hasher): Likewise.
5701 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5702 * src/muscle_tab.c (muscles_m4_output):
5703 Use new functions instead of casting old functions unportably.
5704 * src/state.c (state_hash_new): Likewise.
5705 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5706 symbols_token_translations_init):
5708 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5710 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5711 var instead of casting to long, to avoid casts.

5713 have to worry about alloca.
5714 * src/state.c (state_hash_lookup): Likewise.
5716 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5717 local var instead of casting to unsigned char, to avoid casts.

5720 STATE_ALLOC): Remove.
5721 (transitions_new, errs_new, reductions_new, state_new): Use malloc

5734 (symbol_processor): Remove.
5735 (symbols_do): Remove decl; now static.
5737 * src/system.h (alloca): Remove; decl no longer needed.
5738 (<stddef.h>): Include, for offsetof.
5739 (<inttypes.>, <stdint.h>): Include if available.
5740 (uintptr_t): New type, if system lacks it.
5741 (CALLOC, MALLOC, REALLOC): New macros.
5742 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5745 * src/tables.c (table_size): Now int, to pacify GCC.
5746 (table_grow, table_ninf_remap): Use signed table size.
5747 (save_row): Don't bother initializing locals when not needed.
5748 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
5749 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
5751 * src/vcg.h: Correct misspellings.
5753 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
5756 * src/getargs.c (getargs): Don't assume EOF == -1.
5758 2002-12-09 Paul Eggert <eggert@twinsun.com>
5760 Change identifier spellings to avoid collisions with names
5761 that are reserved by POSIX.
5763 Don't use names ending in _t, since POSIX reserves them.
5764 For consistency, remove _e and _s endings -- they're weren't
5765 needed to remove ambiguity. All uses changed.
5766 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5767 turn was just renamed from struniq_t.
5768 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
5769 which in turn was just renamed from struniq_processor_t.

5841 value_t_as_yystype -> value_as_yystype.
5843 Don't include <errno.h> in the mainstream code, since it
5844 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5845 * lib/get-errno.c, lib/get-errno.h: New files.
5846 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
5848 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

5855 * src/system.h: Do not include <errno.h>.
5856 (TAB_EXT): Renamed from EXT_TAB.
5857 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
5859 Avoid str[a-z]*, since <string.h> reserves that name space.
5860 Change all instances of "struniq" in names to "uniqstr", and
5861 likewise for "STRUNIQ" and "UNIQSTR".
5862 * src/uniqstr.c: Renamed from src/struniq.c.
5863 * src/uniqstr.h: Renamed from src/struniq.h.

5899 for consistency with other names.
5900 * lib/timevar.h (timevar_report): New decl.
5901 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5904 Sort include-file uses.
5906 Reorder all include files under src to be in the order "system.h".
5907 then the ../lib include files in angle brackets (alphabetized),
5908 then the . include files in double-quotes (alphabetized). Fix
5909 dependency breakages encountered in this process, as follows:
5910 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5911 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5912 * src/state.h: Include "symtab.h".
5914 2002-12-08 Paul Eggert <eggert@twinsun.com>
5916 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5917 since this causes problems when __file__ contains character
5918 sequences like "@" that are treated specially by src/scan-skel.l.
5919 Instead, just use the file's basename. This fixes the bug
5920 reported by Martin Mokrejs in
5921 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5923 2002-12-06 Paul Eggert <eggert@twinsun.com>
5925 Add support for rules that do not have trailing semicolons, as
5926 POSIX requires. Improve the quality of locations in Bison
5929 * src/location.c: Include <quotearg.h>.
5930 (empty_location): Now const.
5931 (location_print): New function. Follow the recommendation of the
5932 GNU Coding Standards for locations that span file boundaries.
5933 * src/location.h: Do not include <quotearg.h>; no longer needed.
5934 (boundary): New type.
5935 (location_t): Use it. This allows locations to span file boundaries.
5936 All member uses changed: file -> start.file or end.file (as needed),
5937 first_line -> start.line, first_column -> start.column,
5938 last_line -> end.line, last_column -> end.column.
5939 (equal_boundaries): New function.
5940 (LOCATION_RESET, LOCATION_STEP): Remove.
5941 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5942 (empty_location): Now const.
5943 (location_print): New decl.
5944 * src/parse-gram.y (lloc_default): New function, which handles
5945 empty locations more accurately.
5946 (YYLLOC_DEFAULT): Use it.
5947 (%token COLON): Remove.
5948 (%token ID_COLON): New token.
5950 (declarations, rules): Remove trailing semicolon.

5963 the work. All uses removed.
5964 (scanner_cursor): New var.
5965 (adjust_location): Renamed from extend_location. It now sets
5966 *loc and adjusts the scanner cursor. All uses changed.
5967 Don't bother testing for CR.
5968 (handle_syncline): Remove location arg; now updates scanner cursor.
5969 All callers changed.
5970 (unexpected_end_of_file): Now accepts start boundary of token or
5971 comment, not location. All callers changed. Update scanner cursor,
5973 (SC_AFTER_IDENTIFIER): New state.
5974 (context_state): Renamed from c_context. All uses changed.
5975 (id_loc, code_start, token_start): New local vars.
5976 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5977 processing of Yacc white space and equivalents here.
5978 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5979 instead of returning ID immediately, since we need to search for
5981 (<INITIAL>"'", "\""): Save token_start.
5982 (<INITIAL>"%{", "{", "%%"): Save code_start.
5983 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5984 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5985 BEGIN context_state at end, not INITIAL.
5986 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5987 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5988 Return correct token start.
5989 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5990 the start of a character, string or multiline comment is found.
5991 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5992 Reduction): Adjust reported locations to match the more-precise
5993 results now expected.
5994 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5995 * tests/reduce.at (Useless Rules, Reduced Automaton,
5996 Underivable Rules): Likewise.
5997 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5998 or "|"' now that so many other tokens are allowed by the new grammar.
6000 * src/complain.h (current_file): Remove duplicate decl;
6001 current_file is now owned by files.h.
6002 * src/complain.c, src/scan-gram.l: Include files.h.
6004 2002-12-06 Paul Eggert <eggert@twinsun.com>
6006 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
6007 promotes to int; it might be unsigned int.
6008 * data/yacc.c (yy_reduce_print): Likewise.
6010 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
6011 be #defined in the prologue, not in the Bison declarations.
6012 This fixes Debian Bug 102878, reported by Shaul Karl.
6014 2002-12-02 Paul Eggert <eggert@twinsun.com>
6016 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
6017 * lib/strtoul.c: New file, from gnulib.
6018 This fixes a porting bug reported by Peter Klein in
6019 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
6021 2002-11-30 Paul Eggert <eggert@twinsun.com>
6023 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
6024 and put only a forward declaration in the prologue. This is for
6025 consistency with the other scanner helper functions.
6027 Type clashes now generate warnings, not errors, since it
6028 appears that POSIX may allow some grammars with type clashes.
6029 * src/reader.c (grammar_current_rule_check): Warn about
6030 type clashes instead of complaining.
6031 * tests/input.at (Type Clashes): Expect warnings, not complaints.
6033 Add Yacc library, since POSIX requires it.
6034 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
6035 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
6036 * lib/main.c, lib/yyerror.c: New files.
6038 gram_error can be static; it need not be extern.
6039 * src/reader.h (gram_error): Remove decl.
6040 * src/parse-gram.y (gram_error): Now static. Add static decl.
6041 (print_token_value): Omit parameter names from forward decl,
6044 2002-11-29 Paul Eggert <eggert@twinsun.com>
6046 * doc/bison.texinfo: Emphasize that yylex and yyerror must
6047 be declared before being used. E.g., one should typically
6048 declare them in the prologue. Use GNU coding style in examples.
6049 Put "const" consistently after the type it modifies. Mention
6050 that C99 supports "inline". Mention that yyerror traditionally
6053 %parse-param and %lex-param now take just one argument, the
6054 declaration; the argument name is deduced from the declaration.
6056 * doc/bison.texinfo (Parser Function, Pure Calling, Error
6057 Reporting, Table of Symbols): Document this.
6058 * src/parse-gram.y (add_param): New function.
6060 (declaration): Implement new rule for %parse-param and %lex-param.
6061 * src/scan-gram.l: "," now elicits a warning, rather than being
6062 a token; this is more compatible with byacc.
6063 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
6065 2002-11-27 Paul Eggert <eggert@twinsun.com>
6067 Rename identifiers to avoid real and potential collisions.
6069 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
6070 to avoid collision with lex macro described by Bruce Lilly in
6071 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
6072 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
6073 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
6074 * src/parse-gram.y (print_token_value): Renamed from yyprint.
6076 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
6077 The name "yycontrol" violates the name space rules, and this stuff
6078 wasn't being used anyway.
6079 (input): Remove action; this stuff wasn't being used.
6080 (gram_error): Rename local variable yylloc -> loc.
6081 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
6082 (YY_DECL): Don't use "yy" at start of local variables.
6083 All uses changed, e.g., yylloc -> loc.
6084 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
6085 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.

6092 2002-11-24 Paul Eggert <eggert@twinsun.com>
6096 * tests/actions.at (Actions after errors): Use an output format
6097 more similar to that of the Printers and Destructors test.
6098 Test the position of the ';' token too.
6099 (Printers and Destructors): Likewise.
6100 (Printers and Destructors: %glr-parser): Remove for now, to avoid
6101 unnecessarily alarming people when the test fails.
6103 * data/yacc.c (yyerrlab1): Move this label down, so that the
6104 parser does not discard the lookahead token if the user code
6105 invokes YYERROR. This change is required for POSIX conformance.
6107 * lib/error.c: Sync with gnulib.
6109 2002-11-22 Paul Eggert <eggert@twinsun.com>
6111 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

6115 2002-11-20 Paul Eggert <eggert@twinsun.com>
6117 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
6119 2002-11-20 Paul Eggert <eggert@twinsun.com>
6121 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
6122 should use `if (! x) abort ();' rather than `assert (x);', and
6123 anyway it's one less thing to worry about configuring.
6125 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
6126 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
6127 and replace all instances of assert with abort.
6128 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
6129 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
6131 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
6132 yyresolveAction, yyprocessOneStack): Use abort rather than assert.

6143 symbol_pack): Likewise.
6144 * src/tables.c (conflict_row, pack_vector): Likewise.
6145 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,

6147 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
6148 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
6150 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
6151 (ARGMATCH_CONSTRAINT): New macro.
6152 (ARGMATCH_ASSERT): Use it.
6154 * src/system.h (verify): New macro.
6155 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
6157 * src/tables.c (tables_generate): Likewise.
6159 * src/struniq.c (struniq_assert): Now returns void, and aborts
6160 if the assertion is false.
6161 (struniq_assert_p): Remove.
6162 * src/struniq.h: Likewise.
6164 2002-11-18 Paul Eggert <eggert@twinsun.com>
6166 * data/glr.c (yygetLRActions): Replace `yyindex' with
6167 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
6168 This fixes the regression with Sun ONE Studio 7 cc that I reported in
6169 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
6171 2002-11-18 Akim Demaille <akim@epita.fr>
6173 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
6175 From Tim Van Holder.
6177 2002-11-17 Paul Eggert <eggert@twinsun.com>
6179 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
6180 to "SyntaxError" for consistency with my 2002-11-15 change.
6182 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
6183 not define to {}, since this breaks the common use of `YYDPRINTF
6184 ((...));' if a single statement is desired (e.g. before `else').
6185 Work around GCC warnings by surrounding corresponding calls with
6187 (yyhasResolvedValue): Remove unused function.
6188 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
6190 (yyreportSyntaxError): Renamed from yyreportParseError.
6191 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
6193 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
6194 extern when possible. Remove unused initializations.
6196 2002-11-16 Akim Demaille <akim@epita.fr>
6198 Augment the similarity between GLR and LALR traces.
6200 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
6201 (YY_REDUCE_PRINT): New.
6202 (yyparse): Use them.
6203 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
6205 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
6206 state reached after the reduction/recovery, since...
6207 (yyparse, yyprocessOneStack): Report the state we are entering in.
6209 2002-11-16 Akim Demaille <akim@epita.fr>
6211 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
6212 Add support for --trace=skeleton.
6213 * src/scan-skel.l: %option debug.
6214 Scan strings of non-@ or \n instead of character by character.
6215 (scan_skel): Handle trace_skeleton.
6217 (@output_parser_name@, @output_header_name@): ``Restore'' their
6218 support (used to be M4 macros).
6219 * data/yacc.c: Quote larger chunks, a la glr.c.
6220 * data/lalr1.cc: Likewise.
6221 The header guards are no longer available, so use some other
6222 string than `YYLSP_NEEDED'.
6224 2002-11-16 Akim Demaille <akim@epita.fr>
6226 Make the ``Printers and Destructors'' test more verbose, taking
6227 `yacc.c''s behavior as (possibly wrong) reference.
6229 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
6230 instead of fprint on stdout.
6231 Set and report the last_line of the symbols.
6232 Consistently display values and locations.
6234 2002-11-16 Paul Eggert <eggert@twinsun.com>
6236 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
6238 2002-11-15 Paul Eggert <eggert@twinsun.com>
6240 * tests/actions.at (Actions after errors): New test case.
6242 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
6243 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
6244 tests/action.at, tests/calc.at, tests/conflicts.at,
6245 tests/cxx-type.at, tests/regression.at:
6246 "parse error" -> "syntax error" for POSIX compatibility.
6247 "parsing stack overflow..." -> "parser stack overflow" so
6248 that code matches Bison documentation.
6250 2002-11-15 Akim Demaille <akim@epita.fr>
6252 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
6253 take two BRACED_CODE, not two string_content.
6254 Free the scanner's obstack when we are done.
6255 (code_content): New.
6256 * tests/calc.at: Adjust.
6257 * doc/bison.texinfo: Adjust.
6258 Also, make sure to include the `,' for these declarations.
6260 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
6262 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
6263 definition; avoids potential autoreconf problems.
6265 2002-11-15 Akim Demaille <akim@epita.fr>
6267 Always check the value returned by yyparse.
6269 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
6270 returned by yyparse.
6271 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
6273 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
6274 returned by yyparse.
6276 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6278 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
6281 2002-11-14 Paul Eggert <eggert@twinsun.com>
6283 * src/output.c (output_skeleton): Call xfopen instead of
6284 duplicating xfopen's body.
6286 Fix bugs reported by Nelson H. F. Beebe in
6287 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
6289 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
6290 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
6291 Group compiler. Instead, use "$CC -E bar.c". Include the .h
6292 file twice in the grammar, as an extra check.
6294 * tests/input.at (Torturing the Scanner): Surround the
6295 backslash-newline tests with "#if 0", to make it less likely that
6296 we'll run into compiler bugs. Bring back solitary \ inside
6297 comment, but add a closing comment to work around HP C bug. Don't
6298 test backslash-newline in C character constant.
6300 2002-11-14 Akim Demaille <akim@epita.fr>
6302 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
6303 status of the compiler.
6304 Calling `exit 1' is no longer needed.
6305 Reported by Nelson H. F. Beebe.
6307 2002-11-14 Akim Demaille <akim@epita.fr>
6309 * tests/atlocal.in (CPPFLAGS): We have config.h.

6322 * doc/bison.texinfo: Various formatting changes (alignments in
6323 samples, additional @group/@end group, GCS in samples.
6324 Use @deffn instead of simple @table to define the directives,
6325 macros, variables etc.
6327 2002-11-13 Paul Eggert <eggert@twinsun.com>
6329 Fix some bugs reported by Albert Chin-A-Young in
6330 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
6332 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
6333 -o c"; the HP C compiler chatters during compilation.
6334 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
6335 * tests/headers.at (export YYLTYPE): Likewise.
6337 * tests/input.at (Torturing the Scanner): Remove lines containing
6338 solitary backslashes, as they tickle a bug in the HP C compiler.
6340 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
6341 comments, since they're not portable. Use GNU coding style.
6343 2002-11-13 Akim Demaille <akim@epita.fr>
6345 * data/yacc.c: Leave bigger chunks of quoted text.
6346 (YYDSYMPRINTF): New.
6347 Use it to report symbol activities.
6348 * data/glr.c (YYDSYMPRINTF): New.
6351 2002-11-12 Paul Eggert <eggert@twinsun.com>
6355 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
6356 (yyglrReduce): Return yyok, not 0.
6357 This should avoid the enumerated-type warnings reported
6358 by Nelson H. F. Beebe in
6359 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
6361 * lib/bbitset.h (BITSET_INLINE): Remove.
6362 * lib/bitset.h [! BITSET_INLINE]: Remove.
6363 (bitset_set, bitset_reset, bitset_test): Rename local vars
6364 to avoid shadowing warnings by GCC.
6366 * data/glr.c (inline): Remove #define. It's the user's
6367 responsibility to #define it away, just like 'const'.
6368 This fixes one of the bugs reported by Nelson H. F. Beebe in
6369 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
6371 * Makefile.maint (po-check): Scan .l and .y files instead of the
6372 .c and the .h files that they generate. This fixes the bug
6373 reported by Tim Van Holder in:
6374 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
6375 Look for N_ as well as for _. Try to avoid matching #define for
6377 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
6378 src/system.h. Add src/parse-gram.y, src/scan-gram.l.

6380 do not confuse xgettext.
6382 * src/struniq.h (struniq_new): Do not declare the return type
6383 to be 'const'; this violates the C standard.
6384 * src/struniq.c (struniq_new): Likewise.
6386 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
6388 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

6420 * data/glr.c (yystos): New.
6421 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
6423 (yyval): Don't define it, it is handled via M4.
6424 (yyrecoverParseError): Free verbosely the discarded symbols.
6425 * data/yacc.c (yysymprint): Remove, rather...
6426 (b4_yysymprint_generate): invoke.
6427 * data/c.m4 (b4_yysymprint_generate): New.
6428 Accept pointers as arguments, as opposed to the version from
6430 (b4_yydestruct_generate): Likewise.
6431 * tests/cations.at (Printers and Destructors): Use Bison directives

6437 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
6438 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
6439 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
6440 it against YYEMPTY and so forth), work on yytoken (i.e., set
6441 it to YYEMPTY etc.).
6442 (yydestruct): Replace with a b4_yydestruct_generate invocation.
6443 (b4_symbol_actions): Remove.
6444 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
6445 for 0, end-of-input.

6451 2002-11-12 Akim Demaille <akim@epita.fr>

6530 2002-11-11 Paul Eggert <eggert@twinsun.com>
6532 Revamp to fix many (but not all) of the C- and M4-related quoting
6533 problems. Among other things, this fixes the Bison bug reported
6534 by Jan Hubicka when processing the Bash grammar; see:
6535 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6537 Use new @ escapes consistently. Represent brackets with @{ and @}
6538 rather than @<:@ and @:>@, since this works a bit better with dumb
6539 editors like vi. Represent @ with @@, since @ is now consistently
6540 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6541 __ofile__, to avoid unexpected expansions. Similarly, use @output
6542 rather than #output.
6544 * data/c.m4 (b4_copyright): Omit file name from comment, since
6545 the file name could contain "*/".
6546 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6547 be quoted. All uses changed.
6549 * data/glr.c: Use new @ escapes consistently.
6550 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6551 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6552 Remove, since they couldn't handle arbitrary characters in file
6554 * data/lalr1.cc: Likewise.
6555 * data/yacc.c: Likewise.
6557 * src/files.c (output_infix): Remove; all uses removed.
6558 * src/files.h: Likewise.
6560 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6561 mishandled funny characters in file names, and anyway it isn't
6563 * data/yacc.c: Likewise.
6564 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6566 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6567 * data/yacc.c: Likewise.
6569 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6571 (muscle_init): Quote filename as a C string.
6572 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6573 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6574 * src/output.c (escaped_file_name_output): New function.
6575 (prepare_symbols): Quote tokens for M4.
6576 (prepare): Don't insert output_infix, output_prefix,
6577 output_parser_name, output_header_name; this is now down by scan-skel.
6578 Insert skeleton as a C string.
6580 * src/output.c (user_actions_output, symbol_destructors_output,
6581 symbol_printers_output): Quote filenames for C and M4.
6582 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6584 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
6585 escapes other than \\ and \'; this simplifies the code.
6586 (<SC_STRING>): Likewise, for \\ and \".
6587 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6588 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6589 Use new escapes @{ and @} for [ and ].
6591 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6592 them with auto vars.
6593 Switch to new escape scheme, where @ is the escape character uniformly.
6594 Abort if a stray escape character is found. Avoid unbounded input
6595 buffer when parsing non-escaped text.
6597 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6598 __oline__, #output, $@, and @{ do not have unintended meanings.
6600 2002-11-09 Paul Eggert <eggert@twinsun.com>
6602 Fix the test failure due to GCC warnings described in
6603 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6604 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6605 evaluate to 0 if it's impossible for NINF to be in the respective
6607 (yygetLRActions, yyrecoverParseError): Use them.
6609 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6610 counted in the token inserted at end of file. Now takes
6611 location_t *, not location_t, so that the location can be
6612 adjusted. All uses changed.
6614 * tests/regression.at (Invalid inputs): Adjust wording in
6615 diagnostic to match the new behavior.
6617 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6618 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6619 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6620 abort ();'. This reduces the runtime of the "Many lookaheads"
6621 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
6624 2002-11-07 Paul Eggert <eggert@twinsun.com>
6626 * src/parse-gram.y (CHARACTER): Remove unused token.
6629 * src/scan-gram.l: Remove stack option. We no longer use the
6630 stack, since the stack was never deeper than 1; instead, use the
6631 new auto var c_context to record the stacked value.
6633 Remove nounput option. At an unexpected end of file, we now unput
6634 the minimal input necessary to end cleanly; this simplifies the
6637 Avoid unbounded token sizes where this is easy.
6639 (unexpected_end_of_file): New function.
6640 Use it to systematize the error message on unexpected EOF.
6641 (last-string): Now auto, not static.
6642 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
6643 (scanner_last_string_free): Remove; not used.

6645 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
6646 not the (never otherwised-used) CHARACTER.
6648 2002-11-07 Akim Demaille <akim@epita.fr>
6650 Let yyerror always receive the msg as last argument, so that
6651 yyerror can be variadic.
6653 * data/yacc.c (b4_yyerror_args): New.
6654 Use it when calling yyerror.
6655 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

6661 2002-11-06 Akim Demaille <akim@epita.fr>
6663 #line should have quoted strings.
6664 Ideally, this should be done by m4_quotearg.
6666 * src/scan-skel.l: Include quotearg.h.
6668 * src/output.c (symbol_printers_output)
6669 (symbol_destructors_output): Quote the file name.
6671 2002-11-06 Akim Demaille <akim@epita.fr>

6686 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
6688 2002-11-06 Akim Demaille <akim@epita.fr>
6690 * src/main.c (main): Free `infile'.
6691 * src/scan-gram.l (handle_syncline): New.
6693 * src/output.c (user_actions_output, symbol_destructors_output)
6694 (symbol_printers_output): Use the location's file name, not
6696 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6698 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6700 * src/tables.c (matching_state): Don't allow states to match if
6701 either has GLR conflict entries.
6703 2002-11-05 Paul Eggert <eggert@twinsun.com>
6705 * src/scan-gram.l: Use more accurate diagnostics, e.g.
6706 "integer out of range" rather than "invalid value".
6707 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
6710 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
6711 Also, remove one static variable in the scanner.
6713 * src/scan-gram.l (braces_level): Now auto, not static.
6714 Initialize to zero if the compiler is being picky.
6715 (INITIAL): Clear braces_level instead of incrementing it.
6716 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
6717 as POSIX 1003.1-2001 requires.
6718 * src/system.h (IF_LINT): New macro, taken from coreutils.
6719 * configure.ac: Define "lint" if --enable-gcc-warnings.
6721 2002-11-05 Akim Demaille <akim@epita.fr>
6723 * src/scan-gram.l: When it starts with `%', complain about the
6724 whole directive, not just that `invalid character: %'.
6726 2002-11-04 Akim Demaille <akim@epita.fr>
6728 * Makefile.maint: Update from Autoconf.
6729 (update, cvs-update, po-update, do-po-update): New.
6731 2002-11-04 Akim Demaille <akim@epita.fr>

6735 Have yyerror `use' its arguments.
6736 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
6737 returns true when location & yacc & pure & parse-param.
6738 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
6740 2002-11-04 Akim Demaille <akim@epita.fr>
6742 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
6744 * src/scan-gram.l: Use [\'] instead of ['] to pacify
6747 Use quote, not quote_n since LOCATION_PRINT no longer uses the
6750 2002-11-03 Paul Eggert <eggert@twinsun.com>
6752 * src/reader.c (get_merge_function, grammar_current_rule_check):
6753 Use consistent diagnostics for reporting type name clashes.
6754 Quote the types with <>, for consistency with Yacc.
6755 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
6757 2002-11-03 Akim Demaille <akim@epita.fr>
6759 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):

6766 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
6767 (b4_lpure_formals): New.
6768 Use b4_identification.
6769 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
6770 b4_user_formals and b4_user_args.
6771 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
6772 (yyreportAmbiguity): When using a pure parser, also need
6773 the location, and the parse-params.
6775 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
6776 When using a pure parser, also need the parse-params.
6778 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
6779 (%pure-parser + %parse-param) LALR and GLR parsers.
6780 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
6781 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
6782 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
6783 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

6788 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
6789 (Error Reporting): Adjust to these new directives.
6790 Document %error-verbose, deprecate YYERROR_VERBOSE.
6792 2002-11-03 Akim Demaille <akim@epita.fr>
6794 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
6795 AT_CHECK_CALC_GLR invocations to use % directives, instead of
6796 command line options.
6797 * tests/cxx-type.at: Formatting changes.
6799 2002-11-03 Paul Eggert <eggert@twinsun.com>
6801 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
6802 to count columns correctly, and to check for invalid inputs.
6804 Use mbsnwidth to count columns correctly. Account for tabs, too.
6806 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
6807 (extend_location): New function.
6810 Handle CRLF in C code rather than in Lex code.
6811 (YY_INPUT): New macro.
6812 (no_cr_read): New function.
6814 Scan UCNs, even though we don't fully handle them yet.
6815 (convert_ucn_to_byte): New function.
6817 Handle backslash-newline correctly in C code.
6818 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
6819 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
6821 (tag, splice): New EREs. Do not allow NUL or newline in tags.
6822 Use {splice} wherever C allows backslash-newline.
6823 YY_STEP after space, newline, vertical-tab.
6824 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
6826 (letter, id): Don't assume ASCII; e.g., spell out a-z.
6828 ({int}, handle_action_dollar, handle_action_at): Check for integer
6831 (YY_STEP): Omit trailing semicolon, so that it's more like C.
6833 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
6834 as well as \000. Check for UCHAR_MAX, not 255.
6835 Allow \x with an arbitrary positive number of digits, as in C.
6836 Check for overflow here.
6837 Allow \? and UCNs, for compatibility with C.
6839 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
6840 with quote slot used by complain_at.
6842 * tests/input.at: Add tests for backslash-newline, m4 quotes
6843 in symbols, long literals, and funny escapes in strings.
6845 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
6846 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

6859 2002-11-02 Paul Eggert <eggert@twinsun.com>
6861 * src/reader.c: Don't include quote.h; not needed.
6862 (get_merge_function): Reword warning to be consistent with
6863 type clash diagnostic in grammar_current_rule_check.
6865 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
6866 bug in trigraph handling.
6868 * src/output.c (prepare_symbols): When printing token names,
6869 escape "[" as "@<:@" and likewise for "]".
6871 * src/system.h (errno): Remove declaration, as we are now
6872 assuming C89 or better, and C89 guarantees errno.
6874 2002-10-30 Paul Eggert <eggert@twinsun.com>
6876 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
6877 Check for close failures.
6878 * src/files.h (xfclose): Return void, not int, since it always
6880 * src/files.c (xfclose): Likewise. Report I/O error if ferror
6882 * src/output.c (output_skeleton): Use xfclose rather than fclose
6883 and ferror. xfclose now checks ferror.
6885 * data/glr.c (YYLEFTMOST_STATE): Remove.
6886 (yyreportTree): Use a stack-based leftmost state. This avoids
6887 our continuing battles with bogus warnings about initializers.
6889 2002-10-30 Akim Demaille <akim@epita.fr>
6891 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
6894 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6896 * tests/glr-regr1.at: New test for reported regressions.
6897 * tests/testsuite.at: Add glr-regr1.at test.
6898 * tests/Makefile.am: Add glr-regr1.at test.
6900 2002-10-24 Paul Eggert <eggert@twinsun.com>
6904 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6905 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6906 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6907 Don't assume strdup exists; POSIX says its an XSI extension.
6908 Check for buffer overflow on input.
6910 2002-10-24 Akim Demaille <akim@epita.fr>
6912 * src/output.c (output_skeleton): Don't disable M4sugar comments
6913 too soon: it results in comments being expanded.
6914 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6917 2002-10-24 Akim Demaille <akim@epita.fr>
6919 * data/yacc.c (m4_int_type): New.
6920 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6921 char' as only yacc.c wants K&R portability.

6923 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
6924 Reported by Quoc Peyrot.
6926 2002-10-23 Paul Eggert <eggert@twinsun.com>
6928 * src/main.c (main): With --trace=time, report times even if a
6929 non-fatal error occurs. Formerly, the times were reported in some
6930 such cases but not in others.
6931 * src/reader.c (reader): Just return if a complaint has been issued,
6932 instead of exiting, so that 'main' can report times.
6934 2002-10-22 Akim Demaille <akim@epita.fr>
6936 * src/system.h: Include sys/types.
6937 Reported by Bert Deknuydt.
6939 2002-10-23 Paul Eggert <eggert@twinsun.com>
6941 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
6942 Suggested by Art Haas.
6944 2002-10-22 Paul Eggert <eggert@twinsun.com>
6946 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6947 decl; not needed any more.
6948 * src/main.c (main): Use return to exit, undoing yesterday's change.
6949 The last OS that we could find where this wouldn't work is
6950 SunOS 3.5, and that's too old to worry about now.
6952 * data/glr.c (struct yyltype): Define members even when not
6953 doing locations. This is more consistent with yacc.c, and it
6954 works around the following bug reports:
6955 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6956 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6958 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6959 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6960 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6962 2002-10-22 Akim Demaille <akim@epita.fr>
6966 2002-10-21 Paul Eggert <eggert@twinsun.com>
6968 Be consistent about 'bool'; the old code used an enum in one
6969 module and an int in another, and this violates the C standard.
6970 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6971 * configure.ac (AC_HEADER_STDBOOL): Add.
6972 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
6973 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
6974 * src/symtab.c (hash_compare_symbol_t): Likewise.
6975 * src/system.h (bool, false, true): Use a definition consistent
6976 with ../lib/hash.c. All uses changed.
6978 * src/complain.c (warning_issued): Renamed from warn_message_count,
6979 so that we needn't worry about integer overflow (!).
6980 Now of type bool. All uses changed.
6981 (complaint_issued): Renamed from complain_message_count; likewise.
6983 * src/main.c (main): Use exit to exit with failure.
6985 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6986 rather than 1 and 0.
6987 * src/main.c (main): Likewise.
6988 * src/getargs.c (getargs): Likewise.
6989 * src/reader.c (reader): Likewise.
6991 * src/getarg.c (getargs): Remove duplicate code for
6992 "Try `bison --help'".
6994 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6995 What was that "2" for?
6997 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6998 * src/getargs.c (usage): Likewise.
7000 * src/getargs.c (getargs): When there are too few operands, report
7001 the last one. When there are too many, report the first extra
7002 one. This is how diffutils does it.
7004 2002-10-20 Paul Eggert <eggert@twinsun.com>
7006 Remove K&R vestiges.
7007 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
7008 * src/complain.c (VA_START): Remove. Assume prototypes.
7009 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
7010 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
7011 fatal): Assume prototypes.
7012 * src/complain.h: Assume prototypes.
7013 * src/system.h (PARAMS): Remove.
7014 Include <limits.h> unconditionally, since it's guaranteeed even
7015 for a freestanding C89 compiler.
7016 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
7017 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
7019 2002-10-20 Akim Demaille <akim@epita.fr>
7021 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
7022 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
7023 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
7024 (yyresolveStates, yyresolveAction, yyresolveStack)
7025 (yyprocessOneStack): Use them.
7026 (yy_reduce_print): New.
7027 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
7029 2002-10-20 Akim Demaille <akim@epita.fr>
7031 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
7032 arguments and output `void'.

7035 (b4_c_function_decl, b4_c_ansi_function_def)
7036 (b4_c_ansi_function_decl): New.
7037 Change the interpretation of the arguments: before `int, foo', now
7039 * data/yacc.c (yyparse): Prototype and define thanks to these.
7040 Adjust b4_c_function_def uses.
7041 * data/glr.c (yyparse): Likewise, but ANSI only.
7043 2002-10-20 Akim Demaille <akim@epita.fr>
7045 * src/output.c (prepare): Move the definition of `tokens_number',
7046 `nterms_number', `undef_token_number', `user_token_number_max'
7048 (prepare_tokens): Here.

7078 2002-10-19 Paul Eggert <eggert@twinsun.com>
7080 Do not create a temporary file, as that involves security and
7081 cleanup headaches. Instead, use a pair of pipes.
7082 Derived from a suggestion by Florian Krohm.
7083 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
7084 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
7085 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
7086 (BISON_PREREQ_SUBPIPE): Add.
7087 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

7091 * src/output.c: Include "subpipe.h".
7092 (m4_invoke): Remove decl.
7093 (scan_skel): New decl.
7094 (output_skeleton): Use pipe rather than temporary file for m4 input.
7095 Check that m4sugar.m4 is readable, to avoid deadlock.
7096 Check for pipe I/O error.
7097 * src/scan-skel.l (readpipe): Remove decl.
7098 (scan_skel): New function, to be used in place of m4_invoke.
7099 Read from stream rather than file.
7101 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
7102 float, as this generates a warning on Solaris 8 + GCC 3.2 with
7103 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
7104 this generates a more-accurate value anyway.
7106 * lib/timevar.c (timervar_accumulate): Rename locals to
7107 avoid confusion with similarly-named more-global.
7108 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
7110 * src/output.c (prepare): Use xstrdup to convert char const *
7111 to char *, to avoid GCC warning.
7113 2002-10-19 Akim Demaille <akim@epita.fr>
7115 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
7116 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
7117 Use them to have `calc.y' ready for %pure-parser.
7118 * data/yacc.c (YYLEX): Pass a yylex return type to
7121 2002-10-19 Akim Demaille <akim@epita.fr>
7123 Prototype support of %lex-param and %parse-param.
7125 * src/parse-gram.y: Add the definition of the %lex-param and
7126 %parse-param tokens, plus their rules.
7127 Drop the `_' version of %glr-parser.
7129 * src/scan-gram.l (INITIAL): Scan them.
7130 * src/muscle_tab.c: Comment changes.
7131 (muscle_insert, muscle_find): Rename `pair' as `probe'.
7132 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
7133 (muscle_entry_s): The `value' member is no longer const.
7134 Adjust all dependencies.
7135 * src/muscle_tab.c (muscle_init): Adjust: use
7136 MUSCLE_INSERT_STRING.
7137 Initialize the obstack earlier.
7138 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
7139 (muscle_pair_list_grow): New.
7140 * data/c.m4 (b4_c_function_call, b4_c_args): New.

7145 2002-10-19 Akim Demaille <akim@epita.fr>
7147 * src/getargs.c (usage): Take status as argument and exit
7149 Report the traditional `Try ... --help' message when status != 0.
7150 (usage, version): Don't take a FILE * as arg, it is pointless.
7151 (getargs): When there is an incorrect number of arguments, make it
7152 an error, and report it GNUlically thanks to `usage ()'.
7154 2002-10-18 Paul Eggert <eggert@twinsun.com>
7156 * data/glr.c (yyreportParseError): Don't assume that sprintf
7157 yields the length of the printed string, as this is not true
7158 on SunOS 4.1.4. Reported by Peter Klein.
7160 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
7161 * tests/conflicts.at (%nonassoc and eof): Likewise.
7162 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
7164 2002-10-17 Akim Demaille <akim@epita.fr>
7166 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
7167 * src/getargs.c (trace_types, trace_args): Adjust.
7168 * src/reader.c (grammar_current_rule_prec_set)
7169 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
7170 Standardize error messages.
7172 (reader): Use trace_flag to enable scanner/parser debugging,
7173 instead of an adhoc scheme.
7174 * src/scan-gram.l: Remove trailing debugging code.
7176 2002-10-16 Paul Eggert <eggert@twinsun.com>
7178 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
7181 * NEWS: Officially drop support for building Bison with K&R C,
7182 since it didn't work anyway and it's not worth worrying about.
7183 * Makefile.maint (wget_files): Remove ansi2knr.c.
7184 (ansi2knr.c-url_prefix): Remove.
7185 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
7186 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
7187 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
7189 2002-10-15 Paul Eggert <eggert@twinsun.com>
7191 Stop using the "enum_" trick for K&R-style function definitions;
7192 it confused me, and I was the author! Instead, assume that people
7193 who want to use K&R C compilers (when using these modules in GCC,
7194 perhaps?) will run ansi2knr.
7196 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
7197 All uses of "enum_" changed to "enum ".
7198 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

7209 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
7210 Use function prototypes; this removes the need for declaring
7211 static functions simply to provide their prototypes.
7212 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

7278 2002-10-14 Akim Demaille <akim@epita.fr>
7280 * src/tables.c (table_ninf_remap): base -> tab.
7281 Reported by Matt Rosing.
7283 2002-10-14 Paul Eggert <eggert@twinsun.com>

7286 tests/cxx-type.at, tests/headers.at, tests/input.at,
7287 tests/regression.at, tests/synclines.at, tests/torture.at:
7288 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
7289 so that the tests still work even if POSIXLY_CORRECT is set.
7290 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
7292 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
7293 for portability to K&R hosts. Fix typo: signed char is guaranteed
7294 only to 127, not to 128.
7295 * data/glr.c (yysigned_char): New type.
7296 * data/yacc.c (yysigned_char): Likewise.
7297 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
7299 2002-10-13 Paul Eggert <eggert@twinsun.com>
7301 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
7302 true due to limited range of data type" warning from GCC.
7304 * data/c.m4 (b4_token_defines): Protect against double-inclusion
7305 by wrapping enum yytokentype's definition inside #ifndef
7306 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
7308 2002-10-13 Akim Demaille <akim@epita.fr>
7310 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
7311 Un yy- yyrhs to avoid the name clash with the global YYRHS.
7313 2002-10-13 Akim Demaille <akim@epita.fr>
7315 * Makefile.maint: Update from Autoconf 2.54.
7316 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
7318 2002-10-13 Akim Demaille <akim@epita.fr>
7320 * src/print.c (print_state): Separate the list of solved conflicts
7321 from the other items.

7326 Let nondeterministic skeletons be usable with deterministic
7329 With the patch, GAWK compiled by GCC without -O2 passes its test
7330 suite using a GLR parser driven by LALR tables. It fails with -O2
7331 because `struct stat' gives two different answers on my machine:
7332 88 (definition of an auto var) and later 96 (memset on this var).
7333 Hence the stack is badly corrumpted. The headers inclusion is to
7334 blame: if I move the awk.h inclusion before GLR's system header
7335 inclusion, the two struct stat have the same size.
7337 * src/tables.c (pack_table): Always create conflict_table.
7338 (token_actions): Always create conflict_list.
7339 * data/glr.c (YYFLAG): Remove, unused.
7341 2002-10-13 Akim Demaille <akim@epita.fr>
7343 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
7345 (VALGRIND, GXX): New.
7346 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
7347 * tests/bison.in: Run $PREBISON a pre-command.
7348 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
7349 (maintainer-check-g++): New.
7350 * Makefile.am (maintainer-check): New.
7352 2002-10-13 Akim Demaille <akim@epita.fr>
7354 * data/glr.c: Formatting changes.
7355 Tweak some trace messages to match yacc.c's.
7357 2002-10-13 Akim Demaille <akim@epita.fr>
7359 GLR parsers sometimes raise parse errors instead of performing the
7361 Reported by Charles-Henry de Boysson.
7363 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
7364 check the length of the traces when %glr.
7365 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
7367 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
7369 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
7370 (yyltype): Remove the yy prefix from the member names.
7371 (yytable): Complete its comment.
7372 (yygetLRActions): Map error action number from YYTABLE from
7374 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
7375 (which was a bug: it should have been YYTABEL_NINF, and yet it was
7376 not satisfying as we could compare an YYACTION computed from
7377 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
7378 only value for error actions.
7379 (yyreportParseError): In verbose parse error messages, don't issue
7380 `error' in the list of expected tokens.
7381 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
7382 next action to perform to match glr.c's decoding.
7383 (yytable): Complete its comment.
7385 2002-10-13 Paul Eggert <eggert@twinsun.com>
7387 Fix problem reported by Henrik Grubbstroem in
7388 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
7389 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
7390 because the Bison parser reads the second action before reducing
7392 * src/scan-gram.l (rule_length): New static var.
7393 Use it to keep track of the rule length in the scanner, since
7394 we can't expect the parser to be in lock-step sync with the scanner.
7395 (handle_action_dollar, handle_action_at): Use this var.
7396 * tests/actions.at (Exotic Dollars): Test for the problem.
7398 2002-10-12 Paul Eggert <eggert@twinsun.com>
7400 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
7401 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
7402 Include <sys/time.h> when checking for clock_t and struct tms.
7403 Use same include order as source.
7404 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
7405 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
7407 * lib/timevar.c: Update copyright date and clarify comments.
7408 (get_time) [IN_GCC]: Keep the GCC version for reference.
7410 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
7411 GCC version as of today, then merge Bison's changes.
7412 Change "GCC" to "Bison" in copyright notice. timevar.def's
7413 author is Akim, so change that too.
7415 * src/reader.c (grammar_current_rule_check):
7416 Don't worry about the default action if $$ is untyped.
7417 Prevents bogus warnings reported by Jim Gifford in
7418 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
7420 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
7421 * data/glr.c, data/lalr1.cc, data/yacc.c:
7422 Output token definitions before the first part of user declarations.
7423 Fixes compatibility problem reported by Jim Gifford for kbd in
7424 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
7426 2002-10-11 Paul Eggert <eggert@twinsun.com>
7428 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
7429 (yyparse): here. This undoes some of the 2002-07-25 change.
7430 Compatibility problem reported by Ralf S. Engelschall with
7431 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

7446 Portability fixes for bitsets; this also avoids several GCC
7449 * lib/abitset.c: Include <stddef.h>, for offsetof.
7450 * lib/lbitset.c: Likewise.
7452 * lib/abitset.c (abitset_bytes): Return a size that is aligned
7453 properly for vectors of objects. Do not assume that adding a
7454 header size to a multiple of a word size yields a value that is
7455 properly aligned for the whole union.
7456 * lib/bitsetv.c (bitsetv_alloc): Likewise.

7549 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
7550 which was inadvertently undone by the 2002-09-30 patch.

7927 exit status as failure, not just exit status 1. Sun C exits

7972 (lalr_free): Adjust.
7973 * src/main.c (main): Don't free nullable and derives too early: it
7974 is used by --verbose.
7975 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
7977 2002-08-01 Akim Demaille <akim@epita.fr>

8095 different: save its reduction (accept) instead of having a state

8152 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
8153 for the time being: %locations ought to provide it to yyerror.

8157 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

10132 * data/bison.c++, data/bison.simple: Don't output the current file
10133 name in #line, to avoid useless diffs between two identical

10435 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
10436 Treat C++ just like Standard C instead of trying to support
10437 namespace cleanliness.
10439 2002-02-14 Akim Demaille <akim@epita.fr>
10441 * tests/regression.at (else): Adjust to Andreas' change.
10443 2002-02-14 Akim Demaille <akim@epita.fr>
10445 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
10447 2002-02-13 Andreas Schwab <schwab@suse.de>
10449 * src/output.c (output_rule_data): Don't output NULL, it might
10450 not be defined yet.
10452 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
10454 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
10455 (Copyright notice): Update.
10457 2002-02-11 Akim Demaille <akim@epita.fr>
10459 * tests/regression.at (%nonassoc and eof): Don't include
10460 nonportable headers.
10462 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
10464 * data/bison.c++: Correct error recovery. Make the user able to
10465 initialize the starting location.
10467 2002-02-07 Akim Demaille <akim@epita.fr>
10469 * tests/input.at: New.
10471 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10473 * data/bison.c++: Replace some direct m4 expansions by constants. Be
10474 more consistent when naming methods and variables. Put preprocessor
10475 directives around tables only needed for debugging.
10477 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10479 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
10481 (yy::b4_name::parse): Use print_.
10483 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10485 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
10487 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10489 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
10491 (yy::b4_name::parse): Build verbose error messages, and use error_.
10493 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10495 * data/bison.c++: Fix m4 quoting in comments.
10497 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10499 * data/bison.c++: Adjust the parser code. Fix some muscles that were
10500 not expanded by m4.
10502 2002-02-05 Akim Demaille <akim@epita.fr>
10504 * data/bison.c++: Adjust to the M4 back end.
10505 More is certainly needed.
10507 2002-02-05 Akim Demaille <akim@epita.fr>
10509 Give a try to M4 as a back end.
10511 * lib/readpipe.c: New, from wdiff.
10512 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
10514 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
10515 specific values. Now it is m4 that performs the lookup.
10516 * src/parse-skel.y: Remove.
10517 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
10518 * src/output.c (actions_output, guards_output)
10519 (token_definitions_output): No longer keeps track of the output
10520 line number, hence remove the second argument.
10521 (guards_output): Check against the guard member of a rule, not the
10524 (output_skeleton): Don't look for the skeleton location, let m4 do
10526 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
10528 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
10529 (prepare): Given that for the time being changesyntax is not
10530 usable in M4, rename the muscles using `-' to `_'.
10531 Define `defines_flag', `output_parser_name' and `output_header_name'.
10532 * src/output.h (actions_output, guards_output)
10533 (token_definitions_output): Adjust prototypes.
10534 * src/scan-skel.l: Instead of scanning the skeletons, it now
10535 processes the output of m4: `__oline__' and `#output'.
10536 * data/bison.simple: Adjust to be used by M4(sugar).
10537 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
10539 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
10540 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
10541 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
10542 shamelessly stolen from CVS Autoconf.
10544 2002-02-05 Akim Demaille <akim@epita.fr>
10546 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
10547 * configure.in: Check for the declarations of free and malloc.
10548 * src/muscle_tab.c: Adjust.
10550 2002-02-05 Akim Demaille <akim@epita.fr>
10552 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
10553 which have no values.
10555 2002-02-05 Akim Demaille <akim@epita.fr>
10557 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
10560 2002-01-29 Paul Eggert <eggert@twinsun.com>
10562 * src/bison.simple (YYSIZE_T): Do not define merely because
10563 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
10564 On some platforms, <alloca.h> does not declare YYSTD (size_t).
10566 2002-01-27 Akim Demaille <akim@epita.fr>
10568 Fix `%nonassoc and eof'.
10570 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
10571 which were not properly copied! Replace
10572 memcpy (res->errs, src->errs, src->nerrs);
10574 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
10576 * tests/regression.at (%nonassoc and eof): Adjust to newest
10577 Autotest: `.' is not in the PATH.
10579 2002-01-27 Akim Demaille <akim@epita.fr>
10581 * tests/sets.at (AT_EXTRACT_SETS): New.
10582 (Nullable): Use it.
10585 2002-01-26 Akim Demaille <akim@epita.fr>
10587 * tests/actions.at, tests/calc.at, tests/headers.at,
10588 * tests/torture.at: Adjust to the newest Autotest which no longer
10589 forces `.' in the PATH.
10591 2002-01-25 Akim Demaille <akim@epita.fr>
10593 * tests/regression.at (%nonassoc and eof): New.
10594 Suggested by Robert Anisko.
10596 2002-01-24 Akim Demaille <akim@epita.fr>
10598 Bison dumps core when trying to complain about broken input files.
10599 Reported by Cris van Pelt.
10601 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
10602 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
10604 (Invalid inputs): Strengthen: exercise parse_percent_token.
10606 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
10608 * src/Makefile.am: Add bison.c++.
10609 * src/bison.c++: New skeleton.
10611 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
10615 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
10617 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
10619 2002-01-20 Marc Autret <marc@gnu.org>
10621 * src/files.c (compute_output_file_names): Fix
10623 2002-01-20 Marc Autret <marc@gnu.org>
10625 * tests/output.at: New test.
10626 * src/files.c (compute_base_names): Don't map extensions when
10627 the YACC flag is set, use defaults.
10628 Reported by Evgeny Stambulchik.
10630 2002-01-20 Marc Autret <marc@gnu.org>
10632 * src/system.h: Need to define __attribute__ away for non-GCC
10633 compilers as well (i.e., the vendor C compiler).
10634 Suggested by Albert Chin-A-Young.
10636 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
10638 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
10639 canonical definition.
10640 * src/system.h: Use the canonical definition for PARAMS (avoids
10641 a conflict with the macro from lib/hash.h).
10643 2002-01-11 Akim Demaille <akim@epita.fr>
10645 * configure.in: Use AC_FUNC_STRNLEN.
10646 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
10648 2002-01-09 Akim Demaille <akim@epita.fr>
10650 * src/files.c, src/files.h (output_infix): New.
10651 (tab_extension): Remove.
10652 (compute_base_names): Compute the former, drop the latter.
10653 * src/output.c (prepare): Insert the muscles `output-infix', and
10655 * src/parse-skel.y (string, string.1): New.
10656 (section.header): Use it.
10657 (section.yacc): Remove.
10658 (prefix): Remove too.
10659 * src/scan-skel.l: Adjust.
10660 * src/bison.simple, src/bison.hairy: Adjust.
10662 2002-01-09 Akim Demaille <akim@epita.fr>
10664 * configure.in (WERROR_CFLAGS): Compute it.
10665 * src/Makefile.am (CFLAGS): Pass it.
10666 * tests/atlocal.in (CFLAGS): Idem.
10667 * src/files.c: Fix a few warnings.
10668 (get_extension_index): Remove, unused.
10670 2002-01-08 Akim Demaille <akim@epita.fr>
10672 * src/getargs.c (AS_FILE_NAME): New.
10673 (getargs): Use it to convert DOSish file names.
10674 * src/files.c (base_name): Rename as full_base_name to avoid
10675 clashes with `base_name ()'.
10676 (filename_split): New.
10677 (compute_base_names): N-th rewrite, using filename_split.
10679 2002-01-08 Akim Demaille <akim@epita.fr>
10681 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10682 New, stolen from the Fileutils 4.1.
10683 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10684 * configure.in: Check for the presence of memrchr, and of its
10687 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10689 * lib/hash.h (__P): Added definition for this macro.
10690 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10691 BUILT_SOURCES, to ensure they are generated first.
10692 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10693 %error-verbose to allow bootstrapping with bison 1.30x.
10695 2002-01-06 Akim Demaille <akim@epita.fr>
10697 * src/reader.c (parse_braces): Don't fetch the next char, the
10698 convention is to fetch on entry.
10699 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10700 'switch' without a following semicolon.
10701 * tests/regression.at (braces parsing): New.
10703 2002-01-06 Akim Demaille <akim@epita.fr>
10705 Bison is dead wrong in its RR conflict reports.
10707 * tests/torture.at (GNU Cim Grammar): New.
10708 * src/conflicts.c (count_rr_conflicts): Fix.
10710 2002-01-06 Akim Demaille <akim@epita.fr>
10712 Creating package.m4 from configure.ac causes too many problems.
10714 * tests/Makefile.am (package.m4): Create it by hand,
10715 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10717 2002-01-06 Akim Demaille <akim@epita.fr>
10719 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10722 2002-01-04 Paul Eggert <eggert@twinsun.com>
10724 * doc/bison.texinfo (Debugging):
10725 Remove YYSTDERR; it's no longer defined or used.
10726 Also, s/cstdio.h/cstdio/.
10728 2002-01-03 Akim Demaille <akim@epita.fr>
10730 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10732 2002-01-03 Akim Demaille <akim@epita.fr>
10734 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10735 tracing code to --trace, wait for a better --trace option, with
10738 2002-01-03 Akim Demaille <akim@epita.fr>
10740 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10741 The ISO C++ standard is extremely clear about it: stderr is
10742 considered a macro, not a regular symbol (see table 94 `Header
10743 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10744 Therefore std:: does not apply to it. It still does with fprintf.
10745 Also, s/cstdio.h/cstdio/.
10747 2002-01-03 Akim Demaille <akim@epita.fr>
10749 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10750 for non system headers.
10752 2002-01-02 Akim Demaille <akim@epita.fr>
10754 Equip the skeleton chain with location tracking, runtime trace,
10755 pure parser and scanner.
10757 * src/parse-skel.y: Request a pure parser, locations, and prefix
10759 (%union): Having several members with the same type does not help
10760 type mismatches, simplify.
10761 (YYPRINT, yyprint): New.
10762 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10763 (skel_error): this.
10765 * src/scan-skel.l: Adjust to these changes.
10766 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10767 (LOCATION_PRINT, skel_control_t): New.
10769 2001-12-30 Akim Demaille <akim@epita.fr>
10771 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10772 replace `gb' with BLANKS.
10773 * src/scan-skel.l: Adjust.
10775 2001-12-30 Akim Demaille <akim@epita.fr>
10777 * src/system.h: We don't need nor want bcopy.
10778 Throw away MS-DOS crap: we don't need getpid.
10779 * configure.in: We don't need strndup. It was even causing
10780 problems: because Flex includes the headers *before* us,
10781 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10783 * lib/xstrndup.c: New.
10784 * src/scan-skel.l: Use it.
10785 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10786 * src/parse-skel.y: Use %directives instead of #defines.
10788 2001-12-30 Akim Demaille <akim@epita.fr>
10790 * src/skeleton.h: New.
10791 * src/output.c (output_parser, output_master_parser): Remove, dead
10793 * src/output.h (get_lines_number, actions_output, guards_output)
10794 (token_definitions_output): Prototype them.
10795 * src/parse-skel.y: Add the license notice.
10796 Include output.h and skeleton.h.
10797 (process_skeleton): Returns void, and takes a single parameter.
10798 * src/scan-skel.l: Add the license notice.
10799 Include skeleton.h.
10800 Don't use %option yylineno: it seems that then Flex imagines
10801 REJECT has been used, and therefore it won't reallocate its
10802 buffers (which makes no other sense to me than a bug). It results
10803 in warnings for `unused: yy_flex_realloc'.
10805 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10807 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10808 (MUSCLE_INSERT_PREFIX): ...to there.
10809 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10810 (MUSCLE_INSERT_PREFIX): Move from here...
10812 * src/bison.hairy: Add a section directive. Put braces around muscle
10813 names. This parser skeleton is still broken, but Bison should not
10814 choke on a bad muscle 'syntax'.
10815 * src/bison.simple: Add a section directive. Put braces around muscle
10818 * src/files.h (strsuffix, stringappend): Add declarations.
10819 (tab_extension): Add declaration.
10820 (short_base_name): Add declaration.
10822 * src/files.c (strsuffix, stringappend): No longer static. These
10823 functions are used in the skeleton parser.
10824 (tab_extension): New.
10825 (compute_base_names): Use the computations done in this function
10826 to guess if the generated parsers should have '.tab' in their
10828 (short_base_name): No longer static.
10830 * src/output.c (output_skeleton): New.
10831 (output): Disable call to output_master_parser, and give a try to
10832 a new skeleton handling system.
10833 (guards_output, actions_output): No longer static.
10834 (token_definitions_output, get_lines_number): No longer static.
10836 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
10838 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
10841 * src/parse-skel.y: New file.
10842 * src/scan-skel.l: New file.
10844 2001-12-29 Akim Demaille <akim@epita.fr>
10846 %name-prefix is broken.
10848 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10849 Adjust all dependencies.
10850 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10853 Renaming yylval but not yylloc is not consistent. Now we do.
10855 * src/bison.simple: Prefix yylloc if used.
10856 * doc/bison.texinfo (Decl Summary): Document that.
10858 2001-12-29 Akim Demaille <akim@epita.fr>
10860 * doc/bison.texinfo: Promote `%long-directive' over
10862 Remove all references to fixed-output-files, yacc is enough.
10864 2001-12-29 Akim Demaille <akim@epita.fr>
10866 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10867 user prologue. These are defaults.
10868 * tests/actions.at (Mid-rule actions): Make sure the user can
10869 define YYDEBUG and YYERROR_VERBOSE.
10871 2001-12-29 Akim Demaille <akim@epita.fr>
10873 * src/output.c (header_output): Don't forget to export YYLTYPE and
10875 * tests/headers.at (export YYLTYPE): New, make sure it does.
10876 * tests/regression.at (%union and --defines, Invalid CPP headers):
10878 * tests/headers.at: here.
10880 2001-12-29 Akim Demaille <akim@epita.fr>
10882 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
10884 2001-12-29 Akim Demaille <akim@epita.fr>
10886 * tests/actions.at (Mid-rule actions): Output on a single line
10887 instead of several.
10889 2001-12-29 Akim Demaille <akim@epita.fr>
10891 * doc/bison.texinfo: Formatting changes.
10893 2001-12-29 Akim Demaille <akim@epita.fr>
10895 Don't store the token defs in a muscle, just be ready to output it
10896 on command. Now possible via `symbols'. Fixes a memory leak.
10898 * src/output.c (token_definitions_output): New.
10899 (output_parser, header_output): Use it.
10900 * src/reader.c (symbols_save): Remove.
10902 2001-12-29 Akim Demaille <akim@epita.fr>
10904 * src/bison.simple: Do not provide a default for YYSTYPE and
10905 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10908 2001-12-29 Akim Demaille <akim@epita.fr>
10910 Mid-rule actions are simply... ignored!
10912 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10913 the empty-rule associated to the dummy symbol, not to the host
10915 * tests/actions.at (Mid-rule actions): New.
10917 2001-12-29 Akim Demaille <akim@epita.fr>
10921 * src/reader.c (reader): Free grammar.
10923 2001-12-29 Akim Demaille <akim@epita.fr>
10927 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10928 since it allocates it for each state, although only one is needed.
10929 (allocate_storage): Do it here.
10931 2001-12-29 Akim Demaille <akim@epita.fr>
10933 * src/options.h, src/options.c (create_long_option_table): Rename
10935 (long_option_table_new): this, with a clearer prototype.
10936 (percent_table): Remove, unused,
10937 * src/getargs.c (getargs): Adjust.
10939 2001-12-29 Akim Demaille <akim@epita.fr>
10941 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
10942 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
10945 2001-12-29 Akim Demaille <akim@epita.fr>
10947 * src/lalr.c (build_relations): Rename `states' as `states1'.
10948 Sorry, I don't understand exactly what it is, no better name...
10950 2001-12-29 Akim Demaille <akim@epita.fr>
10952 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10953 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
10954 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
10957 2001-12-29 Akim Demaille <akim@epita.fr>
10959 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
10962 2001-12-29 Akim Demaille <akim@epita.fr>
10964 * src/reader.c, src/reader.h (user_toknums): Remove.
10965 Adjust all users to use symbols[i]->user_token_number.
10967 2001-12-29 Akim Demaille <akim@epita.fr>
10969 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
10970 Adjust all users to use symbols[i]->prec or ->assoc.
10972 2001-12-29 Akim Demaille <akim@epita.fr>
10974 * src/reader.c, src/reader.h (tags): Remove.
10975 Adjust all users to use symbols[i]->tag.
10977 2001-12-29 Akim Demaille <akim@epita.fr>
10979 * src/gram.h, src/gram.c (symbols): New, similar to state_table
10981 * src/reader.c (packsymbols): Fill this table.
10983 * src/conflicts.c (resolve_sr_conflict): Adjust.
10984 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10986 Use symbols[i]->tag instead of tags[i].
10988 2001-12-29 Akim Demaille <akim@epita.fr>
10990 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10991 In addition, put a comment in there, to replace...
10992 * tests/regression.at (%union and C comments): Remove.
10994 2001-12-29 Akim Demaille <akim@epita.fr>
10996 * tests/regression.at (Web2c Actions): Blindly move the actual
10997 output as expected output. The contents *seem* right to me, but I
10998 can't pretend reading perfectly parser tables... Nonetheless, all
10999 the other tests pass correctly, the table look OK, even though the
11000 presence of `$axiom' is to be noted: AFAICS it is useless (but
11003 2001-12-29 Akim Demaille <akim@epita.fr>
11005 * src/reader.c (readgram): Don't add the rule 0 if there were no
11006 rules read. In other words, add it _after_ having performed
11007 grammar sanity checks.
11008 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
11010 2001-12-29 Akim Demaille <akim@epita.fr>
11012 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
11013 visible, and some states have now a different number.
11015 2001-12-29 Akim Demaille <akim@epita.fr>
11017 * src/reader.c (readgram): Bind the initial rule's lineno to that
11019 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
11020 (Solved SR Conflicts): Adjust rule 0's line number.
11022 2001-12-29 Akim Demaille <akim@epita.fr>
11024 Fix the `GAWK Grammar' failure.
11026 * src/LR0.c (final_state): Initialize to -1 so that we do compute
11027 the reductions of the first state which was mistakenly confused
11028 with the final state because precisely final_state was initialized
11030 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
11031 now noticed by Bison.
11032 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
11033 have a reduction on $default.
11035 2001-12-29 Akim Demaille <akim@epita.fr>
11037 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
11039 * src/closure.c (print_closure): Likewise.
11040 * src/derives.c (print_derives): Likewise.
11041 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
11044 2001-12-29 Akim Demaille <akim@epita.fr>
11046 * src/lalr.c (lookaheads_print): New.
11047 (lalr): Call it when --trace-flag.
11048 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
11051 2001-12-29 Akim Demaille <akim@epita.fr>
11053 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
11054 when walking through ritem, even via rule->rhs.
11055 * src/reduce.c (dump_grammar, useful_production, reduce_output)
11056 (useful_production, useless_nonterminals): Likewise.
11057 (reduce_grammar_tables): Likewise, plus update nritems.
11058 * src/nullable.c (set_nullable): Likewise.
11059 * src/lalr.c (build_relations): Likewise.
11060 * tests/sets.at (Nullable): Adjust.
11061 Fortunately, now, the $axiom is no longer nullable.
11063 2001-12-29 Akim Demaille <akim@epita.fr>
11065 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

11073 2001-12-29 Akim Demaille <akim@epita.fr>
11075 * src/output.c: Comment changes.
11077 2001-12-27 Paul Eggert <eggert@twinsun.com>
11079 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
11080 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
11081 Sparc, as they were causing more porting problems than the
11082 (minor) performance improvement was worth.
11084 Also, catch up with 1.31's YYSTD.
11086 2001-12-27 Akim Demaille <akim@epita.fr>
11088 * src/output.c (output_gram): Rely on nritems, not the
11089 0-sentinel. See below.
11090 Use -1 as separator, not 0.
11091 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
11092 Rely on -1 as separator in yyrhs, instead of 0.
11093 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
11094 twice `Now at end of input', therefore there are two lines less to
11097 2001-12-27 Akim Demaille <akim@epita.fr>
11099 * tests/regression.at (Unresolved SR Conflicts):
11100 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
11103 2001-12-27 Akim Demaille <akim@epita.fr>
11105 * src/LR0.c (new_state): Recognize the final state by the fact it
11106 is reached by eoftoken.
11107 (insert_start_shifting_state, insert_eof_shifting_state)
11108 (insert_accepting_state, augment_automaton): Remove, since now
11109 these states are automatically computed from the initial state.
11110 (generate_states): Adjust.
11111 * src/print.c: When reporting a rule number to the user, substract
11112 1, so that the axiom rule is rule 0, and the first user rule is 1.
11113 * src/reduce.c: Likewise.
11114 * src/print_graph.c (print_core): For the time being, just as for
11115 the report, depend upon --trace-flags to dump the full set of
11117 * src/reader.c (readgram): Once the grammar read, insert the rule
11118 0: `$axiom: START-SYMBOL $'.
11119 * tests/set.at: Adjust: rule 0 is now displayed, and since the
11120 number of the states has changed (the final state is no longer
11121 necessarily the last), catch up.
11123 2001-12-27 Akim Demaille <akim@epita.fr>
11125 Try to make the use of the eoftoken valid. Given that its value
11126 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
11127 is used instead of > 0 where appropriate, (ii), depend upon nritems
11128 instead of the 0-sentinel.
11130 * src/gram.h, src/gram.c (nritems): New.
11131 Expected to be duplication of nitems, but for the time being...
11132 * src/reader.c (packgram): Assert nritems and nitems are equal.
11133 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
11134 * src/closure.c (print_closure, print_fderives): Likewise.

11139 2001-12-27 Akim Demaille <akim@epita.fr>
11141 * src/main.c (main): If there are complains after grammar
11142 reductions, then output the report anyway if requested, then die.
11143 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
11144 * src/reader.c (eoftoken): New.
11145 (parse_token_decl): If the token being defined has value `0', it
11147 (packsymbols): No longer hack `tags' to insert `$' by hand.
11148 Be sure to preserve the value of the eoftoken.
11149 (reader): Make sure eoftoken is defined.
11150 Initialize nsyms to 0: now eoftoken is created just like the others.
11151 * src/print.c (print_grammar): Don't special case the eof token.
11152 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
11153 lie anyway, albeit pleasant.
11154 * tests/calc.at: Exercise error messages with eoftoken.
11155 Change the grammar so that empty input is invalid.
11156 Adjust expectations.
11157 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
11159 2001-12-27 Akim Demaille <akim@epita.fr>
11161 * configure.in: Check the protos of strchr ans strspn.
11162 Replace strchr if needed.
11163 * src/system.h: Provide the protos of strchr, strspn and memchr if
11165 * lib/strchr.c: New.
11166 * src/reader.c (symbols_save): Use strchr.
11168 2001-12-27 Akim Demaille <akim@epita.fr>
11170 * src/print.c, src/print_graph.c (escape): New.
11171 Use it to quote the TAGS outputs.
11172 * src/print_graph.c (print_state): Now errors are in red, and
11173 reductions in green.
11174 Prefer high to wide: output the state number on a line of its own.
11176 2001-12-27 Akim Demaille <akim@epita.fr>
11178 * src/state.h, src/state.c (reductions_new): New.
11179 * src/LR0.c (set_state_table): Let all the states have a
11180 `reductions', even if reduced to 0.

11201 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
11202 * src/print.c: here.
11203 (lookaheadset, shiftset): New, used as additional storage by
11205 (print_results): Adjust.
11206 (print_shifts, print_gotos, print_errs): New, extracted from...
11207 (print_actions): here.
11208 * src/print_graph.c (print_actions): Remove dead code.
11210 2001-12-27 Akim Demaille <akim@epita.fr>

11215 2001-12-27 Akim Demaille <akim@epita.fr>
11217 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
11218 (build_relations): Adjust.

11227 * src/reader.c (packgram): Catch nitems overflows.

11232 * src/output.c (output): Adjust.
11233 * src/reader.c (parse_braces): New, factoring...
11234 (copy_action, copy_guard): these two which are renamed as...
11235 (parse_action, parse_guard): these.
11236 As a voluntary consequence, using braces around guards is now
11239 2001-12-27 Akim Demaille <akim@epita.fr>
11241 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
11242 * src/reader.c (symbol_list): `guard' and `guard_line' are new
11244 (symbol_list_new): Adjust.
11245 (copy_action): action_line is the first line, not the last.
11246 (copy_guard): Just as for actions, store the `action' only, not
11247 the switch/case/break flesh.
11248 Don't parse the user action that might follow the guard, let...
11249 (readgram): do it, i.e., now, there can be an action after a
11251 In other words the guard is just explicitly optional.
11252 (packgram): Adjust.
11253 * src/output.c (guards_output): New.
11254 (output_parser): Call it when needed.
11255 (output): Also free the guard and attrs obstacks.
11256 * src/files.c, src/files.h (obstack_save): Remove.
11257 (output_files): Remove.
11258 As a result, if one needs the former `.act' file, using an
11259 appropriate skeleton which requires actions and guards is now
11261 * src/main.c (main): Adjust.
11262 * tests/semantic.at: New.
11263 * tests/regression.at: Use `input.y' as input file name.
11264 Avoid 8+3 problems by requiring input.c when the test needs the

11269 * src/reader.c (symbol_list_new): Be sure to initialize all the
11272 2001-12-27 Akim Demaille <akim@epita.fr>
11274 All the hacks using a final pseudo state are now useless.
11276 * src/LR0.c (set_state_table): state_table holds exactly nstates.
11277 * src/lalr.c (nLA): New.
11278 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
11279 instead of lookaheadsp from the pseudo state (nstate + 1).
11281 2001-12-27 Akim Demaille <akim@epita.fr>
11283 * src/output.c (action_row, token_actions): Use a state_t instead
11284 of a integer, and nlookaheads instead of the following state's

11291 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
11292 (conflicts_print, print_reductions): Use a state_t instead of an
11293 integer when referring to a state.
11294 As much as possible, depend upon nlookaheads, instead of the
11295 `lookaheadsp' member of the following state (since lookaheads of
11296 successive states are successive, the difference between state n + 1
11297 and n served as the number of lookaheads for state n).
11298 * src/lalr.c (add_lookback_edge): Likewise.
11299 * src/print.c (print_core, print_actions, print_state)
11300 (print_results): Likewise.

11310 Add plenty of `static'.
11312 2001-12-27 Akim Demaille <akim@epita.fr>
11314 * src/output.c (prepare): Drop the muscle `ntbase' which
11315 duplicates ntokens.
11316 * src/bison.simple: Formatting/comment changes.
11317 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
11318 is an undocumented synonym.
11320 2001-12-22 Akim Demaille <akim@epita.fr>
11322 * src/output.c (output_table_data): Change the prototype to use
11323 `int' for array ranges: some invocations do pass an int, not a
11325 Reported by Wayne Green.
11327 2001-12-22 Akim Demaille <akim@epita.fr>
11329 Some actions of web2c.y are improperly triggered.
11330 Reported by Mike Castle.
11332 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

11345 2001-12-18 Akim Demaille <akim@epita.fr>
11347 Some host fail on `assert (!"foo")', which expands to
11348 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
11349 Reported by Nelson Beebee.
11351 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
11352 `#define it_succeeded 0' and `assert (it_succeeded)'.
11354 2001-12-17 Marc Autret <autret_m@epita.fr>
11356 * src/bison.simple: Don't hard code the skeleton line and filename.
11357 * src/output.c (output_parser): Rename 'line' as 'output_line'.
11358 New line counter 'skeleton_line' (skeleton-line muscle).
11360 2001-12-17 Paul Eggert <eggert@twinsun.com>
11362 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
11363 YYDEBUG must be defined to a nonzero value.
11365 * src/bison.simple (yytname): Do not assume that the user defines
11366 YYDEBUG to a properly parenthesized expression.
11368 2001-12-17 Akim Demaille <akim@epita.fr>
11370 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

11379 * src/files.h, src/files.c (open_files, close_files): Remove.
11380 * src/main.c (main): Don't open/close files, nor invoke lex_free,
11382 * src/reader.c (reader): Do it.
11384 2001-12-17 Akim Demaille <akim@epita.fr>
11386 * src/conflicts.c (print_reductions): Formatting changes.
11388 2001-12-17 Akim Demaille <akim@epita.fr>

11399 * src/reader.h (muscle_obstack): Move to...

11402 2001-12-17 Akim Demaille <akim@epita.fr>
11404 * src/output.c (action_row, save_column, default_goto)

11420 2001-12-16 Marc Autret <autret_m@epita.fr>
11422 * src/output.c (actions_output): Fix. When we use %no-lines,
11423 there is one less line per action.
11425 2001-12-16 Marc Autret <autret_m@epita.fr>
11427 * src/bison.simple: Remove a useless #line directive.

11445 2001-12-15 Akim Demaille <akim@epita.fr>
11447 Make `make distcheck' work.
11449 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
11450 system.h which uses libgettext.h.
11452 2001-12-15 Akim Demaille <akim@epita.fr>
11454 * src/nullable.c (set_nullable): Useless rules must be skipped,
11455 otherwise, since we range over their symbols, we might look at a
11456 nonterminal which no longer ``exists'', i.e., it is not counted in
11457 `nvars', hence we overflow our arrays.
11459 2001-12-15 Akim Demaille <akim@epita.fr>
11461 The header can also be produced directly, without any obstack!
11464 * src/files.c, src/files.h (defines_obstack): Remove.
11465 (compute_header_macro): Global.
11466 (defines_obstack_save): Remove.
11467 * src/reader.c (parse_union_decl): No longer output to
11468 defines_obstack: its content can be found in the `stype' muscle
11470 (output_token_translations): Merge into...
11471 (symbols_output): this.
11473 (symbols_save): this.
11475 * src/output.c (header_output): New.
11478 2001-12-15 Akim Demaille <akim@epita.fr>
11480 * src/reader.c (parse_union_decl): Instead of handling two obstack
11481 simultaneously, use one to define the `stype' muscle, and use the
11482 value of the latter to fill defines_obstack.
11483 (copy_comment): Remove.
11484 (copy_comment2): Work for a single obstack.
11486 (copy_comment): this.
11488 2001-12-15 Akim Demaille <akim@epita.fr>
11490 * src/lex.c, src/lex.h (xgetc): No longer static.
11491 * src/reader.c (parse_union_decl): Revamp.
11493 2001-12-15 Akim Demaille <akim@epita.fr>
11495 Still making progress in separating Bison into (i) input, (ii)
11496 process, (iii) output: now we can directly output the parser file
11497 without using table_obstack at all.
11499 * src/files.c, src/files.h (table_obstack): Bye bye.
11500 (parser_file_name): New.
11501 * src/files.c (compute_output_file_names): Compute it.
11502 * src/output.c (actions_output, output_parser)
11503 (output_master_parser): To a file instead of an obstack.
11505 2001-12-15 Akim Demaille <akim@epita.fr>
11507 Attach actions to rules, instead of pre-outputting them to
11510 * src/gram.h (rule_t): action and action_line are new members.
11511 * src/reader.c (symbol_list): Likewise.
11512 (copy_action): Save the actions within the rule.
11513 (packgram): Save them in rule_table.
11514 * src/output.c (actions_output): New.
11515 (output_parser): Use it on `%%actions'.
11516 (output_rule_data): Don't free rule_table.
11518 (prepare): Don't save the `action' muscle.
11519 * src/bison.simple: s/%%action/%%actions/.
11521 2001-12-15 Akim Demaille <akim@epita.fr>
11523 * src/reader.c (copy_action): When --yacc, don't append a `;'
11524 to the user action: let it fail if lacking.
11525 Suggested by Arnold Robbins and Tom Tromey.
11527 2001-12-14 Akim Demaille <akim@epita.fr>
11529 * src/lex.c (literalchar): Simply return the char you decoded, non
11530 longer mess around with obstacks and int pointers.
11531 Adjust all callers.
11533 2001-12-14 Akim Demaille <akim@epita.fr>
11535 * src/lex.c (literalchar): Don't escape the special characters,
11536 just decode them, and keep them as char (before, eol was output as
11537 the 2 char string `\n' etc.).
11538 * src/output.c (output_rule_data): Use quotearg to output the
11541 2001-12-13 Paul Eggert <eggert@twinsun.com>
11543 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11544 Do not infringe on the global user namespace when using C++.
11545 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11546 All uses of `fprintf' and `stderr' changed.
11548 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11550 2001-12-13 Akim Demaille <akim@epita.fr>
11552 The computation of nullable is broken: it doesn't handle empty
11555 * tests/torture.at (GNU AWK Grammar): New.
11556 * tests/sets.at (Nullable): New.
11557 * src/nullable.c (set_nullable): Instead of blindly looping over
11558 `ritems', loop over the rules, and then over their rhs's.
11560 Work around Autotest bugs.
11562 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11563 frame, because Autotest understand lines starting with a `+' as
11564 traces from the shell. Then, they are not processed properly.
11565 Admittedly an Autotest bug, but we don't have time to wait for
11566 Autotest to catch up.
11567 * tests/regression.at (Broken Closure): Adjust to the new table
11570 * tests/sets.at: here.
11572 2001-12-13 Akim Demaille <akim@epita.fr>
11574 * src/closure.c (closure): Use nrules instead of playing tricks
11575 with BITS_PER_WORD.
11577 2001-12-13 Akim Demaille <akim@epita.fr>
11579 * src/print.c (print_actions): Output the handling of `$' as the
11580 traces do: shifting the token EOF. Before EOF was treated as a
11582 * tests/regression.at: Adjust some tests.
11583 * src/print_graph.c (print_core): Complete the set of items via
11584 closure. The next-to-final and final states are still unsatisfying,
11585 but that's to be addressed elsewhere.
11586 No longer output the rule numbers, but do output the state number.
11587 A single loop for the shifts + gotos is enough, but picked a
11588 distinct color for each.
11589 (print_graph): Initialize and finalize closure.
11591 2001-12-13 Akim Demaille <akim@epita.fr>
11593 * src/reader.c (readgram): Remove dead code, an strip useless
11595 (get_type): Remove, unused.
11597 2001-12-12 Akim Demaille <akim@epita.fr>
11599 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11600 on that of lib/error.c.
11602 2001-12-12 Akim Demaille <akim@epita.fr>
11604 Some hosts don't like `/' in includes.
11606 * src/system.h: Include libgettext.h without qualifying the path.
11607 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11610 2001-12-11 Marc Autret <autret_m@epita.fr>
11612 * src/output.c (output_parser): Remove useless muscle.
11614 2001-12-11 Marc Autret <autret_m@epita.fr>
11616 * src/bison.simple: Remove #line just before %%epilogue. It
11617 is now handled in ...
11618 * src/reader.c (read_additionnal_code): Add the output of a
11619 #line for the epilogue.
11621 2001-12-10 Marc Autret <autret_m@epita.fr>
11623 * src/reader.c (copy_definition): Re-use CPP-outed code which
11624 replace precedent remove.
11625 * src/bison.simple: Remove #line before %%prologue because
11626 %%input-line is wrong at this time.
11628 2001-12-10 Marc Autret <autret_m@epita.fr>
11630 * src/reader.c (symbols_output): Clean up.
11631 * src/output.c (output_gram, output): Clean up.
11633 2001-12-10 Akim Demaille <akim@epita.fr>
11635 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11636 * src/LR0.c (set_state_table): here.
11637 * src/lalr.c (lalr): Call it.
11639 2001-12-10 Akim Demaille <akim@epita.fr>
11641 * src/state.h (shifts): Remove the `number' member: shifts are
11642 attached to state, hence no longer need to be labelled with a
11645 2001-12-10 Akim Demaille <akim@epita.fr>
11647 Now that states have a complete set of members, the linked list of
11648 shifts is useless: just fill directly the state's shifts member.
11650 * src/state.h (shifts): Remove the `next' member.
11651 * src/LR0.c (first_state, last_state): Remove.
11652 Adjust the callers.
11653 (augment_automaton): Don't look for the shifts that must be added
11654 a shift on EOF: it is those of the state we looked for! But now,
11655 since shifts are attached, it is no longer needed to looking
11656 merely by its id: its number.
11658 2001-12-10 Akim Demaille <akim@epita.fr>
11660 * src/LR0.c (augment_automaton): Better variable locality.
11661 Remove an impossible branch: if there is a state corresponding to
11662 the start symbol being shifted, then there is shift for the start
11663 symbol from the initial state.
11665 2001-12-10 Akim Demaille <akim@epita.fr>
11667 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11668 only when appropriate: when insert_start_shifting_state' is not
11670 * tests/regression.at (Rule Line Numbers): Adjust.
11672 2001-12-10 Akim Demaille <akim@epita.fr>
11674 * src/LR0.c (augment_automaton): Now that all states have shifts,
11675 merge the two cases addition shifts to the initial state.
11677 2001-12-10 Akim Demaille <akim@epita.fr>
11679 * src/lalr.c (set_state_table): Move to...
11681 * src/lalr.c (lalr): Don't call it...
11682 * src/LR0.c (generate_states): do it.
11683 * src/LR0.h (first_state): Remove, only the table is used.
11685 2001-12-10 Akim Demaille <akim@epita.fr>
11687 * src/LR0.h (first_shift, first_reduction): Remove.
11688 * src/lalr.c: Don't use first_shift: find shifts through the
11691 2001-12-10 Akim Demaille <akim@epita.fr>
11693 * src/LR0.c: Attach shifts to states as soon as they are
11695 * src/lalr.c (set_state_table): Instead of assigning shifts to
11696 state, just assert that the mapping was properly done.
11698 2001-12-10 Akim Demaille <akim@epita.fr>
11700 * src/LR0.c (insert_start_shift): Rename as...
11701 (insert_start_shifting_state): this.
11702 (insert_eof_shifting_state, insert_accepting_state): New.
11703 (augment_automaton): Adjust.
11704 Better locality of the variables.
11705 When looking if the start_symbol is shifted from the initial
11706 state, using `while (... symbol != start_symbol ...)' sounds
11707 better than `while (... symbol < start_symbol ...)': If fail
11708 to see how the order between symbols could be relevant!
11710 2001-12-10 Akim Demaille <akim@epita.fr>
11712 * src/getargs.h: Don't declare `spec_name_prefix' and
11713 `spec_file_prefix', declared by src/files.h.
11714 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11715 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11716 * src/output.c (prepare): Adjust.
11717 * src/reader.c (symbols_output): Likewise.
11718 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11720 2001-12-10 Akim Demaille <akim@epita.fr>
11722 * src/muscle_tab.c (muscle_init): NULL is a better default than
11725 2001-12-10 Akim Demaille <akim@epita.fr>
11727 * src/reader.c (reader): Calling symbols_output once is enough.
11729 2001-12-10 Akim Demaille <akim@epita.fr>
11731 Now that states have a complete set of members, the linked list of
11732 reductions is useless: just fill directly the state's reductions
11735 * src/state.h (struct reductions): Remove member `number' and
11737 * src/LR0.c (first_reduction, last_reduction): Remove.
11738 (save_reductions): Don't link the new reductions, store them in
11740 * src/lalr.c (set_state_table): No need to attach reductions to
11741 states, it's already done.
11742 * src/output.c (output_actions): No longer free the shifts, then
11743 the reductions, then the states: free all the states and their
11746 2001-12-10 Akim Demaille <akim@epita.fr>
11748 * src/options.c (OPTN, DRTV, BOTH): New.
11749 (option_table): Use them.
11751 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11752 the job of system.h.
11753 * src/options.c: Don't include stdio.h and xalloc.h for the same
11756 2001-12-10 Akim Demaille <akim@epita.fr>
11758 * src/output.c (output, prepare): Make sure the values of the
11759 muscles `action' and `prologue' are 0-terminated.
11761 2001-12-10 Akim Demaille <akim@epita.fr>
11763 Clean up GCC warnings.
11765 * src/reader.c (copy_action): `buf' is not used.
11766 (parse_skel_decl): Be static.
11767 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11768 * src/options.h (create_long_option_table): Have a real prototype.
11769 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11770 (hash_delete_at): Return const void *.
11771 Adjust casts to preserve the const.
11773 2001-12-10 Akim Demaille <akim@epita.fr>
11775 * configure.in: Require 2.52g.
11776 M4 is not needed, but AUTOM4TE is.
11777 * m4/m4.m4: Remove.
11778 * tests/Makefile.am: Adjust.
11780 2001-12-10 Akim Demaille <akim@epita.fr>
11782 One structure for states is enough, even though theoretically
11783 there are LR(0) states and LALR(1) states.
11785 * src/lalr.h (state_t): Remove.
11786 (state_table): Be state_t **, not state_t *.
11787 * src/state.h (core, CORE_ALLOC): Rename as...
11788 (state_t, STATE_ALLOC): this.
11789 Add the LALR(1) members: shifts, reductions, errs.
11790 * src/LR0.c (state_table): Rename as...
11791 (state_hash): this, to avoid name clashes with the global
11793 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11794 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11796 2001-12-10 Akim Demaille <akim@epita.fr>
11798 Bison dumps core on bash.y.
11799 Reported by Pascal Bart.
11801 * src/warshall.c (bitmatrix_print): New.
11803 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11804 j must be the outer loop.
11805 * tests/regression.at (Broken Closure): New.
11807 2001-12-05 Akim Demaille <akim@epita.fr>
11809 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
11811 Reported by Peter Hamorsky.
11813 2001-12-05 Akim Demaille <akim@epita.fr>
11815 * src/conflicts.c (err_table): Remove.
11816 (resolve_sr_conflict): Adjust.
11817 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
11819 (state_t.reductions, state_t.shifts): this.
11821 2001-12-05 Akim Demaille <akim@epita.fr>
11823 * src/reduce.c (reduce_grammar_tables): No longer disable the
11824 removal of useless rules via CPP but via `if (0)', so that the
11825 compiler still check the code is valid.
11826 For instance, it should have noticed `rline' no longer exists: use
11827 the `line' member of rule_t.
11828 * src/gram.c (dummy, rline): Remove, unused.
11830 2001-12-05 Akim Demaille <akim@epita.fr>
11832 * src/output.c (pack_vector): Use assert, not berror.
11833 * src/main.c (berror): Remove, unused.
11835 2001-12-05 Akim Demaille <akim@epita.fr>
11837 New experimental feature: if --verbose --trace output all the
11838 items of a state, not only its kernel.
11840 * src/print.c (print_core): If `trace_flag', then invoke closure
11841 before outputting the items of the state (print_core is no longer
11842 a correct name them).
11843 (print_results): Invoke new_closure/free_closure if needed.
11845 2001-12-05 Akim Demaille <akim@epita.fr>
11847 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
11848 * src/closure.c, src/closure.h (itemsetsize): Rename as...
11849 (nitemset): for consistency with the rest of the project.
11851 2001-12-05 Akim Demaille <akim@epita.fr>
11853 * src/closure.c (print_closure): Improve.
11854 (closure): Use it for printing input and output.
11856 2001-12-05 Akim Demaille <akim@epita.fr>
11858 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11859 indexed by nonterminals.
11861 2001-12-05 Akim Demaille <akim@epita.fr>
11863 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
11865 * src/warshall.h: Remove accidental duplication of the content.
11867 2001-12-05 Akim Demaille <akim@epita.fr>

11879 2001-12-05 Akim Demaille <akim@epita.fr>
11881 * src/output.c (action_row): De-obfuscate
11882 using the good o' techniques: arrays not pointers, variable
11883 locality, BITISSET, RESETBIT etc.
11885 2001-12-05 Akim Demaille <akim@epita.fr>
11887 Pessimize the code to simplify it: from now on, all the states
11888 have a valid SHIFTS, which NSHIFTS is possibly 0.
11890 * src/LR0.c (shifts_new): Be global and move to..
11891 * src/state.c, src/state.h: here.
11892 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
11893 * src/print_graph: Adjust.
11895 2001-12-05 Akim Demaille <akim@epita.fr>
11897 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
11898 * src/conflicts.c: Use it.
11899 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11900 incorrectly ``simplified''.
11902 2001-12-05 Akim Demaille <akim@epita.fr>
11904 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11905 using the good o' techniques: arrays not pointers, variable
11906 locality, BITISSET, RESETBIT etc.
11908 2001-12-05 Akim Demaille <akim@epita.fr>
11910 * src/state.h (SHIFT_SYMBOL): New.
11911 * src/conflicts.c: Use it to deobfuscate.
11913 2001-12-05 Akim Demaille <akim@epita.fr>
11915 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
11916 (print_reductions): De-obfuscate using the good o' techniques:
11917 arrays not pointers, variable locality, BITISSET.
11919 2001-12-05 Akim Demaille <akim@epita.fr>
11921 * src/conflicts.c (print_reductions): Arrays, not pointers.
11924 2001-12-05 Akim Demaille <akim@epita.fr>
11926 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11928 2001-12-05 Akim Demaille <akim@epita.fr>

11940 2001-12-05 Akim Demaille <akim@epita.fr>
11942 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
11943 * src/lalr.c: Use them.
11945 2001-12-05 Akim Demaille <akim@epita.fr>
11947 * src/LR0.c (augment_automaton): Formatting changes.
11948 Better variable locality.

11952 * src/lalr.c (matrix_print): New.
11953 (transpose): Use it.
11954 Use arrays instead of pointers.

11959 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
11960 * src/lalr.c (build_relations): Adjust.
11962 2001-12-05 Akim Demaille <akim@epita.fr>
11964 * src/lalr.c (transpose): Free the memory allocated to the
11965 argument, as it is replaced by the results by the unique caller.
11966 (build_relations): Merely invoke transpose: it handles the memory
11968 Improve variable locality.
11969 Avoid variables used as mere abbreviations.
11970 (compute_lookaheads): Use arrays instead of pointers.
11972 2001-12-05 Akim Demaille <akim@epita.fr>
11974 * src/lalr.c (initialize_F): Improve variable locality.
11975 Avoid variables used as mere abbreviations.

11988 2001-12-05 Akim Demaille <akim@epita.fr>
11990 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11991 the handling of squeue.
11992 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11994 2001-12-05 Akim Demaille <akim@epita.fr>
11996 Because useless nonterminals are now kept alive (instead of being
11997 `destroyed'), we now sometimes examine them, and store information
11998 related to them. Hence we need to know their number, and adjust
11999 memory allocations.
12001 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
12003 * src/LR0.c (allocate_itemsets): The memory allocated to
12004 `symbol_count' was used for two different purpose: once to count
12005 the number of occurrences of each symbol, and later reassigned to
12006 `shift_symbol', containing the symbol that can be shifted from a
12008 Deobfuscate, i.e., allocate, use and free `symbol_count' here
12010 (new_itemsets): Allocate `shift_symbol' here.
12011 (allocate_itemsets): symbol_count includes useless nonterminals.
12012 Make room for them.
12013 (free_storage): Use `free', not `XFREE', for pointers that cannot
12016 2001-12-05 Akim Demaille <akim@epita.fr>

12024 * src/gram.c, src/gram.h (ritem_print): New.
12025 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
12026 (This useless function was defined only to work around VMS linkers
12027 that can't handle compilation units with variables only).
12028 * src/reduce.c (dump_grammar): Use it to trace the construction of
12031 2001-12-04 Paul Eggert <eggert@twinsun.com>
12033 * src/bison.simple (union yyalloc): Change member names
12034 to be the same as the stack names.
12035 (yyparse): yyptr is now union yyalloc *, not char *.
12036 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
12037 and may generate better code on some machines.
12038 (yystpcpy): Use prototype if __STDC__ is defined, not just
12039 if __cplusplus is defined.
12041 2001-11-30 Akim Demaille <akim@epita.fr>
12043 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
12044 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
12045 Gettext doesn't compile cleanly, and dies with -Werror.
12046 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
12047 Include WARNING_CFLAGS here.
12048 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
12049 before being defined.

12053 * lib/quotearg.h (quotearg_n, quotearg_n_style):
12054 First arg is int, not unsigned.
12055 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
12056 (SIZE_MAX, UINT_MAX): New macros.
12057 (quotearg_n_options): Abort if N is negative.
12058 Avoid overflow check on hosts where size_t is 64 bits and int
12059 is 32 bits, as overflow is impossible there.
12060 Fix off-by-one typo that caused unnecessary reallocation.
12062 2001-11-29 Paul Eggert <eggert@twinsun.com>
12064 Name space cleanup in generated parser.
12066 * doc/bison.texinfo (Bison Parser): Discuss system headers
12067 and their effect on the user name space.
12069 * src/bison.simple:
12070 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
12071 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
12072 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
12074 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
12075 on user names when possible.
12077 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
12078 Simplify test for whather <alloca.h> exists.
12080 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
12082 (<stdio.h>): Include if YYDEBUG.
12084 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
12085 ! defined (yyoverflow) && ! defined (yymemcpy).
12087 (yymemcpy, yyparse): Rename local variables as needed so that
12088 they all begin with 'yy'.
12090 (yystrlen, yystpcpy): New functions.
12092 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
12095 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
12096 instead of relying on string.h functions. Use YYSTACK_ALLOC
12097 and YYSTACK_FREE instead of malloc and free.
12099 2001-11-30 Akim Demaille <akim@epita.fr>
12101 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
12102 before their first uses.

12112 if body instead of `;' to pacify GCC's warnings.
12114 2001-11-30 Akim Demaille <akim@epita.fr>
12116 Instead of mapping the LHS of unused rules to -1, keep the LHS
12117 valid, but flag the rules as invalid.
12119 * src/gram.h (rule_t): `useful' is a new member.
12120 * src/print.c (print_grammar): Adjust.
12121 * src/derives.c (set_derives): Likewise.
12122 * src/reader.c (packgram, reduce_output): Likewise.
12123 * src/reduce.c (reduce_grammar_tables): Likewise.

12140 2001-11-30 Akim Demaille <akim@epita.fr>

12150 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
12151 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
12153 (union yyalloc): New type.
12154 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
12155 an arbitrary restriction on hosts where size_t is wider than int.
12157 (yyparse): Don't dump core if alloca or malloc fails; instead, report
12158 a parser stack overflow. Allocate just one block of memory for all
12159 three stacks, instead of allocating three blocks; this typically is
12160 faster and reduces fragmentation.
12162 Do not limit the number of items in the stack to a value that fits
12163 in 'int', as this is an arbitrary limit on hosts with 64-bit
12164 size_t and 32-bit int.
12166 2001-11-29 Marc Autret <autret_m@epita.fr>
12168 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
12169 of defining YYERROR_VERBOSE.
12170 [AT_DATA]: $4 is now out of C declarations in the prologue.
12172 2001-11-28 Marc Autret <autret_m@epita.fr>

12216 * src/closure.c (closure): `b' and `ruleno' denote the same value:
12219 2001-11-28 Akim Demaille <akim@epita.fr>
12221 * src/closure.c (closure): Instead of looping over word in array
12222 then bits in words, loop over bits in array.
12224 2001-11-28 Akim Demaille <akim@epita.fr>
12226 * src/closure.c (closure): No longer optimize the special case
12227 where all the bits of `ruleset[r]' are set to 0, to make the code

14026 (output_files): Do it here.
14027 * src/output.c (output_headers): Document the fact that this patch
14028 introduces a guaranteed SEGV for semantic parsers.

14039 * src/conflicts.c: Return a string.
14040 * src/system.h (obstack_grow_string): Rename as...
14041 (obstack_sgrow): this. Be ready to work with non literals.
14042 (obstack_fgrow4): New.
14044 2000-12-20 Akim Demaille <akim@epita.fr>
14046 * src/files.c (open_files): Fix the computation of short_base_name

14130 2000-12-19 Akim Demaille <akim@epita.fr>
14132 * src/files.c (open_files): Yipee! We no longer need all the code

14162 2000-11-17 Akim Demaille <akim@epita.fr>
14164 * lib/obstack.h: Formatting changes.
14165 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
14166 prevents type checking.
14167 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
14168 cast the value to (void *): assigning a `foo *' to a `void *'

14190 Use them to declare the variables which are global or local to
14193 2000-11-17 Akim Demaille <akim@epita.fr>
14195 * acconfig.h: Remove, no longer used.
14197 2000-11-07 Akim Demaille <akim@epita.fr>
14199 * src: s/Copyright (C)/Copyright/g.
14201 2000-11-07 Akim Demaille <akim@epita.fr>
14203 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
14205 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
14207 2000-11-07 Akim Demaille <akim@epita.fr>
14209 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

14221 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
14222 `const' their input argument (`data' or `address').
14223 Adjust the corresponding macros to include `const' in casts.
14225 2000-11-03 Akim Demaille <akim@epita.fr>
14227 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
14228 s/PFILE1/BISON_HAIRY/.
14229 Adjust dependencies.
14231 2000-11-03 Akim Demaille <akim@epita.fr>
14233 For some reason, this was not applied.
14235 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
14236 `unlink': it's no longer used.
14238 2000-11-03 Akim Demaille <akim@epita.fr>
14240 * src/files.c (skeleton_find): New function, eved out of...

14245 Don't use `atexit'.
14247 * src/files.c (obstack_save): New function.
14248 (done): Rename as...
14249 (output_files): this.
14250 Use `obstack_save'.
14251 * src/main.c (main): Don't use `atexit' to register `done', since
14252 it no longer has to remove tmp files, just call `output_files'
14253 when there are no errors.
14255 2000-11-02 Akim Demaille <akim@epita.fr>
14257 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
14258 `unlink': it's no longer used.
14259 * src/files.h: Formatting changes.
14261 2000-11-02 Akim Demaille <akim@epita.fr>
14263 Remove the last uses of mktemp and unlink/delete.
14265 * src/files.c (fdefines, ftable): Removed.
14266 (defines_ostack, table_obstack): New.
14267 Adjust dependencies of the former into uses of the latter.

14293 (action_obstack): New.
14294 Adjust all dependencies.
14296 2000-10-20 Akim Demaille <akim@epita.fr>
14298 * lib/quote.h (PARAMS): New macro. Use it.
14300 2000-10-16 Akim Demaille <akim@epita.fr>
14302 * src/output.c (output_short_or_char_table): New function.
14303 (output_short_table, output_token_translations): Use it.

14321 * src/reader.c (copy_dollar): Likewise.
14323 2000-10-16 Akim Demaille <akim@epita.fr>
14325 * src/reader.c (copy_comment2): Expect the input stream to be on
14326 the `/' which is suspected to open a comment, instead of being
14327 called after `//' or `/*' was read.
14328 (copy_comment, copy_definition, parse_union_decl, copy_action)
14329 (copy_guard): Adjust.
14331 2000-10-16 Akim Demaille <akim@epita.fr>
14333 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
14334 `read_signed_integer'.
14336 2000-10-16 Akim Demaille <akim@epita.fr>
14338 * src/reader.c (copy_dollar): New function.
14339 (copy_guard, copy_action): Use it.
14341 2000-10-16 Akim Demaille <akim@epita.fr>
14343 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
14344 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
14345 New files, from Fileutils 4.0.27.
14346 * src/main.c (printable_version): Remove.
14347 * src/lex.c, src/reader.c: Use `quote'.

14357 2000-10-04 Akim Demaille <akim@epita.fr>
14359 When a literal string is used to define two different tokens,
14360 `bison -v' segfaults.
14361 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
14363 * tests/regression.m4: New file.
14364 Include the core of the sample provided by Piotr Gackiewicz.
14365 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
14368 2000-10-04 Akim Demaille <akim@epita.fr>
14370 * src/reader.c (parse_expect_decl): Keep `count' within the size
14374 2000-10-02 Paul Eggert <eggert@twinsun.com>
14376 * bison.s1 (yyparse): Assign the default value
14377 unconditionally, to avoid a GCC warning and make the parser a
14380 2000-10-02 Akim Demaille <akim@epita.fr>
14382 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
14385 2000-10-02 Akim Demaille <akim@epita.fr>
14387 * src/derives.c, src/print.c, src/reduce.c: To ease the
14388 translation, move some `\n' out of the translated strings.
14390 2000-10-02 Akim Demaille <akim@epita.fr>
14392 The location tracking mechanism is precious for parse error
14393 messages. Nevertheless, it is enabled only when `@n' is used in
14394 the grammar, which is a different issue (you can use it in error
14395 message, but not in the grammar per se). Therefore, there should
14396 be another means to enable it.
14398 * src/getargs.c (getargs): Support `--locations'.
14399 (usage): Report it.
14400 * src/getargs.h (locationsflag): Export it.
14401 * src/lex.c (percent_table): Support `%locations'.
14402 * src/reader.c (yylsp_needed): Remove this variable, now replaced
14403 with `locationsflag'.
14404 * doc/bison.texinfo: Document `--locations' and `%locations'.
14406 * tests/calc.m4: Test it.
14408 For regularity of the names, replace each
14409 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
14410 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
14411 In addition replace each `flag' with `_flag'.
14413 2000-10-02 Akim Demaille <akim@epita.fr>
14415 Also test parse error messages, including with YYERROR_VERBOSE.
14417 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
14419 Use it to check the computations.
14420 Use it to check `nonassoc' is honored.
14421 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
14422 `--yyerror-verbose'.
14423 (_AT_CHECK_CALC): Adjust to this option.
14424 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
14426 2000-10-02 Akim Demaille <akim@epita.fr>
14428 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14429 the latter demonstrates a flaw in the handling of non debugging
14430 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14431 was used in order to simplify:
14447 unfortunately this leads to a CPP conflict when
14448 `--name-prefix=foo' is used since it produces `#define yydebug
14451 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14452 (YYDPRINTF): New macro.
14454 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
14456 Also test `--verbose', `--defines' and `--name-prefix'.
14458 2000-10-02 Akim Demaille <akim@epita.fr>
14460 Improve the readability of the produced parsers.
14462 * src/bison.s1: Formatting changes.
14463 Improve the comment related to the `$' mark.
14464 (yydefault): Don't fall through to `yyresume': `goto' there.
14465 * src/output.c (output_parser): When the `$' is met, skip the end
14467 New variable, `number_of_dollar_signs', to check there's exactly
14468 one `$' in the parser skeleton.
14470 2000-10-02 Akim Demaille <akim@epita.fr>
14472 * lib/xstrdup.c: New file, from the fileutils.
14473 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
14474 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
14475 instead of strlen + xmalloc + strcpy.
14476 * src/symtab.c (copys): Remove, use xstrdup instead.
14478 2000-10-02 Akim Demaille <akim@epita.fr>
14480 * src/gram.h (associativity): New enum type which replaces the
14481 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
14482 `right_assoc', `left_assoc' and `non_assoc'.
14483 Adjust all dependencies.
14484 * src/reader.c: Formatting changes.
14485 (LTYPESTR): Don't define it, use it as a literal in
14486 `reader_output_yylsp'.
14487 * src/symtab.h (symbol_class): New enum type which replaces the
14488 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
14489 `sunknown', `stoken and `snterm'.
14491 2000-10-02 Akim Demaille <akim@epita.fr>
14493 * src/getargs.c (fixed_outfiles): Rename as...
14494 (yaccflag): for consistency and accuracy.
14495 Adjust dependencies.
14497 2000-10-02 Akim Demaille <akim@epita.fr>
14499 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14500 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14501 difficult and introduced a lot of core dump. It turns out that
14502 Bison used an implementation of `xmalloc' based on `calloc', and
14503 at various places it does depend upon the initialization to 0. I
14504 have not tried to isolate the pertinent places, and all the former
14505 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14506 someone should address this issue.
14508 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
14509 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

14517 Various anti-`extern in *.c' changes.
14519 * src/system.h: Include `assert.h'.
14521 2000-10-02 Akim Demaille <akim@epita.fr>
14523 * src/state.h (nstates, final_state, first_state, first_shift)
14524 (first_reduction): Move their exportation from here...
14525 * src/LR0.h: to here.
14526 Adjust dependencies.
14527 * src/getargs.c (statisticsflag): New variable.
14528 Add support for `--statistics'.
14529 Adjust dependencies.
14531 Remove a lot of now useless `extern' statements in most files.
14533 2000-10-02 Akim Demaille <akim@epita.fr>
14535 * src/LR0.h: New file.
14538 2000-10-02 Akim Demaille <akim@epita.fr>

14551 (print_conflicts): this function.
14552 Adjust dependencies.
14553 * src/conflicts.h: New file.
14554 Propagate its inclusion.
14556 2000-10-02 Akim Demaille <akim@epita.fr>
