1 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4 generated source code. Problem reported by Frans Englich in
5 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
9 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
10 shell, not within 'make', so that 'make' by an ordinary builder
11 (using GNU make) does not worry about configuring gzip. This also
12 works around a bug reported independently by Keith Thompson and by
13 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
14 stderr rather than stdout, messing up the build logs.
16 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
18 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
19 to make sure that YYID will never be unused. This fixes a 'make
20 maintainer-check' failure caused by the recent changes to the 'Trivial
21 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
23 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
25 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
27 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
28 state before an empty RHS is always resolved here. Only the location
29 of that state is guaranteed to be resolved, and that's enough. This
30 fixes the remaining bug reported by Derek M. Jones in
31 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
32 * tests/glr-regression.at (Uninitialized location when reporting
33 ambiguity): Test the above case.
34 Also, the embedded comments in this test case claim it checks the case
35 of an empty RHS that has inherited the initial location. However, the
36 corresponding LHS was already resolved, so yyresolveLocations didn't
37 actually have reason to modify it. Fix this by forcing
38 nondeterministic operation at the beginning of the parse.
40 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
42 * data/c.m4 (b4_yy_symbol_print_generate):
43 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
44 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
45 of the bugs reported today by Derek M Jones in
46 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
47 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
48 defined to be a type name without parens or brackets.
49 (Location Type): Similarly for YYLTYPE.
50 * tests/regression.at (Trivial grammars): Put in a test for this
51 bug that will be caught by 'make maintainer-check' (though not,
52 alas, by 'make check' unless your compiler is picky).
54 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
57 * configure.ac (AC_INIT): Likewise.
59 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
61 * data/glr.c (yyreportTree): Make room in yystates for the state
62 preceding the RHS. This fixes the segmentation fault reported by Derek
64 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
65 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
66 to the user. Reported for yyreportTree by Derek M. Jones later in the
68 * THANKS: Add Derek M. Jones.
69 Update my email address.
70 Fix typo in Steve Murphy's name.
72 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
74 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
75 checking against YYLAST that caused the parser to miss a potential
76 alternative in its diagnostic.
77 Problem reported by Maria Jose Moron Fernandez in
78 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
79 * data/lalr1.cc (yysyntax_error_): Likewise.
80 * data/yacc.c (yysyntax_error): Likewise.
81 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
82 tokens, in case we run into an older C compiler.
83 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
84 Use them to check for the off-by-one error fixed above.
86 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
88 * tests/regression.at (Trivial grammars): New test, to catch
89 the error fixed by the above patch.
91 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
93 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
95 Reported by Steve Murphy.
97 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
99 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
100 * data/glr.cc: b4_location_flag is now b4_locations_flag.
102 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
104 Implement --trace=m4.
105 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
106 * src/output.c (output_skeleton): When set, pass -dV to m4.
108 Factor the handling of flags in m4.
109 * src/output.c (prepare): Rename the muscle names debug, defines,
110 error_verbose to debug_flag, defines_flag, error_verbose_flag.
112 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
113 Use b4_define_flag_if to define other b4_FLAG_if macros.
114 (b4_location_if): As a consequence, rename as...
115 (b4_locations_if): this, for consistency.
116 Adjust all the skeletons.
118 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
120 * etc/bench.pm: Shorten bench names.
122 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
124 * src/output.h, src/output.c (error_verbose): Move to...
125 * src/getargs.h, src/getargs.c: here.
129 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
131 * data/c.m4 (b4_copyright): Put the special exception for Bison
132 skeletons here, so we don't have to put it in each skeleton. All
133 uses changed. Suggested by Akim Demaille. Also, wrap the
134 copyright notice, in case it is longer than 80 columns. Replace
135 comma by newline after title.
137 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
139 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
140 incompatibility, not a bug. Mention that it wasn't fixed as of
143 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
145 * examples/extexi: Enforce the precedence of concatenation over
147 Reported by Tommy Nordgren.
149 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
151 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
152 with the member "token".
153 Reported by Martin Nylin.
155 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
157 * data/glr.c: Switch to Bison 2.2 special-exception language in
158 the copyright notice. Use more-regular format for titles and
160 * data/glr.cc: Likewise.
161 * data/location.cc: Likewise.
162 * data/yacc.cc: Likewise.
163 * doc/bison.texinfo (Conditions): Document this.
164 * NEWS: likewise. Upgrade version to 2.2.
166 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
168 * data/glr.cc: Remove dead code.
170 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
172 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
173 that variable and the line breaks the bootstrap. Problem reported
176 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
178 * doc/bison.texinfo (Multiple start-symbols): New.
180 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
182 * etc/README, etc/bench.pl: New.
184 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
186 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
188 Reported by Mickael Labau.
189 * tests/input.at (Torturing the Scanner): Test it.
191 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
193 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
194 Problem reported by Bob Rossi.
196 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
198 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
199 and didn't really work.
200 For the index, use @ifnotinfo, not @iftex.
201 Minor cleanups of spacing and terminology.
203 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
205 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
206 of AT_NAME_PREFIX when %name-prefix is not used.
208 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
210 Apply --prefix to C++ skeletons too: they change the namespace.
211 The test suite already exercize these cases.
212 * data/c++.m4 (b4_namespace): New.
213 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
214 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
215 * data/yacc.c, data/glr.c: Remove a useless `[]'.
216 * doc/bison.texinfo: Document it.
217 (Option Cross Key): Use @multitable in all formats. It looks
218 nicer, even in TeX outputs.
219 (Rules): Use the same code whatever the output type is.
220 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
221 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
222 * tests/calc.at: Use it, instead of hard coding `yy'.
224 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
226 * TODO: Remove dead items.
228 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
230 * doc/FAQ: Remove, merged into...
231 * doc/bison.texinfo (FAQ): this.
232 * doc/Makefile.am (EXTRA_DIST): Adjust.
234 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
236 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
238 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
239 * doc/bison.texinfo (Calc++ Scanner): Use it.
241 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
243 Fix two nits reported by twlevo, plus one more that I discovered.
245 * src/assoc.h (assoc_to_string): Give a name to the arg, as
246 this is the usual Bison style.
247 * src/location.h (location_print): Likewise.
249 * src/reader.h (token_name): Likewise.
251 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
253 Fix some nits reported by twlevo.
254 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
255 and "POSIX". Use more-modern syntax for URLs. Mention C++
256 and ask for Java. Don't hardwire OS version numbers. Add
258 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
259 * src/conflicts.c (solved_conflicts_obstack): Now static.
261 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
263 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
264 page. Say "you can use it" not "you may use it" as on the web page;
265 we're describing capabilities not granting permission.
267 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
269 * data/glr.c (yyresolveLocations): Rename local variables to avoid
270 shadowing warnings. Use usual patter for iterating through RHS.
271 * tests/glr-regression.at
272 (Uninitialized location when reporting ambiguity):
273 Modify yylex so that it uses its argument, rather than trying
274 to rely on ARGSUSED (which doesn't work for gcc with warnings).
275 const char -> char const.
277 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
278 Don't use tabs inside commands; it messes up 'ps'.
279 Problem reported by twlevo.
281 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
283 * tests/glr-regression.at (Uninitialized location when reporting
284 ambiguity): New test case.
285 * data/glr.c (yyresolveLocations): New function, which uses
287 (yyresolveValue): Invoke yyresolveLocations before reporting an
289 * doc/bison.texinfo (Default Action for Locations): Note
290 YYLLOC_DEFAULT's usage for ambiguity locations.
291 (GLR Semantic Actions): Cross-reference those notes.
293 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
295 * tests/glr-regression.at (Leaked semantic values when reporting
296 ambiguity): Remove unnecessary union and type declarations.
297 (Leaked lookahead after nondeterministic parse syntax error): New test
299 * data/glr.c (yyparse): Check for zero stacks remaining before
300 attempting to shift the lookahead so that you don't lose it.
302 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
304 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
305 * tests/glr-regression.at (Leaked semantic values when reporting
306 ambiguity): New test case.
307 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
308 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
309 now unnecessary yystackp parameter.
310 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
311 destructors can be called.
313 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
314 in existing testcases.
316 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
318 Don't leak semantic values for parent RHS when a user action cuts the
319 parser, and clean up related code a bit.
320 * tests/glr-regression.at (Leaked merged semantic value if user action
321 cuts parse): Rename to...
322 (Leaked semantic values if user action cuts parse): ... this. Add check
323 for leaked parent RHS values.
324 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
325 between an unresolved state (non-empty chain of semantic options) and
326 an incomplete one (signaled by an empty chain).
327 (yyresolveStates): Document the interface. Move all manipulation of a
328 successfully or unsuccessfully resolved yyGLRState to...
329 (yyresolveValue): ... here so that yyresolveValue always leaves a
330 yyGLRState with consistent data and thus is easier to understand.
331 Remove the yyvalp and yylocp parameters since they are always just
332 taken from the yys parameter. When reporting a discarded merged value
333 in debugging output, note that it is incompletely merged. Document the
335 (yyresolveAction): If resolving any of the RHS states fails, destroy
336 them all rather than leaking them. Thus, as long as user actions are
337 written to clean up the RHS correctly, yyresolveAction always cleans up
338 the RHS of a semantic option. Document the interface.
340 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
342 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
343 led to a segmentation fault in GNU Pascal. Problem reported
346 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
348 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
349 mid-rule action inside a nonterminal symbol in order to declare a
350 destructor for its semantic value.

356 __cplusplus && ! defined _STDLIB_H && !
357 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
358 defined free))]: Include <stdlib.h> rather than rolling our own
359 declarations of malloc and free, to avoid problems with
360 incompatible declarations (using 'throw') C++'s stdlib.h. This
361 should fix Debian bug 340012

388 More portability fixes for problems summarized by Nelson H. F. Beebe.
390 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a

399 More portability fixes for problems summarized by Nelson H. F. Beebe.
401 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
402 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
404 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
405 nodist_PROGRAMS, since we don't need to actually compile the
406 example if we're just doing a plain 'make'. This avoids bothering
407 the installer unnecessarily about problems due to weird C++

415 than #include "...", and compile with -I'.'. The old method was
416 not portable, according to Posix and the C standard, and it does
417 not work with Sun C 5.7, where previous #line directives affect
418 the working directory used in later #include "..." directives.

431 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
433 Work around portability problems summarized by Nelson H. F. Beebe in

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

448 random system header somewhere that includes the equivalent of

455 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
457 During deterministic GLR operation, user actions should be able to
458 influence the parse by changing yychar. To make this easier to fix and
459 to make glr.c easier to evolve in general, don't maintain yytoken in
460 parallel with yychar; just compute yytoken when needed.
461 * tests/glr-regression.at (Incorrect lookahead during deterministic
462 GLR): Check that setting yychar in a user action has the intended

466 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
467 yychar rather than *yytokenp to determine the current lookahead.
468 Compute yytoken locally when needed.
469 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
472 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
473 after `--report' documentation.

484 all the test at once. This makes the output easier to read in the
487 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
488 got from <http://bro-ids.org/download.html>. The bug is that
489 when two actions appeared in succession, the second one was
490 scanned before the first one was added to the grammar rule
491 as a midrule action. Bison then output the incorrect warning
492 "parse.y:905.17-906.36: warning: unused value: $3".
493 * src/parse-gram.y (BRACED_CODE, action): These are no longer
494 associated with a value.
495 (rhs): Don't invoke grammar_current_rule_action_append.
496 (action): Invoke it here instead.
497 * src/reader.c (grammar_midrule_action): Now extern.
498 (grammar_current_rule_action_append): Don't invoke
499 grammar_midrule_action; that is now the scanner's job.
500 * src/reader.h (last_string, last_braced_code_loc):
501 (grammar_midrule_action): New decls.
502 * src/scan-gram.l (last_string): Now extern, sigh.
503 (last_braced_code_loc): New extern variable.
504 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
505 rule already has an action.
506 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
507 * tests/input.at (AT_CHECK_UNUSED_VALUES):
508 Add some tests to check that the above changes fixed the bug.
510 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
512 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
513 All used changed. Check whether the symbol has a destructor,
514 not whether it is typed.

755 In the yychar entry, remove mention of the local yychar case (pure
756 parser) since this is irrelevant information when writing semantic
757 actions and since it's already discussed in `Bison Symbols' where
758 yychar is otherwise described as an external variable.
759 In the yychar entry, don't call it the `current' look-ahead since it
760 isn't when semantic actions are deferred.
761 In the yychar and yyclearin entries, add note about deferred semantic
763 Add yylloc and yylval entries discussing look-ahead usage.
764 (Look-Ahead Tokens): When discussing yychar, don't call it the

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

819 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
821 * data/glr.c (yyresolveValue): When merging semantic options, if at
822 least one user action succeeds but a later one cuts the parse, then
823 destroy the semantic value before returning rather than leaking it.
824 (yyresolveStates): If a user action cuts the parse and thus
825 yyresolveValue fails, ignore the (unset) semantic value rather than
826 corrupting the yyGLRState, and empty the semantic options list since
827 the user actions should have called all necessary destructors.
828 Simplify code with YYCHK.
829 * tests/glr-regression.at (Corrupted semantic options if user action
830 cuts parse): New test case.
831 (Undesirable destructors if user action cuts parse): New test case.

1054 for semantic values was leaked instead.

1129 sed out the final state number.
1131 Work around portability problem on Solaris 10: flex-generated
1132 files include <stdio.h> before <config.h>, which messes up
1133 because the latter defines __EXTENSIONS__. Address the problem
1134 by creating two new little files that include <config.h> first,
1135 then include the flex-generated files. Rewrite everyone else
1136 to include <config.h> first, as well.
1137 * lib/timevar.c: Always include "config.h".

1184 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
1185 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
1187 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

1211 * NEWS: Document the following change.
1212 * data/yacc.c: Say "parser skeleton" rather than "file", since
1213 it's no longer just a file.
1214 * data/glr.c: Grant a special exception for C GLR parsers, that
1215 reads like the already-existing exception for C LALR(1) parsers.

1217 * data/lalr1.cc: Likewise.

1481 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
1482 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

1509 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
1511 Use unlocked I/O for a minor performance improvement on hosts like
1512 GNU/Linux and Solaris that support unlocked I/O. The basic idea
1513 is to use the gnlib unlocked-io module, and to prefer putc and
1514 puts to printf when either will work (since the latter doesn't
1515 come in an unlocked flavor).
1516 * bootstrap (gnulib_modules): Add unlocked-io.

1535 * src/system.h: Include unlocked-io.h rather than stdio.h.
1537 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

1675 local variables whose names begin with 'yy'.
1676 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1677 Trivial changes from Joel E. Denny.
1679 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1681 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1682 don't use alloca any more.
1684 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1685 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
1686 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

1697 This works a bit better with glibc, if user code has already included

1716 (yysyntax_error): New function.
1717 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if

1719 Instead, reallocate buffers twice as big each time, so that
1720 we waste at most half the allocated memory. Start with a small
1721 (128-byte) buffer that will suffice in most cases anyway.
1722 Use yysyntax_error to do most of the work.
1724 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1725 yynerrs is the number of errors reported, not the number of

1734 2005-09-19 Akim Demaille <akim@epita.fr>
1736 Remove the traits, failed experiment.
1737 It never proved useful, and anyway because of the current
1738 definition, it was not possible to have several specialization of
1739 this traits, making it useless.
1740 * data/lalr1.cc (yy:traits): Remove.
1741 Inline its definitions in the parser class.
1743 2005-09-19 Akim Demaille <akim@epita.fr>

1766 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
1767 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
1768 is not defined. This is an awful hack, but it's enough for now.
1769 All callers changed.
1770 * tests/glr-regression-at (make_value): Args are const pointers now,
1771 to avoid GCC warning.
1772 (Duplicated user destructor for lookahead): New test. Currently
1773 skipped. It fails on my host but I'm not sure it'll always fail.
1775 2005-09-16 Akim Demaille <akim@epita.fr>
1777 * src/symtab.h (struct symbol): Declare the printer and destructor
1778 as const, to avoid accidental calls to free.

1793 2005-09-16 Akim Demaille <akim@epita.fr>
1795 * data/lalr1.cc (yylex_): Remove, inline its code.
1796 (yyreport_syntax_error_): Remove, replaced by...
1797 (yysyntax_error_): this which returns a string and leaves to the
1798 caller the call to the users' error function.
1799 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
1800 Move from members of the parser object...
1801 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

1825 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1826 do anything if $@ exists. This reverts part of the 2005-07-07
1829 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1831 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1832 contains obsolete information and isn't worth distributing as a
1833 separate file anyway.
1834 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1835 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

1842 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
1843 Suggested by twlevo@xs4all.nl.
1845 * data/glr.c (YYCHK1): Do not assume YYE is in range.

1847 Problem reported by twlevo@xs4all.nl.
1849 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1850 standards. Use "file name" or "file" or "name", depending on
1852 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1853 not to hack/foo.tab.c.
1854 (Calc++ Top Level): 2nd arg of main is not const.
1855 * data/glr.c: b4_filename -> b4_file_name.

1957 "make check" doesn't finish with "All 1 tests passed".
1959 * tests/regression.at (Token definitions): Don't rely on
1960 AT_PARSER_CHECK for data that contains backslashes. It currently
1961 uses 'echo', and 'echo' isn't portable if its argument contains
1962 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1963 that the byte '\0xff' is not printable in the C locale; it is,
1964 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1965 not printable, so use '\0x81' to test.
1967 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1968 version of GCC, since the macro is used with non-GCC compilers.
1970 Fix core dump reported by Pablo De Napoli in
1971 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1972 * tests/regression.at (Invalid inputs with {}): New test.
1973 * src/parse-gram.y (token_name): Translate type before using
1976 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1977 the user's name space. All uses changed to __attribute__
1979 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1980 Add __attribute__ ((__noreturn__)).
1982 * etc/clcommit: Remove. We weren't using it, and it failed
1983 "make maintainer-distcheck".
1984 * Makefile.maint: Merge from coreutils.
1985 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1986 (syntax-check-rules): Change list of rules as described below.
1987 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
1988 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
1989 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):

1995 (makefile-check, po-check, author_mark_check):
1996 (makefile_path_separator_check, copyright-check):
1997 Use grep -n, to make it easier to find violations.
1998 Use CVS_LIST and CVS_LIST_EXCEPT.
1999 (header_regexp, h_re): Remove.
2001 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
2002 (my-distcheck): Use more-modern GCC flags.
2003 (signatures, %.asc): Remove.
2004 (rel-files, announcement): Remove signatures.
2005 Restore old updating code, even though we don't use it, so
2006 that we're the same as coreutils.
2007 (alpha, beta, major): Depend on news-date-check.
2008 Make the upload commands.
2010 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
2011 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
2012 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
2013 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
2014 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
2015 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.

2017 * tests/sets.at: Likewise.
2019 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
2020 we comment out the Autoconf version number.
2021 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
2022 it's error-prone and "make maintainer-distcheck" rejects it.
2024 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
2025 Indent calls to "error" to pacify "make maintainer-distcheck",
2026 when the calls are not intended to be translated.
2027 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
2029 * src/Makefile.am (DEFS): Use +=, to pacify
2030 "make maintainer-distcheck".
2031 (bison_SOURCES): Add scan-skel.h.
2032 (sc_tight_scope): New rule, from coreutils.
2034 * src/files.c (src_extension, header_extension):
2035 Now static, not extern.
2036 * src/getargs.c (short_options): Likewise.
2037 * src/muscle_tab.c (muscle_table): Likewise.
2038 * src/parse-gram.y (current_class, current_type, current_prec):
2040 * src/reader.c (grammar_end, previous_rule_end): Likewise.
2041 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
2042 * src/main.c (main): Cast bindtextdomain and textdomain calls to
2043 void, to avoid warning when NLS is disabled.
2044 * src/output.c: Include scan-skel.h.
2045 (scan_skel): Remove decl, since scan-skel.h does this.
2047 Indent calls to "error" to pacify "make maintainer-distcheck".
2048 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
2049 * src/reader.h (gram_end, gram_lineno): New decls to pacify
2050 "make maintainer-distcheck".
2051 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
2052 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
2053 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
2054 (skel_lex_destroy, scan_skel): Move these decls to...
2055 * src/scan-skel.h: New file.
2056 * src/uniqstr.c (uniqstr_assert):
2057 Indent calls to "error" to pacify "make maintainer-distcheck".
2059 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
2062 * tests/torture.at: Revamp to avoid misuse of atoi that
2063 "make maintainer-distcheck" complained about.
2065 * examples/extexi (message): Don't print a message more than once,
2066 and omit line-number decoration that makes Emacs compile think
2067 that informative messages are worth worrying about.
2069 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
2071 * configure.ac: Update version number.
2073 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
2075 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
2076 autogenerated by the maintainer.
2077 * examples/calc++/.cvsignore: Add *.yy.
2079 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
2080 * lib/bitset_stats.c (bitset_stats_init): Likewise.
2081 * lib/bitsetv.c (bitsetv_alloc): Likewise.
2083 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
2085 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
2086 from maintainer-distcheck about casting the argument of 'free'.
2088 * NEWS: Mention recent yytname changes.
2089 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
2091 * bootstrap: For translations that have not yet been upgraded to
2092 the new runtime-po domain, prime the pump by extracting the
2093 relevant strings from the obsolete translations. This code can be
2094 removed once the bison-runtime domain has been translated by each
2097 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
2098 now that token names are already quoted.
2100 Fix problem reported by Anthony Heading.
2101 * data/glr.c (YYTOKEN_TABLE): New macro.
2102 (yytname): Define if YYTOKEN_TABLE.
2103 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
2104 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
2105 (YYERROR_VERBOSE): Define the same way the other skeletons do.
2106 * src/output.c (prepare_symbols): Output token_table_flag.
2108 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
2110 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
2111 again if the first call fails.
2113 * data/glr.c (yytnamerr): New function.
2114 (yyreportSyntaxError): Use it to dequote most string literals.
2115 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
2116 with other skeletons. All uses changed.
2117 (yytnameerr_): New function.
2118 (yyreport_syntax_error): Use it to dequote most string literals.
2119 * data/yacc.c (yytnamerr): New function.
2120 (yyerrlab): Use it to decode most string literals.
2121 * doc/bison.texinfo (Decl Summary, Calling Convention):
2122 Clarify quoting convention of yytname.
2123 * src/output.c (prepare_symbols): Quote all names. This undoes
2124 the 2005-04-17 change, which is now accomplished (mostly) via
2125 changes in the parsers as described above.
2126 * tests/regression.at (Token definitions, Web2c Actions):
2127 Undo most 2005-04-17 change here, too.
2129 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
2131 Fix more problems reported by twlevo@xs4all.nl.
2132 * tests/cxx-type.at: Don't pipe output of ./types through sed to
2133 remove trailing spaces. This loses the exit status of ./types,
2134 and isn't needed since ./types shouldn't be emitting trailing
2136 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
2137 as the stack isn't valid in that case.
2139 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
2140 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
2141 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
2142 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
2144 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
2145 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
2146 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
2149 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
2150 overly-picky compilers that reject 'char *foo = "bar";'.
2152 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
2153 to FILE * parameter, not to stderr. This fixes a typo introduced
2154 in the 2005-07-12 change.
2156 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
2157 warnings from GCC 4.
2159 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
2160 (yyglrShiftDefer, yysplitStack):
2161 Remove unused parameters b4_pure_formals. All uses changed.
2162 (yyglrShift): Remove unused parameters b4_user_formals.
2164 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
2166 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
2168 Destructor cleanups and regularization among the three skeletons.
2169 * NEWS: Document the behavior changes.
2170 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
2171 stack before failing, as the cleanup code will do it for us now.
2172 * data/lalr1.cc (yyerrlab): Likewise.
2173 * data/glr.c (yyparse): Pop everything off the stack before
2174 freeing it, so that destructors get called properly.
2175 * data/lalr1.cc (yyreturn): Likewise.
2176 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
2177 This is more consistent.
2178 * doc/bison.texinfo (Destructor Decl): Mention more reasons
2179 why destructors might be called. 1.875 -> 2.1.
2180 (Destructor Decl, Decl Summary, Table of Symbols):
2181 Some English-language cleanups for %destructor.
2182 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
2183 Add output line for destructor of start symbol.
2184 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
2185 because of that same extra output line.
2187 * NEWS: Document minor wording changes in diagnostics of
2188 Bison-generated parsers.
2189 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
2190 Remove unused formals. All uses changed.
2191 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
2192 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
2193 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
2194 Rename yyoverflowab to yyexhaustedlab.
2195 When memory exhaustion occurs during syntax-error reporting,
2196 report it separately rather than in a single diagnostic; this
2198 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
2199 (Memory Exhausted): Renamed from Parser Stack Overflow.
2200 Revamp wording slightly to prefer "memory exhaustion".
2201 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
2203 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
2205 Add i18n support to the GLR skeleton. Partially fix the C++
2206 skeleton; a C++ expert needs to finish this. Remove debugging
2207 msgids; there's little point to having them translated, since they
2208 can be understood only by someone who can read the
2209 (English-language) source code.
2211 Generate runtime-po/bison-runtime.pot automatically, so that we
2212 don't have to worry about garbage getting in that file. We'll
2213 make sure after the next official release that old msgids don't
2215 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
2217 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
2219 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
2220 Fix typos in explanations of the runtime file.
2221 * bootstrap: Change gettext keyword from YYI18N to YY_.
2222 Use standard Makefile.in.in in runtime-po, since we'll arrange
2223 for backward-compatible bison-runtime.po files in a different way.
2224 * data/glr.c (YY_): New macro, from yacc.c.
2225 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2226 Translate messages intended for users.
2227 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
2228 the wording in the other skeletons. We don't know that the memory
2230 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
2231 Use same method that yacc.c uses.
2232 Don't translate debugging messages.
2233 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
2234 it doesn't work (yet), and requires C++ expertise to fix.
2235 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
2236 Move defn to a more logical place, to be consistent with other
2238 Don't translate debugging messages.
2239 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
2240 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
2241 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
2242 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
2244 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
2245 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
2247 * tests/glr-regression.at (Badly Collapsed GLR States):
2249 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2250 yylex should return 0 at EOF rather than aborting.
2252 Improve tests for stack overflow in GLR parser.
2253 Problem reported by twlevo@xs4all.nl.
2254 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
2256 (yyStackOverflow): Just longjmp, but with value 2 so that caller
2257 can handle the problem.
2258 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
2259 (yyparse): New local variable yyresult to record the result.
2260 Use result of setjmp to set it, rather than storing itinto
2262 (yyDone): Remove label.
2263 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
2264 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
2265 if YYABORT is used).
2266 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
2267 yyparse status; put status > 1 into diagnostic.
2268 Check that status==2 works.
2269 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
2270 Use exit status 3 for failure to open (which shouldn't happen).
2272 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
2274 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
2275 1 on syntax error; just let yyparse do its thing.
2276 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
2277 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
2278 (Exploding the Stack Size with Alloca):
2279 (Exploding the Stack Size with Malloc):
2280 Expect exit status 2, not 1, since the parser is supposed to blow
2281 its stack. Problem reported by twlevo@xs4all.nl.
2283 * data/glr.c (yyparse): Don't assume that the initial calls
2284 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
2285 Print a stack-overflow message and fail instead.
2286 Initialize the line-number information before creating the stack,
2287 so that the stack-overflow message can report line zero safely.
2289 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
2291 Fix problems reported by twlevo@xs4all.nl.
2292 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
2293 (yyuserMerge): Provide a default case if b4_mergers is empty.
2294 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
2295 * tests/glr-regression.at
2296 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
2297 Add casts to pacify C++ compilers.
2298 * tests/glr-regression.at (Improper merging of GLR delayed action
2299 sets): Declare yylex before using it.
2300 * tests/Makefile.am (maintainer-check-g++): Fix a stray
2301 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
2302 test for valgrind; valgrind is independent of g++.
2303 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
2304 for compatibility with POSIX 1003.1-2001 (if running coreutils).
2305 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
2306 Use a destructor, so that we can expand the stack. Change
2307 YYSTYPE to char * so that we can free it. Cast result of malloc.
2309 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2311 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
2312 a valgrind failure. Problem reported by twlevo@xs4all.nl.
2314 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
2316 * PACKAGING: New file, suggested by Bruno Haible and taken from
2317 similar wording in gettext's PACKAGING file.
2318 * NEWS: Mention PACKAGING.
2319 * Makefile.am (EXTRA_DIST): Add PACKAGING.

2323 * NEWS: Document recent i18n improvements.
2324 * bootstrap: Get runtime translations into runtime-po.
2325 Create runtime-po files automatically, if possible.
2326 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
2327 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
2328 does not infringe on the user's name space.
2329 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
2330 * doc/bison.texinfo (Internationalization): Revamp the English
2331 and Texinfo syntax a bit, to try to make it clearer.
2332 (Bison Options, Option Cross Key): Mention --print-localedir.
2333 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
2334 YYENABLE_NLS. Quote a bit more.
2335 * runtime-po/.cvsignore: New file.

2344 * runtime-po/Makevars: Likewise.
2345 * runtime-po/LINGUAS: Likewise.
2346 * runtime-po/de.po: Likewise; we will rely on the translation project
2347 to maintain this, so "bootstrap" should get it.
2348 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
2350 * src/main.c (main): Bind the bison-runtime domain, too.
2352 2005-07-12 Bruno Haible <bruno@clisp.org>
2354 * data/yacc.c: Include <libintl.h> when NLS is enabled.
2355 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
2356 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
2357 * runtime-po: New directory.
2358 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
2359 $(DOMAIN).pot-update rule, so that old messages are never dropped.
2360 * runtime-po/Rules-quot: New file, copied from po/.
2361 * runtime-po/quot.sed: Likewise.
2362 * runtime-po/boldquot.sed: Likewise.

2373 * Makefile.am (SUBDIRS): Add runtime-po.
2374 (aclocaldir, aclocal_DATA): New variables.
2375 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
2377 * src/getargs.c (usage): Document --print-localedir option.
2378 (PRINT_LOCALEDIR_OPTION): New enum item.
2379 (long_options): Add --print-localedir option.
2380 (getargs): Handle --print-localedir option.
2381 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
2382 (Internationalization): New section.
2384 2005-07-12 Akim Demaille <akim@epita.fr>
2386 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
2387 for consistency with the rest of the code.
2388 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
2391 2005-07-12 Akim Demaille <akim@epita.fr>
2393 * src/parse-gram.y: Use %printer instead of YYPRINT.
2395 2005-07-12 Akim Demaille <akim@epita.fr>
2397 * src/symtab.h, src/symtab.c (symbol_print): New.
2398 * src/symlist.h, src/symlist.c (symbol_list_print): New.
2399 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
2401 2005-07-12 Akim Demaille <akim@epita.fr>
2403 * data/glr.c (b4_syncline): Fix (swap) the definitions of
2404 b4_at_dollar and b4_dollar_dollar.
2406 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
2408 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
2409 and Pennello's paper.
2411 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
2413 * data/yacc.c (yyparse): Undo previous patch. Instead,
2414 set yylsp[0] and yyvsp[0] only if the initial action
2415 sets yylloc and yylval, respectively.
2417 * data/yacc.c (yyparse): In the initial action, set
2418 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
2419 This avoids the use of undefined variables if the initial
2420 action does not set yylloc and/or yylval.
2422 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2424 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
2425 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
2426 Remove from CVS. These files are automatically generated.
2427 * examples/extexi: Clarify that this file is now part of Bison,
2428 not GNU M4, and that it works with any POSIX-compatible Awk.
2429 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
2430 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
2431 so that we also get calc++-parser.yy. Geneate it.
2432 Use $(AWK), not gawk, since any conforming Awk will do.
2433 Put comment before action, since older 'make' can't handle comment
2435 $(BUILT_SOURCES): List all built sources, not just some of them.
2436 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
2437 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
2438 $($(calc_sources_generated)): Remove unnecessary test for existence
2439 of target. (This had a shell syntax error anyway; a stray "x".)
2440 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
2442 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
2444 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
2445 implied by the other modules.
2447 2005-07-06 Akim Demaille <akim@epita.fr>
2449 Bind examples/calc++ to the package.
2450 * examples/calc++/Makefile: Remove, replaced by...
2451 * examples/calc++/Makefile.am: ... this new file.
2452 * examples/calc++/test: Remove input.
2453 * examples/calc++/compile: Remove.
2454 * examples/Makefile.am: New.
2455 * configure.ac, Makefile.am: Adjust.
2456 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
2458 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
2460 * data/glr.c (yyFail): Drastically simplify; since the format argument
2461 never had any % directives, we can simply pass it to yyerror.
2462 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
2463 be modified later, as that is the usual style in glr.c.
2464 Problems reported by Paul Hilfinger.
2466 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
2467 and size overflow errors.
2468 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
2469 in case the user prolog sets feature-test macros like _GNU_SOURCE.
2470 (YYSIZEMAX): New macro.
2471 (yystpcpy): New function, taken from yacc.c.
2472 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
2473 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
2474 so that we don't have to maintain their signatures.
2475 (yyFail): Check for buffer overflow, by using vsnprintf rather
2476 than vsprintf. Allocate a bigger buffer if possible.
2477 Report an error if buffer allocation fails.
2478 (yyStackOverflow): New function.
2479 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
2480 the initialization was successful. It might fail if storage was
2482 (yyexpandGLRStack): Add more checks for storage allocation failure.
2483 Use yyStackOverflow to report failures.
2484 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
2485 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
2486 Don't assume stack number fits in int.
2487 (yysplitStack): Check for storage allocation failure.
2488 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
2489 can print diagnostics on storage allocation failure. All callers
2491 (yyresolveValue): Use yybool for boolean.
2492 (yyreportSyntaxError): Check for size-calculation overflow.
2493 This code is taken from yacc.c.
2494 (yyparse): Check for storage allocation errors when allocating
2497 2005-07-05 Akim Demaille <akim@epita.fr>
2499 Extract calc++ from the documentation.
2500 * doc/bison.texinfo (Calc++): Add the extraction marks.
2501 * examples/extexi: New, from the aborted GNU Programming 2E.
2502 Separate the different paragraph of a file with empty lines.
2503 * examples/Makefile: Use it to extract the whole calc++ example.
2505 2005-06-24 Akim Demaille <akim@epita.fr>
2507 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
2510 2005-06-22 Akim Demaille <akim@epita.fr>
2512 * doc/bison.texinfo (C++ Language Interface): First stab.
2513 (C++ Parsers): Remove.
2515 2005-06-22 Akim Demaille <akim@epita.fr>
2517 * data/lalr1.cc (yylex_): Honor %lex-param.
2519 2005-06-22 Akim Demaille <akim@epita.fr>
2521 Start a set of simple examples.
2522 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
2523 * examples/calc++/calc++-driver.hh,
2524 * examples/calc++/calc++-parser.yy,
2525 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
2526 * examples/calc++/compile, examples/calc++/test: New.
2528 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
2530 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2531 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2532 which stems from the 2005-05-27 patch.
2534 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2536 * data/glr.c: Modify treatment of unused parameters to permit use
2537 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2539 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2541 Fix infringement on user name space reported by Janos Zoltan Szabo.
2542 * data/yacc.c (yyparse): strlen -> yystrlen.
2544 2005-05-30 Akim Demaille <akim@epita.fr>
2546 * data/lalr1.cc (_): New.
2547 Translate the various messages.
2549 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2551 Fix infringement on user name space reported by Bruno Haible.
2552 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2553 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2554 the user's name space.
2555 (alloca): Include <stdlib.h> to get it, if it's not built in.
2556 (YYMALLOC, YYFREE): Define only if needed.
2557 (malloc, free): Declare, but only if needed, as this infringes on
2558 the user name space.
2560 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2562 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
2563 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
2565 * lib/ebitset.c (min, max): Undef before defining.
2566 * lib/vbitset.c (min, max): Likewise.
2567 * lib/subpipe.c (create_subpipe): Save local variables in case
2568 vfork clobbers them.
2570 2005-05-24 Bruno Haible <bruno@clisp.org>
2572 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
2573 error message syntax used by gcc-4.0.
2575 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
2577 * README: Mention m4 1.4.3. Remove obsolete advice about
2578 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
2580 * bootstrap: Remove workaround for problem I encountered with
2581 gettext 0.14.1; it seems to be fixed now.
2583 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
2585 * NEWS: Version 2.0a.
2587 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2588 the previous change.
2590 Various maintainer cleanups.
2591 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2592 conftest*, for benefit of CVS commands run at the same time as
2593 "configure". Add build-aux, since "bootstrap" now creates it and
2595 * Makefile.cfg (move_if_change): Remove.
2596 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2597 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

2599 (config.guess-url_prefix, config.sub-url_prefix):
2600 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

2602 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
2604 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
2605 this is now the recommended name.
2606 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2607 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2608 ylwrap. These files now go into build-aux.
2609 * config/move-if-change: Remove.
2610 * config/prev-version.txt: Bump from 1.75 to 2.0.
2612 * bootstrap: Add stdio-safer, unistd-safer modules.
2613 Remove m4/glibc2.m4 (introduced by latest gnulib, but
2615 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
2616 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2617 * lib/subpipe.c: Include "unistd-safer.h".
2618 (create_subpipe): Make sure all the newly-created
2619 file descriptors are > 2, so that diagnostics don't
2620 get sent down them (which might cause Bison to hang, in theory).
2621 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2622 * src/files.c (xfopen): Use fopen_safer, not fopen.
2624 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2625 yesterday's yacc.c fix.
2627 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
2629 * data/glr.c, data/lalr1.cc: Update copyright date.
2631 Fix a destructor bug reported by Wolfgang Spraul in
2632 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
2633 * data/yacc.c (yyabortlab): Don't call destructor, and
2634 don't set yychar to EMPTY.
2635 (yyoverflowlab): Don't call destructor.
2636 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2637 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2638 since we no longer output the message "discarding lookahead token
2641 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2643 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2644 fix a small glitch in debugging output.
2645 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2646 after YY_SYMBOL_PRINT where needed.
2648 (struct yyGLRState): Add some comments.
2649 (struct yySemanticOption): Add some comments.
2650 (union yyGLRStackItem): Add comment.
2652 (yymergeOptionSets): Correct this to properly perform the union,
2653 avoiding infinite reported by Michael Rosien.

2697 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
2699 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
2700 Problem reported by Ralf Menzel.
2702 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2704 * tests/actions.at: Test that stack overflow invokes destructors.
2705 From Marcus Holland-Moritz.
2706 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2708 (yyreturn): to here. That way, destructors are called properly
2709 even if the stack overflows, or the user calls YYACCEPT or
2710 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2711 (yyoverflowlab): Destroy the lookahead.
2713 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2715 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2717 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2719 * NEWS: Bison-generated C parsers no longer quote literal strings
2720 associated with tokens.
2721 * src/output.c (prepare_symbols): Don't escape strings,
2722 since users don't want to see C escapes.
2723 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2725 * tests/input.at (Torturing the Scanner): Likewise.
2726 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2728 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2730 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2731 the data size is known to be too small and we can't increase it.
2732 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2734 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2736 * src/parse-gram.y: Include quotearg.h.
2737 (string_as_id): Quote $1 before using it as a key, since the
2738 lexer no longer quotes it for us.
2739 (string_content): Don't strip quotes, since lexer no longer
2741 * src/scan-gram.l: Include quotearg.h.
2743 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2744 a key, since the rest of the lexer doesn't quote it.
2745 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2746 * tests/regression.at (Token definitions): Check for backslashes
2749 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2750 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2751 (yyparse): Revamp code to generate long syntax error message, to
2752 make it easier to translate, and to avoid problems with arithmetic
2753 overflow. Change "virtual memory" to "memory" in diagnostic, since
2754 we don't know whether the memory is virtual.
2756 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2758 * NEWS: Bison-generated C parsers now use the _ macro to
2760 * data/yacc.c (_) [!defined _]: New macro.
2761 All English strings wrapped inside this macro.
2762 * doc/bison.texinfo (Bison Parser): Document _.
2763 * po/POTFILES.in: Include src/parse-gram.c, since it now
2764 includes translateable strings that parse-gram.y doesn't.
2766 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2768 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2769 reverting the 2004-10-11 change to this function.
2770 (symbol_check_alias_consistency): Don't call symbol_type_set
2771 if the type name is already correct.
2772 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2774 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2776 * tests/regression.at (Token definitions): Don't use a token named
2777 c, as that generates a "#define c ..." that runs afoul of buggy
2778 stdlib.h that uses the identifier c as a member of struct
2779 drand48_data. Problem reported by Horst Wente.
2781 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2783 * bootstrap: Change translation URL from
2784 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2785 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2786 redirection glitches. Problem reported by twlevo@xs4all.nl.
2788 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2790 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2791 after operands; POSIX says this isn't portable for the c99 command.
2793 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2795 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2796 immediately if a data overrun has occurred; this may help us track
2797 down what may be a spurious failure on MacOS.
2799 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2801 Respond to problems reported by twlevo@xs4all.nl.
2803 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
2805 * src/vcg.h: Comment fix.
2806 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2807 (G_CMAX): Change to -1 instead of INT_MAX.
2809 * data/yacc.c (yyparse): Omit spaces before #line.
2811 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2813 * src/tables.c (state_number_to_vector_number): Put it inside an
2814 "#if 0", since it's not currently used. Problem reported by
2817 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2819 * src/output.c (escaped_output): Renamed from
2820 escaped_file_name_output, since we now use it for symbol tags as
2821 well. All uses changed.
2822 (symbol_destructors_output, symbol_printers_output):
2823 Escape symbol tags too.
2824 Problem reported by Matyas Forstner in
2825 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2827 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2829 * src/output.c (user_actions_output, token_definitions_output,
2830 symbol_destructors_output, symbol_printers_output): Likewise.
2831 * src/reader.c (prologue_augment): Likewise.
2832 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2834 * src/vcg.c (output_edge): Don't quote linestyle arg.
2835 Problem reported by twlevo@xs4all.nl.
2837 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2839 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2840 example, reported by Derek M Jones. Also, make the example even
2841 more outrageous, to better illustrate how bad the problem is.
2843 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2845 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2846 putsym. Typo reported by Sebastian Piping.
2848 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2850 * doc/bison.texinfo (Language and Grammar): some -> same
2851 (Epilogue): int he -> in the
2852 Typos reported by Sebastian Piping via Justin Pence.
2854 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2856 * tests/glr-regression.at (Improper handling of embedded actions
2857 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2858 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2859 with dollar signs in test names.
2860 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2861 for a similar reason.
2863 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2865 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2866 wants to redefine G_VIEW.
2868 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
2870 * src/vcg.c (get_view_str): Remove case for normal_view.
2871 Problem reported by twlevo@xs4all.nl.
2873 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
2875 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
2876 Problem reported by twlevo@xs4all.nl.
2878 * doc/bison.texinfo: Change @dircategory from "GNU programming
2879 tools" to "Software development". Requested by Richard Stallman
2882 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
2884 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
2885 Problem reported by twlevo@xs4all.nl.
2887 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2889 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2890 keyword; it's not needed with modern compilers, and it doesn't
2891 affect correctness with older compilers. Suggested by
2894 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2896 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2897 gcc -Wswitch-default.
2898 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2899 * data/yacc.c (yyparse): Likewise.
2901 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2903 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2904 already. Let config.h define any nonstandard values.
2906 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2908 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2909 for the benefit of slower hosts. Problem reported by
2912 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2914 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2915 being defined and not used.
2916 * data/lalr1.cc (yyparse): Likewise.
2917 Use "if (false)" rather than "if (0)".
2919 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2921 * TODO: Mention that we should allow NUL bytes in tokens.
2923 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
2925 * src/scan-skel.l (<<EOF>>): Don't close standard output.
2926 Problem reported by Hans Aberg.
2928 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
2930 * src/getargs.c (version): Happy new year; update overall
2931 program copyright date from 2004 to 2005.
2933 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2934 Problem reported by Hans Aberg.
2935 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2936 (Output file names.): Add a test for the case when standard output
2939 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2941 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2942 to fix an oversight in the Bison 2.0 manual.
2944 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2946 * NEWS: Version 2.0. Reformat the existing news items since
2947 1.875, so that related items are grouped together.
2948 * configure.ac (AC_INIT): Bump version to 2.0.
2949 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2951 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2952 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2953 otherwise, we're not testing alloca. Unfortunately there's no
2954 simple way to consult HAVE_ALLOCA here.
2956 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2959 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2960 hand. This avoids a warning about comparing int to size_t when
2961 GCC warnings are enabled.
2963 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2965 * NEWS: Bison-generated parsers no longer default to using the
2966 alloca function (when available) to extend the parser stack, due
2967 to widespread problems in unchecked stack-overflow detection.
2968 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2969 responsibility to set it to a positive value. This lets the user
2970 specify a value that is not a preprocessor constant.
2971 * data/yacc.c (YYMAXDEPTH): Likewise.
2972 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2973 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2974 to be a compile-time constant. However, explain the constraints on it.
2975 Also, explain the constraints on YYINITDEPTH.
2976 (Table of Symbols): Explain that alloca is no longer the default.
2977 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2980 * doc/bison.texinfo (Location Default Action): Mention that n must
2981 be zero when k is zero. Suggested by Frank Heckenbach.
2983 2004-12-22 Akim Demaille <akim@epita.fr>
2985 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
2986 (parser::state_type, parser::semantic_type, parser::location_type):
2987 Private, not public.
2988 (parser::parse): Return ints, not bool.
2989 Returning a bool introduces a problem: 0 corresponds to false, and
2990 it seems weird to return false on success. Returning true changes
2991 the conventions for yyparse.
2992 Alternatively we could return void and send an exception.
2993 There is no clear consensus (yet?).
2994 (state_stack, semantic_stack, location_stack): Rename as...
2995 (state_stack_type, semantic_stack_type, location_stack_type): these.
2996 Private, not public.
2997 * tests/c++.at: New.
2998 * tests/testsuite.at, tests/Makefile.am: Adjust.
3000 2004-12-21 Akim Demaille <akim@epita.fr>
3002 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
3004 2004-12-21 Akim Demaille <akim@epita.fr>
3006 Don't impose std::string for filenames.
3008 * data/lalr1.cc (b4_filename_type): New.
3009 (position::filename): Use it.
3010 (parser.hh): Move the inclusion of stack.hh and location.hh below
3011 the user code, so that needed headers for the filename type can be
3013 Forward declare them before the user code.
3014 * tests/Makefile.am (check-local, installcheck-local): Pass
3015 TESTSUITEFLAGS to the TESTSUITE.
3017 2004-12-20 Akim Demaille <akim@epita.fr>
3019 Use more STL like names: my_class instead of MyClass.
3021 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
3022 (SemanticStack, SemanticType, StateStack, StateType)
3023 (TokenNumberType, Stack, Slice, Traits, Parser::location)
3024 (Parser::value): Rename as...
3025 (location_stack, location_type, rhs_number_type, semantic_stack)
3026 (semantic_type, state_stack, state_type, token_number_type, stack)
3027 (slice, traits, parser::yylloc, parser::yylval): these.
3029 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
3031 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
3033 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
3034 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
3036 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
3038 Remove uses of 'short int' and 'unsigned short int'. This raises
3039 some arbitrary limits. It uses more memory but nowadays that's
3040 not much of an issue.
3042 This change does not affect the generated parsers; that's a different
3043 task, as some users will want to conserve memory there.
3045 Ideally we should use size_t to represent all object counts, and
3046 something like ptrdiff_t to represent signed differences of object
3047 counts; but that will require more code-cleanup than I have the
3048 time to do right now.
3050 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
3051 Use size_t, not int or short int, to count objects.
3052 * src/closure.c (nritemset, closure): Likewise.
3053 * src/closure.h (nritemset, closure): Likewise.
3054 * src/nullable.c (nullable_compute): Likewise.
3055 * src/print.c (print_core): Likewise.
3056 * src/print_graph.c (print_core): Likewise.

3059 * src/tables.c (default_goto, goto_actions): Likewise.
3061 * src/gram.h (rule_number, rule): Use int, not short int.
3062 * src/output.c (prepare_rules): Likewise.
3063 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
3064 errs, reductions): Likewise.
3065 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
3067 * src/tables.c (vector_number, tally, action_number,
3068 ACTION_NUMBER_MINIMUM): Likewise.
3069 * src/output.c (muscle_insert_short_int_table): Remove.
3071 2004-12-17 Akim Demaille <akim@epita.fr>
3073 * data/lalr1.cc: Extensive Doxygenation.
3074 (error_): Rename as...
3075 (error): this, since it is visible to the user.
3077 (Parser::message): Now an automatic variable from...
3078 (Parser::yyreport_syntax_error_): here.
3079 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
3081 * tests/input.at: Escape $.
3083 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
3085 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
3086 Parenthesize rhs to avoid obscure problems with mistakes like
3087 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
3088 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
3089 b4_rhs_location): Likewise.
3090 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
3091 b4_rhs_location): Likewise.
3093 2004-12-16 Akim Demaille <akim@epita.fr>
3095 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
3096 yacc.c: be sure to stay within yycheck_.
3097 * tests/actions.at: Re-enable C++ tests.
3099 2004-12-16 Akim Demaille <akim@epita.fr>
3101 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
3104 2004-12-16 Akim Demaille <akim@epita.fr>
3106 Use #define to handle the %name-prefix.
3108 * data/glr.c, data/yacc.c: Comment changes.
3109 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
3110 so that one can refer to yylex in the parser file, and have it
3111 renamed, as is the case with other skeletons.
3113 2004-12-16 Akim Demaille <akim@epita.fr>
3115 Move lalr1.cc internals into yy*.

3135 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
3137 Fix some problems reported by twlevo at xs4all.
3138 * src/symtab.c (symbol_new): Report an error if the input grammar
3139 contains too many symbols. This is better than calling abort() later.
3140 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
3141 (struct node, struct graph):
3142 Rename member expand to stretch. All uses changed.
3143 (struct graph): Remove member layoutalgorithm. All uses removed.

3149 2004-12-15 Akim Demaille <akim@epita.fr>
3151 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
3152 Add more Doxygen comments.
3153 (symprint_, stack_print_, reduce_print_, destruct_, pop)
3154 (report_syntax_error_, translate_): Rename as...
3155 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
3156 (yypop_, yyreport_syntax_error_, yytranslate_): this.
3158 2004-12-15 Akim Demaille <akim@epita.fr>
3160 * data/lalr1.cc (lex_): Rename as...
3162 Move the trace here.
3163 Take the %name-prefix into account.
3164 Reported by Alexandre Duret-Lutz.
3166 2004-12-15 Akim Demaille <akim@epita.fr>
3168 Simplify the C++ parser constructor.
3170 * data/lalr1.cc (debug_): Rename as...
3171 (yydebug_): so that the parser's internals are always in the yy*
3174 (b4_parse_param_decl): Remove the leading comma as it is now only
3175 called as unique argument list.
3176 (Parser::Parser): Remove the constructor accepting a location and
3177 an initial debugging level.
3178 Remove from the other ctor the argument for the debugging level.
3179 (debug_level_type, debug_level, set_debug_level): New.
3181 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
3184 2004-12-15 Akim Demaille <akim@epita.fr>
3186 Remove b4_root related material: failure experiment
3187 (which goal was to allow to derive from a class).
3189 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
3190 definitions and uses.
3192 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
3194 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
3195 not 2, since it's not portable to subtract 1 from the start of an
3196 array. The new item 0 is never set or used. All uses changed.
3198 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
3199 the default definition of YYLLOC_DEFAULT. Problem reported
3200 by Frank Heckenbach.
3202 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
3204 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
3205 the normal case and one for the error case. Just use the
3206 first one uniformly. Problem reported by Frank Heckenbach.
3207 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
3208 use exactly the same macro in both places.
3209 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
3210 so that the normal-case YYRHSLOC works for the error case too.
3212 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
3213 (YYLLOC_DEFAULT): Use the same macro as glr.c.
3214 * doc/bison.texinfo (Location Default Action): Don't claim that
3215 we have an array of locations. Use the same macro for both glr
3216 and lalr parsers. Mention YYRHSLOC. Mention what happens when
3219 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
3221 * HACKING: Update email addresses to send announcements to.
3223 * configure.ac (AC_INIT): Bump version to 1.875f.
3225 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
3227 * NEWS: Version 1.875e.
3228 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
3230 * src/scan-skel.l: Include "complain.h", for "fatal".
3232 * src/relation.h (relation_print, relation_digraph):
3233 Relation sizes are of type relation_node, not size_t (this is
3234 merely a doc fix, since the two types are equivalent).
3235 (relation_transpose): Relation sizes are of type relation_node,
3237 * src/relation.c: Likewise.
3238 (top, infinity): Now of type relation_node, not int.
3239 (traverse, relation_transpose): Use relation_node, not int.
3241 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
3242 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
3243 (yyparse): Remove unused local introduced in 2004-10-25 patch.
3245 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
3246 specifying whether the test should be skipped. Use it tp
3247 specify that the [%defines %skeleton "lalr1.cc"] tests currently
3248 fail on some hosts, and should be skipped.
3250 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3252 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
3253 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
3254 unless otherwise specified below.
3256 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
3257 to allocate kernel_base, kernel_items, kernel_size, since
3258 they needn't be initialized to 0.
3259 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
3260 * src/closure.c (new_closure): Likewise, for itemset.
3261 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

3275 (save_column): Likewise for froms[symno], tos[symno].
3276 (goto_actions): Likewise for state_count.
3277 (pack_table): Likewise for base, pos, check.
3278 (tables_generate): Likewise for width.
3280 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
3281 for initial core. Just have a separate core, so we needn't worry
3282 about whether kernel_size and kernel_base are initialized.
3284 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
3285 kernel_size, kernel_items): Remove unnecessary initialization.
3286 * src/conflicts.c (conflicts): Likewise.

3290 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
3291 conflrow, conflict_table, conflict_list, table, check):
3294 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
3295 This is because all callers pass unsigned int.
3296 * src/closure.h (new_closure): Likewise.
3298 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
3299 (build_relations): Initialize includes[i] in all cases.
3300 * src/reader.c (packgram): Always initialize rules[ruleno].prec
3301 and rules[ruleno].precsym. Initialize members in order.
3302 * src/relation.c (relation_transpose): Always initialize new_R[i]
3304 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
3306 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
3307 conflict_list[0] was always 0, but now it isn't initialized.
3309 * src/table.c (table_grow): When conflict_table grew, the grown
3310 area wasn't cleared. Fix this.
3312 * lib/.cvsignore: Add strdup.c, strdup.h.
3313 * m4/.cvsignore: Add strdup.m4.
3315 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
3317 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
3318 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
3319 GOTO_NUMBER_MAXIMUM, since we occasionally compute
3320 ngotos + 1 without checking for overflow.
3321 (build_relations): Use END_NODE, not -1, to denote end of edges.
3322 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
3323 build_relations): Use goto_number, not int, for goto numbers.
3324 * src/tables.c (save_column, default_goto): Likewise.
3326 2004-11-23 Akim Demaille <akim@epita.fr>
3328 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
3329 of #defining from yystype.
3330 Don't typedef yystype, C++ does not need it.
3331 This lets it possible to forward declare it as union.
3333 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
3335 * bootstrap (gnulib_modules): Add extensions.
3336 Problem reported by Jim Meyering.
3338 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
3340 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
3341 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
3342 src/system.h, src/tables.c: XFREE -> free, to accommodate
3343 recent change to gnulib xalloc.h.
3344 Problem reported by Jim Meyering.
3346 2004-11-17 Akim Demaille <akim@epita.fr>
3348 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
3350 2004-10-28 Akim Demaille <akim@epita.fr>,
3351 Alexandre Duret-Lutz <adl@gnu.org>
3353 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
3356 Use it instead of cdebug_.
3357 (Parser::debug_stream, Parser::set_debug_stream): New.
3358 (Parser::symprint_): Define cdebug_ for temporary backward
3360 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
3363 2004-11-17 Akim Demaille <akim@epita.fr>
3365 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
3366 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
3367 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
3368 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
3370 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
3372 * data/glr.c (yyloc_default): Remove; not used.
3373 Problem reported by Frank Heckenbach.
3375 2004-10-25 Akim Demaille <akim@epita.fr>
3377 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
3378 Introduce another definition to address simple location arrays.
3379 (yyGLRStack): New member: yyerror_range.
3380 (yyrecoverSyntaxError, yyparse): Update it.
3381 (yyrecoverSyntaxError): Use it when shifting the error token to
3382 have an accurate range, equivalent to the one computed by both
3383 yacc.c and lalr1.cc.
3384 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
3385 that column numbers start at column 0, as per GNU Coding
3386 Standards, the others tests, and the doc.
3387 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
3388 Adjust to the above change (first column is 0).
3389 And adjust the location of the "<error>", now covering the whole
3392 2004-10-22 Akim Demaille <akim@epita.fr>
3393 and Paul Eggert <eggert@cs.ucla.edu>
3395 Remove some arbitrary limits on goto numbers and relations.
3396 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
3397 initial values, since they're never used.
3398 (set_goto_map): ngotos is now unsigned, so test for overflow
3399 by seeing whether it wraps around to zero.
3400 * src/lalr.h (goto_number): Now size_t, not short int.
3401 (GOTO_NUMBER_MAXIMUM): Remove.
3402 * src/relation.c (relation_print, traverse, relation_transpose):
3403 Check for END_NODE rather than looking at sign.
3404 * src/relation.h (END_NODE): New macro.
3405 (relation_node): Now size_t, not short int.
3407 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
3409 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
3410 keyword, not an identifier. Problem reported by Baron Schwartz in
3411 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
3413 2004-10-11 Akim Demaille <akim@epita.fr>
3415 * src/symtab.c (symbol_check_alias_consistency): Also check
3416 type names, destructors, and printers.
3417 Reported by Alexandre Duret-Lutz.
3418 Recode the handling of associativity and precedence in terms
3419 of symbol_precedence_set.
3420 Accept no redeclaration at all, not even equal to the previous
3422 (redeclaration): New.
3423 Use it to factor redeclaration complaints.
3424 (symbol_make_alias): Don't set the type of the alias, let
3425 symbol_check_alias_consistency do it as for other features.
3426 * src/symtab.h (symbol): Add new member prec_location, and
3428 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
3429 * tests/input.at (Incompatible Aliases): New.
3431 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
3433 .cvsignore fixes to accommodate gnulib changes,
3434 and the practice of naming build directories "_build".
3435 * .cvsignore: Add "_*". Sort.
3436 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
3437 * m4/.cvsignore: Add "*_gl.m4".
3439 2004-10-06 Akim Demaille <akim@epita.fr>
3441 * src/parse-gram.y (add_param): Fix the truncation of trailing
3444 2004-10-05 Akim Demaille <akim@epita.fr>
3446 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3447 whether the reducion was empty or not. This leaves room to
3448 improve the use of YYLLOC_DEFAULT in such a case.
3449 lalr1.cc is still experimental, so changing this is acceptable.
3450 And finally, there are probably not many users who changed the
3451 handling of locations in GLR, so changing is admissible too.
3453 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3454 empty reduction, set @$ to an empty location ending the previously
3456 Adjust uses to make sure the code is triggered on empty
3458 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
3459 expected output: empty reductions have empty locations.
3461 2004-09-29 Akim Demaille <akim@epita.fr>
3463 * data/lalr1.cc: Move towards a more standard C++ coding style
3464 for templates: Class < T > -> Class<T>.
3466 2004-09-29 Akim Demaille <akim@epita.fr>
3468 * data/lalr1.cc: Reinstall the former ctor, for sake of
3469 compatibility, but warn it will be removed.
3470 Move towards a more standard C++ coding style (i.e., type *var ->
3473 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
3475 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
3476 since it's less likely to work if NULs are involved in the future.
3478 2004-09-27 Akim Demaille <akim@epita.fr>
3480 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
3482 2004-09-27 Akim Demaille <akim@epita.fr>
3484 * data/lalr1.cc (b4_parse_param_decl_1): New.
3485 (b4_parse_param_decl): Use it to have different names between attribute
3487 (b4_cc_constructor_call): Likewise.
3489 2004-09-24 Akim Demaille <akim@epita.fr>
3491 * src/parse-gram.y (add_param): Strip the leading and trailing
3492 blanks from a formal argument declaration.
3493 (YY_LOCATION_PRINT): New.
3495 2004-09-24 Akim Demaille <akim@epita.fr>
3497 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
3500 2004-09-24 Akim Demaille <akim@epita.fr>
3502 * doc/bison.texinfo (Table of Symbols): Sort.
3504 2004-09-21 Akim Demaille <akim@epita.fr>
3506 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
3507 the useless parentheses.
3508 Suggested by Paul Eggert.
3510 2004-09-20 Akim Demaille <akim@epita.fr>
3512 Let the initial-action act on the look-ahead, and use it for the
3513 "initial push" (corresponding to an hypothetical beginning-of-file).
3514 And let lalr1.cc honor %initial-action.
3516 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
3518 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3519 (Parser::Parser): Remove the ctor that used to initialize it.
3520 (Parser::parse): Like in the other skeletons, issue the "starting
3521 parse" message before any action.
3522 Honor %initial-action.
3523 Initialize the stacks with the lookahead.
3524 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3526 Push them in the stacks.
3527 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3529 2004-09-20 Akim Demaille <akim@epita.fr>
3531 * doc/bison.texinfo (Initial Action Decl): New.
3533 2004-09-20 Akim Demaille <akim@epita.fr>
3535 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3536 clearer criterion to define it.
3537 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3538 When reducing on an empty RHS, use the latest stacked location as
3540 yylloc is not always available.
3541 * data/glr.c: Likewise.
3542 Also, honor initial-actions.
3544 2004-09-20 Akim Demaille <akim@epita.fr>
3546 * data/yacc.c (YY_LOCATION_PRINT): New.
3547 Define when we know YYLTYPE's structure, i.e., when the default
3548 YYLLOC_DEFAULT is used.
3549 * data/c.m4 (b4_yysymprint_generate): Use it.
3550 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3551 value of the result.
3552 (error_start_): Replace with...
3553 (error_range_): this location array.
3554 This allows to replace code relying on the implementation of
3555 locations by portable code.
3556 * data/yacc.c (yylerrsp): Replace with...
3557 (yyerror_range): this.
3558 Every time a token is popped, update yyerror_range[0], to have an
3559 accurate location for the error token.
3560 * data/glr.c (YY_LOCATION_PRINT): New.
3561 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3562 deference a pointer.
3563 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3564 report the location in %printers.
3566 * src/scan-skel.l: Instead of abort, report error messages to ease
3567 understanding skeleton scanning failures.
3569 2004-09-16 Akim Demaille <akim@epita.fr>
3571 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3572 (iterator, const_iterator): these, to be more in the C++ spirit.
3573 Also, return reverse iterators so that when displaying the stack
3574 we display its bottom first.
3575 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3577 We should probably use vector here though.
3579 2004-09-16 Akim Demaille <akim@epita.fr>
3581 Have more complete shift traces.
3583 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3584 to report Shifts instead of ad hoc YYDPRINTF invocations,
3585 including for the error token.
3586 * data/lalr1.cc (symprint_): Output the location.
3587 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3588 output the location within the %printer.
3589 Activate GLR tests, at least to make sure they compile properly.
3590 They still don't pass though.
3591 * tests/calc.at: Adjust expect verbose output, since now "Entering
3592 state..." is on a different line than the "Shifting" message.
3594 2004-09-08 Akim Demaille <akim@epita.fr>
3596 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3597 Bison directive from the Bison file to the invocation of this
3598 macro, so that these directives are passed to
3599 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3600 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3601 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3602 the extra Bison directives instead of the whole series.
3603 Change the grammar so that there are recoverable errors, and
3604 unrecoverable errors. Now we can have the parser give up before
3605 consuming the whole input. As a result we now can observe that
3606 the lookahead is freed when needed.
3607 Change the parser source to parse argv[1] instead of a hard coded
3609 Simplify yylex, and give a value and location to EOF.
3610 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3611 passed directives already coded in the file.
3612 Add some tests to check the location of "error".
3613 For some tests, the C++ parser is correct, and not yacc.c.
3614 For other tests, they provide different, but unsatisfying, values,
3615 so keep the C++ value so that at least one parser is "correct"
3616 according to the test suite.
3617 (Actions after errors): Remove, this is subsumed by the
3618 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3620 2004-09-06 Akim Demaille <akim@epita.fr>
3622 * data/lalr1.cc: Adjust the indentation of the labels.
3626 2004-09-06 Akim Demaille <akim@epita.fr>
3628 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3629 argument, an informative message.
3630 Call YY_SYMBOL_PRINT.
3631 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3632 * data/lalr1.cc (destruct_): Likewise.
3633 In addition, no longer depend on b4_yysymprint_generate and
3634 b4_yydestruct_generate to generate these functions, do it "by
3637 2004-09-03 Akim Demaille <akim@epita.fr>
3639 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3640 invoked, yydestruct the lookahead.
3641 * tests/calc.at (Calculator $1): Update the expected lengths of
3642 traces: there is an added line for the discarded lookahead.
3643 * doc/bison.texinfo (Destructor Decl): Some rewording.
3644 Define "discarded" symbols.
3646 2004-09-02 Akim Demaille <akim@epita.fr>
3648 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3650 2004-09-02 Akim Demaille <akim@epita.fr>
3652 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3653 (YYDSYMPRINTF): Rename as...
3654 (YY_SYMBOL_PRINT): this.
3655 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3657 Use it instead of direct symprint_ calls.
3658 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3661 2004-09-02 Akim Demaille <akim@epita.fr>
3663 * data/lalr1.cc (b4_yysymprint_generate): New.
3664 (symprint_): New member function, defined when YYDEBUG.
3665 Use it consistently instead of token/nterm debugging output by
3667 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
3668 %printer calls to use cdebug_ when using lalr1.cc.
3670 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
3672 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
3673 with #ifdef YYDEBUG.
3675 2004-08-26 Akim Demaille <akim@epita.fr>
3677 * doc/bison.texinfo (Implementing Loops): Rename as...
3678 (Implementing Gotos/Loops): this.
3680 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
3682 Adjust to latest gnulib.
3683 * bootstrap (gnulib_modules): Add xalloc-die.
3684 Set LC_ALL=C so that file names sort consistently.
3685 Prefer the gnulib copies of gettext.m4, glibc21.m4,
3686 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
3687 uintmax_t.m4, ulonglong.m4.
3688 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
3689 po.m4 since we are now using _gl.m4 instead.
3691 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
3693 * src/scan-action.l: Remove. Scanning of semantic actions is
3694 handled in scan-gram.l.
3696 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
3698 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
3700 * src/location.h (struct): The file member is a uniqstr.
3701 (equal_boundaries): Use UNIQSTR_EQ for comparison.
3703 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
3705 Fix bug with non-%union parsers that have printers or destructors,
3706 which led to a Bison core dump. Reported by Peter Fales in
3707 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
3709 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
3710 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
3711 not to our own type.
3712 * src/output.c (symbol_destructors_output, symbol_printers_output):
3713 Don't assume %union.
3714 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
3715 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
3716 UNION-FLAG. All callers changed.
3717 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3718 Use type char, not unsigned int, when declaring an array of char;
3719 this lets us remove a cast.
3720 (Printers and Destructors): Add non-%union test cases.
3722 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3724 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3725 GLR writeups. E.g., avoid frenchspacing and the future tense,
3726 change "lookahead" to "look-ahead", and change "wrt" to "with
3729 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3731 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
3732 New sections, split off from the GLR Parsers section. Put the new
3733 Simple GLR Parser near the start of the GLR section, for clarity.
3734 Rewrite connective text.
3736 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
3738 * doc/bison.texinfo (Simple GLR Parsers): New section.
3740 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3742 * NEWS, TODO, doc/bison.texinfo:
3743 Use "look-ahead" instead of "lookahead", to be consistent.
3744 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
3745 while we're fixing "look-ahead".
3746 * src/conflicts.c (shift_set): Renamed from shiftset.
3747 (look_ahead_set): Renamed from lookaheadset.
3748 * src/print.c: Likewise.

3767 * README: Update location of patched M4 distribution.
3769 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
3771 Don't assume the C++ compiler takes the same arguments as the C compiler
3773 * configure.ac (O0CXXFLAGS): New var.
3774 * tests/atlocal.in (CXXFLAGS): Use it.
3776 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
3778 Fix some "make check" problems with C++ reported by
3779 Albert Chin-A-Young for Tru64 C++ in this thread:
3780 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
3782 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
3783 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3784 Output to a .cc file for C++, not to a .c file.
3785 * tests/calc.at (AT_CHECK_CALC): Likewise.
3786 * tests/regression.at (AT_CHECK_DANCER): Likewise.
3787 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.

3792 C++ compiler. (trivial change)
3794 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
3796 Spent a few hours checking out which prerequisite versions the
3797 current sources actually require. I went all the way back to
3798 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3799 a seemingly endless set of combinations of versions more recent
3800 than that. The bottom line is that the current sources require
3801 fairly recent versions of the build tools, and it'll be some work
3803 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3804 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3805 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3806 Add comments explaining why those particular versions are
3809 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
3810 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3811 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3813 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work

3828 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3829 * README-alpha: Don't tell people not to package this.
3831 * bootstrap: Don't assume $(...) works; use `...` instead.
3832 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3835 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3836 put into the -d output file, and mention what to do if YYSTYPE is
3839 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3841 Undo change made earlier today: it caused autopoint to not bring
3842 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3845 * bootstrap: Check that gettext version matches what's in
3846 configure.ac. Warn users to ignore robots.txt ERROR 404.
3847 * bootstrap: Undo today's earlier change (logged below).
3848 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3850 The gettext version checking is causing more trouble than it's
3851 curing; remove it. Problem reported by Paul Hilfinger.
3853 * bootstrap: Issue a warning that one can expect a message
3854 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3855 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3857 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3859 Ensure that the C++ compiler used for testing actually works on a
3860 simple test program; if not, skip the C++-related tests. Problem

3885 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3886 lalr1.cc runs afoul of the first, and the last two are no longer
3887 supported by GCC 3.4.0.
3888 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3889 * HACKING: Use ./bootstrap, not "make update" to import foreign files.

3927 * src/.cvsignore: Add *.output.
3929 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3930 gets copied to the output file.
3932 2004-04-28 Paul Eggert <eggert@twinsun.com>
3934 Get files from the gnulib and po repositories, instead of relying
3935 on them being in our CVS. Upgrade to latest versions of gnulib
3938 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3939 * bootstrap: Bootstrap from gnulib and po repositories.
3940 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3941 * README-cvs: Document these changes. Remove version numbers from

3947 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3949 (AC_ISC_POSIX): Remove; we no longer support this
3950 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3951 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3952 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3953 Do not check for C89 headers, except for locale.h which is used
3954 by the Yacc library and must port to K&R hosts.

3968 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3969 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

4005 Remove, as these files are now generated automatically
4006 by bootstrap or automake.

4036 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
4037 case, as stos_ is now used by destructors due to the 2004-02-09

4062 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
4064 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
4065 so that this include file can stand alone.
4066 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h

4068 test whether it can stand alone.
4070 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
4071 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the

4075 the union, because empty unions aren't allowed in C. Caught
4078 2004-04-13 Jim Meyering <jim@meyering.net>
4080 * src/conflicts.c (conflicts_print): Correct format string typo:

4146 2004-03-08 Paul Eggert <eggert@gnu.org>
4148 Add support for hex token numbers. Suggested by Odd Arild Olsen in
4149 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
4151 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor

4154 * src/scan-gram.l (scan_integer): New function.
4156 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
4157 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
4158 handle_action_dollar, handle_action_at, convert_ucn_to_byte):

4179 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
4180 error_start_ when erroneous token are discarded.
4181 (Parser::parse) <yyerrlab1>: Compute the location of the error
4182 token so that it covers all the discarded tokens.
4183 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
4184 it can be called with `%skeleton "lalr1.cc"', and do that.
4186 2004-02-02 Paul Eggert <eggert@twinsun.com>
4188 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
4189 $(top_srcdir)/lib and ../lib. This fixes a bug reported
4190 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
4191 There's no need to mention top_builddir since Automake does that
4193 (INCLUDES): Remove, as Automake says it's obsolescent.
4194 Contents migrated into AM_CPPFLAGS as described above.

4206 resulting parsers are compilable with C++.
4208 2003-12-23 Paul Eggert <eggert@twinsun.com>
4210 * config/depcomp, config/install-sh: Sync with Automake 1.8.
4211 * src/output.c (output_skeleton): Rename local var.
4212 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
4213 Bison tokens, as this runs afoul of the 2003-10-07 change that
4214 disallowed NUL bytes in character constants or string literals.
4216 * tests/local.at: Require Autoconf 2.59's Autotest.
4217 * tests/testsuite.at: Don't include local.at, since we now assume
4218 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
4220 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
4221 multiple inclusion warnings.
4223 2003-12-02 Akim Demaille <akim@epita.fr>

4318 When reducing initial empty rules, Bison parser read an initial
4319 location that is not defined. This results in garbage, and that
4320 affects Bison's own parser. Therefore we need (i) to extend Bison
4321 to support a means to initialize this location, and (ii) to use
4322 this CVS Bison to fix CVS Bison's parser.

4362 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
4363 Also, augment the similarity between lalr1.cc and yacc.c.
4364 Note: the locations of error recovery rules are not correct yet.
4366 * data/lalr1.cc: Comment changes to augment the similarity between
4367 lalr1.cc and yacc.c.
4368 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
4369 (yyerrlab1): Remove, but where it used to be (now the bottom part of
4370 yyerrlab), when hitting EOF, pop the whole stack here instead of
4371 merely falling thru the default error handling mechanism.
4372 (yyerrorlab): New label, with the old contents of YYERROR,
4373 plus the following change: pop the stack of rhs corresponding
4374 to the production that invoked YYERROR. That is how Yacc
4375 behaves (required by POSIX).
4376 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
4379 2003-08-25 Akim Demaille <akim@epita.fr>
4381 Tune local.at so that people can "autom4te -l autotest calc.at -o
4382 calc" for instance, to extract a sub test suite.
4384 * tests/testsuite.at: Move the initialization, Autotest version
4385 requirement, and AT_TESTED invocation into...
4386 * tests/local.at: here.

4399 2003-07-26 Paul Eggert <eggert@twinsun.com>
4401 * data/glr.c (YYASSERT): New macro.
4402 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
4403 yyresolveStates, yyprocessOneStack):
4404 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.

4407 2003-07-25 Paul Eggert <eggert@twinsun.com>
4409 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
4410 for portability to K&R C (after ansi2knr, presumably). See
4411 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
4412 by Frank Heckenbach, though I have omitted the structure-initialization
4413 part of his glr-knr.diff patch since I recall that the Portable
4414 C Compiler didn't require that change.

4504 `How Can I Reset @code{yyparse}', since texinfo does not allow
4505 arbitrary @ in node names.
4507 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
4508 shouldn't be needed according to the gettext 0.12.1 documentation
4509 but which seem to be needed anyway: codeset.m4 glibc21.m4
4510 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

4532 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
4533 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
4534 the tests right now.
4535 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4536 yyerror are declared before use; C99 requires this.
4538 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4540 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
4542 (yyrecoverSyntaxError): Correct the logic for setting and testing
4544 Correct comment on handling EOF.
4545 Allow states with only a default reduction, rather than failing
4546 (I can't quite reconstruct why these were not allowed before).
4548 Fixes to avoid problem that $-N rules in GLR parsers can cause
4549 buffer overruns, corrupting state.
4551 * src/output.c (prepare_rules): Output max_left_semantic_context
4553 * src/reader.h (max_left_semantic_context): New variable declaration.

4568 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4570 * tests/cxx-type.at: Exercise location information; update tests
4571 to differentiate output with and without locations.
4572 Remove forward declarations of yylex and yyerror---caused errors
4573 because default YYLTYPE not yet defined.
4574 Change semantic actions to compute strings, rather than printing
4575 them directly (to test proper passing of semantics values). Change
4576 output to prefix notation and update test data and expected results.
4577 (yylex): Track locations.
4578 (stmtMerge): Return value rather than printing, and include arguments

4591 Rename local vars to avoid warnings.
4592 * tests/glr-regression.at (Improper handling of embedded actions
4593 and $-N in GLR parsers): Remove unused local variable from yylex.
4594 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4595 (void) as arg when not pure, since we now assume C89 when building
4596 Bison. Pacify GCC by using parameter.
4598 2003-06-02 Paul Eggert <eggert@twinsun.com>
4600 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4601 yy::Location::lines, yy::Location::columns): Rename arguments
4602 to avoid shadowing; this removes a warning generated by GCC 3.3.
4604 2003-06-01 Paul Eggert <eggert@twinsun.com>
4606 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4607 to g++, as GCC 3.3 complains if you do it.
4608 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4609 everything that WARNING_CFLAGS has, except omit warnings
4610 not suitable for C++.
4611 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4612 * tests/atlocal.in (CXXFLAGS): New var.
4613 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4615 Fix a GLR parser bug I reported in February; see
4616 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4617 The problem was that GLR parsers did not conform to the C standard,
4618 because actions like { $1 = $2 + $3; } expanded to expressions
4619 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4620 to a local variable. The C standard says that expressions
4621 like (var = f ()) + (var = f ()) have undefined behavior.
4622 Another problem was that GCC sometimes issues warnings that
4623 yyfill and its parameters are unused.
4625 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4627 (yyfill): New function.
4629 (yyuserAction): Change type of yynormal to bool, so that it matches
4630 the new yyfill signature. Mark it as possibly unused.
4633 Follow up on a bug I reported in February, where a Bison-generated
4634 parser can loop. Provide a test case and a fix for yacc.c. I
4635 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4636 The original bug report is in:
4637 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4639 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4640 macro's size was becoming unwieldy.
4641 (yyerrlab): Do not discard an empty lookahead symbol, as this
4642 might destroy garbage.
4643 (yyerrorlab): New label, with the old contents of YYERROR,
4644 plus the following change: pop the stack of rhs corresponding
4645 to the production that invoked YYERROR. That is how Yacc
4646 behaves, and POSIX requires this behavior.
4647 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4648 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4649 Define 'alarm' to do nothing if unistd.h is not available.
4650 Add a new rule "exp: '-' error;" to test the above change to
4651 data/yacc.c. Use 'alarm' to abort any test taking longer than
4652 10 seconds, as it's probably looping.
4653 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4654 Also, the new yacc.c generates two fewer diagnostics for an
4657 2003-05-24 Paul Eggert <eggert@twinsun.com>
4659 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4660 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4661 This fixes a problem reported by John Bowman when the Compaq/HP
4662 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4664 * data/yacc.c (union yyalloc): Likewise.
4665 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4667 Switch from 'int' to 'bool' where that makes sense.
4669 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
4670 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
4671 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
4672 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
4673 Return or accept bool, not int. All callers changed.
4674 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
4675 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

4692 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
4693 lbitset_xor_cmp): Likewise.
4694 * lib/bbitset.h: Include <stdbool.h>.
4695 (struct bitset_vtable): The following members now return bool, not
4696 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
4697 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
4699 * src/conflicts.c (count_rr_conflicts): Likewise.
4700 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
4702 * lib/ebitset.c (ebitset_obstack_init): Likewise.
4703 * lib/lbitset.c (lbitset_obstack_init): Likewise.
4704 * src/getargs.c (debug_flag, defines_flag, locations_flag,
4705 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4706 graph_flag): Likewise.
4707 * src/getargs.h (debug_flag, defines_flag, locations_flag,
4708 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4709 graph_flag): Likewise.

4712 * src/reader.c (start_flag, typed): Likewise.
4713 * src/reader.h (typed): Likewise.
4714 * src/getargs.c (LOCATIONS_OPTION): New constant.
4715 (long_options, getargs): Use it.
4716 * src/lalr.c (build_relations): Use bool, not int.
4717 * src/nullable.c (nullable_compute): Likewise.

4721 * src/output.c (prepare): Use it.
4722 * src/output.c (token_definitions_output,
4723 symbol_destructors_output, symbol_destructors_output): Use string,
4724 not boolean integer, to keep track of whether to output separator.

4726 * src/state.c (state_rule_lookaheads_print): Likewise.
4728 * config/install-sh: Sync from automake 1.7.5.
4730 2003-05-14 Paul Eggert <eggert@twinsun.com>
4732 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4733 semicolon after a grammar declaration, in the interest of possible
4734 future changes to the Bison input language.
4735 Do not allow a stray semicolon at the start of the grammar.
4736 (rhses.1): Allow one or more semicolons after any rule, including
4737 just before "|" as required by POSIX.
4738 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4741 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4743 %parse-param support for lalr1.cc.
4745 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4746 b4_cc_constructor_calls, b4_cc_constructor_call,
4747 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4749 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4750 parse-param arguments.
4751 (yy::b4_parser_class_name): Declare instance variables to
4752 hold parse-param arguments.
4753 * tests/calc.at: s/value/semantic_value/ because value clashes
4754 with a member of yy::b4_parser_class_name. Adjust C++ code
4755 to handle %parse-param. Enable %parse-param test in C++.
4757 2003-05-12 Paul Eggert <eggert@twinsun.com>
4759 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4760 English a bit. Fix fclose typo. Change "const char" to "char
4761 const", and use ANSI C rather than K&R for "main". Suggest
4762 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4763 and suggest yy_switch_to_buffer.
4765 2003-05-05 Paul Eggert <eggert@twinsun.com>
4767 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4768 C89. This avoids a diagnostic on compilers that define __STDC__
4769 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4770 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4772 2003-05-03 Paul Eggert <eggert@twinsun.com>
4774 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
4775 Do not overrun array bounds.
4776 This should fix a bug reported today by Olatunji Oluwabukunmi in
4777 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
4779 2003-04-29 Akim Demaille <akim@epita.fr>
4781 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4782 * src/getargs.c, src/getargs.h: here, as bool, not int.
4783 (nondeterministic_parser): New.
4784 * src/parse-gram.y, src/scan-gram.l: Support
4785 %nondeterministic-parser.
4786 * src/output.c (prepare): Use nondeterministic_parser instead
4787 of glr_parser where appropriate.
4788 * src/tables.c (conflict_row, action_row, save_row)
4789 (token_actions, token_actions, pack_vector): Ditto.
4791 2003-04-29 Akim Demaille <akim@epita.fr>
4793 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4795 2003-04-29 Akim Demaille <akim@epita.fr>
4797 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4798 with %pure-parser and %locations to exercise the patch from Yakov
4801 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4803 * data/yacc.c: (b4_lex_param): Corrected for the case where
4804 %lex-param is provided and %pure-parser isn't.
4806 2003-04-27 Paul Eggert <eggert@twinsun.com>
4808 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4809 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4810 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4811 if it is not defined.
4812 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4814 2003-04-26 Paul Eggert <eggert@twinsun.com>
4816 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4817 Declare to be of type suitable for the ninf value itself, not of
4818 type suitable for the corresponding table, since the latter might
4819 be unsigned but the ninf value might be negative. This fixes a
4820 bug reported by Alexandre Duret-Lutz in
4821 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4823 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4824 invokes it. We shouldn't invoke it twice because it will attempt
4825 to put error.o in the archive twice. This fixes a glitch reported
4826 by Martin Mokrejs in
4827 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4829 2003-04-21 Paul Eggert <eggert@twinsun.com>
4831 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4834 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4836 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4837 Fix obvious typo that results in uncompilable GLR parsers
4838 when both %pure-parser and %locations are used. (trivial change)
4840 2003-04-17 Paul Eggert <eggert@twinsun.com>
4842 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4843 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4844 Do not insert the expected token via unput, as this runs afoul
4845 of a POSIX-compatibility bug in flex 2.5.31.
4846 All uses changed to BEGIN the parent state,
4847 since we no longer insert the expected token via unput.
4848 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4849 that is no longer emitted after the above change.
4851 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4852 the first one. This change is from Paul Hilfinger, and it fixes
4853 regression reported by Werner Lemberg in
4854 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4856 (resolve_sr_conflict): Don't invoke state_errs_set
4857 unless one or more tokens have been explicitly made errors.
4858 Otherwise, the above change causes Bison to abort.
4860 * tests/existing.at (GNU pic Grammar): New test case, taken from
4863 2003-03-31 Akim Demaille <akim@epita.fr>
4865 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4867 2003-03-31 Akim Demaille <akim@epita.fr>
4869 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4872 2003-03-31 Akim Demaille <akim@epita.fr>
4874 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4875 From Paul Hilfinger.
4877 2003-03-29 Akim Demaille <akim@epita.fr>
4879 * m4/error.m4: Do not put under dynamic conditions some code which
4880 expansion is under static control.
4882 2003-03-29 Akim Demaille <akim@epita.fr>
4884 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4886 2003-03-29 Akim Demaille <akim@epita.fr>
4888 * doc/bison.texinfo (Strings are Destroyed): New.
4890 2003-03-13 Paul Eggert <eggert@twinsun.com>
4892 * .cvsignore: Add configure.lineno.
4893 * src/.cvsignore: Add yacc.
4894 * tests/.cvsignore: Add testsuite.log.
4895 * doc/fdl.texi: Sync with latest FSF version.
4897 2003-03-12 Paul Eggert <eggert@twinsun.com>
4899 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4900 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4901 cursor, instead of leaving it undefined. This fixes a bug
4902 reported by Tim Van Holder in
4903 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4904 * tests/input.at (Torturing the Scanner): Test the scanner on
4905 an empty input file, which was Tim Van Holder's test case.
4907 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4908 <sys/resource.h> can be included, include sys/time.h and
4909 sys/times.h first, if available. This works around the SunOS
4910 4.1.4 porting bug reported by Bruce Becker in
4911 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4913 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4914 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4917 Merge changes from gnulib. This was prompted because the CVS
4918 snapshot didn't build on Solaris 7 due to strnlen problems.
4920 These changes need to be merged back into gnulib:
4921 * lib/hash.c: Include <stdbool.h> unconditionally.
4922 * m4/onceonly.m4 (m4_quote): New macro.
4923 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4924 Quote AC_FOREACH variable-expansions properly.
4925 The 2003-01-03 obstack.h change also needs merging.
4926 {end of changes requiring merging}
4928 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
4929 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
4930 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
4931 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
4932 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
4933 New files, imported from gnulib.
4934 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
4937 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
4938 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
4941 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
4943 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
4944 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
4945 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
4946 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
4947 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
4948 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
4949 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
4950 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
4951 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
4952 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
4953 (jm_PREREQ_ARGMATCH): Remove.
4954 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
4955 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
4957 * src/system.h: Include <stdbool.h> unconditionally.
4959 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
4960 assuming at least C89 in the bitset code for some time now.
4962 2003-03-03 Akim Demaille <akim@epita.fr>
4966 2003-03-02 Akim Demaille <akim@epita.fr>
4968 * doc/bison.texinfo (Table of Symbols): Reactivate the
4969 documentation for %lex-param, and %parse-param.
4971 2003-03-02 Akim Demaille <akim@epita.fr>
4973 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4974 generate verbose error messages.
4975 Use the number of tokens as an upper bound in yytname, as it
4976 cannot be a non terminal.
4978 2003-03-02 Akim Demaille <akim@epita.fr>
4980 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4983 2003-03-02 Akim Demaille <akim@epita.fr>
4985 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
4986 Use them to exercise yycheck overrun.
4987 Based on Andrew Suffield's grammar.
4989 2003-03-02 Akim Demaille <akim@epita.fr>
4991 Create tests/local.at for Bison generic testing macros.
4993 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
4994 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
4996 * tests/calc.at (AT_CHECK_CALC): Adjust.
4997 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
4998 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
4999 * tests/local.at: here.
5000 (AT_COMPILE_CXX): Tags the tests using it as c++.
5001 Ignore the test if CXX is not functional.
5003 2003-03-01 Paul Eggert <eggert@twinsun.com>
5005 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
5006 not loc->end, since loc->end might contain garbage and this leads
5007 to undefined behavior on some platforms.
5008 (id_loc, token_start): Use (IF_LINTed) initial values that do not
5009 depend on *loc, so that the reader doesn't give the the false
5010 impression that *loc is initialized.
5011 (<INITIAL>"%%"): Do not bother setting code_start, since its value
5012 does not survive the return.
5014 2003-03-01 Akim Demaille <akim@epita.fr>
5016 * src/scan-gram.l (code_start): Always initialize it when entering
5017 into yylex, as SC_EPILOGUE is activated *before* the corresponding
5018 yylex invocation. An alternative would be making it static, but
5019 then it starts with the second %%'s beginning, instead of its end.
5021 2003-02-28 Paul Eggert <eggert@twinsun.com>
5023 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
5024 around a UnixWare 7.1.1 porting bug reported by John Hughes in
5025 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
5027 2003-02-26 Paul Eggert <eggert@twinsun.com>
5029 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
5030 Remove Sequent/Pyramid discussion (nobody uses them any more).
5031 Merge VMS and MS-DOS discussion; these ports may well be dead
5032 but let's keep mentioning them for now. Put <> around email
5033 addresses. Add copyright notice.
5035 2003-02-24 Paul Eggert <eggert@twinsun.com>
5037 * data/glr.c (yy_reduce_print): yylineno -> yylno,
5038 to avoid collision with flex use of yylineno.
5039 Problem reported by Bruce Lilly in
5040 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
5041 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
5042 * data/yacc.c (yy_reduce_print): Likewise.
5044 * config/depcomp: Sync with Automake 1.7.3.
5046 2003-02-21 Akim Demaille <akim@epita.fr>
5048 * data/lalr1.cc: Use temporary variables instead of casts to
5049 change integer types.
5050 Suggested by Paul Eggert.
5052 2003-02-21 Akim Demaille <akim@epita.fr>
5054 * doc/bison.texinfo: Use "location" consistently to refer to @n,
5055 to avoid confusions with lalr1.cc's notion of Position.
5056 Suggested by Paul Eggert.
5058 2003-02-20 Akim Demaille <akim@epita.fr>
5060 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
5061 before initial_columns.
5062 (location.hh): Use consistent variable names when defining the
5064 Use "last" so that we subtract from Positions, not from unsigned.
5066 2003-02-20 Akim Demaille <akim@epita.fr>
5068 * data/lalr1.cc (position.hh): New subfile, including the extended
5069 and Doxygen'ed documentation of class Position.
5070 (location.hh): Use it.
5071 Document a` la Doxygen.
5072 With the help of Benoit Perrot.
5074 2003-02-20 Akim Demaille <akim@epita.fr>
5076 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
5078 Redefine AT_YYERROR_SEES_LOC_IF using it.
5079 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
5081 Don't use the location in yy::Parser::error_ and
5082 yy::Parser::print_ when not %locations.
5083 Activate more lalr1.cc tests.
5085 2003-02-19 Akim Demaille <akim@epita.fr>
5087 * data/lalr1.cc: When displaying a line number, be sure to make it
5090 2003-02-19 Akim Demaille <akim@epita.fr>
5092 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
5094 (YYABORT, YYACCEPT, YYERROR): New.
5095 * tests/calc.at: Renable the lalr1.cc test.
5097 2003-02-19 Akim Demaille <akim@epita.fr>
5099 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
5100 error recovery, mixing with/without pops and discarding of the
5103 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
5105 2003-02-17 Paul Eggert <eggert@twinsun.com>
5107 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
5108 * tests/testsuite.at (AT_COMPILE): Use them.
5109 This fixes the testsuite problem reported by Robert Lentz in
5110 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
5112 2003-02-12 Paul Eggert <eggert@twinsun.com>
5114 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
5115 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
5116 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
5117 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
5118 Check for malloc failure, for consistency with yacc.c.
5119 (yytname_size): Remove, for consistency with yacc.c.
5121 The bug still remains in data/lalr1.cc, as I didn't have time
5124 2003-02-06 Akim Demaille <akim@epita.fr>
5126 * configure.ac (GXX): Rename as...
5127 (CXX): this, to keep the original Autoconf semantics.
5129 * data/lalr1.cc: Fix b4_copyright invocations.
5130 If YYDEBUG is not defined, don't depend upon name_ being defined.
5131 (location.hh): Include string and iostream.
5132 (Position::filename): New member.
5133 (Position::Position ()): New.
5134 (operator<< (Position)): New.
5135 (operator- (Position, int)): New.
5136 (Location::first, Location::last): Rename as...
5137 (Location::begin, Location::end): these, to mock the conventional
5139 (operator<< (Location)): New.
5140 * tests/atlocal.in (CXX): New.
5141 * tests/testsuite.at (AT_COMPILE_CXX): New.
5142 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
5143 locations in a more synthetic way.
5144 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
5146 Adjust the C locations to match those from Emacs: first column is
5148 Change all the expected results.
5149 Conform to the GCS: simplify the locations when applicable.
5150 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
5151 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
5152 these CPP macros with the m4 macros new defined by...
5153 (AT_CHECK_PUSHDEFS): this, i.e.:
5154 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
5155 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
5157 (AT_CHECK_POPDEFS): Undefine them.
5158 (AT_CHECK_CALC_LALR1_CC): New.
5159 Use it for the first lalr1.cc test.
5161 2003-02-04 Akim Demaille <akim@epita.fr>
5163 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
5164 Location as is defined.
5166 2003-02-04 Akim Demaille <akim@epita.fr>
5168 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
5169 name_ being defined.
5171 2003-02-03 Paul Eggert <eggert@twinsun.com>
5173 * src/gram.h (start_symbol): Remove unused decl.
5175 Use more-consistent naming conventions for local vars.
5177 * src/derives.c (derives_compute): Change type of local var from
5179 * src/gram.c (grammar_rules_partial_print): Likewise.
5180 * src/print.c (print_core): Likewise.
5181 * src/reduce.c (reduce_grammar_tables): Likewise.
5183 * src/gram.c (grammar_dump): Change name of item_number *
5184 local var from r to rp.
5185 * src/nullable.c (nullable_compute): Likewise.
5187 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
5189 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
5190 for symbol or symbol_number var.
5191 * src/reader.c (grammar_start_symbol_set): Likewise.
5192 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
5194 * src/state.c (transitions_to): Likewise.
5195 * src/state.h: Likewise.
5196 * src/tables.c (symbol_number_to_vector_number): Likewise.
5198 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
5201 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
5204 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
5207 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
5208 Use str, not s, for char * var. Use ch, not c, for character var.
5209 Use size for size var.
5211 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
5213 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
5215 * src/uniqstr.h: Likewise.
5217 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
5218 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
5219 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
5220 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
5221 param to have same name as that of enum, so that we don't use
5222 "s" to stand for a non-state.
5224 2003-02-02 Akim Demaille <akim@epita.fr>
5226 * src/scan-skel.l: Scan more than one inert character per yylex
5229 2003-02-01 Paul Eggert <eggert@twinsun.com>
5233 * po/LINGUAS: Add ms.
5235 2003-01-30 Akim Demaille <akim@epita.fr>
5237 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
5239 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5241 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
5244 Changes in response to error report by S. Eken: GLR mode does not
5245 handle negative $ indices or $ indices in embedded rules correctly.
5246 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
5248 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
5249 (b4_rhs_location): Ditto.
5250 (yyfill): New function to copy from stack tree into array
5252 (yyuserAction): Modify to allow incremental move of semantic values
5253 to rhs array when in GLR mode.
5254 Define YYFILL to use in user-defined actions to fill semantic array
5256 Remove dummy use of yystack, as there is now a guaranteed use.
5257 (yydoAction): Modify to allow incremental move of semantic values
5258 to rhs array when in GLR mode.
5259 (yyresolveAction): Ditto.
5260 (yyglrShiftDefer): Update comment.
5261 (yyresolveStates): Use X == NULL for pointers, not !X.
5262 (yyglrReduce): Ditto.
5265 * tests/glr-regr1.at: Rename to ...
5266 * tests/glr-regression.at: Add new regression test for the problems
5267 described above (adapted from S. Eken).
5268 Update copyright notice.
5269 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
5270 * tests/Makefile.am: Ditto.
5272 2003-01-28 Paul Eggert <eggert@twinsun.com>
5274 * data/lalr1.cc: Do not use @output_header_name@ unless
5275 b4_defines_flag is set. This fixes two bugs reported by
5277 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
5278 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
5280 2003-01-21 Paul Eggert <eggert@twinsun.com>
5282 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
5283 we don't need to worry about yyerrlab1 being reported as an
5284 "unused label" by non-GCC C compilers. The downside is that if
5285 locations are used then a couple of statements are duplicated each
5286 time YYERROR is invoked, but the upside is that the warnings
5288 (yyerrlab1): Move code to YERROR.
5289 (yyerrlab2): Remove. Change uses back to yyerrlab1.
5290 This reverts some of the 2002-12-27 change.
5292 2003-01-17 Paul Eggert <eggert@twinsun.com>
5294 * src/output.c (symbol_printers_output): Fix typo that led
5295 to core dump. Problem reported by Antonio Rus in
5296 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
5298 2003-01-13 Akim Demaille <akim@epita.fr>,
5299 Quoc Peyrot <chojin@lrde.epita.fr>,
5300 Robert Anisko <anisko_r@lrde.epita.fr>
5302 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
5303 when the stacks contain one element, as the loop would otherwise
5304 free the last state, and then use the top state (the one we just
5305 popped). This means that the initial elements will not be freed
5306 explicitly, as is the case in yacc.c; it is not a problem, as
5307 these elements have fake values.
5309 2003-01-11 Paul Eggert <eggert@twinsun.com>
5311 * NEWS: %expect-violations are now just warnings, reverting
5312 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
5313 bootstrapping problem reported by Matthias Klose; see
5314 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
5315 * src/conflicts.c (conflicts_print): Likewise.
5316 * tests/conflicts.at (%expect not enough, %expect too much,
5317 %expect with reduce conflicts): Likewise.
5318 * doc/bison.texinfo (Expect Decl): Document this. Also mention
5319 that the warning is enabled if the number of conflicts changes
5320 (not necessarily increases).
5322 * src/getargs.c (version): Update copyright year.
5324 2003-01-09 Akim Demaille <akim@epita.fr>
5326 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
5328 2003-01-08 Paul Eggert <eggert@twinsun.com>
5330 * Makefile.maint (WGETFLAGS):
5331 New macro, containing "-C off" to disable proxy caches.
5332 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
5333 (rel-check): Use $(WGET) instead of wget.
5335 2003-01-06 Paul Eggert <eggert@twinsun.com>
5337 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
5338 the GLR paper of Scott, Johnstone and Hussain.
5340 2003-01-04 Paul Eggert <eggert@twinsun.com>
5342 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
5343 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
5344 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
5345 (EXTRA_LIBRARIES): New var, for liby.a.
5346 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
5347 (EXTRA_SCRIPTS): New var, for yacc.
5349 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
5350 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
5351 Problem reported by Nelson H. F. Beebe.
5353 2003-01-03 Paul Eggert <eggert@twinsun.com>
5355 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
5356 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
5357 when compiling Bison 1.875's `bitset bset = obstack_alloc
5358 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
5360 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
5361 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
5362 grow to a huge size with typical invocation.
5364 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
5365 Use the pattern recommended by Autoconf 2.57, except also protect
5366 against double-definition.
5367 * src/system.h: Likewise.
5368 Portability issues reported by Nelson H. F. Beebe.
5370 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
5371 All uses changed. Provide a definition in both C and C++.
5372 (yytrue, yyfalse): Define even if defined (__cplusplus).
5374 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
5375 Reported by Nelson H. F. Beebe.
5377 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
5379 2003-01-02 Paul Eggert <eggert@twinsun.com>
5381 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
5382 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
5383 Bug reported by Nelson H. F. Beebe.
5385 2003-01-01 Paul Eggert <eggert@twinsun.com>
5389 2002-12-30 Paul Eggert <eggert@twinsun.com>
5391 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
5393 (<INITIAL>","): Here. This causes stray "," to be treated
5396 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
5397 last brace in braced code when not in Yacc mode, for compatibility
5398 with Bison 1.35. This resurrects the 2001-12-15 patch to
5401 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
5402 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
5404 2002-12-28 Paul Eggert <eggert@twinsun.com>
5406 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
5407 that of SYM's type. This fixes Debian bug 168069, reported by
5410 2002-12-28 Paul Eggert <eggert@twinsun.com>
5414 Switch back to the Yacc style of conflict reports, undoing some
5415 of the 2002-07-30 change.
5416 * doc/bison.texinfo (Understanding): Use Yacc style for
5417 conflict reports. Also, use new way of locating rules.
5418 * src/conflicts.c (conflict_report):
5419 Renamed from conflict_report_yacc, removing the old
5420 'conflict_report'. Translate the entire conflict report at once,
5421 so that we don't assume that "," has the same interpretation in
5423 (conflicts_output): Use Yacc-style conflict report for each state,
5424 instead of our more-complicated style.
5425 (conflicts_print): Use Yacc-style conflict report, except print
5426 the input file name when not emulating Yacc.
5427 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5428 Conflicted Reduction, %expect not enough, %expect too much,
5429 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
5430 * tests/existing.at (GNU Cim Grammar): Likewise.
5431 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
5433 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
5434 fatal): Don't invoke fflush; it's not needed and it might even be
5435 harmful for stdout, as stdout might not be open.
5436 * src/reduce.c (reduce_print): Likewise.
5438 2002-12-27 Paul Eggert <eggert@twinsun.com>
5440 Fix a bug where error locations were not being recorded correctly.
5441 This problem was originally reported by Paul Hilfinger in
5442 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
5444 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5445 top of the location stack's error locations.
5446 (yyerrlab): Set it. When discarding a token, push its location
5447 onto yylerrsp so that we don't lose track of the error's end.
5448 (yyerrlab1): Now is only the target of YYERROR, so that we can
5449 properly record the location of the action that failed. For GCC
5450 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5451 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5452 (yyerrlab2): New label, which yyerrlab now falls through to.
5453 Compute the error's location by applying YYLLOC_DEFAULT to
5454 the locations of all the symbols that went into the error.
5455 * doc/bison.texinfo (Location Default Action): Mention that
5456 YYLLOC_DEFAULT is also invoked for syntax errors.
5457 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5458 Error locations include the locations of all the tokens that were
5459 discarded, not just the last token.
5461 2002-12-26 Paul Eggert <eggert@twinsun.com>
5463 * src/files.c: Include quote.h.
5464 (compute_output_file_names): Warn if we detect conflicting
5465 outputs to the same file. This should catch the misunderstanding
5466 exemplified by Debian Bug 165349, reported by Bruce Stephens..
5468 * src/conflicts.c (conflicts_print): If the user specifies
5469 "%expect N", report an error if there are any reduce/reduce
5470 conflicts. This is what the manual says should happen.
5471 This fixes Debian bug 130890, reported by Anthony DeRobertis.
5472 * tests/conflicts.at (%expect with reduce conflicts): New test.
5474 Don't use m4_include on relative file names, as it doesn't work as
5475 desired if there happens to be a file with that name under ".".
5477 * m4sugar/version.m4: Remove; it was included but it wasn't used.
5478 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
5479 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
5480 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
5481 * src/output.c (output_skeleton): Use full path names when
5482 specifying a file to include; don't rely on include path, as
5483 it's unreliable when the working file contains a file with
5486 2002-12-25 Paul Eggert <eggert@twinsun.com>
5488 Remove obsolete references to bison.simple and bison.hairy.
5489 Problem mentioned by Aubin Mahe in
5490 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
5491 * data/glr.c: Comment fix.
5492 * doc/bison.1: Remove references. Also, mention "yacc".
5494 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
5497 * src/parse-gram.y (declaration): Use enum "report_states" rather
5498 than its numeric value 1.
5500 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
5501 opening a new one. This fixes Debian bug 165349, reported by
5504 2002-12-24 Paul Eggert <eggert@twinsun.com>
5508 * Makefile.maint (cvs-update): Don't assume that the shell
5509 supports $(...), as Solaris sh doesn't.
5511 * src/parse-gram.y (lloc_default): Remove test for empty
5512 nonterminals at the end, since it didn't change the result.
5514 2002-12-24 Paul Eggert <eggert@twinsun.com>
5516 If the user does not define YYSTYPE as a macro, Bison now declares it
5517 using typedef instead of defining it as a macro. POSIX requires this.
5518 For consistency, YYLTYPE is also declared instead of defined.
5520 %union directives can now have a tag before the `{', e.g., the
5521 directive `%union foo {...}' now generates the C code
5522 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5523 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5524 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5525 instead of `yyltype'.
5527 `yystype' and `yyltype' are now obsolescent macros instead of being
5528 typedefs or tags; they are no longer documented and will be
5529 withdrawn in a future release.
5531 * data/glr.c (b4_location_type): Remove.
5532 (YYSTYPE): Renamed from yystype.
5533 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5534 (struct YYLTYPE): Renamed from struct yyltype.
5535 (YYLTYPE): Renamed from yyltype.
5536 (yyltype, yystype): New (and obsolescent) macros,
5537 for backward compatibility.
5538 * data/yacc.c: Likewise.
5540 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5541 does not specify a union tag. This is for compatibility with
5544 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5545 const *, since it is now modified by stripping surrounding { }.
5546 (current_braced_code): Remove.
5547 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5548 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5549 trailing " {...}". Now of type <chars>.
5550 (grammar_declaration): Adjust to bundled tokens.
5551 (code_content): Remove; stripping is now done by add_param.
5552 (print_token_value): Print contents of bundled tokens.
5553 (token_name): New function.
5555 * src/reader.h (braced_code, current_braced_code): Remove.
5556 (token_name): New decl.
5558 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5559 token_type, not braced_code code_kind. All uses changed.
5560 (SC_PRE_CODE): New state, for scanning after a keyword that
5561 has (or usually has) an immediately-following braced code.
5562 (token_type): New local var, to keep track of which token type
5563 to return when scanning braced code.
5564 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5565 <INITIAL>"%parse-param", <INITIAL>"%printer",
5566 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5567 instead of returning a token type immediately.
5568 (<INITIAL>"{"): Set token type.
5569 (<SC_BRACED_CODE>"}"): Use it.
5570 (handle_action_dollar, handle_action_at): Now returns bool
5571 indicating success. Fail if ! current_rule; this prevents a core dump.
5572 (handle_symbol_code_dollar, handle_symbol_code_at):
5573 Remove; merge body into caller.
5574 (handle_dollar, handle_at): Complain in invalid contexts.
5576 * NEWS, doc/bison.texinfo: Document the above.
5577 * NEWS: Fix years and program names in copyright notice.
5579 2002-12-17 Paul Eggert <eggert@twinsun.com>
5581 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5582 Reporting, Table of Symbols): Omit mentions of %lex-param and
5583 %parse-param from the documentation for now.
5585 2002-12-15 Paul Eggert <eggert@twinsun.com>
5587 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5588 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5589 lookahead symbol, and which sets yychar in parser actions) and it
5590 disagreed with the Bison documentation. Bug
5591 reported by Andrew Walrond.
5593 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5594 as the caller now does that.
5595 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5596 (YYEMPTY): Parenthesize right hand side, since others use it.
5597 (yyparse): Don't assume that our generated code is the only code
5600 2002-12-13 Paul Eggert <eggert@twinsun.com>
5604 POSIX requires a "yacc" command.
5605 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
5606 (MOSTLYCLEANFILES): Add yacc.
5608 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
5609 as an alias for bison y.
5611 * po/LINGUAS: Add da.
5613 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
5614 problem with latest <getopt.h>.
5615 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
5617 * doc/fdl.texi: Upgrade to 1.2.
5618 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
5619 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
5620 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
5622 * config/install-sh: Sync with autotools.
5624 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
5625 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5626 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
5627 locations are requested.
5628 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
5629 locations are requested.

5633 Remove unportable casts and storage allocation tricks.
5634 While we're at it, remove almost all casts, since they
5635 usually aren't needed and are a sign of trouble.
5637 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5639 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5640 the pointer DSET returned by malloc; this isn't portable.
5641 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
5642 Similarly for DERIVES.
5643 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
5644 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
5645 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
5647 * src/derives.c (derives_compute): Do not bother invoking
5648 int_of_rule_number, since rule numbers are integers.

5651 rather than XMALLOC (char, N).
5653 * src/files.c (filename_split): Rewrite to avoid cast.
5655 * src/gram.h (symbol_number_as_item_number,
5656 item_number_as_symbol_number, rule_number_as_item_number,
5657 item_number_as_rule_number):
5658 Now inline functions rather than macros, to avoid casts.
5659 * src/state.h (state_number_as_int): Likewise.
5660 * src/tables.c (state_number_to_vector_number,
5661 symbol_number_to_vector_number): Likewise.
5663 * src/gram.h (int_of_rule_number): Remove; no longer used.
5665 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
5666 since the resulting storage is always stored into.
5668 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
5671 * src/muscle_tab.c (muscle_m4_output):
5672 Now inline. Return bool, not int.
5673 * src/state.c (state_compare): Likewise.

5683 symbol_check_alias_consistency_processor, symbol_pack_processor,
5684 symbol_translation_processor, hash_symbol_comparator,
5685 hash_symbol_hasher): Likewise.
5686 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5687 * src/muscle_tab.c (muscles_m4_output):
5688 Use new functions instead of casting old functions unportably.
5689 * src/state.c (state_hash_new): Likewise.
5690 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5691 symbols_token_translations_init):
5693 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5695 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5696 var instead of casting to long, to avoid casts.
5697 (prepare_states): Use MALLOC rather than alloca, so that we don't
5698 have to worry about alloca.
5699 * src/state.c (state_hash_lookup): Likewise.
5701 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5702 local var instead of casting to unsigned char, to avoid casts.

5705 STATE_ALLOC): Remove.
5706 (transitions_new, errs_new, reductions_new, state_new): Use malloc
5707 rather than calloc, and use offsetof to avoid allocating slightly
5709 (state_new): Initialize all members.
5711 * src/state.c (state_hash): Use unsigned accumulator, not signed.
5713 * src/symtab.c (symbol_free): Remove; unused.
5714 (symbol_get): Remove cast in lhs of assignment.
5715 (symbols_do): Now static. Accept generic arguments, not
5716 hashing-related ones.
5718 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
5719 (symbol_processor): Remove.
5720 (symbols_do): Remove decl; now static.
5722 * src/system.h (alloca): Remove; decl no longer needed.
5723 (<stddef.h>): Include, for offsetof.
5724 (<inttypes.>, <stdint.h>): Include if available.
5725 (uintptr_t): New type, if system lacks it.
5726 (CALLOC, MALLOC, REALLOC): New macros.
5727 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5730 * src/tables.c (table_size): Now int, to pacify GCC.
5731 (table_grow, table_ninf_remap): Use signed table size.
5732 (save_row): Don't bother initializing locals when not needed.
5733 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
5734 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
5736 * src/vcg.h: Correct misspellings.
5738 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
5741 * src/getargs.c (getargs): Don't assume EOF == -1.
5743 2002-12-09 Paul Eggert <eggert@twinsun.com>
5745 Change identifier spellings to avoid collisions with names
5746 that are reserved by POSIX.
5748 Don't use names ending in _t, since POSIX reserves them.
5749 For consistency, remove _e and _s endings -- they're weren't
5750 needed to remove ambiguity. All uses changed.
5751 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5752 turn was just renamed from struniq_t.
5753 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
5754 which in turn was just renamed from struniq_processor_t.
5755 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

5825 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
5826 value_t_as_yystype -> value_as_yystype.
5828 Don't include <errno.h> in the mainstream code, since it
5829 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5830 * lib/get-errno.c, lib/get-errno.h: New files.
5831 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
5833 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

5839 (handle_action_dollar, handle_action_at): Likewise.
5840 * src/system.h: Do not include <errno.h>.
5841 (TAB_EXT): Renamed from EXT_TAB.
5842 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
5844 Avoid str[a-z]*, since <string.h> reserves that name space.
5845 Change all instances of "struniq" in names to "uniqstr", and
5846 likewise for "STRUNIQ" and "UNIQSTR".
5847 * src/uniqstr.c: Renamed from src/struniq.c.
5848 * src/uniqstr.h: Renamed from src/struniq.h.
5849 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

5859 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
5860 (N_EXPAND): Renamed from N_STRETCH.

5863 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
5864 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

5871 (BASE_MINIMUM): Renamed from BASE_MIN.
5872 (ACTION_MAX): Remove; unused.
5873 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
5874 Unnecessary casts removed from above defines.

5878 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
5879 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
5883 * lib/timevar.c (timevar_report): Renamed from time_report,
5884 for consistency with other names.
5885 * lib/timevar.h (timevar_report): New decl.
5886 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5889 Sort include-file uses.
5891 Reorder all include files under src to be in the order "system.h".
5892 then the ../lib include files in angle brackets (alphabetized),
5893 then the . include files in double-quotes (alphabetized). Fix
5894 dependency breakages encountered in this process, as follows:
5895 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5896 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5897 * src/state.h: Include "symtab.h".
5899 2002-12-08 Paul Eggert <eggert@twinsun.com>
5901 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5902 since this causes problems when __file__ contains character
5903 sequences like "@" that are treated specially by src/scan-skel.l.
5904 Instead, just use the file's basename. This fixes the bug
5905 reported by Martin Mokrejs in
5906 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5908 2002-12-06 Paul Eggert <eggert@twinsun.com>
5910 Add support for rules that do not have trailing semicolons, as
5911 POSIX requires. Improve the quality of locations in Bison
5914 * src/location.c: Include <quotearg.h>.
5915 (empty_location): Now const.
5916 (location_print): New function. Follow the recommendation of the
5917 GNU Coding Standards for locations that span file boundaries.
5918 * src/location.h: Do not include <quotearg.h>; no longer needed.
5919 (boundary): New type.
5920 (location_t): Use it. This allows locations to span file boundaries.
5921 All member uses changed: file -> start.file or end.file (as needed),
5922 first_line -> start.line, first_column -> start.column,
5923 last_line -> end.line, last_column -> end.column.
5924 (equal_boundaries): New function.
5925 (LOCATION_RESET, LOCATION_STEP): Remove.
5926 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5927 (empty_location): Now const.
5928 (location_print): New decl.
5929 * src/parse-gram.y (lloc_default): New function, which handles
5930 empty locations more accurately.
5931 (YYLLOC_DEFAULT): Use it.
5932 (%token COLON): Remove.
5933 (%token ID_COLON): New token.
5935 (declarations, rules): Remove trailing semicolon.
5936 (declaration, rules_or_grammar_declaration):
5937 Allow empty (";") declaration.
5938 (symbol_def): Remove empty actions; no longer needed.
5939 (rules_or_grammar_declaration): Remove trailing semicolon.
5940 (semi_colon.opt): Remove.
5941 * src/reader.h: Include location.h.
5942 (scanner_cursor): New decl.
5943 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
5945 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
5947 (STEP): Remove. No longer needed, now that adjust_location does
5948 the work. All uses removed.
5949 (scanner_cursor): New var.
5950 (adjust_location): Renamed from extend_location. It now sets
5951 *loc and adjusts the scanner cursor. All uses changed.
5952 Don't bother testing for CR.
5953 (handle_syncline): Remove location arg; now updates scanner cursor.
5954 All callers changed.
5955 (unexpected_end_of_file): Now accepts start boundary of token or
5956 comment, not location. All callers changed. Update scanner cursor,
5958 (SC_AFTER_IDENTIFIER): New state.
5959 (context_state): Renamed from c_context. All uses changed.
5960 (id_loc, code_start, token_start): New local vars.
5961 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5962 processing of Yacc white space and equivalents here.
5963 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5964 instead of returning ID immediately, since we need to search for
5966 (<INITIAL>"'", "\""): Save token_start.
5967 (<INITIAL>"%{", "{", "%%"): Save code_start.
5968 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5969 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5970 BEGIN context_state at end, not INITIAL.
5971 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5972 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5973 Return correct token start.
5974 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5975 the start of a character, string or multiline comment is found.
5976 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5977 Reduction): Adjust reported locations to match the more-precise
5978 results now expected.
5979 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5980 * tests/reduce.at (Useless Rules, Reduced Automaton,
5981 Underivable Rules): Likewise.
5982 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5983 or "|"' now that so many other tokens are allowed by the new grammar.
5985 * src/complain.h (current_file): Remove duplicate decl;
5986 current_file is now owned by files.h.
5987 * src/complain.c, src/scan-gram.l: Include files.h.
5989 2002-12-06 Paul Eggert <eggert@twinsun.com>
5991 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
5992 promotes to int; it might be unsigned int.
5993 * data/yacc.c (yy_reduce_print): Likewise.
5995 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
5996 be #defined in the prologue, not in the Bison declarations.
5997 This fixes Debian Bug 102878, reported by Shaul Karl.
5999 2002-12-02 Paul Eggert <eggert@twinsun.com>
6001 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
6002 * lib/strtoul.c: New file, from gnulib.
6003 This fixes a porting bug reported by Peter Klein in
6004 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
6006 2002-11-30 Paul Eggert <eggert@twinsun.com>
6008 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
6009 and put only a forward declaration in the prologue. This is for
6010 consistency with the other scanner helper functions.
6012 Type clashes now generate warnings, not errors, since it
6013 appears that POSIX may allow some grammars with type clashes.
6014 * src/reader.c (grammar_current_rule_check): Warn about
6015 type clashes instead of complaining.
6016 * tests/input.at (Type Clashes): Expect warnings, not complaints.
6018 Add Yacc library, since POSIX requires it.
6019 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
6020 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
6021 * lib/main.c, lib/yyerror.c: New files.
6023 gram_error can be static; it need not be extern.
6024 * src/reader.h (gram_error): Remove decl.
6025 * src/parse-gram.y (gram_error): Now static. Add static decl.
6026 (print_token_value): Omit parameter names from forward decl,
6029 2002-11-29 Paul Eggert <eggert@twinsun.com>
6031 * doc/bison.texinfo: Emphasize that yylex and yyerror must
6032 be declared before being used. E.g., one should typically
6033 declare them in the prologue. Use GNU coding style in examples.
6034 Put "const" consistently after the type it modifies. Mention
6035 that C99 supports "inline". Mention that yyerror traditionally
6038 %parse-param and %lex-param now take just one argument, the
6039 declaration; the argument name is deduced from the declaration.
6041 * doc/bison.texinfo (Parser Function, Pure Calling, Error
6042 Reporting, Table of Symbols): Document this.
6043 * src/parse-gram.y (add_param): New function.
6045 (declaration): Implement new rule for %parse-param and %lex-param.
6046 * src/scan-gram.l: "," now elicits a warning, rather than being
6047 a token; this is more compatible with byacc.
6048 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
6050 2002-11-27 Paul Eggert <eggert@twinsun.com>
6052 Rename identifiers to avoid real and potential collisions.
6054 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
6055 to avoid collision with lex macro described by Bruce Lilly in
6056 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
6057 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
6058 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
6059 * src/parse-gram.y (print_token_value): Renamed from yyprint.
6061 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
6062 The name "yycontrol" violates the name space rules, and this stuff
6063 wasn't being used anyway.
6064 (input): Remove action; this stuff wasn't being used.
6065 (gram_error): Rename local variable yylloc -> loc.
6066 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
6067 (YY_DECL): Don't use "yy" at start of local variables.
6068 All uses changed, e.g., yylloc -> loc.
6069 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
6070 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
6071 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
6072 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
6074 * src/parse-gram.y (gram_error): loc is now const *.
6075 * src/reader.h (gram_error): Likewise.
6077 2002-11-24 Paul Eggert <eggert@twinsun.com>
6081 * tests/actions.at (Actions after errors): Use an output format
6082 more similar to that of the Printers and Destructors test.
6083 Test the position of the ';' token too.
6084 (Printers and Destructors): Likewise.
6085 (Printers and Destructors: %glr-parser): Remove for now, to avoid
6086 unnecessarily alarming people when the test fails.
6088 * data/yacc.c (yyerrlab1): Move this label down, so that the
6089 parser does not discard the lookahead token if the user code
6090 invokes YYERROR. This change is required for POSIX conformance.
6092 * lib/error.c: Sync with gnulib.
6094 2002-11-22 Paul Eggert <eggert@twinsun.com>
6096 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

6100 2002-11-20 Paul Eggert <eggert@twinsun.com>
6102 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
6104 2002-11-20 Paul Eggert <eggert@twinsun.com>
6106 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
6107 should use `if (! x) abort ();' rather than `assert (x);', and
6108 anyway it's one less thing to worry about configuring.
6110 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
6111 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
6112 and replace all instances of assert with abort.
6113 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
6114 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
6116 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
6117 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
6118 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
6119 hash_find_entry, hash_rehash, hash_insert): Likewise.
6120 * src/conflicts.c (resolve_sr_conflict): Likewise.
6121 * src/lalr.c (set_goto_map, map_goto): Likewise.
6122 * src/nullable.c (nullable_compute): Likewise.

6128 symbol_pack): Likewise.
6129 * src/tables.c (conflict_row, pack_vector): Likewise.
6130 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,

6132 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
6133 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
6135 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
6136 (ARGMATCH_CONSTRAINT): New macro.
6137 (ARGMATCH_ASSERT): Use it.
6139 * src/system.h (verify): New macro.
6140 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
6142 * src/tables.c (tables_generate): Likewise.
6144 * src/struniq.c (struniq_assert): Now returns void, and aborts
6145 if the assertion is false.
6146 (struniq_assert_p): Remove.
6147 * src/struniq.h: Likewise.
6149 2002-11-18 Paul Eggert <eggert@twinsun.com>
6151 * data/glr.c (yygetLRActions): Replace `yyindex' with
6152 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
6153 This fixes the regression with Sun ONE Studio 7 cc that I reported in
6154 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
6156 2002-11-18 Akim Demaille <akim@epita.fr>
6158 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
6160 From Tim Van Holder.
6162 2002-11-17 Paul Eggert <eggert@twinsun.com>
6164 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
6165 to "SyntaxError" for consistency with my 2002-11-15 change.
6167 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
6168 not define to {}, since this breaks the common use of `YYDPRINTF
6169 ((...));' if a single statement is desired (e.g. before `else').
6170 Work around GCC warnings by surrounding corresponding calls with
6172 (yyhasResolvedValue): Remove unused function.
6173 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
6175 (yyreportSyntaxError): Renamed from yyreportParseError.
6176 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
6178 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
6179 extern when possible. Remove unused initializations.
6181 2002-11-16 Akim Demaille <akim@epita.fr>
6183 Augment the similarity between GLR and LALR traces.
6185 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
6186 (YY_REDUCE_PRINT): New.
6187 (yyparse): Use them.
6188 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
6190 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
6191 state reached after the reduction/recovery, since...
6192 (yyparse, yyprocessOneStack): Report the state we are entering in.
6194 2002-11-16 Akim Demaille <akim@epita.fr>
6196 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
6197 Add support for --trace=skeleton.
6198 * src/scan-skel.l: %option debug.
6199 Scan strings of non-@ or \n instead of character by character.
6200 (scan_skel): Handle trace_skeleton.
6202 (@output_parser_name@, @output_header_name@): ``Restore'' their
6203 support (used to be M4 macros).
6204 * data/yacc.c: Quote larger chunks, a la glr.c.
6205 * data/lalr1.cc: Likewise.
6206 The header guards are no longer available, so use some other
6207 string than `YYLSP_NEEDED'.
6209 2002-11-16 Akim Demaille <akim@epita.fr>
6211 Make the ``Printers and Destructors'' test more verbose, taking
6212 `yacc.c''s behavior as (possibly wrong) reference.
6214 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
6215 instead of fprint on stdout.
6216 Set and report the last_line of the symbols.
6217 Consistently display values and locations.
6219 2002-11-16 Paul Eggert <eggert@twinsun.com>
6221 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
6223 2002-11-15 Paul Eggert <eggert@twinsun.com>
6225 * tests/actions.at (Actions after errors): New test case.
6227 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
6228 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
6229 tests/action.at, tests/calc.at, tests/conflicts.at,
6230 tests/cxx-type.at, tests/regression.at:
6231 "parse error" -> "syntax error" for POSIX compatibility.
6232 "parsing stack overflow..." -> "parser stack overflow" so
6233 that code matches Bison documentation.
6235 2002-11-15 Akim Demaille <akim@epita.fr>
6237 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
6238 take two BRACED_CODE, not two string_content.
6239 Free the scanner's obstack when we are done.
6240 (code_content): New.
6241 * tests/calc.at: Adjust.
6242 * doc/bison.texinfo: Adjust.
6243 Also, make sure to include the `,' for these declarations.
6245 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
6247 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
6248 definition; avoids potential autoreconf problems.
6250 2002-11-15 Akim Demaille <akim@epita.fr>
6252 Always check the value returned by yyparse.
6254 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
6255 returned by yyparse.
6256 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
6258 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
6259 returned by yyparse.
6261 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6263 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
6266 2002-11-14 Paul Eggert <eggert@twinsun.com>
6268 * src/output.c (output_skeleton): Call xfopen instead of
6269 duplicating xfopen's body.
6271 Fix bugs reported by Nelson H. F. Beebe in
6272 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
6274 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
6275 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
6276 Group compiler. Instead, use "$CC -E bar.c". Include the .h
6277 file twice in the grammar, as an extra check.
6279 * tests/input.at (Torturing the Scanner): Surround the
6280 backslash-newline tests with "#if 0", to make it less likely that
6281 we'll run into compiler bugs. Bring back solitary \ inside
6282 comment, but add a closing comment to work around HP C bug. Don't
6283 test backslash-newline in C character constant.
6285 2002-11-14 Akim Demaille <akim@epita.fr>
6287 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
6288 status of the compiler.
6289 Calling `exit 1' is no longer needed.
6290 Reported by Nelson H. F. Beebe.
6292 2002-11-14 Akim Demaille <akim@epita.fr>
6294 * tests/atlocal.in (CPPFLAGS): We have config.h.
6295 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):

6298 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
6299 * tests/regression.at, tests/torture.at: Use them for all the
6300 grammars that are to be compiled.

6302 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
6303 * doc/bison.texinfo (GLR Parsers): Document `inline'.
6305 2002-11-14 Akim Demaille <akim@epita.fr>
6307 * doc/bison.texinfo: Various formatting changes (alignments in
6308 samples, additional @group/@end group, GCS in samples.
6309 Use @deffn instead of simple @table to define the directives,
6310 macros, variables etc.
6312 2002-11-13 Paul Eggert <eggert@twinsun.com>
6314 Fix some bugs reported by Albert Chin-A-Young in
6315 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
6317 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
6318 -o c"; the HP C compiler chatters during compilation.
6319 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
6320 * tests/headers.at (export YYLTYPE): Likewise.
6322 * tests/input.at (Torturing the Scanner): Remove lines containing
6323 solitary backslashes, as they tickle a bug in the HP C compiler.
6325 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
6326 comments, since they're not portable. Use GNU coding style.
6328 2002-11-13 Akim Demaille <akim@epita.fr>
6330 * data/yacc.c: Leave bigger chunks of quoted text.
6331 (YYDSYMPRINTF): New.
6332 Use it to report symbol activities.
6333 * data/glr.c (YYDSYMPRINTF): New.
6336 2002-11-12 Paul Eggert <eggert@twinsun.com>
6340 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
6341 (yyglrReduce): Return yyok, not 0.
6342 This should avoid the enumerated-type warnings reported
6343 by Nelson H. F. Beebe in
6344 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
6346 * lib/bbitset.h (BITSET_INLINE): Remove.
6347 * lib/bitset.h [! BITSET_INLINE]: Remove.
6348 (bitset_set, bitset_reset, bitset_test): Rename local vars
6349 to avoid shadowing warnings by GCC.
6351 * data/glr.c (inline): Remove #define. It's the user's
6352 responsibility to #define it away, just like 'const'.
6353 This fixes one of the bugs reported by Nelson H. F. Beebe in
6354 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
6356 * Makefile.maint (po-check): Scan .l and .y files instead of the
6357 .c and the .h files that they generate. This fixes the bug
6358 reported by Tim Van Holder in:
6359 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
6360 Look for N_ as well as for _. Try to avoid matching #define for
6362 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
6363 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
6364 * src/scan-gram.l: Revamp regular expressions so that " and '
6365 do not confuse xgettext.
6367 * src/struniq.h (struniq_new): Do not declare the return type
6368 to be 'const'; this violates the C standard.
6369 * src/struniq.c (struniq_new): Likewise.
6371 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
6373 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
6374 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq

6396 2002-11-12 Akim Demaille <akim@epita.fr>
6398 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
6399 Use it to test the GLR parser.
6401 2002-11-12 Akim Demaille <akim@epita.fr>
6403 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
6405 * data/glr.c (yystos): New.
6406 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
6408 (yyval): Don't define it, it is handled via M4.
6409 (yyrecoverParseError): Free verbosely the discarded symbols.
6410 * data/yacc.c (yysymprint): Remove, rather...
6411 (b4_yysymprint_generate): invoke.
6412 * data/c.m4 (b4_yysymprint_generate): New.
6413 Accept pointers as arguments, as opposed to the version from
6415 (b4_yydestruct_generate): Likewise.
6416 * tests/cations.at (Printers and Destructors): Use Bison directives
6417 instead of CPP macros.
6418 Don't rely on internal details.
6420 2002-11-12 Akim Demaille <akim@epita.fr>
6422 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
6423 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
6424 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
6425 it against YYEMPTY and so forth), work on yytoken (i.e., set
6426 it to YYEMPTY etc.).
6427 (yydestruct): Replace with a b4_yydestruct_generate invocation.
6428 (b4_symbol_actions): Remove.
6429 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
6430 for 0, end-of-input.

6434 * doc/bison.texinfo (Destructor Decl): New.
6436 2002-11-12 Akim Demaille <akim@epita.fr>
6438 * src/tables.c (tables_generate): Use free for pointers that
6439 cannot be NULL, not XFREE.
6440 (pack_vector): Use assert, not fatal, for bound violations.
6441 * src/state.c (state_new): Likewise.
6442 * src/reader.c (reader): Likewise.
6443 * src/lalr.c (set_goto_map): Likewise.
6444 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
6447 2002-11-12 Akim Demaille <akim@epita.fr>

6451 * src/scan-gram.l (last_string): Is global to the file, not to
6453 * src/parse-gram.y (input): Don't append the epilogue here,
6454 (epilogue.opt): do it here, and free the scanner's obstack.
6455 * src/reader.c (epilogue_set): Rename as...
6456 (epilogue_augment): this.
6457 * data/c.m4 (b4_epilogue): Defaults to empty.

6515 2002-11-11 Paul Eggert <eggert@twinsun.com>
6517 Revamp to fix many (but not all) of the C- and M4-related quoting
6518 problems. Among other things, this fixes the Bison bug reported
6519 by Jan Hubicka when processing the Bash grammar; see:
6520 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6522 Use new @ escapes consistently. Represent brackets with @{ and @}
6523 rather than @<:@ and @:>@, since this works a bit better with dumb
6524 editors like vi. Represent @ with @@, since @ is now consistently
6525 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6526 __ofile__, to avoid unexpected expansions. Similarly, use @output
6527 rather than #output.
6529 * data/c.m4 (b4_copyright): Omit file name from comment, since
6530 the file name could contain "*/".
6531 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6532 be quoted. All uses changed.
6534 * data/glr.c: Use new @ escapes consistently.
6535 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6536 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6537 Remove, since they couldn't handle arbitrary characters in file
6539 * data/lalr1.cc: Likewise.
6540 * data/yacc.c: Likewise.
6542 * src/files.c (output_infix): Remove; all uses removed.
6543 * src/files.h: Likewise.
6545 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6546 mishandled funny characters in file names, and anyway it isn't
6548 * data/yacc.c: Likewise.
6549 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6551 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6552 * data/yacc.c: Likewise.
6554 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6556 (muscle_init): Quote filename as a C string.
6557 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6558 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6559 * src/output.c (escaped_file_name_output): New function.
6560 (prepare_symbols): Quote tokens for M4.
6561 (prepare): Don't insert output_infix, output_prefix,
6562 output_parser_name, output_header_name; this is now down by scan-skel.
6563 Insert skeleton as a C string.
6565 * src/output.c (user_actions_output, symbol_destructors_output,
6566 symbol_printers_output): Quote filenames for C and M4.
6567 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6569 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash

6571 (<SC_STRING>): Likewise, for \\ and \".
6572 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6573 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6574 Use new escapes @{ and @} for [ and ].
6576 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6577 them with auto vars.
6578 Switch to new escape scheme, where @ is the escape character uniformly.
6579 Abort if a stray escape character is found. Avoid unbounded input
6580 buffer when parsing non-escaped text.
6582 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6583 __oline__, #output, $@, and @{ do not have unintended meanings.
6585 2002-11-09 Paul Eggert <eggert@twinsun.com>
6587 Fix the test failure due to GCC warnings described in
6588 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6589 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6590 evaluate to 0 if it's impossible for NINF to be in the respective
6592 (yygetLRActions, yyrecoverParseError): Use them.
6594 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6595 counted in the token inserted at end of file. Now takes
6596 location_t *, not location_t, so that the location can be
6597 adjusted. All uses changed.
6599 * tests/regression.at (Invalid inputs): Adjust wording in
6600 diagnostic to match the new behavior.
6602 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6603 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6604 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6605 abort ();'. This reduces the runtime of the "Many lookaheads"

6609 2002-11-07 Paul Eggert <eggert@twinsun.com>
6611 * src/parse-gram.y (CHARACTER): Remove unused token.
6614 * src/scan-gram.l: Remove stack option. We no longer use the
6615 stack, since the stack was never deeper than 1; instead, use the
6616 new auto var c_context to record the stacked value.
6618 Remove nounput option. At an unexpected end of file, we now unput
6619 the minimal input necessary to end cleanly; this simplifies the
6622 Avoid unbounded token sizes where this is easy.
6624 (unexpected_end_of_file): New function.
6625 Use it to systematize the error message on unexpected EOF.
6626 (last-string): Now auto, not static.

6631 not the (never otherwised-used) CHARACTER.
6633 2002-11-07 Akim Demaille <akim@epita.fr>

6653 * src/output.c (symbol_printers_output)
6654 (symbol_destructors_output): Quote the file name.

6683 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6685 * src/tables.c (matching_state): Don't allow states to match if
6686 either has GLR conflict entries.
6688 2002-11-05 Paul Eggert <eggert@twinsun.com>
6690 * src/scan-gram.l: Use more accurate diagnostics, e.g.
6691 "integer out of range" rather than "invalid value".
6692 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
6695 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
6696 Also, remove one static variable in the scanner.
6698 * src/scan-gram.l (braces_level): Now auto, not static.
6699 Initialize to zero if the compiler is being picky.
6700 (INITIAL): Clear braces_level instead of incrementing it.
6701 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
6702 as POSIX 1003.1-2001 requires.
6703 * src/system.h (IF_LINT): New macro, taken from coreutils.
6704 * configure.ac: Define "lint" if --enable-gcc-warnings.
6706 2002-11-05 Akim Demaille <akim@epita.fr>
6708 * src/scan-gram.l: When it starts with `%', complain about the
6709 whole directive, not just that `invalid character: %'.

6713 * Makefile.maint: Update from Autoconf.
6714 (update, cvs-update, po-update, do-po-update): New.

6722 returns true when location & yacc & pure & parse-param.
6723 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
6725 2002-11-04 Akim Demaille <akim@epita.fr>
6727 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
6729 * src/scan-gram.l: Use [\'] instead of ['] to pacify
6732 Use quote, not quote_n since LOCATION_PRINT no longer uses the
6735 2002-11-03 Paul Eggert <eggert@twinsun.com>
6737 * src/reader.c (get_merge_function, grammar_current_rule_check):
6738 Use consistent diagnostics for reporting type name clashes.
6739 Quote the types with <>, for consistency with Yacc.
6740 * tests/input.at (Type Clashes): Adjust to diagnostic changes.

6753 Use b4_identification.
6754 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
6755 b4_user_formals and b4_user_args.
6756 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
6757 (yyreportAmbiguity): When using a pure parser, also need
6758 the location, and the parse-params.
6760 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
6761 When using a pure parser, also need the parse-params.
6763 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
6764 (%pure-parser + %parse-param) LALR and GLR parsers.
6765 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
6766 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
6767 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
6768 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

6779 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
6780 AT_CHECK_CALC_GLR invocations to use % directives, instead of
6781 command line options.
6782 * tests/cxx-type.at: Formatting changes.
6784 2002-11-03 Paul Eggert <eggert@twinsun.com>
6786 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
6787 to count columns correctly, and to check for invalid inputs.
6789 Use mbsnwidth to count columns correctly. Account for tabs, too.
6791 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
6792 (extend_location): New function.
6795 Handle CRLF in C code rather than in Lex code.

6799 Scan UCNs, even though we don't fully handle them yet.
6800 (convert_ucn_to_byte): New function.
6802 Handle backslash-newline correctly in C code.
6803 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
6804 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;

6807 Use {splice} wherever C allows backslash-newline.
6808 YY_STEP after space, newline, vertical-tab.
6809 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
6811 (letter, id): Don't assume ASCII; e.g., spell out a-z.
6813 ({int}, handle_action_dollar, handle_action_at): Check for integer
6816 (YY_STEP): Omit trailing semicolon, so that it's more like C.
6818 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
6819 as well as \000. Check for UCHAR_MAX, not 255.
6820 Allow \x with an arbitrary positive number of digits, as in C.
6821 Check for overflow here.
6822 Allow \? and UCNs, for compatibility with C.
6824 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
6825 with quote slot used by complain_at.
6827 * tests/input.at: Add tests for backslash-newline, m4 quotes

6830 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
6831 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

6844 2002-11-02 Paul Eggert <eggert@twinsun.com>
6846 * src/reader.c: Don't include quote.h; not needed.
6847 (get_merge_function): Reword warning to be consistent with
6848 type clash diagnostic in grammar_current_rule_check.
6850 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
6851 bug in trigraph handling.
6853 * src/output.c (prepare_symbols): When printing token names,
6854 escape "[" as "@<:@" and likewise for "]".
6856 * src/system.h (errno): Remove declaration, as we are now
6857 assuming C89 or better, and C89 guarantees errno.
6859 2002-10-30 Paul Eggert <eggert@twinsun.com>
6861 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
6862 Check for close failures.
6863 * src/files.h (xfclose): Return void, not int, since it always
6865 * src/files.c (xfclose): Likewise. Report I/O error if ferror
6867 * src/output.c (output_skeleton): Use xfclose rather than fclose
6868 and ferror. xfclose now checks ferror.
6870 * data/glr.c (YYLEFTMOST_STATE): Remove.
6871 (yyreportTree): Use a stack-based leftmost state. This avoids
6872 our continuing battles with bogus warnings about initializers.
6874 2002-10-30 Akim Demaille <akim@epita.fr>
6876 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
6879 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6881 * tests/glr-regr1.at: New test for reported regressions.
6882 * tests/testsuite.at: Add glr-regr1.at test.
6883 * tests/Makefile.am: Add glr-regr1.at test.

6889 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6890 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6891 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6892 Don't assume strdup exists; POSIX says its an XSI extension.
6893 Check for buffer overflow on input.
6895 2002-10-24 Akim Demaille <akim@epita.fr>
6897 * src/output.c (output_skeleton): Don't disable M4sugar comments
6898 too soon: it results in comments being expanded.
6899 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6902 2002-10-24 Akim Demaille <akim@epita.fr>
6904 * data/yacc.c (m4_int_type): New.
6905 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6906 char' as only yacc.c wants K&R portability.

6909 Reported by Quoc Peyrot.
6911 2002-10-23 Paul Eggert <eggert@twinsun.com>
6913 * src/main.c (main): With --trace=time, report times even if a
6914 non-fatal error occurs. Formerly, the times were reported in some
6915 such cases but not in others.
6916 * src/reader.c (reader): Just return if a complaint has been issued,
6917 instead of exiting, so that 'main' can report times.
6919 2002-10-22 Akim Demaille <akim@epita.fr>
6921 * src/system.h: Include sys/types.
6922 Reported by Bert Deknuydt.

6931 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6932 decl; not needed any more.
6933 * src/main.c (main): Use return to exit, undoing yesterday's change.
6934 The last OS that we could find where this wouldn't work is
6935 SunOS 3.5, and that's too old to worry about now.
6937 * data/glr.c (struct yyltype): Define members even when not
6938 doing locations. This is more consistent with yacc.c, and it
6939 works around the following bug reports:
6940 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6941 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6943 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6944 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6945 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6947 2002-10-22 Akim Demaille <akim@epita.fr>
6951 2002-10-21 Paul Eggert <eggert@twinsun.com>
6953 Be consistent about 'bool'; the old code used an enum in one
6954 module and an int in another, and this violates the C standard.
6955 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6956 * configure.ac (AC_HEADER_STDBOOL): Add.
6957 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
6958 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
6959 * src/symtab.c (hash_compare_symbol_t): Likewise.
6960 * src/system.h (bool, false, true): Use a definition consistent
6961 with ../lib/hash.c. All uses changed.
6963 * src/complain.c (warning_issued): Renamed from warn_message_count,
6964 so that we needn't worry about integer overflow (!).
6965 Now of type bool. All uses changed.
6966 (complaint_issued): Renamed from complain_message_count; likewise.
6968 * src/main.c (main): Use exit to exit with failure.
6970 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6971 rather than 1 and 0.
6972 * src/main.c (main): Likewise.
6973 * src/getargs.c (getargs): Likewise.
6974 * src/reader.c (reader): Likewise.
6976 * src/getarg.c (getargs): Remove duplicate code for
6977 "Try `bison --help'".
6979 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6980 What was that "2" for?
6982 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6983 * src/getargs.c (usage): Likewise.
6985 * src/getargs.c (getargs): When there are too few operands, report
6986 the last one. When there are too many, report the first extra
6987 one. This is how diffutils does it.
6989 2002-10-20 Paul Eggert <eggert@twinsun.com>
6991 Remove K&R vestiges.
6992 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
6993 * src/complain.c (VA_START): Remove. Assume prototypes.
6994 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
6995 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
6996 fatal): Assume prototypes.
6997 * src/complain.h: Assume prototypes.
6998 * src/system.h (PARAMS): Remove.
6999 Include <limits.h> unconditionally, since it's guaranteeed even
7000 for a freestanding C89 compiler.
7001 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
7002 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
7004 2002-10-20 Akim Demaille <akim@epita.fr>
7006 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
7007 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
7008 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
7009 (yyresolveStates, yyresolveAction, yyresolveStack)
7010 (yyprocessOneStack): Use them.
7011 (yy_reduce_print): New.
7012 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
7014 2002-10-20 Akim Demaille <akim@epita.fr>
7016 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
7017 arguments and output `void'.
7018 (b4_c_function): Rename as...
7019 (b4_c_function_def): this.
7020 (b4_c_function_decl, b4_c_ansi_function_def)
7021 (b4_c_ansi_function_decl): New.
7022 Change the interpretation of the arguments: before `int, foo', now
7024 * data/yacc.c (yyparse): Prototype and define thanks to these.
7025 Adjust b4_c_function_def uses.
7026 * data/glr.c (yyparse): Likewise, but ANSI only.
7028 2002-10-20 Akim Demaille <akim@epita.fr>
7030 * src/output.c (prepare): Move the definition of `tokens_number',
7031 `nterms_number', `undef_token_number', `user_token_number_max'
7033 (prepare_tokens): Here.
7034 (prepare_tokens): Rename as...
7035 (prepare_symbols): this.
7036 (prepare): Move the definition of `rules_number' to...
7037 (prepare_rules): here.
7038 (prepare): Move the definition of `last', `final_state_number',
7039 `states_number' to...
7040 (prepare_states): here.
7041 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
7043 2002-10-20 Akim Demaille <akim@epita.fr>
7045 * src/tables.h, src/tables.c, src/output.c: Comment changes.

7063 2002-10-19 Paul Eggert <eggert@twinsun.com>
7065 Do not create a temporary file, as that involves security and
7066 cleanup headaches. Instead, use a pair of pipes.
7067 Derived from a suggestion by Florian Krohm.
7068 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
7069 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
7070 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
7071 (BISON_PREREQ_SUBPIPE): Add.
7072 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

7076 * src/output.c: Include "subpipe.h".
7077 (m4_invoke): Remove decl.
7078 (scan_skel): New decl.
7079 (output_skeleton): Use pipe rather than temporary file for m4 input.
7080 Check that m4sugar.m4 is readable, to avoid deadlock.
7081 Check for pipe I/O error.
7082 * src/scan-skel.l (readpipe): Remove decl.
7083 (scan_skel): New function, to be used in place of m4_invoke.
7084 Read from stream rather than file.
7086 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
7087 float, as this generates a warning on Solaris 8 + GCC 3.2 with
7088 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
7089 this generates a more-accurate value anyway.
7091 * lib/timevar.c (timervar_accumulate): Rename locals to
7092 avoid confusion with similarly-named more-global.
7093 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
7095 * src/output.c (prepare): Use xstrdup to convert char const *
7096 to char *, to avoid GCC warning.
7098 2002-10-19 Akim Demaille <akim@epita.fr>
7100 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
7101 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
7102 Use them to have `calc.y' ready for %pure-parser.
7103 * data/yacc.c (YYLEX): Pass a yylex return type to
7106 2002-10-19 Akim Demaille <akim@epita.fr>
7108 Prototype support of %lex-param and %parse-param.
7110 * src/parse-gram.y: Add the definition of the %lex-param and
7111 %parse-param tokens, plus their rules.
7112 Drop the `_' version of %glr-parser.
7114 * src/scan-gram.l (INITIAL): Scan them.
7115 * src/muscle_tab.c: Comment changes.
7116 (muscle_insert, muscle_find): Rename `pair' as `probe'.
7117 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
7118 (muscle_entry_s): The `value' member is no longer const.
7119 Adjust all dependencies.
7120 * src/muscle_tab.c (muscle_init): Adjust: use
7121 MUSCLE_INSERT_STRING.
7122 Initialize the obstack earlier.
7123 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
7124 (muscle_pair_list_grow): New.
7125 * data/c.m4 (b4_c_function_call, b4_c_args): New.
7126 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
7127 * tests/calc.at: Use %locations, not --locations.
7128 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
7130 2002-10-19 Akim Demaille <akim@epita.fr>
7132 * src/getargs.c (usage): Take status as argument and exit
7134 Report the traditional `Try ... --help' message when status != 0.
7135 (usage, version): Don't take a FILE * as arg, it is pointless.
7136 (getargs): When there is an incorrect number of arguments, make it
7137 an error, and report it GNUlically thanks to `usage ()'.
7139 2002-10-18 Paul Eggert <eggert@twinsun.com>
7141 * data/glr.c (yyreportParseError): Don't assume that sprintf
7142 yields the length of the printed string, as this is not true
7143 on SunOS 4.1.4. Reported by Peter Klein.
7145 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
7146 * tests/conflicts.at (%nonassoc and eof): Likewise.
7147 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
7149 2002-10-17 Akim Demaille <akim@epita.fr>
7151 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
7152 * src/getargs.c (trace_types, trace_args): Adjust.
7153 * src/reader.c (grammar_current_rule_prec_set)
7154 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
7155 Standardize error messages.
7157 (reader): Use trace_flag to enable scanner/parser debugging,
7158 instead of an adhoc scheme.
7159 * src/scan-gram.l: Remove trailing debugging code.
7161 2002-10-16 Paul Eggert <eggert@twinsun.com>
7163 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
7166 * NEWS: Officially drop support for building Bison with K&R C,
7167 since it didn't work anyway and it's not worth worrying about.
7168 * Makefile.maint (wget_files): Remove ansi2knr.c.
7169 (ansi2knr.c-url_prefix): Remove.
7170 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
7171 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
7172 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
7174 2002-10-15 Paul Eggert <eggert@twinsun.com>
7176 Stop using the "enum_" trick for K&R-style function definitions;
7177 it confused me, and I was the author! Instead, assume that people
7178 who want to use K&R C compilers (when using these modules in GCC,
7179 perhaps?) will run ansi2knr.
7181 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
7182 All uses of "enum_" changed to "enum ".
7183 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

7194 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
7195 Use function prototypes; this removes the need for declaring
7196 static functions simply to provide their prototypes.
7197 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

7263 2002-10-14 Akim Demaille <akim@epita.fr>
7265 * src/tables.c (table_ninf_remap): base -> tab.
7266 Reported by Matt Rosing.
7268 2002-10-14 Paul Eggert <eggert@twinsun.com>
7270 * tests/action.at, tests/calc.at, tests/conflicts.at,
7271 tests/cxx-type.at, tests/headers.at, tests/input.at,
7272 tests/regression.at, tests/synclines.at, tests/torture.at:
7273 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
7274 so that the tests still work even if POSIXLY_CORRECT is set.
7275 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
7277 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
7278 for portability to K&R hosts. Fix typo: signed char is guaranteed
7279 only to 127, not to 128.
7280 * data/glr.c (yysigned_char): New type.
7281 * data/yacc.c (yysigned_char): Likewise.
7282 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
7284 2002-10-13 Paul Eggert <eggert@twinsun.com>
7286 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
7287 true due to limited range of data type" warning from GCC.
7289 * data/c.m4 (b4_token_defines): Protect against double-inclusion
7290 by wrapping enum yytokentype's definition inside #ifndef
7291 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
7293 2002-10-13 Akim Demaille <akim@epita.fr>
7295 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
7296 Un yy- yyrhs to avoid the name clash with the global YYRHS.
7298 2002-10-13 Akim Demaille <akim@epita.fr>
7300 * Makefile.maint: Update from Autoconf 2.54.
7301 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
7303 2002-10-13 Akim Demaille <akim@epita.fr>
7305 * src/print.c (print_state): Separate the list of solved conflicts
7306 from the other items.

7311 Let nondeterministic skeletons be usable with deterministic
7314 With the patch, GAWK compiled by GCC without -O2 passes its test
7315 suite using a GLR parser driven by LALR tables. It fails with -O2
7316 because `struct stat' gives two different answers on my machine:
7317 88 (definition of an auto var) and later 96 (memset on this var).
7318 Hence the stack is badly corrumpted. The headers inclusion is to
7319 blame: if I move the awk.h inclusion before GLR's system header
7320 inclusion, the two struct stat have the same size.
7322 * src/tables.c (pack_table): Always create conflict_table.
7323 (token_actions): Always create conflict_list.
7324 * data/glr.c (YYFLAG): Remove, unused.
7326 2002-10-13 Akim Demaille <akim@epita.fr>
7328 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
7330 (VALGRIND, GXX): New.
7331 * tests/atlocal.in (CFLAGS): Use O0FLAGS.

7337 2002-10-13 Akim Demaille <akim@epita.fr>
7339 * data/glr.c: Formatting changes.
7340 Tweak some trace messages to match yacc.c's.
7342 2002-10-13 Akim Demaille <akim@epita.fr>
7344 GLR parsers sometimes raise parse errors instead of performing the
7346 Reported by Charles-Henry de Boysson.
7348 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
7349 check the length of the traces when %glr.
7350 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
7352 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
7354 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
7355 (yyltype): Remove the yy prefix from the member names.
7356 (yytable): Complete its comment.
7357 (yygetLRActions): Map error action number from YYTABLE from
7359 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
7360 (which was a bug: it should have been YYTABEL_NINF, and yet it was
7361 not satisfying as we could compare an YYACTION computed from
7362 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
7363 only value for error actions.
7364 (yyreportParseError): In verbose parse error messages, don't issue
7365 `error' in the list of expected tokens.
7366 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
7367 next action to perform to match glr.c's decoding.
7368 (yytable): Complete its comment.

7372 Fix problem reported by Henrik Grubbstroem in
7373 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
7374 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
7375 because the Bison parser reads the second action before reducing
7377 * src/scan-gram.l (rule_length): New static var.
7378 Use it to keep track of the rule length in the scanner, since
7379 we can't expect the parser to be in lock-step sync with the scanner.
7380 (handle_action_dollar, handle_action_at): Use this var.
7381 * tests/actions.at (Exotic Dollars): Test for the problem.
7383 2002-10-12 Paul Eggert <eggert@twinsun.com>
7385 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
7386 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
7387 Include <sys/time.h> when checking for clock_t and struct tms.
7388 Use same include order as source.
7389 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
7390 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
7392 * lib/timevar.c: Update copyright date and clarify comments.
7393 (get_time) [IN_GCC]: Keep the GCC version for reference.
7395 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
7396 GCC version as of today, then merge Bison's changes.
7397 Change "GCC" to "Bison" in copyright notice. timevar.def's
7398 author is Akim, so change that too.
7400 * src/reader.c (grammar_current_rule_check):
7401 Don't worry about the default action if $$ is untyped.
7402 Prevents bogus warnings reported by Jim Gifford in
7403 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
7405 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
7406 * data/glr.c, data/lalr1.cc, data/yacc.c:
7407 Output token definitions before the first part of user declarations.
7408 Fixes compatibility problem reported by Jim Gifford for kbd in
7409 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
7411 2002-10-11 Paul Eggert <eggert@twinsun.com>
7413 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
7414 (yyparse): here. This undoes some of the 2002-07-25 change.
7415 Compatibility problem reported by Ralf S. Engelschall with
7416 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

7435 * lib/lbitset.c: Likewise.
7437 * lib/abitset.c (abitset_bytes): Return a size that is aligned
7438 properly for vectors of objects. Do not assume that adding a

7440 properly aligned for the whole union.
7441 * lib/bitsetv.c (bitsetv_alloc): Likewise.

7479 for enum_bitset_type.
7480 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
7481 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
7483 Do not use "struct bitset_struct" to mean different things in
7484 different modules. Not only is this confusing, it violates
7485 the C Standard, which requires that structure types in different
7486 modules must be compatible if one is to be passed to the other.
7487 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
7488 All instances of "struct bitset_struct *" replaced with "bitset".

7532 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
7533 the same width as int. This reapplies a hunk of the 2002-08-12 patch
7534 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
7535 which was inadvertently undone by the 2002-09-30 patch.
7536 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
7537 the same width as int.

7892 to minimize the number of warnings from xgettext.
7893 (handle_action_dollar, handle_action_at): Don't use isdigit,

7895 outside the C locale.

7898 this is a GCC extension and is not portable to other compilers.

7901 Do not include <ctype.h>; no longer needed.
7902 Do not include <malloc.h>; no longer needed (and generates

8137 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
8138 for the time being: %locations ought to provide it to yyerror.

8142 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

10117 * data/bison.c++, data/bison.simple: Don't output the current file
10118 name in #line, to avoid useless diffs between two identical

10435 not be defined yet.
10437 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
10439 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
10440 (Copyright notice): Update.
10442 2002-02-11 Akim Demaille <akim@epita.fr>
10444 * tests/regression.at (%nonassoc and eof): Don't include
10445 nonportable headers.
10447 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
10449 * data/bison.c++: Correct error recovery. Make the user able to
10450 initialize the starting location.
10452 2002-02-07 Akim Demaille <akim@epita.fr>
10454 * tests/input.at: New.
10456 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10458 * data/bison.c++: Replace some direct m4 expansions by constants. Be
10459 more consistent when naming methods and variables. Put preprocessor
10460 directives around tables only needed for debugging.
10462 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10464 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
10466 (yy::b4_name::parse): Use print_.
10468 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10470 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
10472 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10474 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
10476 (yy::b4_name::parse): Build verbose error messages, and use error_.
10478 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10480 * data/bison.c++: Fix m4 quoting in comments.
10482 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10484 * data/bison.c++: Adjust the parser code. Fix some muscles that were
10485 not expanded by m4.
10487 2002-02-05 Akim Demaille <akim@epita.fr>
10489 * data/bison.c++: Adjust to the M4 back end.
10490 More is certainly needed.
10492 2002-02-05 Akim Demaille <akim@epita.fr>
10494 Give a try to M4 as a back end.
10496 * lib/readpipe.c: New, from wdiff.
10497 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
10499 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
10500 specific values. Now it is m4 that performs the lookup.
10501 * src/parse-skel.y: Remove.
10502 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
10503 * src/output.c (actions_output, guards_output)
10504 (token_definitions_output): No longer keeps track of the output
10505 line number, hence remove the second argument.
10506 (guards_output): Check against the guard member of a rule, not the
10509 (output_skeleton): Don't look for the skeleton location, let m4 do
10511 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
10513 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
10514 (prepare): Given that for the time being changesyntax is not
10515 usable in M4, rename the muscles using `-' to `_'.
10516 Define `defines_flag', `output_parser_name' and `output_header_name'.
10517 * src/output.h (actions_output, guards_output)
10518 (token_definitions_output): Adjust prototypes.
10519 * src/scan-skel.l: Instead of scanning the skeletons, it now
10520 processes the output of m4: `__oline__' and `#output'.
10521 * data/bison.simple: Adjust to be used by M4(sugar).
10522 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
10524 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
10525 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
10526 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
10527 shamelessly stolen from CVS Autoconf.
10529 2002-02-05 Akim Demaille <akim@epita.fr>
10531 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
10532 * configure.in: Check for the declarations of free and malloc.
10533 * src/muscle_tab.c: Adjust.
10535 2002-02-05 Akim Demaille <akim@epita.fr>
10537 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
10538 which have no values.
10540 2002-02-05 Akim Demaille <akim@epita.fr>
10542 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
10545 2002-01-29 Paul Eggert <eggert@twinsun.com>
10547 * src/bison.simple (YYSIZE_T): Do not define merely because
10548 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
10549 On some platforms, <alloca.h> does not declare YYSTD (size_t).
10551 2002-01-27 Akim Demaille <akim@epita.fr>
10553 Fix `%nonassoc and eof'.
10555 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
10556 which were not properly copied! Replace
10557 memcpy (res->errs, src->errs, src->nerrs);
10559 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
10561 * tests/regression.at (%nonassoc and eof): Adjust to newest
10562 Autotest: `.' is not in the PATH.
10564 2002-01-27 Akim Demaille <akim@epita.fr>
10566 * tests/sets.at (AT_EXTRACT_SETS): New.
10567 (Nullable): Use it.
10570 2002-01-26 Akim Demaille <akim@epita.fr>
10572 * tests/actions.at, tests/calc.at, tests/headers.at,
10573 * tests/torture.at: Adjust to the newest Autotest which no longer
10574 forces `.' in the PATH.
10576 2002-01-25 Akim Demaille <akim@epita.fr>
10578 * tests/regression.at (%nonassoc and eof): New.
10579 Suggested by Robert Anisko.
10581 2002-01-24 Akim Demaille <akim@epita.fr>
10583 Bison dumps core when trying to complain about broken input files.
10584 Reported by Cris van Pelt.
10586 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
10587 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
10589 (Invalid inputs): Strengthen: exercise parse_percent_token.
10591 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
10593 * src/Makefile.am: Add bison.c++.
10594 * src/bison.c++: New skeleton.
10596 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
10600 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
10602 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
10604 2002-01-20 Marc Autret <marc@gnu.org>
10606 * src/files.c (compute_output_file_names): Fix
10608 2002-01-20 Marc Autret <marc@gnu.org>
10610 * tests/output.at: New test.
10611 * src/files.c (compute_base_names): Don't map extensions when
10612 the YACC flag is set, use defaults.
10613 Reported by Evgeny Stambulchik.
10615 2002-01-20 Marc Autret <marc@gnu.org>
10617 * src/system.h: Need to define __attribute__ away for non-GCC
10618 compilers as well (i.e., the vendor C compiler).
10619 Suggested by Albert Chin-A-Young.
10621 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
10623 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
10624 canonical definition.
10625 * src/system.h: Use the canonical definition for PARAMS (avoids
10626 a conflict with the macro from lib/hash.h).
10628 2002-01-11 Akim Demaille <akim@epita.fr>
10630 * configure.in: Use AC_FUNC_STRNLEN.
10631 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
10633 2002-01-09 Akim Demaille <akim@epita.fr>
10635 * src/files.c, src/files.h (output_infix): New.
10636 (tab_extension): Remove.
10637 (compute_base_names): Compute the former, drop the latter.
10638 * src/output.c (prepare): Insert the muscles `output-infix', and
10640 * src/parse-skel.y (string, string.1): New.
10641 (section.header): Use it.
10642 (section.yacc): Remove.
10643 (prefix): Remove too.
10644 * src/scan-skel.l: Adjust.
10645 * src/bison.simple, src/bison.hairy: Adjust.
10647 2002-01-09 Akim Demaille <akim@epita.fr>
10649 * configure.in (WERROR_CFLAGS): Compute it.
10650 * src/Makefile.am (CFLAGS): Pass it.
10651 * tests/atlocal.in (CFLAGS): Idem.
10652 * src/files.c: Fix a few warnings.
10653 (get_extension_index): Remove, unused.
10655 2002-01-08 Akim Demaille <akim@epita.fr>
10657 * src/getargs.c (AS_FILE_NAME): New.
10658 (getargs): Use it to convert DOSish file names.
10659 * src/files.c (base_name): Rename as full_base_name to avoid
10660 clashes with `base_name ()'.
10661 (filename_split): New.
10662 (compute_base_names): N-th rewrite, using filename_split.
10664 2002-01-08 Akim Demaille <akim@epita.fr>
10666 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10667 New, stolen from the Fileutils 4.1.
10668 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10669 * configure.in: Check for the presence of memrchr, and of its
10672 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10674 * lib/hash.h (__P): Added definition for this macro.
10675 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10676 BUILT_SOURCES, to ensure they are generated first.
10677 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10678 %error-verbose to allow bootstrapping with bison 1.30x.
10680 2002-01-06 Akim Demaille <akim@epita.fr>
10682 * src/reader.c (parse_braces): Don't fetch the next char, the
10683 convention is to fetch on entry.
10684 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10685 'switch' without a following semicolon.
10686 * tests/regression.at (braces parsing): New.
10688 2002-01-06 Akim Demaille <akim@epita.fr>
10690 Bison is dead wrong in its RR conflict reports.
10692 * tests/torture.at (GNU Cim Grammar): New.
10693 * src/conflicts.c (count_rr_conflicts): Fix.
10695 2002-01-06 Akim Demaille <akim@epita.fr>
10697 Creating package.m4 from configure.ac causes too many problems.
10699 * tests/Makefile.am (package.m4): Create it by hand,
10700 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10702 2002-01-06 Akim Demaille <akim@epita.fr>
10704 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10707 2002-01-04 Paul Eggert <eggert@twinsun.com>
10709 * doc/bison.texinfo (Debugging):
10710 Remove YYSTDERR; it's no longer defined or used.
10711 Also, s/cstdio.h/cstdio/.
10713 2002-01-03 Akim Demaille <akim@epita.fr>
10715 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10717 2002-01-03 Akim Demaille <akim@epita.fr>
10719 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10720 tracing code to --trace, wait for a better --trace option, with
10723 2002-01-03 Akim Demaille <akim@epita.fr>
10725 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10726 The ISO C++ standard is extremely clear about it: stderr is
10727 considered a macro, not a regular symbol (see table 94 `Header
10728 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10729 Therefore std:: does not apply to it. It still does with fprintf.
10730 Also, s/cstdio.h/cstdio/.
10732 2002-01-03 Akim Demaille <akim@epita.fr>
10734 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10735 for non system headers.
10737 2002-01-02 Akim Demaille <akim@epita.fr>
10739 Equip the skeleton chain with location tracking, runtime trace,
10740 pure parser and scanner.
10742 * src/parse-skel.y: Request a pure parser, locations, and prefix
10744 (%union): Having several members with the same type does not help
10745 type mismatches, simplify.
10746 (YYPRINT, yyprint): New.
10747 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10748 (skel_error): this.
10750 * src/scan-skel.l: Adjust to these changes.
10751 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10752 (LOCATION_PRINT, skel_control_t): New.
10754 2001-12-30 Akim Demaille <akim@epita.fr>
10756 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10757 replace `gb' with BLANKS.
10758 * src/scan-skel.l: Adjust.
10760 2001-12-30 Akim Demaille <akim@epita.fr>
10762 * src/system.h: We don't need nor want bcopy.
10763 Throw away MS-DOS crap: we don't need getpid.
10764 * configure.in: We don't need strndup. It was even causing
10765 problems: because Flex includes the headers *before* us,
10766 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10768 * lib/xstrndup.c: New.
10769 * src/scan-skel.l: Use it.
10770 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10771 * src/parse-skel.y: Use %directives instead of #defines.
10773 2001-12-30 Akim Demaille <akim@epita.fr>
10775 * src/skeleton.h: New.
10776 * src/output.c (output_parser, output_master_parser): Remove, dead
10778 * src/output.h (get_lines_number, actions_output, guards_output)
10779 (token_definitions_output): Prototype them.
10780 * src/parse-skel.y: Add the license notice.
10781 Include output.h and skeleton.h.
10782 (process_skeleton): Returns void, and takes a single parameter.
10783 * src/scan-skel.l: Add the license notice.
10784 Include skeleton.h.
10785 Don't use %option yylineno: it seems that then Flex imagines
10786 REJECT has been used, and therefore it won't reallocate its
10787 buffers (which makes no other sense to me than a bug). It results
10788 in warnings for `unused: yy_flex_realloc'.
10790 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10792 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10793 (MUSCLE_INSERT_PREFIX): ...to there.
10794 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10795 (MUSCLE_INSERT_PREFIX): Move from here...
10797 * src/bison.hairy: Add a section directive. Put braces around muscle
10798 names. This parser skeleton is still broken, but Bison should not
10799 choke on a bad muscle 'syntax'.
10800 * src/bison.simple: Add a section directive. Put braces around muscle
10803 * src/files.h (strsuffix, stringappend): Add declarations.
10804 (tab_extension): Add declaration.
10805 (short_base_name): Add declaration.
10807 * src/files.c (strsuffix, stringappend): No longer static. These
10808 functions are used in the skeleton parser.
10809 (tab_extension): New.
10810 (compute_base_names): Use the computations done in this function
10811 to guess if the generated parsers should have '.tab' in their
10813 (short_base_name): No longer static.
10815 * src/output.c (output_skeleton): New.
10816 (output): Disable call to output_master_parser, and give a try to
10817 a new skeleton handling system.
10818 (guards_output, actions_output): No longer static.
10819 (token_definitions_output, get_lines_number): No longer static.
10821 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
10823 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
10826 * src/parse-skel.y: New file.
10827 * src/scan-skel.l: New file.
10829 2001-12-29 Akim Demaille <akim@epita.fr>
10831 %name-prefix is broken.
10833 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10834 Adjust all dependencies.
10835 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10838 Renaming yylval but not yylloc is not consistent. Now we do.
10840 * src/bison.simple: Prefix yylloc if used.
10841 * doc/bison.texinfo (Decl Summary): Document that.
10843 2001-12-29 Akim Demaille <akim@epita.fr>
10845 * doc/bison.texinfo: Promote `%long-directive' over
10847 Remove all references to fixed-output-files, yacc is enough.
10849 2001-12-29 Akim Demaille <akim@epita.fr>
10851 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10852 user prologue. These are defaults.
10853 * tests/actions.at (Mid-rule actions): Make sure the user can
10854 define YYDEBUG and YYERROR_VERBOSE.
10856 2001-12-29 Akim Demaille <akim@epita.fr>
10858 * src/output.c (header_output): Don't forget to export YYLTYPE and
10860 * tests/headers.at (export YYLTYPE): New, make sure it does.
10861 * tests/regression.at (%union and --defines, Invalid CPP headers):
10863 * tests/headers.at: here.
10865 2001-12-29 Akim Demaille <akim@epita.fr>
10867 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
10869 2001-12-29 Akim Demaille <akim@epita.fr>
10871 * tests/actions.at (Mid-rule actions): Output on a single line
10872 instead of several.
10874 2001-12-29 Akim Demaille <akim@epita.fr>
10876 * doc/bison.texinfo: Formatting changes.
10878 2001-12-29 Akim Demaille <akim@epita.fr>
10880 Don't store the token defs in a muscle, just be ready to output it
10881 on command. Now possible via `symbols'. Fixes a memory leak.
10883 * src/output.c (token_definitions_output): New.
10884 (output_parser, header_output): Use it.
10885 * src/reader.c (symbols_save): Remove.
10887 2001-12-29 Akim Demaille <akim@epita.fr>
10889 * src/bison.simple: Do not provide a default for YYSTYPE and
10890 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10893 2001-12-29 Akim Demaille <akim@epita.fr>
10895 Mid-rule actions are simply... ignored!
10897 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10898 the empty-rule associated to the dummy symbol, not to the host
10900 * tests/actions.at (Mid-rule actions): New.
10902 2001-12-29 Akim Demaille <akim@epita.fr>
10906 * src/reader.c (reader): Free grammar.
10908 2001-12-29 Akim Demaille <akim@epita.fr>
10912 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10913 since it allocates it for each state, although only one is needed.
10914 (allocate_storage): Do it here.
10916 2001-12-29 Akim Demaille <akim@epita.fr>
10918 * src/options.h, src/options.c (create_long_option_table): Rename
10920 (long_option_table_new): this, with a clearer prototype.
10921 (percent_table): Remove, unused,
10922 * src/getargs.c (getargs): Adjust.
10924 2001-12-29 Akim Demaille <akim@epita.fr>
10926 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
10927 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
10930 2001-12-29 Akim Demaille <akim@epita.fr>
10932 * src/lalr.c (build_relations): Rename `states' as `states1'.
10933 Sorry, I don't understand exactly what it is, no better name...
10935 2001-12-29 Akim Demaille <akim@epita.fr>
10937 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10938 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
10939 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
10942 2001-12-29 Akim Demaille <akim@epita.fr>
10944 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
10947 2001-12-29 Akim Demaille <akim@epita.fr>
10949 * src/reader.c, src/reader.h (user_toknums): Remove.
10950 Adjust all users to use symbols[i]->user_token_number.
10952 2001-12-29 Akim Demaille <akim@epita.fr>
10954 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
10955 Adjust all users to use symbols[i]->prec or ->assoc.
10957 2001-12-29 Akim Demaille <akim@epita.fr>
10959 * src/reader.c, src/reader.h (tags): Remove.
10960 Adjust all users to use symbols[i]->tag.
10962 2001-12-29 Akim Demaille <akim@epita.fr>
10964 * src/gram.h, src/gram.c (symbols): New, similar to state_table
10966 * src/reader.c (packsymbols): Fill this table.
10968 * src/conflicts.c (resolve_sr_conflict): Adjust.
10969 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10971 Use symbols[i]->tag instead of tags[i].
10973 2001-12-29 Akim Demaille <akim@epita.fr>
10975 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10976 In addition, put a comment in there, to replace...
10977 * tests/regression.at (%union and C comments): Remove.
10979 2001-12-29 Akim Demaille <akim@epita.fr>
10981 * tests/regression.at (Web2c Actions): Blindly move the actual
10982 output as expected output. The contents *seem* right to me, but I
10983 can't pretend reading perfectly parser tables... Nonetheless, all
10984 the other tests pass correctly, the table look OK, even though the
10985 presence of `$axiom' is to be noted: AFAICS it is useless (but
10988 2001-12-29 Akim Demaille <akim@epita.fr>
10990 * src/reader.c (readgram): Don't add the rule 0 if there were no
10991 rules read. In other words, add it _after_ having performed
10992 grammar sanity checks.
10993 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
10995 2001-12-29 Akim Demaille <akim@epita.fr>
10997 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
10998 visible, and some states have now a different number.
11000 2001-12-29 Akim Demaille <akim@epita.fr>
11002 * src/reader.c (readgram): Bind the initial rule's lineno to that
11004 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
11005 (Solved SR Conflicts): Adjust rule 0's line number.
11007 2001-12-29 Akim Demaille <akim@epita.fr>
11009 Fix the `GAWK Grammar' failure.
11011 * src/LR0.c (final_state): Initialize to -1 so that we do compute
11012 the reductions of the first state which was mistakenly confused
11013 with the final state because precisely final_state was initialized
11015 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
11016 now noticed by Bison.
11017 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
11018 have a reduction on $default.
11020 2001-12-29 Akim Demaille <akim@epita.fr>
11022 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
11024 * src/closure.c (print_closure): Likewise.
11025 * src/derives.c (print_derives): Likewise.
11026 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
11029 2001-12-29 Akim Demaille <akim@epita.fr>
11031 * src/lalr.c (lookaheads_print): New.
11032 (lalr): Call it when --trace-flag.
11033 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
11036 2001-12-29 Akim Demaille <akim@epita.fr>
11038 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
11039 when walking through ritem, even via rule->rhs.
11040 * src/reduce.c (dump_grammar, useful_production, reduce_output)
11041 (useful_production, useless_nonterminals): Likewise.
11042 (reduce_grammar_tables): Likewise, plus update nritems.
11043 * src/nullable.c (set_nullable): Likewise.
11044 * src/lalr.c (build_relations): Likewise.
11045 * tests/sets.at (Nullable): Adjust.
11046 Fortunately, now, the $axiom is no longer nullable.
11048 2001-12-29 Akim Demaille <akim@epita.fr>
11050 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

11053 * src/reduce.c (nonterminals_reduce): Likewise.
11054 * src/print_graph.c (print_graph): Likewise.
11055 * src/output.c (output_rule_data): Likewise.
11056 * src/nullable.c (set_nullable): Likewise.
11058 2001-12-29 Akim Demaille <akim@epita.fr>
11060 * src/output.c: Comment changes.
11062 2001-12-27 Paul Eggert <eggert@twinsun.com>
11064 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
11065 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
11066 Sparc, as they were causing more porting problems than the
11067 (minor) performance improvement was worth.
11069 Also, catch up with 1.31's YYSTD.
11071 2001-12-27 Akim Demaille <akim@epita.fr>
11073 * src/output.c (output_gram): Rely on nritems, not the
11074 0-sentinel. See below.
11075 Use -1 as separator, not 0.
11076 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
11077 Rely on -1 as separator in yyrhs, instead of 0.
11078 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
11079 twice `Now at end of input', therefore there are two lines less to
11082 2001-12-27 Akim Demaille <akim@epita.fr>
11084 * tests/regression.at (Unresolved SR Conflicts):
11085 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
11088 2001-12-27 Akim Demaille <akim@epita.fr>
11090 * src/LR0.c (new_state): Recognize the final state by the fact it
11091 is reached by eoftoken.
11092 (insert_start_shifting_state, insert_eof_shifting_state)
11093 (insert_accepting_state, augment_automaton): Remove, since now
11094 these states are automatically computed from the initial state.
11095 (generate_states): Adjust.
11096 * src/print.c: When reporting a rule number to the user, substract
11097 1, so that the axiom rule is rule 0, and the first user rule is 1.
11098 * src/reduce.c: Likewise.
11099 * src/print_graph.c (print_core): For the time being, just as for
11100 the report, depend upon --trace-flags to dump the full set of
11102 * src/reader.c (readgram): Once the grammar read, insert the rule
11103 0: `$axiom: START-SYMBOL $'.
11104 * tests/set.at: Adjust: rule 0 is now displayed, and since the
11105 number of the states has changed (the final state is no longer
11106 necessarily the last), catch up.
11108 2001-12-27 Akim Demaille <akim@epita.fr>
11110 Try to make the use of the eoftoken valid. Given that its value
11111 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
11112 is used instead of > 0 where appropriate, (ii), depend upon nritems
11113 instead of the 0-sentinel.
11115 * src/gram.h, src/gram.c (nritems): New.
11116 Expected to be duplication of nitems, but for the time being...
11117 * src/reader.c (packgram): Assert nritems and nitems are equal.
11118 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
11119 * src/closure.c (print_closure, print_fderives): Likewise.
11120 * src/gram.c (ritem_print): Likewise.
11121 * src/print.c (print_core, print_grammar): Likewise.
11122 * src/print_graph.c: Likewise.
11124 2001-12-27 Akim Demaille <akim@epita.fr>
11126 * src/main.c (main): If there are complains after grammar
11127 reductions, then output the report anyway if requested, then die.
11128 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
11129 * src/reader.c (eoftoken): New.
11130 (parse_token_decl): If the token being defined has value `0', it
11132 (packsymbols): No longer hack `tags' to insert `$' by hand.
11133 Be sure to preserve the value of the eoftoken.
11134 (reader): Make sure eoftoken is defined.
11135 Initialize nsyms to 0: now eoftoken is created just like the others.
11136 * src/print.c (print_grammar): Don't special case the eof token.
11137 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
11138 lie anyway, albeit pleasant.
11139 * tests/calc.at: Exercise error messages with eoftoken.
11140 Change the grammar so that empty input is invalid.
11141 Adjust expectations.
11142 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
11144 2001-12-27 Akim Demaille <akim@epita.fr>
11146 * configure.in: Check the protos of strchr ans strspn.
11147 Replace strchr if needed.
11148 * src/system.h: Provide the protos of strchr, strspn and memchr if
11150 * lib/strchr.c: New.
11151 * src/reader.c (symbols_save): Use strchr.
11153 2001-12-27 Akim Demaille <akim@epita.fr>
11155 * src/print.c, src/print_graph.c (escape): New.
11156 Use it to quote the TAGS outputs.
11157 * src/print_graph.c (print_state): Now errors are in red, and
11158 reductions in green.
11159 Prefer high to wide: output the state number on a line of its own.
11161 2001-12-27 Akim Demaille <akim@epita.fr>
11163 * src/state.h, src/state.c (reductions_new): New.
11164 * src/LR0.c (set_state_table): Let all the states have a
11165 `reductions', even if reduced to 0.

11184 2001-12-27 Akim Demaille <akim@epita.fr>
11186 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
11187 * src/print.c: here.
11188 (lookaheadset, shiftset): New, used as additional storage by
11190 (print_results): Adjust.
11191 (print_shifts, print_gotos, print_errs): New, extracted from...
11192 (print_actions): here.
11193 * src/print_graph.c (print_actions): Remove dead code.
11195 2001-12-27 Akim Demaille <akim@epita.fr>
11197 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
11200 2001-12-27 Akim Demaille <akim@epita.fr>
11202 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
11203 (build_relations): Adjust.
11205 2001-12-27 Akim Demaille <akim@epita.fr>
11207 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
11210 2001-12-27 Akim Demaille <akim@epita.fr>
11212 * src/reader.c (packgram): Catch nitems overflows.
11214 2001-12-27 Akim Demaille <akim@epita.fr>
11216 * src/files.c, src/files.h (guard_obstack): Remove.
11217 * src/output.c (output): Adjust.
11218 * src/reader.c (parse_braces): New, factoring...
11219 (copy_action, copy_guard): these two which are renamed as...
11220 (parse_action, parse_guard): these.
11221 As a voluntary consequence, using braces around guards is now
11224 2001-12-27 Akim Demaille <akim@epita.fr>
11226 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
11227 * src/reader.c (symbol_list): `guard' and `guard_line' are new
11229 (symbol_list_new): Adjust.
11230 (copy_action): action_line is the first line, not the last.
11231 (copy_guard): Just as for actions, store the `action' only, not
11232 the switch/case/break flesh.
11233 Don't parse the user action that might follow the guard, let...
11234 (readgram): do it, i.e., now, there can be an action after a
11236 In other words the guard is just explicitly optional.
11237 (packgram): Adjust.
11238 * src/output.c (guards_output): New.
11239 (output_parser): Call it when needed.
11240 (output): Also free the guard and attrs obstacks.
11241 * src/files.c, src/files.h (obstack_save): Remove.
11242 (output_files): Remove.
11243 As a result, if one needs the former `.act' file, using an
11244 appropriate skeleton which requires actions and guards is now
11246 * src/main.c (main): Adjust.
11247 * tests/semantic.at: New.
11248 * tests/regression.at: Use `input.y' as input file name.
11249 Avoid 8+3 problems by requiring input.c when the test needs the
11252 2001-12-27 Akim Demaille <akim@epita.fr>
11254 * src/reader.c (symbol_list_new): Be sure to initialize all the
11257 2001-12-27 Akim Demaille <akim@epita.fr>
11259 All the hacks using a final pseudo state are now useless.
11261 * src/LR0.c (set_state_table): state_table holds exactly nstates.
11262 * src/lalr.c (nLA): New.
11263 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
11264 instead of lookaheadsp from the pseudo state (nstate + 1).
11266 2001-12-27 Akim Demaille <akim@epita.fr>
11268 * src/output.c (action_row, token_actions): Use a state_t instead
11269 of a integer, and nlookaheads instead of the following state's

11276 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
11277 (conflicts_print, print_reductions): Use a state_t instead of an
11278 integer when referring to a state.
11279 As much as possible, depend upon nlookaheads, instead of the
11280 `lookaheadsp' member of the following state (since lookaheads of
11281 successive states are successive, the difference between state n + 1
11282 and n served as the number of lookaheads for state n).
11283 * src/lalr.c (add_lookback_edge): Likewise.
11284 * src/print.c (print_core, print_actions, print_state)
11285 (print_results): Likewise.

11295 Add plenty of `static'.
11297 2001-12-27 Akim Demaille <akim@epita.fr>
11299 * src/output.c (prepare): Drop the muscle `ntbase' which
11300 duplicates ntokens.
11301 * src/bison.simple: Formatting/comment changes.
11302 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
11303 is an undocumented synonym.
11305 2001-12-22 Akim Demaille <akim@epita.fr>
11307 * src/output.c (output_table_data): Change the prototype to use
11308 `int' for array ranges: some invocations do pass an int, not a
11310 Reported by Wayne Green.
11312 2001-12-22 Akim Demaille <akim@epita.fr>
11314 Some actions of web2c.y are improperly triggered.
11315 Reported by Mike Castle.
11317 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
11318 * tests/regression.at (Web2c): Rename as...
11319 (Web2c Report): this.
11320 (Web2c Actions): New.
11322 2001-12-22 Akim Demaille <akim@epita.fr>

11325 Reported by Mike Castle.
11327 * src/conflicts.c (print_reductions): Fix.
11328 * tests/regression.at (Web2c): New.
11330 2001-12-18 Akim Demaille <akim@epita.fr>
11332 Some host fail on `assert (!"foo")', which expands to
11333 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
11334 Reported by Nelson Beebee.
11336 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
11337 `#define it_succeeded 0' and `assert (it_succeeded)'.
11339 2001-12-17 Marc Autret <autret_m@epita.fr>
11341 * src/bison.simple: Don't hard code the skeleton line and filename.
11342 * src/output.c (output_parser): Rename 'line' as 'output_line'.
11343 New line counter 'skeleton_line' (skeleton-line muscle).
11345 2001-12-17 Paul Eggert <eggert@twinsun.com>
11347 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
11348 YYDEBUG must be defined to a nonzero value.
11350 * src/bison.simple (yytname): Do not assume that the user defines
11351 YYDEBUG to a properly parenthesized expression.
11353 2001-12-17 Akim Demaille <akim@epita.fr>
11355 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
11356 nlookaheads is a new member.
11358 * src/lalr.h (nlookaheads): Remove this orphan declaration.
11359 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
11362 2001-12-17 Akim Demaille <akim@epita.fr>
11364 * src/files.h, src/files.c (open_files, close_files): Remove.
11365 * src/main.c (main): Don't open/close files, nor invoke lex_free,
11367 * src/reader.c (reader): Do it.
11369 2001-12-17 Akim Demaille <akim@epita.fr>
11371 * src/conflicts.c (print_reductions): Formatting changes.
11373 2001-12-17 Akim Demaille <akim@epita.fr>
11375 * src/conflicts.c (flush_shift): Also adjust lookaheadset.

11379 2001-12-17 Akim Demaille <akim@epita.fr>
11381 * src/output.c (output_obstack): Be static and rename as...
11382 (format_obstack): this, to avoid any confusion with files.c's
11384 * src/reader.h (muscle_obstack): Move to...
11385 * src/output.h: here, since it's defined in output.c.
11387 2001-12-17 Akim Demaille <akim@epita.fr>
11389 * src/output.c (action_row, save_column, default_goto)
11390 (sort_actions, matching_state, pack_vector): Better variable
11393 2001-12-17 Akim Demaille <akim@epita.fr>
11395 * src/output.c: Various formatting changes.
11397 2001-12-17 Akim Demaille <akim@epita.fr>
11399 * src/files.c (output_files): Free the output_obstack.
11400 * src/main.c (main): Call print and print_graph conditionally.
11401 * src/print.c (print): Work unconditionally.
11402 * src/print_graph.c (print_graph): Work unconditionally.
11403 * src/conflicts.c (log_resolution): Output only if verbose_flag.
11405 2001-12-16 Marc Autret <autret_m@epita.fr>
11407 * src/output.c (actions_output): Fix. When we use %no-lines,
11408 there is one less line per action.
11410 2001-12-16 Marc Autret <autret_m@epita.fr>
11412 * src/bison.simple: Remove a useless #line directive.
11413 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.

11415 (output_parser): Adjust, now takes care about the lines of a
11417 Fix line numbering.
11418 (actions_output): Computes the number of lines taken by actions.
11419 (output_master_parser): Insert new skeleton which is the name of

11430 2001-12-15 Akim Demaille <akim@epita.fr>
11432 Make `make distcheck' work.
11434 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
11435 system.h which uses libgettext.h.
11437 2001-12-15 Akim Demaille <akim@epita.fr>
11439 * src/nullable.c (set_nullable): Useless rules must be skipped,
11440 otherwise, since we range over their symbols, we might look at a
11441 nonterminal which no longer ``exists'', i.e., it is not counted in
11442 `nvars', hence we overflow our arrays.
11444 2001-12-15 Akim Demaille <akim@epita.fr>
11446 The header can also be produced directly, without any obstack!
11449 * src/files.c, src/files.h (defines_obstack): Remove.
11450 (compute_header_macro): Global.
11451 (defines_obstack_save): Remove.
11452 * src/reader.c (parse_union_decl): No longer output to
11453 defines_obstack: its content can be found in the `stype' muscle
11455 (output_token_translations): Merge into...
11456 (symbols_output): this.
11458 (symbols_save): this.
11460 * src/output.c (header_output): New.
11463 2001-12-15 Akim Demaille <akim@epita.fr>
11465 * src/reader.c (parse_union_decl): Instead of handling two obstack
11466 simultaneously, use one to define the `stype' muscle, and use the
11467 value of the latter to fill defines_obstack.
11468 (copy_comment): Remove.
11469 (copy_comment2): Work for a single obstack.
11471 (copy_comment): this.
11473 2001-12-15 Akim Demaille <akim@epita.fr>
11475 * src/lex.c, src/lex.h (xgetc): No longer static.
11476 * src/reader.c (parse_union_decl): Revamp.
11478 2001-12-15 Akim Demaille <akim@epita.fr>
11480 Still making progress in separating Bison into (i) input, (ii)
11481 process, (iii) output: now we can directly output the parser file
11482 without using table_obstack at all.
11484 * src/files.c, src/files.h (table_obstack): Bye bye.
11485 (parser_file_name): New.
11486 * src/files.c (compute_output_file_names): Compute it.
11487 * src/output.c (actions_output, output_parser)
11488 (output_master_parser): To a file instead of an obstack.
11490 2001-12-15 Akim Demaille <akim@epita.fr>
11492 Attach actions to rules, instead of pre-outputting them to
11495 * src/gram.h (rule_t): action and action_line are new members.
11496 * src/reader.c (symbol_list): Likewise.
11497 (copy_action): Save the actions within the rule.
11498 (packgram): Save them in rule_table.
11499 * src/output.c (actions_output): New.
11500 (output_parser): Use it on `%%actions'.
11501 (output_rule_data): Don't free rule_table.
11503 (prepare): Don't save the `action' muscle.
11504 * src/bison.simple: s/%%action/%%actions/.
11506 2001-12-15 Akim Demaille <akim@epita.fr>
11508 * src/reader.c (copy_action): When --yacc, don't append a `;'
11509 to the user action: let it fail if lacking.
11510 Suggested by Arnold Robbins and Tom Tromey.
11512 2001-12-14 Akim Demaille <akim@epita.fr>
11514 * src/lex.c (literalchar): Simply return the char you decoded, non
11515 longer mess around with obstacks and int pointers.
11516 Adjust all callers.
11518 2001-12-14 Akim Demaille <akim@epita.fr>
11520 * src/lex.c (literalchar): Don't escape the special characters,
11521 just decode them, and keep them as char (before, eol was output as
11522 the 2 char string `\n' etc.).
11523 * src/output.c (output_rule_data): Use quotearg to output the
11526 2001-12-13 Paul Eggert <eggert@twinsun.com>
11528 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11529 Do not infringe on the global user namespace when using C++.
11530 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11531 All uses of `fprintf' and `stderr' changed.
11533 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11535 2001-12-13 Akim Demaille <akim@epita.fr>
11537 The computation of nullable is broken: it doesn't handle empty
11540 * tests/torture.at (GNU AWK Grammar): New.
11541 * tests/sets.at (Nullable): New.
11542 * src/nullable.c (set_nullable): Instead of blindly looping over
11543 `ritems', loop over the rules, and then over their rhs's.
11545 Work around Autotest bugs.
11547 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11548 frame, because Autotest understand lines starting with a `+' as
11549 traces from the shell. Then, they are not processed properly.
11550 Admittedly an Autotest bug, but we don't have time to wait for
11551 Autotest to catch up.
11552 * tests/regression.at (Broken Closure): Adjust to the new table
11555 * tests/sets.at: here.
11557 2001-12-13 Akim Demaille <akim@epita.fr>
11559 * src/closure.c (closure): Use nrules instead of playing tricks
11560 with BITS_PER_WORD.
11562 2001-12-13 Akim Demaille <akim@epita.fr>
11564 * src/print.c (print_actions): Output the handling of `$' as the
11565 traces do: shifting the token EOF. Before EOF was treated as a
11567 * tests/regression.at: Adjust some tests.
11568 * src/print_graph.c (print_core): Complete the set of items via
11569 closure. The next-to-final and final states are still unsatisfying,
11570 but that's to be addressed elsewhere.
11571 No longer output the rule numbers, but do output the state number.
11572 A single loop for the shifts + gotos is enough, but picked a
11573 distinct color for each.
11574 (print_graph): Initialize and finalize closure.
11576 2001-12-13 Akim Demaille <akim@epita.fr>
11578 * src/reader.c (readgram): Remove dead code, an strip useless
11580 (get_type): Remove, unused.
11582 2001-12-12 Akim Demaille <akim@epita.fr>
11584 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11585 on that of lib/error.c.
11587 2001-12-12 Akim Demaille <akim@epita.fr>
11589 Some hosts don't like `/' in includes.
11591 * src/system.h: Include libgettext.h without qualifying the path.
11592 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11595 2001-12-11 Marc Autret <autret_m@epita.fr>
11597 * src/output.c (output_parser): Remove useless muscle.
11599 2001-12-11 Marc Autret <autret_m@epita.fr>
11601 * src/bison.simple: Remove #line just before %%epilogue. It
11602 is now handled in ...
11603 * src/reader.c (read_additionnal_code): Add the output of a
11604 #line for the epilogue.
11606 2001-12-10 Marc Autret <autret_m@epita.fr>
11608 * src/reader.c (copy_definition): Re-use CPP-outed code which
11609 replace precedent remove.
11610 * src/bison.simple: Remove #line before %%prologue because
11611 %%input-line is wrong at this time.
11613 2001-12-10 Marc Autret <autret_m@epita.fr>
11615 * src/reader.c (symbols_output): Clean up.
11616 * src/output.c (output_gram, output): Clean up.
11618 2001-12-10 Akim Demaille <akim@epita.fr>
11620 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11621 * src/LR0.c (set_state_table): here.
11622 * src/lalr.c (lalr): Call it.
11624 2001-12-10 Akim Demaille <akim@epita.fr>
11626 * src/state.h (shifts): Remove the `number' member: shifts are
11627 attached to state, hence no longer need to be labelled with a
11630 2001-12-10 Akim Demaille <akim@epita.fr>
11632 Now that states have a complete set of members, the linked list of
11633 shifts is useless: just fill directly the state's shifts member.
11635 * src/state.h (shifts): Remove the `next' member.
11636 * src/LR0.c (first_state, last_state): Remove.
11637 Adjust the callers.
11638 (augment_automaton): Don't look for the shifts that must be added
11639 a shift on EOF: it is those of the state we looked for! But now,
11640 since shifts are attached, it is no longer needed to looking
11641 merely by its id: its number.
11643 2001-12-10 Akim Demaille <akim@epita.fr>
11645 * src/LR0.c (augment_automaton): Better variable locality.
11646 Remove an impossible branch: if there is a state corresponding to
11647 the start symbol being shifted, then there is shift for the start
11648 symbol from the initial state.
11650 2001-12-10 Akim Demaille <akim@epita.fr>
11652 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11653 only when appropriate: when insert_start_shifting_state' is not
11655 * tests/regression.at (Rule Line Numbers): Adjust.
11657 2001-12-10 Akim Demaille <akim@epita.fr>
11659 * src/LR0.c (augment_automaton): Now that all states have shifts,
11660 merge the two cases addition shifts to the initial state.
11662 2001-12-10 Akim Demaille <akim@epita.fr>
11664 * src/lalr.c (set_state_table): Move to...
11666 * src/lalr.c (lalr): Don't call it...
11667 * src/LR0.c (generate_states): do it.
11668 * src/LR0.h (first_state): Remove, only the table is used.
11670 2001-12-10 Akim Demaille <akim@epita.fr>
11672 * src/LR0.h (first_shift, first_reduction): Remove.
11673 * src/lalr.c: Don't use first_shift: find shifts through the
11676 2001-12-10 Akim Demaille <akim@epita.fr>
11678 * src/LR0.c: Attach shifts to states as soon as they are
11680 * src/lalr.c (set_state_table): Instead of assigning shifts to
11681 state, just assert that the mapping was properly done.
11683 2001-12-10 Akim Demaille <akim@epita.fr>
11685 * src/LR0.c (insert_start_shift): Rename as...
11686 (insert_start_shifting_state): this.
11687 (insert_eof_shifting_state, insert_accepting_state): New.
11688 (augment_automaton): Adjust.
11689 Better locality of the variables.
11690 When looking if the start_symbol is shifted from the initial
11691 state, using `while (... symbol != start_symbol ...)' sounds
11692 better than `while (... symbol < start_symbol ...)': If fail
11693 to see how the order between symbols could be relevant!
11695 2001-12-10 Akim Demaille <akim@epita.fr>
11697 * src/getargs.h: Don't declare `spec_name_prefix' and
11698 `spec_file_prefix', declared by src/files.h.
11699 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11700 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11701 * src/output.c (prepare): Adjust.
11702 * src/reader.c (symbols_output): Likewise.
11703 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11705 2001-12-10 Akim Demaille <akim@epita.fr>
11707 * src/muscle_tab.c (muscle_init): NULL is a better default than
11710 2001-12-10 Akim Demaille <akim@epita.fr>
11712 * src/reader.c (reader): Calling symbols_output once is enough.
11714 2001-12-10 Akim Demaille <akim@epita.fr>
11716 Now that states have a complete set of members, the linked list of
11717 reductions is useless: just fill directly the state's reductions
11720 * src/state.h (struct reductions): Remove member `number' and
11722 * src/LR0.c (first_reduction, last_reduction): Remove.
11723 (save_reductions): Don't link the new reductions, store them in
11725 * src/lalr.c (set_state_table): No need to attach reductions to
11726 states, it's already done.
11727 * src/output.c (output_actions): No longer free the shifts, then
11728 the reductions, then the states: free all the states and their
11731 2001-12-10 Akim Demaille <akim@epita.fr>
11733 * src/options.c (OPTN, DRTV, BOTH): New.
11734 (option_table): Use them.
11736 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11737 the job of system.h.
11738 * src/options.c: Don't include stdio.h and xalloc.h for the same
11741 2001-12-10 Akim Demaille <akim@epita.fr>
11743 * src/output.c (output, prepare): Make sure the values of the
11744 muscles `action' and `prologue' are 0-terminated.
11746 2001-12-10 Akim Demaille <akim@epita.fr>
11748 Clean up GCC warnings.
11750 * src/reader.c (copy_action): `buf' is not used.
11751 (parse_skel_decl): Be static.
11752 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11753 * src/options.h (create_long_option_table): Have a real prototype.
11754 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11755 (hash_delete_at): Return const void *.
11756 Adjust casts to preserve the const.
11758 2001-12-10 Akim Demaille <akim@epita.fr>
11760 * configure.in: Require 2.52g.
11761 M4 is not needed, but AUTOM4TE is.
11762 * m4/m4.m4: Remove.
11763 * tests/Makefile.am: Adjust.
11765 2001-12-10 Akim Demaille <akim@epita.fr>
11767 One structure for states is enough, even though theoretically
11768 there are LR(0) states and LALR(1) states.
11770 * src/lalr.h (state_t): Remove.
11771 (state_table): Be state_t **, not state_t *.
11772 * src/state.h (core, CORE_ALLOC): Rename as...
11773 (state_t, STATE_ALLOC): this.
11774 Add the LALR(1) members: shifts, reductions, errs.
11775 * src/LR0.c (state_table): Rename as...
11776 (state_hash): this, to avoid name clashes with the global
11778 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11779 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11781 2001-12-10 Akim Demaille <akim@epita.fr>
11783 Bison dumps core on bash.y.
11784 Reported by Pascal Bart.
11786 * src/warshall.c (bitmatrix_print): New.
11788 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11789 j must be the outer loop.
11790 * tests/regression.at (Broken Closure): New.
11792 2001-12-05 Akim Demaille <akim@epita.fr>
11794 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and

11801 (resolve_sr_conflict): Adjust.
11802 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
11804 (state_t.reductions, state_t.shifts): this.
11806 2001-12-05 Akim Demaille <akim@epita.fr>
11808 * src/reduce.c (reduce_grammar_tables): No longer disable the
11809 removal of useless rules via CPP but via `if (0)', so that the
11810 compiler still check the code is valid.
11811 For instance, it should have noticed `rline' no longer exists: use
11812 the `line' member of rule_t.
11813 * src/gram.c (dummy, rline): Remove, unused.
11815 2001-12-05 Akim Demaille <akim@epita.fr>
11817 * src/output.c (pack_vector): Use assert, not berror.
11818 * src/main.c (berror): Remove, unused.
11820 2001-12-05 Akim Demaille <akim@epita.fr>
11822 New experimental feature: if --verbose --trace output all the
11823 items of a state, not only its kernel.
11825 * src/print.c (print_core): If `trace_flag', then invoke closure
11826 before outputting the items of the state (print_core is no longer
11827 a correct name them).
11828 (print_results): Invoke new_closure/free_closure if needed.
11830 2001-12-05 Akim Demaille <akim@epita.fr>
11832 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
11833 * src/closure.c, src/closure.h (itemsetsize): Rename as...
11834 (nitemset): for consistency with the rest of the project.
11836 2001-12-05 Akim Demaille <akim@epita.fr>
11838 * src/closure.c (print_closure): Improve.
11839 (closure): Use it for printing input and output.
11841 2001-12-05 Akim Demaille <akim@epita.fr>
11843 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11844 indexed by nonterminals.
11846 2001-12-05 Akim Demaille <akim@epita.fr>
11848 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

11864 2001-12-05 Akim Demaille <akim@epita.fr>
11866 * src/output.c (action_row): De-obfuscate
11867 using the good o' techniques: arrays not pointers, variable
11868 locality, BITISSET, RESETBIT etc.
11870 2001-12-05 Akim Demaille <akim@epita.fr>
11872 Pessimize the code to simplify it: from now on, all the states
11873 have a valid SHIFTS, which NSHIFTS is possibly 0.
11875 * src/LR0.c (shifts_new): Be global and move to..
11876 * src/state.c, src/state.h: here.
11877 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
11878 * src/print_graph: Adjust.

11882 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
11883 * src/conflicts.c: Use it.
11884 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11885 incorrectly ``simplified''.
11887 2001-12-05 Akim Demaille <akim@epita.fr>
11889 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11890 using the good o' techniques: arrays not pointers, variable
11891 locality, BITISSET, RESETBIT etc.
11893 2001-12-05 Akim Demaille <akim@epita.fr>
11895 * src/state.h (SHIFT_SYMBOL): New.
11896 * src/conflicts.c: Use it to deobfuscate.

11900 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
11901 (print_reductions): De-obfuscate using the good o' techniques:
11902 arrays not pointers, variable locality, BITISSET.
11904 2001-12-05 Akim Demaille <akim@epita.fr>
11906 * src/conflicts.c (print_reductions): Arrays, not pointers.

11947 2001-12-05 Akim Demaille <akim@epita.fr>
11949 * src/lalr.c (transpose): Free the memory allocated to the
11950 argument, as it is replaced by the results by the unique caller.
11951 (build_relations): Merely invoke transpose: it handles the memory
11953 Improve variable locality.
11954 Avoid variables used as mere abbreviations.
11955 (compute_lookaheads): Use arrays instead of pointers.
11957 2001-12-05 Akim Demaille <akim@epita.fr>

11973 2001-12-05 Akim Demaille <akim@epita.fr>
11975 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11976 the handling of squeue.
11977 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11979 2001-12-05 Akim Demaille <akim@epita.fr>
11981 Because useless nonterminals are now kept alive (instead of being
11982 `destroyed'), we now sometimes examine them, and store information
11983 related to them. Hence we need to know their number, and adjust
11984 memory allocations.
11986 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11988 * src/LR0.c (allocate_itemsets): The memory allocated to
11989 `symbol_count' was used for two different purpose: once to count
11990 the number of occurrences of each symbol, and later reassigned to
11991 `shift_symbol', containing the symbol that can be shifted from a
11993 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11995 (new_itemsets): Allocate `shift_symbol' here.
11996 (allocate_itemsets): symbol_count includes useless nonterminals.
11997 Make room for them.
11998 (free_storage): Use `free', not `XFREE', for pointers that cannot

12009 * src/gram.c, src/gram.h (ritem_print): New.
12010 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
12011 (This useless function was defined only to work around VMS linkers
12012 that can't handle compilation units with variables only).
12013 * src/reduce.c (dump_grammar): Use it to trace the construction of
12016 2001-12-04 Paul Eggert <eggert@twinsun.com>
12018 * src/bison.simple (union yyalloc): Change member names
12019 to be the same as the stack names.
12020 (yyparse): yyptr is now union yyalloc *, not char *.
12021 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
12022 and may generate better code on some machines.
12023 (yystpcpy): Use prototype if __STDC__ is defined, not just
12024 if __cplusplus is defined.
12026 2001-11-30 Akim Demaille <akim@epita.fr>
12028 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
12029 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
12030 Gettext doesn't compile cleanly, and dies with -Werror.
12031 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
12032 Include WARNING_CFLAGS here.
12033 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
12034 before being defined.

12038 * lib/quotearg.h (quotearg_n, quotearg_n_style):
12039 First arg is int, not unsigned.
12040 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
12041 (SIZE_MAX, UINT_MAX): New macros.
12042 (quotearg_n_options): Abort if N is negative.
12043 Avoid overflow check on hosts where size_t is 64 bits and int
12044 is 32 bits, as overflow is impossible there.
12045 Fix off-by-one typo that caused unnecessary reallocation.
12047 2001-11-29 Paul Eggert <eggert@twinsun.com>
12049 Name space cleanup in generated parser.
12051 * doc/bison.texinfo (Bison Parser): Discuss system headers
12052 and their effect on the user name space.
12054 * src/bison.simple:
12055 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
12056 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
12057 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
12059 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
12060 on user names when possible.
12062 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
12063 Simplify test for whather <alloca.h> exists.
12065 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
12067 (<stdio.h>): Include if YYDEBUG.
12069 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
12070 ! defined (yyoverflow) && ! defined (yymemcpy).
12072 (yymemcpy, yyparse): Rename local variables as needed so that
12073 they all begin with 'yy'.
12075 (yystrlen, yystpcpy): New functions.
12077 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
12080 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
12081 instead of relying on string.h functions. Use YYSTACK_ALLOC
12082 and YYSTACK_FREE instead of malloc and free.
12084 2001-11-30 Akim Demaille <akim@epita.fr>
12086 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
12087 before their first uses.

12097 if body instead of `;' to pacify GCC's warnings.
12099 2001-11-30 Akim Demaille <akim@epita.fr>
12101 Instead of mapping the LHS of unused rules to -1, keep the LHS
12102 valid, but flag the rules as invalid.
12104 * src/gram.h (rule_t): `useful' is a new member.
12105 * src/print.c (print_grammar): Adjust.
12106 * src/derives.c (set_derives): Likewise.
12107 * src/reader.c (packgram, reduce_output): Likewise.
12108 * src/reduce.c (reduce_grammar_tables): Likewise.
12109 * tests/reduce.at (Underivable Rules, Useless Rules): New.

12125 2001-11-30 Akim Demaille <akim@epita.fr>

12135 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
12136 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
12138 (union yyalloc): New type.
12139 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
12140 an arbitrary restriction on hosts where size_t is wider than int.
12142 (yyparse): Don't dump core if alloca or malloc fails; instead, report
12143 a parser stack overflow. Allocate just one block of memory for all
12144 three stacks, instead of allocating three blocks; this typically is
12145 faster and reduces fragmentation.
12147 Do not limit the number of items in the stack to a value that fits
12148 in 'int', as this is an arbitrary limit on hosts with 64-bit
12149 size_t and 32-bit int.
12151 2001-11-29 Marc Autret <autret_m@epita.fr>
12153 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
12154 of defining YYERROR_VERBOSE.

14013 introduces a guaranteed SEGV for semantic parsers.
14014 * doc/bison.texinfo: Document them.
14015 * tests/suite.at: Exercise these %options.

14027 (obstack_fgrow4): New.
14029 2000-12-20 Akim Demaille <akim@epita.fr>
14031 * src/files.c (open_files): Fix the computation of short_base_name

14117 * src/files.c (open_files): Yipee! We no longer need all the code

14147 2000-11-17 Akim Demaille <akim@epita.fr>
14149 * lib/obstack.h: Formatting changes.
14150 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
14151 prevents type checking.
14152 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
14153 cast the value to (void *): assigning a `foo *' to a `void *'

14175 Use them to declare the variables which are global or local to

14180 * acconfig.h: Remove, no longer used.
14182 2000-11-07 Akim Demaille <akim@epita.fr>
14184 * src: s/Copyright (C)/Copyright/g.
14186 2000-11-07 Akim Demaille <akim@epita.fr>
14188 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
14190 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

14212 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
14213 s/PFILE1/BISON_HAIRY/.
14214 Adjust dependencies.
14216 2000-11-03 Akim Demaille <akim@epita.fr>
14218 For some reason, this was not applied.
14220 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
14221 `unlink': it's no longer used.
14223 2000-11-03 Akim Demaille <akim@epita.fr>
14225 * src/files.c (skeleton_find): New function, eved out of...

14230 Don't use `atexit'.
14232 * src/files.c (obstack_save): New function.
14233 (done): Rename as...
14234 (output_files): this.
14235 Use `obstack_save'.
14236 * src/main.c (main): Don't use `atexit' to register `done', since
14237 it no longer has to remove tmp files, just call `output_files'
14238 when there are no errors.
14240 2000-11-02 Akim Demaille <akim@epita.fr>
14242 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
14243 `unlink': it's no longer used.
14244 * src/files.h: Formatting changes.
14246 2000-11-02 Akim Demaille <akim@epita.fr>
14248 Remove the last uses of mktemp and unlink/delete.
14250 * src/files.c (fdefines, ftable): Removed.
14251 (defines_ostack, table_obstack): New.

14277 * src/files.c (faction): Remove.
14278 (action_obstack): New.
14279 Adjust all dependencies.

14304 * src/lex.c (read_typename): New function.
14306 * src/reader.c (copy_dollar): Likewise.
14308 2000-10-16 Akim Demaille <akim@epita.fr>
14310 * src/reader.c (copy_comment2): Expect the input stream to be on
14311 the `/' which is suspected to open a comment, instead of being
14312 called after `//' or `/*' was read.
14313 (copy_comment, copy_definition, parse_union_decl, copy_action)
14314 (copy_guard): Adjust.
14316 2000-10-16 Akim Demaille <akim@epita.fr>
14318 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
14319 `read_signed_integer'.
14321 2000-10-16 Akim Demaille <akim@epita.fr>
14323 * src/reader.c (copy_dollar): New function.
14324 (copy_guard, copy_action): Use it.
14326 2000-10-16 Akim Demaille <akim@epita.fr>
14328 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
14329 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
14330 New files, from Fileutils 4.0.27.
14331 * src/main.c (printable_version): Remove.

14338 2000-10-04 Akim Demaille <akim@epita.fr>
14340 * doc/bison.texinfo: Various typos spotted by Neil Booth.
14342 2000-10-04 Akim Demaille <akim@epita.fr>
14344 When a literal string is used to define two different tokens,
14345 `bison -v' segfaults.
14346 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
14348 * tests/regression.m4: New file.
14349 Include the core of the sample provided by Piotr Gackiewicz.
14350 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
14353 2000-10-04 Akim Demaille <akim@epita.fr>
14355 * src/reader.c (parse_expect_decl): Keep `count' within the size
14359 2000-10-02 Paul Eggert <eggert@twinsun.com>
14361 * bison.s1 (yyparse): Assign the default value
14362 unconditionally, to avoid a GCC warning and make the parser a
14365 2000-10-02 Akim Demaille <akim@epita.fr>
14367 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
14370 2000-10-02 Akim Demaille <akim@epita.fr>
14372 * src/derives.c, src/print.c, src/reduce.c: To ease the
14373 translation, move some `\n' out of the translated strings.
14375 2000-10-02 Akim Demaille <akim@epita.fr>
14377 The location tracking mechanism is precious for parse error
14378 messages. Nevertheless, it is enabled only when `@n' is used in
14379 the grammar, which is a different issue (you can use it in error
14380 message, but not in the grammar per se). Therefore, there should
14381 be another means to enable it.
14383 * src/getargs.c (getargs): Support `--locations'.
14384 (usage): Report it.
14385 * src/getargs.h (locationsflag): Export it.
14386 * src/lex.c (percent_table): Support `%locations'.
14387 * src/reader.c (yylsp_needed): Remove this variable, now replaced
14388 with `locationsflag'.
14389 * doc/bison.texinfo: Document `--locations' and `%locations'.
14391 * tests/calc.m4: Test it.
14393 For regularity of the names, replace each
14394 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
14395 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
14396 In addition replace each `flag' with `_flag'.
14398 2000-10-02 Akim Demaille <akim@epita.fr>
14400 Also test parse error messages, including with YYERROR_VERBOSE.
14402 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
14404 Use it to check the computations.
14405 Use it to check `nonassoc' is honored.
14406 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
14407 `--yyerror-verbose'.
14408 (_AT_CHECK_CALC): Adjust to this option.
14409 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
14411 2000-10-02 Akim Demaille <akim@epita.fr>
14413 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14414 the latter demonstrates a flaw in the handling of non debugging
14415 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14416 was used in order to simplify:
14432 unfortunately this leads to a CPP conflict when
14433 `--name-prefix=foo' is used since it produces `#define yydebug
14436 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14437 (YYDPRINTF): New macro.
14439 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
14441 Also test `--verbose', `--defines' and `--name-prefix'.
14443 2000-10-02 Akim Demaille <akim@epita.fr>
14445 Improve the readability of the produced parsers.
14447 * src/bison.s1: Formatting changes.
14448 Improve the comment related to the `$' mark.
14449 (yydefault): Don't fall through to `yyresume': `goto' there.
14450 * src/output.c (output_parser): When the `$' is met, skip the end
14452 New variable, `number_of_dollar_signs', to check there's exactly
14453 one `$' in the parser skeleton.
14455 2000-10-02 Akim Demaille <akim@epita.fr>
14457 * lib/xstrdup.c: New file, from the fileutils.
14458 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
14459 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
14460 instead of strlen + xmalloc + strcpy.
14461 * src/symtab.c (copys): Remove, use xstrdup instead.
14463 2000-10-02 Akim Demaille <akim@epita.fr>
14465 * src/gram.h (associativity): New enum type which replaces the
14466 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
14467 `right_assoc', `left_assoc' and `non_assoc'.
14468 Adjust all dependencies.
14469 * src/reader.c: Formatting changes.
14470 (LTYPESTR): Don't define it, use it as a literal in
14471 `reader_output_yylsp'.
14472 * src/symtab.h (symbol_class): New enum type which replaces the
14473 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
14474 `sunknown', `stoken and `snterm'.
14476 2000-10-02 Akim Demaille <akim@epita.fr>
14478 * src/getargs.c (fixed_outfiles): Rename as...
14479 (yaccflag): for consistency and accuracy.
14480 Adjust dependencies.
14482 2000-10-02 Akim Demaille <akim@epita.fr>
14484 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14485 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14486 difficult and introduced a lot of core dump. It turns out that
14487 Bison used an implementation of `xmalloc' based on `calloc', and
14488 at various places it does depend upon the initialization to 0. I
14489 have not tried to isolate the pertinent places, and all the former
14490 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14491 someone should address this issue.
14493 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
14494 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

14502 Various anti-`extern in *.c' changes.
14504 * src/system.h: Include `assert.h'.
14506 2000-10-02 Akim Demaille <akim@epita.fr>
14508 * src/state.h (nstates, final_state, first_state, first_shift)
14509 (first_reduction): Move their exportation from here...
14510 * src/LR0.h: to here.
14511 Adjust dependencies.
14512 * src/getargs.c (statisticsflag): New variable.
14513 Add support for `--statistics'.
14514 Adjust dependencies.
14516 Remove a lot of now useless `extern' statements in most files.
14518 2000-10-02 Akim Demaille <akim@epita.fr>
14520 * src/LR0.h: New file.
14523 2000-10-02 Akim Demaille <akim@epita.fr>

14550 Propagate its inclusion.
14551 * src/reduce.c: Topological sort and other formatting changes.
14552 (bool, TRUE, FALSE): Move their definition to...
14553 * src/system.h: here.
14555 2000-10-02 Akim Demaille <akim@epita.fr>
14557 * src/files.c: Formatting changes.
14558 (tryopen, tryclose, openfiles): Rename as...

15628 way to specify the flags -n, -l, and -r. Also added hooks for
