3 * bootstrap (gnulib_modules): Add extensions.
4 Problem reported by Jim Meyering.
6 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10 src/system.h, src/tables.c: XFREE -> free, to accommodate
11 recent change to gnulib xalloc.h.
12 Problem reported by Jim Meyering.
14 2004-11-17 Akim Demaille <akim@epita.fr>
16 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
18 2004-10-28 Akim Demaille <akim@epita.fr>,
19 Alexandre Duret-Lutz <adl@gnu.org>
21 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
24 Use it instead of cdebug_.
25 (Parser::debug_stream, Parser::set_debug_stream): New.
26 (Parser::symprint_): Define cdebug_ for temporary backward
28 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
31 2004-11-17 Akim Demaille <akim@epita.fr>
33 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
34 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
35 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
36 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
38 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
40 * data/glr.c (yyloc_default): Remove; not used.
41 Problem reported by Frank Heckenbach.
43 2004-10-25 Akim Demaille <akim@epita.fr>
45 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
46 Introduce another definition to address simple location arrays.
47 (yyGLRStack): New member: yyerror_range.
48 (yyrecoverSyntaxError, yyparse): Update it.
49 (yyrecoverSyntaxError): Use it when shifting the error token to
50 have an accurate range, equivalent to the one computed by both
52 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
53 that column numbers start at column 0, as per GNU Coding
54 Standards, the others tests, and the doc.
55 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
56 Adjust to the above change (first column is 0).
57 And adjust the location of the "<error>", now covering the whole
60 2004-10-22 Akim Demaille <akim@epita.fr>
61 and Paul Eggert <eggert@cs.ucla.edu>
63 Remove some arbitrary limits on goto numbers and relations.
64 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
65 initial values, since they're never used.
66 (set_goto_map): ngotos is now unsigned, so test for overflow
67 by seeing whether it wraps around to zero.
68 * src/lalr.h (goto_number): Now size_t, not short int.
69 (GOTO_NUMBER_MAXIMUM): Remove.
70 * src/relation.c (relation_print, traverse, relation_transpose):
71 Check for END_NODE rather than looking at sign.
72 * src/relation.h (END_NODE): New macro.
73 (relation_node): Now size_t, not short int.
75 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
77 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
78 keyword, not an identifier. Problem reported by Baron Schwartz in
79 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
81 2004-10-11 Akim Demaille <akim@epita.fr>
83 * src/symtab.c (symbol_check_alias_consistency): Also check
84 type names, destructors, and printers.
85 Reported by Alexandre Duret-Lutz.
86 Recode the handling of associativity and precedence in terms
87 of symbol_precedence_set.
88 Accept no redeclaration at all, not even equal to the previous
91 Use it to factor redeclaration complaints.
92 (symbol_make_alias): Don't set the type of the alias, let
93 symbol_check_alias_consistency do it as for other features.
94 * src/symtab.h (symbol): Add new member prec_location, and
96 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
97 * tests/input.at (Incompatible Aliases): New.
99 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
101 .cvsignore fixes to accommodate gnulib changes,
102 and the practice of naming build directories "_build".
103 * .cvsignore: Add "_*". Sort.
104 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
105 * m4/.cvsignore: Add "*_gl.m4".
107 2004-10-06 Akim Demaille <akim@epita.fr>
109 * src/parse-gram.y (add_param): Fix the truncation of trailing
112 2004-10-05 Akim Demaille <akim@epita.fr>
114 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
115 whether the reducion was empty or not. This leaves room to
116 improve the use of YYLLOC_DEFAULT in such a case.
117 lalr1.cc is still experimental, so changing this is acceptable.
118 And finally, there are probably not many users who changed the
119 handling of locations in GLR, so changing is admissible too.
121 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
122 empty reduction, set @$ to an empty location ending the previously
124 Adjust uses to make sure the code is triggered on empty
126 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
127 expected output: empty reductions have empty locations.
129 2004-09-29 Akim Demaille <akim@epita.fr>
131 * data/lalr1.cc: Move towards a more standard C++ coding style
132 for templates: Class < T > -> Class<T>.
134 2004-09-29 Akim Demaille <akim@epita.fr>
136 * data/lalr1.cc: Reinstall the former ctor, for sake of
137 compatibility, but warn it will be removed.
138 Move towards a more standard C++ coding style (i.e., type *var ->
141 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
143 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
144 since it's less likely to work if NULs are involved in the future.
146 2004-09-27 Akim Demaille <akim@epita.fr>
148 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
150 2004-09-27 Akim Demaille <akim@epita.fr>
152 * data/lalr1.cc (b4_parse_param_decl_1): New.
153 (b4_parse_param_decl): Use it to have different names between attribute
155 (b4_cc_constructor_call): Likewise.
157 2004-09-24 Akim Demaille <akim@epita.fr>
159 * src/parse-gram.y (add_param): Strip the leading and trailing
160 blanks from a formal argument declaration.
161 (YY_LOCATION_PRINT): New.
163 2004-09-24 Akim Demaille <akim@epita.fr>
165 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
168 2004-09-24 Akim Demaille <akim@epita.fr>
170 * doc/bison.texinfo (Table of Symbols): Sort.
172 2004-09-21 Akim Demaille <akim@epita.fr>
174 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
175 the useless parentheses.
176 Suggested by Paul Eggert.
178 2004-09-20 Akim Demaille <akim@epita.fr>
180 Let the initial-action act on the look-ahead, and use it for the
181 "initial push" (corresponding to an hypothetical beginning-of-file).
182 And let lalr1.cc honor %initial-action.
184 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
186 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
187 (Parser::Parser): Remove the ctor that used to initialize it.
188 (Parser::parse): Like in the other skeletons, issue the "starting
189 parse" message before any action.
190 Honor %initial-action.
191 Initialize the stacks with the lookahead.
192 * data/yacc.c: Let $$ and @$ in %initial-action designate the
194 Push them in the stacks.
195 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
197 2004-09-20 Akim Demaille <akim@epita.fr>
199 * doc/bison.texinfo (Initial Action Decl): New.
201 2004-09-20 Akim Demaille <akim@epita.fr>
203 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
204 clearer criterion to define it.
205 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
206 When reducing on an empty RHS, use the latest stacked location as
208 yylloc is not always available.
209 * data/glr.c: Likewise.
210 Also, honor initial-actions.
212 2004-09-20 Akim Demaille <akim@epita.fr>
214 * data/yacc.c (YY_LOCATION_PRINT): New.
215 Define when we know YYLTYPE's structure, i.e., when the default
216 YYLLOC_DEFAULT is used.
217 * data/c.m4 (b4_yysymprint_generate): Use it.
218 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
220 (error_start_): Replace with...
221 (error_range_): this location array.
222 This allows to replace code relying on the implementation of
223 locations by portable code.
224 * data/yacc.c (yylerrsp): Replace with...
225 (yyerror_range): this.
226 Every time a token is popped, update yyerror_range[0], to have an
227 accurate location for the error token.
228 * data/glr.c (YY_LOCATION_PRINT): New.
229 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
231 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
232 report the location in %printers.
234 * src/scan-skel.l: Instead of abort, report error messages to ease
235 understanding skeleton scanning failures.
237 2004-09-16 Akim Demaille <akim@epita.fr>
239 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
240 (iterator, const_iterator): these, to be more in the C++ spirit.
241 Also, return reverse iterators so that when displaying the stack
242 we display its bottom first.
243 (Parser::stack_print_, Parser::reduce_print_): Match the messages
245 We should probably use vector here though.
247 2004-09-16 Akim Demaille <akim@epita.fr>
249 Have more complete shift traces.
251 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
252 to report Shifts instead of ad hoc YYDPRINTF invocations,
253 including for the error token.
254 * data/lalr1.cc (symprint_): Output the location.
255 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
256 output the location within the %printer.
257 Activate GLR tests, at least to make sure they compile properly.
258 They still don't pass though.
259 * tests/calc.at: Adjust expect verbose output, since now "Entering
260 state..." is on a different line than the "Shifting" message.
262 2004-09-08 Akim Demaille <akim@epita.fr>
264 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
265 Bison directive from the Bison file to the invocation of this
266 macro, so that these directives are passed to
267 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
268 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
269 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
270 the extra Bison directives instead of the whole series.
271 Change the grammar so that there are recoverable errors, and
272 unrecoverable errors. Now we can have the parser give up before
273 consuming the whole input. As a result we now can observe that
274 the lookahead is freed when needed.
275 Change the parser source to parse argv[1] instead of a hard coded
277 Simplify yylex, and give a value and location to EOF.
278 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
279 passed directives already coded in the file.
280 Add some tests to check the location of "error".
281 For some tests, the C++ parser is correct, and not yacc.c.
282 For other tests, they provide different, but unsatisfying, values,
283 so keep the C++ value so that at least one parser is "correct"
284 according to the test suite.
285 (Actions after errors): Remove, this is subsumed by the
286 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
288 2004-09-06 Akim Demaille <akim@epita.fr>
290 * data/lalr1.cc: Adjust the indentation of the labels.
294 2004-09-06 Akim Demaille <akim@epita.fr>
296 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
297 argument, an informative message.
298 Call YY_SYMBOL_PRINT.
299 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
300 * data/lalr1.cc (destruct_): Likewise.
301 In addition, no longer depend on b4_yysymprint_generate and
302 b4_yydestruct_generate to generate these functions, do it "by
305 2004-09-03 Akim Demaille <akim@epita.fr>
307 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
308 invoked, yydestruct the lookahead.
309 * tests/calc.at (Calculator $1): Update the expected lengths of
310 traces: there is an added line for the discarded lookahead.
311 * doc/bison.texinfo (Destructor Decl): Some rewording.
312 Define "discarded" symbols.
314 2004-09-02 Akim Demaille <akim@epita.fr>
316 * data/lalr1.cc (translate_, destruct_): No reason to be static.
318 2004-09-02 Akim Demaille <akim@epita.fr>
320 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
321 (YYDSYMPRINTF): Rename as...
322 (YY_SYMBOL_PRINT): this.
323 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
325 Use it instead of direct symprint_ calls.
326 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
329 2004-09-02 Akim Demaille <akim@epita.fr>
331 * data/lalr1.cc (b4_yysymprint_generate): New.
332 (symprint_): New member function, defined when YYDEBUG.
333 Use it consistently instead of token/nterm debugging output by
335 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
336 %printer calls to use cdebug_ when using lalr1.cc.
338 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
340 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
343 2004-08-26 Akim Demaille <akim@epita.fr>
345 * doc/bison.texinfo (Implementing Loops): Rename as...
346 (Implementing Gotos/Loops): this.
348 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
350 Adjust to latest gnulib.
351 * bootstrap (gnulib_modules): Add xalloc-die.
352 Set LC_ALL=C so that file names sort consistently.
353 Prefer the gnulib copies of gettext.m4, glibc21.m4,
354 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
355 uintmax_t.m4, ulonglong.m4.
356 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
357 po.m4 since we are now using _gl.m4 instead.
359 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
361 * src/scan-action.l: Remove. Scanning of semantic actions is
362 handled in scan-gram.l.
364 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
366 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
368 * src/location.h (struct): The file member is a uniqstr.
369 (equal_boundaries): Use UNIQSTR_EQ for comparison.
371 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
373 Fix bug with non-%union parsers that have printers or destructors,
374 which led to a Bison core dump. Reported by Peter Fales in
375 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
377 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
378 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
380 * src/output.c (symbol_destructors_output, symbol_printers_output):
382 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
383 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
384 UNION-FLAG. All callers changed.
385 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
386 Use type char, not unsigned int, when declaring an array of char;
387 this lets us remove a cast.
388 (Printers and Destructors): Add non-%union test cases.
390 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
392 * doc/bison.texinfo: Minor editorial changes, mostly to the new
393 GLR writeups. E.g., avoid frenchspacing and the future tense,
394 change "lookahead" to "look-ahead", and change "wrt" to "with
397 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
399 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
400 New sections, split off from the GLR Parsers section. Put the new
401 Simple GLR Parser near the start of the GLR section, for clarity.
402 Rewrite connective text.
404 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
406 * doc/bison.texinfo (Simple GLR Parsers): New section.
408 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
410 * NEWS, TODO, doc/bison.texinfo:
411 Use "look-ahead" instead of "lookahead", to be consistent.

442 * tests/atlocal.in (CXXFLAGS): Use it.
444 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
446 Fix some "make check" problems with C++ reported by
447 Albert Chin-A-Young for Tru64 C++ in this thread:
448 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
450 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
451 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
452 Output to a .cc file for C++, not to a .c file.

454 * tests/regression.at (AT_CHECK_DANCER): Likewise.
455 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
457 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
459 * tests/calc.at, tests/actions.at: Workaround for SGI
460 C++ compiler. (trivial change)
462 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
464 Spent a few hours checking out which prerequisite versions the
465 current sources actually require. I went all the way back to
466 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
467 a seemingly endless set of combinations of versions more recent
468 than that. The bottom line is that the current sources require
469 fairly recent versions of the build tools, and it'll be some work
471 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
472 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
473 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
474 Add comments explaining why those particular versions are
477 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
478 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
479 <http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
481 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
482 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
484 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
486 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
487 0.11.5. Suggested by Bruno Haible.
488 * bootstrap: Remove gettext version checking.
490 * doc/bison.texinfo (Decl Summary): Also mention that %union
491 can depend on prerequisite types. Problem reported by Tim
494 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
496 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
497 * README-alpha: Don't tell people not to package this.
499 * bootstrap: Don't assume $(...) works; use `...` instead.
500 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
503 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
504 put into the -d output file, and mention what to do if YYSTYPE is
507 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
509 Undo change made earlier today: it caused autopoint to not bring
510 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
513 * bootstrap: Check that gettext version matches what's in
514 configure.ac. Warn users to ignore robots.txt ERROR 404.
515 * bootstrap: Undo today's earlier change (logged below).
516 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
518 The gettext version checking is causing more trouble than it's
519 curing; remove it. Problem reported by Paul Hilfinger.
521 * bootstrap: Issue a warning that one can expect a message

595 * src/.cvsignore: Add *.output.
597 * src/parse-gram.y: Put copyright notice inside %{ %} so it
598 gets copied to the output file.
600 2004-04-28 Paul Eggert <eggert@twinsun.com>
602 Get files from the gnulib and po repositories, instead of relying
603 on them being in our CVS. Upgrade to latest versions of gnulib
606 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
607 * bootstrap: Bootstrap from gnulib and po repositories.
608 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
609 * README-cvs: Document these changes. Remove version numbers from
610 mentions of build tools, since they change so often. Mention Flex.

633 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
636 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".

732 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
733 so that this include file can stand alone.
734 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
735 does this now. Include subpipe.h first after config.h, to
736 test whether it can stand alone.
738 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
739 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the

854 2004-02-02 Paul Eggert <eggert@twinsun.com>
856 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
857 $(top_srcdir)/lib and ../lib. This fixes a bug reported
858 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
859 There's no need to mention top_builddir since Automake does that
861 (INCLUDES): Remove, as Automake says it's obsolescent.
862 Contents migrated into AM_CPPFLAGS as described above.

879 * src/output.c (output_skeleton): Rename local var.
880 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
881 Bison tokens, as this runs afoul of the 2003-10-07 change that
882 disallowed NUL bytes in character constants or string literals.
884 * tests/local.at: Require Autoconf 2.59's Autotest.
885 * tests/testsuite.at: Don't include local.at, since we now assume
886 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
888 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
889 multiple inclusion warnings.
891 2003-12-02 Akim Demaille <akim@epita.fr>

915 * doc/bison.texinfo: Document %no-default-prec only if
916 the defaultprec flag is set. Normally it's not.
918 2003-10-04 Paul Eggert <eggert@twinsun.com>
920 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
921 non-modifiable lvalue, instead of a modifiable one.
922 * doc/bison.texinfo (Actions): Document that $$ can
923 be assigned to. Do not claim that $$ and $N are
924 array element references: user code should not rely on this.
926 2003-10-01 Paul Eggert <eggert@twinsun.com>
928 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

972 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
973 (Parser::parse): here.
974 Adjust: nerrs and errstatus is now replaced by...
975 (Parser::nerrs_, Parser::errstatus_): New.
977 2003-08-25 Akim Demaille <akim@epita.fr>
979 * config/announce-gen, Makefile.cfg: New.
980 * Makefile.am: Adjust.
981 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
982 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
984 2003-08-25 Akim Demaille <akim@epita.fr>
986 When reducing initial empty rules, Bison parser read an initial
987 location that is not defined. This results in garbage, and that
988 affects Bison's own parser. Therefore we need (i) to extend Bison
989 to support a means to initialize this location, and (ii) to use
990 this CVS Bison to fix CVS Bison's parser.
992 * src/reader.h, reader.c (epilogue_augment): Remove, replace
994 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
995 * src/parse-gram.y: Adjust.
996 (%initial-action): New.
997 (%error-verbose): Since we require CVS Bison, there is no reason
999 * src/scan-gram.l: Adjust.
1000 * src/Makefile.am (YACC): New, to make sure we use our own parser.
1001 * data/yacc.c (yyparse): Use b4_initial_action.
1003 2003-08-25 Akim Demaille <akim@epita.fr>
1005 * doc/bison.texinfo: Don't promote stdout for error messages.
1007 2003-08-25 Akim Demaille <akim@epita.fr>
1009 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

1016 2003-08-25 Akim Demaille <akim@epita.fr>
1018 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
1021 2003-08-25 Akim Demaille <akim@epita.fr>
1023 * data/lalr1.cc (Parser::reduce_print_): New.
1026 2003-08-25 Akim Demaille <akim@epita.fr>
1028 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
1029 error recovery loops. This patch is based on
1030 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
1031 Also, augment the similarity between lalr1.cc and yacc.c.
1032 Note: the locations of error recovery rules are not correct yet.
1034 * data/lalr1.cc: Comment changes to augment the similarity between
1035 lalr1.cc and yacc.c.
1036 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
1037 (yyerrlab1): Remove, but where it used to be (now the bottom part of
1038 yyerrlab), when hitting EOF, pop the whole stack here instead of
1039 merely falling thru the default error handling mechanism.
1040 (yyerrorlab): New label, with the old contents of YYERROR,
1041 plus the following change: pop the stack of rhs corresponding
1042 to the production that invoked YYERROR. That is how Yacc
1043 behaves (required by POSIX).
1044 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
1047 2003-08-25 Akim Demaille <akim@epita.fr>
1049 Tune local.at so that people can "autom4te -l autotest calc.at -o
1050 calc" for instance, to extract a sub test suite.
1052 * tests/testsuite.at: Move the initialization, Autotest version
1053 requirement, and AT_TESTED invocation into...
1054 * tests/local.at: here.
1055 * tests/testsuite.at: Include it for compatibility with Autoconf
1057 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
1060 2003-08-04 Paul Eggert <eggert@twinsun.com>
1062 Rework code slightly to avoid gcc -Wtraditional warnings.
1063 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
1064 The returned value is now stored in *YY0. All callers changed.
1065 * src/output.c (merge_output): Adjust to the above change.
1067 2003-07-26 Paul Eggert <eggert@twinsun.com>
1069 * data/glr.c (YYASSERT): New macro.
1070 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
1071 yyresolveStates, yyprocessOneStack):
1072 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
1073 Derived from a suggestion by Frank Heckenbach.
1075 2003-07-25 Paul Eggert <eggert@twinsun.com>
1077 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
1078 for portability to K&R C (after ansi2knr, presumably). See
1079 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
1080 by Frank Heckenbach, though I have omitted the structure-initialization
1081 part of his glr-knr.diff patch since I recall that the Portable
1082 C Compiler didn't require that change.
1084 Let the user specify how to allocate and free memory.
1085 Derived from a suggestion by Frank Heckenbach in
1086 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
1087 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
1088 All uses of free, malloc, realloc changed to use these macros,
1089 and unnecessary casts removed.
1090 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
1092 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
1094 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
1095 use s.empty() rather than s == "" to test for empty string; see
1096 <http://mail.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
1099 2003-06-25 Akim Demaille <akim@epita.fr>
1101 * config/depcomp, config/install-sh: Update from masters.
1103 2003-06-20 Paul Eggert <eggert@twinsun.com>

1106 and return properly parenthesized result.
1107 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
1108 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
1109 Remove unnecessary parentheses from uses.

1115 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
1116 yyreportTree): Do not assume that size_t is the same width as int,
1117 when printing sizes. Print sizes using an unsigned format.
1118 Problem reported by Frank Heckenbach in
1119 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
1121 Port to Forte Developer 7 C compiler.
1122 * data/glr.c (struct YYLTYPE): If locations are not being used,
1123 declare a single dummy member, as empty structs do not conform
1125 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
1126 the Forte Developer 7 C compiler complains that end-of-loop
1127 code is not reached.
1129 2003-06-17 Paul Eggert <eggert@twinsun.com>
1131 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
1132 avoid warnings from picky compilers about redefinition of PARAMS.

1141 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
1142 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
1143 Don't use 'index' in comments, as it's a builtin fn on some hosts.
1144 * lib/bitset_stats.c: Include gettext.h unconditionally, as
1145 per recent gettext manual's suggestion.
1146 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

1165 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
1166 * lib/vbitset.c, lib/vbitset.h: New files.
1167 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
1168 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
1171 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
1172 `How Can I Reset @code{yyparse}', since texinfo does not allow
1173 arbitrary @ in node names.
1175 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
1176 shouldn't be needed according to the gettext 0.12.1 documentation
1177 but which seem to be needed anyway: codeset.m4 glibc21.m4
1178 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
1179 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

1191 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
1192 (MOSTLYCLEANFILES): New var.
1193 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
1194 (stdbool.h): New rule.

1200 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
1201 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
1202 the tests right now.
1203 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
1204 yyerror are declared before use; C99 requires this.
1206 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1208 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
1210 (yyrecoverSyntaxError): Correct the logic for setting and testing
1212 Correct comment on handling EOF.
1213 Allow states with only a default reduction, rather than failing
1214 (I can't quite reconstruct why these were not allowed before).
1216 Fixes to avoid problem that $-N rules in GLR parsers can cause
1217 buffer overruns, corrupting state.
1219 * src/output.c (prepare_rules): Output max_left_semantic_context
1221 * src/reader.h (max_left_semantic_context): New variable declaration.
1222 * src/scan-gram.l (max_left_semantic_context): Define.

1226 (yyresolveAction): Ditto.
1228 Fixes to problems with location handling in GLR parsers reported by
1229 Frank Heckenbach (2003/06/05).
1231 * data/glr.c (YYLTYPE): Make trivial if locations not used.
1232 (YYRHSLOC): Add parentheses, and define only if locations used.
1233 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if

1236 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
1238 * tests/cxx-type.at: Exercise location information; update tests
1239 to differentiate output with and without locations.
1240 Remove forward declarations of yylex and yyerror---caused errors
1241 because default YYLTYPE not yet defined.
1242 Change semantic actions to compute strings, rather than printing
1243 them directly (to test proper passing of semantics values). Change
1244 output to prefix notation and update test data and expected results.
1245 (yylex): Track locations.
1246 (stmtMerge): Return value rather than printing, and include arguments
1249 2003-06-03 Paul Eggert <eggert@twinsun.com>
1251 Avoid warnings generated by GCC 2.95.4 when Bison is
1252 configured with --enable-gcc-warnings.

1254 yy::]b4_parser_class_name[::translate_,

1257 yy::Slice::operator[] (unsigned),
1258 yy::Slice::operator[] (unsigned) const):
1259 Rename local vars to avoid warnings.
1260 * tests/glr-regression.at (Improper handling of embedded actions
1261 and $-N in GLR parsers): Remove unused local variable from yylex.
1262 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
1263 (void) as arg when not pure, since we now assume C89 when building
1264 Bison. Pacify GCC by using parameter.
1266 2003-06-02 Paul Eggert <eggert@twinsun.com>
1268 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
1269 yy::Location::lines, yy::Location::columns): Rename arguments
1270 to avoid shadowing; this removes a warning generated by GCC 3.3.
1272 2003-06-01 Paul Eggert <eggert@twinsun.com>
1274 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
1275 to g++, as GCC 3.3 complains if you do it.
1276 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
1277 everything that WARNING_CFLAGS has, except omit warnings
1278 not suitable for C++.
1279 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
1280 * tests/atlocal.in (CXXFLAGS): New var.
1281 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
1283 Fix a GLR parser bug I reported in February; see
1284 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
1285 The problem was that GLR parsers did not conform to the C standard,
1286 because actions like { $1 = $2 + $3; } expanded to expressions
1287 that invoked YYFILL in separate subexpressions, and YYFILL assigned
1288 to a local variable. The C standard says that expressions
1289 like (var = f ()) + (var = f ()) have undefined behavior.
1290 Another problem was that GCC sometimes issues warnings that
1291 yyfill and its parameters are unused.
1293 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
1295 (yyfill): New function.
1297 (yyuserAction): Change type of yynormal to bool, so that it matches
1298 the new yyfill signature. Mark it as possibly unused.
1301 Follow up on a bug I reported in February, where a Bison-generated
1302 parser can loop. Provide a test case and a fix for yacc.c. I
1303 don't have a fix for lalr1.cc or for glr.c, unfortunately.
1304 The original bug report is in:
1305 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
1307 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
1308 macro's size was becoming unwieldy.
1309 (yyerrlab): Do not discard an empty lookahead symbol, as this
1310 might destroy garbage.
1311 (yyerrorlab): New label, with the old contents of YYERROR,
1312 plus the following change: pop the stack of rhs corresponding
1313 to the production that invoked YYERROR. That is how Yacc
1314 behaves, and POSIX requires this behavior.
1315 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
1316 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
1317 Define 'alarm' to do nothing if unistd.h is not available.
1318 Add a new rule "exp: '-' error;" to test the above change to
1319 data/yacc.c. Use 'alarm' to abort any test taking longer than
1320 10 seconds, as it's probably looping.
1321 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
1322 Also, the new yacc.c generates two fewer diagnostics for an
1325 2003-05-24 Paul Eggert <eggert@twinsun.com>
1327 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
1328 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
1329 This fixes a problem reported by John Bowman when the Compaq/HP
1330 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
1332 * data/yacc.c (union yyalloc): Likewise.
1333 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
1335 Switch from 'int' to 'bool' where that makes sense.

1401 semicolon after a grammar declaration, in the interest of possible
1402 future changes to the Bison input language.
1403 Do not allow a stray semicolon at the start of the grammar.

1409 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
1411 %parse-param support for lalr1.cc.
1413 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
1414 b4_cc_constructor_calls, b4_cc_constructor_call,
1415 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
1417 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
1418 parse-param arguments.
1419 (yy::b4_parser_class_name): Declare instance variables to
1420 hold parse-param arguments.
1421 * tests/calc.at: s/value/semantic_value/ because value clashes
1422 with a member of yy::b4_parser_class_name. Adjust C++ code
1423 to handle %parse-param. Enable %parse-param test in C++.
1425 2003-05-12 Paul Eggert <eggert@twinsun.com>
1427 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
1428 English a bit. Fix fclose typo. Change "const char" to "char
1429 const", and use ANSI C rather than K&R for "main". Suggest
1430 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
1431 and suggest yy_switch_to_buffer.
1433 2003-05-05 Paul Eggert <eggert@twinsun.com>
1435 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
1436 C89. This avoids a diagnostic on compilers that define __STDC__
1437 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
1438 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
1440 2003-05-03 Paul Eggert <eggert@twinsun.com>
1442 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
1443 Do not overrun array bounds.
1444 This should fix a bug reported today by Olatunji Oluwabukunmi in
1445 <http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
1447 2003-04-29 Akim Demaille <akim@epita.fr>
1449 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
1450 * src/getargs.c, src/getargs.h: here, as bool, not int.
1451 (nondeterministic_parser): New.
1452 * src/parse-gram.y, src/scan-gram.l: Support
1453 %nondeterministic-parser.
1454 * src/output.c (prepare): Use nondeterministic_parser instead
1455 of glr_parser where appropriate.
1456 * src/tables.c (conflict_row, action_row, save_row)
1457 (token_actions, token_actions, pack_vector): Ditto.
1459 2003-04-29 Akim Demaille <akim@epita.fr>
1461 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
1463 2003-04-29 Akim Demaille <akim@epita.fr>
1465 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
1466 with %pure-parser and %locations to exercise the patch from Yakov
1469 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
1471 * data/yacc.c: (b4_lex_param): Corrected for the case where
1472 %lex-param is provided and %pure-parser isn't.
1474 2003-04-27 Paul Eggert <eggert@twinsun.com>
1476 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
1477 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
1478 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
1479 if it is not defined.
1480 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
1482 2003-04-26 Paul Eggert <eggert@twinsun.com>
1484 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
1485 Declare to be of type suitable for the ninf value itself, not of
1486 type suitable for the corresponding table, since the latter might
1487 be unsigned but the ninf value might be negative. This fixes a
1488 bug reported by Alexandre Duret-Lutz in
1489 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
1491 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
1492 invokes it. We shouldn't invoke it twice because it will attempt
1493 to put error.o in the archive twice. This fixes a glitch reported
1494 by Martin Mokrejs in
1495 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
1497 2003-04-21 Paul Eggert <eggert@twinsun.com>
1499 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
1502 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
1504 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
1505 Fix obvious typo that results in uncompilable GLR parsers
1506 when both %pure-parser and %locations are used. (trivial change)
1508 2003-04-17 Paul Eggert <eggert@twinsun.com>
1510 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
1511 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
1512 Do not insert the expected token via unput, as this runs afoul
1513 of a POSIX-compatibility bug in flex 2.5.31.
1514 All uses changed to BEGIN the parent state,
1515 since we no longer insert the expected token via unput.
1516 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
1517 that is no longer emitted after the above change.
1519 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
1520 the first one. This change is from Paul Hilfinger, and it fixes
1521 regression reported by Werner Lemberg in
1522 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
1524 (resolve_sr_conflict): Don't invoke state_errs_set
1525 unless one or more tokens have been explicitly made errors.
1526 Otherwise, the above change causes Bison to abort.
1528 * tests/existing.at (GNU pic Grammar): New test case, taken from
1531 2003-03-31 Akim Demaille <akim@epita.fr>
1533 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
1535 2003-03-31 Akim Demaille <akim@epita.fr>
1537 * src/output.c (prepare_symbols): Avoid trailing spaces in the
1540 2003-03-31 Akim Demaille <akim@epita.fr>
1542 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
1543 From Paul Hilfinger.
1545 2003-03-29 Akim Demaille <akim@epita.fr>
1547 * m4/error.m4: Do not put under dynamic conditions some code which
1548 expansion is under static control.
1550 2003-03-29 Akim Demaille <akim@epita.fr>
1552 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
1554 2003-03-29 Akim Demaille <akim@epita.fr>
1556 * doc/bison.texinfo (Strings are Destroyed): New.
1558 2003-03-13 Paul Eggert <eggert@twinsun.com>
1560 * .cvsignore: Add configure.lineno.
1561 * src/.cvsignore: Add yacc.
1562 * tests/.cvsignore: Add testsuite.log.
1563 * doc/fdl.texi: Sync with latest FSF version.
1565 2003-03-12 Paul Eggert <eggert@twinsun.com>
1567 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
1568 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
1569 cursor, instead of leaving it undefined. This fixes a bug
1570 reported by Tim Van Holder in
1571 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
1572 * tests/input.at (Torturing the Scanner): Test the scanner on
1573 an empty input file, which was Tim Van Holder's test case.
1575 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
1576 <sys/resource.h> can be included, include sys/time.h and
1577 sys/times.h first, if available. This works around the SunOS
1578 4.1.4 porting bug reported by Bruce Becker in
1579 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
1581 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
1582 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
1585 Merge changes from gnulib. This was prompted because the CVS
1586 snapshot didn't build on Solaris 7 due to strnlen problems.
1588 These changes need to be merged back into gnulib:
1589 * lib/hash.c: Include <stdbool.h> unconditionally.
1590 * m4/onceonly.m4 (m4_quote): New macro.
1591 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
1592 Quote AC_FOREACH variable-expansions properly.
1593 The 2003-01-03 obstack.h change also needs merging.
1594 {end of changes requiring merging}
1596 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
1597 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
1598 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
1599 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
1600 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
1601 New files, imported from gnulib.
1602 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
1605 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
1606 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
1609 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
1611 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
1612 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
1613 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
1614 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
1615 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
1616 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
1617 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
1618 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
1619 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
1620 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
1621 (jm_PREREQ_ARGMATCH): Remove.
1622 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
1623 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
1625 * src/system.h: Include <stdbool.h> unconditionally.
1627 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
1628 assuming at least C89 in the bitset code for some time now.
1630 2003-03-03 Akim Demaille <akim@epita.fr>
1634 2003-03-02 Akim Demaille <akim@epita.fr>
1636 * doc/bison.texinfo (Table of Symbols): Reactivate the
1637 documentation for %lex-param, and %parse-param.
1639 2003-03-02 Akim Demaille <akim@epita.fr>
1641 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
1642 generate verbose error messages.
1643 Use the number of tokens as an upper bound in yytname, as it
1644 cannot be a non terminal.
1646 2003-03-02 Akim Demaille <akim@epita.fr>
1648 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
1651 2003-03-02 Akim Demaille <akim@epita.fr>
1653 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
1654 Use them to exercise yycheck overrun.
1655 Based on Andrew Suffield's grammar.
1657 2003-03-02 Akim Demaille <akim@epita.fr>
1659 Create tests/local.at for Bison generic testing macros.
1661 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
1662 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
1664 * tests/calc.at (AT_CHECK_CALC): Adjust.
1665 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
1666 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
1667 * tests/local.at: here.
1668 (AT_COMPILE_CXX): Tags the tests using it as c++.
1669 Ignore the test if CXX is not functional.
1671 2003-03-01 Paul Eggert <eggert@twinsun.com>
1673 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
1674 not loc->end, since loc->end might contain garbage and this leads
1675 to undefined behavior on some platforms.
1676 (id_loc, token_start): Use (IF_LINTed) initial values that do not
1677 depend on *loc, so that the reader doesn't give the the false
1678 impression that *loc is initialized.
1679 (<INITIAL>"%%"): Do not bother setting code_start, since its value
1680 does not survive the return.
1682 2003-03-01 Akim Demaille <akim@epita.fr>
1684 * src/scan-gram.l (code_start): Always initialize it when entering
1685 into yylex, as SC_EPILOGUE is activated *before* the corresponding
1686 yylex invocation. An alternative would be making it static, but
1687 then it starts with the second %%'s beginning, instead of its end.
1689 2003-02-28 Paul Eggert <eggert@twinsun.com>
1691 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
1692 around a UnixWare 7.1.1 porting bug reported by John Hughes in
1693 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
1695 2003-02-26 Paul Eggert <eggert@twinsun.com>
1697 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
1698 Remove Sequent/Pyramid discussion (nobody uses them any more).
1699 Merge VMS and MS-DOS discussion; these ports may well be dead
1700 but let's keep mentioning them for now. Put <> around email
1701 addresses. Add copyright notice.
1703 2003-02-24 Paul Eggert <eggert@twinsun.com>
1705 * data/glr.c (yy_reduce_print): yylineno -> yylno,
1706 to avoid collision with flex use of yylineno.
1707 Problem reported by Bruce Lilly in
1708 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

1717 change integer types.
1718 Suggested by Paul Eggert.
1720 2003-02-21 Akim Demaille <akim@epita.fr>
1722 * doc/bison.texinfo: Use "location" consistently to refer to @n,
1723 to avoid confusions with lalr1.cc's notion of Position.
1724 Suggested by Paul Eggert.
1726 2003-02-20 Akim Demaille <akim@epita.fr>
1728 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
1729 before initial_columns.
1730 (location.hh): Use consistent variable names when defining the
1732 Use "last" so that we subtract from Positions, not from unsigned.
1734 2003-02-20 Akim Demaille <akim@epita.fr>
1736 * data/lalr1.cc (position.hh): New subfile, including the extended
1737 and Doxygen'ed documentation of class Position.
1738 (location.hh): Use it.
1739 Document a` la Doxygen.
1740 With the help of Benoit Perrot.
1742 2003-02-20 Akim Demaille <akim@epita.fr>
1744 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
1746 Redefine AT_YYERROR_SEES_LOC_IF using it.
1747 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
1749 Don't use the location in yy::Parser::error_ and
1750 yy::Parser::print_ when not %locations.
1751 Activate more lalr1.cc tests.
1753 2003-02-19 Akim Demaille <akim@epita.fr>
1755 * data/lalr1.cc: When displaying a line number, be sure to make it
1758 2003-02-19 Akim Demaille <akim@epita.fr>
1760 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
1762 (YYABORT, YYACCEPT, YYERROR): New.
1763 * tests/calc.at: Renable the lalr1.cc test.
1765 2003-02-19 Akim Demaille <akim@epita.fr>
1767 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
1768 error recovery, mixing with/without pops and discarding of the
1771 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
1773 2003-02-17 Paul Eggert <eggert@twinsun.com>
1775 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
1776 * tests/testsuite.at (AT_COMPILE): Use them.
1777 This fixes the testsuite problem reported by Robert Lentz in
1778 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
1780 2003-02-12 Paul Eggert <eggert@twinsun.com>
1782 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
1783 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in

1786 Check for malloc failure, for consistency with yacc.c.
1787 (yytname_size): Remove, for consistency with yacc.c.
1789 The bug still remains in data/lalr1.cc, as I didn't have time
1792 2003-02-06 Akim Demaille <akim@epita.fr>
1794 * configure.ac (GXX): Rename as...
1795 (CXX): this, to keep the original Autoconf semantics.
1797 * data/lalr1.cc: Fix b4_copyright invocations.
1798 If YYDEBUG is not defined, don't depend upon name_ being defined.

1810 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
1811 locations in a more synthetic way.
1812 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
1814 Adjust the C locations to match those from Emacs: first column is
1816 Change all the expected results.
1817 Conform to the GCS: simplify the locations when applicable.
1818 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
1819 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
1820 these CPP macros with the m4 macros new defined by...
1821 (AT_CHECK_PUSHDEFS): this, i.e.:

1881 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
1883 * src/uniqstr.h: Likewise.
1885 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
1886 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
1887 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
1888 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
1889 param to have same name as that of enum, so that we don't use
1890 "s" to stand for a non-state.
1892 2003-02-02 Akim Demaille <akim@epita.fr>
1894 * src/scan-skel.l: Scan more than one inert character per yylex
1897 2003-02-01 Paul Eggert <eggert@twinsun.com>
1901 * po/LINGUAS: Add ms.
1903 2003-01-30 Akim Demaille <akim@epita.fr>
1905 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
1907 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1909 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
1912 Changes in response to error report by S. Eken: GLR mode does not
1913 handle negative $ indices or $ indices in embedded rules correctly.
1914 See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
1916 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
1917 (b4_rhs_location): Ditto.
1918 (yyfill): New function to copy from stack tree into array
1920 (yyuserAction): Modify to allow incremental move of semantic values
1921 to rhs array when in GLR mode.
1922 Define YYFILL to use in user-defined actions to fill semantic array
1924 Remove dummy use of yystack, as there is now a guaranteed use.
1925 (yydoAction): Modify to allow incremental move of semantic values
1926 to rhs array when in GLR mode.
1927 (yyresolveAction): Ditto.
1928 (yyglrShiftDefer): Update comment.
1929 (yyresolveStates): Use X == NULL for pointers, not !X.
1930 (yyglrReduce): Ditto.
1933 * tests/glr-regr1.at: Rename to ...
1934 * tests/glr-regression.at: Add new regression test for the problems
1935 described above (adapted from S. Eken).
1936 Update copyright notice.
1937 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
1938 * tests/Makefile.am: Ditto.
1940 2003-01-28 Paul Eggert <eggert@twinsun.com>
1942 * data/lalr1.cc: Do not use @output_header_name@ unless
1943 b4_defines_flag is set. This fixes two bugs reported by
1945 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
1946 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
1948 2003-01-21 Paul Eggert <eggert@twinsun.com>
1950 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
1951 we don't need to worry about yyerrlab1 being reported as an
1952 "unused label" by non-GCC C compilers. The downside is that if
1953 locations are used then a couple of statements are duplicated each
1954 time YYERROR is invoked, but the upside is that the warnings
1956 (yyerrlab1): Move code to YERROR.
1957 (yyerrlab2): Remove. Change uses back to yyerrlab1.
1958 This reverts some of the 2002-12-27 change.
1960 2003-01-17 Paul Eggert <eggert@twinsun.com>
1962 * src/output.c (symbol_printers_output): Fix typo that led
1963 to core dump. Problem reported by Antonio Rus in
1964 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
1966 2003-01-13 Akim Demaille <akim@epita.fr>,
1967 Quoc Peyrot <chojin@lrde.epita.fr>,
1968 Robert Anisko <anisko_r@lrde.epita.fr>
1970 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
1971 when the stacks contain one element, as the loop would otherwise
1972 free the last state, and then use the top state (the one we just
1973 popped). This means that the initial elements will not be freed
1974 explicitly, as is the case in yacc.c; it is not a problem, as
1975 these elements have fake values.
1977 2003-01-11 Paul Eggert <eggert@twinsun.com>
1979 * NEWS: %expect-violations are now just warnings, reverting
1980 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
1981 bootstrapping problem reported by Matthias Klose; see
1982 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
1983 * src/conflicts.c (conflicts_print): Likewise.
1984 * tests/conflicts.at (%expect not enough, %expect too much,
1985 %expect with reduce conflicts): Likewise.
1986 * doc/bison.texinfo (Expect Decl): Document this. Also mention
1987 that the warning is enabled if the number of conflicts changes
1988 (not necessarily increases).
1990 * src/getargs.c (version): Update copyright year.
1992 2003-01-09 Akim Demaille <akim@epita.fr>
1994 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
1996 2003-01-08 Paul Eggert <eggert@twinsun.com>
1998 * Makefile.maint (WGETFLAGS):
1999 New macro, containing "-C off" to disable proxy caches.
2000 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
2001 (rel-check): Use $(WGET) instead of wget.
2003 2003-01-06 Paul Eggert <eggert@twinsun.com>
2005 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
2006 the GLR paper of Scott, Johnstone and Hussain.
2008 2003-01-04 Paul Eggert <eggert@twinsun.com>
2010 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
2011 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
2012 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
2013 (EXTRA_LIBRARIES): New var, for liby.a.
2014 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
2015 (EXTRA_SCRIPTS): New var, for yacc.
2017 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
2018 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
2019 Problem reported by Nelson H. F. Beebe.
2021 2003-01-03 Paul Eggert <eggert@twinsun.com>
2023 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
2024 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
2025 when compiling Bison 1.875's `bitset bset = obstack_alloc
2026 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
2028 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
2029 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
2030 grow to a huge size with typical invocation.
2032 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
2033 Use the pattern recommended by Autoconf 2.57, except also protect
2034 against double-definition.
2035 * src/system.h: Likewise.
2036 Portability issues reported by Nelson H. F. Beebe.
2038 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
2039 All uses changed. Provide a definition in both C and C++.
2040 (yytrue, yyfalse): Define even if defined (__cplusplus).
2042 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
2043 Reported by Nelson H. F. Beebe.
2045 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
2047 2003-01-02 Paul Eggert <eggert@twinsun.com>
2049 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
2050 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
2051 Bug reported by Nelson H. F. Beebe.
2053 2003-01-01 Paul Eggert <eggert@twinsun.com>
2057 2002-12-30 Paul Eggert <eggert@twinsun.com>
2059 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
2061 (<INITIAL>","): Here. This causes stray "," to be treated
2064 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
2065 last brace in braced code when not in Yacc mode, for compatibility
2066 with Bison 1.35. This resurrects the 2001-12-15 patch to
2069 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
2070 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
2072 2002-12-28 Paul Eggert <eggert@twinsun.com>
2074 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
2075 that of SYM's type. This fixes Debian bug 168069, reported by
2078 2002-12-28 Paul Eggert <eggert@twinsun.com>
2082 Switch back to the Yacc style of conflict reports, undoing some
2083 of the 2002-07-30 change.
2084 * doc/bison.texinfo (Understanding): Use Yacc style for
2085 conflict reports. Also, use new way of locating rules.
2086 * src/conflicts.c (conflict_report):
2087 Renamed from conflict_report_yacc, removing the old
2088 'conflict_report'. Translate the entire conflict report at once,
2089 so that we don't assume that "," has the same interpretation in
2091 (conflicts_output): Use Yacc-style conflict report for each state,
2092 instead of our more-complicated style.
2093 (conflicts_print): Use Yacc-style conflict report, except print
2094 the input file name when not emulating Yacc.
2095 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
2096 Conflicted Reduction, %expect not enough, %expect too much,
2097 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
2098 * tests/existing.at (GNU Cim Grammar): Likewise.
2099 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
2101 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
2102 fatal): Don't invoke fflush; it's not needed and it might even be
2103 harmful for stdout, as stdout might not be open.
2104 * src/reduce.c (reduce_print): Likewise.
2106 2002-12-27 Paul Eggert <eggert@twinsun.com>
2108 Fix a bug where error locations were not being recorded correctly.
2109 This problem was originally reported by Paul Hilfinger in
2110 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
2112 * data/yacc.c (yyparse): New local var yylerrsp, to record the
2113 top of the location stack's error locations.
2114 (yyerrlab): Set it. When discarding a token, push its location
2115 onto yylerrsp so that we don't lose track of the error's end.
2116 (yyerrlab1): Now is only the target of YYERROR, so that we can
2117 properly record the location of the action that failed. For GCC
2118 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
2119 GCC warning about yyerrlab1 being unused if YYERROR is unused.
2120 (yyerrlab2): New label, which yyerrlab now falls through to.
2121 Compute the error's location by applying YYLLOC_DEFAULT to
2122 the locations of all the symbols that went into the error.
2123 * doc/bison.texinfo (Location Default Action): Mention that
2124 YYLLOC_DEFAULT is also invoked for syntax errors.
2125 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
2126 Error locations include the locations of all the tokens that were
2127 discarded, not just the last token.
2129 2002-12-26 Paul Eggert <eggert@twinsun.com>
2131 * src/files.c: Include quote.h.
2132 (compute_output_file_names): Warn if we detect conflicting
2133 outputs to the same file. This should catch the misunderstanding
2134 exemplified by Debian Bug 165349, reported by Bruce Stephens..
2136 * src/conflicts.c (conflicts_print): If the user specifies
2137 "%expect N", report an error if there are any reduce/reduce
2138 conflicts. This is what the manual says should happen.
2139 This fixes Debian bug 130890, reported by Anthony DeRobertis.
2140 * tests/conflicts.at (%expect with reduce conflicts): New test.
2142 Don't use m4_include on relative file names, as it doesn't work as
2143 desired if there happens to be a file with that name under ".".
2145 * m4sugar/version.m4: Remove; it was included but it wasn't used.
2146 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
2147 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
2148 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
2149 * src/output.c (output_skeleton): Use full path names when
2150 specifying a file to include; don't rely on include path, as
2151 it's unreliable when the working file contains a file with
2154 2002-12-25 Paul Eggert <eggert@twinsun.com>
2156 Remove obsolete references to bison.simple and bison.hairy.
2157 Problem mentioned by Aubin Mahe in
2158 <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
2159 * data/glr.c: Comment fix.
2160 * doc/bison.1: Remove references. Also, mention "yacc".
2162 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
2165 * src/parse-gram.y (declaration): Use enum "report_states" rather
2166 than its numeric value 1.
2168 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
2169 opening a new one. This fixes Debian bug 165349, reported by
2172 2002-12-24 Paul Eggert <eggert@twinsun.com>
2176 * Makefile.maint (cvs-update): Don't assume that the shell
2177 supports $(...), as Solaris sh doesn't.
2179 * src/parse-gram.y (lloc_default): Remove test for empty
2180 nonterminals at the end, since it didn't change the result.
2182 2002-12-24 Paul Eggert <eggert@twinsun.com>
2184 If the user does not define YYSTYPE as a macro, Bison now declares it
2185 using typedef instead of defining it as a macro. POSIX requires this.
2186 For consistency, YYLTYPE is also declared instead of defined.
2188 %union directives can now have a tag before the `{', e.g., the
2189 directive `%union foo {...}' now generates the C code
2190 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
2191 The default union tag is `YYSTYPE', for compatibility with Solaris 9
2192 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
2193 instead of `yyltype'.
2195 `yystype' and `yyltype' are now obsolescent macros instead of being
2196 typedefs or tags; they are no longer documented and will be
2197 withdrawn in a future release.
2199 * data/glr.c (b4_location_type): Remove.
2200 (YYSTYPE): Renamed from yystype.
2201 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
2202 (struct YYLTYPE): Renamed from struct yyltype.
2203 (YYLTYPE): Renamed from yyltype.
2204 (yyltype, yystype): New (and obsolescent) macros,
2205 for backward compatibility.
2206 * data/yacc.c: Likewise.
2208 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
2209 does not specify a union tag. This is for compatibility with
2212 * src/parse-gram.y (add_param): 2nd arg is now char * not char
2213 const *, since it is now modified by stripping surrounding { }.
2214 (current_braced_code): Remove.
2215 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
2216 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
2217 trailing " {...}". Now of type <chars>.
2218 (grammar_declaration): Adjust to bundled tokens.
2219 (code_content): Remove; stripping is now done by add_param.
2220 (print_token_value): Print contents of bundled tokens.
2221 (token_name): New function.
2223 * src/reader.h (braced_code, current_braced_code): Remove.
2224 (token_name): New decl.
2226 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
2227 token_type, not braced_code code_kind. All uses changed.
2228 (SC_PRE_CODE): New state, for scanning after a keyword that
2229 has (or usually has) an immediately-following braced code.
2230 (token_type): New local var, to keep track of which token type
2231 to return when scanning braced code.
2232 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
2233 <INITIAL>"%parse-param", <INITIAL>"%printer",
2234 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
2235 instead of returning a token type immediately.
2236 (<INITIAL>"{"): Set token type.
2237 (<SC_BRACED_CODE>"}"): Use it.
2238 (handle_action_dollar, handle_action_at): Now returns bool
2239 indicating success. Fail if ! current_rule; this prevents a core dump.
2240 (handle_symbol_code_dollar, handle_symbol_code_at):
2241 Remove; merge body into caller.
2242 (handle_dollar, handle_at): Complain in invalid contexts.
2244 * NEWS, doc/bison.texinfo: Document the above.
2245 * NEWS: Fix years and program names in copyright notice.
2247 2002-12-17 Paul Eggert <eggert@twinsun.com>
2249 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
2250 Reporting, Table of Symbols): Omit mentions of %lex-param and
2251 %parse-param from the documentation for now.
2253 2002-12-15 Paul Eggert <eggert@twinsun.com>
2255 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
2256 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
2257 lookahead symbol, and which sets yychar in parser actions) and it
2258 disagreed with the Bison documentation. Bug
2259 reported by Andrew Walrond.
2261 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
2262 as the caller now does that.
2263 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
2264 (YYEMPTY): Parenthesize right hand side, since others use it.
2265 (yyparse): Don't assume that our generated code is the only code
2268 2002-12-13 Paul Eggert <eggert@twinsun.com>
2272 POSIX requires a "yacc" command.
2273 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
2274 (MOSTLYCLEANFILES): Add yacc.
2276 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
2277 as an alias for bison y.
2279 * po/LINGUAS: Add da.
2281 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
2282 problem with latest <getopt.h>.
2283 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
2285 * doc/fdl.texi: Upgrade to 1.2.
2286 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
2287 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
2288 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
2290 * config/install-sh: Sync with autotools.
2292 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
2293 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
2294 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
2295 locations are requested.
2296 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
2297 locations are requested.
2299 2002-12-12 Paul Eggert <eggert@twinsun.com>
2301 Remove unportable casts and storage allocation tricks.
2302 While we're at it, remove almost all casts, since they
2303 usually aren't needed and are a sign of trouble.
2305 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
2307 * src/derives.c (derives_compute): Do not subtract NTOKENS from
2308 the pointer DSET returned by malloc; this isn't portable.
2309 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
2310 Similarly for DERIVES.
2311 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
2312 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
2313 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
2315 * src/derives.c (derives_compute): Do not bother invoking
2316 int_of_rule_number, since rule numbers are integers.
2318 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
2319 rather than XMALLOC (char, N).
2321 * src/files.c (filename_split): Rewrite to avoid cast.
2323 * src/gram.h (symbol_number_as_item_number,
2324 item_number_as_symbol_number, rule_number_as_item_number,
2325 item_number_as_rule_number):
2326 Now inline functions rather than macros, to avoid casts.
2327 * src/state.h (state_number_as_int): Likewise.
2328 * src/tables.c (state_number_to_vector_number,
2329 symbol_number_to_vector_number): Likewise.
2331 * src/gram.h (int_of_rule_number): Remove; no longer used.
2333 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
2334 since the resulting storage is always stored into.
2336 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
2339 * src/muscle_tab.c (muscle_m4_output):
2340 Now inline. Return bool, not int.
2341 * src/state.c (state_compare): Likewise.
2342 * src/symtab.c (symbol_check_defined,
2343 symbol_check_alias_consistency, symbol_pack, symbol_translation,
2344 hash_compare_symbol, hash_symbol):
2346 * src/uniqstr.c (uniqstr_print): Likewise.
2347 * src/muscle_tab.c (muscle_m4_output_processor):
2348 New function, to avoid casts.
2349 * src/state.c (state_comparator, stage_hasher): Likewise.
2350 * src/symtab.c (symbol_check_defined_processor,
2351 symbol_check_alias_consistency_processor, symbol_pack_processor,
2352 symbol_translation_processor, hash_symbol_comparator,
2353 hash_symbol_hasher): Likewise.
2354 * src/uniqstr.c (uniqstr_print_processor): Likewise.
2355 * src/muscle_tab.c (muscles_m4_output):
2356 Use new functions instead of casting old functions unportably.
2357 * src/state.c (state_hash_new): Likewise.
2358 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
2359 symbols_token_translations_init):
2361 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
2363 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local

2373 STATE_ALLOC): Remove.
2374 (transitions_new, errs_new, reductions_new, state_new): Use malloc

2379 * src/state.c (state_hash): Use unsigned accumulator, not signed.
2381 * src/symtab.c (symbol_free): Remove; unused.

2387 (symbol_processor): Remove.
2388 (symbols_do): Remove decl; now static.
2390 * src/system.h (alloca): Remove; decl no longer needed.
2391 (<stddef.h>): Include, for offsetof.
2392 (<inttypes.>, <stdint.h>): Include if available.
2393 (uintptr_t): New type, if system lacks it.

2404 * src/vcg.h: Correct misspellings.
2406 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
2409 * src/getargs.c (getargs): Don't assume EOF == -1.
2411 2002-12-09 Paul Eggert <eggert@twinsun.com>
2413 Change identifier spellings to avoid collisions with names
2414 that are reserved by POSIX.
2416 Don't use names ending in _t, since POSIX reserves them.
2417 For consistency, remove _e and _s endings -- they're weren't
2418 needed to remove ambiguity. All uses changed.
2419 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
2420 turn was just renamed from struniq_t.
2421 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
2422 which in turn was just renamed from struniq_processor_t.

2494 value_t_as_yystype -> value_as_yystype.
2496 Don't include <errno.h> in the mainstream code, since it
2497 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
2498 * lib/get-errno.c, lib/get-errno.h: New files.
2499 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

2508 * src/system.h: Do not include <errno.h>.
2509 (TAB_EXT): Renamed from EXT_TAB.
2510 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
2512 Avoid str[a-z]*, since <string.h> reserves that name space.
2513 Change all instances of "struniq" in names to "uniqstr", and
2514 likewise for "STRUNIQ" and "UNIQSTR".
2515 * src/uniqstr.c: Renamed from src/struniq.c.
2516 * src/uniqstr.h: Renamed from src/struniq.h.

2527 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
2528 (N_EXPAND): Renamed from N_STRETCH.

2552 for consistency with other names.
2553 * lib/timevar.h (timevar_report): New decl.
2554 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
2557 Sort include-file uses.
2559 Reorder all include files under src to be in the order "system.h".
2560 then the ../lib include files in angle brackets (alphabetized),
2561 then the . include files in double-quotes (alphabetized). Fix
2562 dependency breakages encountered in this process, as follows:
2563 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
2564 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
2565 * src/state.h: Include "symtab.h".
2567 2002-12-08 Paul Eggert <eggert@twinsun.com>
2569 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
2570 since this causes problems when __file__ contains character
2571 sequences like "@" that are treated specially by src/scan-skel.l.
2572 Instead, just use the file's basename. This fixes the bug
2573 reported by Martin Mokrejs in
2574 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
2576 2002-12-06 Paul Eggert <eggert@twinsun.com>
2578 Add support for rules that do not have trailing semicolons, as
2579 POSIX requires. Improve the quality of locations in Bison
2582 * src/location.c: Include <quotearg.h>.
2583 (empty_location): Now const.
2584 (location_print): New function. Follow the recommendation of the
2585 GNU Coding Standards for locations that span file boundaries.
2586 * src/location.h: Do not include <quotearg.h>; no longer needed.
2587 (boundary): New type.
2588 (location_t): Use it. This allows locations to span file boundaries.
2589 All member uses changed: file -> start.file or end.file (as needed),
2590 first_line -> start.line, first_column -> start.column,
2591 last_line -> end.line, last_column -> end.column.
2592 (equal_boundaries): New function.
2593 (LOCATION_RESET, LOCATION_STEP): Remove.
2594 (LOCATION_PRINT): Remove. All callers changed to use location_print.
2595 (empty_location): Now const.
2596 (location_print): New decl.
2597 * src/parse-gram.y (lloc_default): New function, which handles
2598 empty locations more accurately.
2599 (YYLLOC_DEFAULT): Use it.
2600 (%token COLON): Remove.
2601 (%token ID_COLON): New token.
2603 (declarations, rules): Remove trailing semicolon.
2604 (declaration, rules_or_grammar_declaration):
2605 Allow empty (";") declaration.
2606 (symbol_def): Remove empty actions; no longer needed.
2607 (rules_or_grammar_declaration): Remove trailing semicolon.
2608 (semi_colon.opt): Remove.
2609 * src/reader.h: Include location.h.
2610 (scanner_cursor): New decl.
2611 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
2613 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
2615 (STEP): Remove. No longer needed, now that adjust_location does
2616 the work. All uses removed.
2617 (scanner_cursor): New var.
2618 (adjust_location): Renamed from extend_location. It now sets
2619 *loc and adjusts the scanner cursor. All uses changed.
2620 Don't bother testing for CR.
2621 (handle_syncline): Remove location arg; now updates scanner cursor.
2622 All callers changed.
2623 (unexpected_end_of_file): Now accepts start boundary of token or
2624 comment, not location. All callers changed. Update scanner cursor,
2626 (SC_AFTER_IDENTIFIER): New state.
2627 (context_state): Renamed from c_context. All uses changed.
2628 (id_loc, code_start, token_start): New local vars.
2629 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
2630 processing of Yacc white space and equivalents here.
2631 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
2632 instead of returning ID immediately, since we need to search for
2634 (<INITIAL>"'", "\""): Save token_start.
2635 (<INITIAL>"%{", "{", "%%"): Save code_start.
2636 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
2637 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
2638 BEGIN context_state at end, not INITIAL.
2639 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
2640 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
2641 Return correct token start.
2642 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
2643 the start of a character, string or multiline comment is found.
2644 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
2645 Reduction): Adjust reported locations to match the more-precise
2646 results now expected.
2647 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
2648 * tests/reduce.at (Useless Rules, Reduced Automaton,
2649 Underivable Rules): Likewise.
2650 * tests/regression.at (Invalid inputs): No longer `expecting ";"
2651 or "|"' now that so many other tokens are allowed by the new grammar.
2653 * src/complain.h (current_file): Remove duplicate decl;
2654 current_file is now owned by files.h.
2655 * src/complain.c, src/scan-gram.l: Include files.h.
2657 2002-12-06 Paul Eggert <eggert@twinsun.com>
2659 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
2660 promotes to int; it might be unsigned int.
2661 * data/yacc.c (yy_reduce_print): Likewise.
2663 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
2664 be #defined in the prologue, not in the Bison declarations.
2665 This fixes Debian Bug 102878, reported by Shaul Karl.
2667 2002-12-02 Paul Eggert <eggert@twinsun.com>
2669 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
2670 * lib/strtoul.c: New file, from gnulib.
2671 This fixes a porting bug reported by Peter Klein in
2672 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
2674 2002-11-30 Paul Eggert <eggert@twinsun.com>
2676 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
2677 and put only a forward declaration in the prologue. This is for
2678 consistency with the other scanner helper functions.
2680 Type clashes now generate warnings, not errors, since it
2681 appears that POSIX may allow some grammars with type clashes.
2682 * src/reader.c (grammar_current_rule_check): Warn about
2683 type clashes instead of complaining.
2684 * tests/input.at (Type Clashes): Expect warnings, not complaints.
2686 Add Yacc library, since POSIX requires it.
2687 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
2688 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
2689 * lib/main.c, lib/yyerror.c: New files.
2691 gram_error can be static; it need not be extern.
2692 * src/reader.h (gram_error): Remove decl.
2693 * src/parse-gram.y (gram_error): Now static. Add static decl.
2694 (print_token_value): Omit parameter names from forward decl,
2697 2002-11-29 Paul Eggert <eggert@twinsun.com>
2699 * doc/bison.texinfo: Emphasize that yylex and yyerror must
2700 be declared before being used. E.g., one should typically
2701 declare them in the prologue. Use GNU coding style in examples.
2702 Put "const" consistently after the type it modifies. Mention
2703 that C99 supports "inline". Mention that yyerror traditionally
2706 %parse-param and %lex-param now take just one argument, the
2707 declaration; the argument name is deduced from the declaration.
2709 * doc/bison.texinfo (Parser Function, Pure Calling, Error
2710 Reporting, Table of Symbols): Document this.
2711 * src/parse-gram.y (add_param): New function.
2713 (declaration): Implement new rule for %parse-param and %lex-param.
2714 * src/scan-gram.l: "," now elicits a warning, rather than being
2715 a token; this is more compatible with byacc.
2716 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
2718 2002-11-27 Paul Eggert <eggert@twinsun.com>
2720 Rename identifiers to avoid real and potential collisions.
2722 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
2723 to avoid collision with lex macro described by Bruce Lilly in
2724 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
2725 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
2726 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
2727 * src/parse-gram.y (print_token_value): Renamed from yyprint.
2729 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
2730 The name "yycontrol" violates the name space rules, and this stuff
2731 wasn't being used anyway.
2732 (input): Remove action; this stuff wasn't being used.
2733 (gram_error): Rename local variable yylloc -> loc.
2734 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
2735 (YY_DECL): Don't use "yy" at start of local variables.
2736 All uses changed, e.g., yylloc -> loc.
2737 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
2738 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
2739 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
2740 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
2742 * src/parse-gram.y (gram_error): loc is now const *.
2743 * src/reader.h (gram_error): Likewise.
2745 2002-11-24 Paul Eggert <eggert@twinsun.com>
2749 * tests/actions.at (Actions after errors): Use an output format
2750 more similar to that of the Printers and Destructors test.
2751 Test the position of the ';' token too.
2752 (Printers and Destructors): Likewise.
2753 (Printers and Destructors: %glr-parser): Remove for now, to avoid
2754 unnecessarily alarming people when the test fails.
2756 * data/yacc.c (yyerrlab1): Move this label down, so that the
2757 parser does not discard the lookahead token if the user code
2758 invokes YYERROR. This change is required for POSIX conformance.
2760 * lib/error.c: Sync with gnulib.
2762 2002-11-22 Paul Eggert <eggert@twinsun.com>
2764 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
2765 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
2766 * lib/xmalloc.c: Likewise.
2768 2002-11-20 Paul Eggert <eggert@twinsun.com>
2770 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
2772 2002-11-20 Paul Eggert <eggert@twinsun.com>
2774 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
2775 should use `if (! x) abort ();' rather than `assert (x);', and
2776 anyway it's one less thing to worry about configuring.
2778 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
2779 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
2780 and replace all instances of assert with abort.
2781 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
2782 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
2784 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
2785 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
2786 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
2787 hash_find_entry, hash_rehash, hash_insert): Likewise.
2788 * src/conflicts.c (resolve_sr_conflict): Likewise.
2789 * src/lalr.c (set_goto_map, map_goto): Likewise.
2790 * src/nullable.c (nullable_compute): Likewise.
2791 * src/output.c (prepare_rules, token_definitions_output): Likewise.
2792 * src/reader.c (packgram, reader): Likewise.

2796 symbol_pack): Likewise.
2797 * src/tables.c (conflict_row, pack_vector): Likewise.
2798 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
2799 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
2800 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
2801 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
2803 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
2804 (ARGMATCH_CONSTRAINT): New macro.
2805 (ARGMATCH_ASSERT): Use it.
2807 * src/system.h (verify): New macro.
2808 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
2810 * src/tables.c (tables_generate): Likewise.
2812 * src/struniq.c (struniq_assert): Now returns void, and aborts
2813 if the assertion is false.
2814 (struniq_assert_p): Remove.
2815 * src/struniq.h: Likewise.
2817 2002-11-18 Paul Eggert <eggert@twinsun.com>
2819 * data/glr.c (yygetLRActions): Replace `yyindex' with
2820 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
2821 This fixes the regression with Sun ONE Studio 7 cc that I reported in
2822 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
2824 2002-11-18 Akim Demaille <akim@epita.fr>
2826 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
2828 From Tim Van Holder.
2830 2002-11-17 Paul Eggert <eggert@twinsun.com>
2832 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
2833 to "SyntaxError" for consistency with my 2002-11-15 change.
2835 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
2836 not define to {}, since this breaks the common use of `YYDPRINTF
2837 ((...));' if a single statement is desired (e.g. before `else').
2838 Work around GCC warnings by surrounding corresponding calls with
2840 (yyhasResolvedValue): Remove unused function.
2841 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
2843 (yyreportSyntaxError): Renamed from yyreportParseError.
2844 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
2846 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
2847 extern when possible. Remove unused initializations.
2849 2002-11-16 Akim Demaille <akim@epita.fr>
2851 Augment the similarity between GLR and LALR traces.
2853 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
2854 (YY_REDUCE_PRINT): New.
2855 (yyparse): Use them.
2856 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
2858 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
2859 state reached after the reduction/recovery, since...
2860 (yyparse, yyprocessOneStack): Report the state we are entering in.
2862 2002-11-16 Akim Demaille <akim@epita.fr>
2864 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
2865 Add support for --trace=skeleton.
2866 * src/scan-skel.l: %option debug.
2867 Scan strings of non-@ or \n instead of character by character.
2868 (scan_skel): Handle trace_skeleton.
2870 (@output_parser_name@, @output_header_name@): ``Restore'' their
2871 support (used to be M4 macros).
2872 * data/yacc.c: Quote larger chunks, a la glr.c.
2873 * data/lalr1.cc: Likewise.
2874 The header guards are no longer available, so use some other
2875 string than `YYLSP_NEEDED'.
2877 2002-11-16 Akim Demaille <akim@epita.fr>
2879 Make the ``Printers and Destructors'' test more verbose, taking
2880 `yacc.c''s behavior as (possibly wrong) reference.
2882 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
2883 instead of fprint on stdout.
2884 Set and report the last_line of the symbols.
2885 Consistently display values and locations.
2887 2002-11-16 Paul Eggert <eggert@twinsun.com>
2889 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
2891 2002-11-15 Paul Eggert <eggert@twinsun.com>
2893 * tests/actions.at (Actions after errors): New test case.
2895 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
2896 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
2897 tests/action.at, tests/calc.at, tests/conflicts.at,
2898 tests/cxx-type.at, tests/regression.at:
2899 "parse error" -> "syntax error" for POSIX compatibility.
2900 "parsing stack overflow..." -> "parser stack overflow" so
2901 that code matches Bison documentation.
2903 2002-11-15 Akim Demaille <akim@epita.fr>
2905 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
2906 take two BRACED_CODE, not two string_content.
2907 Free the scanner's obstack when we are done.
2908 (code_content): New.
2909 * tests/calc.at: Adjust.
2910 * doc/bison.texinfo: Adjust.
2911 Also, make sure to include the `,' for these declarations.
2913 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
2915 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
2916 definition; avoids potential autoreconf problems.
2918 2002-11-15 Akim Demaille <akim@epita.fr>
2920 Always check the value returned by yyparse.
2922 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
2923 returned by yyparse.
2924 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
2926 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
2927 returned by yyparse.
2929 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
2931 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
2934 2002-11-14 Paul Eggert <eggert@twinsun.com>
2936 * src/output.c (output_skeleton): Call xfopen instead of
2937 duplicating xfopen's body.
2939 Fix bugs reported by Nelson H. F. Beebe in
2940 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
2942 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
2943 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
2944 Group compiler. Instead, use "$CC -E bar.c". Include the .h
2945 file twice in the grammar, as an extra check.
2947 * tests/input.at (Torturing the Scanner): Surround the
2948 backslash-newline tests with "#if 0", to make it less likely that
2949 we'll run into compiler bugs. Bring back solitary \ inside
2950 comment, but add a closing comment to work around HP C bug. Don't
2951 test backslash-newline in C character constant.
2953 2002-11-14 Akim Demaille <akim@epita.fr>
2955 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
2956 status of the compiler.
2957 Calling `exit 1' is no longer needed.
2958 Reported by Nelson H. F. Beebe.
2960 2002-11-14 Akim Demaille <akim@epita.fr>
2962 * tests/atlocal.in (CPPFLAGS): We have config.h.
2963 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
2965 * tests/actions.at, tests/calc.at, tests/conflicts.at,
2966 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
2967 * tests/regression.at, tests/torture.at: Use them for all the
2968 grammars that are to be compiled.
2969 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
2970 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
2971 * doc/bison.texinfo (GLR Parsers): Document `inline'.
2973 2002-11-14 Akim Demaille <akim@epita.fr>
2975 * doc/bison.texinfo: Various formatting changes (alignments in
2976 samples, additional @group/@end group, GCS in samples.
2977 Use @deffn instead of simple @table to define the directives,
2978 macros, variables etc.
2980 2002-11-13 Paul Eggert <eggert@twinsun.com>
2982 Fix some bugs reported by Albert Chin-A-Young in
2983 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
2985 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
2986 -o c"; the HP C compiler chatters during compilation.
2987 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
2988 * tests/headers.at (export YYLTYPE): Likewise.
2990 * tests/input.at (Torturing the Scanner): Remove lines containing
2991 solitary backslashes, as they tickle a bug in the HP C compiler.
2993 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
2994 comments, since they're not portable. Use GNU coding style.
2996 2002-11-13 Akim Demaille <akim@epita.fr>
2998 * data/yacc.c: Leave bigger chunks of quoted text.
2999 (YYDSYMPRINTF): New.
3000 Use it to report symbol activities.
3001 * data/glr.c (YYDSYMPRINTF): New.
3004 2002-11-12 Paul Eggert <eggert@twinsun.com>
3008 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
3009 (yyglrReduce): Return yyok, not 0.
3010 This should avoid the enumerated-type warnings reported
3011 by Nelson H. F. Beebe in
3012 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
3014 * lib/bbitset.h (BITSET_INLINE): Remove.
3015 * lib/bitset.h [! BITSET_INLINE]: Remove.
3016 (bitset_set, bitset_reset, bitset_test): Rename local vars
3017 to avoid shadowing warnings by GCC.
3019 * data/glr.c (inline): Remove #define. It's the user's
3020 responsibility to #define it away, just like 'const'.
3021 This fixes one of the bugs reported by Nelson H. F. Beebe in
3022 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
3024 * Makefile.maint (po-check): Scan .l and .y files instead of the
3025 .c and the .h files that they generate. This fixes the bug
3026 reported by Tim Van Holder in:
3027 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
3028 Look for N_ as well as for _. Try to avoid matching #define for
3030 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
3031 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
3032 * src/scan-gram.l: Revamp regular expressions so that " and '
3033 do not confuse xgettext.
3035 * src/struniq.h (struniq_new): Do not declare the return type
3036 to be 'const'; this violates the C standard.
3037 * src/struniq.c (struniq_new): Likewise.
3039 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
3041 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
3042 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
3045 2002-11-12 Akim Demaille <akim@epita.fr>
3047 * Makefile.maint: Sync with Autoconf:

3064 2002-11-12 Akim Demaille <akim@epita.fr>
3066 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
3067 Use it to test the GLR parser.
3069 2002-11-12 Akim Demaille <akim@epita.fr>
3071 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
3073 * data/glr.c (yystos): New.
3074 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
3076 (yyval): Don't define it, it is handled via M4.
3077 (yyrecoverParseError): Free verbosely the discarded symbols.
3078 * data/yacc.c (yysymprint): Remove, rather...
3079 (b4_yysymprint_generate): invoke.
3080 * data/c.m4 (b4_yysymprint_generate): New.
3081 Accept pointers as arguments, as opposed to the version from
3083 (b4_yydestruct_generate): Likewise.
3084 * tests/cations.at (Printers and Destructors): Use Bison directives
3085 instead of CPP macros.
3086 Don't rely on internal details.
3088 2002-11-12 Akim Demaille <akim@epita.fr>
3090 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
3091 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
3092 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
3093 it against YYEMPTY and so forth), work on yytoken (i.e., set
3094 it to YYEMPTY etc.).
3095 (yydestruct): Replace with a b4_yydestruct_generate invocation.
3096 (b4_symbol_actions): Remove.
3097 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
3098 for 0, end-of-input.
3100 2002-11-12 Akim Demaille <akim@epita.fr>
3102 * doc/bison.texinfo (Destructor Decl): New.
3104 2002-11-12 Akim Demaille <akim@epita.fr>
3106 * src/tables.c (tables_generate): Use free for pointers that
3107 cannot be NULL, not XFREE.
3108 (pack_vector): Use assert, not fatal, for bound violations.
3109 * src/state.c (state_new): Likewise.
3110 * src/reader.c (reader): Likewise.
3111 * src/lalr.c (set_goto_map): Likewise.
3112 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
3115 2002-11-12 Akim Demaille <akim@epita.fr>
3117 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
3119 * src/scan-gram.l (last_string): Is global to the file, not to
3121 * src/parse-gram.y (input): Don't append the epilogue here,
3122 (epilogue.opt): do it here, and free the scanner's obstack.
3123 * src/reader.c (epilogue_set): Rename as...
3124 (epilogue_augment): this.
3125 * data/c.m4 (b4_epilogue): Defaults to empty.

3135 2002-11-12 Akim Demaille <akim@epita.fr>
3137 * src/struniq.h, src/struniq.c (struniq_t): Is const.
3138 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
3140 Use struniq for symbols.
3142 * src/symtab.h (symbol_t): The tag member is a struniq.
3143 (symbol_type_set): Adjust.

3145 (symbol_free): Don't free the tag member.
3146 (hash_compare_symbol_t, hash_symbol_t): Rename as...
3147 (hash_compare_symbol, hash_symbol): these.
3148 Use the fact that tags as struniqs.

3183 2002-11-11 Paul Eggert <eggert@twinsun.com>
3185 Revamp to fix many (but not all) of the C- and M4-related quoting
3186 problems. Among other things, this fixes the Bison bug reported
3187 by Jan Hubicka when processing the Bash grammar; see:
3188 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
3190 Use new @ escapes consistently. Represent brackets with @{ and @}
3191 rather than @<:@ and @:>@, since this works a bit better with dumb
3192 editors like vi. Represent @ with @@, since @ is now consistently
3193 an escape. Use @oline@ and @ofile@ rather than __oline__ and
3194 __ofile__, to avoid unexpected expansions. Similarly, use @output
3195 rather than #output.
3197 * data/c.m4 (b4_copyright): Omit file name from comment, since
3198 the file name could contain "*/".
3199 (b4_synclines_flag): Don't quote the 2nd argument; it should already
3200 be quoted. All uses changed.
3202 * data/glr.c: Use new @ escapes consistently.
3203 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
3204 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
3205 Remove, since they couldn't handle arbitrary characters in file
3207 * data/lalr1.cc: Likewise.
3208 * data/yacc.c: Likewise.
3210 * src/files.c (output_infix): Remove; all uses removed.
3211 * src/files.h: Likewise.
3213 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
3214 mishandled funny characters in file names, and anyway it isn't
3216 * data/yacc.c: Likewise.
3217 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
3219 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
3220 * data/yacc.c: Likewise.
3222 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
3224 (muscle_init): Quote filename as a C string.
3225 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
3226 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
3227 * src/output.c (escaped_file_name_output): New function.
3228 (prepare_symbols): Quote tokens for M4.
3229 (prepare): Don't insert output_infix, output_prefix,
3230 output_parser_name, output_header_name; this is now down by scan-skel.
3231 Insert skeleton as a C string.
3233 * src/output.c (user_actions_output, symbol_destructors_output,
3234 symbol_printers_output): Quote filenames for C and M4.
3235 * src/reader.c (prologue_augment, epilogue_set): Likewise.
3237 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
3238 escapes other than \\ and \'; this simplifies the code.
3239 (<SC_STRING>): Likewise, for \\ and \".
3240 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
3241 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
3242 Use new escapes @{ and @} for [ and ].
3244 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
3245 them with auto vars.
3246 Switch to new escape scheme, where @ is the escape character uniformly.
3247 Abort if a stray escape character is found. Avoid unbounded input
3248 buffer when parsing non-escaped text.
3250 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
3251 __oline__, #output, $@, and @{ do not have unintended meanings.
3253 2002-11-09 Paul Eggert <eggert@twinsun.com>
3255 Fix the test failure due to GCC warnings described in
3256 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
3257 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
3258 evaluate to 0 if it's impossible for NINF to be in the respective
3260 (yygetLRActions, yyrecoverParseError): Use them.
3262 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
3263 counted in the token inserted at end of file. Now takes
3264 location_t *, not location_t, so that the location can be
3265 adjusted. All uses changed.
3267 * tests/regression.at (Invalid inputs): Adjust wording in
3268 diagnostic to match the new behavior.
3270 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
3271 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
3272 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
3273 abort ();'. This reduces the runtime of the "Many lookaheads"
3274 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

3279 * src/parse-gram.y (CHARACTER): Remove unused token.
3282 * src/scan-gram.l: Remove stack option. We no longer use the
3283 stack, since the stack was never deeper than 1; instead, use the
3284 new auto var c_context to record the stacked value.
3286 Remove nounput option. At an unexpected end of file, we now unput
3287 the minimal input necessary to end cleanly; this simplifies the
3290 Avoid unbounded token sizes where this is easy.
3292 (unexpected_end_of_file): New function.
3293 Use it to systematize the error message on unexpected EOF.
3294 (last-string): Now auto, not static.

3299 not the (never otherwised-used) CHARACTER.
3301 2002-11-07 Akim Demaille <akim@epita.fr>
3303 Let yyerror always receive the msg as last argument, so that
3304 yyerror can be variadic.
3306 * data/yacc.c (b4_yyerror_args): New.
3307 Use it when calling yyerror.
3308 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

3367 Initialize to zero if the compiler is being picky.
3368 (INITIAL): Clear braces_level instead of incrementing it.

3370 as POSIX 1003.1-2001 requires.
3371 * src/system.h (IF_LINT): New macro, taken from coreutils.
3372 * configure.ac: Define "lint" if --enable-gcc-warnings.
3374 2002-11-05 Akim Demaille <akim@epita.fr>
3376 * src/scan-gram.l: When it starts with `%', complain about the

3393 2002-11-04 Akim Demaille <akim@epita.fr>
3395 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
3397 * src/scan-gram.l: Use [\'] instead of ['] to pacify
3400 Use quote, not quote_n since LOCATION_PRINT no longer uses the
3403 2002-11-03 Paul Eggert <eggert@twinsun.com>
3405 * src/reader.c (get_merge_function, grammar_current_rule_check):
3406 Use consistent diagnostics for reporting type name clashes.
3407 Quote the types with <>, for consistency with Yacc.
3408 * tests/input.at (Type Clashes): Adjust to diagnostic changes.

3421 Use b4_identification.
3422 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
3423 b4_user_formals and b4_user_args.
3424 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
3425 (yyreportAmbiguity): When using a pure parser, also need
3426 the location, and the parse-params.
3428 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
3429 When using a pure parser, also need the parse-params.
3431 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
3432 (%pure-parser + %parse-param) LALR and GLR parsers.
3433 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
3434 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
3435 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.

3452 2002-11-03 Paul Eggert <eggert@twinsun.com>
3454 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
3455 to count columns correctly, and to check for invalid inputs.
3457 Use mbsnwidth to count columns correctly. Account for tabs, too.
3459 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
3460 (extend_location): New function.
3463 Handle CRLF in C code rather than in Lex code.

3467 Scan UCNs, even though we don't fully handle them yet.
3468 (convert_ucn_to_byte): New function.
3470 Handle backslash-newline correctly in C code.
3471 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
3472 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;

3475 Use {splice} wherever C allows backslash-newline.
3476 YY_STEP after space, newline, vertical-tab.
3477 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
3479 (letter, id): Don't assume ASCII; e.g., spell out a-z.
3481 ({int}, handle_action_dollar, handle_action_at): Check for integer
3484 (YY_STEP): Omit trailing semicolon, so that it's more like C.
3486 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
3487 as well as \000. Check for UCHAR_MAX, not 255.
3488 Allow \x with an arbitrary positive number of digits, as in C.
3489 Check for overflow here.
3490 Allow \? and UCNs, for compatibility with C.
3492 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
3493 with quote slot used by complain_at.
3495 * tests/input.at: Add tests for backslash-newline, m4 quotes
3496 in symbols, long literals, and funny escapes in strings.
3498 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
3499 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

3512 2002-11-02 Paul Eggert <eggert@twinsun.com>
3514 * src/reader.c: Don't include quote.h; not needed.
3515 (get_merge_function): Reword warning to be consistent with
3516 type clash diagnostic in grammar_current_rule_check.

3519 bug in trigraph handling.
3521 * src/output.c (prepare_symbols): When printing token names,
3522 escape "[" as "@<:@" and likewise for "]".
3524 * src/system.h (errno): Remove declaration, as we are now
3525 assuming C89 or better, and C89 guarantees errno.
3527 2002-10-30 Paul Eggert <eggert@twinsun.com>
3529 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
3530 Check for close failures.
3531 * src/files.h (xfclose): Return void, not int, since it always
3533 * src/files.c (xfclose): Likewise. Report I/O error if ferror
3535 * src/output.c (output_skeleton): Use xfclose rather than fclose
3536 and ferror. xfclose now checks ferror.
3538 * data/glr.c (YYLEFTMOST_STATE): Remove.
3539 (yyreportTree): Use a stack-based leftmost state. This avoids
3540 our continuing battles with bogus warnings about initializers.
3542 2002-10-30 Akim Demaille <akim@epita.fr>
3544 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

3553 2002-10-24 Paul Eggert <eggert@twinsun.com>
3557 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
3558 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
3559 we use malloc. Don't assume 'A' through 'Z' are contiguous.
3560 Don't assume strdup exists; POSIX says its an XSI extension.
3561 Check for buffer overflow on input.
3563 2002-10-24 Akim Demaille <akim@epita.fr>
3565 * src/output.c (output_skeleton): Don't disable M4sugar comments
3566 too soon: it results in comments being expanded.
3567 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
3570 2002-10-24 Akim Demaille <akim@epita.fr>
3572 * data/yacc.c (m4_int_type): New.
3573 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
3574 char' as only yacc.c wants K&R portability.

3576 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
3577 Reported by Quoc Peyrot.
3579 2002-10-23 Paul Eggert <eggert@twinsun.com>
3581 * src/main.c (main): With --trace=time, report times even if a
3582 non-fatal error occurs. Formerly, the times were reported in some
3583 such cases but not in others.
3584 * src/reader.c (reader): Just return if a complaint has been issued,
3585 instead of exiting, so that 'main' can report times.
3587 2002-10-22 Akim Demaille <akim@epita.fr>
3589 * src/system.h: Include sys/types.
3590 Reported by Bert Deknuydt.
3592 2002-10-23 Paul Eggert <eggert@twinsun.com>
3594 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
3595 Suggested by Art Haas.

3599 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
3600 decl; not needed any more.
3601 * src/main.c (main): Use return to exit, undoing yesterday's change.
3602 The last OS that we could find where this wouldn't work is
3603 SunOS 3.5, and that's too old to worry about now.
3605 * data/glr.c (struct yyltype): Define members even when not
3606 doing locations. This is more consistent with yacc.c, and it
3607 works around the following bug reports:
3608 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
3609 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
3611 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
3612 @acronym consistently. Standardize on "Yacc" instead of "YACC",
3613 "Algol" instead of "ALGOL". Give a bit more history about BNF.
3615 2002-10-22 Akim Demaille <akim@epita.fr>
3619 2002-10-21 Paul Eggert <eggert@twinsun.com>
3621 Be consistent about 'bool'; the old code used an enum in one
3622 module and an int in another, and this violates the C standard.
3623 * m4/stdbool.m4: New file, from coreutils 4.5.3.
3624 * configure.ac (AC_HEADER_STDBOOL): Add.
3625 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
3626 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
3627 * src/symtab.c (hash_compare_symbol_t): Likewise.
3628 * src/system.h (bool, false, true): Use a definition consistent
3629 with ../lib/hash.c. All uses changed.
3631 * src/complain.c (warning_issued): Renamed from warn_message_count,
3632 so that we needn't worry about integer overflow (!).
3633 Now of type bool. All uses changed.
3634 (complaint_issued): Renamed from complain_message_count; likewise.
3636 * src/main.c (main): Use exit to exit with failure.
3638 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
3639 rather than 1 and 0.
3640 * src/main.c (main): Likewise.
3641 * src/getargs.c (getargs): Likewise.
3642 * src/reader.c (reader): Likewise.
3644 * src/getarg.c (getargs): Remove duplicate code for
3645 "Try `bison --help'".
3647 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
3648 What was that "2" for?
3650 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
3651 * src/getargs.c (usage): Likewise.
3653 * src/getargs.c (getargs): When there are too few operands, report
3654 the last one. When there are too many, report the first extra
3655 one. This is how diffutils does it.
3657 2002-10-20 Paul Eggert <eggert@twinsun.com>
3659 Remove K&R vestiges.
3660 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
3661 * src/complain.c (VA_START): Remove. Assume prototypes.
3662 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
3663 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
3664 fatal): Assume prototypes.
3665 * src/complain.h: Assume prototypes.
3666 * src/system.h (PARAMS): Remove.
3667 Include <limits.h> unconditionally, since it's guaranteeed even
3668 for a freestanding C89 compiler.
3669 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
3670 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
3672 2002-10-20 Akim Demaille <akim@epita.fr>
3674 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
3675 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
3676 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
3677 (yyresolveStates, yyresolveAction, yyresolveStack)
3678 (yyprocessOneStack): Use them.
3679 (yy_reduce_print): New.

3687 (b4_c_function_def): this.
3688 (b4_c_function_decl, b4_c_ansi_function_def)
3689 (b4_c_ansi_function_decl): New.
3690 Change the interpretation of the arguments: before `int, foo', now
3692 * data/yacc.c (yyparse): Prototype and define thanks to these.
3693 Adjust b4_c_function_def uses.
3694 * data/glr.c (yyparse): Likewise, but ANSI only.
3696 2002-10-20 Akim Demaille <akim@epita.fr>
3698 * src/output.c (prepare): Move the definition of `tokens_number',
3699 `nterms_number', `undef_token_number', `user_token_number_max'
3701 (prepare_tokens): Here.
3702 (prepare_tokens): Rename as...
3703 (prepare_symbols): this.
3704 (prepare): Move the definition of `rules_number' to...
3705 (prepare_rules): here.
3706 (prepare): Move the definition of `last', `final_state_number',
3707 `states_number' to...
3708 (prepare_states): here.
3709 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
3711 2002-10-20 Akim Demaille <akim@epita.fr>
3713 * src/tables.h, src/tables.c, src/output.c: Comment changes.
3715 2002-10-20 Akim Demaille <akim@epita.fr>

3720 2002-10-20 Akim Demaille <akim@epita.fr>
3722 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
3723 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
3725 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
3727 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
3728 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
3731 2002-10-19 Paul Eggert <eggert@twinsun.com>
3733 Do not create a temporary file, as that involves security and
3734 cleanup headaches. Instead, use a pair of pipes.
3735 Derived from a suggestion by Florian Krohm.
3736 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
3737 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
3738 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
3739 (BISON_PREREQ_SUBPIPE): Add.
3740 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

3744 * src/output.c: Include "subpipe.h".
3745 (m4_invoke): Remove decl.
3746 (scan_skel): New decl.
3747 (output_skeleton): Use pipe rather than temporary file for m4 input.
3748 Check that m4sugar.m4 is readable, to avoid deadlock.
3749 Check for pipe I/O error.
3750 * src/scan-skel.l (readpipe): Remove decl.
3751 (scan_skel): New function, to be used in place of m4_invoke.
3752 Read from stream rather than file.
3754 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
3755 float, as this generates a warning on Solaris 8 + GCC 3.2 with
3756 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
3757 this generates a more-accurate value anyway.
3759 * lib/timevar.c (timervar_accumulate): Rename locals to
3760 avoid confusion with similarly-named more-global.
3761 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
3763 * src/output.c (prepare): Use xstrdup to convert char const *
3764 to char *, to avoid GCC warning.
3766 2002-10-19 Akim Demaille <akim@epita.fr>
3768 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
3769 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
3770 Use them to have `calc.y' ready for %pure-parser.
3771 * data/yacc.c (YYLEX): Pass a yylex return type to
3774 2002-10-19 Akim Demaille <akim@epita.fr>
3776 Prototype support of %lex-param and %parse-param.
3778 * src/parse-gram.y: Add the definition of the %lex-param and
3779 %parse-param tokens, plus their rules.
3780 Drop the `_' version of %glr-parser.
3782 * src/scan-gram.l (INITIAL): Scan them.
3783 * src/muscle_tab.c: Comment changes.
3784 (muscle_insert, muscle_find): Rename `pair' as `probe'.

3786 (muscle_entry_s): The `value' member is no longer const.
3787 Adjust all dependencies.
3788 * src/muscle_tab.c (muscle_init): Adjust: use
3789 MUSCLE_INSERT_STRING.
3790 Initialize the obstack earlier.
3791 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
3792 (muscle_pair_list_grow): New.
3793 * data/c.m4 (b4_c_function_call, b4_c_args): New.
3794 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.

3798 2002-10-19 Akim Demaille <akim@epita.fr>
3800 * src/getargs.c (usage): Take status as argument and exit
3802 Report the traditional `Try ... --help' message when status != 0.
3803 (usage, version): Don't take a FILE * as arg, it is pointless.
3804 (getargs): When there is an incorrect number of arguments, make it
3805 an error, and report it GNUlically thanks to `usage ()'.
3807 2002-10-18 Paul Eggert <eggert@twinsun.com>
3809 * data/glr.c (yyreportParseError): Don't assume that sprintf
3810 yields the length of the printed string, as this is not true
3811 on SunOS 4.1.4. Reported by Peter Klein.
3813 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
3814 * tests/conflicts.at (%nonassoc and eof): Likewise.
3815 Fixes SunOS 4.1.4 test failure reported by Peter Klein.

3820 * src/getargs.c (trace_types, trace_args): Adjust.
3821 * src/reader.c (grammar_current_rule_prec_set)
3822 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
3823 Standardize error messages.
3825 (reader): Use trace_flag to enable scanner/parser debugging,
3826 instead of an adhoc scheme.
3827 * src/scan-gram.l: Remove trailing debugging code.
3829 2002-10-16 Paul Eggert <eggert@twinsun.com>
3831 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
3834 * NEWS: Officially drop support for building Bison with K&R C,
3835 since it didn't work anyway and it's not worth worrying about.
3836 * Makefile.maint (wget_files): Remove ansi2knr.c.
3837 (ansi2knr.c-url_prefix): Remove.
3838 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

3842 2002-10-15 Paul Eggert <eggert@twinsun.com>
3844 Stop using the "enum_" trick for K&R-style function definitions;
3845 it confused me, and I was the author! Instead, assume that people
3846 who want to use K&R C compilers (when using these modules in GCC,
3847 perhaps?) will run ansi2knr.
3849 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.

3939 tests/cxx-type.at, tests/headers.at, tests/input.at,
3940 tests/regression.at, tests/synclines.at, tests/torture.at:
3941 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
3942 so that the tests still work even if POSIXLY_CORRECT is set.
3943 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
3945 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
3946 for portability to K&R hosts. Fix typo: signed char is guaranteed
3947 only to 127, not to 128.
3948 * data/glr.c (yysigned_char): New type.
3949 * data/yacc.c (yysigned_char): Likewise.
3950 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
3952 2002-10-13 Paul Eggert <eggert@twinsun.com>
3954 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
3955 true due to limited range of data type" warning from GCC.
3957 * data/c.m4 (b4_token_defines): Protect against double-inclusion
3958 by wrapping enum yytokentype's definition inside #ifndef
3959 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
3961 2002-10-13 Akim Demaille <akim@epita.fr>
3963 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
3964 Un yy- yyrhs to avoid the name clash with the global YYRHS.
3966 2002-10-13 Akim Demaille <akim@epita.fr>
3968 * Makefile.maint: Update from Autoconf 2.54.
3969 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
3971 2002-10-13 Akim Demaille <akim@epita.fr>
3973 * src/print.c (print_state): Separate the list of solved conflicts
3974 from the other items.

3979 Let nondeterministic skeletons be usable with deterministic
3982 With the patch, GAWK compiled by GCC without -O2 passes its test
3983 suite using a GLR parser driven by LALR tables. It fails with -O2
3984 because `struct stat' gives two different answers on my machine:
3985 88 (definition of an auto var) and later 96 (memset on this var).
3986 Hence the stack is badly corrumpted. The headers inclusion is to
3987 blame: if I move the awk.h inclusion before GLR's system header
3988 inclusion, the two struct stat have the same size.
3990 * src/tables.c (pack_table): Always create conflict_table.
3991 (token_actions): Always create conflict_list.
3992 * data/glr.c (YYFLAG): Remove, unused.
3994 2002-10-13 Akim Demaille <akim@epita.fr>
3996 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
3998 (VALGRIND, GXX): New.

4008 Tweak some trace messages to match yacc.c's.
4010 2002-10-13 Akim Demaille <akim@epita.fr>
4012 GLR parsers sometimes raise parse errors instead of performing the
4014 Reported by Charles-Henry de Boysson.
4016 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
4017 check the length of the traces when %glr.
4018 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
4020 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
4022 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
4023 (yyltype): Remove the yy prefix from the member names.
4024 (yytable): Complete its comment.
4025 (yygetLRActions): Map error action number from YYTABLE from
4027 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
4028 (which was a bug: it should have been YYTABEL_NINF, and yet it was
4029 not satisfying as we could compare an YYACTION computed from
4030 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
4031 only value for error actions.
4032 (yyreportParseError): In verbose parse error messages, don't issue
4033 `error' in the list of expected tokens.
4034 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
4035 next action to perform to match glr.c's decoding.
4036 (yytable): Complete its comment.

4042 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
4043 because the Bison parser reads the second action before reducing
4045 * src/scan-gram.l (rule_length): New static var.
4046 Use it to keep track of the rule length in the scanner, since
4047 we can't expect the parser to be in lock-step sync with the scanner.
4048 (handle_action_dollar, handle_action_at): Use this var.
4049 * tests/actions.at (Exotic Dollars): Test for the problem.
4051 2002-10-12 Paul Eggert <eggert@twinsun.com>

4057 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
4058 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
4060 * lib/timevar.c: Update copyright date and clarify comments.
4061 (get_time) [IN_GCC]: Keep the GCC version for reference.
4063 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
4064 GCC version as of today, then merge Bison's changes.
4065 Change "GCC" to "Bison" in copyright notice. timevar.def's
4066 author is Akim, so change that too.
4068 * src/reader.c (grammar_current_rule_check):
4069 Don't worry about the default action if $$ is untyped.
4070 Prevents bogus warnings reported by Jim Gifford in
4071 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
4073 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
4074 * data/glr.c, data/lalr1.cc, data/yacc.c:
4075 Output token definitions before the first part of user declarations.
4076 Fixes compatibility problem reported by Jim Gifford for kbd in

4203 which was inadvertently undone by the 2002-09-30 patch.

4560 to minimize the number of warnings from xgettext.
4561 (handle_action_dollar, handle_action_at): Don't use isdigit,

4563 outside the C locale.

4566 this is a GCC extension and is not portable to other compilers.
4568 * src/system.h (alloca): Use same pattern as ../lib/error.c.
4569 Do not include <ctype.h>; no longer needed.

4805 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
4806 for the time being: %locations ought to provide it to yyerror.
4808 2002-07-25 Akim Demaille <akim@epita.fr>
4810 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

7205 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
7206 which have no values.
7208 2002-02-05 Akim Demaille <akim@epita.fr>
7210 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
7213 2002-01-29 Paul Eggert <eggert@twinsun.com>
7215 * src/bison.simple (YYSIZE_T): Do not define merely because
7216 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
7217 On some platforms, <alloca.h> does not declare YYSTD (size_t).
7219 2002-01-27 Akim Demaille <akim@epita.fr>
7221 Fix `%nonassoc and eof'.
7223 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
7224 which were not properly copied! Replace
7225 memcpy (res->errs, src->errs, src->nerrs);
7227 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
7229 * tests/regression.at (%nonassoc and eof): Adjust to newest
7230 Autotest: `.' is not in the PATH.
7232 2002-01-27 Akim Demaille <akim@epita.fr>
7234 * tests/sets.at (AT_EXTRACT_SETS): New.
7238 2002-01-26 Akim Demaille <akim@epita.fr>
7240 * tests/actions.at, tests/calc.at, tests/headers.at,
7241 * tests/torture.at: Adjust to the newest Autotest which no longer
7242 forces `.' in the PATH.
7244 2002-01-25 Akim Demaille <akim@epita.fr>
7246 * tests/regression.at (%nonassoc and eof): New.
7247 Suggested by Robert Anisko.
7249 2002-01-24 Akim Demaille <akim@epita.fr>
7251 Bison dumps core when trying to complain about broken input files.
7252 Reported by Cris van Pelt.
7254 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
7255 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
7257 (Invalid inputs): Strengthen: exercise parse_percent_token.
7259 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
7261 * src/Makefile.am: Add bison.c++.
7262 * src/bison.c++: New skeleton.
7264 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
7268 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
7270 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
7272 2002-01-20 Marc Autret <marc@gnu.org>
7274 * src/files.c (compute_output_file_names): Fix
7276 2002-01-20 Marc Autret <marc@gnu.org>
7278 * tests/output.at: New test.
7279 * src/files.c (compute_base_names): Don't map extensions when
7280 the YACC flag is set, use defaults.
7281 Reported by Evgeny Stambulchik.
7283 2002-01-20 Marc Autret <marc@gnu.org>
7285 * src/system.h: Need to define __attribute__ away for non-GCC
7286 compilers as well (i.e. the vendor C compiler).
7287 Suggested by Albert Chin-A-Young.
7289 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
7291 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
7292 canonical definition.
7293 * src/system.h: Use the canonical definition for PARAMS (avoids
7294 a conflict with the macro from lib/hash.h).
7296 2002-01-11 Akim Demaille <akim@epita.fr>
7298 * configure.in: Use AC_FUNC_STRNLEN.
7299 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
7301 2002-01-09 Akim Demaille <akim@epita.fr>
7303 * src/files.c, src/files.h (output_infix): New.
7304 (tab_extension): Remove.
7305 (compute_base_names): Compute the former, drop the latter.
7306 * src/output.c (prepare): Insert the muscles `output-infix', and
7308 * src/parse-skel.y (string, string.1): New.
7309 (section.header): Use it.
7310 (section.yacc): Remove.
7311 (prefix): Remove too.
7312 * src/scan-skel.l: Adjust.
7313 * src/bison.simple, src/bison.hairy: Adjust.
7315 2002-01-09 Akim Demaille <akim@epita.fr>
7317 * configure.in (WERROR_CFLAGS): Compute it.
7318 * src/Makefile.am (CFLAGS): Pass it.
7319 * tests/atlocal.in (CFLAGS): Idem.
7320 * src/files.c: Fix a few warnings.
7321 (get_extension_index): Remove, unused.
7323 2002-01-08 Akim Demaille <akim@epita.fr>
7325 * src/getargs.c (AS_FILE_NAME): New.
7326 (getargs): Use it to convert DOSish file names.
7327 * src/files.c (base_name): Rename as full_base_name to avoid
7328 clashes with `base_name ()'.
7329 (filename_split): New.
7330 (compute_base_names): N-th rewrite, using filename_split.
7332 2002-01-08 Akim Demaille <akim@epita.fr>
7334 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
7335 New, stolen from the Fileutils 4.1.
7336 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
7337 * configure.in: Check for the presence of memrchr, and of its
7340 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
7342 * lib/hash.h (__P): Added definition for this macro.
7343 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
7344 BUILT_SOURCES, to ensure they are generated first.
7345 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
7346 %error-verbose to allow bootstrapping with bison 1.30x.
7348 2002-01-06 Akim Demaille <akim@epita.fr>
7350 * src/reader.c (parse_braces): Don't fetch the next char, the
7351 convention is to fetch on entry.
7352 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
7353 'switch' without a following semicolon.
7354 * tests/regression.at (braces parsing): New.
7356 2002-01-06 Akim Demaille <akim@epita.fr>
7358 Bison is dead wrong in its RR conflict reports.
7360 * tests/torture.at (GNU Cim Grammar): New.
7361 * src/conflicts.c (count_rr_conflicts): Fix.
7363 2002-01-06 Akim Demaille <akim@epita.fr>
7365 Creating package.m4 from configure.ac causes too many problems.
7367 * tests/Makefile.am (package.m4): Create it by hand,
7368 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
7370 2002-01-06 Akim Demaille <akim@epita.fr>
7372 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
7375 2002-01-04 Paul Eggert <eggert@twinsun.com>
7377 * doc/bison.texinfo (Debugging):
7378 Remove YYSTDERR; it's no longer defined or used.
7379 Also, s/cstdio.h/cstdio/.
7381 2002-01-03 Akim Demaille <akim@epita.fr>
7383 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
7385 2002-01-03 Akim Demaille <akim@epita.fr>
7387 * src/parse-skel.y (process_skeleton): Don't bind the parser's
7388 tracing code to --trace, wait for a better --trace option, with
7391 2002-01-03 Akim Demaille <akim@epita.fr>
7393 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
7394 The ISO C++ standard is extremely clear about it: stderr is
7395 considered a macro, not a regular symbol (see table 94 `Header
7396 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
7397 Therefore std:: does not apply to it. It still does with fprintf.
7398 Also, s/cstdio.h/cstdio/.
7400 2002-01-03 Akim Demaille <akim@epita.fr>
7402 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
7403 for non system headers.
7405 2002-01-02 Akim Demaille <akim@epita.fr>
7407 Equip the skeleton chain with location tracking, runtime trace,
7408 pure parser and scanner.
7410 * src/parse-skel.y: Request a pure parser, locations, and prefix
7412 (%union): Having several members with the same type does not help
7413 type mismatches, simplify.
7414 (YYPRINT, yyprint): New.
7415 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
7418 * src/scan-skel.l: Adjust to these changes.
7419 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
7420 (LOCATION_PRINT, skel_control_t): New.
7422 2001-12-30 Akim Demaille <akim@epita.fr>
7424 * src/parse-skel.y: Get rid of the shift/reduce conflict:
7425 replace `gb' with BLANKS.
7426 * src/scan-skel.l: Adjust.
7428 2001-12-30 Akim Demaille <akim@epita.fr>
7430 * src/system.h: We don't need nor want bcopy.
7431 Throw away MS-DOS crap: we don't need getpid.
7432 * configure.in: We don't need strndup. It was even causing
7433 problems: because Flex includes the headers *before* us,
7434 _GNU_SOURCE is not defined by config.h, and therefore strndup was
7436 * lib/xstrndup.c: New.
7437 * src/scan-skel.l: Use it.
7438 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
7439 * src/parse-skel.y: Use %directives instead of #defines.
7441 2001-12-30 Akim Demaille <akim@epita.fr>
7443 * src/skeleton.h: New.
7444 * src/output.c (output_parser, output_master_parser): Remove, dead
7446 * src/output.h (get_lines_number, actions_output, guards_output)
7447 (token_definitions_output): Prototype them.
7448 * src/parse-skel.y: Add the license notice.
7449 Include output.h and skeleton.h.
7450 (process_skeleton): Returns void, and takes a single parameter.
7451 * src/scan-skel.l: Add the license notice.
7453 Don't use %option yylineno: it seems that then Flex imagines
7454 REJECT has been used, and therefore it won't reallocate its
7455 buffers (which makes no other sense to me than a bug). It results
7456 in warnings for `unused: yy_flex_realloc'.
7458 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
7460 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
7461 (MUSCLE_INSERT_PREFIX): ...to there.
7462 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
7463 (MUSCLE_INSERT_PREFIX): Move from here...
7465 * src/bison.hairy: Add a section directive. Put braces around muscle
7466 names. This parser skeleton is still broken, but Bison should not
7467 choke on a bad muscle 'syntax'.
7468 * src/bison.simple: Add a section directive. Put braces around muscle
7471 * src/files.h (strsuffix, stringappend): Add declarations.
7472 (tab_extension): Add declaration.
7473 (short_base_name): Add declaration.
7475 * src/files.c (strsuffix, stringappend): No longer static. These
7476 functions are used in the skeleton parser.
7477 (tab_extension): New.
7478 (compute_base_names): Use the computations done in this function
7479 to guess if the generated parsers should have '.tab' in their
7481 (short_base_name): No longer static.
7483 * src/output.c (output_skeleton): New.
7484 (output): Disable call to output_master_parser, and give a try to
7485 a new skeleton handling system.
7486 (guards_output, actions_output): No longer static.
7487 (token_definitions_output, get_lines_number): No longer static.
7489 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
7491 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
7494 * src/parse-skel.y: New file.
7495 * src/scan-skel.l: New file.
7497 2001-12-29 Akim Demaille <akim@epita.fr>
7499 %name-prefix is broken.
7501 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
7502 Adjust all dependencies.
7503 * tests/headers.at (export YYLTYPE): Strengthen this test: use
7506 Renaming yylval but not yylloc is not consistent. Now we do.
7508 * src/bison.simple: Prefix yylloc if used.
7509 * doc/bison.texinfo (Decl Summary): Document that.
7511 2001-12-29 Akim Demaille <akim@epita.fr>
7513 * doc/bison.texinfo: Promote `%long-directive' over
7515 Remove all references to fixed-output-files, yacc is enough.
7517 2001-12-29 Akim Demaille <akim@epita.fr>
7519 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
7520 user prologue. These are defaults.
7521 * tests/actions.at (Mid-rule actions): Make sure the user can
7522 define YYDEBUG and YYERROR_VERBOSE.
7524 2001-12-29 Akim Demaille <akim@epita.fr>
7526 * src/output.c (header_output): Don't forget to export YYLTYPE and
7528 * tests/headers.at (export YYLTYPE): New, make sure it does.
7529 * tests/regression.at (%union and --defines, Invalid CPP headers):
7531 * tests/headers.at: here.
7533 2001-12-29 Akim Demaille <akim@epita.fr>
7535 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
7537 2001-12-29 Akim Demaille <akim@epita.fr>
7539 * tests/actions.at (Mid-rule actions): Output on a single line
7542 2001-12-29 Akim Demaille <akim@epita.fr>
7544 * doc/bison.texinfo: Formatting changes.
7546 2001-12-29 Akim Demaille <akim@epita.fr>
7548 Don't store the token defs in a muscle, just be ready to output it
7549 on command. Now possible via `symbols'. Fixes a memory leak.
7551 * src/output.c (token_definitions_output): New.
7552 (output_parser, header_output): Use it.
7553 * src/reader.c (symbols_save): Remove.
7555 2001-12-29 Akim Demaille <akim@epita.fr>
7557 * src/bison.simple: Do not provide a default for YYSTYPE and
7558 YYLTYPE before the user's prologue. Otherwise it's hardly... a
7561 2001-12-29 Akim Demaille <akim@epita.fr>
7563 Mid-rule actions are simply... ignored!
7565 * src/reader.c (readgram): Be sure to attach mid-rule actions to
7566 the empty-rule associated to the dummy symbol, not to the host
7568 * tests/actions.at (Mid-rule actions): New.
7570 2001-12-29 Akim Demaille <akim@epita.fr>
7574 * src/reader.c (reader): Free grammar.
7576 2001-12-29 Akim Demaille <akim@epita.fr>
7580 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
7581 since it allocates it for each state, although only one is needed.
7582 (allocate_storage): Do it here.
7584 2001-12-29 Akim Demaille <akim@epita.fr>
7586 * src/options.h, src/options.c (create_long_option_table): Rename
7588 (long_option_table_new): this, with a clearer prototype.
7589 (percent_table): Remove, unused,
7590 * src/getargs.c (getargs): Adjust.
7592 2001-12-29 Akim Demaille <akim@epita.fr>
7594 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
7595 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
7598 2001-12-29 Akim Demaille <akim@epita.fr>
7600 * src/lalr.c (build_relations): Rename `states' as `states1'.
7601 Sorry, I don't understand exactly what it is, no better name...
7603 2001-12-29 Akim Demaille <akim@epita.fr>
7605 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
7606 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
7607 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
7610 2001-12-29 Akim Demaille <akim@epita.fr>
7612 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
7615 2001-12-29 Akim Demaille <akim@epita.fr>
7617 * src/reader.c, src/reader.h (user_toknums): Remove.
7618 Adjust all users to use symbols[i]->user_token_number.
7620 2001-12-29 Akim Demaille <akim@epita.fr>
7622 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
7623 Adjust all users to use symbols[i]->prec or ->assoc.
7625 2001-12-29 Akim Demaille <akim@epita.fr>
7627 * src/reader.c, src/reader.h (tags): Remove.
7628 Adjust all users to use symbols[i]->tag.
7630 2001-12-29 Akim Demaille <akim@epita.fr>
7632 * src/gram.h, src/gram.c (symbols): New, similar to state_table
7634 * src/reader.c (packsymbols): Fill this table.
7636 * src/conflicts.c (resolve_sr_conflict): Adjust.
7637 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
7639 Use symbols[i]->tag instead of tags[i].
7641 2001-12-29 Akim Demaille <akim@epita.fr>
7643 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
7644 In addition, put a comment in there, to replace...
7645 * tests/regression.at (%union and C comments): Remove.
7647 2001-12-29 Akim Demaille <akim@epita.fr>
7649 * tests/regression.at (Web2c Actions): Blindly move the actual
7650 output as expected output. The contents *seem* right to me, but I
7651 can't pretend reading perfectly parser tables... Nonetheless, all
7652 the other tests pass correctly, the table look OK, even though the
7653 presence of `$axiom' is to be noted: AFAICS it is useless (but
7656 2001-12-29 Akim Demaille <akim@epita.fr>
7658 * src/reader.c (readgram): Don't add the rule 0 if there were no
7659 rules read. In other words, add it _after_ having performed
7660 grammar sanity checks.
7661 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
7663 2001-12-29 Akim Demaille <akim@epita.fr>
7665 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
7666 visible, and some states have now a different number.
7668 2001-12-29 Akim Demaille <akim@epita.fr>
7670 * src/reader.c (readgram): Bind the initial rule's lineno to that
7672 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
7673 (Solved SR Conflicts): Adjust rule 0's line number.
7675 2001-12-29 Akim Demaille <akim@epita.fr>
7677 Fix the `GAWK Grammar' failure.
7679 * src/LR0.c (final_state): Initialize to -1 so that we do compute
7680 the reductions of the first state which was mistakenly confused
7681 with the final state because precisely final_state was initialized
7683 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
7684 now noticed by Bison.
7685 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
7686 have a reduction on $default.
7688 2001-12-29 Akim Demaille <akim@epita.fr>
7690 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
7692 * src/closure.c (print_closure): Likewise.
7693 * src/derives.c (print_derives): Likewise.
7694 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
7697 2001-12-29 Akim Demaille <akim@epita.fr>
7699 * src/lalr.c (lookaheads_print): New.
7700 (lalr): Call it when --trace-flag.
7701 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
7704 2001-12-29 Akim Demaille <akim@epita.fr>
7706 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
7707 when walking through ritem, even via rule->rhs.
7708 * src/reduce.c (dump_grammar, useful_production, reduce_output)
7709 (useful_production, useless_nonterminals): Likewise.
7710 (reduce_grammar_tables): Likewise, plus update nritems.
7711 * src/nullable.c (set_nullable): Likewise.
7712 * src/lalr.c (build_relations): Likewise.
7713 * tests/sets.at (Nullable): Adjust.
7714 Fortunately, now, the $axiom is no longer nullable.
7716 2001-12-29 Akim Demaille <akim@epita.fr>
7718 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
7720 * src/gram.c (ritem_longest_rhs): Likewise.
7721 * src/reduce.c (nonterminals_reduce): Likewise.
7722 * src/print_graph.c (print_graph): Likewise.
7723 * src/output.c (output_rule_data): Likewise.
7724 * src/nullable.c (set_nullable): Likewise.
7726 2001-12-29 Akim Demaille <akim@epita.fr>
7728 * src/output.c: Comment changes.
7730 2001-12-27 Paul Eggert <eggert@twinsun.com>
7732 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
7733 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
7734 Sparc, as they were causing more porting problems than the
7735 (minor) performance improvement was worth.
7737 Also, catch up with 1.31's YYSTD.
7739 2001-12-27 Akim Demaille <akim@epita.fr>
7741 * src/output.c (output_gram): Rely on nritems, not the
7742 0-sentinel. See below.
7743 Use -1 as separator, not 0.
7744 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
7745 Rely on -1 as separator in yyrhs, instead of 0.
7746 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
7747 twice `Now at end of input', therefore there are two lines less to
7750 2001-12-27 Akim Demaille <akim@epita.fr>
7752 * tests/regression.at (Unresolved SR Conflicts):
7753 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
7756 2001-12-27 Akim Demaille <akim@epita.fr>
7758 * src/LR0.c (new_state): Recognize the final state by the fact it
7759 is reached by eoftoken.
7760 (insert_start_shifting_state, insert_eof_shifting_state)
7761 (insert_accepting_state, augment_automaton): Remove, since now
7762 these states are automatically computed from the initial state.
7763 (generate_states): Adjust.
7764 * src/print.c: When reporting a rule number to the user, substract
7765 1, so that the axiom rule is rule 0, and the first user rule is 1.
7766 * src/reduce.c: Likewise.
7767 * src/print_graph.c (print_core): For the time being, just as for
7768 the report, depend upon --trace-flags to dump the full set of
7770 * src/reader.c (readgram): Once the grammar read, insert the rule
7771 0: `$axiom: START-SYMBOL $'.
7772 * tests/set.at: Adjust: rule 0 is now displayed, and since the
7773 number of the states has changed (the final state is no longer
7774 necessarily the last), catch up.
7776 2001-12-27 Akim Demaille <akim@epita.fr>
7778 Try to make the use of the eoftoken valid. Given that its value
7779 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
7780 is used instead of > 0 where appropriate, (ii), depend upon nritems
7781 instead of the 0-sentinel.
7783 * src/gram.h, src/gram.c (nritems): New.
7784 Expected to be duplication of nitems, but for the time being...
7785 * src/reader.c (packgram): Assert nritems and nitems are equal.
7786 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
7787 * src/closure.c (print_closure, print_fderives): Likewise.
7788 * src/gram.c (ritem_print): Likewise.
7789 * src/print.c (print_core, print_grammar): Likewise.
7790 * src/print_graph.c: Likewise.
7792 2001-12-27 Akim Demaille <akim@epita.fr>
7794 * src/main.c (main): If there are complains after grammar
7795 reductions, then output the report anyway if requested, then die.
7796 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
7797 * src/reader.c (eoftoken): New.
7798 (parse_token_decl): If the token being defined has value `0', it
7800 (packsymbols): No longer hack `tags' to insert `$' by hand.
7801 Be sure to preserve the value of the eoftoken.
7802 (reader): Make sure eoftoken is defined.
7803 Initialize nsyms to 0: now eoftoken is created just like the others.
7804 * src/print.c (print_grammar): Don't special case the eof token.
7805 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
7806 lie anyway, albeit pleasant.
7807 * tests/calc.at: Exercise error messages with eoftoken.
7808 Change the grammar so that empty input is invalid.
7809 Adjust expectations.
7810 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
7812 2001-12-27 Akim Demaille <akim@epita.fr>
7814 * configure.in: Check the protos of strchr ans strspn.
7815 Replace strchr if needed.
7816 * src/system.h: Provide the protos of strchr, strspn and memchr if
7818 * lib/strchr.c: New.
7819 * src/reader.c (symbols_save): Use strchr.
7821 2001-12-27 Akim Demaille <akim@epita.fr>
7823 * src/print.c, src/print_graph.c (escape): New.
7824 Use it to quote the TAGS outputs.
7825 * src/print_graph.c (print_state): Now errors are in red, and
7826 reductions in green.
7827 Prefer high to wide: output the state number on a line of its own.
7829 2001-12-27 Akim Demaille <akim@epita.fr>
7831 * src/state.h, src/state.c (reductions_new): New.
7832 * src/LR0.c (set_state_table): Let all the states have a
7833 `reductions', even if reduced to 0.

7836 * src/print.c (print_reductions, print_actions): Adjust.

7852 2001-12-27 Akim Demaille <akim@epita.fr>
7854 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
7855 * src/print.c: here.
7856 (lookaheadset, shiftset): New, used as additional storage by
7858 (print_results): Adjust.
7859 (print_shifts, print_gotos, print_errs): New, extracted from...
7860 (print_actions): here.
7861 * src/print_graph.c (print_actions): Remove dead code.
7863 2001-12-27 Akim Demaille <akim@epita.fr>
7865 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
7868 2001-12-27 Akim Demaille <akim@epita.fr>
7870 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

7884 * src/files.c, src/files.h (guard_obstack): Remove.
7885 * src/output.c (output): Adjust.
7886 * src/reader.c (parse_braces): New, factoring...
7887 (copy_action, copy_guard): these two which are renamed as...
7888 (parse_action, parse_guard): these.
7889 As a voluntary consequence, using braces around guards is now
7892 2001-12-27 Akim Demaille <akim@epita.fr>
7894 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
7895 * src/reader.c (symbol_list): `guard' and `guard_line' are new
7897 (symbol_list_new): Adjust.
7898 (copy_action): action_line is the first line, not the last.
7899 (copy_guard): Just as for actions, store the `action' only, not
7900 the switch/case/break flesh.
7901 Don't parse the user action that might follow the guard, let...
7902 (readgram): do it, i.e., now, there can be an action after a
7904 In other words the guard is just explicitly optional.
7906 * src/output.c (guards_output): New.
7907 (output_parser): Call it when needed.
7908 (output): Also free the guard and attrs obstacks.
7909 * src/files.c, src/files.h (obstack_save): Remove.
7910 (output_files): Remove.
7911 As a result, if one needs the former `.act' file, using an
7912 appropriate skeleton which requires actions and guards is now
7914 * src/main.c (main): Adjust.
7915 * tests/semantic.at: New.
7916 * tests/regression.at: Use `input.y' as input file name.
7917 Avoid 8+3 problems by requiring input.c when the test needs the

7922 * src/reader.c (symbol_list_new): Be sure to initialize all the
7925 2001-12-27 Akim Demaille <akim@epita.fr>
7927 All the hacks using a final pseudo state are now useless.

7930 * src/lalr.c (nLA): New.
7931 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
7932 instead of lookaheadsp from the pseudo state (nstate + 1).
7934 2001-12-27 Akim Demaille <akim@epita.fr>
7936 * src/output.c (action_row, token_actions): Use a state_t instead
7937 of a integer, and nlookaheads instead of the following state's

7942 * src/conflicts.c (log_resolution, flush_shift)
7943 (resolve_sr_conflict, set_conflicts, solve_conflicts)
7944 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
7945 (conflicts_print, print_reductions): Use a state_t instead of an
7946 integer when referring to a state.
7947 As much as possible, depend upon nlookaheads, instead of the
7948 `lookaheadsp' member of the following state (since lookaheads of
7949 successive states are successive, the difference between state n + 1
7950 and n served as the number of lookaheads for state n).
7951 * src/lalr.c (add_lookback_edge): Likewise.
7952 * src/print.c (print_core, print_actions, print_state)
7953 (print_results): Likewise.

7967 * src/output.c (prepare): Drop the muscle `ntbase' which
7969 * src/bison.simple: Formatting/comment changes.
7970 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
7971 is an undocumented synonym.
7973 2001-12-22 Akim Demaille <akim@epita.fr>
7975 * src/output.c (output_table_data): Change the prototype to use
7976 `int' for array ranges: some invocations do pass an int, not a
7978 Reported by Wayne Green.
7980 2001-12-22 Akim Demaille <akim@epita.fr>
7982 Some actions of web2c.y are improperly triggered.
7983 Reported by Mike Castle.
7985 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

7987 (Web2c Report): this.
7988 (Web2c Actions): New.
7990 2001-12-22 Akim Demaille <akim@epita.fr>

7998 2001-12-18 Akim Demaille <akim@epita.fr>
8000 Some host fail on `assert (!"foo")', which expands to
8001 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
8002 Reported by Nelson Beebee.
8004 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
8005 `#define it_succeeded 0' and `assert (it_succeeded)'.
8007 2001-12-17 Marc Autret <autret_m@epita.fr>
8009 * src/bison.simple: Don't hard code the skeleton line and filename.
8010 * src/output.c (output_parser): Rename 'line' as 'output_line'.
8011 New line counter 'skeleton_line' (skeleton-line muscle).
8013 2001-12-17 Paul Eggert <eggert@twinsun.com>
8015 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
8016 YYDEBUG must be defined to a nonzero value.
8018 * src/bison.simple (yytname): Do not assume that the user defines
8019 YYDEBUG to a properly parenthesized expression.
8021 2001-12-17 Akim Demaille <akim@epita.fr>
8023 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

8026 * src/lalr.h (nlookaheads): Remove this orphan declaration.
8027 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
8030 2001-12-17 Akim Demaille <akim@epita.fr>

8033 * src/main.c (main): Don't open/close files, nor invoke lex_free,
8035 * src/reader.c (reader): Do it.
8037 2001-12-17 Akim Demaille <akim@epita.fr>
8039 * src/conflicts.c (print_reductions): Formatting changes.
8041 2001-12-17 Akim Demaille <akim@epita.fr>
8043 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
8044 (flush_reduce): New.
8045 (resolve_sr_conflict): Adjust.
8047 2001-12-17 Akim Demaille <akim@epita.fr>
8049 * src/output.c (output_obstack): Be static and rename as...
8050 (format_obstack): this, to avoid any confusion with files.c's
8052 * src/reader.h (muscle_obstack): Move to...
8053 * src/output.h: here, since it's defined in output.c.
8055 2001-12-17 Akim Demaille <akim@epita.fr>
8057 * src/output.c (action_row, save_column, default_goto)
8058 (sort_actions, matching_state, pack_vector): Better variable
8061 2001-12-17 Akim Demaille <akim@epita.fr>
8063 * src/output.c: Various formatting changes.
8065 2001-12-17 Akim Demaille <akim@epita.fr>

8073 2001-12-16 Marc Autret <autret_m@epita.fr>
8075 * src/output.c (actions_output): Fix. When we use %no-lines,
8076 there is one less line per action.
8078 2001-12-16 Marc Autret <autret_m@epita.fr>
8080 * src/bison.simple: Remove a useless #line directive.
8081 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
8082 * src/output.c (get_lines_number): New.
8083 (output_parser): Adjust, now takes care about the lines of a
8086 (actions_output): Computes the number of lines taken by actions.
8087 (output_master_parser): Insert new skeleton which is the name of
8088 the output parser file name.

8098 2001-12-15 Akim Demaille <akim@epita.fr>
8100 Make `make distcheck' work.
8102 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
8103 system.h which uses libgettext.h.
8105 2001-12-15 Akim Demaille <akim@epita.fr>
8107 * src/nullable.c (set_nullable): Useless rules must be skipped,
8108 otherwise, since we range over their symbols, we might look at a
8109 nonterminal which no longer ``exists'', i.e., it is not counted in
8110 `nvars', hence we overflow our arrays.
8112 2001-12-15 Akim Demaille <akim@epita.fr>
8114 The header can also be produced directly, without any obstack!
8117 * src/files.c, src/files.h (defines_obstack): Remove.
8118 (compute_header_macro): Global.
8119 (defines_obstack_save): Remove.
8120 * src/reader.c (parse_union_decl): No longer output to
8121 defines_obstack: its content can be found in the `stype' muscle

8124 (symbols_output): this.
8126 (symbols_save): this.
8128 * src/output.c (header_output): New.
8131 2001-12-15 Akim Demaille <akim@epita.fr>
8133 * src/reader.c (parse_union_decl): Instead of handling two obstack
8134 simultaneously, use one to define the `stype' muscle, and use the
8135 value of the latter to fill defines_obstack.
8136 (copy_comment): Remove.
8137 (copy_comment2): Work for a single obstack.
8139 (copy_comment): this.
8141 2001-12-15 Akim Demaille <akim@epita.fr>
8143 * src/lex.c, src/lex.h (xgetc): No longer static.
8144 * src/reader.c (parse_union_decl): Revamp.
8146 2001-12-15 Akim Demaille <akim@epita.fr>
8148 Still making progress in separating Bison into (i) input, (ii)
8149 process, (iii) output: now we can directly output the parser file
8150 without using table_obstack at all.
8152 * src/files.c, src/files.h (table_obstack): Bye bye.
8153 (parser_file_name): New.
8154 * src/files.c (compute_output_file_names): Compute it.
8155 * src/output.c (actions_output, output_parser)
8156 (output_master_parser): To a file instead of an obstack.
8158 2001-12-15 Akim Demaille <akim@epita.fr>
8160 Attach actions to rules, instead of pre-outputting them to
8163 * src/gram.h (rule_t): action and action_line are new members.
8164 * src/reader.c (symbol_list): Likewise.
8165 (copy_action): Save the actions within the rule.
8166 (packgram): Save them in rule_table.
8167 * src/output.c (actions_output): New.
8168 (output_parser): Use it on `%%actions'.
8169 (output_rule_data): Don't free rule_table.
8171 (prepare): Don't save the `action' muscle.
8172 * src/bison.simple: s/%%action/%%actions/.
8174 2001-12-15 Akim Demaille <akim@epita.fr>
8176 * src/reader.c (copy_action): When --yacc, don't append a `;'
8177 to the user action: let it fail if lacking.
8178 Suggested by Arnold Robbins and Tom Tromey.
8180 2001-12-14 Akim Demaille <akim@epita.fr>
8182 * src/lex.c (literalchar): Simply return the char you decoded, non
8183 longer mess around with obstacks and int pointers.
8186 2001-12-14 Akim Demaille <akim@epita.fr>
8188 * src/lex.c (literalchar): Don't escape the special characters,
8189 just decode them, and keep them as char (before, eol was output as
8190 the 2 char string `\n' etc.).
8191 * src/output.c (output_rule_data): Use quotearg to output the
8194 2001-12-13 Paul Eggert <eggert@twinsun.com>
8196 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
8197 Do not infringe on the global user namespace when using C++.
8198 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
8199 All uses of `fprintf' and `stderr' changed.
8201 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
8203 2001-12-13 Akim Demaille <akim@epita.fr>
8205 The computation of nullable is broken: it doesn't handle empty
8208 * tests/torture.at (GNU AWK Grammar): New.
8209 * tests/sets.at (Nullable): New.
8210 * src/nullable.c (set_nullable): Instead of blindly looping over
8211 `ritems', loop over the rules, and then over their rhs's.
8213 Work around Autotest bugs.
8215 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
8216 frame, because Autotest understand lines starting with a `+' as
8217 traces from the shell. Then, they are not processed properly.
8218 Admittedly an Autotest bug, but we don't have time to wait for
8219 Autotest to catch up.
8220 * tests/regression.at (Broken Closure): Adjust to the new table
8223 * tests/sets.at: here.
8225 2001-12-13 Akim Demaille <akim@epita.fr>
8227 * src/closure.c (closure): Use nrules instead of playing tricks
8230 2001-12-13 Akim Demaille <akim@epita.fr>
8232 * src/print.c (print_actions): Output the handling of `$' as the
8233 traces do: shifting the token EOF. Before EOF was treated as a
8235 * tests/regression.at: Adjust some tests.
8236 * src/print_graph.c (print_core): Complete the set of items via
8237 closure. The next-to-final and final states are still unsatisfying,
8238 but that's to be addressed elsewhere.
8239 No longer output the rule numbers, but do output the state number.
8240 A single loop for the shifts + gotos is enough, but picked a
8241 distinct color for each.
8242 (print_graph): Initialize and finalize closure.
8244 2001-12-13 Akim Demaille <akim@epita.fr>
8246 * src/reader.c (readgram): Remove dead code, an strip useless
8248 (get_type): Remove, unused.
8250 2001-12-12 Akim Demaille <akim@epita.fr>
8252 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
8253 on that of lib/error.c.
8255 2001-12-12 Akim Demaille <akim@epita.fr>
8257 Some hosts don't like `/' in includes.
8259 * src/system.h: Include libgettext.h without qualifying the path.

8265 * src/output.c (output_parser): Remove useless muscle.
8267 2001-12-11 Marc Autret <autret_m@epita.fr>
8269 * src/bison.simple: Remove #line just before %%epilogue. It
8270 is now handled in ...
8271 * src/reader.c (read_additionnal_code): Add the output of a
8272 #line for the epilogue.
8274 2001-12-10 Marc Autret <autret_m@epita.fr>
8276 * src/reader.c (copy_definition): Re-use CPP-outed code which
8277 replace precedent remove.
8278 * src/bison.simple: Remove #line before %%prologue because
8279 %%input-line is wrong at this time.
8281 2001-12-10 Marc Autret <autret_m@epita.fr>
8283 * src/reader.c (symbols_output): Clean up.
8284 * src/output.c (output_gram, output): Clean up.
8286 2001-12-10 Akim Demaille <akim@epita.fr>
8288 * src/lalr.c (initialize_lookaheads): New. Extracted from...
8289 * src/LR0.c (set_state_table): here.
8290 * src/lalr.c (lalr): Call it.
8292 2001-12-10 Akim Demaille <akim@epita.fr>
8294 * src/state.h (shifts): Remove the `number' member: shifts are
8295 attached to state, hence no longer need to be labelled with a
8298 2001-12-10 Akim Demaille <akim@epita.fr>
8300 Now that states have a complete set of members, the linked list of
8301 shifts is useless: just fill directly the state's shifts member.
8303 * src/state.h (shifts): Remove the `next' member.
8304 * src/LR0.c (first_state, last_state): Remove.
8306 (augment_automaton): Don't look for the shifts that must be added
8307 a shift on EOF: it is those of the state we looked for! But now,
8308 since shifts are attached, it is no longer needed to looking
8309 merely by its id: its number.
8311 2001-12-10 Akim Demaille <akim@epita.fr>
8313 * src/LR0.c (augment_automaton): Better variable locality.
8314 Remove an impossible branch: if there is a state corresponding to
8315 the start symbol being shifted, then there is shift for the start
8316 symbol from the initial state.
8318 2001-12-10 Akim Demaille <akim@epita.fr>
8320 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
8321 only when appropriate: when insert_start_shifting_state' is not
8323 * tests/regression.at (Rule Line Numbers): Adjust.
8325 2001-12-10 Akim Demaille <akim@epita.fr>
8327 * src/LR0.c (augment_automaton): Now that all states have shifts,
8328 merge the two cases addition shifts to the initial state.
8330 2001-12-10 Akim Demaille <akim@epita.fr>
8332 * src/lalr.c (set_state_table): Move to...
8334 * src/lalr.c (lalr): Don't call it...
8335 * src/LR0.c (generate_states): do it.
8336 * src/LR0.h (first_state): Remove, only the table is used.
8338 2001-12-10 Akim Demaille <akim@epita.fr>
8340 * src/LR0.h (first_shift, first_reduction): Remove.
8341 * src/lalr.c: Don't use first_shift: find shifts through the
8344 2001-12-10 Akim Demaille <akim@epita.fr>
8346 * src/LR0.c: Attach shifts to states as soon as they are
8348 * src/lalr.c (set_state_table): Instead of assigning shifts to
8349 state, just assert that the mapping was properly done.
8351 2001-12-10 Akim Demaille <akim@epita.fr>
8353 * src/LR0.c (insert_start_shift): Rename as...
8354 (insert_start_shifting_state): this.
8355 (insert_eof_shifting_state, insert_accepting_state): New.
8356 (augment_automaton): Adjust.
8357 Better locality of the variables.
8358 When looking if the start_symbol is shifted from the initial
8359 state, using `while (... symbol != start_symbol ...)' sounds
8360 better than `while (... symbol < start_symbol ...)': If fail
8361 to see how the order between symbols could be relevant!
8363 2001-12-10 Akim Demaille <akim@epita.fr>
8365 * src/getargs.h: Don't declare `spec_name_prefix' and
8366 `spec_file_prefix', declared by src/files.h.
8367 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
8368 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
8369 * src/output.c (prepare): Adjust.
8370 * src/reader.c (symbols_output): Likewise.
8371 * src/vmsgetargs.c: Vaguely adjust, but who cares?
8373 2001-12-10 Akim Demaille <akim@epita.fr>
8375 * src/muscle_tab.c (muscle_init): NULL is a better default than
8378 2001-12-10 Akim Demaille <akim@epita.fr>
8380 * src/reader.c (reader): Calling symbols_output once is enough.
8382 2001-12-10 Akim Demaille <akim@epita.fr>
8384 Now that states have a complete set of members, the linked list of
8385 reductions is useless: just fill directly the state's reductions
8388 * src/state.h (struct reductions): Remove member `number' and
8390 * src/LR0.c (first_reduction, last_reduction): Remove.
8391 (save_reductions): Don't link the new reductions, store them in
8393 * src/lalr.c (set_state_table): No need to attach reductions to
8394 states, it's already done.
8395 * src/output.c (output_actions): No longer free the shifts, then
8396 the reductions, then the states: free all the states and their
8399 2001-12-10 Akim Demaille <akim@epita.fr>
8401 * src/options.c (OPTN, DRTV, BOTH): New.
8402 (option_table): Use them.
8404 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
8405 the job of system.h.
8406 * src/options.c: Don't include stdio.h and xalloc.h for the same
8409 2001-12-10 Akim Demaille <akim@epita.fr>
8411 * src/output.c (output, prepare): Make sure the values of the
8412 muscles `action' and `prologue' are 0-terminated.
8414 2001-12-10 Akim Demaille <akim@epita.fr>
8416 Clean up GCC warnings.
8418 * src/reader.c (copy_action): `buf' is not used.
8419 (parse_skel_decl): Be static.
8420 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
8421 * src/options.h (create_long_option_table): Have a real prototype.
8422 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
8423 (hash_delete_at): Return const void *.
8424 Adjust casts to preserve the const.
8426 2001-12-10 Akim Demaille <akim@epita.fr>
8428 * configure.in: Require 2.52g.
8429 M4 is not needed, but AUTOM4TE is.
8431 * tests/Makefile.am: Adjust.
8433 2001-12-10 Akim Demaille <akim@epita.fr>
8435 One structure for states is enough, even though theoretically
8436 there are LR(0) states and LALR(1) states.
8438 * src/lalr.h (state_t): Remove.
8439 (state_table): Be state_t **, not state_t *.
8440 * src/state.h (core, CORE_ALLOC): Rename as...
8441 (state_t, STATE_ALLOC): this.
8442 Add the LALR(1) members: shifts, reductions, errs.
8443 * src/LR0.c (state_table): Rename as...
8444 (state_hash): this, to avoid name clashes with the global
8446 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
8447 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
8449 2001-12-10 Akim Demaille <akim@epita.fr>
8451 Bison dumps core on bash.y.
8452 Reported by Pascal Bart.
8454 * src/warshall.c (bitmatrix_print): New.
8456 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
8457 j must be the outer loop.
8458 * tests/regression.at (Broken Closure): New.
8460 2001-12-05 Akim Demaille <akim@epita.fr>
8462 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
8464 Reported by Peter Hamorsky.

8468 * src/conflicts.c (err_table): Remove.
8469 (resolve_sr_conflict): Adjust.
8470 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
8472 (state_t.reductions, state_t.shifts): this.
8474 2001-12-05 Akim Demaille <akim@epita.fr>
8476 * src/reduce.c (reduce_grammar_tables): No longer disable the
8477 removal of useless rules via CPP but via `if (0)', so that the
8478 compiler still check the code is valid.
8479 For instance, it should have noticed `rline' no longer exists: use
8480 the `line' member of rule_t.
8481 * src/gram.c (dummy, rline): Remove, unused.
8483 2001-12-05 Akim Demaille <akim@epita.fr>
8485 * src/output.c (pack_vector): Use assert, not berror.
8486 * src/main.c (berror): Remove, unused.
8488 2001-12-05 Akim Demaille <akim@epita.fr>
8490 New experimental feature: if --verbose --trace output all the
8491 items of a state, not only its kernel.
8493 * src/print.c (print_core): If `trace_flag', then invoke closure
8494 before outputting the items of the state (print_core is no longer
8495 a correct name them).
8496 (print_results): Invoke new_closure/free_closure if needed.
8498 2001-12-05 Akim Demaille <akim@epita.fr>
8500 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
8501 * src/closure.c, src/closure.h (itemsetsize): Rename as...
8502 (nitemset): for consistency with the rest of the project.
8504 2001-12-05 Akim Demaille <akim@epita.fr>
8506 * src/closure.c (print_closure): Improve.
8507 (closure): Use it for printing input and output.
8509 2001-12-05 Akim Demaille <akim@epita.fr>
8511 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
8512 indexed by nonterminals.
8514 2001-12-05 Akim Demaille <akim@epita.fr>
8516 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

8534 * src/output.c (action_row): De-obfuscate
8535 using the good o' techniques: arrays not pointers, variable
8536 locality, BITISSET, RESETBIT etc.
8538 2001-12-05 Akim Demaille <akim@epita.fr>
8540 Pessimize the code to simplify it: from now on, all the states
8541 have a valid SHIFTS, which NSHIFTS is possibly 0.
8543 * src/LR0.c (shifts_new): Be global and move to..
8544 * src/state.c, src/state.h: here.
8545 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

8550 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
8551 * src/conflicts.c: Use it.
8552 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
8553 incorrectly ``simplified''.
8555 2001-12-05 Akim Demaille <akim@epita.fr>
8557 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
8558 using the good o' techniques: arrays not pointers, variable

8563 * src/state.h (SHIFT_SYMBOL): New.

8568 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
8569 (print_reductions): De-obfuscate using the good o' techniques:

8613 * src/lalr.c (build_relations): Adjust.
8615 2001-12-05 Akim Demaille <akim@epita.fr>
8617 * src/lalr.c (transpose): Free the memory allocated to the
8618 argument, as it is replaced by the results by the unique caller.
8619 (build_relations): Merely invoke transpose: it handles the memory
8621 Improve variable locality.
8622 Avoid variables used as mere abbreviations.
8623 (compute_lookaheads): Use arrays instead of pointers.
8625 2001-12-05 Akim Demaille <akim@epita.fr>

8643 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
8644 the handling of squeue.
8645 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
8647 2001-12-05 Akim Demaille <akim@epita.fr>
8649 Because useless nonterminals are now kept alive (instead of being
8650 `destroyed'), we now sometimes examine them, and store information
8651 related to them. Hence we need to know their number, and adjust
8654 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
8656 * src/LR0.c (allocate_itemsets): The memory allocated to
8657 `symbol_count' was used for two different purpose: once to count
8658 the number of occurrences of each symbol, and later reassigned to
8659 `shift_symbol', containing the symbol that can be shifted from a
8661 Deobfuscate, i.e., allocate, use and free `symbol_count' here
8663 (new_itemsets): Allocate `shift_symbol' here.
8664 (allocate_itemsets): symbol_count includes useless nonterminals.
8666 (free_storage): Use `free', not `XFREE', for pointers that cannot
8669 2001-12-05 Akim Demaille <akim@epita.fr>
8671 * src/nullable.c (set_nullable): Deobfuscate the handling of
8673 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.

8677 * src/gram.c, src/gram.h (ritem_print): New.
8678 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
8679 (This useless function was defined only to work around VMS linkers
8680 that can't handle compilation units with variables only).
8681 * src/reduce.c (dump_grammar): Use it to trace the construction of
8684 2001-12-04 Paul Eggert <eggert@twinsun.com>
8686 * src/bison.simple (union yyalloc): Change member names
8687 to be the same as the stack names.
8688 (yyparse): yyptr is now union yyalloc *, not char *.
8689 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
8690 and may generate better code on some machines.
8691 (yystpcpy): Use prototype if __STDC__ is defined, not just
8692 if __cplusplus is defined.
8694 2001-11-30 Akim Demaille <akim@epita.fr>
8696 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
8697 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU

8700 Include WARNING_CFLAGS here.
8701 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
8702 before being defined.

8706 * lib/quotearg.h (quotearg_n, quotearg_n_style):
8707 First arg is int, not unsigned.
8708 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
8709 (SIZE_MAX, UINT_MAX): New macros.
8710 (quotearg_n_options): Abort if N is negative.
8711 Avoid overflow check on hosts where size_t is 64 bits and int
8712 is 32 bits, as overflow is impossible there.
8713 Fix off-by-one typo that caused unnecessary reallocation.
8715 2001-11-29 Paul Eggert <eggert@twinsun.com>
8717 Name space cleanup in generated parser.
8719 * doc/bison.texinfo (Bison Parser): Discuss system headers
8720 and their effect on the user name space.
8723 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

8725 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
8727 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
8728 on user names when possible.
8730 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
8731 Simplify test for whather <alloca.h> exists.
8733 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
8735 (<stdio.h>): Include if YYDEBUG.
8737 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
8738 ! defined (yyoverflow) && ! defined (yymemcpy).
8740 (yymemcpy, yyparse): Rename local variables as needed so that
8741 they all begin with 'yy'.
8743 (yystrlen, yystpcpy): New functions.
8745 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
8748 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
8749 instead of relying on string.h functions. Use YYSTACK_ALLOC
8750 and YYSTACK_FREE instead of malloc and free.
8752 2001-11-30 Akim Demaille <akim@epita.fr>
8754 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
8755 before their first uses.

8764 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
8765 if body instead of `;' to pacify GCC's warnings.
8767 2001-11-30 Akim Demaille <akim@epita.fr>
8769 Instead of mapping the LHS of unused rules to -1, keep the LHS
8770 valid, but flag the rules as invalid.
8772 * src/gram.h (rule_t): `useful' is a new member.
8773 * src/print.c (print_grammar): Adjust.
8774 * src/derives.c (set_derives): Likewise.
8775 * src/reader.c (packgram, reduce_output): Likewise.

8786 2001-11-30 Akim Demaille <akim@epita.fr>
8788 * src/reduce.c (nonterminals_reduce): Instead of throwing away
8789 useless nonterminals, move them at the end of the symbol arrays.
8790 (reduce_output): Adjust.

8803 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
8804 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
8806 (union yyalloc): New type.
8807 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
8808 an arbitrary restriction on hosts where size_t is wider than int.
8810 (yyparse): Don't dump core if alloca or malloc fails; instead, report
8811 a parser stack overflow. Allocate just one block of memory for all
8812 three stacks, instead of allocating three blocks; this typically is
8813 faster and reduces fragmentation.
8815 Do not limit the number of items in the stack to a value that fits
8816 in 'int', as this is an arbitrary limit on hosts with 64-bit
8817 size_t and 32-bit int.

10629 New, from fileutils 4.0.37.
10630 * configure.in: Require Autoconf 2.49c. I took some time before

10653 * src/lex.h: Rename all the tokens:
10654 s/\bENDFILE\b/tok_eof/g;
10655 s/\bIDENTIFIER\b/tok_identifier/g;
10657 Let them be enums, not #define, to ease debugging.

10681 introduces a guaranteed SEGV for semantic parsers.
10682 * doc/bison.texinfo: Document them.
10683 * tests/suite.at: Exercise these %options.
10685 2000-12-20 Akim Demaille <akim@epita.fr>

10902 (output_files): this.
10903 Use `obstack_save'.
10904 * src/main.c (main): Don't use `atexit' to register `done', since
10905 it no longer has to remove tmp files, just call `output_files'
10906 when there are no errors.
10908 2000-11-02 Akim Demaille <akim@epita.fr>

10978 * src/reader.c (copy_comment2): Expect the input stream to be on

10980 called after `//' or `/*' was read.
10981 (copy_comment, copy_definition, parse_union_decl, copy_action)
10982 (copy_guard): Adjust.
10984 2000-10-16 Akim Demaille <akim@epita.fr>
10986 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

11010 2000-10-04 Akim Demaille <akim@epita.fr>
11012 When a literal string is used to define two different tokens,
11013 `bison -v' segfaults.
11014 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
11016 * tests/regression.m4: New file.
11017 Include the core of the sample provided by Piotr Gackiewicz.
11018 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
11021 2000-10-04 Akim Demaille <akim@epita.fr>

11038 2000-10-02 Akim Demaille <akim@epita.fr>
11040 * src/derives.c, src/print.c, src/reduce.c: To ease the
11041 translation, move some `\n' out of the translated strings.
11043 2000-10-02 Akim Demaille <akim@epita.fr>
11045 The location tracking mechanism is precious for parse error
11046 messages. Nevertheless, it is enabled only when `@n' is used in
11047 the grammar, which is a different issue (you can use it in error
11048 message, but not in the grammar per se). Therefore, there should
11049 be another means to enable it.
11051 * src/getargs.c (getargs): Support `--locations'.
11052 (usage): Report it.
11053 * src/getargs.h (locationsflag): Export it.
11054 * src/lex.c (percent_table): Support `%locations'.
11055 * src/reader.c (yylsp_needed): Remove this variable, now replaced
11056 with `locationsflag'.
11057 * doc/bison.texinfo: Document `--locations' and `%locations'.
11059 * tests/calc.m4: Test it.
11061 For regularity of the names, replace each
11062 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
11063 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
11064 In addition replace each `flag' with `_flag'.
11066 2000-10-02 Akim Demaille <akim@epita.fr>
11068 Also test parse error messages, including with YYERROR_VERBOSE.
11070 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
11072 Use it to check the computations.
11073 Use it to check `nonassoc' is honored.
11074 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
11075 `--yyerror-verbose'.

11079 2000-10-02 Akim Demaille <akim@epita.fr>
11081 Test also `--verbose', `--defines' and `--name-prefix'. Testing
11082 the latter demonstrates a flaw in the handling of non debugging
11083 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
11084 was used in order to simplify:
11100 unfortunately this leads to a CPP conflict when
11101 `--name-prefix=foo' is used since it produces `#define yydebug
11104 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
11105 (YYDPRINTF): New macro.
11107 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
11109 Also test `--verbose', `--defines' and `--name-prefix'.

11113 Improve the readability of the produced parsers.
11115 * src/bison.s1: Formatting changes.
11116 Improve the comment related to the `$' mark.
11117 (yydefault): Don't fall through to `yyresume': `goto' there.
11118 * src/output.c (output_parser): When the `$' is met, skip the end
11120 New variable, `number_of_dollar_signs', to check there's exactly
11121 one `$' in the parser skeleton.
11123 2000-10-02 Akim Demaille <akim@epita.fr>
11125 * lib/xstrdup.c: New file, from the fileutils.
11126 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
11127 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
11128 instead of strlen + xmalloc + strcpy.
11129 * src/symtab.c (copys): Remove, use xstrdup instead.
11131 2000-10-02 Akim Demaille <akim@epita.fr>
11133 * src/gram.h (associativity): New enum type which replaces the
11134 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
11135 `right_assoc', `left_assoc' and `non_assoc'.
11136 Adjust all dependencies.
11137 * src/reader.c: Formatting changes.
11138 (LTYPESTR): Don't define it, use it as a literal in
11139 `reader_output_yylsp'.
11140 * src/symtab.h (symbol_class): New enum type which replaces the
11141 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
11142 `sunknown', `stoken and `snterm'.
11144 2000-10-02 Akim Demaille <akim@epita.fr>
11146 * src/getargs.c (fixed_outfiles): Rename as...
11147 (yaccflag): for consistency and accuracy.
11148 Adjust dependencies.
11150 2000-10-02 Akim Demaille <akim@epita.fr>
11152 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
11153 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
11154 difficult and introduced a lot of core dump. It turns out that
11155 Bison used an implementation of `xmalloc' based on `calloc', and
11156 at various places it does depend upon the initialization to 0. I
11157 have not tried to isolate the pertinent places, and all the former
11158 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
11159 someone should address this issue.
11161 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
11162 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

11174 2000-10-02 Akim Demaille <akim@epita.fr>

11181 Add support for `--statistics'.

11225 * src/files.c: Formatting changes.
11226 (tryopen, tryclose, openfiles): Rename as...

11256 * src/output.c (token_actions): Introduce a temporary array,
11257 YYDEFACT, that makes it possible for this function to use
11258 output_short_table.
11260 2000-10-02 Akim Demaille <akim@epita.fr>
11262 `user_toknums' is output as a `short[]' in `output.c', while it is
11263 defined as a `int[]' in `reader.c'. For consistency with the
11264 other output tables, `user_toknums' is now defined as a table of

11529 Change the handling of @s so that they behave exactly like $s.
11530 There is now a pseudo variable @$ (readble and writable), location
11531 of the lhs of the rule (by default ranging from the location of
11532 the first symbol of the rhs, to the location of the last symbol,
11533 or, if the rhs is empty, YYLLOC).

11568 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

12241 * src/reader.c (reader_output_yylsp):
12243 (readgram): Use `#if 0' around code that accepted %command
12244 inside grammar rules: The documentation doesn't allow it,
12245 and it will fail since the %command processors scan for the next %.
12246 (parse_token_decl): Extended the %token
12247 declaration to allow a multi-character symbol as an alias.
12248 (parse_thong_decl): New function.

12259 Revised and use multiple warnxxx functions to avoid using VARARGS1.
12260 (read_declarations): Improve the error message for
12261 an invalid character. Do not abort.
12262 (read_declarations, copy_guard, copy_action): Use
12263 printable_version to avoid unprintable characters in printed output.
12264 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.

12289 (lex): Use literalchar.
12290 (lex): Implemented "..." tokens.
12291 (literalchar, lex, parse_percent_token): Made tokenbuffer
12292 always contain the token. This includes growing the token
12293 buffer while reading an integer.
12294 (parse_percent_token): Replaced if-else statement with percent_table.
12295 (parse_percent_token): Added % declarations as another
12296 way to specify the flags -n, -l, and -r. Also added hooks for
12297 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
12298 major changes to files.c.
12299 (lex) Retain in the incoming stream a character following
12301 (skip_white_space, lex): Revised most error messages
12302 and changed fatal to warn to avoid aborting.

12305 * src/gram.h: Comment changes.
12307 * src/files.c (openfiles, open_extra_files, done):
