1 2002-11-16 Akim Demaille <akim@epita.fr>
3 Augment the similarity between GLR and LALR traces.
5 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
6 (YY_REDUCE_PRINT): New.
8 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11 state reached after the reduction/recovery, since...
12 (yyparse, yyprocessOneStack): Report the state we are entering in.
14 2002-11-16 Akim Demaille <akim@epita.fr>
16 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
17 Add support for --trace=skeleton.
18 * src/scan-skel.l: %option debug.
19 Scan strings of non-@ or \n instead of character by character.
20 (scan_skel): Handle trace_skeleton.
22 (@output_parser_name@, @output_header_name@): ``Restore'' their
23 support (used to be M4 macros).
24 * data/yacc.c: Quote larger chunks, a la glr.c.
25 * data/lalr1.cc: Likewise.
26 The header guards are no longer available, so use some other
27 string than `YYLSP_NEEDED'.
29 2002-11-16 Akim Demaille <akim@epita.fr>
31 Make the ``Printers and Destructors'' test more verbose, taking
32 `yacc.c''s behavior as (possibly wrong) reference.
34 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
35 instead of fprint on stdout.
36 Set and report the last_line of the symbols.
37 Consistently display values and locations.
39 2002-11-16 Paul Eggert <eggert@twinsun.com>
41 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
43 2002-11-15 Paul Eggert <eggert@twinsun.com>
45 * tests/actions.at (Actions after errors): New test case.
47 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
48 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
49 tests/action.at, tests/calc.at, tests/conflicts.at,
50 tests/cxx-type.at, tests/regression.at:
51 "parse error" -> "syntax error" for POSIX compatibility.
52 "parsing stack overflow..." -> "parser stack overflow" so
53 that code matches Bison documentation.
55 2002-11-15 Akim Demaille <akim@epita.fr>
57 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
58 take two BRACED_CODE, not two string_content.
59 Free the scanner's obstack when we are done.
61 * tests/calc.at: Adjust.
62 * doc/bison.texinfo: Adjust.
63 Also, make sure to include the `,' for these declarations.
65 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
67 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
68 definition; avoids potential autoreconf problems.

86 2002-11-14 Paul Eggert <eggert@twinsun.com>
88 * src/output.c (output_skeleton): Call xfopen instead of
89 duplicating xfopen's body.
91 Fix bugs reported by Nelson H. F. Beebe in
92 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
94 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
95 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
96 Group compiler. Instead, use "$CC -E bar.c". Include the .h
97 file twice in the grammar, as an extra check.
99 * tests/input.at (Torturing the Scanner): Surround the
100 backslash-newline tests with "#if 0", to make it less likely that
101 we'll run into compiler bugs. Bring back solitary \ inside
102 comment, but add a closing comment to work around HP C bug. Don't
103 test backslash-newline in C character constant. This should fix
104 the input.at bug reported by Nelson H. F. Beebe in
105 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
107 2002-11-14 Akim Demaille <akim@epita.fr>
109 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
110 status of the compiler.
111 Calling `exit 1' is no longer needed.
112 Reported by Nelson H. F. Beebe.
114 2002-11-14 Akim Demaille <akim@epita.fr>
116 * tests/atlocal.in (CPPFLAGS): We have config.h.

119 * tests/actions.at, tests/calc.at, tests/conflicts.at,
120 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
121 * tests/regression.at, tests/torture.at: Use them for all the
122 grammars that are to be compiled.
123 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
124 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
125 * doc/bison.texinfo (GLR Parsers): Document `inline'.
127 2002-11-14 Akim Demaille <akim@epita.fr>
129 * doc/bison.texinfo: Various formatting changes (alignments in
130 samples, additional @group/@end group, GCS in samples.
131 Use @deffn instead of simple @table to define the directives,
132 macros, variables etc.
134 2002-11-13 Paul Eggert <eggert@twinsun.com>
136 Fix some bugs reported by Albert Chin-A-Young in
137 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001881.html>.
139 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
140 -o c"; the HP C compiler chatters during compilation.
141 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
142 * tests/headers.at (export YYLTYPE): Likewise.
144 * tests/input.at (Torturing the Scanner): Remove lines containing
145 solitary backslashes, as they tickle a bug in the HP C compiler.
147 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
148 comments, since they're not portable. Use GNU coding style.
150 2002-11-13 Akim Demaille <akim@epita.fr>
152 * data/yacc.c: Leave bigger chunks of quoted text.
154 Use it to report symbol activities.
155 * data/glr.c (YYDSYMPRINTF): New.
158 2002-11-12 Paul Eggert <eggert@twinsun.com>
162 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
163 (yyglrReduce): Return yyok, not 0.
164 This should avoid the enumerated-type warnings reported
165 by Nelson H.F. Beebe in
166 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.
168 * lib/bbitset.h (BITSET_INLINE): Remove.
169 * lib/bitset.h [! BITSET_INLINE]: Remove.
170 (bitset_set, bitset_reset, bitset_test): Rename local vars
171 to avoid shadowing warnings by GCC.
173 * data/glr.c (inline): Remove #define. It's the user's
174 responsibility to #define it away, just like 'const'.
175 This fixes one of the bugs reported by Nelson H.F. Beebe in
176 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001873.html>.
178 * Makefile.maint (po-check): Scan .l and .y files instead of the
179 .c and the .h files that they generate. This fixes the bug
180 reported by Tim Van Holder in:
181 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
182 Look for N_ as well as for _. Try to avoid matching #define for
184 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
185 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
186 * src/scan-gram.l: Revamp regular expressions so that " and '
187 do not confuse xgettext.
189 * src/struniq.h (struniq_new): Do not declare the return type
190 to be 'const'; this violates the C standard.
191 * src/struniq.c (struniq_new): Likewise.
193 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
195 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
196 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
199 2002-11-12 Akim Demaille <akim@epita.fr>
201 * Makefile.maint: Sync with Autoconf:

218 2002-11-12 Akim Demaille <akim@epita.fr>
220 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
221 Use it to test the GLR parser.
223 2002-11-12 Akim Demaille <akim@epita.fr>
225 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
227 * data/glr.c (yystos): New.
228 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
230 (yyval): Don't define it, it is handled via M4.
231 (yyrecoverParseError): Free verbosely the discarded symbols.
232 * data/yacc.c (yysymprint): Remove, rather...
233 (b4_yysymprint_generate): invoke.
234 * data/c.m4 (b4_yysymprint_generate): New.
235 Accept pointers as arguments, as opposed to the version from
237 (b4_yydestruct_generate): Likewise.
238 * tests/cations.at (Printers and Destructors): Use Bison directives
239 instead of CPP macros.
240 Don't rely on internal details.
242 2002-11-12 Akim Demaille <akim@epita.fr>
244 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
245 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
246 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
247 it against YYEMPTY and so forth), work on yytoken (i.e., set
249 (yydestruct): Replace with a b4_yydestruct_generate invocation.
250 (b4_symbol_actions): Remove.
251 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
254 2002-11-12 Akim Demaille <akim@epita.fr>
256 * doc/bison.texinfo (Destructor Decl): New.
258 2002-11-12 Akim Demaille <akim@epita.fr>
260 * src/tables.c (tables_generate): Use free for pointers that
261 cannot be NULL, not XFREE.
262 (pack_vector): Use assert, not fatal, for bound violations.
263 * src/state.c (state_new): Likewise.
264 * src/reader.c (reader): Likewise.
265 * src/lalr.c (set_goto_map): Likewise.

269 2002-11-12 Akim Demaille <akim@epita.fr>
271 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
273 * src/scan-gram.l (last_string): Is global to the file, not to
275 * src/parse-gram.y (input): Don't append the epilogue here,
276 (epilogue.opt): do it here, and free the scanner's obstack.
277 * src/reader.c (epilogue_set): Rename as...
278 (epilogue_augment): this.
279 * data/c.m4 (b4_epilogue): Defaults to empty.
281 2002-11-12 Akim Demaille <akim@epita.fr>
283 * src/getargs.c (long_options): Remove duplicates.

337 2002-11-11 Paul Eggert <eggert@twinsun.com>
339 Revamp to fix many (but not all) of the C- and M4-related quoting
340 problems. Among other things, this fixes the Bison bug reported
341 by Jan Hubicka when processing the Bash grammar; see:
342 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001329.html>
344 Use new @ escapes consistently. Represent brackets with @{ and @}
345 rather than @<:@ and @:>@, since this works a bit better with dumb
346 editors like vi. Represent @ with @@, since @ is now consistently
347 an escape. Use @oline@ and @ofile@ rather than __oline__ and
348 __ofile__, to avoid unexpected expansions. Similarly, use @output
351 * data/c.m4 (b4_copyright): Omit file name from comment, since
352 the file name could contain "*/".
353 (b4_synclines_flag): Don't quote the 2nd argument; it should already
354 be quoted. All uses changed.
356 * data/glr.c: Use new @ escapes consistently.
357 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
358 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
359 Remove, since they couldn't handle arbitrary characters in file
361 * data/lalr1.cc: Likewise.
362 * data/yacc.c: Likewise.
364 * src/files.c (output_infix): Remove; all uses removed.
365 * src/files.h: Likewise.
367 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
368 mishandled funny characters in file names, and anyway it isn't
370 * data/yacc.c: Likewise.
371 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
373 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
374 * data/yacc.c: Likewise.
376 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
378 (muscle_init): Quote filename as a C string.
379 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
380 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
381 * src/output.c (escaped_file_name_output): New function.
382 (prepare_symbols): Quote tokens for M4.
383 (prepare): Don't insert output_infix, output_prefix,
384 output_parser_name, output_header_name; this is now down by scan-skel.
385 Insert skeleton as a C string.
387 * src/output.c (user_actions_output, symbol_destructors_output,
388 symbol_printers_output): Quote filenames for C and M4.
389 * src/reader.c (prologue_augment, epilogue_set): Likewise.
391 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
392 escapes other than \\ and \'; this simplifies the code.
393 (<SC_STRING>): Likewise, for \\ and \".
394 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
395 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
396 Use new escapes @{ and @} for [ and ].
398 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
400 Switch to new escape scheme, where @ is the escape character uniformly.
401 Abort if a stray escape character is found. Avoid unbounded input
402 buffer when parsing non-escaped text.
404 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
405 __oline__, #output, $@, and @{ do not have unintended meanings.
407 2002-11-09 Paul Eggert <eggert@twinsun.com>
409 Fix the test failure due to GCC warnings described in
410 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>.
411 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
412 evaluate to 0 if it's impossible for NINF to be in the respective
414 (yygetLRActions, yyrecoverParseError): Use them.
416 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
417 counted in the token inserted at end of file. Now takes
418 location_t *, not location_t, so that the location can be
419 adjusted. All uses changed.
421 * tests/regression.at (Invalid inputs): Adjust wording in
422 diagnostic to match the new behavior.
424 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
425 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
426 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
427 abort ();'. This reduces the runtime of the "Many lookaheads"
428 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
431 2002-11-07 Paul Eggert <eggert@twinsun.com>
433 * src/parse-gram.y (CHARACTER): Remove unused token.
436 * src/scan-gram.l: Remove stack option. We no longer use the
437 stack, since the stack was never deeper than 1; instead, use the
438 new auto var c_context to record the stacked value.
440 Remove nounput option. At an unexpected end of file, we now unput
441 the minimal input necessary to end cleanly; this simplifies the
444 Avoid unbounded token sizes where this is easy.
446 (unexpected_end_of_file): New function.
447 Use it to systematize the error message on unexpected EOF.
448 (last-string): Now auto, not static.
449 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
450 (scanner_last_string_free): Remove; not used.
451 (percent_percent_count): Move decl to just before use.
452 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
453 not the (never otherwised-used) CHARACTER.
455 2002-11-07 Akim Demaille <akim@epita.fr>
457 Let yyerror always receive the msg as last argument, so that
458 yyerror can be variadic.
460 * data/yacc.c (b4_yyerror_args): New.
461 Use it when calling yyerror.
462 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
463 Use it when calling yyerror.
464 * doc/bison.texinfo (Error Reporting): Adjust.

468 2002-11-06 Akim Demaille <akim@epita.fr>
470 #line should have quoted strings.
471 Ideally, this should be done by m4_quotearg.
473 * src/scan-skel.l: Include quotearg.h.
475 * src/output.c (symbol_printers_output)
476 (symbol_destructors_output): Quote the file name.
478 2002-11-06 Akim Demaille <akim@epita.fr>
480 * tests/regression.at (Invalid inputs): Adjust to the recent
483 2002-11-06 Akim Demaille <akim@epita.fr>

490 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
491 * src/output.c (user_actions_output): Likewise.
492 (prepare): Define 'b4_synclines_flag'.
493 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
495 2002-11-06 Akim Demaille <akim@epita.fr>
497 * src/main.c (main): Free `infile'.
498 * src/scan-gram.l (handle_syncline): New.
500 * src/output.c (user_actions_output, symbol_destructors_output)
501 (symbol_printers_output): Use the location's file name, not
503 * src/reader.c (prologue_augment, epilogue_set): Likewise.
505 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
507 * src/tables.c (matching_state): Don't allow states to match if
508 either has GLR conflict entries.
510 2002-11-05 Paul Eggert <eggert@twinsun.com>
512 * src/scan-gram.l: Use more accurate diagnostics, e.g.
513 "integer out of range" rather than "invalid value".
514 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
517 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
518 Also, remove one static variable in the scanner.
520 * src/scan-gram.l (braces_level): Now auto, not static.
521 Initialize to zero if the compiler is being picky.
522 (INITIAL): Clear braces_level instead of incrementing it.
523 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

526 * configure.ac: Define "lint" if --enable-gcc-warnings.
528 2002-11-05 Akim Demaille <akim@epita.fr>
530 * src/scan-gram.l: When it starts with `%', complain about the
531 whole directive, not just that `invalid character: %'.
533 2002-11-04 Akim Demaille <akim@epita.fr>
535 * Makefile.maint: Update from Autoconf.
536 (update, cvs-update, po-update, do-po-update): New.

540 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
542 Have yyerror `use' its arguments.
543 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
544 returns true when location & yacc & pure & parse-param.
545 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
547 2002-11-04 Akim Demaille <akim@epita.fr>
549 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
551 * src/scan-gram.l: Use [\'] instead of ['] to pacify
554 Use quote, not quote_n since LOCATION_PRINT no longer uses the
557 2002-11-03 Paul Eggert <eggert@twinsun.com>
559 * src/reader.c (get_merge_function, grammar_current_rule_check):
560 Use consistent diagnostics for reporting type name clashes.
561 Quote the types with <>, for consistency with Yacc.
562 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
564 2002-11-03 Akim Demaille <akim@epita.fr>
566 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
568 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
569 (b4_parse_param): Remove.
570 Use b4_identification.
571 Propagate b4_pure_args where needed to pass them to yyerror.
572 * data/glr.m4 (b4_parse_param): Remove.
573 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
574 (b4_lpure_formals): New.
575 Use b4_identification.
576 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
577 b4_user_formals and b4_user_args.
578 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
579 (yyreportAmbiguity): When using a pure parser, also need
580 the location, and the parse-params.
582 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
583 When using a pure parser, also need the parse-params.
585 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
586 (%pure-parser + %parse-param) LALR and GLR parsers.
587 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
588 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

590 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
591 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
592 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
593 * doc/bison.texinfo: Untabify the whole file.

597 Document %error-verbose, deprecate YYERROR_VERBOSE.
599 2002-11-03 Akim Demaille <akim@epita.fr>
601 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
602 AT_CHECK_CALC_GLR invocations to use % directives, instead of
603 command line options.
604 * tests/cxx-type.at: Formatting changes.
606 2002-11-03 Paul Eggert <eggert@twinsun.com>
608 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
609 to count columns correctly, and to check for invalid inputs.
611 Use mbsnwidth to count columns correctly. Account for tabs, too.
613 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
614 (extend_location): New function.
617 Handle CRLF in C code rather than in Lex code.
618 (YY_INPUT): New macro.
619 (no_cr_read): New function.
621 Scan UCNs, even though we don't fully handle them yet.

624 Handle backslash-newline correctly in C code.
625 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
626 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
628 (tag, splice): New EREs. Do not allow NUL or newline in tags.
629 Use {splice} wherever C allows backslash-newline.
630 YY_STEP after space, newline, vertical-tab.
631 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
633 (letter, id): Don't assume ASCII; e.g., spell out a-z.
635 ({int}, handle_action_dollar, handle_action_at): Check for integer
638 (YY_STEP): Omit trailing semicolon, so that it's more like C.
640 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
641 as well as \000. Check for UCHAR_MAX, not 255.
642 Allow \x with an arbitrary positive number of digits, as in C.
643 Check for overflow here.
644 Allow \? and UCNs, for compatibility with C.
646 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
647 with quote slot used by complain_at.
649 * tests/input.at: Add tests for backslash-newline, m4 quotes
650 in symbols, long literals, and funny escapes in strings.
652 * configure.ac (jm_PREREQ_MBSWIDTH): Add.

660 nor is backslash-newline allowed.
661 (Actions): Document that trigraphs have no special meaning.
663 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
666 2002-11-02 Paul Eggert <eggert@twinsun.com>
668 * src/reader.c: Don't include quote.h; not needed.

670 type clash diagnostic in grammar_current_rule_check.
672 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
673 bug in trigraph handling.
675 * src/output.c (prepare_symbols): When printing token names,
676 escape "[" as "@<:@" and likewise for "]".
678 * src/system.h (errno): Remove declaration, as we are now
679 assuming C89 or better, and C89 guarantees errno.
681 2002-10-30 Paul Eggert <eggert@twinsun.com>
683 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
684 Check for close failures.
685 * src/files.h (xfclose): Return void, not int, since it always
687 * src/files.c (xfclose): Likewise. Report I/O error if ferror
689 * src/output.c (output_skeleton): Use xfclose rather than fclose
690 and ferror. xfclose now checks ferror.
692 * data/glr.c (YYLEFTMOST_STATE): Remove.
693 (yyreportTree): Use a stack-based leftmost state. This avoids
694 our continuing battles with bogus warnings about initializers.
696 2002-10-30 Akim Demaille <akim@epita.fr>
698 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
701 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
703 * tests/glr-regr1.at: New test for reported regressions.
704 * tests/testsuite.at: Add glr-regr1.at test.

711 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
712 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
713 we use malloc. Don't assume 'A' through 'Z' are contiguous.
714 Don't assume strdup exists; POSIX says its an XSI extension.
715 Check for buffer overflow on input.
717 2002-10-24 Akim Demaille <akim@epita.fr>
719 * src/output.c (output_skeleton): Don't disable M4sugar comments
720 too soon: it results in comments being expanded.
721 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
724 2002-10-24 Akim Demaille <akim@epita.fr>
726 * data/yacc.c (m4_int_type): New.
727 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
728 char' as only yacc.c wants K&R portability.
729 * data/glr.c (yysigned_char): Remove.
730 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
731 Reported by Quoc Peyrot.
733 2002-10-23 Paul Eggert <eggert@twinsun.com>
735 * src/main.c (main): With --trace=time, report times even if a
736 non-fatal error occurs. Formerly, the times were reported in some
737 such cases but not in others.
738 * src/reader.c (reader): Just return if a complaint has been issued,
739 instead of exiting, so that 'main' can report times.
741 2002-10-22 Akim Demaille <akim@epita.fr>
743 * src/system.h: Include sys/types.
744 Reported by Bert Deknuydt.
746 2002-10-23 Paul Eggert <eggert@twinsun.com>
748 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
749 Suggested by Art Haas.

753 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
754 decl; not needed any more.
755 * src/main.c (main): Use return to exit, undoing yesterday's change.
756 The last OS that we could find where this wouldn't work is
757 SunOS 3.5, and that's too old to worry about now.
759 * data/glr.c (struct yyltype): Define members even when not
760 doing locations. This is more consistent with yacc.c, and it
761 works around the following bug reports:
762 http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
763 http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
764 and I hope it also fixes this bug report:
765 http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
767 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
768 @acronym consistently. Standardize on "Yacc" instead of "YACC",
769 "Algol" instead of "ALGOL". Give a bit more history about BNF.
771 2002-10-22 Akim Demaille <akim@epita.fr>
775 2002-10-21 Paul Eggert <eggert@twinsun.com>
777 Be consistent about 'bool'; the old code used an enum in one
778 module and an int in another, and this violates the C standard.
779 * m4/stdbool.m4: New file, from coreutils 4.5.3.
780 * configure.ac (AC_HEADER_STDBOOL): Add.
781 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
782 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
783 * src/symtab.c (hash_compare_symbol_t): Likewise.
784 * src/system.h (bool, false, true): Use a definition consistent
785 with ../lib/hash.c. All uses changed.
787 * src/complain.c (warning_issued): Renamed from warn_message_count,
788 so that we needn't worry about integer overflow (!).
789 Now of type bool. All uses changed.
790 (complaint_issued): Renamed from complain_message_count; likewise.
792 * src/main.c (main): Use exit to exit with failure.
794 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
796 * src/main.c (main): Likewise.
797 * src/getargs.c (getargs): Likewise.
798 * src/reader.c (reader): Likewise.
800 * src/getarg.c (getargs): Remove duplicate code for
801 "Try `bison --help'".
803 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
804 What was that "2" for?
806 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
807 * src/getargs.c (usage): Likewise.
809 * src/getargs.c (getargs): When there are too few operands, report
810 the last one. When there are too many, report the first extra
811 one. This is how diffutils does it.
813 2002-10-20 Paul Eggert <eggert@twinsun.com>
816 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
817 * src/complain.c (VA_START): Remove. Assume prototypes.
818 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
819 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
820 fatal): Assume prototypes.
821 * src/complain.h: Assume prototypes.
822 * src/system.h (PARAMS): Remove.
823 Include <limits.h> unconditionally, since it's guaranteeed even
824 for a freestanding C89 compiler.
825 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
826 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
828 2002-10-20 Akim Demaille <akim@epita.fr>
830 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
831 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

834 (yyprocessOneStack): Use them.
835 (yy_reduce_print): New.

843 (b4_c_function_def): this.
844 (b4_c_function_decl, b4_c_ansi_function_def)
845 (b4_c_ansi_function_decl): New.
846 Change the interpretation of the arguments: before `int, foo', now
848 * data/yacc.c (yyparse): Prototype and define thanks to these.
849 Adjust b4_c_function_def uses.
850 * data/glr.c (yyparse): Likewise, but ANSI only.
852 2002-10-20 Akim Demaille <akim@epita.fr>
854 * src/output.c (prepare): Move the definition of `tokens_number',
855 `nterms_number', `undef_token_number', `user_token_number_max'
857 (prepare_tokens): Here.
858 (prepare_tokens): Rename as...
859 (prepare_symbols): this.
860 (prepare): Move the definition of `rules_number' to...
861 (prepare_rules): here.
862 (prepare): Move the definition of `last', `final_state_number',
863 `states_number' to...
864 (prepare_states): here.
865 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
867 2002-10-20 Akim Demaille <akim@epita.fr>

871 2002-10-20 Akim Demaille <akim@epita.fr>
873 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
876 2002-10-20 Akim Demaille <akim@epita.fr>
878 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
879 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
881 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
883 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
884 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
887 2002-10-19 Paul Eggert <eggert@twinsun.com>
889 Do not create a temporary file, as that involves security and
890 cleanup headaches. Instead, use a pair of pipes.
891 Derived from a suggestion by Florian Krohm.
892 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
893 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

904 Check that m4sugar.m4 is readable, to avoid deadlock.
905 Check for pipe I/O error.
906 * src/scan-skel.l (readpipe): Remove decl.
907 (scan_skel): New function, to be used in place of m4_invoke.
908 Read from stream rather than file.
910 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
911 float, as this generates a warning on Solaris 8 + GCC 3.2 with
912 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
913 this generates a more-accurate value anyway.
915 * lib/timevar.c (timervar_accumulate): Rename locals to
916 avoid confusion with similarly-named more-global.
917 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
919 * src/output.c (prepare): Use xstrdup to convert char const *
920 to char *, to avoid GCC warning.
922 2002-10-19 Akim Demaille <akim@epita.fr>
924 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
925 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
926 Use them to have `calc.y' ready for %pure-parser.
927 * data/yacc.c (YYLEX): Pass a yylex return type to
930 2002-10-19 Akim Demaille <akim@epita.fr>
932 Prototype support of %lex-param and %parse-param.
934 * src/parse-gram.y: Add the definition of the %lex-param and
935 %parse-param tokens, plus their rules.
936 Drop the `_' version of %glr-parser.
938 * src/scan-gram.l (INITIAL): Scan them.
939 * src/muscle_tab.c: Comment changes.
940 (muscle_insert, muscle_find): Rename `pair' as `probe'.

943 Adjust all dependencies.
944 * src/muscle_tab.c (muscle_init): Adjust: use
945 MUSCLE_INSERT_STRING.
946 Initialize the obstack earlier.
947 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
948 (muscle_pair_list_grow): New.

954 2002-10-19 Akim Demaille <akim@epita.fr>
956 * src/getargs.c (usage): Take status as argument and exit
958 Report the traditional `Try ... --help' message when status != 0.
959 (usage, version): Don't take a FILE * as arg, it is pointless.
960 (getargs): When there is an incorrect number of arguments, make it
961 an error, and report it GNUlically thanks to `usage ()'.
963 2002-10-18 Paul Eggert <eggert@twinsun.com>
965 * data/glr.c (yyreportParseError): Don't assume that sprintf
966 yields the length of the printed string, as this is not true
967 on SunOS 4.1.4. Reported by Peter Klein.
969 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
970 * tests/conflicts.at (%nonassoc and eof): Likewise.
971 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
973 2002-10-17 Akim Demaille <akim@epita.fr>
975 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
976 * src/getargs.c (trace_types, trace_args): Adjust.

982 instead of an adhoc scheme.
983 * src/scan-gram.l: Remove trailing debugging code.
985 2002-10-16 Paul Eggert <eggert@twinsun.com>
987 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
990 * NEWS: Officially drop support for building Bison with K&R C,
991 since it didn't work anyway and it's not worth worrying about.
992 * Makefile.maint (wget_files): Remove ansi2knr.c.
993 (ansi2knr.c-url_prefix): Remove.
994 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
995 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
996 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
998 2002-10-15 Paul Eggert <eggert@twinsun.com>
1000 Stop using the "enum_" trick for K&R-style function definitions;
1001 it confused me, and I was the author! Instead, assume that people
1002 who want to use K&R C compilers (when using these modules in GCC,
1003 perhaps?) will run ansi2knr.
1005 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
1006 All uses of "enum_" changed to "enum ".
1007 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
1008 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
1010 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

1135 Let nondeterministic skeletons be usable with deterministic
1138 With the patch, GAWK compiled by GCC without -O2 passes its test
1139 suite using a GLR parser driven by LALR tables. It fails with -O2
1140 because `struct stat' gives two different answers on my machine:
1141 88 (definition of an auto var) and later 96 (memset on this var).
1142 Hence the stack is badly corrumpted. The headers inclusion is to
1143 blame: if I move the awk.h inclusion before GLR's system header
1144 inclusion, the two struct stat have the same size.

1181 (yygetLRActions): Map error action number from YYTABLE from

1219 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
1220 GCC version as of today, then merge Bison's changes.
1221 Change "GCC" to "Bison" in copyright notice. timevar.def's
1222 author is Akim, so change that too.

1722 this is a GCC extension and is not portable to other compilers.

1903 * src/LR0.c (save_reductions): Don't make the final state too
1904 different: save its reduction (accept) instead of having a state
1905 without any action (no shift or goto, no reduce).
1906 Note: the final state is now a ``regular'' state, i.e., the
1907 parsers now contain `reduce 0' as default reduction.
1908 Nevertheless, since they decide to `accept' when yystate =
1909 final_state, they still will not reduce rule 0.

1958 token_translations instead of `0'.
1959 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
1961 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
1962 for the time being: %locations ought to provide it to yyerror.
1964 2002-07-25 Akim Demaille <akim@epita.fr>
1966 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

4233 2002-02-14 Paul Eggert <eggert@twinsun.com>
4235 Remove the support for C++ namespace cleanliness; it was
4236 causing more problems than it was curing, since it didn't work

4240 * NEWS: Document this.

4333 (output_skeleton): Don't look for the skeleton location, let m4 do
4335 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
4337 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
4338 (prepare): Given that for the time being changesyntax is not
4339 usable in M4, rename the muscles using `-' to `_'.

4341 * src/output.h (actions_output, guards_output)
4342 (token_definitions_output): Adjust prototypes.

4369 2002-01-29 Paul Eggert <eggert@twinsun.com>
4371 * src/bison.simple (YYSIZE_T): Do not define merely because
4372 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

4377 Fix `%nonassoc and eof'.
4379 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
4380 which were not properly copied! Replace

4441 * src/system.h: Need to define __attribute__ away for non-GCC
4442 compilers as well (i.e. the vendor C compiler).
4443 Suggested by Albert Chin-A-Young.
4445 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
4447 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
4448 canonical definition.
4449 * src/system.h: Use the canonical definition for PARAMS (avoids
4450 a conflict with the macro from lib/hash.h).

4476 * src/files.c: Fix a few warnings.
4477 (get_extension_index): Remove, unused.
4479 2002-01-08 Akim Demaille <akim@epita.fr>
4481 * src/getargs.c (AS_FILE_NAME): New.
4482 (getargs): Use it to convert DOSish file names.
4483 * src/files.c (base_name): Rename as full_base_name to avoid
4484 clashes with `base_name ()'.
4485 (filename_split): New.
4486 (compute_base_names): N-th rewrite, using filename_split.
4488 2002-01-08 Akim Demaille <akim@epita.fr>
4490 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
4491 New, stolen from the Fileutils 4.1.
4492 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
4493 * configure.in: Check for the presence of memrchr, and of its
4496 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
4498 * lib/hash.h (__P): Added definition for this macro.
4499 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
4500 BUILT_SOURCES, to ensure they are generated first.
4501 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
4502 %error-verbose to allow bootstrapping with bison 1.30x.
4504 2002-01-06 Akim Demaille <akim@epita.fr>
4506 * src/reader.c (parse_braces): Don't fetch the next char, the
4507 convention is to fetch on entry.
4508 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
4509 'switch' without a following semicolon.
4510 * tests/regression.at (braces parsing): New.
4512 2002-01-06 Akim Demaille <akim@epita.fr>
4514 Bison is dead wrong in its RR conflict reports.
4516 * tests/torture.at (GNU Cim Grammar): New.
4517 * src/conflicts.c (count_rr_conflicts): Fix.
4519 2002-01-06 Akim Demaille <akim@epita.fr>
4521 Creating package.m4 from configure.ac causes too many problems.
4523 * tests/Makefile.am (package.m4): Create it by hand,
4524 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
4526 2002-01-06 Akim Demaille <akim@epita.fr>
4528 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
4531 2002-01-04 Paul Eggert <eggert@twinsun.com>
4533 * doc/bison.texinfo (Debugging):
4534 Remove YYSTDERR; it's no longer defined or used.
4535 Also, s/cstdio.h/cstdio/.
4537 2002-01-03 Akim Demaille <akim@epita.fr>
4539 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
4541 2002-01-03 Akim Demaille <akim@epita.fr>
4543 * src/parse-skel.y (process_skeleton): Don't bind the parser's
4544 tracing code to --trace, wait for a better --trace option, with
4547 2002-01-03 Akim Demaille <akim@epita.fr>
4549 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
4550 The ISO C++ standard is extremely clear about it: stderr is
4551 considered a macro, not a regular symbol (see table 94 `Header
4552 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
4553 Therefore std:: does not apply to it. It still does with fprintf.
4554 Also, s/cstdio.h/cstdio/.
4556 2002-01-03 Akim Demaille <akim@epita.fr>
4558 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
4559 for non system headers.
4561 2002-01-02 Akim Demaille <akim@epita.fr>
4563 Equip the skeleton chain with location tracking, runtime trace,
4564 pure parser and scanner.
4566 * src/parse-skel.y: Request a pure parser, locations, and prefix
4568 (%union): Having several members with the same type does not help
4569 type mismatches, simplify.
4570 (YYPRINT, yyprint): New.
4571 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
4574 * src/scan-skel.l: Adjust to these changes.
4575 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
4576 (LOCATION_PRINT, skel_control_t): New.
4578 2001-12-30 Akim Demaille <akim@epita.fr>
4580 * src/parse-skel.y: Get rid of the shift/reduce conflict:
4581 replace `gb' with BLANKS.
4582 * src/scan-skel.l: Adjust.
4584 2001-12-30 Akim Demaille <akim@epita.fr>
4586 * src/system.h: We don't need nor want bcopy.
4587 Throw away MS-DOS crap: we don't need getpid.
4588 * configure.in: We don't need strndup. It was even causing
4589 problems: because Flex includes the headers *before* us,
4590 _GNU_SOURCE is not defined by config.h, and therefore strndup was
4592 * lib/xstrndup.c: New.
4593 * src/scan-skel.l: Use it.
4594 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
4595 * src/parse-skel.y: Use %directives instead of #defines.
4597 2001-12-30 Akim Demaille <akim@epita.fr>
4599 * src/skeleton.h: New.
4600 * src/output.c (output_parser, output_master_parser): Remove, dead
4602 * src/output.h (get_lines_number, actions_output, guards_output)
4603 (token_definitions_output): Prototype them.
4604 * src/parse-skel.y: Add the license notice.
4605 Include output.h and skeleton.h.
4606 (process_skeleton): Returns void, and takes a single parameter.
4607 * src/scan-skel.l: Add the license notice.
4609 Don't use %option yylineno: it seems that then Flex imagines
4610 REJECT has been used, and therefore it won't reallocate its
4611 buffers (which makes no other sense to me than a bug). It results
4612 in warnings for `unused: yy_flex_realloc'.
4614 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
4616 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4617 (MUSCLE_INSERT_PREFIX): ...to there.
4618 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4619 (MUSCLE_INSERT_PREFIX): Move from here...
4621 * src/bison.hairy: Add a section directive. Put braces around muscle
4622 names. This parser skeleton is still broken, but Bison should not
4623 choke on a bad muscle 'syntax'.
4624 * src/bison.simple: Add a section directive. Put braces around muscle
4627 * src/files.h (strsuffix, stringappend): Add declarations.
4628 (tab_extension): Add declaration.
4629 (short_base_name): Add declaration.
4631 * src/files.c (strsuffix, stringappend): No longer static. These
4632 functions are used in the skeleton parser.
4633 (tab_extension): New.
4634 (compute_base_names): Use the computations done in this function
4635 to guess if the generated parsers should have '.tab' in their
4637 (short_base_name): No longer static.
4639 * src/output.c (output_skeleton): New.
4640 (output): Disable call to output_master_parser, and give a try to
4641 a new skeleton handling system.
4642 (guards_output, actions_output): No longer static.
4643 (token_definitions_output, get_lines_number): No longer static.
4645 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
4647 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
4650 * src/parse-skel.y: New file.
4651 * src/scan-skel.l: New file.
4653 2001-12-29 Akim Demaille <akim@epita.fr>
4655 %name-prefix is broken.
4657 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
4658 Adjust all dependencies.
4659 * tests/headers.at (export YYLTYPE): Strengthen this test: use
4662 Renaming yylval but not yylloc is not consistent. Now we do.
4664 * src/bison.simple: Prefix yylloc if used.
4665 * doc/bison.texinfo (Decl Summary): Document that.
4667 2001-12-29 Akim Demaille <akim@epita.fr>
4669 * doc/bison.texinfo: Promote `%long-directive' over
4671 Remove all references to fixed-output-files, yacc is enough.
4673 2001-12-29 Akim Demaille <akim@epita.fr>
4675 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
4676 user prologue. These are defaults.
4677 * tests/actions.at (Mid-rule actions): Make sure the user can
4678 define YYDEBUG and YYERROR_VERBOSE.
4680 2001-12-29 Akim Demaille <akim@epita.fr>
4682 * src/output.c (header_output): Don't forget to export YYLTYPE and
4684 * tests/headers.at (export YYLTYPE): New, make sure it does.
4685 * tests/regression.at (%union and --defines, Invalid CPP headers):
4687 * tests/headers.at: here.
4689 2001-12-29 Akim Demaille <akim@epita.fr>
4691 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
4693 2001-12-29 Akim Demaille <akim@epita.fr>
4695 * tests/actions.at (Mid-rule actions): Output on a single line
4698 2001-12-29 Akim Demaille <akim@epita.fr>
4700 * doc/bison.texinfo: Formatting changes.
4702 2001-12-29 Akim Demaille <akim@epita.fr>
4704 Don't store the token defs in a muscle, just be ready to output it
4705 on command. Now possible via `symbols'. Fixes a memory leak.
4707 * src/output.c (token_definitions_output): New.
4708 (output_parser, header_output): Use it.
4709 * src/reader.c (symbols_save): Remove.
4711 2001-12-29 Akim Demaille <akim@epita.fr>
4713 * src/bison.simple: Do not provide a default for YYSTYPE and
4714 YYLTYPE before the user's prologue. Otherwise it's hardly... a
4717 2001-12-29 Akim Demaille <akim@epita.fr>
4719 Mid-rule actions are simply... ignored!
4721 * src/reader.c (readgram): Be sure to attach mid-rule actions to
4722 the empty-rule associated to the dummy symbol, not to the host
4724 * tests/actions.at (Mid-rule actions): New.
4726 2001-12-29 Akim Demaille <akim@epita.fr>
4730 * src/reader.c (reader): Free grammar.
4732 2001-12-29 Akim Demaille <akim@epita.fr>
4736 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
4737 since it allocates it for each state, although only one is needed.
4738 (allocate_storage): Do it here.
4740 2001-12-29 Akim Demaille <akim@epita.fr>
4742 * src/options.h, src/options.c (create_long_option_table): Rename
4744 (long_option_table_new): this, with a clearer prototype.
4745 (percent_table): Remove, unused,
4746 * src/getargs.c (getargs): Adjust.
4748 2001-12-29 Akim Demaille <akim@epita.fr>
4750 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
4751 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
4754 2001-12-29 Akim Demaille <akim@epita.fr>
4756 * src/lalr.c (build_relations): Rename `states' as `states1'.
4757 Sorry, I don't understand exactly what it is, no better name...
4759 2001-12-29 Akim Demaille <akim@epita.fr>
4761 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
4762 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
4763 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
4766 2001-12-29 Akim Demaille <akim@epita.fr>
4768 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
4771 2001-12-29 Akim Demaille <akim@epita.fr>
4773 * src/reader.c, src/reader.h (user_toknums): Remove.
4774 Adjust all users to use symbols[i]->user_token_number.
4776 2001-12-29 Akim Demaille <akim@epita.fr>
4778 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
4779 Adjust all users to use symbols[i]->prec or ->assoc.
4781 2001-12-29 Akim Demaille <akim@epita.fr>
4783 * src/reader.c, src/reader.h (tags): Remove.
4784 Adjust all users to use symbols[i]->tag.
4786 2001-12-29 Akim Demaille <akim@epita.fr>
4788 * src/gram.h, src/gram.c (symbols): New, similar to state_table
4790 * src/reader.c (packsymbols): Fill this table.
4792 * src/conflicts.c (resolve_sr_conflict): Adjust.
4793 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
4795 Use symbols[i]->tag instead of tags[i].
4797 2001-12-29 Akim Demaille <akim@epita.fr>
4799 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
4800 In addition, put a comment in there, to replace...
4801 * tests/regression.at (%union and C comments): Remove.
4803 2001-12-29 Akim Demaille <akim@epita.fr>
4805 * tests/regression.at (Web2c Actions): Blindly move the actual
4806 output as expected output. The contents *seem* right to me, but I
4807 can't pretend reading perfectly parser tables... Nonetheless, all
4808 the other tests pass correctly, the table look OK, even though the
4809 presence of `$axiom' is to be noted: AFAICS it is useless (but
4812 2001-12-29 Akim Demaille <akim@epita.fr>
4814 * src/reader.c (readgram): Don't add the rule 0 if there were no
4815 rules read. In other words, add it _after_ having performed
4816 grammar sanity checks.
4817 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
4819 2001-12-29 Akim Demaille <akim@epita.fr>
4821 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
4822 visible, and some states have now a different number.
4824 2001-12-29 Akim Demaille <akim@epita.fr>
4826 * src/reader.c (readgram): Bind the initial rule's lineno to that
4828 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
4829 (Solved SR Conflicts): Adjust rule 0's line number.
4831 2001-12-29 Akim Demaille <akim@epita.fr>
4833 Fix the `GAWK Grammar' failure.
4835 * src/LR0.c (final_state): Initialize to -1 so that we do compute
4836 the reductions of the first state which was mistakenly confused
4837 with the final state because precisely final_state was initialized
4839 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
4840 now noticed by Bison.
4841 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
4842 have a reduction on $default.
4844 2001-12-29 Akim Demaille <akim@epita.fr>
4846 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
4848 * src/closure.c (print_closure): Likewise.
4849 * src/derives.c (print_derives): Likewise.
4850 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
4853 2001-12-29 Akim Demaille <akim@epita.fr>
4855 * src/lalr.c (lookaheads_print): New.
4856 (lalr): Call it when --trace-flag.
4857 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
4860 2001-12-29 Akim Demaille <akim@epita.fr>
4862 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
4863 when walking through ritem, even via rule->rhs.
4864 * src/reduce.c (dump_grammar, useful_production, reduce_output)
4865 (useful_production, useless_nonterminals): Likewise.
4866 (reduce_grammar_tables): Likewise, plus update nritems.
4867 * src/nullable.c (set_nullable): Likewise.
4868 * src/lalr.c (build_relations): Likewise.
4869 * tests/sets.at (Nullable): Adjust.
4870 Fortunately, now, the $axiom is no longer nullable.
4872 2001-12-29 Akim Demaille <akim@epita.fr>
4874 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
4876 * src/gram.c (ritem_longest_rhs): Likewise.
4877 * src/reduce.c (nonterminals_reduce): Likewise.
4878 * src/print_graph.c (print_graph): Likewise.
4879 * src/output.c (output_rule_data): Likewise.
4880 * src/nullable.c (set_nullable): Likewise.
4882 2001-12-29 Akim Demaille <akim@epita.fr>
4884 * src/output.c: Comment changes.
4886 2001-12-27 Paul Eggert <eggert@twinsun.com>
4888 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
4889 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
4890 Sparc, as they were causing more porting problems than the
4891 (minor) performance improvement was worth.
4893 Also, catch up with 1.31's YYSTD.
4895 2001-12-27 Akim Demaille <akim@epita.fr>
4897 * src/output.c (output_gram): Rely on nritems, not the
4898 0-sentinel. See below.
4899 Use -1 as separator, not 0.
4900 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
4901 Rely on -1 as separator in yyrhs, instead of 0.
4902 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
4903 twice `Now at end of input', therefore there are two lines less to
4906 2001-12-27 Akim Demaille <akim@epita.fr>
4908 * tests/regression.at (Unresolved SR Conflicts):
4909 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
4912 2001-12-27 Akim Demaille <akim@epita.fr>
4914 * src/LR0.c (new_state): Recognize the final state by the fact it
4915 is reached by eoftoken.
4916 (insert_start_shifting_state, insert_eof_shifting_state)
4917 (insert_accepting_state, augment_automaton): Remove, since now
4918 these states are automatically computed from the initial state.
4919 (generate_states): Adjust.
4920 * src/print.c: When reporting a rule number to the user, substract
4921 1, so that the axiom rule is rule 0, and the first user rule is 1.
4922 * src/reduce.c: Likewise.
4923 * src/print_graph.c (print_core): For the time being, just as for
4924 the report, depend upon --trace-flags to dump the full set of
4926 * src/reader.c (readgram): Once the grammar read, insert the rule
4927 0: `$axiom: START-SYMBOL $'.
4928 * tests/set.at: Adjust: rule 0 is now displayed, and since the
4929 number of the states has changed (the final state is no longer
4930 necessarily the last), catch up.
4932 2001-12-27 Akim Demaille <akim@epita.fr>
4934 Try to make the use of the eoftoken valid. Given that its value
4935 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
4936 is used instead of > 0 where appropriate, (ii), depend upon nritems
4937 instead of the 0-sentinel.
4939 * src/gram.h, src/gram.c (nritems): New.
4940 Expected to be duplication of nitems, but for the time being...
4941 * src/reader.c (packgram): Assert nritems and nitems are equal.
4942 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
4943 * src/closure.c (print_closure, print_fderives): Likewise.
4944 * src/gram.c (ritem_print): Likewise.
4945 * src/print.c (print_core, print_grammar): Likewise.
4946 * src/print_graph.c: Likewise.
4948 2001-12-27 Akim Demaille <akim@epita.fr>
4950 * src/main.c (main): If there are complains after grammar
4951 reductions, then output the report anyway if requested, then die.
4952 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
4953 * src/reader.c (eoftoken): New.
4954 (parse_token_decl): If the token being defined has value `0', it
4956 (packsymbols): No longer hack `tags' to insert `$' by hand.
4957 Be sure to preserve the value of the eoftoken.
4958 (reader): Make sure eoftoken is defined.
4959 Initialize nsyms to 0: now eoftoken is created just like the others.
4960 * src/print.c (print_grammar): Don't special case the eof token.
4961 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
4962 lie anyway, albeit pleasant.
4963 * tests/calc.at: Exercise error messages with eoftoken.
4964 Change the grammar so that empty input is invalid.
4965 Adjust expectations.
4966 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
4968 2001-12-27 Akim Demaille <akim@epita.fr>
4970 * configure.in: Check the protos of strchr ans strspn.
4971 Replace strchr if needed.
4972 * src/system.h: Provide the protos of strchr, strspn and memchr if
4974 * lib/strchr.c: New.
4975 * src/reader.c (symbols_save): Use strchr.
4977 2001-12-27 Akim Demaille <akim@epita.fr>
4979 * src/print.c, src/print_graph.c (escape): New.
4980 Use it to quote the TAGS outputs.
4981 * src/print_graph.c (print_state): Now errors are in red, and
4982 reductions in green.
4983 Prefer high to wide: output the state number on a line of its own.
4985 2001-12-27 Akim Demaille <akim@epita.fr>
4987 * src/state.h, src/state.c (reductions_new): New.
4988 * src/LR0.c (set_state_table): Let all the states have a
4989 `reductions', even if reduced to 0.
4990 (save_reductions): Adjust.
4991 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
4992 * src/print.c (print_reductions, print_actions): Adjust.
4993 * src/output.c (action_row): Adjust.
4995 2001-12-27 Akim Demaille <akim@epita.fr>
4997 * src/state.h, src/state.c (errs_new, errs_dup): New.
4998 * src/LR0.c (set_state_table): Let all the states have an errs,
4999 even if reduced to 0.
5000 * src/print.c (print_errs, print_reductions): Adjust.
5001 * src/output.c (output_actions, action_row): Adjust.

5004 2001-12-27 Akim Demaille <akim@epita.fr>
5006 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
5008 2001-12-27 Akim Demaille <akim@epita.fr>
5010 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
5011 * src/print.c: here.
5012 (lookaheadset, shiftset): New, used as additional storage by
5014 (print_results): Adjust.
5015 (print_shifts, print_gotos, print_errs): New, extracted from...
5016 (print_actions): here.
5017 * src/print_graph.c (print_actions): Remove dead code.
5019 2001-12-27 Akim Demaille <akim@epita.fr>
5021 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
5024 2001-12-27 Akim Demaille <akim@epita.fr>
5026 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
5027 (build_relations): Adjust.
5029 2001-12-27 Akim Demaille <akim@epita.fr>
5031 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
5034 2001-12-27 Akim Demaille <akim@epita.fr>
5036 * src/reader.c (packgram): Catch nitems overflows.
5038 2001-12-27 Akim Demaille <akim@epita.fr>
5040 * src/files.c, src/files.h (guard_obstack): Remove.
5041 * src/output.c (output): Adjust.
5042 * src/reader.c (parse_braces): New, factoring...
5043 (copy_action, copy_guard): these two which are renamed as...
5044 (parse_action, parse_guard): these.
5045 As a voluntary consequence, using braces around guards is now
5048 2001-12-27 Akim Demaille <akim@epita.fr>
5050 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
5051 * src/reader.c (symbol_list): `guard' and `guard_line' are new
5053 (symbol_list_new): Adjust.
5054 (copy_action): action_line is the first line, not the last.
5055 (copy_guard): Just as for actions, store the `action' only, not
5056 the switch/case/break flesh.
5057 Don't parse the user action that might follow the guard, let...
5058 (readgram): do it, i.e., now, there can be an action after a
5060 In other words the guard is just explicitly optional.
5062 * src/output.c (guards_output): New.
5063 (output_parser): Call it when needed.
5064 (output): Also free the guard and attrs obstacks.
5065 * src/files.c, src/files.h (obstack_save): Remove.
5066 (output_files): Remove.
5067 As a result, if one needs the former `.act' file, using an
5068 appropriate skeleton which requires actions and guards is now
5070 * src/main.c (main): Adjust.
5071 * tests/semantic.at: New.
5072 * tests/regression.at: Use `input.y' as input file name.
5073 Avoid 8+3 problems by requiring input.c when the test needs the

5078 * src/reader.c (symbol_list_new): Be sure to initialize all the
5081 2001-12-27 Akim Demaille <akim@epita.fr>
5083 All the hacks using a final pseudo state are now useless.
5085 * src/LR0.c (set_state_table): state_table holds exactly nstates.
5086 * src/lalr.c (nLA): New.
5087 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
5088 instead of lookaheadsp from the pseudo state (nstate + 1).
5090 2001-12-27 Akim Demaille <akim@epita.fr>
5092 * src/output.c (action_row, token_actions): Use a state_t instead
5093 of a integer, and nlookaheads instead of the following state's
5096 2001-12-27 Akim Demaille <akim@epita.fr>
5098 * src/conflicts.c (log_resolution, flush_shift)
5099 (resolve_sr_conflict, set_conflicts, solve_conflicts)
5100 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
5101 (conflicts_print, print_reductions): Use a state_t instead of an
5102 integer when referring to a state.
5103 As much as possible, depend upon nlookaheads, instead of the
5104 `lookaheadsp' member of the following state (since lookaheads of
5105 successive states are successive, the difference between state n + 1
5106 and n served as the number of lookaheads for state n).
5107 * src/lalr.c (add_lookback_edge): Likewise.
5108 * src/print.c (print_core, print_actions, print_state)
5109 (print_results): Likewise.

5112 * src/conflicts.h: Adjust.
5114 2001-12-27 Akim Demaille <akim@epita.fr>
5116 * src/bison.hairy: Formatting/comment changes.
5118 Remove `register' indications.
5119 Add plenty of `static'.
5121 2001-12-27 Akim Demaille <akim@epita.fr>
5123 * src/output.c (prepare): Drop the muscle `ntbase' which
5125 * src/bison.simple: Formatting/comment changes.
5126 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
5127 is an undocumented synonym.
5129 2001-12-22 Akim Demaille <akim@epita.fr>
5131 * src/output.c (output_table_data): Change the prototype to use
5132 `int' for array ranges: some invocations do pass an int, not a
5134 Reported by Wayne Green.
5136 2001-12-22 Akim Demaille <akim@epita.fr>
5138 Some actions of web2c.y are improperly triggered.
5139 Reported by Mike Castle.
5141 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

5143 (Web2c Report): this.
5144 (Web2c Actions): New.
5146 2001-12-22 Akim Demaille <akim@epita.fr>
5148 Reductions in web2c.y are improperly reported.
5149 Reported by Mike Castle.
5151 * src/conflicts.c (print_reductions): Fix.
5152 * tests/regression.at (Web2c): New.
5154 2001-12-18 Akim Demaille <akim@epita.fr>
5156 Some host fail on `assert (!"foo")', which expands to
5157 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
5158 Reported by Nelson Beebee.
5160 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
5161 `#define it_succeeded 0' and `assert (it_succeeded)'.
5163 2001-12-17 Marc Autret <autret_m@epita.fr>
5165 * src/bison.simple: Don't hard code the skeleton line and filename.
5166 * src/output.c (output_parser): Rename 'line' as 'output_line'.
5167 New line counter 'skeleton_line' (skeleton-line muscle).
5169 2001-12-17 Paul Eggert <eggert@twinsun.com>
5171 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
5172 YYDEBUG must be defined to a nonzero value.
5174 * src/bison.simple (yytname): Do not assume that the user defines
5175 YYDEBUG to a properly parenthesized expression.
5177 2001-12-17 Akim Demaille <akim@epita.fr>
5179 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
5180 nlookaheads is a new member.
5182 * src/lalr.h (nlookaheads): Remove this orphan declaration.
5183 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
5186 2001-12-17 Akim Demaille <akim@epita.fr>

5189 * src/main.c (main): Don't open/close files, nor invoke lex_free,
5191 * src/reader.c (reader): Do it.
5193 2001-12-17 Akim Demaille <akim@epita.fr>
5195 * src/conflicts.c (print_reductions): Formatting changes.
5197 2001-12-17 Akim Demaille <akim@epita.fr>
5199 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
5200 (flush_reduce): New.
5201 (resolve_sr_conflict): Adjust.
5203 2001-12-17 Akim Demaille <akim@epita.fr>
5205 * src/output.c (output_obstack): Be static and rename as...
5206 (format_obstack): this, to avoid any confusion with files.c's
5208 * src/reader.h (muscle_obstack): Move to...
5209 * src/output.h: here, since it's defined in output.c.
5211 2001-12-17 Akim Demaille <akim@epita.fr>
5213 * src/output.c (action_row, save_column, default_goto)
5214 (sort_actions, matching_state, pack_vector): Better variable
5217 2001-12-17 Akim Demaille <akim@epita.fr>
5219 * src/output.c: Various formatting changes.
5221 2001-12-17 Akim Demaille <akim@epita.fr>
5223 * src/files.c (output_files): Free the output_obstack.
5224 * src/main.c (main): Call print and print_graph conditionally.
5225 * src/print.c (print): Work unconditionally.
5226 * src/print_graph.c (print_graph): Work unconditionally.
5227 * src/conflicts.c (log_resolution): Output only if verbose_flag.
5229 2001-12-16 Marc Autret <autret_m@epita.fr>
5231 * src/output.c (actions_output): Fix. When we use %no-lines,
5232 there is one less line per action.
5234 2001-12-16 Marc Autret <autret_m@epita.fr>
5236 * src/bison.simple: Remove a useless #line directive.
5237 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
5238 * src/output.c (get_lines_number): New.
5239 (output_parser): Adjust, now takes care about the lines of a
5242 (actions_output): Computes the number of lines taken by actions.
5243 (output_master_parser): Insert new skeleton which is the name of
5244 the output parser file name.
5246 2001-12-15 Marc Autret <autret_m@epita.fr>
5248 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
5250 2001-12-15 Marc Autret <autret_m@epita.fr>
5252 * src/output.c (output_gram): Keep track of the hairy one.
5254 2001-12-15 Akim Demaille <akim@epita.fr>
5256 Make `make distcheck' work.
5258 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
5259 system.h which uses libgettext.h.
5261 2001-12-15 Akim Demaille <akim@epita.fr>
5263 * src/nullable.c (set_nullable): Useless rules must be skipped,
5264 otherwise, since we range over their symbols, we might look at a
5265 nonterminal which no longer ``exists'', i.e., it is not counted in
5266 `nvars', hence we overflow our arrays.
5268 2001-12-15 Akim Demaille <akim@epita.fr>
5270 The header can also be produced directly, without any obstack!
5273 * src/files.c, src/files.h (defines_obstack): Remove.
5274 (compute_header_macro): Global.
5275 (defines_obstack_save): Remove.
5276 * src/reader.c (parse_union_decl): No longer output to
5277 defines_obstack: its content can be found in the `stype' muscle
5279 (output_token_translations): Merge into...
5280 (symbols_output): this.
5282 (symbols_save): this.
5284 * src/output.c (header_output): New.
5287 2001-12-15 Akim Demaille <akim@epita.fr>
5289 * src/reader.c (parse_union_decl): Instead of handling two obstack
5290 simultaneously, use one to define the `stype' muscle, and use the
5291 value of the latter to fill defines_obstack.
5292 (copy_comment): Remove.
5293 (copy_comment2): Work for a single obstack.
5295 (copy_comment): this.
5297 2001-12-15 Akim Demaille <akim@epita.fr>
5299 * src/lex.c, src/lex.h (xgetc): No longer static.
5300 * src/reader.c (parse_union_decl): Revamp.
5302 2001-12-15 Akim Demaille <akim@epita.fr>
5304 Still making progress in separating Bison into (i) input, (ii)
5305 process, (iii) output: now we can directly output the parser file
5306 without using table_obstack at all.
5308 * src/files.c, src/files.h (table_obstack): Bye bye.
5309 (parser_file_name): New.
5310 * src/files.c (compute_output_file_names): Compute it.
5311 * src/output.c (actions_output, output_parser)
5312 (output_master_parser): To a file instead of an obstack.
5314 2001-12-15 Akim Demaille <akim@epita.fr>
5316 Attach actions to rules, instead of pre-outputting them to
5319 * src/gram.h (rule_t): action and action_line are new members.
5320 * src/reader.c (symbol_list): Likewise.
5321 (copy_action): Save the actions within the rule.
5322 (packgram): Save them in rule_table.
5323 * src/output.c (actions_output): New.
5324 (output_parser): Use it on `%%actions'.
5325 (output_rule_data): Don't free rule_table.
5327 (prepare): Don't save the `action' muscle.
5328 * src/bison.simple: s/%%action/%%actions/.
5330 2001-12-15 Akim Demaille <akim@epita.fr>
5332 * src/reader.c (copy_action): When --yacc, don't append a `;'
5333 to the user action: let it fail if lacking.
5334 Suggested by Arnold Robbins and Tom Tromey.
5336 2001-12-14 Akim Demaille <akim@epita.fr>
5338 * src/lex.c (literalchar): Simply return the char you decoded, non
5339 longer mess around with obstacks and int pointers.
5342 2001-12-14 Akim Demaille <akim@epita.fr>
5344 * src/lex.c (literalchar): Don't escape the special characters,
5345 just decode them, and keep them as char (before, eol was output as
5346 the 2 char string `\n' etc.).
5347 * src/output.c (output_rule_data): Use quotearg to output the
5350 2001-12-13 Paul Eggert <eggert@twinsun.com>
5352 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
5353 Do not infringe on the global user namespace when using C++.
5354 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
5355 All uses of `fprintf' and `stderr' changed.
5357 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
5359 2001-12-13 Akim Demaille <akim@epita.fr>
5361 The computation of nullable is broken: it doesn't handle empty
5364 * tests/torture.at (GNU AWK Grammar): New.
5365 * tests/sets.at (Nullable): New.
5366 * src/nullable.c (set_nullable): Instead of blindly looping over
5367 `ritems', loop over the rules, and then over their rhs's.
5369 Work around Autotest bugs.
5371 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
5372 frame, because Autotest understand lines starting with a `+' as
5373 traces from the shell. Then, they are not processed properly.
5374 Admittedly an Autotest bug, but we don't have time to wait for
5375 Autotest to catch up.
5376 * tests/regression.at (Broken Closure): Adjust to the new table
5379 * tests/sets.at: here.
5381 2001-12-13 Akim Demaille <akim@epita.fr>
5383 * src/closure.c (closure): Use nrules instead of playing tricks
5386 2001-12-13 Akim Demaille <akim@epita.fr>
5388 * src/print.c (print_actions): Output the handling of `$' as the
5389 traces do: shifting the token EOF. Before EOF was treated as a
5391 * tests/regression.at: Adjust some tests.
5392 * src/print_graph.c (print_core): Complete the set of items via
5393 closure. The next-to-final and final states are still unsatisfying,
5394 but that's to be addressed elsewhere.
5395 No longer output the rule numbers, but do output the state number.
5396 A single loop for the shifts + gotos is enough, but picked a
5397 distinct color for each.
5398 (print_graph): Initialize and finalize closure.
5400 2001-12-13 Akim Demaille <akim@epita.fr>
5402 * src/reader.c (readgram): Remove dead code, an strip useless
5404 (get_type): Remove, unused.
5406 2001-12-12 Akim Demaille <akim@epita.fr>
5408 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
5409 on that of lib/error.c.
5411 2001-12-12 Akim Demaille <akim@epita.fr>
5413 Some hosts don't like `/' in includes.
5415 * src/system.h: Include libgettext.h without qualifying the path.
5416 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
5419 2001-12-11 Marc Autret <autret_m@epita.fr>
5421 * src/output.c (output_parser): Remove useless muscle.
5423 2001-12-11 Marc Autret <autret_m@epita.fr>
5425 * src/bison.simple: Remove #line just before %%epilogue. It
5426 is now handled in ...
5427 * src/reader.c (read_additionnal_code): Add the output of a
5428 #line for the epilogue.
5430 2001-12-10 Marc Autret <autret_m@epita.fr>
5432 * src/reader.c (copy_definition): Re-use CPP-outed code which
5433 replace precedent remove.
5434 * src/bison.simple: Remove #line before %%prologue because
5435 %%input-line is wrong at this time.
5437 2001-12-10 Marc Autret <autret_m@epita.fr>
5439 * src/reader.c (symbols_output): Clean up.
5440 * src/output.c (output_gram, output): Clean up.
5442 2001-12-10 Akim Demaille <akim@epita.fr>
5444 * src/lalr.c (initialize_lookaheads): New. Extracted from...
5445 * src/LR0.c (set_state_table): here.
5446 * src/lalr.c (lalr): Call it.
5448 2001-12-10 Akim Demaille <akim@epita.fr>
5450 * src/state.h (shifts): Remove the `number' member: shifts are
5451 attached to state, hence no longer need to be labelled with a
5454 2001-12-10 Akim Demaille <akim@epita.fr>
5456 Now that states have a complete set of members, the linked list of
5457 shifts is useless: just fill directly the state's shifts member.
5459 * src/state.h (shifts): Remove the `next' member.
5460 * src/LR0.c (first_state, last_state): Remove.
5462 (augment_automaton): Don't look for the shifts that must be added
5463 a shift on EOF: it is those of the state we looked for! But now,
5464 since shifts are attached, it is no longer needed to looking
5465 merely by its id: its number.
5467 2001-12-10 Akim Demaille <akim@epita.fr>
5469 * src/LR0.c (augment_automaton): Better variable locality.
5470 Remove an impossible branch: if there is a state corresponding to
5471 the start symbol being shifted, then there is shift for the start
5472 symbol from the initial state.
5474 2001-12-10 Akim Demaille <akim@epita.fr>
5476 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
5477 only when appropriate: when insert_start_shifting_state' is not
5479 * tests/regression.at (Rule Line Numbers): Adjust.
5481 2001-12-10 Akim Demaille <akim@epita.fr>
5483 * src/LR0.c (augment_automaton): Now that all states have shifts,
5484 merge the two cases addition shifts to the initial state.
5486 2001-12-10 Akim Demaille <akim@epita.fr>
5488 * src/lalr.c (set_state_table): Move to...
5490 * src/lalr.c (lalr): Don't call it...
5491 * src/LR0.c (generate_states): do it.
5492 * src/LR0.h (first_state): Remove, only the table is used.
5494 2001-12-10 Akim Demaille <akim@epita.fr>
5496 * src/LR0.h (first_shift, first_reduction): Remove.
5497 * src/lalr.c: Don't use first_shift: find shifts through the
5500 2001-12-10 Akim Demaille <akim@epita.fr>
5502 * src/LR0.c: Attach shifts to states as soon as they are
5504 * src/lalr.c (set_state_table): Instead of assigning shifts to
5505 state, just assert that the mapping was properly done.
5507 2001-12-10 Akim Demaille <akim@epita.fr>
5509 * src/LR0.c (insert_start_shift): Rename as...
5510 (insert_start_shifting_state): this.
5511 (insert_eof_shifting_state, insert_accepting_state): New.
5512 (augment_automaton): Adjust.
5513 Better locality of the variables.
5514 When looking if the start_symbol is shifted from the initial
5515 state, using `while (... symbol != start_symbol ...)' sounds
5516 better than `while (... symbol < start_symbol ...)': If fail
5517 to see how the order between symbols could be relevant!
5519 2001-12-10 Akim Demaille <akim@epita.fr>
5521 * src/getargs.h: Don't declare `spec_name_prefix' and
5522 `spec_file_prefix', declared by src/files.h.
5523 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
5524 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
5525 * src/output.c (prepare): Adjust.
5526 * src/reader.c (symbols_output): Likewise.
5527 * src/vmsgetargs.c: Vaguely adjust, but who cares?
5529 2001-12-10 Akim Demaille <akim@epita.fr>
5531 * src/muscle_tab.c (muscle_init): NULL is a better default than
5534 2001-12-10 Akim Demaille <akim@epita.fr>
5536 * src/reader.c (reader): Calling symbols_output once is enough.

5540 Now that states have a complete set of members, the linked list of
5541 reductions is useless: just fill directly the state's reductions
5544 * src/state.h (struct reductions): Remove member `number' and
5546 * src/LR0.c (first_reduction, last_reduction): Remove.
5547 (save_reductions): Don't link the new reductions, store them in
5549 * src/lalr.c (set_state_table): No need to attach reductions to
5550 states, it's already done.
5551 * src/output.c (output_actions): No longer free the shifts, then
5552 the reductions, then the states: free all the states and their
5555 2001-12-10 Akim Demaille <akim@epita.fr>
5557 * src/options.c (OPTN, DRTV, BOTH): New.
5558 (option_table): Use them.
5560 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
5561 the job of system.h.
5562 * src/options.c: Don't include stdio.h and xalloc.h for the same
5565 2001-12-10 Akim Demaille <akim@epita.fr>
5567 * src/output.c (output, prepare): Make sure the values of the

5587 * tests/Makefile.am: Adjust.
5589 2001-12-10 Akim Demaille <akim@epita.fr>
5591 One structure for states is enough, even though theoretically
5592 there are LR(0) states and LALR(1) states.
5594 * src/lalr.h (state_t): Remove.
5595 (state_table): Be state_t **, not state_t *.
5596 * src/state.h (core, CORE_ALLOC): Rename as...

5598 Add the LALR(1) members: shifts, reductions, errs.
5599 * src/LR0.c (state_table): Rename as...
5600 (state_hash): this, to avoid name clashes with the global
5602 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c

5605 2001-12-10 Akim Demaille <akim@epita.fr>
5607 Bison dumps core on bash.y.
5608 Reported by Pascal Bart.
5610 * src/warshall.c (bitmatrix_print): New.
5612 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
5613 j must be the outer loop.

5616 2001-12-05 Akim Demaille <akim@epita.fr>
5618 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and

5630 2001-12-05 Akim Demaille <akim@epita.fr>
5632 * src/reduce.c (reduce_grammar_tables): No longer disable the
5633 removal of useless rules via CPP but via `if (0)', so that the
5634 compiler still check the code is valid.
5635 For instance, it should have noticed `rline' no longer exists: use
5636 the `line' member of rule_t.
5637 * src/gram.c (dummy, rline): Remove, unused.
5639 2001-12-05 Akim Demaille <akim@epita.fr>
5641 * src/output.c (pack_vector): Use assert, not berror.
5642 * src/main.c (berror): Remove, unused.
5644 2001-12-05 Akim Demaille <akim@epita.fr>
5646 New experimental feature: if --verbose --trace output all the
5647 items of a state, not only its kernel.
5649 * src/print.c (print_core): If `trace_flag', then invoke closure
5650 before outputting the items of the state (print_core is no longer
5651 a correct name them).

5665 2001-12-05 Akim Demaille <akim@epita.fr>
5667 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
5668 indexed by nonterminals.
5670 2001-12-05 Akim Demaille <akim@epita.fr>
5672 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

5692 locality, BITISSET, RESETBIT etc.
5694 2001-12-05 Akim Demaille <akim@epita.fr>
5696 Pessimize the code to simplify it: from now on, all the states
5697 have a valid SHIFTS, which NSHIFTS is possibly 0.
5699 * src/LR0.c (shifts_new): Be global and move to..
5700 * src/state.c, src/state.h: here.
5701 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

5765 2001-12-05 Akim Demaille <akim@epita.fr>
5767 * src/lalr.c (maxrhs): Move to...
5768 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
5769 * src/lalr.c (build_relations): Adjust.
5771 2001-12-05 Akim Demaille <akim@epita.fr>
5773 * src/lalr.c (transpose): Free the memory allocated to the
5774 argument, as it is replaced by the results by the unique caller.
5775 (build_relations): Merely invoke transpose: it handles the memory
5777 Improve variable locality.

5797 2001-12-05 Akim Demaille <akim@epita.fr>
5799 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
5800 the handling of squeue.
5801 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5803 2001-12-05 Akim Demaille <akim@epita.fr>
5805 Because useless nonterminals are now kept alive (instead of being
5806 `destroyed'), we now sometimes examine them, and store information
5807 related to them. Hence we need to know their number, and adjust
5810 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
5812 * src/LR0.c (allocate_itemsets): The memory allocated to
5813 `symbol_count' was used for two different purpose: once to count
5814 the number of occurrences of each symbol, and later reassigned to
5815 `shift_symbol', containing the symbol that can be shifted from a
5817 Deobfuscate, i.e., allocate, use and free `symbol_count' here
5819 (new_itemsets): Allocate `shift_symbol' here.
5820 (allocate_itemsets): symbol_count includes useless nonterminals.
5822 (free_storage): Use `free', not `XFREE', for pointers that cannot
5825 2001-12-05 Akim Demaille <akim@epita.fr>
5827 * src/nullable.c (set_nullable): Deobfuscate the handling of
5829 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5831 2001-12-05 Akim Demaille <akim@epita.fr>
5833 * src/gram.c, src/gram.h (ritem_print): New.
5834 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
5835 (This useless function was defined only to work around VMS linkers
5836 that can't handle compilation units with variables only).
5837 * src/reduce.c (dump_grammar): Use it to trace the construction of
5840 2001-12-04 Paul Eggert <eggert@twinsun.com>
5842 * src/bison.simple (union yyalloc): Change member names
5843 to be the same as the stack names.
5844 (yyparse): yyptr is now union yyalloc *, not char *.
5845 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
5846 and may generate better code on some machines.
5847 (yystpcpy): Use prototype if __STDC__ is defined, not just
5848 if __cplusplus is defined.
5850 2001-11-30 Akim Demaille <akim@epita.fr>
5852 * configure.in (WARNING_CFLAGS): Add -Werror when possible.

5856 Include WARNING_CFLAGS here.
5857 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

5865 (SIZE_MAX, UINT_MAX): New macros.
5866 (quotearg_n_options): Abort if N is negative.
5867 Avoid overflow check on hosts where size_t is 64 bits and int
5868 is 32 bits, as overflow is impossible there.
5869 Fix off-by-one typo that caused unnecessary reallocation.
5871 2001-11-29 Paul Eggert <eggert@twinsun.com>
5873 Name space cleanup in generated parser.
5875 * doc/bison.texinfo (Bison Parser): Discuss system headers
5876 and their effect on the user name space.
5879 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

5881 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
5883 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
5884 on user names when possible.
5886 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
5887 Simplify test for whather <alloca.h> exists.
5889 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
5891 (<stdio.h>): Include if YYDEBUG.
5893 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
5894 ! defined (yyoverflow) && ! defined (yymemcpy).
5896 (yymemcpy, yyparse): Rename local variables as needed so that
5897 they all begin with 'yy'.
5899 (yystrlen, yystpcpy): New functions.
5901 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
5904 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
5905 instead of relying on string.h functions. Use YYSTACK_ALLOC
5906 and YYSTACK_FREE instead of malloc and free.
5908 2001-11-30 Akim Demaille <akim@epita.fr>
5910 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
5911 before their first uses.

5914 2001-11-30 Akim Demaille <akim@epita.fr>
5916 * tests/reduce.at (Useless Nonterminals): Fix.
5918 2001-11-30 Akim Demaille <akim@epita.fr>
5920 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
5921 if body instead of `;' to pacify GCC's warnings.
5923 2001-11-30 Akim Demaille <akim@epita.fr>
5925 Instead of mapping the LHS of unused rules to -1, keep the LHS
5926 valid, but flag the rules as invalid.
5928 * src/gram.h (rule_t): `useful' is a new member.
5929 * src/print.c (print_grammar): Adjust.
5930 * src/derives.c (set_derives): Likewise.
5931 * src/reader.c (packgram, reduce_output): Likewise.

5942 2001-11-30 Akim Demaille <akim@epita.fr>
5944 * src/reduce.c (nonterminals_reduce): Instead of throwing away
5945 useless nonterminals, move them at the end of the symbol arrays.
5946 (reduce_output): Adjust.

5959 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
5960 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
5962 (union yyalloc): New type.
5963 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
5964 an arbitrary restriction on hosts where size_t is wider than int.
5966 (yyparse): Don't dump core if alloca or malloc fails; instead, report
5967 a parser stack overflow. Allocate just one block of memory for all
5968 three stacks, instead of allocating three blocks; this typically is
5969 faster and reduces fragmentation.
5971 Do not limit the number of items in the stack to a value that fits
5972 in 'int', as this is an arbitrary limit on hosts with 64-bit
5973 size_t and 32-bit int.
5975 2001-11-29 Marc Autret <autret_m@epita.fr>
5977 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
5978 of defining YYERROR_VERBOSE.

5991 * src/output.c (error_verbose): Define here.
5992 (prepare): Echo name modification.
5993 * src/getargs.h: Clean its extern declaration.
5994 * src/getargs.c (error_verbose_flag): Remove.
5995 (getargs): Remove case 'e'.

6028 2001-11-28 Akim Demaille <akim@epita.fr>
6030 * src/closure.c (closure): Instead of looping over word in array
6031 then bits in words, loop over bits in array.
6033 2001-11-28 Akim Demaille <akim@epita.fr>
6035 * src/closure.c (closure): No longer optimize the special case
6036 where all the bits of `ruleset[r]' are set to 0, to make the code
6039 2001-11-28 Akim Demaille <akim@epita.fr>
6041 * src/closure.c (closure): `r' and `c' are new variables, used to
6042 de-obfuscate accesses to RULESET and CORE.
6044 2001-11-28 Akim Demaille <akim@epita.fr>
6046 * src/reduce.c (reduce_print): Use ngettext.

6055 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
6056 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
6057 as all tags are free'ed afterwards.
6060 2001-11-27 Paul Eggert <eggert@twinsun.com>
6062 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
6063 use alloca when we didn't want to, and vice versa.
6065 2001-11-27 Marc Autret <autret_m@epita.fr>
6067 * src/muscle_tab.c (muscle_init): Remove 'verbose' muscle

7778 * src/conflicts.c (conflict_report): Be sure not to append to res
7779 between two calls, which could happen if both first sprintf were
7780 skipped, but not the first cp += strlen.

7785 New, from fileutils 4.0.37.
7786 * configure.in: Require Autoconf 2.49c. I took some time before
7787 making this decision. This is the only way out for portability
7788 issues in Bison, it would mean way too much duplicate effort to
7789 import in Bison features implemented in 2.49c since 2.13.
7790 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
7792 2001-02-02 Akim Demaille <akim@epita.fr>

7809 * src/lex.h: Rename all the tokens:
7810 s/\bENDFILE\b/tok_eof/g;
7811 s/\bIDENTIFIER\b/tok_identifier/g;

7826 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

7831 * src/reader.c (read_declarations): Adjust.
7832 * src/files.c (open_files): Don't call `compute_base_names', don't
7833 compute `attrsfile' since they depend upon data which might be
7834 *in* the input file now.
7835 (output_files): Do it here.
7836 * src/output.c (output_headers): Document the fact that this patch
7837 introduces a guaranteed SEGV for semantic parsers.

7839 * tests/suite.at: Exercise these %options.

7914 * src/output.c (output_parser): Compute the `#line' lines when
7916 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
7917 Suggested by Hans Aberg.
7919 2000-12-19 Akim Demaille <akim@epita.fr>

7946 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

7974 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
7975 prevents type checking.
7976 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
7977 cast the value to (void *): assigning a `foo *' to a `void *'

7980 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

7988 * tests/atgeneral.m4: Update from CVS Autoconf.
7990 2000-11-17 Akim Demaille <akim@epita.fr>
7992 * tests/regression.m4 (%union and --defines): New test,
7993 demonstrating a current bug in the obstack implementation.
7995 2000-11-17 Akim Demaille <akim@epita.fr>
7997 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

8024 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
8025 argument `data' for consistency with the prototypes.
8027 (obstack_copy, obstack_copy0): Rename the second argument as
8028 `address' for consistency. Qualify it `const'.
8029 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
8030 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
8031 `const' their input argument (`data' or `address').
8032 Adjust the corresponding macros to include `const' in casts.
8034 2000-11-03 Akim Demaille <akim@epita.fr>
8036 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
8037 s/PFILE1/BISON_HAIRY/.

8042 For some reason, this was not applied.
8044 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
8045 `unlink': it's no longer used.
8047 2000-11-03 Akim Demaille <akim@epita.fr>
8049 * src/files.c (skeleton_find): New function, eved out of...

8056 * src/files.c (obstack_save): New function.
8057 (done): Rename as...
8058 (output_files): this.
8060 * src/main.c (main): Don't use `atexit' to register `done', since
8061 it no longer has to remove tmp files, just call `output_files'
8062 when there are no errors.
8064 2000-11-02 Akim Demaille <akim@epita.fr>
8066 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
8067 `unlink': it's no longer used.
8068 * src/files.h: Formatting changes.
8070 2000-11-02 Akim Demaille <akim@epita.fr>

8135 called after `//' or `/*' was read.
8136 (copy_comment, copy_definition, parse_union_decl, copy_action)
8137 (copy_guard): Adjust.
8139 2000-10-16 Akim Demaille <akim@epita.fr>
8141 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

8147 (copy_guard, copy_action): Use it.
8149 2000-10-16 Akim Demaille <akim@epita.fr>
8151 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:

8165 2000-10-04 Akim Demaille <akim@epita.fr>
8167 When a literal string is used to define two different tokens,
8168 `bison -v' segfaults.
8169 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
8171 * tests/regression.m4: New file.
8172 Include the core of the sample provided by Piotr Gackiewicz.
8173 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
8176 2000-10-04 Akim Demaille <akim@epita.fr>
8178 * src/reader.c (parse_expect_decl): Keep `count' within the size
8182 2000-10-02 Paul Eggert <eggert@twinsun.com>

8196 translation, move some `\n' out of the translated strings.
8198 2000-10-02 Akim Demaille <akim@epita.fr>
8200 The location tracking mechanism is precious for parse error
8201 messages. Nevertheless, it is enabled only when `@n' is used in
8202 the grammar, which is a different issue (you can use it in error
8203 message, but not in the grammar per se). Therefore, there should
8204 be another means to enable it.
8206 * src/getargs.c (getargs): Support `--locations'.
8208 * src/getargs.h (locationsflag): Export it.
8209 * src/lex.c (percent_table): Support `%locations'.
8210 * src/reader.c (yylsp_needed): Remove this variable, now replaced
8211 with `locationsflag'.
8212 * doc/bison.texinfo: Document `--locations' and `%locations'.
8214 * tests/calc.m4: Test it.
8216 For regularity of the names, replace each
8217 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
8218 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
8219 In addition replace each `flag' with `_flag'.
8221 2000-10-02 Akim Demaille <akim@epita.fr>
8223 Also test parse error messages, including with YYERROR_VERBOSE.
8225 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
8227 Use it to check the computations.
8228 Use it to check `nonassoc' is honored.
8229 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
8230 `--yyerror-verbose'.
8231 (_AT_CHECK_CALC): Adjust to this option.
8232 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
8234 2000-10-02 Akim Demaille <akim@epita.fr>
8236 Test also `--verbose', `--defines' and `--name-prefix'. Testing
8237 the latter demonstrates a flaw in the handling of non debugging
8238 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
8239 was used in order to simplify:
8255 unfortunately this leads to a CPP conflict when
8256 `--name-prefix=foo' is used since it produces `#define yydebug
8259 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
8260 (YYDPRINTF): New macro.
8262 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
8264 Also test `--verbose', `--defines' and `--name-prefix'.

8273 * src/output.c (output_parser): When the `$' is met, skip the end
8275 New variable, `number_of_dollar_signs', to check there's exactly
8276 one `$' in the parser skeleton.
8278 2000-10-02 Akim Demaille <akim@epita.fr>
8280 * lib/xstrdup.c: New file, from the fileutils.

8288 * src/gram.h (associativity): New enum type which replaces the
8289 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
8290 `right_assoc', `left_assoc' and `non_assoc'.
8291 Adjust all dependencies.

8307 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
8308 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
8309 difficult and introduced a lot of core dump. It turns out that
8310 Bison used an implementation of `xmalloc' based on `calloc', and
8311 at various places it does depend upon the initialization to 0. I
8312 have not tried to isolate the pertinent places, and all the former
8313 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
8314 someone should address this issue.
8316 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

8415 2000-10-02 Akim Demaille <akim@epita.fr>
8417 `user_toknums' is output as a `short[]' in `output.c', while it is
8418 defined as a `int[]' in `reader.c'. For consistency with the
8419 other output tables, `user_toknums' is now defined as a table of

8463 * src/system.h: Define PARAMS.

8686 of the lhs of the rule (by default ranging from the location of

8688 or, if the rhs is empty, YYLLOC).
8690 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
8692 (yyparse): When providing a default semantic action, provide a
8693 default location action.
8694 (after the $): No longer change `*YYLSP', just stack YYLOC the
8695 same way you stack YYVAL.
8696 * src/reader.c (read_declarations): Use warns.

8723 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
8724 One `#if YYDEBUG' remains, since it uses variables which are

8729 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
